Residential Self Selection and Rail Commuting: A Nested Logit Analysis  

E-Print Network (OSTI)

An error was discovered in the original Table 1 of this study. Notably, the Inclusive terms for the upper-nest model were incorrectly calculated thus the theta terms were in error. This revised working paper corrects this error. Also, the corrected upper nest model has a slightly different specification than originally shown in Table 1 in order to satisfy the condition that the theta values lie between 0 and 1. Some additional text is added to the original working paper regarding the new upper level model, however none of the substantive findings or conclusions of the research change as a result. The additional variables added to the upper nest model reveal that low automobile ownership levels tended to be associated with transit-oriented living. We acknowledge that automobile ownership likely both influences and is influenced by transit-oriented living, thus the coefficient on the automobile ownership variables could be subject to endogeneity bias. The revised equation also shows that controlling for other variables in the equation, having individuals 55 years of age and above in a household reduced the likelihood of living near transit. It is also noted that the estimated coefficients in the lower nest binomial logit models for predicting rail commuting (shown in the right-hand

Nesting Habits of Owls Nesting Habits of Owls Nature Bulletin No. 624 January 14, 1961 Forest Preserve District of Cook County Daniel Ryan, President Roberts Mann, Conservation Editor David H. Thompson, Senior Naturalist NESTING HABITS OF OWLS From all of the information available it appears to us that, amongst the owls, there is greater variation in where and how they nest than in any other group of birds. Two nesting characteristics, however, are common to all owls. The eggs are nearly spherical and white, or off-white, without any markings. Also, a nesting female does not lay one egg per day, as most birds do, but at intervals of two or more days -- sometimes several. In extreme cases there may be a fresh egg, others incubating, and a newly hatched fledgling -- all in the same nest.

A Note on the Estimation of the Multinomial Logistic Model with Correlated Responses  

E-Print Network (OSTI)

We show how multinomial logistic models with correlated responses can be estimated within SAS software. To achieve this, random effects and marginal models are introduced and the respective SAS code is given. An example data set on physicians ’ recommendations and preferences in traumatic brain injury rehabilitation is used for illustration. The main motivation for this work are two recent papers that recommend estimating multinomial logistic models with correlated responses by using a Poisson likelihood which is statistically correct but computationally inefficient.

Bird Nest Predation  

NLE Websites -- All DOE Office Websites (Extended Search)

Bird Nest Predation Bird Nest Predation Name: Susan Location: N/A Country: N/A Date: N/A Question: On the 18th of April, a pair of Northern Cardinals selected a nest site near the top of a dense, 8 foot holly tree, a foundation planting that obscures about 1/4 of our open front porch. They located the nest under the overhang of the roof, facing our front door. By the 21st, a clutch of three eggs had been laid and Mrs. C began to sit on the nest. We succeeded at keeping a low profile, despite the near proximity to our main entrance. She was relaxed and seemingly unworried by our quiet comings and goings. Yesterday morning, all was well, but sometime around midday, after almost a week of incubation, all three eggs and, it appears, Mrs. C, vanished without a trace! There is no obvious disturbance or damage to the nest or the immediate area. The interior of the nest is pristine ~ no feathers, eggshell bits, membrane material. Cats are rarely a problem. In addition to the typical Blue Jays and Crows, we have a lot of squirrels, raccoons, opossums, skunks and even a pair of red-tail hawks on our wooded acre and the surrounds. Due to, I believe, some nearby housing construction, I have observed a opossum during the day several times this past week and have noticed a new arrival, a woodchuck. With temperatures in the 50's, I think it is too chilly for snakes to be active. What would be your best guess as to what happened? Any chance the pair will return to the same nest and try again?

Serenbe Nest Cottages  

SciTech Connect

As part of the NAHB Research Center Industry Partnership, Southface partnered with Martin Dodson Builders and the Serenbe community on the construction of a new test home in the suburbs of Atlanta, GA in the mixed humid climate zone. The most recent subdivision within the Serenbe community, the Nest, will contain 15 small footprint cottage style homes, and Southface has selected Lot Nine, as the test home for this study. This Nest subdivision serves as a project showcase for both the builder partner and the Serenbe community as a whole. The planning and design incorporated into the Nest cottages will be implemented in each home within the subdivision. These homes addresses Building America Savings targets and serve as a basis of design for other homes Martin Dodson plans to build within the Serenbe community.

Fiber Tracking Cylinder Nesting  

SciTech Connect

The fiber tracker consists of 8 concentric carbon fiber cylinders of varying diameters, from 399mm to 1032.2mm and two different lengths. 1.66 and 2.52 meters. Each completed cylinder is covered over the entire o.d. with scintillating fiber ribbons with a connector on each ribbon. These ribbons are axial (parallel to the beam line) at one end and stereo (at 3 deg. to the beam line) at the other. The ribbon connectors have dowel pins which are used to match with the connectors on the wave guide ribbons. These dowel pins are also used during the nesting operation, locating and positioning measurements. The nesting operation is the insertion of one cylinder into another, aligning them with one another and fastening them together into a homogeneous assembly. For ease of assembly. the nesting operation is accomplished working from largest diameter to smallest. Although the completed assembly of all 8 cylinders glued and bolted together is very stiff. individual cylinders are relatively flexible. Therefore. during this operation, No.8 must be supported in a manner which maintains its integrity and yet allows the insertion of No.7. This is accomplished by essentially building a set of dummy end plates which replicate a No.9 cylinder. These end plates are mounted on a wheeled cart that becomes the nesting cart. Provisions for a protective cover fastened to these rings has been made and will be incorporated in finished product. These covers can be easily removed for access to No.8 and/or the connection of No.8 to No.9. Another wheeled cart, transfer cart, is used to push a completed cylinder into the cylinder(s) already mounted in the nesting cart.

A new method for multinomial inference using Dempster-Shafer theory  

SciTech Connect

A new method for multinomial inference is proposed by representing the cell probabilities as unordered segments on the unit interval and following Dempster-Shafer (DS) theory. The resulting DS posterior is then strengthened to improve symmetry and learning properties with the final posterior model being characterized by a Dirichlet distribution. In addition to computational simplicity, the new model has desirable invariance properties related to category permutations, refinements, and coarsenings. Furthemore, posterior inference on relative probabilities amongst certain cells depends only on data for the cells in question. Finally, the model is quite flexible with regard to parameterization and the range of testable assertions. Comparisons are made to existing methods and illustrated with two examples.

Importance Nested Sampling and the MultiNest Algorithm  

E-Print Network (OSTI)

Bayesian inference involves two main computational challenges. First, in estimating the parameters of some model for the data, the posterior distribution may well be highly multi-modal: a regime in which the convergence to stationarity of traditional Markov Chain Monte Carlo (MCMC) techniques becomes incredibly slow. Second, in selecting between a set of competing models the necessary estimation of the Bayesian evidence for each is, by definition, a (possibly high-dimensional) integration over the entire parameter space; again this can be a daunting computational task, although new Monte Carlo (MC) integration algorithms offer solutions of ever increasing efficiency. Nested sampling (NS) is one such contemporary MC strategy targeted at calculation of the Bayesian evidence, but which also enables posterior inference as a by-product, thereby allowing simultaneous parameter estimation and model selection. The widely-used MultiNest algorithm presents a particularly efficient implementation of the NS technique for...

Nested-cone transformer antenna  

DOE Patents (OSTI)

A plurality of conical transmission lines are concentrically nested to form an output antenna for pulsed-power, radio-frequency, and microwave sources. The diverging conical conductors enable a high power input density across a bulk dielectric to be reduced below a breakdown power density at the antenna interface with the transmitting medium. The plurality of cones maintain a spacing between conductors which minimizes the generation of high order modes between the conductors. Further, the power input feeds are isolated at the input while enabling the output electromagnetic waves to add at the transmission interface. Thus, very large power signals from a pulse rf, or microwave source can be radiated. 6 figures.

Co-relation of Variables Involved in the Occurrence of Crane Accidents in U.S. through Logit Modeling.  

E-Print Network (OSTI)

One of the primary reasons of the escalating rates of injuries and fatalities in the construction industry is the ever so complex, dynamic and continually changing nature of construction work. Use of cranes has become imperative to overcome technical challenges, which has lead to escalation of danger on a construction site. Data from OSHA show that crane accidents have increased rapidly from 2000 to 2004. By analyzing the characteristics of all the crane accident inspections, we can better understand the significance of the many variables involved in a crane accident. For this research, data were collected from the U.S. Department of Labor website via the OSHA database. The data encompass crane accident inspections for all the states. The data were divided into categories with respect to accident types, construction operations, degree of accident, fault, contributing factors, crane types, victim’s occupation, organs affected and load. Descriptive analysis was performed to compliment the previous studies, the only difference being that both fatal and non-fatal accidents have been considered. Multinomial regression has been applied to derive probability models and correlation between different accident types and the factors involved for each crane accident type. A log likelihood test as well as chi-square test was performed to validate the models. The results show that electrocution, crane tip over and crushed during assembly/disassembly have more probability of occurrence than other accident types. Load is not a significant factor for the crane accidents, and manual fault is more probable a cause for crane accident than is technical fault. Construction operations identified in the research were found to be significant for all the crane accident types. Mobile crawler crane, mobile truck crane and tower crane were found to be more susceptible. These probability models are limited as far as the inculcation of unforeseen variables in construction accidents are concerned. In fact, these models utilize the past to portray the future, and therefore significant change in the variables involved is required to be added to attain correct and expedient results.

Development of the Nested Fiber Filter  

SciTech Connect

Battelle, has tested the Nested Fiber Filter (NFF) as a particulate control device for high temperature, high-pressure (HTHP) applications. Battelle funded initial bench-scale tests which were the basis for patents and a concept applying the NFF. Subsequent parametric tests in a 6-inch diameter reactor established excellent particulate capture performance, > 99 percent, for conditions up to 1600 F and 6 atmospheres. Effective cleaning/regeneration of the NFF was achieved in the 6-inch scale with acoustic and mechanical vibration. A pulse combustor was tested in an integrated NFF arrangement because of compatibility with the HTBP conditions. This arrangement provided the basis for larger scale tests under the subject contract. A 6-ft[sup 2] test module was designed and installed with an existing fluidized bed combustor for additional development and testing.

Qualitative choice modeling of energy-conservation decisions: a micro-economic analysis of the determinants of residential space-heating energy demand  

Science Conference Proceedings (OSTI)

This study develops an economic model of household decisions to install major conservation measures such as storm windows, attic insulation, and wall insulation. The structural core of the model is the neoclassical economic paradigm of constrained discounted expected utility maximization. Household choices are modeled as being determined by household preferences across space-heating comfort levels and a composite of all other goods and services. These preferences interact with alternative household budget constraints which are determined by the household's conservation decisions. Nested Logit estimation techniques, using the observed discrete choices of a representative sample of households (in owner-occupied, single-family dwellings), are shown to be superior to simple Multinomial Logit estimation. This superiority arises from the importance of correlation among the error terms associated with indirect utility derived from certain subsets of available conservation alternatives.

It is important to study effective and efficient transformation techniques to increase parallelism for nested loops. In this paper, we propose a novel technique, iterational retiming, that can satisfy any given timing constraint by achieving full parallelism for iterations in a partition. Theorems and efficient algorithms are proposed for iterational retiming. The experimental results show that iterational retiming is a promising technique for parallel embedded systems. It can achieve 87% improvement over software pipelining and 88 % improvement over loop unfolding on average.

Optimal sequential transmission over broadcast channel with nested feedback  

E-Print Network (OSTI)

We consider the optimal design of sequential transmission over broadcast channel with nested feedback. Nested feedback means that the channel output of the outer channel is also available at the decoder of the inner channel. We model the communication system as a decentralized team with three decision makers---the encoder and the two decoders. Structure of encoding and decoding strategies that minimize a total distortion measure over a finite horizon are determined. The results are applicable for real-time communication as well as for the information theoretic setup.

Nesting ecology of wood thrush (Turdidae: Passeriformes) in hardwood forests of South Carolina  

DOE Green Energy (OSTI)

The nesting success of the Wood Thrush (Hylocichla mustelina) in bottomland and upland forests in South Carolina. Twenty-one of 26 nests were located in bottomland sites, and 76.2% of these nests were in narrow (<150-m wide) bottomland corridors. No nests were found in upland sites enclosed by fields. The Mayfield success rate for 20 nests was 35.3%. All nest failures were attributed to predation, no nests were parasitized by Brown-headed Cowbirds (Molothrus ater). Nest sites were characterized by a dense overstory and a moderately developed understory. Bottomland hardwoods, especially relatively narrow corridors, appear to provide suitable nesting habitat for Wood Thrush in this region. Brood parasitism by Brown-headed Cowbirds does not appear to be a significant factor in the failure of Wood Thrush nests in these sites.

Alternative fuels and vehicles choice model  

DOE Green Energy (OSTI)

This report describes the theory and implementation of a model of alternative fuel and vehicle choice (AFVC), designed for use with the US Department of Energy`s Alternative Fuels Trade Model (AFTM). The AFTM is a static equilibrium model of the world supply and demand for liquid fuels, encompassing resource production, conversion processes, transportation, and consumption. The AFTM also includes fuel-switching behavior by incorporating multinomial logit-type equations for choice of alternative fuel vehicles and alternative fuels. This allows the model to solve for market shares of vehicles and fuels, as well as for fuel prices and quantities. The AFVC model includes fuel-flexible, bi-fuel, and dedicated fuel vehicles. For multi-fuel vehicles, the choice of fuel is subsumed within the vehicle choice framework, resulting in a nested multinomial logit design. The nesting is shown to be required by the different price elasticities of fuel and vehicle choice. A unique feature of the AFVC is that its parameters are derived directly from the characteristics of alternative fuels and vehicle technologies, together with a few key assumptions about consumer behavior. This not only establishes a direct link between assumptions and model predictions, but facilitates sensitivity testing, as well. The implementation of the AFVC model as a spreadsheet is also described.

Analysis of Enriched Uranyl Nitrate in Nested Annular Tank Array  

SciTech Connect

Two series of experiments were performed at the Rocky Flats Critical Mass Laboratory during the 1980s using highly enriched (93%) uranyl nitrate solution in annular tanks. [1, 2] Tanks were of typical sizes found in nuclear production plants. Experiments looked at tanks of varying radii in a co-located set of nested tanks, a 1 by 2 array, and a 1 by 3 array. The co-located set of tanks had been analyzed previously [3] as a benchmark for inclusion within the International Handbook of Evaluated Criticality Safety Benchmark Experiments. [4] The current study represents the benchmark analysis of the 1 by 3 array of a series of nested annular tanks. Of the seventeen configurations performed in this set of experiments, twelve were evaluated and nine were judged as acceptable benchmarks.

Intermediate Vapor Expansion Distillation and Nested Enrichment Cascade Distillation  

E-Print Network (OSTI)

Although it is known that incorporating an intermediate reboiler or reflux condenser in a distillation column will improve column efficiency by 15 to 100%, there has been little use of this technique to date." Intermediate vapor compression heat pumping was recently introduced as one practical means of achieving this benefit. Introduced in this paper are two new means having added advantages over compression: intermediate vapor expansion heat pumping, and nested enrichment cascades. In both cases the efficiency advantage is obtained without requiring import of shaft work. With intermediate vapor expansion, the expander is more efficient and less costly than the compressor which achieves comparable improvement in distillation efficiency. With the "nested enrichment" technique, the increased efficiency is obtained without requiring either compressors or expanders.

Nested cycles in large triangulations and crossing-critical graphs  

E-Print Network (OSTI)

We show that every sufficiently large plane triangulation has a large collection of nested cycles that either are pairwise disjoint, or pairwise intersect in exactly one vertex, or pairwise intersect in exactly two vertices. We apply this result to show that for each fixed positive integer $k$, there are only finitely many $k$-crossing-critical simple graphs of average degree at least six. Combined with the recent constructions of crossing-critical graphs given by Bokal, this settles the question of for which numbers $q>0$ there is an infinite family of $k$-crossing-critical simple graphs of average degree $q$.

Force-Gradient Nested Multirate Methods for Hamiltonian System  

E-Print Network (OSTI)

Force-gradient decomposition methods are used to improve the energy preservation of symplectic schemes applied to Hamiltonian systems. If the potential is composed of different parts with strongly varying dynamics, this multirate potential can be exploited by coupling force-gradient decomposition methods with splitting techniques for multi-time scale problems to further increase the accuracy of the scheme and reduce the computational costs. In this paper, we derive novel force-gradient nested methods and test them numerically. Such methods can be used to increase the acceptance rate for the molecular dynamics step of the Hybrid Monte Carlo algorithm (HMC) and hence improve its computational efficiency.

Rapidly Rotating Suns and Active Nests of Convection  

E-Print Network (OSTI)

In the solar convection zone, rotation couples with intensely turbulent convection to drive a strong differential rotation and achieve complex magnetic dynamo action. Our sun must have rotated more rapidly in its past, as is suggested by observations of many rapidly rotating young solar-type stars. Here we explore the effects of more rapid rotation on the global-scale patterns of convection in such stars and the flows of differential rotation and meridional circulation which are self-consistently established. The convection in these systems is richly time dependent and in our most rapidly rotating suns a striking pattern of localized convection emerges. Convection near the equator in these systems is dominated by one or two nests in longitude of locally enhanced convection, with quiescent streaming flow in between at the highest rotation rates. These active nests of convection maintain a strong differential rotation despite their small size. The structure of differential rotation is similar in all of our more rapidly rotating suns, with fast equators and slower poles. We find that the total shear in differential rotation Delta Omega grows with more rapid rotation while the relative shear Delta Omega/Omega_0 decreases. In contrast, at more rapid rotation the meridional circulations decrease in energy and peak velocities and break into multiple cells of circulation in both radius and latitude.

Nesting ecology of dickcissels on reclaimed surface-mined lands in Freestone County, Texas  

E-Print Network (OSTI)

Surface mining and subsequent reclamation often results in the establishment of large areas of grassland that can benefit wildlife. Grasslands have declined substantially over the last 150 years, resulting in declines of many grassland birds. The dickcissel (Spiza americana), a neotropical migrant, is one such bird whose numbers have declined in the last 30 years due to habitat loss, increased nest predation and parasitism, and over harvest (lethally controlled as an agricultural pest on its wintering range in Central and South America). Reclaimed surface-mined lands have been documented to provide important breeding habitat for dickcissels in the United States, emphasizing the importance of reclamation efforts. Objectives were to understand specific aspects of dickcissel nesting ecology (i.e., nest-site selection, nest success, and nest parasitism, and identification of nest predators) on 2 spatial scales on TXU Energy?s Big Brown Mine, near Fairfield, Texas, and to subsequently provide TXU Energy with recommendations to improve reclaimed areas as breeding habitat for dickcissels. I examined the influence of nest-site vegetation characteristics and the effects of field-level spatial factors on dickcissel nesting ecology on 2 sites reclaimed as wildlife habitat. Additionally, I developed a novel technique to identify predators at active nests during the 2003 field season. During 2002?2003, 119 nests were monitored. On smaller spatial scales, dickcissels were likely to select nest-sites with low vegetation, high densities of bunchgrasses and tall forbs, and areas with higher clover content. Probability of nest success increased with nest heights and vegetation heights above the nest, characteristics associated with woody nesting substrates. Woody nesting substrates were selected and bunchgrasses were avoided. Oak (Quercus spp.) saplings remained an important nesting substrate throughout the breeding season. On a larger scale, nest-site selection was likely to occur farther from wooded riparian areas and closer to recently-reclaimed areas. Nest parasitism was likely to occur near roads and wooded riparian areas. Results suggest reclaimed areas could be improved by planting more bunchgrasses, tall forbs (e.g., curly-cup gumweed [Grindelia squarrosa] and sunflower [Helianthus spp.]), clover (Trifolium spp.), and oaks (a preferred nesting substrate associated with higher survival rates). Larger-scale analysis suggests that larger tracts of wildlife areas should be created with wooded riparian areas comprising a minimal portion of a field?s edge.

Nested methylation-specific polymerase chain reaction cancer detection method  

DOE Patents (OSTI)

A molecular marker-based method for monitoring and detecting cancer in humans. Aberrant methylation of gene promoters is a marker for cancer risk in humans. A two-stage, or "nested" polymerase chain reaction method is disclosed for detecting methylated DNA sequences at sufficiently high levels of sensitivity to permit cancer screening in biological fluid samples, such as sputum, obtained non-invasively. The method is for detecting the aberrant methylation of the p16 gene, O 6-methylguanine-DNA methyltransferase gene, Death-associated protein kinase gene, RAS-associated family 1 gene, or other gene promoters. The method offers a potentially powerful approach to population-based screening for the detection of lung and other cancers.

Variation in the Structure of Bird Nests between Northern Manitoba and Southeastern Ontario  

E-Print Network (OSTI)

Traits that converge in appearance under similar environmental conditions among phylogenetically independent lineages are thought to represent adaptations to local environments. We tested for convergence in nest morphology and composition of birds breeding in two ecologically different locations in Canada: Churchill in northern Manitoba and Elgin in southeastern Ontario. We examined nests from four families of passerine birds (Turdidae: Turdus, Parulidae: Dendroica, Emberizidae: Passerculus and Fringillidae: Carduelis) where closely related populations or species breed in both locations. Nests of American Robins, Yellow Warblers, and Carduelis finches had heavier nest masses, and tended to have thicker nestwalls, in northern Manitoba compared with conspecifics or congenerics breeding in southeastern Ontario. Together, all species showed evidence for wider internal and external nest-cup diameters in northern Manitoba, while individual species showed varying patterns for internal nest-cup and external nest depths. American Robins, Yellow Warblers, and Carduelis finches in northern Manitoba achieved heavier nest masses in different ways. American Robins increased all materials in similar proportions, and Yellow Warblers and Common Redpolls used greater amounts of select materials. While changes in nest composition vary uniquely for each species, the pattern of larger nests in northern Manitoba compared to southeastern Ontario in three of our four phylogenetically-independent comparisons suggests that birds are adapting to similar selective

On August 11, 1990 during an ornithological survey at the True/Mid Pacific Geothermal Venture proposed well site No.2, a Hawaiian hawk (Buteo solitarius) nest with a nestling was found approximately 430 feet from the proposed well pad clearing. The U.S. Fish and Wildlife Service and the State of Hawaii have listed the Hawaiian hawk as an endangered species. Future development in this area could be impacted by the presence of this endangered avian species and its nest in such close proximity to the proposed well site. This report summarizes the results of observations at the nest on August 12, 19 and 25 and September 2, 1990.

The use of nested sampling in the extraction of polarisation observables at CLAS  

SciTech Connect

The extraction of polarisation observables from photoproduction experiments provides an insight into the spectrum of nucleon resonances and the 'missing resonance' problem. Experiments carried out at JLab, Mainz and Bonn cover a wide range of reactions, which will soon result in the first 'complete measurement' in pseudoscalar meson photoproduction. Traditionally, these measurements have been analysed using frequentist statistics, where parameters are extracted by fitting distributions. An alternative method is the application of Bayesian statistics, where any existing knowledge about the results can be used in the initial conditions. One such application of this is nested sampling. This work discusses nested sampling and how it can be applied to the extraction of spin observables.

High-temperature, high-pressure bonding of nested tubular metallic components  

DOE Patents (OSTI)

This invention is a tool for effecting high-temperature, high-compression bonding between the confronting faces of nested, tubular, metallic components. In a typical application, the tool is used to produce tubular target assemblies for irradiation in nuclear reactors or particle accelerators, the target assembly comprising a uranium foil and an aluminum-alloy substrate. The tool preferably is composed throughout of graphite. It comprises a tubular restraining member in which a mechanically expandable tubular core is mounted to form an annulus with the member. The components to be bonded are mounted in nested relation in the annulus. The expandable core is formed of individually movable, axially elongated segments whose outer faces cooperatively define a cylindrical pressing surface and whose inner faces cooperatively define two opposed, inwardly tapered, axial bores. Tapered rams extend respectively into the bores. The loaded tool is mounted in a conventional hot-press provided with evacuation means, heaters for maintaining its interior at bonding temperature, and hydraulic cylinders for maintaining a selected inwardly directed pressure on the tapered rams. With the hot-press evacuated and the loaded tool at the desired temperature, the cylinders are actuated to apply the selected pressure to the rams. The rams in turn expand the segmented core to maintain the nested components in compression against the restraining member. These conditions are maintained until the confronting faces of the nested components are joined in a continuous, uniform bond characterized by high thermal conductivity.

MultiNest: an efficient and robust Bayesian inference tool for cosmology and particle physics  

E-Print Network (OSTI)

We present further development and the first public release of our multimodal nested sampling algorithm, called MultiNest. This Bayesian inference tool calculates the evidence, with an associated error estimate, and produces posterior samples from distributions that may contain multiple modes and pronounced (curving) degeneracies in high dimensions. The developments presented here lead to further substantial improvements in sampling efficiency and robustness, as compared to the original algorithm presented in Feroz & Hobson (2008), which itself significantly outperformed existing MCMC techniques in a wide range of astrophysical inference problems. The accuracy and economy of the MultiNest algorithm is demonstrated by application to two toy problems and to a cosmological inference problem focussing on the extension of the vanilla $\\Lambda$CDM model to include spatial curvature and a varying equation of state for dark energy. The MultiNest software, which is fully parallelized using MPI and includes an interface to CosmoMC, is available at http://www.mrao.cam.ac.uk/software/multinest/. It will also be released as part of the SuperBayeS package, for the analysis of supersymmetric theories of particle physics, at http://www.superbayes.org

Regional climate change scenarios over the United States produced with a nested regional climate model  

Science Conference Proceedings (OSTI)

Two continuous 31/2-year-long climate simulation over the continental United States are discussed, one of present-day conditions and one for conditions under double carbon dioxide concentration, conducted with a limited area model (LAM) nested in a general circulation model (GCM). The models used are a version of the NCAR Community Climate Model (CCM) at rhomboidal 15 spectral resolution and the climate version of the NCAR/Penn State mesoscale model (MM4) at 60-km gridpoint spacing. For present-day conditions the model temperatures are within 1[degrees]-2[degrees]C of observations except over the Great Lakes region, where temperature is overpredicted. The CCM overpredicts precipitation throughout the continental United States (overall by about 60%) and especially over the West (by up to 300%). The nested MM4 overpredicts precipitation over the West but underpredicts it over the eastern United States. In addition, it produces a large amount of topographically and lake-induced sub-GCM grid-scale detail that compares well with available high-resolution climate data. Overall, the nested MM4 reproduces observed spatial and seasonal precipitation patterns better than the driving CCM. Doubled carbon dioxide-induced temperature change scenarios produced by the two models generally differ by less than several tenths of a degree except over the Great Lakes region where, because of the presence of the lakes in the nested model, the two model scenarios differ by more than one degree. Conversely, precipitation change scenarios from the two model simulations can locally differ in magnitude, sign, spatial, and seasonal detail. These differences are associated with topographical features in the MM4, such as the presence of steep coastal ranges in the western United States. This work illustrates the feasibility of the use of the nested modeling technique for long-term regional climate simulation. 43 refs., 19 figs., 6 tabs.

Household appliance choice: revision of REEPS behavioral models. Final report  

Science Conference Proceedings (OSTI)

This report describes the analysis of household decisions to install space heating, central cooling, and water heating in new housing as well as decisions to own freezers and second refrigerators. This analysis was conducted as part of the enhancements to the Residential End-Use Energy Planning System (REEPS) under EPRI project RP1918-1. The empirical models used in this analysis were the multinomial logit and its generalization the nested logit. The choice model parameters were estimated statistically on national and regional survey data. The results show that capital and operating costs are significant determinants of appliance market penetrations, and the relative magnitudes of the cost coefficients imply discount rates ranging from 3.4 to twenty-one percent. Several tests were conducted to examine the temporal and geographical stability of the key parameters. The estimated parameters have been incorporated into the REEPS computer code. The revised version of REEPS is now available on a limited release basis to EPRI member utilities for testing on their system.

Collection Rule and an Integrated Cell Culture-Nested PCR Procedure  

E-Print Network (OSTI)

We evaluated the use of an integrated cell culture-reverse transcription-PCR (ICC-RT-PCR) procedure coupled with nested PCR to detect human astroviruses, enteroviruses, and adenovirus types 40 and 41 in surface water samples that were collected and evaluated by using the Information Collection Rule (ICR) method. The results obtained with the ICC-RT-PCR–nested PCR method were compared to the results obtained with the total culturable virus assay–most-probable-number (TCVA-MPN) method, the method recommended by the U.S. Environmental Protection Agency for monitoring viruses in surface and finished waters. Twenty-nine ICR surface water samples were analyzed. Viruses were concentrated by using filter adsorption-beef extract elution and organic flocculation techniques, and then the preparations were evaluated for viruses by visualizing cytopathic effects in the Buffalo green monkey kidney (BGMK) cell line. In the ICC-RT-PCR–nested PCR technique we used Caco-2 cells to propagate astroviruses and enteroviruses (ICC step), and we used BGMK cells to propagate adenovirus types 40 and 41, as well as enteroviruses. Fifteen of the 29 samples (51.7%) were positive for astrovirus as determined by the ICC-RT-PCR–nested PCR method, and eight of these samples (27.5%) contained infectious astrovirus. Seventeen of the 29 samples (58.6%) were positive for enteroviruses when the BGMK cell line was used, and six (27.6%) of these samples were determined to be infectious. Fourteen of the 29 samples (48.3%) were positive for adenovirus types 40 and 41, and 11

Nesting large-eddy simulations within mesoscale simulations for wind energy applications  

DOE Green Energy (OSTI)

With increasing demand for more accurate atmospheric simulations for wind turbine micrositing, for operational wind power forecasting, and for more reliable turbine design, simulations of atmospheric flow with resolution of tens of meters or higher are required. These time-dependent large-eddy simulations (LES), which resolve individual atmospheric eddies on length scales smaller than turbine blades and account for complex terrain, are possible with a range of commercial and open-source software, including the Weather Research and Forecasting (WRF) model. In addition to 'local' sources of turbulence within an LES domain, changing weather conditions outside the domain can also affect flow, suggesting that a mesoscale model provide boundary conditions to the large-eddy simulations. Nesting a large-eddy simulation within a mesoscale model requires nuanced representations of turbulence. Our group has improved the Weather and Research Forecasting model's (WRF) LES capability by implementing the Nonlinear Backscatter and Anisotropy (NBA) subfilter stress model following Kosovic (1997) and an explicit filtering and reconstruction technique to compute the Resolvable Subfilter-Scale (RSFS) stresses (following Chow et al, 2005). We have also implemented an immersed boundary method (IBM) in WRF to accommodate complex terrain. These new models improve WRF's LES capabilities over complex terrain and in stable atmospheric conditions. We demonstrate approaches to nesting LES within a mesoscale simulation for farms of wind turbines in hilly regions. Results are sensitive to the nesting method, indicating that care must be taken to provide appropriate boundary conditions, and to allow adequate spin-up of turbulence in the LES domain.

Shock model description of the interaction radiation pulse in nested wire array z-pinches  

Science Conference Proceedings (OSTI)

Bow shock structures are observed in a nested wire array z-pinch as ablation streams from the outer array pass the inner array. The jump in plasma conditions across these shocks results in an enhancement of snowplow emission from the imploding plasma piston. Results from a snowplow model modified to account for the shock jumps are discussed and compared to experimental data from MAGPIE. Magnetohydrodynamic simulations indicate that this is the primary heating mechanism responsible for the interaction pulse recorded on the Z generator, which is required for pulse shaping for inertial confinement fusion.

Comprehensive analysis of radiative properties of brass and Al arranged in nested cylindrical wire arrays.  

SciTech Connect

Experimental results of nested cylindrical wire arrays (NCWA) consisting of brass (70% Cu and 30% Zn) wires on one array and Al (5056, 5% Mg) wires on the other array performed on the UNR Zebra generator at 1.0 MA current are compared and analyzed. Specifically, radiative properties of K-shell Al and Mg ions and L-shell Cu and Zn ions are compared as functions of the placements of the brass and Al wires on the inner and outer arrays. A full diagnostic set which included more than ten different beam-lines was implemented. Identical loads were fielded to allow the timing of time-gated pinhole and x-ray spectrometers to be shifted to get a more complete understanding of the evolution of plasma parameters over the x-ray pulse. The importance of the study of NCWAs with different wire materials is discussed.

Improved parallel data partitioning by nested dissection with applications to information retrieval.  

Science Conference Proceedings (OSTI)

The computational work in many information retrieval and analysis algorithms is based on sparse linear algebra. Sparse matrix-vector multiplication is a common kernel in many of these computations. Thus, an important related combinatorial problem in parallel computing is how to distribute the matrix and the vectors among processors so as to minimize the communication cost. We focus on minimizing the total communication volume while keeping the computation balanced across processes. In [1], the first two authors presented a new 2D partitioning method, the nested dissection partitioning algorithm. In this paper, we improve on that algorithm and show that it is a good option for data partitioning in information retrieval. We also show partitioning time can be substantially reduced by using the SCOTCH software, and quality improves in some cases, too.

Bayesian evidence: can we beat MultiNest using traditional MCMC methods?  

E-Print Network (OSTI)

Markov Chain Monte Carlo (MCMC) methods have revolutionised Bayesian data analysis over the years by making the direct computation of posterior probability densities feasible on modern workstations. However, the calculation of the prior predictive, the Bayesian evidence, has proved to be notoriously difficult with standard techniques. In this work a method is presented that lets one calculate the Bayesian evidence using nothing but the results from standard MCMC algorithms, like Metropolis-Hastings. This new method is compared to other methods like MultiNest, and greatly outperforms the latter in several cases. One of the toy problems considered in this work is the analysis of mock pulsar timing data, as encountered in pulsar timing array projects. This method is expected to be useful as well in other problems in astrophysics, cosmology and particle physics.

Rapid Rotation, Active Nests of Convection and Global-scale Flows in Solar-like Stars  

E-Print Network (OSTI)

In the solar convection zone, rotation couples with intensely turbulent convection to build global-scale flows of differential rotation and meridional circulation. Our sun must have rotated more rapidly in its past, as is suggested by observations of many rapidly rotating young solar-type stars. Here we explore the effects of more rapid rotation on the patterns of convection in such stars and the global-scale flows which are self-consistently established. The convection in these systems is richly time dependent and in our most rapidly rotating suns a striking pattern of spatially localized convection emerges. Convection near the equator in these systems is dominated by one or two patches of locally enhanced convection, with nearly quiescent streaming flow in between at the highest rotation rates. These active nests of convection maintain a strong differential rotation despite their small size. The structure of differential rotation is similar in all of our more rapidly rotating suns, with fast equators and slower poles. We find that the total shear in differential rotation, as measured by latitudinal angular velocity contrast, Delta_Omega, increases with more rapid rotation while the relative shear, Delta_Omega/Omega, decreases. In contrast, at more rapid rotation the meridional circulations decrease in both energy and peak velocities and break into multiple cells of circulation in both radius and latitude.

Analytical examples of reversal current, zero core current, and surface current, toroidal magnetostatic equilibria with nested flux surfaces  

SciTech Connect

We present exact analytical examples of three types of axisymmetric toroidal magnetostatic equilibria with nested flux surfaces: (1) current reversal equilibria, for which the net toroidal current switches from a negative to a positive value when moving away from the magnetic axis; these equilibria have a non-monotonic pressure profile, in accordance with Hammett et al.'s theorem stating that the pressure on the current reversal surface has to exceed the volume-averaged pressure within that surface; (2) zero core current equilibria, in which the toroidal current density vanishes inside some flux surface; and (3) surface current equilibria, constituted of an arbitrary number of nested layers inside which the plasma pressure is constant and the magnetic field force-free, with two adjacent layers being separated by a current sheet. All these configurations are obtained by shaping in an adequate way the arbitrary function which intervenes in the class of generalized isodynamic equilibria first constructed by Palumbo and recovered later on by Bishop and Taylor. A derivation of these equilibria by a method slightly different from Palumbo's is given in an Appendix.

A Plug-in Hybrid Consumer Choice Model with Detailed Market Segmentation  

DOE Green Energy (OSTI)

This paper describes a consumer choice model for projecting U.S. demand for plug-in hybrid electric vehicles (PHEV) in competition among 13 light-duty vehicle technologies over the period 2005-2050. New car buyers are disaggregated by region, residential area, attitude toward technology risk, vehicle usage intensity, home parking and work recharging. The nested multinomial logit (NMNL) model of vehicle choice incorporates daily vehicle usage distributions, refueling and recharging availability, technology learning by doing, and diversity of choice among makes and models. Illustrative results are presented for a Base Case, calibrated to the Annual Energy Outlook (AEO) 2009 Reference Updated Case, and an optimistic technology scenario reflecting achievement of U.S. Department of Energy s (DOE s) FreedomCAR goals. PHEV market success is highly dependent on the degree of technological progress assumed. PHEV sales reach one million in 2037 in the Base Case but in 2020 in the FreedomCARGoals Case. In the FreedomCARGoals Case, PHEV cumulative sales reach 1.5 million by 2015. Together with efficiency improvements in other technologies, petroleum use in 2050 is reduced by about 45% from the 2005 level. After technological progress, PHEV s market success appears to be most sensitive to recharging availability, consumers attitudes toward novel echnologies, and vehicle usage intensity. Successful market penetration of PHEVs helps bring down battery costs for electric vehicles (EVs), resulting in a significant EV market share after 2040.

This engineering task plan identifies the resources, responsibilities, and schedules for the development and deployment of a mobile, variable depth sampling system and an at-tank analysis system. The mobile, variable depth sampling system concept was developed after a cost assessment indicated a high cost for multiple deployments of the nested, fixed-depth sampling system. The sampling will provide double-shell tank (DST) staging tank waste samples for assuring the readiness of the waste for shipment to the LAW/HLW plant for treatment and immobilization. The at-tank analysis system will provide ''real-time'' assessments of the samples' chemical and physical properties. These systems support the Hanford Phase 1B vitrification project.

Highly Enriched Uranyl Nitrate in Annular Tanks with Concrete Reflection: 1 x 3 Line Array of Nested Pairs of Tanks  

Science Conference Proceedings (OSTI)

A series of seven experiments were performed at the Rocky Flats Critical Mass Laboratory beginning in August, 1980 (References 1 and 2). Highly enriched uranyl nitrate solution was introduced into a 1-3 linear array of nested stainless steel annular tanks. The tanks were inside a concrete enclosure, with various moderator and absorber materials placed inside and/or between the tanks. These moderators and absorbers included boron-free concrete, borated concrete, borated plaster, and cadmium. Two configurations included placing bottles of highly enriched uranyl nitrate between tanks externally. Another experiment involved nested hemispheres of highly enriched uranium placed between tanks externally. These three configurations are not evaluated in this report. The experiments evaluated here are part of a series of experiments, one set of which is evaluated in HEU-SOL-THERM-033. The experiments in this and HEU-SOL-THERM-033 were performed similarly. They took place in the same room and used the same tanks, some of the same moderators and absorbers, some of the same reflector panels, and uranyl nitrate solution from the same location. There are probably additional similarities that existed that are not identified here. Thus, many of the descriptions in this report are either the same or similar to those in the HEU-SOL-THERM-033 report. Seventeen configurations (sixteen of which were critical) were performed during seven experiments; six of those experiments are evaluated here with thirteen configurations. Two configurations were identical, except for solution height, and were conducted to test repeatability. The solution heights were averaged and the two were evaluated as one configuration, which gives a total of twelve evaluated configurations. One of the seventeen configurations was subcritical. Of the twelve critical configurations evaluated, nine were judged as acceptable as benchmarks.

Development of the first nonhydrostatic nested-grid grid-point global atmospheric modeling system on parallel machines  

SciTech Connect

This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Evaluating the importance of global and regional climate response to increasing atmospheric concentrations of greenhouse gases requires a comprehensive global atmospheric modeling system (GAMS) capable of simulations over a wide range of atmospheric circulations, from complex terrain to continental scales, on high-performance computers. Unfortunately, all of the existing global circulation models (GCMs) do not meet this requirements, because they suffer from one or more of the following three shortcomings: (1) use of the hydrostatic approximation, which makes the models potentially ill-posed; (2) lack of a nested-grid (or multi-grid) capability, which makes it difficult to consistently evaluate the regional climate response to the global warming, and (3) spherical spectral (opposed to grid-point finite-difference) representation of model variables, which hinders model performance for parallel machine applications. The end product of the research is a highly modularized, multi-gridded, self-calibratable (for further parameterization development) global modeling system with state-of-the-science physics and chemistry. This system will be suitable for a suite of atmospheric problems: from local circulations to climate, from thunderstorms to global cloud radiative forcing, from urban pollution to global greenhouse trace gases, and from the guiding of field experiments to coupling with ocean models.

Nested Domain Defects  

E-Print Network (OSTI)

An example of a supersymmetric model involving two interacting chiral superfields is presented here which allows for solutions describing string-like ``domain ribbon'' defects embedded within a domain wall. It is energetically favorable for the fermions within the wall to populate the domain ribbons, and an explicit solution is found for the fermion zero modes. The Fermi gas within ribbons can allow them to stabilize in the form of small loops.

Simulations of present and future climates in the western U.S. with four nested regional climate models  

SciTech Connect

We analyze simulations of present and future climates in the western U.S. performed with four regional climate models (RCMs) nested within two global ocean-atmosphere climate models. Our primary goal is to assess the range of regional climate responses to increased greenhouse gases in available RCM simulations. The four RCMs used different geographical domains, different increased greenhouse gas scenarios for future-climate simulations, and (in some cases) different lateral boundary conditions. For simulations of the present climate, we compare RCM results to observations and to results of the GCM that provided lateral boundary conditions to the RCM. For future-climate (increased greenhouse gas) simulations, we compare RCM results to each other and to results of the driving GCMs. When results are spatially averaged over the western U.S., we find that the results of each RCM closely follow those of the driving GCM in the same region, in both present and future climates. In present-climate simulations, the RCMs have biases in spatially-averaged simulated precipitation and near-surface temperature that seem to be very close to those of the driving GCMs. In future-climate simulations, the spatially-averaged RCM-projected responses in precipitation and near-surface temperature are also very close to those of the respective driving GCMs. Precipitation responses predicted by the RCMs are in many regions not statistically significant compared to interannual variability. Where the predicted precipitation responses are statistically significant, they are positive. The models agree that near-surface temperatures will increase, but do not agree on the spatial pattern of this increase. The four RCMs produce very different estimates of water content of snow in the present climate, and of the change in this water content in response to increased greenhouse gases.

Independence and interdependence in the nest-site choice by honeybee swarms: agent-based models, analytical approaches and pattern formation  

E-Print Network (OSTI)

In a recent paper List, Elsholtz and Seeley [Phil. Trans. Roy. Soc. B. 364 (2009) 755] have devised an agent-based model of the the nest-choice dynamics in swarms of honeybees, and have concluded that both interdependence and independence are needed for the bees to reach a consensus on the best nest site. We here present a simplified version of the model which can be treated analytically with the tools of statistical physics and which largely has the same features as the original dynamics. Based on our analytical approaches it is possible to characterize the co-ordination outcome exactly on the deterministic level, and to a good approximation if stochastic effects are taken into account, reducing the need for computer simulations on the agent-based level. In the second part of the paper we present a spatial extension, and show that transient non-trivial patterns emerge, before consensus is reached. Approaches in terms of Langevin equations for continuous field variables are discussed.

Future Potential of Hybrid and Diesel Powertrains in the U.S. Light-duty Vehicle Market  

Science Conference Proceedings (OSTI)

Diesel and hybrid technologies each have the potential to increase light-duty vehicle fuel economy by a third or more without loss of performance, yet these technologies have typically been excluded from technical assessments of fuel economy potential on the grounds that hybrids are too expensive and diesels cannot meet Tier 2 emissions standards. Recently, hybrid costs have come down and the few hybrid makes available are selling well. Diesels have made great strides in reducing particulate and nitrogen oxide emissions, and are likely though not certain to meet future standards. In light of these developments, this study takes a detailed look at the market potential of these two powertrain technologies and their possible impacts on light-duty vehicle fuel economy. A nested multinomial logit model of vehicle choice was calibrated to 2002 model year sales of 930 makes, models and engine-transmission configurations. Based on an assessment of the status and outlook for the two technologies, market shares were predicted for 2008, 2012 and beyond, assuming no additional increase in fuel economy standards or other new policy initiatives. Current tax incentives for hybrids are assumed to be phased out by 2008. Given announced and likely introductions by 2008, hybrids could capture 4-7% and diesels 2-4% of the light-duty market. Based on our best guesses for further introductions, these shares could increase to 10-15% for hybrids and 4-7% for diesels by 2012. The resulting impacts on fleet average fuel economy would be about +2% in 2008 and +4% in 2012. If diesels and hybrids were widely available across vehicle classes, makes, and models, they could capture 40% or more of the light-duty vehicle market.

Synthesis and Comparison of Baseline Avian and Bat Use, Raptor Nesting and Mortality Information from Proposed and Existing Wind Developments: Final Report.  

DOE Green Energy (OSTI)

Primarily due to concerns generated from observed raptor mortality at the Altamont Pass (CA) wind plant, one of the first commercial electricity generating wind plants in the U.S., new proposed wind projects both within and outside of California have received a great deal of scrutiny and environmental review. A large amount of baseline and operational monitoring data have been collected at proposed and existing U.S. wind plants. The primary use of the avian baseline data collected at wind developments has been to estimate the overall project impacts (e.g., very low, low, moderate, and high relative mortality) on birds, especially raptors and sensitive species (e.g., state and federally listed species). In a few cases, these data have also been used for guiding placement of turbines within a project boundary. This new information has strengthened our ability to accurately predict and mitigate impacts from new projects. This report should assist various stakeholders in the interpretation and use of this large information source in evaluating new projects. This report also suggests that the level of baseline data (e.g., avian use data) required to adequately assess expected impacts of some projects may be reduced. This report provides an evaluation of the ability to predict direct impacts on avian resources (primarily raptors and waterfowl/waterbirds) using less than an entire year of baseline avian use data (one season, two seasons, etc.). This evaluation is important because pre-construction wildlife surveys can be one of the most time-consuming aspects of permitting wind power projects. For baseline data, this study focuses primarily on standardized avian use data usually collected using point count survey methodology and raptor nest survey data. In addition to avian use and raptor nest survey data, other baseline data is usually collected at a proposed project to further quantify potential impacts. These surveys often include vegetation mapping and state or federal sensitive-status wildlife and plant surveys if there is a likelihood of these species occurring in the vicinity of the project area. This report does not address these types of surveys, however, it is assumed in this document that those surveys are conducted when appropriate to help further quantify potential impacts. The amount and extent of ecological baseline data to collect at a wind project should be determined on a case-by-case basis. The decision should use information gained from this report, recent information from new projects (e.g., Stateline OR/WA), existing project site data from agencies and other knowledgeable groups/individuals, public scoping, and results of vegetation and habitat mapping. Other factors that should also be considered include the likelihood of the presence of sensitive species at the site and expected impacts to those species, project size and project layout.

The image created in reflected light DIC can often be interpreted as a true three-dimensional representation of the surface geometry, provided a clear distinction can be realized between raised and lowered regions in the specimen. It may be helpful if our definition of saliency embraces work on the human visual system (HVS) as well as the more abstract work on saliency, as it is certain that understanding by humans will always stand between recording of a useful signal from all manner of sensors and so-called actionable intelligence. A DARPA/DSO program lays down this requirement in a current program (Kruse 2010): The vision for the Neurotechnology for Intelligence Analysts (NIA) Program is to revolutionize the way that analysts handle intelligence imagery, increasing both the throughput of imagery to the analyst and overall accuracy of the assessments. Current computer-based target detection capabilities cannot process vast volumes of imagery with the speed, flexibility, and precision of the human visual system.

Examining solid waste management issues in the City of Bryan  

E-Print Network (OSTI)

Economic aspects of household recycling behavior and attitudes in City of Bryan are examined to improve solid waste management policies in the city. Using survey data collected by mail and personal interviews, residentsÂ? attitudes towards solid waste management are analyzed, in general, and specifically, the factors influencing recycling behavior examined using logistic regression. In addition, three alternative policies are presented to respondents. First, support for an additional drop-off recycling center (Policy I) is examined. Second, WTP for two different recycling programs, curbside recycling service (Policy II), and curbside recycling with a drop-off recycling center (Policy III), as a function of socio-economic factors thought to influence WTP are computed using contingent valuation method, an indirect valuation tool. Finally, preference for a particular policy among the three alternatives presented to the residents of Bryan is explored. Because of the different data collection modes and assumptions on the bid prices two logit models are estimated to examine recycling behavior, and Policy I and two multinomial logit models for the most preferred policy, whereas four logit models are estimated for Policy II and III. The estimated models are similar both within the Policies and between the Policies in terms of the affects of variables, significance of coefficients, and consistency with previous studies indicating a potential set of factors that can be used to explain WTP for recycling services. Bryan residents that are female, white, employed, have higher incomes, have children, own a house, and are self-perceived environmentalists tend to recycle more. Similarly, males, nonwhites, older respondents, students, non-environmentalists and non-recyclers are more likely to support an additional drop-off center. WTP for Policy II is positively influenced by males, whites, respondents who are employed, low-income respondents, environmentalists, non-recyclers, and those who support Policy I. In comparison, WTP for Policy III is positively influenced by females, whites, respondents who are employed, younger respondents, environmentalists, non-recyclers, and those who support Policy I. In the case of both Policies I and II, the bid price negatively influences WTP as expected. While the WTP for Policy II is slightly higher than the estimated cost of a curbside recycling service ($2.50), the WTP for Policy III is lower than the estimated cost. No consistent pattern emerges across most of the coefficients and the four possible alternatives, three proposed policies and the current situation. However, probabilities computed using the multinomial logit results is the highest for Policy II, followed by either Policy III or no change to the existing solid waste management policy.

Does Homeownership Lengthen Unemployment Duration? A French Micro-econometric Study  

E-Print Network (OSTI)

The objective of this paper is to provide microeconomic evidence for the so called “Oswald’s hypothesis”, which is whether homeownership results in negative outcomes in the labour market. In a first step, a multinomial logit model for the choice of tenure status is estimated. Estimated probabilities of being either homeowner, renter or housed free of charge are then used to explain the length of an individual unemployment spell. This flexible method of estimation accounts for both censoring and selection bias, without constraining the shape of the hazard rate of leaving unemployment. Results from a 3,965 individuals French data set suggest that home-ownership has a positive effect on unemployment duration.

Modeling the residential demand for energy  

Science Conference Proceedings (OSTI)

Demand for energy is derived from the demand for services that appliances and energy together provide. This raises a number of serious econometric issues when estimating energy-demand functions: delineation of short-run and long-run household responses, specification of the price variable and in particular, the assumption that the model is recursive, or in other words, that the appliance choice equation and the energy consumption equation are uncorrelated. The dissertation utilizes a structural model of energy use whose theoretical underpinnings derive from the conditional logit model and an extension of that model to the joint-discrete/continuous case by Dubin and McFadden (1980). It uses the 1978 to 1979 National Interim Energy Comsumption Survey. Three appliance portfolio choices are analyzed; choice of water and space heating and central air-conditioning; choice of room air conditioners; and choice of clothes dryers, either as multinomial logit or binary probit choices. Results varied widely across the appliance choice considered; use of Hausman's test led to acceptance of the null hypothesis of orthogonality in some cases but not in others. Demand for electricity and natural gas tended to be price inelastic; however, estimated own-price effects differed considerably when disaggregated by appliance categories and across methods of estimation.

Regional Incentives and Industrial Location in Puerto Rico  

E-Print Network (OSTI)

This study uses nested logit to estimate the influence of industrial incentives on the location of manufacturing plants in Puerto Rico. Puerto Rican laws grant generous tax exemptions and provide other incentives for investments in less-developed, peripheral regions of the island. Focusing on Puerto Rico allowed us to isolate and test location factors in a closed environment where 76 municipalities received a development zone designation and competed directly against one another for new plants. Simulations indicated that the regional incentive policy reallocated relatively few of the greenfield investments from the congested core to the periphery of the island.

Diet of Nesting Red-Cockaded Woodpecker at Three Locations  

DOE Green Energy (OSTI)

The authors studied diets of nestling red-cockaded woodpeckers for two years on three sites in South Carolina and Georgia. Cameras recorded 33 different types of prey. Wood roaches were the most common, amounting to 50% of the prey. In addition, blueberries and saw fly larvae were collected by birds. Snail shells were also collected. Morista's index of diet overlap ranged from 0.94 to 0.99 for breeding males and females. We conclude that nestling diets are similar across the region.

A REVIEW OF ASSUMPTIONS AND ANALYSIS IN EPRI EA-3409,"HOUSEHOLD APPLIANCE CHOICE: REVISION OF REEPS BEHAVIORAL MODELS"  

SciTech Connect

This paper revises and extends EPRI report EA-3409, ''Household Appliance Choice: Revision of REEPS Behavioral Models.'' That paper reported the results of an econometric study of major appliance choice in new residential construction. Errors appeared in two tables of that report. We offer revised versions of those tables, and a brief analysis of the consequences and significance of the errors. The present paper also proposes several possible extensions and re-specifications of the models examined by EPRI. Some of these are judged to be highly successful; they both satisfy economic intuition more completely than the original specification and produce a better quality fit to the dependent variable. We feel that inclusion of these modifications produces a more useful set of coefficients for economic modeling than the original specification. This paper focuses on EPRI's models of residential space heating technology choice. That choice was modeled as a nested logit structure, with consumers choosing whether to have central air conditioning or not, and, given that choice, what kind of space heating system to have. The model included five space heating alternatives with central cooling (gas, oil, and electric forced-air; heat pumps; and electric baseboard) and eight alternatives without it (gas, oil, and electric forced-air; gas and oil boilers and non-central systems; and electric baseboard heat). The structure of the nested logit model is shown in Figure 1.

Household waste disposal in Mekelle city, Northern Ethiopia  

SciTech Connect

In many cities of developing countries, such as Mekelle (Ethiopia), waste management is poor and solid wastes are dumped along roadsides and into open areas, endangering health and attracting vermin. The effects of demographic factors, economic and social status, waste and environmental attributes on household solid waste disposal are investigated using data from household survey. Household level data are then analyzed using multinomial logit estimation to determine the factors that affect household waste disposal decision making. Results show that demographic features such as age, education and household size have an insignificant impact over the choice of alternative waste disposal means, whereas the supply of waste facilities significantly affects waste disposal choice. Inadequate supply of waste containers and longer distance to these containers increase the probability of waste dumping in open areas and roadsides relative to the use of communal containers. Higher household income decreases the probability of using open areas and roadsides as waste destinations relative to communal containers. Measures to make the process of waste disposal less costly and ensuring well functioning institutional waste management would improve proper waste disposal.

Analysis of Whole Milk vs. Low-Fat Milk Consumption Among WIC Children Before Programmatic Changes  

E-Print Network (OSTI)

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is one of the food assistance programs targeted at low-income women, infants and children up to age five by providing foods, nutrition education and other services. Recent updates in food packages provided by WIC include the addition of fruits, vegetables and whole wheat products as well as the removal of whole milk for women and children two years and older. This thesis concentrates on preschool children participants in the WIC program and their milk consumption habits prior to programmatic changes. Analyzing diet preferences of these children is crucial since a quarter of the population of children aged one thorough five participates in the WIC program; as well, they are not eligible to receive whole milk with WIC food packages after the implementation of revisions. The objective is to describe the profile of preschool WIC children and their milk consumption attributes based on the National Food and Nutrition (NATFAN) questionnaire designed and conducted by the Institute for Obesity Research and Program Evaluation at Texas A & M University before the release of the revised WIC food packages. Additionally, findings of the study are compared with the National Health and Nutrition Examination Survey (NHANES) 2005-2006 dataset results. Milk consumption preferences of WIC children are analyzed nationwide and impacts of race, ethnicity, regional, and other demographic characteristics are observed. Using both NATFAN and NHANES datasets provides a comparison of actual and self-reported participation outcomes. Discrete choice models were used in this analysis, in particular binary logit and multinomial logit models. The results of the thesis indicate that WIC preschool children mostly drink whole milk (36.17 percent) and 2 percent fat milk (49.94 percent). Two year old participants, children located in the South and participants whose caregivers are younger and less educated are more likely to consume whole milk. Caucasian children are less likely to choose whole milk and more likely to choose reduced fat milk; African Americans are more likely to select whole milk. Furthermore, diet preferences and knowledge of parents/caregivers play a major role on milk consumption of children. Children whose caregivers are willing to give low-fat milk to children aged two to five are less likely to drink whole milk.

Nested Fixed Depth Fluidic Sampler and At Tank Analysis System Deployment Strategy and Plan  

Science Conference Proceedings (OSTI)

Under the Hanford Site River Protection Project (RPP) privatization strategy, the U.S. Department of Energy (DOE) Office of River Protection (ORP) requires the CH2M Hill Hanford Group, Inc. (CHG) to supply tank waste to the privatization contractor, BNFL Inc. (BNFL), for separation and/or treatment and immobilization (vitrification). Three low-activity waste (LAW) specification envelopes represent the range of liquid waste types in the large, Hanford Site underground waste storage tanks. The CHG also is expected to supply high-level waste (HLW) separation and/or treatment and disposal. The HLW envelope is an aqueous slurry of insoluble suspended solids (sludge). The Phase 1 demonstration will extend over 24 years (1996 through 2019) and will be used to resolve technical uncertainties. About one-tenth of the total Hanford Site tank waste, by mass, will be processed during this period. This document provides a strategy and top-level implementation plan for demonstrating and deploying an alternative sampling technology. The alternative technology is an improvement to the current grab sampling and core sampling approaches that are planned to be used to support the RPP privatization contract. This work also includes adding the capability for some at-tank analysis to enhance the potential of this new technology to meet CHG needs. The first application is to LAW and HLW feed staging for privatization; the next is to support cross-site waste transfer from 200 West Area tanks.

Spatial Analysis of Residential Development and Urban-Rural Zoning in Baltimore County, Maryland  

E-Print Network (OSTI)

Over the past half-century, Baltimore County, Maryland has experienced various policy measures that have shaped development patterns. This thesis analyzes three spatially explicit parcel-level models of residential development in Baltimore County to examine the effects of land-use regulations on multiple density classes from 1996 to 2008. The first model analyzes the entire county, while the second analyzes areas outside the county urban growth boundary, while the third model studied areas inside the boundary. While this region has been previously analyzed, prior studies have generally ignored policy affects upon the density of new residential subdivisions. The use of a binary dependent variable, i.e. develop or not develop, represents a critical oversight as this assumes policy measures exert a uniform impact across all development types. This study addressed this issue with the literature by using a multinomial logit model to differentiate the effects of various development policies to better understand residential growth. The objective of this research is to determine what factors influence individual landowner's decision to convert an undeveloped property to residential use. The impacts of rural conservation (RC) zoning and urban growth boundaries (UGB) comprise the prominent land-use regulations analyzed in this study. The empirical estimates provided significant evidence that maximum density zoning effectively limits the density of new residential development in almost every model. Other policy measures, mainly rural legacy areas and critical areas, were generally found to be ineffective at limiting growth. This research concludes that maximum density zoning comprises the strongest tool for limiting development to a density mandated by the county government. Finally, maps depicting the predicted probability of development at two densities are included and discussed to indicate the areas most likely to be subdivided for residential land use.

Administration Written by Billie HardinExecutive Summary  

E-Print Network (OSTI)

(KCTCS) has excelled in many areas of its open enrollment or open access mission. Yet, many KCTCS students do not persist to graduate with a credential or transfer to a 4-year postsecondary institution. The Kentucky Council on Postsecondary Education (CPE), reports that of the fall 2001 students who entered KCTCS colleges, only 50.2 percent earned a degree, transferred to a 4-year college or university, or were still enrolled in a KCTCS college within three years. CPE further reports that more than half of Kentucky’s 2004 entering postsecondary freshmen were underprepared in at least one subject. The majority of these students enrolled in one of 16 colleges comprising KCTCS. When all KCTCS firsttime, 2004 credential seeking freshmen are included (such as adult learners), 82 percent of students entering KCTCS colleges required developmental education at an estimated cost of more than $15.6 million. It is estimated that Kentucky’s General Fund costs for remediation instruction during the 2004-05 academic year totaled over $13.2 million dollars. Research Strategy Using a multinomial logit analysis, the paper focuses on identifying statistically significant variables that affect the conditional probability of KCTCS students succeeding. The study sample includes 10,007 first-time KCTCS students entering fall 2001 and examines the affect that 13 predictor variables have on the odds of KCTCS students achieving one of four success outcomes relative to not achieving success. Defining success as credential attainment (earning an associate degree, certificate, or diploma) or transfer to a 4-year institution, the following questions guide the research: ? Does a student’s ACT score increase the likelihood of success? ? Is a student’s first semester GPA a significant predictor of student success? How likely are nontraditional students to succeed? Are students who are offered Pell Grants less likely to succeed than students who do not receive such aid?

Second Malignant Neoplasms in Digestive Organs After Childhood Cancer: A Cohort-Nested Case-Control Study  

SciTech Connect

Purpose: Cancers of the digestive system constitute a major risk for childhood cancer survivors treated with radiotherapy once they reach adulthood. The aim of this study was to determine therapy-related risk factors for the development of a second malignancy in the digestive organs (SMDO) after a childhood cancer. Methods and Materials: Among 4,568 2-year survivors of a childhood solid cancer diagnosed before 17 years of age at eight French and British centers, and among 25,120 patients diagnosed as having a malignant neoplasm before the age of 20 years, whose data were extracted from the Nordic Cancer Registries, we matched 58 case patients (41 men and 17 women) of SMDO and 167 controls, in their respective cohort, for sex, age at first cancer, calendar year of occurrence of the first cancer, and duration of follow-up. The radiation dose received at the site of each second malignancy and at the corresponding site of its matched control was estimated. Results: The risk of developing a SMDO was 9.7-fold higher in relation to the general populations in France and the United Kingdom. In the case-control study, a strong dose-response relationship was estimated, compared with that in survivors who had not received radiotherapy; the odds ratio was 5.2 (95% CI, 1.7-16.0) for local radiation doses between 10 and 29 Gy and 9.6 (95% CI, 2.6-35.2) for doses equal to or greater than 30 Gy. Chemotherapy was also found to increase the risk of developing SMDO. Conclusions: This study confirms that childhood cancer treatments strongly increase the risk of SMDO, which occur only after a very long latency period.

Home-based work, human capital accumulation and women's labor force participation  

E-Print Network (OSTI)

This dissertation examines the effect of changes in the stock of human capital on the labor force participation decision of women aged 25-54. Without the option of homebased work, some women choose to leave the labor market and stay at home temporarily for family reasons. Working women realize that time out of the labor force could impose penalties on their work careers. This is because during the break, they do not accumulate any new human capital while the existing job skills continuously depreciate. Nowadays, home-based work becomes possible for many jobs because rapid development in personal computers and advances in information and communications technology have reduced employers� cost of offering home-based work arrangements. Working women can resolve the time conflict between demand for paid work and family responsibility by working from home. In a previous study, the home-based work decision depends on the fixed cost of working and potential home production. Women who are disabled, have small children, or live in rural areas are likely to work from home because they have high fixed costs of working and high potential home production. However, none of the existing studies applies the human capital theory of labor supply to the home-based work decision. Using data on the female labor force from the Integrated Public Use Microdata Series (IPUMS) of housing units from the 2000 U.S. Census, I estimate a nested logit model to examine the effects of expected costs of non-participation, in terms of forgone earnings, forgone human capital accumulation and human capital depreciation, on women�s labor force participation decision. I find that, other things being equal, women aged 25 to 44 who have potentially high human capital accumulation and high human capital depreciation are likely to stay in the labor force. In the case that the value of their home time is so high that they choose to stay at home, they prefer to work for pay at home than to be out of the labor force.

Numeric Definition of the Clinical Performance of the Nested Reverse Transcription-PCR for Detection of Hematogenous Epithelial Cells and Correction for Specific mRNA of Non-Target Cell Origin as Evaluated for Prostate Cancer Cells  

E-Print Network (OSTI)

Background: Inappropriate quality management of reverse transcription-PCR (RT-PCR) assays for the detection of blood-borne prostate cancer (PCa) cells hampers clinical conclusions. Improvement of the RT-PCR methodology for prostate-specific antigen (PSA) mRNA should focus on an appropriate numeric definition of the performance of the assay and correction for PSA mRNA that is not associated with PCa cells. Methods and Results: Repeated (RT-)PCR tests for PSA mRNA in single blood specimens from PCa patients and PCa-free controls, performed by four international institutions, showed a large percentage (?50%) of divergent test results. The best estimates of the mean, ? (SD), of the expected Poisson frequency distributions of the number of positive tests among five replicate assays of

DOE Green Energy (OSTI)

Natural resource professionals are increasingly required to develop rigorous statistical models that relate environmental data to categorical responses data. Recent advances in the statistical and computing sciences have led to the development of sophisticated methods for parametric and nonparametric analysis of data with categorical responses. The statistical software package CATDAT was designed to make some of these relatively new and powerful techniques available to scientists. The CATDAT statistical package includes 4 analytical techniques: generalized logit modeling; binary classification tree; extended K-nearest neighbor classification; and modular neural network.

Analyzing Data for Systems Biology: Working at the Intersection of Thermodynamics and Data Analytics  

Science Conference Proceedings (OSTI)

Many challenges in systems biology have to do with analyzing data within the framework of molecular phenomena and cellular pathways. How does this relate to thermodynamics that we know govern the behavior of molecules? Making progress in relating data analysis to thermodynamics is essential in systems biology if we are to build predictive models that enable the field of synthetic biology. This report discusses work at the crossroads of thermodynamics and data analysis, and demonstrates that statistical mechanical free energy is a multinomial log likelihood. Applications to systems biology are presented.

Impacts of Water Levels on Breeding Canada Geese and the Methodology for Mitigation and Enhancement in the Flathead Drainage, 1985-1986 Annual Report.  

DOE Green Energy (OSTI)

The lower Flathead System Canada Goose Study was initiated to determine population trends and the effects of water level fluctuations on nest and brood habitat on the southern half of Flathead Lake and the lower Flathead River as a result of the operations of Kerr Dam. This report presents data collected during the 1985 field season. Goose use patterns were similar to those observed in 1984. From late summer through fall use of the river was low and use of the reservoirs was high. Use of the river increased as reservoirs began to freeze and by mid-December most geese were using the river. The lower half of the river froze in late January and most geese apparently left the valley. Use of the river increased during the nesting period and remained relatively stable through the brooding period. The indicated pairs/nest ratio was 1.2 for the entire river and 1.5 for the southern half of the river. Fifty percent (26 of 52) of the tree nest structures on the river were used by geese in 1985. Overall nesting success of geese using nest structures was 84%. Seventy-one nests were located on the river in 1985. The total number of nests found on the nesting islands of Flathead Lake was 166 during 1985. A riparian community type classification is currently being developed and will be used next year to map the study area. Nest and random sites as well as general island characteristics were investigated and comparisons were made between areas used and areas available to nesting geese. Activity budget analyses indicated that the two primary activities of goslings were feeding and resting while alert and feeding were the two primary activities of adults. Herbaceous habitats were used by broods more than any other type and were important for all activities.

Estimation of binary Markov random fields  

E-Print Network (OSTI)

The theoryand practiceof estimationof binary Markov random fields on lattices is reviewedand advanced. The natural objects of inference are the local conditionaldistributions, which define an exponential family owing to the equivalence between Markov and Gibbs random fields. Maximumlikelihoodestimation generally is impracticable. Methods of asymptotic, or otherwise approximate, maximum likelihood estimation do not easily apply in all cases likely to be of practical interest. The only generallypracticableprocedures available thus far are the Coding Method and MaximumPseudo-Likelihood. A new estimation procedure is suggestedthat is strongly consistentfor processesdefined by translation-invariant families of local conditionaldistributions. The procedure is analogous to minimum logit chi-squareestimation in logistic regression, does not involve non-linearoptimization, and decisively beats Maximum Pseudo-Likelihood in mean squarederror. Subsarnpling techniques can be employed to assess precision,and to increase efficiency, in estimation.

Department of Agricultural and Resource EconomicsDetermining the Impact of Retailer Store Brand Procurement on Vertical Relationships with Brand Manufacturers and on Market Equilibrium †  

E-Print Network (OSTI)

This paper investigates how a retailer’s store brand supply source impacts vertical pricing and supply channel profitability. Using chain-level retail scanner data from major supermarkets in Boston prior to the leading retailer’s divestiture of its store brand milk processing to a major brand manufacturer I estimate a random coefficients logit demand model employing a Bayesian estimation approach. Bayesian decision theory is applied to select from a set of pricing games the one most likely for the data sample analyzed. Results from this analysis indicate that the empirically valid model has the pre-divested retailer integrated into the processing of its own milk and takes as given the wholesale price of brand milks while competing retailers have nonlinear pricing contracts with brand manufacturers who produce their store brands. This model is matched against a series of counterfactual simulations as a baseline. The counterfactual simulations consider the eventual divestiture of store brand milk processing by the leading retailer

MODELING THE DEMAND FOR E85 IN THE UNITED STATES  

SciTech Connect

How demand for E85 might evolve in the future in response to changing economics and policies is an important subject to include in the National Energy Modeling System (NEMS). This report summarizes a study to develop an E85 choice model for NEMS. Using the most recent data from the states of Minnesota, North Dakota, and Iowa, this study estimates a logit model that represents E85 choice as a function of prices of E10 and E85, as well as fuel availability of E85 relative to gasoline. Using more recent data than previous studies allows a better estimation of non-fleet demand and indicates that the price elasticity of E85 choice appears to be higher than previously estimated. Based on the results of the econometric analysis, a model for projecting E85 demand at the regional level is specified. In testing, the model produced plausible predictions of US E85 demand to 2040.

Estimating disaggregated price elasticities in industrial energy demand  

Science Conference Proceedings (OSTI)

Econometric energy models are used to evaluate past policy experiences, assess the impact of future policies and forecast energy demand. This paper estimates an industrial energy demand model for the province of Ontario using a linear-logit specification for fuel type equations which are embedded in an aggregate energy demand equation. Short-term, long-term, own- and cross-price elasticities are estimated for electricity, natural gas, oil and coal. Own- and cross-price elasticities are disaggregated to show that overall price elasticities and the energy-constant price elasticities when aggregate energy use is held unchanged. These disaggregations suggest that a substantial part of energy conservation comes from the higher aggregate price of energy and not from interfuel substitution. 13 refs., 2 tabs.

Bayesian inference through encompassing priors and importance sampling for a class of marginal models for categorical data  

E-Print Network (OSTI)

We develop a Bayesian approach for selecting the model which is the most supported by the data within a class of marginal models for categorical variables formulated through equality and/or inequality constraints on generalised logits (local, global, continuation or reverse continuation), generalised log-odds ratios and similar higher-order interactions. For each constrained model, the prior distribution of the model parameters is formulated following the encompassing prior approach. Then, model selection is performed by using Bayes factors which are estimated by an importance sampling method. The approach is illustrated through three applications involving some datasets, which also include explanatory variables. In connection with one of these examples, a sensitivity analysis to the prior specification is also considered.

Effects of Water Levels on Productivity of Canada Geese in the Northern Flathead Valley, Final Report.  

DOE Green Energy (OSTI)

The Fish and Wildlife Program of the Northwest Power Planning Council calls for wildlife mitigation at hydroelectric projects in the Columbia River System. Beginning April, 1984, the Bonneville Power Administration funded a study of the effects of the operation of Hungry Horse and Kerr Dams on the western Canada goose (Branta canadensis moffittii) inhabitating the Flathead Valley of northwest Montana. The study was conducted by personnel of the Montana Department of Fish, Wildlife and Parks (MDFWP), to: (1) identify the size and productivity of this population, (2) identify current habitat conditions and losses of nesting and brood-rearing areas, (3) describe the effects of water level fluctuations on nesting and brood-rearing, and (4) identify mitigation alternatives to offset these effects. Annual pair and nest surveys were used to document the location and fate of goose nests. The number of known nesting attempts varied from 44 in 1984 to 108 in 1985, to 136 in 1986 and 134 in 1987. Fifty-four percent of the annual meeting nesting effort took place on elevated sites which were secure from the flooding and dewatering effects of fluctuating water levels. An average of 15 nests were found on stumps in the remnant Flathead River delta, however, an area strongly influenced by the operation of Kerr Dam. Annual nest losses to flooding and predation attributable to fluctuations caused by the dam were recorded. 53 refs., 24 figs., 35 tabs.

Impacts of Water Levels on Breeding Canada Geese and Methods for Mitigation and Management in the Southern Flathead Valley, Montana, 1983-1987 Final Report.  

DOE Green Energy (OSTI)

Kerr Hydroelectric Dam is located at the south end of Flathead Lake, controls water levels on the lake and the Flathead River below the dam, and is currently operated as a load control facility. Current operation of Kerr Dam creates the greatest yearly water level fluctuations on both the lake and river during the Canada goose (Branta canadensis moffitti) brood and nesting period. Data collected from 1980-1982 indicated that goose nest numbers on the river were lower than during the 1950's, and that brood habitat on the lake may be limiting the goose population there. Our study was conducted from 1983-1987 to determine the effects of Kerr Dam operation on Canada goose populations and habitat on the south half of Flathead Lake and the Flathead River, and to formulate management and mitigation recommendations. Nesting geese on the river appeared to be negatively affected by a lack of nest sites free from predators, and responded to available artificial nest structures with an increase in nest numbers and nesting success. Under current dam operation, river channel depths and widths do not discourage access to nesting islands by mammalian predators during some years and high predation on ground nests occurs. Intensively used brood areas on the lake and river were identified and described. Brood habitat on the lake was lower in quality and quantity than on the river due to dam operations. Gosling mortality on the lake was high, almost 2 times higher than on the river. Lake broods expended more energy obtaining food than river broods. Losses of brood habitat in the form of wet meadow marshes were documented and mitigation options developed. Management/mitigation alternatives and monitoring methods for nesting and brooding geese were identified.

Smoking, Drinking, and Income  

E-Print Network (OSTI)

A growing literature identifies a beneficial effect of moderate and even heavy drinking on wages and a negative effect of smoking on wages. An outstanding issue is whether these results obtain because of a causal effect of substance use on wages or whether the observed correlations reflect the effects of income on consumption or other endogeneity problems. This paper presents full information estimates of the structural parameters of a simultaneous model of drinking and smoking status and income using repeated cross--section data. With all else in the system held constant, both smoking and drinking behaviour still have large effects on income, and the income elasticities of smoking and drinking are shown to be larger in magnitude when controlling for endogeneity.

Reproductive success of oak woodland birds in Sonoma and Napa counties. In  

E-Print Network (OSTI)

Birds are often used as environmental indicators because they are conspicuous, they have a very broad constituency, respond to change at multiple spatial scales, and are sampled by standard protocols. However simple counts of birds may provide an incomplete picture of the response of bird populations to environmental change in rapidly changing landscapes like California’s oak woodlands. Demographic data such as reproductive success provide a better measure of habitat quality and response to landscape modification. We collected reproductive success information on 398 nests of 38 species of birds nesting in oak woodlands of Sonoma and Napa counties in 2003 and 2004. We found no evidence that the extent of vineyard at the landscape-level had negative effects on the number of nests, frequency of nests per nest type, nor nest success. In fact, high vineyard-influence sites had slightly higher nest success. Our results suggest that remaining oak woodlands in vineyard landscapes, if properly managed and of sufficient size, can still support a diverse and productive avifauna.

USER 2.1; User Specified Estimation Routine, Techncial Manual 2003.  

DOE Green Energy (OSTI)

This document is primarily a description of the user interface for USER2.1; it is not a description of the statistical theory and calculations behind USER. This project is funded by the Bonneville Power Administration, U.S. Department of Energy, under Contract No. 004126, Project No. 198910700 as part of the BPA's program to protect, mitigate, and enhance fish and wildlife affected by the development and operation of hydroelectric facilities on the Columbia River and its tributaries. The analysis of fish and wildlife data requires investigators to have the ability to develop statistical models tailored to their study requirements. Hence, a flexible platform to develop statistical likelihood models to estimate demographic parameters is necessary. To this end, Program USER (User Specified Estimation Routine) was developed to provide a convenient platform for investigators to develop statistical models and analyze tagging and count data. The program is capable of developing models and analyzing any count data that can be described by multinomial or product multinomial distributions. Such data include release-recapture studies using PIT-tags, radio-tags, balloon-tags, and acoustic-tags to estimate survival, movement, and demographic data on the age and/or sex structure of wild populations. The user of the program can specify the parameters and model structure at will to tailor the analyses to the specific requirements of the field sampling program, the data, and populations under investigation. All of this is available without the need for the user to know advanced programming languages or numerical analysis techniques, and without involving cumbersome software developed for extraneous purposes. Program USER represents a powerful statistical modeling routine that can be readily used by investigators with a wide range of interests and quantitative skills.

The Determinants of Homeonwership in Presence of Shocks Experienced by Mexican Households  

E-Print Network (OSTI)

Homeownership is both an individual and society objective, because of the positive neighborhood effects associated with areas of higher homeownership. To help realize these positive effects, the Mexican government has several programs directed to increasing homeownership. Many factors, however, may influence homeownership including shocks experienced by households. Shocks such as death in family, illness or accidents, unemployment, and business, crop, or livestock loss affect homeownership if households are unable to cushion the impact of the shock. Government income support programs, however, may help cushion the effect of a shock. The main objective is to determine how shocks that households’ experience and government income support programs influence homeownership in Mexico. A secondary objective is to determine how socio-demographic variables influence homeownership in Mexico. Based on the Random Utility Model, logit models of homeownership are estimated using data are from the 2002 Mexican National Survey on Living Levels of Households. Two models are estimated; with and without income. Income is excluded because of a large number of households that did not report income. Generally, inferences from the two models are similar. Homeownership appears to not be affected by shocks experienced by households. It appears households are able to cushion the impact of shocks. The two income support programs, the Program of Direct Rural Support of Mexico (PROGRESA) and the Program of Direct Rural Support of Mexico (PROCAMPO), appear to be increasing homeownership. These social welfare programs provide cash transfers to households. For whatever reason, PROGRESA has a larger effect on homeownership than PROCAMPO. Households with older heads have a larger probability of being a homeowner than households with younger heads. No statistically significance relationship exists between education and homeownership. Regional differences are seen in homeownership, with households located in the northwest region having a higher probability of homeownership than other regions. Differences in the significance of variable representing the household head’s gender, marital status, and occupation on homeownership exist between logit models that include and do not include current income. The most likely reason for these differences is interactions between the variables and a wealth effect.

Impacts of Water Levels on Breeding Canada Geese and the Methodology for Mitigation and Enhancement in the Flathead Drainage, 1984 Annual Report.  

DOE Green Energy (OSTI)

The lower Flathead System Canada Goose Study was initiated to determine population trends and the effects of water level fluctuations on nest and brood habitat on the southern half of Flathead Lake and the lower Flathead River as a result of the operations of Kerr Dam. This report presents data collected during the 1984 field season as part of an ongoing project. Geese used Pablo, Kicking Horse, Ninepipe Reservoirs heavily during late summer and fall. Use of the river by geese was high during the winter, when the reservoirs were frozen, and during the breeding period. Most breeding geese left the river after broods fledged. Thirteen percent of the artificial tree nest structures on the river were used by nesting geese. Goose nest initiation on the river peaked the last week in March through the first week in April, and hatching peaked the first week in May. Predation was the most significant cause of nest loss on the river, and nest loss by flooding was not observed. Avian predation was the single largest factor contributing to nest loss on the lake. Habitat use was studied in 4 brood areas on the river and 8 brood areas on the lake, and available habitat was assessed for 2 portions of both the lake and the river. Brood habitat use was significantly different from the available habitat in all areas studied. On the lower river, broods used wheat fields, gravel bars, and shrub habitats. On the upper river, coniferous forest and shrub habitats were preferred. On the West Bay of the lake, brood areas consisted primarily of lawns and tall herbaceous habitat, while on the South Bay, marshes dominated the brood areas studied. Water levels on the river and lake affect both accessibility of these areas to brooding geese, and the ecology of the habitats preferred by geese. 43 refs., 24 figs., 31 tabs.

Characterization and Monitoring Data for Evaluating Constructed Emergent Sandbar Habitat in the Missouri River Mainstem 2004-2009  

SciTech Connect

The U.S. Army Corps of Engineers (Corps) provides the primary operational management of the Missouri River Main Stem Reservoir System. Management of the Missouri River has generally reduced peak river flows that form and maintain emergent sandbar habitat. Emergent sandbars provide non-vegetated nesting habitat for the endangered interior least tern (Sternula antillarum athalassos) and the threatened Northern Great Plains piping plover (Charadrius melodus). Since 2000, piping plover nesting habitat within the Gavins Point Reach, Garrison Reach, Lake Oahe, and Lake Sakakawea has fledged the majority of piping plovers produced along the Missouri River system. Habitats within Lewis and Clark Lake have also recently become important plover production areas. Mechanical construction of emergent sandbar habitat (ESH) within some of these reaches within the Missouri River began in 2004. Through 2009, 11 sandbar complexes had been constructed (10 in Gavins Point Reach, 1 in Lewis and Clarke Lake) totaling about 543 ac of piping plover and interior least tern nesting habitat. ESH Construction has resulted in a net gain of tern and plover nesting habitat. Both terns and plovers successfully nest and fledge young on constructed sandbars, and constructed habitats were preferred over natural habitats. Natural processes may limit the viability of constructed sandbars as nesting habitat. Continued research is needed to identify if changes in constructed sandbar engineering and management increase the length of time constructed habitats effectively function as nesting habitat. However, the transfer of information from researchers to planners through technical research reports may not be timely enough to effectively foster the feedback mechanisms of an adaptive management strategy.

Pulse pileup statistics for energy discriminating photon counting x-ray detectors  

SciTech Connect

Purpose: Energy discriminating photon counting x-ray detectors can be subject to a wide range of flux rates if applied in clinical settings. Even when the incident rate is a small fraction of the detector's maximum periodic rate N{sub 0}, pulse pileup leads to count rate losses and spectral distortion. Although the deterministic effects can be corrected, the detrimental effect of pileup on image noise is not well understood and may limit the performance of photon counting systems. Therefore, the authors devise a method to determine the detector count statistics and imaging performance. Methods: The detector count statistics are derived analytically for an idealized pileup model with delta pulses of a nonparalyzable detector. These statistics are then used to compute the performance (e.g., contrast-to-noise ratio) for both single material and material decomposition contrast detection tasks via the Cramer-Rao lower bound (CRLB) as a function of the detector input count rate. With more realistic unipolar and bipolar pulse pileup models of a nonparalyzable detector, the imaging task performance is determined by Monte Carlo simulations and also approximated by a multinomial method based solely on the mean detected output spectrum. Photon counting performance at different count rates is compared with ideal energy integration, which is unaffected by count rate. Results: The authors found that an ideal photon counting detector with perfect energy resolution outperforms energy integration for our contrast detection tasks, but when the input count rate exceeds 20%N{sub 0}, many of these benefits disappear. The benefit with iodine contrast falls rapidly with increased count rate while water contrast is not as sensitive to count rates. The performance with a delta pulse model is overoptimistic when compared to the more realistic bipolar pulse model. The multinomial approximation predicts imaging performance very close to the prediction from Monte Carlo simulations. The monoenergetic image with maximum contrast-to-noise ratio from dual energy imaging with ideal photon counting is only slightly better than with dual kVp energy integration, and with a bipolar pulse model, energy integration outperforms photon counting for this particular metric because of the count rate losses. However, the material resolving capability of photon counting can be superior to energy integration with dual kVp even in the presence of pileup because of the energy information available to photon counting. Conclusions: A computationally efficient multinomial approximation of the count statistics that is based on the mean output spectrum can accurately predict imaging performance. This enables photon counting system designers to directly relate the effect of pileup to its impact on imaging statistics and how to best take advantage of the benefits of energy discriminating photon counting detectors, such as material separation with spectral imaging.

The Determinants of Hazardous Waste Disposal Choice:  

E-Print Network (OSTI)

In this paper, we estimate conditional logit models of generator’s choice of waste management facilities (TSDFs) for shipments of halogenated solvent waste documented by the manifests filled out in California in 1995. We find that the probability that a facility is selected as the destination of an off-site shipment of halogenated solvent waste depends on the cost of shipping and disposal at that facility, on measures of existing contamination at the site, and on the track record of the receiving facility. Generators do seem to balance current disposal costs with the likelihood of future liability, should the TSDF become involved in either the state or federal Superfund program. In general, we find no evidence that generators prefer “wealthier ” TSDFs or “larger ” facilities, suggesting that there is a role for smaller, private companies in the management of halogenated solvent waste. When attention is limited to so-called “restricted ” wastes containing halogenated compounds, which cannot be landfilled, the best match between the waste and the treatment offered by the facility may be more important than saving on the cost of disposal, and price may even be interpreted as a signal for quality of the facility. 3

PRICE RIGIDITY ON THE INTERNET: NEW EVIDENCE FROM THE ONLINE BOOKSELLING INDUSTRY  

E-Print Network (OSTI)

This study reports on an econometric analysis of a new theoretical model for price rigidity in Internet-based bookselling. We consider a variety of theoretical perspectives from marketing and economics. We specify and test a model using data on 387 books sold on the Internet that were collected over a 309-day period in 2003 and 2004. The aggregate data are built based on 1,162,149 daily observations, and provide a reading on the variation in prices of homogeneous products for between three and eleven different “stores ” on the Internet. We obtained a number of interesting findings from the estimation of the grouped logit model. More frequent price adjustments in Internet-based selling appear to be associated with higher-priced goods, consumer expectations of ongoing price promotions, and popular products. Nine-price endings are associated with greater price rigidity, as are low-priced products. We also found that Internetbased sellers use shipping fees as a means to adjust prices. Taken together, our results indicate the roles of both price elements and non-price elements in explaining price rigidity.

Assessment Of Carbon Leakage In Multiple Carbon-Sink Projects: ACase Study In Jambi Province, Indonesia  

Science Conference Proceedings (OSTI)

Rehabilitation of degraded forest land throughimplementation of carbon sink projects can increase terrestrial carbonstock. However, carbon emissions outside the project boundary, which iscommonly referred to as leakage, may reduce or negate the sequestrationbenefits. This study assessed leakage from carbon sink projects thatcould potentially be implemented in the study area comprised of elevensub-districts in the Batanghari District, Jambi Province, Sumatra,Indonesia. The study estimates the probability of a given land use/coverbeing converted into other uses/cover, by applying a logit model. Thepredictor variables were: proximity to the center of the land use area,distance to transportation channel (road or river), area of agriculturalland, unemployment (number of job seekers), job opportunities, populationdensity and income. Leakage was estimated by analyzing with and withoutcarbon sink projects scenarios. Most of the predictors were estimated asbeing significant in their contribution to land use cover change. Theresults of the analysis show that leakage in the study area can be largeenough to more than offset the project's carbon sequestration benefitsduring the period 2002-2012. However, leakage results are very sensitiveto changes of carbon density of the land uses in the study area. Byreducing C-density of lowland and hill forest by about 10 percent for thebaseline scenario, the leakage becomes positive. Further data collectionand refinement is therefore required. Nevertheless, this study hasdemonstrated that regional analysis is a useful approach to assessleakage.

The Distributive Impact Assessment Model (DIAM): Technology share component  

DOE Green Energy (OSTI)

The models described in this report are used to allocate total energy consumption in an energy end-use service area by fuel type (including electricity) within the Distributive Impact Assessment Model (DIAM) framework. The primary objective of the DIAM is to provide energy consumption and expenditure forecasts for different population categories that are consistent with the US Department of Energy (DOE) Energy Information Administration`s (EIA`s) National Energy Modeling System (NEMS) forecast, which is produced annually in the Annual Energy Outlook and periodically in support of DOE policy formulation and analysis. The models are multinominal logit models that have been estimated using EIA`s 1990 Residential Energy Consumption Survey. Three models were estimated: space heating share, water heating share, and cooking share. These models are used to allocate total end-use service consumption over different technologies defined by fuel type characteristics. For each of the end-use service categories, consumption shares are estimated for a subset of six fuel types: natural gas, electricity, liquid petroleum gas, fuel oil/kerosene, wood, and other fuel.

Electric and hybrid electric vehicles: A technology assessment based on a two-stage Delphi study  

DOE Green Energy (OSTI)

To address the uncertainty regarding future costs and operating attributes of electric and hybrid electric vehicles, a two stage, worldwide Delphi study was conducted. Expert opinions on vehicle attributes, current state of the technology, possible advancements, costs, and market penetration potential were sought for the years 2000, 2010, and 2020. Opinions related to such critical components as batteries, electric drive systems, and hybrid vehicle engines, as well as their respective technical and economic viabilities, were also obtained. This report contains descriptions of the survey methodology, analytical approach, and results of the analysis of survey data, together with a summary of other factors that will influence the degree of market success of electric and hybrid electric vehicle technologies. Responses by industry participants, the largest fraction among all the participating groups, are compared with the overall responses. An evaluation of changes between the two Delphi stages is also summarized. An analysis of battery replacement costs for various types is summarized, and variable operating costs for electric and hybrid vehicles are compared with those of conventional vehicles. A market penetration analysis is summarized, in which projected market shares from the survey are compared with predictions of shares on the basis of two market share projection models that use the cost and physical attributes provided by the survey. Finally, projections of market shares beyond the year 2020 are developed by use of constrained logit models of market shares, statistically fitted to the survey data.

Infant mortality at birth may help illuminate the usefulness of season of birth as an indicator of early life exposures. We obtained data for infant mortality rates (IMR) at the county (municipio) level during the late 1920s-early 1940s in Puerto Rico using historical records and linked IMR with individual birth year and place using the PREHCO (Puerto Rican Elderly: Health Conditions) study. We classified PREHCO respondents into two groups according to high or low infectious disease load, corresponding to lower or higher proportion endogenous mortality in the year respondents were born. We estimated the effects of IMR (using continuous, logit, quartile, Box-Cox transformations) and season of birth on adult heart disease and diabetes for all respondents and then by subgroups, controlling for age, gender, obesity, respondent’s educational level, adult behavior (smoking, exercise) and other early life exposures (childhood health, knee height, childhood SES). Findings: (1) no significant associations between IMR and heart disease or diabetes but significant associations between high IMR and low knee height, low education, older age and no rigorous exercise as an adult; (2) stronger effects of season of birth on adult health among respondents born in years with lower infectious disease loads; (3) strong

Momentum-space Electronic Structures and Charge Orders of the High-temperature Superconductors Ca2?xNaxCuO2Cl2 and Bi2Sr2CaCu2O8+?  

SciTech Connect

We study the electronic structure of Ca{sub 2-x}Na{sub x}CuO{sub 2}Cl{sub 2} and Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} samples in a wide range of doping, using angle-resolved photoemission spectroscopy, with emphasis on the Fermi surface (FS) in the near antinodal region. The 'nesting wave vector,' i.e., the wave vector that connects two nearly flat pieces of the FS in the antinodal region, reveals a universal monotonic decrease in magnitude as a function of doping. Comparing our results to the charge order recently observed by scanning tunneling spectroscopy (STS), we conclude that the FS nesting and the charge order pattern seen in STS do not have a direct relationship. Therefore, the charge order likely arises due to strong-correlation physics rather than FS nesting physics.

Only 1 of 3 sites was developed for wind power, the 201MW Meridan Way Wind Power Facility at the Smoky Hills site in northcentral Kansas. Our project report is based on population data for prairie chickens collected during a 2-year preconstruction period (2007-2008), a 3-year postconstruction period (2009-2011) and one final year of lek surveys (2012). Where relevant, we present preconstruction data from our field studies at reference sites in the northern Flint Hills (2007-2009) and southern Flint Hills (2006-2008). 2. We addressed seven potential impacts of wind power development on prairie chickens: lek attendance, mating behavior, use of breeding habitat, fecundity rates, natal dispersal, survival rates, and population numbers. Our analyses of pre- and postconstruction impacts are based on an analysis of covariance design where we modeled population performance as a function of treatment period, distance to eventual or actual site of the nearest wind turbine, and the interaction of these factors. Our demographic and movement data from the 6-year study period at the Smoky Hills site included 23 lek sites, 251 radio-marked females monitored for 287 bird-years, and 264 nesting attempts. Our genetic data were based on genotypes of 1,760 females, males and chicks that were screened with a set of 27 microsatellite markers that were optimized in the lab. 3. In our analyses of lek attendance, the annual probability of lek persistence during the preconstruction period was ~0.9. During the postconstruction period, distance to nearest turbine did not have a significant effect on the probability of lek persistence. However, the probability of lek persistence increased from 0.69 at 0 m to 0.89 at 30 km from turbines, and most abandoned lek sites were located 0.9 for leks of 10 or more males. Large leks in grasslands should be a higher priority for conservation. Overall, wind power development had a weak effect on the annual probability of lek persistence. 3. We used molecular methods to investigate the mating behavior of prairie chickens. The prevailing view for lek-mating grouse is that females mate once to fertilize the clutch and that conspecific nest parasitism is rare. We found evidence that females mate multiple times to fertilize the clutch (8-18% of broods, 4-38% of chicks) and will parasitize nests of other females during egg-laying (~17% of nests). Variable rates of parentage were highest in the fragmented landscapes at the Smoky Hills field site, and were lower at the Flint Hills field site. Comparisons of the pre- and postconstruction periods showed that wind energy development did not affect the mating behaviors of prairie chickens. 4. We examined use of breeding habitats by radio-marked females and conducted separate analyses for nest site selection, and movements of females not attending nests or broods. The landscape was a mix of native prairie and agricultural habitats, and nest site selection was not random because females preferred to nest in grasslands. Nests tended to be closer to turbines during the postconstruction period and there was no evidence of behavioral avoidance of turbines by females during nest site selection. Movements of females not attending nests or broods showed that females crossed the site of the wind power development at higher rates during the preconstruction period (20%) than the postconstruction period (11%), and that movements away from turbines were more frequent during the postconstruction period. Thus, wind power development appears to affect movements in breeding habitats but not nest site s

BAMBI: blind accelerated multimodal Bayesian inference  

E-Print Network (OSTI)

In this paper we present an algorithm for rapid Bayesian analysis that combines the benefits of nested sampling and artificial neural networks. The blind accelerated multimodal Bayesian inference (BAMBI) algorithm implements the MultiNest package for nested sampling as well as the training of an artificial neural network (NN) to learn the likelihood function. In the case of computationally expensive likelihoods, this allows the substitution of a much more rapid approximation in order to increase significantly the speed of the analysis. We begin by demonstrating, with a few toy examples, the ability of a NN to learn complicated likelihood surfaces. BAMBI's ability to decrease running time for Bayesian inference is then demonstrated in the context of estimating cosmological parameters from WMAP and other observations. We show that valuable speed increases are achieved in addition to obtaining NNs trained on the likelihood functions for the different model and data combinations. These NNs can then be used for an...

In this paper I provide a brief overview of modal and tense logic, their semantics, and the nested sequent calculus. I detail how structural rules can be added to a logical system using a process involving Scott-Lemmon axioms, and how path axioms can be added to systems by analyzing their effect on Kripke frames. I show logical rules for the shallow and deep inference on the nested sequent calculus systems SKt and DKt, and show how the deep inference system can eliminate structural rules, thus aiding proof search over the systems. Finally, I provide an extension of the nested sequent calculus with seriality, and then show how further extensions of these new systems SKt+D and DKt+D are possible using

WINDOW OPENING BEHAVIOUR IN A NATURALLY VENTILATED SCHOOL  

E-Print Network (OSTI)

Several studies have highlighted the significant disparities between the predicted performance of new buildings and their post occupancy measured performance. Occupant window opening behaviour has been shown to have a significant impact on both classroom indoor air quality and building energy use; and is currently poorly represented in building simulation tools. A post occupancy assessment of a new primary school was performed over a period of over one year. Concurrent measurement of window open state, CO2 concentration, temperature, and exterior environmental conditions were taken at a frequency of two minutes. In addition, classroom daily occupancy levels and monthly building energy usage were recorded. A probabilistic model of the proportion of windows open throughout the day as the occupants interact with the windows was developed based on the results of multinomial logistic regression analysis. The model was used to schedule window opening in the EnergyPlus simulation program. Predictions of both CO2 concentration and building energy performance, using the occupant behaviour model, were shown to give more accurate predictions than a model based on temperature set points.

Population dynamics and movements of the Kemp's ridley sea turtle, lepidochelys kempii, in the northwestern Gulf of Mexico  

E-Print Network (OSTI)

The Kemp’s ridley sea turtle, Lepidochelys kempii, is recovering from devastating declines that reduced nesting activity from a single-day estimate of 10,000- 40,000 females in 1947 to fewer than 300 during all of 1985. Nesting beach monitoring is crucial to estimating population size and reproductive activity, but in-water data are essential for understanding population dynamics and evaluating management strategies. Hook-and-line, stranding, and nesting records, satellite telemetry, and diet analyses were used to characterize ridley population dynamics and movements in the northwestern Gulf of Mexico during 2003-2007. Recreational hook-and-line captures comprised approximately one third of non-nesting encounters along Galveston and Jefferson Counties, Texas. The hook-and-line dataset displayed similar geographical and monthly trends to that of strandings, but was devoid of pelagic-stage, subadult, and adult ridleys. Coastal and bay waters along the upper Texas and western Louisiana coasts were utilized by immature ridleys during warmer months. Nesting occurred along Galveston Island on both armored and unarmored beaches. Inter-nesting females exhibited fidelity to Galveston during nesting season and subsequently migrated to federal waters offshore Louisiana. Crabs were important components of benthic-stage (>25 cm SCL) ridley diet, while worm tubes were targeted by some individuals. Short satellite track durations for immature ridleys precipitated examinations of biofouling, attachment protocols, and turtle excluder device (TED) interactions. Antifouling paints drastically reduced fouling of transmitters. A less-rigid neoprene attachment method was developed to increase transmitter retention on fast-growing juveniles, but further trials are necessary. Transmitters were not damaged or lost during TED trials, but turtle escape times increased when transmitters wedged between TED bars. Projected population growth will increase numbers of Kemp’s ridleys utilizing the Gulf of Mexico and interacting with human activities. Future research should examine year-round distribution and abundance of all life history stages and further characterize recreational hook-and-line capture, nesting activity, movements, and diet. Education efforts targeting the beach-going public, beach residents and workers, and the recreational fishing sector should be employed to promote sea turtle reporting and minimize negative interactions. State and federal managers should examine anthropogenic impacts within the region and determine the need for mitigation and/or regulations to promote continued species recovery.

Formation of Antihydrogen Rydberg atoms in strong magnetic field traps  

SciTech Connect

It is shown that several features of antihydrogen production in nested Penning traps can be described with accurate and efficient Monte Carlo simulations. It is found that cold deeply-bound Rydberg states of antihydrogen (H-bar) are produced in three-body capture in the ATRAP experiments and an additional formation mechanism -Rydberg charge transfer-, particular to the nested Penning trap geometry, is responsible for the observed fast (hot) H-bar atoms. Detailed description of the numerical propagation technique for following extreme close encounters is given. An analytic derivation of the power law behavior of the field ionization spectrum is provided.

This paper is concerned with the use of the choice experiment method for modelling the demand for recreation, using the example of rock-climbing in Scotland. We begin by outlining the method itself, including its theoretical and econometric underpinnings. Data collection procedures are then outlined. We present results from both nested and non-nested models, and report some tests for the implications of choice complexity and rationality. Finally, we compare our results with a revealed preference data model based on the same sample of climbers.

Minimum/maximum autocorrelation factor (MAF) is a suitable algorithm for orthogonalization of a vector random field. Orthogonalization avoids the use of multivariate geostatistics during joint stochastic modeling of geological attributes. This manuscript demonstrates in a practical way that computation of MAF is the same as discriminant analysis of the nested structures. Mathematica software is used to illustrate MAF calculations from a linear model of coregionalization (LMC) model. The limitation of two nested structures in the LMC for MAF is also discussed and linked to the effects of anisotropy and support. The analysis elucidates the matrix properties behind the approach and clarifies relationships that may be useful for model-based approaches.

Development of Improved Traveler Survey Methods for High-Speed Intercity Passenger Rail Planning  

E-Print Network (OSTI)

High-speed passenger rail is seen by many in the U.S. transportation policy and planning communities as an ideal solution for fast, safe, and resource-efficient mobility in high-demand intercity corridors. To expand the body of knowledge for high-speed intercity passenger rail in the U.S., the overall goal of this dissertation was to better understand the demand for high-speed intercity passenger rail services in small- or medium-sized intermediate communities and improve planners' ability to estimate such demand through traveler surveys; specifically, the use of different experimental designs for stated preference questions and the use of images to describe hypothetical travel alternatives in traveler surveys. In pursuit of this goal, an Internet-based survey was distributed to residents of Waco and Temple, two communities located along the federally-designated South Central High-Speed Rail Corridor in Central Texas. A total of 1,160 surveys were obtained from residents of the two communities. Mixed logit travel mode choice models developed from the survey data revealed valuable findings that can inform demand estimates and the design of traveler surveys for high-speed intercity passenger rail planning activities. Based on the analysis presented in this dissertation, ridership estimates for new high-speed intercity passenger rail lines that are planned to serve intermediate communities should not assume that residents of these communities have similar characteristics and values. The d-efficient stated preference experimental design was found to provide a mode choice model with a better fit and greater significance on key policy variables than the adaptive design and therefore is recommended for use in future surveys. Finally, it is recommended that surveys should consider the use of images of proposed train services to aid respondent decision-making for stated preference questions, but only if the images used in the survey depict equipment that could be realistically deployed in the corridor.

Acemannan-containing wound dressing gel reduces radiation-induced skin reactions in C3H mice  

Science Conference Proceedings (OSTI)

To determine (a) whether a wound dressing gel that contains acemannan extracted from aloe leaves affects the severity of radiation-induced acute skin reactions in C3H mice; (b) if so, whether other commercially available gels such as a personal lubricating jelly and a healing ointment have similar effects; and (c) when the wound dressing gel should be applied for maximum effect. Male C3H mice received graded single doses of gamma radiation ranging from 30 to 47.5 Gy to the right leg. In most experiments, the gel was applied daily beginning immediately after irradiation. Dose-response curves were obtained by plotting the percentage of mice that reached or exceeded a given peak skin reaction as a function of dose. Curves were fitted by logit analysis and ED{sub 50} values, and 95% confidence limits were obtained. The average peak skin reactions of the wound dressing gel-treated mice were lower than those of the untreated mice at all radiation doses tested. The ED{sub 50} values for skin reactions of 2.0-2.75 were approximately 7 Gy higher in the wound dressing gel-treated mice. The average peak skin reactions and the ED{sub 50} values for mice treated with personal lubricating jelly or healing ointment were similar to irradiated control values. Reduction in the percentage of mice with skin reactions of 2.5 or more was greatest in the groups that received wound dressing gel for at least 2 weeks beginning immediately after irradiation. There was no effect if gel was applied only before irradiation or beginning 1 week after irradiation. Wound dressing gel, but not personal lubricating jelly or healing ointment, reduces acute radiation-induced skin reactions in C3H mice if applied daily for at least 2 weeks beginning immediately after irradiation. 31 refs., 4 figs., 1 tab.

Public attitudes toward the use of force and presidential crisis responses  

E-Print Network (OSTI)

This dissertation explores the role of public opinion in U.S. presidential decisions to employ various alternatives in response to an international crisis. Presidents may choose from a range of force alternatives, including non-force alternatives, troop mobilizations, air strikes or ground assaults. Using the Poliheuristic Theory, I argue that public attitudes toward the use of force in a given crisis play a key role in the decision making process leading to such choices. The direction and intensity of public opinion is driven by a relative value assessment by which the public determines whether the benefits of a use of force are worth the costs. Presidents are aware of this relative value assessment and rule out crisis responses that are likely to violate the public's preferences in the first stage of the decision making process. In the second stage, presidents choose among the remaining alternatives by weighing the relative merits of each with respect to military and international-strategic implications. To test hypotheses following from this theoretical argument, I employ two methodological approaches. The first is statistical analysis. I develop a new data set of presidential crisis response choices and expand an existing data set on U.S. public attitudes toward the use of force, from 1949 to 2001. Using two extant data collections identifying international crises, I conduct Ordered Logit analyses, which produce results that are largely supportive of the hypotheses. The second methodological approach is the case study method. I conduct two detailed case studies of decisions to use force in Bosnia (1995) and Afghanistan (2001). These analyses are also supportive of the theoretical argument. I conclude that presidents are largely responsive to public opinion in the selection of crisis responses.

Eisenbeis, Supt. of Conservation THE PASSENGER PIGEON We Americans have been a greedy heedless people plundering and wasting the natural resources which made possible the building of this great nation -- the soils, the waters, the forests, the minerals and the wildlife, In the United States there was once an abundance of wildlife never found on any other land. We have come close to exterminating many valuable kinds, notably the buffalo and the beaver. Several species once abundant are extinct, among them the Passenger Pigeon. The passenger pigeon was a graceful elegant bird with a long wedge- shaped tail, considerably larger than our Mourning Dove and mighty good to eat. The males were handsome: slaty blue and brown above; the head blue; the sides and back of the neck iridescent with pink, purple, green and gold; the breast a rich reddish-brown shading to pinkish on the sides; with short stout red legs. Unlike other doves and pigeons, its voice was rather loud and harsh. The females were more drab in color. Native to the unbroken forests which covered most of central and eastern North America, they nested in huge colonies. An area of 100 square miles might have every tree loaded with nests, some times 100 nests in a single tree. The nests were merely a crisscross jumble of sticks in which one pure-white egg was laid.

Plant community dynamics governed by red harvester ant (Pogonomyrmex barbatus) activities and their role as drought refugia in a semi-arid savanna  

E-Print Network (OSTI)

This study examined modifications made by Pogonomyrmex barbatus, by their processes of granivory and nest construction, to forb and grass dynamics under large-scale disturbances of fire, recent drought and long-term, large-mammalian herbivory using comparative studies, field experimental manipulations, and a simulation model on the Edwards Plateau, Texas. Ant nests are refugia for grass survival during extreme droughts as demonstrated during the drought of 1998 to 2002. Significantly greater cover of grasses and lower abundance and cover of forbs was found beside nests compared with surrounding habitat throughout the drought and recovery. Grasses near nests may be the seed source for surrounding habitats during recovery. Seeds were differentially collected among most forbs and grasses despite seed abundance. Harvest was significantly reduced in the fall relative to spring. During preference experiments, harvest differences were found between grazing treatments for two of four species, but only during the spring. High lipid content seeds were unpreferred in fall compared to high protein and carbohydrate content seeds. Granivory influences on seedling establishment were studied by comparing seedling recruitment among sown and naturally occurring seeds excluded and open to foragers. Exclosures were placed in three nest densities and two burn treatments. Seeds in exclosures produced significantly more seedlings than open arenas only during the first year of drought recovery. Densities of grasses and annual forbs were higher in open arenas the second year due to indirect effects of granivory. By reducing seeds ants release seedlings from competition. Sown seedling abundance was unaffected by colony density and fire. Colony density and distribution were influenced by topography, soil types, soil depth and woody cover, but not by historical grazing treatments. Cleared vegetation on nest disks impacted less than 1% of total surface area and losses were compensated by greater basal cover of grasses next to disks compared to surrounding habitats. Foraging areas influenced 17.3-73.6% of surface area and could diminish seed populations for potential seedlings. Model results agree with experimental observations that communities may be modified by P. barbatus presence due to differential responses of grass species to interaction between nests or granivory and rainfall amounts.

Residential cattle egret colonies in Texas: geography, reproductive success and management  

E-Print Network (OSTI)

A phenomenon of large, upland breeding colonies of cattle egrets in residential areas of Central Texas has been observed since the early 1960s. These large concentrations of breeding birds can be a nuisance to nearby residents and their management has been difficult. To help understand why cattle egrets choose upland, residential breeding sites, and predict where these might occur, the geographic extent of the phenomenon was bounded within Texas, a habitat suitability model constructed, and reproductive success compared by breeding habitat type to evaluate if residential nesting confers an adaptive advantage.. Records of upland cattle egret colonies were found only in Central Texas, not other parts of the state. The habitat suitability model was constructed using total edge of three land use classes: water, forest, and developed classes. The model classified 78.6 % of upland colonies in very high or high suitability classes and 7.1% of colonies in low or very low suitability classes. This distribution was significantly different than expected considering the overall ratio of suitability scores in the entire raster model (p = 0.036). Nineteen active colonies were found in or bordering the Post Oak Savannah and Blackland Prairie ecoregions. Colonies were in residential, urban, island, and flooded tree and shrub habitat. Nests were found in 12 different tree and shrub species. Residential colonies had more breeding pairs, greater nest survival, and were less productive than non-residential colonies on average, but these differences were not statistically significant. Colonies where nest substrate was removed were not reused and no breeding was initiated nearby the next year. Propane cannons discouraged reuse of colony after prolonged application. Herons and egrets likely use residential sites when wetland habitats are limited. Their overall breeding distribution reflects state wide rainfall and wetland availability patterns with upland nesting in Central Texas, wetland nesting in eastern and coastal regions, and little large scale nesting in western Texas. Egrets and herons may use edges of development as breeding sites to limit predation by ground predators when flooded tree and shrub or island habitats are absent, but this hypothesis needs more testing.

Reproductive Peformance of Great Egrets (Ardea alba) at High Island, Texas  

E-Print Network (OSTI)

Despite habitat perturbations and seasonal fluctuations in reproduction, many studies report no significant inter-annual variation in Great Egret reproductive performance. I examined the reproductive performance of Great Egrets (Ardea alba) for two breeding seasons (2009 and 2010) immediately following Hurricane Ike at High Island, Texas. Breeding success, productivity, and mean brood size did not differ between years (U-test, P > 0.05). Fledging success at 21 days showed no significant difference between years, however fledging success at 28, 35, and 42 days decreased significantly between years (~15% reduction at 42 days; U-test, P = 0.027). The number of deaths per nest also differed significantly between 2009 and 2010 (0.36 and 0.95, respectively) (U-test, P = 0.013). Brood-size dependent mortality was also a significant between-year parameter (H test, P = 0.003). Successful nests in 2009 had a brood size range of 2 to 3, and of these nests, 6% and 50% experienced partial brood reduction, respectively; whereas 2010 brood size range for successful nests was 2 to 4, and 0%, 57%, and 100% of these nests, respectively, experienced partial brood reduction. Other parameters examined were water level, temperature, precipitation, prey availability, and human disturbance. I rejected my hypothesis that habitat conditions would be less conducive to high reproductive success in 2009 than 2010, due to the impacts of Hurricane Ike. My results suggest that Great Egrets have bimodal occurrences of nestling death that are expressed as a function of brood size, hatching spread, and nestling age. Reproductive performance studies should continue through at least fledging age (42 days post-hatching for Great Egrets) to better document the reproductive performance, especially by incorporating the apparent behavioral plasticity of nestlings.

Maximum entropy principal for transportation  

SciTech Connect

In this work we deal with modeling of the transportation phenomenon for use in the transportation planning process and policy-impact studies. The model developed is based on the dependence concept, i.e., the notion that the probability of a trip starting at origin i is dependent on the probability of a trip ending at destination j given that the factors (such as travel time, cost, etc.) which affect travel between origin i and destination j assume some specific values. The derivation of the solution of the model employs the maximum entropy principle combining a priori multinomial distribution with a trip utility concept. This model is utilized to forecast trip distributions under a variety of policy changes and scenarios. The dependence coefficients are obtained from a regression equation where the functional form is derived based on conditional probability and perception of factors from experimental psychology. The dependence coefficients encode all the information that was previously encoded in the form of constraints. In addition, the dependence coefficients encode information that cannot be expressed in the form of constraints for practical reasons, namely, computational tractability. The equivalence between the standard formulation (i.e., objective function with constraints) and the dependence formulation (i.e., without constraints) is demonstrated. The parameters of the dependence-based trip-distribution model are estimated, and the model is also validated using commercial air travel data in the U.S. In addition, policy impact analyses (such as allowance of supersonic flights inside the U.S. and user surcharge at noise-impacted airports) on air travel are performed.

T Tank Farm Interim Surface Barrier Demonstration - Vadose Zone Monitoring FY09 Report  

SciTech Connect

DOE’s Office of River Protection constructed a temporary surface barrier over a portion of the T Tank Farm as part of the T Farm Interim Surface Barrier Demonstration Project. As part of the demonstration effort, vadose zone moisture is being monitored to assess the effectiveness of the barrier at reducing soil moisture. A solar-powered system was installed to continuously monitor soil water conditions at four locations (i.e., instrument Nests A, B, C, and D) beneath the barrier and outside the barrier footprint as well as site meteorological conditions. Nest A is placed in the area outside the barrier footprint and serves as a control, providing subsurface conditions outside the influence of the surface barrier. Nest B provides subsurface measurements to assess surface-barrier edge effects. Nests C and D are used to assess changes in soil-moisture conditions beneath the interim surface barrier. Each instrument nest is composed of a capacitance probe (CP) with multiple sensors, multiple heat-dissipation units (HDUs), and a neutron probe (NP) access tube. The monitoring results in FY09 are summarized below. The solar panels functioned normally and could provide sufficient power to the instruments. The CP in Nest C after September 20, 2009, was not functional. The CP sensors in Nest B after July 13 and the 0.9-m CP sensor in Nest D before June 10 gave noisy data. Other CPs were functional normally. All the HDUs were functional normally but some pressure-head values measured by HDUs were greater than the upper measurement-limit. The higher-than-upper-limit values might be due to the very wet soil condition and/or measurement error but do not imply the malfunction of the sensors. Similar to FY07 and FY08, in FY09, the soil under natural conditions (Nest A) was generally recharged during the winter period (October-March) and discharged during the summer period (April-September). Soil water conditions above about 1.5-m to 2-m depth from all three types of measurements (i.e., CP, NP and HDU) showed relatively large variation during the seasonal wetting-drying cycle. For the soil below 2-m depth, the seasonal variation of soil water content was relatively small. The construction of the surface barrier was completed in April 2008. In the soil below the surface barrier (Nests C and D), the CP measurements showed that water content at the soil between 0.6-m and 2.3-m depths was very stable, indicating no climatic impacts on soil water condition beneath the barrier. The NP-measured water content showed that soil water drainage seemed occurring in the soil between about 3.4 m (11 ft) and 9.1 m (30 ft) in FY09. The HDU-measured water pressure decreased consistently in the soil above 5-m depth, indicating soil water drainage at these depths of the soil. In the soil below the edge of the surface barrier (Nest B), the CP-measured water content was relatively stable through the year except at the 0.9-m depth; the NP-measured water content showed that soil water drainage was occurring in the soil between about 3.4 m (11 ft) and 9.1 m (30 ft) but at a slightly smaller magnitude than those in Nests C and D; the HDU-measurements show that the pressure head changes in FY09 in Nest B were less than those for C and D but more than those for A. The soil-water-pressure head was more sensitive to soil water regime changes under dry conditions. In the soil beneath the barrier, the theoretical steady-state values of pressure head is equal to the negative of the distance to groundwater table. Hence, it is expected that, in the future, while the water content become stable, the pressure head will keep decreasing for a long time (e.g., many years). These results indicate that the T Tank Farm surface barrier was performing as expected by intercepting the meteoric water from infiltrating into the soil and the soil was becoming drier gradually. The barrier also has some effects on the soil below the barrier edge but at a reduced magnitude.

Easter Bunnies Easter Bunnies Nature Bulletin No. 61 April 13, 1946 Forest Preserve District of Cook County Clayton F. Smith, President Roberts Mann, Supt. of Conservation EASTER BUNNIES Rabbits do have eggs. But they are only 1/300 of an inch in diameter and develop into young which are born and nursed like other mammals. Molly Cottontail has already had the first of the three or four litters she produces per year in this climate. Each litter numbers from 4 to 6 little rabbits born in a nest which is a shallow hole dug in the ground by the mother, usually in an open field, padded with grass and with fur which she plucks from herself. Their ears are small at first, their eyes are closed, and they have only a coat of fuzz. After about a month they leave the nest and soon are shifting for themselves.

Availability and abundance of prey for the red-cockaded woodpecker.  

SciTech Connect

Red-cockaded woodpecker; Road to Recovery. Proceedings of the 4th Red-cockaded woodpecker Symposium. Ralph Costa and Susan J. Daniels, eds. Savannah, Georgia. January, 2003. Chapter 11. Prey, Fire, and Community Ecology. Pp 633-645. Abstract: Over a 10-year period we investigated red-cockaded woodpecker (Picoides borealis) prey use, sources of prey, prey distribution within trees and stands, and how forest management decisions affect prey abundance in South Carolina, Alabama, Georgia and Florida. Cameras were operated at 31 nest cavities to record nest visits with prey in 4 locations that ranged in foraging habitat from pine stands established in old fields to an old-growth stand in South Georgia. Examination of nearly 12,000 photographs recorded over 5 years revealed that, although red-cockaded woodpeckers used over 40 arthropods for food, the majority of the nestling diet is comprised of a relatively small number of common arthropods.

Sparrows Sparrows Nature Bulletin No. 525 April 12, 1958 Forest Preserve District of Cook County Daniel Ryan, President Roberts Mann, Conservation Editor David H. Thompson, Senior Naturalist NATIVE SPARROWS The commonest bird of our cities and towns, or about buildings in rural regions, is the English Sparrow. This much cussed and discussed immigrant was brought from Europe to America. about a century ago and quickly followed man across the continent. It builds large trashy nests of grass and straw, lined with feathers, under the eaves or roofs of garages, barns, sheds and porches, as well as in birdhouses. It is quarrelsome and they sang together to drive out songbirds. Sometimes it is called the House Sparrow but, strictly speaking, it is one of the Weaver Finches which build nests with a side entrance. It is not a sparrow.

RHIC STATUS AND PLANS.  

Science Conference Proceedings (OSTI)

RHIC ended successfully its second year of operation in January 2002 after a six month run with gold ions and two months of polarized proton collisions. I will review the machine performance and accomplishments, that include reaching design energy (100 GeV/u) and design luminosity during the gold run, and the first high energy (100 GeV) polarized proton collisions. I will also discuss the machine development strategy and the main performance milestones. The goals and plans for the shutdown and the nest run, scheduled to start in November 2002 have been the focus of a RHIC Retreat in March 2002. I will summarize findings and plans for the upcoming run and outline a vision for the nest few years of RHIC operation and upgrades.
