In the context of quantum chromodynamics (QCD), an analysis is presented of a compilation of eN deep-inelastic scattering data taken at SLAC. Included are data for F/sup e/p/sub 2/, F/sup e/d/sub 2/, F/sup e/p/sub 2/-F/sup e/n/sub 2/, and R. The interaction between the logarithmic scaling violation from ..cap alpha../sub s/ and the power-law scaling violation from higher-twist terms is discussed. This interaction can affect the determination of the parameter ..lambda.. and can alter the predictions for the ratios of anomalous dimensions. Furthermore, we show that, in the context of QCD, higher-twist terms may be able to account for the observed value of R=sigma/sub L//sigma/sub T/ which appears to be anomalously large. Different experiments have made different assumptions for the value of R used in extracting F/sub 2/ from their data. We show that these differences can account for the discrepancies in the relative normalizations of F/sub 2/ from these experiments and also can have a significant effect on the value of ..lambda.. obtained.
