An analytic model of current-hadronic interactions is used to make predictions which are compared with recent data for vector-meson electroproduction and for the spin density matrix of photoproduced rho$sup 0$ mesons. The rho$sup 0$ and $omega$ electroproduction cross sections are predicted to behave differently as the mass of the virtual photon varies; the diffraction peak broadens with increasing -q$sup 2$ at fixed $nu$ and narrows with increasing energy. The predicted rho$sup 0$ density matrix elements do not possess the approximate s-channel helicity conservation seen experimentally. The model is continued to the inclusive electron-positron annihilation region, where parameter-free predictions are given for the inclusive process e$sup +$ + e$sup - $ $Yields$ p + hadrons. The annihilation structure functions are found to have nontrivial scale-invariance limits. By using total cross-section data for e$sup +$$e$$sup -$ annihilation into hardrons, we predict the mean multiplicity for the production of nucleons.
