Parity-violating effects in the (quasi)elastic scattering of longitudinally polarized electrons from spin-1/2 targets are discussed in the framework of the unified gauge theories of weak and electromagnetic interactions. In particular, the R-L asymmetry in electroproduction of the ..delta..(1232) is studied in considerable detail, taking into account the full spin-3/2 structure of this resonance. Our results are valid for all values E and the entire range of Q/sup 2/. Numerical predictions are given for the standard Weinberg-Salam model at several energies of the electron beam.
