Model - Independent Remarks Qn Electron - Quark Parity - Violating Neutral - Current Couplings

Present experiments on atomic parity-violation in bismuth and'on polarization asymmetry in electron-nucleon deep-inelastic scattering should allow determination of three out of four of the phenomenological parity violating Fermi-couplings of electrons to up and down quarks. The fourth may be obtained via measurement of atomic parity violation in deuterium (but not hydrogen). We also examine the question of corrections to the parton model in the deep-inelastic asymmetry measurements and argue, from a model independent starting point, that they should be small.
