Abstract: We report on the measurement of parity-violating asymmetries in the deep inelastic scattering and nucleon resonance regions using inclusive scattering of longitudinally polarized electrons from anunpolarized deuterium target. The effective weak couplings C$_{2q}$ areaccessible through the deep-inelastic scattering measurements. Here we report a measurementof the parity-violating asymmetry, which yields a determination of 2C$_{2u}$ - C$_{2d}$ with an improved precision of a factor of five relative to the previous result. This result indicates evidence with 95% confidence that the 2C$_{2u}$ - C$_{2d}$ is non-zero. This experiment also provides the first parity-violation data covering the whole resonance region, which provideconstraints on nucleon resonance models. Finally, the program to extend thesemeasurements at Jefferson Lab in the 12 GeV era using the SolenoidalLarge Intensity Device was also discussed.
