  We motivate lattice QCD studies of the parity-violating pion-nucleon coupling
constant and extend flavor-conserving hadronic parity-violation from QCD to
partially-quenched QCD. The parity-violating pion-nucleon coupling and the
anapole form factor (and moment) of the proton are computed to one-loop order
in the partially-quenched chiral expansion. For the parity-violating
pion-nucleon interaction, we include the contributions from total derivative
operators necessary to match the kinematics that will be used in lattice
simulations.
