  We report results on two physics topics from the SLD experiment at the SLAC
Linear Collider, using our full sample of 550,000 events of the type e+e- -->
Z0 --> q-q(bar). The electron beam was polarized, enabling the quark and
antiquark hemispheres to be tagged in each event. One physics topic is the
first study of rapidities signed such that positive rapidity is along the quark
rather than antiquark direction. Distributions of ordered differences in signed
rapidity between pairs of particles are analyzed, providing the first direct
observation of baryon number ordering along the q-q(bar) axis. The other topic
is the first direct measurement of A_s, the parity-violating coupling of the Z0
to strange quarks, by measuring the left-right forward-backward production
asymmetry in polar angle of the tagged s-quark. We obtain A_s = 0.895 +-
0.066(stat.) +- 0.062(syst.), which is consistent with the Standard Model and
is currently the most precise measurement of this quantity.
