The parton recombination model relates polarizations in inclusive baryon fragmentation to those of the underlying constituent subprocesses. Measurements of spin-spin correlations in experiments using polarized beams will provide detailed information on the quark spin dynamics in the color-confining recombination process. We present a large number of predictions for the octet baryon\ensuremath{\rightarrow}octet baryon transitions. We discuss the production of polarized ${\ensuremath{\Omega}}^{\mathrm{\ensuremath{-}}}$'s, required to measure the magnetic moment of the ${\ensuremath{\Omega}}^{\mathrm{\ensuremath{-}}}$. We also review the data from unpolarized beam experiments, and find very satisfactory agreement between experiment and theory.
