This aspect involves single-spin polarization, gluon polarization, and the correlation between quark spins for massive final state quarks.20 pages in LaTeX, including 8 Postscript figures, invited talk given at the Institute for Physics, Tartu University, Estonia, May 14th, 2002High Energy Physics - Phenomenologytext
