  Using QCD motivated and phenomenological considerations, we construct x-
dependent polarized parton distributions, which evolve under GLAP evolution,
satisfy DIS data and are within positivity constraints. Each flavor is done
separately and the overall set can be used to predict polarization asymmetries
for various processes. We perform our NLO analysis strictly in x space,
avoiding difficulties in moment inversion. Small-x results and other physical
considerations are discussed.
