Nucleon Spin Distributions From Recent SMC, SLAC and DESY Data
  We have extracted polarized nucleon distributions from recent data at CERN, SLAC and DESY. The flavor-dependent valence and sea quark spin distributions are determined for each experiment. The up and down distributions are comparable, but the strange sea contribution determined from different experiments do not agree, even including higher order corrections. Only experiments sensitive to the polarized gluon and sea will reconcile these differences.
