"Polarized Parton Densities"</font></b>
<br>
<br>
We present the results from the second-ever NLO QCD combined analysis
<br>
of the world data on polarized inclusive and semi-inclusive deep
<br>
inelastic scattering, recently carried out by the LSS Collaboration.
<br>
We discuss in particular the controversy concerning the strange quark
<br>
polarization and the question of Higher Twist terms in the expression
<br>
for g_1.
