  We present an improved method for handling off-shell effects in deep
inelastic nuclear scattering. With a firm understanding of the effects of the
nuclear wave function, including these off-shell corrections as well as binding
and nucleon-nucleon correlations, we can begin to examine the role of QCD in
nuclei through an analysis of the moments of the nuclear structure function.
Our analysis is aimed at extracting the Q^2 dependence of the moments of the
nucleon structure function by using the recent high x world Iron data and by
properly removing nuclear effects from the perturbative contribution. In
addition, we compare quantitatively the behavior of the extracted moments with
a simple O(1/Q^2) phenomenological form and we determine the mass term for this
parametrization.
