  We present results using a new scaling variable, xi_w in modeling electron-
and neutrino-nucleon scattering cross sections with effective leading order
PDFs.Our model uses all inelastic charged lepton F_2 data
(SLAC/BCDMS/NMC/HERA), and photoproduction data on hydrogen and deuterium. We
find that our model describes all inelastic scattering charged lepton data, the
average of JLAB resonance data, and neutrino data at all Q2. This model is
currently used by current neutrino oscillation experiments in the few GeV
region.
