  Multiple initial state parton interactions in p(d)+A collisions are
calculated in a Glauber-Eikonal formalism, which incorporates the competing
pattern of low-pT suppression due geometrical shadowing, and a moderate-pT
Cronin enhancement of hadron spectra. Dynamical shadowing effects, which are
not included in the computation, may be extracted by comparing experimental
data to the baseline provided by the Glauber-Eikonal model. Data for neutral
pion production at midrapidity show absence of dynamical shadowing in the RHIC
energy range, sqrt(s)~20-200 GeV. Recent preliminary data at forward rapidity
are addressed, and their interpretation discussed.
