A phenomenological model which has had some success in explaining polarization phenomena and left-right asymmetry in inclusive proton-proton scattering is considered for reactions involving photons and, hopefully, neutrinos. In particular, the reactions (a) gamma + p -> H + X, (b) gamma + p(up) -> pi(+-) = X, and (c) p(up) + p -> gamma + X are considered where gamma = resolved photon, and hyperon H = Lambda0, Sigma+-, etc. Predictions for hyperon polarization in (a) and the asymmetry (in (b) and (c)) provide further tests of this particular model.
