We have previously interpreted the various large apparent violations of the naïve Okubo-Zweig-Iizuka (OZI) rule found in many channels inpp annihilation at LEAR as evidence for an intrinsic polarized ss component of the nucleon wave function. The model is further supported by new data from LEAR and elsewhere. Here we discuss in more detail the possible form of thess component of the nucleon wave function, interpret the new data and clarify the relative roles of strangeness shake-out and rearrangement, discuss whether alternative interpretations are still allowed by the new data, and propose more tests of the model.
