چکیده

The Zaller theory of opinion formation is reformulated with one free parameter µ, which measures the largest possible ideological distance which can be made by a citizen in one mental step. Our numerical results show the transient effects: i) the political awareness, measured by the number of received messages, increases with time first exponentially, later linearly; ii) for small µ correlations are present between previously and newly received messages; iii) these correlation lead to a hyperdiffusion effect in the space of attitudes of messages. Citizens with small µ are more prone to extremal opinions.

We give a short overview of the phenomenology of azimuthal and transverse single spin asymmetries in (un)polarized high-energy hadronic collisions. We briefly summarize a transverse momentum dependent, generalized parton model approach to these polarization phenomena, and discuss some of its applications. Finally, open points and future developments will be outlined.
