This monograph develops a finite difference algorithm for studying two-dimensional wave breaking in the vertical plane. The methodology introduced allows a self-contained study for wave transformation processes in shallow water before, during and after the breaking of the wave.

This Brief revisits and extends Epstein's classical agent-based model of civil violence by considering important mechanisms suggested by social conflict theories. Among them are: relative deprivation as generator of hardship, generalized vanishing of the risk perception ('massive fear loss') when the uprisings surpass a certain threshold, endogenous legitimacy feedback, and network influence effects represented by the mechanism of dispositional contagion. The model is explored in a set of computer experiments designed to provide insight on how mechanisms lead to increased complexity of the...
