ABM of Civil Violence: ODD Description

subject

description

This chapter contains a description of the proposed agent-based model, using the well-known “Overview, Design Concepts and Details” protocol. The model was implemented in NetLogo and is based on the same two types of agents—citizens and law-enforcement—as in Epstein’s model, but “citizen” agents have one subtype (“activist”) used for implementing network influence effects. The salient aspects of the model description are centered on the submodels for the risk perception, the expression of hardship in terms of value-sensitive relative deprivation, endogenous legitimacy feedback and network influence effects, which provide extensions to Epstein’s model. The model includes two networks called group and infl (for “influentials”), to represent two different types of social influence (due to small and highly cohesive groups or “activists,” respectively). Network influences were implemented using a form of dispositional contagion. The chapter also includes an outline of the R scripts for pre- and post-processing the model results, using the RNetLogo package.
