The social organization of street gangs has remained an empirical topic of interest for decades. In part, this may be due to the fact that different sources of data often reveal varied levels of organization.

Gang membership should be acknowledged as part of crime prevention and policy designs, and when developing interventions and preventative programmes. Correctional services are designed to rehabilitate convicted offenders. We formulate a deterministic mathematical model using nonlinear ...

Mapping and other informationcollecting and -ordering techniques, usually a...
