We introduce a point process model for inter-gang violence driven by retaliation – a core feature of gang behavior – and multi-party inhibition. Here, a coupled system of statedependent jump stochastic differential equations is used to model the conditional intensities of the directed network of gang rivalries. The system admits an exact simulation strategy based upon Poisson thinning. The mode...

Balasuriya, Lakshika. M.S., Department of Computer Science and Engineering, Wright State University, 2017. Finding Street Gang Member Profiles on Twitter The crime and violence street gangs introduce into neighborhoods is a growing epidemic in cities around the world. Today, over 1.4 million people, belonging to more than 33,000 gangs, are active in the United States, of which 88% identify them...

There has been a call to better link public health and criminal justice approaches to best address crime problems generally, and youth and gang violence in particular. Importantly, there has yet to be a systematic examination of how criminal justice approaches can be integrated within a public health framework. This paper examines the strengths and challenges with mapping gang research and evid...

Life within a gang includes two endemic features: violence and alcohol. Yet, to date, most researchers studying gang behavior have focused on violence and its relationship to illicit drugs, largely neglecting the importance of alcohol in gang life. Because alcohol is an integral and regular part of socializing within gang life, drinking works as a social lubricant, or social glue, to maintain n...

Environmental criminologists are at the vanguard of a growing interest in establishing the density or intensity of crime events around locations that are the target of crime prevention activities. The traditional approach has often been to count the number of crime events within a certain distance of the target site; however, this approach is fraught with methodological concerns. In this articl...

In this paper we study the performance of a distributed system which is subject to hardware failures and subsequent repairs. A special type of scheduling called gang scheduling is considered, under which jobs consist of a number of interacting tasks which are scheduled to run simultaneously on distinct processors. System performance is examined and compared in cases where different distribution...

Gang scheduling is a job scheduling policy for parallel computers that combines elements of space-sharing and time-sharing. In this paper, we analyze the performance of gang scheduling policies that allow the remapping of an executing job to a new set of processors. Most previously proposed gang-scheduling policies do not allow such job remapping under the assumption that it is prohibitively ex...

This study compares the scope and nature of the gang problem in two communities: one in the United States and one in Trinidad and Tobago, a small-island developing state in the eastern Caribbean that has experienced a serious outbreak of violence over the past decade. Data drawn from surveys of adult arrestees reveal that among respondents, 3.2% of those in the U.S. sample and 5.1% of those in ...
