BACKGROUND Many studies document a robust and consistent relationship between gang membership and elevated delinquency, with gang members disproportionately involved in crime compared to non-gang peers. Research also indicates that both delinquent youth and youth who join gangs often show a wide range of deficient or distorted social-cognitive processes compared to non-delinquent peers. Cogniti...

A preemptive gang scheduler is developed and evaluated. The gang scheduler, called SCoreD , is implemented on top of a UNIX operating system and runs on workstation and PC clusters connected by Myrinet, a giga-bit class, high-performance network. To have high-performance communication at the user-level and a multiuser environment simultaneously, we propose network preemption to save and restore...

In this paper we explore the performance of various aspects of gang scheduling designs. We developed an event-driven simulator of a vanilla gang scheduler that relies on the Distributed Hierarchical Control (DHC) structure. We also developed three variations of the vanilla gang scheduler that rely on a push-down heuristic and on two job-migration schemes to decrease response times by reducing p...

Social disorganization theories and systemic reformulations provide some of the most compelling and enduring explanations for the development, persistence, and geographic distribution of gang behaviors. Since Thrasher’s (1927) seminal study, generations of researchers have conceived of gangs and gang behaviors as the product of social dislocations associated with urban life, including poverty, ...

This paper examines the implications of gang scheduling for generalpurpose multiprocessors. The workloads in these environments include both compute-bound parallel jobs, which often require gang scheduling, and I/O-bound jobs, which require high CPU priority to achieve interactive response times. Our results indicate that an effective interactive multiprocessor scheduler must weigh both the ben...

Given the robust positive association between gangs and crime, a better understanding of factors related to reported youth gang membership is critical and especially since youth in gangs are a universal concern. The present study investigated the role of delinquency, proactive aggression, psychopathy and behavioral school engagement in reported youth gang membership using a large sample of 1027...
