Gang scheduling is an approach for resource allocation in parallel and distributed systems that combines time-sharing with space-sharing to ensure a short response time for interactive tasks and high overall system throughput. In this paper, we present queueing theoretic models for a particular gang scheduling system under a workload representative of large-scale engineering and scientiic compu...

Gang scheduling is currently the most popular scheduling scheme for parallel processing in a time shared environment. In this paper we first describe the ideas of job re-packing and workload tree for efficiently allocating resources to enhance the performance of gang scheduling. We then present some experimental results obtained by implementing four different resource allocation schemes. These ...

Prison gangs disrupt correctional programming, threaten the safety of inmates and staff, and erode institutional quality of life. The authors review the history of, and correctional mechanisms to cope with prison gangs. A suppression strat...

■ Abstract This review discusses research on the urban street gang after the 1960s, the period in which social scientists began to conceptualize the gang outside of the social-problems framework. Street-gang research has changed dramatically in the past three decades in accordance with general shifts in sociological research, including developments in gender studies, economic sociology, and rac...

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. Specifically, law enforcement accounts typically suggest higher levels of cohesion than do investigations relying on interviews with or observations of street gang members. It is possible ...

Dynamic activity involving social networks often has distinctive temporal patterns that can be exploited in situations involving incomplete information. Gang rivalry networks in particular show a high degree of temporal clustering of activity associated with retaliatory behavior. A recent study of a Los Angeles gang network shows that known gang activity between rivals can be modeled as a self-...

Women and violence has become a topic of increasing concern. Women's involvement in perpetrating violence, especially girl gang members, also has raised national concern. The participation of young women in gangs and gang violence has caused public consternation as they are perceived to be violating traditional notions of femininity. In spite of this increased concern and burgeoning literature,...
