The prevalence of Clonorchis sinensis metacercariae (CsMc) was examined in freshwater fish from the water systems of Seomjin-gang (River), the Republic of Korea. Total 1,604 fish from 7 local sites of Seomjin-gang were examined by artificial digestion methods. The metacercariae of C. sinensis were detected in 102 (39.8%) out of 256 fish (14 species) from the upper reaches of Seomjin-gang, i.e.,...

This article discerns the role that Mexican American gang members play in drug markets, and the relationship between gang members'drug use and drug selling in South Texas. A four-part typology based on the two dimensions of gang type and gang member emerged from this qualitative analysis of 160 male gang members: Homeboys, Hustlers, Slangers, and Ballers. Major findings include the following: (...

BACKGROUND Three different explanations have been given for the observation that adolescent gang members report more delinquent behaviour than their counterparts who do not affiliate with gangs: a) adolescents who commit more crimes join gangs (selection hypothesis); b) gang membership facilitates deviant behaviour (facilitation hypothesis); c) selection and facilitation work interactively (enh...

The aim of this study was to examine whether street gang membership, psychological factors, and social factors such as preprison experiences could predict young offenders' involvement in prison gang activity. Data were collected via individual interviews with 188 young offenders held in a Young Offenders Institution in the United Kingdom. Results showed that psychological factors such as the va...

In this paper we propose a new class of scheduling policies, dubbed Concurrent Gang, that combines the advantages of gang scheduling for communication and synchronization intensive parallel jobs with the flexibility of a Unix scheduler for sequential and I/O intensive jobs. Besides that, scalability in Concurrent Gang is achieved through the use of a global synchronizer that coordinates the gan...

Pseudo gangs form the steely side of Hearts and Minds and were used with great effect in counter-insurgency campaigns in Kenya (1952-60) Malaya (1948-60) and Rhodesia (1964-1979). Although the use of pseudo gangs was not new to counter-insurgency tactics, with the British using a similar tactic in the Boer war (1899-1902), the use of such gangs was certainly perfected during these later campaig...

Most of the empirical research and practically all of the fieldwork conducted on gangs has been devoted to street gangs. In this paper, automated data from the Bureau of Prisons were used to evaluate the contribution of prison gang affiliation to violent and other forms of misconduct within the institution. We also examined a measure of gang embeddedness to see if, similar to the street gang re...

Gang scheduling has been widely used as a practical solution to the dynamic parallel job scheduling problem. Parallel tasks of a job are scheduled for simultaneous execution on a partition of a parallel computer. Gang Scheduling has many advantages, such as responsiveness, efficient sharing of resources and ease of programming. However, there are two major problems associated with gang scheduli...
