The content provided in these pages has informed the Office of Juvenile Justice and Delinquency Prevention’s FY 2010 Youth Gang Prevention and Intervention Program. While additional research needs to be done, by adapting the secondary prevention programs described herein and similar evidence-based approaches to address their local gang problems, communities can ensure a better future for their ...

Research has shown that gang membership increases the chances of offending, antisocial behaviour and drug use. 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 ...

The experience, observations, local knowledge, and historical perspective of working police officers and others with routine contact with offenders, communities, and criminal organizations may represent an important underutilized resource for describing, understanding, and crafting interventions aimed at crime problems. Mapping and other informationcollecting and -ordering techniques, usually a...

OBJECTIVE Data were collected from 270 detained male adolescents (aged 14-18 years) to determine the association between ever having been in a gang and a range of sexual behaviours such as sexual activity, male condom use, sex with multiple partners, and drug use during sex. METHODS Participants answered survey questions using audio computer assisted self interviewing (A-CASI) procedures, whi...

Objective: Is regular exercise in urban adolescents associated with decreased violence related behaviors. Methods: Cross-sectional secondary analysis of a New York City public high school survey. The exercise exposure variables identified were: Exercise frequency, # sit-ups, longest run, playing on a sports team. The violence related behavior outcome variables were: Not carrying a weapon, not b...

BACKGROUND Problems related to gangs have been noted in large cities and in many schools across the United States. This study examined the patterns of alcohol, drug use, and related exposures among male and female high school students who were gang members. METHODS Analyses were based on the Youth Violence Survey, conducted in 2004, and administered to over 80% of eligible public school stude...

Time sharing between cluster resources in a grid is a major issue in cluster and grid integration. Classical grid architecture involves a higher-level scheduler which submits non-overlapping jobs to the independent batch schedulers of each cluster of the grid. The sequentiality induced by this approach does not fit with the expected number of users and job heterogeneity of grids. Time sharing t...

Some disadvantages associated with conventional gang scheduling are that it is not scalable and that space-sharing policies are not easily incorporated to enhance the eeciency of resource utilisation due to the centralised control and the frequent signal-broadcasting across the processors. This paper describes an eeective and scal-able gang scheduling scheme and its implementation on the Fujits...
