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...

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 ...

Multi-armed bandit problems formalize the exploration-exploitation trade-offs arising in several industrially relevant applications, such as online advertisement and, more generally, recommendation systems. In many cases, however, these applications have a strong social component, whose integration in the bandit algorithm could lead to a dramatic performance increase. For instance, content may ...
