We deene the bounds of two gang service algorithms, namely time balanced and instruction balanced, using interactivity and throughput based metrics. The work-load is composed of V-RAM jobs, and the architectural model chosen is LogP. We also analyze the eeect of workload and space sharing strategies on the bounds found. The following results are demonstrated: when inter-activity is considered, ...

The goal of this paper is to determine how e ciently we can implement an adequate parallel programming environment on a workstation cluster without modifying the existing operating system. We have implemented a runtime environment for parallel programs and gang-scheduling on a workstation cluster. In this paper, we report the techniques used to implement gang-scheduling on a workstation cluster...

Many urban environments have criminal gangs competing for control of available resources and gang territories. Research in criminology has linked the effect of these gang territories on criminal activity by criminal gangs. However, a great deal of a given criminal group’s activity occurs beyond the boundaries of that gang’s known territory but within a region we term a gang’s criminal sphere of...

OBJECTIVE To examine the association between gang involvement and female adolescents' health. METHODS African American adolescent females (N = 522) completed a survey that assessed their history of gang involvement and health behaviors and provided specimens that were analyzed for marijuana use and sexually transmitted diseases. RESULTS In logistic regression analyses, adolescents with a hi...

Gang youth are at an increased likelihood of participating in unsafe sexual behaviors and at an elevated risk of exposure to sexually transmitted infection (STIs), including HIV. This manuscript presents quantitative and qualitative data on sexual behaviors among a sample of predominately heterosexual, male gang youth aged 16 to 25 years interviewed in Los Angeles between 2006 and 2007 (n = 60)...

We examined condom attitudes, perceived vulnerability to HIV, HIV testing experiences, and sexual and substance use risk behaviors of 161 active Latino male gang members, aged 18-26 years old, living in Los Angeles, California. Gang members reported negative condom attitudes and a perceived vulnerability to HIV. The majority (53%) of gang members reported unprotected vaginal intercourse (UVI) i...

Gang affiliates have joined the masses who use social media to share thoughts and actions publicly. Interestingly, they use this public medium to express recent illegal actions, to intimidate others, and to share outrageous images and statements. Agencies able to unearth these profiles may thus be able to anticipate, stop, or hasten the investigation of gang-related crimes. This paper investiga...

This research focuses on young Mexican American girls who are not formal gang members yet participate in street-based activities of male gangs and engage in risk behaviors. These females comprise a larger proportion associated with male gangs in inner-city neighborhoods than actual female gang members. Using a qualitative design, the article presents a typology of Mexican American females that ...

OBJECTIVE To estimate the effects on homicide rates of the gang truce that was brokered in El Salvador in 2012. METHODS Mathematical models based on municipal-level census, crime and gang-intelligence data were used to estimate the effect of the truce on homicide rates. One model estimated the overall effect after accounting for the linear trend and seasonality in the homicide rate. In a mode...
