Problem solving and youth violence: an evaluation of the Boston Gun Project

The Boston Gun Project is a problem-solving policing initiativeaimed at reducing homicide victimization among young peoplein the city of Boston. It represented an innovative partnershipbetween researchers and practitioners to assess the city's youthhomicide problem and implement an intervention intended to havepowerful impacts in the near term. In early 1996, a workinggroup representing a variety of law enforcement and social serviceagencies implemented an intervention that strategically respondedto gang violence, focused enforcement efforts on gun trafficking,and emphasized communication of the strategy to generate deterrence.The intervention is associated with a 60% decline in youth homicidevictimization (i.e., two fewer victims per month). There aresmaller declines in other measures of violence. The declinein youth homicide is sharp and occurs coincident with the introductionof the intervention. Competing hypotheses appear unable to accountfor the decline.     

postcolonial criticism,transnational identifications and the hegemonies of dancehall's academic and popular performativities

Despite the unprecedented freedoms that decolonization has brought for many Black people – especially in specific regions of the African Diaspora – freedom and its fulfilment, adequate signs and contested meanings remain a preoccupation within Black cultural discourses and practices. At the same time, while political and cultural nationalisms have led to greater political and civil rights, racism has not been eradicated. Furthermore, the new postcolonial globalizations of capital, people and cultures have destabilized the collective identities that framed twentieth-century struggles for national sovereignty and equal citizenship, without necessarily erasing them. Instead, they remain, no longer securely anchored in their old homogenous appearances, but re-configured through the inner differences and contradictions of gender, sexuality, ethnicity and religion. This article addresses these internal differences and the ways in which they produce new contestations over race, the meaning of Black representation and postcolonial freedom, negotiations that are increasingly traced on the intimate contours of the body and the self, through practices of personal consumption, erotic hedonism and style as key performances of freedom. It achieves this through examining two localized moments in the transnational and diasporic circulation of Jamaican dancehall culture, understood as a privileged public space for the performance of Black identifications and personal freedom. It argues that the eroticized discourses of ethnicity, race and gender found in dancehall culture articulate the dominance of neo-liberal conceptions of freedom at the same time as they express, resist and comment on new cultural hegemonies not reducible to racism or the power of the West; that is how dancehall expresses the new problematizations of postcoloniality.     

The effect of compressed air foam on the detection of hydrocarbon fuels in fire debris samples

In 1998/99 the New Zealand Fire Service implemented compressed air foam delivery systems for the suppression of fires in rural areas. This study investigated whether the introduction of the foam to the seat of the fire created any problems in subsequent analyses of fire debris samples. No significant interferences from the foam were found when the samples were analysed by direct headspace using activated carbon strips. The only foam component detected was limonene.
