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.  相似文献

This article explores the relationship between memory and place in understandings of urban change in Central Asia. Drawing on narratives of long-term residents of two Central Asian cities we investigate the ways in which positive memories of the Soviet past emerge when people speak about the urban environment of today. We explore why such fondness for the Soviet past has emerged, what elements of the past are most cherished, and which urban communities remember these elements. We ask what these forms of memory reveal about what has been lost and what this tells us about the present anxieties of urban residents.  相似文献

Peer victimization is a significant risk factor for a range of negative outcomes during adolescence, including depression and anxiety. Recent research has evaluated individual characteristics that heighten the risk of experiencing peer victimization. However, the role of emotional clarity, or the ability to understand one’s emotions, in being the target of peer victimization remains unclear. Thus, the present study evaluated whether deficits in emotional clarity increased the risk of experiencing peer victimization, particularly among adolescent girls, which, in turn, contributed to prospective levels of depressive and anxiety symptoms. In the present study, 355 early adolescents (ages 12–13; 53 % female; 51 % African American) who were part of the Adolescent Cognition and Emotion project completed measures of emotional clarity, depressive symptoms, and anxiety symptoms at baseline, and measures of peer victimization, depressive symptoms, and anxiety symptoms at follow-up. Moderation analyses indicated that deficits in emotional clarity predicted greater peer victimization among adolescent girls, but not adolescent boys. Moderated mediation analyses revealed that deficits in emotional clarity contributed to relational peer victimization, which, in turn, predicted prospective levels of depressive and anxiety symptoms among adolescent girls, but not boys. These findings indicate that deficits in emotional clarity represent a significant risk factor for adolescent girls to experience relational peer victimization, which, in turn, contributed to prospective levels of internalizing symptoms. Thus, prevention programs should target deficits in emotional clarity to prevent peer victimization and subsequent internalizing symptoms among adolescent girls.  相似文献

Abstract

How do governmental housing policies affect the ability of young people to exit the parental home? This paper makes three claims. First and most important, governments that create accessible and liquid mortgage markets make it easier for young people to launch from the parental home. Second, even in those countries with more liquid housing markets, younger generations today still have an increasingly difficult time realising their preferences compared to prior generations. Third, increasing income and wealth inequality interacts with housing markets to create this uneven playing field both within and across generations. This paper examines these relationships in 20 high-income OECD countries. Fewer adult children live in the parental home in countries with deep mortgage markets, high levels of social rented housing, tax relief for ownership, low buyers' transaction costs and high residential mobility. These countries cut across the traditional housing regime typologies, highlighting the need for additional housing-specific theory building.  相似文献

Recent work has begun exploring the effects of foreign military deployments on host-state foreign policies. However, research mostly focuses on dyadic relationships between major powers and host-states, ignoring the broader regional security environment of host-states. We develop a theory of spatial hierarchies to understand how security relationships throughout the region surrounding the host-state affect host-state foreign policy. Using data on US military deployments from 1950–2005, we show that regional security considerations condition how host-states respond to the deployment of military forces to their territory. Consequently, regional analyses are fundamental in understanding monadic and dyadic decisions about security, alliance behavior, and conflict.  相似文献

This study examined college students' attitudes toward spanking as a function of the situational context and age of the child. As expected, respondents were more likely to find spanking appropriate for preschool (ages 3–4) and early school age children (ages 7–8) than for older children (ages 11–12). Physical punishment was also viewed as more suitable when the child's misbehavior was disrespectful (talking back to a parent), or violated strongly held norms (hitting a playmate, stealing), and less appropriate for age-related or less serious misbehavior. Gender and race differences emerged, with males and blacks showing more support for corporal punishment than females and whites. In general, findings revealed strong support for spanking, although there was evidence of some ambivalence, especially among white and female respondents. Implications of the findings are discussed.  相似文献

Abstract: Tribometers are mechanical devices used to measure walkway coefficient of friction (COF) for the purpose of assessing slip risk. The purpose of this study was to define a tribometer reference standard and use it to assess the performance of various tribometers. Eighty subjects were randomly assigned to walk across one of four wet walkway surfaces (polished black granite, porcelain, vinyl composition tile, and ceramic tile) to establish the relative slipperiness of each surface. Eleven tribometers were subsequently used to measure and rank the COF of all four surfaces. Our results revealed that only four of the 11 tribometers (Wessex pendulum, Sigler pendulum, Mark II, and Mark III) met our compliance criteria by both correctly ranking all four surfaces and differentiating between surfaces of varying degrees of slipperiness. Our protocol demonstrates that human gait‐based measures of slipperiness can be used to create reference standards against which tribometer measurements can be validated.  相似文献
