The current study modeled trajectories of substance use from ages 15 to 20 among 1,095 male serious juvenile offenders (M age = 16.54; 42% African-American, 34% Latino, 20% European-American, and 4% other ethnic/racial backgrounds) and prospectively predicted trajectories from risk and protective factors before and after controlling for time spent in a supervised setting. Results indicated that supervised time suppressed age-related growth in substance use. Trajectories of offenders with no supervised time and low levels of supervised time increased in substance use across age, whereas offenders with high levels of supervised time showed no growth. Almost all risk and protective factors had effects on initial substance use but only adolescent history of substance use, impulse control, and psychosocial maturity had an effect on change in substance use over time. Findings highlight the importance of formal sanctions and interventions superimposed on normal developmental processes in understanding trajectories of substance use among serious juvenile offenders.

Exposure to violence is a serious public health concern that compromises adolescents by affecting their behavior and psychological well-being. The current study advances knowledge about the consequences of exposure to violence in adolescence by applying a life course perspective to evaluate the developmental implications of adolescents’ exposure to violence. In particular, drawing on a sample of 11,949 school-aged adolescents in the U.S., we examine whether exposure to violence in adolescence is associated with precocious role exits that some adolescents experience. Exposure to violence is conceptualized as including both direct (i.e., experiencing physical victimization) and indirect exposure (i.e., witnessing others’ victimization). Three types of direct exposure to violence are examined: street, intimate partner, and family victimization, as well as four types of indirect exposure including: street, peer, and school violence as well as exposure to family/friend suicide. Using three waves of longitudinal data from the Add Health Study, we find that exposure to violence is associated with greater risks of running away from home, dropping out of high school, having a child, attempting suicide, and coming into contact with the criminal justice system in later adolescence. In addition, risks depend upon the relational context in which the exposure to violence occurred, risks increase with greater exposure to violence, and risks are, for the most part, highest for those youth exposed to both indirect and direct violence in adolescence.

The international community has had patchy success in using levers such as sanctions to end African conflicts over resources, make errant governments more accountable and ensure greater transparency in revenue management. The article highlights some of the successes and failures of the international system in this regard.  相似文献

The moral and political reverberations of the Iraq War of 2003 are still being felt all over the world. In the belligerent democracies of the West, official inquiries of all kinds and conditions have probed and exposed the nature of government, the reflexes of the national security state, and, most extraordinarily, the sensitive relations between rulers and intelligencers. For all parties the consequences have been severe. Focusing on Britain, and especially on the inquiries led by Lord Hutton and Lord Butler - an odd couple but a revelatory combination - this article takes stock of the reckoning.  相似文献
