Peer victimization is a common problem among adolescents that has been linked to a variety of adjustment problems. Youth involved in peer victimization represent a heterogeneous group who may differ not only in their levels of victimization and perpetration, but also in the factors that influence their behavior. The current study used latent class analysis (LCA) to identify subgroups of aggressive and victimized youth, and to examine social-cognitive and environmental factors that differ across these subgroups. Participants were a predominantly African-American (i.e., 68 %) sample of 502 sixth, seventh, and eighth graders (45 % male, Mean age = 12.6 years) attending three urban public middle schools, who completed self-report measures of aggression, victimization, and associated individual and contextual factors. LCA identified four classes of adolescents representing non-victimized aggressors, aggressive-victims, predominantly victimized youth, and well-adjusted youth. Class differences were found on measures of beliefs supporting fighting, beliefs against fighting, perceived effectiveness of inept nonviolent responses to conflict, behavioral intentions to engage in aggressive and nonviolent behavior, self-efficacy for nonviolent behavior, and peer and parental support for aggression and nonviolence. For example, within the two classes of victimized youth, aggressive-victims reported greater intentions to engage in physical aggression and inept nonviolent behavior, and were more likely to agree with beliefs supporting the use of instrumental and reactive aggression, and beliefs that fighting is sometimes necessary compared to predominantly victimized youth. These findings emphasize the importance of developing preventive interventions that target the specific needs of distinct subgroups of adolescents.  相似文献

There are high expectations that the HIH Royal Commission will uncover the truth about the collapse of the HIH insurance group and bring to justice the individuals and organistions culpable for the losses incurred. This article argues that this hope for veracity flies in the face of other royal commissions into financial issues in Australia which were but verisimilitude.  相似文献

The 1980s have seen the triumph of economic rationalism. Greater efficiency has become a sacred goal. Increased competition and the unlocking of market forces, we are told, are the key means to obtain it. Proponents of economic rationalism insist that the public sector is riddled with inefficiencies. The private sector, by contrast, is self-evidently superior. To the extent that the private sector often operates less than optimally, a major reason is the plethora of perverse governmental regulations which hamper its efficiency. Despite the problems, the public sector needs to model itself wherever possible on the private. And where public sector activities can be or are being done in the private sector, then the public sector should surrender such activities. The inevitable result will be an increase in net economic welfare: the economy will become more dynamic and scarce resources will be allocated more efficiently. Such is the rhetoric of the economic rationalists.  相似文献

In commenting on the ANOP survey, I have not attempted to investigate its validity. The results are taken at face value as representative of the populace as a whole.  相似文献

Previous self-harm has been identified as a risk factor for subsequent suicide by adolescents. The objective of the study was to identify further risk factors for subsequent premature death and suicide in a population of adolescents presenting with self-poisoning. A longitudinal cohort design using data-linkage of consecutive adolescent patients presenting to the Hunter Area Toxicology Service, a regional toxicology service for Newcastle, Australia, with the National Death Index of the Australian Institute of Health and Welfare was used. A total of 441 adolescents aged 10 to 19 years presented with self-poisoning over 5 years from January 1991 to December 1995, with follow-up to March 2001. There were 14 deaths total, eight of which were likely suicides. There was a 22-fold increase in suicide rate for males and a 14-fold increase for females compared with age-normalized population rates. Adjusted hazard ratios (95% CI) forpremature death were male gender 3.77 (1.11-12.78), nonaffective psychotic disorders 16.3 (3.83-69.34) and the mental illnesses of childhood 6.12 (1.68-22.23). There was a similar pattern for suicide: Male gender, nonaffective psychotic disorders, and the mental illnesses of childhood confer greater risk for subsequent suicide or premature death in this population.  相似文献

Political mechanisms of accountability were marginalized by Conservative government reforms during the 1980s and 1990s which sought a more market-oriented approach within the public sector in order to enhance ‘consumerism’. In education, parents were given more choice between schools and were provided with more information on school performance. The promotion of market accountability has involved a reduction in the powers of local education authorities (LEAs) which had been central to the operation of political accountability. However, whilst market-based forms of accountability were firmly enhanced in principle by the legislation, to what extent have the forms of accountability operating within LEAs changed in practice? Interviews with Chief Officers and the Chair of the Education Committee are used to identify changing perceptions and practices of accountability in LEAs in Wales. The findings indicate that although local politicians and officials have been forced to operate within the legislative framework of market accountability, they have sought to impede its successful implementation. The policy community in Wales facilitated the LEAs’ capacity to respond in this way. The market-based reforms conflicted with fundamental values held in Wales, which remain those of professional accountability.  相似文献
