Certain parenting behaviors have been linked with youth aggression and violence, but less is known about whether parents' attitudes toward fighting are a risk factor for children's aggressive behavior problems and future injury risk. Social cognitive theory suggests that parents' beliefs about fighting and retaliation may influence their children's attitudes toward fighting and aggression. The authors examined the associations among parental and youth attitudes toward fighting, parent-child relationships, and youth aggressive behavior in adolescents at great risk for future interpersonal violence. Data came from 72 parents and their adolescents (aged 12 to 17 years, 89% African American), who presented to an emergency department for youth's assault-related injuries. Analyses revealed an association between parents' and youth's attitudes toward fighting. Youth's and parents' attitudes were positively correlated with aggressive behavior, fighting, and school suspension. Parents' attitudes predicted youth's aggressive behavior, even after controlling for youth's attitudes. The findings suggest that interventions for high-risk youth should target the fighting-related attitudes of both parents and youth. 相似文献

Throughout North America, there has been an increasing interest in the development of alternative forums for dispute resolution that may more effectively address the needs of victims, offenders, and the community. Concurrent with this has been an attempt to alter the adversarial framework of the criminal justice system. This has included the development and implementation of case processing strategies premised on restorative justice and attempting to secure the participation of communities as partners in the resolution of disputes. One particularly innovative initiative is circle sentencing, which has been implemented in several communities in the Yukon, Canada. The procedure by which cases are processed in circle sentencing is outlined and the involvement of the offender, the victim, the community, and the territorial court are discussed. 相似文献

The field of advocacy work is growing and changing rapidly and there is much to be done in exploring not only how best to carry out effective advocacy, but also how best to use the tools of monitoring & evaluation and impact assessment (M&E/IA) to promote learning, improve accountability, and assess the value of advocacy. This paper starts by exploring the complex and changing nature of advocacy work, arguing that standardised forms of M&E/IA are likely to be inappropriate--they will probably provide misleading information, and may create perverse incentives that undermine joint action. However, while there are obvious pitfalls, there are few ready-made answers. The authors suggest that NGOs involved in advocacy at all levels should identify essential elements of their work at the outset and ensure that they monitor and evaluate those areas that they deem most important. Indeed, evidence shows that short-term successes of advocacy work may often be won at the expense of longer-term aims-- such as building capacity among partners and contributing to more fundamental change in the future. Throughout, the authors argue that an analysis of power and power structures should guide advocacy strategy and the ways in which advocacy can effectively be evaluated. A successful M&E approach must be flexible enough not only to adapt to external events, but also to be a tool for reshaping the campaign. Those of us concerned with developing M&E/IA tools for effective and accountable advocacy need to start breaking new ground. 相似文献

The U.S. government has long included in its tax code various special provisions designed to stimulate industrial R&D. In 1981, those provisions were substantially augmented by a special R&D tax credit, and various proposals are now under consideration to relax the antitrust statutes in order to encourage research through joint ventures. The case for any of these measures is difficult to establish, being based on assumptions that are not readily tested in objective terms. Nevertheless, one point is fairly clear: As between stimulating industrial R&D by individual firms and stimulating R&D joint ventures of such firms, the joint venture approach appears superior in its likely results. 相似文献

Ecological modernisation (EM) provides the principal framework within which environmental policy reform projects are understood. However, writers using the approach, neglect to explain the political contexts within which it is possible to pursue such projects. Specifically, they ignore how discourses of globalisation structure the attempts of states to introduce environmental policy measures consistent with EM agendas. Through an analysis of the UK government's attempts to introduce policies consistent with an EM approach, we show that New Labour's discourse of globalisation acts to create opportunities for EM in some policy arenas and hinder them in others. We examine the development of a renewable energy strategy, the case of genetically modified foods, and transport policy. By specifying conditions under which EM may be pursued, the analysis reveals the potential, but also the limits, of this approach, which attempts to ignore the deep political questions raised by environmental degradation. 相似文献

Hallucinogenic fungi synthesize two controlled substances, psilocin and psilocybin. Possession of the fungal species that contain these compounds is a criminal offence in North America. Some related species that are morphologically similar, do not contain the controlled substances. Therefore, unambiguous identification of fungi to the species level is critical in determining if a mushroom is illegal. We investigate a phylogenetic approach for the identification of species that contain the psychoactive compounds. We analyzed 35 North American specimens representing seven different genera of hallucinogenic and non-hallucinogenic mushrooms. We amplified and sequenced the internal transcribed spacer region of the rDNA (ITS-1) and a 5′ portion of the nuclear large ribosomal subunit of rRNA (nLSU rRNA or 28S). ITS-1 locus sequence data was highly variable and produced a phylogenetic resolution that was not consistent with morphological identifications. In contrast, the nLSU rRNA data clustered isolates from the same species and separated hallucinogen containing and non-hallucinogen containing isolates into distinct clades. With this information, we propose an approach that combines the specificity of PCR detection and the resolving power of phylogenetic analysis to efficiently and unambiguously identify hallucinogenic fungal specimens for legal purposes. 相似文献
