This paper argues that the EuropeanCourt of Human Rights couldserve as a model for an international court ofhuman rights to be builtupon the United Nations Committee on HumanRights. It argues that theconcerns states might have over the surrenderof a significant portion oftheir national sovereignity might be lessenedif such an internationalcourt were to incorporate the margin ofappreciation doctrine employed bythe European Court of Human Rights. Thisdoctrine is intended to respectthe customs and traditions of sovereign statesin dealing with humanrights issues, while maintaining that somerights such as the right not tobe tortured will be considered as basic andwill stand independently ofthe customs and traditions of sovereignstates.  相似文献

中学生厌学心理及其干预与学习效率的相关研究   总被引:17,自引:1,他引:16  
本研究旨在考察两个问题:1.心理咨询是否是改变中学生厌学心理的有效途径,如果是,它能够在多大程度上改变厌学心理;2.厌学心理的改善能否有效提高中学生学习效率。本实验用问卷调查法从183名中学生中筛选出有厌学心理的学生24名。运用个体心理咨询、团体心理咨询等手段对这24名学生进行为期4个月干预、结果表明:心理咨询能够有效且明显地改善厌学心理。但要完全消除厌学心理则还需要辅以其他干预手段;随着学生厌学心理的改善,其学习效率也相应有了明显的提高。  相似文献

The prevalence of being a victim of harassment or stalking among the general population of the UK is held to be 11.8 per cent. There has been speculation that the prevalence rate would be higher for psychological therapists, as they could be at risk from their own clients. This study analysed the prevalence of job‐related experiences of harassment or stalking in a postal survey of psychological therapists who worked in primary care. The results showed a prevalence rate of more than twice the national average at 24 per cent. The stalkers, who were equally male or female, fell into three broad categories: those clients who were needy and made early attachments to their therapists; those experiencing erotic transference; and those with personality disorders. The implications of these findings for training and practice are discussed.  相似文献

The growth of child and adolescent psychiatric services based on the wraparound philosophy raises new questions for medical directors, investigators, and clinicians interested in improving quality of care and outcomes. Typically, quality improvement studies have focused on standardizing care and decreasing variation while community based services following a wraparound model are by definition individualized. To date, little information on how to evaluate such services in a managed care environment has been available. We present one option for evaluating the distribution of medical services and the extent to which providers individualize services for children with severe emotional disorders. Specifically, we (a) review the philosophy and goals of wraparound services, (b) introduce the Lorenz curve as a tool for determining the degree of inequality in service distribution at a given institution, and (c) present a case study on the use of Lorenz curves by a Medicaid Behavioral Health Organization in profiling behavioral providers.  相似文献

We examined Treatment Foster Care (TFC) in residential trajectories for youth with psychiatric disorders and aggressive behavior. We analyzed residential placements of a statewide sample of youth during the 12 months preceding and following admission to TFC. Prior to TFC, the majority of youth were residing in more restrictive settings (group homes or residential treatment). Two-thirds of youth remained in TFC throughout the follow-up year. Of those who left, nearly half returned home, and slightly fewer were discharged to group homes. By the end of the 12-month follow-up period, rates of group home use were similar to those seen in the pre-TFC period. Movement out of TFC during the year was associated with being older at placement and with increased problem behavior (particularly externalizing behaviors). TFC serves as a step-down placement for a substantial number of youth. However, this is not the only way it is used, and models based on short-term transitioning or reunification with families may not be widely implemented or relevant in practice. Additional research is needed to understand current functions of TFC in residential trajectories and to maximize its utility in systems of care.  相似文献

Genetic counseling in Australasia (Australia and New Zealand) has been recognized as a profession since the 1980s and has steadily expanded over the past 20 years. The demography of major cities with metropolitan sprawl and sparsely populated rural areas has led to the establishment of 3 types of genetics units: main units in cities, metropolitan outreach, and rural outreach units. A questionnaire was developed to obtain information about the needs, resources, and day-to-day operation of the genetic counselors. The questionnaire addressed the areas of resource availability, professional development, responsibility of genetic counselors in the clinical setting, and their involvement in promotion of the service and public education. Differences observed between the 3 settings in all of these areas included large clinical loads for metropolitan outreach counselors, varying responsibilities in the clinical setting, and a lack of support and resources for rural outreach counselors. Australasian Genetic counselors were found to have a significant interest in developing mechanisms for supervision and were keenly interested in maintaining credentials and professional role development. The results of this study allows genetic counselors themselves to have a better understanding of the roles of their colleagues in the different units; they can also be used by service providers in establishing and supporting genetic counselors, and identifying inequalities and deficiencies in the different practice areas.  相似文献
