Although physical punishment has been studied for decades, there are gaps in the literature regarding frequently used form, context, and cross cultural differences. A comparison was made using 227 college students in the United States and Japan, who were presented with four scenarios and surveyed regarding attitudes toward physical punishment, perceptions of appropriate discipline methods, and past experience with physical punishment. Japanese and U.S. respondents reported similar personal experience with physical punishment (Japanese 86%, U.S. 91%). However, U.S. respondents reported a higher likelihood of being hit with an object than did Japanese respondents. For U.S. respondents, the bottom and the hand were the top two sites on the body used for physical punishment, whereas the head and the face were the top two places for the Japanese sample. Unlike U.S. respondents, type of child misbehavior was found to have an impact on Japanese respondents’ views on the appropriate discipline method. 相似文献

What does the injunction “serve the public interest” really mean for public managers, and why is it important? By way of an answer, this analysis systematizes different perspectives on the public interest and offers a multifaceted formulation of the public manager’s duty. It is a process involving the exploration of two concerns—democracy and mutuality—in the current time frame and two others—sustainability and legacy—in the future time frame. 相似文献

在合理配置国家资源条件下,使用指示性计划的国际经验表明,指示性计划必须结各国具体的经济、社会和政治情况。俄罗斯在融入全球化的过程中,需要建立起符合自身条件的市场机制,处理好全球化进程中俄罗斯国民税收体系改革和人力资本问题,从而使俄罗斯摆脱沦为西方发达国家原材料提供者的危险境地。要建成国家投资和创新的发展模式,走上可持续增长的轨道,并将居民的生活质量提高到一个新的水平,从战略的角度考虑,俄罗斯需要提高国家在社会经济发展中的作用,建立起社会取向型国家的劳动和社会福利关系。 相似文献

Abstract: In the increasingly complex and “horizontal” environment of Canadian governmental decision‐making, the ability of governments to advance a major new policy initiative can be compromised or impeded by the often cumbersome systems evolved to ensure both due diligence and a comprehensive approach. In Ontario, the urgent and multi‐faceted health care reform agenda has been implemented using a new set of policy‐development and program‐implementation techniques. This paper summarizes those reforms. In doing so, it outlines the degree to which the reform agenda has been implemented using techniques and processes that have been grafted onto or even short circuited existing decision‐making systems. The paper also draws conclusions about the potential utility of the Ontario experience both for health care reform and for developing new mechanisms to implement challenging, time‐limited reform agendas within parliamentary systems of government with politically neutral civil services. Sommaire: Dans le contexte de plus en plus complexe et “horizontal” de la prise de décisions gouvernementale au Canada, l'aptitude des gouvernements à promouvoir une nouvelle initiative politique majeure peut être compromise ou entravée par la lourdeur des systèmes élaborés pour assurer une diligence raisonnable et une approche exhaustive. En Ontario, le programme de réforme des soins de santé, urgent et polyvalent, a été mis en œuvre grâce à un nouvel ensemble de techniques d‘élaboration de politiques et de mise en œuvre de programmes. Le présent article résume ces réformes. Ce faisant, il souligne comment le programme de réforme a été mis en œuvre grâce à des techniques et processus qui ont été greffés, ou qui ont même court‐circuité les systèmes de prise de décisions existants. L'article tire aussi des conclusions sur l'utilité possible de l'expérience de l'Ontario en ce qui concerne la réforme des soins de santé mais aussi la mise au point de nouveaux mécanismes pour exécuter des programmes de réforme difficiles, à délai déterminé, au sein de systèmes parlementaires de gouvernement avec des fonctions civiles politiquement neutres. 相似文献

Correctional facilities are increasingly burdened with mentally disordered offenders and are faced with the formidable task of effectively screening inmates for major mental disorders and suicide potential. Teplin and Swartz (1989) developed the Referral Decision Scale (RDS) as a rapid screen for schizophrenia and major mood disorders in jail populations. However, more recent research by Hart, Roesch, Corrado, and Cox (1993) has called into question the effectiveness of the RDS. In this study, we examined the convergent and discriminant validity of the RDS with the Schedule of Affective Disorders and Schizophrenia—Change Version (SADS-C) and the Personality Assessment Inventory (PAI) on a sample of 108 mentally disordered inmates. The RDS provided moderate evidence of convergent validity but failed to demonstrate acceptable discriminant validity, because of high intercorrelations on RDS subscales (heterotrait-monomethod coefficients). In comparison, the SADS-C yielded similar evidence of convergent validity and excellent discriminant validity.The authors would like to thank the Research Opportunities Program, University of North Texas for its grant support and Captain James Moore for his active cooperation.Tarrant County Mental Health and Mental Retardation Services. 相似文献

The fingernail ridge patterns of a pair of identical twins were compared to each other, their parents, and an unrelated subject. The patterns of the twins' nails showed regions of strong similarity but were distinguishable from one another. Fewer similarities were found when comparing the nails to those of the parents and the unrelated control. The twins were shown to be monozygotic by means of DNA profiling. This therefore represents the first demonstration of unique fingernail ridge patterns in subjects shown conclusively to be identical twins. When the fingernail ridge patterns were examined with a scanning electron microscope, the backscattered electron (BEI) images were found to have superior contrast when compared to the secondary electron (SEI) images. 相似文献
