Little documentation exists regarding the functioning of formalized adolescent groups as drug abuse prevention agents. Two studies are described that were conducted at high schools whose students are at high risk for drug abuse. Twenty-one schools were randomly assigned to one of three conditions: (a) standard care, (b) classroom drug abuse education only, or (c) classroom plus school-as-community. Results of the first study indicated that the school-as-community component--which involved weekly meetings and periodic events at seven schools--was implemented as planned, drug abused focused, and perceived as productive in discouraging drug abuse. In the second study, staff in the classroom plus school-as-community condition self-reported involvement in the greatest number of community activities across the school year, compared with staff from the other two conditions. These two studies support the feasibility of formalized groups of high-risk youth to promote drug-free events.  相似文献

A review of the way physician-assisted suicide (PAS) is being addressed in the United States reveals three models, each functioning out of distinctive concepts of autonomy: (1) litigation, which utilizes philosophical autonomy; (2) legislation, which utilizes political autonomy; and (3) act of conscience by a physician, which utilizes consumer autonomy. Each model raises a correspondingly distinct set of ethical questions and challenges centered around their point of reference-the judicial system, voters, or the doctor-patient relationship. In the end, however, efforts to resolve the challenge of PAS will falter if they do not go beyond these models of autonomy. Religious institutions offer a more constructive setting for facing the life and death decisionmaking of PAS. The challenge for religion is to address PAS in solidarity with sufferers, physicians, and the community, rather than retreating into iconoclastic dogmas.  相似文献

"This study is based upon an international dataset comparing state support for families in fifteen countries (of which twelve are member states of the European Union).... Using multiple regression analysis, the levels of state support are explained by the principal parameters used for setting the levels of benefit, and by the demographic and economic characteristics of the countries concerned....[Results suggest] that the economic convergence of the member states is likely to promote greater similarity in their systems of state welfare support for families."

The maximum likelihood estimation for the critical points of the failure rate and the mean residual life function are presented in the case of mixture inverse Gaussian model. Several important data sets are analyzed from this point of view. For each of the data sets, Bootstrapping is used to construct confidence intervals of the critical points.  相似文献

US theoretical models of assimilation of ethnic groups within a larger culture usually assume a unilinear, unidimensional process, which is simplistic, does not account for the persistence of ethnicity, and oversimplifies the process of social change. The argument is advanced that ethnic identity is both primordial and situational (a private sense that is self-maintaining, cumulative, deepening, and self-affirming). Typically, a person has one primary ethnic identity, but where ethnic boundaries overlap, there is instrumental identity. Chinese in Thailand mostly adopt Thai values, speak the Thai language, go to Thai schools, join Thai associations, and celebrate Thai religious festivals. Their secondary identity as Chinese is integrated into their associations with other Chinese and in the home through the use of the Chinese language. Their Chinese identity appears also in ancestor worship. There are symbiotic relationships between native Thais and Chinese Thais along class lines. The Chinese are known to have great financial and economic resources, while the Thais have political and administrative control. These differences with the power elites separate the Chinese from the Thais and interfere with assimilation. The power is balanced. If the Chinese gained in political and administrative power, the balance would be upset, and the interests of both groups would be threatened. The view of Whitten and Whitten acknowledges that individuals and groups act to make the best of the situation and are not merely victims of social forces. Actions are maintained and resisted. The important consideration in theory-building is not the terms of assimilation but the terms specifying the conduct of the group as a whole and as individuals in daily social interactions. The theoretical discussion focuses on border crossings, the Skinner view of the Chinese, bilingualism and cultural education, socioeconomic organizations, occupational differences, and religion, tradition, and ethnic identification.  相似文献

This paper illustrates the role of supervision in processing countertransference responses with might have disrupted the therapist's empathy with a patient who had killed her child. The clinical material demonstrates how the therapist's responses of initial denial and subsequent disgust and fear were dealt with in supervision. As a result, the treatment process led to genuine, albeit limited, therapeutic change in a patient with severe character pathology.This paper is developed from a presentation of the case of Mrs. Jay at Department of Psychiatry Grand Rounds, University of Cincinnati College of Medicine, on May 2, 1989.  相似文献
