Drug abuse is an enormous public health problem with consequences not only for individuals using drugs but also for families, communities, and society. Moreover, research evidence and clinical experience agree that drug abuse is one of the more difficult problems to treat. Despite considerable research on the connection between family factors and drug use, and the existence of family therapy models for drug abuse, comparatively few controlled efficacy studies have been conducted. This article presents a critical review of controlled treatment outcome research in the area of family therapy for drug abuse in both adults and adolescents. A number of studies from different clinical research groups demonstrate that different versions of family intevention can engage and retain drug users and their families in treatment, significantly reduce drug use and other related problem behaviors, and enhace particular domains of prosocial functioning. Moreover, a smaller number of comparative efficacy studies have shown family therapy to be more effective than nonfamily therapies. Family therapy of adolescent drug abuse is more developed at present than family therapy of adult drug abuse. Although the results of the reviewed studies are promising, a blanket confirmation of family therapy's efficacy for drug abuse cannot be made at this time because of the relatively small number of studies and the noted methodological limitations of the studies published to date. Nonetheless, substantial progress in this clinical research area has occurred, and if research and funding support continue or can expand, significant breakthroughs in the treamtment of drug abuse with family-based treatments are possible. 相似文献

There is a considerable literature on transfer pricing. One strand of this literature is empirical and is concerned with the extent to which companies use the various transfer pricing methods. The other strand is strongly normative being directed to devising transfer pricing methods and defining the circumstances under which it is appropriate to use them. This study attempts to address both these questions by using discriminant analysis methods to predict which approach a company will use to determine transfer prices given its weightings of certain ‘determinants’ which theory suggests should be relevant to the decision. Domestic and international transfer pricing are considered separately. Discriminant analysis is shown to be quite successful in predicting the transfer pricing systems adopted by the UK companies surveyed. 相似文献

The most serious problem facing the United States, accordingto many scientific and political leaders, is the threat of nuclearwar. Yet the standard survey question on the most importantproblem facing the country has often shown little public concurrencewith this assumption. Our article uses experimentation in nationalsamples to test whether this difference can be traced to limitationsin either the form or the wording of the standard question.The results indicate that there are some important systematicdifferences between open and closed versions of the question,and also differences that result from reference to the nationas distinct from the world, but neither type of difference accountsfor the infrequent mention of nuclear war on the standard question.Instead, other evidence indicates that most Americans believethat nuclear war is not going to happen at all, or that if itdoes happen it will be too far in the distant future to be ofpressing concern to them personally. 相似文献

Current discussions within symbolic interaction point to a concern with (a) returning to Mead's original insights, (b) extending Meadian thought beyond the micro realm, and (c) linking Mead's ideas to constructive social action. These concerns complement an effort within contemporary Marxist literature to provide a systematic social psychology for understanding new forms of domination in capitalist society. In exploring the philosophical foundations of Mead and Marx, the authors identify fundamental similarities in their approaches to the relation between consciousness and community. The authors criticize the current attempts to synthesize Marx and Freud and call for a more thoroughly sociological approach. A Meadian reading of Marx, unlike the Marx-Freud synthesis, is consistent with sociological assumptions and points to the practical possibility of transformative social change through the interpersonal act. 相似文献

Hazardous waste policy in the United States uses a liability-based approach, including strict, retroactive, and joint and several liability. To assess attitudes toward these basic principles of liability, and toward priorities for clean-up of wastes, a questionnaire was mailed to legislators, judges, executives of oil and chemical companies, environmentalists, and economists. The questionnaire consisted of abstract, simplified cases, which contrasted basic principles rather than dealing with real-world scenarios. Subjects were asked how they would allocate clean-up costs between companies and government as a function of such factors as adherence to standards, adoption of best available technology (BAT), and influence of penalties on future behavior. Most subjects felt that, if the company followed government standards or used the best available technology (BAT), it should pay for only a portion of the clean-up cost, with the government paying the rest. In general, responses did not support the principles underlying current law–strict, retroactive, and joint-and-several liability. Most subjects were more interested in polluters paying for damages than in deterrence or future benefit–even to the extent that they would have "harmless" waste sites cleaned up. A bias was found toward complete clean-up of some sites, or "zero risk." Different groups of subjects gave similar answers, although more committed environmentalists were more willing to make companies pay and to clean up waste regardless of the cost. 相似文献

Methods based on scan statistics are widely used in health-related applications to detect clusters of disease. The most common methods are based on the Bernoulli and Poisson models. Kulldorff (1997) derived the likelihood ratio test statistic for his scan method for both of these models. His scan statistic is widely used with freely available software, SaTScan? (see Kulldorff, 2005). We provide an alternative derivation of the likelihood ratio test statistic in the Poisson case. Our derivation is simpler and more general in the sense that it applies when the incidences are not aggregated into subregional counts. 相似文献

The method of estimated generalized least squares estimation of multiple response models is extended to the randomly missing date case. This estimation procedure is computationally simply when there are many missing data but the number of distinct patterns of missing data for the response vectors is small. The consistency and asymptotic normality of the proposed estimators are established. 相似文献
