The long-term effectiveness of Drug Abuse Resistance Education (D.A.R.E.) was assessed by contrasting drug use and other D.A.R.E.-related attitudinal latent variables among 356 twelfth-grade students who had received the program in the 6th grade with 264 others who did not receive it. A prior study of these subjects when they were in 9th grade had shown no significant differences. A follow-up survey in 12th grade assessed central D.A.R.E. concepts such as self-esteem, police bonds, delay of experimentation with drugs, and various forms of drug use. Although the authors found no relationship between prior D.A.R.E. participation and later alcohol use, cigarette smoking, or marijuana use in 12th grade, there was a significant relationship between earlier D.A.R.E. participation and less use of illegal, more deviant drugs (e.g., inhalants, cocaine, LSD) in a development sample but not in a validation sample. Findings from the two studies suggest a possible sleeper effect for D.A.R.E. in reference to the use of harder drugs, especially among teenage males.  相似文献

This paper presents three different poverty standards. A first approach takes the disposable income as an indicator of poverty. A second approach uses the Leyden approach. Finally an aggregate index of deprivation, based on the observation of consumption events, is constructed through a particular econometric procedure proposed by Desai and Shah (1988). These alternative measures are then compared on a sample composed of 6380 Belgian households. Such an analysis can be expected to provide some further insight into the problem of measuring poverty, which has been the subject of a recent controversial debate.We thank the participants of the Second Annual Meeting of the European Society for Population Economics, June 23–25, 1988, Mannheim (FRG), L.

The author discusses "the likely scale of in-migration from the other former union republics into the Russian Republic over the remainder of this decade....I believe that during the 1990s there will be continued mass in-migration into Russia from the seven former union republics of Central Asia and the Transcaucasus....I also foresee that Russians will continue to leave such inhospitable milieux as southern Kazakhstan and western Ukraine."  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

Abstract Extract In their recent paper in this journal M. and Carol Vlassoff are to be commended for helping to remedy the dearth of empirical studies on the old-age security motive for children (and particularly sons) in rural areas of developing countries.(1) However, while the questionnaire which they applied to 357 ever-married men in a rural village in Maharashtra state in India is potentially useful, several of the conclusions they derive from it are unwarranted and, if left unquestioned, would undoubtedly have the effect of setting back the serious investigation of the effects of this motive rather than furthering it. The invalid or at least questionable inferences are taken up one at a time in the order of their appearance:  相似文献

In this article the author argues that more formality in social responsibility planning efforts is a concept which is extremely pertinent in today's conditions. Rewards will accrue to the organization that can move beyond aesthetic objectives and achieve operationality in social responsibility goal setting. This requires, basically, the application of techniques that have proved to be successful in MBO programs. By translating broadly stated social objectives into goals that are clear, concise, time related and cost related, management will inject an increased measure of integrity into its planning process, improve social responsibility programs, assure future successes in the social performance arena, facilitate the appraisal of management personnel, and enhance the organization's credibility with its multiple publics. Positive benefits will flow to the organization, its immediate publics, and to the society at large as a consequence of operational planning methods as described herein.  相似文献

The client oriented cost outcome system has been under development in Pennsylvania community and hospital programs since 1972. The system builds upon the behavioral and decision data generated with or on behalf of consumers. Flexibility for local program system design is permitted if the procedures of consumer intake, review, and termination document each consumer's (a) problems, resources, and goals, (b) overall functioning level in their ordinary community, and (c) services intended and rendered as related to (a), above. While the system's primary application is in providing feedback for local program quality assurance and evaluation procedures, aggregation of data permits program planning and evaluation at county, state, and federal levels in terms of (a) client demographic or diagnostic characteristics, and (b) program service characteristics and objectives.  相似文献
