This study examines a crucial question: What kind of effect do interdiction and other drug enforcement activities have on drug smuggling? Do they actually deter smuggling, or is their effect more one of disruption and displacement?...  相似文献

For the past 5 years in the United States, there has been an increased emphasis on evidence-based programs, and, in particular, the promotion of experimental designs as the highest standard of evidence. This interest has been fueled by the Federal government's demand for accountability that links budget allocation with program performance. The National Institute of Justice, the research, development and evaluation agency within the Office of Programs in the U.S. Department of Justice is undertaking a number of efforts to improve the quality of evaluation research and address the need for evidence-based programs. These efforts have focused on making improvements upfront in the grant selection process so that well-designed evaluations will be undertaken and in the management and monitoring of ongoing evaluation research grants so that implementation and design issues can be identified and addressed. Evaluability assessments is a key strategy that NIJ is relying on increasingly to identify programs that have a high likelihood of being successfully evaluated. Whether these efforts will lead to an overall increase in the rigor of NIJ-supported evaluations remains unanswered at this time. The views expressed are those of the authors and not necessarily those of The National Academies or the National Institute of Justice.  相似文献

Abstract. The factors underlying patterns of partisan preference in Greece have been the subject of fairly little systematic analysis. This article uses data from a 1980 Euro-Barometer survey, the first to include a Greek sample, to outline the structure of the Greek partisan universe. A number of demographic variables – age, family income, education, occupation, sex, size of community, and household status – together with attitudinal variables regarding both foreign and domestic policy issues are tested as predictors of party identification. The multivariate statistical technique of discriminant analysis is used to measure the relative importance of these predictor variables in influencing the direction of party preferences. The findings show that attitudinal factors for the most part are more important than demographic traits. A stepwise analysis provides a rankordering of the strongest explanatory variables. The impact of recent political and historical developments on the party system in Greece is discussed.  相似文献

Self-esteem and psychological symptoms were assessed in a sample of 1082 Chinese adolescents who responded to the Chinese versions of Coopersmith's Self-Esteem Inventory and the General Health Questionnaire. Three dimensions of self-esteem, interpreted as Family Acceptance/Rejection, Self-Depreciation, and Peer Affirmation/Disaffirmation, were found to relate substantially to general psychological symptoms and particularly to specific symptoms of anxiety, social dysfunction, and depression as reported by these adolescents. The implications of the relative importance of appraisal from internal feedback as sources of self-esteem as opposed to the external feedback from family and peers were discussed in relation to self-esteem enhancement in adolescents.Received his Ph.D. from the University of Western Ontario in 1978.

A cultural tradition to acknowledge a girl's first menstrual period is proposed in order to overcome the negative connotation of the event. Three basic questions regarding such a tradition are addressed: Who would participate? What would it mean? What type of activity should it be? A research team consisting of a psychologist, a nurse, and a social worker suggests answers based on their interviews with mothers and daughters, as well as their collection of menarche anecdotes from women psychologists.  相似文献
