InMaryland v. Craig, the United States Supreme Court relied heavily on a brief prepared by a committee of the American Psychology-Law Society on behalf of the American Psychological Association (APA). The APA brief concluded that sexually abused children may be particularly vulnerable to distress in the legal process, especially when forced to confront the defendant face to face, and that such acute distress may be inconsistent with the state's interests in promotion of reliable testimony and child welfare. APA also argued that psychological theory and research provide foundations for individualized determination of the need for measures to protect children from face-to-face confrontation. *** DIRECT SUPPORT *** AFE06051 00002  相似文献

The author applies the 1964 model developed by Stanislaw Czamanski, based on theories of urban growth and industrial localization, to the analysis of urban growth in Mexico. "The advantages of this model in its application as a support instrument in the process of urban planning when the information available is incomplete are...discussed...." Census data for 44 cities in Mexico are used. (SUMMARY IN ENG)  相似文献

The author presents the case that the study of migration over the past century has become too diverse. He reviews works by writers from the several disciplines covering the topic, then cites the need to develop a consistent classification of the types of migration and their origins using standardized terminology.

The zoning process is a distributive process in which benefits are conferred on some and denied to others. Because zoning decisions are not neutral in their consequences, politicians must take responsibility for the patterns of benefits and costs which result from particular zoning policies. Technical expertise and planning principles cannot be regarded as sufficient grounds on which to base inherently distributive policies. This paper analyses the distributional consequences of two rezoning cases in Toronto to illustrate the trade-offs between neighbourhood preservation and housing opportunity.This is a revised version of a paper presented at the Annual Meeting of the Canadian Political Science Association, London, Ontario, May 1978.  相似文献

Recent literature reflects the increased use of RIA as a qualitative and quantitative tool. This study exemplifies the problems that may arise when this technique is used for quantitation. Caution must be exercised, and a physiological and toxicological understanding of each particular drug is essential to provide credible results. It is evident that the sensitivity and ease of the RIA method for methaqualone makes it invaluable as a screening test, but confirmation and quantitation of this drug must remain with those methods that can quantitate each metabolite.  相似文献
