This Article examines the issues and questions which underlie the debate over the admission of "medical treatises" into evidence. The admissibility of this type of evidence is at issue most often in litigation involving complex medico-legal issues. This article outlines the evidentiary basis for admission of medical treatises and discusses the quality of medical treatises in an effort to determine what value to the fact-finder these treatises actually hold. The authors contend that there is an inherent untrustworthiness associated with medical treatises, but do not go so far as to suggest that medical treatises should never be admitted. The Article concludes that there is a need for greater caution in determining admissibility and recommends safeguards to better guarantee trustworthiness and reliability. 相似文献

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 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.
