Should counseling psychology remain a distinct specialty or should it merge with clinical psychology? Recently, a growing amount of attention has been directed toward the increasing similarities between the counseling and clinical specialties, and musings about integrating them into a generic training model have emerged. This position paper considers some problems with the current divisions existing between counseling and clinical psychology. Three basic points are examined: (a) the effects of language systems on the counseling and clinical specialties; (b) the normal-abnormal dimension of behavior as a weak justification for distinct specialties; and (c) the fostering of distorted views of human behavior through counseling and clinical training programs.  相似文献

Although cerebral anoxia is not thought to be responsible for triggering near-death experiences (NDEs), the issue is not so clear in the case of hypercapnia. Detection of normal blood gases in Michael Sabom's (1982) case study seems to be the major reply to suggestions that hypercapnia may have a causal role in NDEs. We argue, however, that routine arterial measures of blood gases are not a reliable indicator of cerebral levels.  相似文献

In this article the perspective shifts to the “upstream” end of the agricultural knowledge and information system (AKIS). Because knowledge policy and strategic decision-making are not the prerogative of the public sector, organizations such as cooperative unions and multinational companies are included. After considering the influence of the changing environment on the nature of the AKIS, the role of knowledge management and policy in the emerging knowledge and information market is examined. Special attention is given to public and private R&D. The article then looks where information technology (IT) fits in and what considerations determine strategic investment in IT projects and sustained services. Some of the European experiences with this strategic investment are evaluated.  相似文献

Despite demonstrations of the utility and cost effectiveness of behavioral programming, such techniques are not commonly employed in psychiatric inpatient settings. Several explanations for this have been proposed, including inadequate levels of training and competence in behavioral programming among prevalent treatment staff. This study employed a multiple choice inventory to assess behavioral knowledge among subjects representing several direct care disciplines commonly found in inpatient psychiatric settings. The results support assertions of relatively low levels of behavioral knowledge among disciplines that are most prevalent in such settings. The implications of these results for initiatives to enhance behavioral knowledge and skills are discussed.  相似文献
