While the beneficial aspects of a public accounting office's activity are not disputed here, it is argued in this article that four major distortions are produced: the concern with administrative rationality overlooks costs elsewhere (Section 2); budgetary aspects are overvalued compared to other issues (Section 3); incentives-oriented behavior is suppressed (Section 4); and the evaluation is biased by concentrating on minor, instead of major, aspects of inefficiency (Section 5). Section 6 considers alternatives to public accounting offices and makes some suggestions for new institutional arrangements particularly for constitutional rules.  相似文献

The primary aim of this paper is to review the literature on preadolescent friendships in order to examine the relationship between preadolescent friendships and social support in adulthood. Social supports are important to health, both directly and as a stress buffer. Few studies, however, have specifically examined adult social supports from the perspective of their developmental precursors and critical developmental periods. Some data indicate that the preadolescent period may be of particular importance to the development of adult social skills and ties. Observational and empirical studies of preadolescent peer relationships, and in particular best friendships, suggest unique and critical contributions to adult social relatedness. Present research is suggestive but is insufficient to validate preadolescence as a critical period in adult social relatedness. Our review has implications for better understanding the mechanisms by which preadolescent friendships effect adult social support—an important mediator of the effects of stress on health. Further longitudinal study is needed.Received Ph.D. from University of Maryland.

Presented in this paper are the initial results involving the use of the nose or outer ear as temperature measurement sites to determine the postmortem period of the human corpse. Simple mathematical models for both sites are developed based on cooling curves of five corpses. Analysis of errors between actual and calculated postmortem intervals suggest that in its present form, the described methods would not be suitable for use in accurately determining the time since death of human corpses.  相似文献
