Recent failures of government information systems to achieve their objectives have highlighted the risk involved in large-scale information technology projects. This article looks at one example, the computerization of the UK social security system, in the light of recent discussions of large-scale technologies and the particular problem of inflexible technologies as defined by Collingridge. It is argued that large-scale government computing projects can fit the criteria of inflexible technologies, although this is not an inherent feature of information technology. There are always more flexible alternatives available: this is illustrated using examples from both private and public organizations. 相似文献

A 22-year-old Korean soldier, who had received blows to the neck and epigastrium from an officer 10 h earlier, suddenly died after massive hematemesis. He had been in relatively good health except for episodes of blood-tinged vomiting approximately 5 and 7 months prior to this event. Postmortem examination revealed angiodysplasia involving the gastroesophageal junction, and the stomach was distended with blood. No abnormal findings were present around the whole viscera, and the duodenum was free of blood. The pathologic significance of upper gastrointestinal angiodysplasia as a potential source of bleeding and a chronologic correlation between the trauma and bleeding are discussed. 相似文献

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

Abstract. This paper provides a defense of the following thesis: When there is reasonable disagreement over the design of morally necessary collective action schemes, it would not be reasonable to reject the authority of a democratic decision procedure to settle these disputes. My first argument is a straightforward application of contractualist reasoning, and mirrors T. M. Scanlon's defense of a principle of fairness for the distribution of benefits produced by a cooperative scheme. My second argument develops and defends the intuition that treating others morally requires respecting their exercise of moral judgment, or a sense of justice. I conclude by addressing the problem of disagreement over the design of the democratic decision procedure itself, and rebutting Jeremy Waldron's claim that democratic authority is incompatible with judicial review. 相似文献

Abstract. For a broad range of policy sectors, liberalization was the predominant goal during the 1990s, and the policy change involved gave rise to a wide range of academic debates. In this article we analyze the consequences of these far-reaching policies for the policy process itself. We ask whether the policy changes significantly altered the characteristics of policy processes by considering the timing and extent of the changes in policy networks during those years. More concretely, we discuss the extent to which policy networks changed as a result of market opening, considering the case of the telecommunications policy network in Spain. Using data from two successive surveys, we compare the network structure before and after market opening. Our findings show that only slight changes occurred during this period, making the network denser but not more open. Thus, we suggest that a more successful liberalization probably would have required a network that was more open to new entrants and in which power was less centralized and so able to guarantee a competitive environment. 相似文献

A dissecting intramural haematoma of the coronary artery is an infrequent cause of sudden and unexpected death. Most cases are women and in a significant number of these women, the haematoma occurred at term to 80 days postpartum. Because the intimal rupture and communication with the lumen were not found in most of the cases, the site of rupture has been considered to be a vasa vasorum. The authors report on a case of one woman who was at a later postpartum period (106 days). The microscopic finding of the dissected coronary artery revealed two intimal tears in a section. The case showed that the dissecting intramural haematoma of the coronary artery is caused not only by the rupture of the vasa vasorum but also by the rupture of the intima. 相似文献
