Since the initial studies of derecognition, many articles have focused on the issue, by and large pointing to a slow increase in derecognition. However, a small number have indicated it is actually much larger. This paper shows that derecognition is even greater than these suggest and that its nature has changed. The paper looks at the contexts of this rise but argues that derecognition should not yet be seen as a major problem facing the unions. 相似文献

Summary Standard laboratory posted-offer markets respond slowly and incompletely to demand shocks. In these one-sided markets, where sellers control the setting of prices, very little information is transmitted via the process of exchange. For this reason, traders have trouble distinguishing randomness in their own experience from changes in market fundamentals. This paper reports the results of twelve laboratory markets conducted to assess whether some common variants to standard posted-offer rules can correct the adjustment deficiences. Although discounting, multiple postings and excess demand information all improve performance, we find that response remains poor, and efficiencies low.Support for this research was provided by the National Science Foundation (SBR 9319842 and SBR 9320044), and the University of Virginia Bankard Fund.

The simulation problem is one of the most commonly used formats in computer-assisted instruction (CAI). In medical education, a patient simulation problem is known as a patient management problem (PMP). A number of computerized PMP systems are currently available. However, to date, there is no record of PMP systems having been developed using artificial intelligence. This is noteworthy since artificial intelligence techniques could help in the generation of more effective and intelligent instructional systems.
This paper analyzes and evaluates existing instructional simulation software in clinical medicine in terms of effective educational design attributes. Components of effective PMP systems thus identified are incorporated into a computerized instructional system which uses artificial intelligence techniques for teaching problem-solving and diagnostic skills to undergraduate medical students. 相似文献

社会主义经济是信用经济,没有信用,就没有秩序,市场经济就不能健康的发展。加强企业信用管理的风险控制是现代企业的一项重要任务。进入WTO标志着中国经济更加开放,国际贸易更加纷繁复杂,在机遇透人的同时,企业也潜伏着越来越大的风险,尤其是企业信用风险。因此强化企业的信用风险管理,建立与完善企业内部信用风险管理体制,仍然是企业面临的一项重要课题,笔者从多方面阐述了企业信用风险形成的原因以及如何建立风险管理机制等问题。 相似文献

财政分权与义务教育财政管理体制问题探析 总被引:2,自引:0,他引:2
我国是成功实施财政分权化的国家之一。作为公共财政框架部分之一的义务教育也实行了分权化管理,义务教育办学的责任主要地落在了县、乡两级地方政府身上。而我国庞大的义务教育事业由县、乡甚至村脆弱的财力来承担,可谓“杯水车薪”:一些农村地区和贫困山区学龄儿童无学可上,无书可读等现象屡见不鲜。可见过度分权化的义务教育财政管理体制是制约当今中国义务教育发展的症结所在。 相似文献

This article examines the external shocks and subsequent adjustment processes in the Soviet Union, China, and Hungary during 1974–76, 1979–81, and 1984–87. It compares the experiences of the three socialist countries with regard to external shocks to those of inward-and outward-oriented groups of newly industrializing countries (NICs). In contrast to the NICs, terms of trade effects were of secondary magnitude to export demand effects of external shocks in the three socialist countries during the first two periods. The oil-exporting Soviet Union had beneficial terms of trade effects during the first two periods, with unfavorable effects coming only in the third period. The adjustment responses to the external shocks varied greatly in the Soviet Union from the other two reform-oriented socialist countries and from both groups of NICs. It is interesting to note that the types of responses in the Soviet Union were quite opposite to that one observes for market economies. However, reform-oriented China and Hungary seemed to have response patterns similar to those of market economies, though China's response was similar to the outward-oriented NICs, while Hungary's was similar to the inward-oriented NICs.The authors would like to thank two anonymous referees, as well as Robert Dernberger, Albert Fishlow, Gregory Grossman, Chung Lee, Michael Plummer, Laura Tyson, and Benjamin Ward, for useful comments on this paper. Research in preparing this study was partly supported by a grant from the Institute of International Studies and Center for Slavic and East European Studies of the University of California, Berkeley. 相似文献
