在去参加第53届威尼斯艺术双年展开幕式之前的几天,我受邀出席了在意大利北部城市Bergamo的当代美术馆GAMeC举行的国际年轻策展人论坛,今年论坛的主题是"国际策展人的终结?"围绕着像威尼斯双年展、卡塞尔文献展等全球达几十个之多的国际性展览的策展策略和模式进行反思和讨论。讨论之中也不免提到了威尼斯双年展这个一直以一个策展人为主导选择艺术家的大  相似文献

Edith Penrose's The Theory of the Growth of the Firm proposed a process theory of growth based on the pursuit of knowledge by the firm and unconstrained by government. In her subsequent studies of foreign direct investment by large firms in developing countries, Penrose considers the firm and government as actors in the same growth process. This paper explores the development of Penrose's expanded process theory of growth from 1955 to 1973 in which she assumes that neither dual actors nor foreign expansion requires a new or special theory. This finding has implications for the resource-based view and the eclectic ownership–location–internationalisation paradigm interpretations of international business.  相似文献

This study demonstrates that the measurement of technological change and economic efficiency are tightly linked. Efficiency measures may depend on carefully controlling for technological change, while tests of technological change may be sensitive to empirical model specifications. Moreover, the study underlines Solow's (1994) and Romer's (1994) admonition that econometricians should pay attention to industry and institutional evidence in building models of technological change. The empirical results presented here suggest that there has been substantial technological change in the U.S. brewing industry from 1950 to 1992. This occurred in the form of a dramatic shift in technology beginning with the introduction of super breweries in about 1972. There has also been a substantial increase in scale economies, which undoubtedly caused many inefficiently small firms to exit the industry during the 1960s and 1970s. Further results suggest that a more complete specification of technological change and the stochastic nature of the frontier production function leads to higher and more tenable estimates of efficiency.  相似文献

Conclusion The purpose of this study is to reduce information costs in the market for graduate education in economics and the market for Ph.D. economists by providing information on research concentration in each of 19 fields for 1980–1986. Some variation in publishing performance across fields is found in highly regarded universities. Unexpected faculty strength is discovered in some middle level departments for particular fields. Among middle- and lower-ranked departments, substantial publishing diversity across fields is evident.  相似文献

This paper reviews the nature of accounting and auditing problems and the need for application of artificial intelligence (AI) technologies to the discipline. The discussion includes current accounting issues for which new AI development should be fruitful, particularly auditing and assurance. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

This article examines the impact of participation in the National School Lunch Program (NSLP) on children's dietary intake at lunchtime and over 24 hours. Using a fixed effects model to control for selection bias, we find that NSLP participation leads to increased 24-hour intake of six vitamins and minerals—calcium, magnesium, phosphorus, zinc, vitamin B12, and riboflavin—as well as dietary fiber. Participation also leads to a trade-off between children's intake of dietary fat and added sugars whereby participants have higher intakes of dietary fat than nonparticipants but lower intakes of added sugars.  相似文献

As patents and other forms of intellectual property become more pervasive in the next generation of biotechnologies, designing policies and practices to ensure sufficient freedom to operate (i.e., the ability to practice or use an innovation) will be crucial for non–profit research agencies, especially those intent on developing technologies destined for commercial release. Are non–profit organisations exempt from intellectual property claims? What constitutes infringement of a patent? How does a non–profit establish its freedom to operate? We address these issues in this paper and evaluate various options for accessing other people’s technologies. Options include cross–licensing agreements, research–only or cost–free licences, market segmentation strategies, mergers or joint ventures, and patent pooling or clearinghouse mechanisms. Responding creatively to the new intellectual property environment will have far reaching consequences for the future of non–profit research.  相似文献
