Three hundred and seventy-nine participants were tested in the West Indies and in Canada, with the Rotter Locus of Control Scale and the Wolfgang Interpersonal Distance Test. The results indicated that West Indian adolescent students were more internally controlled than their Canadian counterparts. Also, overall, West Indian students showed more approach behavior toward significant interpersonal figures than Canadian students. In addition, no correlation was apparent between locus of control and social distance, suggesting that they are separate constructs. Implications of the findings for social adjustment of West Indian immigrants in Canada are discussed.  相似文献

Access to knowledge is increasingly the driver underpinning the globalization of research. In emerging industries, such access is often managed through alliance structures between small entrepreneurial organizations. The literature on international alliances, however, is dominated by studies of “Triad” nation partners (United States, Europe and Japan) which are often larger firms, collaborating for market access motives and usually with established technologies. In addition, prior research has concentrated on particular aspects, such as motives for, and initial circumstances of, alliance formation. Analyses of the dynamic aspects in the relationship between alliance partners are more scarce. This article describes a study of an international research alliance in which the technology is in the superconductivity industry (which itself is not conforming to traditional notions of an emergent technology), one partner is from a non-Triad nation and the primary motive for formation was access to knowledge. We argue that this study has revealed gaps in current alliance research and hypothesize how some more socially based and process-related considerations could enhance the debate on knowledge-seeking alliances.  相似文献

Aaron Wildavsky, a founder and president of the California Association of Scholars, died on September 4, at the much too early age of 63. Professor Wildavsky's life exemplified a total commitment to the university, and his achievements were prodigious. He authored or edited, alone or with colleagues, some three dozen books, and he wrote hundreds of articles. In the thirty years he spent at Berkeley, he was at various times chairman of the Department of Political Science and founding Dean of the Graduate School of Public Policy. He also found time to serve as president of the American Political Science Association and the Policy Studies Association, and to be active in myriad other organizations. When Yale, where he had earned his doctorate in 1959, earlier this year made him an honorary Doctor of Social Science, it stated, “You have improved every institution with which you have been associated.” Aaron Wildavsky was profoundly concerned about the future of the university, the institution that he loved so much and served so well. At the Fourth National Conference of the NAS, held in San Francisco this past April, he expressed his fears about the effect of politically correct faculty hiring practices on the long-range future of education. Academic Questions here reproduces his remarks in the hope—one that, in fact, he shared—that for once his predictions will be proved wrong.  相似文献

A recent “third wave” of neural network (NN) approaches now delivers state-of-the-art performance in many machine learning tasks, spanning speech recognition, computer vision, and natural language processing. Because these modern NNs often comprise multiple interconnected layers, work in this area is often referred to as deep learning. Recent years have witnessed an explosive growth of research into NN-based approaches to information retrieval (IR). A significant body of work has now been created. In this paper, we survey the current landscape of Neural IR research, paying special attention to the use of learned distributed representations of textual units. We highlight the successes of neural IR thus far, catalog obstacles to its wider adoption, and suggest potentially promising directions for future research.  相似文献

In this article, we address the issue of integration of computer environments in the mathematics secondary curriculum, by referring to the results of a research project carried out with the software DERIVE. Firstly, we present the research project and its theoretical framework, secondly, we evidence some didactical phenomenas linked to the DERIVE transposition of mathematical knowledge and learning processes in this environment which, in our opinion, play a crucial role in integration issues.This revised version was published online in September 2005 with corrections to the Cover Date.  相似文献

Recent articles, including those by Dixon and Torres and Hager, criticize tournament playoffs, primarily for reasons of fairness and integrity. Many suggest that playoff and tournament prominence reflect monetary and entertainment interests rather than the pursuit of athletic excellence. Nevertheless, tournament playoffs are increasingly popular. While the concerns are serious, in this paper I defend the overlooked value of playoffs and tournaments. Playoff critics employ too narrow a conception of the best team and too limited a view of excellence. Rather, playoffs and seasons highlight distinct and valuable conceptions of athletic excellence. To better capture this, I consider two alternative championship formats: the hybrid system and championship pluralism. The hybrid system includes a playoff informed by the regular season. Despite its apparent advantages, I reject the hybrid approach. Instead, I propose championship pluralism as a preferred championship model.  相似文献

Statistical analysis and comparison of library print and online holdings are used to reduce shelf area and inform index back-file purchases. Nikki DeMoville of California Polytechnic State University’s Robert E. Kennedy Library combined Counting Online Usage of Networked Electronic Resources (COUNTER) JR2 Access Denied usage reports, holdings information, and print circulation data to identify journals exhibiting a high desirability for online access and low print circulation. In this presentation, DeMoville shared how further combination of this data with ScienceDirect quote lists for back-file journal packages and Web of Science metrics could be used to support the efficient de-selection of print journals, allowing the library to recover the maximum amount of physical space while also acquiring backfile access to those titles most frequently needed in electronic format. The presentation detailed the workflows and comparative methodology used to reach collection management and development decisions for journal coverage, with an emphasis on before and after metrics.  相似文献
