Scientific publishing in mathematics and physics (as in other exact sciences) is rapidly changing, and it is important to identify and predict relevant changes and their potential consequences. To understand such changes, the authors begin with a brief history of scientific publishing and the rise of digital publishing. The study presents a qualitative comparison of the basic features of traditional and digital forms of publications (books, journals, libraries and databases, archives, webinars, forums, digital learning materials), on the basis of which relevant changes (specific for mathematics and physics) are identified and predicted. Several tables describing the most popular and useful scientific online tools for scientists, professors, students, and engineers are listed. 相似文献

Measuring the output of men and women in science and technology has previously been mostly restricted to case studies or small-scale surveys. Based on an analysis of patent and publication databases, this paper applies a methodology to systematically assign the gender to the names of inventors and authors. The method is applied to 14 countries. The results of this investigation reveal substantial differences across countries in terms of women's relative contribution1 to science and technology, with the central European countries of Germany, Austria and Switzerland all ranking comparatively low in this respect. We also examine trends over time, showing that the data on women's share of publications - unlike the results for patents - hardly increase over time for the already better-performing nations. 相似文献

This article provides an overview of selected Web-based resources containing grey literature in the area of communication disorders. It is geared to practitioners, researchers, students, and consumers seeking reliable, freely available scientific information. Grey (or gray) literature has been defined as "that which is produced on all levels of government, academics, business, and industry in print and electronic formats, but which is not controlled by commercial publishers."1 This paper reviews various general reference sources potentially containing grey literature on communication disorders. This review includes identification of the methods specialists in this field use to obtain this valuable, yet often overlooked, literature. Access points and search tools for identifying grey literature on communication disorders are recommended. Commercial databases containing grey literature are not included. Conclusions presented in this article are considered complementary to traditionally published information resources on communication disorders, such as scholarly journals, online databases, etc. 相似文献

We present a novel approach to re-ranking a document list that was retrieved in response to a query so as to improve precision
at the very top ranks. The approach is based on utilizing a second list that was retrieved in response to the query by using,
for example, a different retrieval method and/or query representation. In contrast to commonly-used methods for fusion of retrieved lists that rely solely on retrieval scores (ranks) of documents, our approach also exploits inter-document-similarities between the lists—a potentially rich source of additional information. Empirical evaluation shows that our methods are effective
in re-ranking TREC runs; the resultant performance also favorably compares with that of a highly effective fusion method.
Furthermore, we show that our methods can potentially help to tackle a long-standing challenge, namely, integration of document-based
and cluster-based retrieved results. 相似文献

Odd people have always been identified and often treated differently in human societies. In modern times, they have been described as being afflicted with a psychological condition to be treated by specialists and assigned to a “crazy” category by general society. Movies about such odd people have a long history. A recent movie, Silver Linings Playbook, presents a picture of mental patients displaying symptoms, but accepted into their home community. A pair of them shows the beginnings of a subcultural community among “odd people,” a version that has not been seen before. 相似文献

This research examines how faculty in academic nutrition, food science, and dietetics locate and access relevant information sources; what information service needs they perceive; which scholarly journals they consult regularly for current awareness; and which journals they use for research and teaching. An e-mail survey was conducted at a large urban public university offering graduate and undergraduate programs in the fields of nutrition, food science, and dietetics. Scholarly journals remain the most common and effective information source for academic nutrition and food science faculty. The PubMed database from the U.S. National Library of Medicine was identified as the main platform for accessing MEDLINE, the most frequently used database for scientific literature searching. The findings inform and support subject librarians in their collection-building decisions, enabling them to improve the services they currently offer to academic communities in these fields. 相似文献
