数字人文作为一个新兴的跨学科研究领域,正受到许多学科的高度关注.本研究旨在探析国际数字人文研究的跨学科知识扩散趋势,以Web of Science核心数据集为数据来源,通过学科聚合性、学科多样性、学科地位三个维度的四个指标——网络中介中心势、网络密度、网络核心度、DIV指标——进行跨学科特征分析,使用国际数字人文研究中被引次数≥1的目标文献及其施引文献进行知识扩散研究,并基于桑基图进行可视化展示.研究表明:国际数字人文研究的跨学科性越来越强,艺术与人文学科、工程学等学科近年在国际数字人文研究中的地位渐趋重要,而图书情报学等初始相关学科的核心度则呈下降趋势.国际数字人文研究网络核心度的下降有利于数字人文与其他学科建立更多的联系,从而更好地吸收其他学科知识、扩大研究范围.在知识扩散过程中,计算机科学、图书情报学两个学科的知识流动较为频繁,语言学领域的论文越来越受到其他学科的广泛关注. 相似文献

研究我国人文社会科学各学科间知识扩散网络和路径,可以为开展跨学科研究和促进学科之间的交叉融合发展提供参考。采用群体中心度指标,基于文献的引证关系和共被引网络对不同学科的网络位置进行了测度,探析了以共被引网络群体中心度为测量指标的我国人文社会科学领域知识交叉与知识扩散状况。结果表明经济学、政治学、法学等学科作为我国人文社会科学领域的重点研究领域,在整个科学知识网络中扮演着重要的角色,其研究内容本身具有较强的学科交叉性,且对各学科都有较强的辐射作用。此外,马克思主义学科对经济学、心理学对教育学和体育学、哲学对政治学、环境科学对人文地理学等也有较强的知识扩散能力。 相似文献

SUMMARY This article discusses Jewish book publishing in most of the Soviet Union's successor states after 1990. All publications on Jewish history, culture, traditions, and religion (Judaism) are included under this rubric. In addition to scholarly and educational publications, fiction translated from Yiddish and Hebrew, and “Russian-Jewish literature” are also included. The author provides statistics and discusses basic themes, linguistic issues, and problems encountered in the post-Soviet states. The article lists different publishers and organizations involved in Jewish book publishing. 相似文献

This article describes a study of the two most popular plagiarism-detection software platforms available on today's market—Turnitin (http://www.turnitin.com/static/index.html) and SafeAssign (http://www.safeassign.com/). After a brief discussion of plagiarism's relevance to librarians, the authors examine plagiarism-detection methodology and conduct a review of the current literature regarding plagiarism-detection efficacy. To evaluate detection efficacy for Turnitin and SafeAssign, the authors constructed a brief study in which twenty sample papers containing portions of plagiarized material were submitted to each platform. The results show that Turnitin had the highest overall success at plagiarism detection with an 82.4 percent detection rate. Additionally, both platforms had a combined false-positive detection rate of 16.8 percent. The authors conclude that close review of material suspected of plagiarism is still essential for proper identification. 相似文献

Abstract The Russian government is exerting increasing control over the country's media, although the media are resisting. This government-media conflict is relevant to Western academics and libraries, because the variety and quality of Russian periodicals is at stake. In addition, if the media are constrained, publishers of books are likely to experience restrictions, too. The difficulties the government is having in controlling the media, however, are a measure of how much Russia has changed. At the same time this conflict is occurring, book publishing is thriving. Official statistics show the number of titles published surpassed even the previous record set in 1977. Planning is in progress to restructure the state book industry sector, including publishing, printing and distribution. Book prices have increased more rapidly than inflation, and postage costs have also increased. Russian Press Service is doing its best to keep its prices to Western libraries down. 相似文献

SUMMARY Describing her experience of establishing an Electronic Document Delivery Service at the library of the Lahore University of Management Sciences (LUMS), the author discusses the various issues, which significantly effect the net cost, delivery time and management process of providing such a service by a library in Pakistan. While presenting multiple options leading to an effective solution, the advantages and disadvantages of each option have been highlighted, and their implications, with particular reference to Pakistani libraries, have been discussed. The various points to be considered by Pakistani Librarians, while selecting a commercial Document Provider, have also been discussed. In the end, the author discusses the potential of using the Electronic Document Delivery facility as a time-saving and cost-effective tool for Resource Sharing among libraries in Pakistan. 相似文献

ABSTRACT No one can predict what document delivery will look like in the future, but librarians must guard patron confidentiality even in an electronic environment. This time it isn't an easily solved problem like finding another way of recording circulation than handwriting patron names onto circulation cards, it is instead the tracking of personal information attached to electronic text supplied by publishers that is a potential violator of patron privacy. Unmonitored in their efforts to protect their intellectual property without considering the rights of their customers, publishers could pose a threat to their customers' privacy, thus limiting their legal right of free access to information. Although encryption technology would appear to provide an answer to the confidentiality problem, it is not a panacea and that must be considered as the National Information Infrastructure is developed. Librarians need to stay alert to the developments in electronic publishing to be sure their concerns for patron privacy continue to be heard. 相似文献

This article uses the metaphor of building to frame discussion about how we prepare for the provision of learning in the years
to come. The intention is to catalyze key conversations that will shape how, where, and why we learn. The principal focus
is on areas such as blended learning, mobility, gaming, social networking, holographics, analytics, and the human touch. However,
the larger theme involves challenging the reader to vision how we bring the best of traditional education forward, combine
it with new technologies and techniques, to reach and teach students well. 相似文献

The Book Industry Study Group and The Idea Logical Company carried out an online survey to capture publishers’ comments on
how market conditions were changing and what they are doing differently as a result of the economic pressures in the consumer
market. About 250 individuals responded to the online survey. Interviews were carried out of more than a dozen executives
at large and small publishers and their accounts to get further insights. The goal was to identify what are the sales conditions
for trade book publishers today and what publishers are doing to change sales and marketing and even editorial practices to
accommodate changing times. What we have learned from that joint effort is reflected in this article. 相似文献
