一种学术排序新指数——f指数探析 总被引：6，自引：0，他引：6
在h指数启发下发现一个新的学术排序指数--f指数,该指数与学科相关,综合了数量与质量因素,普适于学科、国家、机构、期刊、学者多层面学术排序,其计算公式为:f=(100×HCP)/(P)×(100×C)/(TFC)=CPP×(HCP)/(TFC)×104≥0其中P,C,HCP分别为论文、引文和高引论文数,TFC是相关学科的总引文数,CPP=C/P是平均引文.22个学科、 18个国家、 18所大学、 10种期刊和10名学者的f指数被具体测算.实算数据表明f指数值处于 0～100之间,f≥1表征优秀. 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
