在分析网格存储架构基础上,构建数字图书馆网格存储体系模型,并且阐述了模型中的存储描述、存储组织、存储监控与发现、存储调度这4个过程。存储描述是基于元数据模型来实现的,有用户元数据、存储节点元数据和应用元数据;采用LDAP目录服务器和全局命名服务器进行元数据的存储组织管理;存储监控与发现就是监控整个数字图书馆网格存储状态;根据当前网格存储系统负载状况,由存储调度对系统内的任务进行动态调度。该模型初步实现了存储资源和存储服务高层次的共享。  相似文献

ABSTRACT

The article examines the most important periodicals of ethnic minorities in Poland. After 1989, many ethnic groups (e.g., Germans and Romanies) were allowed to publish journals and newspapers for the first time since the end of World War II. The publications examined show the rich cultural life of the various ethnic groups as well as their current status in Poland. In addition to popular titles, some scholarly publications are also discussed.  相似文献

The author answers a reference question on bibliographic sources for the Ukrainian periodical press 1840–1850. Helpful publications include bibliographies, guides, and library catalogs. These potentially make mention of revolutionary developments in Hungary (such as the Twelve Points paragraph of the Demands of the Hungarian Nation in March 1848, the subsequent April Laws, and Hungary's declaration of independence in April 1949), and elsewhere in the Hapsburg Empire.  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
