[目的/意义]考察国际图联图书馆电子借阅原则及相关文献,解析国际图联关于图书馆电子借阅和电子图书知识产权的新观点。[方法/过程]图书馆电子借阅面临着出版商知识产权保护的限制,国际图联以《图书馆员及其他信息工作者的伦理准则》等文件表达过其立场。现在国际图联通过"电子借阅"和"电子阅读权利"表达了新的立场,并发布了《国际图联图书馆电子借阅原则》。[结果/结论]分析该原则的具体内容,认为应该以公众权利作为图书馆电子借阅的思想基础;国际图联提出的以电子阅读权利为理念的电子借阅原则,很好地表达了图书馆界对电子借阅服务的诉求。 相似文献

[目的/意义] 以社交媒体用户为研究对象,调查他们对于自身的社交媒体数据被采集用于研究的接受意向,并探索熟悉度、信任、利他主义对接受意向的影响,剖析知情同意程序的必要性,同时提醒学者进行伦理反思,为建立社交媒体数据研究伦理规范和与用户开展伦理风险沟通提供参考。[方法/过程] 建立用户从知情到同意的心理机制模型,采用问卷调查法收集来自新浪微博用户的数据,共获得320份有效问卷,并对模型进行验证。[结果/结论] 验证出两条有效的心理路径：熟悉-利他主义-接受意向和熟悉-信任-利他主义-接受意向。发现熟悉度和利他主义是影响用户接受意向的重要因素。在社交媒体数据研究中,用户有较强的伦理需求,知情同意程序很有必要。研究者还可以主动表达尊重及认可,以提升用户的利他主义,提升用户的接受意向,规避研究过程中的伦理争议。 相似文献

[目的/意义]时间是信息行为中普遍存在的情境因素,然而将时间视为稀缺资源,探讨其对信息行为影响的研究较为零散。本研究梳理信息行为领域中对时间限制和时间压力影响的相关研究,总结时间限制与时间压力对信息行为的作用和影响,以加深对时间因素的理解,呼吁信息行为领域对时间的关注。[方法/过程]在阅读与筛选近10年相关领域研究的基础上,本研究系统性归纳与总结时间限制与时间压力对信息行为的影响,着重梳理时间限制与时间压力在不同类型的信息行为过程中的角色。[结果/结论]研究发现,时间限制与时间压力会对任务完成过程中的信息行为(包括搜索、浏览与撰写行为)、无明确任务下的信息偶遇行为和信息决策行为均产生影响。未来研究者应厘清时间限制、时间压力及其相关概念边界,明确时间压力测量标准,同时关注时间压力积极作用。 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

ABSTRACT The history of the almanac in Croatia is reconstructed through primary research in bibliographic and archival sources. The almanac is a vehicle for knowledge communication in informal contexts, engaging both oral tradition and literary forms traceable to medieval literacy and ways of structuring knowledge. The history of the almanac in Croatia reflects the changing context of the book trade, literacy, and the evolution of language. Four main stages are identified: (1) the beginning of the annual almanac in the seventeenth century; astrological almanacs reflecting the sensibility of the Baroque period; (2) the Enlightenment's stimulation of almanac publishing in the spirit of contemporary secular reforms in agriculture and education; (3) nineteenth-and twentieth-century almanac trade, showing complex and overlapping networks for the production, distribution and appropriation of printed almanacs;(4) roughly the end of World War II, when the almanac slowly moved out of the role of a popular mass medium and into specialized niches represented by regional, diaspora, and religious almanacs. 相似文献

Some key questions for publishers in today’s market are: Could Amazon’s recent merger and acquisitions strategy create a disruptive or paradigm shifting business model in the publishing industry? Do their recent actions post mergers and acquisitions illustrate a predicable pattern of behaviour that publishers can strategize around? This paper will explore these questions and look at some of the possible reasons behind Amazon’s business practices and the possible consequences to publishers. 相似文献

ABSTRACTGerman authorities are expecting more than 1 million refugees by the end of 2015. These people come to Germany to seek protection and assistance and to build a new life, therefore it is important to welcome them and to assist them in their integration as soon as possible. This situation creates a versatile and perfectly fitting opportunity for cultural and educational programs, including libraries, which can play a vital role in this integration process. The key to integration is the knowledge of the German language, and the most important challenge now is to teach the necessary language skills to as many asylum-seekers as possible. 相似文献

Abstract Many libraries use RSS to syndicate information about their collections to users. A survey of 65 academic libraries revealed their most common use for RSS is to disseminate information about library holdings, such as lists of new acquisitions. Even though typical RSS feeds are ill suited to the task of carrying rich bibliographic metadata, great potential exists for developing applications that can exploit metadata exposed to Web services via RSS. Using the MODS metadata format, entire catalog records can be seamlessly embedded in RSS 2.0 feeds. Existing tools, such as Library of Congress Java toolkits and XSLT stylesheets, can facilitate this process, while a new XSLT stylesheet may be used to create the RSS feeds complete with MODS records. As an example of the added functionality these MODS/RSS feeds can offer, records from a MODS-enriched RSS feed can be ingested into a non-RSS application such as Zotero. As more emerging library technologies use Web services architectures to handle data objects, the ability to syndicate catalog records will become more critical to providing innovative library Web services. 相似文献

SUMMARY The Nevada Constitution provides voters with the ability to propose new statutes, amendments to existing statutes, and amendments to the State constitution through the initiative petition process. Voters can also approve or disapprove of existing statutes through the referendum petition process. Both require the circulation of a petition to collect a minimum number of signatures before the Secretary of State will place the measures on the ballot for the general election. As with other topics of law, Nevada has a profound shortage of research resources on initiatives and referenda, but State law and government Web sites provide enough information to allow for significant research. 相似文献

SUMMARY This article is a case study of Ariel use at the University of Texas at Austin. The author divides the history of Ariel use into three distinct stages: resistance, full implementation, and enhanced. For each stage the advantages and disadvantages of using Ariel are discussed. The author concludes that using Ariel saves both money and staff time and permits faster delivery of documents than other methods. 相似文献

SUMMARY CISTI, the Canada Institute for Scientific and Technical Information, is one of the world's largest document delivery suppliers, and was among the first to be fully automated. The revolutionary Intel-liDoc system, developed during the years 1993 to 1995, provided for end-to-end automation of the document delivery process, which has enabled CISTI to improve its service and accommodate growth. From the beginning Ariel was, and remains, an integral part of IntelliDoc. This article describes how Ariel has been integrated into IntelliDoc and into CIS-TI's services, showing the benefits to CISTI and to its clients. 相似文献
