Librarians and faculty members are now working together through Open Access (OA) publishing to make faculty-produced scholarly content available to researchers worldwide. The University of South Florida Tampa Library has been working with the Berkeley Electronic Press (bepress) Digital Commons platform to create a substantial institutional repository (IR) that includes OA journals, conference proceedings, and data sets, among other materials. Library staff members are currently involved in a variety of activities, including negotiating memoranda of understanding, loading backfiles, registering Digital Object Identifiers (DOIs) with CrossRef, designing layout, doing final publication steps, and assisting with technical issues. In 2011, the IR, Scholar Commons @ USF, went live, allowing the library to pull fragmented collections previously hosted on other platforms into a single system with improved discoverability. This article discusses how the repository was established, what is involved, lessons learned, and plans for future directions. 相似文献

Hybrid Journals: Ensuring Systematic and Standard Discoverability of the Latest Open Access Articles
An important current challenge for research information providers is ensuring the automated discovery of Open Access (OA) content in hybrid journals. We found no evidence of discovery services that are able to systematically identify the crucially important free full-text availability of OA articles regardless of where and how such articles have been published (i.e., in fully OA journals or in hybrid journals). A solution is important because hybrid journals are proliferating and consequently the chances of missing OA articles is real and is happening. Nearly all of the major publishers now provide such journals in order to take advantage of recent changes in research funder requirements, and to be competitive in the new OA business model. By working with a group of scholarly publisher partners and by using standard metadata elements that publishers are already familiar with, we show a systematic and standardized manner to identify OA at the article level. Our proposal is to embed OA-related elements in the metadata freely exposed by publishers for aggregators and discovery services. For example, in the Table of Content (TOC) Really Simple Syndication feeds the publishers use to announce new journal issues and content. Based on the initial results obtained, we discuss the capabilities of our solution, and evaluate the impact produced by our application in the systematic discoverability of OA content from the participating hybrid journals, using an implementation done with the freely available journal current awareness service—JournalTOCs. 相似文献

Four standards and best practices recently released or currently underway at the National Information Standards Organization were presented: Knowledge Bases and Related Tools, Presentation and Identification of E-Journals, Open Discovery Initiative, and Open Access Metadata Indicators. Basics outlining the creation work and deliverables were shared for each project. Applicability of these standards and best practices for different stakeholders of the information community were discussed. 相似文献

The academic library, given its often privileged position on campus, is the information source that can include directional as well as general campus facts among the myriad of print and e-resources for reference. Also, an academic library's audiences can be quite varied and include prospective students or parents seeking more general knowledge of the building and the campus. Many times this need for information drives patrons to the library service desks. Sometimes, especially during the high-demand seasons of new student orientation and beginning of the fall semesters, the desk is so busy that many patrons will leave because they don't have the time to wait. To address this immediate need for information, Texas Tech University Libraries developed an interactive kiosk to provide general information for frequently asked questions in a more efficient, creative, and interactive way. The kiosk provides a fun method of satisfying a patron's information needs without the requirement of a staff member or the need to wait in line for help. The kiosk is available as long as the Library is open and provides a variety of useful answers to general questions, as well as facts about the Library. 相似文献

Although there is a healthy amount in the literature about the importance of motivating student library employees in an academic setting, very little of it discusses the practical aspects of how to motivate students. A supervisor must often use ideas from other disciplines, including the business world and academia. In this article, the author suggests six highly effective, yet cost-conscious methods that have been used successfully in an academic library setting to keep student employees motivated and to retain them year after year. These six methods are: (a) encouraging autonomy, (b) holding contests, (c) providing food, (d) being open to suggestions, (e) using employee strengths, and (f) celebrating seasonal or university-specific events. 相似文献

流动人口子女入园难问题较为突出。本研究从家庭社会经济背景及迁移状况的视角探讨适龄流动儿童接受学前教育的选择问题。使用CFPS(2010)数据,本研究用Logit模型,估计了不同特征的流动儿童家庭为其子女选择接受学前教育的发生概率。研究发现,农业户籍、跨省迁移的家庭随迁子女入园机会更低;有教育储蓄的家庭,其随迁子女入园机会更高;而父母高学历、与子女同住等因素也会在一定程度上提高流动儿童的入园机会。户籍仍是制约流动儿童入园的关键因素。我们据此明示了相应的政策启示。 相似文献

This paper examines the difficulties encountered by Biowatch, a South African civil society environmental organization, in its attempts to obtain access to government information in respect of genetically engineered plants. After establishing the context of South Africa's access to information regime, including a brief discussion of several of its weaknesses, the paper engages in an extended account of the Biowatch case as an exemplar of some of the more pronounced challenges to the effective implementation of the country's access to information legislation. The elaboration of the case is based on interviews conducted with the Director of Biowatch and counsel from the Legal Resources Centre that aided Biowatch, as well as various internal and court documents provided by Biowatch and its lawyers. 相似文献
