根据对北部湾经济区30所高校图书馆数据库建设情况的调查,发现该地区高校图书馆数据库的类型比较全面,全文数据库所占比例较高且中文数据库数量多于外文数据库。但同时也存在不少问题：数据库建设不平衡,重复建设严重,建设缺乏统一标准,自建的数据库及特色数据库少。要建设好经济区高校图书馆数据库,应充分发挥区域自治制度和经济区发展规划的政策优势,统一规划,合理布局,加大引进数据库的力度,加强自建特色数据库的建设,创建高校图书馆联盟,最终实现资源共建共享。 相似文献

Evaluators of library programs have different perspectives on why to conduct an evaluation and also how to do so. The author
suggests that a minimal approach to conducting a library program evaluation is to prove that the program exists. But this
perspective has expanded to include different degrees of interest in the client and operations, culminating in a combined
focus that leads evaluators to conduct outcome assessments. The chapter includes speculation on what motivates managers to
undertake an evaluation, a review of some ways that library evaluations are conducted, and a discussion of several examples
of program evaluations. Though there are not single directives for undertaking a library program evaluation, there are a variety
of tools and advice to entice librarians to do more of them as a way to improve understanding the value of a library to its
clientele and in society. 相似文献

Planning a conference at the best of times is intense. Add in a lingering pandemic and the first attempt at a hybrid conference then planning a conference can become extremely stressful. Selecting sessions for a conference can fall under the responsibilities of librarians contributing to the profession and completing service requirements. This paper maps the research, creation, and implementation of a rubric to guide the evaluation of session proposals for a technical services library conference and the creation of a webpage to inform those thinking of submitting a proposal. The deliverables were a page added to the organization website and a rubric. 相似文献

At this critical point in its development as a burgeoning market economy ensconced within a socialist political system, China faces a dilemma in becoming a fully‐fledged player in the copyright arena. Over the past two decades, China has made great strides in creating a legal and governmental framework for the administration and enforcement of copyright. But its implementation has left much to be desired, owing partly to inadequate resources of money and personnel, partly to insufficiently harsh penalties for infringement, partly to cumbersome procedures required to bring action against infringers, and partly to a general cultural tolerance for practices that run contrary to cultivating a broad‐based respect for copyright. This article proposes that a balance of pressure and encouragement is likely to have the best chances of success in overcoming these problems and ensuring that China will become fully welcomed into the international publishing community. 相似文献

Engagement on social networks is a complex concept, in which many interconnected, difficult-to-assess components interact. It is precisely this complexity which motivated this work, which proposes a composite index as a tool to measure engagement. Using TOPSIS, a multicriteria method that bases its ranking on minimizing the distance to the ideal point and maximizing the distance to the anti-ideal, a mix of indicators based on two approaches is used: the tweet approach and the follower approach. The former reflects engagement based on user production, and the latter measures engagement by popularity. This index was applied to a group of Social Media Influencers and a general ranking was obtained, as well as a ranking by each approach to measuring engagement. A comparison of the rankings generated by the different approaches shows the suitability and pertinence of both, as it is confirmed that they measure different aspects, and that both are needed to offer a holistic view of the engagement generated by a user on Twitter; this is a new finding compared to prior studies, which only focused on one approach or the other. 相似文献

Since 1962 the members of the loosely organized Detroit Medical Library Group have carried on a slow but steady self-examination program. They found a need to increase resources and developed a periodical exchange, then a need to identify these resources and did so by means of a serials list. More recently, a similar program for texts and monograph resources was begun. Data, more particularly that of the interlibrary loan process, is being gathered to show the flow within the area and the flow from outside to further identify the existing resources. They have made contact with the administrators of the biomedical institutions and gained their backing (a) to further study the makeup of the community and (b) to formulate an administrative structure through which these institutions can act. These activities are evidence of the beginning of a strong medical library network for the Metropolitan Detroit Area. 相似文献

Washington State University received a National Endowment for the Humanities grant to offer a pilot two-semester World Civilization course as part of the general education core curriculum. Two reference librarians were selected as members of the interdisciplinary faculty group to design the course, to relate it to the required Freshman Composition (English 101) course and to ensure the integration of basic library use skills. The two librarians were asked to develop library/classroom integrated assignments to meet course objectives and to serve as models for those teaching the course. The focus of the assignment is on selection and evaluation of information sources that approach a topic from a particular viewpoint (i.e., liberal, conservative, or middle-of-the-road), provide a popular or a scholarly treatment of the topic, and reflect a targeted audience approach (e.g., layperson or professional). 相似文献

This phenomenological study examines the unique perceptions of immigrant women concerning the public library as a meeting place, a support to integration into American culture, and a provider of programs for acquisition of the English language. The library offers a place for observing the culture of the new country from a distance to active participation; it is an arena for comfort and consolation in a difficult life situation as well as an arena for activity and participation. It provides support in developing friendships, acclimating to a new culture, learning a new language, and providing avenues to employment. Three mothers, who fulfilled the criteria for the study, were selected from an initial focus group. Women from Kurdistan, Mexico, and Indonesia were interviewed individually to gain an understanding on the issues brought forth in the focus group. They participated in interviews over the course of 6 months. These programs became a fortuitous blending of an established community with a group of families looking for a support community in a new country. This study has implications for institutions serving immigrants as they look to find a community of support, to learn English, and to acclimate to American culture as they create a comfortable identity that blends their home country with the new country. 相似文献

Editor’s Note: A JRAM email symposium is structured in the same way of a convention symposium. A group is empaneled to discuss an issue, a moderator asks the panel to address a series of questions while one or more discussants are tasked with responding to the panelists and acting as a surrogate for the audience in the understanding and the interrogation of the ideas presented. In this symposium, panelists were emailed a list of identical questions by the moderator. Panelists and discussants were selected for their knowledge, experience, and the diversity of ideas they bring to the symposium. The answers were then collated, lightly edited for spelling or syntax, arranged in a readable order, and then emailed to the discussants for their feedback. Follow-up questions were only asked for the purpose of clarity with regard to a definition or a convoluted sentence. Both panelists and discussants were encouraged to respond conversationally to the issues. 相似文献
