学术社交网络是重要的科学信息资源平台,但少有研究关注高校图书馆对其揭示和利用问题。对我国137所"双一流"高校图书馆对ResearchGate、Acadmia.edu、Mendeley和科研之友4个典型学术社交网络的揭示和利用现状的调查显示,仅有8所图书馆对单一学术社交网络进行了揭示,显示出学术社交网络并未引起广泛重视。提出我国高校图书馆应深刻理解大数据时代学术社交网络的重要性、与科研管理部门加强合作制定学术社交网络发展政策、将学术社交网络与现有资源予以整合、以及深入利用学术社交网络进行科研服务等建议。  相似文献

文章在汇总国外主要专业性科研社交网络站点应用情况的基础上,选择开放型科研社交网络"Academia.edu"作为主要案例。调查分析发现,开放型科研社交网络实际应用中存在信息更新时滞、用户角色以学生群体为主、用户同质化趋势、用户活跃等级排名与科研人员知识水平非对称性等缺陷。科研或学术单位在科研社交网络未来设计中应该合理规避这些缺陷,以便更好地服务于科学交流。  相似文献

ResearchGate为代表的学术社交网络逐渐引起图情学科用户的重视,针对其高影响力科研成果主题内容的揭示,将丰富用户对不同媒介下学科的发展动向与研究重点的认知,亦有助于合理利用学术社交网络来提升个人影响力。文章选取学术社交网络中图情学科高影响力科研成果为研究对象,构建LDA模型挖掘摘要内容,引入来源年份信息分析各时期主题演化情况,在跨媒介比较中揭示网络交流背景下其呈现的内容特征。研究提炼健康信息学、用户信息行为、算法技术、应用开发、通信网络5个主题。从主题强度变化来看,健康信息学表现平稳,用户信息行为、通信网络呈现上升趋势,算法技术、应用开发整体出现下降。与期刊等传统媒介得到的结论相比,学术社交网络中的研究主题与其虽具有一定相似性,但更凸显出学科交叉融合特征。  相似文献

科研社交网络作为新型的科研交流平台,满足了科研人员学术信息和交流群体扩展的需求。通过问卷的方式调查不同机构的科研社交网络用户的使用习惯,分析年龄、职称和研究领域对用户使用科研社交网络的行为倾向的影响,结果显示:20-30岁之间的专业用户最热衷于加入群组,职称对于信息检索行为有着明显影响,研究领域对于系统功能的使用习惯有影响。尽管如此,不同用户还是有些共同特征,比如无论从年龄还是研究领域看,用户在使用科研社交网络时,与陌生人交流行为并不突出,交流更倾向于在熟人之间进行。而且专业用户有别于一般网络用户对互动行为的兴趣,而更青睐系统推荐的内容。表4。参考文献16。  相似文献

This article surveys a sample of sources of the information about Romania available to British readers in nineteenth century British newspapers and periodicals. It traces first contacts between the Romanian lands and Britain after the union of the principalities of Wallachia and Moldavia in 1859, then after their independence from the Ottoman Empire. The article highlights an increased Romanian interest in British periodicals, which reported and reviewed Romanian literature and scholarship. The article concludes that nineteenth century British newspapers and periodicals offer a great variety and wealth of new material previously unavailable or unknown to researchers. It also states that only a portion of a large quantity of this material has been indexed and is therefore available via the bibliographic sources mentioned in the article. The author argues for the need of a new and updated British-Romanian bibliography, which can draw on new online resources offering access to thousands of new newspapers and periodical records.  相似文献

ABSTRACT

The paper looks at library approval plans for material published in Slavic, East European, and Eurasian countries from the selector's point of view. Reasons why a selector would or would not want one are examined. Success with approval plans requires monitoring receipts, as well as good and ongoing communication among the selector, the acquistions department, and the vendor. A preliminary list of vendors offering approval plans for the countries of the region appears in the appendix.  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

Chromebooks and the G Suite group of products, like Google Search, Gmail, and Google Docs, have rapidly expanded in American schools during the past 5 years. The impact of one-to-one Chromebook devices and the pervasive use of Google's software products in American education cannot be overstated. This article explores some of the influences of these products on research, based on the experiences of a librarian and technology coordinator at an elementary education level. The author has several suggestions for effective research with these products in mind.  相似文献

Library historians can learn a great deal from studying the gender of authorship and institutional affiliation of a scholarly journal. The focus of this study is to examine these two aspects of journal production in library history to see who is producing published research in this field. Twenty-three years of Libraries & Culture were chosen as the target volumes. The study reveals that more men than women published in library history as well as locating which institutions were represented. This type of information is usedful to the library historian engaged in the analysis of published scholarship, and more generally to scholars with an interest in patterns of literature production in fields closely related to the social and behavioral sciences.  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

Summary

Although the Internet provides access to a wealth of information, there is little, if any, control over the quality of that information. Side-by-side with reliable information, one finds disinformation, misinformation, and hoaxes. The authors of this paper discuss numerous examples of fabricated historical information on the Internet (ranging from denials of the Holocaust to personal vendettas), offer suggestions on how to evaluate websites, and argue that these fabrications can be incorporated into bibliographic instruction classes.  相似文献
