ABSTRACT

Due to limited disclosure requirements, obtaining private equity (PE) and venture capital (VC) information presents challenges to academic researchers. However, the universe of commercially available resources that focus on private equity and venture capital has increased substantially over the past decade. This article examines recent academic business literature to evaluate whether resources from newer providers in this subject area (CB Insights, PitchBook, Preqin, PrivCo) are gaining traction among academic researchers. It also matches the resources that researchers are citing to library holdings in an effort to measure library support for PE/VC research. The results indicate that data from traditional providers (Dow Jones, S&P Capital IQ, Thomson Reuters) continues to be heavily used and that libraries are providing moderate support for PE/VC research.  相似文献

Skill mix in primary care should be governed by research-based evidence of how skills may best be distributed among health professionals in order to optimize the cost-effectiveness of health service delivery. There is a dearth of research in this area, yet many changes in skill mix within primary care have still to be adequately researched. Existing evidence of the nature and cost-effectiveness of skill mix change is scattered across the specialist literature of many different disciplinary groups, making it difficult to form a coherent overview of service provision. This paper reports on a project that sought to create a comprehensive database bringing together specialist literature relating to skill mix in primary care, as resource for health services researchers, providers and purchasers in the UK.  相似文献

The importance of cataloging research was highlighted by a resolution declaring 2010 as “The Year of Cataloging Research.” This study of the peer-reviewed journal literature from 2010 to 2014 examined the state of cataloging literature since this proclamation. The goals were to determine the percentage of cataloging literature that can be classified as research, what research methods were used, and whether the articles contributed to the library assessment conversation. Nearly a quarter of the cataloging literature qualifies as research; however, a majority of researchers fail to make explicit connections between their work and the missions of their libraries.  相似文献

[目的/意义]分析国内与国际跨学科研究人员文献需求的特点并比较异同,为跨学科研究的文献保障工作提供依据,以促进跨学科研究的国际合作。[方法/过程]使用引文分析法,以1998-2016年发表在CSSCI和Web of Science上南海争端相关文章的期刊与图书类引文为样本,从年代分布、被引频次、学科分布与出版机构等方面,分析国内与国际南海争端研究引文的特点与差异。[结果/结论]国内研究对较新中文期刊和经典外文图书依赖度高,中文图书缺乏国际认同。南海争端研究整体偏向人文社会科学领域,但国际研究较国内研究在引文学科的分布上更加广泛与均衡。权威、主流出版社是国内与国际研究共同的选择,少数研究机构出版社开始进入了跨学科研究者的视野。  相似文献

This study examined the use of academic libraries by academic sponsored researchers in the social sciences at five universities in the greater Boston area. It provides information about researchers use of the library during the proposal development and research stages; it inquires into other information sources employed by the researchers; and it collects data about the types and ages of information materials used in support of the respondent's research projects. Analysis of the responses indicates that for the majority of the researchers, the library was used between one and five times during their proposal development work but that the resources of the library were not a factor in the development of their research proposals. While the researchers indicated that they had used or expected to use their campus libraries as well as other libraries during the course of their research, they also expected to obtain research related information from other sources. They ranked their personal collections first in importance as the place they turned to for information materials in support of their research activity, with their campus library or libraries ranked second.  相似文献

深交所创业板开启以来,越来越多的经济学、管理学、法学等学科的研究者开展创业板领域相关研究,这对目前国内外非常有限的文献资源提出了更高的要求。开放获取是一种全新的学术交流模式,改善了传统期刊论文发表周期长、时效性不强的局面,为创业板研究者提供了免费获取最新研究成果的机会。创业板文献资源开放获取的基本类型有开放获取期刊、开放获取仓储和预印本文献,获取途径主要有国内外综合资源的OA搜索引擎和证券类专业网站两大类。可以从保证文献资源质量、加大宣传力度和建立共建共享系统等方面改善创业板文献资源开放获取的应用。  相似文献

基于文献的评价往往无法针对特定年龄阶段的科研人员进行,因为文献著录项目中没有年龄这一字段。笔者所在课题组利用SCOPUS文摘与引文数据库,以机构为单位计算三个指标:该机构40岁以下科学家发表论文的篇均被引次数,篇均被引次数越多分越高;40岁以下科学家发表论文的被引次数进入本领域前5%的人的数量,人越多分越高;该机构所有这些40岁以下科学家的平均年龄,年龄越低分越高。对上述指标进行归一化,并根据指标权重对研究机构进行排名,评价中国主要科教机构在青年科学家培养方面的表现。  相似文献

[目的/意义]作者主题模型作为近年来计算机领域关注度较高的新型概率模型,在文本挖掘与自然语言处理等方向已有广泛应用。分析国内外作者主题模型及其改进的思路与应用,更好地把握其研究现状,以期为计算机、图书情报等相关领域科研人员提供参考。[方法/过程]本文选取Web of Science核心数据库、DBLP及中国知网(CNKI)数据库作为文献来源,通过制定检索规则、去重及人工判读等操作提炼出关于作者主题模型及其改进方法的文献集,从模型应用过程的视角,结合文献分析法对现有研究进行总结归纳。[结果/结论]通过分析发现,现有相关研究已形成较为完整的分析流程,且模型的改进角度、适用领域也日益多样化。但性能优化、模型评价指标的规范完善以及在图书情报领域的进一步应用等方面仍有待深入探索。  相似文献

我国图情档学科认为博物馆是文化信息数字资源整合的主体之一。博物馆中以其展品为代表的文化信息资源对满足公众多样化的文化需求、增强中华文化竞争力起着重要作用。本文借助Citespace分析软件,通过对作者、机构、关键词可视化图谱的绘制,识别出我国图情档学科下以博物馆为主题词的科研文献成果概况、科研机构分布及研究热点词与其研究发展趋势。经分析得知,该学科下以博物馆为主题的研究可以分为两个阶段:第一阶段(1996-2008年)主要是博物馆文献资源的开发与利用、博物馆与图书馆文献资源的开发与利用、博物馆古籍保护管理工作以及古籍文献等主题。第二阶段(2009-2019年)主要探讨三馆馆际合作的资源整合路径、数字资源整合理论模式与合作机制等的研究,并结合相关文献内容,深入探讨以博物馆为主题的研究重点,基于此,我国图情档学科应以博物馆中丰富多样的文化信息资源为视角,开展涵盖档案馆、图书馆、博物馆的全种类、全范围的全文化信息数字资源整合。最后,本文围绕数字资源整合这一具有影响力的研究热点,探讨如何从图情档学科的角度出发,有效地涵盖博物馆,构建以图书馆、档案馆、博物馆三馆为主体的数字资源整合模式与机制,建立为公众文化精神需求服务的信息共享平台。  相似文献

The paper provides the results of the first phase of the research project Trust and Authority in Scholarly Communications in the Light of the Digital Transition. It provides for an examination of the behaviours and attitudes of academic researchers as producers and consumers of scholarly information resources in the digital era in respect to how they determine authority and trustworthiness in the sources they use, cite, and publish in. The first phase of the study utilized focus groups to formulate research questions for the project as a whole. It provided the direction for the literature review, interviews, and questionnaires studies that would follow. Fourteen focus groups were held in the UK and US in order to obtain this information. A total of 66 science and social science researchers participated. The main findings were: (a) researchers play down difficulties of establishing trustworthiness, not because there are none, but because they have well‐developed methods of establishing trust; (b) citation‐derived metrics are becoming more important in regard to where researchers publish; (c) social media are ancillary to research, but are used for promotion of research and idea generation; (d) researchers are suspicious and confused about open access, but less so if produced by a traditional publisher; (e) there was a uniformity of perceptions/behaviour of researchers irrespective of differences in subject, country, and age; (f) although some early career researchers behave the same as their more senior colleagues this is because of a fear of the system: they actually think differently.  相似文献

This research explored the perceptions of university students about the credibility of information being shared on Facebook. The data were collected using an online questionnaire from university students who were Facebook users. A total of 325 usable responses were received which were analyzed using SPSS. The results revealed that these students perceive information shared on Facebook as credible and of good quality. The source credibility, medium credibility, and information quality had positive and significant relationships with each other. The age, social background, and educational level of students appeared to predict the credibility of information shared on Facebook. These results are useful for information professionals and social media managers in extent to understand and cater to the demands of information consumers. These findings would also be helpful for teachers, information providers, and researchers to understand the perspectives of developing countries' students on the credibility of social media information. Furthermore, this study is supposed to be a valuable addition in existing literature which could provide guidelines for novice researchers, interested in exploring the area, especially in the context of Facebook users in a developing country's context.  相似文献

Librarians have traditionally facilitated research development resulting in grants through performing biomedical literature searches for researchers. The librarians at the Taubman Health Sciences Library of the University of Michigan have taken additional steps forward by instituting a proactive approach to assisting investigators. To accomplish this, the librarians have taken part in a collaborative effort with the University of Michigan Medical School Office of Research. Through this partnership, both units have created and adopted various techniques intended to facilitate the submission of grants, thus allowing researchers more time to conduct their primary activities.  相似文献
