A variety of bibliometric measures have been proposed to quantify the impact of researchers and their work. The h-index is a notable and widely used example which aims to improve over simple metrics such as raw counts of papers or citations. However, a limitation of this measure is that it considers authors in isolation and does not account for contributions through a collaborative team. To address this, we propose a natural variant that we dub the Social h-index. The idea is to redistribute the h-index score to reflect an individual's impact on the research community. In addition to describing this new measure, we provide examples, discuss its properties, and contrast with other measures. 相似文献

Today, it is not clear how the impact of research on other areas of society than science should be measured. While peer review and bibliometrics have become standard methods for measuring the impact of research in science, there is not yet an accepted framework within which to measure societal impact. Alternative metrics (called altmetrics to distinguish them from bibliometrics) are considered an interesting option for assessing the societal impact of research, as they offer new ways to measure (public) engagement with research output. Altmetrics is a term to describe web-based metrics for the impact of publications and other scholarly material by using data from social media platforms (e.g. Twitter or Mendeley). This overview of studies explores the potential of altmetrics for measuring societal impact. It deals with the definition and classification of altmetrics. Furthermore, their benefits and disadvantages for measuring impact are discussed. 相似文献

This study established a technological impact factor (TIF) derived from journal impact factor (JIF), which is proposed to evaluate journals from the aspect of practical innovation. This impact factor mainly examines the influence of journal articles on patents by calculating the number of patents cited to a journal divided by the number of articles published in that particular journal. The values of TIF for five-year (TIF5) and ten-year (TIF10) periods at the journal level and aggregated TIF values (TIFAGG_5 and TIFAGG_10) at the category level were provided and compared to the JIF. The results reveal that journals with higher TIF values showed varied performances in the JCR, while the top ten journals on JIF5 showed consistent good performance in TIFs. Journals in three selected categories – Electrical & Electronic Engineering, Research & Experimental Medicine, and Organic Chemistry – showed that TIF5 and TIF10 values are not strongly correlated with JIF5. Thus, TIFs can provide a new indicator for evaluating journals from the aspect of practical innovation. 相似文献

关于传媒影响力的诠释——对传媒产业本质的一种探讨 总被引：24，自引：0，他引：24
传媒影响力本质上就是它作为资讯传播渠道而对其受众的社会认知、社会判断、社会决策及相关的社会行为所打上的属于自己的那种“渠道烙印”。传媒影响力的发生和建构 ,主要依赖于传媒在三个环节的资源配置和运作模式———即接触环节 :吸引注意的关键在于传媒内容和形式的极致化操作 ;保持环节 :构筑受众之于传媒的行为忠诚度和情感忠诚度 ;提升环节 :选择最具社会行动能力的人群、占据最重要的市场制高点、按照社会实践的“问题单”的优先顺序定制自己的产品。本文是作者就以往对传媒影响力问题的更深入思考 相似文献

欧盟数据保护影响评估制度起源于隐私影响评估制度,数据保护影响评估制度的实施主体是数据控制者,规制对象是具有高风险的数据处理行为,具体流程包括审查、咨询、评估、报告和保障及复审五个阶段。欧盟数据保护影响评估制度对数据保护有风险防控作用,企业可因此更被消费者信赖。数据保护影响评估制度有指导性规范与行业自律结合、强制性义务两种模式。欧盟数据保护影响评估制度对于我国个人信息和重要数据安全风险评估制度配套法规的制定和落地,尤其是在安全风险评估的适用范围、评估性质、流程设计与机构设置等方面,具有重要的借鉴意义。图3。表1。参考文献19。 相似文献

[目的/意义] 分析JCR最新公布的"影响因子百分位"指标的特点以及其对期刊评价的影响。[方法/过程] 从影响因子百分位的内涵分析入手,比较其与影响因子的统计学特征,在因子分析的基础上,采用多元回归和分位数回归研究影响因子百分位与其他文献计量指标之间的关系,同时采用Spearman相关系数分析其与其他文献计量指标的关系。[结果/结论] 研究结果表明,影响因子百分位改变了影响因子的统计学特征;影响因子较低的一些期刊,转换成影响因子百分位后相对值更低,其他期刊转换成影响因子百分位后相对值更高;影响因子百分位与其他文献计量指标相关程度中等;当影响因子百分位较低时,影响因子相关指标的弹性系数较高,当影响因子百分位处于中等时,总量指标及特征因子指标的回归系数较低;影响因子百分位并不适宜作为其中一个指标用于期刊多属性评价。 相似文献

Sara E. Grozanick 《Public Services Quarterly》2013,9(4):389-399
The Future Voices in Public Services column is a forum for students in graduate library and information science programs to discuss key issues they see in academic library public services, to envision what they feel librarians in public service have to offer to academia, to tell us of their visions for the profession, or to tell us of research that is going on in library schools. We hope to provide fresh perspectives from those entering our field, in both the United States and other countries. Interested faculty of graduate library and information science programs who would like their students’ ideas represented in these pages are invited to contact Nancy H. Dewald at nxd7@psu.edu. Sara E. Grozanick is a student in the School of Information and Library Science (SILS) at the Pratt Institute, New York. Recognizing the significance of the Open Access movement to the advancement of scholarship, here she writes a bibliographic essay on research into the citation impact of open access journal articles. The School of Information and Library Science (SILS) at the Pratt Institute located in Manhattan and offering LIS education since 1890, features a curriculum based on Cultural Informatics and World Information, Society & Environments (WISE). The program reflects the arts orientation of Pratt and its alliance with cultural institutions in the city such as the Metropolitan Museum of Art, New York Public Library, and the Brooklyn Museum. The nearly 400 students who attend Pratt-SILS onsite have the opportunity to select a master's program resulting in a MS in Library and Information Science or a MSLIS with Library Media Specialist Certification, archives certificate, or dual degree programs resulting in a MSLIS/MS History of Art, a MSLIS/MFA Digital Arts, or a MSLIS/JD with Brooklyn Law School. ***** 相似文献

Increasing political and financial support for scientific research in the Middle East requires academic and research communities in the region to demonstrate the visibility and impact of their scientific output. However, for countries with smaller scientific communities or lack of detailed information on their scientific production, the use of common metrics of scientific impact (e.g., number of papers, impact factor, h-index, etc.) may fail to reveal their true ability to produce high quality research, and thus guarantee the wanted societal support. In such cases, identifying and highlighting outstanding papers produced by national institutions or scientists may be another way to demonstrate scientific capacity and impact. In this context, this work aims to provide an overview of champion works (papers that have received over 1,000 citations) produced by Middle East countries. This analysis focuses on science, medicine, and technology papers featured in the Science Citation Index Expanded of Web of Science. The authors identified 213 champion works authored by Middle East scientists published since the 1970s. Israel is currently the leading nation in the Middle East in terms of published champion works, but at least one such work was identified for the majority of countries in the region. Middle East champion works were published on a diverse range of subject categories and often featured in the top journals worldwide (e.g., Science, Nature, etc.). The top institutions in the Middle East authoring champion works and their leading collaborating countries worldwide are listed, and the role of international scientific collaborations in achieving these highly cited papers is highlighted. 相似文献

The aim of this study is to introduce two groups of impact indicators, Weighted Altmetric Impact (WAI) and Inverse Altmetric Impact (IAI). WAI is based in weights from the contributions of each metric to different components or impact dimensions (Principal Component Analysis). IAI is calculated according to the inverse prevalence of each metric in different impact dimensions (TF/IDF). These indicators were tested against 29,500 articles, using metrics from Altmetric.com, PlumX and CED. Altmetric Attention Score (AAScore) was also obtained to compare the resulting scores. Several statistical analyses were applied to value the advantages and limitations of these indicators. Frequency distributions showed that each group of metrics (Scientific Impact, Media Impact and Usage Impact) follows power law trends although with particular patterns. Correlation matrices have depicted associations between metrics and indicators. Multidimensional scaling (MDS) has plotted these interactions to visualize distances between indicators and metrics in each dimension. The 2018 Altmetric Top 100 was used to distinguish differences between rankings from AAScore and the proposed indicators. The paper concludes that the theoretical assumptions of dimensions and prevalence are suitable criteria to design transparent and reproducible impact indicators. 相似文献

利用Google的PageRank原理进行期刊引文分析,提出期刊在引文网络中的影响力测度指标--引文网络影响力序位(Journal Impact Rank in Citation Net,Impact Rank或IR).通过对118种生物学领域的期刊进行期刊引文网络影响力测度,并将IR结果与JCR提供的影响因子(Impact Factor, IF)值进行统计学分析以考察二者的相关性和差异性.结果表明,IR值与IF值的相关性较弱,其差异性具有统计学意义.分析其原因,IR考虑了引证期刊的权重和期刊间的相互影响,更适于反映期刊在其相关学科或领域的引文网络中的相对影响力;IF值因其实质上是期刊论文篇均被引频次,其计算不考虑期刊之间的相互联系和引证期刊的权威性,因而更适用于期刊自身的纵向评价;IR与IF从两种不同角度评价期刊影响力,可互为补充. 相似文献
