现有的学术期刊评价缺乏同时对期刊影响力与期刊知识扩散能力的评价,为此本文构建了学术期刊影响深度与影响宽度的评价框架,并提出期刊综合影响指数的概念:采用被引频次、影响因子、h指数评价期刊影响深度,采用扩散因子、新扩散因子评价期刊影响宽度,通过期刊影响宽度与影响深度计算期刊综合影响因子。利用中国知网引文数据库(CNKI)的引文数据,对图书馆情报与文献学CSSCI期刊的研究表明:期刊影响深度、期刊影响宽度、期刊综合影响指数均服从正态分布,统计指标特征相近;期刊综合影响指数与评价指标正相关,说明该指标评价是稳健的;期刊综合影响指数与自引率、载文量无关,可以防止指标人为操纵。表5。参考文献18。 相似文献

针对Z指数不能实现跨学科领域期刊评价的缺陷,文章通过引入学科规范化引文影响力修正不同学科的引用差异,改进Z指数并提出ZCNCI指数。通过分析ZCNCI指数与Z指数、P指数、SNIP、标准化特征因子、影响因子百分位等指标的相关性和差异性,验证ZCNCI指数跨学科期刊评价的效力。结果表明,ZCNCI指数延续了Z指数综合反映期刊数量、质量和被引分布特征的优势,与Z指数、P指数、标准化特征因子的相关性较高,且克服了SNIP、影响因子百分位的评价缺陷,在跨学科期刊评价中的综合表现较好。ZCNCI指数具有跨学科期刊评价效力,可用于跨学科期刊评价。 相似文献

为了验证《中国学术期刊(光盘版)》电子杂志社提出的新型期刊评价指标——期刊影响力指数(Journal Clout Index,CI)的科学性,首先采用JCR数据分析影响因子(IF)与5年影响因子(IF5)、IF与即年指标(IM)、IF与总被引频次(TC)之间的相关性,得出结论:IF、IF5、IM是相关性显著的同类指标,IF与TC的相关性较弱;因而认为,TC和IF是可用来评价期刊影响力的主要指标,基于这2个指标的综合评价指标——期刊影响力指数(CI)具有合理性.进一步实证分析了CI这一综合指标对国际期刊的排序结果比采用单一指标——影响因子(IF)排序更符合实际经验认识. 相似文献

学术期刊"退稿率"定义的反思 总被引：3，自引：0，他引：3
学术期刊之退稿率向来为学术界采具同侪评阅(peer review)要求下,所并随产生与要求呈具的资料。它通常亦被用作证明期刊品质控制良窳之标准之一。然而,因定义与界定不清,使得退稿率之实质意义并不如预期,也有失公允。本文即为举证退稿率要求之不当,并提出适当之改进建议,俾使学术期刊评价能更合乎公平客观。 相似文献

Assessing the scholarly impact of academic institutions has become increasingly important. The achievements of editorial board members can create benchmarks for research excellence and can be used to evaluate both individual and institutional performance. This paper proposes a new method based on journal editor data for assessing an institution’s scholarly impact. In this paper, a journal editorship index (JEI) that simultaneously accounts for the journal rating (JR), editor title (ET), and board size (BS) is constructed. We assess the scholarly impact of economics institutions based on the editorial boards of 211 economics journals (which include 8640 editorial board members) in the ABS Academic Journal Guide. Three indices (JEI/ET, JEI/JR, and JEI/BS) are also used to rank the institutions. It was found that there was only a slight change in the relative institutional rankings using the JEI/ET and JEI/BS compared to the JEI. The BS and ET weight factors did not have a substantial influence on the ranking of institutions. It was also found that the journal rating weight factor had a large effect on the ranking of institutions. This paper presents an alternative approach to using editorial board memberships as the basis for assessing the scholarly impact of economics institutions. 相似文献

This paper presents a case study of an advisory role that librarians successfully developed with faculty editors to increase the visibility and readership of an open access scholarly publication. The study represents an example of how expertise among liaison librarians and other library service professionals can be leveraged in new consultancy roles in support of evolving library service models. It also depicts local application of a hybrid model for librarianship that combines the functional specialist and subject librarian liaison roles in implementing advisory activities and recommendations. The liaison librarians successfully used their knowledge of scholarly communications and applied innovative bibliometric analysis to help enhance the discoverability and user experience of an online journal publication. The librarians made specific recommendations for optimizing journal website content organization, search functionality, metadata standards and marketing opportunities that were subsequently implemented by the editors and platform managers. The faculty editor places a high value on these recommendations, and the librarian advisory role continues to develop. Our study also outlines many of the essential considerations that scholar-editors and librarian advisors can use to help implement open access scholarly publishing projects successfully. 相似文献

There are many indicators of journal quality and prestige. Although acceptance rates are discussed anecdotally, there has been little systematic exploration of the relationship between acceptance rates and other journal measures. This study examines the variability of acceptance rates for a set of 5094 journals in five disciplines and the relationship between acceptance rates and JCR measures for 1301 journals. The results show statistically significant differences in acceptance rates by discipline, country affiliation of the editor, and number of reviewers per article. Negative correlations are found between acceptance rates and citation-based indicators. Positive correlations are found with journal age. These relationships are most pronounced in the most selective journals and vary by discipline. Open access journals were found to have statistically significantly higher acceptance rates than non-open access journals. Implications in light of changes in the scholarly communication system are discussed. 相似文献

This paper reports on a study of social scientists’ information seeking and use of scholarly journals to support scholarly communication and information needs. The goals of the study are: to explore the characteristics of information needs for social scientists; to discuss the importance of scholarly journals to social scientists and their information seeking and access means; to identify article reading patterns of social scientists; and to make comparisons between scholarly journals use and reading patterns of social scientists and other scientists in Taiwan and the USA. The author used a questionnaire survey and interview methods to investigate the information seeking, use and reading of scholarly journals, and article deep reading patterns of social scientists. The target population was social science faculty members from National Cheng-chi University in Taiwan. The article explores the characteristics of information needs for social scientists and shows that scholarly journals are important information resources for university social science faculty. Social science faculty in Taiwan use scholarly journals in multiple languages, mainly English, Chinese, German, and Japanese, which is different from scientists in the United States. In addition, they use electronic journals more than print journals. The number of article readings by social science faculty members was approximately 195 readings per year and nearly 440 h were spent reading per year. In contrast to scientists in the United States, the social scientists in Taiwan read fewer readings, spent more time reading, and read older articles. In addition, the study identifies article reading patterns of social scientists and proposes a six-type taxonomy of article deep reading. The study reports the scholarly journal use and reading behavior model of social scientists and shows there are some differences in scholarly journal seeking and use by social science faculty in Taiwan and scientists in the United States. Further studies of scholarly journal and electronic journal use and reading by social scientists across countries, subject disciplines, and languages of journals are needed. 相似文献
