p 指数运用于人才评价的有效性实证研究 总被引:2,自引:0,他引:2
h指数用于高发文、高引用的学者评价是有效的,但对低发文、高引用的学者进行评价存在缺陷,且数值易于雷同,不易区分。p指数在学者研究绩效评价方面具有同h指数相一致的维度,它不仅考虑学者的被引次数(C),而且考虑学者的研究质量指标——平均被引率(C/N)。以图书情报与文献学科领域49位专家为例,对比分析专家的发文量(N)、被引次数(C)、平均被引率、专家h指标、g指数、p指数,并进行相关性分析。结论:p指数优于现有的h指数、g指数,更具有评价的合理性,应在更大范围内进一步使用。 相似文献

[目的/意义]科研合作是不同科研主体之间围绕特定科学问题开展研究的协同研究工作,以实现科研主体间的优势互补。国际科研合作对促进科研绩效具有重要意义。了解当前国际科研合作对科研绩效影响研究的现状,为未来进一步开展该方面的研究提供参考和借鉴。[方法/过程]论文在界定国际科研合作、科研绩效两个重要概念的基础上,从研究层次、分析指标、分析方法3个维度对国际科研合作对科研绩效影响研究的论文进行梳理。[结果/结论]分析发现,目前该研究领域成果丰富,国内外学者主要从宏观(国家、地区或区域等)、中观(领域或机构、团队等)、微观(科研人员个体)3个层面,通过简单计数类和单一比值类国际科研合作指标以及科研产出数量类、科研产出质量类和h指标类科研绩效指标,采用文献计量学方法、社会网络分析方法及统计学分析的方法对国际科研合作对科研绩效的影响进行探析。未来需加强:科学家层面的研究,拓宽更多科研合作行为的分析;表征科研合作和科研绩效综合类指标的探索;针对性分析模型的创建,并对一些具有重要意义的变量进行控制。 相似文献

本文对新近提出的学术迹和影响矩指标应用于单篇论著的评价效果进行比较研究,以JASIST 2005—2014年间发表的25篇高被引论文和ASTROPHYSICAL JOURNAL 2011—2014年间发表的24篇高被引论文为两个样本集,研究学术迹和影响矩相对于总被引数和h指数等学术评价指标的异同,发现各指标排序既具有一定相关性,也呈现出一定独立性,说明这些指标均有独立存在价值,而学术迹和影响矩能提供更全面的测度信息。图3。表6。参考文献25。附录2。 相似文献

Ever more frequently, governments have decided to implement policy measures intended to foster and reward excellence in scientific research. This is in fact the intended purpose of national research assessment exercises. These are typically based on the analysis of the quality of the best research products; however, a different approach to analysis and intervention is based on the measure of productivity of the individual scientists, meaning the overall impact of their entire scientific production over the period under observation. This work analyzes the convergence of the two approaches, asking if and to what measure the most productive scientists achieve highly cited articles; or vice versa, what share of highly cited articles is achieved by scientists that are “non-top” for productivity. To do this we use bibliometric indicators, applied to the 2004–2008 publications authored by academics of Italian universities and indexed in the Web of Science. 相似文献

基于CSSCI的《中国图书馆学报》h指数及核心作者测定 总被引:16,自引:0,他引:16
h指数是2005年由美国J.E.Hirsch教授提出的新的科学评价指标。h指数已在评价科学家个人学术绩效及学术期刊等方面得到广泛应用。采用h指数新方法对《中国图书馆学报》进行评价,结果表明,该刊h指数值高达30。这在已知的中国期刊h指数中是最高者。 相似文献

为了揭示“h指数族”各项指数的相关性特点,对山东省内57所本科高校图书馆科研影响力进行综合实证研究,为图书馆工作者及相关机构进行馆际科研评价、交流和培训等提供决策依据。文章以《中国引文数据库》为数据源,用“h指数族”各项指数对评价机构在1996--201O年的论文数量和总被引频次进行统计分析。结论如下:鲁东大学图书馆h指数族取值特性异常显著;烟台大学图书馆等h指数族排名位次靠前;泰山医学院图书馆具备相当数量的潜在高被引论文,预期其科研影响力将会有显著提升。h指数族与论文数量和被引频次之间呈幂律关系,h指数族两两之间呈线性关系。图书馆h指数族取值随着图书馆论文数量和总被引频次的增长存在“规模效益递减”现象;图书馆应该密切关注能提升其g指数的潜在高被引论文,从而实现提升h指数和s指数、不断提高科研影响力的愿望。 相似文献

The increasing importance of research assessment is but one factor within the ever-changing scholarly communication landscape that is challenging libraries to develop new services to serve the needs of their academic communities. Institutional budget allocations, grant funding, and faculty tenure and promotion increasingly depend on performance indicators, including bibliometrics such as citation counts, impact factors, the h-index, and other quantitative measurements of research output. With their longstanding expertise in collecting, categorizing, and analyzing data, not to mention their familiarity with scholarly databases and indexes tracking cited references, librarians are well qualified to meet the emerging demand for bibliometrics services. 相似文献

基于h指数:课题组研究力评估的量化指标 总被引:1,自引:0,他引:1
讨论应用h指数评价科学研究课题组研究实力问题,提出课题组核心研究力评价模型和课题组综合研究实力评价模型,认为把课题组的核心研究力指数和课题组综合研究力指数作为科研评估中的一项量化指标,可以在一定程度上克服传统评价方法的一些缺陷。 相似文献

The purpose of this article is to come up with a valid categorization and to examine the performance and properties of a wide range of h-type indices presented recently in the relevant literature. By exploratory factor analysis (EFA) we study the relationship between the h-index, its variants, and some standard bibliometric indicators of 26 physicists compiled from the Science Citation Index in the Web of Science. 相似文献

论秦朝图书与档案的分野及其“以法治国”的行政取向 总被引:1,自引:0,他引:1
There are two major kinds of official collected books in Qin Dynasty. One is books which are to meet the needs of Doctor officials. The other is archives which are to meet the needs of law officials. And archives are the emphasis of official collected books in Qin Dynasty. Accordingly, archives are also the emphasis of official literature sorting in Qin Dynasty. It is different from the situation that books are the emphasis of official literature sorting in Han Dynasty. Administrative operation in Qin Dynasty is based on collection and utilization of official collected books. Therefore, Qin people’s different attitude towards books and archives can reflect the change of both Doctor officials’ and law officials’ political status. It can also reflect the administrative nature of Qin Dynasty, i.e. “rule country by law”. 相似文献

[目的/意义]很多学科服务机构已经把学科数据的定期分析和提供学科报告作为学科服务的重要手段,但这种学科数据分析报告服务仅具有周期性,并不能及时跟踪动态变化的学科数据。本研究的目的是以h指数分析为例,对学者影响力进行动态追踪和监测,探索一种基于动态数据整合的面向预测的新型学科服务模式。[方法/过程]通过对国内和国外两个研究团队h指数发展、逐年变化趋势进行文献计量分析,获取团队成员自有成果发表年以来逐年的论文数量及其引用数据,并计算累积被引次数,逐年提取h指数。[结果/结论]团队成员中h指数增长趋势轨迹各不相同,需结合各成员任职年限、h指数增长率等数据对其在团队中的作用进行判断,论文最后对不同的h指数变化趋势在科研管理中的作用进行总结和概括。 相似文献

The results from analyzing the scientific output of scientists from the Novosibirsk oblast’ are given based on works published
in 2005–2009. The analysis was carried out using the data and potential of the Web of Science (WoS) and, in particular, information
about domestic and foreign science foundations that supported particular studies, Journal Citation Reports, HistCite software,
and certain additional data that included official statistics from Rosstat and involved indicators derived from the journal impact factor and the aggregate impact factor of the WoS knowledge category. The publications by the scientists from the oblast’ were distributed according to 133 WoS knowledge categories. Research
in certain trends in 48 WoS knowledge categories carried out in the oblast’ is in no way inferior to and very often is even
better than the global science standards. More than 50% of the publications were sponsored by domestic and foreign science
foundations: the scientific quality of these works was considerably higher than that of the unsponsored studies. The coauthors
of the articles published by scientists of the oblast’ in the period were their colleagues from 83 countries. R & D costs
in the Novosibirsk oblast’ are used quite efficiently: in 2009 the publications by the scientists of the oblast’ accounted
for more than 9% of the entire amount of works published all over Russia, while internal research and development expenses
were only 2.5% of such expenses nationwide. 相似文献

A large number of overseas elites were brought back to China by the policy in the past decade. However, name disambiguation defied investigations on the relationship between their mobility and research performance. By taking advantage of the ORCID website and applying causal inference strategies, we investigated 2489 China-connected scientists’ academic performance in the Web of Science database in terms of their job mobility, including 1388 scientists who moved to China the treatment group, and 1101 scientists with a possibility to move to China the control group. The results show that first, scientists moving to China have a new growth pattern where both their productivity and the rates of being corresponding authors in publications grew more rapidly than before; however, they made fewer contributions to the four top journals, Nature, Science, Cell, and PNAS. Second, the research performance of the scientists is affected by the time of mobility towards China, the countries from which they moved, and the disciplines of their publications. Last, China now maintains symmetrical inflow-outflow patterns with most countries, especially developed countries in Europe and North America, with only a few exceptions (e.g., Pakistan). 相似文献
