A proposal is made in this paper for a broadening of perspective in evaluative bibliometrics by complementing the (standard) times cited with a cited reference analysis for a field-specific citation impact measurement. The times cited approach counts the citations of a given publication set. In contrast, we change the perspective and start by selecting all papers dealing with a specific research topic or field (the example in this study is research on Aspirin). Then we extract all cited references from the papers of this field-specific publication set and analyse which papers, scientists, and journals have been cited most often. In this study, we use the Chemical Abstracts registry number to select the publications for a specific field. However, the cited reference approach can be used with any other field classification system proposed up to now. 相似文献

In the Essential Science Indicators (Thomson Reuters), a research front exists to the h index (entitled “GOOGLE SCHOLAR H-INDEX; SCIENCE CITATION INDEX; GENERALIZED HIRSCH H-INDEX; H INDEX; GOOGLE SCHOLAR CITATIONS”) consisting of a group of highly cited papers. We used HistCite to analyze the structure and relationships of the 45 papers forming the h index research front. Since we were interested in the topics of research on the h index at the front, we classified each paper according to its main topic. Six topics (inductively generated) were sufficient to classify the 45 papers: (1) citation database, (2) empirical validation study, (3) new application, (4) theoretical analysis, (5) new index development, and (6) literature review. 相似文献

Two distinguishing features of the New Labour Government have been its focus on regionalism and the establishment of a department of state, the Department for Culture, Media and Sport (DCMS), explicitly dedicated to ‘cultural’ policy. This paper tracks the development of a new set of regional cultural organizations, the Regional Cultural Consortiums (RCCs). These were established to contribute to regional development and to deliver the DCMS's national policy goals. The paper examines the RCCs' remit, challenges, achievements and prospects, and locates these in wider debates about evidence-based policy and continuity and change in cultural and regional policy. Particular consideration is given to the RCCs' research and data collection activities and their role in developing a move towards improved capacity in regional cultural research and data collection. 相似文献

This paper presents the first meta-analysis of studies that computed correlations between the h index and variants of the h index (such as the g index; in total 37 different variants) that have been proposed and discussed in the literature. A high correlation between the h index and its variants would indicate that the h index variants hardly provide added information to the h index. This meta-analysis included 135 correlation coefficients from 32 studies. The studies were based on a total sample size of N = 9005; on average, each study had a sample size of n = 257. The results of a three-level cross-classified mixed-effects meta-analysis show a high correlation between the h index and its variants: Depending on the model, the mean correlation coefficient varies between .8 and .9. This means that there is redundancy between most of the h index variants and the h index. There is a statistically significant study-to-study variation of the correlation coefficients in the information they yield. The lowest correlation coefficients with the h index are found for the h index variants MII and m index. Hence, these h index variants make a non-redundant contribution to the h index. 相似文献

新冠疫情全球爆发和防控,彰显科学技术之运用在应对公共卫生危机中的重要作用.不同国家和地区在疫情应对中的差别,反映出在技术文化尤其是技术治理方面的差异,包括技术范式、技术实践和疫期生活等方面的不同.同时,在意识形态和政治差异背景下,世界日益走向全球性技术治理,对此需要更深入的研究和反思.本文主要以中国、德国和美国的情况为例,比较世界不同国家和地区运用科技应对疫情的差异,理解世界技术文化的多元性,以期帮助提升各国技术治理的水平. 相似文献
