Google Scholar's Coverage of the Engineering Literature 10 years Later     

Carmen Cole  Angela R. Davis  Vanessa Eyer  John J. Meier 《The Journal of Academic Librarianship》2018,44(3):419-425

In 2008 Meier and Conkling first tested Google Scholar's coverage of the engineering literature against citations gathered from the Compendex database. Since that time, other studies have used the same methodology and found improvement in Google Scholar's coverage. This study uses engineering dissertations from Proquest Dissertations & Theses to create a data set of citations for the comparison of fee-based databases, Compendex and Scopus, against Google Scholar. From 1950 to 2017 Google Scholar outperformed both Compendex and Scopus in discoverability of citations in nine engineering subjects. These results have implications for collection management and information literacy program planning for librarians.  相似文献

Supreme Court Review (1960–2009): A Bibliometrical Study     

Joel Fishman 《Legal Reference Services Quarterly》2018,37(1):1-10

Supreme Court Review is a faculty-edited legal periodical published by the University of Chicago Law School. This periodical is a highly read and cited law review in law, history, and political science. This article applies bibliometrics to a study of the 438 articles that are published in the periodical over a 50-year period. It is analysis of the number of articles by volume, pages, footnotes, authorship by sex, by individual, by institution, and most-cited articles.  相似文献   

On the same page: Improving the connection between public services units in academic libraries     

Elizabeth Marcus  Malti Turnbull 《College & Undergraduate Libraries》2018,25(2):101-109

Communication quality between public service units in academic libraries can make the difference between mediocre and exceptional service. If units do not communicate well, patrons may receive inaccurate information and experience short-term frustration, leading to long-term damage to the library's reputation. Poor communication creates adverse effects on employees through decreased productivity, negative work culture, and low morale. This article explores the importance of quality communication through a review of the literature and a case study at one academic library. The authors share practical communication improvement strategies for libraries of every size and fiscal ability.  相似文献   

Author ranking evaluation at scale     

Marcel Dunaiski  Jaco Geldenhuys  Willem Visser 《Journal of Informetrics》2018,12(3):679-702

We evaluate author impact indicators and ranking algorithms on two publication databases using large test data sets of well-established researchers. The test data consists of (1) ACM fellowship and (2) various life-time achievement awards. We also evaluate different approaches of dividing credit of papers among co-authors and analyse the impact of self-citations. Furthermore, we evaluate different graph normalisation approaches for when PageRank is computed on author citation graphs.We find that PageRank outperforms citation counts in identifying well-established researchers. This holds true when PageRank is computed on author citation graphs but also when PageRank is computed on paper graphs and paper scores are divided among co-authors. In general, the best results are obtained when co-authors receive an equal share of a paper's score, independent of which impact indicator is used to compute paper scores. The results also show that removing author self-citations improves the results of most ranking metrics. Lastly, we find that it is more important to personalise the PageRank algorithm appropriately on the paper level than deciding whether to include or exclude self-citations. However, on the author level, we find that author graph normalisation is more important than personalisation.  相似文献   

Four pitfalls in normalizing citation indicators: An investigation of ESI’s selection of highly cited papers     

Zhigang Hu  Wencan Tian  Shenmeng Xu  Chunbo Zhang  Xianwen Wang 《Journal of Informetrics》2018,12(4):1133-1145

InCites Essential Science Indicators is becoming increasingly used to identify top-performing research and evaluate the impact of institutes. Unfortunately, our study shows that ESI indicators, as well as other normalized citation indicators, have the following flaws. First, the publication month and the online-to-print delay affect a paper’s probability of becoming a Highly Cited Paper (HCP). Papers published in the earlier months of the year are more likely to accumulate enough citation counts to rank at the top 1% compared with those published in later months of the year. Papers with longer online-to-print delays have an apparent advantage for being selected as HCPs. Research field normalizations lead to the third pitfall. Different research fields have different citation thresholds for HCPs, making research field classification important for a journal. In addition, the uniform thresholds for both articles and reviews in ESI affect the reliability of HCP selection because, on average, reviews tend to have higher citation rates than articles. ESI’s selection of HCPs provides an intuitive feel for the problems of normalized citation impact indicators, such as those provided in InCites and SciVal.  相似文献   

Dimensions: A competitor to Scopus and the Web of Science?     

Mike Thelwall 《Journal of Informetrics》2018,12(2):430-435

Dimensions is a partly free scholarly database launched by Digital Science in January 2018. Dimensions includes journal articles and citation counts, making it a potential new source of impact data. This article explores the value of Dimensions from an impact assessment perspective with an examination of Food Science research 2008–2018 and a random sample of 10,000 Scopus articles from 2012. The results include high correlations between citation counts from Scopus and Dimensions (0.96 by narrow field in 2012) as well as similar average counts. Almost all Scopus articles with DOIs were found in Dimensions (97% in 2012). Thus, the scholarly database component of Dimensions seems to be a plausible alternative to Scopus and the Web of Science for general citation analyses and for citation data in support of some types of research evaluations.  相似文献   

Technological research in the EU is less efficient than the world average. EU research policy risks Europeans’ future     

Alonso Rodríguez-Navarro  Ricardo Brito 《Journal of Informetrics》2018,12(3):718-731

We have studied the efficiency of research in the EU by a percentile-based citation approach that analyzes the distribution of country papers among the world papers. Going up in the citation scale, the frequency of papers from efficient countries increases while the frequency from inefficient countries decreases. In the percentile-based approach, this trend, which is uniform at any citation level, is measured by the e_p index that equals the P_{top 1%}/P_{top 10%} ratio. By using the e_p index we demonstrate that EU research on fast-evolving technological topics is less efficient than the world average and that the EU is far from being able to compete with the most advanced countries. The e_p index also shows that the USA is well ahead of the EU in both fast- and slow-evolving technologies, which suggests that the advantage of the USA over the EU in innovation is due to low research efficiency in the EU. In accord with some previous studies, our results show that the European Commission’s ongoing claims about the excellence of EU research are based on a wrong diagnosis. The EU must focus its research policy on the improvement of its inefficient research. Otherwise, the future of Europeans is at risk.  相似文献   

中巴建交六十年:双边关系回顾与思考     

孙红旗 《徐州师范大学学报(哲学社会科学版)》2011,37(3):6-11

自1951年中国与巴基斯坦建立外交关系以来,至2011年,双边关系迎来了60周年。回顾过去跨世纪的60年,中巴关系在几个发展阶段都呈现出一些共同的特征,无论双方国内政治格局如何变动,无论国际风云如何变幻,中国和巴基斯坦都经受住了时间的检验,将"好邻居、好朋友、好伙伴、好兄弟"的国家和人民之间的关系不断推向更高的阶段,最终形成"全天候"和"全方位"的战略合作关系,成为当代国际关系的典范,也成为维护地区和世界和平、稳定与安全的重要力量。60年的中巴交往积累了丰富的弥足珍贵的经验,可以概括为:以"和谐世界"、"和而不同"的哲学思想为出发点,互相尊重,平等相待,高度信任;从全球化角度来审视和处理两国关系是中巴能够"以不变应万变"、长期保持"全天候"和"全方位"战略合作的最佳视域;以维护对方国家核心利益为基轴,在事关领土完整、民族安全等重大问题上相互理解和支持;与时俱进,扩大互利共赢的双边经贸合作是巩固和拓展两国"特殊关系"的基石;频繁的高端互访和各领域、各层次友好往来是中巴关系长盛不衰、保持活力的根本源泉。事实上,这种非同一般的关系已经远远超越双边和地区范畴,对全世界都有借鉴意义。  相似文献
