This paper aims to investigate the practices of Pakistani academic researchers with respect to using, citing, and publishing their scholarly work. The quantitative survey method adopted to collect data from local researchers was based on an instrument developed and used by CIBER. Their notions and practices involved in deciding trust and quality of scholarly journals were obtained. The findings revealed that national and institutional policies have significantly influenced their decisions regarding the publishing outlets. The credibility of indexing services was found to be an important factor in choosing the journal for publishing research. ISI Web of Science Impact Factor was not considered as the top source for determining quality and trustworthiness. This study is the first of its kind that targets the top two universities of the country. A comparison of the findings with another international study shows that some of the behavioural traits are compatible with scholars from less‐developed countries like India and China, while others are more similar to the ones from highly developed countries like USA and UK.  相似文献

Journal weighted impact factor: A proposal   总被引：3，自引：0，他引：3  
The impact factor of a journal reflects the frequency with which the journal's articles are cited. It is the best available measure of journal quality. For calculation of impact factor, we just count the number of citations, no matter how prestigious the citing journal is. We think that impact factor as a measure of journal quality, may be improved if in its calculation, we not only take into account the number of citations, but also incorporate a factor reflecting the prestige of the citing journals relative to the cited journal. In calculation of this proposed “weighted impact factor,” each citation has a coefficient (weight) the value of which is 1 if the citing journal is as prestigious as the cited journal; is >1 if the citing journal is more prestigious than the cited journal; and is <1 if the citing journal has a lower standing than the cited journal. In this way, journals receiving many citations from prestigious journals are considered prestigious themselves and those cited by low-status journals seek little credit. By considering both the number of citations and the prestige of the citing journals, we expect the weighted impact factor be a better scientometrics measure of journal quality.  相似文献

This study examines the extent of concentration in the journal publishing industry. A number of aspects are considered: publishers, journal impacts, countries, and languages. For journals indexed in JCR from 1997 to 2009, just 0.2% of publishers produce 50% of journals and articles, and 0.3% of publishers account for the top 50% of citations, impact factors and immediacy indices. More than a half of publishers in JCR are from four countries: USA, UK, Germany and Japan. In addition, more than a half of journals come from the USA and UK. Examining the publishers' interactions in terms of buying and selling journals shows the extent of change by acquisition, and the acquisition links between publishers. The findings confirm that the international market of journal publishing is essentially dominated by a few publishers.  相似文献

The preferences of the authors of Chinese library and information science (LIS) journal articles in citing Internet sources were investigated using eight premium Chinese LIS journals from Chinese Social Sciences Citation Index (the observation group) and 10 journals in other disciplines (the control group) from the same database from 1999 to 2008. A total of 252,881 citations were analyzed in terms of count, domain name, and citing purposes. The results show that (a) in comparison to the disciplines in the control group, LIS articles in Chinese journals indicated a strong preference for citing Internet sources, and this preference is increasing; (b) LIS articles did not seem to discriminate against domain names when citing Internet sources; and (c) LIS articles cited more Internet sources as evidence to support research results and conclusions. Excessive dependency on Internet sources may raise concerns over the quality, research ethics, and credibility of research publications. Chinese LIS researchers should place more emphasis on the disadvantages of Internet sources as supporting material. Guidelines and criteria to help researchers, journal editors, students, and librarians assess information on the Web need to be developed.  相似文献

Despite citation counts from Google Scholar (GS), Web of Science (WoS), and Scopus being widely consulted by researchers and sometimes used in research evaluations, there is no recent or systematic evidence about the differences between them. In response, this paper investigates 2,448,055 citations to 2299 English-language highly-cited documents from 252 GS subject categories published in 2006, comparing GS, the WoS Core Collection, and Scopus. GS consistently found the largest percentage of citations across all areas (93%–96%), far ahead of Scopus (35%–77%) and WoS (27%–73%). GS found nearly all the WoS (95%) and Scopus (92%) citations. Most citations found only by GS were from non-journal sources (48%–65%), including theses, books, conference papers, and unpublished materials. Many were non-English (19%–38%), and they tended to be much less cited than citing sources that were also in Scopus or WoS. Despite the many unique GS citing sources, Spearman correlations between citation counts in GS and WoS or Scopus are high (0.78-0.99). They are lower in the Humanities, and lower between GS and WoS than between GS and Scopus. The results suggest that in all areas GS citation data is essentially a superset of WoS and Scopus, with substantial extra coverage.  相似文献

The purpose of this study was to examine the relationship between publication rate, top journal publications and excellence during the first eight years of the career, and how well publication rate, top journal publications and highly cited publications during the first four years of the career can predict whether an author attain excellence in the fifth to the eighth year. The dataset consisted of publication track records of 406 early career mathematicians in the sub-field of number theory collected from the MathSciNet database. Logistic regression and dominance analysis was applied to the data. The major conclusions were (1) publication rate had a positive effect on excellence during the first eighth years of the career. However, those who publish many articles in top journals, which implicitly require a high publication count, had an even higher probability of attaining excellence. These results suggest that publishing in top journals is very important in the process of attaining excellence in the early career in addition to publishing many papers; and (2) a dominance analysis indicated that the number of top journal publications and highly cited publications during the first four years of the career were the most important predictors of who will attain excellence in the later career. The results are discussed in relation to indicator development and science policy.  相似文献

This study examines aspects of scholarly journal publishing in the Nordic countries. On average half of Nordic journals publish online. In most Nordic countries, commercial publishers predominate; however, in Finland the majority are society publishers. The number of open access journals is low, in line with international figures. There is concern to maintain local languages in journal publishing. A majority of the journals publishing in local languages are within social science, humanities, and arts; the STM sector publishes in English. English‐language publications are favoured in research assessments, international recognition, and impact, while the visibility of local‐language scholarly journals in international databases is low. The Nordbib program supports Nordic scholarly journals and fosters co‐operation with publishing companies and learned societies over migration to e‐publishing; it also supports open access. The article discusses future challenges for journal publishing, pointing out the problems of small journal publishers and the need for co‐operation between stakeholders.  相似文献

Do academic journals favor authors who share their institutional affiliation? To answer this question we examine citation counts, as a proxy for paper quality, for articles published in four leading international relations journals during the years 2000–2015. We compare citation counts for articles written by “in-group members” (authors affiliated with the journal’s publishing institution) versus “out-group members” (authors not affiliated with that institution). Articles written by in-group authors received 18% to 49% fewer Web of Science citations when published in their home journal (International Security or World Politics) vs. an unaffiliated journal, compared to out-group authors. These results are mainly driven by authors who received their PhDs from Harvard or MIT. The findings show evidence of a bias within some journals towards publishing papers by faculty from their home institution, at the expense of paper quality.  相似文献

Abstract

Using a scientometric approach, this study examines scholarly publications by library and information science (LIS) researchers affiliated with Iranian institutions that were published in non-Iranian journals and indexed in the Web of Science (WoS) database, together with publications in Iranian LIS journals from 1980 through 2016. The results show that Iranian authors published 538 LIS documents indexed in WoS and another 7,837 in national journals. The research article was the predominant document type at both the national and international levels. The total number of international publications in LIS by all countries was 313,449; Iran ranked 34th among the countries for publications in LIS.  相似文献

Bibliometricians have long recurred to citation counts to measure the impact of publications on the advancement of science. However, since the earliest days of the field, some scholars have questioned whether all citations should be worth the same, and have gone on to weight them by a variety of factors. However sophisticated the operationalization of the measures, the methodologies used in weighting citations still present limits in their underlying assumptions. This work takes an alternative approach to resolving the underlying problem: the proposal is to value citations by the impact of the citing articles, regardless of the length of their reference list. As well as conceptualizing a new indicator of impact, the work illustrates its application to the 2004–2012 Italian scientific production indexed in the WoS. The proposed impact indicator is highly correlated to the traditional citation count, however the shifts observed between the two measures are frequent and the number of outliers not negligible. Moreover, the new indicator shows greater “sensitivity” when used to identify the highly-cited papers.  相似文献

Abstract

This paper provides a methodology to study the characteristics of the research output from a university department. The faculty publications and their cited references over a 10-year period were used as the basis for this study to identify their publishing patterns and the types of material they are publishing; a core set of journals and other resources they are publishing in and citing over this period; the characteristics of the journals in which they publish and cite; the degree of openness of their publications and their citation advantage; and the age of resources that are referenced.  相似文献

中文医学学术期刊发表英文文章的实践与思考   总被引：1，自引：0，他引：1  
王丽  李欣欣  刘莉 《编辑学报》2005,17(4):284-286
中文医学学术期刊发表英文文章的现象较为普遍.通过对发表在<吉林大学学报(医学版)>上的112篇英文文章的发表时间、栏目、作者分布及被引用情况和其他3种较权威医学学术期刊发表的英文文章的数量及被引用情况进行分析,发现中文期刊发表的英文文章虽然具有较高的学术价值,但被国内期刊引用率明显低于同期发表的中文文章,SCI-E检索显示被引频次为0,认为中文医学学术期刊发表英文文章并没有起到扩大传播范围、促进期刊国际化的作用,而且浪费宝贵的信息资源.建议中文医学学术期刊不宜刊发英文文章,在国内应首选英文版期刊发表英文文章.  相似文献

In this paper, we conduct a comparative analysis to examine the characteristics and evolutionary trends of open access (OA) publications in natural and social sciences. We use data recorded by Science Citation Index Expanded, Social Sciences Citation Index, and Journal Citation Reports during 2001–2015 as the main source. We then comparatively analyse the characteristics of natural and social sciences in terms of historical evolution, main contributors, and distribution of OA journals and publications across different languages, disciplines, and impact factor quartiles. Our results suggest that both natural and social sciences experienced dramatic growth of OA journals since 2009, but the share of social science OA journals within journal impact factor quartile 1 is much lower than that of natural sciences. While natural and social sciences share some similarities in OA publishing activities, such as main countries of contribution, they differ greatly in dimensions such as OA ratio across specific disciplines, countries, and publishing languages. We acknowledge that OA publishing offers a level playing field for traditionally disadvantaged languages, countries, and scientific disciplines, but meanwhile, the advancement of high‐quality OA publishing needs more targeted and sophisticated approaches to tackle differences in natural and social sciences.  相似文献

学术论著应杜绝无效引用   总被引：4，自引：1，他引：3  
陶范 《编辑学报》2007,19(3):173-175
学术论著中的一些过度标引、不相关引用、错误引用以及引用的信息滞后是一种无效引用,它影响论著的简洁表达,损害论证力度,浪费出版资源,影响引文计量的真实性.为杜绝无效引用,应破除对参考文献的认识误区,遵循必要性、准确性、新颖性的引用原则,重视作者的养成教育,帮助提高其论文写作水平,编辑则需严格核查把关.  相似文献

期刊学术影响力、期刊对稿件的录用标准和期刊载文的学术影响力三者之间存在同向加强的机制,来自较高影响力期刊的引用具有较高的评价意义。作者的择刊引用和择刊发表使得较低学术影响力的期刊较少被较高影响力期刊引用。因而,可以通过同时考察构成期刊引证形象的施引期刊的学术影响力及其施引频次来评价被引期刊的学术影响力。以综合性期刊Nature和Science 2010年的引证形象为例,将期刊影响因子作为学术影响力的初评结果,提出了以施引频次对施引期刊影响因子加权的计算方法,以期通过量化的引证形象实现对期刊的评价。  相似文献

In 2008, the type of document “proceedings paper” (PP) was assigned in the WoS database to journal articles which were initially presented at a conference and later adapted for publication in a journal. Since the use of two different labels (“article” and “proceedings paper”) might lead to infer differences in their relevance and/or quality, this paper presents a comparative study of standard journal articles and PP in journals to explore potential differences between them. The study focuses on the Library and Information Science field in the Web of Science database and covers the 1990–2008 period. PP approximately account for 9% of the total number of articles in this field, two-thirds of which are published in monographic issues devoted to conferences, which tend to be concentrated in specific journals. Proceedings papers emerge as an heterogeneous set comprising PP in ordinary issues, similar to standard articles in structure and impact of research; and PP in monographic issues, which seem to be less comprehensive and tend to receive less citations. Faster publication of PP in monographic than in ordinary issues may conceal differences in the review process undergone by either type of paper. The main implications of these results for authors, bibliometricians, journal editors and research evaluators are pointed out.  相似文献

At a top psychology journal, Psychological Science (PS), submissions peak during the summer months. We tested whether this seasonal submission bias decreases the likelihood of a paper being accepted in that period. Month of submission data was obtained for all 575 publications in PS for the period 2003–2006. Whereas submissions to PS were higher in the summer, there was no evidence that most accepted publications were originally submitted in the summer. Thus, contributors submit to PS when the likelihood of acceptance is the lowest – creating their own entrance barrier. A similar seasonal pattern was not identified for Personality and Social Psychology Bulletin, another top psychology journal. Using the Web of Knowledge database, we further assessed whether overcoming the seasonal entrance barrier influences the number of citations a paper receives in subsequent years. We discuss the possibility that the different rejections policies in the two journals, employing desk rejections or not, may explain this discrepancy, and explore a range of alternative hypotheses.  相似文献
