    2009-01-01

    Methods developed for mapping the journal structures contained in aggregated journal-journal citations in the Science Citation Index are applied to the Chinese Science Citation Database of the Chinese Academy of Sciences. This database covers 991 journals, of which only 37 had originally English titles. Using factor-analytical and graph-analytical techniques we show that this data is dually structured. The main structure is the intellectual organization of the journals in journal groups (as in the international SCI), but the university-based journals provide an institutional layer that orients this structure towards practical ends (e.g., agriculture). The Chinese Science Citation Database exhibits the characteristics of Mode 2 in the production of scientific knowledge more than its western counterparts. The contexts of application lead to correlation (interfactorial complexity) among the components.

    In comparing reference unification to reference linking,the authors found that reference linking yield similar result as that of reference unification.An investigative study was conducted by these authors at Chinese Science Citation Database(CSCD)of National Science Library(NSL)of the ChineseAcademy of Sciences(CAS),it was found that there were three inhibiting elements in invoking a reference unification solution and the same is true for a reference linking solution.Firstly,it was difficult to define a minimum set of data elements for matching.Secondly,it had a problem of data inaccuracy and/or data incompleteness.Thirdly,it was hard to determine an appropriate linking result that produced the desired document for the user.Thus these authors suggest that getting Digital Object Identifier(DOI)for each journal article is a good way to bring about reference unification and also to improve metadata quality simultaneously at the same time.Therefore,DOI has a pivotal role to play in terms of bringing about reference unification and/or a reference linking.

  5. Citation analysis of faculty publication: beyond Science Citation Index and Social Science Citation Index.

    1995-10-01

    When evaluated for promotion or tenure, faculty members are increasingly judged more on the quality than on the quantity of their scholarly publications. As a result, they want help from librarians in locating all citations to their published works for documentation in their curriculum vitae. Citation analysis using Science Citation Index and Social Science Citation Index provides a logical starting point in measuring quality, but the limitations of these sources leave a void in coverage of citations to an author's work. This article discusses alternative and additional methods of locating citations to published works.

  6. Comparison of journal self-citation rates between some Chinese and non-Chinese international journals.

    Full Text Available BACKGROUND: The past 3 decades have witnessed a boost in science development in China; in parallel, more and more Chinese scientific journals are indexed by the Journal Citation Reports issued by Thomson Reuters (SCI. Evaluation of the performance of these Chinese SCI journals is necessary and helpful to improve their quality. This study aimed to evaluate these journals by calculating various journal self-citation rates, which are important parameters influencing a journal impact factor. METHODOLOGY/PRINCIPAL FINDINGS: We defined three journal self-citation rates, and studied these rates for 99 Chinese scientific journals, almost exhausting all Chinese SCI journals currently available. Likewise, we selected 99 non-Chinese international (abbreviated as 'world' journals, with each being in the same JCR subject category and having similar impact factors as their Chinese counterparts. Generally, Chinese journals tended to be higher in all the three self-citation rates than world journal counterparts. Particularly, a few Chinese scientific journals had much higher self-citation rates. CONCLUSIONS/SIGNIFICANCE: Our results show that generally Chinese scientific journals have higher self-citation rates than those of world journals. Consequently, Chinese scientific journals tend to have lower visibility and are more isolated in the relevant fields. Considering the fact that sciences are rapidly developing in China and so are Chinese scientific journals, we expect that the differences of journal self-citation rates between Chinese and world scientific journals will gradually disappear in the future. Some suggestions to solve the problems are presented.

    2009-01-01

    The journal structure in the China Scientific and Technical Papers and Citations Database (CSTPCD) is analysed from three perspectives: the database level, the specialty level and the institutional level (i.e., university journals versus journals issued by the Chinese Academy of Sciences). The results are compared with those for (Chinese) journals included in the Science Citation Index. The frequency of journal-journal citation relations in the CSTPCD is an order of magnitude lower than in the SCI. Chinese journals, especially high-quality journals, prefer to cite international journals rather than domestic ones. However, Chinese journals do not get an equivalent reception from their international counterparts. The international visibility of Chinese journals is low, but varies among fields of science. Journals of the Chinese Academy of Sciences (CAS) have a better reception in the international scientific community than university journals.

    2013-06-01

    Full Text Available To investigate the conditions of citation errors in different graduate programs, this study analyzed a total of 3,564 references cited in 125 master’s theses, endorsed respectively by the Departments of Information and Library Science (DILS as well as Department of Computer Science and Information Engineering (CSIE of Tamkang University in 2007 and 2011. The analyses focused on citation error rates, citation errors associated with different reference types, and the types of citation errors, i.e., numeric errors, textual errors, or both. The overall citation error rate within the sample theses was 22.8% (21% and 24.4% for the academic years of 2007 and 2011, respectively. Error rate for DILS was 20.1% and 24.3% for CSIE. Citation errors occurred mostly in references to books, followed by conference papers and theses. Citation error rates for each individual thesis ranged from 4% to 81.3%. The study results showed that citation instruction in graduate programs is highly needed to promote better citation behavior. The use of reference management tools combined with citation instruction via research methods and library instruction courses may effectively reduce the occurrence of citation errors.

    From a comparison of 1000+ references to 20 papers in four fields of astronomy (solar, stellar, nebular, galaxy), we found that the citation counts in Science Citation Index (SCI) and Astrophysics Data System (ADS) agree for 85% of the citations. ADS gives 15% more citation counts than SCI. SCI has more citations among physics and chemistry journals, while ADS includes more from conferences. Each one misses less than 1% of the citations.

  17. [Neutralizing science citation index as an academic evaluation system].

    Science.gov (United States)

    Liu, Xiu-Hua; Tang, Chao-Shu

    2009-01-01

    Research papers are published in thousands of scientific journals every year in the world. The quality of these papers has to be evaluated to determine their accuracy and contribution to their research fields. Science citation index (SCI) is a citation-based metric used to rank scientific journals. The importation of SCI from abroad contributed much both to encourage Chinese scientific community to collaborate with scientists all over the world, and the development of science and technology at home. However, there have been numerous criticisms over the years of the misuse of SCI, especially impact factor, as a measure of the quality of individual research papers. This review article analyzes the history and current situation of using SCI to evaluate scientific papers, discusses how to objectively consider SCI and the other new practices to evaluate research papers. It is also suggested in the present article that the impact of domestic scientific journals on the world should be improved, and that more attention should be paid to the quality of the research papers to improve the academic evaluation system and the development of science and technology in our country.

  18. Data Identifiers and Citations Enable Reproducible Science

    Tilmes, C.

    2011-12-01

    Modern science often involves data processing with tremendous volumes of data. Keeping track of that data has been a growing challenge for data center. Researchers who access and use that data don't always reference and cite their data sources adequately for consumers of their research to follow their methodology or reproduce their analyses or experiments. Recent research has led to recommendations for good identifiers and citations that can help address this problem. This paper will describe some of the best practices in data identifiers, reference and citation. Using a simplified example scenario based on a long term remote sensing satellite mission, it will explore issues in identifying dynamic data sets and the importance of good data citations for reproducibility. It will describe the difference between granule and collection level identifiers, using UUIDs and DOIs to illustrate some recommendations for developing identifiers and assigning them during data processing. As data processors create data products, the provenance of the input products and precise steps that led to their creation are recorded and published for users of the data to see. As researchers access the data from an archive, they can use the provenance to help understand the genesis of the data, which could have effects on their usage of the data. By citing the data on publishing their research, others can retrieve the precise data used in their research and reproduce the analyses and experiments to confirm the results. Describing the experiment to a sufficient extent to reproduce the research enforces a formal approach that lends credibility to the results, and ultimately, to the policies of decision makers depending on that research.

  6. A comparative study on communication structures of Chinese journals in the social sciences

    CERN Document Server

    Zhou, Ping; Leydesdorff, Loet

    2010-01-01

    We argue that the communication structures in the Chinese social sciences have not yet been sufficiently reformed. Citation patterns among Chinese domestic journals in three subject areas -- political science and marxism, library and information science, and economics -- are compared with their counterparts internationally. Like their colleagues in the natural and life sciences, Chinese scholars in the social sciences provide fewer references to journal publications than their international counterparts; like their international colleagues, social scientists provide fewer references than natural sciences. The resulting citation networks, therefore, are sparse. Nevertheless, the citation structures clearly suggest that the Chinese social sciences are far less specialized in terms of disciplinary delineations than their international counterparts. Marxism studies are more established than political science in China. In terms of the impact of the Chinese political system on academic fields, disciplines closely r...

  8. Invoking Thomas Kuhn: What Citation Analysis Reveals about Science Education

    Science.gov (United States)

    Loving, Cathleen C.; Cobern, William W.

    This paper analyzes how Thomas Kuhn's writings are used by others, especially science education researchers. Previous research in citation analysis is used to frame questions related to who cites Kuhn, in what manner and why. Research questions first focus on the variety of disciplines invoking Kuhn and to what extent Structure of Scientific Revolutions (SSR) is cited. The Web of Science database provides material from 1982 for this analysis. The science education literature is analyzed using back issues from 1985 of the Journal of Research in Science Teaching and Science Education. An article analysis reveals trends in terms of what Kuhnian ideas are most frequently invoked. Results indicate a wide array of disciplines from beekeeping to law cite Kuhn - especially generic citations to SSR. The science education journal analysis reveals pervasive use of the term paradigm, although use is quite varied. The two areas of research in science education most impacted by Kuhn appear to be conceptual change theory and constructivist epistemologies. Additional uses of Kuhn are discussed. The degree to which Kuhn is invoked in ways supporting the theoretical framework of citation analysis, whether his work is misappropriated, and the impact of Kuhn are discussed.

    2000-01-01

    The Institute for Science Information (ISI) has generated two lists of citation information for astronomers that are uniquely restricted both as to the years surveyed for the cited papers, and the years surveyed for the citing papers. The main list gives citation data for 62,813 physicists and astronomers whose journal papers were cited 100 times or more from 1981.0 to 1997.5 by papers published during the same time interval. The second list gives the 200 most-cited papers/year published in refereed astronomical journals from 1981-1996, as cited in papers in those same journals from 1981.0-1998.0. Astronomer names were selected from various sources. From this work an Astronomy Citation Database (ACD) has been constructed, containing citation data for 6331+ astronomers, plus additional data for 173 astronomers and the top-10 cited papers published 1981-1996. Various problems, both substantial and subtle, of producing a reasonably fair citation database are detailed. Chief among these are whether to assign eith...

  19. Citation Counting, Citation Ranking, and h-Index of Human-Computer Interaction Researchers: A Comparison between Scopus and Web of Science

    CERN Document Server

    Meho, Lokman I

    2008-01-01

    This study examines the differences between Scopus and Web of Science in the citation counting, citation ranking, and h-index of 22 top human-computer interaction (HCI) researchers from EQUATOR--a large British Interdisciplinary Research Collaboration project. Results indicate that Scopus provides significantly more coverage of HCI literature than Web of Science, primarily due to coverage of relevant ACM and IEEE peer-reviewed conference proceedings. No significant differences exist between the two databases if citations in journals only are compared. Although broader coverage of the literature does not significantly alter the relative citation ranking of individual researchers, Scopus helps distinguish between the researchers in a more nuanced fashion than Web of Science in both citation counting and h-index. Scopus also generates significantly different maps of citation networks of individual scholars than those generated by Web of Science. The study also presents a comparison of h-index scores based on Goo...

    Who today are the most highly cited psychologists listed in the Web of Science? This paper reports answers to this question by using the Science Citation Index Expanded to find out. This index covers over 280,350 documents in the Psychology category of the Web of Science from 1900 to 2013 and lists the most highly cited papers published between 1927 and 2012. For example, in 2013, an article published by Jacob Cohen in 1992 obtained (1) the highest ranking with 1,068 citations, (2) the highest for total citations per year, and (3) was ranked 3rd for the total number of citations since publication by 2013. New technology thus provides a seismic shift in the ways that we can obtain and analyse data like these. Indeed, the results for the top 10 articles indicate that practical and methodological papers now receive more citations than the more theoretical papers usually found in earlier surveys.

    Citations to previous literature are extensively used to measure the quality and diffusion of knowledge. However, we know little about the different ways in which a study can be cited; in particular, are papers cited to point out their merits or their flaws? We elaborated a methodology to characterize “negative” citations using bibliometric data and natural language processing. We found that negative citations concerned higher-quality papers, were focused on a study’s findings rather than theories or methods, and originated from scholars who were closer to the authors of the focal paper in terms of discipline and social distance, but not geographically. Receiving a negative citation was also associated with a slightly faster decline in citations to the paper in the long run. PMID:26504239

    To determine the features of papers, authors, and citation of eleven journals in tropical medicine indexed by Science Citation Index Expanded, the database of the Institute for Scientific Information, we analyzed original articles, editorials, reviews, corrections, letters, biographies, and news published in these journals. The results show that these journals covered 107 countries or regions on six continents. The average number of reference was 23.05, with 87.89% of the references from periodicals. The Price Index was 31.43% and the self-citing rate was 7.02%. The references in the first 20 journals ranked by the amount of citation accounted for 36.71% of the total citations. Brazil, United States, India, and England are more advanced in tropical medicine research. The conclusion is that these journals covered most research done in these countries or regions. Most researches were done by cooperation of the researchers, but many of the publications used outdated articles and should include newer information.

    A large number of theoretical and empirical studies on citation behavior have been conducted internationally.Although some theoretical studies on such topic have been carried out in China,few studies have focused specifically on this area from an empirical perspective,resulting in the lack of literature on the findings of actual surveys.To address this challenge,we conducted two questionnaire surveys to understand the motivations of the researchers on citation.One survey covers the authors who published articles in Chinese Journal of Scientific and Technical Periodicals,while the other targets the most productive and most cited Chinese authors in library and information science.The results show that citation behavior is not only motivated by rational factors,but also by other social factors.

    Full Text Available Based on the time of journal article first-citation appearance, this study analyzed the citation speeds of Open Access (OA journals within Library and Information Science (LIS field indexed in Scopus and WoS database. Articles published between 2010 and 2014 by a total of 8 Full-OA journals and 13 Hybrid-OA journals indexed by 2010-2013 edition of JCR were collected and analyzed in June 2015. Results showed that there were 639 articles being cited in Scopus and the average firstcitation speed was 1.17 year. On the other hand, there were 434 articles being cited in WoS with a slightly higher first-time citation rate of 1.37 year. Most of the articles studied were cited for the first time in the same year or the year after of its publication. There were some articles being cited even before its official publication. Within the Hybrid-OA journals, articles belong to the OA mechanism did have shorter speed citation time than non-OA ones. This study suggested that further studies could adopt the concept of Altmetrics to investigate the first-usage speeds through the formal and informal communication channels.

    We used bibliometric analysis methodology in the expanded Science Citation Index to identify highly-cited electrocardiogram (ECG)-related articles with total citations (TC2012) exceeding 100 from the publication year to 2012. Web of Science search tools were used to identify the highly-cited articles. The aspects analyzed for highly cited publications included effect of time on citation analysis, journals and Web of Science categories, number of authors per publication, originating institutions and countries, total citation and total citation per year life cycles of articles (C2012) and research hotspots. Results showed that a total of 467 electrocardiogram-related publications were regarded as the highly-cited publications. TC2012 ranged from 101 to 2879, with 215 as the average number of citations. No highly-cited publications have emerged yet during the first two years of the present 2010 Decade. All 11 countries and institutions originating highly-cited ECG-related publications were developed countries, USA in 9 of them. Four subject categories were identified as hotspots by total citations TC2012 and C2012: atrial fibrillation, long QT syndrome, angina and myocardial infarction, and risk factor analysis and health evaluation.

    The book is written paralelly in Serbian and English. The presence of works of Serbian astronomers and works in astronomical journals published by other Serbian scientists, in Science Citation Index within the period from 1945 up to the end of 2000, has been analyzed. Also is presented the list of 38 papers which had some influence on the development of astronomy in the twentieth century. A review of the development of astronomy in Serbia in the last century is given as well. Particular attention is payed to the Astronomical Observatory, the principal astronomical institution in Serbia, where it is one of the oldest scientific organizations and the only autonomous astronomical institute. Its past development forms an important part of the history of science and culture in these regions. In the book is also considered and the history of the university teaching of astronomy in Serbia after the second world war. First of all the development of the Chair of Astronomy at the Faculty of Mathematics in Belgrade, but also the teaching of astronomy at University in Novi Sad, Ni and Kragujevac is discussed. In addition to professional Astronomy, well developed in Serbia is also the amateur Astronomy. In the review is first of all included the largest and the oldest organization of amateur-astronomers in Serbia, founded in 1934. Besides, here are the Astronomical Society "Novi Sad", ADNOS and Research Station "Petnica". In Valjevo, within the framework of the Society of researchers "Vladimir Mandic - Manda", there is active also the Astronomical Group. In Kragujevac, on the roof of the Institute of Physics of the Faculty of Sciences, there is the "Belerofont" Observatory. In Ni, at the close of the sixties and the start of the seventies, there was operating a branch of the Astronomical Society "Rudjer Bokovic", while at the Faculty of Philosophy there existed in the period 1976-1980 the "Astro-Geophysical Society". In the year 1996 there was founded Astronomical Society

    Full Text Available   The present study investigate the correlation between journal citations with impact factor in the humanities scientific journals published for the 2001-2007 period based on the Persian journal citation reports generated by Islamic Science Citation (ISC database. Citation analysis method was used. Findings demonstrated that there is a significant link between impact factor and journal self-citation (r=0.606, s =0.0000. In other words, journals with low impact factors have fewer self-citations, i.e. self-citation has a positive impact on the journal impact factor. There is a negative correlation between impact factor and number of articles in humanities in the period studied. The impact factor does not increase with increase in the number of articles. There is significant correlation between the number of article published and number of self-citation. The higher the number of articles, the higher would be the number of self-citation in the journal. Findings indicated that the rate of journal self-citation in humanities had been downward for the period studied. When screening journals for self-citations, 108 journals had their ranks reduced while 204 journals had their ranking increased. The ranking in 32 journals remained unchanged.

    Full Text Available This article uses bibliometric analysis to study the evaluation of journals and researchers in the field of library and information science in Taiwan. For journal evaluation, the results show no statistically significant difference between the rankings of the citations cited by top LIS journals and by THCI journals. This suggests that the citation numbers of top LIS journals can be used to evaluate all the LIS journals. The results also show that the relationship between the rankings of JCR LIS journals and the rankings of the JCR LIS journals cited by top LIS journals is not statistically significant.This indicates that the rankings of the JCR LIS journals can not totally show their impacts on Taiwan LIS journals. For researcher evaluation, the results reveal that the correlation between the rankings of researchers cited by top LIS journals and the number of the research projects of National Science Council (NSC conducted by the researchers is not significant. This suggests using citation analyses as the only method to evaluate LIS researchers should be viewed with more prudence with the results. [Article content in Chinese

    2012-01-01

    Modern information and communication technologies, especially the Internet, have diminished the role of spatial distances and territorial boundaries. This has enabled scientists for closer collaboration and internationalization. Nevertheless, geography remains an important factor affecting the dynamics of science. Hence, assessing the influence of spatial proximity between scientists is crucial to promote efficient collaboration strategies and, ultimately, to improve the quality of science. Here we present a systematic analysis of citation and collaboration streams between cities and countries. By assigning papers to the geographic locations of their authors' affiliations, we construct weighted networks of citations and collaborations. The citation flows as well as the collaboration strengths between cities decrease with the distance between them and follow gravity laws with exponents close to 1. Moreover, for a given number of authors, the diversity of affiliations increases the number of citations, especial...

    2015-01-01

    Scopus and Web of Science are the two major citation databases that collect and disseminate bibliometric statistics about research articles, journals, institutions, and individual authors. Liaison librarians are now regularly called upon to utilize these databases to assist faculty in finding citation activity on their published works for tenure and promotion, grant applications, and more. But questions about the accuracy, scope, and coverage of these tools deserve closer scrutiny. Discrepancies in citation capture led to a systematic study on how Scopus and Web of Science compared in a real-life situation encountered by liaisons: comparing three different disciplines at a medical school and nursing program. How many articles would each database retrieve for each faculty member using the author-searching tools provided? How many cited references for each faculty member would each tool generate? Results demonstrated troubling differences in publication and citation activity capture between Scopus and Web of Science. Implications for librarians are discussed.

  16. Science Citation Index data: Two additional reasons against its use for administrative purposes

    CERN Document Server

    Herndon, J M

    2007-01-01

    First, for decades the use of anonymity in reviews for science funding proposals and for evaluating manuscripts for publication has been gradually corrupting American science, encouraging and rewarding the dark elements of human nature. Unethical reviewers, secure and unaccountable through anonymity, all too often make untrue and/or pejorative statements to eliminate their professional competitors. Survival in this corrupt environment has led to a consensus-only mentality. Consequently, important scientific contradictions, if they can be published at all, are selectively ignored in many instances out of fear of anonymous retaliation. Science Citation Index data in such a corrupt environment may be of little administrative value, except for possible use in documenting scientific fraud. Second, as knowledge of the administrative use of Science Citation Index data spreads, scientists will adapt and will shift to research on popular subjects to elicit greater numbers of citations, rather than to take the paths le...

    Full Text Available Abstract Articles published in English language journals with citations of non-English peer reviewed materials are not very common today. However, as epidemiologists are becoming more aware of data and information being readily available and accessible in the non-English literature, the question of whether non-English materials can be cited in English language journals and if so, how should they be cited, has become an increasingly important issue. Bringing together personal insights from the author's familiarity with both the English and Chinese language epidemiological literature and results from a survey on the use of citations of non-English peer reviewed materials across a sample of epidemiology and public health journals, this commentary discusses the different ways authors cite non-English articles in different English language journals and the different methods used by journals to handle non-Latin scripts (e.g. transliteration. This commentary will be useful to both epidemiologists and editors alike.

    2005-10-01

    In an increasingly "publish or perish" clinical and academic environment, all clinicians and clinician-scientists involved in research must have a firm understanding of the measures commonly used to assess the quality of scientific journals and, by default, those extended to grade individual articles and authors. The publication of research is a vital part of clinical and experimental research, and citation analyses of research publications have increasingly been adopted as a means of assessing the apparent quality of journals and the research published therein. In the first of a series of articles for those embarking on ophthalmic and vision science research, this paper discusses the key features of citation analysis, concentrating on the 2004 Journal Citation Report figures for the field of ophthalmology that include 42 ophthalmology, vision science, physiological optics, and optometry journals. The Institute for Scientific Information (ISI) calculates a number of parameters including citation counts, Journal Impact Factor (JIF), Immediacy Index, and cited/citing half-life. This article discusses the methods of calculation and possible uses along with current controversies and potential abuses. The JIF and its relevance, potential bias, and limitations are discussed in depth as it has become the most widely used analysis of journal quality. The possible alternatives to ISI citation analysis are presented, and we conclude that citation analysis can be considered a reasonable measure of journal research quality only if used correctly.

    Can change in citation patterns among journals be used as an indicator of structural change in the organization of the sciences? Aggregated journal-journal citations for 1999 are compared with similar data in the Journal Citation Reports 1998 of the Science Citation Index. In addition to indicating local change, probabilistic entropy measures enable us to analyze changes in distributions at different levels of aggregation. The results of various statistics are discussed and compared by elaborating the journal-journal mappings. The relevance of this indicator for science and technology policies is further specified.

    Citations to scholarly items are building bricks for multidisciplinary science communication. Citation analyses are currently influencing individual career advancement and ranking of academic and research institutions worldwide. This article overviews the involvement of scientific authors, reviewers, editors, publishers, indexers, and learned associations in the citing and referencing to preserve the integrity of science communication. Authors are responsible for thorough bibliographic searches to select relevant references for their articles, comprehend main points, and cite them in an ethical way. Reviewers and editors may perform additional searches and recommend missing essential references. Publishers, in turn, are in a position to instruct their authors over the citations and references, provide tools for validation of references, and open access to bibliographies. Publicly available reference lists bear important information about the novelty and relatedness of the scholarly items with the published literature. Few editorial associations have dealt with the issue of citations and properly managed references. As a prime example, the International Committee of Medical Journal Editors (ICMJE) issued in December 2014 an updated set of recommendations on the need for citing primary literature and avoiding unethical references, which are applicable to the global scientific community. With the exponential growth of literature and related references, it is critically important to define functions of all stakeholders of science communication in curbing the issue of irrational and unethical citations and thereby improve the quality and indexability of scholarly journals.

    2012-08-01

    The 126 most frequently cited articles published in the adsorption field between 1900 and 2011 were identified and characterized using the Science Citation Index (Expanded). The data analyzed cover a range of publication years, journals, Web of Science categories, authors, institutions, countries/territories, life citation cycle curves, and characteristics of frequently cited articles. The 126 most-frequently-cited articles were each cited an average of 1014 times, ranging from 502 to 9922 citations per article from 1918 to 2006; 80% of these articles were published after 1970. Fifty-five journals were represented, led by the Journal of the American Chemical Society, and followed by Science and Nature. Three categories out of the 35 Web of Science categories constituted 60% of the citations. The three categories were: physical chemistry, multidisciplinary chemistry, and multidisciplinary sciences. Thirteen of the authors contributed three or more articles. Harvard University, the Massachusetts Institute of Technology, and the University of Washington led the list of 107 institutions, while the United States led the list of 17 countries/territories, comprising more than half of the articles. Collaboration among the top authors was a frequent occurrence, while inter-institutional collaboration and national collaboration was not obvious among the topmost articles. Moreover, the citation patterns as a function of time varied widely among the topmost articles. As evidenced by citation life cycles, the well known BET and Langmuir isotherms have received considerable attention during the study period, and will probably continue to be popular in the adsorption field. Some emerging hotspots are likely to receive particular attention in the near future; these include the new family of "M41S" materials, pseudo-second-order kinetic models, and the nudged elastic band method.

  4. Publication boost in Web of Science journals and its effect on citation distributions

    CERN Document Server

    Šubelj, Lovro

    2016-01-01

    In this paper we show that the dramatic increase in the number of research articles indexed in the Web of Science database impacts the commonly observed distributions of citations within these articles. First, we document that the growing number of physics articles in recent years is due to existing journals publishing more and more papers rather than more new journals coming into being as it happens in computer science. And second, even though the references from the more recent papers generally cover a longer time span, the newer papers are cited more frequently than the older ones if the uneven paper growth is not corrected for. Nevertheless, despite this change in the distribution of citations, the citation behavior of scientists does not seem to have changed.

    Full Text Available Objective  Based on the status of citation of articles published in Medical Journal of Chinese PLA, to analyze the academic value of the Medical Journal of Chinese PLA, and provide information for assessing dominant medical disciplines and major groups of contributors, and for appraisal of outstanding articles. Methods  The journal citation data were obtained from the China Academic Journal Network Publishing Database(CAJD. The individual citation data of the scientific articles published in Medical Journal of Chinese PLAfrom 2000 to 2009 were retrieved from CAJD. Articles with citation frequency equal to or higher than 30 times were collected for analysis, and they were defined as highly cited articles. Based on these highly cited articles, we analyzed the authors' institutions, research discipline distribution and types of research projects. We also made a vertical comparison of average citation frequency in every year. Results  The total number of articles with citation frequency equal to or higher than 30 times was 50. The yearly average citation frequency increased year by year, from 0.05 times in the year 2000 to 4.46 times in the year 2009. Distribution of authors and institutions was as follows: authors of 11 articles were working in General Hospital of Chinese PLA and 302 Hospital of PLA respectively, authors of 6 articles were working in the Second Military Medical University, 5 in the First Military Medical University and Third Military Medical University, respectively, 4 in 304 Hospital of Chinese PLA. The articles from these 6 institutions accounted for 84% of all highly cited articles. Research fields distribution were as follows: 12 articles in infectious diseases, 7 in field surgery, 6 in trauma and burns.

    The Korean Journal of Urology began to be published exclusively in English in 2010 and is indexed in PubMed Central/PubMed. This study analyzed a variety of citation indicators of the Korean Journal of Urology before and after 2010 to clarify the present position of the journal among the urology category journals. The impact factor, SCImago Journal Rank (SJR), impact index, Z-impact factor (ZIF, impact factor excluding self-citation), and Hirsch Index (H-index) were referenced or calculated from Web of Science, Scopus, SCImago Journal & Country Ranking, Korean Medical Citation Index (KoMCI), KoreaMed Synapse, and Google Scholar. Both the impact factor and the total citations rose rapidly beginning in 2011. The 2012 impact factor corresponded to the upper 84.9% in the nephrology-urology category, whereas the 2011 SJR was in the upper 58.5%. The ZIF in KoMCI was one fifth of the impact factor because there are only two other urology journals in KoMCI. Up to 2009, more than half of the citations in the Web of Science were from Korean researchers, but from 2010 to 2012, more than 85% of the citations were from international researchers. The H-indexes from Web of Science, Scopus, KoMCI, KoreaMed Synapse, and Google Scholar were 8, 10, 12, 9, and 18, respectively. The strategy of the language change in 2010 was successful from the perspective of citation indicators. The values of the citation indicators will continue to increase rapidly and consistently as the research achievement of authors of the Korean Journal of Urology increases.

  15. Narrative Style Influences Citation Frequency in Climate Change Science.

    Science.gov (United States)

    Hillier, Ann; Kelly, Ryan P; Klinger, Terrie

    2016-01-01

    Peer-reviewed publications focusing on climate change are growing exponentially with the consequence that the uptake and influence of individual papers varies greatly. Here, we derive metrics of narrativity from psychology and literary theory, and use these metrics to test the hypothesis that more narrative climate change writing is more likely to be influential, using citation frequency as a proxy for influence. From a sample of 732 scientific abstracts drawn from the climate change literature, we find that articles with more narrative abstracts are cited more often. This effect is closely associated with journal identity: higher-impact journals tend to feature more narrative articles, and these articles tend to be cited more often. These results suggest that writing in a more narrative style increases the uptake and influence of articles in climate literature, and perhaps in scientific literature more broadly.

  16. Blog Citations as Indicators of the Societal Impact of Research : Content Analysis of Social Sciences Blogs

    Full Text Available This article analyzes motivations behind social sciences blog posts citing journal articles in order to find out whether blog citations are good indicators for the societal impact or benefits of research. A random sample of 300 social sciences blog posts (out of 1,233 blog posts from ResearchBlogging.org published between 01/01/2012 to 18/06/2014 were subjected to content analysis. The 300 blog posts had 472 references including 424 journal articles from 269 different journals. Sixty‐one (22.68% of all cited journals were from the social sciences and most of the journals with high frequency were highly cited general science journals such as PNAS and Science. Seventy‐five percent of all journals were referenced only once. The average age of articles cited at the time of citation was 5.8 years. Discussion and criticism were the two main categories of motivations. Overall, the study shows the potential of blog citations as an altmetric measure and as a proxy for assessing the research impact. A considerable number of citation motivations in blogs such as disputing a belief, suggesting policies, providing a solution to a problem, reacting to media, criticism and the like seemed to support gaining societal benefits. Societal benefits are considered as helping stimulate new approaches to social issues, or informing public debate and policymaking. Lower self‐citation (compared to some other altmetric measures such as tweets and the fact that blogging involves generating content (i.e. an intellectual process give them an advantage for altmetrics. However, limitations and contextual issues such as disciplinary differences and low uptake of altmetrics, in general, in scholarly communication should not be ignored when using blogs as a data source for altmetrics.

    The published articles and citation of the Chinese Journal of Parasitology and Parasitic Diseases in 2004-2005 were statistically analyzed. Among 312 papers published in the two years, original articles and experiment reports occupied 42.3% and 7.7% respectively. Authors were mainly from colleges/universities (61.5%) and institutions for disease control (28.5%). 51.9% of the articles received support by research funds/foundations. 82.3% were with reference citation mostly from periodicals, with 58.7% and 31.5% respectively from international and national (Chinese) journals. The average Price index was 44.9%. This Journal possesses a group of stable and qualified authors, covers substantial content with relatively broad citation, and is an important source of information in parasitological research.

  18. Evidence of pro-homosexual bias in social science: citation rates and research on lesbian parenting.

    2010-04-01

    Three refereed journal articles concerning lesbian family life were identified and compared for content and methodological quality. The articles shared the same authors, same academic institution of origin, the same samples, similar dates of publication, and even the same journals. However, one article reported evidence less supportive of lesbian parenting while two articles reported evidence more supportive of lesbian parenting. Citation rates for the articles were compared. The supportive reports have been cited 28 to 37 times since their publication compared to only two citations for the less supportive report, in spite of its possibly better methodological qualities. The citation rate differences were statistically significant. Implications for this possible evidence of pro-homosexual bias in the social sciences are discussed.

    2014-01-01

    Solomon Hsiang is representative of a new generation in the geosciences community, whose work spans several disciplines, drawing on methods and concepts from far outside the traditional physical science domain in order to make progress on difficult questions at the intersection of natural science, social science, and public policy. Broadly speaking, by examining how humanity has responded to climate variability and change in the distant and recent past, Sol's research elucidates the question of how humanity may respond to a changing climate in the future. Combining large, independent sets of social science, meteorological, and climatological data and analyzing them with tools more common in microeconomics than natural science, Sol, still at an early stage of his career, has made critical contributions to an incipient revolution in our understanding of the sensitivity and adaptability of humans and their social arrangements to climate variability and change. Such insights will greatly improve the information base from which effective public policy is developed.

    This paper explores the characteristics of maps of science generated from a relatively new type of citation: web citation. The web citation data were extracted from the Chinese Science Citation Database, then were used to analyze the structure of science by applying co-classification analysis, factor analysis and visualization. The result of factor analysis is different from other studies in which the main disciplines are extracted by factor analysis. The result of factor analysis in this research shows that science research in China is application-oriented and coincides with the current national conditions. The form of map of science generated from web citation data is centric. There are four obvious characteristics in maps based on web citation data compared with maps based on other types of data:computer science is the largest node in the network of web citation;computer science is also the central node;the relationship among disciplines is more direct and the interdisciplinarity is stronger in the network of web citation;the order of main disciplines in map of science based on web citation is in accord with other maps of science, and it shows that the hardness of science has negative relation with the number of web citation.%基于一类相对较新的引文形式---网络引文绘制科学知识图谱,探讨网络引文中科学结构的特点。网络引文数据来源于中国科学引文数据库。主要采用因子分析和共类分析方法。与其他研究中因子分析能够得出主干学科领域有所不同,基于网络引文数据所得的因子分析结果体现出学科间的相互关系与当前国情的契合性,以及国内科学研究的应用性特征。网络引文中的科学结构地图属于中心型科学知识图谱,它在四个方面与其他研究中的科学结构地图存在异同:计算机科学是网络引文网络中最大的节点,同时也是中心节点;网络引文网络中学科间的

    As web citation becomes an important component in references under the network environment that availability has received increasing attention. Choosing four core library science journals in China published between 2009 and 2013, this study takes an empirical analysis of their web citations (P-W web citation). The yearly as well as overall availability of web citations, the reasons for web citation’s unavailability, and the relations between web citations’ availability and corresponding webpage’s domain, format, language, type and URL depth are explored. The study argues that strengthening the archiving of online information resources, improving the maintenance of websites, and selecting online information sources prudently are effective measures to increase the availability of web citations.%网络环境下,网络引文已成为参考文献的重要组成部分,其可追溯性也日益受到关注。文章选取四种中国图书馆学核心期刊,对其2009至2013年间所刊载论文中网络引文(P-W型网络引文)的历年和总体可追溯情况、不可追溯的原因,以及网络引文的可追溯率与网站域名、网页格式、网页语种、页面类型与网址深度间的关系进行实证分析。认为强化网络信息资源的存档工作、加大网站的维护力度、审慎地选择网络信息源是提升网络引文可追溯率的有效举措。

    A well-designed and comprehensive citation index for the social sciences and humanities has many potential uses, but has yet to be realised. Significant parts of the scholarly production in these areas are not published in international journals, but in national scholarly journals, in book chapters...... or in monographs. The potential for covering these literatures more comprehensively can now be investigated empirically using a complete publication output data set from the higher education sector of an entire country (Norway). We find that while the international journals in the social sciences and humanities...... are promising for a more comprehensive coverage of the social sciences and humanities....

    Full Text Available The present study determines the co-authorship factor in the Iranian scientific output between 2000 and 2006 as reflected in the science, social science art and humanities citation indexes made available through the Web of Science database. Webometric indicators were used. The data were extracted in plain text from WOS, analyzed using HistCite software and counted in MS Office Excel program. Of the Total of 25320 documents indexed, 24480 documents were in Science Citation Index, 783 in Social Citation Index and 57 in Art and Humanities index. The findings indicated that co-authorship factor in the period studied had been on the rise. The highest participation rate belonged to the documents with two or three authors. General coauthorship factor was 0.59. The year 2006 had the highest coauthorship factor (0.62 while the year 2000 had the least (0.55. Bradford and Lotka laws were applied to the data sets. The Lotka’s Law only held true for the science citation index. The Bradford’s Law, however, held true for all indexes. In all citation indexes, the United States with 1865 documents (7.38 had the highest degree of coauthorship in Iranian scientific output.

    Despite of its small size, the Central American country of Costa Rica is internationally recognized as one of the world leaders in conservation and as the Central American leader in science. There have been no recent studies on the country's scientific production. The objective of this study was to analyze the Costa Rican scientific output as represented in the Science Citation Index Expanded. All documents with "Costa Rica" in the address field from 1981 to 2010 were included (total 6 801 publications). Articles (79%) were more frequent than other types of publication and were mostly in English (83%). Revista de Biología Tropical published the most articles (17%), followed by Toxicon and Turrialba (2.5%). The New England Journal of Medicine had the highest impact factor (53.484) with nine articles. Of 5 343 articles with known institutional address, 63%were internationally collaborative articles (most with the USA) with h index 91 and citation per publication 18. A total of 81% of all articles were inter-institutionally collaborative articles, led by the Universidad de Costa Rica. This reflects research and education agreements among these countries. Universidad de Costa Rica ranked top one in inter-institutionally collaborative articles, the rank of the total inter-institutionally collaborative articles, and the rank of first author articles and corresponding author articles. Studied subjects and journals in our sample are in agreement with dominant science fields and journals in Costa Rica. Articles with the highest citation were published in New England Journal of Medicine. The largest citation of medical articles reflects the general interest and wider readership of this subject. All corresponding and first authors of the high impact articles were not from Costa Rica. In conclusion, the scientific output of Costa Rican authors is strong in the areas related to conservation but the impact is higher for biomedical articles, and Costa Rican authors need to

    Citation metrics and h indices differ using different bibliometric databases. We compiled the number of publications, number of citations, h index and year since the first publication from 340 soil researchers from all over the world. On average, Google Scholar has the highest h index, number of publications and citations per researcher, and the Web of Science the lowest. The number of papers in Google Scholar is on average 2.3 times higher and the number of citations is 1.9 times higher compared to the data in the Web of Science. Scopus metrics are slightly higher than that of the Web of Science. The h index in Google Scholar is on average 1.4 times larger than Web of Science, and the h index in Scopus is on average 1.1 times larger than Web of Science. Over time, the metrics increase in all three databases but fastest in Google Scholar. The h index of an individual soil scientist is about 0.7 times the number of years since his/her first publication. There is a large difference between the number of citations, number of publications and the h index using the three databases. From this analysis it can be concluded that the choice of the database affects widely-used citation and evaluation metrics but that bibliometric transfer functions exist to relate the metrics from these three databases. We also investigated the relationship between journal's impact factor and Google Scholar's h5-index. The h5-index is a better measure of a journal's citation than the 2 or 5 year window impact factor.

    2013-02-01

    Full Text Available INTRODUCTION The observation that open access (OA articles receive more citations than subscription-based articles is known as the OA citation effect (OACE. Implicit in many OACE studies is the belief that authors are heavily invested in the number of citations their articles receive. This study seeks to determine what influence the OACE has on the decision-making process of tenure-track science faculty when they consider where to submit a manuscript for publication. METHODS Fifteen tenure-track faculty members in the Departments of Biology and Chemistry at the University of North Carolina at Chapel Hill participated in semi-structured interviews employing a variation of the critical incident tecnique. RESULTS Seven of the fifteen faculty members said they would consider making a future article freely-available based on the OACE. Due to dramatically different expectations with respect to the size of the OACE, however, only one of them is likely to seriously consider the OACE when deciding where to submit their next manuscript for publication. DISCUSSION Journal reputation and audience, and the quality of the editorial and review process are the most important factors in deciding where to submit a manuscript for publication. Once a subset of journals has satisfied these criteria, financial and access issues compete with the OACE in making a final decision. CONCLUSION In order to increase the number of OA materials, librarians should continue to emphasize depositing pre- and post-prints in disciplinary and institutional repositories and retaining the author rights prior to publication in order to make it possible to do so.

  5. The rate of growth in scientific publication and the decline in coverage provided by Science Citation Index.

    Larsen, Peder Olesen; von Ins, Markus

    2010-09-01

    The growth rate of scientific publication has been studied from 1907 to 2007 using available data from a number of literature databases, including Science Citation Index (SCI) and Social Sciences Citation Index (SSCI). Traditional scientific publishing, that is publication in peer-reviewed journals, is still increasing although there are big differences between fields. There are no indications that the growth rate has decreased in the last 50 years. At the same time publication using new channels, for example conference proceedings, open archives and home pages, is growing fast. The growth rate for SCI up to 2007 is smaller than for comparable databases. This means that SCI was covering a decreasing part of the traditional scientific literature. There are also clear indications that the coverage by SCI is especially low in some of the scientific areas with the highest growth rate, including computer science and engineering sciences. The role of conference proceedings, open access archives and publications published on the net is increasing, especially in scientific fields with high growth rates, but this has only partially been reflected in the databases. The new publication channels challenge the use of the big databases in measurements of scientific productivity or output and of the growth rate of science. Because of the declining coverage and this challenge it is problematic that SCI has been used and is used as the dominant source for science indicators based on publication and citation numbers. The limited data available for social sciences show that the growth rate in SSCI was remarkably low and indicate that the coverage by SSCI was declining over time. National Science Indicators from Thomson Reuters is based solely on SCI, SSCI and Arts and Humanities Citation Index (AHCI). Therefore the declining coverage of the citation databases problematizes the use of this source.

    There are often differences in a publication's citation count, depending on the database accessed. Here, aspects of citation counts for medical physics and biomedical engineering papers are studied using papers published in the journal Australasian physical and engineering sciences in medicine. Comparison is made between the Web of Science, Scopus, and Google Scholar. Papers are categorised into subject matter, and citation trends are examined. It is shown that review papers as a group tend to receive more citations on average; however the highest cited individual papers are more likely to be research papers.

    A bibliometric analysis was conducted to evaluate groundwater research from different perspectives in the period 1993-2012 based on the Science Citation Index-Expanded (SCIE) database. The bibliometric analysis summarizes output, categorical, geographical, and institutional patterns, as well as research hotspots in global groundwater studies. Groundwater research experienced notable growth in the past two decades. “Environmental sciences”, “water resources” and “multidisciplinary geosciences” were the three major subject categories. The Journal of Hydrology published the largest number of groundwater-related publications in the surveyed period. Major author clusters and research regions are located in the United States, Western Europe, Eastern and Southern Asia, and Eastern Australia. The United States was a leading contributor to global groundwater research with the largest number of independent and collaborative papers, its dominance affirmed by housing 12 of the top 20 most active institutions reporting groundwater-related research. The US Geological Survey, the Chinese Academy of Sciences, and the USDA Agricultural Research Service were the three institutions with the largest number of groundwater-related publications. A keywords analysis revealed that groundwater quality and contamination, effective research technologies, and treatment technologies for water-quality improvement were the main research areas in the study period. Several keywords such as “arsenic”, “climate change”, “fluoride”, “groundwater management”, “hydrogeochemistry”, “uncertainty”, “numerical modeling”, “seawater intrusion”, “adsorption”, “remote sensing”, “land use”, “USA”(as study site), and “water supply” received dramatically increased attention during the study period, possibly signaling future research trends.

    Chinese scientific output has increased dramatically in recent years, but its internal spatial structure has received scant attention. Estimated gravity models of intercity scientific coauthorships show that there are two types of spatial political bias in China, apart from the expected mass...... and distance effects. Intercity coauthorships involving Beijing are more common than Beijing's output volume and location would imply, and this Beijing bias is increasing over time. The second type of spatial political bias is greater intraprovincial collaboration than is accounted for by size and distance...

    2011-05-01

    This study was conceived to evaluate the global scientific output of climate change research over the past 18 years and to assess the characteristics of the research patterns, tendencies, and methods in the papers. Data were based on the online version of Science Citation Index Expanded from 1992 to 2009. Articles referring to climate change were assessed by distribution of source countries, source institutes, paper titles, author keywords, KeyWords Plus, abstracts, and the most cited articles in these years. By synthetic analysis of the four kinds of keywords, it was concluded that the items "temperature", "environment", "precipitation", "greenhouse gas", "risk", and "biodiversity" will be the foci of climate change research in the 21st century, while "model", "monitoring", and "remote sensing" will continue to be the leading research methods. A novel method, "phylogeography", may have a strong application potential in the near future.

Such funding currently involves valuation of the results of a scientific work by applying citation metrics methods, which are not acknowledged in Europe. Citation metrics in the USA, where it was created, lead to caricature forms of scientific products, composed of several pages of text and a great number of cited (quoted titles. Citation metrical-citation manic procedure can lead to the elimination of the domestic humanistic sciences and the implementation of third rate quoteres, who, along with hollow articles filled with mutually intertwined citations, fulfill requirements, unconsciously(? set by the authorized Ministry and University.

    To grasp the international developing tendency of acupuncture research and provide some references for promoting acupuncture and moxibustion internationalization process, the articles about acupuncture in Science Citation Index (SCI) periodicals in 2007 were retrieved by adopting the retrieval tactics on line in combination with database searching. Results indicate that 257 articles about acupuncture had been retrived from the SCI Web databases. These articles were published in 125 journals respectively, most of which were Euramerican journals. Among these journals, the impact factor of the Journal of the American Medical Association (JAMA), 25. 547, is the highest one. It is shown that the impact factors of the SCI periodicals, in which acupuncture articles embodied are increased, the quality of these articles are improved obviously and the types of the articles are various in 2007, but there is obvious difference in the results of these studies due to the difference of experimental methods, the subjects of these experiments and acupuncture manipulations. Therefore, standardization of many problems arising from the researches on acupuncture is extremely imminent.

    We analyze international co-authorship relations in the Social Science Citation Index 2011 using all citable items in the DVD-version of this index. Network statistics indicate four groups of nations: (i) an Asian-Pacific one to which all Anglo-Saxon nations (including the UK and Ireland) are attributed; (ii) a continental European one including also the Latin-American countries; (iii) the Scandinavian nations; and (iv) a community of African nations. Within the EU-28 (including Croatia), eleven of the EU-15 states have dominant positions. Collapsing the EU-28 into a single node leads to a bi-polar structure between the US and EU-28; China is part of the US-pole. We develop an information-theoretical test to distinguish whether international collaborations or domestic collaborations prevail; the results are mixed, but the international dimension is more important than the national one in the aggregated sets (this was found in both SSCI and SCI). In France, however, the national distribution is more important ...

    This study was conducted to explore a bibliometric approach to quantitatively assess current research trends in cisplatin-containing chemotherapy for small cell lung cancer (SCLC), using related literature in the Science Citation Index Expanded database from 1992 to 2011. Articles were analyzed by the scientific output and research performances of countries and institutions. The distribution of key words in the article title and author-selected keywords were used to evaluate research trends. It was observed that the number of articles devoted to cisplatin-containing chemotherapy for SCLC did not increase with time. The USA and Japan were the top two countries with the highest number of articles devoted to cisplatin-containing chemotherapy for SCLC. In both countries, the number of articles did not increase with time, and a decreasing trend was identified in the USA over the last 10 years. This study demonstrates trends in cisplatin-containing chemotherapy for SCLC. The clinical application of novel drugs is required for successful SCLC treatment.

    This study analyzed the publications of authors from Costa Rican institutions that were included in the Science Citation Index (SCI) during 1999-2001. Out of the 722 references detected, distributed in 328 journals, 90.7% corresponded to original research articles. The total productivity figures showed a moderately increasing trend, both in absolute and population-adjusted terms, in concordance with previous data recorded for the period 1980-1998. The contribution of Revista de Biología Tropical to these figures corresponded to 10.0%, 8.9%, and 19.1%, for the years 1999, 2000, and 2001, respectively. The subject distribution of articles followed a similar pattern to that described for 1980-1998, with a predominance of biomedical (33.3%) and biological (27.5%) sciences, followed by agronomical (15.5%) sciences, chemistry (13.6%), physics (5.0%), geological sciences (3.6%), and mathematics (1.5%). Citation analyses for individual publications (up to July 15, 2002) revealed that only 45.2% of the articles had been cited at least once. The ten most cited references were analyzed, varying from 26 to 114 citations. The average citation per article was 2.60, and the average number of authors per article was 2.92. In agreement with data from 1980-1998, the University of Costa Rica appeared as the institution with highest productivity of SCI publications during 1999-2001, with a contribution of 50.0%. The percentage of publications performed without the participation of foreign co-authors showed a change in its decreasing trend of 1980-1998, stabilizing near the range of 25-30% during the period 1999-2001.

    The Korean Journal of Internal Medicine (KJIM) is the international journal published in English by the Korean Association of Internal Medicine. To understand the position of the journal in three different databases, the citation indicators were elucidated. From databases such as Korean Medical Citation Index (KoMCI), Web of Science, and Scopus, citation indicators such as the impact factor, SCImago journal rank (SJR), or Hirsch Index were calculated according to the year and the results were drawn. The KJIM 2010 impact factor increased to 0.623 in Web of Science. That of year 2009 in KoMCI was a 0.149. The 2009 SJR in Scopus was 0.073, with a ranking of 27/72 (37.5%) in the category of internal medicine and 414/1,618 (25.6%) in the category of medicine, miscellaneous. The Hirsch Index from KoMCI, Web of Science and Scopus were 5, 14, and 16, respectively. The KJIM is now cited more by international researchers than Korean researchers, indicating that the content of the journal is now valued at the international level.

    The authors of this article analyzed the differences in output when searching MEDLINE direct and MEDLINE via citation management software, EndNote X1, EndNote Web, and RefWorks. Several searches were performed on Ovid MEDLINE and PubMed directly. These searches were compared against the same searches conducted in Ovid MEDLINE and PubMed using the search features in EndNote X1, EndNote Web, and RefWorks. Findings indicated that for in-depth research users, should search the databases directly rather than through the citation management software interface. The search results indicated it would be appropriate to search databases via citation management software for citation verification tasks and for cursory keyword searching.

    Full Text Available The aim of this paper is to describe and critically analyse the application of citation analysis in the collection evaluation in academic libraries, and to present the results of the study. The study, first of its kind in Croatia, was carried out in the information sciences collection at the Faculty of Humanities and Social Sciences in Osijek. Based on many studies from abroad done in the academic environment, the citation analysis, despite its disadvantages, proved to be a valid method for the collection of indicators of real use of (library information sources. The study analysed citation patterns, characteristics of information sources used by respondents and the accessibility of these sources in the academic library. Its aim was also to test the method of citation analysis in the context of library collection evaluation. The samples used in this study were papers published in 2010 by the students and teachers of the Department of Information Sciences in Osijek. The data analysis showed that while students preferred electronic information sources, teachers preferred print sources. Also, periodicals and monographs were top two information types used in the compilation of studied publications. However, students used undefined type of web resources such as presentations and commercial and educational websites to a great extent. As far as accessibility of sources used is concerned, the results show that library offers access to 60% of periodicals used and approximately 25% of monographs. In order to minimize the limitations of this quantitative method and to obtain valid and reliable indicators of citation patterns and use of (library information sources by students and teachers at the given Department, this study should be carried out longitudinally. It should also be complemented with a qualitative study (e.g. interview with teachers and students.

  11. Clusters and Maps of Science Journals Based on Bi-connected Graphs in the Journal Citation Reports

    2009-01-01

    The aggregated journal-journal citation matrix derived from the Journal Citation Reports 2001 can be decomposed into a unique subject classification by using the graph-analytical algorithm of bi-connected components. This technique was recently incorporated in software tools for social network analysis. The matrix can be assessed in terms of its decomposability using articulation points which indicate overlap between the components. The articulation points of this set did not exhibit a next-order network of 'general science' journals. However, the clusters differ in size and in terms of the internal density of their relations. A full classification of the journals is provided in an Appendix. The clusters can also be extracted and mapped for the visualization.

  14. "Smart Girls" versus "Sleeping Beauties" in the Sciences: The Identification of Instant and Delayed Recognition by Using the Citation Angle

    CERN Document Server

    Ye, Fred Y

    2016-01-01

    In recent years, a number of studies have introduced methods for identifying papers with delayed recognition (so called "sleeping beauties", SBs) or have presented single publications as cases of SBs. Most recently, Ke et al. (2015) proposed the so called "beauty coefficient" (denoted as B) to quantify how much a given paper can be considered as a paper with delayed recognition. In this study, the new term "smart girl" (SG) is suggested to differentiate instant credit or "flashes in the pan" from SBs. While SG and SB are qualitatively defined, the dynamic citation angle \\b{eta} is introduced in this study as a simple way for identifying SGs and SBs quantitatively - complementing the beauty coefficient B. The citation angles for all articles from 1980 (n=166870) in natural sciences are calculated for identifying SGs and SBs and their extent. We reveal that about 3% of the articles are typical SGs and about 0.1% typical SBs. The potential advantages of the citation angle approach are explained.

  15. Analysis of trends in publications and citations of papers on nuclear science and technology field in Korea: Focusing on the Scopus Data Base

    2015-10-15

    The data on the top 20 journals in the Science Citation Index(Expanded) for 10 years from 2005 to 2014 indicated the first and second positions for Korean papers were occupied by the Korean journals, which implied the need for globalization of target journals to publish Korean papers. Further study is required for comparative analysis of the factors impacting on the number of papers and citations, which is the criteria for quality evaluation of papers, in other area than the Nuclear Energy and Engineering to which this study was limited. As the media for research process and results, papers play an important role in the evaluation of research projects. While the traditional methods for evaluation of research results have been focused on quantity aspects, the implication of quality aspect is increasingly recognized. Most national labs have begun to shift from quantity to quality in their criteria for overall evaluation of research results. It is therefore desired to maximize the quality level of the research papers for which the trends in citation as quality indicator could be analyzed as well as the quantity aspect. This paper looks at the trends in the number of citation and papers as the indicators of quality and quantify, as drawn from Scopus Data Base. It also suggest top 5 Science Citation Index(Expanded) journals in terms of increase rate in both number of papers and citations. The purpose is to compare them with top 20 Science Citation Index(Expanded) journals in which Korea Atomic Energy Research researchers have published their papers in the past 10 years from 2005 to 2014 were submitted. This paper looked at the trends in the number of papers and citations as an indicator of quality of the research papers in the area of Nuclear Energy and Engineering which is in fact a limitation to the key subject area, not covering the whole nuclear science and technology.

    2012-06-01

    Full Text Available Background:Currently, share of the scientific output, citation per paper,and co-authorship for articles indexed in databases such as ISI Web of Science,are very important criteria for the evaluation and ranking of countries, researchers, institutes, articles, disciplines and journals in the world. Therefore,the main objectives of the study were to determine co-authorship, the average citation per paper and the most prolific Iranian university or institution in the field of immunology. Methods: For performing this scientometric study, we employed survey methods and citation analysis of the indexed papers in the ISI Web of Science from 1974 to 2010. Results: A total of 1775 articles by Iranian authors in the field of immunology had been indexed in the database for the aforesaid period. Most collaborations and co-authorship of Iranian authors was with their counterparts from the USA. The average citation per paper in the field was 6.26 per paper. Tehran University of Medical Sciences had the highest number of articles in the database. Conclusion: According to the results, Iranians collaborated with American peers more than any other nationality andthe average citation per paper in the field of immunology is higher than that of other fields in Iran but lower than the global average. Tehran University of Medical Sciences is the most prolific university in the field.

Besides offering clues about how to improve one's scientific impact, our citation analysis also sheds light on the state of the field of economic history....... Consistent with our expectations, we find that full professors, authors appointed at economics and history departments, and authors working in Anglo-Saxon and German countries are more likely to receive citations than other scholars. Long and co-authored articles are also a factor for citation success. We...... find similar patterns when assessing the same authors' citation success in economics journals. As a novel feature, we demonstrate that the diffusion of research — publication of working papers, as well as conference and workshop presentations — has a first-order positive impact on the citation rate....

  19. Scientific citations in Wikipedia

    Nielsen, Finn Aarup

    2007-01-01

    The Internet-based encyclopaedia Wikipedia has grown to become one of the most visited web-sites on the Internet. However, critics have questioned the quality of entries, and an empirical study has shown Wikipedia to contain errors in a 2005 sample of science entries. Biased coverage and lack of sources are among the "Wikipedia risks". The present work describes a simple assessment of these aspects by examining the outbound links from Wikipedia articles to articles in scientific journals with a comparison against journal statistics from Journal Citation Reports such as impact factors. The results show an increasing use of structured citation markup and good agreement with the citation pattern seen in the scientific literature though with a slight tendency to cite articles in high-impact journals such as Nature and Science. These results increase confidence in Wikipedia as an good information organizer for science in general.

    Full Text Available Objective – To determine whether three competing citation tracking services result in differing citation counts for a known set of articles, and to assess the extent of any differences.Design – Citation analysis, observational study.Setting – Three citation tracking databases: Google Scholar, Scopus and Web of Science. Subjects – Citations from eleven journals each from the disciplines of oncology and condensed matter physics for the years 1993 and 2003.Methods – The researchers selected eleven journals each from the list of journals from Journal Citation Reports 2004 for the categories “Oncology” and “Condensed Matter Physics” using a systematic sampling technique to ensure journals with vary ingimpact factors were included. All references from these 22 journals were retrieved for the years 1993 and 2003 by searching three databases: Web of Science, INSPEC, and PubMed. Only research articles were included for the purpose of the study. From these, a stratified random sample was created to proportionally represent the content of each journal (oncology 1993: 234 references, 2003: 259 references; condensed matter physics 1993: 358 references, 2003: 364 references. In November of 2005, citations counts were obtained for all articles from Web of Science, Scopus and GoogleScholar. Due to the small sample size and skewed distribution of data, non‐parametric tests were conducted to determine whether significant differences existed between sets.Main Results – For 1993, mean citation counts were highest in Web of Science for both oncology (mean = 45.3, SD = 77.4 and condensed matter physics (mean = 22.5, SD= 32.5. For 2003, mean citation counts were higher in Scopus for oncology (mean = 8.9,SD = 12.0, and in Web of Science for condensed matter physics (mean = 3.0, SD =4.0. There was not enough data for the set of citations from Scopus for condensed matter physics for 1993 and it was therefore excluded from analysis. A Friedman test

    Traditionally, the most commonly used source of bibliometric data is the Thomson ISI Web of Knowledge, in particular the (Social) Science Citation Index and the Journal Citation Reports, which provide the yearly Journal Impact Factors. This database used for the evaluation of researchers is not advantageous in the humanities, mainly because books, conference papers, and non-English journals, which are an important part of scientific activity, are not (well) covered. This paper presents the use of an alternative source of data, Google Scholar, and its benefits in calculating citation metrics in the humanities. Because of its broader range of data sources, the use of Google Scholar generally results in more comprehensive citation coverage in the humanities. This presentation compares and analyzes some international case studies with ISI Web of Knowledge and Google Scholar. The fields of economics, geography, social sciences, philosophy, and history are focused on to illustrate the differences of results between these two databases. To search for relevant publications in the Google Scholar database, the use of "Publish or Perish" and of CleanPoP, which the author developed to clean the results, are compared.

This study examined academic collaboration among the authors of articles published in Iranian English language journals of ministry of health, indexed in the Web of Science and its correlation with article citations, 2005-2011. Methods: This study was a descriptive-analytical and cross-sectional study. The data were collected using a researcher-designed checklist. The study population was 6388 articles from 21 Iranian English language journals of ministry of health, indexed in the Web of Science. Data were collected by referring to each journal and counting the number of authors and citations allocated to any article. The obtained data were analyzed by SPSS and Excel software. Results: A total of 6388 articles published in 21 journals were analyzed according to the intended criteria. %17.8 of journals was monthly, %19.6 was tow-monthly and% 62.7 was quarterly. On average, 4.37 authors collaborated in writing each article. The mean of collaborative coefficient was 0.67. There was positively significant correlation between the number of authors and the number of citations to each article. Conclusion: The academic collaboration among the authors of examined articles enjoyed a favorable status, which is indicative of spirit of teamwork among the Iranian researchers. However, the rate of citations to articles in the examined journals was not in a good condition; hence, the factors affecting citation to articles, especially academic collaboration between researchers should be taken into consideration.

    To evaluate scientific papers published by Korean radiologists in the Science Citation Index Expanded (SCIE) radiology journals, between 1986 and 2010. The Institute for Scientific Information Web of Knowledge-Web of Science (SCIE) database was searched for all articles published by Korean radiologists, in SCIE radiology journals, between 1986 and 2010. We performed the analysis by typing 'Korea' and 'radiol' in the address section and selecting the subject area of 'Radiology, Nuclear Medicine, and Medical Imaging' with the use of the general search function of the software. Analyzed parameters included the total number of publications, document types, journals, and institutions. In addition, we analyzed where Korea ranks, compared to other countries, in terms of the number of published articles. All these data were analyzed according to five time periods: 1986-1990, 1991-1995, 1996-2000, 2001-2005, and 2006-2010. Overall, 4974 papers were published by Korean radiologists, in 99 different SCIE journals, between 1986 and 2010, of which 4237 (85.2%) were article-type papers. Of the total 115395 articles, worldwide, published in radiology journals, Korea's share was 3.7%, with an upward trend over time (p < 0.005). The journal with the highest number of articles was the American Journal of Roentgenology (n 565, 13.3%). The institution which produced the highest number of publications was Seoul National University (n = 932, 22.0%). The number of scientific articles published by Korean radiologists in the SCIE radiology journals has increased significantly between 1986 and 2010. Korea was ranked 4th among countries contributing to radiology research during the last 5 years.

    2016-01-01

    Patent is not only a scientific and technical literature but also a legal document. An objective study of patent laws in the specific provisions of the patent cited behavior around the world is a foundation and premise for correct understanding of the patent citing behavior and the significance of patent citation in information science. This article translated and interpreted the provisions of the US Patent Statute, the European Patent Statute, the Japanese Patent Statute and the Chinese Patent Statute on the patent citing behavior. The legal function of the patent citation was clearly explained in the patent law field for the first time. In view of the current evaluation system of patent citation information are usually based on the "citation", this paper proposed that based on the relevant provisions of the patent citation behavior from the patent laws, the value of the patent shall be closely related to the "application" of the patent. The results also suggested that the research in citation behavior of patents and the corresponding frequency of citation should be of great informational significance in the analysis and prediction of the value of patents.%专利不仅是科技文献,更是法律文件,客观研读世界各国专利法对专利引用行为的具体规定,是正确认识专利引用行为及其产出的专利引文的情报学意义的基础和前提。本文翻译并解读了美国专利法规、欧洲专利法规、日本专利法规和中国专利法规有关专利引用行为的条款,首次在专利法视域下清晰地阐述了专利引文的法定功能。鉴于目前情报学界的专利引文评价指标体系通常以计量“被引”为主,本文大胆地提出:基于专利法对专利引用行为的相关规定,专利的价值应当与专利的“施引”密切相关性,研究专利的引用行为及相应的施引频次,应当在分析和预见专利价值方面具有重要的情报学意义。

    Full Text Available BACKGROUND: The impact of a scientific article is proportional to the citations it has received. In this study, we set out to identify the most cited works in epileptology in order to evaluate research trends in this field. METHODS: According to the Web of Science database, articles with more than 400 citations qualify as "citation classics". We conducted a literature search on the ISI Web of Science bibliometric database for scientific articles relevant to epilepsy. RESULTS: We retrieved 67 highly cited articles (400 or more citations, which were published in 31 journals: 17 clinical studies, 42 laboratory studies, 5 reviews and 3 classification articles. Clinical studies consisted of epidemiological analyses (n=3, studies on the clinical phenomenology of epilepsy (n=5 – including behavioral and prognostic aspects – and articles focusing on pharmacological (n=6 and non-pharmacological (n=3 treatment. The laboratory studies dealt with genetics (n=6, animal models (n=27, and neurobiology (n=9 – including both neurophysiology and neuropathology studies. The majority (61% of citation classics on epilepsy were published after 1986, possibly reflecting the expansion of research interest in laboratory studies driven by the development of new methodologies, specifically in the fields of genetics and animal models. Consequently, clinical studies were highly cited both before and after the mid 80s, whilst laboratory researches became widely cited after 1990. CONCLUSIONS: Our study indicates that the main drivers of scientific impact in the field of epileptology have increasingly become genetic and neurobiological studies, along with research on animal models of epilepsy. These articles are able to gain the highest numbers of citations in the time span of a few years and suggest potential directions for future research.

    2014-10-01

    An overview of the Data Citation Index is provided. Thomson Reuters developed this resource in response to a stated desire among members of the research community for increased attribution of non-traditional scholarly output. Launched in October of 2012 on the Web of science research platform, its aims include linking published research articles to their underlying data sets and tracking the citation of the data, as well as encouraging bibliographic citation of data. Cross-disciplinary search capabilities in the Index enable new possibilities for data discovery and synthesis. Data repositories are evaluated with respect to various selection criteria, with particular attention to their relevance to scientific and scholarly research. Index content reflects current data deposition practices. As data citation standards and practices continue to move toward widespread formalization and adoption, the initiative seeks to address issues of data citation, reuse, and author credit in a developing climate.

    Full Text Available Objective – To test whether acquiring books written by authors of highly cited journal articles is an effective method for building a collection in the social sciences.Design – Comparison Study.Setting – Academic library at a public university in the US.Subjects – A total of 1,359 book titles, selected by traditional means (n=1,267 or based on citation analysis (n=92.Methods – The researchers identified highly‐ranked authors, defined as the most frequently cited authors publishing in journals with an impact factor greater than one, with no more than six journals in any category, using 1999 ISI data. They included authors in the categories Business, Anthropology, Criminology & Penology, Education & Education Research, Political Science, Psychology, Sociology/Anthropology, and General Social Sciences. The Books in Print bibliographic tool was searched to identify monographs published by these authors, and any titles not already owned were purchased. All books in the study were available to patrons by Fall 2005. The researchers collected circulation data in Spring 2007, and used it to compare titles acquired by this method with titles selected by traditional means.Main Results – Overall, books selected by traditional methods circulated more than those selected by citation analysis, with differences significant at the .001 level. However, at the subject category level, there was no significant difference at the .05 level. Most books selected by the test method circulated one to two times.Conclusion – Citation analysis can be an effective method for building a relevant book collection, and may be especially effective for identifying works relevant to a discipline beyond local context.

  3. Towards the discovery of citation cartels in citation networks

    Full Text Available In this perspective, our goal is to present and elucidate a thus far largely overlooked problem that is arising in scientific publishing, namely the identification and discovery of citation cartels in citation networks. Taking from the well-known definition of a community in the realm of network science, namely that people within a community share significantly more links with each other as they do outside of this community, we propose that citation cartels are defined as groups of authors that cite each other disproportionately more than they do other groups of authors that work on the same subject. Evidently, the identification of citation cartels is somewhat different, although similar to the identification of communities in networks. We systematically expose the problem, provide theoretical examples, and outline an algorithmic guide on how to approach the subject.

  6. The assessment of science: the relative merits of post-publication review, the impact factor, and the number of citations.

    Science.gov (United States)

    Eyre-Walker, Adam; Stoletzki, Nina

    2013-10-01

    The assessment of scientific publications is an integral part of the scientific process. Here we investigate three methods of assessing the merit of a scientific paper: subjective post-publication peer review, the number of citations gained by a paper, and the impact factor of the journal in which the article was published. We investigate these methods using two datasets in which subjective post-publication assessments of scientific publications have been made by experts. We find that there are moderate, but statistically significant, correlations between assessor scores, when two assessors have rated the same paper, and between assessor score and the number of citations a paper accrues. However, we show that assessor score depends strongly on the journal in which the paper is published, and that assessors tend to over-rate papers published in journals with high impact factors. If we control for this bias, we find that the correlation between assessor scores and between assessor score and the number of citations is weak, suggesting that scientists have little ability to judge either the intrinsic merit of a paper or its likely impact. We also show that the number of citations a paper receives is an extremely error-prone measure of scientific merit. Finally, we argue that the impact factor is likely to be a poor measure of merit, since it depends on subjective assessment. We conclude that the three measures of scientific merit considered here are poor; in particular subjective assessments are an error-prone, biased, and expensive method by which to assess merit. We argue that the impact factor may be the most satisfactory of the methods we have considered, since it is a form of pre-publication review. However, we emphasise that it is likely to be a very error-prone measure of merit that is qualitative, not quantitative.

  7. Towards Semantic e-Science for Traditional Chinese Medicine

    2007-05-01

    Full Text Available Abstract Background Recent advances in Web and information technologies with the increasing decentralization of organizational structures have resulted in massive amounts of information resources and domain-specific services in Traditional Chinese Medicine. The massive volume and diversity of information and services available have made it difficult to achieve seamless and interoperable e-Science for knowledge-intensive disciplines like TCM. Therefore, information integration and service coordination are two major challenges in e-Science for TCM. We still lack sophisticated approaches to integrate scientific data and services for TCM e-Science. Results We present a comprehensive approach to build dynamic and extendable e-Science applications for knowledge-intensive disciplines like TCM based on semantic and knowledge-based techniques. The semantic e-Science infrastructure for TCM supports large-scale database integration and service coordination in a virtual organization. We use domain ontologies to integrate TCM database resources and services in a semantic cyberspace and deliver a semantically superior experience including browsing, searching, querying and knowledge discovering to users. We have developed a collection of semantic-based toolkits to facilitate TCM scientists and researchers in information sharing and collaborative research. Conclusion Semantic and knowledge-based techniques are suitable to knowledge-intensive disciplines like TCM. It's possible to build on-demand e-Science system for TCM based on existing semantic and knowledge-based techniques. The presented approach in the paper integrates heterogeneous distributed TCM databases and services, and provides scientists with semantically superior experience to support collaborative research in TCM discipline.

    2009-01-01

    Recently, aggregated journal-journal citation networks were made accessible from the perspective of each journal included in the Science Citation Index see (http://www.leydesdorff.net/). The local matrices can be used to inspect the relevant citation environment of a journal using statistical analysis and visualization techniques from social network analysis. The inspection gives an answer to the question what the local impact of this and other journals in the environment is. In this study the citation environment of Angewandte Chemie was analysed. Angewandte Chemie is one of the prime chemistry journals in the world. Its environment was compared with that of the Journal of the American Chemical Society. The results of the environment analyses give a detailed insight into the field-embeddedness of Angewandte Chemie. The impacts of the German and international editions of this journal are compared.

  13. Aberration of the Citation.

    Science.gov (United States)

    Moustafa, Khaled

    2016-01-01

    Multiple inherent biases related to different citation practices (for e.g., self-citations, negative citations, wrong citations, multi-authorship-biased citations, honorary citations, circumstantial citations, discriminatory citations, selective and arbitrary citations, etc.) make citation-based bibliometrics strongly flawed and defective measures. A paper can be highly cited for a while (for e.g., under circumstantial or transitional knowledge), but years later it may appear that its findings, paradigms, or theories were untrue or invalid anymore. By contrast, a paper may remain shelved or overlooked for years or decades, but new studies or discoveries may actualize its subject at any moment. As citation-based metrics are transformed into "commercial activities," the "citation credit" should be considered on a commercial basis too, in the sense that "citation credit" should be shared out as a "citation dividend" by shareholders (coauthors) averagely or proportionally to their contributions but not fully appropriated by each of them. At equal numbers of citations, the greater number of authors, the lower "citation credit" should be and vice versa. Overlooking the presence of distorted and subjective citation practices makes many people and administrators "obsessed" with the number of citations to such an extent to run after "highly cited" authors and to create specialized citation databases for commercial purposes. Citation-based bibliometrics, however, are unreliable and unscientific measures; citation counts do not mean that a more cited work is of a higher quality or accuracy than a less cited work because citations do not measure the quality or accuracy. Citations do not mean that a highly cited author or journal is more commendable than a less cited author or journal. Citations are not more than countable numbers: no more, no less.

    A bibliometric study was carried out to describe the scientific production on cancer written by Peruvians and published in international health journals, as well as to assess the scientific collaboration networks. It included articles on cancer written in Peru between the years 2000 and 2011 and published in health journals indexed in SCOPUS or Science Citation Index Expanded. In the 358 articles identified, an increase in the production was seen, from 4 articles in 2000 to 57 in 2011.The most studied types were cervical cancer (77 publications); breast cancer (53), and gastric cancer (37). The National Institute of Neoplastic Diseases (INEN) was the most productive institution (121 articles) and had the highest number of collaborations (180 different institutions). 52 clinical trials were identified, 29 of which had at least one author from INEN. We can conclude that, cancer research is increasing in Peru, the INEN being the most productive institution, with an important participation in clinical trials.

    BACKGROUND: The monosialoganglioside (GM1) is a popular topic of research but the bibliometric analysis of GM1 over the decades in Science Citation Index-Expanded (SCI-E) remains poorly understood.OBJECTIVE: To identify the global research and to improve the understanding of research trends in the GM1 field from 1942 to 2011. DESIGN: A bibliometric study. DATA RETRIEVAL: We performed a bibliometric analysis based on the SCI-E published by the Institute of Scientific Information. INCLUSIVE CRITERIA: Articles closely related to GM1 were included. Exclusive criteria: (1) Articles related to gangliosidosis, disialo-ganglioside, trisialo-ganglioside or ganglioside GQIb. (2) Document types such as meeting abstracts, reviews, proceedings papers, notes, and letters. MAIN OUTCOME MEASURES: (1) Type of publication output; (2) number of author outputs; (3) distribution of output in subject categories; (4) publication distribution of countries; (5) distribution of output in journals, and (6) distribution of citations in each decade.RESULTS: During 1942 to 2011, there were 10 126 papers on GM1 that were added to the SCI. Articles (8 004) were the most frequently used document type comprising 79.0%, followed by meeting abstracts, reviews and proceedings papers. Research on GM1 could be found in the SCI from 1942, it was developed in the 1970s, greatly increased in the 1980s, and reached a peak in the 1990s, and it was slightly decreased in 2000. The distribution of subject categories showed that GM1 research covered both clinical and basic science research. The USA, Japan, and Germany were the three most productive countries, and the publication numbers in the USA were highest in all decades. The Journal of Biological Chemistry, Journal of Neurochemistry and Biochemistry were core subject journals in GM1 studies in each decade. CONCLUSION: This study highlights the topics in GM1 research that are being published around the world.

  18. On the evolution and utility of annual citation indices

    Khaleque, Abdul; Sen, Parongama

    2014-01-01

    We study the statistics of citations made to the top ranked indexed journals for Science and Social Science databases in the Journal Citation Reports using different measures. Total annual citation and impact factor, as well as a third measure called the annual citation rate are used to make the detailed analysis. We observe that the distribution of the annual citation rate has an universal feature - it shows a maximum at the rate scaled by half the average, irrespective of how the journals are ranked, and even across Science and Social Science journals, and fits well to log-Gumbel distribution. Correlations between different quantities are studied and a comparative analysis of the three measures is presented. The newly introduced annual citation rate factor helps in understanding the effect of scaling the number of citation by the total number of publications. The effect of the impact factor on authors contributing to the journals as well as on editorial policies is also discussed.

Keywords in English, Spanish, Italian and German, truncated terms (such as ‘bienn’, single letters (such as P, and numbers were combined to retrieve all possible citations. Additional filters to exclude citations to publications other than proceedings were applied to the P search results, which had accounted for 75% of the total results. The references remaining in the P search set were validated using Google Scholar and WorldCat. Finally, two random samples of 1,000 references were checked manually to determine the extent of false positives and false negatives in the results.Main Results – The study’s findings are presented for NSE and SSH separately, with 1.7% of NSE citations and 2.5% of SSH citations referring to conference proceedings. The total number of citations to proceedings has increased over the period 1980-2005, however, citations to proceedings in NSE and SSH as a proportion of all citations decreased during this time. A small increase in the average number of proceedings citations per paper was found for NSE and SSH. When this increase is compared to the overall increase in references per paper over this period, the share of proceedings citations per paper has decreased.

    Chen, Chaomei; Hou, Jianhua

    2010-01-01

    A multiple-perspective co-citation analysis method is introduced for characterizing and interpreting the structure and dynamics of co-citation clusters. The method facilitates analytic and sense making tasks by integrating network visualization, spectral clustering, automatic cluster labeling, and text summarization. Co-citation networks are decomposed into co-citation clusters. The interpretation of these clusters is augmented by automatic cluster labeling and summarization. The method focuses on the interrelations between a co-citation cluster's members and their citers. The generic method is applied to a three-part analysis of the field of Information Science as defined by 12 journals published between 1996 and 2008: 1) a comparative author co-citation analysis (ACA), 2) a progressive ACA of a time series of co-citation networks, and 3) a progressive document co-citation analysis (DCA). Results show that the multiple-perspective method increases the interpretability and accountability of both ACA and DCA n...

    2014-06-01

    Many observatories maintain bibliographies to document their impact and justify their continued funding[1], an effort that requires humans to discover and curate links between the scientific papers and the data that was used as evidence. The "Best Practices for Creating a Telescope Bibliography", endorsed by IAU C5 WG Libraries, recommends full text searching and human examination of each paper.[2] These efforts do not scale well.It is unlikely that articles published in journals from other disciples would be found. This is particularly a problem for solar physics, as solar data has applicability in astrophysics, space weather, and even the earth sciences.As our scientists are not on the editorial boards of the journals from other disciplines, we can't ensure proper attribution to allow these relationships to be discovered via full text searching.To better deal with tracking cross-discipline data usage, a number of groups have come up with guidelines and principles for data citation. In 2012, the National Academy's Board on Research Data and Information released the report "For Attribution-Developing Data Attribution and Citation Practices and Standards" [3] and it was followed last year by the CODATA-ICSTI report "Out of Cite, Out of Mind".[4]Participants from a number of groups synthesized a single set of principles for data citation that could be endorsed by all groups involved in research.[5] Implementing these principles can help to improve the scientific ecosystem by giving proper attribution to all contributors to data, improving transparency and reproducability, and making data more easily reusable to both astronomers and other researchers.We will present the Joint Declaration of Data Citation Principles, discuss the implications of them for astronomical data, and recommend steps towards implementation.References:[1] Accomazzi, et.al, 2012. http://adsabs.harvard.edu/abs/2012SPIE.8448E..0KA[2] Bishop, Grothkopf & Lagerstrom, 2012. http://iau-commission5

    Full Text Available In one of the online publications of Nature Publishing Group, Ball discussed issues relating to negative citation of science publications.[1] He identified from the work of Alexander Oettl, an economist, at the Georgia Institute of Technology in Atlanta that the rate at which negative citations appear in the literature is low but not negligible. In the work of Alexander Oettl, the study team checked through citations in articles published in the Journal of Immunology. Immunologists helped the team to manually classifying “negative” citations. Overall, it was found that only about 2.4% of the citations were “negative.” Although the paper concluded that the rate of the negative citation was low but not negligible, one may be tempted to conclude that the problem with citations analytics is a minor one. Unfortunately, this may not be the real situation because the significant amount of critiques on citation analytics indicates that the problem is not minor. Read more. . .

    Bornmann and Leydesdorff (in press) proposed methods based on Web-of-Science data to identify field-specific excellence in cities where highly-cited papers were published more frequently than can be expected. Top performers in output are cities in which authors are located who publish a number of highly-cited papers that is statistically significantly higher than can be expected for these cities. Using papers published between 1989 and 2009 in information science improvements to the methods of Bornmann and Leydesdorff (in press) are presented and an alternative mapping approach based on the indicator I3 is introduced here.

    2010-02-01

    This study explores explicit and implicit gender-science stereotypes and affective attitudes towards science in a sample of Chinese secondary school students. The results showed that (1) gender-science stereotyping was more and more apparent as the specialization of science subjects progresses through secondary school, becoming stronger from the 10th grade; girls were more inclined to stereotype than boys while this gender difference decreased with increasing grade; (2) girls tend to have an implicit science-unpleasant/humanities-pleasant association from the 8th grade, while boys showed a negative implicit attitude towards science up to the 11th grade. In self-report, girls preferred humanities to science, while boys preferred science to humanities; (3) implicit affective attitude was closely related to implicit stereotype. In particular, implicit affective attitude has a stronger predictive power on stereotype than the other way around, the result of which may have more significance for girls.

  14. Transnational science during the Cold War: the case of Chinese/American scientists.

    2010-06-01

    This essay examines the experiences of about five thousand Chinese students/scientists in the United States after the Communist takeover of mainland China in 1949. These experiences illustrate the often hidden transnational movements of people, instruments, and ideas in science and technology across the Iron Curtain during the Cold War. I argue that those hundreds who returned to China represented a partial "Americanization" of Chinese science and technology, while the rest of the group staying in the United States contributed to a transnationalization of the American scientific community.

    Conclusion: The presence of correlation between citations and bookmarks implies that bookmarks can represent article's scientific impact. However, according to the weakness of this correlation, replacing these two indicators is not recommended the bookmarking data can be used as a supplementary metric in research evaluation and assessment of scientific impact. Bookmarked articles in comparison with those unbookmarked have been shown higher mean citation which reflect user's selectivity in article bookmarking and represent another aspect of altmetrics validity.

This paper study on Chinese monographs in Scientometrics, Informetrics and Bibliometrics (1987 ~ 2010), using metrology and statistics methods to analysis the total number, type and language and time distribution of the citation. By statistics we found the increase by year in the number of books and rapid growth of per book citations in near ten years. Most of the authors are male from colleges or universities and the proportion of co-author is 16.7%. The citation analysis results show that monographs cite papers most. Foreign literature also takes a large part.

    2011-01-01

    Nobel Prizes are commonly seen to be among the most prestigious achievements of our times. Based on mining several million citations, we quantitatively analyze the processes driving paradigm shifts in science. We find that groundbreaking discoveries of Nobel Prize Laureates and other famous scientists are not only acknowledged by many citations of their landmark papers. Surprisingly, they also boost the citation rates of their previous publications. Given that innovations must outcompete the rich-gets-richer effect for scientific citations, it turns out that they can make their way only through citation cascades. A quantitative analysis reveals how and why they happen. Science appears to behave like a self-organized critical system, in which citation cascades of all sizes occur, from continuous scientific progress all the way up to scientific revolutions, which change the way we see our world. Measuring the "boosting effect" of landmark papers, our analysis reveals how new ideas and new players can make their...

    2016-09-01

    Full Text Available Software is a critical part of modern research and yet there is little support across the scholarly ecosystem for its acknowledgement and citation. Inspired by the activities of the FORCE11 working group focused on data citation, this document summarizes the recommendations of the FORCE11 Software Citation Working Group and its activities between June 2015 and April 2016. Based on a review of existing community practices, the goal of the working group was to produce a consolidated set of citation principles that may encourage broad adoption of a consistent policy for software citation across disciplines and venues. Our work is presented here as a set of software citation principles, a discussion of the motivations for developing the principles, reviews of existing community practice, and a discussion of the requirements these principles would place upon different stakeholders. Working examples and possible technical solutions for how these principles can be implemented will be discussed in a separate paper.

  1. Time and Citation Networks

    CERN Document Server

    Clough, James R

    2015-01-01

    Citation networks emerge from a number of different social systems, such as academia (from published papers), business (through patents) and law (through legal judgements). A citation represents a transfer of information, and so studying the structure of the citation network will help us understand how knowledge is passed on. What distinguishes citation networks from other networks is time; documents can only cite older documents. We propose that existing network measures do not take account of the strong constraint imposed by time. We will illustrate our approach with two types of causally aware analysis. We apply our methods to the citation networks formed by academic papers on the arXiv, to US patents and to US Supreme Court judgements. We show that our tools can reveal that citation networks which appear to have very similar structure by standard network measures turn out to have significantly different properties. We interpret our results as indicating that many papers in a bibliography were not directly...

    2015-01-01

    Citation networks have been widely used to study the evolution of science through the lenses of the underlying patterns of knowledge flows among academic papers, authors, research sub-fields, and scientific journals. Here we focus on citation networks to cast light on the salience of homophily, namely the principle that similarity breeds connection, for knowledge transfer between papers. To this end, we assess the degree to which citations tend to occur between papers that are concerned with seemingly related topics or research problems. Drawing on a large data set of articles published in the journals of the American Physical Society between 1893 and 2009, we propose a novel method for measuring the similarity between articles through the statistical validation of the overlap between their bibliographies. Results suggest that the probability of a citation made by one article to another is indeed an increasing function of the similarity between the two articles. Our study also enables us to uncover missing ci...

    2014-12-01

    This essay explores the variegated roles played by racial, eugenic, and Social Darwinist discourse in China over roughly the last century. Using Japan as a parallel for comparison, it analyzes the introduction of the term "eugenics" into Japanese and Chinese. It then locates the deployment of eugenics and Social Darwinism as counterimperial discourse in East Asia. It offers a brief history of eugenics thinking in China across the twentieth century, focusing on the Chinese eugenicist Pan Guangdan, who used race as a category of analysis yet without any sense of hierarchy. He was critically aware of the scientific basis of eugenics and helped craft the study of eugenics in China, from biology to sociology, from economics to ethnology.

  16. Data Identifiers, Versioning, and Micro-citation

    Science.gov (United States)

    Parsons, M. A.; Duerr, R. E.

    2012-12-01

    Data citation, especially using Digital Object Identifiers (DOIs), is an increasingly accepted scientific practice. For example, the AGU Council asserts that data "publications" should "be credited and cited like the products of any other scientific activity," and Thomson Reuters has recently announced a data citation index built from DOIs assigned to data sets. Correspondingly, formal guidelines for how to cite a data set (using DOIs or similar identifiers/locators) have recently emerged, notably those from the international DataCite consortium, the UK Digital Curation Centre, and the US Federation of Earth Science Information Partners. These different data citation guidelines are largely congruent. They agree on the basic practice and elements of data citation, especially for relatively static, whole data collections. There is less agreement on some of the more subtle nuances of data citation. They define different methods for handling different data set versions, especially for the very dynamic, growing data sets that are common in Earth Sciences. They also differ in how people should cite specific, arbitrarily large elements, "passages," or subsets of a larger data collection, i.e., the precise data records actually used in a study. This detailed "micro-citation", and careful reference to exact versions of data are essential to ensure scientific reproducibility. Identifiers such as DOIs are necessary but not sufficient for the precise, detailed, references necessary. Careful practice must be coupled with the use of curated identifiers. In this paper we review the pros and cons of different approaches to versioning and micro-citation. We suggest a workable solution for most existing Earth science data and suggest a more rigorous path forward for the future.

    Abt, Helmut A.

    2017-02-01

    I explore whether small or large teams produce the most important astronomical results, on average, using citation counts as our metric. I present evidence that citation counts indicate the importance of papers. For the 1343 papers published in A&A, ApJ, and MNRAS in 2012 January-February, I considered 4.5 years worth of citations. In each journal, there are larger citation counts for papers from large teams than from small teams by a factor of about 2. To check whether the results from 2012 were unusual, I collected data from 2013 for A&A and found it to be the same as that for 2012. Could the preponderance of papers by large teams be due to self-citations (i.e., citing and cited papers sharing one or more authors)? To answer this, I looked at 136 papers with one to 266 authors and discovered a linear relation that ranges from a 12.7% self-citation rate for single-author papers to a 45.9% self-citation rate for papers with 100 authors. Correcting for these factors is not enough to explain the predominance of the papers with large teams. Then I computed citations per author. While large teams average more citations than small ones by a factor of 2, individuals on small teams average more citations than individuals on large teams by a factor of 6. The papers by large teams often have far more data, but those by small teams tend to discuss basic physical processes.

    Science goals of telescopes are the fundament data of integrated modeling of astronomical telescopes. The differences between science goals are sources of telescope's diversities. Solar telescopes are a very special type in astronomical telescopes. Chinese Giant Solar Telescope1 (CGST) is currently designed to be an 8-meter Ring Interferometric Telescope (RIT). Even compare with the other solar telescopes, CGST is also an unusual telescope due to its ring aperture and distinctive science goals. As the initial data of integrated modeling of CGST, the main science cases determine the basic structure of the telescope as well as its working mode. This paper will discuss the importance of the primary science case in integrated modeling of CGST.

    The average citation career of a sample of 72 astronomers who received their PhD between 1977 and 1988, and who were employed in astronomy in 1994, is analysed using data from the Science Citation Index. The citation rates n_i(t) are fairly well represented by the assumption n_i(t)=alpha_i f(t) where f(t) is a `universal' function and alpha_i an individual `amplitude factor'. The shape of f shows that the citation rate 2 years after PhD is, on average, already one half of what it will be 12 years after PhD. Probability intervals are given for the later citation rate, for given rates early in the career. Early citation rates are found to have a modest but measurable predictive value.

    Neway, J M; Lancaster, F W

    1983-07-01

    The rate of citation duplication was examined in three databases: MEDLINE, BIOSIS, and LIFE SCIENCES COLLECTION. Duplicate citations were found to be more pertinent than unique citations. The duplicate citations came from a highly compact literature, while those from a single database were very widely scattered. The pertinent duplicated citations were more likely to be retrieved in searches that had more terms overall, had a higher percentage of thesaurus terms, and had terms which appeared in both title and abstract. These results suggest that the rate of duplication of citations in multidatabase searches may be used to rank output according to probable pertinence.

The present research aims to determine what proportion of web citations of Google search engine is related to formal and informal citation. Research method: Webometrics is the method used. The study is done on 1344 research articles of 98 open access journal, and the method that is used to extract the web citation from Google search engine is “Web / URL citation extraction". Findings: The findings showed that ten percent of the web citations of Google search engine are formal and informal citations. The highest formal citation in the Google search engine with 19/27% is in the field of library and information science and the lowest official citation by 1/54% is devoted to the field of civil engineering. The highest percentage of informal citations with 3/57% is devoted to sociology and the lowest percentage of informal citations by 0/39% is devoted to the field of civil engineering. Journal Citation is highest with 94/12% in the surgical field and lowest with 5/26 percent in the philosophy filed. Result: Due to formal and informal citations in the Google search engine which is about 10 percent and the reduction of this amount compared to previous research, it seems that track citations by this engine should be treated with more caution. We see that the amount of formal citation is variable in different disciplines. Cited journals in the field of surgery, is highest and in the filed of philosophy is lowest, this indicates that in the filed of philosophy, that is a subset of the social sciences, journals in scientific communication do not play a significant role. On the other hand, book has a key role in this filed

    Full Text Available 本研究提出一個測量期刊引用影響的整合式概念模型,並應用結構方程模式方法在圖書資訊學相關領域的50種期刊資訊進行以「期刊屬性」、「期刊易取性」及「期刊多樣性」等三項為「期刊引用」的前置因素理論模型的實證。整體模型的可解釋變異量為39.4%,其中測量模型的結果:以文獻篇數測量「期刊屬性」,以文件獲取性測量「期刊易取性」,及主題多樣化來測量「期刊多樣性」具顯著效果;而影響係數、立即指數及全部引用數來測量「期刊引用」,則均具顯著效果。結構模型的結果:「期刊引用」受到「期刊多樣性」的影響,但「期刊屬性」與「期刊易取性」則不具顯著性影響。The study proposes an integrated conceptual model to assess the journal citation impact. The antecedent factors include journal attributes, journal accessibility, and journal diversity. The structural equation modeling (SEM with partial least square (PLS is applied to conduct the empirical study within the fifty journals in the field of library and information science. The result shows that the antecedent factors account for 39.4% of the variance in journal citation. The result of measurement model shows that the number of articles is a good indicator for journal attributes; document availability is a good indicator for journal accessibility; and subject variety is a good indicator for journal diversity. As for the journal citation, three indicators include impact factor, immediacy index, and total citations are all good indicators. Moreover, the result of structural model shows that journal citation is significantly influenced by journal diversity, while there is no significant effect of journal attributes and journal accessibility.

    Currently there is considerable interest among oncologists to find anticancer drugs in Chinese herbal medicine (CHM).In the past, clinical data showed that some herbs possessed anticancer properties, but western scientists have doubted the scientific validity of CHM due to the lack of scientific evidence from their perspective. Recently there have been encouraging results, from a western perspective, in the cancer research field regarding the anticancer effects of CHM. Experiments showed that CHM played its anticancer role by inducing apoptosis and differentiation, enhancing the immune system, inhibiting angiogenesis, reversing multidrug resistance (MDR), etc. Clinical trials demonstrated that CHM could improve survival, increase tumor response, improve quality of life, or reduce chemotherapy toxicity, although much remained to be determined regarding the objective effects of CHM in human in the context of clinical trials. Interestingly, both laboratory experiments and clinical trials have demonstrated that when combined with chemotherapy, CHM could raise the efficacy level and lower toxic reactions. These facts raised the feasibility of the combination of herbal medicines and chemotherapy, although much remained to be investigated in this area.

    2016-01-01

    A paradigm change in scholarly communication is underway. Supporting Open Science, an effort to make scientific research data accessible to all interested parties by openly publishing research and encouraging others to do the same thereby making it easier to communicate scientific knowledge, is a part of the change that has become increasingly important for (digital) libraries. Digital libraries are able to play a significant role in enabling Open Science by facilitating data sharing, discovery and re-use. Because data citation is often mentioned as one incentive for data sharing, enabling data citation is a crucial feature of research data services. In this article we present a case study of data citation services for the High-Energy Physics (HEP) community using digital library technology. Our example shows how the concept of data citation is implemented for the complete research workflow, covering data production, publishing, citation and tracking of data reuse. We also describe challenges faced and distil...

  2. Student Perceptions of the Integrated `Science Education' Major in Some Chinese Universities

    Science.gov (United States)

    Zhang, Hongshia; He, Huachun

    2012-09-01

    The integrated science education major has been implemented for a decade in China. An investigation was conducted in 2010 to find out students' satisfaction with the programme. Participants included 27 senior students and 25 past students from six normal universities. Results show very low satisfaction. Identified reasons include the fact that the curriculum did not reflect the intended integration objectives of the major, and that the quality of science educators was inadequate to teach integrated courses. The most unsatisfactory aspects relate to the treatment of the nature of science, the integration of subject matters, and students' experience of inquiry learning in terms of both curriculum content and teaching methods. In addition to establishing an effective evaluation system, a more fundamental suggestion is to change the current normal college-based Chinese teacher education system especially in the science education sector.

To our surprise, we find that the apparently uncorrelated measures, even when defined in an arbitrary manner, show strong correlations. This is checked over all the years considered. Impact factor being one of these measures, the present work raises the question whether it is actually a nearly perfect index as claimed often. In addition, we study the distributions of the different indices which also behave similarly.

    2016-01-01

    The relationship between traditional metrics of research impact (e.g., number of citations) and alternative metrics (altmetrics) such as Twitter activity are of great interest, but remain imprecisely quantified. We used generalized linear mixed modeling to estimate the relative effects of Twitter activity, journal impact factor, and time since publication on Web of Science citation rates of 1,599 primary research articles from 20 ecology journals published from 2012-2014. We found a strong positive relationship between Twitter activity (i.e., the number of unique tweets about an article) and number of citations. Twitter activity was a more important predictor of citation rates than 5-year journal impact factor. Moreover, Twitter activity was not driven by journal impact factor; the 'highest-impact' journals were not necessarily the most discussed online. The effect of Twitter activity was only about a fifth as strong as time since publication; accounting for this confounding factor was critical for estimating the true effects of Twitter use. Articles in impactful journals can become heavily cited, but articles in journals with lower impact factors can generate considerable Twitter activity and also become heavily cited. Authors may benefit from establishing a strong social media presence, but should not expect research to become highly cited solely through social media promotion. Our research demonstrates that altmetrics and traditional metrics can be closely related, but not identical. We suggest that both altmetrics and traditional citation rates can be useful metrics of research impact.

    Full Text Available The article is devoted to the research of the prag-matic aspect of citation in fictional text from the in-tertextual point of view. The theory of intertextuality was formed in the works of M.Bakhtin and devel-oped by Y. Kristeva after the analysis of the works of post-modern writers. So allusion and citation began to be investigated not from the philology point of view only but from the linguistics as well. The pur-pose of the article is to investigate the pragmatic aspect of citation which includes also the investiga-tion of its pragmatic functions. Different views on the citation classification are also mentioned in the article as it is an actual problem in modern linguis-tics. Novels by British writer J. Fforde are the mate-rial for the investigation article because they pos-sess a big amount of intertextual inclusion in the text in general and citation in particular.

    This paper examines the proximity of authors to those they cite using degrees of separation in a co-author network, essentially using collaboration networks to expand on the notion of self-citations. While the proportion of direct self-citations (including co-authors of both citing and cited papers) is relatively constant in time and across specialties in the natural sciences (10% of citations) and the social sciences (20%), the same cannot be said for citations to authors who are members of the co-author network. Differences between fields and trends over time lie not only in the degree of co-authorship which defines the large-scale topology of the collaboration network, but also in the referencing practices within a given discipline, computed by defining a propensity to cite at a given distance within the collaboration network. Overall, there is little tendency to cite those nearby in the collaboration network, excluding direct self-citations. By analyzing these social references, we characterize the social...

    2010-01-01

    A citation-based indicator for interdisciplinarity has been missing hitherto among the set of available journal indicators. In this study, we investigate betweenness centrality, entropy, the Gini coefficient, and more recently proposed measures for diversity that combine the statistics of vectors and distances in networks, in terms of their potential to fill this gap. The effects of various normalizations are specified and measured using the matrix of 8,207 journals contained in the Journal Citation Reports of the (Social) Science Citation Index. Betweenness centrality in (1-mode) affiliations networks provides an indicator outperforming betweenness in the (2-mode) citation network. Entropy as a vector-based indicator performs better than the Gini coefficient, but is sensitive to size. Science and Nature, for example, are indicated at the top of the list. The new diversity measure provides reasonable results when (1 - cosine) is assumed as a measure for the distance, but results using Euclidean distances are ...

    The epoch-making research by H. J. Bhabha has gained eponymous status synonymous with his name and international fame. Out of the 427 eponymous bibliographic records for H. J. Bhabha retrieved from the Science Citation Index (1982-2002), majority of the records were for: bhabha scattering (290), angle bhabha scattering (42), small angle bhabha scattering (21), radiative bhabha scattering (17), large-angle bhabha scattering (16), resonant bhabha scattering (12), and low-angle bhabha scattering...

    2013-01-01

    Citation networks form directed acyclic graphs. The transitive reduction of such a DAG removes all edges in the graph that are implied by transitivity, but retains the causal structure of the original network. We investigate how the degree distribution, clustering coefficients and relationship between time of publication and degree (representing citation count) are changed under transitive reduction. We show that models which accurately reproduce the degree distribution of a citation network before transitive reduction may not do so afterwards and hence suggest that these models fail to accurately capture the causal structure of the network. We also investigate how the citation count of individual papers is changed and suggest that information about the types of citations a paper receives can be inferred from the number of citations which are retained after transitive reduction. These methods are tested on citation networks from the hep-th and hep-ph sections of the arXiv repository, and all data has been mad...

  12. Science, technique, technology: passages between matter and knowledge in imperial Chinese agriculture.

    Bray, Francesca

    2008-09-01

    Many historians today prefer to speak of knowledge and practice rather than science and technology. Here I argue for the value of reinstating the terms science, techniques and technology as tools for a more precise analysis of governmentality and the workings of power. My tactic is to use these three categories and their articulations to highlight flows between matter and ideas in the production and reproduction of knowledge. In any society, agriculture offers a wonderfully rich case of how ideas, material goods and social relations interweave. In China agronomy was a science of state, the basis of legitimate rule. I compare different genres of agronomic treatise to highlight what officials, landowners and peasants respectively contributed to, and expected from, this charged natural knowledge. I ask how new forms of textual and graphic inscription for encoding agronomic knowledge facilitated its dissemination and ask how successful this knowledge proved when rematerialized and tested as concrete artefacts or techniques. I highlight forms of innovation in response to crisis, and outline the overlapping interpretative frameworks within which the material applications of Chinese agricultural science confirmed and extended its truth across space and time.

    Identifying citation classics in the field is one of the key methodologies used to conduct a systematic evaluation of research performance. The objective of this study was to determine the most frequently cited articles published in journals that are placed under the 'respiratory system' subject category (Institute for Scientific Information (ISI) Journal Citation Reports) and to compare them with the most frequently cited respiratory-related articles published in any journal, regardless of subject category. The authors utilized the ISI Journal Citation Reports: Science Edition 2010 database in April 2012 to determine the most frequently cited articles by respiratory system subject category and by respiratory-related keywords. The top 50 most-cited articles were identified in each category and evaluated according to various characteristics. The majority of these papers originated from the United States. The median numbers of citations for the top 50 cited articles stratified by respiratory system subject category and respiratory-related keywords were 841.5 and 2701, respectively. Half of the top 50 cited articles identified by respiratory-related keywords were published in general medical or basic science journals, whereas only three out of these were published in journals under the respiratory system subject category in ISI Journal Citation Reports. In summary, respiratory-related articles published in general medical or science journals attracted more citations than those published in the specific respiratory journals.

    Current science evaluation still relies on citation performance, despite criticisms of purely bibliometric research assessments. Biological taxonomy suffers from a drain of knowledge and manpower, with poor citation performance commonly held as one reason for this impediment. But is there really such a citation impediment in taxonomy? We compared the citation numbers of 306 taxonomic and 2291 non-taxonomic research articles (2009–2012) on mosses, orchids, ciliates, ants, and snakes, using Web of Science (WoS) and correcting for journal visibility. For three of the five taxa, significant differences were absent in citation numbers between taxonomic and non-taxonomic papers. This was also true for all taxa combined, although taxonomic papers received more citations than non-taxonomic ones. Our results show that, contrary to common belief, taxonomic contributions do not generally reduce a journal's citation performance and might even increase it. The scope of many journals rarely featuring taxonomy would allow editors to encourage a larger number of taxonomic submissions. Moreover, between 1993 and 2012, taxonomic publications accumulated faster than those from all biological fields. However, less than half of the taxonomic studies were published in journals in WoS. Thus, editors of highly visible journals inviting taxonomic contributions could benefit from taxonomy's strong momentum. The taxonomic output could increase even more than at its current growth rate if: (i) taxonomists currently publishing on other topics returned to taxonomy and (ii) non-taxonomists identifying the need for taxonomic acts started publishing these, possibly in collaboration with taxonomists. Finally, considering the high number of taxonomic papers attracted by the journal Zootaxa, we expect that the taxonomic community would indeed use increased chances of publishing in WoS indexed journals. We conclude that taxonomy's standing in the present citation-focused scientific landscape could

    Background: Students' daily-life experiences may render favorable effects on the students' affective domain like interest, enthusiasm, motivation, joy, curiosity, awareness, and eagerness to learn science as not commonly found in the classroom environment. However, no rigorous research has been reported on those aspects in Mainland China despite many recent studies done in various Western countries. Purpose: This paper aims to report and compare the science-related experiences of ninth-graders from two places (in Urumqi City of Xinjiang province and Shanghai) in China through a large-scale survey of their junior secondary three students. Sample: The sample consists of 4115 students in Urumqi City (from 28 schools) and Shanghai (from 25 schools). Design and methods: This study adopted a Likert scale questionnaire instrument, as translated from the international Relevance Of Science Education (ROSE) Project. From a confirmatory factor analysis of the data, we identify and focus on six factors which are directly correlated with students' science-related experiences outside school environment in Xinjiang and Shanghai and employ relevant factor scores to compare the gender, regional, and socioeconomic effects. Results: As revealed by the t-test, gender and regional differences were statistically significant in affecting (1) students' outdoor living experience, (2) hands-on experience of transportation, and (3) their daily-life experience with do-it-yourself tools and models. In all three aspects, boys and Xinjiang students possessed richer experiences than girls and Shanghai students, respectively. Conclusions: Based on ANOVA tests, Shanghai students' out-of-school science-related experiences were more often significantly affected by various socioeconomic variables (including their parents' education and occupation and their family income) than Xinjiang students. From cross-regional comparison, Chinese students had much fewer science-related experiences than those of

    Aggregated journal-journal citation networks based on the Journal Citation Reports 2004 of the Science Citation Index (5968 journals) and the Social Science Citation Index (1712 journals) are made accessible from the perspective of any of these journals. The user is thus able to analyze the citation environment in terms of links and graphs. Furthermore, the local impact of a journal is defined as its share of the total citations in the specific journal's citation environments; the vertical size of the nodes is varied proportionally to this citation impact. The horizontal size of each node can be used to provide the same information after correction for within-journal (self)-citations. In the "citing" environment, the equivalents of this measure can be considered as a citation activity index which maps how the relevant journal environment is perceived by the collective of authors of a given journal. As a policy application, the mechanism of interdisciplinary developments among the sciences is elaborated for th...

    Summarizing the creation of Chinese military science ifctions from the beginning of the 20th century onward shows that, like any literature genre, military science ifctions also take root in the times, therefore relfect the political and military realities in that time period. From the late Qing Dynasty to the Republic of China, Chinese science and technology had been lagging behind those of advanced countries. As a result, Chinese military science ifctions then could only follow the cliché without any innovation. Approaching the contemporary times, as Chinese science and technology developed, themes of Chinese military science ifctions also became more enriched and original with more and more obvious achievements. Both national strategic need and need from teenagers require the outcome of a range of military science ifctions that can catch the audience’s eyes and raise national and military morale. It is our sincere hope that like the Chinese military science and technology, Chinese military science ifctions can in the future be listed among those top ones.%梳理从20世纪初开始的华语军事科幻小说创作,可知军事科幻和任何类型文学一样扎根于时代土壤,每个时期的军事科幻都反映那个时代的政治、军事现实。从晚清到民国时期,中国科技远远落后于世界先进水平,当时的中国军事科幻也只能使用外国作家写烂的题材,并无创新。越接近当代,中国科技实力越强,中国军事科幻的题材越丰富,越具有原创性,成就日渐可观。无论从国家战略层面,还是从青少年教育层面,都迫切需要一批既吸引观众,又能扬我国威、军威的军事科幻作品。希望我国的军事科幻和军事科技一样,早日跻身于世界前列。

    Full Text Available It is common to conduct collaborative research in science and technology. In particular, the development of big science, Internet, and globalization facilitated the scientific collaboration. This study used two databases, Web of Science and Journal Citation Reports as data sources. From the analysis of 320 papers in 16 journals in life sciences, the results showed that there is no significant correlation between the impact factor of journals and the number of authors. Moreover, there is no correlation of authors and the cited times, either. The number of authors and cited times in most papers are under 10 persons and 25 times, respectively.[Article content in Chinese

    Full Text Available This study investigates the indexed papers dated from 1996 to 2002, included in the Taiwan Humanities Citation Index (THCI. The goal is to explore disciplinary interflow of Library & Information Science (LIS studies in Taiwan. The results show that the researchers of LIS mostly cooperate with researchers and scholars in the fields of social science and engineering & technology. In addition, LIS researchers focusing on “Library & Information Technology” and “Reader Services” frequently cooperate with researchers from other disciplines. With regard to their citation behaviors, LIS researchers frequently cite literatures of the Social Science, Engineering & Technology, and History. Especially, the major of cited literatures are written in Chinese and published 5 to 10 years earlier than the citing papers.The LIS research topic, “Administration and Management”, has the largest COC (citation outside category index and WCOC (weighted citation outside category index. As an LIS research topic, “Administration and Management” might have relatively higher degree of disciplinary interflow. [Article content in Chinese

    Full Text Available This study aims to provide an overview of the citation rate of Wikipedia since its launch in 2004. It is worth noting that since its inception Wikipedia, the free international multi-lingual encyclopedia, has been subject to criticism (Fasoldt, 2004; Orlowski, 2005; Lipczynska, 2005. Wikipedia as a popular web resource appears in response to every keyword search on Google. One way to test the popularity of a web resource is to use citation analysis method to predict to what extend it is cited by scientific papers. This study tries to identify and quantify the number of citations to Wikipedia in the papers indexed by the ISI Web of Science, studying the citation behavior of authors who have published papers in journals indexed by this database. Another simple search was conducted in order to analyze the number of citations to Britannica in the Cited Work=(Britannica* AND Cited Year=(2004-2009. The result showed that Britannica was cited only 10 times by 10 different subject areas and only in English language documents. The data show that Wikipedia is cited 26 times more than Britannica. Although, the credibility and reliability of content of Wikipedia as an authoritative reference source was widely criticized (e.g., Lih, 2004; Andrew et al., 2005; Korfiatis, Poulos, & Bokos, 2006, it is cited more than Britannica. The significance of Wikipedia from a citation analysis point of view goes well beyond open access and enhanced opportunities for citation.

  3. Multiple Citation Indicators and Their Composite across Scientific Disciplines.

    2016-07-01

    Full Text Available Many fields face an increasing prevalence of multi-authorship, and this poses challenges in assessing citation metrics. Here, we explore multiple citation indicators that address total impact (number of citations, Hirsch H index [H], co-authorship adjustment (Schreiber Hm index [Hm], and author order (total citations to papers as single; single or first; or single, first, or last author. We demonstrate the correlation patterns between these indicators across 84,116 scientists (those among the top 30,000 for impact in a single year [2013] in at least one of these indicators and separately across 12 scientific fields. Correlation patterns vary across these 12 fields. In physics, total citations are highly negatively correlated with indicators of co-authorship adjustment and of author order, while in other sciences the negative correlation is seen only for total citation impact and citations to papers as single author. We propose a composite score that sums standardized values of these six log-transformed indicators. Of the 1,000 top-ranked scientists with the composite score, only 322 are in the top 1,000 based on total citations. Many Nobel laureates and other extremely influential scientists rank among the top-1,000 with the composite indicator, but would rank much lower based on total citations. Conversely, many of the top 1,000 authors on total citations have had no single/first/last-authored cited paper. More Nobel laureates of 2011-2015 are among the top authors when authors are ranked by the composite score than by total citations, H index, or Hm index; 40/47 of these laureates are among the top 30,000 by at least one of the six indicators. We also explore the sensitivity of indicators to self-citation and alphabetic ordering of authors in papers across different scientific fields. Multiple indicators and their composite may give a more comprehensive picture of impact, although no citation indicator, single or composite, can be expected to

    Citation distributions are crucial for the analysis and modeling of the activity of scientists. We investigated bibliometric data of papers published in journals of the American Physical Society, searching for the type of function which best describes the observed citation distributions. We used the goodness of fit with Kolmogorov-Smirnov statistics for three classes of functions: log-normal, simple power law and shifted power law. The shifted power law turns out to be the most reliable hypothesis for all citation networks we derived, which correspond to different time spans. We find that citation dynamics is characterized by bursts, usually occurring within a few years since publication of a paper, and the burst size spans several orders of magnitude. We also investigated the microscopic mechanisms for the evolution of citation networks, by proposing a linear preferential attachment with time dependent initial attractiveness. The model successfully reproduces the empirical citation distributions and accounts...

    Full Text Available Whilst their 'death' has often been certified, books remain highly important to most professions and academic disciplines. Analyses of citations received by epidemiologic texts may complement other views on epidemiology. The objective was to assess the number of citations received by some books of epidemiology and public health, as a first step towards studying the influence of epidemiological thought and thinking in academia. For this purpose, Institute for Scientific Information/ Thomson Scientific - Web of Science/ Web of Knowledgedatabase was consulted, in May 2006. The book by Rothman & Greenland appeared to have received the highest number of citations overall (over 8,000 and per year. The books by Kleinbaum et al, and by Breslow & Day received around 5,000 citations. In terms of citations per year the book by Sackett et al ranks 3rd, and the one by Rose, 4th of those included in this preliminary study. Other books which were influential in the classrooms collected comparatively less citations. Results offer a rich picture of the academic influences and trends of epidemiologic methods and reasoning on public health, clinical medicine and the other health, life and social sciences. They may contribute to assess epidemiologists' efforts to demarcate epidemiology and to assert epistemic authority, and to analyze some historical influences of economic, social and political forces on epidemiological research.

    Traditionally, scholarly impact and visibility have been measured by counting publications and citations in the scholarly literature. However, increasingly scholars are also visible on the Web, establishing presences in a growing variety of social ecosystems. But how wide and established is this presence, and how do measures of social Web impact relate to their more traditional counterparts? To answer this, we sampled 57 presenters from the 2010 Leiden STI Conference, gathering publication and citations counts as well as data from the presenters' Web "footprints." We found Web presence widespread and diverse: 84% of scholars had homepages, 70% were on LinkedIn, 23% had public Google Scholar profiles, and 16% were on Twitter. For sampled scholars' publications, social reference manager bookmarks were compared to Scopus and Web of Science citations; we found that Mendeley covers more than 80% of sampled articles, and that Mendeley bookmarks are significantly correlated (r=.45) to Scopus citation counts.

    2011-01-01

    This paper aims to identify whether different weighted PageRank algorithms can be applied to author citation networks to measure the popularity and prestige of a scholar from a citation perspective. Information Retrieval (IR) was selected as a test field and data from 1956-2008 were collected from Web of Science (WOS). Weighted PageRank with citation and publication as weighted vectors were calculated on author citation networks. The results indicate that both popularity rank and prestige rank were highly correlated with the weighted PageRank. Principal Component Analysis (PCA) was conducted to detect relationships among these different measures. For capturing prize winners within the IR field, prestige rank outperformed all the other measures.

    2011-12-01

    The validation of scientific results requires reproducible methods and data. Often, however, data sets supporting research articles are not openly accessible and interlinked. This analysis tests whether open sharing and linking of supporting data through the PANGAEA° data library measurably increases the citation rate of articles published between 1993 and 2010 in the journal Paleoceanography as reported in the Thomson Reuters Web of Science database. The 12.85% (171) of articles with publicly available supporting data sets received 19.94% (8,056) of the aggregate citations (40,409). Publicly available data were thus significantly (p=0.007, 95% confidence interval) associated with about 35% more citations per article than the average of all articles sampled over the 18-year study period (1,331), and the increase is fairly consistent over time (14 of 18 years). This relationship between openly available, curated data and increased citation rate may incentivize researchers to share their data.

    It is frequently claimed that the influence of behaviorism in general and of B. F. Skinner in particular, is declining. Data obtained from the Social Sciences Citation Index for the years 1966-1989 document that in the last twenty-four years the number of citations to the works of Skinner has been reasonably steady. There is no evidence of a decline in the absolute number of such citations, suggesting that claims of the demise of behaviorism may be, once again, premature.

    Full Text Available Using informetrics and citation analysis, the present study explores and compares characteristics and types of citations in the humanity journal articles that published in Taiwan. Research articles published in 2011, from top humanity journals, assessed by the Institute of Humanities and Social Sciences, National Science Council in Taiwan, were collected and analyzed. The analysis was done by structure of journal article and location of citations. In addition to citations appearing in the text, the phenomena of citation type will be compared and discussed in the latter part. The results of this study revealed articles of literature, history, philosophy and arts were mostly argumentative, while linguistic articles tended to comply with IMRAD (Introduction, Methods and Materials, Results,And Discussion formats. Introducing primary materials from original works, humanity scholars tended to cite for factual descriptions or to support authors’ perspectives. Secondary materials, such as later studies on the original works by other scholars, were seen the most in the disciplines of linguistics while the least in that of history. In general, the distribution of citation types is similar between articles in domestic and foreign journals; merely minor differences occurred among disciplines. While citing characteristics and information needs of humanities scholars revealed in this study may contribute to collection development of libraries or refinement of information services to researchers, suggestions based on analysis of research results may also serve as reference for standardization of writing and publication of journal articles in Taiwan. Aiming at further exploration of citations, this study is expected to provide a better understanding of the nature of citations and to serve as a foundation for future empirical studies.

  15. From Excessive Journal Self-Cites to Citation Stacking: Analysis of Journal Self-Citation Kinetics in Search for Journals, Which Boost Their Scientometric Indicators.

    Heneberg, Petr

    2016-01-01

    Bibliometric indicators increasingly affect careers, funding, and reputation of individuals, their institutions and journals themselves. In contrast to author self-citations, little is known about kinetics of journal self-citations. Here we hypothesized that they may show a generalizable pattern within particular research fields or across multiple fields. We thus analyzed self-cites to 60 journals from three research fields (multidisciplinary sciences, parasitology, and information science). We also hypothesized that the kinetics of journal self-citations and citations received from other journals of the same publisher may differ from foreign citations. We analyzed the journals published the American Association for the Advancement of Science, Nature Publishing Group, and Editura Academiei Române. We found that although the kinetics of journal self-cites is generally faster compared to foreign cites, it shows some field-specific characteristics.

    Full Text Available Bibliometric indicators increasingly affect careers, funding, and reputation of individuals, their institutions and journals themselves. In contrast to author self-citations, little is known about kinetics of journal self-citations. Here we hypothesized that they may show a generalizable pattern within particular research fields or across multiple fields. We thus analyzed self-cites to 60 journals from three research fields (multidisciplinary sciences, parasitology, and information science. We also hypothesized that the kinetics of journal self-citations and citations received from other journals of the same publisher may differ from foreign citations. We analyzed the journals published the American Association for the Advancement of Science, Nature Publishing Group, and Editura Academiei Române. We found that although the kinetics of journal self-cites is generally faster compared to foreign cites, it shows some field-specific characteristics. Particularly in information science journals, the initial increase in a share of journal self-citations during post-publication year 0 was completely absent.

    Resource of traditional Chinese medicine residue is an inevitable choice to form new industries characterized of modem, environmental protection and intensive in the Chinese medicine industry. Based on the analysis of source and the main chemical composition of the herb residue, and for the advantages of membrane science and technology used in the pharmaceutical industry, especially membrane separation technology used in improvement technical reserves of traditional extraction and separation process in the pharmaceutical industry, it is proposed that membrane science and technology is one of the most important choices in technological design of traditional Chinese medicine resource industrialization. Traditional Chinese medicine residue is a very complex material system in composition and character, and scientific and effective "separation" process is the key areas of technology to re-use it. Integrated process can improve the productivity of the target product, enhance the purity of the product in the separation process, and solve many tasks which conventional separation is difficult to achieve. As integrated separation technology has the advantages of simplified process and reduced consumption, which are in line with the trend of the modern pharmaceutical industry, the membrane separation technology can provide a broad platform for integrated process, and membrane separation technology with its integrated technology have broad application prospects in achieving resource and industrialization process of traditional Chinese medicine residue. We discuss the principles, methods and applications practice of effective component resources in herb residue using membrane separation and integrated technology, describe the extraction, separation, concentration and purification application of membrane technology in traditional Chinese medicine residue, and systematically discourse suitability and feasibility of membrane technology in the process of traditional Chinese

    The study on Traditional Chinese Medicine (TCM)by the technology and method of thermal science is a new cut-in point in interdisciplinary science, and its purpose is to study the tongue inspection in TCM from the view of the bio-heat transfer theory. In this paper human tongues were studied with the infrared thermal imaging technology. And the characteristic relationship between temperature distribution and age, tongue color as well as infrared thermal tongue image concerning the characteristic of viscera was analyzed by the experimental data,which confirms that the change in temperature distribution in different positions of the tongue is related to the diseases of different internal organs of the body. From a series of invasive experiments in animals, the blood perfusion rate was measured with the equipment of CBI-8000 Doppler Blood Flow Meter and MP-100 Physiologic Research System for the first time and the characteristic relationship curve between the temperature on the surface of the tongue and the blood perfusion rate was obtained. From the experiments the temperature on the surface of the tongue reflects objectively the tongue color which is influenced by the blood perfusion rate. This will help to develop some new cognition in the theory of TCM.

  1. A review on citation amnesia in depression and inflammation research.

    Science.gov (United States)

    Maes, Michael

    2015-01-01

    Once original scientific results are published the author has the "intellectual property" and may claim ownership. Discovery credit is one of the most important "rewards" for scientists and thus incorrect credits undermine the reward system of science. Scientists who publish should therefore give proper credit and acknowledge the primary sources. Failure to do so is regarded as "citation negligence", "the disregard syndrome", "citation amnesia", "plagiarism by omission", "bibliographic plagiarism" or "citation plagiarism", and may range from an unconscious or conscious "failure to credit a prior discoverer so as to give an improper impression of priority" to "the appropriation of another person's ideas or results without given proper credit". False discovery credit is considered to be "a menace to honest science", "a serious transgression" or "intellectual theft, be it intentional or not". This paper describes some examples of citation amnesia showing that scientists often fail to credit prior sources and give false discovery credit to other scientists. One example is the association between major depression and activated immuno-inflammatory pathways, a discovery by European groups and published in many papers since 1990. Now, 25 years later, it is commonplace that these theories are credited to secondary American sources whose work in "the last decade", did or did not examine these pathways in major depression. This gives an improper impression of priority of American-based scientists. Here it is proposed that this citation amnesia and plagiarism reinforced the wrong science and had negative effects on the development of immune-inflammatory biomarkers and new immune-related treatments for depression. It is concluded that journal editors should improve their citation standards to guarantee correct assignment of discovery credit for example by demanding a signed pledge from the authors that correct citations to the primary sources were made.

    The citation impact of Environment and Planning B can be visualized using its citation relations with journals in its environment as the links of a network. The size of the nodes is varied in correspondence to the relative citation impact in this environment. Additionally, one can correct for the effect of within-journal "self"-citations. The network can be partitioned and clustered using algorithms from social network analysis. After transposing the matrix in terms of rows and columns, the citing patterns can be mapped analogously. Citing patterns reflect the activity of the community of authors who publish in the journal, while being cited indicates reception. Environment and Planning B is cited across the interface between the social sciences and the natural sciences, but its authors cite almost exclusively from the domain of the Social Science Citation Index.

    Cited author searches were conducted in Nursing Citation Index to determine its utility in locating clinical studies that apply the conceptual frameworks of Dorothea Orem, Callista Roy, Martha Rogers, Betty Neuman, and Dorothy Johnson. Fully 75 percent of the relevant papers would have been missed by a conventional subject/textword search in the MEDLINE or CINAHL databases. Had Nursing Citation Index not been available, only 22 percent of relevant papers could have been retrieved by cited author searches of Social Science Citation Index. In summary, Nursing Citation Index provides an important indexing link between nursing theory and nursing research.

    International collaboration is becoming increasingly important for the advancement of science. To gain a more precise understanding of how factors such as international collaboration influence publication success, we divide publication success into two categories: journal placement and citation performance. Analyzing all papers published between 1996 and 2012 in eight disciplines, we find that those with more countries in their affiliations performed better in both categories. Furthermore, specific countries vary in their effects both individually and in combination. Finally, we look at the relationship between national output (in papers published) and input (in citations received) over the 17 years, expanding upon prior depictions by also plotting an expected proportion of citations based on Journal Placement. Discrepancies between this expectation and the realized proportion of citations illuminate trends in performance, such as the decline of the Global North in response to rapidly developing countries, especially China. Yet, most countries' show little to no discrepancy, meaning that, in most cases, citation proportion can be predicted by Journal Placement alone. This reveals an extreme asymmetry between the opinions of a few reviewers and the degree to which paper acceptance and citation rates influence career advancement.

    Background: Self-citation is one of the main challenges in the evaluation of researchers’ scientific output. This study aimed at comparing the institutional self-citation among the universities located in Northern Iran. Methods: This study was conducted as a scientometric study. Research population included all scientific productions of 16 Northern Iran Universities with at least 100 indexed documents indexed in the Web of Science (WoS) by 2 June 2015. The citation analysis section of WoS was used for data collection. SPSS was applied for data analysis. Study hypotheses were tested with two independent sample t-test and paired sample t-test. Results: Producing 16,399 papers, northern Iran universities had 5.33% of contribution in Iran’s scientific production. They received 84,058 citations with 17% and 12% of self-citations belonged to the non-medical and medical universities, respectively. Testing hypotheses revealed that increase in received citations significantly increases the rate of self-citation and increase in scientific production does not necessarily increase the rate of self-citation. Conclusion: The rate of self-citation in the studied universities was not relatively high. However, investigating into the factors affecting the rate of and motives for self-citation needs further research. PMID:28077903

    Full Text Available In this study, we used the citation data from four databases (THCI, ACI, WOS and Scopus and one social media, Mendeley, to examine the composite traces of humanities and social sciences scholars’ research outputs. Using the researchers of the Institute for Advanced Studies in Humanities and Social Sciences in National Taiwan University as subjects, this study compared how the scholars’ publications were cited in Taiwan’s and international academic journals as well as used in the social Web. It found that most of the subjects’ publications were in Chinese, and the impact of the publications was domestic rather than international. Taiwan’s citation databases, unsurprisingly, saw more citations to their research outputs. However, when only the English publications were observed, it was found that the citation performances in international databases and Mendeley were highly correlated. This suggests that Mendeley is a valid altmetric citation source for observing the international impact of Taiwan’s scholars. [Article content in Chinese

  13. A Large-Scale Analysis of Impact Factor Biased Journal Self-Citations.

    2016-01-01

    Based on three decades of citation data from across scientific fields of science, we study trends in impact factor biased self-citations of scholarly journals, using a purpose-built and easy to use citation based measure. Our measure is given by the ratio between i) the relative share of journal self-citations to papers published in the last two years, and ii) the relative share of journal self-citations to papers published in preceding years. A ratio higher than one suggests that a journal's impact factor is disproportionally affected (inflated) by self-citations. Using recently reported survey data, we show that there is a relation between high values of our proposed measure and coercive journal self-citation malpractices. We use our measure to perform a large-scale analysis of impact factor biased journal self-citations. Our main empirical result is, that the share of journals for which our measure has a (very) high value has remained stable between the 1980s and the early 2000s, but has since risen strongly in all fields of science. This time span corresponds well with the growing obsession with the impact factor as a journal evaluation measure over the last decade. Taken together, this suggests a trend of increasingly pervasive journal self-citation malpractices, with all due unwanted consequences such as inflated perceived importance of journals and biased journal rankings.

    2016-09-01

    Despite their recognized limitations, bibliometric assessments of scientific productivity have been widely adopted. We describe here an improved method to quantify the influence of a research article by making novel use of its co-citation network to field-normalize the number of citations it has received. Article citation rates are divided by an expected citation rate that is derived from performance of articles in the same field and benchmarked to a peer comparison group. The resulting Relative Citation Ratio is article level and field independent and provides an alternative to the invalid practice of using journal impact factors to identify influential papers. To illustrate one application of our method, we analyzed 88,835 articles published between 2003 and 2010 and found that the National Institutes of Health awardees who authored those papers occupy relatively stable positions of influence across all disciplines. We demonstrate that the values generated by this method strongly correlate with the opinions of subject matter experts in biomedical research and suggest that the same approach should be generally applicable to articles published in all areas of science. A beta version of iCite, our web tool for calculating Relative Citation Ratios of articles listed in PubMed, is available at https://icite.od.nih.gov.

  17. Characterizing and modeling citation dynamics.

    Full Text Available Citation distributions are crucial for the analysis and modeling of the activity of scientists. We investigated bibliometric data of papers published in journals of the American Physical Society, searching for the type of function which best describes the observed citation distributions. We used the goodness of fit with Kolmogorov-Smirnov statistics for three classes of functions: log-normal, simple power law and shifted power law. The shifted power law turns out to be the most reliable hypothesis for all citation networks we derived, which correspond to different time spans. We find that citation dynamics is characterized by bursts, usually occurring within a few years since publication of a paper, and the burst size spans several orders of magnitude. We also investigated the microscopic mechanisms for the evolution of citation networks, by proposing a linear preferential attachment with time dependent initial attractiveness. The model successfully reproduces the empirical citation distributions and accounts for the presence of citation bursts as well.

    Nobel Prizes are commonly seen to be among the most prestigious achievements of our times. Based on mining several million citations, we quantitatively analyze the processes driving paradigm shifts in science. We find that groundbreaking discoveries of Nobel Prize Laureates and other famous scientists are not only acknowledged by many citations of their landmark papers. Surprisingly, they also boost the citation rates of their previous publications. Given that innovations must outcompete the rich-gets-richer effect for scientific citations, it turns out that they can make their way only through citation cascades. A quantitative analysis reveals how and why they happen. Science appears to behave like a self-organized critical system, in which citation cascades of all sizes occur, from continuous scientific progress all the way up to scientific revolutions, which change the way we see our world. Measuring the “boosting effect” of landmark papers, our analysis reveals how new ideas and new players can make their way and finally triumph in a world dominated by established paradigms. The underlying “boost factor” is also useful to discover scientific breakthroughs and talents much earlier than through classical citation analysis, which by now has become a widespread method to measure scientific excellence, influencing scientific careers and the distribution of research funds. Our findings reveal patterns of collective social behavior, which are also interesting from an attention economics perspective. Understanding the origin of scientific authority may therefore ultimately help to explain how social influence comes about and why the value of goods depends so strongly on the attention they attract.

    The Korean journal published in English, Nuclear Engineering and Technology (here under NET) has been enlisted in the global citation database SCI E(Science Citation Index Expanded) of Thomson Reuters (past ISI), beginning with NET vol.39 No.1 (Feb. 2007). As of July 2009, the citation index of NET as reported by JCR (Journal Citation Report) based on the cumulative data from ISI (Institute for Scientific Information) reached to 0.991. This index ranks on 12{sup th} among the 33 journals in the area of nuclear science and technology in the science and technology covered by JCR, meaning fairly high impact factor. The following year 2010, however, witnessed the JCR figure dropping down to 0.465. The reason behind such drastic fall would be the decreased citation and in a lesser extent self-citation in 2010, in comparison with 2009, despite the increased number of paper publication. This study attempts to give an analysis as of the end of 2011 on the NET citation frequency in SCI Source Journal and the citation frequency by KAERI authors, together with the nationalities of NET authors and SCI journals that refer to NET most.

    2006-01-01

    Paleoclimate modelling is one of the core topics in the Past Global Changes project under the International Geosphere-Biosphere Programme and has received much attention worldwide in recent decades.Here we summarize the research on the Paleoclimate modeling, including the Holocene, Last Glacial Maximum, and pre-Quaternary climate intervals or events performed at the Institute of Atmospheric Physics under the Chinese Academy of Sciences (IAP/CAS) for over one decade. As an attempt to review these academic activities, we emphasize that vegetation and ocean feedbacks can amplify East Asian climate response to the Earth's orbital parameters and atmospheric CO2 concentration at the mid-Holocene. At the Last Glacial Maximum, additional cooling in interior China is caused by the feedback effects of East Asian vegetation and the ice sheet over the Tibetan Plateau, and the regional climate model RegCM2 generally reduces data-model discrepancies in East Asia. The simulated mid-Pliocene climate is characterized by warmer and drier conditions as well as significantly weakened summer and winter monsoon systems in interior China. On a tectonic timescale, both the Tibetan Plateau uplift and the Paratethys Sea retreat play important roles in the formation of East Asian monsoon-dominant environmental pattern during the Cenozoic.

In view of the observation by other workers of gamma and neutrons from electric storms, the present paper seeks physical causes of such variation in terms of meteorological conditions. Previous work on Abrikosov vortices (rotating strings of electron Cooper pairs responsible for Type-II superconductivity) and their possible availability in near or actual electric storm conditions is reviewed. This work suggests fusion may be found in certain standard open cells, but not where lack of meteorological availability or the use of closed cells prevents the Abrikosov vortices being available inside the apparatus. No general method of direct testing for Abrikosov vortices is known, so no opinion for or against these ideas is offered. Tests made at the Chinese Academy of Sciences for the presence of meteorological triggers (of any type) for fusion events are described. Both continuous and short-burst fusion are reported to occur if, and only if, the meteorological trigger-conditions are present. This is taken as being possibly the first observation of meteorological triggers for cold fusion and the first reported observation of continuous fusion from this source. Various possible causal mechanisms behind the detailed results are discussed. A future experimental program to confirm and further define these effects is outlined. No claim can yet be made for definite confirmation of the Abrikosov vortex hypothesis, or any other cold fusion trigger or reaction details.

    Using the InCites tool of Thomson Reuters, this study compares normalized citation impact values calculated for China, Japan, France, Germany, United States, and the UK throughout the time period from 1981 to 2010. The citation impact values are normalized to four subject areas: natural sciences; engineering and technology; medical and health sciences; and agricultural sciences. The results show an increasing trend in citation impact values for France, the UK and especially for Germany across the last thirty years in all subject areas. The citation impact of papers from China is still at a relatively low level (mostly below the world average), but the country follows an increasing trend line. The USA exhibits a relatively stable pattern of high citation impact values across the years. With small impact differences between the publication years, the US trend is increasing in engineering and technology but decreasing in medical and health sciences as well as in agricultural sciences. Similar to the USA, Japan f...

    As research in Earth Science becomes more data intensive, a critical requirement of data archives is that data needs to be easily discovered, accessed, and used. One approach to improving data discovery and access is through data citations coupled with Digital Object Identifiers (DOI). Beginning in 1998, the Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) has issued data product citations that have been accepted and used in AGU and other peer-reviewed journals. Citation elements established by the ORNL DAAC are similar to those used for journal articles (authors, titles, information to locate, and version), and beginning in 2007 included a DOI that is persistent, actionable, specific, and complete. The citation approach used at the DAAC also allows for referring to specific subsets of the data, by including within the citation the temporal and spatial portions of the data actually used. Citations allow others to find data and reproduce the results of the research article, and also use those data to test new hypotheses, design new sample collections, or construct or evaluate models. In addition to enhancing discovery and access of the data used in a research article, the citation gives credit to data generators, data centers and their funders, and, through citation indices, determine the scientific impact of a data set. The ORNL DAAC has developed a database that links research articles and their use of ORNL DAAC data products. The database allows determination of who, in which journal, and how the data have been used, in a manner analogous to author citation indices. The ORNL DAAC has been an initial contributor to the Thomson Reuters Data Citation Index. In addition, research data products deposited at the ORNL DAAC are linked using DOIs to relevant articles in Elsevier journals available on ScienceDirect. The ultimate goal of this implementation is that citations to data products become a routine part of the scientific process.

    Modeling distributions of citations to scientific papers is crucial for understanding how science develops. However, there is a considerable empirical controversy on which statistical model fits the citation distributions best. This paper is concerned with rigorous empirical detection of power-law behaviour in the distribution of citations received by the most highly cited scientific papers. We have used a large, novel data set on citations to scientific papers published between 1998 and 2002 drawn from Scopus. The power-law model is compared with a number of alternative models using a likelihood ratio test. We have found that the power-law hypothesis is rejected for around half of the Scopus fields of science. For these fields of science, the Yule, power-law with exponential cut-off and log-normal distributions seem to fit the data better than the pure power-law model. On the other hand, when the power-law hypothesis is not rejected, it is usually empirically indistinguishable from most of the alternative mo...

    Smith, Derek R

    2007-12-14

    Although their contribution may go unrecognised at the time, if journal citations are indeed the "currency" of science, then citation classics could justifiably be regarded as the "gold bullion". This article examines the 10 most highly-cited articles published by the New Zealand Medical Journal (NZMJ), as of August 2007. By topic, the top cited article described a study of risk factors for sudden infant death syndrome among New Zealand infants, while 3 of the remaining 9 articles focused on asthma. Most citation classics from the NZMJ were comparatively recent, with the top cited article being published in 1991, 7 having been published in the 1980s, and 2 in the 1970s. Overall, this study clearly demonstrates the international relevance of New Zealand medical researchers, and the significant global impact of their findings for human health.

  17. The Citation Field of Evolutionary Economics

    Dolfsma, Wilfred

    2010-01-01

    Evolutionary economics has developed into an academic field of its own, institutionalized around, amongst others, the Journal of Evolutionary Economics (JEE). This paper analyzes the way and extent to which evolutionary economics has become an interdisciplinary journal, as its aim was: a journal that is indispensable in the exchange of expert knowledge on topics and using approaches that relate naturally with it. Analyzing citation data for the relevant academic field for the Journal of Evolutionary Economics, we use insights from scientometrics and social network analysis to find that, indeed, the JEE is a central player in this interdisciplinary field aiming mostly at understanding technological and regional dynamics. It does not, however, link firmly with the natural sciences (including biology) nor to management sciences, entrepreneurship, and organization studies. Another journal that could be perceived to have evolutionary acumen, the Journal of Economic Issues, does relate to heterodox economics journa...

    Modeling distributions of citations to scientific papers is crucial for understanding how science develops. However, there is a considerable empirical controversy on which statistical model fits the citation distributions best. This paper is concerned with rigorous empirical detection of power-law behaviour in the distribution of citations received by the most highly cited scientific papers. We have used a large, novel data set on citations to scientific papers published between 1998 and 2002 drawn from Scopus. The power-law model is compared with a number of alternative models using a likelihood ratio test. We have found that the power-law hypothesis is rejected for around half of the Scopus fields of science. For these fields of science, the Yule, power-law with exponential cut-off and log-normal distributions seem to fit the data better than the pure power-law model. On the other hand, when the power-law hypothesis is not rejected, it is usually empirically indistinguishable from most of the alternative models. The pure power-law model seems to be the best model only for the most highly cited papers in "Physics and Astronomy". Overall, our results seem to support theories implying that the most highly cited scientific papers follow the Yule, power-law with exponential cut-off or log-normal distribution. Our findings suggest also that power laws in citation distributions, when present, account only for a very small fraction of the published papers (less than 1 % for most of science fields) and that the power-law scaling parameter (exponent) is substantially higher (from around 3.2 to around 4.7) than found in the older literature.

    Acta Dermatovenerologica Alpina, Pannonica et Adriatica is the leading journal in the field of dermatology and sexually transmitted infections in the region. Several important steps were taken during the last 20 years to improve the journal's quality, global visibility, and international impact. Since 1992, 699 bibliographical items have been published, which received 1,360 citations. Web of Science citable items received on average 2.29 citations per item. Importantly, almost half (49.6%) of all citations retrieved to date were received from 2012 onwards. The predicted impact factor was calculated in a way to match official impact factors published annually in Thomson Scientific Journal Citation Reports. Citation analysis shows a substantial increase of the predicted impact factor since 2006, with values above 0.5 since 2007. For the first time in the journal's history, a predicted impact factor value above 1.0 was recorded in 2013.

    2011-01-01

    Using the Arts & Humanities Citation Index (AHCI) 2008, we apply mapping techniques previously developed for mapping journal structures in the Science and Social Science Citation Indices. Can a cognitive structure be reconstructed from the aggregated citation patterns among these 1,157 journals containing 110,718 records? Both cosine-normalization (bottom up) and factor analysis (top down) suggest a division into approximately twelve subsets. The relations among these subsets are shown using various visualization techniques. However, this structure could not be retrieved using the ISI Subject Categories, including the 25 categories which are specific to the AHCI. We discuss validation against the categories of the Humanities Indicators (of the American Academy of Arts and Sciences) and compare our results with the curriculum organization of the Humanities Section of the College of Letters and Sciences of UCLA (as an example).

    The view of science in the 20th century is reviewed. The impact of changes of science view in the 20th century on traditional Chinese medicine is clarified. The impact of positivist view of science on traditional Chinese medicine continued from the early 20th century to the present. Within a certain range, positivist view of science has its positive significance. The impact of science view of historicism on traditional Chinese medicine reflects in the application of system science on traditional Chinese medicine. Science view of historicism features of tolerance of different cultures which makes traditional Chinese medicine develop on the base of Chinese culture, different from unilateral emphasis on science in the past. The study on traditional Chinese medicine which is characterized by developing on the base of basic theory of traditional Chinese medicine becomes more and more popular, being an important direction of study on modern study of traditional Chinese medicine.%回顾近现代中国科学观的变迁,阐明近现代科学观的变迁对中医发展的影响.实证主义科学观对中医发展的影响从20世纪初持续到现在,在一定范围内有其积极意义.历史主义科学观对现代中医的影响体现为以系统科学分析研究中医.历史主义科学观对不同文化间的包容使得中医的生存有了传统文化的土壤,而不是像以前一样单方面强调科学的影响.以坚持中医基本理论为发展基石的中医研究逐渐壮大,正成为当代中医研究的一个重要研究方向.

    Institute of Scientific and Technical Information of China (English)

    杜冰茜

    2015-01-01

    Arguably, novice writers were warned of using “I”,“we”, or equivalents in an academic essay of hard sciences to“pretend to a scientific scholarly style”(Spack, 1988, p.39), although the issue of impersonality and its interdisciplinary variations have been documented in the research literature (Hyland, 2002). Now, it was partially acknowledged that authors were omniscient, as captured by Ivanic? & Camps (2001): “There is no such thing as ‘impersonal' writing…”. (p.5) However, as self-mention was obviously subjective, it followed that natural science RAs should be more objective to include few “I”s or “we”s. To attest to this belief, this paper investigated whether there were self-mentions in 4 published works (of renown journals) written by Chinese scholars from the Chemistry Department.

    2011-12-01

    Full Text Available The h-index is one of the recent indicators in the field of scientometric which introduced by Jorge Hirsch and measures both the productivity and impact of scholars' work. It has been widely used to show the relevance of the research work of prominent scholars. But, does h-index really show this relevance? The purpose of this study is to investigate the frequency of citations to highly-cited researchers by their co-authors, as well as to quantify the weight of self-citations of highly-cited researchers' in three fields of science: clinical medicine, computer science, and economics & business. Finally, we seek to evaluate the impact of these two elements on their h-index in the Scopus database. In this research, highly-cited researchers were selected from the three fields via HighlyCited.com. The study population includes 999 highly-cited researchers in these three fields (280 authors in clinical medicine, 373 authors in computer science, and 346 authors in economics & business. The results show that the average rate of self-citations and co-author citations in clinical medicine is more than computer science, and in computer science is more than economics & business. The results show that there is a positive correlation between self-citation and total citations (P<0.01 in these three fields. The results also show that there is a positive correlation between "co-author citations" and total citations (P<0.01. Moreover, there is a positive correlation between self-citations and h-index of highly-cited researchers as well as co-author citations and h-index of highly-cited researchers in the above-mentioned three fields. It is seen that there is a significant difference in self-citations behavior and co-author citation behavior in different fields which relates to subject context. Co-author citation is an indicator which, on the one hand, not under control of own researcher and, on the other hand, represents the structure of scientific communications

    Recent science of science research shows that scientific impact measures for journals and individual articles have quantifiable regularities across both time and discipline. However, little is known about the scientific impact distribution at the scale of an individual scientist. We analyze the aggregate production and impact using the rank-citation profile ci(r) of 200 distinguished professors and 100 assistant professors. For the entire range of paper rank r, we fit each ci(r) to a common distribution function. Since two scientists with equivalent Hirsch h-index can have significantly different ci(r) profiles, our results demonstrate the utility of the βi scaling parameter in conjunction with hi for quantifying individual publication impact. We show that the total number of citations Ci tallied from a scientist's Ni papers scales as . Such statistical regularities in the input-output patterns of scientists can be used as benchmarks for theoretical models of career progress.

  7. Exploiting citation networks for large-scale author name disambiguation

    CERN Document Server

    Schulz, Christian; Petersen, Alexander M; Penner, Orion; Helbing, Dirk

    2014-01-01

    We present a novel algorithm and validation method for disambiguating author names in very large bibliographic data sets and apply it to the full Web of Science (WoS) citation index. Our algorithm relies only upon on the author and citation graphs available for the whole period covered by the WoS. A pair-wise publication similarity metric, which is based on common co-authors, self-citations, shared references and citations, is established to perform a two-step agglomerative clustering that first connects linked papers and then merges similar clusters. This parameterized model is optimized towards an h-index based recall, which favors the inclusion of well-cited publications, and a name-initials-based precision using WoS metadata and cross-referenced Google Scholar profiles. Despite the use of limited metadata, we reach a recall of 87% and a precision of 88% with a preference for researchers with high $h$-index values. 47 million articles of WoS can be disambiguated on a single machine in less than a day. We d...

  8. Citation analysis of the Croatian Medical Journal: the first 15 years.

    Science.gov (United States)

    Kovacić, Natasa; Huić, Mirjana; Ivanis, Ana

    2008-02-01

    The Croatian Medical Journal (CMJ) is a bimonthly scientific journal, that publishes mostly original articles. It is indexed in the Index Medicus/MEDLINE, Current Contents/Clinical Medicine, and the Science Citation Index Expanded. Since the CMJ's 15th anniversary in 2007, our aim has been to assess the importance of the Journal through its impact factor (IF) and immediacy index, with a particular focus placed on the proportion of self-citations. According the Web of Knowledge database, the current official IF for the CMJ is 0.825, ranking it 62nd out of 103 journals within the Thomson Scientific category "Medicine - General and Internal." The exclusion of self-citations resulted in a small decrease in the journal's rank - to 66th place. According to the Web of Science database, the predicted CMJ IF in 2007 is between 1.024 and 1.125, showing a clear increase. The immediacy index of the CMJ is continuously low, with a high contribution of self-citations, implying that articles published in the CMJ require more time to be cited, and that their topics are of particular interest to the journal's readers and contributors. Self-citations contributed significantly to the IF in the first few years after the journal was established. The proportion of independent citations progressively increased, and of all the citations included in the IF in 2007, almost 70% were fully independent. Some of these citations were from articles published in journals with IF higher than 5. Taken together, our data suggest that the CMJ has significantly improved its citation ratings during the last 15 years, confirming that a quality-oriented editorial policy in a small peripheral journal may result in a truly increased international visibility.

    Background Citation analysis has become an important tool for research performance assessment in the medical sciences. However, different areas of medical research may have considerably different citation practices, even within the same medical field. Because of this, it is unclear to what extent citation-based bibliometric indicators allow for valid comparisons between research units active in different areas of medical research. Methodology A visualization methodology is introduced that reveals differences in citation practices between medical research areas. The methodology extracts terms from the titles and abstracts of a large collection of publications and uses these terms to visualize the structure of a medical field and to indicate how research areas within this field differ from each other in their average citation impact. Results Visualizations are provided for 32 medical fields, defined based on journal subject categories in the Web of Science database. The analysis focuses on three fields: Cardiac & cardiovascular systems, Clinical neurology, and Surgery. In each of these fields, there turn out to be large differences in citation practices between research areas. Low-impact research areas tend to focus on clinical intervention research, while high-impact research areas are often more oriented on basic and diagnostic research. Conclusions Popular bibliometric indicators, such as the h-index and the impact factor, do not correct for differences in citation practices between medical fields. These indicators therefore cannot be used to make accurate between-field comparisons. More sophisticated bibliometric indicators do correct for field differences but still fail to take into account within-field heterogeneity in citation practices. As a consequence, the citation impact of clinical intervention research may be substantially underestimated in comparison with basic and diagnostic research. PMID:23638064

  11. A reverse engineering approach to the suppression of citation biases reveals universal properties of citation distributions

    Radicchi, Filippo; 10.1371/journal.pone.0033833

    2012-01-01

    The large amount of information contained in bibliographic databases has recently boosted the use of citations, and other indicators based on citation numbers, as tools for the quantitative assessment of scientific research. Citations counts are often interpreted as proxies for the scientific influence of papers, journals, scholars, and institutions. However, a rigorous and scientifically grounded methodology for a correct use of citation counts is still missing. In particular, cross-disciplinary comparisons in terms of raw citation counts systematically favors scientific disciplines with higher citation and publication rates. Here we perform an exhaustive study of the citation patterns of millions of papers, and derive a simple transformation of citation counts able to suppress the disproportionate citation counts among scientific domains. We find that the transformation is well described by a power-law function, and that the parameter values of the transformation are typical features of each scientific disc...

    2007-01-01

    Objectives: to verify the feasibility and reliability of the electronic version of Chinese SF-36 based on the Quality-of-Life-Recorder. Design: A crossover randomized controlled trial, comparing a paper-based and an electronic version of the Chinese SF-36, was conducted. According to generated random numbers, interviewees were asked to fill out either the electronic version or the paper version first. The second version was filled in after a pause of at least 10 min. Settings and participants: One group of 100 medical students at the School of Medicine of Zhejiang University and the other group of 50 outpatients at a clinic for general practice in Hangzhou City (China) were eventually recruited in this study. Results: The acceptance of the electronic version was good (60% of medical students and 84% of outpatients preferred the electronic version). At the level of eight-scale scores, the mean-difference for each scale (except for general health) between the two versions was less than 5%. At the level of 36 questions, the percentage of "exact agreement" ranged within 64%~99%; the percentage of "global agreement" ranged within 72%~99%; 77% of the kappa coefficients demonstrated "good/excellent agreement" and 23% of the kappa coefficients demonstrated "medium agreement". Conclusion: This study, for the first time, can provide empirical basis for the confirmation of the feasibility and reliability of the electronic version of the Chinese SF-36 and may provide an impulse towards widespread deployment of the Quality-of-Life-Recorder in Chinese populations.

    Currently green IT has been a hotspot in both practice and research fields. Much progress has been made in the aspect of green technologies. However, researchers and designers could not simply build up a green IT system from technological aspect, which is normally considered as a wicked problem. This paper puts forward a research methodology for green IT systems by introducing WSR and design science. This methodology absorbs essence from soft systems methodology and action research. It considers the research, design and building of green IT systems from a systemic perspective which can be divided into as technological dimension, management dimension and human dimension. This methodology consists of 7 iterated stages. Each stage is presented and followed by a case study from a Chinese company.

    AIM:To analyze the literature on the use of Chinese herbal medicines for the treatment of cholecystitis.METHODS:The literature on treatment of cholecystitis with traditional Chinese medicines (TCM) was analyzed based on the principles and methods described by evidence-based medicine (EBM).Eight databases including MEDLINE,EMbase,Cochrane Central (CCTR),four Chinese databases (China Biological Medicine Database,Chinese National Knowledge Infrastructure Database,Database of Chinese Science and Technology Periodicals,Database of Chinese Ministry of Science and Technology) and Chinese Clinical Registry Center,were searched.Full text articles or abstracts concerning TCM treatment of cholecystitis were selected,categorized according to study design,the strength of evidence,the first author's hospital type,and analyzed statistically.RESULTS:A search of the literature published from 1977 through 2009 yielded 1468 articles in Chinese and 9 in other languages; and 93.92% of the articles focused on clinical studies.No article was of level I evidence,and 9.26% were of level Ⅱ evidence.The literature cited by Science Citation Index (SCI),MEDLINE and core Chinese medical journals accounted for 0.41%,0.68% and 7.29%,respectively.Typically,the articles featured in case reports of illness,examined from the perspective of EBM,were weak in both quality and evidence level,which inconsistently conflicted with the fact that most of the papers were by authors from Level-3 hospitals,the highest possible level evaluated based on their comprehensive quality and academic authenticity in China.CONCLUSION:The published literature on TCM treatment of cholecystitis is of low quality and based on low evidence,and cognitive medicine may functions as a useful supplementary framework for the evaluation.

  18. Measuring contextual citation impact of scientific journals

    Moed, Henk F

    2009-01-01

    This paper explores a new indicator of journal citation impact, denoted as source normalized impact per paper (SNIP). It measures a journal's contextual citation impact, taking into account characteristics of its properly defined subject field, especially the frequency at which authors cite other papers in their reference lists, the rapidity of maturing of citation impact, and the extent to which a database used for the assessment covers the field's literature. It further develops Eugene Garfield's notions of a field's 'citation potential' defined as the average length of references lists in a field and determining the probability of being cited, and the need in fair performance assessments to correct for differences between subject fields. A journal's subject field is defined as the set of papers citing that journal. SNIP is defined as the ratio of the journal's citation count per paper and the citation potential in its subject field. It aims to allow direct comparison of sources in different subject fields....

    2010-06-01

    We describe the ongoing citations to biomedical articles affected by scientific misconduct, and characterize the papers that cite these affected articles. The citations to 102 articles named in official findings of scientific misconduct during the period of 1993 and 2001 were identified through the Institute for Scientific Information Web of Science database. Using a stratified random sampling strategy, we performed a content analysis of 603 of the 5,393 citing papers to identify indications of awareness that the cited articles affected by scientific misconduct had validity issues, and to examine how the citing papers referred to the affected articles. Fewer than 5% of citing papers indicated any awareness that the cited article was retracted or named in a finding of misconduct. We also tested the hypothesis that affected articles would have fewer citations than a comparison sample; this was not supported. Most articles affected by misconduct were published in basic science journals, and we found little cause for concern that such articles may have affected clinical equipoise or clinical care.

    2013-01-01

    In this paper we provide the reader with a visual representation of relationships among the impact of book chapters indexed in the Book Citation Index using information gain values and published by different academic publishers in specific disciplines. The impact of book chapters can be characterized statistically by citations histograms. For instance, we can compute the probability of occurrence of book chapters with a number of citations in different intervals for each academic publisher. We predict the similarity between two citation histograms based on the amount of relative information between such characterizations. We observe that the citation patterns of book chapters follow a Lotkaian distribution. This paper describes the structure of the Book Citation Index using 'heliocentric clockwise maps' which allow the reader not only to determine the grade of similarity of a given academic publisher indexed in the Book Citation Index with a specific discipline according to their citation distribution, but al...

However, citation distributions are skewed, and the average has the disadvantage that the number of publications is used in the denominator. Using hundred percentiles, one can integrate the normalized citation curve and develop an indicator that can be compared across document sets because percentile ranks are defined at the article level. I apply this indicator to the set of 58 journals in the ISI Subject Category of "Nanoscience & nanotechnology," and rank journals, countries, cities, and institutes using non-parametric statistics.

  4. Bibliometrics as weapons of mass citation.

    Science.gov (United States)

    Molinié, Antoinette; Bodenhausen, Geoffrey

    2010-01-01

    The allocation of resources for research is increasingly based on so-called 'bibliometrics'. Scientists are now deemed to be successful on the sole condition that their work be abundantly cited. This world-wide trend appears to enjoy support not only by granting agencies (whose task is obviously simplified by extensive recourse to bibliometrics), but also by the scientists themselves (who seem to enjoy their status of celebrities). This trend appears to be fraught with dangers, particularly in the area of social sciences, where bibliometrics are less developed, and where monographs (which are not taken into account in citation indexes) are often more important than articles published in journals. We argue in favour of a return to the values of 'real science', in analogy to the much-promised return to a 'real economy'. While economists may strive towards a more objective evaluation of the prospects of a company, a market, or an industrial sector, we scientists can only base our appraisal on a responsible practice of peer review. Since we fear that decision-takers of granting agencies such as the FNRS, CTI, EPFL, ETHZ, ANR, CNRS, NIH, NSF, DOE, etc. will be too busy to read our humble paper in Chimia, we appeal to scientists of all countries and disciplines to unite against the tyranny of bibliometrics.

    2015-01-01

    Modern bibliographic databases provide the basis for scientific research and its evaluation. While their content and structure differ substantially, there exist only informal notions on their reliability. Here we compare the topological consistency of citation networks extracted from six popular bibliographic databases including Web of Science, CiteSeer and arXiv.org. The networks are assessed through a rich set of local and global graph statistics. We first reveal statistically significant inconsistencies between some of the databases with respect to individual statistics. For example, the introduced field bow-tie decomposition of DBLP Computer Science Bibliography substantially differs from the rest due to the coverage of the database, while the citation information within arXiv.org is the most exhaustive. Finally, we compare the databases over multiple graph statistics using the critical difference diagram. The citation topology of DBLP Computer Science Bibliography is the least consistent with the rest, w...

    Self-references, self-citations are considered by some as the sign of vanity, and deemed to be omitted from scientometrics analyses. In fact, self-citations reveal information in the study of scientific communications that is different but not less valuable than citations received from others. In the practice of self-citation severe ethical issues may emerge that can be bandled by the co-operation of the authors, editors and publishers. Orv. Hetil., 2016, 157(32), 1289-1293.

    2014-10-01

    Memes are the cultural equivalent of genes that spread across human culture by means of imitation. What makes a meme and what distinguishes it from other forms of information, however, is still poorly understood. Our analysis of memes in the scientific literature reveals that they are governed by a surprisingly simple relationship between frequency of occurrence and the degree to which they propagate along the citation graph. We propose a simple formalization of this pattern and validate it with data from close to 50 million publication records from the Web of Science, PubMed Central, and the American Physical Society. Evaluations relying on human annotators, citation network randomizations, and comparisons with several alternative approaches confirm that our formula is accurate and effective, without a dependence on linguistic or ontological knowledge and without the application of arbitrary thresholds or filters.

    With the arrival of the information age,research activities focused on the practice and approaches of knowledge services are on a marked increase as evidenced in the publications of social sciences.According to a social network analysis on knowledge service related literature,it reveals that information and knowledge workers often fail to take such an important element as the functional role of an emotive engagement into consideration in their study of knowledge services.It has increasingly become an issue of high profile with the rapid development of digital libraries and their web-based knowledge services in China and anywhere else in the world.In order to have a clearer understanding about issues involved in knowledge servicing so as to maximize the effectiveness and efficiency of digital libraries in their knowledge service performance,the author has conducted surveys for seven times on the online information seeking behavior of graduate students at the Chinese Academy of Sciences with such research methods as questionnaires,interviews and natural observations during September 2006-June 2009.The research result has showed the emotive element has an important role in the user’s information seeking behavior and in knowledge services practice.Therefore,knowledge services rendered may be more effective by adding the emotiveness-oriented communication element into such practice.This paper recommends that such an emotiveness-oriented communication approach should be carefully studied and factored into libraries’knowledge services practice.

    The complex science is the science of the 21st century,is one of the world's most complicated systems. Traditional Chinese medicine,truthfully contacted and realized the complex of the human health and diseases,has becoming the pioneer of complex research,the first complex science. The essence of com-plex of was "super reduction" which deviated from the reduction study in modern medicine and becoming the watershed between Chinese medicine and western medicine. The typical examples of the complex of health and disease in TCM included:openness and holism of human communicating and corresponding to the universe,the more complex life structure than human body,life movement contributing to body structure, dynamic disorder as "syndrome","unpurified" pathogenesis,self organization and autonomy,prescription mak-ing the herbal feature and effect complex.%复杂性科学是21世纪的科学,人是世界上最复杂的系统,中医原原本本地接触和认识了人的健康与疾病的复杂性,成为复杂性研究的先驱,是第一门复杂性科学.复杂性的本质特征是"超还原",西医近代以来的还原研究背离了复杂性,复杂性成为中西医学术的分水岭.中医所认识的健康与疾病的复杂性,最为典型的有:生气通天的开放性、"涌现"出来的整体性、比人体更复杂的生命运动结构、人体的结构由生命运动赋型、生命运动态的失常为"证"、不可"提纯"的病机、人的自组织与自主性、方剂把药性和药效复杂化.

  12. Can Scientific Journals be Classified in terms of Aggregated Journal-Journal Citation Relations using the Journal Citation Reports?

    CERN Document Server

    Leydesdorff, Loet

    2009-01-01

    The aggregated citation relations among journals included in the Science Citation Index provide us with a huge matrix which can be analyzed in various ways. Using principal component analysis or factor analysis, the factor scores can be used as indicators of the position of the cited journals in the citing dimensions of the database. Unrotated factor scores are exact, and the extraction of principal components can be made stepwise since the principal components are independent. Rotation may be needed for the designation, but in the rotated solution a model is assumed. This assumption can be legitimated on pragmatic or theoretical grounds. Since the resulting outcomes remain sensitive to the assumptions in the model, an unambiguous classification is no longer possible in this case. However, the factor-analytic solutions allow us to test classifications against the structures contained in the database. This will be demonstrated for the delineation of a set of biochemistry journals.

    The Marine Biological Laboratory/Woods Hole Oceanographic Institution (MBLWHOI) Library, the Scientific Committee on Oceanic Research (SCOR) and the International Oceanographic Data and Information Exchange (IODE) of the Intergovernmental Oceanographic Commission have assembled a team of librarians, data managers and scientists who are collaborating to identify best practices for tracking data provenance and clearly attributing credit to data collectors/providers. One successful outcome of this collaborative effort includes tools and procedures developed by the Marine Biological Laboratory/Woods Hole Oceanographic Institution (MBLWHOI) Library and the Biological and Chemical Oceanography Data Management Office (BCO-DMO) that automate the ingestion of metadata from BCO-DMO for deposit with a copy of each data set into the Institutional Repository (IR) Woods Hole Open Access Server (WHOAS). The system also incorporates functionality for BCO-DMO to request a Digital Object Identifier (DOI) from the Library. This partnership allows the Library to work with a trusted data repository to ensure high quality data while the data repository utilizes library services and is assured that a permanent archived copy of the data is associated with the persistent DOI. The assignment of persistent identifiers enables accurate data citation. The Library can assign a DOI to appropriate datasets deposited in WHOAS. We are particularly interested in working with authors to deposit datasets associated with published articles. The DOI would ideally be assigned before submission and be included in the published paper so readers can link directly to the dataset, but DOIs are also being assigned to datasets that support papers that have already been published. WHOAS metadata records link the article to the datasets and the datasets to the article. Because of the assignment of DOIs, Elsevier Publishing sought a collaboration with the Library. Article records in Science Direct now contain

    ; they also verified that the journals were using the APC model by visiting each journal’s website. Because of the large number of subject areas of the identified journals, the researchers decided to classify the journals into four broader categories: Health Sciences, Life Sciences, Natural Sciences, and Social Sciences and Humanities. To calculate the impact of OA papers, citation per paper (CPP was calculated for each subject area. Impact values were calculated on an annual basis as well. The researchers calculated the citation advantage of OA articles as the “difference between the open access and toll access impacts in terms of a percentage of the latter” (p. 585. Main Results – The authors categorized their findings according to three themes: the growth of APC funded OA papers, the number of OA papers by discipline, and citation advantage of OA vs. TA in general and by subject area. Together, Springer and Elsevier published 18,654 OA papers in the APC journals; this number represents 4.7% of the 396,760 papers published between 2007 and 2011. While the number of OA and TA papers has been growing annually, the number of OA papers has been growing more rapidly compared to the TA papers. In terms of subject areas, Life Sciences had the largest number of OA and TA papers (184,315, followed by Health Sciences (149,341, Natural Sciences (121,274, and Social Sciences and Humanities (42,824. Natural Sciences had the most OA papers (5.7% in terms of the number of papers in this subject area being OA papers, followed by Social Sciences and Humanities (5.2%, Health Sciences (4.6% and Life Sciences (3.6%. Overall, the researchers found that the impact values of OA papers were larger than those of the TA papers for each year examined. In considering subject areas, in all disciplines except Life Sciences, the most highly cited paper in the field is an OA paper. In Life Sciences, the most highly cited TA paper had 2,215 citations, compared to the OA paper, which had 1

    2010-01-01

    Invenio is the web-based integrated digital library system developed at CERN. Within this framework, we present four types of ranking models based on the citation graph that complement the simple approach based on citation counts: time-dependent citation counts, a relevancy ranking which extends the PageRank model, a time-dependent ranking which combines the freshness of citations with PageRank and a ranking that takes into consideration the external citations. We present our analysis and results obtained on two main data sets: Inspire and CERN Document Server. Our main contributions are: (i) a study of the currently available ranking methods based on the citation graph; (ii) the development of new ranking methods that correct some of the identified limitations of the current methods such as treating all citations of equal importance, not taking time into account or considering the citation graph complete; (iii) a detailed study of the key parameters for these ranking methods.

  19. Citation score normalized by cited references (CSNCR): The introduction of a new citation impact indicator

    CERN Document Server

    Bornmann, Lutz

    2016-01-01

    In this paper, a new field-normalized indicator is introduced, which is rooted in early insights in bibliometrics, and is compared with several established field-normalized indicators (e.g. the mean normalized citation score, MNCS, and indicators based on percentile approaches). Garfield (1979) emphasizes that bare citation counts from different fields cannot be compared for evaluative purposes, because the "citation potential" can vary significantly between the fields. Garfield (1979) suggests that "the most accurate measure of citation potential is the average number of references per paper published in a given field". Based on this suggestion, the new indicator is basically defined as follows: the citation count of a focal paper is divided by the mean number of cited references in a field to normalize citations. The new indicator is called citation score normalized by cited references (CSNCR). The theoretical analysis of the CSNCR shows that it has the properties of consistency and homogeneous normalizatio...

    Data from open access biomolecular data resources, such as the European Nucleotide Archive and the Protein Data Bank are extensively reused within life science research for comparative studies, method development and to derive new scientific insights. Indicators that estimate the extent and utility of such secondary use of research data need to reflect this complex and highly variable data usage. By linking open access scientific literature, via Europe PubMedCentral, to the metadata in biological data resources we separate data citations associated with a deposition statement from citations that capture the subsequent, long-term, reuse of data in academia and industry.  We extend this analysis to begin to investigate citations of biomolecular resources in patent documents. We find citations in more than 8,000 patents from 2014, demonstrating substantial use and an important role for data resources in defining biological concepts in granted patents to both academic and industrial innovators. Combined together our results indicate that the citation patterns in biomedical literature and patents vary, not only due to citation practice but also according to the data resource cited. The results guard against the use of simple metrics such as citation counts and show that indicators of data use must not only take into account citations within the biomedical literature but also include reuse of data in industry and other parts of society by including patents and other scientific and technical documents such as guidelines, reports and grant applications.

    CERN Document Server

    2011-01-01

    Is there a difference in citation rates between articles that were published with links to data and articles that were not? Besides being interesting from a purely academic point of view, this question is also highly relevant for the process of furthering science. Data sharing not only helps the process of verification of claims, but also the discovery of new findings in archival data. However, linking to data still is a far cry away from being a "practice", especially where it comes to authors providing these links during the writing and submission process. You need to have both a willingness and a publication mechanism in order to create such a practice. Showing that articles with links to data get higher citation rates might increase the willingness of scientists to take the extra steps of linking data sources to their publications. In this presentation we will show this is indeed the case: articles with links to data result in higher citation rates than articles without such links. The ADS is funded by NA...

  12. Bibliometric Approach to Research Assessment: Publication Count, Citation Count, & Author Rank

    Directory of Open Access Journals (Sweden)

    Yang, Kiduk

    2013-03-01

    Full Text Available We investigated how bibliometric indicators such as publication count and citation count affect the assessment of research performance by computing various bibliometric scores of the works of Korean LIS faculty members and comparing the rankings by those scores. For the study data, we used the publication and citation data of 159 tenure-track faculty members of Library and Information Science departments in 34 Korean universities. The study results showed correlation between publication count and citation count for authors with many publications but the opposite evidence for authors with few publications. The study results suggest that as authors publish more and more work, citations to their work tend to increase along with publication count. However, for junior faculty members who have not yet accumulated enough publications, citations to their work are of great importance in assessing their research performance. The study data also showed that there are marked differences in the magnitude of citations between papers published in Korean journals and papers published in international journals.

    Full Text Available The Animals in Research: Reporting In Vivo Experiments (ARRIVE guidelines were published in 2010 with the aim of improving the quality of studies involving animals. However, how well Chinese studies involving animal neoplasms adhere to these guidelines has not been assessed.To evaluate the reporting quality of such experiments published between 2010 and 2012 in Chinese journals with support from the National Natural Science Foundation of China.We searched the Chinese Science Citation and Chinese Journal Full-Text Databases for articles published between 2010 and 2012 involving neoplasms in animals. The data were extracted into pre-prepared forms. Reporting quality was assessed using the ARRIVE checklist-39 items plus information on blinding.Three hundred and ninety-six animal studies were included in the analysis: 127 studies published in 2010, 140 studies published in 2011, and 129 studies published in 2012. The range of ARRIVE score is from 12 to 27 with a maximum possible score of 40. Studies published in 2012 (P = 0.012, 2011 (P = 0.015, 2010, July~Dec (P<0.017 had a significantly larger ARRIVE checklist score than those published in Jan.~June, 2010, respectively.Experiments involving neoplasms in animals published in Chinese journals generally have not comprehensively reported the information recommended by the ARRIVE guidelines. We strongly recommend that researchers conducting such studies report this information.

  16. Citation impacts revisited: how novel impact measures reflect interdisciplinarity and structural change at the local and global level

    CERN Document Server

    Zitt, Michel

    2013-01-01

    Citation networks have fed numerous works in scientific evaluation, science mapping (and more recently large-scale network studies) for decades. The variety of citation behavior across scientific fields is both a research topic in sociology of science, and a problem in scientific evaluation. Normalization, tantamount to a particular weighting of links in the citation network, is necessary for allowing across-field comparisons of citation scores and interdisciplinary studies. In addition to classical normalization which drastically reduces all variability factors altogether, two tracks of research have emerged in the recent years. One is the revival of iterative "influence measures". The second is the "citing-side" normalization, whose only purpose is to control for the main factor of variability, the inequality in citing propensity, letting other aspects play: knowledge export/imports and growth. When all variables are defined at the same field-level, two propositions are established: (a) the gross impact mea...

    BACKGROUND: Neural regeneration fol owing nerve injury is an emerging field that attracts ex-tending interests al over the world. OBJECTIVE: To use bibliometric indexes to track studies focusing on neural regeneration, and to investigate the relationships among geographic origin, countries and institutes, keywords in the published articles, and especial y focus on the region distribution, institution distribution, as wel as col aborations in Chinese papers indexed in the Web of Science. METHODS: A list of neural regeneration studies was generated by searching the database of the Web of Science-Expanded using the term“Neural Regenera*”. Inclusive criteria:(1) articles in the field of neural regeneration;(2) fundamental research on animals, clinical trials and case reports;(3) article types: article, review, proceedings paper, note, letter, editorial material, discussion, book chapter; (4) year of publication: 2003-2012; and (5) citation database: Science Citation In-dex-Expanded. Exclusive criteria: (1) articles requiring manual searching or with access only by telephone;(2) unpublished articles;and (3) corrections. RESULTS:A total of 4 893 papers were retrieved from the Web of Science published between 2003 and 2012. The papers covered 65 countries or regions, of which the United States ranked first with 1 691 papers. The most relevant papers were in the neurosciences and cellbiology, and the key-word “stem cel” was the most frequent. In recent years, China showed a great increase in the number of papers. Over the entire 10 years, there were 922 Chinese papers, with Jilin University ranking first with 58 articles. Chinese papers were published in connection with many countries, in-cluding the United States, Japan, and the United Kingdom. Among the connections, the papers published by the Chinese and the American are 107, with the highest rate.

    2012-10-01

    From citation rates for over 85,000 articles published between 1950 and 2004 in 56 psychology journals, we identified a total of 500 behavioral cognitive psychology articles that ranked in the top 0.6% in each half-decade, in terms of their mean citations per year using the Web of Science. Thirty nine percent [corrected] of these articles were produced by 78 authors who authored three or more of them, and more than half were published by only five journals.The mean number of cites per year and the total number of citations necessary for an article to achieve various percentile rankings are reported for each journal. The mean number of citations necessary for an article published within each half-decade to rank at any given percentile has steadily increased from 1950 to 2004. Of the articles that we surveyed, 11% had zero total citations, and 35% received fewer than four total citations. Citations for post-1994 articles ranking in the 50th-75th and 90th-95th percentiles have generally continued to grow across each of their 3-year postpublication bins. For pre-1995 articles ranking in the 50th-75th and 90th-95th percentiles, citations peaked in the 4- to 6- or 7- to 9-year postpublication bins and decreased linearly thereafter, until asymptoting. In contrast, for the top-500 articles, (a) for pre-1980 articles, citations grew and peaked 10-18-year postpublication bins, and after a slight decrease began to linearly increase again; (b) for post-1979 articles, citations have continually increased across years in a nearly linear fashion. We also report changes in topics covered by the top-cited articles over the decades.

  5. Median Citation Index vs Journal Impact Factor

    The Journal Impact Factor is an arithmetic mean: It is the average number of citations, in a year, to a journal's articles that were published the previous two years. But for the vast majority of scholarly journals, the distribution of these citations is skewed (non-symmetric). We argue that a more representative member of the skewed distribution of citations is its median, not the mean. We thus introduce the Median Citation Index (MCI) and compare it to the journal Impact Factor (JIF) as a potentially more suitable choice of the ``center'' of the distribution, or its typical value. Unlike the JIF, the MCI is far less sensitive to outlier (very highly cited) papers or to gaming, and does not lend itself to the hype of calculating it to three decimal digits.

    A large number of published studies have examined the properties of either networks of citation among scientific papers or networks of coauthorship among scientists. Here, using an extensive data set covering more than a century of physics papers published in the Physical Review, we study a hybrid coauthorship/citation network that combines the two, which we analyze to gain insight into the correlations and interactions between authorship and citation. Among other things, we investigate the extent to which individuals tend to cite themselves or their collaborators more than others, the extent to which they cite themselves or their collaborators more quickly after publication, and the extent to which they tend to return the favor of a citation from another scientist.

  7. Rescaling citations of publications in Physics

    We analyze the citation distributions of all papers published in Physical Review journals between 1985 and 2009. The average number of citations received by papers published in a given year and in a given field is computed. Large variations are found, showing that it is not fair to compare citation numbers across fields and years. However, when a rescaling procedure by the average is used, it is possible to compare impartially articles across years and fields. We make the rescaling factors available, for use by the readers. We also show that rescaling citation numbers by the number of publication authors has strong effects and should therefore be taken into account when assessing the bibliometric performance of researchers.

  9. What is the dimension of citation space?

    Citation networks represent the flow of information between agents. They are constrained in time and so form directed acyclic graphs which have a causal structure. Here we provide novel quantitative methods to characterise that structure by adapting methods used in the causal set approach to quantum gravity by considering the networks to be embedded in a Minkowski spacetime and measuring its dimension using Myrheim-Meyer and Midpoint-scaling estimates. We illustrate these methods on citation networks from the arXiv, supreme court judgements from the USA, and patents and find that otherwise similar citation networks have measurably different dimensions. We suggest that these differences can be interpreted in terms of the level of diversity or narrowness in citation behaviour.

    Colombian scientific journals are poorly represented in international digital libraries; however, through Google Scholar (GS) it is possible to determine their use by the community. Between the years of 2003 and 2007 a classification of 185 Colombian journals indexed in the Colombian National Bibliographical Index (IBNP) was performed using the information provided by GS, basing categorization on size indicators, indexation and citation. The indicators were analyzed by grouping the journals in two general areas: sciences and social sciences. In each area, the indicators provided by the digital libraries Scopus, Redalyc and Scielo were compared. Additionally, the indicators provided by IBNP journals categories (A1, A2, B and C) were also compared. The sciences and social sciences had a similar pattern in their indicators. The existence of positive correlations was established between some indicators and they predicted that the number of citations per journal in GS and the h index depends on its visibility in G...

    In scientific writing, positive credits and negative criticisms can often be seen in the text mentioning the cited papers, providing useful information about whether a study can be reproduced or not. In this study, we focus on citation sentiment analysis, which aims to determine the sentiment polarity that the citation context carries towards the cited paper. A citation sentiment corpus was annotated first on clinical trial papers. The effectiveness of n-gram and sentiment lexicon features, and problem-specified structure features for citation sentiment analysis were then examined using the annotated corpus. The combined features from the word n-grams, the sentiment lexicons and the structure information achieved the highest Micro F-score of 0.860 and Macro-F score of 0.719, indicating that it is feasible to use machine learning methods for citation sentiment analysis in biomedical publications. A comprehensive comparison between citation sentiment analysis of clinical trial papers and other general domains were conducted, which additionally highlights the unique challenges within this domain.

  16. The El Niño-Southern Oscillation cycle simulated by the climate system model of Chinese Academy of Sciences

    On the basis of more than 200-year control run, the performance of the climate system model of Chinese Academy of Sciences (CAS-ESM-C) in simulating the El Niño-Southern Oscillation (ENSO) cycle is evalu-ated, including the onset, development and decay of the ENSO. It is shown that, the model can reasonably simulate the annual cycle and interannual variability of sea surface temperature (SST) in the tropical Pacif-ic, as well as the seasonal phase-locking of the ENSO. The model also captures two prerequisites for the El Niño onset, i.e., a westerly anomaly and a warm SST anomaly in the equatorial western Pacific. Owing to too strong forcing from an extratropical meridional wind, however, the westerly anomaly in this region is largely overestimated. Moreover, the simulated thermocline is much shallower with a weaker slope. As a result, the warm SST anomaly from the western Pacific propagates eastward more quickly, leading to a faster develop-ment of an El Niño. During the decay stage, owing to a stronger El Niño in the model, the secondary Gill-type response of the tropical atmosphere to the eastern Pacific warming is much stronger, thereby resulting in a persistent easterly anomaly in the western Pacific. Meanwhile, a cold anomaly in the warm pool appears as a result of a lifted thermocline via Ekman pumping. Finally, an El Niño decays into a La Niña through their interactions. In addition, the shorter period and larger amplitude of the ENSO in the model can be attribut-ed to a shallower thermocline in the equatorial Pacific, which speeds up the zonal redistribution of a heat content in the upper ocean.

    Recent science of science research shows that scientific impact measures for journals and individual articles have quantifiable regularities across both time and discipline. However, little is known about the scientific impact distribution at the scale of an individual scientist. We analyze the aggregate production and impact using the rank-citation profile c(i)(r) of 200 distinguished professors and 100 assistant professors. For the entire range of paper rank r, we fit each c(i)(r) to a common distribution function. Since two scientists with equivalent Hirsch h-index can have significantly different c(i)(r) profiles, our results demonstrate the utility of the β(i) scaling parameter in conjunction with h(i) for quantifying individual publication impact. We show that the total number of citations C(i) tallied from a scientist's N(i) papers scales as [Formula: see text]. Such statistical regularities in the input-output patterns of scientists can be used as benchmarks for theoretical models of career progress.

    Recent "science of science" research shows common regularities in the publication patterns of scientific papers across time and discipline. Here we analyze the complete publication careers of 300 scientists and find remarkable regularity in the functional form of the rank-citation profile c_{i}(r) for each scientist i =1...300. We find that the rank-ordered citation distribution c_{i}(r) can be approximated by a discrete generalized beta distribution (DGBD) over the entire range of ranks r, which allows for the characterization and comparison of c_{i}(r) using a common framework. The functional form of the DGBD has two scaling exponents, beta_i and gamma_i, which determine the scaling behavior of c_{i}(r) for both small and large rank r. The crossover between two scaling regimes suggests a complex reinforcement or positive-feedback relation between the impact of a scientist's most famous papers and the impact of his/her other papers. Moreover, since two scientists with equivalent Hirsch h-index values may hav...

  19. Trends in citations to books on epidemiological and statistical methods in the biomedical literature.

    Full Text Available BACKGROUND: There are no analyses of citations to books on epidemiological and statistical methods in the biomedical literature. Such analyses may shed light on how concepts and methods changed while biomedical research evolved. Our aim was to analyze the number and time trends of citations received from biomedical articles by books on epidemiological and statistical methods, and related disciplines. METHODS AND FINDINGS: The data source was the Web of Science. The study books were published between 1957 and 2010. The first year of publication of the citing articles was 1945. We identified 125 books that received at least 25 citations. Books first published in 1980-1989 had the highest total and median number of citations per year. Nine of the 10 most cited texts focused on statistical methods. Hosmer & Lemeshow's Applied logistic regression received the highest number of citations and highest average annual rate. It was followed by books by Fleiss, Armitage, et al., Rothman, et al., and Kalbfleisch and Prentice. Fifth in citations per year was Sackett, et al., Evidence-based medicine. The rise of multivariate methods, clinical epidemiology, or nutritional epidemiology was reflected in the citation trends. Educational textbooks, practice-oriented books, books on epidemiological substantive knowledge, and on theory and health policies were much less cited. None of the 25 top-cited books had the theoretical or sociopolitical scope of works by Cochrane, McKeown, Rose, or Morris. CONCLUSIONS: Books were mainly cited to reference methods. Books first published in the 1980s continue to be most influential. Older books on theory and policies were rooted in societal and general medical concerns, while the most modern books are almost purely on methods.
