    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.

  4. A Comparison between the China Scientific and Technical Papers and Citations Database and the Science Citation Index in terms of journal hierarchies and inter-journal citation relations

    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.

  5. The Citation Impacts and Citation Environments of Chinese Journals in Mathematics

    2009-01-01

    Based on the citation data of journals covered by the China Scientific and Technical Papers and Citations Database (CSTPCD), we obtained aggregated journal-journal citation environments by applying routines developed specifically for this purpose. Local citation impact of journals is defined as the share of the total citations in a local citation environment, which is expressed as a ratio and can be visualized by the size of the nodes. The vertical size of the nodes varies proportionally to a journal's total citation share, while the horizontal size of the nodes is used to provide citation information after correction for the within-journal (self-) citations. In this study, we analyze citation impacts of three Chinese journals in mathematics and compare local citation impacts with impact factors. Local citation impacts reflect a journal's status and function better than (global) impact factors. We also found that authors in Chinese journals prefer international instead of domestic ones as sources for their ci...

    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.

  10. Data Identifiers and Citations Enable Reproducible Science

    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.

    2010-01-01

    The online information resources available to the CERN Community have recently increased by an additional database: Web of Science. WoS is a collection of several databases, among them the Science Citation Index, the Conference Proceedings Index and the Journal Citation Reports. The first two products allow you to perform subject, author and title searches, and most importantly you can obtain a list of papers citing a specific article, or navigate to the articles cited by the same article. Besides the retrieval and navigation features, analytical tools allow you to produce statistics and graphs describing the impact of a publication. Finally, the Journal Citation Reports database provides you with the well known – and often disputed – Impact Factor.

    By the empirical analysis of web citation of Chinese library and information science journals, this paper finds out that the citation of. html format papers is decreasing year by year, while the. pdf format and dynamic web one are gradually rising; academic information on wikis, blogs, forums and other new web are accepted by Chinese library and information science scholars; the accessibility of dynamic web citation is slightly higher than that of static web citation, and cites of them are between 50% and 51% ; web citations distributed in the . edu domain has the worst accessibility. And the related reasons are analyzed.%通过对我国图书情报学期刊网络引文的实证分析,得出如下结论:HTML格式网络引文的比例在逐年下降,PDF格式和动态类网络引文的比例在逐渐上升,维基、博客、论坛等新型网络学术信息正日益得到我国图书情报学者的认可和接受;动态类网络引文的可追溯性略高于静态类网络引文,但二者可追溯率都介于50%-51%之间;分布在.edu域名的网络引文的可追溯性相对较差。

  14. 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...

    2006-01-01

    INTRODUCTION: Citation indexes are produced by counting de-contextualised citations, which result from the transformation of references into citations, generating two different objects -two different signs-. This causes an ambiguity of both signs which is relevant for citation indexes and for science evaluation. METHODOLOGY: Two methods were used: 1) Qualitatively: It is performed a semiotic analysis in order to distinguish between bibliographic references and citations in terms of electronic...

  1. 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...

    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

    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.

    Mu-Hsuan Huang

    2008-12-01

    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

    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.

  11. World citation and collaboration networks: uncovering the role of geography in science

    CERN Document Server

    Pan, Raj Kumar; Fortunato, Santo

    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...

  12. Capturing citation activity in three health sciences departments: a comparison study of Scopus and Web of Science.

    Sarkozy, Alexandra; Slyman, Alison; Wu, Wendy

    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...

    From its very beginnings, regional science has been open to intellectual exchange with many other scientific disciplines. This has led to cross-fertilization, but also to problems concerning the intellectual identity of regional science. After half a century of history of the field, it is time to ask the question, whether or not regional science has developed into a scientific discipline in these decades. In this paper we use cross-citation data between 464 journals in different disciplines t...

    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.

  1. Indicators of Structural Change in the Dynamics of Science: Entropy Statistics of the SCI Journal Citation Reports

    2009-01-01

    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.

  3. 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.

    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.

    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.

  9. 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.

  14. Measuring science–technology interactions using patent citations and author-inventor links: an exploration analysis from Chinese nanotechnology

    International Nuclear Information System (INIS)

    This article contributes to the growing study on the interactions between science and technology with China’s evidence in the field of nanotechnology, based on the database of United States Patent and Trademark Office. The analysis is focused during the period of 1991–2008, a rapid increasing period for the development of nanotechnology. Using the non-patent references cited by patents, we first investigate the science–technology connections in the context of Chinese nanotechnology, especially in institutional sectors and its application fields. Those patents, produced by academic researchers and directed towards basic scientific knowledge, generally cite more scientific references with a higher proportion of self-citations. It is interesting to find that patents contributed by collaborations between public organizations and corporations seldom contain scientific references. Following an interesting path on matching the data of publications and patents, we establish the author-inventor links in this emerging field. Author-inventors, who are co-active in publishing and patenting, are at the very top of the most prolific and highly cited researchers. Finally, we employ social network analysis to explore the characteristics of scientific and technological networks generated by co-authorship and co-invention data, to investigate the position and the role of patenting–publishing scientists in these research networks.

    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....

    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

Defined and tested were three types of self-citations that differ in the set of authors when comparing the article and its citation: total self-citations, author’s self-citations and COBISS self-citations according to ARRS methodology. The cumulative values for the entire publication period and individual years of citation were analyzed in more detail.Results: The study showed that there are no significant differences between the selfcitation patterns of Slovenian researchers in WoS and Scopus, and that the comparability according to ARRS methodology with self-citation when taking into account the only first author is significantly larger than with self-citation when taking into account all of the articles’ co-authors.Research limitation: The study was limited to analyses and comparisons of self-citations according to the selected types of self-citation calculation on the national macro level. For a more detailed analysis of self-citation for Slovenian authors the study would have to be extended to the lower levels (e.g. by scientific disciplines and additional indicators (e.g. self-citation according to the number of authors.Originality/Practical implications: A special feature of this study is the selection and comparison of three different algorithms for self-citation calculation for almost the entire Slovenian

    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

    CERN Document Server

    Leydesdorff, Loet

    2012-01-01

    In 2011, Thomson-Reuters introduced the Book Citation Index (BCI) as part of the Science Citation Index (SCI). The interface of the Web of Science version 5 enables users to search for both "Books" and "Book Chapters" as new categories. Books and book chapters, however, were always among the cited references, and book chapters have been included in the database since 2005. We explore the two categories with both BCI and SCI, and in the sister databases for the social sciences (SoSCI) and the arts and humanities (A&HCI). Book chapters in edited volumes can be highly cited. Books contain many citing references, but are relatively less cited. We suggest that this may find its origin in the slower circulation of books then of journal articles. It is possible to distinguish scientometrically between monographs and edited volumes among the "Books". Monographs may be underrated in terms of citation impact or overrated using publication performance indicators because individual chapters are counted separately as ...

    This descriptive study evaluated behavioral and social science research on sport for 1993 through 2008, examined the characteristics of sport research, and identified mainstream issues appearing during these 16 years. Based on the Social Science Citation Index (SSCI) database from 1993 to 2008, 7,655 articles referring to sport or sports were available. The publication analyses showed that 13 core journals published the most articles in the behavioral sciences of sport. By analyzing all titles, author keywords, and KeyWords Plus, the results showed that physical education, athlete performance, and sports participation were the mainstream issues of sport research in the 16-year study period. The words adolescent, youth, and children frequently appeared, indicating that the emphasis of sport research focused on these participant groups. This bibliometric study reviewed global sports research in SSCI, and described certain patterns or trends in prior research on sport.

    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...

    Full Text Available 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.

  13. Tenure-Track Science Faculty and the 'Open Access Citation Effect'

    Directory of Open Access Journals (Sweden)

    R. Christopher Doty

    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.

    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.

    Leydesdorff, Loet; Wagner, Caroline

    2013-01-01

    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 ...

    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.

    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 main purpose of this paper is to investigate the intellectual structure of the research on educational technology in science education (ETiSE) within the most recent years (2008-2013). Based on the criteria for educational technology research and the citation threshold for educational co-citation analysis, a total of 137 relevant ETiSE papers were identified from the International Journal of Science Education, the Journal of Research in Science Teaching, Science Education, and the Journal of Science Education and Technology. Then, a series of methodologies were performed to analyze all 137 source documents, including document co-citation analysis, social network analysis, and exploratory factor analysis. As a result, 454 co-citation ties were obtained and then graphically visualized with an undirected network, presenting a global structure of the current ETiSE research network. In addition, four major underlying intellectual subfields within the main component of the ETiSE network were extracted and named as: (1) technology-enhanced science inquiry, (2) simulation and visualization for understanding, (3) technology-enhanced chemistry learning, and (4) game-based science learning. The most influential co-citation pairs and cross-boundary phenomena were then analyzed and visualized in a co-citation network. This is the very first attempt to illuminate the core ideas underlying ETiSE research by integrating the co-citation method, factor analysis, and the networking visualization technique. The findings of this study provide a platform for scholarly discussion of the dissemination and research trends within the current ETiSE literature.

    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.

    2008-10-01

    Full Text Available The Chinese Academy of Sciences (CAS produces the scientific and technological breakthroughs that place China among the major players in scientific innovation. However, the control that the Chinese government exerts over the Academy and the tradition of guanxi among its members prevent the CAS from take-off and securing a free environment to conduct original research. The article assesses the economic logic of scientific control and its effects within the Chinese Academy of Sciences. The paper’s aim is to derive to what extent the CAS will remain as China’s main provider of scientific innovation. The “national innovation systems” approach and the cultural traditions rooted in Confucianism are revised in detail to provide an accurate perspective. The paper concludes that the CAS’ international reputation as a center of scientific and technological innovation might be at stake unless the Chinese government makes some critical reforms.

    This study examines the determinants of citation success among authors who have recently published their work in economic history journals. 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....

  11. The Cosmopolitanization of Science: Experience from Chinese Stem Cell Scientists.

    Science.gov (United States)

    Zhang, Joy Yueyue

    2010-09-01

    It is commonly perceived that the 'globalization of science' may result in a 'Westernization of science'. In this paper, however, I use the case of stem cell science in China to demonstrate that developing countries are sometimes able to effectively shape the norms of global/local scientific exchange. Based on interviews with 38 stem cell scientists in six Chinese cities in early 2008, this paper elucidates Chinese scientists' outlook towards cross-border collaborations and the effects that the internationalization of science has had on everyday laboratory operations. Findings suggest that although there still exists an asymmetry of scientific influence, and in many aspects China is still 'catching-up' to the West, there is also a changing nature of communication beyond borders. One key aspect of recent international scientific development is the growing necessity for local stakeholders to acquire a global mindset and to compare, reflect and accommodate diverse interests. This is what I define as the 'cosmopolitanization of science'. The study empirically examines the sociological and methodological implications of the cosmopolitanization process and further develops Ulrich Beck's cosmopolitan theory by delineating four main features of the 'cosmopolitanization of science': shared future benefits, passive ethicization, reflexive negotiation, and continuous performance.

Remarkably, publishing in top-ranked journals hardly...... affects citations. In regard to author-specific characteristics, male authors, full professors and authors working economics or history departments, and authors employed in Anglo-Saxon countries, are more likely to get cited than others.

    This study aimed to identify and to analyze characteristics of top-cited articles published in the Web of Science chemical engineering subject category from 1899 to 2011. Articles that have been cited more than 100 times were assessed regarding publication outputs, and distribution of outputs in journals. Five bibliometric indica- tors were used to evaluate source countries, institution and authors. A new indicator, Y-index, was created to assess quantity and quality of contribution to articles. Results showed that 3828 articles, published between 1931 and 2010, had been cited at least 100 times. Among them 54% published before 1991, and 49% top-cited articles originated from US. The top eight productive institutions were all located in US. The top journals were Journal of Catalysis, AIChE Journal, Chemical Engineering Science and Journal of Membrane Science. Y-index was successfully ap- plied to evaluate publication character of authors, institutions, and countries/regions.

    Stephen Hall, a freelance science writer and science-communication teacher, received the Walter Sullivan Award for Excellence in Science Journalism-Features at the AGU Fall Meeting Honors Ceremony, held on 5 December 2012 in San Francisco, Calif. Hall was honored for the article "At Fault?" published 15 September 2011 in Nature. The article examines the legal, personal, and political repercussions from a 2009 earthquake in L'Aquila, Italy for seismologists who had attempted to convey seismic risk assessments to the public. The 6.3 magnitude quake devastated the medieval town and caused more than 300 deaths. Six scientists and one government official were subsequently convicted of manslaughter and sentenced to prison for inadequately assessing and mischaracterizing the risks to city residents, despite the inexact nature of seismic risk assessment. The Sullivan award is for work published with a deadline pressure of more than 1 week.

  16. Scientific citations in Wikipedia

    CERN Document Server

    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

    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.

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.

    Nature of science (NOS) is beginning to find its place in the science education in China. In a study which investigated Chinese science teacher educators' conceptions of teaching NOS to prospective science teachers through semi-structured interviews, five key dimensions emerged from the data. This paper focuses on the dimension, NOS content to be taught to prospective science teachers. Among a total of twenty NOS elements considered by the Chinese science teacher educators to be important ideas to be taught, five were suggested by no less than a half of the educators. They are (1) empirical basis of scientific investigation, (2) logics in scientific investigation, (3) general process of scientific investigation, (4) progressive nature of scientific knowledge, and (5) realist views of mind and natural world. This paper discusses the influence of Marxism, a special socio-cultural factor in China, on Chinese science teacher educators' conceptions of NOS content to be taught to prospective science teachers. We argue the importance of considering ideological traditions (mainly those in general philosophy and religion) when interpreting views of NOS or its content to be taught in different countries and regions and understanding students' conceptual ecology of learning NOS.

    Looking at the development of subject librarians and subject services in Chinese libraries during the past decade,this paper highlights the innovative concepts and practices of subject librarians in National Science Library(NSL),Chinese Academy of Sciences(CAS).After a two-year trial period,NSL,CAS,with 39 full-time subject librarians,has begun to provide personalized,subject-specific,and knowledge-based services to the end-users since 2006.Such a practice manifests that subject librarians and subject services should be embedded into the research process and working environment.And,the subject service should be made available to the users beyond the space restriction and time limit,and finally create a congenial environment for users.Librarians should develop new expertise to offer the user-oriented service,changing the role from book keepers to research instructors,advisors,even chief information officer(CIO)or chief knowledge officer(CKO).

  4. Careers of an elite cohort of U.S. basic life science postdoctoral fellows and the influence of their mentor's citation record

    2010-11-01

    Full Text Available Abstract Background There is general agreement that the number of U.S. science PhDs being trained far exceeds the number of future academic positions. One suggested approach to this problem is to significantly reduce the number of PhD positions. A counter argument is that students are aware of the limited academic positions but have chosen a PhD track because it opens other, non-academic, opportunities. The latter view requires that students have objective information about what careers options will be available for them. Methods The scientific careers of the 1992-94 cohort of NIH National Institute of General Medical Sciences (NIGMS Kirchstein-NRSA F32 postdoctoral fellows (PD was determined by following their publications (PubMed, grants (NIH and NSF, and faculty and industry positions through 2009. These basic life science PDs receive support through individual grant applications and represent the most successful class of NIH PDs as judged by academic careers and grants. The sex dependence of the career and grant success and the influence of the PD mentor's citation record were also determined Results Of the 439 1992-94 NIGMS F32 fellows, the careers of 417 could be determined. Although females had significantly higher rates of dropping out of science (22% females, 9% males there was no significant difference in the fraction of females that ended up as associate or full professors at research universities (22.8% females, 29.1% for males. More males then females ended up in industry (34% males, 22% females. Although there was no significant correlation between male grant success and their mentor's publication record (h index, citations, publications, there was a significant correlation for females. Females whose mentor's h index was in the top quartile were nearly 3 times as likely to receive a major grant as those whose mentors were in the bottom quartile (38.7% versus 13.3%. Conclusions Sixteen years after starting their PD, only 9% of males

  5. Central-European Jesuit Scientists in China, and Their Impact on Chinese Science

    Directory of Open Access Journals (Sweden)

    Stanislav Jože JUŽNIČ

    2015-12-01

    The Jesuits acted as intermediate in the exchange of know-how between Europe and China. In modern Chinese eyes they were also somewhat viewed as spies, who helped European military and economic victories in the mid-19th century. Modern China is now as strong as it was in the times of Old Jesuit Society, therefore the Europocentric history of science must be rewritten from the standpoint of today’s winning Chinese economy. What kind of science will Western Civilization import from the future Chinese literati? The Jesuits’ transfer of European Sciences to the Far-Easterners caused the reverse impact from seemingly less developed centers of Far East that was felt in Jesuits’ times, but much more is to follow in the near future. We could expect the fundamental future Chinese achievements in cosmology, especially in Einstein’s general theory of relativity.

  6. Do citation systems represent theories of truth?

    2001-01-01

    Full Text Available This article suggests that the citation can be viewed not only as a "concept symbol" but also as a "boundary object". The scientific, legal, and patent citation systems in America are examined at the micro, meso, and macro levels in order to understand how they function as commodified theories of truth in contemporary knowledge representation. This approach also offers a meta-theoretical overview of existing citation research efforts in science, law, and technology that may be of interdisciplinary interest.

  7. Aberration of the Citation.

    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. PMID:26636372

    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.

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. Of all fields in NSE and SSH, only engineering has increased the proportion of proceedings citations, rising from 7% to 10% in the period studied. In 2005, the share of proceedings

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

    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.

    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.

However, the distinction of citedness score exists in heterogeneous information systems resulted from considerations for system construction and development, such as purpose, procedure and policy of data processing, and that would bring various meanings and impacts for citedness score. This paper aims to examine the distinctive factors and results on calculation of citedness score of scholarly literatures between Science Citation Index Expanded and Scopus by adoption of

    2011-01-01

    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. The I3 indicator was introduced by Leydesdorff and Bornmann (in press).

    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

    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.

    Full Text Available The aim of this research was to investigate the effect of co-authorship and self-citation on the citation rates of Iranian indexed articles in Web of Science (WoS. Research population included Iranian indexed articles in WoS in 2007 which had been received at least one citation. Numbers of articles in the time of research (October & November 2010 was 7355, which 390 of them, using stratified random sampling, was selected as sample. Research results showed that co-authored articles have received more citations than single-authored ones and this difference was statistically significant. On the other hand, self-citation exclusion has significantly reduced the citation rates of both co-authored and single-authored articles. After self-citation exclusion, existing difference between citation rates of co-authored and single-authored articles lost its significance. So, it can be concluded that self-citation exclusion led to reduction of citation rates of Iranian indexed articles in WoS, but this exclusion affected co-authored articles citation rates more than single-authored ones. In other words, high citation of Iranian co-authored articles in comparison with single-authored articles has been affected mainly by self-citation, not by foreign citation. This finding, which was our contribution, contradicted with results of previous researches.

    Drawing from the phenomenographic perspective, an exploratory study investigated Chinese teacher educators' conceptions of teaching Nature of Science (NOS) to pre-service science teachers through semi-structured interviews. Five key dimensions emerged from the data. This paper focuses on the dimension, NOS content to be taught to pre-service science teachers. A total of 20 NOS elements were considered by the Chinese science teacher educators to be important ideas to be taught. It was also found that among these educators, whether focusing on the classical or contemporary NOS elements in NOS instruction was a prominent controversy. After explaining the criteria for differentiating between classical and contemporary NOS elements, this paper reports the specific NOS elements suggested by Chinese science teacher educators in this study. Afterward, it describes how all educators in this study were categorized in term of NOS content taught by them to pre-service science teachers. In the end, it discusses three factors influencing the decision on NOS content to be taught, i.e., view of the concept of NOS itself, vision of teaching NOS, and belief in general philosophy.

    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. . .

    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.

    Dongeuibogam is the most prestigious traditional medical book in Korea, written by Heo Joon, who codified it by picking the essence of Chinese traditional medical books before the Ming Dynasty and some other ancient Chinese books and sorted them out. Among the citations of this book, those marked as"Herbal" is more complicated. We made a preliminary research on the citations of such Herbal, from their distribution, sources, citation manners, pharmacological features, to find that 23 rolls of main text to include citations of Herbal in each roll. We also found that most Herbal referred by Heo Joon come from Zheng lei ben cao (Classified Materia Medica), and a few of the contents are mixed with the contents of other medical books. Heo Joon abstracted and modified the citations from the source literature, embodying his ideas of pursuing conciseness and practicability. PMID:25429883

    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.

  15. 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...

    Children have formal science instruction from kindergarten in Australia and from Year 3 in China. The purpose of this research was to explore the impact that different approaches to primary science curricula in China and Australia have on children's conceptual understanding of science. Participants were Year 3 children from three schools of high, medium and low socio-economic status in Hunan Province, central south China (n = 135) and three schools of similar socio-economic status in Western Australia (n = 120). The students' understanding was assessed by a science quiz, developed from past Trends in Mathematics and Science Study science released items for primary children. In-depth interviews were carried out to further explore children's conceptual understanding of living things, the Earth and floating and sinking. The results revealed that Year 3 children from schools of similar socio-economic status in the two countries had similar conceptual understandings of life science, earth science and physical science. Further, in both countries, the higher the socio-economic status of the school, the better the students performed on the science quiz and in interviews. Some idiosyncratic strengths and weaknesses were observed, for example, Chinese Year 3 children showed relative strength in classification of living things, and Australian Year 3 children demonstrated better understanding of floating and sinking, but children in both countries were weak in applying and reasoning with complex concepts in the domain of earth science. The results raise questions about the value of providing a science curriculum in early childhood if it does not make any difference to students' conceptual understanding of science.

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

    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.

    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...

    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...

    2012-01-01

    This paper proposes a new framework for Citation Content Analysis (CCA), for syntactic and semantic analysis of citation content that can be used to better analyze the rich sociocultural context of research behavior. The framework could be considered the next generation of citation analysis. This paper briefly reviews the history and features of content analysis in traditional social sciences, and its previous application in Library and Information Science. Based on critical discussion of the theoretical necessity of a new method as well as the limits of citation analysis, the nature and purposes of CCA are discussed, and potential procedures to conduct CCA, including principles to identify the reference scope, a two-dimensional (citing and cited) and two-modular (syntactic and semantic modules) codebook, are provided and described. Future works and implications are also suggested.

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.

  1. Citation pattern of newsworthy research articles

    Directory of Open Access Journals (Sweden)

    Manjari Manisha

    2015-01-01

    Full Text Available Popular science magazines cover research articles published in scholarly journals that the magazines perceive as having news value. Despite thousands of research articles being published in research journals, a very few get identified for coverage in popular science magazines, general magazines, and newspapers. Do research articles published in journals that are covered in popular science magazines receive higher citations? We hypothesize that newsworthy articles should receive higher citations as the newsworthiness can be a reflection of higher research value of the articles and also because of the visibility received by the articles owing to its coverage in popular science magazine. To empirically study the citedness, we identified 193 research articles and that were reported in New Scientist magazine in 2001. The characteristics of these articles including the citations received following coverage in New Scientist in 2001 were looked at. It was found that average citations per paper of articles covered in New Scientist was higher than the journal average for the year 2001 for 19 out of the 24 journals identified here.

    Full Text Available Aim: Informal citations is bibliographic information (title or Internet address, citing sources of information resources for informal scholarly communication and always neglected in traditional citation databases. This study is done, in order to answer the question of whether informal citations in the web environment are traceable. 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

    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.

    We study the statistics of citations made to the indexed Science journals in the Journal Citation Reports during the period 2004-2013 using different measures. We consider different measures which quantify the impact of the journals. 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.

    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...

  9. The correlation between pertinence and rate of citation duplication in multidatabase searches.

    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.

    2015-05-01

    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

    Goldberg, S R; Evans, T S

    2014-01-01

    The distribution of the number of academic publications as a function of citation count for a given year is remarkably similar from year to year. We measure this similarity as a width of the distribution and find it to be approximately constant from year to year. We show that simple citation models fail to capture this behaviour. We then provide a simple three parameter citation network model using a mixture of local and global search processes which can reproduce the correct distribution over time. We use the citation network of papers from the hep-th section of arXiv to test our model. For this data, around 20% of citations use global information to reference recently published papers, while the remaining 80% are found using local searches. We note that this is consistent with other studies though our motivation is very different from previous work. Finally, we also find that the fluctuations in the size of an academic publication's bibliography is important for the model. This is not addressed in most mode...

    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.

  15. Patent citation network in nanotechnology (1976-2004)

    International Nuclear Information System (INIS)

    The patent citation networks are described using critical node, core network, and network topological analysis. The main objective is understanding of the knowledge transfer processes between technical fields, institutions and countries. This includes identifying key influential players and subfields, the knowledge transfer patterns among them, and the overall knowledge transfer efficiency. The proposed framework is applied to the field of nanoscale science and engineering (NSE), including the citation networks of patent documents, submitting institutions, technology fields, and countries. The NSE patents were identified by keywords 'full-text' searching of patents at the United States Patent and Trademark Office (USPTO). The analysis shows that the United States is the most important citation center in NSE research. The institution citation network illustrates a more efficient knowledge transfer between institutions than a random network. The country citation network displays a knowledge transfer capability as efficient as a random network. The technology field citation network and the patent document citation network exhibit a less efficient knowledge diffusion capability than a random network. All four citation networks show a tendency to form local citation clusters

  1. A small world of citations? The influence of collaboration networks on citation practices

    CERN Document Server

    Wallace, Matthew L; Gingras, Yves

    2011-01-01

    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...

    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.

  6. Indicators of the Interdisciplinarity of Journals: Diversity, Centrality, and Citations

    CERN Document Server

    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 ...

    Morrison' at CERN notes regional variation in fusion cell results and various workers have ascribed this to possible sociological factors. 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.

    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.

    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...

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.

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.

    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.

    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.

    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.

    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.

    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. Self-promoting journal self-citations of top-tier journals have rather indirect but negligible direct effects on bibliometric indicators, affecting just the immediacy index and marginally increasing the impact factor itself as long as the affected journals are well established in their fields. In contrast, other forms of journal self-citations and citation stacking may severely affect the impact factor, or other citation-based indices. We identified here a network consisting of three Romanian physics journals Proceedings of the Romanian Academy, Series A, Romanian Journal of Physics, and Romanian Reports in Physics, which displayed low to moderate ratio of journal self-citations, but which multiplied recently their impact factors, and were mutually responsible for 55.9%, 64.7% and 63.3% of citations within the impact factor calculation window to the three journals

  14. 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.

  15. Environment and Planning B as a Journal: The interdisciplinarity of its environment and the citation impact

    2009-01-01

    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.

  16. The Scientific Impact of Nations: Journal Placement and Citation Performance

    2014-01-01

    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. PMID:25296039

    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.

    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.

    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. PMID:27599104

    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.

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.

  9. Copied citations create renowned papers?

    OpenAIRE

    Simkin, M. V.; Roychowdhury, V. P.

    2003-01-01

    Recently we discovered (cond-mat/0212043) that the majority of scientific citations are copied from the lists of references used in other papers. Here we show that a model, in which a scientist picks three random papers, cites them,and also copies a quarter of their references accounts quantitatively for empirically observed citation distribution. Simple mathematical probability, not genius, can explain why some papers are cited a lot more than the other.

  10. Exploring the Composite Trace of Research Outputs of Humanities and Social Sciences Scholars: A Case Study of the Institute for Advanced Studies in Humanities and Social Sciences at National Taiwan University

    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

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

    Chorus, Caspar; Waltman, Ludo

    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.

    In this study, we aimed to compare the quantity and quality of publications in health care sciences and services journals from the Chinese mainland, Taiwan, Japan, and India. Journals in this category of the Science Citation Index Expanded were included in the study. Scientific papers were retrieved from the Web of Science online database. Quality was measured according to impact factor, citation of articles, number of articles published in top 10 journals, and the 10 most popular journals by country (area). In the field of health care sciences and services, the annual incremental rates of scientific articles published from 2007 to 2014 were higher than rates of published scientific articles in all fields. Researchers from the Chinese mainland published the most original articles and reviews and had the highest accumulated impact factors, highest total article citations, and highest average citation. Publications from India had the highest average impact factor. In the field of health care sciences and services, China has made remarkable progress during the past eight years in the annual number and percentage of scientific publications. Yet, there is room for improvement in the quantity and quality of such articles.

    2016-01-01

    We argue that citation is a composed indicator: short-term citations can be considered as currency at the research front, whereas long-term citations can contribute to the codification of knowledge claims into concept symbols. Knowledge claims at the research front are more likely to be transitory and are therefore problematic as indicators of quality. Citation impact studies focus on short-term citation, and therefore tend to measure not epistemic quality, but involvement in current discours...

    2012-05-15

    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. Based on the analysis, the paper suggests some ways to promoting the position of NET as a journal in the international nuclear sector

  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...

    2012-01-01

    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...

    Brzezinski, Michal

    2014-01-01

    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.

  5. Science Letters:Crossover randomized controlled trial of the electronic version of the Chinese SF-36

    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.

    Full Text Available Interrelation of models and theories of human information behaviour (HIB, their common roots, and the extent to which they are indebted to the fields other than library and information science (LIS were investigated. Fifty-one theories were selected and their bibliographic information was obtained from Web of Science and then citation analysis and bibliographic coupling analysis were performed. Pajek, HistCite, Sci2 Tool and VOSViewer software were used for analysis and visualization. The results showed that most of the theories were proposed by information scientists. A few of the theories were proposed by scientists from the fields of sociology, psychology, computer science and a few other disciplines. Citation analysis showed that LIS literature has been used extensively in HIB theories; however, there were also citations to the sources of 29 other fields especially to sociology, communication, psychology, management, educational science and computer science. This is an indication of the interdisciplinary nature of HIB domain. Bibliographic coupling map showed that about four fifths of the theories were linked to each other as a whole network. The development of a large number of theories within the field of LIS is an indication for the increasing maturity of the interdisciplinary research area of HIB as well as the maturity of LIS field.

    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.

    2015-12-01

    NASA's Earth Science Data and Information System (ESDIS) Project has been processing information for the registration of Digital Object Identifiers (DOI) for the last five years of which an automated system has been in operation for the last two years. The ESDIS DOI registration system has registered over 2000 DOIs with over 1000 DOIs held in reserve until all required information has been collected. By working towards the goal of assigning DOIs to the 8000+ data collections under its management, ESDIS has taken the first step towards facilitating the use of data citations with those products. When registering DOIs, ESDIS requires certain DOI elements be collected for the DOI landing page as recommended by NASA's Earth Science Data System Working Group (ESDSWG). The landing page provides sufficient information to 1) identify NASA data as referenced in a science publication, 2) credit data creators and distributors, and 3) access the data itself enabling the trace-ability and reproducibility of the data. However, the required elements for this DOI landing page are also the core required elements for forming an Earth science data citation. Data citations are getting significant attention from the scientific community and data centers alike. So to encourage the citing of Earth science data products, each product DOI landing page displays a sample data citation and makes the required citation elements available to DataCite for use in its Data Citation generation tool. This paper will describe that process. ESDIS data centers are constantly developing technologies to better serve the Earth science user community such as Geospatial Interactive Online Visualization ANd aNalysis Infrastructure (GIOVANNI), Land and Atmospheric Near Real-Time Capability for EOS (LANCE), and advanced tools that support virtual data collections, and virtual data products. These all provide easier access to data and make possible the creation of data products with user specified parameters

    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).

    2010-01-01

    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.

    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.

  2. Chinese medicine needs the baptism of science%中医需要接受科学洗礼

    古代东西方一切较为成熟的实用学术,诸如天文学、地理学、历法学、农学、建筑学以及医学等都有其一定的“科学内涵”,这些“科学内涵”都来自实践经验的逐渐积累和重复验证.古希腊医学具有容易接受“科学洗礼”的优势,其作为医学实践的认识和方法基础的哲学,包括“本体论”( ontology)和“逻辑学”(logics)能够有效地支持科学的发展.所以,随着西方文艺复兴时代以来自然科学的长足发展,希腊医学顺其自然地接受了“科学洗礼”,逐步发展为“现代医学”.近年来,西方学术界掀起了一股研究希腊医学的代表人物盖仑的著作的热潮,从而发掘和宣扬了希腊医学的重大的实用价值和历史价值.古代的中医学与希腊医学无论在理论上,还是在实践上都极其相似,各有千秋.然而,中医学缺乏自然哲学的有利支撑,几千年来“原汁原味”地传承,只有数量的丰富,而没有本质的蜕变.所以,中医学也应该像希腊医学一样接受“科学洗礼”,大浪淘沙,把其中的具有实用价值的真金淘洗出来,并且树立它的伟大的历史价值供后人凭吊.%All branches of mature practical technologies of both Eastern and Western ancient cultures, such as astronomy, geography, calendar, agriculture, architectonics, medicine, and so on, possess their own scientific connotation, which were derived from gradual accumulation and repeated validation of practical experiences. The ancient Greek medicine has the advantage of easily receiving scientific 'baptism' (reformation). The ontology and logics in ancient Greek philosophy, served as the epistemological and methodological bases, could effectively promote the development of science. Therefore, following the rapid progress of natural sciences since the Renaissance of the West world, the ancient Greek medicine rationally received the scientific " baptism" and gradually transformed into

  10. Epoch making NIRS studies seen through citation trends

    International Nuclear Information System (INIS)

    Near-infrared spectroscopy (NIRS) studies through citation trends are investigated of literature concerning only the brain function measurement and its methodology together with NIRS principle, technological development, present state and future view. Investigation is conducted firstly for the survey of important author name of those concerned papers in Web of Science and Google Scholar with search words of NIRS, brain and optical topography as an option. Second, >100 papers of those authors citing any of them are picked up and their papers are ranked in accordance with Web of Science citation number, of which top-nineteen are presented here. Impact and epoch making papers are reviewed with explanations of: the establishment of measuring technology of cerebral blood flow change and subsequent brain function by NIRS; development with multi-channel detection; simultaneous measurement with other imaging modalities; examination of NIRS validity; spatial analysis of NIRS; and measurement of brain function. The highest times of citation are 1,238 of the paper by F. F. Jobsis in 'Science' (1977). It should be noted that 10 of top 19 papers are those by Japanese authors. However, review articles omitted in the present literature survey are mostly described by foreign authors: an effort to systemize the concerned fields might be required in this country. (K.T.)

    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...

    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

    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....

    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. PMID:27499288

    Kuhn, Tobias; Perc, Matjaž; Helbing, Dirk

    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.

    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

    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...

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

    2015-01-01

    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.

  14. 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.

    Background:Neurosurgery in China has made great progress.The aim of this study was to analyze neurosurgical publications by Chinese authors using the Web of Science database as a way to illustrate the current state of neurosurgery in China.Methods:We searched the Web of Science core database for articles containing "neurosurg*" with or without an author address in "China" to obtain the set of neurosurgical publications in China and worldwide.We then extracted data from the search results to obtain information such as document type,countries/territories,organizations,publication year,title and research area.Then,we analyzed the search results of articles (document type) to generate a citation report.We identified publications by Chinese neurosurgeons that were cited more than 100 times.Results:A total of 165,365 neurosurgical publications were identified.Among them,10,770 were published by Chinese neurosurgeons.Chinese neurosurgical publications have increased year by year,accounting for 2 % of neurosurgical publications before 2010 and rising to 13 % from 2010 to the present.The most frequent journals for Chinese neurosurgeons differ from the most frequent journals worldwide.We identified 34 Chinese organizations that published more than 100 publications.We also identified 19 studies written by Chinese neurosurgeons that were cited more than 100 times.Basic research represents a large proportion of Chinese publications in this area,while clinical research remains a weak area.Cooperative studies were overrepresented among Chinese studies.Conclusion:While China's publication output in the area of neurosurgery has made great progress,significant room for improvement remains.The next step is to strengthen Chinese neurosurgical clinical studies and improve the publishing environment for Chinese neurosurgeons.

  19. An Evaluation of Impacts in "Nanoscience & nanotechnology:" Steps towards standards for citation analysis

    2011-01-01

    One is inclined to conceptualize impact in terms of citations per publication, and thus as an average. 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. The significance levels of results can thus be indicated. The results are first compared with the ISI-Impact Factors, but this Integrated Impact Indicator (I3) can be used with any set downloaded from the (Social) Science Citation Index. The software is made publicly available at the Internet. Visualization techniques are also specified for evaluation by positioning institut...

  6. 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...

    ; 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

  14. Linking to Data - Effect on Citation Rates in Astronomy

    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...

Furthermore that proved the trend of times that the development of sports depended on the science and technology. Throughout the development history of it, Chinese sports science and technology grew out of nothing, expanded from a small to a large, and improved from weak to strong. In the meanwhile, we should realized clearly there is still a gap between Chinese and world advanced level, that the external environment is not ideal, the quality of scientific personal is not high, the investment for developing the science and technology is not enough, the production of science and technology achievements is not too much and transfer of it is not very fast. In the 21st century, state government formulated the developing principle of improving the capability of independent innovation, establishing the innovative country. Taking it as a big opportunity, the Chinese science and technology should explore a way to independent

    This article attempts to discuss the ideology of indigenous orientation in recent Chinese social science. Many scholars think this orientation of thinking focusing on the indigenous Chinese culture context will lead to nationalism and imagined community. The misreading of this thinking way is that the Chinese culture is fixed, and the communication between cultures is neglected by these scholars. The author of this article argues that the cultural practice of indigenous movement is also another kind of westernized hegemony. All those cultural misreading has a common origin, that is the decline of cosmology of the Chinese empire and the expansive movement of indigenization for the purpose to defense mechanism in the ideology construction of modem Chinese state.

    In scientific circles, the reference is the information that is necessary to the reader in identifying and finding used sources. The basic rule when listing the sources used is that references must be accurate, complete and should be consistently applied. On the other hand, quoting implies verbatim written or verbal repetition of parts of the text or words written by others that can be checked in original. Authors of every new scientific article need to explain how their study or research fits with previous one in the same or similar fields. A typical article in the health sciences refers to approximately 20-30 other articles published in peer reviewed journals, cite once or hundreds times. Citations typically appear in two formats: a) as in-text citations where the sources of information are briefly identified in the text; or b) in the reference list at the end of the publication (book chapter, manuscript, article, etc.) that provides full bibliographic information for each source.

    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.

    2013-01-01

    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. What is the dimension of citation space?

    Clough, James R.; Evans, Tim S.

    2016-04-01

    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.

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

    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) sugges...

  9. 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...

    Full Text Available Open access (OA to the research literature has the potential to accelerate recognition and dissemination of research findings, but its actual effects are controversial. This was a longitudinal bibliometric analysis of a cohort of OA and non-OA articles published between June 8, 2004, and December 20, 2004, in the same journal (PNAS: Proceedings of the National Academy of Sciences. Article characteristics were extracted, and citation data were compared between the two groups at three different points in time: at "quasi-baseline" (December 2004, 0-6 mo after publication, in April 2005 (4-10 mo after publication, and in October 2005 (10-16 mo after publication. Potentially confounding variables, including number of authors, authors' lifetime publication count and impact, submission track, country of corresponding author, funding organization, and discipline, were adjusted for in logistic and linear multiple regression models. A total of 1,492 original research articles were analyzed: 212 (14.2% of all articles were OA articles paid by the author, and 1,280 (85.8% were non-OA articles. In April 2005 (mean 206 d after publication, 627 (49.0% of the non-OA articles versus 78 (36.8% of the OA articles were not cited (relative risk = 1.3 [95% Confidence Interval: 1.1-1.6]; p = 0.001. 6 mo later (mean 288 d after publication, non-OA articles were still more likely to be uncited (non-OA: 172 [13.6%], OA: 11 [5.2%]; relative risk = 2.6 [1.4-4.7]; p < 0.001.

    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.

  5. Statistical regularities in the rank-citation profile of scientists

    Petersen, Alexander M; Succi, Sauro

    2011-01-01

    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...

    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...

    Traditional Chinese medicine (TCM) rehabilitation science has features of both TCM and modern rehabilitation science, which contain and depend on each other. It not only has the unique feature of rehabilitation science based on biological-psychological-social medical model, but also has the core ideology of holism concept and syndrome differentiation and treatment. The concept connotation of TCM rehabilitation science mainly includes two aspects: rehabilitation science in TCM and TCM in rehabilitation science. The extension of the concept of TCM rehabilitation is mainly embodied in aspect of combination and development of TCM and rehabilitation. The deep layer in extension is the results of integration of TCM theories and modern medical theories. Understanding the concept connotation and extension of TCM rehabilitation science would have advantage in exploring and sorting out the TCM rehabilitation theory and rehabilitation therapy. The application of modern science and technology in clinical and experimental research can greatly promote TCM rehabilitation therapy, enrich medical contents, and form a theoretical system of TCM rehabilitation science with unique style.%中医康复学同时具备中医学和现代康复学 2 个特征,两者之间相互包容,相互依托,不仅具备建立在生物-心理-社会医学模式之上康复医学的独有特征,而且具备整体观念和辨证论治两大中医学理论体系的核心理念.中医康复学的概念内涵主要包括中医的康复学和康复的中医学 2 个层面.中医康复学概念外延主要体现在中医和康复互相结合发展层面,更深层外延则是传统中医理念与现代医学理念融会贯通的结果.理解中医康复学概念内涵和外延,对于发掘和整理中医康复理论和康复疗法有积极作用.应用现代科学技术深入进行临床及实验研究,把中医康复疗法推进到更高水平,必将极大地丰富康复医学内容,从而形成独具风格的中医康复学理论体系.

    Full Text Available Abstract CiTO, the Citation Typing Ontology, is an ontology for describing the nature of reference citations in scientific research articles and other scholarly works, both to other such publications and also to Web information resources, and for publishing these descriptions on the Semantic Web. Citation are described in terms of the factual and rhetorical relationships between citing publication and cited publication, the in-text and global citation frequencies of each cited work, and the nature of the cited work itself, including its publication and peer review status. This paper describes CiTO and illustrates its usefulness both for the annotation of bibliographic reference lists and for the visualization of citation networks. The latest version of CiTO, which this paper describes, is CiTO Version 1.6, published on 19 March 2010. CiTO is written in the Web Ontology Language OWL, uses the namespace http://purl.org/net/cito/, and is available from http://purl.org/net/cito/. This site uses content negotiation to deliver to the user an OWLDoc Web version of the ontology if accessed via a Web browser, or the OWL ontology itself if accessed from an ontology management tool such as Protégé 4 (http://protege.stanford.edu/. Collaborative work is currently under way to harmonize CiTO with other ontologies describing bibliographies and the rhetorical structure of scientific discourse.

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

    Directory of Open Access Journals (Sweden)

    Miquel Porta

    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.

  16. Citation Semantic Based Approaches to Identify Article Quality

    2013-05-01

    Full Text Available Analyzing the structure of research articles and th e relationship between the articles has always been important in bibliometrics research area. One of the methods for analyzing articles is by its citation. Normally researchers rank the article based on the citation count. But this quantity based evaluation is not sufficient due to various c itation types like Random citation, Guest citation. Our paper aims in providing a new method to rate a research paper based on its citation quality. In order to find the citation qua lity, three different semantic related processes are used: Citation classification, Citation Sentime nt Analysis, Content Relevancy. This work analyzes some challenges found in citing a research paper. We have proposed methods to figure out the valid citations for research paper and ther eby found quality of the research paper.

  17. Clustering scientific publications based on citation relations: A systematic comparison of different methods

    Šubelj, Lovro; Waltman, Ludo

    2015-01-01

    Clustering methods are applied regularly in the bibliometric literature to identify research areas or scientific fields. These methods are for instance used to group publications into clusters based on their relations in a citation network. In the network science literature, many clustering methods, often referred to as graph partitioning or community detection techniques, have been developed. Focusing on the problem of clustering the publications in a citation network, we present a systematic comparison of the performance of a large number of these clustering methods. Using a number of different citation networks, some of them relatively small and others very large, we extensively study the statistical properties of the results provided by different methods. In addition, we also carry out an expert-based assessment of the results produced by different methods. The expert-based assessment focuses on publications in the field of scientometrics. Our findings seem to indicate that there is a trade-off between di...

    In this work, we study the correlation between interdisciplinarity of papers within physical sciences and their citations by using meta data of articles published in American Physical Society's Physical Review journals between 1985 to 2012. We use the Weitzman diversity index to measure the diversity of papers and authors, exploiting the hierarchical structure of PACS (Physics and Astronomy Classification Scheme) codes. We find that the fraction of authors with high diversity is increasing with time, where as the fraction of least diversity are decreasing, and moderate diversity authors have higher tendency to switch over to other diversity groups. The diversity index of papers is correlated with the citations they received in a given time period from their publication year. Papers with lower and higher end of diversity index receive lesser citations than the moderate diversity papers.

  19. Do PageRank-based author rankings outperform simple citation counts?

    CERN Document Server

    Fiala, Dalibor; Žitnik, Slavko; Bajec, Marko

    2015-01-01

    The basic indicators of a researcher's productivity and impact are still the number of publications and their citation counts. These metrics are clear, straightforward, and easy to obtain. When a ranking of scholars is needed, for instance in grant, award, or promotion procedures, their use is the fastest and cheapest way of prioritizing some scientists over others. However, due to their nature, there is a danger of oversimplifying scientific achievements. Therefore, many other indicators have been proposed including the usage of the PageRank algorithm known for the ranking of webpages and its modifications suited to citation networks. Nevertheless, this recursive method is computationally expensive and even if it has the advantage of favouring prestige over popularity, its application should be well justified, particularly when compared to the standard citation counts. In this study, we analyze three large datasets of computer science papers in the categories of artificial intelligence, software engineering,...

  20. Coauthorship and Citation Networks for Statisticians

    CERN Document Server

    Ji, Pengsheng

    2014-01-01

    We have collected and cleaned two network data sets: Coauthorship and Citation networks for statisticians. The data sets are based on all research papers published in four of the top journals in statistics from 2003 to the first half of 2012. We analyze the data sets from many different perspectives, focusing on (a) productivity, patterns and trends, (b) centrality, and (c) community structures, and present an array of interesting findings. For (a), we find that over the 10-year period, both the average number of papers per author and the fraction of self citations have been decreasing, but the proportion of distant citations has been increasing. These suggest that the statistics community has become increasingly more collaborative, competitive, and globalized, driven by the boom of online resources and Search Engines. For (b), we identify the most prolific, the most collaborative, and the most highly cited authors. We also identify a handful of "hot" papers and suggest "Variable Selection" and several other ...

  1. Impact maturity times and citation time windows: The 2-year maximum journal impact factor

    CERN Document Server

    Dorta-Gonzalez, Pablo

    2013-01-01

    Journal metrics are employed for the assessment of scientific scholar journals from a general bibliometric perspective. In this context, the Thomson Reuters journal impact factors (JIF) are the citation-based indicators most used. The 2-year journal impact factor (2-JIF) counts citations to one and two year old articles, while the 5-year journal impact factor (5-JIF) counts citations from one to five year old articles. Nevertheless, these indicators are not comparable among fields of science for two reasons: (i) each field has a different impact maturity time, and (ii) because of systematic differences in publication and citation behaviour across disciplines. In fact, the 5-JIF firstly appeared in the Journal Citation Reports (JCR) in 2007 with the purpose of making more comparable impacts in fields in which impact matures slowly. However, there is not an optimal fixed impact maturity time valid for all the fields. In some of them two years provides a good performance whereas in others three or more years are...

    2012-01-01

    Citation analysis of documents retrieved from the Medline database (at the Web of Knowledge) has been possible only on a case-by-case basis. A technique is here developed for citation analysis in batch mode using both Medical Subject Headings (MeSH) at the Web of Knowledge and the Science Citation Index at the Web of Science. This freeware routine is applied to the case of "Brugada Syndrome," a specific disease and field of research (since 1992). The journals containing these publications are attributed to Web-of-Science Categories other than "Cardiac and Cardiovascular Systems"), perhaps because of the possibility of genetic testing for this syndrome in the clinic. With this routine, all the instruments available for citation analysis can be used on the basis of MeSH terms.

  14. Citation analysis of meta-analysis articles on posttraumatic stress disorder

    Institute of Scientific and Technical Information of China (English)

    LIAO Xi-ming; CHEN Ping-yan

    2011-01-01

    Background In the past two decades enormously scientific researches on posttraumatic stress disorder (PTSD) have been undertaken and many related meta-analyses have been published. Citation analysis was used to get comprehensive perspectives of meta-analysis articles (MA articles) on PTSD for the purpose of facilitating the researchers,physicians and policy-makers to understand the PTSD.Methods MA articles on PTSD in any languages from January 1980 to March 2009 were included if they presented meta-analytical methods and received at least one citation recorded in the Web of Science (WoS). Whereas studies,in which any effect sizes of PTSD were not distinguished from other psychological disorders,were excluded. Citations to and by identified MA articles were documented basing on records in WoS. Citation analysis was used to examine distribution patterns of characteristics and citation impact of MA articles on PTSD. Canonical analysis was used to explore the relationship between the characteristics of MA articles and citation impact.Results Thirty-four MA articles published during 1998 and 2008 were identified and revealed multiple study topics on PTSD:10 (29.4%) were about epidemiology,13 (38.2%) about treatment or intervention,6 (17.6%) about pathophysiology or neurophysiology or neuroendocrine,3 (8.8%) about childhood and 2 (5.9%) about psychosocial adversity. Two articles cited most frequently with 456 and 145 counts were published in Journal of Consulting and Clinical Psychology by Brewin (2000) and Psychological Bulletin by Ozer (2003),respectively. Mean cited count was 7.48±10.56and mean age (year 2009 minus article publication year) was (4.24±2.91) years. They had been cited approximately by 67 disciplines and by authors from 42 countries or territories. Characteristics of meta-analysis highly correlated with citation impact and reflected by canonical correlation of 0.899 (P <0.000 01).Conclusions The age of MA articles predicted their citation impact

    In this paper we present a phenomenological approach to describe a complex system: scientific research impact through Citation Mining. The novel concept of Citation Mining, a combination of citation bibliometrics and text mining, is used for the phenomenological description. Citation Mining starts with a group of core papers whose impact is to be examined, retrieves the papers that cite these core papers, and then analyzes the technical infrastructure (authors, jorunals, institutions) of the citing papers as well as their thematic characteristics.

  18. New model for datasets citation and extraction reproducibility in VAMDC

    CERN Document Server

    Zwölf, Carlo Maria; Dubernet, Marie-Lise

    2016-01-01

    In this paper we present a new paradigm for the identification of datasets extracted from the Virtual Atomic and Molecular Data Centre (VAMDC) e-science infrastructure. Such identification includes information on the origin and version of the datasets, references associated to individual data in the datasets, as well as timestamps linked to the extraction procedure. This paradigm is described through the modifications of the language used to exchange data within the VAMDC and through the services that will implement those modifications. This new paradigm should enforce traceability of datasets, favour reproducibility of datasets extraction, and facilitate the systematic citation of the authors having originally measured and/or calculated the extracted atomic and molecular data.

  19. Network-based statistical comparison of citation topology of bibliographic databases.

    2014-01-01

    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, while, not surprisingly, Web of Science is significantly more reliable from the perspective of consistency. This work can serve either as a reference for scholars in bibliometrics and scientometrics or a scientific evaluation guideline for governments and research agencies. PMID:25263231

    Science.gov (United States)

    Lu, Dominic P

    2013-01-01

    I-Ching or Yi-Jing ([see text] also known as The Book of Changes) is the earliest classic in China. It simply explained the formation of the universe and the relationship of man to the universe. Most, if not all, branches of various knowledge, including traditional Chinese medicine, can be traced back its origin to this Book in which Fu Shi ([see text] 2852 B.C.) theorized how the universe was formed, through his keen observation of environment and orbits of sun, moon and stars. He used symbols to represent his views. The essence of I-Ching is basically the expression and function of Yang symbolized as "--" (from ) and Yin symbolized "- -" (from -->universe as what it is. Yang and Yin manifest in great variety of phenomena such as mind and body, masculine and feminine, sun and moon, hot and cold, heaven and earth, positive and negative electricity etc. The entire theory of Chinese medicine is based on the theories of Yin and Yang as well as that of 5 Element Cycles which are also related to the orderly arrangement of 8 trigrams ([see text]) by King Wen ([see text]1099-1050 B.C.). The 5 Elements Theory explains the "check and balance" mechanism created by the background force of Yin and Yang Qi and illustrated the relationships that are either strengthened or weakened by "acting and controlling" among the 5 elements. I-Ching has exerted profound influences on some well- known European philosophers and scientists, notably Leibnitz and Hegel. Between I-Ching and modern cosmology and the physics of sub-atomic particles, there are some basic theories in common. PMID:23724698

These indexes are arranged alphabetically and cross-referenced by page number.

  8. Patterns of database citation in articles and patents indicate long-term scientific and industry value of biological data resources [version 1; referees: 2 approved

    Directory of Open Access Journals (Sweden)

    David Bousfield

    2016-02-01

    Full Text Available 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.

    Full Text Available A challenge in teaching English composition is helping students envision plagiarism as “borrowing” – showing love to author(s and/or text(s that further their argument(s, versus “stealing” – biting someone’s style and words. Alastair Pennycook (1996 and Sarah Wakefield (2006 have contributed pieces to the elaborate plagiarism/citation puzzle, while Houston Baker situated the hip-hop DJ in seminal text Black Studies, Rap and the Academy (1993. Merging these moments introduces critical questions: Did Diddy invent “the remix” or become the illest beat-biter ever? How did DJ/Producers Pete Rock and Large Professor pay homage to previous musical genres to further hip-hop remix production without just taking 4-8 bar samples, copying sources and claiming unethical ownership? And how can this discussion provide students a window into citation conversations? This article will remix these “texts” to introduce the idea of DJ Rhetoric to discuss plagiarism. Through the lens of the hip-hop DJ in writing classrooms, one can foster an appreciation of the difference between “love and theft” in student citation. This article will couple examples from hip-hop music/culture while simultaneously remixing interviews from various hip-hop DJ/producers to help answer these difficult questions.

  13. Universal hierarchical behavior of citation networks

    International Nuclear Information System (INIS)

    Many of the essential features of the evolution of scientific research are imprinted in the structure of citation networks. Connections in these networks imply information about the transfer of knowledge among papers, or, in other words, edges describe the impact of papers on other publications. This inherent meaning of the edges implies that citation networks can exhibit hierarchical features that are typical of networks based on decision making. In this paper, we investigate the hierarchical structure of citation networks consisting of papers in the same field. We find that the majority of the networks follow a universal trend towards a highly hierarchical state, and the various fields display differences only concerning (i) their phase in life (distance from the ‘birth’ of a field) or (ii) the characteristic time according to which they are approaching the stationary state. We also show by a simple argument that the alterations in the behavior are related to and can be understood by the degree of specialization corresponding to the fields. Our results suggest that during the accumulation of knowledge in a given field, some papers are gradually becoming relatively more influential than most other papers. (paper)

  17. Longitudinal study on patent citations to academic research articles in nanotechnology (1976-2004)

    International Nuclear Information System (INIS)

    Academic nanoscale science and engineering (NSE) research provides a foundation for nanotechnology innovation reflected in patents. About 60% or about 50,000 of the NSE-related patents identified by 'full-text' keyword searching between 1976 and 2004 at the United States Patent and Trademark Office (USPTO) have an average of approximately 18 academic citations. The most cited academic journals, individual researchers, and research articles have been evaluated as sources of technology innovation in the NSE area over the 28-year period. Each of the most influential articles was cited about 90 times on the average, while the most influential author was cited more than 700 times by the NSE-related patents. Thirteen mainstream journals accounted for about 20% of all citations. Science, Nature and Proceedings of the National Academy of Sciences (PNAS) have consistently been the top three most cited journals, with each article being cited three times on average. There is another kind of influential journals, represented by Biosystems and Origin of Life, which have very few articles cited but with exceptionally high frequencies. The number of academic citations per year from ten most cited journals has increased by over 17 times in the interval (1990-1999) as compared to (1976-1989), and again over 3 times in the interval (2000-2004) as compared to (1990-1999). This is an indication of increased used of academic knowledge creation in the NSE-related patents

    Identifiers for data are the bedrock on which data citation and publication rests. These, in their turn, are widely proposed as methods for encouraging researchers to share their datasets, and at the same time receive academic credit for their efforts in producing them. However, neither data citation nor publication can be properly achieved without a method of identifying clearly what is, and what isn't, part of the dataset. Once a dataset becomes part of the scientific record (either through formal data publication or through being cited) then issues such as dataset stability and permanence become vital to address. In the geosciences, several projects in the UK are concentrating on issues of dataset identification, citation and publication. The UK's Natural Environment Research Council's (NERC) Science Information Strategy data citation and publication project is addressing the issue of identifiers for data, stability, transparency, and credit for data producers through data citation. At a data publication level, 2012 has seen the launch of the new Wiley title Geoscience Data Journal and the PREPARDE (Peer Review for Publication & Accreditation of Research Data in the Earth sciences) project, both aiming to encourage data publication by addressing issues such as data paper submission workflows and the scientific peer-review of data. All of these initiatives work with a range of partners including academic institutions, learned societies, data centers and commercial publishers, both nationally and internationally, with a cross-project aim of developing the mechanisms so data can be identified, cited and published with confidence. This involves investigating barriers and drivers to data publishing and sharing, peer review, and re-use of geoscientific datasets, and specifically such topics as dataset requirements for citation, workflows for dataset ingestion into data centers and publishers, procedures and policies for editors, reviewers and authors of data

    One is inclined to conceptualize impact in terms of citations per publication, and thus as an average. 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 WoS Subject Category of "Nanoscience & nanotechnology," and rank journals, countries, cities, and institutes using non-parametric statistics. The significance levels of results can thus be indicated. The results are first compared with the ISI-impact factors, but this Integrated Impact Indicator (I3) can be used with any set downloaded from the (Social) Science Citation Index. The software is made publicly available at the Internet. Visualization techniques are also specified for evaluation by positioning institutes on Google Map overlays. PMID:23293403

  2. Co-word Analysis using the Chinese Character Set

    Leydesdorff, Loet

    2009-01-01

    Until recently, Chinese texts could not be studied using co-word analysis because the words are not separated by spaces in Chinese (and Japanese). A word can be composed of one or more characters. The online availability of programs that separate Chinese texts makes it possible to analyze them using semantic maps. Chinese characters contain not only information, but also meaning. This may enhance the readability of semantic maps. In this study, we analyze 58 words which occur ten or more times in the 1652 journal titles of the China Scientific and Technical Papers and Citations Database. The word occurrence matrix is visualized and factor-analyzed.

    SAEON operates a shared research data infrastructure for its own data sets and for clients and end users in the Earth and Environmental Sciences domain. SAEON has a license to issue Digital Object Identifiers via DataCite on behalf of third parties, and have recently concluded development work to make a universal data deposit, description, and DOI minting facility available. This facility will be used to develop a number of end user gateways, including DataCite South Africa (in collaboration with National Research Foundation and addressing all grant-funded research in the country), DIRISA (Data-intensive Research Infrastructure for South Africa - in collaboration with Meraka Institute and Department of Science and Technology), and SASDI (South African Spatial Data Infrastructure). The RDA recently published Data Citation Recommendations [1], and this was used as a basis for specification of Digital Object Identifier implementation, raising two significant challenges: 1. Synchronisation of frequently harvested meta-data sets where version management practice did not align with the RDA recommendations, and 2. Handling sub-sets of and queries on large, continuously updated data sets. In the first case, we have developed a set of tests that determine the logical course of action when discrepancies are found during synchronization, and we have incorporated these into meta-data harvester configurations. Additionally, we have developed a state diagram and attendant workflow for meta-data that includes problem states emanating from DOI management, reporting services for data depositors, and feedback to end users in respect of synchronisation issues. In the second case, in the absence of firm guidelines from DataCite, we are seeking community consensus and feedback on an approach that caches all queries performed and subsets derived from data, and provide these with anchor-style extensions linked to the dataset's original DOI. This allows extended DOIs to resolve to a meta

    ABSTRACT Objective: to identify and synthesize the evidence from randomized clinical trials that tested the effectiveness of traditional Chinese acupuncture in relation to sham acupuncture for the treatment of hot flashes in menopausal women with breast cancer. Method: systematic review guided by the recommendations of the Cochrane Collaboration. Citations were searched in the following databases: MEDLINE via PubMed, Web of Science, CENTRAL, CINAHL, and LILACS. A combination of the following keywords was used: breast neoplasm, acupuncture, acupuncture therapy, acupuncture points, placebos, sham treatment, hot flashes, hot flushes, menopause, climacteric, and vasomotor symptoms. Results: a total of 272 studies were identified, five of which were selected and analyzed. Slight superiority of traditional acupuncture compared with sham acupuncture was observed; however, there were no strong statistical associations. Conclusions: the evidence gathered was not sufficient to affirm the effectiveness of traditional acupuncture compared with sham acupuncture. PMID:27533271

    Bornmann, Lutz; Barth, Andreas

    2013-01-01

    If we want to assess whether the paper in question has had a particularly high or low citation impact compared to other papers, the standard practice in bibliometrics is to normalize citations in respect of the subject category and publication year. A number of proposals for an improved procedure in the normalization of citation impact have been put forward in recent years. Against the background of these proposals this study describes an ideal solution for the normalization of citation impact: in a first step, the reference set for the publication in question is collated by means of a classification scheme, where every publication is associated with a single principal research field or subfield entry (e. g. via Chemical Abstracts sections) and a publication year. In a second step, percentiles of citation counts are calculated for this set and used to assign the normalized citation impact score to the publications (and also to the publication in question).

    Mark-and-Recapture is a methodology from Population Biology to estimate the number of a species without counting every individual. This is done by multiple samplings of the species using traps and discounting the instances that were caught repeated. In this paper we show that this methodology is applicable for citation analysis as it is also not feasible to count all the relevant publications of a research topic. In addition this estimation also allows us to propose a stopping rule for researchers to decide how far one should extend their search for relevant literature.

  13. Link Label Prediction in Signed Citation Network

    KAUST Repository

    Akujuobi, Uchenna

    2016-04-12

    Link label prediction is the problem of predicting the missing labels or signs of all the unlabeled edges in a network. For signed networks, these labels can either be positive or negative. In recent years, different algorithms have been proposed such as using regression, trust propagation and matrix factorization. These approaches have tried to solve the problem of link label prediction by using ideas from social theories, where most of them predict a single missing label given that labels of other edges are known. However, in most real-world social graphs, the number of labeled edges is usually less than that of unlabeled edges. Therefore, predicting a single edge label at a time would require multiple runs and is more computationally demanding. In this thesis, we look at link label prediction problem on a signed citation network with missing edge labels. Our citation network consists of papers from three major machine learning and data mining conferences together with their references, and edges showing the relationship between them. An edge in our network is labeled either positive (dataset relevant) if the reference is based on the dataset used in the paper or negative otherwise. We present three approaches to predict the missing labels. The first approach converts the label prediction problem into a standard classification problem. We then, generate a set of features for each edge and then adopt Support Vector Machines in solving the classification problem. For the second approach, we formalize the graph such that the edges are represented as nodes with links showing similarities between them. We then adopt a label propagation method to propagate the labels on known nodes to those with unknown labels. In the third approach, we adopt a PageRank approach where we rank the nodes according to the number of incoming positive and negative edges, after which we set a threshold. Based on the ranks, we can infer an edge would be positive if it goes a node above the

    In this work we have studied the research activity for countries of Europe, Latin America and Africa for all sciences between 1945 and November 2008. All the data are captured from the Web of Science database during this period. The analysis of the experimental data shows that, within a nonextensive thermostatistical formalism, the Tsallis \\emph{q}-exponential distribution $N(c)$ satisfactorily describes Institute of Scientific Information citations. The data which are examined in the present survey can be fitted successfully as a first approach by applying a {\\it single} curve (namely, $N(c) \\propto 1/[1+(q-1) c/T]^{\\frac{1}{q-1}}$ with $q\\simeq 4/3$ for {\\it all} the available citations $c$, $T$ being an "effective temperature".

    This paper focuses on measuring the academic research performance of Chinese universities by using Scopus database from 2007 to 2010. We have provided meaningful indicators to measure the research performance of Chinese universities as compared to world class universities of the US and the European region. Using these indicators, we first measure the quantity and quality of the research outcomes of the universities and then examine the internationalization of research by using international collaborations, international citations and international impact metrics. Using all of this data, we finally present an overall score called research performance point to measure the comprehensive research strength of the universities for the selected subject categories. The comparison identifies the gap between Chinese universities and top-tier universities from selected regions across various subject areas. We find that Chinese universities are doing well in terms of publication volume but receive less citations from their published work. We also find that the Chinese universities have relative low percentage of publications at high impact venues, which may be the reason that they are not receiving more citations. Therefore, a careful selection of publication venues may help the Chinese universities to compete with world class universities and increase their research internationalization. © 2014 Akadémiai Kiadó, Budapest, Hungary.

    Do you write code for your research? Use astronomical software? Do you wish there were a better way of citing, sharing, archiving, or discovering software for astronomy research? You're not alone! In April 2015, AAS's publishing team joined other leaders in the astronomical software community in a meeting funded by the Sloan Foundation, with the purpose of discussing these issues and potential solutions. In attendance were representatives from academic astronomy, publishing, libraries, for-profit software sharing platforms, telescope facilities, and grantmaking institutions. The goal of the group was to establish “protocols, policies, and platforms for astronomical software citation, sharing, and archiving,” in the hopes of encouraging a set of normalized standards across the field. The AAS is now collaborating with leaders at GitHub to write grant proposals for a project to develop strategies for software discoverability and citation, in astronomy and beyond. If this topic interests you, you can find more details in this document released by the group after the meeting: http://astronomy-software-index.github.io/2015-workshop/ The group hopes to move this project forward with input and support from the broader community.

    Impact factors (and similar measures such as the Scimago Journal Rankings) suffer from two problems: (i) citation behavior varies among fields of science and therefore leads to systematic differences, and (ii) there are no statistics to inform us whether differences are significant. The recently introduced SNIP indicator of Scopus tries to remedy the first of these two problems, but a number of normalization decisions are involved which makes it impossible to test for significance. Using fractional counting of citations-based on the assumption that impact is proportionate to the number of references in the citing documents-citations can be contextualized at the paper level and aggregated impacts of sets can be tested for their significance. It can be shown that the weighted impact of Annals of Mathematics (0.247) is not so much lower than that of Molecular Cell (0.386) despite a five-fold difference between their impact factors (2.793 and 13.156, respectively).

  6. Engineering education research in European Journal of Engineering Education and Journal of Engineering Education: citation and reference discipline analysis

    Wankat, Phillip C.; Williams, Bill; Neto, Pedro

    2014-01-01

    The authors, citations and content of European Journal of Engineering Education (EJEE) and Journal of Engineering Education (JEE) in 1973 (JEE, 1975 EJEE), 1983, 1993, 2003, and available 2013 issues were analysed. Both journals transitioned from house organs to become engineering education research (EER) journals, although JEE transitioned first. In this process the number of citations rose, particularly of education and psychology sources; the percentage of research articles increased markedly as did the number of reference disciplines. The number of papers per issue, the number of single author papers, and the citations of science and engineering sources decreased. EJEE has a very broad geographic spread of authors while JEE authors are mainly US based. A 'silo' mentality where general engineering education researchers do not communicate with EER researchers in different engineering disciplines is evident. There is some danger that EER may develop into a silo that does not communicate with technically oriented engineering professors.

    Acta Dermatovenerologica Alpina, Pannonica et Adriatica is small regional professional journal that started publishing in 1992. Despite the journal's relatively narrow readership, it has significantly improved its quality and global profile during the last 20 years, as shown in this citation analysis update. Since 1992, 654 bibliographical items have been published. Among these, 545 (83.4%) were considered WoS citable items and 109 (16.6%) WoS noncitable items. Since 2008, 90% of all published items have been considered WoS citable items and received an average of 1.9 citations per item. The predicted Acta Dermatovenerol APA impact factor calculated using data from a Cited Reference search of Thomson Scientific's Web of Science has shown steep and continuous increase since 2006, when the journal acquired full indexing status in Index Medicus/Medline, and has been above 0.5 since 2008.

  12. Maps on the basis of the Arts & Humanities Citation Index: The journals Leonardo and Art Journal versus "Digital Humanities" as a topic

    CERN Document Server

    Leydesdorff, Loet

    2009-01-01

    The possibilities of using the Arts & Humanities Citation Index (A&HCI) for journal mapping have not been sufficiently recognized because of the absence of a Journal Citations Report (JCR) for this database. A quasi-JCR for the A&HCI (2008) was constructed from the data contained in the Web-of-Science and is used for the evaluation of two journals as examples: Leonardo and Art Journal. The maps on the basis of the aggregated journal-journal citations within this domain can be compared with maps including references to journals in the Science Citation Index and Social Science Citation Index. Art journals are cited by (social) science journals more than by other art journals, but these journals draw upon one another in terms of their own references. This cultural impact in terms of being cited is not found when documents with a topic such as "digital humanities" are analyzed. This community of practice functions more as an intellectual organizer than a journal.

    Scientific achievement by publishing a scientific manuscript in a peer reviewed biomedical journal is an important ingredient of research along with a career-enhancing advantages and significant amount of personal satisfaction. The road to evaluate science (research, scientific publications) among scientists often seems complicated. Scientist's career is generally summarized by the number of publications / citations, teaching the undergraduate, graduate and post-doctoral students, writing or reviewing grants and papers, preparing for and organizing meetings, participating in collaborations and conferences, advising colleagues, and serving on editorial boards of scientific journals. Scientists have been sizing up their colleagues since science began. Scientometricians have invented a wide variety of algorithms called science metrics to evaluate science. Many of the science metrics are even unknown to the everyday scientist. Unfortunately, there is no all-in-one metric. Each of them has its own strength, limitation and scope. Some of them are mistakenly applied to evaluate individuals, and each is surrounded by a cloud of variants designed to help them apply across different scientific fields or different career stages [1]. A suitable indicator should be chosen by considering the purpose of the evaluation, and how the results will be used. Scientific Evaluation assists us in: computing the research performance, comparison with peers, forecasting the growth, identifying the excellence in research, citation ranking, finding the influence of research, measuring the productivity, making policy decisions, securing funds for research and spotting trends. Key concepts in science metrics are output and impact. Evaluation of science is traditionally expressed in terms of citation counts. Although most of the science metrics are based on citation counts but two most commonly used are impact factor [2] and h-index [3]. PMID:27493300

    The rise of modern American scholarship on China was largely attributed to the establishment of the American Joint Committee on Contemporary China (JCCC) in 1959 which sponsored all kinds of activities to promote Chinese studies, ranging from institutional support and financial resources to training courses. Since then, American study of China has entered into a period of sustainability that features academic and group-oriented research. It has become a mainstream discipline in American social science studies.1 There are some distinctive differences between early sinology and modern Chinese Studies: the latter is much more concentrated on the study of issues, comparative historical studies, and contemporary Chinese society. American Chinese studies stresses empirical research, textual data, and the application of theory to practice.Shanghai.
