Language: English Document Type: Article Abstract: Converging research is the emergence of new interdisciplinary research from fields which showed limited mutual interdisciplinary connections before. We describe three search strategies to identify converging research using data extracted from the WoS, including the social sciences and humanities. The field-to-field references (FFR) strategy uses citations from one journal subject category (JSC), to another; the keyword sets (KWS) strategy tracks the co-occurrence of keywords from different JSCs; and the affiliation patterns (AFP) strategy traces the co-occurrence of fields of research in author affiliations of papers. Resulting publication sets were assessed using data such as journal names, titles of publications, and titles of cited publications. Experts validated nine converging research areas that were detected using the KWS and FFR strategies; none were found with AFT strategy. Addresses: [Buter, Reindert K.; Noyons, Ed C.

Author Full Name(s): Lariviere, Vincent; Macaluso, Benoit; Archambault, Eric; Gingras, Yves Language: English Document Type: Article Abstract: Using the population of all university professors (N = 13,479) in the province of Quebec, Canada, this article analyses the concentration of funding, papers and citations at the level of individual researchers. It shows that each of these distributions is different, citations being the most concentrated followed by funding, papers published and, finally, number of funded projects. Concentration measures also vary between disciplines; social sciences and humanities generally being the most concentrated. The article also shows that the correspondence between the elites defined by each of these measures is limited. In fact, only 3.2% of the researchers are in the top 10% for all indicators, while about 20% are in the top 10% for at least one of the indicators. The article concludes with a discussion of the causes of these observed differences and formulates a few hypotheses.

Author Full Name(s): Torres-Salinas, Daniel; Jimenez-Contreras, Evaristo Language: Spanish Document Type: Article Abstract: The evaluation of scientific journals with bibliometric indicators has been dominated by the Impact factor since the 70s. However Thomson has recently included in the Journal Citation Reports the Eigen factor and the Article influence score. On the other hand Elsevier has included in Scopus the Source normalized impact per paper (SNIP) and the SCImago journal rank (SJR). In this paper we introduce, and describe these indicators. Secondly to study the similarities we analyze correlations of the traditional indicators and the new ones, detailing the results across 27 scientific fields. It was noted that some couples of indicators such as Eigen Citations, Impact factor-ArticleScore, Impact factor SJR and SJR-ArticleScore do correlate in many areas. Correlations showed different trends in Science and Social science; therefore, in the last section we discuss the need to take into account the scientific area when selecting an indicator.

The Citation Relationships between Journals of Geography and Cognate Disciplines. GEOGRAPHICAL RESEARCH 48 (2): 166-180 Author Full Name(s): Laffan, Shawn W. Language: English Document Type: Article Abstract: There is an ongoing debate concerning the relationship between the disciplinary ends of the broad spectrum that is geography and also the relationship between geography and other disciplines, including the extent to which it is self-focussed or inward looking. These issues were assessed using an analysis of citation relationships between journals in the Thompson Scientific Journal Citation Reports databases at the category level. Thirty-four categories were used, comparing the two geography categories ('Geography', representing human geography and 'Geography, Physical', representing physical geography) with 32 other cognate categories. A matrix of the citation relationships between each category was developed using a relatedness factor that corrects for the opportunity for citations to occur. The resultant matrix of factors indicates that human geography journals are considerably more likely to cite their own papers than are those of physical geography, but that they are by no means the most self-citing of the journals assessed. Both human and physical geography journals have strong citation relationships with several other disciplines, with those for human geography most often being net export relationships in the sense of a balance of trade. This finding contradicts previous assertions that human geography imports more than it exports. The citation relationships of physical geography are smaller than those of human geography, and are typically small net imports. The relationship between human and physical geography journals is a small net export from physical geography to human geography, but their total trade volume is considerably smaller than their respective relationships with other disciplines. These results are likely to be caused by many factors in addition to the actual relatedness between disciplines and sub-disciplines, but they do represent a benchmark against which more detailed analyses can be assessed.

Author Full Name(s): Swanepoel, Adriaan Language: English Document Type: Proceedings Paper Abstract: A longitudinal study at the Tshwane University of Technology (TUT) used citation analysis to analyze the reference lists of 480 master's and doctoral (M and D) theses and dissertations submitted at TUT between 2004 and 2007. The purpose was to determine what types of information sources M and D students at TUT use most, how the patterns of use differ across the seven faculties of the university, and to what extent the Library and Information Services (LIS) keeps or provides access to the journals that are mostly used by M and D students. More than 37 000 citations were analyzed over the four-year period. The study found several similarities but also some distinct differences in the use of information sources across the seven faculties of TUT. It also identified more than 60 different information sources used by M and D students. With regard to journal use, the study found that out of 3 641 different journals cited, most journals were only cited once over a period of four years. However, a small percentage of journals were highly and/or frequently cited. Keywords: Citation analysis; Theses and dissertations.

Prestige and impact Archives of Budo for scientific research of the martial arts. ARCHIVES OF BUDO 6 (1): Author Full Name(s): Kalina, Roman Maciej; Barczynski, Bartlomiej Jan Language: English Document Type: Editorial Material Abstract: Archives of Budo after nearly five years since the first article appeared (2005) has been included for coverage in the Thomson Reuters- Science Citation Index Expanded focus on: Sports Science & Medicine. The unique value Archives of Budo (mainly depends on the fact that annually the journal accumulates at the most scientific articles of martial arts) proves that despite the large number of downloads of individual articles, there are few citations of these papers recorded by the Journal Citation Report. The fact that in any other journal of Sports Science & Medicine evaluated by Thomson Reuters in which appears annually as many publications on the martial arts as at Archives of Budo is proof that only a few scientists engaged in this issue. The term "budo" in the title of the journal is used in a broad sense, because it is addressed to "the global reader". We mean well-educated people from different parts of the world who read scientific publications. Probably many, if not most, associate "budo" with the specific martial arts regardless of the origin (i.e. with the Japanese judo, Chinese kunk fu, Korean taekwondo, Brazilian capoeira, the Israeli kravmaga etc). Anyone who deals with budo in the strict meaning (combined with tradition and culture of Japan) we encourage to study book Budo: The Martial Ways of Japan.

Equations for quantifying contextual cocitation strength are introduced and their implications explored using theoretical examples alongside the application of contextual cocitation to a series of BioMed Central publications and their cited resources. Based on this work, the implications of contextual cocitation for understanding the granularity of the relationships created between cited published research and methods for its analysis are discussed. Future applications and improvements of this work, including its extended application to the published research of multiple disciplines, are then presented with rationales for their inclusion.

Author Full Name(s): Abramo, Giovanni; D'Angelo, Ciriaco Andrea; Viel, Fulvio Language: English Document Type: Article Abstract: The use of Hirsch's h-index as a joint proxy of the impact and productivity of a scientist's research work continues to gain ground, accompanied by the efforts of bibliometrists to resolve some of its critical issues through the application of a number of more or less sophisticated variants. However, the literature does not reveal any appreciable attempt to overcome the objective problems of measuring h-indexes on a large scale for purposes of comparative evaluation. Scientists may succeed in calculating their own h-indexes but, being unable to compare them to those of their peers, they are unable to obtain truly useful indications of their individual research performance. This study proposes to overcome this gap, measuring the h- and Egghe's g-indexes of all Italian university researchers in the hard sciences over a 5-year window. Descriptive statistics are provided concerning all of the 165 subject fields examined, offering robust benchmarks for those who wish to compare their individual performance to those of their colleagues in the same subject field.

CONSERVATION BIOLOGY 24 (3): 872-880 Author Full Name(s): Calver, Michael C.; Bradley, J. Stuart Language: English Document Type: Article Abstract: Open access (OA) publishing, whereby authors, their institutions, or their granting bodies pay or provide a repository through which peer-reviewed work is available online for free, is championed as a model to increase the number of citations per paper and disseminate results widely, especially to researchers in developing countries. We compared the number of citations of OA and non-OA papers in six journals and four books published since 2000 to test whether OA increases number of citations overall and increases citations made by authors in developing countries. After controlling for type of paper (e. g., review or research paper), length of paper, authors' citation profiles, number of authors per paper, and whether the author or the publisher released the paper in OA, OA had no statistically significant influence on the overall number of citations per journal paper. Journal papers were cited more frequently if the authors had published highly cited papers previously, were members of large teams of authors, or published relatively long papers, but papers were not cited more frequently if they were published in an OA source. Nevertheless, author-archived OA book chapters accrued up to eight times more citations than chapters in the same book that were not available through OA, perhaps because there is no online abstracting service for book chapters. There was also little evidence that journal papers or book chapters published in OA received more citations from authors in developing countries relative to those journal papers or book chapters not published in OA. For scholarly publications in conservation biology, only book chapters had an OA citation advantage, and OA did not increase the number of citations papers or chapters received from authors in developing countries.

Moreover, there are concerns as the JIF is often used as a comparison for journals from different disciplines. In this study, the JIF computation of eight top ranked journals from four different subject categories was analyzed. The analysis reveals that most of the published items (> 65%) in the science disciplines were nonresearch items while fewer such items (< 22%) were observed in engineering-based journals. The single regression analysis confirmed that there is correlation (R-2 >= .99) in the number of published items or citations received over the two-year period used in the JIF calculation amongst the eight selected journals. A weighted factor computation is introduced to compensate for the smaller journals and journals that publish longer turnover research. It is hoped that the approach can provide a comprehensive assessment of the quality of a journal regardless of the disciplinary field.

The establishment of specialized scholarly journals facilitates the formation of such communities or networks. Publications, especially articles in specialized journals, have become institutionalized as the 'ultimate' form of scientific communication. Specialized journals fulfil a key role in the scientific disciplines. They both secure the shared values of a scientific community and endorse what that community takes to be certified knowledge. This article first elaborates on the evolution of communication within scientific disciplines. Afterwards, it presents an analysis of publication practices in the main generalist sociology journals in the Low Countries. Because of the close relationship between journals and discipline, this sociological analysis addresses the evolution of sociology itself.

As North American-based scholars with European ties, we decided to examine the impact of Organization Studies in North American academia with the objective of understanding what, if anything, makes some Organization Studies articles more likely to have impact in North America than others. To set the stage for better understanding the role of Organization Studies in this academic community, we first present the key characteristics of North American academia. Secondly, relying on archival data spanning the first 29 years of Organization Studies (1980 to 2008, inclusive), we identify an apparent dynamic of select re- importation of exported ideas. Put otherwise, top North American journals tend to re-import ideas authored (and exported) by select North American scholars in Organizations Studies. Thirdly, we discuss the implications of this process on the field of organization studies and on the circulation of ideas across academic communities.

Omran published his classic paper on the theory of epidemiologic transition. By the mid-1990s, it had become something of a citation classic and was understood as a theoretical statement about the shift from infectious to chronic diseases that supposedly accompanies modernization. However, Omran himself was not directly concerned with the rise of chronic disease; his theory was in fact closely tied to efforts to accelerate fertility decline through health-oriented population control programs. This article uses Omran's extensive published writings as well as primary and secondary sources on population and family planning to place Omran's career in context and reinterpret his theory. We find that "epidemiologic transition" was part of a broader effort to reorient American and international health institutions towards the pervasive population control agenda of the 1960s and 1970s. The theory was integral to the WHO's then controversial efforts to align family planning with health services, as well as to Omran's unsuccessful attempt to create a new sub-discipline of "population epidemiology." However, Omran's theory failed to displace demographic transition theory as the guiding framework for population control. It was mostly overlooked until the early 1990s, when it belatedly became associated with the rise of chronic disease.

This article discusses the two most relevant methods for creating a ranking of persons as well as their opportunities and shortcomings. From a conceptual point of view citation based rankings seem to be more appropriate than those based on journals. Against the background of this the methodology of the Handelsblatt-BWL-Ranking will be critically assessed. A comparative study shows that a citation based ranking on the basis of Google Scholar leads to completely different results. The citations, the publications of a scientist accumulate, do not predict his position in the Handelsblatt-BWL-Ranking. With that results in mind rankings of persons should be interpreted only with great caution.

In other words, under what circumstances do initial status differences result in highly skewed reward distributions over the long run, and when, conversely, is the accumulation of status-based advantages constrained? Using a formal model, we investigate the fates of actors in a contest who start off as status- equivalents, produce at different levels of quality, and thus come to occupy distinct locations in a status ordering. We build from a set of equations in which failing to observe cumulative advantage seems implausible and then demonstrate that, despite initial conditions designed to lead inevitably to status monopolization, circumstances still exist that rein in the Matthew Effect. Our results highlight the importance of a single factor governing whether the Matthew Effect operates freely or is circumscribed. This factor is the degree to which status diffuses through social relations. When actors' status levels are strongly influenced by the status levels of those dispensing recognition to them, then eventually the top-ranked actor is nearly matched in status by the lower-ranked actor she endorses. In contrast, when actors' status levels are unaffected by the status levels of those giving them recognition, the top- ranked actor amasses virtually all status available in the system. Our primary contribution is the intuition that elites may unwittingly and paradoxically destroy their cumulative advantage beneath the weight of their endorsements of others. Consequently, we find that the Matthew Effect is curtailed by a process that, at least in some social settings, is a property of status itselfits propensity to diffuse through social relations. Implications for future research are discussed.

Study Design and Setting: In this cohort study, citation counts were retrieved for articles describing consensus statements that were published in multiple journals and were correlated with the impact factors of the source journals. Results: Four consensus statements were published in multiple copies: QUOROM (QUality Of Reporting Of Meta-analyses) was published in three journals, CONSORT (CONsolidated Standards Of Reporting Trials) in eight journals, STARD (STAndards for Reporting of Diagnostic accuracy) in 14 journals, and STROBE (STrengthening the Reporting of OBservational studies in Epidemiology) in eight journals. For each consensus statement, the impact factor of the source journal and the number of citations were highly correlated (Spearman correlation coefficients: QUOROM, 1.00; CONSORT, 0.88; STARD, 0.65; and STROBE, 0.81-all P < 0.02). When adjusted for time since publication, each logarithm unit of impact factor predicted an increase of 1.0 logarithm unit of citations (95% confidence interval: 0.7-1.3, P < 0.001), and the variance explained was 66% (adjusted r(2) = 0.66). Conclusions: The prominence of the journal where an article is published, measured by its impact factor, influences the number of citations that the article will gather over time. Citation counts are not purely a reflection of scientific merit. (C) 2010 Elsevier Inc. All rights reserved.

Author Full Name(s): Small, Henry Language: English Document Type: Article Author Keywords: Interdisciplinarity; Maps of science; Co-citation contexts; Analogy; Cue word analysis KeyWords Plus: CITATION; SIMULATION; CLUSTERS Abstract: Interdisciplinarity can be manifest in many forms: through collaboration or communication between scientists working in different fields or through the work of individual scientists who employ concepts or methods across disciplines. This latter form of interdisciplinarity is addressed here with the goal of understanding how ideas in different fields come together to create new opportunities for discovery. Maps of science are used to suggest possible interdisciplinary links which are then analyzed by co-citation context analysis. Interdisciplinary links are identified by juxtaposing a clustering and mapping of documents against a journal-based categorization of the same document clusters. Links between clusters are characterized as interdisciplinary based on the dissonance of their category assignments. To verify and probe more deeply into the meaning of interdisciplinary links, co-citation contexts for selected links from five separate cases are analyzed in terms of prominent cue words. This analysis reveals that interdisciplinary connections are often based on authors' perceptions of analogous problems across scientific domains. Cue words drawn from the citation contexts also suggest that these connections are viewed as important and ripe with both opportunity and risk.

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

However, Schumpeter is receiving increasing attention from mainstream economists. A few specific examples are discussed, and the citation time series for Keynes and Schumpeter are compared for the period 1956 through 2006. Generally, Keynes receives more citations than Schumpeter from 1956 through roughly the mid-1990s. But subsequently until 2006, Schumpeter received more citations than Keynes.

In my study on the research performance of Chinese scientists, I needed to measure their annual publication productivity. After comparing different bibliometric indicators, I didn't adopt simple publication counts or H-index. Here are the two indicators I use: (1). Fractionalized number of SCI papers weighted by citation counts in a three-year window. The number of SCI papers by an author in a given year is counted and adjusted by the number of authors of a paper. Each paper is weighted by its citation counts in the following three years. Actually this indicator is the total citation number an author received because of his/her share of the publications. (2). The highest performance of a scientist. According to the citations received, all papers in a given year are divided into three categories ? high (top 30%), low (bottom 40%) and middle (those in between). A scientist?s highest performance is the category of his/her most cited paper. For example, if one?s single most cited paper belongs to the top 30% category, his/her highest performance is coded as ?High?, no matter how many papers he/she published in a given year. I think the first indicator measures the quantitative aspect of a scientist, while the second measures the qualitative aspect. Here I have some technical questions: 1. Has any recent paper used similar indicators, particularly the second one? 2. For review articles, I only count 1/3 of its citations, since such articles generally get many more citations. Is this weight too low or too high? 3. Please tell me if you know a better practice or how to improve the measurements. Thanks.

In achieving this aim, a review of papers published in five top service research journals is carried out. Design/methodology/approach Papers from the following five service research journals are reviewed: International Journal of Service Industry, Management, Journal of Services Marketing, Journal of Service Research, Managing Service Quality, and Service Industries Journal. The review considers all papers published in the journals over a 14-year period from 1995 to 2008. The abstract and main body of the papers are analyzed for content. Findings This paper identifies the core contribution of researchers from Asian countries. The top five Asian countries identified are Taiwan, Singapore, Hong Kong, Israel, and South Korea. Also identified are patterns and emphases in service research across different countries. Research limitations/implications This paper focuses on five top service research journals over a 14-year period. Patterns of research emphasis in over 280 publications are analyzed. Further studies can include other journals and/or conferences in service science. Practical implications Scholars can benefit from insights into the contribution by Asian researchers in services. Specifically, the paper notes the particular emphases of research from different Asian countries while acknowledging the reach and richness of their contributions. Originality/value The main value of this paper is its uniqueness in discussing the contribution of researchers specific to Asian countries in top service journals. This paper provides valuable insights into the nature of academic publishing of Asian researchers in this burgeoning area.

Material and Methods: A comprehensive list of the most cited critical care medicine articles was generated by searching the Science Citation Index Expanded data set using general critical care terms keywords such as "critical care," critical care journal titles, and keywords for subsubjects of critical care. Results: The final database included 1187 articles published between 1905 and 2006. The most cited article was referenced 4909 times. The most productive search term was intensive care. However, this term only retrieved 25% of the top 100 articles. Furthermore, 662 of the top 1000 articles could not be found using any of the basic critical care search terms. Sepsis, acute lung injury, and mechanical ventilation were the most common areas of focus for the articles retrieved. Conclusion: Retrieving frequently cited, influential articles in critical care requires using multiple search terms and manuscript sources. Periodic compilations of most cited articles may be useful for critical care practitioners and researches to keep abreast of important information. (C) 2010 Published by Elsevier Inc.

The ranking is based on data collected for the year 2007. Journals are ranked using standard citation analysis where we adjust for age, size and self-citation of journals. We also compare the leading economic history journals with the leading journals in economics in order to measure the influence on economics of economic history, and vice versa. With a few exceptions, our results confirm the general idea about what economic history journals are the most influential for economic history, and that, although economic history is quite independent from economics as a whole, knowledge exchange between the two fields is indeed going on.

Many previous works have adopted bibliographic records (i.e., publications) as a source of evidence for representing the areas of expertise [1,2]. In this paper, we present an expertise mapping approach based on a probabilistic keyword annotation model constructed from bibliographic data. To build the model, we use the Science Citation Index (SCI) database as the main publication source due to its large coverage on science and technology (S&T) research areas. To represent the expertise keywords, we use the subject category field of the SCI database which provides general concepts for describing knowledge in UT such as "Biotechnology & Applied Microbiology", "Computer Science, Artificial Intelligence" and "Nanoscience Nanotechnology". The keyword annotation model contains a set of expertise keywords such that each is represented with a probability distribution over a set of terms appearing in titles and abstracts. Given publication records (perhaps from different sources) of an expert, a set of keywords can be automatically assigned to represent his/her area of expertise.

The number of citations (often without counting self-citations or citations from "minor" sources, in whatever way this may be defined), or some measurement based on the number of citations (like the h- or the g-factor) are being used to evaluate scholars; the citation index of a journal (again with a variety of parameters) is seen as measuring the impact of the journal, and hence the importance one assigns to publications there, etc. The number of measurements based on citation numbers is steadily increasing, and their definition has become a science in itself However, they all rest on finding all relevant citations. Thus, "citation mining tools" used for the ISI Web of Knowledge, the Citeseer citation index, Google scholar or software such as the "publishorperish.com" software based on Google scholar, etc., are the critical starting points for all measurement efforts. In this paper we show that the current citation mining techniques do not discover all relevant citations. We propose a technique that increases accuracy substantially and show numeric evaluations for one typical journal. It is clear that in the absence of very reliable citation mining tools all current measurements based on citation counting should be considered with a grain of salt.

To answer this, I estimated PMM's Journal Impact Factor (IF) by examining citations to PMM's 157 publications (volumes 1-9) listed in PsycINFO. The highest IF estimates where based on articles published from 2003-2005 where PMM performed better than average in 2005 (IF = 2.576; z(IF) = 1.07) and 2006 (IF = 2.452; z(IF) = 0.73) compared to sex and gender-related journals. The most cited articles focused on instrument construction and men's body image. I offer suggestions to help bolster PMM's influence as it moves into its second decade: (a) make articles available online ahead of print publication, (b) shorten review turnaround, (c) market PMM publications, and (d) publish special issues with wide appeal.

Using citation and co-citation analysis, this study examined the citation data of journal articles, books, and other publications collected in the Social Sciences Citation Index (SSCI), wherein key research themes in business ethics studies in 1997- 2006 and correlations between these themes were explored. The results show that major research themes in business ethics have shifted in the last decade from research on ethical decision making and on the relationship between corporate social responsibility and corporate performance to research on stakeholder theory in business ethics and on the relationship between consumer behavior and corporate social responsibility. The results of this study help map the invisible network of knowledge production in business ethics research and provide important insights on future business ethics research.

In this report we review the research themes covered in these papers and identify the topics that are active at the moment. The main mechanism for this analysis is a clustering of the research papers based on both cocitation links and text similarity. It is interesting to note that the core set of papers has attracted citations from almost three thousand papers outside the conference collection so it is clear that the CBR conferences are a subpart of a much larger whole. It is remarkable that the research themes revealed by this analysis do not map directly to the subtopics of CBR that might appear in a textbook. Instead they reflect the applications-oriented focus of CBR research, and cover the promising application areas and research challenges that are faced.

We believe that the SIGMETRICS is an active and important community within ASIS&T and we would like to see the interests of this community represented in ASIS&T governance. Becoming an active SIG would allow a greater voice for our members and more opportunities for relevant programming. It may also serve to recruit and retain members with metric-related interests. If you would be willing to sign a petition for the creation of SIGMETRICS as an active SIG, please send an email to cassidysugimoto at gmail.com. KT Vaughan, SIG Cabinet Director, will accept these emails as evidence of support. In addition, if you would be interested in serving as an officer of this SIG, please let us know!

But It=?windows-1252?Q?=92s_?= Not Page Length. Message-ID: The Scholarly Kitchen?s analysis of a smaller data set of Science articles (http://goo.gl/fb/i7v0L) correctly highlights some shortcomings of my preliminary research on the relationship between references and citations covered in Nature News (http://bit.ly/biLx62). There are many unmeasured variables that could potentially explain this association, and I remain skeptical about the possibility of a causal relationship (http://bit.ly/9NEink). Nevertheless, in my data set of over 50,000 Science articles and review articles from 1901 to 2000, the references-citations relationship is unaffected by controlling for page length; the correlation merely changes from .70 to .69 (http://bit.ly/awlxRm). Because I am not an expert in bibliometrics, scientometrics, or infometrics, I welcome any additional constructive criticism on this topic. -- Gregory D.

When we measure the diversity of a paper's references with respect to the structure of its relevant network (we used a co-citation network prior to the publication of the new paper), we found that the extent it alters the structure of the existing network *sometime* ends up as the best predictor of citations in subsequent years. Secondly, the cross-topical references, implemented as connections across co-citation clusters, appear to be also a detectable predictor, but tends to be weaker than the first suspect. The work is still at an early stage. Statistically significant effects are found in some datasets but not in others. I intend to include the relevant functions in the new releases of CiteSpace by the end of the year.

J. Velterop, American Scientist Open Access Forum, 25 August 2010 http://bit.ly/VelteropHunch The results turn out to go strongly contrary to Velterop?s hypothesis. Our ongoing project is comparing citation counts for mandated Green OA articles with those for non-mandated Green OA articles, all published in journals indexed by the Thompson/Reuters ISI database (science and social-science/humanities). (We use only the ISI-indexed sample because the citation counts for our comparisons between OA and non-OA are all derived from ISI.) The four mandated institutions were Southampton University (ECS), Minho, Queensland and CERN. Out of our total set of 11,801 mandated, self-archived OA articles, we first set aside all those (279) articles that had been published in Gold OA journals (i.e., the journals in the DOAJ-indexed subset of ISI-indexed journals) because we were primarily interested in testing the OA citation advantage, which is based on comparing the citation counts of OA articles versus non-OA articles published in the same journal and year. (This can only be done in non-OA journals, because OA journals have no non-OA articles.) This left only the Green OA articles published in non-Gold journals. We then extracted, as control articles for this purely Green OA subset, 10 keyword-matched articles published in the same journal and year. The total number of articles in this control sample for the years 2002-2008 was 41,755 (our preprint for PloS, Gargouri et al. 2010, covers a somewhat smaller, earlier period: 2002-2006, with 20,982 control articles). Next we used a robot to check what percentage of these control articles was OA (freely accessible on the web). Of our total set of 11,801 mandated, self-archived articles, 279 articles (2.4%) had been published in the 63 Gold OA journals (2.6%) among the 2,391 journals in which the authors from our four mandated institutions had published in 2002-2008. Both these estimates of percent Gold OA are about half as big as the total 5% proportion for Gold OA journals among all ISI-indexed journals (active in the past 10 years). To be conservative, we can use the higher figure of 5% as a first estimate of the Gold OA contribution to total OA among all ISI-indexed journals. Now, in our sample, we find that out of the total number of articles published in ISI-indexed journals by authors from our four mandated institutions between 2002-2008 (11,801 articles), about 65.6% of them (7,736 articles) had indeed been made Green OA through self-archiving by their authors, as mandated (7,457 or 63.2% Green only, and 279 or 2.4% both Green and Gold). In contrast, for our 42,395 keyword-matched, non-mandated control articles, the percentage OA was 23.4% (21.9% Green and 1.5% Gold). Bj?rk?s et al?s (2010) corresponding figures for his ISI sample (1282 articles for 2008 alone, calculated in 2009), was 20.6% OA (14% Green, 6.6% Gold). The variance is probably due to discipline blends in the samples, but whichever sample and figures one chooses ? whether our 21.9% Green and 1.5% Gold or Bj?rk?s et al?s 14% Gold and 6.6% Green, the figures fail to bear out Verlterop?s prediction that: ?publishers (the 'gold' road) have actually done more to bring OA about than repositories, even where mandated (the 'green' road).? http://bit.ly/VelteropHunch Moreover (and this is really the most important point of all), the hunch is the wrongest of all precisely for where OA is mandated, for there the percent Green is over 60%, and headed toward 100%. That is the real power of Green OA mandates. Yassine Gargouri Gargouri, Y., Hajjem, C., Lariviere, V., Gingras, Y., Brody, T., Carr, L. and Harnad, S.

It provides a compelling measure of journal status with solid mathematical background, sound axiomatic foundation, intriguing stochastic interpretation, and many interesting relationships to other ranking measures. In this short contribution, we give 10 reasons to motivate the use of the Eigenfactor method. (C) 2010 Elsevier Ltd. All rights reserved.

Internet searches using Web of Science and Scopus were conducted to retrieve citation data for an individual in order to calculate nine variants of Hirsch's h-index. Citations to articles published in a wide range of psychiatric journals in the periods 1995-99 and 2000-05 were analyzed using Web of Science. Comparisons were made between journal impact factor, h-index of citations from publication to 2008, and the proportion of articles cited at least 30 or 50 times. For up to 14 years post-publication, there was a strong positive relationship between journal impact factor and h-index for citations received. Journal impact factor was also compared to the percentage of articles cited at least 30 or 50 times a comparison that showed wide variations between journals with similar impact factors. This study found that 40%-50% of the articles published in the top ten psychiatry journals ranked by impact factor acquire 30 to 50 citations within ten to fifteen years. Despite certain flaws and weaknesses, the h-index provides a better way to assess long-term performance of articles or authors than using a journal's impact factor, and it provides an alternative way to assess a journal's long-term ranking.

Author Full Name(s): Abramo, Giovanni; D'Angelo, Ciriaco Andrea; Di Costa, Flavia Language: English Document Type: Article Author Keywords: Research assessment; Bibliometrics; Citations; Impact factor; University KeyWords Plus: RESEARCH PRODUCTIVITY Abstract: In recent years bibliometricians have paid increasing attention to research evaluation methodological problems, among these being the choice of the most appropriate indicators for evaluating quality of scientific publications, and thus for evaluating the work of single scientists, research groups and entire organizations. Much literature has been devoted to analyzing the robustness of various indicators, and many works warn against the risks of using easily available and relatively simple proxies, such as journal impact factor. The present work continues this line of research, examining whether it is valid that the use of the impact factor should always be avoided in favour of citations, or whether the use of impact factor could be acceptable, even preferable, in certain circumstances. The evaluation was conducted by observing all scientific publications in the hard sciences by Italian universities, for the period 2004-2007. Performance sensitivity analyses were conducted with changing indicators of quality and years of observation.

It combines several indicators grouped into three factors or dimensions, which characterize different aspects of scientific performance. Different profiles or "classes" of scientists are described according to their research performance in each dimension. A series of results based on the findings from the application of this methodology to the study of Spanish National Research Council scientists in Spain in three thematic areas are presented. Special emphasis is made on the identification and description of top scientists from structural and bibliometric perspectives. The effects of age on the productivity and impact of the different classes of scientists are analyzed. The classificatory approach proposed herein may prove a useful tool in support of research assessment at the individual level and for exploring potential determinants of research success.

The technique allocates a different weight to each reference by taking into account the impact of citing journals and citation time intervals. Weighted citation captures prestige, whereas citation counts capture popularity. They compare the value variances for popularity and prestige for articles published in the Journal of the American Society for Information Science and Technology from 1998 to 2007, and find that the majority have comparable status.
