SEP 28 2010. p.NIL_1-NIL_17 BIOMED CENTRAL LTD, LONDON SEARCH TERM(S): JOURNAL item_title KEYWORDS+: RANDOMIZED CONTROLLED-TRIALS; CONSORT STATEMENT; BIOMEDICAL TEXT; ABSTRACTS; ARTICLES ABSTRACT: Background: Clinical trials are one of the most important sources of evidence for guiding evidence-based practice and the design of new trials. However, most of this information is available only in free text e.g., in journal publications - which is labour intensive to process for systematic reviews, meta-analyses, and other evidence synthesis studies. This paper presents an automatic information extraction system, called ExaCT, that assists users with locating and extracting key trial characteristics (e.g., eligibility criteria, sample size, drug dosage, primary outcomes) from full-text journal articles reporting on randomized controlled trials (RCTs). Methods: ExaCT consists of two parts: an information extraction (IE) engine that searches the article for text fragments that best describe the trial characteristics, and a web browser-based user interface that allows human reviewers to assess and modify the suggested selections. The IE engine uses a statistical text classifier to locate those sentences that have the highest probability of describing a trial characteristic. Then, the IE engine's second stage applies simple rules to these sentences to extract text fragments containing the target answer. The same approach is used for all 21 trial characteristics selected for this study. Results: We evaluated ExaCT using 50 previously unseen articles describing RCTs. The text classifier (first stage) was able to recover 88% of relevant sentences among its top five candidates (top5 recall) with the topmost candidate being relevant in 80% of cases (top1 precision). Precision and recall of the extraction rules (second stage) were 93% and 91%, respectively. Together, the two stages of the extraction engine were able to provide (partially) correct solutions in 992 out of 1050 test tasks (94%), with a majority of these (696) representing fully correct and complete answers. Conclusions: Our experiments confirmed the applicability and efficacy of ExaCT. Furthermore, they demonstrated that combining a statistical method with 'weak' extraction rules can identify a variety of study characteristics. The system is flexible and can be extended to handle other characteristics and document types (e.g., study protocols).

Language: English Document Type: Article Author Keywords: graph theory; master equation; h-index; preferential attachment; cumulative advantage KeyWords Plus: ZIPFS LAW; NETWORKS; FLUCTUATIONS; COMPANIES; EVOLUTION Abstract: We develop a model for the distribution of scientific citations. The model involves a dual mechanism: in the direct mechanism, the author of a new paper finds an old paper A and cites it. In the indirect mechanism, the author of a new paper finds an old paper A only via the reference list of a newer intermediary paper B, which has previously cited A. By comparison to citation databases, we find that papers having few citations are cited mainly by the direct mechanism. Papers already having many citations ("classics") are cited mainly by the indirect mechanism. The indirect mechanism gives a power-law tail. The "tipping point" at which a paper becomes a classic is about 25 citations for papers published in the Institute for Scientific Information (ISI) Web of Science database in 1981, 31 for Physical Review D papers published from 1975-1994, and 37 for all publications from a list of high h-index chemists assembled in 2007. The power-law exponent is not universal. Individuals who are highly cited have a systematically smaller exponent than individuals who are less cited.

These, and other existing metrics, are strongly related to scientists' seniority. This article introduces complementary indicators that are unrelated to the number of years since PhD. To illustrate cumulative and career-stage approaches for assessing the scientific impact across a discipline, citations for 611 scientists from 97 U.S. and Canadian social psychology programs are amassed and analyzed. Results provide benchmarks for evaluating impact across the career span in psychology and other disciplines with similar citation patterns. Career-stage indicators provide a very different perspective on individual and program impact than cumulative impact, and may predict emerging scientists and programs. Comparing social groups, Whites and men had higher impact than non-Whites and women, respectively. However, average differences in career stage accounted for most of the difference for both groups.

A lack of presuppositions, a useful research method, and thoughtful experts in these firms helped to uncover some surprising behaviours. The resulting paper attracted citations and may have stimulated research about knowledge as a business resource and a managerial challenge. However, the topic continues to pose questions for further research.

Language: English Document Type: Proceedings Paper Author Keywords: bibliometrics; citation analysis; citation classics; gynecology; landmark articles; obstetrics Abstract: OBJECTIVE: Our objective was to characterize the most frequently cited articles published in obstetrics and gynecology journals during the last 50 years. STUDY DESIGN: We utilized the 2008 edition of Journal Citation Reports and Social Sciences Citation Index database to determine the most frequently cited articles published after 1956. Articles were evaluated for several characteristics, and an unadjusted categorical analysis was performed to compare pre- and post-1980 articles. RESULTS: The 100 most frequently cited articles were published in 11 journals between 1957 and 2004. Most articles were published by US-based authors. Forty-four articles were related to obstetrics and 56 were related to gynecology. The most common study design was observational. There were only 7 randomized controlled trials, and randomized controlled trials were not more common after 1980 (6.3% vs 8.1%; P = .71). CONCLUSION: Most "citation classics" in obstetrics and gynecology are observational studies published in high-impact journals by US-based authors after 1980.

Experts from around the globe will gather in Philadelphia, PA to discuss the new methods that are becoming increasingly important for measuring the usage and value of scholarly and scientific content, including large scientific data sets, and how those measures complement the more traditional, well-known approaches. Registrations for virtual and onsite attendance are still available. The meeting will open with Oliver Pesch, Chief Strategist, EBSCO Information Services, providing a look at what's new with Project COUNTER and SUSHI. He will be followed by Ross MacIntyre, Senior Manager, Mimas, University of Manchester, UK, who will describe a relatively new initiative, PIRUS 2,that takes COUNTER statistics down to the article level. Todd Carpenter, Executive Director, National Information Standards Organization (NISO), will provide an update on Project MESUR, and Dr. Robert D. Chen, Secretary-General, CODATA and Director, CIESIN, Columbia University and Dr. Robert Downs, Senior Digital Archivist, CIESIN, Columbia University, will describe the challenges of accessing, preserving, and citing large datasets. Dr. Jevin West, University of Washington, will open the afternoon session with a discussion of the Eigenfactor, an alternative/complement to the more widely-known journal impact factor. He will be followed Ashlea Higgs, Elsevier, who will talk about a new indicator of journal citation impact, denoted as source normalized impact per paper (SNIP). Dr. Peter Binfield, Public Library of Science, will describe the article level metrics that are currently offered by PLoS, and Jeff Dougherty, Thomson Reuters Healthcare & Science, will talk about the traditional and proven citation approach to measuring usage and value with a look at citation indexes, journal metrics and the impact factor. In closing, both a librarian, Joseph Zucca, Director of Planning and Communication, University of Pennsylvania Libraries, and a publisher, Jonathan Morgan, Assistant Director, Web Strategy and Innovation, American Chemical Society, will discuss the metrics that they use to measure value and usage and how they apply those metrics to key decisions within their organizations.

The impact factor of a journal is the quantitative analysis of the number of citations obtained during a specific period of time. This currently is the standard tool to measure the quality of the publication and a way to evaluate the research trajectory of a scientist. Methods. Search for bibliometric indicators: Journal Citation Reports, SCImago Journal Rank and Potencial Impact Factor for the Spanish Medical Journals of the Instituto de Historia de la Ciencia y Documentacion Lopez Pinero (IHCD). To identify criteria of editorial quality, of visibility and of spreading by reviewing databases such as the Online Regional Information System for Scholarly Journals from Latin America, the Caribbean, Spain and Portugal (LATINDEX), SciELO (Scientific Electronic Library Online), DIALNET and the Collective Periodical Publications Catalogue of Spanish Healthcare Science Libraries, known as C17. Results. For the first time, the Spanish Journal of Chemotherapy appears in the 2009 edition of JCR, previously by joined the two spanish journals Clinical Microbiology and Infectious Diseases and International Microbiology, both ranked at a lower position. While calculating factors of national and international impact of the five publications included in the category of Pharmacology and Pharmacy as part of the project initiated by the IHCD, the Spanish Journal of Chemotherapy showed the best results. Conclusions. The Spanish Journal of Chemotherapy obtained good results in analysed bibliometric indicators, positioning it at the top of the ranking of Spanish medical journals. A good spreading helped to maintain visibility on the publication in the editorial field.

Language: English Document Type: Article Author Keywords: Bibliometrics; Differential item functioning; Citation analysis; Self-citation KeyWords Plus: AUTHOR SELF-CITATIONS; COMMUNICATION Abstract: This paper offers a first approach to the study of citing behaviour in the literature on differential item functioning (DIF) and provides new information about the main characteristics that define that behaviour. With a focus on articles listed in the Web of Science for the period 1975-2000, the present research considers the number of self-citations included in each paper with respect to other bibliometric indicators such as year of publication, the number of signatories to a paper, author's country of origin and the journal in which it was published. In general terms it can be concluded that in studies of DIF the mean percentage of self-citations is around 11%, this figure remaining stable over time; there is a positive correlation between the number of signatories to an article and the number of self-citations.

Author Full Name(s): Frogel, Jay A. Language: English Document Type: Article KeyWords Plus: DIGITAL SKY SURVEY; PROBE WMAP OBSERVATIONS; HUBBLE- SPACE-TELESCOPE; CITATION RATES; IMPACT FACTOR; DATA RELEASE; X- RAY; FACILITIES; PRODUCTIVITY; GALAXIES Abstract: The first decade of the 21st century and the last few years of the 20th have been transformative for ground- and space-based observational astronomy due to new observing facilities, access to digital archives, and growth in use of the Internet for communication and dissemination of information and for access to the archives. How have these three factors affected the characteristics and content of papers published in refereed astronomical journals, as well as the journals themselves? In this and subsequent papers I will propose answers to this question. The analysis in this, the first paper of a series, is based on an examination of the 100 most cited papers in astronomy and astrophysics for each year between 2000 and 2009, inclusive, and supplemental data from 1995 and 1990. The main findings of this analysis are: Over the 10 yr period the total number of authors of the top-100 articles year(-1) has more than tripled. This increase is seen most strongly in papers with more than six authors. The number of unique authors in any given year has more than doubled. The yearly number of papers with five or fewer authors has declined over the same time period. Averaged over the 10 yr period the normalized number of authors per paper increases steadily with citation rank-the most highly cited papers tend to have the largest number of authors and vice versa. This increase is especially notable for papers ranked 1 through 20 in terms of number of citations and number of authors. The distribution of normalized citation counts versus ranking is remarkably constant from year to year and, except for the top-ranked half-dozen or so papers in each year, is very closely approximated by a power law. Nearly all of the papers that show the most divergence from the power-law fit-all in the sense of having a high number of citations-are based on the results of large observational surveys. Among the top-100 papers there is a small but significant correlation of paper length with citation rank. More striking, though, is that the average page length of the top-100 papers is one and a half times that for astronomy papers in general. For every year from 2000 to 2008, the same five journals account for 80 to 85% of the total citations for each year from all of the journals in the category of "Astronomy and Astrophysics" by ISI's Journal Citation Reports. These numbers do not include Nature or Science. Averaged over the 10 yr time period studied in this article, these same five journals account for 77% of the 1000 most cited papers, slightly less than the journals' fractional contribution to the total number of articles published by all journals. The five journals are A&A, AJ, ApJ, ApJS, and MNRAS. Two samples of the top-100 cited papers, both for the 6 yr from 2001 to 2006 but compiled 2.5 yr apart, show that a significant number of articles originally ranked in the top 100 for the year, drop out, and are replaced by other articles as time passes. Most of the dropouts address topics in extragalactic astronomy; their replacements for the most part deal with non-extra-galactic topics. Finally, some additional findings are noted that relate to the entire ensemble of astronomical journals published during the century's first decade. Various indicators of Internet access to astronomical Web sites such as data archives and journal repositories show increases of between factors of 3 and 10 or more. I propose that there are close complementarities between the communication capabilities that Internet usage enables and the strong growth in numbers of authors of th most highly cited papers. Subsequent papers will examine this and other interpretations of the analysis presented here in detail.

Design/methodology/approach - The paper looks at the SIR database which offers essential scientometric information for more than 17,000 scholarly and professional journals based on data licensed from Elsevier's Scopus database and compares this with the JCR database. Findings - The open access SIR database offers very informative new insights to complement those that have been provided by the JCR for more than three decades by the Institute for Scientific Information (ISI) and its successor, the Thomson (later Thomson-Reuters) company. Especially valuable are its features of weighting the citations received based on the prestige of the citing journals, the (partial) exclusion of journal self-citations, and the broader base of source journals. They provide new opportunities to analyse and understand their effects on the ranking of journals. Originality/value - The paper provides useful information on the open access SIR and JCR databases and their effects on the ranking of journals.

In this study, the journals of reproduction biology were compared with JIF and h-indices computed from the ISI Web of Science. This h-index (2001-2008) exhibited a high correlation with the 5 years JIF (2004-2008) (r = 0,64, p = 0.001), the relative h-index showed a weak correlation with the JIF (r = 0.42, p = 0.049). A ranking of 25 reproduction journals is presented on the basis of this JIF or h- index.

Language: English Document Type: Article Author Keywords: Medical publication; Medical journals; Community of medical sciences Iran Abstract: Background: Medical journals are scientific resources where utilization of knowledge is availed and create an environment of competitiveness. To speed up the growth and increase scientific production and in order that the rank of Iranian journals be defined regionally and globally, journal standardization is necessary. This study was done to evaluate the country's medical journals from 2004-2006. Methods: This is a descriptive/analytical study. Evaluation was based on the following; scientific credibility, registry and year of service, journal management, technical quality and accessibility. The number of journals evaluated during 20042006 were 86, 103 and 93, respectively and the process involved 3 phases 1) defining the journal's structural indicators and designing the evaluation form 2) collection, sharing and final confirmation of information with the publication staff 3) data entry, analysis and ranking Results: Improvement and growth of publication depends largely on 5 parameters and its development were based on the following; publication management (61.62 points), scientific credibility (43.80 points), quality of accessing the journals (37.05 points), quality of publication (14.80 points) and registry and year of service (0.02 points). Based on the study, an upward developmental trend of the country's medical journals can be seen and the tools were sufficient in terms of validity and reliability. A revised and more comprehensive checklist that would evaluate all aspects of a publication basing on latest indicators is developed. Conclusion: Evaluations of the country's medical journals not only promote compliance to international standards but also led to more indexing of journals in accredited international indices.

From 1986 to 2007 the scientific literature related to MMP increased sevenfold (397 papers in 1986- 1987 and 2834 in 2006-2007). The number of countries participating in MMP- related research doubled during this period (33 in 1986-1987 to 67 in 2006- 2007), and the USA continually remained the leader. Several industrialized nations (Japan, Germany, UK, Canada, and France) also continuously played important roles, with some emerging Asian countries joining the top 10 most productive countries in 20062007: China (ranked 5th), South Korea (6th), and Taiwan (10th). The MMP-related literature was distributed among a continuously growing number of journals (188 in 1986-1987, 527 in 1996-1997, and 913 in 2006-2007) and The Journal of Biological Chemistry remained the most prolific throughout the entire period. The development of the research involving MMPs during the past two decades was also characterized by a progressive transfer of interest from basic research to clinical medicine; cell biology and pharmacology were important routes of investigation generally pursued by researchers. Journals dedicated to oncology have progressively risen to the top 8 most prolific journals during the 20 year period analyzed.

Author Full Name(s): Cohen, Joanna E.; Chaiton, Michael O.; Planinac, Lynn C. Language: English Document Type: Article KeyWords Plus: ALCOHOL; MODEL; DRUG Abstract: Background: Little is known about the body of tobacco research as a whole. Purpose: This paper examines the changes in literature focus (1980s to 2000s) and identifies areas in need of increased attention. Methods: Tobacco articles randomly selected from searches of the MEDLINE and Web of Science databases were coded according to (1) epidemiologic framework component; (2) study focus; and (3) form of tobacco. Frequencies, cross-tabulations, and tests of proportions were conducted. The analysis was conducted in 2009. Results: From the 1980s to the 2000s, there was a significant decrease in tobacco-related articles focusing on the "agent" and an increase in articles focusing on the "host." Few articles in either decade focused on the "environment" or on the "vector" (<10%). The percentage of study foci addressing health effects decreased, whereas prevalence/use and cessation foci increased. Approximately two thirds of articles focused on the cigarette. Conclusions: The nature of tobacco research has shifted from examining the links between cigarettes and disease to understanding why people smoke and how to help them quit. Proportionately more research could focus on the environment and vector components of the epidemiologic framework, to expand strategies for reducing tobacco-related disease.

Knowledge can then be considered as a meaning which makes a difference. Whereas the communication of information is studied in the information sciences and scientometrics, the communication of meaning has been central to Luhmann's attempts to make the theory of autopoiesis relevant for sociology. Analytical techniques such as semantic maps and the simulation of anticipatory systems enable us to operationalize the distinctions which Luhmann proposed as relevant to the elaboration of Husserl's "horizons of meaning" in empirical research: interactions among communications, the organization of meaning in instantiations, and the self-organization of interhuman communication in terms of symbolically generalized media such as truth, love, and power. Horizons of meaning, however, remain uncertain orders of expectations, and one should caution against reification from the meta-biological perspective of systems theory.

Message-ID: How Do Emerging Technologies Conquer the World? An Exploration of Patterns of Diffusion and Network Formation Grasping the fruits of "emerging technologies" is an objective of many government priority programs in a knowledge-based and globalizing economy. We use the publication records (in the Science Citation Index) of two emerging technologies to study the mechanisms of diffusion in the case of two innovation trajectories: small interference RNA (siRNA) and nano-crystalline solar cells (NCSC). Methods for analyzing and visualizing geographical and cognitive diffusion are specified as indicators of different dynamics. Geographical diffusion is illustrated with overlays to Google Maps; cognitive diffusion is mapped using an overlay to a map based on the ISI Subject Categories. The evolving geographical networks show both preferential attachment and small-world characteristics. The strength of preferential attachment decreases over time, while the network evolves into an oligopolistic control structure with small-world characteristics. The transferability of the research technology in cognitive terms--that is, the transition from "mode-1" to "mode-2" research--is suggested as the crucial difference in explaining the different rates of diffusion between siRNA and NCSC. http://arxiv.org/abs/1011.3120 Authors: Loet Leydesdorff , Ismael Rafols ** apologies for cross-postings _____ Loet Leydesdorff Professor, University of Amsterdam Amsterdam School of Communications Research (ASCoR) Kloveniersburgwal 48, 1012 CX Amsterdam.

As you may know, it is not currently possible to track citations to datasets through Scopus and ISI Web of Science. The purpose of this hub is to provide: - a central meeting ground for the many individuals and organizations interested in this issue - a living document that captures current unmet needs - an area to inventory and develop initiatives to encourage vendors to address these issues as soon as possible ASIS&T SIG/STI and SIG/METRICS members are uniquely positioned to provide insight and direction, with expertise in preservation, scientific data and bibliometrics. Individual and collective feedback would be most valuable. Please check it out, add what you know, and send the link around to others you know who care about this issue so that we can achieve data citation tracking through Scopus and Web of Science ASAP.

Language: English Document Type: Article Author Keywords: Scientometrics; Bibliometrics; Citation studies; Publication productivity; h-index; Organic chemistry; Role model scientists Abstract: This paper highlights quantitatively the growth and development of chemical science research by J.S. Yadav during the period from 1986-2009. During this period he has published 722 papers (702 research articles) in various domains. The data used was from Thomson/ISI Web of Science. This study attempts to evaluate the publications of J. S. Yadav in relation to his contribution to the knowledge domain of chemical science and his role for the advancement of chemical science in India and elsewhere in a span of about two and half decades. His papers have been scattered in 56 high impact factor scientific journals. The percentage of collaborative work (99.7) was very high. His highest degree of collaboration 0.1925, was found during 2002-2003. The h index of 41 after 24 years of scientific activity is a clear indication of his consistent publication productivity behaviour. Addresses: [Varaprasad, S. J.

Since the average age of university faculties is increasing not only in the United States but also in Europe, the question arises as to whether this belief is correct. If it were valid, the abolition of compulsory retirement in the United States and some parts of Canada would lower the productivity of these university systems. To address this question, this article reviews research on the association of age and scientific productivity conducted during the last four decades in North America and Europe. Whereas early research typically showed a decline in productivity after the ages of 40 to 45 years, this decline has been absent in more recent studies. Explanations for this change are discussed.

P.; Chander, Romesh; Madras, Giridhar Language: English Document Type: Article Author Keywords: Indian and international institutions; publications; research performance; scientometric analysis Abstract: We have carried out a three-part study comparing the research performance of Indian institutions with that of other international institutions. In the first part, the publication profiles of various Indian institutions were examined and ranked based on the h-index and p-index. We found that the institutions of national importance contributed the highest in terms of publications and citations per institution. In the second part of the study, we looked at the publication profiles of various Indian institutions in the high- impact journals and compared these profiles against that of the top Asian and US universities. We found that the number of papers in these journals from India was miniscule compared to the US universities. Recognizing that the publication profiles of various institutions depend on the field/departments, we studied the publication profiles of many science and engineering departments at the Indian Institute of Science (IISc), Bangalore, the Indian Institutes of Technology, as well as top Indian universities. Because the number of faculty in each department varies widely, we have computed the publications and citations per faculty per year for each department. We have also compared this with other departments in various Asian and US universities. We found that the top Indian institution based on various parameters in various disciplines was IISc, but overall even the top Indian institutions do not compare favourably with the top US or Asian universities.

Author Full Name(s): Arbesman, Samuel; Laughlin, Gregory Language: English Document Type: Article Abstract: Background: The search for a habitable extrasolar planet has long interested scientists, but only recently have the tools become available to search for such planets. In the past decades, the number of known extrasolar planets has ballooned into the hundreds, and with it, the expectation that the discovery of the first Earth-like extrasolar planet is not far off. Methodology/Principal Findings: Here, we develop a novel metric of habitability for discovered planets and use this to arrive at a prediction for when the first habitable planet will be discovered. Using a bootstrap analysis of currently discovered exoplanets, we predict the discovery of the first Earth-like planet to be announced in the first half of 2011, with the likeliest date being early May 2011. Conclusions/Significance: Our predictions, using only the properties of previously discovered exoplanets, accord well with external estimates for the discovery of the first potentially habitable extrasolar planet and highlight the the usefulness of predictive scientometric techniques to understand the pace of scientific discovery in many fields.

Our paper has two major goals. First, we discuss the limits of numerical assessment tools as applied to computer science publications. Second, we give guidelines on how to write a good paper, where to submit the manuscript, and how to deal with the reviewing process. We report our experience as editors of International Journal of Computers Communications & Control (IJCCC). We analyze two important aspects of publishing: plagiarism and peer reviewing. As an example, we discuss the promotion assessment criteria used in the Romanian academic system. We express openly our concerns about how our work is evaluated, especially by the existent bibliometric products. Our conclusion is that we should combine bibliometric measures with human interpretation.

Author Full Name(s): Fernandez-Llimos, Fernando; Mendes, Ana Maria Language: Portuguese Document Type: Article Abstract: Local and national scientific journals have been widely criticized by some authors. Additionally, they are quite rarely indexed at international databases, which results in a reduced visibility of their articles. Objective: To analyze international scientific productions of authors publishing in Acta Medica Portuguesa during 2008. Methods: A database with all the authors publishing in Acta Medica Portuguesa in 2008 was built. In July 2009, production of all those authors from the previous five years (20032007) was retrieved from Science Citation Index. Journals where they published, Impact Factors of those journals, articles' references, and times cited were analyzed. Results: The 78 articles published by Acta Medica Portuguesa in 2008 were produced by 259 different authors. Ninety four (36.3%) of those authors wrote 420 articles from 2003 to 2007 indexed at Science Citation Index. These articles were published in 249 different journals, with an average Impact Factor of 2.973 (SD = 2.92). Journal with highest Impact Factor was The Lancet (IF2008 = 28.409) with two papers published. Eighty seven of those authors received some citation to their articles, with a total amount of 5001 cites. Out of the 14035 references on those 420 articles, only 10 cited any article published in Acta Medica Portuguesa. Conclusion: Authors publishing in Acta Medica Portuguesa produce a good amount of international publications in journals with an acceptable Impact Factor and they receive quite a good number of citations. Conversely, these authors when publishing in international journals have an extremely low citation of articles published in Acta Medica Portuguesa.

Language: English Document Type: Article Author Keywords: Stem cells; Plasticity; Development; Public policy Abstract: As scientists position themselves in translating the therapeutic potential of stem cells from laboratory to clinical applications, publishing companies have taken this rapidly evolving field as a unique opportunity to launch new journals for dissemination of stem cell research. Over the last decade, the significant increase in the number of stem cell-based journals has created a conundrum. At stake is the pressure for these new journals to build their reputation by maintaining publication standards, while at the same time attracting a cadre of stem cell researchers to consider their journals as the publication of choice. We discuss here a prophetic path of survival for these journals which likely will closely mimic the core scientific and translational value of stem cells, namely their capacity to proliferate and differentiate into something meaningful!.

Bibliometric techniques could help us find research hotspots and grasp the research direction yet can't reveal huge hidden information in massive literature since the existing bibliometric analysis techniques employ mainly simple statistical analysis techniques. Hence, we propose to introduce data mining analysis techniques into bibliometrics analysis, and expect to reach some instructive conclusions by mining relations among information like keywords, authors, research institutions, publications and so on. We take the subject 'data mining' as our research object and analyze the records by the method of association rule analysis. Finally, we get some valuable conclusions that verify the idea's feasibility. The results of this research would not only provide a reference for data mining research but also be applied to other research fields.

Language: English Document Type: Article KeyWords Plus: JOURNALS Abstract: Objectives: The study updates Schloman's 1997 study, "Mapping the Literature of Health Education.'' The authors identify an updated list of core health education journals and determine the coverage of these journals by electronic indexes. Methods: Citations from four source journals for the years 2006 to 2008 were analyzed using the established methodology of the "Mapping the Literature of Allied Health Project.'' The cited journals were divided into three zones of productivity by using Bradford's Law of Scattering. Results: There were 19,907 citations in 602 source articles. Journal articles were the most commonly cited format type. Of the 1,896 journal titles cited, 20 (1.1%) made up the core journals. Together, the fields of medicine, health education, and psychology accounted for 85.0% of the journals in the core. Self-citation was found to be a common practice in the source journals. Scopus had the broadest journal coverage of the indexes examined. Conclusions: The results of this study provide a new picture of the health education literature: The volume has grown significantly, cites older materials, and relies less on sexual health journals and more on psychology journals.

These changes have been a boon to researchers, who presumably no longer have to travel across campus or even down the hall to the library for articles. Instead, they retrieve articles with just a few clicks on their home or office computers. Libraries are reducing their print collections due to decreased utilization and increased access to online journals [1?3]. The convenience of accessing the online collection remotely instead of having to walk into the library has been cited as a reason [4]. A previous study that examined the impact of online journals on the citation patterns of medical school faculty found that when medical faculty had access to a small print collection and a large online journal collection, the use of the print collection significantly decreased. However, when faculty had access to a large print collection in addition to a large online collection, the impact on the use of the existing print collection was minimal [5]. A 2006 study that surveyed health sciences librarians also found that researchers are still using print journals in this electronic age [6]. The purpose of this study is to determine how online journal collections are impacting the citation patterns of researchers in dentistry, nursing, and pharmacy. Journal citation patterns before and after the introduction of online journals will be examined to determine whether researchers are more likely to limit the journal articles they cite to those journals available online rather than those available only in print.

Author Full Name(s): Marx, Werner; Bornmann, Lutz; Cardona, Manuel Language: English Document Type: Article KeyWords Plus: H-INDEX; DISTRIBUTIONS; UNIVERSALITY; RELATIVITY; SCIENCE Abstract: In this study, reference standards and reference multipliers are suggested as a means to compare the citation impact of earlier research publications in physics (from the period of "Little Science" in the early 20th century) with that of contemporary papers (from the period of "Big Science," beginning around 1960). For the development of time-specific reference standards, the authors determined (a) the mean citation rates of papers in selected physics journals as well as (b) the mean citation rates of all papers in physics published in 1900 (Little Science) and in 2000 (Big Science); this was accomplished by relying on the processes of field-specific standardization in bibliometry. For the sake of developing reference multipliers with which the citation impact of earlier papers can be adjusted to the citation impact of contemporary papers, they combined the reference standards calculated for 1900 and 2000 into their ratio. The use of reference multipliers is demonstrated by means of two examples involving the time adjusted h index values for Max Planck and Albert Einstein.

Language: English Document Type: Article KeyWords Plus: JOURNAL IMPACT FACTORS; OF-SCIENCE; SOCIAL-SCIENCES; RESEARCH OUTPUT; HIRSCH-INDEX; SCOPUS; PERFORMANCE; REFERENCES; INDICATORS; AUTHORS Abstract: Hirsch's h index is becoming the standard measure of an individual's research accomplishments. The aggregation of individuals' measures is also the basis for global measures at institutional or national levels. To investigate whether the h index can be reliably computed through alternative sources of citation records, the Web of Science (WoS), PsycINFO and Google Scholar (GS) were used to collect citation records for known publications of four Spanish psychologists. Compared with WoS, PsycINFO included a larger percentage of publication records, whereas GS outperformed WoS and PsycINFO in this respect. Compared with WoS, PsycINFO retrieved a larger number of citations in unique areas of psychology, but it retrieved a smaller number of citations in areas that are close to statistics or the neurosciences, whereas GS retrieved the largest numbers of citations in all cases. Incorrect citations were scarce in Wos (0.3%), more prevalent in PsycINFO (1.1%), and overwhelming in GS (16.5%). All platforms retrieved unique citations, the largest set coming from GS. WoS and PsycINFO cover distinct areas of psychology unevenly, thus applying different penalties on the h index of researches working in different fields. Obtaining fair and accurate h indices required the union of citations retrieved by all three platforms.

Citer-based outcome measures were also compared with more traditional citation-based measures for levels of association. The authors found that there are significant differences in citer- based outcomes among the three broad subject areas examined and that there is a high degree of correlation between citer and citation-based measures for all measures compared, except for two outcomes calculated for the social sciences. Citer-based measures do produce slightly different rankings of authors based on citer counts when compared to more traditional citation counts. Examples are provided. Citation measures may not adequately address the influence, or reach, of an author because citations usually do not address the origin of the citation beyond self-citations.

Language: English Document Type: Article Author Keywords: Referencing; Information management; Software tools KeyWords Plus: INTELLECTUAL STRUCTURE; SCIENTIFIC LITERATURE; GRAPH VISUALIZATION; AUTHOR COCITATION; SCIENCE Abstract: Purpose - The paper's aim is to document the development of a novel tool to address the inadequacies of existing cocitation visualization tools. Design/methodology/approach - The paper demonstrates the visualized effects of this tool and supplements the results with a case study that utilizes a large data set to explore the cross-field studies among different computer science fields. Findings - The tool displays cocitation graphs with latent visual cues and allows direct manipulation of the visualized graphs. The tool also facilitates the exploration of the relationships between articles in the graphs. Research limitations/implications - The indirect cocitation relationships are vividly visualized by the citation network itself. The context lost by the conventional cocitation network may be preserved. Instead of being linked by explicit lines, the implicit cocitation relationships are shown by the closeness among the cocited nodes. Practical implications - The preserved context of a cocitation network may facilitate the exploration of latent cross-field studies. The cocitation visualization tool demonstrates that the context of the cocitation graph is preserved by using the citation network itself to reveal cocitation relationships. Originality/value - The cocitation relationships are implied by the closeness among cocited nodes in a citation graph. The paper documents this novel approach which has not been seen before.

Three handbooks on research in science education, language education, and educational technology were used to identify a sample of 112 accomplished scholars. Google Scholar, Web of Science, and Scopus citations for 401 journal articles published by these authors during the 5-year period from 2003 to 2007 were then analyzed. The findings illustrate the promise and pitfalls of using Google Scholar for characterizing the influence of research output, particularly in terms of differences between the three subfields in publication practices. A calibration of the growth of Google Scholar citations is also provided.

Journal rankings can be used to guide the selection. but their usefulness may be limited for particular audiences. In this paper, It is argued that especially young researchers and researchers in interdisciplinary fields can benefit from targeting research efforts to a specific community. This can be facilitated by an individually built journal ranking that exploits a community building perspective and by a more transparent process of use The approach introduced here is based on an analysis of both traditional journal rankings and behavior of academic communities As a result, we present a procedure for building and using an individual journal ranking, Its tentative composition and the ranking calculation In addition, we suggest measures for evaluating the ranking use. The results presented in this paper are focused on but not limited to young researchers and emerging disciplines.

Author Full Name(s): Larson, Jeffrey D.; Sisolak, Barbara Benisch; King, Timothy W. Language: English Document Type: Article KeyWords Plus: MISREPRESENTATION; PUBLICATIONS; AUTHORSHIP Abstract: Background: In today's morally flexible society, breaches in professionalism abound. Professionalism and integrity are core values required of all physicians. Falsification of application information has been demonstrated in some applicant populations. As one of the most competitive fields among residency training programs, applications to an integrated plastic surgery residency program were analyzed to determine whether nonverifiable or "ghost" publications were being included by applicants. Methods: The study population included 232 applicants to the University of Wisconsin integrated plastic surgery program in 2008 to 2009. In each application, citation information for journal articles, book chapters, and other publications were reviewed for accuracy. The protocol included verifying citation accuracy in the PubMed/MEDLINE database. Citations that could not be verified were submitted to the department of surgery librarian for further review. Other applicant data were also collected to identify potential predictive factors for including ghost publications. Results: Two hundred thirty-two applications listed 876 citations that were reviewed. Two hundred sixty (30 percent) were identified as citations for which publication was pending and were excluded from analysis. A primary search successfully verified 415 citations (47 percent). A secondary search successfully verified 148 citations (17 percent) as well as identified citations that were complicated, incorrectly cited, or ghost publications. There were 14 ghost publications (2 percent). Conclusions: The inclusion of nonverifiable citations among plastic surgery applicants is low. Nonetheless, we should insist on professionalism and integrity as core values in medical students pursuing plastic surgery, as any "ghost" publication raises an index of suspicion for potentially fraudulent activity.

L.; Haynes, R. B. Language: English Document Type: Article Author Keywords: health informatics; clinical trials KeyWords Plus: OPTIMAL SEARCH STRATEGIES; MEDICINE; MEDLINE Abstract: Objective: This study identified the journals with the highest yield of clinical obesity research articles and surveyed the scatter of such studies across journals. The study exemplifies an approach to establish a journal collection that is likely to contain most new knowledge about a field. Design and methods: All original studies that were cited in 40 systematic reviews about obesity topics ('included studies') were compiled and journal titles in which they were published were extracted. The journals were ranked by the number of included studies. The highest-yielding journals for clinical obesity and the scatter across journal titles were determined. A subset of these journals was created in MEDLINE (PubMed) to test search recall and precision for high-quality studies of obesity treatment (that is, articles that pass predetermined methodology criteria, including random allocation of participants to comparison groups, assessment of clinical outcomes, and at least 80% follow-up). Results: Articles in 252 journals were cited in the systematic reviews. The three highest-yielding journals specialized in obesity, but they published only 19.2% of the research, leaving 80.8% scattered across 249 non-obesity journals. The MEDLINE journal subset comprised 241 journals (11 journals were not indexed in MEDLINE) and included 82% of the clinical obesity research articles retrieved by a search for high-quality treatment studies ('recall' of 82%). Of the articles retrieved, 11% were about clinical obesity care ('precision' of 11%), compared with precision of 6% for obesity treatment studies in the full MEDLINE database. Conclusion: Obesity journals captured only a small proportion of the literature on clinical obesity care. Those wishing to keep up in this field will need to develop more inclusive strategies than reading these specialty journals. A journal subset based on these findings may be useful when searching large electronic databases to increase search precision.

It is awarded to an individual in recognition of excellence through outstanding, sustained career achievements in the field of quantitative studies of science and their applications. Established originally in 1984 by Tibor Braun and the publishers of journal of Scientometrics to honor the memory of Derek John de Solla Price, one of the founders of scientometrics, the Price Award has been awarded 15 times during 1984-2010. It is sponsored by the Publisher of the journal. The Award has no monetary value. The Derek Price Medal Award (DPMA) comprises an engraved bronze medal and certificate. The previous awardees of the DPMA are: 1984 E. Garfield 1985 H.J. Moravcsik 1986 T. Braun 1987 H. Small, V. V. Nalimov 1988 F. Narin 1989 J. Vlachy, B.C. Brookes 1993 A. Schubert 1995 R. K.

McCain 2009 P. Vinkler, M. Zitt The Derek Price Medal Award 2011 (DPMA-11) will be presented at one of the 2011 conferences of the field. Nominations of worthy candidates for DPMA-11 are widely solicited from the international community of practicing scientometricians and may be initiated by individual colleagues or their institutes including the members of the Editorial Advisory Board of the journal. There are no restrictions with respect to age, gender, nationality or other to who may be nominated among those whose achievements fall within the guidelines of the Derek Price Medal Award. A copy of the complete guideline can be obtained from: Professor Tibor Braun, the Editor-in-Chief of the Scientometrics (Email: braun at mail.iif.hu). It is the responsibility of the nominator to prepare a complete, comprehensive and convincing statement of the outstanding achievements and contributions to the field that deserve of recognition through this award. There are no special forms for nomination. Each nomination, to be considered complete, must comprise: a signed nomination letter and a concise but comprehensive 500-1000 word citation stressing the candidate's outstanding and sustained contributions to scientometrics. The nominator must ensure that all of these materials are included in the above sequence in a single file prior to sending it. It is preferable to use Adobe Acrobat (.pdf) format but MS Word (.doc[x]) and Rich Text Format (.rtf) might be used as well. Additional material will not be considered by 2011 Derek Price Medal Selection Panel (DPSP-11). The nominations will be considered on their scientific merit, based entirely on the strength of the documentation provided, by DPSP-11 which will not otherwise research the background of the nominee. Only one nomination per candidate will be accepted by DPSP-11. The decision of DPSP-11 will be considered final by all parties and may not be appealed or reconsidered, such as on the basis of supplemental documentation. In order to harmonize the presentation of the complete CV of the candidates, you are requested to follow the following format. 1. The candidate The head of the nomination is formed by the complete name (incl. titles), affiliation and address (incl. email) of the candidate. 2. Motivation The first part of this section is a concise but sound and meaningful motivation, in which the nominator should explain why he/she considers the candidate worth to be awarded the DPMA. The recommendation should briefly summarise the candidate's major merits focussing on relevant achievements in research, education, organisation and communication from a non-profit perspective. Commercial aspects are not relevant for awarding the Price Medal. This statement has ideally 300-500 words; it should be followed by a more detailed presentation of the candidate's contributions to the fields of quantitative studies of science organised as follows. 2.1. Research activity The candidate's main achievements in academic research should be described. It should be convincingly explained how the candidate has shaped research topics in our field. The description - organised by topics - should be accompanied by short lists of the most important publications in the concerned subjects. 2.2. Education Evidence should be given of the candidate's role in the training and education of a new generation of experts in our field. This includes, among others, teaching activities at universities, summer schools as well as supervision of master and PhD students and the publication of text books in the field of quantitative science studies. 2.3. Organisation and communication This issue comprises all activities concentrated on the institutionalisation of our field such as organisation of conferences, the edition of proceedings and special issues in journals, launching scientific journals and research programmes. Functions in editorial boards and academic organisations also belong to this section. Nominators should also report if there is evidence of strong communication and interaction with scientists in other communities promoting our field and report the candidate's social impact and visibility in the public. You could include any other item which is worth noting but not mentioned above specifically.

Phil's original 2008 sample of 247 OA and 1372 non-OA articles in 11 journals one year after publication has now been extended to 712 OA and 2533 non-OA articles in 36 journals 2-3 years after publication. The result is a significant download advantage for OA articles but no significant citation advantage. (Brody et al (2006) reported -- for physics article in Arxiv -- that a download advantage in the first 6 months after publication is correlated with a citation advantage 1.5 years or more after that; see also Gentil-Beccot et al's (2009) data, below).

Gentil-Beccot, A, Mele, S & Brooks TC (2009) Citing and reading behaviours in high-energy physics. Scientometrics 10.1007/s11192-009-0111-1 The only way to describe this outcome is as a non-replication of the OA Citation Advantage on this particular sample; it is most definitely not a demonstration that the OA Advantage is an artifact of self-selection, since there is no control group demonstrating the presence of the citation advantage with self-selected OA and the absence of the citation advantage with randomized OA across the same sample and time-span: There is simply the failure to detect any citation advantage at all. This failure to replicate is almost certainly due to the small sample size as well as the short time-span. (Phil's a-priori estimates of the sample size required to detect a 20% difference took no account of the fact that citations grow with time; and the a-priori criterion fails even to be met for the self-selected subsample of 65.) "I could not detect the effect in a much smaller and briefer sample than others" is hardly news! Compare the sample size of Phil's negative results with the sample-sizes and time-spans of some of the studies that found positive results: And here is how the OA citation advantage builds up with time (read the curves on the left from bottom to top to see the effect of a longer and longer time interval: [the topmost curve should read "1998-2008" rather than "1998-2001"]): Gargouri, Y., Hajjem, C., Lariviere, V., Gingras, Y., Brody, T., Carr, L. and Harnad, S.

Such a system can be an observer, but also a discourse, for example, operationalized as a set of documents. The measurement of semantics as similarity in patterns (correlations) and latent variables (factor analysis) has been enhanced by computer techniques and the use of statistics; for example, in "Latent Semantic Analysis". This communication provides an introduction, an example, pointers to relevant software, and summarizes the choices that can be made by the analyst.

Phil, I've always been interested in sample sizes. That's why all of our studies have been based on samples that have been orders of magnitude bigger than (for example) yours (see again Table 1, below)! But let's not confuse effect-size and the sample-size needed to detect a statistically significant effect; that's not a question about effect size but about variability: With high variability you may need a large sample to reach statistical significance, but it does not necessarily follow that the size of the effect itself will be small! The size of the OA citation advantage does indeed vary considerably (from field to field, year to year, and sample to sample) (see Figure 1 and Figure 2, below). The biggest effect observed has been in physics, where there is the added advantage of providing OA to the unrefereed preprint as much as a year or more prior to publication (but this is risky, and not advisable in all fields). But our fundamental point has been that the OA citation advantage is positive, significant, and present in every field tested so far -- bigger in some fields than others, but (just about) always positive, significant, and there. (There have been a few other non-replications, usually on small samples: Your non-replication is not the first. Bigger samples and longer intervals make it more likely that you will detect the effect. See Figure 3, below.) Whenever I've written of the size of the OA citation advantage, I've referred to the entire observed range of the effect, not just to its maximum observed value, nor even just its mean, median or mode. But whenever I've translated the OA citation advantage into its potential economic benefit (e.g., how much mandating OA can enhance the percentage of citation impact per dollar spent on research), I've always used, conservatively, only the lowest end of that range. Moreover, our latest study (Gargouri et al 2010) confirmed the Pareto/Seglen effect, which is that not only are citations not equally distributed across all articles (the distribution is highly skewed, with the top 20% of articles receiving 80% of the citations), but the OA citation advantage is likewise correspondingly skewed (see Figure 4, below), with the most citeable articles benefitting the most from OA (a user self-selection effect, not an author self-selection effect). This variability also underlies the variation in the size of the OA citation advantage. So, yes, unciteable articles will not benefit from OA at all. And the most citeable articles will benefit most. But (with a sufficiently large sample and a long enough interval), there is (just about) always a significant, positive OA citation advantage -- in some fields and for some articles a very large one, but for all fields a significant, positive one. Overall, across all fields of scientific and scholarly research produced by universities and funded by funders, that adds up to a sizeable benefit to research, researchers, their institutions, their funders, and the public that funds the funders and for whose benefit the research is being done, and funded -- a benefit that is worth having, by mandating OA, rather than continuing to lose, needlessly, as now. That implication is very clear -- and it certainly is not the implication you cite in your December summary in the APS house journal, The Physiologist: PD: "The fact that we observe an increase in readership and visitors for Open Access articles but no citation advantage suggests that scientific authors are adequately served by the current APS model of information dissemination." What your findings show is that there was no OA citation advantage in your (small) sample. Point taken. But the interpretation is a mighty stretch, if not an exercise in APS spin. There is something far, far bigger and more important at stake here than the revenue streams and modus operandi of APS -- or any other journal publisher. It's time for the publisher tail to stop trying to wag the research dog...

In my view, Stevan Harnad's criticism of Phil misses the point. Stevan states that "with high variability you may need a large sample to reach statistical significance, but it does not necessarily follow that the size of the effect itself will be small". This is true. However, in the case of Phil's results, it is not difficult to see that the true effect size is unlikely to be of a magnitude that has much practical significance. Phil kindly provided me with the data of his study. Using his data, the effect size can be estimated in a straightforward way. I define the effect size as the average number of citations of OA articles minus the average number of citations of non-OA articles (using a three year time interval). I obtained a point estimate of -0.10, which also follows directly from Phil's paper. The associated 95% confidence interval is (-1.88, 1.67). (I calculated the confidence interval in two different ways, namely under the assumption that the effect size estimator follows a normal distribution and using a bootstrapping approach that does not make any distributional assumptions. Both approaches yielded the same confidence interval.) These calculations provide essentially the same information as Phil's paper, but in a slightly different way. It follows from the confidence interval that the true effect size is unlikely to be greater than 1.67, which means that a reasonable upper bound for the OA citation advantage in the journals studied by Phil is about 16% (1.67 divided by 10.7, i.e., 1.67 divided by the average number of citations of all articles in Phil's study). Hence, even though Phil's sample is much smaller than in some other studies, he is able to show that in the journals he studied an OA citation advantage is either absent or of a rather small size (especially when compared with the results reported in some other studies). Stevan also states that "(with a sufficiently large sample and a long enough interval), there is (just about) always a significant, positive OA citation advantage -- in some fields and for some articles a very large one, but for all fields a significant, positive one." This might well be true, but it is not relevant. With a larger sample, Phil might have obtained a statistically significant, positive OA citation advantage, but the effect size would still be small. Small effects, although statistically significant, have little or no practical significance. In my view, Phil has convincingly shown that, at least for the journals and the time intervals he studied, there is no meaningful OA citation advantage.

I met him first at a meeting in Bielefeld shortly after the tumbling of the Berlin wall, organized by Peter Weingart at the ITZ as a meeting with Eastern-European colleagues (who we did not know in person until then). I remember that I arrived late in the evening after a long day with education and everything was dark. Then, I saw someone behind a window who reacted to my waiving and he invited me for tea and goat cheese. These were the only things he was eating. Later I understood that Jan always brings his own food. He usually traveled by car with a lot of food in the trunk. Jan's strength was that he had marvelous control over the data. He gave the impression that he had filed all the paper copies in one of these castles in Bohemia. We met over the years irregularly; he told me the last time - at the meeting in September in Leiden - that he had sometimes given up on the field because of the weight that the bureaucrats in Brussels sometimes lay on their methods of evaluation. "They have invested so much in error, that they cannot back off." They once hired him Brussels for three months, but I don't believe that this was the happiest period in his life.

If you mean the 3 -year population of articles in the 36 (mostly APS) journals that Phil actually tested, I agree. But if you mean that general population of articles, in multiple different fields, tested by multiple independent investigators, reporting a significant (and sometimes quite sizeable) OA citation advantage (with the exception of a very small number of negative or null outcomes), then Phil's study certainly has *not* shown "that an OA citation advantage of reasonable size is unlikely to exist" in *that* underlying population. It would take a null meta-analysis, not just one null outcome, to be able to show that. (Otherwise any repeatedly observed effect could be dismissed on the basis of one non-replication!) What Phil set out to show was that *the repeatedly observed OA citation advantage was an artifact of author self-selection*, and the way he hoped to show that -- and it's a good way -- was to show that randomly imposed OA eliminates the OA citation advantage. So far so good. But what Phil failed to do was to replicate the OA citation advantage in the case of author self-selection, and then show that it is eliminated by randomization -- in the same journal population and time interval. Instead he just found no OA citation advantage at all, for that journal population and interval. That, to repeat, is one non-replication, for that journal population and time interval. It is not a demonstration that the repeatedly observed OA citation advantage is an artifact of author self-selection. And -- not to focus only on negative results -- let me suggest that it is pertinent to this question that we too did a test of the self-selection hypothesis -- on a much larger sample across more fields and a longer time interval -- and we not only found "an OA citation advantage of reasonable size" for self-selected OA, but we found that the advantage was the same size for mandated OA. We accordingly conclude that "an OA citation advantage of reasonable size is likely to exist in the underlying population" if you test for it, and your sample is big enough and long enough -- except perhaps in Phil's sample of (mostly APS) journals...

Let's move to your new concern about generalizability: While I can't claim negative results across all fields and across all times, our randomized controlled trials (RCTs) did involve 36 journals produced by 7 different publishers in the medical, biological, and multi-disciplinary sciences, plus the social sciences and humanities. The nature of the RCTs means a lot of human intervention goes in to set up and run the experiments. In comparison, retrospective observational studies (the studies you cite as comparisons) are largely automated and are able to gather a huge amount of data quickly with little human intervention. Yet, if you are basing your comparison solely on number of journals and number of articles, then you are completely missing the rationale for conducting the RCTs in the first place: By design, RCTs are better at isolating possible causes, determining the direction of causation, and ruling out confounding variables. While it is impossible to prove cause and effect, RCTs generally provide much stronger evidence than retrospective observational studies. Your last concern was about a self-selection control group: There were not a lot of cases of self-archiving in our dataset. Remember that we were not studying physics and that our studies began in 2007. You will note that I report a positive citation effect in my Appendix, but because the act of self-archiving was out of our control, we could not distinguish between access and self-selection as a definitive cause. I also report in my dissertation that articles selected and promoted by editors were more highly-cited, but it appears that editors were simply selecting more citable articles (e.g. reviews) to promote. --Phil -- Philip M.

Jan was also of great help for follow up publications insisting than we should use a lot of diagrams and not only equations, and really taught me how to do them, so that scientometricians could understand. He always was a researchers with a visual talent, who could express very clearly basic trends, laws, structures in graphs and diagrams. But what most impressed me when I first had the ability to meet him in Prague and discuss things with him at home were long lists of very accurately written down long lists of numbers on paper (!) (I talk about 1985). I always thought that there is no scientometric data, no possibility to count items/attributes related to scientific publications Jan Vlachy would not have already explored by himself. Working for the journal he published a lot a smaller studies encompassing very interesting, and still actual, problems of scientometrics. I just looked up the springer website, and it seems that they have inbetween archived the whole journal and a lot of his material in there is available. http://www.springerlink.com/content/0011-4626/?k=Vlachy But, I also still think is would be valuable to have an archive of his papers (not only the once in The Czech J Phys) on-line for the community. The last time I saw him after many years and with great pleasure again was at the Leiden conference, and we spoke about that he should make his publications on-line available. He agreed but I don't recall if he had only a plan to do this or if this plan was a bit more mature. As Loet, I also heard him talking about re-opening a series of workshops in Prague on bibliometrics again, and having a first meeting in 2011. It is a great loss ....

Phil, I'm not sure why you speak of "concession" since we are talking here about data, not our respective opinions or preferences. Your one-year sample was definitely too small and too early to conclude that there was not going to be an OA citation advantage. However, I agree completely that a null effect after three years does count as a failure to replicate the frequently reported OA citation advantage, because many of those reports were themselves based on samples and time-intervals of comparable size. What this means is that your three-year outcome would definitely qualify for inclusion in a meta-analysis of all the tests of the OA citation advantage-- whether their outcomes were positive, negative or null -- with a higher weighting (for sample size, interval and power) than the one-year study would have done. What it certainly does not mean, however, is that your null outcome has now demonstrated that all the positive outcomes were just a result of a self-selection artifact (which your randomization has now eliminated)! The reason -- to remind you again -- is that your study did not replicate the self-selection bias on its sample population (neither the 1-year sample nor the 3-year sample). Without that, it has definitely not been demonstrated that randomization eliminates the OA advantage. Your study has just shown (as a few other studies have already done) that in some samples, no OA citation advantage is found. These null studies have been a small minority, and their sample sizes have been small -- small not only in terms of the number of articles and journals sampled but (perhaps even more important) small in terms of the number of fields sampled. All of these variables can be duly taken into account in a meta-analysis, should someone take up Alma Swan 's call to do one: See Gene Glass's comments on this. Let's move to your new concern about generalizability: > The concern that tests for the OA citation advantage should be done across all fields is not a new one; and it continues to be a valid one. One cannot draw conclusions about all or even most unless the samples are representative of all or most fields (i.e., not just big enough and long enough, but broad enough).

That's the studies that are simply testing whether there is an OA citation advantage. But the comparison you are talking about is the comparison between self-selected and imposed OA. For that, you need to have a (sufficiently large, long, broad and representative) sample of self-selected and imposed OA. Then you have to see which hypothesis the outcome supports: According to the self-selection artifact hypothesis, the self-selection sample should show the usual OA citation advantage whereas the imposed sample should show no citation advantage (or a significantly smaller one). This would show whether (and to what degree) the OA citation advantage is the result of a self-selection bias. But if the outcome is that the OA citation advantage is the same whether the OA is self-selected or imposed, then this shows that the self-selection artifact hypothesis is incorrect. Your study has shown that in your sample (consisting of OA imposed by randomization), there is no OA citation advantage (only an OA download advantage). But it has not shown that there is any OA self-selection advantage either. Without that, there is only the non-replication of the OA citation advantage. Recall that the few other studies that have failed to replicate the OA citation advantage were all based on self-selected OA. So it does happen, occasionally, that a sample fails to find an OA citation advantage. To show that this is because the randomization has eliminated a self-selection bias requires a lot more. And meanwhile, we too have tested whether the OA advantage is an artifact of a self-selection bias, using mandated OA as the means of imposing the OA, instead of randomization. This allowed us to test a far bigger, longer, and broader sample. We replicated the widely reported OA citation advantage for self-selected OA, and found that OA imposed by mandates results in just as big an OA citation advantage. (Yassine Gargouri will soon post the standard error of the mean, based on our largest sample, for subsamples of the same size as yours; this will give an idea of the underlying variability as well as the probability of encountering a subsample with a null outcome. I stress, though, that this is not a substitute for a meta-analysis.)

Randomized OA is one way to test the effect of self-selection; but mandated OA is another. Both can also use multiple regression to control for the many other variables correlated with citations (and have done so), but mandates have the advantage of generating a much bigger, longer, and broader sample. (As mandates grow, it will become easier and easier for others to replicate our findings with studies of their own, even estimating the time it takes for mandates to take effect.) (I expect that the next redoubt of self-selectionists will be to suggest that there is a "self-selection bias" in mandate adoption, with elite [more cited/citeable] institutions more likely to adopt an OA mandate. But with a range that includes Harvard and MIT, to be sure, but also Queensland University of Technology and University of Minho -- the world's and europe's first institutions to adopt a university-wide mandate [Southampton's departmental mandate having been the first of all] it will be easy enough for anyone who is motivated to test these increasingly far-fetched bias hypotheses to control for each institution's pre-mandate citation rank: There are now over a hundredmandates to choose from. No need to wait for RCTs there...) Your last concern was about a self-selection control group: > > There were not a lot of cases of self-archiving in our dataset.

That's why I recommend using mandated OA instead. And you can find plenty of it in all fields, not just physics.

Another episode from my book. My wife loves this story, and we visited the courtyard near the Sample House at Rothamsted, where this experiment took place. Stephen J. Bensman LSU Libraries Louisiana State University Baton Rouge, LA 70803 USA notsjb at lsu.edu ...Fisher summarized his experimental methodology in The Design of Experiments, which was published in seven editions from 1935 to 1960. Yates and Mather (1963, pp.94 and 113) state that this was the first book explicitly devoted to this subject, and it amplified and extended the somewhat cursory and elementary exposition of this topic in Statistical Methods. Design of Experiments was also not mathematical but a discussion of the basic logical principles of experimentation, and it opens with the famous experiment conducted by Fisher shortly after he arrived at Rothamsted to test the assertion of a lady scientist, B. Muriel Bristol, that she could tell by the taste whether the tea or the milk had been poured into the cup first. Fisher's daughter, J. F. Box (1978, p. 134), reports in her biography of her father, that, although never reported, Bristol not only passed the test but so impressed the male scientist, who helped Fisher set up the experiment, that he married her. In his book entitled The Lady Testing Tea Salsburg (2001, pp. 1-8) reports that he was told in the late 1960s by H. Fairfield Smith, who had personally witnessed the experiment, that Bristol got every cup right, thereby ending any question of probability and possibly preventing Fisher from reporting this fact in his book. -------------- next part -------------- An HTML attachment was scrubbed...
