In this article, three types of time series of outgrow indices and one outgrow index matrix are introduced. Examples of these time series are given illustrating the newly introduced concepts. These time series expand the toolbox for citation analysis by focusing on a specific subnetwork of the global citation network. It is stated that citation analysis has three application areas: information retrieval, research evaluation and structural citation network studies. This contribution is explicitly placed among structural network studies. (C) 2011 Elsevier Ltd. All rights reserved.

By bookmarking and tagging articles, academic prosumers generate new information about resources, i.e. usage statistics and content description of scientific journals. Given the lack of global download statistics, the authors propose the application of social bookmarking data to journal evaluation. For a set of 45 physics journals all 13,608 bookmarks from CiteULike, Connotea and BibSonomy to documents published between 2004 and 2008 were analyzed. This article explores bookmarking data in STM and examines in how far it can be used to describe the perception of periodicals by the readership. Four basic indicators are defined, which analyze different aspects of usage: Usage Ratio, Usage Diffusion, Article Usage Intensity and Journal Usage Intensity. Tags are analyzed to describe a reader-specific view on journal content. (C) 2011 Elsevier Ltd. All rights reserved.

A random sample of 200 original research articles published between January and June 2004 was analysed from The Journal of Urology, Urology, European Urology and BJU International. Study information was abstracted by two independent reviewers and citation counts within 4 years of publication were collected using Web of ScienceTM. Study characteristics and citation rates were analysed using median and interquartile ranges (IQRs), and logistic regression analysis was used to evaluate which factors predicted greater citation rates. The overall median number of citations per published article was 6.0 (IQR 3-12). After univariate analysis, we found that study design, study topic, continent of origin and sample size were associated with greater median citation rates. In a multivariate linear regression model, study design and study topic (oncology) predicted increased citation rates. Randomized controlled trials were cited a median of 13.5 times and were the strongest predictor of citation rates with an odds ratio of 115.5 (95% confidence interval 9.4-1419.6). Citation rates are associated with study design and study topic in the urological literature. Authors may improve the impact of their work by designing clinical studies with greater methodological safeguards against bias.

Recently, new bibliometric indices and databases have been established, which may change the visibility of disciplines, institutions and individuals. This study examines the effects of the new indices on the visibility of Medical Informatics. Methods: By objective criteria, three sets of journals are chosen, two representing Medical Informatics and a third addressing Internal Medicine as a benchmark. The availability of index data (index coverage) and the aggregate scores of these corpora are compared for journal-related (Journal impact factor, Eigenfactor metrics, SCImago journal rank) and author-related indices (Hirsch-index, Egghes G-index). Correlation analysis compares the dependence of author-related indices. Results: The bibliometric visibility depended on the research focus and the citation database: Scopus covers more journals relevant for Medical Informatics than ISI/Thomson Reuters. Journals focused on Medical Informatics' methodology were negatively affected by the Eigenfactor metrics, while the visibility profited from an interdisciplinary research focus. The correlation between Hirsch-indices computed on citation databases and the Internet was strong. Conclusions: The visibility of smaller technology-oriented disciplines like Medical Informatics is changed by the new bibliometric indices and databases possibly leading to suitably changed publication strategies. Freely accessible author- related indices enable an easy and adequate individual assessment.

K.) Source: INDIAN JOURNAL OF PHARMACEUTICAL EDUCATION AND RESEARCH Volume: 45 Issue: 1 Pages: 1-7 Published: JAN-MAR 2011 Abstract: Research output (1947 to the end of 2009) from Indian pharmacy schools, (including departments of pharmaceutical sciences operating within universities) was gathered with the help of three online resources namely Scopus, and the official websites of Pharmacy Council of India (PCI) and All India Council for Technical Education (AICTE). AICTE provides a list of 1083 approved pharmacy colleges with a total of 62797 undergraduate and 8013 postgraduate admissions per year. Scopus lists a total of about 10680 publications with a total of 45010 citations (1947 to December 2009) from Indian pharmacy schools (excluding National Institute of Pharmaceutical Education and Research). The annual rate of increase in publications peaked at 30 to 40% between 2005 and 2007. Karnataka came first with more than 16% of the country's publications and over 13% of citations. The top ten schools bagged about 52% publications and 70% citations. The break-up data placed Harisingh Gour University, Sagar, on top for the maximum number of publications and Panjab University for the highest citations as well as citations per paper. Only 21 papers from Indian Pharmacy schools have a total citation count of more than 100. The current trend holds promise for rapid growth, although quality of publications has not yet become the priority of most researchers.

The so-called Impact Factor of journals, for example, is also an average. However, citation distributions are skewed and the average has the disadvantage that the number of publications is used in the denominator. Thus, a principal investigator has a higher average citation rate than s/he and her junior team together. However, the impact of the group is larger than that of the individual. In other words, size matters for impact. Leydesdorff & Bornmann (2011) therefore replaced averaging with integration of the citation curve, but not after qualifying the underlying publications in terms of their respective percentiles: a top-1% publication obtains 100 percent points whereas an average publication gets only 50 points. This rescaling from zero to hundred makes it possible to compare different sets and different citation distributions in terms of their impact. The results of the measurement can be used as input to non-parametric statistics which are, for example, available in SPSS. This website provides routines to compute I3 for a set of papers downloaded from the Web-of-Science (v5). First, this set can be organized in a relational database using ISI.exe . ISI.exe uses as input the download in the tagged format of the WoS which is available in the same folder and named "data.txt". The output is a set of databases (.dbf) which can be read using Excel or SPSS. For example, authors are organized into au.dbf and email addresses into em.dbf. (The various files are related in terms of the field "nr;" MSAccess can be used for relational database management.) The resulting files can be used by isi2i3.exe as input. This program will transform core.dbf into i3core.dbf, au.dbf into i3au.dbf, and cs.dbf into i3cs.dbf. The program may take a while; in the case of large files, one can perhaps leave it over night. When one uses the c-prompt, the routine either finishes (after a while) or provides an informative error message. The resulting files (e.g., i3core.dbf) are only different from the input files in a number of additional fields: the field i3f provides the value of i3 normalized as percentiles in relation to the set under study ("the field"), and i3j is normalized at the level of each journal. Analogously, r6f and r6j provide these values for the six percentile ranks used by the NSF: top-1%, top-5%, top-10%, top-25%, top-50%, and bottom-50%. Isi2i3.exe furthermore generates a number of summary tables that one can use: i3so.dbf summarizes the data after aggregation at the journal level ("so" for source); i3cntry.dbf for aggregation at the country level; i3city and i3inst at the city and institutional levels, respectively; i3au at the level of authors. These aggregations can also be made by using pivot tables in Excel or "Aggregate cases" in SPSS. Note that the results for authors and addresses are "integer counted": each record is counted as one, whereas fractional counting would imply attributing credit proportionally in the case of multi-authored papers. I3cs.dbf can be used as input for the generation of overlays to Google Maps strictly analagous to the procedures used by Leydesdorff & Persson (2010) and Bornmann & Leydesdorff (2011) . Instead of cities1.exe and cities2.exe, one uses i3cit1.exe and i3cit2.exe . Instead of inst1.exe and inst2.exe, one uses i3inst1.exe and i3inst2.exe . I3cit2.exe and i3inst2.exe directly produce the various output files among which ztest.txt. A third step is not needed; between the first and second step cities.txt or inst.txt has to be geocoded. An example is provided at http://www.leydesdorff.net/nano2011/nano2011.htm which shows a Google Map with the performance of cities worldwide in the field of 15 core journals of nanotechnology (Leydesdorff, in preparation).

The authors found that these measures consistently placed UK researchers among the best in the world. [1] Although opinions differ as to how reliable bibliometrics are as a sole measure of the quality and impact of research, [2, 3, 4] they are increasingly used to assess peer reviewed research outputs in contexts such as local research performance indicators, grant applications, and academic appraisal processes. The Higher Education Funding Council for England's current recommendation is that, because bibliometrics are unlikely to be free from distortion,[5] the forthcoming Research Excellence Framework subpanels will be asked to decide whether they wish to use citation information to inform their review of research outputs. Some may well do so. The decisions made by the framework will inform the distribution of public funds by the four UK higher education funding bodies and therefore influence the development of the evidence base, in one direction or another, that supports clinical decisions in the more than 300 million general practice consultations each year in the UK, which represent more than 95% of all NHS consultations. ...

Source: R & D MANAGEMENT Volume: 41 Issue: 3 Pages: 288-306 Published: JUN 2011 Abstract: Nanobiomedical science is a promising area in the application of nanotechnology. This paper profiles a group of 21 leading scientists in nanobiomedicine based on high publication rate and high citations. Comparisons with other researchers indicate that the leaders publish more in high impact journals and collaborate more extensively (team science). They reside most heavily in the United States and Western Europe. We compare their research publications using multiple indicators-Integration, Specialization and a Multidisciplinary Index. Relations among interdisciplinarity indicators generated support a three-factor model based on principles of diversity. We locate this research among the disciplines using science overlay mapping. Key term analyses, based on keywords and on natural language processing help profile the research emphases of these leading researchers. Such results could serve as leading indicators to help identify directions of future nanobio development.

Data were based on the online version of the Science Citation Index Expanded, Web of Science, from 1993 to 2008. Articles referring to water resources were assessed for many aspects, including distributions of source countries, institutes, words in the title, author keywords, and KeyWords Plus. The h-index was also calculated in terms of the characteristics of publications. Distributions of paper titles, the author's keywords, and KeyWords Plus at different periods were applied to evaluate research trends. The analysis showed that researchers paid most attention to groundwater and water quality parameters. Modeling and adsorption were the most popular techniques in water resources research. In addition, the relationship between the impact factor and h-index was significant for journals in the first group. The impact of the most cited articles each year were also discussed along with the article life information.

This paper aims to look at the calculation of the single publication h index and related performance measures. Design/methodology/approach - In this paper a web application is presented where the single publication h index and related performance measures (the single publication m index, h(2) lower, h(2) centre, and h(2) upper) can be automatically calculated for any publication indexed by Google Scholar. Findings - The use of the application is demonstrated by means of the citation performance of two publications. Originality/value - To the authors' knowledge this web application is the first instrument to automatically calculate the single publication h index and related performance measures based on Google Scholar data. This is a new service especially from the perspective of the related performance measures.

From fragment to fabric ? Dutch census data in a web of global cultural and historic information (CEDAR)? Project background This project builds a semantic data-web of historical information taking Dutch census data as a starting point. With such a web we will answer questions such as: - What kind of patterns can we identify and interpret in expressions of regional identity? - How to relate patterns of changes in skills and labor to technological progress and patterns of geographical migration? - How to trace changes of local and national policies in the structure of communities and individual lives? This project applies also a specific web-based data-model ? exploiting the Resource Description Framework (RDF) technology? to make census data inter-linkable with other hubs of historical socio-economic and demographic data and beyond. The project will result in generic methods and tools to weave historical and socio-economic datasets into an interlinked semantic data-web. Further synergy will be created by linking CEDAR to Data2Semantics, a COMMIT project. Job possibilities The project encompasses * one PhD project, titled ?Linked Open Data curation model in social science history ? the case of Dutch census data? - supervised by Professor Frank van Harmelen (VU Amsterdam). * one PhD project ?Theory and Practice of data harmonization in social history? - supervised by Professor Kees Mandemakers (Erasmus School of History, Culture and Communication, Erasmus University Rotterdam; IISH)) * one postdoc position for a candidate experienced in complex network analysis and visualization. The project will be coordinated by Dr Andrea Scharnhorst (DANS, e-humanities group). It is part of the Computational Humanities Programme of the KNAW, which will be hosted at the e-humanities group (ehumanities.nl) and in which further projects (with PhD students, postdoc?s and senior staff) in the area of computational and digital humanities will be carried out. For this project we seek candidates for all positions. The project runs over a period of four years. The specific requirements and details for application can be found in the attached job advertisements. The deadline for applications is August 29 for the PhD positions and October 1 for the PostDoc position.

Source: OPHTHALMOLOGY Volume: 118 Issue: 6 Pages: 1211-1214 DOI: 10.1016/j.ophtha.2010.10.023 Published: JUN 2011 Abstract: Purpose: To investigate the publishing trends of the top general clinical ophthalmic journals and to report: (1) the proportions of articles published in terms of ophthalmic subspecialty, (2) the study design used, (3) any changes in publishing trends, and (4) any differences in the quality of study design between the subspecialties. Design: Retrospective, database review. Participants: All original articles published in the top general, clinical ophthalmology journals from 2005 through 2009. Methods: All general, clinical ophthalmic journals were selected from the top 20 journals based on 2008 impact factor. All abstracts from original articles were reviewed, and the subject matter was recorded as belonging to 1 of the 11 ophthalmic subspecialties. After the content of the article was assigned, then the study design was recorded as one of the following: nonanalytic study, case-control or cohort study, randomized control trial, meta-analysis, laboratory science article, or systemic review. Main Outcome Measures: Subspecialty of the article and the study design used. Results: Seven journals were included, and 12 426 abstracts were reviewed. Articles relating to medical retina were the most prevalent (29.1%), and those relating to strabismus were the least prevalent (2.3%). Case-control or cohort studies comprised most study designs (40.1%), with meta-analyses comprising the least (0.3%). The mean number of articles per year was 2485 (standard deviation, 125.1), remaining stable over the study period. Medical retina articles were significantly more common in 2009 than in 2005 (chi-square, 11.2; P = 0.0008), whereas the proportion of oculoplastic articles was significantly reduced (chi-square, 16.9; P < 0.0001). Cataract and refractive surgery had the highest proportions of articles using the higher forms of study design (7.8%), and oculoplastics had the highest proportion of nonanalytic studies (64.5%). Conclusions: There are great differences across the specialty of ophthalmology in the subject matter of published literature, probably driven by recent advances in treatments. Medical retina is the subspecialty that is most represented in the literature, with strabismus being the least represented. Cataract and refractive surgery articles have the greatest proportion of higher- quality research strategies.

The aim of this report is to compare and comment on different bibliometric indicators related to some leading journals in rehabilitation, in order to provide further insights regarding their practical usefulness for Physical and Rehabilitation Medicine. Discussion: The commonly used Journal Impact Factor and the new SCImago Journal Rank indicator are measures of average "impact per paper". Other new measures show potentially useful complementarities with them and warrant further attention. For example, the Eigenfactor score represents a measure of total "citation impact" and seems sufficiently to express the "importance" of a journal. In fact, the information conveyed by the Eigenfactor score corresponds to a general consensus of journal status in Physical and Rehabilitation Medicine, as expressed by the European Consensus Committee on "International Rehabilitation Journals" and captured by a survey among European Physical and Rehabilitation Medicine researchers.

The results reveal that Germany, Netherlands, France and United Kingdom are no longer the leaders in the development of S&T, and the top positions have been taken by Northern European countries namely Finland, Denmark and Sweden. These results could give rise to the reshaping of European leadership in economic and social development, if Germany, France and the United Kingdom do not reverse their S&T investment trends of the past 20 years. The data not only indicate a change in the leading countries, but also the alteration of the positions of other countries in the European Space for Science. With the exception of Greece, Southern European countries have made considerable advances as have Czech Republic and Slovenia. As for (social) science productivity, it has been shown that the countries that are at the top of the S&T hierarchy are not necessarily those that publish most papers in WoS/JCR journals, but rather the contrary. This led to the conclusion that other indicators should be taken in consideration to analyse science productivity, including the orientation of academic reforms and the new models of universities governance. Science productivity is one of the tools used to implement this governance model which tends to manage all disciplines in the same way. Journal data bases are part of this new management and have a decisive role in the stratification of the European and global Science Space.

However, it shows more similarities to the social science output of other post-socialist countries than to the techno-scientifically developed European regions. The most recent bibliometric study of sociologists' publication productivity offers a more detailed picture of social science publication practices, as well as a specific disciplinary culture. Books form an essential part of sociological and SS&H output and thus they should also be included in any system of research productivity monitoring and evaluation. Web of Science (WoS) and Google Scholar (GS) bibliographical and citation data bases differ in covering sociological publications (especially books), which results in considerably different indicators of the quantity and visibility of published output. Empirical typology of visibility of sociologists' publications detects the difference between article and book visibility, as well as local and international visibility combined with WoS and GS coverage. The predictors of visibility types suggest that increasing the impact of Croatian sociological research should be based on stimulating publication by sociologists in both international books and journals.

Stephen J Bensman, Ph.D. LSU Libraries Lousiana State University Baton Rouge, LA 70803 USA The Wall Street Journal Health Mistakes in Scientific Studies Surge . By GAUTAM NAIK It was the kind of study that made doctors around the world sit up and take notice: Two popular high-blood-pressure drugs were found to be much better in combination than either alone. "There was a 'wow' reaction," recalls Franz Messerli, a New York doctor who, like many others, changed his prescription habits after the 2003 report. Unfortunately, it wasn't true. Six and a half years later, the prestigious medical journal the Lancet retracted the paper, citing "serious concerns" about the findings. The damage was done. Doctors by then had given the drug combination to well over 100,000 patients. Instead of protecting them from kidney problems, as the study said the drug combo could do, it left them more vulnerable to potentially life-threatening side effects, later studies showed. Today, "tens of thousands" of patients are still on the dual therapy, according to research firm SDI. View Full Image When a study is retracted, "it can be hard to make its effects go away," says Sheldon Tobe, a kidney-disease specialist at the University of Toronto. And that's more important today than ever because retractions of scientific studies are surging. Since 2001, while the number of papers published in research journals has risen 44%, the number retracted has leapt more than 15-fold, data compiled for The Wall Street Journal by Thomson Reuters reveal. Just 22 retraction notices appeared in 2001, but 139 in 2006 and 339 last year. Through seven months of this year, there have been 210, according to Thomson Reuters Web of Science, an index of 11,600 peer-reviewed journals world-wide. In a sign of the times, a blog called "Retraction Watch" has popped up to monitor the flow. Science is based on trust, and most researchers accept findings published in peer-reviewed journals. The studies spur others to embark on related avenues of research, so if one paper is later found to be tainted, an entire edifice of work comes into doubt. Millions of dollars' worth of private and government funding may go to waste, and, in the case of medical science, patients can be put at risk. At the Mayo Clinic, a decade of cancer research, partly taxpayer-funded, went down the drain when the prestigious Minnesota institution concluded that intriguing data about harnessing the immune system to fight cancer had been fabricated. Seventeen scholarly papers published in nine research journals had to be retracted. A researcher, who protests his innocence, was fired. View Full Image The Lancet Lancet editor Richard Horton said journals don't have adequate systems to investigate misconduct. View Full Image University Hospital Basel Swiss doctor Regina Kunz raised questions. In another major flameout, 18 research journals have said they are planning to retract a total of 89 published studies by a German anesthesiologist, many concerning a drug used for maintaining blood pressure during surgery. Authorities in Britain now are reviewing their usage guidelines as a result, and a prosecutor in Germany is conducting a criminal probe, which he says includes the possibility that data were fabricated. The anesthesiologist couldn't be reached for comment. Why the backpedaling on more and more scientific research? Some scientific journals argue that the increase could indicate the journals have become better at detecting errors. They point to how software has made it easier to uncover plagiarism. Others claim to find the cause in a more competitive landscape, both for the growing numbers of working scientific researchers who want to publish to advance their careers, and for research journals themselves. "The stakes are so high," said the Lancet's editor, Richard Horton. "A single paper in Lancet and you get your chair and you get your money. It's your passport to success." Retractions related to fraud showed a more than sevenfold increase between 2004 and 2009, exceeding the twofold rise in retractions related to mere error, according to an analysis published in the Journal of Medical Ethics. The analyst, Grant Steen, reached that conclusion after studying 742 medicine and biology papers that were withdrawn from 2000 to 2010. He said 73.5% were retracted simply for error but 26.6% were retracted for fraud. Another researcher, John Budd of the University of Missouri-Columbia, looked at roughly the same set of journals, though over a longer period, and also found the prevalence of scientific misconduct to be on the increase. The Lancet, founded in England in 1823, is among the world's most influential science publications. Just as research published in the Lancet can have a significant impact, so can the withdrawal of a Lancet paper, especially after it has been in the public domain and influencing scientific thought for years. In a notorious case, the Lancet last year retracted a study claiming a link between autism and the measles-mumps-rubella vaccine-12 years after it was published. In the intervening years, measles cases spiked in the U.K. as some parents refused to let their children be vaccinated. The lead investigator on the now-retracted study, Andrew Wakefield, was stripped of his license to practice medicine in Britain after authorities concluded that he had engaged in "serious professional misconduct." In an emailed response, Dr. Wakefield says he continues to defend his research, both "the findings and the conclusions." The Lancet issued just a single retraction notice from 2001 through 2005, but five in the next five years, according to Thomson Reuters. They included the one finding great promise in the combined use of two common blood-pressure drugs. The case illustrates both why it can take so long to pull a flawed study and the fallout that can result. One of the blood-pressure drugs, called an ACE inhibitor, relaxes blood vessels by preventing the body from creating a particular hormone. The other drug, called an ARB, acts on the same hormonal system but in a different way. High blood pressure can lead to kidney damage, and each of the two common drugs reduces a sign of impending kidney disease-the loss of protein through the urinary system. A Japanese researcher, Naoyuki Nakao, wondered if using both drugs at once would be even better at reducing this sign of kidney trouble. Sure enough, he reported that the combo was dramatically better than either drug alone. The Lancet published his study, dubbed "Cooperate," in January 2003. It jumped to the No. 2 spot among the most-cited papers published by the Lancet that month and created a buzz at medical conferences. Doctors increasingly prescribed the dual therapy. By 2008, about 140,000 patients in the U.S. were on it, according to SDI, the research firm. But the report struck some kidney-disease specialists in Switzerland as too good to be true. The report said patients given the drug combo saw a 76% decrease in protein loss, compared with 42% with one drug by itself and 44% with the other one alone. To see such a dramatic difference was unusual, says one of the Swiss doctors, Regina Kunz, who also was dubious of a particular statistical result in the study. "It was too perfect an effect. You wouldn't expect it with such a small sample size," says Dr. Kunz, director of the Academy of Insurance Medicine in Basel. "I think the peer reviewers should have caught it." She and three colleagues wrote to the Lancet in 2006 urging it to look into the matter. The Lancet's editor, Dr. Horton, says the journal passed their concerns on to Dr. Nakao in Japan, who responded with some "recalculations." The Lancet then passed all this material on an independent reviewer, who concluded in December 2006 that "it was impossible to tell whether data in the [original paper] were the result of fraud or incompetence," according to Dr. Horton. The Lancet tried to get Dr. Nakao to respond, "but he seemed to be prevaricating," according to Dr. Horton. Dr. Nakao, now at Isekai Hospital in Osaka, declined to be interviewed. In May 2008, the Lancet published a "letter of concern" by the Swiss doctors who had first written to the journal in 2006. The letter wondered whether certain inconsistencies were "only a case of extremely sloppy reporting or a hint towards more severe problems with the data." The Lancet now took the matter to another outside group, a U.K. nonprofit called the Committee on Publication Ethics. According to Dr. Horton, it decided the work was incompetent rather than fraudulent. The Lancet then wrote to a Japanese hospital where Dr. Nakao worked when he published his study. This hospital said it would do an investigation, but it would take six months. Pressure mounted. Dr. Messerli in New York, a cardiologist, wrote to the Lancet in mid-2009 arguing that it had a "moral obligation" to withdraw the paper. The Lancet said it would await the results of the hospital investigation. The hospital investigating committee examined medical records at another Japanese hospital where Dr. Nakao said he and his colleagues had done the research on 336 patients. But committee members "were not able to identify even a single patient who matched the contents of the paper," said Yutuka Sanada, the president of the hospital that investigated, called Showa University Fujigaoka Hospital, in Yokohama. "Dr. Nakao was not able to explain" this, he added, but "insisted that his paper was not a fabricated one." The investigation took until the summer of 2009, about a year after the Lancet first contacted the university hospital. "We should have raised the alarm with the university earlier," Dr. Horton now says. In October 2009, nearly seven years after the Lancet published the blood-pressure study and three years after questions were raised about it, the Lancet printed a retraction notice. It said the Japanese hospital investigation had concluded that the researchers hadn't obtained proper patient consent; that they hadn't obtained approval for the study from the ethics committee of the hospital where they said the research was done; and that the involvement of a statistician in the clinical trial couldn't be verified. The Lancet also pointed to a finding by the investigating committee that the trial wasn't "double-blind," a standard precaution in which neither researchers nor patients know who is getting what drug or placebo. Instead, the committee found that Dr. Nakao knew who was getting the drug combination and who wasn't-a situation many investigators consider tantamount to fraud. By the time the Lancet retracted the study, concerns were growing about potential harm to patients who got the combination therapy, except in certain rare cases where patients benefited. Data from clinical trials involving high blood pressure involving diabetes, coronary heart disease and advanced age persuasively showed that any small benefits of the combination therapy were easily outweighed by the side effects. "Even patients with uncomplicated essential hypertension were not entirely able to escape this fashionable trend" in treatment, Dr. Messerli in New York wrote in the European Heart Journal. As often happens, the original paper had inspired clinical research by others to test the dual therapy-studies that enrolled up to 36,000 patients, according to Dr. Steen, the analyst who did a study of retractions. "If there's a bad trial out there, there will be more flawed secondary trials, which put more patients at risk," he said. Dr. Kunz in Switzerland said the Lancet and its peer reviewers ought to have been more skeptical about the overly positive results and should have caught the statistical anomaly she noticed. "Journals all want to have spectacular results," she said. "Increasingly, they're willing to publish more risky papers." The Lancet's Dr. Horton dismisses that notion. He says journals hit by fraud and error are becoming more conservative about publishing provocative research. But he also says journals and research institutions don't have adequate systems in place to properly investigate misconduct. The apparent rise in scientific fraud, said Dr. Horton "is a scar on the moral body of science." -Miho Inada contributed to this article. -------------- next part -------------- An HTML attachment was scrubbed...

Scientific Retractions: A Growth Industry? August 11, 2011 at 4:38 AM The Wall Street Journal has an interesting article based on data from Thomson Reuters on the frequency of retracted papers. It seems to be increasing dramatically: Since 2001, while the number of papers published in research journals has risen 44%, the number retracted has leapt more than 15-fold, data compiled for The Wall Street Journal by Thomson Reuters reveal. Just 22 retraction notices appeared in 2001, but 139 in 2006 and 339 last year. Through seven months of this year, there have been 210, according to Thomson Reuters Web of Science, an index of 11,600 peer-reviewed journals world-wide. They mention Retraction Watch, as well they should. But ten years ago, would there have been enough new material to keep that blog running? Pharmalot has some more from its founder about what might be going on. There are, of course, more journals than ever these days, and many of them are junk. But it's not the bottom-tier journals that are driving this trend, I'd think, since honestly, when does anyone ever retract a paper in one of them? Consistent with that view, this bar chart of PubMed retractions by journal is heavily weighted towards the big dogs. A lousy or nonreproducible paper in one of the top journals is more likely to be of enough interest to attract attention, but one in J. Whatever will just sit there. No, when you look at this chart, it appears that retractions-per-papers-published have been climbing, so the answer must be some combination of more mistakes, more fraud, or better policing. Retractions due to fraud seem to be where most of the growth is, according to this study, so that takes us down to the latter two explanations. Software has definitely made the lazier sorts of fraud easier to detect, automatically flagging copy-and-paste hack jobs. But those aren't the kinds of things that show up in the better journals, are they? We may be seeing a mix of greater incentive to commit fraud and a rise in skepticism among readers. There have been enough cases, enough highly-publicized retractions and scandals, that more people may be willing to wonder if some exciting new result is true at all. That's not a bad thing. The rise in fraud is a bad thing, but a corresponding rise in scrutiny is the only thing that's going to cure it. There are always a few pathological types out there that kind of know that they're going to get caught and kind of don't care. Those we shall always have with us, and not much is going to discourage them. But as for the rest of the fraudsters, the thought that they have a better chance of being found out and punished should give them something to think about. Dana L.

An effect of their use, it argued, is to stifle diversity and constrict scholarly innovation. A monoculture is fostered in which a preoccupation with shoehorning research into a form prized by elite, US-oriented journals overrides a concern to maintain and enrich the diversity of topics, the range of methods and the plurality of perspectives engaged in business and management research. Use of a particular journal list, such as the one prepared by the Association of Business Schools (ABS), can come to dominate the scholarly terrain of a particular discipline with consequences that can be damaging to funding as well as to research culture.

C.) Source: ORGANIZATION Volume: 18 Issue: 4 Pages: 449-466 DOI: 10.1177/1350508411403531 Published: JUL 2011 Abstract: The simplicity and apparent objectivity of the Institute for Scientific Information's Impact Factor has resulted in its widespread use to assess the quality of organization studies journals and by extension the impact of the articles they publish and the achievements of their authors. After describing how such uses of the Impact Factor can distort both researcher and editorial behavior to the detriment of the field, I show how extreme variability in article citedness permits the vast majority of articles-and journals themselves-to free- ride on a small number of highly-cited articles. I conclude that the Impact Factor has little credibility as a proxy for the quality of either organization studies journals or the articles they publish, resulting in attributions of journal or article quality that are incorrect as much or more than half the time. The clear implication is that we need to cease our reliance on such a non-scientific, quantitative characterization to evaluate the quality of our work.

This is seen as a conspicuous flaw of such exercises and calls have been made to find a remedy. Here a simple, systematic solution is proposed based upon a mathematical model for the relationship between research quality and group quantity. This model manifests both the Matthew effect and a phenomenon akin to the Ringelmann effect and reveals the existence of two critical masses for each academic discipline: a lower value, below which groups are vulnerable, and an upper value beyond which the dependency of quality on quantity reduces and plateaus appear when the critical masses are large. A possible normalization procedure is then to pitch these plateaus at similar levels. We examine the consequences of this procedure at RAE for a multitude of academic disciplines, corresponding to a range of critical masses.

Separate analyses were made for language and linguistics and for literature components of each language in the study. The study covered both publications directed at a national or international scholarly output and publications destined for the general public. The latter accounted. for 8-73% of the output, and were particularly important in literature output. Publication and citation behavior differed considerably between language and linguistics on the one hand and literature on the other hand, calling for a tailored design of monitoring studies in both fields. In publications directed at scholars, the national language did not dominate. In literature fields, the language of the object of study was most important, while in language and linguistics, the object language was not always more important than English. The study indicates that both journal articles and book output need to be included in bibliometric evaluation. Citation impact analysis is shown to be informative in bibliometric assessment in this field, especially when a five- year citation window is used.

Developments in research are compared with research policy developments, focusing on the use of performance indicator tools from new public management. Two examples from Denmark and the UK describe how this thinking has gained ground in the overall management of the allocation of basic funds for university research. Based on the analysis of examples and research policy developments, the article argues that existing indicators are lagging behind and need to be updated as they do not adequately reflect the politically desired Mode 2 features of the public research system. Consequently, there is a need to develop and implement new Mode 2 indicators for measuring and managing public research. In conclusion, the article suggests possible new indicators of Mode 2-oriented research. These indicators need to be further developed and can be seen as an agenda for further research.

(Article, English) AUTHOR: Zemp, S; Stauffacher, M; Lang, DJ; Scholz, RW SOURCE: JOURNAL OF TRANSPORT GEOGRAPHY 19 (4). JUL 2011. p.670-679 ELSEVIER SCI LTD, OXFORD ABSTRACT: The classification of railway stations is a potentially powerful tool for strategic transport and land use planning. Existing classifications rely strongly on the indicator "passenger frequency", which focuses on transport related issues, blending performance with preconditions at a given site. We argue that a classification system for strategic planning should focus on the demands and conditions of the site within which the railway station must function, i.e. system context. Here, we present such a classification system: a cluster analysis of the 1700 Swiss railway stations relying solely on context factors. The resulting classes vary primarily in density (of land use and transport services) and use (commuting, leisure time, tourism). Common geographic patterns and class- specific dynamics are discernable. These results indicate that classification based on the relevant demands and conditions given by context leads to clearly interpretable classes and supports multi-perspective strategic planning for railway stations. The systematic approach allows for a better understanding of the interrelations between railway stations and their context. (C) 2010 Elsevier Ltd. All rights reserved.

The results of this work reveal that the literature on the algae and bio-energy has grown exponentially during this period reaching 717 papers in total. Most of document type is in the form of journal articles, reviews, and proceedings, constituting 98% of the total literature and English is the predominant language (97.6%). USA, China, Germany, and England are the four biggest contributing countries on the algae and bio-energy literature publishing, 26%, 8%, 8%, and 8% of the sample, respectively. The Chinese Academy of Sciences is the largest institutional contributor publishing 2.6% of the papers. The most publishing four authors are Wilhelm (13 papers) followed by Wu (15 papers), Mimuro (10 papers), and Zhao (9 papers). "Bioresource Technology" is the most publishing journal with 24 published papers, followed by "Journal of Applied Phycology" (17 papers). and "Biotechnology and Bioengineering" (15 papers). "Biotechnology & Applied Microbiology" is the subject area with 24.3% of the sample published. This is followed by "Energy & Fuels" (16.3%), "Marine & Freshwater Biology" (14.2%), and "Environmental Sciences" (12.3%). The total number of citations is 11,079, giving a ratio for the "Average Citations per Item" as 15.45 and "H-index" as 52. A list of most-cited 25 authors is produced and Chisti (2007) receives 320 citations with 80 total average citations per year. This paper is followed by Lewis and Nocera (2006; 296 citations). Demirbas (2001; 187 citations). Chisti (2007) has the highest impact on the literature on the algae and energy with total average citations per year of 80. This is followed by Lewis and Nocera (2006, 59.8 annual citations) and Chisti (20(18, 41 annual citations). An analysis of the citing papers shows the impact of the research on the algae and bio-energy for the related academic disciplines. This provides further incentives for all the stakeholders of the research on the algae and energy, but especially for the researchers and their institutions and their countries to do more research in this area. The results of this first ever such study of its kind show that the scientometric analysis has a great potential to gain valuable insights into the evolution of the research the on algae and bio- energy as in the case of new emerging technologies and processes such as nanoscience and nanotechnology complementing literature reviews, content analysis and metaanalysis research techniques.

The most heated question has concerned the scientific status of computing. Some consider computing to be a natural science and some consider it to be an experimental science. Others argue that computing is bad science, whereas some say that computing is not a science at all. This survey article presents viewpoints for and against computing as a science. Those viewpoints are analyzed against basic positions in the philosophy of science. The article aims at giving the reader an overview, background, and a historical and theoretical frame of reference for understanding and interpreting some central questions in the debates about the disciplinary identity of computer science. The article argues that much of the discussion about the scientific nature of computing is misguided due to a deep conceptual uncertainty about science in general as well as computing in particular.

Here, we provide a new evaluation of journals devoted to entrepreneurship, plus more general journals that publish entrepreneurship articles. The evaluation uses a citation- based model to rate journals. This model overcomes some limitations inherent in the widely known "JIFs" approach. The model is used to derive ratings that shows the relative influences of established journals that publish research dealing with the entrepreneurship domain. In addition to being a way to gauge the influence that a particular journal has had on this domain, a journal's rating can serve as an early proxy for measuring the influence of individual entrepreneurship articles that have yet to have an opportunity to accumulate citations.

More recently, scholars have begun to investigate more fully the structures and processes that impede the production of knowledge. This article draws on interviews conducted with 41 academic researchers to present a phenomenological examination of "forbidden knowledge''-a phrase that refers to knowledge considered too sensitive, dangerous, or taboo to produce. Forbidden knowledge has traditionally been understood as a set of formal controls on what ought not be known. We argue that the social processes that create forbidden knowledge are embedded in the everyday practices of working scientists. The narrative legacies of past controversies in science are of particular importance, as they serve as a tool that working scientists use to justify, construct, and hide their acceptance of forbidden knowledge. As a result, the precise contents of forbidden knowledge are fluid, fuzzy, essentially contested, specialty specific, locally created, and enforced.

Author(s): Hallsten, M (Hallsten, Martin)1,2 Source: BRITISH JOURNAL OF INDUSTRIAL RELATIONS Volume: 49 Issue: 3 Pages: 537-559 Published: SEP 2011 Abstract: In this article, I investigate the relation between economic inequality and the decision to take up studies at the tertiary level late in life. Who exactly decides to enrol? Is it advantaged or disadvantaged groups in terms of current earnings rank, occupation, unemployment experience and social origin? Using unique register data of university applications and discrete time hazard regression models, the results show the likelihood of a late entry to be especially high for individuals who are disadvantaged to a moderate extent in terms of current earnings rank and also with some unemployment experience. Class differences in the transition to tertiary education decline with age. This suggests, with a moderate amount of simplification, that lifelong learning tends to promote both intra- and intergenerational equality.

Among existing ranking algorithms, link analysis based algorithms have been proved to be effective for ranking documents retrieved from large-scale text repositories such as the current Web. Recent developments in semantic Web raise considerable interest in designing new ranking paradigms for various semantic search applications. While ranking methods in this context exist, they have not gained much popularity. in this article we introduce the idea of the "Rational Research" model which reflects search behaviour of a "rational" researcher in a scientific research environment, and propose the RareRank algorithm for ranking entities in semantic search systems, in particular, we focus on elaborating the rationale and implementation of the algorithm. Experiments are performed using the RareRank algorithm and the results are evaluated by domain experts using popular ranking performance measures. A comparison study with existing link- based ranking algorithms reveals the benefits of the proposed method. (C) 2011 Elsevier Inc. All rights reserved.

"Going beyond Impact Factors: A survey-based journal ranking by agricultural economists" J. of Agricultural Economics 62(3):710-732 September 2011 Message-ID: E-mail Address: Roland.Herrmann at agrar.uni-giessen.de TITLE : Going Beyond Impact Factors: A Survey-based Journal Ranking by Agricultural Economists Author(s): Herrmann, R (Herrmann, Roland)1; Berg, E (Berg, Ernst)2; Dabbert, S (Dabbert, Stephan)3; Pochtrager, S (Poechtrager, Siegfried)4; Salhofer, K (Salhofer, Klaus)5 Source: JOURNAL OF AGRICULTURAL ECONOMICS Volume: 62 Issue: 3 Pages: 710-732 Published: SEP 2011 Abstract: A consistent and comprehensive ranking of journals relevant for agricultural economists cannot rely on impact factors for at least two major reasons: (i) the scientific database by Thomson Reuters, on which the standard impact factor is based, includes only a very limited number of relevant journals; (ii) the standard impact factor cannot be compared across research fields of different sizes. Survey-based journal rankings may overcome these problems. We report on such a survey-based ranking initiated by the Agricultural Economics Associations of Germany and Austria. Results of the ranking and a classification of journals, i. e. a rating, are provided for 160 selected journals. Scientific quality is assessed by an index based on the researchers' perception of the quality standards of each journal and of the quality of its published articles. The survey-based ranking allows a much more comprehensive and consistent ranking than the impact factor, as specific agricultural economics journals can be directly compared with neighbouring economic and interdisciplinary journals to which agricultural economists submit their work. The low impact factors of core agricultural economics journals are put into perspective. The scientific quality of the top agricultural economics journals is assessed as being rather high and above most of the relevant interdisciplinary journals from agricultural and food sciences that are typically characterised by higher impact factors. Agricultural economists' perceptions on the scientific quality of the journals vary more across journals than perceptions of their relevance.

We hypothesized that there were differences among the anesthesiology journals in both the total number of self-citations and the proportion of self-citations to the total number of references in each manuscript for the years 2005 and 2010. METHODS: We conducted a review of a sample of manuscripts from 2005 and 2010 to examine the number and rate of self-citations. As a secondary analysis, we reviewed impact factor (IF), rate of self-referencing, and contribution of self-citations to IF in the population of manuscripts published in 8 anesthesia journals between 2000 and 2009 using the ISI Journal Citation Reports. RESULTS: The number (P < 0.0001) and rate (P < 0.0001) of self-citations among the different journals were significantly different in 2005, with similar results for 2010 in the number (P < 0.0001) and rate (P = 0.0002) of self- citations. The mean range of number of self-citations ranged from 0.45 (95% confidence interval [CI], 0.06 to 0.84) to 3.95 (95% CI, 2.2 to 5.7) in 2005 and from 0.25 (95% CI, -0.05 to 0.55) to 4.5 (95% CI, 2.2 to 6.9) in 2010. On a per-journal basis, no difference in the number of self-citations was noted between 2005 and 2010. Analysis of the ISI Journal Citation Reports from 2000 to 2009 suggested a general decline in the contribution of self-cites to the IF over time for the aggregate journals (Spearman correlation coefficient (Rs) - 0.25 (95% CI, -0.45 to -0.03), P = 0.02), with the exception of the journal in question (Rs = 0.59 (95% CI, -0.1 to 0.88), P = 0.05). Positive correlations were found between self-cited rate and IF (Rs 0.52, 95% CI, 0.34 to 0.66, P < 0.0001), percentage of self-cites to years used in IF calculation and IF (Rs 0.41, 95% CI, 0.21 to 0.58, P < 0.0001), and delta-IF and IF (Rs 0.89, 95% CI, 0.84 to 0.93, P < 0.0001). CONCLUSION: Although the number and rate of self-citations differed among anesthesia journals, the contribution of self-citation to IF has declined over time for most anesthesia journals. These results suggest periodic reassessment may be important to ensure that the publication process remains transparent and impartial to bias.

One of my PhD students and I are looking at how systems might be developed using software services (SOA etc.). Needless to say, we have identified lots of literature about software services and their properties, but very little about how to model these and how to model the interactions between them. Our purpose is actually reasonably concrete, in that we are looking at service design for a real application, using some work that our Energy Engineers have been doing with Small Scale Energy Zones (SSEZs) to create a case study. We have (or more accurately, my student has) conducted a systematic review to look at the properties of SOAs that we need to model -- what we would like to be able to do is to describe these properties with a set of 'box and line' notations in order to be able to develop our ideas about design solutions. There are one or two notational forms that have been suggested (for example, in a book by Thomas Erl) but these are mostly more suitable for illustrating concepts in a textbook rather than for developing design solutions. I'm aware of some papers that critique notations (including one by Daniel Moody that appeared at the end of 2009) and we turned some up in the process of performing a systematic review of empirical studies of the UML, but while these can be used retrospectively, they don't help with developing new notations. Do you know of any work that provides guidelines on notation development, or at least, describes an example of a development please?

In contrast, cited colleagues rarely receive more than 3 citations. This is what we call the self-citation bias: the preference researchers have to refer to their own work when they guide readers to the relevant literature. We argue that this finding is difficult to understand within the traditional, science-based view, which says that reference lists are there to help the reader. It is more easily understood within a social view of reference lists which argues that scientists form groups and that reference lists partly reflect well-known phenomena in social psychology and group dynamics. Within this view, the self-citation bias is a self-serving bias motivated by self-enhancement and self-promotion.

The overlays using the ISI Subject Categories available from http://www.leydesdorff.net/overlaytoolkit operated on the field "SC" in WoS4, but this field was changed into "WC" (that is, Web-of-Sci categories) in WoS 5. This is now corrected in ISI.exe. The output file is still called sc09.vec (in order not to generate confusion) and directly applicable in Pajek to the map for 2009. (In the new map for 2010-still under construction-we will call the input file for Pajek wc10.vec.) 2. Benjamin Schwalb was so kind to list how one can transform Scopus output to the tagged format of WoS data. I did not test this routine for other fields than he used.

Methods: Multiple raters blindly assessed two samples of faculty (1) tenure-track faculty at institutions listed in the U.S. News and World Report top 10 (n = 337) and (2) tenure- track editorial board members of 5 highly ranked social work journals (n = 215). Results: Intraclass correlation coefficients for h-index values among the multiple raters ranged from .83 to .92, indicating good reliability. For faculty at top 10 institutions, mean estimated h-index values were 3.97 (SD = 2.87) for assistant professors; 8.59 (SD = 3.72) for associate professors; and 16.14 (SD = 8.35) for full professors. Values for editorial board members were generally similar. Conclusions: These are the first such published data; further research is needed.

The effective organization of journals can help reveal the thematic contents of journals and thus make them more user-friendly. In this study, the Self-Organizing Map (SOM) technique was employed to visually analyze the 60 library and information science-related journals published from 2006 to 2008. The U-matrix by Ultsch (2003) was applied to categorize the journals into 19 clusters according to their subjects. Four journals were recommended to supplement library collections although they were not indexed by SCI/SSCI. A novel SOM display named Attribute Accumulation Matrix (AA-matrix) was proposed, and the results from this method show that they correlate significantly with the total occurrences of the subjects in the investigated journals. The AA-matrix was employed to identify the 86 salient subjects, which could be manually classified into 7 meaningful groups. A method of the Salient Attribute Projection was constructed to label the attribute characteristics of different clusters. Finally, the subject characteristics of the journals with high impact factors (IFs) were also addressed. The findings of this study can lead to a better understanding of the subject structure and characteristics of library/information-related journals.

Design, Setting, and Participants: Biographical information from current faculty members of neurology training programs in the United States was obtained through an Internet-based search of departmental Web sites. Collected variables included medical school attended, residency program completed, and current academic rank. For each faculty member, ISI Web of Science and Scopus h-indices were also collected. Results: Data from academic neurologists from 120 training programs with 3249 faculty members were collected. All data regarding training program and medical school education were compiled and analyzed by the institution from which each individual graduated. The 20 medical schools and neurology residency training programs producing the greatest number of graduates remaining in academic practice and the mean h-indices are reported. More medical school graduates of the Columbia University College of Physicians and Surgeons chose to enter academic neurology practice than the graduates of any other institution. Analyzed by residency training program attended, New York Presbyterian Hospital (Columbia University), Mayo Clinic (Rochester, Minnesota), and Mount Sinai Medical Center (New York, New York) produced the most graduates remaining in academics. Conclusions: This retrospective, longitudinal cohort study examines through quantitative measures the academic productivity and rank of academic neurologists. The results demonstrate that several training programs excel in producing a significantly higher proportion of academically active neurologists.

Analyzed aspects covered publication outputs, publication patterns, and international and inter-institutional collaborations of the two universities. The two universities were in the same scale based on the number of publications. Articles from electrical and electronic engineering dominated the other articles in NTU while PKU researchers published a great number of articles in the basic science fields. Material science was the new field for these two universities. The USA had the greatest number of collaborated articles accounting for 15% and 12% of total articles with NTU and PKU respectively. Article impact followed a decreasing order of international collaboration, inter-institutional collaboration, and independent articles for both universities. PKU articles had higher visibility. In addition, the Essential Science Indicators were applied to investigate the research activities of NTU and PKU.

The 402 citations were retrieved from Social Science Citation Index (SSCI) via DIALOG. The findings show that the annual growth of this literature is unstable. These papers come from many disciplines indicating that terrorism has not yet developed into a specialty. The literature is dispersed, mostly thin, in 139 journals with no identifiable core. Single-author and English language publications are dominant. Most of the papers originate in the U.S.A and U.K. It is suggested that indexing should be expanded to cover journals published in developing countries and their languages. It is also suggested that studies on larger samples should be conducted to identify rates of growth, core authors, core journals, and changes in research topics.

Very few authors publish in these top journals. They are said to be the best few, on the assumption that skew indicates quality. Yet, skew is natural in any distribution and would occur in the absence of all quality. Peer review is supposed to ensure that this cannot happen, but pressure to publish in top journals puts demands on the peer review system it was never intended to bear. One result is that the skewed few tend to be the same few. We look at how this is arranged. We investigate the citation of the skewed few. We find much self citation, mutual citation and group citation. This behaviour is encouraged by the paramount importance of the journal impact factor. The article looks at how this indicator has been contrived for commercial rather than academic reasons, and considers some of the consequences.

We obtained a high correlation coefficient between the IF 2006 and h-index 2006. The rating of journals starting from the h-index may represent a complementary alternative to the rating based on the IF. The h-index rating proposes a categorization of journals making it possible to create classes of journals with the same h-index.

Data were based on the online version of Science Citation Index Expanded from 1992 to 2009. Articles referring to climate change were assessed by distribution of source countries, source institutes, paper titles, author keywords, KeyWords Plus, abstracts, and the most cited articles in these years. By synthetic analysis of the four kinds of keywords, it was concluded that the items "temperature", "environment", "precipitation", "greenhouse gas", "risk", and "biodiversity" will be the foci of climate change research in the 21st century, while "model", "monitoring", and "remote sensing" will continue to be the leading research methods. A novel method, "phylogeography", may have a strong application potential in the near future. (C) 2011 Elsevier B.V. All rights reserved.

Despite a 61% reduction in citation counts from the peak year (1989: Year 4) to the final year (2010: Year 25), many of these articles were still being cited 25 years after they had been published. When the sample was divided into four categories of impact using the total citation counts for each article-low impact (0-24 citations), moderate impact (25-99 citations), high impact (100-249 citations), and very high impact (250-1763 citations)-the yearly citation counts of low to high-impact articles peaked earlier and displayed a steeper decline than the yearly citation counts of very high- impact articles. Using 5 or more citations a years, 10 or more citations a year, and 20 or more citations a year as markers of moderate-impact, high- impact, and very high-impact articles, respectively, and using the most cited articles in a jou! rnal during the first 5 years of the follow-up period as indicators of high impact and very high impact showed promise of predicting impact over the entire 25-year period.

Link counts have been available from commercial search engines for over a decade but this was set to end by early 2012 and so a replacement is needed. This article compares link counts to two alternative methods: URL citations and organization title mentions. New variations of these methods are also introduced. The three methods are compared against each other using Yahoo!. Two of the three methods (URL citations and organization title mentions) are also compared against each other using Bing. Evidence from a case study of 131 UK universities and 49 US Library and Information Science (LIS) departments suggests that Bing's Hit Count Estimates (HCEs) for popular title searches are not useful for webometric research but that Yahoo!'s HCEs for all three types of search and Bing's URL citation HCEs seem to be consistent. For exact URL counts the results of all three methods in Yahoo! and both methods in Bing are also consistent. Four types of accuracy factors are also introduced and defined: search engine coverage, search engine retrieval variation, search engine retrieval anomalies, and query polysemy.

JUL 2011. p.658-673 WILEY-BLACKWELL, MALDEN SEARCH TERM(S): JOURNALS item_title KEYWORDS+: DEPARTMENTS; PRODUCTIVITY; RANKINGS; US ABSTRACT: We describe the evolution of subject areas published in economics over four decades and calculate the percentage of articles published in each Journal of Economic Literature (JEL) subject category, with and without weighting by Eigenfactor.com's Article Influence (AI). Finance, Development, and Industrial Organization have seen their share of total articles rise over the past four decades while Microeconomics, Macroeconomics, and Labor have seen their share fall. We use JEL codes to define specialty journals and find that more specialty journals tend to increase the overall percentage share for that subject. This effect is ambiguous when re-weighted by AI.

This is the case for (in total) 75 examined researchers from the fields of mathematics (Fields medalists), physics, chemistry, and physiology or medicine (Nobel laureates). We study several indicators for these researchers, including the h-index, total number of publications, average number of citations per publication, the number (and fraction) of uncited publications, and their interrelations. The most remarkable result is a positive correlation between the h-index and the number of uncited articles. We also present a Lotkaian model, which partially explains the empirically found regularities.

Current commonly used methods include impact factor for journals, PubMed's clinical query filters and machine learning-based filter models for articles, and PageRank for websites. Previous work has focused on the average performance of these methods without considering the topic, and it is unknown how performance varies for specific topics or focused searches. Clinicians, researchers, and users should be aware when expected performance is not achieved for specific topics. The present work analyzes the behavior of these methods for a variety of topics. Impact factor, clinical query filters, and PageRank vary widely across different topics while a topic-specific impact factor and machine learning- based filter models are more stable. The results demonstrate that a method may perform excellently on average but struggle when used on a number of narrower topics. Topic-adjusted metrics and other topic robust methods have an advantage in such situations. Users of traditional topic-sensitive metrics should be aware of their limitations. (C) 2011 Elsevier Inc.

Background: Our study purpose was to assess the predictive validity of reviewer quality ratings and editorial decisions in a general medicine journal. Methods: Submissions to the Journal of General Internal Medicine (JGIM) between July 2004 and June 2005 were included. We abstracted JGIM peer review quality ratings, verified the publication status of all articles and calculated an impact factor for published articles (Rw) by dividing the 3-year citation rate by the average for this group of papers; an Rw > 1 indicates a greater than average impact. Results: Of 507 submissions, 128 (25%) were published in JGIM, 331 rejected (128 with review) and 48 were either not resubmitted after revision was requested or were withdrawn by the author. Of 331 rejections, 243 were published elsewhere. Articles published in JGIM had a higher citation rate than those published elsewhere (Rw: 1.6 vs. 1.1, p = 0.002). Reviewer quality ratings of article quality had good internal consistency and reviewer recommendations markedly influenced publication decisions. There was no quality rating cutpoint that accurately distinguished high from low impact articles. There was a stepwise increase in Rw for articles rejected without review, rejected after review or accepted by JGIM (Rw 0.60 vs. 0.87 vs. 1.56, p < 0.0005). However, there was low agreement between reviewers for quality ratings and publication recommendations. The editorial publication decision accurately discriminated high and low impact articles in 68% of submissions. We found evidence of better accuracy with a greater number of reviewers. Conclusions: The peer review process largely succeeds in selecting high impact articles and dispatching lower impact ones, but the process is far from perfect. While the inter-rater reliability between individual reviewers is low, the accuracy of sorting is improved with a greater number of reviewers.

AUG 1 2011. p.216-219 WILEY-BLACKWELL, MALDEN SEARCH TERM(S): BIBLIOMETR* item_title KEYWORDS: surgical oncology; research; translational; cancer; general surgery KEYWORDS+: COLORECTAL LIVER METASTASES; INTERNATIONAL MULTIINSTITUTIONAL ANALYSIS; HEPATIC RESECTION; CHEMOTHERAPY; PUBLICATIONS; SURGERY; ORIGIN ABSTRACT: Objective: To evaluate the distribution and scope of surgical research in Australia relating to malignant diseases in the field of surgery. Method: Surgical publications relating to adult malignant diseases originating from Australia were identified from a systematic literature examination using PubMed during a 12-year period between 1998 and 2009. The origin of the article, journal impact factor (IF), type of research and its subspecialty discipline were recorded. Results: Over a 12-year period, 1,132 papers were published in various journals at a median annual rate of 98 papers. Four hundred eighty-five (43%) papers arose from institutions in New South Wales, 225 (20%) papers from Victoria, 150 (13%) papers from South Australia, 106 (9%) papers from Western Australia, and 77 (7%) papers from Queensland. The mean IF was 3.22 (SD = 2.5). Papers were most commonly published in journals including the ANZ Journal of Surgery (n = 237, 21%), Annals of Surgical Oncology (n = 50, 4%), British Journal of Surgery (n = 38, 3%), and Diseases of the Colon and Rectum (n = 36, 3%). The mean IF of papers published per year ranged from 2.55 to 3.87. The most number of papers were published in the fields of urological oncology (n = 103, 9%), hepatopancreaticobiliary oncology (n = 144, 13%), breast oncology (n = 174, 15%), and colorectal oncology (n = 222, 20%). Conclusion: Bibliometric findings of this review suggest that there is a growth in high scientific research publications in the field of surgical oncology in Australia, indicating an interest in this discipline. This research trend may impact on the national research strategy for clinical cancer control. J. Surg. Oncol. 2011;104:216-219. (C) 2011 Wiley-Liss, Inc.

Survey-based journal rankings may overcome these problems. We report on such a survey-based ranking initiated by the Agricultural Economics Associations of Germany and Austria. Results of the ranking and a classification of journals, i. e. a rating, are provided for 160 selected journals. Scientific quality is assessed by an index based on the researchers' perception of the quality standards of each journal and of the quality of its published articles. The survey-based ranking allows a much more comprehensive and consistent ranking than the *impact factor*, as specific agricultural ! economics journals can be directly compared with neighbouring economic and interdisciplinary journals to which agricultural economists submit their work. The low impact factors of core agricultural economics journals are put into perspective. The scientific quality of the top agricultural economics journals is assessed as being rather high and above most of the relevant interdisciplinary journals from agricultural and food sciences that are typically characterised by higher impact factors. Agricultural economists' perceptions on the scientific quality of the journals vary more across journals than perceptions of their relevance.

An alternative citation-based ranking scheme is applied to the accounting and finance journals to highlight some loopholes in the abandoned ARC scheme and provide some suggestions for how to proceed with ERA 2012. By re-ranking journals according to their citation indices, it is demonstrated that the ARC ranking placed a large number of journals where they do not belong. As a result, the ARC scheme induced some adverse behavioural changes with respect to preferred publication outlets.

A 30% random sample of abstracts presented at the 2006 Annual Meeting of SSWR was reviewed. To determine publication status of the presentations, the authors conducted searches using Google Scholar, PubMed, PsycINFO, and Social Work Abstracts, in addition to reviewing faculty pages and curriculum vitae (CVs). The authors recorded information about the published articles including the journal title, *impact factor*, year, and authors. Forty-three percentage (95% CI = [34.5%, 51.9%]) of presentations were published in a peer-reviewed journal. Twenty-eight percentage (95% CI = [20.9%, 36.7%]) of publications were in a journal with an ISI *Impact Factor* (M = 1.32). The number of presentation authors was not associated with a subsequent publication. No differences were observed by type of p! resentation.

Current commonly used methods include *impact factor* for journals, PubMed's clinical query filters and machine learning-based filter models for articles, and PageRank for websites. Previous work has focused on the average performance of these methods without considering the topic, and it is unknown how performance varies for specific topics or focused searches. Clinicians, researchers, and users should be aware when expected performance is not achieved for specific topics. The present work analyzes the behavior of these methods for a variety of topics. *Impact factor*, clinical query filters, and PageRank vary widely across different topics while a topic-specific *impact factor* and machine learning-based filter models are more stable. The results demonstrate that a method may perform excellently on average but struggle when used on a number of narrower ! topics. Topic-adjusted metrics and other topic robust methods have an advantage in such situations. Users of traditional topic-sensitive metrics should be aware of their limitations. (C) 2011 Elsevier Inc.

One of the tools most widely used to evaluate and compare journals is the Thomson Reuters *Impact Factor* In Poland a specific value of a scientist's *Impact Factor* is required for academic promotion. Ginekologia Polska was placed on the Master Journal List in 2008 in the result of changes introduced in 2007 by the new Chief Editor, prof. Marek Spaczynski. In 2010, first time in its history the journal was listed in the Journal Citation Reports with the *Impact Factor* 0.367. The analysis of Ginekologia Polska contemporary value, as well as of prospects for its development was conducted on the basis of the Journal Citation Reports. In the light of the JCR data, Ginekologia Polska is a highly regarded title compared to other Polish journals. Its value and importance is gradually growing.

We hypothesized that there were differences among the anesthesiology journals in both the total number of self-citations and the proportion of self-citations to the total number of references in each manuscript for the years 2005 and 2010. METHODS: We conducted a review of a sample of manuscripts from 2005 and 2010 to examine the number and rate of self-citations. As a secondary analysis, we reviewed *impact factor* (IF), rate of self-referencing, and contribution of self-citations to IF in the population of manuscripts published in 8 anesthesia journals between 2000 and 2009 using the ISI Journal Citation Reports. RESULTS: The number (P < 0.0001) and rate (P < 0.0001) of self-citations among the different journals were significantly different in 2005, with similar results for 2010 in the number (P < 0.0001) and rate (P = 0.0002) of self-citations. The mean range of number of self-citations ranged from 0.45 (95% confidence interval [CI], 0.06 to 0.84) to 3.95 (95% CI, 2.2 to 5.7) in 2005 and from 0.25 (95% CI, -0.05 to 0.55) to 4.5 (95% CI, 2.2 to 6.9) in 2010. On a per-journal basis, no difference in the number of self-citations was noted between 2005 and 2010. Analysis of the ISI Journal Citation Reports from 2000 to 2009 suggested a general decline in the contribution of self-cites to the IF over time for the aggregate journals (Spearman correlation coefficient (Rs) -0.25 (95% CI, -0.45 to -0.03), P = 0.02), with the exception of the journal in question (Rs = 0.59 (95% CI, -0.1 to 0.88), P = 0.05). Positive correlations were found between self-cited rate and IF (Rs 0.52, 95% CI, 0.3! 4 to 0.66, P < 0.0001), percentage of self-cites to years used in IF calculation and IF (Rs 0.41, 95% CI, 0.21 to 0.58, P < 0.0001), and delta-IF and IF (Rs 0.89, 95% CI, 0.84 to 0.93, P < 0.0001). CONCLUSION: Although the number and rate of self-citations differed among anesthesia journals, the contribution of self-citation to IF has declined over time for most anesthesia journals. These results suggest periodic reassessment may be important to ensure that the publication process remains transparent and impartial to bias.

Despite a 61% reduction in citation counts from the peak year (1989: Year 4) to the final year (2010: Year 25), many of these articles were still being cited 25 years after they had been published. When the sample was divided into four categories of impact using the total citation counts for each article-low impact (0-24 citations), moderate impact (25-99 citations), high impact (100-249 citations), and very high impact (250-1763 citations)-the yearly citation counts of low to high-impact articles peaked earlier and displayed a steeper decline than the yearly citation counts of very high-impact articles. Using 5 or more citations a years, 10 or more citations a year, and 20 or more citations a year as markers of moderate-impact, high-impact, and very high-impact articles, respectively, and using the most cited articles in a jou! rnal during the first 5 years of the follow-up period as indicators of high impact and very high impact showed promise of predicting impact over the entire 25-year period.

We also look for variations in index coverage by journal subject, journal size, publisher type, publisher size, date of first OA issue, region of publication, language of publication, publication fee, and citation *impact factor*. Two databases, Biological Abstracts and PubMed, provide very good coverage of the OA journal literature, indexing 60 to 63% of all OA articles in their disciplines. Five databases provide moderately good coverage (22-41%), and four provide relatively poor coverage (0-12%). OA articles in biology journals, English-only journals, high-impact journals, and journals that charge publication fees of $1,000 or more are especially likely to be indexed. Conversely, articles from OA publishers in Africa, Asia, or Central/South America are especially unlikely to ! be indexed. Four of the 11 databases index commercially published articles at a substantially higher rate than articles published by universities, scholarly societies, nonprofit publishers, or governments. Finally, three databases-EBSCO Academic Search Complete, Pro-Quest Research Library, and Wilson OmniFile-provide less comprehensive coverage of OA articles than of articles in comparable subscription journals.

Source: OSTEOARTHRITIS AND CARTILAGE 19 (7): 858-863 10.1016/j.joca.2011.02.006 JUL 2011 Language: English Document Type: Article Author Keywords: Prosthesis; Randomized controlled trial; Meta-analysis; Register; Citation KeyWords Plus: RANDOMIZED CONTROLLED-TRIALS; TOTAL HIP-REPLACEMENT; ARTHROPLASTY REGISTER; SURGICAL INNOVATION; EXTERNAL VALIDITY; SURGERY Abstract: Objective: National arthroplasty registers are often cited as examples of a non-randomized design that have made an essential contribution to advances in assessing arthroplasty procedures. We aimed to compare national registers to randomized controlled trials (RCTs) and meta-analyses in the field of arthroplasty in terms of scientific production and impact. Method: We systematically searched Medline via PubMed and the registers' websites to select all articles from national registers, RCTs and meta-analyses assessing hip and knee arthroplasty. The scientific production and impact were evaluated by number of publications, number of citations (total and the 3-year citation counts), and information on the 2008 journal *impact factor* (IF), for each design and identified articles. We also contacted representatives of all the selected registers to determine the availability of the data for external research projects. Results: We retrieved information on 13 active national hip or knee arthroplasty registers; for 9, data were available for research projects under specific conditions. Overall, 190 publications in peer-reviewed journals resulted from national arthroplasty registers, 476 from RCTs, and 40 from meta-analyses. We found 4,112 citations for national register reports, 7,328 for RCT reports and 552 for meta-analysis reports. The median [interquartile [IQR] range] number of citations for register, RCT and meta-analysis reports in the 3-year period after publication was 3.5 [1.0-6.0], 2.0 [1.0-6.0], and 2.5 [0.5-7.5], respectively. Conclusion: Publications from national registers may have the highest impact among the 3 designs in terms of median citation counts, but data from RCTs remain the most productive evidence in the arthroplasty field. Because of the number of patients recruited by registers, the quality of data collected, and the potential availability of data, scientific production and impact from national registers should be improved.

Many OpenURL link resolvers offer a citation finder service which allows the end user to search for specific known items at the article level. This paper studies the usability of the "citation linker" search from Ex Libris' SFX (R). Twenty-one volunteers tested finding known journal articles using both a standard A-to-Z list and SFX' citation linker search. The researchers compare results from the two search interfaces, document the problems found, recommend which interface makes the best default search interface, and suggest improvements to the citation linker interface.

Empirical analysis is via an expert survey and Co-word analysis using the United States Patent and Trademark Office database to obtain useful data. Analytical results demonstrate that the S-curves is a highly effective means of quantifying how technology forecasting of cumulative publication patent number. Analytical results also indicate that technologies for generating and storing hydrogen have not yet reached technological maturity; thus, additional R&D funding is needed to accelerate the development of hydrogen technology. Conversely, fuel cell technologies have reached technological maturity, and related patent strategies include freedom to operate, licensing, and niche inventions. The proposed model can be applied to all high-technology cases, and particularly to new clean technologies. The study concludes by outlining the limitations of the proposed model and directions for further research. Copyright (C) 2011, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.

The aim of this paper was to investigate New Zealand's (NZ) TC research capacity along with the quantity and quality of publications, following two government initiatives aimed, in part, at improving the quantity and quality of NZ TC research. Method: Scopus was searched for articles with at least one NZ author and where the topic was of primary relevance to TC. Publications were organized into two time periods, following the government initiatives, 1993-2003 and 2004-2009. We analyzed the number of publications, publication journals, type of publications, impact (using the impact factor), and authorship. Results: There has been an increase in number and impact of publications and number of authors. The number of publications has increased from an average of 14 (1994-2003) to 38 per year (2004-2009). The number of journals published increased from 64 to 86. The impact during 2004-2009 was almost three fold than in 1993-2003. The number of authors increased from 212 to 345, and the number of authors who had at least one first-authored publication increased from 80 to 124. Conclusions: These results show an encouraging trend in NZ TC research, with an increase in research productivity, quality, and in research capacity. It is possible that government-initiated and -funded infrastructural support contributed to increasing needed TC research, which supports the worth of such initiatives.

This error probably came from a misinterpretation of the Czech language, in which the real author's name - Hlava - can mean 'Title'. It was finally recognized, which was not the case for the author of the sentence: I have no need of hope to take action, nor of success to persevere: it is still regularly attributed in France to William I, Prince of Orange, called the Silent. It is a mistake, and no serious reference certifies that an historical figure would have pronounced this sentence. It was written by the historian Mignet in 1841, to describe the character of William III, Prince of Orange and King of England. It was then used in 1875 by Jules Verne, to describe a character in The Mysterious Island. (C) 2011 Published by Elsevier Masson SAS.

The disciplines of references and co-authors from five information science journals were analysed. Furthermore, Brillouin's Index was adopted to measure the degree of interdisciplinarity. The study revealed that information science researchers have cited the publications of library and information science (LIS) most frequently. The co-authors of information science articles are also primarily from the discipline of LIS, but the percentage of references to LIS is much higher. This indicates that information science researchers mainly rely on publications in LIS, and they often produce scientific papers with researchers from LIS. The discipline rankings generated by direct citation and co-authorship show a significant consistency via Spearman's correlation coefficient test. The interdisciplinary degree of information science has displayed growth. In particular, the degree of interdisciplinarity for co-authors has grown.

This indicator combines production and impact, and eliminates biases caused by the tails of the citations distribution. However, this indicator has limitations in discriminating between researchers with different publication habits, penalising in h-index based evaluations those who follow a more selective publication strategy and publish a relatively low number of documents that are frequently cited. This paper presents an empirical application of environment indicators, an addition to the h-index that considers the intermediate zone of the citations distribution.

In this paper, an intelligent method is proposed to identify manipulative self-citation behaviour in journals using pattern recognition. Data on IFs, age distributions of total citations, and numbers of self-citations were collected for 18 journals from 1998 to 2007 in Journal Citation Reports (JCR); these journals include known manipulated journals. The feature variables of the citation distribution functions of the known manipulated journals were extracted using the k- nearest neighbour classifier, and a feature attribute space was established for pattern recognition. The MATLAB software was used to process, train, and test the data and to develop a suitable matrix model which can provide an original model for identifying other manipulated journals. To verify the validity and reliability of this method, the authors randomly collected citation distribution data from several journals in JCR, analysed the results of the verification, and proved the effectiveness of pattern recognition in this context.

Most previous studies solved the problem with either a subjective approach, based on expert survey metrics, or an objective approach, based on citation-based metrics. Since both have their own advantages and disadvantages, and since they are usually complementary, this work proposes a brand new approach that integrates the two. In this work, we propose the Evolutionary PageRank algorithm, which first uses the PageRank algorithm to evaluate journal prestige and then uses the Multi-Objective Particle Swarm Optimization to balance citation analysis and expert opinion. Experiments evaluating ranking quality were carried out with citation records and experts' surveys to show the effectiveness of the proposed method. The results indicate that the proposed method can improve PageRank journal ranking results.

In contrast, exponential random graph models used in this article demonstrate that the uncertainty and centralized influence typical of an emerging area of research leads to the creation of a densely interconnecting core that acts to cohere the network. Moreover, eclecticism and innovativeness, also characteristic of a developing area, lead to a diffusely connected structure.

Source: JOURNAL OF MEDICAL BIOCHEMISTRY Volume: 30 Issue: 2 Pages: 79-92 DOI: 10.2478/v10011-011-0003-9 Published: 2011 Abstract: Modern Academic Science is largely based on the formulation of hypotheses that are then confirmed through observations and experiments. There is little scope for curiosity that played an important role in early Science. Results carrying negative implications are not easy to publish, and hypotheses have a tendency to take on the mantra of religious beliefs. Academic Science is facing on many fronts pressures that hardly existed in the past. Financial rewards apart from salary can be very high, in the form of fees for consultants, expert legal witnesses, patent development and even the establishment of private companies. Commercial funding forms a significant percentage of the Total Research Budgets in Science and Medicine, but this often leads to loss of control over research protocols and freedom to communicate the results. Media attention confers fame and prestige that is assiduously sought out by some individuals scientists, often supported by University resources, and Press Conferences prior to or synchronous with actual publication. Scientists have long been employed full-time by Government Departments, but research contracts are being increasingly offered by the latter to academic staff on a part-time basis. These pressures and opportunities, together with the priority given to research by most University Tenure and Promotion Committees, are tending to diminish the appetite of scientists for other important responsibilities such as teaching and administration. In a few decades, University scientists have moved from the "Ivory Tower" to the High Street, and many are serving more than one master. The above scenario may bring increased remuneration and the pursuit of research that would be too expensive without these external sources, but adverse consequences have also occurred. They may lead to the complicity of scientists, through no fault of their own, in the introduction of drugs and supplements that: a) fail to deliver the benefits claimed; b) increase the risk of some unrelated illness; c) possess dangerous side effects not known or reported at the time of introduction. Examples include hormone replacement therapy and antioxidant vitamins (A and E) to protect against Coronary Heart Disease; dietary fibre to prevent colon cancer; and arguably calcium supplements to treat osteoporosis. On occasions, academic scientists have served as fronts for the publication by the manufacturers of falsified reports minimizing the risk of serious drug side-effects to ensure Regulatory Approval, as occurred with Vioxx in the treatment of arthritis, and Seroquel for schizophrenia and bipolar depression. Individual fraud or misconduct is more frequent than suspected, because most incidents are without major impact and are suppressed by Universities and Funding Agencies. Major scandals are rare, but may have serious repercussions for the general public and bring science into disrepute. Recent examples include: the Cold Fusion controversy (Low Energy Nuclear Reaction); the linkage by Andrew Wakefield of autism with Rubella vaccination; the infamous creation of stem cells by somatic cell nuclear transfer falsely reported by Hwang Woo-Suk. Fraud by commercial companies is subject to the full force of the law, but Science is treated as a self-regulating profession, and as such the punishments handed out are relatively trivial. In essence, Science prior to 1950, except in North America, proceeded along a highway that segregated the traffic into Commercial, Government and Academic streams, and passed through inspiring landscapes and green pastures. It lter came to a crossroads from which the alternative road led to the Marketplace, and on which segregation into the above three streams was not enforced. It has now become the main thoroughfare for Science world-wide, but there are reasons to believe that this has increased the incidence of dangerous driving and traffic accidents in the form of conflicts of interest, unethical behaviour, misconduct and even fraud. It may be too late to return to the crossroads and continue along the original highway, but there could be considerable merit in restoring the original segregation between the three streams of Science and in developing, as well as enforcing, a stricter code of behaviour, for which some elements are proposed.

The United Kingdom's General Practice Research Database (GPRD) is one of the few electronic health databases publicly available to academic researchers. This study analyzed studies that used GPRD to demonstrate the scientific production and academic impact by a single public health database. Methodology and Findings: A total of 749 studies published between 1995 and 2009 with 'General Practice Research Database' as their topics, defined as GPRD studies, were extracted from Web of Science. By the end of 2009, the GPRD had attracted 1251 authors from 22 countries and been used extensively in 749 studies published in 193 journals across 58 study fields. Each GPRD study was cited 2.7 times by successive studies. Moreover, the total number of GPRD studies increased rapidly, and it is expected to reach 1500 by 2015, twice the number accumulated till the end of 2009. Since 17 of the most prolific authors (1.4% of all authors) contributed nearly half (47.9%) of GPRD studies, success in conducting GPRD studies may accumulate. The GPRD was used mainly in, but not limited to, the three study fields of "Pharmacology and Pharmacy", "General and Internal Medicine', and "Public, Environmental and Occupational Health". The UK and United States were the two most active regions of GPRD studies. One-third of GRPD studies were internationally co-authored. Conclusions: A public electronic health database such as the GPRD will promote scientific production in many ways. Data owners of electronic health databases at a national level should consider how to reduce access barriers and to make data more available for research.

Source: PLOS ONE Volume: 6 Issue: 6 Article Number: e20885 DOI: 10.1371/journal.pone.0020885 Published: JUN 16 2011 Abstract: Background: Author self-citation contributes to the overall citation count of an article and the impact factor of the journal in which it appears. Little is known, however, about the extent of self-citation in the general clinical medicine literature. The objective of this study was to determine the extent and temporal pattern of author self-citation and the article characteristics associated with author self-citation. Methodology/Principal Findings: We performed a retrospective cohort study of articles published in three high impact general medical journals (JAMA, Lancet, and New England Journal of Medicine) between October 1, 1999 and March 31, 2000. We retrieved the number and percentage of author self-citations received by the article since publication, as of June 2008, from the Scopus citation database. Several article characteristics were extracted by two blinded, independent reviewers for each article in the cohort and analyzed in multivariable linear regression analyses. Since publication, author self-citations accounted for 6.5% (95% confidence interval 6.3-6.7%) of all citations received by the 328 articles in our sample. Self-citation peaked in 2002, declining annually thereafter. Studies with more authors, in cardiovascular medicine or infectious disease, and with smaller sample size were associated with more author self-citations and higher percentage of author self-citation (all p <= 0.01). Conclusions/Significance: Approximately 1 in 15 citations of articles in high- profile general medicine journals are author self-citations. Self-citation peaks within about 2 years of publication and disproportionately affects impact factor. Studies most vulnerable to this effect are those with more authors, small sample size, and in cardiovascular medicine or infectious disease.

This raises two related questions: (1) Are firms increasingly conducting scientific basic research? (2) Is being at the scientific forefront helping firms to be closer to the technological frontier? This paper examines scientific output, as measured by numbers of papers, and technological output, as measured by patents granted to all Canadian firms, during the 1980 to 2005 period. Though the number of firms publishing papers and obtaining patents is increasing, scientific research and patenting by Canadian firms are at near 'homeopathic' levels. Firms that both publish papers and obtain patents (1) perform research that is more basic than firms that only publish scientific papers; (2) publish in more highly cited journals than firms that only perform scientific research; (3) publish papers that are more highly cited; and 4) hold patents that are more frequently cited.

Design/methodology/approach - This paper searches citation of the Scopus and Web of Science databases. Findings - Both publication and citation rates are low, although this is at least in part due to some Malaysian universities having only a teaching function. More of the departments' publications were identified in Scopus than in Web of Science, but both databases were needed for comprehensive coverage. Statistically significant relationships were observed between the departments' publication and citation counts and the rankings of the departments' parent universities in two evaluations of the research performance of Malaysian universities. Originality/value - This is the first comparison of bibliometric and peer-review data for Malaysia, and, more generally, for a country with a newly developed higher education system.

The citation pages of their research papers revealed that the students used more books, more types of sources, and more overall sources when a librarian provided instruction. When these results were compared to those produced by students in upper-level classes (all of whom received instruction), it was discovered that, as the class level increased, the number of citations and the percentage of scholarly citations generally increased and there was a high preference for books from all disciplines, especially history.

There is great variation in the size of OA journals; the largest publishes more than 2,700 articles per year, but half publish 25 or fewer. While just 29 percent of OA journals charge publication fees, those journals represent 50 percent of the articles in our study. OA journals in the fields of biology and medicine are larger than the others, more likely to charge fees, and more likely to have a high citation impact. Overall, the OA journal landscape is greatly influenced by a few key publishers and journals.

In this paper we present an adapted leaders method combined with a compatible adapted agglomerative hierarchical method that are based on relative error measure between a unit and the corresponding cluster representative-leader. The proposed approach is illustrated on citation distributions derived from the data set of US patents from 1980 to 1999. These new methods were developed because clustering of units, described with distributions, with classical k-means method reveals patterns with single high peaks which correspond to a single year. These patterns prevail over other distribution shapes also present in the data. Compared with centers in k-means method, clusters' representatives obtained with the proposed new methods better detect typical distribution shapes of units. The obtained main cluster types for different sets of units show three main patterns: patents with early or late peak of importance to the community, and patents where the importance is slowly increasing throughout the time period.

METHODS The PubMed database was searched for all articles published from 1995 to 2010 that originated from Turkish EM departments. RESULTS A total of 514 articles were included. Of all articles, 77% (n=396) were published in the last five years. Publications were detected to increase at a rate of 6.2 articles per year. 58.7% (n=302) of the articles were published in non-EM journals. Advances in Therapy in the non-EM group, with 27 articles, and the Turkish Journal of Trauma & Emergency Surgery in the EM group, with 48 articles, were the preferred journals. The most popular subjects were toxicology, at 26% (n=134), followed by trauma, at 16% (n=86). 7.7% (n=40) of all articles were animal studies and 6% (n=31) were randomized controlled trials. CONCLUSION Significant publication growth was detected related with the development of EM in Turkey. The preference for non-EM journals, toxicology as the most popular subject and the effect of university hospitals were the interesting results of this study. The low number of multicenter, randomized controlled trials and of published articles in high impact factor journals have led us to consider the importance of publication quality, which requires additional effort.

AUG 2011. p.898-904 WILEY-BLACKWELL, MALDEN S KEYWORDS+: IMPACT FACTOR; SCIENCE; TRENDS ABSTRACT: Objectives: Emergency medicine (EM) is a young but rapidly growing field. An evaluation of academic performance and the growing impact of EM journals would help to elucidate the increase in the number of EM scientific studies. The authors used the Journal Citation Reports (JCR) database to investigate the scientific achievements of EM journals in the past 10 years. Methods: This was a literature review study. All data were collected from the JCR database. Journals listed in the EM category from 2000 to 2009 were included. Eleven categories that were considered most closely related to EM by a consensus of the authors were chosen for comparison, including cardiac and cardiovascular systems, clinical neurology, critical care medicine, gastroenterology and hepatology, infectious diseases, general and internal medicine, pediatrics, respiratory system, surgery, toxicology, and urology and nephrology. Data on journals in the EM category were collected, including journal title, language, journal country or territory, impact factor for each year, total number of EM journals for each year, and the EM category aggregate impact factor (available from 2003 to 2009). The variables in the comparison group included the number of journals in each of the 11 clinical medicine categories from 2000 to 2009 and the aggregate impact factors for 2003 to 2009. The category aggregate impact factor and journal impact factor were adopted as representative of category and journal academic performance. Linear regression was used to assess the trend of aggregate impact factor and journal impact factor. The slope (beta) of the linear regression was used to represent the evolution of performance. The relationship between the 2000 EM journal impact factor and the impact factor trend of EM journals between 2000 and 2009 was measured by Pearson correlation coefficient to evaluate the evolution difference between journals with different initial impact factors. Results: In 2000, all 12 EM journals were published in the United States or Europe, and the language of all was English. In 2009, 10% (2/19) of the journals originated from outside North America and Europe, and 16% (3/19) were non-English-language journals. The number of EM journals increased 58% from 2000 to 2009, twice the increase in the total number of JCR-listed journals, and rank first in the rate of journal number increase among categories of clinical medicine. The impact factor of all EM journals showed an increasingly positive trend since 2000. The impact factor increased faster for high impact factor EM journals than for low- impact-factor EM journals. Conclusions: An increasing number of international EM journals have appeared over the past 10 years. Every EM journal exhibited a positive impact factor trend, but the gap between EM journals' impact factors has widened in the past 10 years.

Bibliometrics provide surrogate measures of the quality and quantity of research undertaken by departments and individuals. Previous reports have suggested that academic anaesthesia research in the UK is in decline. We wished to provide a comprehensive description of current and historical published output of UK anaesthesia researchers. Methods. Bibliometric indices (Web of Science (R)) were calculated for anaesthesia researchers in the UK for the whole period covered by the database, and for 2004-8. A parallel search was made using the Scholarometer (TM) tool, which parses output from Google Scholar (TM). Calculated indices included total number of publications; total number of citations; citations per paper; h-index; g-index; and modified impact index. Results. One hundred and four individuals and 23 academic departments were identified. Median values (inter-quartile range) for the indices were: total papers 57 (24-95) (individuals for the whole period), 11 (6- 20) (individuals 2004-8), 50 (30-70) (departments 2004-8); total number of citations 571 (175-1328), 93 (38-207), 383 (239-845); h-index 13 (8- 20), 6 (3-8), 11 (9-14). Four departments were ranked in the top 5 for all indices. Conclusions. The general distribution of bibliometric data is similar to that seen in other specialities in Europe and North America. Four departments contribute to more than 50% of published anaesthesia research output in this data set. These data provide useful comparative tools for individuals, departments, and national bodies.

We conducted a bibliometric analysis of h-index in editorial board members and tested the hypothesis that editorial board members of anaesthesia journals with higher impact factors (IFs) have higher h-indices. Methods. Ten of 19 journals with 2009 IF>1 were randomly chosen from Journal Citation Reports (R). Board members were identified using each journal's website. Publications, citations, citations per publication, and h-index for each member were obtained using Scopus (R). Results. Four hundred and twenty-three individuals filled 481 anaesthesia editorial board positions. The median h-index of all editorial board members was 14. Board members published 75 papers (median) with 1006 citations and 13 citations per publication. Members serving on journals with IF greater than median had significantly (P<0.05; Wilcoxon's rank- sum test) greater median h-index, citations, and citations per publication than those at journals with IF less than median. A significant correlation between the median h-index of a journal's editorial board members and its IF (h-index 3.01xIF+6.85; r(2)=0.452; P=0.033) was observed for the 10 journals examined. Board members of subspeciality-specific journals had bibliometric indices that were less than those at general journals. The h-index was greater in individuals serving more than one journal. European editorial board members had higher h-index values than their American colleagues. Conclusions. The results suggest that editorial board members of anaesthesia journals with higher IFs have higher h-indices.

OCT 2011. p.483-502 SPRINGER, DORDRECHT KEYWORDS: Doctoral graduate; Research performance; Individual factor; Advisor; Learning performance KEYWORDS+: RESEARCH PRODUCTIVITY; PUBLICATION PRODUCTIVITY; ACADEMIC SCIENTISTS; HIGHER-EDUCATION; JOURNALS; QUALITY; DEPARTMENTS; ORIGIN ABSTRACT: Doctoral graduate research performance (DRP) is recognized as one of the most critical indices for evaluation of the success of doctoral education. Doctoral graduates with high research performance directly reflect a higher ability in academic research and academic achievement. Consequently, identifying which factors influence DRP is potentially of great value. This topic is also challenging because of difficulties in identifying the impact factors on research performance and the feasibility of the relative data collection. This paper first examines the relationships between the indicators and DRP. After a review of previous literature, the focus is on the doctoral graduates' individual factors, advisor factors and learning performance. Data is collected from graduated doctors from the Science Schools of University of Science and Technology of China (USTC). Contrary to expectations, our findings indicate that, based on the Chinese context, learning performance does not appear to be strongly associated with research performance. Individual factors (status of academic origin) do have significant effect on DRP. The advisor factors (including academic status, academic experience and allocation of energy) show a relatively strong association with DRP, in terms of both the number of publications and the impact factor of Science Citation Index (SCI) cited journals.

The first viewpoint outlines the importance of promoting research collaboration among ASEAN researchers and their international peers in increasing the visibility and impact of ASEAN research. The second viewpoint examines the ASEAN research characteristics, the challenges and existing best practices of its journal publishing landscape, the potential role of non-ASEAN international journals in improving the profile of ASEAN research and explores the needs and benefits of establishing an ASEAN Integrated Journal Publishing Network (IJPN). It is through these combined approaches, we believe, that effective policy change, the standardisation of publishing structure, procedures, and systems to drive journal development, improvement of journal quality, and establishment of a consistent framework for measuring researcher performance will result. This article also includes a proposal for the IJPN structure and implementation plan, and highlights the key benefits of taking a collaborative approach to achieving this common goal.

JUL 2011. p.27-37 ROYAL SOC MEDICINE PRESS LTD, LONDON SEARCH TERM(S): BIBLIOMETR* item_title ABSTRACT: Objective: Europe's health care decision-makers are facing an increasingly complex and rapidly changing landscape. It is crucial that health care problems are addressed with evidence-informed policy and that evidence finding is aimed at those topics most urgent on policy agendas. Research on health systems addresses the macro-level of health care delivery and aims at generating evidence for policy-making. Our aim was to assess the field of health systems research in Europe, primarily based on an analysis of the published literature. Methods: Starting from current definitions of health systems, during 2004- 09 we identified four thematic areas for research and defined keywords to construct a sensitive literature search limited to European research. Results: The database search resulted in 26,945 hits between 2004-09. Until 2008, the annual number of publications on health systems research increased at an average rate of 5.2%. Most (88%) were in English. The largest producer of research on health systems has been the UK (nearly 10,000 in six years; 37% of the total for Europe), which is also the country most frequently the object of research. In contrast, seven countries had produced no publications. There were modest correlations between a country's research production and its gross domestic product (r = 0.62) but less so with its population size (0.33). The most frequent keywords were 'patients' (49% of all references), 'patient satisfaction' (27%), 'organization and administration' (23%), 'education' (19%) and 'attitude of health personnel' (13%). Closer inspection of a sub-sample of 1000 abstracts revealed that only 24% met our definition of 'health systems research' rather than other fields of health services research. Conclusion: There is a wide-spread need to develop health systems research capacity, in particular in eastern European countries, and to address the effects of health care reform, particularly the effects of privatization and commercialization of health services.

(Article, English) AUTHOR: Tourish, D SOURCE: LEADERSHIP 7 (3). AUG 2011. p.367-381 SAGE PUBLICATIONS INC, THOUSAND OAKS SEARCH TERM(S): JOURNAL item_title KEYWORDS: journal rankings; academic freedom; performativity; research assessment KEYWORDS+: CRITICAL MANAGEMENT; QUALITY; FIELD; PROGRESS; SENSE ABSTRACT: Pressure on academics to publish articles in 'top' journals continues to grow. In tandem, we have seen a proliferation of journal rankings, claiming to provide a guide to the quality of journals. As editors become more preoccupied by the ranking of 'their' journal, they exercise performative power over authors, by setting standards for publication that exclude many while compelling those that are published to adapt to the styles, priorities and imperatives of editors. One result has been a ceaseless quest for novelty, manifest in an insistence that each paper must make a 'distinctive' theoretical contribution. I argue that this is producing an environment in which scholarship is increasingly mechanized and industrialized, while rendering its outputs more arcane and inaccessible to non-specialists. It also means that the academy is becoming ever more complicit in its own subordination to performative processes that it frequently criticizes when observing them in the outside, 'real' world of management practice. We are therefore seeing more barriers to entry for both authors and new journals - unless both conform to norms that bear an orthodox but often sterile imprint. I consider the implications of these issues for emergent journals such as Leadership, and for academic freedom, and suggest how those interested in scholarly inquiry in general and the fate of this journal in particular should respond.

We performed a systematic review to identify the indicators that have been used to measure healthcare research performance. We evaluated their feasibility, validity, reliability and acceptability; and finally assessed the utility of these indicators in terms of measuring performance in individuals, specialties, institutions and countries. Design A systematic review was performed by searching EMBASE, PsycINFO, Ovid MEDLINE and Cochrane Library databases between 1950 and September 2010. Setting Studies of healthcare research were appraised. Healthcare was defined as the prevention, treatment and management of illness and the preservation of mental and physical wellbeing through the services offered by the medical and allied health professions. Participants All original studies that evaluated research performance indicators in healthcare were included. Main outcome measures Healthcare research indicators, data sources, study characteristics, results and limitations for each study were studied. Results The most common research performance indicators identified in 50 studies were: number of publications (n = 38), number of citations (n = 27), Impact Factor (n = 15), research funding (n = 10), degree of co-authorship (n = 9), and h index (n = 5). There was limited investigation of feasibility, validity, reliability and acceptability, although the utility of these indicators was adequately described. Conclusion Currently, there is only limited evidence to assess the value of healthcare research performance indicators. Further studies are required to define the application of these indicators through a balanced approach for quality and innovation. The ultimate aim of utilizing healthcare research indicators is to create a culture of measuring research performance to support the translation of research into greater societal and economic impact.

The h-I can be estimated from several sources, but no "gold-standard" approach has yet been established. The aim was to analyze the discordance rates in Hepatology between five h-I assessments from five databases: Scholar, Scopus, Web of Science (WoS), ScholarL restricted to "liver", and a specialty h-I HepaTop. Methods: The reference for the main endpoint was "h-I 50", the median of included authors. Applicability and accuracy were assessed among 158 authors identified in the top 100 of the most cited "clinical" Hepatologists by two independent sources. The accuracy assessment used the area under the receiver operating characteristics curves (AUROCs) standardized or not according to spectrum effect, and the Pearson (PCC), and intraclass (ICC) coefficients of correlation. Results: Performances varied significantly according to h-I (P < 0.001). Applicability was 80% for h-HepaTop and 100% for other h-I. AUROCs ranged from 0.55 (h-Scholar) to 0.88 (h-HepaTop). The h-I were highly inter- correlated but without perfect concordance: ICCs ranged from 0.01 (h-WoS versus h-Scholar) to 0.53 (h-WoS versus h-Scopus; P < 0.0001). There were no differences between the AUROCs for h-Scopus, h-WoS and h-HepaTop, with lower accuracy for h-Scholar. The h-WoS AUROC adjusted for risk factors, scientific age and homonymy, increased in combination with h-HepaTop from 0.83 to 0.94 P = 0.005. Conclusions: The h-I should be carefully checked before any hepatologist's evaluation. Three factors were associated with applicability and accuracy: the data source, the risk of homonyms, and scientific age. A unique "global" identification number is warranted.

The point was forcefully supported by Richard Ernst in a post-face entitled 'The Follies of Citation Indices and Academic Ranking Lists.([3,4]) We received a surprising number of passionate responses, such as 'It's written out of my heart' (TH); 'Je soutiens cette entreprise courageuse de tout coeur' (VT); 'Impact Faktoren sind ein Marktinstrument gewisser Verlage (FS); 'II y a un combat a mener' (SB). Some thoughtful responses have been incorporated into this Essay, albeit in attenuated form. We suggest that the 'fertility' of individual scientists be appreciated in terms of kinship rather than through personalized indices.

How useful are bibliometric indices for the evaluation of "scientific quality" or "scientific productivity"? Author(s): Halbach, OVU (Halbach, Oliver von Bohlen Und) Source: ANNALS OF ANATOMY-ANATOMISCHER ANZEIGER Volume: 193 Issue: 3 Pages: 191-196 DOI: 10.1016/j.aanat.2011.03.011 Published: 2011 Abstract: How to pre-select the most promising candidates for an open position out of several applications? One of the possibilities is to check the personal bibliometric indices of these candidates by looking into appropriate databases. In these databases the number of publications, the total number of citations, the average number of citations per paper and the h-index are easy to find. Thus, it is easy to use these parameters for a pre-election. First, the particular values for the several bibliometric indicators could be retrieved for scientists working in the field of Anatomy & Cell Biology. Next, an analysis of how useful and reliable these bibliometric indicators are is performed. Most of the indicators strongly depend on the seniority of a researcher. Thus, these indicators favour older scientists over younger ones. Based on that, these indicators are not well-suited to identify young and promising scientists. Therefore, it is proposed that indicators, which correct for the time a scientists spends working in the field, may be better suited for such a pre-election, such as the hy index (also known as m-index) or the Py index. In this context, it should be emphasized that these indicators may be useful for pre-selection. All available indicators are based on data obtained from the past achievements of the scientists and may not predict their future achievements. However, despite the availability of these indicators, the best method to gain an impression of the quality is currently still the old-fashioned method of reading the papers. (C) 2011 Elsevier GmbH.

The GIScience research priorities identified by the University Consortium of Geographic Information Science (UCGIS) were used as guidelines to examine the 985 research articles published in six well-recognized academic journals. Latent Semantic Analysis (LSA) was employed to investigate the association among the different GIScience research themes. The spatial and temporal patterns of the association between the publications and the different GIScience themes were examined to show the development of GIScience research during the study period. Furthermore, correlation analyses between the publications were conducted following the LSA results to reveal GIScience research networks, including the networks of the published articles and those formed by the research places. In this article, we applied an approach that was developed within information science to depict what GIS research activities were conducted when and where and how they connect to each other through sharing common research themes. The related findings pave the way for future efforts to describe the paradigm of GIScience as well as the pattern of GIScience research.

Therefore the use of medians and quantiles should be preferred. The background of this myth is quite obvious. The Gaussian normal distribution, being one of the most important families of continuous probability distributions, arises in many areas of statistics. If a statistical sample follows a normal distribution, then the observations should be symmetrically distributed around the sample mean and the standard deviation can be used to determine a tolerance threshold for individual observations. However, this is obviously not the case in bibliometrics. Most bibliometric distributions are far from being symmetric and discrete. Publication-activity and citation-impact distributions are often extremely skewed, the majority of the observations are below the sample mean and the rest of the sample elements are located in the long tail of the distributions. In such cases the mean value and the standard deviation seem to be completely useless. Therefore the application of classical tools of moment-based statistics seems not to be appropriate in research evaluation either. This is a misbelief. According to the central limit theorem, the distribution of the means of random samples is approximately normal for a large sample size, provided the underlying distribution of the population is in the domain of attraction of the Gaussian distribution. In other words, sample means approach a normal distribution regardless of the distribution of the population if the number of observations is large enough and the first statistical moments are finite. Consequently, means and shares of different samples drawn from the same populations can be compared with each other and the significance of the deviation can be determined. Means and shares are used as unbiased estimators of the expected value and the corresponding probabilities, respectively. Furthermore, in the case of skewed discrete distributions the mean value is superior to median. The underlying methods of application of mathematical statistics have been described, among others, by Schubert and Gl?nzel (1983), Gl?nzel and Moed (2002) and reliability-related statistics have been regularly and successfully applied to bibliometrics since. These statistical properties have severe effects on ranking issues as well. Different ranks can prove as ties because the underlying indicator values might not differ significantly (cf. Gl?nzel and Debackere 2007). The myth of the inapplicability of Gaussian statistics in a bibliometric context actually arose from a misunderstanding, namely from the assumed comparison of individual observations with a standard. However, that is not what statistics does. --David Pendlebury ________________________________ From: ASIS&T Special Interest Group on Metrics [mailto:SIGMETRICS at LISTSERV.UTK.EDU] On Behalf Of Loet Leydesdorff Sent: Tuesday, August 30, 2011 11:10 PM To: SIGMETRICS at LISTSERV.UTK.EDU Subject: [SIGMETRICS] skewed citation distributions should not be averaged A Rejoinder on Energy versus Impact Indicators Scientometrics (in press) Citation distributions are so skewed that using the mean or any other central tendency measure is ill-advised.

However, Seglen rejects the validity of the impact factor as a measure of journal worth precisely because it is the arithmetic mean of a skewed distribution. Here is what he wrote: Citational heterogeneity is thus a fundamental irreducible property of the articles in a journal (as well as of other units of science...). Very few articles will actually have a citedness close to the journal mean, thus the journal impact factor cannot be used as a representative indicator for individual journal articles. The overall journal impact can be heavily determined by a few very highly cited articles.... (p. 145) Seglen follows the traditional, historical interpretation of the arithmetic mean as representative of a type or "typical," and this requires the distribution to be normal for the arithmetic mean to be so. However, Karl Pearson proved that the normal distribution is virtually nonexistent in reality and that most distributions in reality are of the negative binomial type, because reality is not random and additive but causal and multiplicative. To approximate the law of error, you are given the transformational mantra of log + 1 (in case of zeros), and this makes the geometric mean typical. From this perspective, it would seem, Professor Leydesdorff has a better grasp of the situation, and I stand with him. He's my buddy.

The median - another measure of central tendency - is not. Whether there is such an effect of (a few) highly-cited papers can be checked by comparing the mean with the median for the citations of a publications set. If the mean is significantly higher than the median highly cited papers are effective here. Best, Lutz --------------------------------------- Dr. Dr. habil.

I noticed your example of individuals at the University of Amsterdam in your paper - and such small data sets are of course subject to many difficulties. My question arose because of the strong statement -- without qualification -- in your paper: "Citation distributions are so skewed that using the mean or any other central tendency measure is ill-advised."

This is a misbelief. According to the central limit theorem, the distribution of the means of random samples is approximately normal for a large sample size, provided the underlying distribution of the population is in the domain of attraction of the Gaussian distribution. In other words, sample means approach a normal distribution regardless of the distribution of the population if the number of observations is large enough and the first statistical moments are finite. Consequently, means and shares of different samples drawn from the same populations can be compared with each other and the significance of the deviation can be determined. Gangan Prathap's contribution is interesting in this context because using a physical metaphor, he distinguished between "energy" and "exergy". The difference (E - X), in his opinion, is "a kind of entropy"-indeed, "a kind of" because the dimensionality of energy and entropy is different. If one assumes "a kind of ideal gas," then one can compute with the mean. In evaluation research, however, we don't have so large number of observations that the constraints can be neglected. There is no reason to assume that the CLT is valid. For example, there are principles in science such as preferential attachment that operate against the assumption of a tendency to the mean. Instead of showing this each time, the approach of using percentiles does not have to make the assumption. The hundred percentiles can follow the citation curve as a continuous variable ("quantiles"). One can use non-parametric statistics (which is available for 50 or so years) instead. Instead of determining the deviation from the mean, one can test the observation against the expectation (as when using chi-square). The specification of the expectation can enrich the research design. Best wishes, Loet Means and shares are used as unbiased estimators of the expected value and the corresponding probabilities, respectively. Furthermore, in the case of skewed discrete distributions the mean value is superior to median. The underlying methods of application of mathematical statistics have been described, among others, by Schubert and Gl?nzel (1983), Gl?nzel and Moed (2002) and reliability-related statistics have been regularly and successfully applied to bibliometrics since.

Doctoral graduates with high research performance directly reflect a higher ability in academic research and academic achievement. Consequently, identifying which factors influence DRP is potentially of great value. This topic is also challenging because of difficulties in identifying the impact factors on research performance and the feasibility of the relative data collection. This paper first examines the relationships between the indicators and DRP. After a review of previous literature, the focus is on the doctoral graduates' individual factors, advisor factors and learning performance. Data is collected from graduated doctors from the Science Schools of University of Science and Technology of China (USTC). Contrary to expectations, our findings indicate that, based on the Chinese context, learning performance does not appea! r to be strongly associated with research performance. Individual factors (status of academic origin) do have significant effect on DRP. The advisor factors (including academic status, academic experience and allocation of energy) show a relatively strong association with DRP, in terms of both the number of publications and the *impact factor* of Science Citation Index (SCI) cited journals.

S.; Hudetz, J. A. Source: BRITISH JOURNAL OF ANAESTHESIA 107 (3): 357-361 10.1093/bja/aer191 SEP 2011 Author Keywords: academic anaesthesia; bibliometrics; h-index; impact factor; performance measures KeyWords Plus: SELF-CITATIONS; POWER Abstract: Background. h-index is useful for quantifying scholarly activity in medicine, but this statistic has not been extensively applied as a measure of productivity in anaesthesia. We conducted a bibliometric analysis of h-index in editorial board members and tested the hypothesis that editorial board members of anaesthesia journals with higher impact factors (IFs) have higher h-indices. Methods. Ten of 19 journals with 2009 IF>1 were randomly chosen from Journal Citation Reports (R). Board members were identified using each journal's website. Publications, citations, citations per publication, and h-index for each member were obtained using Scopus (R). Results. Four hundred and twenty-three individuals filled 481 anaesthesia editorial board positions. The median h-index of all editorial board members was 14. Board members published 75 papers (median) with 1006 citations and 13 citations per publication. Members serving on journals with IF greater than median had significantly (P<0.05; Wilcoxon's rank-sum test) greater median h-index, citations, and citations per publication than those at journals with IF less than median. A significant correlation between the median h-index of a journal's editorial board members and its IF (h-index 3.01xIF+6.85; r(2)=0.452; P=0.033) was observed for the 10 journals examined. Board members of subspeciality-specific journals had bibliometric indices that were less than those at general journals. The h-index was greater in individuals serving more than one journal. European editorial board members had higher h-index values than their American colleagues. Conclusions. The results suggest that editorial board members of anaesthesia journals with higher IFs have higher h-indices.

The present work analyses the European bio-medicolegal scientific output of the last 5.5 years (exact time window, January 1, 2005-June 1, 2010), categorising papers by nationality of the corresponding author and forensic sub-discipline in question, in order to identify the peculiarities of national sub-specialised competences and to build up international research projects. This country-based bibliometric analysis, based on the number of articles and the *impact factor* produced by each European country, also considering its economic profile (gross domestic product and per capita gross domestic product), highlights the prevailing productive role of Western and Southern Europe (Ge! rmany, Great Britain, Italy, Switzerland, Spain and France). Categorising scientific output by forensic sub-discipline and branch, significant in terms of *impact factor* are contributions from Germany (coming first in Pathology, Toxicology, Genetics, Anthropology and Biological Criminalistics), Great Britain (first in Clinical Forensic Medicine, Malpractice and Invalidity-Social Insurance), Switzerland (first in Criminology), Italy (second in Toxicology, Anthropology and Invalidity-Social Insurance), The Netherlands (third in Clinical Forensic Medicine and Medical Law and Ethics), Spain (third in Genetics, Criminalistics and Invalidity-Social Insurance) and France (third in Toxicology and Malpractice). Interestingly, several countries with low gross domestic product, such as Poland, Turkey and other Eastern European nations, show notable scientific production in specific sub-disciplines such as Pathology, Toxicology and Forensic Genetics, suggesting that fruitful internati! onal cooperation could be planned and be of interest to fundin! g source s within the European Community, also taking into account funds reserved for depressed areas undergoing development.

Method: Surgical publications relating to adult malignant diseases originating from Australia were identified from a systematic literature examination using PubMed during a 12-year period between 1998 and 2009. The origin of the article, journal *impact factor* (IF), type of research and its subspecialty discipline were recorded. Results: Over a 12-year period, 1,132 papers were published in various journals at a median annual rate of 98 papers. Four hundred eighty-five (43%) papers arose from institutions in New South Wales, 225 (20%) papers from Victoria, 150 (13%) papers from South Australia, 106 (9%) papers from Western Australia, and 77 (7%) papers from Queensland. The mean IF was 3.22 (SD = 2.5). Papers were most commonly published in journals including the ANZ Journal of Surgery (n = 237, 21%), Annals of Surgical Oncology (n = 50, 4%), British Journal of Surgery (n = 38, 3%), and Diseases of the Colon and Rectum (n = 36, 3%). The mean IF of papers published per year ranged from 2.55 to 3.87. The most number of papers were published in the fields of urological oncology (n = 103, 9%), hepatopancreaticobiliary oncology (n = 144, 13%), breast oncology (n = 174, 15%), and colorectal oncology (n = 222, 20%). Conclusion: Bibliometric findings of this review suggest that there is a growth in high scientific research publications in the field of surgical oncology in Australia, indicating an interest in this discipline. This research trend may impact on the national research strategy for clinical cancer control. J. Surg. Oncol. 2011;104:216-219. (C) 2011 Wiley-Liss, Inc.

Through electronic databases we now have enough information to compare entire research disciplines over time. We compare the complete longitudinal coauthorship networks for four research disciplines (biotechnology, mathematics, physics and sociology) for 1986-2005. We examined complete bibliographies of all researchers registered at the national Slovene Research Agency. Known hypotheses were confirmed as were three new hypotheses. There were different coauthoring cultures. However, these cultures changed over time in Slovenia. The number of coauthored publications grew much faster than solo authored productions, especially after independence in 1991 and the integration of Slovenian science into broader EU systems. Trajectories of types of coauthorship differed across the disciplines. Using blockmodeling, we show how coauthorship structures change in all disciplines. The most frequent form was a core-periphery struct! ure with multiple simple cores, a periphery and a semi-periphery. The next most frequent form had this structure but with bridging cores. Bridging cores consolidate the center of a discipline by giving it greater coherence. These consolidated structures appeared at different times in different disciplines, appearing earliest in physics and latest in biotechnology. In 2005, biotechnology had the most consolidated center followed by physics and sociology. All coauthorship networks expanded over time. By far, new recruits went into either the semi-periphery or the periphery in all fields. Two 'lab' fields, biotechnology and physics, have larger semi-peripheries than peripheries. The reverse holds for mathematics and sociology, two 'office' disciplines. Institutional affiliations and shared interests all impact the structure of collaboration in subtle ways.

An evaluation of academic performance and the growing impact of EM journals would help to elucidate the increase in the number of EM scientific studies. The authors used the Journal Citation Reports (JCR) database to investigate the scientific achievements of EM journals in the past 10 years. Methods: This was a literature review study. All data were collected from the JCR database. Journals listed in the EM category from 2000 to 2009 were included. Eleven categories that were considered most closely related to EM by a consensus of the authors were chosen for comparison, including cardiac and cardiovascular systems, clinical neurology, critical care medicine, gastroenterology and hepatology, infectious diseases, general and internal medicine, pediatrics, respiratory system, surgery, toxicology, and urology and nephrology. Data on journals in the EM category were collected, including journal title, language, journal country or territory, *impact factor* for each year, total number of EM journals for each year, and the EM category aggregate *impact factor* (available from 2003 to 2009). The variables in the comparison group included the number of journals in each of the 11 clinical medicine categories from 2000 to 2009 and the aggregate impact factors for 2003 to 2! 009. The category aggregate *impact factor* and journal *impact factor* were adopted as representative of category and journal academic performance. Linear regression was used to assess the trend of aggregate *impact factor* and journal *impact factor*. The slope (beta) of the linear regression was used to represent the evolution of performance. The relationship between the 2000 EM journal *impact factor* and the *impact factor* trend of EM journals between 2000 and 2009 was measured by Pearson correlation coefficient to evaluate the evolution difference between journals with different initial impact factors. Results: In 2000, all 12 EM journals were published in the United States or Europe, and the language of all was English. In 2009, 10% (2/19) of the journals originated from outside North America and Europe, and 16% (3/19) were non-English-language journals. The number of EM journals increased 58% from 2000 to 2009, twice the increase in the total number of JCR-listed journals, and rank first in the rate of journal number increase among categories of clinical medicine. The *impact factor* of all EM journals showed an increasingly positive trend since 2000. The *impact factor* increased faster for high *impact factor* EM journals than for low-*impact-factor* EM journals. Conclusions: An increasing number of international EM journals have appeared over the past 10 years. Every EM journal exhibited a positive *impact factor* trend, but the gap between EM journals' impact factors has widened in the past 10 years.

We introduce an alternative approach, which is based on Google's PageRank, to evaluate 31 OR/MS journals. This approach enhances the *impact factor* method by considering both citation quantity and quality. When we apply our method to OR/MS journals, the results match survey opinions and significantly outperform rankings based on impact factors. In addition, we provide an extensive discussion of other methods that have been used to assess journal quality. Compared to these methods, our method is better able to discern quality differences for journals that are perceived to be of relatively higher quality. Most importantly, we integrate our method into a Web-based journal-ranking system.

I noticed your example of individuals at the University of Amsterdam in your paper ? and such small data sets are of course subject to many difficulties.

This is a misbelief. According to the central limit theorem, the distribution of the means of random samples is approximately normal for a large sample size, provided the underlying distribution of the population is in the domain of attraction of the Gaussian distribution. In other words, sample means approach a normal distribution regardless of the distribution of the population if the number of observations is large enough and the first statistical moments are finite. Consequently, means and shares of different samples drawn from the same populations can be compared with each other and the significance of the deviation can be determined. Gangan Prathap?s contribution is interesting in this context because using a physical metaphor, he distinguished between ?energy? and ?exergy?. The difference (E ? X), in his opinion, is ?a kind of entropy??indeed, ?a kind of? because the dimensionality of energy and entropy is different. If one assumes ?a kind of ideal gas,? then one can compute with the mean. In evaluation research, however, we don?t have so large number of observations that the constraints can be neglected. There is no reason to assume that the CLT is valid. For example, there are principles in science such as preferential attachment that operate against the assumption of a tendency to the mean. Instead of showing this each time, the approach of using percentiles does not have to make the assumption. The hundred percentiles can follow the citation curve as a continuous variable (?quantiles?). One can use non-parametric statistics (which is available for 50 or so years) instead. Instead of determining the deviation from the mean, one can test the observation against the expectation (as when using chi-square). The specification of the expectation can enrich the research design. Best wishes, Loet Means and shares are used as unbiased estimators of the expected value and the corresponding probabilities, respectively. Furthermore, in the case of skewed discrete distributions the mean value is superior to median. The underlying methods of application of mathematical statistics have been described, among others, by Schubert and Gl?nzel (1983), Gl?nzel and Moed (2002) and reliability-related statistics have been regularly and successfully applied to bibliometrics since. These statistical properties have severe effects on ranking issues as well. Different ranks can prove as ties because the underlying indicator values might not differ significantly (cf. Gl?nzel and Debackere 2007). The myth of the inapplicability of Gaussian statistics in a bibliometric context actually arose from a misunderstanding, namely from the assumed comparison of individual observations with a standard. However, that is not what statistics does. --David Pendlebury _____ From: ASIS&T Special Interest Group on Metrics [mailto:SIGMETRICS at LISTSERV.UTK.EDU] On Behalf Of Loet Leydesdorff Sent: Tuesday, August 30, 2011 11:10 PM To: SIGMETRICS at LISTSERV.UTK.EDU Subject: [SIGMETRICS] skewed citation distributions should not be averaged A Rejoinder on Energy versus Impact Indicators Scientometrics (in press) Citation distributions are so skewed that using the mean or any other central tendency measure is ill-advised.

Perhaps the key point in Glanzel's paper is made with the following statements "Therefore the application of classical tools of moment-based statistics seems not to be appropriate in research evaluation either. This is a misbelief. According to the central limit theorem, the distribution of the means of random samples is approximately normal for a large sample size, provided the underlying distribution of the population is in the domain of attraction of the Gaussian distribution. In other words, sample means approach a normal distribution regardless of the distribution of the population if the number of observations is large enough and the first statistical moments are finite." The caveats are ".. approximately normal for a large sample size", ".. the underlying distribution of the population is in the domain of the Guassian distribution, and "... the first statistical moments are finite" Power law or heavy tailed distributions that have a power law with a tail exponent less than 3.0 have infinite variance which does not satisfy the central limit theorem and the use of classic moment-based statistics can be inappropriate for comparative purposes (Willinger, et al 2008). Redner (1998) and Clauset et al (2009) reported that the tail exponent for citation distributions are close to 3.0. Some of our recent investigations have examined the evolution of the tail exponent of citation distributions as a function of fixed citation window sizes. The citation distributions for the WoS and the 13 NSF field levels the tail exponents can go below 3.0 into the range of 2.7 to 2.8 even when a relatively short citation window is used. The difficulty one faces doing with such an analysis based on Clauset's methodology is determining if the tail of the distribution is actually a power law or some other function such as power law tail with an exponential decay, stretched exponential, etc (Clauset 2009). We are in the process of investigating this issue further. It is possible that means are an inappropriate measure for comparing population if the citation distribution has a power law tail with exponent less than 3.0. Even if the exponent is not less than 3.0 our measurement show the variance of the mean can be in the order of 10-1000 times as large as the mean as the exponent gets closer 3.0 making comparisons of means still of questionable value for evaluative purposes. On the other hand if the citation distribution is not a power law then the comparison of means maybe appropriate. A closer look at the evolution of the citation distributions over a long period of time maybe necessary before a definitive answer can be given to the question of whether "Citation distributions are so skewed that using the mean or any other central tendency measure is ill-advised." It would be interesting to hear what others have to say. References Clauset, A., Shalizi, C. S. & Newman, M. E. J. Power-law distributions in empirical data. SIAM Review 51, 661-703 (2009).
