Journal of the American Society for Information Science and Technology, 60(8), 1664-1670. Abstract: In a recently published PNAS paper, Radicchi, Fortunato, and Castellano (2008) propose the relative indicator cf as an unbiased indicator for citation performance across disciplines (fields, subject areas). To calculate cf , the citation rate for a single paper is divided by the average number of citations for all papers in the discipline in which the single paper has been categorized. cf values are said to lead to a universality of discipline-specific citation distributions. Using a comprehensive dataset of an evaluation study on Angewandte Chemie International Edition (AC-IE), we tested the advantage of using this indicator in practical application at the micro level, as compared with (1) simple citation rates, and (2) z-scores, which have been used in psychological testing for many years for normalization of test scores. To calculate zscores, the mean number of citations of the papers within a discipline is subtracted from the citation rate of a single paper, and the difference is then divided by the citations' standard deviation for a discipline. Our results indicate that z-scores are better suited than cf values to produce universality of discipline-specific citation distributions.

(2) The earlier that papers are made OA, the greater their impact. (3) High Energy Physics (HEP) researchers were among the first to make their papers OA (since 1991, and they did it without needing to be mandated to do it!) (4) Gold OA provides no further impact advantage over and above Green OA. However, the following caveats need to be borne in mind, in interpreting this paper: (a) HEP researchers have indeed been providing OA since 1991, unmandated (and computer scientists have been doing so since even earlier). But in the ensuing years, the only other discipline that has followed suit, unmandated, has been economics, despite the repeated demonstration of the Green OA impact advantage across all disciplines. So whereas still further evidence (as in this paper by Gentil-Beccot et al) confirming that OA increases impact is always very welcome, that evidence will not be sufficient to induce enough researchers to provide OA; only mandates from their institutions and funders can ensure that they do so. (b) From the fact that when there is a Green OA version available, users prefer to consult that Green OA version rather than the journal version, it definitely does not follow that journals are no longer necessary. Journals are (and always were) essentially peer-review service-providers and cerifiers, and they still are. That essential function is indispensable. HEP researchers continue to submit their papers to peer-reviewed journals, as they always did; and they deposit both their unrefereed preprints and then their refereed postprints in arxiv (along with the journal reference). None of that has changed one bit. (c) Although it has not been systematically demonstrated, it is likely that in fields like HEP and astrophysics, the journal affordability/accessibility problem is not as great as in many other fields. OA's most important function is to provide immediate access to those who cannot afford access to the journal version. Hence the Early Access impact advantage in HEP -- arising from making preprints OA well before the published version is available -- translates, in the case of most other fields, into the OA impact advantage itself, because without OA many potential users simply do not have access even after publication, hence cannot make any contribution to the article's impact. (d) Almost no one has ever argued (let alone adduced evidence) that Gold OA provides a greater OA advantage than Green OA. The OA advantage is the OA advantage, whether Green or Gold. (It just happens to be easier and more rigorous to test and demonstrate the OA advantage through within-journal comparisons [i.e Green vs. non-Green articles] than between-journal comparisons [Gold vs. non-Gold journals].) Stevan Harnad EXCERPTS: from Gentil-Beccot et al: ABSTRACT: Contemporary scholarly discourse follows many alternative routes in addition to the three-century old tradition of publication in peer-reviewed journals. The field of High- Energy Physics (HEP) has explored alternative communication strategies for decades, initially via the mass mailing of paper copies of preliminary manuscripts, then via the inception of the first online repositories and digital libraries. This field is uniquely placed to answer recurrent questions raised by the current trends in scholarly communication: is there an advantage for scientists to make their work available through repositories, often in preliminary form? Is there an advantage to publishing in Open Access journals? Do scientists still read journals or do they use digital repositories? The analysis of citation data demonstrates that free and immediate online dissemination of preprints creates an immense citation advantage in HEP, whereas publication in Open Access journals presents no discernible advantage. In addition, the analysis of clickstreams in the leading digital library of the field shows that HEP scientists seldom read journals, preferring preprints instead.... ... ...arXiv was first based on e-mail and then on the web, becoming the first repository and the first ?green? Open Access5 platform... With the term ?green? Open Access we denote the free online availability of scholarly publications in a repository. In the case of HEP, the submission to these repositories, typically arXiv, is not mandated by universities or funding agencies, but is a free choice of authors seeking peer recognition and visibility... The results of an analysis of SPIRES data on the citation behaviour of HEP scientists is presented... demonstrat[e] the ?green? Open Access advantage in HEP... With the term ?gold? Open Access we denote the free online availability of a scholarly publication on the web site of a scientific journals.... There is no discernable citation advantage added by publishing articles in ?gold? Open Access journals... ... 7. Conclusions Scholarly communication is at a cross road of new technologies and publishing models. The analysis of almost two decades of use of preprints and repositories in the HEP community provides unique evidence to inform the Open Access debate, through four main findings: 1. Submission of articles to an Open Access subject repository, arXiv, yields a citation advantage of a factor five. 2. The citation advantage of articles appearing in a repository is connected to their dissemination prior to publication, 20% of citations of HEP articles over a two-year period occur before publication. 3. There is no discernable citation advantage added by publishing articles in ?gold? Open Access journals. 4. HEP scientists are between four and eight times more likely to download an article in its preprint form from arXiv rather than its final published version on a journal web site. Taken together these findings lead to three general conclusions about scholarly communication in HEP, as a discipline that has long embraced green Open Access: 1. There is an immense advantage for individual authors, and for the discipline as a whole, in free and immediate circulation of ideas, resulting in a faster scientific discourse. 2. The advantages of Open Access in HEP come without mandates and without debates. Universal adoption of Open Access follows from the immediate benefits for authors. 3. Peer-reviewed journals have lost their role as a means of scientific discourse, which has effectively moved to the discipline repository. HEP has charted the way for a possible future in scholarly communication to the full benefit of scientists, away from over three centuries of tradition centred on scientific journals. However, HEP peer-reviewed journals play an indispensable role, providing independent accreditation, which is necessary in this field as in the entire, global, academic community. The next challenge for scholarly communication in HEP, and for other disciplines embracing Open Access, will be to address this novel conundrum. Efforts in this direction have already started, with initiatives such as SCOAP3... -------------- next part -------------- An HTML attachment was scrubbed...

Design/methodology/approach - The author uses the Scopus database and Thomson-Reuters' (earlier known as ISI) three citation databases (Science, Social Sciences and Arts & Humanities), both as implemented on the Dialog Information Services (Thomson ISI databases) and on the Web of Knowledge platform, known as Web of Science (WoS). The databases were searched to discover how many records they have for each year, how many of those have cited references for each year, and what percentage of the records have other essential or often used data elements for bibliometric/scientometric evaluation. Findings - There is no difference between the databases in the presence of publication year data all of them include this element for all the records. The presence of the language field is comparable between the Thomson and Scopus databases, but it should be noted that a 2 per cent difference for mega-databases of such size is not entirely negligible. The rate of presence of the subject category field is better in Scopus, even though it has far fewer subject categories (27) than the Thomson databases (well over 200). The rate of absence of country identification is the most critical and disappointing. It is caused primarily by the fact that journals have not had consistent policies for including the country affiliation of the authors. The huge 34 percent omission rate of country identification in Scopus also hurts its impressive author identification feature. Unfortunately, the country information is not available in more than 12 million records. Originality/value - Irrespective of the reasons for the very high rate of omission of country names or codes, it should be realised and prominently mentioned in any scientometric country reports. The author has never seen this mentioned in published papers, nor in the manuscripts that he has peer reviewed. Many can live with the low omission rates of the language, document type and subject category elements, and many can just avoid using these filters. The two factors that define the level of distortion in the assessment and ranking of the research achievements of countries are the rate of cited reference enhanced records and the rate of presence of country affiliation data.

The objective of this study is to conduct a bibliometric analysis of all ultrasound-related publications in the Science Citation Index (SCI). Method. A search on the databases of the SCI was performed covering the period of 1991-2006. All selected documents stated "ultrasound" as a part of the title, abstract, or keywords in the two fields of "acoustics" and "radiology, nuclear medicine, and medical imaging." Analyzed parameters included authorship, total number of publications in each year, document type, and the authors' keywords. The data were recorded by publication year except the authors' keywords, which were grouped into four periods: 1991- 1994, 1995-1998, 1999-2002, and 2003-2006. Results. A total of 17,775 documents were found, of which 85% were original articles. The yearly production increased from 740 (1991) to 1,208 (2006). The United States dominated with the most publications. The trend towards prenatal research declined in the last 4 years, while Doppler ultrasound research increased during 1999-2006. Conclusions. Periodic performance of bibliometric analysis of the ultrasound journals may reveal research trends. The most represented topics of ultrasound research are Doppler, prenatal diagnosis, MRI, contrast medium, and vascular studies. (C) 2009 Wiley Periodicals, Inc.

The Triple Helix approach, developed by Henry Etzkowitz and Loet Leydesdorff, is based on the perspective of University as a leader of the relationship with Industry and Government, to generate new knowledge, innovation and economic development. After Amsterdam, New York, Rio de Janeiro, Copenhagen/Lund, Turin, Singapore and Glasgow the Triple Helix movement arrives to its 8th global meeting in Madrid, Spain, in 2010. The Triple Helix VIII ? International Conference on University, Industry and Government Linkages will be held on 20-22 October 2010. It will be organized by the International Institute of Triple Helix - IITH and hosted by La Salle Innovation Park of Services for People. Its aim to connect academics, business leaders, government staff and other specialists involved in the different aspects of innovation management. The conference program will include different kinds of interactions: ? Keynote address plenary sessions with Triple Helix specialists ? Discussion panels with members of academy, industry and government ? Parallel sessions with paper presentations ? Lunch speakers ? Special sessions, dedicated to young researchers and specific themes ? Thematic workshops ? Posters and Exhibit Stand spaces ? Social program Our aim is to create the best environment to enable a fruitful discussion between academics and practitioners in the University, Industry and Government spheres. The VIII Triple Helix also will provide a unique experience of Spanish culture and heritage. The main theme of our conference is ?Triple Helix in the Development of Cities of Knowledge, Expanding Communities and Connecting Regions?. Submissions on Triple Helix related topics are encouraged and should focus on the following subthemes: - Triple Helix model - building a theory (triple helix and sustainability: triple helix twins, people circulation, spheres taking a role of the other, etc) - Triple Helix practice and experiences - TH in developing countries - The role of University in the third mission - R&D, intellectual property and technology transfer - Innovation habitat (as hybrid and consensus spaces): incubators, science & technology parks and others - Government and public policy in Triple Helix era - Regional/Local economic and social development - The future of cities in the knowledge age - Innovation as a response to the economic crisis Submission of extended abstracts is open from July, 15. All of them will be evaluated in a blind review by a scientific committee composed of international specialists in innovation management and regional development. Part of them will be accepted for parallel sessions. Others will be suggested for poster presentations. Conference Chairmen are also open to receive proposals for Thematic Workshops. These workshops will consist of four papers in specific Triple Helix topic lead by a Coordinator. This proposal has a free format and must be sent formally until November, 30. Important Deadlines: Extended abstract submission: from Jul 15 until Nov 30, 2009 Notice of acceptance Feb 28, 2010 Full paper submission (including profiles & registration): May 30, 2010 Conference: Oct 20-22, 2010 General information for submission: The extended abstract must have between 800-1000 words, including references.

[T]here is a strong skew in the distribution of citations within a journal ? typically, around 80% of the citations accrue to 20% of the articles... [W]hy then do researchers and their paymasters remain wedded to assessing individual articles by using a metric (the impact factor) that attempts to measure the average citations to a whole journal? "We?d argue that it?s primarily because there has been no strong alternative. But now alternatives are beginning to emerge... focusing on articles rather than journals... [and] not confining article-level metrics to a single indicator... Citations can be counted more broadly, along with web usage, blog and media coverage, social bookmarks, expert/community comments and ratings, and so on... "[J]udgements about impact and relevance can be left almost entirely to the period after publication. By peer-reviewing submissions purely for scientific rigour, ethical conduct and proper reporting before publication, articles can be assessed and published rapidly. Once articles have joined the published literature, the impact and relevance of the article can then be determined on the basis of the activity of the research community as a whole... [through] [a]rticle-level metrics and indicators..." Merits of Metrics. Of course direct article and author citation counts are infinitely preferable to -- and more informative than -- just a journal average (the journal "impact factor"). And yes, multiple postpublication metrics will be a great help in navigating, evaluating and analyzing research influence, importance and impact. But it is a great mistake to imagine that this implies that peer review can now be done on just a generic "pass/fail" basis. Purpose of Peer Review. Not only is peer review dynamic and interactive -- improving papers before approving them for publication -- but the planet's 25,000 peer-reviewed journals differ not only in the subject matter they cover, but also, within a given subject matter, they differ (often quite substantially) in their respective quality standards and criteria. It is extremely unrealistic (and would be highly dysfunctional, if it were ever made to come true) to suppose that these 25,000 journals are (or ought to be) flattened to provide a 0/1 pass/fail decision on publishability at some generic level, common to all refereed research. Pass/Fail Versus Letter-Grades. Nor is it just a matter of switching all journals from pass/fail to a letter grade system (A, B+, etc.), although that is effectively what the system of multiple, independent peer-reviewed journals provides. For not only do journal peer-review standards and criteria differ, but the expertise of their respective "peers" differs too. Better journals have better and more referees, exercising more rigorous peer review. (So it is not one generic journal that accepts papers for publication with grades between A+; rather there are A+ journals, B- journals, etc.) Track Records and Quality Standards. And users know all this, from the established track records of journals. Whether we like it or not, this all boils down to selectivity across a gaussian distribution of research quality in each field. There are highly selective journals, that accept only the very best papers, and even those often only after several rounds of rigorous refereeing, revision and re-refereeing; and there are less selective journals, that impose less exacting standards, all the way down to the fuzzy pass/fail threshold that distinguished refereed journals from journals whose standards are so low that they are virtually vanity-press journals. Supplement Versus Substitute. This difference (and independence) among journals in terms of their quality standards is essential if peer-review is to serve as the quality enhancer and filter that it is intended to be. Of course the system is imperfect, and, for just that reason alone (amongst many others) a rich diversity of post-publication metrics are an invaluable supplement to peer review. But they are certainly no substitute for it. Quality Distribution. On the basis of a generic 0/1 quality threshold, researchers cannot decide rationally or reliably what new research is worth the time and investment to read, use and try to build upon. Researchers differ in quality too, and they are entitled to know a priori, as they do now, whether or not a newly published work has made the highest quality cut, rather than merely that it has met some default standards, and now they must wait for the multiple post-publication metrics to accumulate in order to be able to have a more nuanced quality assessment. Rejection Rates. Minute sorting is precisely what peer review is about, and for, and especially at the highest quality levels. Although authors (knowing the quality track-records of their journals) mostly self-select, submitting their papers to journals whose standards are roughly commensurate with their quality, the underlying correlate of a journal's refereeing quality standards is basically their rejection rate: What percentage of annual papers in their subject matter would meet their standards (if all were submitted to that journal, and the only constraint was the quality level of the article, not how many articles the journal could manage to referee and publish per year)? Quality Ranges. This independent standard-setting by journals effectively ranges the 25,000 along a rough letter-grade continuum within each field, and their "grades" are roughly known by authors and users, from the journals' track-records for quality. Quality Differential. Making peer review generic would wipe out that differential quality information for new research, and force researchers at all levels to risk pot-luck with newly published research (until and unless enough time has elapsed to sort out the rest of the quality variance with post-publication metrics). Turn-Around Time. Now pre-publication peer review takes time too; but if it sorts the quality of new publications in terms known, reliable letter-grade standards (the journals' names and track-records), then it's time well spent. Offloading that dynamic pre-filtering function onto post-publication metrics, no matter how rich and plural, would greatly handicap research progress, and especially at its all-important highest quality levels. More Value From Post-Publication Metrics Does Not Entail Less Value >From Pre-Publication Peer Review. It would be ironic if the valid and timely call for a wider and richer variety of post-publication metrics -- in place of just the unitary journal average (the journal impact factor) -- were coupled with an ill-considered call for collapsing the planet's wide and rich variety of peer-reviewed journals and quality levels onto a unitary global pass/fail grade.

Design A complete citation network was constructed from all PubMed indexed English literature papers addressing the belief that ? amyloid, a protein accumulated in the brain in Alzheimer's disease, is produced by and injures skeletal muscle of patients with inclusion body myositis. Social network theory and graph theory were used to analyse this network. Main outcome measures Citation bias, amplification, and invention, and their effects on determining authority. Conclusion Citation is both an impartial scholarly method and a powerful form of social communication. Through distortions in its social use that include bias, amplification, and invention, citation can be used to generate information cascades resulting in unfounded authority of claims. Construction and analysis of a claim specific citation network may clarify the nature of a published belief system and expose distorted methods of social citation.

The case of Polywater Author(s): Diamond AM (Diamond, Arthur M., Jr.) Source: AMERICAN JOURNAL OF ECONOMICS AND SOCIOLOGY Volume: 68 Issue: 2 Pages: 387-411 Published: APR 2009 Times Cited: 0 References: 54 Abstract: Polywater, one of the most famous mistaken scientific research programs of the past half-century, is used as a case study to examine whether polywater researchers later experienced lower citation counts, or less favorable job mobility. The primary result is that simply writing on polywater, either pro or con, has a negative impact on future citations, in comparison with those who never wrote on polywater. The lifetime value of the lost citations is roughly in the range of $13,000 to $19,000. However writing on polywater did not affect the probability of a scientist leaving university employment.

Most of them are due to changes done to improve the academic impact of the open web contents and to reduce the geographical bias of search engines. As a result, the US universities still lead the Ranking (MIT with its huge Open Courseware is again the first, followed by Harvard, Stanford and Berkeley), but the digital gap with their European counterparts (Cambridge and Oxford are in the region?s top) has been reduced. Even more important, some of the developing countries institutions reach high ranks, especially in Latin America where the University of Sao Paulo (38th) and UNAM (44th) benefits from the increasingly interconnected Brazilian and Mexican academic webspaces. Several countries improves their performance including Taiwan and Saudi Arabia with strong web oriented strategies, Czech Republic (Charles), the leader for Eastern Europe, Spain (Complutense) and Portugal (Minho, Porto) with huge repositories and strong Open Access initiatives. Norway (NTNU, Oslo), Egypt could be also mentioned. On the other side, the underrated are headed by France, with a very fragmented system, Korea, whose student-oriented websites are frequently duplicated, New Zealand, India or Argentina. Africa is still monopolized by South African universities (Cape Town is the first, 405th), as well as Australian Universities are the best ranked for Oceania (Australian National University, 77th) Other well performing institutions include Cornell or Caltech in the USA, Tokyo (24th) Toronto (28th), Hong Kong (91st), or Peking (104th). On the contrary, in positions below expected we find Yale, Princeton, Saint Petersburg, Seoul and the Indian Institutes of Science or Technology.

NOV 13 2008. p.NIL_1-NIL_22 BIOMED CENTRAL LTD, LONDON ABSTRACT: Background: It has been argued that science and society are in the midst of a far-reaching renegotiation of the social contract between science and society, with society becoming a far more active partner in the creation of knowledge. On the one hand, new forms of knowledge production are emerging, and on the other, both science and society are experiencing a rapid acceleration in new forms of knowledge utilization. Concomitantly since the Second World War, the science underpinning the knowledge utilization field has had exponential growth. Few in-depth examinations of this field exist, and no comprehensive analyses have used bibliometric methods. Methods: Using bibliometric analysis, specifically first author co- citation analysis, our group undertook a domain analysis of the knowledge utilization field, tracing its historical development between 1945 and 2004. Our purposes were to map the historical development of knowledge utilization as a field, and to identify the changing intellectual structure of its scientific domains. We analyzed more than 5,000 articles using citation data drawn from the Web of Science (R). Search terms were combinations of knowledge, research, evidence, guidelines, ideas, science, innovation, technology, information theory and use, utilization, and uptake. Results: We provide an overview of the intellectual structure and how it changed over six decades. The field does not become large enough to represent with a co-citation map until the mid-1960s. Our findings demonstrate vigorous growth from the mid-1960s through 2004, as well as the emergence of specialized domains reflecting distinct collectives of intellectual activity and thought. Until the mid-1980s, the major domains were focused on innovation diffusion, technology transfer, and knowledge utilization. Beginning slowly in the mid-1980s and then growing rapidly, a fourth scientific domain, evidence-based medicine, emerged. The field is dominated in all decades by one individual, Everett Rogers, and by one paradigm, innovation diffusion. Conclusion: We conclude that the received view that social science disciplines are in a state where no accepted set of principles or theories guide research (i.e., that they are pre-paradigmatic) could not be supported for this field. Second, we document the emergence of a new domain within the knowledge utilization field, evidence-based medicine. Third, we conclude that Everett Rogers was the dominant figure in the field and, until the emergence of evidence-based medicine, his representation of the general diffusion model was the dominant paradigm in the field. -------------- next part -------------- A non-text attachment was scrubbed...

This has been done for 2,184 observational astronomy papers published between 1960 and 1964 (with 14,237 citations in 1965-1969) and the numbers looked at in various ways. The extreme dominance of California in optical astronomy and of the UK and Australia in radio astronomy provides the background against which ESO, NOAO, NRAO, and A&A were founded, with equality of access to facilities having increased enormously in the intervening 40 years, but inequality of results having increased slightly. A number of other factoids about astronomical publications, the community, and their environments surfaced during the counting process, and a subset reported here, including a few pertaining to the more distant past.

Various techniques have been developed to retrieve high quality or important articles. Some techniques rely on using the number of citations as a measurement of an article's importance. Unfortunately, citation information is proprietary, expensive, and suffers from "citation lag." MEDLINE users have a variety of information needs. Although some users require high recall, many users are looking for a "few good articles" on a topic. For these users, precision is more important than recall. We present and evaluate a method for identifying articles likely to be highly cited by using information available at the time of listing in MEDLINE. The method uses a score based on Medical Subject Headings (MeSH) terms, journal impact factor (JIF), and number of authors. This method can filter large MEDLINE result sets (>1000 articles) returned by actual user queries to produce small, highly cited result sets.

Dear Ana, Nice to hear from you. I am branching your query the eprints and dspace lists, so that those who know of other developments can post them. Although you no doubt know some of them already, five sites I suggest you have a look at are: EPrints sites: (1) IRstats: http://trac.eprints.org/projects/irstats (2) Citebase: http://citebase.eprints.org/ Other sites: (3) Citeseerx: http://citeseerx.ist.psu.edu/ (4) Publish or Perish: http://www.harzing.com/pop.htm (5) University Webometrics: http://www.webometrics.info/ I also suggest you look at the work of Johan Bollen: (who has just moved to Indiana University): http://proto.lanl.gov/jbollen/Johan_Bollen/Publications.html Mike Thelwall: http://www.scit.wlv.ac.uk/~cm1993/mycv.html Hope you are having a good summer! Tchau, Stevan
