Random sampling has a precise, technical meaning: sample units are drawn independently, and each unit in the population has an equal chance to be drawn at each stage. Independence, equal chance and the population are central issues. Leaving, independence and chance aside (most often they are violated), defining the population is central to your question. You need a clearly defined real population, or a natural chance mechanism, in order to justify random sampling - in order to claim a random sample of something manifest. Imaginary, assumed or super-populations are ill-defined and quite frankly convenient fictions because they do not have any empirical existence of their own. Random sampling from such "populations" also become fictitious as the data-generation mechanism is uncertain and assumptions become unjustifiable. In observational studies, we are often left with samples of convenience or "apparent populations" and we very seldom examine or justify the data-generation mechanism needed for a probability sample. In scientometrics we have "large" or "huge" second-order data sets that resembles "apparent populations" - we can draw random samples from these if we clearly define the population and ensures that a sampling technique, where units are drawn independently and with equal chance, is used. Using "journals", "keywords", "institutions" or the like as a selection criterion without defining a real population can easily create "selection bias" and violate the assumptions needed.

Concerning sampling. Random sampling has a precise, technical meaning: > sample units are drawn independently, and each unit in the population has an > equal chance to be drawn at each stage. > This is how I learned it. We almost never have this condition in our type of studies. For example, if one is interested in the impact of a research unit in a field of science, one does not draw randomly from the papers in this field of science, but with very precise criteria. Thus, we do not study random samples in this type of designs. Do we agree? > Independence, equal chance and the population are central issues.

For example, the journal or the field, or the country. One cannot even compute percentiles without specification of a reference set. The reference set is also needed for the specification of the expectation. Unlike biology (or medicine), we are not dealing with populations and random samples from this, but with specific--culturally meaningful--sets and subsets thereof. > Imaginary, assumed or super-populations are ill-defined and quite frankly > convenient fictions because they do not have any empirical existence of > their own. Random sampling from such "populations" also become fictitious as > the data-generation mechanism is uncertain and assumptions become > unjustifiable. > Wolfgang's point is that the means of the samples are normally distributed even if the samples are not. Thus, one can compare means as "unbiased estimators" of the distributions (using parametric statistics, e.g., the t-test). Now that I fully understand this point (given some offline conversation), I agree with it. However, one should not use means (or other central tendency statistics) for performance evaluation. (If one wishes nevertheless to use means then these means are normally distributed. :-)). Using the mean, the N in the denominator has detrimental effects on performance measurement. For example, if one compares two equally highly cited authors with equal N, and one adds to the one a number of PhD students and postdocs and not to the other, the two research groups will be very differently evaluated when using the N in the denominator. However, the less-cited papers of the juniores add to the impact of the unit. If I hit you twice, the impact is not the average of the two hits, but the sum. The surfaces beneath the citation curves have to be integrated and can then be summed and substracted. However, the integration would lead to "total cites", but this is too raw a number. By first normalizing in terms of percentages, one can make sure that top-1% is compared with top-1%, etc. Both averages and sumtotals are too crude measures. The Integrated Impact Indicator solves these issues elegantly.

These assumptions -- needed for using means -- are usually violated in empirical studies. We deliberately introduce a selection bias by using intellectual criteria. :-) This is not biology (or thermodynamics). Best wishes, Loet > Kind regards - Jesper W.

As others have pointed out, the Pareto or power-law distribution to which the citation distribution is believed to approximate, does not fall in this domain of attraction if its exponent is less than 3. Thus, the theorem is not wrong, but it's not applicable here. What does this mean in practice? Of course one can always calculate a mean number of citations for a given data sample. But if one calculates such means for different samples -- even samples drawn from the exact same underlying distribution -- one will get wildly different answers. Indeed, it can be shown that the values of the mean themselves follow a power law under these circumstances, and hence can themselves vary over orders of magnitude. When people say the mean is invalid, this is what they are referring to. You may calculate a mean from this year's data and get a value of 1, then calculate it again for next year's and get a value of 100. Under such conditions, it does seem ill-advised to impute much meaning to such measurements.

Understanding the characteristics of research interests from previous publications may help to provide better services for scientists in the Web age. In this paper, we introduce some parameters to track the evolution process of research interests, we analyze their structural and dynamic characteristics. According to the observed characteristics of research interests, under the framework of unifying search and reasoning (ReaSearch), we propose interests-based unification of search and reasoning (I-ReaSearch). Under the proposed I- ReaSearch method, we illustrate how research interests can be used to improve literature search on the Web. According to the relationship between an author's own interests and his/her co-authors interests, social group interests are also used to refine the literature search process. Evaluation from both the user satisfaction and the scalability point of view show that the proposed I- ReaSearch method provides a user centered and practical way to problem solving on the Web. The efforts provide some hints and various methods to support personalized search, and can be considered as a step forward user centric knowledge retrieval on the Web. From the standpoint of the Active Media Technology (AMT) on the Wisdom Web, in this paper, the study on the characteristics of research interests is based on complex networks and human dynamics, which can be considered as an effort towards utilizing information physics to discover and explain the phenomena related to research interests of scientists. The application of research interests aims at providing scientific researchers best means and best ends in an active way for literature search on the Web.

This paper proposes a method of measuring the relatedness among sets of academic papers in order to detect unrelated communities which are not related to target topic. A citation network, extracted by given keywords, is divided into communities based on the density of links. We measured and compared four measures of relatedness between two communities in a citation network for three large- scale citation datasets. We used both link and semantic similarities. The topological distance from the center in a citation network is a more efficient measure for removing the unrelated communities than the other three measures: the ratio of the number of intercluster links over the all links, the ratio of the number of common terms over all terms, cosine similarity of tf-idf vectors.

Almost 5,300 bibliographic database records for publications explicitly citing at least one of two papers by John Nash and/or using the phrase "Nash Equilibrium/Nash Equilibria" were retrieved from the Web of Science and various subject-related databases. Breadth of influence is demonstrated by the wide variety of subject areas in which Nash Equilibrium- related publications occur, including in the natural and social sciences, humanities, law, and medicine. Fifty percent of all items have been published since 2002, suggesting that Nash's papers have experienced "delayed recognition." A degree of Obliteration by Incorporation is observed in that implicit citations (use of the phrase without citation) increased over the time period studied, although the proportion of all citations that are implicit has remained relatively stable during the most recent decade with an annual rate of between 60% and 70%; subject areas vary in their level of obliteration.

We adopt a portfolio of measures approach, using the Hirsch family of statistics to assess ideational influence and Social Network Analysis centrality measures for social influence to profile Heinz Klein's contribution to information systems (IS) research. The results show that Heinz was highly influential in both ideational terms (a significant body of citations) and social terms (he is close to the heart of the IS research community). Reflecting on the major research themes and scholarly values espoused by Klein we define a 'Kleinian view of IS research', grounded in Habermas' Theory of Communicative Action, and use that to frame four affirmative propositions to address what we observe to be a distortion and attenuation of the academic discourse on the evaluation of scholarly production. This paper argues that focus should be shifted from the venue of publication of the research to the uptake of the ideas contained in it, thus increasing the openness of the discourse, participation in the discourse, truthfulness, and reduction of the inequities in power distribution within academia.

Would anyone on the list care to comment? Ok, you asked! George Monbiot, though he puts it a bit shrilly, is basically right: In the online era, peer-reviewed journal subscriptions are blocking the access to -- and hence the usage and impact of -- research that researchers wish to give away to all potential users for free, seeking no revenue from its sales, just the impact of its uptake and usage in further research. While subscriptions are still paying the bill, the solution is for all researchers to self-archive all their final refereed drafts in their institutional repositories, free for all, immediately upon acceptance for publication. (This is called "Green Open Access".) This should be mandated by all research institutions and funders to generate universal OA. If and when universal Green OA makes subscriptions unsustainable as the means of recovering the costs of peer-reviewed publication, the print and online edition and their costs can be phased out, all access-provision and archiving and their costs can be offloaded onto the distributed worldwide network of Green OA Institutional Repositories, and journals can convert to ("Gold") OA publishing, recovering their sole remaining cost (peer review) via a small per-submission fee to the author's institution -- easily covered out of just a fraction of each institution's annual windfall subscription cancelation savings. (Peers review for free too.) And if that went by too fast, here it is longhand, many times over: Harnad, S. (2007)?The Green Road to Open Access: A Leveraged Transition. In: Anna Gacs.

In interviews presented here, the editors recount the history of the association, the journal, and the field as they experienced it. Using a variety of sources, the author provides additional context for their remarks, describing the pioneering efforts of early evaluation associations, the contentious mergers that resulted in a single national association, the emergence of dedicated evaluation publications, and the challenges posed by an increasingly diverse membership. The author concludes by discussing the ways in which the editors, throughout their 35 years of service, strengthened not only professional associations but the larger field of evaluation.

Factors determining choice of an academic career in neurological surgery are unclear. This study seeks to evaluate the graduates of medical schools and US residency programs to determine those programs that produce a high number of graduates remaining within academic programs and the contribution of these graduates to academic neurosurgery as determined by h-index valuation. Methods. Biographical information from current faculty members of all accredited neurosurgery training programs in the US with departmental websites was obtained. Any individual who did not have an American Board of Neurological Surgery certificate (or was not board eligible) was excluded. The variables collected included medical school attended, residency program completed, and current academic rank. For each faculty member, Web of Science and Scopus h-indices were also collected. Results. Ninety-seven academic neurosurgery departments with 986 faculty members were analyzed. All data regarding training program and medical school education were compiled and analyzed by center from which each faculty member graduated. The 20 medical schools and neurosurgical residency training programs producing the greatest number of graduates remaining in academic practice, and the respective individuals' h-indices, are reported. Medical school graduates of the Columbia University College of Physicians and Surgeons chose to enter academics the most frequently. The neurosurgery training program at the University of Pittsburgh produced the highest number of academic neurosurgeons in this sample. Conclusions. The use of quantitative measures to evaluate the academic productivity of medical school and residency graduates may provide objective measurements by which the subjective influence of training experiences on choice of an academic career may be inferred. The top 3 residency training programs were responsible for 10% of all academic neurosurgeons. The influence of medical school and residency experiences on choice of an academic career may be significant.

Results show that research unit size does not influence total scientific output, but rather the scientific output profile of individual academics. Upon disaggregating the output we find that academics at larger research units publish more in international than in national peer- reviewed journals. This suggests that research unit size positively affects international visibility, a venue that may proxy for research quality. The analysis also shows that as research unit size increases, it influences academics' overall communication. Most importantly, the academics' information exchange with peers at both national and international levels is highest at larger research units, suggesting that research unit size facilitates contact with academics at both national and international institutions.

We develop and test a model that predicts how individual characteristics and organizational factors affect individual patenting production. The analysis uses zero-inflated negative binomial regression on data from a 2010 national survey of 1,379 US-based university scientists and engineers, 624 of which hold no patents assigned to their current university. Findings from this research generally support our hypotheses that individual and organizational factors are associated with individual patent production. We find that while university patent policy and university technology transfer offices may be important for encouraging or discouraging scientists to patent the first time, department incentives and individual preferences and characteristics predict the number of patents that faculty produce. This research supports prior literature and develops new perspectives on how universities and policy-makers can understand and shape how individual and organizational constraints and incentives affect patent productivity.

We aimed to investigate the research output in public health from 3 major regions of China: mainland China (ML), Hong Kong (HK) and Taiwan (TW). Material/Methods: We retrieved papers published in 105 public health-related journals from ML, HK and TW with the applications of the ISI Web of Knowledge database. The total papers, impact factor, times cited, papers published in the highest impact factor journals, and most often published journals were analyzed for quantity and quality comparisons among the 3 regions. Results: Totally, 2587 papers were published during 1999-2008, including 1089 (42.1%) from ML, 471 (18.2%) from HK, and 1027 (39.7%) from TW. The total annual number of papers from the 3 regions increased significantly, from 140 in 1999 to 424 in 2008. The average impact factor of papers from TW (2.588) was higher than those from HK (2.531) and ML (1.568). The average number of times cited of each paper from TW was 8.84, followed by 8.34 from HK and 5.90 from ML. Excluding publications in Biomedical and Environmental Sciences, papers from ML had higher average IF and average times cited. TW had the most articles published in the highest impact factor journals, and HK had the highest total IF of most often published journals. Conclusions: The total number of papers in public health from China increased significantly during 1999-2008. ML contributed the highest annual paper output compared with HK and TW, but papers from ML are more often locally published and less frequently cited.

Some improvements of our previous mapping approaches Lutz Bornmann and Loet Leydesdorff Bornmann and Leydesdorff (in press) proposed methods based on Web-of-Science data to identify field-specific excellence in cities where highly-cited papers were published more frequently than can be expected. Top performers in output are cities in which authors are located who publish a number of highly-cited papers that is statistically significantly higher than can be expected for these cities. Using papers published between 1989 and 2009 in information science improvements to the methods of Bornmann and Leydesdorff (in press) are presented and an alternative mapping approach based on the indicator I3 is introduced here.

Is Percentile-Based Impact Factor a Solution? (Editorial Material, English) AUTHOR: Labadie, RF; Fitzpatrick, JM SOURCE: OTOLARYNGOLOGY-HEAD AND NECK SURGERY 145 (1). JUL 2011. p.15-17 SAGE PUBLICATIONS LTD, LONDON KEYWORDS: impact factor; surgical specialty fields KEYWORDS+: DOCUMENTATION ABSTRACT: Impact factor (IF) consists of reporting the number of references an average article in a given journal receives over a 2-year period. Despite several valid criticisms, IF has become an important component of academic advancement. The authors sought to investigate the possible relationship between size of specialty field and IF. The top 10 journals of 13 specialty fields were selected based on IF as reported by Journal Citations Reports on the Web of Science. Specialty field population was obtained from the American Board of Medical Specialties. A highly positive correlation (r = 0.9) was noted with smaller fields (eg, otolaryngology) having lower IFs. To overcome this population bias, a percentile-based impact factor (PIF) may be used where the top journal within a field is given 100%, the worst 0%, and all other journals' IFs are proportionately scaled in between the 2 extremes. PIF acts to "level the playing field," allowing between-specialty field comparisons.

Design/methodology/approach - An environmental scan of the web was conducted to find sample health websites for teens. Inlink data was gathered using Google Webmaster Tools, and the inlink sources were classified by the type of creator. Findings - The teen health websites in this study had a low level of visibility on the web compared to general health web portals (such as Medline Plus, for example) and a weak level of referrals from health- related groups compared to other organisations such as schools and public libraries. Many non-healthcare related websites are linking to teen health information, demonstrating that teens' health information needs are being met by sources that lack expertise in health care. Research limitations/implications - Due to the small sample of six websites, generalisations beyond the context of the study are difficult to infer. The Google Webmaster inlink tool does not guarantee 100 per cent coverage and some inlinks may not have been captured by the tool, although this number is most likely minimal. The results of this study present a snapshot rather than an all-inclusive view of the visibility of teen health websites and offer a starting point for further investigation. Practical implications - The weak network of inlinks leading from reliable health care providers is a lost opportunity for health care professionals to reach young people. Social implications - Due to the weak network of inlinks from reliable health information sources, teens may not be accessing accurate and reliable health information. This could have a potential cost in terms of health outcomes. Originality/value - The study investigates health information for teens, a population that increasingly uses the web as a source for health information. The authors used an approach that has not been used before in the study of teens and health information on the web.

It investigates Iran's performance in its national journal set, and proposes a more prominent journal subset. Design/methodology/approach - A citation analysis method is applied to study Iran's scientific performance in its national journal set. The data were extracted from the Science Citation Index at Web of Science and JCR and imported to SPSS for further refinement and analysis. Findings - The results showed that Iran experienced comparatively considerable citation loss. Surplus citations are concentrated in a small number of journals, presented as Iran's positive Matthew core journals. The results also confirm a relatively poor publication strategy adopted by Iranian scientists and that a publication concentration does not necessarily enhance the chance of being widely cited. Research limitations/implications - These findings imply that Iran needs to watch more vigilantly the functioning of its science system. To improve its presence at the international level, Iran should re-orient its publication strategy towards a more prominent one. This may be the case for similar science systems, where the emphasis is given to quantity rather than quality. Originality/value - Country-specific Matthew core journals, with serious citation competition, can serve as an important criterion to monitor the functioning of science systems regarding publication strategy. This is the first empirical study to employ the concept to suggest improvements in a country's publication strategy. AUTHOR ADDRESS: H Sotudeh, Shiraz Univ, Dept Lib & Informat Sci, Shiraz, Iran -------------------------------------------------------------------------- TITLE: The h-index, h-core citation rate and the bibliometric profile of the Scopus database (Article, English) AUTHOR: Jacso, P SOURCE: ONLINE INFORMATION REVIEW 35 (3). 2011. p.492-501 EMERALD GROUP PUBLISHING LIMITED, BINGLEY SEARCH TERM(S): HIRSCH JE P NATL ACAD SCI USA 102:16569 2005; BIBLIOMETR* item_title; CITATION item_title; CITATION* item_title KEYWORDS: Serials; Very large databases; Research work KEYWORDS+: SCIENTIFIC-RESEARCH OUTPUT; WEB-OF-SCIENCE; GOOGLE SCHOLAR; INFORMATION-SCIENCE; IMPACT; CONS; PROS; PRODUCTIVITY; RESEARCHERS; INDICATORS ABSTRACT: Purpose The h-index has been used to evaluate research productivity and impact (as manifested by the number of publications and the number of citations received) at many levels of aggregations for various targets. The purpose of this paper is to examine the bibliometric characteristics of the largest multidisciplinary databases that are the most widely used for measuring research productivity and impact. Design/methodology/approach - The paper presents preliminary findings about the Scopus database. It is to be complemented and contrasted by the bibliometric profile of the Web of Science (WoS) database. Findings - The test results showed that 18.7 million Scopus records had one or more cited references, representing 42 per cent of the entire database content. The ratio of cited reference enhanced records kept slightly increasing year by year from 1996 to 2009. Scopus classifies the journals and other serial sources into 27 broad subject areas by assigning its journals to 21 science disciplines, four social science disciplines, a single Arts and Humanities category, and/or a multidisciplinary category. The distribution of records among the broad subject areas can be searched in Scopus using the four-character codes of the subject areas. A journal or a single primary document may be assigned to more than one subject area. However, Scopus overdoes this, and it significantly distorts the h-index for the broad subject areas. The h- index of the pre-1996 subset of records for the 21,066,019 documents published before 1996 is 1,451, i.e. there are records for 1,451 documents in that subset that were cited more than 1,450 times. The total number of citations received by these 1,451 papers (i.e. the h-core, representing the number of items that contribute to the h-index) is 4,416,488, producing an average citation rate of 3,044 citations per item in the h-core of the pre-1996 subset of the entire Scopus database. For the subset providing records for 23,455,354 documents published after 1995, the h-index is 1,339, so the total number of citations must be at least 1,792,921. In reality the total number of citations received by these papers is 3,903,157, yielding a citation rate of 2,915 citations per document in the h-core. For the entire Scopus database of 44.5 million records the h-index is 1,757. Originality/value - Knowing the bibliometric features of databases, their own h-index and related metrics versus those of the alternative tools can be very useful for computing a variety of research performance indicators. However, we need to learn much more about our tools in our rush to metricise everything before we can rest assured that our gauges gauge correctly or at least with transparent limitations. Learning the bibliometric profile of the tools used to measure the research performance of researchers, departments, universities and journals can help in making better informed decisions, and discovering the limitations of the measuring tools.

SEP 2011. p.1727-1740 WILEY-BLACKWELL, MALDEN SEARCH TERM(S): CITATION* item_title KEYWORDS+: ABSORPTIVE-CAPACITY; KNOWLEDGE FLOWS; SCIENCE; TECHNOLOGIES; INDICATE; LEVEL; ART ABSTRACT: Patent citations added by examiners are often used as indicators of technological impact and knowledge flows, despite various criticisms. In this study we analyze the distribution of examiner patent citations according to patent characteristics in order to show their limitations. According to our findings, the number of applicant citations included is dependent on the science-base of the technology. However, this gets masked by the citations added by patent examiners, who smooth the distribution of citations across technology classes and include the same number of citations regardless of whether applicants cite any references. Some researchers have called for the use of applicant rather than examiner patent citations as indicators of technology impact and knowledge flows. Nevertheless, we show that the former also have important caveats, because applicants may increase the number of citations in international patents and when there are coapplicants. The implication is that analysts should consider a context-driven use of citation-based indicators.

It is therefore tempting (and many authors gave in to temptation) to use the same method for computing rankings of scientists and rankings of departments. Depending on the method, this can yield quite surprising and unpleasant results. Indeed, with some methods, it may happen that the "best" department contains the "worst" scientists, and only them. This problem will not occur if the rankings satisfy a property called consistency, recently introduced in the literature. In this article, we explore the consequences of consistency and we characterize two families of consistent rankings.

These types of papers are often cited more frequently. To identify the coauthorship trends within Library and Information Science (LIS), this study analyzed 7,489 papers published in six leading publications (ARIST, IP&M, JAMIA, JASIST, MISQ, and Scientometrics) over the last three decades. Logistic regression tested the relationships between citations received and seven factors: authorship type, author's subregion, country income level, publication year, number of authors, document type, and journal title. The main authorship type since 1995 was national collaboration. It was also the dominant type for all publications studied except ARIST, and for all regions except Africa. For citation counts, the logistic regression analysis found all seven factors were significant. Papers that included international collaboration, Northern European authors, and authors in high-income nations had higher odds of being cited more. Papers from East Asia, Southeast Asia, and Southern Europe had lower odds than North American papers. As discussed in the bibliometric literature, Merton's Matthew Effect sheds light on the differential citation counts based on the authors' subregion. This researcher proposes geographies of invisible colleagues and a geographic scope effect to further investigate the relationships between author geographic affiliation and citation impact.

This article utilizes academic genealogy network data from 3,038 PhD dissertations in Library and Information Science (LIS) over a span of 80 years (1930-2009) to describe interdisciplinary changes in the discipline. Aspects of academic pedigree of advisors and committee members are analyzed, such as country, school, and discipline of highest degree, to reveal the interdisciplinary features of LIS. The results demonstrate a strong history of mentors from fields such as education and psychology, a decreasing trend of mentors with LIS degrees, and an increasing trend in mentors receiving degrees in computer science, business, and communication, among other disciplines. This work proposes and explores the use of academic genealogy as an indicator of interdisciplinarity and calls for additional research on the role of doctoral committee composition in a student's subsequent academic career.

However, citation distributions are skewed, and the average has the disadvantage that the number of publications is used in the denominator. Using hundred percentiles, one can integrate the normalized citation curve and develop an indicator that can be compared across document sets because percentile ranks are defined at the article level. I apply this indicator to the set of 58 journals in the ISI Subject Category of "Nanoscience & nanotechnology," and rank journals, countries, cities, and institutes using non-parametric statistics. The significance levels of results can thus be indicated. The results are first compared with the ISI-Impact Factors, but this Integrated Impact Indicator (I3) can be used with any set downloaded from the (Social) Science Citation Index. The software is made publicly available at the Internet. Visualization techniques are also specified for evaluation by positioning institutes on Google Map overlays. http://arxiv.org/ftp/arxiv/papers/1109/1109.2306.pdf ** apologies for cross postings. _____ Loet Leydesdorff Professor, University of Amsterdam Amsterdam School of Communications Research (ASCoR) Kloveniersburgwal 48, 1012 CX Amsterdam.

Methods: The Institute for Scientific Information Web of Knowledge Database and the Journal Citation Report Science Editions were used to retrieve the. 100 most cited articles published in journals dedicated to endodontics. The top-cited articles were selected and analyzed with regard to journals, authors, institution, country of origin, publication title and year, number of citations, article type, study design, level of evidence, and field of study. Results: The top 100 articles were cited between 87 and 554 times. These articles appeared in 4 different journals, with more than half in the Journal of Endodontics, followed by the journals Oral Surgery Oral Medicine Oral Pathology Oral Radiology and Endodontology, the International Endodontic Journal, and Endodontics & Dental Traumatology. Forty-eight articles were published between 1990 and 1999. All articles were published in English and primarily originated from the United States (n = 52). The majority of articles were basic science articles (n = 55), followed by clinical research studies (n = 28) and nonsystematic reviews (n = 17). Uncontrolled case series with level IV of evidence and narrative reviews with level V of evidence were the most frequent types of study design. The main topics covered by the top-cited articles were microleakage and endodontic microbiology. Conclusions: This analysis of citation rates reveals useful and interesting information about scientific progress in the field of endodontics. Basic research and observational studies published in high-impact endodontic journals had the highest citation rates.

The Social sciences are dominated by Economics. The IPCC assessment also results in the separation of the Earth, Biological and Social sciences. The integration that occurs is mainly between closely related scientific fields. The research community consequently imposes a physical and economic bias and a separation of scientific fields that the IPCC reproduces in the policy sphere. It is argued that this physical and economic bias distorts a comprehensive understanding of climate change and that the weak integration of scientific fields hinders climate change from being fully addressed as an integral environmental and social problem. If climate change is to be understood, evaluated and responded to in its fullness, the IPCC must broaden its knowledge base and challenge the anthropocentric worldview that places humans outside of nature.

On the contrary, in schools with low starting levels students make more progress than in schools with higher starting levels. On the other hand, the analyses do show a widening gap between students with well educated and poorly educated parents. The gap between delayed and accelerated students was found to increase as well, but the initial disadvantage of boys was found to disappear.

The tool is designed for researchers and science policy makers interested to study and understand the structure and dynamics of science. It is a standalone desktop application that installs and runs on Windows, Linux x86 and Mac OSX and supports: * Reading and writing of 20 major bibliometric file formats (e.g., ISI, Scopus, bibtex, nsf, EndNote, CSV, Pajek .net, XGMML, GraphML), * Easy access to more than 180 algorithms for the temporal, geospatial, topical, and network analysis and visualization of scholarly datasets at the micro (individual), meso (local), and macro (global) levels, and * Professional visualization of analysis results by means of large-format charts and maps. The first hour of the tutorial provides a basic introduction of the tool. Remaining time will be spent discussing sample workflows featured in the Sci2 Tutorial at (http://sci2.wiki.cns.iu.edu) and new functionality such as the Yahoo! geocoder, geospatial data aggregation by congressional district, network clustering and backbone identification algorithms, and the analysis and visualization of evolving networks. The Sci2 tool is actively used by the National Science Foundation, the National Institutes of Health, the US Department of Agriculture, and some private foundations. While different agencies might not be able to share internal data sets, they can compare the results of replicable workflows, e.g., to understand and coordinate funding priorities across agencies. *Reference* B?rner, Katy.

AUG 2011. p.1933-1963 AMER ECONOMIC ASSOC, NASHVILLE SEARCH TERM(S): GARFIELD E rauth; MERTON RK rauth; PRICE DJD rauth; GARFIELD E SCIENTOMETRICS 1:359 1979 KEYWORDS+: RESEARCH-AND-DEVELOPMENT; INTELLECTUAL PROPERTY; TECHNOLOGICAL-CHANGE; PATENT CITATIONS; CELL-LINES; INNOVATION; KNOWLEDGE; SCIENCE; MODELS; GROWTH ABSTRACT: While cumulative knowledge production is central to growth, little empirical research investigates how institutions shape whether existing knowledge can be exploited to create new knowledge. This paper assesses the impact of a specific institution, a biological resource center, whose objective is to certify and disseminate knowledge. We disentangle the marginal impact of this institution on cumulative research from the impact of selection, in which the most important discoveries are endogenously linked to research-enhancing institutions. Exploiting exogenous shifts of biomaterials across institutional settings and employing a difference-in-differences approach, we find that effective institutions amplify the cumulative impact of individual scientific discoveries.

Out of a total of 3,342 citations, 756 (22.62%) were from German authors with 248 (32.8) self-citations. The hegemony of the impact factor in science, research and education is critically discussed. The imbalance between the number of surgeons in the US and United Kingdom (66,032) and surgeons in the German speaking countries in Europe (25,300) is compared with respect to the counting methods used to create the impact factor of a journal. The creation of an independent impact factor in Europe and the development of an EU-based citation data bank which allows unselected access to national language scientific literature are strongly needed.

SEP 2011. p.380-397 SAGE PUBLICATIONS INC, THOUSAND OAKS SEARCH TERM(S): MERTON RK rauth KEYWORDS: paradigm; Kuhn; discovery; theory; exemplar; theory change ABSTRACT: I present a history of Kuhn's discovery of paradigms, one that takes account of the complexity of the discovery process. Rather than emerging fully formed in Structure, the concept paradigm emerged through a series of phases. Early criticism of Structure revealed that the role of paradigms was unclear. It was only as Kuhn responded to criticism that he finally articulated a precise understanding of the concept paradigm. In a series of publications in the 1970s, he settled on a conception of a paradigm as a concrete exemplar that functions as a guide to future research.

The associated "Heaps process" is the stochastic process tracking the fraction of different element copies present in the evolving ensemble at any given time point. For example, the evolving ensemble is a text assembled from a stream of words, and the Heaps process keeps count of the number of different words in the evolving text. A detailed asymptotic statistical analysis of the Heaps process, in the limit n -> infinity, is conducted. This paper establishes a comprehensive "Heapsian analysis" of the growth statistics of Zipfian ensembles. The analysis presented far extends and generalizes Heaps' law, which asserts that the number of different words in a text of length I follows a power law in the variable I. (C) 2011 Elsevier B.V.

This article compares the evaluation procedures in use in the UK (the Research Assessment Exercise introduced in 1986), in Italy (the Valutazione Triennale della Ricerca conducted between 2001 and 2003) and in Germany (the Excellenz Initiative launched by the Federal Government; the Ranking of institutions and disciplines by the German Science Council both started in 2004). It analyses these reforms with the help of two ideal-types defined from the knowledge base and the link between such knowledge and public action (Glaser, 2007; Whitley, 2007; Glaser, Lange et al., 2010). National evaluation systems can be predominantly qualified as intrusive evaluation systems or "competitive evaluation systems" with a strong or weak impact on research. However, various forms of hybridization reveal the tensions inherent to all research evaluation systems and the difficult decisions as to which kinds of knowledge which should be given priority.

But I contend that even an imperfect law is better than no law. Replacing this rigid evaluation system with a more flexible one could send Chinese academia into chaos. Leaders of universities and research institutions could then establish their own evaluation systems, designing them to favour their particular interests. For example, a professor who is connected to a scientific journal might be tempted to rank papers published in that journal more highly when evaluating the performance of his or her university. Chinese researchers should benefit from the strict implementation of impact-factor evaluation criteria. But the rewards for meeting these targets aren't always forthcoming. A good relationship with the few leading executives who control China's academia is also important, as it is for gaining access to the best scientific projects and for promotions. The key task is therefore to eradicate this autocratic control. Researchers would then be able to concentrate solely on their work.

Methods: The Institute for Scientific Information Web of Knowledge Database and the Journal Citation Report Science Editions were used to retrieve the. 100 most cited articles published in journals dedicated to endodontics. The top-cited articles were selected and analyzed with regard to journals, authors, institution, country of origin, publication title and year, number of citations, article type, study design, level of evidence, and field of study. Results: The top 100 articles were cited between 87 and 554 times. These articles appeared in 4 different journals, with more than half in the Journal of Endodontics, followed by the journals Oral Surgery Oral Medicine Oral Pathology Oral Radiology and Endodontology, the International Endodontic Journal, and Endodontics & Dental Traumatology. Forty-eight articles were published between 1990 and 1999. All articles were published in English and primarily originated from the United States (n = 52). The majority of articles were basic science articles (n = 55), followed by clinical research studies (n = 28) and nonsystematic reviews (n = 17). Uncontrolled case series with level IV of evidence and narrative reviews with level V of evidence were the most frequent types of study design. The main topics covered by the top-cited articles were microleakage and endodontic microbiology. Conclusions: This analysis of citation rates reveals useful and interesting information about scientific progress in the field of endodontics. Basic research and observational studies published in high-impact endodontic journals had the highest citation rates.

OCT 2011. p.1-36 SPRINGER, DORDRECHT SEARCH TERM(S): PRICE DJD rauth KEYWORDS: Bibliometrics; Entrepreneurship; Invisible college KEYWORDS+: INVISIBLE COLLEGE; COCITATION ANALYSIS; SOCIAL-SCIENCE; CITATION; FUTURE; COMMUNICATION; SCHOLARSHIP; NETWORK; NANOTECHNOLOGY; BIBLIOMETRICS ABSTRACT: Despite the vitality and dynamism that the field of entrepreneurship has experienced in the last decade, the issue of whether it comprises an effective network of (in)formal communication linkages among the most influential scholars within the area has yet to be examined in depth. This study follows a formal selection procedure to delimit the 'relational environment' of the field of entrepreneurship and to analyze the existence and characterization of (in)visible college(s) based on a theoretically well-grounded framework, thus offering a comprehensive and up-to-date empirical analysis of entrepreneurship research. Based on more than a 1,000 papers published between 2005 and 2010 in seven core entrepreneurship journals and the corresponding (85,000) citations, we found that entrepreneurship is an (increasingly) autonomous, legitimate and cohesive (in)visible college, fine tuned through the increasing visibility of certain subject specialties (e.g., family business, innovation, technology and policy). Moreover, the rather dense formal links that characterize the entrepreneurship (in)visible college are accompanied by a reasonably solid network of informal relations maintained and sustained by the mobility of 'stars' and highly influential scholars. The limited internationalization of the entrepreneurship community, reflected in the almost total absence of non- English-speaking authors/studies/outlets, stands as a major quest for the field.

A network analysis was performed to examine the special structure and we compare state of the networks in different periods to determine how the network has got such properties. The dataset are get from the reference relationship in literature on important Chinese academic journals from 1980 to 2010. The analytical results reveal the hidden network structure of interdisciplinary knowledge flows in China and demonstrate that the network is highly connected and has a homogeneous link structure and heterogeneous weight distribution. Through comparing of the network in three periods, that is 1981-1990, 1991-2000 and 2001-2010, we find that the special evolution process, which is limited by the number of nodes, play an important influence on interdisciplinary knowledge flows.

Using bibliometric data of the Institute of Scientific Information, we analyzed the number of scientific articles published in international peer-reviewed journals between 1991 and 2010 for Vietnam, Cambodia, Laos, Thailand, Myanmar, Malaysia, Indonesia, Brunei, the Philippines, and Singapore. During the 20-year period, scientists from the ASEAN countries have published 165,020 original articles in ISI indexed journals, which represents similar to 0.5% of the world scientific output. Singapore led the region with the highest number of publications (accounting for 45% of the countries' total publications), followed by Thailand (21%), Malaysia (16%), Vietnam (6%), Indonesia and the Philippines (5% each). The number of scientific articles from those countries has increased by 13% per year, with the rate of increase being highest in Thailand and Malaysia, and lowest in Indonesia and the Philippines. At the country level, the correlation between knowledge economy index and scientific output was 0.94. Based on the relationship between scientific output and knowledge economy, we identified 4 clusters of countries: Singapore as the first group; Thailand and Malaysia in the second group; Vietnam, Indonesia and the Philippines in the third group; and Cambodia, Laos, Myanmar and Brunei in the fourth group. These data suggested that there was a strong relationship between scientific research and the degree of "knowledgization" of economy.

OCT 2011. p.119-138 SPRINGER, DORDRECHT SEARCH TERM(S): CITATION item_title; CITATION* item_title KEYWORDS: Co-author network; Citation network; Nano technology KEYWORDS+: SMALL-WORLD NETWORKS; COMPLEX NETWORKS; WIDE-WEB; DYNAMICS; INTERNET ABSTRACT: Research activities and collaborations in nanoscale science and engineering have major implications for advancing technological frontiers in many fields including medicine, electronics, energy, and communication. The National Nanotechnology Initiative (NNI) promotes efforts to cultivate effective research and collaborations among nano scientists and engineers to accelerate the advancement of nanotechnology and its commercialization. As of August 2008, there have been over 800 products considered to benefit from nanotechnology directly or indirectly. However, today's accomplishments in nanotechnology cannot be transformed into commercial products without productive collaborations among experts from disparate research areas such as chemistry, physics, math, biology, engineering, manufacturing, environmental sciences, and social sciences. To study the patterns of collaboration, we build and analyze the collaboration network of scientists and engineers who conduct research in nanotechnology. We study the structure of information flow through citation network of papers authored by nano area scientists. We believe that the study of nano area co-author and paper citation networks improve our understanding of patterns and trends of the current research efforts in this field. We construct these networks based on the publication data collected for years ranging 1993 through 2008 from the scientific literature database "Web of Science". We explore those networks to find out whether they follow power-law degree distributions and/or if they have a signature of hierarchy. We investigate the small- world characteristics and the existence of possible community structures in those networks. We estimate the statistical properties of the networks and interpret their significance with respect to the nano field.

OCT 2011. p.139-152 SPRINGER, DORDRECHT SEARCH TERM(S): WENNERAS C NATURE 387:341 1997 KEYWORDS: Women scientists; Russia; Bibliometrics; Surnames; Citations KEYWORDS+: GENDER-GAP; SCIENTIFIC PRODUCTIVITY; BIBLIOMETRIC ANALYSIS; CANCER-RESEARCH; SCIENCE; WOMEN; TECHNOLOGY; AUTHORSHIP; JOURNALS; CITATION ABSTRACT: This study is based on the fact that the surnames of many Russian scientists have gender endings, with "a" denoting a female, so that the sex of most of them can be readily determined from the listing of authors in the Web of Science (WoS). A comparison was made between the proportion of females in 1985, 1995, and 2005, with a corresponding analysis of the major fields in which they worked, their propensity to co- author papers internationally (which often necessitates having the opportunity to travel to conferences abroad to meet possible colleagues), and their citation records. We found, as expected, that women had a higher presence in the biological sciences and a very low presence in engineering, mathematics, and physics. Their citation scores, on a fractionated basis, were lower than those for men in almost all fields and years, and were not explained by their writing of fewer reviews and papers in English (both of which lead to higher citations), or their lower amount of international collaboration in 1995 and 2005 after Russia had become a more open society.

The effects of "delayed recognition" on impact indicators have importance and are of interest not only to bibliometricians but also among research managers and scientists themselves. It has been suggested that the "Mendel syndrome" is a potential drawback when assessing individual researchers through impact measures. If publications from particular researchers need more time than "normal" to be properly acknowledged by their colleagues, the impact of these researchers may be underestimated with common citation windows. In this paper, we answer the question whether the bibliometric indicators for scientists can be significantly affected by the Mendel syndrome. Applying a methodology developed previously for the classification of papers according to their durability (Costas et al., J Am Soc Inf Sci Technol 61(8):1564-1581, 2010a; J Am Soc Inf Sci Technol 61(2):329-339, 2010b), the scientific production of 1,064 researchers working at the Spanish Council for Scientific Research (CSIC) in three different research areas has been analyzed. Cases of potential "Mendel syndrome" are rarely found among researchers and these cases do not significantly outperform the impact of researchers with a standard pattern of reception in their citations. The analysis of durability could be included as a parameter for the consideration of the citation windows used in the bibliometric analysis of individuals.

Unfortunately, there is a surprising lack of consensus on productivity's meaning, measurement, and how to compare the productivity of one academic psychologist to another. In the present study, we review academic productivity research within psychology, and using a sample of 673 psychologists, compute six indexes of productivity. Most productivity metrics (publication count, citation count, or some combination of the two) were substantially interrelated and one (Integrated Research Productivity Index) was independent from years in the field. Female psychologists were equally as productive as male psychologists after accounting for years in the field, and pre-tenure psychologists showed steeper change-over-time productivity slopes than post-tenure psychologists. Based on these findings, we provide recommendations for the use and measurement of academic research productivity.

This longitudinal study allows us to analyse developmental trends over times in different subject areas with distinct citation and publication patterns. To this aim, we first introduce an axiomatic index of the overall prestige of journals with ranking score above a given threshold. Here we demonstrate that, between 1999 and 2009, there was high and increasing overall prestige of first quartile journals in only four areas of Scopus. Also, there was high and decreasing overall prestige of first quartile journals in five areas. Two subject areas showed high and oscillating overall prestige of first quartile journals. And there was low and increasing overall prestige in four areas, since the 1999.

When comparing permutations of these four classes of perspectives, there are up to 145 kinds of equality/inequality relations. From these numerous relations, we analyze the difference between the Matthew Effect and the Matthew Phenomenon. We provide a precise definition and point out that many previous empirical research studies on the Matthew Effect based on citations belong primarily to the Matthew Phenomenon, and not the true meaning of the Matthew Effect. Due to the difficulty in determining the Deserved Citations, the Matthew Effect is in itself difficult to measure, although it is commonly believed to influence citation counts. Furthermore, from the theoretical facts, we outline four new effects/phenomena: the Self-confidence Effect/Phenomenon, the Narcissus Effect/Phenomenon, the Other-confidence Effect/Phenomenon, and the Flattery Effect/Phenomenon, and we discuss additional influencing factors.

Our primary aim is to provide a better understanding of the ways in which emerging firms interact with, and learn from, technology diffusers. Two implications can be drawn from our analysis. Firstly, emerging firms within an emerging industry can enhance their technological capabilities through positive external learning activity. Secondly, despite the fact that technology diffusers have clear technological advantages, with the emergence of a new field, their influence within the network could potentially be decayed if they fail to remain proactive in terms of the absorption of available external knowledge.

The aim of this study was to use a surname-based bibliometric indicator to assess the representation of Jewish authors in US biomedical journals. The other aim was to test the hypothesis that the representation of Jewish authors in US biomedical journals corresponds to their representation among US Nobel Prize winners in Medicine, 1960-2009. From among articles published 1960- 2009 in all journals covered by Medline (> 5,000), and in the top 10 US biomedical journals we counted articles by authors from the following three groups: Kohenic-Levitic surnames, other common Jewish surnames, and the most frequent non-Jewish surnames in the USA. The frequency of a surname in the US population (1990 US Census) was used to calculate the expected number of scientific publications: the total number of published articles multiplied by a surname's frequency. The actual number of articles with that surname was also determined. The ratio of actual to expected number of articles was used as a measure of representation proportionality. It was found that the ratio of actual to expected number of articles in both Jewish groups is close to 10 among all (> 5,000) journals, and close to 20 in the top 10 journals. The ratio of actual to expected numbers of Jewish Nobel Laureates in the USA is also close to 20. In conclusion, the representation of Jewish authors in top 10 US biomedical journals corresponds to the representation of Jewish Nobel Laureates among US laureates. We hypothesize that disproportional representation of Jewish scientists as authors in top biomedical journals and among Nobel Prize laureates in Medicine is mostly due to their overrepresentation as research participants, not because of the increased chances for reward for a Jewish researcher per se.

Previous methods either profess ignorance about the seniority of co-authors (egalitarian weights) or are based in an ad hoc way on the order of authors (rank weights). Pareto weights are based on the respective citation records of the co-authors. Pareto weights are proportional to the probability of observing the number of citations obtained. Assuming a Pareto distribution, such weights can be computed with a simple, closed-form equation but require a few iterations and data on a scholar, her co-authors, and her co-authors' co-authors. The use of Pareto weights is illustrated with a group of prominent economists. In this case, Pareto weights are very different from rank weights. Pareto weights are more similar to egalitarian weights but can deviate up to a quarter in either direction (for reasons that are intuitive).

We combine these two ideas in a single indicator, referred to as the recursive mean normalized citation score indicator, and we study the validity of this indicator. Our empirical analysis shows that the proposed indicator is highly sensitive to the field classification scheme that is used. The indicator also has a strong tendency to reinforce biases caused by the classification scheme. Based on these observations, we advise against the use of indicators in which the idea of normalization based on a field classification scheme and the idea of recursive citation weighing are combined.

The goal is to highlight some weaknesses and clarify some "dark sides" in the conceptual framework of this analogy, discussing the formal validity and practical meaning of the concepts of Energy, Exergy and Entropy in bibliometrics. Specifically, this analogy highlights the following major criticalities: (1) the definitions of E and X are controversial, (2) the equivalence classes of E and X are questionable, (3) the parallel between the evolution of thermodynamic and bibliometric systems is forced, (4) X is a non-monotonic performance indicator, and (5) in bibliometrics the condition of "thermodynamic perfection" is questionable. Argument is supported by many analytical demonstrations and practical examples.

These methods have a quite global scope in citation analysis but were first applied to the journal impact, in the experimental Audience Factor (AF) and the Scopus Source- Normalized Impact per Paper (SNIP). Analyzing some properties of the Garfield's Journal Impact Factor, this note highlights the rationale of citing-side (or source-level, fractional citation, ex ante) normalization.

In those cases, fractional allocations are attributed to each co-author with a summation equal to one. These allocations are tailored on the basis of each author contribution. It is denoted "Tailor Based Allocations (TBA)" for multiple authorship. Several protocols to TBA are suggested. The choice of a specific TBA may vary from one discipline to another. In addition, TBA is applied to the number of citations of a multiple author paper to have also this number conserved. Each author gets only a specific fraction of the total number of citations according to its fractional paper allocation. The equivalent of the h-index obtained by using TBA is denoted the gh-index. It yields values which differ drastically from those given by the h-index. The gh-index departs also from (h) over bar recently proposed by Hirsh to account for multiple authorship. Contrary to the h-index, the gh-index is a function of the total number of citations of each paper. A highly cited paper allows a better allocation for all co-authors while a less cited paper contributes essentially to one or two of the co-authors. The scheme produces a substantial redistribution of the ranking of scientists in terms of quantitative records. A few illustrations are provided.

OCT 2011. p.381-396 SPRINGER, DORDRECHT SEARCH TERM(S): PRICE DJD rauth KEYWORDS: Collaboration networks; Community structure; Intra- and inter-institutional collaborations; Geographic distance; Research specialty KEYWORDS+: COMPLEX NETWORKS; SOCIAL NETWORK; SCIENCE; KNOWLEDGE; GEOGRAPHY; TEAMS ABSTRACT: This paper investigates the role of homophily and focus constraint in shaping collaborative scientific research. First, homophily structures collaboration when scientists adhere to a norm of exclusivity in selecting similar partners at a higher rate than dissimilar ones. Two dimensions on which similarity between scientists can be assessed are their research specialties and status positions. Second, focus constraint shapes collaboration when connections among scientists depend on opportunities for social contact. Constraint comes in two forms, depending on whether it originates in institutional or geographic space. Institutional constraint refers to the tendency of scientists to select collaborators within rather than across institutional boundaries. Geographic constraint is the principle that, when collaborations span different institutions, they are more likely to involve scientists that are geographically co-located than dispersed. To study homophily and focus constraint, the paper will argue in favour of an idea of collaboration that moves beyond formal co-authorship to include also other forms of informal intellectual exchange that do not translate into the publication of joint work. A community-detection algorithm for formalising this perspective will be proposed and applied to the co- authorship network of the scientists that submitted to the 2001 Research Assessment Exercise in Business and Management in the UK. While results only partially support research-based homophily, they indicate that scientists use status positions for discriminating between potential partners by selecting collaborators from institutions with a rating similar to their own. Strong support is provided in favour of institutional and geographic constraints. Scientists tend to forge intra- institutional collaborations; yet, when they seek collaborators outside their own institutions, they tend to select those who are in geographic proximity. The implications of this analysis for tie creation in joint scientific endeavours are discussed.

Three indicators are combined: sudden increases in the frequency of specific words; the number and speed by which new authors are attracted to an emerging research area, and changes in the interdisciplinarity of cited references. The mixed model is applied to four emerging research areas: RNAi, Nano, h-Index, and Impact Factor research using papers published in the Proceedings of the National Academy of Sciences of the United States of America (1982-2009) and in Scientometrics (1978-2009). Results are compared in terms of strengths and temporal dynamics. Results show that the indicators are indicative of emerging areas and they exhibit interesting temporal correlations: new authors enter the area first, then the interdisciplinarity of paper references increases, then word bursts occur. All workflows are reported in a manner that supports replication and extension by others.

OCT 2011. p.437-463 SPRINGER, DORDRECHT SEARCH TERM(S): MERTON RK rauth; PRICE DJD rauth; ZUCKERMAN H rauth; MERTON RK SCIENCE 159:56 1968 KEYWORDS: Simulation; Cumulative advantage; Landscape search; Science models; Science policy KEYWORDS+: CITATION DISTRIBUTION; RUGGED LANDSCAPES; NETWORKS; MODEL; OPTIMIZATION; STRATEGIES ABSTRACT: Agent-based simulation can model simple micro-level mechanisms capable of generating macro-level patterns, such as frequency distributions and network structures found in bibliometric data. Agent- based simulations of organisational learning have provided analogies for collective problem solving by boundedly rational agents employing heuristics. This paper brings these two areas together in one model of knowledge seeking through scientific publication. It describes a computer simulation in which academic papers are generated with authors, references, contents, and an extrinsic value, and must pass through peer review to become published. We demonstrate that the model can fit bibliometric data for a token journal, Research Policy. Different practices for generating authors and references produce different distributions of papers per author and citations per paper, including the scale-free distributions typical of cumulative advantage processes. We also demonstrate the model's ability to simulate collective learning or problem solving, for which we use Kauffman's NK fitness landscape. The model provides evidence that those practices leading to cumulative advantage in citations, that is, papers with many citations becoming even more cited, do not improve scientists' ability to find good solutions to scientific problems, compared to those practices that ignore past citations. By contrast, what does make a difference is referring only to publications that have successfully passed peer review. Citation practice is one of many issues that a simulation model of science can address when the data-rich literature on scientometrics is connected to the analogy- rich literature on organisations and heuristic search.

We describe the nature, characteristics, and use of USDA research based on scientometric indicators using patent analysis and three bibliometric methods: publication analysis, citation analysis, and science mapping. Our analyses are intended to be purely descriptive in nature. They demonstrate that USDA maintains several core scientific competencies and its research is much broader than and reaches well beyond traditional agricultural sciences for which it is best known. We illustrate the current status, recent trends, and clear benchmarks for planning and assessing future USDA research across an array of scientific disciplines.

However, its application in scientific evaluation is difficult due to the bi-dimensional character of the distribution. Some bibliometric indexes that try to synthesize in a numerical value the principal characteristics of this distribution have been proposed recently. In contrast with other bibliometric measures, the biases that the distribution tails provoke, are reduced by the h-index. However, some limitations in the discrimination among researchers with different publication habits are presented in this index. This index penalizes selective researchers, distinguished by the large number of citations received, as compared to large producers. In this work, two original sets of indexes, the central area indexes and the central interval indexes, that complement the h-index to include the central shape of the citation distribution, are proposed and compared.

SEP 2011. p.747-760 SPRINGER, DORDRECHT SEARCH TERM(S): SCIENTOMETRIC* item_title KEYWORDS: Scientometrics; Incentives; Research policy; Quasi experimental design; South Africa KEYWORDS+: ECONOMICS; PROGRAMS ABSTRACT: The influence of the National Research Foundation's (NRF) rating system on the productivity of the South African social science researchers is investigated scientometrically for the period from 1981 to 2006. Their output performance is mainly indicated by their research publications. Following international best practice in scientometrics as well as the behavioural reinforcement theory, we employed the "before/after control impact (BACI) method'', as well as the well known econometric breakpoint test as proposed by Chow. We use as control group the publications in the field of clinical medicine. The field is not supported by NRF and hence clinical medicine researchers are not affected by the evaluation and rating system. The findings show a positive impact of the NRF programme on the research outputs of social sciences researchers and the implementation of the programme has increased the relevant population of research articles by an average of 24.5% (during the first 5 years) over the expected number of publication without the programme. The results confirm the scientometric findings of other studies (e. g. that of Nederhof) that ratings promulgate research productivity.

This paper proposes a relative bidimensional index that takes into account both the net production and the quality of it, as an attempt to provide a comprehensive and objective way to compare the research output of different institutions in a specific field, using journal contributions and citations. The proposed index is then applied, as a case study, to rank the top Spanish universities in the fields of Chemistry and Computer Science in the period ranging from 2000 until 2009. A comparison with the top 50 universities in the ARWU rankings is also made, showing the proposed ranking is better suited to distinguish among non-elite universities.

These multiple view information allows us to find a better pattern as long as we integrate them in an appropriate way. So clustering by integrating multi-view representations that describe the same class of entities has become a crucial issue for knowledge discovering. We integrate multi-view data by a tensor model and present a hybrid clustering method based on Tucker-2 model, which can be regarded as an extension of spectral clustering. We apply our hybrid clustering method to scientific publication analysis by integrating citation-link and lexical content. Clustering experiments are conducted on a large-scale journal set retrieved from the Web of Science (WoS) database. Several relevant hybrid clustering methods are cross compared with our method. The analysis of clustering results demonstrate the effectiveness of the proposed algorithm. Furthermore, we provide a cognitive analysis of the clustering results as well as the visualization as a mapping of the journal set.

A comprehensive assessment covered overall performance, journals, subject categories, internationally collaborative countries, national inter-institutionally collaborative institutions, and most-cited papers in 22 scientific fields. China saw a strong growth in scientific publications in the last decade, to some extent due to increasing research and development expenditure. China has been more active in ESI fields of chemistry and physics, but more excellent in materials science, engineering and mathematics. Most publications were concerned with the common Science Citation Index subject categories of multidisciplinary chemistry, multidisciplinary materials and science, and physical chemistry. About one half China's ESC papers were internationally collaborative and the eight major industrialized countries (the USA, Germany, the UK, Japan, France, Canada, Russia, and Italy) played a prominent role in scientific collaboration with China, especially the USA. The Chinese Academy of Sciences took the leading position of institutions with many branches. The "985 Project'' stimulated the most productive institutions for academic research with a huge funding injection and the universities in Hong Kong showed good scientific performance. The citation impact of internationally collaborative papers differed among fields and international collaborations made positive contributions to academic research in China.

SEP 2011. p.885-898 SPRINGER, DORDRECHT SEARCH TERM(S): HIRSCH JE P NATL ACAD SCI USA 102:16569 2005 KEYWORDS: Academic inbreeding; Scientific effectiveness; Turkish universities KEYWORDS+: H-INDEX ABSTRACT: In academia, the term "inbreeding'' refers to a situation wherein PhDs are employed in the very same institution that trained them during their doctoral studies. Academic inbreeding has a negative perception on the account that it damages both scientific effectiveness and productivity. In this article, the effect of inbreeding on scientific effectiveness is investigated through a case study. This problem is addressed by utilizing Hirsch index as a reliable metric of an academic's scientific productivity. Utilizing the dataset, constructed with academic performance indicators of individuals from the Mechanical and Aeronautical Engineering Departments, of the Turkish Technical Universities, we demonstrate that academic inbreeding has a negative impact on apparent scientific effectiveness through a negative binomial model. This model appears to be the most suitable one for the dataset which is a type of count data. We report chi-square statistics and likelihood ratio test for the parameter alpha. According to the chi- square statistics the model is significant as a whole. The incidence rate ratio for the variable "inbreeding'' is estimated to be 0.11 and this ratio tells that, holding all the other factors constant, for the inbred faculty, the h-index is about 89% lower when compared to the non-inbred faculty. Furthermore, there exists negative and statistically significant correlation with an individual's productivity and the percentage of inbred faculty members at the very same department. Excessive practice of inbreeding adversely affects the overall productivity. Decision makers are urged to limit this practice to a minimum in order to foster a vibrant research environment. Furthermore, it is also found that scientific productivity of an individual decreases towards the end of his scientific career.

The paper categorizes the journals into four main categories (A- D) based on their efficiency levels. The results are then compared to the 27 "core economic journals'' as introduced by Diamond (Curr Contents 21(1):4-11, 1989). The results reveal that after more than 20 years Diamonds' list of "core economic journals'' is still valid. Finally, for the first time the paper uses data from four well-known databases (SSCI, Scopus, RePEc, Econlit) and two quality ranking reports (Kiel Institute internals ranking and ABS quality ranking report) in a DEA setting and in order to derive the ranking of 229 economic journals.

Waltman (Scientometrics 87:467-481, 2011a) argue that this change does not affect rankings at various aggregated levels. However, CWTS data is not publicly available for testing and criticism. Therefore, we comment by using previously published data of Van Raan (Scientometrics 67(3):491-502, 2006) to address the pivotal issue of how the results of citation analysis correlate with the results of peer review. A quality parameter based on peer review was neither significantly correlated with the two parameters developed by the CWTS in the past citations per paper/mean journal citation score (CPP/JCSm) or CPP/FCSm (citations per paper/mean field citation score) nor with the more recently proposed h-index (Hirsch, Proc Natl Acad Sci USA 102(46):16569-16572, 2005). Given the high correlations between the old and new "crown'' indicators, one can expect that the lack of correlation with the peer-review based quality indicator applies equally to the newly developed ones.

We point out that Opthof and Leydesdorff draw their conclusions based on a very limited amount of data. We also criticize the statistical methodology used by Opthof and Leydesdorff. Using a larger amount of data and a more appropriate statistical methodology, we do find a significant correlation between the CPP/FCSm indicator and peer judgment.

A new wave of the discussion rose after the publication of the Thomson Reuters Report, which stated a decrease in Russia's contribution to the world information flow. These problems were addressed in part in the article "Russia Must Become a Scientific Superpower" by RAS Corresponding Member S.M. Rogov (Her. Russ. Acad. Sci. 80, 313 (2010)). The assessment of scientific activity, the attitude to which in the scientific community is controversial, is discussed in the article published below. - -------------------------------------------------------------------------- TITLE: Universal Citation and the American Association of Law Libraries: A White Paper (Article, English) AUTHOR: Kauger, Y; Billings, C; Carlson, K; Cannan, J; Kauger, Y SOURCE: LAW LIBRARY JOURNAL 103 (3).

This paper aims to investigate whether this validation is possible using the number of Nobel Prize awards. Design/methodology/approach - This study uses several analytical treatments of the data to investigate: whether Nobel Prize awards are sporadic events or they depend on the scientific activity of countries or institutions and can be used in research evaluation; and the association between the number of Nobel Prize achievements and conventional bibliometric indicators across countries and institutions. Findings - This study finds that conventional bibliometric indicators, numbers of publications, citations, and top 1 per cent most cited publications, correlate with the number of Nobel Prize achievements in several advanced countries with similar research abilities. Contrarily, in countries and institutions with more variable research characteristics, there is no association between conventional bibliometric indicators and the number of Nobel Prize achievements, and their use as indicators of research excellence is not valid. In contrast, the number of national articles in Nature and Science correlates with the number of Nobel Prize achievements across countries and institutions. Practical implications - Science administrators implementing research evaluations and research incentives based on conventional bibliometric indicators should consider that increasing the scores of these indicators does not imply an improvement in research excellence. Originality/value - The study demonstrates that Nobel Prize achievements are not singular events that occur by chance. Therefore, the number of Nobel Prize achievements can be used to validate bibliometric indicators.

Notable in determining research quality is the publication of research papers in journals with a high ranking within the Institute for Scientific Information (ISI) or Excellence in Research for Australia (ERA). This paper reports an analysis of Australian nurse researcher output in journals highly ranked by the ISI and ERA. Research abstracts were analysed for topic, sources of data, location of research and methodological paradigm. A total of 530 articles from five Australian and from five USA and UK journals were analysed. There was an increase in output from the period of prior analyses in 2000. Practice issues are the most common topic followed closely by nurse education. While most studies used nurses as sources of data there were more studies in which consumers of nursing care were the point of inquiry. Both qualitative and quantitative methods were utilised. Given the importance of rationalising nursing practice and adding new knowledge to evidence based care, it is imperative for the nursing profession to disseminate research findings. Failure to do this may result in poor return in investment outcomes for the future of nursing in Australia and internationally.

Triple-Helix Relations among Technology, Organization, and Geography ?ivind Strand and Loet Leydesdorff Using entropy statistics and data for all (0.5 million) Norwegian firms, the national and regional innovation systems are decomposed into three subdynamics: (i) economic wealth generation, (ii) technological novelty production, and (iii) government interventions and administrative control. The mutual information in three dimensions can then be used as an indicator of potential synergy, that is, reduction of uncertainty. We aggregate the data at the NUTS3 level for 19 counties, the NUTS2 level for seven regions, and the single NUTS1 level for the nation. 19.6% of the synergy (measured as in-between group reduction of uncertainty) was found at the regional level, whereas only another 2.7% was added by aggregation at the national level of integration. Using this triple-helix indicator, the counties along the west coast are indicated as more knowledge-based than the metropolitan area of Oslo or the geographical environment of the Technical University in Trondheim. Foreign direct investment seems to have larger knowledge spill-overs in Norway (oil, gas, offshore, chemistry, and marine) than the institutional knowledge infrastructure in established universities. The northern part of the country, which receives large government subsidies, shows a deviant pattern that is not stable across scale-levels of aggregation http://arxiv.org/ftp/arxiv/papers/1109/1109.6597.pdf _____ Has Globalization Strengthened South Korea ?s National Research System? National and International Dynamics of the Triple Helix of Scientific Co-authorship Relationships in South Korea Scientometrics (in press; doi: 10.1007/s11192-11011-10512-11199) Ki-Seok Kwon, Han Woo Park, Minho So, and Loet Leydesdorff We trace the structural patterns of co-authorship between Korean researchers at three institutional types (University, Government, and Industry) and their international partners in terms of the mutual information generated in these relations. Data were collected from the Web of Science during the period 1968-2009. The traditional Triple-Helix indicator was modified to measure the evolving network of co-authorship relations.. The results show that international co-authorship relations have varied considerably over time and with changes in government policies, but most relations have become stable since the early 2000s. In other words, the national publication system of Korea has gained some synergy from R&D internationalization during the 1990s, but the development seems to stagnate particularly at the national level: whereas both university and industrial collaborations are internationalized, the cross-connection within Korea has steadily eroded. http://www.springerlink.com/content/g174741358324147/fulltext.html http://www.leydesdorff.net/koreath.11/koreath.11.pdf (preprint version) _____ Sociological and Communication-Theoretical Perspectives on the Commercialization of the Sciences Both self-organization and organization are important for the further development of the sciences: the two dynamics condition and enable each other. Commercial and public considerations can interact and "interpenetrate" in historical organization; different codes of communication are then "recombined." However, self-organization in the symbolically generalized codes of communication can be expected to operate at the global level. The Triple Helix model allows for both a neo-institutional appreciation in terms of historical networks of university-industry-government relations and a neo-evolutionary interpretation in terms of three functions: (i) novelty production, (i) wealth generation, and (iii) political control. Using this model, one can appreciate both subdynamics. The mutual information in three dimensions enables us to measure the trade-off between organization and self-organization as a possible synergy. The question of optimization between commercial and public interests in the different sciences can thus be made empirical. http://arxiv.org/ftp/arxiv/papers/1109/1109.6600.pdf _____ ** apologies for cross-postings Loet Leydesdorff Professor, University of Amsterdam Amsterdam School of Communications Research (ASCoR) Kloveniersburgwal 48, 1012 CX Amsterdam.

We analysed the publications, citations, citations per publication and h- index from 1996 to date using the Scopus (R) database for 1630 (1120 men, 510 women) for faculty members from 24 randomly selected US academic anaesthesiology departments The median (interquartile range [range]) h- index of US academic anaesthesiologists was 1 [0-5 (0-44)] with 3 [0-18 (0-398)] total publications, 24 [0-187 (0-8515)] total citations, and 5 [0-14 (0-252)] citations per publication. Faculty members in departments with National Institutes of Health funding were more productive than colleagues in departments with little or no government funding. The h- index increased significantly between successive academic ranks concomitant with increases in the number of publications and total citations. Men had higher median h-index than women concomitant with more publications and citations, but the number of citations per publication was similar between groups. Our results suggest that h-index is a reasonable indicator of scholarly productivity in anaesthesia. The results may help comparisons of academic productivity across countries and may be used to assess whether new initiatives designed to reverse recent declines in academic anaesthetic are working.

Cluster analysis, with its seemingly limitless power to produce groupings in any dataset, has all the trappings of a super-technique. However, the method produces clusters even in the absence of any natural structure in the data, and has no statistical basis to reject the null hypothesis that there are no natural groupings in the data. Application of cluster analysis, therefore, presupposes sound researcher judgment and responsible analysis and reporting. This paper summarizes the results of a reflective review of the application of cluster analysis in Information Systems (IS) research published in major IS outlets. Based on the analysis of 55 IS applications of cluster analysis, various deficiencies noticed in its use are discussed along with suggestions for future practice. By analyzing the results over two time periods, longitudinal trends in the application of this technique are highlighted.
