SCHWEIM : E-Mail: schweim at dimdi.de TITLE : Biomedical databases and the journal impact factor AUTHOR: Winkmann G, Schweim HG JOURNAL DEUTSCHE MEDIZINISCHE WOCHENSCHRIFT 125: (38) 1133-1141 SEP 22 2000 Document type: Article Language: German Cited References: 58 Times Cited: 1 Abstract: Background: Citation frequencies of medical journals are measured by the Journal Impact Factors (IF) published annually in the Journal Citation Report (JCR). Conclusions drawn from IF concerning the distribution of single journal articles are used worldwide for academic evaluation purposes. Because of this importance, IF are widely and controversially discussed, also regarding their derivation from a limited pool of databases (Science Citation Index, SCI). Objective: To determine the comprehensiveness of IF's data basis by testing (i) SCI's sources, (ii) SCI's output. Are the IF sufficient for an objective evaluation of medical journals. Methods: Comparative searches in 38 databases and their combinations (SCI; MEDLINE [ME]; EMBASE [EM]; BIOSIS Previews [BA] and other relevant systems). Results: (i) Journals with higher IF (greater than or equal to 1)are almost completely retrievable in SCI (98%), but only approx. 60% in ME, EM, BA. (ii) Reverse: three samples of mainly German-language journals frequently indexed in SCI were represented in JCR by 90%; but only 23,5-57% of sample periodicals had an IF when indexed in ME, EM and BA, but not in SCI. (iii) Compiled average search results in the mast productive databases in 18 biomedical queries, when titles were searched: SCI=34%, ME=27%, EM=33%, BA=25%; and, when combined: SCI + ME=44%, SCI i ME i EM=55%, SCI i ME + EM i BA=65%, compared to the results in a 38-databases cluster. Costs increase in the order ME < EM < SCI < BA < Derwent, GAS. Conclusions: (i) The citation analyses presented in JCRs appear limited especially regarding German-language biomedical journals. Evaluation of publications based on IF therefore should be complemented by corrective measures. (ii) Single-database searches, including SCI, at best render orientating results; database combinations are recommended when higher completeness is required.

A Bibliometric Analysis - A Summary Ronnie Lidor and Uri Miller Statistical reports on aging populations reveal that over the past 3 decades the number of older people (60 years of age and over) has rapidly grown. For example, from 1960 to 1990 the number of older people in European communities rose from 46.5 million to 68.6 million. It is predicted that in 2020 the aging trend will be even stronger; the percentage of the population aged 60 and over will be 25.3 in the United Kingdom, 29.9 in Italy, 27.7 in Germany, and 28.9 in Belgium. This trend can be observed not only in Europe but also in the United States and other parts of the world. It has been reported that since the late 1980s the United States has the highest proportion of elderly. Although in developing countries such as Ethiopia, India, Burma, and Bangladesh the trend is not as strong as in Europe and the United States, the percentage of the population over age 60 in these countries has also grown over the past 2 decades. It was the purpose of this study to examine the state of interest of researchers in the exercise and sport sciences on aging, the older adult population, and physical activity. More specifically, we analyzed the number of publications - journal articles on aging and physical activity - that are included for the last 3 decades in the SPORT Discus and MEDLINE databases. It was assumed that (a) the ratio has increased between the number of publications on adult populations and the total number of publications in SPORT Discus and MEDLINE. (b) the number of publications that focus on aging and physical activity has increased, and (c) the expected increased ratio would be observed in scientific periodicals from the behavioral sciences, as well as the medical and the physiological sciences. To study these assumptions, a bibliometric analysis was conducted on the SPORT Discus and MEDLINE databases. A bibliometric analysis has been defined as the application of mathematical and statistical methods to the study of bodies of writings - for example, scientific periodicals - to reveal the historical development of subject fields and patterns of authorship and publication. This type of analysis is widely used in the literature, mainly to provide a picture of the state of research in a discipline, as well as to determine broad characteristics of material currently in print. Our findings indicate that few changes have occurred during the last 3 decades with regard to the volume of publication on aging and physical activity. Two conclusions can be reached: (a) the interest of researchers in exercise and sport sciences does not reflect that of society at large concerning older adults, and (b) an in-depth analysis should be conducted to study the periodicals that are published not only in the area of exercise and sport sciences but also in other related areas such as medicine, psychology, and health.

MetroHealth Medical Center, Case Western Reserve University School of Medicine, Cleveland, Ohio. ________________________________ Purpose: To examine changes in subject contents and study designs, as well as impact on other journals, of research articles published in the Journal of Adolescent Health since its inception. Methods: A retrospective review of all research articles was conducted from selected years ranging from 1980 through 1998. The study sample comprised the following: Original Articles, Case Reports, Brief Scientific Reports, International Articles, Fellowship Forum and Health Briefs. Results: A total of 582 articles were evaluated. The total percentage of medical topics in research articles published in the journal decreased from 61% in 1980-1981 to 36% in 1997-1998 (p<0.01). For example, topics related to physical growth and development dropped from 9% of all research articles in 1980-1981 to 1% in 1997-1998, and contents related to acute or chronic medical conditions dropped from 15% to 5% over the same period of time. These findings were in contrast to topics related to psychosocial issues, which increased from 23% to 50% (p<0.01) over the same period of time. This increase was largely accounted for by studies focusing on high-risk behavior. Retrospective designs, including case reports/series and chart reviews, decreased from 26% of all research articles in 1980-1981 to 9% in 1997-1998 (p<0.01). The percentage of observational studies, i.e., those utilizing cross-sectional and longitudinal designs, increased from 62% to 79% over the same period of time (p<0.01). No changes were observed in the percentage of experimental designs, never exceeding >5% of total study designs. The number of citations per year, i.e., articles from the journal cited in other scientific journals over the following two years, continued to increase (55 in 1987, 92 in 1992, 206 in 1996) with the total cumulative sum of citations being 1274 (1997 data). Conclusion: In the Journal of Adolescent Health, a shift in subject content of research articles from medical to psychosocial topics was observed over the past two decades. A shift in research designs from retrospective to observational was observed over the same period of time. Citations in other joumals increased over the lifetime of this journal. ------------------------------------------------------------- (c) ISI, Reprinted with permission Please visit their website at www.isinet.com ------------------------------------------------------------- From gwhitney at UTK.EDU Wed Mar 7 18:15:54 2001 From: gwhitney at UTK.EDU (Gretchen Whitney) Date: Wed, 7 Mar 2001 18:15:54 -0500 Subject: ABS: Critchfield, Sources cited most frequently in the experimental analysis of human behavior Message-ID: Thomas S.

Email: chaomei.chen at brunel.ac.uk, ray.paul at brunel.ac.uk To make knowledge visualizations clear and easy to interpret, the authors have developed a method that extends and transforms traditional author co-citation analysis (ACA) by extracting structural patterns from the scientific literature and representing them in a 3D knowledge landscape. Integrating citation and co-citation patterns provides a rich, ecological representation of a knowledge domain. Users can apply visualizations to discover patterns and make valuable connections among data. The authors' approach extends conventional ACA by integrating structured modeling and information visualization techniques to provide a 3D knowledge landscape based on citation patterns. Their four-step procedure introduces Pathfinder network scaling to replace multidimensional scaling. It also integrates Pathfinder and factor analysis to visualize specialties in the underlying domain knowledge and visualizes the citation frequency of scientists to track changes in their influence over time. This knowledge visualization approach identifies intellectual groupings based on extending the traditional ACA, augmenting the existing document- and concept-centered approaches to knowledge visualization. The 3D knowledge landscape has practical implications in knowledge visualization, digital libraries, domain analysis, and subject domains, providing powerful tools for tracking intuitively scientific knowledge.

From this viewpoint, there is no need to examine the institutional context of academic departments because distinction is viewed as a matter of merit rather than affiliation. Juxtaposed to this perspective, the present inquiry, based on data from three comparable national studies of research doctorate programs, presents evidence that the ratings reflect a contextual property representative of the university and not various performance-based departmental attributes. In effect, academic departments within universities are found to be quite similar to one another with respect to external raters' perceptions of their "quality." The importance of this finding rests not with the relative ranking of departments or universities to one another but in the discovery that departmental status operates primarily within a stable institutional context. Administrative policy implications of these findings, which are relevant to both faculty leaders and institutional decision makers, are discussed in light of current perspectives on the use of departmental ratings.

Methods: All articles published in the four major otolaryngology journals in each of the years 1978, 1988, and 1998 were reviewed The authorship panel of each article was examined for number of authors, gender, educational degree category, and subspecialty area of publication. Data were analyzed for trends in female authorship and the association of gender with the other design variables. Results: A total of 2,463 articles were analyzed. The average percentage of female authorship increased from 4.1% in 1978 to 8.7% in 1988 and 12.4% in 1998, and the percentage of articles with a female "first author" increased from 3.2% to 7.4% and 11.4% for the same years, respectively. Each of these increases was statistically significant (P <.001). The weighted rank of female authorship also increased from 0.063 to 0.164 and 0.243 for the same years, respectively (P <.001). With respect to subspecialty publication, women were first authors of 14.7% of articles concerning pediatric otolaryngology but accounted for 9.9% or less of the first authors in the other subspecialty areas (P <.001). Female authors were also much more likely to be nonphysicians (P <.001) than men. Conclusions: There has been a significant trend toward increased female authorship in the otolaryngology literature. A significant portion of this is accounted for by nonphysician female authors, and female authorship tends to be concentrated in pediatric otolaryngology.

Paper 1 http://www.cindoc.csic.es/cybermetrics/articles/v5i1p1.html m.thelwall at wlv.ac.uk Abstract Search engines are an important tool for information foraging on the web. The broad details of how they work is, therefore, of relevance to both information seekers and providers. Yet search engines are known to only index a fraction of the web, up to a maximum of 16% in one recent study. A search engine must crawl the web periodically in order to maintain an up to date index, but, given the limitations of total coverage, how can it decide which sites to cover and which to ignore? One answer lies in research showing the importance of web links in identifying useful sources of information. This paper reports on an experiment to investigate the effect of link count on the indexing of 1000 sites in three search portals over a period of seven months. It was found that, although all engines added sites during the period of the survey, only Google showed evidence of being very responsive to the existence of links on the test site, whereas AltaVista's results were very stable over time. *** Loet Leydesdorff, Loet (2001). Indicators of Innovation in a Knowledge-based Economy. Cybermetrics, 5 (issue 1). Paper 2 http://www.cindoc.csic.es/cybermetrics/articles/v5i1p2.html loet at leydesdorff.net Abstract The concept of 'modes of knowledge production' was used by Gibbons et al. (1994) to distinguish between transdisciplinary ('Mode 2') R&D and more traditional ('Mode 1') research. This paper explores whether the Internet provides a means to operationalize 'Mode 2' knowledge production as containing a differently codified communication pattern which can be compared to co-word and citation patterns in scientometric databases ('Mode 1'). Innovations on the drugs market, for example, can be indicated at the commercial end by using the trade names of the drugs (e.g., Evista), while the very same innovation can be retrieved in the patent and science citation databases using the generic names of the active substances involved (in this case, raloxifene). By using the generic names the new drugs can be traced back into their respective knowledge bases. -- ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Isidro F.

A search strategy based on Medical Subject Headings for dental implants was developed to examine MEDLINE using the Ovid Web Gateway search engine. Sensitive and specific methodologic search filters identified 4 categories of information: etiology, diagnosis, therapy, and prognosis. The results were then subdivided by year to identify trends and sorted to identify the sources of publications. The searches identified 4,655 articles published in English between 1989 and 1999 on human dental implants on MEDLINE, The mean number of articles (+/- SD) per year ranged from 15 +/- 11 for specific searches to 107 +/- 50 for sensitive searches. The number of articles increased by 14% to 43% each year for the sensitive search. When subdivided by clinical category, the mean numbers of articles per year for sensitive and specific searches were, respectively: diagnosis 12 +/- 7.5 and 1.5 +/- 1.6, etiology 58 +/- 33 and 1.9 +/- 2.5, therapy 23 +/- 15 and 0.3 +/- 0.5 and prognosis 67 +/- 33 and 12 +/- 8.3. Four dental journals account for approximately half of these publications. These results provide 6 key central findings: (1) there appears to be a substantial literature of clinically relevant information on implants upon which to base clinical decisions; (2) the implant literature is significantly biased toward articles addressing prognosis; (3) to stay current, one would need to read between 1 and 2 articles per week 52 weeks per year, and this number increases significantly each year; (4) approximately 50% of the articles were published in 4 journals, whereas the remainder reside in approximately 97 other journals, making it difficult to stay current; (5) these trends reaffirm the need for lifelong learning; (6) these trends also suggest the need for computer-based clinical knowledge systems.

However, little is known to what extent industries participate in scientific research, what their contribution is to knowledge production. Against the background of the contemporary global changes that are taking place in knowledge production, an attempt is made to capture the changing pattern of industrial scientific research activities in Sweden. Like many other countries Sweden is changing its pattern of conducting research. Private firms are being increasingly integrated into national and international academic networks and collaborate with a variety of players. Cooperation and networking are proving to be ideal forms of scientific production for firms. We show that knowledge production is to a decreasing extent a self-contained activity in Sweden, and that through scientific co-authorships firms, primarily foreign firms, are becoming important players in Swedish industrial scientific research.

What is the collaborative situation like? Why do scientists collaborate? This study focuses on the micro level of research collaboration and investigates the reasons for and effects of collaboration for the individual scientist through a survey and a number of interviews. The interaction within the research team is highlighted, showing the feelings and conditions which encompass the teamwork. The empirical findings are conceptualized in a model where research collaboration is suggested to be understood as dependent on how the reasons, forms and effects respectively vary. The collaborations are characterized by strong pragmatism and a high degree of self-organization. Finally, the science policy implications of this study are discussed.It is suggested that research policy should provide financial and organizational possibilities for the researchers to establish joint ventures and also fund projects on a team or network basis.

Using data on articles about celestial masers, an astrophysics research area, logistic regressions with robust standard errors examine the extent to which characteristics of both potentially citing and potentially cited papers influence the probability that a citation exists between the papers. The results identify significant positive, effects of cited article cognitive content and cited article quality, providing support for a normative interpretation of the allocation of citations in which citations reflect payment of intellectual debt. In contrast, indicators of an author's position within the stratification structure of science fail to significantly improve the fit of the model, and thus provide no support for the social constructivist claim that citations are rhetorical tools of persuasion. Furthermore, the lack of effects of social ties between citing and cited authors provides little support for the argument that authors who know one another are more likely to cite one another's work. Overall, these results suggest that authors are likely to cite those articles most relevant to their work in terms of intellectual content, and seem little concerned with the characteristics of authors who write them.

The study is based on the methodology for online citation analysis developed by the Centre for Informetric Studies in Copenhagen, to facilitate a deeper understanding of journal evaluation procedures and, consequently, the evaluation of the research published in it. Highlighted features are: Libri as represented in the databases; authorship characteristics; users of the journal; export of knowledge; citation pattern; synchrone and diachrone analysis of the citation impact; citation half life; top ten most cited Libri articles; special issues published in the 1990s. The aim of the presented metric analyses is not only to provide a historical overview of the visibility and impact of an independent, international journal, but also to show an advanced method for journal evaluation and to promote the use of online citation analysis. Data presented in the 15 figures provide useful information about some properties of a scientific journal, which until now have not been highlighted in the form of scientific investigations analysing the importance and influence of a journal in a given field.

Authorship proliferation in neurosurgical research Message-ID: Author's E-mail : J.T. King, Jr. : jtk1 at pitt.edu TITLE : How many neurosurgeons does it take to write a research article? Authorship proliferation in neurosurgical research AUTHOR King JT JOURNAL NEUROSURGERY 47: (2) 435-440 AUG 2000 Document type: Article Language: English Cited References: 40 Times Cited: 0 Abstract: OBJECTIVE: Authorship proliferation in biomedical research has become rampant; the proportion of single-author articles is decreasing, the percentage of multiauthor articles is increasing, and the number of authors per publication is increasing. To determine whether authorship trends in the North American neurosurgical literature parallel trends observed in other areas of the biomedical literature, I studied original neurosurgical research articles published in the past 50 years. METHODS: I sampled clinical, anatomic, and laboratory investigations in Neurosurgery and the Journal of Neurosurgery at 10-year intervals from 1945 to 1995. For each research article, I determined the number of authors, the countries of origin, and the educational degrees of the authors. RESULTS: The mean number of authors per article has increased steadily in the past 50 years, from 1.8 (standard deviation, +/-0.8) authors per article in 1945 to 4.6 (standard deviation, +/-2.1) authors in 1995. The proportion of single-author articles is decreasing; these articles accounted for 43% of articles in 1945 and only 3% of articles in 1995. Increases in the proportions of non-M.D. authors and of articles originating outside the United States were also observed. CONCLUSION: The proliferation of multiauthor articles and the decrease in the proportion of single-author articles in the neurosurgical literature parallel trends observed in many other areas of biomedical research. Possible explanations include larger research teams, variable or absent journal criteria for defining authorship, and the increased awarding of "gift" authorships.

Kronick : e-mail: dkronick at satx.rr.com TITLE : The commerce of letters: Networks and "invisible colleges" in seventeenth- and eighteenth-century Europe AUTHOR Kronick DA JOURNAL LIBRARY QUARTERLY 71 (1): 28-43 JAN 2001 Document type: Article Language: English Cited References: 62 Times Cited: 0 Abstract: The "erudite letters" of early modern science had their antecedents in classical literature, The letters were not always concerned with scholarly matters but bear witness to the intellectual currents of the period in which they were written. Letters were circulated as a prepublication means of sharing and assessing ideas before they were put into print and also served as a medium of publication. The establishment of scientific societies and journals, rather than diminishing the flow of letters, served to stimulate and enhance their use. The commerce of letters also sustained what seventeenth-century scholars caned "invisible colleges." The concepts of networks and invisible colleges have been applied to modern scientific communication, where research techniques such as "co-citation analysis" have been used to reveal coteries with communal research interests. A study of early modern correspondence networks may suggest an analytical approach to scholarly correspondence that is capable of revealing additional networks or invisible colleges in the seventeenth and eighteenth centuries.

Message-ID: TITLE Are international journals of human geography really international? AUTHOR Gutierrez J, Lopez-Nieva P JOURNAL PROGRESS IN HUMAN GEOGRAPHY 25 (1): 53-69 MAR 2001 Document type: Article Language: English Cited References: 9 Times Cited: 0 Abstract: The aim of this article is to research the extent to which 'international journals' of human geography are really international. The analysis is based on the affiliation data (work centre) of the authors of articles and of members of editorial boards of a group of international journals; the results so obtained are related to the impact factors of these journals. The indicators used show that human geography journals in general have still not attained a high degree of internationalization. This may be interpreted as a sign of fragmentation within the discipline: human geographers do not constitute a proper international scientific community or, rather, a global community that makes use of certain common media of expression (international journals) but are fragmented into national or regional (linguistic) communities.

Of course, it's simple to find out when the books were published, but the out of print date information has proved illusive. One option is to go through the yearly retrospective Books in Print editions and note the year at which the individual titles ceased to be listed, although this would be a very labor intensive process. Does anyone know of a print or electronic resource that includes this information? The titles the faculty member needs to research are from the last 30 years or so.

We examine this literature via two expert perspectives: that of the author, who identified significant work by citing it (journal cocitation analysis), and that of the professional indexer, who tags published work with subject terms to facilitate retrieval from a bibliographic database (subject profile analysis). The data sources are SCISEARCH (the on-line version of Science Citation Index), and INSPEC (a database covering software engineering, computer science, and information systems), We use data visualization tools (cluster analysis, multidimensional scaling, and PFNets) to show the "intellectual maps" of software engineering. Cocitation and subject profile analyses demonstrate that software engineering is a distinct interdisciplinary field, valuing practical and applied aspects, and spanning a subject continuum from "programming-in-the-small" to "programming-in-the-large." This continuum mirrors the software development life cycle by taking the operating system or major application from initial programming through project management, implementation, and maintenance, Object orientation is an integral but distinct subject area in software engineering. Key differences are the importance of management and programming: (1) cocitation analysis emphasizes project management and systems development; (2) programming techniques/languages are more influential in subject profiles; (3) cocitation profiles place object-oriented journals separately and centrally while the subject profile analysis locates these journals with the programming/languages group.

Willett p.willett at sheffield.ac.uk TITLE Webometric analysis of departments of librarianship and information science AUTHOR Thomas O, Willett P JOURNAL JOURNAL OF INFORMATION SCIENCE 26 (6): 421-428 2000 Document type: Article Language: English Cited References: 26 Times Cited: 0 Abstract: This paper describes a webometric analysis of the linkages (or 'sitations') to websites associated with departments of librarianship and information science (LIS). Some of the observed sitation counts appear counter-intuitive and there is only a very limited correlation with peer evaluations of research performance, with many of the sitations being from pages that are far removed in subject matter from LIS. Our conclusions are that sitation data are not well suited to the quantitative evaluation of the research status of LIS departments and that departments can best boost their web visibility by hosting as wide a range of types of material as possible.
