The coverage of such papers by bibliographical data bases was evaluated. A list of frequently cited papers is given and discussed. Publications on physiology, biochemistry, genetics and diseases are cited most. Technical papers are rarely cited. A citation analysis is a useful tool in the evaluation of the scientific quality of research groups and individuals. For the evaluation of applied and technical research other tools should be developed / used.

This number now totals 7000 and is doubling every 11 years. The annual rate of publication per author and number of authors per paper in climate change science, 1.75 and 2.5 respectively, were similar to those for scientific publications in general but, based on the U.S. data, the cost per publishing scientist is very high largely because of the sums allocated to satellite programs related to climate change research. The total global cost of current climate change research is estimated at three billion U.S. dollars annually. Two plausible but very different interpretations of the growth curve of climate change research are presented and used to discuss its future. The importance of extra-scientific factors in controlling the growth of climate change studies is emphasized, limiting the predictive value of the scientometric analysis presented.

We posit that the probability of adopting a list of formal rankings is related to a set of characteristics of the department. Few schools have formal lists of journals. Our empirical findings imply that the probability of adopting a list is positively correlated with department size and is inversely correlated with the perceived quality of the department Considerable variation exists across such lists and across different institutions in the perceptions of the quality of journals. This suggests that, although lists may reduce the level of uncertainty regarding the assessment of research quality by providing explicit targets, lists may also induce faculty members to develop institution-specific human capital. This could reduce faculty mobility and impede career development. (C) 2000 Elsevier Science Inc. All rights reserved.

This is a first step toward developing online decision analysis systems. A search strategy based on Medical Subject Headings (MeSH) for orthodontics was developed to examine MEDLINE using the Ovid Web Gateway search engine. Sensitive and specific methodologic search filters were then employed to identify the 4 categories of information. The results were then subdivided by year to identify trends and sorted to identify source of publications, In the period 1990 to 1998, the MEDLINE searches identified 6938 English-language articles about orthodontics. The mean number of articles (+/-SD) per year ranged from 42 +/- 25 for specific searches to 314 +/- 214 for sensitive searches. The number of articles identified by the specific or sensitive searches increased 14% to 21% annually. When subdivided by clinical category, the mean numbers of articles per year for specific and sensitive searches were respectively: etiology 19 +/- 15 and 91 +/- 37, diagnosis 11 +/- 5 and 80 +/- 35, therapy 3 +/- 1 and 50 +/- 23, and prognosis 10 +/- 7 and 93 +/- 33. Five dental journals accounted for nearly half of these publications. These results provide several key findings: (1) there is a substantial literature of clinically relevant information in orthodontics upon which to base clinical decisions; (2) the information appears to be balanced between etiology, diagnosis, treatment, and prognosis; (3) approximately 45% of the articles reside in 5 journals, whereas the remainder reside in approximately 66 other journals, making it difficult to stay current; (4) the number of articles is increasing significantly each year; (5) to stay current, one would need to read between 1 and 6 articles per week, 52 weeks per year; (6) these trends suggest the need fur computer-based clinical knowledge systems; and (7) the methods used here can be immediately employed to identify the best and most current clinical orthodontic evidence.

Patients and methods Questionnaires about Internet use were completed by 180 patients attending a general urological outpatient clinic and by 143 patients attending a prostate cancer outpatient clinic, The Internet evaluation was conducted by reviewing 50 websites listed by the Hotbot(TM) search engine for two urological topics, prostate cancer and testicular cancer, and recording details such as authorship, information content, references and information scores, Results Of the patients actively seeking further information about their health, 19% of the general urological outpatient group and 24% of the prostate cancer group used the Internet to obtain this information. Most websites were either academic or biomedical (62%), provided conventional information (95%), and were not referenced (71%). The information score (range 10-100) was 44.3 for testicular cancer and 50.7 for prostate cancer: the difference in scores was not significant. Conclusion The use of the Internet by patients is increasing, with >20% of urology patients using the Internet to obtain further information about their health. Most Internet websites for urological topics provide conventional and good quality information. Urologists should be aware of the need to familiarize themselves with urological websites. Patients can then be directed to high-quality sites to allow them to educate themselves and to help them avoid misleading or unconventional websites.

The 1998 edition of Social Sciences Journal Citation Reports (JCR) - released in Fall 1999 - ranks _Contemporary Psychology as the journal with the highest impact factor among the nearly 500 psychology and psychiatry journals, and ranks it second among all the social science journals monitored by the Institute for Scientific Information (ISI). According to JCR, _Contemporary Psychology_ received 30 citations in 1996 and 1997, and had a total of 3 items considered "citable articles" published in the same period, yielding an impact factor of 10. For calculating the impact factor, ISI counts only original research articles, notes, and literature review articles in determining the denominator. This is arguable as book reviews, database reviews, letters to the editor are indeed cited. When book reviews, database reviews do get cited, the impact factor may increase significantly. The 1998 Social Sciences JCR produced an extreme ranking for an additional reason. The three items are clearly book reviews, but they were assigned the wrong document type (DT=ARTICLE) by ISI, thus qualifying for "citable articles." The irony is that this journal should not have been included at all in the stable of journals monitored by ISI as it is a journal of book reviews and does not have publications that would qualify it for coverage in JCR. The JCR policy of not counting certain document types when determining the denominator may unduly increase the impact factor of journals that do receive citations to those types of documents. The error in document type identification triggered an extremely high ranking in the example described. In the case of other journals - with correct and consistent document type assignment - the distortion in ranking may be far more subtle and far less likely to be spotted. <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><> Gretchen Whitney, PhD tel 865.974.7919 School of Information Sciences fax 865.974.4967 University of Tennessee, Knoxville TN 37996 USA gwhitney at utk.edu http://web.utk.edu/~gwhitney/ jESSE:http://web.utk.edu/~gwhitney/jesse.html SIGMETRICS:http://web.utk.edu/~gwhitney/sigmetrics.html <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><> From ronald.rousseau at KH.KHBO.BE Mon Feb 26 02:21:55 2001 From: ronald.rousseau at KH.KHBO.BE (Rousseau Ronald) Date: Mon, 26 Feb 2001 08:21:55 +0100 Subject: web search in AltaVista In-Reply-To: Message-ID: Dear colleagues, I would like to mention another caveat when doing web searches. This time in AltaVista advanced search. In this mode it is possible to specify 'one result per website'. Intuitively one now expects a smaller number of hits then without this specification. This is often the case, but when doing a search using the keyword 'peseta' (and this is just one example) one obtains almost four times more hits with 'one result per website' on than without it. This huge difference is certainly not caused by the fact that AltaVista's counts are not precise. Consequently I asked AltaVista's Technical Support Team. This is their answer: "When you do a particular keyword search, the spider brings up only those pages which are relevant to that keyword. However, when you specify only one result per website, the spider will pull up all the pages in the index with that keyword. This is the reason to obtain more results when you restrict the search of a generic keyword to one result per site." Besides the fact that this is something one must know when performing informetric investigations, there is the word 'relevant' in the answer. So, AltaVista decides (how?) which sites are relevant for you and which are not. Interesting!

Harter : harter at indiana.edu TITLE Web-based analyses of e-journal impact: Approaches, problems, and issues AUTHOR Harter SP, Ford CE JOURNAL JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE 51: (13) 1159-1176 NOV 2000 Document type: Article Language: ENGLISH Cited References: 11 Times Cited: 0 Abstract: This study(1) assesses the ways in which citation searching of scholarly print journals is and is not analogous to backlink searching of scholarly e-journal articles on the WWW, and identifies problems and issues related to conducting and interpreting such searches. Backlink searches are defined here as searches for Web pages that link to a given URL. Backlink searches were conducted on a sample of 39 scholarly electronic journals. Search results were processed to determine the number of backlinking pages, total backlinks, and external backlinks made to the e-journals and to their articles. The results were compared to findings from a citation study performed on the same e-journals in 1996. A content analysis of a sample of the files backlinked to e-journal articles was also undertaken. The authors identify a number of reliability issues associated with the use of "raw" search engine data to evaluate the impact of electronic journals and articles. No correlation was found between backlink measures and ISI citation measures of e-journal impact, suggesting that the two measures may be assessing something quite different. Major differences were found between the types of entities that cite, and those that backlink, e-journal articles, with scholarly works comprising a very small percentage of backlinking files. These findings call into question the legitimacy of using backlink searches to evaluate the scholarly impact of e-journals and e-journal articles (and by extension, e-journal authors).

Commercial search engines serve the "average user", who doesn't care whether there are 10,000 or 10,000,000 pages that mention his/her keywords, he/she only looks at the first few answers.

NetFirst (a FirstSearch service) covers only a very small slice of the Web. It may be "relevant" but not comprehensive. CORC may grow into the service Judit is calling for. But even then, neither NetFirst nor CORC will give us a tool to study or map the Web. Maybe the scientometric, particularly the cybermetric community should take this on. A part of me says it is a quixotic dream, but, hey, Dulcinea is worth it. OCLC has begun to meaure the Web. Could they provide the corporate structure to do what needs to be done? wally koehler > >Dear colleagues, >I found Ronald Rousseau's observation on the way AltaVista reports the >number of search results most fascinating.

For data on this, see the following: http://www.cogsci.soton.ac.uk/~harnad/Tp/Digitometrics/img009.gif This shows the shorter and shorter time until the first (and last, for all but the high impact papers) citation peak is reached: http://www.cogsci.soton.ac.uk/~harnad/Tp/Digitometrics/img011.gif This shows the usual publication lag, and the cross-over in the version cited (from the preprint to the postprint): More data are available at: http://www.cogsci.soton.ac.uk/~harnad/Tp/Digitometrics/index.htm http://opcit.eprints.org/tdb198/opcit/ and http://opcit.eprints.org/ijh198/ For the record, I do not share Greg's opinion that this effect, splendid though it is, is anywhere NEAR being self-archiving's greatest strength.

Chem. Int. Ed. V40(1), 139-143 (2001): Angewandte Chemie has been published since 40 years in the version of both a German and an International Edition (with different volume and page numbers), which has led to a number of problems in citation analysis. In its bibliographic source field the Science Citation Index (SCI) takes into consideration only the International Edition. Consequently only the citations of this edition are taken into account and the citations exclusivly in the German Edition are ignored. Standard citation analysis done by the method of "citation matching" (item by item procedure), in which the publications under evaluation are selected in the SCI, result in about a 20 percent underestimation on average. Another peculiarity causes an even larger underestimation: Since 1996 the reviews in Angewandte Chemie have begun with a full page picture, which is the starting page (first page). In the bibliographic source field of SCI (and in the Chemical Abstracts literature file as well) the starting page is sometimes stored one count too high, which results in an extensive underestimation of the reviews. Only the citations with the incorrect starting page (about 20-30 percent of all citations) are counted. Angewandte Chemie reviews are cited almost twice as often as the articles (communications), but the number of articles is about one order of magnitude higher. On the other hand double citations in both the International and the German Edition of the same papers result in an about 15 percent overestimation of the Journal Impact Factor (JIF98). The reason for this seeming contradiction is the different method used by ISI for determing the JIFs for their Journal Citation Reports (JCR): These are calculated by the method of "journal title matching", which investigates how often the specific journal names occur within the reference section of SCI in combination with certain publication years. It is shown that the JIF98 for Angewandte Chemie determined by ISI is obviously valid for both Editions together and not only for the International Edition. All investigations were done in SCI under STN International.

Through bibliometric citation analysis and mapping techniques the main actors at the university level are identified and the structure of the national research and development (R&D) system is described with respect to article production and publication patterns. Special attention is paid to patterns of research collaboration, nationally as well as internationally. This paper concludes that Taiwan is well integrated in the international scientific macro-networks. However the findings do not give support to the idea that Asian science and scientific thinking would differ from Western science; on the contrary, Taiwan has developed quickly into a science nation of significance by adapting Western scientific traditions and becoming integrated in international scientific networks.
