Introduction Bibliometrics is one of ways to assess the research performance of a country. I try to assess the science and technology performance in Indonesia with bibliometric approach. I hope result of this project can be become the guideline of Indonesian policy in science and technology. Indonesia conducted several main scientific conferences every year, mostly aiming to select prominent researches and funding the researches. Three main scientific activities include Science and Technology Research Grant (Toray), Integrated Prominent Research (RUT) and Partnership in Prominent Research (RUK) can become an indicator in assessing the performance of science and technology in Indonesia. The three grants is conducted to coordinate and give support to prominent researches that are suitable with industry need. The assessment of the three grants is based on the urgency and the usefulness of the research to solve priority problems in some fields in Indonesia, the originality and the accuracy. 1.1. Integrated Prominent Research (RUT) RUT has been conducted since 1992. The research proposals that success as a winner will be funded for 2-3 years. The activities of winning researches will be evaluated and valued in detail each year. The research that be no suitable on feasibility and RUT commitment nor has other problem to be continued, can be considered to terminate the fund. The winning research divided become 3 groups of research, comprise Technology, Applied Science and Basic Science. Each group comprises several fields. Every year decided the different or still the same priority fields, depend on the policy of the development ways in Indonesia. 1.2. Science and Technology Grant (Toray) Toray is collaboration between Japanese and Indonesian government, has conducted since 1993. Toray has the same rule with RUT. 1.3. Partnership on Prominent Research (RUK) RUK has conducted since 1995. So has the same rule with RUT and Toray. 2. Methodology 2.1. Collect of Data Data is collected since the beginning of each grant until year 2000. The number of papers and the range of year as follow: a. Toray 1993-2000 approximately 100 papers b. RUT 1992-2000 approximately 427 papers c. RUK 1995-2000 approximately 50 papers Amount of papers approximately 577 papers 2.2. Analysis I need bibliometric methodology to assess all of papers of the grants. 3. Length of Study The study is planned for 4 months. Starting on December 2000 until March 2001.

Regards Gopal T V ****************************************************************************** Dr. T V Gopal Assistant Professor School of Computer Science and Engineering Anna University Ph : (Off)+91-44-2351723 Chennai - 600 025, INDIA Extn 3340 e-mail : gopal at annauniv.edu (Res)+91-44-4454753 Home Page : http://annauniv.edu/staff/gopal ****************************************************************************** PART 1 : Problems with the present 'Metrics Methodology' ++++ The Current Methodology ++++ * The present 'scientometrics' such as citation index and impact factors are applicable to 'science communication only'. Rightly so because they were developed for that context. * Having 'global metrics' clearly establishes a sense of oneness amongst scientists and also gives a global ranking of their contributions. ++++ CONCERNS +++++ * The scientists are torn between the 'global competitive standing' and the local needs. The recognition/funding policies (national/international) being such, a typical scientist (today) is not meeting the local needs at all. This can produce internationally renowned scientists but robs off the vital scientific leadership imperative to solve local problems that are no where near the internatioanl frontiers of research in that field. (I acknowledge that this concern is being aired with immense hindsight) * The economics of paper production and the enormous time taken for reviewing and final publicaition in reputed journals puts unfair pressures on researchers and emerging fields. Very often, young researchers opt for the easy way of trucking with established researchers. * The current metrics enable one to migrate to a good place but to make his own place good is becoming unacceptably difficult. * IMHO, these metrics are grossly inadequate for the WWW context of reaching out information to people at large. * The present 'scientometrics' lead to a proliferation of super-specialisations (fields of research. journals, conferences ..) as this is the way to improve citation indexes and impact factors. There is thus less scope for inter-disciplinary activities. PART 2 : The Evolving Societal Frameworks For one of my books "The Origin of Thought" (currently under review), I made this analysis of the three forms of the societies. a) Agricultural Society + Primitive Economy + Trading in closed circles + Low degree of refinement and awareness + The half-life period of any knowledge acquired/skill is substantially large General Mindset : I belong to (/a family/a place/caste/group/party..) therefore I am capable b) Industrialised Society + The economy is product centered + The systems are well thought out and organised + 'Survival for the fittest' is the governing maxim almost replacing the maxim of natural creation 'balance' + The focus is almost entirely on 'Development' that requires (<20%) intellectual inputs. + Activities that require (>80%) intellectual inputs (visionaries) are put through enormous stress + This phenomenon is called 'Urbanisation'. General Mind set : I have (House/Car/Money..) therefore I am capable c) Knowledge-based Society + The focus must shift to 'People and Ideas' + Enables the grooming of a large percentage of visionaries (Both oriental and western wisdom is vital in achieving this) + The seeds of discovery that are always floating around need to be incubated in a larger percentage of receptive minds + Rapid change in the skills required to succeed Ideal Mind set : I know (to do/to get things done..) therefore I am capable. Our goal is to reach (c) with Informnatics (IMO, the science of placing a value on Information) and Technology as primary tools. So the metrics methodolgy should have different parameters. PART III : Aiming at Sustainable Development The basic spirit of industrialised society has been to profess that it is both tasteful and attractive to ocnsume resources in abundance and that to provide the oppurtunities for such consumption to all the people is to do them justice. This is the basis for the notion of 'development'. It is being extended to Informatics and Technology too. I think we need a major paradigm shift in defining the notion of 'development' in the Information age. Development in the industrial paradigm revolves around numbers. If we are not satisfied with what we have achieved then simply increase the numbers. I think a society with abundance of wisdom would do better even with shortage of things. For the sustenance of development, there must be ample learning oppurtunities that lead to building of infrastructure to facilitate wealth generation. Thus mere provision of information is not sufficient. We need to examine the 'economics of information'. We have to have some sort of a 'social subjectivity index' tagged onto the mertrics for Informatics and Technology. PART IV : Competence of researchers is judged based on originality of Idea and methodology.

If you place OR between a word and a phrase then Google gives you the same (and hence wrong) result as when you had put AND (or nothing) between this word and this phrase. An example: a search for eurozone OR "euro zone" gives 2580 hits. a search for eurozone AND "euro zone" gives also 2580 hits (and note that AND is not necessary in Google) further: a search for eurozone gives 14500 hits and a search for "euro zone" gives 35300 hits. Consequently: eurozone OR "euro zone" should have given 47220 hits (namely 14500 + 35300 - 2580). I have reported this to Google, so let's see what they will answer. By the way: in Google you need double quotes for phrases. A search for 'euro zone' yields exactly the same result as a search for euro AND zone, namely 219,000.

The guest editor for this issue will be Dr. Chaomei Chen of Brunel University. Background Thomas Kuhn's Structure of Scientific Revolution has generated profound and far-reaching impact over nearly four decades since early 1960s in a wide range of disciplines such as philosophy, history, social sciences, and physical sciences. Today, the advances of several key technologies in text processing, information visualization, and domain analysis provide potentially powerful means to detect and track the telltale signatures of the very existence of paradigms and paradigm shifts. This special topic issue will provide an interdisciplinary forum for researchers and practitioners to present the latest development of enabling techniques, methodologies, and case studies towards the realization of the ultimate goal of identifying and predicting the dynamics of a scientific paradigm and the structure of a scientific community. Topical Theme Authors are invited to submit original papers in related areas for the special topic issue. Example topics include, but are not limited to, the following: Characteristics of a paradigm Measurement and visualization of a paradigm Scientometrics Citation analysis Author co-citation analysis Domain analysis Visualization of social networks in scientific communities Visualization of knowledge structures Visualization of changing vocabularies of a subject domain Visualization of classic and landmark works Case studies of competing paradigms Case studies of a paradigm shift Research agenda Practical implications to information science as well as to scientific activities Inquiries and Submissions Inquiries should be made to the guest editor via email, fax, or telephone.

The current paper utilizes that theory as the context for employing bibliometrics to uncover the publishing and patenting citation patterns in a group of twelve US pharmaceutical companies over a 13-year period. Our initial findings suggest that firms self-cite a great deal, and that they rely heavily on public science. In addition, we found that Merck and Co. is the most frequently cited company in both the science and technology areas, though somewhat less so in technology. The managerial implications, particularly from a knowledge perspective, are discussed as well as some suggestions for future research.

Gangan Prathap : e-mail : gp at cmmacs.ernet.in TITLE : Arun's law of impact factor depreciation AUTHOR Prathap G JOURNAL CURRENT SCIENCE 77: (11) 1405-1407 DEC 10 1999 Document type: Article Language: English Cited References: 2 Times Cited: 0 Addresses: Prathap G, Natl Aerosp Labs, Bangalore 560017, Karnataka, India. Natl Aerosp Labs, Bangalore 560017, Karnataka, India. Publisher: CURRENT SCIENCE ASSN, BANGALORE PAPER: Arun's law of impact factor depreciation CURRENT SCIENCE, VOL. 77, NO. 11, 10 December 1999 In a very perceptive article recently, Arunachalam1 writes, 'Very often Indian authors publish papers in journals above a certain threshold impact factor (IF), but these papers do not get cited as often as would be expected on the basis of the IFs of the journals. In an earlier paper I showed that Indian papers often lower the IF of journals'. Arunachalam goes on to quote the work of Tibor Braun and colleagues that 'in most fields the relative citation rates of India (ratios of actual citation rate/expected citation rate) is less than one'. When I related this observation to my wife, she drew my attention to an interesting sociological fact that several decades ago, as Asians (mainly from the Indian sub-continent) increasingly immigrated to UK, and inevitably, as Asian families moved into what were once all-white neighbourhoods, the real estate values of these areas fell immediately. So here, we have the bibliometric (scientometric) equivalent of a Law of Impact Factor Depreciation - an editor of an international journal accepts an Indian (or for that matter, any Third World) paper at great risk to the IF standing of her journal! Almost as if on cue, I was working on a very similar theme recently: the weakness of the IF criterion to assess the quality of scientific output of any state or institution. One way to approach the problem of Quantitative Research Assess-ment is to employ the Impact Factor Approach. This is a prospective projection, assuming that a paper that has been published in a high IF journal is more likely to be well utilized or cited than a paper in a less prominent journal. We have considered Arunachalam's view that there is evidence to the contrary. He writes in the same article, in lines immediately preceeding the earlier quotation, 'One has to be extremely cautious in interpreting the data [IF] .... Ideally, one should count the number of times a paper is cited and see in which journals these citations occur, rather than merely look at the IF of the journal in which a paper is published'. My exercise, outlined below, showed that this is really true, by carrying out a retrospective analysis. In fact, it will turn out that papers which have appeared in high IF journals may sink without a trace and that the really good papers will attract citations in excess of the number expected for that issue of that journal (the expected citation rate). What I have done is to track such papers which have a relative citation rate (RCR) greater than 1, implying that actual citations received by the paper are greater than that expected of a contribution in that category in that journal. To ensure that only the really good journals are screened, one can consider only papers that have originally appeared in journals which have an XCR greater than a prescribed and meaningful threshold. The exercise was carried out with some statistics I have of the National Aerospace Laboratories' (NAL) record in this aspect of research assessment. Recently, we procured the Institute of Scientific Information's (ISI) Institutional Citation Report. Arguably, this allows us to compile an objective assessment of the published literature originating from NAL during 1981-1997, the period covered by the ISI database. It is proposed to conduct the Research Assessment exercise by evaluating the performance of published papers using the RCR > 1 criteria, where RCR is taken as the ratio of actual citations received to the expected citation rate (XCR). The XCR is the average citation per paper based on the journal title, year of publication and type of document. Thus, a paper published earlier should be expected to have more citations than the one published later. Categories (i.e. type of document) also matter. A full paper, a note and a letter to the editor may receive different citations. This is why the RCR approach may be better than using the IF or citations approach as is usually done. What I have done is to choose all items which have appeared from NAL in a journal issue and category where XCR > 10 from the ISI database (57 papers out of the 587 papers that had NAL listed in one of the author's addresses in the ISI database). This is a strict criterion, considering that such distributions are highly skewed, with long tails, and with the mean likely to be very much to the right of the median. These papers have appeared in what can be considered to be the best journals ever used by NAL scientists during 1981-1997, implying that they have the highest IF. However, this does not mean that the paper which is fortunate to appear in such a prestigious journal will ever be used. In fact as Table 1 shows, the 57 papers which belong to this category include many which have 0 and 1 citations since they appeared! In fact more than half the papers in this list have RCR < 0.5, confirming Tibor Braun's assessment that the RCR of Indian papers is less than one. My further criterion is to select from this list of 57, only those papers which actually received citations in excess of XCR. This is again an extremely strict criterion, especially considering the recent debate in Nature which establishes that papers from the Third World are often under-cited. Only 15 papers are found now (Table 2). Arguably, these are the best papers published from NAL during this period. The RCR criterion, more than the IF criterion, gives on a retrospective basis, an appreciation of what really are the papers that have been used over a well-defined period. Thus, this approach meets exactly Arunachalam's prescription1 that 'one should count the number of times a paper is cited and see in which journals these citations occur, rather than merely look at the IF of the journal in which a paper is published'. Discrimination here operates very unfairly at two levels. There is an accepted perception of discrimination regarding publication of papers. It is believed that a paper from 'weaker section' authors (e.g. women scientists, or those from the developing nations, as seen here) has to be much better than one from the 'stronger sections' to be accepted, i.e. the rejection criterion is more stringently applied to them. Seemingly, this would imply that their accepted publications would on an average, be of better quality. This is discrimination at one level. One would then expect that these papers would invite better citation rates. The operation of Arun's Law of IF depreciation is an expression of the fact that discrimination probably manifests at the citation level too - that papers from the 'weaker sections', which may arguably be better than average, are fated to receive lower than average citations. Such concerns about region-based citation bias have appeared earlier2. 1. Arunachalam, S., Curr. Sci., 1999, 76, 1191-1203. 2.

Non-Cryst. 1990 NAL papers arranged according to decreasing XCR which is the average citation per paper based on the journal title, year of publication and type of document. Thus, a paper published earlier should be expected to have more citations than the one published later. Categories (i.e. type of document) also matter: A full paper, a note and a letter to the editor may receive different citations. I have chosen all items which have appeared from NAL in an issue and category where XCR>10. These can be considered to be the best journals ever used by NAL scientists during this period (1981-1997), implying that they have the highest IF. It is easier to use this criterion than the IF values as the latter keep changing from year to year. However this does not mean that the paper which is fortunate to appear in such a prestigious journal will ever be used. In fact the 57 papers which belong to this category include many which have 0 or 1 citations since they appeared! Table 2. 15 papers from the 57 'best' papers of Table 1 which have RCR > 1, i.e. actually received citations in excess of XCR, ranked according to RCR Relative Cites Expected XCR Name of Journal Year Citation actually citation rank Rate received rate (XCR from (RCR) Table1 5.56 71.00 12.76 XCR-34 Int.

This is computed as the ratio of the actual citations received by the item published to the expected citation rate, XCR. The criterion here is to select from the list of 57 in Table 1, only those papers which actually received citations in excess of XCR (i.e. RCR >1). Only 15 papers are found now. Arguably, these are the best papers published from NAL during this period. Note now the reversal of fortunes: The RCR rank has little correlation to the XCR rank. One more confounding factor when XCR or IF value is used to rank quality is that these values vary across disciplines. Thus, in this instance, in a multi-disciplinary institutes like NAL, science-based papers earn much higher XCR than engineering-based papers and a large share of the former appears in Table 1. The use of RCR removes this complication, and the relative rankings have changed considerably. If one were to relax this criterion more generously, so that journals which have XCR>5 are all included, then we find an enlarged number of 150 papers from NAL appearing in such a list. Under this relaxation, about 37 papers from NAL (out of 587 listed in the ISI database) have received RCR>1, i.e. citations in excess of the XCR=5 stipulation.

The possibility of evaluation using scientometric methods provokes people into conducting the kind of exercise that Prathap has undertaken without taking into account that scientometrics has a kind of statistical validity which is eroded when very small specific samples are used. In that case, refining techniques when the methodology itself is in question seems to be missing the point. In this connection I would also invite comments on using scientometric evaluation for individual scientists/papers.

From isidro at CINDOC.CSIC.ES Wed Jan 10 08:24:21 2001 From: isidro at CINDOC.CSIC.ES (Isidro F. Aguillo) Date: Wed, 10 Jan 2001 14:24:21 +0100 Subject: More on search engines with scientometric purposes Message-ID: Dear colleagues: Following recent messages by Ronald Rousseau and with his cooperation I would like to share you some information about Internet search engines as a source of data for scientometric analysis. Perhaps if enough people are interested a special session about cybermetric methodology could be suggested to ISSI Sydney conference organizers, in a similar fashion to Colima's one. In the last months we tried to find out more about the inconsistencies of the search engines in order to provide information about "stability" and usefulness of these tools for quantitative analysis. We present some "tricks" valid in the time we tested (winter 2001). ** FAST (www.alltheweb.com). This large database (perhaps the largest) is updated each two months, more or less, so you have a long "time window" for calculating statistics without worries about the stability of results. There is no warning about when the database is updated, but that could be solved if you monitor the results of a control word. The advanced option is by far the best screen for working as you have access to (implicit) boolean queries and other interesting delimiters (our term for field restricted searching). The size (number of pages)and visibility (number of links received) of a website are easily derived from using "in the URL" and "in the link to the URL" options respectively. Selecting "must" and "must not" you can exclude self-citations, so true "sitations" are obtained (this boolean option works fine according to our results). There is a very useful trick regarding domain delimiter (there are two boxes, one to domains included and another to those excluded), as both boxes allows to use several (many) domains using blank space as separator (an implicit "OR" boolean). ** ALTAVISTA (www.av.com). Also very large and perhaps the most intuitive for our work, but unfortunately the most inconsistent engine. All the screens give different results, but as the advanced search provides the highest score and also works with explicit boolean operators it is the recommended option. However, use of these operators is not recommended for large samples as they provide wrong results. The database is altered (mainly due to saturation-avoiding procedures) in irregular periods, usually even several times during the same day. As a rule we suggest to obtain the sample in the same half day. The delimiters are well developed (domain, host, url and link) but they are not to be trusted if you combine (boolean) them or use it for comparing several samples obtained during different days. ** INKTOMI (www.hotbot.com and www.iwon.com). In theory both provide access to the same database, but the results are not exactly the same. We recommend using the advanced option of Iwon that is larger than standard one. Our personal feeling is that stability is longer than Altavista, but only extends to one or two days. Both support (with some level of confidence) booleans, and they use domain and linkdomain as more important delimiters. To obtain the numerical results in Hotbot you must go to the "second" (next) screen. ** GOOGLE (www.google.com). The second (?) largest database, the best search results but very few cybermetric options (almost no boolean support): The link operator refers mainly to the page, not to the complete website and for using site delimiter you must add a search term (our best results are obtained with +www, the plus sign is very important). ** INFOSEEK (www.go.com). The smaller of the reviewed databases, although with a recent high increase of size. Valid mainly for comparative purposes. Site and url are used as domain delimiters and link for citations, with implicit boolean support (in the past boolean do not work fine with large results). ** NORTHERN LIGHT (www.northernlight.com). Large database, with increased cybermetric options, even undocumented, as they not cited in the help provided (!). In the Power Search option you need to exclude "special collection" databases first, but then it is possible to use link (not documented but working fine) and Url delimiters. You can even use domain filters (undocumented too), as each country has a different control number in the query string (we can provide a listof such country numbers). Caution: minus sign (-) no longer works fine, so you should use NOT. We can provide additional information based on our experiences to those of you interested in using search engines, but caution is recommended as changes are very common and unexpected.

This is having far-reaching consequences on information and communication processes in the sciences and humanities. The Netherlands Institute of Scientific Information Services (NIWI), located in Amsterdam, has recently begun a programme of research to chart these changes. To take on the challenge of this groundbreaking interdisciplinary exploration into changes in academic research, NIWI is seeking 2 research associates (M/F) Vacancy number PZ 161 (40 hours full-time *1) to fulfil senior positions in our research group. NIWI is an institute of the Royal Netherlands Academy of Arts and Sciences. NIWI aims at providing scientific information in the fields of biomedicine, the social sciences, history and Dutch language and literature. In addition, NIWI provides information on research and researchers throughout the Netherlands. NIWI's main office is situated in Amsterdam. Recently, NIWI has formed a new research department to respond to the transformation of scientific publishing, communication and information. The successful applicants will be part of a team that will ultimately consist of ten people. NIWI's research goals are laid down in our research programme (http://www.niwi.knaw.nl/us/research/research.htm). Our hypothesis is that the sciences, social sciences and humanities are in the midst of an informational turn. This has important, yet largely uncharted implications for the researcher. Studying these implications is the main objective of our research programme. For this reason, we wish to characterise the informational turn, study its properties, in particular its implications for the use and creation of scientific information by the individual research group and scholar. Although this means that many aspects of the development and of the social impact of information and communication technologies will be involved in our research, our programme differs from existing research efforts, in that it puts the researcher in central place. Many research projects in information and library science are related to the development of specific technologies or information sources. There has been far less research on how the development of ICT affects the conduct of scientific research. Yet, it is the combination of technological and social developments at research group or individual scholar level, which is largely responsible for shaping the future of scientific information and communication patterns and needs. We have therefore chosen to concentrate our research on the changing role and needs of the researcher in scientific information and communication. As well as research aimed at creating new knowledge about the interaction between the researcher and ICT, we are also developing applied research. This is aimed at providing solutions to problems emerging from the practice of library and information services. Applicants should hold a PhD and be available to start work in the short term. They should moreover have acquired research experience in a relevant field. They will be working towards answering one of the following questions: 1. How can we understand the differences between academic disciplines and research domains with respect to the use of ICT in information and communication? 2. What influence are the new virtual research institutes and networks of research institutes - which rely heavily on communication through the Internet - having on the production of knowledge? Job responsibilities The research associates will be responsible for their own research project (one of the two mentioned above). They will be responsible for the acquisition of funding for additional research projects and submit grant applications. In collaboration with university researchers, some supervision of PhD students may be required. The members of NIWI Research act in an advisory capacity with respect to applied research projects within the institute. The main output of NIWI Research consists of journal publications, books, lectures and conference presentations. NIWI Research will also organise workshops and conferences on a regular basis. Research associates will be expected to share in these activities. Education and experience 1. Demonstrable relevant research experience, attested by a PhD degree and a list of publications in peer reviewed journals. 2. An excellent knowledge of the English language, both oral and written. 3. Experience in either qualitative or quantitative methods of research, preferably both. 4. Candidates should have a particular interest in transformations of academic research and be able to work independently and in a project-orientated manner 5. Candidates with creativity and who are inclined towards/ interested in groundbreaking work are encouraged to apply.

For some reason the idea came to me to try looking for citations outside of the usual citation index tools. I started with some general full text journal databases (Gale's Expanded Academic ASAP and EBSCO's Academic Search Elite) using my name and/or various paper titles as search arguments. Then I moved on to several Web search engines (e.g., AltaVista, Google, Northern Light) using the same search strategies. I pulled the results together and created the following Web page: http://www.lis.uiuc.edu/~b-sloan/pci.html While I did this out of personal curiousity, I'm interested to hear from others who may have done the same thing. What value do you think you derived from the exercise? Did you find out anything interesting about how your publications are used? I'm also curious to hear from folks who haven't done something like this, to see if you think this is a worthwhile exercise. Would this be a useful way for faculty to track the impact of their published work (both print and Web-based) for the promotion and tenure process? Also, how do you judge the relative importance of a citation from a Web resource, rather than a citation from a journal article? If your paper is cited in a journal article (especially a refereed journal), that's one thing. But since the quality of Web-based resources varies so much, do these somehow count for "less"? Guess I am thinking that, as the Web continues to change the way people both seek and publish information, how will we treat Web-based literature in gathering and analyzing citations?

A nice recent review which highlights the analogies between evaluation of web-sites and of publications is Jon Kleinberg, "Hubs, authorities, and communities" in ACM Computing Surveys 31(4), December 1999.

Probably the volume of results are not very high (statistically non significant) but the pattern is becoming evident. In some way (hypertext) links represent citations, but the true nature of linking is controversial. The published criticisms points out that bibliographic citation represents a more elaborated proccess than linking, but sometimes I feel two different concepts are mixed: popularity as measured by number of visits and visibility that is the number of external links pointing to website. A working hypothesis is that popularity and visibility are far different in "closed" areas like scientific ones, so visibility is really working as an indicator of impact (whatever that means). So, could Bernie Sloan check if there is (positive or negative) correlation between his most popular sites and his most visibles ones?. Obviously I am suggesting a simple "test" not a full paper ;-) Floor is open to other contributions ... > About a month ago I was playing around in Web of Science, looking for > citations to a couple of my papers.

The percentage of citedness for the highest impact journals is in excess of 90%. The ISI database that reports on these data is called Journal Performance Indicators. http://www.isinet.com/isi/products/rsg/products/jpi/index I suspect that you are being influenced by a report in Science about ten years ago in which a reporter got hold of some printouts he did not understand and misquoted the data. There was an excellent rebuttal by David Pendlebury of ISI which follows. http://www.the-scientist.com/yr1998/july/pendlebury.html } Science, 251:1410-1411, 1991 ---------------------------------------------------------------------------- ---- David A. Pendlebury Letters to the Editor Science, Citation, and Funding Hamilton's two articles about the percentage of journal literature that remains uncited within 5 years of publication require comment and further explanation. The figures reported by Hamilton -- 47.4% uncited for the sciences, 74.7% for the social sciences, and 98.0% for the arts and humanities -- are indeed correct. However, as Maxine Singer was quoted as saying in Hamilton's first article, it is necessary to know what's in the numbers before interpreting them. These statistics represent every type of article that appears in journals indexed by the Institute for Scientific Information (ISI) in its Science Citation Index, Social Sciences Citation Index, and Arts & Humanities Citation Index. The journals' ISI indexes contain not only articles, reviews, and notes, but also meeting abstracts, editorials, obituaries, letters like this one, and other marginalia, which one might expect to be largely un-cited. In 1984, the year of the data quoted by Hamilton, about 27% of the items indexed in the Science Citation Index were such marginalia. The comparable figures for the social sciences and arts and humanities were 48% and 69%, respectively. If one analyzes the data more narrowly and examines the extent of uncited articles alone (this information was not yet available when Hamilton wrote his articles), the figures shrink, some more than others: 22.4% of 1984 science articles remained uncited by the end of 1988, as did 48.0% of social sciences articles and 93.1% of articles in arts and humanities journals. It ought to be pointed out that the book represents a considerably more important vehicle of communication in the social sciences and humanities than in the sciences. The figures given above reflect only the journal literature of the social sciences and arts and humanities. The figures originally quoted by Hamilton seem to have been interpreted by many readers as some sort of measure of the health of U.S. science. The numbers, however, reflect a lack of citation of papers by authors the world over-not only those by U.S. researchers. This point was raised in Hamilton's first article. If one restricts the analysis even further and examines the extent of uncited articles by U.S. authors alone, the numbers are even less "worrisome." Only 14.7% of 1984 science articles by U.S. authors were left un-cited by the end of 1988. We estimate the share of uncited 1984 articles by non-U.S. scientists to be about 28%. (Comparable figures for social sciences and arts and humanities articles by U.S. authors are not yet available.) A certain level of "uncitedness" in the journal literature is probably more an expression of the process of knowledge creation and dissemination than any sort of measure of performance. A trend toward more or less "uncitedness," however, might be meaningful. For the 1980s, we see no such trend in the scientific literature: the numbers are essentially flat, both for the United States alone and for the world. In the social sciences, however, we do detect a decrease in uncited papers -- from 49.7% for 1981 articles to 45.3% for 1985 articles. In the arts and humanities, the figure of 93% uuncited is fairly steady from 1981 through 1985. This, we hope, serves to illustrate the great range of statistics one can derive depending upon what "cut" is made from the ISI databases. For example, articles published in the highest impact journals like Science are almost never left uncited. We will be generating, over the coming months, article-only statistics, both U.S. and worldwide, for subdisciplines in the sciences, social sciences, and humanities, corresponding to the overall database statistics referred to by Hamilton in his second article. We have not yet produced a report on these statistics, but in light of the great interest in the numbers, we will now do so. We hope this information clarifies the record and will end further misunderstanding or politicalization of these statistics. David A.

There is a tendency to assess quality of scientific journals with the help of the IF. An analysis of the changes in the EF over time in the different specialities may help to further enlighten the worth and problems of the IF Methods: The Ifs listed under the subheadings Anethesiology and Emergency Medicine & Critical Care in the Science Citation Index - Journal Citation Report were descriptively analysed over the past 10 years. Additionally, IFs of some other important journals (subheadings Surgery, Cardiovascular, General Medicine) were analysed. Results: The IF of most of the journals showed a constant increase over the years (average in Anesthesiology: +65%; average in Emergency Medicine gr Critical Care: +145%). Ifs of the highest ranked journals of other specialities showed a similar increase over the years (average in surgical journals: +56%; average in cardiac journals: +59%; average in general journals: +40%). More Anesthesiology and Emergency Medicine & Critical Care journals originated from the USA show an IF >2.0 over the past 10 years than do European journals. Conclusion: Although the value of the IF is highly controversial, it is a frequently used tool to assess rating of a medical journal. Anesthesiology and Emergency Medicine & Critical Care journals showed a continuous increase in the IF over the past 10 years.

Collections Acquisitio ns & Technical Services 23(4). p.411-419, Winter 1999 The readers of SIGMETRICS may be interested in my article, "An Assessment of Social Sciences Coverage by Four Prominent Full-Text Online Aggregated Journal Packages" in Library Collections, Acquisitions, and Technical Services, Vol. 23, No. 4, pp. 411-419, 1999. I especially hope that someone will replicate the study with updated data. This study is from 1996 data. The content of the packages has changed since then, as have prices and impact factors. Unfortunately, I am not able to repeat the study at this time. SUMMARY OF ARTICLE The cost effectiveness and quality of full-text journals are analyzed for four prominent online aggregated journal packages: EBSCOhost Academic Search FullTEXT, UMI Proquest Direct Periodicals Research II, IAC?s Expanded Academic ASAP, and H.W. Wilson?s OmniFile. Price data from EBSCO?s Librarians? Handbook are used to assess the total, average, and median value of social sciences journals in each package. Quality of social sciences journals coverage is compared based on citation impact factors as recorded in Journal Citation Reports?Social Sciences Edition. This comparative analysis suggests that the UMI package has the highest quality journals, followed very closely by IAC. The journals in EBSCO?s package are of slightly lower quality as measured by impact factor, but are still close in quality to UMI and IAC. The Wilson OmniFile has fewer full-text social sciences journals, and trails the other packages in average impact factor and average prices. But except for the much lower number and prices of full-text social sciences journals found in the Wilson OmniFile, the differences among packages are not dramatic. The average impact factors of full-text journals in each package fall within .24 standard deviation of the mean for all journals in SSCI. Given the many factors that should be considered in selecting access to online journals, variation in prices and impact factors for full-text journals may not deserve to be the dominant selection factors, at least not for these four packages.

It identifies the determinants of the most prevalent measure of influence for finance journals, the Social Sciences Citation Index impact factors. It finds that impact factors are affected by citations outside the finance field, are not affected by the distribution of published articles across subfields, and are good predictors of the long-term citation counts of articles. The citation impact factors are reduced for both the Journal of Financial Economics and The Journal of Finance by their publication of other than regular articles.

Publisher: BLACKWELL PUBLISHERS, MALDEN IDS Number: 318WZ ISSN: 0022-1082 CONCLUSION: The prevalent use of the SSCI impact factor as a means of identifying the most influential journals in finance appears to be justified. In the case of JF, JFE, and RFS, the impact factors are the result of the publication of articles that are, on average, heavily cited both inside and outside the field of finance. Further, the impact factors for JF, JFE, and RFS are not biased upward because they publish articles in areas of finance that are more likely articles of short-term interest. In fact, the results show that impact factors are good indicators of longer-term influence. However, the impact factor for JF is negatively biased by the shorter papers and proceedings papers it contains, as is the impact factor for JFE because if its inclusion of clinical papers. Based on their full-length articles alone, JF and JFE would have even higher impact factors. This evidence is consistent with the impact factors for the three journals being the result of influential articles, and not the result of any bias.

The purpose of this study is to characterise international scientific cooperation in Korea through the numbers of internationally co-authored papers covered by the Science Citation Index CD-ROM, 1994-1996. A total of 3,627 collaborative papers published in 1,083 scientific journals were selected to analyse papers written in collaboration between Korea and other countries. The data reveal that Korea's coauthorship level with other countries was relatively high, representing 26.8% of national output. Among the collaborative papers, a large majority of the papers (84%) were authored by researchers at universities, while about 10% came from scientists at government-supported institutes and only 6% from industry. The country with the highest rate of cooperation with Korea is the USA (42%), followed by Japan, Italy, Germany, the UK and France. Considering the strong interaction between Korean and American science, economic and political factors appear to play a strong role in the international co-authorship process. The results show clear variation in levels of international cooperation according to the disciplines: technology, agriculture and earth sciences represent local interests, while physics, chemistry and biology are mainstream subjects.

Tn absolute numbers of publications between 1995 and 1999, Germany is comparable to other large European countries. However, Germany ranks definitively last among 10 major developed countries if the numbers of scientific papers per year are seen in relation to the economic capability. This is true for the whole of biomedical research, but it is even more exaggerated for ageing research. There are potent groups in German ageing research capable of producing a good fraction of high-impact papers, however. There are many more researchers in areas highly relevant to gerontology which recently became attracted by gerontological problems. However, the importance of modern biogerontology has not made clear to decision-makers in Germany, so that structural and financial limitations will probably prevent any significant rise in the near future, which would be necessary to keep Germany along with other developed countries.

Publisher: PERGAMON-ELSEVIER SCIENCE LTD, OXFORD IDS Number: 322XV ISSN: 0531-5565 Quote from above paper : "A stratification of papers in gerontological research according to journal impact factors will essentially measure two factors: First, it will indicate to a large extent the fraction of biological, and especially molecular research within gerontology, because those papers do have a much better chance to be published in high-impact journals. Second, it will indicate how far authors and reviewers alike believe whether the paper might have an impact on the biomedical research community as a whole. To strengthen the latter aspect, journal impact factors of three and ten were chosen as borderlines for stratification. That means, the vast abundance of papers with a more specific relevance to gerontology, whether biological, medical or psychological, will be found in the first group. It should be mentioned that this group still includes even the leading gerontological journals, a fact which reflects most of all the (still) small size of the fIeld. That means that papers with high relevance to the field are to be found in this group, and is one example to show that stratification by impact is not synonymous with quality. The group of papers published in journals with impact factors between three and 10 will consist mainly of papers with are thought to be relevant not only to ageing research but at least to one or the other branch of biomedical sciences as well. Finally, papers on ageing research which make it into highest impact journals are evidently regarded as being of outstanding quality and importance. Fig. 3 compares the performance of the three countries, Germany, UK, and USA, in this respect. Journal impact factors were checked for papers published in gerontology (defined as above with the exclusion of papers on dementia but not ageing) in 1998 (from the US: only the first 400 papers published in 1998). Interestingly, the fraction of high- and highest-impact papers from the US is clearly lower as compared to either the UK or Germany. A nonquantitative survey indicates that this difference is due to a much higher fraction of papers devoted to psycho-social aspects of gerontology in the US. Otherwise, Fig.3 demonstrates that the percentage of gerontological papers published in high- and highest-impact journals from authors in Germany is at least comparable to that in other countries. To conclude, it has to be stated that the output of gerontological research from Germany is low in absolute numbers and is actually embarassingly low in comparison to Germanys economic power. However, among the papers produced there is a reasonable fraction of publications which are expected to be of high impact." ------------------------------------------------------------- (c) ISI, Reprinted with permission Please visit their website at www.isinet.com ------------------------------------------------------------- From gwhitney at UTK.EDU Mon Jan 22 18:41:56 2001 From: gwhitney at UTK.EDU (Gretchen Whitney) Date: Mon, 22 Jan 2001 18:41:56 -0500 Subject: ABS: Diospatonyi, A revisited auditing of the analytical abstracts database Message-ID: E-MAIL: T.

The results have shown that the database has substantially improved its coverage by editorial reorganizations in 1994. The only open problem which has been revealed is a somewhat excessive emphasis given to the coverage of the journals on the lower tail of the journal distribution. The suggestion is made to reduce his emphasis in favor of an even more complete coverage of some "titled" analytical journals.

The search comprised an article-to-article evaluation ('hand search') of 12 peer-reviewed anaesthesia journals, as well as an Internet-based ('SilverPlatter') Medline(TM)-search (3.900 medical journals, US National Library of Medicine), both limited to original articles, case reports, reviews and editorials. Selected physical characteristics, for example the number of infants and children aged 0-14 yr old, the number of anaesthetists (specialists) and current impact factors (Science Citation Index) served to assess publication activity and international recognition. During the time period studied, 2259 articles (377/yr) were published on paediatric anaesthesia in 295 medical journals. The articles were primarily written in English (85.1%) and the majority originated from the USA (35.4%) and the UK (12.6%). The largest number of publications (77.7%) appeared in 29 anaesthesia journals, all referenced in Medline(TM), with 46% being published by only five journals. Most authors published in journals of their home country/region. Authors from the UK ranked highest in publication activity, followed by those from Canada, Switzerland, Sweden and Denmark. The highest impact factor was achieved by US and UK authors. We conclude that publications on paediatric anaesthesia are clustered in a small number of journals and are written predominantly by authors from English-speaking countries, who achieved the highest international recognition.

This can be performed in either of two ways. Method 1 1) Plot the data on a XY (Scatter) graph 2) Select the data series on the graph and "Add Trendline..." in the "Chart" menu. 3) Select "Power" type of regression curve, in the Option Tab, select "Display equation on chart" as well as "Display R-squared value on chart" Method 2 1) Select a two column by five rows area on the spreadsheet where you data is 2) Type "=Linest(log(Y:Yn);log(X:Xn);1;1)" where Y:Yn is the range of the Y-data (frequencies) and X:Xn is the range of the X data (number). 3) Press simultaneously Ctrl-Shift-Enter to create an array-formula. Read Excel's help to interpret the stats. To convert the b of the intercept, raise 10 to the power of b to obtain the constant of the power law (c=10^b. The advantage of using these methods based on the least-square fit is to obtain the R-Value as well as, in the case of spreadsheet based method (Method 2) the F-statistics. The t-test can also be calculated from the results of the formula array. People who are interested can send an email and I'll send them a template that calculate regressions from the original Lotka (1926) data in both the number-frequency (as in Lotka's paper) and rank-frequency (as in the form used by Auerbach long before Zipf) forms. The rank-frequency form of Lotka falsify the assertion of Zipf that data following Lotka's law (not really a law since it fits only his data) would produce a rank-frequency distribution with a power of 1.

Cybermetrics, Vol. 4 (2000). Issue 1. Paper 3 http://www.cindoc.csic.es/cybermetrics/articles/v4i1p3.html Abstract JASIS has consistently been identified as one the major information science and library journals both in the United States as well as for the rest of the world (Kohl & Davis, 1985; Rice 990; Siddiqui, 1997; Wormell, 1998; Nisonger, 1999). The Journal has also long been regarded as one of the discipline's chief archival documents. And archival documents retain their influence over their disciplines far longer than do other quality publications (Griffith et al, 1979). Based on our analysis of articles published in AD and JASIS from 1950 to 1999, we find that there has been a slow but perhaps inevitable shift based first on the single non-funded researcher and author to a much wider research and publishing participation among authors, regions, corporate authors, and countries. This suggests not only cross-fertilization of ideas, but also more complex research questions. A small trend toward greater external funding further reinforces this finding. We also chose to close our data collection with the last number of volume 50. This is less by design than by serendipity, since the data collection and initial analyses were conceived as a class project for the Elements of Research course of the School of Library and Information Studies at the University of Oklahoma for fall semester 1999.

As has been pointed out by many people before (though perhaps not on this list), performing least-squares fits to data in order to fit a power law is fraught with danger. The principal objection to this method is that, with logarithmic fits, the statistical fluctuations in the logarithms of the data are greater in the downward direction than in the upward one, for obvious reasons. This effect is more pronounced in the tail of the power law, and this has the result that there is a systematic tendency for least-squares fits to overestimate the slope of the power law. How much they overestimate depends on the size of the statistical fluctuations, and is therefore rather hard to control for. For this reason simple least-squares fits are to be avoided. Two common methods are used to circumvent this problem, neither of which is perfect: (1) One calculates a backward cumulated histogram of one's data (also called a rank/frequency plot).

Those who have tried to replicate Lotka's work will have noticed that although he did no mention of it, Lotka excluded some data from his dataset. One has to transform some of the data through the use of outliers to alleviate the problems outlined by Mark, in the case of number-frequency distributions in scientometrics at least. As he so rightly pointed out, regressions will be overestimated or underestimated regardless of whether the data is number-frequency or rank-frequency. In number-frequency distributions, it is very difficult to calculate a valid regression whatever the method used. This is inherent to the data and not to the method. This applies more to problems in the social sciences than in the natural sciences, although I do not pretend it is absent in the latter. In social systems, for number-frequency distributions, it is very difficult to calculate a valid exponent without the use of outliers. The use of rank-frequency only shifts the problem around. The solution that I have favoured to calculate rank-frequency is to minimise this effect by binning the data, hence, using the mid-point for any given frequency, the data becomes a mean-rank - frequency distribution. Once this transformation is accomplished, I'm not certain that least-square fitting is so bad, hence my suggestion to test the difference obtained by maximum-likelihood and least-square methods, and why not the maximum-entropy method while we're at it. In the end, the epistemological question remains of how to choose the best answer, and hence, the best method. If we do not know a priori the power coefficient of a distribution, and given the weakness of our theoretical knowledge on the why of power-law distributions in social systems (sorry for those drawing (weak) analogies between sand-piles, dinosaur extinction, and scientific publications, this is not a theory nor an explanation for what we observe in scientometric research) there is no foolproof method to determine which measure is the "real one".

It would be interesting to compare the extent of the difference between this method > compared to using least-square fits. As has been pointed out by many people before (though perhaps not on this list), performing least-squares fits to data in order to fit a power law is fraught with danger. The principal objection to this method is that, with logarithmic fits, the statistical fluctuations in the logarithms of the data are greater in the downward direction than in the upward one, for obvious reasons. This effect is more pronounced in the tail of the power law, and this has the result that there is a systematic tendency for least-squares fits to overestimate the slope of the power law. How much they overestimate depends on the size of the statistical fluctuations, and is therefore rather hard to control for. For this reason simple least-squares fits are to be avoided. Two common methods are used to circumvent this problem, neither of which is perfect: (1) One calculates a backward cumulated histogram of one's data (also called a rank/frequency plot). This much improves the statistical fluctuations, but has the undesirable property that successive data points become correlated, making the simple statistical estimate of error on the fit invalid. (2) One performs logarithmic binning of the data, i.e., binning where the widths of adjacent bins are a constant ratio, and normalizes by bin width. This reduces the effects of the fluctuations, but for power laws with slope greater than -1 it does not eliminate them altogether. (This latter is my favored method.)

This implies the incorporation of our journal to the most selected group of international scientific publications and awards it with the desired impact factor. The aims of this paper are firstly to review the basic bibliometric concepts that govern the influence of publications and research groups on biomedical sciences; secondly to know the present status of the scientific production in neurosurgery and the situation of Spain in the world and European context, analyzing its national distribution and evolution during the last years and finally, to show the present status of Neurocirugia, considering some aspects in order to improve its indicators in the future. Material and methods: A review of the neurosurgical literature in 1998 was done as well as a follow-up of the national production between 1987-99. The articles were distributed according to the authors geographical origin, journals, area and type of investigation. Data were mainly obtained from MEDLINE. The main bibliometric variables analyzed were the total number of articles and the impact factor. The absolute data were weighted up with demographic and economic variables in order to know the relative potential of each country. Results: Three thousand and twenty one articles that were published in 314 journals were localized. Following the total number of articles and the cumulated impact factor, the main producing countries were the United States, Japan and Germany. Spain holds the ninth position by number of articles and the thirteenth one by impact factor. The gross domestic product has been the weighting variable that has demonstrated a stronger correlation with the scientific output generated by each country. By applying it, our country descends considerably. However, the Spanish production shows a favourable tendency during the last years, not only because of the total number of published articles, but also for the theoretical better quality of them. Conclusions: Despite of the achievements during the last years, the Spanish neurosurgery holds a lower position than the one it should according to our country economical potential. The challenge of the forthcoming years must be working in order to improve these indicators.

In this paper, an assessment of the Spanish scientific journals on Geology is reported. The aim of this work is to provided elements for a diagnosis of the present situation of these domestic journals. The analysis is based ion indicators that refers to the formal quality, compliance with international standards, timeliness, composition of the editorial board, and international dissemination of journals. Presence of funded papers has also been analyzed as an indicator of journal quality. The present paper is part of a project aimed to help in the development of a methodology for the assessment of domestic journals and the role they play in the Spanish R&D system.
