Could you please advise on the necessary search (e.g. through links and/or contact info of appropriate persons)?" I'd appreciate it if anyone could make any suggestions as to how this person might go about this kind of search for citiations. Thanks!

The basic idea is that articles that will have many citations were in a similar position topologically in the past. To validate this hypothesis, we investigated the correlation between future times cited and three measures of centrality: clustering centrality, closeness centrality, and betweenness centrality. We also analyzed the effect of aging as well as of self-correlation of times cited. Case studies were performed in the two following recent representative innovations: Gallium Nitride and Complex Networks. The results suggest that times cited is the main factor in explaining the near future times cited, and betweenness centrality is correlated with the distant future times cited. The effect of topological position on the capability to be cited is influenced by the migrating phenomenon in which the activated center of research shifts from an existing domain to a new emerging domain. ________________________________ Received: 16 January 2006; Revised: 9 April 2006; Accepted: 21 April 2006 Digital Object Identifier (DOI) 10.1002/asi.20529 About DOI Journal of the American Society for Information Science and Technology Volume Issue 6 , Pages 872 - 882 Published Online: 2 Mar 2007 Copyright (c) 2007 Wiley Periodicals, Inc., A Wiley Company -------------- next part -------------- An HTML attachment was scrubbed...

You accessed the entire article (html version, in three pieces), freely, online at the AmSci's own website. In addition, Alma Swan, an advocate of self-archiving, will no doubt self-archive the article in her Institutional Repository. The fact that the American Scientist (a subscription-based journal, not a Gold OA journal) does not give away its PDF for free is not an irony, and is not a handicap, as long as AmSci does not try to prevent Alma from self-archiving (and it does not). Hence the version you read free on the AmSci site is in fact a *bonus*, not an irony! Stevan Harnad PS You could, of course, have downloaded the HTML version you accessed! (There are still *profound* misunderstandings about the true power and potential of the online medium -- and of what comes with the territory, when you make a text OA.)

Indeed this is correct. OR I could have pdf'd the html. OR I could print the paper and scanned the output to PDF. OR I could email the author and ask for a PDF copy. The greater irony is that this excellent paper say "To provide open access, all that is needed is for each scientist to place a copy of each article, as soon as it has been peer-reviewed, into an open repository at his institution. Known as self-archiving, this act takes a few minutes and costs a scientist nothing." >>From what I can tell this paper has not been self-archived at author's home institution even though it is obvious that it has passed peer reviewed OR maybe I just wasn't able to find the correct archive location. Did I miss it? Don't take my comments the wrong way. I am an advocate of OA - FULL OA. It is the irony between what is preached and what is practiced that amuses me.

We give each author a copy of the PDF and do not restrict the author's use of it. Exception: We advise that when a PDF contains material (such as commercial photography or fine art) belonging to a third party, additional permissions may be required. In fact, I'm happy to say that transfer of copyright to Sigma Xi is voluntary, and we allow authors to retain whatever rights are important to them. Publishers don't have to dictate these things, even though standardized publishing agreements are the norm in journal publishing and are generally easier to administer.

From eugene.garfield at THOMSON.COM Fri Apr 6 16:28:26 2007 From: eugene.garfield at THOMSON.COM (Eugene Garfield) Date: Fri, 6 Apr 2007 16:28:26 -0400 Subject: The pulsing structure of science: Ortega y Gasset, Saint Matthew, fractality and transfractality by Bailon-Moreno R et al in Granada Message-ID: Title: The pulsing structure of science: Ortega y Gasset, Saint Matthew, fractality and transfractality Author(s): Bailon-Moreno R (Bailon-Moreno, Rafael), Jurado-Alameda E (Jurado-Alameda, Encarnacion), Ruiz-Banos R (Ruiz-Banos, Rosario), Courtial JP (Courtial, Jean Pierre), Jimenez-Contreras E (Jimenez-Contreras, Evaristo) Source: SCIENTOMETRICS 71 (1): 3-24 APR 2007 Document Type: Article Language: English Cited References: 35 Times Cited: 0 Abstract: By a new fractal/transfractal geometry of the Unified Scientometric Model, it is possible to demonstrate that science presents an oscillating or pulsing dynamic. It goes alternatively through two types of phases. Some phases are fractal, with crystalline networks, where the Matthew effect clearly manifests itself with regard to the most notable actors and those that provide the best contributions. The other phases are transfractal, with deformed, amorphous networks, in which the actors, considered mediocre, present greater capacity to restructure the network than the more renowned actors. The result after any transfractal deformation is a new crystalline fractal network. Behind this vision lies the Kuhn paradigms. As examples, the scientific fields of surfactants and autism have been analysed.

Material and Methods: The search was carried out in four international periodontal journals: Journal of Periodontology, Journal of Clinical Periodontology, International Journal of Periodontics and Restorative Dentistry and Journal of Periodontal Research. The Classics, that are articles cited at least 100 times, were identified using the Science Citation Index database. From every issue of the journals that contained a Classic, another article was randomly selected and used as a Control. Results: Fifty-five Classics and 55 Controls were identified. Classic articles were longer, used more images, had more authors, and contained more self-references than Controls. Moreover Classics had on the average a bigger sample size, often dealt with etiopathogenesis and prognosis, but were rarely controlled or randomized studies. Conclusions: Classic articles play an instructive role, but are often non-Controlled studies.

The assumption that citation and publication practices are homogenous within specialties and fields of science is invalid. Furthermore, the delineation of fields and among specialties is fuzzy. Institutional units of analysis and persons may move between fields or span different specialties. The match between the citation index and institutional profiles varies among institutional units and nations. The respective matches may heavily affect the representation of the units. Non-ISI journals are increasingly cornered into "transdisciplinary" Mode-2 functions with the exception of specialist journals publishing in languages other than English. An "externally cited impact factor" can be calculated for these journals. The citation impact of non-ISI journals will be demonstrated using Science and Public Policy as the example. _____ Loet Leydesdorff Amsterdam School of Communications Research (ASCoR) Kloveniersburgwal 48, 1012 CX Amsterdam Tel.: +31-20- 525 6598; fax: +31-20- 525 3681 loet at leydesdorff.net ; http://www.leydesdorff.net/ Now available: The Knowledge-Based Economy: Modeled, Measured, Simulated. 385 pp.; US$ 18.95 The Self-Organization of the Knowledge-Based Society; The Challenge of Scientometrics -------------- next part -------------- An HTML attachment was scrubbed...

The computation of anticipatory systems enables us to distinguish between these domains in terms of weakly and strongly anticipatory systems with a structural coupling between them (Maturana, 1978). Anticipatory systems have been defined as systems which entertain models of themselves (Rosen, 1984). The model provides meaning to the modeled system from the perspective of hindsight, that is, by advancing along the time axis towards possible future states. Strongly anticipatory systems construct their own future states (Dubois, 1998a and b). The dynamics of weak and strong anticipations can be simulated as incursion and hyper-incursion, respectively. Hyper-incursion generates ?horizons of meaning? (Husserl, 1929) among which choices have to be made by incursive agency.

I take it this is what the phenomenology of meaning looks like these days. Not that I pretend to understand phenomenology, so please correct me if I am wrong. I also take it that the interpretation of the parameters in the very interesting equations, as well as the technical concepts being used, is to be found in the cited references. Since I have also presented a theory of the nature of information here, I thought it appropriate that I speculate upon the difference between this body of work and my own. CF: http://www.bydesign.com/powervision/Mathematics_Philosophy_Science/information.html My work derives from the tradition of analytical philosophy and mathematical logic begun by Russell and Wittgenstein. I suggest that it is looking at meaning in a very narrow sense, as exemplified by the atomic proposition. The phenomenological tradition is looking at meaning in a very broad sense, what it is to be meaningful if you like. The human condition is rich enough to accommodate both approaches and so I do not see any disagreement here between us. The question is if there is any connection?

I would be inclined to think about information and information structures in terms of the dimensionality of the probability distribution. For example, a structure requires a network and thus a two-dimensional matrix can contain this information. An information system would additionally require that the structure is extended along the time axis and this would lead to matrices at each moment of time and thus a three-dimensional cube of information would be required. Unstructured information can be considered as a vector. One can extend beyond a three-dimensional array towards a hyper-cube of information. In The Evolution of Communication Systems, Int. J.

However, a so-called "rational reconstruction" in mathematical logic has the specific aim of providing a technical definition of an ordinary language concept. Acceptability is usually a matter of capturing the acutal use of the term. Shannon information, if I may call it that, includes random strings of symbols, which the ordinary concept of information does not, so it fails the test. It is too broad. My core definition of information, as the propositional content of expressed thought, comes pretty close, but has yet to be tested. Note too that on my definition information is not a physical thing, although it always has a physical aspect, namely the act of expression, normally speaking or writing.

For my part, I agree that most of the information structures I am talking about can be represented as matrices, although I prefer to visualize them as linear, tree-like or network-like arrays, depending on the case. Each structure is defined by some relation or set of relations among the pieces of information. So far so good. Given my definition of information, each piece of information is theoretically an atomic proposition. However, since the number of atomic propositions in a sentence is typically roughly equal to half the number of words, we usually work at a courser scale. Pieces of information may be sentences, whole documents, or even collections of documents. As I explain, pieces of information can be related according to their propositions, their physical expressions, their referents (what the propositions are about), or a combination. For any given body of information there will usually be a large number of important relation types, so there are in fact many matirices of interest. And yes many of these change over time. In this context the matrices all exist, whether we know it or not. That is, how the information is related is a fact about the information, independent of our analysis. Important relations (or matrices) in common use range from alphabetical order applied to some aspect of the expression, to the so-called topic, which is usually an aspect of what the information is about. Many popular categorization schemes merge and confuse what are actually different relations. Probability does not enter into it so far as I can tell, so I am interested how this may relate to your matrices? Perhaps that has to do with the change over time?

Repeating the analysis for different years then leads to comparative statics. For a dynamic analysis one needs a calculus. Information theory offers a calculus (Bar-Hillel, 1955; Theil, 1972), while the measurement results for each moment of time can also be fully appreciated. With best wishes, Loet On 4/9/07, David E.

If so what are they? You seem to have something specific in mind. I would be inclined to define an information system as an information structure which is maintained over time. In the static case (Delta t = 0), we would only have an information structure or a fingerprint of the information system. An information structure is a network or a two-dimensional probability distribution (matrix). (Shannon-type) information is only an uncertainty or a one-dimensional probability distribution. Is this sufficiently abstract to counter your general theory? :-) I agree that it depends of the research question and the research design whether these distinctions are important or not. Best wishes, Loet In contrast, my general theory is designed to define all the possible kinds of links (i.e., relations) between pieces of information, in such a way that we can sort out the important structures. Change over time may or may not be important, depending on the structure, as well as the application of the analysis.

Best regards, David The communication of meaning in social systems pdf-version Abstract The sociological domain is different from the psychological one insofar as meaning can be communicated at the supra-individual level (Sch???tz, 1932; Luhmann, 1984). The computation of anticipatory systems enables us to distinguish between these domains in terms of weakly and strongly anticipatory systems with a structural coupling between them (Maturana, 1978). Anticipatory systems have been defined as systems which entertain models of themselves (Rosen, 1984). The model provides meaning to the modeled system from the perspective of hindsight, that is, by advancing along the time axis towards possible future states. Strongly anticipatory systems construct their own future states (Dubois, 1998a and b). The dynamics of weak and strong anticipations can be simulated as incursion and hyper-incursion, respectively. Hyper-incursion generates ???horizons of meaning??? (Husserl, 1929) among which choices have to be made by incursive agency.

It deals with some h-type indices, and is published in China's multidisciplinary journal: Chinese Science Bulletin. The R- and AR-indices: complementing the h-index Chinese Science Bulletin, March 2007, 52(6), p. 855-863 Bihui Jin, Liming Liang, Ronald Rousseau, Leo Egghe Abstract Based on the foundation laid by the h-index we introduce and study the R- and AR-indices. These new indices eliminate some of the disadvantages of the h-index, especially when they are used in combination with the h-index. The R-index measures the h-core?s citation intensity, while AR goes one step further and takes the age of publications into account. This allows for an index that can actually increase and decrease over time. We propose the pair (h, AR) as a meaningful indicator for research evaluation. We further prove a relation characterizing the h-index in the power law model. In case you do not have access to this journal a reprint can be downloaded from my wegpage.

The focus was on usage statistics and impact metrics. Slides from presentations by Frank Scholze, Johan Bollen and Les Carr are available online. I recommend a download: http://indico.cern.ch/conferenceTimeTable.py?confId=5710&showDate=18-April-2007&showSession=14&detailLevel=contribution&viewMode=plain Statistics have been underutilised to further open access. A parallel issue is how citation metrics have been locked up through ISI and privilege closed access journals. However, potentially, OA metrics could be much more varied (and better). Presentations highlighted the need: - To identify which kinds of stats would be valuable to different groups, such as authors, readers, faculty promotion committees, research evaluation committees, libraries or repository management - For international standardization - To ensure that aggregation, data mining and metrics are collected and analysed in a framework that renders them suitable to providing services. For a moment I would like to focus on services for authors, particularly for junior scholars. This would promote the uptake of OA to pre-prints and post-prints among the younger generation of scholars. Junior authors are very much dependent on ?recognition? of their peers and elders to further their research programmes and careers. Consider the simple metrics that the Social Science Research Network (www.ssrn.com) or Research Papers in Economics (www.repec.org) provide through statistics on abstract views, full-text downloads, subject specific rankings and an overall world ranking (of all authors and papers). A publication in the American Economic Review is, and will be for the foreseeable future, the ultimate accolade for an economist. But short of that, one or more of your (working) papers in a Top 10 list of a subject area is a strong argument in favour of your work. An overall rising ranking (as author, of papers) will support your career. But the ?ranking? has to be recognised and reinforced: SSRN and RePEc are large epistemic networks, in which the papers of junior scholars compete for attention with those of the most senior and prominent scholars. It is also vital that there is only one (authoritative) version of the paper that ?collects? all the metrics. Service provision is about benefits. The future of usage statistics and impact metrics outlined by the OAI5 speakers indicates that the time has come for OA services that will be so attractive that readers, authors and users will find them irresistible.

Then mark, and download die ganze Schmiere. If these are in separate JCRs, then do that for those categories in the separate JCRs into separate spreadsheets, and then merge the spread sheets. The trick is holding down "Control" while clicking your subject categories. Pretty straightforward MS Windows operation.

JAN 2007. p.105-129 SPRINGER LONDON LTD, GODALMING ABSTRACT: Published scientific articles are linked together into a graph, the citation graph, through their citations. This paper explores the notion of similarity based on connectivity alone, and proposes several algorithms to quantify it. Our metrics take advantage of the local neighborhoods of the nodes in the citation graph. Two variants of link- based similarity estimation between two nodes are described, one based on the separate local neighborhoods of the nodes, and another based on the joint local neighborhood expanded from both nodes at the same time. The algorithms are implemented and evaluated on a subgraph of the citation graph of computer science in a retrieval context. The results are compared with text-based similarity, and demonstrate the complementarity of link- based and text-based retrieval.

In Proceedings ELPUB 2007, the 11th International Conference on Electronic Publishing, focusing on challenges for the digital spectrum, pp. 1-11, Vienna (Austria). http://eprints.rclis.org/archive/00009619/ This article compared average citation counts in several different fields for a sample of articles in a sample of OA journals in the Directory of Open Access Journals (DOAJ) . The average citation counts for articles in the OA journals were found to vary across fields. It was concluded that OA research impact varies across fields. No comparison was made with non-OA journals in the same fields. Hence it is impossible to say whether any of these differences have anything to do with OA. Fields no doubt differ in their average number of citations. Journals no doubt differ too. And it is not clear whether the OA journals in each field are the top, medium or bottom journals, relative to the non-OA journals. No conclusions at all can be drawn from this study. Stevan Harnad
