Abstract: A severe criticism against the use of citation indicators for the measurement of a research group’s performance holds that these indicators reflect at least partly the size of the scientific activity in the subfield or topic in which the group works. In this contribution an attempt is made to substantiate this claim within the framework of Price’s theory on the processes of knowledge growth. Empirical evidence is presented that among a number of subfields from the natural and life sciences significant differences exist with respect to Price’s index, and that the citation scores of research groups tend to be high in subfields showing a high value of Price’s index and other characteristics of reference patterns. These findings suggest that groups sharing an intellectual focus with other researchers tend to obtain higher citation scores than groups working more ‘on their own’.

Abstract: Bibliometric analysis is combined with a psychometric analysis of the perceptions which researchers in a community of Dutch fresh-water ecologists have of their professional environment. The results of these two types of analysis converge and can be understood by an exploration of the institutional and intellectual development of the community and the intellectual continuities in the careers of the researchers involved. International developments appear to be taken up in ways which reflect the particular socio-cognitive organization of the national subfield. The article claims that such national subfields of science constitute a strategic research site for social studies of science which is also dixeetly relevant for science policy analysis. It pleads for the employment of a combination of methods in the synchronic and diachronic analysis of the structures of such subfields.

Abstract: For the most part scientific developments in problem fields result in increasing specification of research problems. With respect to the problem of Minima/ Brain Dysfunction, however, the reverse trend can be observed. In the case of the occurrence of behavioural problems related to minimal brain dysfunction, scientific developments resulted in a more diffuse formulation because of the nature of this problem. In the paper co-word analysis methodology is used to study changes in the structure of networks around central terms in this field for the period 1970-1984. It is apparent that central terms in the field arc not able to “funnel the interests” in the field despite the growing number of scientific articles written on the subject.

Abstract: One model for knowledge development is the network interaction model. Insofar as socio-technical networks may have some structural properties, does knowledge development reflect this? The hypothesis that it does may enable us to make some forecasts of science development from a description of the state of a field. One condition necessary for testing this hypothesis is that of adopting a model for these networks. Co-word analysis is such a tool. It gives us key-words networks derived from scientific and technical texts. The author checks for network properties in the area of knowledge development through a case study of Polymer Science and Technology from 1973 to 1978.

Abstract: Review articles in the field of polymer science in the seventies are analyzed in order to check their usefulness in describing at a very low cost the development or the state of the art of a field. Results are compared with those obtained through a quantitative study of scientific articles published at the same time in the field. Review articles can be regarded as defining a research programme attempting to link together two networks: polymer properties - as being desirable from market Considerations - and polymer structure - as being analyzable by means of academic science, through three kinds of “translation” strategies. If we thus define a research programme in terms of the mobilization of networks, it is possible to say of review articles that they provide a good representation of the development of networks of problems whose evolution they sketch.

Abstract: Titles of 925 conference papers contained in the first l~en International Teletraffie Conferences (1955-1983) are analyzed in terms of word distributions. The aim is to determine how information about changing word frequencies and word patterns relates to the kind of information gained through the more traditional approach of intellectual history. Additionally, we consider what each approach can reveal about the information flows involved in the production and utilization of knowledge in teletraffic. In terms of methodology, the goal of this dual approach is to understand how the analysis of word and document structures can be used both as a seientometrie tool and as a tool for historical research. We also comment more generally on the significance of conferences as an object for scientometric analysis, particularly with respect to the emergence and growth of the engineering and industrial sciences.

Abstract: A new bibliometrie method is proposed for representing links between subfields as defined by a classification scheme. The frequency of co-occurrence of articles from different subfields in selected journals is used for measuring the degree of relatedness between these subfields. The results of such quantitative analysis could be compared to the thee topology of the classification network established in a qualitative analysis. The method is applied to describe the internal links within the field of condensed matter physics using the 1984 Physics Abstracts database. A distinction is made between experimental and theoretical links on the basis of treatment codes assigned to journal articles. The links deseribed by cluster analysis axe matched against the cross-reference network of the International Classification for Physics.

Abstract: This paper discusses the possibility to represent scientific development by ‘second-order networks’ in different modalities. In particular, a specific modality structured by subfield-to-subfield relations is presented. By constructing such ‘co-subfield maps’ for successive periods of time, we were able to describe the changing subfield relations within the field of chemical engineering. In this way, dynamical processes in the development of a field as a whole can be revealed. Advantages and disavantages as compared to co-eitatio n and co-word mapping techniques are discussed and the importance of developing combined techniques is stressed.

Abstract: A sample of “Citation Classics” in three scientific fields was studied to uncover citing motivations. The classics were classified into basic research, methods and reviews. Number of citations received per classic, number of authors, and age of classic per category and scientific field were the parameters studied. Journals and countries accounting for the highest incidence of classics were examined. A striking parallelism was found in the parameters applied to the categories in the scientific fields Studied. This parallelism suggests similar citing habits of scientists in the fields studied which should be reflected in the structures of Science obtained through citation grounded bibliometric models.

Abstract: dely available to researchers that they have become potentially an important source of time series estimates of the growth of scientific literature. This paper uses the GEOREF s database in such an application to estimation of the growth of geoscience. It is found by comparison with studies previously done from the hardcopy equivalents of GEOREF s that the computer-derived time series can achieve results similar to their equivalents and do this more efficiently, more inexpensively and more comprehensively. Examples are given for geoscience as a whole, and for the literature related to several mineral commodities: iron ore, lead ore, nickel ore, petroleum and natural gas, radioactive minerals and ores, and zinc ore.

Abstract: The beginning and early spread of the world-wide epidemic of acquired immunodeficiency syndrome (AIDS) has been paralleled closely by a rapidly expanding literature concerned with many aspects of the disease. In order to assess the growth of the AIDS literature, a quantitative analysis was conducted focusing on the number of articles, the number of journals contributing, the number of languages used, and the number of countries of origin of publications over time (a bibliometric study). The growth of the popular literature was also studied. Three online databases - MEDLINE, Magazine Index, and the National Newspaper Index - were examined from 24 September 1982 (the datea the Centers for Disease Control first adopted the name ‘acquired immunodeficiency syndrome’) through the end of 1986 for the popular literature and through the end of 1987 for MEDLINE. A survey of the MEDLINE file showed that by the end of 1987, twenty-five languages were represented in articles from fifty-four countries published in 1170 different journal titles.

Abstract: Most of the scientific and technical databases contain codes. These codes divide the area of the database field in subfields. These divisions can be used to map automatically the research network of a subject, and to provide its main research poles. The present paper explains the methodology, and applies it to Chemical Abstracts, and to the analysis of the research production of various academic institutions. The method is general and can be used with other databases such as Inspec, WPI-WPIL, etc...

Abstract: The article deals with the statistical problem of the difference between the mean citation frequencies of two sets of papers required to be significantly different. An analysis of citation data indicated that, as a first-order approximation, (1) The relative spread due to a short observation interval is independent of the long-term citation frequency and (2) the relative spread in long-term citation frequencies of different papers from the same author is independent of the mean citation score for the papers by that author. As a rule-of-thumb, these two sources of variance can be characterized by standard deviations of a ratio (factor) of 2 and 3, respectively. By applying these results to citation data published in the literature, it is shown that sometimes statistically unjustified conclusions have been drawn in the past.

Abstract: In this study an attempt to examine the dependence between the productivity of core journals and the shape of the distribution curve in the upper section is made. For this purpose, the impact of the core journal productivity increase over an extended time interval was investigated. As a referent point in relation to which the changes were followed, equalized inverse relationship between the core and periphery in terms of the number of journals and the number of papers published in them in a given subject field has been hypothesized. The degree to which a particular set of data conforms to that relationship expressed as #, is taken as an indicator of the changes in the core/periphery relation. The applicability of Lotka’s exponent in the journal productivity context is also discussed.

This article provides an overview of the various arguments which have been made, and reports that recent reorganization in the on-line installations [SciSearch] should make it possible to circumvene one of the major sources of error.

Abstract: The technique of sampling a department’s k best publications as a means of assessing the quality of its research performance is investigated. It is shown that this procedure confounds merit with departmental size, and leads to a substantial overestimation of the research achievement of larger departments. The 1985-86 evaluation of research performance conducted by the University Grants Committee of the United Kingdom contained a sampling error of this kind.

Abstract: To compare citation history and contextual ‘importance,’ eleven highly cited axticles, 4 slowly aging (Type 1) and 7 quickly aging (Type 2), were ranked using an aggregate citation context measure, the Mean Utility Index. Based on citations in late (PY 6 & 7) source articles, ‘methods’ papers consistently ranked higher than papers cited for research results and theoretical implications, and Type 1 methods papers ranked above all Type 2 papers. A Type 1 paper representing an important theoretical concept could not be distinguished from Type 2 papers using citation context alone.

AS such, the selection is not randomised and there can not be any empty source. A source approach has been presented here with minimum of assumptions and conditions. An equation of scattering distribution is derived. If there are M sources and N items, the probabifity or the relative frequency of the sources with ith group items is given by 141(0 KM-i = CM -i exp(-rM§ ~M]. Suggestions and procedures for experimental verifications have been sketched. Derivations from Bose-Einstein statistics with Gibrat’s law a 2 have been discussed and compared.

Abstract: Some theoretical connections with Bradford’s law of scattering of articles in jgumals have been noted to substantiate the completely empirical linear formula, R(r) = a.r-b where r is the rank of a class of journals in increasing productivity, R is a typical function, called ‘mean relative scatter’ (MRS), of the class rank r, a and b are arbitrary constants. It is also shown that an exponential formula can be transformed to the linear one, thereby explicating certain constants and co-efficients of Bradford’s formula and the proposed one.

Abstract: Is is shown, using rigorous statistical tests, that the number of journals (J) carrying p papers in a given subject can be expressed as a simple power law function J(p) = K p’r, K and y being constants. The standard maximum likelihood method of estimating 3’ has been suitably modified to take acoount of the fact that p is a discrete integer variable. The parameter 3’ entirely characterises the scatter of articles in journals in a given bibliography. According to a dynamic model proposed earlier by the author, 3’ is a measure of the relative rowth rates of papers and journals pertaining to the subject.
