- Abstract
- University librarians continue to face the difficult task of determining which journals remain crucial for their collections during these times of static financial resources and escalating journal costs. One evaluative tool, Journal Citation Reports (JCR), recently has become available on CD-ROM, making it simpler for librarians to use its citation data as input for ranking journals. But many librarians remain unconvinced that the global citation data from the JCR bears enough correspondence to their local situation to be useful. In this project, I explore the correlation between global citation data available from JCR with local citation data generated specifically for the University of British Columbia, for 20 subject fields in the sciences and social sciences. The significant correlations obtained in this study suggest that large research-oriented university libraries could consider substituting global citation data for local citation data when evaluating their journals, with certain cautions.

- Abstract
- Context analysis is a new method for appraising a body of publications. the process consists of creating a database of attributes assigned to each paper by the reviewer and then looking for interesting relationships in the data. Assigning the attributes requires an understanding of the subject matter of the papers. Presents findings about one particular research field, Management of R&D at the Section Level. The findings support the view that this body of academic publications does not meet the needs of practitioner R&D managers. Discusses practical aspects of how to apply the method in other fields

- Abstract
- Reports results of a bibliometric study of the literature of Qigong: a relaxation technique used to teach patients to control their heart rate, blood pressure, temperature and other involuntary functions through controlles breathing. All articles indexed in the MEDLINE CD-ROM database, between 1965 and 1995 were identified using 'breathing exercises' MeSH term. The articles were analyzed for geographical and language distribution and a ranking exercise enabled a core list of periodicals to be identified. In addition, the study shed light on the changing frequency of the MeSH terms and evaluated the research areas by measuring the information from these respective MeSH headings

- Abstract
- Examines the use of networked information sources in scholarly communication. Networked information sources are defined broadly to cover: documents and images stored on electronic network hosts; data files; newsgroups; listservs; online information services and electronic periodicals. Reports results of a survey to determine how heavily, if at all, networked information sources are cited in scholarly printed periodicals published in 1993 and 1994. 27 printed periodicals, representing a wide range of subjects and the most influential periodicals in their fields, were identified through the Science Citation Index and Social Science Citation Index Journal Citation Reports. 97 articles were selected for further review and references, footnotes and bibliographies were checked for references to networked information sources. Only 2 articles were found to contain such references. Concludes that, although networked information sources facilitate scholars' work to a great extent during the research process, scholars have yet to incorporate such sources in the bibliographies of their published articles

- Abstract
- It is possible, using ISI's Journal Citation Report (JCR), to calculate average impact factors (AIF) for LCR's subject categories but it can be more useful to know the global Impact Factor (GIF) of a subject category and compare the 2 values. Reports results of a study to compare the relationships between AIFs and GIFs of subjects, based on the particular case of the average impact factor of a subfield versus the impact factor of this subfield as a whole, the difference being studied between an average of quotients, denoted as AQ, and a global average, obtained as a quotient of averages, and denoted as GQ. In the case of impact factors, AQ becomes the average impact factor of a field, and GQ becomes its global impact factor. Discusses a number of applications of this technique in the context of informetrics and scientometrics

- Abstract
- Reports results of a bibliometric study of the authorship characteristics of articles published in 4 major information science periodicals: JASIS, Information technology and libraries, Journal of information science, and Program. The aim was to determine the details of their authors, such as: sex, occupation, affiliation, geographic distribution, and institutional affiliation. A total of 163 articles published in 1993 and written by 294 authors were analyzed. Results indicate that: men (206 or 70%) publish 3.0 times more articles than women (69 or 23,5%). Schools of library and information science contributed the most authors. The majority of authors came from the USA (148 or 50,3%), with the Midwest region claiming the largest share (110 or 25,0%). Academic libraries (110 or 37,4%) account for the major share of library publication. 12 schools of library and information science, in the USA, contributed 32 authors (50,0%) and assistant professors (25 or 39,1%) publish the most in these library schools. Male school of library and information science authors publish 1,6 times more than their female counterparts

- Abstract
- Introduces the standard impact factor for particular fields of science (Ig) and the relative impact factor K for scientific journals. The technique for the calculation of the standard impact factor for a field is an inherent part of a methods which allows a cross field evaluation of scientific journals. This method for evaluating scientific journals elaborated in 1988 was aimed at the analysis of Russian journals covered by the SCI database; it was also used for chemical journals and for journals in the life sciences

- Abstract
- Much effort has been done to develop more objective quantitative methods to analyze and integrate survey information for understanding research trends and research structures. Co-word analysis is one class of techniques that exploits the use of co-occurences of items in written information. However, there are some bottlenecks in using statistical methods to produce mappings of reduced information in a comfortable manner. On one hand, often used statistical software for PCs has restrictions for the amount for calculable data; on the other hand, the results of the mufltidimensional scaling routines are not quite satisfying. Therefore, this article introduces a new iteration model for the calculation of co-word maps that eases the problem. The iteration model is for positioning the words in the two-dimensional plane due to their connections to each other, and its consists of a quick and stabile algorithm that has been implemented with software for personal computers. A graphic module represents the data in well-known 'technology maps'

- Abstract
- Discusses evaluation techniques as an integral part of science with the emphasis on evalution for policy purposes. Outlines early attempts to validate the use of biliometric indicators. Concludes that: best results are obtained by applying a variety of methods simultaneously; reliable results can be obtained from citation analysis for purely scientific subfields such as physics; and citation analysis tends to give unreliable results for technological subjects. Concludes that bibliometrics as a technique for determining policy should never be used on its own. Describes an evaluation method used for selecting research projects for financial support, as applied by STW, the technology branch of the Netherlands' research council, NWO

- Abstract
- Data visualization techniques have opened up new possibilities for science mapping. To exploit this opportunity new methods are needed to position tens of thousands of documents in a single coordinate space. Describes a general framework for achieving this goal involving hierarchical clustering, ordination of clusters, and the merging of ordinations into a common coordinate space. Presents the SciViz system as one particular implementation of this framework

- Abstract
- We use a social network approach to examine how work and friendship ties in a university research group were associated with the kinds of media used for different kind of information exchange. The use of e-mail, unscheduled face-to-face encounters, and scheduled face-to-face meetings predominated for the exchange of 6 kinds of information: receiving work, giving work, collaborative writing, computer programming, sociability and major emotional support. Few pairs used synchronous desktop videoconferencing or the telephone

- Abstract
- The relative impact of local research units is obtained by dividing the observed number of citations to their publications by the expected number of citations. It is argued that the expected citation rates used in the standard method cannot lead to relevant bibliometric scores for specific research topics. Extracting information about quality of research with the standard method is, therefore almost impossible. The existence of empirical relations between the number of citations and the number of publications for scientific disciplines and for journals, leads to alternative ways to determine relative impact. Hereby, refernce data are taken from within a given research topic. Only observed citation and publication (activity) patterns for research topics are taken into account for calculating bibliometric scores. The new methods are not restricted to ISI-publications. The rsulting bibliometric scores can contain information about the quality of research, and lead to different rankings than those obtained with the standard methods, although the same citation and publication data are used
