- 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
- Bradford distributions describe the relationship between 'journal productivities' and 'journal rankings by productivity'. However, different ranking conventions exist, implying some ambiguity as to what the Bradford distribution 'is'. A need accordingly arises for a standard ranking convention to assist comparisons between empirical data, and also comparisons between empirical data and theoretical models. Five ranking conventions are described including the one used originally by Bradford, along with suggested distinctions between 'Bradford data set', 'Bradford distribution', 'Bradford graph', 'Bradford model', and 'Bradford's law'. Constructions such as the Lotka distribution, Groos droop (generalised to accomodate growth as well as fall-off in the Bradford log-graph), Brookes hooks, and the slope and intercept of the Bradford log graph are clarified on this basis

- Abstract
- Numerous attempts have been made to validate the use of citations as an evaluation method by comparing it with peer review. Unlike past studies using journals, research articles or universities as the subject matter, the present study extends the comparison to the ranking of individual scholars. Results show that citation ranking and expert judgement of communication scholars are highly correlated. The citation methods and the expert judgement method are found to work better in smaller research areas and yield more valid evaluation results for more prominent scholars

- Abstract
- A formula for the ranking of scientists based on diachronous citation counts is proposed. The paper generalises the fact that the citation generation potential (CGP) is not the same for all papers, it differs from paper to paper, and also to a certain extent depends on the subject domain of the papers. The method of ranking proposed in no way replaces peer review. It merely acts as an aid for peers to help them arrive at a better judgement.

- 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
- Investigates the characteristics of Journal Citation Reports (JCR) through the study of the Science Citation Index (SCI). Other criteria for evaluating a journal are also discussed. The compilation process of SCI data, and the characteristics, applications and limitations of SCI are studied. A detailed description of JCR is provided including: journal ranking listing, citing journal listing, cited journal listing, subject category listing, source data, impact factor, immediacy index, cited half-life and citing half-life. The applications and limitations of JCR are also explored. In addition to the criteria listed in JCR, the size, circulation and influence of journals are also considered significant criteria fir evaluation purposes

- Abstract
- A simpler model is proposed for estimating the frequency of any same-frequency words and identifying the boundary point between high-frequency words and low-frequency words in a text. The model, based on a 'maximum-ranking method', assigns ranks to the words and estimates word frequency by a formula. The boundary value between high-frequency and low-frequency words is obtained by taking the square root of the number of different words in the text. This straightforward model was used successfully with both English and Chinese texts

- Abstract
- Describes a study using citation analysis to select journals that could be used in the veterinary medical field. The study determines the principal journals to which a veterinary medical library should subscribe, thus obtaining the highest possible utility of materials. By using a database of 105 journals for a period of five years (1982-86), citation data were applied on the Bradford bibliography and Bradford-Zipf distribution to determine the ranking of journals in the field and the "core journals". Reports the results of the study which discovered that the Bulletin of Animal Health and Production in Africa is the most cited journal with 305 citations, and the core journals were eight in number, having 1,067 citations representing 66.2 per cent of the total citations.
