Summary  

We apply an old method for constructing points-and-lines configurations in the plane to study some recent questions in incidence geometry.

Abstract  

This paper examines the patterns of multiple authorship in five information systems journals. Specifically, we determine the distribution of the number of authors per paper in this field, the proportion of male and female authors, gender composition of research teams, and the incidence of collaborative relationships spanning institutional affiliations and across different geographic regions.

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  

This paper presents the results of an examination of a selection of published European evaluations. The incidence of quantitative and scientometric approaches has been reviewed and an assessment made of their contributory role in each evaluation. The various approaches have been broadly categorised according to the type of data they draw upon, and by the issues they attempt to address. The author analyses such approaches with regard to the degree of success in meeting the objectives of the evaluation. In the light of this some likely future trends are suggested.

Abstract  

In accordance with high incidence of AIDS cases, there is an epidemic growth of its literature. This unprecedented growth of literature calls for serious scientometric study. Such a study will not only help the scientometrists, information scientists, but also will be very useful to the related research workers. With this in view an attempt has been made to analyse AIDS literature published during the period 1976–1986 to identify its international channel of communication, medium of communication, contributing countries, authorship trends etc. This study is based on data printed in a source document entitledCollected Papers on AIDS Research, 1976–1986 published by BIOSIS which is a retrospective bibliography incorporating valuable references to research on AIDS from 9,000 source titles monitored in BIOSIS data base. The findings of this study have also been compared to those ofWyatt andSelf, Filardo andLancaster.

A case study for ages more prone to death

Scientometrics
Author: Ahmed F. Siddiqi

Summary  

A person can die at any age. It is an omni-spoken common saying. Is it really true? Are all ages equally prone to die? Does there exist some predictable pattern that may conjecture the incidence of death? These are the questions that are attempted here in this article. Literature is replete with cohort dependant age distributions and pyramids that focus, and are adjusted, primarily for the living persons. The current article is using a cohort free group of people and focuses exclusively on age at death to rummage for some pattern in these ages. A statistical investigation is made of the life span of human beings of previous two centuries. The life span, or age, distribution is revealed to be a quadric modal in nature, refuting the prevailed myth that all ages are equally susceptible to death.

Abstract  

A Multidisciplinary Research Programme (MRP) is being developed since 1989 in the Universidad Complutense de Madrid (UCM), Spain, to support cross-disciplinary research projects. This paper analyses the incidence of interdisciplinarity in the UCM scientific publications over the period 1990–96 and tries to determine the success of the Programme at fostering cross-disciplinary research. Interdisciplinary in the UCM is measured through the collaboration of authors from different institutional addresses within the UCM, both in scientific publications and in research projects. Publications jointly signed by the different teams that collaborate in the projects were identified as an indicator of the success of the Programme in integrating disciplines. Interdisciplinary collaboration within the UCM showed an upward trend over time. Publications of MRP groups showed a higher interdisciplinary collaboration rate than the rest of the UCM (17% vs. 9%). Dramatic repercussions of the Programme were not expected due to its limited magnitude, but it worked as a catalyst, enhancing interdisciplinary relations within the UCM. The interest of such a programme is supported by its effects, both direct effects on granted teams and indirect on the whole UCM community.
