Abstract  

This study covers a ten-year period, 1990-1999, of the publishing careers of nine authors who appear in the top-20 most productive authors in the field of ophthalmology. In this paper we discuss findings from a study of the publishing careers of elite researchers in the field of ophthalmology. The paper highlights the extent and nature of the journals in which these elite researchers publish their work. Data derived from the study include indications of multidisciplinary involvement or 'work-space' interests, publication characteristics, and collaborative engagement with others. We provide insights into the workings of author productivity, characteristics of papers such as numbers per paper of pages, references, and authors, and initial findings about their collaboration patterns. These findings, showing (ir)regularities or patterns in publishing careers, may be of interest to researchers and practitioners because they provide a view that might not otherwise be apparent to the field or to authors themselves.

This paper is the continued study on age structure of scientific collaboration in Chinese computer science. Based on an extended database a new method is used to analyze the nature and preference of collaboration. Observed values of two- three- and four-dimensional collaboration were compared respectively with their expected values. Investigation covered co-authors" combination patterns, name permutations in their papers, especially the age of the first author.

Abstract  

The biological arms race could have been considered a closed chapter in the Cold War history. However, the growth of different terrorist groups and organisations has increased the threat of biological weapon (BW) use. The goal of this pilot scientometric project was to trace changes in biodefense research and the activities of its main players, Russia and the US. Data were collected from the SCI via the Dialog information system for1991-2000, the period covering the post-soviet era. In-depth content analysis was performed on selected papers from the 2870 publications identified as BW-related. During the period examined, the publication flow increased by 250 percent. The main contributors to this literature were shown to be the US, Russia, UK, France and Germany. The results presented in this paper are of interest to security analysts (following the attacks in the US of 11th September 2001), to public health care policy researchers and to politicians.
