Abstract  

Journal citation impact factors, which are frequently used as a surrogate measure of research quality, do not correlate well with UK researchers" subjective views of the relative importance of journals as media for communicating important biomedical research results. The correlation varies with the sub-field: it is almost zero in nursing research but is moderate in more “scientific” sub-fields such as multiple sclerosis research, characterised by many authors per paper and appreciable foreign co-authorship. If research evaluation is to be based on journal-specific indicators, then these must cover different aspects of the process whereby research impacts on other researchers and on healthcare improvement.

Abstract  

This study examines patterns of authorship in nineteen Egyptian journals of agricultural science. Multiple authorship was found to be the predominant trend in the field and co-authored papers accounted for some 79 percent of the sample. The most common form of multiple authorship involved three people. Considerable variation was found among sub-fields and co-authorship was found to be most common in social-science related agricultural disciplines. The author found no significant differences in patterns of collaboration in the agricultural sciences in Egypt and two the other developing countries for which comparative data was available, India and Pakistan.

Abstract  

This article describes ways of automatically generating 15 kinds of personal profiles of authors from bibliographic data on their publications in databases. Nicknamed CAMEOs, the profiles can be used for retrieval of documents by human searchers or computerized agents. They can also be used for mapping an author's subject matter (in terms of descriptors, identifiers, and natural language) and studying his or her publishing career. Finally, they can be used to map the intellectual and social networks evident in citations to and from authors and in co-authorships.

Abstract  

It was tested whether the publication rate of scientists as a rough measure of their eminence, influences their stratification. The stratification is reflected in cooperation, in co-authorships, in the structure of the citations and in the distribution of publications among the various problem areas of a scientific discipline. The findings of these investigations was discussed as a contribution to the dispute among authors who accept or reject the Ortega hypothesis which states that the research done by average scientists substantially contributes to the advance of science.

Abstract  

Collaboration and cross-disciplinarity are important features in autoimmune disease research. Taking co-authorship as an indicator for research collaboration, for selected European countries it was found that 91% to 99% of all publications are based on collaboration. International collaboration affects about 27% of all publications. Small countries like Sweden and Finland pursue international collaboration more intensively than larger countries like Germany or the UK. Different collaboration strategies were found for nationally co-authored papers, for instance, Germany seems to focus more on intra-departmental collaboration, while France and Italy have stronger inter-institutional links. About 54% of all publications are based on cross-disciplinary

Abstract  

A bibliometric online technique is applied on data from the INSPEC bibliographic file to describe some aspects of Moravcsik's publication activity (co-authorship, source journals, etc.). Separately, a co-occurrence method is used to represent the subject structure (the main topics and their links) of his papers in physics. The principle underlying this method is to develop a network based on common appearances of classification subdivisions (headings) as well as of controlled terms in Moravcsik's document records. The results, in the form of line and point graphs, give a global picture of Mike Moravcsik's research profile in physics.

Abstract  

The paper analyses the output of the publication data of an Indian laboratory in the field of physics inSCI and nonSCI covered Indian and foreign journals, processes developed and Indian patents filed during the period 1965–82 to find out the pattern of productivity. Looks at the journals wherein the laboratory scientists publish. Also points out the sub-areas of physics in which the laboratory scientists have published maximum papers and also mentions about the pattern of scientific co-authorship in the research work. Correlation coefficients between input variable (manpower and budget) with output variables (number of papers published, processes developed and Indian patents accepted) have been calculated.

Abstract  

The publications by the Spanish scientists recorded in eight international databases in the years 1978 and 1983 are retrieved. Science indicators able to give a perception of the scientific productivity, the institutions involved, the habits of publishing in foreign or domestic journals and co-authorship are presented. The changes observed in these indicators in the two analysed years are examined and the trend in the evolution of the Spanish science is shown. The time delay in recording items by the databases and coverage of the Spanish journals are also studied.

Abstract  

During the period 1985–1995 Daniel Koshland was Editor-in-Chief of the journal Science. As such he exerted a huge influence on all aspects related to content and lay-out of the journal. This study compares Science’s bibliometric characteristics between three periods: a pre-Koshland (1975–1984) period, the Koshland period (1985–1995) and the post-Koshland period (1996–2006). The distributions of document types, the country/territory and institutional distribution of authors, co-authorship data and disciplinary impact measured by subject categories of citations are studied. These bibliometric characteristics unveil some of the changes the journal went through under the leadership of Daniel Koshland.

Abstract  

Opinions in the literature on the possible relationship between co-authorship and number of citations vary. This paper contributes to the debate with a further analysis of the subject, taking account of the number and quality of citations found for multi-(author, institution, country) and single-authored papers. The study is based on the scientific production of ten Carlos III University of Madrid departmental areas between 1997 and 2003 as reflected in the ISI Web of Science, and the number of times the respective papers were cited between 1997 and 2004. Univariate multifactorial analysis of variance (ANOVA) was used to verify the relationship between multi-authorship and visibility. The correlation between multi-institutional and multi-national authorship and the quartile of the citing journals was analyzed with correspondence analysis. The results show that while multi-institutional and multi-national authorship raise the number of citations, co-authorship and number of citations are unrelated. Correspondence analysis failed to show any correlation between the quartile of the citing journal and multi-institutional or multinational authorship, but did reveal a relationship between citing journal quartile and departmental area.
