We give an overview of the main data of a publication-citation matrix. We show how impact factors are defined, and, in particular, point out the difference between the synchronous and the diachronous impact factor. The advantages and disadvantages of using both as tools in research evaluation are discussed.

The total scientific output of mainstream articles for the 15 most productive African countries for the period 1991 to 1997 was 45,080, with South Africa and Egypt publishing 15,725 and 10,433, respectively. The productions of these two top ranked countries varied little from 1991-1997 while others such as the Maghreb countries increased between 75-102%. Total contributions were mainly in the fields of Clinical Medicine (36%), Biology (17%), Chemistry (14%), and Biomedical Research (12%). Papers in international collaboration were overriding in Biomedical Research, Biology, Earth and Space Science, and Physics. Institutions in the US were the principal collaborators followed closely by those in France.

Increasing importance is being given to international scientific activities, especially with regard to developing countries. In the present paper, an analysis is made of the studies published by Mexican institutions in coauthorship with foreign colleagues between 1980 and 1990, as registered in mainstream journals. Different characteristics of the collaboration are described, such as research areas, countries and institutions involved, of interest to Mexican policy makers and scientists, as well as to foreign governments and international organizations sponsoring cooperative agreements with Mexico.

Impact factors, publication-citation patterns and growth dynamics were analyzed for the Latin America and the Caribbean journals covered by the Science Citation Index (SCI) and Social Science Citation Index from 1995–2003. Two main journal groups were identified: those publishing mainly in English with substantial contributions from outside the region, and those publishing in local languages, principally by the local community and on subjects of local interest. We found little inter-citation among the local papers while the highest number of citations by extra-regional authors was to papers published in English. Quantitative indicators show that LA-C journals are better positioned in the mainstream literature than ever before.

The publication and coauthorship patterns between 1980–1994 of 15 highly productive Mexican scientists were studied in relation to their 565 research papers involving only national institutions and 232 published with colleagues from abroad. Three scientists were selected from each of the following areas: Biomedicine, Chemistry, Physics, Astronomy and Astrophysics and Geosciences. Parameters studied were: vehicles used for publication; document types; number of authors; collaborating countries; and author position. The results are discussed in relation to Mexicos peripheral position with regard to the scientific center, and the increasing internationalization of Mexican science.

An analysis carried out on the 4,326 periodicals in the social sciences included in the mostrecent 1991 printed edition of the UNESCO DARE database showed that 64% of the worldsproduction is published by High Income Economy countries (IEC). Only 0.7% of Low IECjournals in the UNESCO database were also present in the Social Sciences Citation Index (SSCI)for the same year while corresponding figures for the Middle and High IEC were 2.3%, and97.0%, respectively. With the notable exception of the United States, all countries had fewerjournals in SSCI than in UNESCO database.

Three databases were used to analyse documents written in collaboration between Latin America and Spain from 1984 to 1988, and to determine how the choice of databases affects results. A total of 402 documents was regis tered in the Science Citation Index while 149 documents were found in two Spanish databases, ICYT and IME, covering national journals in science and technology, and medicine, respectively. Studies relating to fields of basic research were more likely to be published in the Journals included in SCI while research in applied fields tended to appear in the national Journals covered by the Spamsh databases. Our re sults suggest that authors of collaborative papers prefer to publish in mainstream Journals rather than in Spanish jour nals, even those covered by SCI.

A total of 2192 articles published in the international literature with UNAM (National University of Mexico) first author affiliation and registered by the CICH (Centro de Iformación Científica y Humanística) BIBLAT database from 1978-mid-1987 were included in our analysis. Distribution of articles according to the main subject areas of the 692 different journal titles used was as follows: Physics 24.1%, Medicine 19.7%, Biology 19.4%, Chemistry 9.7%, Engineering 8.9%, Exact Sciences 7.3%, Geosciences 4.7%, Psychology 0.96%, Agrosciences 0.27%. Thirty-seven percent of articles were published in journals with a known impact factor for 1987 of ≤1, 46.1% (920) in journals within the range of >1–3 average citations/article and only 16.4% (327) in those titles with a factor >3. Fifty-four percent (1082) of studies appeared in journals whose total citation count for 1987 was ≤5000; 7.3% (146) in journals cited >50,000 times in that same year. UNAM scientists therefore as a group tend to publish in journals whose articles are not frequently cited in subsequent publications thus limiting their impact and visibility in the international scientific literature.

The publication and citation patterns of the Mexican community in elementary particle physics (MEPP) were determined by bibliometric analysis of the scientific production and citations registered in the SPIRES-HEP system from 1971 to 2000. All papers, both citing and cited, were classified as theoretical, phenomenological or experimental according to the type of study carried out and citing papers as local (Mexican) or foreign. The growth dynamics of the citation patterns over the thirty-year period was also studied. Results show that the Mexican scientific community in EPP follow the pre-publication and pre-citation communication patterns typical of a Big Science field.

SummaryWe present the results on the relationship between the bonding number (the number of links among the authors of an article) and a measure of group cohesiveness on a Likert-type scale in three research areas, Biotechnology, Mathematics and Physics, at the National University of Mexico (UNAM). We found a difference between disciplines with regard to group size, and although there is little difference between disciplines in cohesiveness, results suggest that there is a direct relationship between the level of cohesiveness and the bonding number in Physics and Biotechnology, but not in Mathematics where the groups are much smaller.
