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 Mexico's peripheral position with regard to the scientific center, and
the increasing internationalization of Mexican science.
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.
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.
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 world'sproduction 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.
A comparative analysis carried out on the literature citation characteristics of two sets of Mexican research documents produced in the veterinary field-the undergraduate thesis and the research journal article-revealed distinct patterns of literature usage on the part of the authors. It is suggested that the differences reflect the relative qualities of the research undertaken by two populations with distinct research competence and experience.

Summary We 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.

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.

A detailed analysis of the research carried out in Mexico in the physics specialty of particles and fields (MPPF) reveals
the way the current production and citation patterns evolved over a period of 60 years. The basis for the analysis were the
publications and citations registered in the Stanford Public Information REtrieval System—High Energy Physics (SPIRES) from 1970 to 2007. The historical coverage afforded by the Science Citation Index provided supplementary data from 1948 to 1979. Papers were classified into five research types: theoretical, phenomenological,
experimental, cosmological, and other, while citations were identified as coming from: published or unpublished sources. Results
show that the development of MPPF emerged from traditional theoretical and phenomenological research and that the most notable
changes taking place in production and impact are associated with the community’s involvement in more productive and more
internationally visible research practices, characteristic of large international collaborations, leaders in experimental
physics and in the authorship of review papers.

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.
