Abstract  

This paper studies cooperation patterns in Spain between science history researchers by analysing co-authorship in the scientific publications of the Social Science Citation Index (SSCI) and the Science Citation Index (SCI) databases.

Abstract  

This study is an analysis of six years of Spanish bibliography retrieved from INSPEC and COMPENDEX. The quantitative evolution of the scientific activity by years and Institutions, the recent tendencies to publish in foreign journals, as well as to have the papers signed by more authors are followed. The most frequently used journals are ranked according to their impact factor and subject. Some hypothesis are formulated and tested, trying to find a relationship between the growth of the Spanish scientific activity and its quality.

Abstract  

U, Th and Ra isotopic activities have been measured in water and sediment samples collected over three years from the Guadalquivir river channel (South of Spain). The study of the radioactivity levels and activity ratios evolution in space and time has provided information on the behavior of the radionuclides mentioned above in the estuarine and non-estuarine zones of the river.

Abstract  

The presence of224Ra and226Ra in waters from an estuarine system which surrounds a phosphate fertilizer complex (southwest Spain) has been studied. The high activities obtained confirm that an important radiological impact from such industrial complex on its close environment is being produced. The influence of tidal oscillations and seasonal conditions on activity concentration has also been investigated.

Abstract  

The occurrence of anomalous enhancements of U-isotope activities in the surrounding environment of a phosphate fertilizer factory complex at the southwest of Spain has been established. It seems that significant amounts of U, released by such industries, are being accumulated in the environment, which may substantially contribute to the collective radiation dose received by the local population.

Abstract  

The scientific production measured by the number of mainstream joint publications, resulting from the cooperative research efforts between Chile and Spain, considering disciplines, application field, type of journal, impact factor, and research institutions involved, was analyzed for the 1991-2000 period. Databases from several institutions, such as the Institute for Scientific Information (ISI) in USA and other national organizations, were employed to quantify the number of publications and to determine the profile of the mutual-collaboration research groups of both countries. It was possible to establish the strong points of the mutual work in some disciplines and the formation of a critical mass of researchers, showing that the scientific cooperation between countries of emerging-economies, like Chile, and developed nations, as Spain, is possible and leads to mutual benefits.

Abstract  

Publications and author cocitations in library and information science in Spain during the period from 1985 to 1994 were analyzed as a measure of the structure, specificity and composition of research fronts in this country. A cocitation matrix developed from an ad hoc database was subjected to cluster analysis, multidimensional scaling and principal components analysis. The resulting cocitation maps identified specific areas of research and their knowledge bases. We inferred the degree of consolidation of the discipline of library and information science, and of the subdisciplines informetrics, librarianship and university affiliation, from the research activities revealed. In this respect, the conclusions from the study show the existence of several research fronts in Spanish literature the contents of which are in most cases difficult to compare with those in other countries. A lesser degree of maturity of research in this field is shown.

Abstract  

We present some results of an evaluation of research performance of Spanish senior university researchers in Geology. We analyse to what extent productivity of individual researchers is influenced by the level of consolidation of the team they belong to. Methodology is based on the combination of a mail survey carried out among a defined set of researchers, and a bibliometric study of their scientific output. Differences among researchers have been investigated with regard to team size and composition, patterns of publication in domestic and foreign journals, productivity, co-authorship of papers, and impact of publications. Results indicate that not belonging to a research team represents a handicap at the time of publishing in top international journals. Researchers belonging to consolidated teams are more productive than their colleagues in non-consolidated teams, and these in turn more than individuals without team. Team size does not appear to be as important for scientific productivity as the number of researchers within the team that reached a stable job position. Analysis of the impact factor of journals has not revealed differences among researchers with regard to the visibility of their papers.

Bibliometric analysis of publications of Spanish pharmacologists in the SCI (1984–89). Part II

Abstract  

During the period 1984–89 Spanish pharmacologists published 344 papers (44.3% of their total scientific production) (Science Citation Index, CD-Edition) in journals classified by theSCI in subfields different from Pharmacology & Pharmacy. Distribution by institutions, geographical regions, journals, subfields and research levels are presented. The Normalized Journal Position (NJP) is introduced as indicator of the expected impact in each subfield. Results are compared with those of the analysis of the production of Spanish pharmacologists in the Pharmacology & Pharmacy subfield, presented in a previous paper. Some of the features detected are common to both areas, such as: increasing trend in the productivity over years, irregular geographical distribution with three regions as major producers, or university as main producer institution. Special features of the extra-Pharmacology area are also pointed out: irregular growth of publication number over years, high dispersion of publications in journals and subfields, high collaboration rate, and low percentage of authors with at least 1 paper/year, among others. Attending to journal of publication, cross-disciplinarity research of Spanish pharmacologists is analysed, being Neurosciences, Biochemistry & Molecular Biology and Physiology, the main border fields involved.

Abstract  

The present study is a bibliometric analysis, of publications of Spanish pharmacologists, referenced in the journals of the Pharmacology & Pharmacy subfield of the Science Citation Index- CD Edition from 1984 to 1989. During this time the scientific output of Spanish pharmacologists has been growing at an impressive rate being almost doubled. This rate being notably greater than that corresponding to publications of Spain in all science fields. This increase in scientific output was accompanied by a time-dependent decrease on year by year step basis in the expected impact factor (EIF) of publications (Articles plus Notes), from 1.71 in 1984 to 1.28 in 1989, in close correlation with an increase of mean number of authors per paper, from 3.67 to 4.16 authors/paper, respectively. Moreover, the larger the number of authors/paper, the smaller the EIF. Only 8 journals cumulated more than 50% of the papers. The scientific production was geographically localized at a high extent (Barcelona, Madrid, Valencia accounted for the 63.7% of all the papers) in governmental institutions (University, 75.2%, Hospitals, 14.1%; CSIC, 10.5%) with one large geographical area lacking any productivity.
