The study seeks to identify the influence of local and regional publications in the production of public health research papers
in the Latin American region. A citation analysis of the papers published in the following three leading journals in the field
of public health was conducted: Revista Médica de Chile (Chile) (RMCh); Archivos Latinoamericanos de Nutrición (Venezuela) (ALAN); and Salud Pública de México (México) (SPM). Papers were analyzed for the period 2003–2007. SciELO (Scientific Electronic Library Online) and the printed
version of the journals were used in the analysis. Overall, 1,273 papers from 122 journal issues were analyzed. References
accounted for a total of 38,459. Over 90% of the production was published through the collaboration of two or more authors.
Author affiliation corresponded in most cases to the country of origin of the journal. References to Portuguese papers accounted
for nearly 5% in ALAN and less than 1% each in SPM and RMCh. Citations among the three journals were not significant. Only
ALAN cited RMCh and SPM over 3% each, of total citations. SPM and RMCh cited each other less than 1% of total citations. With
the exception of ALAN, most public health papers published in RMCh and SPM derived from the national collaboration of researchers
in the field. A small amount of public health knowledge communication was being transferred from Brazil to the region through
RMCh and SPM. A vertical and individual (per journal/country) model of knowledge communication in public health was identified.
counting the publications, an attempt was also made to gauge the scientific influence using the standard techniques of citationanalysis. Since a reliable estimate of citation impact requires a certain time (at least a few years) after publication, papers

impact of scholarly contributions between IS and other COB disciplines. We apply and extend field co-citationanalysis (Sugimoto et al. 2008 ) using COB fields. Discipline-defining journal sets were used as proxies of the COB disciplines. We describe the
In this paper I discuss the relation between widely used “Scientometric” measures and “reputation” of research groups within
the scientific community. To this goal, I present the result of the detailed comparison of two research groups of theoretical
astrophysics in post-world-war-2nd Japan. Though one of the two groups gained much higher reputation within the research community,
we could not find much difference in the macroscopic indices such as the number of publications or the average citation index.
The two groups showed similar scores for these macroscopic indices. This result suggests that widely used quantitative measures
of the productivity do not give meaningful measure for the actual contribution of a research group to science.

The objective of this study is to use a clustering algorithm based on journal cross-citation to validate and to improve the
journal-based subject classification schemes. The cognitive structure based on the clustering is visualized by the journal
cross-citation network and three kinds of representative journals in each cluster among the communication network have been
detected and analyzed. As an existing reference system the 15-field subject classification by Glänzel and Schubert (Scientometrics
56:55–73, <cite>2003</cite>) has been compared with the clustering structure.

The quality and credibility of Internet resources has been a concern in scholarly communication. This paper reports a quantitative
analysis of the use of Internet resources in journal articles and addresses the concerns for the use of Internet resources
scholarly journals articles. We collected the references listed in 35,698 articles from 14 journals published during 1996
to 2005, which resulted in 1,000,724 citations. The citation data was divided into two groups: traditional citations and Web
citations, and examined based on frequencies of occurrences by domain and type of Web citation sources. The findings included:
(1) The number of Web citations in the journals investigated had been increasing steadily, though the quantity was too small
to draw an inclusive conclusion on the data about their impact on scientific research; (2) A great disparity existed among
different disciplines in terms of using information on the Web. Applied disciplines and interdisciplinary sciences tended
to cite more information on the Web, while classical and experimental disciplines cited little of Web information; (3) The
frequency of citations was related to the reputation of the author or the institution issuing the information, and not to
the domain or webpage types; and (4) The researchers seemed to lack confidence in Internet resources, and Web information
was not as frequently cited as reported in some publications before. The paper also discusses the need for developing a guideline
system to evaluate Web resources regarding their authority and quality that lies in the core of credibility of Web information.

As the population ages in Taiwan, stroke research has received greater attention in recent years. Strokes have significant
impacts on the health and well-being of the elderly. To formulate future research policy, information on stroke publications
should be collected. In this research, we studied stroke-related research articles published by Taiwan researchers which were
indexed in the Science Citation Index from 1991 to 2005. We found that the quantity of publications has increased at a quicker
pace than the worldwide trend. Over the years, there has been an increase in international collaboration, mainly with researchers
in the U.S. Article visibility, measured as the frequency of being cited, also increased during the period. It appears that
stroke research in Taiwan has become more globally connected and has also improved in quality. The publication output was
concentrated in a few institutes, but there was a wide variation among these institutes in the ability to independently conduct
research. A wide array of keywords indicated a probable lack of continuity in research. Nevertheless, there was an inverse
relationship between stroke mortality and number of published articles in Taiwan. To improve the quality and efficiency of
stroke research, continuity in research focuses needs to be maintained, and thus funding should be allocated on a long-term
basis to institutes with a proven record of success.
This paper discusses the publications of Third World Countries (TWC) in theScience Citation Index by disciplines. TWC documents which were nationally cross-linked at least 20 times were identified and their citing documents
categorised into seven disciplines. The top 12 TWC are discussed vis--vis their population, Gross National Product, and the
extent of participation usingobserved rates of contribution in each discipline andexpected rates based on numbers of citations received. Brazil, Mexico, Argentina and Chile, appeared most frequently in the top five ranks
in each of the seven disciplines; however, none of these countries had neither the largest population nor the highest GNP
per capita. Overall observed rates exceeded expected rates in all but two disciplines: Biomedicine and Agriculture. Physics
& Engineering had the highest overall observed rate with the top five TWC exceeding the overall and their individual expected
rates. Brazil and Venezuela led by exceeding their expected rates in four of the seven disciplines.
