A Characterization Theorem Based on Truncated Moments and its Application to Some Distribution Families
A new representation theorem for distributions of real-valued random variables is presented. The theorem is based on a relationship between different truncated moments of the same random variable. As
National characteristics in international scientific co-authorship relations
As expected, international co-authorship, on an average, results in publications with higher citation rates than purely domestic papers, however, the influence of international collaboration on the national citation impact varies considerably between the countries (and within one individual country between fields).
A Hirsch-type index for journals
SummaryWe suggest that a h-type index - equal to h if you have published h papers, each of which has at least h citations - would be a useful supplement to journal impact factors.
Analysing Scientific Networks Through Co-Authorship
Co-authorship is one of the most tangible and well documented forms of scientific collaboration. Almost every aspect of scientific collaboration networks can be reliably tracked by analysing
Coauthorship Patterns and Trends in the Sciences (1980-1998): A Bibliometric Study With Implications for Database Indexing and Search Strategies
It is shown that, while copublication activity has grown considerably, the extent of coauthorship and its relation with productivity and citation impact largely varies among fields.

  • 26 July 2006
L'index-h, fonde sur le nombre de citations recues, mesure l'activite de publication and l'impact en citations, c'est un indicateur utile avec d'interessantes proprietes mathematiques, mais qui ne saurait se substituer aux indicateurs bibliometriques courants plus sophistiques.
Journal impact measures in bibliometric research
It is shown that in contrast to a common misbelief statistical methods can be applied to discrete "skewed" distributions, and that the statistical reliability of these statistics can be used as a basis for application of journal impact measures in comparative analyses.
Handbook of Quantitative Science and Technology Research: The Use of Publication and Patent Statistics in Studies of S&T Systems
After a review of developments in the quantitative study of science, particularly since the early 1970s, I focus on two current main lines of ‘measuring science’ based on bibliometric analysis. With
Science in Brazil. Part 1: A macro-level comparative study
Despite similarities and strong co-publication links with the other countries in the region, Brazil has nonetheless a specific research profile, and forms the largest potential in the Latin American region.
