Abstract  

The assumption underlying citation analysis is that the citing authors select their references in a rational manner. The present study, based on a very homogeneous collection of clinical trials from a meta-analysis, provides a partial verification of this idea: citing authors prefer large studies to smaller ones, they also seem to prefer studies representing the minority view of the research issue, perhaps in order to make their presentation more balanced. On the other hand, in this instance the inclusion of a placebo in the study design does not affect citation frequency. Furthermore, the conjecture that heuristic value is a main determinant of citability is not settled.

Abstract  

This research was conducted on a sample of 840 respondents who represent half of the Croatian population of young scientists. There are three main features which define the publication productivity of young scientists. 1) Despite the worsened position of R & D, they publish more scientific papers than the young generations of scientists at the beginning of the nineties. 2) Differences between a highly-productive minority, which produces on average half of all scientific publications, and a low-productive majority is already apparent in young scientists. 3) The productivity of young scientists is formed according to productivity patterns typical of particular scientific fields and disciplines.With regard to the explanation of productivity, the following has been found. a) An expansion of the set of predictors resulted in an improvement in the explanation of the productivity of young scientists compared with previous surveys. b) Among the factors which contribute significantly to the explanation of the quantity of scientific publications, the most powerful predictor is attendance at conferences abroad, followed by scientific qualifications and some gatekeeping variables. c) Besides certain similarities, scientific fields also show a specific structure of determinants of young scientists' productivity.

Abstract  

Context. The use of citation frequency and impact factor as measures of research quality and journal prestige is being criticized. Citation frequency is augmented by self-citation and for most journals the majority of citations originate from a minority of papers. We hypothesized that citation frequency is also associated with the geographical origin of the research publication. Objective. We determined whether citations originate more frequently from institutes that are located in the same country as the authors of the cited publication than would be expected by chance. Design. We screened citations referring to 1200 cardiovascular publications in the 7 years following their publication. For the 1200 citation recipient publications we documented the country where the research originated (9 countries/regions) and the total number of received citations. For a selection of 8864 citation donor papers we registered the country/region where the citing paper originated. Results. Self-citation was common in cardiovascular journals (n = 1534, 17.8%). After exclusion of self-citation, however, the number of citations that originated from the same country as the author of the citation recipient was found to be on average 31.6% higher than would be expected by chance (p<0.01 for all countries/regions). In absolute numbers, nation oriented citation bias was most pronounced in the USA, the country with the largest research output (p<0.001). Conclusion. Citation frequency was significantly augmented by nation oriented citation bias. This nation oriented citation behaviour seems to mainly influence the cumulative citation number for papers originating from the countries with a larger research output.
