h-Index: A review focused in its variants, computation and standardization for different scientific fields

How does one measure the quality of science? The question is not rhetorical; it is extremely relevant to promotion committees, funding agencies, national academies and politicians, all of whom need a means by which to recognize and reward good research and good researchers. Identifying high‐quality science is necessary for science to progress, but measuring quality becomes even more important in a time when individual scientists and entire research fields increasingly compete for limited amounts of money. The most obvious measure available is the bibliographic record of a scientist or research institute—that is, the number and impact of their publications.

Currently, the tool most widely used to determine the quality of scientific publications is the journal impact factor (IF), which is calculated by the scientific division of Thomson Reuters (New York, NY, USA) and is published annually in the Journal Citation Reports (JCR). The IF itself was developed in the 1960s by Eugene Garfield and Irving H. Sher, who were concerned that simply counting the number of articles a journal published in any given year would miss out small but influential journals in their Science Citation Index (Garfield, 2006). The IF is the average number of times articles from the journal published in the past two years have been cited in the JCR year and is calculated by dividing the number of citations in the JCR year—for example, 2007—by the total number of articles published in the two previous years—2005 and 2006.

Owing to the availability and utility of the IF, promotion committees, funding agencies and scientists have taken to using it as a shorthand assessment of the quality of scientists or institutions, rather than only journals. As Garfield has noted, this use of the IF is often necessary, owing to time …

The Hirsch index and related impact measures

The Essential Science Indicators (ESI) database is widely used to evaluate institutions and researchers. The objective of this study was to analyze trends and characteristics of papers in the subject category of water resources in the ESI database of the Institute for Scientific Information (ISI). Distributions of document type, language of publication, scientific output, and publication of journals are reported in this article. Five indicators (the number and ranking of total papers, first-author papers, corresponding-author papers, independent papers, and collaborative papers) were applied to evaluate country, institute, and author performances. In addition, the numbers of authors cited, numbers of institutes cited, numbers of countries cited, and numbers of subject areas cited were also used to evaluate ESI papers. Results showed that 265 papers, all written in English, were listed in 27 journals in the field of water resources. A review paper was more likely to be included in the ESI than a research paper. Journal of Hydrology published the most papers. The USA and UK were the two leading nations. ESI papers published in the US were more likely to involve inter-institutional collaboration than papers published in the UK. The University of Arizona was the most productive institute. Some papers that were almost excluded from the ESI database appear to have consistently received annual high frequencies of citation. Perhaps the 10 year criterion for inclusion in the ESI should be reassessed.

High-impact papers presented in the subject category of water resources in the essential science indicators database of the institute for scientific information

The authors present ranked lists of world’s countries — with main focus on EU countries (together with newly acceeded and candidate countries) — by their h-index on various science fields. As main source of data Thomson Scientific’s Essential Science Indicators (ESI) database was used. EU countries have strong positions in each field but none of them can successfully compete with the USA. The modest position of the newly accessed and candidate countries illustrate the importance of supportive economic and political background in order to achieve scientific success. An attempt is made to fit a recent theoretical model relating the h-index with two traditional scientometric indicators: the number of publications and the mean citation rate.

INTRODUCTION Rapid developments take place in communication technology. It is a hard task to keep pace with them, but unavoidable. The scene of electronic communication and publication, the Internet has originally been constructed for scientific communication and publication of scientists. Nowadays, the electronic communication has spread all over the world. Though the share of sciences has been diminished, the progress in the scientific electronic communication has not been broken. AIM The authors delineate the present situation in electronic communication in general and in Hungary. METHODS The authors asked by questionnaire survey the medical scientists and professionals about their knowledge and usage of modern publication possibilities. For comparison's sake, the authors referred to some foreign surveys as well. RESULTS In Hungary, the communication possibilities on the Internet--and the electronically accessible publications--are at the readers' disposal at the universities and academic institutions. The opinions about the popularity and effects of electronic publication are generally positive. Concerns were expressed in connection with the possible weaker professional control in case of certain types of publication. In the opinion of the majority of questioned people the electronic form of publication will never replace the traditional one completely, it will be, however, dominant.
