Hirsch-index for countries based on Essential Science Indicators data

TLDR
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, attempting to fit a recent theoretical model relating the h- index with two traditional scientometric indicators: the number of publications and the mean citation rate.
Abstract
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.

The state of h index research. Is the h index the ideal way to measure research performance

TL;DR: 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.

A multilevel meta-analysis of studies reporting correlations between the h index and 37 different h index variants

TL;DR: The results of a three-level cross-classified mixed-effects meta-analysis show a high correlation between the h index and its variants: Depending on the model, the mean correlation coefficient varies between .8 and .9, which means that there is redundancy between most of the hIndex variants and the h Index.

TL;DR: 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.

An index to quantify an individual's scientific output

J. E. Hirsch
TL;DR: In this article, the authors propose the index $h, defined as the number of papers with citation number higher or equal to $h, as a useful index to characterize the scientific output of a researcher.
