“…This was demonstrated for the BAS before (Mugnaini et al 2008) and was confirmed by the present study. The main reasons for that is the different turnover of papers, which is regarded as independent of scientific performance but rather a peculiarity of one particular field.…”

“…This is apparently a general characteristic of this area and not restricted to the BAS. However, in the NAS there is now a tendency to present more quantitative studies that are being published in significant journals (Mugnaini et al 2008). The indexes are so low within the BAS members of this area that any evaluation based on the h-index cannot even say to produce a distorted view of the field; it just does not reflect scientific performance at all.…”

“…As common knowledge, there are few Brazilian periodicals that take part in the ISI database (not always related to problems regarding quality). Consequently, the remarkable difference between the h-index of the BAS and the NAS members is not surprising (Mugnaini et al 2008). Although differences are expected due to distinct working conditions (such as funding and infrastructure) that also includes the general importance of science within the respective societies, one might wonder how those numbers would look-like if the Brazilian periodicals not in ISI would be taken into consideration.…”

Bibliometric parameters have been used in order to evaluate a scientist's performance. The h-index has been gradually accepted as the most adequate parameter for this purpose. To have an idea of this index among Brazilian scientists, we performed an analysis of this parameter for the full members of the Brazilian Academy of Sciences (BAS). The h-index of 402 members listed in 10 distinct categories by the BAS was determined, cross-checked with the curriculum vitae of each of them listed at the Plataforma Lattes database (CVL) and compared with each other. Despite the large production, mostly in journals without impact factor, the h-indexes among the BAS members are comparatively low and show a large variation in all of the 10 categories, particularly in Biomedical and Physical sciences. The highest average of h-index values was found in Biomedical, Health and Chemical sciences; the lowest values were found in Human sciences where this index is meaningless. Several problems due to the trend that new and "fresh" publications need be constantly produced (the "bakery-effect") are discussed. This study points to the need of developing countries such as Brazil to invest in national scientific journals in order to make them gradually part of the mainstream journals. This would have a positive effect on bibliometric parameters of Brazilian researchers, including the h-index.

“…Raan (2006) uses it (among other indicators and peer judgement) to compare 147 different chemistry research groups. Mugnaini et al (2008) presents a comparison based on the h-index between the Brazilian Academy of Sciences and the National Academy of Sciences of the USA.…”

The h-index and some related bibliometric indices have received a lot of attention from the scientific community in the last few years due to some of their good properties (easiness of computation, balance between quantity of publications and their impact and so on). Many different indicators have been developed in order to extend and overcome the drawbacks of the original Hirsch proposal. In this contribution we present a comprehensive review on the h-index and related indicators field. From the initial h-index proposal we study their main advantages, drawbacks and the main applications that we can find in the literature. A description of many of the h-related indices that have been developed along with their main characteristics and some of the works that analyze and compare them are presented. We also review the most up to date standardization studies that allow a fair comparison by means of the h-index among scientists from different research areas and finally, some works that analyze the computation of the h-index and related indices by using different citation databases (ISI Citation Indexes, Google Scholar and Scopus) are introduced.

“…Furthermore, there is the growing trend to evaluate and compare science achievement of authors, departments, institutions and even countries. Despite the complexity and the inevitable controversy associated with this issue (e.g., Pinto and Andrade 1999, Hirsch 2005, Jin et al 2007, Ball 2007, Mugnaini et al 2008, Kellner and Ponciano 2008, scientific publications have become paramount in this matter. For all this to work properly, there must be a reliable database where the presented IF of journals can be trusted.…”
