“…16 The H-index consists of a single number that seeks to summarize two dimensions of academic performance: productivity (number of publications) and visibility (citations for those publications). 18,30,31 One point that has been emphasized about the H-index is that it counteracts both the excessive amount of publications with few citations as well as low productivity with many citations. 32 In our analysis, the median H-index for researchers in the field of Hematology/Oncology was 11, which was significantly higher for categories 1A and IB, with an H-index of 14.…”

Conflict of interest: noneObjective: several studies have examined the academic production of the researchers at the CNPq, in several areas of knowledge. The aim of this study was to evaluate the scientific production of researchers in Hematology/Oncology who hold scientific productivity grants from the Brazilian Council for Scientific and Technological Development. Methods: the Academic CVs of 28 researchers in Hematology/Oncology with active grants in the three-year period from 2006 to 2008 were included in the analysis. The variables of interest were: institution, researchers' time after doctorate, tutoring of undergraduate students, masters and PhD degree, scientific production and its impact. Results: from a total of 411 researchers in Medicine, 28 (7%) were identified as being in the area of Hematology/Oncology. There was a slight predominance of males (53.6%) and grant holders in category 1. Three Brazilian states are responsible for approximately 90% of the researchers: São Paulo (21,75%), Rio de Janeiro (3,11%), and Minas Gerais (2, 7%). During their academic careers, the researchers published 2,655 articles, with a median of 87 articles per researcher (IQR = 52 to 122). 65 and 78% of this total were indexed on the Web of Science and Scopus databases, respectively. The researchers received 14,247 citations on the WoS database with a median of 385 citations per researcher. The average number of citations per article was 8.2. Conclusion: in this investigation, it was noted that researchers in the field of Hematology/Oncology have a relevant scientific output from the point of view of quantity and quality compared to other medical specialties.

“…The log-linear trend in citation accrual (Figure 3) appears generic (Burrell, 2007), applies to many journals, and is neatly summarised by the h-index, since it reflects the gradient of this relationship. Fewer than h papers (where h is the h-index) depart from this trend (i.e., those at the top left of Fig.…”

An expert ranking of forestry journals was compared with journal impact factors and h-indices computed from the ISI Web of Science and internet-based data. Citations reported by Google Scholar offer an efficient way to rank all journals objectively, in a manner consistent with other indicators. This h-index exhibited a high correlation with the journal impact factor (r=0.92), but is not confined to journals selected by any particular commercial provider. A ranking of 180 forestry journals is presented, on the basis of this index.

Measuring the research contribution of management academics using the Hirsch-index

There is an increasing emphasis on the use of metrics for assessing the research contribution of academics, departments, journals or conferences. Contribution has two dimensions: quantity which can be measured by number/size of the outputs, and quality which is most easily measured by the number of citations. Recently, Hirsch proposed a new metric which is simple, combines both quality and quantity in one number, and is robust to measurement problems. This paper applies the h-index to three groups of management academics -BAM Fellows, INFORMS Fellows, and members of COPIOR -in order to evaluate the extent to which the h-index would serve as a reliable measure of the contribution of researchers in the management field.
