AVALIAÇÃO DOS CIENTISTAS: UTILIZAMOS AS MÉTRICAS CORRETAS?
SCIENTISTS’ ASSESSMENT: ARE WE USING THE CORRECT METRICS? The use of metrics to evaluate scientists is widespread in the present time, with implications for hiring, fellowships, and research grants. Such fact requires that metrics must be constantly scrutinized to be improved. This work analyzes the use of metrics in the area of chemistry in Brazil and discusses its limitations and shortcomings. The main findings indicate that the use of the impact factor must be complemented by the cited half-life of the journals, and a composite metric named influence factor is proposed, similar to the R-impact. The h-index is not a good metric anymore because does not correct for authorship inflation. The individual h-index (hi), which takes into account fractional counting of citations, is more reliable than the h-index. An analysis on the use of hi-index with randomly selected 15 Brazilian chemists among the top 500 more productive shows an important effect on the ranking order.
期刊介绍:
Química Nova publishes in portuguese, spanish and english, original research articles, revisions, technical notes and articles about education in chemistry. All the manuscripts submitted to QN are evaluated by, at least, two reviewers (from Brazil and abroad) of recognized expertise in the field of chemistry involved in the manuscript. The Editorial Council can be eventually asked to review manuscripts. Editors are responsible for the final edition of QN.
