Abstract
Bibliometric studies at the micro level are increasingly requested by science
managers and policy makers to support research decisions. Different measures
and indices have been developed at this level of analysis. One type of indices,
such as the h-index and g-index, describe the most productive core of the output
of a researcher and inform about the number of papers in the core. Other indices,
such as the a-index and m-index, depict the impact of the papers in the core.
In this paper, we present a new index which relates two different dimensions
in a researchers productive core: a quantitative one (number of papers) and
a qualitative one (impact of papers). In such a way, we could obtain a more
balanced and global view of the scientific production of researchers. This new
index, called q2-index, is based on the geometric mean of h-index and the median
number of citations received by papers in the h-core, i.e., the m-index, which
allows us to combine the advantages of both kind of indices.
