“…In the first one, one of the most influential proposals is the h-index by Hirsch (Hirsch 2005), which has been subject of multiple extensions and corrections (Alonso et al 2009). Other individual researcher indices have also been proposed extending the h-index, such as the g-index (Egghe 2006), q 2 -index (Cabrerizo et al 2010), and others (Bornmann et al 2010;Kosmulski 2009). …”
The problem of comparing academic institutions in terms of their research production is nowadays a priority issue. This paper proposes a relative bidimensional index that takes into account both the net production and the quality of it, as an attempt to provide a comprehensive and objective way to compare the research output of different institutions in a specific field, using journal contributions and citations. The proposed index is then applied, as a case study, to rank the top Spanish universities in the fields of Chemistry and Computer Science in the period ranging from 2000 until 2009. A comparison with the top 50 universities in the ARWU rankings is also made, showing the proposed ranking is better suited to distinguish among non-elite universities.

“…The hpd-index (Kosmulski 2009) is very similar to the h-index, except that it adjusts for 983 the age of a publication. Rather than adjust per year, the metric is adjusted per decade.…”

The purpose of this study is to educate biologist and other 9 scientists about some of the wide literature about impact factors, including highlighting their 10 strengths and weaknesses. This includes a thorough exploration of dozens of such indices by 11 comparing how they perform through repeated calculation of data representing 15 years of 12 scientific output of a single individual from beginning through mid-career.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
