Impact factor and/or Hirsch index?
Orvosi Hetilap, 2007Lehet-e valóban a tudományos teljesítményt csak a kutatók publikációinak számával mérni? Az Institute for Scientific Information által megjelentetett impaktfaktor-listák évtizedek óta szolgálnak mérőeszközként a tudományos tevékenység minősítésére.

Further characterizations of the Hirsch index
Scientometrics, 2010The Hirsch index is a number that synthesizes a researcher's output. It is defined as the maximum number h such that the researcher has h papers with at least h citations each. Four characterizations of the Hirsch index are suggested. The most compact one relies on the interpretation of the index as providing the number of valuable papers in an output ...

An alternative axiomatization of the Hirsch index
Journal of Informetrics, 2014Abstract We axiomatize the well-known Hirsch index (h-index), which evaluates researcher productivity and impact on a field, and formalize a new axiom called head-independence. Under head-independence, a decrease, to some extent, in the number of citations of “frequently cited papers” has no effect on the index.

An axiomatic characterization of the Hirsch-index
Mathematical Social Sciences, 2008The Hirsch-index is a well-known index for measuring and comparing the output of scientific researchers. The main contribution of this article is an axiomatic characterization of the Hirsch-index in terms of three natural axioms. Furthermore, two other scientific impact indices (called the w-index and the maximum-index) are defined and characterized in

Axiomatics for the Hirsch research output index [PDF]
, 2009 The Hirsch index is a number that synthesizes a researcher’s output. It is defined as the maximum number h such that the researcher has h papers with at least h citations each. Two axiomatic characterizations of this index are suggested. One of them provides a simple conceptualization of the Hirsch index: after selecting those outputs deserving index 1,
