    Example text

    Although a specific research would be conducted at a specific university that does not mean that the author is still at that university a year or two after the publication. Or when evaluating the work of a single researcher it is possible that his or her most important work has just been published and therefore it has not yet received any recognition in the form of citations. Rewarding research as measured through citations always rewards past success and it does not have to have anything to do with the current research conducted or the future potential.

    And it will probably take at least another year before any potential citations to it would appear in the citation databases. Because scholarly communication takes a long time citations need to be accumulated for some time before citation analyses can be done. Brody, Harnad, & Carr (2006) referred to the Institute for Scientific Information (ISI) Journal Citation Reports from 2003 and wrote that, for instance, in physics it can take up to 5 years before a paper has received half of the citations that it is going to ever receive (a measurement referred to as cited half-life) and that the typical cited half-life for journals in physics is between 3 and 10 years.

    Citations do imply use of the cited work, but the citations alone do not reveal anything about how the cited work has been used, as negative or criticizing citations can exist too. Negative citations, arguing against the ideas or findings in earlier publications, are relatively rare it would seem, as earlier studies have found various small amounts of negative citations: 14% (Moravcsik & Murugesan, 1975), 5% (Chubin & Moitra, 1975), and 2% (Brooks, 1985; Cano, 1989), of their respective samples.
