- Abstract
- We here perform an analysis of all 1128 publications produced by scientists during their employment at the University of Texas Institute for Geophysics, a geophysical research laboratory founded in 1972 that currently employs 23 Ph.D.-level scientists. We thus assess research performance using as bibliometric indicators such statistics as publications per year, citations per paper, and cited half-lives. To characterize the research style of individual scientists and to obtain insight into the origin of certain publication-counting discrepancies, we classified the 1128 publications into four categories that differed significantly with respect to statistics such as lifetime citation rates, fraction of papers never-cited after 10 years, and cited half-life. The categories were: mainstream (prestige journal) publications -32.6 lifetime cit/pap, 2.4% never cited, and 6.9 year half-life; archival (other refereed)-12.0 lifetime cit/pap. 21.5% never cited, and 9.5 years half-life; articles published as proceedings of conferences-5.4 lifetime cit/pap, 26.6% never cited, and 5.4 years half-life; and "other" publications (news articles, book reviews, etc.)-4.2 lifetime cit/pap, 57.1% never cited, and 1.9 years half-life. Because determining cited half-lives is highly similar to a well-studied phenomenon in earthquake seismology, which was familiar to us, we thoroughly evaluate five different methods for determining the cited half-life and discuss the robustness and limitations of the various methods. Unfortunately, even when data are numerous the various methods often obtain very different values for the half-life. Our preferred method determines halflife from the ratio of citations appearing in back-to-back 5-year periods. We also evaluate the reliability of the citation count data used for these kinds of analysis and conclude that citation count data are often imprecise. All observations suggest that reported differences in cited half-lives must be quite large to be significant

- Abstract
- Ein britischer Forscher hat sich die Mühe gemacht, die geografischen Muster der Zitierungen von 1981 bis zur Gegenwart freizulegen. Das Ergebnis: Die publizistische Wahrnehmung ist in der Wissenschaft äußerst ungleich verteilt. Die USA dominieren mit großem Abstand vor dem Rest der WeIt. Und auch dort konzentrieren sich die Verweise auf einige wenige Ballungsräume der Forschung. Michael Batty vom Centre for Advanced Spatial Analysis in London bediente sich für seine Analyse der Datenbank "ISIHighlyCited.com" (http: //www.isihighlycited.com/), in der Forscher aus verschiedenen Disziplinen aufgelistet werden, die die weltweit meisten Zitate auf sich gezogen haben. In diesen Ranglisten nehmen die akademischen Edelschmieden aus den USA etwa jene Rolle ein, die Österreichische Athleten im Alpinschisport besetzen. Einzig der Forschungsraum London kann mit der Konkurrenz aus Übersee halbwegs mithalten. Der Artikel "Citation Geography: It's About Location" von Michael Batty erschien im Magazin "The Scientist" (Band 17, Heft 16/10, Ausgabe vom 25.8.03; http://www.thescientist.com/yr2003/aug/opinion 030825.html). Die Zeitschrift ist nach individueller Registrierung frei zugänglich. Der Homepage des Autors http: //www.casa.ucl.ac.uk/citations/ können weitere Details entnommen werden. Ob die Anzahl derZitate auch etwas über die wissenschaftliche Qualität aussagt, ist genau so Gegenstand von Diskussionen, wie dies etwa bei den "Impact-Faktoren" von Journalen der Fall ist (vgl. "Kann wissenschaftliche Qualität gemessen werden?", http://science.orf.at/science/news/58648). Ganz wertfrei kann man die ISI-Daten jedenfalls dazu verwenden, um herauszufinden, in welchem Land, in welcher Stadt und in welcher Institution die meist zitierten Forscher dieses Erdballs sitzen. Das Ergebnis dieser von Michael Batty erstellten "Geografie derwissenschaftlichen Zitierung" ist eindeutig: Einige Wenige ziehen den Großteil der publizistischen Aufmerksamkeit auf sich - und lassen für den Rest nur wenig über. Diese Aussage gilt gleichermaßen für Ranglisten von Städten, Institutionen und Ländern. Und: In allen drei Fällen kommen die Spitzereiter aus dem US-amerikanischen Raum.
