Abstract

Über das Ausmaß der Nutzung der Zitationsindizes des Institute for Scientific Information ist wenig bekannt; dies gilt insbesondere auch für den Social Science Citation Index (SSCI). Eine im Sommer 1999 durchgeführte Untersuchung unter deutschen Soziologen bestätigte bekannte Schwachpunkte des SSCI in Bezug auf Sprachraum und Literaturformen. Rund die Hälfte der antwortenden Soziologen gehörte zu den Nutzern, von denen wiederum die Hälfte den SSCI nur selten in Anspruch nahmen. etwa die Hälfte der Antwortenden hält die Auswertung von Zitationsindizes für eine sinnvolle informationelle Ergänzung der Evaluation sozialwissenschaftlicher Forschungsleistungen. Als weiteres Umfragergebnis zeigte sich, dass das Phanomen unsubstanzieller Koautorenschaft auch in der Soziologie weit verbreitet ist

Abstract

In the study of growth dynamics of artificial and natural systems, the scaling properties of fluctuations can exhibit information an the underlying processes responsible for the observed macroscopic behavior according to H.E. Stanley and colleagues (Lee, Amaral, Canning, Meyer, & Stanley, 1998; Plerou, Amaral, Gopikrishnan, Meyer, & Stanley, 1999; Stanley et al., 1996). With such an approach, they examined the growth dynamics of firms, of national economies, and of university research fundings and paper output. We investigated the scaling properties of journal output and impact according to the Journal Citation Reports (JCR; ISI, Philadelphia, PA) and find distributions of paper output and of citations near to lognormality. Growth rate distributions are near to Laplace "tents," however with a better fit to Subbotin distributions. The width of fluctuations decays with size according to a power law. The form of growth rate distributions seems not to depend an journal size, and conditional probability densities of the growth rates can thus be scaled onto one graph. To some extent even quantitatively, all our results are in agreement with the observations of Stanley and others. Further on, a Matthew effect of journal citations is confirmed. If journals "behave" like business firms, a better understanding of Bradford's Law as a result of competition among publishing houses, journals, and topics suggests itself.
