Can networks of journal-journal citations be used as indicators of change in the social sciences?
نویسنده
چکیده
Aggregated journal-journal citations for 1999 are compared with similar data in the Journal Citation Reports 1998 of the Social Science Citation Index. In addition to indicating local change, probabilistic entropy measures enable us to analyze changes in distributions at different levels of aggregation. The indicators are compared by elaborating the journal-journal mappings and in relation to similar developments in the Science Citation Index. Specialty formation seems a more important mechanism in the development of the social sciences than in the natural and life sciences, but the developments are volatile. The use of aggregate statistics based on the Science Citation Index is ill-advised in the case of the social sciences because of differences in the underlying dynamics.
