Abstract
A method is described for analyzing the diffusion of scientific journals, using the Rasch model as the measuring instrument. It is applied to the 10-year distribution of citations to journals of the Subject Category “Physics” by year of publication of cited articles with data obtained from the SCI Journal Citation Reports of ISI for the year 1994. Diffusion in a scientific field would be regarded as the dissemination of knowledge, channeled through citations that are distributed over different periods of time and propagated by means of scientific journals: here it is considered to be a latent variable defined by a particular set of items (the citations made in different time periods), and the Rasch model is used as an instrument for measuring that variable. © 1997 John Wiley & Sons, Inc.
