    Abstract
    Describes a method for analysing 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, channelled through citations that an 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

    Abstract
    Focuses on a way to determine a ranking of science journals according to the number of citations-to and items-published data used by Science Citation Insitute of Citation Reports of the Institute for Science Information to determine journal ranking by impact factor. Applies latent traits theory to bibliometrics
