Dear Sir,

Impact factor it is a problem concerning not only Sigmetrics people , but
all research community. The core of this problem is the lack of a
theoretical framwork where any measurement makes sense.I would like to know
your opinion about the papers:"The Rasch Model. Measuring the Impact Factor
of Sientific Journals: Analytical Chemistry", (Journal of the American
Society for Information Science, JASIS, 47(6):458-467, 1996).

A way for defining a measurement is through latent variables, as it is
shown in the papers:"The Rasch Model. Measuring Information from Keywords:
The Diabetes Field", (JASIS 47(6):468-476, 1996); "The diffusion of
Scientific Journals Analyzed through Citations", (JASIS, 48(10)953-958);
"Equating Research Production in Different Scientific Fields" (Information
Processing & Management Vol. 34, No 4, pp. 465-470, 1998).

Thank you very much.

P. Alvarez

Professor
