title: Interpretation of the nonextensivity parameter q in some applications of tsallis statistics and Levy distributions
abstract: The nonextensivity parameter q occurring in some of the applications of Tsallis statistics (known also as index of the corresponding Levy distribution) is shown to be given, in the q>1 case, entirely by the fluctuations of the parameters of the usual exponential distribution.
