Nonextensive quantum statistics and saturation of the PMD-SQS optimality limit in hadron–hadron scattering

Ion, D.B; Ion, M.L - In: Physica A: Statistical Mechanics and its Applications 340 (2004) 1, pp. 501-512

In this paper, new results on the analysis of hadron–hadron scattering (πN,KN,K̄N, etc.) are obtained by using the nonextensive quantum entropy and principle of minimum distance in the space of quantum states (PMD-SQS). So, using [SJ(p), Sθ(q),SJθ(p),S̄Jθ(p,q)]-Tsallis-like scattering...

Modeling the BUX index by a novel stochastic differential equation

Alács, Péter; Jánosi, Imre M. - In: Physica A: Statistical Mechanics and its Applications 299 (2001) 1, pp. 273-278

We present a new modeling approach for the fluctuations of the Budapest Stock Exchange index (BUX). The starting point is a statistical analysis of high resolution (5s) data involving the first and second time-derivative of index values (index “velocities” and “accelerations”). Based on...

When Do Stories Work? Evidence and Illustration in the Social Sciences

Gelman, Andrew; Basbøll, Thomas - In: Sociological Methods & Research 43 (2014) 4, pp. 547-570

Storytelling has long been recognized as central to human cognition and communication. Here we explore a more active role of stories in social science research, not merely to illustrate concepts but also to develop new ideas and evaluate hypotheses, for example, in deciding that a research...

La mesure du développement : un domaine propice à l'innovation méthodologique

Desrosières, Alain - In: Revue Tiers-Monde n°213 (2013) 1, pp. 23-32

</titre> Statistical production in developing countries has led to methodological innovations. Structures that are less institutionalized than in the North have led to original research, involving exposures to knowledge in demography, economics, anthropology, history, sociology, and political sciences....

Statistics and dynamics

Cohen, E.G.D - In: Physica A: Statistical Mechanics and its Applications 305 (2002) 1, pp. 19-26

The classical statistics of Boltzmann and Gibbs will be discussed. As pointed out long ago by Einstein, there is a … connection of the statistics applicable to a system and its underlying dynamics. This follows, for example, from the existence of … quantum (Bose–Einstein or Fermi–Dirac) statistics, where the underlying dynamics is quite different from classical mechanics …
