Zubarev nonequilibrium statistical operator method in Renyi statistics. Reaction-diffusion processes

The Zubarev nonequilibrium statistical operator (NSO) method in Renyi statistics is discussed. The solution of $q$-parametrized Liouville equation within the NSO method is obtained. A statistical approach for a consistent description of reaction-diffusion processes in "gas-adsorbate-metal" system is proposed using the NSO method in Renyi statistics.Comment: 9 pages, no figure

Construction of time preference: an investigation of the role of elicitation method in experimental elicitation of time preference.

The idea of preference reversal and construction of preference is not new to literature in decision making. Indeed, several theories have been developed to explain it. (Lichtenstein and Slovic, 2006). The present paper considers heuristics activated in different elicitation procedures applied in time preference research. I show that activation of these rules in correspondence with different elicitation methods leads to observation of a particular pattern most frequently reported in time preference literature: hyperbolic discounting. In particular, I analyze two most diffused elicitation procedures, matching task and two variations of choice task in multiple price list format (MPL). In a series of experiments I demonstrate that matching task is characterized by choice of focal amounts and anchoring to previously reported amount. At the same time, choice in MPL format largely depends on the structure of the list from which the choice is made. I study two widely used structures of MPL choice task format: (a) MPL with nominal structure (Green et al, 1997), where choice alternatives correspond to the same nominal amounts that are available at different time horizons; (b) MPL with interest rate structure (Coller and Williams, 1999), in which monetary alternatives at each time horizon in consideration are constructed as increases corresponding to a fixed interest rate. Although these two elicitation structures activate similar decision processes they lead to observation of qualitatively different results that are in large part defined by the underlying structure of the list of alternatives. I show that matching task and MPL with nominal structure lead to observation of hyperbolic evidence, that could be of different kinds depending on the structure of MPL table. At the same time, elicitation with MPL with interest rate structure leads to observation of rather stable time preference that can be well approximated by exponential discounting.

Consistent description of kinetics and hydrodynamics of dusty plasma

A consistent statistical description of kinetics and hydrodynamics of dusty plasma is proposed based on the Zubarev nonequilibrium statistical operator method. For the case of partial dynamics the nonequilibrium statistical operator and the generalized transport equations for a consistent description of kinetics of dust particles and hydrodynamics of electrons, ions and neutral atoms are obtained. In the approximation of weakly nonequilibrium process a spectrum of collective excitations of dusty plasma is investigated in the hydrodynamic limit.Comment: 31 pages, no figure

Framing in choice task

The direction of speed-up - delay effect is reversed in elicitation with choice task in MPL format. The model of intertemporal choice with reference point cannot explain this reversal. I claim that this reversal is due to the structure of elicitation taskintertemporal choice, MPL, choice task, framing.

Perceived authenticity and museum visitors' behavior: a case of South Tirol's museum of archeology in Bolzano

In this study we analyze perception of authenticity by visitors of South Tyrol's museum of archeology, best known as Otzi museum, in the Autonomous Province of Bolzano (Italy). With the help of factor analysis we individuate two factors related to authenticity and study the determinants of the perception of authenticity by the visitors. Individuated factors are then employed to explain visitors' behavior at the museum. In particular, we study how perception of authenticity is related to the time visitors spend at the museum. Next we investigate the influence of authenticity on shopping behavior of museum visitors. The relevant data were obtained from a survey undertaken in the months from June to August 2010 at site. The empirical findings provide important insights for the management of the Otzi museum.Authenticity, museum management, souvenirs, factor analysis, tobit regression.
