The Role of Personal Preferences in Economics

Prof. Dr Thomas Dohmen from the Institute for Applied Microeconomics, University of Bonn, Germany is to deliver an honorary lecture at the upcoming April Academic Conference at HSE University April 9 – 12. HSE News Service spoke with Dr. Dohmen about his work on the Global Preferences Survey (GPS), an international survey of epic proportions that he helped develop and analyze in order to learn whether individuals differ in terms of economic preferences by country, and more.

Patients Go Online: Virtual Self-diagnosis and Its Implications

Mobile and web-based applications available today allow patients to self-diagnose and self-prescribe treatment. Galina Polynskaya and Margarita Mesropyan have examined  to what extent patients and doctors trust such technology.

How Equality Started in Research

Legally, the 1917 revolution solved the gender issue in the Russian academic community. The doors to the profession opened for women, but a ‘glass ceiling’ remained. Ekaterina Streltsova and Evgenia Dolgova studied who it affected and why. This study is the first to present a socio-demographic analysis of the female academic community in Moscow and Leningrad during the early Soviet era.

The difference between manipulability indexes in IC and IANC models
Veselova Y. A. Economics. EC. Высшая школа экономики, 2012. No. 17/EC/2012.

We consider the problem of manipulability of social choice rules in the impartial anonymous and neutral culture model (IANC) and provide a new theoretical study of the IANC model, which allows us to analytically derive the difference between the Nitzan-Kelly index in the Impartial Culture (IC) and IANC models. We show in which cases this difference is almost zero, and in which the Nitzan-Kelly index for IANC is the same as for IC. However, in some cases this difference is large enough to cause changes in the relative manipulability of social choice rules. We provide an example of such cases.

Roll Pass Design Development with SPLEN(Rolling) Computer Software
Aksenov S. A., Chumachenko E. N., Logashina I. V. et al. Hutnické listy. 2010. No. 4. P. 110-113.
The technological process considered in the paper is a rolling of a round bar in roughing mill group, which consist of four passes. The computer simulation of the process shows that the local plastic deformations occurring in the material are extremely large, which may lead to the appearing of defects. The investigations performed, led to the development of new roll pass design, which almost halved the maximum value of local plastic deformation in the material during rolling. Since full 3D finite element method (FEM) based models needs significant amount of computer memory and CPU time, it was not suitable for the performed study, which involves a bulk of simulations with different initial conditions. Therefore, the quick algorithms for simulation of rolling processes, which based on so-called “2.5D” method, have been used. This method, due to number of simplifications, is significant faster than conventional 3D FEM, and at the same time it allows to reach good accuracy of the model. The developed computer software SPLEN(Rolling) which implements “2.5D” FEM simulations was applied for computations and analysis of the results. This software is able to predict the shape evolution of rolled material, as well as distributions of strain, strain rate and temperature within the volume of deformation zone. It has been shown that computer simulation based on “2.5D” FEM implemented in SPLEN(Rolling) software can be efficiently used for roll pass design development and optimization.

Quasi – 3D Approach for BGA Package Thermal Modeling
Petrosyants K., Rjabov N. In bk.: Collection of papers presented at the 18th International Workshop on THERMal INvestigation of ICs and Systems. Budapest: EDA Publishing Association, 2012. P. 158-161.

The quasi-3D BGA package thermal model is proposed. The general 3D heat transfer problem is correctly transformed to the set of 2D equations for temperature distribution in different layers of BGA package construction. It is shown that quasi-3D model provides the reasonable accuracy for standard and thermally enhanced BGAs. The software tool OVERHEAT-BGA is developed to obtain an numerical solution with considerably (6 – 10 times) reduced CPU time in comparison with universal 3D simulators.

The good agreement between designed and measured temperatures for standard and XP BGA packages is achieved.

A New Conceptual Mathematical Model of the Scientific Capital and Its Empirical Test
Shmatko N. A., Katchanov Y. L. arxiv.org. math. Cornell University, 2013. No. v.1.
The paper puts forth an axiomatic description of the complexity of an object of sociological investigation. The proposed axioms allow us to determine complexity within the framework of mathematical sociology such as the variational principle, which is formed relative to the state of the object of sociological investigation. On the basis of this principle we can conclude the equation of state, which coincides with the stationary forward Kolmogorov equation. Based on the results of an empirical study of Russian doctorate holders, a scientific capital value was determined for each respondent by calculating an empirical distribution function for each respondent’s active properties. The goal of this study is to develop a phenomenological theory of Scientific Capital in the form of a hierarchy of variational principles. On the micro level, the principle of the maximum enables us to examine the numerous meanings of Scientific Capital based on the measurement of the actual (i.e., factually realized) distribution of active properties of a scientific field’s agent among the multitude of possible distributions. On the macro level, the principle of the minimum energy functional describes the distribution of Scientific Capital among the agents of a scientific field.
