Dielectric response due to stochastic motion of pinned domain walls

We study the contribution of stochastic motion of a domain wall (DW) to the dielectric AC susceptibility for low frequencies. Using the concept of waiting time distributions, which is related to the energy landscape of the DW in a disordered medium, we derive the power-law behavior of the complex susceptibility observed recently in some ferroelectrics below Curie temperature.Comment: 5 pages, 2 figures, revtex

Teaching conversational language skills to foreign students: Blended learning and interactive approaches

The timeliness of the present study is a consequence of the changing status of the Russian language in the global communication landscape. The growing international significance of Russian requires the development of new language teaching methods. This article aims to demonstrate the effectiveness of employing a blended learning approach to teaching “Russian as a foreign language” with the use of authentic speaking situations, and to show the relevance of interactive education to the teaching of conversational language skills. The primary research method for this problem is a practical method of interactive learning that allows students to hold a constructive dialogue. The author proposes a new pedagogical genre, “convergent lecture,” which takes a different approach to the instruction of foreign students. The article explains how students’ experience of acting out potential social roles in the Russian as a foreign language classroom develops their ability to speak pragmatically in everyday, professional, and educational contexts. The findings of this article may be helpful for scholars who develop educational programs for foreign students, as well as instructors interested in helping their students develop more practical communication skills in a foreign environment. © 2016 Evtyugina, Simonova and Fedorenko

The influence of reflexive educational environment on students’ reflection development in the process of social adaptation

The topicality of the research is caused by the necessity to overcome contradictions between the traditional environment of educational institutions and the socialization of future graduates related to their mental world creation, to finding their identity in terms of civilization change and the rapid development of digital technologies. The aim of the study lies in defining the additional functions of the reflexive educational environment and its influence in the formation of students’ reflexive abilities and their understanding of the relationship between reflection and adaptation process in society. The leading method to investigate this problem (issue) is the reflexive method, including introspection, self-analysis, existential techniques of ‘self-exploration’, a dialogical communicative technique that allowed identifying, through content analysis of reflexive and analytical essays of students, the types of adaptive orientations (and the reflexive repertoires based on them) from which, as they integrate, a reflexive personality style is developed. It is established that the reflexive repertoires used in the process of self-identification correspond to the four adaptive attitudes of the person: homeostatic, hedonistic, rationalistic and pragmatic. Social adaptation is manifested in a conscious change in behavior and one’s own life support system, in creating a new environment of social existence, and is accompanied by a transformation of consciousness and self-awareness. In this case, reflection is the main means of these changes and the integration of reflexive repertoires and of formed reflection levels (narrative, dialogical, cognitive and axiological) are the factors influencing the outcome of social adaptation. The results of the research are aimed at solving the problem of creating a reflexive educational environment for students’ personal development and at choosing effective ways and mechanisms for their adaptation and self-realization in society. The materials of the study can prove useful both for theoretical research of reflexive thinking development in a specially created educational environment and for the teaching activities, including a foreign language.Keywords: reflexive educational environment, reflexive orientation, reflexive repertoires, social adaptation

Comparative legal analysis of mediation in Russia and the EU

The purpose of this article is to identify the specifics of mediation procedures, review them as extrajudicial method of conflict resolution. As the methodological basis of the research we use the synergistic, phenomenological and dialectical analysis techniques to examine the main aspects of the mediation as well as identify its principal features. As a result of the study, the authors concluded that in Russia it is necessary to take into account the international experience of mediation, legislation to support the mediation process and in some cases give it forceful character, to develop cooperation with the courts and notaries with the mediators.peer-reviewe

Legal standards of free utilization of intellectual property in the sphere of digital economy

The aim of the article is the development of legal standards of free utilization of intellectual property, which will become the basis for the new complex legislative regulation of relationships, that has been arisen due to the development of digital economy. Conceptual basis for the new institutional environment can be represented by the theory of free culture, practical implementation of which provides the transition from agreement-based monopolistic rhetoric towards free utilization of the results of intellectual activity in the cyber environment. We conclude the need to define the legal regime for intellectual property, dependent on its intended use into commercial and non-commercial. We propose to free the sphere of non-commercial from as many legislative barriers as possible. We also propose to widen the use of simplified registration procedures with the participation of commercial organizations, as well as intellectual property (IP) data bases. The preservation of copyright in this sphere is sensible. The principles of equity, fairness should be fundamental institutions for the free utilization of IP. Authors propose the most open and vast rules of communication within the digital environment, which have evolved naturally. Separate standards exists in the form of concepts requiring practical implementation, others have been legally enforced, such as the priority of market mechanisms over government regulation of Internet, principle of balance of right-holders and users. Absence of unified standards of synchronization of digital hardware and high cost of automated systems of control with exclusive rights within the Internet network (e.g. Swiss DRM) oppose the development of digital economy. The results of the study can be used in further development of the stated problems.peer-reviewe

Critical Behaviour of 3D Systems with Long-Range Correlated Quenched Defects

A field-theoretic description of the critical behaviour of systems with quenched defects obeying a power law correlations $\sim |{\bf x}|^{-a}$ for large separations ${\bf x}$ is given. Directly for three-dimensional systems and different values of correlation parameter $2\leq a \leq 3$ a renormalization analysis of scaling function in the two-loop approximation is carried out, and the fixed points corresponding to stability of the various types of critical behaviour are identified. The obtained results essentially differ from results evaluated by double $\epsilon, \delta$ - expansion. The critical exponents in the two-loop approximation are calculated with the use of the Pade-Borel summation technique.Comment: Submitted to J. Phys. A, Letter to Editor 9 pages, 4 figure

Nash equilibrium design in the interaction model of entities in the customs service system

The urgency of the analyzed issue is due to the importance of the use of economic-mathematical tools in the course of modeling the interaction of the entities in the customs service system that is necessary for the development of foreign economic activity (FEA) of any state. The purpose of the article is to identify effective strategies for the interaction between the participants of foreign trade activities with customs brokers. The leading method to the study of this issue is economic-mathematical modeling, allowing studying the process of making decisions while choosing the strategy of cooperation between the customs broker and his client. Results: the article suggests the mathematical model to optimize the management mechanisms of interaction between enterprises, engaged in foreign trade, and customs dealers. The data of this article may be useful in modeling interaction of the entities in the customs service system using the methods of game theory. The model of “customer - customs broker” is implemented as a bimatrix game. Assuming the noncooperativegame the authors solve the problem of finding Nash equilibrium in mixed strategies. © 2016 Fedorenko et al

Induced Scattering and Two-Photon Absorption of Alfven Waves with Arbitrary Propagation Angles

The equation for temporary evolution of spectral energy of collisionless Alfven waves is derived in framework of weak turbulence theory. The main nonlinear processes for such conditions are induced scattering and two quantum absorption of Alfven waves by thermal ions. The equation for velocity distribution of thermal particles is derived that describes diffusion in momentum space due to this nonlinear processes. Comparison is done with the results of another authors. Results obtained are qualitatively differ from the ones obtained for the case of Alfven waves propagation along mean magnetic field.Comment: 8 page
