We calculate determinants of weighted sums of reflections and of (nested) commutators of reflections. The results obtained generalize the matrix-tree theorem by Kirchhoff and the Pfaffian-hypertree theorem by Massbaum and Vaintrob.
The main focus of this paper is the relation between the realisation of the right of the child to express his/her views and democracy in Russia. With this in view, I will study the interconnection between the right to express the views and the right to participate. Further, I will give an overview of the specifics of democracy in Russia, how they influence political participation, and what could be done to prevent the further infantilisation of citizens in Russia. Finally, I will explore traditional perceptions with regard to children’s participation in Russia and the legal framework and practice of the implementation of the child’s right to social and political participation.
This article considers the model of metaphorical transfer of names of natural (atmospheric) phenomena. The worn inner form of many metaphors needs to consult the diachronic aspect, which allowes us to determine the conceptual transfer vector - the emotional attitude of speakers to natural phenomena, deterministic fear of them, faith in their supernatural origin.
The article deals with current approaches to research on social-economic impacts of cultural events. A systematic approach is proposed to analysis of services provided within cultural events in behalf of different target groups — stakeholders.
The distractive effects on attentional task performance in different paradigms are analyzed in this paper. I demonstrate how distractors may negatively affect (interference effect), positively (redundancy effect) or neutrally (null effect). Distractor effects described in literature are classified in accordance with their hypothetical source. The general rule of the theory is also introduced. It contains the formal prediction of the particular distractor effect, based on entropy and redundancy measures from the mathematical theory of communication (Shannon, 1948). Single- vs dual-process frameworks are considered for hypothetical mechanisms which underpin the distractor effects. Distractor profiles (DPs) are also introduced for the formalization and simple visualization of experimental data concerning the distractor effects. Typical shapes of DPs and their interpretations are discussed with examples from three frequently cited experiments. Finally, the paper introduces hierarchical hypothesis that states the level-fashion modulating interrelations between distractor effects of different classes.
This article describes the expierence of studying factors influencing the social well-being of educational migrants as mesured by means of a psychological well-being scale (A. Perrudet-Badoux, G.A. Mendelsohn, J.Chiche, 1988) previously adapted for Russian by M.V. Sokolova. A statistical analysis of the scale's reliability is performed. Trends in dynamics of subjective well-being are indentified on the basis the correlations analysis between the condbtbions of adaptation and its success rate, and potential mechanisms for developing subjective well-being among student migrants living in student hostels are described. Particular attention is paid to commuting as a factor of adaptation.
