This paper adds to the literature on banking in transition with regard to the comparative efficiency of public, private and foreign banks. We perform stochastic frontier analysis (SFA) of Russian bank-level quarterly data from 2005 to 2013. The method of computation of comparative cost efficiency is amended to control for the effect of the revaluations of foreign currency items in bank balance sheets. All public banks are split into the core and other state-controlled banks. We employ the generalized method of moments to estimate a set of distance functions measuring the observed differences in the SFA scores of banks and bank clusters, depending on the heterogeneity in risk preference and asset structure. These distance functions explain the changes in bank efficiency rankings. Our results on comparative bank efficiency are qualitatively different from those in mainstream papers. The efficiency scores of Russian banks are higher and less volatile, and spreads between the scores of different bank types are narrower than hitherto believed. Foreign banks appear as the least cost-efficient type of market participants, while the core state banks are, on average, nearly as efficient as domestic private banks. We suggest that foreign banks are capable of being more cost efficient than others if they increase loans-to-assets ratios above the sample median level. Core state banks, conversely, lead in terms of cost efficiency if their loans-to-assets ratio falls below the sample median level. Our approach is potentially applicable to the analysis of bank efficiency in other dollarized emerging markets.

This paper adds to the literature on banking in transition with regard to the comparative efficiency of different bank groups. We conclude that, to prevent the distoring effect of currency and securities revaluations, a refined definition of bank revenue is proper in comparative bank efficiency computations for countries with substantial volatility in financial markets.

The paper examines how type of ownership affects the profit efficiency of Russian banks. Using bank-quarter data for selected banks in the period 2004–2015, we combine stochastic frontier analysis (SFA) methodology with an intermediary approach to assess profit efficiency. Our key findings show that foreign-owned banks are the most efficient, followed by state-owned banks and private domestic banks. We also find that the profit efficiency of foreign-owned banks was higher than that of other banks during the economically stable periods of 2004Q1 to 2008Q2 and 2014Q1 to 2015Q3, and that state-owned banks were more efficient than others in the period of financial turmoil from 2008Q3 to 2013Q4 thanks to state support. These results are robust when we consider these banks in terms of branch network diversity, risk preferences, and specialization.

There is a special type of corpora, a poetic corpus, which have a special metric markup. They allow us to do the study of poetry by the methods that are familiar to corpus linguistics in general. We have created the Bashkir poetic corpus. It allows us to answer some questions about the structure of the Bashkir poetry. Texts in the corpus are annotated with morphological tags, each single token having a set of tags, and with special metric tags, enabling search in lines of specific meter, in rhyming position, etc.

We get sufficient conditions for the full basic automorphism group of a complete Cartan foliation to admit a unique (finite-dimensional) Lie group structure in the category of Cartan foliations. In particular, we obtain sufficient conditions for this group to be discrete. Emphasize that the transverse Cartan geometry may be noneffective. Some estimates of the dimension of this group depending on the transverse geometry are found. Further, we investigate Cartan foliations covered by fibrations and ascertain their specification. Examples of computing the full basic automorphism group of complete Cartan foliations are constructed.

The basic values of the Russian population and the population of 31 European countries were compared with data obtained by the Schwartz Questionnaire, embedded into the fourth round of the European Social Survey. Conclusions about similarities and differences of basic human values between Russia and other European countries confirm the thesis that Russia is a country which shares a general logic of cultural and social development with the rest of the world and which has a lot in common with countries of a similar economic level and recent political history. In most value comparisons, Russia appeared to be closer to Post-Communist and Mediterranean countries than to Western European or Nordic countries. The fact that Russians are less committed than most Europeans to the values of caring, tolerance, equality, and ecology, and, conversely, more committed than most Europeans to the competitive “zero-sum” values of personal success, wealth, and power, confirms the validity of current moral criticisms of mass values and morals in Russia. The other disturbing fact is the relatively low commitment of Russians to the values of Openness to Change and, conversely, a strong focus on Conservation. So basic values of Russians create a cultural barrier to the development of an innovation-based economy and to the societal development as a whole. Thanks to a shift from country-level analysis to individual- and group-level analysis, we challenge the notion of the “average Russian” and demonstrate that the Russian value majority consists of two subtypes. Russia also has a sizable value minority and its members share values non-typical for most Russians. Two value minorities, which embrace 19% of the Russian population, are more committed to values of Openness and Self-Transcendence than the rest of the Russian population. These value groups are typical for European countries with more prosperous and happy populations and we can hypothesize that in Russia they are also resource groups for the country’s advancement.

The purpose of this article is to develop techniques for estimating basis log canonical thresholds on logarithmic surfaces. To that end, we develop new local intersection estimates that imply log canonicity. Our main motivation and application is to show the existence of Kahler-Einstein edge metrics on all but finitely many families of asymptotically log del Pezzo surfaces, partially confirming a conjecture of two of us. In an appendix we show that the basis log canonical threshold of Fujita-Odaka coincides with the greatest lower Ricci bound invariant of Tian.

Our study contributes to the debate on the interaction between academic context, individual achievement, and mathematics self-concept in schools. It is known that high-achieving peers positively influence the individual achievements of all group members. At the same time, it has been shown that the self-concept of students tends to decrease in the presence of high-achieving peers, as individuals make relative judgments of their abilities vis-à-vis their peer group. Stu-dents with mediocre performance feel more confident about their abilities in a group of poor achievers (the Big-Fish-Little-Pond Effect – BFLPE – introduced by H.Marsh). On the other hand, perceived prestige of a school enhances the self-confidence of students as people tend to “bask in the glory” of others (the “reflected glory” effect). We test the two effects mentioned above – BFLPE and the “reflected glory” effect. We hypothesize that both effects are stronger in highly stratified education systems where there is a stronger explicit difference between high- and poor-achieving students, and schools are ranked by their prestige. We compare the interac-tion of academic context, achievement, and mathematics self-concept in stratified (Russia and Czech Republic) and non-stratified (Norway and Sweden) educational systems on the TIMSS’07 database using HLM7. Our study shows: 1) an absence of BFLPE for all four countries, i.e. the achievement of others is positively related to an individual’s math self-concept; 2) strong support for the “reflected glory” effect is found only in stratified educational systems; and 3) greater pos-itive effect on self-concept for students with poor achievement who study in the best schools.

Exploring Bass' Triangulability Problem on unipotent algebraic subgroups of the affine Cremona groups, we prove a triangulability criterion, the existence of nontriangulable connected solvable affine algebraic subgroups of the Cremona groups, and stable triangulability of such subgroups; in particular, in the stable range we answer Bass' Triangulability Problem is the affirmative. To this end we prove a theorem on invariant subfields of $1$-extensions. We also obtain a general construction of all rationally triangulable subgroups of the Cremona groups and, as an application, classify rationally triangulable connected one-dimensional unipotent affine algebraic subgroups of the Cremona groups up to conjugacy.

It was shown in our previous paper that quantum ${\rm gl}_N$ $R$-matrices satisfy noncommutative analogues of the Fay identities in ${\rm gl}_N^{\otimes 3}$. In this paper we extend the list of $R$-matrix valued elliptic function identities. We propose counterparts of the Fay identities in ${\rm gl}_N^{\otimes 2}$, the symmetry between the Planck constant and the spectral parameter, quasi-periodicities with respect to these variables, the Kronecker double series representation of the R-matrix. As an application we construct $R$-matrix valued $2N^2\times 2N^2$ Lax pairs for the Painlev\'e VI equation (in the elliptic form) with four free constants using ${\mathbb Z}_N\times {\mathbb Z}_N$ elliptic $R$-matrix. More precisely, the four free constants case appears for an odd $N$ while even $N$'s correspond to a single constant.

The working paper represents a study of motherhood as a specific semantic construct in contemporary Russia. The author analyses the ways in which knowledge about motherhood produces specific maternal experience. The general theoretical framework is the foucauldian concept of discursive power based on knowledge. At the same time, motherhood is viewed as a class differentiated practice. The primary focus of the analysis is motherhood as experienced by Russian middle class women. The paper discuss how motherhood is discursively produced in the Russian context. The author is interested in the knowledge and discourses that Russian middle class women employ in order to become aware of their motherhood and describe themselves as mothers. The paper describes critical sociological theories of motherhood connecting this phenomenon to such concepts as power, social order and social inequalities. These critical approaches deconstruct the motherhood discourse and reveal that the mother becomes a point of production of social and political order of the modern societies. The analysis of the Russian discourse on motherhood in the political and cultural context is presented by the author as well. The paper elaborates upon the category of “responsibility” as the primary meaning component of middle class motherhood. In the conclusion the issue of why and when Russian mothers are considered “responsible” is discussed

The aim of this study is to compare the sociodemographic events marking the transition to adulthood in France, Estonia and Russia: first leaving parents, completion of education, first partnership, first marriage and first childbirth. We used the first waves of the Generations and Gender Survey for these three countries and an advanced method – Sequence Analysis. According to the Second Demographic Transition Theory, we expected a convergence in the sequencing, timing and tempo of the occurrence of target events. The results showed the slow convergence of sequences, but not of timing and tempo. Estonia and Russia are still close in the timing of the occurrence of events, but in tempo Estonia and France are more alike. The ages at which people start families in Estonia and Russia have decreased in younger generations in comparison with older ones, despite our expectation that they would increase. For the youngest generation (1970s), the time between leaving parents and becoming a parent is 5-7 years in France, 4-6 years in Estonia and 2-3 years in Russia. The sociodemographic behaviour of Estonians clearly positions them between Europe and Russia. Thus, the comparison of France, Estonia and Russia only partially confirms the Second Demographic Transition Theory.

This paper focuses on a subway user, one of the main characters of mundane mobility in big cities. It is based on the field research conducted by the author in two Russian cities (Moscow and Kazan) in 2013-2014. The subway is considered not only as public transportation, but more broadly as a regulation tool that is used by homo mobilis to construct a wide network of relationships: with the city, with time, with one's daily activities. The notion of “affect management” - the urbanite's ability to manage their own emotional states and experiences - is suggested to describe the role of the subway in everyday life planning

Schang F. The Right to Believe: Perspectives in Religious Epistemology. ISBN 9783868381320. Ontos Verlag, 2012
An argument for the rationality of religious belief in the existence of God is defended. After reviewing three preconditions for rational belief, I show reasons to privilege the criterion of consistency. Taking the inconsistency of the religious belief in God and the belief in the scientificworld picture as the impediment to a rational belief in God, I propose that we can overcome thisobjection by assuming, firstly, that God is a universal class. This allows us to put the problem of God in set-theoretic terms, such that the antinomy that follows from such an assumption can beovercome by assuming that God is not a subject but a strict class that cannot be individuated. I conclude that that the self-contradictory nature of God does not prevent the believer from making arational, ethical assessment that the contradiction resides in the possibility of using language toexplain his existence, but that this does not make belief in the existence of God unjustifiable – onthe contrary. In this way, we can say statements that claim God exists are justifiable.

The paper shows relationships between characteristics of residents and places where they live. A combination of three criteria of place attractiveness (retention and attraction, conditions for natural growth, and settling) was chosen to classify place market segments, and profiles of beneficiaries for all the segments on the theoretical level were built. The results of the empirical study partially confirm developed theoretical typologies. Two methods to segment place market are equal only if expectations of population are constant. Study results allow place marketers to identify emerging shifts in the structure of beneficiaries of specific places and predict their further evolution.

The main idea of this paper is that some sort of legal theory dealing with the law’s social impact is an indispensable element of the legal profession in the time of late modernity. Can legal theory provide an adequate understanding of the social context of the application of law, relying solely on internal resources? If not, which interdisiplinary discourse is the best and why?
