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

We propose a non-commutative generalization of Beilinson's Conjecture on the regulator map from algebraic K-theory to Deligne cohomology of algebraic varieties over Q. We also check a baby case of the generalized conjecture, namely, the case of finite-dimensional associative algebras.

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.

China’s initiative about “One Belt, One Road” could be treated ambiguously. On the one hand, it is intended to transform the newly acquired economic potential of that country into her higher status in the world. China invites a lot of nations to build up gigantic transit corridors by joint efforts, and doing so she applies productively her capital and technologies. International transactions in RMB are also being expanded. But, on the other hand, “One Belt, One Road” is also a necessity for China to cope with some evident problems of her current stage of development, such as industrial overcapacity, overdependence on imports of raw materials from a narrow circle of countries, and a subordinate status in global value chains. For Russia a participation in “One Belt, One Road” may be fruitful, since the very character of that project provides us with a space to manoeuvre. By now, Russian exports to China consist primarily of fuels and other commodities. More active industrial policy is needed to correct this situation. A flexible framework of “One Belt, One Road” is more suitable for this objective to be achieved, rather than traditional forms of regional integration, such as a free trade area.

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?

One major repercussion of the Russian-Georgian war of August 2008 was a significant increase in the EU‟s presence in Georgia. With the launch of the Eastern Partnership in May 2009, the deployment of an EU monitoring mis-sion in Georgia and the EU‟s participation in the Geneva talks, EU-Georgian relations appear to have entered a new stage. The war has also affected Geor-gia‟s foreign policy priorities with the EU acquiring a new significance at the same time as the prospect of NATO integration has become more uncertain. This paper reviews the evolution of EU-Georgian relations since Georgia‟s independence and asks whether the post-war context has brought a change in the nature of these relations. First, it analyzes the relations before the Rose Revolution and the nature of the EU‟s engagement in Georgia. Second, it ex-amines the changes after the revolution, focusing in particular on the diverg-ing expectations of the EU and Georgia. Finally, it asks whether the post-war context has brought more convergence between the two actors.

Economic growth in Russia in the first decade of this century almost doubled the country’s GDP but was accompanied by substantial reallocation of labor to the unregulated sector while formal employment was on gradual decline. The paper overviews evolution of the Russian labour market during the period of 2000-10 and discusses most general implications of informality to employment and earnings as well as the associated political economy challenges and consequences.

One of the most prominent in analytic philosophy is the so-called "Fregean Axiom", according to which the reference of a sentence is a truth-value. In contrast to this referential semantics, a use-based formal semantics will be constructed in which the logical value of a sentence is not its putative referent but the information it conveys. Let us call "Question Answer Semantics" (thereafter: QAS) the corresponding formal semantics: a non-Fregean many-valued logic, where the meaning of any sentence is an ordered n-tuple of yes-no answers to corresponding questions. A sample of philosophical problems will be approached in order to justify the relevance of QAS. These include: (1) illocutionary forces, and the logical analysis of speech-acts; (2) the variety of logical negations, and their characterization in terms of restricted ranges of logical values; (3) change in meaning, and ute use of dynamic oppositions for belief sets.

I study a career concerns model in which the principal obtains information about the agent’s performance from an intermediary (evaluator), whose interests diverge from those of the principal. I show that, while the evaluator’s bias leads to ex-post suboptimal decisions regarding the agent (e.g., inefficient promotion or dismissal), it incentivizes the agent to exert more effort. As a result, generally, a non-zero bias is optimal. The optimal bias is “anti-agent” (“pro-agent”) when the agent is of high value (low value) for the principal from the ex-ante perspective. The magnitude of the optimal bias is increasing in the strength of the agent’s career concerns and decreasing in the degree of uncertainty about the agent’s ability. I also obtain that delegating decision rights to the evaluator may be preferred to communication when a sufficiently large bias is required to create incentives. I discuss applications of my results to promotion policies in organizations, evaluation of government programs and evaluation of CEOs by boards of directors.

The paper discloses a new approach to emerging technologies identification, which strongly relies on capacity of big data analysis, namely text mining augmented by syntactic analysis techniques. It discusses the wide context of the task of identifying emerging technologies in a systemic and timely manner, including its place in the methodology of foresight and future-oriented technology analysis, its use in horizon scanning exercises, as well as its relation to the field of technology landscape mapping and tech mining. The concepts of technology, emerging technology, disruptive technology and other related terms are assessed from the semantic point of view. Existing approaches to technology identification and technology landscape mapping (in wide sense, including entity linking and ontology-building for the purposes of effective STI policy) are discussed, and shortcomings of currently available studies on emerging technologies in agriculture and food sector (A&F) are analyzed. The opportunities of the new big-data-augmented methodology are shown in comparison to existing results, both globally and in Russia. As one of the practical results of the study, the integrated ontology of currently emerging technologies in A&F sector is introduced. The directions and possible criteria of further enhancement and refinement of proposed methodology are contemplated, with special attention to use of bigger volumes of data, machine learning and ontology-mining / entity linking techniques for the maximum possible automation of the analytical work in the discussed field. The practical implication of the new approach in terms of its effectiveness and efficiency for evidence-based STI policy and corporate strategic planning are shortly summed up as well.

  We study which Big Five personality traits are associated with academic performance among a sample of Russian university students using results from the Unified State Examination (for university admissions) and their current grade point averages as measures of academic performance. We find that Introversion, Agreeableness, Neuroticism, and Openness to experience have observable ties to academic performance. Those results partially confirm existing international studies, but our findings are notable for the relative unimportance of  conscientiousness for success in our Russian sample. We suggest that cross-cultural differences  in educational environment may explain why this trait seems less obviously important in the analysis.

We prove that a finite group acting by birational automorphisms of a non-trivial Severi-Brauer surface over a field of characteristic zero contains a normal abelian subgroup of index at most 3. Also, we find an explicit bound for orders of such finite groups in the case when the base field contains all roots of 1.

We study birational projective models of M_2,2 obtained from the moduli space of curves with nonspecial divisors. We describe geometrically which singular curves appear in these models and show that one of them is obtained by blowing down the Weierstrass divisor in the moduli stack of Z-stable curves \bar{M}_2,2(Z) defined by Smyth. As a corollary, we prove projectivity of the coarse moduli space \bar{M}_2,2(Z).

We study the complexity of birational self-maps of a projective threefold X by looking at the birational type of surfaces contracted. These surfaces are birational to the product of the projective line with a smooth projective curve. We prove that the genus of the curves occuring is unbounded if and only if X is birational to a conic bundle or a fibration into cubic surfaces. Similarly, we prove that the gonality of the curves is unbounded if and only if X is birational to a conic bundle.

According to the classical theorem, every irreducible algebraic variety endowed with a nontrivial rational action of a connected linear algebraic group is birationally isomorphic to a product of another algebraic variety and the s-dimensional projectice space with positive s. We show that the classical proof of this theorem actually works only in characteristic 0 and we give a characteristic free proof of it. To this end we prove and use a characterization of connected linear algebraic groups G with the property that every rational action of G on an irreducible algebraic variety is birationally equivalent to a regular action of G on an affine algebraic variety.
