  We show that the derived category of any singularity over a field of characteristic 0 can be embedded fully and faithfully into a smooth triangulated category which has a semiorthogonal decomposition with components equivalent to derived categories of smooth varieties. This provides a categorical resolution of the singularity.

This paper examines determinants of corruption across Russian regions. Key contributions include: (i) a formal study of economic corruption determinants across Russian regions; (ii) comparisons of determinants of perceived corruption versus those of actual corruption; and (iii) studying the influence of market competition and other factors on corruption. The re-sults show that economic prosperity, population, market competition and urbanization are significant determinants of Russian corruption. The use of alternative corruption measures reveals that economic prosperity and population have a largely similar impact on corrup-tion perceptions and corruption incidence. However, there are significant differences in the effects of competition and urbanization.

We propose a new method for assessing agents’ influence in network structures, which takes into consideration nodes attributes, individual and group influences of nodes, and the intensity of interactions. This approach helps us to identify both explicit and hidden central elements which cannot be detected by classical centrality measures or other indices.

The article suggests concept of chain generalized exchange proposed by Ekeh (1974) as a central concept underlying nonprofit marketing. Most studies and research perspectives are based on controversial concept of complex exchange (Bagozzi,1975) to be a central concept for nonprofit marketing. Article discusses limitations of complex exchange concept and offers chain generalized exchange to be a central concept of nonprofit marketing.

Nonprofit accountability in Russia is becoming increasingly important as nonprofit organizations become more open delivering more social services, public participation increases and third sector institutions evolve. In this paper authors demonstrate accountability in its different dimensions as it is shaped by the specific Russian social, economic and political environment. Supportive  empirical data available from the annual Monitoring of the State of Russian Civil Society is used to argue that Russian nonprofits face contradictions between “accountability for” and “accountability to” different stakeholders. These contradictions are a challenge requiring new legislation and behavioral ethics which could balance the sector’s heterogeneity.  In conclusion a two-tier regulatory framework is suggested.

 We consider the class C(T) of continuous real-valued functions on the circle. For certain classes of functions naturally characterised by the rapidity of decrease of Fourier coefficients we investigate whether it is possible to bring families of functions in C(T) into these classes by a change of variable. This paper was originally published in Matematicheskii Sbornik, 181:8 (1990), 1099--1113 (Russian). The English translation, published in Mathematics of the USSR, Sbornik, 70:2 (1991), 541--555, is to a large extent inconsistent with the original text. Herein the author provides a corrected translation.

This paper uses data from the Russian Longitudinal Survey that span the two recent economic recessions of 1998 and 2008 to study the effect of declining incomes on household composition. We hypothesize that individuals face a tradeoff between taking advantages of economies of scale and specialization when living with others and individual privacy. Consumption smoothing is achieved by forgoing privacy during a crisis and results in an increase in household size. Our empirical results suggest that members of the households that experienced negative income shocks are more likely to move in with others than households whose income remained the same or increased.

This study investigates the topical structure of the Russian-language blog-publishing service LiveJournal and the change in it that occurred in the course of the public activity after the State Duma elections in December 2011 as compared to a previous “control” period (November 27 – December 27 and August 15 – September 15 respectively). The data for both periods have been automatically obtained from 2000 top-rated blogs on the basis of ratings published by LiveJournal. Unsupervised topic modelling of the sampled posts was done using Latent Dirichlet Allocation algorithm. In December 2011 we found considerable growth in weights of all the topics closely associated with the discussion of voting results and protests, accompanied by a more moderate decrease in the majority of other social topics.The number of users who started posting texts that may be conventionally qualified as political according to LDA in December 2011, considerably outnumbers the number of those who ceased posting political items, which may indicate the existence of a blogger mobilization process in political topics.

This article analyzes changes in contemporary Latvian historical culture as regards the place it assigns to Baltic Germans in the country's past. During most of the twentieth century, their past presence in the region was represented as not really important. German noblemen and burghers were reckoned to the exploitative classes and, as such, received negative appraisal. After Latvia became independent from the USSR, German heritage came to be cherished as a symbol of Latvia’s Europeanness and a major attraction for international tourists, which is especially visible in Riga. In smaller towns, such as Koknese, partnership with a German town may originate from historic ties linking former Baltic Germans to the place, but this does not necessarily involve a historical policy emphasizing their positive presence in the history of the town. In the rural community of Irši, a transformation of the local historical culture largely takes place under the influence of the so-called ‘homesick tourists’ from Germany who come to visit the former German colony Hirschenhof that existed between 1766 and 1939.

The present article is motivated by the growing interest in the problem of trademark usage on the Internet and comparatively low interest in the problem of legal protection of other objects having factual distinctiveness. Despite the fact that differences in regulation of on-line and off-line trademark utilization have been recognized for a long period of time, there is still no harmonization in the field of other means of individualization among numerous Russian laws. Although recent research works are numerous, lawmakers haven’t still decided on how Internet has influenced on exclusive rights granted with the Chapter 76 of the Civil Code of Russian Federation. The issue at hand is affected by the significant growth of the Internet and electronic commerce. Moreover, problem discussed in present paper comes from the fundamental question of limits on the exercise of subjective civil rights. The aim of this paper is to analyze different types of means of individualization under Russian legislation; to show key aspects of usage and protection of the means of individualization on-line; to reveal the doctrinal theories stipulating emergence of new distinctive objects; to describe the current and potential pitfalls of legislative framework; and to demonstrate modern legal trends in the field. In addition, the paper suggests different steps and models of further regulatory development.

We explore the role and organizing capacity of foreign business associations (FBAs) in the Russian context. Considering the potential role of FBAs as effective intermediaries during time of aggravated international relations, the paper examines the problems and mechanisms of foreign firms’ interaction with key national partners in their host countries and describes the conditions that lead to effective dialogue between FBAs and national governments. The main phases and factors of evolution are identified for Russia’s two main channels of foreign firms’ collective actions: The Foreign Investment Advisory Council, which is chaired by Russia’s prime minister, and FBAs. A comparative analysis of the efficiencies of each channel finds that political, rather than economic or institutional, factors play the dominant role in explaining the shifting efficiency of collective action of foreign firms over time.

We prove that the characteristic foliation F on a non- singular divisor D in an irreducible projective hyperkaehler mani- fold X cannot be algebraic, unless the leaves of F are rational curves or X is a surface. More generally, we show that if X is an arbitrary projective manifold carrying a holomorphic symplectic 2-form, and D and F are as above, then F can be algebraic with non-rational leaves only when, up to a finite  etale cover, X is the product of a symplectic projective manifold Y with a symplectic surface and D is the pull-back of a curve on this surface. When D is of general type, the fact that F cannot be algebraic unless X is a surface was proved by Hwang and Viehweg. The main new ingredient for our results is the observation that the canonical bundle of the orbifold base of the family of leaves must be torsion. This implies, in particular, the isotriviality of the family of leaves of F .  ́

A polynomial with exactly two critical values is called a generalized Chebyshev polynomial. A polynomial with exactly three critical values is called a Zolotarev polynomial. Two Chebyshev polynomials $f$ and $g$ are called Z-homotopic, if there exists a family $p_\alpha$, $\alpha\in [0,1]$, where $p_0=f$, $p_1=g$ and $p_\alpha$ is a Zolotarev polynomial, if $\alpha\in (0,1)$. As each Chebyshev polynomial defines a plane tree (and vice versa), Z-homotopy can be defined for plane trees. In this work we prove some necessary geometric conditions for plane trees Z-homotopy, describe Z-homotopy for trees with 5 and 6 edges and study one interesting example in the class of trees with 7 edges.

We prove a Chekanov-type theorem for the spherization of the cotangent bundle ST∗B of a closed manifold B. It claims that for Legendrian submanifolds in ST∗B the property "to be given by a generating family quadratic at infinity" persists under Legendrian isotopies.

In this paper we calculate the ring of unstable (possibly non-additive) operations from algebraic Morava K-theory K(n) to Chow groups with ℤ(p)-coefficients. More precisely, we prove that it is a formal power series ring on generators c_i:K(n)→CH^i⊗ℤ(p), which satisfy a Cartan-type formula.

Generalizing the definition of Cartier, we introduce pn-typical formal group laws over ℤ(p)-algebras. An oriented cohomology theory in the sense of Levin-Morel is called pn-typical if its corresponding formal group law is p^n-typical. The main result of the paper is the construction of 'Chern classes' from the algebraic n-th Morava K-theory to every p^n-typical oriented cohomology theory.  If the coefficient ring of a p^n-typical theory is a free ℤ(p)-module we also prove that these Chern classes freely generate all operations to it. Examples of such theories are algebraic mn-th Morava K-theories K(nm)∗ for all m∈ℕ and CH∗⊗ℤ(p) (operations to Chow groups were studied in a previous paper). The universal pn-typical oriented theory is BP{n}∗=BP∗/(v_j,j∤n) which coefficient ring is also a free ℤ_(p)-module.  Chern classes from the n-th algebraic Morava K-theory K(n)∗ to itself allow us to introduce the gamma filtration on K(n)∗. This is the best approximation to the topological filtration obtained by values of operations and it satisfies properties similar to that of the classical gamma filtration on K0. The major difference from the classical case is that Chern classes from the graded factors gr^i_γ K(n)^∗ to CH^i⊗ℤ_(p) are surjective for i≤p^n. For some projective homogeneous varieties this allows to estimate p-torsion in Chow groups of codimension up to pn.
