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.

The collapse of the USSR and structural changes in society gave rise to family and marriage transformations in Russia and other post-Soviet countries of Eastern Europe. Estonia is among the examples of rapid marriage transformation and the spread of cohabitations and extramarital births. At the same time, throughout the post-war era Estonia accepted Russian migrants. Studies show that the adaptation of the Russian population in Estonia proceeds slowly, and that patterns of matrimonial behavior among the Russian migrants and their descendants in Estonia are closer to patterns of ethnic Russians in Russia. In this study, the Generation and Gender Survey data for Russia (2004) and Estonia (2005) were used to analyze the prevalence of first and second childbirths in first and higher-order unions and the determinants of fertility after repartnering among the Russian and Estonian populations in Estonia and Russians in Russia. We consider the impact of partners’ age and parenthood status at the beginning of higher-order unions, as well as social variables (e.g. education, type of settlement and ethnicity).  The results show that the contribution of higher-order unions to total fertility increased significantly in all studied populations. However, first childbirths in high-order unions are rare among both the Russians and the Estonians, second births after repartnering are more widespread among Russians in Russia. Divorces and separations significantly increase the interval between first and second births, but there is no difference in time interval duration between the three considered population groups. The determinants of childbearing among Russians in Russia and Estonia in higher-order unions are very similar: they are the age of women, the type of habitation and the initial nature of the union. The effect of the parenthood status and marriage cohort is individual for each population group: in Russia, if a male partner has no child(ren) from previous relationships, the couple has a higher chance of having a mutual child. The probability of childbearing after repartnering significantly increased in 1990-1999 in Estonia.

The authors model the household demand for child care, the mother's participation in the labor force, and her working hours in Romania. Their model estimates the effects of the price of child care, the mother's wage, and household income on household behavior relating to child care and mothers working outside the home. They find that: Both the maternal decision to take a job and the decision to use out-of-home care are sensitive to the price of child care. A decrease in the price of child care can increase the number of mothers who work and thus reduce poverty in some households. The potential market wage of the mother has a significant positive effect on the decision to purchase market care and the decision to engage in paid employment. The level of household nonwage income has little effect on maternal employment and the demand for child care. In addition to facilitating women's work, kindergartens and cr�hes appear to provide educational and social benefits for children. Close to half the children in these facilities have mothers who do not work. Further research is needed to assess the cost and nature of these benefits and to determine the appropriate roles for the private and public sectors in providing, financing, and regulating such services for working and nonworking mothers.

The article reviews the narratives on childhood in medieval autobiographical writings. It argues that these narratives allow us both to see differences in perception of childhood between medieval and modern autobiographers and to rethink the well-known argument of historians of childhood that medieval culture was indifferent to the first years of human life.

This working paper is based on the results of a study of the child-rearing practices of Russian-speaking women in the context of a migration perspective focusing on their migration experience, language, and other features that are perceived as cultural and an integration context as determining many important aspects of child-rearing. The analysis shows that a mother’s choice of structured activities for the child can be caused by structural factors, such as the national peculiarities of the system of school and pre-school education, family policy, the specifics and set of programs offered at schools and available in the area. Regardless of the social segment, in which migrants are incorporated, children begin to prefer speaking Spanish than Russian if there is not any special effort from the adults. This leads to the fact that the study of the Russian language in some families affects all spheres of life, and many aspects of child-rearing. Many women develop and share ideas about the differences in the parenting approach and style of women from the post-Soviet space and from Spain. Women perceive the stylistic features of the behavior of Russian women as highly demanding and share the view of the low demands of Spanish parents, yet differ in how they perceive their level of responsiveness to them.

The article is drawn on a study of the families of migrants, having school-age children, from Central Asia. The transnational practices of migrants are closely tied to integration processes, and this is reflected in generational differences. In some families, children that, unlike their parents, go or used to go to a Russian school, try to distance themselves from their parents’ generation, refuse to identify with it, and do not want to speak the native language of their parents. In some ways, these trends are a consequence of parentage practices that orient children toward the local social milieu and encourage the use of Russian. Despite the significance of transnational practices in the life of migrant families, the outcome of the study demonstrates the importance of examining the intergenerational dynamics in the incorporation process.

This research studies the child-rearing strategies of Russian-speaking women who live in Madrid by focusing on their children's participation in structured activities. The study answers the following questions: what attitudes to structured activities do the women have, what determined their choice of structured activities, what are the differences in such choices between working-class and middle-class families? The results are based on semi-structured interviews with Russian-speaking women (26 interviews) whose children attend after- or pre- school programs for Russian children, as well as with the teachers or coordinators of these programs (4 interviews). The findings make it possible to formulate conclusions that the class differences in the activities of children are determined by structural factors rather than the cultural logics of parents. All parents reproduce the idea that organized activity has a beneficial effect on a child's development, although they differ in their views on what kind of activities can bring benefits.

Recent research indicates that behavioral problems may lead to low academic performance. The present study is aimed to discover, what differences exist between primary school students who meet a sufficient number of ADHD (Attention Deficit Hyperactivity Disorder) criteria and those who do not experience any behavioral problems, in terms of academic achievements in reading and mathematics, annual progress in these subjects and personal, social and emotional development, based on the Russian sample of first-graders. This paper is a part of Russian iPIPS project and the instruments developed as part of this study were used. The sample consists of 3021 first-graders from two big regions of the Russian Federation. The results showed significant differences in both cognitive and social-emotional development but no differences in annual progress. The absence of differences in progress means that the development of children with behavior problems within the school system goes with the same speed but from the lower start level compared to other children. The results of the study provide important knowledge for the teachers and open a large area of further investigations in the field of ADHD in Russian school settings.

We use statistical data from 2000 to 2013 to compare the macro-level structure and the core institutions of the banking systems in China and Russia. Our main hypothesis is that, differences in the absolute size and socio-cultural features notwithstanding, these two systems are typologically similar. We consider the institutional structure, the market structure and concentration, the industrial policy of the government, and the banks' involvement in the financing of the non-financial economy. We find both similarities and differences, however in dynamics the trend towards convergence prevails. In both countries, we see a hierarchical multi-tier banking system headed by a few core state-controlled banks. These combine commercial activities with the activity of a development institution. Regardless of the nominal form of bank ownership, the government exerts influence on the lending decisions and market behavior of banks. We argue that the case of banking in China and Russia provides empirical proof to the macrosociological theory of institutional matrices [Kirdina, 2001]. We refer in particular to the needed proportion between the dominant and complementary institutions. Whereas China has been carefully seeking a sustainable balance, Russian in the 1990s grossly overshot with liberalization and now reverts to the underlying long-term trend. China has currently become Russia's institutional donor for Russia for innovations in the credit system design.

Throughout history Chinese artistic culture has developed a fairly complex system of diverse art forms and styles. Chinese export art, being created particularly to satiate constantly growing appetite of the Western world for Chinese goods, holds a specific place among them. In spite of being considered as insignificant in terms of artistic merits, nevertheless, Chinese export painting succeeded to cover a modest segment in the European market in the XVIII – XIX centuries. Unlike most other types of Chinese decorative and applied arts, Chinese export painting until recently has never been taken as a subject of scientific research. The collection of the National Library of Russia possesses a number of Chinese painting albums. Comprehensive study of these art works might bridge lacunas for research of other multitudinous kinds of Chinese export arts and crafts of the XVIII-XIX centuries.
