Working paper
Lokshin M., Fong M. Policy Research Working Paper. WPS. World Bank Group, 2000. No. 2400.
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.

We study tunneling of charge carriers in single- and bilayer graphene. We propose an explanation for non-zero "magic angles" with 100% transmission for the case of symmetric potential barrier, as well as for their almost-survival for slightly asymmetric barrier in the bilayer graphene known previously from numerical simulations. Most importantly, we demonstrate that these magic angles are not protected in the case of bilayer and give an explicit example of a barrier with very small electron transmission probability for any angles. This means that one can lock charge carriers by a p-n-p (or n-p-n) junction without opening energy gap. This creates new opportunities for the construction of graphene transistors.

Estimates of the term structure of interest rates depend heavily on the quality of the market data from which it is constructed. Estimated rates can be incorrect because of observation errors and omissions in the data. The usual way to deal with the heteroscedasticity of observation errors is by introducing weights in the fitting procedure. There is currently no consensus in the literature about the choice of such weights. We introduce a non-parametric bootstrap-based method of introducing observation errors drawn from the empirical distribution into the model data, which allows us to perform a comparison test of different weighting schemes without implicitly favoring one of the contesting models – a common design flaw in comparison studies. We use government bonds from several countries with examples of both liquid and illiquid bond markets. We show that realistic observation errors can greatly distort the estimated yield curve. Moreover, we show that using different weights or other modifications to account for observation errors in bond price data does not always improve the term structure estimates, and often worsens the situation. Based on our comparison, we advise to either use equal weights or weights proportional to the inverse duration in practical applications.

This paper is devoted to denominal verb constructions (DNV construction, in a sense of [Gerdts & Marlett 2008]) in Chukchi language. The goals of this paper are twofold. The first aim is purely descriptive: we will clarify the description of morphosyntax and semantics of six affixal verbs which participate in the formation of DNVs in Chukchi, and also suggest a new way of analyzing the polysemy of these and other Chukchi affixal predicates. The second aim of the paper is to compare DNVs in Chukchi to the closely related phenomenon of Noun Incorporation in the same language. We will highlight the similarities between the two constructions and examine different approaches ([Mithun 1997], [Johns 2007], [Gerdts & Marlett 2008], [Muro 2008] and [Barrie 2006]) to the relationship between these phenomena. We will show that it is natural to analyze Chukchi DNVs as a result of the grammaticalization of noun incorporation construction (see [Mithun 1997] for the similar analysis for Salish and Wakashan languages).

In our recent paper we suggested a natural construction of the classical relativistic integrable tops in terms of the quantum R-matrices. Here we study the simplest case -- the 11-vertex R-matrix and related gl_2 rational models. The corresponding top is equivalent to the 2-body Ruijsenaars-Schneider (RS) or the 2-body Calogero-Moser (CM) model depending on its description. We give different descriptions of the integrable tops and use them as building blocks for construction of more complicated integrable systems such as Gaudin models and classical spin chains (periodic and with boundaries). The known relation between the top and CM (or RS) models allows to re-write the Gaudin models (or the spin chains) in the canonical variables. Then they assume the form of n-particle integrable systems with 2n constants. We also describe the generalization of the top to 1+1 field theories. It allows us to get the Landau-Lifshitz type equation. The latter can be treated as non-trivial deformation of the classical continuous Heisenberg model. In a similar way the deformation of the principal chiral model is also described.

We consider the isomonodromy problems for flat $G$-bundles over punctured elliptic curves $\Sigma_\tau$ with regular singularities of connections at marked points. The bundles are classified by their characteristic classes. These classes are elements of the second cohomology group $H^2(\Sigma_\tau,{\mathcal Z}(G))$, where ${\mathcal Z}(G)$ is the center of $G$. For any complex simple Lie group $G$ and arbitrary class we define the moduli space of flat bundles, and in this way construct the monodromy preserving equations in the Hamiltonian form and their Lax representations. In particular, they include the Painlev\'e VI equation, its multicomponent generalizations and elliptic Schlesinger equations. The general construction is described for punctured curves of arbitrary genus. We extend the Beilinson-Drinfeld description of the moduli space of Higgs bundles to the case of flat connections. This local description allows us to establish the Symplectic Hecke Correspondence for a wide class of the monodromy preserving equations classified by characteristic classes of underlying bundles. In particular, the Painlev\'e VI equation can be described in terms of ${\rm SL}(2, {\mathbb C})$-bundles. Since ${\mathcal Z}({\rm SL}(2, {\mathbb C}))= {\mathbb Z}_2$, the Painlev\'e VI has two representations related by the Hecke transformation: 1) as the well-known elliptic form of the Painlev\'e VI (for the trivial bundles); 2) as the non-autonomous Zhukovsky-Volterra gyrostat (for non-trivial bundles).

This paper proposes a multidisciplinary approach to understanding the future perspectives of climate change. First, it analyzes the possibilities of using the media as an information source for anticipating trends and challenges in this area through exploring the topics that have been actively discussed in the news in the recent 5 years. Second, qualitative and quantitative approaches are combined in this study in order to identify trends of different categories: social, technological, economic, environmental, political and values/culture. It allows integrating the results of trends monitoring obtained from qualitative and quantitative sources and create a complex map of trends. Qualitative approach is based on the literature review and consultations with the experts, while quantitative analysis includes collecting the news from Factiva database and processing it in Vantage Point software using bibliometric analysis, natural language processing, statistical analysis and principal component analysis. The results shown that 58% of trends were validated by the news and its contribution to the final trends list accounts for 25% on average, which means that the media can be considered as a useful additional data source for validating and updating trends. The results of this multidisciplinary study can be of interest to researchers, economists, business representatives and policy makers that are involved in the climate change related activities.
