Seventeen papers, originally presented at a conference held in honor of Erik Thorbecke at Cornell University in October 2003, highlight the depth and breadth of Thorbecke's influence in research and policy on poverty, inequality, and development. Papers discuss the growth and roots of Erik Thorbecke's career; the consistency of poverty lines; poverty indices; whether poverty and inequality measures should be combined; an approach to measuring health inequality in India; household investments in education and income inequality at the community level in Indonesia; poverty traps and safety nets; progress in the modeling of rural households' behavior under market failures; labor laws and labor welfare in the context of the Indian experience; macro models and multipliers; multiplier effects and the reduction of poverty; developing an accounting matrix for the euro area; globalization, economic reform, and structural price transmission--social accounting matrix decomposition techniques with an empirical application to Vietnam; institutions, factor endowment, and inequality in Ghana, Kenya, and Senegal; an optimal nonlinear taxation approach combining incentives, inequality, and the allocation of aid when conditionality doesn't work; agricultural research and policy to achieve nutrition goals; and whether dualism is worth revisiting.

This paper presents a new integration technique for time-domain simulation of nonlinear electronic circuits. The new technique exploits A-stable single-step integration methods of order 1 up to 4 obtained by applying the Obreshkov formula to charge oriented circuit equations. The predictor-corrector algorithm exploited in the transient analysis for solving the initial value problem is described. The numerical examples of time-domain simulation are given which demonstrate the numerical accuracy and efficiency of the proposed technique.
Management in Russia is as difficult to define as a profession as it is in other countries, and the question of what education is appropriate for a future manager is also difficult to define. Business schools in russia need to think more carefully about their curriculums and about what they should be preparing their students for.
Today we could admit the growing demand for high educated experts, but modern technologies provide not only new learning opportunities, but also enormous amount Web-resources to plagiarize. In this paper we try to investigate role of intrinsic motivation on attitude towards plagiarism. Some results received during a project “A cross-cultural study of a new learning culture in Germany and in Russia” concerned intrinsic motivation of ITstudents and attitude to plagiarize are discussed. Analysis showed absence of significant differences in intrinsic motivation and significantly more tolerance of Russian students to plagiarism. We presented analysis of reasons for plagiarism and probable ways to solve with this problem in educational practice.
The article is concerned with results of content analysis of textbooks for high school in the area of social and human sciences. The author uses the typology of values introduced by S. Schwartz which consists of two value axes — “conservation — openness to change” and “selfassertion — caring about people and nature” — and describes values that underlie each subject area and then compares these values with results of mass surveys of the values of Russians.
The objective of this paper is to estimate the factors of intergeneration educational mobility in Russia and Soviet Union, that is to test the equality in accessing the continuation of education at the next level for children from different social groups (families with various levels of the family capital), estimated for different cohorts. The data source is Russian Longitudinal Monitoring Survey (RLMS-HSE) in 2006-11. There are panel data collected in 1994-2011. The sample is representative for Russia population as a whole. In 2006 there were some questions about respondent parents, that allow us to test if there is the dependence between educational level of respondent and some parameters of his/her parents, including their educational level, Communist Party membership and several other.
We estimated the model of probability to get the education of the given level depending on gender, age, nationality, characteristics of parents and birthplace for Russian people born in 1946-1990. Data about respondents' education are collected in 2006-11, about their parents - in 2006. The method of this model estimation is multinomial regression. The model was estimated for the pooled sample, as well as for three cohorts separately: born in 1946-60, 1961-75, 1976-90. It was found out that the family capital (first of all, the educational level of parents and urbanization level) represent an essential obstacle for educational opportunities of Russian high schools graduates. Regression estimation for the pooled sample demonstrates the significant level of dependence of respondents' education on that of their parents.
How are professors paid? Can the "best and brightest" be attracted to the academic profession? With universities facing international competition, which countries compensate their academics best, and which ones lag behind? Paying the Professoriate examines these questions and provides key insights and recommendations into the current state of the academic profession worldwide. Paying the Professoriate is the first comparative analysis of global faculty salaries, remuneration, and terms of employment. Offering an in-depth international comparison of academic salaries in twenty-eight countries across public, private, research, and non-research universities, chapter authors shed light on the conditions and expectations that shape the modern academic profession. The top researchers on the academic profession worldwide analyze common themes, trends, and the impact of these matters on academic quality and research productivity. In a world where higher education capacity is a key driver of national innovation and prosperity, and nations seek to fast-track their economic growth through expansion of higher education systems, policy makers and administrators increasingly seek answers about what actions they should be taking. Paying the Professoriate provides a much needed resource, illuminating the key issues and offering recommendations.

Also preconditions for diversification of state power in the field of civic identity forming are determined.
Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The lower bound of the probability of erroneous decoding is given. Examples of the dependence of the probability of erroneous decoding on the input error probability are given and the behavior of the obtained curves is explained.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
