Образовательные траектории школьников Ярославской области: дискриминантный анализ в сравнении с логистической регрессией
The article studies educational trajectories of schoolchildren in Yaroslavl Oblast. Conclusions point out that schoolchild’s educational achievements, educational plans of his/her friends and the level of education of his/her father are key predictors of a decision about continuing education. Thanks to this information it is possible to know which schoolchildren are at risk of not continuing their studies. In the course of the research comparative advantages of the logistic regression and the discriminant analysis in the case of binary dependent variables were examined. With the necessary prerequisites for the use of methods fulfilled, both strategies work well classifying schoolchildren.
The principal result of this research is that the valuable skills have a negative and significant effect on alcohol abuse. We found that a higher professional level is consistent with a stronger negative relationship between earnings and alcohol-related behaviors and problems. The explanation of the result is proposed in that the pecuniary losses imposed on an individual by alcohol-related physical inability are positively conditioned by the valuable skills.
The modern concept of modernizing Russia somehow reproduce the history of the theory of innovation. The theory of innovation in its development has gone through a least 3 stages. In the first phase (1910 - first half of the 40s) to the forefront issues of understanding the nature of innovation and their role in the development of society over time (long, medium and short periods), the relationship of innovation and long cycles conditions. This period is associated with the names of J.A.Schumpeter, M.I.Tugan-Baranovsky and N.D. Kondratieff. The second stage in the development of innovation theory (second half 1940 - first half of the 1970s) is characterized by the increased role of macroeconomic analysis, in turn, he has at least two substages: the first of which was dominated by the ideas of neo-Keynesians, on the second-neoclassical. The third stage of development of the theory of innovation began in the mid-1970s and proldolzhaetsya to the present. It is characterized by an offensive alternative approach to macroeconomic theory. With a certain degree of conditionality is also possible to distinguish two substages. The first (second half of the 1970s - early 1990s) is characterized by the emergence of new ideas drawn from evolutionary theory, institutionalism (the theory of the firm) and management (innovation management). In the second substage (mid 90s) innovations studied by the methods of systems analysis. The authors are increasingly focused on issues of comparative studies: a comparative analysis of innovation policy in different countries, study the ways and means of forming an effective innovation systems. In the report it is critically considered not only the official point of view, but also M. Porter, K. Ketels work “Competitiveness at the Crossroads: Choosing the Future Direction of the Russian Economy”. Also «The forecast of innovative, technological and structural dynamics of Russian economy till 2030» and RAND Corporation report “The Global Technology Revolution 2020: Trends, Drivers, Barriers, and Social Implications” are analyzed. In this paper institutional preconditions and possibilities of application of the concept of social market economy in the 21st century Russia were analyzed. Basic elements of social market economy are personal liberty, social justice, and economic efficiency.
Procedure for the simulation of the advances in EGE from mathematics is considered. For some tasks the important predictors are obtained. The models of binary logistics regression and ordinal regression for the prediction of probabilities of solution of task are built.
The article is focused upon business education students perceptions of career success and its determinants. Empirical base of research is formed by a survey of 222 business school students in the three Universities of Moscow, attending MBA, EMBA and DBA programs. The students are classified into five groups on the basis of their perceptions of success. These groups also differ by perceptions of success determinants, ethical principles and by motivation behind joining an MBA program.
People are the focus of the third edition of the OECD Yearbook, which looks at some of the key challenges that have resulted from over five years of global economic turmoil. OECD experts are joined by leaders from government, business, labour, academia and civil society to examine pressing questions.
Economic crisis started in 2008 forced companies in Russia to move from growth and expansion to reduction and restructuring. The article presents the main changes at top managers’ labor market from the beginning of crisis in Russia. The original data on top managers’ mobility in Russia from late 1999 till 2009 was used. The main result of the research is that there were no big changes in Russian top managers’ labor market during the crisis years (2008–2009). The most significant change was the increase of firm’s demand for specific human capital of top managers and the decrease of demand for general human capital.
We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.
