Проблемы построения нелинейных регрессионных моделей в социологии: номинальные шкалы, синергетические эффекты, поиск эффективной системы предикторов
The article deals with а problem of nonlinear regression modeling in sociology: prevalence of variables measured on low type scales, inconsistency of quality parameters of the models, nonlinearity of modeled events, presence of latent interactions between studied variables and, finally, as a consequence, a problem of finding an effective system of predictors. The article contains suggestions to handle these problems.
In the age of globalisation which broadly means international interaction the idea of global communication comes to the front. Communicating globally implies using intercultural links and involves cultural knowledge of business counterparts as an integral part of global interaction. Language media being an essential tool of global interaction facilitate the process of business communication provided that certain guidelines are taken into consideration.
The complex phenomena of the individual creative activities as well as the historical development of scientific knowledge are under consideration from the point of view of the theory of self-organization (synergetics) in the book. Synergetics is characterized as a new research programme in a wide philosophical, cultural and historical context. The synergetical reinterpretations of some peculiarities of the creative thinking, such as the alternative ways and the scenarios, the latent attitudes and the predeterminations, the self-completing of whole images, are proposed here. The synergetical view of historical development of scientific knowledge is compiled in the book from the notions of the principal nonlinearity and cyclic character of science development,the inertia of the paradigmal consciousness in science, the value of marginal and archaic elements in science. For readers who are interested in evolutionary epistemology and the philosophical problems of synergetics.
In the frame of the third-order nonlinear wave dispersion theory the equation of motion of a vector wave packets mass center taken in to account arbitrary inhomogeneity profile is obtained. As short vector wave packets localized motion as infinite motion is shown. Short vector wave packets localizations area can be as bigger as smaller in comparison with long vector wave packets localizations area. The effect depend from third-order linear dispersion parameter.
The interaction of short single-component vector solitons in the frame of the coupled third–order nonlinear Schrodinger equations taking into account third–order linear dispersion, self–stepping, self–stimulated Ramanscattering, cross–stepping and cross–stimulated Raman-scattering terms is considered. Conditions of reflection and propagation of the solitons through each other and also the condition of oscillator interaction (vector breather) are obtained.
In the study presents an approach to the modeling power TWT with stopband sections on the basis of the theory of discrete electron-wave interaction. Designed TWT without the use of equivalent circuits of SWS and with use of local coupling impedance and the characteristic equation of degree four.
Propagation of the short vector envelope solitons in a inhomogeneous medium with linear potential in coupled third–order nonlinear Shrodinger equations frame is considered. Explicit vector soliton solution is obtained. The explicit solution for the solitons trajectories is studied. In particular cases this solitons solution can be reduced as to the short scalar soliton solution on linear inhomogeneity profile, as to well – known Chen soliton solution.
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.

This article is talking about state management and cultural policy, their nature and content in term of the new tendency - development of postindustrial society. It mentioned here, that at the moment cultural policy is the base of regional political activity and that regions can get strong competitive advantage if they are able to implement cultural policy successfully. All these trends can produce elements of new economic development.
