Существование и устойчивость периодических решений уравнения реакция-диффузия в двумерном случае
No full textParabolic singularly perturbed problems have been actively studied in recent years in connection with a large number of practical applications: chemical kinetics, synergetics, astrophysics, biology, and so on. In this work a singularly perturbed periodic problem for a parabolic reaction-diffusion equation is studied in the two-dimensional case. The case when there is an internal transition layer under unbalanced nonlinearity is considered. The internal layer is localised near the so called transitional curve. An asymptotic expansion of the solution is constructed and an asymptotics for the transitional curve is determined. The asymptotical expansion consists of a regular part, an interior layer part and a boundary part. In this work we focus on the interior layer part. In order to describe it in the neighborhood of the transition curve the local coordinate system is introduced and the stretched variables are used. To substantiate the asymptotics thus constructed, the asymptotic method of differential inequalities is used. The upper and lower solutions are constructed by sufficiently complicated modification of the asymptotic expansion of the solution. The Lyapunov asymptotical stability of the solution was proved by using the method of contracting barriers. This method is based on the asymptotic comparison principle and uses the upper and lower solutions which are exponentially tending to the solution to the problem. As a result, the solution is locally unique.The article is published in the authors’ wording.Параболические сингулярно возмущенные задачи активно исследуются в последние годы в связи с большим количеством практических применений: химическая кинетика, синергетика, астрофизика, биология и т.д. В этой работе исследуется сингулярно возмущенная периодическая задача для параболического уравнения реакция-диффузия в двумерном случае. Рассматривается случай существования внутреннего переходного слоя при несбалансированной нелинейности. Внутренний слой локализован вблизи так называемой кривой переходного слоя. Cтроится асимптотическое разложение решения и определяется асимптотика для кривой переходного слоя. Асимптотическое разложение состоит из регулярной части, внутреннего слоя и части пограничного слоя. В этой работе мы сфокусируем внимание на части внутреннего переходного слоя. С целью его описания вводится локальная система координат в окрестности кривой перехода и используются растянутые переменные. Чтобы обосновать таким образом построенную асимптотику, используется асимптотический метод дифференциальных неравенств. Верхнее и нижнее решения строятся путем достаточно сложной модификации асимптотического разложения решения. Асимптотическая устойчивость решения по Ляпунову доказывается с помощью метода сужающихся барьеров. Этот метод базируется на принципе дифференциальных неравенств, и в нем используются верхнее и нижнее решения, которые экспоненциально стремятся к решению задачи. Как результат, решение является локально единственным.Статья публикуется в авторской редакции
Поэтика народнического травелога конца XIX века (путевые очерки Ф. Д. Нефедова)
No full text462The article deals with the late stage of the Narodnik?s (populist) fiction of early 1890-s in the aspect of deep cognition of Russia, which was important on the turn of the century. The subject matter is the travel essays of the writer-ethnographer F.D. Nefedov, who is forgotten nowadays. The article describes some features of the poetics of the Narodnik?s travelogue (the narrator, the compositional principle of contrast a conflict within a single scene, etc.), the originality of the demonstration of the author?s position and synthetical genre structure. According to the type of the plot construction Nefedov?s travelogue is close to a story. His plot is not only localy attached to a certain scene or a situation, but also contains the idea which is expressed in the attempts of the privileged class characters to get closer to the ordinary people, but their realization remains outside the plot. The poetics of Nefedov?s travel essays reflects both the ideological position of the author an

Russia’s Modern Banking Law
No full textIn this study, the author offers a very general review of banking legislation in Russia. The author discusses the main statutory acts which regulate banking activity and the Central Bank of the Russian Federation (Bank of Russia). The author describes the Bank of Russia’s functions. He concludes that, in modern market conditions, it is extremely important to develop civil regulation and reduce administrative regulation; however, he finds that, unfortunately, the Bank of Russia is still subject to administrative management. Considering the nature of the relationships between the Bank of Russia and private credit organizations, the author insists on the need for a partnership, forged on principles of dispositive regulation, between them. More generally, this work considers the problems of domestic financial regulation through the theoretical prism of free banking. Current Russian banking legislation only focuses on the creation of the best mechanism for the organization of credit and financial relationships. The author considers not only the requirements for state financial policy, but also the interests of private credit organizations, which serve as the engine of the financial market and strengthen the banking system as a whole. Until recently, many aspects of the Russian banking system have been a compromise between the old and new conceptions of the economy. For this reason, the upholding of free market ideas is essential in order to develop banking legal theory. The author criticizes the emerging tendency to reduce the role of liberal financial institutions, such as the increasing role of the Bank of Russia as a mega-regulator. Considering this, the author recommends the application of immediate counteractions against the above-described tendency and supports the strengthening of the independence of credit organizations. He emphasizes that this is the only approach to fully develop the existing banking system.In this study, the author offers a very general review of banking legislation in Russia.

A Theory of Demographic Cycles and the Social Evolution of Ancient and Medieval Oriental Societies (translation)
No full textA theory of demographic cycles is developed by the author out of the contributions of many sciences. F. Braudel named these cycles as "secular trends," and R. Cameron used the concept of "logistics cycles." The author constructs a mathematical model of a demographic cycle. With the help of this model the cycle is divided into phases for which the author is able to determine about 40 qualitative attributes of the cycle. These attributes allow a demographic cycle to be identified in the real course of a history even in the absence of quantitative data about a population. With the help of this method 57 demographic cycles are identified in the history of the various countries of the East. In particular, it is shown that the increase of demographic pressure at the end of a cycle results in establishment of étatist monarchy
TUI tipų lyginamasis vertinimas ES-14 ir Vidurio bei Rytų Europos šalyse.
No full textThe main purpose of this master thesis is to determine types of foreign direct investments (FDI) in two distinct parts of the European Union (the EU): in 14 countries that were part of the union in 1995 (EU-14) and 8 new member states in Central and Eastern European (CEE) region that joined in 2004. Master thesis consists of three parts: the analysis of the literature, research and its results, a conclusion and recommendations. Literature analysis focused on review of the theories that led to the development of the FDI, application of them in this work, as well as overview of previous research on the FDI determinants in the CEE region. The author defined proxy variables such as GDP, inflation, wage rate, education and resource rents that acted as representatives of certain types of FDI. Following literature analysis, the author applied defined panel data model to carry out the research into FDI determinants in two regions. After calculations were done, the author found out that FDI in EU-14 countries is mainly positively influenced by GDP per capita, while for CEE region rising wages is negative factor and inflation rate has positive influence. Conclusions were made that the EU, although acting like joint economic union, is not homogenous in attracting FDI. The countries of EU-14 region have shown specialization in market-seeking FDI and CEE region in efficiency-seeking type. The natural resource seeking FDI does not have standing in either of regions and asset-seeking FDI requires further research. Author believes that results of the study can be useful for more precise definition of governmental investment-seeking policies. During this work several research gaps were found, mainly in relationship of education and FDI, which author recommends to explore further
