dc.description.abstract

value: The subject of the article is financial position of leasing companies, parameters of its assessment and specificity of financial coefficients calculation. The purpose of the article is to develop, systematize and justify the limiting value of main parameters of leasing companies’ assessment that prepare statements in accordance with IFRS. The methodological basis was the systematization and analysis of theoretical and methodological approaches from the scientific works of Russian and foreign scientists and researchers on the economic analysis of leasing companies, and also the corresponding reporting standards. The main conclusion includes the fact that the leasing business has its own specifics and the transformation of the reporting of the leasing company for its subsequent analysis based on known generally accepted coefficients does not give a proper understanding of the financial situation of the leasing company. The article systematizes and describes the main parameters of leasing companies’ assessment. There is the author’s assessment model from the position of the creditor; the article describes the criteria values of the quantitative parameters of the assessment, as well as the qualitative ones. The methodology developed by the authors can be used by specialists working in different companies, which have leasing companies as counterparty. For example, the model can be applied by commercial banks while making decisions about lending of the borrowers — leasing companies. The valuation model presented in the article is a universal tool for assessing the financial and property situation of a leasing company outside of the link to a specific sector or branch of activity in the leasing market; it allows interested persons to evaluate the leasing company, its financial stability, financial position.

dc.description.abstract

value: The purpose of this article is to theoretically and practically solve the problem of different approaches to determining and applying the correct discount rate for investment design and business valuation purposes. As a result of applying the inversion method within the framework of a paired comparative analysis, basic principles of practical setting and application of an adequate and correct discount rate were revealed, namely: the principle of accounting for the temporary nature of alternative incomes, the principle of accounting for the nature of investments, the principle of determining management bifurcation points, and the principle of accounting for the nature of the discount. Eash of these causes a different, and often directly opposite, interpretation of the theoretical provisions of lost profits, depending on the scope application of the discount rate. The theoretical premises were fully confirmed by methodological analysis of one of the most popular models of setting the discount rate, CAPM. The results of research are not only of theoretical and methodological importance, but also of high practical importance. Their scope is not limited to the use of a discount rate approach: the results of this study can and should be applied in all cases when there is the question of quantifying the coefficients of reduction in applied investment and economic calculations.

dc.description.abstract

value: The problem of low pay for school teachers has a long history, but despite all legislative initiatives, this problem is still far from being solved. The aim of the work is to prove that the wage standards of teachers in 2013–2017 have not been met and an analysis of the its regional differentiation, taking into account the level of economic development of the region. The article describes the basic teacher pay indicators that are presented in open databases of the statistical authorities or calculated by the author: absolute teacher salary and its growth, teacher salary as compared to the regional salary and ratio of teacher salary to the consumer basket of a working age adult. It is shown that during the period under review the living standards of teachers has been decreasing, and the target indicator has not been reached. The level of economic development of the region has a significant impact on the state of teachers. In financial centers, industrially developed or extracting of mineral resources regions, the standard of living of teachers is on average higher, while in less developed agricultural regions it is lower. Geographically, there may be presented two axes: the richer North and the poorer South and the richer Ural and eastern regions and the poorer western regions. Teacher salary reform does not reach its goal, which does not allow ensuring the continuity of teachers generations and negatively affects to the economy of Russia. To increase the standard of living of teachers, it is necessary to increase government funding, since under the low standards of living of the population of Russia the efforts of schools alone are not sufficient to reach this aim.

dc.description.abstract

value: This article discusses the main provisions of the Marxist theory of money in the context of modern trends in economic science. The problem of money in Marxism rarely became the subject of scientific research in the Soviet period of history, even less attention is paid to it now. This is probably due to the fact that Marx does not have a holistic concept of money, in his works you can find only disparate and often contradictory statements about what money is, what is their origin. For example, Marx rejected the quantitative theory of money, despite the fact that it is the basis of most monetary concepts. At the same time, in Marx’s works one can find many constructive hypotheses and theoretical findings that have enriched economic science. The theory of evolution of Marx value forms is an undoubted contribution to the development of the labor theory of value. Marxist understanding of money has played an important role in understanding how the mechanism of the capitalist economy works. The Marxist understanding of money was not devoid of flaws and contradictions, like any other scientific theory. The article deals in detail with the main provisions of the Marxist theory of value and the associated theory of money. It is also shown that Marx’s theory of cost was the result of his application of the dialectical method of research, which helped to avoid logical contradictions of the labor theory of cost inherent, for example, for the theoretical constructions of Ricardo. The paper deals with the contradictions characteristic of the Marxist theory of money.

dc.description.abstract

value: The paper proposes a bootstrap methodology for estimating cost efficiency in data envelopment analysis. We consider the conventional concept of Fare, Grosskopf and Lovellcost efficiency, for which our algorithm re-samples “naive” input-oriented efficiency scores, rescales original inputs to bring them to the frontier, and then re-estimates cost efficiency scores for the rescaled inputs. Next, we examine Tone cost efficiency, where input prices vary across producers. Here we show that the direct modification on bootstrap algorithms by Simar and Wilson are applicable. We consider cases both with the absence and presence of environmental variables (i.e. input variables not directly controlled by firms). The bootstrap methodology exploits these assumptions: 1) the sample are i.i.d. random variables with the continuous joint probability density function with support over production set; 2) the frontier is smooth; and 3) the probability of observing firms on the frontier approaches unity with an increase in sample. The results of simulations for a multi-input, multi-output Cobb–Douglas production function with correlated outputs, and correlated technical and cost efficiency, show consistency of our proposed algorithm, even for small samples. Finally, we offer real data estimates for the Japanese banking industry in 2013. Our package “rDEA,” developed in the R language, is available from the GitHub and CRAN repository.

dc.description.abstract

value: The purpose of this article is to investigate the history and content of scholarly studies devoted to the history of the medieval papacy at St. Petersburg University of pre-revolutionary times. The tasks of the article include both the study of historiographical sources, and a survey of disciplines related to the history of the medieval papacy taught at the Faculty of History and Philology of the University in 1819–1917. The author draws attention to the fact that this subject of educational courses and scholarly research for a long time remained “unpopular” among St. Petersburg medievalists. However, a real outline of university research in the field of “papal history” in historiography still hasn’t been done. The main way to identify the required courses of historical and ecclesiastical nature was to analyze university editions known as “The Announcements of Public Teaching of Sciences” and “Surveys of the Teaching of Sciences at the Imperial St. Petersburg / Petrograd University” and now accessible to a wide audience thanks to the portal “History St. Petersburg University in Virtual Space”. The author also refers to the materials collected during the biographical and prosopographical studies of the Center for History of St. Petersburg State University and concentrated in a number of network dictionaries (“The Network Biographical Dictionary of Professors and Teachers of St. Petersburg University” etc). On the basis of the data obtained, the author draws a conclusion about the extent to which the pre-revolutionary university research in the field of the history of the Holy See was developed and promising in reality.

dc.description.abstract

value: Evelopment of the several new synchrotron radiation sources has begun in Russia at the moment. The 4th generation Specialized Synchrotron Radiation Source SSRS-4 is the megascience project being developed at National Research Center “Kurchatov Institute”. The project is being realized in collaboration with the European synchrotron radiation source (European Synchrotron Radiation Facility, ESRF, Grenoble, France). It is assumed that theradiation source will include both storage synchrotron with energy near to 6 GeV and free electron laser. To achieve a design transverse emittance of 70-100 pm ⋅ rad it was proposed to use a multiple-band-achromat magnetic lattice. The length of the main storage ring will be about 1300 m, it will consist of 40 superperiods. Each period will include two antisymmetric magnetic arches and a free gap with length near about 5 m to accommodate embedded devices there between. It is proposed to use one linear accelerator with beam energy equal to6 GeV with two RF-guns: a photo gun for free electron laser and RF-gun with thermocathode for injection to the storage ring. Beam dynamics simulation results in such linear accelerator are discussed in this article.

dc.description.abstract

value: This article seeks to explain why, as the dissident movement burgeoned in the Soviet Union in the 1960s, there was almost no discussion about the October Revolution in samizdat, and it was the anti-Stalinist motif that predominated instead. It argues that at the time anti-Stalinism constituted a unifying language of activism for the “sixtiers” generation for several reasons: their communist upbringing; family ties to repressed communists; and the tacit acceptance of Khrushchev’s de-Stalinization as a reformist framework for their action. As they feared Stalin’s public rehabilitation, anti-Stalinism became the most pressing cause, pushing any deeper reflection on the regime’s legitimacy into the background. However, by the 1970s, as a result of increased repression and the growing isolation of dissidents, the movement had split into several currents. An avowedly non-political current, the human rights movement emerged as a result of the rejection of revolutionary violence. Renouncing the prospect of regime change, it staked instead on a “legalist” strategy, which precluded any questioning of the Revolution as the foundation of the current regime. By contrast, for the more politicized Russophile current represented by Aleksandr Solzhenitsyn, and for the democratic socialist current embodied by Roy Medvedev, it became important to affirm their vision of the Revolution and its place in history in order to affirm their own political programs. While Medvedev sought to offer a demythologized account of the October Revolution to bolster its legitimacy, Solzhenitsyn denounced the February Revolution as a fateful caesura in Russian history.

dc.description.abstract

value: Despite a large number of works devoted to the study of various aspects of Wipper’s life and his works, his biography still has not been researched comprehensively. In many respects this situation can be explained by the fact that there has never existed a tradition of passing down the knowledge about Wipper from his followers. There are two Wippers. The first is a left-wing intellectual with original views, who was not accepted by the community of Moscow historians. And the second is a post-revolutionary professor, who initially turned to the traditions of classical historiography, but then, thanks to the works on the history of early Christianity, turned toward Soviet historiography. As a historian, Wipper was very successful. Wipper’s pedagogical and scholarly career developed fast: the professor at the University in Odessa, one of three professors at Moscow University (since 1899), the leading professor of the university between the two revolutions. He met the revolution of 1917 without any obligations to the pre-revolutionary historians. At the same time, in the first years after the revolution, he selflessly began to defend the values of classical historical science. In this connection we can find a certain academic relationship between Wipper and the pre-revolutionary generation of historians. In this paper I will try to present Wipper against the background of the community of Moscow historians, with whom he had very uneasy relationships.

value: We describe a novel game-theoretic formulation of the optimal mobile agents’ placement problem which arises in the context of Mobile Ad-hoc Networks (MANETs). This problem is modelled as a sequential multistage game. The deﬁnitions of both the Nash equilibrium and cooperative solution are given. A modiﬁcation was proposed to ensure the existence of a Nash equilibrium. A modelling environment for the analysis of diﬀerent strategies of the players was developed in MATLAB. The programme generates various game situations and determines each player move by solving respective optimisation problems. Using the developed environment, two speciﬁc game scenarios were considered in detail. The proposed novel algorithm was implemented and tested using Network Simulator 3 (NS-3). The results show that the proposed novel algorithm increases network performance by using game theory principles and techniques.

dc.description.abstract

value: On the basis of the archival sources and memoirs of the contemporaries, the authors of the article reconstruct the university career of an outstanding Russian Slavic scholar V. I. Lamansky (1833–1914): from the period when he served as an officer in the administration of St. Petersburg Governorate to the time when he made a decision to resign from the university in protest against the government’s actions during the 1899 student unrest. It is noted that the foundations of Lamansky’s scholarly methodology was formed by Slavophile philosophy, since we can consider Lamansky the representative of the movement of so called academic Slavophilism. Lamansky’ orientation towards philosophical approach with regard to Slavic history and culture enabled him to become a founder of an independent historiographical school, with which a number of renowned Russian scholars can be associated. The authors underline that Lamansky realized himself more as a political thinker and philosopher of history than a researcher; however, this fact did not prevent him from contributing to Russian Slavic studies as an independent discipline with its own subject and method. Exploring Lamansky’s correspondence, the authors analyze Lamansky’s perception of 1884 University regulations and 1899 student unrest. It enables to demonstrate the specificity of Lamansky’s political views and some features of his personality. Therefore, contrary to the accepted viewpoint, prevalent in historiography since the Soviet period, according to which Lamansky was inclined to political conservatism and reactionary movement, we can argue that Lamansky’s political position was of liberal nature.

value: The article is a review of a new book by the Israeli historian Vera Kaplan, “Historians and Historical Societies in the Public Life of Imperial Russia”, which examines the participation of professional historians in the activities of various public organizations engaged in the formation and the popularization of historical knowledge in the Russian Empire. As a theoretical basis for her research, the author uses the concept of “public sphere” proposed by the modern German philosopher J. Habermas. This approach, which makes it possible to form a new view on the object of research, seems very productive. The author of the monograph reconstructs the activity of historical societies in the public sphere on the basis of a fairly representative source base. Beginning from the first decades of the 18th century, the author describes the process of forming communities of this type, focusing especially on the activities of public organizations of historical orientation of the second half of the 19th — early 20th centuries. These are, first of all, such organizations as the Imperial Russian Historical Society and the Society of Zealots of Russian Historical Enlightenment. The researcher analyzes in detail the process of the genesis of these societies, their ideological foundations, composition and structure, the main forms of their activity for studying the past and popularizing historical knowledge. At the same time, the article point out a number of polemical remarks concerning the aspects that remain beyond the attention of the author of the monograph under review.

dc.description.abstract

value: Since the First All-Union Congress of Soviet writers held in 1934, Socialist Realism had been officially considered the basis for Soviet literature and literary criticism. After the World War II its mission extended to the periphery of the Eastern bloc. Analyzing the aims of official propaganda through novels, one can consider the Soviet Union an “Empire by fiction”, to paraphrase Geir Lundestad’s fortunate title (who calls the United States an “Empire by Invitation”). To enhance unity inside the communist camp, writers often resorted to the perception of the enemy. Fearful and phantasmagorical, he is surrounded by an inspiring universe that unleashes the imagination of people. Then Yugoslav President Josip Tito became the case in question. “The Yugoslav Tragedy” (1951) came out three years after the Stalin-Tito split. Due to the acerbic condemnation of the “traitor” in the novel, together with a number of articles published in newspapers, Orest Maltsev, a stalwart of Socialist Realism, was awarded the Stalin Prize. Following Michel Foucault’s bi-functional nature of power, I argue that in Maltsev’s description of the Yugoslav enemy, not only does the Soviet regime punish guilty behavior, but it also legitimizes itself by enhancing Soviet prestige at war (the indisputable winner vs. the shameful resistance fighters) and so reinforces Soviet values. This paper offers a new perspective on those founding principles in the early Cold War era and explains how fiction was used as the main tool of imperial soft power.

dc.description.abstract

value: The fall of the Soviet Union prompted a vast amount of political change across the globe. A bipolar global power structure transformed into a unipolar diplomatic one. In the wake of this structural shift, the former Soviet Republics gained independence — along with all its merits and challenges. Great Powers were forced to reassess their relationships under new geopolitical conditions. Meanwhile, the newly formed Central Asian Republics were brought to the forefront of global attention. Kazakhstan, Kyrgyzstan, Turkmenistan, Uzbekistan, and Tajikistan’s developmental journey is not simply regionally significant, but also globally. Geographical, economic, and political factors make the region pivotal for the Great Powers. Faced with challenges like ethnic, religious, and political conflict; the Great Powers have competed to gain influence in the region. This competition has included both soft and hard power tactics. The scope of this paper is limited to three involved Great Powers in the region: Russia, China, and the United States. Their relationships with the Central Asian states are unique. The diversity of their foreign policy goals, capabilities, and challenges toward Central Asia paint a complex mosaic of international relations. Nevertheless, this analysis will clearly illustrate that these Great Powers have more opportunity for cooperation than just conflict.

dc.description.abstract

value: Resilience is an increasingly popular concept used to explore how systems respond to various challenges. It has been actively used in International Relations. Here, resilience has been analyzed in predominantly postmodernist terms. Yet, I take resilience-thinking, as explored by one of its leading scholars, David Chandler, and show that it has some affinities with political realism, understood, contra stereotypes, as a complex tradition of political reflection. I also apply the insights gained to the recent overarching turn to resilience in the EU’s external action. The article demonstrates that the novel stress of resilience-thinking on the complexity of the contemporary world is very important, but that it is useful to contextualize it and relate it, if in part, to the age-old concerns of the realist tradition, and to identify similar strengths and problems in both approaches. Both resilience-thinking and realism have drawn our attention to the plural aspect of politics. However, they may face problems concerning elements of relativism, a claim to know the ‘reality’ best, the use of fixed categories, irresponsibility, and the reification of an understanding of reality as a permanent crisis. All these strengths and problems will likely play out in the EU’s external action and even its internal development.

dc.description.abstract

value: In a currently highly competitive international environment, US goals of consolidating and strengthening NATO as well as bringing its present mission in Afghanistan to successful termination gain in significance. The success of these processes enhances the reputation of the United States as a powerful international actor. I checked the hypothesis that facing sharp critique from the United States president for free riding in NATO, those members who fail to meet the target of 2 per cent of GDP in their defense expenditure would choose to increase significantly their contributions to the Alliance’s efforts in Afghanistan. I did not find enough convincing empirical data to prove it. The contributions of allies rather reflect their power potentials and ambitions they pursue by cooperating in NATO framework. US allies remain able to define the scale of their contribution to collective efforts in NATO framework despite the US pressure. Broadening of the Alliance’s purview after the end of the Cold war provided member states with additional alternatives for choosing types of their involvement. My findings generally support the established view on intra-alliance bargaining process in scholarly literature. A wide range of missions in NATO framework and beyond it facilitates coalition formation for the United States with their numerous allies and partners. At the same time, if more major allies further choose to cooperate with Washington outside NATO, it will undermine its effectiveness and global role.

dc.description.abstract

value: When processing large arrays of empirical data or large-scale data, cluster analysis remains one of the primary methods of preliminary typology, which makes it necessary to obtain formal rules for calculating the number of clusters. The most common method for determining the preferred number of clusters is the visual analysis of dendrograms, but this approach is purely heuristic. The number of clusters and the end moment of the clustering algorithm depend on each other. Cluster analysis of data from n-dimensional Euclidean space using the “single linkage” method can consider as a discrete random process. Sequences of “minimum distances” deﬁne the trajectories of this process. The “approximation-estimating test” allows us to establish the Markov moment when the growth rate of such a sequence changes from linear to parabolic, which, in turn, may be a sign of the completion of the agglomerative clustering process. The calculation of the number of clusters is the critical problem in many cases of the automatic typology of empirical data. For example, in medicine with cytometric analysis of blood, automated analysis of texts and in other instances when the number of clusters not known in advance.

dc.description.abstract

value: Scientific research — in particular, military and nuclear — had proven during the Second World War to have the potential to demonstrate the superiority of a country. Then, its internationalization in the post-war period led to its being considered a key element of cultural diplomacy. In 1968, during the organization of a conference on general relativity and gravitation in Tbilisi, geopolitics and science encountered abruptly. As a consequence of the Third Arab-Israeli War between Israel and the neighboring states of Egypt, Jordan, and Syria in June 1967, diplomatic relations between the USSR and Israel were interrupted. Then, Israeli physicists initially were not invited to join their colleagues in Georgia. Such a political decision provoked a tense crisis that afterwards would affect the institutional organization of the scientific community dealing with the theory of relativity. The present article proposes to examine this episode of the history of science as part of the history of Soviet cultural diplomacy. Indeed, focusing on Soviet actors of the Israeli crisis in 1968, it is possible to better understand the political influences on scientists in the USSR. In this context, of particular interest is the international trajectory of the Head of the local organizing committee of the Tbilisi conference, Vladimir A. Fock. From his example, it is shown in the article that Soviet scientists primarily acted as representatives at the international level and were restricted in their movement. Their actions were under control of their scientific and political authorities.

dc.description.abstract

value: In nearly 30 years since the collapse of the Soviet Union, China and the five Central Asian countries have formed a strategic partnership of equal trust and mutual benefit. China’s interests in Central Asia focus on maintaining security in border areas, combating terrorism and extremism, gaining access to stable energy supplies, and expanding overseas markets and investment returns. In the course of its communication with the Central Asian countries, China claims its deep commitment to such principles as peaceful coexistence of all nations, non-use of pressure, military force or threats, mutual respect, refraining from establishing a sphere of influence and promotion of regional peace and development. The main policy tools for China to pursue its grand strategy in Central Asia include properly handling border issues, eliminating potential conflicts, developing good-neighborly and friendly relations with Central Asian countries. In order to achieve mutual benefit and win-win situation, China will continuously upgrade the level of strategic partnership, actively develop economic cooperation and energy cooperation with Central Asian countries. In addition, China will develop comprehensive cooperation with Central Asian countries through the Shanghai Cooperation Organization, balancing the interrelationships with Russia, the United States and other international actors (including some intergovernmental organizations) in Central Asia.

dc.description.abstract

value: The Arctic region has spectacular roots in Indian civilizational thinking and thus represents a familiar region. Shaped by its long association and significant expertise in the Antarctic Treaty System; its first scientific expedition to the Arctic Ocean in 2007 followed by the setting of the Arctic research base in 2008 and subsequently its Permanent Observer status in 2013, India’s dominant narrative remains scientific and polar research. But with summer in the Arctic arriving early and staying longer, accessibility to the vast natural resources and huge investment has significantly altered the geopolitical landscape of the Arctic region. The question of how to develop the resources in a sustainable and peaceful manner competes with the complex science of the Arctic and the unique risks that such commercial ventures pose. India’s reluctance to de-emphasize its scientific interest towards a more calibrated approach that takes into account the politico-strategic-economic dimensions in the Arctic reflects the tension between the exceptionalism and the realism of its polar legacy. The article assesses how the Arctic orientation is changing from a uni-dimensional to a dynamic and multidimensional engagement. The author argues that India’s Arctic approach is essentially binary: while indeed India has a stake in the governance of global commons and to cooperate with the littoral states for effective science policies, it also cares about sustainable resource development without making the Arctic region unstable.

dc.description.abstract

value: Lots of technical devices use ﬂows in pipes and channels caused by pressure drop, along with one’s axis, which is energy consuming and has to be estimated. For the estimation resistant coeﬃcient, dependent on ﬂow regime and streamlined surface roughness, is required. Turbulence f -model applicable for calculation for both laminar and turbulent ﬂow and smooth and rough walls is used for investigation. The problem of incompressible viscous liquid steady ﬂow in a smooth round pipe is considered for diﬀerent Reynolds numbers. First integrals for velocity proﬁle and turbulence measure are obtained in form of transcendental equations and solved by Newton’s method for algebraic equation system. Calculated results are compared with data from alternative theoretical approaches and experiments.

Control Processes, 2019, vol. 15, iss. 1, pp. 5–21.

dc.description.abstract

value: The stray poloidal magnetic ﬁeld produced in ITER outside the tokamak is signiﬁcantly higher than in any present machines. This magnetic ﬁeld magnetizes the steel rebar reinforcing the building concrete structures enclosing the tokamak. As a result, reinforced structures of the ITER building may produce a substantial magnetic ﬁeld with theaxisymmetric component (toroidal mode number n = 0) aﬀecting the plasma initiation and non-axisymmetric components (“error ﬁelds” with n = 1; 2) deteriorating plasma performance. This paper presents an upgraded Magnetic Model of the ITER Tokamak Complex,MMTC-2.2, for assessment of the stray ﬁeld associated with the reinforced structures. This magnetic model MMTC-2.2 takes into account the CATIA models of the Tokamak Complex Buildings and volumetric fractions of steel for the rebar in the building structures as they were in the design in 2016.

dc.description.abstract

value: We investigate weak solvability of the initial-boundary value problem for the hyperbolic equation with distributed parameters on the oriented limited graph and regional conditions of the third type. The spatial variable is changed to the limited oriented graph. The diﬀerential ratio was determined on the edges of the graph without the end points. Internal diﬀerential ratio graph nodes are replaced by generic terms of Kirchhoﬀ. The diﬀerential ratio in internal knots of the graph is replaced with the generalized conditions of Kirchhoﬀ (in applications the balance relations). The space of the admission weak solutions consists of functions with bearer on the graph belonging the space of Sobolev and satisfy the generalized conditions in “limits” sense. Idea analysis of initial-boundary value problem remains the classic: selected functional space with a special base (system of generalized eigenfunctions of an elliptic operator task), which consider the initial-boundary value problem; for approximations to the weak problem solving (the Faedo-Galerkin approximations) establishes a priori estimates of the energy type inequalities; shows weak compactness the Faedo-Galerkin approximation family. Previously initial-boundary value problem is seen in the space of functions with the second generalized derivatives and for such a task is proved equivalent energy inequality. From this it follows: a) convergence of Faedo-Galerkin approximation to the weak solution;b) approximation of the original problem of a course-measuring system of ordinary diﬀerential equations. In the work point out the path approximation of the original problem-dimensional system, which allows you to get the theorem on approximation used in the tasks of an applied character. Presents light conditions on the original task data, guaranteeing the weak solvability task. These conditions often occur in applications. Considered by the task and the approach to its analysis of enough is frequently often used in the mathematical description of the oscillation processes in technical designs-net, also in examining wave phenomena in hydronet. The results are fundamental in the study of problems of optimum (of optimum control)of network industrial construction.

dc.description.abstract

value: In this paper we considered analytically one of the key features describing the radiation from charged particles in periodic structures. It is shown that the dispersion relation in the radiation from periodic structures with a ﬁnite number of elements, both for polarization radiation mechanism and forbremsstrahlung-type mechanism, including those in undulators and wigglers, does not take into account all the details of the spectral-angular distribution. Based on the analysis of the asymptotic expression which allows one to represent the ratio of squares of sines as the sum of delta functions, the factor has been obtained that takes into account the contribution of additional peaks. The expression depends on the number of elements of the periodic structure, and in the limiting case of very large number of elements turns into well-known asymptotic expression. The resulting expression has been obtained in the form helpful for further mathematical analysis, including the use of saddle point technique.

The characteristic function is constructed, its supermodularity is proved for the case of a one-step subgame starting with the second stage. For a special class of networks (star-network), a simpliﬁed formula for the Shapley vector is found, which does not require the calculation of the values of the characteristic function over all coalitions, but only over coalitions of dimension no more than two.

dc.description.abstract

value: The game-theoretic model of data transmission in a network of a given topology is presented. Two players (network nodes) tend to send as many random data packagesas possible to the ﬁnal nodes through one common node. Each playerhas a ﬁnite capacity buﬀer for storing data packages. A system of costs for sending and storing data packages andrewards for the successful package delivery is introduced. A dynamic conﬂict-controlled process is modelled as a stochastic gamewith a ﬁnite set of states. The existence of the Nash equilibrium and a cooperative solution is proved. The cooperative solution is a strategy proﬁle which maximizes the total expected payoﬀ. The price of anarchy in the network is calculated. The price comparesthe players’ payoﬀs in the Nash equilibrium and cooperative solution.

dc.description.abstract

value: The scholarly heritage of the historian Robert Y. Vipper belongs to Russia and Latvia. Vipper is a brilliant connoisseur of ancient history, philosophy, law, religion, culture of the East, an experienced researcher of European and world history. In 1924 he emigrated to Latvia and became a professor at the University of Latvia. The historian was a follower of the spiritual heritage of the philosopher, jurist, historian Giambattista Vico, who at the beginning of the 18th century was the first in the history of European humanitarian knowledge to carefully consider local cultures, local history, social life, legal system, economy, the entire hierarchy of values (religion, art, language), to evaluate the contribution of local cultures to the universal culture. Professor Vipper was able to apply, theoretically and practically, the ideas of Vico to his works written in the emigration in Latvia. He paid paid special attention to the formation of the national historical science, to a comprehensive study of the peasant question in the history of Latvia. But one should also remember the contributions by Garlib Merkel, Yuri Samarin and his book “The Peasant Question in Livland” (Berlin, 1876) to the study of the peasant issues in the history of Latvia. The novelty of Vipper’s writings on the peasant question in Livland was concerned his thorough study of the legislative acts of the late 16th-early 18th centuries, which led to the enslavement of peasants. In his works in Latvian, German and Russian languages the scholar managed to introduce the history of Latvia and the history of the peasant question in Livland into the context of European history. Over the 17-year-period of his life in Latvia, Vipper had published many teaching aids for schools and scholarly works in Latvian on the history of modern times (XVI–XIX). The professor brought up a large number of Latvian historians, always urging students to study the archives in Riga.

dc.description.abstract

value: The article contains an attempt to reconstruct a collective portrait of the historians of the Saint-Petersburg University in the 18th — beginning 19th centuries. The basis of the study is a network database “Petersburg historical higher-school (18th — beginning 19th centuries), created in the frames of the cognominal collective research project. Biographical material, concerned with the activity of the scholars, that worked in different institutes or were related with the historiography of the Petersburg University corporation (Academic University and “academic all-training school”, Teachers’ seminary, Pedagogical Institute, Imperial Saint-Petersburg / Petrograd / University) are analyzed in the article. It demonstrates that the formation of the scholar schools in the historical discipline began in the 2nd quarter of the 19th century. The attention paid to different aspects of the collective portrait of the historians of the Saint-Petersburg University: estates origin, creed, academic mobility, education etc. However, mostly in concerns on the themes of the research, its’ evolution and on the process of historical scholar schools’ formation. It is featured that the historical studies united the representatives of three faculties of the Imperial University in the 19th — beginning of the 20th century (historical-philological, juridical and oriental languages) and took central positions among the researches. The authors demonstrate interaction, partially conjunction of the fields of study and close collaboration between historical, philological sciences and study of art. Particularly pointed out that the major University’s scholars founded scholar schools that had followers in different humanitarian studies. The article also stresses upon the interaction and interinfluence between Moscow and Petersburg historical scholar schools.

dc.description.abstract

value: The article is devoted to two anniversaries of St. Petersburg University — the 295th anniversary of the foundation (the decree of Emperor Peter the Great) and the 200th anniversary of the official renewal (the decree of Emperor Alexander I). The article focuses on the controversial path that a university corporation had taken from an “academic” university of the 18th century to the mass university of the early twentieth century. The article shows the unity of the tradition of university education in St. Petersburg, reconstructs the logic of transformations of university education institutions in the capital of the Russian Empire in the 18th — early 19th centuries. The inextricable link between the corporate history of the metropolitan university and the history of the development of the “university ideal” and “university model” in modern Europe is demonstrated. The work traces the main milestones of the institutional history of St. Petersburg University in the context of the socio-political history of Russia, changes in the nature of the state and public order with regard to university education. The paper discusses the main regulations governing the organization of the university (in particular, the Regulations on the Establishment of the Academy of Sciences and Arts in 1724, Regulations and States of the Academy of Sciences and Arts in 1747, University Charters of 1804, 1835, 1863, 1884, and etc.). Particular attention is paid to the concept of “university autonomy”, its role in the life of the university. The role of the St. Petersburg (Petrograd) University in the social and political life of Russia before the revolution is considered.

dc.description.abstract

value: The ecological concept of resilience means the ability of the system to adapt aftershocks. During recent decades, it has been transferred to the social sciences, including the theory of international relations. At the same time, studies of the crisis resilient subject are characterized by an excessive focus on the grassroots civil society initiatives and stigmatization of the governmental component. Building upon the ideas of German political philosopher C. Schmitt, the author proposes an alternative conceptualization of the emergence of a resilient subject. This model includes the sovereign’s Decision, new social normality after the Decision and the public response to it as the key parts. The comparative analysis of news reports is a methodological basis of this research with two natural disasters (Hurricane Katrina in New Orleans 2005 and the Haiti earthquake of 2010) and two series of terrorist attacks (in Barcelona and the United Kingdom in 2017) being the case studies. Special attention to the role of critical infrastructure and fluctuations of public order makes it possible to describe the central place of the governmental component inside the emerging resilient subject. Moreover, a high degree of state capacity in the field of technocratic administration cannot guarantee the emergence of the resilient subject during the crisis. It is impossible to cope with the system challenges without the effective interaction between state and society.

New trends in the study of scholastic problems in recent years, including the anthropological approach (interest in personal relationships within schools, not only within the dichotomy of “teacher-students”, “intraschool” conflicts, etc.) are characterized. Taking new approaches into account, the origin, school structure, genetic interrelations between different parts of the general Kievan school are examined. Students of the founder of the school N. D.

V. Golubovsky, A. S. and M. S. Grushevskies, V. E. Danilevich, M. V. Dovnar-Zapolsky, V. G. Lyaskoronsky, N. V. Molchanovsky) and Vladimirsky-Budanov (G. V. Demchenko, N. A. Maksimeyko, I. A. Malinovsky, A. Ya. Shpakov, M. N. Yasinsky) comprised the second generation of Kievan school. Vladimirsky-Budanov and his disciples, in addition to Leontovich and his student F. V. Taranovsky, shaped a special school of Western-Russian law in Russian historiography. Finally, the third generation of Kievan school was comprised by the students of M. V. Dovnar-Zapolsky (A. M. Gnevushev, F. Ya. Klimenko, B. G. Kurts, P. P. Smirnov, E. D. Stashevsky, N. F. Yanitsky and others). Their active scholarly work coincided with the 1910s — 1920s. The article explores ideological origins and organizational reasons for the emergence of the school. Similarities and differences between the schools of Dovnar-Zapolsky and Antonovich, deriving from each other, are shown. The article concludes that the school existed within the framework of a single all-Russian historiography.

dc.description.abstract

value: The article is devoted to the analysis of memoirs and documents from the personal archive of B. Souvarine, one of the founders of the French Communist Party, historian, French Sovietologist, known little in our country. In the early 1920’s, Souvarine worked in the Third International in Moscow and was forced to leave for the West because of his bluntly critical attitude to the Stalin’s methods of building socialism. Being an eyewitness of the early years of the Russian revolution and an astute observer of post-revolutionary events, he left vivid testimonies of Soviet history during the interwar twenties. Personal acquaintance with Soviet writers — Gorky, Babel, Pilnyak, Zamyatin, Pasternak, Ehrenburg — allowed him to soundly write about the problem of “writer and power” and the writers’ situation in the USSR in his essays of both retrospective and actual type that he published in “Preuves” magazine during the period of the Cold War. Honest and insightful analysis by Souvarine significantly widened the boundaries of awareness of the Western reader about Soviet literature. Unlike many Western Sovietologists, Souvarine was able to distinguish between the ruling power and people strangled by it. By criticizing the regime and all the horrors associated with it, he was able to tell the Western reader about the literary life hidden behind the raids of officialdom; this way he served as a mediator in the intercultural communication of his time.

dc.description.abstract

value: The category of resilience has long since become an actively used term in social sciences. However, more and more actors of international relations, both states and international organizations, have recently been striving to include “resilience” into their agenda and to attach it a conceptual and, what is true in the case of the European Union, even a normative content. Therefore, there emerges a global trend that “resilience” is gradually becoming an important category of foreign policy. This article analyzes the usage of the category of resilience in the official discourse of the People’s Republic of China. At the beginning, we consider how “resilience” was used in the Western academic discussion to describe and explain political processes in China and how that discussion correlates with the current understanding of resilience as an instrument of foreign policy. In this regard, the European Union Global Strategy serves as a starting point in which the category of resilience for the first time has acquired a normative dimension. Then we refer to the examples of using the concept of resilience in the Chinese language and, first, define by means of which words this concept was incorporated into the Chinese discourse; second, we point out some variants of translation of “resilience” being used in the official discourse of the People’s Republic of China; and third, we point out whether this concept assumes any novel normative content in China as compared with the resilience concept set out in the European Union Global Strategy.

dc.description.abstract

value: The inﬂuence of the molecular vibrational state on the rotational energy relaxation time is studied in the state-to-state approach. The rotational levels of the molecules are described by the nonrigid rotator model; their interaction is described by the variable soft sphere model. According to this model, collision cross sections for N2-N, O2 -O, NO-O interactions are calculated for diﬀerent vibrational and rotational levels of molecules. On the basisof the kinetic theory of nonequilibrium processes, the rotational relaxation time is introduced for each vibrational level. Relaxation times are calculated numerically in the wide temperature range, and a comparison with the relaxation time obtained by the well-known Parker formula is carried out. The inﬂuence of various multiquantum rotational transitions on the accuracy of the calculation of the rotational relaxation time is analyzed; the convergence of the solution is shown with increasing the maximum possible number of quanta transferred during the transition. It is shown that the vibrational state of the molecule signiﬁcantly aﬀects the rotational energy relaxation time in the state-to-state approach; when calculating the state-speciﬁc transport coeﬃcients, the use of the Parker formula can lead to a noticeable error. In the one-temperature approximation for moderate temperatures, the Parker formula provides a satisfactory agreement with the results obtained by averaging the state-resolved relaxation times with the Boltzmann distribution over vibrational energy.

dc.description.abstract

value: The paradox of innovation as the problem to be innovative while also gaining legitimacy is the underlying idea of this paper. How are innovative entrepreneurs and their ideas affected by the need to find the legitimacy of their audience to have customers? Through qualitative interviews, this paper discusses the importance and influence of legitimacy for innovative entrepreneurship. This paper investigates the importance of legitimacy processes for entrepreneurs and points out enhancing, as well as, impeding factors that legitimacy gathering process have on innovations. It finds understanding as the main source affecting legitimacy processes and shows the different strategies for entrepreneurs to gather legitimacy. Furthermore, the work provides insight about the context-specific elements of the legitimacy gathering processes, as well as, an illustration and differentiation of the audience as the second group involved in legitimacy processes. This paper provides a new framework that discusses legitimation processes as an interplay between the entrepreneur and individuals of the audience. This new framework is an attempt to solve the long-lasting debate concerning the locus of control in legitimacy processes between institutional and cultural entrepreneurial scholars, by placing the locus of control in between a circle of influence and a circle of understanding.

dc.description.abstract

value: Method of consecutive projections (MCP) is quite popular. The principal idea of the method is to present the convex set as intersection of simple elementary convex sets and project to sets, outer for the current point. To build projection onto elementary sets very easy, because elementary sets are semispaces. It was proved, that this algorithm is ﬁnitely convergent. Each iteration of MCP has 3 tasks: 1. choose elementary set for projection; 2. deﬁne direction; 3. calculate length of step. Typical features of the method for deconvolution problems are the large dimension and the presence of a large number of almost perpendicular directions of projection. We found that several sequential steps in perpendicular directions can be replaced by one step, indicating a simple way to build it. Although the theoretical speed of convergence of the method remained the same, for large-scale problems (of the order of hundreds of millions), characteristic, for example, for image processing, it was possible to reduce the counting time by hundreds of times.

value: The paper is devoted to the problem of constructing robust Т-optimal discriminating experimental designs for two competing trigonometric regression models, which diﬀer by at most three trigonometric functions. To solve this problem we propose to use a Bayesian and standardized maximin approaches. In a number of special cases the robust T-optimal discriminating designs were found explicitly. In general case because of the complexity of the optimization problem, the corresponding optimal designs are not easy to ﬁnd and have to be determined numerically. The results are illustrated in several examples.

dc.description.abstract

value: The inﬂuence of the relative thickness of the “stiﬀ” viscoelastic layer polymer and the orientation of the reinforcing layers of the power layer on the values of their natural frequencies and loss factors of damped oscillations unsupported two-layered composite plate is investigated. It has been established that each natural vibration mode of two-layered plate corresponds to a certain eﬀective relative thickness of isotropic viscoelastic polymer layer. Further increase in relative thickness for plates with orthotropic or transversally isotropic bearing layer depending on ambient temperature may result in both growth and decrease of natural frequencies without any considerable change of their energy dissipation. For the plates with monoclinic bearing layer, increase in relative thickness of isotropic viscoelastic polymer layer is accompanied by both decrease and increase of loss factor for diﬀerent vibration modes because these structure have membrane-bending-shearing interaction that results in the change of natural vibration shapes. It is shown that change in stacking sequence of reinforcing layers in the bearing layer with respect to global axes of two-layered plate brings about mutual transformation domains of coupled vibration modes. It has been established that mutual transformation of natural coupled vibration mode shapes of unsupported quasi-uniform rectangular plate appears in case if at least in one of the plate directions one of the natural shapes has an even number of quarter-wavelengths, whereas another natural shape has odd. It has been demonstrated that temperature-frequency relationship of elastic-dissipative characteristics of the “stiﬀ” viscoelastic polymer has a considerable eﬀect upon natural frequencies and loss factors of all the investigated vibration modes for unsupported rectangular two-layered plate.

Representations, in which such record values are equal in distribution to sums and products of independent and identically distributed auxiliary random variables, are provided in the paper. By these representations distributional and moment characteristics of lower and upper record values taken from uniform samples are studied. Sequential sums of lower record values which are taken from samples of independent and uniformly distributed random variables are also discussed in this work. The distributions and the Laplace transforms of the given sums are studied. The Laplace transform of the series of lower uniform record values are found. In the present work, we also compare the sums of lower order statistics and record values which belong to a certain uniform sample.

dc.description.abstract

value: We consider a diﬀeomorphism of a plane into itself with a ﬁxed hyperbolic point at the origin and a non-transversal homoclinic point to it. Periodic points lying in a suﬃciently small neighborhood of the homoclinic point are divided into single-pass and multi-pass, depending on the location of the orbit of the periodic point with respect to the orbit of the homoclinic point. From the works of S. Newhouse, L. P. Shil’nikov, B. F. Ivanov and a number of other authors it follows that for a certain method of tangency of the stable and unstable manifold an arbitrarily small neighborhood of the nontransversal homoclinic point can contain an inﬁnite set of stable periodic points, but at least one of the characteristic exponents of these points tends to zero with increasing period. From the previous works of the author it follows that for the other method of tangency of the stable and unstable manifold, an arbitrarily small neighborhood of the nontransversal homoclinic point can contain an inﬁnite set of stable single-pass periodic points. Characteristic exponents of these points are separated from zero. In this paper it is shown that under certain conditions imposed, ﬁrst of all, on the method of tangency of the stable and unstable manifold, an arbitrarily small neighborhood of the nontransversal homoclinic point can contain a countable set of multi-pass (exactly two-pass) stable periodic points. Characteristic exponents of these points are separated from zero.

value: Traditionally, non-linear wave propagation has been under consideration in classical hydro-dynamics, as well as in such areas of physics like optics and plasma theory. By contrast, we study the same problem within the framework of deformable solid body theory. Speciﬁcally, non-linear wave propagation is considered in a basic model of pipeline. We make use of classical non-linear thin elastic shell equilibrium equations along with Euler equations for a non-compressible non-viscous liquid. A soliton-type asymptotic solution is constructed. The existence of the single soliton on the “dry” shell is proved; while on the “ﬁlled up” shell there exist exactly two solitons. The behavior of these solutions was studied under the inter-connectedness factor, numerical results are provided. The results obtained may be put in practice, like construction engineering.

It is devoted to the works on characterization of distributions and various limit theorems in Statistics including asymptotic eﬃciency of tests, criteria based on characterizations and normal approximation for L1 -norms of kernel density estimators. The characterization results are related to independence and equidistribution of linear and non-linear forms of the sample as well as to regression relations, admissibility and optimality of statistical estimators. When calculating the Bahadur eﬃciency, we give attention to the logarithmic asymptotics for large deviations of test statistics under the hypothesis. We study also the conditions of local asymptotic optimality in Bahadur sense for various nonparametric tests.

dc.description.abstract

value: In the work we construct so-called convergence rings for the ring of integers of a multidi-mensional local ﬁeld. The convergence ring is a sub-ring of the ring of integers having the property that any power series with coeﬃcients from the sub-ring converges when replacing a variable on an arbitrary element of the maximum ideal. The properties of convergence rings and an explicit formula for their construction are derived. Note that the multidi-mensional case is fundamentally diﬀerent from the case of the classical (one-dimensional) local ﬁeld, where the convergence ring is the whole ring of integers. Next, we consider a multidimensional local ﬁeld with zero characteristic of the penultimate residue ﬁeld. For each convergence ring of such a ﬁeld, we introduce a homomorphism that allows for a power series with coeﬃcients from the ring to construct a formal group over the same ring with a logarithm having coeﬃcients from the ﬁeld, and we give an explicit formula for the coeﬃcients. In addition, we constructe a generalization of the formal Lubin-Tate group over this ring, study the endomorphisms of these formal groups and derive a criterion for their isomorphism. We prove a one-to-one correspondence between formal groups created by ring homomorphism and by isogeny. Also for any ﬁnite extension of a multidimensional local ﬁeld with zero characteristic of the penultimate residue ﬁeld, we considere the point group generated by the corresponding Lubin-Tate formal group.

dc.description.abstract

value: Theory of the ﬁgures of celestial bodies, which are in the state of hydrostatic equilibrium under gravitational, centrifugal, and pressure forces, took the form of a rigorous mathematical theory in the second part of the XX century. Fundamental physical laws served as its basis. The Huygens-Roche ﬁgure (total mass is concentrated in the centre, while the rotating atmosphere takes the equilibrium form) plays an important role in the theory. Properties of the ﬁgure are carefully examined. In particular, it is known that each isobar (surface of equal pressure) represents one of the three-parameter family of the Huygens- Roche surfaces. Meanwhile, convexity (or its absence) was not dicussed in the literature as far as we know. It is worth noting that there are non-convex ﬁgures between equilibrium ones. In the present paper, we ﬁnd the curvature of a meridional section of an arbitrary Huygens-Roche ﬁgure (in the closed form as well as in the form of a series in powers of the Clairaut parameter, main in the theory of equilibrium ﬁgures). We succeed to prove that the curvature is positive and is separated from zero. Hence, each surface from the Huygens-Roche ﬁgures family is convex, and has no points of ﬂattening. Moreover, no curve on its surface has points of straightening.

dc.description.abstract

value: In a linear approximation a deformation of a thin elastic anisotropic heterogeneous in the thickness direction plate is investigated. By using an asymptotic solution of 3D equations of the theory of elasticity, a 2D model of the second order accuracy with respect to the small thickness parameter is built for a plate with the general anisotropy that is described by 21 elastic modules. The obtained system of equations describes deﬂections of a middle layer and has the diﬀerential order, coinciding with the order of the Timoshenko-Reissner model. The model is acceptable to an investigation of statics, dynamics and stability of multi-layered, and also functionally graded plates. In the previous works, the models of the second-order accuracy were constructed for isotropic plates and for plates with partial kinds of anisotropy. The general anisotropy is studied ﬁrst.
