POTENTIAL ENERGY IS A CATEGORY OF SPACE
Authors:   Transbaikal State University, Chita, Pavlenko Yu.
Published: April 2022

A theoretical model of potential energy is presented as a world space filled with “dormant” energy waves of low oscillation frequency, diverse in configuration. It has been established that the interaction of locally manifested wave processes of quantum fluctuations, interference and diffraction in areas of increased energy concentration upon reaching the anomalous threshold oscillation frequency of 734 Hz forms elementary particles with a denser mass, increased energy charge and other characteristics characteristic of baryonic matter. The relevance of the research is observed in the expediency of systematics, structuring fundamental knowledge about matter, its “sources” to clarify the methodological principles and the significance of the evolution of “original” energy in natural science. The object of the research is potential energy, which is one of the most important methodological categories in the form of space. The subject of the research is the fundamental properties of potential energy, which ensure the existence and evolution of the matter of the Metagalaxy. The purpose of the study is virtual forms of the existence and evolution of energy, and the main task to be solved is to clarify the significance of the wave quantum fluctuation of energy. The methodological tool for solving the problem is the numerous fundamental structural levels of the organization of the matter of the Universe, indicating its polygenic energy essence and evolutionary nature. The concept of a system of scientifically based, interconnected and logically linked scientific views based on many years of experience in small-medium-scale predictive studies in the oldest mining region of Russia - Eastern Transbaikalia. Encyclopedic natural-science knowledge of the matter of the Universe, fundamental hierarchical structures of its matter, cause-and-effect relationships of the functioning of energy systems, theoretical and practical models of the Earth's matter, as well as knowledge of the objective perception of the world, its laws and phenomena by collecting, computer processing of empirical data to solve the problem are used. . It is taken into account that dialectical materialism beyond the “visibility” (length) of light (optical) and electron waves is gradually being replaced by theoretical (philosophical) materialism based on the laws of logic and fractal. Physically invisible all-penetrating potential energy is consumed by all material particles, all inorganic and organic bodies, without this “spatially nourishing” energy, physical existence is excluded.
ON THE ISSUE OF NATURE MANAGEMENT IN MOUNTAIN COUNTRIES (GLOBAL AND REGIONAL ASPECT)
Authors:   Transbaikal State University, Chita, Russia, Tomskikh А.
Published: April 2022

Mountains and man form an important global geo-economic system, on which the sustainable development of the entire world civilization depends and it brings the problem into the category of extremely urgent. Scientific and management events devoted to various issues of the state and development of mountain territories began to be held in Russia since the 1990s: the issue “Rational use of vulnerable ecosystems: sustainable mountain de- velopment”was discussed at the UN Conference on Environment and Development of Agenda for the XXI century. A significant reserve in this regard has been formed since that time in our country, in a region where mountains occupy about half of the territory. The object of the research are mountainous areas. The subject of the research are principles of nature management organization in mountains. The purpose of the research is to reveal specificity of nature management in the mountain countries for development of systems of nature management. In mountain areas, along with fundamental scientific research, the results of the work are being implemented into practice and management with varying success. The article indicates the need for further increasing scientific research on the problems of sustainable development of mountain territories and their special type of natural and economic environment-intermountain basins. This requires long-term and multifactorial research; scientists should be ready to cooperate in interdisciplinary questions; managers of different levels should be able to rationally apply scientific results. As applied aspects, the paper considers approaches to nature management on the example of Altai, Transbaikalia and the Caucasus. The experience of similar studies of mountain countries in Europe and the CIS is considered. Here the mountains occupy a significant territory and the problems of the relationship between man and the environment are connected with them. The task is to continue the research of the natural and economic specifics of the depressions of the region in the experience of the basin concept in nature management, their zoning, structural and functional modeling

Russia's “turn” to the East, due to the high practical significance of the problem, is one of the most discussed in the Russian political discourse of the last decade. Over time, the positions of researchers change from passive-pessimistic based on a variety of problems in this area, to more positive, and based on certain achievements. To date, it seems timely to summarize the interim results. In the article, the authors summarize the ten-year path of Russia's “eastern choice”. They compare the initial plans and statements of the political leadership with the concrete results achieved over ten years of work, which was largely carried out by trial and error. The authors conclude that the loud slogans were largely political PR, designed to attract the attention of the international community and its citizens, in order to successfully launch the program. However, there was no breakthrough “turn” of Russia to the East. These were the first steps that brought certain indicators both in concrete figures and intangible assets - a positive view of Russia from real and potential Asian partners. The object of the study is the policy of “turning” Russia to the East. The subject is the socio-economic results of the policy of “turning” Russia to the East for the Far Eastern region. The purpose of the study is to identify the socio-economic results of the development of the Far Eastern region, determined by the “turn” of Russia to the East, to identify new challenges and opportunities for its rise. Research methodology. The authors' research concept is that a region is not an exclusively autonomous, but a multifunctional composite organism developing both on the basis of vertical (center-region) and horizontal (interregional, intraregional) interactions included in the system of intra-state and world economic relations. Methods of retrospective, comparative and historical analysis were used to determine the level and dynamics of socio-economic development of the region

The Asian vector of Russia's policy has necessitated the development of various spheres of the economy of the Far East, one of which is tourism. Tourism in the modern world is a promising profitable industry, which is relied on by both highly developed and developing countries. Favorable factors of tourism in the Far Eastern territory have determined the importance of this direction, assigning it the mission of the locomotive of the economy of the Far Eastern Federal District. The success in this area largely depends on the economic development of the region, improving the welfare of the population, an attractive image of the territory, as well as the well-being of Russia as a whole. The authors investigate the current state of the tourism industry in the Far East. The analysis of current trends in its development is carried out. Identify problematic issues that require their solution. So, among the weaknesses of the industry, the authors name the negative image of Russia in the world, anti-Russian sanctions, difficult climatic conditions, high cost and distance of flights, insufficiently developed infrastructure of the territory, etc. They give an optimistic forecast to the prospects for the development of foreign tourism, based on the fact that many large investment projects are being implemented in the Far Eastern region, the territory has a great potential for natural and recreational resources, there is a neighborhood with Asian states with a high population, etc. The object of the study is tourism in the Far East. The subject of the study is the current state and prospects for the development of foreign tourism in the Far Eastern Federal District. The purpose of the study is to identify the strengths and weaknesses of the tourism industry in the Far East, to make a forecast of its development. Research methodology. As a methodological basis, an interdisciplinary approach is used in the work, which allows a comprehensive study of the economic, social and cultural aspects of foreign tourism in the Russian Far East. General scientific methods are used - analysis, synthesis, induction, deduction, analogy, etc., which make it possible to identify not only the factual side of the problem - the development of the tourism industry in the Far East, but also to trace its development in dynamics and make a forecast for the future. The method of comparative analysis made it possible to identify the advantages and disadvantages of the resource component of the modern tourism business in the region. The complex use of these and other methods allows us to recreate an objective and dynamic picture of the subject of research

Published: April 2022

The article is devoted to the current state of the problems of reforming local self-government and the direct relationship of political parties to the reform of local self-government in Russia. The subject of the article is the aspects of reforming local self-government in the vision of political parties. The purpose of the article is to study the essence of municipal reform in the party discourse devoted to the problems of constitutional reform of local government at the present stage of development of Russia. This article presents various methods, such as analysis, comparative method, which to a greater extent make it possible to define the conceptual apparatus, to conduct a comprehensive analysis of the current state of local self-government in Russia in the context of municipal reform. The reform of local self-government initiated in 2019 affected the essential constitutional foundations of local government that have existed since the adoption of the Constitution of Russia in 1993. In the new constitutional and legal realities, a qualitatively new model of local self-government in our country has been fixed: the place of local government in the vertical of state power, the territorial basis of local self-government, the structure of local self-government bodies and the procedure for institutionalization of local self-government bodies and officials has changed. The attitude of representatives of political parties to this municipal reform is quite polar, party members do not unequivocally assess the consequences of the reform of local government. The results of the study can be useful in conducting seminars for municipal employees and heads of municipalities, and the results of the article can also be applied in the work of members of political parties and their regional branches, whose members are members of legislative (representative) bodies of Russia and its subjects, in the course of legislative activity

T he article is devoted to identifying patterns of transformation of interaction between the state and confessions in pre-Soviet Russia. The object of the research is the state approach to state-confessional relations. The subject of the research is the influence of liberalism's ideas on religious reform in Russia and the Soviet Union. The purpose of the research is to examine the conceptual and practical aspects of religious reform in Russia and the Soviet Union. The authors have revealed that the interaction between state and confessional spheres during this period has developed according to the direction of reformatory activity of rulers, who sought to bring the religious sphere under a single principle, embodied in the formation of the church concept of power. The novelty of the research is associated with the justification of the existence of two trends influencing the confessional policy of the state, one of which is associated with the desire to achieve a greater degree of religious freedom. The other is related to the desire to preserve order, which is realized in a number of restrictive measures in relation to other religions and protectionist measures in relation to Orthodoxy. The article proves that in the early twentieth century these processes are significantly transformed, being influenced by the reforms, the implementation of which eventually led to the beginning of the era of liberalization, which legislated the norms of natural law and constitutional order

The relevance of the research topic is due, first of all, to the implementation of an important strategic task - ensuring the stability of the economic development of the countries of the world in the face of uncertainty and the socio-economic consequences of the pandemic crisis. Under these conditions, it is necessary to study the features of the digital transformation process development in the agri-food sector and assess its impact on the food market. Ensuring global strategic stability is a paramount task for the modern development of many countries. The development of the global digital transformation of the Russian economy in the context of fierce hypercompetition involves the creation of new adaptive mechanisms for the interaction of economic entities and institutions, taking into account the current unstable epidemiological situation in the country and in the world within a single information space. Global instability caused by the uncertainty of economic development requires the development of constructive strategic solutions aimed at stabilization. The development of the digitalization process covers many types and areas of activity and requires additional support and attraction of foreign investment. The food market is one of the important elements of the food supply system for the population with basic foodstuffs. In the context of the development of the digital transformation process, it is necessary to study the influence of a number of factors on the development of the food market. In particular, the state of the market situation, the level of effective demand of the population for the development of the food market in the regions of the Far Eastern District. The development of the digital transformation process has an inadequate impact on the development of the food supply system. This is due not only to the introduction of modern innovative technologies, the creation of new digital ecosystems. Digitalization involves minimizing human participation in the implementation of economic processes based on the use of modern digital technologies is quite remote. In a pandemic crisis, the digital transformation process development becomes a necessary condition for the functioning of business structures in the agri-food sector. Social paratroopers, remote work, training have capitalized on the trend towards the merging of digital and physical reality. Digital channels and services have enabled consumers to get a wider range of services, in particular, in 2021, e-commerce grew by 25 %, online food delivery by 27 %

Published: April 2022

The demand for liquid carriers, such as liquefied natural gas (LNG), has increased in recent years. One of the most common types of LNG carriers is the membrane type, which is often built by a shipyard with a prismatic tank shape. This carrier is commonly known for its effective ways to mitigate sloshing using a baffle. Therefore, this study was performed to evaluate sloshing in a prismatic tank using vertical and T-shape baffles. The sloshing was conducted with 25% and 50% filling ratios because it deals with the nonlinear free-surface flow. Furthermore, the smoothed particle hydrodynamics (SPH) was used to overcome sloshing with ratio of a baffle and water depth is 0.9. A comparison was made for the dynamic pressure with the experiment. The results show that SPH has an acceptable accuracy for dynamic and hydrostatic pressures. Baffle installation significantly decreases the wave height, dynamic pressure and hydrodynamic force.

Published: April 2022

Although many studies have focused on consumer behavior, a summary of constructs specialized in switching behavior is unexplored. The research aimed to enlarge an extensive and updated overview of customer switching behavior in the service industry. The Systematic Literature Review (SLR) technique evaluated 35 scientific papers released from 2011 to 2021 to analyze drivers, mediating factors, moderating factors, and outcomes related to customer switching behavior. The results improve the understanding and outcome of the drivers to retain consumers. First, the drivers (independent variables) consist of social factors, firm factors, customer behavior, and cost. Second, mediating factors include switching cost, experiential psychological states, inertia, emotion, and consumer perception. Third, moderating constructs have mooring factors, satisfaction, and inertia. Surprisingly, inertia appears in both mediating and moderating variables. The difference depends on service context. Last, outcomes consist of customers’ responses, low satisfaction, and low loyalty. The research contributes to theoretical and managerial implications for sustainable planning by making an overview of several service models. In addition, it includes the drivers of switching behavior in the service industry. Furthermore, the framework offers possibilities and issues for future research and moves the focus from the conventional service domain to social networking that refers to the online platform.

Published: April 2022

The importance of retailers to utilize interactive technology, such as Augmented Reality (AR), in their mobile applications is considered due to the change in consumer behavior from in-store to online. However, there is limited study in understanding consumer perception to evaluate the effectiveness of AR implemented by retailers during the COVID-19 pandemic in developing countries like Indonesia. The research examined the relationship between AR characteristics, consumer perception, and attitude toward AR in mobile furniture retail applications. The intention to adopt was also included in measuring behavioral responses. Using 383 valid data, the researchers empirically tested the insights through Partial Least Square-Structural Equation Modelling (PLS-SEM). The results reveal that AR characteristics have a significant influence on consumer perception. Besides, perceived functional benefit and trust in AR directly relate to attitude toward AR and indirect on intention to adopt AR applications. Thus, the research provides managerial implications for retailers to adopt AR technology as interactive media to enhance customer experience during online shopping in the current and after the pandemic. It is also expected to help government regulation in digital infrastructure to support AR implementation in industry and users’ data privacy. In addition, the research contributes to theoretical development in AR adoption, interactive marketing, and consumer behavior.

Published: April 2022

Shopping through e-commerce is one of the new tools in the current era. Various brands offer the large selection of products or services making shopping through e-commerce like shopping in the city center, but online. Currently, many e-commerce companies are running similar services because e-commerce is important to build a strong brand from the audience and shows the value of the products or services they offer. The aim of the research is to see how significant the influence of Shopee’s brand equity is on consumer purchasing decisions in Indonesia. The research applies a quantitative approach with linear regression analysis to see the causal relationship between variables, with the help of the SPSS 23 application for windows. Data are collected by distributing structured questionnaires online to 100 respondents from various segments of age, gender, and area of residence. The results show that the variables of brand equity including brand awareness, perceived quality, and brand loyalty have an influence on consumer purchasing decisions. However, brand association has no effect on purchasing decision. The most influential variable on purchasing decisions is brand loyalty from all the variables used. Moreover, it is suggested that Shopee application managers should pay more attention to factors that affect brand equity since it has a positive and significant influence on online purchasing decisions.

Published: April 2022

To date, the number of e-commerce applications in Indonesia keeps increasing. However, the adoption rate amongst Small and Medium Enterprises (SMEs) is still around 13%. Thus, the research aims to analyze the factors that affect small and medium enterprises’ resistance to adopting online marketplaces in Indonesia by applying the technological-organizationalenvironmental framework, the diffusion of innovations theory, and the innovation resistance model. The respondents are 356 owners of SMEs in Indonesia who have sold their products online through social media or marketplace. The research applies a quantitative approach using an online questionnaire and interview. Then, the covariance-based structural equation modeling method is applied to analyze the data. In addition, the research interviews five SME representatives to gain further understanding and information for the rejected hypothesis. The results show that perceived complexity, owners’ self-efficacy, and enabling conditions are proven to affect perceived behavioral control. Perceived complexity is also shown to affect perceived risk. On the other hand, government support does not affect perceived behavioral control. It is also found that perceived risk and behavioral control affect resistance to adopting online marketplaces. The findings provide recommendations to overcome this situation, such as the simplification of online marketplace features for sellers and improvements in the digital literacy of the owners of SMEs.

Published: April 2022

The main objective of this work was to develop a nanoemulsion based on linseed oil and betulinic acid, stabilized with Pluronic F127 and polyglycerol polyricinoleate, for anticancer applications. The nanoemulsions were synthesized by ultrasound and evaluated for in vitro cytotoxicity, particle size, polydispersity index, zeta potential, morphology, encapsulation efficiency, storage stability, rheology and in vitro release kinetics. In vitro cytotoxicity assays were performed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay (72 h) against HCT-116 (colorectal carcinoma), SNB-19 (glioblastoma), NCI-H460 (lung carcinoma) and L-929 (normal fibroblasts) cells. The determination of 50% inhibitory concentration (IC50) showed an increased selectivity for the emulsified betulinic acid when compared to its free form for the HCT-116 cells. The IC50 values for the synthesized nanoemulsions showed a range from 3.2 to 3.7 μM (HCT-116), 5.6 and 11.5 μM (NCI-H460), 5.8 and 7.3 μM (SNB-19) and > 16.5 μM for normal fibroblasts. In the 48 h in vitro release assays, it presented controlled release explained by the Korsmeyer-Peppas model, releasing 572.25 and 619.95 μg of betulinic acid in a controlled way, generating promising perspectives for the prolonged release of betulinic acid in anticancer applications.

Published: April 2022

Alginate (ALG) is a natural polymer used in a wide range of applications. Cerium is a sustainable corrosion inhibitor for many metal substrates. In this study, ALG/Ce3+ hydrogel microparticles are presented as an innovative cerium(III) reservoir system for the smart release of cerium ions. The active corrosion inhibition capacity of the ALG/Ce3+ complex was investigated. Tests using ALG/Ce3+ macrogels (beads) and electrochemical experiments showed that, in saline media, ALG/Ce3+ hydrogel was able to release Ce3+, which was subsequently exchanged with Al3+, Fe2+ and Fe3+ and, thus slowing the corrosion process of AA2024 (aluminum alloy) and AISI1020 (carbon steel) substrates, respectively. It is suggested that the presence of metal ions originated from the corrosion process triggers the cerium release. The corrosion protection of ALG/Ce3+ of the aluminum alloy was confirmed by polarization curves, electrochemical impedance spectroscopy (EIS) and scanning vibrating electrode technique (SVET) and the protection of the carbon steel was demonstrated by EIS experiments. To the best of our knowledge, this is the first time that an alginate-based complex has been reported as an ion exchange corrosion-inhibiting system for metal substrates.

Published: April 2022

The theory of adjoint operators is widely used in solving applied multidimensional problems with Monte Carlo method. Efficient algorithms are constructed using the duality principle for many problems described in linear integral equations of the second kind. On the other hand, important applications of adjoint equations for designing experiments were suggested by G.Marchuk and his colleagues in their respective works. Some results obtained in these fields are also generalized to the case of nonlinear operators. Linearization methods were mostly used for that purpose. Results for Lyapunov-Schmidt nonlinear polynomial equations were obtained in the theory of Monte Carlo methods. However, many interesting questions in this subject area are remained open. New results about dual processes used for solving polynomial equations with Monte Carlo method are presented. In particular, an adjoint Markov process for the branching process and the corresponding unbiased estimate of the functional of the solution to the equation are constructed in a general form. The possibility of constructing an adjoint operator to a nonlinear one is discussed.
Multiplicative property of series used in the Nevanlinna-Pick problem
Authors:   St. Petersburg Electrotechnical University LETI, Zheleznyak Аlexander V.
Published: April 2022

In the paper we obtained substantially new sufficient condition for negativity of coefficients of power series inverse to series with positive ones. It has been proved that element-wise product of power series retains this property. In particular, it gives rise to generalization of the classical Hardy theorem about power series. These results are generalized for cases of series with multiple variables. Such results are useful in Nevanlinna – Pick theory. For example, if function k(x, y) can be represented as power series Pn≥0 an(x¯y)n, an > 0, and reciprocal function 1/k(x, y) can be represented as power series Pn≥0 bn(x¯y)n such that bn < 0, n > 0, then k(x, y) is a reproducing kernel function for some Hilbert space of analytic functions in the unit disc D with Nevanlinna – Pick property. The reproducing kernel 1/(1 − x¯y) of the classical Hardy space H2(D) is a prime example for our theorems.
L-optimal designs for a trigonometric Fourier regression model with no intercept
Authors:   St. Petersburg State University, Melas Vyacheslav B. , Shpilev Petr V. ,   St. Petersburg State University
Published: April 2022

This paper is devoted to the problem of constructing L-optimal designs for a trigonometric Fourier regression model with no intercept. The paper considers diagonal matrices L with a combination of zeros and ones on the main diagonal. It is shown that in the case when L = I (i. e., when the unit matrix is chosen as the matrix L), the L-optimal design coincides with the D-optimal one. In the more general case (when some diagonal elements are equal to zero), it is shown that the dimension of the problem can be reduced if the optimal design is symmetric. The obtained results are illustrated by the example of the problem of constructing two L-optimal designs for the trigonometric model of order 12, which is reduced to the problem of constructing designs for models of order 3 and 4 correspondingly.

Published: April 2022

The paper considers a quadratic programming problem with a strictly convex separable objective function, a single linear constraint, and two-sided constraints on variables. This problem is commonly called the Convex Knapsack Separable Quadratic Problem, or CKSQP for short. We are interested in an algorithm for solving CKSQP with a linear time complexity. The papers devoted to this topic contain inaccuracies in the description of algorithms and ineffective implementations. In this work, the existing difficulties were overcome.
On a strong form of the Borel-Cantelli lemma
Authors:   St. Petersburg State University, Frolov Andrei N.
Published: April 2022

The strong form of the Borel-Cantelli lemma is a variant of the strong law of large numbers for sums of the indicators of events. These sums are centered at the mean and normalized by some function from sums of probabilities of events. The series from probabilities is assumed to be divergent. In this paper, we derive new strong forms of the Borel-Cantelli lemma with smaller normalizing sequences than it was before. Conditions on variations of increments of indicators become stronger. We give examples in which these conditions hold.

Minimax stabilization of the line-of-sight of an inertial object on a moving base in the presence of friction force
Authors:   Central Aerohydrodynamic Institute named after N.Y. Zhukovsky, Latonov Vasilii V.
Published: April 2022

The solution of the problem of optimal stabilization of the line-of-sight of an inertial object in the vicinity of the program trajectory is given. The motion of this line is described by a system of nonlinear differential equations of the fourth order. The system of equations is linearized in the vicinity of the desired motion mode. In the problem solved, the perturbations are represented as deviations of the initial position from zero, as well as in the form of constant perturbations. The stabilization is carried out by means of linear feedback. In the problem, the feedback coefficients are calculated as optimal for the worst possible disturbances. Calculations are performed in two ways: a search of all possible combinations of parameters with a given sampling step and a parallel genetic algorithm.
Optimization of oscillation damping in systems with a non-integer number of degrees of freedom
Authors:   Peter the Great St Petersburg Polytechnic University, Smirnov Alexey S. ,   Institute of Problems of Mechanical Engineering of the Russian Academy of Sciences, Muravyov Alexander S. ,   JSC “Gazprom orgenergogaz”
Published: April 2022

The paper discusses issues related to the choice of the optimal damping for a system with one and a half degrees of freedom - a pendulum with an elastic-movable suspension point in the presence of viscous friction. Maximization of the degree of stability of the system is taken as an optimization criterion characterizing the efficiency of damping oscillations. Two options for installing a damping device are discussed - either in the pendulum joint, or parallel to the elastic element. The analytical solution of the optimization problem is performed in each case, and it is accompanied by a visual graphic illustration. In addition, a comparison of two cases of damping is given on the basis of analysis of the maximum degree of stability and a conclusion about the advisability of using one or another option is made. The obtained results are of interest both in theoretical and practical terms, and the described plan for finding the optimal solution can also be applied to solving other optimization problems in systems with a non-integer number of degrees of freedom.
DREAM POETICS IN THE LYRICS OF IVAN ZHDANOV. ARTICLE ONE
Authors: CHIZHOV Nikolay S.
Published: April 2022

The purpose of the article is to show, through a commentary on four poetic texts in the book “Air and Wind”, the features of I. Zhdanov’s artistic modeling of the metaphysical reality of a dream, its main philosophical and literary context, the associated features of the poet’s worldview and the poetics corresponding to them. We conclude that when the poet shapes metaphysical reality he appeals to folklore and mythological sources (dreams perceived as death as reflected by Russian proverbs, myth about the son of the Thunder-God, tradition of serious laughter etc.), to the religious and philosophical heritage of P. Florensky, psychoanalytic tradition ( Z. Freud, K.-G. Jung, and others), and the artistic experience of classical and non-classical authors (A. S. Pushkin, F. M. Dostoevsky, A. Dante, symbolist poets, the inside-out theory by K. Kedrov). We argue that the event-driven development of the dream in the texts under consideration follows the logic of the mysterialarchaeoplot of death and rebirth. For instance, in the poem “The Soul Will Wake Up And Then…”, the folklore character of Alionushka falls asleep as if immersing into whisper-death, and her dream is projected onto the journey of Dante and Virgil in the “Divine Comedy” through the funnel-shaped hell. P. Florensky analyzed this dream within the laws of probability theory, non-Euclidean geometry, and “reversed” time, which is directed to the absolute beginning, going from consequences back to causes. The intersubjective organization and neosyncretic images of the dream-oriented poet’s texts are interpreted in the article from the point of view of historical poetics and Jungian dream theory. In particular, the first verse in the text “Before the Word” (“You are a stage and an actor in an empty theater”) refers to a dream as a theater, where the dreamer is simultaneously a play-writer, an actor, and a stage, as it was understood by the Austrian psychoanalyst. In conclusion, the article states that the poetics of the dream in Zhdanov’s works have modernist origins and are contingent on the author’s creative way of thinking.

The article deliberately addresses the issue of self-consciousness of I. A. Krylov the fabulist. It identifies the factors that contributed to the concentration of an already mature poet, playwright and prose writer on work in a particular genre, as well as the impulses of his entry into the specifics of the fable and the world genre tradition in the conditions of the formation of an internal request for the status of a national poet and the authority of expressing folk wisdom.
The crystallization of the macro-intention of Krylov’s nine books of fables, the identification of the strategy of his book-making is understood as the explication of the dynamics and structuring of the author’s self-awareness, his aesthetic and poetological purposefulness and value success in Russian culture on the transition from the traditionalist to the individual creative paradigm of the development of artistic literature. The meaningful component of the fable is seen as a system of requirements for the arrangement of the peacekeeping apparatus of the master of the word and the possibilities of the national speech tradition to respond organically to the common challenge.
Krylov’s subjectivity is seen as a purposeful process of building oneself as a national and competitive global figure into a number of the highest representatives and exponents of the wisdom of mankind. The authors of the article proceed from the fact that the type of self-consciousness of the fabulist pre-establishes the synthesis of nature, society and the individual, striving for a reasonable, orderly and optimistic coexistence, taking into account the genetic experience of universal metaphor and aphorism, genre inclusions of sentimentalism and romanticism. The links in the promotion of Krylov’s individual artistic system are also fixed, in particular his comedic practice, as a prerequisite for the transition to the decisive choice of the form of aesthetic expression. The research methodology is focused on combining elements of cultural, historical-genetic, semiotic, typological approaches to the analysis of literary phenomena with a common frame of achievements of Russian historical poetics.
CODE-SWITCHING AND CREATIVE PROCESS: PUSHKIN’S PLANS “THE GUESTS WERE ARRIVING AT THE DACHA”, “THE RUSSIAN PELHAM” AND “IN THE WATERS OF THE CAUCASUS”
Authors: HOLTER JULIA , Chepiga VALENTINA P.
Published: April 2022

Alexander Pushkin’s code-switching is a particularly interesting, anachronic or historic example from the early modern period. It is established that he used French language (analytical and well-established) for planning, and the Russian language (expressive but in need for renewal and normalization) as language of textualization.
The genetic exercise proposed here will nuance the above division, pointing at the limitations of functional separations. Today, we know that bilingual writers are guided parallelly by both languages in their creative process, though their functions may be different. They are also inspired by other “voices” that constitute other creative vectors (other languages, music, images…). But can this be demonstrated for Pushkin if the majority of his survived plans were formalized in French?
The plans for three texts, “The Guests Were Arriving at the Dacha” (1828), “The Russian Pelham” and “In the Waters of the Caucasus” (1831), display abundant cases of code-switching between Russian and French, as well as between writing and drawing. We will endorse Youri Lotman’s vision of code-switching as “auto-communication” on different channels (linguistic or not) to show how the ideas bouncing off the linguistic units, but also sparking thanks to the mnemonic function of drawings, establish a current, and a creative tension between different channels of auto-communication.
DIFFUSENESS AND DIFFERENTIATION OF STYLISTICS OF SCIENTIFIC TEXT AND SPEECH STUDIES
Authors: KOTYUROVA Maria P.
Published: April 2022

The article represents the methodological problem that concerns the hypothesis on the possibility to differentiate adjacent scientific directions — stylistics of scientific text and speech studies. The explanatory discourse approach (cognitive, discourse, stylistics) is based on the concept of functional stylistics that is being developed by the Perm Scientific School (Professor M. N. Kozhina). The hypothesis represents the semantic structure of scientific text correlated with its extralinguistic base. This base is concretized through scientific knowledge and defined with cognitive and communicative activities of a subject towards an object. The communicative and cognitive activities of a subject are complexes of extralinguistic factors that have different levels of abstraction in a particular epistemic situation. This level of abstraction is a methodological instrument that provides differentiation of those scientific directions. The stylistics has its own niche — research of language units as well as grammar and functional semantic categories in the framework of functional styles. These styles are influenced by abstract factors — public conscience, areas of activities, cogitation. The stylistics of scientific text is a fragment of modern functional stylistics, it deals with extralinguistic factors and text formation. Speech studies concern the research of unlimited dynamic space of speech and texts (not necessarily scientific ones). This space is interpreted according to dominant discourse factors (strong but not style-forming).

Published: April 2022

At the present stage of the development of Russian society, which is carried out in the conditions of a tense foreign policy situation, the deterioration of the socio-economic situation, additionaly associated with the spread of COVID-19, protracted transformation and modernization processes, the problems of the younger generation in the field of socio-political activity and the formation of appropriate values are particularly acute.
The purpose of the article is to identify and describe the structure of socio-political values of the youth, as well as latent factors affecting the construction of a hierarchy of values of the youth.
Due to the fact that the modern young generation is very differentiated by the level of education, culture, financial situation, socio-professional status, the authors used methods of generalization, comparison, causal analysis in the present research.
The article presents the results of the authors’ sociological study “Socio-political activity of the youth aged 25-35 years of Ulyanovsk” conducted in July — August 2021 and carried out with the financial support of the Ulyanovsk Public Foundation “Regional analytics. Professional research. Ratings” (RAPIR), part of which was dedicated to the study of the structure of socio-political values of the youth.
To collect sociological information, the method of a sociological survey in the form of a questionnaire using the Quizer service and focused interviews in groups was used. To structure socio-political values of the youth aged 25-35 years of Ulyanovsk, a score-rating scale was applied. The factor analysis made it possible to identify hidden (latent) factors influencing the construction of a hierarchy of values among young people and making it possible to typologize groups of the Ulyanovsk youth aged 25-35 years with different levels of presence of socio-political values.
The article demonstrates that the system of socio-political values of the youth has a complexly differentiated structure; most of the values are verbally declarative in nature with a strong paternalistic orientation and the predominance of individual values over collective ones.
WAS THERE A REFORM: TO THE QUESTION OF THE LEGAL SIGNIFICANCE OF THE AMENDMENTS TO THE CONSTITUTION OF THE RUSSIAN FEDERATION OF 2020
Authors: Kim Yuriy V.
Published: April 2022

The question of whether a major change in the text of the Russian Constitution in 2020 can be considered as a constitutional reform is not that simple. Usually, reforms are preceded by thorough preparation. Successful reforms require adequate organizational, legal, doctrinal and human resources support. Objectively, the need for a systematic adjustment of the text of the Constitution was growing in Russian society. The societal demand for constitutional reform has been developing since the moment the Constitution was adopted. This is due to many flaws and gaps that were found later during its implementation. At the same time, the process of transformation of the Constitution started unexpectedly for society, passed quickly, did not have proper support and led to contradictory results. The purpose of this research is to analyze organizational and legal, doctrinal as well as formal and legal aspects of the innovation based on scientific methods. Moreover, deviations from the due legal procedure for amending stated by the Constitution itself and other laws are identified. The methods used for the constitutionalization of legislation, violation of the structural and content-related integrity of the text, technical and legal errors, the legal significance of the plebiscite on the approval of amendments to the Constitution of Russia are critically assessed. In this regard, the question of the state of constitutionalism in Russia and possible measures to strengthen it remains relevant.
