MYTHOLOGY OF ACCOUNTING AND EVOLUTION OF ITS THEORY AND PRACTICE

M. L. Pyatov
Saint Petersburg State University, Saint Petersburg, Russian Federation
Keywords: accounting, myth, information, data, economic life, theory, science, accountant

Abstract >>
The article offers an approach to consideration of the evolution of theory and practice of accounting and assessment of their adequacy to the modern conditions of economy management on the basis of the myth theories by R. Barthes (1915-1980), M. Eliade (1907-1986) and A. Losev (1893-1988). The notion of the mythology of accounting is introduced. The mythologization of accounting practice is considered as a factor of conservatism of the methods of accounting modeling of economic life of an enterprise. A number of famous theoretical constructs in the accounting field are explained as elements of its myth. The offered work can be presented as an invitation to the discussion of possible demythologization of accounting for the purposes of assessment of the perspectives of its evolution as an integral part of the information base of economic relations. The author considers the myth as a tool for understanding of accounting as the phenomenon in evolution of economic life of society.

Novosibirsk State University of Economics and Management, Novosibirsk, Russian Federation
Keywords: complexity, perplexity, scientific rationality, concept of complexity, determinant of perplexity, self-organizing system, adaptation

Abstract >>
Addressing the issue of «complexity» and «perplexity» categories is caused by the evolution of system types ranging from well-organized to self-organizing, expanding the horizons of scientific rationality. Development of governance systems is revealed through the dichotomy of properties and restrictions within the «organizational set-up» and «external influence» notions. It was shown that the governance system falls into the category of complexity because the system is operating on the edge of «order and chaos». External environment is presented as chaos analogue showing uncertainty and changes of various fluctuation category, up to turbulence. The incorporation of social and economic system into external environment was considered from the perspective of formation of «system convergence» of two open systems, contributing to growth of the degree of complexity of governance system. It was emphasized that business development forces perplexity governance systems to switch to robust control; the mechanism of robust control is organized under the influence of the laws of evolution and survivability of biosystems. The following methods were marked out and justified: selection of parameters for system convergence of governance system with external environment entities, determination of limits of information granules of adaptive and robust homeostasis, scenario planning, construction of convergent strategy and temporal attractor of system equilibrium state, known as «floating equilibrium». These methods are to be mastered by the governance system within robust control.

Keywords: human capital, innovation, innovative development, scientific and technological development, sixth technological order, education, investment, GDP

Abstract >>
The purpose of the study is to study the relationship between the level of human capital and innovative development in various countries of the world in the context of the transition to the sixth technological order. When studying the relationship between human capital and innovation development, the authors formulated a hypothesis about a significant difference in the sensitivity and impact of innovation on the level of human capital for different groups of countries. To test the hypothesis, the authors used analytical, statistical, and correlation-regression analysis methods. The combination of these methods allowed us to record a different degree of relationship between the level of human capital and GDP, human capital and innovation, innovation and GDP of Russia. According to this analysis, in Russia there is a close relationship between the level of human capital and GDP, a less close relationship between innovation and human capital, and a very weak relationship between innovation and GDP. The current situation for Russia in the context of changing technological patterns requires special attention from state institutions to solve this problem. For the purpose of innovative development of Russia, the authors proposed measures for six major areas. The results obtained can be used to justify proposals and measures to regulate innovation processes, taking into account the priority of national interests of scientific, technological and economic development of the country.

ON THE EXTREMAL DEPENDENCE COEFFICIENTS OF GAUSSIAN DISTRIBUTIONS

S.E. Khrushchev
Novosibirsk State University of Economics and Management, Novosibirsk, Russian Federation
Keywords: copula, Gaussian distribution, extremal dependence coefficients, COVID-19 coronavirus infection

Abstract >>
The paper considers a way to represent the relationship between indicators in the form of copulas. Copulas are popular mathematical tools. This is due to the fact that, on the one hand, the marginal distributions of indicators are divided in the copulas, and on the other hand, the structure of the relationship between these marginal distributions is divided, which makes it possible to very effectively study the connections that arise in real populations. Special attention in the work is paid to extremal dependence coefficients - important numerical characteristics of the connection in conditions of extreme small or extremely large values of indicators. It is shown that even under conditions of close correlation between the indices for a two-dimensional Gaussian distribution, the lower and upper coefficients of the extreme dependence take zero values. This indicates the impossibility of predicting the values of one indicator when fixing too small or too large values of another indicator. This work shows that the relationship between the number of COVID-19 coronavirus infections per 100,000 people and the number of deaths from COVID-19 coronavirus infection per 100,000 people in the regions of the Russian Federation can be represented in the form of a Gaussian copula.

Keywords: maternity capital, birth rate, population reproduction, demographic policy, reproductive behavior

Abstract >>
In Russia, in 2007, the Concept of Demographic Policy for the period up to 2025 was developed and approved. One of the key tasks is to increase the birth rate of the population. The measures taken to stimulate the birth rate of the second and subsequent children in the family do not bring the desired result. By 2019, the birth rate in the country again fell to the «pre-reform» level. The article is devoted to the description of the main theories that explain the current situation with the birth rate not only in Russia, but also in the world as a whole: A. Smith’s feedback paradox, the theory of social capillarity by A. Dumont, Caldwell’s theory of flows of goods. The concept of reproductive behavior is considered.

FAMILY INSTITUTE IN THE SYSTEM OF FORMATION AND REPRODUCTION OF SOCIAL INEQUALITY

N.A. Vyalykh
Southern Federal University, Rostov-on-Don, Russian Federation
Keywords: social inequality, family institute, marriage and family relations, family capital, social mobility, social stratification

Abstract >>
The article reveals methodological guidelines of the scientific study of family relations as a space for the formation and reproduction of social inequality in society. It is proved that the family, despite the nominal transparency of social mobility channels in societies with an open system of social stratification, continues to have a decisive influence on the distribution of status positions. The limitation of the modern concepts of family institute’ role in social differentiation is connected with the reduction of social inequality to objective factors, although it should rather be about the result of influence of the social situation or individual traits, social values, attitudes and cultural predispositions. It is shown that there is a methodological turn from quantitative sociological assessments of socio-economic and educational differences to qualitative interpretive practices in familistic studies that allow revealing the deep socio-cultural factors of inequality. The author comes to conclusion about the methodological pluralism in family sociology as a potential source of ambivalence of the state family policy on eliminate excessive social inequality.

Keywords: education, distance learning, verbalized and non-verbalized traditions, explicit and implicit knowledge, lecturer, student, personal knowledge

Abstract >>
The modern educational process is focused on the training of a specialist who is able to think critically and creatively solve problematic situations, constantly raising the level of his education. Education as the most important social institution reacts sharply to the processes taking place in society. Actively developing distance learning is quite popular today, but there are different kinds of questions related to its implementation and the significance of a personal example, personal contacts in the learning process is one of the questions that is analyzed in this article. Would the distance learning be complete if it was deprived of subjectivity by definition? The educational system is understood to be a tradition in the article. The authors stress two types of traditions: verbalized and non-verbalized. The specificity of pedagogical activity does not allow many of its significant components to be explicated. The attention is focused on non-verbalized traditions existing in the form of implicit knowledge. Specific examples (V.I. Vernadsky, V.V. Dokuchaev, P.V. Ototsky) reveal the necessity of personal knowledge in the educational process. The article concludes that personal communication between the lecturer and the student is necessary as a conscious movement against deindividuation in modern society.

National University of Science and Technology, Moscow, 119049 Russia
Keywords: Coal, failure, cyclic freeze-thaw, ultrasound, P-wave, spectrum processing

Abstract >>
The samples of anthracite and bituminous coal are studied in cyclic freeze-thaw at different water contents. In the freeze-thaw cycles, the samples were subjected to continuous ultrasonic sounding. It is found that different contents of water have an essential influence on the spectrum of recorded signals. Regarding the water-unsaturated check samples, the spectrum change is reversible, and the freeze-thaw treatment results in no failure. An increase in the water content of the samples fosters the irreversible change in the spectra of the signals against the background of macro-cracking along stratification planes. Anthracite exhibits higher persistence to freeze-thaw damage than bituminous coal.

Institute of Oil and Gas Problems, Russian Academy of Sciences, Moscow, 119333 Russia
Keywords: Hydraulic fracturing, coal seam drainage, rock stress-strain behavior, annular space unsealing, borehole reaming, bow springs centralizer

Abstract >>
The article discusses the mathematical modeling results on formation of concentration zones of failure stresses in annular space of a well during hydraulic fracturing of productive formations from vertical or nearly vertical boreholes. The rigid connection between the cement lining and rocks fails because of a thin clay layer in-between, which leads to unsealing of the annular space and to various troubles, including environmental implications. To prevent annular space unsealing during hydraulic fracturing, it is proposed to ream out borehole in the area of contact with the productive stratum roof, and to install a bow springs centralizer on this level then.

Keywords: Gas pressure, outburst coal, uniaxial compression strength, energy accumulation and release, fractal dimensions of crack

Abstract >>
Uniaxial compression test of outburst coal was conducted to explore the mechanical characteristics of coal with outburst tendency in low gas pressure environment. The mechanical properties of coal were analysed, the surface crack morphology of coal was obtained and the energy characteristics of coal during loading were determined. Results are as follows. In the pressure range of 0.03-1.0 MPa, the uniaxial compressive strength and elastic modulus of coal show a negative exponential relationship with pressure, and both decrease with the increase in pressure. With the increase in gas pressure, the angle between the failure surface and horizontal surface of coal body increases gradually. With the increase in gas pressure, the fracture morphology of coal failure tends to be complex. When the gas pressure is low, the coal can store a large amount of energy, and its ability to resist damage is greatly improved.

Abstract >>
In deeper level mining in Tashtagol deposit, during extraction of ore reserves from safety pillar, the stresses and inelastic strain zones increase 2-4 times. In safety pillar in Sheregesh deposit, the tensile stress zones, where failure of undermined rocks intensifies, enlarge as mined-out stoping void grows. During mining in the Eastern and Northwestern sites of Tashtagol deposit, at the tunneling speed of 2.0-2.5 m/day and more, rock bumps of energy class 5-6 are recorded. In mining of Podruslovy and New Sheregesh sites, the decrease in the energy class of rock bumps is achieved at the tunneling rate of 0.4-0.6 m/day. The feasibility and sequence of safe extraction of ore reserves from safety pillars established under the Kondoma and Bolshaya Rechka rivers are justified. The backfill options in extraction of ore reserves from safety pillars in Tashtagol and Sheregesh deposits are discussed.

The lack of the correlation between the hydrophobic behavior, characterized by the wetting angle, and the floatability of minerals, as well as the correlation between the inductance time and the mineral recovery are discussed. The causes of disagreement between the collectability sequence of xanthates, dithiophosphates and dithiocarbamates and the sequence of boost in energy of chemical bond between these reagents and cation of mineral lattice are exposed. Collectabilities of frothers and residues of the collectors are explained. The ways to increase flotation performance are shown, namely, the mineral recovery and the concentrate quality can be improved by means of adjustment of the chemisorbable /physisorbable collector ratio.

Abstract >>
The capacity of novel selective dithiocarbamate collectors, namely, morpholine dithiocarbamate (MDTC) and S-cyanoethyl N, N-diethyldithiocarbamate (CEDETC) to form complex compounds with gold on the surface of sulphide minerals containing fine gold under conditions of flotation is experimentally proved. MDTC adsorption at the surface of chalcopyrite without gold takes places due to formation of morpholine dithiocarbamate copper. At chalcopyrite and arsenopyrite containing gold fines, MDTC-Au and CEDETC-Au compounds are formed. MDTC and CEDETC improve floatability of gold-bearing sulphides as against gold-free minerals, which is beneficial for the production of Au-Cu concentrates with lower content of As and Fe by flotation.

Abstract >>
In this article, the recovery of the Y, La, Nd, and Ce rare-earth elements (REE) from apatite concentrate by acid leaching and digestion-water leaching processes were studied. The maximum REE recovery of 62% in the acid leaching process with sulfuric acid was obtained for La in the condition of 12 M acid concentration, leaching time of 4 h, process temperature of 25℃, and a liquid to solid ratio (L/S) of 1:5. In the optimal conditions in terms of process (220℃, 3 h and L/S (1:2)), the digesting process in the presence of sulfuric acid led to the recovery of La, Ce, Nd and Y at 93.92, 92.22, 92.04 and 91.00%, respectively. In contrast, the aqueous leaching process in the optimum conditions, including a leaching time of 5 h, at 80℃ and L/S of 1:10 ended up recovering the La, Ce, Nd, and Y at 89.50, 88.45, 92.20 and 94.0%, respectively.

Abstract >>
The authors compare the effect exerted by copper ions and sulphide copper nanoparticles on flotation of Gorevskoe deposit sphalerite using potassium n-bytul xanthate and in reagent-less regime. Covelline-like colloid particles 4-8 nm in size, obtained in interaction of copper (II) and sulfide ions in aqueous solutions, are characterized using the methods of dynamic light scattering, electron microscopy and diffraction. Sphalerite surface after reaction with copper ions and CuS dispersoid solutions are described by zeta-potential measurements and X-ray photoelectron spectroscopy. It is found that sphalerite flotation after activation with nanoparticles is lower than with copper ion solutions of the same concentrations, and improves with increasing duration of activation and flotation processes. The mechanism of CiS nanoparticles consists in creation of active centers for the collector to attach to, which intensifies the hydrophobic behavior and adsorption of the collector. Moreover, CuS nanoparticles promote formation of a special microrelief of the solid-liquid interface, which ensures rupture of liquid film and attachment of sphalerite particles to air bubbles when they collide.

Abstract >>
The subcool zone length is determined in lining of an extra-long railway tunnel subjected to deep influence of piston effect. The air temperature distribution in the outer air-tunnel lining contact zone is determined as function of the velocity of train and the outdoor temperature in the cold season. The authors review the de-icing methods of tunnel lining: warming-up using a self-tuning heating cable; arrangement of an unheated access gallery and heat insulation. The distribution of the hourly average air temperature in an extra-long railway tunnel is analyzed against of sites of fan heaters. The heat power patterns in the tunnel are estimated by the criterion of the required temperature conditions. It is shown that the most efficient arrangement of fan heaters to maintain the required air temperature in the tunnel is their uniform distribution along the length of the tunnel in combination with installation of warm air curtains at the tunnel faces.

Keywords: engineering education, convergent approach, metasubject training results, disciplinary convergence of engineering university, interdisciplinarity, discipline-concentrate, metasubject construct, levels of synthesis of scientific knowledge

Abstract >>
Introduction. The organization of training at an engineering university requires the use of modern ideas about convergence as a fundamental category for the creation of integral educational spaces that implement an interdisciplinary synthesis of humanitarian, natural science and technological knowledge. This approach will best ensure that the metasubject learning outcomes are achieved. Methodology and methods of the research. The methodology of the system approach was used as a general scientific base, which allows to form a universal matrix of cross-disciplinary integration of engineering training. To organize the information integrity of polytechnic knowledge, the methodological functions of the concept of the modern picture of the world are “included”. The results of the research. The idea of convergence in education as a methodological basis of a holistic scientific worldview, emerging through the implementation of cross-disciplinary synthesis of scientific knowledge, is revealed. It has been shown that the metasubject results of training are considered as a worldwide visual interpretation of the goal of the modern educational system. The importance of a convergent approach for the pedagogical system of an engineering university that genetically integrates humanitarian, natural science and technological knowledge is justified. The author’s results of the study of the specifics of the general theory of systems in the development of the algorithm for the integrated design of the integral educational space of polytechnic training are presented. A general formative basis for cross-disciplinary interaction has been identified - methodological competence. It was shown that the metasubject results of training directly correlate with the idea of the formation of the foundations of the scientific worldview as methodological principles for studying any processes and phenomena. The procedure of modification of content of educational subjects and organization of process of assimilation is presented, focused on formation of methodological bases of engineering knowledge as the fundamental component of meta-skills. As a system-forming design, a category of technical system has been identified, the organization of the presentation of which in the cycles of polytechnic training allows all forms of synthesis of scientific and substantive knowledge of engineering to be realized. It has been shown that the technology of achieving metasubject training results does not involve restructuring the traditional structure of the educational process, since the goal of the pedagogical system is mainly focused on the organization of specialized methods for presenting educational information through algorithms of logical analysis and synthesis of fundamental engineering knowledge. Conclusion. Using a convergent approach to organize the integral educational space of an engineering university allows you to most effectively solve the problem of forming ideas about the integrity of the picture of the world and the principles of working with it. According to the author, the proposed approach to the transfer of scientific and substantive information ensures the implementation of the individual educational trajectory of the trainee, focused on the development of self-education skills as a global social order.

Keywords: cognitive linguistics, psycholinguistics, linguodidactics, semantics, analytical philosophy, anti-mentalism, conceptual models, conceptual metaphor, experientalist realism, concept, prototype, cognitive structure, mental representations

Abstract >>
Introduction. The paper discusses the issue of applying the results of cognitive linguistics to linguodidactics. The cognitive approach to teaching a foreign language assumes that the student comprehends the mental structures that control the linguistic thinking of the native speaker of this language, and it enables him to master it. However, the question arises as to both the validity of cognitive linguistics itself and the possibility of using it for linguodidactic purposes. The aim of the article is to discuss these issues. Methodology and methods of the research. The methodological basis of the study is the ideas of some analytical philosophers concerning the essence of cognition and the formation of scientific knowledge. They are primarily the analytical authors who developed their ideas in the spirit of epistemological relativism, conventionalism and anti-mentalism. The results of the research. The paper shows how the criticism of mentalism can affect the assessment of cognitive linguistics and the potentialities of its use in linguodidactics. First, the critical observations on cognitive linguistics by representatives of various branches of linguistics are discussed. Then a criticism from the standpoint of the anti-mentalist philosophical methodology is expressed. It is also from the perspective of the anti-mentalist methodology that the way cognitive linguistics is applied to the field of linguodidactics is criticized. It is said that the reference to mental representations, while developing and using cognitive models in the course of educational process, cannot be considered scientifically relevant and the use of such models does not make acquiring a foreign language much easier. Conclusion. It is concluded that the cognitive approach to teaching a foreign language does not quite correspond to its name, since it is not sufficiently cognitive and does not reflect the real cognitive processes in the human mind. However, this method can be used as a heuristic technique that could contribute to the acquisition of a foreign language.

Abstract >>
Introduction. This article analyzes the impact of the coronavirus pandemic, which spread widely around the world in early 2020, on education. It is shown to have led to the near complete paralysis of schools, colleges and universities. What is the state of health of students and how they assess the quality of higher education provided by their universities is the focus of this article. Methodology and methods of the research. The methodological basis was a theoretical analysis and systematization of the provisions of philosophical, sociological and pedagogical literature in the aspect of the object of this research; comparative historical analysis of the problem under study; study of official materials, policy documents in the field of general and higher education systems related to the modern coronavirus pandemic; foresight study of the future prospects of education in the “post-like era” and the importance of the philosophy of education in this process. The results of the research. Tracing the scientific research literature of recent times, the realization comes that the education that was before the pandemic will never be. And there is still no understanding of this education in the scientific literature. There are various approaches to post-image education based on digital technologies, based on the principles of subjectivity and objectivity of the nature of the value of informational distance, online forms of education. From the point of view of subjectivity, the value of an object is determined by the subject, and in this case, value can be interpreted as a feeling. Representatives of objectivism either derive the definition of the value of digital education from being, or believe that values have an independent significance, which is discussed in the article. There were interviewed 200 students from various universities in Almaty. The study also analyzed modern scientific literature on the image of “post-like” education, identified the main trends in distance education. Conclusion. A new type of education is currently emerging. The article attempts to analyze the degree of student satisfaction, identify the main problem points in distance education through their eyes, as well as the main trends in the field of education in the post-like era.
