Introduction. The main task in the development of mineral deposits by open and underground methods is to ensure the safety of mining operations. As a result of long-time standing of the pit walls in the near edge zone massif, changes in natural stresses can occur, which lead to deformations. Prediction and prevention of deformation processes of the near-rock massif largely depend on reliable information about its structural features, including the structure of the massif and the degree of its disturbance. Purpose of research is to assess the possibility of manifestation of deformations from the position of disturbance of the massif. Methods of research. When assessing the possibility of deformation manifestation, a set of methods was used, including: full-scale measurements of fracturing; methods of mathematical statistics using the Stereonet program for processing measurement results; analysis of the spatial position of cracks relative to the direction of strike of the slopes and sides of the open pit with the identification of the most dangerous ones; kinematic analysis, allowing to determine potential types of loss of stability from the position of disturbance of the massif. Result of research. In the southeastern, northern and western sides of the Kamagan open pit, 41 fracture systems have been identified; the prevailing systems are northwestern dip systems at angles of 50 ° –85 °; south-east - at an angle of 50 ° and south-west - at an angle of 50 °. For example, for the northern side (Ap = 90 °; n = 60 °), it was found that potential types of destabilization are: wedge formed by systems of cracks with spatial characteristics Ap = 65 °; n = 45 ° and Apr = 150 °; n = 90 °, and planar sliding formed by systems of cracks with the parameters Ap = 90 °; n = 55 ° and Apr = 100 °; n = 42 °. Conclusions. Studies have proven the need to study and identify weakening surfaces in the process of mining and determine the parameters of their occurrence in order to assess the possibility of deformations and further assess the stability of slopes.

Relevance. Formation of a circular economy assumes a special place among the new realities that fundamentally affect new technological trends in industrial development. Although the concept of this economy is at the stage of formation, many developed countries, primarily the EU countries, necessarily include it in the most important strategic documents for the development of their countries provisions related to the key principles of a circular economy. The strategic planning system in Russia also includes documents based on the use of individual principles of this economy, contains the development and use of possible mechanisms for integrating the requirements of low-waste and low-carbon development into a circular economy. The industrial development of the country has a special influence on the process of transformation of a linear economy into a circular one, the greening of which is largely associated with solving the problem of processing industrial waste. The decisive role in their formation belongs to the country’s mining and metallurgical complex. To date, numerous technological processes for the complex processing of technogenic resources have been developed; there are investment projects in this area. However, there is no modern methodological toolkit for assessing their effectiveness, taking into account the sharply changing world and national conditions, economic conditions. The purpose of the work is to form a methodological approach to assessing the ecological and economic efficiency of processing technogenic formations of mining and metallurgical industries. Methods of research. The methodological basis of the study is a functional approach that allows taking into account the rapidly changing economic conditions. The research methodology is based on the basic provisions of the methodology of real options. Results. A comparative assessment of the formation and processing of wastes from mining and metallurgical production in Russia and the Urals is carried out. A methodological approach to assessing the socio-economic efficiency of processing technogenic resources has been formed. A classification system for the conditions of real options is proposed for assessing the efficiency of processing of technogenic raw materials. Conclusions. The results of the study confirm the feasibility of using the proposed methodological toolkit for assessing the efficiency of processing technogenic resources of various industries. The formed system of classification of the conditions of real options for assessing the efficiency of processing of technogenic raw materials creates the possibility of choosing optimal management decisions.

Relevance. Competition, being a factor of socio-economic progress, improving the quality of goods and limiting price increases, also leads to the bankruptcy of inefficient economic entities. Preventing bankruptcy and ensuring the viability of mining operations in the face of increasing speed of change and increased competition are urgent challenges. Improving the productivity of mining employees is an important factor in ensuring their competitiveness. The purpose of the study is to disclose the concept of labor productivity and substantiate the need for its use in the economic mechanisms of managing mining enterprises. Methods of research. Methods of semantic analysis, structural and functional analysis, scientific generalization, production experiment were used. Results. The concept of labor productivity is the realization of the employee’s ability to produce useful products using his or her labor potential. The role of labor productivity in ensuring the competitiveness and viability of a mining enterprise (ME) is determined. The formula for calculating the labor productivity of ME is given. The market economic mechanism of managing ME divisions and the results of its application are presented. The necessity of developing this mechanism using the indicator “labor productivity” is substantiated. Conclusions. Labor productivity is an indicator that makes it possible to take into account the results of employees’ activities in terms of effective reproduction, timely adaptation and sustainable development of ME, as well as the costs of achieving them. The use of this indicator for the development of a market economic mechanism for managing the units of ME will increase the efficiency of using the labor potential of its personnel and, on this basis, ensure the necessary competitiveness and viability of the enterprise.

Relevance. Ensuring the long-term competitiveness and efficiency of mining enterprises requires increasing the pace of development: the introduction of new technologies, the improvement of labor methods, the implementation of institutional transformations. However, the implementation of the innovation strategy does not occur systematically, at an insufficient pace, with an excess of resource costs and a systematic failure to achieve planned results, due mainly to subjective factors based on contradictions between economic goals and the social policy of the enterprise. Purpose of the study: the formation of standard strategies for the socio-economic development of a mining enterprise, depending on the dynamics of the external and internal environment. Research methods. In the course of the study, the methods of structural-functional analysis, abstract-logical modeling, socio-economic forecasting, production experiment and systems approach were used.. Results. On the basis of the study of the processes of transformation of the mining industry, the general problems hindering the innovative development of enterprises are highlighted. The main reason for such problems is managerial inconsistencies between technical and economic capabilities and motivational mechanisms. Based on the study of the transformation processes of mining enterprises, four standard strategies of socio-economic development have been developed that ensure the transition to sustainable development based on a balanced distribution of limited resources between social and economic goals. Conclusions. The fundamental strategies of socio-economic development are determined by overlapping development cycles of the external and internal environment: concentration, adaptation, evolutionary and innovation. The correct choice of strategy allows making rational management decisions: in crisis conditions - to reduce economic losses, to preserve the assets of the enterprise and the operability of the technological subsystem; in favorable conditions - to realize the potential of the enterprise based on the growth of efficiency and sustainability of its work

Authors:   Ural State Mining University, DUSHIN Vladimir Aleksandrovich
Published: December 2020

Purpose of the work: determination of the geological structure, occurences of magmatism and geodynamics of the northernmost isolated segment of the paleooceanic sector of the Ural mobile belt – the Shchuchinsky megablock. Geographic disconnection with the southern structures of the Ural mobile belt and sub-ring structure have led to both a suspended interest and conflicting ideas about its geology, the composition of the host rock complexes, their age, genesis, and mineragenic specialization. Methodology of the work: generalization, analysis and synthesis of materials of long-term study of geology and magmatism of the region, including the conducted GDP-200/2 sheets Q-42-VII, VIII and GMK-200 sheets Q-42-III with extensive literary sources and creator-owned mineralogical-petrographic and petro-geochemical studies, including isotope-geochronological ones. Results. For the first time, the internal geological structure of the Shchuchinsky megablock, its magmatism, geodynamic conditions of formation and metallogeny are shown on the basis of the created geological map of pre-Mesozoic deposits and the developed author’s legend of the territory. Magmatic, metamorphic and sedimentary formations are combined into pre-Paleozoic (Archean-Proterozoic), Paleozoic and Mesozoic megacomplexes, characterized by specific formational-geodynamic parameters and ore content of their occurences at certain stages of the development of the region. Analytical information on the breed associations of the structure under consideration is given in a concise form. Conclusions. The results obtained indicate a probable polygenic-polychronous structure of the ophiolite association and subsequent island-arc-collisional complexes, including the so-called “femic” (AR – PR) base, involved in the vortex interplate system, which caused the annular structure of the Shchuchinsky ridge

The purpose of the study is to develop methodological approach for identifying changes in the level of insurance companies’ competitiveness on the travel services market. Based on development of multifactor regression equation, integrated indicators of insurance companies’ competitiveness in 2016–2019 were calculated. The application of three-sigma rule allowed to divide insurance companies by competitiveness levels and to identify that during 2016–2019 most of insurers had sufficient and critical levels of competitiveness and the group of insurance companies with a high level of competitive position is small. The Markov chain theory was used as a research method to determine the probability of insurance companies moving to higher or lower competitiveness levels. The results of Markov’s method showed that the majority of insurance companies are most likely to remain in their initial groups and only insurers with low and sufficient competitiveness have high probability to change their positions. Companies with high competitiveness have very strong positions on the market and there is very low probability that other insurers will capture leaders’ market share in the coming years. So, the use of the developed approach allows predicting a decrease of insurance ability to compete on the travel services market and deciding on the necessity to change the competitive strategy.

Dealing With Non-Performing Loans During The Bank Restructuring Process in Vietnam: Assessment Using The AHP and TOPSIS Methods
Authors: Tran Anh Thi Van , Nguyen Nhung Thi , Tran Tu Thi Thanh
Published: December 2020

This article aims to assess the solutions that have been implemented in Vietnam to deal with non-performing loan(s) (NPLs) in the banking system. By trying to build evaluation criteria through a literature review and an expert survey, as well as using the analytic hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS), this research measures the effectiveness of the resolution of NPLs in Vietnam through many factors. The empirical results show that, in the past, the banking system in Vietnam has not dealt very well with bad debt, as it mostly uses traditional methods such as NPL write-offs by loan loss reserves or the liquidation of collateral. Based on our consideration of the NPLs’ resolutions that the Vietnamese banking system has implemented recently, we propose some suggestions to improve the necessary conditions for applying more market-based solutions, such as debt-equity swaps and securitization to thoroughly resolve the NPLs in Vietnam

The article discusses the historiographic aspect of the KalmykTibetan relationships in the second quarter of the XVIII century. There were several significant events in the given period including the arrival to Kalmykia from Tibet of Shakur-lama who was chosen as the supreme lama of the KalmykBuddhists, the sending of the Kalmyk envoys to Tibet in 1729–1735 and in 1737, the giving of the ‘khanate’ muniment to the governor Tseren-Donduk by DalaiLama VII. The article analyzes the author’s publications of the last decade that made a great contribution to the topic research. There are several new significant works on the historiography of Kalmyk-Tibetan relationships including theses and monographs. Among the contemporary research there should be mentioned works of A. A. Kurapov, A. V. Tsuryumov, B. U. Kitinov and E. P. Bakaeva who managed to introduce a great number of unknown before sources on different languages. The further study of the history of the Kalmyk-Tibetan relationships that are relevant nowadays appears to be a high-potential field in the Mongolian Studies.

The research of the problems of the contemporary history of the NorthEastern China including the analysis of ideological and political campaigns of the second half of the XX century is one of the high-potential fields of the Oriental studies in our country. The article focuses on the period of the (Great) ‘Cultural Revolution’ (1966–1976) at bordering USSR Chinese regions — Heilongjiang province and Khulun-Buir aimak of the autonomous region of Inner Mongolia. The goals of the study are set in concurrence with chronological order of the events: the ‘cultural revolution’ in the above mentioned regions had two stages. The study is based on the works of the Chinese historians. The given research highlights the specific features of the initial stage of the “cultural revolution” including the criticism of the party officials, establishment of revolution committees and running a political campaign ‘vasu’; considers the Soviet-Chinese conflict at the Daman island in 1969 to be a factor in the following political stabilization of the bordering territories; examines the movement for restoration of the party apparatus and the boost in the industrial development in 1970s of the last century.

The article analyses the board of people’s deputies system reform at the end of 1980s — the beginning of 1990s on the example of the Republic of Kalmykia. The board of people’s deputies system reform in Kalmykia in the given period developed within the framework of social doctrine vision of the Soviet in the system of country-wide power. These changes reflected the influence of perestroika and were aimed at democratization of the board of people’s deputies work, the rise of their role as the representational body of power and responsibility, specifically the local board, in the solution of social-economic problems of the territories and population. Beginning from 1991, under the influence of Russian reforms there was a gradual transition to the perception of the local board as a local government authority. In 1992, the local government institution was introduced in Kalmykia.
Динамика правового статуса Монголии в XX в.

Published: December 2020

This article is aimed at determining Mongolia’s status based on historical documents and contemporaries’ evaluation. It discusses the change in the legal status of Mongolia from the collapse of Qing Empire till the mid XX century. As it is shown, Mongolia was not part of China but was in vassal — suzerain relationship with the Manchu Dynasty of Qing Empire. Qing ‘new policy’ of Chinese colonization destroyed this relationship which led to national liberation movement of Mongols. Dynasty abdication and the formation of the Republic of China gave new legitimate ground for independence Mongolia. Declaration of independence of Mongolia on December 29, 1911 as the culmination of this movement was legitimate and was not a revolution. The treaty signed in 1912 between Russia and Mongolia may be considered as de jure recognition of the independence but not the autonomy of Mongolia. The rightful recognition of the autonomy was recorded in the agreement of 1915 between Russia, China and Mongolia. Outer Mongolia became the state under the formal suzerainty of China and the protectorate of Russia. The abolishment of autonomy and occupation of Outer Mongolia by China in 1919 was illegal. In 1921 baron R. F. Ungern reinstated the autonomy and in fact the independence of Outer Mongolia. From the take-over of the Mongolian People’s Party until adoption of constitution by the Mongolian People’s Republic in 1924 the country status was undefined. From 1924 until recognition by China in 1946 the Mongolian People’s Republic was de facto independent country with the implied (silent) recognition by the USSR. Reunion of Inner Mongolia and Barga with the Outer Mongolia / Mongolian People’s Republic was the historical choice of their peoples.

Published: December 2020

The article analyzes the antireligious policy of the Mongolian Party and government in 1920s–1930s of the XX century. At the beginning of the 1920s the party and state authorities’ attitude towards religion and clergy was loyal, but from the beginning of 1926 with the adoption of the law about separation of religion from the state, the time of its gradual tightening up began. The attacks on the monasteries manifested in deprivation of their economic independence, taxation, forced conversion of the lamas to laymen, open campaign for “total confiscation of possessions of lamas and monasteries”. These actions of the party and the government obviously aroused protests from the clergy and church that lead to uprising and rebellions. In relation to this the recording of the conversation of the USSR Central Executive Committee presidium member S. E. Chutskaev with the head of the organizational department of the Central Committee of Mongolian People’s Revolutionary Party D. Luvsansharav, former lama, is of great interest. The study is based on the archive materials about Buddhist clergy and church that are presented in the collection of documents “Mongolia in documents from the archives of the Federal Security Service of Russia (1922–1936)”. Out of 163 documents, included into the book, 35 documents are about lamas and the clergy, they introduce a wide range of problems.

The goal of the article is to define the development of the RussianMongolian collaboration in such an important sector as military that started in 1930s amidst the complication of the international situation brought about by the open aggression of the military Japan. The study is based on data from collection of documents and the materials of the Russian State Archive of SocialPolitical History. The research showed that the political and military integration was activated as a result of the marked aggravation of the international situation in the Far East at the beginning of the 1930s due to the Japanese aggression in China, the establishment of the marionette state Mandzhou-Go at the borders of Russia and Mongolia and the emergence of the direct threat to Mongolia and the Soviet territories. It was in the Mongolian steppes, in the Khalkhin-Gol battles for freedom of the Mongolian people where the becoming of the general G.K. Zhukov occurred. Under his command there was an effective interaction of Soviet-Mongolian military units that led to gaining a valuable experience in the allied forces combat.

Labour and the Ecological Critique of Capitalism in Videogames: The Case of Stardew Valley
Authors:   European University at St.Petersburg, Russia, Awagjan A.R. , Kalugin A.A. ,   Independent researcher, Moscow, Russia, Kondrashov P.R. ,   Hanze University of Applied Sciences, Groningen, Netherlands
Published: December 2020

In this paper we conduct an analysis of the critical narratives of Stardew Valley and compare them to other relevant videogames in order to develop new possibilities for an ecological critique of capitalist extractive econo­mies. Critical narratives of this game are aimed primarily at the alienating conditions of labour and deeply devastating modes of production under capitalism that impact and severely damage the environment. Analysing these narratives, we superimpose the immediate messages of the game with the procedural rhetoric and material conditions of their existence. Over the course of our analysis, we highlight a material-narrative disso­nance which, in the case of Stardew Valley, fails to function as a commu­nicative strategy of the game and remains its mere external contradiction. Although the game’s critical narrative may seem overly utopian and its political imaginary a bit underdeveloped, the game elaborates on concrete ways to tackle the alienation of labour and resolve the ecological crisis. In addition to this, the paper covers the history of the interplay between the video game industry and the field of global ecological crisis research. We compare the attempts to raise awareness of the videogames’ own material­ity that preceded Stardew Valley. We conclude that Stardew Valley utilises the language of sustainable co-existence and wasteless local production, expanding this logic both to the sphere of labour and the spectrum of en­vironmental problems. In the case of ecological critique, some gameplay decisions in Stardew Valley enable us to come up with new strategies aimed at creating critical narratives about the environment in videogames. Thus supplementing Stardew Valley’s findings with critical tropes derived from other games (mainly, Rain World), we were able to gather a set of theoretical instruments that could facilitate the creation of games about ecosystems. Following Donna Haraway’s emphasis on the crucial role of narrative fram­ing (“it matters which stories tell stories”), we highlight new opportunities for the entire medium of videogames.
An Analysis of the Ideological Potential of Video Games from the Point of View of James Gibson’s Theory of Affordances
Authors:   Institute of Business and Design, Moscow, Russia, Moyzhes L.V.
Published: December 2020

The purpose of this article is to propose a method for analyzing the ideo­logical content of video games while taking into account the agency of the players. The interactivity of video games as a medium has been attracting the attention of researchers for many years, raising, in particular, the ques­tion of how this unique property serves to broadcast certain ideologies. The ability of games to make ideological statements was discussed by Bogost, Frasca, Aarseth, and many other pioneers of game studies. Video games were analyzed both in the context of older media forms that promoted certain ideas through plots, visuals, and other traditional means, and as unique types of objects that can make statements through rules. I aim to introduce the player — as a subject who is able to transform and conceptual­ize the game based on their own cultural background — to this discussion. Using James Gibson’s theory of affordances, I want to acknowledge the player’s freedom of interpretation, the potential to assign one or another ideology to the game in each playthrough. On the one hand, the player acts as a consumer of content; on the other hand, they are a co-author who will use the tools offered by the video game to produce their own state­ments, to be interpreted independently. This leaves the final decision about the ideology of the game to the consumer; thus, game studies need an ap­proach that allows the analysis of the ideological content of specific games. It is especially important in the light of more and more games prioritizing player freedom and not providing any clear plot or even victory conditions. Of course, research can still proclaim, and rightfully so, that the specific rules in such games bear traces of certain ideological systems — capitalism or secularism, for example. But individual players could undermine such interpretations both at the level of reading the game as a “text”, and at the level of interactive actions inspired by those readings.

The use of targeted inhibitors has shown promise as an effective approach in cancer therapy. However, targeted therapies based only on one drug, such as 17-allylamino-17-demethoxygeldanamycin (17-AAG), have limited success, partly because cancer cells engage alternate pathways for survival and proliferation. In the present study, we evaluated whether dehydroxymethylepoxyquinomicin (DHMEQ), a nuclear factor ?B (NF-?B) inhibitor, can enhance the antitumor activities of 17-AAG, a 90 kDa heat shock protein (Hsp90) inhibitor, in the anaplastic thyroid cancer cell line KTC2. We examined the effect of combined drug treatment vs single drug treatment on cell survival. Isobologram analysis was performed to distinguish the additive vs synergistic effects of the drug combination. Western blotting was performed to investigate apoptosis markers: caspase 3, poly(ADP-ribose) polymerase-one (PARP-1), B-cell lymphoma-extra large (Bcl-XL), X-linked inhibitor of apoptosis (XIAP) and cellular inhibitor of apoptosis 2 (cIAP-2). Compared to monotherapy, the combined treatment enhanced growth-inhibitory effects in a synergistic manner and strongly potentiated apoptosis. These results demonstrate the first in vitro evidence that a combination of Hsp90 and NF-?B inhibitors is a more effective modality for inhibiting cell proliferation and survival in anaplastic thyroid carcinoma cells than either agent alone, warranting further investigations.

The study examined some aspects that affect the motivation of medical students to study and the formation of a part of professional competencies aimed at assessing the ability to work with patients in practice. The aim of the work was to assess the views of KSMU students about the importance of the educational process, motives that affect the success in obtaining education, professional prospects, career growth. The study was carried out by the method of questioning 68 4th year students and 85 6th year students of the medical and preventive medicine faculty. To study the motivational sphere of the personality, we used the methodology "Motivation for studying at a university". To study the formation of a part of professional competencies (communicative and educational), a questionnaire developed by us was used, aimed at assessing the ability to work with patients in practice. The results of the study showed that students adequately chose their profession and are satisfied with the process of studying at the university. However, senior students have higher rates. Moreover, they have different motivation for learning. The dominance of mastering the profession under the influence of the psychological aspect is becoming stronger among sixth-year students. When analyzing the questionnaire on the degree of professional competence, it was revealed that the outpatient service and district doctors remain in secondary roles, forced to concede laurels and money to high-tech hospitals and narrow-profile specialists, and university students are a product of time. Thus, the teacher of the clinical department has a great responsibility in the formation of professional competencies and strengthening the student's motivation for learning.

A generic algorithm for the membership problem in the semigroups of integer matrices
Authors: Rybalov Alexander N.
Published: December 2020

Generic-case approach to algorithmic problems was suggested by A. Miasnikov, I. Kapovich, P. Schupp and V. Shpilrain in 2003. This approach studies behavior of an algorithm on typical (almost all) inputs and ignores the rest of inputs. In this paper we prove generic decidability of the membership problem and the mortality problem for semigroups of integer matrices of arbitrary order.
Evaluating mean time to security failure based on continuous-time Markov chains
Authors: Magazev A. A. , Melnikova A. S. , Tsyrulnik V. F.
Published: December 2020

In the article, we consider a Markov model of computer attacks, in the framework of which attacks and the system responses are modelled by homogeneous Poisson point processes. We describe a method of solving the corresponding Kolmogorov system of equations by calculating eigenvalues and eigenvectors of some matrix. An important random variable associated with the corresponding Markov chain and called the time to security failure is explored in detail. The comparison of the results obtained and the results of simulation modelling are presented.
Maternal Attitude to a Frequently Ill Child of Preschool Age

Objective: to study the characteristics of the maternal attitude to the often ill child of preschool age. Research methods: Test-questionnaire of parental relationship - ORO (A. Ya. Varga, V. V. Stolin), Analysis of family education - DIA (E. G. Eidemiller and V. V. Yustitskis). The results showed that the maternal attitude has its own specificity in families with often sick children and is manifested in the following features of the maternal attitude to sick children. Mothers who are often ill children often project the same qualities that they themselves consider unacceptable. Mother can manifest hypoprotection in relation to the child, that is, the emotional rejection of the child, the superficial interest in his affairs. At the level of the trend, the tendency of mothers to establish symbiotic relationships with often ill preschool children was revealed. The great practical significance of the study lies in highlighting the direction of the provision of psychological assistance to both the child and, above all, the mother of the often ill child in order to correct her maternal attitude.
Iimitation of Personal and Professional Responsibility under the Terms of the Directives

Published: December 2020

Responsibility is understood as altruistic activity based on awareness of the consequences of one's

activities. The article justifies the forced need to imitate responsibility, when an employee is required to

have activities contrary to his professional conscience and common sense. Contradictions related to different understandings of “good” work (honest, high-quality, socially oriented) by different subjects of labor relations, including the employee and the bearers of policy prescriptions (leadership, colleagues, members of the public etc.) are analyzed. It proposes a model of predicting possible imitations of personal and professional responsibility, based on the reflection of these contradictions. In the case of creative work (science, education, culture etc.), under strong bureaucratic pressure of various policy prescriptions, the ideas of the development of “parallel” science are proposed, when, on the one hand, it is necessary to imitate a certain activity (ostentatious “workholism”), and on the other hand, to find opportunities for real creativity.
Deregulation factors of business communicative norms in modern English drama texts
Authors: Kharkovskaya A. A. , Leonovich L. M.
Published: December 2020

This article aims at the analysis of the linguistic and paralinguistic aspects of business communicative models in the plays by modern English speaking playwrights. The main methods of the undertaken study are those of functional-linguistic and linguosynergetic analysis. Due to the dialogue structure of plays, the examples of personages’ business interactions could be taken as robust empirical material for business discourse studies and observations of the factors which cause deregulation of business communication and its pragmatic norms. During business-related verbal interaction interlocutors follow strict rules and norms of English business discourse to achieve their communicative goals. However, even the most regulated speech behavior could be affected by functional and stylistic fluctuations due to unpredictability of extralinguistic factors. Analysis of extensive empirical material proves that the functional framework of business communicative norms in personages’ speech behavior is regulated by the speaker’s personality, psychology and emotional state, background knowledge as well as multiple elements of the external environment of the discursive functional system. The communicative strategies of drama characters are reflected in their choice of linguistic and paralinguistic methods of pragmatic impact on the interlocutor’s mind.
Training EFL teachers online: how to improve results among adult learners (based on the experiment in Skyeng School)
Authors: Berezin N. S.
Published: December 2020

The paper considers the organizational aspect of EFL teachers’ professional development with a view to improving the educational results of their students. The author suggests a way of determination of the necessity for professional development, a way to organize the process of professional development and the means of measuring the effectiveness of this process. The fundamental didactic principle of the proposed approach is the timely on-the-job professional teacher`s development. At the beginning of the paper, the author discusses the changes that came along with the development of the EdTech market, online tools in education, opening up both new requirements and new opportunities to solve the problems of all participants of the educational process. Among the burning problems of the participants of the educational process are the following ones: the individual educational request of the student, the requirements of companies for the competencies of employees and candidates in the market, the influence on the student's result by the teacher’s training, the automation of teaching aids and tools for their analysis. One of the main demands of our time is, surely, the development of separate competencies, such as: social, emotional and digital activities of a person, the ability to be flexible in relation to circumstances, the ability to learn and relearn. The ecosystem solution of the listed problems is considered by the author as the most effective way, which is designed not to separate, but to unite the efforts that coordinate the goals of each of the participants and satisfy their needs. It is proposed to influence the student's result, formulated by themselves in accordance with the market or individual educational needs, by providing teachers with timely training and support for conducting a good first and subsequent lessons. As the evidence of the effectiveness of the considered approach, the main part of the article views the experiment of the training center team responsible for the training of 10,000+ English teachers at the Skyeng online school. This part provides an exhaustive description of the project, the proposed tools, training formats and metrics to calculate the effectiveness of the experiment; for the purpose of clarity, charts and other visual decryptions are added. The paper ends with a glossary, which will be useful to all experts experimenting in education, but especially for teachers, methodologists and managers of educational programs.
