Fast-growth firms and successful environmental entrepreneurs in emerging countries
Authors: Mirvahedi Saeed , Morrish Sussie C. , Pletnev Dmitri
Published: May 2021

Growth is a broad area and many aspect of growth is under research especially in smaller and entrepreneurial firms. Many research show that growth and fast growth happens randomly and is not a continuous phenomenon. In this study, we investigate how successful entrepreneurs grow their firms. The investigation involved ten fast-growth firm cases in Iran -as an emerging economy- in different industries. The research is qualitative and data gathered through semi structured in-depth interviews. After coding, all interviews are mapped. By using Decision Explorer® all causal maps are analyzed. Analysis show that fast growth is a direct outcome of entrepreneurial marketing (EM) practices and indirectly influenced by serendipity. Serendipity is an element observed in many firms that generally occurs at the initial phase of firm formation and could bring great opportunities but indirectly associated with fast-growth. However, serendipity itself is not important but the ability to recognize and exploit opportunity is a crucial activity that entrepreneurs are really great at it. The ability of entrepreneurs to exploit serendipitous opportunities and use entrepreneurial marketing practices in terms of innovative products and activities/process lead to fast growth. Other elements, such as network, innovation, and perseverance, could either directly or indirectly influence growth.
Instability of socio-economic and sustainable development of Ural regions
Authors: Barkhatov Victor
Published: May 2021

Problems of development stability of regional economies are of particular importance in current conditions. The article presents the analysis of the sustainability of the development of Russian regions included in one of the most industrially developed federal districts - the Ural. The study used data from Rosstat for 2001-2019. The tendencies of the instability of indicators of socio-economic development of regions are revealed: gross regional product, investments in fixed assets, industrial production, and consumer prices. It has been established that the dynamics of the growth rates of these indicators are volatile. At the same time, all trends demonstrate a reasonably rapid recovery after the external shocks of 2008 and 2014. These indicators’ volatility was assessed using the variation coefficient in three different periods: 2001-2008, 2010-2014, and 2015-2019. The conclusion is made about the high instability of regional socio-economic development, while the level of instability in regions with a lower level of development turned out to be higher than in more developed ones. Particular attention is paid to trends in the level of instability, and it is noted that over time, less developed regions increase instability at a faster pace.
Delta-result in the production structure of a sustainable enterprise
Authors: Nevelev Anatoly , Kamaletdinova Alfiya
Published: May 2021

The sustainability of an industrial region is rooted in the sustainability of the production process itself. Industrial production is strictly focused on the product, which plays a crucial role in production structure. The instability of production is associated with the delta-result, which should be the subject of scientific research. The delta rule is the difference between the result and the product. It categorically grasps the source of instability of the region’s production and industrial development as a whole. The interaction of material production and science, as an ideal production, provides the most optimal conditions for managing the complete result of an industrial region’s life activity. The article presents the rationale for using the delta-result assessment methodology in the analysis of sustainable development of the region, including the processes of goal-setting and sustainable development. The work results can be used to improve the efficiency of management of both industrial enterprises and institutions carrying out sectoral or territorial regulation.

Published: May 2021

In Economic operators Finance theory they have described many models and approaches to assessing the criteria of a firm’s ability to be liable for its debts to the contractors. Despite the fact that the issue of submitting to payment discipline is extremely important nowadays, in practice these approaches and models are used in checking the potential paying capacity either of the contractor or of one’s own firm. The main issue consists in the fact that many rather dogmatic criteria used in the process actually do not lead to accurate results, thus resulting in quite the opposite conclusions due to their abstractedness, as well as to ‘uncertainty’ of the input data. The aim of the paper is to show the ways of calculating one of the key and the most currently used criterion of paying capacity – the absolute liquidity ratio. The paper considers advantages and disadvantages of the already existing approaches, analyzes the results of a negligent approach to payment capacity analysis by the example of calculating the criterion in question. The theoretical background is offered for practical approbation of the viability of the method offered in the paper. The practical part offers a set of successive calculations, shows the algorithm of the calculations according to the method in question.
Investment in ecology
Authors: Semenova Galina
Published: May 2021

Investing money in environmental protection measures is an investment project. The ecological problem is one of the global problems of our time. Disposal of household waste and their pollution of the environment is currently one of the most serious environmental problems in Russia. Human waste products also significantly affect the pollution of water bodies, since water that is used in cities for the needs of the population from the sewage system often enters directly into open water bodies, bypassing the system of treatment facilities, the quality of which leaves much to be desired: most of them almost cannot cope with their functions due to outdated and deteriorated equipment. In Russia, the national project “Ecology” has been adopted, since the need for the introduction of new technologies that do not harm the environment has long been acute. The subject of the study is the investment of enterprises and organizations in environmental innovations for the preservation of natural resources. The purpose of the study is the necessity and significance of investments in high-tech projects to improve the environmental situation and reduce emissions of pollutants into the air. Methodology. The financial support of the new national project “Ecology” has been studied. The companies that successfully implement the latest technologies in their production, focused on reducing the harm caused to the environment, thereby attracting investments in their projects, are highlighted. Results. Enterprises will be able to attract investments for the development of their own production only if they are attractive to investors, for whom such aspects of work as the introduction of modern technologies, taking into account the minimization of harm to the environment, are extremely important.

Annotation.

Spiritual and moral values and motives are historically the basis of the mental matrix of the Russian citizen, determining the development and acting as a psychological coping mechanism in a crisis. In the modern world, it is spiritual values and motives that are being transformed. Mental protection of a personality based on the integrity of primal archetypes of the collective unconscious, creating mental traits and identity is interrupted, which leads to destructive changes, specifically, deprivation, alienation, deviance. In this regard, the purpose of the article is to identify the features of the transformation of spiritual and moral values of modern Russians. In the course of four sociological studies in 2007, 2009, 2010, 2019 in the regions of Russia, the values of schoolchildren (15-17 years), students (17-22 years), working youth (23-29 years) were studied. The research was based on personal, activity oriented, systemic and subjective approaches. It resulted in the consideration of the dynamics of personal values’ changes from 2007 to 2019, revealing the integrity of basic, spiritual, and moral values, which are fundamental for the personality formation of a Russian living in a particular historical and geographical environment.

Published: May 2021

The article presents the results of studying the personal maturity of adolescents aged 13-17 (n=1078) who are infantilized in intergenerational relationships (on the model of relations with parents and teachers). Empirical data were collected with the use of the Self-Assessment Scale of Personal Maturity, as well as the modified Dembo-Rubinstein Self-Assessment Diagnostic Method, which measured the actual self-assessment of adolescents’ adulthood, as well as reflected assessments of their own adulthood from the parents’ and teachers’ positions. Infantilization in intergenerational relationships was assessed by comparing the self-assessment of adulthood and the reflected assessments of parents and teachers. The results show that the relationships between adolescents, on the one hand, and parents and teachers, on the other hand, are characterized by a tendency to infantilization. Obvious infantilization is found in about 10 % of cases. Infantilization in intergenerational relationships affects, first of all, the regulatory maturity of adolescents, and its influence differs depending on who is the subject of infantilization: in the case of infantilization by parents, the regulatory maturity of adolescents decreases as they grow up, while in the case of infantilization by teachers it increases. In general, infantilization in relations with parents has more intense negative impact on the formation of personal maturity in adolescence, in comparison with infantilization on the part of teachers.

Speed Reading as a Psychological Problem
Authors: Bilaya Angelina
Published: May 2021

The demand for innovative learning methods is dictated not only by the speed of changes and updates of the knowledge system, but also by the enormous growth of data. The need to navigate the vast and dynamically changing field of information requires more sophisticated skills of working with it. Reading is still one of the main ways of gaining knowledge. Improving the reading skill allows not only to work with text information faster and more efficiently, but also to qualitatively change the intellectual abilities of a person by means of speed reading. This study presents a theoretical overview of the modern scientific understanding of speed reading, and examines the psychological aspects (cognitive, motivational-meaning-building) that have an impact on the effectiveness of speed reading learning process. Our aim is to develop an appropriate training program, which will take into account not only the capabilities and limitations of the visual and cognitive systems, but also motivational-meaning-building component, which largely determines the student’s involvement in the lesson and the level of results achieved. The implementation of this program in the educational process will allow to optimize the time and effort necessary to acquire a certain amount of educational knowledge, as well as to increase the motivation and personal interest of the individual in the process of education and self-education.

The history of studying autoaggressive behavior model and cognitive rigidity is quite extensive and diverse. Nevertheless, the relevance of studying the problem of autoaggression among adolescents has increased significantly in recent decades. Self-harming and self-destructive behavior has become a fashion trend among the younger generation. The aim of the research is studying of features cognitive rigidity in adolescence with a tendency to autoregressive behavior model. the study involved 65 students of secondary school aged 14-15 years (M=14,4; SD=0,8). The following methods were used: «Tendencies to deviant behavior» (A.N. Orel), The Stroop Color and Word Test, besides statistical techniques (descriptive statistics, Mann Whitney U test, Spearman rank correlation coefficient). As the result of the research it was proved that adolescents who are prone to autoaggressive behavior model, the level of cognitive rigidity is higher, in comparison with adolescents who are not inclined to self-destructive behavior. There was also discovered a positive relationship between the degree of propensity for autoaggressive behavior model and the level of cognitive rigidity. The prospects of the research cover the study of the personal characteristics of children and parents, the styles of family education that contribute to the formation and development of cognitive rigidity, the tendency to auto-aggressive behavior. The results of the research can be used in the organization of psychological and pedagogical support of adolescents and their families.
Distance Learning Challenges in Translation Teaching: Mediation Competence Development
Authors: Enbaeva Lyudmila , Plastinina Nina
Published: May 2021

In recent years the COVID pandemic has influenced education significantly. The pace of digital transformation is very fast and requires a change of mindset. Translators or cross-language mediators have to work at the focal point of various information transfer processes. We think that a digital mindset of a future translator can be created by re-contextualising classroom communication reality with online teaching tools that will ensure synchronous and asynchronous studies. The challenges of online resources variety can be responded to by classifying them according to L2 communicative competence and translation competence structural components. Thus the choice of sources can be narrowed down according to specific teaching objectives. The research proposes a classification of online resources for mediation competence development which is a communicative competence component according to CEFR. Classification categories include online teaching tools that can help develop (1) skills of mediating concepts, texts, communication; (2) strategies of explaining new concepts and strategies of text simplification. The classification is used to work out a few sample activities for an L2 course within translation curriculum. It is assumed that the classification and sample activities will help teachers be more flexible facing distance learning challenges in translation teaching.

Published: May 2021

The transition of the Russian education system in the context of the Covid-19 pandemic to online platforms marked the emergence of new practices of interpersonal communication in the teacher-student relationship system. The article deals with deviant manifestations in the online space of communications. The analysis is based on the study of semantic deviations constructed by young people in the process of communication in a changing reality. The starting point of deviations is considered as a departure from the approved norms of communication in educational system, which leads to such phenomena as trolling, gaming, etc. The influence of virtualization of education on the rethinking of the norms and practices of communication by young people is considered, and the educational space itself, due to its greater openness, becomes a platform for the implementation of these deviant practices. Analysis of the data obtained during sociological research shows the nature of the differentiation of meanings in the field of online communication of young people, which is reflected in the education system.
Environmental sustainability and economic development in Russian regions: spatial analysis
Authors: Suvorova Arina
Published: May 2021

Environmental degradation and increasing risks to regional eco-systems seriously impede the progress towards sustainable development goals. This study is aimed at investigating the spatial aspect of this problem by focusing on the case of Russia, in particular the environmental aspects of the country's spatial organization. Methodologically, the study relies on spatial analysis methods (spatial modelling and mapping) and the official statistical data. As a result, we have identified heavily polluted locations that jeopardize sustainable development efforts on the national level: as these locations are situated in close proximity to each other and share a strong spatial correlation, their combined impact far exceeds that of isolated territories. It was found that Siberia is the largest zone of concentration of air pollution hotspots, where high levels of air pollution are not compensated for by these regions’ outstanding economic performance. Our findings have shown that the patterns of the country's economic and environmental spatial organization do not always coincide. In other words, the regions with booming economies are not always the same regions whose manufacturing sector puts the heaviest pressure on the environment. This can point to the fact that the link between economic activities and environmental pressures is now weakening.
Food safety of bottled water
Authors: Shapsugova Marietta
Published: May 2021

Drinking water is a strategically important natural resource. At the same time, its resource is unevenly distributed over the territory of Russia. One way to redistribute drinking water resources is to bottle and then deliver it to scarce regions. The study’s objectives are to identify gaps in the system of drinking water resource management in Russia. Particular attention is paid to the management of the quality of bottled water. The study showed that despite the strategic importance of drinking water for citizens' health, its quality is not managed at the systemic level. Bottled water is food, and, accordingly, its quality should be standardized for food safety. However, quality regulation is carried out non-systemically and fragmentarily. The identified problems also include the problem of identifying waters and the fight against counterfeit products. The methods of analysis and synthesis, induction and deduction, comparative method, statistical data were used.
Harmonization of improvement of legal and technical regulation of underground space development in Russian cities
Authors: Belyaev Valery
Published: May 2021

The features of legal and technical regulation are considered and the main shortcomings of these systems of public administration are identified. It is shown that they hinder the effective development of the underground space of Russian cities as a promising area of urban development. A related analysis of the results of the author's monitoring of regulatory documents in the field of integrated urban development of underground space, as well as the interim results of the legal research initiated by him, aimed at eliminating defects in federal legislation, is presented. In the context of legal regulation and trends in its development, a new Set of Rules (SR 473) concerning «underground urban planning»is analyzed in detail. The conclusion is made about the systemic shortcomings of this document, which are based on the subjective factor of the manifested «legal nihilism» in combination with the objective deficit and imperfection of the legislative sphere. Proposals are given for the harmonization of amendments and additions to SR 473 and other documents on standardization, depending on the nature and timing of the adoption of legislative initiatives. The topics discussed are of interest not only because of their novelty, but also because of the reality and prospects of the proposed administrative steps that can give impetus to spatial development on the model of a sustainable, viable and compact city.
Unconventional technology for sealing and P&A of wells for prevention of global environmental disasters
Authors: Zakirov Sumbat , Klimov Dmitry , Zakirov Ernest , Indrupskiy Ilya , Anikeev Daniil
Published: May 2021

Many, if not all of the oil and gas fields under development, have leaking wells. There are a lot of so-called abandoned, ownerless wells. Subsoil users, by one way or another, make efforts to eliminate leakage in such wells. At the same time there are no universal and reliable techniques. The problem of well leakage is seriously increasing when wells are decommissioned (plugged and abandoned, P&A), and even more so when the development of the field is finished. The techniques of plugging and abandonment do not guarantee the integrity of the abandoned wells for centuries. Obviously, then the abandoned field would become the object of a local ecological catastrophe. As the development of all oil and gas fields is completed, the Earth will enter the era of the Global Environmental Disasters. In this article authors propose innovative techniques and technical solutions for sealing procedures and plugging and abandonment operations on wells.

Information model of the construction process in space and time
Authors: Kabanov Vadim
Published: May 2021

BIM 3D technologies are traditionally used in the design of construction projects. The prospect of turning BIM 3D into BIM 5D is associated with the need to build information models of the construction process that are able to accurately determine the coordinates of construction and installation work at any time. The purpose of this work is to build an information model in space and time. The paper substantiates the sources of initial quantitative information. A BIM 3D model of a object of construction is a source of information for determining the coordinates (position in space) of the construction process. To calculate the speed of construction, it is proposed to use information about construction resources using national codes. A mathematical apparatus is proposed that can integrate the construction speed value into coordinates using BIM 3D technologies. A flowchart for software product development is proposed. The information model of the building process in space is represented as a vector. The coordinates of the beginning of a vector can always be represented as: X = 0, Y = 0, Z = 0, and the coordinates of the end of this vector are: X, Y, Z. Moving along the vector is described depending on the speed of build.

Authors: Dmitry Pirko , Lia Mayilyan , Ivan Triputa , Leonid Zelentsov
Published: May 2021

The paper discusses the issues of creating a single information space for all participants in the investment and construction project, from the investor to the equipment manufacturers. The analysis of the existing information technologies used in the ICP management made it possible to distinguish four main classification groups. Of particular interest are the so-called integrator systems focused on combining the solution of tasks of certain functional areas of ICP management on one digital platform. Integrator systems, with all their merits, are a set of local information technologies and specialized software performing the functions of exchanging information between them using agreed protocols. At the same time, the main issue that was and remains on the agenda in the field of digitalization of the ICP management system is not being resolved - the creation of an information base that suits both designers and builders in terms of completeness and detail. At the Don State Technical University (DSTU), work is underway to create an intelligent ICP management system, which will ensure the integration of all stages of ICP management by creating an information base at the design stage in the BIM process that allows solving all organizational and technological problems both at the stages of COP, WPP and during operational management of the erection of construction facilities.
Organizational and technological solutions during the production facade works
Authors: Fahratov Muhammad , Ibrahim Ibrahim F.
Published: May 2021

The article deals with the organizational and technological features of construction. Currently, based on foreign and domestic experience, a significant number of regulatory and methodological documents have been developed for the use of facade systems, but these works do not fully disclose organizational and technological issues and contain only general recommendations for the production of work. In particular, the existing recommendations for the installation of facade systems, for the most part, describe the constructive solutions of facade systems, technological issues related directly to the installation of the facade system, while not disclosing in sufficient detail the organization of the construction site, the issues of choosing the necessary means of paving, the issues of standardizing the labor intensity of work, issues of quantitative and qualitative selection of the composition of workers for the production of work. The organization of construction production for the installation of hinged facade systems with an air gap during the construction of buildings is associated with coordination with general construction works. Often, construction management projects developed at the design stage are adjusted taking into account the current conditions. These changes can occur both before the start of work and during the production of work. The introduction of organizational and technological changes in the production process of work can lead to a significant decrease in technical and economic indicators. In this regard, it is relevant to resolve the issues of assessment and selection of effective organizational and technological solutions for the device of facade systems.

The problem of reorganization, as many types of rearrangement in the dyad ‘man-equipment’ (‘operator-equipment’ in transport; ‘worker-equipment’ in mechanical engineering; ‘tenant-building’ in construction and in housing and communal services), is constantly relevant in a developing society. Modeling of ways and forms of solving this problem, the study of different types of reorganization in the dyad ‘man-equipment’, rationing their characteristics and identifying rational areas of their application in the construction industry of our country has been going on since the first half of the 20th century. Scientific studies of the reorganization problem, the proposed functioning models of each of the types of construction reorganization, formation and improvement of regulatory documents of construction production provide effective activities of construction organizations and a necessary level of quality of processes and results of construction production. At the beginning of the 20th century, the main type of construction reorganization was ‘repair’, which by the middle of the century was divided into three distinguishable categories: repair as such, reconstruction and restoration. Each of these categories has individual properties, characteristics and a range of functioning. The basis for this division was social need. At the end of the 20th century, social phenomena of Russian reality again required a revision of the categories of construction reorganization, therefore, construction science proposed innovative types of construction reorganization (renovation, reversal, recomposition, retreatment, etc.). Each type was a response to a new manifestation of social requirements, all types were equally relevant. Only in the second decade of the 21st century, the urban planning and building production reacted to these achievements of the national building science and chose renovation as a basic type of innovative building. The article discusses a renovation model (П-graph of innovative types of construction reorganization), which allows analysis (downscaling, disintegration) and synthesis (enlargement, integration) of concepts, levels and results of construction reorganization processes.

Authors: Gaidukov Pavel , Pugach Evgeniy
Published: May 2021

The article considers existing and promising systems for the construction of slabs in low-rise buildings using stay in place (SIP) formwork. The main conditions for using these formwork systems are described and the disadvantages of existing structures are highlighted. Using the example of previously patented inventions, various trends in the development of formwork systems are revealed. The article deals with precast concrete structures of fixed formwork, modular structures of fixed formwork, various types of connections. Variants of fixed formwork with different types of installation and delivery of concrete mix, made of different materials and shapes are considered. The main individual features of each type of invention are highlighted, on the basis of which assumptions are made for the development of these systems. Based on the results of the analysis, the article offers technical requirements and a brief description of a promising formwork system for the construction of floors of low-rise buildings in cramped conditions.

Authors: Galiev Ilyas , Ibragimov Ruslan
Published: May 2021

Since 2010, there has been a growing trend in the market for mini-excavators from various manufacturers. The range of manufactured equipment is increasing, as well as the technological capabilities of construction equipment are growing. At the same time, in the modern standards of Russia are no figures on the complexity of soil excavation with this type of technology.

The article shows the timing of soil excavation using the example of a mini-excavator with a bucket volume of 0.03-0.04 m3. The object of the study is the amount of time the mini-excavator works on II group of soils. The timekeeping method is used to determine the operating time of a mini-excavator with a bucket volume of 0.03 and 0.04 m3. It is experimentally obtained that the norm of time for operation of a mini-excavator with a bucket volume of 0.03m3 is 5.82 mach *hours, and for a bucket volume of 0.04 m3 is 5.37 mach*hour.

At the present time, the issues of combating environmental pollution are especially acute in the world. At various scientific and public platforms, the sources of the negative impact on the environment and ways to restore the ecosystem are discussed. The purpose of this article is to consider one of the main sources of environmental pollution - construction waste. Having studied a number of works on this topic and summarizing the results obtained, the authors give a detailed description of environmentally hazardous construction waste. At the same time, the authors propose a solution to this problem, which consists in the recycling of waste, that is, in the reuse of unnecessary things for the purpose of subsequent use as raw materials, energy, materials and consumer products. The authors argue that recycling waste can be safe and profitable, with great returns. Thus, the recycling of environmentally hazardous, in this particular case, construction waste will contribute not only to solving environmental issues, but also to improve the economic situation of the state.
