Published: July 2021

Education is the leading springboard for the formation of an environmentally cultured and educated person who can live and work in today’s rapidly changing society. The environmental crisis and the focus on sustainable development determine the relevance of socio-ecological education in the interests of the Concept of Sustainable Development (1994). The process of professional training of the future professor is based on the Federal State Educational Standard of Pedagogical Education and the professional standard, which defines the universal, general professional, and professional competencies and labor actions of the professor. The lack of special competencies indicates the formation of knowledge, abilities, skills, and experience in the field of socio-ecological education within the framework of general professional and professional competencies. The result of the future professor’s readiness for continuous socio-ecological education of students is determined by the socio-ecological knowledge. The development of socio-ecological knowledge in the conditions of professional training at the university requires the creation of a specific pedagogical system, including forms, methods, technologies, and pedagogical conditions for its development. These conditions include the creation of a socio-eco-oriented educational environment, the integration of formal, non-formal, and informal education, the use of modern digital, information and communication, and educational technologies. The selected components of socio-ecological knowledge: motivational-value, cognitive, activity, and reflexive formed the basis of the experimental study.

Published: July 2021

The article discusses the issue of designing the landscape and architectural environment of eco-spaces for the purpose of eco-education and upbringing. Since the main solution to environmental problems is the education of ecological culture, the formation of a new type of ecological consciousness among the younger generation, the design of eco-sites is the most relevant solution in this area. After analyzing the existing eco-sites and eco-trails, we can draw certain conclusions and identify several factors that are necessary when designing landscape eco-spaces. The creation of an eco-platform on the territory of park zones will attract the attention of the population to the problems of environmental pollution, as well as the education of ecological culture and the popularization of ecological and educational activities among young people. Visitors to the site, aimed at eco-education, will plunge not just into the architectural and landscape area, but into a whole educational camp, where everyone can find a convenient way to get information. The modern, designed space will be able to promote the development of creative and research abilities of children during the summer and winter holidays. The complex should include such areas as: entrance, exhibition, administrative and office premises, recreation area, area of cultural events, master classes, lectures. For the perception of a holistic environment, it is necessary to preserve the unity of the composition and create a thematic planning structure of the eco-space. A prerequisite is that the development of the relationship between the premises and the multi-level space provides for the logical movement of visitors around the ecological site. People who are immersed in the process of observing nature will do this in a constant mode, studying the growth of plants, changes in the weather, and so on.

Authors: Trifonova T.M. , Malyavin D.A.
Published: July 2021

The article deals with the problem of the harmonious development of schoolchildren in the city of Khabarovsk. The key components for the harmonious development of the personality of a modern student are shown theoretically. The survey data of schoolchildren of grades 6-11 on the subject of their satisfaction with the organization of the educational process have been presented. The analysis of the respondents’ answers revealed a complete discrepancy between the real conditions of teaching modern schoolchildren to those components that are necessary for the harmonious development of the child’s personality in the system of lifelong education. In the studied educational institutions of Khabarovsk priority is given mainly to the learning process. The educational process is often implemented in only one direction to the detriment of other areas of education. The results obtained define the problem of determining the causes of such stagnation, as well as the conditions conducive to the development of active, harmoniously developed people.

In this article, we analyze the resilience of older adults and its probable predictors. Among predictors that affect the individual level of a person’s resilience in older age, we consider the participation in different types of activities and personal coping strategies to respond to challenges through the life-course. The article presents the results of a correlation analysis of resilience with the financial, consumer and labor behavior of older adults. We have revealed that the types of financial and consumer behavior, information and communication practices significantly differ for individuals with different resilience levels. Constructive coping with the new conditions and requirements for the well-being allows older adults to maintain a high level of resilience and participation in society. Older people, focused on mastering new skills for a successful life in a changing world, have high indicators of resilience, focus on self-confidence, energy, preventive overcoming of difficulties, have low rates of catastrophic situations.

Sustainable development of tourist destinations is based on the key principles of sustainable development in general taking into consideration the characteristics of tourism as an activity, in particular. In the event that a tourist destination has an island location, this becomes an additional factor imposing even more stringent requirements for sustainable development due to even greater vulnerability of isolated ecological systems. At the same time, the human factor becomes decisive, because the development of a tourist destination depends on how the providers of tourism services comply with the principles of sustainable development. The purpose of our study is to identify the willingness to follow the principles of sustainable development of a tourist destinations among entrepreneurs providing tourism services, using innovative methods of problem-solving learning. During the study, the following methods were used: bibliographic, analytical, in-depth survey method, etc. The methodology implemented for this study was qualitative survey where students reflected on their learning processes. The results show the importance of university students cooperating with actors within tourist destination on both theoretical and practical issues of sustainability to develop the destination. This cooperation enables the most important learning outcomes for both parties on sustainability. Heterogeneity of the group, and methodology of Design Thinking increases the creativity in problem solving.

Market digital platforms and economic inequality
Authors: Sukharev M.V.
Published: July 2021

The article studies the issues associated with the emergence and widespread distribution of such new systems for the market economy as global digital trading platforms, as well as their impact on economic inequality. The paper proposes the systematic analysis of the organization of these platforms, on the basis of which it is concluded that their main effect is associated with a significant reduction in transaction costs (by one or two orders of magnitude) when searching for goods, making transactions and paying for them. Statistics show an increase in economic inequality, though, a priori we could expect a reduction in inequality as a result of small and medium-sized businesses gaining access to global markets.

Published: July 2021

The article substantiates the need to study the conditions for the formation of the middle class. Various approaches to the assessment of the middle class are considered and the author's approach based on factor modeling of balanced personality development is justified. The model clearly allows us to understand the reasons for the extremely low share of the middle Russian class, the lack of coordination of institutional changes with the harmonious development of the individual. This is due to the unevenness of ownership of production elements, the factors of the impossibility of changing the social status for people with higher education and demanded qualifications. Based on the simulated factors of life satisfaction and comfort of living of the population, a sociological survey was carried out, the results of which were processed using economic and mathematical methods and presented in graphic form. The author substantiates the use of the factor model of population quality of life management for the formation of methods and technologies for managing a set of measures that allow influencing the increase in the share of the middle class.

Authors: Savin Gleb
Published: July 2021

The formation of integrated logistics is the economic mainstream today, which can be characterized by rationality, striving for balance, as well as the predominance of “predatory” instincts for the development of economic agents. At the same time, it is has the features of hedonism and subjectivity, and besides, the evolutionary nature of its influence on the socio-economic system is not fully reflected. Today, the trend of its development is formed with the help of socio-technological drivers of the digital economy and information and communication technologies. So, logistics can be useful in the field of rational choice of optimization, which allows not to break away from the realities in theory. Moreover, digital logistics is already able to offer an achievable vision of the future arrangement in the field of management of flow processes in the modern information space, as well as to determine the optimal paths of evolutionary development.

Published: July 2021

The article contains the author’s approach to the formation of indicators of sustainability of management of organizations. The developed approach holds the emphasis placed on its traditional understanding, transformed into the modern entrepreneurial era, based on the environment of the functioning of business processes of organizations’ activities, composed of controlled (endogenous) and uncontrolled (exogenous) factors that form their management costs and determine total costs and efficiency, on which the financial benefit in the future period depends. The study considers selected resultant and factorial indicators of the sustainability of management of organizations: management efficiency and cost, changes in the dynamics of results and costs under the action of the specified qualitative and quantitative parameters of management activities. The basis for constructing dependencies between resulting and factorial indicators of the stability of management of organizations is the unity of differentiated by types of additive, multiplicative and multiple interactions, included in the selected combination of intermediate (factor) valueswith final (resulting) values. The integrity of all dependencies, forming a common system of the considered indicators will provide organizations with an accurate assessment of the analyzed final values and a gradation pursuant to the degree of value significancein the intermediate group and objective measures to optimize their management stability. The material may be beneficial for entrepreneurs operating under the current economic mechanism, regardless of spheres and industries, education and science specialists, students in management areas.
Management system of a sustainable organization: attributes and factors
Authors: Dolgaya Angelina , Kovbasyuk Olga
Published: July 2021

The purpose of the study is to identify the main features of the management system of a sustainable organization and the driving forces of its development. The results of the study are used to create a conceptual model of the management system of a sustainable organization. To achieve this goal, the authors analyzed the existing principles, approaches and management models of sustainable organizations both in the form of cases of successful companies and in a generalized form. The analysis was carried out according to the authors’ structure of the architectonics of the organization management system. The features of the management system of a sustainable business organization were discovered, among which the key place, as a factor of its development, is the set of values of the leader. This specific set of values is called “sustainability”, and it determines the appropriate functioning of other elements of the system, such as organizational culture, performance indicators, and internal standards. The most significant sign of the influence of the set of values “sustainability” on the management system are investment decisions, and in particular, the choice of production technologies in the development of the company. The study confirmed the need for a comprehensive approach to assessing the sustainability of business organizations. The necessity of forming a set of values of leaders and owners of companies as the main factor in the development of sustainable business ecosystems is also revealed.
Econometric approach to modeling the global partnership between the Russian federation and the republic of Belarus in the manufacturing industry
Authors: Petrov Mikhail , Serkov Leonid , Kozhov Konstantin
Published: July 2021

The working hypothesis of the study is the postulate that the implementation of the global partnership of the Russian Federation and the Republic of Belarus should take place at the level of interregional interactions. The paper proposes the methodological approach and tools for assessing possible interregional interactions between the constituent entities of the Russian Federation and the Republic of Belarus in the manufacturing industry, as well as investigates the factors influencing this interaction. Data from the official statistical websites of Russia and Belarus for 84 subjects of the Russian Federation and the Republic of Belarus were used to calculate the studied indicators. At the first stage, the spatial distribution of the volume of output in the manufacturing sector of the regions of the Russian Federation and the Republic of Belarus is analyzed in order to assess the possibilities of interaction between these regions in this sector of the economy. When modeling, the Republic of Belarus is considered as a separate region within the Union State. A positive autocorrelation was established between the subjects of the Russian Federation and the Republic of Belarus using Moran’s indices. At the second stage, the influence of economic, infrastructural and institutional factors on the indicator characterizing the degree of possible interaction of the regions of the Russian Federation with the Republic of Belarus in the manufacturing industry was studied. The influence of economic, infrastructural, and institutional factors on this indicator under study was studied using Beta regression. The use of this approach makes it possible to substantiate the priority areas of economic development of territories within the Union State, in particular, to search for centers of attraction of resources and spheres of their influence on the territory. The findings of this paper can be used in the preparation of strategies, programs, and schemes for the placement and development of industries taking into account the potential of a new level of integration of the economies of Russia and Belarus.

The article examines the main types and aspects of business ecosystems, traces the stages of their formation, systematizes and reveals the features and basic principles of partnerships, based on which, within such systems, organizations may ensure their effective and sustainable development.
Existence of traveling wave solutions for the Diffusion Poisson Coupled Model: a computer-assisted proof
Authors: Breden Maxime , Chainais-Hillairet Claire , Zurek Antoine
Published: July 2021

The Diffusion Poisson Coupled Model describes the evolution of a dense oxide layer appearing at the surface of carbon steel canisters in contact with a claystone formation. This model is a one dimensional free boundary problem involving drift-diffusion equations on the density of species (electrons, ferric cations and oxygen vacancies), coupled with a Poisson equation on the electrostatic potential and with moving boundary equations, which describe the evolution of the position of each unknown interfaces of the spatial domain. Numerical simulations suggest the existence of traveling wave solutions for this model. These solutions are defined by stationary profiles on a fixed size domain with interfaces moving both at the same velocity. In this paper, we present and apply a computer-assisted method in order to prove the existence of these traveling wave solutions. We also establish a precise and certified description of the solutions.
Research on the electric field intensity distribution of high-voltage cable terminal improved by non-linear material
Authors: Li Guowei , Wang Yong , Xu Xuexia
Published: July 2021

The electric field distortion caused by the high voltage current environment in the cable terminal will greatly increase the failure probability and reduce the operation safety; therefore, it is necessary to ensure the uniform distribution of the electric field in the terminal. This paper briefly introduced the high-voltage cable terminal and non-linear materials. The traditional silicone rubber and the silicone rubber added with nano-SiO2 were prepared. The electrical conductivity of the two silicone rubbers was tested, and the electric field of the cable terminal was simulated. The results demonstrated that the nano-SiO2 improved silicone rubber had a higher non-linear conductivity and was less affected by temperature. The calculation results of the simulation model also showed that the distribution of the internal field strength was more uniform, and the maximum field strength on the reinforced insulation was smaller after the improved silicone rubber was used as the reinforced insulation.

Fast magnetic reconnection induced by resistivity gradients in 2D magnetohydrodynamics
Authors: Lin Shan-Chang , Liu Yi-Hsin , Li Xiaocan
Published: July 2021

Using two-dimensional (2D) magnetohydrodynamics simulations, we show that Petschek-type magnetic reconnection can be induced using a simple resistivity gradient in the reconnection outflow direction, revealing the key ingredient of steady fast reconnection in the collisional limit. We find that the diffusion region self-adjusts its half-length to fit the given gradient scale of resistivity. The induced reconnection x-line and flow stagnation point always reside within the resistivity transition region closer to the higher resistivity end. The opening of one exhaust by this resistivity gradient will lead to the opening of the other exhaust located on the other side of the x-line, within the region of uniform resistivity. Potential applications of this setup to reconnection-based thrusters and solar spicules are discussed. In a separate set of numerical experiments, we explore the maximum plausible reconnection rate using a large and spatially localized resistivity right at the x-line. Interestingly, the resulting current density at the x-line drops significantly so that the normalized reconnection rate remains bounded by the value ≃0.2, consistent with the theoretical prediction.

Published: July 2021

We report on reversible and continuously deformable soft micro-resonators and the control of their resonance split and directional emission. Assisted by computerized holographic-tweezers, functioning as an optical deformer of our device, we gradually deform the shape and change the functionality of a droplet whispering-gallery cavity. For example, we continuously deform hexagonal cavities to rectangular ones and demonstrate switching to directionally emitting mode-of-operation, or splitting a resonant mode to a 10-GHz separated doublet. A continuous trend of improving spatial light modulators and tweezers suggests that our method is scalable and can control the shape and functionality of many individual devices. We also demonstrate optional solidification, proving the feasibility of transformer-enabled applications, including in printing optical circuits and multiwavelength optical networks.
A kinetic model of friction in strongly coupled strongly magnetized plasmas
Authors: Jose Louis , Baalrud Scott D.
Published: July 2021

Plasmas that are strongly magnetized in the sense that the gyrofrequency exceeds the plasma frequency exhibit novel transport properties that are not well understood. As a representative example, we compute the friction force acting on a massive test charge moving through a strongly coupled and strongly magnetized one-component plasma using a generalized Boltzmann kinetic theory. Recent works studying the weakly coupled regime have shown that strong magnetization leads to a transverse component of the friction force that is perpendicular to both the Lorentz force and velocity of the test charge, in addition to the stopping power component aligned antiparallel to the velocity. Recent molecular dynamics simulations have also shown that strong Coulomb coupling in addition to strong magnetization gives rise to a third component of the friction force in the direction of the Lorentz force. Here, we show that the generalized Boltzmann kinetic theory captures these effects and generally agrees well with the molecular dynamics simulations over a broad range of Coulomb coupling and magnetization strength regimes. The theory is also used to show that the “gyro” component of the friction in the direction of the Lorentz force arises due to asymmetries associated with gyromotion during short-range collisions. Computing the average motion of the test charge through the background plasma, the transverse force is found to strongly influence the trajectory by changing the gyroradius and the gyrofriction force is found to slightly change the gyrofrequency of the test charge resulting in a phase shift.
Measurement of the impedance for a hybrid X-pinch load
Authors: Wang Liangping , Sun Tieping , Qiu Aici , Zhang Jinhai
Published: July 2021

For a hybrid X-pinch load assembled in parallel with the return-current rods, the impedance of the hybrid X-pinch load is important for current division between the load and the current rods. In this paper, the experimental results of the investigation of the impedance of a hybrid X-pinch load on the Qiangguang facility (1.5 MA, 100 ns) were reported. The current of the X-pinch load was measured using a serial nickel foil resistor, and the voltage was measured using a two-stage resistive divider. The inductance of the X-pinch load was obtained by comparing the differential signal of the current with the voltage waveform, and it is about 4.7 nH, which is nearly equal to the calculated total inductance of the metal wire and the two X-pinch electrodes. The resistance of the X-pinch was determined by subtracting a part of the inductance from the measured voltage, and the following results were obtained. At the start of the current, the resistance of the X-pinch increases quickly from the metallic resistance of 0.16 Ω at room temperature for a 2-mm-length 30-μm-diameter Mo wire to 0.8 Ω in about 10 ns, and then, it falls fast to nearly zero, which suggests that the electrically exploding phase of the metal wire ends and the high conductive plasma is formed. As the current continues to flow through the Mo wire, the resistance increases once again from nearly zero to about 0.4 Ω at the moment when the X-pinch begins to burst x-ray radiation, which reflected that the micro-pinch dynamical process occurs and a hot and tight plasma zone is formed. Assuming that the tight plasma zone is 300 μm long with a 10 µm diameter and the temperature of the plasma is ∼1 keV, we can obtain that the resistance of the tight X-pinch spot is about 0.6 Ω, which is close to the value of 0.4 Ω obtained in the experiments.

Two-phase gas–liquid stratified flow is characterized by a structure in which the gas and liquid phases are separated from each other by a continuous interface. Adequately understanding its flow mechanism and heat transfer is important for analyzing two-phase stratified flow. This paper develops a mechanistic model of flow and heat transfer in turbulent–laminar/turbulent two-phase stratified flow in horizontal and slightly inclined pipes. First, a hydrodynamic model of two-phase stratified flow is developed by using the concept of two-fluid model. Second, a mechanistic model of heat transfer is derived based on the hydrodynamic model. The overall heat transfer coefficient is integrated by using the coefficients of local heat transfer of the liquid film and the gas core. Third, the effect of such flow geometries and parameters as the superficial Reynolds numbers for liquid and superficial gas, void fraction, pressure drop, and inclination angle of the pipe on heat transfer in two-phase stratified flow is comprehensively investigated. Finally, the relationships between the two-phase heat transfer multiplier and the overall void fraction and pressure drop multipliers are quantified. A simple correlation of the heat transfer multiplier for two-phase stratified flow is developed by using the void fraction as the input parameter serving as a quick but rough prediction of the heat transfer multiplier in two-phase stratified flow.

Context Livestock feed costs have a higher impact on the profitability of beef production systems and are directly related to feed efficiency. However, these traits are hard and have high costs to measure, reducing the availability of phenotypic records and reliability of genetic evaluations. Thus, the use of genomic information can increase the robustness of genetic studies that address them. Aims The aim of the present study was to estimate genetic parameters for feed efficiency, growth, reproductive and carcass traits in Nelore cattle and the correlated response among them, using genomic information. Methods Residual feed intake (RFI), dry-matter intake, feed conversion ratio, feed efficiency (FE), residual average daily gain (RG), residual feed intake and average daily gain (RIG), birthweight, weight at 120, 240, 365 and 450 days of age, scrotal circumference at 365 and 450 days of age, rib-eye area, backfat thickness and rump fat thickness were evaluated. The genetic parameters were estimated using the single-step genomic best linear unbiased prediction approach. Key results The FE-related traits showed low to moderate heritability ranging from 0.07 to 0.23. Feed efficiency-related traits showed low genetic correlations with reproductive (–0.24 to 0.27), carcass (–0.17 to 0.27) and growth (–0.19 to 0.24) traits, except for growth with dry-matter intake (0.32–0.56) and weight at 365 days of age with FE (–0.40). Conclusions The selection to improve growth, reproductive and carcass traits would not change RFI, RG and RIG. The choice of the most adequate selection criterion depends on the production system, that is, RFI might be used for low-input beef cattle systems, and RIG would be used for more intensive and without-any-dietary-restrictions beef cattle systems. Implications The estimates of heritability and genetic correlations suggest that genetic selection for feed efficiency using RFI, RG and RIG in Nellore cattle leads to higher genetic gain than does that using FE and feed conversion ratio without affecting other profitability traits.

Significance

SNF1-related protein kinase 2s (SnRK2s) are central regulators in abscisic acid (ABA) signaling and stress responses in plants. However, SnRK2 substrates are largely unknown. Here, we identified
Arabidopsis
group C Raf-like kinases Raf36 and Raf22 as SnRK2 substrates. Reverse genetic analyses showed that Raf36 and Raf22 negatively regulate ABA signaling. Under optimal growth conditions, Raf36 accumulates in the cell and phosphorylates substrates to suppress ABA responses. Conversely, under abiotic stress conditions, ABA-activated SnRK2s phosphorylate Raf36 and promote Raf36 degradation, leading to stronger ABA responses. Taken together, this study provides insight into molecular and physiological functions of group C Raf kinases in ABA signaling.
