ABSTRACT
We study the decay phase of solar flares in several spectral bands using a method based on that successfully applied to white light flares observed on an M4 dwarf. We selected and processed ...102 events detected in the Sun-as-a-star flux obtained with SDO/AIA images in the 1600 and 304 Å channels and 54 events detected in the 1700 Å channel. The main criterion for the selection of time profiles was a slow, continuous flux decay without significant new bursts. The obtained averaged time profiles were fitted with analytical templates, using different time intervals, that consisted of a combination of two independent exponents or a broken power law. The average flare profile observed in the 1700 Å channel decayed more slowly than the average flare profile observed on the M4 dwarf. As the 1700 Å emission is associated with a similar temperature to that usually ascribed to M dwarf flares, this implies that the M dwarf flare emission comes from a more dense layer than solar flare emission in the 1700 Å band. The cooling processes in solar flares were best described by the two exponents model, fitted over the intervals t1 = 0, 0.5t1/2 and t2 = 3, 10t1/2, where t1/2 is time taken for the profile to decay to half the maximum value. The broken power-law model provided a good fit to the first decay phase, as it was able to account for the impact of chromospheric plasma evaporation, but it did not successfully fit the second decay phase.
Purpose
The purpose of this paper is to specify the conceptual foundations of educational cooperation of universities and companies of Industry 4.0 for maximizing its efficiency.
...Design/methodology/approach
For determining the efficiency of educational cooperation of universities and companies of Industry 4.0 in modern Russia, the authors use the information and analytical materials on the results of monitoring of effectiveness of the activities of educational organizations of higher education in 2018. They use the indicators of the number of cooperation agreements and efficiency of cooperation – employment of graduates and the share of non-budget assets in revenues from the educational activities. These indicators are studied with the help of the method of regression analysis. The objects of the research are the flagship universities of the Central and the Southern Federal District of the Russian Federation.
Findings
Low efficiency of the educational cooperation of universities and companies of Industry 4.0 in modern Russia is observed. The authors show by the example of the flagship universities of the Central and Southern Federal Districts of the Russian Federation in 2018 that multiple agreements on their cooperation with the companies of regions in which they are located do not ensure high values of the indicators of employment of their graduates and the share of non-budget assets in revenues from the educational activities.
Originality/value
An algorithm of developing the educational cooperation of universities and companies of Industry 4.0 and a model of educational cooperation of universities and companies of Industry 4.0 are offered. The authors’ recommendations specify the conceptual foundations of the educational cooperation of universities and companies of Industry 4.0, as they orient the participants of this cooperation at achievement of specific formalized results and show the mechanism of achieving them.
PurposeThe purpose of the work consists in studying social integration as a factor of economic growth. The authors focus on experience and perspectives of developing countries, as they show the ...highest rate of economic growth and have high potential of its acceleration.Design/methodology/approachThe authors determine the interconnection between the processes of social integration in the four distinguished manifestations with the help of regression analysis and determine the level of homogeneity of data selections for each studied indicator with the help of variation analysis. Scenario analysis of future perspectives of the change of economic growth depending on the influence of the factor of social integration in the unity of its distinguished types is performed. Monte Carlo method is used for forecasting of change of the values of indicators of social integration.FindingsIt is substantiated that social integration is an important factor of economic growth. At the same time, the influence of this factor on economic growth of developing countries is ambiguous. Due to the offered proprietary classification of social integration according to the criterion of involved subjects, it is possible to establish that such types of social integration as integration of social groups, integration of business and society and integration of state and society have a positive influence. However, individual's integration into society has a negative influence.Originality/valueThe research contributes to development of economics by substantiating the significance of the social integration factor for economic growth and specifies the logic of management of this factor, which should be flexible. The perspectives of developing countries in acceleration of the rate of economic growth based on managing the factor of social integration are rather wide and envisage the increase of society's inclusion and the level of consumer consciousness and more active involvement of population into state management in the digital economy.
More complex activities, financial reporting, and risk aggregation of banking groups increase the
relevance
of research on their financial stability.
The purpose
of our study is to analyze the ...effectiveness of banking groups’ regulation in the Russian Federation and to develop proposals for its optimization.
The scientific novelty
includes the identification and proof of the hypothesis of the dependence of the banking groups’ financial stability on the level of the group control, as well as measures to improve the regulation of activities and financial stability of banking groups in Russia.
The research methodology
is based on a linear model on panel data (fixed effects models, random effects models, and pool models). The empirical base of the study includes data on the 26 largest Russian banking groups and parent credit institutions of banking groups from 2010 to 2020. A hypothesis was put forward that the financial stability of the banking group depends on the effectiveness of the regulatory control within the group. To confirm the hypothesis, the authors assessed the financial stability of banking groups using the Z
score
, while the banking groups were divided into two pools depending on the level of regulatory control. As a result, this hypothesis was confirmed. For banking groups with a high level of regulatory control, a model of financial stability and the factors that have the greatest impact on it were identified. The authors suggested the following measures to improve the regulation and financial reporting of the banking groups: 1) to expand the regulatory consolidation of the reporting of banking groups to the level of accounting, which will create the basis for a complete risk assessment; 2) to clearly define approaches to formalizing the assessment and management of the forced financial support risks for the group companies; 3) to unify the disclosure by banking groups of information about risks, methods for their assessment and management, including the relationship with the business model of activity. These measures are aimed at improving the risk management of credit institutions.
In the article it is studied the influence of higher education on the development of regional socio-economic systems. Economic and statistical analysis revealed the impact of measures of higher ...education development on the GRP of the region. Highly significant factors were: salaries of faculty staff of the universities and internal research and development costs. These indicators indirectly reflect the degree of intellectual development in the region and show the impact of intellectual capital development on socio-economic development. University professors develop students' knowledge, which allows them to institutionalize higher education and spread it in the region. The quality of a university professor’s intelligence directly affects the formation of intellectual capital in the region. In addition, it was significant the number of students studied in bachelor's, specialty, and master's programs. Moreover, the higher the number of students per capita, the lower the GRP per capita, which is explained by their low incomes. In the article it was considered the differentiation of Federal districts and regions of the Russian Federation in terms of the development of the higher education system. Methods of dividing indicators and grouping were applied, which made it possible to make cartograms and visualize the differentiation of regions by the number of higher education institutions and by the number of graduates.
It is indicated that domestic economy is experiencing a shortage of investment.The acceleration of the processes of import substitution is one of the most important challenges facing the domestic ...economy at present.Investments, especially capital investments and related investment relations constitute the basis for the development of the national economy and improving the efficiency of social production as a whole. A problem of formation of the amortization fundremains actual at the moment. In the modern scientific and educational literature amortization fund means the fund, including the use of funds to complete the restoration and repair of the fixed assets. This paper makesthe analysis of the situation in the area of investment in the fixed capital, which has developed in Russia for the past severalyears. The aim of this paper is to study the investment climate in the country based on the analysis of investments in the fixed capital by the sources of financing and types of the economic activity. The work is based on dynamic and structural analysis of analytical and statistical information on the processes occurring in this field.As a result, it can be noted that in spite of a number of efforts being made, in general, there are low growth rates in industry, there is a deficit of investments in the fixed assets. Most of the investments in fixed assets are carried out at the expense of the organizations’ own funds. A significant number of economic entities do not have the means, necessary for the technological renewal. Unfortunately, the regulatory framework in the field of accounting for the fixed assets and accrual of depreciation does not imply the use of a special account for the accumulation, and, most importantly, for the purposeful control of the use of the depreciation fund.First of all, it is necessary for companies with state participation and monopoly organizations. The lack of control over the targeted use of the depreciation fund led to a deterioration in the dynamics of indexes, characterizing the state and movement of the fixed assets, as evidenced by data on relevant indexes. Accelerated depreciation, used in tax accounting, should be monitored. However, at present, this only leads to an increase in costs. The article proposes accounting entries for the formation of an amortization fund and information on its intended use. In IFRS standards, information on the amount of accrued depreciation on fixed assets is generated in the reporting, which should also be shown in the financial statements of domestic organizations (especially with the state participation). Ambiguity in the interpretation of legislative and regulatory acts in the field of accounting for the fixed assets, accrual of depreciation and the formation of an amortization fund does not contribute to improving the investment climate in the country and leads to significant wear and tear in virtually all sectors of the economy. The article concludes that there is a significant underinvestment of the domestic economy, especially for manufacturing organizations.

Background. Identification of the genetic prerequisites for development of spinal deformity.
Aim. The aim of the study was to assess the frequency of distribution of alleles and genotypes for ...polymorphisms -3731A/G (Cdx2) and +61968T/C (TaqI) of the VDR gene and -1997G/T and +1245G/T (Sp1) of the COL1A1 gene in children with scoliosis of various etiologies and in healthy children.
Materials and methods. Clinical genetic testing was performed in 154 children with congenital scoliosis, 145 children with idiopathic scoliosis, and 278 children without an orthopedic pathology. The molecular genetic testing was performed by PCR.
Results. Genotype tt/GG VDR gene incidence is twice as high in children with congenital scoliosis than in children who do not have scoliosis (11% and 5.2% of cases, respectively; χ² = 4.17; df = 1; p = 0.04).
Conclusion. We have found that children with the allele carriers t(C) and genotype tt(CC) in patients with congenital scoliosis were significantly more likely than children without scoliosis spinal deformity.
