The textbook extensively covers the most pressing issues of antimonopoly and tariff regulation. The basics of antimonopoly and tariff regulation are outlined, the main activities of the Federal Antimonopoly Service as a state regulator, its functions, powers and responsibilities in the implementation of state antimonopoly control and tariff policy, as well as issues of sectoral tariff regulation and control over economic concentration are considered. Separate chapters are devoted to: types of unfair advertising and measures of responsibility for its placement; control of procurement activities. Various approaches to assessing the prospects for the development of corporations in a competitive environment are presented, for example, PPP, which, on the one hand, acts as a development tool, and on the other — as an object of antimonopoly regulation. The essence of the antimonopoly compliance method, which is used to prevent regulatory risks, is disclosed. Meets the requirements of the federal state educational standards of higher education of the latest generation. For students studying in the areas of training "Management" and "Jurisprudence" (bachelor's and master's levels), studying issues of competition, antimonopoly control and tariff policy from the point of view of management in these areas.

Certain features of socioeconomic models can be distinctly determined in different countries and regions. However, such models are quite flexible under external and internal influences. Their changes can be observed under the impact of unpredictable factors, the COVID-19 pandemic being one. The aim of the work is to identify differences in the structure of socioeconomic models under the influence of the pandemic. The object of the study is the socioeconomic models of various states. The subject of the study is the transformation of socioeconomic models at different stages of the pandemic. Research methods include analysis of statistical data, correlation and comparative analysis, and graphical methods of presenting results. A comparison of data from the most well-known socioeconomic models was carried out for the first time. It is determined that the countries of the Chinese model adopted restrictive measures of high Stringency Index. The countries of the Japanese model used unique crowd management methods, and the countries of the Scandinavian, German and Anglo-Saxon models resorted to unprecedented monetary injections into the social and economic spheres. It was revealed that quarantine measures eventually cost countries less than monetary injections. It was shown that a decrease in the Pandemic Uncertainty Index stabilized the economic behavior of the population and businesses and increased the volume of export-import operations. It was found that the pandemic affected the economy indirectly through the level of uncertainty and rigidity of preventive measures. It is assumed that the intensity and severity of measures could be influenced by global trends leading to certain types of preventive measures rather than by the COVID-19 statistics of a particular country.

Sectoral structures are one of the critical and dynamic components of any social system subjected to either external or internal factors. The purpose of the paper is to reveal and validate characteristic features of transformation regarding economic sectoral structures during the crisis of the socio-economic system and the period of its coordinated development in order to determine the most stable industry sectors. This paper reveals the specificity of sectoral transformations in European countries during the crisis of 2008–2009 and the stable growth of 2010–2019. The analysis is premised on Robert B. Reich’s sectoral structure, comprising production, in-person, intellectual, and communication services sectors. To conduct the research, statistical data analysis using the Gatev coefficient, and correlation and comparative analysis are applied. It is concluded that the mutable nature of sectoral dynamics depends on the planned changes resulting either from business expectations and interests, or state intervention. Yet, transformation is likely due to external and internal shocks (economic upheavals and wars), and unexpected events (natural disasters, epidemics, and pandemics). Over the last 15 years, the sectoral structure has been subjected to most of the above collisions. In-person, intellectual, and communication services sectors are least affected during the economic crisis. In the European countries, the period of economic growth is characterized by the growing dominance of intellectual and communication services sectors. There is a trend of decreasing the share of mining and quarrying in the sectoral production structure in favor of manufacturing industries and services.

The object of the research is represented by foreign employees working in the Russian Federation as part of the multinational personnel of the organization. The aim of the work is to develop theoretical provisions and practical recommendations to increase the level of sustainability of multinational organization development on the basis of effective management of international staff loyalty and its optimal use. The work used complementary methods of questioning and expert survey, based on the assessment - Likert scale with subsequent comparison of the actual state of management processes with expert assessments, determining the sustainability of organizational development. The system of factors influencing the formation of multinational personnel loyalty in the organization was formed, focusing on the importance of mechanisms of adaptation and motivation of foreign workers. The method of predicting the performance of enterprises on the basis of calculation of the recommended level of use of adaptation and motivation processes which form the loyalty of multinational personnel in organizations is proposed. The method is based on the expression of traditionally qualitative indicators of human resource management in quantitative formats in order to determine the regression dependences of the sustainability of organizations’ performance on the initial processes of personnel management. The scientific novelty of the research results consists in substantiating the specifics of forming the loyalty of multinational personnel and developing practical recommendations aimed at enhancing the sustainable development of multinational organizations, taking into account the cross-cultural characteristics of human resources. The application of the author's methodology and algorithm in the practice of organizations with multinational staff allows to estimate the level of actual use of factors influencing the formation of multinational staff loyalty and their significance, as well as to develop a set of measures aimed at increasing the sustainability of organization development.

Impella® pumps are increasingly utilized in patients in cardiogenic shock. We report on a case series where Impella support was insufficient, and a switch to venoarterial extracorporeal membrane oxygenation (VA ECMO) became necessary. ECMO patients with previous Impella devices were identified utilizing our institutional ECMO database. Since 2014, 10 patients with a mean age of 62 ± 3 years were identified. Despite correct placement of all Impella pumps, cardiogenic shock persisted with progressive multi-organ failure (Impella type 2.5/CP n = 6/4 patients). Femoro-femoral VA ECMO was implanted percutaneously on the contralateral side with the Impella initially left on standby but retracted into the descending aorta for transport reasons after a mean support time of 20 ± 8 h. All patients were able to unload their heart by left ventricular ejection with a blood pressure amplitude of 15 ± 3 mmHg on VA ECMO support. After VA ECMO implantation haemodynamic parameters improved significantly within 24 h of support (mean serum lactate levels decreased from 92 ± 17 to 44 ± 10 mg/dl, P = 0.031). Survival to hospital discharge was 70%. These data indicate that the Impella 2.5® and CP® might not be sufficient in profound cardiogenic shock. Comparative studies are necessary to specify which patient population benefits from which type of circulatory support.

The regional tourism industry along with its various components and stakeholders involved in the development of regional tourism products (TP) and the value chain can be interpreted as ecosystems. A concept of creating a regional cross-sectoral ecosystem is presented and described. It brings together all interested parties (actors), including government authorities and various business representatives. The approaches to determining the level of attractiveness of a region for the formation of a tourism ecosystem based on the assessment of its tourism potential (TP) are the research subject. The research methodology presents an algorithm for assessing the tourism ecosystem formation attractiveness through assessment of key performance indicators assessing territorial TP. The purpose of the study is to develop strategic guidelines for increasing the efficiency of using tourism potential to form a regional ecosystem (a case study of the Penza Region). The conducted analysis has highlighted strategies (institutional; business image; cultural and educational; innovation and technology) that determine the key vectors for the development of tourism potential of the Penza Region.

The article provides methods for assessing the compatibility of elements in the design of complex technical systems. The compatibility of the elements is considered as the main indicator that determines the quality of systems including heterogeneous elements. The presented methods make it possible at the design stage to choose a technical solution that is most suitable for the project objectives, taking into account the operating conditions of the system. The methods make it possible to evaluate compatibility by a single and complex indicator. The choice of indicator depends on the purpose of the assessment. An example of methods implementation in the design of systems including an electric drive and pipeline shutoff valves is considered. It has been experimentally proved that in systems with low values ​​of the compatibility level, the actual power characteristics exceed the required values, which leads to additional voltages in the system elements and their breakdowns. The results of the assessment of typical systems allowed to identify the shortcomings of existing structures and propose alternative solutions to problems. The compatibility of elements within the framework of a technical system makes it possible to increase the functional efficiency of systems with minimum weight and size and power characteristics, to optimize the price-quality ratio, and to increase the competitiveness of the final product.

Over a thousand universities and their branches represent the Russian higher education system today.

Russian Abstract: (Исследование социального положения инвалидов в Российской Федерации с использованием разнообразных методов: от статистического анализа до социологических исследований с целью выявления наиболее адекватного инструментария для внесения предложений по включению в систему Национального мониторинга инвалидов в Российской Федерации, который должен осуществляться в свете Конвенции ООН о правах инвалидов.)English Abstract: The research on social status of the disabled people in the Russian Federation is made using a combination of different methodological approaches and covering all possible databases. We make a critical review of existing statistical and sociological tools of disabled people research, developed the most adequate methodology to study socio-economic status of disabled persons and their problems, and conducted a survey of this extremely vulnerable group of the population. The research is carried out with regard to the provisions of the UN Convention on the Rights of Persons with Disabilities. We conclude that approaches to disability in current Russian statistics do not correspond to the requirements of the Convention and this information gap could not be bridged by one survey. Therefore we transform the Rosstat set of indicators for disabled people to be consistent with the Convention, we develop and test the methodology for longitudinal surveys, and recommend the Ministry of Labour of Russian Federation to implement these new tools of disabled people research.
