In this context, much attention is paid to the formation of reflexive skills of future managers that contribute to understanding, awareness, analysis, and evaluation of large amount of information. The lack of universal understanding in Pedagogy of the features of the process of forming reflexive skills among future managers proves the relevance of this study. The purpose of the article is to identify the features of the process of formation of reflexive skills among future managers in the system of secondary vocational education and to analyze the results of experimental work on the implementation of the developed organizational and pedagogical conditions in the educational process. Review of the scientific literature on the problem. The analysis and synthesis of professional and educational standards, normative legal documents of secondary vocational education is carried out. The analysis of scientific works of philosophers who have studied human reflection and thinking is carried out. The works on psychology devoted to the problem of understanding the essence of the process of reflection and the formation of reflexive competence of the individual’s personality in modern society are considered. In the field of pedagogical science and practice, the analysis of scientific works devoted to the competence approach and the study of the essence of the process of forming reflexive skills is carried out. The elements of the methodology of pedagogy and the theory of pedagogical research are systematized, in particular, the concept of humanization of the educational process, the methodology of personality-oriented learning, the competence approach, the theory of reflexive activity, on the basis of which systematization of an educational process is carried out within the framework of modern tendencies and trends. Methodology (materials and methods). Based on the research of scientific works of Russian and foreign authors devoted to the development of pedagogical theory and practice in the field of vocational education and arrangement of an educational process in vocational education institutions. The analysis and synthesis of practical methods and techniques that contribute to systematization of the process of formation of reflexive skills among future managers in the Secondary Professional Education (SPE) system is carried out. The analysis of scientific literature, a survey among teachers and heads of institutions in the SPE system, allowed us to identify and justify the features of the formation of reflexive skills among future managers in the SPE system and to develop organizational conditions for the process of developing these skills. The article shows the content, features, and results of the implementation of these conditions. Research results. The article deals with current methods and techniques that provide effective professional training of management students in the system of secondary vocational education, who are able to detect and formulate professional tasks and find ways to solve them. On the basis of the philosophical understanding of reflection, the content of reflexive skills aimed at discovering meanings in their own activities and in the “teacher – student” interaction is determined. The conditions for the formation of reflexive skills in the pedagogical process are revealed: creation and implementation of the typology of reflexive tasks; creation of a dialogic context in educational activities based on construction of the process of solving educational tasks; ensuring personal acceptance of the subject of a reflexive task; filling an educational process with a reflexive component; creation and implementation of the mechanism for development of reflexive skills among future managers in the SPE system. The results of the formation of reflexive skills in the system of secondary vocational education are presented. Conclusion. As a result of the conducted research, the organizational and pedagogical conditions for the formation of reflexive skills among future managers in the SPE system were developed providing a qualitative increase in the level of formation of reflexive skills among students. Consequently, the reconstruction of the educational process in the SPE system, based on the implementation of the presented organizational and pedagogical conditions, significantly optimizes the process of forming the reflexive skills among future managers.

The social welfare of the community, as a reflection of the quality of life, is characterized by a dynamic and complex nature, and is now becoming an increasingly relevant and more debatable topic in the scientific community. An integrated assessment of social welfare becomes the most important prerequisite for increasing the quality of life. The theoretical studies of social welfare assessment have shown that in order to assess it, a systematic approach is needed that distinguishes living quality factors and their groups and identifies the relationships between them. It is obvious that only the assessment of the existing social welfare situation can form the direction of improving the quality of life. In this article the authors, analyzing the issue of social welfare management as one of the most painful problems of the community today, define the concept of quality of life and social welfare, identify factors of social welfare quality and their assessment indicators, reveal the peculiarities of community-oriented activities. Based on the analysis of scientific literature, the authors of the article present a conceptual model illustrating community social welfare management and improving the quality of social life by responding to the needs of the community. The model consists of 5 main stages, each stage solving individual tasks. In the initial stages, an analysis of the current situation is carried out in the aspect of determinants of social welfare, the existing level is determined and comparison with the previous periods is performed. In the next stages a social welfare development plan is being prepared and implemented. According to the authors, applying the proposed model of social welfare management in the community, it is possible to ensure a higher level of social quality of life.

Abstract Small firms contribute to the economy by creating new vacancies and are the most common business form in the EU. However, small firms are not tended to expand internationally and only a limited number of small firms export to the countries outside the EU. The study aims to investigate inter-personal and inter-organizational networks in the international expansion of small firms. The investigation is grounded in analysis and synthesis of scientific literature. In addition, the bibliometric analysis was integrated into the scientific research. Bibliometric analysis of the papers published in 2000-2017 and obtained from Clari-vate Analytics database revealed that the significance of networking in international activities of small firms are not explored sufficiently while networking and internationalization of SMEs separately are a much more popular topic among researchers. The research results let us present insights for future investigations and implications for managers and policymakers.

SummaryThis article presents the results of studying the issue of the historical process of development the theory of mass physical culture in Ukraine.Based on the results of the analysis and synthesis of information obtained from domestic and foreign sources of scientific literature, we came to the conclusion that the process of historical development of the theory of mass physical culture in different regions of Ukraine took place with varying degrees of intensity.The analysis of statistical data for many years in different parts of Ukraine indicates that the origin and development of the theory of mass physical culture took place at different times.Historically, the need for such a theory has matured depending on the level of economic development of the region. So, for example, this process proceeded more intensively in those regions of Ukraine where industry and agriculture were more developed.In view of the fact that in these regions there was a high demand for labor, the question arose about maintaining the health of large masses of the population by means of physical culture.Therefore, in the Kharkov, Kiev, Dnieper, Zaporozhe and Lvov regions, wide networks of sports institutions began to develop, and the promotion of mass physical culture events was carried out at a higher level.Scientists have stepped up their activities, developing programs of mass physical education, adapted to the potential capabilities of the inhabitants of these regions and contributing to the strengthening of the health of the population, as well as the development of physical qualities necessary for effective work at enterprises and fields of the country.The most intensive process of involving the broad masses of the population in the movement of mass physical culture took place during the years of intensive construction of industrial facilities and the development of virgin lands.
