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.

The article is devoted to the study of the problem of virtual modeling of historical events and processes. It is noted that the modeling of social and historical processes began to be developed as a method for studying society only from the 70s-80s of the XX century. At the turn of the XX - XXI century, such an interdisciplinary direction as cliodynamics, devoted to the modeling of historical processes based on mathematical methods, appeared. The emergence of this scientific direction shows that the topic of modeling historical processes is based on the methodology of mathematical modeling. The article draws special attention to the virtualization of modern society as a factor in improving the modeling method. Computer technologies are becoming the main means, which greatly simplifies the modeling technology. Problems in creating a model of historical processes are noted, which is associated with a source study basis, the use of additional technologies, and it is also necessary to take into account the complexity, irreversibility, nonlinearity of the historical process itself. Also, as an example, ABM (agent-based models) are given, as an example of imitation and visualization of objects, phenomena. Among the individual characteristics of virtual modeling, the author identifies the ability to create a plausible imitation of an event, interactivity, information content, the ability to change / correct the intended nature of the process or the result of an event, unlimited time and space. This is the advantage of virtual modeling as a method of modern reconstruction of historical events, especially those that do not have accurate data, are debatable. Moreover, the article points out that this type of modeling has already embraced even those historical sciences that were more problematic in this regard (archeology, paleontology).

The objective assessment of the state and development of socio-economic phenomena and the processes can only be ensured by the use of properly selected statistical and mathematical methods. These methods cease to be a matter of interest in practice when there is no certainty as to how much they can be applied to specific tasks. In the context of significant advances in technology for the collection and processing of statistics, the skilled use of statistical and mathematical methods is significantly hampered by a lack of knowledge of methods and their ability to evaluate information. The article highlights the criteria for choosing the best equation of dependencies as a means of statistical analysis of the influence of factors on the results of socio-economic development of the national economy as a whole, including individual types or forms of economic activity. It has been shown that the statistical dependency method can be used to solve the tasks set out in the article. The method of statistical dependence equations is a statistical method of analyzing the causal relationships of economic phenomena and processes. Unlike the mathematical method of correlation and regression analysis, which is based on linear algebra, the application of the method of statistical equations of dependencies is based on the calculation of the coefficients of comparison, which are determined by the ratio of the individual values of the eponymous sign to its minimum or maximum level. With increasing values of the sign, the coefficients of comparison are calculated from the minimum level, and at decrease — from the maximum. The comparison coefficients show the degree of change (increase or decrease) of the magnitude of the trait to the accepted comparison base. The parameter of the equation of dependence is calculated on the basis of the coefficients of comparison of the resultant and factor trait. Unlike the coefficients of elasticity known in statistics, the parameters of the equation of dependence, which are determined by the method of deviations, allow to take into account not only the influence on the effective attribute of one factor, but also the cumulative effect of many factors.

The research in question is based on the gender schema theory by Sandra Bem. The purpose of the research is to study male narrative features in the context of the norms of male socialization. The aim of the research under consideration is a comparative analysis of male and female autobiographies features, which are not confined to male and female speech characteristics and reflect revision of gender socialization norms by the subject. With the help of biographical interview method autobiographies of women aged 31 to 72 (N= 34) and men aged from 23 to 69 (N= 36) living in provincial Russian towns were transcribed and contrasted. The autobiographies underwent categorial analysis procedure conducted by experts; the obtained categorial matrices were processed with the use of mathematical methods of statistics. Considerable attention was given to men’s life stories during the process of analysis. Quantitative data analysis allowed to reconstruct the structure of men’s and women’s autobiographies, which reflected gender socialization norms. The obtained algorithm, being geared towards the search for gender markers in the autobiographies, identified gender-specific markers in men’s texts whereas the female ones were retrieved owing to non-specific categories. This allowed to conclude that the modern Russian male socialization practices are more traditional. According to the results of the research, the categorial structure of autobiographical texts in men and in women is similar in key events and specific to each gender group at the same time. As far as gender normativity is concerned, male stories are more frequent to contain the gender norms abidance markers. Female stories are more individualized and fall into different scenarios (gender-standardized and non-standard).

Scientometry methods meet the requirements of digitalization and e-management of the science, development due to the widespread use of mathematical methods of information processing. To assess the scientific productivity of scientists and specialists in scientometrics, various indicators are used, the most common of which is the Hirsch index or h-index. The Hirsch index is calculated from the number of citations of the researcher’s works included in a certain database.For CIS countries, an important database of scientific and educational publications is the database of the Russian Scientific Citation Index (RSCI). One of the problems with using the Hirsch index is the compliance of assessments with copyright rules. The Hirsch index shows the comparative effectiveness of the work of a scientist or team of scientists. But as it is not difficult to see, according to the Hirsch index counting indicators for the RSCI databases, for individual scientists their contribution and participation in collective publications and their citations are not taken into account. It is proposed to introduce a modified Hirsch index, called the Hirsch index “plus” or h +, which is calculated on the basis of dividing the usual number of citations of a particular publication by the number of co-authors of the cited publication, which will not cause difficulties in calculating h + indices, using the algorithm for determining the Hirsch index itself. Such an indicator corresponds to copyright rules, takes into account the interests of co-authors from the point of view of copyright and more accurately assesses the effectiveness of the work of a particular author when comparing the work of scientists.Modern scientometrics is a necessary tool for research on the development of science, forecasting and managing its development, some of the indicators of which are citation indices, in particular, the most common in practice is the Hirsch index, and the Hirsch “Plus” index and other modifications to take into account the individual contributions of scientists and specialists. Each of the existing modifications of scientometric indices can be used to investigate the publication activity of scientists and specialists depending on the specifics of the tasks set, taking into account the complexity and convenience of calculating specific indexes.

The paper discusses the problem of determining the most influential people on social media while taking into consideration the possibilities of forming coalitions with their sets. The authors analyze social media networks created by criminal elements. Modern Russia has a practice of criminal and administrative prosecution of social media users who post information that violates Russian legislation. Today, there is an opportunity to study various aspects of society and obtain new research results using social media, which often play a key role. The authors suggest that the methodology of identifying social media users who are sources of extremist information should be examined and streamlined with the goal of improving the law enforcement practice of counteracting the spread of socially dangerous information on the Internet. They use mathematical methods to show that the problem of finding the maximally influential group consisting of k number of participants cannot have an optimal solution if this group includes k most influential participants individually. To solve this problem, the authors suggest using the game theory concept of Shapley vector, which makes it possible to evaluate the individual contribution of each participant into the formed group, i.e., to find out to what degree each of them could be useful as a team player. Law enforcement bodies already have certain experience of using software to upload data and analyze social networking sites. The presented method of calculating the significance of network users gives an opportunity to widen and improve this experience and to move from the ad hoc selective prosecution of separate users to the methodical work of suppressing and preventing crimes connected with the dissemination of information that constitutes an offence. The research area selected by the authors will, in its turn, contribute to improving the effectiveness of suppressing and preventing crimes connected with spreading information that contains constituting elements of different offences.

The development of adequate measures to combat the spread of socially significant diseases requires the use of modern tools available to demographers and epidemiologists for entering, analyzing and visualizing data on the spread of population movement processes in space. A medical and demographic geoinformation system has been created to study the dynamics of suicidal behavior in the Amur region of the Russian Far East. The main factors involved in the psychopathogenesis of suicidal behavior are considered. The research was conducted using various ecological and mathematical methods to assess the quality of life of the human population in extreme the conditions of the Far Amur region of the East of Russia, taking into account various factors of interaction between the individual, society and the environment. The features of the spread of suicidal attempts in the Amur region are revealed. The set of the main causes and factors of low intensity characterizing the current suicidal situation in the Amur region of the Russian Far East is studied on the example of the Khabarovsk city. The medical-demographic and socio-psychological problems of suicidal behavior caused by depressive disorders are analyzed from the standpoint of the geoinformation modeling method. Original methodological approaches to the use of information models for medical-demographic and socio-economic studies of depressive spectrum disorders and the prevention of adolescents suicidal behavior are proposed.

Introduction. The concept of sustainable development defines the socio-ecological direction as the leading one in the system of interaction between society and nature, which emphasizes the importance of continuous socio-ecological education of the individual. Continuous socio-ecological education in the interests of sustainable development provides not only the solution of socio-ecological problems, the co-evolution of society and nature, but also the upbringing of an ecologically cultural and educated person, where the leading role is assigned to the teacher. Modern higher pedagogical education is a mechanism for the development of the socio-ecological education of a future teacher, which determines the readiness of the last to implement continuous socio-ecological education of students. Materials and methods. The experimental study involved 285 students enrolled in the educational program "Pedagogical education". The study was based on the Tobolsk D.I. Mendeleev Pedagogical Institute (branch of Tyumen State University), BI HE KhMAO-Ugra "Surgut State Pedagogical University". The study was based on theoretical, empirical, survey-diagnostic and mathematical methods (Fisher φ-criterion). Research results. A theoretical systematic analysis of the literature made it possible to reveal the content of the concepts of “socio-ecological education for sustainable development”, “socio-ecological education of a teacher”, to develop and present the structure and process of development of socio-ecological education of a teacher, which fills and enriches the theory of pedagogical science with new knowledge. The statistical analysis of the results obtained showed the reliability of differences in the level of development of the socio-ecological education of the future teacher in motivational-value (φemp = 5.78; p≤0.01), cognitive (φemp = 6.80; p≤0.01), activity (φemp = 4.89; p≤0.01) and reflexive-regulatory components (φemp = 7.28; p≤0.01), which indicates the positive dynamics of the level of development of socio-ecological education of the future teacher. Conclusions. The conducted experimental work showed the effectiveness of the implemented organizational and pedagogical conditions in the process of professional training of a future teacher for continuous socio-ecological education in the interests of sustainable development of society and the positive dynamics of the development of socio-ecological education of a future teacher, the reliability of which was statistically confirmed using the Fisher t-criterion.
