Stationary configurations of two extreme black holes obtainable from the Kinnersley-Chitre solution

Stationary axisymmetric systems of two extreme Kerr sources separated by a massless strut, which arise as subfamilies of the well-known Kinnersley-Chitre solution, are studied. We present explicit analytical formulas for the individual masses and angular momenta of the constituents and establish the range of the parameters for which such systems can be regarded as describing black holes. The mass-angular momentum relations and the interaction force in the black-hole configurations are also analyzed. Furthermore, we construct a charging generalization of the Kinnersley-Chitre metric and, as applications of the general formulas obtained, discuss two special cases describing a pair of identical co- and counterrotating extreme Kerr-Newman black holes kept apart by a conical singularity. From our analysis it follows in particular that the equality $m^2-a^2-e^2=0$ relating the mass, angular momentum per unit mass and electric charge of a single Kerr-Newman extreme black hole is no longer verified by the analogous extreme black-hole constituents in binary configurations.Comment: final version revised according to referee's suggestion

Semantic context of professional identity crisis experience by teachers

The topicality of the problem under research is predetermined by the need of psychology and pedagogy for the study of the phenomenology of professional identity crisis, the process of its experience by school teachers as well as for the development of the system of psychological and pedagogical support of teachers' professional development in the situation of permanent changes in the education system. The objective of the study is to reveal the content of the professional identity crisis, to describe its main features and analyze the semantic context of its experience by teachers. The principal methods of study of this problem are the phenomenological method, tests to identify the semantic context of the process of the professional identity crisis experience by teachers. The results of the study broaden the understanding of the phenomenon of professional identity crisis and its experience, the content of professional crisis and the phenomenology of professional development of teachers. The materials of the article may be useful for psychologists when designing programs of psychological support of teachers´ professional development. © 2017, Slovenska Vzdelavacia Obstaravacia.

Specifics of defense and coping behavior among teachers experiencing a professional identity crisis

The issues addressed in the article are of particular relevance due to the necessity to provide research background for creating the system of psychological and pedagogical support for the professional development of teachers in the conditions of permanent changes in the system of education. The aim of the article is to describe specific interrelations between the reflection and the parameters of the teacher's axiological sphere (in particular, life-purpose orientations). The following research methods were used: theoretical analysis of psycholog-ical and educational literature, phenomenological method, questionnaires, and methods of mathematical and statistical data processing (descriptive statistics, comparative analysis (the Mann-Whitney U test). The results of the theoretical and empirical research provide ade-quate grounds for the conclusion that there is a definite interrelation between the parameters of reflection and the parameters of life-purpose orientations. It is proved that in the conditions of a professional identity crisis the teachers experience a significant reduction in the levels of life-purpose orientations, which in turn leads to intensification of reflection processes. At the same time, the obtained results suggest that the teachers can successfully overcome their professional crisis in case of formation of the cognitive component of the biographical reflection, aimed at the analysis of actions and means of understanding and organizing their life events. Implications of the research results. The research results expand our understanding of the essence and emotional experience of the professional identity crisis. They can be used in the designing the process of psychological support for the activities and professional development of teachers. © 2018 Authors

Foundation of psychological support in the emotional experience of professional identity crisis by teachers

The background of the researched problem is determined by the psychological and pedagogical science’s and practice’s need to supplement the ideas about teachers’ professional development and about the course of their getting through the emotional experience due to difficulties of this process; as a result, it is necessary to study psychological foundations of building of psychological support programs in the process of school teachers’ getting through a professional crisis under conditions of permanent changes in the educational system. The main approach to studying this problem is the interview and phenomenological method that allows to identify and justify psychological basis of building of teacher support programs. The theoretical analysis allows to identify the nature of the support process, its goals and objectives, and to justify the methodological basis of the support program realization. The empiric results demonstrated that the process of teachers getting through the professional identity crisis goes hand in hand with the value-semantic transformation of a person and with “launching” of reflexive processes which, in turn, justifies resorting to them as to the psychological basis of building of teacher support programs. The research results expand the understanding of the nature of professional identity crisis phenomenon, the process of coming through it and supplement the data of the basis of building of teacher support programs. © 2018 by the authors

Inequality degree within the country in the context of realising the Sustainable Development Goals

The article assesses the inequality degree within Russia in the context of realising the Sustainable Development Goals. The review of foreign and domestic scholarly writings, focusing on current issues of implementation and achievement of the Sustainable Development Goals, is presented. The authors reviewed the indicators development degree of sustainable development in Russia as of December 2021. It is determined that Goal 3 “Ensure healthy lifestyles and promote well-being for all at all ages” is the most fully disclosed. Based on the National Indicators of Goals 3, an original system of statistical indicators for assessing inequality between regions has been compiled and substantiated. According to the indicators presented in the above-mentioned system, the clustering procedure of the Russian regions was carried out, and the assessment and interpretation of the selected clusters were given. The content distribution into typological groups was practically not influenced by territorial affiliation. A significant role was played by direct indicators, included in the indicator system, and indirect factors, affecting both the development of the region and the socio-economic well-being of the inhabitants of these regions. The authors believe that there remains relevant to study the transformations that the two divergent flows will take place in the coming years: 1) existing national projects and state programmes to solve the tasks and achieve the planned values formulated in the National Set of Sustainable Development Goals Indicators in the part of Goal 3; 2) the current epidemiological situation, which in the period 2020–2021 has already made tangible changes in the size and composition of the population
