The lack of sufficiently developed methodological basis before graduation adversely affects the mathematical competency of future experts that are required by the modern economy. The study aims to investigate the features of the development of a personalized model of teaching mathematics by means of interactive novels to improve the quality of educational results. The main methods of research were the generalization of pedagogical experience and science literature, modelling, observation, analysis of results in AXMA Story Research methods. The chosen methods made it possible to justify the necessity of using interactive novels to personalize teaching mathematics and to confirm the qualitative improvements in the pedagogical system. Fisher's criterion was used to evaluate the results. 121 schoolchildren from Russian and Uzbek schools participated in the experiment. Individual educational routes supporting the studying of mathematical theory, problem solving in the interactive space AXMA Story Maker were developed. The peculiarities to be considered when designing a personalized model of mathematics learning by means of interactive novelties were formulated. These are the correlation between the didactic goal and the result of educational and research work in a nonlinear environment, the selection of the plot for a visual novel, the elaboration of the text component and the personalized learning track, etc. According to ANCOVA test results, the post-score of the experimental group is statistically higher than the control group. The results of the article can be used to develop ideas for personalising of learning in the digital school, as well as justification for the need for inclusion of digital interactive tools in mathematics education at all levels of education and training.

The purpose of this article was to identify the mechanism of bilateral feedback on Mathematics homework and to determine its impact on the success of schoolchildren learning. The following were used as the main research methods: the study and generalization of pedagogical experience which helped to consider possible ways of providing feedback on homework in Mathematics; the analysis of student artefacts with subsequent statistical processing. The latter made it possible to study the dynamics of students' knowledge of Mathematics and to judge the effectiveness of feedback on homework. The article reveals possible ways to provide feedback on homework in Mathematics deploying digital technologies; a scheme for meaningful feedback and ensuring its bilateral nature has been developed; the influence of the feedback in question on learning success was calculated. The implications of the study involve the fact that the developed didactic conditions ensure a bilateral nature of feedback during self-directed learning of Mathematics using digital technologies. This, in turn, contributes to the efficiency of the educational process and the provision of visible learning.

There is scarce evidence of a relationship between positive and psychosomatic characteristics. This study aimed to examine the associations of somatic burden with psychological resources such as optimism, resilience, and general self-efficacy. Russian participants (n = 1020) completed measures of psychological resources at Time 1 and somatic symptoms at Time 2. The results showed that somatic burden decreased with greater levels of optimism, resilience, and general self-efficacy. Regarding health and sociodemographic characteristics, female sex increased somatic burden in the model with optimism scores, university education decreased somatic burden in the model with resilience scores, and history of COVID-19 disease increased somatic burden in the models with optimism, resilience, and general self-efficacy scores. This study has theoretical and practical contributions. It combines positive psychology and psychosomatic medicine and highlights the value of psychological resource interventions in the treatment and prevention of somatic burden. These findings may be useful for scientists, clinicians, and practitioners. [ABSTRACT FROM AUTHOR]

Somatic burden has become one of the most common psychological reactions to the COVID-19 pandemic worldwide. This study examined the prevalence of somatic burden, latent profiles, and associated factors of somatic symptoms during the pandemic in a large sample of Russians. We used cross-sectional data from 10,205 Russians collected during October-December, 2021. Prevalence of somatic burden was assessed with the Somatic Symptom Scale-8. Latent profiles of somatic burden were identified using latent profile analysis. Multinomial logistic regression was used to examine demographic, socioeconomic, and psychological associated factors of somatic burden. Over one-third (37%) of the Russians reported being somatised. We selected the three-latent profile solution with high somatic burden profile (16%), medium somatic burden profile (37%), and low somatic burden profile (47%). The associated factors of greater somatic burden were female gender, lower education, history of COVID-19 disease, refusing vaccination against SARS-CoV-2 infection, poorer self-rated health, greater fear of COVID-19 pandemic, and living in regions with higher excess mortality. Overall, this study contributes to knowledge about the prevalence, latent profiles, and associated factors of somatic burden during the COVID-19 pandemic. It can be useful to researchers in psychosomatic medicine and practitioners in the health care system. [ABSTRACT FROM AUTHOR]

Objective: Previous studies highlighted a high prevalence of mental health issues among students during the COVID-19 pandemic, but there is no evidence from Russia. This study was aimed to examine the prevalence of somatic and psychological distress among Russian university students. Method: The cross-sectional study was conducted in March-April 2021. The participants were university students from several regions of Russia (N = 1236). The Patient Health Questionnaire-15 and Depression, Anxiety, and Stress Scales-21 were used to measure the somatic and psychological distress. Results: The prevalence of somatic burden, depression, anxiety, and stress was 72.2%, 54.7%, 63.4%, and 55.4%, respectively. Somatic burden, anxiety, and stress were more frequently observed in females and students with experience of COVID-19 disease compared to males and students without experience of COVID-19 disease. Conclusions: These data illuminate the high prevalence and potential risk factors for somatic and psychological distress among Russian university students and determine the importance of psychoeducation and preventive measures in the Russian university environment.

At the end of the twentieth century, the mission of the discursive practice of popular science magazines was to draw public attention to environmental issues. The peak of interest in ecology fell on this period: environmental problems in Russia occupied the front pages of newspapers and magazines and featured widely on radio and television. By the mid-2000s, the level of interest in environmental issues had decreased markedly. Environmental issues in popular science magazines gave way to entertainment. Today, many environmental magazines provide tourist information in the format of creolized texts about holiday destinations, a healthy lifestyle, or the life of celebrities. Arguments calling for the preservation of the environment and sustainable lifestyles have been replaced by arguments calling for a life of enjoyment. This paper discusses the concept of a master degree course in argumentation in journalism as illustrated by the evolution of environmental argumentation in the popular science magazine, Vokrug Sveta.

After the assassination of Sheikh Said-Efendi of Chirkei in 2012, Russia's security and law enforcement organs returned to the coercive method of anti-terror war and began to repress the moderate (non-violent) Salafis in Dagestan. This change coincided with the governorship of Ramazan Abdulatipov, who intervened intensively in local politics. The Dagestan Muftiate, guided by the ethnic Avars and Shaikh Said-Efendi's disciples, exploited this situation to expand their influence to South Dagestan. Based on county-level fieldwork, we identified three patterns of interaction of secular and religious actors in South Dagestan: the strongholds of the local Sufi order guided by Sheikh Sirazhudin and Isamudin, which survived Abdulatipov's governorship; the equidistant local religious regimes, which Abdulatipov overturned on the pretext of their tolerance towards moderate Salafism; and (in Derbent County) a three-way battle between Sirazhudin-Isamudin's order, the Dagestan Muftiate, and the moderate Salafis in which the first continues to dominate.

The paper presents the robust estimates of tail indices for financial returns and returns asymmetry in the Russian stock market. We also investigate the relation between individual characteristics of companies and the degree of heavy-tailedness and asymmetry of returns. According to our estimates, the degree of heavy-tailedness is strongly related to the liquidity of stocks and the company size. At the same time, no significant effects on estimates of the tail indices of sectoral affiliation, cross-listing, adding into quotation lists, state ownership are revealed. As for the influence of the above-mentioned factors on the asymmetry of returns, the statistical reliability of relevant models is rather low. However, certain indicators of the asymmetry are observed for medium-sized regional companies, the majority showing a heavier right tail compared to the left tail. We also discuss the implications of our findings for managerial decisions and economic modeling. Our results may be useful for risk-managers, financial regulators, investors and policy-makers.

Despite the escalating terrorist actions, there is no polarized constellation in the Islamic politics of Dagestan. Russia's Federal Security Service (FSB) officers regard the corrupt Dagestan authorities to be significantly responsible for the massive conversion of youths to terrorism, and began to contact with moderate Salafis to isolate the “forest brothers” (armed Salafis) in 2010. Exploiting the FSB's soft strategy, secular intellectuals requested to reform the Muslim Spiritual Board of Dagestan by electing a legitimate mufti. Having seen the incompetence of intra-Sufi opposition (non-Avar sheikhs) in the War on Terror, the Spiritual Board jumped on the bandwagon of dialog strategy in 2012. The secular authorities of Dagestan, indifferent to intra-Muslim politics, limit their activities to the call for dialog between the secular authorities and the forest brothers. In this way, political actors hijack the master narrative of the “War on Terror” and these narratives are imported to local politics. [ABSTRACT FROM PUBLISHER]

Abstract: Picroilmenite samples from five kimberlite pipes of the Yakutian kimberlite province have been studied. Point microprobe analyses of two mutually perpendicular profiles of each sample were carried out to study the compositional inhomogeneity of picroilmenite. Thermomagnetic curves were also recorded for each sample. A model for the processing of thermomagnetic curves is proposed on the basis of the relationship between the Curie point of picroilmenite and the content of the hematite end-member. The compositions determined by the thermomagnetic curves and microprobe analysis are rather similar. The conclusion has been drawn that thermomagnetic analysis can be used for the rapid determination of the picroilmenite composition. The possibilities and restrictions of this method are shown.
