Transformation of the system of bilingual education in the Republic of Tatarstan: Crossover ethnolinguistic controversies

© 2017, Association for Social Studies Educa. All rights reserved. The relevance of the problem range addressed in the study is conditioned by the system of education functioning under multiculturalism in modern polyethnic societies and their social stability much depending on the balanced use of languages of ethnoses that reside in the region as well as on the respectful attitude to their representatives in daily life. Thus, the system of education has to take into account the ethnic and religious, political, social and cultural requirements of the society offering high-quality education to the consumers according to their expectations. The objective of the paper consists in revealing the topical problems of regional educational reforms aimed at implementing the principle of bilingualism in polyethnic and polyreligious region of Russia – the Republic of Tatarstan. The representative mass survey of population of the Republic of Tatarstan and a series of in-depth narrative interviews with representatives of various generations of Tatarstan citizens as the main methods used in the research. Based on the sociological survey conducted within the research project “Dynamics of real and conventional generations in information polyethnic and polyreligious society (a case study of the Republic of Tatarstan)”, the following findings have been made. Scientific justification of the language policy being implemented in the republic and of the methodological support of bilingual educational programs are of poor level. A higher education system segregated according to the information carrier language prevails. There also remains a crossover controversy expressed in discontent in both Russian-speaking and to a significant extent Tatar-speaking urban population with the school educational policy of bilingualism. Results of the research cited in the paper can be used by the state authorities of the republic for elaborating the optimum bilingual language policy as well as in the practice of educational institutions implementing the bilingual education

Generational features of ethnic personal identification in a MultiEthnic society

© 2018 Transilvanian Association for the Literarure and Culture of Romanian People (ASTRA). All rights reserved. The paper deals with the thesis about the generational factor's influence on personal identification in conditions of a multi-ethnic society. Based on input received through the representative survey held in the multi-ethnic and multi-confessional region of Russia - the Republic of Tatarstan, the authors recorded the enhanced relevance of ethnic identification in elder and younger generations and the absence of the sharp ethnic bias as well as religious intolerance in all generations. The study identified the following categories of intergenerational relationships: optimists, pessimists and fatalists. The analysis revealed the higher level of ethnic identity among the Tatar population of the region as compared with the Russian one. It was justified that in order to preserve inter-ethnic tolerance in a multi-ethnic society it is necessary to ensure social and cultural continuity of generations by promoting optimal combination of macro- and micro-social identifications of both traditional established forms and modernist, especially postmodernist types

Russian education in the context of the third generation universities` discourse: Employers’ evaluation

© 2016 Maximova et al.Urgent problems of modernization of the Russian system of higher education in the context of the discourse of the third generation universities were revealed on the basis of the expert survey of employers (heads of personnel departments of large industrial enterprises of the city of Kazan and the Republic of Tatarstan) within research project “Strategy development of socio-economic development of the Republic of Tatarstan for the period till 2030”. These include: insufficient level of professional skills and competencies of graduates in recent decades; decrease in motivation of young specialists in employment and work in the industrial sector; formal activities aimed at enhancing interaction between universities and companies due to the lack of financial and material resources. To improve the quality of young specialists` training, experts offered recommendations such as improving the system of practical training of students, modernization of the educational process through the use of new educational technologies and active involvement of employers into the development of educational plans and programs, improvement of the quality of teaching university staff

Термоэлектрические явления и устройства в концепции Ландауэра–Датты–Лундстрома

С позиций концепции «снизу–вверх» транспортной модели Ландауэра–Датты–Лундстрома современной наноэлектроники рассматриваются термоэлектрические явления Зеебека и Пельтье и качественно обсуждаются закон Видемана–Франца, числа Лоренца и основные уравнения термоэлектричества с четырьмя транспортными коэффициентами (удельное сопротивление, коэффициенты Зеебека и Пельтье, электронная теплопроводность). С тех же позиций на примере 3D-резистора в диффузионном режиме анализируется работа термоэлектрических охладителя и генератора энергии с учётом лишь электронов, как реальных носителей тока, так и в рамках умозрительной, но удобной «дырочной» модели, вводятся и определяются понятия эффективности работы (КПД, фактора мощности и добротности) термоэлектрических устройств и рассматривается, каким образом транспортные коэффициенты зависят от свойств термиков.З позицій концепції «знизу–вгору» транспортної моделі Ландауера–Датти–Лундстрома сучасної наноелектроніки розглядаються термоелектричні явища Зеєбека і Пельтьє і якісно обговорюються закон Відеманна–Франца, Лоренцові числа й основні рівняння термоелектрики з чотирма транспортними коефіцієнтами (питомий опір, коефіцієнти Зеєбека і Пельтьє, електронна теплопровідність). З тих же позицій на прикладі 3D-резистора в дифузійному режимі аналізується робота термоелектричних охолоджувача і ґенератора енергії з урахуванням лише електронів, як реальних носіїв струму, так і в межах умоглядної, але зручної «діркової» моделі, вводяться і визначаються поняття ефективности роботи (ККД, фактора потужности і добротности) термоелектричних пристроїв і розглядається, яким чином транспортні коефіцієнти залежать від властивостей терміків.Based on the ‘bottom-to-top’ approach of the Landauer–Datta–Lundstrom transport model of state-of-the-art nanoelectronics, the thermoelectric Seebeck and Peltier phenomena are considered; the Wiedemann–Franz law and Lorenz numbers as well as the four transport coefficients (specific resistivity, Seebeck and Peltier coefficients, and electronic thermal conductivity) are qualitatively discussed. From the same positions for 3D-resistor within the diffusion regime, thermoelectric cooler and energy power generator are analysed with accounting only electrons as real current carriers as well as within the scope of the artificial but useful ‘hole’ model. Conceptions of operating performances (coefficient of efficiency, power factor, and figure of merit) for thermoelectric devices are introduced and defined, and dependences of transport coefficients on the properties of termics are discussed

Heterogeneity of population of microorganisms grown in presence of iron oxide maghemite nanoparticles

In this work γ-Fe2O3 MNPs were obtained by laser target evaporation and water based suspensions were prepared. Maximum permissive dose of iron in water (MPD) is 0.3 mg/L. It was found that 100 MPD dose of iron induces formation of non-typical colonies after 72 or 96 hours exposition: against a background of small black colonies large white colonies appeared due to a disruption in tyrosine synthesis. Multiple re-cloning of the white colonies grown with MNPs showed that they retained their properties both under standard conditions (temperature of 24 °C) and at the temperatures up to 37o C. E.nigrum grown with MNPs demonstrated very scant extension of small colonies at the cultivation temperature of 24o C, their growth was completely blocked at 37°C. Significant changes in the structure of the population were noted. First of all, large cells with pronounced aggregation were observed among the black colonies. These aggregates consisted of large cells connected to each other by matrix. In the white colonies the appearance of very long threadlike cells connecting different groups of the cells establishing an intercellular communication was evident. Fe2O3 MNPs induce an increase in the heterogeneity of the population, expressed as a change in morpho-physiological states. © 2018 The Authors, published by EDP Sciences.The work was supported by the Ministry of Education and Science of the Russian Federation (project No. 3.6121.210 )7 and R FFI №16-34-015 92 grant s. e tW hank R ndrA ade, Iu.

A structural equation model relating adiposity, psychosocial indicators of body image and depressive symptoms among adolescents. Int J Obes (Lond

Objective: Psychosocial factors, including pressure to be thin and body dissatisfaction, have been hypothesized to mediate the relationship between obesity and depression, especially during adolescence when vulnerability to social pressures around body shape and image is heightened. The objective was to test a model of the relationships among adiposity, psychosocial factors and depression in adolescents. Method: In a population-based sample of 1127 boys and 1167 girls aged 13 and 16 years, a model of the relationships between adiposity, pressure to be thin, body dissatisfaction and depressive symptoms was tested using structural equation modeling. Results: Among girls, adiposity accounted for 62% of the total effect of depressive symptoms through its association with pressure to be thin and body dissatisfaction. Pressure to be thin was also uniquely related to depressive symptoms. Among boys, only body dissatisfaction was associated with depressive symptoms. Conclusion: Results support a relationship between adiposity, body satisfaction, pressure to be thin and depressive symptoms. Depressive symptoms should be assessed in obese adolescents, and interventions to prevent and treat obesity should incorporate elements targeting body dissatisfaction
