Convergence modelling in international integration associations

The article considers mathematical tools for modelling economic policy as a whole, as well as convergence in the field of labor, foreign economic activity, monetary and debt policy. Convergence was estimated using the convergence model, which characterizes the decrease in time spread in the levels of development of countries and regions, reflecting the negative relationship between economic growth rates and the initial level of development of countries and regions. The convergence was estimated by the coefficient of variation and by the dispersion-based model. To assess convergence, we used the Barro and Salai- Martin models, as well as the Baumol, Solow-Svan, and Quadrado-Rour models. The use of this mathematical toolkit allows to explore the presence and speed of convergence before and after joining international integration associations. The proposed mathematical modelling tools are recommended to be used in order to analyze convergence processes, study the dynamics of convergence or divergence, and also to adjust the directions and methods of state and regional economic policies of countries included in the integration association. © 2020 South Ural State University.

Anxiety, Suicidal Risk and Personal Characteristics of Medical Students

Background. The prevalence of anxiety, depression, personality traits and poor quality of life among medical students contributes to the formation of suicidal behaviorAims. To reveal the relationship between the severity of anxiety, hopelessness, personality traits and suicidal risk in students of Irkutsk State Medical University.Material and methods. The study included third-year students of the medical faculty of Irkutsk State Medical University (n = 61), average age – 19.7 ± 2.2 years. We used Spielberger – Khanin and Sheehan scales of self-assessment of the anxiety level, the personality questionnaire of Smisek – Mueller “Accent 2-90”, and Beck’s hopelessness scale.Results. According to the results of testing on the Spielberger – Khanin scale, the severity of reactive anxiety reached moderate values in 57.3 % of students, severe anxiety was found in 32.8 %, the absence of anxiety – in 9.8 %. Personal anxiety on the Spielberger – Khanin scale was characterized by moderate values in 52.5 % of cases, severe anxiety was found in 45.9 %, the absence of anxiety – in 1.6 %. Moderate and high values of reactive and personal anxiety were significantly more common compared to the students with no anxiety. According to the psychometric assessment of students using Sheehan scale, clinically expressed anxiety was observed in 47.5 % of cases, severe anxiety disorder – in 4.9 %, lack of anxiety – in 47.5 %. The personality traits of students with anxiety include hyperthymia, excitability, dysthymia, cyclothymia, introversion and exaltation.Нopelessness in students was detected in 27.9 % of cases (mild – in 16.4 %, moderate – in 9.8 %, severe – in 1.6 %). Тhe criterion of hopelessness was detected with pronounced situational and personal anxiety in comparison with moderately pronounced anxiety using Spielberger – Khanin scale (50 % and 39.3 % respectively); expressed and severe anxiety was detected in 51.7 % and 66.7 % of cases on the Sheehan scale.The personality traits of students with hopelessness included stuckness, pedantry (standard level and level above average); cyclothymia in the form of unstable mood; demonstrativeness; excitability (normative level); dysthymia in the form of attempts to deny difficulties; exaltation (average level); introverted personality direction.Conclusion. Determination of factors of suicidal risk is important in the prevention of suicidal behavior among medical students

Development of technology for obtaining electrodes based on copper wire using in the manufacture of solar modules

To optimize the technological process of manufacturing copper wire coated with solder of the POIN-52 grade, the optimal modes for the tinning temperature, linear velocity, diameter of the diamond die and flux were identified. It was found that the best wire tinning process is achieved when cleaning the surface of a copper wire by the method of electrochemical degreasing. The results of the tests showed that, in terms of mechanical and electrical parameters wire meets the require-ments for electrodes in the manufacture of solar modules. The results of climatic tests of solar modules  showed a high degree of reliability with a power loss of 0.86% and thermal cycling tests with a power loss of 0.4%, which is within tolerance

Noncommutative Moduli for Multi-Instantons

There exists a recursive algorithm for constructing BPST-type multi-instantons on commutative R^4. When deformed noncommutatively, however, it becomes difficult to write down non-singular instanton configurations with topological charge greater than one in explicit form. We circumvent this difficulty by allowing for the translational instanton moduli to become noncommutative as well. This makes possible the ADHM construction of 't Hooft multi-instanton solutions with everywhere self-dual field strengths on noncommutative R^4.Comment: 1+9 pages; v2: reference added, published versio

Современные западные концепции философии образования

Філософія освіти представлена широким колом концепцій та підходів. Основні можна умовно поділити на чотири групи у відповідності до «чистих» філософських систем: реалізму, ідеалізму, прагматизму, екзистенціалізму. Серед цілей філософії освіти виокремлюються: стимулюючі, аналітичні, наказові, дослідницькі. Цілі сучасної західної філософії освіти – це навчання для формування характеру, навчання для особистого зростання та успішності, навчання для розвитку та відточування естетичних схильностей. У межах американської філософії освіти сформувались три основні напрямки: емпіризм, раціоналізм, натуралізм. Згідно з підходом емпіристів, освіта у широкому сенсі є головним чинником, який впливає на людське існування, що стимулює людську діяльність, формує здібності та характер людини. Раціоналісти запровадили ідею «самовідчуження» як найбільш важливу для філософії освіти. «Самовідчуження» полягає у переході учня від однієї стадії навчання до іншої під керівництвом викладача, коли людський розум стає об’єктом власної уваги. На останній стадії інтелектуального розвитку відбувається відкриття універсалій, законів та принципів. Філософія освіти натуралістів полягає у тому, що висновки наукового дослідження природи треба розуміти не як свідоцтво істини, а як робочі гіпотези для подальшого глибокого дослідження. Наукові відкриття мають бути відкриттями для освіти. Філософія освіти – це міждисциплінарна наука, яка використовує підходи і знання методології низки суміжних наук. Освіта швидко реагує на зміни підходів та потреби ринку, тому сучасний філософсько-освітній дискурс має формуватися під впливом провідних тенденцій.The philosophy of education is represented by a wide range of concepts and approaches. The basic concepts of the philosophy of education can be divided into 4 groups according to the «pure» philosophical systems: realism, idealism, pragmatism, existentialism. Among the goals of the philosophy of education as an independent science are: stimulation, analysis, ordering, research. The delineation of the concept of education and the notion of school education are an important aspect in formulating the goals of the philosophy of education. A significant place in the process of finding and setting the goals of the philosophy of education is occupied by an alternative: discipline of mind or discipline of knowledge? It is worth paying attention to the goals of the modern Western philosophy of education: training for the formation of character, training for personal growth and success, training for the development and refinement of aesthetic predispositions, etc. Within the frameworks of the American philosophy of education, three main directions were formed: empiricism, rationalism, naturalism. According to the approach of the empiricists, education is the main factor, influencing human existence, which stimulates human activity, forms the person’s abilities and character. Rationalists introduced the idea of «self-alienation» as the most important for the philosophy of education. «Self-alienation» is a transition of a student from one stage of training to another one under the supervision of a teacher, when human mind becomes an object of his own attention. At the last stage of the student’s intellectual development, discovery of universals, laws and principles takes place. According to naturalists’ concept, the conclusions of scientific study of nature should be understood not as a testimony of truth, but as working hypotheses for further investigation. Scientific discoveries should be discoveries for education. Modern educational systems of the philosophy of education consist of religious and rational humanism, pragmatism, existentialism, and analytical philosophy. The general tendency of humanism is based on the critique of the generally accepted methods of school education, which are indifferent to the individual features of students. The philosophy of education is an interdisciplinary science that uses approaches and knowledge of the methodology of a number of related sciences. Education responds quickly to changes in market approaches and needs, and modern philosophical and educational discourse must be shaped by the influence of leading trends.Философия образования представлена широким кругом концепций и подходов. Основные концепции можно условно разделить на четыре группы в соответствии с «чистыми» философскими системами: реализм, идеализм, прагматизм, экзистенциализм. Среди целей философии образования выделяются: стимулирующие, аналитические, приказные, исследовательские. Цели современной западной философии образования – это обучение для формирования характера, обучение для личного роста и успешности, обучение для развития и оттачивания эстетических наклонностей. В рамках американской философии образования сформировались три основных направления: эмпиризм, рационализм, натурализм. Согласно подходу эмпиристов, образование в широком смысле является главным фактором, который влияет на человеческое существование, стимулирует человеческую деятельность, формирует способности и характер человека. Рационалисты ввели идею «самоотчуждения» как наиболее важную для философии образования. «Самоотчуждение» заключается в переходе ученика от одной стадии обучения к другой под руководством преподавателя, когда человеческий разум становится объектом собственного внимания. На последней стадии интеллектуального развития происходит открытие универсалий, законов и принципов. Философия образования натуралистов заключается в том, что выводы научного исследования природы надо понимать не как свидетельство истины, а как рабочие гипотезы для дальнейшего глубокого исследования. Научные открытия должны быть открытиями для образования. Философия образования – это междисциплинарная наука, которая использует подходы и знания методологии ряда смежных наук. Образование быстро реагирует на изменения подходов и потребности рынка, поэтому современный философско-образовательный дискурс должен формироваться под влиянием ведущих тенденций

Creation and study of emmer (<i>Triticum dicoccum</i>) × triticale hybrids

Triticale (× Triticosecale Wittmack) is of great interest as an insurance crop that can ensure the stability of the gross harvest of feed and food grains at a lower cost. In Western Siberia, only winter triticale varieties are cultivated, however, spring triticales are important for cultivation in regions not suitable for winter crops. To create spring varie ties with high yields and good grain quality, it is necessary to study and enrich the gene pool, identify donors of economically valuable traits. One of the possible ways to solve this problem can be through the production of secondary hexaploid triticales with the involvement of the tetraploid wild-growing species of emmer wheat Triticum dicoccum (Schrank) Schuebl. The aim of this work was to create and study hybrids of emmer T. dicoccum (Schrank) Schuebl. with hexaploid triticale using genomic in situ hybridization for staining of meiotic chromosomes and analysis of plant productivity elements in F4–F8. DT4, DT5, DT6 plants and the prebreeding F6 forms obtained from them – DT 4/168, DT 5/176 and DT 6/186 – were selected according to the characteristics of the productivity and the nature of the grain in the F4 hybrid population. The offspring of hybrids DT4 and DT5 and prebreeding forms DT 4/168 and DT 5/176 had an increased grain nature (over 750 g/l), but low productivity. The hybrid DT6 and the breeding form DT 6/186 obtained from it had high grain productivity (785 ± 41 and 822 ± 74 g/m2, respectively), but, like the paternal form of triticale UK 30/33, had a reduced nature of the grain. In F8 DT 6/186 plants, 7 homologous pairs of rye chromosomes and from 27 to 30 wheat chromosomes were found in meiosis, which indicates the presence of a complete rye genome and two wheat ААВВ genomes. Rye chromosomes showed stable formation of bivalents in contrast to wheat chromosomes, which caused the presence of aneuploids in plant populations. Thus, hexaploid forms DT 4/168 and DT 5/176 with well-made smooth grain and high grain size were obtained, which can be used as a source of this trait for selection of food-grade triticale. DT 6/186 is a promising form for further breeding in order to obtain high-yielding forms of triticale

The prevalence of cardiovascular risk factors and their structure among healthy women. The main results of the project «Three ages of women»

Background. Pathology of the cardiovascular system leads among the causes of mortality. Aim. To determine the presence and structure of cardiovascular risk factors in healthy women of various age groups for a further in-depth study of their correlation with the initial manifestations of common diseases. Methods. 408 healthy women took part in the study. The study was conducted among students and employees of MSUMD. All the women were questioned using a questionnaire specially created by the authors of the study. The questionnaire contained questions on identifying the main risk factors for cardiovascular diseases, nutritional characteristics, physical activity, the presence of bad habits and diseases, gynaecological status. Results. All the participants were divided into 4 groups. The 1st group included 157 volunteers of a young early reproductive age from 17 to 24 years. Women of an early and late reproductive age up to 45 years, depending on the presence of a history of childbirth, were divided into two groups: 113 women having given birth made up the 2nd group and 74 nulliparous peers formed the 3rd group. 64 postmenopausal women aged 45 to 66 years made up the 4th group. Complaints of shortness of breath and discomfort in the heart region without regard to physical activity (73% versus 36% of cases in the 1st group, p=0.001), insufficient physical activity (48%, p=0.001) were noted in women of the fourth group. 18.4% of respondents smoked cigarettes. Among chronic diseases, gastrointestinal diseases prevailed in 41.4% (n=169). The gynaecological status analysis revealed ovarian dysfunction in 26.8% of the respondents, premenstrual syndrome in 52% (group 1 volunteers), premature birth in 14.7% of volunteers, Cesarean section in 11.7% of women, birth complications in 15,4%, miscarriages in 11.4% of cases. In 28% of women of the 4th group with a surgical menopause, an increase in the body mass index, in the blood pressure, hot flashes and insomnia were noted (p=0.001). Conclusion. The presence of a large percentage of CVD risk factors in practically healthy women smoking, physical inactivity, obesity, hormonal disorders, pregnancy pathologies in young age groups requires an in-depth study in the identified risk groups
