On the Flavor Dependence of the Mixed Quark-Gluon Condensate

The flavour dependence of the mixed quark-gluon condensate is studied through the analysis of correlators of the hybrid current $a_{\mu}=g\bar s\gamma_{\rho}\gamma_5 G_{\rho\mu}d$. The flavour symmetry breaking for this type of condensates is found to be less than that for the quark condensates. For the ratio of strange to nonstrange condensates we obtain \mbox{$R=0.95\pm 0.15$}. For the kaon coupling to the current $a_\mu$ we find $\delta'^2=(0.020\pm0.005)GeV^2$, which is an order of magnitude smaller than analogous chirally unsuppressed coupling.Comment: 8 pages, latex, two figures in a separate uuencoded file.

On Instanton Contributions to the tau Hadronic Width

Comparing the results of finite energy and Borel transformed sum rules for the difference of vector and axial vector current correlators we evaluate the instanton contributions to the $\tau$ hadronic width. In contrast to an explicit theoretical calculation we find that the instanton contributions to the $\tau$ hadronic width are much smaller than the standard nonperturbative corrections.Comment: 6 pages, Latex fil

Вдосконалення стратегії фінансового освіти для сталого розвитку

Introduction. Modern society has long agreed that financial education is one of the pillars of its sustainable development. In many countries, action plans were prepared, strategies developed, training courses were aimed at increasing the level of financial education, but after a few years it is again clear that the problem has not been solved, there are very few examples of success and it is not known whether these successes are the result of the above measures. The need of change the strategies in place today in financial education is slowly emerging. There is an urgent task of improving the strategy of financial education at the present stage of development of society. Aim and tasks. The purpose of this paper is to analyze the current financial education strategy on the example of one particular country – Georgia, its logical consequences and find the levers that will make this strategy more effective or outline the contours of the new strategy. Results. The results of the work done in Georgia in the field of financial education over the past six years were analyzed. Comparison of the stated goals and actual results of the current strategies of financial education is carried out. The study is based on the analysis of the determinants of financial behavior of human, the main postulates of behavioral economics. The methods of logical generalization, synthesis, analysis and deduction are widely used in the research to reveal the cause-and-effect relationship between mental models of thinking, financial education and financial stability of the individual. Also examined the development policy measures adopted by the World Bank. An assessment of their relevance for improving financial education is carried out. The importance of considering mental models of thinking in achieving goals set in various spheres of society was noticed. Also, as a result of the analysis, new approaches were identified that improve the strategy of financial education. Conclusions. Strategies need to be developed based on the mental models of the population of a particular country taking into account the psychological aspects that are significant for the members of a given community. It is necessary to process the information provided by the population, not only semantically, but also etymologically, within the framework of the measures outlined in the strategy and use categories in the context to which the society is more sensitive. More successful examples of financial education development policies need to be considered.Вступ. В сучасному суспільстві фінансова освіта є однією з основ його сталого розвитку. У багатьох країнах були підготовлені плани дій, розроблені стратегії, навчальні курси були спрямовані на підвищення рівня фінансової освіти, але через кілька років знову стає ясно, що проблема не вирішена, прикладів успіху дуже мало і ще невідомо, чи є ці успіхи результатом вищевказаних заходів. Потреба в зміні існуючих сьогодні стратегій фінансової освіти з'являється поступово. Постає актуальне завдання вдосконалення стратегії фінансової освіти на сучасному етапі розвитку суспільства. Мета і завдання. Мета даної статті - проаналізувати поточну стратегію фінансової освіти на прикладі Грузії, її логічні наслідки і знайти важелі, які зроблять цю стратегію більш ефективною або окреслити контури нової стратегії. Результати. Проаналізовано результати роботи, виконаної в Грузії в галузі фінансової освіти за останні шість років. Проведено порівняння заявлених цілей і фактичних результатів поточних стратегій фінансової освіти.  Дослідження ґрунтується на аналізі детермінант фінансової поведінки людини, основних постулатів поведінкової економіки. У дослідженні широко використовуються методи логічного узагальнення, синтезу, аналізу та дедукції для виявлення причинно-наслідкового зв'язку між ментальними моделями мислення, фінансовою освітою і фінансовою стійкістю особистості. Також були розглянуті заходи політики розвитку, прийняті Світовим банком. Проведено оцінку їх актуальності для підвищення фінансової освіти. Відзначено важливість врахування ментальних моделей мислення при досягненні цілей, поставлених в різних сферах життя суспільства. Також в результаті аналізу було виявлено нові підходи, що поліпшують стратегію фінансової освіти. Висновки. Стратегії необхідно розробляти на основі ментальних моделей населення конкретної країни з урахуванням психологічних аспектів, значущих для членів цієї спільноти. Необхідно обробляти інформацію, надану населенням, не тільки семантично, а й етимологічно, в рамках заходів, викладених в стратегії, і використовувати категорії в контексті, до якого суспільство більш чутливо. Необхідно розглянути більш успішні приклади політики розвитку фінансової освіти

Hierarchical Emulation & Data Assimilation into the Sediment Transport Model

AbstractSynthetic observations of the suspended sediment concentration in an idealised macro-tidal estuary are assimilated into the 3d sediment transport model. The assimilation scheme relies on fast and cheap surrogates of the complex model (called emulators) to update the model's state variables and its 2 parameters. A scenario with a hierarchically structured emulator is contrasted to the scenario with a more conventional non-hierarchical emulator. Numerical experiments indicate that for a given size of the ensemble an emulator which replicates a hierarchical structure of the model tends to provide a better approximation of that model. Improving the quality of the emulator translates into the improved quality of the assimilation products

STOMATOLOGICAL/DENTAL FEATURES OF VITAMIN D RESISTANT AND VITAMIN D DEPENDENT RICKETS

The aim of the study is an investigation of stomatological/dental characteristics at vitamin D resistant and vitamin D dependent rickets. Materials and methods: The study was based on the results obtained after investigation of 13 patients 0-18 of ages with D vitamin resistant rickets (I group) and 68 patients with D vitamin-dependent rickets (II group) and 61 children of control group. Physical development, dental status and biochemical features of the mentioned children have been studied. Methods of the study: anamnesis, clinical examination, X-ray examination, blood and urine biochemical analysis. Quantity data were compared according to - t (student) criteria and qualitative data – according to - F (fisher) criteria. Clinical data were processed with statistical programs package SPSS 22. Results: The incidence rates of insufficient physical development (physical retardation), body constitutional disorder, jaw shape, occlusion and teeth constitutional anomalies as well as delayed teeth eruption are significantly higher at vitamin D resistant rickets in comparison with vitamin D-dependent rickets and control group. The incidence rate of enamel hypoplasia in group of vitamin D resistant rickets is 0.69, vitamin D dependent group - 0.07(p>0.000) and control group – 0,03( p>0.000), respectively, the rate of periapical abscesses with canal orifice – in group of vitamin D-resistant rickets equals to 0.31, vitamin D-dependent group – 0.06(p=0.054), and control group - 0.10(p=0.0457), respectively, which is significantly higher in comparison with the dependent rickets and control groups. Among the children with vitamin D resistant rickets, average caries intensity (DMF) index and average PMA index p>0.05 are reliably higher in comparison with vitamin D dependent rickets. Tubular phosphate reabsorption reveals positive correlation with DMF index – r =0.57, p = 0.0380; PMA index - r=0.84, p=0.0003; reduction of tubular phosphate reabsorption correlates with caries r=0.6770, p=0.0110; pulpitis r =0.6770, p =0.0110; periodontitis r=0.6770, p=0.0110. Conclusion: At vitamin D resistant rickets the dental anomalies, being in correlation with metabolic disorder, occur
