Development of the concept language in the minds of pupils: analysis of school textbooks

Knowledge of a person about the world make a system of concepts, while language is coding of the language world picture by language means. Conceptual approach stimulates development of a more detailed world picture in the mind of a person. The Russian language takes an important place in the system of education. Analysis of the concept “language” in school textbooks revealed both positive and negative features.Знания человека о мире представляют собой систему определенных концептов, а язык – это кодирование языковыми средствами картины мира. Поэтому концептуальный подход способствует формированию наиболее полной картины мира в языковом сознании и становлению индивида как личности. Таким образом, русский язык в системе образования занимает особое место. Анализ концепта «язык» в школьных учебниках выявил как положительные, так и отрицательные моменты

РОЛЬ КОМІСІЙНИХ НАДХОДЖЕНЬ У ФОРМУВАННІ ДОХОДІВ КОМЕРЦІЙНОГО БАНКУ

The expanding of banking services spectrum allows the redistributing of financial risks, the reduce of their negative impact on the efficiency of the commercial bank and creating of new revenue channels. According to this process, the issues of increasing the volume of provision and growth of commission receipts proportion in the general structure of revenues of banking institutions are actualized. In addition, commission receipts more stable than interest, but their not associated with the risk of losing the value of invested assets (except for the guarantee operations). That is why the article is devoted to determination of the effect of impact the volume of commission of banks on the total amount of their income. The research is based on the study of the relationship between the indicators in deal with cubic one-factor regression model.  It would be the basic for a diversification of the portfolio of banking services to protect the bank from crises at the financial market and for adoption of effective management decisions. As a result, the significant influence of the growth of commission receipts on the general level of income of commercial banks. This is evidenced by the computed the correlation coefficient (its value is 0.96 and shows the close relationship between the volume of revenues and volumes of their commission receipts), coefficient of determìnacìï, which is 0.91 (that is change the bank`s income on 91.0% depends on  the change in the volume of commission receipts of commercial banks) and strong elasticity ECI(I > 1 (the increase of commission receipts of banks in Ukraine has a significant impact on the growth of their  total). According that it is possible to conclude that the role of commissions in the general process of generating revenues of the bank is increased.Розширення спектра банківських послуг, що надаються клієнтам, дозволяє перерозподілити фінансові ризики, знижуючи рівень їхнього негативного впливу на ефективність роботи банку, сформувати нові канали надходження доходів. За таких умов актуалізуються питання підвищення обсягів надання і зростання питомої ваги комісійних надходжень у загальній структурі доходів банківських установ. Крім того, комісійні надходження стабільніші, ніж процентні, а їх отримання майже не пов’язане з ризиком втрати вартості вкладених активів (крім гарантійних операцій). Досліджено вплив зміни обсягу комісійних надходжень банків на загальний рівень доходів на основі вивчення зв’язку між зазначеними показниками через використання однофакторної регресійної моделі, що в подальшому надасть можливість диверсифікації портфеля банківських послуг для захисту банків від кризових явищ на фінансовому ринку й ухвалення ефективних управлінських рішень. У результаті виявлено наявність значного впливу зростання обсягу комісійних надходжень на загальний рівень доходів комерційних банків. Про це свідчить розраховані коефіцієнт кореляції (його значення дорівнює 0,96 і показує тісний зв’язок між обсягом доходів банків та обсягами їхніх комісійних надходжень), коефіцієнт детермінації, що становить 0,91 (тобто зміна доходів банків на 91,0 % залежить від зміни обсягів комісійних надходжень комерційних банків) і висока еластичність ECI(I) > 1 (приріст комісійних надходжень банків в Україні має значний вплив на зростання загального рівня дохідності). Це дало змогу зробити висновок про підвищення ролі комісійних надходжень у загальному процесі формування доходів банку

Light-Induced Atomic Desorption for loading a Sodium Magneto-Optical Trap

We report studies of photon-stimulated desorption (PSD), also known as light-induced atomic desorption(LIAD), of sodium atoms from a vacuum cell glass surface used for loading a magneto-optical trap (MOT). Fluorescence detection was used to record the trapped atom number and the desorption rate. We observed a steep wavelength dependence of the desorption process above 2.6 eV photon energy, a result significant for estimations of sodium vapor density in the lunar atmosphere. Our data fit well to a simple model for the loading of the MOT dependent only on the sodium desorption rate and residual gas density. Up to 3.7x10^7 Na atoms were confined under ultra-high vacuum conditions, creating promising loading conditions for a vapor cell based atomic Bose-Einstein condensate of sodium.Comment: Sodium LIAD loaded MOT, 7 pages, 5 figures.

The chiral Anomalous Hall effect in re-entrant AuFe alloys

The Hall effect has been studied in a series of AuFe samples in the re-entrant concentration range, as well as in part of the spin glass range. An anomalous Hall contribution linked to the tilting of the local spins can be identified, confirming theoretical predictions of a novel topological Hall term induced when chirality is present. This effect can be understood in terms of Aharonov-Bohm-like intrinsic current loops arising from successive scatterings by canted local spins. The experimental measurements indicate that the chiral signal persists, meaning scattering within the nanoscopic loops remains coherent, up to temperatures of the order of 150 K.Comment: 7 pages, 11 eps figures Published version.

Conductivity, weak ferromagnetism and charge instability in α−MnS\alpha-MnS single crystal

The temperature dependence of resistivity, magnetization and electron-spin resonance of the $\alpha- MnS$ single crystal were measured in temperature range of $5 K < T < 550 K$. Magnetization hysteresis in applied magnetic field up to 0.7 T at $T=5 K, 77 K, 300 K$, irreversible temperature behavior of magnetization and resistivity were found . The obtained data were explained in terms of degenerate tight binding model using random phase approximation. The contribution of holes in $t_{2g}$ and $e_g$ bands of manganese ions to the conductivity, optical absorbtion spectra and charge instability in $\alpha -MnS$ were studied. Charge susceptibility maxima resulted from the competition of the on-site Coulomb interaction between the holes in different orbitals and small hybridization of sub-bands were calculated at $T=160 K, 250 K, 475 K$.Comment: 6 pages, 12 figure

Systematic Approach to Teaching Academic Writing: Practical Experience

The article describes the practical implementation of an experimental model for teaching academic writing to non-linguistic students of humanities at three levels of higher education. Improving the quality of domestic scientific publications submitted to high-ranking journals requires new effective pedagogical technologies. Theory and methodology analysis, as well as empirical observations show that the problems faced by Russian-speaking authors of academic texts can be divided into two categories: strong Russian accent that creates the language barrier and hinders understanding, and flawed academic style that leads to the cross-cultural academic barrier. The described ten-year study involved 25 students of Petrozavodsk State University, aged 17 to 28, who subsequently completed bachelor’s, master’s and postgraduate programs. At each of the three stages, the participants completed a set of tasks aimed at consistent and systematic formation of academic writing competence through writing abstracts (bachelors), conference proceedings (master’s students) and full-text academic articles (postgraduate students). To collect and process the data, the researchers used an open-ended questionnaire, the observation method, expert assessment, and descriptive statistics. The study results showed that the systematic approach helps to effectively eliminate structural and stylistic writing problems over the course of studies. However, the difficulties associated with the manifestation of the Russian accent in written English-language academic discourse are more resistant. The authors make the conclusion that the systematic development of academic writing skills in English will help to overcome obstacles for the internationalization of Russian science

Radial HI Profiles at the Periphery of Galactic Disks: The Role of Ionizing Background Radiation

Observations of neutral hydrogen in spiral galaxies reveal a sharp cutoff in the radial density profile at some distance from the center. Using 22 galaxies with known HI distributions as an example, we discuss the question of whether this effect can be associated exclusively with external ionizing radiation, as is commonly assumed. We show that before the surface density reaches $\sigma_{\textrm{HI}}\le 0.5 {\cal M}_\odot/{\textrm {pc}}^2$(the same for galaxies of different types), it is hard to expect the gas to be fully ionized by background radiation. For two of 13 galaxies with a sharp drop in the HI profile, the "steepening" can actually be caused by ionization. At the same time, for the remaining galaxies, the observed cutoff in the radial HI profile is closer to the center than if it was a consequence of ionization by background radiation and, therefore, it should be caused by other factors.Comment: 15 pages, 6 figure

Structural-chemical features and morphology of glauconites in sedimentary iron ore of Bakchar prospect (Western Siberia)

The research embraces the investigation results of glauconites in Bakchar iron ore occurrences to evaluate the potential diversified commercial application of this mineral. The following lab methods were used to analyze the morphology, chemical composition and structure of glauconites: granulometric analysis, optical microscopy, electron microscopy, X-ray fluorescence analysis, atomic arc-emission analysis and infrared spectroscopy. Glauconite was classified according to morphology and grain color and chemical composition and some specific characteristics were also determined (relative content of absorbed water, random distribution of smectite flakes within the grain structures). The research results showed that pistacho-green glauconite grains are less subjected to alteration than greenish-yellow grains due to the content of potassium, iron, absorbed water and organic impurities
