Lexical and semantic potential of emotionally expressive sentences in the tatar and French languages

The article deals with the problem of peculiarities of the expressive syntax in the Tatar and French languages. The expressive syntax has a large and varied inventory of linguistic resources among which an important place belongs to the lexical content of emotionally expressive sentences in the compared languages. The choice of specific lexical and syntactic means depends in each individual case on the situation, the subject of emotional evaluation itself, the relationship with the person or persons to whom the sentence is addressed. The expressive possibilities of the sentences appear brighter when they don't only characterize a phenomenon, but also transmit a special attitude of the subject of the speech towards it. The emotionally expressive sentences in the Tatar and French languages represent specialized syntactic means that are used to implement the category of emotional expression

Особенности внутренней позиции родителя у детей младшего школьного возраста

The paper examines the formation of the bases of the internal position of a parent in primary school-age children. The person’s internal position of a parent appears long before the birth of his/her own children; its components are formed in ontogenesis in accordance with the stages of the development of the parental sphere of personality.This study attempts the following: to disringuish components of the internal position of a parent; to explain the content of these components concerning primary school age; to define the criteria of the formation of the components of the primary internalposition of a parent in primary school children; to examine the factors influencing the development of the primary internal position of a parent in primary school children; to describe the differences in the formation of components of the primary internal position of a parent in boys and girls. The study involved 85 children aged 8 to 9 years (39 boys and 46 girls).An experiment, creating the conditions for video games, content analysis of children’s statements, and projective and questionnaire methods were methodological tools of the study. The authors evaluated characteristics of drawings, statements and actionsof children in the imaginary role of a parent. Most prominent criteria of the formation of the components of the internal position of a parent include the following: (a) the desire to have more than twochildren in the future; positive statements about the child, (b) use of support in emotionally significant situations, (c) use of endearment to a child. The obtained results also revealed a low level of the development of motivation (representation of the future family without children) and cognitive components of the internal position of a parent (formal statements about the child) in a significant number of junior schoolchildren.Статья посвящена изучению формирования основ внутренней позиции родителя у детей младшего школьного возраста. Делается предположение, что первичная внутренняя позиция родителя появляется задолго до появления собственных детей, а ее компоненты формируются в онтогенезе в соответствии с этапами становления родительской сферы личности.Выделяются компоненты внутренней позиции родителя и описывается их содержание применительно к младшему школьному возрасту. Определяются критерии сформированности компонентов первичной внутренней позиции родителя у младших школьников, изучаются факторы, влияющие на ее становление, а также описываются различия формирования компонентов у мальчиков и девочек.В исследовании приняли участие 85 детей в возрасте от 8 до 9 лет (39 мальчиков и 46 девочек). В качестве методического инструментария был применен эксперимент, в рамках которого создавались условия для режиссерской игры, контент-анализ детских высказываний, а также проективные и анкетныеметоды сбора данных. Оценивались характеристики рисунков, высказывания и действия детей в воображаемой роли родителя.В результате исследования были выявлены наиболее яркие критерии сформированности компонентов внутренней позиции родителя, а именно: желание иметь более двух детей в будущем, наличие положительных высказываний о ребенке, использование поддержки в эмоционально значимых ситуациях, использование ласкового обращения к ребенку. Полученные результаты также позволили выявить недостаточный уровень сформированности мотивационного (представление своей будущей семьи без детей)и когнитивного компонентов внутренней позиции родителя (формальный характер высказываний о ребенке) у значительной части младших школьников

Impact of landed property transformation on reproductive process in the agrarian process of regions

The article presents the results on land ownership transformation and its impact on the reproductive process in the agricultural sector of the Volga Region Federal District in conditions of the existing model. The analysis of the consequences of the land reform, of which 115,4 million hectares of agricultural lands were transferred into common share ownership in the form of land shares without defining the boundaries on the ground, was carried out. Availability of land shares which are not transformed into the land, fouls up and causes chaos and uncertainty in land relations, leading to the criminalization of the land market, speculative land transactions, hinders the development of the land turnover. The position of the Volga Region Federal District and its individual regions in regard to the national indexes that characterize agricultural production, factors of reproduction, is established. The conclusion concerning the low level of production profitability is made, and it hampers the extended reproduction and, consequently, the high demand for land for agricultural purposes in the future.peer-reviewe

Acrylated Eudragit® E PO as a novel polymeric excipient with enhanced mucoadhesive properties for application in nasal drug delivery

Eudragit® E PO (EPO) is a terpolymer based on N,N-dimethylaminoethyl methacrylate with methylmethacrylate and butylmethacrylate, produced by Evonik Industries AG as a pharmaceutical excipient. In this work, EPO was chemically modified through reaction with acryloyl chloride. The successful modification of EPO was confirmed by FTIR, NMR-spectroscopy, elemental and thermal analysis. The degree of acrylation was determined by permanganatometric titration. The slug mucosal irritation test was used to demonstrate non-irritant nature of EPO and its acrylated derivatives (AEPO). The mucoadhesive properties of EPO and AEPO were evaluated using freshly excised sheep nasal mucosa and it was demonstrated that acrylated polymers facilitated greater retention of sodium fluorescein on mucosal surfaces compared to solution mixture of this dye solution with EPO as well as free dye
