On local strength of a spherical vessel with pits distributed along the equator

The effect of multiple shallow corrosion pits on the strength of a spherical vessel subjected to internal pressure is studied. The pits are considered both randomly and evenly distributed along the equator on the outer surface of the vessel. The dependencies of the stress concentration factor on the number of the pits are compared for linearly elastic and elastic-plastic material with hardening. The behavior of the vessels made of elastic and elastoplastic materials turned out to be qualitatively different. The approximation of periodic pits arrangement is discussed

Close Gap Test Strategies for Students with Severe Speech Impairment

Introduction. The level of formedness of text competence at secondary school in the aspect of understanding the text’s factual information ensures the successful grasping of the learning content. The purpose of the research was to identify the specifics of the functioning of linear deployment mechanisms and probabilistic forecasting among learners of 5–10th grade (form) with specific language impairment. Материалы и методы. The modified close gap test method was used as the main research method at the level of the ascertaining experiment. The results of the close gap tests, filled by learners, were exposed to quantitative and qualitative analysis. The research was conducted by applying theoretical (interpretive) and empirical (ascertaining experiment based on author’s method) methods. The analytical stage involved the use of the method of correlation analysis, the mathematical processing was carried out with the help of one-way analysis of variance (ANOVA). Results. Analysis of experimental data helped determine the close gap test strategies in adolescent students with specific language impairment. The qualitative and quantitative analysis of studentsʼ work was applied to determine three main groups of strategies for linear deployment and probabilistic forecasting: strategies for establishing semantic links at the level of the lexical component, a strategy for establishing links at the level of associations, and no strategy. Furthermore, the analysis of substitutes with regard to their compliance with grammatical requirements revealed the following typology of manifestations of agrammatism: the use of an inadequate part of speech, deficiencies of grammatical presentation in phrases, non-compliance of the grammatical form of the substitute with the requirements for the grammatical design of the sentence. Correlation analysis was applied to establish links between different types of close gap test strategies used by adolescents with specific language impairment, as well as their relationship with the levels of understanding the factual content of the text. Discussion and Conclusion. The results obtained contribute to the development of developmental psycholinguistics, special pedagogy, speech therapy and school methods of speech development

Assessment of Imagination in Senior Preschoolers by Educators

Background. The relevance of this study is determined by the importance of timely assessment and development of imagination in preschoolers for their harmonious development and further successful schooling. Objective. The aim of the study was to develop a questionnaire for kindergarteners aimed at assessing the imagination in preschoolers. Methods. As a part of this study, a questionnaire to assess the characteristics of imagination in preschoolers was developed, which included 22 statements about children behavior, which teachers had to evaluate on a 5-point scale. Also, with a part of the sample, the “Complete the Drawing” technique was carried out. Sample. In the study, educators assessed 553 pupils of senior groups (M = 65.3; SD = 4.03 months; 48.1% of boys) attending kindergartens in 4 regions of Russia (37.1% of children from Moscow, 32.6% from the Tatarstan Republic, 22.3% from the Sakha Republic, 9.1% from the Perm Region) Results. As a result of the statistical analysis, a three-factor structure of the created questionnaire was revealed. It was found that educators rate the level of imagination development higher in girls than in boys. Comparison of teachers' assessments with the results of children's imagination assessment using the “Complete the Drawing” technique showed the relationship with such parameters of drawings as flexibility, originality and elaboration. Conclusion. The study showed the reliability of the developed questionnaire for educators, which indicates the possibility of its use in monitoring the development of modern senior preschoolers

Cognitive methods of processing social information on the Internet in adolescence

Background. Within the conditions of information socialization that is transforming communication and placing high demands on the ability of the individual to search, select, critically comprehend social information for decision-making and carrying out moral choices, a new social situation has developed. The research of the relationship between cognitive methods of processing social information on the Internet and shaping the worldview and ideas about the moral regulation in adolescents makes it possible to study the patterns of personality development in the unity of the cognitive and value-moral spheres. The Objective of the research is to identify cognitive methods of processing social information on the Internet as a factor of developing a picture of the world in adolescent users with varying degrees of involvement and the risk of Internet addiction and moral regulation of relationship between them. Hypothesis. Cognitive methods of processing information on the Internet are connected with the level of Internet addiction - a high level of Internet addiction corresponds to the low efficiency of cognitive methods of processing information. These methods influence the emerging system of major beliefs and worldview characteristics, and level of sensitivity to situations of moral choice. Design. The author’s method of assessing social information on the Internet based on Crick and Dodge model (1994), Chen method for diagnosing Internet-addictive behaviour, «The scale of basic beliefs of the person» of R. Yanoff-Bullman (Kalmykova , Padun, 2002), and the author’s method of assessing moral aspects were used. The study involved 84 adolescents from 13 to 18 years (46% males and 54% females). Results. A comparative analysis of the effectiveness of cognitive processing cycles was conducted and gender differences were revealed. The relationship between Internet addiction and the effectiveness of cognitive processing methods of information on the Internet is verified. The significance of interpretation, behaviour assessment and the ability to construct social adaptive behaviour in communication to shape the major beliefs and moral attitude in adolescence are shown. Conclusion. There are differences in the effectiveness of cognitive processing cycles of information. High efficiency of short-term, long-term, medium-term perspectives and behavioural responses and the ability to choose adequate social behavior corresponds to a relatively low productivity of interpretation. Internet addiction is interrelated with the low productivity of interpretation. Moral attitude is mediated by the age features of adolescent self-awareness and is related to the effectiveness of information interpretation, the evaluation of behavioural consequences and the choice of appropriate ways of social interaction

New Generation of Foreign Language Textbook as Reflecting Current Challenges

The article deals with the conception of the new generation foreign language textbook reflecting contemporary challenges in the sphere of higher education. These are integration processes involving globalization and localization, interdisciplinary tendencies, interactive collaborative learning methods, digital technologies, visualization practices. Modern textbook is shown to have become a pedagogical platform that ensures the compatibility of methodological conditions for interconnected learning of receptive and productive types of speech activity: reading, listening, speaking and writing. Integrative approach in the textbook composition is illustrated by inclusion of Russian-English translation exercises and integrated assignments involving reading, watching a video and writing. Interdisciplinary principle is exemplified by the technical English manual combining scientific, technical, and intercultural components variation. Interactive learning methods are shown to trigger teamwork performed in the classroom or in independent mode with the use of digital technologies. It is indicated that numerous computer-assisted language learning tasks are becoming more widely used in modern textbooks, especially those aimed at the content visualization. Some of the visualizing elements, like word clouds, mental maps and info posters, are considered in detail accentuating their didactic values

Vocational guidance in social volunteering

The paper discusses the possibilities and limitations of vocational guidance in the social volunteering system. The essence of volunteer work is closely related with assistance to desperate people in searching for the meaning of living, often coinciding with labour activity that are deemed in terms of “the main matter of life” and “the leading activity”. For adolescents, it is the choice of career, and for adults, it is the work proper (i.e. an essential condition for personal self-realization). The problem of “forced volunteering” for experts in vocational guidance also means that they often have to work voluntarily and unselfishly outside the official guidelines. To clarify the terms «volunteer» and «a person in desperate need of help» the study used the method of analyzing the documents, e.g. the Regulations on Social Volunteering, the generalization of psychological sources, the initial survey of university students as active supporters of the volunteer movement, On the essence of volunteering and the place of career guidance in selfless social work. Vocational guidance is not excluded from the general system of volunteerism, but has an insufficiently defined status and low popularity among participants in social volunteering. Also, the problem of «forced volunteering» of experts in career counseling, which often requires voluntary and unselfish performance of quality work outside the framework of official instructions, is also indicated. Simultaneously, positive aspects of such disinterested career initiatives are noted, in particular, less control by the official inspectors (or customers) and, accordingly, greater freedom of creativity than when someone else does the work

The voluntariness in the preschool age: a comparative analysis of various approaches and diagnostic tools

MMost modern psychologists who deal with preschool age emphasize the development of executive functions as one of the most important factors in this age. The paper compares two most important and common approaches to disclosing and diagnosing voluntariness in the preschool age: the model of executive functions «unity with diversity» of A. Miyake and the skills theory of L.A. Venger. The model of the executive functions considers three main components of executive functions: working memory; flexibility of attention or switching; restraining control. The basis of cognitive abilities theory is the concept of cultural facilities (sensory standards, visual models, etc.) that are being developed throughout the preschool period. In accordance with these two diagnostic complexes were drawn up, aimed at diagnosing voluntariness in preschool years. The study involved 48 children aged 5-6 years, kindergarten students (24 girls and 24 boys) conducted in Moscow, Russia. The results showed that despite a variety of theoretical approaches to early childhood and voluntariness they reverberate the same reality. The most revealing methods (the results of which you can predict the eventual consequences) were elaborated: the method of «Inhibition» (subtest of neuropsychological diagnostic complex techniques NEPSY-II, Korkman et al, 2007) in the case of A. Miyake model, and methods of «Schematization» in the abilities theory of L.A. Venger (Venger, Kholmovskaya, 1978)

Difference in Executive Functions Development Level between Two Groups: Preschool Children Who Took Extra Music Classes in Art Schools and Children Who Took Only General Music and Dance Classes Offered by Preschools

Previous studies have shown that there is a positive correlation between attending music classes regularly and the development of executive functions. This paper discusses the results of a pilot study dedicated to determining the difference in the level of development of the components of executive functions (inhibitory control, cognitive flexibility, and working memory), between 5–6-year-old children taking extra music classes, and children who participated only in general music and dance education in kindergarten. A total of 94 senior preschoolers from Moscow kindergartens took part in the study. Children were selected into an “extra music lessons” group and a “general preschool music and dance lessons” group based on the results of a questionnaire on supplementary education, which was filled in by parents prior to the research starting. The respondents from the “extra music and dance lessons” group attended music classes in art schools at least two times a week, both in individual and group formats. The current study revealed that children attending regular extra music classes had a higher level of inhibitory control, audio–verbal working memory, cognitive flexibility, and general coordination of the development of all executive functions. The obtained results support the value of regular extra music classes at preschool age. Moreover, this pilot study allows us to articulate the recommendations for further research in this direction
