Трансформация форм коммуникаций в современном университете при цифровой глобализации

Problem and goal. In the context of digital globalization traditional forms of communication at the university are forced to transform in order to meet educational objectives. However, the established practice of building communications in universities in new formats has revealed a number of problems of ineffective interaction between participants in the educational process. The article aims to identify the main features of the transformation of the forms of communication in distance learning at the university. Particular attention is paid to the conditions for the formation of an effective digital dialogue in the university-student-teacher triad. Materials and research methods. The study of the transformation of communication is considered from an economic, pedagogical, and philological (semiological) point of view. The economic approach includes consideration of resource constraints that prevent the development of various forms of communication in the educational space, and an assessment of the effectiveness of the communication process. The pedagogical approach allows to evaluate the technologies and formats of communication in online learning. The semiological approach is focused on the choice of techniques and schemes that are adequate to digital dialogue. The empirical research was carried out using the questionnaire. The survey involved 2-4-year students at the Ural Federal University named after the first President of Russia B. N. Yeltsin. Research results. In the 2020-2021 academic year, students were able to adapt to rapid inclusion in distance learning and the use of digital technologies, but half of the students prefer to return to the traditional format of education, 39% of students for a mixed (blended learning) format. It was found that if the verbal forms of communication when transferring the course content from the teacher to the students were not transformed taking into account the digital environment and online learning, then this could lead to unnecessary complexity for perception (according to 54.5% of respondents), the appearance of information noise, as a consequence, the appearance of discomfort (for 40% of the respondents) and attempts to avoid communication (for 18%). 52% of students indicated that their opinion about distance improved over time. Discussion and conclusions. The authors concluded that digital skills today mean more than digital literacy. In communication, it is important to develop new technologies, techniques and tools that are adequate to new educational and upbringing tasks. And in modern conditions, burdened by pandemic threats, other ways of digitalizing the university with the construction of effective communications are rather impossible. © 2021 LLC Ecological Help.

Образовательный потенциал подкастов в контексте формирования правовой культуры личности: новый формат и новые возможности медиасферы

Problem and goal. The development of new media, new modern IT technologies is also aimed at promoting legal content. New formats of the media sphere create new opportunities for dialogue on legal culture. The aim of the article is to study the educational potential of podcasting in the context of the formation of the human legal culture. Materials and research methods. Methodological approaches: cultural-historical approach for revealing personality as a product of cultural development, contextual approach for understanding the role of public opinion in personality development, competence-based approach for identifying the educational process in podcasts and selecting content for the construct "legal culture", personality-oriented approach for understanding self-developing and self-regulating personality in the process of forming a legal culture. An empirical study was carried out using the GetPodcast application on search queries for podcasts by words or phrases correlated with the theoretical construct "legal culture" in Russian and English, the time period for placing a podcast in the application was measured; the research is based on measuring, systematizing, comparing, summarizing, monitoring, interpreting the results of researching the audio content of podcasts. Research results. In 2020, on average, more than 2.5 million episodes on legal culture in English and more than 17.5 thousand in Russian were created in the media sphere. The authors calculated that the number of podcasts by one key concept in English is on average 234 times higher than the number of podcasts in Russian, which indicates the active spread of the new format of the media sphere throughout the world, while the demand for English-language podcasts is objectively higher. The growth rate of the number of podcasts in 2020 averages 66% and 58% for Russian-speaking and English-speaking podcasts, respectively, while the growth over the past six months is higher: 97% and 72%, respectively. This can be explained by the pandemic situation and forced self-isolation, as well as digital globalization and digital competencies of the population. Discussion and conclusion. The authors came to the conclusion that podcasts, as a new format of the media sphere, have educational potential, which must be used to a greater extent for the formation of the human legal culture. At the same time, the educational potential reveals the cognitive and epistemological interest of the listener. Podcasts form socially significant and personally necessary knowledge of a legal nature and meaning, which to a greater extent affects the condition and result of the process of forming human legal culture. © 2021 LLC Ecological Help.

Estimation of the integral toxicity of photocatalysts based on graphitic carbon nitride in a luminescent test

A ternary heterosystem consisting of crystalline graphitic carbon nitride, zinc oxide, and zinc sulfide (g-C3N4/ZnO/ZnS) was obtained by the one-stage decomposition of a mixture of thiourea and zinc acetate. The integral toxicity index of the resulting material was estimated in a luminescent test with a genetically modified Escherichia coli strain as a test object. The effect of quenching the luminescence of E. coli was noted both under exposure to UV radiation due to photocatalytic reactions on the surface of g-C3N4/ZnO/ZnS leading to the formation of highly oxidative radical ions interacting with cell membranes and without irradiation due to mechanical interactions with bacterial cells. At a 0.3 g/L concentration of g-C3N4/ZnO/ZnS in aqueous solution, the toxicity index T reached 75.6% under UV irradiation. In this case, an increase in the toxicity index T of the ternary heterosystem in a test concentration range from 0.1 to 0.3 g/L was 6 or 10–11% under UV radiation or without illumination, respectively, as compared with that of the pure graphite-like carbon nitride obtained under identical conditions

Формирование иммобилизованного наноструктурированного диоксида титана, обладающего антибактериальными свойствами

Nanostructured titanium dioxide (TiO2) coatings were formed on rigid aluminum and flexible fiberglass substrates using the sol-gel method modified by adding nano- and submicron TiO2 particles to the sol. The use of sols with such particles leads to the formation of a rough coating of agglomerates of nano- and submicron particles bonded with sol-gel synthesized TiO2. The antibacterial activity of the coatings was confirmed under irradiation with visible light from an LED source for 120 minutes. The most activity was demonstrated by all samples in relation to Staphylococcus aureus.Наноструктурированные покрытия из диоксида титана (TiO2) сформированы на жестких алюминиевых и гибких стекловолоконных подложках золь-гель методом, модифицированным включением в золь нано- и субмикронных частиц TiO2. Добавление в золь таких частиц приводит к образованию шероховатого покрытия из агломератов нано- и субмикронных частиц, скрепленных золь-гель синтезированным диоксидом титана. Антибак териаль ная активность полученных покрытий подтверждена в условиях облучения видимым светом светодиодного ис точника в течение 120 мин. Наибольшая активность продемонстрирована всеми образцами в отношении золотистого стафилококка

Development Of Molecular Markers In Redbay

Woody plant redbay (Persea borbonia) is a native species in South Carolina whose fine-grained wood is industrially valuable and whose fruits are a valuable food source for animals. However, laurel wilt disease has caused high levels of redbay death, threatening the sustainability of this economically and ecologically important woody plant species. Planting resistant clones of trees is the most promising approach to combat the disease. Large-scale development of molecular markers is imperative in molecular breeding for crop improvement. This project aimed to initiate a small-scale analysis of approximately 200 markers obtained from a shallow genome sequencing project of redbay. The markers that were being used targeted microsatellites, small tandem repeats of DNA that are highly mutable. Of the 213 markers being tested, polymerase chain reaction (PCR) amplification success rate was 94% among the 8 individuals that were used. A total of 160 markers had amplicons that were at least 100 base pairs in length. When fully characterized, these markers will be valuable in linkage map construction, molecular characterization of germplasm collections, and analysis of genetic diversity in redbay
