Authors:   Ural Federal University, Abramova Sofya Borisovna , Antonova Natalya Leonidovna ,   Ural Federal University
Published: December 2020

The paper examines online learning as an innovative practice, the frequency of which has increased dramatically during the pandemic. This caused significant changes in students’ assessment and perception of online technologies, and also caused the formation of new fears in the context of digitalization of education. A comparative analysis of two stages of the survey of Ural Federal University students (2019, n = 150 and 2020, n = 70) made it possible to demonstrate changes in the structure of motives for refusing to use online education and in highlighting its significant shortcomings against the background of the pandemic. The main areas of growth of social fears of students in online learning are highlighted: social isolation, changes in requirements for the students themselves, the consequences of a sedentary lifestyle, a decrease in health potential, etc. The main field of activity of young people – education – becomes a source of growth of social fears and anxiety.

Authors:   Russian Presidential Academy  of National Economy  and Public Administration, Mudarisov Ainur Alikovich , Lytkina Ksenia Alexandrovna ,   Russian Presidential Academy  of National Economy  and Public Administration
Published: December 2020

The paper compares two approaches used in evaluating and predicting the managerial effectiveness of a Manager. The work compares the widespread competence approach and a relatively new approach based on a combined analysis of the meanings, values, goals, and motives as ideological manifestations of the Manager. A number of explanations is offered for the popularity of the competence approach as the most convenient for developing assessment tools, including digital ones. The paper describes the methodological vulnerability of the competence approach, where the personality is still considered only as a set of individual traits, characteristics and qualities. The author shows the difference in the interpretation of the concept of “competence” that exists in the research, consulting, management and HR communities, which blurs the boundaries of this definition. The alternative approach to analyzing and predicting the effectiveness of the subject of management activity is justified, based on identifying the features of the Manager's worldview, where personal and professional motives, needs, and claims are interpenetrating. Some variants of digital methods for studying the value-semantic sphere and features of the professional Outlook of managers are developed. The work reveals the possibilities of theoretical justification for evaluating and predicting the managerial effectiveness of a Manager, which are based on the analysis of his worldview.

Authors:   Scientific Research Institute  of National Schools of the Republic of Sakha (Yakutia), Vasilyeva Nadezhda Nikolayevna ,   North-Eastern Federal University, Nikiforova Yevdokiya Pavlovna ,   North-Eastern Federal University
Published: December 2020

The paper reveals the problems of the formation of communicative competence at the syntactic level in students of primary school age of a Yakut school. The importance of the native language in teaching Russian and foreign languages is emphasised. Speech syntax is considered to be the indicator of the communicative and cognitive potential of primary school children. The results of experiments showed that oral and unprepared written speech in the native language on a given topic do not differ from each other in quality and content. It was revealed that the prepared written speech activates vocabulary of students, while the number of words and common simple sentences in the text increases, but syntactic constructions do not show significant changes in quality. In this regard, the authors emphasise the need to develop and implement a minimum of syntactic structures in the native (Yakut) language for primary school students.

Authors:   Northeastern Federal University, Dishkant Elena Valerievna , Parnikova Anna Ivanovna ,   Secondary General Education School No.15
Published: December 2020

The current socio-educational situation, which has recently developed in the general education schools of our country, is associated with a large inflow of migrants and the realization of their right to education. The relevance of the research topic is due to the need to create a systematic approach in the education of schoolchildren, who do not have the Russian language as their native one. Moreover, it is due to the development of an intensive methodology for the formation of cultural and communication competence in children of migrants. The paper presents the author’s elective course “Russian Language Without Borders” for students of the sixth grade of secondary school, which is aimed at improving the socio-cultural and educational-cognitive competence of students. A lesson on the development of students’ speech, based on the novel by The Yakut author Viktoria Gabysheva “Karina. 12 days in the taiga” has been demonstrated. Based on the experiment conducted among the students of the 6th grade of secondary school No. 15 in Yakutsk, the authors came to the conclusion that it is essential to apply a systematic approach in the formation of the linguistic and socio-cultural competence of students.

Published: December 2020

Ageing of population is a global trend that requires modernization of existing institutions to create conditions for a decent and proactive old age. The present study examines the analysis of foreign practices in involving senior citizens in working life. Based on the systematization of foreign research there were identified: main problems of employment of retired persons, as well as the most popular tools and technologies for involving and keeping them in the labour sphere. The study places emphasis on only on the development of government programs and initiatives regarding the considered socio-demographic group, but also on the efficient tools of solving the raised problem at organizational level. The authors note that only a comprehensive approach and the creation of interconnected institutions can ensure the development of new mechanisms of employment relations at labour market and the demand for elderly workers. It is highlighted that the effectiveness of introducing foreign technologies and tools in Russian management depends on the following: quality of preliminary analysis of their demand; their adaptation taking into account existing resource limitations (concerning financial and management aspects) of Russian companies and the established management practices; development of a new culture of ageing.
Issues of Teaching English Language to Adults
Authors:   Center of Intellectual Development “Memory Up”, Vakhrusheva Daria Aleksandrovna
Published: December 2020

This study is devoted to the consideration of the issues of teaching English to adult learners. It is noted that teaching English to adults today is in great demand, due to the world integration aspirations of our country, which cannot be realized when the majority of the population does not have foreign language speech skills and abilities for free participation in international communication. However, adult education differs significantly from the specifics of teaching a foreign language to schoolchildren and students, which provokes a number of problems. These problems impede the acquisition of English by adults, which, as a rule, they need for professional activities that involve the implementation of foreign language communication. The analysis carried out in this study helped to identify the problems that need to be overcome to build an effective system of teaching English to adults. In addition, a number of psychological and pedagogical conditions that contribute to the effective teaching of the English language to adults and the formation of their foreign language communicative competence were formulated.

Authors:   Stavropol branch of the Krasnodar University  of the Ministry of Internal Affairs of Russia, Nesterenko Andrei Vladimirovich
Published: December 2020

The paper discusses the features of socialisation of cadets – graduates of educational institutions of the Ministry of internal Affairs of Russia in the conditions of their service in police units. The author comes to the conclusion that for successful socialisation of a cadet who graduated from the school of the MIA of Russia, he must pass certain stages of formation as a practical police officer in Internal Affairs agencies, namely: to acquire experience in performing professional tasks in the police force; to become aware of their belonging to Internal Affairs bodies; adapt to the performance of official duties of an employee of the Internal Affairs bodies, taking into account personal needs. The rapid transformation of a cadet into a practical police officer during the above-mentioned stages of formation is facilitated by the impact on him of both mandatory norms in force in the Internal Affairs bodies, which provide for strict compliance with orders of higher management, and social norms aimed at meeting personal needs in civil society, provided that the police observe the legitimacy of their implementation.

“Les voy a echar de menos cuando regrese a los Estados Unidos”: adquisición de la variación dialectal por aprendientes de español en un contexto de inmersión
Authors: Salgado-Robles Francisco , Ibarra Carlos Enrique
Published: December 2020

En general se cree que estudiar en el extranjero es una de las maneras más eficientes y exitosas para adquirir el dominio de una lengua extranjera (L2), ya que los aprendientes se encuentran en situaciones en las que usan la lengua diariamente e interactúan con hablantes nativos. Después de una gran cantidad de investigación centrada en los resultados de la L2 de los programas de inmersión en español, muchas preguntas relativas a la adquisición de los patrones de la variación lingüística común a una comunidad en particular en un contexto de inmersión siguen sin respuesta. Este artículo explora hasta qué grado un grupo de aprendientes de español adquirieren estructuras variables del lenguaje, específicamente, el fenómeno del leísmo, mientras participan en un programa de inmersión de cinco meses en Valladolid (España). Los resultados sugieren que los aprendientes en un contexto de inmersión, de hecho, estimulan la conciencia de las formas no convencionales de la lengua meta, que son, hasta cierto punto, incorporadas a su competencia sociolingüística. En resumen, este estudio contribuye a ampliar un mayor conocimiento sobre el desarrollo de la competencia lingüística de la interlengua durante una estancia en el extranjero, así como a llenar un vacío en el nuevo capítulo de los estudios sobre la adquisición de la variación dialectal.

Consecuencias éticas de la inclusión del terrorismo en Días contados de Imanol Uribe
Authors: Martín de Marcos Gonzalo
Published: December 2020

El dilema de matar o no matar constituye el centro del drama de Días contados, película dirigida por Imanol Uribe. Como adaptación de la novela homónima del novelista Juan Madrid, el director transformó al fotógrafo de la obra literaria en un terrorista, aunque supo aprovechar, como referencia crítica con su conducta, el friso de marginación de un Madrid degradado durante la primera mitad de la década de 1990. Sujeto a un conflicto que trasciende lo personal, el protagonista, en su relación con una joven prostituta, exhibe contradicciones morales que surgen de su pertenencia a ETA. Mediante dispositivos como la heroificación irónica o la humanización, se generan tensiones que lo conducirán a una encrucijada cuya resolución acredita un juicio sobre el terror. La victimización, el sacrificio y la redención también forman parte de un filme en el que, más allá de la apariencia, y pese a la mayoritaria interpretación académica, el terrorismo desempeña un papel en el primer plano de la historia, sin cuya consideración es imposible comprender las tragedias individuales.

O "Discorso" de Paleotti e o desejo por uma teoria Tridentina da imagem
Authors: Habib de Salles Abreu Clara
Published: December 2020

Qual era a real importância que a Igreja, no contexto das reformas religiosas do século XVI, dava ao controle sobre as imagens na Europa Católica? O artigo em questão pretende investigar, a partir da análise do Discorso intorno alle immagini sacre e profane do Arcebispo de Bolonha Gabriele Paleotti, uma relação entre teoria e prática das artes no contexto do Concílio de Trento. Trata-se de questionar qual é a real distância existente entre o discurso teórico, intelectualizado, proferido pelos representantes da Igreja e tratadistas da arte (desejosos por uma normativa) e a efetiva prática da arte, que, por vezes, escapava a essa normativa.

Regulación jurídica del agua embotellada y del arsénico en la provincia de Buenos Aires, Argentina
Authors: Minaverry Clara , Cáceres Verónica
Published: December 2020

El presente trabajo en primer lugar, presentará una caracterización del mercado de agua embotellada en Argentina y de su institucionalidad. En segundo lugar, se expondrá un debate actualizado sobre los niveles de arsénico, la situación de las empresas vinculadas con el comercio de agua embotellada, la normativa vigente, la percepción de la población respecto al agua que se distribuye en las redes y el agua embotellada, y, por último, se presentarán una serie de conclusiones. Es posible concluir que las empresas que comercializan agua embotellada no están obligadas a informar el componente de arsénico y que esto podría interferir con los derechos constitucionales de los consumidores. Además, la regulación jurídica de la calidad del agua presenta lineamientos contradictorios e insuficientes y la población del Noreste de la Provincia de Buenos Aires en su mayoría afirma que el agua embotellada presenta una calidad superior que la de red condicionando su consumo.

Esterification and deacidification of waste cooking oil using alkali neutralization for biodiesel production using corncob ash as an alternative base catalyst was carried out. This study aimed to attainone of the desired transesterification conditionsby reducing free fatty acids content of waste cooking oil. Esterification was carried out by reacting waste cooking oil and methanol with certain volume ratio and acid catalyst (H2SO4) at 50oC for 4 hours. Deacidification was carried out by adding 0.5 N NaOH solution (15% excess alkali) at 60oC for 30 minutes. Esterification of waste cooking oil using acid catalyst before transesterification with corn cobs ash catalyst significantly increased the efficiency of free fatty acid conversion (92.69%) under volume ratio of 25% methanol /oil and 0.5% acid catalyst for 4 hours reaction. Deacidification of esterified oil with FFA content of 2.29 mg KOH /g oil through alkali neutralization at 55oC using alkaline content of 0.8 N reduces free fatty acid content to 0.47 mg KOH /g oil. Transesterification results showed that biodiesel component of waste cooking oil was dominated by polyunsaturated fatty acids (linoleic acid / C18-2), monounsaturated fatty acids (palmitic acid / C16-1 and oleic acid / C18-1) and saturated acids (palmitic / C16-0 and stearic acid / C18-0). Most of the biodiesel products were similar to those of the diesel physical characters. Biodiesel made of waste cooking oil meets the biodiesel quality standard (SNI 7182: 2015) for such parameters of density, viscosity, acid number, saponification value, iodine number and cetane. Esterification and neutralization process are effective in reducing free fatty acids content of waste cooking oil before being used in transesterification with corn cobs ash catalyst.

Authors: Hao Lingfang , Yun Yaofeng , Liang Run , Yuan Gang
Published: December 2020

Purpose: Despite advances in our understanding of the roles of the long noncoding RNA (lncRNA) tumor suppressor candidate 7 (TUSC7) in cancer biology, which has been identified to act as a tumor suppressor by regulating cell proliferation, apoptosis, migration, invasion, cell cycle and tumor growth, its function in colorectal cancer remains unknown.

Methods: The expression levels of TUSC7 in colorectal cancer tissues and cell lines were determined, and the biological functions of TUSC7 to cancer progression in colorectal cancer were investigated via correlation analysis of clinical samples, cell viability assay, transwell assay and apoptosis analysis. Further, the molecular regulatory mechanisms of TUSC7 were demonstrated by luciferase reporter assay and western blotting.

Results: We observed that the expression of TUSC7 was markedly decreased in colorectal cancer cell lines. Moreover, the lower expression of TUSC7 was correlated with advanced clinical grades and poorer survival and may be an independent risk factor for colorectal cancer. Moreover, the expression of TUSC7 inhibited cell proliferation, invasion and epithelial-to-mesenchymal transition (EMT), while it facilitated apoptosis through competitively binding miR-23b. We also found that TUSC7 decreased the expression of phosphodiesterase 7A (PDE7A), a downstream target of miR-23b, through the TUSC7/miR-23b/PDE7A axis.

Conclusion: We demonstrated the expression of TUSC7 suppressed colorectal cancer progression through the TUSC7/miR-23b/PDE7A axis, suggesting that TUSC is a potential target for therapeutic intervention in colorectal cancer.

Authors: Thuy Hoang Dam Luong , Ha Nguyen Thu
Published: December 2020

This study aims to investigate users’ attitude and intention to use of a social media site in the context of the Facebook platform. A questionnaire survey was conducted to collect data from 134 users of Facebook in Vietnam. Collected data were analyzed by using hierarchical regression analysis. This study points out that trustworthiness and perceived usefulness are the direct predictors of intention to use social media sites such as Facebook. Specifically, trustworthiness is found to have the greatest impact on intention to use Facebook, which is followed by perceived usefulness among Vietnamese users. These findings provide evidence about the value of trust and perceived usefulness that can be considered as direct predictors of behavioural intention to use a product or technology. Moreover, remarkable points are recommended for Facebook developers, business managers and the Vietnamese Government in integrating Facebook as well as other online social media platforms and business strategies. As a result, the study can be helpful for future researchers, managers, practitioners and educators in the area of the Vietnamese social media community.

Published: December 2020

En la mosca blanca Trialeurodes vaporariorum, plaga de importancia económica en hortalizas, su manejo con insecticidas sintéticos ha generado resistencia con efectos adversos para el ambiente. En la búsqueda de alternativas de manejo, se planteó esta investigación con el objetivo de cuantificar la repelencia de adultos con extractos crudos (metanol, etanol, diclorometano y hexano), aceites esenciales (AE) y compuestos mayoritarios de clavo y pimienta. En un vaso con 10 mL de agua, se colocó una hoja de tomate tratada a concentraciones de 1,0 a 0,000001 % y se introdujeron 20 adultos de 2 d de edad. Luego, de las 3 a las 72 h, se cuantificaron los adultos posados y por diferencia se determinó la repelencia. Los extractos crudos, AE y compuestos mayoritarios de clavo y pimienta repelieron entre 32,5 y 90,2 % la población de adultos de las 3 a las 72 h. Los AE de clavo y pimienta presentan mejor efecto repelente que los extractos crudos y compuestos secundarios, ya que lograron repeler de 46,2 a 100 %; el AE de clavo a la concentración de 1,0 % logró 100 % de repelencia a las 48 y 72 h y el AE de pimienta alcanza 97,5 % a las 72 h. En la práctica, se debe utilizar extracto crudo etanólico de ambas plantas a la concentración de 0,000001 % ya que logran repeler entre 38,7 y 87,5 % de adultos, de las 3 a las 72 h, y su efecto repelente persiste; además, es más fácil de conseguir, más seguro para el operador, distribuidor y consumidor; y está considerado en las normas de agricultura orgánica como solvente para la extracción de compuestos secundarios.

Different Long Short-Term Memory Approaches to Enhance Prediction-Based Satellite Telemetry Compression
Authors: Mahmoud Tarek A. , Shehab Ahmed F. , Elshafey Mohamed A.
Published: December 2020

Motivated by the success of deep learning in recent years, prediction-based methods are used to compress satellite telemetry data. In this paper, two-stage lossless compression methods for telemetry data are demonstrated. In the first stage, different approaches of long short-term memory (LSTM) based on one-to-one, many-to-one, and many-to-many network architectures are presented. The framework of implementing each approach, as a predictor, is discussed. In the second stage, a set of competing entropy coding methods are tested and evaluated. The presented approaches are capable of exploring correlation dependencies between consecutive samples in the individual and/or successive telemetry frames. The proposed approaches are introduced in two different versions: stacked- and nonstacked-based LSTM architectures trying to achieve higher prediction efficiency. The proposed approaches are tested on real telemetry data, in frames of different data word widths, in distinct FUNcube satellite sessions. The performance of each presented approach, as a predictor, is evaluated based on prediction gain, and reduction in entropy. However, the performance of the whole two-stage lossless compression method is assessed by compression ratio. Comparative analysis is preformed among the proposed approaches, and the improvements are verified against the state-of-the-art prediction-based approaches.

The purpose. In the study we investigated the impact of the partial blood flow shutdown on structural changes in the rabbit vena cava posterior wall after exposure to high-intensity focused ultrasound (HIFU). Methods. Ultrasound Exposure: frequency of 1.65 MHz, the ultrasound intensity in the focus of 13.6 kW/cm, the area of the focal spot 1 mm, continuous ultrasound, exposure for 3 seconds. Results. Immediately after HIFU exposure all layers of the vein wall showed characteristic signs of thermal damage. A week after exposure structural changes in the intima, media and adventitia was minimal in the part of vessel with preserved blood flow, and after 4 weeks the changes were not revealed. A week after HIFU exposure partial endothelium destruction, destruction of myocytes, disorganization and consolidation of collagen fibers of the adventitia were observed in an isolated segment of the vessel, and in 4 weeks endothelium restored and signs of damage in media and adventitia persisted, but were less obvious than in a week after exposure. Conclusion. The shutdown of blood flow after exposure to HIFU promotes persistent changes in the vein wall. Vein compression appears to be necessary for the obliteration of the vessel, when using HIFU-technology.

Цель исследования - изучение структурно-функциональных изменений нейронов сенсомоторной коры головного мозга белых крыс в норме и после 20-минутной окклюзии общих сонных артерий. Методика. С помощью световой (окраска гематоксилином и эозином, по Нисслю), флуоресцентной (окраска DAPI), иммунофлуоресцентной (нейронспецифическая енолаза - NSE) и электронной микроскопии была изучена нейроцитоархитектоника сенсомоторной коры (СМК) головного мозга белых крыс в норме (n =5) и в динамике - 1, 3, 7, 14, 21 и 30 сут.; после 20-минутной окклюзии общих сонных артерий (n =30). Согласно рекомендациям Nomenclature Committee on Cell Death (2009), проведено детальное описание и сравнение всех морфотипов измененных пирамидных нейронов СМК мозга белых крыс после острой ишемии. Морфометрический анализ проведен с помощью программы ImageJ 1.46. Результаты . Использование комплекса морфологических методов позволило классифицировать нейроны на основании четких структурных маркеров и доказать возможность апоптоза гиперхромных нейронов СМК после воспроизведения ишемии. Показано, что через 3 сут. в слое III 6-12% гиперхромных нейронов подвергалось апоптозу, 13,4-24,6% - коагуляционному некрозу, а остальные выходили из патологического состояния в отдаленном восстановительном периоде. Необратимо измененные клетки-тени составляли 11,5% (95% ДИ: 7,4-16,8%). Общая численная плотность пирамидных нейронов в течение 30 сут. постишемического периода в слое III СМК снижалась на 30,5% (95% ДИ: 24,2-38,7%), а в слое V - на 14,4% (95% ДИ: 9,9-20,0%). Заключение. Показана смешанная природа гибели нейронов - одновременное сочетание процессов некроза и апоптоза (парапоптоз). Однако основную роль в гибели нейронов играли процессы быстрого и отдаленного ишемического некроза.
