Authors: Benito José Alexander
Published: August 2021

Hacer énfasis en la práctica pedagógica partiendo de algunas consideraciones teóricas con las cuales se intenta definir su sentido desde la mirada del maestro y su acción pedagógica permeando los diversos sentidos y dominios que trae consigo el oficio docente, y necesariamente al profesor de lenguas extranjeras desde su formación inicial hasta su formación formal en la docencia. Es necesario seguir trabajando en ello debido a que los contextos y los lugares que ocupa la escuela son diversos y únicos y a su vez cambiantes en el tiempo, esta idea se resume en que los profesores deben estar en constante aprendizaje activo mientras enseñan.
Impact on the Individual Consciousness of in the Context of Ethnocultural Identity
Authors: Bochkaev A. R.
Published: August 2021

The consciousness of individuals and the masses becomes the object of inﬂuence on the part of both political elites and political technologists In this context, the topic of the group, including ethnocultural, self-identifcation of the individual, becomes relevant This question was considered in the works “Psychology of Peoples and Masses” by Gustave Lebon and “Escape from Freedom” by Erich Fromm One of the latest trends in the impact on the consciousness of individuals and the masses is the “consentient war”, that is, the war for consciousness Group consciousness leads to the deindividualisation of individuals However, its value can be ambiguous On the one hand, the individual feels the integrity of his personality On the other hand, as he is in a cultural society, however, he often has to be guided by ethnic values even if they do not correspond to his semantic attitudes This issue was considered in the works “The Psychology of Nations and Masses” by Gustav Le Bon and “Escape from Freedom” by Erich Fromm The United States today seeks to merge cultural patterns through globalisation The fnal step towards achieving this goal is control over the Heartland, the Russian Federation’s centre One of the newest trends in the impact on the consciousness of individuals and the masses is becoming “consciential war”, that is, a war for consciousness Group consciousness leads to the deindividualisation of individuals.
Positioning the Events of the Great Patriotic War in the Framework of the state Policy of Memory: Problems and Prospects
Authors: Seleznev P. S. , Alexandrov D. V.
Published: August 2021

Within the framework of this study, the problem of identifying shortcomings in the current model of positioning the events of the Great Patriotic War at the state level is being solved in terms of assessing the prospects for its development The methodology of this work is formed through a combination of descriptive analysis and secondary processing of data from mass surveys of leading sociological agencies in Russia The theoretical foundation of the research is built by integrating the concepts of social memory by Durkheim, M Halbwachs, P Riker and J Assmann The authors concluded that the current model of the memorial positioning of the events of the Great Patriotic War by the state is built without considering some fundamental laws of the formation of social memory in the context of reproduction and preservation of national-state identity The basic symbols that determine the space of the memorial narrative can be positioned fundamentally, depending on the context of the narrative and the specifcs of the political situation The most important contradiction is manifested in the declaration of mass heroism, and outstanding achievements against the background of the negative positioning of the socio-political are levelled through the negative context within which the previous and subsequent events are described There is a lack of reﬂection on the expected change in the broadcast formats of the memorial narrative in the medium term at the strategic level.

Authors:   1Universidade Católica de Pelotas
Published: August 2021

Objective: Analyze mortality rates of the HIV disease in Brazil in a period of 20 years to determinate the behavior of the rates and the pattern of the victims. Methods: Data were collected from the Mortality Information System (SIM) by the Informatics Department of the Unified Health System (DATASUS) regarding deaths from HIV disease. All records and year of death, race, sex, age group, marital status and educational level of the person were considered. Results: In the 20 years studied, 232,274 deaths caused by the disease were recorded, an average of 11,613.7 (±1092.7) per year. White people represent 46.4%, followed by brown, 32.8%. Men are majority throughout the period, with 67.1% of records. People between 30 and 49 years old have the highest rates, 62.1% of deaths. Single people were majority, 61.1% of the total. As for education, people with up to 7 years of education correspond to 44% of deaths, while people with 12 years and more of education account for only 5.6%. Conclusions: White men, between 30 and 49 years old, single and with up to 7 years of schooling are, according to statistics, the most predisposed to die from the HIV disease. Especially from the data on education, it can be inferred that a higher level of education reduces the risks of death from the disease. Knowing this and the information about single people being more affected, the importance of sex education to early school years is recommended, as well as guidance in primary care.

Objetive: This review aims to approach the impact that airborne fungi have in collections, mainly in libraries, and also their impact in the health of the people who works and visiting there. Methodology: The search was made with the most recent papers, with free access in online databases: Pubmed (National Library of Medicine and the National Institutes), Lilacs (Latin-American and Caribbean Literature in Health Science, acronym in Spanish) and Scielo (Scientific Electronic Library Online), by using key words related with the proposed theme. Results: Libraries have substrates and residuals that allow the presence and proliferation of airborne fungi. These fungi are biodeteriorators that attack the collections but also can cause respiratory diseases, mycoses, or even systemic diseases. The most common genera are Aspergillus, Penicillium, Cladosporium, Alternaria, Acremonium and Fusarium. These fungi have asexual reproduction by producing tiny dry spores that can remain viable by long periods on the air and can also be transported on it. Preserve collections demands control of air temperature and humidity, to inhibit the airborne fungi proliferation and thus, decreasing the risks to human health. Conclusion: The knowledge about airborne fungi as contaminants in libraries environment it is of utmost importance for the development of preventive actions for preservation of the collections and also for the health of people who works in or visit them.

Published: August 2021

El objetivo fue analizar el agroecosistema de calabaza pipián para identificar problemas, eficiencia energética y financiera comparando producción de semilla seca a cuando se le da valor agregado (jamoncillo) en la comunidad de Cantarranas Municipio de Paso de Ovejas, Veracruz, México. Esta investigación se realizó en 2018, usando técnicas participativas y entrevistas semiestructuradas, análisis financiero y de productividad energética. El grado de interacción y comunicación entre agricultores fue analizado con el programa UCINET. Se encontró que el estado de Veracruz se ubica en séptimo lugar en la producción de semilla de pipián a nivel nacional, el municipio de Paso de Ovejas ocupa el decimoquinto lugar en el estado. El análisis de energía mostró una mayor productividad energética para el producto de valor agregado de pipián (jamoncillo) en contraste con la producción de producción de semilla. El análisis financiero mostró una baja rentabilidad para la producción de semilla (precio de 2017: Mex $20.00 kg-1). Se encontró una baja conectividad en la red de agricultores, lo que resulta en una comercialización individual generando bajos ingresos al productor. Es necesario adoptar formas más sostenibles de producción de calabaza pipián y promover una pequeña industria en la región.

Authors: Macías-Carranza Víctor , Cabello Pasini Alejandro
Published: August 2021

Los índices bioclimáticos, incluyendo la evapotranspiración, se han utilizado de manera conjunta para caracterizar el clima en una región y correlacionar su influencia en los procesos fisiológicos de la vid y en la calidad del fruto y del vino, así como caracterizar y definir zonas de cultivo. Sin embargo, se han realizado pocos estudios para caracterizar las regiones vitivinícolas en México. Por lo anterior, el objetivo de este trabajo fue el de caracterizar las regiones vinícolas de Baja California de acuerdo con las variables climáticas. Se evaluó la temperatura ambiental, irradiancia, humedad relativa, velocidad y dirección del viento en el Valle de Guadalupe (VG), San Antonio de las Minas (SAM), San Vicente (SV) y Santo Tomás (ST) en Baja California de 2013 a 2018. La relación que existe entre los índices bioclimáticos de GDD y HI fue significativamente alta, indicando que estos dos índices capturan la misma información climática. Usando los GDD se clasificaron los valles de SAM y SV como región IV (templado-cálido) mientras que VG y ST se catalogaron como región V (zonas cálidas y muy cálidas). De una manera similar, la evapotranspiración en SAM y SV fue 15% menor a la observada en VG y ST. Estos resultados ayudan a establecer las zonas más adecuadas para la viticultura, así como para el manejo del agua en Baja California.

Published: August 2021

El objetivo de la presente investigación fue actualizar el mapa de climas del estado de Jalisco de acuerdo con la clasificación climática Köppen-García, con base en imágenes raster climáticas de alta resolución (90 m) y un ajuste por correspondencia climas-vegetación potencial. Se trabajó con datos climáticos diarios, mensuales y anuales de 154 estaciones meteorológicas del estado de Jalisco y 151 estaciones de estados vecinos. Los datos corresponden a la serie 1961-2014 en el caso de las estaciones de Jalisco y la serie 1961-2010 para estados vecinos. Con esta información se obtuvieron imágenes raster para la clasificación del clima con el método Köppen-García, mediante procesos de interpolación implementados con el método Anusplin. En el sistema Idrisi y utilizando rutinas de álgebra de mapas, se obtuvo el mapa de climas de Jalisco a nivel de tipo y subtipo climático. Dicho mapa se corrigió atendiendo a la correspondencia de los climas obtenidos con la vegetación potencial según COTECOCA. Los resultados mostraron correspondencia de 84% entre climas y tipos de vegetación y sólo 16% de los polígonos climáticos fueron corregidos. Se obtuvieron 29 variantes climáticas, de las cuales, los climas secos o semiáridos representan 13.78% del territorio estatal, cálido húmedos Aw el 21.77%, semicálidos húmedos A(C)w el 4.45%, semicálidos húmedos (A)C(w) el 41.67%, templados húmedos Cw el 18.33% y fríos E, el 0.001%. En orden descendente, el número de climas por región fue: Región Sur 21, Costa Sierra Occidental 19, Sierra de Amula 18, Norte 14, Sureste 13, Costa Sur 12, Altos Sur 11, Valles 10, Lagunas 9, Centro 8, Altos Norte 7 y Ciénega 7. Se concluye que el estado de Jalisco posee un gradiente térmico de cálido a frío, incluyendo la semicálida y templada y por un gradiente de humedad la semiárida hasta la subhúmeda monzónica. Los autores consideran que los mapas climáticos obtenidos, pueden ser útiles en aplicaciones para diversas áreas, como la agricultura, edafología, ecología y ciencias ambientales.
Las escuelas normales en Chile y Argentina (1821-1974). Un estudio comparado
Authors: Pérez-Navarro Camila , Rodríguez Laura Graciela
Published: August 2021

El presente artículo analiza, desde una perspectiva comparada, el proceso de creación y expansión de las escuelas normales en Chile y Argentina, desde principios del siglo XIX hasta la década de 1970. Con base en la revisión y análisis del contenido de diversas fuentes primarias documentales, dicho proceso se analiza a partir de tres ejes: las influencias extranjeras que recibió el normalismo en distintas épocas, el proceso de feminización del magisterio y las reformas más importantes que se implementaron. Pretendemos mostrar, que, en diferentes momentos, se recibieron aportes del sistema lancasteriano inglés, y de los modelos francés, norteamericano y alemán. En segundo término, señalaremos cómo, en ambos países, las autoridades pensaron en los inicios formar un magisterio masculino, pero al poco tiempo debieron cambiar la estrategia y abrir más normales para mujeres. Por último, señalaremos en qué sentido, las reformas de los años de 1940 en Argentina, y luego las de 1960 en las dos naciones, resultaron profundas y cambiaron la estructura del normalismo.
Ciencias naturales en primaria en los años setenta en México: ¿Una reforma entre revoluciones?
Authors: Estrada Rebull María del Mar
Published: August 2021

En la década de 1970, en el marco de la reforma educativa de Luis Echeverría, un grupo liderado por científicas y científicos mexicanos diseñó una gran reforma curricular de ciencias naturales en primaria. Se ha explicado que esta reforma fue una réplica con retraso de la llamada “primera revolución” en educación en ciencia, originada en Estados Unidos, que buscaba una enseñanza de las disciplinas científicas “tal cual eran” mediante el método científico y la experimentación. Este artículo va más allá de esa explicación: analiza el contexto de la reforma, su proceso de diseño y sus libros de texto bajo una mirada histórica, filosófica y social sobre la ciencia y la tecnología. Muestra cómo la reforma abrevó de largas tradiciones del mundo occidental, y a la vez reflejó significados locales de la naturaleza, el campo, la ciencia, la tecnología y su papel para la niñez y el México de entonces.
Study of Bio-fertilizer Produced from Agro-waste (Sesame Straw) and Cow Dung Using Eisenia fetida and Perionyx sansibaricus in Arid Environment
Authors: Panwar K. R. , Tripathi G.
Published: August 2021

In this study, an analysis of organic fertilizer of an agro-waste (Sesame straw) plus cow dung was carried out using an epigeic earthworm species Eisenia fetida and Perionyx sansibaricus. Sesame straw is abundantly produced after each harvesting of the crop in Kharif season in arid region of tropical India. The compost produced in presence and absence of earthworm exhibit significant (P<0.001) and non-significant (P>0.05) changes in physicochemical properties respectively. In control bedding, the values of water holding capacity enhanced significantly (P<0.05) by 1.28 fold, while organic carbon and C/N ratio decreased significantly (P<0.05) by 19.93% and 31.25% respectively after 60 days of composting.Working of E. fetida in the bedding material showed significant (P<0.001) difference in the level of pH, electrical conductivity, water holding capacity, organic carbon, total nitrogen, C/N ratio, available phosphorous and available potassium. After 60 days of working of P. sansibaricus, these physicochemical properties of the bedding substrate also changed significantly (P<0.001). Analysis of vermibed showed a gradual increase in electrical conductivity, water holding capacity, total nitrogen, available phosphorus and available potassium by 1.51, 1.86, 1.95, 1.78 and 1.75 fold respectively. While the values of pH, organic carbon and C/N ratio declined by 9.30%, 41.80% and 71.48% respectively within 60 days of decomposition. Thus, E. fetida and P. sansibaricus can be applied for production of organic fertilizer of sesame chaff plus cow dung to fulfill the requirement of bio-fertilizers for organic farming and agro-waste management in arid environment.

Published: August 2021

Одним из этапов технологического процесса производства оригинального семенного картофеля является выращивание оздоровленных пробирочных микрорастений в весенне-летней теплице для получения мини-клубней. Исследования проводили в Приморском крае на оздоровленных безвирусных пробирочных растениях картофеля (Solanum tuberosum L.) сорта Метеор, размноженных методом микрочеренкования в культуре in vitro. Данный сорт был выбран вследствие его скороспелости. В ходе эксперимента при выращивании микрорастений изучено влияние сочетания факторов — объем пробирок, состав почвенного грунта и площадь питания растения на производство мини-клубней картофеля в условиях искусственного освещения. Дана оценка продуктивности пробирочных растений и определена роль основного фактора, влияющего на выход мини-клубней картофеля сорта Метеор, в лабораторных условиях. Установлено, что основное влияние на производство стандартных мини-клубней картофеля оказал состав почвенного грунта. Максимальное количество стандартных мини-клубней картофеля сорта Метеор (209,3 и 156,1 шт./м2) получено в вариантах опыта при использовании грунта с содержанием элементов питания: фосфора — 1380 мг/кг, калия — 1425 мг/кг, азота — 1394 мг/кг, органического вещества — 66,7 %.

Published: August 2021

Гены высоких значений удельной поверхностной плотности листа (УППЛ) и каротиноидов (Rm347 и Rm154) связаны с эффективностью фотосинтеза российских сортов риса. В целях маркер-ориентированной селекции риса Oryza sativa L. определяли их в дальневосточных сортах и гибридах риса. Наличие аллелей, контролирующих высокое содержание каротиноидов, выявлено у сортов Алмаз, Садко и Дубрава, коллекционном образце Oxy 2x и в 15 гибридах 4 гибридных комбинаций. Аллели высоких значений УППЛ, не обнаруженных в сортах, выявлены в коллекционном образце Oxy 2x и 5 гибридах, полученных с участием этого образца. Для маркер-ориентированной селекции в дальневосточном регионе наиболее ценным является сорт риса Садко, обладающий аллелями устойчивости к пирикуляриозу 2 генов [Pi-z(t) и Pi-ta2] и аллелем высоких значений каротиноидов, а также коллекционный образец Oxy 2x, в котором идентифицирован аллель устойчивости к пирикуляриозу гена Pi-b и аллели высоких значений УППЛ и каротиноидов. В качестве перспективных образцов для селекции на повышение эффективности фотосинтеза выступают гибриды, полученные с участием коллекционного образца Oxy 2x. Rm154 и Rm347 являются маркерами доминантного типа, что позволяет использовать их для идентификации истинных гибридов риса.

Published: August 2021

Виноград в период роста и развития на плантации, в школке или в микротеплице после прививки поражается большим количеством болезней. Основными наиболее вредоносными инфекционными заболеваниями винограда являются: серая и белая гнили, милдью, оидиум, антракноз. При производстве саженцев винограда инфекционные болезни в основном контролируют применением фунгицидов различной природы происхождения. Использование биологических препаратов именно в этот период обеспечивает оздоровление черенков от болезней и насыщает их необходимыми элементами питания. Установлено влияние температурных режимов и насыщения паром с препаратом Альбит, ТПС привитых саженцев сорта Кристалл на классическом подвое Кобер 5 ББ на процессы каллусообразования, содержание микроэлементов и влаги в прививках, выход саженцев, морфологические показатели и приживаемость на плантации. Опыты проведены с использованием экспериментальной установки в Ростовской области в 2016 – 2018 гг. Повторность опытов 3-кратная, в каждом варианте изучали 90 растений винограда. Наиболее оптимальным для обеззараживания и насыщения прививок винограда макро- и микроэлементами является насыщение прививок препаратом Альбит, ТПС при 45 – 50 °C длительностью 10 мин. Такой способ позволяет значительно увеличить выход саженцев, а также повысить качественные показатели саженцев, приживаемость и хорошее развитие на плантации.

Vinte Anos de Diálogos: Os esportes na antropologia brasileira
Authors:   Luiz Fernando Rojo,   Wagner Xavier de Camargo,   Mariane da Silva Pisani
Published: August 2021

This book rescues twenty years of activities in the Sports Anthropology Working Group at the Brazilian Association of Anthropology. Its chapters present a panorama of research presented in this period as well as the several dialogues with other areas, which identify an interdisciplinary existence. A team of male and female researchers, from different backgrounds and areas of studies, decided to play together and produce scientific knowledge over the body and sports practices under the spectrum of anthropology, but also at the interface with other Human Sciences. It is in this context that this collection simultaneously proposes to celebrate such twenty years of participation in sports studies at the Brazilian Conferences of Anthropology, as well as pointing out paths for the next stages of building the Anthropology of Sports in Brazil and worldwide. Taking stock of the dialogues established between this field of investigation and the multiple disciplinary areas with which it has been built, this team of specialists turns a kaleidoscope of analytical possibilities on the object in question. If such studies systematize so far a consolidated trajectory, they also open up potentials for theoretical and ethnographic unfolding to future investigations.

An Investigation into Factors Affecting Speaking Performance of HUFI English-majored Students
Authors: Ngoc Vo Thi Bich
Published: August 2021

Spoken language outcomes are considered an extremely difficult aspect of language learning ( Brown & Yule, 1983). Speaking English is of utmost importance to English language qualification students. Students have different problems and different difficulties with speaking English. Many students receive it difficult to express themselves in spoken language. He stops talking when hindered by the psychological fear of not finding the right words and expressions. The present research aims to describe the difficulties that may be encountered and to investigate factors affecting the speaking performances of students at the HCMC Food Industry University. Students have attempted to deal with their problems in speaking, but their efforts have yet to be successful and effective. The research paper aims to establish the necessary focus on the important factors affecting the speaking performance of students studying a second language. The research demonstrates the importance of speech characteristics in speaking performance problems and the factors that influence speaking outcomes. The research is performed using both quantitative methods and corrected from previously relevant information. The study was carried on recovering their speaking performances of HUFI English-majored students.

Background: Psychosocial stress during the COVID-19 pandemic is increasing particularly in parents. Although being specifically vulnerable to negative environmental exposures, research on psychosocial stress factors in infants’ and toddlers’ families during the pandemic is so far sparse. The CoronabaBY study investigates the perceived pandemic burden, parenting stress and parent and child mental health problems in families with children aged 0-3 years in Bavaria, Southern Germany. Further, the relationships between these psychosocial stressors are examined and sociodemographic characteristics that may be predictive of these factors will be explored.Methods: Participants were cross-sectionally surveyed via smartphone app. Standardized questionnaires on perceived pandemic burden, parenting stress, parental symptoms of depression and anxiety, infants’ crying, sleeping and feeding problems or toddlers’ emotional and behavioral problems were applied.Results: N = 991 parents (Mage = 33.7 years, SD = 4.5; 93.7% mothers, 91.5% born in Germany) with infants (n = 554; Mage = 5.9 months, SD = 3.0) or toddlers (n = 435; Mage = 25.9 months, SD = 6.5) participated in the first half-year of 2021. Sixty-five percent of the parents perceived a high pandemic burden, 37.7% experienced parenting stress and 24.1% showed affective symptoms (anxiety: 30.1%, depression: 18.5%). Feeding problems, crying/ sleeping problems and multiple regulatory problems were found in 34.8%, 26.2% and 13.5% of the infants, respectively. Amongst toddlers, 8.5% showed noticeable behavior and emotional problems. Children`s mental health problems correlated moderately with parenting stress and parental affective symptoms and weakly with perceived pandemic burden. A lower financial status, higher parental education and increasing child age were significant but weak predictors for higher parenting stress, affective symptoms and higher psychological problems in children. Conclusions: A majority of the surveyed families with infants and toddlers experience the pandemic as stressful. The main challenges are parental affective symptoms and limited resources for childcare due to parenting stress. Overall, infants and toddlers show similar levels of mental health problems when being compared to pre-pandemic studies, but staggered detrimental effects on children`s mental health might occur if the stressful conditions persist. This is already indicated by correlations between parental and child psychosocial stress factors.
Integrating and Distinguishing Personality and Psychopathology
Authors: Wright Aidan G.C. , Hopwood Christopher James
Published: August 2021

We asked authors of this Special Issue to answer four questions: 1) Is there evidence thatpersonality and psychopathology can be integrated?, 2) Is integration important?, 3) Can they be distinguished?, and 4) How can the difference be measured?. Authors uniformly agreed that personality and psychopathology can be integrated within a common structure and that this is important. The third and fourth questions were more challenging. While authors generally agreed that there is a distinction between the person and the person’s mental health problems, articulations of that distinction were fuzzy and it is clear that current methods are not sufficiently capable of delineating these domains. We summarize the issue by offering four directions for future research: 1) develop measurement tools that distinguish between the person, the context, and their transaction, 2) measure behavior and context at multiple timescales, 3) use multimethod data to tap different levels of behavior, and 4) examine person-specific processes. Each of these directions comes with considerable challenges, but the payoff of solving them will be a more principled, evidence-based, and clinically-useful model for the distinction between personality and psychopathology.
‘Can I trust you?’ A study of the psychological factors influencing school children’s decision to trust and peer’s perception of their trustworthiness
Authors: Wong Keri Ka-Yee
Published: August 2021

**Author NotesThis manuscript has been submitted for publication and is likely to be edited as part of the peer-review process. Correspondence regarding this paper should be addressed to Keri Ka-Yee Wong, keri.wong@ucl.ac.uk.**How children’s trust beliefs in others and how peers determine children’s levels of trustworthiness is the bedrock of all relationships. Yet very little prior research exists on understanding the nature of this relationship and even fewer studies compare across cultures to understand the specificity of potential interventions. This study addressed these gaps by conducting a set of serial mediation models to test the hypothesized causal flow from social mistrust and its subscales (home, school, general mistrust) to anxiety to aggression and to peer-rated untrustworthiness in 2,464 school children aged 8-14 years from the UK (N = 994; M = 11.38 years, female = 45.6%) and Hong Kong (N = 1,470, M = 11.46 years, female = 47.1%). Increased levels of self-reported social mistrust (and its associated subscales) were found to be independently associated with increased untrustworthiness in both countries. Children with high levels of social mistrust, particularly school mistrust, were more likely to have high levels of anxiety and aggressive behaviors concurrently, which in turn was associated with higher levels of peer-rated untrustworthiness. This explanatory model suggests that future longitudinal intervention studies that aim to reduce aggressive responses from suspicious children may improve peer’s perception of untrustworthiness and childhood relationships with others.

The first few months of postnatal life are critical for establishing key neural connections that support the development of subsequent social, cognitive, and linguistic skills. Yet, the United States lacks a national policy of paid family leave during this important period of early brain development, despite previous research demonstrating links between paid leave and improved maternal mental health, lower rates of infant mortality, and increases in cognitive skills during toddlerhood. The current study examined associations between paid maternal leave and infant brain function at 3-months of age using electroencephalography (EEG). Even after controlling for influential infant and family characteristics, results indicate that compared to unpaid leave, experiences of paid leave were related to distinct EEG profiles, possibly reflecting more mature patterns of brain activity. Findings from this study support past work demonstrating the benefits of paid leave on infant cognitive development and extend this work into early neural functioning. Together with past research, this work suggests that policy interventions mandating paid family leave may lead to reductions in sociodemographic health disparities and set the stage for healthy neurocognitive development.
A Survey on Difficulties in Giving English Presentations Experienced by Students at Ho Chi Minh City University of Food Industry (HUFI)
Authors: Le Cuong
Published: August 2021

Nowadays, oral presentation plays an important role in the university environment. Nevertheless, most students still do not have enough experiences and skills in presenting, which leads them to deal with various problems. In an effort to investigate their presenting difficulties, this research aimed to point out: (1) the students’ attitudes towards the importance of oral presenting skills, (2) the difficulties when presenting they would encounter, and (3) the factors causing the challenges and some suggested solutions. Specifically, the investigation has been carried out in the form of survey research, with a hundred and forty students at Ho Chi Minh City University of Food Industry participating as informants. The main data collection instrument was the online survey questionnaire done by those students. The research has indicated that the students’ poor linguistic proficiency, including their pronunciation, nonverbal communication, lack of interaction, all found it hard for them to be comprehended. Furthermore, the data collection has confirmed that the assessments and comments from the institution’s lack of high-quality equipment and facilities also related to these students' poor presenting performances. For those reasons, the investigation recommends that teachers and institutions should make greater efforts in educating oral presenting skills to better their students’ presentation skills. On the students’ part, it is essential to be more aware of the preparations and to have suitable strategies for enhancing presentation abilities to meet the expectations of future work.

The sudden shift of English language teaching from face-to-face classroom interaction to online learning has resulted in many challenges for EFL students in Ukraine. The aim of the study is to analyze the challenges EFL students at Ukrainian higher educational institutions face under the Covid-19 pandemic and quarantine measures. Mastering a foreign language requires the development of foreign language skills, motivation, self-esteem, emotional stability, and psychological involvement of students in the learning process. There was the survey for English language learners at Ukrainian Universities: Kyiv National University of Trade and Economics Borys Grinchenko Kyiv University, Kyiv National Linguistic University, Taras Shevchenko Chernihiv National University “Chernihiv Collegium.” The study analyzes the responses of 357 students. The researchers surveyed in 2020. The results of the study show that students have psychological challenges in the process of learning foreign languages. They are caused by low self-esteem, demotivation, frustration, fear of failure, the impact of quarantine measures and conditions: lack of face-to-face interaction, pandemic-related stress, anxiety, depression, etc. The author uses the methods of theoretical analysis, synthesis, comparison, classification, and systematization of theoretical and experimental data. The results of this study provide recommendations for EFL teachers to enhance the efficiency of online teaching and learning activities. The study presents some recommendations for EFL teachers to guide their students through online learning.
