Diseño de un ambiente de aprendizaje blended learning como propuesta de innovación educativa en la Universidad de la Sierra Juárez
Authors: Mendez Gijon Florentino , Morales Barrera Magda Concepción
Published: September 2020

Evaluada como pedagógicamente exitosa donde ha sido implementada, la modalidad blended learning combina la enseñanza presencial con la virtual. En este trabajo se presenta una propuesta de diseño de un ambiente de aprendizaje para esta modalidad para el contexto educativo de la Universidad de la Sierra Juárez (Unsij). El desarrollo del ambiente se realizó con la metodología de investigación basada en el diseño (IBD), que permitió generar un prototipo de enfoque socioconstructivista adecuado al contexto universitario de la Unsij. En un primer momento, se realizó el diagnóstico del contexto para, entre otras cosas, analizar el mapa curricular de los programas educativos, valorar la infraestructura tecnológica con la que cuenta la universidad e identificar las actitudes y competencias digitales docentes. Como parte de los resultados, la universidad cuenta con recursos digitales/tecnológicos que sirven de apoyo a la docencia, pero no con una plataforma digital de gestión del aprendizaje (LMS). Asimismo, existe una actitud favorable de los profesores para usar las tecnologías de la información y la comunicación (TIC) en su práctica docente y un nivel de competencia intermedio en el conocimiento y uso en diversas actividades, pero un nivel bajo en el uso de estas herramientas para el diseño de actividades didácticas. Por último, el modelo educativo de la institución es de tipo presencial a tiempo completo, con planes de estudio que se agrupan en dos periodos semestrales y uno de verano; en los periodos semestrales se cursan cinco materias a las que los estudiantes deben dedicar horas de estudio con docente (presencial en aula) y otras independientes. La información obtenida ayudó al diseño de un ambiente de aprendizaje para la modalidad blended learning, que si bien continúa a prueba y se mantiene en proceso de evaluación y seguimiento, hasta este momento ha ayudado a mejorar la práctica docente en un ambiente mediado con TIC.
Determinantes de la inserción laboral en egresados universitarios en México
Authors: Pérez Cruz Omar Alejandro , Pinto Pérez Rogelio
Published: September 2020

La diversidad de cambios económicos, tecnológicos y sociales que se han experimentado en la última década ha influido en el mercado laboral, en las formas de entender la configuración y la dinámica del empleo, en los procesos de transición entre educación y trabajo, en las estrategias de formación, así como en los progresivos ajustes entre los planes curriculares de las instituciones de educación superior y la iniciación e inserción de los egresados al mercado laboral. Este artículo expone una revisión de algunos de los factores centrales en torno a la relación entre la educación superior y el mundo laboral, con la finalidad de contextualizar la empleabilidad como concepto, práctica e instrumento de la política económica y educativa en México. El objetivo fue estimar la significatividad estadística que un conjunto de variables predictivas (titulación, elementos académicos, elementos curriculares y habilidades personales) ejerce sobre la dependiente (inserción laboral). Para tal fin, se ha implementado un estudio de encuesta mediante una estrategia mixta (online y telefónica), al igual que un análisis econométrico, con datos panel y regresión de mínimos cuadrados ordinarios (MCO) con errores estándar corregidos. Los resultados muestran que los titulados, y más los titulados por el Examen General para el Egreso de Licenciatura (EGEL), se asocian significativamente con la inserción laboral. Asimismo, las variables de emprendimiento, trabajo en equipo, ambiente de trabajo, prácticas de talleres y laboratorios y manejo de las tecnologías de la información y comunicación (TIC) se asocian significativamente con la inserción laboral. Al gestionar estas variables, es posible incrementar la probabilidad de los egresados de insertarse en el mercado laboral.
The relationship between China-South Pacific island countries tourism and trade in the context of the Belt and Road Initiative
Authors: Ye Fang , Park Jaepil , Li ChunLin , He Yixiong
Published: September 2020

In the context of the Belt & Road Initiative (BRI), China attaches great importance to tourism diplomacy with the South Pacific Island Countries (SPIC). The study of the relationship between tourism and trade is therefore of great significance for the further development of bilateral political and economic cooperation. This paper selected data on the inbound and outbound tourism, as well as import and export trade, between China and SPIC in the period 1998-2017, and used econometric methods to demonstrate the interconnections. The results show that there is a positive long-term equilibrium relationship between passenger flow and import and export trade of China and SPIC. Under the influence of policies, the interaction between inbound and outbound tourism and import and export trade is characterized by periodic fluctuations. China’s outbound tourism to SPIC plays a stronger role to import trade than to export trade. From the analysis of two sections, major events have a moderating effect on the proportion of SPIC tourists and trade dependence on SPIC, while both of the proportion of Chinese tourists and their trade dependence on China are on the rise, and these two have a pulling effect for each other.
Différences entre les sexes quant à l’association longitudinale entre classes latentes multiniveaux de comportements à risque associés aux maladies chroniques et indice de masse corporelle chez les adolescents
Authors: Hammami Nour , Chaurasia Ashok , Bigelow Philip , Leatherdale Scott T.
Published: September 2020

Introduction

Peu d’études ont évalué la relation entre des comportements à risque associés aux maladies chroniques et l’indice de masse corporelle (IMC) dans un contexte longitudinal sexospécifique. Cette étude s’appuie sur des analyses sexospécifiques pour évaluer dans quelle mesure des classes latentes de comportements à risque associés aux maladies chroniques fixées au départ sont liées à l’IMC et au statut pondéral lors du suivi.

Méthodologie

Des données longitudinales provenant de 4 510 élèves de la 9e à la 12e année, suivis de 2013 à 2015 dans le cadre de l’étude COMPASS, ont servi à évaluer les différences entre les sexes dans l’association décalée entre des classes latentes déterminées au départ (d’activité physique et de consommation de substances) et l’IMC lors des phases ultérieures au moyen de modèles multiniveaux à effets mixtes. Nos modèles de régression multiniveaux ont permis d’évaluer l’association entre deux classes latentes, les jeunes expérimentateurs actifs et les jeunes inactifs qui ne consomment pas, et l’IMC, lorsque les données sont stratifiées selon le sexe.

Résultats

Les garçons inactifs qui ne consomment pas ont été associés à un IMC continu plus élevé de 0,29 (IC à 95 % : 0,057 à 0,53) ainsi qu’à une probabilité d’embonpoint ou d’obésité supérieure de 72 % (RC = 1,72; IC à 95 % : 1,2 à 2,4) pour l’IMC binaire lors du suivi par rapport aux garçons actifs qui expérimentent la consommation de substances. Aucune association significative n’a été décelée chez les filles.

Conclusion

Au fil du temps, l’activité physique joue un rôle protecteur relativement à l’IMC chez les garçons. La consommation de substances et l’inactivité physique devraient toutes deux être ciblées par les efforts de prévention de l’obésité. La stratification selon le sexe dans les analyses est également importante, car l’augmentation de l’IMC dépend de facteurs différents chez les garçons et chez les filles.
Validation de Canproj pour les projections de données sur l’incidence du cancer au Canada
Authors: Demers Alain , Qiu Zhenguo , Dewar Ron , Shaw Amanda
Published: September 2020

Introduction

Les projections relatives au cancer fournissent une information essentielle pouvant aider à établir l’ordre de priorité des stratégies de lutte contre le cancer, à répartir les ressources et à évaluer les interventions et les traitements actuels. Canproj est un outil de projection pour le cancer utilisant le progiciel R qui est inspiré de Nordpred et qui ajoute une sélection de modèles de projection. L’objectif de ce projet consistait à valider Canproj, programmé avec R, pour les projections à court terme relatives aux taux de cancer.

Méthodologie

Nous avons utilisé les données nationales sur l’incidence du cancer tirées du Système national de déclaration des cas de cancer et du Registre canadien du cancer pour 1986 à 2014. Nous avons utilisé la validation croisée pour estimer l’exactitude des projections générées par Canproj, avec le biais relatif (BR) comme mesure de validation. Nous avons également évalué l’arbre décisionnel de Canproj pour la sélection automatique du modèle.

Résultats

Cinq des six modèles ont présenté un BR moyen se situant entre 5% et 10 % et un BR médian d’environ 5 %. Dans le cas de certains sièges de cancer pour lesquels il était plus difficile d’établir des projections, l’utilisation d’une période plus courte a permis d’améliorer la fiabilité. Le modèle Nordpred a été sélectionné dans 79 % des cas par la fonction de sélection automatique de modèle de Canproj, même s’il offrait le BR le plus faible seulement 24 % du temps.

Conclusion

Le progiciel Canproj a été en mesure de fournir des projections très semblables aux données réelles pour la plupart des sièges de cancer.
Natural language processing for analysis of student online sentiment in a postgraduate program
Authors: Pham Truc D , Vo Darcy , Li Frank , Baker Karen , Han Binglan , Lindsay Lucie , Pashna Mohsen , Rowley Rich
Published: September 2020

Higher education institutes are continually looking for new and better ways to support and understand the learning experience of their students. One possible option is to use sentiment analysis tools to investigate the attitudes and emotions of students when they are interacting on social media about their course experience. In this study, we analysed the social media posts, from a closed programme-based community, of more than 300 students in a single programme cohort by processing the dataset with the Google cloud-based Natural Language Processing API for sentiment analysis. The sentiment scores and magnitudes were then visualised to help explore the research question ‘How does a natural language processing tool help analyse student online sentiment in a postgraduate program?’ The results have provided a better understanding of students’ online sentiment relating to the activities and assessments of the programme as well as the variation of that sentiment over the timeline of the programme.
The Power of Testimonio Pedagogy: Teaching Chicana Lesbian Fiction in a Chicana Feminisms Course at a Predominantly White Institution in the Midwest
Authors: Diaz-Kozlowski Tanya
Published: September 2020

In this essay I extend Chicana/Latina feminist pedagogies to demonstrate using testimonio pedagogy to teach Chicana lesbian fiction: Gulf Dreams and What Night Brings opened up dialogical spaces for students as pensadores to critically examine the impact of racialized gender and sexual normativity within Chicano culture. Exploring the significance of students as pensadores using testimonio pedagogy cultivates pathways of epistemic disobedience that should be understood as responses to institutional power. I suggest testimonio pedagogy mediates marginalization by breaking down the false dichotomy between students and teachers, cultivates feminist consciousness-raising, and refuses hegemonic conceptualizations of schooling.
Social actors in an Intercultural Communication classroom: A discursive lens of intercultural education
Authors: Abdullah Fuad , Lulita -
Published: September 2020

This study focused on how teachers and students as the social actors in an Intercultural Communication (IC) classroom were represented discursively. A video recording transcript of IC classroom activities at a state University in Indonesia was selected as the data source. The data source was rigorously analysed through van Leeuwen’s Socio-semantic inventory of social actors framework (Van Leeuwen, 1996). The main findings show that social actors in IC classroom can be categorised into two main thematic representations, namely positive and negative ones. disclosed that Hamzah as the representative of classroom presenters was represented as victimised, oppressed, intimidated and minoritised actor. Hamzah’s Mathematics teacher was depicted as an intolerant, dehumanising, discriminatory and oppressing actor. Hamzah’s Social Sciences teacher was illustrated as a racial, stereotyping, dominant and provoking actor. The Intercultural Communication teacher was delineated as the actor endeavoring to encourage his students to be tolerant, critical, supportive and open-minded people. Hamzah’s classmates in IC classroom were characterised as sympathetic, supportive, friendly and reactionary actors.

Native-speakerism revisited: Global Englishes, ELT and intercultural communication
Authors: Fang Fan (Gabriel)
Published: September 2020

The English language functions as a global lingua franca, and as the number of non-native speakers of English surpasses the number of native speakers of English, the ideology of native-speakerism is challenged. Viewing from the paradigm of Global Englishes (GE), English is no longer the sole property of its native speakers. This paper first discusses and presents a general picture regarding standard language ideology and the ideology of native-speakerism, and links the notion to how such ideas would exert an influence on teacher recruitment and intercultural communication in English language teaching (ELT). This paper then employs narrative inquiry from Chinese ELT professionals who have education experience abroad to reveal how they negotiate their professional identities in relation to privilege and marginalization when working with native English speaking colleagues. This paper argues for the importance of moving beyond the idealized native speaker model from the GE paradigm to challenge the ideology of native-speakerism in various aspects of ELT, in particular, in expanding circle contexts.
Using six-word stories to trigger EFL learners’ creative writing skills
Authors: Le Phuong
Published: September 2020

There has been a growing volume of six-word stories and related literature available in recent decades. In only six words, the authors are able to tell amazing stories of various types, packed with strong emotions. Inspired by the succinct and thought-provoking language use of these stories, the author has used this valuable source of materials as prompts in promoting EFL learners’ creativity and language development, both at high school and tertiary levels in a semi-structured case study in Vietnam. The article illustrates the different language activities that have been used with two groups of EFL students and their related products. Implications are introduced for their applications in similar educational contexts.
Facilitating reflective practice via Instant Messenger Cooperative Development
Authors: Boon Andrew
Published: September 2020

Reflective practice may be considered an important part of the teaching process. By reflecting on their action, teachers can continually examine their classroom teaching and embrace possibilities for professional growth and change. This article describes how teachers can utilize Instant Messenger Cooperative Development (IMCD) (Boon, 2005, 2007, 2011, 2015); an online framework for reflecting on pedagogical practice. To illustrate IMCD in action, it examines a session in which a teacher explores ways for her learners to recycle and review language learned in previous lessons. The article then discusses the benefits of IMCD as an aid for reflecting on and finding workable solutions to pedagogic puzzles with the hope that readers of the article may go on to utilize IMCD for their own reflective practice purposes.
Revisiting an English extensive reading program in a low “commercial” resources setting
Authors: Manara Christine
Published: September 2020

This paper is a teacher’s critical reflection on the implementation of an Extensive Reading (ER) Program in a teaching context with low resources of commercial graded readers. The paper presents the teacher's dialogue with the ten principles for ER in designing and implementing an ER program. During this process, there are several issues related to the education system and culture as well as the availability of L2 resources. The paper firstly starts with the initial reflection on the previous practices on teaching English reading at a tertiary level to identify the problems. Next, the rationale for initiating an Extensive Reading Course is laid out. Then, samples of teaching activities implemented during the program are presented. Lastly, reflective evaluation of the program is presented with several contextual and pedagogical considerations in working at a low English “commercial” resources context.
Native speakerism (?!): (Re)Considering critical lenses and corresponding implications in the field of English Language Teaching
Authors: Rudolph Nathanael
Published: September 2020

Within English language teaching (ELT), critical scholarship has paid ever-increasing attention to identity, experience and (in)equity, and thus to privilege-marginalization: where it comes from, how and why it manifests, who (potentially) experiences it, and what might be done to address inequity in (and potentially beyond) the profession. This dialogue is intertwined with broader attempts in the field to account for the complexity of identity and interaction in settings around the globe. In this article, I discuss how categorical apprehensions of identity, experience and privilege-marginalization, and approaches to (in)equity, have framed discourse within critical scholarship. I then survey how more recent work has called into question many of the critical “assumptions” (Pennycook, 2001) both shaping and shaped by such theory and inquiry. This scholarship contends that critical lenses predicated upon categories of being, while calling attention to idealized nativeness embedded in ELT, fail to account for the contextualized, sociohistorical negotiation of privilege-marginalization within and transcending communities around the globe. Next, in order to contextualize and unpack these divergent lenses, I provide a review of critical dialogue attending to Japan, both in and beyond ELT, noting in conclusion how privilege-marginalization within ELT is intertwined with the sociohistorical negotiation of “selfhood” and “otherness” pertaining both to Japanese society and Japan and “the world beyond.” I close by briefly commenting on future directions for critical scholarship in ELT, and the challenges facing, and yet to be faced by, its stakeholders.
Prompting second language writers for productive reflection using narrative questioning prompt
Authors: Zacharias Nugrahenny T.
Published: September 2020

This paper aims to introduce a novel form of reflective tool ‘narrative questioning’ to facilitate students’ elaborate and graded reflection in two ESL composition classes in a university in the US. Little has been written about a reflective tool where students need to produce a graded and elaborate reflection and this paper will seek to narrow that gap. Narrative questioning is developed primarily from Barkhuizen and Wette’s (2008) narrative frames. Narrative frames employ “a series of incomplete sentences and blank spaces of varying lengths” (Barkhuizen, 2014, p. 13). Narrative questioning utilizes a series of questions through which students reflected on their perceived learning gain throughout the semester. This paper will first discuss research in narrative reflective tools. Then, it will describe the classroom pedagogical lesson that I conducted to introduce and guide students to write their reflection using narrative questioning. Thirdly, the data gathered through students' reflection and individual interviews of 10 students will be presented and discussed. The data illustrates the different ways of narrative questioning facilitate reflection. Limitations of the narrative questioning elicited from students' interviews will also be presented here along with the pedagogical implication of the study.
“I’m like kentang”: Bilingual Indonesians construction of identity in the era of transnationalism
Authors: Helnywati - , Manara Christine
Published: September 2020

This study looks at bilingual Indonesians who experienced living abroad as sojourners. The study aims to explore their identity experiences and struggles as influenced by their interactions with other language(s) and culture(s). An open-ended questionnaire and interview questions were used to obtain information on the respondents’ short biodata and experiences abroad. Nineteen respondents participated in an online open-ended questionnaire, and a few respondents volunteered to be interviewed. The findings reveal that these bilinguals Indonesian sojourners find it challenging to explain themselves from the monocultural essentialists view of identity. They identify themselves strongly with both their home and host countries and cultures but remaining staying open to new possibilities of identities. Yet, there are also traces of contradicting and conflicting selves of belonging in both cultures.

Memory Deficits in Obsessive-Compulsive Disorder-Changes over the Course of Cognitive-Behaviour Therapy
Authors: Kakra Minal
Published: September 2020

A large body of studies demonstrates memory dysfunction in patients with Obsessive-Compulsive Disorder (OCD). Few trials have only equivocally investigated whether this cognitive dysfunction can be improved by treatment. This study aimed to examine the effect of Cognitive-Behaviour Therapy (CBT) on symptom severity and on verbal and non-verbal memory deficits in patients with OCD as an adjunct to pharmacotherapy. Thirty-five OCD patients were compared with thirty-two controls, matched on age, education and diagnosis, on Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) measuring severity of OCD and Auditory Verbal Learning Test (AVLT) and Complex Figure Test (CFT) assessing the verbal and non-verbal memory respectively at the pre-, middle- and post-treatment assessment.OCD patients showed significantly reduced symptoms after completion of their CBT sessions and their memory dysfunctions also ameliorated in the course of treatment. This study indicates that CBT is an effective treatment with those patients who exhibited significant memory deficits and who were severely affected at the beginning of treatment.
¿Fruto del esfuerzo? Los cambios en las atribuciones sobre pobreza y riqueza en Chile entre 1996 y 2015
Authors: Frei Raimundo , Castillo Juan Carlos , Herrera Rodrigo , Suárez José Ignacio
Published: September 2020

El estudio de las atribuciones de pobreza y riqueza ha tenido un rol central en la literatura sobre la justificación de las desigualdades sociales. La investigación en esta área ha explorado en qué medida se usan razones individualistas versus estructuralistas para explicar por qué ciertas personas logran posiciones más precarias o aventajadas que el resto. En esa línea, este artículo busca dar cuenta de cómo cambian en el tiempo estas razones, en el contexto de una sociedad que ha tenido grandes transformaciones estructurales en las últimas décadas, donde además se mantiene una alta desigualdad de ingresos, como es el caso de la sociedad chilena. Tomando dos encuestas con representatividad nacional de los años 1996 y 2015, los resultados indican en un primer nivel descriptivo que han aumentado las atribuciones individualistas sobre el origen de la pobreza y la riqueza —tales como la falta de esfuerzo y la iniciativa personal— y que han bajado las razones de carácter estructural —como el desempleo o las políticas económicas—. No obstante, a través de un análisis de clases latentes (LCA), se ofrece una segunda aproximación más matizada a este fenómeno, mostrando que la baja de atribuciones estructurales se asocia al aumento de personas que atribuyen tanto razones individualistas como estructurales a la pobreza y riqueza, predominando una combinación de ambas a la hora de significar estos hechos. Estos cambios en los patrones de atribución se discuten en el marco de las transformaciones económicas y culturales de la sociedad chilena.
Asignatura pendiente: Tlatelolco, el teatro y la farsa de la justicia
Authors: Bixler Jacqueline E.
Published: September 2020

El 2 de octubre de 2018 marcó la quincuagésima conmemoración de la masacre del aún desconocido número de estudiantes, transeúntes y otros inocentes en la Plaza de las Tres Culturas de Tlatelolco. Como siempre, el programa cultural del Memorial 68 incluyó varias producciones teatrales, pero esta vez llamó la atención el uso casi exclusivo de la farsa como modo de expresión dramática. La farsa tiende a ser burlona, irreverente y alejada de la realidad, lo que lleva a preguntarse por qué tantos dramaturgos han recurrido a este género antiguo y poco respetado para tratar un capítulo tan doloroso y álgido de la historia mexicana. Este estudio se fundamenta en la teoría de la farsa, la tragedia y la risa y en la percepción extendida de la misma historia mexicana como una farsa. Aunque el uso de la farsa como vehículo para una conmemoración tan significante podría sorprender y hasta ofender, el análisis de cinco obras comprueba que la farsa es últimamente la expresión más realista del ciclo absurdo y sin fin de la historia mexicana, la que ha mostrado repetidamente que se puede matar con impunidad tanto a estudiantes como a todos los que se oponen al orden establecido.

Surgeon-performed ultrasound analysis of the status of the vocal cords of post-thyroidectomy patients with intraoperative neuromonitoring in a tertiary referral center
Authors: Mahalakshmi Vnssvams D. , Mayilvaganan Sabaretnam , Ravisankar M. , Mathialagan Arulalan , Yadav Rajanikant R. , Mishra Prabaker , Agarwal Amit
Published: September 2020

Objectives:

Recurrent laryngeal nerve (RLN) palsy constitutes one of the dreaded complications of thyroid surgery. Sequelae of RLN injury may affect quality of life and can sometimes be life threatening. Pre-, intra-, and post- operative monitoring of the RLN is desirable for safe thyroid surgery. Surgeon-performed transcutaneous laryngeal ultrasound (TLUS) may become a substitute for laryngoscopy in the evaluation of vocal cords after thyroidectomy and may be used for prognostic correlation of intraoperative neurophysiologic monitoring (IONM). In this study, a retrospective cohort of patients who underwent thyroidectomy with monitoring of the RLN by intermittent IONM (I-IONM) was subjected to post-operative ultrasound assessment of vocal cords for the evaluation of RLN integrity.

Material and Methods:

This was a prospective study of a retrospective cohort in a tertiary care endocrine surgery unit. Fifty-six patients who underwent thyroidectomy with RLN monitoring from March 2017 to March 2019 were analyzed. Patients were analyzed during follow-up either when they arrived at the endocrine surgery outpatient department or through a telephone call. All patients underwent pre-operative laryngoscopy, intraoperative monitoring with I-IONM and Nerve Integrity Monitor 3.0 monitor, and post-operative TLUS evaluation of vocal cords.

Results:

Of the 56 patients evaluated in this study, 112 vocal cords and 102 nerves at risk were analyzed. The incidence of vocal palsy was 7.84%. The sensitivity of ultrasonography for vocal cord analysis was 85%, specificity was 95.23%, positive predictive value was 85%, and negative predictive value was 95.23% in that series. The vocal cord visualization rate was 93.5%.

Conclusion:

Surgeon-performed ultrasound may be used to assess RLN integrity in post-thyroidectomy patients to enhance post-operative care.
Digital Technologies in the Modern Music Space

Published: September 2020

At the turn of the 20th—21st centuries, musical culture transformation processes have been actively actualized, which is manifested in the use of digital and visual technologies by musicians, direc tors, producers, visual designers. The stages of transformation of modern musical culture have become relevant precisely for the reason that at the turn of the 20th—21st centuries, mass communication media have begun a process of transition to new digital technologies of implementation and delivery of audiovisual information to modern listeners. Modern specialists, by their activity’s results and its great popularity, prove the relationship bet ween the artistic idea of the work they create and the technical and technological means of its implementation. Thus, in the musical culture of the turn of the 20th—21st centuries, virtual anime characters and Vocaloid performers, whose functioning is actively connected with the use of digital technologies, are particularly relevant and popular. In particular, the creative activities of British musician D. Gahan, Vocaloid anime performers — H. Miku, Kaito, K/DA group, are based on the use of such digitization elements as projection on a translucent screen, expansion of one, often two screens, creation of two- and three-dimensional projection, etc. Animation technologies used in the process of creating modern video clips contribute to the implementation of a wide range of creative and experimental opportunities for directors, in particular, such a technique for creating and broadcasting concert performances as virtual reality has been actualized. Digital technologies also provide opportunities to significantly expand the scope of the range and timbre arsenal of virtual performers, and satisfy a variety of aesthetic tastes of the public.
Chinese Folklore Tales as a Cultural Treasure of the Nation
Authors: Tun Dandan
Published: September 2020

The article examines Chinese folk art, which not only has pronounced national features, but also is a cultural treasure of the nation. Chinese folklore consists of myths, legends, fables, funny stories, fairy tales and tales about life, about animals, as well as works that describe famous historical figures, praise the love of the motherland. The texts clearly demonstrate the motives of admiration for the characters, give positive assessments of labor skills, analyze the characteristics of local traditions, customs and life. The folklore is an integral part of traditional Chinese culture. It educates, shapes the worldview, morals and ethics of the Chinese people. Folklore works become a kind of stage on which the life conflicts of non-heroic existence of an ordinary person with simple cultural interests (for example, communication, participation in rituals, hospitality, etc.) are played out.

The article presents translations of original stories from Chinese into Russian, on the example of which it analyzes the cultural values of Chinese folklore works from the point of view of philosophy. The research is carried out using contextual, linguoculturological methods, as well as methods of analysis and synthesis. The presented research has an interdisciplinary character, because it is performed at the intersection of cultural studies and linguoculturology, folklore studies and translation studies.
Enantiodivergent Non-Linear Effects in Asymmetric Catalysis
Authors: Geiger Yannick , achard thierry , maisse-françois aline , Bellemin-Laponnaz Stephane
Published: September 2020

In this paper, we theoretically discuss the enantiodivergent product formation in asymmetric catalysis, a process in which the sign of the overall product enantiomer switches upon a change of catalyst concentration. The presented model is based on a catalytic system that consists of both discrete and dimeric aggregated metal complexes, in competition and in equilibrium. These concepts were then expanded to a non-enantiopure catalyst, giving rise to enantiodivergent non-linear effects – a special case of a hyperpositive non-linear effects where the product enantiomer’s sign switches upon a change of the catalyst enantiomeric excess. Different cases are considered allowing a discussion of the influence of the parameters governing both models. Finally, we present experimental results that support the enantiodivergence while varying the concentration of enantiopure catalyst or while varying the enantiomeric excess of the catalyst, using chiral N-methylephedrine as a ligand for the enantioselective addition of dimethylzinc to benzaldehyde.

Aims: To evaluate the in vitro antiproliferative, anticholinesterase and anti-phosphodiesterase activities of the sub-extracts of Uvaria alba (family Annonaceae) and explore putative binding mechanisms of its chemical constituents in silico. Main methods: U. alba sub-extracts, obtained by solvent-solvent partition, were subjected to antiproliferative and cytotoxicity screening against chronic myelogenous leukemia (K-562) and human cervical cancer (HeLa) cells, respectively. Inhibitory assays against acetylcholinesterase (AChE) and phosphodiesterase (PDE4 B2) enzymes were also performed. The dichloromethane sub-extract (UaD) was chemically profiled using LC-HR-ESIMS-QToF to identify secondary metabolites 1–18. Molecular docking and molecular dynamics simulations were performed to determine the affinity of the putatively annotated metabolites against PDE4 B2B, AChE, ubiquitin specific peptidase 14 (USP14), and Kelch-like ECH-associated protein 1 (Keap1). In addition, DFT calculations were also performed to demonstrate Michael addition reaction between electrophilic cytotoxic metabolites and Cys151 of the Keap1-BTB domain. Key findings: UaD showed antiproliferative and cytostatic activities against K-562 and HeLa, respectively, and inhibitory activities against AChE and PDE4 B2. Meanwhile, its polyphenolic constituents 3-(3,4-dihydroxybenzyl)-3’,4’,6-trihydroxy-2,4-dimethoxychalcone (8) and grandifloracin (15) showed favorable binding to AChE and Keap1-BTB domain, respectively. The most electrophilic and kinetically stable grandifloracin (15), favorably formed a beta-addition adduct with the Cys151 of Keap1 via Michael addition. The top-ranked ligand-protein complexes attained dynamic stability at 50-ns simulations with high free energy of binding. The top-ranked compounds also conferred favorable in silico pharmacokinetic properties. Significance: The study highlights the role of U. alba secondary metabolites as potential inhibitors against the aforementioned target proteins in an effort to discover new drug leads for cancer and Alzheimer’s.
Mapping Temperature-Dependent Energy-Structure-Property Relationships for Solid Solutions of Inorganic Halide Perovskites
Authors: Yang Jack
Published: September 2020

Formation of solid solutions with complex compositions has been exhaustively adopted in material research for improving chemical and physical properties. This is also the true for halide perovskites, in the hope of further enhancing their stabilities and reducing the toxicities in lead-containing compounds. Replacement of lead with tin, even partially, is a route to achieve the latter goal. However, this has to be compromised with reduction in band gaps as well as structural stabilities. High-throughput statistical samplings over different configurations for random solid solutions have played pivotal roles in guiding the chemical designs of halide perovskite with better stabilities while retaining high photovoltaic efficiencies, but it remains challenging to intuitively and comprehensively understand the intriguing energy-structure-property (ESP) relationships in solid solutions encompassing multiple degrees-of-freedoms. In this work, first--principle dynamic and electronic structure calculations are performed across 51 different compositions of Cs(Pb$_{x}$Sn$_{1-x}$)X$_{3}$ (X=Cl, Br and I), to systematically reveal the compositional and temperature dependent stabilities, vibrational anharmonicities and band gaps in solid solutions of halide perovskites. This is enabled, in particular, by applying a recently proposed `anharmonicity score' that provides a single numerical metric to characterise the structural dynamics in a multi-atomic system. Further combination with unsupervised machine-learning enable us to produce an ESP map to visually correlate the anharmonicity score with structural distortions and energies. However, temperature-dependent variations in band gap energies, which strongly depend on orbital interactions in metal-halide octrahedra, do not necessarily follow the same trend as anharmonicity scores. This work represents our latest developments in applying data--driven approach to establish ESP relationships for guiding the future designs of functional perovskites.

In China, Wuhan in the province of China, COVID-19 a patient suffering from pneumonia was tested and to identify the cause, the throat swab of the patient was tested. On 7th January 2020 WHO declared the identification as COVID-19. And then it was proclaimed as a pandemic. It classically causes a respiratory illness presenting as a mild cough, fever and . However, several investigators have advocated the involvement of the gastrointestinal tract and liver in COVID-19 infection similar to other infections. Further research studies have shown results that are expanding the possibility of transmission because RT-PCR assessment has shown significant evidence for the presence of virus not only in samples but also in stool samples. Studies have shown that virus in stool samples have got positive results even after the illness has resolved, and two respiratory tests were done 24 hours after COVID-19 being tested negative. The review article the different findings of the clinical presentation of COVID-19. It sheds light on the effects of COVID-19 in the gastrointestinal system along with the reasons for the high possibility of transmission of COVID-19 through the route.

Published: September 2020

El objetivo de este artículo es analizar el nivel de los salarios implementados en México en el sector automotor en comparación con sus dos socios comerciales en América del Norte como factor de competencia desleal en el sector automotor. Mediante una metodología descriptiva y documental, así como el uso de datos del INEGI, 2018 y el Automotive Average Salaries, 2020. Los resultados muestran que México tiene el salario más bajo comparado a EEUU y Canadá. México para lograr la competitividad del sector automotor debe revisar su política salarial al alza y enfocarse en desarrollar los factores que impulsen la productividad.
Vozes Griôs no Ensino de Química: Uma proposta de diálogo intercultural

Published: September 2020

Este artigo se configura como uma pesquisa participante, portanto, uma pesquisa pensada para transformação social na qual pesquisador e comunidade intervém juntos em uma demanda da própria comunidade. Cabe salientar que um dos pesquisadores é quilombola. Assim, objetivou-se discutir a seguinte questão: como saberes e fazeres tradicionais de matriz africana dialogam com o ensino de química? Para responder essa questão desenvolvemos um trabalho em comunidades quilombolas (kalungas) do Estado de Goiás, primeiro, ouvindo e aprendendo sobre conhecimentos tradicionais mobilizados pelos Griôs, bem como sobre suas demandas e, em seguida, planejando intervenções pedagógicas intentando estabelecer um diálogo entre esses saberes e a ciência escolar (química). Nossos resultados mostraram ser possível concatenar saberes tradicionais e o conhecimento químico, possibilitando a valorização da ciência de matriz africana culminando na proposição de uma sequência didática e reflexões acerca da mesma que podem orientar a prática docente, especialmente no âmbito da Educação Escolar Quilombola.
Die Einflüsse des prozessorientierten Schreibens auf die Schreibfertigkeit im DaF- Unterricht
Authors: ÇEBİ Rüveyda H.
Published: September 2020

Mit dem Konstruktivismus ist es wichtig geworden, das Lernen zu lernen und dies über die Zeit zu verbreiten. Die Tatsache, dass das Lernen ein langer Prozess ist, der schrittweise voranschreitet und die Nutzung von Strategien erfordert, hat die prozessbasierte Bildung hervorgehoben. In dieser Studie wurde untersucht, ob das prozessbasierte Schreibmodell den Schreiberfolg im deutschen Fremdsprachenunterricht steigert oder nicht. Die Teilnehmer dieser Studie bilden die LehramtstudentInnen im Fach Deutsch der Ondokuz Mayis Universität. Diese Studie, die durch die Bildung einer Versuchs- und einer Kontrollgruppe durchgeführt wurde, ist eine experimentelle Studie. Insgesamt haben 28 StudentInnen teilgenommen, 14 StudentInnen in der Versuchsgruppe und 14 StudentInnen in der Beobachtungsgruppe. In der ersten Woche dieser experimentellen Studie, die zwölf Wochen dauerte, wurde ein Pretest und in der letzten Woche ein Abschlusstest durchgeführt. Während mit der Kontrollgruppe das klassische Schreiben geübt wurde, wurde in der Versuchsgruppe die Methode 4+1 angewendet. Strategien, die für die Schreibfertigkeiten geeignet sind, wurden in die Phasen des Schreibmodells integriert. Mithilfe der Goethe Zertifikat B1 Prüfung, wurde in der ersten Woche das Schreibniveau der beiden Gruppen, ermittelt. Anhand dieser Versuche und deren Ergebnisse, konnte man deutlich erkennen, dass das Lernmodell 4+1, erfolgreicher war. Obwohl in beiden Gruppen das Schreibniveau sich verbessert hat, ist die Gruppe mit 4+1 Schreibmodell statistisch gesehen erfolgreicher. Darüber hinaus haben aber alle StudentInnen individuelle Fortschritte gezeigt.
