INDEPENDENT LEARNING IN ENGLISH ONLINE CLASS DURING COVID-19 PANDEMIC: STUDENTS PERCEPTIONS AND ITS CHALLENGES
Authors: Nagauleng Andi Mukarramah , Waris Ahmad Mustamir
Published: June 2023

The spread of Covid-19 in Indonesia forces teachers and students to conduct the online learning-teaching process independently. Online learning is carried out to protect teachers-students and reduce the number of people affected by the virus. Thus, this present study aims to discuss how independent learning in online English class put into practice at school, discover students’ perceptions of independent learning in online English classes and its challenges during the Covid-19 pandemic. This present study relays on mixed methods research design. Qualitative and Quantitative data were collected through a survey using a google form. Qualitative data were analyzed by coding, classifying, explaining, and concluding. Meanwhile, quantitative data were analyzed using the Likert scale method through SPSS ver. 23. The results show that in the learning-teaching process during the covid-19 pandemic, students learn independently using learning-teaching materials provided by English teachers. Besides, students use media such as YouTube to help them understand the material given by teachers. Students claim that independent online English learning is ineffective since students find difficulties in understanding materials. Although students use technology to support the learning-teaching process, it does not work well since the internet connection is unstable and internet quotas are limited. Therefore, teachers should manage independent online learning properly to enable students to achieve the goal of the learning-teaching process. Teachers should organize and control the learning-teaching process according to current needs; planning, implementation, and assessment.

Published: June 2023

Teaching materials are needed as learning resources that should be adapted based on students’ conditions. The contextual approach is a suitable approach to meet the needs of students in learning in order the improvement of learning outcomes can be carried out. Appreciation of poetry as a course in the department of Indonesian language and literature education requires development to obtain learning outcomes and adjustments on student conditions and the times. The development of such a theory has led this research to develop the design of teaching materials as an intellectual framework and the basis of reference from teaching materials for poetry appreciation. This research uses a qualitative approach and descriptive methods to define needs from the point of view of students, lecturers, and experts in the field of poetry appreciation. The results of the study showed the need in terms of content and strengthening the theory. In the elements of the book, the graphics and the appearance or layout are important to attract interest. Supporting elements such as short and long videos and expert opinions are needed by students. Laboratory facilities and art spaces are representative places to apply more contextual learning. This research is prepared for the need of development and for other researchers who need analysis and framework of teaching materials from the book elements, learning outcomes, and supporting components.

LEXICOSTATISTICS OF MALAY AND MALAGASY LANGUAGES: COMPARATIVE HISTORICAL LINGUISTIC STUDY
Authors: Anayati Wan , Wardana Muhammad Kiki , Mayasari Mayasari , Purwarno Purwarno
Published: June 2023

This study examines the kinship of the Malay language and the Malagasy language. These two languages come from the same proto language, namely Proto Austronesian (PAN). Departing from the researchers’ assumptions about the linguistic relationship both at the phoneme and morpheme levels, there is a close kinship system or relationship between these two languages. Even though they are geographically and geo-politically separated, preliminary research on these two languages shows several universal features, one of which is that both languages are agglutinative languages. Therefore, this study is an attempt to find empirical evidence about the separation time between Malay and Malagasy by using language grouping methods and lexicostatistical techniques. The first stage, the researchers collect 300 basic vocabularies compiled by Swadesh (1995). The method used in providing the data is the referential method, while the technique used is the note-taking technique. Second, the researchers determine which pairs of the two languages are cognate languages. Third, the researchers calculate the age and separation time of the two languages. Fourth, the researchers calculate the error term to determine a more precise separation time. The result of this research indicates that Malay and Malagasy were a single language at 4223-3951 thousand years ago and began to separate from their proto languages in 2201-1929 BC.

SEMANTIC REVIEW ON THE REFORMULATION AS THE FORM OF CLARIFICATION IN APPOSITIONAL CONSTRUCTIONS
Authors: Gunawan Hero , Sari Puspita
Published: June 2023

This research-based article discusses appositives containing reformulation which is very important in the context of meaning particularly in the form of clarification to the anchor as the antecedent. This reformulation is viewed from the two aspects, i.e., semantic equivalence and coreference. Therefore, this research serves two aims: 1) to elucidate the forms of clarification provided by reformulation as semantic equivalence that makes anchors more comprehensible, and 2) to elaborate whether reformulation and its anchor are coreferential in the appositional constructions. The data sources are taken from English printed media within three levels of distributional coverage, i.e., national, regional and international coverage. The data are analysed through employing the method of qualitative research, that is, the method presenting descriptive data, both written and oral data. To analyse such descriptive data, the distributional method of analysis with the two techniques is used, namely, extracting techniques, and inserting techniques. The results of this research uncover that 1) the forms of clarification provided by the reformulation cover: a) metaphorical expression, b) factual knowledge, c) expression of revision, d) simplified expression, e) short forms (acronyms), f) emphasis through negative reformulation, and g) equivalence in other language; and 1) not all reformulations have coreferences. All of the reformulation forms are given to make the anchor more comprehensible.

Published: June 2023

COVID-19 outbreak that has shifted face-to-face (f2f) to force­d remote learning challenged the CLIL Science teacher to thrive in a new teaching form. The f2f adaptation of the virtual meeting using video conferencing software has driven the teacher to have an effective and accessible synchronous learning environment, in addition to the asynchronous one. This research was a narrative inquiry participated by a CLIL Science teacher teaching the first-grader in a small town in Indonesia. By employing an in-depth interview, the data were collected and then analyzed by emotional geography frameworks. The findings showcased the f2f adaptations made by the teacher that synchronous mode of delivery was conducted in thirty minutes by careful attention on CLIL frameworks, the language (s) use, and students’ engagement. Her sociocultural, moral, professional and political geographies led her to decide what to do to make the students learning feasible. An implication of this is the possibility that the experience of how the CLIL Science teacher taught the young learners using English would be a new insight for other teachers in dealing with real-time live lesson delivery during the COVID-19 outbreak.

This paper reported a research project on using drama in English as foreign language (EFL) classroom for exploring students’ knowledge and learning. The exploration aimed at understanding the students’ interests, abilities and motivations. Then, we also observed the teacher’s perceptions in the classrooms during the implementation of the drama for the students. In the study, we find that students show their good engagement and comprehension abilities. However, the perceptions of the teachers varied on the several aspects of the students’ preparation and performance. Further, their perceptions reflect the pedagogical context offering possibilities for cultural production in language learning. The research results underline how the drama can be used to construct the abilities for early language learners especially for social engagement and language comprehension.

Translation ethics in the light of the Chinese ecological model of translation
Authors: Li Tszyasin
Published: June 2023

Translation is a kind of cross-cultural interaction of people, and ethical relations have existed since the emergence of human relations. The main task of the translator is to coordinate relations between different cultures, languages and subjects of translation, therefore, the role of the translator is closely linked to ethics from the very beginning of the translation activity, and the activities and duties of the translator are carried out ethically consciously. The purpose of the study is to describe the study of translation ethics in China and a detailed study of translation ethics from the point of view of the ecological model of translation. The author shows how erroneous translations can be caused by the irresponsible behavior of translators due to their incorrect ethical views and values. In this process, the author uses an analytical method and a comparative method. According to the results of the study, it was concluded that, theoretically, it is necessary to continue improving the value and ethical aspects of the ecological model of translation; as for the existing problem of incorrect translation, according to the author, efforts should be made to create a beneficial cycle of translation ecology. Against the background of numerous research perspectives, the science of translation attaches importance to translators, returns to ethics and focuses on relationships and behavior in the system of moral values. The results of the study are important for the improvement of the Chinese translation, the development of translation theory and the training of translators.
Online cinemas as new media
Authors: Murzina Ol'ga Viktorovna , Grabel'nikov Aleksandr Anatol'evich , Tsitsinov Andrei Yur'evich
Published: June 2023

The subject of the study is online cinemas (streaming services, streaming platforms), understood by the authors of this study as new media. The object of the study is a set of features of new media, considered on the basis of streaming services on the Russian market. The authors consider in detail such aspects of the topic as the features of the content of online cinemas, their correlation with new media and format television, building a user trajectory of content and the possibility of posting user reviews. Particular attention is paid to the transformation of format television into neotelevision using the tools of modern technologies and the capabilities of convergent online platforms with content diversification. The main conclusions of the study are the classification of online cinemas as an intermediate variant of new media: the renovation of the features of traditional media on a new platform. Unlike traditional cinemas, which do not position themselves as media platforms, online cinemas allow viewing news content, promptly tracking events in the world and at the same time viewing entertainment and educational content in a user-friendly mode. A special contribution of the authors to the study of the topic is an appeal to online cinemas from the perspective of journalism and media, which was not previously presented in Russian science. The novelty of the research lies in the consideration of streaming services as part of the media and as part of a modern media system that includes both fundamentally new media and the renovation of existing formats.
Homo loquens: values in the structure of narrative identity
Authors: Babich Vladimir Vladimirovich
Published: June 2023

The relationship between narrative identity and values is considered. It is argued that the problem of the relationship and balance between the experience of experiencing: values, a multidirectional spectrum of desires, emotions and actions, is inseparable from the issue of self-determination of the subject. The presented analysis is based on the concept of the dynamics of narrative changes by Ch.M. Taylor "the best possible articulation of experience" (Best Account) and the concept of M.M. Bakhtin. Building a narrative identity is impossible without reference to values that serve as the foundations of intentional states, orientations and motives that determine behavior. The necessity of values for our self-description reveals their reality. Reflection is a necessary condition for the ontologization of values, defining the difference between "values" and "norms", "desires" and "preferences". In the structure of narrative identity, value is not any desire or preference, but only one that needs justification (rational articulation). The empirical consequence of rational articulation is the formation of a common narrative or the formation of a common language that facilitates the justification of values, which is a condition for the emergence of solidarity. The hermeneutic circle is considered as a model for the formation and transformation of narrative identity. The presented model describes the interaction between the subject's articulations and his pre-reflexive experience of the emotional experience of values, correlating these elements with the existing spectrum of axiological interpretations. The hermeneutic circle reveals the possibility of coordinating in the subject different levels of existence of values, from the point of view of overcoming the contradictions between the individual and the collective: desires, emotions, values and actions. It is concluded that values are embedded in the structure of narrative identity in several ways: they form the content of the narrative, reinforce ideas about ideals through narrative, and form intentions.
On the first experiences of creating feature films in the Republic of Bashkortostan in the mid-1990s
Authors: Baiturina Diana Uralovna
Published: June 2023

The subject of the article is a film of a Bashkir film director -"Glass Passenger" by Bulat Yusupov. The author of the article carries out an archetypal, semiotic and hermeneutic analysis of the cinematographic text. The first one is the study of mythological elements within the film. It will show us the presence in the work of elements of the national myth and their connection with the literary archetypes of Jung. The second, semiotic, takes place under the conditions of isolating signs from relationships within the whole structure that defines a film work as a kind of a media text. And the third, hermeneutic, is based on the traditions of cinema interpretation in the intertextual interaction of all literary texts. The scientific novelty of the research lies in the systematic, comprehensive study of the Bashkir cinema, in comparison with the samples of the world artistic culture; in identifying the key features of an individual film that has not previously been subjected to detailed scientific study. The film refers the viewer to the images of Bashkir mythology. The analysis carried out reveals in the media text the trends in the creation of feature films in Bashkortostan.
Entre o um e o múltiplo:
Authors: Davidans Sversutti William
Published: June 2023

Neste artigo, abordaremos algumas das críticas aristotélicas em relação à Teoria das Formas platônica quanto ao argumento do “um sobre o múltiplo” assim como se apresentam em algumas passagens do Livro I da Metafísica e na obra Peri Ideon. Parece-nos que Aristóteles vê uma separação (chorismos) entre a ideia (una e eterna) e os particulares sensíveis (múltiplos e em constante devir) na teoria platônica, o que o leva a levantar uma forte oposição à mesma naqueles dois textos. Com o objetivo de levantar alguns pontos questionáveis da interpretação aristotélica sobre a posição de Platão frente essa questão, procura-se, primeiramente, discutir pontualmente aquelas passagens, para depois problematizar a interpretação aristotélica do pensamento platônico.

Authors: Hamzah Abdulaziz , Alharbi Abdullah S. , Abdulhamid Ahmed S. , Turkistani Alaa Nabil , Aref Mohmmed Hani
Published: June 2023

Background:

This study provides a comprehensive overview of the management of postoperative vasospasm after skull base surgeries. This phenomenon is rare but can be of serious sequelae.

Methods:

Medline, Embase, and PubMed Central were searched, along with examining the references of the included studies. Only case reports and series that reported vasospasm following a skull base pathology were incorporated. Cases with pathologies other than skull base, subarachnoid hemorrhage, aneurysm, and reversible cerebral vasoconstriction syndrome were excluded from the study. Quantitative data were presented as mean (Standard Deviation) or median (range), accordingly, while qualitative data were presented as frequency (percentage). Chi- square test and one-way analysis of variance were used to assess for any association between the different factors and patient outcomes.

Results:

We had a total of 42 cases extracted from the literature. The mean age was 40.1 (±16.1) with approximately equal males and females (19 [45.2%] and 23 [54.8%], respectively). The time to develop vasospasm after the surgery was 7 days (±3.7). Most of the cases were diagnosed by either angiogram or magnetic resonance angiography. Seventeen of the 42 patients had pituitary adenoma as the pathology. Anterior circulation was nearly affected in all patients. For management, most patients received pharmacological with supportive management. Twenty-three patients had an incomplete recovery as a result of vasospasm.

Conclusion:

Vasospasm following skull base operations can affect males and females, and most patients in this review were middle-aged adults. The outcome of patients varies; however, most patients did not achieve a full recovery. There was no correlation between any factors and the outcome.
A RoundD-like Roundabout Scenario in CARLA Simulator
Authors: Nadar Ali , Lafon Mathis , Härri Jérôme
Published: June 2023

Evaluating the challenges and opportunities of cooperative autonomous vehicles (CAV) require an adapted simulation methodology reproducing realistic driving and sensory contexts. In this paper, we propose a RounD-like CARLA scenario reproducing in CARLA the driving context recorded in the RounD dataset. We focus in particular on roundabout scenarios, as they are considered particularly challenging for CAV. We present the methodology followed to generate the CARLA scenario and describe challenges to reproduce trajectories corresponding to RounD. Origin and destination of vehicles, waypoint and speed are extracted from RounD for CARLA vehicles to closely reproduce the driving patterns observed in RounD. The benefit of such scenario are manyfold, such as evaluating control algorithms of CAVs, deep AI reinforcement learning, or vehicular sensor data sampling under realistic driving contexts. It notably will reduce the gap of AI mechanisms for CAV between simulation scenarios and realistic conditions.
ESG development of Russian companies: a focus on the markets of the Asian-Pacific region and the Middle East
Authors: Starodubtseva E. B. , Trachenko M. B.
Published: June 2023

The article considers the tasks of the ESG transformation in Russian companies. Particular attention is paid to the analysis of the main problems and development trends of the ESG agenda in the regions where Russian business is reorienting in conditions of the sanctions’ pressure, namely, the countries of the Asia-Pacific region and the Middle East. The expediency of adopting a single national standard for non-financial reporting, which includes a system of indicators taking into account industry specifics and allows optimizing partnerships with Eastern counterparties, is substantiated. It is proposed to create an ESG portal under the auspices of VEB.RF as the main methodological center for sustainable development in the Russian Federation, which will allow Russian exporters and importers to receive up-to-date information on the ESG requirements of potential foreign counterparties. The basis for financing for the creation and development of such a portal should be both federal budget funds and private financing, which corresponds to the interests of both parties. Thus, the state encourages the development of export relations with foreign companies, and the private sector gets access to regularly updated information to expand foreign economic activity in new markets. Further research will be aimed at developing recommendations for Russian exporters and importers focusing on the markets of the Asia-Pacific region and the Middle East in the context of specific jurisdictions and industries.

Psychological aspects of the class teacher’s professional activities
Authors: Kochemasova L. A. , Zhuleva M. I.
Published: June 2023

The article is devoted to determining the need for the formation of a system of knowledge and skills in the field of psychology among students of a pedagogical university, among future classroom teachers, taking into account modern trends in education. The article presents the results of a psychological and pedagogical study conducted to identify the psychological climate of the class collective, in which 28 students of the 5th grade from the MOAU “SOSH No. 87” of Orenburg took part. The following methods were used in the course of the study: analysis and synthesis, questionnaire (survey), observation. The study revealed the need to form a system of knowledge and skills in the field of psychology in future teachers. The results obtained suggest that distance learning has a negative impact on the formation process of a class collective and prevents its cohesion, which indicates the need to study psychological disciplines at a pedagogical university. This work may be of interest to students of pedagogical colleges and universities, employees of educational organizations, since with the introduction of the distance learning format, the problem of establishing a favorable psychological climate in the classroom, which has not lost its relevance for a long time, has significantly become aggravated.
The features’ analysis of modern economic crises
Authors: Esina O. I. , Sirazhdinov R. Zh.
Published: June 2023

As evidenced by the historical digression, economic crises are an integral element in the development of the world economy. The overproduction of goods was considered as the main cause of crises, that is, the volume of products produced by aggregate suppliers exceeded aggregate demand. The significant expansion of exports has led to the internationalization of not only world trade, but also the production of goods and the creation of new supply chains, which caused the vulnerability of the entire chain of enterprises connected technologically in many countries. The aim of the work is to study the dynamics of economic crises, to identify their causes and consequences for the world economy. The paper examines the economic crises that have occurred in different countries and the change in their nature. The methods of comparison and statistical analysis were used as research tools in the work. As the analysis carried out in the work has shown, economic crises from partial, covering individual countries, turn into global ones. Moreover, the depth and scale of economic crises are increasing despite the created mathematical tools and a significant increase in computing power. The analysis allows us to draw conclusions about the further regionalization of world trade and production. In addition, these processes are objective and do not depend on the current distribution of economic potential.
Ground State Orbital Analysis Predicts S1 Charge Transfer in Donor–Acceptor Materials
Authors: Abou Taka Ali , Herbert John M. , McCaslin Laura M.
Published: June 2023

Donor-acceptor (D-A) materials, such as D-A co-crystals and D-A copolymers, can exhibit a wide range of unique photophysical properties with applications in next-generation optoelectronics. Identifying structure-function relationships to predict properties of materials from molecular features is a key challenge in the development of rational design principles. In this communication we present a novel metric for predicting the degree of charge transfer (DCT) in the S1 electronic state of D-A materials, using ground state orbital analysis. This metric computes the average of two quantities: (1) the degree of similarity between the highest occupied molecular orbital (HOMO) in the donor molecule and the D-A complex and (2) the degree of similarity between the lowest occupied molecular orbital (LUMO) in the acceptor molecule and the D-A complex. We demonstrate a linear relationship between this similarity metric and the DCT in the S1 state (HOMO → LUMO transition) for a data set of 31 D-A dimers. We discuss the integration of this novel orbital structure-function relationship into high-throughput screening methods and suggest best practices for choosing both molecular geometries and methods for computing the DCT.

Substrate positioning dynamics (SPD), which orients the substrate to a reactive conformation in the active site, is critical in mediating enzyme catalysis. However, given that conformational changes often accompany variations in the enzyme interior electrostatics, it remains unknown whether SPD contains a non-electrostatic component that independently mediates catalysis, or originates primarily from perturbation of enzyme interior electrostatics. This study integrated computational and experimental approaches to investigate the non-electrostatic component of SPD using Kemp eliminase (KE) as a model enzyme. A molecular dynamics-derived descriptor, substrate positioning index (SPI), was used to quantify the impact of protein dynamics on substrate positioning. Using high throughput enzyme modeling, we selected 7 KE variants for kinetic assessment – these variants involved significantly different SPD but similar interior enzyme electrostatics. We observed a valley-shaped, two-segment piecewise linear correlation between the experimentally characterized activation free energies and SPI values. The trend is further validated using previously reported kinetic data. An optimal SPI value, corresponding to the lowest activation free energy, was observed for R154W, a surface mutation located distantly from the active site. Compared to the wild type, R154W involves favorable SPD that increases the proportion of reactive conformations for substrate deprotonation. These results indicate the presence of the non-electrostatic component of SPD, a concrete factor that mediates catalysis by tuning the population of reactive conformation.

Per- and polyfluoroalkyl substances (PFAS) are of high concern, with calls to regulate these as a class. In 2021, the Organisation for Economic Co-operation and Development (OECD) revised the definition of PFAS to include any chemical containing at least one saturated CF2 or CF3 moiety. The consequence is that one of the largest open chemical collections, PubChem, with 115 million compounds, now contains over 7 million PFAS under this revised definition. These numbers are several orders of magnitude higher than previously established PFAS lists (typically thousands of entries) and pose an incredible challenge to researchers and computational workflows alike. This article describes a dynamic, openly accessible effort to navigate and explore the >7 million PFAS and >21 million fluorinated compounds (17 June 2023) in PubChem by establishing the “PFAS and Fluorinated Compounds in PubChem” Classification Browser (or “PubChem PFAS Tree”). A total of 36,500 nodes support browsing of the content according to several categories, including classification, structural properties, regulatory status, or presence in existing PFAS suspect lists. Additional annotation and associated data can be used to create subsets (and thus manageable suspect lists or databases) of interest for a wide range of environmental, regulatory, exposomics and other applications.

Fluoride (F–) is a unique analyte because when in small quantities, it is beneficial and harmful when in larger or negligible quantities, leaving it essential for dual-purpose detection and removal from a water sample to prevent fluoride-caused health risks. F– detection and removal using organic molecules and hybrid materials are extensively reported in the literature, but very few reports discuss dual-purpose detection and removal. Functional nanomaterials (FNM) based on nanoparticles, metal-organic frameworks, and carbon dots conjugated with fluorophore moiety are largely used for these purposes. Functional groups present on nanomaterial surfaces exhibited various types of interactions such as agglomeration, electrostatic, hydrogen bonding, ion exchange, coordination and π-π stacking interactions enabling dual-purpose detection and removal of F–. These materials offer unique properties such as tunable pore structure, size, and morphology coupled with large surface area and high thermal/chemical stability. Further, this perspective review discusses prospects for sustainable technologies in addition to describing the advantages and disadvantages of using FNM based on its optical properties as well as the removal efficiency. We believe this is the first account that summarizes the single FNM that can be used for both the selective detection of F– in aqueous media as well as its efficient removal.

The tertiary amine-based cage molecules are high-value intricate synthetic targets and their succinct stereoselective synthesis with broad substrate generality remains rare. Herein, we report for the first time the union of two distinct readily available azolium salts as an efficient synthetic platform to access natural products like tertiary amine cage frameworks under mild conditions. The strategy combines the masked nucleophilic and electrophilic properties of isoquinolinium salts and pyridinium salts, respectively, and avails double dearomatization guided inverse electron demand (4+2) or (3+2) annulation in a highly regio- and diastereoselective manner to materialize the nitrogen cage motifs including the aza-polycyclic core of hetisine-type alkaloids in high yields (50 examples). To streamline further, we delineated a five-component as well as a four-component one-pot sequential addition strategy without compromising the selectivity, emphasizing the efficient utilization of resources and the pot economy. Our methodology harvests two new rings and four new bonds in a single operation and transforms from flat-aromatic compounds into structurally unprecedented three-dimensional architectures with contiguous stereocenters as a single diastereomer.

As the population increases in the world, the ratio of health care takers is rapidly decreasing. Therefore, there is an urgent need to create new technologies to monitor the physical and mental health of people during their daily life. In particular, negative mental states like depression and anxiety are big problems in modern societies, usually due to stressful situations during every day activities including work. This paper presents a machine learning approach for stress detection on people using wearable physiological sensors with the final aim of improving their quality of life. The presented technique can monitor the state of the subject continuously and classify it into”stressful” or”non stressful” situations. Our classification results show that this method is a good starting point towards real-time stress detection Stress is a natural reaction to various stress-inducing factors which can lead to physiological and behavioural changes. If persists for a longer period, stress can cause harmful effects on our body. Stress is a major concern in our day-to-day life. The human environments including worksite, home or society can induce stress on an individual to some extent. There are many ways that our body can react to stress, these reactions are mainly classified to either physiological reactions which includes the ‘fight or flight’ response by the Autonomous nervous system (ANS) of our body or behavioural reactions which includes defensive behaviour, days functional and expressive behaviour, the body sensors along with the concept of the Internet of Things can provide rich information about one’s mental and physical health.
