Published: March 2022

Apesar do desenvolvimento de estudos sobre evidenciação social e ambiental pela comunidade científica, pouco se tem avançado sobre a incorporação dos Objetivos de Desenvolvimento Sustentável (ODS) como elementos de evidenciação, se fatores endógenos (tamanho e nível de governança corporativa) e exógenos (investimentos em carteiras sustentáveis e internacionalização) afetam de forma diferente o nível de evidenciação dos ODS, se há uma influência direta e indireta destes fatores sobre o desempenho. Nessa perspectiva, esta pesquisa analisa se fatores exógenos e endógenos e a evidenciação relacionada aos ODS afetam o desempenho em companhias abertas listadas na bolsa de valores Brasil, Bolsa, Balcão - [B]3. Para tanto, realizou-se pesquisa quantitativa, de caráter descritivo e por meio de coleta de dados documental em relatórios de sustentabilidade e banco de dados da Economatica®, no período de 2016 a 2018. A partir dos relatórios, foi realizada uma análise de conteúdo, obtendo o número de palavras associadas aos ODS, das quais se originou o índice do nível de evidenciação. Ademais, a análise e validação dos dados se deram pela utilização da regressão linear múltipla e demais técnicas estatísticas pertinentes. Os resultados indicam que fatores endógenos, exógenos e a evidenciação dos ODS influenciam o Market-to-Book das empresas.
El sobreendeudamiento y su impacto en el riesgo de crédito en instituciones microfinancieras peruanas: cajas municipales de ahorro y crédito 2016-2019
Authors: Toledo Concha Emerson Jesús , León Reyes Víctor Manuel
Published: March 2022

La micro y la pequeña empresa en Perú se encuentra en constante desarrollo desde hace cuarenta años. Desde entonces, aparecieron las cajas municipales de ahorro y crédito (CMAC), que tienen autonomía administrativa, financiera y económica, y participan de la descentralización de los servicios financieros. Sin embargo, el crecimiento de la cartera de colocaciones viene acompañado de elevados indicadores de morosidad relacionados al riesgo de crédito de estas instituciones. El objetivo del presente trabajo es analizar si el sobreendeudamiento de clientes, medido como el saldo y número de entidades financieras que tiene el deudor, es una variable que tiene una relación positiva y directa al riesgo de crédito, lo que lleva a constituir mayores provisiones que inciden negativamente en los estados de los resultados de este grupo de instituciones. Esta investigación es de enfoque cuantitativo y correlacional. Los datos recolectados de 48 meses (2016-2019) fueron procesados utilizando la metodología estadística CRISP-DM. Como resultado, se determinó la relación directa del sobreendeudamiento con el riesgo de crédito de las CMAC. La relevancia de esta investigación está dirigida a tomar decisiones estratégicas que permitan tener un mejor control del comportamiento de pago de sus operaciones de crédito y que esto se vea reflejado en mejores resultados económicos.

Authors: Farfan Rodriguez Juliana Carolina , Pérez Velásquez Hugo Alejandro
Published: March 2022

Los pequeños productores de bienes exentos se enfrentan a la disyuntiva de permanecer en la informalidad, en un régimen de no responsabilidad, o de responsabilidad frente al impuesto sobre el valor agregado (IVA) o régimen simple de tributación - SIMPLE. El mayor beneficio fiscal para ellos corresponde a la posibilidad de solicitar la devolución del IVA pagado en adquisición de insumos para su producción, que les representa un mayor costo o gasto. El propósito de la presente investigación es analizar dichos beneficios fiscales de manera comparada en cada uno de los regímenes de tributación que se han establecido en Colombia en el periodo de 1989-2020. Para ello, se utilizó la metodología de derecho comparado en función de los cambios normativos. De igual forma, se hace uso el método de acción participativa, pues posibilita el desarrollo de la investigación en una comunidad de pequeños productores de leche ubicados en el norte de Antioquia; en ese contexto, se identifica el grado de desconocimiento fiscal, el régimen en el que se encuentran, y la capacidad para hacer los cambios administrativos y contables necesarios para acceder a los beneficios fiscales como productores de bienes exentos. Con esto, se puede establecer la opción más beneficiosa para pequeños productores de leche frente al régimen tributario en Colombia.

Published: March 2022

L’objectif de notre recherche se veut une réflexion critique sur le rôle des enseignants de français pour publics spécifiques dans un contexte universitaire libanais post COVID-19. Elle s’inscrit donc dans le prolongement et l’approfondissement des réflexions sur l’enseignement/apprentissage en distanciel suite au confinement imposé depuis mars 2020. Pour mener cette étude, nous avons choisi de nous référer à un outil de modélisation appelé « Arbre de décision de réponse » issu de la théorie des « gestions de crise ». Nous l’avons appliqué au contexte de l’enseignement à distance dispensé au Liban suite à la crise sanitaire afin d’apporter des propositions opérationnelles et immédiates aux enseignants. De plus, nous avons mené conjointement des enquêtes par questionnaires, des entretiens semi-directifs et collecté des témoignages auprès des formateurs du supérieur au Liban. L’analyse jumelée de nos investigations a permis d’établir un état des lieux précis de l’intégration des TIC dans le système universitaire et de faire émerger des besoins prioritaires de formations. En effet, le corps professionnel exige une professionnalisation du métier d’enseignant pour faire face aux nouveaux défis liés à l’usage des TIC. Forts de ce constat, nous proposons un travail novateur et inédit : une proposition d’exploitation pédagogique en lien avec les arts visuels afin d’accompagner les enseignants dans l’enseignement en ligne.

 

The objective of our research is a critical reflection on the role of French teachers for specific audiences following the COVID-19 crisis in the Lebanese universities context. It is therefore part of the extension and deepening of reflections on distance teaching/learning following the lockdown enforced since March 2020. To conduct this study, we chose to refer to a modeling tool called "Decision tree for decision making" from the "crisis management" theory. We have applied it to the context of distance education provided in Lebanon following the health crisis in order to provide operational and immediate proposals to teachers. In addition, we jointly conducted questionnaire surveys, semi-structured interviews and collected testimonies from higher education trainers in Lebanon. The combined analysis of our investigations has made it possible to establish a precise inventory of the integration of ICTs in the university system and to identify priority training needs. Indeed, instructors require a professionalization of the teaching craftsmanship to face the new challenges related to the use of ICT. Based on this observation, we propose an innovative and original work: a proposal for educational exploitation in connection with the visual arts in order to support teachers in online teaching.

Związek jednostek samorządu terytorialnego jako organizator publicznego transportu zbiorowego
Authors: Błażewski Maciej
Published: March 2022

Związki jednostek samorządu terytorialnego mogą posiadać status organizatora publicznego transportu zbiorowego. Realizują one wówczas dwa rodzaje obowiązków: zapewnienie usług przewozowych o charakterze użyteczności publicznej oraz sprawowanie nadzoru regulacyjnego nad działalnością prywatnych przewoźników świadczących usługi przewozowe. Powierzenie wykonania tego zadania związkowi jednostek samorządu terytorialnego służy zwiększeniu sprawności oraz zmniejszeniu kosztochłonności jego wykonania.
Rola Komisji Wspólnej Rządu i Samorządu Terytorialnego w kształtowaniu zasad wsparcia finansowego dla jednostek samorządu terytorialnego w ramach Rządowego Funduszu Inwestycji Lokalnych
Authors: Przedańska Justyna
Published: March 2022

Komisję Wspólną Rządu i Samorządu Terytorialnego ustawowo określono jako forum wypracowywania wspólnego stanowiska rządu i samorządu terytorialnego i jednocześnie zobowiązano ją do opiniowania projektów aktów normatywnych, programów i innych dokumentów rządowych dotyczących problematyki samorządu terytorialnego. W artykule zaprezentowano kazus braku konsultacji z Komisją Wspólną określenia zasad podziału środków z II transzy Rządowego Funduszu Inwestycji Lokalnych, a także przyznanie i podział tych środków wybranym jednostkom samorządu terytorialnego bez ujawnionych zasad czy kryteriów ich otrzymania. W związku z powyższym autorka wyróżniła trzy obszary kluczowe dla funkcjonowania i przyszłości jednostek samorządu terytorialnego: deprecjonowanie roli Komisji Wspólnej w procesie legislacyjnym, narastający problem klientelizmu politycznego, którego przykładem jest właśnie podział środków publicznych określonym jednostkom samorządu terytorialnego według tzw. klucza politycznego, oraz ograniczanie samodzielności finansowej jednostek samorządu terytorialnego w związku z tendencją stopniowej utraty niezależności finansowej na rzecz dotacji celowych z budżetu państwa.
Horyzontalny wymiar zasady subsydiarności — uwagi w kontekście koncepcji decentralizacji i samorządu terytorialnego Tadeusza Bigi
Authors: Wacinkiewicz Daniel
Published: March 2022

Spojrzenie przez pryzmat wyników badań prof. Tadeusza Bigi na temat związków publicznoprawnych na problematykę zasady pomocniczości doskonale obrazuje sprzężenie, w jakim pozostają zasady decentralizacji i subsydiarności. Zasady te znakomicie się uzupełniają, wskazując na określony sposób sprawowania władzy — opartej na zrozumieniu publicznej roli, jaką mogą i powinni odgrywać w życiu publicznym obywatele i tworzone przez nich instytucje; władzy zdolnej do dzielenia się zadaniami publicznymi z podmiotami prywatnymi (obywatelami, ich grupami, wspólnotami, tworzonymi przez nich organizacjami) i wspierającej ich inicjatywy.

Współcześnie obok wymiaru wertykalnego coraz istotniejszą rolę odgrywa również horyzontalny wymiar zasady subsydiarności. Jego istotą jest zapewnienie takiego sposobu wykonywania zadań publicznych, by w jak największym stopniu były one realizowane przez instytucje społeczeństwa obywatelskiego. Organy administracji publicznej, w tym jednostki samorządu terytorialnego, stanowią w takim modelu struktury pośredniczące pomiędzy obywatelami a państwem. Wymaga to stworzenia swoistego „podziału pracy” między sektorem publicznym a obywatelskim.

Authors: Zhao Haoran , Zhou Yanting , Han Ye , Sun Yue , Ren Xiuna , Zhang Zengqiang , Wang Quan
Published: March 2022

In the last few years, the pollution of microplastics in freshwater environments such as rivers, lakes, and reservoirs has aroused widespread concerns. In this review, rich and appropriate data on microplastics, in the freshwater ecosystem of China, was collected. Following this microplastics in surface waters, sediments, and biota, of the freshwater system, were thoroughly analyzed. The results show that microplastics are widespread in the freshwater environment of China. At the same time, the abundance of microplastics is positively correlated with both intensive human activities and urbanization. The risk index of microplastics is relatively high in the water of Yellow River (654 items/L), Yangtze River (9.20 × 105 items/km2), and Pearl River regions (7571 items/m3). The prevalent shapes of microplastics, in water and sediments, are fragments and fibers. Moreover, the particle size of microplastics is mainly less than 2 mm. In fact, PP and PE are found to be the main polymer types in the freshwater environment of China. Bivalves and freshwater fish are the main research objects of microplastics pollution in China. In parallel to that, the abundance of microplastics, in each aquatic organism, varied from a few to a dozen. Additionally, the characteristics of microplastics in organisms are mainly fibers smaller than 1 mm. Fundamentally, the key two sources of microplastics, in the freshwater environment of China, are wastewater discharge and surface runoff. It is noteworthy that microplastics, in a freshwater environment, does not only cause environmental pollution but harms aquatic organisms, too. Finally, microplastics can reach the human body, through the food chain, causing potential health issues.

Lumpur panas Sidoarjo merupakan salah satu bencana luapan lumpur panas yang memiliki dampak signifikan di Indonesia terhitung sejak 29 Mei 2006. Adanya bencana ini banyak menimbulkan kerugian kesehatan, lingkungan hingga ekonomi. Akan tetapi,dibalik kerugian tersebut ternyata terdapat banyak kandungan mineral dalam lumpur luapan yang dapat dimanfaatkan sebagai contoh silika. Tujuan penelitian ini adalah mengetahui kandunganmineral terutama silika dalam lumpur panas Sidoarjo yang dapat berpotensi sebagai sumbersilika sintesis. Sampel diambil pada permukaan lumpur panas Sidoarjo dengan radius 500 m, 1000 m, dan 2000 m dari pusat semburan. Instrumen yang digunakan adalah XRF (X-Ray Fluorescence) dan XRD (X-Ray Diffraction) dimana sampel ditempatkan dalam sampleholder dan diradiasi menggunakan sinar-X. Berdasarkan uji XRF, pada masing-masing radius diperoleh kandungan silika sebesar 45,0% (radius 500 m), 45,3% (radius 1000 m), dan 43,3% (radius 2000 m) yang merupakan senyawa oksida dengan kandungan terbesar. Hasil uji XRD juga menunjukkan kesesuaian dengan hasil uji XRF, dimana fase yang paling dominan dalam lumpur panas Sidoarjo pada semua radius adalah fase kuarsa (SiO2). Berdasarkan kedua hasil ini, dapat disimpulkan bahwa kandungan mineral lumpur panas Sidoarjo pada 3 radius berbeda memiliki kandungan yang relatif sama dan dapat berpotensi sebagai sumber silika yang bermanfaat dalam bidang pangan, industri, hingga dalam bidang katalis.

Published: March 2022

The analysis of polar herbicides by liquid chromatography-tandem mass spectrometry (LC-MS/MS) is challenging due to their complicated interactions. Diquat and paraquat, the bipyridilium group of polar herbicides, are widely used worldwide. This study aimed to optimize analytical conditions of diquat and paraquat in rice matrix using a hydrophilic interaction liquid chromatography column (Obelisc R; 2.1 x 150 mm, 5 µm). The mixtures of acetonitrile and ammonium formate buffer in water were used as mobile phase. All buffer solutions were acidified to a pH of 2.5 using concentrated formic acid. The results showed that 10 mM buffer concentration of ammonium formate was optimal compared to others, including 5, 20, and 50 mM. A mixture of methanol and water (6:4, v/v) containing 1% formic acid was used as an extractable solvent for sample preparation. Method quantitation limit (MQL) of diquat and paraquat in rice samples was 10 µg kg-1. Recoveries at different concentrations (i.e., 20, 50, and 100 µg kg-1) were higher than 70% for diquat, and 80% for paraquat with RSD < 20%, respectively. Diquat and paraquat in rice samples purchased from the local market were lower than MQL, with good recoveries for standard spiked samples.

New holy russian patericon by A. I. Yurievsky: reconstruction project and search for sources
Authors: Chernyshova N. K.
Published: March 2022

The “New holy russian patericon”, created in Siberia (Tobolsk, 1912), is a hagiographic monument that hardly attracted the attention of researchers. The article examines the relationship between A. I. Yurievsky’s work and such outstanding papers by hagiologists and hagiographers of the late XIX - early XX centuries, as the saints by Archbishops Dimitri (Sambikin) and Sergius (Spassky), N. Barsukov, Archimandrite Nicodemus, E. Poselyanin. The Patericon by A. I. Yurievsky is considered, on the one hand, as a project related to the activities of the Tobolsk Brotherhood in the name of Saint Demetrius of Thessalonica, on the other hand, as a part of the All–Russian project to familiarize the Russian Orthodox shrines, which was considered as a mean of countering the process of secularization which seized the Russian society at the beginning of the XX century. The article traces the specific connection of the patericon with the hagiographic works of the epoch: highlights the moments of conceptual influence, as well as their use as sources, in particular, when forming the list of ascetics. The paper presents the content of the available issues of the patericon, lists external characteristics of the publication, chronological frameworks of the collection.The process of A. I. Yurievsky’s working on the patericon text retained in the publications of the Tobolsk Diocesan Bulletin: the writer’s hagiographic works not presented in the patericon were revealed, showing possible directions of his searches.The article concludes that the material presented is only the first step of this topic study. Possible findings of the patericon other texts, use of textual analysis methods will allow to reveal the significance of the monument and more fully represent its place among the hagiographic monuments of the epoch.
Measuring the size, characteristics and consequences of digital work
Authors: O’Reilly Jacqueline , Verdin Rachel
Published: March 2022

This working paper provides a summary assessment of the existing literature and data on digital forms of employment internationally. It illustrates the variability in how it is defined, how it is growing and what kind of risks are associated with these developments. Evaluation of these types of jobs is divided. On one hand, optimists point to the attractions and relative ease in finding employment on digital platforms; on the other hand, more critical perspectives argue that these employment contracts can result in exclusion from social protection systems. The evidence indicates that while overall a relatively small proportion of all employment digital work is growing, both on platforms as well as adoption amongst more traditional companies. The characteristics of digital workers can vary by region and occupation. Overall, they tend to be predominantly younger and more likely male, with a growing number of women albeit in particular occupations. Skills and earnings levels vary but the key issues of disputes is around pay, conditions and employment status. The consequences of this form of work for those with lower skilled digital employment can undermine their social citizenship: they lack comparable employment rights, or when unemployed entitlement to adequate social protection. The potential polarisation effects of digital exclusion and deficits will severely hamper the wider benefits of transparency offered by these technologies. During the pandemic these trends have become more apparent. The imbalance of bargaining power and regulatory governance to bridge gaps in citizenship entitlements undermines the collective potential of policy makers and trade unions to address these challenges. Nevertheless, there is emerging evidence of innovative challenges and contestation of these gaps by both union organisations and national regulators attempts to adapt social protection
Urban Flood Risk Assessment: Integration of Decision Making and Machine Learning
Authors: Taromideh Fereshteh , Fazloula Ramin , Choubin Bahram , Emadi Alireza , Berndtsson Ronny
Published: March 2022

Urban flood risk mapping is an important tool for the mitigation of flooding in view of human activities and climate change. Many developing countries, however, lack sufficiently detailed data to produce reliable risk maps with existing methods. Thus, improved methods are needed that can improve urban flood risk management in regions with scarce hydrological data. Given this, we estimated the flood risk map for Rasht City (Iran), applying a composition of decision-making and machine learning methods. Flood hazard maps were produced applying six state-of-the-art machine learning methods such as classification and regression trees (CART), random forest (RF), boosted regression trees (BRT), multivariate adaptive regression splines (MARS), multivariate discriminant analysis (MDA), and support vector machine (SVM). Flood conditioning parameters applied in modeling were elevation, slope angle, aspect, rainfall, distance to river (DTR), distance to streets (DTS), soil hydrological group (SHG), curve number (CN), distance to urban drainage (DTUD), urban drainage density (UDD), and land use. In total, 93 flood location points were collected from the regional water company of Gilan province combined with field surveys. We used the Analytic Hierarchy Process (AHP) decision-making tool for creating an urban flood vulnerability map, which is according to population density (PD), dwelling quality (DQ), household income (HI), distance to cultural heritage (DTCH), distance to medical centers and hospitals (DTMCH), and land use. Then, the urban flood risk map was derived according to flood vulnerability and flood hazard maps. Evaluation of models was performed using receiver-operator characteristic curve (ROC), accuracy, probability of detection (POD), false alarm ratio (FAR), and precision. The findings showed that the CART method is most accurate method (AUC = 0.947, accuracy = 0.892, POD = 0.867, FAR = 0.071, and precision = 0.929). The results also demonstrated that DTR, UDD, and DTUD played important roles in flood hazard modeling; whereas, the population density was the most significant parameter in vulnerability mapping. These findings indicated that machine learning methods can improve urban flood risk management significantly in regions with limited hydrological data.
Formal Binary Logic, Tidal Forces and the Equivalence Principle
Authors: Döring Holger
Published: March 2022

Mass plays a strange multiple role in classical physics. This results in a difference between gravity and all other forces - a difference that stood at the beginning of Einstein's development of his general theory of relativity. The equivalence principle (EP) deals with homogenious gravitational fields, which, in fact, don‘t exist in nature. There is only an approximation for this field in Einstein-Lift possible for local situations. Nevertheless this EP can be true, because in classical formal binary logic there can be formulated a true conclusion from a wrong premise or assumption.

Objective. To evaluate the levels of human beta-defensin 2 (HBD2), secretory immunoglobulin A (sIgA), and lysozyme in various biological specimens from children with atopic dermatitis and to assess their correlation with the severity of clinical manifestations. Patients and methods. This study included 96 children with atopic dermatitis and 31 healthy controls. We measured serum HBD2, salivary and fecal sIgA, and salivary and fecal lysozyme using special ELISA Kits (CUSABIO, Korea). Results. In children with atopic dermatitis, median levels of serum HBD2 (544 pg/mL [range: 288; 719]), salivary sIgA (120 ng/mL [range: 89.5; 214.5]), fecal sIgA (244 ng/mL [range: 196; 367]), and salivary lysozyme (0.59 ng/ml [range: 0.25; 1.82]) were significantly lower than those in controls (1136 pg/mL [range: 741; 1511], 313 ng/mL [range: 208.5; 356.0], 1582 ng/mL [range: 855; 1710], and 1.65 ng/mL [range: 0.18; 2.58], respectively). We found a strong negative correlation between the SCORAD index and serum HBD2 level (ρ = -0.71, p = 0.005), as well as fecal sIgA (ρ = -0.74, p = 0.032). There was also a negative correlation between the SCORAD index and salivary sIgA (ρ = -0.64, p = 0.032) and salivary lysozyme (ρ = -0.58, p = 0.046). Conclusion. Our findings support the hypothesis that children with atopic dermatitis have reduced production of humoral factors of natural resistance and immunity. The level of HBD2, sIgA, and lysozyme can serve as a biomarker of disease severity. Key words: atopic dermatitis, children, defensins, lysozyme, secretory immunoglobulin A

Postoperative treatment of necrotizing enterocolitis (NEC) in newborns is a challenging problem in pediatric surgery due to high mortality rate among these patients. It is extremely important to search for novel treatments that will not only reduce the death rate, but also improve patients' quality of life. Objective. To improve the outcomes of newborns with NEC in the early postoperative period using cytoflavin, a metabolic antihypoxant/antioxidant. Patients and methods. This study included 77 newborns with NEC operated on in the Department of Neonatal Surgery between 2018 and 2021. All study participants were divided into two groups according to their treatment in the postoperative period. Group 1 (experimental) included 41 NEC patients (53.2%), whereas group 2 (control) included 36 NEC patients (46.8%). The sequential organ failure assessment (SOFA) scale adjusted for neonates was used to evaluate patients' condition. Results. Participants from the experimental group stayed in the intensive care unit for 7.46 ± 1.8 days on average. The maximum SOFA score was 12 and lasted for 3 days in 14 infants (34.1%). Twenty-eight patients had lung ventilation for a mean time of 36.3 ± 4.9 h. Newborns from the control group stayed in the intensive care unit for 10.7 ± 1.2 days on average. Seventeen patients (47.2%) had the maximum SOFA score of 12 for 3 days. The mean duration of lung ventilation was 58.7 ± 4.8 h. Recovery of intestinal transit by 72 h postoperatively was observed in 8 patients from Group 1 and 2 patients from Group 2 (the difference was significant p < 0.05). Conclusion. Hypoxic intestinal damage plays a significant role in NEC development; therefore, metabolic therapy in newborns with NEC ensures a rapid positive effect and faster improvement. Early administration of metabolic therapy with cytoflavin in newborns with NEC reduces the incidence and severity of complications and prevents the progression of multiple organ failure.

» Nutritional assessment is a critical element of routine preoperative assessment and should be approached by an interdisciplinary team that involves the primary care physician, dietitian, and orthopaedist.

» Patients should be stratified on the basis of their nutritional risk, which influences downstream optimization and deficiency reversal.

» The scientific literature indicates that nutritional supplementation affords protection against adverse outcomes and helps functional recovery, even among patients who are not at nutritional risk.

» Published investigations recommend a sufficient preoperative interval (at least 4 weeks) to ensure an adequate nutritional intervention in malnourished patients as opposed to regarding them as nonsurgical candidates.

Published: March 2022

This study aimed to investigate how initiating acts affect refusal strategies realization. The subjects were 45 English Education Program students of Universitas Muhammadiyah Palembang. The study used Discourse Completion Task (DCT) which consisted of 12 situations covering four initiating acts; suggestion, request, offer, and invitations, and the classification of refusal strategy by Beebe et al was also used to categorize refusal strategies realized. The results showed that initiating acts were not insensitive towards the use of direct strategy. However, it has an impact on the realization of indirect strategies and adjuncts. It was also found that both initiating acts and the social status of interlocutors play an important role in producing refusal utterances. Hence, it is highly suggested to introduce initiating acts and social status factors to EFL learners so that they would be able to produce an appropriate refusal depending on the context.

This study aims to describe students’ views on the use of WhatsApp in English Teaching Department classes during the covid-19 pandemic. The impact of the Coronavirus disease 2019 (Covid-19) pandemic is now beginning to spread to the world of education. This condition makes the students and the lecturers used online media or online learning much longer than expected. In the online learning process, WhatsApp is one of the most used applications. This study used qualitative research. The research population was all 270 students of the English Teaching Department of IAIN Batusangkar. The sample involved 168 students by using stratified random sampling technique. Slovin’s formula was used to measure the sample. The research instrument was questionnaires. It was designed in the type of closed-ended and open-ended forms. The questionnaire consisted of 21 statements. Then, to analyze the data from a closed-ended questionnaire, the researchers used Guttman Scale. Meanwhile, to analyze the open-ended questionnaire, the researchers classified students’ responses and then described the results. The finding of the study indicated that students’ views on the use of WhatsApp (WA) in English Teaching Department classes during the covid-19 pandemic mostly positive (73.2%) and the negative responses only (26.8%). Furthermore, students’ views on the use of WA includes WA as media in doing online learning process; WA as an educational media; WA as an evaluation and assessment benchmarks; WA as an application of sharing information; WA as the application to do group discussion; and WA as media to increase literation and to share learning materials. This research implies that WA could be used to do the online learning process because it empirically helps the students to get enthusiastically involved in learning activities.
Characteristics of An Effective EFL Teacher in Indonesia: Expectations and Realities in A Technology-Enhanced Flipped Classroom

Published: March 2022

Previous literature has articulated the contributing role of personality more than teaching competence to be an effective EFL teacher. However, the ideal qualities of an effective EFL teacher in a technology-enhanced flipped English classroom are not much revealed. This paper seeks to compare the ideal teacher’s attitudes and teaching styles with the teacher’s actual practices in a technology-enhanced flipped English classroom from the students’ perceptions. Eighty-three Indonesian undergraduate EFL students majoring in information technology participated in this research. A questionnaire with a checklist and open-ended items was filled out after the students accomplished a 16-week English course. The results showed that an effective EFL teacher in a technology-enhanced flipped English classroom should possess and exemplify the attitudes of patience, friendliness, and niceness, as perceived by the students. Most students also envisaged that an effective EFL teacher in such a learning context can use various, innovative, easy-to-follow methods and employ English and Indonesian alternately. The realities generally accorded with the students’ expectations. More students favored the use of various kinds of instructional technology by the teacher. However, the teacher was less favored for being too serious, not being open to students, giving unclear instructions for doing the assignments, and giving less guidance to use the educational technology
