EFL students’ preferences on digital platforms during emergency remote teaching: Video Conference, LMS, or Messenger Application?
Authors: M. Amin Fakhrurrazi , Sundari Hanna 
Published: September 2020

The use of technology in language learning has extensively expanded in line with the advancement of technology itself. However, the investigation into the implementation of video conferences, learning management systems, and mobile applications, particularly during the emergency remote teaching/the Covid-19 pandemic, is still lacking. This paper presents survey data from three groups of Indonesian EFL students using three different digital learning platforms: Cisco WebEx Meeting video conferencing, Google Classroom learning management system (LMS), and WhatsApp mobile messenger application. The purpose of the study was to determine the students’ preferences including their perception and point of views on using the platforms and application during the remote teaching situation. There were 140 EFL students from two universities/institutes in Jakarta and Aceh to take part as the participants. The instrument was a questionnaire based on criteria of CALL evaluation, and descriptive analysis using percentages and thematic analysis was applied. The findings show that the Cisco WebEx Meeting, Google Classroom, and WhatsApp gained highly positive agreement on all criteria. Specifically, the Cisco WebEx meeting got the highest scores on authenticity and meaning focus. Meanwhile, for GC and WhatsApp, the criteria on language learning potential, meaning focus and authenticity achieved the highest scores. Moreover, WhatsApp is the most preferred among others in meaning focus, learner fit, positive impact, and practicality. However, the three digital platforms received the lowest score on a positive impact at each group-participant. It seemingly indicates that they thought the full online digital learning system they experienced during ERT is less preferable than face-to-face learning.
Critical Discourse The Epistemology of Muhammad Syahrur's Ijtihad
Authors: Maulana Asep Suraya 
Published: September 2020

Penawaran Syahrur terhadap sikap skriptualis-literalis dan modernis-sekularis dari masyarakat Islam saat ini adalah kembali kepada Inzal (al-Qurâ€™an), teks asli dari wahyu Allah yang disampaikan kepada Nabi. Kajian ini menggunakan pendekatan kualitatif, untuk menganalisis epistemologi ijtihad Syahrur. Hasil kajian menunjukkan bahwa, pemikrian Syahrur mengenai epistimologi bersumber dari alam materi yang berada di luar eksistensi manusia. Syahrur dalam menafsirkan ayat-ayat ahkam, masih sepakat untuk menjaga kemurnian ajaran al-Qurâ€™an yang shalah likulli zaman wa makan. Menurut Syahrur, tumpuan kebenaran berdasarkan tiga pilar, yaitu: wahyu, akal, dan realitas. Perpaduan antara wahyu, akal dan indera akan mengahasilkan pengetahuan hukum Islam yang baru dan modern. Penawaran Syahrur, tentang teori historisitas ilmiah, hermeneutika lingustik dan dialektika Marxis, menunjukkan upaya mendekonstruksi ilmu pengetahuan yang sudah paten dalam penerapan hukum Islam. Perbedaan konsep ijtihad ushul fiqh klasik dengan konsep ijtihad Syahrur, antara lain: 1) menempatkan ijtihad pada posisi vital bagi hukum Islam modern; 2). konsep ijtihad Syahrur hanya pada tahapan menghalalkan atau mengharamkan sesuatu, karena merupakan hak prerogratif Allah; 3). konsep ijtihad Syahrur mengharuskan prestasi ilmiah dan sistem pengetahuan modern; 4). konsep ijtihad Syahrur membolehkan ijtihad terhadap seluruh teks hukum, walaupun oleh para ulama dipandang qathâ€™i; dan 5). konsep ijtihad Syahru dapat dilakukan secara individual.

A Non-Linear Temperature Compensation Model for Improving the Measurement Accuracy of an Inductive Proximity Sensor and Its Application-Specific Integrated Circuit Implementation
Authors: Wang Li , Tao Hui-Bin , Dong Hang , Shao Zhi-Biao , Wang Fei 
Published: September 2020

The non-linear characteristic of a non-contacting Inductive Proximity Sensor (IPS) with the temperature affects the computation accuracy when measuring the target distance in real time. The linear model based method for distance estimation shows a large deviation at a low temperature. Accordingly, this paper presents a non-linear measurement model, which computes the target distance accurately in real time within a wide temperature range from −55 °C to 125 °C. By revisiting the temperature effect on the IPS system, this paper considers the non-linear characteristic of the IPS measurement system due to the change of temperature. The proposed model adopts a non-linear polynomial algorithm rather than the simple linear Look-Up Table (LUT) method, which provides more accurate distance estimation compared to the previous work. The introduced model is fabricated in a 0.18 μm Complementary Metal Oxide Semiconductor (CMOS) process and packaged in a CQFN40. For the most commonly used sensing distance of 4 mm, the computed distance deviation of the Application-Specific Integrated Circuit (ASIC) chips falls within the range of [−0.2,0.2] mm. According to the test results of the ASIC chips, this non-linear temperature compensation model successfully achieves real-time and high-accuracy computation within a wide temperature range with low hardware resource consumption.

Background
Transplant practices related to use of organs from hepatitis C virus–infected donors (DHCV+) is evolving rapidly.

Methods
We surveyed US kidney transplant programs by email and professional society LISTSERV postings between July 2019 and January 2020 to assess attitudes, management strategies, and barriers related to use of viremic (nucleic acid testing positive [NAT+]) donor organs in recipients who are not infected with HCV.

Results
Staff at 112 unique programs responded, representing 54% of US adult kidney transplant programs and 69% of adult deceased donor kidney transplant volume in 2019. Most survey respondents were transplant nephrologists (46%) or surgeons (43%). Among the responding programs, 67% currently transplant DHCV antibody+/NAT− organs under a clinical protocol or as standard of care. By comparison, only 58% offer DHCV NAT+ kidney transplant to recipients who are HCV−, including 35% under clinical protocols, 14% as standard of care, and 9% under research protocols. After transplant of DHCV NAT+ organs to recipients who are uninfected, 53% start direct-acting antiviral agent (DAA) therapy after discharge and documented viremia. Viral monitoring protocols after DHCV NAT+ to HCV uninfected recipient kidney transplantation varied substantially. 56% of programs performing these transplants report having an institutional plan to provide DAA treatment if declined by the recipient’s insurance. Respondents felt a mean decrease in waiting time of ≥18 months (range, 0–60) justifies the practice. Program concerns related to use of DHCV NAT+ kidneys include insurance coverage concerns (72%), cost (60%), and perceived risk of transmitting resistant infection (44%).

Conclusions
Addressing knowledge about safety and logistic/financial barriers related to use of DHCV NAT+ kidney transplantation for recipients who are not infected with HCV may help reduce discards and expand the organ supply.

Published: September 2020

Nosso objetivo é compreender o processo criativo de aprendizagem matemática ao longo da produção do jogo Navegação, associado a dispositivo robótico, destinado ao tratamento de sintomas doença de Parkinson. Norteados pela pesquisa qualitativa, a produção de dados foi realizada com alunos do Ensino Médio do IF-XXX, XXXX. O cenário formativo de pesquisa foi criado como lugar para construir/propor soluções para problemas reais a partir da matemática e da robótica a favor da sociedade, de modo que as carreiras científicas e tecnológicas sejam um dos possíveis projetos de vida e transformação social, intelectual e científica dos alunos. Para isso, colocamos em pauta discussão-análises do desenvolvimento científico-tecnológico, colaborativo-argumentativo e inventivo-criativo de tecnologias, indo além dos muros da sala de aula de matemática. Suscitamos análise-reflexões sobre o processo de se tornar pensador criativo em matemática em detrimento da reprodução de conceitos e mecanismos pedagógicos que não se justificam. Para tanto, baseamos nossas ações na Teoria de Aprendizagem Criativa e na Insubordinação Criativa. Concluímos que o processo criativo de aprendizagem matemática se mostra dinâmico e fluído, constituído por passos não lineares, e se fortalece por elementos inerentes ao processo formativo, entre os quais se destacam: curiosidade, imaginação, argumentação e invenção.
Follow-up Studies of Five Cataclysmic Variable Candidates Discovered by LAMOST
Authors: Thorstensen John R. 
Published: September 2020

Abstract
We report follow-up observations of five cataclysmic variable candidates from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) published by Hou et al. LAMOST J024048.51+195226.9 is the most unusual of the five; an early-M type secondary star contributes strongly to its spectrum, and its spectral and photometric behavior are strikingly reminiscent of the hitherto-unique propeller system AE Aqr. We confirm that a 7.34 hr period discovered in the Catalina survey data is orbital. Another object, LAMOST J204305.95+341340.6, appears to be a near twin of the novalike variable V795 Her, with an orbital period in the so-called 2–3 hr “gap.” LAMOST J035913.61+405035.0 is evidently an eclipsing, weakly outbursting dwarf nova with a 5.48 hr period. Our spectrum of LAMOST J090150.09+375444.3 is dominated by a late-type secondary and shows weak, narrow Balmer emission moving in phase with the absorption lines, but at lower amplitude; we do not see the He ii
λ4686 emission evident in the published discovery spectrum. We again confirm that a period from the Catalina data, in this case 6.80 hr, is orbital. LAMOST J033940.98+414805.7 yields a radial-velocity period of 3.54 hr, and its spectrum appears to be typical of novalike variables in this period range. The spectroscopically selected sample from LAMOST evidently includes some interesting cataclysmic variables that have been unrecognized until now, apparently because of the relatively modest range of their photometric variations.
Exploring the Energy Sources Powering the Light Curve of the Type Ibn Supernova PS15dpn and the Mass-loss History of the SN Progenitor
Authors: Wang Shan-Qin , Li Long 
Published: September 2020

Abstract
PS15dpn is a luminous rapidly rising Type Ibn supernova (SN) discovered by Pan-STARRS1. Previous study has showed that its bolometric light curve (LC) cannot be explained by the 56Ni model. In this paper, we used the 56Ni model, the magnetar model, the circumstellar interaction (CSI) model, and the CSI plus 56Ni model to fit the bolometric LC of PS15dpn. We found that the 56Ni model can fit the bolometric LC but the parameters are unrealistic, and that the magnetar model, the CSI model, and the CSI plus 56Ni model can match the data with reasonable parameters. Considering the fact that the emission lines indicative of the interaction between the ejecta and the circumstellar medium (CSM) have been confirmed, and that the SNe produced by the explosions of massive stars can synthesize moderate amounts of 56Ni, we suggest that the CSI plus 56Ni model is the most promising model. Assuming that the CSM is a shell (wind), the masses of the ejecta, the CSM, and the 56Ni are

(

M
⊙),

M
⊙ (

M
⊙), and

M
⊙ (

M
⊙), respectively. The inferred ejecta masses are consistent with the scenario that the progenitors of SNe Ibn are massive Wolf–Rayet stars. Adopting the shell CSM scenario, the shell might be expelled by an eruption of the progenitor just ∼17–167 days prior to the SN explosion; for the wind scenario, the inferred mass-loss rate of the wind is ∼8.0 M
⊙ yr−1, indicating that the wind is a “super-wind” having an extremely high mass-loss rate.
Artificial Intelligence–Assisted Inversion (AIAI) of Synthetic Type Ia Supernova Spectra
Authors: Chen Xingzhuo , Hu Lei , Wang Lifan 
Published: September 2020

Abstract
We generate ∼100,000 model spectra of Type 1a supernovae (SNe Ia) to form a spectral library for the purpose of building an artificial intelligence–assisted inversion (AIAI) algorithm for theoretical models. As a first attempt, we restrict our studies to the time around B-band maximum and compute theoretical spectra with a broad spectral wavelength coverage from 2000 to 10000 Å using the code TARDIS. Based on the library of theoretically calculated spectra, we construct the AIAI algorithm with a multiresidual convolutional neural network to retrieve the contributions of different ionic species to the heavily blended spectral profiles of the theoretical spectra. The AIAI is found to be very powerful in distinguishing spectral patterns due to coupled atomic transitions and has the capacity to quantitatively measure the contributions from different ionic species. By applying the AIAI algorithm to a set of well-observed SN Ia spectra, we demonstrate that the model can yield powerful constraints on the chemical structures of these SNe Ia. Using the chemical structures deduced from AIAI, we successfully reconstructed the observed data, thus confirming the validity of the method. We show that the light-curve decline rate of SNe Ia is correlated with the amount of 56Ni above the photosphere in the ejecta. We detect a clear decrease of 56Ni mass with time that can be attributed to its radioactive decay. Our code and model spectra are available on the website https://github.com/GeronimoChen/AIAI-Supernova.
Gestes d’aide à l’étude en école élémentaire : comparaison entre des classes scolarisant des élèves désignés en situation de handicap et des classes scolarisant des élèves désignés avec des difficultés
Authors: Feuilladieu Sylviane , Dunand Charline 
Published: September 2020

L’enquête présentée porte sur l’observation directe de gestes pédagogiques d’aide à la compréhension des consignes et à la réalisation des exercices, répertoriés au cours de 192 séances de travail (96 en français et 96 en mathématiques, dans 18 classes d’école élémentaire). 15 314 gestes ont ainsi été comptabilisés et comparés selon le type de classe (scolarisant des élèves désignés « en situation de handicap » vs scolarisant des élèves désignés « rencontrant des difficultés importantes ») et selon le type d’élève auxquels ils s’adressent (l’élève désigné vs un autre élève vs le groupe classe). Il s’agit de considérer dans une visée heuristique la pertinence de la notion de degré de généricité-spécificité, qui permet de penser les gestes pédagogiques d’aide non pas de manière décrochée des pratiques ordinaires, mais dans la continuité et l’articulation avec celles-ci, comme orchestration spécifique de dispositions génériques.
L’expérience d’élèves non engagés dans les tâches proposées en EPS : études de cas en volley-ball
Authors: Magendie Élisabeth 
Published: September 2020

L’étude présentée dans cet article est conduite à partir d’analyses approfondies de cas singuliers. Elle s’attache à comprendre l’expérience de trois élèves qui ne sont pas engagés dans les tâches proposées en EPS, afin d’élucider ce qui fait obstacle à leur engagement et les empêche de s’installer dans une posture d’élève apprenant. Elle se réfère à la clinique de l’activité et à l’approche socio-anthropologique du rapport au savoir pour appréhender l’expérience des élèves à deux niveaux : celui de l’activité en cours ; et celui plus global de l’arrière-plan de l’activité en cours. Les analyses ont permis de dresser trois portraits d’expérience vécue en volley-ball. Ces différents portraits rendent compte de processus généraux qui les dépassent. Nous discutons ce qu’ils apportent à la compréhension : des obstacles à l’engagement des élèves ; et du rôle que peuvent jouer les enseignants pour aider les élèves à les surmonter.
Les kayzan au quartier : milieu partisan et trajectoires de distinction dans les quartiers populaires du Grand Khartoum
Authors: Revilla Lucie 
Published: September 2020

L’analyse de l’ancrage social du National Congress Party (NCP) dans les quartiers populaires du Grand Khartoum permet de saisir les registres d’affiliation partisane et les modes organisationnels pris par le mouvement islamiste au Soudan. J’explore les formes de présentation de soi induites par un engagement au NCP, ainsi que les logiques sociales qu’engendre la présence du parti à l’échelle du quartier. La promotion des militant·e·s par la valorisation de modèles d’accomplissement moral reste soumise à la discipline partisane et au « travail émotionnel » mis en œuvre au sein des structures locales du parti, qui façonnent autant qu’ils répriment les dispositions des individus.
La régulation du radicalisme de droite : une comparaison franco-allemande
Authors: Laumond Bénédicte 
Published: September 2020

Cet article s'intéresse aux modes de régulation du radicalisme de droite à l'aune des cas français et allemand. L'analyse se confronte au dilemme de la tolérance rencontré par les démocraties libérales et fondé sur le choix entre autoriser des forces hostiles à la démocratie et courir le risque d'être fragilisé par celles-ci, ou les réprimer et empêcher des citoyens d'exercer leurs libertés fondamentales. Nous croisons les résultats d'une campagne d'entretiens menée entre 2014 et 2017 auprès des acteurs répondant au radicalisme de droite en Allemagne et en France et la littérature sur la démocratie militante. L'examen des représentations qu'ont les acteurs publics du radicalisme de droite permet d'identifier des rapports différenciés au politique. Nous observons dans les deux cas que les acteurs étatiques entreprennent des processus de catégorisation du politique qui contribuent à ériger les frontières de l'ordre politique démocratique. Mais deux modèles de régulation se dessinent : l'Allemagne se rapproche du modèle social de défense démocratique, tandis que la France oscille entre politisation et dépolitisation de la lutte contre le radicalisme de droite.
COVID – 19 Impact: Domestic violence and the BAME community
Authors: Sapkota Bindu Devkota 
Published: September 2020

The Coronavirus disease which started in Wuhan, China, was declared a pandemic on 11th March 2020. Since then the world has come together for the trial and approval of vaccination. Meanwhile, the adopted approach to prevent and slow down the coronavirus is social distancing, handwashing, and use of face masks. In the UK, the government, together with the National Health Service (NHS), have taken various approaches to prevent and slow down the spread of coronavirus. These included imposing a ‘lockdown’ of the country (e.g. closure of schools, businesses, parks, leisure centres), along with the emphasis on handwashing, social distancing, the use of face masks and only permitting essential travel within the UK and between the UK and other countries. These approaches have been undertaken to varying extents and within different timeframes across the four nations of the UK. Like many other countries worldwide, the UK was not prepared for such pandemics which resulted in the inability to assess the most appropriate approach to contain the spread, including the availability of Personal Protective Equipment (PPE) for frontline workers, particularly those in health care. As the crisis continues several striking social issues have emerged which may, in part, be a consequence of the measures taken. These include the escalation in domestic violence (DV) and disproportionate burden of disease among the Black, Asian, and Minority Ethnic (BAME) community. The impact of Covid-19 may remain for a long time if appropriate measures are not put in place to address the health inequalities in time.
