Évaluation du niveau de maîtrise des connaissances professionnelles TPACK d’enseignants du secondaire intégrant la simulation comme instrument pédagogique dans un cours : Étude de cas au Cameroun.
Authors: Dabove-Foueko Georges Modeste , Becerril Ortega Raquel 
Published: May 2021

Cette contribution propose une classification des statuts de maîtrise des connaissances professionnelles activées dans l’enseignement d’un cours à l’aide de la simulation informatique. L’évaluation des domaines de connaissances réalisée s’appuie sur la catégorisation du TPACK[1] de (Mishra et Koehler, 2006) et implique 40 enseignants des lycées au Cameroun. L’analyse des données recueillies à l’aide d’un questionnaire Likert a révélé une configuration épistémologique constituée de trois statuts dominants de maîtrise des connaissances professionnelles parmi les enseignants. La classe n°1 réfère au statut de maîtrise composée majoritairement d’enseignants possédant un niveau « insuffisant ». Elle renferme les connaissances des contenus (CK), technologiques liées aux contenus (TCK) et technopédagogiques du contenu (TPCK). La classe n°2 renvoie au statut de maîtrise pour lequel la plupart des enseignants expriment un niveau « satisfaisant ». Elle adresse les connaissances pédagogiques liées aux contenus (PCK). Enfin, la classe n°3 correspond au statut de maîtrise pour lequel les enseignants se positionnent majoritairement au niveau « d’expert ». Celle-ci inclut les connaissances pédagogiques (PK), technologiques (TK) et technopédagogique (TPK). Ces résultats ouvrent la perspective d’une réflexion sur les actions à entreprendre pour développer la professionnalité des enseignants par le biais de la formation.

Boundary Crossing between Formal and Informal Learning Opportunities: A Pathway for Advancing e-Learning Sustainability
Authors: Bradshaw Kathlyn , Lock Jennifer , Parchoma Gale 
Published: May 2021

In this article, third generation cultural historical activity theory (CHAT) (Engeström, 2011) will be the means for analyzing tensions and contradictions between formal and informal learning within a MOOC design. This article builds on previous work (Bradshaw, Parchoma & Lock, 2017) wherein cultural historical activity theory (CHAT) was used to establish formal and informal learning as activity systems. Formal and informal learning are considered in relation to designing learning for a MOOC environment. Findings from an in situ study specifically examining CHAT elements in the process of design are considered in a movement towards making visible what those tasked with designing courses normally do not see in relation to informal learning. Implications for practice are presented in a CHAT-Informed MOOC design model intended to augment typical approaches to instructional design. The outcome is an argument for CHAT-Informed MOOC design model can intentionally address both formal and informal opportunities for learning.
Feasibility of Virtual Reality Audiological Testing: Prospective Study
Authors: Seol Hye Yoon , Kang Soojin , Lim Jihyun , Hong Sung Hwa , Moon Il Joon 
Published: May 2021

BackgroundIt has been noted in the literature that there is a gap between clinical assessment and real-world performance. Real-world conversations entail visual and audio information, yet there are not any audiological assessment tools that include visual information. Virtual reality (VR) technology has been applied to various areas, including audiology. However, the use of VR in speech-in-noise perception has not yet been investigated.ObjectiveThe purpose of this study was to investigate the impact of virtual space (VS) on speech performance and its feasibility to be used as a speech test instrument. We hypothesized that individuals’ ability to recognize speech would improve when visual cues were provided.MethodsA total of 30 individuals with normal hearing and 25 individuals with hearing loss completed pure-tone audiometry and the Korean version of the Hearing in Noise Test (K-HINT) under three conditions—conventional K-HINT (cK-HINT), VS on PC (VSPC), and VS head-mounted display (VSHMD)—at –10 dB, –5 dB, 0 dB, and +5 dB signal-to-noise ratios (SNRs). Participants listened to target speech and repeated it back to the tester for all conditions. Hearing aid users in the hearing loss group completed testing under unaided and aided conditions. A questionnaire was administered after testing to gather subjective opinions on the headset, the VSHMD condition, and test preference.ResultsProvision of visual information had a significant impact on speech performance between the normal hearing and hearing impaired groups. The Mann-Whitney U test showed statistical significance (P<.05) between the two groups under all test conditions. Hearing aid use led to better integration of audio and visual cues. Statistical significance through the Mann-Whitney U test was observed for –5 dB (P=.04) and 0 dB (P=.02) SNRs under the cK-HINT condition, as well as for –10 dB (P=.007) and 0 dB (P=.04) SNRs under the VSPC condition, between hearing aid and non–hearing aid users. Participants reported positive responses across almost all items on the questionnaire except for the weight of the headset. Participants preferred a test method with visual imagery, but found the headset to be heavy.ConclusionsFindings are in line with previous literature that showed that visual cues were beneficial for communication. This is the first study to include hearing aid users with a more naturalistic stimulus and a relatively simple test environment, suggesting the feasibility of VR audiological testing in clinical practice.

Background and objectives
The relationship of depressive symptoms with kidney function remains poorly investigated. We aimed to evaluate the prospective association between depressive symptoms and rapid decline in kidney function in Chinese adults with normal kidney function.

Design, setting, participants, & measurements
A total of 4763 participants with eGFR≥60 ml/min per 1.73 m2 at baseline were enrolled from the China Health and Retirement Longitudinal Study. Baseline depressive symptoms were determined using a ten-item Center for Epidemiologic Studies Depression scale with a cutoff score of greater than or equal to ten to define high depressive symptoms. The GFR was estimated by a combination of serum creatinine and cystatin C. The primary outcome was rapid decline in kidney function, defined as an annualized decline in eGFR of ≥5 ml/min per 1.73 m2. Secondary outcome was defined as an annualized decline in eGFR of ≥5 ml/min per 1.73 m2 and to a level of <60 ml/min per 1.73 m2 at the exit visit.

Results
During a median follow-up of 4 years (interquartile range, 3.92–4.00), 260 (6%) participants developed rapid decline in kidney function. Overall, there was a significant positive association between baseline depressive symptoms and rapid decline in kidney function (per five-scores increment; adjusted odds ratio, 1.15; 95% confidence interval, 1.03 to 1.28) after adjustments for major demographic, clinical, or psychosocial covariates. Consistently, compared with participants with low depressive symptoms (total Center for Epidemiologic Studies Depression scale score less than ten), a significantly higher risk of rapid decline in kidney function was found among those with high depressive symptoms (total Center for Epidemiologic Studies Depression scale score greater than or equal to ten; adjusted odds ratio, 1.39; 95% confidence interval, 1.03 to 1.88). Similar results were found for the secondary outcome (per five-scores increment; adjusted odds ratio, 1.26; 95% confidence interval, 1.06 to 1.51).

Conclusions
High depressive symptoms were significantly associated with a higher risk of rapid kidney function decline among Chinese adults with normal kidney function.
Reflection of Indian Culture in Shashi Deshpande’s A Matter of Time
Authors: Jena Prajesh 
Published: May 2021

Shashi Deshpande is a well-known name in the field of Indian literature and is a contemporary writer from Karnataka. She portrays in her novel "A Matter of Time" the truth of Indian society in Indian families. The importance of culture for Indian women is also discussed. Her novels are distinguished for their genuine depictions of the Indians and their history. She used Indian names and the role of Indian Middle Class Women in her novel A Matter of Time through the character Sumi. She talks about Indian Women, Indian Culture, Indian Religion, Indian Family, Religions and Beliefs, Family Traditions, and Emotions, among other topics. A Matter of Time is a multi-generational novel that moves around the plight and predicament of Indian women whose lives are deeply rooted in Indian beliefs, superstitions, conventions and traditions.
Women have been living and breathing silently for thousands of years under the umbrella of patriarchy and with their "gazing." With the foundation of patriarchy, the disparity between man and woman, in its unwritten form, has developed through language, customs, rituals, myths and practises. Myths, rituals, and customs contribute to the evolution and establishment of human society. They are naturally developed, but are indeed societal buildings and help in developing patriarchal ideologies. They are believed to be natural. They are, therefore, essential to women's subjugation in our society.

Published: May 2021

Abstract
Satellite-Derived Bathymetry (SDB) modeling is used to derive bathymetric data needed for enriching several applications including nautical charting. The nautical charts of Safaga port, Egypt, contains significant gaps as they are based on 50-years old hydrographic survey data and it needs an update. We applied the SDB algorithm (log-ratio approach) using multispectral Landsat-8 OLI images for extracting bathymetry to update the nautical charts of SAFAGA port. The results are verified against the old nautical chart of SAFAGA with a coefficient of determination (R2) varies between 0.42 to 0.71 in areas where hydrographic data are old, unavailable or costly to obtain.
A Simple PSO-Based Method for Power Distribution System Components Reliability Parameters Calibration
Authors: Shojaeian Shahrokh , Rizi Sajjad Hashemi 
Published: May 2021

Abstract
In this paper, a proposed algorithm based on Particle Swarm Optimization (PSO) is used to present a simple method for data calibration of reliability indices in electrical power distribution networks. The main feature of the proposed method is its comprehensiveness, since the whole reliability indices can be calibrated using a proper objective function. In order to evaluate the effectiveness of the suggested algorithm, calculations are made on the well-known IEEE-RBTS Bus2 test system. The results confirm the simplicity and validation of the proposed method, and verify that by applying the proposed method, the computation speed for data calibration can be reduced as well.

Published: May 2021

Abstract
The emergence of SARS-CoV-2 affected care both for acute and chronic health conditions. Majority of the patients with cardiac implantable electronic devices (CIEDs) have multiple comorbidities, which can influence their response to COVID-19. An online survey consisting of 45 multiple-choice question was designed for CIED patients assessing comorbidities and overall health condition during September -December 2020. A multivariate analysis based on principal axis factoring (PAF) was performed on the eligible 184 survey response. Three factors were identified. Ten-year survival rates were calculated with Charlson Comorbidity Index. The extracted factors explained 66.1% of the cumulative variance and were consistent with medical literature data.

Authors: Amamou Salem , Vandercleyen François , Desbiens Jean-François 
Published: May 2021

Abstract
Pre-service training is a critical period for establishing the beliefs of future teachers in their ability to successfully assume their responsibilities as teachers. One of the goals of teacher education programs would therefore be to cultivate a high sense of competence among students.
For this purpose, a scale to measure the perception of self-efficacy (PSE) among Quebec physical and health education trainees during teaching has been developed and empirically validated. Teacher trainees (n = 232) enrolled in 3rd and 4th year in the Bachelor of Education in Physical and Health Education (PHE) in four different university programs in Quebec participated in the study.
Subsequent exploratory and quasi-confirmatory factor analyses led to the development of an instrument with 19 items divided into three factors, explaining 66.10 % of the total variance. The convergent and divergent measures of validity are satisfactory, as are those of the reliability of the three scales (upper lower limit: .78 to .93). Finally, the RMSR, CFI, RMSEA and NNFI indices show an excellent goodness of fit of the model obtained.
A Descriptive Analysis of the Leadership Practices of Primary School Principals in Promoting Sustainability Through Motivating Teachers
Authors: Khumalo Shuti Steph 
Published: May 2021

Abstract
Enhancing sustainability in primary schools is apposite because primary schools are the building blocks in any education system. In its examination, the study provides insights on the role of primary school principals in promoting sustainable education through inspiring teachers. Teacher motivation is a very critical focus research area, particularly in the present depressing times and particularly in promoting sustainability. Without ignoring and dismissing other factors that have a bearing on the poor performance of the South African primary schools, teacher discouragement is one of the factors. The purpose of this investigation was to explore the extent in which the leadership practices of primary school principals promote teacher motivation and ultimately achieving sustainable teacher workforce. This study was based on random sampled primary school teachers in South Africa, Waterberg District. Hundred and fifty survey questionnaires were distributed to participating primary schools and only 96 responses were received. The respondents were from a mix of both male and female teachers who responded to the questionnaire. Descriptive statistics was applied to analyse data. Even though the results indicated that there were issues with teacher motivation, to a significant extent, the majority of respondents demonstrated that most primary principals do take efforts in trying to ensure that teachers are motivated. The results of the study deepen the already existing scope of knowledge regarding teacher motivation, particularly in primary schools.
Identifying Assessment Opportunities in Postgraduate Learning for Sustainability
Authors: Gajparia Jaya , Strachan Glenn , Vare Paul , Ferguson Therese 
Published: May 2021

Abstract
This paper offers a rationale for how ESD related learning at postgraduate level can be assessed. It proposes a framework for evaluating whether assessments in Master’s level programmes align with the pedagogical approach of Education for Sustainable Development (ESD). If assessment is to contribute to the overall learning process, then the nature of the assessment should reflect the pedagogy, values and principles associated with ESD. Utilising an Appreciative Inquiry model, existing models of competences for sustainable development have been used to develop the framework. The framework is not aimed at the performance of the students; rather, it is applied to the course itself to identify if assessment opportunities are in keeping with an ESD approach. The framework is applied to three examples from Master’s programmes, with which the authors are affiliated in England and Jamaica. The findings identify key characteristics that should feature in assessing learning for sustainability. The framework enabled the authors to gauge the extent to which their assessment regimes are in line with the aims, purpose and content of their programmes. While the examples cited are from the field of education, the framework can be applied to any Master’s programmes containing elements of sustainable development.
High-throughput sequencing in vaccine research
Authors: Pasik Katarzyna , Domańska-Blicharz Katarzyna 
Published: May 2021

Abstract
The world of vaccines has changed tremendously since the time of Louis Pasteur. In the present day, it is regarded as vaccinology, a discipline which includes not only the knowledge of vaccine production, strategies for its delivery and influence on the clinical course of disease and the response of the host immune system but also regulatory, ethical, economic and ecological aspects of their use. A hundred years after Pasteur created the first vaccine, there was another scientific breakthrough of great importance in this field, i. e. Sanger sequencing. Progress in genome sequencing and other molecular techniques over the intervening 40 years has been enormous. High-throughput sequencing (HTS) platforms and bioinformatics tools are becoming widely available, falling in cost, and results are achieved very quickly. They enable the construction of modern vaccines, as well as the assessment of their safety, effectiveness and impact on the host organism and the environment. These techniques can also provide a tool for quality control of vaccines. Unprecedented possibilities are opened up by the HTS technique, but limiting factors on its implementation have to be contended with such as lack of reference materials and problems with method optimisation or validation. In the face of the current COVID-19 pandemic, a significant role is allotted to this sequencing technique while an effective vaccine against the disease caused by SARS-CoV-2 is sough.
Hacking into Cybertherapy: Considering a Gesture-enhanced Therapy with Avatars (g+TA)
Authors: Gerner Alexander Matthias 
Published: May 2021

Abstract
This paper will philosophically extend Julian Leff’s Avatar therapy paradigm (AT) for voice-like hallucinations that was initially proposed for treatment-resistant Schizophrenia patients into the realm of gesture-enhanced embodied cognition and Virtual Reality (VR), entitled g+TA (gesture-enhanced Avatar Therapy). I propose an philosophy of technology approach of embodied rhetorics of triadic kinetic “actions” in the sense of Charles Sanders Peirce that transforms the voice hallucination incorporated by an avatar- and that can confront acousmatic voice-like hallucinations with a method of gesture synchronization and dyssynchronization and gestural refusal of interaction that the player with the Avatar can resist in full embodiment. This paper therefore introduces a gesture-enhanced, extended version of Cybertherapy with Avatars that tackle multimodal bodily experience of voice-like hallucinations beyond mere visual or auditory stimulation. This is put forward theoretically in a 4E-cognition approach that expands Avatar Therapy with gestures into VR.

Authors: Koohestani Arezoo , Fathi Mehrdad , Hejazi Keyvan 
Published: May 2021

Abstract

Introduction. Addiction is a chronic disease that needs time-consuming treatment. The medicines used to stop or reduce the tendency have not been successful so far. The purpose of this study was to investigate the effect of six weeks of aerobic training (morning and afternoon) on some brain neurotransmitters, brain-derived neurotrophic factor and quality of life in addicted females.

Material and Methods. Thirty subjects were selected and divided into intervention (n = 15) and control (n = 15) groups. The aerobic training program consisted of six weeks of aerobic training, 3 sessions per week, and each session lasted for 45 to 60 minutes with a maximum intensity of 50-70% of the maximum heart rate. Paired sample t-test and ANCOVA were used to compare between- and within-group variance changes.

Results. Weight levels, body mass index and body fat percentage significantly decreased (p < 0.05), while the serum levels of serotonin, dopamine and brain-derived neurotrophic factor (BDNF) increased significantly. The maximum oxygen consumption and quality of life increased significantly at the end of the period. Changes in intra-group mean in weight, body mass index, body fat percentage, dopamine, BDNF, maximum oxygen consumption, physical limitation, general health, vitality, social activity, physical and emotional function and life satisfaction are significantly different between experimental and control groups (p < 0.05).

Conclusions. Six-week aerobic training performed in the morning and afternoon reduces body composition indicators and increases brain neurotransmitters, quality of life and maximum oxygen consumption in addicted females. Therefore, it can be effective in improving physical and mental health.
EMG Activity of Transversus Abdominis, Multifidus and Co-Contraction Index in Different Phases Amongst Varied Level Archers: A Cross-Sectional Study
Authors: Azhar Sheikh , Sharma Saurabh , Sharma Shalini , Tanwar Tarushi 
Published: May 2021

Abstract

Introduction. Core muscle activity is a necessary requirement in most sports. However, its role in archers has not been studied. Therefore, this study sought to determine muscle activity of Transversus abdominis (TA) and Multifidus (MF) and co-contraction index (CCI) using surface electromyography (s EMG) during different phases of shots in archers with different levels of training.

Material and Methods. It was an observational study with a cross-sectional design. Twenty-eight healthy male archers were recruited and grouped according to their level of training: Group A (Beginners (n = 9)), Group B (Trained (n = 10)), Group C (Elite (n = 9)). The muscle activation (%MVIC) for MF and TA for 10 successive archery shots (distance: 10 meters in 200 seconds) was recorded using s EMG for all the phases of the shots along with CCI.

Results. Three-way ANOVA revealed a significant difference for TA activity within groups (p ≤ 0.001) and phases (p = 0.002), A significant difference for MF activity was found within groups (p ≤ 0.001). A significant difference for CCI was found between groups (p ≤ 0.001) and in the interaction between phase × shot (p = 0.001).

Conclusions. The findings of the study showed that elite archers had more activity of the core muscles (TA and MF) and their CCI was found to be much higher with respect to the trained and beginner archers. Therefore, it is essential to incorporate dynamic stabilization exercises into archery training.
