L’apprentissage par cœur, au-delà de la polémique
Authors: Abernot Yvan , Audran Jacques , Penso Éric 
Published: September 2021

Au regard des dernières orientations gouvernementales, l’apprentissage par cœur connaît un regain d’intérêt, ce qui ne va pas sans controverses. Cette étude propose une approche réflexive, mais aussi d’investigation, qui tend à soutenir l’hypothèse d’une complémentarité de l’apprentissage « par cœur » et de la compréhension. Après avoir défini le concept, nous tentons de classer les objets et les fonctions de l’apprentissage dit par cœur pour en dégager les bénéfices et les risques. Pour étayer cette problématique, nous avons analysé les réponses de trente quatre enseignants du primaire qui se positionnent et enrichissent la réflexion. Il semble qu’au-delà des représentations parfois dogmatiques, voire idéologiques, des spécialistes et des partenaires de l’éducation, l’apprentissage par cœur puisse s’inscrire dans un projet assez ambitieux à condition de ne pas se réduire au psittacisme ou aux facilités d’évaluation.

Published: September 2021

Introduction:
To reduce contacts during the COVID-19 pandemic, we elaborated a protocol for ambulatory referrals for exercise testing that included discharges from the stress test laboratory (STL).

Methods and Results:
From 403 patients referred for chest pain (68%) or dyspnea (32%), 219 were straight discharged from the STL (54%), without findings of coronary artery disease in 192 (88%), whereas in 120 (29.5%), further visits were recommended. Medical treatment was modified after the tests in 116 patients (29%).

Conclusions:
A strategy consisting of discharge from the STL for patients with negative/spurious stress test results, making therapeutic recommendations, seems feasible, effective, and overall opportune in the current situation.

Published: September 2021

Background:
Female genital tuberculosis (FGTB) is a common problem in developing countries causing significant morbidity, especially infertility. Radiological imaging, especially ultrasound, can help in diagnosis of FGTB with tubo-ovarian masses.

Aims:
The present study was performed to evaluate the role of ultrasound in diagnosis of FGTB and to see various findings of FGTB on ultrasound.

Study Setting and Design:
It was a prospective cross-sectional study over 4-year period between August 2015 and August 2019 in a tertiary referral center.

Subjects and Methods:
One hundred and seventy-five patients of infertility diagnosed to have FGTB on composite reference standard (CRS) of positive acid-fast bacilli on microscopy or culture of endometrial biopsy, positive polymerase chain reaction, positive GeneXpert, epithelioid granuloma on histology of endometrial biopsy, or definite or probable finding of FGTB on laparoscopy were subjected to transvaginal ultrasound by an experienced sonographer for various findings of FGTB.

Statistical Analysis:
Data analysis was carried out using STATA software 12.0. Comparison of categorical values was tested using Chi-square Fisher's exact test, with P < 0.05 being taken as significant.

Results:
Mean age, body mass index, parity, and duration of infertility were 28.9 years, 22.9 kg/m2, 0.26, and 6.06 years, respectively. Menstrual dysfunction was common (44%). Diagnosis of FGTB was made by CRS. Ultrasound was normal in 112 (64%) cases and was abnormal in 63 (36%) cases. Various ultrasound findings were ovarian cyst (23.42%), tubo-ovarian masses (15.42%), unilateral or bilateral hydrosalpinx (13.71%), pyosalpinx (0.57%), adhesion (1.14%), adnexal fixity (6.28%), thin endometrium (24.57%), endometrial fluid (12.57%), endometrial calcification (1.7%), endometrial synechiae (4.57%), cornual synechiae (2.28%), impaired endometrial vascularity (21.71%), ascites (6.85%), and peritoneal or omental thickening (1.75%).

Conclusion:
Carefully performed ultrasound is a useful modality in diagnosis of FGTB, especially in adnexal masses.
Evaluating the Contribution of Oocyte, Sperm, and Uterus in Determining the Outcome of Intracytoplasmic Sperm Injection – A Retrospective Observational Comparative Study on Intracytoplasmic Sperm Injection using Own Oocytes and Donor Oocytes
Authors: Shanthi Deepeka Thangamani , Gopinath Parasuram , Kumar Karthika D. , Iyer Ramesh Parameswara , Kesavaramanujam Revathi , Karunakaran Gopinathan Kannoly 
Published: September 2021

Context:
Several studies have assessed the contribution of oocyte, sperm, and endometrium on the outcome of intracytoplasmic sperm injection (ICSI) separately. This study assesses the relative contribution of oocyte, sperm, and uterus in achieving clinical pregnancy (CP) through ICSI by comparing own and third-party ICSI cycles.

Aim:
The aim of the study is to evaluate and compare the strength of contribution of oocyte, sperm, and uterus in achieving CP through ICSI.

Settings and Design:
This retrospective observational study of ICSI cycles for 20 months including 1000 embryo transfers (ETs).

Methodology:
Subjects were divided into two groups, Group 1 – ICSI with own oocytes (550 ETs) and Group 2 – ICSI with donor oocytes (450 ETs). Both the groups had 3 subgroups – a (husband sperm, transferred to self), b (donor sperm, transferred to self), c (husband sperm, transferred to a gestational surrogate). CP rate (CPR) as a major outcome was studied in the groups and subgroups.

Statistical Analysis:
CPR was compared between various subgroups using Z-test and Chi-square of significance of difference between proportions. A P < 0.05 was taken as the level of statistical significance.

Results:
CPR in subgroup 1a < 35 years, 1a ≥35 years, and 2a was 42.98%, 26.21%, and 40.92%, respectively (P = 0.001). CPR was compared between 2a and 2c (40.92%, 56.5%, P = 0.044) and between 2a and 2b (40.92%, 42.11%, P = 0.866). Implantation rate was highest in Group 2c (34.88%) compared to other subgroups.

Conclusion:
The higher CPR in women <35 years undergoing ICSI with own oocytes than older women and a comparable CPR as that of recipients of donor oocytes suggests that age thereby oocyte quality is the strongest determining factor in achieving clinical pregnancy. Among oocyte recipients, higher CPR in surrogate uterus than patient uterus suggests that uterus/endometrium plays a considerable role, and comparable CPR between ICSI using husband sperm and donor sperm indicates that sperm quality might not play a major role in achieving CP.

Authors: Karthikeyan Madhuvanti , N.S. Kubera , Singh Rakesh 
Published: September 2021

Context:
Infections are an important cause of male infertility. The specific effects of infections on various semen parameters remain unexplored, especially within the Indian subcontinent.

Aim:
The aim of the study was to determine the bacteriologic profile of semen, and its effect on semen parameters, with particular emphasis given to Ureaplasma urealyticum and Mycoplasma hominis tested by semen polymerase chain reaction (PCR).

Study Setting and Design:
The research was a cross-sectionl analaytical study conducted in a tertiary care center in South India from March 2018 to November 2019, on 48 male partners of couples presenting with infertility.

Methodology:
After obtaining informed consent from the study participants, semen collection was done. The sample was subjected to standard semen analysis according to the WHO 2010 Manual, followed by bacteriological testing using routine culture methods. In addition, real-time PCR was done to test for U. urealyticum and M. hominis.

Statistical Analysis:
Demographic data, semen analysis parameters, bacteriological culture findings, and real-time PCR results were compared and analyzed using the software IBM® SPSS 19.0.

Results:
A significant difference in viscosity of semen, which was higher in the samples that were positive for real-time PCR of M. hominis, was found. Other than this, no other parameter had a statistically significant difference between culture or real-time PCR positive samples and negative samples.

Conclusion:
Our study, though limited by a small sample size, highlights the role played by seminal infections in the context of male infertility. Larger scale prospective studies in this area would be invaluable in deciding the management plans of male factor infertility.
An Artificial Intelligence-Based Algorithm for Predicting Pregnancy Success Using Static Images Captured by Optical Light Microscopy during Intracytoplasmic Sperm Injection
Authors: Geller Jared , Collazo Ineabelle , Pai Raghav , Hendon Nicholas , Lokeshwar Soum D. , Arora Himanshu , Molina Manuel , Ramasamy Ranjith 
Published: September 2021

Context (Background):
Analysis of embryos for in vitro fertilization (IVF) involves manual grading of human embryos through light microscopy. Recent research shows that artificial intelligence techniques applied to time lapse embryo images can successfully ascertain embryo quality. However, laboratories often capture static images and cannot apply this research in a real-world setting. Further, current models do not predict the outcome of pregnancy.

Aims:
To create and assess a convolutional neural network to predict embryo quality using static images from a limited dataset. We considered two classification problems: predicting whether an embryo will lead to a pregnancy or not and predicting the outcome of that pregnancy.

Settings and Design:
We utilized transfer learning techniques using a pretrained Inception V1 network. All models were built using the Tensorflow software package.

Methods:
We utilized a total of 361 randomly sampled static images collected from four South Florida IVF clinics. Data were collected between 2016 and 2019.

Statistical Analysis Used:
We utilized deep-learning techniques, including data augmentation to reduce model variance and transfer learning to bolster our limited dataset. We used a standard train/validation/ test dataset split to avoid model overfitting.

Results:
Our algorithm achieved 0.657 area under the curve for predicting pregnancy versus nonpregnancy. However, our model was unable to meaningfully predict whether a pregnancy led a to live birth.

Conclusions:
Despite the limited dataset that achieved somewhat of a lower accuracy than conventional embryo selection, this is the first study that has successfully made IVF predictions from static images alone. Future availability of more data may allow for prospective validation and further generalisability of results.
Translanguaging: A tool to decolonise students’ experiences of learning to write for academic purposes in the South African university context
Authors: Ngcobo Sandiso , Bryant Katie , Ndebele Hloniphani 
Published: September 2021

University students can experience many challenges writing for academic purposes as they move from secondary to post-secondary studies. Both first and additional language users of English experience these challenges, resulting in universities across the globe instituting different modalities to help ease students’ transitions. In South African universities, despite English being the medium of instruction, most students are additional language speakers of English. This article discusses findings from a 2019 study that investigated three questions: 1) Do firstyear, additional language users of English choose to engage in translanguaging when presented with such an opportunity in their university courses? 2) If they choose to use this tool, how do they employ the genre conventions and discourse markers of the traditional academic essay? 3) What are their reactions to being presented with the opportunity to use translanguaging in their academic studies? The findings illustrate that approximately half of the study’s participants chose to employ translanguaging in their responses and were able to successfully use the genre conventions and discourse makers of the academic essay.
CRITICAL SUCCESS FACTORS FOR ADOPTION OF CLOUD COMPUTING IN PUBLIC UNIVERSITIES IN KENYA
Authors: Too Charles , Bomett Emily , Kiprop Catherine 
Published: September 2021

<p>Cloud computing technology is a distributed computing approach whereby users access shared resources under various service models through the internet. It allows individual access to information technology resources through the internet upon demand. Cloud computing is an essentially growing terminology in the IT world and has become increasingly present in the life of institutions of higher learning. Institutions of higher learning consider cloud computing and construction of digital content platforms as a way of enhancing resource utilization and improvement of service delivery. The sudden and frenzied rush for cloud computing by universities has been aggravated by exponential growth in data traffic and the need for innovative learning such as e-learning and virtual classrooms amid COVID 19 pandemic (Kenya Education Network-KENET, 2021). Perhaps it is from that realization and the need to adhere to COVID 19 protocols that most public universities in Kenya have adopted cloud computing. In this study, we sought to find out the critical success factors for adoption of cloud computing in public universities in Kenya. The study set out three (3) objectives and consequently three (3) null hypotheses to guide it. Quantitative research design was adopted for this study. Similarly, International Business Machines-IBM (2011) model for cloud adoption offered theoretical guidance. At a confidence interval of 95%, an online sample size calculator was used to arrive at three hundred and sixty two (362) respondents out of six thousand two hundred (6200) target population. Proportionate stratified random sampling technique and an online list randomizer were used to select respondents in the selected universities to participate in the study. Multiple regression was used to test the hypotheses in this study based on empirical data obtained by a survey questionnaire of thirty nine (39) questions from the two (2) public universities. Multiple regression results showed significant positive effect of Management Support (β=.257), Technical Support (β=.353), and User Preparedness (β=.475) on adoption of cloud computing at p&lt;.05. Regression results gave a coefficient of determination R2=.908 which means 90.8% of the variation in adoption of cloud computing can be explained by Management Support, Technical Support, and User Preparedness combined. Based on the coefficient of determination (R2), the three null hypotheses (H01, H02, &amp; H03) were rejected at p&lt;0.05. Regression analysis showed that Management Support, Technical Support and User Preparedness are critical success factors in cloud adoption in public universities in Kenya. This study provides new and relevant insights to literature on cloud adoption in higher education service in Kenya.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0984/a.php" alt="Hit counter" /></p>

El estilo de comunicación del entrenador como predictor de la carga de trabajo percibida en jóvenes futbolistas (Coach communication style as a predictor of perceived workload in young football players)
Authors: Silva Flores Roberto , Mas Riera Jaume , Garcia-Mas Alexandre 
Published: September 2021

El objetivo del presente trabajo fue conocer las implicaciones del estilo comunicativo del entrenador durante la realización de la actividad en la carga de trabajo percibida por jugadores jóvenes de fútbol. En el estudio participaron dos equipos de la categoría cadete, siendo un total de 32 jugadores (M = 15.19; SD = 0.39), y sus dos respectivos entrenadores. La recogida de datos tuvo lugar en dos entrenamientos diferentes, con un intervalo de una semana entre cada actividad. La carga de trabajo se midió mediante el NASA-TLX adaptado a la herramienta de Google Forms que los jugadores contestaron después de la actividad. Para analizar la comunicación del entrenador se utilizó la grabación en video y audio de la actividad para un posterior análisis a través de una adaptación del CBAS. Aunque los entrenadores presentan dos estilos comunicativos distintos, los resultados no muestran una diferencia significativa entre los dos equipos en la carga de trabajo percibida. Sin embargo, el estilo comunicativo directivo presenta una tendencia a una mayor exigencia mental, una mayor frustración y un menor rendimiento percibido.
Abstract. The aim of this study was to know the implications of the coach's communicative style during the performance of the activity on the workload perceived by young soccer players. Two teams from the cadet category participated in the study, with a total of 32 players (M = 15.19; SD = 0.39), and their two respective coaches. Data collection took place in two different workouts, with an interval of one week between each activity. The workload was measured using the NASA-TLX adapted to the Google Forms tool that the players answered after the activity. Regarding the analysis of the coach's communication, video and audio recording of the activity was used for subsequent analysis through an adaptation of CBAS. Although the coaches have two different communication styles, the results don’t show a significant difference between the two teams in perceived workload. However, the managerial communication style presents a trend towards greater mental demand, greater frustration and lower performance perceived.
