La gestion particulière de la classe d’arts plastiques et multimédia au secondaire
Authors: Gagné Maryse , Deslauriers Anne , Lalonde Martin 
Published: April 2023

Dans le cours d’arts plastiques en milieu scolaire règne une énergie perceptible par quiconque passe devant la porte. Poser le pied dans le local d’art consiste à pénétrer dans un univers entraînant, animé et imprévisible qui participe à l’élan créateur des élèves. Fondamentalement interdisciplinaire, l’enseignement des arts plastiques au secondaire poursuit la mission de l’école québécoise en développant la créativité de l’élève et sa capacité à comprendre et apprécier les représentations, les « images », auxquelles elle ou il se confronte dans son expérience du monde. L’atelier d’arts plastiques, tout comme celui de multimédia, se veulent donc, avant toute chose, des lieux de recherche et d’exploration où, pour reprendre une expression qu’ils emploient souvent, les élèves peuvent « être libres », ce qui n’est pas le cas pour tout le cursus. Cette liberté se manifeste dans leurs actions et leurs comportements individuels, collectifs et en relation avec leur environnement. Il ne fait aucun doute qu’en raison de la nature mouvante de cette discipline, les élèves s’y expriment d’une manière tout autre. Par conséquent, une gestion de classe particulière est requise, prenant en compte la nature complexe et imprévisible de chaque situation d’apprentissage.
Mieux connaître ses élèves favorise une bonne gestion de classe
Authors: Loiselle Stéphanie 
Published: April 2023

Le contact avec la jeunesse est sans doute une des principales raisons qui expliquent pourquoi de nombreuses personnes choisissent la voie de l’enseignement. Leur spontanéité, leur curiosité et leur vivacité sont quelques aspects de leur personnalité qui font que les jeunes ont tant à nous apporter. Cependant, lorsque qu’une bonne gestion de classe est ébranlée, le plaisir d’enseigner peut rapidement faire place au stress. Il n’y a pas de recette magique pour assurer une gestion saine et propice à l’apprentissage, il y a néanmoins un principe de base ; le développement de relations sociales positives (Gaudreau, 2011).
Mobiliser la transdisciplinarité comme posture de recherche : le cas de l’analyse des politiques publiques de l’université au Québec
Authors: Bernatchez Jean 
Published: April 2023

Cet article vise à démontrer pourquoi et comment nous mobilisons la transdisciplinarité comme posture de recherche pour le cas de l’analyse des politiques publiques de l’université au Québec. La transdisciplinarité est une posture de recherche riche et féconde, mais qui présente néanmoins plusieurs défis sur le plan de la faisabilité et quant à son accueil dans l’espace scientifique. Nous précisons dans cet article notre posture de recherche, balisée par quatre principes : la transdisciplinarité, la contextualisation, la dialogique et la systémique. Nous présentons l’espace de sens qui permet de contextualiser notre objet de recherche, constitué de deux champs : l’enseignement supérieur et les sciences studies. Nous présentons les quatre pôles (épistémologique, morphologique, théorique et technique) et les choix afférents de la dynamique de notre recherche. Nous illustrons une contribution rendue possible par la mobilisation de la transdisciplinarité dans cet espace de sens que sont les politiques publiques de l’université au Québec.
Transdisciplinarité et pratique clinique en santé mentale : quels enjeux éthiques ?
Authors: Renaud Sandrine , Drolet Marie-Josée 
Published: April 2023

La transdisciplinarité est une avenue prometteuse pour rendre les soins et les services de santé mentale plus accessibles, mais peut induire des enjeux éthiques, lesquels ne sont pas actuellement documentés. L’étude présentée dans cet article, basée sur la typologie de Swisher et al. (2005), visait à décrire les enjeux éthiques rencontrés par une équipe transdisciplinaire qui intervient en santé mentale. Des entretiens qualitatifs semi-dirigés ont été réalisés pour recueillir les perceptions de dix membres de cette équipe transdisciplinaire. L’analyse des verbatim fait émerger des enjeux éthiques correspondant à trois unités de sens : 1) l’ambivalence à dépasser les frontières disciplinaires; 2) les conflits d’allégeance envers le référent axiologique de l’équipe; 3) les difficultés à partager la prise de décision. Lorsque ces enjeux éthiques se posent, certaines valeurs chères aux intervenantes ainsi que certains droits fondamentaux des usagères sont susceptibles d’être bafoués. Trois pistes de réflexion critique sont proposées pour adopter une pratique transdisciplinaire respectueuse de l’éthique.

Published: April 2023

ImportanceThere are limited data regarding COVID-19 outcomes and vaccine uptake and safety among people with myasthenia gravis (MG).ObjectiveTo investigate COVID-19–related outcomes and vaccine uptake among a population-based sample of adults with MG.Design, Setting, and ParticipantsThis population-based, matched cohort study in Ontario, Canada, used administrative health data from January 15, 2020, and August 31, 2021. Adults with MG were identified using a validated algorithm. Each patient was matched by age, sex, and geographic area of residence to 5 controls from the general population and from a cohort of individuals with rheumatoid arthritis (RA).ExposurePatients with MG and matched controls.Main Outcomes and MeasuresMain outcomes were COVID-19 infection and related hospitalizations, intensive care unit admissions, and 30-day mortality among patients with MG vs controls. Secondary outcomes were uptake of COVID-19 vaccination among patients with MG vs controls.ResultsAmong 11 365 233 eligible Ontario residents, 4411 patients with MG (mean [SD] age, 67.7 [15.6] years; 2274 women [51.6%]) were matched to 22 055 general population controls (mean [SD] age, 67.7 [15.6] years; 11 370 women [51.6%]) and 22 055 controls with RA (mean [SD] age, 67.7 [15.6] years; 11 370 women [51.6%]). In the matched cohort, 38 861 of 44 110 individuals (88.1%) were urban residents; in the MG cohort, 3901 (88.4%) were urban residents. Between January 15, 2020, and May 17, 2021, 164 patients with MG (3.7%), 669 general population controls (3.0%), and 668 controls with RA (3.0%) contracted COVID-19. Compared with general population controls and controls with RA, patients with MG had higher rates of COVID-19–associated emergency department visits (36.6% [60 of 164] vs 24.4% [163 of 669] vs 29.9% [200 of 668]), hospital admissions (30.5% [50 of 164] vs 15.1% [101 of 669] vs 20.7% [138 of 668]), and 30-day mortality (14.6% [24 of 164] vs 8.5% [57 of 669] vs 9.9% [66 of 668]). By August 2021, 3540 patients with MG (80.3%) vs 17 913 general population controls (81.2%) had received 2 COVID-19 vaccine doses, and 137 (3.1%) vs 628 (2.8%), respectively had received 1 dose. Of 3461 first vaccine doses for patients with MG, fewer than 6 individuals were hospitalized for MG worsening within 30 days of vaccination. Vaccinated patients with MG had a lower risk than unvaccinated patients with MG of contracting COVID-19 (hazard ratio, 0.43; 95% CI, 0.30-0.60).Conclusions and RelevanceThis study suggests that adults with MG who contracted COVID-19 had a higher risk of hospitalization and death compared with matched controls. Vaccine uptake was high, with negligible risk of severe MG exacerbations after vaccination, as well as evidence of effectiveness. The findings support public health policies prioritizing people with MG for vaccination and new COVID-19 therapeutics.

AbstractPurposeQuality control (QC) is performed routinely through professional guidelines. However, the recommended QC frequency may not be optimal among different institutional settings. Here we propose a novel method for determining the optimal QC frequency using risk matrix (RM) analysis.Methods and materialsA newly installed Magnetic Resonance linac (MR‐linac) was chosen as the testing platform and six routine QC items were investigated. Failures of these QC items can adversely affect treatment outcome for the patient. Accordingly, each QC item with its assigned frequency forms a unique failure mode (FM). Using FM‐effect analysis (FMEA), the severity (S), occurrence (O), and detection (D) of each FM was obtained. Next, S and D based on RM was used to determine the appropriate QC frequency. Finally, the performance of new frequency for each QC item was evaluated using the metric E = O/D.ResultsOne new QC frequency was the same as the old frequency, two new QC frequencies were less than the old ones, and three new QC frequencies were higher than the old ones. For six QC items, E values at the new frequencies were not less than their values at the old frequencies. This indicates that the risk of machine failure is reduced at the new QC frequencies.ConclusionsThe application of RM analysis provides a useful tool for determining the optimal frequencies for routine linac QC. This study demonstrated that linac QC can be performed in a way that maintains high performance of the treatment machine in a radiotherapy clinic.

AbstractPurposeTo study and analyze the effect of the use of a thin guide‐wire instead of a Foley catheter for urethral definition in prostate stereotactic body radiation therapy (SBRT) treatments and to compare treatment parameters in both situations.Material and MethodsThirty‐seven prostate SBRT patients were employed in this study. A Foley catheter was employed in nine of them, and a guide‐wire was employed in the other 28 patients. For each of the 28 patients in which the guide‐wire was employed, a comparison between urethral positions in both situations was performed, allowing for a margin definition of the urethra when a Foley catheter was employed. Displacements of the prostate during treatment were obtained, allowing for an analysis of prostate positions in both situations. Also, different treatment parameters such as the number of treatment interruptions, couch movements performed, and x‐rays needed were gathered.ResultsLarge differences between urethral positions can be found in the anterior‐posterior (AP) directions compared to those in the lateral (LAT) direction. Differences are also larger in areas closer to the base of the prostate, where margins applied in the case of using a Foley catheter are 16 mm with a mean displacement of 6 mm in the posterior direction. No differences in the treatment parameters were found during treatment in both situations. The difference found in absolute prostate pitch rotations suggests that the Foley catheter provokes a shift of the prostate position, which does not occur when employing the guide‐wire.ConclusionsFoley catheters shift the urethral position, making them a wrong surrogate of the urethra when no catheters are present. The margins needed to assess uncertainties introduced by the use of a Foley catheter are larger than those usually applied. The use of a Foley catheter did not present any additional difficulty during treatment delivery in terms of images employed or interruptions produced.

AbstractA green textile‐based conductor with controllable electrical resistance change with deformation and transiency (i.e., dissolution in water) will be the holy grail in wearable electronics since it can satisfy divergent needs with a single solution and be sustainable simultaneously. Nevertheless, designing such material is challenging since opposite requirements shall be satisfied. To solve such a problem, cotton is functionalized using conductive inks made of graphene or carbon nanofiber, a biodegradable polyvinyl alcohol binder, and environmentally friendly solvents. The electrical resistance shows an anisotropic response to bending depending on the composition of the coating and the stress direction, functioning either as a deformable compliant electrode or a tunable piezoresistor. Indeed, it can withstand thousands of bending cycles with a change in resistance of less than 5% or change its resistance by many orders of magnitude with the same deformation thanks to the combination of cotton twill and different nanofillers. A simple modification in the binder composition adding waterborne polyurethane allows the coating to go from entirely transient in water within minutes to withstanding simulated washing cycles for hours without losing its electrical conductivity. This green versatile conductor may serve opposing needs by altering the material composition and the deformation direction.

Published: April 2023

AbstractThe large‐scale production of 2D transition metal dichalcogenides (TMDs) is essential to realize their industrial applications. Chemical vapor deposition (CVD) has been considered as a promising method for the controlled growth of high‐quality and large‐scale 2D TMDs. During a CVD process, the substrate plays a crucial role in anchoring the source materials, promoting the nucleation and stimulating the epitaxial growth. It thus significantly affects the thickness, microstructure, and crystal quality of the products, which are particularly important for obtaining 2D TMDs with expected morphology and size. Here, an insightful review is provided by focusing on the recent development associated with the substrate engineering strategies for CVD preparation of large‐scale 2D TMDs. First, the interaction between 2D TMDs and substrates, a key factor for the growth of high‐quality materials, is systematically discussed by combining the latest theoretical calculations. Based on this, the effect of various substrate engineering approaches on the growth of large‐area 2D TMDs is summarized in detail. Finally, the opportunities and challenges of substrate engineering for the future development of 2D TMDs are discussed. This review might provide deep insight into the controllable growth of high‐quality 2D TMDs toward their industrial‐scale practical applications.

AbstractA new straight forward approach to create nanoporous polymer membranes with well defined average pore diameters is presented. The method is based on fast mechanical deformation of highly entangled polymer films at high temperatures and a subsequent quench far below the glass transition temperature Tg. The process is first designed generally by simulation and then verified for the example of polystyrene films. The methodology does not need any chemical processing, supporting substrate, or self assembly process and is solely based on polymer inherent entanglement effects. Pore diameters are of the order of ten polymer reptation tube diameters. The resulting membranes are stable over months at ambient conditions and display remarkable elastic properties.

AbstractDetermination of a reaction pathway is an important issue for the optimization of reactions. However, reactions in solid‐state compounds have remained poorly understood because of their complexity and technical limitations. Here, using state‐of‐the‐art high‐speed time‐resolved synchrotron X‐ray techniques, the topochemical solid‐gas reduction mechanisms in layered perovskite Sr3Fe2O7−δ (from δ ∼ 0.4 to δ = 1.0), which is promising for an environmental catalyst material is revealed. Pristine Sr3Fe2O7−δ shows a gradual single‐phase structural evolution during reduction, indicating that the reaction continuously proceeds through thermodynamically stable phases. In contrast, a nonequilibrium dynamically‐disordered phase emerges a few seconds before a first‐order transition during the reduction of a Pd‐loaded sample. This drastic change in the reaction pathway can be explained by a change in the rate‐determining step. The synchrotron X‐ray technique can be applied to various solid‐gas reactions and provides an opportunity for gaining a better understanding and optimizing reactions in solid‐state compounds.
Reversing Free‐Electron Transfer of MoS2+x Cocatalyst for Optimizing Antibonding‐Orbital Occupancy Enables High Photocatalytic H2 Evolution

Published: April 2023

AbstractThe interaction between a co‐catalyst and photocatalyst usually induces spontaneous free‐electron transfer between them, but the effect and regulation of the transfer direction on the hydrogen‐adsorption energy of the active sites have not received attention. Herein, to steer the free‐electron transfer in a favorable direction for weakening S−Hads bonds of sulfur‐rich MoS2+x, an electron‐reversal strategy is proposed for the first time. The core–shell Au@MoS2+x cocatalyst was constructed on TiO2 to optimize the antibonding‐orbital occupancy. Research results reveal that the embedded Au can reverse the electron transfer to MoS2+x to generate electron‐rich S(2+δ)− active sites, thus increasing the antibonding‐orbital occupancy of S−Hads in the Au@MoS2+x cocatalyst. Consequently, the increase in the antibonding‐orbital occupancy effectively destabilizes the H 1s‐p antibonding orbital and weakens the S−Hads bond, realizing the expedited desorption of Hads to rapidly generate a lot of visible H2 bubbles. This work delves deep into the latent effect of the photocatalyst carrier on cocatalytic activity.

AbstractAir pollution is currently a huge threat to human health, which leads to heavy demand for efficient air filters. Herein, this work reports a facile and scalable strategy to fabricate a multilevel structure PA66@BN air filter to remove fine particles by combination solution blow spinning (SBS) and spraying. In this study, the composite membrane contains three structural features at multiscale: 1D polyamide 66 (PA66), 2D large surface area boron nitride nanosheets (BN), and 3D interconnecting network structure fiber membranes. The filtration efficiency of the composite membrane for PM2.5 and PM10 is >95%, the pressure drop is only 53 Pa, and the removal rate of 0.3 μm ultrafine particles also can reach 90%, which realizes the characteristics of high efficiency and low resistance of high‐quality filter. The presence of large transverse size BN increases the specific surface area and roughness of the nanofibers, reduces the probability of particle reflection and escape, and enhances the mechanical interception effect of the nanofibers on PM, while preserving the complex porous structure of 3D interconnection. Therefore, this study provides an economical and low‐energy consumption new strategy for fabricating air filters with special forms to cope with the increasingly serious air pollution.

AbstractCROP reactivity of organic coatings composed of three structurally different monomers with epoxy or oxetane derivatives was investigated, focusing on rheological and surface mechanical properties. Real‐time crosslinking behavior of CROP monomers was monitored using a rotational rheometer. Results of differential scanning calorimetry with in situ UV irradiation revealed that the ring opening reactivity of CROP monomers protonated by a photoacid generator (PAG) was correlated with the heat released during the exothermic polymerization reaction. In addition, reaction conversions of monomers with epoxy and oxetane groups were compared using Fourier transform infrared spectroscopy (FT‐IR) under dark curing conditions. Surface and internal mechanical properties of coating films, including adhesion with polycarbonate substrate, were comprehensively evaluated by nano‐indentation, nano‐scratch, and surface and interfacial cutting analysis system (SAICAS) tests. By understanding the unique crosslinking characteristics of each CROP monomer, the ternary CROP monomer system, optimally containing with ECC of 53.6 wt%, DOX of 22.9 wt%, and DEO of 15.3 wt%, exhibited improved crosslinking density (G′ from 104 to 107 Pa) and exceptional mechanical (with scratch resistance increasing from 7.11 to 16.17 mN for Lc1), adhesion (with crosscut resistance increasing from 0 to 5B), and transparency properties, surpassing the performance of unitary ECC coating system.
