Le jeu de rôle pour des apprentissages durables en anglais, langue seconde

Le fait de vivre dans la seule province bilingue au Canada place les étudiants néo-brunswickois francophones dans une situation qui exige de leur part qu’ils excellent dans leur langue seconde. L’apprentissage de l’anglais à titre de langue seconde s’avère pour certains étudiants un défi de taille qui s’exprime parfois par un désengagement, une démotivation, un malaise et, à la limite, un échec. Les auteurs de cet article partagent leur expérience d'une activité d'apprentissage qui s'est déroulée au Collège communautaire du Nouveau-Brunswick – Campus d’Edmundston : le jeu de rôle en classe d’anglais. Axé sur l'utilisation de mises en situation ou de problèmes à résoudre, celui-ci favorise à la fois le développement de la motivation à apprendre et les compétences langagières. Une fois la définition du jeu de rôle établie, les auteurs explicitent le déroulement de l'activité en mettant l'accent sur la réalisation de scénarios et ils déterminent les rôles respectifs de l'enseignant et des étudiants. Dans la foulée, ils mettent en lumière les nombreux avantages de cette formule pédagogique

Kinematics of the bow arm of violinists: effect of tempo, string played and play style and their interactions

8th World Congress of Biomechanics, DUBLIN, IRELANDE, 08-/07/2018 - 12/07/2018Bowed string musicians are especially at risk of upper limb injuries (Cayea and Manchester, 1998). While a few risk factors were identified, no causal relations could be found (Baadjou et al., 2016), highlighting the need for biomechanical investigations. Among the music parameters impacting violinists' biomechanics, the tempo, string played and play style have been investigated (Visentin and Shan, 2003; Berque and Gray, 2002). However, interactions between these parameters are not clear. Their knowledge could help defining relevant experimental research plans. The objective was to assess the interactions of the tempo, string played and play style on the bow arm biomechanic

Contrasting effects of acidification and warming on dimethylsulfide 2 concentrations during a temperate estuarine fall bloom mesocosm 3 experiment

The effects of ocean acidification and warming on the concentrations of dimethylsulfoniopropionate (DMSP) and dimethylsulfide (DMS) were investigated during a mesocosm experiment in the Lower St. Lawrence Estuary (LSLE) in the fall of 2014. Twelve mesocosms covering a range of pHT (pH on the total hydrogen ion concentration scale) from 8.0 to 7.2, corresponding to a range of CO2 partial pressures (pCO2) from 440 to 2900 μatm, at two temperatures (in situ and C5 °C; 10 and 15 °C) were monitored during 13 days. All mesocosms were characterized by the rapid development of a diatom bloom dominated by Skeletonema costatum, followed by its decline upon the exhaustion of nitrate and silicic acid. Neither the acidification nor the warming resulted in a significant impact on the abundance of bacteria over the experiment. However, warming the water by 5 °C resulted in a significant increase in the average bacterial production (BP) in all 15 °C mesocosms as compared to 10 °C, with no detectable effect of pCO2 on BP. Variations in total DMSP (DMSPt DparticulateCdissolved DMSP) concentrations tracked the development of the bloom, although the rise in DMSPt persisted for a few days after the peaks in chlorophyll a. Average concentrations of DMSPt were not affected by acidification or warming. Initially low concentrations of DMS (< 1 nmol L-1) increased to reach peak values ranging from 30 to 130 nmol L-1 towards the end of the experiment. Increasing the pCO2 reduced the averaged DMS concentrations by 66%and 69%at 10 and 15 °C, respectively, over the duration of the experiment. On the other hand, a 5 °C warming increased DMS concentrations by an average of 240% as compared to in situ temperature, resulting in a positive offset of the adverse pCO2 impact. Significant positive correlations found between bacterial production and concentrations of DMS throughout our experiment point towards temperatureassociated enhancement of bacterial DMSP metabolism as a likely driver of the mitigating effect of warming on the negative impact of acidification on the net production of DMS in the LSLE and potentially the global ocean.Fil: Benard, Robin.

Exposure to wind turbine noise: Perceptual responses and reported health effects

Health Canada, in collaboration with Statistics Canada, and other external experts, conducted the Community Noise and Health Study to better understand the impacts of wind turbine noise (WTN) on health and well-being. A cross-sectional epidemiological study was carried out between May and September 2013 in southwestern Ontario and Prince Edward Island on 1238 randomly selected participants (606 males, 632 females) aged 18-79 years, living between 0.25 and 11.22 km from operational wind turbines. Calculated outdoor WTN levels at the dwelling reached 46 dBA. Response rate was 78.9% and did not significantly differ across sample strata. Self-reported health effects (e.g., migraines, tinnitus, dizziness, etc.), sleep disturbance, sleep disorders, quality of life, and perceived stress were not related to WTN levels. Visual and auditory perception of wind turbines as reported by respondents increased significantly with increasing WTN levels as did high annoyance toward several wind turbine features, including the following: noise, blinking lights, shadow flicker, visual impacts, and vibrations. Concern for physical safety and closing bedroom windows to reduce WTN during sleep also increased with increasing WTN levels. Other sample characteristics are discussed in relation to WTN levels. Beyond annoyance, results do not support an association between exposure to WTN up to 46 dBA and the evaluated health-related endpoints

Molecular mechanisms of cell death: recommendations of the Nomenclature Committee on Cell Death 2018.

Over the past decade, the Nomenclature Committee on Cell Death (NCCD) has formulated guidelines for the definition and interpretation of cell death from morphological, biochemical, and functional perspectives. Since the field continues to expand and novel mechanisms that orchestrate multiple cell death pathways are unveiled, we propose an updated classification of cell death subroutines focusing on mechanistic and essential (as opposed to correlative and dispensable) aspects of the process. As we provide molecularly oriented definitions of terms including intrinsic apoptosis, extrinsic apoptosis, mitochondrial permeability transition (MPT)-driven necrosis, necroptosis, ferroptosis, pyroptosis, parthanatos, entotic cell death, NETotic cell death, lysosome-dependent cell death, autophagy-dependent cell death, immunogenic cell death, cellular senescence, and mitotic catastrophe, we discuss the utility of neologisms that refer to highly specialized instances of these processes. The mission of the NCCD is to provide a widely accepted nomenclature on cell death in support of the continued development of the field
