Analyse de formules employées par le gouvernement et de leurs stratégies de cadrage sous-jacentes pendant le printemps érable québécois de 2012

Notre recherche porte sur la stratégie discursive du gouvernement pendant le printemps érable québécois de 2012, particulièrement sur les formules qu’il a employées afin d’influencer l’opinion publique. Au moyen d’une analyse de contenu de 100 articles de cinq quotidiens québécois, nous avons étudié 152 formules au regard de leur distribution dans le temps, des entités qu’elles ont ciblées, des locuteurs les ayant employées et des stratégies de cadrage qu’elles sous-entendent. L’analyse révèle plusieurs aspects, notamment la présence de multiples locuteurs et de cibles s’inscrivant dans la stratégie discursive. Le discours et les formules employées ont cherché à délégitimer les étudiants, mais aussi à cadrer l’image du gouvernement lui-même et celle de ses adversaires politiques. Le concept de formule permet de produire des unités d’analyse pouvant être étudiées empiriquement au regard du cadrage et de diversifier les recherches menées sur l’événement sociodiscursif qu’est le printemps érable.Our research focuses on the government’s discursive strategy during the 2012 Maple Spring in Quebec, particularly on the formulas used to influence public opinion. Through a content analysis of 100 articles from five Quebec newspapers, we studied 152 formulas with regard to their distribution in time, the entities they targeted, the speakers who used them, and the framing strategies they conveyed. The analysis revealed several aspects, including the presence of multiple speakers and targets as part of the discursive strategy. The discourse and the formulas that were used sought to delegitimize the students, but also to frame the image of the government itself, and that of its political opponents. Eventually, the concept of formula allowed us to produce units of analysis that could be studied empirically with regard to framing, and to contribute to the analysis of the Maple Spring as a socio-discursive event

Long term evaluation of disease progression through the quantitative magnetic resonance imaging of symptomatic knee osteoarthritis patients: correlation with clinical symptoms and radiographic changes

The objective of this study was to further explore the cartilage volume changes in knee osteoarthritis (OA) over time using quantitative magnetic resonance imaging (qMRI). These were correlated with demographic, clinical, and radiological data to better identify the disease risk features. We selected 107 patients from a large trial (n = 1,232) evaluating the effect of a bisphosphonate on OA knees. The MRI acquisitions of the knee were done at baseline, 12, and 24 months. Cartilage volume from the global, medial, and lateral compartments was quantified. The changes were contrasted with clinical data and other MRI anatomical features. Knee OA cartilage volume losses were statistically significant compared to baseline values: -3.7 ± 3.0% for global cartilage and -5.5 ± 4.3% for the medial compartment at 12 months, and -5.7 ± 4.4% and -8.3 ± 6.5%, respectively, at 24 months. Three different populations were identified according to cartilage volume loss: fast (n = 11; -13.2%), intermediate (n = 48; -7.2%), and slow (n = 48; -2.3%) progressors. The predictors of fast progressors were the presence of severe meniscal extrusion (p = 0.001), severe medial tear (p = 0.005), medial and/or lateral bone edema (p = 0.03), high body mass index (p < 0.05, fast versus slow), weight (p < 0.05, fast versus slow) and age (p < 0.05 fast versus slow). The loss of cartilage volume was also slightly associated with less knee pain. No association was found with other Western Ontario McMaster Osteoarthritis Index (WOMAC) scores, joint space width, or urine biomarker levels. Meniscal damage and bone edema are closely associated with more cartilage volume loss. These data confirm the significant advantage of qMRI for reliably measuring knee structural changes at as early as 12 months, and for identifying risk factors associated with OA progression

The Dichotomous Pattern of IL-12R and IL-23R Expression Elucidates the Role of IL-12 and IL-23 in Inflammation

IL-12 and IL-23 cytokines respectively drive Th1 and Th17 type responses. Yet, little is known regarding the biology of these receptors. As the IL-12 and IL-23 receptors share a common subunit, it has been assumed that these receptors are co-expressed. Surprisingly, we find that the expression of each of these receptors is restricted to specific cell types, in both mouse and human. Indeed, although IL-12Rβ2 is expressed by NK cells and a subset of γδ T cells, the expression of IL-23R is restricted to specific T cell subsets, a small number of B cells and innate lymphoid cells. By exploiting an IL-12- and IL-23-dependent mouse model of innate inflammation, we demonstrate an intricate interplay between IL-12Rβ2 NK cells and IL-23R innate lymphoid cells with respectively dominant roles in the regulation of systemic versus local inflammatory responses. Together, these findings support an unforeseen lineage-specific dichotomy in the in vivo role of both the IL-12 and IL-23 pathways in pathological inflammatory states, which may allow more accurate dissection of the roles of these receptors in chronic inflammatory diseases in humans

Survey of imazethapyr-resistant common ragweed (Ambrosia artemisiifolia L.) in Quebec

Common ragweed (Ambrosia artemisiifolia L.) is widespread in soybean (Glycine max L.) fields in southern Québec. Biotypes resistant to ALS (group 2) herbicides are commonly reported in conventional crops where these herbicides are used. Reported cases are voluntary and potentially underestimate the occurrence of resistance. A survey was therefore undertaken in 2014 and 2015 in soybean fields treated with a Group 2 herbicide. Common ragweed seeds were collected from 123 fields. Seedlings were grown and tested for resistance using the recommended rate of imazethapyr (100.8 g a.e. ha-1). Weed populations were classified as susceptible, developing resistance (less than one third of plants classified as resistant) or resistant (at least one third of plants were resistant). Twenty populations were then selected based on these resistance levels and treated with four doses of the herbicide (0, 100.8, 201.6, and 403.2 g a.e. ha-1). Resistance to imazethapyr was detected in 81% of samples (21.1% were classified as developing resistance and 59.4% were classified as resistant). Populations classified as developing resistance had a resistance factor of 1.04, while populations classified as resistant had a resistance factor greater than 5. These results confirm the presence of multiple populations of imazethapyr-resistant common ragweed in Quebec.La petite herbe à poux (Ambrosia artemisiifolia L.) est très fréquente dans les champs de soya (Glycine max L.) du Québec méridional. Des biotypes résistants aux herbicides qui inhibent l’acétolactate synthase (ALS) (Groupe 2) sont fréquemment signalés dans les champs où ces herbicides sont utilisés. Les cas rapportés se font sur une base volontaire et sous-estiment potentiellement la fréquence réelle de la résistance. Une enquête a donc été réalisée en 2014 et en 2015 dans des champs de soya traités avec un herbicide du groupe 2. Des graines ont été récoltées dans 123 champs. Des plantules ont été testées pour leur résistance avec une dose recommandée d’imazéthapyr (100,8 g e.a. ha-1). Les populations ont été classifiées sensibles, résistantes (au moins un tiers des plants étaient résistants) ou présentant une résistance en développement (moins du tiers des plants étaient résistants). Vingt populations ont ensuite été sélectionnées selon leur degré de résistance et traitées avec quatre doses d’herbicide (0; 100,8; 201,6 et 403,2 g e.a. ha-1). De la résistance à l’imazéthapyr a été détectée dans 81 % des échantillons (21,1 % classifiés avec une résistance en développement et 59,4 % classifiés résistants). Le facteur de résistance des populations avec de la résistance en développement était de 1,04 et celui des populations résistantes était supérieur à 5. Ces résultats confirment la présence de multiples populations de petite herbe à poux résistantes à l’imazéthapyr au Québec

La formation J'enseigne à distance : un levier pour le développement de la compétence numérique (niveaux préscolaire /primaire)

Dans le contexte de la pandémie de la COVID-19, le système d’éducation québécois est mis à l’épreuve. Les enseignantes à l’éducation préscolaire et au primaire doivent adapter leurs pratiques pour soutenir les apprentissages de leurs élèves à distance alors que beaucoup sont peu outillées pour le faire. Le développement de la formation J’enseigne à distance par l’Université TÉLUQ a permis à des acteurs des milieux de pratique et universitaire de réunir leurs expertises et de réfléchir ensemble aux pratiques favorables à l’enseignement virtuel en contexte de pandémie. Des retombées quant à la compétence numérique ont émergé de ce partenariat. Mots-clés: compétence numérique, enseignantes préscolaire\primaire, pandémie COVID-19, formation à distance, partenaria

Assessing quality indicators related to mental health emergency room utilization

Abstract Background This descriptive study compared 2014–15 to 2005–06 data on the quality of mental health services (MHS) in relation to emergency room (ER) use to assess the impact of the 2005 Quebec MH reform regarding access, continuity and appropriateness of care for patients with mental illnesses (PMI). Methods Data emanated from the Quebec Integrated Chronic Disease Surveillance System (Quebec/Canada). Participants (865,255 for 2014–15; 817,395 for 2005–06) were age 12 or over, with at least one MI, including substance use disorders (SUD), diagnosed during an ER visit, outpatient treatment or hospitalization. Variables included: access (ER use/frequency, hospitalization rates, outpatient consultations preceding an ER visit), care continuity (outpatient consultations following an ER visit/hospitalization, consecutive returns to the ERs), and care appropriateness (high ER use, recurrence of yearly ER visits, length of hospitalization). Frequency distributions were calculated on sex, age and geographic area for ER visits/hospitalizations in 2014–15, and between 2014 and 15 and 2005–06. Results PMI accounted for 12 % of the Quebec population in 2014–15 (n = 865,255), of whom 39% visited an ER for any reason. Amount and frequency of ER use and number/length of hospitalizations were almost twice as high for PMI versus patients without MI; 17% of PMI were also high/very high ER users and were frequently hospitalized. Among PMI, ER users were also frequent users of outpatient services despite a lack of follow-up appointments after ER visits or hospitalizations. Findings revealed some positive changes over time, such as decreased ER and hospitalization rates; yet overall access, continuity and appropriateness of care, as measured in this study, remained low. Conclusions This study demonstrated that the Quebec reform did not produce a substantial impact on ER use or substantially improved care, as hypothesized. Better access and continuity of care should be promoted to reduce the high prevalence of ER use among PMI. Quality improvement in MHS may be realized if ERs are supported by substantial and well-integrated community MH networks
