La cruauté, le rire, le sarcasme, l’histoire

Jean Jourdheuil appréhende la question de l’histoire et de ses potentialités à propos de deux pièces de théâtre de deux écrivains allemands, Heinrich von Kleist (1777-1811) et Heiner Müller (1929-1995), qui, en des temps différents, se sont trouvés sur certaines lignes de fracture de l’histoire européenne

Allio à distance de Brecht

Allio et le brechtisme… Non, Allio ou le brechtisme… J’hésite ! La formule n’est-elle pas trop limitative et, par-là, trop définitive ? Sur le rapport de René Allio à Brecht, ou du moins à ce qu’il a laissé : la distanciation en tête, je n’ai aucune certitude, aucun a priori. Peut-être, toutefois, aurais-je envie de quelques nuances sur la mise en place de ce syntagme figé, un peu trop vite décrété, un peu rapidement arrêté… Pourquoi ? Parce que – un ..

Cooperating Teachers\u27 Perceived Preparedness to Support Science Teacher Candidates for Culturally Sustaining Science Teaching

In the United States, many communities face challenges that require science, technology, engineering, and math (STEM) solutions. Those communities most affected by these challenges often lack opportunities in school to use their funds of knowledge as they develop STEM literacies that would equip them to address these challenges. With new national science standards and increasingly diverse student demographics in classrooms across the United States, teacher educators must utilize strategies that prepare science teacher candidates, who are predominantly White, with pedagogies that can support diverse learners in expanding their STEM literacies from their funds of knowledge. The problem of practice guiding this research was that within the shifting landscape of STEM education, too few science teachers are prepared to implement the new standards in ways that are culturally sustaining for their traditionally underserved learners. The purpose of this convergent mixed methods study was to describe cooperating teachers\u27 perceived preparedness to support science teacher candidates to use culturally sustaining pedagogies to inform practices and policies that influence STEM teacher preparation. To address the problem of practice quantitative and qualitative data were collected using a survey instrument and then analyzed through the lens of a conceptual framework developed called culturally sustaining science teaching. The findings suggest cooperating teachers feel prepared for the components of the culturally sustaining science teaching framework (curriculum, instruction, and relationships). No statistically significant differences were shown between the components but nuanced differences were apparent when quantitative mean score ranks and qualitative data were converged

NPC1L1 and SR-BI are involved in intestinal cholesterol absorption from small-size lipid donors

International audienceIn the human intestinal content after a meal, cholesterol is dispersed in a complex mixture of emulsified droplets, vesicles, mixed micelles and precipitated material. The aim of this study was to determine the contribution of the main intestinal cholesterol transporters (NPC1L1, SR-BI) to the absorption processes, using different cholesterol-solubilizing donors. Cholesterol donors prepared with different taurocholate concentrations were added to an apical medium of differentiated TC7/Caco-2 cells. As the taurocholate concentrations increased, cholesterol donor size decreased (from 712 to 7 nm in diameter), which enhanced cholesterol absorption in a dose-dependent manner (38-fold). Two transport processes were observed: (1) absorption from large donors exhibited low-capacity transport with no noticeable transporter contribution; (2) efficient cholesterol absorption occurs from small lipid donors (≤23 nm diameter), mainly due to NPC1L1 and SR-BI involvement. In addition, bile acids significantly increased mRNA and protein expression of NPC1L1, but not of SR-BI. In conclusion, bile acids present in the intestinal lumen and the micelles enhance intestinal cholesterol transport into the cell by two different regulatory processes: by reducing the lipid donor size, so that small-size mixed micelles can more easily access brush-border membrane transporters, and by increasing the expression level of the enterocyte NPC1L1. These mechanisms could account for the important inter-individual variations observed in cholesterol intestinal absorptio

René Allio

Les historiens et les spécialistes du théâtre et du cinéma n’auraient-ils pas tendance à sous-estimer René Allio et à le cantonner à ses activités les plus connues (décorateur chez Planchon, auteur de quelques films majeurs) ? Fort de ces questions (et des réponses probables), Double Jeu souhaitait contribuer à une reconnaissance de son œuvre et en inspirer l’étude. À titre d’incitation, l’on trouvera ici quelques articles consacrés à un cinéma qui n’a rien perdu de son exemplarité, ainsi qu’à de multiples activités (scénographie, scénarisation, décentralisation cinématographique) qu’il serait regrettable de négliger
