Le travail collectif enseignant : allant de soi, effet de mode convenu ou analyseur décalé de la professionnalité enseignante ?
Ce texte prend appui sur l'analyse des différents articles contributifs de ce numéro. Il propose de souligner combien une réflexion sur le travail collectif des enseignants invite à interroger le sens du travail éducatif et l'enjeu de la reconfiguration des tensions entre pratiques éducatives et fonctions sociales de l'enseignement.This text is based on the analysis of different contributing articles in this review. It proposes to emphasize reflection on the collective work of teachers invited to question the meaning of educational work and the issue of reconfiguration of the tensions between educational practices and social functions of education
Les mĂ©tiers de lâĂ©ducation et de la formation : une professionnalisation en tensions
Les textes officiels et/ou professionnels sur les formations initiales et/ou continues dans les mĂ©tiers adressĂ©s Ă autrui dĂ©fendent parfois avec vigueur une visĂ©e : la professionnalisation. Outre que ce terme de professionnalisation pourrait apparaĂźtre comme un effet de mode, il semble important dâen comprendre ses fondements, ses conditions dâĂ©mergence tant du point de vue des recherches en sciences de lâĂ©ducation que du point de vue des discours sur et pour la professionnalisation, ses valeurs ajoutĂ©es, ses retombĂ©es attendues. Cet article propose donc au lecteur un tour dâhorizon historique permettant dâexpliquer le succĂšs de cette notion. Il vise aussi Ă dĂ©finir le terme en le confrontant Ă dâautres notions ou concepts, et notamment ceux de professionnalitĂ© et de savoirs professionnels. Enfin, il cherche Ă mettre en Ă©vidence les grandes questions et enjeux contenus dans cet objectif de professionnalisation en montrant aussi quelles peuvent ĂȘtre les conditions gagnantes pour faire dâun parcours de formation et de dĂ©veloppement professionnel un vĂ©ritable processus de professionnalisation des professionnels de lâĂ©ducation ou de la formation en devenir

Une perspective bachelardienne pour lire et comprendre les situations d'aprentissage professionnel de la formation Ă l'enseignement
Ce texte prĂ©sente quelques rĂ©sultats prĂ©liminaires dâune recherche menĂ©e prĂ©sentement Ă lâInstitut de recherche sur les pratiques Ă©ducatives de lâUniversitĂ© de Sherbrooke. Cette recherche vise Ă comprendre comment les situations prĂ©sentes dans la formation Ă lâenseignement peuvent soutenir le fonctionnement et la rĂ©ussite de lâapprentissage professionnel des enseignants en formation. Nous cherchons Ă identifier les points de rencontre entre les situations dâactivitĂ© professionnelle, les situations dâapprentissage professionnel et les situations de formation. Nous tenterons dâanalyser le rĂŽle que peuvent jouer certains dispositifs visant Ă soutenir un processus de professionnalisation que nous dĂ©finissons au regard dâune finalitĂ© : la construction de savoirs professionnels. LâoriginalitĂ© de cette recherche est la convocation des travaux de Gaston Bachelard pour Ă©laborer le cadre thĂ©orique permettant la lecture et lâinterprĂ©tation des rĂ©sultats.This text presents a few preliminary results of research currently being conducted at the UniversitĂ© de Sherbrookeâs Research Institute on Educational Practices. The study seeks to understand how situations presented in teacher education can support the functioning and success of trainee teachersâ professional learning. The articleâs aim is to identify the points of convergence between situations of professional activity, situations of professional learning, and training situations. The text will attempt to analyze the role that can be played by certain training structures that seek to support a professionalization process that we define in terms of a general aim: the construction of professional knowledge. The originality of this research lies in that it draws on the work of Gaston Bachelard to develop a theoretical frame enabling a reading and interpretation of the results
« Déprofessionnalisation »
Le propos de ce texte est de dĂ©finir la dĂ©professionnalisation. Demailly et La Broise (2009), qui posent ce terme comme « sociologiquement difficile Ă employer et fortement polysĂ©mique » (p. 1), le prĂ©sentent principalement comme « un inverse de professionnalisation » (Ibid.). En Ă©pousant cette perspective, nous proposons de caractĂ©riser la dĂ©professionnalisation Ă partir de ses traces et de ses formes mais aussi en cherchant Ă identifier ses causes et ses consĂ©quences. Avant de dĂ©finir la dĂ©professionnalisation, il nous paraĂźt donc important de prĂ©senter, dans une premiĂšre partie, le construit qui, selon nous, la rĂ©vĂšle en creux. Prendre ainsi appui sur la dĂ©finition de la professionnalisation pour caractĂ©riser la dĂ©professionnalisation nous invite, dans une seconde partie, Ă esquisser les contextes et conditions dâĂ©mergence de cette rĂ©alitĂ© sociale. Dans une troisiĂšme partie, nous proposons au lecteur diffĂ©rentes dĂ©finitions de la dĂ©professionnalisation.The purpose of this paper is to define the de-professionalisation. Demailly and La Broise (2009), which presented this term as « sociologically difficult to use and highly polysemous » (p. 1), showing it primarily as a « reverse of professionalisation » (Ibid.). We suggest to characterize the de-professionalisation, from its traces and forms, but also by seeking to identify its causes and consequences. Before defining the de-professionalisation , it seems important to present, in the first part, the construction whose reveals it. We will first characterize de-professionalisation supporting by the definition of profesionalisation and that will invites us in a second part, to outline the contexts and conditions of emergence of this social reality. In the third part, we will propose somes definitions of de-professionalisation
External validation suggests Integrin beta 3 as prognostic biomarker in serous ovarian adenocarcinomas
<p>Abstract</p> <p>Background</p> <p>The majority of women with ovarian cancer are diagnosed in late stages, and the mortality rate is high. The use of biomarkers as prognostic factors may improve the treatment and clinical outcome of these patients. We performed an external validation of the potential biomarkers CLU, ITGB3, CAPG, and PRAME to determine if the expression levels are relevant to use as prognostic factors.</p> <p>Methods</p> <p>We analysed the gene expression of CLU, ITGB3, CAPG, and PRAME in 30 advanced staged serous adenocarcinomas with quantitative real-time polymerase chain reaction (QPCR) and the protein levels were analysed in 98 serous adenocarcinomas with western blot for semiquantitative analysis. Statistical differences in mRNA and protein expressions between tumours from survivors and tumours from deceased patients were evaluated using the Mann-Whitney U test.</p> <p>Results</p> <p>The gene and protein ITGB3 (Integrin beta 3) were significantly more expressed in tumours from survivors compared to tumours from deceased patients, which is in concordance with our previous results. However, no significant differences were detected for the other three genes or proteins CLU, CAPG, and PRAME.</p> <p>Conclusion</p> <p>The loss of ITGB3 expression in tumours from deceased patients and high expression in tumours from survivors could be used as a biomarker for patients with advanced serous tumours.</p
Study on the Expression and Clinical Significances of Lewis y Antigen and Integrin αv, ÎČ3 in Epithelial Ovarian Tumors
Objective: To detect the expression and clinical significances of Lewis y antigen and integrin αv, ÎČ3 in epithelial ovarian tumors, and to explore the expression correlation between Lewis y antigen and integrin αv, ÎČ3. Methods: Immunohistochemical staining was performed in 95 cases of epithelial ovarian cancer, 37 cases of borderline tumors, 20 cases of benign tumors, and 20 cases of normal ovarian tissue, for the detection of Lewis y antigen and integrin αv, ÎČ3 expressions, and to analyze the relationship between Lewis y antigen and integrin, and the relationship between clinical and pathological parameters of ovarian cancer. In addition, immunofluorescence double labeling was utilized to detect the expression correlation between Lewis y antigen and integrin αv, ÎČ3 in ovarian cancer. Results: In epithelial ovarian tumors, the expression rate of Lewis y antigen was 81.05%, significantly higher than that of borderline (51.53%) (P < 0.05) and benign (25%) (P < 0.01) tumors, and normal ovarian tissues (0) (P < 0.01). The expression rate of integrin αv, ÎČ3 in malignant epithelial ovarian tumors was 78.95% and 82.11%, respectively, significantly higher than that of the borderline (45.94%, 40.54%) (both P < 0.05), benign group (10.00%, 15.00%) (both P < 0.01) and normal ovary group (5%, 15%) (both P < 0.01). Conclusions: Lewis y and integrins αv, ÎČ3 are relevant to pelvic and abdominal diffusion and metastasis of ovarian cancer cells, suggesting that these two molecules mediate a boosting function for tumor metastasis
