How do International Trainee Teachers and Mentors Respond to Cross-cultural Mentoring Relationships?

Forty-one percent of the trainee teachers who trained to teach modern foreign languages (MFL) at the University of Worcester between September 2008 and June 2011 were international trainee teachers who spoke English as an additional language. International trainee teachers and home trainee teachers do not usually share the same mother tongue or the same culture. A small-scale research project was conducted using both qualitative and quantitative methods to consider international trainee teacher and mentor attitudes to cross-cultural mentoring relationships. The study found that it was critically important to facilitate communication between mentor and trainee teachers in order to support the development of cross-cultural mentoring relationships, to help avoid misunderstandings and to enable trainee teachers to meet their potential

Introducing Secondary Professional/Post Graduate Certificate in Education (PGCE) Student Teachers in Modern Languages to Content and Language Integrated Learning (CLIL)

The revised Modern Foreign Languages (MFL) Key Stage 3 National Curriculum was launched in 2008. It encourages the “use of the target language in connection with topics and issues that are engaging and may be related to other areas of the curriculum” (National Curriculum, 2008). In order to account for these national developments, the Initial Teacher Training Programme for Modern Languages was reviewed in 2008 and a bid to take part in the Integrated Learning Network Project funded by the TDA was submitted successfully in September 2008. The rationale for the project was twofold. Firstly, it was to attempt to adopt a CLIL approach to language teaching and secondly was to give all the Secondary PGCE student teachers in Modern Languages the opportunity to experiment with the CLIL methodology. CLIL is increasingly being recognised as good practice in schools and it is perceived as motivational. Therefore, it may have an impact on student teachers’attitudes towards Modern Languages pedagogy and it may inform their practice as newly qualified teachers

Heurs et malheurs de la littérature dans les manuels de FLE destinés au secondaire en Angleterre

En 2016, suite à la réforme des programmes du secondaire en langues vivantes en Angleterre, la littérature refait son entrée dans les manuels. Après avoir étudié l’accueil de cette réforme et la manière dont se projetaient des enseignants en formation initiale (Ulma & Schäfer, 2018) et les examens sanctionnant les études secondaires (Ulma & Schäfer, 2022), nous proposons de poursuivre notre analyse de ce que révèlent la présence et le traitement de la littérature en étudiant les manuels de FLE destinés au secondaire. Quels sont les valeurs, les représentations et les idéaux véhiculés par la manière dont sont choisis, mis en scène (assemblages et discours d’escorte), étudiés (activités didactiques) les textes littéraires ? Quelles informations cette analyse nous donne-t-elle sur la fonction de la littérature en classe de langue voulue par l’institution au travers des programmes et de leur interprétation par les concepteurs de manuels ? Que nous disent ces choix, enfin, de la vision de la littérature en français des décideurs à l’origine des programmes et de la sélection des œuvres ? Nous appuierons notre étude sur les manuels conçus par les trois grands organismes institutionnellement chargés des syllabus, des manuels et des examens, AQA, Edexcel et Eduqas, en recourant à la grille d’analyse que nous avions mise au point pour l’étude des sujets d’examen, en l’adaptant au support, et en la mettant en regard d’études similaires sur la lecture de littérature en classe de langue (Adli & Mahmoudi, 2017). La période considérée court de 2016 à 2022, les évolutions successives des programmes, et par conséquent des examens, ayant abouti à la disparition progressive et désormais annoncée de la littérature au profit d’un recentrage sur le lexique, la grammaire et la phonétique. Nous faisons l’hypothèse que le ver était dans le fruit dès l’origine, et que tenir les objectifs des programmes et ceux des examens (qui formatent les pratiques) relevait d’une double contrainte qui ne pouvait que nuire à la présence de la littérature en classe de langue vivante : comment les manuels ont-ils composé avec cette intenable commande

Cancer targeting with biomolecules: a comparative study of photodynamic therapy efficacy using antibody or lectin conjugated phthalocyanine-PEG gold nanoparticles

The functionalisation of therapeutic nanoparticle constructs with cancer-specific biomolecules can enable selective tumour accumulation and targeted treatment. Water soluble gold nanoparticles (ca. 4 nm) stabilised by a mixed monolayer of a hydrophobic zinc phthalocyanine photosensitiser (C11Pc) and hydrophilic polyethylene glycol (PEG) have been prepared. The C11Pc-PEG gold nanoparticle constructs were further functionalised with jacalin, a lectin specific for the cancer-associated Thomsen–Friedenreich (T) carbohydrate antigen, or with monoclonal antibodies specific for the human epidermal growth factor receptor-2 (HER-2). The two biofunctionalised nanoparticle conjugates produced similar levels of singlet oxygen upon irradiation at 633 nm. Importantly, both nanoparticle conjugates demonstrated extensive, yet comparable, phototoxicity in HT-29 colorectal adenocarcinoma cells (80–90%) and in SK-BR-3 breast adenocarcinoma cells (>99%). Non-conjugated C11Pc-PEG gold nanoparticles were only minimally phototoxic. Lysosomal colocalisation studies performed with the HT-29 colon cancer cells and the SK-BR-3 breast cancer cells revealed that both nanoparticle conjugates were partially localised within acidic organelles, which is typical of receptor-mediated endocytosis. The similarity of the targeted PDT efficacy of the two biofunctionalised C11Pc-PEG gold nanoparticles is discussed with respect to targeting ligand binding affinity and cell surface antigen density as key determinants of targeting efficiency. This study highlights how targeting small cell-surface molecules, such as the T antigen, can mediate a selective photodynamic treatment response which is similar to that achieved when targeting overexpressed protein receptors, such as HER-2. The high prevalence of the T antigen present on the cellular surface of primary tumours emphasises the broad potential applications for lectin-targeted therapies

Prevalence and association of asthma and allergic sensitization with dietary factors in schoolchildren: data from the french six cities study

International audienceBackground: The prevalence of asthma and allergy has recently risen among children. This increase in prevalence might be related to various factors, particularly diet. The aim of this study is to assess the prevalence and association of asthma and allergic sensitization with dietary factors in the French Six Cities Study. Methods: Cross-sectional studies were performed among 7432 schoolchildren aged 9-11 years in Bordeaux, Clermont-Ferrand, Creteil, Marseille, Reims, and Strasbourg. Parental questionnaires, based on the International Study on Asthma and Allergies in Childhood (ISAAC), were used to collect information on allergic diseases and potential exposure factors including a food frequency questionnaire to evaluate dietary habits. Skin prick testing to common allergens for allergic sensitization and bronchial hyper-responsiveness (BHR) testing to exercise were performed. Confounders control was performed with multiple logistic regressions. Results: Asthma symptoms, asthma and allergic sensitization were more prevalent in boys than in girls and were more prevalent in the South than in the North of France. After adjustment for confounders, fruit juice intake was associated with a low prevalence of lifetime asthma (ORa [95 % CI]; 0.73 [0.56-0.97]), butter intake was positively associated with atopic wheeze (1.48 [1.07-2.05]) and having lunch at the canteen 1-2 times/week compared to never or occasionally was associated with a lower prevalence of past year wheeze (0.71 [0.52-0.96]), lifetime asthma (0.76 [0.60-0.96]) and allergic sensitization (0.80 [0.67-0.95]). Meat intake was inversely related to past year wheeze among atopic children (0.68 [0.50-0.98]) while fast food consumption and butter intake were associated with an increase prevalence of asthma (2.39 [1.47-3.93] and 1.51 [1.17-2.00] respectively). Fish intake was associated with a lower prevalence of asthma among non-atopic children (0.61 [0.43-0.87]. None of the dietary factors was associated with BHR. Conclusions: Diet is associated with wheeze, asthma and allergic sensitization but not with BHR in children. These results provide further evidence that adherence to a healthy diet including fruits, meat and fish seems to have a protective effect on asthma and allergy in childhood. However, prospective and experimental studies are needed to provide causal evidence concerning the effect of diet on asthma and atopy

Understanding the roles of the P2X7 receptor in solid tumour progression and therapeutic perspectives

P2X7 is an intriguing ionotropic receptor for which the activation by extracellular ATP induces rapid inward cationic currents and intracellular signalling pathways associated with numerous physiological processes such as the induction of the inflammatory cascade, the survival and proliferation of cells. In contrast, long-term stimulation of P2X7 is generally associated with membrane permeabilisation and cell death. Recently, P2X7 has attracted great attention in the cancer field, and particularly in the neoplastic transformation and the progression of solid tumours. A growing number of studies were published; however they often appeared contradictory in their results and conclusions. As such, the involvement of P2X7 in the oncogenic process remains unclear so far. The present review aims to discuss the current knowledge and hypotheses on the involvement of the P2X7 receptor in the development and progression of solid tumours, and highlight the different aspects that require further clarification in order to decipher whether P2X7 could be considered as a cancer biomarker or as a target for pharmacological intervention. This article is part of a Special Issue entitled: Membrane channels and transporters in cancers

Ontologías en disputa: Diálogos entre la antropología y la arqueología para la problematización de paisajes regionals

Objetivo/contexto: Hacia finales del siglo XX, el dualismo ontológico con el que antropólogos y arqueólogos nos hemos formado teórica y metodológicamente ha sido cuestionado y puesto en debate. En este contexto, nuestro objetivo es exponer críticamente los trabajos que se están realizando y que contribuyen a problematizar los paisajes enredados de existencias, materialidades, saberes, sentidos o prejuicios pasados y presentes, y con ello a restablecer el diálogo entre la antropología social y la arqueología. Metodología: Exponemos el estado actual de la apertura ontológica en clave latinoamericana. Problematizamos la noción de paisaje como concepto que permite diálogos teórico-metodológicos entre la antropología y la arqueología, así como con otras disciplinas. También presentamos ejes de comunicación y diálogo entre los artículos que forman parte del presente dossier para finalizar con los desafíos por delante en cuanto a traspasar fronteras disciplinarias, temporales y espaciales. Conclusiones: En contextos de históricas relaciones de poder, de profundas crisis socio-ambientales, los principales desafíos de la apertura ontológica serían: 1) generar referentes teóricos permeables a diversas disciplinas y saberes; 2) consolidar metodologías que integren lo etnográfico con lo arqueológico; 3) alentar diálogos constructivos hacia y con otras disciplinas y saberes, y 4) propiciar la comprensión del entramado político actual y la generación de políticas públicas que permitan diversas formas de relacionamiento con el entorno. Originalidad: El restablecimiento de diálogos entre la arqueología y la antropología social desde las aperturas ontológicas tiene el potencial de discutir cómo en determinados contextos se concretan y/o disputan paisajes y modos hegemónicos de habitar en el mundo, así como se problematizan los usos políticos del pasado y las políticas de uso del espacio y el ambiente.Objective/context: Towards the end of the 20th century, the ontological dualism with which anthropologists and archaeologists have trained us theoretically and methodologically has been questioned and debated. In this context, our objective is to critically expose the works that are being carried out and that contribute to problematizing the landscapes entangled with past and present existences, materialities, knowledge, senses or prejudices, and, with it, to re-establish the dialogue between social anthropology and archaeology. Methodology: We expose the current state of the ontological opening in Latin American code. We problematize the notion of landscape as a concept that allows theoretical-methodological dialogues between anthropology and archaeology, as well as with other disciplines. We also present axes of communication and dialogue between the articles that are part of this dossier, to end with the challenges ahead in terms of crossing disciplinary, temporal and spatial borders. Conclusions: In contexts of historical power relations, of deep socio-environmental crises, the main challenges for an ontological opening would be: 1) to generate theoretical referents permeable to various disciplines and fields of knowledge; 2) to consolidate methodologies that integrate the ethnographic with the archaeological; 3) to encourage constructive dialogues towards and with other disciplines and fields of knowledge; and 4) to propitiate the understanding of the current political framework and the generation of public policies that allow for diverse forms of relation with the environment. Originality: The re-establishment of dialogues between archaeology and social anthropology from ontological openings has the potential to discuss how, in certain contexts, landscapes and hegemonic ways of living are concretized and/or disputed, as well as the political uses of the past and the policies of use of space and the environment.Objetivo/contexto: No final do século XX, o dualismo ontológico com o qual antropólogos e arqueólogos se formaram teórica e metodologicamente vem sendo questionado e colocado em debate. Nesse contexto, nosso objetivo é expor criticamente os trabalhos que estão sendo realizados e que contribuem para problematizar as paisagens permeadas de existências, materialidades, saberes, sentidos ou preconceitos passados e presentes, e, com isso, reestabelecer o diálogo entre a antropologia social e a arqueologia. Metodologia: Expomos o estado atual da abertura ontológica no âmbito latino-americano. Problematizamos a noção de paisagem como conceito que permite diálogos teórico-metodológicos entre a antropologia e a arqueologia, assim como outras disciplinas. Também apresentamos eixos de comunicação e diálogo entre os artigos que fazem parte do presente dossiê para finalizar com os desafios que temos adiante sobre ultrapassar fronteiras disciplinares, temporais e espaciais. Conclusões: Em contextos de históricas relações de poder, de profundas crises socioambientais, os principais desafios para uma abertura ontológica seriam: 1) gerar referentes teóricos permeáveis a diversas disciplinas e saberes; 2) consolidar metodologias que integrem o etnográfico com o arqueológico; 3) promover diálogos construtivos com outras disciplinas e saberes; e 4) propiciar a compreensão da estrutura política atual e a geração de políticas públicas que permitam as diversas formas de relacionamentos com o ambiente. Originalidade: O reestabelecimento de diálogos entre a arqueologia e a antropologia social a partir das aberturas ontológicas tem o potencial de discutir como, em determinados contextos, se concretizam e/ou disputam paisagens e modos hegemônicos de habitar, bem como se problematizam os usos políticos do passado e as políticas de uso do espaço e do ambiente.Fil: Saldi, Leticia.
