La régulation de la glycémie : une étude de cas en première S
No full textL’enseignement/apprentissage de la régulation en biologie a fait l’objet
de différentes recherches en didactique (Schneeberger, 1992 ; Rumelhard,
1994). Cette étude s’intéresse à la régulation de la glycémie et propose
d’analyser des observations réalisées dans une classe de première S. En
reprenant en partie les résultats des recherches antérieures, nous nous
interrogeons sur les points suivants :
– la légitimité épistémologique de l’utilisation de la modélisation
systémique dans l’enseignement de la régulation de la glycémie ;
– la relation élève/modèle : la manière selon laquelle l’élève construit,
s’approprie et applique un modèle formel dans le cadre de la régulation de
la glycémie.
Outre une étude épistémologique, nous avons conduit une analyse
détaillée d’une séance de débat pour repérer comment les élèves parviennent
à appliquer un modèle formel à un cas particulier. Les outils d’analyse
du débat ont été conçus à partir des travaux de Martinand et Orange. Ce
type de travail contribue à montrer l’importance de l’activité langagière des
élèves dans l’élaboration du savoir
Le discours polyphonique des manuels de Biologie en Tunisie : exemple de la régulation de la glycémie
No full textLes auteurs des manuels scolaires participent à l’élaboration du texte du savoir scolaire à travers la production d’écrits dans lesquels ils exposent leurs conceptions à propos de la régulation de la glycémie et signalent les modèles auxquels ils se réfèrent. Ce discours dévoile aussi les discussions partagées par ces auteurs lors de la collaboration qui a permis l’écriture du manuel. Notre recherche se base sur l’étude des traces de l’activité langagière des auteurs dans le but de repérer les choix qu’ils effectuent pour modéliser la régulation de la glycémie. Nos résultats montrent la cohabitation de deux modèles distincts, qui se traduit par un des énoncés fortement polyphoniques. Nous revenons sur les fondements scientifiques et épistémologiques des choix des auteurs pour discuter l’expression de cette polyphonie ainsi que ses conséquences sur les objets de savoir produits par les auteurs.Textbook authors participate in the elaboration of the text of school knowledge through the production of writings in which they expose their conceptions about the regulation of blood glucose and report the models to which they refer. This discourse also reveals the discussions between these authors during the collaboration that allowed the textbook to be written. Our research is based on the study of the traces of the linguistic activity of the authors in order to identify the choices they make to model the regulation of blood glucose. Our results show the cohabitation of two distinct models, which results in a strongly polyphonic statement. We analyse the scientific and epistemological foundations of the authors’ choices to discuss the expression of this polyphony as well as its consequences on the objects of knowledge produced by the authors
Teaching and learning of glycemic control : modeling and language activity
No full textA la lumière des analyses des activités langagières du physiologiste Claude Bernard, nous étudions la création du sens dans trois manuels tunisiens et la construction d'un nouveau langage dans les débats des d'élève tunisiens pour rendre compte du phénomène de la régulation de la glycémie à travers des modèles. En proposant une stratégie innovante dans l'enseignement de la régulation de la glycémie, nous explicitons les étapes des démarches de modélisation suivies par les élèves. Le type d'analyse mené dans cette recherche a permis d'explorer les stratégies de synchronisation de la polyphonie inhérente au discours des scientifiques, des concepteurs de manuels et des élèves pour créer un nouveau sens et de pointer quelques conditions de possibilités pour aboutir à une synchronisation réussie même dans le cas d'une polyphonie complexe comme celle des élèves tunisiens qui sont bilingues.We use the analyses of the linguistic activities of the physiologist Claude to study the creation of the direction in three Tunisian textbooks. We study also the construction of a new language in the debates by proposing a strategy innovating in the teaching of the glycemic control. We clarify the stages of the approach of modeling followed by the pupils. Tunisian Pupil gives an account of the phenomenon of the glycemic control through models. The type of analysis carried out in this research made it possible to explore the strategies of synchronization of the polyphony inherent in the speech of the scientists, the authors of textbooks and the pupils to create a new sense. We highlighted some conditions of possibilities to lead to a successful synchronization, even in the case of a complex polyphony as that of the Tunisian pupils who are bilingual

Estellés in Manel Garcia Grau: from critical review to poetic presence
No full textL’objecte d’estudi de l’article és de fer una revisió a la presència i a la influència de Vicent Andrés Estellés en la formació literària i, sobretot, en la producció escrita de Manel Garcia Grau. D’una banda, s’hi comenten els seus treballs en prosa que tracten sobre Estellés, els quals són de crítica literària i d’estudi de la literatura, i també les seues col·laboracions periodístiques. D’altra banda, s’hi estudia la incorporació i la presència del poeta de Burjassot al llarg de tota la producció poètica de l’autor castellonenc, en les dues etapes de la seua evolució. El treball constata com Garcia Grau, en descobrir Estellés, en rep la influència en els primers llibres de poemes i alhora li ret homenatge mitjançant alguns textos; també com, després, l’estudia com a crític i estudiós de la literatura aprofundint-hi en la seua poesia; i com, finalment, una vegada en coneix millor l’obra i el llegat literari, l’incorpora en nous poemes dels llibres de maduresa des de la intertextualitat i la hipertextualitat amb textos estellesians. Tot plegat permet concloure que en la primera etapa poètica de Garcia Grau incorpora i afegeix Estellés com influència literària i mostra la seua presència en alguns poemes, mitjançant citacions, epígrafs, dedicatòries, homenatge al poeta…; i, en canvi, en la segona etapa, l’aprofita, l’utilitza i l’integra literàriament en la configuració dels seus textos tenint-lo com a referent i font de préstecs, com a model textual i fins i tot hipotext per a l’elaboració dels seus hipertextos. Aquest nou aprofitament d’Estellés deriva de l’estudi i anàlisi que mentrestant Garcia Grau n’ha fet en l’aprofundiment estellesià dels seus treballs en prosa, tant en col·laboracions periodístiques, com en articles de crítica literària i d’estudi de la literatura. El jove poeta castellonenc sempre va tenir com a punt de referència l’obra del poeta de Burjassot.The aim of the article is to review the presence and impact Vicent Andrés Estellés has on the literary formation and, above all, on the work written by Manel Garcia Grau. On the one hand, his prose works on Estellés are discussed, which include literary criticism and the study of literature, as well as his journalistic collaborations. On the other hand, the incorporation and presence of the poet born in Burjassot throughout the entire poetic production of Manel Garcia Grau are also studied, of course in both stages of his evolution. The work also notes how the latter, upon discovering Estellés, is influenced by his figure in his early books of poems and also pays tribute to him through some texts. It also examines how he later studied Estellés as a critic and scholar of literature, thus delving into his poetry. Finally, once he is more familiar with Estellés’ work and literary legacy, he includes him in new poems of his mature books through intertextuality and hypertextuality with Estellesian texts. In conclusion, in the first poetic stage of Garcia Grau, the author incorporates Estellés as a literary influence and shows his presence in some poems by means of quotations, epigraphs, dedications, tribute to the poet, etc. In contrast, in the second stage, he uses and integrates Estellés into the configuration of his texts, considering him a reference and a source of borrowings, a textual model, and even a hypotext for the preparation of its hypertexts. This new use of Estellés stems from the study and analysis that Garcia Grau conducted in the meantime on the Estellesian aspects of his prose works, both in journalistic collaborations, and in literary criticism and literature study articles. The young poet from Castellon always had as a point of reference the poetic work of the poet from Burjassot.Aquest estudi s’emmarca en el programa d’investigació del projecte «Les relacions hipertextuals en la literatura catalana (1939-1983)», CIAICO,/2021/143, de la Conselleria d’Innovació, Universitats, Ciència i Societat Digital de la Generalitat Valenciana

infância intitulado Tao, com texto Manel Ollé e ilustrações de Neus Caamaño,
uma obra de inspiração chinesa recentemente publicada em Portugal. O
objetivo deste trabalho é estudar um exemplo de literatura infantil, publicada
em contexto português, inspirada na filosofia chinesa, contribuindo para a
popularização do seu conhecimento em Portugal. Para a realização deste
trabalho, começou-se por escolher um livro ilustrado de literatura infantil sobre
a filosofia da cultura chinesa, Tao. Em seguida, analisou-se o conteúdo da
obra e os significados filosóficos específicos, bem como as conotações
filosóficas que Lao Tzu deseja transmitir. Este estudo inclui a análise das
ilustrações e o seu contributo para a compreensão do conteúdo filosófico por
parte da criança e o seu significado na sociedade ocidental moderna, tendo em
vista a construção da mensagem. Além disso, o estudo também inclui as
apresentações do autor, da ilustradora e de Lao Tzu, bem como do taoísmo,
sem esquecer o contributo dos elementos da cultura tradicional chinesa na
literatura infantil de base filosófica.This dissertation aims to analyze the illustrated children's album Tao, text by
Manel Ollé and illustrations by Neus Caamaño, a Chinese-inspired work
recently published in Portugal. The purpose of this work is to study an example
of children's literature, published in a Portuguese context, inspired by Chinese
philosophy, contributing to the popularization of its knowledge in Portugal. To
carry out this work, we started by choosing an illustrated book of children's
literature about the philosophy of Chinese culture, Tao. Then, we intend to
analyze the content of the work and the specific philosophical meanings, as
well as the philosophical connotations that Laozi wishes to convey. This study
includes the analysis of the illustrations and their contribution to the child's
understanding of the philosophical content and its significance in modern
Western society, with a view to enlightening children. In addition, the study also
includes introductions of the author, the illustrator and Laozi, as well as Taoism,
not to mention the contribution of elements of traditional Chinese culture in
philosophically-based children's literature.Mestrado em Português Língua Estrangeira/Língua Segund
Introducing modeling, analysis, and control of three-phase electrical systems using geometric algebra

Permission from IEEE must be obtained for all other uses, in any current or future media, including reprinting/republishing this material for advertising or promotional purposes, creating new collective works, for resale or redistribution to servers or lists, or reuse of any copyrighted component of this work in other works.This article introduces a novel framework based on geometric algebra (GA) for the modeling, analysis, and control of three-phase electrical systems, with a focus on unbalanced scenarios. The proposed approach utilizes GA to represent these systems using simplified single-input/single-output (SISO) models, significantly reducing their mathematical complexity while maintaining accuracy. The framework introduces GA-valued transfer functions (GA-TFs), enabling the extension of well-established multivariable (MIMO) techniques, such as Youla-Kucera parameterization, into the GA domain as an illustrative example. This demonstrates the adaptability of classical tools within the new algebra. The validity and potential of the approach are showcased through numerical examples of balanced and unbalanced systems, as well as physical implementations in a laboratory setup. The results confirm that GA provides a robust and scalable foundation for simplifying the analysis and control of three-phase systems, paving the way for future theoretical and practical advancements.Received 13 June 2024; revised 16 September 2024, 9 December 2024, and 31 January 2025; accepted 8 March 2025.

An Overview of in Silico Methods for the Prediction of Ionizing Radiation Resistance in Bacteria
No full textInternational audienceIonizing-radiation-resistant bacteria (IRRB) could be used for biore-mediation of radioactive wastes and in the therapeutic industry. Limited computational works are available for the prediction of bacterial ionizing radiation resistance (IRR). In this chapter, we present some works that study the causes of the high resistance of IRRB to ionizing radiation. Then we focus on presenting in silico approaches that use protein sequences of bacteria in order to predict if an unknown bacterium belongs to IRRB or ionizing-radiation-sensitive bacteria (IRSB). These approaches formulate the problem of predicting bacterial IRR as a multiple instance learning (MIL) problem where bacteria represent the bags and * Corresponding Author: [email protected]. 2 Manel Zoghlami, Sabeur Aridhi, Mondher Maddouri et al. primary structure of basal DNA repair proteins of each bacterium represent the instances inside the bags. We also present a formulation of the problem of MIL in sequence data and explain how it could be used to solve the problem of IRR prediction in bacteria. A brief comparison of the presented approaches is provided
