description: Une abondante littérature décrit l'islam comme une religion une et monolithique et présente les musulmans comme une communauté unifiée au plan des croyances, des obligations cultuelles et des règles à observer. Mais, actuellement, certains chercheurs (M. Chebel, F. Mohamed-Chérif, F. Dassetto) tentent de dépasser cette représentation et privilégient une approche complexe et plurielle de l'islam. Les termes de diversité, pluralité ou islams au pluriel font justement référence à cette hétérogénéité au sein de la religion musulmane. Par ce travail de mémoire, nous nous intéressons à la manière dont on peut enseigner cet islam pluriel dans une classe de troisième année de maturité gymnasiale. Le but étant de montreraux élèves que l'islam ne peut être réduit aux fondements d'un seul courant, en l'occurrence le sunnisme orthodoxe, mais qu'il est diversifié dans sa réalité sociohistorique. Cet écrit se veut être une analyse critique d'une expérience d'enseignement menée sur l'islam pluriel pendant huit périodes. Il s'appuie, d'une part, sur les concepts spontanés des élèves sur l'islam collectés en début de séquence et, d'autre part, sur les réponses de l'évaluation certificative finale pratiquée en fin de cycle sur la religion musulmane. La confrontation entre les représentations des élèves et les résultats de l'évaluation doit permettre d'évaluer les modifications des savoirs des élèves et de mesurer la pertinence des tâches et activités proposées. De plus, ce travail interroge l'intérêt, les limites et les apories de cette séquence sur la pluralité en islam et cherche notamment à montrer les obstacles rencontrés et à proposer des remédiations dans le but d'améliorer l'apprentissage des élèves sur ce thème.

description: Let $(Γ,γ)$ be a crystallization of connected compact 3-manifold $M$ with $h$ boundary components. Let $\mathcal{G}(M)$ and $\mathit k (M)$ be the regular genus and gem-complexity of $M$ respectively, and let $\mathcal{G}(\partial M)$ be the regular genus of $\partial M$. We prove that $$\mathit k (M)\geq 3 (\mathcal{G}(M)+h-1) \geq 3 (\mathcal{G} (\partial M)+h-1).$$ These bounds for gem-complexity of $M$ are sharp for several 3-manifolds with boundary. Further, we show that if $\partial M$ is connected and $\mathit k (M)< 3 (\mathcal{G} (\partial M)+1)$ then $M$ is a handlebody. In particular, we prove that $\mathit k (M) =3 \mathcal{G} (\partial M)$ if $M$ is a handlebody and $\mathit k (M) \geq 3 (\mathcal{G} (\partial M)+1)$ if $M$ is not a handlebody. Further, we obtain several combinatorial properties for a crystallization of 3-manifolds with boundary.

description: Dans notre travail, nous avons comparé deux méthodes d’organisation et d’apprentissage des mots du vocabulaire français. Avec deux de nos classes, nous avons testé successivement une organisation alphabétique du vocabulaire avec un travail individuel à la maison puis une organisation thématique avec un travail multi-épisodique en classe afin que les élèves puissent s’approprier les mots. Notre hypothèse était qu’une organisation thématique couplée à de multiples rencontres des élèves avec les mots la semaine précédant le test favoriserait l’apprentissage. Pour formuler cette hypothèse nous nous sommes appuyés sur les recherches de Lieury en ce qui concerne la mémorisation et de Calaque et Bonnet pour le travail multi-épisodique du vocabulaire. L’expérience s’est déroulée en deux temps. Dans un premier temps, nos deux classes ont appris 120 mots en 6 vocabulaires, sur 6 semaines. L’une des classes avait des listes alphabétiques alors que l’autre avait des listes thématiques et travaillait le vocabulaire en classe. Puis, dans un second temps, les rôles ont été inversé avec une nouvelle série de 120 mots. Nous nous sommes efforcés de créer des listes de difficulté équivalente. Nous avons mis en place des tests de vocabulaire hebdomadaires ainsi que des pré-tests et des post-tests afin de vérifier leur progression. Nous avons ainsi pu mesurer et quantifier le nombre de nouveaux mots que chaque élève a retenus sur le long terme. Les résultats ont été surprenants!; une des deux classes a plus progressé avec la méthode alphabétique alors que l’autre a obtenu les résultats inverses. Différents facteurs peuvent expliquer ces différences, notamment la voie (VSG, VSB), la difficulté des listes, une plus grande familiarité des questions posées lors de la deuxième série. Nous en concluons qu’en l’absence de résultats convaincants en faveur d’une méthode et d’une organisation particulière, nous préférons intégrer le vocabulaire à d’autres éléments de l’enseignement du français, la lecture par exemple.

description: El objetivo de esta investigación fue evaluar dosis de nitrógeno y régimen hídrico sobre el crecimiento, producción y calidad de la cebolla. Para ello se evaluaron cuatro niveles de humedad aprovechable del suelo (25, 50, 75 y 100%) y cuatro dosis de fertilizante nitrogenado (100, 150, 200 y 250 Kg N ha-1 ). De la combinación de ambos factores se generaron 16 tratamientos y los resultados fueron los siguientes. Las variables evaluadas fueron parámetros e índices de crecimiento (Tasa Absoluta de Crecimiento (TAC), Tasa Relativa de Crecimiento (TRC) y Tasa de Asimilación Neta (TAN). En calidad física del bulbo (calibres, diámetros, número y grosor de catáfilas, color y firmeza). Calidad química (pH, acidez, oBrix y materia seca) y en calidad bioquímica (ácido ascórbico, ácido pirúvico y fenoles totales) actividad antioxidante (FRAP, DDPH y ABTS; además de la actividad antihemolítica o AAPH) y rendimiento por ha-1 . En poscosecha, calidad física y química de la cebolla por efecto de la eliminación de capas o catáfilas de la cebolla durante el mercadeo. Las tasas de crecimiento de la cebolla TAC y TRC, se incrementaron por efecto del aumento en el agua de riego y dosis de fertilizante nitrogenada. La interacción de ambos factores se presentó en el periodo de 100 a 130 ddt en TAC, mientras que en la TRC la interacción fue en los dos periodos evaluados (69 a 100 y de 100 a 130 ddt). La producción de materia seca por unidad de superficie (TAN), fue inversamente proporcional a las cantidades de agua y fertilizante.

description: We study integral points on the quadratic twists $\mathcal{E}_D:y^2=x^3-D^2x$ of the congruent number curve. We give upper bounds on the number of integral points in each coset of $2\mathcal{E}_D(\mathbb{Q})$ in $\mathcal{E}_D(\mathbb{Q})$ and show that their total is $\ll (3.8)^{\mathrm{rank} \mathcal{E}_D(\mathbb{Q})}$. We further show that the average number of non-torsion integral points in this family is bounded above by $2$. As an application we also deduce from our upper bounds that the system of simultaneous Pell equations $aX^2-bY^2=d$, $bY^2-cZ^2=d$ for pairwise coprime positive integers $a,b,c,d$, has at most $\ll (3.6)^{ω(abcd)}$ integer solutions.

description: Notre mémoire se concentre sur l’enseignement du contexte d’une oeuvre littéraire en langue étrangère. Il contient tout d’abord une partie théorique qui introduit la méthode CLIL. Celle-ci propose de baser l’enseignement d’une langue étrangère sur un contenu plutôt quesur la forme. Dans notre cas pratique, nous avons enseigné le contexte historique deQuicksand, l’oeuvre de Nella Larsen, auteure afro-américaine du début du XXème siècle.Premièrement, nous avons mis en pratique une séquence basée sur cette méthode CLIL, dans laquelle le contenu, la communication, la cognition et la culture sont des éléments essentiels. Cette méthode repose sur l’activité des étudiants, qui doivent remplir une tâche spécifique à l’aide de documents authentiques. Cette manière de procéder entraine la motivation des étudiants, notamment parce qu’ils participent à leur propre apprentissage. La séquence suivante était basée, au contraire, sur une approche frontale, où l’enseignante a fait une présentation de l’introduction et du premier chapitre du livre. Les étudiants ont également bénéficié de cette forme de travail car cette première analyse leur a montré ce qui était attendu d’eux lors de leurs futures présentations. Ceux-ci, par la suite, en groupe de 4 ou 5, ont reçu des instructions précises concernant les rôles spécifiques que chacun devaient remplir lors des présentations, afin d’éviter qu’ils ne se répètent et pour faciliter les travaux de groupe. C’est notamment grâce à ces présentations, à l’analyse des différents passages et des sources primaires, ainsi qu’aux questionnaires qu’ils ont rempli en début et en fin de séquence, qu’il nous a été possible d’évaluer notre séquence.

Rippling transition from electron-induced condensation of curvature field in graphene

description: A quantum field theory approach is applied to investigate the dynamics of flexural phonons in a metallic membrane like graphene, looking for the effects deriving from the strong interaction between the electronic excitations and elastic deformations. Relying on a self-consistent screening approximation to the phonon self-energy, we show that the theory has a critical point characterized by the vanishing of the effective bending rigidity of the membrane at low momentum. We also check that the instability in the sector of flexural phonons takes place without the development of an in-plane static distortion, which is avoided due to the significant reduction of the electron-phonon couplings for in-plane phonons at large momenta. Furthermore, we analyze the scaling properties of the many-body theory to identify the order parameter that opens up at the point of the transition. We find that the vanishing of the effective bending rigidity and the onset of a nonzero expectation value of the mean curvature are concurrent manifestations of the critical behavior. The results presented here imply that, even in the absence of tension, the theory has a critical point at which the flat geometry becomes an unstable configuration of the metallic membrane, with a condensation of the mean curvature field that may well reproduce the smooth distribution of ripples observed in free-standing graphene.

description: Isotropic functions of positions $\hat{\bf r}_1, \hat{\bf r}_2,\ldots, \hat{\bf r}_N$, i.e. functions invariant under simultaneous rotations of all the coordinates, are conveniently formed using spherical harmonics and Clebsch-Gordan coefficients. An orthonormal basis of such functions provides a formalism suitable for analyzing isotropic distributions such as those that arise in cosmology, for instance in the clustering of galaxies as revealed by large-scale structure surveys. The algebraic properties of the basis functions are conveniently expressed in terms of 6-$j$ and 9-$j$ symbols. The calculation of relations among the basis functions is facilitated by "Yutsis" diagrams for the addition and recoupling of angular momenta.

description: The goal of response theory, in each of its many statistical mechanical formulations, is to predict the perturbed response of a system from the knowledge of the unperturbed state and of the applied perturbation. A new recent angle on the problem focuses on providing a method to perform predictions of the change in one observable of the system by using the change in a second observable as a surrogate for the actual forcing. Such a viewpoint tries to address the very relevant problem of causal links within complex system when only incomplete information is available. We present here a method for quantifying and ranking the predictive ability of observables and use it to investigate the response of a paradigmatic spatially extended system, the Lorenz '96 model. We perturb locally the system and we then study to what extent a given local observable can predict the behaviour of a separate local observable. We show that this approach can reveal insights on the way a signal propagates inside the system. We also show that the procedure becomes more efficient if one considers multiple acting forcings and, correspondingly, multiple observables as predictors of the observable of interest.

description: We present a novel algorithm to detect double nuclei galaxies (DNG) called GOTHIC (Graph BOosted iterated HIll Climbing) - that detects whether a given image of a galaxy has two or more closely separated nuclei. Our aim is to detect samples of dual or multiple active galactic nuclei (AGN) in galaxies. Although galaxy mergers are common, the detection of dual AGN is rare. Their detection is very important as they help us understand the formation of supermassive black hole (SMBH) binaries, SMBH growth and AGN feedback effects in multiple nuclei systems. There is thus a need for an algorithm to do a systematic survey of existing imaging data for the discovery of DNGs and dual AGN. We have tested GOTHIC on a known sample of DNGs and subsequently applied it to a sample of a million SDSS DR16 galaxies lying in the redshift range of 0 to 0.75 approximately, and have available spectroscopic data. We have detected 159 dual AGN in this sample, of which 2 are triple AGN systems. Our results show that dual AGN are not common, and triple AGN even rarer. The color (u-r) magnitude plots of the DNGs indicate that star formation is quenched as the nuclei come closer and as the AGN fraction increases. The quenching is especially prominent for dual/triple AGN galaxies that lie in the extreme end of the red sequence.

description: Meta-conformal invariance is a novel class of dynamical symmetries, with dynamical exponent $z=1$, and distinct from the standard ortho-conformal invariance. The meta-conformal Ward identities can be directly read off from the Lie algebra generators, but this procedure implicitly assumes that the co-variant correlators should depend holomorphically on time- and space coordinates. Furthermore, this assumption implies un-physical singularities in the co-variant correlators. A careful reformulation of the global meta-conformal Ward identities in a dualised space, combined with a regularity postulate, leads to bounded and regular expressions for the co-variant two-point functions, both in $d=1$ and $d=2$ spatial dimensions.

description: Glioblastoma (GBM) is the most common type of primary brain tumor. Patients with GBM have poor survival outcomes. Isolated components of Momordica charantia have anticancer effects. However, the bioactivity of M. charantia extracts against GBM remains unknown. We tested four major extracts of M. charantia and found that momordicine I reduced glioma cell viability without serious cytotoxic effects on astrocytes. Momordicine I suppressed glioma cell colony formation, proliferation, migration, and invasion. Momordicine I also induced apoptosis, intracellular reactive oxygen species (ROS) production, and senescence in glioma cells. Moreover, momordicine I decreased the oxidative phosphorylation capacity of glioma cells and inhibited tumor sphere formation in temozolomide (TMZ)-resistant GBM cells. We further explored whether the antiglioma effect of momordicine I may be related to cell cycle modulation and DLGPA5 expression. Our results indicate that the cytotoxic effect of momordicine I on glioma cells suggests its potential therapeutic application to GBM treatment.

Linear Stability of solitary waves for the isothermal Euler-Poisson system

Subjects: subject: Analysis of PDEs (math.AP)

description: We study the asymptotic linear stability of a two-parameter family of solitary waves for the isothermal Euler-Poisson system. When the linearized equations about the solitary waves are considered, the associated eigenvalue problem in $L^2$ space has a zero eigenvalue embedded in the neutral spectrum, i.e., there is no spectral gap. To resolve this issue, use is made of an exponentially weighted $L^2$ norm so that the essential spectrum is strictly shifted into the left-half plane, and this is closely related to the fact that solitary waves exist in the super-ion-sonic regime. Furthermore, in a certain long-wavelength scaling, we show that the Evans function for the Euler-Poisson system converges to that for the Korteweg-de Vries (KdV) equation as an amplitude parameter tends to zero, from which we deduce that the origin is the only eigenvalue on its natural domain with algebraic multiplicity two. We also show that the solitary waves are spectrally stable in $L^2$ space. Moreover, we discuss (in)stability of large amplitude solitary waves.

description: La mia tesi si propone di indagare le implicazioni teoretiche del ricorso al dispositivo concettuale del paradosso in una selezione di autori quattro-cinquecenteschi: Leon Battista Alberti, Giovanni Pico della Mirandola, Erasmo da Rotterdam e Ortensio Lando. Il dato storico dal quale la ricerca prende le mosse riguarda l’elevata incidenza di opere paradossali che videro la luce nei secoli in oggetto, ispirate, per la maggior parte, dalla fortunata riscoperta dell’antico genere sofistico dei ἐγκώ ι e dall’accentuata ammirazione degli umanisti per lo stile serio-ludico di Luciano di Samosata. A partire da un’analisi della ricezione quattro-cinquecentesca di questo peculiare artificio retorico, il lavoro si propone di indagare se e come quest’ultimo abbia potuto travalicare la mera dimensione dell’exercitatio ludica, rivestendosi di specifiche connotazioni polemiche, eversive o euristiche legate alle potenzialità teoretiche che contraddistinguono il concetto stesso di paradosso. Dall’analisi condotta emerge quanto frequente, capillare e diversificato fosse il ricorso al paradosso nelle opere prese in esame e viene evidenziato il valore filosofico di un dispositivo concettuale in grado di dischiudere una via di accesso alla verità attraverso lo smascheramento della menzogna, la messa in discussione della doxa, lo stimolo nella prosecuzione della ricerca e il vaglio di alternative situate al di fuori delle logiche convenzionali.

description: My thesis is focused on assessing the theoretical value of paradox in Renaissance philosophy, starting from the analysis of Latin and vernacular texts composed by Leon Battista Alberti, Giovanni Pico della Mirandola, Erasmo da Rotterdam and Ortensio Lando. The research is historically justified by the wide dissemination of paradoxical works in the XV and XVI centuries, due to the fortunate rediscovery of the ancient sophistical genre of ἐγκώι and to the high consideration humanists had for Luciano of Samosata’s playful, and yet edifying, writing-style. The purpose of the thesis is then to investigate whether such paradoxical works could represent something deeper than a simple jeu d’esprit, assuming subversive or defiant meanings as the very concept of paradox may lead to suggest. The results of the analysis point out how varied and widespread the use of paradox was in the Renaissance, employed as a conceptual tool able to allow philosophical reflection through unconventional channels, such as the uncovering of falsehood and the critical question of common opinion.

description: We examine the performance of standard PMS stellar evolution models against the accurately measured properties of a benchmark sample of 26 PMS stars in 13 EB systems. We provide a definitive compilation of all fundamental properties for the EBs. We also provide a definitive compilation of the various PMS model sets. In the H-R diagram, the masses inferred for the individual stars by the models are accurate to better than 10% above 1 Msun, but below 1 Msun they are discrepant by 50-100%. We find evidence that the failure of the models to match the data is linked to the triples in the EB sample; at least half of the EBs possess tertiary companions. Excluding the triples, the models reproduce the stellar masses to better than ~10% in the H-R diagram, down to 0.5 Msun, below which the current sample is fully contaminated by tertiaries. We consider several mechanisms by which a tertiary might cause changes in the EB properties and thus corrupt the agreement with stellar model predictions. We show that the energies of the tertiary orbits are comparable to that needed to potentially explain the scatter in the EB properties through injection of heat, perhaps involving tidal interaction. It seems from the evidence at hand that this mechanism, however it operates in detail, has more influence on the surface properties of the stars than on their internal structure, as the lithium abundances are broadly in good agreement with model predictions. The EBs that are members of young clusters appear individually coeval to within 20%, but collectively show an apparent age spread of ~50%, suggesting true age spreads in young clusters. However, this apparent spread in the EB ages may also be the result of scatter in the EB properties induced by tertiaries. [Abridged]

description: Asynchronous and parallel implementation of standard reinforcement learning (RL) algorithms is a key enabler of the tremendous success of modern RL. Among many asynchronous RL algorithms, arguably the most popular and effective one is the asynchronous advantage actor-critic (A3C) algorithm. Although A3C is becoming the workhorse of RL, its theoretical properties are still not well-understood, including its non-asymptotic analysis and the performance gain of parallelism (a.k.a. linear speedup). This paper revisits the A3C algorithm and establishes its non-asymptotic convergence guarantees. Under both i.i.d. and Markovian sampling, we establish the local convergence guarantee for A3C in the general policy approximation case and the global convergence guarantee in softmax policy parameterization. Under i.i.d. sampling, A3C obtains sample complexity of $\mathcal{O}(ε^{-2.5}/N)$ per worker to achieve $ε$ accuracy, where $N$ is the number of workers. Compared to the best-known sample complexity of $\mathcal{O}(ε^{-2.5})$ for two-timescale AC, A3C achieves \emph{linear speedup}, which justifies the advantage of parallelism and asynchrony in AC algorithms theoretically for the first time. Numerical tests on synthetic environment, OpenAI Gym environments and Atari games have been provided to verify our theoretical analysis.
title: Understanding the role of language in integration journeys: ESOL from refugees' perspectives
Creators: name: Abdelghany, Sawsan
Publisher: name: University of Glasgow

description: This thesis focuses on refugees and asylum seekers’ needs in the context of learning English, and how language acts as a facilitator to their integration process. Drawing on an ethnographic research approach across Scotland – which included interviewing New Scots and ESOL practitioners and attending a variety of language classes for asylum seekers and refugees – the thesis presents an in-depth account of refugee integration and language in the Scottish context. In addition, the thesis draws on my own experience as a refugee in Scotland, which has assisted the research process. The research is timely as the Scottish Government is in the process of developing a new iteration of the New Scots Refugee Integration Strategy and reviewing ESOL provision in Scotland. The thesis presents key research findings and argues that the current ESOL provision available to New Scots does not always meet their learning needs, as they have different experiences and circumstances from other language learners. The thesis identifies specific needs as well as barriers that New Scots encounter and argues for innovative approaches in ESOL teaching to be adopted more-widely, such as an ecological multilingual approach, and a trauma informed approach for dealing with refugee learners. Indeed, participants in the research believed that contextual learning not only improves New Scots’ language acquisition but also supports better integration with their local community. Policy recommendations are included in the conclusion of the thesis, with the hope that these will assist New Scots in the future.

description: We study the local indistinguishability problem of quantum states. By introducing an easily calculated quantity, non-commutativity, we present an criterion which is both necessary and sufficient for the local indistinguishability of a complete set of pure orthogonal product states. A constructive distinguishing procedure to obtain the concrete local measurements and classical communications is given. The non-commutativity of ensembles can be also used to characterize the quantumness for classical-quantum or quantum-classical correlated states.

description: Weighted Logic is a powerful tool for the specification of calculations over semirings that depend on qualitative information. Using a novel combination of Weighted Logic and Here-and-There (HT) Logic, in which this dependence is based on intuitionistic grounds, we introduce Answer Set Programming with Algebraic Constraints (ASP(AC)), where rules may contain constraints that compare semiring values to weighted formula evaluations. Such constraints provide streamlined access to a manifold of constructs available in ASP, like aggregates, choice constraints, and arithmetic operators. They extend some of them and provide a generic framework for defining programs with algebraic computation, which can be fruitfully used e.g. for provenance semantics of datalog programs. While undecidable in general, expressive fragments of ASP(AC) can be exploited for effective problem-solving in a rich framework. This work is under consideration for acceptance in Theory and Practice of Logic Programming.

description: A high precision and high resolution time-to-digital converter (TDC) implemented in a 40 nm fabrication process Virtex-6 FPGA is presented in this paper. The multi-chain measurements averaging architecture is used to overcome the resolution limitation determined by intrinsic cell delay of the plain single tapped-delay chain. The resolution and precision are both improved with this architecture. In such a TDC, the input signal is connected to multiple tapped-delay chains simultaneously (the chain number is M), and there is a fixed delay cell between every two adjacent chains. Each tapped-delay chain is just a plain TDC and should generate a TDC time for a hit input signal, so totally M TDC time values should be got for a hit signal. After averaging, the final TDC time is obtained. A TDC with 3 ps resolution (i.e. bin size) and 6.5 ps precision (i.e. RMS) has been implemented using 8 parallel tapped-delay chains. Meanwhile the plain TDC with single tapped-delay chain yields 24 ps resolution and 18 ps precision.

Exact WKB and the quantum Seiberg-Witten curve for 4d $N=2$ pure $SU(3)$ Yang-Mills, Part I: Abelianization

description: We investigate the exact WKB method for the quantum Seiberg-Witten curve of 4d $N=2$ pure $SU(3)$ Yang-Mills, in the language of abelianization. The relevant differential equation is a third-order equation on $\mathbb{CP}^1$ with two irregular singularities. We employ the exact WKB method to study solutions to such a third-order equation and the associated Stokes phenomena. We also investigate the exact quantization condition for a certain spectral problem. Moreover, exact WKB analysis leads us to consider new Darboux coordinates on a moduli space of flat SL(3,$\mathbb{C}$)-connections. In particular, in the weak coupling region we encounter coordinates of higher length-twist type generalizing Fenchel-Nielsen coordinates. The Darboux coordinates are conjectured to admit asymptotic expansions given by the formal quantum periods series; we perform numerical analysis supporting this conjecture.

description: Dans notre mémoire professionnel, nous nous sommes intéressées au travail hors classe des élèves. Plus précisément, nous souhaitions analyser les transactions cognitives qui relient le cadre institutionnel scolaire avec un milieu peu institutionnalisé. Notre question de recherche était alors la suivante : « Comment s’opère le transfert cognitif de l’élève de la classe au travail hors classe ? » Nous avons également émis deux hypothèses : Hypothèse 1 : Les élèves réputés bons disposent d’un système cognitif qui arrive à faire le lien entre l’école et le travail hors classe. Les élèves réputés faibles n’y arrivent pas. Hypothèse 2 : L’enfant est plus motivé par d’autres acteurs pour faire le travail hors classe que par une réelle volonté d’apprentissage. Afin de récolter les données à analyser, nous avons fait des entretiens semi-directifs avec des questions formulées selon la méthode d’entretien dite « d’explicitation ». Les six élèves de deux classes différentes du CYT ont été choisis en fonction de leurs notes en Histoire. Les données des entretiens retranscrites ont ensuite été catégorisées par thèmes selon notre question de recherche et nos hypothèses. Puis, nous avons tiré des conclusions pour chaque thème. Suite à l’analyse de nos entretiens, notre première hypothèse a été confirmée. Les résultats par rapport à la deuxième hypothèse sont quant à eux plus nuancés. Tous les élèves interviewés semblent être influencés par des acteurs externes lors de la réalisation de leur travail hors classe. Cependant, pour ce qui est de leur motivation face aux devoirs, les élèves dits « bons » semblent être plus tournés vers une logique de l’apprentissage qui fait qu’ils ne font pas uniquement leurs devoirs pour faire plaisir à leurs parents ou à l’enseignant.

description: El propósito de este trabajo es examinar la intervención didáctica del profesor de italiano al corregir la producción oral, mediante el análisis y tipificación de errores, así como analizar la percepción de docentes y alumnos acerca del error y su corrección. Se hicieron observaciones en el aula a docentes de italiano, lo cual permitió compilar un corpus discursivo que condujo a la realización de una matriz de datos donde se analizaron los errores de acuerdo con la tipología etiológica del error de Corder. Asimismo, se llevaron a cabo entrevistas a seis docentes y diez alumnos de italiano donde se obtuvieron datos que develan que los participantes muestran una apertura ante el error y su corrección, sin embargo, se destaca que la formación profesional de los maestros influye en su percepción y la manera de intervenir en el aula. Las estrategias de corrección que prevalecen en las aulas de italiano son, principalmente, la corrección explícita, seguido de la corrección implícita, petición de clarificación y elicitación. Se desarrolló un modelo de sistematización del proceso error-corrección-aprendizaje, a partir de los datos analizados, donde se muestra cuál es el mejor momento para corregir, qué tipo de errores y con qué estrategia de corrección. Se considera que desde la formación inicial docente se deberían abordar temas que conciernen al error y su corrección, así como llevarlos a reflexionar para aprender de sus propias experiencias.

description: Measures of phylogenetic balance, such as the Colless and Sackin indices, play an important role in phylogenetics. Unfortunately, these indices are specifically designed for phylogenetic trees, and do not extend naturally to phylogenetic networks (which are increasingly used to describe reticulate evolution). This led us to consider a lesser-known balance index, whose definition is based on a probabilistic interpretation that is equally applicable to trees and to networks. This index, known as the $B_2$ index, was first proposed by Shao and Sokal in 1990. Surprisingly, it does not seem to have been studied mathematically since. Likewise, it is used only sporadically in the biological literature, where it tends to be viewed as arcane. In this paper, we study mathematical properties of $B_2$ such as its expectation and variance under the most common models of random trees and its extremal values over various classes of phylogenetic networks. We also assess its relevance in biological applications, and find it to be comparable to that of the Colless and Sackin indices. Altogether, our results call for a reevaluation of the status of this somewhat forgotten measure of phylogenetic balance.

description: The electronic and magnetic properties of the graphene/Eu/Ni(111) intercalation-like system are studied in the framework of the GGA+U approach with dispersive interactions taken into account. Intercalation of monoatomic Eu layer underneath graphene on Ni(111) leads to the drastic changes of the electronic structure of graphene compared to free-standing graphene as well as graphene/Ni(111). The strong influence of the spin-polarised Eu 4f states, crossing the graphene-derived $π$ states, on magnetic properties of graphene and on spin-filtering properties of the graphene/Eu/Ni(111) trilayer is discussed.

Soutien social comparé d'enseignants et de managers d'une entreprise dans des situations d'épuisement (burnout)

description: Ce mémoire s’inscrit dans les recherches sur le burnout et plus particulièrement l’étude du soutien social considéré comme le facteur de protection le plus efficace. Les recherches existantes sont généralement ciblées sur les professions basées sur les relations d’aide (enseignants, médecins, psychologues). Cette recherche a pour but d’élargir le champ d’étude en effectuant une comparaison entre managers d’une entreprise et enseignants. L’étude portera sur leurs représentations sur le burnout et plus particulièrement le type de soutien social sollicité. Ma revue de littérature a fait ressortir deux dimensions du soutien social (émotionnel /instrumental) et deux catégories de facteur d’épuisement (professionnel / personnel). Le résultat de mes neuf entretiens sur ces quatre facteurs a fait apparaître des différences entre managers et enseignants. Les managers seraient plutôt demandeurs de soutien instrumental pour faire face à un épuisement de type professionnel. Les enseignants seraient plutôt demandeurs de soutien émotionnel accompagné de soutien instrumental pour faire face principalement à un épuisement de type personnel. J’ai donc formulé l’hypothèse que les managers seraient davantage préoccupés par la recherche de solutions professionnelles puisqu’ils demandent un soutien instrumental alors que les enseignants auraient plus de difficultés à distinguer types d’épuisement et types de soutien social. On peut donc conclure que les spécificités de la profession ont une incidence sur les représentations du burnout et la sollicitation de recherche de soutien social. Un autre résultat commun aux neuf professionnels est l’absence de perception de la dimension de la déshumanisation dans la relation avec les destinataires de leurs services (élèves et clients) comme conséquence potentielle d’un burnout. Ce résultat confirme la nécessité d’informer les professionnels sur les conséquences du burnout, non seulement sur leur propre personne, mais également les personnes à qui ils fournissent un service. Ce travail offre des perspectives de recherches plus approfondies sur les corps de métiers peu étudiés à propos du burnout.
