description: Travailler le rapport au savoir des élèves : analyse de la perception de trois situations d’apprentissage en anglais par des élèves de première année d’école de Maturité. Pourquoi certains élèves réussissent-ils mieux que d’autres à l’école ou dans leurs études ? Les parcours scolaires différenciés et différenciateurs sont-ils inhérents aux élèves eux- mêmes, que ce soit par rapport à leurs facultés intellectuelles ou leur origine sociale, ou l’école est-elle en partie responsable de ceux-ci ? Dans ce dernier cas, l’enseignant peut-il trouver des raisons de ces différenciations inter-élèves dans sa propre pratique et, si oui, peut- il l’améliorer de manière à aider les élèves et les conduire vers la réussite scolaire ? S’appuyant sur les recherches en sciences de l’éducation menées depuis plusieurs années par l’équipe ESCOL à Paris, qui a notamment développé la notion de rapport au savoir des élèves en vue de comprendre ce qui était à l’origine des inégalités scolaires, et qui a ainsi démontré que l’école et les pratiques enseignantes faisaient bien partie du problème, le but du présent travail est d’essayer de saisir ce qui, dans ma pratique et les situations d’apprentissage mises en place dans ma classe d’anglais, peut être source de difficultés pour les élèves. Dans cette perspective, quatre élèves de première année de gymnase (voie maturité) ont été invités à remplir un questionnaire général visant à connaître leur expérience langagière ainsi que leurs attentes et croyances concernant l’apprentissage de l’anglais à l’école, puis ont été interrogés séparément sur trois tâches typiques de l’enseignement de l’anglais, en cours de tâche. Les données ainsi récoltées ont ensuite été analysées en vue de cerner si les élèves percevaient bien les enjeux des différentes tâches et ce qu’ils étaient censés y apprendre, ou si malentendu il y avait. Enfin, des pistes ont été proposées afin de remédier aux problèmes rencontrés. Les résultats des discussions avec les élèves sont étonnants et éclairent bien les difficultés empêchant ces derniers à s’approprier les savoirs de manière optimale. En cela, ils représentent une mine d’informations et un exemple à suivre pour tout enseignant qui désire participer de la réussite scolaire de ses élèves en comprenant ce qui, dans sa pratique, est susceptible de créer des obstacles à leurs apprentissages.

description: We study closed ancient solutions to gradient flows of elliptic functionals in Riemannian manifolds, including mean curvature flow and harmonic map heat flow. Our work has various consequences. In all dimensions and codimensions, we classify ancient mean curvature flows in S^n with low area: they are steady or shrinking equatorial spheres. In the mean curvature flow case in S^3, we classify ancient flows with more relaxed area bounds: they are steady or shrinking equators or Clifford tori. In the embedded curve shortening case in S^2, we completely classify ancient flows of bounded length: they are steady or shrinking circles.

description: This paper highlights the design philosophy and architecture of the Health Guardian, a platform developed by the IBM Digital Health team to accelerate discoveries of new digital biomarkers and development of digital health technologies. The Health Guardian allows for rapid translation of artificial intelligence (AI) research into cloud-based microservices that can be tested with data from clinical cohorts to understand disease and enable early prevention. The platform can be connected to mobile applications, wearables, or Internet of things (IoT) devices to collect health-related data into a secure database. When the analytics are created, the researchers can containerize and deploy their code on the cloud using pre-defined templates, and validate the models using the data collected from one or more sensing devices. The Health Guardian platform currently supports time-series, text, audio, and video inputs with 70+ analytic capabilities and is used for non-commercial scientific research. We provide an example of the Alzheimer's disease (AD) assessment microservice which uses AI methods to extract linguistic features from audio recordings to evaluate an individual's mini-mental state, the likelihood of having AD, and to predict the onset of AD before turning the age of 85. Today, IBM research teams across the globe use the Health Guardian internally as a test bed for early-stage research ideas, and externally with collaborators to support and enhance AI model development and clinical study efforts.

description: The aim of research is to obtain a mathematical description of the effect of the content of chemical elements in cast iron on its mechanical properties and the subsequent optimization of the chemical composition, allowing to identify possible production reserves. The presence of such reserves is associated with the possibility of selecting such a number of ferroalloys that would provide the best indicators of mechanical properties while reducing the consumption rates of expensive charge materials. The object of research is cast iron of serial heats for the manufacture of shaped castings for automobile and road vehicles. The intellectual methodology for the study of large systems (IMSLS) is chosen as the research method, the application of which is justified by the following arguments: - possibility of formalizing the statement of the problem – building dependencies of the "composition - properties" type, - information for building a mathematical model is presented in the form of a data table of a passive industrial experiment, - objectivity of the resulting dependencies. The procedure for using IMSLS for processing experimental data of serial industrial heats is described. The solution of two specific practical problems of modeling is presented: obtaining a mathematical model for synthesizing the optimal composition of cast iron in terms of ultimate strength and obtaining a mathematical model for synthesizing the optimal composition of cast iron in terms of a generalized quality indicator. It is shown that the use of the obtained models based on the IMSLS use makes it possible to reveal which of the elements of the chemical composition have a more significant effect on graphitization, and which ones – on the formation of the synthetic cast iron matrix. The results obtained can be used in real industrial production to select technological solutions that allow to control the formation of the microstructure of cast iron. This can be done, for example, by selecting the components of the charge, choosing the optimal or rational technological modes of complex alloying and modification, which provide the best indicators of its mechanical properties during the smelting of cast iron.

description: Ce mémoire s’intéresse à la question de savoir quel est le rôle de la littérature en filière maturité et quels sont les objectifs d’apprentissage avec cet objet de cours. Pour s’approcher de cette question, j’ai premièrement illustré une unité d’enseignement au sujet de Der Schachspieler de Friedrich Dürrenmatt. Cette unité visait l’introduction de l’analyse d’un texte littéraire. Ayant observé une difficulté chez les élèves à l’approche d’une analyse de texte, j’ai opté d’abord pour un travail analytique sur les illustrations de Der Schachspieler. Le caractère non-langagier du matériel visuel du livre était considéré comme favorable dans ce contexte, car les élèves étaient confrontés à la difficulté de s’exprimer dans une langue étrangère sur un document rédigé dans cette même langue. En outre, j’ai défini avec les élèves quatre phases à parcourir durant une analyse d’illustrations ou une analyse de texte. Ces quatre phases étaient censées, d’une part, structurer l’approche du médium et, d’autre part, graduer le processus de réception, en commençant avec une perspective neutre et en terminant avec une perspective personnelle qui est celle du commentaire. Les quatre phases d’analyse étaient ensuite appliquées à l’histoire Der Schachspieler. La question initiale est, dans un deuxième temps, considérée sous l’angle de la discussion théorique. De l’aperçu historique émane l’idée que le rôle de la littérature en cours de langue étrangère a regagné de l’importance depuis les années 80. Le changement de paradigme vers l’approche communicative et ensuite l’approche actionnelle a cependant mis en question la place de la littérature en cours de langue étrangère. L’étude de plusieurs publications a illustré que de nombreux didacticiens voyaient les valeurs esthétiques et émotionnelles de la littérature mises en danger par la vague de standardisation et l’alignement au CECR. L’analyse de pratique dans la dernière partie du mémoire se portait sur la justification personnelle de mon choix de la littérature comme objet de mes cours au Gymnase. Mise à part des bénéfices au niveau linguistique, la valeur esthétique de la littérature a été soulignée. En outre, le déchiffrage de la structure de la langue étrangère a été considéré comme élément fondamental dans la formation d’élèves critiques dans le cadre du Gymnase.

description: Different from reinforced concrete slabs, composite slabs appear more complicated tensile membrane action (TMA) in fire conditions. An improved TMA model is proposed to accurately determine the fire resistance of composite slabs exposed to ISO834 fire. It is assumed that the fracture of steel reinforcement in the long span is the governing failure mode of composite slabs at elevated temperatures. The slab is divided into four concrete rigid plates and one elliptic reinforcement net at centre considering TMA, and the contribution of rotation of concrete rigid plates on the deflection in short-span is taken into account. It is found that the improved model has a great prediction of the mid-span deflection and fire resistance. Meanwhile, coupling thermo-mechanical finite element analyses are carried out to simulate the TMA response of composite slabs at elevated temperatures. The results show that the failure mode is the fracture of the reinforcement in long span, the same as the assumption of the improved model.

description: We reconstruct the all-genus Fan-Jarvis-Ruan-Witten invariants of a Fermat cubic Landau-Ginzburg space $(x_1^3+x_2^3+x_3^3: [\mathbb{C}^3/ \mathboldμ_3]\to \mathbb{C})$ from genus-one primary invariants, using tautological relations and axioms of Cohomological Field Theories. These genus-one invariants satisfy a Chazy equation by the Belorousski-Pandharipande relation. They are completely determined by a single genus-one invariant, which can be obtained from cosection localization and intersection theory on moduli of three spin curves. We solve an all-genus Landau-Ginzburg/Calabi-Yau Correspondence Conjecture for the Fermat cubic Landau-Ginzburg space using Cayley transformation on quasi-modular forms. This transformation relates two non-semisimple CohFT theories: the Fan-Jarvis-Ruan-Witten theory of the Fermat cubic polynomial and the Gromov-Witten theory of the Fermat cubic curve. As a consequence, Fan-Jarvis-Ruan-Witten invariants at any genus can be computed using Gromov-Witten invariants of the elliptic curve. They also satisfy nice structures including holomorphic anomaly equations and Virasoro constraints.

description: This article examines the dependence of the European Union's solar and wind industries on Chinese supply of five critical raw materials: tellurium, gallium, indium, and the rare earths neodymium and dysprosium. Based partly on interviews with experts, this study reviews China's industrial policies that shape the supply of these materials abroad. We also assess the short- and long-term strategies of the European Union and European solar and wind industries to ameliorate potential supply bottlenecks. While these strategies adequately address short-term challenges, we find they pose several long-term risks, such as increasing the dependence on China and hampering European competitiveness in global markets. There is also divergence in the extent to which these two industries are vulnerable to supply bottlenecks and price volatility; because more options are open to them, European solar manufacturers are less exposed to these risks than their counterparts in the offshore wind sector.

description: This study analyses impacts of China’s outward foreign direct investment on host country policies and on the bilateral relationship with China by unravelling European and Chinese perceptions. We compare how China’s takeover of German robotics manufacturer KUKA AG and the investment into nuclear power project Hinkley Point C in the UK were perceived amongst European societal, economic and political stakeholders. Based on media articles, companies’ statements, political statements and interviews in China and the UK, we argue that China’s investments in Europe lead to threat perceptions amongst host country stakeholders and fuel debates on whether and how to regulate deals that could harm security and technology interests. While rising threat perceptions have already altered FDI policies in the UK, the German case inherits the potential to alter economic policies.
Infiltrating a thin or single layer opal with an atomic vapour: sub-doppler signals and crystal optics

description: Artificial thin glass opals can be infiltrated with a resonant alkali-metal vapour, providing novel types of hybrid systems. The reflection at the interface between the substrate and the opal yields a resonant signal, which exhibits sub-Doppler structures in linear spectroscopy for a range of oblique incidences. This result is suspected to originate in an effect of the three-dimensional confinement of the vapour in the opal interstices. It is here extended to a situation where the opal is limited to a few or even a single layer opal film, which is a kind of bidimensional grating. We have developed a flexible one-dimensional layered optical model, well suited for a Langmuir-Blodgett opal. Once extended to the case of a resonant infiltration, the model reproduces quick variations of the lineshape with incidence angle or polarization. Alternately, for an opal limited to a single layer of identical spheres, a three-dimensional numerical calculation was developed. It predicts crystalline anisotropy, which is demonstrated through diffraction on an empty opal made of a single-layer of polystyrene spheres.

description: The field of computer vision has greatly matured in the past decade, and many of the methods and techniques can be useful for astronomical applications. One example is in searching large imaging surveys for objects of interest, especially when it is difficult to specify the characteristics of the objects being searched for. We have developed a method using contour finding and convolution neural networks (CNNs) to search for Infrared Dark Clouds (IRDCs) in the Spitzer Galactic plane survey data. IRDCs can vary in size, shape, orientation, and optical depth, and are often located near regions with complex emission from molecular clouds and star formation, which can make the IRDCs difficult to reliably identify. False positives can occur in regions where emission is absent, rather than from a foreground IRDC. The contour finding algorithm we implemented found most closed figures in the mosaic and we developed rules to filter out some of the false positive before allowing the CNNs to analyze them. The method was applied to the Spitzer data in the Galactic plane surveys, and we have constructed a catalog of IRDCs which includes additional parts of the Galactic plane that were not included in earlier surveys.

description: Kronheimer-Mrowka recently proved that the Dehn twist along a 3-sphere in the neck of $K3\#K3$ is not smoothly isotopic to the identity. This provides a new example of self-diffeomorphisms on 4-manifolds that are isotopic to the identity in the topological category but not smoothly so. (The first such examples were given by Ruberman.) In this paper, we use the Pin(2)-equivariant Bauer-Furuta invariant to show that this Dehn twist is not smoothly isotopic to the identity even after a single stabilization (connected summing with the identity map on $S^{2}\times S^{2}$). This gives the first example of exotic phenomena on simply connected smooth 4-manifolds that do not disappear after a single stabilization.

description: Ce travail porte sur l'utilisation et les représentation qu'on les enfants d'Internet et du téléphone portable. 18 pré-adolescents âgés de 10 et 11 ans ont été interrogés en classe à l'aide d'un questionnaire. Celui-ci est axé sur la manière d'utiliser Internet à la maison ainsi que sur le temps qu'ils y passent. Les différents dangers, le contrôle parental, les téléphones portables (qui le paie, la communication par message, les messages violents/blessants) ainsi que les perceptions par opposition à la réalité sur ces différents points sont également traités. Les résultats de notre recherche montrent que la majorité des élèves semble avoir entendu parler des dangers d'Internet par la famille. Ils semblent aussi passer plus de temps sur Internet la semaine que le weekend. Peu d'enfants disent être contrôlés par leurs parents lorsqu'ils vont sur Internet. Dans la classe 13 élèves sur 18 possèdent un téléphone portable. De manière générale, la facture téléphonique des élèves coûte entre 15.- et 30.- par mois, sauf pour un élève qui dit dépasser les 50.- par mois. Les enfants ont tendance à sous-estimer le coût de la facture téléphonique de leurs camarades. Ils semblent ne pas encore être touchés par l'attaque de messages ou de photos choquants ou blessants (ni sur Internet, ni sur le téléphone portable). En ce qui concerne les perceptions des élèves, dans certains cas ils semblent être assez proche de la réalité, comme par exemple dans l'utilisation d'Internet par leurs pairs dans certains domaines (chat, e-mail). Alors que, en ce qui concerne leur perception par rapport à facebook, ils surestiment l'utilisation que leurs pairs en font. Un autre exemple : les recherches personnelles sur Internet sont sous-estimées par rapport à la réalité. Cette étude, malgré les limites (nombre de sujets), permet d'avoir une première estimation sur l'utilisation des médias chez les plus jeunes. Une discussion est effectuée par rapport à d'éventuelles mesures préventives dans ce domaine.

China’s Outward Investment under “Hierarchical Steering” and “Grassroots Internationalisation”

subject: Outward FDI

subject: 320

description: The debate on China’s outward investment largely focuses on its determinants: enterprises’ interests and the role of the Chinese state. However, what these approaches often tend to ignore is that China is not a unitary outward-investing country. Instead, some Chinese provinces have been able to become the major drivers of China’s outward investment and the investment outflows of these provinces emerge out of locality-unique contexts. This research looks at path-dependencies and encapsulates different provincial internationalisation trajectories to advance our understanding of China’s overseas engagement. In investigating two “success stories” of provinces with high investment outflows, Jiangsu and Zhejiang provinces, two different forms of provincial internationalisation based on locality-unique political, economic, and social conditions are detailed. While investment outflows from both provinces were facilitated by cultures of local manufacturing industries, their internationalisation paths are conceptualised as either “hierarchical steering” or “grassroots internationalisation.”

description: Les élèves de l'enseignement spécialisé qui ont de grandes difficultés d'apprentissages et/ou des troubles de la personnalité et du comportement peuvent-ils bénéficier d'une intervention métacognitive en classe et progresser dans leurs apprentissages ? Est-il possible d'appliquer un enseignement stratégique dans une classe de l'enseignement spécialisé et comment une enseignante spécialisée peut-elle intégrer ce type d'enseignement dans sa pratique afin d'utiliser ce modèle pédagogique pour favoriser ainsi les apprentissages et leur transfert ? Ce mémoire professionnel présente une recherche sur les effets d'une intervention métacognitive dans une classe de l'enseignement spécialisé. C'est le résultat d'un travail réalisé dans le cadre de l'enseignement du français "Expression textuelle" basé sur l'enseignement stratégique qui est un modèle pédagogique issu de la psychologie cognitive. La réflexion métacognitive n'est pas un comportement qui est spontané et qui est utilisé par tous les élèves. Cette réflexion métacognitive se met en pace chez les élèves au cours de leur parcours scolaire au contact de leurs pairs et des adultes de référence, soit dans leur milieu familial, soit avec les enseignants (Doudin, Martin et Albanese 2001). Il importe donc à l'enseignante de planifier, de structurer, d'intervenir selon les principes de l'enseignement stratégique qui demandent de prendre certains risques en tentant de nouvelles expériences avec l'intention de provoquer des changements. A la lecture de ce mémoire vous découvrirez des concepts peu connus dans le monde passionnant de l'enseignement spécialisé. Pourquoi ? Peut- être parce qu'ils nous poussent à avoir une réflexion approfondie sur nos choix et nos méthodes pédagogiques et qu'ils viennent bouleverser nos idées préconçues ou nos habitudes ! Ou alors, parce que l'ouverture d'esprit qui est nécessaire à la mise en place de tels changements nous remet trop en question ! Dans tous les cas vous ne prendrez aucun risque à lire ce mémoire !

Delayed binary and multicomponent gas diffusion in conical tubes

description: Catalyst pores are typically non-uniform along their longitudinal axis, and the transport of gaseous reactants and products takes place in a somehow tapered confinement. In a previous study we observed a diffusion delay in single tapered pores by means of a transient two-bulb-diffusion-cell (Veltzke et al., 2015). Processes in heterogeneous catalysis, however, are typically operated under steady state conditions. Hence also the diffusion processes are non-transient and reactant species are permanently consumed while product species steadily emerge. To mimic steady-state multicomponent diffusion in a cone, we developed a novel two-pipe-diffusion-cell and described the mass transport by an analytical model. Here we can show that the delay effect, which is caused by volumetric changes in longitudinal direction, also exists for steady-state binary and multicomponent diffusion. It is experimentally confirmed that the diffusion hindrance increases with conicity of the test tube. Also the results are transferable to those of the transient two-bulb-diffusion-cell. The measurement of steady-state experiments, however, is much faster.

description: Ce travail est né de la constatation des difficultés récurrentes rencontrées par des élèves fréquentant des groupes ressources dans l'apprentissage de la lecture. Il tend à définir une action pédagogique cohérente dans un contexte de l'enseignement spécialisé intégré dans une institution scolaire ordinaire. Une analyse du contenu de l'apprentissage de la lecture/écriture, se référant aux recherches récentes de la psychologie cognitive, fait émerger les connaissances et les procédures qui sous-tendent de façon interactive ce savoir faire complexe. D'autre part, un bilan diagnostique des compétences des élèves par le Médial (Ouzoulias, 2004) situe leurs acquis et permet l'observation d'une difficulté commune au groupe. En situation de lecture, les représentations et les processus mobilisés sont centrés sur l'identification des mots, perçus comme des entités isolées, et ne permettent pas l'accès à la compréhension. Le projet didactique est conçu comme une action ciblée visant à contribuer à la construction du sens en situation de lecture. Les modules didactiques élaborés ont pour objectif de favoriser l'acquisition du raisonnement syntaxique, processus de mise en relation des mots, supposé renforcer la compréhension. Dans un cadre de production écrite authentique, les activités didactiques sont organisées selon une approche métacognitive. Les élèves sont invités à se confronter à des situations- problèmes, à procéder à des échanges métalinguistiques autour du fonctionnement de la langue et à participer à la création d'outils de référence. L'analyse du déroulement des modules didactiques et des résultats d'une deuxième évaluation des élèves par le Médial tente de préciser la contribution du raisonnement syntaxique au savoir lire.

description: Hace algunos años la representación de la comunidad LGBT+ en contenido animado fomentaba estereotipos e ideologías que provocaban estigmatización y afectaban negativamente a los espectadores, especialmente a los que pertenecían a la comunidad LGBT+. Es importante identificar estos mensajes y reconocer el efecto que pueden tener en la audiencia. El propósito de este trabajo es el de analizar la representación de personajes LGBT+ en animaciones consumidas en México con el objetivo de comprender qué mensajes se están transmitiendo al público mexicano sobre la comunidad LGBT+. Utilizando el análisis semiótico desde una perspectiva queer y los tropos contemporáneos se estudiará la forma en que se caracteriza a los personajes pertenecientes a la comunidad LGBT+ y qué tipo de narrativas se crean en torno a ellos.

On the asymptotic stability of the sine-Gordon kink in the energy space

description: We consider the sine-Gordon (SG) equation in 1+1 dimensions. The kink is a static, non-symmetric exact solution to SG, stable in the energy space $H^1\times L^2$. It is well-known that the linearized operator around the kink has a simple kernel and no internal modes. However, it possesses an odd resonance at the bottom of the continuum spectrum, deeply related to the existence of the (in)famous wobbling kink, an explicit periodic-in-time solution of SG around the kink that contradicts the asymptotic stability of the kink in the energy space. In this paper, we further investigate the influence of resonances in the asymptotic stability question. We also discuss the relationship between breathers, wobbling kinks and resonances in the SG setting. By gathering Bäcklund transformations (BT) and Virial estimates around odd perturbations of the vacuum solution, we first identify the manifold of initial data around zero under which BTs are related to the wobbling kink solution. It turns out that (even) small breathers are deeply related to odd perturbations around the kink, including the wobbling kink itself. As a consequence of this result, using BTs we can construct a smooth manifold of initial data close to the kink, for which there is asymptotic stability in the energy space. The initial data has spatial symmetry of the form (kink + odd, even), non-resonant in principle, and not preserved by the flow. This asymptotic stability property holds despite the existence of wobbling kinks in SG. We also show that wobbling kinks are orbitally stable under odd data, and clarify some interesting connections between SG and $ϕ^4$ at the level of linear Bäcklund transformations.

description: BRITE-Constellation (where BRITE stands for BRIght Target Explorer) is an international nanosatellite mission to monitor photometrically, in two colours, the brightness and temperature variations of stars generally brighter than mag(V) ~ 4, with precision and time coverage not possible from the ground. The current mission design consists of six nanosats (hence Constellation): two from Austria, two from Canada, and two from Poland. Each 7 kg nanosat carries an optical telescope of aperture 3 cm feeding an uncooled CCD. One instrument in each pair is equipped with a blue filter, the other with a red filter. Each BRITE instrument has a wide field of view (~24 degrees), so up to about 15 bright stars can be observed simultaneously, sampled in 32 pixel x 32 pixel sub-rasters. Photometry of additional fainter targets, with reduced precision but thorough time sampling, will be possible through onboard data processing. The BRITE sample is dominated by the most intrinsically luminous stars: massive stars seen at all evolutionary stages, and evolved medium-class stars at the very end of their nuclear burning phases. The goals of BRITE-Constellation are to (1) measure p- and g-mode pulsations to probe the interiors and ages of stars through asteroseismology; (2) look for varying spots on the stars surfaces carried across the stellar disks by rotation, which are the sources of co-rotating interaction regions in the winds of the most luminous stars, probably arising from magnetic subsurface convection; and (3) search for planetary transits.
