description: Aujourd’hui, de nombreux didacticiens et pédagogues sont favorables à l’utilisation du jeu dans l’enseignement, et ce dernier fait partie intégrante de la formation à la Haute École Pédagogique de Lausanne. Pourtant, sa place dans la pratique des enseignants est loin d’être acquise et sa définition reste floue. À travers l’emploi du jeu dans l’enseignement de la géographie au secondaire I, il s’agit de s’interroger sur la pertinence de l’utilisation de celui-ci en tant qu’outil mobilisateur des concepts intégrateurs en géographie. Après un détour par l’histoire du jeu et de sa pratique, le travail se concentre sur les représentations des enseignants et des élèves au secondaire I. Pour ce faire, une recherche a été menée par le biais d’un questionnaire cherchant à comprendre l’utilisation que les enseignants font du jeu. Un sondage a également été réalisé, afin de connaître l’accueil que les élèves réservent à ce dispositif d’enseignement-apprentissage. De plus, ce mémoire présente la mise en place de deux jeux, l’un au CYT et l’autre en 8VSO. Le premier est un jeu de simulation en lien avec la géomorphologie karstique du Jura, alors que le second est un jeu de rôles autour du complexe touristique de la station d’Aminona en Valais. L’analyse des résultats de notre recherche montre le clivage entre la faible utilisation par les collègues de cette modalité d’enseignement face à l’enthousiasme des élèves. Pourtant, le jeu permet non seulement de mettre en pratique les concepts intégrateurs de la géographie au travers de situations concrètes, mais il permet également d’acquérir des capacités transversales, telles que la démarche réflexive, la collaboration ou encore la communication. Ainsi, le jeu peut être considéré comme un moyen privilégié de rendre les concepts, notions et outils de la géographie plus accessibles aux élèves, en y intégrant un facteur motivationnel.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Quantum field theories can have both continuous and finite 0-form symmetries. We study global symmetry structures that arise when both kinds of 0-form symmetries are present. The global structure associated to continuous 0-form symmetries is described by a connected Lie group, which captures the possible backgrounds of the continuous 0-form symmetries the theory can be coupled to. Finite 0-form symmetries can act as outer-automorphisms of this connected Lie group. Consequently, possible background couplings to both continuous and finite 0-form symmetries are described by a disconnected Lie group, and we call the resulting symmetry structure a disconnected 0-form symmetry. Additionally, finite 0-form symmetries may act on the 1-form symmetry group. The 1-form symmetries and continuous 0-form symmetries may combine to form a 2-group, which when combined with finite 0-form symmetries leads to another type of 2-group, that we call a disconnected 2-group and the resulting symmetry structure a disconnected 2-group symmetry. Examples of arbitrarily complex disconnected 0-form and 2-group symmetries in any spacetime dimension are furnished by gauge theories: with 1-form symmetries arising from the center of the gauge group, continuous 0-form symmetries arising as flavor symmetries acting on matter content, and finite 0-form symmetries arising from outer-automorphisms of gauge and flavor Lie algebras.

Complete hyperentangled Greenberger-Horne-Zeilinger state analysis for polarization and time-bin hyperentanglement

Year: 2022
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We present an efficient scheme for the complete analysis of hyperentangled Greenberger-Horne-Zeilinger (GHZ) state in polarization and time-bin degrees of freedom with two steps. First, the polarization GHZ state is distinguished completely and nondestructively, resorting to the controlled phase flip (CPF) gate constructed by the cavity-assisted interaction. Subsequently, the time-bin GHZ state is analyzed by using the preserved polarization entanglement. With the help of CPF gate and self-assisted mechanism, our scheme can be directly generalized to the complete N-photon hyperentangled GHZ state analysis, and it may have potential applications in the hyperentanglement-based quantum communication.

description: The first purpose of this systematic review is to describe how empirical studies on the applications of the 5E instructional model are distributed according to certain variables. The second purpose is to determine how the 5E model has shown a trend in empirical studies in the transition from inquiry-based teaching to STEM education over the years within the scope of learning outcomes of the 5E model. A total of 74 empirical articles out of the 201 obtained from the initial search with the keyword ‘5E model’ in the Web of Science (WoS) and Education Resources Information Center (ERIC) databases were subjected to descriptive and content analysis. The outstanding conclusion from the synthesis of these empirical studies in which the 5E model was implemented is that the 5E model, which has had a broad impact for a long time, focused on its effects on sublevel thinking levels of Bloom's taxonomy (knowledge, understand), and its effects on higher-order thinking levels, which have a crucial place in science education, are overshadowed. Based on these results, a ‘skill-based STEM instructional model’ with an activity set prepared by the model has been proposed in this study concerning 21-st century skills based on the 5E model.
Search for direct $CP$ violation in charged charmless $B \to PV$ decays

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Measurements of $CP$ asymmetry in charmless $B\to PV$ decays are presented, where $P$ and $V$ denote a pseudoscalar and a vector meson, respectively. Five different $B\to PV$ decays from four final states, $B^\pm \to π^\pm π^+ π^-$, $B^\pm \to K^\pm π^+ π^-$, $B^\pm \to K^\pm K^+ K^-$ and $B^\pm \to π^\pm K^+ K^-$ are analyzed. The measurements are based on a method that does not require full amplitude analyses, and are performed using proton-proton collision data at a center-of-mass energy of 13 TeV collected by LHCb between 2015 and 2018, corresponding to an integrated luminosity of 5.9 fb$^{-1}$. In the $π^+ π^-$ $\textit{P}$-wave, in the region dominated by the $B^\pm \to ρ(770)^0 K^\pm$ decay, a $CP$ asymmetry of $\mbox{$A_{CP}$ = +0.150 $\pm$ 0.019 $\pm$ 0.011}$ is measured, where the first uncertainty is statistical and the second is systematic. This is the first observation of $CP$ violation in this process. For the other four decay channels, in regions dominated by the $B^\pm \to ρ(770)^0 π^\pm$, $B^\pm \to \overset{(-)}{K^*}(892)^0 π^\pm$, $B^\pm \to \overset{(-)}{K^*}(892)^0 K^\pm$ and $B^\pm \to ϕ(1020) K^\pm$ decays, $CP$ asymmetries in the $\textit{P}$-wave compatible with zero are measured.

DISH: A Distributed Hybrid Primal-Dual Optimization Framework to Utilize System Heterogeneity

description: We consider solving distributed consensus optimization problems over multi-agent networks. Current distributed methods fail to capture the heterogeneity among agents' local computation capacities. We propose DISH as a distributed hybrid primal-dual algorithmic framework to handle and utilize system heterogeneity. Specifically, DISH allows those agents with higher computational capabilities or cheaper computational costs to implement Newton-type updates locally, while other agents can adopt the much simpler gradient-type updates. We show that DISH is a general framework and includes EXTRA, DIGing, and ESOM-0 as special cases. Moreover, when all agents take both primal and dual Newton-type updates, DISH approximates Newton's method by estimating both primal and dual Hessians. Theoretically, we show that DISH achieves a linear (Q-linear) convergence rate to the exact optimal solution for strongly convex functions, regardless of agents' choices of gradient-type and Newton-type updates. Finally, we perform numerical studies to demonstrate the efficacy of DISH in practice. To the best of our knowledge, DISH is the first hybrid method allowing heterogeneous local updates for distributed consensus optimization under general network topology with provable convergence and rate guarantees.

description: El tomate es la segunda hortaliza producida a nivel mundial y es ampliamente consumido por su versatilidad culinaria y su valor nutricional. Sin embargo, se puede perder hasta la mitad de su producción total a lo largo de toda la cadena de producción, los mercados locales tienen una contribución importante al desperdicio de tomate ya que este es susceptible al daño físico durante el transporte. Estos residuos representan una fuente de compuestos bioactivos, por lo que el tratamiento adecuado permite revalorizar los residuos de tomate. Por lo anterior, la materia prima que sirvió de base para este estudio fueron residuos de tomate recolectados en diferentes mercados de la ciudad de Mexicali, Baja California se deshidrataron a diferentes tiempos (24, 48 y 72 horas) y temperaturas (50, 60 y 70 °C) para obtener polvo de tomate. Se determinó la capacidad antioxidante, el contenido de compuestos polifenólicos y carotenoides, se cuantificaron azucares reductores, proteínas, humedad y cenizas, con la finalidad de identificar el tratamiento que presentara mejor retención de compuestos bioactivos. Se encontró que el tratamiento térmico de 60°C durante 24 horas presentó la mayor capacidad antioxidante (50.79 ± 2.62 % de inhibición de DPPH), y de compuestos polifenólicos (48.12 ± 0.30 mg/g). Asimismo, se evaluó la estabilidad del pH, los 0Brix y la calidad microbiológica durante 50 días de almacenamiento del polvo de tomate que recibió el tratamiento térmico de 60°C durante 24 horas; finalmente, se realizó un análisis sensorial para determinar la aceptabilidad del polvo de tomate. Los resultados obtenidos indican el tratamiento más adecuado para obtener un polvo de tomate que pueda ser utilizado como ingrediente en la formulación de alimentos funcionales.

description: We present detailed numerical simulations of Josephson vortices in a long Josephson junction perpendicular to a thin film screen under strong dc and ac magnetic fields. By solving the sine-Gordon equation, we calculated the threshold magnetic field for penetration of fluxons as a function of frequency, and the power dissipated by oscillating fluxons as functions of the ac field amplitude and frequency. We considered the effects of superimposed ac and dc fields, and a bi-harmonic magnetic field resulting in a vortex ratchet dynamics. The results were used to evaluate the contribution of weak-linked grain boundaries to the nonlinear surface resistance of polycrystalline superconductors under strong electromagnetic fields, particularly thin film screens and resonator cavities.

description: The wave nature of light is revealed by diffraction from physical structures. We report a time-domain version of the classic Young's double-slit experiment: a beam of light twice gated in time produces an interference in the frequency spectrum. The 'time slits', narrow enough to produce diffraction at optical frequencies, are generated from a thin film of Indium-Tin-Oxide illuminated with high-power infrared pulses, inducing a fast reflectivity rise, followed by a slower decay. Separation between the time slits determines the period of oscillations in the frequency spectrum, while the decay of fringe visibility in frequency reveals the shape of the time slits. Here we find a surprise: many more oscillations are visible than expected from existing theory, implying a rise time for the leading edge of around 1-10 fs, approaching an optical cycle of 4.4 fs. This is over an order of magnitude faster than the width of the pump and can be inferred from the decay of the frequency oscillations.

description: Les représentations sociales sont présentes dans la vie mentale quotidienne de chacun et constitutives de notre pensée. Les idées justes en relèvent tout autant que les idées fausses. Ainsi, la réalité n’est pas ce qu’elle est, mais ce qu’elles en font. Dans le contexte particulier de scolarisation d’enfants en situation de handicap en classe ordinaire, la confrontation au handicap pour les élèves réguliers n’est pas sans implications. Plus concrètement, accueillir un enfant en situation de handicap dans une classe ordinaire, c’est non seulement parler de la différence, mais mettre des mots sur le handicap, sur le trouble d’apprentissage, sur la difficulté. C’est mettre en mot ce qui se voit, se perçoit, se devine. Dans ce travail qui fait l’objet d’une étude de cas, il nous tient à coeur de donner la parole aux élèves, de tout mettre en oeuvre pour les entendre et ainsi mieux connaître leurs représentations face à leur camarade en situation de handicap scolarisée dans leur classe.

description: Cette recherche traite d’une question cruciale par rapport au développement des compétences métaémotionnelles des élèves en situation de handicap en milieu scolaire : celle des caractéristiques contextuelles faisant émerger des émotions agréables ou désagréables. Dans le contexte de l’enseignement ordinaire, diverses études mettent en évidence l’importance d’une prise en compte du ressenti. Ce constat est, de toute évidence, encore davantage présent dans le cadre de l’enseignement spécialisé compte tenu des fréquentes difficultés scolaires ou sociales rencontrées par les élèves en situation de handicap. L’objectif de ce travail est donc d’examiner les caractéristiques scolaires favorisant l’apparition d’instants générant des émotions agréables et désagréables dans le contexte de la classe spéciale. Une meilleure connaissance des situations scolaires présentant une charge affective pour les élèves ayant un retard mental pourrait nous permettre, dans le futur, de mieux prendre en compte cette dimension et ainsi de favoriser leur réussite scolaire.

description: We build a field level emulator for cosmic structure formation that is accurate in the nonlinear regime. Our emulator consists of two convolutional neural networks trained to output the nonlinear displacements and velocities of N-body simulation particles based on their linear inputs. Cosmology dependence is encoded in the form of style parameters at each layer of the neural network, enabling the emulator to effectively interpolate the outcomes of structure formation between different flat $Λ$CDM cosmologies over a wide range of background matter densities. The neural network architecture makes the model differentiable by construction, providing a powerful tool for fast field level inference. We test the accuracy of our method by considering several summary statistics, including the density power spectrum with and without redshift space distortions, the displacement power spectrum, the momentum power spectrum, the density bispectrum, halo abundances, and halo profiles with and without redshift space distortions. We compare these statistics from our emulator with the full N-body results, the COLA method, and a fiducial neural network with no cosmological dependence. We find our emulator gives accurate results down to scales of $k \sim 1\ \mathrm{Mpc}^{-1}\, h$, representing a considerable improvement over both COLA and the fiducial neural network. We also demonstrate that our emulator generalizes well to initial conditions containing primordial non-Gaussianity, without the need for any additional style parameters or retraining.

Tripod configurations of curves

description: Tripod configurations of plane curves, formed by certain triples of normal lines coinciding at a point, were introduced by Tabachnikov, who showed that $C^2$ closed convex curves possess at least two tripod configurations. Later, Kao and Wang established the existence of tripod configurations for $C^2$ closed locally convex curves. In this paper we generalize these two results, answering a conjecture of Tabachnikov on the existence of tripod configurations for all $C^2$ closed plane curves by proving existence for a generalized notion of tripod configuration. We then demonstrate the existence of the natural extensions of these tripod configurations to the spherical and hyperbolic geometries for a certain class of convex curves, and discuss an analogue of the problem for regular plane polygons.

description: Despite an intense theoretical and experimental effort over the past decade, observations of the extragalactic radio background at multiple frequencies below 10 GHz are not understood in terms of known radio sources, and may represent a sign of new physics. In this Letter we identify a new class of dark sector models with feebly interacting particles, where dark photons oscillate into ordinary photons that contribute to the radio background. Our scenario can explain both the magnitude and the spectral index of the radio background, while being consistent with other cosmological and astrophysical constraints. These models predict new relativistic degrees of freedom and spectral distortions of the cosmic microwave background, which could be detected in the next generation of experiments.

description: Intrinsic spectrum that results from the coupling of spontaneous emission in a laser cavity, can determine the energy concentration and coherence of lasers, which is crucial for the optical high-precision measurement. Up to now, it is hard to analyze the intrinsic spectrum in the high-speed laser dynamics process, especially under the condition of fast wavelength sweeping. In this work, a new method to analyze the laser intrinsic spectrum is proposed with the laser energy decomposition to a series of chirp-frequency signals, which is realized by fractional Fourier transform (FRFT) of the coherently reconstructed laser waveform. The new understanding of the energy distribution of lasers contributes to the accurate characterization of laser dynamical parameters in time-frequency domain. In the proof-of-concept experiment, the time-frequency dynamical process of a commercial wavelength swept laser is tested with different wavelength-scanning speeds, and the most suitable measurement time window width required for the FRFT-based narrowest spectrum is also explored. The proposed analysis method of laser dynamical parameters will promote the understanding of laser dynamics, and benefit for the optical precision measurement applications.

description: In a recent work, restricted Schur polynomials have been argued to form a complete orthogonal set of gauge invariant operators for the 1/4-BPS sector of free N = 4 super Yang-Mills theory with an SO(N) gauge group. In this work, we extend these results to the theory with an Sp(N) gauge group. Using these operators, we develop techniques to compute correlation functions of any multi-trace operators with two scalar fields exactly in the free theory limit for both SO(N) and Sp(N).

This includes an electric flux-tube in five-dimensional Einstein-Maxwell theory, as well as the standard flux-branes of string theory. The flux always causes the black hole to grow indefinitely. One finds a similar restriction in a Kaluza-Klein setting where the higher dimensional spacetime contains no matter.

description: Dans le cadre de notre travail de recherche, nous nous sommes intéressée à la problématique d’enfants rencontrant des difficultés d’autonomie en classe enfantine. Nous souhaitons découvrir ce qui peut être mis en place pour aider de tels élèves à devenir plus autonomes afin de leur permettre de suivre leur scolarité de la manière la plus aisée possible. Notre but est de jouer notre rôle d’enseignante d’appui pédagogique intégré en venant en aide à ces enfants et à leur enseignante en leur proposant certains dispositifs découverts dans la littérature et pouvant favoriser leur autonomie. Pour étudier ce sujet, nous nous sommes appuyée sur le concept d’autonomie. Nous avons également découvert et développé certains concepts sous-jacents qui sont en étroit lien avec cette notion. Il s’agit de l’esprit d’initiative, de la responsabilisation, de la confiance en soi et de la motivation. En nous appuyant sur la littérature parcourue, nous avons également découvert plusieurs dispositifs permettant de favoriser l’autonomie d’apprenants. Pour notre expérimentation, notre choix s’est porté sur le plan de travail, les métiers, les défis et l’auto- évaluation. Afin de rendre compte de la progression des élèves en difficulté de la classe enfantine dans laquelle notre recherche s’est déroulée, nous avons élaboré une grille d’observation, un questionnaire et différentes grilles d’entretiens. Nous avons ensuite pu analyser et interpréter les données récoltées afin de trouver des réponses à nos différentes interrogations. L’analyse des données et l’interprétation des résultats nous permettent de constater que les dispositifs choisis semblent effectivement favoriser l’autonomie des élèves en difficulté d’autonomie d’une classe enfantine. Cependant, étant donné l’hétérogénéité des enfants constituant notre échantillon, nous remarquons que tous ne progressent pas de la même manière, ni au même rythme. Nous découvrons entre autres l’importance de leur laisser du temps afin de s’approprier les dispositifs proposés et de pouvoir réellement constater une progression positive. De plus, nous prenons conscience à quel point l’attitude de l’enseignant est importante dans le développement de l’autonomie.

description: Questo lavoro di tesi si inserisce nel filone degli studi di management delle imprese discografiche. Attraverso lo sviluppo del concetto di autenticità si è provato a fornire agli addetti ai lavori un approccio alternativo per la promozione di artisti e supporti discografici, mirata ad ottenere un vantaggio di lungo periodo. Il lavoro si articola in tre capitoli: nel primo è stata condotta l'analisi della letteratura sul concetto di autenticità; nel secondo, invece, è stata fatta una descrizione dell'industria discografica, mentre nel terzo, attraverso tre distinte linee di ricerca (survey, intervista ermeneutica e caso di studio), è stato indagato il concetto di autenticità così come inteso da consumatori, musicisti e venditori. Lo scopo è stato quello di comprendere se e in che modo l'interazione di queste tre figure cruciali possa portare a guardare alle imprese discografiche in un'ottica di “responsabilità socio-culturale”. [a cura dell'Autore]
description: This thesis joins the field of management studies of music-industry enterprises. Throughout the development of the concept of the authenticity, the author tried to identify an alternative approach for the benefits of professionals in order both to promote artists and to support label owners, aimed to obtain a long term competitive advantage. This work is composed by three chapters: in the first chapter, the author focuses on the literature review about authenticity; in the second one, instead, a frame of the music industry has been drawn; whereas, the third chapter, through the application of three main research methods (survey,hermeneutics interview and case study), the author investigated the concept of authenticity from the point of view of consumers, musicians and retailers. The aim of this work is to understand, if an interaction between the above quoted three stakeholders could exist, how it should lead the scholars to study the music industry firms under a “socio-cultural responsibility” lens.

description: Evolutionary transitions among ecological interactions are widely known, although their detailed dynamics remain absent for most population models. Adaptive dynamics has been used to illustrate how the parameters of population models might shift through evolution, but within an ecological regime. Here we use adaptive dynamics combined with a generalised logistic model of population dynamics to show that transitions of ecological interactions might appear as a consequence of evolution. To this purpose we introduce a two-microbial toy model in which population parameters are determined by a bookkeeping of resources taken from (and excreted to) the environment, as well as from the byproducts of the other species. Despite its simplicity, this model exhibits all kinds of potential ecological transitions, some of which resemble those found in nature. Overall, the model shows a clear trend toward the emergence of mutualism.

description: Dans ce mémoire de master qui termine une formation en enseignement spécialisé, c’est la technique du topogramme qui a été conceptualisée et testée. Celle-ci devait permettre aux élèves en difficultés d’apprentissage d’améliorer leurs résultats, principalement en structurant différemment les informations d’une leçon. Cet outil est également connu sous le nom de schéma (ou carte) heuristique, de carte d’organisation d’idées ou encore de mind map. Etant donné que les élèves de l’Appui Pédagogique Intégré (API)1 côtoyés jusqu’à maintenant – contexte dans lequel se déroule la partie expérimentale de ce mémoire – manquaient souvent de méthode de travail face à l’apprentissage des leçons, la mise en place d’un tel projet paraissait donc tout à fait justifiée et intéressante. D’un point de vue théorique, cet outil sera mis en lien avec le fonctionnement du cerveau puis avec celui de la mémoire. Ces deux concepts permettront de comprendre en quoi la technique du topogramme peut favoriser une structuration de la matière en lien avec le fonctionnement cortical, facilitant ainsi le passage de la mémoire à court terme vers la mémoire à long terme et améliorant par conséquent les résultats. Il sera ensuite testé auprès de quatre élèves éprouvant des difficultés d’apprentissage. Ce seront les leçons d’environnement qui seront structurées puis étudiées sous forme de topogrammes. L’analyse et l’interprétation des résultats obtenus mettront en évidence si dans ce contexte, l’utilisation de cartes heuristiques peut effectivement aider cette population d’élèves. Cette phase a d’ailleurs révélé de nombreuses variables non envisagées et non prises compte lors des entretiens avec les élèves. Celles-ci pourront ainsi faire l’objet de nouvelles perspectives à explorer avec d’autres élèves.

description: Our ability to uncover complex network structure and dynamics from data is fundamental to understanding and controlling collective dynamics in complex systems. Despite recent progress in this area, reconstructing networks with stochastic dynamical processes from limited time series remains to be an outstanding problem. Here we develop a framework based on compressed sensing to reconstruct complex networks on which stochastic spreading dynamics take place. We apply the methodology to a large number of model and real networks, finding that a full reconstruction of inhomogeneous interactions can be achieved from small amounts of polarized (binary) data, a virtue of compressed sensing. Further, we demonstrate that a hidden source that triggers the spreading process but is externally inaccessible can be ascertained and located with high confidence in the absence of direct routes of propagation from it. Our approach thus establishes a paradigm for tracing and controlling epidemic invasion and information diffusion in complex networked systems.

description: Depuis plusieurs années, les chercheurs s'interrogent sur les liens qu'il peut y avoir entre le fait de « jouer » et « d'apprendre ». Est-ce que l'on apprend en jouant? Sommes-nous toujours conscients de ce qui se passe dans la tête d'un élève lorsqu'il joue? Peut-on dire que lorsqu'un élève joue, il apprend? Et comme le relève encore Brougère (2005), on ne joue pas en général pour apprendre. « On peut donc jouer ou apprendre. Mais il se trouve qu'en jouant il se peut qu'on apprenne, et qu'en apprenant on se trouve face à des situations qui ressemblent de près ou de loin au jeu »(p.166). Nous avons voulu, avec ce mémoire, traverser les différentes étapes d'un jeu, à savoir le jeu de domino et de sa construction avec les élèves jusqu'à l'action proprement dite et observer si les élèves avaient plus de facilité à utiliser leurs prérequis en mathématique en ayant participé à la construction du jeu. Nous avons également essayé de faire ressortir les éléments les plus importants qui pouvaient se passer lors de chaque partie jouée.

description: APOGEE has amassed the largest ever collection of multi-epoch, high-resolution (R~22,500), H-band spectra for B-type emission line (Be) stars. The 128/238 APOGEE Be stars for which emission had never previously been reported serve to increase the total number of known Be stars by ~6%. We focus on identification of the H-band lines and analysis of the emission peak velocity separations (v_p) and emission peak intensity ratios (V/R) of the usually double-peaked H I and non-hydrogen emission lines. H I Br11 emission is found to preferentially form in the circumstellar disks at an average distance of ~2.2 stellar radii. Increasing v_p toward the weaker Br12--Br20 lines suggests these lines are formed interior to Br11. By contrast, the observed IR Fe II emission lines present evidence of having significantly larger formation radii; distinctive phase lags between IR Fe II and H I Brackett emission lines further supports that these species arise from different radii in Be disks. Several emission lines have been identified for the first time including ~16895, a prominent feature in the spectra for almost a fifth of the sample and, as inferred from relatively large v_p compared to the Br11-Br20, a tracer of the inner regions of Be disks. Unlike the typical metallic lines observed for Be stars in the optical, the H-band metallic lines, such as Fe II 16878, never exhibit any evidence of shell absorption, even when the H I lines are clearly shell-dominated. The first known example of a quasi-triple-peaked Br11 line profile is reported for HD 253659, one of several stars exhibiting intra- and/or extra-species V/R and radial velocity variation within individual spectra. Br11 profiles are presented for all discussed stars, as are full APOGEE spectra for a portion of the sample.

description: Un apprentissage nécessite l’élaboration de stratégies cognitives et métacognitives explicites et étayées, au cours de laquelle les dimensions se rapportant à la motivation, au sentiment d’efficacité personnelle et à la capacité de régulation des émotions sont déterminantes. Dans cette perspective, l’élève est considéré comme personne dotée de capacités grâce auxquelles elle peut accéder à la conscientisation de ses procédures cognitives et parvenir à les adapter aux exigences de la mise en forme des savoirs. Dépassant la conception du rattrapage scolaire consistant à “faire toujours plus de la même chose”, l’enseignement psychopédagogique cognitif et stratégique s’inscrit dans le principe fondamental de l’éducabilité cognitive, au service duquel les instruments constructiviste et de médiation sociale sont appliqués : au contact des stratégies appropriées, le potentiel cognitif de chaque élève est susceptible de se déployer. Ce type d’enseignement, développé par Pierre Vianin (2001, 2007, 20091) dans le cadre du degré primaire valaisan, met en place des approches pédagogiques spécifiques ou globales, selon que l’élève se trouve en difficulté ou véritablement en échec scolaire. A la suite de Vianin, je me suis proposé d’insérer progressivement ces méthodes de psychologie cognitive au degré secondaire dans le contexte pédagogique et institutionnel de deux établissements vaudois. Cette recherche pose l’hypothèse que les méthodes cognitives sont, de par leur plasticité, leur adéquation aux besoins cognitifs des élèves et la puissance d’identification qu’elles détiennent auprès de ceux-ci, adaptables au milieu dans lequel elles se trouvent transférées. Certaines particularités propres au contexte secondaire, ainsi que les articulations que le système peut mettre en place afin d’ouvrir à de nouvelles perspectives dans le cadre du renforcement pédagogique sont également analysées. L’enseignement psychopédagogique cognitif et stratégique : de grands mots pour de petits remèdes ? A vous d’apprécier !
