description: Ce mémoire consiste en la mise en place d’un projet dans le cadre de l’éducation à la durabilité à l’école. Ce dernier est structuré par des conseils de classe demandant l’implication totale des élèves-acteurs. Nous avons analysé comment la réalisation d’un projet par des élèves permet de les sensibiliser à la durabilité, les responsabiliser en développant leurs habiletés sociales comme la prise de décision et l’esprit critique au travers du projet ainsi que lors des conseils de classe. Ainsi, sur la base de nos observations, nous avons déterminé que les conseils de classe ont facilité, effectivement, l’atteinte d’un but commun, tout comme la pédagogie de projet a permis le développement de l’esprit critique et la prise de décision des élèves. Les élèves ont été amenés à imaginer des projets autour de la durabilité. Leurs idées ont ensuite été discutées pendant les conseils de classe. Enfin, après ces échanges les élèves ont formulé une procédure pour réaliser leur objectif qu’ils ont mise en place pour le réaliser. Ce dernier prenant la forme de matériel pédagogique durable pour les deux premières années scolaires. Enfin nous avons relevé et considéré les bienfaits des conseils de classe sur le déroulement du projet et la croissance citoyenne des élèves. De ce fait, notre question de recherche incarnait une double problématique soutenue par deux interrogations distinctes : • Dans quelles mesures la pédagogie de projet permet de développer l’esprit critique et la prise de décision des élèves ? • Comment la mise en place de conseil de classe est bénéfique à la réalisation d’un projet ?
Nonlinear ${\cal N}=2$ Supersymmetry and 3D Supersymmetric Born-Infeld Theory

description: D$p$-branes acquire effective nonlinear descriptions whose bosonic part is related to the Born-Infeld action. This nonlinearity has been proven to be a consequence of the partial ${\cal N}=2\to{\cal N}=1$ supersymmetry breaking, originating from the solitonic nature of the branes. In this work, we focus on the effective descriptions of D2-branes. Using the Goldstone multiplet interpretation of the action and the method of nilpotent ${\cal N}=2$ superfields, we construct the 3D, ${\cal N}=1$ superspace effective action which makes the first supersymmetry manifest and realizes the second, spontaneously broken, supersymmetry nonlinearly. We show that there are two such supersymmetric extensions of the 3D Born-Infeld action which correspond to the dynamics of the 3D Maxwell-Goldstone multiplet and the 3D projection of the Tensor-Goldstone multiplet respectively. Moreover, we demonstrate that these results are derived by applying the constrained superfield approach on the ${\cal N}=2, D=3$ vector and chiral multiplets after expanding them around a nontrivial vacuum. We find that these two descriptions are related by a duality transformation which results in the inversion of a dimensionless parameter. For both descriptions we derive the explicit bosonic and fermionic parts of the 3D super Born-Infeld action. Finally, consider the deformation of the Maxwell-Goldstone superspace action by the characteristic Chern-Simons-like, gauge invariant, mass term.

description: To reduce stress in traffic situations, we investigate a possible strategy to support bike swarms by inducing interpersonal synchrony, currently a very popular construct. Synchrony may coordinate movements, reduce stress, and increase the feeling of safety during cycling in a group. Synchrony is a promising construct, but its induction in multisensory situations has not been tested. To induce synchrony in multisensory situations like the street traffic, we use tactile feedback in the form of vibrations, the influence of which has not yet been researched. To this end, we simulated a real traffic scenario in the laboratory. We explored to what extent nonintrusive vibrations can be distinctly perceived when competing with audiovisual input from street traffic, without constituting a distractor from street traffic. In the long term we want to explore possibilities of measuring and inducing synchronous leg movements in bike swarms on demand. This involves detecting the need for synchrony, for instance due to stress and lack of synchrony and prompt cyclists to follow vibration rhythms, in order to induce perceived emotional synchrony with the other group members. We present our conceptual work and technological development towards inducing synchrony through social wearables, and results from a first pilot study.

description: We review the finite element approximation of the classical obstacle problem in energy and max-norms and derive error estimates for both the solution and the free boundary. On the basis of recent regularity results we present an optimal error analysis for the thin obstacle problem. Finally, we discuss the localization of the obstacle problem for the fractional Laplacian and prove quasi-optimal convergence rates.

description: Paul Dean's Septet was commissioned by Andrew Johnston for the Melbourne Ensemble as part of a joint plan between the Melbourne based group and Ensemble Q to grow the repertoire, especially Australia repertoire, for the combinations of both the Beethoven Septet and the Schubert Octet. We think of these groupings of instruments as stuck in the early Romantic era and are simply viewed in many circles as time pieces. But the possibilities are endless. Why didn't the Septet/Octet formations live beyond their short lives is hard to fathom when the success of these two monster pieces was shared by performers and audiences and even critics alike. Many composers from the era tried but failed to hit the mark with their attempts at extending the repertoire. Paul Dean's work, a companion piece to the Beethoven Septet, delves into the contemporary notion of how the pairing and or groupings of instruments within the ensemble can be treated, in a sympathetic and also contrasting way to how Beethoven envisaged the work. With a modern ear for string harmonics, the use of the bass clarinet, an enlarged role for the double bass and bassoon, and a strong sense of bitonality and polytonality, Dean has created a work that gives life to the "museum" ensemble in an exciting, imaginative and compelling way. The second movement stands out as an emotional outpouring to the memory of his cousin who died suddenly from a late cancer diagnosis, and the last mvt Tarantella gives a frenetic life to an old dance form whilst paying tribute to the ghost of Beethoven in the room.

description: We provide the modified TOV equations for the hydrostatic equilibrium of charged compact stars within the metric $f(R)$ gravitational background. We adopt the MIT bag model EoS for the dense matter and assume a charge distribution where the electric charge density $ρ_{\rm ch}$ is proportional to the standard energy density $ρ$. Using the Starobinsky model, we explore the role of the $αR^2$ term, where $α$ is a free constant and $R$ the Ricci scalar, on the global properties of charged stars such as radius, mass and total charge. We present the dependence of the structure of the star for several values of $α$ and for different values of the constant parameter $β\equiv ρ_{\rm ch}/ρ$. Remarkably, we find that the radius decreases with respect to its GR value for low central densities, while the opposite occurs in the high-central-density region. The mass measured at the surface always decreases and the maximum-total charge undergoes a substantial increase as the parameter $α$ increases. We also illustrate the variations of the asymptotic mass as a consequence of the electric charge and the extra quadratic term.

description: Le concept de genre fait partie de la vie quotidienne de tout individu et ceci commence même avant la naissance de l’enfant. Les inégalités de genre se mettent en place dès la socialisation primaire de l’enfant. Elles se retrouvent à l’école, puis dans le choix des orientations professionnelles et enfin à l’âge adulte, dans la vie active comme dans la vie quotidienne. De nos jours, les “éducation à” se développent à l’école et nous avons ainsi choisi de porter notre attention sur l’éducation au genre. Nous avons également choisi de nous pencher sur les élèves à besoins éducatifs particuliers au sein des classes, notamment sur leur motivation. Ces éléments ont été associés pour formuler la question de recherche suivante : la motivation des élèves à besoins éducatifs particuliers est-elle améliorée par la mise en œuvre de séquences d’éducation au genre, plus qu’avec une discipline ordinaire comme le français ou les mathématiques ? Nous avons ainsi réalisé une étude de cas dans notre classe de stage, avec des élèves de 3H. Suite à la mise en œuvre de séquences d’éducation au genre, nous avons effectué des observations, des entrevues individuelles et collectives avec les élèves. Un des aspects centraux de notre travail a été de trouver les outils adaptés pour effectuer une recherche avec des élèves très jeunes (entre 6 et 7 ans) et supposés à besoins éducatifs particuliers. Au cours de cette recherche, nous avons pu constater qu’il est assez difficile pour des élèves si jeunes de comprendre ces enjeux et de s’engager dans des raisonnements aussi complexes. Leurs réponses sont ainsi parfois très limitées, ils retiennent davantage l'aspect ludique de la séquence que le thème central. Cependant, des réponses et des observations intéressantes ont permis de répondre à notre question de recherche et à nos hypothèses. Notre travail s’articule en deux volets : une partie portant sur la théorie et une autre portant sur la mise en pratique et la recherche en tant que telle. La partie théorique comprend les définitions et les explications des termes intimement liés au genre ainsi qu’à l’”éducation à”. Quant à la partie pratique, elle explique notre méthode d’étude de cas, le déroulement de nos séquences d’éducation au genre et enfin leurs résultats et l'analyse de ces derniers.

description: situational awareness. However, there are limited applications for vulnerable road users (VRU) to collaborate with the infrastructure and other users.This position paper proposes integrating V2X into active noise-canceling (ANC) headphones to enhance safety and reduce stress in traffic by incorporating warning sounds when required. In previous research, we explored the use of augmented soundscapes played through ANC headphones, utilizing signals and altered step sounds to convey cues and warn pedestrians of potential collisions. The potential of this application in supporting drivers of micromobility vehicles, such as e-scooters, is discussed. Additionally, this paper presents a scenario involving the soundscape of a concert to illustrate the concept for novel forms of future multimodal mobility. We conclude this paper by discussing how such an application could be evaluated.

description: We make a time-dependent characterization of pulsar wind nebulae (PWNe) surrounding some of the highest spin-down pulsars that have not yet been detected at TeV. Our aim is assessing their possible level of magnetization. We analyze the nebulae driven by J2022+3842 in G76.9+1.0, J0540-6919 in N158A (the Crab twin), J1400--6325 in G310.6--1.6, and J1124--5916 in G292.0+0.18, none of which have been found at TeV energies. For comparison we refer to published models of G54.1+0.3, the Crab nebula, and develop a model for N157B in the Large Magellanic Cloud (LMC). We conclude that further observations of N158A could lead to its detection at VHE. According to our model, a FIR energy density of 5 eV cm$^{-3}$ could already lead to a detection in H.E.S.S. (assuming no other IC target field) within 50 hours of exposure and just the CMB inverse Compton contribution would produce VHE photons at the CTA sensitivity. We also propose models for G76.9+1.0, G310.6--1.6 and G292.0+1.8 which suggest their TeV detection in a moderate exposure for the latter two with the current generation of Cherenkov telescopes. We analyze the possibility that these PWNe are highly magnetized, where the low number of particles explains the residual detection in X-rays and their lack of detection at TeV energies.

description: Dans le cadre de notre formation à la Haute École Pédagogique de Lausanne (HEP), nous nous sommes intéressées à l’évaluation critériée dans un contexte formatif. Durant notre formation, mais également sur le terrain, lors de nos divers stages et remplacements, nous avons pu observer qu’il existait une multitude de manières pour évaluer les élèves. Nous nous sommes alors penchées sur l’évaluation critériée formative. En effet, nous avons pu voir que certaines recherches montrent que la pratique régulière de l’évaluation critériée comporte divers aspects bénéfiques, tant pour les apprenant×e×s que pour les enseignant×e×s. Elle permet de rendre visible les apprentissages des élèves, contrairement à l’évaluation, largement répandue, qui se formalise à travers une addition de points faisant perdre l’information de ce qui est acquis ou non. Avec l’évaluation critériée, l’enseignant×e peut alors adapter son enseignement aux besoins de ses apprenant×e×s et leur donner des feedbacks. De plus, elle permet de rendre les élèves autonomes dans l’acquisition de savoirs à maîtriser, car elle permet l’autorégulation des apprentissages à l’aide d’une échelle de niveau qui leur permet de se situer. Durant notre formation, nous avons observé que cette pratique évaluative était peu pratiquée sur le terrain. Sa création, ainsi que sa mise en place concrète au sein des classes, sont par ailleurs encore peu développées dans la littérature. Par conséquent, la création et la sélection des différents critères sont des notions qui restent souvent floues et mal comprises. Dans ce travail, nous souhaitons identifier les différentes démarches afin de comprendre comment sélectionner et créer de bons critères d’évaluations, qui permettent d’aider les enseignant×e×s et les élèves. Pour ce faire, nous avons interrogé différent×e×s enseignant×e×s et différent×e×s élèves au sein de nos classes de stage et nous avons avons conçu des grilles critériées. Le but de notre recherche est de comprendre comment concevoir et mettre en place une évaluation critériée formative en classe pour permettre aux élèves d'autoréguler leurs apprentissages et à l’enseignant×e d’adapter son enseignement.

description: (Abridged) We aim to determine the trigonometric parallaxes and proper motions of a sample of ten field L0-L5 dwarfs with spectroscopic evidence for low-gravity atmospheres. We obtained J and Ks imaging data using 2-4-m class telescopes with a typical cadence of one image per month between 2010 January and 2012 December. We also obtained low resolution optical spectra (R~300, 500-1100 nm) using the 10-m GTCs to assess the presence of lithium absorption in four targets and confirm their young age. Trigonometric parallaxes and proper motions were derived to typical accuracies of 1 mas and +/-10 mas/yr. All ten L dwarfs have large motions, and are located at distances between 9 and 47 pc. They lie above and on the sequence of field dwarfs in the absolute J and K_s magnitude versus spectral type and luminosity versus Teff diagrams, implying ages similar to or smaller than those typical of the field. The detection of atomic lithium in the atmosphere of 2MASS J00452143+1634446 is reported for the first time. Three dwarfs have locations in the HR diagram indicative of old ages and high masses consistent with the observed lithium depletion previously published. We did not find evidence for the presence of astrometric companions with minimum detectable masses typically >=25 Mjup and face-on, circular orbits with periods between 60-90 d and 3 yr around eight targets. The astrometric and spectroscopic data indicate that about 60-70% of the field L-type dwarfs in our sample with evidence for low-gravity atmospheres are indeed young-to-intermediate-age brown dwarfs of the solar neighborhood with expected ages and masses in the intervals 10-500 Myr and 11-45 Mjup. The peaked-shape of the H-band spectra of L dwarfs, a signpost of youth, appears to be present up to ages of 120-500 Myr and intermediate-to-high gravities.

description: The nonleptonic two-body $Λ_b\rightarrow Λψ$ decays with $ψ=J/ψ$ or $ψ(2S)$ are investigated based on the perturbative QCD approach. These are color-suppressed processes in which the nonfactorizable contributions are confirmed to be dominant. Angular momentum conservation allows us to describe the concerned decays by four independent complex helicity amplitudes. It is observed that the negative-helicity states for the $Λ$ baryon are preferred as expected in the left-handed nature of the charged-current interaction. The obtained results for the helicity amplitudes are used to compute the branching ratios and various observable parameters, which are then compared to the existing theoretical predictions and experimental data. In particular, we predict the ratio $\mathcal{R}=\frac{\mathcal{B}(Λ_b\rightarrowΛψ(2S))}{\mathcal{B}(Λ_b\rightarrowΛJ/ψ)}=0.47^{+0.02}_{-0.00}$ in comparison with $0.508\pm 0.023$ from the Particle Data Group at the level of 1 standard deviation. We also briefly explore the long-distance contributions to the semileptonic $Λ_b \rightarrow Λl^+l^-$ decays in the kinematic regions where the dilepton invariant masses are around the $J/ψ$ and $ψ(2S)$ resonances.

description: L’éducation au développement durable ou l’éducation à la durabilité sont des termes constamment plus présents chez les enseignants. L’éducation à la durabilité figure dans le PER (Plan d’études Romand) comme une des visées prioritaires de la formation générale des élèves. Alors pourquoi est-il si peu fréquent d’observer les enseignants du cycle 1 faire de l’ED ? L’outdoor education, l’enseignement de thèmes liés à l’environnement et l’école à la forêt sont des courants de plus en plus fréquents dans l’enseignement. Cependant, il ne s’agit pas d’éducation à la durabilité. Pour qualifier une activité d’ED, il faut amener les élèves à penser et questionner le monde qui les entoure. Il n’est pas aisé d’aborder des sujets complexes comme la pauvreté, le changement climatique ou encore la surconsommation avec des enfants de 4 à 8 ans. Quels apprentissages faut-il viser ? Comment amener un sujet à nos élèves autour duquel ils n’ont aucune ou presque aucune connaissance ? Quelles pratiques pédagogiques mettre en place pour faire réfléchir les élèves sans rester dans une pensée binaire ? Quels sont les obstacles auquel sont confrontés les enseignants lorsqu’ils font de l’ED et comment les surpasser ? Nous avons décidé de travailler sur le thème de la pauvreté car c’est un sujet peu abordé à l’école. Ce mémoire présente donc le processus par lequel nous sommes passées pour construire une séquence d’ED sur le thème de la pauvreté pour le cycle 1, les obstacles face auxquelles nous avons été confrontées et une analyse de cette séquence. Le mémoire propose également un guide donnant des outils pour travailler un sujet complexe comme la pauvreté au cycle 1 dans une optique de durabilité.
title: Safe and Secure? Visions of Military Human-Computer Interaction
Creators: name: Schmid, Stefka
Publisher: name: GI

description: Safety-critical human-computer interaction has focused on technology use in life-critical situations, including military operations. Due to the practical relevance of HCI and disciplinary debates about human-centered design, this literature review studies HCI scholarships’ visions of military human-computer interaction. Through text analysis and categorization of publications, it is found that interaction is envisioned to take place in the context of both missionoriented operational (e.g., target detection) as well as organizational tasks (e.g., military training). While artificial intelligence, virtual/augmented reality, and robots are most frequently defined as technological environments, goals, such as situation awareness, enjoyment, and trust are predominantly associated with them. Considering scholarly references to application contexts and different factors of the context of use allows to systematically approach how military human-computer interaction is imagined. Offering insight into research trends in HCI, this first overview of research endeavors also contributes to interdisciplinary debates, such as Security Studies and technology assessment.

description: Le but de chaque enseignant est que la tâche dans laquelle il souhaite faire entrer ses élèves leur permette d’entrer dans les apprentissages et non “de faire pour faire”. Notre travail s’inscrit dans cette thématique et s'appuie plus précisément sur le concept de dévolution instauré par Brousseau (1986). La dévolution provient de la théorie des situations didactiques et définit l’acte par lequel l’enseignant transfère la responsabilité à l’élève de son apprentissage. Notre recherche a été menée dans deux classes différentes du canton de Vaud avec des élèves de 8ème année. Une activité a été créée par nos soins qui s’inscrit dans la discipline des mathématiques. L'activité a été présentée aux élèves sur des appareils numériques (ordinateurs ou iPads). Notre question de recherche concerne plus précisément l’impact des caractéristiques des tâches sur la dévolution. Les élèves ont été filmés en classe et les écrans des appareils numériques enregistrés. Sur cette base, nous avons finalement analysé les différentes données pour nous focaliser sur l’impact de ces dites caractéristiques. Les résultats sont discutés et mis en lien avec la littérature.

description: In the context of modified $f(R)$ gravity, we attempt to study the thermodynamic properties of the evolving Lorentzian wormholes at the apparent horizon. It is shown that the wormhole can be derived from a particular $f(R)$ model in the radiation background. Moreover, it has been shown that the field equations can be cast to a similar form $dE = TdS + WdV + Td\bar{S}$ at the apparent horizon for the evolving Lorentzian wormhole. Compared to the case of Einstein's general relativity, an additional term $Td\bar{S}$ appears here.

description: Notre travail de mémoire s'est inscrit dans une optique de favoriser le climat de classe afin de potentiellement influencer à long terme sur le harcèlement sans pour autant aborder ce point dans notre démarche d’enquête. Notre séquence s’est déroulée sur huit semaines consécutives à partir de la fin des vacances d’octobre jusqu’à celles de Noël. Nous avons mené le projet dans une classe de 7P ainsi que de 8P. Nous avons mis en place dans nos classes cinq activités d’environ une quinzaine de minutes à chaque fois, en commençant par la compréhension des émotions dans leur globalité pour finir plus spécifiquement avec de la sensibilisation et le développement de l’empathie. Chaque activité était en lien avec les émotions et la gestion de celles-ci afin de pouvoir observer les conséquences qu’elles auraient sur le climat de classe. Pour obtenir des résultats, les élèves ont dû remplir un questionnaire au début puis à la fin du projet. Des observations ont été recueillies selon une grille d’analyse. Nous avons complété les questionnaires ainsi que les observations par des discussions menées après chaque activité sur nos vécus et ressentis lors de ces dernières. Nous avons choisi l’empathie car nous voulions que les élèves travaillent sur l’interprétation des émotions des autres afin d’adapter leur comportement entre pairs ou au sein d’un groupe. Au terme de notre projet, nous ne sommes pas arrivées aux résultats escomptés. Cependant, d’autres recherches nous montrent le contraire. D’autres activités ou un projet mené sur une plus longue durée pourraient avoir l’impact espéré. Ce travail s'est inscrit dans une démarche de l’EDD et a mobilisé des compétences du référentiel telles que l’empathie, la responsabilité ainsi que les valeurs.
Extreme beam attenuation in double-slit experiments: Quantum and subquantum scenarios

description: Combining high and low probability densities in intensity hybrids, we study some of their properties in double-slit setups. In particular, we connect to earlier results on beam attenuation techniques in neutron interferometry and study the effects of very small transmission factors, or very low counting rates, respectively, at one of the two slits. We use a "superclassical" modeling procedure which we have previously shown to produce predictions identical with those of standard quantum theory. Although in accordance with the latter, we show that there are previously unexpected new effects in intensity hybrids for transmission factors below $a\lesssim 10^{-4}$, which can eventually be observed with the aid of weak measurement techniques. We denote these as quantum sweeper effects, which are characterized by the bunching together of low counting rate particles within very narrow spatial domains. We give an explanation of this phenomenology by the circumstance that in reaching down to ever weaker channel intensities, the nonlinear nature of the probability density currents becomes ever more important, a fact which is generally not considered - although implicitly present - in standard quantum mechanics.

description: This paper focuses on a game design element that aims to increase the motivation of users to focus on a single aspect while having a strong feeling of free choice. We call this concept "Free Limited Choice" (FLC). To approach this idea, we present two scenarios in different domains - e-learning and eXplainable AI (XAI). XAI in particular, is a quite new field for applying gamification concepts. In first preliminary user studies, we collect data for a first assessment of each scenario and specifically FLC. Based on this data, we conclude that FLC can be a useful concept for the desired purpose, but also highlight different aspects to consider when utilizing it.

description: By participating in the software development process, people with disabilities can have a say in how and for what they want to be supported by the resulting IT artifacts. Although the involvement strengthens the empowerment of this underrepresented target group here, people with intellectual disabilities in particular are still rarely included in the (early) stages of development. In our paper we want to contribute to changing this by presenting the participatory approach to requirements analysis and idea development in the service learning course "Inclusive IT Design" and reflecting on our first insights, also with regard to the empowerment of the target group.
