description: Compelling evidence-though yet no formal proof-has been adduced that the probability that a generic (standard) two-qubit state ($ρ$) is separable/disentangled is $\frac{8}{33}$ (arXiv:1301.6617, arXiv:1109.2560, arXiv:0704.3723). Proceeding in related analytical frameworks, using a further determinantal $4F3$-hypergeometric moment formula (Appendix A), we reach, {\it via} density-approximation procedures, the conclusion that one-half ($\frac{4}{33}$) of this probability arises when the determinantal inequality $|ρ^{PT}|>|ρ|$, where $PT$ denotes the partial transpose, is satisfied, and, the other half, when $|ρ|>|ρ^{PT}|$. These probabilities are taken with respect to the flat, Hilbert-Schmidt measure on the fifteen-dimensional convex set of $4 \times 4$ density matrices. We find fully parallel bisection/equipartition results for the previously adduced, as well, two-"re[al]bit" and two-"quater[nionic]bit"separability probabilities of $\frac{29}{64}$ and $\frac{26}{323}$, respectively. The new determinantal $4F3$-hypergeometric moment formula is, then, adjusted (Appendices B and C) to the boundary case of minimally degenerate states ($|ρ|=0$), and its consistency manifested-also using density-approximation-with a theorem of Szarek, Bengtsson and {Ż}yczkowski (arXiv:quant-ph/0509008). This theorem states that the Hilbert-Schmidt separability probabilities of generic minimally degenerate two-qubit states are (again) one-half those of the corresponding generic nondegenerate states.

description: Using Hitchin's parameterization of the Hitchin-Teichmüller component of the $SL(n,\mathbb{R})$ representation variety, we study the asymptotics of certain families of representations. In fact, for certain Higgs bundles in the $SL(n,\mathbb{R})$-Hitchin component, we study the asymptotics of the Hermitian metric solving the Higgs bundle equations. This analysis is used to estimate the asymptotics of the corresponding family of flat connections as we scale the differentials by a real parameter. We consider Higgs fields that have only one holomorphic differential $q_n$ of degree $n$ or $q_{n-1}$ of degree $n-1.$ We also study the asymptotics of the associated family of equivariant harmonic maps to the symmetric space $SL(n,\mathbb{R})/SO(n,\mathbb{R})$ and relate it to recent work of Katzarkov, Noll, Pandit and Simpson.

description: We describe the generation of stable mode-locked pulse trains from on-chip normal dispersion microresonators. The excitation of hyper-parametric oscillation is facilitated by the local dispersion disruptions induced by mode interactions. The system is then driven from hyper-parametric oscillation to the mode-locked state with over 200 nm spectral width by controlled pump power and detuning. With the continuous-wave driven nonlinearity, the pulses sit on a pedestal, akin to a cavity soliton. We identify the importance of pump detuning and wavelength-dependent quality factors in stabilizing and shaping the pulse structure, to achieve a single pulse inside the cavity. We examine the mode locking dynamics by numerically solving the master equation and provide analytic solutions under appropriate approximations.

description: Past studies have identified a spatially extended excess of $\sim$1-3 GeV gamma rays from the region surrounding the Galactic Center, consistent with the emission expected from annihilating dark matter. We revisit and scrutinize this signal with the intention of further constraining its characteristics and origin. By applying cuts to the \textit{Fermi} event parameter CTBCORE, we suppress the tails of the point spread function and generate high resolution gamma-ray maps, enabling us to more easily separate the various gamma-ray components. Within these maps, we find the GeV excess to be robust and highly statistically significant, with a spectrum, angular distribution, and overall normalization that is in good agreement with that predicted by simple annihilating dark matter models. For example, the signal is very well fit by a 36-51 GeV dark matter particle annihilating to $b\bar{b}$ with an annihilation cross section of $σv = (1-3)\times 10^{-26}$ cm$^3$/s (normalized to a local dark matter density of 0.4 GeV/cm$^3$). Furthermore, we confirm that the angular distribution of the excess is approximately spherically symmetric and centered around the dynamical center of the Milky Way (within $\sim$$0.05^{\circ}$ of Sgr A$^*$), showing no sign of elongation along the Galactic Plane. The signal is observed to extend to at least $\simeq10^{\circ}$ from the Galactic Center, disfavoring the possibility that this emission originates from millisecond pulsars.

description: Ce travail traite de l’influence d’une création musicale collaborative sur le sentiment d’appartenance des élèves de classe d’accueil. En me fondant sur une expérience réalisée avec deux classes de l’établissement secondaire de la région de Montreux, je souhaite observer l’influence de la collaboration créative sur le sentiment d’appartenance des élèves allophones. Ces élèves, dont le niveau de français ne permet pas de suivre une classe régulière vivent dans bien des cas leur scolarité entre eux, jusqu’à ce qu’ils rejoignent une classe régulière pour un stage d’intégration. Les structures mises en place pour ces élèves ont déjà été analysées par la sociologue lausannoise Nathalie Mativaz mais il me semblait pertinent de relever comment en tant qu’enseignante je pouvais participer à une certaine forme d’aide à l’intégration de ces élèves. Permettre à ces élèves de collaborer avec des classes régulières sans l’enjeu de l’intégration définitive, leur donne l’occasion de partager un projet, une expérience qui les rattache à divers membres de l’établissement et ainsi fait évoluer leur sentiment d’appartenance à cette école. La mise en œuvre de ce projet a permis aux élèves allophones, qui sont regroupés dans une classe dite d’accueil, d’expérimenter la diversité des outils qu’ils ont à disposition pour créer des liens avec d’autres classes. Ces liens peuvent en partie s’exprimer par la présence du sentiment d’appartenance au groupe des classes régulières. Ainsi, pour l’observation de la présence du sentiment d’appartenance, je me suis fondée sur les indicateurs proposés par StAmand & Bowen & Wan Jung Lin (2017). Cette démarche hypothético-déductive se construit sur une enquête qualitative qui repose sur trois étapes. Pour commencer, j’ai tenté d’observer l’évolution du sentiment d’appartenance de ces élèves de classe d’accueil, essentiel à une intégration sociale et émotionnelle dans la culture d’accueil. Ensuite, deux périodes de collaboration interclasses ont eu lieu et j’ai pu relever divers éléments quant à l’efficacité de la collaboration. Finalement, un entretien semi-directionnel a permis de recueillir le ressenti et les retours des élèves de la classe d’accueil suite à ces deux périodes. L’analyse qualitative a montré que le sentiment d’appartenance au groupe des pairs de classe régulière est influencé mais qu’il peut se développer de manière diverse. La création collaborative n’a pas été un outil essentiel au développement de ce sentiment mais dans pratiquement chaque groupe, elle a instauré une disposition d’écoute de l’autre propice au développement du sentiment d’appartenance.

description: We derive the classical dynamics of massless charged particles in a rigorous way from first principles. Since due to ultraviolet divergences this dynamics does not follow from an action principle, we rely on a) Maxwell's equations, b) Lorentz- and reparameterization-invariance, c) local conservation of energy and momentum. Despite the presence of pronounced singularities of the electromagnetic field along Dirac-like strings, we give a constructive proof of the existence of a unique distribution-valued energy-momentum tensor. Its conservation requires the particles to obey standard Lorentz equations and they experience, hence, no radiation reaction. Correspondingly the dynamics of interacting classical massless charged particles can be consistently defined, although they do not emit bremsstrahlung end experience no self-interaction.

Subjects: subject: Information Theory (cs.IT)

description: Communication over a broadband fading channel powered by an energy harvesting transmitter is studied. Assuming non-causal knowledge of energy/data arrivals and channel gains, optimal transmission schemes are identified by taking into account the energy cost of the processing circuitry as well as the transmission energy. A constant processing cost for each active sub-channel is assumed. Three different system objectives are considered: i) throughput maximization, in which the total amount of transmitted data by a deadline is maximized for a backlogged transmitter with a finite capacity battery; ii) energy maximization, in which the remaining energy in an infinite capacity battery by a deadline is maximized such that all the arriving data packets are delivered; iii) transmission completion time minimization, in which the delivery time of all the arriving data packets is minimized assuming infinite size battery. For each objective, a convex optimization problem is formulated, the properties of the optimal transmission policies are identified, and an algorithm which computes an optimal transmission policy is proposed. Finally, based on the insights gained from the offline optimizations, low-complexity online algorithms performing close to the optimal dynamic programming solution for the throughput and energy maximization problems are developed under the assumption that the energy/data arrivals and channel states are known causally at the transmitter.

Интерес к препаратам на основе лекарственного сырья природного происхождения повышается с каждым годом. Такую тенденцию возрождения интереса к биопрепаратам объясняют недостатки синтетических лекарственных средств: токсичность, побочные действия и аллергии. По данным ВОЗ, аллергические явления, возникающие в результате применения синтетических лекарственных средств, возникают у 12-18% населения.

description: Dans notre société où le raisonnement scientifique est omniprésent, la pensée rationnelle qui lui est associée est mise en avant en tant que compétence pour prendre les bonnes décisions dans la vie. Il pourrait ainsi être envisageable d’entrainer les élèves à développer leurs capacités à contourner les biais de raisonnement. Pour ce faire, il faudrait déjà pouvoir mesurer le niveau de rationalité spécifiquement chez les adolescents. Or la mesure de la rationalité n’a que très peu été étudiée à ce jour, et encore moins chez les jeunes. Comme l’inhibition de réactions impulsives permettrait d’avoir un meilleur raisonnement et donc de meilleures capacités en rationalité, il nous paraissait alors intéressant de chercher une corrélation que nous pensions a priori négative entre l’impulsivité et la rationalité chez les adolescents. Notre étude portait sur un échantillon de 141 élèves, filles et garçons de 9-10-11ème des Voies Générale (VG) et Prégymnasiale (VP) et cherchait à valider une version simplifiée de questionnaire pour évaluer le quotient rationnel chez les adolescents, que nous avons élaboré avec des questions adaptées à leur âge et niveau de développement. Le premier but de ce travail était ainsi de créer un questionnaire destiné à des adolescents et d’en tester les qualités psychométriques. Ensuite, nous voulions analyser les scores obtenus par les élèves au questionnaire. Nous avons donc regardé s’il y avait un lien entre le score total obtenu au questionnaire de rationalité et l’âge des élèves qui allait de onze à seize ans. En plus de l’âge, nous avons également cherché un lien entre le score total et la voie scolaire (VG ou VP), le score total et le degré scolaire (9H, 10H ou 11H) et enfin le score total et le sexe (fille ou garçon). Enfin, notre étude cherchait aussi à établir un lien entre la rationalité et l’impulsivité, ce qui a pu être partiellement établi.

description: Applying Grand Unified Theories in the context of the early Universe, cosmic strings are an unavoidable partner of the inflaton field. To render such models compatible with the CMB temperature anisotropies, the inflationary scale has to be lower than the 2x10^{16} GeV value deduced from the tensor-to-scalar ratio announced from the BICEP2 collaboration. Some questions are consequently raised about our understanding of the thermal history of the Universe.

Hilbert-Schmidt Operators vs. Integrable Systems of Elliptic Calogero-Moser Type IV. The Relativistic Heun (van Diejen) Case

description: The 'relativistic' Heun equation is an 8-coupling difference equation that generalizes the 4-coupling Heun differential equation. It can be viewed as the time-independent Schrödinger equation for an analytic difference operator introduced by van Diejen. We study Hilbert space features of this operator and its 'modular partner', based on an in-depth analysis of the eigenvectors of a Hilbert-Schmidt integral operator whose integral kernel has a previously known relation to the two difference operators. With suitable restrictions on the parameters, we show that the commuting difference operators can be promoted to a modular pair of self-adjoint commuting operators, which share their eigenvectors with the integral operator. Various remarkable spectral symmetries and commutativity properties follow from this correspondence. In particular, with couplings varying over a suitable ball in ${\mathbb R}^8$, the discrete spectra of the operator pair are invariant under the $E_8$ Weyl group. The asymptotic behavior of an 8-parameter family of orthonormal polynomials is shown to be shared by the joint eigenvectors.

description: The linear noise approximation models the random fluctuations from the mean-field model of a chemical reaction that unfolds near the thermodynamic limit. Specifically, the fluctuations obey a linear Langevin equation up to order $Ω^{-1/2}$, where $Ω$ is the size of the chemical system (usually the volume). In the presence of disparate timescales, the linear noise approximation admits a quasi-steady-state reduction referred to as the \textit{slow scale} linear noise approximation (ssLNA). Curiously, the ssLNAs reported in the literature are slightly different. The differences in the reported ssLNAs lie at the mathematical heart of the derivation. In this work, we derive the ssLNA directly from geometric singular perturbation theory and explain the origin of the different ssLNAs in the literature. Moreover, we discuss the loss of normal hyperbolicity and we extend the ssLNA derived from geometric singular perturbation theory to a non-classical singularly perturbed problem. In so doing, we disprove a commonly-accepted qualifier for the validity of stochastic quasi-steady-state approximation of the Michaelis--Menten reaction mechanism.

description: Let $w$ denote a weight in $\mathbb{R}^n$ which belongs to the Muckenhoupt class $A_\infty$ and let $\mathsf{M}_w$ denote the uncentered Hardy-Littlewood maximal operator defined with respect to the measure $w(x)dx$. The \emph{sharp Tauberian constant} of $\mathsf M_w$ with respect to $α$, denoted by $\mathsf{C}_w (α)$, is defined by \[ \mathsf{C}_w (α) := \sup_{E:\, 0 < w(E) < \infty}w(E)^{-1}w\big(\big\{x \in \mathbb{R}^n:\, \mathsf{M}_w χ_E (x) > α\big\}\big). \] In this paper, we show that the Solyanik estimate \[ \lim_{α\rightarrow 1^-}\mathsf{C}_w(α) = 1 \] holds. Following the classical theme of weighted norm inequalities we also consider the sharp Tauberian constants defined with respect to the usual uncentered Hardy-Littlewood maximal operator $\mathsf M$ and a weight $w$: \[ \mathsf C ^w (α) := \sup_{E:\, 0 < w(E) < \infty} w(E)^{-1} w\big(\big\{x \in \mathbb R^n:\, \mathsf{M} χ_E (x) > α\big\}\big). \] We show that we have $\lim_{α\to 1^{-}}\mathsf{C}^w(α)=1$ if and only if $w\in A_\infty$. As a corollary of our methods we obtain a quantitative embedding of $A_\infty$ into $A_p$.

description: We study the quantum critical phase of a SU(2) symmetric spin-2 chain obtained from spin-2 bosons in a one-dimensional lattice. We obtain the scaling of the entanglement entropy and finite-size energies by exact diagonalization and density-matrix renormalization group methods. From the numerical results of the energy spectrum, central charge, and scaling dimension we identify the conformal field theory describing the whole critical phase to be the SU(3)$_1$ Wess-Zumino-Witten model. We find that while in the whole critical phase the Hamiltonian is only SU(2) invariant, there is an emergent SU(3) symmetry in the thermodynamic limit.

description: Motivated by recent experimental study of antiferromagnetic property of honeycomb compound In$_{3}$Cu$_{2}$VO$_{9}$ [Yan \textit{et al.}, PRB \textbf{85}, 085102 (2012)], we explore possible superconductivity and its coexistence with antiferromagnetism. We use the t-t$^\prime$-J model on the honeycomb lattice as our starting point and employ the slave-boson mean-field theory. In the antiferromagnetic normal state, the characteristic doping evolution of Fermi surface shows that only one effective singe band is active, which suggests that the potential pairing symmetry is the time-reversal symmetry breaking $d+id$, rather than the extended $s$-wave. It is found that this superconducting state coexists with the antiferromagnetism in a broad doping regime, which is consistent with the numerical calculations. The local density of states and its thermodynamic property of the superconducting state has been studied in detail with an effective single-band picture for understanding other physical observable such as superfluid density. The present work may be useful in experimentally exploring possible superconductivity of this kind of materials on the honeycomb lattice and contributes to the understanding of the unconventional superconductivity on general two-dimensional correlated electron systems.

description: We show that the Lagrangian for Lovelock-Cartan gravity theory can be re-formulated as an action which leads to General Relativity in a certain limit. In odd dimensions the Lagrangian leads to a Chern-Simons theory invariant under the generalized Poincaré algebra $\mathfrak{B}_{2n+1},$ while in even dimensions the Lagrangian leads to a Born-Infeld theory invariant under a subalgebra of the $\mathfrak{B}_{2n+1}$ algebra. It is also shown that torsion may occur explicitly in the Lagrangian leading to new torsional Lagrangians, which are related to the Chern-Pontryagin character for the $B_{2n+1}$ group.

description: The conditions for the validity of the standard quasi-steady-state approximation in the Michaelis--Menten mechanism in a closed reaction vessel have been well studied, but much less so the conditions for the validity of this approximation for the system with substrate inflow. We analyze quasi-steady-state scenarios for the open system attributable to singular perturbations, as well as less restrictive conditions. For both settings we obtain distinguished invariant slow manifolds and time scale estimates, and we highlight the special role of singular perturbation parameters in higher order approximations of slow manifolds. We close the paper with a discussion of distinguished invariant manifolds in the global phase portrait.

description: La spiritualité est un concept propre à chacun qui s’avère être une ressource bénéfique dans la vie quotidienne, mais également lors d’un événement en lien avec la mort. En effet, une spiritualité développée agit sur sa manière de réguler ses émotions, permet de donner un sens aux événements et à mieux accepter la perte d’un être cher. L’école est un lieu de vie qui, lorsque la mort la frappe, doit gérer ce que l’on appelle une situation de crise. L’école, qui était auparavant un lieu de stabilité pour l’élève, devient alors un espace chamboulé où les repères antérieurs sont bouleversés. Ce travail étudie comment la dimension spirituelle peut être inclue dans les activités d’accompagnement des élèves dans une situation de crise. Des entretiens ont été réalisés avec des enseignants de Bruxelles et du Canton de Vaud afin d’identifier les particularités des pratiques enseignantes. Il a également été sondé la perception de la posture enseignante lors de situation de crise en fonction du cadre scolaire et des bases légales de chacun. Finalement, des recommandations sont proposées aux enseignants afin d’inclure au mieux une dimension spirituelle aux activités d’accompagnement des élèves tout en restant conforme à la neutralité demandée par l’école publique.

description: Reversible work extraction from identical quantum systems via collective operations was shown to be possible even without producing entanglement among the sub-parts. Here, we show that implementing such global operations necessarily imply the creation of quantum correlations, as measured by quantum discord. We also reanalyze the conditions under which global transformations outperform local gates as far as maximal work extraction is considered by deriving a necessary and sufficient condition that is based on classical correlations.

description: We consider the bond percolation problem on a transient weighted graph induced by the excursion sets of the Gaussian free field on the corresponding cable system. Owing to the continuity of this setup and the strong Markov property of the field on the one hand, and the links with potential theory for the associated diffusion on the other, we rigorously determine the behavior of various key quantities related to the (near-)critical regime for this model. In particular, our results apply in case the base graph is the three-dimensional cubic lattice. They unveil the values of the associated critical exponents, which are explicit but not mean-field and consistent with predictions from scaling theory below the upper-critical dimension.

Higgs boson decay into two photons in an electromagnetic background

subject: FOS: Physical sciences

description: The amplitude for Higgs boson decay into two photons in a homogeneous and time-independent magnetic field is investigated by proper-time regularization in a gauge invariant manner and is found to be singular at large field values. The singularity is caused by the component of the charged vector boson field that is tachyonic in a strong magnetic field. Also tools for the computation of the amplitude in a more general electromagnetic background are developed.

description: Si l’allemand est une discipline importante du cursus scolaire des élèves du secondaire I en Suisse romande, elle est également mal-aimée. Les approches actuelles de la didactique des langues-cultures étrangères, et en particulier l’approche CLIL d’enseignement par les contenus, ont démontré leur capacité à agir de manière positive sur les dimensions de la motivation à apprendre les langues : la confiance en soi et dans sa capacité à produire la langue et les représentations de la langue et de la communauté linguistique, pour ne citer que celles-ci. De plus, les dernières recherches sur la créativité dans le contexte de l’apprentissage d’une langue ont révélé un fort potentiel à motiver, intéresser et soutenir les apprentissages des élèves. Ce travail a permis de démontrer que des effets positifs sur certaines dimensions de la motivation à apprendre une langue peuvent être obtenus par l’enseignement d’une séquence CLIL mobilisant la créativité des élèves. Cette étude a été menée dans une classe de dixième année. Les participants ont notamment exprimé un intérêt plus grand à apprendre dans les conditions d’une séquence CLIL mobilisant leur créativité et ils ont exprimé avoir apprécié la plus grande liberté dans la réalisation de la tâche et l’utilisation des moyens numériques. Si l’analyse données a démontré qu’avant l’enseignement de la séquence, un certain nombre de conditions favorisant la motivation des élèves à apprendre étaient déjà réunies, notamment un cadre positif et encourageant et l’existence de facteurs de motivation extrinsèque importants, la confiance dans leur capacité à maîtriser la langue et l’intérêt pour la discipline étaient très faibles. Néanmoins, la séquence enseignée a pu accroitre de manière potentiellement significative l’intérêt des élèves.

In a no‐win situation: The employment–health dilemma

description: Work and organizational psychology (WOP) research has to date mostly focused on people privileged to have the choice between several attractive job options and less on people who are restricted in their job choice (e.g., due to their qualification or personal contingencies) and have to choose from fewer and often less-than-optimal jobs. Often, the jobs available to the latter are characterized by precarious employment and hazardous working conditions which can put them in the difficult situation of having to choose between a health-threatening job and possible unemployment. Building on interdisciplinary literature, we propose the employment–health dilemma (E-H dilemma) as a framework for analyzing this intrapersonal conflict of having to choose between employment (incurring health threats) and health (incurring economic threats) and discuss potential antecedents and consequences of the E-H dilemma at the societal, organizational, and individual level. We outline the implications of the E-H dilemma and make a case for examining the full spectrum of job choice situations in WOP research. In doing so, we demonstrate what WOP can gain by embracing a more inclusive and multidisciplinary approach: uncovering processes in their entirety (e.g., job choice decisions of all people) and strengthening the role and legitimacy of WOP in society.
Estimation of CO$_2$ flux from targeted satellite observations: a Bayesian approach
Creators: name: Cox, Graham
Publisher: name: arXiv
Year: 2014
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: We consider the estimation of carbon dioxide flux at the ocean-atmosphere interface, given weighted averages of the mixing ratio in a vertical atmospheric column. In particular we examine the dependence of the posterior covariance on the weighting function used in taking observations, motivated by the fact that this function is instrument-dependent, hence one needs the ability to compare different weights. The estimation problem is considered using a variational data assimilation method, which is shown to admit an equivalent infinite-dimensional Bayesian formulation. The main tool in our investigation is an explicit formula for the posterior covariance in terms of the prior covariance and observation operator. Using this formula, we compare weighting functions concentrated near the surface of the earth with those concentrated near the top of the atmosphere, in terms of the resulting covariance operators. We also consider the problem of observational targeting, and ask if it is possible to reduce the covariance in a prescribed direction through an appropriate choice of weighting function. We find that this is not the case---there exist directions in which one can never gain information, regardless of the choice of weight.

The proton-deuteron system in pionless EFT revisited

description: We provide a detailed discussion of the low-energy proton-deuteron system in pionless effective field theory, considering both the spin-quartet and doublet S-wave channels. Extending and amending our previous work on the subject, we calculate the 3He-3H binding energy difference both perturbatively (using properly normalized trinucleon wave functions) and non-perturbatively by resumming all O(alpha) Coulomb diagrams in the doublet channel. Our nonperturbative result agrees well with a calculation that involves the full off-shell Coulomb T-matrix. Carefully examining the cutoff-dependence in the doublet channel, we present numerical evidence for a new three-nucleon counterterm being necessary at next-to-leading order if Coulomb effects are included. Indeed, such a term has recently been identified analytically. We furthermore make a case for a simplified Coulomb power counting that is consistent throughout the bound-state and scattering regimes. Finally, using a "partially screened" full off-shell Coulomb T-matrix, we investigate the importance of higher-order Coulomb corrections in low-energy quartet-channel scattering.

description: Que ce soit en perturbant l’apprentissage, en mettant en danger la sécurité physique et/ou psychologique de l’élève lui-même et/ou celle des autres, les comportements d’indiscipline vont à l’encontre des règles assurant le bon fonctionnement au sein d’une classe. Étant un des problèmes majeurs dans le système scolaire, ce sujet interpelle depuis de nombreuses années et maintes recherches ont voulu en apprendre plus afin d’y remédier. En effet, non loin d’être un sujet récent, ce phénomène est malheureusement et souvent accompagné de conséquences pouvant aller, pour l’élève, du mauvais rendement au décrochage scolaire. En ce qui concerne les enseignants, des sentiments comme la frustration ou l’épuisement peuvent les amener jusqu’au burnout. Il est alors important de pouvoir trouver des solutions afin d’améliorer l’expérience de l’élève et de l’enseignant à l’école. Ces problèmes peuvent en effet être réglés à court terme via le système des sanctions, mais si la source de ces comportements reste méconnue, ils réapparaîtront tôt ou tard. Notre expérience du métier nous a conduit à supposer qu’il existait, au sein des partenaires de l’institution scolaire, différents niveaux de perception de gravité des comportements d’indiscipline qui pourraient expliquer la cause de leur existence et persistance. Aussi, dans ce travail de Master nous avons cherché à comprendre comment étaient perçus les comportements d’indiscipline au sein des établissements scolaires du secondaire I. Notre étude, réalisée dans deux établissements secondaires du canton de Vaud et basée sur une démarche à la fois hypothético-déductive et inductive, nous a permis de relever des éléments répondant à notre question de recherche, mais également de valider ou réfuter nos hypothèses de départ. En constatant qu’il existe bel et bien des différences de perception entre les enseignants et les élèves, au sein des enseignants ainsi qu’au sein des élèves, nous émettons l’hypothèse qu’un manque de compréhension entre les différents individus d’une même institution pourrait engendrer des dysfonctionnements. Tout ceci conforte notre suspicion quant à l’importance de la communication entre l’enseignant et l’élève, une des clés pour couper le problème directement à la racine.
