description: The requirement of manifest gauge invariance leads to a conflict between perturbative and non-perturbative predictions for the low-energy spectra of grand-unified theories. These conflicts already emerge in simplified prototype models of SU(3) gauge theories with Higgs fields in different representations. We expand earlier lattice investigations on this subject and provide further support for the predicted deviations. These can be understood in terms of the Froehlich-Morchio-Strocchi mechanism.

description: Ce travail porte sur l'importance de la pratique expérimentale dans l'enseignement des sciences. Par pratique nous entendons courtes démonstrations en classe réalisées par l’enseignant ou travail pratique réalisé par les élèves en laboratoire. Nous avons tout d'abord cherché à comprendre comment et pourquoi nos prédécesseurs en sont arrivés à faire de la pratique expérimentale dans l'enseignement des sciences. Nous avons également interrogé notre entourage, indépendamment de s'ils avaient reçu un enseignement scientifique et de s'ils avaient continué dans l'étude des sciences. Nous nous sommes ensuite intéressées au rapport au savoir des élèves vis-à-vis de l'école et en quoila pratique pouvait ou non les soutenir dans la compréhension de concepts chimiques et/ou physiques. Ce qui ressort d'un questionnaire distribué à nos élèves est que ces derniers sont très favorables à l'emploi de la pratique. L'analyse des réponses nous a permis de conclure que la réalisation d'expérience en classe, par l'enseignant, aide à la compréhension des phénomènes physiques et chimiques et peut se faire avant ou après avoir vu la théorie. Si c'est avant, elle va servir de base de questionnement et si c'est après elle va servir de terreau dans lequel l'élève pourra puiser pour se souvenir de la théorie. La longueur et la difficulté des TP stressent parfois les élèves, qui cherchent à suivre le protocole pas à pas. Ce fait souligne l'importance de la clarté de l'objectif, par laquelle on pourra guider les élèves vers un questionnement sur ce qui est attendu d'eux, à savoir l'augmentation de leurs connaissances. La plupart de nos TP sont avec protocole. Une démarche qui pourrait les aider à mieux réaliser ce qu'ils doivent apprendre est un approche hypothetico déductive, durant laquelle ce sont les élèves qui posent une/des hypothèses à vérifier à l'aide d'expériences montées par eux-mêmes.

description: We prove that any length metric space homeomorphic to a 2-manifold with boundary, also called a length surface, is the Gromov-Hausdorff limit of polyhedral surfaces with controlled geometry. As an application, using the classical uniformization theorem for Riemann surfaces and a limiting argument, we establish a general "one-sided" quasiconformal uniformization theorem for length surfaces with locally finite Hausdorff 2-measure. Our approach yields a new proof of the Bonk-Kleiner theorem characterizing Ahlfors 2-regular quasispheres.

description: We use long-run, high-resolution hydrodynamics simulations to compute the multi-wavelength light curves (LCs) from thermal disk emission around accreting equal-mass supermassive black hole (BH) binaries, with a focus on revealing binary eccentricity. LCs are obtained by modeling the disk thermodynamics with an adiabatic equation of state, a local blackbody cooling prescription, and corrections to approximate the effects of radiation pressure. We find that modulation of multi-band LCs on the orbital time scale are generally in-phase (to within $\sim\,$2% of a binary orbital period), but they contain pulse substructure in the time domain that is not necessarily reflected in BH accretion rates $\dot M$. We thus predict that binary-hosting AGN will exhibit highly correlated, in-phase, periodic brightness modulations in their low-energy disk emission. However, detectability of these modulations in multi-wavelength observing campaigns could be seriously compromised because observed stochastic variability in AGNs typically has a higher amplitude than our proposed signal. It is possible that observations over temporal baselines of many binary periods may make the signal more prominent, but this would need to be analyzed carefully. If jet emission is predicted by $\dot{M}$, then we predict a weaker correlation with low-energy disk emission due to the differing sub-peak structure. For the binary parameters we explore, we show that LC variability due to hydrodynamics likely dominates Doppler brightening for all equal-mass binaries with disk Mach numbers $\lesssim 20$. A promising signature of eccentricity is weak or absent "lump" periodicity. We find hints that a significant lag exists between $\dot{M}$ and low-energy disk emission for circular binaries, but they are in-phase for eccentric binaries, which might explain some "orphan" blazar flares with no $γ$-ray counterpart.

description: On recherche sans cesse des moyens d’améliorer l’apprentissage des langues étrangères. Or, toutes les langues n’ont pas le même statut informel pour les apprenants, elles ne les motivent pas tous de la même manière. Ce statut, en effet, peut influencer et affecter les performances en général de l’étudiant. Suite à ce constat et après analyse du cas de l’espagnol langue étrangère dans le Canton de Vaud, nous nous sommes demandés si l’approche interculturelle ne pourrait pas être une aide pour moduler cette image et par là même obtenir de meilleurs résultats d’apprentissages. C’est pourquoi dans ce travail, nous proposons tout d’abord une définition de l’interculturalité au sens général dans les sciences sociales, pour nous centrer ensuite sur son approche pédagogique concrète dans l’enseignement des langues étrangères et notamment la pratique de la compétence interculturelle qui complète la compétence de communication. Nous donnerons ensuite quelques outils officiels indispensables pour concevoir des tâches interculturelles en espagnol pour des étudiants du secondaire II et nous terminerons par l’analyse de trois d’entre elles créés pour nos classes du gymnase durant notre stage. Cette dernière partie, nous amènera à voir quels sont véritablement les enjeux de l’interculturalité pour notre questionnement de base, mais nous permettra aussi d’ouvrir ces enjeux à l’enseignement en général. En effet, l’approche interculturelle fait partie plus largement des approches plurielles dont les objectifs se trouvent dans un projet de former des étudiants critiques, interculturels, libres et capables d’aborder un Autre dans un esprit positif. Participer à ce projet en classe de langues étrangères nous a semblé un enjeu qui se complète bien à notre souci d’améliorer l’apprentissage chez nos apprenants.

description: We announce a new facility in the spectral code CLOUDY that enables tracking the evolution of a cooling parcel of gas with time. For gas cooling from temperatures relevant to galaxy clusters, earlier calculations estimated the [Fe XIV] λ5303 / [Fe X] λ6375 luminosity ratio, a critical diagnostic of a cooling plasma, to slightly less than unity. By contrast, our calculations predict a ratio ~3. We revisit recent optical coronal line observations along the X-ray cool arc around NGC 4696 by Canning et al. (2011), which detected [Fe X] λ6375, but not [Fe XIV] λ5303. We show that these observations are not consistent with predictions of cooling flow models. Differential extinction could in principle account for the observations, but it requires extinction levels (A_V > 3.625) incompatible with previous observations. The non-detection of [Fe XIV] implies a temperature ceiling of 2.1 million K. Assuming cylindrical geometry and transonic turbulent pressure support, we estimate the gas mass at ~1 million solar masses. The coronal gas is cooling isochorically. We propose that the coronal gas has not condensed out of the intracluster medium, but instead is the conductive or mixing interface between the X-ray plume and the optical filaments. We present a number of emission lines that may be pursued to test this hypothesis and constrain the amount of intermediate temperature gas in the system.

description: Transfer Optimization has gained a remarkable attention from the Swarm and Evolutionary Computation community in the recent years. It is undeniable that the concepts underlying Transfer Optimization are formulated on solid grounds. However, evidences observed in recent contributions confirm that there are critical aspects that are not properly addressed to date. This short communication aims to engage the readership around a reflection on these issues, and to provide rationale why they remain unsolved. Specifically, we emphasize on three critical points of Evolutionary Multitasking Optimization: i) the plausibility and practical applicability of this paradigm; ii) the novelty of some proposed multitasking methods; and iii) the methodologies used for evaluating newly proposed multitasking algorithms. As a result of this research, we conclude that some important efforts should be directed by the community in order to keep the future of this promising field on the right track. Our ultimate purpose is to unveil gaps in the current literature, so that prospective works can attempt to fix these gaps, avoiding to stumble on the same stones and eventually achieve valuable advances in the area.

description: Tea is a widely consumed and trendy beverage worldwide. All tea is derived from the leaves of the Camellia sinensis, which belongs to the Theaceae family. Throughout the years, various teas have displayed health benefits after human consumption, with green tea, in particular, attracting popularity. However, purple tea (Camellia sinensis var. assamica cv. Zijuan), which has yet to be investigated, has become of recent interest due to the many bioactivities it has displayed, including antioxidant and anti-inflammatory attributed to the phenolic compounds, especially flavanols. The use of purple tea in food models has not yet been completed hence the aims of this study were to optimise the extraction of phenolic compounds by ultrasound-assisted extraction (UAE), assess the antioxidant effects and composition of the purple tea extract (OPM), and determine its antioxidant capacity potential in milky teas containing microencapsulated OPM. OPM had a total phenolic content (TPC) of 331 mg/g, where (-)-epigallocatechin gallate was the main compound (50 mg/g). OPM showed antioxidant capacity using different test tube-based assays, decreased reactive oxygen species (ROS) generation and formation of thiobarbituric acid reactive substances (TBARS) in human erythrocytes, and decreased the formation of oxidised products (i.e., dienes) in human plasma. Additionally, OPM was able to significantly inhibit α-glucosidase (IC50 = 23.0 μg/mL) and α-amylase (IC50 = 12.4 μg/mL), and did not show significant inhibition (e.g., <70% viability) of murine astrocyte’s viability at 0.01 – 0.2 mg/mL. Milky teas containing OPM had a TPC of 561 mg/L, a content 4.5-fold greater than a standard commercial milky tea. This is the first report using microencapsulation technology as a delivery system to develop potentially functional milky teas with added polyphenol-rich extract from purple tea leaves.

description: Quantum chemical calculations on quantum computers have been focused mostly on simulating molecules in gas-phase. Molecules in liquid solution are however most relevant for Chemistry. Continuum solvation models represent a good compromise between computational affordability and accuracy in describing solvation effects within a quantum chemical description of solute molecules. Here we report on the extension of the Variational Quantum Eigensolver to solvated systems, using the Polarizable Continuum Model. We show that accounting for solvation effects does not impact the algorithmic efficiency. Numerical results of noiseless simulations for molecular systems with up to twelve spin-orbitals (qubits) are presented. Furthermore, calculations performed on a simulated quantum hardware (IBM Q Mumbai), thus including noise, yield computed solvation free energies in fair agreement with the classical calculations without the inclusion of any error mitigation protocol.

description: La infección por el virus de inmunodeficiencia humana (VIH) es un problema de salud pública a nivel mundial solamente en México en el año 2017, se reportaron 5670 casos nuevos, Baja California ocupando el 6to lugar a nivel nacional. los cuales se encuentran en riesgo de desarrollar trastorno neurocognoscitivo mayor (CENSIDA, 2018). Se ha descrito una relación de síntomas neurológicos en 10% de los pacientes, y complicaciones neurológicas hasta en un 30% durante el curso de la enfermedad (Sonkar et al., 2012), uno de estos es el trastorno neurocognoscitivo asociados al VIH (HAND), la cual es una condición progresiva incapacitante caracterizada por demencia subcortical que se manifiesta con disminución de atención y concentración, compromiso motor y alteraciones en el comportamiento variables lo que culmina en muerte dentro de 1 año en promedio. Se asocia con atrofia. La prevalencia ha disminuido con el advenimiento de la terapia antiretroviral altamente activa. La variabilidad en cuanto a prevalencia varía mucho ya que no se realizan cotidianamente estudios para el abordaje de trastorno neurocognoscitivo. Los factores de riesgo que se asocian principalmente son: la edad mayor a 50 años, conteo de CD4+ menor a 200 por mililitro, carga viral >50 copias por mililitro; factores de riesgo cardiovascular; la coinfección por virus de la hepatitis C, el uso de drogas ilícitas, trastorno de ansiedad generalizado, depresión, alcoholismo, historia de traumatismo craneoencefálico y mala adherencia al tratamiento (Clifford & Ances, 2013; Saylor et al., 2016). El diagnóstico es puramente clínico y no existe tratamiento específico. En el año 2005 Sacktor, et al, publican la escala internacional para demencia asociada a VIH (IHDS), la cual se realizó en 81 pacientes con VIH de estados unidos y 66 pacientes con VIH en Uganda la cual reporta una sensibilidad que varía del 57-80% y una especificidad del 55-80% en esas poblaciones, tomando un punto de cohorte menor a 10 puntos y actualmente ya se encuentra validada a nivel mundial.

Durant ce travail, nous avons dressé un bilan de ce qui existe dans ce domaine en Suisse romande, mais aussi à l'étranger au niveau francophone. Pour ce faire, nous avons sélectionné un échantillon aussi représentatif que possible de sites présentant des approches particulière à la mutualisation de ressources numériques pour l'enseignement. Nous avons détaillé ces différentes plate-formes et avons tenté d'en résumer les principales caractéristiques et de comprendre ce qu'elles apportaient d'original dans le domaine. Pour ce faire, nous les avons comparées nous-mêmes, mais nous nous sommes également basés sur des avis recueillis auprès de certains de leurs créateurs. Nous avons conclu, en nous basant sur des critères tels que la fréquentation, le nombre d’inscriptions, le nombre de documents disponibles, la présence de certaines fonctionnalités (exemple : forums de discussion, système de commentaire), que la plate-forme qui semble le mieux convenir aux enseignants de manière général est www.enseignons.be, bien qu'elle ne soit pas directement en lien avec le plan d'étude romand, comme peuvent l'être certaines plate-formes romandes également prometteuses comme enseignement.educa.ch ou extranet.hepl.ch/bddp/. Nous avons pu également constater, grâce à des conversations entretenues avec nos collègues au sujet de ces plate-formes, que la plupart de celles-ci restent encore largement méconnues des enseignants romands. Notre principale piste pour remédier à ce problème serait d'inclure ce nouvel aspect de l'enseignement dans les cursus de formation HEP afin qu'au moins les nouveaux enseignants en soient informés.

description: Recent numerical studies of the coupled Einstein-Klein-Gordon system in a cavity have provided compelling evidence that {\it confined} scalar fields generically collapse to form black holes. Motivated by this intriguing discovery, we here use analytical tools in order to study the characteristic resonance spectra of the confined fields. These discrete resonant frequencies are expected to dominate the late-time dynamics of the coupled black-hole-field-cage system. We consider caged Reissner-Nordström black holes whose confining mirrors are placed in the near-horizon region $x_{\text{m}}\equiv (r_{\text{m}}-r_+)/r_+\llτ\equiv (r_+-r_-)/r_+$ (here $r_{\text{m}}$ is the radius of the confining mirror and $r_{\pm}$ are the radii of the black-hole horizons). We obtain a simple analytical expression for the fundamental quasinormal resonances of the coupled black-hole-field-cage system: $ω_n=-i2πT_{\text{BH}}\cdot n[1+O(x^n_{\text{m}}/τ^n)]$, where $T_{\text{BH}}$ is the temperature of the caged black hole and $n=1,2,3,...$ is the resonance parameter.

Common Agricultural Policy

description: Policy Briefing #22 (v1) collates the definitions of agroforestry included by all Member States in their CAP Strategic Plans.  Some are detailed and include minimum and maximum numbers of trees per hectare, but usually without a definition of “tree”.   Few of the definitions can lead to remotely-sensed identification of those parcels which are “agroforestry” and those which have too few trees to be considered as agroforestry.  Nevertheless, Member States are progressively adding more detail to their identification of "landscape features and non productive areas" (GAEC-8) in their CAP Land Parcel Identification Systems. This detail is also needed to measure compliance with the 10% target in the Biodiversity Strategy and draft Nature Restoration Law (see Briefings #18 and  #21).  It is therefore possible for  Member States to propose a % threshold tree-crown cover (actual or potential) which can be used to distinguish agroforestry parcels in the CAP, The same classification can be used  for GHG accounting to the UNFCCC.  Several Member States have taken advantage of the flexibility offered in the Strategic Plan Regulation to define “permanent grassland” to include areas which are predominantly covered by shrubs which can be grazed or cut for fodder (See Briefing #29).  These include areas which can also be considered as agroforestry.

description: We consider macroscopic systems in weak contact with boundary reservoirs and under the action of external fields. We present an explicit formula for the Hamiltonian of such systems, from which we deduce the equation of motions, the action functional, the hydrodynamic equation for the adjoint dynamics, and a formula for the quasi-potential. We examine the case in which the external forcing depends on time and drives the system from one nonequilibrium state to another. We extend the results presented in [6] on thermodynamic transformations for systems in strong contact with boundary reservoirs to the present situation. In particular, we propose a natural definition of renormalized work, and show that it satisfies a Clausius inequality, and that quasi-static transformations minimize the renormalized work. In addition, we connect the renormalized work to the quasi-potential describing the fluctuations in the stationary nonequilibrium ensemble.

description: Entanglement in quantum many-body systems is the key concept for future technology and science, opening up a possibility to explore uncharted realms in an enormously large Hilbert space. The hybrid quantum-classical algorithms have been suggested to control quantum entanglement of many-body systems, and yet their applicability is intrinsically limited by the numbers of qubits and quantum operations. Here we propose a theory which overcomes the limitations by combining advantages of the hybrid algorithms and the standard mean-field-theory in condensed matter physics, named as mean-operator-theory. We demonstrate that the number of quantum operations to prepare an entangled target many-body state such as symmetry-protected-topological states is significantly reduced by introducing a mean-operator. We also show that a class of mean-operators is expressed as time-evolution operators and our theory is directly applicable to quantum simulations with $^{87}$Rb neutral atoms or trapped $^{40}$Ca$^+$ ions.

We describe a new $^3$He-$^{129}$Xe co-magnetometer probed by Rb atoms and use it to identify two general classes of systematic effects in gas co-magnetometers, one associated with diffusion in second-order magnetic field gradients and another due to temperature gradients. We also develop a general and practical approach for calculating spin relaxation and frequency shifts due to arbitrary magnetic field gradients and confirm it experimentally.

description: Using broadband (12-45 THz) multi-terahertz spectroscopy, we show that stimulated Rayleigh scattering dominates the transient optical conductivity of cadmium arsenide, a Dirac semimetal, under an optical driving field at 30 THz. The characteristic dispersive lineshape with net optical gain is accounted for by optical transitions between light-induced Floquet subbands, strikingly enhanced by the longitudinal plasma mode. Stimulated Rayleigh scattering with an unprecedentedly large refractive index change may pave the way for slow light generation in conductive solids at room temperature.

We compare our new observations to high-resolution, high signal-to-noise archival data from 2001, allowing a unique investigation into the long-term variations of the absorption over a 12 yr period. We find no statistically significant changes in the physical properties of the X-ray absorber, but there is a significant drop of ~40% in the UV and X-ray flux, and a significant flattening of the underlying X-ray power-law slope. Large kinematic changes are seen in the UV absorbers, possibly due to radial deceleration of the material. Similar behavior is not observed in the X-ray data, likely due to its lower velocity resolution, which shows an outflow velocity of v ~ -655 km/s in both epochs. The narrow iron K-alpha emission line at 6.4 keV shows no variation between epochs, and its measured width places the material producing the line at a radial distance of ~0.03 pc from the central black hole.

description: The $p$-widths of a closed Riemannian manifold are a nonlinear analogue of the spectrum of its Laplace--Beltrami operator, which corresponds to areas of a certain min-max sequence of possibly singular minimal submanifolds. We show that the $p$-widths of any closed Riemannian two-manifold correspond to a union of closed immersed geodesics, rather than simply geodesic nets. We then prove optimality of the sweepouts of the round two-sphere constructed from the zero set of homogeneous polynomials, showing that the $p$-widths of the round sphere are attained by $\lfloor \sqrt{p}\rfloor$ great circles. As a result, we find the universal constant in the Liokumovich--Marques--Neves--Weyl law for surfaces to be $\sqrtπ$. En route to calculating the $p$-widths of the round two-sphere, we prove two additional new results: a bumpy metrics theorem for stationary geodesic nets with fixed edge lengths, and that, generically, stationary geodesic nets with bounded mass and bounded singular set have Lusternik--Schnirelmann category zero.

description: L’objectif de ce mémoire est de faire le point sur les mesures d’accueil des stagiaires et jeunes enseignants dans les écoles professionnelles du canton de Vaud. Ainsi, l’analyse porte sur les points suivants : Le programme d’établissement est un document dont l’élaboration est imposée par le service d’éducation physique et du sport. Pour le jeune maître d’éducation physique, ce dernier constitue un fil conducteur et lui donne un cadre de travail. La premier point d’intérêt de ce mémoire est celui-ci : Existe-t-il un programme d’établissement type dans les EP vaudoises ? Si oui, quelles en sont ses particularités et est-il adapté aux besoins des stagiaires/nouveaux maîtres d’éducation physique ? Les mesures d’accueil dans les établissements du canton font objet de la deuxième partie. L’expérience dans certaines écoles professionnelles du canton démontre que l’accompagnement des nouveaux enseignants durant la première année de travail conduit à une meilleure intégration au sein de l’établissement. Le mémoire étudie en quoi consiste un tel accompagnement et « coaching ». Aussi, nous nous posons la question de savoir quelles méthodes sont appliquées dans les écoles professionnelles du canton. Finalement, nous déterminerons si on peut repérer des différences entre des établissements qui pratiquent le« coaching » et ceux qui n’adoptent aucune mesure particulière. Le regard est porté particulièrement sur le Centre professionnel du Nord vaudois, qui occupe un rôle de précurseur dans notre champ d’étude. La mise en œuvre du cadre légal, ainsi que l’utilité des procédures d’accueil des jeunes maîtres d’éducation physique dans les écoles professionnelles sont vérifiées à travers un questionnaire conçu dans ce but. L’analyse de ce dernier permet d’examiner l’adéquation du bagage académique des futurs enseignants de sport avec l’apport de la formation pédagogique (pour les défis quotidiens en salle de sport.) Le mémoire propose des réponses possibles à la question, comment faciliter le travail des stagiaires et nouveaux maîtres d’éducation physique? et donne des pistes, pouvant êtres utilisées par les directions des écoles professionnelles.

The Dual of a Tidal Force in the D1D5 CFT
Creators: name: Guo, Bin
name: Hampton, Shaun
Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: It was demonstrated that a string probe falling radially within a superstratum geometry would experience tidal forces. These tidal forces were shown to excite the string by converting its kinetic energy into stringy excitations. Using the AdS/CFT correspondence we seek to understand this behavior from the perspective of the dual D1D5 CFT. To study this process we turn on an interaction of the theory which is described by a deformation operator. We start with an initial state which is dual to a graviton probe moving within the superstratum geometry. We then use two deformation operators to compute transition amplitudes between this state and a final state that corresponds to stringy excitations. We show that this amplitude grows as $t^2$ with $t$ being the amount of time for which the deformation operators are turned on. We argue that this process in the CFT is suggestive of the tidal effects experienced by the probe propagating within the dual superstratum geometry.

description: Previous band structure calculations predicted Ag3AuSe2 to be a semiconductor with a band gap of approximately 1 eV. Here, we report single crystal growth of Ag3AuSe2 and its transport and optical properties. Single crystals of Ag3AuSe2 were synthesized by slow-cooling from the melt, and grain sizes were confirmed to be greater than 2 mm using electron backscatter diffraction. Optical and transport measurements reveal that Ag3AuSe2 is a highly resistive semiconductor with a band gap of and activation energy around 0.3 eV. Our first-principles calculations show that the experimentally-determined band gap lies between the predicted band gaps from GGA and hybrid functionals. We predict band inversion to be possible by applying tensile strain. The sensitivity of the gap to Ag/Au ordering, chemical substitution, and heat treatment merit further investigation.

description: This paper is devoted to the rigorous study of the low temperature properties of the two-dimensional weakly interacting Hubbard model on the honeycomb lattice in which the renormalized chemical potential $μ$ has been fixed such that the Fermi surface consists of a set of exact triangles. Using renormalization group analysis around the Fermi surface, we prove that this model is {\it not} a Fermi liquid in the mathematically precise sense of Salmhofer. The main result is proved in two steps. First we prove that the perturbation series for Schwinger functions as well as the self-energy function have non-zero radius of convergence when the temperature $T$ is above an exponentially small value, namely ${T_0\sim \exp{(-C|λ|^{-1/2})}}$. Then we prove the necessary lower bound for second derivatives of self-energy w.r.t. the external momentum and achieve the proof.

description: Dans les branches d'expression telles que les arts visuels, l'évaluation apparaît complexe. En effet, au vu de l'évolution de cet enseignement, il ne s'agit plus uniquement d'apprécier des compétences techniques, mais également de juger la part expressive des réalisations des élèves. Dans un domaine où la subjectivité est omniprésente, l'impartialité du professeur d'arts visuels dans cette tâche évaluative peut devenir une préoccupation. Une question se pose alors : Comment évaluer le plus objectivement possible une production artistique ? Partant de cette thématique quelque peu épineuse, ce présent mémoire professionnel aborde dans un premier temps les concepts théoriques liés à l'élaboration d'une grille critériée et approfondit la notion de subjectivité ainsi que certains biais de jugement possibles lors du processus d'évaluation. Dans un deuxième temps, cette recherche propose de mettre en pratique ces éléments à travers la construction d'une séquence d'enseignement complète, puis de poser un regard analytique sur le déroulement de celle-ci et de son évaluation. Aussi, l'objectif principal de ce travail n'est pas uniquement la construction d'un cours et d'une grille d'évaluation pertinente. Avant tout, il s'agit ici de rendre compte d'une démarche et de soulever certains aspects problématiques liés à l'évaluation en arts visuels.
