description: Der Bunker „Valentin” ist die Ruine einer U-Boot-Werft der deutschen Kriegsmarine aus dem Zweiten Weltkrieg. In den Jahren 1943–1945 wurden hier Tausende von Zwangsarbeiter*innen aus ganz Europa eingesetzt. Bis zu 1.600 von ihnen starben während der Bauarbeiten an Unterernährung, Krankheiten und willkürlichen Tötungen. 2011 begann die Umgestaltung des Geländes zum „Denkort Bunker Valentin“ in der Trägerschaft der Landeszentrale für politische Bildung Bremen. Die didaktische Arbeit und die Informationsangebote zielen darauf ab, den ursprünglichen Zusammenhang zu Zwangsarbeit und nationalsozialistischem Lagersystem wieder sichtbar zu machen und den Bunker als das wieder zu zeigen, was er ist: ein Tatort. Dabei spielt das Konzept der „forensischen Pädagogik“ eine zentrale Rolle: Die baulichen und materiellen Überreste der ehemaligen Konzentrationslager und der heutigen Gedenkstätten dienen als Beweise für die nationalsozialistischen Gewaltverbrechen, die dort stattgefunden haben.

description: Autism Spectrum Disorder (ASD) represents a collection of developmental conditions whose outward behavioral manifestation defies a single neurological or genetic source. ASD presents a diagnostic ratio of 5:1 boys vs. girls, is associated with altered brain connectivity, and linked to ~1,000 genetic loci and ~400 genes. This study, as part of the National Institutes of Health (NIH) Autism Center of Excellence (ACE) Program, explored each of these domains and their interactions via comprehensive phenomic assessment, structural and connectomic human neuroimaging, and DNA sequencing to identify the sources of sex-specificity in ASD vs. Typically Developing (TD) children. A formal neuropsychological battery was administered to each subject (N=226), including sub-scales from: the DAS, Vineland, SRS, CELF, RBSR, SCQ, BRIEF, and CBCL. T1, EPI, and DWI neuroimaging were acquired on a Siemens 3T Magnetom TrioTim or PRISMA scanners via standardized acquisition protocols. Image preprocessing was performed using FSL, FreeSurfer 7.0, and fit to the atlas of Destrieux et al. Connectivity metrics were computed using DSI Studio and NetworkX. Connectograms, describing average morphometry and connectivity in each group, were computed. DNA sequencing (Illumina Infinium Omni2.5-8 Kit) was performed and compared against the 1,000 Genomes reference. Chromosomes were windowed into 10,000 segments, used to compute mutation densities, and pooled by group where sex-specific differences were statistically identified. Multivariate phenomic diagnosis-by-sex interaction, driven largely by assessment subscales of executive function and self-control, suggests that these cognitive domains may be particularly sensitive to sex-differences in ASD unlike in TD children. No volumetric differences in cortical morphometry were observed. Differences in network theoretical metrics of functional connectivity, however, were present and necessitate further exploration. Gene loci previously linked to ASD, show variable mutation rates by sex, suggestive of differential genetic influences. These results supported the contention that ASD is particularly sexual dimorphic which may hinder effective diagnosis.

description: A subset of a group is characteristic if it is invariant under every automorphism of the group. We study word length in fundamental groups of closed hyperbolic surfaces with respect to characteristic generating sets consisting of a finite union of orbits of the automorphism group, and show that the translation length of any element with nonzero crossing number is positive, and bounded below by a constant depending only (and explicitly) on a bound on the crossing numbers of generating elements. This answers a question of B. Farb.

description: Der Idsteiner Kalmenhof im südhessischen Idstein war zwischen 1939 und 1945 im Rahmen des NS- Euthanasieprogramms Tatort für die Morde an über 700 Kindern, Jugendlichen und Erwachsenen. Bislang wird vermutet, dass etwa die Hälfte der Opfer auf dem Gelände hinter dem anstaltseigenen Krankenhaus verscharrt wurden. Ein Teil des Geländes ist seit den 1980er Jahren als Gedenkstätte ausgewiesen, wobei die genaue Anzahl und Lage der tatsächlich vorhandenen Bestattungen bis heute ungeklärt ist. Aufgrund historischer Quellen lag der Verdacht nahe, dass auch auf angrenzenden Privatgrundstücken mit der Existenz von Opfergräbern zu rechnen sein könnte. Im Rahmen einer interdisziplinär durchgeführten Untersuchung konnten 2020 erste Ergebnisse zur Klärung der vor Ort bestehenden Fragen gewonnen werden.
The skilled helper for Christians : an outcome study on empathy
Creators: name: Ducklow, Carole Anne
Publisher: name: University of British Columbia
Year: 2010

description: This study was conducted to research any increase in empathic discrimination resulting from an empathy training program for paraprofessional Christian counsellors entitled, The Skilled Helper for Christians. There were 13 male and 23 female subjects with a mean age of 38.9 years in the Experimental Group. The two control groups used were similar to the Experimental Group in mean age, gender and Christian faith. The first Control Group, those students enrolled in a course entitled Building Strong Marriages in the Local Church, was made up of 8 male and 8 female students, with a mean age of 38.9 years. The second Control Group consisted of graduate theological students who attended Introduction to Christian Counselling. There were 22 male and 11 female subjects with a mean age of 33.4 years. A pretest-posttest design was used, adapting two instruments based on the Truax Accurate Empathy Scale. The dependent variable was the empathy score attained on each measure. Four null hyotheses were advanced. Both instruments, the Questionnaire in Helpful Responding and the Exercises in Caring and Understanding, were initially analyzed using dependent t-tests. An analysis of covariance and a Tukey multiple comparison were also used. The findings indicated that a significant increase in empathic discrimination resulted from the Skilled Helper for Christians, as measured by the Questionnaire in Helpful Responding. Each Control Group also indicated an increase as measured by the Questionnaire in Helpful Responding, however at a less significant level. The second measure, the Exercises in Caring and Understanding, resulted in no significant increase for any of the groups. Thus, the Skilled Helper for Christians produced a significant gain in empathic discrimination. Other findings suggested that modeling empathy may have had a positive effect on all of the groups.

description: We construct the scalar and graviton propagator in quasi de Sitter space up to first order in the slow roll parameter $ε\equiv -\dot{H}/H^2$. After a rescaling, the propagators are similar to those in de Sitter space with an $ε$ correction to the effective mass. The limit $ε\to 0$ corresponds to the E(3) vacuum that breaks de Sitter symmetry, but does not break spatial isotropy and homogeneity. The new propagators allow for a self-consistent, dynamical study of quantum back-reaction effects during inflation.

description: This paper builds a general framework in which to study cohomology theories of strongly homotopy algebras, namely $A_\infty, C_\infty$ and $L_\infty$-algebras. This framework is based on noncommutative geometry as expounded by Connes and Kontsevich. The developed machinery is then used to establish a general form of Hodge decomposition of Hochschild and cyclic cohomology of $C_\infty$-algebras. This generalizes and puts in a conceptual framework previous work by Loday and Gerstenhaber-Schack.

The seesaw mechanism and discrete $A_4$ symmetry are introduced into the model to understand why neutrinos are especially light and the observed pattern of neutrino mixing. The model provides a method for obtaining the tri-bimaximal mixing matrix in the leading order. A non-zero mixing angle $V_{e3}$ presents in the modified mixing matrix.

We reveal that this equivalence holds if the initial state of the bath can be mapped to a Gaussian phase-space distribution function. Moreover, we discuss the relation to the standard Bloch-Redfield approach.

description: We demonstrate an integral gated mode single photon detector at telecom wavelengths. The charge number of an avalanche pulse rather than the peak current is monitored for single-photon detection. The transient spikes in conventional gated mode operation are canceled completely by integrating, which enables one to improve the performance of single photon detector greatly with the same avalanche photodiode. This method has achieved a detection efficiency of 29.9% at the dark count probability per gate equal to 5.57E-6/gate (1.11E-6/ns) at 1550nm.

description: Massive low surface brightness galaxies have disk central surface brightnesses at least one magnitude fainter than the night sky, but total magnitudes and masses that show they are among the largest galaxies known. Like all low surface brightness (LSB) galaxies, massive LSB galaxies are often in the midst of star formation yet their stellar light has remained diffuse, raising the question of how star formation is proceeding within these galaxies. We have undertaken a multi-wavelength study to clarify the structural parameters and stellar and gas content of these enigmatic systems. The results of these studies, which include HI, CO, optical, near UV, and far UV images of the galaxies will provide the most in depth study done to date of how, when, and where star formation proceeds within this unique subset of the galaxy population.

Philoplitis adustipalpus

description: Philoplitis adustipalpus Ahmad, 2005: 1736. Holotype: ♀, INDIA (Zoology Department, Aligarh Muslim University). Not examined. Diagnosis. This species is the only known one with palpi completely brown, and it also has the shortest metatibial spurs, the inner one being 0.45× the length of the basitarsus (> 0.50 in all other species). It is separated from P. coniferens by the combination of black color and shorter length/width ratio of mediotergite 1; from P. striatus by its smooth mediotergite 2, much shorter tergum 3 and shorter inner metatibial spur (compared to length of both basitarsus and outer spur); from P. masneri by the color of mediotergite 2 and its length/apical width ratio; and from P. punctatus by the length of inner metatibial spur and shape of mediotergite 2. Comments. This is the only species for which we were not able to study specimens. It was described from two females collected in northern India (Uttar Pradesh). Based on the description and three figures provided by the authors (Ahmad et al., 2005) it is clearly separated from the closer species geographically (P. striatus, from southern India) as well from as the rest of the species within the genus.

description: We construct an exactly soluble spin-$\frac{1}2$ model on a honeycomb lattice, which is a generalization of Kitaev model. The topological phases of the system are analyzed by study of the ground state sector of this model, the vortex-free states. Basically, there are two phases, A phase and B phase. The behaviors of both A and B phases may be studied by mapping the ground state sector into a general p-wave paired states of spinless fermions with tunable pairing parameters on a square lattice. In this p-wave paired state theory, the A phase is shown to be the strong paired phase, an insulating phase. The B phase may be either gapped or gapless determined by the generalized inversion symmetry is broken or not. The gapped B is the weak pairing phase described by either the Moore-Read Pfaffian state of the spinless fermions or anti-Pfaffian state of holes depending on the sign of the next nearest neighbor hopping amplitude. A phase transition between Pfaffian and anti-Pfaffian states are found in the gapped B phase. Furthermore, we show that there is a hidden SU(2) gauge symmetry in our model. In the gapped B phase, the ground state has a non-trivial topological number, the spectral first Chern number or the chiral central charge, which reflects the chiral anomaly of the edge state. We proved that the topological number is identified to the reduced eta-invariant and this anomaly may be cancelled by a bulk Wess-Zumino term of SO(3) group through an index theorem in 2+1 dimensions.

description: The coronavirus disease 2019 (COVID-19) is an infectious disease that mainly affects the host respiratory system with ~80% asymptomatic or mild cases and ~5% severe cases. Recent genome-wide association studies (GWAS) have identified several genetic loci associated with severe COVID-19 symptoms, such as 3p21.31 locus (SLC6A20, LZTFL1, CCR9, FYCO1, CXCR6, and XCR1). We implemented integrative approaches, including transcriptome-wide association studies (TWAS), colocalization, and functional element prediction analyses, to interpret the genetic risks in lung, whole blood, and immune cells using two independent GWAS datasets from Host Genetics Initiative round 4 A2 and Severe COVID-19 GWAS Group. To understand the context-specific molecular alteration, we further performed deep learning-based single cell transcriptomic analyses on a bronchoalveolar lavage fluid (BALF) dataset from moderate and severe COVID-19 patients. In TWAS, colocalization, and functional analysis, we discovered CXCR6 has a protective effect on lung and a risk effect on whole blood, respectively. In lung resident memory CD8+ T (TRM) cells, we found a 2.24-fold decrease of cell proportion and lower expression of CXCR6 (fold change = 0.56, two-sided Wilcoxon p = 1.8 × 10-18) in severe patients than moderate patients. Pro-inflammatory transcriptional programs, apoptosis, and hypoxia pathways were highlighted in TRM cells transition from moderate to severe groups. We illustrated one potential mechanism of host genetic variants or other unknown risks that might impact the severity of COVID-19 through altering the expression of CXCR6 and lung TRM cell proportion and stability, therefore, impairing the first-line defense in lung.
Critical state analysis of orthogonal flux interactions in pinned superconductors

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: We show that, based on the critical state model for flux-line pinning in hard superconductors, one can assess the magnetic moment relaxation induced by the oscillations of a perpendicular magnetic field. Our theory follows a recent proposal of using phenomenological 2D modeling for the description of crossed field dynamics in high-T$_c$ superconductors [{\tt arXiv:cond-mat/0703330}]. Stationary regimes with either saturation to metastable configurations, or complete decay to the thermodynamic equilibrium are obtained. The transition between both types of response is related to the disappearance of a flux free core within the sample. As a common feature, a step-like dependence in the time relaxation is predicted for both cases. The theory may be applied to long bars of arbitrary and non homogeneous cross section, under in-plane magnetic field processes.

Mourning the loss of self : a universal change process and class of therapeutic event
Creators: name: Brooks, Dale Theodore
Publisher: name: University of British Columbia
Year: 2010

description: This study asserts that loss has been primarily focused on in terms of a set of reactions whose goals and content tend to be externally orientated. The thesis presented here states that the consideration of reaction to loss is incomplete without a detailed understanding of how the phenomenological self, on the intrapsychic level, is effected by loss. Consequently, this study takes a comprehensive look at how loss can effect this level of the phenomenological self, as well as the types of losses it can experience. An attempt is made to demonstrate that these losses to the phenomenological self can be identified and defined as a generic set of experiences, or, class of psychological events, which when taken together, this study considers as the loss of self. Given this class of psychological events, it is further claimed that mourning the loss of self, in different forms, is a universal change process. When dealt with in therapy this change process of mourning the loss of self is considered as a class of therapeutic event. An extensive literature review examines the basis for these claims, and provides the foundations for the presentation of a clinical model for mourning the loss of self. In this model, self, types of loss of self, and the process of mourning the loss of self, as relevant to this study, are defined. Utilization of this model for therapeutic purposes is demonstrated in case studies, and implications for research, as well as areas of application, are suggested.

description: A critical discussion of the present signals for the phase transition to quark-gluon plasma (QGP) is given. Since hadronic rescattering models predict much larger flow than observed from 1 to 50 A GeV laboratory bombarding energies, this observation is interpreted as potential evidence for a first-order phase transition at high baryon density. A detailed discussion of the collective flow as a barometer for the equation of state (EoS) of hot dense matter at RHIC follows. Here, hadronic rescattering models can explain < 30 % of the observed elliptic flow v_2 for $p_T > 2$ GeV/c. This is interpreted as an evidence for the production of superdense matter at RHIC. The connection of v_2 to jet suppression is examined. A study of Mach shocks generated by fast partonic jets propagating through the QGP is given. The main goal is to take into account different types of collective motion during the formation and evolution of this matter. A significant deformation of Mach shocks in central Au+Au collisions at RHIC and LHC energies as compared to the case of jet propagation in a static medium is predicted. A new hydrodynamical study of jet energy loss is presented.

description: The triple nucleus of M31 consists of a population of old red stars in an eccentric disk (P1 and P2) and another population of younger A stars in a circular disk (P3) around M31's central supermassive black hole (SMBH). We argue that P1 and P2 determine the maximal radial extent of the younger A star population and provide the gas that fueled the starburst that generated P3. The eccentric stellar disk creates an $m=1$ non-axisymmetric perturbation to the potential. This perturbed potential drives gas into the inner parsec around the SMBH, if the pattern speed of the eccentric stellar disk is $Ω_p \lesssim 3-10 {\rm km s^{-1} pc^{-1}}$. We show that stellar mass loss from P1 and P2 is sufficient to create a gravitationally unstable gaseous disk of $\sim 10^5\Msun$ every $0.1-1$ Gyrs, consistent with the 200 Myr age of P3. Similar processes may act in other systems to produce very compact nuclear starbursts.

description: We present the results of three-dimensional simulations of the deep convective envelope of a young (10 Myr) one-solar-mass star, obtained with the Anelastic Spherical Harmonic code. Since young stars are known to be faster rotators than their main sequence counterparts, we have systematically studied the impact of the stellar rotation speed, by considering stars spinning up to five times as fast as the Sun. The aim of these nonlinear models is to understand the complex interactions between convection and rotation. We discuss the influence of the turbulence level and of the rotation rate on the intensity and the topology of the mean flows. For all of the computed models, we find a solar-type superficial differential rotation, with an equatorial acceleration, and meridional circulation that exhibits a multicellular structure. Even if the differential rotation contrast decreases only marginally for high rotation rates, the meridional circulation intensity clearly weakens according to our simulations. We have also shown that, for Taylor numbers above a certain threshold (Ta>10^9), the convection can develop a vacillating behavior. Since simulations with high turbulence levels and rotation rates exhibit strongly cylindrical internal rotation profiles, we have considered the influence of baroclinic effects at the base of the convective envelope of these young Suns, to see whether such effect can modify the otherwise near cylindrical profiles to produce more conical, solar-like profiles.

description: This study investigated changes in oxidative stress and the relevant mechanisms in the liver of goats fed a high-concentrate (HC) diet for 5 weeks. Twelve goats were randomly assigned to a low-concentrate (concentrate-to-forage = 55:45, LC, n = 6) or HC diet (concentrate-to-forage = 90:10, n = 6), with dry matter as the base. Enzyme activity assays, real-time polymerase chain reaction and western blotting were used to evaluate antioxidant parameters and gene expression in the liver. Superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), total nitric oxide synthase activity and total antioxidant capacity (T-AOC) in the liver declined (p < .01) in HC-fed goats compared to those in LC-fed goats. The mRNA levels of GPX1, CAT and SOD1 were down-regulated (3.69, 47.37 and 27.61%, respectively) in HC-fed goats compared to those in LC-fed goats. Furthermore, glutathione S-transferase M1 (GSTM1) was upregulated (466.35%, p < .01) in the liver of HC-fed goats. The mRNA and protein levels of the nuclear factor E2-related factor 2 (NRF2) and total glucocorticoid receptor (GR) declined (p < .05) in HC-fed goats (by 28.57, 33.1, 30.85 and 34%, respectively). However, the nuclear translocation of GR increased (p < .05; by 44.75%) in HC-fed goats. Negative correlations were detected for hepatic nuclear GR protein expression with hepatic CAT activity and GPx activity. In conclusion, feeding an HC diet to goats for 5 weeks suppressed NRF2-dependent antioxidant responses and enhanced GR nuclear translocation in the liver.HighlightsFeeding goats high-concentrate diets suppresses NRF2-dependent antioxidant responses in liver, downregulating NRF2 and altering SOD1, GPx and CAT activity.This suppression of NRF2-dependent antioxidant responses is associated with GR activation in the liver of goats. Feeding goats high-concentrate diets suppresses NRF2-dependent antioxidant responses in liver, downregulating NRF2 and altering SOD1, GPx and CAT activity. This suppression of NRF2-dependent antioxidant responses is associated with GR activation in the liver of goats.

description: This study focused on the experience of involuntary job loss for managers and professionals. Fifteen males and females provided details of their experience through in-depth interviews. The critical incident technique was used as the approach to identify the high points and low points during their term of unemployment. The most frequently reported positive incidents included interviews, positive feedback from others, support of friends, family and counselling, and lack of financial pressures. The negative incidents most frequently reported included leaving the previous employer, rejection, lost role, interviews and lost career opportunities. In addition, the research participants reported shock and relief as the two most frequent responses to the termination. When asked about whether a change in attitude to work had occurred 11 reported some change following termination. The most prominent result of this research points to the experience of unemployment as largely an individual experience, only four categories of critical incidents included incidents reported by more than 50% of the participants interviewed. Counsellors may benefit from this research which provides information particular to this group and which will assist them in determining appropriate counselling techniques and interventions.

description: We study the long term evolution of magnetic fields generated by a collisionless relativistic $e^+e^-$ shock which is initially unmagnetized. Our 2D particle-in-cell numerical simulations show that downstream of such a Weibel-mediated shock, particle distributions are close to isotropic, relativistic Maxwellians, and the magnetic turbulence is highly intermittent spatially, with the non-propagating magnetic fields forming relatively isolated regions with transverse dimension $\sim 10-20$ skin depths. These structures decay in amplitude, with little sign of downstream merging. The fields start with magnetic energy density $\sim (0.1-0.2)$ of the upstream kinetic energy within the shock transition, but rapid downstream decay drives the fields to much smaller values, below $10^{-3}$ of equipartition after $10^3$ skin depths. In an attempt to construct a theory that follows field decay to these smaller values, we explore the hypothesis that the observed damping is a variant of Landau damping in an unmagnetized plasma. The model is based on the small value of the downstream magnetic energy density, which suggests that particle orbits are only weakly perturbed from straight line motion, if the turbulence is homogeneous. Using linear kinetic theory applied to electromagnetic fields in an isotropic, relativistic Maxwellian plasma, we find a simple analytic form for the damping rates, $γ_k$, in two and three dimensions for small amplitude, subluminous electromagnetic fields. We find that magnetic energy does damp due to phase mixing of current carrying particles as $(ω_p t)^{-q}$ with $q \sim 1$. (abridged)

description: Tradução de leaflet do Projeto AGFORWARD - As oliveiras, para terem um rendimento elevado, necessitam de muita luz e compassos largos. Assim, tanto os olivais tradicionais como os densidade elevada apenas intercetam 50 a 55% da luz solar. A restante chega ao solo e estimula o crescimento de infestantes. Porque não plantar, então, outra cultura comercializável debaixo das árvores, para aproveitar essa luz? A cultura sob o coberto terá de ser tolerante à sombra. Uma boa possibilidade é o espargo silvestre (Asparagus acutifolius), que é uma iguaria culinária no Mediterrâneo. Os turiões dos espargos podem ser colhidos e vendidos nos mercados locais. Ao desenvolverem-se sob as árvores, os espargos não influenciam o rendimento do olival e produzem uma cultura adicional.

Non-Relativistic Strings in Expanding Spacetime

description: We obtain a non-relativistic diffeomorphism invariant string action as a special limit of the Nambu-Goto action in an FLRW background. We use this action to study non-relativistic string dynamics in an expanding universe and construct an analytic model describing the macroscopic properties of non-relativistic string networks. The non-relativistic constraint equations allow arbitrarily small string velocities and thus a `frustrated' equation of state for non-interacting strings can be obtained without the need of a velocity damping mechanism. Assuming that colliding string segments reconnect by exchange of partners, non-relativistic string networks exhibit scaling behaviour, but with enhanced energy densities due to the reduced average string velocity. Non-relativistic string networks can be relevant in several contexts in condensed matter physics and cosmology.

description: Dans un contexte marqué par des changements technologiques, le développement des employés joue un rôle crucial pour intégrer ces innovations technologiques. C’est pourquoi des sommes considérables sont investies, chaque année, dans la formation par les entreprises. Étant donné les montants investis, il est évident que les décideurs souhaitent connaître l’impact qu’ont ces formations sur leurs entreprises ou leurs organisations. Ainsi l’évaluation de la qualité et de l’efficacité de la formation occupe une place importante. La formation Évaluation clinique – Infirmière (ECI) (2019) a été mise en place par le centre des formations (CeFor) du CHUV, suite à une demande émise par la Direction des soins (hiérarchie supérieure). Après que la filière d’évaluation du CeFor du CHUV a développé un dispositif d’évaluation (niveau 3 de Kirkpatrick) en s’inspirant du modèle Cycle de Construction et de Gestion Qualité d’Évaluation du Transfert (CGQET), nous allons dans ce mémoire étudier l’étape 7 « Feedback ». Plus particulièrement, après un recensement de la littérature sur le feedback, nous avons mis en place un feedback destiné aux intervenants pédagogiques de cette formation ECI qui sont les formateurs et coachs cliniques. La présente recherche a pour but d’étudier si les informations et les modalités de présentations produisent dans les faits les différents effets escomptés que nous avons relevés dans la littérature.

description: To beat PNS attack, decoy state quantum key distribution (QKD) based on coherent state has been studied widely. We present a decoy state QKD protocol with modified coherent state (MCS). By destruction quantum interference, MCS with fewer multi-photon events can be get, which may improve key bit rate and security distance of QKD. Through numerical simulation, we show about 2-dB increment on security distance for BB84 protocol.

description: Les études portant sur la thématique du sens au travail ne manquent pas ces dernières années. La crise de la modernité, pour reprendre l’expression de Dubet (2002), n’épargne en effet que bien peu de domaines professionnels. Cependant, dans bon nombre d’études consultées sur le sujet, les caractéristiques d’un « travail qui a du sens » semblent souvent acceptées comme faisant «sens en soi», indépendamment des dispositions propres du travailleur. Cette constatation semble d’ailleurs être partagée par Bernaud (2018) qui, dans sa synthèse sur les travaux de psychologie portant sur le sens à l’école, au travail et à la retraite, déplore le fait que « beaucoup de productions scientifiques s’appuient sur des échelles qui mesurent un aspect du sens, donnant une coloration superficielle au problème. » (p.105). Prenant acte de la réflexion de Bernaud, le présent travail de recherche s’attèle dès lors à décrypter les processus subjectifs d’élaboration et de détermination du sens du travail en milieu scolaire en adoptant une approche d’ordre phénoménologique qui, selon Meyor (2005) invite à dépasser le monde perçu comme un « en-soi » et à opérer une conversion du regard permettant « de mettre en lumière les actes de conscience par lesquels nous constituons le monde en termes de sens ». Par « processus », il est donc entendu que le travail ne détiendrait pas de sens en soi, mais que le sens du travail relèverait plutôt d’un processus interne au sujet. Afin de marquer cet écart avec les concepts de « sens » ou de « signification », le concept de « sensification » a donc été développé pour les besoins de cette étude et définit comme suit : processus subjectif et dynamique par lequel un individu investit son action d’une signification qui lui est propre. Finalement, en s’intéressant au sens du travail dans un milieu professionnel fortement institutionnalisé, la présente recherche ne peut faire l’économie de la relation acteur-institution. A cet égard, une attention particulière a également été portée aux dispositions individuelles et institutionnelles en postulant que l’alignement de celles-ci seraient un facteur déterminant de la sensification du travail.

description: L’objet de la recherche présentée dans ce mémoire de fin d’études porte sur la relation entre pédagogie, créativité et émotions d’accomplissement, relation évaluée dans le cadre d’un dispositif expérimental déployé au cours de deux séquences de français dans une classe hétérogène et pluriculturelle de 21 élèves de 4H au sein d’un établissement du Canton du Valais. Précisément, l’évaluation visait à répondre à la question de recherche suivante : comment est-ce que le dispositif créatif en français influence les émotions d’accomplissement des élèves de 4H ? Les deux séquences du dispositif expérimental, prenant toutes deux pour support la lecture d’une histoire (Lulu Vroumette), ont consisté, pour la première, en un cours à la pédagogie « traditionnelle » ou « standard » et, pour la seconde, en un cours à la pédagogie « créative » : au moyen d’un questionnaire sur les émotions d’accomplissement inspiré de Pekrun, les élèves ont été invités, à l’issue des deux séquences, à exprimer les émotions qu’ils avaient ressenties durant ces dernières. Les résultats ont été traités quantitativement et ont permis de mettre en lumière des tendances significatives : il a en effet été constaté qu’un dispositif de type créatif, aussi modeste soit-il comme celui déployé ici, est favorable au développement d’émotions d’accomplissement positives en lien avec l’apprentissage du français dans cette classe de 4H valaisanne, du fait de la prévalence plus importante des émotions d’accomplissement positives en condition créative qu’en condition standard ainsi que, simultanément, une prévalence moins importante des émotions d’accomplissement négatives en condition créative qu’en condition standard. Le dispositif créatif a également sollicité une implication plus interactive de la personne enseignante, celle-ci générant par conséquent davantage de stimulations dans le groupe classe par rapport à la condition standard.
