Le croisement du football avec la publicité semble structurer l’espace stade en plusieurs dimensions. Deux critères sont ainsi repérés : une structuration verticale et une structuration horizontale. La structuration verticale s’opère par exemple dans les stades construits sur plusieurs niveaux. On observe que l’installation des panneaux publicitaires y suit un ordre de grandeur croissant partant de bas vers le haut, divisant le stade en plusieurs espace-unités à valeur inégales (le rez-de-chaussée, le premier niveau, le deuxième niveau, etc.). La structuration horizontale est réalisée à partir, par exemple, des effets de distance que créent la situation du spectateur et la zone d’exposition du panneau publicitaire : le spectateur situé à un certain endroit (le rez-de-chaussée, par exemple) est parfois invité à exécuter certains mouvements (le plus souvent latéraux : regards à l’angle du profil en suivant le déplacement du ballon). Ce faisant, il découvre des panneaux publicitaires par un rythme hiérarchique et discriminatoire : certains panneaux sont bien découverts ; d’autres, il ne les découvre que très peu ; d’autres encore ils ne les découvrent pas du tout. (Un spectateur situé au rez-de-chaussée à la hauteur de la ligne médiane du terrain du côté de la tribune de presse et qui regarde le match, peut découvrir des panneaux publicitaires situés en face de lui lorsqu’il suit, par exemple, des séquences de passe qui se déroulent le long de la ligne de touche opposée: regard de face ; il découvre des panneaux placés derrières les buts lorsqu’il regarde un but qui s’exécute : regard de profil ; il ne voit pas du tout les panneaux situés en contrebas de son siège, par exemple les panneaux derrières les bancs des staffs techniques des équipes). Les espaces-unités construits par ces deux types de structuration deviennent en réalité des lieux d’attribution des compétences modales des sujets (pouvoir faire, devoir faire, vouloir faire, savoir faire), les spectateurs en l’occurrence, qui sont les cibles de la communication publicitaire. Cette attribution se réalise en fonction de quatre régimes de distribution modale des panneaux : régime d’exposition, régime d’accessibilité, régime d’inaccessibilité et régime d’obstruction. Il s’instaure ainsi tout un système de hiérarchisation du public qui vient assister à un match de football au stade, lequel se réalise notamment en fonction de leurs différents degrés d’exposition aux messages publicitaires et qui, par ailleurs, sont parfois rendus possible par la dimension narrative du jeu (l’exécution des séquences : but, passe, remise en jeu, remise de touche, etc.). Plusieurs cas de ce système de hiérarchisation adviennent au cours d’un match. Par exemple, lorsque la diffusion des messages publicitaires tient compte du type de public sollicité pour le découvrir. C’est le cas de la discrimination des messages qu’opèrent les annonceurs lorsqu’ils peuvent choisir d’orienter certains messages vers un public spécifique, celui installé dans la tribune d’honneur par exemple, à l’exclusion d’autres. Notre étude explore cette structuration de l’espace qu’opère au stade le croisement du football et la publicité, en recourant aux outils de sémiotique. Nous considérons entre autres le football et la publicité comme deux discours présentant des schémas énonciatifs et argumentatifs différents : celui fondé sur une logique de l’épreuve engagée entre deux équipes en situation ludique, pour le football, et celui basé sur une logique communicationnelle fondé sur un schéma argumentatif de type persuasif, pour la publicité.

"Rare diseases" affect less than one person in 2000 in the European Union. In addition to this low prevalence rate, they are defined as being generally the object of insufficient knowledge and recognition, which often leads patients and their relatives to situations of diagnostic and therapeutic wandering. Then, many gather in some "rare diseases organizations" that aim at guiding concerned people in their health- and disease-related itineraries and at improving their quality of life. Drawing on a multi-sited ethnography conducted in Belgium, this communication presented some insights of the categorization work (Bowker & Star, 2000) operated by the "Rare Disease Organization" in Belgium in order to construct, consolidate, and expand a univocal category of "rare diseases". It particularly highlighted the mobilization of patients and relatives' narratives of lived experiences and common problematics as collective resources to categorize "rare diseases". Doing this, the organization tends to encompass the multiplicity and the variety of corresponding diseases, situations, experiences, and conceptions of patients and their relatives, in the aim of forming "a single front" and speaking from "a single voice" to publicized and make their claims heard. Moreover, the communication interrogated the articulation between the singularity of patients and relatives' narratives and the collective logic that they reflect (Douglas, 1986). How are rare diseases-related experiences exchanged within patients and relatives' organizations? How do they align with each other to transform them into collective resources to categorize "rare diseases"? What are the elements that make sense and what, conversely, is lost in this passage from the singularity to the collective? Moreover, what are the relationships between the narratives of patients and relatives and the wider social, political and medical contexts in which they are embedded? As a precision, this ongoing doctoral research fits into Science and Technology Studies, Anthropology of health and disease, and Sociology of knowledge. [less ▲]

Age discrimination at work can potentially affect every worker. Indeed, like ‘old’ workers, young ones hired in their first job elicit the idea that they have quite interesting social abilities but lack of competence, which constitutes a case of paternalistic stereotypes (Fiske, Cuddy, Glick, & Xu, 2002). Generally, the negative (incompetence) facet of such stereotypes is not blatantly expressed, but is subtly conveyed behind an apparently positive discourse. Consequently, it is considered as being generally under-detected, while harmful. In this paper, we examine whether paternalistic stereotyping’s under-detection is real or if it is due to the use of inadequate measures. Based on a study showing that targets feel that something is wrong (Dardenne, Dumont, & Bollier 2007), we rely on affective measures to investigate whether the detection of the subtly conveyed negative facet of paternalistic stereotypes calls for subtle, implicit measures. In Study 1, explicit self-reports of targets’ affective states after a meeting with a paternalistic boss revealed mainly positive affect. In Study 2, an implicit emotional measure however revealed the presence of a negative affective state. The last Study, using a more ecological affective measure, demonstrates that paternalistic stereotypes trigger an ambivalent affective reaction. Altogether, the three studies suggest that the negative facet of paternalistic stereotypes is not as under-detected as we thought. [less ▲]

Background: Leishmaniasis is a protozoan disease caused by parasites of the genus Leishmania, transmitted to humans by sandflies. The diagnosis of leishmaniasis is often challenging as it mimics many other infectious or alignant diseases. The disease can present in three ways: cutaneous, mucocutaneous, or visceral leishmaniasis, which rarely occur together or consecutively. Case presentation: The patient was a 52 years old immunosuppressed Belgian woman with a long history of severe rheumatoid arthritis. She underwent bone marrow biopsy to explore thrombocytopenia. Diagnosis of visceral leishmaniasis was made by identification of Leishman Donovan (LD) bodies in macrophages. Treatment with liposomal amphotericin B was successful. She later developed cutaneous leishmaniasis treated with amphotericin B lipid complex. She next presented with relapsing cutaneous lesions followed by rapidly progressing lymphadenopathies. Biopsy confirmed the diagnosis of leishmaniasis. Treatments by miltefosine, amphotericin B, N-methyl-glucamine antimoniate were subsequently initiated. She later presented a recurrent bone marrow involvement treated with intramuscular paromomycin and miltefosine. She died two years later from leukemia. At the time of death, she presented with a mucosal destruction of the nose. A Leishmania-specific PCR (Polymerase Chain Reaction) identified L. infantum as etiological agent. Conclusions: Clinicians should be aware of the potential concomitant or sequential involvement of multiple anatomic localizations of Leishmania in immunosuppressed patients. [less ▲]

In Mohsin Hamid’s The Reluctant Fundamentalist, Changez, a Pakistani returnee from the US in a post 9/11 context, notes that “the confession that implicates its audience is […] a devilishingly difficult ball to play. Reject it and you slight the confessor; accept it and you admit your own guilt.” Although Changez’s remark foregrounds his past uneasiness at the confessional tone regularly used by his Anglo-American boss, it also extends to the reader, who now occupies the “devilishingly difficult” position of the one who is being force-fed Changez’s confession – namely his “failed love-story” (Hamid) with the US. Both a confession of growing hatred towards the US and a dramatic monologue addressed to an unnamed American ‘you’, Hamid’s novel is highly influenced by the ‘I/you’ confessional dialectics wielded by Albert Camus in La Chute – a dialectics which is also taken up by Kamel Daoud in Meursault, contre-enquête, a rewriting of Camus’ L’Etranger that grants Meursaut’s victim a name and a story in today’s Algeria. Through a discussion of the intertextual genealogies between Hamid’s text and La Chute on the one hand, and between Daoud’s text, La Chute, and L’Etranger on the other, I wish to examine how Daoud’s and Hamid’s novels leave readers no choice but to negotiate conflicted identifications with the roles of ‘the confessor’ and ‘the listener’ in a context of growing Islamophobia, thus begging the question that Camus’ ‘existentialist’ texts have eluded, that is, to what extent empathy is framed by politics.

Notre travail porte sur l'étude du comportement des bétons auto-compactants ou auto-plaçants réalisés à base de sable recyclé et de sable recyclé broyé. La première étape consiste en une caractérisation physico-chimique et minéralogique (masse volumique, absorption d’eau, teneur en sulfates, composition chimique...) d’un sable de béton recyclé. Dans un deuxième temps, une étude des propriétés rhéologiques et mécaniques est réalisée sur des mortiers afin de réduire la quantité de matériaux naturels utilisés. La composition du mortier de base est dérivée d’une formulation type de béton auto-compactant préalablement vérifié sur la base de différents critères classiques (étalement au cône, t500, teneur en air,…). Notre étude s’intéresse d’une part aux impacts de la substitution du filler calcaire par du sable recyclé broyé (série 1) et d’autre part aux impacts de la substitution du sable naturel par du sable recyclé (série 2).

Comme J. Arnold et différents spécialistes l’attestent, le facteur émotionnel favorise l’environnement de l’apprentissage. L’on apprend plus vite, plus intensément et plus profondément. Alors, lorsqu’ un apprenant francophone – qui vit avec une conception du monde occidentale (notamment à la française) - rencontre une langue « lointaine », celle de l’autre civilisation, à savoir une langue qui réfléchit à la verticale, qui ne précise pas le sujet, qui est à la fois laconique et équivoque…bref, celle qui se trouve à l’opposé de l’horizon cartésien, quel genre d’alchimie se produirait ? Et quel est le rôle de l’enseignant dans tout cela ? Dans cet exposé, des réflexions issues de l’expérience de l’enseignement du japonais pour le public francophone de ces 5 dernières années seront passées en revue. La rencontre entre ces deux langues, très différentes, ne pourra point se faire sans provoquer de « choc » culturel. Et ce choc même, semble-t-il, constituerait l’élément décisif qui favorise l’environnement de l’apprentissage du japonais, la langue souvent qualifiée d’être très éloignée du français par son côté ambigu, obscur et qui cherche l’harmonie plutôt que la distinction. Parmi les différents facteurs qui influenceront l’impact émotionnel dans l’apprentissage du japonais par les Francophones, le choix adéquat de matières (corpora) sera particulièrement mis en avant. Quelques corpora propres à la langue japonaise (ex : onomatopées, façons de dire « non » à la japonaise, dictons) semblent être pertinents afin d’éveiller la curiosité de l’apprenant. Et ce déclic générerait l’intérêt chez ce dernier, ce qui l’incite à travailler consciencieusement cette nouvelle langue. Notre exposé aspire également à suggérer que cette prise de conscience linguistique – acquise grâce à l’apprentissage d’une langue étrangère – amènerait l’apprenant à réfléchir sur des caractéristiques de sa langue maternelle et de son fonctionnement, ancrés dans une culture et une société définies.

This paper aims at accounting for the uncertainties due to material structure and surface topology of microbeams in a stochastic multiscale model. For micro-resonators made of anisotropic polycrystalline materials, micro-scale uncertainties are due to the grain size, grain orientation, and to the surface profile. First, microscale realizations of stochastic volume elements (SVEs) are obtained based on experimental measurements. To account for the surface roughness, the SVEs are defined as a volume element having the same thickness as the MEMS, with a view to the use of a plate model at the structural scale. The uncertainties are then propagated up to an intermediate scale, the meso-scale, through a second-order homogenization procedure.From the meso-scale plate resultant material property realizations, a spatially correlated random field of the in plane, out of plane, and cross resultant material tensors can be characterized. Owing to this characterized random field, realizations of MEMS-scale problems can be defined on a plate finite element model. Samples of the macro-scale quantity of interest can then be computed by relying on a Monte-Carlo simulation procedure. As a case study, the resonance frequency of MEMS micro-beams is investigated for different uncertainty cases, such as grain preferred orientations and surface roughness effects. [less ▲]

The 2016 Belgium Report Card on Physical Activity for Children and Youth is the first systematic evaluation of physical activity (PA) behaviors, related health behaviors, health outcomes, and influences thereon, using the Active Healthy Kids Canada grading framework. A research working group consisting of PA experts from both Flanders and Wallonia collaborated to determine the indicators to be graded, data sources to be used, and factors to be taken into account during the grading process. Grades were finalized after consensus was reached among the research working group and 2 stakeholder groups consisting of academic and policy experts in the fields of PA, sedentary behavior, and dietary behavior. Eleven indicators were selected and assigned the following grades: Overall PA (F+), Organized Sport Participation (C-), Active Play (C+), Active Transportation (C-), Sedentary Behaviors (D-), School (B-), Government Strategies and Investment (C+), and Weight Status (D). Incomplete grades were assigned to Family and Peers, Community and the Built Environment, and Dietary Behaviors due to a lack of nationally representative data. In conclusion, despite moderately positive social and environmental influences, PA levels of Belgian children and youth are low while levels of sedentary behaviors are high. [less ▲]

Development of photochemistry in macroscopic batch reaction vessels is hampered due to inherent limitations: light penetration remains superficial, resulting in inhomogeneous irradiation and hence to side-reactions or product degradation due to overexposure. The recent implementation of photochemical processes in microreactors under continuous-flow conditions appeared to be much more powerful than its batch analogue in terms of irradiation efficiency and light penetration. Furthermore, the fine control of residence time ensures an accurate control of the irradiation time, avoiding side-reactions and degradation. The scalable photooxidation of (L)-methionine with singlet oxygen using Rose Bengal as a sensitizer was successfully implemented in a microreactor setup and led to total and selective conversion into methionine sulfoxide, an important building block for the organic synthesis of peptides or functionalized amino acid. The reaction was performed in less than 1 min while the same reaction in batch took 2 h. Other substrates as α-terpinene or citronellol were also photooxidized into high added value compounds using the same conditions. [less ▲]
