Sarah Mazouz, La République et ses autres. Politiques de l’altérité dans la France des années 2000

Résultat d’une enquête conduite dans le cadre d’une thèse de doctorat, l’ouvrage de Sarah Mazouz, chargée de recherche au CNRS, se donne comme une ethnographie de l’action publique et des pratiques administratives envisagées à travers le double prisme de la lutte contre les discriminations et de la politique de la naturalisation. L’articulation de ces deux objets s’ancre dans un effort visant à ressaisir les dynamiques de racialisation de « l’identité nationale » et conjointement l’économie s..

Left Ventricular Wall Motion Estimation by Active Polynomials for Acute Myocardial Infarction Detection

Echocardiogram (echo) is the earliest and the primary tool for identifying regional wall motion abnormalities (RWMA) in order to diagnose myocardial infarction (MI) or commonly known as heart attack. This paper proposes a novel approach, Active Polynomials , which can accurately and robustly estimate the global motion of the Left Ventricular (LV) wall from any echo in a robust and accurate way. The proposed algorithm quantifies the true wall motion occurring in LV wall segments so as to assist cardiologists diagnose early signs of an acute MI. It further enables medical experts to gain an enhanced visualization capability of echo images through color-coded segments along with their “maximum motion displacement” plots helping them to better assess wall motion and LV Ejection-Fraction (LVEF). The outputs of the method can further help echo-technicians to assess and improve the quality of the echocardiogram recording. A major contribution of this study is the first public echo database collection composed by physicians at the Hamad Medical Corporation Hospital in Qatar. The so-called HMC-QU database will serve as the benchmark for the forthcoming relevant studies. The results over HMC-QU dataset show that the proposed approach can achieve 87.94% accuracy, 92.86% sensitivity and 87.64% precision in MI detection even though the echo quality is quite poor and the temporal resolution is low.publishedVersionPeer reviewe

Identité éditoriale, identités sportives

Le Dossier analyse l’assignation d’identités catégorielles aux sportifs de haut niveau dans la presse. Les Échanges étudient l’intervention par l’image. Les Notes de recherche traitent la « relation diagnostique », la manière dont l’Université rend hommage à ses membres décédés, le rapport entre ludique et marchand d’un parc d’attraction pour enfants, l’expertise du jazz, le complotisme sur Facebook et la diversité des langues dans la musique populaire. En VO suit les représentations médiatiques de la violence genrée aux USA. Le Focus porte sur Les Sensibilités religieuses blessées de Jeanne Favret-Saada et 33 Newport Street de Richard Hoogart. Les Notes de lecture recensent 50 ouvrages. The media discourse on sport often focuses on elite athletes and assigns to them categorical identities (class, gender, race, origin, age…) for various emblematic purposes (for example, national heroes, representatives of a territory, of a culture…). The Issue analyzes these identification logics and their variations – according to editorial strategies and the readers communities built – in the specialized press and the sport sections of the generalist press, without forgetting to consider their reception by the athletes themselves. The Exchanges extend André Gunthert’s discussion on the intervention through the image. The Research Notes explore the “diagnostic relationship” for patients with West Syndrome and their families, how universities honor their deceased members, the relationship between play, commercial and educational practices in a children amusement park, the expertise of jazz in France, the conspiracy speeches on Facebook and the diversity of languages in French popular music. In Original Version, US researcher Lisa Cuklanz revisits three decades of work on representations of gendered violence in mainstream media. The Focus section provides an in-depth reading of a recent work by Jeanne Favret-Saada – Hurt Religious Feelings. Christianity, Blasphemy and Films, 1965-1988 – and on an older one by Richard Hoggart – A Local Habitation, 1918–40. The Book Reviews offer succinct overviews and analyses of more than 50 publications
