[more ▼] La littérature dite « panoramique », selon l’expression rétrospective de Walter Benjamin (Paris, capitale du XIXe siècle), forme un ensemble complexe de textes et d’illustrations participant à un phénomène de société particulièrement notable en France sous la monarchie de Juillet. Prolongeant l’esthétique du tableau textuel, à laquelle se mêlent les influences de la petite presse et des sciences humaines en émergence, les recueils d’études de mœurs se multiplient à cette époque sous des formes diverses (galeries, magasins, musées) et mettent à l’honneur des types et des comportements sociaux. Dans ce contexte, avant l’ambitieux projet haussmannien, le corpus panoramique manifeste un intérêt particulier pour la figuration en mots et en images de la métropole parisienne. En témoignent les nombreuses Physiologies des années 1840 qui offrent des parcours dynamiques dans l’environnement urbain et multiplient les vues de lieux de loisirs et de promenades tels que les bals, les cafés, les passages, les parcs et les cabinets de lecture. Parmi les plus représentatives à cet égard, notons les Physiologies des Champs-Élysées, des Quartiers de Paris, des Rues de Paris, des Diligences et des Grandes Routes, de l’Omnibus, des Cafés de Paris, du Jardin des Plantes et du Flâneur. Ni véritables documents historiques, puisqu’elles mêlent la réalité à la fiction, ni tout à fait œuvres littéraires malgré plusieurs contributions balzaciennes significatives, ces monographies illustrées présentent un traitement particulier de la référence géographique. On examinera la spécificité de ces modes de représentation en rapport avec la nature des savoirs produits sur la ville : le type n’est-il qu’un ensemble de stéréotypes ? quelle distance critique adopter face aux informations urbaines dont regorgent ces textes ? quelles médiations mettent-ils en œuvre dans leur prise en charge des données empiriques ? Ces questions permettront de proposer des éléments de méthodologie pour aborder un traitement textuel et iconographique de l’espace urbain qui, à l’examen, apparaît moins tributaire de l’invention technique et picturale du panorama que d’un réinvestissement particulier de l’ethnographie et de la zoologie en plein développement.

[more ▼] Short C fibers-Mg matrix composites have been produced by friction stir processing sandwiches made of a layer of C fabric stacked between two sheets of either the ductile Mg alloy AZ31B, or of the less ductile alloy AZ91D, that is capable of age hardening. It has been shown that the choice of the optimal experimental parameters for the production of sound composites was strongly dependent on the nature of the matrix. 3D X-ray tomography reveals that the fibers orient along the onion rings and that they are more or less fragmented depending on the local shear stress during the process. The fiber volume fraction is increased when the nugget volume decreases in particular for the AZ91D base material and for a high advancing speed for the AZ31B base material. The fiber volume fraction influences directly the grain size, the hardness and the tensile properties of the composites.

[more ▼] This article aims to examine and highlight what appears to have been the typical approach whereby Saussure built his arguments. We focus on the genesis of a theme addressed by the linguist in the preparation of a report on a book published by J. Schmidt (1895), namely the many anomalies of the (generally assumed) “theory of sonorants”. Seeking the multiple reformulations of this idea throughout this dossier (relatively complete, which is rare in Saussure), we try to highlight some characteristics specifi c to the theoretical arguments in the humanities.

[more ▼] The annual springtime minimum in stratospheric ozone over the Antarctic is primarily caused by catalytic reactions of ozone and chlorine. The Montreal Protocol on Substances that Deplete the Ozone Layer (with its subsequent amendments) restricts the emissions of ozone depleting substances. HCFC-22 has been the primary replacement for both CFC-11 and CFC-12, which has led to an increase in its atmospheric abundance. The Atmospheric Chemistry Experiment (ACE) is a mission on-board the Canadian satellite SCISAT. The primary instrument on SCISAT is a highresolution infrared Fourier Transform Spectrometer (ACE-FTS). With its wide spectral range, the ACE-FTS is capable of measuring an extensive range of gases including key CFC and HCFC species. The altitude distribution from the ACE-FTS profiles provides information that is complementary to the ground-based measurements that have been used to monitor these species. The ACE-FTS measurements compare well with surface in situ and balloon measurements. A preliminary validation of HCFC-22 using ground-based FTSs is discussed. The zonal mean distribution of HCFC-22 as observed by ACE-FTS is presented. The global distributions of HCFC-22 have been compared to the Global Modelling Initiative (GMI) Combined Stratospheric-Tropospheric Model, a chemistry and transport model. Large differences between the model and ACE-FTS measurements of HCFC-22 reveal issues with the boundary value mixing ratios. The comparison of stratospheric measurements with GMI suggest that there may be a missing loss process in the stratosphere, some issues with transport circulation and polar cap averaging in the current run, or a combination of the two processes. We propose the reaction of HCFC-22 with atomic chlorine as a potentially important loss process in the lowermost stratosphere and the lower stratosphere.

[more ▼] La Lozana andaluza describes the story of a gifted prostitute which adventures occur in Rome before the Sack of 1527. However, the writer, an Andalusian priest, fills his text with biblical references. As the purpose of his Portrait gives rise to debate and is valued according to its (un)appropriateness to the Christian doctrine, we study the role of the biblical intertextuality in the determination of this purpose. Indeed, in La Lozana, the biblical hypotext presents its traditional function as an auctoritas but it also constitutes a favored tool of linguistic games, a source of comic effects, and supplies the framework of the Portrait. In this work we examine the mixed intertextuality used by an autor which anticlericalism was sometimes interpreted as an erasmist feature. Consequently, we highlight, always making links with the biblical marks of La Lozana, first some evidences that make an orthodox interpretation possible, and later some dissident tendencies that cross the story. The biblical intertextuality produces a duplicity of the discourse that prevents an univocal interpretation. In fact, this posture is understandable during a time which is disturbed by religious tensions.

[more ▼] In this talk, we discuss an extension of the strong axiom of revealed preferences to collective households. The question that we address is whether a set of observed consumption baskets can be decomposed in such a way that each of the derived data sets reflects the choices of a “rational” (i.e., utility-maximizing) individual member of the household. Although testing revealed preference axioms on data generated by a single decisionmaker can be done in polynomial time, the extension to two-member households is NP-complete. We propose two algorithms for testing the collective consumption model on large data sets. The first one is an exact algorithm based on a new mixed-integer programming formulation, whereas the second one is a heuristic based on a simulated annealing procedure that solves a global optimization formulation of the problem. Computational experiments are performed on real-life data.
