Monter un dossier en vue d’obtenir un label européen AOP ou IGP peut s’avérer fastidieux et long : cela implique un consensus entre producteurs, le cahier des charges comprend un volet technique mais aussi un volet socio-historique, et les étapes de la procédure s’étendent sur de nombreux mois. Les producteurs sont donc en droit de se demander quelles pourront être les retombées de cette labélisation. Cette présentation illustre les impacts socio-économiques des indications géographiques et démontre l’intérêt de ces labels pour les producteurs. [less ▲]

Le diagnostic médical d'une pathologie est un événement significatif dans les parcours de vie des patients et de leurs proches. Il vient catégoriser des symptômes, participer aux processus de (re)construction de soi, et induire des attitudes et comportements en vue d'intervenir activement sur les événements. Notamment, il correspond pour certains au moment de leur engagement au sein d'une association concernée par la pathologie ou le syndrome diagnostiqué en question. De telles associations de patients s'impliquent souvent dans diverses activités de production, de mobilisation et de circulation de connaissances sur les conditions et leurs causes. Ces modes d'activisme dits "basés sur la connaissance" (evidence-based activism) se caractérisent par une articulation étroite entre des connaissances issues d'expertise biomédicale et des connaissances expérientielles, issues des expériences vécues au quotidien par les patients et leurs proches, dont ils revendiquent la légitimité. S'inscrivant à la croisée des Science and Technology Studies et de l'anthropologie de la santé et de la maladie, la présente communication vise à explorer les dynamiques de cette articulation à partir d'une ethnographie multi-site menée auprès d'associations belges francophones concernées par des pathologies ou syndromes génétiques. Plus particulièrement, la communication s'intéresse à un projet d'information et de sensibilisation autour du trouble du spectre autistique (TSA) qui est développé par un groupe de parents concernés. Le TSA y est défini comme une condition complexe et multidimensionnelle, aux causes incertaines et controversées mais dont ils revendiquent la part déterminante de la génétique. Comment des "connaissances expérientielles" sont-elles produites, validées et mises en circulation dans le cadre de telles activités ? Au-delà de la simple information, les observations montrent qu'elles comportent des enjeux identitaires importants. [less ▲]

We explore three problems in this thesis and develop solution methods for each problem. First, an inventory routing problem for a perishable product with stochastic demands is considered and different approximate solution methods are developed to solve. Based on computational experiments, the solution methods are compared in terms of average profit, service level, and actual freshness. The impact of relevant parameters on the performance of the solution methods is investigated. Managerial insights are drawn by analyzing the impact of shelf life and store capacity on the profit. The value of considering uncertainty and the value of accessing full information are measured. The computational results highlight that a simple ordering policy can often replace a more sophisticated solution method, while preserving the same efficacy. Second, we introduce a vehicle routing problem (VRP) where a set of stores places deterministic orders to a logistics service provider (LSP) for two successive periods. Deliveries requested in each period can be shifted by the LSP to the other period, possibly with modified quantities. The LSP incurs a penalty for any diversion from the initial delivery period. The data regarding shifted delivery quantities and penalties are provided by the stores. From the perspective of the LSP, diversions could be beneficial if savings in the routing costs outweigh the penalties. In this work, we introduce a new two-period VRP model where the LSP seeks to improve its total cost, compared to solving two independent VRPs with fixed delivery periods, by allowing deliveries to be shifted. We solve this model to optimality by an efficient branch-and-price algorithm implementing several cutting-edge techniques. We draw algorithmic and managerial insights based on our test instances. Third, a two-period VRP is considered where the orders placed by stores for each period can be partially shifted to the other period, given that the sum of the delivery quantities in two periods to each customer is fixed. A linear penalization of delivery shifts is assumed based on the quantity shifted. We represent two mixed integer linear programming (MILP) formulations for the problem. A column-row generation algorithm to solve the LP-relaxation of the first formulation is developed. To solve the LP-relaxation of the second formulation, we develop a column generation algorithm. Details of two label-setting algorithms to solve the pricing problems of the column-row generation and column generation algorithms are discussed. Numerical results can be compared with a similar model in which only full delivery shifts are allowed. [less ▲]

The analysis of the of Silva’s collection of works places us in quite a disconcerting, yet no less encouraging, position, when re-assessing the different forms of importing literary movements. On one hand, the image attributed to Silva both by his contemporaries and his successors is that of the leading figure in the assimilation and absorption of the literary European movements that would give rise to modernism. On the other hand, the absence of public visibility for Silva’s works, be it through texts or paratexts, let us in a difficult situation to prove the poet’s will to position himself as the one who introduced the new literary movement to Colombia. If we accept from the outset, as we will in this article, that the Colombian poet possessed an obstinate determination to appropriate and assimilate the European literary movements that give rise to modernism, then we must entertain the possibility that Silva’s literary transfer took place through media other than books, journals or magazines. Our hypothesis is that by focusing on the acts of reading and poise, the literary coterie became the ideal platform for the Colombian writer to adopt and propagate the image of the decadent writer, which would become the embodiment of the aesthetic ideals of modern literature.

Combining the redox activity and remarkable adhesion propensity of polyphenols (such as catechol or pyrogallol) with the numerous tunable properties of poly(ionic liquid)s (PILs) is an attractive route to design inventive multifunctional macro-molecular platforms. In this contribution, we describe the first synthesis of a novel family of structurally well-defined PILs functionalized with catechol/pyrogallol/phenol pendants by organometallic-mediated radical polymerization (OMRP) using an alkyl−cobalt(III) complex as initiator and mediating agent. The living character of the chains is also exploited to produce di-and triblock PILs, and the facile counteranion exchange reactions afforded a library of PILs-bearing free phenol/catechol/pyrogallol moieties. Electrochemical investigations of catechol/pyrogallol-derived PILs in aqueous medium demonstrated the characteristic catechol to o-quinone transformations, whereas, quasi-reversible doping/undoping with supporting electrolyte cations (Li + /tetrabutylammonium +) has been observed in organic media, suggesting a bright future for this new family of redox-active PILs as cathode material for secondary energy storage devices. Also, pendant catechol/pyrogallol groups mediated sustained anchoring onto the gold surface conferred PILs properties to the interface. As a proof-of-concept, both the adsorption and inhibition of proteins on polymer modified surfaces have been demonstrated in real time using the quartz crystal microbalance with dissipation technique. The exquisite physicochemical tunability of these innovative surface-and redox-active PILs makes them excellent candidates for a broad range of potential applications, including " smart surfaces " and electrochemical energy storage devices.

An experimental determination of the mean vortex velocity in superconductors mostly relies on the measurement of flux-flow resistance with magnetic field, temperature, or driving current. In the present work we introduce a method combining conventional transport measurements and a frequency-tuned flashing pinning potential to obtain reliable estimates of the vortex velocity. The proposed device is characterized using the time-dependent Ginzburg-Landau formalism, where the velocimetry method exploits the resonances in mean vortex dissipation when temporal commensuration occurs between the vortex crossings and the flashing potential. We discuss the sensitivity of the proposed technique on applied current, temperature and heat diffusion, as well as the vortex core deformations during fast motion. [less ▲]

Dans les années 60, Grothendieck révolutionna la géométrie algébrique en introduisant le concept de topos. Faisant face à des situations où la notion d'ouvert était trop restrictive pour comprendre les phénomènes géométriques sous-jacents, il définit une nouvelle notion de topologie dans le langage de la théorie des catégories. Très utilisée pour résoudre des problèmes de géométrie et d'analyse contemporains, cette notion a aussi de nombreuses applications surprenantes en logique (théorie intuitionniste, équivalence de Morita, etc ...). Dans ce séminaire je proposerai une application de la théorie des topos de Grothendieck pour étudier les fonctions et les distributions tempérées. En effet, ces objets ne forment un faisceau que sur une topologie de Grothendieck particulière (la topologie sous-analytique), qui n'est pas une topologie au sens usuel du terme. Je montrerai alors, de manière abstraite, comment définir un faisceau de fonctions holomorphes tempérées qui a joué un rôle crucial dans la démonstration de la correspondance de Riemann-Hilbert (généralisation du 21ème problème d'Hilbert). En particulier, ce nouveau faisceau fournira une nouvelle définition, presque purement algébrique, des distributions de Schwartz. [less ▲]

Las siguientes consideraciones metodológicas surgen esencialmente de la confrontación de la teoría de las transferencias con mi corpus actual de trabajo, esto es, con las modalidades de importación literaria durante el modernismo, época que, como todos sabemos, constituyó un momento de apertura privilegiado para la apropiación y asimilación de las producciones culturales extranjeras. Los escollos metodológicos encontrados a medida que avanzábamos en la problematización de nuestro corpus sirvieron pues de estímulo para integrar y transponer algunos conceptos y herramientas teóricas tomados principalmente de la teoría de los campos de Pierre Bourdieu, del análisis del discurso a la manera de Dominique Maingueneau y de la poética histórica de los soportes tal y como ha sido desarrollada en Francia por Alain Vaillant y Marie-Ève Thérenty. Es a partir de dicho diálogo que podemos hoy afinar ciertos conceptos y herramientas teóricas indispensables para repensar algunos puntos ciegos de la teoría de las transferencias. [less ▲]
