Le déploiement d'un pilotage stratégique des coûts dans les services informatiques de deux groupes internationaux : perspective instrumentale et anal…

2011

This article analyses the strategic cost management stream with an instrumental point of view and two case studies. We try to show in what extend the Activity-based Costing developments could be included in a strategic approach of the management accounting and to test if the ABC is a relevant tool to drive the strategy. The first part synthesizes the strategic cost management developments which try to improve the Activity-based Costing method. In the first part, we describe them using the Strategic Management Accounting stream, with a link with cost management and ABC. The second part exposes a taxonomy of the reasons why using the ABC method. In a third part, we confront our developments t…

Photo-thermal control of surface plasmon mode propagation at telecom wavelengths

2016

Surface plasmon polaritons (SPPs) is the promising versatile platform proposed for guiding electromagnetic waves at nanoscale dimensions. In this context dynamic control of SPPs prop- agation is of paramount importance. Thermo-optical (TO) effect is considered as an efficient technique for performing active control of plasmonic devices. Among the thermo-optical based plasmonic devices demonstrated so far TO coefficient is dominantly provided by a dielectric material on top of the metal sustaining the SPP mode, however, the role of TO properties of the metal has been rarely investigated for plasmonic applications especially at the telecom frequency ranges. Therefore, the aim of this thesis i…

Les dispositifs de prise en charge de la difficulté scolaire à l’école élémentaire : étude de leur fonctionnement et de leurs effets sur la réussite …

2018

With the Jules Ferry laws ensuring free and compulsory schooling, equal chances of succeeding were expected in a meritocratic established school system. Reality proved otherwise: attending school still does not allow all schoolchildren to progress in the same way, as some of them encounter difficulties from the beginning. The struggle against academic failure cannot stop a considerable amount of pupils from finishing school without satisfactorily mastering the basic elements of the programmes. Moreover, recent research works have seemed to prove programmes providing assistance for underachievers to be ineffective.This thesis offers a comparative evaluation of such support systems in element…

Quand un dispositif d’accompagnement disparait : les effets sur les parcours des étudiants de santé

2023

This research is as part of current works about transition plans for students, specially medical students in France. It analyses how students make training choices as they can be given vocational guidance or not. Effects of transition programme are examined from a new point of view since we also consider results when this program doesn’t exist anymore. We can point out persistence and streams choices as main outcomes of the programme. In doing so, we highlight institutional factors in academic paths.

Microfibres for nonlinear optics

2011

In this thesis, I present my works on the fabrication, the characterization and the use of optical microfibres. Microfibres are optical fibres drawn down to sub-wavelength diameters by a temperature controlled process. Due to their small dimensions, microfibers have very special properties such as a high confinement of the electromagnetic field, a enhanced non-linear coefficient and a large evanescent tail. These properties are studied in the first chapter, after which a description of the techniques used for the drawing and manipulation of the microfibres is given. Next, we present our experiments on non-linear effects in silica microfibres. In particular, we show that it is possible to ge…

La préservation de l'environnement nocturne : les enjeux d'une controverse sociotechnique

2013

This communication explains the birth of an environmental problem, light pollution, understood as a socio-technical controversy. Over forty years, in support of the actor-network approach, it traces the conditions of its emergence, transformation and dissemination to local, national and transnational levels, and through various professional disciplines. Schematically, "environmentalists" uphold a holistic approach of "nocturnité" and define artificial light as a pollutant. Facing them, the "technicist" defend a segmented approach and define artificial light as a nuisance. The implementation of this controversy on the political agenda leads to institutional decisions that grasp it with diffi…

"C'est pas pour nous normalement". La médiation culturelle et les non-publics

2014

International audience; L'article porte sur les non-publics, ces personnes en situation à l'instant t de non-pratique culturelle, de non-contact avec un objet culturel précis. A travers une étude de cas (la réception d'une pièce de théâtre participatif par un groupe de migrants), il montre comment des dispositifs institutionnels de médiation produisent, dans des contextes précis, la distance à la culture que les institutions en charge des politiques culturelles tentent d'abolir.
