Accélération technologique et transformations organisationnelles dans l'industrie d'exploration-production d'hydrocarbures

2000

The upstream oil and gas industry experienced a dramatic technological acceleration in the early 1970's. The relationships between the agents in this industry have themselves undergone deep changes since that date. This thesis shows that a tight link exists between the technological acceleration and the organizational transformations in the upstream oil and gas industry. In a first part, it focuses on the economic theory's developments concerning industrial organization. In a second part, it applies these developments to three types of relations: those between the owner-states of hydrocarbon resources and the international petroleum companies; those between the international petroleum compa…

Les inégalités sociales à l'école : la théorie sociologique à l'épreuve des faits

1998

International audience; L'auteur esquisse une analyse de la manière dont les principales données factuelles concernant les inégalités sociales à l'école peuvent être éclairées par deux grandes perspectives théoriques : l'une met en avant l'héritage culturel familial plus ou moins adapté aux exigences de l'école, l'autre explique les choix en matière d'options et d'orientations comme les résultats de calculs rationnels effectués par des "acteurs stratèges".

Paradoxical social representations of linky smart meters and privacy paradox

2021

Consumer participation to electricity consumption reduction (ECR) has become a major challenge in a context of Energy Transition. The Linky french Smart Meter, which use contributes to ECR, is confronted to many controversies reflecting the social legitimation at stake which underlies its evaluation. This article proposes to study privacy paradox regarding Linky Smart Meter use, mobilizing the conceptual background of consumer psychological empowerment. In that aim, a social representation analysis was conducted involving 271 respondents. Results highlight, on one hand, a privacy paradox involving 3 out of the 4 dimensions of psychological empowerment, and on another hand, the presence of m…

A fuzzy-logic-based controller for methane production in anaerobic fixed-film reactors

2017

The main objective of this work was to develop a controller for biogas production in continuous anaerobic fixed-bed reactors, which used effluent total volatile fatty acids (VFA) concentration as control input in order to prevent process acidification at closed loop. To this aim, a fuzzy-logic-based control system was developed, tuned and validated in an anaerobic fixed-bed reactor at pilot scale that treated industrial winery wastewater. The proposed controller varied the flow rate of wastewater entering the system as a function of the gaseous outflow rate of methane and VFA concentration. Simulation results show that the proposed controller is capable to achieve great process stability ev…

Ethics in military organisations : implementation in the battlefield and lessons for management sciences

2016

This research questions the idea of military ethics. Our work uses an analytical framework combining three different disciplines: Ethics of care, developed in moral philosophy, Stakeholder theory, from business ethics, New institutionalism theory, from management science. This framework is then applied on two different research fields: the first one deals with the study of battles where ethical stakes were particularly high: the battle of Alger, the Iraqi war, the Srebrenica battle.The second one is qualitative interviews with officers coming back from the battlefield: 10 US officers from the Iraqi conflict and 7 French militaries from Afghanistan. These two research fields are completed by…
