No full textReconnaissance et invisibilité : les femmes de chambre au cœur de la performance hôtelière
No full textThis thesis focuses on the profession of housekeepers in the hospitality sector, a crucial yet historically undervalued and invisible occupation. Based on a field study conducted at Whaka Lodge, a high-end outdoor hospitality establishment, the research highlights the physical and mental demands of the job, the precarious employment conditions, and the persistence of gender stereotypes that assign women to cleaning tasks. The interviews reveal both the strong commitment of employees and the lack of formal recognition, reflecting a tension between essential contribution and low visibility. These findings are analyzed in light of academic literature on gendered division of labor, professional recognition, and inclusive management. The study shows that enhancing the value of this occupation requires more than organizational adjustments: it calls for genuine acknowledgment of invisible skills and employees’ well-being. Finally, several recommendations are made to rethink managerial practices, combining recognition, participation, and quality of working life, while integrating the broader performance goals of hospitality organizations.Ce mémoire s’intéresse au métier de femme de chambre dans l’hôtellerie, un travail indispensable au fonctionnement des établissements mais historiquement invisibilisé et peu valorisé. À travers une enquête de terrain menée au Whaka Lodge, établissement d’hôtellerie de plein air haut de gamme, l’étude met en lumière la charge physique et mentale de cette activité, la précarité des conditions d’emploi et la persistance de stéréotypes de genre qui assignent les femmes aux tâches d’entretien. Les entretiens réalisés révèlent à la fois un fort engagement des salariées et un déficit de reconnaissance institutionnelle, traduisant une tension entre contribution essentielle et faible visibilité. L’analyse croise ces résultats avec la littérature sur la division sexuée du travail, la reconnaissance professionnelle et le management inclusif. Elle montre que la valorisation du métier ne peut se limiter à des ajustements organisationnels mais nécessite une véritable prise en compte des compétences invisibles et du bien-être des salariées. Enfin, des pistes de réflexion sont proposées afin de repenser les pratiques managériales, en articulant reconnaissance, participation et qualité de vie au travail, tout en intégrant les enjeux de performance globale des établissements hôteliers

Backscattering and Wireless Power Transfer in Battery-Free Sensors for Structural Health Monitoring of Reinforced Concrete Structures
No full textInternational audienceThis paper presents an overview of the use of backscattering and Wireless Power Transfer in battery-free sensors for Non-Destructive Testing of reinforced concrete in order to ensure the Structural Health Monitoring of the structure of which it is the main material. A focus will be on a generic, battery-free Sensing Node. This last meets the Simultaneous Wireless Information and Power Transfer paradigm by being wirelessly powered and communicating wirelessly -simultaneously-thanks to electromagnetic waves. The security of wireless communications is also enhanced by backscattering and encrypting the power supply wave. This Sensing Node has been used in a Cyber-Physical System, and deployed and tested in a reinforced concrete beam with a power supply range of several metres and a wireless communication range -in Bluetooth Low Energy or LoRaWAN-of at least a few tens of metres

Kähler differentials, pure extensions and minimal key polynomials
No full textInternational audienceThe main object of study in this paper is the module Ω of Kähler differentials of an extension of valuation rings. We show that in the case of pure extensions Ω has a very good description. Namely, it is isomorphic to the quotient of two fractional ideals of the value group of the valuation. This allows us to describe the annihilator of Ω and to give criteria for Ω to be finitely generated and to be finitely presented. We also discuss how to relate the module of Kähler differentials of pure extensions to minimal key polynomials
Comparison of modular multilevel and flying capacitor converters made of wide bandgap switches for new MVDC grids
No full textInternational audienceA detailed and comparative analysis of modular multilevel and flying capacitor converters (MMC and, FCC resp.) is proposed in the context of new functionalities developments for new medium-voltage DC (MVDC) grids, taking advantage of the performance and improvement perspectives offered by wide-bandgap (WBG) components. The novelties of this work lies in the generic formalism developed, which enables both structures to be compared on an equal basis, as well as facilitating access to a number of characteristics. This comparison is generalized to the number of phases, number and type of cells, and modulation index. This approach provides a clear overall understanding of the benefits and drawbacks of the two structures in terms of structure sophistication, power conversion capabilities, control complexity and operating mode freedom. The study highlights the flexibility and the greater power range of the MMC, despite being more complex to control and bulkier than the FCC
Bringing the campaign closer to the voters: Facebook in partisan-managed campaigning in France
No full textInternational audienceAbstract During presidential campaigns, party members often operate Facebook pages or groups concurrently with the official communications of their respective political parties. However, there is limited evidence regarding the true motivations of these partisans, and how their efforts supplement the online strategies of the parties. Our study is based on interviews conducted with party members who ran Facebook pages to support a candidate during the 2022 French presidential campaign. It sheds light on how they managed their Facebook pages, often autonomously, to serve as supplementary tools to their grassroots tactics and ultimately to bring the campaign closer to the voters. This finding highlights the emergence of a hybrid model of online campaign organization, the partisan-managed campaigning model, which challenges both the traditional top-down model, in which the campaign is managed by the central party, and the more recent citizen-initiated campaign model
Taming the Triangle: On the Interplays between Fairness, Interpretability and Privacy in Machine Learning
No full textInternational audienceMachine learning techniques are increasingly used for high-stakes decision-making, such as college admissions, loan attribution or recidivism prediction. Thus, it is crucial to ensure that the models learnt can be audited or understood by human users, do not create or reproduce discrimination or bias, and do not leak sensitive information regarding their training data. Indeed, interpretability, fairness and privacy are key requirements for the development of responsible machine learning, and all three have been studied extensively during the last decade. However, they were mainly considered in isolation, while in practice they interplay with each other, either positively or negatively. In this survey paper, we review the literature on the interactions between these three desiderata. More precisely, for each pairwise interaction, we summarize the identified synergies and tensions. These findings highlight several fundamental theoretical and empirical conflicts, while also demonstrating that jointly considering these different requirements is challenging when one aims at preserving a high level of utility. To solve this issue, we also discuss possible conciliation mechanisms, showing that a careful design can enable to successfully handle these different concerns in practice
