Vouloir à plusieurs ? A la recherche d'une volonté collective dans les sociétés commerciales
No full text(4'369 mots ; 27'587 signes)Au titre de l’affectio societatis, le fait de vouloir entreprendre la même aventure sociale se situe au fondement d’une société commerciale. Si la capacité juridique de la personne morale découle spécifiquement de cet accord, il faudra en conclure que ce vouloir se trouve à la racine de son pouvoir. Il apparaît pourtant dans l’analyse que la volonté d’un collectif d’associés – toujours délicate à caractériser sur le terrain du droit privé – est difficilement imputable à l’entité qui les unit… Prenant garde aux abus de langage, aux raccourcis psychologiques et autres projections anthropomorphiques, il est donc intéressant d’interroger le sens de cette donnée peu contestée en droit des sociétés, qu’est la volonté propre du groupe constitué

SAGA: TRANSLANGUAGING AND SUSTAINABILITY: A Green Paper to Seed and Grow the Research Project
No full textSAGA is a 5 year research project (2023-2028) to investigate and advance sustainability transitions across language and context. The project's goal is to advance more-than-English language capacity as an overlooked means to embed diverse cultural values within more effective sustainability strategies.For some, sustainable development is an international signifier of a greener, fairer world. For others, it is an empty signifier. The fact that English is the lingua franca of sustainable development discourse and policy is one barrier to the emergence of a cultural code of sustainability that is needed for a sustainability transition. Removing this barrier requires more than rough translation; it demands adequate interpretation, contextualization, and connections to communities in place – a process of translanguaging.With reflexive, observational and collaborative investigations in English, French, Finnish, Danish, and Indigenous languages, in different urban contexts, the SAGA research team will investigate the translanguaging processes that permit and inhibit the activation of sustainable cities in ways that hold cultural meaning.We aim to crack the lived coding of sustainable cities, as opposed to their global blueprints, by inquiring into the role of language in sustainability talk and sustainability interventions in monolingual, bilingual and multilingual contexts

Building a Scalable and Coercion-Resistant E-Voting System Using Blockchain
No full textInternational audienceCoercion resistance is a strong notion of privacy, ensuring that voters cannot be forced or incentivized to reveal their votes, pre- venting vote-buying or coercion attempts. However, achieving coercion resistance while simultaneously guaranteeing election verifiability and scalability remains a significant challenge in electronic voting systems. In response to these challenges, we propose LOKI Vote, a blockchain-based e-voting protocol designed to ensure strong coercion resistance while guaranteeing all the requirements of a secure and democratic election. LOKI Vote employs advanced cryptographic mechanisms, including Zero-Knowledge Proofs, the Modified El-Gamal Cryptosystem, and BBS Group Signatures. It integrates the LLARP mix net- work, providing anonymous, low-latency communication between voters and election authorities. By leveraging blockchain technology, the system ensures immutability and public verifiability, allowing anyone to audit the process without compro- mising voter anonymity. Additionally, we conduct an informal security assessment against a list of security requirements including voters’ eligibility, fairness, verifiability and data integrity. We then formally verify the protocol’s security using ProVerif and Applied Pi-Calculus, demonstrating that it guarantees ballot secrecy, voter authentication, and vote privacy. We implement our proposed approach and evaluate its performance in terms of execution time, cost, and scalability. The results show the protocol’s efficiency. Finally, we simulate a real-world election using LOKI Vote to validate its practicality. Our findings demonstrate that it scales efficiently to millions of voters, significantly reducing vote tallying time

Upgraded decision making in continuous domains for autonomous vehicles in high complexity scenarios using escalated DDPG
No full textInternational audienceAutonomous vehicles (AVs) have gained attention for their safety enhancements and comfortable travel. Ongoing research targets improvements in AV technology, addressing challenges like road uncertainties, weather changes, and continuous state-actions. In this paper, we propose “Escalated DDPG,” an extension of the Deep Deterministic Policy Gradient (DDPG) algorithm, designed mainly for autonomous vehicle (AV) decision-making. Our novel approach tackles key challenges encountered with DDPG, including instability, slow convergence, and the growing complexity of AV environments. By upgrading action selection and learning policies based on consecutive actions and states, Escalated DDPG enhances convergence speed while maintaining a balanced exploration-exploitation trade-off. We conduct experiments in a gym environment, comparing the performance of our method with traditional DDPG. Results illustrate the superior accuracy and adaptability of Escalated DDPG in handling decision-making tasks involving continuous action and state spaces, even in complex scenarios. The findings in this paper contribute to advancing AV technology, enhancing their decision-making capabilities, and enabling more efficient and reliable autonomous driving systems
L'avenir des relations franco-allemandes: Perspectives croisées
No full textInternational audienceAlors que les conflits se multiplient dans le monde, le couple franco-allemand fait-il encore figure de moteur de l’Europe ? Plus de soixante ans après le traité de l’Élysée, qui scellait la réconciliation entre les deux pays, et alors que le traité d’Aix-la-Chapelle, conclu le 22 janvier 2019, a élargi et intensifié le champ de leur coopération, quelles perspectives se dessinent pour un avenir partagé ? Le cadre institutionnel issu des traités favorise l’action franco-allemande sur le continent, en particulier dans les domaines de l’éducation, de la sécurité et de la défense, de l’économie, de la coopération transfrontalière et du numérique. Malgré les malentendus récurrents qui fragilisent les rapports entre la France et l’Allemagne, institutions et société civile ont su se mobiliser pour développer les relations entre les deux États et faire de ces liens hors norme un véritable laboratoire pour l’Europe et pour le monde. Cet ouvrage comprenant des contributions en français et en allemand a été dirigé par Laurence Nicolas-Vullierme, maître de conférences HDR en droit privé à l’université Paris-Panthéon-Assas, et par Anne-Marie Thévenot-Werner, maître de conférences en droit public à l’université Paris-Panthéon-Assas.
