Dire l'aidance dans le cas de la maladie d'Alzheimer : du dit, du suggéré à l’impensé,
No full textInternational audience« Je ne suis pas son aidante, je suis sa femme ». Malgré une visibilité grandissante de l’aidance dans l’espace public se dire « aidant » reste compliqué. Le mot véhicule des représentations sociales empreintes de valeurs contradictoires. Dans le contexte de la maladie d’Alzheimer, il s’inscrit en plus dans un impensé culturel : celui de vivre avec une maladie qui efface progressivement l’histoire sur laquelle s’est construit le lien affectif et pourtant d’accepter le rôle d’aidant en vertu de ce lien. Le choix d’aborder l’aidance par les discours, par une analyse des mots et formulations langagières, permet de comprendre comment ces discours (re)construisent une identité dans et à travers l’aidance. Nous identifions ainsi des pratiques plus ou moins opérationnelles, des savoirs progressivement construits, mais aussi des résistances – matérielles ou subjectives – auxquelles les aidants se heurtent pour assumer les tâches nécessaires, sans négliger les sources de satisfaction ou d’insatisfaction qu’ils trouvent dans la relation d’aide. L’ouvrage, inscrit en sciences du langage, apporte un point de vue complémentaire à celui des sciences humaines et sociales sur un maillon essentiel de la chaine de soin mais encore mal connu et reconnu
« Quand les sciences de l’éducation et les sciences du langage se rencontrent pour aborder une problématique sensible : celle des étudiants-aidants »,

Advances in fungal-mediated plastic biodegradation: Mechanisms, challenges, and future directions
No full textInternational audiencePlastic pollution represents one of the most critical environmental challenges of our time, requiring innovative and sustainable waste management strategies. Among emerging solutions, fungal-mediated plastic biodegradation has gained significant attention due to the ecological versatility and strong enzymatic potential of fungi. This review synthesizes recent advances in fungal degradation of conventional plastics, such as polyethylene (PE) and polyethylene terephthalate (PET), and biodegradable polymers, including polylactic acid (PLA) and polyhydroxyalkanoates (PHA)-based polymers. Methodological approaches used to assess biodegradation, encompassing chemical, physical, and biological metrics, are evaluated to identify current limitations and biases. Despite significant progress, major challenges remain, including slow degradation kinetics, variability in environmental performance, and scalability constraints. Addressing these limitations requires multidisciplinary strategies, integrating fungal genetics, enzyme engineering, materials science, and environmental biotechnology. A key step forward lies in the establishment of a standardized, evidence-based evaluation framework, or "ladder of evidence", to rank fungal taxa, enzymatic systems, and polymer types according to their true biodegradation potential. By identifying key knowledge gaps and highlighting future research priorities, this review underscores the potential of fungal-mediated biodegradation to contribute to effective plastic waste management and mitigate the global plastic crisis

Ocean 2: A Co-designed Belmont Forum Action for Biodiversity and the Ocean We Want
No full textThe Belmont Forum fosters transdisciplinary sustainability research through its Collaborative Research Actions (CRAs). In 2018, the Oceans CRA was launched to advance knowledge and solutions for sustainable use of ocean resources, resulting in 13 multilateral projects involving researchers and societal actors from 16 countries. Building on these achievements, Ocean 2 was developed during the final phase of the Oceans CRA and endorsed as a contribution to the UN Decade of Ocean Science for Sustainable Development (2021-2030). Ocean 2 expands the scope of its predecessor by emphasizing biodiversity conservation, nature-based solutions, the integration of biodiversity with climate and ocean dynamics in line with nexus approaches sensu IPBES and the Convention on Biological Diversity’s 2050 Vision of “Living in Harmony with Nature,” and the attention to ethics, governance, and the use of scenarios as tools to foresee desirable futures for ocean biodiversity in relation to society. Here we describe the co-design process that led to the formulation of Ocean 2, an initiative of the French Alliance for Environmental Research refined through eight scoping workshops held worldwide in 2024. Two complementary formats—hybrid sessions at international conferences and fully online workshops—were used to engage researchers and societal actors across disciplines, sectors, regions and world-views. Input was synthesized to identify central themes, which informed the final Call text adopted by Belmont Forum members in 2025. The Ocean 2 CRA call was opened in June 2025, with applications due in March 2026. By combining structured co-design, global outreach, and integration with the Ocean Decade’s 10 Challenges, Ocean 2 is a step towards building inclusive, transdisciplinary, and solution-oriented research agendas for the ocean we want
ADEPT 2024 Workshop Summary
No full textInternational audienceThe Architecture Analysis and Design Language (AADL) is a SAE standard for modeling both hardware and software architecture of embedded systems. Widely embraced by stakeholders in critical real-time embedded systems, the AADL standard is used to address a large set of concerns including performance (latency, schedulability), safety, and security. The ADEPT workshop aims to present and report on current projects in the field of design, implementation, and verification of critical real-time embedded systems where AaADL is a first-citizen technology. This article is a summary of the third edition of the workshop in 2024
