Musée et écologie, missions, engagements et pratiques
No full textInternational audienceFaced with the climate emergency and increasing threats to life on Earth, museums must solve a crucial equation: reducing their environmental impact while strengthening their social and cultural role. In this book, more than 80 museum professionals, scientists, and artists come together to discuss the development of strategic guidelines and eco-responsible practices. Musée et écologie (Museums and Ecology) provides an overview of the initiatives of a community committed to creating sober and socially responsible museums, and offers conceptual and practical keys for the eco-design of museums.Face à l’urgence climatique et à la multiplication des atteintes au vivant, les musées ont à résoudre une équation décisive : diminuer leur impact écologique tout en renforçant leur rôle social et culturel. Dans cet ouvrage, ce sont plus de 80 acteurs des musées – professionnels, scientifiques et artistes – qui se mobilisent et réfléchissent à la production d’orientations stratégiques et de pratiques écoresponsables. Musée et écologie dresse le panorama des initiatives d’une communauté engagée en faveur d’un musée sobre et citoyen et offre des clés conceptuelles et pratiques pour uneécoconception du musée
Panda as the flagship of China’s digital diplomacy: Rethinking the intersection of network and emotional narrative strategy
No full textInternational audienceThis chapter aims to rethink the mediated communication ontology of China’s digital public diplomacy, taking digital panda diplomacy – the most successful public diplomacy campaign of China on social media in more than a decade of digital diplomacy – as a case to identify the emotional network communication structure and narrative strategies led by Beijing, so as to serve the Communist Party of China (CPC) ’s public diplomacy goals of telling China’s stories and demonstrating positive energy towards foreign publics. Chinese media have constructed a journalistic paradigm that promotes feelings of happiness in message receivers. The online production of panda-themed news stories involves three strategies: (a) anthropomorphic rhetoric that implements human-like expressions to make pandas seem “human,” (b) visual images of pandas to mediate relevant knowledge, and (c) manipulation of panda imagery to frame political and public-diplomatic messages that endorse China and its government

Conclusion. Le ciel urbain, excroissance de la ville ou possible échappatoire ?
No full textInternational audienceDressant un bilan croisé des chapitres de l'ouvrage, la conclusion souligne l’importance des infrastructures et des savoirs et techniques des scientifiques et ingénieurs dans la reconfiguration du ciel francilien et notre rapport à lui. Elle dégage trois « figures du ciel parisien » dans le long XXe siècle : le spectacle, la poubelle et la menace. Elle invite à une réflexion sur le ciel urbain souhaité pour l’avenir, d’autant que les événements récents lui ont redonné une actualité politique certaine
Ballons, lumières, fumées… d’un siècle à l’autre, la ville à l’assaut du ciel
No full textInternational audienceÀ la fin du XIXe siècle, l’essor des techniques de télégraphie et de transport aérien transforme le ciel parisien en voie de communication. Parallèlement, objets volants, lumières et fumées deviennent omniprésents, modifiant le paysage céleste. Ce chapitre s’intéresse à cette multiplicité et aux angoisses sociales et environnementales qui y font écho, mettant en lumière l’évolution des représentations du ciel entre 1870 et le début du xxe siècle

Co-culturing with bacteria modulates fatty acid composition in benthic diatom biofilms for lipid-based biotechnologies: A case study of Amphora sp.
No full textInternational audienceDespite being recognized as promising oleaginous microalgal resources, benthic diatom biofilms remain overlooked in microalgal biotechnology. To enhance their industrial potential, bacterial interactions can exploit to boost biomass, increase lipid yields and tailor lipid profiles. Given the complexity of natural biofilms, our study adopted a reductionist approach to investigate the impact of bacteria on the metabolism of a marine benthic diatom, Amphora sp., through binary co-cultures. Bacteria were isolated from non-axenic Amphora sp. biofilm cultures during the exponential phase in a lab-scale porous substrate biofilm photobioreactor. A bacterial biofilm assay was conducted to select biofilm-forming strains, followed by co-culturing them with Amphora sp. in bottle culture flasks, assuming these strains would persist and interact within the Amphora biofilm. All cultures were maintained for 6 days in F/2-enriched artificial seawater at 16 • C, under a 12:12 light:dark cycle (100 μmol photons.m -2 .s -1 ). Biomass and lipid contents were quantified using the gravimetric method, while fatty acid profiles were analysed using GC-MS. Results showed that some bacterial strains reduced Amphora sp. biomass, while Nitratireductor sp. and Sulfitobacter sp. had no noticeable effect. However, significant shifts in fatty acid profile of Amphora sp. were observed in most co-cultures while none of the individual bacterial strains substantially affected lipid production compared to its axenic and non-axenic counterparts. Co-cultures with Nitratireductor sp. and Sulfitobacter sp. yielded 50-55 % saturated, 40-50 % monounsaturated, and 1-6 % polyunsaturated fatty acids, indicating favourable biodiesel properties. Thus, modifying the microbiome of microalgal biofilms could be an innovative strategy for tailoring fatty acid composition for lipid-based applications
