SUMMARY:CERNA Research Seminar will welcome Maximilian Schaefer (IMT)
DESCRIPTION:Dear all\, \nWe are pleased to announce that Maximilian Schaefer (IMT) will be the next speaker in our CERNA Research Seminar. The seminar will take place Thursday (not Wednesday this time) May 7\, 2026 at 4 PM in Salle Chevalier. \nMax will present his paper: \nGenerative AI and the Division of Labor in Knowledge Work \nOpen source development is a key input to collective innovation and production of digital commons. Generative AI coding assistants are reshaping how developers write and maintain code\, while major digital firms have expanded their open source footprint\, altering the balance between corporate and community participation. This paper studies how the release of ChatGPT-3.5 in November 2022 modified the patterns of open-source activity and whether these changes differed between institutional (firm-linked) and independent developers. Using data on 1M GitHub developers and their activity on the platform\, we classify contributors as institutional or independent and estimate a difference-in-differences model with two-way fixed effects. We find that public open source activity declines after the AI shock\, as measured by the number of public repositories per developer\, while surviving projects tend to be of higher quality: they receive more stars\, are more likely to be outgoing forks\, and show higher contribution volumes. Institutional developers reduce their public footprint more intensely but experience larger gains in visibility and quality. \nThere will be an opportunity to schedule individual meetings and/or join dinner with Max before the seminar. \nPlease enter your preferred time slot here

SUMMARY:Abundance and dependence\, extraction and restriction.
DESCRIPTION:Photo credit: Alexander Stielau. Energie. CC BY-NC-SA 2.0 \n\n\n\n\n\nThe context of the war in Iran is once again shining a spotlight on Western countries’ energy dependencies\, even as the debates on sufficiency launched four years ago at the start of the war in Ukraine appear to have had only limited impact on consumption patterns. These complex effects of resource supply tensions on consumption are also illustrated by other recent events\, beyond energy issues per se. For instance the spectre of fertiliser shortages linked to the disruption of international trade is reinforcing growing long-term concerns about food sovereignty in a country like France\, which used to see itself as a major agricultural nation. The North-South inequalities underpinning the consumption of a whole range of products (coffee\, palm oil\, soya\, but also carbon offsetting\, etc.) can be ignored less and less as the political underpinnings of the construction of transnational supply chains become visible. To what extent do these phenomena challenge the contemporary analysis of the link between consumption and the markets that sustain it? \nTaking stock of the renewed focus on tensions within resource supply chains and their effects on consumption\, the seminar aims to foster dialogue between two academic strands concerned with the connections between the worlds of production and everyday consumption\, and their political implications: the theory of practices and the social study of markets. \nPractice theory and the sociology of markets share a common commitment to the empirical grounding of their work and the importance accorded to materiality\, moving away from the symmetrical programmatic monoliths of structures  \n\n\n \n\n\nversus the individual. Much work within the theory of practices has focused on sustainable consumption and has shown how the very nature of practices—far more than individual choices\, their synchronisation and their interconnections—explains levels of consumption of water\, energy and digital services\, for example\, and creates collective dependencies that are highly resistant to attempts at change. The concept of ‘demand’ (for energy\, water\, materials\, land\, etc.)\, often invoked by public policymakers and industry\, has\, from this perspective\, been the subject of in-depth examination\, revealing that it is an ‘outcome’ of social practices rather than a starting point (Rinkinen\, Shove and Marsden\, 2020). ‘Demand’ has also been of interest to market sociology\, which\, through numerous case studies\, has highlighted the circular relationship it maintains with supply. Viewed from this perspective and situated within the context of an economy based on mass consumption\, green consumption appears\, at first glance\, to be ineffective in addressing environmental challenges (Dubuisson-Quellier\, 2022). Research on political consumption\, and ‘contested’ or ‘concerned’ markets\, has shown how consumption is embedded in collective dynamics\, conflicts and negotiations that extend beyond the mere completion of transactions\, and conversely\, how these can sometimes also serve as instruments of governance. \nThis seminar invites an open discussion on these issues. We will invite two specialists\, Elizabeth Shove and Sophie Dubuisson-Quellier\, to share their views before opening the floor for comments and discussion.  \n\n\n\n\n\nDubuisson-Quellier\, Sophie. 2022. « How does affluent consumption come to consumers?

SUMMARY:Seminar ‘Architecture and maintenance\, what we care about’
DESCRIPTION:‘Architecture and maintenance\, what we care about’ \nsession #13 \n Flying with the flow: The evolving landscape of maintenance \nat airport facilities \n  \n  \nwith Céline Ciman and Hubert Fontanel-Ngo\, Aéroport de Paris Real Estate Division \n  \nWhen it opened in 1961\, Orly Airport amazed the public as a ‘future made real’\, in the words of urban planner Nathalie Roseau. Half a century later\, the airport is welcoming the new Cœur d’Orly walkway: a high-tech structure with a futuristic design whose seamless steel tubes rise to the challenges of strength\, lightness and durability. \nBeyond the symbol of modernity turned towards an unchanging horizon\, how can structures be made to last when they evolve in response to the flow and intensification of use? How is the transition negotiated from projects that combine innovation and technical sophistication to practical concerns about their maintainability\, and with whom? \n  \nParticipation is free but registration is required. Please register here.\nAttendance is limited. Kindly let us know if you are unable to attend. \nThe seminar will be held in French. \n  \nFind out more about the seminar program and objectives
