In his new book published by Princeton University Press, Michel Anteby opens the debate: how would you react to a researcher who asked you uncomfortable questions? One option is often to find ways to resist them, using every possible nuance, from categorically refusing to answer to feigning sudden memory lapses. Such behavior can ultimately delay or prevent research from being conducted in close proximity to the respondents. For Michel Anteby, however, it would be a shame to see this as nothing more than a constraint to be forgotten once access to the field is finally granted. On the contrary, the sociologist argues that it is important to take the resistance shown by respondents seriously, as it often provides valuable insights into the social worlds around us. With more than 20 years of experience in ethnography, the author helps us to reflect on this issue through a variety of research fields, from the issue of strikes at Disney to that of security at international airports, and the question of morality at a business school such as Harvard University.
The meeting will take place on Thursday, January 9, from 10 a.m. to 12 p.m. in room B 004 (Belgrand wing) of the Ecole nationale des ponts et chaussées, 6-8 avenue Blaise-Pascal, Cité Descartes in Champs-sur-Marne (RER A Noisy-Champs). It will be introduced by Stève Bernardin.

A study day featuring roundtable discussions is being organized by the École Nationale des Ponts et Chaussées on November 28, 2024, to mark the publication of the latest issue of Transitions. This issue was co-edited by Nathalie Roseau and Bruno Tassin.

Global disruptions, their speed and intensity, are forcing us to take action. Technological innovation alone and the idea of decoupling the intensity of human activities from their impact on the Earth will not be enough to make life compatible with planetary boundaries. Based on this observation, the researchers who contributed to issue 4 of Transitions believe that a major shift in production and consumption systems is unavoidable. It is even necessary in the very short term, given the alarming nature of the situation.
Climate, biodiversity, chemical contaminants, water resources: with their backs against the wall, the world of research and higher education is analyzing, examining, and communicating possible paths for socio-ecological futures. At the crossroads of the humanities, social sciences, and environmental sciences, this day is an opportunity to examine the relationship between technology and politics and possible avenues for public action, as well as to consider the implications for society of putting these transitions into practice.

Rocio Calzado Lopez and Manon Espinasse will speak at the OCS/AUSser laboratory seminar on Monday, November 18, 2024, at 6:00 p.m.
This session will take place in the boardroom (Banham space) at the École nationale supérieure d'architecture Paris-Est.
The session will open with a presentation by Rocio Calzado Lopez: "While the housing crisis is the starting point for this research, the alarming context of social housing demolitions is the subject to be examined. To discuss this crisis and examine these demolitions, this research addresses the relationship between the three dimensions of politics (politics, policy, and polity) and architecture, and questions not whether architecture is political, but rather how architecture is political. What are the material resources of a building that influence governance processes? Perhaps if we trace the political role of buildings in the decision-making behind a demolition, we could learn something new about the role of architects in the current housing crisis.
To explore this idea, I develop the biography of two housing complexes, one in Rome and the other in Paris, which were about to be demolished but instead ended up undergoing a long process of transformation. "Beyond Demolition, Caring for Architecture" is not a finished work, but an ongoing research project, tested both through a doctoral project currently underway at the LATTS laboratory at the École des Ponts et Chaussées and a documentary film produced by the film collective "docar," with the support of the Pavillon de l'Arsenal. The session will begin with the screening of several excerpts from the documentary.
It will continue with a presentation by Manon Espinasse: "The highway is an infrastructure considered essential to the functioning of our current societies and economies.
Since its inception, it has been the subject of a series of actions (repair, adaptation, regeneration, transformation) to ensure its permanence. Because it both contributes to exceeding planetary limits and is exposed to the consequences of these exceedances, it has been included in public policies for "ecological transition." The highway (as a socio-technical system) of the 21st century is increasingly "multi-functional ": a support for plural mobility (from automobility to shared mobility), a habitat for biodiversity and carbon sinks (in its dependencies and edges), a vector for renewable energy (from the highway hosting urban networks to the highway producing urban solar energy). This diversified highway is being built in the Bordeaux metropolitan area, based on the one that originated in the late 1960s. It is the result of adjustments and reconfigurations between highway planning and land-use planning (and their imaginaries) since 1967, which gave rise to specific architectural, urban, landscape, and infrastructural forms. This paper proposes to look at the early stages of the Bordeaux motorway, the genesis of the co-construction of the motorway and the metropolis, and to question the "infrastructural permanence."
In the 1960s, the highway was a local and national project, a tool for establishing Bordeaux as a balanced metropolis (DATAR) and a city with over a million inhabitants (Jacques Chaban Delmas). This highway of metropolitanization was both a means of large-scale development in the creation of Bordeaux as a metropolis (as seen in the development plans) and a means of economic development (as seen in the aerial photographs)."

The Techniques, Territories, and Societies Laboratory (Latts, UMR 8134, CNRS, École des Ponts ParisTech, Gustave Eiffel University) invites candidates for the CNRS competition (sections 36, 39, and 40, CID 52, 53, and 55) who wish to obtain its support to contact the laboratory management: Elsa Vivant (elsa.vivant@univ-eiffel.fr) and Jonathan Rutherford (jonathan.rutherford@enpc.fr).
Please send the laboratory management a document presenting the CNRS project, along with a brief CV and a letter explaining your reasons for requesting support, by December 15, 2024 at the latest.
Applications will be reviewed by the laboratory council in early January in order to issue a letter confirming their suitability for the Latts scientific project. Subsequently, for those who are eligible and wish to be assigned to Latts, support will be offered in preparation for the interview, as well as an opportunity to meet with members of the laboratory.

Summary of the original thesis “Unfaithful loyalties. Municipal political engagement through the prism of its ordinary dissonances”
The thesis opens with a puzzle posed by the latest municipal elections: the countless declarations by mayors announcing that they would not seek re-election, followed by a remarkable re-election rate. The puzzle can be solved by attributing a strategic or moral sense to the mayors; it can also be seen as the possibility of being loyal without being faithful, of remaining a practitioner while having lost faith. This interpretation opens up a reflection on the ordinary misalignments of commitment, forms of loyalty despite everything, more intermittent and ambivalent, from which it is difficult to simply infer adherence or satisfaction. Often conceptualized in terms of abnormality and psychology (such as cognitive dissonance), these misalignments are understood in the thesis as a common and ordinary component of mayors’ political commitment. They are also reinserted into social spaces and trajectories that give them varying meanings. Thus, as the reflections unfold, various ways of rationalizing and legitimizing the discrepancies inherent in political engagement emerge, that is, accepting them without necessarily seeking to reduce them.
With contributions from Noémie Suissa, Olivier Coutard, Félix Adisson, Martine Drozdz, and Nathalie Roseau.
