Public Persuasion
No full textThis short paper studies the problem of public persuasion, that is, when a sender has to persuade multiple receivers, possibly having heterogenous beliefs, with the same information for all. We show that public persuasion constrains the sender in how he can influence the beliefs of receivers: if the sender wants to influence the beliefs of one particular receiver, he loses all controls over the beliefs of the others
Self-employment, health, and health care: When the going gets tough, the tough get going?
No full textInternational audienceThis study provides a life-course analysis of the relationship between self-employment, health, and health care use among individuals aged 50 and older in Europe. Using data from the Survey of Health, Ageing, and Retirement in Europe (SHARE), we apply first-difference and dynamic panel data models that go beyond standard approaches in mitigating endogeneity concerns. Our findings show that the self-employed enjoy better health at younger ages, consistent with a selection effect. In addition, they experience a steeper decline in physical health over time. We also document two distinct phases of health care use: during working life, the self-employed are more likely to be hospitalised, suggesting delayed care until acute needs arise; after retirement, the number of medical visits increases, consistent with a lower opportunity cost of care
Plurals, mass nouns and reference: philosophical issues
No full textHow do plurals and mass nouns refer? What kind of logic should be used in order to account for the truth-conditions of the sentences they appear in? For linguists, first-order predicate logic is adequate, provided it is supplemented by a notion of mereological sum for plurals and for mass nouns. On the contrary, according to some philosophers, new logics must be used, plural logic for plurals and mass logic for mass nouns. We survey these debates in this entry.</div

Compte-rendu de « Emmanuelle Reungoat et François Buton (dir.), Idées reçues sur les Gilets jaunes. Un marqueur des luttes sociales contemporaines (Le Cavalier bleu, 2024) »
No full textNational audience« Publié plus de cinq ans après le surgissement des Gilets jaunes en novembre 2018, cet ouvrage collectif dirigé par Emmanuelle Reungoat et François Buton s’inscrit dans la démarche durkheimienne qui exige de rompre avec les prénotions en passant les idées reçues sur ce mouvement au crible d’enquêtes approfondies fondées sur des monographies de terrain, des entretiens biographiques, des questionnaires ou des échantillons représentatifs. Fruit de l’engouement des chercheurs en sciences sociales pour les Gilets jaunes, il réunit les contributions de vingt-sept politistes, sociologues, historiens, géographes et anthropologues. Il articule des travaux de doctorants consacrés aux Gilets jaunes et des analyses d’universitaires confirmés qui appréhendent le mouvement au prisme de leur objet d’étude antérieur. La thèse selon laquelle “les Gilets jaunes sont bien un mouvement social, et un mouvement pas comme les autres” (p. 19), qui marque l’histoire des luttes sociales, structure cet ouvrage composé de trois grandes parties.
Mezanno : des sources sérielles aux données structurées pour les humanités numériques
No full textNational audienceThis paper presents Corpusense, a tool developed within the Mezanno program and supported by the bibliothèque nationale de France (BnF) as part of its four-year research plan. Mezanno aims to provide an open-source software solution to address the lack of integrated tools that enable social sciences and humanities (SSH) researchers to produce large volumes of structured data from digitized historical sources. Building on this specific use case, our approach differs from existing platforms by prioritizing user autonomy and ensuring interoperability among various tools and models for information extraction and structuring. We then describe Corpusense in more detail and show how it functions as a central interface in this ecosystem. We evaluate the proposed tools on early 20th-century cinema directories and discuss the main challenges that guide our ongoing work.Nous présentons l’outil Corpusense, développé au sein du programme Mezanno et soutenu par la Bibliothèque nationale de France (BnF) dans le cadre de son plan quadriennal de la recherche. Mezanno vise à proposer une solution logicielle libre et ouverte pour combler le manque d’outil intégré permettant aux chercheurs-ses en SHS de produire en grande quantité des données structurées à partir des sources historiques numérisées. Partant de ce cas très spécifique, notre démarche se démarque des plateformes existantes en tentant de maximiserl’autonomie des utilisateurs et l’interopérabilité de différents outils et modèles d’extraction et structuration d’informations. Nous présentons alors plus spécifiquement l’outil Corpusense qui sert d’interface pivot dans cet écosystème. Nous évaluons la pertinence des outils proposés sur un cas d’annuaires du cinéma du début du XXesiècle, ce qui nous permettent d’identifier les principaux défis qui guident notre travail actuel
Realized drift
No full textInternational audienceDrift and volatility are two mainsprings of asset price dynamics. While volatilities have been studied extensively in the literature, drifts are commonly believed to be impossible to estimate and largely ignored in the literature. This paper shows how to detect drift using realized autocovariance implemented on high-frequency data. We use a theoretical treatment in which the classical model for the efficient price, an Itō semimartingale possibly contaminated by microstructure noise, is enriched with drift and volatility explosions. Our theory advocates a novel decomposition for realized variance into a drift and a volatility component, which leads to significant improvements in volatility forecasting
The Philosophical Colony: Writing the History of Philosophy in the Eighteenth and Nineteenth Centuries. Transl. by Adrian Morfee
No full textInternational audienceIn the eighteenth and nineteenth centuries, ethnologists, linguists, historians, and especially historians of philosophy identified other “cultures,” which they distinguished from the West in order to subject them to empirical study. Consequently, Europe was conceived as the unique territory of philosophy, analytical rationality, and reflexive thinking. This book offers an interdisciplinary history of the history of philosophy and investigates how the scientific imagination was constructed in the West. It contributes to debates on the ideological assumptions and political aims of the European social sciences and humanities
