    Quand la coproduction urbaine s’arrête en chemin : le cas du quartier Franc-Moisin à Saint-Denis

    No full text
    International audienceA partir d'une enquête réalisée dans un quartier populaire confronté à une rénovation urbaine, la cité du Franc-Moisin située à Saint-Denis en Seine-Saint-Denis, ce texte interroge la possibilité d'une « coproduction urbaine » : comment et à quelles conditions les acteur·ice·s d’un territoire peuvent-ils et elles produire la ville ensemble ? Quelles formes prend la coproduction urbaine ? Quels sont les leviers et les freins à sa mise en place ? Autour de quels enjeux et de quels acteur·ice·s se structure-t-elle ? À quelles conditions les habitant·e·s peuvent-ils·elles véritablement coproduire le devenir de leur quartier ? Quelle est la place des chercheur·e·s et expert·e·s, lorsqu’ils et elles sont présent·e·s, dans ces processus

    Les eaux de Larsa : stratégies d’acquisition et de gestion des ressources en eau d’une capitale de basse Mésopotamie au 2e millénaire avant n. è. (Irak du Sud)

    International audienceL’étude du système hydraulique de Larsa met en oeuvre une démarche d’archéologie du paysage depuis la photo-interprétation de l’imagerie drone et satellitaire de la micro-région, la prospection géophysique et l’étude géoarchéologique du site, jusqu’à la fouille d’aménagements hydrauliques. Une approche qui a permis d’identifier un grand nombre de canaux, des bassins de stockage incluant plusieurs réservoirs de grande capacité et des ouvrages dédiés au contrôle de l’eau (portes fluviales, digues, vannes) et à son franchissement (ponts). Ces données permettent d’appréhender le rôle de l’hydraulique dans la structure urbaine de cette capitale de 200 hectares où les usages de l’eau étaient multiples, pour les activités domestiques et artisanales mais aussi l’agriculture irriguée attestée dans deux secteurs intra-urbains, et le trafic fluvial associé au port et exploitant le réseau navigable des canaux. Le croisement des données archéologiques avec les sources textuelles met en lumière les politiques des rois de Larsa, de Gungunum (1932-1906 avant J-C) à Sin-iddinam (1849-1843 avant J-C), visant à augmenter et sécuriser la fourniture en eau de la ville

    Look-Ahead-Bench: a Standardized Benchmark of Look-ahead Bias in Point-in-Time LLMs for Finance

    No full text
    We introduce Look-Ahead-Bench, a standardized benchmark measuring look-ahead bias in Point-in-Time (PiT) Large Language Models (LLMs) within realistic and practical financial workflows. Unlike most existing approaches that primarily test inner lookahead knowledge via Q\&A, our benchmark evaluates model behavior in practical scenarios. To distinguish genuine predictive capability from memorization-based performance, we analyze performance decay across temporally distinct market regimes, incorporating several quantitative baselines to establish performance thresholds. We evaluate prominent open-source LLMs---Llama 3.1 (8B and 70B) and DeepSeek 3.2---against a family of Point-in-Time LLMs (Pitinf-Small, Pitinf-Medium, and frontier-level model Pitinf-Large) from PiT-Inference. Results reveal significant lookahead bias in standard LLMs, as measured with alpha decay, unlike Pitinf models, which demonstrate improved generalization and reasoning abilities as they scale in size. This work establishes a foundation for the standardized evaluation of temporal bias in financial LLMs and provides a practical framework for identifying models suitable for real-world deployment.

    Première proposition du modèle intégratif dynamique de la boucle traumatique du contrôle coercitif: Repérage, rupture de la boucle traumatique et restauration de l'agentivité

    No full text
    This document presents a first conceptual proposal of an integrative dynamic model of the traumatic loop of coercive control. Drawing on existing theoretical frameworks and clinical observations, the model describes the interactions between coercive control strategies, traumatic dysregulation, and the progressive alteration of victims’ agency. It highlights the role of individual, relational, and systemic factors, as well as the importance of early identification, multidisciplinary intervention, and conditions for breaking the traumatic loop. This proposal is intended as a conceptual framework to support ongoing and future empirical research on coercive control and its psychological, somatic, and social consequences.Ce document propose une première modélisation conceptuelle intégrative et dynamique de la boucle traumatique du contrôle coercitif. À partir de cadres théoriques existants et d’observations cliniques, le modèle décrit les interactions entre les stratégies de contrôle coercitif, la dérégulation traumatique et l’altération progressive de l’agentivité des victimes. Il met en évidence le rôle des facteurs individuels, relationnels et systémiques, ainsi que l’importance du repérage précoce, des interventions pluridisciplinaires et des conditions nécessaires à la rupture de la boucle traumatique. Cette proposition vise à constituer un cadre conceptuel destiné à soutenir des recherches empiriques en cours et à venir sur le contrôle coercitif et ses conséquences psychologiques, somatiques et sociales

    Drivers of alpine-treeline-ecotone dynamics in the Pyrenees

    International audienceAimWhile alpine-treeline ecotones are expected to shift upwards and densify under climate warming, observed dynamics vary across mountain ranges. Most studies focus solely on elevational shifts, yet different dimensions may respond to different drivers—limiting our ability to predict ecosystem responses. We examined multiple aspects of treeline ecotone changes (elevational shifts, spatial-pattern changes, and infilling) in the temperate mountain range of the Pyrenees, focusing on the eastern French sector, and uncovered interactions between climate, topography, land use, and lithology at different spatial scales.MethodsWe studied 626 treeline ecotones in the eastern French Pyrenees to examine elevational shifts, spatial-pattern changes, and infilling in relation to climate, land-use, and habitat drivers. Regression and factorial analyses identified key drivers and recurrent environmental combinations affecting treeline ecotone dynamics.ResultsThree environmental clusters revealed contrasting regional dynamics across the eastern French Pyrenees. Western treeline ecotones showed the strongest upward shift, central treeline ecotones exhibited the highest local infilling, and eastern high-elevation treeline ecotones displayed downward shift and diffuse patterns. Overall, local topography influenced fine-scale infilling, while regional land-use and biogeographic contexts controlled broader treeline ecotone elevational shift, highlighting how different drivers operate at multiple spatial scales.ConclusionUnderstanding the effects of climate change requires considering multiple dimensions beyond elevational shifts, as each aspect of treeline ecotone dynamics responds differently to drivers operating at different spatial scales. Management strategies should adapt to multi-scale contexts rather than uniform approaches, particularly where treeline ecotone structure indicates scale-dependent processes

    The Game of the Name: A Fundamental Analysis of the Institution of Names

    No full text
    International audienceThe fact that we all have names makes naming an ubiquitous institution. We develop a game-theoretic model to explain the existence of single names (anthroponyms) and how they may be exchanged as a way to promote cooperation. In social interactions, names provide partial identification information that can help reduce the likelihood of cheating, which would be higher with alternative information structures. We then propose a definition of honor based on the probability of being cheated, and derive general patterns for optimal naming that may maximize honor

    A Justice Rendered by Women for Women? What Judicial Intervention does to the Gender Gap

    No full text
    International audienceThis paper examines the influence of judges' gender on decisions in marital separation cases in France. Using detailed data on both judges and cases, we do not detect significant differences between male and female judges regarding child custody or child support. However, female judges grant significantly higher compensatory allowance compared to their male counterparts. Regardless of the dispute type, female judges do not render decisions closer to the demands of either female or male litigants than male judges do. Despite evidence that women judges are more sensitive to inequalities within couples than male judges, the effects of judicial decisions do not compensate for the inequalities created at the time of separation to the detriment of women. This is not due to judicial discretion but rather from the claims presented by litigants and the weight that judges assign to these claims in their decision-making processes. This paper thus challenges the notion of a feminine and therefore feminist justice, which would be "rendered by women for women.</div
