L'approche méso de l'économie sociale et solidaire : vers un nouveau paradigme ?
No full textPour saisir les dynamiques et reconfigurations en ESS (économie sociale et solidaire), il apparait nécessaire de mobiliser un cadre d'analyse capable d'articuler les évolutions macroéconomiques et institutionnelles avec les pratiques des organisations, les jeux d'acteurs au niveau local. C'est tout l'intérêt de l'approche mésorégulationniste, à laquelle se consacre ce dossier
Habiter la ville en décroissance, la transformer sans la conformer : expériences dans les fissures de l'ordre urbain à Saint-Etienne
No full textInternational audienceGrande ville à histoire industrielle située à l'ombre de la métropole lyonnaise, Saint-Étienne partage avec nombre de villes petites et moyennes une trajectoire de décroissance urbaine et un certain syndrome d'invisibilité. Le détour par la situation stéphanoise peut ainsi éclairer les spécificités des expériences de l'habiter et des mobilisations dans les villes en décroissance. Notre enquête montre que les expériences de l'habiter y sont singulières - marquées notamment par la présence des espaces vides, les transformations du peuplement et la stigmatisation urbaine - et vécues différemment selon les places occupées dans la stratification sociale. Elle éclaire aussi la façon dont des collectifs d'habitants y composent avec un système de ressources et de contraintes spécifiques pour constituer les fissures de l'ordre urbain, incarnées par les espaces vacants et délaissés, en opportunités pour (re)faire la ville autrement que selon un modèle entrepreneurial de production de l'espace
Reconstruction dentaire 3D haute fidélité par fusion de scans intra-oraux et de données CBCT via des représentations implicites profondes
No full textInternational audienceHigh-fidelity 3D tooth models are essential for digital dentistry, but must capture both the detailed crown and the complete root. Clinical imaging modalities are limited: Cone-Beam Computed Tomography (CBCT) captures the root but has a noisy, low-resolution crown, while Intraoral Scanners (IOS) provide a high-fidelity crown but no root information. A naive fusion of these sources results in unnatural seams and artifacts. We propose a novel, fully-automated pipeline that fuses CBCT and IOS data using a deep implicit representation. Our method first segments and robustly registers the tooth instances, then creates a hybrid proxy mesh combining the IOS crown and the CBCT root. The core of our approach is to use this noisy proxy to guide a class-specific DeepSDF network. This optimization process projects the input onto a learned manifold of ideal tooth shapes, generating a seamless, watertight, and anatomically coherent model. Qualitative and quantitative evaluations show our method uniquely preserves both the high-fidelity crown from IOS and the patient-specific root morphology from CBCT, overcoming the limitations of each modality and naive stitching
Les tragédies de Staël à l’épreuve de la Révolution
No full textInternational audienceIn the time of the French Revolution, Germaine de Staël wrote five tragedies, a corpus which was never performed in the public sphere and remained partly unpublished for a long time. This paper links these plays with Staël’s moral and anthropological theory, in her treatise De l’influence des passions (1792-1796). In her plays, male and female characters are constructed on distinct emotional poles and virtue is sublimated by death. Staël’s tragedies appear as a fictional place in which the writer reflects on the history of her time.À l’époque de la Révolution française, Germaine de Staël écrivit cinq tragédies, corpus qui n’a jamais été représenté sur une scène publique et est resté longtemps en partie inédit. Cet article relie ces pièces à la pensée anthropologique et morale de Staël dans son traité De l’influence des passions (1792-1796). Dans ses pièces, hommes et femmes sont construits sur des pôles émotionnels distincts et la vertu est sublimée par la mort. Les tragédies de Staël sont un lieu fictionnel où l’autrice pense l’Histoire de son temps
Chinese Grafts in urban production: Perspectives from Cambodia and Thailand
No full textInternational audienceAgainst dominant arguments about a distinctive Chinese urbanism taking shape along the corridors of the Belt and Road Initiative, we argue that Chinese transfers in urban production of Southeast Asia depend on the national and local temporalities of urban and infrastructure development and relate to infrastructure-driven strategies for regional integration. Drawing on a comparison between case studies located in Cambodia and Thailand, we show how Chinese actors are not in a position of control over urbanization processes. Rather, ad hoc arrangements are produced that allow for Chinese transfers to be grafted: into the transitioning urban fabric, onto consortia of actors, development strategies, and programs. The metaphor of the graft helps us analyse how a diversity of Chinese transfers are situated and intertwined along a spectrum that goes from the shiny, flagship projects of the BRI to the shadowy, informal and even illegal, investments in the industrial and construction sectors
How group deliberation shapes distributional preferences: An experimental analysis
No full textInternational audienceThis paper investigates how group deliberation changes individual distributional preferences. We experimentally assess the relative contribution of persuasion, social identity, and social comparison to shifts in preferences following deliberation. In a controlled setting, participants engaged in ten minutes of non-binding written group deliberation about distributional choices. Post-deliberation preferences became significantly more egalitarian than pre-deliberation ones. This within-subject preference shift is supported by a between-subject comparison showing that group deliberation has a larger egalitarian effect than individual deliberation. What explains this egalitarian shift? Our findings suggest that social identity formation is the primary but not unique driver of the change in preferences. Social identity appears to largely explain the pronounced egalitarian shift among participants who lose from equality, while persuasion and social comparison seem to account for the preference changes among those whose material payoffs are unaffected by the distributive outcome. These findings have important implications for the elicitation of distributional preferences and for the design of communicative institutions that precede collective decision-makin
Heat Acclimation During the Third Week of a Live-High-Train-High Training Camp Does Not Impair the Hematological and Perceptual Responses to Altitude.
No full textInternational audienceThis study investigated whether implementing heat training during the final week of a 3-week altitude training camp affects the hematological adaptations and variables monitored during chronic hypoxia. Twenty-three well-trained triathletes (19 males, 4 females) underwent 21 days of altitude training camp in spring (Live-High-Train-High, 1850 m). From day 14 to day 21, participants were split into two groups: a control group (HYPOXIA), which remained in the same condition, while the second group (COMBINED) had a ~1 h cycling session per day conducted in the heat (36°C ± 1°C, 40% ± 5% RH). Training load was the same for both groups. Hematological responses (including hemoglobin mass (Hbmass) and plasma volume (PV)) were assessed. Monitoring included physiological responses at rest (nocturnal oxygen saturation (SpO2) and heart rate, Hooper and Spiegel questionnaires, hydration status) and during exercise (incl. power, SpO2 through 45 min cycling at fixed heart rate). Both Hbmass (3.2% ± 3.1% for HYPOXIA, 3.7% ± 2.9% for COMBINED, p < 0.001) and PV (p = 0.003) increased during the camp, without interaction between groups (p ≥ 0.266). Exercise SpO2 decreased between the end of the second and the third week (p = 0.034, d = 0.583) in the COMBINED group. No difference between groups was detected for the other physiological or perceptual parameters. Adding heat training during the third week of an altitude training camp did not affect the increase in Hbmass or monitoring variables at rest. However, it did not confer any additional PV expansion and was associated with a reduced exercise SpO2
Evaluation of functional deficits using the Ankle‐GO™ score before and after arthroscopic anatomic lateral ankle ligament reconstruction among patients suffering from chronic ankle instability
No full textInternational audienceAbstract Purpose To evaluate the evolution of ankle deficits in patients suffering from chronic ankle instability (CAI) following an arthroscopic anatomic lateral ankle ligament reconstruction (AALALR) based on Ankle‐GO™. Methods This prospective cohort (2022–2023) included patients suffering from CAI who underwent an AALALR. The primary outcome was the evolution of ankle deficits at 5 months postsurgery, assessed using the Ankle‐GO™, which includes the modified Star Excursion Balance Test (mSEBT), Figure‐of‐8 Test (F8T), Side Hop Test (SHT) and Single‐Leg Stance Test (SLS), the Foot and Ankle Ability Measure (Foot and Ankle Ability Measure—Activity of Daily Living [FAAM‐ADL] and Foot and Ankle Ability Measure—Sport [FAAM‐Sport]) and the Ankle Ligament Reconstruction–Return to Sport after Injury (ALR‐RSI) scale. Secondary outcome was the return to sports (RTS). Factors influencing lower postoperative Ankle‐GO TM were evaluated. Results Fifty patients (mean age 29.8 ± 11.1 years) were included. The Ankle‐GO™ score increased significantly from 8.2 ± 4.7 to 13.9 ± 5.4 at 5 months postoperatively ( p < 0.01; r = 0.80). Among the individual components, ALR‐RSI showed the greatest improvement, rising from 28.0% to 69.0% ( p < 0.01; r = 0.86), followed by FAAM‐Sport (56.5%–80.1%; p < 0.01; r = 0.71). The FAAM‐ADL score increased significantly from 82.4% to 91.8% ( p < 0.01). The F8T did not improve significantly ( p > 0.05). At 5 months, 35 patients (70.0%) had returned to sport, although only 11 (31.4%) had resumed at their pre‐injury level. Preoperative Ankle‐GO™ was lower in patients not returning to sport (6.4 vs. 9.1; p = 0.04). Conclusion This short‐term study confirmed that the Ankle‐GO™ score effectively tracks recovery following AALALR. The score reflects improvements in both static and dynamic stability as well as psychological readiness. Additionally, preoperative scores were found to predict a patient's ability to RTS.

La prédication de Thomas d'Aquin — Présentation: Avec l’édition des sermons d’Étienne Tempieret de son frère Jean, o. p., par Iacopo COSTAet la bibliographie complète du Père L. J. Bataillonsuivie de témoignages sur le Père L. J. Bataillon
No full textHistoire de la prédication médiévaleInternational audienceLike most of his contemporaries, Saint Thomas does not seem to have been concerned with publishing his sermons, writes Father Louis Jacques Bataillon, who has reached the pinnacle of his research on medieval preaching in all its breadth. The fragmentary transmission of Thomas Aquinas' sermons is therefore not an exception for his time, and the edition produced by Fr. Bataillon thus serves as a model for the publication of other medieval preachers. This book first brings together eight articles devoted to the edition of Thomas Aquinas' sermons and his preaching as a whole; followed by a tribute in the form of the publication of six sermons by the brothers Étienne and Jean Tempier, edited by Iacopo Costa; this tribute continues in the complete bibliography of Fr. Bataillon, compiled from his own archives; the collection concludes with three texts delivered at Fr. Bataillon's funeral.Comme la plupart des maîtres ses contemporains, saint Thomas ne semble pas s'être préoccupé de donner une édition de sa prédication, écrit le P. Louis Jacques Bataillon, arrivé au sommet de ses recherches sur la prédication médiévale dans toute son ampleur. La transmission fragmentaire des sermons de Thomas d'Aquin n'est donc pas une exception pour son époque et l'édition qu'en a procuré le P. Bataillon constitue ainsi un modèle pour l'édition d'autres prédicateurs médiévaux. Ce livre rassemble, d'abord, huit articles consacrés à l'édition des semons de Thomas d'Aquin et à l'ensemble de sa prédication ; suit, en forme d'hommage, la publication de six sermons des frères Étienne et Jean Tempier par les soins de Iacopo Costa ; cet hommage se prolonge dans la Bibliographie complète du P. Bataillon, rédigée à partir de ses propres archives; le recueil s'achève dans trois textes prononcés lors des funérailles du P. Bataillo
