Constitutionalism, understood as a means of establishing a political autonomous from society, is seen as having constructed the opposition between the State and society. At the same time, the concept of constitutionalism is increasingly being used to describe other forms of social power and normativity – such as the economy, finance, digital, technologies, media, environment – even though the concrete and theoretical implications of these shifts have not always been fully clarified. More recent trends have emerged within the framework of socio-constitutionalism or societal constitutionalism to challenge the reduction of constitutional issues to state-individual relations, acknowledging the complexity of power. Despite their heterogeneity in assumptions, as well as in their descriptive, normative, and theoretical dimensions, these approaches have contributed to renewing the inquiry into the relationship between constitution and society. The purpose of the conference is to assess the current boundaries of constitutionalism and to explore theoretical proposals seeking to overcome them. These approaches raise several fundamental questions: What role should be granted to social actors and sectors within constitutionalism? How can their normative autonomy be acknowledged while also regulating their private power and expansionist tendencies? To what extent do these transformations challenge traditional forms of politics? At what cost might the relationship between constitution and society be reconsidered today?  Program January 299:00 a.m. Welcome9:30-10:00 Introduction: Manon Altwegg-Boussac (Paris-Est Creteil University/IUF) and Sabina Tortorella (MSCA/University of Namur)From State to Society: New Challenges for ConstitutionalismChair: Isabelle Aubert (Paris Panthéon-Sorbonne University)10:00-10:30 Thomas Boccon-Gibod (Grenoble Alpes University): Relationships between Constitution and Society10:30-11:00 Simone Mao Zhenting (Harvard University): Constitutionalizing Society in an Age of Fragmented Authority: From State-Centrism to Social Constitutional Norms11:00-11:30 Discussion11:30-12:00 Coffee Break12:00-12:30 Angelo Jr Golia (Luiss Guido Carli): Societal Constitutionalism and General Theory of Law (beyond the State): Norm, Order, Interpretation12:30-12:45 Discussion12:45-14:30 LunchMoving Beyond the Nation-State: Theoretical PerspectivesChair: Eleonora Bottini (Sciences Po)2:30-3:00 p.m. Jean-François Kervégan (Paris Panthéon-Sorbonne University): Politics below and beyond the State: Schmitt and Kojève in Comparative Perspective3:00-3:30 p.m. Paul Linden-Retek (University at Buffalo School of Law): Postnational Society and its Law3:30-4:00 Discussion4:00-4:30 p.m. Coffee BreakNew Conceptual Tools: Alterity and DerogationChair: Eleonora Bottini (Sciences Po)4:30-5:00 p.m. Horatia Muir Watt (Sciences Po): On the Borderline (and beyond the State): Ontologizing Alterity on the Terms of the Law5:00-5:30 p.m. Raffaele Bifulco (Luiss Guido Carli): Derogation as Legal Response to Social Differentiation5:30-6:00 p.m. Discussion6:00 p.m. DinnerJanuary 309:00 a.m. WelcomeMapping Sectoral Constitutions: Case StudiesChair: Sabina Tortorella (MSCA/University of Namur)9:30-10:00 Francesco Martucci (Panthéon-Assas University): Trust and Distrust.

After a presentation of the book, Déborah V. Brosteaux will be interviewed by Thibault De Meyer and Vivien Giet.Free admission. Everyone is welcome.Book presentationFaced with the wars in which European countries are involved, we constantly oscillate between numbness and frenzy. Some war situations give rise to emotional heatedness, a "renewed" psychic and social energy, while others are barely mentioned, relegated to the background. This philosophical investigation delves into the ambivalence of our relationship to war, which is at the heart of the sensitive history of modernity.Inspired by the writings of Walter Benjamin, W. G. Sebald, and Klaus Theweleit, the book explores these warlike emotions throughout the 20th century and questions their legacy: the coldness of distancing, the denial of the ruins after 1945, the desire to intensify the experience of self, which mobilized the imagination in 1914-1918 and was swallowed up in the trenches... even mutating into fascist passions that actively fed on the devastation.Déborah V. Brosteaux takes these desires seriously, including their appeal. And she asks: what emotional transformations can be activated to resist the mobilization of war?  More information about the ARCADIE Center

Abstract Since its emergence in 1996, the Asian H5 Goose/Guangdong (Gs/Gd) lineage has circulated widely in poultry in southern China, spilling over to wild birds by 2002. Wild bird infections facilitated global dissemination via migratory waterfowl and repeated spillback into poultry, challenging the view that HPAI primarily arises from LPAI mutation. Subclade 2.3.4.4b emerged in Asia in 2013, reached Europe in 2016, caused recurrent epizootics, diversified into multiple genotypes, became dominant in wild birds, and shows zoonotic potential.This thesis investigates critical knowledge gaps regarding H5Nx subclade 2.3.4.4b in poultry: (1) early within-flock spread after punctual introduction in chickens, particularly during the first European epizootics; (2) influence of pre-existing immunity on silent circulation; (3) limitations in diagnostic throughput during epizootic peaks; (4) potential of environmental surveillance, including air and dust sampling; and (5) impact on egg contamination and the reproductive tract, relevant for food safety and zoonotic risk.Four main objectives were addressed: (1) development of an experimental model simulating punctual introductions and spread, comparing 2017 and 2020 strains and assessing pre-existing immunity; (2) enhancement of diagnostic capacity via alternative sampling, semi-automated RNA extraction, and high-throughput processing; (3) evaluation of air and dust sampling for virus monitoring under experimental and field conditions; and (4) assessment of egg contamination risk. Alternative sampling and environmental monitoring were also applied to Newcastle disease virus as a comparative notifiable pathogen.

The result of the historic twinning between the cities of Namur and Lafayette, the collaboration between UNamur and the University of Louisiana at Lafayette has taken on a new academic dimension in recent years. Formalized in 2022 with the signing of a framework agreement, this partnership has given rise to a mobility program aimed at strengthening the use of French and Francophonie within both universities. In 2026, this cooperation took concrete form with the arrival in Namur of William Lejeune, a second-year speech therapy student and the first Cajun student to benefit from this program, supported in particular by a grant from the Lafayette Foundation. Between cultural discovery, linguistic challenges, and academic ambitions, he recounts his experience on the other side of the Atlantic.

On February 21, the University of Namur hosted the symposium "Medicine and Literature," organized by the History of Medicine and Health Sciences Group, with the support of the Royal Academy of French Language and Literature of Belgium. Nearly 70 participants gathered at the Faculty of Medicine for a particularly open and stimulating day of reflection, devoted to the deep and ancient links between medical practices and literary creation.

Abstract Deep learning has revolutionized computer vision in recent years and has been applied to many fields. This thesis focuses on medical endoscopy, where deep learning can assist physicians in many tasks, such as navigating the lungs during bronchoscopy, assisting in the detection of lung diseases, detecting Crohn's disease from capsule endoscopy (PillCam), or automating the detection of polyps during colonoscopy procedures.This thesis, entitled From Pixels to Practice: Deep Learning for Endoscopy, explores how modern neural networks and learning paradigms can improve visual understanding in endoscopy, with the aim of contributing to computer-aided detection (CAD) systems that can be integrated into clinical workflows.This work follows an article-based structure and links methodological advances in geometric and temporal modeling to techniques for handling data scarcity and imbalance, as well as to the practical and clinical implications of deep learning for lung tumor detection, both from a clinical and practitioner perspective. The first part of the manuscript provides a common foundation for all subsequent parts. First, we present a general introduction to the field of machine learning in Chapter 1, explaining concepts such as classification, loss functions, and artificial neural networks. Next, Chapter 2 focuses on the field of deep learning for computer vision, detailing the main vision tasks, the concept of convolutional neural networks, ResNet, and U-Net. Finally, Chapter 3 describes medical imaging, with a focus on computed tomography (CT) scans and optical imaging. The second part of the thesis focuses on learning spatio-temporal representations. In Chapter 4, we use deep neural networks combining spatial features and temporal recurrence to address the problem of detecting the bronchial carina, an anatomical landmark that helps doctors navigate the lungs. By evaluating classification (ResNet-50), segmentation (nnU-Net), and recurrent (GRU) models on a bronchoscopy dataset we created, the study highlights the benefits of combining information from segmentation masks and temporal features. Chapter 5 continues the segmentation task by analyzing the extent to which rotation-equivariant U-Nets, based on E(2)-CNNs with C4, C8, and D4 symmetry groups, can improve performance when the orientation of objects in the image is arbitrary. Together, these chapters show how temporal and geometric modeling capture complementary aspects of visual structure. They further highlight that data imbalance and scarcity are recurring problems in deep learning. The third part studies learning in situations of data scarcity and imbalance. First, Chapter 6 explores supervised contrastive pre-training [1] on large, domain-close endoscopic datasets (Hyper-Kvasir [2], LDPolyp [3]), which is then transferred to smaller, disease-specific data (Crohn-IPI [4]). This methodology performs better than pre-training on ImageNet or based on cross-entropy, highlighting the value of domain-specific contrastive representations. Next, Chapter 7 introduces Mask-Aware Cropping (MAC), a new data augmentation technique that mitigates pixel-level imbalance in segmentation. On various datasets with varying imbalance regimes (URDE [5], Kvasir-SEG [6], HAM10000 [7]), MAC consistently improves Dice and IoU metrics under conditions of extreme imbalance. Together, these methods form a data-centric framework for effective learning when annotations are scarce or unevenly distributed. The fourth part of the thesis focuses on deep learning in the operating room. Chapter 8 proposes a first model (ResNet-50) for the visual detection of lung cancer in bronchoscopy, trained on real, in-vivo data. The model outperforms junior physicians, while remaining inferior to experts. This result shows that CAD systems for lung cancer detection are promising. Chapter 9 extends this work by evaluating the usability of a CAD system based on a deep learning model. Combining probability indices, temporal graphs, and saliency map overlays, a multicenter evaluation with 10 physicians is conducted. The tool received favorable feedback, with high usability (SUS score of 80.5 [8]) and strong clinical acceptance. Beyond endoscopy, the results concerning rotation equivariance and pixel imbalance can be generalized to other fields such as microscopy, dermatology, and aerial imaging. This shows that the proposed methods are applicable to visual learning under structured variability and limited data constraints.Keywords: machine learning, computer vision, medicine, endoscopy, convolutional neural networks, segmentation, recurrent models, equivariance.  Jury Prof. Bruno Dumas - University of NamurProf. Frénay Benoit - University of NamurProf. Schobbens P-Y. - University of NamurProf. Beuls Katrien - University of Namur,Dr. Benjamin Mertens - Lys MédicalProf. Oramas Mogrojevo José Antonio - University of AntwerpDr. Mancas Matei - University of Mons Register

Between the risks of “globocide” and the long-term management of nuclear waste, nuclear power embodies the anxieties of our time while remaining largely invisible in public discourse. Based on FNRS research led by Danielle Leenaerts, a lecturer in the Department of Archaeology and Art Sciences, a three-part project comprising an exhibition, a book, and an interdisciplinary study day offers a unique insight into how Belgian and international artists depict nuclear power. 

As part of its seminar, Centre Arcadie will be pleased to welcome Igor Krtolica for a session devoted to his book Romain Gary. De l'humanisme à l'écologie, Gallimard, 2025.Maître de conférences en philosophie à l'Université de Picardie Jules-Verne, junior member of the Institut universitaire de France, Igor Krtolica is the author (in addition to the work to be discussed) of Gilles Deleuze (PUF, coll. "Que sais-je? ", 2015), of Gilles Deleuze et Félix Guattari : Une philosophie des devenirs-révolutionnaires(Éditions Amsterdam, 2024) and of a commentary on an extract from Romain Gary's Les Racines du ciel entitled Antifascism, humanism and ecology (PUF, coll. "Classiques de l'écologie", 2025).After a presentation of the work, Igor Krtolica will be interviewed by Jean-Baptiste Vuillerod and Thibault De Meyer.Free admission. All welcome.Book presentation 1956: the Prix Goncourt is awarded to Racines du ciel, a novel whose hero, Morel, fights against the extermination of elephants in an Africa struggling for independence. Romain Gary described it as the first ecological novel. Ecology enabled him to resolve the unbearable political contradiction in which the post-war West finds itself: the impossibility of believing in man, the impossibility of giving up believing in man. How can we continue to give meaning to the idea of civilization? If we are to maintain the humanist ideal, we need to wage a battle in which man is no longer at the center. Such is the paradox explored here. This literary and philosophical essay reveals the complexity of Romain Gary's thought, his constant irony and humor, his contradictions, his rejection of dogmatism. And its modernity: ahead of his time, the novelist anticipated the controversies driving contemporary ecological thinking, where the human being is only a part of nature, but where nature itself becomes inseparable from history, society and politics. This previously unpublished synthesis of Romain Gary's work is an original analysis of the tension between humanist commitment and ecological cause.. Toutes les activités du Centre Arcadie

As part of its seminar, Centre Arcadie will be pleased to welcome Jeanne Etelain for a session devoted to her book Zones. Terre, sexes et science-fiction, Flammarion, 2025.Jeanne Etelain, PhD from New York University and Université Paris-Nanterre, teaches philosophy and contemporary theory at the École supérieure des Beaux-Arts de Montpellier.After a presentation of the book, Igor Krtolica will be interviewed by Jean-Baptiste Vuillerod and Thibault De Meyer.After a presentation of the book, Jeanne Etelain will be interviewed by Ludovic Dubois, Nathalie Grandjean and Sébastien Laoureux.Free admission. Welcome to all.Book presentation Zone: this ubiquitous term nevertheless remains elusive. In a stunning conceptual investigation at the crossroads of geography, psychoanalysis and science fiction, Jeanne Etelain explores how "zone" has become central to understanding space, in the contemporary context of a crisis in the planet's conditions of habitability. The zone thus emerges as a spatial modality that defies habitual categories, confronting us with space's power to act, whether it's nature, the Earth or the body. All Centre Arcadie activities

Conference organized by Centre Arcadie and the Department of Philosophy as part of the "Philosophie du cinéma" course and the "Cultures et pensées cinématographiques" Specialization Master's degree.Dork Zabunyan is Professor of Film Studies at Université Paris 8 Vincennes-Saint-Denis. His publications include Les Cinémas de Gilles Deleuze (Bayard, 2011), L'Insistance des luttes - Images, soulèvements, contre-révolutions (De l'incidence éditeur, 2016), Foucault va au cinéma (Bayard, 2011) with Patrice Maniglier, Jacques Rancière et le monde des images(Mimesis, 2023).In 2020 he published Fictions of Trump. Puissances des images et exercices du pouvoir(Le point du jour). In this conference, the aim will be to take up this work in the context of Trump's second term.Presentation of the workDonald Trump's body is almost everywhere, outside us, on our screens, caught up in information channels that disseminate still and moving images of him. He is also present within us, more or less floating, in the minds of his detractors and supporters alike. The 45th President of the United States of America is not, however, the book's only subject. Based on his countless audiovisual representations, both before and after his election, the aim here is to explore the function of images in the exercise of power today, the stories they tell and the discourses they condition. Two questions run through this essay: what is this strange love of power, conveyed by images of an authoritarian leader, to which individuals who have no interest in voting for him adhere? What filmic counter-fires, real or imagined, are likely to mobilize the powers of images to evade this power, or even to thwart it? All Centre Arcadie activities

It's official: the University of Namur joins the Réseau d'Échanges et de Liaisons entre Institutions d'Enseignement Supérieur Francophones (RELIEF).

Born on the internet, memes are an integral part of digital culture. These images, often humorous, combine text and visuals to convey a message. At UNamur, Lieven Vandelanotte, professor of English language and linguistics and general linguistics at the Faculty of Philosophy and Letters, has taken an interest in them from a linguistic point of view. In his new book, co-written with Barbara Dancygier of the University of British Columbia, he deciphers how these creations play with words, images, and grammar.
