Dynamiques géographiques d'émergence et de coconstruction des destinations touristiques gourmandes : de la baie de Naples à la riviera d'Athènes (NADETOURGO): NADETOURGO

Projet de recherche Études touristiquesIn Naples and its bay, beyond the tourist promotion of pizza and the so-called “volcanic taste” (Boutain et Etcheverria, 2026), socio-professional actors in tourism and gastronomy offer culinary tourism experiences that highlight a wide range of agricultural food products as well as culinary and pastry preparations. These offerings take the form of food tours and cooking classes, visits to sites of production and commercialization, and tasting experiences.At the same time, "gourmand tourists"—through their practices, discourses and imaginaries, and through the ways they observe and experience places—directly contribute to these visible dynamics, from Naples to Sorrento and across the slopes of Mount Vesuvius.Adopting a comparative perspective, the case of the Bay of Naples will be placed in relation to that of the Athenian Riviera, where similar dynamics of gastronomization, touristification, heritagization, and eventification can also be observed.À Naples et sa baie, au-delà de la valorisation touristique des pizzas et du goût "volcanique" (Boutain et Etcheverria, 2026), les acteurs socioprofessionnels du tourisme et du gourmand proposent des offres touristiques gourmandes qui valorisent l'ensemble des produits agricoles alimentaires et des préparations culinaires et pâtissières se traduisant par des food tours et des cooking classes, des visites de lieux de production et de commercialisation et des dégustations. Concomitamment, les touristes gourmands, par leurs pratiques, par leurs discours et imaginaires, par leurs regards, participent directement à ces dynamiques visibles de Naples à Sorrento en passant par les pentes du Vésuve. Dans une démarche comparative, l'exemple de la baie de Naples sera mis en perspective avec celui de la riviera d'Athènes, où les dynamiques de gastronomisation, de touristification, de patrimonialisation et d'événementialisation sont également observables

Lipid traits related to body reserves and egg yolks of laying hens at 90 weeks of age: QTL detection and genetic correlations with production traits

International audienceExtending the productive lifespan of laying hens beyond the conventional 70 weeks offers a promising strategy to improve the sustainability and economic efficiency of egg production, while addressing ethical and environmental concerns. However, maintaining high production performance in aging hens requires understanding the genetic basis of lipid metabolism at advanced ages. Lipid metabolism is central to reproductive function in poultry, not only because yolk formation demands substantial lipid investment, but also because lipids provide precursors for steroid hormones and signaling molecules that regulate ovulation and egg production. However, abdominal fat weight (AFW), and yolk percentage (YP), despite being key indicators of lipid dynamics, remain poorly characterized from a genetic perspective at advanced production stages. In this study, genomic architecture of lipid-related traits (AFW, YP) and their genetic parameters with production traits (egg weight, EW; laying rate, LR) were investigated in hens at 90 weeks of age. Liver weight (LW) was included as this organ is the main site of lipid synthesis. These analyses were performed by using an experimental population of up to 7,000 Rhode Island Red hens genotyped with 60k SNP arrays imputed on 600k. Genome-wide association studies (GWAS) were followed by linkage disequilibrium (LD)-based QTL refinement. Considering the hypothesis of causal genetic variants affecting hepatic gene expression, GWAS results were integrated with liver expression quantitative trait loci (eQTL) detected at the same age, enabling the identification of candidate genes whose expression may mediate genetic effects on phenotypes.Heritability estimates for AFW and YP were high (0.48 and 0.51) and comparable to values reported in broilers and layers. Positive genetic correlations of AFW and YP with LR (0.24 and 0.27) suggest that moderate lipid reserves might sustain laying performance at advanced ages, contrasting with negative correlations in younger hens. Conversely, negative correlations of AFW and YP with EW ( 0.16 to 0.54), point to a trade-off between lipid allocation to yolk and abdominal fat reserve and overall egg mass. LW was strongly correlated to YP (0.53) likely reflecting the high contribution of liver-derived lipids to yolk formation, whereas correlations with AFW and LR are only moderate (0.19 and 0.27).GWAS identified several QTLs associated with lipid-related traits. A new locus on chromosome 8 was detected for both AFW and YP, although LD analysis suggested distinct underlying causal variants. Known QTLs for abdominal fat percentage were confirmed on chromosomes 2 and 28. LD-based refinement reduced QTL intervals, improving candidate gene prioritization. For AFW QTL integration with liver eQTLs highlighted several promising regulatory candidate genes, including CYB5A and GDF15 at the chromosome 2 and 28 and for YP the gene OSBPL9 on chromosome 8.These results demonstrate that substantial genetic variability for lipid-related traits persists at advanced ages and are correlated with key production traits. New candidate genes were identified through LD based QTL refinement and hepatic eQTL integration. These findings provide a genomic basis for breeding strategies aimed at improving metabolic efficiency in laying hens during extended production cycles.This project is funded by the European program GEroNIMO N°101000236 and ANR ‘EFFICACE’ program

How to organise a scientific competition to benchmark methods and algorithms in computational biology?

Scientific competitions have driven methodological innovation in artificial intelligence and machine learning, yet remain underutilized in computational biology. This paper provides a comprehensive guide for organizing scientific competitions in bioinformatics, based on our experience with HADACA3, a data challenge focused on deconvolution algorithms for predicting cellular composition in cancer, from multi-omics data. We detail the complete organizational workflow from preparation to execution to postanalysis, offering practical strategies and lessons learned. Beyond advancing multiomics deconvolution methods, HADACA3 demonstrated how expert-guided competitions foster methodological development, scientific exploration, and collaborative networking. By sharing our organizational framework, we aim to democratize scientific competitions as a fundamental methodology for developing and benchmarking computational methods in life sciences.</div

Who are the healthcare professionals involved in interprofessional team meetings in French multidisciplinary primary care centres? A quantitative analysis of eight centres

International audienceBACKGROUND: Interprofessional collaboration is crucial for providing high-quality care to patients with complex conditions in primary care. In France, multidisciplinary primary care centres (MPCC) receive funding if they organise at least 6 interprofessional team meetings (ITM) per year to discuss complex patient situations and collectively define care strategies. It remains unclear how ITM have been implemented in France. This study analyses healthcare professionals’ involvement in ITMs within MPCCs.METHOD: A multicenter retrospective quantitative study in 8 French MPCCs based on the analysis of ITM reports for the period from 2018 to 2019 was conducted. RESULTS: 1733 patients’situations (n = 1733 cases) discussed during ITMs were analysed. The 8 MPCCs were heterogeneous in terms of geographical location, creation date, and size (3 MPCCs with &gt; 20,000 patients followed by more than 60 professionals and 3 MPCCs with &lt; 20 professionals). On average, five healthcare professionals attended each ITM, with huge variations among MPCCs. The nurse-general practitioner (GP) pair was central. At least one GP was present at 89% (n = 1469) and nurses at 38.15% (n = 630) of ITMs. Participation of other professionals was less frequent and varied according to the MPCC. Physiotherapists were present at 7.8% of ITMs, and other healthcare professionals were present at &lt; 6% of ITMs, including pharmacists (3% of ITMs). In some cases, healthcare professionals external to MPCC, particularly those related to mental health, were also involved in ITMs.CONCLUSIONS: Depending on the MPCC, the professionals involved in ITM vary widely, with the nurse-GP pair at the centre. The relative absence of certain professionals needs to be analysed in order to encourage interprofessional working

L'Action Conjointe Didactique pour construire l'art de la danse: Étude du Sacre du printemps de Pina Bausch

The thesis « Joint Didactic Action to build the art of dance. Study of the Rite of Spring of Pina Bausch » is based on the JATD (CDpE, 2019, 2024) which is a theoretical framework for didactic analysis, in continuity with other works conducted in the field of dance (e.g. Messina, 2017, 2019). We used the notions of imitation game and self-milieu to understand the context of dance study. The aim of the research is to help dancers who are looking for a professional training in dance, and to preserve the transmission of choreographies with an exploration of dance movement written coding. The research field involves two institutions of different sizes : ECD, School and Conservatory of Dance in Aosta, Italy, and TMA, Torino Musical Academy in Turin, Italy; in both of them we wanted to study what is transmitted and how what is transmitted is taught. The results were presented with several didactic devices, among others the PFRD, Photographic and Filmic Representations in Dance, which helps keep the material trace of a learning situation. We studied in particular the collective construction of interpretation, breathing, dance gestures and the position in space of a synthesis of choreography.This work has the ambition to create a cooperation between the scientific community of researchers and dance practitioners, to learn to work together in a participatory way.La thèse « L'Action Conjointe Didactique pour construire l'art de la danse. Étude du Sacre du printemps de Pina Bausch » s'appuie sur la TACD (CDpE, 2019, 2024) qui est un cadre théorique d'analyse didactique, en continuité avec d'autres travaux menés dans le champs de la danse (e.g. Messina, 2017, 2019). Nous avons utilisé les notions de jeu d'imitation et de milieu-soi pour comprendre le milieu de l'étude en danse. Le but de la recherche est d'aider les danseurs qui visent à une formation professionnelle et de conserver la transmission des chorégraphies avec une exploration de l'écriture de la danse. Le terrain de recherche voit la coopération de deux institutions de tailles différentes : ECD, École et Conservatoire de Danse à Aosta, Italie qui coopère avec le TMA, Torino Musical Academy à Turin, Italie; ici nous avons voulu étudier ce qui est transmis et comment ce qui est transmis est enseigné. Les résultats ont été présentés avec plusieurs dispositifs didactiques, entre autres les RPFD, Représentations Photographiques et Filmiques en Danse, qui nous aident à conserver la trace matérielle d’une situation d’apprentissage. Nous avons étudié en particulier la construction collective de l'interprétation, de la respiration, des gestes de danse et la position dans l’espace d’une synthèse de la chorégraphie.Cette œuvre a l’ambition de créer une coopération entre la communauté scientifique des chercheurs et les praticiens de la danse, pour apprendre à travailler ensemble de façon participative

Enhancing Spatial Resolution of Sentinel-2 Imagery through Deep Learning and Generative Adversarial Networks: GS-SRGAN

International audienceAbstract. Sentinel-2 satellites provide multi-spectral images with 13 bands at resolutions of 10, 20, and 60 m/pixel, widely used for various applications due to their cost-free access and high revisit frequency. Their open data policy has made them a key resource in remote sensing. Nonetheless, the growing need for high-resolution images has highlighted the significance of super-resolution technology (SR), which improves spatial detail through enhanced sensor precision and density. Deep learning techniques are an effective solution for enhancing Sentinel-2 images through super-resolution, improving low-resolution images by retrieving fine-grained high- frequency details. This results in high-resolution outputs from freely available data. In this research, we propose an enhancement of single-image resolution model derived from a Generative Adversarial Network, commonly abbreviated as GAN. We implemented and trained a model, named GS-SRGAN (Google Sentinel - SRGAN), built on the foundation of the Super-Resolution GAN model (SRGAN), using pairs of Google Earth and Sentinel-2 images for generating super-resolved outputs of the RGB bands from the multispectral Sentinel-2 data using a 4x scaling factor. The results from our GS-SRGAN model surpass those of current best in class models when evaluated using standard metrics such as SSIM (Structural Similarity Index) and PSNR (Peak Signal-to-Noise Ratio), enabling the super-resolved Sentinel-2 imagery for use in studies that demand very high spatial resolution

Les animaux dans le monde romain: Penser l'anthropocentrisme

International audienceWhat is anthropocentrism? How does it differ from speciesism? When did our profoundly unbalanced relationship with animals take shape—and why, and in what ways?This book addresses these questions by returning to the roots of our culture: the Roman world, while also taking into account its Greek heritage. It was during this period that the relationship between humans and animals—and animals’ place within the city—was first theorized. It was also then that animals were “animalized,” just as women and so-called barbarians were.Yet nothing was predetermined. Some voices spoke out in their defense, though they were quickly silenced. Philosophers and theologians instead set out in search of a supposed “property of man,” while jurists enshrined human superiority in law.The book does not shy away from difficult issues, examining the underlying logics that shaped certain practices (veterinary medicine, vivisection, zootechnics, and more). Drawing on our history, as well as insights from cognitive science and anthropology, the author proposes a redefinition of anthropocentrism and presents speciesism as a civilizational choice of which we are the heirs.Qu’est-ce que l’anthropocentrisme ? Qu’est-ce qui le différencie du spécisme ? Quand notre rapport aux animaux, si déséquilibré, s’est-il mis en place ? Pourquoi et selon quelles modalités ? C’est à ces questions que ce livre répond en revenant aux racines de notre culture, le monde romain, non sans tenir compte de l’héritage grec. C’est alors que l’on a théorisé la relation aux animaux et leur place au sein de la cité. Alors aussi les animaux ont été « animalisés », au même titre que l’on a animalisé les femmes et les barbares. Pour autant, rien n’était tracé : des voix ont plaidé leur cause, vite étouffées. Philosophes et théologiens ont préféré partir à la recherche d’un hypothétique « propre de l’homme », tandis que les juristes ont consacré son excellence dans le droit. Le livre n’écarte aucun écueil et interroge les logiques commandant certaines pratiques (médecine vétérinaire, vivisection, zootechnie…). Par le truchement de notre histoire et en se fondant sur l’apport des sciences cognitives et de l’anthropologie, l’auteur propose de redéfinir l’anthropocentrisme et présente le spécisme comme un choix de civilisation dont nous sommes les héritiers

Between stone and ash: Combined method study of Middle Neolithic (4500-3500 BC) cremation and funerary practices in Dolmen A, cairn of Goasseac’h, Brittany, France

International audienceThe Middle Neolithic (4500-3500 BC) in Brittany is predominantly associated with megalithic funerary practices, characterized by collective inhumations within coastal chambered tombs. Moreover, the region is often noted for the absence of preserved bones due to soil acidity. The multi-chambered cairn of Goasseac’h, near Carhaix-Plouguer in Central Brittany, challenges these patterns. One of its nine passage tombs, Dolmen A, presents an exceptional case: a cremation deposit arranged within a structured setting of stones. Given the rarity of cremation during this period, particularly in megalithic tombs, and the distinctive character of the deposit, this discovery provides new insights into Neolithic mortuary customs and raises questions concerning regional burial traditions. The present research integrates anthropological analysis of the cremated remains with spatial analysis of their distribution and associated artefacts, and situates these results within a comparative framework drawing on evidence from Brittany and beyond. The combined analyses provide insights into the treatment of the body during cremation, its biological profile, and the preserved skeletal elements. They also highlight the importance of integrating spatial and osteological analyses, demonstrating the intentional structuring of the deposits and revealing patterned practices in the disposition of the body within a monumental funerary architecture. By placing Dolmen A in the broader context of Middle Neolithic Brittany and the wider European megalithic phenomenon of the 5th millennium BC, this study emphasizes both local variability in burial practices and the broader significance of cremation in collective monuments. The results contribute to a more nuanced understanding of the social, ritual, and symbolic dimensions of Neolithic burial customs
