Le libre accès à Paris Nanterre

Par Open Access, on entend le libre accès aux résultats de la recherche, diffusés sous forme électronique et en ligne gratuitement. Ce mouvement existe au niveau mondial depuis la fin des années 1990 et s'est concrétisé par des appels adressés à la communauté des chercheurs en faveur du partage des connaissances (appel de Budapest en 2002, appel de Berlin en 2003).

L'université Paris Nanterre favorise l'Open Access par le biais d'un portail HAL, principale archive ouverte en France maintenue par le Centre pour la communication scientifique directe (CCSD), Unité mixte de service sous la tutelle du CNRS, de l'INRIA et de l'Université de Lyon, qui rassemble les publications des chercheurs et chercheuses affilié.e.s à l'établissement. 

D'autres initiatives de Paris Nanterre contribuent au développement du libre Accès, comme la participation des Presses Universitaires de Nanterre au projet OpenEdition Books, la diffusion de plusieurs revues en Open Access sur la plateforme OpenEdition Journals (antérieurement nommée Revues.org) et la création de carnets de recherche sur la plateforme Hypothèses par des chercheur.se.s.


  • [hal-03539353] Residential Care for Children and Youth in France. A Solid System Facing Major Challenges
    23 mars 2022
    The French child protection system builds on a national legislative framework. Since decentralization in 1983, local authorities are in charge of the funding and the follow-up of all measures. However, the State still plays an important role through the Ministry of Justice, with 82% of out-of-home-care measures being court ordered.

  • [hal-03373012] Archaeology of Tibet and the Himalayas: current research and further perspectives (Panel)
    29 avril 2022
    In recent years, the archaeology of the Tibetan plateau, and more particularly of adjacent areas in the Himalayan range, has developed considerably. This rapid development has been possible thanks to new contributions from various fields of archaeology relating to petroglyphs, ceramics, archaeobotanical studies, funerary archaeology, built heritage, etc. These new areas of research are helping to improve our knowledge of the prehistoric and historical human occupation of the Himalayas, which is still poorly understood due, mainly, to the scarcity – or total absence – of written sources. In this panel, we invite archaeologists, and specialists in related fields, to present their ongoing research in an effort to discuss and compare recent findings. Our aim is to engage in subjects such as the chronology and type of the occupation in the region, related material culture, as well as the cultural and material exchange taking place along the Himalayas and Tibetan plateau throughout history. Finally, we also hope to be able to discuss further steps that should be taken in order to develop Tibetan and Himalayan archaeological research.
  • [hal-02499145] Lexicometrical analysis method to support Scoping Review on social dimensions of flow
    23 mars 2022
    Background: Scientific work on the social dimensions of Flow seems to be increasing, but it is currently very fragmented. Moreover, most of them do not know each other. This is why it seems important to identify, collect and make available to the entire scientific community a corpus of academic papers via a freely accessible database. Aims: Our objective is to implement and optimize a generic method for identifying and classifying articles after lexical analysis of abstracts. Methods: We designed and ran a specially crafted search query (a specific combination of keywords and Boolean operators) that come under the notion of social flow, yielding thus a lower number of false-positive results. We were thus successful in identifying about 265 papers from 70 publishers, divided in 39 PhDs and 226 scientific contributions, spanning the last 20 years. Results: The firstTop-Down Hierarchical Clustering of vocabulary of all these abstracts highlight 4 main classes: (1) the different contexts of flow study in groups, (2) theoretical models used for flow study in groups (3) the effects of flow in groups and (4) the human consequences of flow in groups. The correspondence factor analysis allows in particular to identify very clearly the main authors related to each of these 4 classes. Conclusion: The development and optimization of this method will make it possible to strengthen the literature reviews and scoping reviews of researchers and PhD students. It can be a way to federate an international research network on the social dimensions of the optimal experience.
  • [hal-03653751] Corps connectés : figures, fragments, discours
    5 mai 2022
    Nos corps sont désormais inscrits dans les flux de données. Nos nouvelles expériences sensorielles, de déplacement ou d'être ensemble sont amplement modifiées à l'ère de l'hyper-connexion et du Big Data. Mais comment cette nouvelle manière d'envisager nos corps (de notre corps propre au corps social) se traduit-elle ? Quel impact cette condition numérique a-t-elle sur nos vies ? C'est à ces questions que le présent ouvrage s'intéresse, au fil des contributions issues de domaines variés, tels que l'art, le design, la philosophie, la sociologie ou la psychologie, en ouvrant des voies d'analyse aussi hétérogènes que complémentaires. Il s'agit par-là d'ouvrir de nouvelles pistes de réflexion critique, herméneutique et sociétale sur la manière dont nos subjectivités sont affectées par la mise en données de nos corps.

    Cet article analyse le système de vote en ligne Neovote, utilisé pour plusieurs scrutins des primaires présidentielles de 2022 (Primaire Populaire, EELV et LR). Nous montrons que les objectifs de transparence, de vérifiabilité et de sécurité exigés par la CNIL et l'ANSSI ne sont pas atteints. Nous montrons l'incohérence du processus de vérification du vote et les vulnérabilités du système qui permettent la publication d'un faux décompte (arrivé en pratique pendant la Primaire Populaire).
  • [hal-03650294] A Methodology for the Comparison of Human Judgments With Metrics for Coreference Resolution
    10 mai 2022
    We propose a method for investigating the interpretability of metrics used for the coreference resolution task through comparisons with human judgments. We provide a corpus with annotations of different error types and human evaluations of their gravity. Our preliminary analysis shows that metrics considerably overlook several error types and overlook errors in general in comparison to humans. This study is conducted on French texts, but the methodology should be language-independent.
  • [hal-03672129] Refined and simplified modelling of steel-concrete-steel (SCS) composite beams
    21 mai 2022
    This study presents a general simulation methodology to assess both full and partial composite action of steel-concrete-steel (SCS) structures. This refined methodology, using 3D finite elements, is applied to two three-point bending beams in which a different composite action is provided through variation of the number of studs. The comparison to experimental results validates the methodology and the global and local behavior can be reproduced. However, the important calculation cost reduces the use of this numerical strategy to more complex structures. A simplified methodology is proposed with 1D finite elements to represent the connectors. This modelling choice allows to greatly reduce the computational cost. It also imply a reduction of the reproduced phenomena. Particularly, local damage of the concrete core around the dowels is slightly different. Nevertheless, this strategy allows to accurately reproduce the global behavior as well as the failure modes of SCS beams with full and partial composite action.
  • [hal-03672141] Integration of the principle of mesh refinement in the Adaptive Static Condensation (ASC) method
    21 mai 2022
    In order to evaluate the cracking process in large reinforced and pre-stressed concrete structures, a predictive model of concrete damage with refined mesh and a nonlinear law can be required. Because of the computational load, such modelling is not applicable directly on large-scale structures whose characteristic dimensions are over several meters. To overcome this difficulty, a method based on the static condensation, called “ASC” has been proposed. It concentrates the computational effort on the damaged area, which can evolve due to crack propagation or initiation. In order to reach a higher level of representativeness, mesh refinement is integrated into the ASC method in the proposed contribution. The method first uses a coarse initial mesh and refines it only in the domain of interest (DI) to reach a density of mesh adapted to a non-local model (order of the centimeter). This principle of refinement, integrated in the ASC method, is described. It is then applied to a notched bending beam. The use of mesh refinement combined to ASC method allow to keep results similar to a calculation with a fine mesh on the entire structure. However, it also allows a saving in computational time and in memory occupation that increases with the increase in the mesh density of the refined zones.
  • [hal-03673697] Prosody and cognitive accessibility in left-detached topics: lessons from Nigerian Pidgin
    21 mai 2022
    In Nigerian Pidgin, or Naija, a language spoken by some 100 million people in Nigeria, the role of prosody in topic-marking remains an understudied question, particularly with regards to the way in which speakers distinguish between topics which are readily present in the minds of their interlocutors, and less cognitively accessible ones such as those being introduced for the first time. Advances in the field of natural language processing have yielded effective methods for the automatic extraction of stylized prosodic contours from aligned sound files, facilitating the wide-scale study of syntactic units and their melodic properties. Through a combination of manual pragmatic annotation, automatic prosodic stylization, and exploratory statistical analysis, we aim to better understand the prosodic differences between categories of left-detached topics. We hypothesize that there exists a clear relationship between the cognitive accessibility of topics and their associated prosodic contours. More precisely, the most cognitively accessible topics will be characterized by falling F0 contours with low fundamental frequency ranges. Conversely, we consider that less accessible topics will be associated with rising contours and ones covering wide frequency ranges. We also postulate that contours ending in a very high final pitch will be almost exclusive to less accessible topics.
  • [hal-03671606] Intégration du principe de raffinement de maillage dans la méthode de Condensation Statique Adaptative (ASC)
    20 mai 2022
    Afin d'évaluer le phénomène de fissuration dans les grandes structures en béton armé et précontraint, un modèle prédictif de l'endommagement du béton avec un maillage raffiné et une loi de comportement non linéaire peut être requis. En raison du cout de calcul, une telle modélisation est difficilement applicable à l’échelle de la structure complète. Pour résoudre cette difficulté, une méthode basée sur la condensation statique, qui concentre l'effort de calcul sur la zone endommagée, a été proposée. Dans ce travail, la méthode a été développée en y intégrant le principe de raffinement automatique du domaine d'intérêt (DI).
  • [hal-03650637] La Première Guerre aérienne
    12 mai 2022
    L’histoire de la Première Guerre aérienne est restée longtemps écrite par des officiers aviateurs, ayant le plus souvent appartenu au personnel navigant. Excessivement focalisés sur les pilotes, ces hommes tenaient pour évidente la centralité de l’arme aérienne dans la guerre moderne. Restaient aux marges du récit des opérations ceux qui ne tenaient pas les commandes, soit des appareils, soit des escadrilles. Ce choix était aussi dicté par les sources disponibles : ayant concentré les attentions médiatiques et produit l’essentiel des témoignages, chefs et pilotes recueillaient le fruit de leurs efforts, éclipsant dans leur ombre les anonymes sans voix. L’ouverture progressive de perspectives depuis les années 1980 a accompagné l’exhumation de témoignages apportant une épaisseur nouvelle à notre compréhension de la Grande Guerre dans les airs. Plus globale, cette histoire se veut aussi plus inclusive, en intégrant notamment ceux qui furent appelés les « rampants » – personnels non-navigants de l’aéronautique militaire et autres territoriaux, qui ne doivent plus être exclus de « l’épopée des ailes » en tant qu’ils en composent une part essentielle : à l’armistice du 11 novembre 1918, l’Aéronautique aurait compté, selon le SSEA Jacques-Louis Dumesnil, près de 150 000 hommes dont seulement 12 000 pilotes, 4 000 observateurs et bombardiers, 2 000 officiers aérostiers. Sans doute plus exact, le rapport Marin évoque 51 000 combattants et 15 000 non-combattants au 1er octobre 1918, sur un total de plus de 2,6 millions de mobilisés. Ce sont ces hommes et, plus rarement, ces femmes, qui rendaient quotidiennement possibles le vol des appareils, objets de tant de fascination. Le caractère composite de l’arme aérienne pendant la Grande Guerre constitue une originalité de son étude. L’aérostation liée au génie, l’aviation maritime à la Marine, l’aéronautique militaire tiraillée entre artillerie et génie tout en intégrant des effectifs issus de la cavalerie et de l’infanterie : les influences furent nombreuses qui impactèrent l’arme en formation, bientôt dotée de traditions. Dans quelle mesure cette guerre doit-elle être regardée comme la matrice de la nouvelle « armée de l’air » annoncée par certains auteurs dès 1915 ? Proposée pour devenir la 5e arme en 1917, l’aviation connaît une relative institutionnalisation dans cette épreuve du feu qu’est la Grande Guerre où l’armement, le recrutement, les stratégies évoluent et esquissent les contours de doctrines. En 1918, à peine 3% des effectifs sous les drapeaux servaient effectivement dans l’aéronautique militaire. C’est certes peu en comparaison du reste des mobilisés, mais beaucoup à l’échelle de l’arme qui n’avait jamais tant compté. Ses appareils volent 2 fois plus vite, 3 fois plus loin et 5 fois plus haut au moyen de moteurs près de 4 fois plus puissants qu’à l’été 1914. Ses membres ont appris un « métier » qui évolue constamment avec la guerre. Ils participent à acculturer une partie significative de la population française à l’arme aérienne et à ses possibilités, de sorte que personne ne peut plus ignorer la réalité militaire de l’aéronautique en sortie de guerre.

  • [hal-03665159] La percussion lancée dans l’Aurignacien ancien du Bergeracois : quelques exemples issus des sites de Barbas III, Vieux Coutets, Les Garris et Cantalouette II (Dordogne, France)
    13 mai 2022
    In order to illustrate the launched percussion activities during the Early Aurignacian, we have selected four of the 15 sites appertaining to this technocomplex in the Bergerac region, in Southwestern France. The occupation of this territory, very rich in good quality flint nodules, some of which display imposing morphologies and dimensions, shows a certain functional complementarity between the different Aurignacian occupations, from the specialized occupation to the habitat site. In addition to technological particularities, such as the production of large blades (greater than 20 cm) or the coexistence of curved and straight lamellar production systems, this Early Aurignacian also illustrates some remarkable symbolic behavior expressed in body ornaments and artistic depictions. In these sites, the tools used in launched percussion, although always present, represent a marginal tool category, showing also a great diversity of functions. Three major classes of tools have been recognized: blunt impact tools, sharp impact tools, and linear blunt tools (an intermediate form between the other two). Each of these groups is oriented towards complementary uses within the range of activities made in these occupations. The blunt impact tools comprise a wide range of hammer-stones that take part in different phases of knapping activities, such as the opening of new blocks or the reconfiguration of cores, according to their physical and mechanical properties. Also, the traces left by these hammers are visible on other artifacts left on the sites, such as notches of carinated end-­scrapers. The sharp impact tools comprises a diversified range of cutting tools made on different blanks (preforms, cortical flakes, blades) obtained in laminar production. These tools present a particular morpho-functional structure of active or prehensive parts, natural or made, that improves an ergonomy essentially based on mass. This ergonomy, combined with the kinetics of launched percussion, gives these tools a great efficiency in chopping medium and hard organic materials. Finally, the linear blunt tools is represented by a single tool with blunt linear active zones, formed by open dihedrals with angles between 85 and 115°. The kind of activity made with this tool seems different, it bears traces of recurrent impacts similar to those present on tools used for grinding, pounding or crushing, suggesting also the presence of an anvil. These tools are very often associated with the transformation of plants. This panoply of diversified percussive tools complements the activities perceived on the other cutting and scrapping tools. This, again, illustrates the variety of activities made at this sites, basically the acquisition and transformation of organic perishable materials (of plant and animal origins), contributing to demonstrate that the Early Aurignacian occupations of the Bergeracois are much more complex thansimple flint workshops.
  • [halshs-03663686] Trace d'origine anthropique sur os: épistémologie et préhistoire. Le cas d'un ossement humain artéfactualisé du Mas d'Azil (Ariège).
    20 mai 2022
    La réflexion sur la manière d’analyser l’artéfact archéologique en Préhistoire, menant le préhistorien à devoir formuler une méthodologie propre au matériel étudié, nous a mené à mettre en place un couplage interdisciplinaire à l’interface entre anthropologie physique et technologie osseuse dans le cadre de l’étude de l’humérus droit humain du Mas d’Azil. Grâce à une analyse réalisée en double front, à la fois comme objet biologique et comme objet technique, d’après les trois types de stigmates relevés (traces de découpe, dépôt coloré rougeâtre, lustre), nous avons pu dégager une chaîne opératoire mortuaire atypique. D’abord décarnisé et démembré, puis coloré à l’aide d’un badigeon liquide rougeâtre et enfin probablement enveloppé dans un contenant semi-souple et transporté, l’humérus droit du Mas d’Azil révèle l’artéfactualisation dont il fut l’objet et porte la mémoire de par ses stigmates. La biographie de l’artéfact a ainsi offert la possibilité d’appréhender une pratique cultuelle au caractère d’exception pour la période et la zone considérées. Si notre entreprise se fonde sur une réflexion épistémologique sur la manière d’analyser l’os anciennement anthropisé, elle a démontré l’importance de ce type d’étude dans la compréhension des groupes préhistoriques en France. L’analyse de l’humérus droit humain incisé, ocré et lustré du Mas d’Azil offre un exemple fondamental des pratiques mortuaires à la Préhistoire et permet de mettre en avant l’inclusion du traitement du cadavre en tant que processus technique ayant transformé le reste biologique en artéfact.

    Contexte: L’Expérience Autotélique (Flow) est un état psychologique humain fortement corrélé à l’auto-efficacité, la motivation, l’engagement et la persistance, notamment dans des contextes de formation à distance, et/ou en ligne. Ainsi, l’implémentation dans un tableau de bord d’indicateurs en permettant la détection rapide et simple, notamment via le modèle du flow en éducation (EduFlow) serait d’une très grande utilité pour renforcer la réussite des étudiants. Méthode: Nous associons les résultats de deux instruments psychométriques (n ~ 1000) à des techniques d’apprentissage automatique (Machine Learning) pour calculer un modèle prédictif de présence et absence de l’Expérience Autotélique à travers ses composantes : l’absorption cognitive, transformation du temps, perte de la conscience de soi, et l’expérience autotélique. Résultats: Les résultats de cette recherche fournissent un instrument de détection de l’Expérience Autotélique fiable (précision > 75%) et relativement simple à incorporer dans des Tableaux de Bord existants. Discussion: Il est nécessaire d’améliorer la fiabilité de l’échantillon de données d’entrée et d’en augmenter le nombre d’effectifs.

  • [hal-03656727] Spatial social networks for the humanities: A visualization and analytical model
    10 mai 2022
    In this article, we propose a model to identify the spatial and structural characteristics of a specific type of social networks: the family. The model is the third (Giordano & Cole, 2018, 2019)-and the most fully realized-in a series we have developed in the last four years as part of our work on the topic of platial GIS, or the GIS of place. The model is both a visualization of a spatial social network and an analytical tool and it is also replicable and adaptable to projects in which the dataset Dunder study includes temporal and spatial information as well as demographic data. The case study we discuss in this article concerns the immediate post-Holocaust period in Budapest: in the summer of 1945, the Hungarian Section of the World Jewish Congress-American Joint Distribution Committee and the Jewish Agency for Palestine Statistical and Search Department (World Jewish Congress in brief) commissioned a door-to-door survey to determine where Jewish survivors were living in the city, which at the time was the largest single urban concentration of Jews in postwar Europe.

  • [hal-03510952] Simulation of large dimensional reinforced and prestressed concrete structures using a new adaptive static condensation method including automatic mesh partitioning
    6 janvier 2022
    In order to evaluate the cracking process in large reinforced and pre-stressed concrete structures, a predictive simulation of concrete damage with a refined mesh and a nonlinear law is required. Because of the computational load, such modelling is not applicable directly on large-scale structures whose characteristic dimensions are over several tens of meters. To deal with this type of structure, an adaptive static condensation method (ASC), which concentrates the computational effort on the damaged area (domain of interest) only, is proposed. The ASC method is first presented. A particular attention is paid to the needed developments to extend its domain of application up to prestressed concrete structures. The method is then applied to a three point bending prestressed beam and validated by comparison to a classical finite element damage computation. The numerical efficiency of the proposed approach is evaluated with, on this application, a time saving factor of about 15. An automatic mesh partitioning method is then implemented to make the method even more efficient. Based on physical considerations, it takes into account the expected shape and the evolution of the damaged regions during the loading. It is applied to three test cases with different geometries and loading to discuss the calibration process through a sensitivity analysis. A unique set of parameters is finally proposed and the efficiency of the method is demonstrated. As a conclusion; a complete automatic method is made available for the simulation of large scale reinforced and prestressed concrete structures

The originality lies in the local modification of the mesh and in the treatment of the crossing points of the trajectories.
  • [halshs-03552741] Coupling spatial modeling with expert opinion approaches to restore multispecies connectivity of major transportation infrastructure
    29 avril 2022
    It is widely recognized that major transportation infrastructures such as highways degrade habitats, increase the risk of collision mortality, and cause alterations in landscape connectivity by reducing connections between habitats due to the barrier effect. Wildlife crossings (underpasses and overpasses) have therefore become standard practice to reduce these effects on wildlife. Most studies aim to identify relevant locations for the creation of new wildlife crossings, but it is very rare for results based on modeling tools or animal movement records, for example, to be confronted with expert opinion and knowledge. Our paper provides a methodological framework combining modeling tools and field expertise from a multi-scale perspective. We used complementary connectivity metrics from graph theory to accurately quantify and spatialize the most relevant areas to improve habitat connectivity with multispecies conservation goals. The connectivity analysis was coupled with field expertise to take into account the local context, and technical and land feasibility. We prioritized existing road structures for improvement, found the best locations for new wildlife crossings, and made specific, costed technical recommendations. We empirically tested this approach on a large highway network in Northern France. This allowed us to define work principles to improve 109 existing road structures and to create underpasses or overpasses on 15 road sections. This innovative study for operational purposes has been a useful tool to assist the decision-making process of land-use planners who wish to improve wildlife crossings on major transportation infrastructures.

    21 mai 2022
    Purpose: The purpose of this study was to assess whether the retail food environment, measured by multiple indicators around the home and in activity space, was associated with the nutritional quality of food purchases. Methods: This cross-sectional study included 462 households from a quota sampling survey conducted in the south of France (Montpellier Metropolitan Area). The revised Healthy Purchase Index was implemented in order to assess the nutritional quality of food purchases. Food environment indicators (presence, number, relative density and proximity of food outlets) were calculated around the home and in activity space using a geographical information system. Six different types of food outlets were studied: supermarkets, markets, greengrocers, bakeries, other specialized food stores (butcher’s, fishmonger’s and dairy stores) and small grocery stores. Associations between food environment and the nutritional quality of food purchases were assessed using multilevel models, and geographically weighted regressions to account for spatial non-stationarity. Models were adjusted for households’ socioeconomic and demographic characteristics. Results: The nutritional quality of food purchases was positively associated with the number of greengrocers around the home (1 vs. 0: β = 0.25, 95%CI = [0.01, 0.49]; >1 vs. 0: β = 0.25, 95%CI = [0.00, 0.50]), but negatively associated with the number of markets around the home (1 vs. 0: β = -0.20, 95%CI = [-0.40, 0.00]; >1 vs. 0: β = -0.37, 95%CI = [-0.69, -0.06]). These associations varied across space in the area studied. For lower income households, the number of greengrocers in activity space was positively associated with the nutritional quality of food purchases (1 vs. 0: β = 0.70, 95%CI = [0.12, 1.3]; >1 vs. 0: β = 0.67, 95%CI = [0.22, 1.1]). Conclusions: Greengrocers might be an effective type of food store for promoting healthier dietary behaviors. Further studies, particularly interventional studies, are needed to confirm these results in order to guide public health policies in actions designed to improve the food environment.
