Actes audiovisuels de colloques: perspectives de diffusion scientifique
No full textInternational audienceThis article looks at scientific publications and specifically scientific videos. The aim is for scientific audiovisual publications to have a value comparable to printable publications. The introduction questions the scientific recognition of publications, before turning to the characteristics of printable scientific publications, which highlights the characteristics of scientific audiovisual publications. From these generalities, this article specifies a theoretical framework and a methodology for recording/ broadcasting traces of symposia as a modality of scientific publication. The methodology outlines how these principles were applied to the recording of the 2nd and 3rd Visual and Multimodal Methods conferences held at the Universityof La Laguna. The results cover the process used to capture and publish the 3rd symposium on Visual Modi Canal-U channel.Este artículo se ocupa de las publicaciones científicas y, más concretamente, de los videogramas científicos.

A 7000-year record of human influence on Global River Deltas: Geomorphology, stratigraphy, the Anthropocene overprint and future
No full textInternational audienceWith the inception of most of the world’s deltas about 8000 years ago, deltaic floodplains started offering, about a thousand years later, arable land, water and ecosystem services for early human settlements. We identify delta geomorphic changes and proxies and geoarchaeological markers of the human presence on deltas and in their stratigraphy over the last 7000 years, and from ancient maps. We analyse the human-delta relationship in four phases: Neolithic, Metal Ages, Common Era, and Anthropocene, marking increasing human adaptation to changing delta geomorphology modulated by fluctuations in relative sea level and fluvial sediment supply. These adaptations fostered the emergence of urbanization and served as a catalyst for technological innovation and human modification of deltas. The sparse Neolithic human presence in delta stratigraphy gradually expanded to become pervasive in the contemporary Anthropocene, reflecting the twin effects of global population growth and increasingly favourable conditions for humans. We explore the links between early deltaic and non-deltaic communities and gauge the impact of humans on sediment supply from river catchments, and its consequences, notably in terms of frequent delta avulsions, expansion or vulnerability, and explore its inextricable links with climate variation. The Anthropocene is witnessing a profoundly transformed, globally distributed, human-managed delta landscape dominated by important urbanization, reduction in sediment supply, increasing intentional but also unintentional delta modifications, and vulnerability to sea-level rise compounded by exacerbated subsidence. Understanding the human-delta relationship over the past 7000 years contributes to fostering stronger links between geoscience and cultural heritage, to better delta management and sustainability, including an upstream river-basin scale perspective, and to better anticipation of delta futures, notably under the threat of sea-level rise
Optimal Craig–Bampton mode selection for nonlinear flexible multibody analysis
No full textInternational audiencePhysics-based simulations are now widely employed in mechanical engineering. Flexible Multibody dynamic Simulations (FMBSs) have proven to be effective in representing the behavior of complex structures with local damping and stiffness nonlinearities. However, due to the broad range of component flexibilities as well as contact behavior between structural elements, time integration analyses can result in high computational burden. The challenge addressed in this article concerns the implementation of an efficient model reduction procedure in order to provide an acceptable tradeoff between calculation time and loss of accuracy in the prediction of system responses and dynamic loads. In most FMBS commercial software, the behavior of linear elastodynamic components is taken into account via imported Craig–Bampton superelements. In this context, dynamic mode selection techniques have been shown to provide a better order reduction than the standard low-frequency truncation. This article provides a review of dynamic mode selection methods that can be found in the literature, followed by a comparison based on simulations of an aircraft engine stator integrated in the full industrial engine model and tested on a speed ramp-up with unbalance
L'inclusion scolaire des élèves en situation de handicap au prisme de la pédagogie différenciée en classe ordinaire
No full textThis research paper thesis deals with the educational inclusion of students with disabilities through the lens of differentiated pedagogy in ordinary classroom. Today, the inclusion of students with disabilities in ordinary class is one of the priorities of national education and we take a look at current teaching practices of teachers in France in view of legislative developments. In this thesis, we study the extent to which differentiated pedagogy is implemented among students with disabilities to facilitate their inclusion in ordinary classes. In order to conduct this research, we determined a methodological approach based on the qualitative method and the use of semi-directed interview with the objective of responding to different hypotheses. The analysis of results highlights the impact of pedagogical differentiation, focusing on content, learning environments, productions and learning processes, about access to school inclusion in ordinary class for students with disabilities.Ce mémoire de recherche traite de l’inclusion scolaire des élèves en situation de handicap au prisme de la pédagogie différenciée en classe ordinaire. Aujourd’hui, l’inclusion des élèves en situation de handicap en classe ordinaire fait partie des priorités de l’éducation nationale et nous portons un regard sur les pratiques pédagogiques actuelles des enseignants en France au regard de l’évolution législative. Nous étudions dans ce mémoire dans quelle mesure la pédagogie différenciée est mise en oeuvre auprès d’élèves en situation de handicap pour faciliter leur inclusion en classe ordinaire. Afin de conduire cette recherche, nous avons déterminé une approche méthodologique basée sur la méthode qualitative et l’utilisation de l’entretien semi-directif dont l’objectif est de répondre à différentes hypothèses. L’analyse des résultats des deux entretiens menés met en lumière l’impact de la différenciation pédagogique selon quatre axes de différenciation : les contenus, les environnements d’apprentissage, les productions et les processus d’apprentissage, facilitant l’accès à l’inclusion scolaire en classe ordinaire des élèves en situation de handicap
Fancy Some Chips for Your TeaStore? Modeling the Control of an Adaptable Discrete System
No full textInternational audienceWhen designing new web applications, developers must cope with different kinds of constraints relative to the resources they rely on: software, hardware, network, online micro-services, or any combination of the mentioned entities. Together, these entities form a complex system of communicating interdependent processes, physical or logical. It is very desirable that such system ensures its robustness to provide a good quality of service. In this paper we introduce Chips, a language that aims at facilitating the design of models made of various entwined components. It allows the description of applications in the form of functional blocks. Chips mixes notions from control theory and general purpose programming languages to generate robust component-based models. This document presents how to use Chips to systematically design, model and analyse a complex system project, using a variation of the Adaptable TeaStore application as running example
Procrastination scolaire : analyse des causes, évaluation de la méthode d’accompagnement des élèves et de la technique des rappels et sur leur efficacité quant à la réduction de la procrastination
No full textThis dissertation tackles the different causes of academic procrastination and the levers that can be implemented to overcome it. Indeed, procrastination in school is often linked to lower grades. Therefore, it is important to determine the causes and solutions which can be used to support students in their learning. First of all, an assessment of the causes of procrastination has been made through the lens of psychology, psychoanalysis, sociology and an educational approach of procrastination. This documentary journey has allowed to find some of the causes of academic procrastination - for instance low self-esteem or poor time management - and the variety of solutions which can be put into practice to resolve it. These two techniques, « recap » and « student assistance » through review sessions, are the ones which have been used for trial. First, these methods were applied. Secondly, the student grades were gathered. And for the « recap » technique, their learning frequency was collected. Finally, these results were processed in order to check if those methods affected school grades positively and if they were linked to learning frequency. According to the results, one can observe that implementing learning sessions for students in middle school has had zero effect on increasing their marks. Some of the students seem to feel comfortable in postponing their work as they don’t want to work more because of their boredom and lack of interest in their education. On the other hand, the « recap » method seems to have given better results for high school students. Indeed, learning their lessons more frequently has led to a relative increase in their school grades.Ce mémoire s’intéresse aux différentes causes de la procrastination académique et des leviers pouvant être mis en place pour y remédier. En effet la procrastination en milieu scolaire et souvent associée à de moins bons résultats. Il est donc important d’identifier les causes ainsi que les solutions pouvant être mises en place afin de soutenir au mieux les élèves durant leurs apprentissages. Dans un premier temps, il a été fait ici un état de l’art sur les causes de la procrastination à travers les prismes de la psychologie, psychanalyse, sociologie et approche éducative de la procrastination. Ce parcours documentaire nous a permis d’identifier certaines causes de la procrastination académique – comme, entre autres, une faible estime de soi ou une mauvaise gestion du temps - et les diverses solutions pouvant être appliquées afin d’y remédier. Deux techniques, celle dite « des rappels », ainsi que celle dite « de l’accompagnement des élèves » par des séances de révisions, sont celles pour lesquelles une expérimentation a été réalisée. Une fois l’application de ces méthodes mise en place, le recueil des notes chiffrées des élèves et – pour la méthode des rappels – leur fréquence de révision, ont été recueillis. Ces résultats ont ensuite été traités afin de vérifier si ces méthodes impactaient positivement les résultats scolaires et -ou- étaient en lien avec les fréquences de révision. En vue des résultats nous pouvons constater que la pratique de séances de révision avec les élèves de collège n’a pas eu d’impact sur l’augmentation de leurs résultats scolaires. Certains de ces élèves semblent se complaire dans la remise à plus tard, ne souhaitant pas travailler davantage car désabusés et désintéressés de leur scolarité. Pour ce qui est de la méthode des rappels, celle-ci semble avoir plutôt bien fonctionné pour les élèves de lycée ; en effet, le fait de réviser plus fréquemment a induit une augmentation – au moins relative – de leurs résultats scolaires

Les déterminants de l’investissement dans des fonds verts pour les investisseurs individuels
No full textIn the face of growing environmental challenges, finance represents a key driver of sustainable change. In this context, individual investors have the opportunity to contribute by financing pro-environmental projects. Aware of this potential, the European Commission brings to light the importance of individual investors in developing the sustainable market and establishing green investing as a mainstream solution for environmental protection. However, this potential remains untapped, as individual engagement in the green investing market is still limited. The aim of this thesis is to explore how to unlock the potential of individual investors by investigating the motivations driving their decisions to invest in green funds, and whether these motivations also impact the amounts allocated to such investments. Grounded in the Multi-Attribute Utility Theory (MAUT), which extends Markowitz’s (1952) classical mean-variance model by incorporating the greenness of investments as an additional decision-making criterion, this thesis explores the influence of both financial and non-financial drivers on green investment behavior. To empirically investigate these factors, data was collected through an original survey distributed by Panelabs, the leading provider of research data in France. The survey targeted a sample of 2,215 French individual investors. Our findings reveal that both pecuniary and non-pecuniary motivations significantly impact green investment behavior. Among the tested drivers, four stand out as the most influential: the perceived financial return of green funds relative to their conventional counterparts, social circle expectations, a green political orientation, and a positive attitude toward green investments. A major contribution of this research is the creation of a comprehensive model of the factors influencing green investment, which combines three theoretical approaches and empirical elements drawn from the literature on Socially Responsible Investment (SRI). By implementing this model on French individual investors, the thesis advances the understanding of actual green investment behavior. From a managerial standpoint, this thesis offers sustainable financial actors useful insights into identifying possible green investors and creating successful strategies to encourage environmentally friendly investments.Face aux défis environnementaux croissants, la finance représente un levier clé du changement durable. Dans ce cadre, les investisseurs individuels disposent de l’opportunité de contribuer en finançant des projets pro-environnementaux. Consciente de ce potentiel, la Commission Européenne met en avant l’importance des investisseurs individuels dans le développement du marché durable et dans l’établissement de l’investissement vert comme une solution courante pour la protection de l’environnement. Pourtant, ce potentiel reste inexploité, en raison d’un faible taux d’engagement individuel dans les investissements verts. L’objectif de cette thèse est d’explorer comment libérer le potentiel des investisseurs individuels en étudiant les motivations qui sous-tendent leurs décisions d’investir dans des fonds verts, ainsi que l’impact de ces motivations sur les montants alloués à de tels investissements. S’appuyant sur la théorie de l’utilité multi-attributs (MAUT), qui enrichit le modèle classique de moyenne-variance de Markowitz (1952) en intégrant la dimension environnementale des investissements comme critère supplémentaire dans la prise de décision, cette thèse analyse l’influence des facteurs financiers et non financiers sur le comportement d’investissement vert. Pour ce faire, les données ont été recueillies à l’aide d’un questionnaire original distribué par Panelabs, le principal fournisseur de données quantitatives pour les chercheurs en France. Ce questionnaire a ciblé un échantillon de 2,215 investisseurs individuels français.Nos résultats montrent que les motivations pécuniaires tant que non pécuniaires influencent de manière significative le comportement d’investissement vert. Parmi les facteurs étudiées, quatre ressortent comme les plus influents : la perception du rendement financier des fonds verts par rapport à celui des fonds conventionnels, les attentes du cercle social, l’orientation politique verte ainsi qu’une attitude positive envers les investissements verts. Cette recherche a pour contribution majeure la création d’un modèle intégratif des facteurs influençant l'investissement vert, qui combine trois approches théoriques et des composantes empiriques issues de la littérature sur l'Investissement Socialement Responsable (ISR). En mettant en œuvre ce modèle pour des investisseurs individuels français, la thèse améliore la connaissance du comportement d'investissement vert effectif. D’un point de vue managérial, cette thèse fournit aux acteurs financiers durables des pistes pour repérer les investisseurs verts potentiels et concevoir des stratégies en vue de favoriser les investissements environnementaux
An Introductory Approach to the Reception of Charles Bukowski’s Performance Poetry, Reperformed Online
No full textInternational audienceCharles Bukowski meant his poetry to be performed. In the 1960s and 1970s his editor, Lawrence Ferlinghetti, among others, organised public poetry readings where Bukowski was the star. Some recorded his performances, which were later found on compact disks or in documentaries released after his death. Some shows were retold in books by his friends or scholars. His voice was deep and melancholic, adding value to his words. The purpose of this article is to discuss the transfer of Bukowski’s poetry performance skills online. Indeed, readers of Bukowski have invested time and effort to “remediate” (Bolter and Grusin 1999) Bukowski’s poetry, using a new medium to create new ways of performing poetry. Using the example of the poem “The Crunch” selected from a corpus of 30 YouTube videos created by amateurs and a selection of video excerpts, and studying the use of image and audio within these videos, I will discuss the remediation of Bukowski’s poetry in a new medium and how this can affect its reception. The goal of this article is to decide which methodologies and tools could be practical in such a study. The voice is not the only tool that is used when performing online, sound and images are also taken into account. This article is introductory and reflects on the reception this new form of poetry performance, as we can either read, listen to, or watch poetry independently, or all of the above, using the ImageJ processor and Praat to study the videoed poems
