L'auto-sélection des femmes dans les carrières artistiques
2012
Nombreuses sont les données statistiques et les recherches qui ont démontré les obstacles rencontrés par les femmes pour s'affirmer sur le marché de l'emploi artistique. Si ces inégalités de genre dans la réalisation des parcours professionnels artistiques sont aujourd'hui actées, peu de recherches se sont intéressées à la mise en place de ces différenciations dès le début de carrière. La recherche conduite sur l'insertion des diplômées du DNSEP en Ecole d'art met notamment en avant des processus d'auto-sélection de la part des femmes artistes, aux premiers temps de leur insertion, qui réduisent la visibilité de leurs compétences professionnelles sur le marché du travail.
L'école, l'état des savoirs
2000
L'école constitue aujourd'hui plus que jamais un des enjeux majeurs de l'action politique et occupe une place importante dans les débats publics. L'efficacité du système scolaire, sa capacité d'intégration, son organisation, l'orientation des contenus d'enseignement, la formation et les pratiques pédagogiques des enseignants font l'objet de multiples critiques et propositions émanant de tous les bords. Cet ouvrage collectif, accessible aux non-spécialistes, a pour ambition d'éclairer ces débats. Rassemblant près de cinquante contributions, il présente un état des savoirs le plus complet possible sur la situation de l'école française.On y trouvera une analyse des différents réseaux, niveaux …
Comprehensive valorisation of technically relevant organosolv lignins via anodic oxidation
2021
Lignin represents the largest renewable feedstock of aromatic moieties in nature. However, its valorisation towards organic chemicals poses a challenging task. We herein report the selective electrochemical depolymerisation of several technically relevant organosolv lignins to aromatic fine chemicals with a simple two-electrode arrangement using caustic soda as electrolyte. Vanillin, syringaldehyde, the corresponding ketones and guaiacol were obtained with a combined maximum of 7.8 wt% isolated yield. Deeper insight in the process was provided by FT-IR, HSQC NMR and 31P NMR analyses of the lignins.
La costruzione del paesaggio ibleo: reti deboli, segni forti
2017
The contribution deals with the theme of the dry stone walls’ landscape which characterizes the rural “Koinè” of the Hyblean plateau in South-Eastern Sicily. The essay analyses the main political-economic, social-territorial, constructive and typological features which make the dry walls network the landmark of the Ragusa province. Because of the modification of the economic-cultural context that produced it, the loss of knowledge of the construction techniques and the lack of public resources, the definition of an axiology of the contemporary landscape as premise for the establishment of adequate terms of value for the safeguard of this heritage is required.

TOWARDS AN ADVANCED CONSERVATION STRATEGY: A STRUCTURED DATABASE for SHARING 3D DOCUMENTATION between EXPERT USERS
2019
Abstract. Nowadays, the researchers in Cultural Heritage fields investigate more and more about advanced conservation strategies that comprehend the possibility to share and use 3D models and structured information related to them. One of the modern method adopted to achieve this goal is to use structured web-platform. These are online systems that can handle data, created to contain and support precise information. They simultaneously respond to the need for a common ground for different expert users and of a unique tool where to store several kinds of data, coming from heterogeneous sources. The article aims to show how it is possible to build a valid tool for the conservation and monitor…
Environmental assessment of energy valorisation of residual agrofood industry biomass in Sicily: a life cycle approach
2020
Anaerobic digestion (AD) uses biomass to produce biogas to generate heat and/or electricity. Several studies have reported that the adoption of AD may not necessarily lead to sustainable practices. For example, energy crops may cause significant impact due to the requirement of intensive agricultural practices. Then, residual biomasses are starting to be considered as alternative biomass for energy valorisation trough AD. In this context, this study assesses the potential environmental impacts related to the energy valorisation of agro-food industry waste though the Life Cycle Assessment methodology (ISO 14040). The system examined consists of a real anaerobic digester coupled with a combin…
Les stratégies de développement touristique des territoires de l’espace Rhin-Rhône : une nouvelle cohérence impulsée par le TGV
2012
International audience; The eastern branch of the Rhine-Rhône highspeed line was opened on 11th December 2011. It offers new connections in France and in Europe. Relationships between transport and economic development has often been studied in the literature. This article is an analysis of the relationship between transport, tourism and territory based on the promotion campaigns and the tourism development strategies in the territories newly connected by the high-speed line. Local projects have been catalogued and regional players have been interviewed in order to show how this new infrastructure can be appropriated to enhance the territorial reputation. An analysis of the current cooperat…
ION EXCHANGE MEMBRANE CRYSTALLIZER FOR MAGNESIUM RECOVERY FROM SEAWATER AND INDUSTRIAL BRINE
2020
The treatment and valorisation of waste brines deriving from industrial processes raised in the last years a strong interest in order to promote the whole process sustainability both in terms of minimisation of environmental impacts and raw materials recovery within a circular economy approach. With this respect, magnesium recovery from brines can be an interesting and practical example. In this work, a novel ion exchange membrane crystallizer (CrIEM1) is presented. In a CrIEM reactor, the presence of an Anion Exchange Membrane, separating a brine and an alkaline solutions, allows the passage of hydroxyl ions from the alkaline to the brine compartment, where crystallization of magnesium hyd…
Étude des traces de pas de vertébrés du Permien et du Trias d'Ardèche. Enjeux et perspectives.
2022
Le département de l'Ardèche estremarquable car il offre un accès privilégié auxroches sédimentaires permiennes et triasiques danslesquelles abondent les traces de vertébrés fossiles.Une vingtaine de localités et plus de 1500empreintes de pas ont déjà été recensées le longd'une succession sédimentaire affleurant entrePrivas et Les Vans. Ce patrimoine ichnologique,reconnu internationalement, documente le passagede grands groupes de reptiles en terres ardéchoises,incluant essentiellement des représentants basauxde la lignée des crocodiles (pseudosuchiens) et de lalignée des oiseaux (dinosauriformes et dinosaures),ainsi que quelques membres de la lignée des lézards/serpents (lépidosauromorphes)…
