LA FRAGMENTATION DES RÉSEAUX D'INNOVATION ET LA DYNAMIQUE DES SYSTÈMES TERRITORIAUX DE PRODUCTION ET D'INNOVATION DANS LES SECTEURS TRADITIONNELS
2016
Resumen: Para competir en la globalización, los sistemas territoriales de producción en sectores tradicionales deben convertirse en sistemas territoriales de producción y de innovación. Esto supone urdir redes de innovación más complejas entre actores heterogéneos (empresas, universidades, centros tecnológicos, etc.), lo que genera una tensión política de integración/fragmentación de dichas redes. Para contrastar esta hipótesis se combinan los enfoques evolucionista y del actor-red con el enfoque de la proximidad. La construcción de redes de innovación más amplias exige desarrollar nuevas comunidades de práctica. Este proceso puede generar una dinámica de fragmentación por medio del estable…

Réseaux de distribution de l’énergie et sobriété énergétique des territoires, les apports d’une approche thermodynamique et métabolique des systèmes …
2017
Dans le contexte de transition énergétique et de crise environnementale actuel, les intérêts des approches territoriales et systémiques de l’énergie semblent aujourd’hui admis. Cependant et malgré les nombreuses avancées dans les domaines technologiques, en matière d’urbanisme et d’aménagement ou bien encore en termes d’approches psycho-sociales et comportementales, les courbes de consommations énergétiques peinent à s’infléchir. Fort de ce constat, nous posons l’hypothèse, sur la base d’éléments théoriques empruntés à la thermodynamique et à la biologie, du rôle potentiel que pourraient jouer les réseaux de distribution énergétique, leurs caractéristiques, leur morphologie et leur dynamiqu…
En métal et en céramique. Production, imitation, circulation des oenochoés « rhodiennes » entre la Méditerranée, l’Italie et les communautés no…
2019
At present there is no study taking into account these classe of containers, in different materials and in such a vast geographical area. It is necessary to relate the different productions of these classe of vases, from prototypes to local imitations, in order to understand the role of these products in similar or different contexts. The objective is to approach the contacts between Italy, the Mediterranean and the northern Alpine communities from different aspects:- first of all from the productions and the technical aspects,- then by the identification and in-depth study of the local imitations of these receptacles,- second, by the circulation of imported objects (routes and nature of tr…
Soil microbial networks: what is the relationship with plants?
2020
International audience; Since a long time, the interactions between soil microbes and plant roots are intensively investigated to decipher the role of microorganisms in the growth and the maintenance of plants in a multitude of environmental conditions as climatic stress, agricultural practices or pathogenic/parasitic invasions. Beyond their intimate relationships, the soil microbial communities influence and are influenced by the aboveground vegetation. The interaction/co-occurrence networks are a relatively new look on the soil microbial communities. This look integrates the most comprehensively the community complexity, provides a more complete information on the community and seems to b…
Thèse : L'intégration de l'environnement au droit de l'électricité. Vers le renouvellement d'un service public.
2012
Equality, continuity and adaptability. Foundations of the right of the public utilities, Rolland laws apply vigorously to the public service for electricity, where activities did not change since the advent of the « electricity fairy ». It is always about producing, transporting, distributing and supplying electricity, respecting the general interest. Nevertheless, the legal framework applicable to these activities is under a dramatic transition, stemming from the will of the European Union to create a single market for electricity. These changes incrementally drive to a shift of the public utility, basically socially oriented, to more and more demanding and diversified economic objectives.…
Networks and health care systems
1996
The network concept has been successful in the economic littérature and in the health care economics littérature. However the network concept is not easy to define. In the first part, this paper suggests a framework for network conceptions analysis :first, network can be conceived as a structure of economic organisation (such as infrastructure networks), or as a coordination mode, alternative and different from market or hierarchy coordination. In the second part, this paper analyses recent mutations in the health care system (such as cooperation relationships between several hospitals and private clinics, networks between hospitals and ambulatory medical care...) from the network concept a…
La spécialisation des productions et les spécialistes: Une introduction
2018
With the emergence of manufacturing based economies, specialised productions take on new dimensions during the Neolithic. Production networks progressively develop during the Neolithic and the Metal Ages and can be characterised according to their scale, how they are organised, the status of producers and the intensification of the trade of manufactured goods. This results on the one hand in mass production and on the other in the creation of highly technical objects on demand within a complex economic system of consumption and exchange. This is not seen as a linear progression but as a diversification of productions, products and know-how, the chronological and social contextualisation of …
