    This article examines the sustainability of vertical electronic marketplaces (EMPs) and their value to the organization and productivity of B2B exchanges. What type of value is created? How is it shared in the value chain? Based on the literature, five value dimensions are proposed: information technology (IT), competitive advantage building process, competitive game with suppliers, management of the supplier relationship, economic gains. These dimensions are illustrated by five case studies conducted with the main French retailers in 2005. The article finally discusses the nature of EMPs (private or built in consortium) with transaction cost and resource-based view theoretical backgrounds

    Tectonic evolution of the Rehamna metamorphic dome (Morocco) in the context of the Alleghanian-Variscan orogeny

    Structural and 40Ar/39Ar geochronological investigations of the Rehamna Massif (Meseta, Moroccan Variscan belt) provide new constraints on the tectonic evolution of the Alleghanian-Variscan orogen during the Upper Paleozoic. Three main tectonic events have been recognized: (1) Southward thrusting of an Ordovician sequence over the Proterozoic basement, its Cambrian sedimentary cover, and the overlying Devono-Carboniferous basin. This event caused subhorizontal shearing and prograde Barrovian metamorphism of the buried rocks. (2) Continuous shortening resulting in the development of a synconvergent extrusion of metamorphosed units to form a dome elongated E-W. This was responsible for synconvergent detachment of the Ordovician upper crustal sequence. The timing of these two episodes is constrained to 310–295 Ma by cooling and metamorphic amphibole and mica ages (3) A NW-WNW convergence in a direction orthogonal to the previous one and characterized by the accretion of the Rehamna dome to the continental basement in the east. Based on 40Ar/39Ar cooling ages from a syntectonic granitoid and its host rocks and metamorphic 40Ar/39Ar ages from greenschist facies mylonite, the timing of this event falls between 295 and 280 Ma. The end of the Variscan orogeny in the Moroccan Meseta is constrained by the 40Ar/39Ar cooling age of a posttectonic pluton dated at ~275 Ma. The tectonic events highlighted in Morocco coincide with the late Variscan-Alleghanian tectonic evolution of southern Europe and North America and can be correlated with the global reorganization of plates that accompanied suturing of Pangaea at around 295 Ma.Peer reviewe

    Entre achats et approvisionnements : la valeur perçue des outils des places de marché électroniques

    International audienceL'émergence des places de marché électroniques (PDME) a été souvent associée ? l'idée d'une nouvelle organisation des échanges marchands. L'échec d'un certain nombre de ces PDME interroge théoriciens et praticiens sur la valeur que les utilisateurs perçoivent des principaux outils des PDME. L'étude qualitative réalisée dans les départements achats, approvisionnements et systèmes d'information des principaux acteurs de la grande distribution généraliste française valident empiriquement notre démarche
