Parcel deliveries and urban logistics: Changes and challenges in the courier express and parcel sector in Europe — The French case

Abstract: The European Courier, Express and Parcel sector, a strategic and dynamic sector involved in globalization, has undergone significant changes during the past fifteen years. CEP players are “co-evolving” (evolving together), the sector is consolidating itself, strategy and logistics organizations are converging and a new segment dedicated to urban parcel deliveries has emerged. Thanks to a literature review, interviews of the players of the French CEP sector and urban parcel delivery sector, as well as comparisons with other European countries, this article analyzes the sector's changes, its drivers, and provides an accurate picture, based on examples and figures, of an under-studied sector. The article also highlights some future prospects for the new segment such as the segment's consolidation and the rise of cross-border e-commerce.

Biosorption of palladium and platinum by sulfate‐reducing bacteria

Abstract: The biosorption capacities of palladium and platinum were studied in three different species of Desulfovibrio: Desulfovibrio desulfuricans, Desulfovibrio fructosivorans and Desulfovibrio vulgaris. The influence of several parameters such as pH, acidic background and competitor anions on biosorption equilibria and biosorption kinetics were evaluated. Differences were observed between the three strains of Desulfovibrio with respect to the optimum biosorption parameters of both metals, suggesting differences in the metal speciation–dependent sorption mechanisms involved. The most promising Pd and Pt biosorption results were obtained using D desulfuricans with rapid achievement of equilibrium (90% of total sorption was achieved in 5–15 min) and a maximum value of 190 mg g−1 dry biomass and 90 mg g−1 dry biomass for Pd and Pt accumulation respectively, at pH 3.

Revisiting marketization: from interface-markets to market-agencements

Abstract: This article proposes to get rid of the vain opposition between markets as de-socializing forces and markets as civilizing processes by exploring the close relationship between innovation and competition. This suggests abandoning the traditional view of markets as interfaces for the novel conception of market as agencements. Indeed, a thorough examination of the notion of market competition leads to distinguish two ways of describing markets, depending on the role played by product innovations. In interface-markets, innovation strategies aim to reduce competitive pressure, while in market-agencements they are the expression of competition itself. In the former, the definition of market goods is secondary, whereas in the latter it is at the heart of the confrontation between economic agents. The competitive dynamics of market-agencements, which makes the establishment of new bilateral transactions and of product innovation the dominant rule, results in the constant expansion of the market sphere. The marke...

Structural reactivation in plate tectonics controlled by olivine crystal anisotropy

Abstract: Structures formed during ancient tectonic events are commonly reactivated during subsequent tectonism. Numerical models point to mechanical anisotropy arising from the inherited orientation of crystals of the mineral olivine in the lithospheric mantle as the cause of this behaviour.
