Pre- and syn-eruptive geochemistry of volcanic gases from Soufriere Hills of Montserrat, West Indies
1998
International audience; Soufriere Hills fumaroles contained magmaderived volatiles before and during the eruption initiated in 1995 but also preserved a typical and quite steady hydrothermal coinposition. Chemical changes due to increased boiling and a greater input of oxidizing magmatic gas occurred only at Galway's Soufriere, the most active fumarolic field. Hydrothermal buffering of the fumaroles has been favoured by their remote location (!-2 km) froin the eruptive vents and by a preferential degassing of the uprising magma through intrusive conduits under the crater. High temperature (720øC) gas collected froin the extruding lava dome in Feb. 1996 was chemically and isotopically repres…
La restauration des grands migrateurs rhodaniens et méditerranéens : contribution des sciences biologiques et sociales
2001
In order to warrant the sustainability of migratory fish in the Rhone and Mediterranean area, two policies have been developed. The first one, concerning shads, has already made possible to pass the first three locks and several weirs on the tributaries. Symmetrically, a concerted restoration plan has been elaborated for the restoration of eels populations. Its main objective consists of making resettlement of their habitat, fully performing their ecologically regulating role, and satisfying social and economic requirements. The role of scientists appears to be major, for diagnosing and assessing the ecological justification of the actions, their technical viability (esp. of stocking), and …

«Cité ou oublié» : les supports de la notoriété des professeurs en sciences de gestion vus à travers Google Scholar
2011
Standards for the evaluation of management scholars lead more and more to exclude forms of scientific production other than the articles published in international scientific journals. The aim of this paper is to test the validity of these norms by analyzing the production of all university professors in management science, based on the «influen- tial» publications in Google Scholar. The articles published in internation- al journals represent only 35 % of in- fluential publications and collect only 40.2 % of citations. Books still repre- sent a very important part and the in- fluence of the different media varies widely across sub-disciplinary fields (finance, marketing, etc.). This articl…
