Politisations différentielles et acculturations mutuelles en contexte autoritaire : ethnographie d'une inversion du cens électoral

Français L'observation ethnographique des politisations différentielles pendant une campagne électorale en contexte autoritaire changeant est un analyseur privilégié de plusieurs processus. Sur un plan empirique, elle donne à voir les modalités diversifiées d'appropriation du moment électoral par les acteurs, les tentatives d'ajustement d'une partie de la gauche marocaine à la perte de son électorat de granit et aux transformations du marché électoral, mais également un mouvement de fond : celui de l'inversion ponctuelle du principe censitaire, en lien avec la désertion des urnes par les plus dotés culturellement et matériellement et avec la mutation du vote urbain populaire. Sur un plan théorique, l'examen des tâtonnements en oeuvre - avant leur naturalisation - permet de poursuivre le dialogue entre les travaux sur le clientélisme politique et sur la politisation, au croisement des approches socio-historiques et de sociologie politique, en contextes autoritaires et démocratiques. Il montre l'intérêt de dépasser les oppositions entre conceptions restrictives et extensives de la politisation, pour se saisir processuellement et in situ des politisations différentielles des acteurs, des registres et des pratiques. English Differential Forms of Politicization and Mutual Acculturation in an Authoritarian ContextThe ethnographic observation of differential forms of politicization during an electoral campaign in a changing authoritarian context is an ideal means of analyzing a number of processes. Empirically, it enables us to observe the actors' diverse ways of appropriating the electoral moment, a Moroccan leftist party's attempts to adjust to the loss of its electoral base and the transformations of the electoral market. It also enables us to observe a one-time reversal of the symbolic voting restrictions, in correlation with the desertion of the polls by the those best equipped to participate, both culturally and materially, and with the transformation of the urban popular vote. In theoretical terms, examination of such ongoing processes - before their stabilization - allows us to follow the interplay between the work on political clientelism and on politicization, at the intersection of sociohistorical and political sociological approaches, in authoritarian and democratic contexts. It demonstrates the value of moving beyond the opposition between restrictive and extensive conceptions of politicization, to grasp the process in situ of differential forms of the politicization of actors, registers and practices.

Thinning of the Goban Spur continental margin and formation of early oceanic crust: Constraints from forward modelling and inversion of marine magnetic anomalies

The deep seismic reflection profile Western Approaches Margin (WAM) cuts across the Goban Spur continental margin, located southwest of Ireland. This non-volcanic margin is characterized by a few tilted blocks parallel to the margin. A volcanic sill has been emplaced on the westernmost tilted block. The shape of the eastern part of this sill is known from seismic data, but neither seismic nor gravity data allow a precise determination of the extent and shape of the volcanic body at depth. Forward modelling and inversion of magnetic data constrain the shape of this volcanic sill and the location of the ocean-continent transition. The volcanic body thickens towards the ocean, and seems to be in direct contact with the oceanic crust. In the contact zone, the volcanic body and the oceanic magnetic layer display approximately the same thickness. The oceanic magnetic layer is anomalously thick immediately west of the volcanic body, and gradually thins to reach more typical values 40 km further to the west. The volcanic sill would therefore represent the very first formation of oceanic crust, just before or at the continental break-up. The ocean-continent transition is limited to a zone 15 km wide. The continental magnetic layer seems to thin gradually oceanwards, as does the continental crust, but no simple relation is observed between their respective thinnings.

LAS TRAMPAS DE LA FALSA MODERNIZACIÓN DE LA GESTIÓN PUBLICA COSTARRICENSE: CONSIDERACIONES ALREDEDOR DE LA TEMÁTICA ENERGÉTICA 1995-2000

En la ponencia se trata de vincular el contexto de la denominada modemización de la gestión pública costarricense, referido al campo energético y de telecomunicaciones. En la ponencia se enfatiza el contexto histórico en que este proceso surge, los cambios que suceden en la década de los 90, demostrando cómo una serie de acciones llevaron a la inmovilidad en relación con la institución eje en dicha materia: el Instituto Costarricense de Electricidad. En el trabajo se hace un esfuerzo para ubicar el proyecto de modernización del ICE, enfatizando los errores cometidos, así como parte del debate en relación con dicha área, de la misma manera se sitúa la respuesta de una parte importante de la sociedad civil, demostrándose que la sociedad civil consideró inoportuno tanto la forma como el fondo del tratamiento en este caso.
