TL;DR: In this article, major and selected trace element (Al, Fe, Mg, K, Ba, P, Mn, V, Cu, Ni, and Ti) records were analyzed in two cores recovered from the northwestern Indian Ocean (core MD 90940 on the Madingley Rise and core MD 85668 in the Somali Basin) in order to monitor the sedimentary response to pelagic productivity in this area during the last 400,000 years.

TL;DR: In this article, a bilan des savoirs sur la question and, au-dela, quelques pistes de recherche afin de depasser certaines apories theoriques and methodologiques.
Abstract: Resume Les printemps arabes ont remis sur le devant de la scene une vieille interrogation des theories de l’action collective : la repression stimule-t-elle ou annihile-t-elle la mobilisation ? Cet article se propose de dresser un bilan des savoirs sur la question et, au-dela, de proposer quelques pistes de recherche afin de depasser certaines apories theoriques et methodologiques L’article s’attelle a la tâche de comprendre les effets de causalites entre mobilisations protestataires et repression, et ce, dans une perspective macro-sociologique et dynamique Les auteurs proposent de placer la focale de l’analyse a l’echelle meso et micro : celle des organisations militantes et des carrieres militantes individuelles

TL;DR: In this article, a review of the vast literature devoted to this question is presented, and a meso-and micro-level approach that puts analytical emphasis both on protest organizations and on individual activists' careers is proposed.
Abstract: The recent wave of upheavals and revolts in Northern Africa and the Middle East goes back to an old question often raised by theories of collective action: does repression act as a negative or positive incentive for further mobilization? Through a review of the vast literature devoted to this question, this article aims to go beyond theoretical and methodological dead-ends. The article moves on to non-Western settings in order to better understand, via a macro-sociological and dynamic approach, the causal effects between mobilizations and repression. It pleads for a meso- and micro-level approach to this issue: an approach that puts analytical emphasis both on protest organizations and on individual activists’ careers.

TL;DR: In this paper, the authors describe a retour au principe d'unite des sciences sociales, seul moyen de ne pas se couper de pans entiers de la recherche en train de se faire and d'avoir quelque chance d'ouvrir de nouvelles questions.
Abstract: En quoi consiste aujourd’hui la pratique du chercheur etudiant les mouvements sociaux ? Comment stimuler l’imagination sociologique au moment ou se manifeste une triple routinisation des objets, des schemes d’interpretation et des arts de faire methodologiques dans ce domaine des sciences sociales ? Il ne s’agit pas ici de ceder a certaines formes de « methodologisme » en proposant une methode, ni a fortiori « la bonne methode » d’etude des mobilisations, detachee des enjeux de connaissance propres a chaque recherche specifique. Plutot qu’un durcissement methodologique ou la promotion d’un modele standardise d’approche empirique des mobilisations, l’article et le dossier appellent a un retour au principe d’unite des sciences sociales, seul moyen de ne pas se couper de pans entiers de la recherche en train de se faire et d’avoir quelque chance d’ouvrir de nouvelles questions. Penser et regarder autrement les mobilisations, c’est ce a quoi invitent donc les chercheurs reunis dans ce numero, en suggerant en particulier de mieux prendre en compte l’inscription des mobilisations dans le temps, l’espace et l’ordre social.

TL;DR: Aclarar los terminos del deba-te sobre el clientelismo and proporcionió una revision de la literatura internacional sobre the tema and aportar pistas de investigacion for ubicar que esta en juego en un pais como Mexico as discussed by the authors.
Abstract: El termino “clientelismo” es objeto de debates y ha recibido multiples definiciones en los ultimos anos. Algunos investigadores lo utilizaron para describir cierto tipo de relaciones que ocurren en el seno de sistemas politi-cos especificos; otros lo usaron para dar cuenta de los vinculos de dependencia entre el personal politico y su electorado en sociedades muy distintas; otra postura conduce a descartar el termino para enfatizar que el “intercambio en politica” es un rasgo esencial de todos los sistemas politicos y no esta necesariamente asocia-do a relaciones de tipo vertical entre patrones y clientes. Este articulo propone aclarar los terminos del deba-te sobre el “clientelismo” y proporciona una revision de la literatura internacional sobre el tema y aportar pistas de investigacion para ubicar que esta en juego en un pais como Mexico.

Journal ArticleDOI
TL;DR: In this paper, a synthesis of the use of selected trace elements as proxies for reconstruction of paleoproductivity and paleoredox conditions is presented, and the combined used of U, V and Mo enrichments may allow suboxic environments to be distinguished from anoxic-euxinic ones.

TL;DR: In this paper, the accumulation rates of three commonly used proxies for productivity from a set of primarily Quaternary sediment cores at 94 marine sites, compiled from 37 published sources, were evaluated for total organic carbon, organic phosphorus, and biogenic barium (Babio).

TL;DR: In this paper, the authors explore the links between land ownership contention, private violence and the state in Colombia and present a context where criminal actors participate in the regular functioning of public institutions.
Abstract: This study explores the links between land ownership contention, private violence and the state. Colombia presents a context where criminal actors participate in the regular functioning of public institutions. The study rejects normative conceptions about the link between criminal actors and the state. Crime and violence are not considered as extraneous factors, separated from the political game; they are analyzed as constitutive of logics of competition, accumulation and economic development, ultimately, elements in the process of state formation.

TL;DR: In this article, the authors quantified benthic foraminifera in sediment cores from a topographic high (Murray Ridge) in the northern Arabian Sea, and showed that changes in the intensity of the OMZ, linked to monsoonal climate variability, had a strong impact on benthicle foraminiferal composition and accumulation rates.

TL;DR: In this paper, the authors investigated the forcing mechanisms for dust input and wind strength in the North Canary Basin, the temporal pattern of variability of sedimentological and geochemical proxy records has been analysed in two sediment cores between latitudes 30°30′N and 31°40′N.
