This thesis uses the paleoceancirculation proxy ²³¹Pa/²³⁰Th, coupled with water mass tracers δ¹³C and εNd, to reconstruct circulation histories for southern source waters masses in the South Atlantic, in addition to North Atlantic Deep Water (NADW) far from its source, for the last ~25 kyrs. Downcore ²³¹Pa/²³⁰Th records from a suite of cores along a depth transect in the Argentine Basin show distinct differences with depth, suggesting that ²³¹Pa/²³⁰Th ratios in sediments are reflective of conditions in only the bottom most waters. This indicates the importance of consideration of changes in water mass distribution when interpreting ²³¹Pa/²³⁰Th records. Opal and particle flux data from these cores show little correlation with ²³¹Pa/²³⁰Th values meaning that changes in ²³¹Pa/²³⁰Th cannot be explained by a local composition or particle flux effect and are instead likely to be reflecting changes in circulation. A core bathed by Antarctic Intermediate Water (AAIW) throughout the last 25 kyrs (GeoB 2107, 1045 m), has relatively high ²³¹Pa/²³⁰Th values (0.075) during the Holocene and distincly lower values (0.055) at the LGM suggesting faster AAIW transport during the last glacial. At greater depths, ²³¹Pa/²³⁰Th, δ¹³C and εNd data in core GeoB 2109 (2504 m) indicate a change in both circulation and water mass distribution on glacial-interglacial timescales, with moderate flow of Antarctic Bottom Water (AABW) at the LGM being replaced by more vigorous flow of NADW during the Holocene. On millenial timescales, ²³¹Pa/²³⁰Th values in deep cores GeoB 2109 and GeoB 2112 (4010 m) indicate enhanced production of AABW during northern hemisphere stadials, when variations in ²³¹Pa/²³⁰Th records are of opposite sign between hemispheres, supporting a possible bipolar seesaw relationship in deep water formation between hemispheres. These data indicate that the ²³¹Pa/²³⁰Th proxy can be used to reconstruct past flow rates of multiple water masses in the Argentine Basin and provide evidence that southern source water masses play a dynamic counterpart to NADW formation on abrupt as well as glacial-interglacial timescales.

The circo criollo, or Argentine native circus, arose as one of the most important forms of popular expression during the late nineteenth century. This performance context can serve as a site for exploring old and new constructions of Argentine identity that encompassed the lower and middle classes and included native and immigrant groups, particularly in Buenos Aires. Although the native circus contributed greatly to the creation of such an identity, little is known about the musical practices of the circus itself, including what types of music or dance were performed, the manner in which they were interpreted, and how the audience responded. This thesis therefore aims to bring to light these previously obscure circus traditions. It discusses the negotiation and conflict of power relationships that informs Argentine identity construction within this popular expressive medium. By examining the circo criollo as a site of hegemonic power differentials, this study probes more deeply into the contradictions that underlie such a fragile yet persistent sense of incipient Argentine identity.

During the past decade, Lucrecia Martel has emerged as the most respected filmmaker from South America. This thesis is motivated by my conviction that Martel's films are worthy of serious engagement and critical scrutiny. It is also motivated by my curiosity about the seemingly inexhaustible pleasure and edification I derive from them. Martel describes her filmmaking as "cine de autor" (auteur cinema). Indeed, her films evidence a personal involvement in every aspect of filmmaking. This thesis will define and explore the characteristics and conditions of her authorship. This thesis constitutes an expression of the enduring usefulness of auteurist criticism. In this case, this critical approach is entirely appropriate and likely to yield the deepest insights into the films. The introduction to my thesis provides pertinent biographical information and the necessary socio-cultural context to set the stage for an intellectual immersion into her three features to date: The Swamp (2001), The Holy Girl (2004) and The Headless Woman (2008). I propose that these films constitute a trilogy that distills Martel's experience of growing up in the remote province of Salta and critiques the social and cultural forces at play in provincial Latin American life. However, no matter how specific the sense of place the films convey and how grounded they are in subjective experience, they illuminate universal aspects of being a person in the world and contain progressive prescriptions for living from which anyone can benefit. My research into the literature on the films of Lucrecia Martel failed to find any serious and thorough appraisal of Lucrecia Martelâ??s films as a trilogy. While my analysis benefits from familiarity with the available literature, the operative critical approach privileges my direct experience with the audiovisual material provided by the films. Each film will be subjected to a close reading illustrated with images from it. These readings focus sharply on certain sequences I deem crucial to the conveyance of characterization, meaning and ideology. These readings aim to think with the films rather than think against or about them. They explore the themes and issues that arise within the narratives of the films as well as the formal means by which they do.

L'objectif de ce mémoire est d'examiner le rôle du capital social durant l'explosion sociale et politique de 2001 en Argentine, année qui constitue l'aboutissement d'un processus de mobilisation collective entamé au cours des années 1990. Cette crise marquée par la marginalisation sociale, la pauvreté, le chômage et la perte de repère politique a plongé l'Argentine dans une misère généralisée. Contre toute attente, les Argentins se sont rassemblés, et ont envisagé diverses façons de résoudre leurs problèmes collectivement en réponse au vide politique et social. Malgré la confiance politique atteignant les bas-fonds, une confiance sociale généralisée à la baisse et une démocratie récente, les Argentins ont su se rassembler et travailler ensemble. Nous soulevons le paradoxe entre la théorie du capital social traditionnel et l'éveil du capital social constaté au cours des années 1990 et menant à la crise de 2001-2002 en Argentine. Notre recherche permet de conclure que le capital social est contextuel, dans le cas argentin, associé à la conjoncture politique, sociale et économique menant à la crise argentine de 2001-2002. Nous soulignons l'importance des institutions politiques, irremplaçables malgré les efforts d'autogestion de la société civile. De plus, nous constatons que le capital social survient de façon ponctuelle et s'avère éphémère. À plus long terme, une fois l'état de crise estompé, les associations volontaires se démobilisent et s'orientent vers des objectifs plus personnels que collectifs. Nous appuyons notre recherche par une combinaison de recherche théorique et empirique, notamment par la recherche de terra in réalisée à Buenos Aires en 2010. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Argentine, Capital social, Associations collectives, Crise de 2001, Confiance sociale généralisée, Confiance politique, Démocratie.
