Una sociedad legalista: Abogados, procuradores de causas y la creación de una cultura legal colonial en Lima y Potosí, 1540–1670

This study deals with the formation, reproduction, and the role in litigation of two branches of the legal profession, lawyers and procurators. They were the experts in charge of civil, criminal, and ecclesiastical litigation during the Old Regime. While the lawyers provided erudite legal advice, procurators oriented and drove the procedure as legal representatives of their clients. The European legal revolutions of the twelfth and thirteenth centuries forged a new legal culture in which the lawsuit was reputed to be the best way to settle disputes. Likewise, that legal culture conferred an important place to specialists as legal facilitators of the contending parties. When Castilians exported their legal system to the New World, they spread a complex and bureaucratic framework, contributing to the reproduction of a class of experts in urban spaces. Lima and Potosi, two urban centers created in the sixteenth century, quickly became significant ‘legal cities’. This dissertation explores how the legal markets of these cities operated, the careers of their specialists, their professional options, social images regarding them, and litigation costs. This study examines the careers of 267 facilitators and demonstrates that they constituted a class of distinctive legal professionals. Legal culture embodies the representation and use of law. The closeness of specialists with litigants, in particular of procurators familiarized the parties with litigation and its complex processes. These specialists forged dominant legal discourses and manipulated juridical order. Litigants were not passive agents of their specialists. Caciques and members of the Hispanicized communities appropriated the law in a visible way as the growing litigiousness illustrates. Colonial law (of a pluralistic basis) was an arena of assertion and discussion of rights by different social actors, encomenderos, leading citizens, widows, native chieftains, artisans, and commoners. This study concludes that this struggle and manipulation served to legitimate the role of those legal experts and gave birth to a complex legalistic society in the Andes under Spanish Habsburg rule.

Mechanism of Superoxide Mediated Regulation of Particle Uptake and Exocytosis by a GPI-anchored Superoxide Dismutase C in Dictyostelium

Dictyostelium discoideum is a simple model organism that can be used to study endocytic pathways such as phagocytosis and macropinocytosis because of its homology to cells of the mammalian innate immune system, namely macrophages and neutrophils. Consequently, Dictyostelium can also be used to study the process of exocytosis. In our laboratory, we generated Dictyostelium cells lacking superoxide dismutase SodC. Our data suggest that cells that lack SodC are defective in macropinocytosis and exocytosis when compared to wild type cells. In this study I describe a regulatory mechanism of macropinocytosis by SodC via regulation of RasG, which in turn controls PI3K activation and thus macropinocytosis. Our results show that proper metabolism of superoxide is critical for efficient particle uptake, for the proper trafficking of internalized particles, and a timely exocytosis of fluid uptake in Dictyostelium cells.
