This dissertation concerns the epic poem Caramuru (1781) by José de Santa Rita Durão. I propose both a post-nationalist or postcolonial reading of Caramuru, as well as a pre-nationalist or historical analysis. The first part of this dissertation focuses on the form itself, particularly the genre of epic poetry to which Caramuru belongs. The title of this dissertation references Virgil’s Aeneid, while the comparisons between this and other epics focus on the conventions of epic poetry, placing Caramuru within the context of other epic poems. Traditionally, and even recently, Caramuru has consistently been compared to Luis de Camões’ Os Lusíadas. I have tried to establish a closer connection with Virgil’s Aeneid, rather than Os Lusíadas, as the model epic for Caramuru. Chapter One focuses on the topic of imitation, specifically the many similarities with the plot of Virgil’s Aeneid. Chapter Two offers a historiographical approach to how the readings of colonial texts changed over time, including a historical background of Caramuru, which was written soon after the fall of the so-called enlightened despotism of Portugal under the Marques de Pombal. The second part of this dissertation is a close reading of the text itself, and focuses on the colonial discourse present in the poem. Chapter Three is an analysis of the religious discourse in Caramuru, which reflects the preoccupations of an Augustinian monk living in the Age of Enlightenment. Chapter Four concerns the representations of Amerindian resistance in the poem, particularly of two characters who belong to the insubordinate Caeté tribe. The last chapter focuses on the issue of gender and how women are represented in Caramuru. The main woman protagonist is a Tupinambá woman who becomes a prototype for Iracema, a well-known fictional character from nineteenth-century Brazil. Santa Rita Durão was born in Brazil but lived most of his adult life in Portugal, plus 15 years in Italy. He wrote that the motivation to write this poem was his ‘love of homeland’ or nationalist sentiment, even though the nation of Brazil was yet to exist at the time he wrote Caramuru. / text

Shifting patterns of precipitation associated with climate change may affect water-limited ecosystems to a greater degree than atmospheric CO2 or temperature changes, yet we lack a mechanistic understanding of the effects of water in these ecosystems. In water-limited ecosystems, annual net primary productivity correlates strongly with total annual precipitation. However, precipitation in these ecosystems arrives in episodic events, suggesting that biophysical investigations should focus on the implications of discrete precipitation events. Further, examining dynamics of ecosystem processes over a period of days or weeks promises to link our leaf-level mechanistic understandings with larger scale patterns and temporal dynamics of ecosystem photosynthetic CO2 uptake, respiration and evapotranspiration.The objectives of this dissertation were to quantify: (1) the influence of biotic and abiotic features of an ecosystem (e.g., species composition and soil physical characteristics) on short-term patterns of resilience and resistance to a precipitation pulse; (2) the role of antecedent climatic conditions and the seasonal timing of rainfall in limiting ecosystem carbon exchange in response to precipitation events; and (3) the effect of changes in woody plant abundance on seasonal ecosystem carbon dynamics in relation to the North American Monsoon.Major findings and contributions of this research include defining the concepts of ecosystem functional resistance and resilience and their implications in the presence of a dominant nonnative bunchgrass in semi-arid grasslands (Appendix A); a better understanding of the influence of warm-season precipitation variability and the seasonal timing of rainfall on ecosystem carbon dynamics in a semi-arid grassland (Appendix B); the use of flux duration analysis, a novel approach to analyzing ecosystem carbon and water flux time-series data to distinguish between "pulse-driven" or "steady-state" ecosystems (Appendix C); and, finally, the application of flux duration analysis to quantify the sensitivity of ecosystem carbon exchange in response to seasonal rainfall in a riparian grassland and shrubland and the role that plant functional type diversity may play in constraining carbon exchange sensitivity (Appendix D).

The traditional objectives of leadership conventions have been two-fold; First, the choice of a new party leader; second, the reaffirmation and renewal of party activists as well as unification of them behind the newly chosen leader. This thesis analyzes the Social Credit party leadership selection process with particular focus on the 1991 leadership convention. The study draws upon data and written material with respect to the 1986 leadership convention, but primarily information gathered from an extensive survey of behavior and attitudes of the nearly 1900 delegates to the 1991 leadership convention as well as newspapers and personal observation and interviews with attendees. It explores how the Social Credit party tried but failed to achieve both of the traditional objectives with their 1991 leadership convention. They chose a new party leader. However, entering the 1991 convention, the party was divided by numerous rifts which had developed during the 1986 leadership convention and since that event. Rather than heal the rifts, the 1991 leadership convention exacerbated them. Thus, as the 1991 leadership convention closed the party was more divided than when the year's leadership politics had begun.
