Seismically induced rock slope failures have resulted in billions of dollars of economic damage and enormous loss of life throughout the world. Accurate prediction of the triggering and run out of these failures is elusive for a variety of reasons, including knowledge of the physical modes of failure. Simplified tools that are prevalent in soil slope engineering are relatively non-existent in rock slope engineering. Current state of art in rock slope engineering requires complex and computationally expensive numerical models to evaluate the seismic performance or rock slopes, which inhibits extensive evaluations to be conducted. This research explores the potential failure modes of an idealized rigid rock block and expands the modes typically considered to include not only sliding but also toppling (pure forward rotation), confined toppling (constrained forward toppling) and slumping (combined backward rotation and translation). The yield acceleration (or minimum inertial acceleration to cause block movement) for slumping, similar to toppling, is found to be lower than for pure translational sliding. These yield accelerations indicate the initial modes of rock block failure; however, they do not always predict the ultimate failure mode. To predict the final failure modes, the results of discrete element numerical analyses were compared to pseudo static yield acceleration to develop a seismic failure mode chart based on block geometry and interface friction. For co-seismic displacement predictions, simplified models predicting ultimate displacement of a mass under seismic conditions are limited to purely translating, sliding blocks (i.e.\ Newmark's sliding block method). This dissertation introduces additional non-linear, time-dependent models to predict ultimate displacement in toppling and slumping modes as well. Similarities of the dynamic response of rocking, toppling, and slumping systems are exposed and allow knowledge from the well-established literature of rocking blocks to be leveraged. The parameters of these non-linear models are combined such that mapping of more complex systems to these simple models can be performed. Important findings from these new methods are that the magnitude of seismically-induced displacement is dependent on the size and shape of the block (or failure mass) and the displacement dependent yield accelerations. In addition, by establishing a failure criteria for the different modes of failure, ground motion characteristics (mean period and intensity) can be used to predict the likelihood of failure. Design charts are developed to allow seismic toppling and slumping failures to be integrated into PBEE evaluations or real-time regional assessments.

Scholars of Caribbean slavery have long been interested in the informal economic activity in which the enslaved engaged, localized in provision grounds, housegardens, and Sunday markets. These pursuits, independent from plantation-based monocrop agriculture, provided for the subsistence needs of the enslaved and compensated for a lack of provisioning by planters. Such economic activity by the enslaved is commonly linked to the development of strong social and economic networks which facilitated post-emancipation transitions to subsistence agriculture or a peasant economy. Much of the research on these topics, however, has been focused on the former British colonies. This dissertation examines the social and economic lives of laborers on a French Caribbean plantation, Habitation La Mahaudiere, in the northern Grande-Terre commune of Anse-Bertrand in Guadeloupe. Using archival and archaeological evidence, I examine the long-term history of the laborer's village, spanning the mid-eighteenth through the early-twentieth centuries. I use information collected through excavations of five household structures to establish diachronic comparisons of the domestic economies of village inhabitants. I analyze the negotiation of social relations of power in everyday practice through a close consideration of architectural remains, artifact assemblages, and the documentary evidence from an 1840s court case against estate owner, Jean-Baptiste Douillard-Mahaudiere. This evidence suggests the importance of the local context and the particularities of the French colonial setting to an understanding of the practice of slavery in the colonies. I demonstrate the impact of turbulent historical circumstances on the day-to-day lives of laborers, and examine the entanglement of material culture in these processes.

Rewriting History: Carolingian Reform and Controversy in Biographies of Saints

The reforms of Carolingian kings and emperors, and the controversies that arose from these reforms, subtly but profoundly shaped the biographies of holy men and women as they were revised during the ninth century. A number of revised saints' lives and their earlier versions survive and a close comparison of the earlier versions with their revisions reveals that the revisers made far more important changes to the content than has been recognized. This study uncovers a wealth of previously unnoticed ninth-century evidence whose deep significance emerges from comparison with contemporary sources. The rewriting phenomenon, which is explored through historical and literary approaches to rewriting and translation, appears as the embodiment of the Carolingian goal of correcting learning and behavior. The dissertation looks at reforms from ca. 800 to ca. 870 in several areas: orthodox belief, monastic reform according to the Rule of Saint Benedict, and kingship, specifically the heightened moral expectations for rulers' behavior in the bedroom and on the battlefield. In addition to new constructions of sanctity, the revisers changed other aspects of the saints' worlds that they invented: bishops, monks, kings, queens, and even the landscape. Hagiography appears deeply influenced by the author, audience, and events at the time of revision and different retellings of the same story allow us to track changing ideals from century to century as well as decade to decade. My work sheds new light on the reform movement and on some of its most prominent exponents (Alcuin, Jonas of Orleans, Walafrid Strabo, Lupus of Ferrieres, and Ado of Vienne) from the largely neglected perspective of their hagiographical work. Their revisions reveal that some are far more creative, clever, and controversial than previously thought and highlight the interests that characterized each successive generation of the Carolingian renaissance. My conclusion suggests that the study of thematic rewriting helps us to learn more about the authors of anonymous texts like those of saints Balthild and Genevieve.

This study explores the thoughts and lived experiences of a two groups of black adolescent girls, as they create and enact their class, race, and gender identities, at an urban and suburban high school. The project, a qualitative study using participant observations, and individual and focus group interviews, reconstructed how the participants' gender and racial identities are shaped within their respective educational institutions and how their interactions within their high schools become a part of their identity development. This study contributes to the research literature in that there is limited research that solely focuses on black teenage girls' gender and racial identity construction within educational institutions. When black females have been included in studies it has been in relation to their black male and white female counterparts; and often from white scholars' viewpoints. The results showed that the black female participant's gender and racial identities are affected academically and socially by attending an urban and a suburban public high school. This study gave voice to black adolescent females attending an urban and suburban high school and demonstrated that there is a need for this type of research not only in public schools, but in private educational institutions where black female's voices have been silenced and still continues in the twenty-first century.
