This dissertation deals with epistemological and literary problems surrounding Spanish Baroque reflection on the concepts of experience and perception, two of the most crucial and important notions linked to the origins of Western Modernity. Problems of experience and perception were treated by many Spanish philosophers and literary figures, including, Francisco Suárez....

This dissertation examines how amateur sports once dominated and controlled by Pennsylvanias Leisure Class became accessible to non-elites over the course of the twentieth century. Rising standards of living and increased leisure time were pre-requisites for broader public participation. But this study argues that the democratization of amateur sport depended on the act....

Chinas nation-building agenda in the early twentieth century embraced the causes of womens rights and medical modernization. Modernizers considered the poor health of the Chinese population to be a major impediment to progress. Specifically, modern midwifery would improve the health of the nation at its most fundamental level, both by lowering the high infant mortality ....

Efficient representations and solutions for large structured decision problems with continuous and discrete variables are among the important challenges faced by the designers of automated decision support systems. In this work, we describe a novel hybrid factored Markov decision process (MDP) model that allows for a compact representation of these problems, and a hybri....

This thesis is a study of physical fidelity in turbulence modeling. We first consider conservation laws in several popular turbulence models and find that of the Leray, Leray-deconvolution, Bardina and Stolz-Adams approximate deconvolution model (ADM), all but the Bardina model conserve a model energy. Only the ADM conserves a model helicity. Since the ADM conserves a ....

The behavioral consequences of norepinephrine (NE) in the basolateral amygdala (BLA) have long been well established. NE increases in the amygdala in response to the presentation of aversive stimuli, presumably due to an activation of locus coeruleus (LC) neurons that send NE efferents to the BLA. The following studies examine the electrophysiological consequences of al....

Oxidative stress induced by glutathione depletion in the mouse HT22 neuronal cell line and embryonic rat immature cortical neurons causes a delayed, sustained activation of extracellular signal-regulated kinases-1/2 (ERK1/2), which results in cell death. Previous studies from our lab have shown that this sustained activation of ERK1/2 is mediated primarily by a selectiv....

The main motivation is to investigate meson properties in the quark model to understand the model applicability and generate possible improvements. Certain modifications to the model are suggested which have been inspired by fundamental QCD properties (such as running coupling or spin dependence of strong interactions). These modifications expand the limits of applicabi....

Research on social support has produced conflicting results concerning the role that emotional expression by the victim plays in the process. The current study sought to clarify the role played by the type and intensity of the emotion displayed by the victim, and the relationship type desired by the potential support provider. Participants interacted with confederates d....

Although the caudate nuclei are involved in processing performance feedback, the specific conditions under which feedback engages the caudate are not well understood. It is unclear whether feedback in a declarative memory task can activate the caudate to the same extent as a non-declarative task. Likewise, it is not known how the type and amount of information carried b....

This dissertation is an examination of the problematic of Russian identity as manifest in the prose literature and cinema during the last two decades of the twentieth century. The reassertion of Russian national identity in the post-Soviet Russian Federation masks a crisis, the historical roots of which extend back to the development of Imperial Russia. The analysis emp....

The thesis examines the transition from post-revolutionary Soviet culture (1917-1928) to the culture of the Stalinsist period, arguing for a crucial transformation in the status of agency, subjecthood, and authorship between these two historical and cultural frames. I contend that Soviet culture has much to tell us about that momentous event of the twentieth century, th....
