More Real Than Real : An Anthropological And Phenomenological Exploration Of Imagistic Sacred Space In The Contemporary Elegy And Fine Art Photograph., Amy Liann Tudor 1968-
More Real Than Real : An Anthropological And Phenomenological Exploration Of Imagistic Sacred Space In The Contemporary Elegy And Fine Art Photograph., Amy Liann Tudor 1968-
Electronic Theses and Dissertations
The creation of liminal spaces has been used for centuries cross-culturally to create sacred or taboo meanings in rituals, people, places, or objects. Liminality is constructed by the overlapping of cultural categories and "ruptures" an object or event's connotations, imbuing it with new and often transcendent or spiritually charged meaning. The photograph is an example of liminal space, since it freezes even the living in a state of corpse-like stasis. With the invention of this new medium, as well as its application to memorializing the dead, previous forms of commemorating death such as the eulogy and the poetic elegy were …

Molecular Engineering Design Of The Sapo-34 And Zif-8 Membranes For Co2 Separation From Ch4 And N2., Surendar Reddy Venna
Molecular Engineering Design Of The Sapo-34 And Zif-8 Membranes For Co2 Separation From Ch4 And N2., Surendar Reddy Venna
Electronic Theses and Dissertations
The separation of C02 from light gases is a very important environmental and energy issue. The state-of-the-art process for the purification of C02 uses amine adsorption, which is a complex, and costly. Membrane technology is far less expensive and requires less energy consumption. Although polymeric membranes can separate CO2, high pressures plasticize them and decrease their separation ability considerably. Zeolite membranes have significant advantages over traditional polymeric membranes, such as high thermal, mechanical, and chemical stability. Furthermore, the development of superior performance membranes for gas mixture separations requires novel materials with fundamentally different structural, adsorption and transport properties than those …

Signal Processing In The Tectothalamic Pathway., Haiyang Wei
Electronic Theses and Dissertations
The pulvinar is the largest nucleus of the human dorsal thalamus and is affected in a variety of brain disorders, such as schizophrenia. The experiments described in this dissertation elucidate key features of tecto-pulvino-cortical pathways as a first step toward understanding their role in coding visual stimuli and coordinating appropriate responsive actions. The tree shrew is used as the animal model because the visual structures of the tree shrew brain display many of the features of the primate brain, and the tectopulvinar pathways are particularly enhanced in this species. The connections formed between the tectorecipient pulvinar nucleus and cortex were …

Daily Emotional Experiences, Stress, And Ptsd Symptoms Among Midlife Women Exposed To Intimate Partner Violence : An Experience Sampling Study., Rebecca Ann Weigel
Electronic Theses and Dissertations
Described as important long-term consequences of trauma exposure, disruptions in emotional processes are regarded as central features of posttraumatic stress disorder (PTSD); however, the nature of these posttraumatic emotional disruptions remains poorly understood. The present study attempted to further understanding of these emotional disruptions by using experience sampling methodologies and electronic diaries to assess experiences of emotion, stress, and PTSD symptoms as they occurred in the day-to-day lives of midlife women exposed to intimate partner violence. Three sets of hypotheses were advanced and were tested using multilevel modeling approaches, with results demonstrating partial support for hypotheses overall. First, although past-month …
Adriamycin Nephrotoxicity Is Reduced By Metallothionein Over-Expression And Kidney Gene Expression Is Modified By Diabetes In The Ove26 Diabetic Model., Lu Yang
Electronic Theses and Dissertations
This thesis is divided into two parts below. Part I Adriamycin (ADR) can produce nephrotoxicity in rodents. The underlying mechanism may relate to ADR induced oxidative stress. In this study, we used transgenic mice (NMT3), which over-expressed the antioxidant protein metallothionein (MT) in podocytes, to study MT's protective potential on ADR nephrotoxicity. Urine and kidney samples were collected from control and transgenic mice at multiple time points after ADR injection, whose results showed that MT transgene alleviated ADR damage by reducing albuminuria, decreasing podocyte loss and protecting podocyte ultra-structure. Part II OVE26 mice are a good model of severe diabetic …

Inflammatory Cell Tumor Necrosis Factor Signaling Modulates Post-Infarction Left Ventricular Remodeling., Robert K. Lewis 1977-
Electronic Theses and Dissertations
The fundamental question of the exact nature of the role played by TNF in the failing myocardium remains one of contention. Many preclinical studies have demonstrated beneficial effects with TNF antagonism and recently the dichotomous role played by the two TNF receptors in chronic ischemic injury has come to light. The failing heart has also been determined to have low levels of inflammatory cell infiltration. As these cells are known to be potent producers of inflammatory cytokines, we hypothesized that inflammatory cell localized TNF receptors play an important role in the progression of LV remodeling following ischemic injury. To isolate …
The Social And Cultural Constructions Of The Self-Identity Of White American Corporate Businesswomen In Historiography, Literature, And Popular Culture (1963-1985)., Qin Ma 1974-
Electronic Theses and Dissertations
The purpose of this cross-disciplinary dissertation is to explore how the epistemic ruptures, such as WWII and the Second Wave Feminism, change the American society between 1963 and 1985. From a humanistic and historical point of view, it focuses on (l) the "self-identity" of modern white American corporate businesswomen (WACB) between 1963 and 1985, (2) the change of their self-identity in comparison with the historical period between 1920 and 1963, and (3) how their self-identity is socially and culturally constructed by analyzing evidence from 3 disciplines-historiography, literature, and popular culture. The major theories used for the hermeneutic interpretation of the …

Nanowire Based Materials And Architectures As Anodes For Li-Ion Batteries., Praveen Meduri 1982-
Electronic Theses and Dissertations
Energy independence requires that the nation reduce its dependence on foreign oil imports. This can be achieved through electrification of transportation vehicles if proper battery technology can be developed. In addition, the renewable energy sources such as solar and wind tend to be intermittent with time scales ranging from seconds to hours. So, a suitable energy storage technology is essential for integrating renewable sources for base load generation. Lithium ion battery technology is promising; however, the big challenge limiting its widespread implementation is with capacity, durability and safety. A dramatic advancement is needed in terms of materials used for both …

From Edmund Husserl's Image Consciousness To Maurice Merleau-Ponty's Flesh And Chiasm: The Phenomenological Essence Of Image., Sara J. Northerner
Electronic Theses and Dissertations
This dissertation presents the philosophical concepts of Edmund Husserl on phenomenology and image-consciousness and explores the phenomenological project of Maurice Merleau-Ponty as I have sought to render them in my creative artwork. By building upon Husserl' s theories on the phenomenological constitution of an object and his specific work with image-consciousness, the diverse structures of a contemporary image-consciousness are realized photographically in my artwork. His sketches, collected works and lectures provide a foundation of knowledge beyond traditional and contemporary photographic theory. Furthermore, Merleau-Ponty's writings on phenomenology, perception, embodiment and the visible/invisible have strengthened my ability to create diverse structures of …

Tobacco-Induced Changes To Porphyromonas Gingivalis Gene Expression, Phenotype And Host-Pathogen Interactions., Juhi Bagaitkar
Electronic Theses and Dissertations
Tobacco smoke is a strong and independent risk factor for several chronic systemic diseases and also increases susceptibility to a multitude of bacterial infections, including periodontal infections. Periodontitis is a chronic inflammatory disease of the supporting tissues of the periodontium caused by its chief etiological agent, Porphyromonas gingivalis . Smokers are more prone to persistent infections by P. gingivalis , and harbor higher numbers of P. gingivalis than non-smokers. However, smokers show reduced clinical signs of inflammation compared to non-smokers, making diagnosis of periodontal disease in smokers problematic. While several studies delineate the different mechanisms of how tobacco smoke alters …
Low-Frequency Repetitive Transcranial Magnetic Stimulation Modulates Evoked-Gamma Power, Event-Related Potentials, And Behavior In Autism Spectrum Disorders., Joshua Matthias Baruth
Low-Frequency Repetitive Transcranial Magnetic Stimulation Modulates Evoked-Gamma Power, Event-Related Potentials, And Behavior In Autism Spectrum Disorders., Joshua Matthias Baruth
Electronic Theses and Dissertations
Evidence suggests that cortical minicolumns are reduced in size and increased in number in individuals with autism spectrum disorder (ASD), especially in the dorsolateral prefrontal cortex (DLPFC). More specifically minicolumns in individuals with ASD are narrower and contain less peripheral, neuropil space; this may cause an increase in the ratio of cortical excitation to inhibition and adversely affect the functional distinctiveness of minicolumnar activation. A lack of cortical inhibition may cause signal/sensory amplification which can impair functioning, raise physiological stress, and adversely affect social interaction in patients with ASD. Additionally, the DLPFC forms a circuit interconnected with many areas of …
A Generic Framework For Context-Dependent Fusion With Application To Landmine Detection., Ahmed Chamseddine Ben Abdallah
A Generic Framework For Context-Dependent Fusion With Application To Landmine Detection., Ahmed Chamseddine Ben Abdallah
Electronic Theses and Dissertations
For complex detection and classification problems, involving data with large intra-class variations and noisy inputs, no single source of information can provide a satisfactory solution. As a result, combination of multiple classifiers is playing an increasing role in solving these complex pattern recognition problems, and has proven to be a viable alternative to using a single classifier. Over the past few years, a variety of schemes have been proposed for combining multiple classifiers. Most of these were global as they assign a degree of worthiness to each classifier, that is averaged over the entire training data. This may not be …

Development Of A Simulation And Evaluation Environment For A Traffic Flow Analysis System., Peter Bernhardt 1973-
Electronic Theses and Dissertations
A system for analysis of the traffic flow on public streets and highways through the use of Floating Car Data (FCD) relies completely on the number of simultaneously contributing vehicles, a fact that is no barrier for the phases of conception and development but poses a serious issue for the testing of such a system. Especially for smaller institutions or companies where the ability and resources to field the required number of participants is not given which in turn leads to the need for computational support to substitute the use of real vehicles by simulation. This thesis focuses on the …
Walking Biomechanics Of End Stage Knee Oa And Tka Patients., Danielle Biton
Walking Biomechanics Of End Stage Knee Oa And Tka Patients., Danielle Biton
Electronic Theses and Dissertations
Osteoarthritis (OA) of the knee is associated with decline in functional capacity and ultimately leads to Total Knee Arthroplasty (TKA) in many of these patients. Exercise regimens prior to surgery may potentially enhance pre and post TKA functional performance. However, assessment of such performance should involve biomechanical factors that characterize the mechanisms with which tasks are performed, and not just the quantity of task performed. The present overall study investigated walking biomechanics of end stage knee OA and TKA patients. Throughout the three sub-studies that comprised the overall investigation, particular emphasis was placed on heelstrike and the loading response phase …
Social-Cognitive Predictors Of Physical Activity Initiation In Type 2 Diabetes Following Diabetes Self-Management Education : Application Of The Health Action Process Approach., Jason E. Bonner
Electronic Theses and Dissertations
Type 2 diabetes presents a public health crisis and a global pandemic. Successful management of diabetes requires engagement in a daily regimen of self-care behaviors to achieve optimal glycemic control and to reduce the severity of diabetes-related complications. Regular engagement in physical activity has been demonstrated to improve glycemic control and overall quality of life among patients with diabetes. Diabetes self-management education (DSME) has become the hallmark for instructing patients with diabetes to engage in physical activity, yet physical activity patterns of DSME patients remains largely unknown. Further, it is unclear what factors could account for such behavior change in …

The Trickster, The Griot, And The Goddess : Optimal Consciousness In The Works Of Ntozake Shange, Kara Walker And India. Arie., Tiffany D. Caesar 1985-
Electronic Theses and Dissertations
The creative expressions of three black women artists--Ntozake Shange, Kara Walker, and India. Arie--are explored using optimal consciousness-an Afrocentric framework by Linda James Myers. This concept advocates that the role of the artist is to provide art that raises the consciousness of the people. An illustration of optimal consciousness will be demonstrated in their works by using the following criteria presented in the theory: authenticity, the fusion of sacred and secular, and positive interpersonal relationships. The creative works utilized for this analysis are Shange's choreopoem For Colored Girls Who Have Considered Suicide When The Rainbow is Enuf, Walker's silhouette narrative …

How Fares The Selective Tradition? : Racial Representation Of Characters In Second Grade Classroom Libraries., Nancy Franklin Hulan
Electronic Theses and Dissertations
This study investigated teachers' inclusion of racially diverse literature within their classroom libraries, how the representations within the literature compared with the students in the classrooms, the inclusivity of students' book selections, and teacher thoughts concerning selection of literature. Individual classrooms were found to fall within categories of challenging, progressing against, or continuing the selective tradition, the tendency of teachers to favor literature that primarily features White, middle-class, male authors and subjects over works by and about women and other ethnicities or social classes (Luke, Cooke, & Luke, 1986). Of 22 classroom libraries, three were challenging, three were progressing against, …
The Role Of Muc1 Splice Variants In Dry Eye And Inflammation., Yoannis Imbert-Fernandez
The Role Of Muc1 Splice Variants In Dry Eye And Inflammation., Yoannis Imbert-Fernandez
Electronic Theses and Dissertations
Mucin 1 (MUC1) is a plasma membrane-bound glycoprotein that plays a protective role in corneal epithelial cells. Two full-length splice variants of MUCl: MUCl/B and MUCl/A, that differ by the inclusion of 27 bp from intron 1 and a SNP in MUCl/A, but have identical C-terminal cytoplasmic domain (CD) sequences, were identified in human conjunctival tissue. I tested the hypothesis that MUC1 splice variants are key immunoregulators that act on the ocular surface to protect the ocular surface from inflammation and that their expression correlates with dry eye status. The expression of MUC1/A and MUCl/B splice variant was examined in …

A Manifestation Of All Life : Intersections Of Virtue Ethics, Philosophy Of Emotion, And Philosophy Of Literature., Derek Lee Penwell 1965-
Electronic Theses and Dissertations
This dissertation offers a brief survey of the rise of reason and the tum to the self at the expense of emotion in Western thought. This marginalization of emotion has had deleterious effects on two areas: the cultivation of virtue and the intersubjectivity necessary to sustain human flourishing. Using current research in neuropsychology the dissertation argues that reason and emotion form a dynamic partnership in the process of attaining reliable knowledge. Moreover, the dissertation argues that the emotional experience necessary for the cultivation of virtue, as well as the ability to attend to the emotional lives of others in the …
