The Rhetoric Of Picasso, Matthew R. Sharp
The Rhetoric Of Picasso, Matthew R. Sharp
Theses and Dissertations
Pablo Picasso was arguably the most famous and controversial artist of the twentieth century, and some of his most famous pieces were created during the Spanish Civil War (1936-1939) in response to the horrible atrocities taking place in his homeland. "The Rhetoric of Picasso" by Matthew R. Sharp, filed December 2007, examines some of these works—including paintings such as Guernica and Weeping Woman —and theorizes their rhetorical force, using speech act theory as the theoretical lens. Based on common images and themes in Picasso's symbolism, it is determined that Picasso's works during the Spanish Civil War are expressive speech acts …

Transitions: Starting The Second, Full Circle, Mary Colleen Vreeland
Theses and Dissertations
This thesis will focus on the transitional influences that have led me to start the second circle of my professional life. It is an open and honest exploration of the back-story of my life and the academic and professional influences that led me to seek a Master of Fine Arts Degree at Virginia Commonwealth University. With no parallels and therefore no excuses insinuated, I will be open and dissect more of myself as the whole focus of the thesis in hopes of offering clarity to myself and other mature and disabled students seeking to become a better teacher and artist.
Cannabinoid Modulation Of Chemotaxis Of Macrophages And Macrophage-Like Cells, Erinn Shenee Raborn
Cannabinoid Modulation Of Chemotaxis Of Macrophages And Macrophage-Like Cells, Erinn Shenee Raborn
Theses and Dissertations
Exogenous and endogenous cannabinoids have been reported to modulate functional activities of macrophages. It is recognized that macrophages express primarily the CB2 cannabinoid receptor, but recent studies indicate that its expression is differential in relation to activation state with maximal levels occurring when cells are in "responsive" and "primed" states. The functional activities of macrophages when in these states of activation are the most susceptible to the action of cannabinoids, at least in terms of a functional linkage to the CB2. To assess the effect of cannabinoid treatment on macrophage chemotaxis and test the hypothesis that cannabinoids inhibit the chemotactic …
Stress And Anxiety In Adhd: Links To Sensory Over-Responsivity, Stacey E. Reynolds
Stress And Anxiety In Adhd: Links To Sensory Over-Responsivity, Stacey E. Reynolds
Theses and Dissertations
Sensory Modulation Dysfunction (SMD) is characterized by an inability to consistently and accurately grade responses to sensory information. SMD, and specifically sensory over-responsivity (SOR), has been correlated with stress and anxiety in some developmentally delayed populations and has been associated with structures and functions of the hypothalamic-pituitary adrenal (HPA) axis. Recent attention has been given to HPA functioning in children with Attention Deficit Hyperactivity Disorder (ADHD), with a majority of studies identifying blunted or diminished cortisol patterns. In contrast, elevated cortisol has been associated with anxiety and anxious behaviors in both animal and human studies. The purpose of this study …

Times New Roman, Jason Mckrindey Coates
Theses and Dissertations
It is difficult to say that anything will be proven in this thesis of mine. I think of it more as an account of some things that happened in my artwork over the course of graduate school and my earlier development as an artist. Some influences are listed, but certainly not all of them. Likewise, the work that is mentioned in this paper represents a sampling rather than an in-depth survey. I don't have any tables or charts.

Evaluation Of The Nutritional Quality Of Twelve Species Of Grass Tolerant To Salt And Drought In Function To Their Dry Matter Accumulation Curve In The Tamborada Region, Julio César Bustamante Alavi
Theses and Dissertations
Currently, livestock production in the Andean highlands of Bolivia is done with low food efficiency due to the free range grazing system. This in turn leads to nutritional deficiencies. Therefore, it is necessary to substitute these grass species for others that fulfill nutritional requirements. Our main objective was to determine the species of grass with the best nutritional quality. Of the 12 species, only 11 were analyzed because the species Didtichlis stricta did not germinate. Five monthly samples were taken after the cut (ddc) at the following intervals: 50, 81, 112, 141, and 176 days. These samples were analyzed in …

Exploring The Ligand Binding Site On The Dopamine Transporter By Photoaffinity Labeling And Site-Directed Mutagenesis, Maria Laura Parnas
Theses and Dissertations
The dopamine transporter (DAT) is a neuronal presynaptic transmembrane protein that clears released dopamine (DA) from the synaptic space, regulating the neurotransmitter concentration and availability, DAT and the related serotonin (SERT) and norepinephrine (NET) transporters belong to the SLC6 family of Na+ and CI- dependent symporters, and are major targets for the action of several drugs, including the psychostimulant cocaine. DAT is predicted to possess 12 transmembrane spanning domains (TMs), with both N- and C-termini located intracellularly. Extensive research efforts to gain insight on the molecular aspects of DAT have been attempted, but the three-dimensional arrangement of the protein as …

An Environmental Complexity Analysis For Robot-Environment System Design, Gang Yang
An Environmental Complexity Analysis For Robot-Environment System Design, Gang Yang
Theses and Dissertations
Recently, researchers have begun to investigate intelligent environments for robot applications. In this work, a robot and its work environment can be considered to be an integrated system. Currently, such robot-environment systems are designed on an ad-hoc basis, with the final performance of the system greatly dependent on the experience and preferences of the designer. This dissertation investigates a way to improve on this situation by looking at the complexity of an environment from the perspective of a robot. The objective of this research is to develop a method to evaluate environmental complexity and then use this information to help …
Giant Pandas Balance Energy Budgets With Metabolic Depression: Insights From Radar Detection Of Heart Rates, Tommy Gene Finley
Giant Pandas Balance Energy Budgets With Metabolic Depression: Insights From Radar Detection Of Heart Rates, Tommy Gene Finley
Theses and Dissertations
Giant pandas ( Ailuropoda melanoleuca ) are flagship species for conservation because of their endangered status and charismatic nature. Giant pandas are placed in the bear family (Urisidae) within the order Carnivora. They specialize on a diet of bamboo, yet retain a typical carnivore gastrointestinal tract. Low energy digestive efficiency (9.5–34%) was calculated from bamboo-only digestibility trials conducted on captive giant pandas. Huge amounts of bamboo are consumed to overcome inefficient extraction and thus obtain sufficient energy and nutrients. I designed this study to gain insights into giant panda energy balance by measuring heart rates during sleep, their primary means …

Supporting Personhood In Dementia: Examining The Impact Of Volition On Function In Everyday Occupations, Christine L. Raber
Supporting Personhood In Dementia: Examining The Impact Of Volition On Function In Everyday Occupations, Christine L. Raber
Theses and Dissertations
Understanding volition and preferences for occupation is a critical underpinning of effective occupational therapy services that promote and preserve identity for persons with moderate dementia. Although it has been posited that this population has significant difficulty expressing volition for daily occupations, little research has examined the role of volition in guiding engagement in occupations. This phenomenological study provides an in-depth description and analysis of volition in eight persons with moderate dementia. Guiding questions related to understanding patterns of past life interests, outward demonstration of volition, volitional continuity. and the relationship of the social environment to volition and engagement in daily …
Roles And Attitudes Of Males And Females In The Anarchist Punk Community, Donna M. Manion
Roles And Attitudes Of Males And Females In The Anarchist Punk Community, Donna M. Manion
Theses and Dissertations
Sexism is a widespread social problem that exists throughout the world today. It persists within the dominant culture, as well as in various subcultures, including the punk subculture (Daugherty 2002; Leblanc 1999; McRobbie 1991; Rosenberg and Garofalo 1998). Nijole Benokraitis and Joe Feagin's (1995) theory of sexism posits that subtle sexism is the unequal and harmful treatment of women that is typically less visible than blatant sex discrimination. This particular type of sexism may often go unnoticed, as society has internalized subtle sexist behaviors. Empirical research on subtle sexism has been conducted in various settings, such as the employment, academic, …

On The Binding Of N1-Substituted Tryptamines At H5-Ht6 Receptors, Abner Nyamwaro Nyandege
Theses and Dissertations
Serotonin was first discovered in the late 1940s as a vasotonic factor and is now considered a principal neurotransmitter in the nervous system. 5-HT6 receptors are one of the most recently identified members of the serotonin receptor family which consists of seven classes (5-HT1-5-HT7). 5-HT6 receptors are G-protein coupled, positively coupled to an adenylate cyclase second messenger system and are primarily found in the central nervous system (CNS). The exact functional role of 5-HT6 receptors has not been determined, but is implicated to have possible involvement in certain neuropsychiatric disorders and cognition. To investigate the functional role of these receptors, …
Camping In The Classroom: Ridiculous Theatre As Serious Drama, John Kenneth Deboer
Camping In The Classroom: Ridiculous Theatre As Serious Drama, John Kenneth Deboer
Theses and Dissertations
My first semester pursuing my MFA in Voice and Speech Pedagogy I vocal-coached an openly gay student playing a straight character who would mask his sexual identity in such a manner that his performance became stiff and uninteresting. Rather than using his personal identity as an asset in the pursuit of a successful performance, his chosen vocal tactics removed any sense of theatricality from his performance. I confronted the student and suggested such extreme vocal suppression diminished the quality of his overall performance. He replied, "So you want me to get the gay out."His use of the phrase, "get the …

Electrospun Blends Of Polydioxanone And Fibrinogen For Urological Applications, Joshua Ford Grant
Theses and Dissertations
The need for tissue and organ replacements cannot be satisfied by autograft and allografts alone. The purpose of this study was to investigate the feasibility of electrospinning a blend of polydioxanone and fibrinogen to produce an engineered tissue scaffold. Fiber diameter and pore size of blends were characterized, as well as mechanical strength. Cell proliferation assays for 1 and 7 day cultures were preformed, and a histological evaluation was performed to determine how favorable the various blends were to cell infiltration and proliferation. Some ratios of blends were identified that contained both acceptable mechanical properties and properties that facilitated cell …

One Million Paintings 2005-2007: A Thesis, Jared Lindsay Clark
Theses and Dissertations
I assist discarded collectives of objects to volunteer themselves for inclusion into the privileged legacy of flatness – assuring them they can be transformed into Painting. Reducing my interventions - often to mere arrangement - respects the possibility of this transformation while frankly retaining the objects' original functional identities. Every surface of any object is a readymade painting – especially flat ones. By stacking objects and aligning their surfaces on one privileged side into a flat mega-surface, I am composing and collaging – even building – a painting. With my amateur interest in German I latch upon the double meaning …
