Exploring Classical And Contemporary Conception Of Ethos Applied Case-The Rhetorical Ethos Of President George W. Bush, Bobby J. Antrobus

Theses and Dissertations

By exploring classical and contemporary conceptions of rhetorical ethos, this thesis assembles theories of analysis and then applies them in the form of rhetorical analysis of the rhetorical ethos exhibited by President George W. Bush in his presidential speeches. The theoretical investigation reveals the extensive use of the ethical appeal in all manner of rhetorical situations in the contemporary world but especially focuses on how political rhetoric has come to rely predominantly on this persuasive appeal. The study examines several speeches given by President Bush and concludes that his success as president is attributed largely to the sophisticated rhetorical strategies …

Type-5 Phosphodiesterase Inhibition In The Prevention Of Doxorubicin Cardiomyopathy, Patrick William Fisher

Theses and Dissertations

Prior studies have demonstrated the effect of diazoxide in protecting against apoptosis via mitochondrial KATP channel opening in vitro. The current investigations are designed to determine if sildenafil, a phosphodiesterase-5 inhibitor and known mitochondrial KATP channel opener, would protect against chronic doxorubicin cardiomyopathy both in vivo and in vitro.Male ICR mice were randomized to 1 of 4 treatments: saline, sildenafil (0.7 mg/kg IP), doxorubicin (5 mg/kg IP), and sildenafil (0.7 mg/kg IP)+doxorubicin. Apoptosis was determined using the terminal deoxynucleotidyl transferase mediated dUTP nick-end labeling and in situ oligo ligation methods. Desmin distribution was determined via immunofluorescence. Bcl-2 was analyzed by …

The survey instrument used was the National College Health Assessment. Variables were categorized as demographic, alcohol perception, and alcohol …

Synthesis And Characterization Of Methylene Bis (P-Cyclohexyl Isocyanate)-Poly (Tetramethyl Oxide) Based Polyurethane Elastomers, Kennard Marcellus Brunson

Theses and Dissertations

This research concerns the development and characterization of methylene bis (p-cyclohexyl isocyanate/butanediol) (HMDI/BD) based polyurethanes used in connection with surface-active anti-microbial polyurethanes. Previously studied polyurethanes having an isophorone diisocyanate/butanediol (IPDI/BD) hard block contaminated water during dynamic contact angle (DCA) analyses. This contamination by unknown species confounds results from biocidal studies and jeopardizes the use of the polyurethane as a matrix polyurethane. By contrast, polyurethanes with methylene bis (p-cyclohexyl isocyanate)/butanediol hard block showed no contamination during DCA analysis. For this reason, further study of HMDI/BD/PTMO polyurethanes was conducted. HMDI/BD polyurethanes were synthesized with 15-50wt% hard block and a soft block of …

Magic Mountain, Diana Al-Hadid

Theses and Dissertations

My installations are propositions for an imaginary world that relies on its own internal logic, a world of believability without recognition. While the work references landscape it also emphasizes its contrivance, as it is automatically estranged in an "unnatural" gallery setting. I subvert or de-familiarize the materials and processes that I use in the service of creating a fictitious environment. My places are impossible places. They are irregular, illogical, and unstable. Our imagination can be one of most dangerous things to psychological stability as it is an inventory of all things possible, no matter how irrational or improbable. The irrational …

Objects And Images, Mary Bergshneider Magneson

Theses and Dissertations

I create to emphasize the aesthetic or beauty of an object. When I begin a work, I feel the influence of the many photos I am constantly looking at and analyzing. I look at how light affects color, how light defines form, and how patterns are created by repeated shapes. I try to reproduce the things I see, but with dramatic impact by enlarging shapes and emphasizing colors. While my paintings are about pure aesthetics, my books are social commentary.

Modulation Of Gene Expression By Tumor-Derived Mutant P53. Role Of Transactivation In Gain-Of-Function., Mariano J. Scian

Theses and Dissertations

It was hypothesized that the C-terminal sequences for mutant p53 would be required for oligomerization. and oligomerization may be critical for gain-of-function. An N-terminal deletion mutant of p53 that deletes amino acids 1-293 was used as a tool to perform hetero-oligomerization studies. This mutant retains the entire oligomerization domain but dispenses off the transactivation domain and a large portion of the sequence- specific DNA-binding domain. Co-transfection experiments show that p53 del. 1-293 forms hetero-oligomeric complexes with p53-D281G. Also. co-expression of p53 del. 1- 293 with p53-D281G inhibited p53-D28lG-mediated transactivation of the EGFR and MDRl promoters suggesting that hetero-oligomerization inactivates transcriptional …

Long-Term Cardioprotection With Phosphodiesterase-5 Inhibition Against Ischemia-Reperfusion Injury: Role Of Nitric Oxide., Vladimir Paul Daoud

Theses and Dissertations

Recent studies have shown that the potent phosphodiesterase-5 (PDE-5) inhibitor, sildenafil citrate, induces a powerful cardioprotective effect against ischemia-reperfusion (I/R) injury in rabbit and mouse hearts. However, the effect of this drug in inducing long-term protection against I/R injury remains unknown. The goal of this study was to identify the duration of the protective window of sildenafil citrate as well as vardenafil, a more potent PDE-5 inhibitor. Rabbits were treated with sildenafil (0.7 mg/kg, iv), vardenafil (0.143 mg/kg), or an equivalent volume of saline. After 24 hrs, 48 hrs, 96 hrs, or 7 days of sildenafil treatment, the hearts were …

The Need, Feasibility, And Means Of Establishing A Speech Center, Julie Carter Irvin

Theses and Dissertations

According to Tom Shachtman, "the speech of too few people achieves eloquence, and that of the vast majority does not even reach a tolerable level of articulate behavior" (5). Articulate behavior has not always been a rare characteristic; from antiquity through the mid-twentieth century, the study of rhetoric was privileged and considered necessary for a well-rounded education. If today's society is inarticulate, then how can eloquence and articulateness be reintroduced as staples of a successful person in today's society? The answer is easy - through the study of rhetoric. After examining the study of rhetoric from antiquity to the present, …

The Extraction Of Type Ii Collagen And The Electrospinning Of Nano-Fibrous Scaffolds, Danielle Careen Knapp

Theses and Dissertations

Articular cartilage lining joints, such as in the knee, functions to reduce friction and absorb shock. Collagen type II is the largest constituent in the extracellular matrix of articular cartilage and its restoration is of the highest interest to tissue engineers. Cartilage has little ability to naturally regenerate due to the absence of vascularity and the inability of the chondrocytes to proliferate at a high rate. It would be ideal to create a mimicking extracellular matrix/scaffold from type II collagen that could possibly be used to replace damaged articular cartilage that has the same function and morphology. Three different groups …

Codes Of Interaction, Timothy Michael Martin

Theses and Dissertations

The ideas within this thesis are meant to clarify my explorations, research and painting practice during my studies at Virginia Commonwealth University. I expand on my general statements about being fascinated by advancing technologies and concerned about the after effects of these advancements. The writing explores my curiosity about the internal, skeletal structure of things and how they operate. I explain how the paintings are idiosyncratic hybrids that evoke animation, imaginary scientific propositions, blueprints, maps, and advancing technologies. The work combines these interests with my observations of day-to-day experiences. Isolated events provide found compositions which I then manipulate: a seemingly …

Evidence For Absence Of Latchbridge Formation In Phasic Saphenous Artery, Shaojie Han

Theses and Dissertations

Tonic arterial smooth muscle can produce strong contractions indefinitely by formation of slowly cycling crossbridges (latchbridges) that maintain force at a high energy economy. To fully understand the uniqueness of mechanisms regulating tonic arterial contraction, comparisons have been made to phasic visceral smooth muscles that do not sustain high forces. This study explored mechanisms of force maintenance in a phasic artery by comparing KCl-induced contractions in the tonic, femoral artery (FA) and its primary branch, the phasic saphenous artery (SA). KCl rapidly (5 N/m2) and [ca2+]i (250 nM) in FA and SA. By 10 min, [ca2+]i declined to 175 nM …

Integration Of Vmc++ Into A Commercial Treatment Planning System, Joseph Kingsley Gardner

Theses and Dissertations

Recently, there has been interest to integrate VMC++ into the commercial treatment planning system at VCU as another Monte Carlo code option, since it has been shown to increase efficiency dramatically without introducing a significant amount of systematic error. Also, independent validation of VMC++ for photon beams is of interest since this has not been performed previously in literature. This study included several tests required to integrate VMC++. Output factor normalization was performed and found to agree with experiment to within 1% for all field sizes except 1x1 cm2. Geometric validation was successful. Dosimetric validation was performed with respect to …

Country Views, Rebecca Massie

Theses and Dissertations

Over the years I have created many different images and explored a variety of media along my artistic journey. Similar images continue to occur in my work - images from my life as a child and as an adult in rural settings. I lived on a poultry farm and was involved in working with my parents there. When I married, my husband was a cattle farmer so I continued to live on a farm and use rural images in my work. Living in the country makes me constantly aware of the relationship between God, nature and man. I believe that …

Innovative Interventions For Disordered Eating: A Pilot Comparison Between Dissonance-Based And Yoga Interventions, Karen S. Mitchell

Theses and Dissertations

Disordered eating, including bingeing, dieting, purging, and clinical and subclinical forms of anorexia nervosa, bulimia nervosa, and binge eating disorder, is prevalent among college-aged women. To date, few interventions have successfully reduced risk factors related to disordered eating. One promising intervention utilizes principles of cognitive dissonance to reduce thin-ideal internalization among women at risk for eating disorders. Additionally, the benefits of yoga, including increased awareness of bodily processes, offer hope that this practice might reduce disordered eating symptomatology. The current study compared cognitive dissonance and yoga interventions for disordered eating attitudes and behaviors. Hierarchical regression analyses revealed that there were …

The Marinhieros Project: Roseneath Rd & Patterson Ave, Jacqueline H. Crowley

Theses and Dissertations

In questioning the very nature of a thing, at its most basic level, a new assessment can be made of what the thing in question truly is. When we ask ourselves, what is a weed, we begin to pull the word apart - to decrypt the word from the cultural baggage that has collected around it over the course of the history of language.The cultural connotations of 'weed' cling to it like barnacles, removing the word from its true value. We reevaluate meaning, chronicling all the possible constructions of a word, all the possible varieties, where it came from, what …

Complementary And Alternative Medicine And Diet Change In Southern Rural Residents Enrolled In A Cancer Prevention Intervention Trial, Amanda Kracen

Theses and Dissertations

Using data from The Rural Physician Cancer Prevention Project, a dietary intervention trial, this cross-sectional, longitudinal study explored predictors of complementary and alternative medicine (CAM) use in a Southern, rural population (N = 375). Participants' dietary knowledge, stage of change, and dietary behavior were examined at baseline and 1 and 12 months after the intervention. More than half the participants (mean age = 48 years; 60% female; 60% Caucasian) reported using CAM. Logistic regression indicated that age, education, ethnicity and trust in physician affect the likelihood of CAM use. Hierarchical multiple regressions suggested that CAM use was associated with healthier …

Memories We Forget, Michael Dax Iacovone

Theses and Dissertations

I have always preferred the journey to the destination. When I was growing up, my family drove back and forth between Florida and New York every summer. My father did the driving, my mother sat next to him, and my older brother and sister sat in the back seat. This left the cavernous back of the family station wagon for me and the luggage. There was no radio, very little conversation, and I didn't sleep. I spent these summer trips staring for endless hours, out of the back window of the car, transfixed on the expanse of open road behind …
