Visual Argument Reconsidered: 'Objective' Theory And A Classical Rhetorical Approach, Daniel Richards May 2009

Visual Argument Reconsidered: 'Objective' Theory And A Classical Rhetorical Approach, Daniel Richards

All Theses

Visual argument is a relatively new discipline within the field of visual rhetorics. Consequently, visual rhetoricians have presented new theories of visual argumentation without fully considering the possibilities of existing textual methodologies as explanatory tools—especially classical rhetorical devices. This thesis presents a methodology for examining and creating visual arguments based on the concepts of topoi and figures of speech. I contend that these classical rhetorical devises embody an “objective” understanding of visual communication that shows one way of bridging the empiricism/rationalism debate in epistemology. By demonstrating that knowledge comes from the necessary interplay of perception and conception, I attempt to …

Managing Linepithema Humile (Mayr), The Argentine Ant, In South Carolina State Park Campgrounds, Brittany Ellis May 2009

Managing Linepithema Humile (Mayr), The Argentine Ant, In South Carolina State Park Campgrounds, Brittany Ellis

All Theses

Linepithema humile (Mayr), the Argentine ant, is known as a pest in many urban areas of the southeastern United States. In the Piedmont region of South Carolina, there is a documented problem with L. humile invading the campsites of state park campgrounds. While some parks have tried to implement proactive control programs, the most widely used tactic is spraying insecticides when L. humile populations become intolerable to visitors. Although park personnel are treating problem areas with liquid insecticide, park visitors also treat their campsites with insecticidal products, as well as products not labeled for ant control.
Surveys in 2008 showed …

Victims And Aggressors: Black And Jewish Interethnic Relationships In Contemporary American Literature, Jessica Martin May 2009

Victims And Aggressors: Black And Jewish Interethnic Relationships In Contemporary American Literature, Jessica Martin

All Theses

Though blacks and Jews are often portrayed together in African-American and Jewish-American writing, the reasons for the juxtapositions are curious. Contemporary authors have created a close relationship between blacks and Jews that, perhaps with the exception of their cooperation during the Civil Rights movement, historically did not exist. But, the relationship between these two groups in literature offers a unique perspective on American racial and ethnic social structures because both blacks and Jews are considered minority groups, yet they also maintain a hierarchical relationship with one another. By employing black and Jewish characters, American writers, especially Jewish-American writers, create a …

Population Reconstruction Model To Analyze Harvest And Banding Data For Mourning Doves In South Carolina, Christopher Chumbley May 2009

Population Reconstruction Model To Analyze Harvest And Banding Data For Mourning Doves In South Carolina, Christopher Chumbley

All Theses

Mourning dove (Zenaida macroura) call count indices for South Carolina indicate a negative trend over the past 42 years (1.2% decline per year, p < 0.05). Total harvest estimates in the state increased from 2003-2007. Banding data from doves banded in South Carolina and data from annual examinations of harvested mourning dove wings during 2003-2007 were collected and analyzed. Data sets used contained 6,600 banded doves and 21,240 harvested dove wings. Survival estimates from band recovery analyses for adult and juvenile doves were 0.44 (± 0.04 SE) and 0.35 (± 0.06 SE), respectively. Survival rates were constant from year to year while recovery rates differed annually for adults and juveniles. The average natural mortality estimates for adults and juveniles in the presence of hunting were 0.45 ± 0.122 and 0.47 ± 0.189, respectively, during the study period. The average harvest and kill rates for adults and juveniles were also estimated. Age-at-harvest ratios adapted from annual wing examinations during the harvest were used with recovery rates to derive estimates of annual productivity in the population. Linear regression analysis of productivity estimates found a significant decline in productivity during 2003-2007 (-0.21, p < 0.10). The average productivity estimate was 1.43 (± 0.33 SE) juveniles per adult and the estimated productivity required to maintain a stable population was 1.60 (± 0.30 SE). The effects of constant survival rates, varying hunting mortality estimates and declining productivity estimates were discussed in relation to breeding populations in rural areas of South Carolina.

The Effect Of Hydrostatic Pressure On Bladder Smooth Muscle Cell Function, Margaret Drumm May 2009

The Effect Of Hydrostatic Pressure On Bladder Smooth Muscle Cell Function, Margaret Drumm

All Theses

Previous research has demonstrated that bladder smooth muscle cells (BSMC) respond to various forms of mechanical stimuli, including stretch and hydrostatic pressure, by increases of cell proliferation, activation of intracellular signaling pathways, and alteration of contractile and synthetic marker protein expression. These cellular/molecular level changes are all indicative of a BSMC phenotypic shift that can negatively impact the bladder function at the tissue and organ level. The objective of the present study is to test a hypothesis that bladder SMCs shift their phenotype from contractile to synthetic in response to elevated hydrostatic pressure. Rat bladder SMC cultures were exposed to …

A Pulsatile Bioreactor For Conditioning Tissue Engineered Heart Valves, Leslie Sierad May 2009

A Pulsatile Bioreactor For Conditioning Tissue Engineered Heart Valves, Leslie Sierad

All Theses

Tissue engineered constructs with autologous adult stem cells capable of self-repair and growth are highly desired replacements for diseased heart valves. However, the current approaches have inadequate mechanical properties to withstand in vivo implantation. Therefore, our group hypothesized that an in vitro environment of physiological intra-cardiac pressures and flow will stimulate stem cells to differentiate and remodel valvular scaffold constructs before implantation.
The group developed a pneumatic-driven conditioning system (Aim I) consisting of a three-chambered heart valve bioreactor, a pressurized compliance tank, a reservoir tank, one-way valves, pressure-retaining valves, and pressure transducers. The system can be sterilized using conventional autoclaving …

Ocular Vergence Response Over Anaglyphic Stereoscopic Videos, Brian Daugherty May 2009

Ocular Vergence Response Over Anaglyphic Stereoscopic Videos, Brian Daugherty

All Theses

The effect of anaglyphic stereographic stimuli on ocular vergence response is examined. An experiment is performed comparing ocular vergence response induced by anaglyphic stereographic display versus standard monoscopic display. Two visualization tools, synchronized three-dimensional scanpath playback and real-time dynamic heatmap generation,
are developed and used to subjectively support the quantitative analysis of ocular disparity. The results of a one-way ANOVA indicate that there is a highly significant effect of anaglyphic stereoscopic display on ocular vergence for a majority of subjects although consistency of vergence response is difficult to predict.

Hi Honey I'M Home, Clarke Stuart Curtis May 2009

Hi Honey I'M Home, Clarke Stuart Curtis

All Theses

My work is generated from an internal struggle which arises from the transition of my youth to my adulthood. Through my experiences, I have come to believe that there is a significant deficit in what signifies the transition to adulthood in contemporary society. I view that our contemporary rites of passage differ greatly from historical cultures and wish to conjoin the two with my personal mythology and through contemporary and pop culture to possibly shed light on my seeming sense of arrested development. I am interested in depicting my own fantastical rites as if I lived in both cultures overcoming …

Contracting In The Pharmaceutical Industry: Predicting Payments In Strategic Alliances, Jonathan Altman

All Dissertations

ABSTRACT
This paper empirically analyzes how circumstances affect the creation of strategic alliances in the pharmaceutical industry, and the form these alliances take. The models introduced in this paper use the cost of capital and monitoring costs to predict the timing of the deal, which in turn allows the prediction of the deal type. The deal type is then used to predict payment types used in the deal. Deals are characterized by five payment types; upfront, royalty, milestone, equity, and research payments. Deals are also characterized by one of five deal types; co-development, license, acquisition, outsource, and asset purchase. Each …

The Effects Of Wastewater Effluent On A Fish And Amphibian Species, Anthony Sowers May 2009

The Effects Of Wastewater Effluent On A Fish And Amphibian Species, Anthony Sowers

All Dissertations

Wastewater effluents have been shown to contain a variety of anthropogenic compounds, many of which have endocrine-disrupting properties. While multiple laboratory studies have shown the effects of such compounds on an individual basis at elevated concentrations, little research has attempted to characterize the effects of exposure to environmentally relevant mixtures of endocrine disruptors. The current study examined the effects of long-term exposure to graded concentrations of wastewater effluent on the fathead minnow, Pimephales promelas, and the northern leopard frog, Rana pipiens. Fathead minnows were exposed from the larval stage through sexual maturity, while northern leopard frogs were exposed as eggs …

Recovery Of Fathead Minnows (Pimephales Promelas) Following Episodic Copper Exposure: A Biochemical, Physiological, Individual, And Population Perspective, Holly Zahner May 2009

Recovery Of Fathead Minnows (Pimephales Promelas) Following Episodic Copper Exposure: A Biochemical, Physiological, Individual, And Population Perspective, Holly Zahner

All Dissertations

The US EPA utilizes the Biotic Ligand Model (BLM) when developing site-specific water-quality criteria for copper. The BLM was calibrated using toxicity data from fixed duration continuous exposures (48 or 96h LC50). However, exposures of copper in natural aquatic systems typically vary in concentration, duration, and may occur multiple times over the life-span of an organism. Additionally, organisms will experience periods in copper free water, potentially allowing them to detoxify and recover homeostasis. Yet, the BLM framework does not consider brief exposures (<24h), multiple exposures, latent responses, or organism recovery, potentially resulting in an inaccurate assessment of exposure toxicity. A recently proposed physiologically-based addition to the BLM will extend the applicability of the framework to brief, multiple pulse copper exposures. Thus, the overall goal of this research was to characterize the recovery of larval Pimephales promelas following episodic copper exposure at a biochemical, physiological, individual, and population level.
The response of whole-body sodium, whole-body Na+/K+-ATPase, and whole-body carbonic anhydrase in larval P. promleas was quantified …

Comparative Morphological And Functional Analysis Of Wing Coupling And Related Structures In Caddisflies (Insecta: Trichoptera), Ian Stocks May 2009

Comparative Morphological And Functional Analysis Of Wing Coupling And Related Structures In Caddisflies (Insecta: Trichoptera), Ian Stocks

All Dissertations

Several orders of morphologically four-winged insects have evolved mechanisms that enforce a union between the mesothoracic and metathoracic wings (forewings and hindwings) during the wing beat cycle. Such mechanisms result in a morphologically tetrapterous insect flying as if it were functionally dipterous, and these mechanisms have been described for several insect orders. The caddisfly suborders Annulipalpia and Integripalpia (Trichoptera) have each evolved wing coupling apparati. At least three systems have evolved within the suborder Annulipalpia (Polycentropodidae; Hydropsychidae: Hydropsychinae, Macronematinae), and within Integripalpia the evolution of wing coupling mechanisms is diverse to the point that it defies simple enumeration into discrete …

Application Of Microsatellite/Ssr Markers For The Identification Of Peach Rootstocks And Chromosomal Regions Associated With The Response To Peach Tree Short Life Syndrome, Xiaoyu Liu

All Dissertations

Peach Tree Short Life (PTSL) is a complicated disease syndrome involving nematodes, temperature, soil conditions, pruning and secondary pathogens. The disease occurs commonly in the southeastern U.S., and possibly in other areas of the U.S., Europe, South America and South Africa as the related Bacterial Canker Complex. PTSL causes premature tree death during the 3rd or 4th year after planting, resulting in large economic losses for growers. Recently, Guardian® &lsquo BY520-9&rsquo rootstock was selected for its tolerance to PTSL; however, the genetic basis for this tolerance remains unknown.
Nemaguard, a PTSL susceptible rootstock, and Guardian® selection 3-17-7 were crossed. Each …

Metabolic Tracer Studies Of Linoleic And Linolenic Acids To Identify Biohydrogenation Intermediates Produced By Ruminal Microorganisms, Yong-Jae Lee May 2009

Metabolic Tracer Studies Of Linoleic And Linolenic Acids To Identify Biohydrogenation Intermediates Produced By Ruminal Microorganisms, Yong-Jae Lee

All Dissertations

Conjugated linoleic acids (CLA) have been shown to regulate many physiological functions affecting human health. These CLA can endogenously originate from trans fatty acids through the enzymatic activity of desaturase, or they are produced from dietary polyunsaturated fatty acids via the biohydrogenation process in the rumen. A minimum of seventeen CLA isomers have been identified in the intestinal contents of ruminants; however, the entire synthetic pathway for all isomers is not known. The objective of this study was to establish the number and identity of intermediates including CLA that originate from linoleic and linolenic acid biohydrogenation. To accomplish this objective, …

We’Re Here, We’Re Hopeful, And We Can Do Well: Conceptions And Attributes Of Positive Youth Development Among Immigrant Youth, Yulika Forman, Dan Du, Megan Kiely, Jennifer Carrano

Journal of Youth Development

Using qualitative and quantitative information from Grades 8 and 9 of the 4-H Study of Positive Youth Development (PYD), we describe the conceptions of thriving youth present within adolescent immigrants to the United States, and interrelate these conceptions with quantitative scores for PYD, contribution, and positive future orientation. Conceptions of thriving that included positive future orientation were associated with higher quantitative scores for PYD and Contribution. Conceiving of thriving as making contributions to themselves or their communities was associated with higher quantitative scores for Contribution. These findings suggest that immigrant youth whose qualitative definitions of thriving include the U.S.-based conceptions …
