Sustenance, Brenton Pafford

All Theses

Utilizing the ceramic process I create objects that facilitate experiences in the domestic space. Developing sculptural elements that evoke memory traces, and in heightening the everyday to an aesthetic, I place value on the overlooked, under-thought items that sustain existence. 'It is the realm of these submerged memory-traces that creative art moves, bringing them into the orbit of everyday life and making them available to the experience of others by formalizing and projecting them onto elements of the familiar world which can receive and transmit them.' - Rawson The objects I created for this exhibition are rooted in memory traces, …

The Effects Of Conjugated Linoleic Acid Supplementation On Lipopolysaccharide-Challenged Synoviocytes, Allison Millican

All Theses

Osteoarthritis is one of the leading causes of lameness in the athletic horse. Cases of equine osteoarthritis typically present with synovitis, or inflammation of the synovium. This inflammation in the synovium leads to the production of inflammatory cytokines and eicosanoids. Although these downstream products can be beneficial, overproduction can lead to degradation of cartilage and joint disease. Opportunities to help mitigate or decrease inflammation within the joint are of current interest to the equine industry. One method being investigated is nutritional supplementation. The anti-inflammatory effects demonstrated by CLA supplementation make it a potential prospect for utilization in mitigating joint inflammation. …

Associations Between Travel Behavior And The Academic Performance Of University Students, Qianying Wu

All Theses

Purpose: Different travel behavior, particularly the choice of commuting modes, will have different impacts on students. On one hand, it has been suggested that active commuting (walking, cycling, and taking transit) will add routine daily exercise. Moreover, health benefits (improved cognitive function and reduced anxiety) from physical activity might increase students' academic performance. Nevertheless, too much physical activity may reduce the time for students to study. Travel time may shorten study time, and study time has been identified as positively contributing to academic performance. Considering that there is limited research examining travel behavior and academic achievement of university students, this …

A Device To Record Naturally Daily Wrist Motion, Surya Sharma

All Theses

We introduce a new device to record and store wrist motion activity data. The motivation to create this device was the fact that this data can be used to detect periods of eating or the number of bites consumed. There is no similar device available in the market. This device uses new components that have been recently introduced to the market, and newer techniques that can be used for low quantity production. The production cost for this device was $52, similar to other fitness trackers on the market. The device was capable of recording wrist motion activity for 24 hours …

Geotechnical Analysis Of The Foundation Of Fort Sumter National Monument Using Numerical Modeling, Daniel Kyser

All Theses

The foundational condition of the historical coastal fortification of Fort Sumter in Charleston, SC was analyzed though the use of numerical modeling. In this study, two-dimensional Finite Element (FE) analyses were conducted to assess the stability of the foundation-casemates-wall system in a coupled manner subjected to potential loadings such as ocean waves, storm surge and earthquake. The finite element model was verified by modeling the historical events (construction between 1820 and 1860, demolition due to artillery bombardment, reconstruction, earthquake, building of the Battery Huger, and the removal of fill from the parade ground) since the construction of the fort in …

Popular American News Media Explained Through Visual Arts: Using Drawing As A Tool For Humorous And Obligatory Cultural Critique, Joel Murray

All Theses

Through my drawings, I focus on jostling the passive American viewer out of her/his complacent acceptance of the images delivered by popular media outlets. Using humor as a multi-functional tool, I combine and reinterpret recognizable media artifacts to comment on the content that makes up American culture. This body of work is a cultural critique, pitting the ridiculous and superficial entertainment we (Americans) so easily ingest against current and crucial moments in time (i.e: political protests, violence, death, etc). Often times, the current media landscape is saturated with fast-cycling images and stories that do not promote careful contemplation. Instead, these …

A Model Of The Diurnal Variation In Lake Surface Temperature, Jonathan L. Hodges

All Theses

Satellite measurements of water surface temperature can benefit several environmental ap-plications such as predictions of lake evaporation, meteorological forecasts, and predictions of lake overturning events, among others. However, limitations on the temporal resolution of satellite mea-surements restrict these improvements. A model of the diurnal variation in lake surface temperature could potentially increase the effective temporal resolution of satellite measurements of surface tem-perature, thereby enhancing the utility of these measurements in the above applications. Herein, a one-dimensional transient thermal model of a lake is used in combination with surface tempera-ture measurements from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard the …

What Adds Up To Being: The Work Of Tanna Burchinal, Tanna L. Burchinal

All Theses

My practice takes form around embodied experience. I affect signifiers of the human body within the ordered grid, the scientific text, and the logic of the machine, to highlight the interdependencies of physical bodies and those social constructs that produce and influence identity. We are a part of these constructs that both extend and limit; we are enacting and interacting with them. I do not aim to eradicate these structures of power (without them, our identities are in chaos). Instead, I point out the pitfalls of these constructs that are perceived as unchanging, by making interaction and experience integral to …

How Copyright Law May Affect Pop Music Without Our Knowing It, Peter K. Yu

Faculty Scholarship

Commissioned for a symposium on copyright law and the creation of music, this article explores five questions about popular music that can be illuminated by greater insights into copyright law and the music business. Why do popular songs usually last for fewer than five minutes? Why are professional songwriters dissatisfied with Pandora and Spotify? Why can we bring European CDs back to the United States? Why can't YouTube videos be created with ASCAP/BMI licenses? Are digital downloads sales or licenses? And as a bonus: Why did the royalty rate for sheet music stay at seven cents per copy?

It is …

Sharing Stupid $H*T With Friends And Followers: The First Amendment Rights Of College Athletes To Use Social Media, Meg Penrose

Faculty Scholarship

This paper takes a closer look at the First Amendment rights of college athletes to access social media while simultaneously participating in intercollegiate athletics. The question posed is quite simple: can a coach or athletic department at a public university legally restrict a student-athlete's use of social media? If so, does the First Amendment provide any restraints on the type or length of restrictions that can be imposed? Thus far, neither question has been presented to a court for resolution. However, the answers are vital, as college coaches and athletic directors seek to regulate their athletes in a constitutional manner.

Relationship Between Peel Force, Opening Force, And Burst Force For A Semi-Rigid Cup And Lid, Pre- And Post-Retort, Raj Navalakha

All Theses

This research determines if there is any relationship between the peel force, the opening force and the burst force for a semi-rigid cup and lid system, for pre- and post-retort conditions. It also compares the relationship (regression lines) between these forces pre- and post-retort. These seal results were studied by varying the sealing parameters of dwell time and temperature while keeping the pressure constant. Polypropylene cups and a peelable barrier retort lidding were used in this study. As compared to past research, a different peel testing technique was used to measure the peel and the opening force. The entire lid …

Storm Water Damage Risk Assessment Along The South Carolina Heritage Trail, Charles Pellett

All Theses

This study was conducted to better predict and assess damage to high-value small-spatial scale landscapes from storm water. Storm water damage in the form of rill formation across the South Carolina Botanic Gardens (SCBG) Natural Heritage Garden Trail has been modelled as a function of contributing area using D8 and D-infinity flow direction algorithms on a preprocessed LiDAR-derived elevation raster. D8 and D-infinity algorithms were also applied over a set of stochastic Monte Carlo simulations (n=1,000) representing elevation error. The contributing area was calculated using each of the four methods for each 5'x5' cell along the trail. The output was …

Determining The Fate Of Non-O157 Shiga Toxin-Producing Escherichia Coli In Dairy Compost During Storage Using The Optimized Detection Method, Hongye Wang

All Theses

Shiga toxin-producing Escherichia coli (STEC), a member of Enterobacteriaceae family, has been recognized as emerging pathogens. Dairy compost is commonly applied to farmland as a soil amendment. Despite the agricultural benefit of manure-based soil amendment, the inadequately treated compost can contribute to fresh produce contamination on the farm. Moreover, the epidemiological results showed that the non-O157 STEC cases have surpassed those of E. coli O157. Therefore, it is critical to evaluate the behavior of non-O157 STEC strains in the dairy manure-based compost. The objectives of this study were to: 1) optimize a culturing method for detecting non-O157 STEC from dairy …

Characterization Of Biofilms On Medical Device Materials With Application To Reusable Surgical Instruments, Amanda Macaluso

All Theses

Reusable medical devices or reprocessed single-use devices are original medical devices that have been used once and then are cleaned, sterilized, and remanufactured for the purpose of an additional single use on a single patient [4]. Improperly reprocessed devices are a significant contributor to hospital-associated infections [4]. Challenges that hinder reprocessing are related to the complexity of reusable medical device design, the necessary validation of cleaning protocols required by the U.S Food and Drug Administration (FDA), the impact of human factors throughout the reprocessing cycle, as well as economic factors within new business models that are centered on reprocessing. Current …

Black Heart, Brandon Rashod Hodges

Theses and Dissertations

Identity is something that I believe we all struggle with at some point in our lives. Whether it is trying to find one's identity via place, culture, or response to power structure, the struggle to identify one's self seems to take precedence over anything else. Thus, identity is the main concern of this thesis. Moreover, while writing my thesis I have attempted to describe my journey towards discovering my identity, which includes being an agnostic born into a very religious family and society, identifying as a lover who struggles to define and understand love, defining my masculinity, especially my black …

Techniques, Technologies And Politics Of Crisis And Post-Crisis Economics: Anglo-American Macroeconomics And Alternatives, Jeffrey K. Hass

Sociology and Anthropology Faculty Publications

This paper attempts a critical appraisal of one core debate and theories in economics about the 2008 crisis and post-2008 economic growth and stagnation. In addition to examining formal publications, this essay also examines serious blogs by high-profile economists who are core participants in public discourse over economic policy. Drawing on the general logic of economic sociology and political economy — in particular, an appreciation for more complex microfoundations of economic practice (e.g. power and culture) and institutions—this paper addresses three issues about theoretical frameworks and claims about post-crisis growth or lack thereof: 1) Techniques: economists’ discourses focus primarily on …

The Limits Of Enumeration, Richard A. Primus

Articles

According to a well-known principle of constitutional interpretation here identified as the “internal-limits canon,” the powers of Congress must always be construed as authorizing less legislation than a general police power would. This Article argues that the internallimits canon is unsound. Whether the powers of Congress would in practice authorize any legislation that a police power would authorize is a matter of contingency: it depends on the relationship between the powers and the social world at a given time. There is no reason why, at a given time, the powers cannot turn out to authorize any legislation that a police …

A Study Of Surface Modification On Current Orthopaedic Bioceramics After In Vivo Exposure To The Physiological Environment, Alexander William Wusylko

All Theses

Over 300,000 total hip replacement (THR) surgeries are performed annually in the United States with generally good clinical outcomes. Surgical registries around the world report that approximately 90% of implanted THR devices survive for ten years or longer after implantation. However, the trend of increasing incidence of THR, particularly among younger, more active patients has generated considerable interest in THR design improvements to increase the longevity of these devices. As a result, many new articular bearing materials have been introduced for THR in recognition of prosthesis wear as a leading failure reason for contemporary designs. Ceramic-on-ceramic articulations were first introduced …

Microneedle Arrays For Injection Seeding Of Tissue Engineered Scaffolds, Katelyn Michelle Rye

All Theses

Tissue engineered constructs have proven to possess comparable mechanical and physical characteristics to autologous tissues making them suitable replacements fordiseased anatomy when autologous tissue transplants are unavailable. However, difficulty in reseeding the constructs with cells prevents the tissue-engineered scaffoldsfrom becoming an adequate, equivalent replacement for diseased tissues when compared to autologous transplants. Cells adhere to the outer surfaces of scaffolds but are incapable of penetrating the constructs to provide complete cellularization. If cells were able to populate the inner layers of the tissue, then they could likely diffuse into the intimal and external layers of the construct to create a …

The Hungry Games, Timothy Deters, Michael Garnaat, Isabel Gonzales, Megan Kupres, Evelyn Lugo, Ashley Munniksma, Jose Rivera, Nathan Spencer

LIB 322: Wicked Problems of Sustainability

Environmental activist and culture critic, Wendell Berry states in “The Pleasures of Eating,” “When food, in the minds of eaters, is no longer associated with farming and with the land, the eaters are suffering a kinds of cultural amnesia that is misleading and dangerous” (Berry 2) The obesity epidemic, mass hunger, the invasion of overly-processed and GMO-contaminated foods are just a few of the frightful consequences of our society’s overall disconnect with the food system. With so many obvious shortcomings, how does one even begin to tackle the wicked problem of food? According to several culture critics, including Michael Pollan, …
