Baltodano, Michael C. Coronado, Nicholas Elmer, Theresa K. Webster, Huaqing Zhao, Xiaoning Lu, Sthefano Araya, Sameer Patel

Student Papers, Posters & Projects

Background: Although postoperative complications of paramedian forehead flap (PMFF) are generally low, surgical site complications and unplanned reoperation can still occur. Recent literature suggests infection to be the most common complication following PMFF reconstruction. This study sought to determine the patient and preoperative factors associated with surgical site complications and unplanned reoperations at a national level.

Methods: Patients who underwent PMFF reconstruction from the ACS-NSQIP 2007 - 2019 database were analyzed to determine composite surgical site morbidity and unplanned return to the operating room. Patient and operative factors were also analyzed to assess independent risk factors for surgical site morbidity …

All Peer-Reviewed Publications

Food insecurity continues to affect more than two-thirds of the population in sub‐Saharan Africa (SSA), particularly those depending on rain-fed agriculture. Striga, a parasitic weed, has caused yield losses of cereal crops, immensely affecting smallholder farmers in SSA. Although earlier studies have established that Striga is a constraint to crop production, there is little information on the spatial extent of spread and infestation severity of the weed in some SSA countries like Malawi and Zambia. This study aimed to use remotely sensed vegetation phenological (n = 11), climatic (n = 3), and soil (n = 4) variables to develop a …

Essential Property, Timothy M. Mulvaney, Joseph William Singer

Faculty Scholarship

For a sizable swath of the U.S. population, incomes and wealth are insufficient to cover life’s most basic necessities even in the most ordinary of times. A disturbingly resilient explanation for this state of affairs rests on the view that resource inequities are avoidable through self-reliance, a stance that invites observers to see people in poverty as morally suspect. This Article advances a counterview in contending that the widespread lack of essential resources did not simply arise naturally via individuals’ life choices but instead has been, in very meaningful part, created and perpetuated by our system of property laws.

Designing For Justice: Pandemic Lessons For Criminal Courts, Cynthia Alkon

Faculty Scholarship

March 2020 brought an unprecedented crisis to the United States: COVID-19. In a two-week period, criminal courts across the country closed. But, that is where the uniformity ended. Criminal courts did not have a clear process to decide how to conduct necessary business. As a result, criminal courts across the country took different approaches to deciding how to continue necessary operations and in doing so many did not consider the impact on justice of the operational changes that were made to manage the COVID-19 crisis. One key problem was that many courts did not use inclusive processes and include all …

The most significant changes to the UCC consist of a new Article 12 dealing with digital assets and amendments to Article 9 that facilitate the leveraging of these assets. Also in 2019, …

The Private Law Of Stablecoins, Kara J. Bruce, Christopher K. Odinet, Andrea Tosato

Faculty Scholarship

Stablecoins are one of the cornerstones of the crypto world. They’ve attracted significant attention over the past few years, ranging from Wall Street to kitchen table investors, and even the White House. As a less volatile alternative to crypto-assets like bitcoin, stablecoins have the potential to change the way we make payments, unlock the groundwork needed for more blockchain-based applications, and even reorient the economy toward private money. But how stable are these stablecoins, really? Can they be relied upon in the way their many proponents claim? And how much of the popular beliefs about stablecoins match their realities? That’s …

Characterization Of Colletotrichum Nymphaeae Isolates From Apple With Reduced Sensitivity To Fluazinam And Tebuconazole, Rulyu Meng

All Theses

Apple bitter rot is caused by Colletotrichum nymphaeae and other Colletotrichum species and management relies primarily on synthetic pesticides. Very few fungicides are effective against the disease and resistance has further limited their usefulness. A recent study indicated relatively low EC₅₀ values (the concentration required to inhibit 50% of mycelial growth in vitro) of C. nymphaeae isolates from Brazilian apples to fluazinam and tebuconazole, two fungicides that are not routinely used for bitter rot control. Isolates on opposite sides of the sensitivity range were designated either sensitive (lowest EC₅₀ values) and reduced-sensitive (highest EC₅₀ values). The objective …

Designing The House Of The Future: Social Commentary On Retrofuturism, Alyssa Woodruff

All Theses

This project explores the aesthetics of retrofuturism and the historical context of the house of the future. Retrofuturism captures how people perceived the future during previous eras in history. Conceptions of the future reflect the time period in which they are created. I designed and implemented a 3D model of a house of the future to express the aesthetics of mid-century modernism. I created the models in ZBrush and Maya. I took inspiration from The Jetsons cartoon, the New York World’s Fair of 1964-65, and Disneyland’s original Tomorrowland theme park. This project also incorporates contemporary features to reflect modern concerns. …

Strangers Switching Their Identities: Cultural Identity Management And Performance On Social Media A Qualitative Analysis Of International Students’ Intercultural (Ex)Change Processes And Perceptions Regarding Their Stay In The United States And Countries Of Origin, Vivian Kretzschmar

All Theses

In this globalized world, cross-country travel for education has been a prevalent (5.6 million students identified as international students in 2020) and ever-increasing (with a predicted increase of 250% by 2030) trend through the past decades. The sojourn impacts the students’ experience of the new culture and the ensuing shocks and adaptations. The understanding of something as complicated as culture, trying to be integrated into a new culture, and its perception to individuals, of course, have their ways of distinct communication trends through social media.

The struggle of maintaining and changing one’s cultural identity and adaptation across cultures has been …

Unmanned Ground Vehicle Proximal Sensing For Forage Biomass Production Estimations, Curtis Erwin

All Theses

A large increase in productivity could be realized by small increases in efficiency and utilization on grasslands due to their large area. Pre-harvest biomass estimations can help forage producers make better informed management decisions. Producers of dry hay and hay silage can better identify plant growth stages and the optimal time to harvest. Grazers can better determine the most efficient number of animals and stocking density. The goal of this study was to create a novel pre-harvest biomass estimation method utilizing compressed height combined with an unmanned ground vehicle (UGV). A compression plate named a “compression ski” was constructed and …

Venomic Characterization Of A Medically Relevant Rear-Fanged Snake, Conophis Lineatus (Dipsadidae: Xenodontinae), From Middle America, Tristan Schramer

All Theses

Most traditional research on snake venoms has focused on front-fanged snake families (Viperidae, Elapidae, and Atractaspididae). However, venom is now generally accepted as being a much more broadly possessed trait within snakes, including species traditionally considered harmless. Unfortunately, due to historical inertia and methodological challenges, the toxin repertoires of non-front-fanged snake families (e.g., Colubridae, Dipsadidae, and Natricidae) have been heavily neglected despite the knowledge of numerous species capable of inflicting medically relevant envenomations. Integrating proteomic data for validation, we perform a de novo assembly and analysis of the Duvernoy’s venom gland transcriptome of the Central American Road Guarder (Dipsadidae: Xenodontinae: …

Multiple Objective Function Optimization And Trade Space Analysis, Yifan Xu

All Theses

Optimization can assist in obtaining the best possible solution to a design problem by varying related variables under given constraints. It can be applied in many practical applications, including engineering, during the design process. The design time can be further reduced by the application of automated optimization methods. Since the required resource and desired benefit can be translated to a function of variables, optimization can be viewed as the process of finding the variable values to reach the function maxima or minima. A Multiple Objective Optimization (MOO) problem is when there is more than one desired function that needs to …

Investigating Attention Modeling Differences Between Older And Younger Drivers, Kathryn Baringer

All Theses

As in-vehicle technologies (IVTs) grow in both popularity and complexity, the question of whether these IVTs improve, or hinder, driver performance has gained more attention. The ability to predict when a driver will be looking at the road or a display on the car’s dashboard or center console is crucial to understanding the impact of the recent tech-heavy trend in car designs on safety and the extent to which IVTs compete with the primary driving task for visual resources. The SEEV model of visual attention has been shown to be able to predict the probability of attending an area if …

Cover Cropping And Organic Amendments To Improve Sandy Soils Under Organic Vegetable Production, Charles Williamson

All Theses

Coastal Plain soils in the Southeastern USA are typically sandy with poor soil structure, low soil organic carbon (SOC) content, and meager soil fertility that pose challenges to organic agriculture. Adding organic inputs is a strategy to improve these soils' physical, chemical, and biological characteristics. Here, we aim to investigate the impacts of Cover Cropping (CC) and manure inclusions on sandy soils under organic vegetable production. The experiment design was a randomized complete block with two treatments of manure application (with and without) and four CC treatments of cereal rye (Secale cereale), hairy vetch (Vicia villosa), …

Utilizing Systematic Design And Shape Memory Alloys To Enhance Actuation Of Modular High-Frequency Origami Robots, Jessica M. Den Haese

All Theses

Shape memory alloys (SMAs) describe a group of smart metallic materials that can be deformed by external magnetic, thermal, or mechanical influence and then returned to a predetermined shape through the cycling of temperature or stress. They have several advantages, such as having excellent mechanical properties, being low cost, and being easily manufactured, while also providing a compact size, completely silent operation, high work density, and requiring less maintenance over time. SMAs can undergo sold-to-solid phase transformations, and it is because of these phase transformations that they can experience shape memory effect (SME); or the ability to recover from a …

Flexural Testing Of Precast Reinforced Concrete Bridge Slabs, Evaluation Of Deterioration And Strengthening Applications, Alyssa Leaman

All Theses

This thesis investigates the strength of flat precast concrete slabs that were taken from decommissioned South Carolina bridges. The specimens tested spanned 14 ft (4.3 m) or 15 ft (4.6 m), were 5 ft (1.5 m) or 5.5 ft (1.7 m) wide, and 8.25 in (210 mm) thick. In South Carolina, there are approximately 3000 similar bridges that use these slab members. Testing was conducted to determine the flexural capacity of “typical” slabs and the residual strength of slabs having visible deterioration of both the rebar and the concrete. For the slabs that were load rated below the new standards, …

Examining The Perceptions Associated With Sunday Hunting Restrictions In South Carolina, Elizabeth Piller

All Theses

Public land is an invitation for many to engage with the natural world through a variety of different activities. Sometimes these activities are mutually exclusive and can cause land use conflict, which natural resource managers must navigate. One example of this conflict is restrictions to Sunday hunting. In South Carolina, Sunday hunting is allowed on private late but banned on public Wildlife Management Area (WMA) land. This regulation remains from ‘blue laws,’ laws prohibiting certain activities on Sundays to honor the Christian Sabbath (Balestra, 2008). Blue laws are typically thought of as prohibiting alcohol, but eleven U.S. states currently have …

Oam-Based Wavelets In A High Speed Optical Probing System For Measuring The Angular Decomposition Of The Environment, Justin Free

All Theses

This thesis presents the theoretical development of orbital angular momentum (OAM) based wavelets for the analysis of localized OAM information in space. An optical probing system for generating and detecting these wavelets is demonstrated; individual wavelets can scan the environment in 10µs or less. The probing system was applied to a three-dimensional atmospheric turbulence distribution to obtain a continuous wavelet transform of the angular information of the turbulent propagation path about a fixed radius. An entire continuous wavelet transform was measured in 3.8ms; the measurements are much faster than the turbulence and give insight into the short time scale of …

Patterns Of Occurrence Of The Black Basses In The Upper Savannah River Tributaries Of Georgia And South Carolina With Emphasis On Bartram’S Bass Micropterus Sp. Cf. Coosae, Caroline Cox

All Theses

Aquatic ecosystems are among the most threatened in the world due to anthropogenic alterations to the natural landscape and native biotas. Identifying the local and landscape-level environmental factors that influence the occurrence of endemic species can help protect aquatic ecosystems by facilitating predictions of where hybridization or replacement with generalist species may occur across the landscape. The need for such predictions is pronounced for black bass species in the southeastern United States. Bartram’s Bass (Micropterus sp. cf. coosae) is a provisional species of conservation concern. Allelic frequencies of Bartram’s Bass in Savannah River reservoirs and tributaries have been …

Chinese Celebrities’ Political Signaling On Weibo, Dan Chen, Gengsong Gao

Political Science Faculty Publications

In China, celebrities can dominate public discourse and shape popular culture, but they are under the state’s close gaze. Recent studies have revealed how the state disciplines and co-opts celebrities to promote patriotism, foster traditional values, and spread political propaganda. However, how do celebrities adapt to the changing political environment? Focusing on political signaling on Weibo, we analyze a novel dataset and find that the vast majority of top celebrities repost from official accounts of government agencies and state media outlets, though there are variations. Younger celebrities with more followers tend to repost from official accounts more. Celebrities from Taiwan …

Singlish Checker: A Tool For Understanding And Analysing An English Creole Language, Lee-Hsun Hsieh, Nam Chew Chua, Agus Trisnajaya Kwee, Pei-Chi Lo, Yang-Yin Lee, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

As English is a widely used language in many countries of different cultures, variants of English also known as English creoles have also been created. Singlish is one such English creole used by people in Singapore. Nevertheless, unlike English, Singlish is not taught in schools nor encouraged to be used in formal communications. Hence, it remains to be a low resource language with a lack of up-to-date Singlish word dictionary and computational tools to analyse the language. In this paper, we therefore propose Singlish Checker, a tool that is able to help detecting Singlish text, Singlish words and phrases. To …

Appearance-Preserved Portrait-To-Anime Translation Via Proxy-Guided Domain Adaptation, Wenpeng Xiao, Cheng Xu, Jiajie Mai, Xuemiao Xu, Yue Li, Chengze Li, Xueting Liu, Shengfeng He

Research Collection School Of Computing and Information Systems

Converting a human portrait to anime style is a desirable but challenging problem. Existing methods fail to resolve this problem due to the large inherent gap between two domains that cannot be overcome by a simple direct mapping. For this reason, these methods struggle to preserve the appearance features in the original photo. In this paper, we discover an intermediate domain, the coser portrait (portraits of humans costuming as anime characters), that helps bridge this gap. It alleviates the learning ambiguity and loosens the mapping difficulty in a progressive manner. Specifically, we start from learning the mapping between coser and …
