The Puzzled Landscape, Amanda Musick
The Puzzled Landscape, Amanda Musick
All Theses
This series of work diverts landscape photography into object, material, and riddle. I investigate how we are conditioned to view and interact with the natural environment through constructing new, illusive vistas and forms using photographs I made in physical landscapes. Photographs that range from iconic views to details of rock textures are combined and altered to construct dioramas that represent forest, desert, ocean, and mountain landscapes. The dioramas are then photographed and deconstructed. Their remains are reorganized into piles and photographed as unrecognizable representations of the original place. The piles exist in a white, voided space portraying a sense of …
Job Insecurity Across Borders: An Examination Of Job Insecurity, Perceived Organizational Support, And Turnover Intentions In The United States And China, John Alexander Morgan
Job Insecurity Across Borders: An Examination Of Job Insecurity, Perceived Organizational Support, And Turnover Intentions In The United States And China, John Alexander Morgan
All Theses
Job insecurity is growing around the world, with employees staying at their jobs for shorter durations and part-time, contract, and even extremely short-term “gig” work becoming increasingly common. Job insecurity has been linked with several undesirable outcomes for both the individual and the organization, such as higher levels of employee burnout and increased turnover. This thesis seeks to extend the job insecurity literature by treating job insecurity as a demand within the Job Demands-Resources model, with perceived organizational support (POS) as its resource opposite. In addition, I utilized data collected in both the United States and China, providing insights into …
Asynchronous Propulsion Of The Three Sphere Micro-Swimmer Using Perturbed Magnetic Field, Arnab Mitra
Asynchronous Propulsion Of The Three Sphere Micro-Swimmer Using Perturbed Magnetic Field, Arnab Mitra
All Theses
In recent years much effort have been placed on development of microscale devices capable of propulsion in low Reynold number environment. These devices have potential in biomedicine, micro-fabrication and sensing fields. One of the most promising device that has been extensively studied is magnetic micro-swimmers. Due to small size of the swimmer they operate in low Reynolds number regime. In this case the hydrodynamics is governed by the viscosity rather than inertia. Since the swimmer is so small any kind of motor or other propulsion system is not feasible so we are using magnetic field to remotely control the swimmer. …
Analysis Of Frozen Desserts Using Low-Temperature Scanning Electron Microscopy (Lt-Sem), Kinsey Elizabeth Macdonald
Analysis Of Frozen Desserts Using Low-Temperature Scanning Electron Microscopy (Lt-Sem), Kinsey Elizabeth Macdonald
All Theses
Commercial vanilla ice cream and other frozen desserts from the United States were analyzed for ice crystal length using low-temperature scanning electron microscopy (LT-SEM). Average ice crystal length was determined using multiple micrographs of each sample/product. Out of the products tested, 11 out of 15 samples had an average ice crystal length above the consumer sensory threshold limit of 55 µm. Products containing stabilizers tended to have smaller average ice crystal lengths than products without stabilizers. With a few exceptions, lower fat products tended to have larger ice crystals because there was less fat to stabilize the ice crystals. Four …
Effect Of Strain Rate On The Tensile Behavior Of Cocrfeni And Cocrfemnni High Entropy Alloys, Mitra Shabanisamghabady
Effect Of Strain Rate On The Tensile Behavior Of Cocrfeni And Cocrfemnni High Entropy Alloys, Mitra Shabanisamghabady
All Theses
High entropy alloys (HEAs) are a new class of alloys with the potential to be used in critical load bearing applications instead of conventional alloys. The HEAs studied in this research were CoCrFeNi and CoCrFeMnNi. Both were single-phase face-centered cubic materials. The focus of this study was on the tensile behavior of the two materials at quasi-static and dynamic strain-rates (〖10〗^(-4) to 〖10〗^3 s^(-1)) and the underlying microstructural phenomena driving the behaviors. Electron back-scatter diffraction was performed on both HEAs to study the microstructure before mechanical testing. To study the effect of strain rate, tensile experiments were performed at quasi-static …
Investigation Of Fungi Causing Twig Blight Diseases On Peach Trees In South Carolina, Martha Jennie Hudgins Froelich
Investigation Of Fungi Causing Twig Blight Diseases On Peach Trees In South Carolina, Martha Jennie Hudgins Froelich
All Theses
In 2016, fungal pathogens causing twig blight disease were isolated from symptomatic one-year-old shoots from peach orchards in 6 locations in South Carolina. Four twig blight pathogens, which included Phomopsis amygdali, Botryosphaeria obtusa, Leucostoma persoonii, and Cytospora sp., were isolated. L. persoonii was isolated in the highest frequency, followed by P. amygdali and B. obtusa. All pathogens were sensitive to thiophanate-methyl (FRAC 1), pyraclostrobin, and azoxystrobin (both FRAC 11). However, they were not sensitive to boscalid and fluopyram (both FRAC 7). L. persoonii exhibited less sensitivity to difenoconazole and propiconazole (both FRAC 3) while P. amygdali and B. obtusa were …
Do Open Spaces Provide Refuge For Anurans Within An Urban Matrix?, David Ruple Hutto
Do Open Spaces Provide Refuge For Anurans Within An Urban Matrix?, David Ruple Hutto
All Theses
Urbanization is among the largest threats to amphibian populations through habitat fragmentation, isolation, and outright destruction. Urban open spaces, such as parks and golf courses, have the potential to provide amphibians with suitable habitat within an urbanized matrix. During the spring and summer of 2018, I conducted dip net surveys and active call surveys to determine the presence and abundance of anurans at 51 wetland sites within the Piedmont ecoregion of South Carolina. Nearly one-third of these wetlands were located within urban open spaces, while the others were situated along a rural – urban gradient. Impervious surface and road density …
Steroid Openflow Service Scalability Analysis, Khayam Anjam
Steroid Openflow Service Scalability Analysis, Khayam Anjam
All Theses
Modern cloud applications are hosted on data centers across vast geographical scopes and exchange large amounts of data continuously. Transmission Control Protocol (TCP) is the most popular protocol for reliable data transfer; however, due to TCP’s congestion control mechanism, maximum achievable throughput across a large bandwidth-delay product (BDP) network is limited. Various solutions exist to enhance data transfer throughput but they usually require non-trivial and explicit installation and tuning of specialized software on both sides which makes deployment limited. A software defined networking (SDN) based solution "Steroid OpenFlow Service (SOS)" was developed that utilizes multiple parallel TCP connections to transparently …
Effects Of Hydrological Management For Submersed Aquatic Vegetation Biomass And Invertebrate Biomass And Diversity In South Carolina Coastal Impoundments, Beau Anthony Bauer
Effects Of Hydrological Management For Submersed Aquatic Vegetation Biomass And Invertebrate Biomass And Diversity In South Carolina Coastal Impoundments, Beau Anthony Bauer
All Theses
Widgeongrass (Ruppia maritima) is a cosmopolitan submersed aquatic vegetation (SAV) of brackish wetlands. Management of SAV species is practiced in impounded tidal wetlands in coastal South Carolina to provide forage for waterfowl and other waterbirds. Widgeongrass also provides habitat and associated periphyton for aquatic invertebrates. I conducted an observational study to test effects of complete drawdown (CD) to dried substrate versus partial, shallow water (0–10 cm) drawdown (PD) during May–June 2016 on aquatic invertebrate and SAV biomasses and aquatic invertebrate diversity in managed brackish tidal impoundments (MTI) in the Ashepoo, Combahee, and Edisto Rivers Basin, South Carolina, because such …
An Investigation Of The Distribution And Behavior Of The Dark Rover Ant, Brachymyrmex Patagonicus Mayr, In South Carolina, David Quinn Bowers
An Investigation Of The Distribution And Behavior Of The Dark Rover Ant, Brachymyrmex Patagonicus Mayr, In South Carolina, David Quinn Bowers
All Theses
The dark rover ant, Brachymyrmex patagonicus Mayr, is a minute (~0.5 mm) dark brown or black formicine ant invasive from Argentina and Paraguay. In the southeastern United States, the dark rover ant is considered a nuisance pest, and is difficult to control. Recently, B. patagonicus has expanded its invasive range, especially in the southeastern United States. In South Carolina, this species has become more common in pest control accounts. Despite this, most of the biology and behavior of the dark rover ant remains unknown. The only official record of B. patagonicus in South Carolina is from 2010 in Horry County. …
Effects Of Surface Morphology On Ink Wetting And Adhesion On Polyolefin Blends, Ting Chen
Effects Of Surface Morphology On Ink Wetting And Adhesion On Polyolefin Blends, Ting Chen
All Theses
Compared to the conventional Ziegler-Natta (Z-N) catalysts, metallocene (m) catalysts have recently drawn more attention in the production of polyolefins, due to its better stereo-selectivity toward the polymer structures. To use metallocene catalyzed polyolefins as the print layers on the multilayer biaxial oriented polypropylene (BOPP) films, the effects of their topography, surface morphology and chemical compositions after corona treatment on the wetting and adhesion of water-based flexo inks were studied in this work. Seven blends containing different metallocene and Ziegler-Natta polyolefins, including polypropylene (PP), linear low polyethylene (LLDPE), and propylene random copolymer (EP), were extruded as the surface print layers …
Reproduction And Nest-Box Selection By Wood Ducks And Black-Bellied Whistling Ducks In Coastal South Carolina, Gillie Douglas Croft
Reproduction And Nest-Box Selection By Wood Ducks And Black-Bellied Whistling Ducks In Coastal South Carolina, Gillie Douglas Croft
All Theses
I conducted a landscape-scale survey of nest-structure use and production by wood ducks (Aix sponsa), black-bellied whistling ducks (Dendrocygna autumnalis), and hooded mergansers (Lophodytes cucullatus) across two riverine basins in coastal South Carolina during 2016–2017. For 364 and 354 nest boxes surveyed in each year (n = 718 box years), 61% were used by wood ducks, 15% by black-bellied whistling ducks, and < 1% by hooded mergansers. Across years, mean frequency of use of nest boxes by wood ducks and black-bellied whistling ducks did not differ between the Ashepoo, Combahee and Edisto Rivers (ACE) and Santee Rivers Delta and Winyah Bay (SRDW) Basins (F1,353 = 1.46, P = 0.2270, F1,353 = 1.48, P = 0.2247, respectively). Wood ducks nested from January–August (x̄ = 181-day nesting season, CV = 2.5%) with peak nesting in March–May. Black-bellied whistling ducks nested from May–September (x̄ = 116-day nesting season, CV = 8.6%) with peak nesting in June–July. Stepwise logistic, multiple regression revealed several correlations of physical and micro-habitat characteristics of nest boxes with their use by wood ducks and black-bellied whistling ducks. Wood ducks were 5.8% (β = −0.00006, P = 0.0035) more likely to select nest boxes for every 1,000 cm3 decrease in internal box volume. However, black-bellied whistling ducks were 19.6% (β = 0.00018, P < 0.0001) more likely to select nest boxes for every 1,000 cm3 increase in internal volume. Vegetative, canopy cover above boxes had a negative association with nest-box selection; boxes were 15.1% (β = −0.01642, P < 0.0001) and 11.1% (β = −0.01194, P = 0.0236) more likely to be selected by wood ducks and black-bellied whistling ducks for every 10% decrease in percent canopy cover. Additionally, nest boxes were 18.3% (β = 0.01677, P = 0.0053) and 9.8% (β = −0.01031, P = 0.0044) more likely to be selected by black-bellied whistling ducks for every 10 cm increase in distance from the base of boxes’ entrance vertically to ground or water surface and every 10 m decrease in distance between boxes. My data suggest the conventional nest box described by Bellrose (1980), with internal volume of 34,375 cm3 and internal dimensions of 25 × 25 × 55 cm, was usable for both species of ducks and therefore can be deployed where these species are sympatric. However, I suggest nest box entrances should have 12.7 cm diameters to facilitate use by larger black-bellied whistling ducks, as recommended by Bolen (1967a). Additionally, I observed both species of ducks selected boxes in open areas and often in ponds with predatory fish, which could create “ecological traps” for ducklings. I emphasize the importance of proper nest-box placement near suitable brood-rearing habitat (e.g., shoreline scrub-shrubs; Davis et al. 2007) to promote duckling survival and recruitment. For wood ducks, mean clutch size was 13 eggs, nest success was 65%, and hatching success was 49%. Based on egg-shell membranes found in nest boxes, mean number of wood duck ducklings exiting boxes did not vary between basins in 2016 (t1 = 1.04, P = 0.2966) and 2017 (t1 = 1.81, P = 0.0698). Pooled across years, an average of five wood duck ducklings exited structures. For black-bellied whistling ducks, mean clutch size was 11 eggs, nest success was 51%, and hatching success was 43%. Mean number of black-bellied whistling duck ducklings exiting boxes differed between basins in 2016 (t1 = 3.77, P = 0.0002) but not in 2017 (t1 = −0.88, P = 0.3776). In 2016, the arithmetic mean number of black-bellied whistling ducks ducklings exiting boxes in the two basins were 1.2 and 0.8 ducklings, indicating an average of one duckling of this species exited structures. Additionally, an estimated 3,378 wood duck, 531 black-bellied whistling duck, and 19 hooded merganser ducklings exited nest structures in 2016–2017 for an average of six ducklings across species/boxes/years (3,928 ducklings/718 boxes; x̄ = 5.5 ducklings). I also assessed costs of female wood duck recruits from nest boxes, based on contemporary costs to fabricate boxes, their annual maintenance, an assumed longevity of 20 years for an annually maintained bald-cypress (Taxodium distichum) box (total = $142.23/box [U.S.]), reproductive metrics from my study, and a wood duck female recruitment rate of 5.22% (Hepp et al. 1989). Calculated cost per female wood duck …

An Investigation Into The Usability Of An Innovation Management Assessment Tool, Elizabeth Jane Westerlund Gendreau
All Theses
Two tools for assessing external knowledge absorption maturity were developed during Part 1 of this research based upon the work of a previous researcher. The first of these tools assesses the maturity of a single organization, or actor. The second tool assesses the maturity of the collaborative innovation network that actor is a part of. Each tool produces a maturity profile for that actor or network which can then be used to inform innovation strategy decision making. An actor maturity assessment tool had been developed in previous research, however it did not consider how important evaluation criteria were to the …
An Introduction To Homological Algebra And Its Applications, Todd Anthony Morra
An Introduction To Homological Algebra And Its Applications, Todd Anthony Morra
All Theses
Ext modules have a number of applications in homological algebra and commutative abstract algebra as a whole. In this document we prove Ext modules are well-defined and motivate their study by characterizing the depth of a ring in terms of Ext modules as well as by giving an application in combinatorial commutative algebra. In particular, we give a way of constructing Cohen-Macaulay rings from simple graphs and show that when we localize these rings, their type is easily computed by counting the number of maximal cliques in the appropriate simple graph. When R is a noetherian ring and S the …
Vulnerability Of Tri-Colored Bats (Perimyotis Subflavus) To White-Nose Syndrome In The Southeastern United States, Pallavi Sirajuddin
Vulnerability Of Tri-Colored Bats (Perimyotis Subflavus) To White-Nose Syndrome In The Southeastern United States, Pallavi Sirajuddin
All Theses
Tri-colored bats (Perimyotis subflavus) have experienced significant population declines in the southeastern United States due to white-nose syndrome (WNS). The lack of information on the torpor patterns and winter activity in conjunction with the rapid decline from the disease has led to an increased effort in researching the hibernation physiology and wintering activity of P. subflavus and their response to WNS in southern hibernacula. To address this growing concern, we used temperature sensitive radio transmitters to examine torpor patterns in three geographically distinct states and acoustic detectors to monitor bat activity within a WNS-positive hibernaculum. Our specific objectives …
Assessment Of Data Collection Techniques And White-Nose Syndrome Effects On Bat Communities Of South Carolina, Katherine Dennie Teets
Assessment Of Data Collection Techniques And White-Nose Syndrome Effects On Bat Communities Of South Carolina, Katherine Dennie Teets
All Theses
White-nose syndrome (WNS), an infectious disease that has caused massive declines in bat populations since its discovery in 2006, may be indirectly affecting bat community structure. As WNS-susceptible species populations decline, WNS-resistant species may be taking over foraging niches formerly occupied by WNS-susceptible species. We hypothesized that bat communities located in WNS-positive areas in South Carolina have experienced niche partitioning relaxation. First, because some pre-WNS acoustic data were collected using different methods than those primarily used today, we examined if sampling method affected detection probabilities and our interpretation of habitat use of bats. We collected data using passive and active …
Migration Cues And Abundance Estimation Of Imperiled Sturgeon In The Savannah River, Joshua Richard Vine
Migration Cues And Abundance Estimation Of Imperiled Sturgeon In The Savannah River, Joshua Richard Vine
All Theses
Quantitative understanding of reproductive ecology is vital to the conservation and recovery of imperiled fishes. Atlantic Sturgeon (Acipenser oxyrinchus) and Shortnose Sturgeon (Acipenser brevirostrum) are endangered diadromous fish that range across the Atlantic Coast of North America. Historically, populations of both species were exploited for the black caviar trade range-wide. Although moratoria ended commercial harvest, populations are currently threatened by habitat degradation and alteration. This research represents an initiative to increase our understanding of reproductive behavior for both Atlantic and Shortnose Sturgeon by estimating adult population levels as well as the effects of environmental covariates on the initiation of spawning …
Thermal Neutron Characterization And Dose Modeling Of A Plutonium-239/Beryllium Alpha-Neutron Source, Adam Hunter Willey
Thermal Neutron Characterization And Dose Modeling Of A Plutonium-239/Beryllium Alpha-Neutron Source, Adam Hunter Willey
All Theses
Determination of neutron dose can be challenging and requires knowledge of neutron energy and neutron flux. A plutonium-239/beryllium (239PuBe) alpha-neutron source was used to irradiate bacterial samples to create neutron dose response. The goal of this project was to characterize the thermal neutron flux of the 239PuBe alpha-neutron source and model the neutron dose using version MCNPX of the Monte-Carlo N-Particle transport codes. The 37 GBq 239PuBe alpha-neutron source was placed in a neutron “howitzer,” that is, a 2-ft diameter moderating barrel with four radial irradiation ports. Multi-foil activation was used at various distances to determine thermal neutron flux, which …
Developing Optimization System For Improving Highway Network Performance Under Seismic Hazards: A Case Study Of Charleston, Sc, Nixon Wonoto
Developing Optimization System For Improving Highway Network Performance Under Seismic Hazards: A Case Study Of Charleston, Sc, Nixon Wonoto
All Theses
A significant number of bridges in the Central and Southeastern United States (CSUS) are known to have a design that is lacking or no seismic consideration. In an article by Wong et al., Charleston is considered an active seismic zone, and the economic loss from the Charleston region could reach over $14 billion if 1886 Charleston’s earthquake would happen again in the near future. Due to lack of present consideration in seismic design for bridges in CSUS, there has been emerging research that studies retrofit strategies for CSUS region such as in Charleston. However, most of the retrofit program, including …
A Low Cost Mass-Market Deployable Security Approach Against Gps Spoofing Attacks, Muaz Irshad Ahmad
A Low Cost Mass-Market Deployable Security Approach Against Gps Spoofing Attacks, Muaz Irshad Ahmad
All Theses
The Global Positioning System (GPS) is used ubiquitously for navigation and timing synchronization purposes. Many telecommunication, finance and aviation systems rely heavily on GPS information for routine operations. GPS functions by relying on satellites orbiting the earth in very accurately predictable orbits, which are used as references to identify the positions of objects (receivers). Receivers calculate their positions by receiving GPS signals and calculating their relative distances to each of the satellites. With enough relative distances, the receiver can resolve its position using the method known as trilateration [1]. In this thesis, we underline the vulnerability of this orbiting infrastructure …
An Analysis Of Costs And Cost Trends For Southern Forestry Practices, Daniel Callaghan
An Analysis Of Costs And Cost Trends For Southern Forestry Practices, Daniel Callaghan
All Theses
Timber production in the Southern United States has benefited greatly from the use of a range of intensive and sometimes costly silvicultural practices. To aid in the assessment of these costs, costs of forestry practices have been reported periodically for the South for over 60 years; however, few detailed analyses of cost trends have been done. This thesis analyzes changes in silvicultural practices costs in relation to changes in the cost components of these practices as well as larger economic factors and changes in the forest industry. Additionally, discounted cash flow analyses were used to examine possible effects of cost …

Comparing The Therapeutic Efficacy Of Human Amniotic Membrane And Adipose-Derived Mesenchymal Stem Cells In Mitigation Of Osteoarthritis, Mackenzie Catherine Bowman
All Theses
Osteoarthritis (OA) is a leading cause of disability and pain to patients worldwide, and is characterized by abnormal subchondral bone remodeling, such as sclerosis and osteophyte formation, synovial tissue inflammation, and the destruction of articular cartilage, with limited capability for intrinsic repair. Currently, only palliative options are available to help treat the debilitating effects of the disease as there are no therapies authorized to halt or prevent the progression of OA. Due to the destructive nature of OA and a lack of current treatment options, there is an urgent need to develop novel therapies to mitigate the progression of OA. …
Optimization Of Laser Shock Peening Process Using Finite Element Modeling, Sai Hamsini Kosaraju
Optimization Of Laser Shock Peening Process Using Finite Element Modeling, Sai Hamsini Kosaraju
All Theses
Laser shock peening is a cold working process which is used to improve material properties like surface hardness, fatigue life, wear and corrosion resistance, etc. It is widely used to treat turbines, fans, compressor blades, aircraft and automotive parts. When the material is irradiated by high power density laser beams, shock waves are generated, which plastically deforms the material surface and induces high compressive stresses within subsurface area. The amount of residual compressive stress and plastically affected depth depend on laser parameters (laser power density, pulse duration, wavelength, repetition rate, spot size and shape), materials, ambient environment, etc. To improve …

More specifically, it addresses the problem of procedurally generating biologically driven geometry for modeling feathers in computer graphics. As opposed to previously published methods for generated feather geometry, data is derived from a myriad of real-world specimens of feathers and used in creating graphical models of …
An Experimental Study Of Geometric Defects And Their Significance On Material Properties And Behavior, Jody Bernard Bartanus
An Experimental Study Of Geometric Defects And Their Significance On Material Properties And Behavior, Jody Bernard Bartanus
All Theses
Geometric defects play a significant role in affecting both material properties and material behavior. Defects occur in a material due to manufacturing imperfections as well as undesired loading such as incidental impacts. With the popularity of composites and additively manufactured metals in structural applications and component design, the effects of their material-specific defects are important to understand to have confidence in the safety of their intended uses. The use of additive manufacturing (AM) in metals has become a popular choice due to its ability to create geometrically complex parts. In this study, the effect of printed defects and build plate …

Effects Of Performance Pressure On Response Inhibition Performance, Daniel N. Endres
Effects Of Performance Pressure On Response Inhibition Performance, Daniel N. Endres
All Theses
Previous research suggests that psychological pressure tends to exert detrimental effects on action-oriented cognitive tasks. However, the effect of psychological pressure on inhibitory cognitive processes has been relatively overlooked. Consequently, the goal of this study was to examine the effect of psychological pressure on response inhibition performance. Participants (N = 125) were assigned to either a time pressure condition or control condition, and then completed the Stop Signal Task, which tests response inhibition. Outcome variables of interest were stop accuracy, stop signal reaction time, and post error slowing. The results from the study indicated that time pressure significantly impaired stop …
Evaluation Of Soybean Genotypes For Root Morphology, Hardpan Penetrability, Water Use Efficiency, And Yield, Harrison Gregory Fried
Evaluation Of Soybean Genotypes For Root Morphology, Hardpan Penetrability, Water Use Efficiency, And Yield, Harrison Gregory Fried
All Theses
Drought stress has been identified as the major environmental factor limiting soybean (Glycine max L. Merr.) yield in the United States and other parts of the world. Water use efficiency (WUE) that results in greater yield per unit of rainfall is an important parameter in determining crop yields in rain-fed production systems, and is often related with crop drought tolerance. Even though roots are major plant organs that perceive and respond to drought stress, their utility in improving soybean yield and WUE under different environmental and management conditions are largely unclear. The objectives of this research were to evaluate …

Are Values Valuable? Individual Difference Moderators On The Effects Of Economic Stress On Job Satisfaction, Elyssa Johnson
All Theses
Economic stress and financial strain have been shown to have a negative impact on both physical and mental well-being thus making it an important area to continue to perform research on to fully understand how stress impacts individuals (Leana, Mittal & Stiehl, 2012; Sinclair & Cheung, 2016). The proposed study looked to advance research on economic stress by understanding the mediated and moderated mechanisms that impact the relationship between economic stress and job satisfaction. By using a subjective measure of economic stress, perceived income adequacy, as opposed to an objective measure of economic stress such as income, individual differences were …
