Results indicated that the inclusion of practice activities in mobile instruction has a positive effect on student performance. Study participants …

Science Fictional Transcendentalism In The Work Of Robert Smithson, Eric Saxon

School of Art, Art History, and Design: Theses and Student Creative Work

In studies of American artist Robert Smithson (1938-1973), scholars often set the artist’s early abstract expressionist and Christian iconographical paintings apart from the rest of his body of work, characterizing this early phase as a youthful encounter with the enduring legacy of abstract expressionism in the late 1950s to early 1960s as well as a temporary preoccupation with ritualized Catholic imagery. This thesis argues for the inclusion of this early phase into Smithson’s career as a foundational period in which he established the set of problems that artistically engaged him throughout his life: issues of temporality, materiality, and universal entropy. …

Decentralized Collision Avoidance, Jayasri K. Janardanan

School of Computing: Dissertations, Theses, and Student Research

Autonomous Robots must carry out their tasks as independently as possible and each robot may be assigned different tasks at different locations. As these tasks are being performed, the robots have to navigate correctly such that the assigned tasks are completed efficiently, while also avoiding each other and other obstacles. To accomplish effective navigation, we must ensure that the robots are calibrated to avoid colliding with any kind of object on its path. Each robot has to sense the obstacles on its path and take necessary corrective measure to avoid those obstacles. In a situation with multiple robots, robots may …

Evaluation Of Collection Method And Diet Effects On Apparent Digestibility And Energy Values Of Swine Diets, Yanshuo Li

Department of Animal Science: Dissertations, Theses, and Student Research

Two experiments were conducted to investigate the effects of collection method and diet on estimating digestibility values. In Exp. 1, 24 barrows were fed either a corn-soybean meal diet (CSBM) or CSBM with 20% dried distillers grains with solubles (DDGS). Fecal collections were based on exact timing (Day collection) or marker-to-marker collection (MM) methods during a 4-d period. Diets contained 0.5% of titanium dioxide (TiO₂) for estimating digestibility using the index method. In Exp. 2, the effects of collection method and basal diet on determination of DDGS digestibility were studied using 24 barrows. Diets were CSBM (basal 1), …

Use Of Alkaline Treated Crop Residues As Partial Grain Replacements For Finishing Cattle, Adam L. Shreck

Department of Animal Science: Dissertations, Theses, and Student Research

Recently, corn has become expensive and this has led to high feed costs and decreased profitability. High priced corn has allowed for the consideration of other ingredients as replacements to reduce diet cost. In much of the Corn Belt, supplies of wet or modified distillers grains and crop residues are abundant. These ingredients were investigated as corn replacements. Studies were conducted to identify methods for treating crop residues to improve digestibility and value in finishing diets based on corn grain and corn wet distillers grain with solubles (WDGS). Digestibility and value of crop residues were improved by mild chemical treatment. …

Local Adaptation To Climate Change In A Calcareous Grassland System, Catherine Ravenscroft

Biology - Dissertations

Annual manipulations of temperature and rainfall have been maintained in intact calcareous grassland since 1993 at the Buxton Climate Change Impacts Laboratory (BCCIL) in northern England (UK). Here I investigated the role of local adaptation as mechanism of the apparent resistance of species' to long-term climate manipulations at BCCIL using a common forb, Plantago lanceolata. Plantago lanceolata is a rosette-forming, perennial herb of wide-ranging distribution, and one of the more common forbs in calcareous grasslands, including BCCIL. In the first study I used a common garden approach to test for evidence of selection for different suites of functional traits in …

Supportive Alignments & Teams In Group Supervision For School Counselors-In-Training, Christopher Sean Perrello

Communication and Rhetorical Studies - Theses

This thesis focuses on the formation of supportive alignments and interactional teams through particular linguistic strategies within the group supervision classroom, especially as participants provide one another with feedback on their professional behaviors. Through discourse analysis of transcripts of a video-recorded group supervision meeting, I illustrate how graduate level school counselors-in-training use language to construct alignments and teams. Discursive features that are identified and explicated include positive assessments of others, repetition, co-narration, constructed dialogue, and matching. In investigating these particular linguistic strategies, I emphasize how some of the major goals of group supervision (including feedback and reflection) are discursively expressed …

Nowadays, more and more people are having pets as members of their family. To the year of 2012, there are 78.2 million dogs and 86.4 million cats owned in the U.S according to the report of the Humane Society of the U.S. The pet food industry as a result has been prosperous, with an estimated market size of $21 billion in the year of 2013. However, there is a common problem for the industry - fat rancidification. Pet foods usually contain relatively high levels of fat, which, if not well protected, are prone to oxidation and generate unfavorable products including …

Recreating And Simulating Digital Costumes From A Stage Production Of Medea, Anuradha Pinisetty

All Theses

This thesis investigates a technique to effectively construct and simulate costumes from a stage production Medea, in a dynamic cloth simulation application like Maya's nDynamics. This was done by using data collected from real-world fabric tests and costume construction in the theatre's costume studio. Fabric tests were conducted and recorded, by testing costume fabrics for drape and behavior with two collision objects. These tests were recreated digitally in Maya to derive appropriate parameters for the digital fabric, by comparing with the original reference. Basic mannequin models were created using the actors' measurements and skeleton-rigged to enable animation. The costumes were …

All Theses

This thesis presents a method for integrating two algorithms, fractal flames and wisps, to create visually rich and interesting patterns with 3D volumetric structure. Twenty-one single 3D flame variations are described and specified. These patterns were used to produce an aesthetically designed animation, inspired by both Hubble Telescope photographs and data from a simulation of a predicted collision between the Milky Way and Sagittarius galaxies. The thesis also describes Python tools and a Houdini pre-visualization pipeline that were developed to facilitate the animation design and production.

Genetic And Environmental Determinants In The Evolution Of Alternative Mating Strategies In The Sailfin Molly, Poecilia Latipinna (Poeciliidae: Poecilia: Mollienesia), Elizabeth Lange

All Theses

Understanding the genetic and environmental factors responsible for differences in size, morphology and behavior can aid in determining how alternative male mating strategies evolve in natural populations. One important environmental factor is nutrition, as it underlies growth of both body size and morphological traits that are linked to alternative mating strategies in many animals. In sailfin mollies, Poecilia latipinna , male size is fixed at maturity, highly variable within populations and correlated with dorsal fin morphology and expression of alternative male mating behaviors. Large males with exaggerated dorsal fins use courtship behavior while small males with reduced dorsal fins use …

Comparison Of Methods To Evaluate Chitosan As An Antimicrobial Against Listeria Spp. Cultures, Scott Hartley

All Theses

The antimicrobial properties of a chitosan-coated vacuum-packaged pouch were tested against Listeria monocytogenes (LM) inoculated on frankfurters. A 1.5% chitosan solution was successfully coated onto a corona-treated poly/nylon based film and then heat-sealed to form a pouch. An initial 5 log CFU/mL population of LM was used to inoculate a frankfurter in the pouch, which was then vacuum-sealed and stored at 4¡ and 13¡ C for a period of 8 weeks, with bacteria enumeration performed on weekly intervals. An uncoated pouch was tested as a control. It was found that the chitosan-coated pouches did not exhibit any antimicrobial properties against …

Black Bear Encounters In The Wildland-Urban Interface Of Upstate South Carolina, Victoria Luke

All Theses

As humans move into more remote areas wildlife are displaced and there are an increasing number of human-wildlife interactions. Human dimensions research is important in order to understand social components necessary to maintain healthy wildlife populations while also maintaining healthy relationships between wildlife and the local community. In upstate South Carolina, the number of wildlife nuisance calls received by the Department of Natural Resources has increased. More importantly, wildlife populations, particularly the American black bear (Ursus americanus), continue to move into urban areas. The following study explores black bear encounter report calls coming into the SC Department of Natural Resources …

The Development Of A Rapid Fiber-Based Immunoassay As A Point-Of-Care Or In-Home Diagnostic Test, Christopher Waddell

All Theses

Early diagnosis of conditions allows for physicians to treat patients earlier, and ultimately improve patient outcomes. Two conditions of particular interest for earlier and cheaper diagnosis are the influenza virus and human immunodeficiency virus (HIV). Antiviral treatment administered within the first 48 hours of influenza infection decreases symptom severity, risk of complications, and reduced healthcare costs. Early diagnosis of HIV can decrease the risk of transmission of the virus to HIV negative individuals and allow for earlier administration of highly active antiretroviral treatment (HAART), improving patient quality of life and patient outcomes.
Currently, the 'gold standard' for detection of both …

Individual Behavioral Variation Of Juvenile Spiny Lobster (Panulirus Argus) Denning Behaviors And The Role It Plays In Shelter Competition During Habitat Loss, Katherine Heldt

All Theses

Variation in juvenile spiny lobster (Panulirus argus) aggressive and gregarious behaviors may play an important role in structuring population level interactions. Since aggressive and gregarious behaviors were not repeatable and were found to be highly correlated with size, these behaviors were found to be largely driven by a combination of behavioral plasticity and ontogeny. Although larger individuals were found to be the most aggressive and least gregarious individuals, often occupying crevice shelters by themselves, they did not exclude smaller, less aggressive lobsters from crevice shelters. Surprisingly, in shelter limited situations, small, less aggressive individuals were more likely to use dens …

Continuum Robotic Surface: Forward Kinematic Analysis And Implementation, Jessica Merino

All Theses

This thesis presents a new class of biologically inspired robots: continuum robotic surfaces. This work is fueled by the question: can the interaction between robot and environment be advanced with “programmable surfaces in space?” The novelty of continuum robotic surfaces lies in their ability to be actively controlled and reconfigured in what we believe is the current “missing dimension” in robot movements — two–dimensional space. We believe that such surfaces will lend themselves to more complex applications. However, to effectively deploy such surfaces for these complex applications, kinematic models will be necessary to plan and control desired configurations. The forward …

Functional Analysis Of A Glutathione S-Transferase Gene From Reniform Nematode On Soybean, Jing Hou

All Theses

Nematode glutathione S-transferases (GSTs) have been implicated in plant-nematode interactions as effector proteins with an important role in the establishment of feeding sites. Studies with root-knot nematode in Arabidopsis thaliana suggest that GSTs may protect the nematode against oxidative plant defenses and modulate plant responses to parasitism. Our objective was to study the function of a GST from reniform nematode (Rotylenchulus reniformis) in soybean. We used a virus-induced gene silencing (VIGS) system, utilizing a Bean pod mottle virus (BPMV)-based vector and a partial sequence of gsts-1 from Meloidogyne incognita to silence the putative reniform nematode homolog. The effect of silencing …

Biological Production Of Succinic Acid Using A Cull Peach Medium, Janani Krishnakumar

All Theses

Biological production of succinic acid from a cull peach based medium was studied using Escherichia coli AFP 184 in a dual-phase batch process including an aerobic growth phase and an anaerobic production phase. Experiments were performed to study the effects of corn steep liquor supplement and exogenous hydrogen supply. About one half of the sucrose in the medium was converted to fermentable sugars glucose and fructose during sterilization. The remaining sucrose was hydrolyzed with invertase. The viscosity of the medium was reduced from 350 cP to 50 cP to allow efficient oxygen transfer by a commercial enzyme product. In the …

Analyses Of Multivitamins In Nutraceuticals By Reverse Phase Hplc With Dad, Elsd And Ms, Hsiang-Chi Huang

All Theses

ABSTRACT
Vitamins are essential to human beings and support long-term healthy lifestyle. They exist widely in food, but in small amount. Hence, dietary supplements and fortified food products are more and more popular in the nutritional markets. According to the Infant Formula Act of 1980, the range of each of the nutrients should fall within a specific range or above the required minimum, so there is an increasing interest of accurate measurement of vitamins, particularly the B-group vitamins. However, traditional methods for vitamin B analyses are time-consuming and often in poor accuracy. As a result, rapid and reliable analytical methods …

Imagining A Common Ground: Place, Community, And The Possibility For Place-Based Education Through Flannery O'Connor's 'Greenleaf', Christine Mahoney

All Theses

Through literature, news outlets, media, parents, teachers, and peers, youth are currently being made aware that there are severe problems in the environmental and social realms. However, the imagined but representative stories found in literature also offer opportunities for students to learn how to combat these crises, and instilling the value of place in students through pedagogy will help them become proactive adults. The particular dynamic between community and place is one we see at work in “Greenleaf” by Flannery O'Connor, an author who has been left out of ecopedagogical conversations but can be useful in finding imaginative connections between …

Development Of Hplc Methods For The Determination Of Water-Soluble Vitamins In Pharmaceuticals And Fortified Food Products, Hung Khiem Trang

All Theses

Though many HPLC methods have been developed and reported in literature for vitamin analysis for the past two decades, applying certain methods directly from literature more than often fails to reproduce the results reported due to many variables of liquid chromatography. This issue was targeted in this project through the examination of chromatographic behaviors of water-soluble vitamins in order to help the analysts better modify methods from literature or even develop new methods from scratch to fit their analytical need with the resources available (e.g., columns, detectors, etc.) in their lab.
The first part of the project investigated the chromatographic …

Avian Community Response To Fire-Mediated Regeneration Of Native Pine Stands In The Mountains Of South Carolina, Curtis Walker

Route Segment Level Analysis Of Bus Safety Incidents, James G. Strathman, Sung Moon Kwon

Urban Studies and Planning Faculty Publications and Presentations

This paper analyzes collision and non-collision incidents that occurred on TriMet’s bus system over a near two-year period. The bus route network was decomposed into stop and line haul segments, and a typology of models was estimated from segment level incident, risk exposure, and roadway feature data. The frequency of non-collision incidents – mainly slips, trips and falls – was estimated to be primarily related to associated risk exposure variables. The frequency of collision incidents was also estimated to be related to risk exposure variables, as well as a number of roadway design variables. The findings serve as an initial …

Neiman Marcus Chicken Coops: Exploring Class And Identity Through Backyard Chicken Keeping And The Contemporary Food Movement, Traci D. Joseph

Masters Theses

This paper is a case study of a proposed backyard chicken ordinance for Grand Rapids, Michigan. The study is viewed in light of social movement theory, specifically new social movement theory, to determine if events surrounding and leading up to the debate can be labeled as a social movement. A key finding is a culture of consumption as a common thread throughout the debate. The poultry industry pushed for continued consumption of its products with an agenda of fear regarding disease and improper handling. Proponents countered with a discussion on an ethic of care for the birds. Ultimately, this rejection …
