Enhancing Native Pollinators Of Watermelon Agroecosystems In South Carolina, Miriam Meryl Jenkins

All Dissertations

Widespread declines in both managed and wild pollinators worldwide has led to increasing concern for the valuable ecosystem services they provide for natural systems and agriculture. This study examined the potential benefits of diversifying agricultural landscapes by increasing floral diversity on farms on insect biodiversity and crop pollination services. My focal species, watermelon Citrullus lanatus, is an ideal species for pollination studies because it is entirely dependent on insect pollinators to set fruit. Chapter 1 investigates the effect that wildflower strips on watermelon farms has on the delivery of pollination services to watermelon by the pollinator community. Chapter 2 presents …

Integrating Self: A Story About A Tomato, Thomas Scott Rapp

All Theses

Tomato is a two-dimensional, animated, short film about the interaction between a farmer and a tomato plant. Through conceptually-driven technique, the film intends to relate the emphasis of tactility and self-reflection in animation to the care of a plant that could provide a valuable fruit. Using digital tools, like Adobe Animate, Photoshop, After Effects, and Premiere, as well as material identification techniques, I created the film as an exhibition of a method designed to integrate hand-crafted elements into digital workflow.

Goosegrass Biology, Genetic Diversity And Innovative Control Measures, Robert Kerr

All Dissertations

Goosegrass (Eleusine indica (L.) Gaertn.), a C4 grass found in most areas of the world, is one of the most troublesome weeds in tropical and temperate environments. Turfgrass systems are intensely managed and frequently used for a number of different sporting pursuits. Due to high traffic, these areas become compacted and maintaining a healthy sward of dense turfgrass can be challenging, as a result these areas can become infested with weeds such as goosegrass. Understanding a weeds life cycle and biology is fundamental in developing control strategies. Three main areas of interest in regards to goosegrass biology and control …

Community Bike Shops As Youth Development Programs: Influences On Mobility & Accessibility Of Youth Participants, Adrienne Warren

All Theses

Lack of mobility in low-moderate income neighborhoods can lead to mobility-based social exclusion and can contribute to a path of generational poverty, diminished quality of life, among other health and socio-economic disadvantages for residents. Community bike shops provide opportunities for youth residents in low-moderate income neighborhoods to learn new mechanical and riding skills through earn-a-bike programs in addition to providing access to a bicycle and facilitate group riding experiences. These new experiences can improve student’s mobility and accessibility and thus help alleviate mobility-based exclusion. A mixed methods case study of two community bike shops, Village Wrench in Greenville, South Carolina …

Quantitative Approaches To Upland Game Bird Conservation In Kansas, Alexander Schindler

All Theses

The Great Plains region of North America is an important ecosystem supporting many plant and animal species, but one of the most endangered ecosystems in the world. Loss and degradation of grasslands in the Great Plains region has resulted in major declines in abundance of grassland bird species. To ensure future viability of grassland bird populations, it is crucial to evaluate specific effects of environmental factors across species to determine drivers of population decline and develop effective conservation strategies. In this study, I took a multi-species approach to understanding effects of environmental factors on four species of upland game birds …

The Impact Of Color On Visual Retention And Preference In Logo Design, Aaron Taylor Alexander

All Theses

Color is often the first thing a person will be drawn to in an object. It fills the world and activates people’s imagination. The purpose of this research is to analyze the impact that color has on a person’s ability to recall visual information. Company logos are used as a focus for this due to the importance a logo has in the way companies market themselves. Therefore, a logo should be memorable at a second’s glance.

This thesis attempts to solve the problem of understanding what makes a logo more memorable to a customer in order to assure maximum visual …

Culinary Medicine: An Evaluation To Assess The Knowledge, Attitudes, Behaviors And Confidence Of 1st Year Medical Students In A Culinary Medicine Teaching Kitchen, Lauren Elizabeth Vanderpool

All Theses

The World Health Organization predicts that two-thirds of all disease around the globe will be the result of lifestyle choices by the year 2020. Increasing obesity rates contribute to these climbing numbers. The direct relation between obesity and comorbidities such as cardiovascular disease (CVD), Type II Diabetes, and hypertension cannot be denied. Obesity is directly associated with higher risks of developing CVD, Type II Diabetes, hypertension, and many other health conditions. All of the aforementioned health conditions are associated with physical activity, nutrition and other lifestyle behaviors. In order to combat these extremely prevalent health conditions, it is ideal to …

Development Of Tissue Engineered Vascular Grafts Resistant To Diabetes Mellitus, Jhilmil Dhulekar

All Dissertations

Diabetes Mellitus, characterized by high levels of blood sugar, is a significant risk factor for cardiovascular disease. Almost 25 million Americans are currently diagnosed with diabetes, with numbers rising rapidly. Hyperglycemia and dyslipidemia coexist in diabetes and result in inflammation, stiffening and degeneration in blood vessels which contributes to the development of atherosclerosis and arterial diseases such as coronary and peripheral artery disease. The diseased arteries can be replaced with synthetic materials, but the small-diameter arterial replacements (< 6 mm diameter) fail after 5-10 years because they are not resistant to the damage associated with diabetes. Tissue engineering offers a promising approach to develop decellularized extracellular matrix-based vascular scaffolds, repopulated with the patients’ own stem cells, to provide a non-immunogenic, patient-tailored vascular graft with improved remodeling and integration with native tissue. However, the presence of diabetes will structurally modify the implanted tissue engineered grafts. Therefore, it is necessary to develop tissue engineered vascular constructs capable of resisting diabetes-related alterations. The primary focus of this research was threefold: 1) Develop decellularized vascular scaffolds derived from porcine renal arteries with matrix integrity and mechanical properties similar to native blood vessels, 2) test the resistance of scaffolds treated with penta-galloyl glucose (PGG) to diabetes in functional small animal model, and 3) determine the immunomodulatory effect of adipose derived stem cell differentiation and seeding on scaffold remodeling in a diabetic environment.

First, a complete decellularization procedure of porcine renal arteries was established and optimized to remove all cellular and nuclear material from the …

Fat-Soluble Vitamins In Dietary Supplements: Optimization Of Extraction, Simultaneous Determination By Hplc And Stability Studies, Yaqi Wang

All Dissertations

In recent decades, consumption of multivitamin/mineral (MVM) dietary supplements has significantly increased, reflecting a huge demand from the commercial market. Meanwhile, there is a big concern of the stability and shelf-life of vitamins, including fat-soluble vitamins (FSVs), in the dietary supplements. Therefore, it is necessary to conduct precise analysis and stability evaluation of the FSVs in the commercial products so as to scrutinize their content levels.

An optimized method to extract the encapsulated FSVs (i.e., vitamin A acetate, vitamin A palmitate, vitamin D3 and vitamin E succinate) from MVM supplements was developed in light of four critical factors, including the …

The Role Of Tbx5 In Sinoatrial Node Differentiation In Mouse Embryonic Stem Cell Derived Cardiomyocytes, Yunkai Dai

All Dissertations

The sinoatrial node of the mouse embryo arises from the wall of the right atrium near the border of the sinus venosus. Early in development this region expresses the transcription factor Tbx5. Because of this, Tbx5 is thought to sit at the apex of a transcriptional cascade leading to sinoatrial node (SAN) differentiation. To test this we produced a mouse embryonic stem cell line B1 (pTripZ-mTbx5; αMHC::GFP) that conditionally overexpresses Tbx5, to determine if this would lead to enhanced SAN differentiation. We found that ES cells overexpressing Tbx5 showed enhanced overall cardiac differentiation and that cardiac cells showed increased beat …

Metabolic Adaptation During Infection In The Intestinal Parasite Entamoeba Histolytica: Roles Of Pfk Enzymes, Irem Bastuzel, Cheryl Ingram-Smith

Graduate Research and Discovery Symposium (GRADS)

Entamoeba histolytica is a water- and food-borne intestinal parasite that causes diarrheal disease in an estimated 90 million people each year worldwide. This pathogen encounters many different environments during infection and must adjust its metabolic activities specifically to that environment. Entamoeba lacks many common metabolic pathways and must ingest other cells to obtain many of the cellular building blocks such as amino acids that it cannot synthesize itself. E. histolytica relies on breakdown of the sugar glucose as the main means for obtaining energy. This is done through glycolysis, a metabolic pathway that is present in essentially all organisms. A …

Screening Unsaturated Fat Sources Included To Low And High Forage Diets With Different Fat Dietary Concentration Using An In Vitro Gas Production System, Saad M. Hussein, M. X. Toledo, S. Twyman, O. Thomas, J. Echesabal, Gustavo J. Lascano

Graduate Research and Discovery Symposium (GRADS)

Fat inclusion can increase energy density of diets fed to ruminants, but detrimental effects to nutrient digestion have been reported. There is evidence that not all fat sources have this negative response and this effect can vary depending on the forage concentration in the diet. The objective of this experiment was to determine the effects of including different types of unsaturated fats to high and low forage diets in vitro digestibility and fermentation. An experiment was conducted using an in vitro gas production (GP) system. Treatments included either low forage (LF; 35%) or high forage (HF; 70%) with 2 dietary …

Evaluation Of Soybean [Glycine Max (L.) Merr.] Genotypes For Yield, Water Use Efficiency, And Root Traits, Harrison Gregory Fried, Sruthi Narayanan, Benjamin Fallen

Publications

Drought stress has been identified as the major environmental factor limiting soybean [Glycine max (L.) Merr.] yield worldwide. Current breeding efforts in soybean largely focus on identifying genotypes with high seed yield and drought tolerance. Water use efficiency (WUE) that results in greater yield per unit rainfall is an important parameter in determining crop yields in many 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 …

Use Of Physical Activity Monitoring Devices By Families In Rural Communities: Qualitative Approach, Iryna Sharaievska, Rebecca A. Battista, Jennifer Zwetsloot

Publications

Background: Several studies support the impact of information communication technology–based interventions to promote physical activity among youth. However, little is known on how technology can be used by the entire family to encourage healthy behavior. Previous studies showed that children and youth rely and are dependent upon the decisions and values of their caregivers when it comes to having a healthy lifestyle. Thus, the exploration of behavior and attitudes of the entire family is needed.

Objective: The study aimed to explore (1) perceptions of how the use of physical activity tracking devices (Fitbit Zip) by families in rural communities influence …

Realmente Tenemos La Capacidad: Engaging Youth To Explore Health In The Dominican Republic Through Photovoice, Catalina Tang Yan, Arelis Moore De Peralta, Edmond P. Bowers, Linda Sprague Martinez

Publications

Youth are often at risk for physical and psychosocial illnesses, and yet their input is rarely included in health assessments and interventions. Two U.S.-based universities partnered with community stakeholders and youth in Las Malvinas II, Dominican Republic to explore factors that promote and/or hinder the health of youth in Las Malvinas II. Youth (n=8) conducted a photovoice, and identified six key health priorities: (1) good nutrition, (2) depression and poverty, (3) violence, (4) sports and neighborhood association, (5) education, and (6) sanitation and community infrastructure. Findings revealed youth’s exploration of complex multi-level determinants of health. This study suggests youth have …

The Role Of Social Media In Enhancing Risk Communication And Promoting Community Resilience In The Midst Of A Disaster, Kathryn E. Anthony, Steven J. Venette, Andrew S. Pyle, Brandon C. Boatwright, Carrie E. Reif-Stice

Publications

The importance of engendering community resilience after a disaster event cannot be overstated. In this chapter, we argue that the strategic design of risk communication messages is critical for communities affected by crises. In the past, many communication practitioners employed the single shot, top-down approach for constructing messages, especially during crises. Given growing recognition of the ineffectiveness of this model, scholars have become more attentive to the role of message design in conveying risk to stakeholders. Specifically, through the lens of the message convergence framework, we argue the need for a multiple messages approach that targets diverse groups of people …

Sibling Sex, But Not Androgens, Shapes Phenotypes In Perinatal Common Marmosets (Callithrix Jacchus), Brett M. Frye, Lisa G. Rapaport, Michael W. Sears, Talia Melber, Suzette D. Tardif

Publications

When offspring share a womb, interactions among fetuses can impart lasting impressions on phenotypic outcomes. Such intrauterine interactions often are mediated by sex steroids (estrogens and androgens) produced by the developing fetuses. In many mammals, intrauterine interactions between brothers and sisters lead to masculinization of females, which can induce fitness consequences. Many litter-bearing primates, though, seem to escape androgen-mediated litter effects, begging why? Here, we investigated how the sex composition (i.e., same- or mixed-sex) of litters influences perinatal outcomes in the common marmoset monkey (Callithrix jacchus), using a combination of physiological, morphological, and behavioural assays. We hypothesized that …

The Effects Of Planting Date And Varietal Susceptibility Of Gossypium Hirstutum L. On Thrips, Cody D. Kerns

All Theses

Thysanoptera (Haliday), or thrips, are minute, polyphagous insects known globally for their role as crop pests. One species important economically to South Carolina and the southeastern United States is the tobacco thrips, Frankliniella fusca (Hinds). This species is the most predictable pest of upland cotton, Gossypium hirstutum (L.). Thrips are particularly damaging to cotton when they infest seedling cotton. In some years, tobacco thrips are recorded as the most detrimental pest of cotton in terms yield loss. Yield loss from tobacco thrips infestations varies widely between years and even within the same year. By analyzing agricultural control practices, an accurate …

Online Child’S Health Assessment Tool For Obesity Prevention Programming, Laura Palmer, Kimberly Mccarthy, Daniel Perkins, Lynne Borden

Journal of Youth Development

To optimize public health in the next decade, prevention of childhood obesity will remain a central focus. To impact behavioral change, data must be linked to continuous quality improvements within existing nutrition and physical activity programming. The Children, Youth, and Families At-Risk Professional Development and Technical Assistance Center has developed a picture-based, online survey tool, the CYFAR Health Assessment Tool (CHAT), to assess health behaviors in youth ages 6 to18 years of age. Used for continuous program improvement, aggregate data results are coupled with tailored health recommendations in 4 domains (behavior and environmental modifications, education, and direct strategies) and evidence-informed …

Teens As Teachers In The Garden: Cultivating A Sustainable Model For Teaching Healthy Living, Virginia Bolshakova, John Gieng, Sheena Sidhu, Mary Vollinger

Journal of Youth Development

School gardens are an ideal space to deliver a healthy living curriculum, such as nutrition and physical activity education, to elementary school youth. However, public schools often lack the resources and support to establish sustainable garden-based programming. We created the Healthy Living Ambassador program, a collaborative after-school garden program in low-income communities that brought together resources from schools, community programs, and University of California Cooperative Extension. This school garden program featured culturally competent teens as teachers to serve as near-peer educators and mentors to elementary school youth. The program development model incorporated lessons from sustainable community-based health program interventions and …
