City Food: Re-Imagining Urban Food Access Through Holistic, Multilayered Typologies Of Urban Agriculture Systems, Tiffany Managad

All Theses

Urban Agriculture is a growing movement that has resulted in response to the world's increasing urbanization. As global urban populations continue to multiply, the demand to supply healthy and nutritious food to cities has magnified. More than half of the global population now lives in cities and this trend continues to increase exponentially. This phenomena raises the question: How will cities continue to sustain and feed their growing populations now and in the future? Cities are hungry for sustainable ways to grow, access and consume healthier, more delicious food. The current industrialized food system is unsustainable due to escalated dependency …

Enabling Marker-Assisted Breeding (Mab) For Blush In Peach [Prunus Persica (L.) Batsch], Terrence Frett

All Theses

ABSTRACT
Phenotyping is a crucial component for using DNA-based tools in gene discovery and marker development. Phenotypic and genotypic data are essential for linking genetic variation with biological function, thus documenting gene function. However, phenotypic data gathering is not keeping pace with the immensely increasing amount of available genomic information, brought forth by current Next Generation Sequencing technologies. Standardized phenotyping protocols for peach [Prunus persica (L.) Batsch] have been developed for 6 productivity traits (on the tree) and 16 fruit quality traits. Documentation of fruit quality phenotypes has been performed applying developed standardized phenotyping protocol in two seasons, at nine …

The Cinematic Essay: Argumenative Writing And Documentary Film, Zachary Snow

All Theses

The cinematic essay, also known as the essay film, is an extension of the documentary genre which replaces the impossible task of objectivity with a more subjective, argumentative approach. The existence of this form arguably dates back to the birth of the documentary, but certainly encompasses more recent endeavors like Errol Morris' investigative work, the experimental features of Chris Marker, and the political exposes of Michael Moore. Until the recent growth in digital technology, which has decreased the financial burden associated with the cost of film stock and other aspects of production, essayistic cinema was mostly created by professional filmmakers, …

Assessing pitfalls in reproductive efficiency of dairy cattle is often confounded by milk production, animal health, energy balance, and animal management practices, among others. Methods to reduce inefficiencies are classified in the following studies as maternal endocrine management, conceptus recognition, and uterine environment. The goal was to derive some insight into the mechanisms pre and post conception that can alter rates of pregnancy establishment. The initial study ascertained the ability to reduce progesterone (P4) dominance through additional PGF2-alpha (PGF) supplementation on efficiency of timed artificial insemination (TAI) in the Ovsynch® program. The single PGF animals received the standard Ovsynch® protocol …

Assessing Ongoing Sources And Fate Of Dissolved Polychlorinated Biphenyls (Pcbs) In A Stream, Viet Dang

All Dissertations

Polychlorinated biphenyls (pcbs) contamination remains a concern due to their persistence and the risk to human health associated with them. Once released into the environment, these substances are mainly associated with sediment particles and sediment organic carbon matter. They bioaccumulate in organisms via contaminated food and only a small faction is desorbed from sediment into the water column. Given the discontinuity of active discharge, pcbs are currently entering the water via groundwater inputs, soil erosion, and/or ongoing leakage from the point source. It is the dissolved form that 1) can be either absorbed by biofilm attached to stream leaves, which …

Timing Of Exposure To Toxic Tall Fescue: Effects On Beef Cattle Reproduction, Matthew Burns

All Dissertations

Tall fescue [Schedonorus phoenix (Scop.) Holub] is a native grass of Europe and was not widely used in the U.S. until the early to mid 1900's. Toxic tall fescue (E+) is the predominate, cool-season forage used in beef cattle production in the southern U.S., but grazing this forage is known to negatively impact growth and may impair reproductive performance. Two- and 3-yr old (young) beef cattle respond differently to synchronization protocols and have higher energy requirements compared with mature cows under normal management conditions. Interestingly, limited data indicate that young cattle reproductive performance is negatively impacted to a greater extent …

Bioengineering Approach To Understanding Tmj Pathobiology, Jonathan Kuo

Choline Supplementation And Dna Methylation In The Hippocampus And Prefrontal Cortex Of Rats Exposed To Alcohol During Development, Nicha K H Otero, Jennifer D. Thomas, Christopher Saski, Xiaoxia Xia, Sandra Kelly

Publications

BACKGROUND:

Some of the most frequent deficits seen in children with fetal alcohol spectrum disorders (FASD) and in animal models of FASD are spatial memory impairments and impaired executive functioning, which are likely related to alcohol-induced alterations of the hippocampus and prefrontal cortex (PFC), respectively. Choline, a nutrient supplement, has been shown in a rat model to ameliorate some of alcohol's teratogenic effects, and this effect may be mediated through choline's effects on DNA methylation.

METHODS:

Alcohol was given by intragastric intubation to rat pups during the neonatal period (postnatal days 2 to 10) (ET group), which is equivalent to …

A Goal Setting Intervention Positively Impacts Adolescents’ Dietary Behaviors And Physical Activity Self-Efficacy, Mical Kay Shilts, Marilyn S. Townsend

Journal of Youth Development

The efficacy of a youth development intervention on improving eating and physical activity(PA) self-efficacy, goal attainment scaling, goal effort, and behaviors was examined in a repeated measures, quasi-experimental field trial. Ethnically diverse students (n=64) from a low-income middle school participated in the 10-session intervention driven by the Social Cognitive Theory with a Goal Setting Theory emphasis. Participants, 13-14 years old, made significant changes in dietary behaviors ( P=0.03) and PA self-efficacy (P=0.02) after receiving the intervention. Self-efficacy did not mediate dietary behavior change but did mediate the small changes made in PA. Goal effort was not a mediator of behavior …

A Measure Of Self-Efficacy Among Agency Directors To Offer Nutrition Education To Lowcountry Food Bank Clients, Lucie Maguire

All Theses

In 2005, the Lowcountry Food Bank (LCFB) in Charleston, SC, launched an initiative to provide nutrition education to clients that seek food assistance. The agency directors of the 332 member agencies of the LCFB are in direct contact with clients, therefore they could provide nutrition education rather than the LCFB staff alone. As such, the self-efficacy of agency directors to deliver nutrition education must be measured. The objective of this project was to measure the self-efficacy of agency directors of the LCFB. A 17-item instrument measuring self-efficacy was developed, including ten validated items from the General Self-Efficacy Scale and an …
