Comprehensive Benefits Of Green Roofs, Madison R. Gibler

Masters Theses

"Green infrastructure uses vegetation, soils, and natural processes to manage water and create healthier urban environments, providing traditional roof services and alternative stormwater management technologies. Other benefits and impacts are not yet fully understood or valued. Research conducted assesses specific stormwater benefits of green roofs, providing information on nutrient leaching from media; and analyzes potential energy benefits through side-by-side comparisons of full-scale white, traditional black rubber, and green roofs in the mid-continent Missouri climate. Roofing media selection impacted leaching of nutrients, suspended solids, and organic carbon from the tested green roof media. Thermal properties were investigated at the building level, …

Large-Scale Spatiotemporal Spike Patterning Consistent With Wave Propagation In Motor Cortex, Kazutaka Takahashi, Sanggyun Kim, Todd P. Coleman, Kevin A. Brown, Aaron J. Suminski, Matthew D. Best, Nicholas G. Hatsopoulos

Biomedical Engineering Faculty Research and Publications

Aggregate signals in cortex are known to be spatiotemporally organized as propagating waves across the cortical surface, but it remains unclear whether the same is true for spiking activity in individual neurons. Furthermore, the functional interactions between cortical neurons are well documented but their spatial arrangement on the cortical surface has been largely ignored. Here we use a functional network analysis to demonstrate that a subset of motor cortical neurons in non-human primates spatially coordinate their spiking activity in a manner that closely matches wave propagation measured in the beta oscillatory band of the local field potential. We also demonstrate …

The Influence Of Self-Reported Degree Of Masculinity/Femininity On Condom Use Among Black Men Who Have Sex With Men In The Deep South, Elizabeth D. Peeler

Theses and Dissertations

In the United States, 50,000 Americans are diagnosed with HIV each year (CDCa, 2014). The HIV/AIDS epidemic has had a particularly devastating impact on the southern U.S., especially the Deep South – Alabama, Georgia, Louisiana, Mississippi, North Carolina, and South Carolina (Reif, Whetten, Wilson, McAllaster, Pence, Legrand, & Gong, 2014). The Deep South, while only composing of 36% of the national population, accounts for 50% of all people living with HIV/AIDS in the nation (Human Rights Watch, 2010). No other population has been hit harder than men who have sex with men (MSM; Prejean, Tang, & hall, 2013). Black MSM …

Revival Of The Fittest: A Return To Writer Subjectivity In Composition, Ashley Mcclary

Theses and Dissertations

Writing can be unpleasant. And most examples of good writing start from early attempts to identify a partial understanding of complex, complicated concepts that emanated from a willingness to be honest and open and smart about the surrounding world. The inception of a good text—especially when paired with the strength to fulfill an incessant, ridiculous desire to tell a truth—can produce an affected writing sample, one of purpose and presence. In the field of Composition, when instructors ask students to write and suggest they do it well, it is easy to overlook the demand that students take new risks in …

On Testing Common Indices For Several Multi-Index Models: A Link-Free Approach, Xuejing Liu

Doctoral Dissertations

"To avoid the curse of dimensionality, and to help us better understand the structure of the high dimensional data, methods for dimension reduction are clearly called for. The common linear dimension reduction techniques for single population include principal component analysis (PCA) which is unsupervised in regression and supervised Partial Least Squares (PLS). Modern sufficient dimension reduction techniques, like the ones we consider, constitute a form of supervised linear dimension reduction which outperform PCA and PLS without the underlying model assumptions.

In practice, we often deal with situations where the same variables are being measured on objects from different groups, and …

Occurrence, Monitoring And Removal Of Drinking Water Contaminants By Advanced Technologies, Danielle Marie West

Doctoral Dissertations

"In order to maintain drinking water primary standards compliance under the USEPA Stage 2 Disinfectant Disinfection Byproducts Rule, drinking water treatment plants (DWTPs) are switching from free chlorine (FC) to chloramines (MCA). Concerns are raised as MCA disinfection has been linked N-nitrosamine formation. N-nitrosamines are a group of nitrogenous DBPs (N-DBPs) which are highly carcinogenic in comparison to regulated DBPs (THMs and HAAs, generated by FC disinfection). Also in the forefront of drinking water concerns are other emerging drinking water contaminants such as perchlorate. Perchlorate is a contaminant which can enter drinking water from natural deposits or through introduction by …

Detection And Removal Of Emerging Environmental Contaminants, Ruipu Mu

Doctoral Dissertations

"Water is a very crucial natural resource for human. The increasing number of contaminants detected in water bodies has drawn considerable increasing attention over the last decade. There are numerous emerging environmental contaminants which may cause serious health issues. The recent occurrence studies of these contaminants show both industrial and household activity introduction of chemicals into water resources. These various sources result in a large variety of chemicals such as explosives, pharmaceutical and personal care products (PPCPs) and disinfection byproducts detected in water worldwide. Due to the relatively low contaminant concentrations, development of new and improved detection methods along with …

Tree-Sway Frequency And The Turbulent Co-Spectral Gap In A Dense Canopy Environment, Katherine L. Ertell

Theses and Dissertations

Today, knowledge of canopy turbulence comes solely from field observations. However, measurements or field observations that are taken at a specific location within the canopy cannot accurately capture the interaction of the wind and the canopy it crosses. Without this complete picture of the atmosphere, the temporal fluctuations that exist in turbulent flows cannot be understood. From an atmospheric perspective, the complex structure of forests significantly influences turbulence in the atmospheric boundary layers (ABL) by consistently imposing both mechanical and thermal forces. This study explores the temporal and spatial characteristics of tree-sway motions and their aerodynamic interactions with coherent turbulence …

Buder Center for American Indian Studies Research

American Indian and Alaska Natives youth and adults experience higher rates of type 2 diabetes and mental health problems than the general United States population. Few studies have explored the relationship other than detail the two issues independently. The present review aims to identify programs that seek to prevent/treat type 2 diabetes and mental health disorders in the American Indian and Alaska Native population. Available programs were reviewed for AI/AN adults and youth who suffer with both. As part of the review process, databases were searched for peer reviewed published studies. It was found that very few programs effectively incorporate …

Food Security Status And Life Events Among Households With Children In The Midlands Of South Carolina, Erin Rebekah Drucker

Theses and Dissertations

Purpose: Food insecurity is a major public health problem in the United States (US) with 14.5% of US households having experienced some level of food insecurity in 2012. Among households with children, 20% experienced low food security in 2012, and in half of these households, both the children and adults were affected. Food insecurity among children can have lifelong negative health and mental effects. Life events are defined as self-­‐reported life changes, which create a strain on resources and an opportunity for food insecurity, Methods: The Midlands Family Study (MFS) was a cross-­‐ sectional study that surveyed households …

Characterization Of Stard4 And Stard6 Proteins In Human Ovarian Tissue And Human Granulosa Cells And Cloning Of Human Stard4 Transcripts, Aisha Shaaban

Theses and Dissertations

Progesterone is essential hormone for pregnancy, which is produced by the human corpus luteum in early pregnancy until the placenta assumes this function. Transport of the cholesterol from the outer to the inner mitochondrial membrane is the rate limiting step for the de novo synthesis of pregnenolone (the precursor to progesterone), a process mediated by STARD1. STARD1 contains a C-terminal lipid binding domain which binds cholesterol and an N-terminal domain targeting STARD1 to the mitochondrial membrane. Unlike STARD1, STARD4 and STARD6 proteins lack a mitochondrial targeting sequence; however, they can bind cholesterol and increase steroidogenesis in model systems. In this …

The Association Of Gender, Age, And Coping With Internalizing Symptoms In Youth With Sickle Cell Disease, Laura Reinman

Theses and Dissertations

Youth with sickle cell disease (SCD) are at an elevated risk for having internalizing symptoms. Prior studies have suggested unique age by gender patterns of internalizing symptoms may be present in this population, however this pattern has not been thoroughly examined and the mechanisms underlying this pattern are not known. We examined rates of depression and anxiety symptoms between males and females with SCD across childhood and into adolescence in a cross-sectional design. We also considered the potential role of coping styles and health related locus of control for SCD morbidity that could account for age or gender patterns for …

Maternal Obesity, Gestational Weight Gain And Offspring’S Asthma, Kristen Polinski

Theses and Dissertations

Introduction: Obesity is common among women of childbearing age and intrauterine exposures may influence the development of early childhood asthma. A handful of studies have investigated pre-pregnancy obesity, but even fewer have thoroughly explored gestational weight gain as possible childhood asthma risk factors. Gaps remain in the literature and to our knowledge, none have longitudinally explored these relationships in a nationally representative sample of U.S. children.

Methods: We used data from the Early Childhood Longitudinal Study – Birth Cohort, in which children were followed through age four (n≈5,200). Asthma was based on parent report of a physician’s diagnosis. …

The Role Of Effortful Control And Cortisol In The Emergence Of Adhd, Asd, And Anxiety In Boys With Fxs, Marissa L. Robinson

Theses and Dissertations

ADHD, ASD, and anxiety are three of the most common co-occurring disorders in children with FXS leading to increased social, academic, and behavioral difficulties (Bailey, Raspa, Olmsted, & Holiday, 2008). Early identification and treatment of these co-occurring mental health disorders is essential to promote optimal outcomes; therefore, the study of early precursors and underlying mechanisms of these disorders within a developmental framework is warranted. The current dissertation includes two sequential and related studies investigating impaired effortful control as a precursor and HPA axis dysfunction (measured through salivary cortisol) as an underlying mechanism to the emergence of ADHD, ASD, and anxiety …

The Interplay Between Personality And Structure: How Do Actors With Differing Social Values Behave In Economic Exchange?, Patricia Danielle Lewis

Theses and Dissertations

This dissertation integrates Network Exchange Theory (NET) with Social Value Orientations (SVO) literature. Previous SVO research has consistently found strong differences between prosocial and proself actors in social dilemmas and similar settings. That research has not, however, examined the behavior of actors engaging in negotiated exchange. Willer, Gladstone, and Berigan (2013) derived metric predictions for embedding actors of differing social values within exchange structures. I followed their work by testing these predictions in laboratory experiments using three types of exchange structures. While the predictions anticipated strong differences in earnings between orientation types, the results suggested otherwise. The earnings of prosocials …

Interpregnancy Weight Change And Adverse Maternal Outcomes, Chelsea Lynes

Theses and Dissertations

Obesity during pregnancy is associated with a high risk of adverse maternal outcomes. Little is known about how weight change between consecutive pregnancies impacts subsequent pregnancy complications and newborn outcomes. This study aimed to explore the association between interpregnancy BMI change and adverse maternal outcomes, specifically, gestational diabetes mellitus (GDM), gestational hypertension, pre-eclampsia, non-repeat cesarean delivery (C-section), and vaginal birth after cesarean delivery (VBAC). The study sample was derived from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Consecutive Pregnancy Study, which collected data from 20 hospitals in Utah utilizing electronic medical records and International Classification …

Modeling And Computations Of Cellular Dynamics Using Complex-Fluid Models, Jia Zhao

Theses and Dissertations

Cells are fundamental units in all living organisms as all living organisms are made up of cells of different varieties. The study of cells is therefore an essential part of research in life science. Cells can be classified into two basic types: prokaryotic cells and eukaryotic cells. One typical organisms of prokaryotes is bacterium. And eukaryotes mainly consist of animal cells. In this thesis, we focus on developing predictive models mathematically to study bacteria colonies and animal cell mitotic dynamics.

Instead of living alone, bacteria usually survive in a biofilm, which is a microorganism where bacteria stick together by extracellular …

A Comparison Of The Factor Structure Of The Short Form Liberal Feminist Attitude And Ideology Scale (Lfais) For Women And Men In A University Survey, V. Diane Woodbrown

Theses and Dissertations

The current study compares the factor structure of the short form Liberal Feminist Attitude and Ideology Scale (LFAIS; Morgan, 1996) for males and females in a University survey. We first provide a discussion of feminism, a brief narrative review summarizing previous and co-existing measures of the construct “feminist attitudes” for males and females, and then conduct confirmatory factor analyses (CFA) and exploratory structural equation modeling (ESEM) to test Morgan’s own theory that there may exist a single general factor underlying the Liberal Feminist Attitudes Ideology Scale for males and for females, and that the latent construct/s underlying this scale are …

The Role Of Self-Efficacy In Mediating The Effect Of Physical Activity On Adolescent Depression, Nevelyn N. Trumpeter

Theses and Dissertations

Depression is a common psychiatric problem experienced in adolescence with nearly a quarter of all adolescents experiencing a major depressive episode before adulthood. Previous evidence indicates that physical activity (PA) is a known protective factor for depressive symptoms and major depressive disorder in adolescents and that PA self-efficacy (i.e., self-confidence) improves self-esteem, which in turn reduces depressive symptoms. Furthermore, PA self-efficacy may be more protective against depression for individuals who value or consider PA to be highly important. The proposed study aimed to determine the cross-sectional and longitudinal PA-depressive symptoms relation in adolescents. The study was designed specifically to test …

Tipping The Balance Of Double-Strand Break Repair In Cells Modeling Hutchinson-Gilford Progeria Syndrome, Andrew Robert Patrick

Theses and Dissertations

Hutchinson-Gilford Progeria Syndrome is disease of highly accelerated aging. In addition to appearing physically old mere months after birth, patients suffer from maladies typical of the elderly, including heart attack and stroke, two factors which contribute to an average life expectancy of 14 years. The source of progeria has been identified as progerin, a defective variant of nuclear lamina protein lamin A. Progerin has also been found natively in healthy cells (concentration increasing with age), and is known to adversely affect nuclear morphology and chromosomal integrity. This thesis sought to investigate the effect of progerin upon which pathways were favored …

Characterization Of The Sufc Atpase During Fe-S Cluster Assembly By The Suf Pathway In Escherichia Coli, Khaleh Mykel Thomas

Theses and Dissertations

The gram-negative bacterium E. coli encodes the Suf pathway to assemble iron-sulfur (Fe-S) clusters under iron starvation and oxidative stress conditions. The ATPase activity of SufC is critical for in vivo Fe-S cluster assembly by the Suf pathway. SufC shares homology with the nucleotide binding domain (NBD) of ATP-binding cassette (ABC) transporters and belongs to the AAA+ (ATPases Associated with diverse cellular Activities) ATPase superfamily, a family of proteins that utilizes energy from ATP hydrolysis to perform a variety of cellular functions. SufC forms a stable SufBC2D complex with partner proteins SufB and SufD. The SufBC2D complex serves as a …

The Fancy Trade And The Commodification Of Rape In The Sexual Economy Of 19th Century U.S. Slavery, Tiye A. Gordon

Theses and Dissertations

The purpose of this research is to examine the Fancy Trade—the buying and selling of mixed-race enslaved women for the primary purpose of prostitution and concubinage—through an intersectionality lens. Therefore, I will explore a culture of rape through the lived experiences of fancy maids, the women who were sold as sex commodities in the 19th century domestic slave trade. Who was she? Using an intersectionality framework to answer the proposed questions will achieve the following. First, it will highlight the social constructions of race, gender, and sexuality within the 19th century southern context. Secondly, an intersectional methodology will explore the …

Engineered 3d Microenvironments To Direct Osteogenic Differentiation And Modulate Inflammation, Katherine Elizabeth Rutledge

Theses and Dissertations

Current methods of treating critical size bone defects (CSDs) include autografts and allografts, however both present major limitations including donor-site morbidity, risk of disease transmission, and immune-rejection. Tissue engineering provides a promising alternative to circumvent these shortcomings through the use of stem cells, three dimensional (3D) scaffolds, and growth factors. Cells receive signals from their microenvironment that determine cell phenotype, and a combination of physical cues and chemical factors is thought to have the most profound influence on stem cell behavior. A major focus of tissue engineering strategies is scaffold design to recapitulate in vivo microenvironmental architecture to direct stem …

The Effects Of Environmental Consciousness And Menu Information On Consumers’ Perceptions Of Restaurant Image And Purchase Behavior Related To Local Foods, Daniel A.G. Remar

Theses and Dissertations

Sustainability initiatives have become increasingly important and relevant to the foodservice industry. Despite the fact that consumer demand for sustainable restaurant practices has grown substantially over the last 10 years, consumers’ pro-environmental attitudes and behavioral intentions are not always turned into concordant behavior. Though foodservice operators continue to make progress in developing new methods and strategies for implementing sustainable practices into operations, getting consumers to behave in accordance with their demand is a major challenge.

The purpose of this quasi-experimental study is to determine if consumers’ attitudes towards local food, widely considered a sustainable restaurant practice, are congruous with their …
