The Human–Hookworm Assemblage: Contingency And The Practice Of Helminthic Therapy, Sophia Anne Strosberg

Theses and Dissertations--Geography

Through a qualitative analysis of the use of intestinal parasites for treating immune system disorders, this research illustrates how contingency emerges in the context of the human relationship to hookworms. The affect of the human–nonhuman relationship is an important part of understanding the direction of evolutionary medicine today, and has implications for the politics of biological health innovations. The shift from the bad parasite to a parasite that at least sometimes heals, discursively and materially, has opened new spaces for patients to change the way they relate to medical knowledge, medical professionals, and pharmaceutical companies. Hookworms are banned by the …

Rooted in the theories of urban entrepreneurialism, this dissertation employs a political economy framework as a means of analyzing urban governance and economic development in the contemporary US city. This case study of Orlando adds to our understanding of how entrepreneurial narratives are being applied to transportation infrastructure projects in pursuit of local economic development.

The empirical case study explores the relationship between planning narratives, urban governance and economic development in the establishment of the SunRail commuter rail system in central Florida. I present the political history of economic development and the role of local boosters in shaping the sociospatial …

Carbon Forestry: Pursuing Climate Change Mitigation And Poverty Alleviation Through Market-Based Forest Carbon Schemes In Chiapas, Mexico, Jonathan Otto

Theses and Dissertations--Geography

Forest carbon projects seek to alleviate rural poverty and mitigate global climate change by facilitating the flow of capital from actors looking to offset CO2 emissions to land managers willing to engage in offset-oriented reforestation, afforestation, and forest preservation activities. In Mexico, forest carbon schemes have been pursued within the country’s national Payment for Ecosystem Services (PES) program, and through REDD+ pilot projects and separate voluntary initiatives. In this dissertation, I explore one voluntary project, Scolel’ Te, which is managed by the non-governmental organization (NGO), AMBIO. Focusing on the case of Scolel’ Te, I show how forest carbon projects undermine …

Pretreatment Of Scenedesmus Sp. Biomass As A Potential Anaerobic Digestion Substrate, Xinyi E, Czarena Crofcheck

Biosystems and Agricultural Engineering Faculty Publications

Algal biomass can be a potential substrate for anaerobic digestion. However, raw algae cells show a resistance to biological degradation, resulting in a slower methane production rate. Varying thermal and chemical pretreatments of algal biomass were investigated in an attempt to increase soluble organic matter (SOM) yield, which would result in enhanced methane production during subsequent anaerobic digestion. Scenedesmus sp. was harvested using three different procedures: with flocculation, with flocculation and drying, and without flocculation or drying. For all pretreatments and algae types, fluorescence micrographs were obtained to visually confirm the degradation of the algal cell walls. A complete 2 …

Report of Investigations--KGS

A carbon dioxide injection test well was drilled in 2009 to a depth of 8,126 ft below ground surface in Hancock County, Kentucky. Six hundred ninety tons of CO₂ was successfully injected into Knox Group saline aquifers. Two domestic wells (MB and GB) and two domestic springs (CA and RC) were sampled to monitor any potential changes in groundwater quality associated with possible migration of CO₂ from deeper saline aquifers into shallow freshwater aquifers. The four sites were sampled for pH, bicarbonate, total dissolved solids, turbidity, anions, total dissolved metals, dissolved inorganic carbon, total CO₂, and …

Associations Of Maternal Socio-Demographic And Psychosocial Characteristics With Alcohol Use During Pregnancy, Nneoma Adaobi Ilogu

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Alcohol is reported to be one of the most used legal substances among women of reproductive age, and its use during pregnancy is one of the most preventable causes of birth defects and developmental disabilities.1 Due to its teratogenic nature, alcohol use during pregnancy has been associated with a condition referred to as Fetal Alcohol Spectrum Disorders (FASD).2 This comprises of a wide spectrum of disorders such as Fetal Alcohol Syndrome (FAS), alcohol-related birth defects, and alcohol-related neurodevelopmental disorders, which are estimated to affect 1% of all births in the United States and can be prevented through the modification of …

Are There Benefits Of Smoking Reduction During Pregnancy? Smoking Status Of Pregnant Women And The Effect On Pre-Term Delivery, Kelli Ann Mclane

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Premature delivery is defined as a baby born before thirty-­‐seven completed weeks of pregnancy. Premature delivery can result in a longer hospital stay after delivery compared to babies born at full-­‐term.1 Babies born before 37 gestational weeks also have a greater potential for health problems such as acute respiratory, gastrointestinal, immunologic, central nervous system, hearing, and vision problems, as well as longer-­‐term motor, cognitive, visual, hearing, behavioral, social-­‐emotional, health, and growth problems.2 Premature births can impact at the individual level and at a societal level. “The birth of a preterm infant can bring considerable emotional and economic costs to families …

Factors Affecting School Health Scores: Wellsat Scores, School Policy, And The School Environment, Alicia Baker

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

A recent trend in school health intervention has been through policy creation and development. Studies have shown that changes in school health policy can improve student health behaviors, particularly in physical activity and nutrition. This study looked at how potential factors could affect the scores of a school policy assessment tool called the Wellness School Assessment Tool (WellSAT). Using a combination of t-tests, chi-square tests, and logistic regression, schools’ strength and comprehensiveness nutrition scores from the WellSAT were analyzed when compared to Free and Reduced Lunch Rates, type of school, and whether schools had separate policies from their school district. …

Effects Of Locality And Risk Of Late Stage Breast Cancer Diagnosis In Kentucky Females, 2001-2011, Michael Jacob Sither

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Breast cancer survival is heavily dependent on stage at diagnosis. Recent evidence supports rural women are more likely than urban women to be diagnosed with advanced stage disease but historically these findings have been mixed when investigated at the state level. Cancer surveillance in the Appalachian region suggests Kentucky females are at significantly greater risk of premature breast cancer mortality due to consistently lower prevalence of screening mammography utilization. In the literature, disparities in breast cancer outcomes have been largely explained by population demographics, areabased measures of socioeconomic deprivation, shortages of referring providers as well as differences in spatial access …

Evaluating Oral Health Trends In Kentucky, 2006-2012, Briana Michelle Forsythe

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

According to the former US Surgeon General, C. Everett Koop, “You’re not healthy without good oral health.” Poor oral health, comprising of the presence of caries and/or periodontal disease, can lead to edentulism, which in turn can yield poor physical health, inability to communicate properly, poor mental health, and a lesser quality of life. In Kentucky, over one quarter of the adult population has lost six or more teeth due to decay or gum disease, a figure 10% higher than the national average. Objectives: The purpose of this study was to examine: a) Kentucky’s Statewide Oral Health Strategic Plan, implemented …

Factors Influencing Differential Oral Health Care Use Between Hispanics And Non-Hispanic Whites In The U.S., Nathalie Astudillo

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Oral health is often considered merely the absence of disease. However, oral health involves much more. Good oral health facilitates very basic functions like eating and speaking; a healthy smile is also associated with good self-esteem and productivity.1 Most oral health diseases are largely preventable. Despite this, a large portion of the population in the United States still suffer from untreated dental decay.2 Poor oral health has a direct effect on systemic health, quality of nutrition, digestion, phonetics, selfimage and self-esteem.5 Whether considered individually or combined, each of these factors has a direct impact on the quality of life of …

Play In Children With Motor Disabilities, Suzanne Martin

Theses and Dissertations--Rehabilitation Sciences

The purpose of this research was to explore and describe the relationship among the child, family, home environment, and pretend play of children with motor disabilities. The environment is a powerful force in early child development. This research is based on Bronfennbrenner’s ecological theory of development and the ubiquitous role of play in all domains of development. Children with motor disabilities may lack exploration of the environment and as a consequence demonstrate deficits in play. Play was measured in 32 children with motor disabilities aged 24.8 to 61.3 months with a mean age of 33.7 (SD 9.3) months. Children demonstrated …

Earthquake Risk In Indonesia: Parametric Contingent Claims For Humanitarian Response And Financial Institution Resiliency, Jason Hartell

Theses and Dissertations--Agricultural Economics

This dissertation explores the use of an index based contingent claims mechanism against earthquake risk in Indonesia. It focuses on time critical financing needs of international humanitarian relief organizations, and on efforts to improve the resiliency of geographically constrained financial institutions whose clientele are exposed to disaster risk. The approach uses measures of ground motion intensity as the basis for the index. The humanitarian response mechanism provides a new way for private sector partners to participate and gain visibility in their support of principled humanitarian funding. Index based contingent claims for local banks are shown to enhance their ability to …

Food Imports Under Foreign Exchange Constraints In The Cfa’S Franc Zone Of Sub-Saharan Africa (Ssa), Seydina Ousmane Sene

Theses and Dissertations--Agricultural Economics

To respond to the high imported food prices in their domestic markets, net food importing countries in the Communauté Financière Africaine (CFA) zone^[1] are adjusting their import tariffs and homologate domestic prices of imported commodities such as rice, wheat, maize, and sugar. This research uses a multivariate specification of error correction model (VECM) of estimation to investigate the link between food imports, world price index of rice, wheat, maize and sugar, real effective exchange rates, domestic food production, GDP, and trade openness in the short and long run. The data are on each homogenous commodity from 1969 to 2012. …

Effects Of Sodium Hydroxide Pretreatment On Structural Components Of Biomass, Alicia A. Modenbach, Sue E. Nokes

Biosystems and Agricultural Engineering Faculty Publications

Pretreatment is a unit operation in the conversion of biomass to valuable products that utilizes various combinations of conditions, including chemicals, heat, pressure, and time, to reduce the recalcitrance of lignocellulose. Many such pretreatments have been developed over the years, as the operating conditions can be adapted so that lignocellulose is modified in ways unique to each pretreatment. By tailoring pretreatment conditions to achieve these modifications, the types of final products produced can be controlled. The purpose of this review is to provide a consolidated source of information for sodium hydroxide effects on lignocellulose. The structural characteristics of lignocellulose and …

Strand Exchange Of Telomeric Dna Catalyzed By The Werner Syndrome Protein (Wrn) Is Specifically Stimulated By Trf2, Deanna Edwards, David K. Orren, Amrita Machwe

Toxicology and Cancer Biology Faculty Publications

Werner syndrome (WS), caused by loss of function of the RecQ helicase WRN, is a hereditary disease characterized by premature aging and elevated cancer incidence. WRN has DNA binding, exonuclease, ATPase, helicase and strand annealing activities, suggesting possible roles in recombination-related processes. Evidence indicates that WRN deficiency causes telomeric abnormalities that likely underlie early onset of aging phenotypes in WS. Furthermore, TRF2, a protein essential for telomere protection, interacts with WRN and influences its basic helicase and exonuclease activities. However, these studies provided little insight into WRN's specific function at telomeres. Here, we explored the possibility that WRN and TRF2 …

Psychology Faculty Publications

Nicotine dependence plays a critical role in addiction to tobacco products, and thus contributes to a variety of devastating tobacco-related diseases (SGR 2014). Annual costs associated with smoking in the US are estimated to be between $289 and $333 billion. Effective interventions for nicotine dependence, especially in smokers, are a critical barrier to the eradication of tobacco-related diseases. This overview highlights research presented at the Plenary Symposium of Behavior, Biology and Chemistry: Translational Research in Addiction Conference (BBC), hosted by the UT Health Science Center San Antonio, on March 9–10, 2013. The Plenary Symposium focused on tobacco addiction, and covered …

Enhancing The Care Navigation Model: Potential Roles For Health Sciences Librarians, Jeffrey T. Huber, Robert M. Shapiro Ii, Heather J. Burke, Aaron Palmer

Information Science Faculty Publications

This study analyzed the overlap between roles and activities that health care navigators perform and competencies identified by the Medical Library Association's (MLA's) educational policy statement. Roles and activities that health care navigators perform were gleaned from published literature. Once common roles and activities that health care navigators perform were identified, MLA competencies were mapped against those roles and activities to identify areas of overlap. The greatest extent of correspondence occurred in patient empowerment and support. Further research is warranted to determine the extent to which health sciences librarians might assume responsibility for roles and activities that health care navigators …

Children, Adolescents And Firesetting, Joav Merrick, Carrie Howell Bowling, Hatim A. Omar

Pediatrics Faculty Publications

The research of firesetting has been conducted in different ways and lacks a coherent, consistent and comprehensive set of empirical findings. A recent review concluded that despite a number of risk factors being repeatedly identified, an understanding of the etiology behind firesetting behavior and potential developmental trajectories remains theoretically rather than empirically based. Existing theories do not take sufficient account of the complexities of firesetting behavior and there is not yet a typology and accompanying assessment that has undergone thorough empirical testing and is of significant clinical utility. Due to the relationship between firesetting and antisocial behavior there is a …

Firesetting, Sexual Abuse And Long-Term Consequences, Lesley Davidson, Hatim A. Omar

Pediatrics Faculty Publications

In this chapter we summarize the limited studies on post-pubertal consequences of female childhood sexual abuse that includes both psychological distress and physiological stress. The characteristics of sexual abuse are discussed and determined to play a major role in the degree of trauma experienced and in the later effects. The concept of hormones and how disruptions in various endocrine systems can affect the development of these females are examined, especially during the pubertal period. Outcomes of interest included competence, in terms of cognitive, social, self-esteem, and locus of control, and psychopathology including depression, anxiety, dissociation, and hypersexuality. Direct physical results …

Firesetting Behavior And Psychiatric Disorders, Stephanie Stockburger, Hatim A. Omar

Pediatrics Faculty Publications

Firesetting behavior results in serious damage to lives and property every year. Firesetting has been linked to a number of comorbid psychiatric disorders including depression, substance abuse, conduct disorder, antisocial personality disorder, obsessive compulsive disorder, psychotic disorder, schizoid personality disorder, and schizophrenia. Psychiatric disorders differ by gender. In addition, juvenile firesetters have history of a separate set of psychiatric comorbidities. The strong correlation between psychiatric comorbidities and firesetting behavior illustrates the need for fire service and mental health collaboration.

Self-Reported Juvenile Firesetting, Carrie Howell Bowling, Hatim A. Omar

Pediatrics Faculty Publications

In this chapter we address gaps in existing research by examining the relationship between academic performance and attention problems with juvenile firesetting. Two datasets from the Achenbach System for Empirically Based Assessment (ASEBA) were used. The Factor Analysis Dataset (N = 975) was utilized and results indicated that adolescents who report lower academic performance are more likely to set fires. Additionally, adolescents who report a poor attitude toward school are even more likely to set fires. Logistic regressions were run to determine if attention problems predicted firesetting and the findings indicated that attention problems are predictive of self-reported firesetting. The …

Adolescent Bereavement, Leslie Robin, Hatim A. Omar

Pediatrics Faculty Publications

Depending on cognitive and emotional development, an adolescent may grieve very differently than a child or an adult. While mature enough to understand death's irreversibility, adolescents may not fully comprehend the enduring consequences of a loved one's death. As the desire to separate from their families and forge new intimate relationships with peers assumes increasing priority, adolescents can seem egocentric in their reaction to death, a response which often frustrates and perplexes adults. Because volatile behavior is characteristic of adolescence, health providers struggle to differentiate between normal and complicated bereavement. Here we review the commonly-accepted characteristics of normal and complicated …

United States: Sexual Behavior In Association With Human Papilloma Virus Vaccination In Young Girls, Wafa R.R. Al Romaih, Said Shahtahmasebi, Hatim A. Omar

Pediatrics Faculty Publications

The first human Papilloma virus (HPV) vaccine was approved in the United States in 2006 with the potential to reduce cervical cancer and genital warts. Since then, its efficacy in preventing HPV-related cancers in both males and females has been promising. Despite CDC recommendations, opponents of the vaccine assert that vaccinating preadolescents and adolescents will increase their sexual activity, as well as overtly condone risky sexual behavior. We analyzed clinic data of 499 adolescents with a mean age of 16 years to explore whether vaccination led to change in sexual behavior after one year. Our results showed no statistically significant …
