The Acute Effect Of Propanil On Reproductive Hormones, Ovarian Gene Expression And Splenic Cells In C57bl/6 Female Mice, Malia Danielle Berg

Graduate Theses, Dissertations, and Problem Reports (ETD)

Earlier evidence indicates exposure to propanil, a post-emergent herbicide used on rice and wheat fields, increases the number of antibody-secreting cells (ASC) in the spleen of mice after immunization with heat-killed Streptococcus pneumoniae (HKSP, 2x10⁸ CFU). Interestingly, an intact hypothalamic-pituitary-gonadal (HPG) axis is required for this immune response assessed on day 7-10 after immunization in female mice. Hence, an overarching premise is that propanil arbitrates the connection between the reproductive and immune system by altering the concentration of hormones involved in the HPG axis, which may then affect the populations of splenic cells. Hypotheses were tested with C57Bl/6 female …

Three Essays On Water Economics, Fahad Alzahrani

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation consists of three essays that explore the impacts of changes in public water quality, reliability, and raw water source. The first essay explores the relationship between episodes of contaminated drinking water and health care expenditures in the United States. Using panel data from 48 contiguous states from 2000 to 2011 and spatial econometrics modeling methods, the results indicate that there is positive and statistically significant impact on per capita health care expenditures from the percentage of a state’s population exposed to contamination episodes. The second essay examines the problem of water supply reliability due to aging infrastructure of …

Evaluating The Consistency Of A Breathing Flow Recording Device Across Different Elastomeric Half-Mask Respirators, Samuel Jennings Munnis

Graduate Theses, Dissertations, and Problem Reports (ETD)

The National Institute of Occupational Safety and Health (NIOSH) is the organization in charge of approving respiratory devices in the United States, as permitted by 42 CFR Part 84. Standards that NIOSH uses to certify powered air-purifying respirators (PAPRs) are based on respiratory data collected before the 21^st century. With new technologies, it is possible to gain a more accurate understanding of breathing flow of healthcare workers (HCWs). A new portable breathing flow recording device developed by The S.E.A. Group was intended for use with a Sundström SR100 mask with a P100 filter. This study tests the device with …

Promoting Cognitive And Fine Motor Development In The Art Room For Young Students With Exposure To Trauma: An Exploratory Case Study., Tiffany Marie Minuci

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite the overwhelming research that suggests visual artmaking experiences can produce positive outcomes for individuals, many state art education policies fail to implement and integrate the arts into core academic curriculums. Specifically in the state of West Virginia, kindergarten through twelfth grade students often lack the access to a quality and consistent art education. With high teacher-pupil ratios and inclusive learning environments, educators face the difficult task of meeting all the individual needs of their students’ in the classroom. This not only affects whole student populations, but also poses risks for children who have been exposed to trauma. Traumatic experiences …

Enabling Robust State Estimation Through Covariance Adaptation, Ryan Magnum Watson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Several robust state estimation frameworks have been proposed over the previous decades. Underpinning all of these robust frameworks is one dubious assumption. Specifically, the assumption that an accurate a priori measurement uncertainty model can be provided. As systems become more autonomous, this assumption becomes less valid (i.e., as systems start operating in novel environments, there is no guarantee that the assumed a priori measurement uncertainty model characterizes the sensors current observation uncertainty).

In an attempt to relax this assumption, a novel robust state estimation framework is proposed. The proposed framework enables robust state estimation through the iterative adaptation of the …

Morphological And Phylogenetic Resolution Of Diplodia Spp., Emerging Canker Pathogens Of Oak (Quercus Spp.), In The United States, Savannah Lyn Ferreira

Graduate Theses, Dissertations, and Problem Reports (ETD)

In Mediterranean Europe and the United States, oak species (Quercus spp.) have been in a state of declining health and vigor for the past several decades. Several biotic agents have been found to contribute to this decline to varying degrees including Phytophthora cinnamomi and Armillaria spp., both causal agents of root rots, and various insect defoliators. In the U.S., Bretziella fagacearum, the causal agent of oak wilt, has also been implicated. More recently, Diplodia corticola (Dc) and other Diplodia spp. have been implicated in causing dieback and mortality of oak species in Europe and in …

Identity Formation Of Adolescents Who Are Homeschooled: Mothers' Perceptions, Peggy Joan Mcqueen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Homeschooling is a growing educational choice with very little research about the psycho-social outcomes associated with the process. This qualitative study sought to examine the potential facilitative benefit of homeschooling upon the formation of identity. The participants were 26 mothers of homeschooled adolescents in Pennsylvania. Parent responses were examined using thematic analysis. Constituent aspects of parental motivation and methodology were investigated to assess the presence of elements facilitative in the process of identity formation as identified by Erik Erikson (1959, 1963). In examining methods used in homeschooling, it was found that the mothers in this study are providing the support …

Multidimensional Analysis Of Vulnerability: Methodological Advances And A Case Study From Malawi., Park Mcmillan Muhonda

Graduate Theses, Dissertations, and Problem Reports (ETD)

Since 1990s rural households in Malawi, constituting 85% of the population, have experienced deepening livelihood vulnerability, often manifested as persistent food insecurity. Livelihood crises have since been blamed on or attributed directly to weather perturbations/climatic shocks i.e. El-Nino induced climate variability/drought conditions. This study revealed that persistent livelihood crisis in rural Malawi cannot be attributed to or squarely blamed on weather shocks alone, rather it is at the intersection of various livelihoods shocks that rural livelihood vulnerability in Malawi is exacerbated i.e. worsening and deepening.

Thus, rural livelihood vulnerability to climate shocks in Malawi is manifest not in isolation but …

Population Health Of Spotted Salamanders (Ambystoma Maculatum) In Created Vernal Pools: An Integrative Approach, Alice R. Millikin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Habitat creation is an important tool for conservation to counteract habitat loss and degradation. Vernal pools are susceptible to destruction due to limited detection, protection, and regulation. These wetlands provide fishless breeding habitat for many amphibian species including spotted salamanders (Ambystoma maculatum) in eastern North America. Determining whether created vernal pool habitat is successful is often determined by demographic data of colonizing populations. I suggest that hormone levels, population genetics, and disease prevalence can improve our understanding of population health in created habitat. The goal of this dissertation was to assess the health of spotted salamander larvae in …

Behavioral Impairment Following Gestational Exposure To Titanium Dioxide Nanomaterial Aerosols In Male And Female Rats, Matthew Leland Eckard

Graduate Theses, Dissertations, and Problem Reports (ETD)

Engineered nanomaterials (ENMs) are beginning to be recognized as hazardous to human and animal health. Titanium dioxide (TiO2) is primarily used as a whitening agent in paints, plastics, and sunscreens. While relatively inert in its bulk form, nano-TiO2 (diameter) can produce prolonged inflammation and oxidative stress in target tissue. Recently, the potential for nano-TiO2 to cause neuroinflammation and damage has heightened concerns about its continued use. One important concern is that nano-TiO2, and other metal oxide ENMs, may affect fetal neurodevelopment. Accordingly, it is imperative to screen ENMs, like TiO2, for possible neurotoxicity following developmental exposures. The current set of …

Short-Term Abstinence Effects In Experienced Electronic Cigarette Users, Nicholas J. Felicione

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nicotine/tobacco dependence is a problem that negatively affects health at an individual and population level. Nicotine/tobacco dependence may be best assessed by measuring withdrawal symptoms of a nicotine/tobacco user who abstains from use. Withdrawal symptoms experienced by cigarette smokers are well characterized, including deficits in attention and memory, as well as self-reported cravings, urges, and other symptoms. While withdrawal in cigarette smokers has been studied extensively, little is known about dependence and withdrawal associated with newer products, such as electronic cigarettes (ECIGs). ECIGs can deliver nicotine comparably to tobacco cigarettes, indicating that they may have the potential to cause dependence. …

A Rare Presentation Of Cardiac Aspergilloma In An Immunocompetent Host: Case Report And Literature Review, Abdullah M. Pervaiz, Salman A. Bangash, Raheel Akhtar, Zain Wahab, Hyder Bangash

School of Medicine Publications

Cardiac aspergilloma is exceptionally rare with only a handful of cases reported and majority of them being in immunocompromised patients. Here, we present a case of cardiac aspergilloma involving the right and left ventricle in an immunocompetent patient that initially presented with acute limb ischemia. He was later found to have a cardiac mass with histopathological diagnosis confirming Aspergillus species. Despite aggressive medical and surgical interventions, the patient had an unfavorable outcome due to low suspicion of invasive fungal endocarditis given his immunocompetent status. Cardiac aspergilloma should remain in the differential diagnosis of immunocompetent patients as early clinical suspicion will …

The Effect Of Communication And Vehicle Properties On The Search Performance Of A Swarm Of Unmanned Aerial Vehicles, Jenna E. Newcomb, Andrew Ning

Faculty Publications

An unmanned aerial vehicle (UAV) swarm allows for a more time-efficient method of searching a specified area than a single UAV or piloted plane. There are a variety of factors that affect how well an area is surveyed. We specifically analyzed the effect both vehicle properties and communication had on the swarm search performance. We used non-dimensionalization to examine the effect vehicle properties had on search performance so the results can be applied to any domain size with any number and type of vehicle. We found that even if vehicles could only sense 10% of the grid area at any …

Alternative Splicing In Vertebrate Photoreceptors And Mechanisms Underlying Retinitis Pigmentosa, Jesse C. Sundar

Graduate Theses, Dissertations, and Problem Reports (ETD)

RNA binding proteins (RBPs) have emerged as important regulators of gene expression. RBPs typically contain RNA binding domains that recognize a specific sequence and/or structural motifs within the RNA. This allows them to modulate metabolism of RNAs in several possible ways including regulation of alternative splicing and processing, polyadenylation, translocation, localization, modification, stability, or translation. Previous studies have shown the Musashi (MSI) RBP family to be highly expressed in the retina, and more specifically, photoreceptors, but the importance of this expression remains largely unknown. We identified the MSI proteins as potential regulators of alternative exon splicing in murine photoreceptors. We …

School of Medicine Publications

The MS is prevalent in Mexican Americans (MAs) and is projected to increase. It is important therefore to better understand its genetic and environmental determinants. We hypothesized that the MS reflects dysfunction in important biological systems. To evaluate this concept, we analyzed gene expression data for the adaptive-immune, innate-immune, and hemostasis systems in relation to the MS from a study on MAs of San Antonio and the Rio Grande Valley.

Beyond English Only: Addressing Language Interpretation In Professional Psychology Training, Timothy B. Smith, Clay A. Frandsen, Derek Griner, Domenech Rodriguez, Guillermo Bernal

Faculty Publications

Professional guidelines direct that psychologists working with clients with limited English proficiency should involve an interpreter if a mental health professional fluent in the client’s language is unavailable. However, complexities of interpreted therapy require training. We describe nine relevant areas of trainee skill acquisition and also surveyed 102 multicultural course instructors in APA-accredited psychology programs regarding current professional training. Only 55 (54%) instructors reported providing any training on working with language interpreters, with 16 (16%) providing more than 2 hours of training. Instructors ranked nine proposed skill areas and gave recommendations for over coming barriers and working with interpreters to …

Integration Or Separation? Addressing Religious And Spiritual Issues In Multicultural Counseling: A National Survey Of College Counselors, Timothy B. Smith, Rachel Crook Lyon, Kari O'Grady

Faculty Publications

Given contemporary ethical concerns, we conducted a national survey of 216 college counselors’ perceptions of integrating religious and spiritual issues in multicultural counseling and counselor education. Using cluster analysis, we identified four patterns of commitments to multiculturalism and religiosity. Respondents demonstrated ethical bracketing, as they considered religious and spiritual issues favorably within the framework of multicultural counseling, irrespective of their personal commitments to those topics. Counselors can openly address spiritual and religious diversity.

Changes in CACREP standards and DSM-5 diagnoses reflect the need to train counselors in the screening and treatment of behavioral/process additions (BPAs). This guide presents foundational issues counselor educators and supervisors may consider when developing an addictions course inclusive of BPAs. It also highlights components of a sample syllabus for a BPA course, including student learning outcomes (SLOs), course topics, materials, and activities/assignments. Developing curricula inclusive of BPAs is a way for counselor educators to begin to advocate for comprehensive addictions curricula within existing counselor education programs, in order to improve the competency of the counselors they train.

'I Think I'M Gonna Hurl': A Narrative Review Of The Causes Of Nausea And Vomiting In Sport, Patrick B. Wilson

Counseling & Human Services Faculty Publications

Exercise-associated gastrointestinal (GI) distress can negatively impact athletic performance and interfere with exercise training. Although there are a few universal underlying causes of GI distress, each symptom often has its own unique triggers and, therefore, its own prevention and management strategies. One of the most troubling GI symptoms an athlete can experience during training and competition is nausea/vomiting. The prevalence of nausea varies with several factors, two of the most important being exercise intensity and duration. Relatively brief, high-intensity exercise (e.g., sprinting, tempo runs) and ultra-endurance exercise are both associated with more frequent and severe nausea. The potential causes of …
