Examination Of The Time Course Effects Of Electronic Cigarettes On The Thoracic Aorta, Madison Robinson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Endothelial dysfunction is a critical early marker of the pathogenesis of cardiovascular disease and a pathological biomarker in cigarette smokers. Emerging evidence finds similar cardiovascular risks resulting from electronic cigarettes (E-cig) as that seen from smoking. Logically, the time or length of exposure to E-cigs will likely influence the development of vascular dysfunction, however, the length of exposure that causes permanent damage is unknown. The goal of this study was to determine the potential window of chronic E-cig exposure that results in vascular dysfunction, which is marked by endothelial dysfunction, microvascular dysfunction, and stiffening of arteries. Based on prior chronic …

Parental Socialization Of General And Domain-Specific Self-Control In Adolescents, Matty Johnston

Graduate Theses, Dissertations, and Problem Reports (ETD)

Adolescent self-control appears to be an important competency to develop. It has pervasive links with various outcomes (e.g., educational, financial, and interpersonal) both during adolescence and into adulthood (Allemand et al., 2019, Moffitt et al., 2011). Adolescents often report lower self-control compared to adults, although individual levels of self-control vary widely between adolescents (Allemand et al., 2019, Romer et al., 2010). Despite its importance, very little is known about how self-control develops. Thus, the current study aims to examine the relationship between parents’ self-control and that of their teen children. To further understand how adolescents' self-control may be socialized by …

Seeing Red: Hostile Attribution Bias, Aggression, And Antisocial Personality Disorder Traits, Kaley Potter

Graduate Theses, Dissertations, and Problem Reports (ETD)

Antisocial personality disorder (ASPD) is a destructive and severe mental illness that costs the U.S. trillions of dollars annually. Although ASPD is significantly correlated with acts of aggression, violence, and imprisonment, not all individuals with ASPD are aggressive. In samples without ASPD, increased aggression has been linked to an error in social information processing, which is referred to as hostile attribution bias (HAB).

The current study tested the extent to which HABs, or the tendency to attribute hostility to neutral or ambiguous stimuli, predicted aggression above and beyond ASPD traits in participants with a history of incarceration. Participants (N = …

Reimagining The Refugee Figure: Survival Migration And Its After-Affects, Gabriella Pishotti

Graduate Theses, Dissertations, and Problem Reports (ETD)

As the refugee crisis continues to worsen, so too will the field of refugee literature continue to expand into new directions to account for shifts in the refugee figure and developing concerns of survival migrant writers. Drawing from the foundational work of scholars such as Sianne Ngai and Sara Ahmed, I use affect theory as an intervention into these contemporary refugee texts to posit a rethinking of how we analyze refugee stories as narratives of crisis. I employ an affective approach to demonstrate how the emergency of forced migration can be narratively depicted in an embodied way that fosters connection …

Implementing Unmanned Aerial Vehicles To Collect Human Gait Data At Distance And Altitude For Identification And Re-Identification, Donn E. Bartram

Graduate Theses, Dissertations, and Problem Reports (ETD)

Gait patterns are a class of biometric information pertaining to the way a person moves and poses. Gait information is unique to each person and can be used to identify and reidentify people. Historically, this task has been achieved through the use of multiple ground-based imaging sensors. However, as Unmanned Aerial Vehicles (UAVs) advance, they present the opportunity to evolve the process of persons identification and re-identification. Collecting human gait data using UAVs at distances ranging from 20m to 500m and altitudes ranging from 0m to 120m is a challenging task. The current biometric data collection methods, primarily designed for …

Immune Outcomes Affected By Selection For Parasite Resistance In Katahdin Sheep, Kelsey Lynne Bentley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Our understanding of the complex connection between selection for parasite resistance and the overall health outcomes in livestock is unclear. This study investigates the impact of post-weaning fecal egg count (PFEC) estimated breeding values (EBV) on health outcomes and immune responses in Katahdin sheep. Selection for PFEC, favoring Low-PFEC lambs, not only affects survivability to weaning but also suggests broader implications for immunity beyond parasite resistance. The effect of PFEC EBV on antibody production in response to vaccination against Clostridium perfringens type C&D and tetanus toxoid (CD&T) revealed a stepwise decrease in immunoglobin (IgG) from Low-PFEC to High-PFEC groups upon …

Effectiveness Of Peer Support Groups For Mothers At Risk For Postpartum Depression, Natalie Paige Gates

Graduate Theses, Dissertations, and Problem Reports (ETD)

Motherhood requires a role transition, new maternal responsibilities, and changes in everyday life, which can impact the mother’s mental health, possibly leading to postpartum depression. Postpartum depression can, in turn, create additional challenges for the mother in engaging in her daily routines and occupations. Therefore, a peer support group for mothers at risk for postpartum depression was developed in hopes of improving the mothers’ management of routines, ultimately improving maternal mental health. The effectiveness of the peer support group was measured through quantitative and qualitative online self-report surveys, where the mothers reported their current mental health status, self-efficacy, and occupational …

Three Essays On Misinformation, Mistrust And Their Influence On Public Health Policy, Eli Kochersperger

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the first chapter I identify the impact of fentanyl exposure misinformation- namely, the erroneous belief that momentary, passive contact with the potent opioid fentanyl can be seriously harmful- on first responder behavior during overdose events, and on overall opioid-related mortality. I examine changes in opioid-related mortality following one particularly well-covered episode involving an Ohio police officer in 2017, wherein the officer appeared to experience an acute opioid overdose after touching what was believed to be fentanyl. Employing a synthetic differences-in-differences identification strategy, I find areas with greater media exposure to this misinformation exhibit marked increases in opioid overdose deaths; …

Analysis Of Mutations In Protein Kinase Ck2 Linked To Okur-Chung’S Neuropathy, Shivani Maan

Graduate Theses, Dissertations, and Problem Reports (ETD)

The studies described here focus on mutations in protein kinase CK2 linked to ‘Okur-Chung’s Neuropathy’ (OCN), a neurodevelopmental disorder that involves 10 distinct mutations in the catalytic subunit CK2α. It has, however, remained unresolved if these mutations impair CK2α activity or if they also impair association with the regulatory CK2β subunit, which is necessary for assembly of the α2β2 holoenzyme. I describe efforts to resolve these questions for two mutations, Y50S and D175G. The former is thought to reside at the CK2α-CK2β interface, whereas the latter is located proximal to the active site. I therefore hypothesized that Y50S should perturb …

The Impact Of Occupational Therapy In Lactation Services, Sarah Adrienne Mcaninch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Many benefits to breastfeeding exist for both mothers and infants, yet exclusive breastfeeding rates remain low across the nation. These benefits include decreased chance of infections for infants, low infant mortality, and decreased chances of breast and ovarian cancers for mothers (Binns et al., 2016; CDC, 2023). Education strategies have recently become imperative for health organizations to help mothers sustain their ability to breastfeed within the recommended six-month timeframe. Current literature on education supports that women who receive education at some point in their lactation journey are more likely to reach the six-month period and have more confidence in their …

Estradiol’S Role In Timely Puberty Onset In The Ewe, Eliana Gerardine Aerts

Graduate Theses, Dissertations, and Problem Reports (ETD)

In female sheep, the release of gonadotropin-releasing hormone (GnRH) from the hypothalamus triggers luteinizing hormone (LH) to be released from the pituitary. Luteinizing hormone, in turn, acts on the ovaries to elicit estradiol (E₂) release. E₂ acts in a negative feedback manner to control the amount of LH released. The increase in LH release that drives puberty onset results from a decrease in sensitivity to E₂ as the animal ages. However, the neural mechanisms mediating this change in sensitivity are not known, as is where in the hypothalamus E₂-negative feedback occurs. In the arcuate …

Using Critical Place-Based Pedagogy To Build A Bridge Between College Students’ Home Literacies And Their Academic Literacies In A Composition Class In West Virginia, Michael Vozniak

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation explores the use of place-based pedagogy as a tool for teaching for transfer in a college composition class in West Virginia. Although existing composition scholarship indicates that themed classes (such as a place-based class) are unlikely to facilitate transfer among the students, this is mostly due to instructors of themed classes not explicitly teaching for transfer. The literature suggests that the most effective way to facilitate transfer is to encourage students to reflect on how what they learned in one situation is similar to and different from what they need to learn in another situation. The aim of …

Estimate Of The Random Match Frequency Of Acquired Characteristics In A Forensic Footwear Database, Alyssa N. Smale

Graduate Theses, Dissertations, and Problem Reports (ETD)

When analyzing footwear impression evidence, one of the goals of an examiner is to determine if an exemplar shoe could be the source of an impression found at a crime scene. This opinion is based on an assessment of the similarity of class characteristics and randomly acquired characteristics (RACs) between the known and questioned impressions, as well as the rarity of the observed characteristics. The primary aim of this research was to estimate the random match frequency of randomly acquired characteristics (RAC-RMF) within a forensic footwear database to determine the frequency of RACs with geometric similarity occurring in the same …

Levantine Immigration And Community Building In Charleston, West Virginia, 1900-1930, George P. Jacobs Ii

Graduate Theses, Dissertations, and Problem Reports (ETD)

Immigrants from the Levant, a region of the middle east made up of Syria, Lebanon, Jordan, and Palestine, settled in the United States in large numbers between 1890 and 1920. Many eventually decided to make Charleston, West Virginia their permanent home. When they arrived in Charleston, most Levantine immigrants worked as peddlers, selling modern wares and household goods to families that needed them. This research explains the context for this immigration wave, the important economic niche Levantine immigrants satisfied in the developing economy of southern West Virginia, and how over time Charleston’s Levantine community contributed significantly to the city’s culture.

Attachment Issues: Microbes, Minerals, And The Persistence Of Soil Organic Matter, Md Shafiul Islam Rion

Graduate Theses, Dissertations, and Problem Reports (ETD)

The remnants of microorganisms are now understood to account for the majority of organic matter in many mineral soils. Despite the significance of this microbial necromass for soil carbon storage, we know relatively little about how the traits of microorganisms interact with soil minerals to determine the stability of microbe derived carbon in soil. Soil minerals differ in their surface area and chemistry potentially influencing microbial attachment, biofilm formation, and the persistence of microbial necromass. To address this knowledge gap, we grew twelve bacterial species from four broad groups of varying cell wall morphology (Gram positive, Gram negative, filamentous actinobacteria, …

Specialized Metabolism In Retina, Retinal Pigmented Epithelium, And Testis, Siyan Zhu

Graduate Theses, Dissertations, and Problem Reports (ETD)

The retina and its neighboring retinal pigmented epithelium (RPE) are high energy-demanding and metabolically active tissues with specialized and complementary metabolism. They are metabolically interdependent and impact each other’s viability. Interestingly, many of the metabolic features in the retina and RPE are shared with the testis. For example, testis is also energy costly due to continuous sperm differentiation and it has similar metabolic inter-dependence between different testis cells. Both the retina and testis are vulnerable to mitochondrial metabolic impairments.

We conducted three research projects to understand 1) the nutrient utilization and communication in retina and RPE; 2) The profiling of …
