Utilizing Plethodontid Occupancy To Assess Initial Ecosystem Responses To Invasive Plant Control Treatment In The Central Hardwoods, Maree Guinevere Dieterich

Graduate Theses, Dissertations, and Problem Reports (ETD)

Invasive plants are a growing concern for land managers, impacting ecosystem resilience and outcompeting native vegetation. To combat this, invasive plant control treatments can assist in reducing the impacts and spread of damaging, non-native plant species. However, intensive treatments completed at large scales have the potential to negatively impact ecosystem services as well. To monitor these impacts, I utilized a well-known indicator in the Central Applachian region, Plethodontid salamanders, to assess impacts of invasive plant control treatments in the Central Hardwood forests. I completed 12 visual samples across 60 sites in West Virginia, USA during Spring and Fall of 2025 …

Survival, Cause-Specific Mortality, Resource Selection, Movement Rates, And Population Dynamics Of White-Tailed Deer (Odocoileus Virginianus) In West Virginia, Usa, Brett P. Skelly

Graduate Theses, Dissertations, and Problem Reports (ETD)

White-tailed deer (Odocoileus virginianus) are one of the most culturally and economically important big game species in the United States. At the turn of the 20th century white-tailed deer were almost extirpated due to market hunting and unsustainable forestry practices that destroyed habitat. The creation of game laws that eliminated market hunting and created seasons and bag limits for deer hunting along with restocking efforts by sportsmen’s groups and state wildlife agencies aided in deer population recovery. These efforts have led to the abundant deer populations that are currently enjoyed by hunters and wildlife viewers. Deer populations require …

The Hidden Costs Of Consumption: A Multi-Context Investigation On Stigma And Social Judgment, Siti Nuraisyah Suwanda

Graduate Theses, Dissertations, and Problem Reports (ETD)

Consumption is not always as simple as an exchange of value between a buyer and a seller. In many contexts, what individuals choose to consume or not consume can carry social meaning, leading to judgment and devaluation. While prior research has explored stigma broadly in marketing and consumer behavior, less attention has been given to stigma that caused specifically by consumption choices. This dissertation addresses this gap by examining how consumption becomes socially evaluated and judged across different contexts, with the goal of advancing both theoretical understanding and practical insights into socially sensitive consumption.

Ornithine Metabolism In Retinal Pigment Epithelium And Retina And Implications In Gyrate Atrophy, Artjola Puja

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ornithine aminotransferase (OAT) is a mitochondrial enzyme that regulates ornithine metabolism by converting ornithine to pyrroline-5-carboxylate, a precursor for proline and glutamate synthesis. Deficiency of OAT causes systemic ornithine accumulation and leads to gyrate atrophy (GA) of the choroid and retina, a hereditary disorder characterized by progressive chorioretinal degeneration and irreversible vision loss. Chorioretinal atrophy typically starts at the mid-peripheral retina and progresses toward the macula. Although elevated ornithine is considered toxic to the eye, how ornithine is metabolized in ocular tissues and why OAT deficiency causes selective, region-specific vulnerability remain unclear. We combined ex vivo and in vivo stable …

Three Essays In Cpi Bias And Health Economics, Auderta Amoako-Nuamah

Graduate Theses, Dissertations, and Problem Reports (ETD)

The first essay estimates bias in the Consumer Price Index (CPI) for elderly individuals in the United States using Engel curve methodology and household-level data from the Panel Study of Income Dynamics (1999–2023). The analysis focuses on how well the CPI reflects changes in the cost of living for older Americans, with particular attention to differences by gender and marital status. Results show that from 1999–2011, the CPI overstated the increase in the cost of living for both elderly and non-elderly households.
