Analysis is derived from Uses and Gratifications theory and scholarship on star power. The research shows …

The Potential Of Diabase Sills In Eastern Pennsylvania To Store Co2 And H2, Rhiannon R. Schmitt

Graduate Theses, Dissertations, and Problem Reports (ETD)

With anthropogenic CO₂ concentrations rising, geologic carbon sequestration and H₂ storage are essential processes in mitigating climate change. Typical geologic carbon sequestration involves the capture of anthropogenic CO₂ and injection into depleted oil/gas reservoirs or saline formations with an impermeable cap rock to prevent the buoyant migration of CO₂. The risk of eventual CO₂ migration through these low permeability cap rocks adds expensive monitoring costs to this traditional sequestration strategy. Another method for CO₂ sequestration utilizes the reaction of CO₂ with mafic and ultramafic rocks. CarbFix, a sequestration project in Iceland, has …

Legacy impacts from these historic disturbances along with contemporary stressors in the form of continued industry, changing climates, altered land use, habitat fragmentation, and introduced species can present great threats to the region’s aquatic ecosystems. Brook Trout Salvelinus fontinalis are a species that has recreational and economic importance to the communities of central Appalachia but declines in size and abundance have been observed. Given the disturbances that threaten Brook Trout populations, understanding how their populations will respond to …

Narrative Transportation In Documentary Film: How Immersion Into The Documentary Film Hillbilly Affects Viewers' Attitudes, Alayna G. Fuller

Graduate Theses, Dissertations, and Problem Reports (ETD)

For decades, film has relied on stereotypical misconceptions to depict Appalachian people on screen. Research has demonstrated that visual narratives and the experience of narrative transportation has the power to change individuals’ perceptions about information conveyed implicitly or explicitly within a story. Presently, no empirical research has examined how viewer attitudes form based on their level of immersion into an Appalachian documentary film. To fill this gap, this study offers a quantitative approach to examine if the documentary Hillbilly narratively transports the viewer into the world of Appalachia and shifts audience perceptions of the stereotypical Appalachian persona or “hillbilly.” The …

Exploring How Children Use Their Everyday Thinking To Construct Scientific Explanations Of The Natural World, Ashley Nicole Kooken

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this qualitative grounded theory study was to describe and explain children’s thinking present in multiple related contexts surrounding a single Earth Space disciplinary core idea in order to provide insight on whether and how children’s everyday thinking forms the basis for learning in science classrooms. As most previous work on children’s thinking focuses more on what ideas and thinking are present within specific science learning contexts, there is a knowledge gap as to how children’s everyday ideas across multiple contexts provide the basis from which they construct a deeper conceptual understanding about scientific phenomenon in the world …

Tax Avoidance, Corporate Governance, And Corporate Policies, Yang Yang

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation includes three essays examining the interactions between tax avoidance, corporate governance, and corporate policies. The first essay exploits corporate governance shocks induced by cross-listing in the U.S., and find that firms tend to engage in less tax avoidance after cross-listing. This effect is more pronounced for firms that experience significant improvements in corporate governance, and for firms from countries with weaker shareholder protection and disclosure requirements. Taken together, the results indicate that cross-listing in the U.S. helps align the interests of managers and shareholders and reduces managerial diversion.

The second essay examines the importance of tax avoidance to …

Mtdna Heteroplasmy In Hair Shafts Versus Buccal Swabs For Forensic Applications, Sara R. Bodnar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mitochondrial DNA (mtDNA) analysis has several forensic applications such as criminal investigations, identification of human remains, and missing person investigations. It is also the only type of DNA that is available from certain sample types such as hair shafts. The presence of mtDNA heteroplasmy within and between tissue types can lead to mtDNA sequence differences when comparing samples originating from the same individual. Studies on mtDNA heteroplasmy are increasingly being carried out for their implications in forensic interpretation of mtDNA sequences. Specifically, mtDNA in buccal swabs compared to hair samples from one individual may show differences in sequence due to …

Structural And Petrologic Insights Into The Emplacement Of Effusive Silicic Lavas: Inyo Domes, California, Shelby L. Isom

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Long Valley volcanic region, eastern California, USA is most famous for the caldera-forming eruption which produced the Bishop Tuff ~760,000 years ago. Over the last 3,000 years volcanism has been focused in the western margin of the region through punctuated eruptions of silicic lavas and domes. Three simultaneous effusive silicic eruptions, ~600 years ago, generated three lava domes: Obsidian Dome; Glass Creek Dome; and Deadman Dome which erupted onto vastly different topographies. These domes are exceptionally unique as they erupted variable amounts of two textural and chemical endmember lavas (crystal-rich and crystal-poor) that intimately mixed. The overarching goal of …

Evaluating Muskellunge (Esox Masquinongy) Catch-And-Release Mortality At Elevated Summer Water Temperature, Ian Taylor Booth

Graduate Theses, Dissertations, and Problem Reports (ETD)

Angling for Muskellunge (Esox masquinongy) has become widespread and increasingly popular throughout the fish’s range. Current management strategies for Muskellunge include high minimum harvest lengths (>1016mm), closed seasons, and catch-and-release regulations. Due to these strategies and angler sentiments, up to 97% of Muskellunge caught today are released by anglers assuming they will live and be caught again in the future. Previous research on catchand-release mortality in Muskellunge has suggested relatively low mortality rates (0%-5%). However, these studies were all conducted within the fish’s thermal optimum and generally at water temperatures25°C during the summer months, representing a need to evaluate …

Genetic Assessment Of Lake Sturgeon Stocking Practices In Two Lake Superior Tributaries, Mary E. Akers

Graduate Theses, Dissertations, and Problem Reports (ETD)

Lake sturgeon were extirpated throughout much of their historic range in the early 1900s due to overharvest, habitat degradation, and reduced water quality. Interagency management plans have worked to identify historic locations and remnant populations suitable for stocking and habitat remediation to rebuild self-sustaining populations of lake sturgeon within their historic range. The St. Louis River population was extirpated in the early 1900s until lake sturgeon were stocked from 1983-2000 from two different source populations (Wolf River, Sturgeon River). Natural reproduction was confirmed in 2011 and F1 generation larvae were collected in 2017 (n = 41) and 2019 (n = …

The Role Of Firm-Level Pdo In Asymmetrically Dependent Marketing Channel Relationships, Yuerong Liu

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation introduces power distance orientation (PDO) at firm level to extend the traditional view of power/dependence asymmetry. The traditional view suggests that the powerful firm will exploit its power for its own interest, and the dependent firm will engage in a preemptive strike (e.g., engage in self-interested, guileful behaviors before the powerful partner exploits them) due to its fear of being exploited. As a result, power/dependence asymmetry leads to deleterious relationship outcomes. Yet, power dependence theory does not consider the role of power dependence orientation, which is a firm’s acceptance of unequally distributed power. This dissertation consists of three …

Feed Conditioning Effects On Enzymes, Amino Acids, And Subsequent Broiler Performance, Elizabeth Ann Lynch

Graduate Theses, Dissertations, and Problem Reports (ETD)

There are many things that can be done to improve broiler performance including, but not limited to, pelleting, proper Lys inclusion, and exogenous enzyme supplementation. Pelleting has the ability to improve feed form, reduce wastage, improve bird performance metrics, and decrease pathogens within the feed. Pathogen reduction can be further reduced by hygienic pelleting practices which include an increase in temperature or retention time within a conditioner or hygieniser. However, hygienic pelleting can degrade valuable AA and enzymes (more specifically for the current thesis research Lys and phytase) and make them unavailable to the animal. Supplementing Lys to account for …

Bayesian Methods For Multi-Messenger Analysis Of Supermassive Black Hole Binaries: Pulsars And Quasars And Gravitational Waves, Oh My!, Caitlin A. Witt

Graduate Theses, Dissertations, and Problem Reports (ETD)

Supermassive black hole binaries (SMBHBs) can lurk, often unseen, in the centers of post-merger galaxies, and pulsar timing arrays (PTAs) are rapidly approaching the sensitivities required to detect nanohertz gravitational waves (GWs) from these giant pairs. Independently, numerous electromagnetic surveys are seeking evidence of these dynamic duos’ effects on their host galaxies by searching for periodicities in time-domain observations. Combining these two methods to use multi-messenger techniques allows us to learn more about these binaries than using one messenger alone. In this thesis, we have created Bayesian methods to search for SMBHBs using electromagnetic observations of quasars and through GW …
