Genomic Differences And Parentage In West Virginia's Reintroduced Elk (Cervus Canadensis), Adam A.V. Cook

Graduate Theses, Dissertations, and Problem Reports (ETD)

Elk (Cervus canadensis) reintroductions have been common in the 20th and 21st centuries, yet 40% have failed to establish self-sustaining elk populations due to a lack of post-reintroduction demographic monitoring. Elk were reintroduced to West Virginia in 2016 following more than a century of absence after the species was extirpated in 1875. Elk were translocated to West Virginia from Land Between the Lakes National Recreation Area (LBL) in eastern Kentucky and from Arizona. The two groups of elk differ in their subspecies, physiology, reintroduction history, connectivity, and habitat. Reintroductions create genetic risks such as the founder effect and …

When The Empires Strike Again: The Effects Of An Imperial Past On The Post-Cold War International Order, Begum Wolfe

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although on the surface empires appear to be ancient and irrelevant political constructs from a distant past, I argue in this dissertation that even after the empire officially dissolves, the core of the bygone empire continues its political existence in the mindsets of the empire-bearing people. This is mainly explained through certain imperial memories, glories and traumas, that have permeated into these states’ identities. In these so-called post-imperial states, then, such a unique experience of having functioned as an empire translates into foreign policy behavior that is patterned, predictable, but also puzzling especially regarding certain issues with an imperial baggage. …

Influence Of Deck Area And Average Daily Traffic On The Deterioration Of Bridge Superstructures., Faysal Ahamed

Graduate Theses, Dissertations, and Problem Reports (ETD)

State Departments of Transportation (DOTs) are responsible for maintaining approximately 623,000 bridges across the United States. Effective bridge management requires a comprehensive understanding of the factors influencing structural deterioration. Numerous studies have explored the effects of average daily traffic (ADT) and deck area (DA) on bridge deck deterioration. Given the interdependence between bridge decks and superstructures, it is plausible that ADT and DA significantly influence superstructure condition ratings and deterioration trends. However, their impact on superstructures remains insufficiently studied. In addition, existing studies primarily focus on overall bridge deterioration without adequately differentiating between superstructure designs and materials and maintenance authorities. …

Refinement Of A Thermodynamic Model To Explain The Weathering Patterns Of Ignitable Liquids On Household Substrates At Elevated Temperatures, Chaney Ashlyn Ganninger

Graduate Theses, Dissertations, and Problem Reports (ETD)

ABSTRACT

Refinement of a thermodynamic model to explain the weathering patterns of ignitable liquids on household substrates at elevated temperatures

Chaney A. Ganninger

In 2021, arson caused more than 4,361 deaths in the United States. To aid in the differentiation between arson and accidental or natural causes, investigators often analyze fire debris for the presence of ignitable liquid residues using headspace concentration followed by gas chromatography-mass spectrometry (GC-MS). Classification of ignitable liquids can be confounded by weathering, which is the uneven evaporation of compounds in ignitable liquid residues. The Jackson group, among others, has developed a thermodynamic model to help …

Creative Energies: Unearthing The Role Of Romantic Ecocriticism, Nicole Marie Chambers-Stahl

Graduate Theses, Dissertations, and Problem Reports (ETD)

The literary field of ecocriticism has transcended the boundaries of Academia: excited to connect to their physical environments, many of these scholars are focusing on genres like place-based writing, rhetoric of energy policy, and representations of the Earth in film and media. Interdisciplinary by nature, ecocriticism has demonstrated clear potential in its ability to intersect with concentrations like the history of science, animal studies, and environmental justice.

However, as the language around global crises is heating up —“Today it is scientists, not prophets,” writes Tobias Menely in “‘The Present Obfuscation,’” “who speak the language of apocalypse” (478)—ecocritical scholarship is at …
