Some Results In Thermodynamic Formalism, C. Evans Hedges

Electronic Theses and Dissertations

This dissertation investigates several key questions at the intersection of dynamical systems, computability theory, and thermodynamic formalism. In the symbolic setting, we establish novel results regarding the statistical properties of equilibrium states, deriving bounds on probabilities of configurations and relating these bounds to the Gibbs property through the homoclinic relation. Additionally, we examine the computability of thermodynamic quantities such as pressure, ground state energy, and residual entropy. We show that topological pressure is computable from above for general subshifts and computable for strongly irreducible shifts, with similar results extending to ground state energy and residual entropy.

Extending beyond subshifts, we …

The Embodiment And Experiences Of Gender Euphoria Among Transgender And Nonbinary Communities: A Mixed Methods Inquiry, Brendon T. Holloway

Electronic Theses and Dissertations

Gender euphoria is a critical aspect of embodiment for transgender and nonbinary (TNB) people that has long been overshadowed in academic research by deficit narratives and gender dysphoria. While gender dysphoria is the distress an individual may experience related to their gender, gender euphoria encapsulates the positive emotions a TNB person may experience because of positive gendered experiences. Despite community documentations of gender euphoria since the 1970s, academic research on gender euphoria has only recently begun to emerge. This three-paper dissertation advances this body of scholarship by exploring how gender euphoria is conceptualized, experienced, and embodied in TNB communities. Utilizing …

The Narratological Maus, Isla Lader

Electronic Theses and Dissertations

The Complete Maus, a memoir graphic novel surrounding the events of character Art Spiegelman as he collects, records, and illustrates his father’s life pre-the Holocaust in Europe, his time in Auschwitz, and then life in the United States has been one of the focal Holocaust survivor testimonies and has redefined the genre it exists in as both a graphic novel, but also as a form of testimony. Like many popularized works dealing with the Holocaust, though, cultural preconceptions of Jewish people, genocide, and audiences’ desire to find morals within the work have made it so often audiences come to …

Much of southwestern Pennsylvania has been central to a rapid increase in development for unconventional natural gas extraction in the past two decades. The continued monitoring of streams over their lifetime as extraction sites is pivotal to understanding the effects of fracking on local waterways and their ability to provide for wildlife and human use. Here, using multiple indices of biotic integrity (IBI), I perform analyses of fish and macroinvertebrate communities as well as water chemistry on two streams, Bates Fork (with shale wells) and Fonner Run (without), as part of a follow-up to work performed there from 2010-2012. Fish …

A Raced Theology Of The Human Person: An Expanded Theological Anthropology, Cary W. Dabney

Electronic Theses and Dissertations

This dissertation focuses on race as a critical, yet largely unaddressed, topic in Catholic theological anthropology. In Catholic colleges and universities that are recognized as members of the Cardinal Newman Society, theological concerns about race are deemed irrelevant for theological education in the faith and are altogether absent from the theology of the human person. As a result, this collection of institutions treats race as a specialty within pastoral theology, one that is significant to groups, but not a part of the fundamental theology of the human person. This ‘un-raced’ theological anthropology results in the institution’s inability to respond effectively …

Communicative Harmonics: A Synchronization Of Minds, Manners, And Emotions As A Phenomenological Approach To Resonant Leadership, Victor J. Grigsby

Electronic Theses and Dissertations

At the heart of human relationality and resonant leadership is an interpersonal vibration that creates group coherence. The fusion of minds, manners, and emotions is a synchronization of individual vibrations and frequencies that unite the human spirit. Communicative harmonics presupposes the necessity for dialogue as the interconnection of contrasting perspectives. The auditory framework of speaking and listening parallels that of leading and following and is used to explore dialogic leadership as a major element in leadership communication. This dissertation is modeled after the work of Kenneth Burke’s dramatistic pentad and incorporates a musical pentad of tone, rest, frequency, rhythm, and …

Entropy And Incarnation In The Duchamp Room: An Inquiry Into Aesthetic Time, Jesse Goodman

Electronic Theses and Dissertations

This thesis investigates the posthumous installation of Marcel Duchamp, Étant donnés, as a test case for how particularly historically situated artworks may or may not change over time. It begins with an overview of Duchamp’s biography, and his own theories of art’s relationship to temporality (which influenced the piece’s construction). It then moves through contrasting accounts of aesthetic time from Adorno and Robert Smithson. Section two works with Walter Benjamin’s writing on photography and aura to produce an account of estrangement between the piece and the viewing subject induced by the historical development of the artwork’s “translation” and “replication”—through …

The Contribution Of Catholic Compromise Principles In Global Health, Scott N. Helstad

Electronic Theses and Dissertations

The Roman Catholic tradition has developed comprehensive ethical principles to address complex practical scenarios that encounter foundational value compromises. These are referred to as compromise principles and they have both a narrow and a broad focus. Narrowly, these compromise principles are critical for Catholic healthcare organizations in the United States with regard to the guidelines of the US Bishops in their Ethical and Religious Directives for Catholic Health Care Services.

On The Deconstruction Of Nothingness In Digital Communication, Matthew S. Lindia

Electronic Theses and Dissertations

This project argues that digital technologies call for a new problematic of communication, centered around the conditions of (im)possibility for creating perfect digital profiles of users as generated from user data. Beginning with Edmund Husserl’s analysis of essentially occasional expressions, this dissertation posits that user data occurs on three levels: (1) the level of expression, where a user wants-to-say something through their inputs, (2) the level of facticity, where biometric data are involuntarily produced by the user, and (3) the level of nothingness, where the user’s inaction, such as not-answering, is taken as data. Moving beyond what Husserl’s framework can …

Demography Of Alligator Snapping Turtles (Macrochelys Temminckii) Along A Fishing Pressure Gradient, Luke T. Micek

Electronic Theses and Dissertations

Passive fishing gear is a threat to the alligator snapping turtle (Macrochelys temminckii). The spatio-temporal persistence of this threat and its impacts on M. temminckii populations has not been quantified. I quantified the density of passive fishing gear and the demographic parameters of M. temminckii along a fishing pressure gradient in East Texas streams. Most gear was abandoned and illegally deployed, with densities varying seasonally. Detectability of passive fishing gear declined with increasing gear age, water depth, and volume, but increased with increasing precipitation. Macrochelys temminckii catch per unit effort, abundance, and survival was lower at sites with …

Exploratory Learning Before Instruction: Comparing Individual Exploration, Collaborative Exploration, And Preparation For Future Collaboration., Raina Isaacs

Electronic Theses and Dissertations

Instructors often prioritize traditional instruction in the classroom, despite evidence supporting the use of active learning methods. Exploratory learning, presenting novel problems to students before presenting information about the procedure and underlying concepts, can improve students’ conceptual understanding of instructional material. In exploratory learning, collaborative learning is often an important component of the instructional design. However, few researchers have directly compared collaborative and individual exploration to determine if there are benefits of adding collaboration to exploration. By disentangling exploratory and collaborative learning, we can learn how and why collaborative exploration fails or succeeds. One idea is that adding individual preparation …

Advancing Research On Retinitis Pigmentosa: An Investigation Of Natural History, Visual System Plasticity, And Mutation-Independent Treatment., Cecilia A. Attaway

Electronic Theses and Dissertations

Retinitis Pigmentosa (RP) is an inherited retinal disease characterized by rod and then cone photoreceptor degeneration. ~25% of cases are caused by a genetic mutation that results in autosomal dominant RP (adRP). There has been a lack of exploration of the progression of degeneration in adRP models. In Chapter Two, I examined visual acuity (VA) changes, retinal structure, and function from early to late-stage disease in a murine P23H Rho ‘knock-in’ mouse model (Rho^P23H/+), the most common form of adRP in North America. To establish a natural history, I evaluated behavioral VA, using the visual water task, …

Exploring The Impact Of Social Interactions And Representation On The Development Of Engineering Students' Sense Of Belonging In A Summer Program., Liliana Martinez

Electronic Theses and Dissertations

Research has shown that engineering students from underrepresented minority (URM) populations experience significant retention gaps compared to their majority peers (Dickerson et al., 2014). One factor that can significantly promote academic success, retention, persistence, and psychological adjustment is a sense of belonging (Hausmann et al., 2007; Hoffman et al., 2002). There is evidence showing that Summer Bridge Programs (SBPs) can foster students’ sense of belonging (Strayhorn, 2019); however, little is known about the mechanisms through which an SBP impacts URM engineering students’ sense of belonging. This study addresses this knowledge gap by investigating the impact of the Brown Forman …

The Dynamic Role Of Hyaluronan In Acute Cardiac Wound Healing., Danielle T. Little

Electronic Theses and Dissertations

During acute myocardial infarction (MI), the composition of the extracellular matrix (ECM) undergoes significant changes. While collagen accumulation is one of the most well-documented ECM alterations, hyaluronan (HA) is equally abundant. However, the cellular sources, enzymatic regulation, and functional significance of HA accumulation remain largely unexplored. Here, we hypothesized that activated cardiac fibroblasts produce HA via hyaluronan synthase 2 (HAS2), facilitating scar formation and stability. Our findings demonstrate that HA accumulates post-MI and persists for at least four weeks. Through HA sizing techniques, we determined the molecular weight of this persistent HA. Additionally, RNA sequencing analysis of failing human hearts …
