Institutional And Structural Evolution Of The U.S. Financial System 1945-2023: The Long-Wave Financial Cycle And The Role Of Thwarting Mechanisms, Shaun K. Brog

Electronic Theses and Dissertations

This thesis develops a theoretical framework that attempts to explain the dynamic interactions that lead to episodes of severe financial instability. Adapting Minsky’s Financial Instability Hypothesis to the specific characteristics of financial intermediaries and building on Ferri and Minsky’s ideas regarding the role of thwarting institutions, I propose that financial fragility is the result of a long-wave cycle in financial relations characterized by significant institutional and structural evolution within the U.S. financial system. This evolution results in a preponderance of financial activity undertaken outside the regulatory umbrella while margins-of-safety are eroded, newly innovated financial assets proliferate, and financial intermediaries become …

Changing The Narrative: Student Empowerment In Unequal School Contexts, Stephanie A. Nisle-Mikos

Electronic Theses and Dissertations

Educational experiences affect a wide variety of life outcomes for individuals. The type of education an individual receives influences their occupation, the neighborhood in which they live, and even their risk of mortality (National Research Council, 2013; Sasson, 2016). In particular, the life trajectories of students who attend high-poverty schools are not the same as youth who attend schools with greater resources (National Center for Education Statistics [NCES], 2013; Taylor, 2005). In this dissertation, I provide a brief background on current rates of disproportionality in education and examine how specific theoretical constructs and educational policies may be used to explain …

How Well Do Nature-Based Solutions To Climate Change Address Gender Equity?, Stephanie Efua Yamoah

Electronic Theses and Dissertations

As the climate crisis continues to deepen, there have been calls for adaptation and mitigation approaches that rely on nature-based solutions. These solutions are approaches that offer the potential to reduce and remove greenhouse gas emissions. Examples include forest restoration, coastal wetland conservation, and no-till agriculture, among other practices. In this thesis, I employ an intersectional feminist political ecology perspective to critically examine the integration of gender equity within such nature-based solutions. I make two interrelated arguments using a qualitative methodology and an intensive case study of three projects in Ghana. First, I argue that women’s participation in nature-based solutions …

Characterization Of Oxidized Tau Protein Aggregation And Inhibition Of Tau Aggregation Via Map2, Brad Krzesinski

Electronic Theses and Dissertations

Neurofibrillary tangles (NFT) composed of the microtubule stabilizing protein Tau are a pathological hallmark of Alzheimer's disease (AD) and many other dementia related diseases specified as Tauopathies. Due to alternative mRNA splicing, intrinsically disordered Tau exists as six separate isoforms in the adult human brain where they are categorized by the lack or inclusion of the second repeat in the microtubule binding domain (3R or 4R respectively). Isoforms are subcategorized by the inclusion or lack thereof, one or two N-terminal inserts. Many studies show that Tau aggregates into amyloid fibrils and these fibrils can break into small oligomeric units known …

Understanding The Nuances Of Transit Accessibility: Temporal And Spatial Resolution, And Neoliberalism, Joe Chestnut

Electronic Theses and Dissertations

This dissertation explores accessibility via public transit through several lenses. In doing so, some of the lesser known nuances of accessibility are better understood. These nuances are explored in several ways. First, various demographic variables and their relationship to accessibility to jobs via public transit are modeled at a fine spatial resolution in an exploratory analysis across several cities in the United States. Next, temporal and spatial resolution and their impacts on accessibility to jobs via public transit are analyzed and quantified in several cities across the United States. Finally, the relationship between neoliberalism and public transit accessibility is explored …

Morphological Remodeling Of The Endoplasmic Reticulum During Mitosis And Its Influence On The Integrity Of The Spindle Apparatus, Katie R. Rollins

Electronic Theses and Dissertations

The Endoplasmic Reticulum (ER) is the largest organelle in the cell by surface area and forms contacts with other organelles throughout the cell. In recent work, the ER has been implicated in numerous processes within the cell beyond its canonical roles of protein synthesis and calcium storage. The ER also undergoes a remarkable transition in morphology during cell division, with mitotic divisions requiring a massive remodeling of various membranous organelles such as the nuclear envelope and Golgi. However, whether changes in ER behaviors modulate mitotic events is less clear. The rapid cleavage divisions in the early Drosophila embryo are a …

The Effects Of Wildfire Burn Severity On Bee And Wasp Communities Two Decades Post-Fire, Alaina K. Smith

Electronic Theses and Dissertations

While fire is a natural disturbance in many global ecosystems, anthropogenic changes are affecting fire frequency, severity, and seasonality. Disturbances like wildfire affect bee and wasp communities, but recent meta-analyses are conflicted about whether fire harms or benefits insect pollinators. We investigated the lasting effects of wildfire burn severity on wild bee communities and floral resource availability across different burn severities in two-mixed severity fires that burned >20 years ago. We found that high severity fire has positive effects on bee diversity that are associated with severity-mediated changes to the floral community. We also studied the effects of wildfire burn …

Statistical Modeling Of Knee Morphology And Material Properties Considering Diverse Populations, Gabrielle Jeannine Kindy

Electronic Theses and Dissertations

Total Knee Arthroplasty (TKA) is a widely performed surgical procedure aimed at alleviating pain and restoring function in patients with severe knee osteoarthritis. Despite its general success, disparities in postoperative outcomes have been observed across different racial and ethnic groups, with minority populations often experiencing less favorable results. One potential avenue for improving the generalizability of orthopaedic implants is using Statistical Shape and Intensity Models (SSIMs), which can be used to incorporate patient variability directly into the orthopaedic medical device development workflow through population-based finite element analysis.

This work aimed to construct an SSIM from a diverse subject set, incorporating …

Patient-Specific Musculoskeletal Modeling Of Total Shoulder Arthroplasty, Brendan M. Curran

Electronic Theses and Dissertations

Total shoulder arthroplasty (TSA) is often considered a surgery of last resort for patients with debilitating pathologies of the glenohumeral joint such as osteoarthritis, humeral head fracture, and advancing rotator cuff tears. TSA replaces the articulation between the humeral head and the glenoid fossa, with the goals of relieving pain and restoring function. Two types of total shoulder implants are available: Anatomic Total Shoulder Arthroplasty (aTSA) and Reverse Total Shoulder Arthroplasty (rTSA). TSA survivorship is lower than that of the survivorship seen in total knee and hip replacements [1]. Shoulder muscle moment arms and lines of action have been measured …

Understanding The Misunderstandings: Using Deliberative Democracy And Communication Ethics To Overcome Societal Polarization In Post-Truth America, Jessica Neu

Electronic Theses and Dissertations

This work contributes to communication scholarship by advancing the discussion of deliberative democracy to include communication ethics and popular culture artifacts to use as case studies in an exploration of how to engage in a type of dialogic civility that acknowledges identity politics without allowing it to be a barrier to progress in a post-truth society. As such, this work provides a sense of how to engage in conversation that recognizes and hears the Other in a way that makes all stakeholders uncomfortable. From this discomfort comes growth, as individuals do not necessarily need to completely alter their ideologies, morals, …

A Gift Not Given: An Examination Of Disproportionality For Black Students And Gifted Education Through The Lens Of Representation And Improvement, Casey Weiss

Electronic Theses and Dissertations

Giftedness is a particular trait giving designation to a specific group of people in a school population. While identification methods vary from state to state, the status of being gifted is granted to some students, creating a dichotomy of those who receive gifted services and subsequent privileges and those who remain left out. Historically, Black students and other marginalized populations have had less participation in gifted programs. The literature highlights several factors connected to inequity in giftedness including lack of a cohesive definition of the term (or even if the concept of giftedness is real or socially constructed), nomination and …

Depositional Facies Analysis Of The Cotton Valley Group Sandstones Of The Blackburn Field, Northern Louisiana Using Well Logs And Cores; Implications For Carbon Sequestration, Frederick Owusu

Electronic Theses and Dissertations

The Cotton Valley Group (CVG) consists of tight sandstones with heterogeneous reservoir properties due to variations in depositional environments and diagenesis, spanning across eastern Texas through the Florida panhandle. It has served as a hydrocarbon target since the 1940s, and with recent technological advances, there is renewed exploration of the tight reservoirs within the group. Across northern Louisiana, the CVG has moderate to good reservoir properties, whereas those south extending westward across the Sabine uplift into east Texas decrease in porosity and permeability. With reservoir depletion coupled with its relatively simple mineralogy, these sandstone units may serve as good, localized …

Exploring The Mandelbrot Set, James Shirley

Electronic Theses and Dissertations

The Mandelbrot set is a mathematical mystery. Finding its home somewhere be-
tween holomorphic dynamics and complex analysis, the Mandelbrot set showcases
its usefulness in fields across the many realms of math—ranging from physics to nu-
merical methods and even biology. While typically defined in terms of its bounded
sequences, this thesis intends to illuminate the Mandelbrot set as a type of param-
eterization of connectivity itself, specifically that of complex-valued rational maps
of the form z → z² + c. This fully illustrated guide to the Mandelbrot set merges
the worlds of intuition and theory with a series of …

Aristotle's Division Of The Sciences And The Impossibility Of A Science Of Everything, Christopher Lutz

Electronic Theses and Dissertations

Aristotle’s division between practical, productive, and theoretical sciences is widely acknowledged, and it is uncontroversial to say that it organizes his texts. However, contemporary scholarship often treats the division of the sciences as a mere organizational structure without investigating its underlying principles. My dissertation seeks to correct this oversight by investigating the logical principles of Aristotle’s division of the sciences in the Posterior Analytics’ account of scientific knowledge (ἐπιστήμη). My central argument is that Aristotle sees the sciences as inherently divided, so that a demonstrative science of everything is impossible. By understanding why science is divided, we are better …

Evaluation Of Changes In Evaporative Losses From Lake Powell Reservoir Contributions In The Colorado River Basin, Maria Mlinarcik

Electronic Theses and Dissertations

The Colorado River Basin (CRB) is one of the most critical water sources for the western United States (U.S.) and Mexico. For over a century, numerous policies and regulations have been implemented in attempts to manage the Colorado River Basin to address the concern of overuse, collectively referred to as the “Law of the River.” The USGS hydrologist E.C. LaRue warned that the optimistic estimates used in negotiating the Colorado River Compact did not align with the actual water availability in the river. His analysis in 1925 revealed a potential deficit if all allocated water was utilized, exacerbated by overallocation …

Teachers' Experiences With Teaching For Social Justice In Tracked Middle School Mathematics Classes., Stephanie Jean White

Electronic Theses and Dissertations

Tracking is a longstanding structure in K-12 mathematics that decades of research has shown to be inequitable. Despites calls to detrack mathematics classes, most U.S. schools retain tracking. Mathematics educators have attempted to implement teaching pedagogies such as Teaching for Social Justice (TSJ) that promote equity in all mathematics classrooms, including tracked classes. This research used the Learning to Teach for Social Justice Belief (LTSJ-B) Scale with middle school mathematics teachers who have taught in tracked classes to measure their levels of commitment to TSJ. This research also employed case study methodology with three teachers and cross-case analysis using TSJ …
