From Curiosity To Controversy: American Perception Of Japanese Immigrants, 1853-1924, Chloe Elizabeth Curbelo

Theses and Dissertations

In the mid-nineteenth century, as the United States reached the Pacific through westward expansion, Asia emerged as a new stage for commerce and power. Japan, long isolated under the Tokugawa shogunate, became an object of American fascination when forced into relations. While early depictions cast Japan as an exotic yet uncivilized nation in need of Western guidance, Japan’s rapid modernization and the growing number of Japanese immigrants on the West Coast transformed curiosity into anxiety. My paper traces this evolution of perception from 1850 to 1924, arguing that shifting views of Japan and its people reflected America’s ethnocentric notions of …

Hillslope Degradation: Coarse Sands May Move Faster But Fines Dominate Flux, Robert Chance

Theses and Dissertations

Hillslopes are one of the most pervasive landforms on Earth yet the details of the processes that drive their evolution are not completely understood. Excluding boulders, the majority of mass and volume in soil-mantled hillslopes is composed of sand-sized and finer grains. Understanding the transport rates and governing transport mechanisms of these grains is therefore key to advancing our knowledge of hillslope evolution.This research investigates sand-sized sediment transport through field experiments at 20 sites tracking surface sediment motion and 11 sites measuring depth-dependent transport. These empirical results are compared against outputs from a novel grain-based hillslope diffusion simulation (GBHDS), which …

From Ink To Code, From Binary To Boundless Reality—Until All Returns To Emptiness, Weitong Sun

Theses and Dissertations

This thesis explores the entangled relationship between language, memory, and technology through the lens of immigrant experience. Moving from programming to visual storytelling, I investigate how dyslexia, bilingualism, and cultural displacement have shaped my ways of reading, writing, and coding.

Beginning with personal reflections on switching from computer science to art, I trace how code offered a form of clarity and expression where written language had once failed me. Yet as I ventured into real-time simulation and XR storytelling, I encountered new forms of mistranslation—where narratives dissolved, mutated, or resisted coherence altogether.

Through a series of experiments in code-driven art, …

Assessment Of Drivers Of Light Attenuation In Virginia Reservoirs, Jackson Barnett

Theses and Dissertations

Water clarity in aquatic ecosystems is crucial for submerged vegetation and algal dynamics. We investigated the factors influencing light attenuation (kd) by measuring total suspended solids (TSS), chlorophyll-a (CHLa), and chromophoric dissolved organic matter (CDOM) across thirteen stations located in seven reservoirs. Average kd was 1.69 m^-1 (range: 0.37-3.99 m^-1), with photic depths averaging 3.27 m (range: 1.15-12.43 m). TSS was the primary predictor of light attenuation (R² = 0.57, P = 0.003, SE = 0.053). Average TSS values for each site were multiplied by the slope of the kd-TSS relationship to find the proportion of kd …

Existing In The Context: A Conjunctural Analysis Of Kamala Harris Memes, Amaya Mcneal

Theses and Dissertations

Political memes have become a common way for people to express their political views online, helping politics reach young adults who weren’t previously interested. Consequently, politicians have begun sharing and creating memes themselves. The memeification of American politics has diminished debate about ideas, ideals, issues, and people’s vital interests, debasing voters by treating them not as citizens but as passive “consumers” and “spectators” of mediated politics. This paper helps make sense of this crisis, focusing on the example of former Vice President Kamala Harris. Vice President Kamala Harris' memeified presidential campaign during the 2024 U.S. election targeted voters through a …

Substrate Preference And Foraging Behavior Of Two Declining Warblers In Appalachian Shrublands, Samantha Fishman

Theses and Dissertations

Abstract Shrubland and early successional habitats (ESH) support a diversity of wildlife, including many declining songbirds. However, nonnative shrubs increasingly dominate these habitats, potentially altering habitat quality by influencing prey availability. Habitat quality can be assessed by observing foraging behaviors of songbirds and identifying preferred and avoided substrates as well as testing the predictions of optimal foraging theory; specifically that birds will maximize their energy gain relative to the costs. We examined foraging behaviors of Golden-winged Warblers (Vermivora chrysoptera; GWWA) and Chestnut-sided Warblers (Setophaga pensylvanica; CSWA) in ESH on private lands in Virginia with varying amounts …

Climate Change-Induced Shifts In Mediterranean Fungal Fruiting Phenology And Productivity, Rachel Demay

Theses and Dissertations

We used a 29-year dataset of mushroom fruiting from the Pinar Grande forest in northern Spain to investigate the effects of climate change on the phenology, productivity, and diversity of mycorrhizal and saprotrophic mushrooms. We investigated the long-term trends in fruiting season length, yield (by count, total weight, and average weight), and genus richness. Additionally, we identified associations between monthly temperature and monthly precipitation with these fungal responses across functional groups: mycorrhizal, saprotrophic, litter-decaying saprotrophic, and wood-decaying saprotrophic mushrooms, and the economically-important edible genera Boletus and Lactarius. We found that autumnal season length in the Pinar Grande has shortened over …

Scopolamine-Induced Modulation Of Serotonin And Dopamine Transporters Activity: Behavioral And Molecular Insights Into Rapid Antidepressant Action, Deepak Karunakaran

Theses and Dissertations

Major depressive disorder (MDD) affects over 350 million individuals worldwide and is characterized by profound dysregulation of serotonin (5-HT) and dopamine (DA) systems that govern mood, reward processing, and motivation. The serotonin transporter (SERT) and dopamine transporter (DAT), both dynamically regulated through phosphorylation, serve as critical determinants of synaptic monoamine signaling. Despite decades of therapeutic development, current antidepressants require 4-6 weeks to achieve efficacy, and approximately one-third to half of patients develop treatment-resistant depression. The emergence of rapid-acting antidepressants like ketamine represents a paradigmatic shift, demonstrating symptom relief within hours; however, ketamine's therapeutic potential remains constrained by abuse liability, dissociative …

Mental Silence For Emotional Intelligence Development, Mina N. Nandwani

Theses and Dissertations

While emotional intelligence is considered key for effective leadership, and perhaps the most vital competency for current and emerging leaders to cultivate, there appears to be uncertainty on how to develop it. This study examined how the practice of Sahaja Yoga Meditation (SYM) influences the development of emotional intelligence and contributes to the advancement of global leadership capacities, addressing a gap in the current literature. The conceptual frameworks of SYM, Daniel Goleman’s Emotional Intelligence Model, and the literature on global leadership, particularly Jeffrey Sachs’ Ages of Globalization, guided the research question.

Beyond The Classroom: Leveraging P-12 Education Brand Equity To Cultivate Community Capitals And Drive Economic Growth In Rural Mississippi, Patrick Braden Miller

Theses and Dissertations

This dissertation explores the relationship between education brand equity and community-economic development in rural Mississippi as a result of a consumer-oriented approach to education and manifested through the modern school choice movement. A survey of public school superintendents (n=28) found a statistically positive correlation, suggesting that a strong school brand leads to increased community-economic development. The Community Capitals Framework suggests this connection is due to interconnected capitals like human and social capital but helps other capitals rise as well. Additionally, superintendents overwhelmingly agreed collaboration between education and community-economic development is essential. The research also examined perceptions of school choice. Superintendents’responses …
