Examining The Ligands, Location, And Function Of Toll-Like Receptor 10, Kiefer Keanu Tam

Master's Theses

Toll-like receptors are a class of innate immune pattern recognition receptors that detect pathogen-associated molecular patterns and regulate downstream inflammatory responses. Toll-like receptor 10 remains the only human TLR whose ligand specificity, cellular localization, and immunological function are not fully defined. Emerging evidence suggests that TLR10 may play an anti-inflammatory role and can heterodimerize with TLR2 to modulate immune signaling. Previous studies from our laboratory demonstrated that stimulation with heat-killed Mycobacterium tuberculosis promotes TLR2-TLR10 heterodimerization and trafficking to the cell surface. In this study, we expanded our ligand panel to include additional gram-positive bacteria, particularly anti-inflammatory probiotic species, to further …

Hidden Behind Happiness: Bhutan’S Global Image And Ethnic Exclusion, Deepesh Das Shrestha

Master's Theses

Bhutan has gained international recognition for its philosophy of Gross National Happiness (GNH), which promotes holistic development through principles of well-being, environmental sustainability, cultural preservation, and good governance. Yet this celebrated image conceals a darker history: the systematic expulsion of the Lhotsampa, the Nepali-speaking ethnic minority of southern Bhutan. This study critically explores the contradiction between Bhutan's international image as a model of happiness and the lived experiences of Lhotsampa refugees who were displaced during the early 1990s.

Using a qualitative phenomenological research design, the study draws upon in-depth semi-structured interviews with six resettled Bhutanese Lhotsampa refugees living in the …

The Effects Of War Exposure On Psychological Well-Being And Social Preferences, Jacinta B. Duncan

Master's Theses

Using original survey and experimental data collected in Ukraine in 2023 and 2024, this paper estimates the causal impact of exposure to war-related violence on psychological outcomes, social preferences, and cognitive functioning. I combine a disaggregated war experience index with two incentivized economic experiments - a modified Dictator Game and an Emotional Stroop Test - and exploit randomized variation in task order as a priming treatment to establish causal identification. I find that war exposure has clear and consistently negative effects on psychological well-being, with direct personal experience producing the largest reduction in DASS well-being (β=−0.338 SD, p < 0.01), and that these effects are broadly distributed across demographic groups - though women report disproportionately higher psychological distress even at low levels of exposure. Social support emerges as the most effective buffer against war-related psychological harm, nearly eliminating the well-being gap between high- and low-exposure individuals, while economic hardship compounds distress and drives passive coping responses. In contrast, war exposure has limited and context-specific effects on social preferences: property loss and direct exposure increase prosocial behavior, but only when sharing is costless, consistent with solidarity norms operating within binding resource constraints. Cognitive task performance is largely unaffected by war exposure or emotional priming, with education emerging as the dominant predictor of Stroop performance across all specifications. Taken together, these findings support targeted, gender-sensitive mental health interventions and community-based support programs as high-leverage instruments for mitigating the long-term human costs of conflict.

Flowing Borders: U.S. Border Externalization In Latin America And The Los Angeles Declaration On Migration And Protection, Magdalena Olvera Hernandez

Master's Theses

In recent years, Latin America has emerged as a central transit region for extracontinental migrants originating from Africa, Asia, and the Middle East who seek to reach North America through alternative routes. This thesis examines the Los Angeles Declaration on Migration and Protection, among other regional migration governance frameworks that have reshaped migratory flows, state responsibilities, and protection outcomes in the Western Hemisphere. Focusing on the Darién Gap as a strategic chokepoint, the study analyzes the effects of coordinated migration policies, border externalization, and differentiated state roles on extracontinental mobility.

Drawing on official migration statistics from Panama, the United States, …

Asian American Multiraciality And Cultural Wealth In Higher Education, Marielle Song Lyons

Master's Theses

Multiracial Asian American college students endure pervasive and commonplace monoracism, multiracial microaggressions, and deficit-based narratives in higher education, which negatively impact their sense of self, belonging, and mental health. Through narrative methodology, the present qualitative study captures the stories of three multiracial Asian American undergraduate students and how they are making sense of their racialized experiences and cultural wealth in higher education. The results of this study suggest that (a) multiracial Asian Americans experience monoracism and multiracial microaggressions, which shape their understanding of cultural legitimacy and impact their behavior, sense of self, and relationships with others; (b) monoracism and multiracial …

Paternal Investment And Labor Market Soft Skills: Evidence From The Philippines, Timothy Crane Wilkins

Master's Theses

Fathers’ involvement in their children’s lives may shape the social skills that determine labor market success, yet evidence from Southeast Asia remains limited. This study examines the relationship between paternal investment and soft skills used in the workforce. Using original survey and experimental data from more than 300 parents of young children in Metro Manila, Philippines, I analyze how their fathers’ past involvement during childhood, and current involvement as grandparents in childcare relate to dictator-game giving, interpersonal trust, and workplace relations. The results indicate that paternal investment is most statistically significant with improved workplace relations, specifically with participants’ reported ability …

Meeting Their Needs: Experiences Of Uc Berkeley International Graduate Students Navigating Financial Strain, Ryann M. Hirt

Master's Theses

Of prior research on student experiences with financial strain, little has specifically focused on international student experiences in higher education while studying in the U.S., in tandem with financial strain. This qualitative study, through utilization of narrative methodology, explores the ways in which international students–in particular, graduate students–experience and navigate financial strain during their studies at a large, R1: Doctoral university: the University of California, Berkeley. The research was guided by three questions: (a) What are UC Berkeley international students’ stories of navigating financial strain? (b) What are the experiences of UC Berkeley international students with external and internal (campus) …

Building Cultural Wealth: A Look Into The 40x40 Council’S Rise East Plan, Camille L. Batiste

Master's Theses

This research began as an effort to understand how community-based organizations in neighborhoods that have experienced generational economic disinvestment address the financial and cultural wealth gap in their communities. With the 40x40 Council and its work in East Oakland serving as the case study, it is evident how this organization mobilizes to reverse the impact of cultural erasure and wealth exclusion, helping Black residents not just live, but thrive. With an enriched understanding of how the 40x40 Council frames its approach, implements its vision, and develops its longevity, the Rise East Plan utilizes an alternative wealth-building strategy that centers community, …

Ecological And Nutritional Drivers Of Floral Fidelity In Wild Pollinators, Adelaide Elise Ergastolo

Master's Theses

Plants must receive pollen from the same species in order to successfully reproduce. For most flowering plants, the transfer of pollen occurs via animal pollinators while they forage on plants to obtain food. Therefore, the fidelity of pollinators to individual plant species during foraging trips is directly related to the amount of conspecific pollen plants receive. Low floral fidelity of pollinators can reduce plant reproductive success, which in turn has the potential to lower food resources for pollinators in the future. While many factors can potentially influence pollinator floral fidelity, several important ones may be the nutritional resources provided by …

Vietnamese American Anti-Imperialism: South Vietnamese History And Analysis Of Publications Pre-1975, Jeannie Nguyen

Master's Theses

During the Vietnam War, citizens contested US imperialism at multiple levels. In South Vietnam, citizens published newspapers and magazines to challenge their government and expose the depth of US aggression in South Vietnamese society and culture. Inside the imperial core, Black, Chicano, and Asian American activists formed solidarities to resist the war and challenge racial inequality. At the intersection of imperialism inside and outside its borders, lies a group of South Vietnamese students and scholars who became American, migrating during the war via state-structured projects. However, in response to the heightening of war and drawing inspiration from their ‘Third World’ …

Effects Of A Basketball Match On Heart Rate Variability In Collegiate Intramural Players, Unobatsha Mbaiwa

Master's Theses

Heart rate variability (HRV) is a standard non-invasive physiological marker used to asses the autonomic nervous system (ANS) function and cardiovascular adaptability. HRV reflects the natural variations in time between successive heartbeats (R-R intervals), which come as a result of the interaction between sympathetic and parasympathetic branches of the ANS (Shaffer & Ginsberg, 2017). Higher HRV compared to an individual's baseline is normally considered an indicator of greater parasympathetic (rest/digest) influence and more effective physiological recovery, whereas lower HRV relative to baseline is associated with sympathetic (fight/flight) dominance, fatigue, and increased physiological strain. Since the standardized HRV measurement criteria were …

The Undaunted: How Young Adult Activist Literature Depicts The Fight For Social Justice, Emma Stack

Master's Theses

In this thesis, I will explore a wide range of young adult fiction novels that feature themes surrounding activism. My goal will be to use a number of novels to illustrate the importance of analyzing literature that features young people as activists within social justice movements. My main overarching question is: How are young people represented as activists in young adult literature, and how can young people use such literature as a catalyst for social change? I also plan to explore questions relating to how young people are represented as activists, why their voices are so integral when promoting social …

Sull'essere Umani "On Being Human", Benjamin S. Woodard

Master's Theses

The thesis describes the essential parts of the compositional process and how music expresses the individual philosophies of the composer. The goal is not to describe an overarching, and therefore overbearing, ruleset for what makes the compositional process human, but to describe it in relation to personal experience, with the rise of large language models in mind—sprouting from this research, composing a piece of music that reflects both the new electronic music that has now been embedded academically and the centuries-old tradition of performing on analog instruments. “Sull’essere Umani,” the English translation being "On Being Human", was the piece that …

Humor And The Politics Of Belonging: Race, Gender, And Radicalization In Online Spaces, Reese Chatman

Master's Theses

This thesis argues that post-ironic and meta-ironic humor acts as an affective gateway to far-right radicalization within online masculine subcultures. Examining incel forums and Groyper spaces, it traces how humor operates as the architecture through which extremist ideology is introduced, normalized, and internalized. Drawing on a synthesis of meme studies, digital rhetoric, and theories of irony and affect, and using digital ethnography and critical discourse analysis, the study examines recurring meme figures, especially the Wojak and its NPC variant, as portable diagnostic devices that sort participants into the "awake" and the unconscious regardless of ideological content. Case studies include incel …

Culturally Inclusive Usability Engineering (Ciue): A Framework For Evaluating Cultural Inclusion In Study Abroad Platforms, Louis Muhammad

Master's Theses

Study abroad programs provide students with opportunities to develop global com- petence and intercultural understanding. However, the digital platforms that support these programs often fail to communicate information that reflects the cultural and faith-based needs of diverse student populations. While prior research in Human-Computer Interac- tion (HCI) and usability engineering has explored cross-cultural and accessible design, cultural and religious considerations are rarely integrated into usability engineering pro- cesses. This thesis introduces the Culturally Inclusive Usability Engineering (CIUE) frame- work, which extends traditional usability engineering by integrating culturally informed con- siderations into the system development lifecycle. CIUE begins by identifying the …

Extracting California's Land Grant History: A Comparative Study Of Rule-Based And Llm Methods For Historical Document Processing, Anthony Colin Herrera, Anthony Colin Herrera

Master's Theses

This thesis explores methods to extract structured data from historical documents, making them more accessible for analysis and visualization. The goal is to provide historians and Digital Humanities scholars with tools that save time and reduce the manual effort required for this kind of research. We work with census records and historical texts from the Early California Population Project and Spanish Colonial census, covering California's 18th-19th century transition from Spanish and Mexican control to U.S. statehood. The system has three components: person matching across records, family tree generation, and land grant extraction. For person matching, we use a modified Levenshtein …

Programmable Degradation Of Polyethylene Via Amide-Functionalization: A Dual-Path Strategy Combining Palladium-Catalyzed Copolymerization And Enhanced Microbial Breakdown, Safi-Dapetel Balkissou Wouna

Master's Theses

Polyethylene (PE) is one of the most widely used polymers due to its durability, low cost, and chemical stability; however, these same properties contribute to its persistence in the environment. It takes about 1000 years for PE to be degraded by microbes in nature. This study investigates a molecular design strategy to enhance the biodegradability of PE by introducing polar functional groups into its backbone through palladium-catalyzed copolymerization with a Vince lactam-derived comonomer. This strategy was inspired by our previous observation that PHEVD (poly[7-(2-hydroxyethyl)-2,4-divinyl-3-oxa-7-azabicyclo[3.3.0]octane-6,8-dione]), a newly synthesized petroleum derived polymer that is rich of amide group, can be near-completely degraded …

Use Of Diamond™ Nucleic Acid Dye To Identify Trace Dna On Simulated Restraint Evidence, Elizabeth M. Gallardo

Master's Theses

This study aims to test the effectiveness of Diamond™ Nucleic Acid Dye (DD) in an operational casework study. By sticking to the exterior of cellular material in damaged cells or by incorporation into nuclei in undamaged cells, trace DNA molecules are visualized through the fluorescence of DD. DD offers a possibility to more easily recover crucial trace DNA of evidentiary value by improved visualization of the DNA on surfaces. While DD is an emerging material that is gaining traction in the research world, past studies haven't looked at DD in a more operational casework setting. To meet this demand, this …

Lateral Thinking In Large Language Models: Benchmarking And Fine-Tuning For Puzzle Solving And Generation, Ashish Khadka

Master's Theses

Recent progress in large language models has produced reasoning-oriented systems that allocate additional computation at inference time (e.g., deliberation, verification, and self-correction), raising the question of whether these gains can solve tasks requiring creative and lateral thinking. In this thesis, we study such capabilities using two popular word-association games—LinkedIn Pinpoint and New York Times (NYT) Connections—which require identifying non-obvious patterns or relationships. We first benchmark some light-weight open models and analyze their performance trends with respect to puzzle release dates and approximate model knowledge cutoffs to distinguish memorization effects from genuine inference. Our results show that accuracy of traditional embedding-based …

Extraction And Detection Of Α-Amanitin From A Gummy Matrix, Abigail Van De Water

Master's Theses

As a species, there is no mushroom family more deadly than the Amanita family, with most deaths being attributed to the mushroom A. phalloides. Its deadliness comes from a class of chemicals called amatoxins. These cyclic polypeptides (a, . and y) inhibit the function of RNA polymerase II which shuts down protein production in cells. Victims exhibit gastrointestinal issues followed by live failure, multiorgan failure, and eventually death if not treated. As interest in mushroom foraging increases, so does the potential for accidental poisoning based on misidentification. Another growing trend is people turning mushrooms into gummy candy, whether it be …

Snp Recovery And Eye Color Prediction Accuracy From Exogenous Human Hair: Evaluating The Impact Of Hair Color And Shaft Location, Kaitlyn Bennett

Master's Theses

Forensic science increasingly relies on DNA evidence; however, traditional short tandem repeat (STR) analysis has limitations when applied to degraded samples, such as hairs in the exogen phase. This preliminary study investigates the recovery and prediction accuracy of IrisPlex single nucleotide polymorphisms (SNPs) from exogen-stage human hair samples to determine how factors like hair color and shaft location influence SNP recovery and phenotypic eye color predictions. The analysis focuses on the IrisPlex SNPs rs12913832 (HERC2 gene) and rs1800407 (OCA2 gene), which are strongly associated with eye color variation. Hair samples were collected from twelve donors aged 18-26, representing natural brown, …

Hormonal, Cytokinetic, And Skeletal Response To A Single Weighted Vest Exercise Treatment: A Pilot Study To Determine Weighted Vest “Rucking” Treatment For Osteoporosis In Post-Menopausal Women, Eleanor Pell

Master's Theses

Osteoporosis is characterized by a deteriorating of bone tissue leading to brittleness and increased fracture risk that affects both men and women as they age. Postmenopausal women are of particular interest due to high risk of declining bone density, a characteristic of this population. Treatments for osteoporosis range from menopause hormone therapy, bisphosphonates, biologics, nutritional changes, and exercise. Load bearing exercise interventions have shown effectiveness for stimulating bone growth, but many factors such as lack of access, motivation, self-confidence or knowledge, prevent long term compliance. “Weighted vest rucking” refers to a variation of rucking, which is a form of exercise …

Companion Parrot Vocal Learning And Reproduction Of Human Speech Sounds, Karla Vilches Castaño

Master's Theses

Vocal learning is rare among animals but is well developed in parrots, which can imitate novel sounds and, in captive settings, reproduce human speech. This study helps address a larger evolutionary question about vocal learning. Specifically, whether vocal learning ability is best understood as a single generalized trait or as a multi-dimensional system in which different acoustic features can be learned and reproduced with varying degrees of fidelity. This thesis quantifies how closely companion parrots match their human tutors across three acoustic dimensions (spectrographic structure, intensity contour, and pitch contour) and tests whether mimicry accuracy varies among individuals, differs between …

Investigating The Taxonomic Uncertainties Of Potentilla Rupincola, Natalie Elizabeth Hieber

Master's Theses

Landscape stewardship is an integral role for land managers that becomes more important when rare or endangered species occur within managed areas. Conservation across the landscape is a primary concern for land managers, but resources allocated for conservation can be limited due to many competing goals. Taxonomic uncertainty surrounding rare and endangered taxa, particularly plant taxa, that have historically been classified solely using morphological features further complicates conservation planning. One such taxon is Potentilla rupincola, a rare plant endemic to the eastern Rocky Mountains in Colorado. For over a century, botanists have debated whether P. rupincola is a distinct species …

Although there is a gap in research, it is believed that …

Comparative Development Of Mof‑Based And Mof‑Free Agnp Functionalized Zno Nanorod–Cotton Fabric Composites For Photocatalytic Applications, Md Al Mamun

Master's Theses

Photocatalysis offers a cost‑effective and environmentally friendly strategy for degrading organic pollutants and addressing energy and environmental challenges. This study initially explored MOF‑based cotton‑fabric‑supported ZnO nanorod composites but found that the MOF component primarily acted as an adsorbent rather than an effective photocatalyst. Consequently, MOF‑free composites were developed by directly growing ZnO nanorods on cotton fabric and functionalizing them with silver nanoparticles. Photocatalytic testing revealed that AgNP‑modified ZnO nanorods, particularly at 10 mM AgNP, exhibited superior dye degradation efficiency, thereby demonstrating a scalable and effective photocatalytic platform.

Morphological Variation Of Lingual Glands In Wild American Alligator (Alligator Mississippiensis) Populations, Benjamin Angalet

Master's Theses

American alligators (Alligator mississippiensis) inhabit diverse aquatic ecosystems including freshwater wetlands, swamps, and estuarine rivers. As apex predators, their physiological resilience has implications for ecosystem stability and long-term conservation. With projected sea-level rise and increasing saltwater intrusion into coastal freshwater habitats, understanding the osmoregulatory capacity of alligators is increasingly important. Unlike marine-tolerant crocodilians such as the saltwater crocodile (Crocodylus porosus), which possess specialized salt-secreting lingual glands in addition to renal and cloacal mechanisms, the morphology and physiological significance of lingual glands in wild American alligators remain poorly understood. This study examined lingual gland morphology and plasma …

Performing The American Dream: Passing And Identity In The Great Gatsby (1925) And Passing (1929), Olivia O'Sullivan

Master's Theses

In this thesis, I explore how Jay Gatsby, protagonist in F. Scott Fitzgerald’s The Great Gatsby, and Clare Kendry, protagonist in Nella Larsen’s Passing, pass in order to achieve their American Dream. Both characters rely on carefully crafted identities to gain social mobility and access to worlds that would otherwise be out of their reach through the people they surround themselves with, their clothing, their mannerism, and even their intimate relationships. Throughout my close reading and analysis, I determine that Jay Gatsby and Clare Kendry’s attempts to pass to achieve the American Dream are futile, which demonstrates the idea that …

Effectiveness Of Quiz-Based Interventions In Virtual Reality Lectures On Learning, Mason T. Prather

Master's Theses

This thesis examined whether quiz-based interventions affect learning during an immersive virtual reality (VR) lecture and whether quiz timing strategy matters when prompts are delivered on a fixed timer or through gaze/Region of Interest (ROI)-based attention timing. The study used an eye-tracking virtual reality headset and a game engine-based classroom application. The final completed cohort included 29 participants assigned to three between-subjects conditions: No Intervention (n = 10), Timer-Based Intervention (n = 9), and Attention-Based Intervention (n = 10). All participants viewed the same virtual reality lecture and completed the same 15-item post-lecture assessment. Mean learning scores were 44.00% for …

Volunteer Spotlighting: Costly Signaling To Promote Volunteerism, Clyde A. Raible V

Master's Theses

Prosocial behaviors, because they are initially costly and do not guarantee a direct benefit to the actor, can nonetheless increase social status by signaling a willingness to incur cost on behalf of another. Given this signal value, nonprofit organizations may be able to leverage this knowledge to increase donations, such as through the provisioning of attention to, and recognition of, volunteers through social media. I predicted that the costliness of spotlighted behavior and the target signal clarity (i.e., individual vs. group spotlight) would interact with participants’ dispositional dominance and prestige-based status motives to influence volunteerism interest. To explore these associations, …
