Fear, Threat, And Google Searches: Examining Ideological Shifts Using Big Data, Erin M. Cerasaro

Master's Theses

In their review of research on factors that affect political conservatism, Jost et al. brought together research from several theoretical viewpoints. This produced a model of psychological needs and motives in individuals which react with stimuli that make them feel fearful and threatened (F/T), increasing adherence to conservative ideology. While some research supports these claims, evidence shows that in some contexts these variables increase ideological polarization overall, but may also have a greater impact on conservative attitudes specifically. Researchers have had difficulty in investigating these relationships in naturalistic settings due to an inability to manipulate events that precipitate this ideological …

Cultural Orientation, Parent-Child Connectedness, And Student Mental Health Perceptions, Abigail M. Mattias

Master's Theses

An individual’s perception of mental health is likely shaped by multiple interrelated factors. Connecting research into mental health perceptions across racial groups and parental value transmission suggests that a strong parent-child relationship increases the likelihood of the child endorsing parental and cultural values. The current survey examined the following predictors of mental health stigma among 144 college students: cultural orientation (collectivist/individualist attitudes), cultural background (collectivist/individualist heritage) as mediated by perceived parental mental health stigma, and parent-child connectedness as moderating the mediation. As predicted, there were stronger links between parent and child mental health stigma when parent-child connectedness was stronger. The …

Empathy As Activism: Empathy Fostering Tactics Of Minoritized Contemporary Artists, Nicole J. Rudolph-Vallerga

Master's Theses

In the 1980s to 1990s, movements emerged such as the U.S Multiculturalism Movement which responded to the Reagan era’s (1981-1989) conservate wave in the United States. Alongside these movements, many artists of minoritized identities (BIPOC, LGBTQIA+, women, disabled, etc.) were under attack and made art designed to inspire an empathetic response in the viewer as a form of defensive activism. These artists created art designed to protect themselves and their marginalized communities by provoking an empathetic connection between the viewer and the artist’s minoritized community to combat internalized stereotypes. I apply Heidi Maibom’s theory of “moral imagination” to activist art …

The Ecological Impacts Of Un-Protecting Forests: The Case Of Gold Mining In Ghana, Tate Alexander Barend

Master's Theses

This paper estimates the causal effect of Ghana’s Legislative Instrument 2462 (L.I. 2462) on deforestation in protected areas. The policy redefined the regulatory regime governing small-scale gold mining in protected areas, moving from prohibition to discretionary permitting. I exploit the implementation of L.I. 2462 as a policy shock and apply a difference-in-differences event-study framework to a propensity score–matched sample of pixels derived from high-resolution satellite images. Contrary to widespread concerns that the policy would accelerate deforestation, the results provide no evidence of large-scale vegetation loss in exposed protected areas following the policy change. Instead, protected area pixels located within 5 …

Differential Effects Of Generative Artificial Intelligence On Formative And Summative Assessment Performance: A Quasi-Experimental Longitudinal Study, Md Istiak Morsalin

Master's Theses

Generative artificial intelligence has unsettled a core assumption of course assessment: that scores on unsupervised work reflect what students can do unassisted. This study tests whether the widespread availability of ChatGPT altered student performance differently on formative versus summative assessments in Business Analytics and Foundations, a required undergraduate quantitative-methods course taught by one instructor across nine cohorts. In a quasi-experimental longitudinal design, the Fall~2022 cohort ($n = 90$), the last to finish before ChatGPT's public release, serves as a control against eight post-ChatGPT cohorts spanning Spring~2023 through Summer~2025 ($N = 646$). Outcomes were drawn from McGraw-Hill Connect records using matched …

Sentinel: Evaluating Occlusion-Centered Next-Best-View Selection Using Rgb-Derived Pseudo-Geometry, Paul Nassar

Master's Theses

Three-dimensional cameras provide direct geometric measurements, but their cost, weight, power requirements, and calibration constraints can limit their use in various lightweight or large-scale sensing systems. A potential alternative is to use conventional two-dimensional RGB cameras together with geometric reconstruction models that infer a partial three-dimensional representation from images. This thesis evaluates that possibility for next-best-view (NBV) selection through Sentinel, an occlusion-centered system for static, object-centric scenes with known camera poses and intrinsics. Sentinel converts source RGB observations into pseudo-geometry using monocular depth or point-map predictions, combines those predictions with camera-ray evidence, identifies occluded unknown regions, and selects a candidate …

Predicting Student Belonging In Computing Education: A Multimodal Machine Learning Approach Using Eeg And Survey Data, Hannah Moshtaghi

Master's Theses

Measuring students’ sense of belonging, characterized by feelings of acceptance, inclusion, and encouragement from teachers, remains a significant challenge in computing education. Prior research has associated this multidimensional construct with positive academic outcomes and has identified instructors’ growth- and fixed-mindset messaging as a potential influence. However, belonging is a complex and deeply personal experience that is difficult to capture through direct observation alone. Current measurement methods rely on self-report surveys, which may not capture every aspect of an experience that can also involve emotional and cognitive responses.

This thesis investigates whether combining EEG data recorded during a belonging questionnaire with …

Development And Evaluation Of Alternative Mandrel Materials For The Fabrication Of In-House Silicone Vascular Models, Cole Capitani

Master's Theses

Dr. Kristen Cardinal’s Tissue Engineering Laboratory at California Polytechnic State University, San Luis Obispo develops tissue-engineered blood vessel mimics (BVMs) for preclinical testing of neurovascular devices. These BVMs are reliant on silicone vascular models that define the vessel geometry, support endothelial cell attachment, and allow devices to be evaluated in a controlled in vitro environment. Previous work in the lab established injection molding as a viable method for fabricating silicone vascular models and utilized acrylonitrile butadiene styrene (ABS) for sacrificial mandrels. However, this workflow relied on the use of acetone for mandrel dissolution, required single-use mandrels, had extended post-processing times, …

Timelines Over Tokens: Summarization, Prompting, And Explainable Fine-Tuning For User-Level Suicide Risk Detection, Aditya Tekale

Master's Theses

This research presents a two-stage pipeline for user-level suicide risk detection from Reddit: first, inference-only prompting with summarization; second, fine-tuned encoder classification with explainability and expert validation. The data are user-level: each of the 500 C-SSRS Reddit items is one user’s chronologically concatenated posts and comments (a user timeline), annotated by psychiatrists. Stage one: six prompting strategies zero-shot, few-shot, chain-of-thought, tree-of-thought, least-to-most, and self-consistency are evaluated across six LLMs on multi-class and binary formulations; simple zero-shot achieves the highest balanced accuracy (0.53 multi-class). Error analysis shows longer inputs associate with misclassification (p = 0.002); domain-specific summarization (timelines >2,000 tokens) reduces …

The Relationship Between Strength Training And Burnout, Maddie R. Barrientos

Master's Theses

The purpose of this study was to comprehensively examine the relationship between strength training and burnout to assess whether consistent engagement in strength training would be associated with lower levels of burnout. Results of an online survey administered to 119 participants revealed that those who did strength train versus those who did not did not significantly differ in their levels of burnout, but among those who did strength training, there were significant differences in levels of burnout with how they engaged in strength training. The greater frequency of strength training participation and the greater number of muscle groups trained were …

Impacts Of Agricultural Microplastics On The Growth Of Marine Phytoplankton In Monterey Bay, Olivia A. Pawlyk

Master's Theses

Agricultural plastics are an emerging source of microplastics (MPs) to coastal marine environments, yet their effects on marine phytoplankton remain poorly understood. In coastal regions surrounding Monterey Bay (California, USA), plastic mulch used in agriculture can fragment into MPs during weathering and removal, entering marine waters via runoff and wind transport. This study investigated the effects of environmentally relevant concentrations of agricultural MPs on the growth and physiology of four marine phytoplankton species: two harmful algal bloom (HAB) taxa (Alexandrium sp. and Pseudo-nitzschia multiseries) and two non-HAB taxa (Thalassiosira sp. and Prorocentrum sp.). Each species was cultured independently and exposed …

Investigating Learning In Immersive Virtual Reality, Andrew Negrette

Master's Theses

Students often struggle with learning challenging subjects throughout their education. This also tends to lead to lower enjoyment and science self-efficacy for learning. Some subjects may be better represented in 3-dimensional spaces utilizing immersive virtual reality (IVR). Recently, IVR headsets have become more accessible and affordable and therefore are in wider use. The purpose of this study was to investigate whether differences in science selfefficacy, enjoyment, presence and knowledge retention exist between IVR and controls on an ocean acidification lesson. I predicted that participants taking the lesson in IVR would score higher compared to a laptop on all measures, due …

Superresolution Spectroscopy Of Atomically Thin Semiconductors And Moiré Heterostructures, Chien-Chu (Charity) Wei

Master's Theses

Atomically thin semiconductors and moir’e heterostructures provide an important platform for studying quantum phenomena shaped by reduced dimensionality, interlayer coupling, strain, and local structure. In MoS2, the transition from bulk to monolayer form changes the material from an indirect to a direct band gap, while stacked and strain-engineered systems can produce spatially varying moir’e potentials on nanometer length scales. Because these effects are highly localized, conventional far-field optical spectroscopy is often limited in its ability to resolve them directly. This thesis explores superresolution vibrational spectroscopy as a route toward probing local behavior in atomically thin semiconductors and moir’e heterostructures. Far-field …

Remote Reality: Exploring The Outcomes Of Psychological Contract Breach On Telecommuting Employees, Karen L. Ng

Master's Theses

The purpose of this study was to investigate the relationship between psychological contract breach (PCB) and attitudinal outcomes, specifically job satisfaction, organizational commitment, and turnover intent, within the telecommuter population. Results of an online survey administered to 213 participants revealed strong support of all hypotheses: PCB was negatively associated with job satisfaction and organizational commitment and positively associated with turnover intent. Exploratory analyses revealed moderating effects of remote work frequency and organizational tenure with PCB and attitudinal outcomes. High-frequency remote workers and longer-tenured employees showed stronger negative reactions to PCB, indicating their amplified vulnerability to breaches. Age and gender showed …

The Moderating Role Of Flexible Work Styles On The Relationship Between Relational Identification And Affective Organizational Commitment, Justine Lee

Master's Theses

The purpose of this study was to explore the moderating role of flexible work styles (in-person, hybrid, and remote) on the relationship between relational identification and affective organizational commitment (AOC). The study utilized an online survey to collect data from 69 respondents. The results demonstrated that although relational identification and AOC were related, this relationship was not moderated by flexible work styles. The three different work styles of in-person, hybrid, and remote work did not show differing affects for a subordinate’s relational identification and the strength of their AOC. The results emphasize that organizations can foster strong relational identification to …

The Moderating Effect Of Pay Satisfaction On The Relationship Between Generational Differences And The Desire For Meaningful Work, Mia J. Kottgen

Master's Theses

The modern workforce is increasingly generationally diverse, with generational cohorts such as Baby Boomers, Generation X, Millennials, and Generation Z differing in their work values and attitudes. Prior research suggests that meaningful work may be experienced differently across generations and that workplace factors, such as pay satisfaction, may influence these differences. However, few studies have examined generational differences in the desire for meaningful work while also considering workplace influences. The purpose of the present study was to examine the relationship between generational identity and the desire for meaningful work, and whether pay satisfaction moderates this relationship. A survey was administered …

The Relationship Between Imposter Syndrome And Organizational Citizenship Behaviors: The Moderating Role Of Gender, Sakina I. Read

Master's Theses

Prior research consistently shows that imposter syndrome is associated with a wide variety of negative psychological and work-related outcomes such as stress, burnout, and lower job satisfaction. However, other research suggests that individuals with higher levels of imposter syndrome may engage in compensatory behaviors such as increased effort and discretionary helping for impression management purposes. Additionally, research has found that women tend to report higher levels of imposter syndrome and higher engagement in organizational citizenship behaviors (OCBs) than men, suggesting a gender difference in both variables. The present study sought to examine the relationship between imposter syndrome and OCBs and …

A Socio-Ecological Study Of Coyote And Human Interactions In San Francisco Bay Open Space Preserves, Zhiyi Zhou

Master's Theses

Urban open space preserves support both intensive recreation and wildlife, but the information on carnivore activity and visitor perceptions is limited. This study combined camera-trap monitoring and on-site visitor surveys to evaluate activity patterns of medium- to large-bodied mammals and perceptions of coyotes at Windy Hill and Rancho San Antonio Open Space Preserves (South San Francisco Bay Area). From October 2024 to July 2025, thirteen cameras recorded 213,681 photo events; detections were standardized as detections per 1,000 camera-hours. Ten mammal species and two avian species were detected, including four focal carnivores: coyote (Canis latrans), bobcat (Lynx rufus), mountain lion (Puma …

Health Literacy, Health Information Seeking Behavior, And Vocal Hygiene Amongst Video Game Voice Actors In The United States, Wendy Lau

Master's Theses

Video game voice actors (VGVAs) perform vocally demanding tasks to bring video game characters to life, and are at high risk for voice disorders. This exploratory study aims to characterize vocal health in VGVAs by investigating the relationships between health literacy, health information seeking behavior, and vocal hygiene practices. Thirty-one VGVAs completed an anonymous online survey. Data were analyzed using a mixed-methods approach: quantitative health literacy scores were calculated, and qualitative data underwent inductive thematic analysis in NVivo. Results show that VGVAs are highly proactive with their vocal health due to their desire for career longevity and their professional vocal …

Adaptive Task-Driven Lidar Point Cloud Compression For Autonomous Driving, Su Hyun Kim

Master's Theses

Autonomous-driving systems generate large LiDAR point clouds, but compression can damage the sparse object-support structure needed by 3D detectors even when reconstructions appear visually plausible. This thesis asks whether adaptive LiDAR compression can preserve downstream detection better than uniform compression by allocating more fidelity to detector-relevant regions. The main study builds a mask-aware range-image codec with an encoder-decoder bottleneck, an importance head, and an adaptive quantization variant. It compares this adaptive variant package with a confirmed masked uniform baseline under one fixed RangeDet evaluation surface and one fixed KITTI validation subset. Two supporting studies bound the result: a projection-reconstruction PointPillars …

Extracellular Vesicle-Mediated Transfer Of Gsdme-Nt Pores As A Mechanism Of Inflammation Propagation, Bifeng Xiao

Master's Theses

Inflammasomes are multiprotein complexes that initiate inflammatory signaling through activation of caspase-1, cytokine maturation, and cleavage of Gasdermin D (GSDMD). Cleaved GSDMD forms membrane pores that contribute to cytokine release and pyroptotic cell death. Recent evidence suggests that extracellular vesicles (EVs) may facilitate the intercellular transfer of inflammatory mediators. This study investigated whether GSDMD N-terminal fragment (GSDMD-NT) associates with EV-enriched fractions and contributes to inflammation propagation. Doxycycline-inducible HeLa cells expressing FLAG-tagged GSDMD-NT were used to generate EV-enriched fractions. Western blot analysis detected GSDMD-NT-associated material within EV fractions, while EV marker analysis supported successful enrichment of EV-associated material. Exposure of recipient …

Dissecting The Discourse: Colin Kaepernick's National Anthem Protest And Conservative Media As Competing Racial Projects, Travis Moody

Master's Theses

This thesis examines the media portrayal of Colin Kaepernick’s protest against police brutality and racial injustice during the National Anthem in the 2016 National Football League (NFL) season. Using content analysis, I analyze why Colin Kaepernick protested in his own words and how conservative media outlets such as Fox News rearticulated and criticized his social justice stance as an unpatriotic denigration of the American flag and Star-Spangled Banner. As I further argue, social movements such as #BlackLivesMatter and the Colin Kaepernick-inspired “Take a Knee” movement represent a political project to inform racial discourse regarding racial injustice in the United States. …

Satisfaction With Caseworker Services And Child Outcomes For Youth In The Foster Care System, Taira Masuda

Master's Theses

Currently, there are approximately 400,000 children involved in the U.S. foster care system (U.S. Department of Health and Human Services, 2023). Youth involved in foster care experience challenges such as trauma, disruptions to their support system, academic disruptions, and additional public system involvement (Emerson & Lovitt, 2003; Fawley-King et al., 2017; Masuda & Helm, 2024; Modrowski et al., 2023). Considering this context, it is essential to increase efforts to reduce added distress and bolster supportive contexts for youth. Caseworkers are essential service providers for youth in foster care. Caseworkers provide support to youth and families through assessing needs, connecting families …

“Being An Arab Is Like Fighting For Your Joy”: Exploring Bicultural Identity, Racialization, And Psychological Well-Being Among Us-Born Arab Americans, Hisham Nsier

Master's Theses

Bicultural identity development in Arab Americans, who must manage sometimes conflicting cultural expectations, is understudied. Even less is known about Arab Americans born in the United States (US-born AA), who are American by birth yet are alienated from society due to differences between their ‘white’ racialization and their cultural identities. The current study aimed to examine the relationship between bicultural identity, racialization, and psychological well-being at the intersection of US-born AA’s co-existing identities. Eight adult US-born AAs (Mage = 28 years, SD = 4) were recruited from professional Listservs and WhatsApp affinity groups. Qualitative semi-structured interviews were conducted and analyzed …

Articulating The Future: How The Techno-Optimist Manifesto Constructs Ai Hegemony, Christian Noel Yeomans

Master's Theses

This paper analyzes two recently published digital manifestos—the Techno-Optimist Manifesto (TOM) by Marc Andreessen and the Bitcoin Whitepaper (BW) by Satoshi Nakamoto—and how they articulate political visions for the respective rising technologies of artificial intelligence (AI) and cryptocurrency. I apply Laclau and Mouffe’s discursive articulation theory to both manifestos, analyzing how they contribute to the formation of hegemonic ideological visions among the elites of these two technological sectors. In the context of AI elites, TOM transforms an existing Silicon Valley ideology, techno-optimism, into a radical new form of accelerationism, which I coin t/opt. This shift is examined within the context …

A Study On Quantization And Hardware Cost Tradeoffs In A 5g Nr Ldpc Decoder On Fpga, Giancarlo Acosta

Master's Theses

The fixed-point implementation of a 5G New Radio LDPC decoder forces a tradeoff between precision and hardware cost, governed by the variable node word length W_L, the check node message width W_R, and the normalized min-sum correction factor α. This thesis characterizes how these three parameters affect both error correction performance and FPGA resource utilization for an LDPC decoder on an established LDPC decoder architecture. A bit-accurate MATLAB core model records bit error rate (BER) and frame error rate (FER) while a verified HDL Coder model generates synthesizable VHDL for Vivado synthesis, and both are swept …

Evaluation Of Alternative Solvents For Electrospinning Occluded Scaffolds To Model Intracranial Atherosclerotic Disease In Blood Vessel Mimics, Olivia D. Rankin

Master's Theses

Intracranial atherosclerotic disease (ICAD) is characterized by a buildup of fatty plaque within the walls of arteries supplying the brain, resulting in vessel narrowing, restricted blood flow, and increased risk of ischemic stroke. While various treatments exist for ICAD, most are accompanied by high recurrent stroke rates and other adverse events, highlighting the need for further investigation and models for pre-clinical testing. Tissue engineered Blood Vessel Mimics (BVMs), consisting of a polymer scaffold sodded with human vascular cells, serve as physiologically relevant in vitro models for vascular device testing. This thesis focused on the application of alternative solvents to a …

Chemical And Sensory Consequences Of Oxidative And Reductive Handling Of White Wines, Amelia Pargellis

Master's Theses

In the 2024 and 2025 vintage four experiments were performed each with a different varietal, namely Albariño, Grenache blanc, Loureiro, and Vermentino. These experiments investigated the effects of hyperoxygenation, reductive winemaking techniques, while monitoring the oxidation-reduction potential.

Albariño grapes were made following two juice protocols, control/reductive (Reductive Control) and oxidative (HyOx). Reductive Control received antioxidants (50 ppm SO₂, 160 mg/L ascorbic acid) and CO₂ blanketing, and HyOx underwent hyperoxygenation at approximately 700 mL/L/h of air for two hours through a stainless-steel sparging stone with 10-µm pores. Juice was cold-settled and racked. Reductive Control juice was split into …

Ai Interview Helper: A Tool For Assisting Search And Rescue Long-Profile Interviews, Dylan P. Starink

Master's Theses

In Search and Rescue (SAR) operations, time pressure and limited interviewer experience can lead to missed opportunities when interviewing a missing person’s friends and family. This thesis presents a real-time, end-to-end system that provides context-aware follow-up question suggestions as interviews unfold. Leveraging large language models (LLMs) and agentic design patterns, the system is intended to support interviewers by helping them identify relevant follow-up questions and pursue potentially overlooked lines of inquiry.

The system was evaluated through three mock interviews with two SAR interviewer participants across two events. Given the limited sample size, the results provide early insights into the feasibility …
