Perspectives Of Trauma Among Licensed Trauma Therapists: A Concept Mapping Study, Sean W. Bullock

Master's Theses

To address gaps between research and psychotherapeutic intervention for trauma and trauma-related issues, the current study elicited and analyzed the perspectives of licensed trauma therapists via a concept mapping process. A literature review was conducted to explore the history and limitations of trauma’s current medical use as outlined by Criterion A of posttraumatic stress disorder in the DSM-5-TR. To answer the research question regarding how practitioners understand trauma, the researcher recruited licensed trauma therapists (n = 17) to participate in concept mapping. Participants generated 126 unique statements, which they then sorted based on similarity and rated individually on importance. Hierarchical …

Prompt-Driven Tabletop Robotic Manipulation With A Structured Llm Interface And Visual Verification, Tomas Franco

Master's Theses

Creating a tabletop robotic manipulation system that connects language goals to robot actions is a challenging problem. Large language models can interpret mission objectives and reason through actions, but when placed directly in control of hardware they can produce hallucinated commands that result in unsafe behavior without the proper safeguards.

This thesis presents a constrained LLM-guided manipulation system built around the Quanser Qarm, a four degree of freedom manipulator with a mounted Realsense RGB-D camera and a gripper with readable current. Every decision made by the LLM planner is routed through a gated command interface that restricts the model to …

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 …

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 …

Interpretable Wellness Prediction From Passive Wearable Sensor Data Using Large Language Models, Cheng-Huan Yu

Master's Theses

This thesis presents a unified framework for multi-target wellness prediction using passive wearable sensor data and large language models (LLMs). The study integrates two complementary paradigms: prompt-based regression and representation-driven classification. In the first stage, structured wearable representations derived from daily physiological signals are used to prompt LLMs to predict stress, fatigue, sleep quality, and readiness. Two input representations are evaluated: statistical summaries and hybrid inputs combining statistical summaries with raw sensor values. To improve interpretability and prediction consistency, the second stage introduces a representation-centric classification framework in which wearable signals and wellness targets are discretized into categorical levels. Multiple …

Monoids With K-Strictly Local Geodesic Languages, William M. Hong

Master's Theses

A paper by Gilman, Hermiller, Holt and Rees (2011) prove that a group G finitely generated by X is virtually free if and only if the language of geodesics words in G over X is k-strictly local if and only if the word problem is context-free. If M is a monoid finitely generated by X, we define Γu(M,X) to be the underlying, undirected graph of Γ(M,X). We prove that if the language of geodesics in Γu(M,X) based at the identity is k-strictly local, then the monoid and semi-group word problems are context-free.

Perceptions Of Speech-Language Therapy Among Generations Of One Mexican-American Family, Sabrina A. Macias

Master's Theses

This research is a modified replication of Salas-Provance et al. (2002) and analyzes the perceptions of speech-language therapy among one Mexican-American family. It investigates opinions about causes of speech-language disorders, for whom speech therapy can be helpful, characteristics and stereotypes about people with hearing and speech disorders, and the influence of education level on such opinions. With the assistance of three family members and two cultural informants, an online survey was developed consisting of demographic factors, Mexican folk and medical beliefs, and potential stereotypes of people with speech, language, and hearing disabilities. Twenty-three family members (response rate = 76.7%) completed …

Pick Up The Pieces: Multicultural Men’S Experiences Of Represenentation And Belonging In Higher Education, Lucion Armani Fuller

Master's Theses

To examine how multicultural students experience identity, representation, and belonging within U.S. higher education structured around monoracial classification systems, the present study interviewed six self-identified multicultural male college students. Drawing on Frantz Fanon’s concept of identity fragmentation and Critical Multiracial Theory, the study explored how institutional categorization and racialized perception shape lived experiences of identity formation and misrecognition. Using semi-structured interviews and reflexive thematic analysis informed by interpretive phenomenology, participant narratives were analyzed to understand how identity is negotiated within institutional spaces. The study has three themes. The first is experiencing imposed identity and racial misrecognition. The second is navigating …

“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 …

Trace: Temporal Rhetorical Analysis And Consistency Evaluation For Legislative Speech, David Hernandez

Master's Theses

Legislators frequently discuss the same policy issues across multiple hearings and legislative sessions, sometimes maintaining consistent positions and other times modifying or reframing their stance over time. Understanding how these positions evolve is important for analyzing political discourse and democratic accountability, yet identifying such shifts at scale remains difficult.

We introduce TRACE (Temporal Rhetorical Analysis and Consistency Evaluation), a system built on the Digital Democracy Database (DDDB) for detecting rhetorical inconsistency in California legislative hearing testimony. TRACE organizes utterances into speaker-anchored timelines indexed by bill and session, then applies hybrid semantic retrieval — combining dense BGE embeddings with BM25 lexical …

From Seizure To Settlement: Liberated Africans, Imperial Law, And Labor In The Indian Ocean World, 1810–1860, Holly S. Mcfate

Master's Theses

This thesis examines the relationship between British antislavery, imperial law, and labor management in the western Indian Ocean during the first half of the nineteenth century. Centered on the 1821 capture and condemnation of the slave schooner Industry by HMS Menai, the study employs a microhistorical methodology to reconstruct the legal and administrative processes that governed the lives of Africans seized from slave ships after their liberation. Drawing upon Vice-Admiralty Court records, Colonial Office correspondence, naval logbooks, and administrative registers from The National Archives (UK) and the Mauritius Archives, the thesis follows the transition of captive Africans from maritime interception …

Perception Is Reality: Evaluating Transportation Satisfaction And Utilization In Continuing Student Housing At Cal Poly, Lucas Owens

Master's Theses

As higher education institutions increasingly mandate on-campus living to foster student success, the built environment becomes a critical determinant of daily mobility. California Polytechnic State University (Cal Poly) is transitioning to a two-year residency requirement and tightening vehicle restrictions. This thesis evaluates how the spatial and built-environment realities of peripheral housing complexes in Cerro Vista Apartments and Poly Canyon Village shape student transportation satisfaction and utilization, and emergency evacuation preparedness.

Employing a mixed-methods approach, this research triangulates data from 79 student surveys and 10 semi-structured interviews. The findings indicate that supplementing traditional metrics of proximity with localized spatial data presents …

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 …

Cyberspatial Cartographies: Mapping Digital Nationhood Within The California-Punjabi Diaspora., Saihajpratap Singh Bajwa

Master's Theses

This research investigates the phenomenon of digital nationhood, the idea that a new form of community is actively produced through interactions taking place within digital social networks and forums. These spaces function as more than repositories of information or cultural archives; they are living ecosystems in which identity is constructed through mutual encounters among members of a diaspora, where shared references, meanings, and concepts proliferate across multiplex networks. The central questions animating this inquiry are: can a nation exist without a territory, and are these encounters producing what we might conceive of as a digital nation?

The Punjabi people serve …

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 …

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, …

A Novel Approach To Creativity Assessment: Forced Pairwise Ranking With Large Language Models, Phillip R. Gregory Jr

Master's Theses

Assessing creativity at scale remains a persistent challenge in cognitive science, as human raters are costly, slow, and often inconsistent in their judgments. This thesis introduced a novel framework for automated scientific creativity assessment using forced pairwise ranking, in which fine-tuned large language models compared response pairs and determined which was more creative. Five empirical studies were conducted using Llama-2-7B and Llama-2-13B models adapted via LoRA fine-tuning and benchmarked against human scored responses from the Scientific Creative Thinking Test. A regression baseline achieved Pearson �� = .74 on the test set, matching the human inter-rater ceiling reported in the literature. …

"Ostracized As We Are With God": Mina Loy's Anti-Career And The Search For Originality, Peyton L. Phillips

Master's Theses

Among many modernist artists, Mina Loy remains one of the most complex and allusive. Recent posthumous exposure of Loy's life and work adds to this precarity. A significant piece of Loy's life that is especially complex to contemporaries is her time spent writing. By establishing Loy's subjective relationship with her Victorian upbringing, this paper seeks to show examples of its influence on her search for originality. Mainly, the paper examines Loy's concept of originality, where that concept may have come from, and how it is reflected in her literature. The paper analyzes three of Loy's literary works, her poems "Virgins …

Investigating Racial And Ethnic Differences In Help-Seeking Recommendations And Intentions For Posttraumatic Stress Symptoms And Symptom Clusters, Josselyn Yanisbeth Telule

Master's Theses

Racially and ethnically minoritized (REM) communities experience disproportionate exposure to adverse events, including discrimination, socioeconomic disparities, justice system involvement, and limited access to healthcare. These inequities increase the likelihood of experiencing potentially traumatic events (PTEs) and developing trauma-related mental health concerns such as posttraumatic stress symptoms (PTSS). Despite this elevated risk, REM populations consistently underutilize mental health services. Although several explanations have been proposed—including differences in symptom recognition, perceived need for care, cultural values, mental health literacy, and preferred sources of support—less research has examined racial and ethnic differences in help-seeking intentions (HSI) and help-seeking recommendations (HSR), particularly in response …

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 …

Probing Representational Emergence In Large Language Models, Shawn Ismail

Master's Theses

This thesis investigates whether abrupt behavioral gains in large language models under scaling are accompanied by systematic changes in internal representations. It combines a behavioral screen of 65 tasks per family with targeted layerwise probing across eight decoder-only, open-weight model families. Behavioral emergence is defined for each family-task trajectory using an empirical jump detector, with segmented regression retained only as a diagnostic. The representational follow-up analyzes 27 selected MMLU subtasks shared across all families, spanning 37 checkpoints and 216 family-task units.

For each follow-up checkpoint, frozen linear probes are trained on every layer's hidden states to measure how much task-relevant …

Preserving Cherokee Culture Through Literacy And Literature: A Study Of Gendered Literacy, Rhetoric, And Cultural Continuity In The Cherokee Nation, Diana W. Baber

Master's Theses

Early explorers to what is now America, beginning with Hernando DeSoto in 1530, stole the dignity and the lands of the Indigenous peoples of America, of whom the Cherokees are only one nation. Two of the things that could not be taken was the Cherokees’ rich cultural tradition and oral histories. Stories passed orally from generation to generation to ensure that histories were preserved. They were largely preserved by the women of the tribe.

After the American Revolution, there was pressure from the new government to force the Cherokees to assimilate to the new American culture—to speak English, dress and …

Developing A Vietnamese Text Summarization Large Language Model On Limited Hardware, Tin Pho

Master's Theses

Text summarization models have achieved significant growth during the last few years because of major Large Language Model (LLM) technological advancements. The application of LLMs are widely used in news distribution (TL;DR news), translation tools (DeepL Translate), or virtual assistants (ChatGPT, DeepSeek, Claude, etc.). However, the progress has not yet reached all languages equally. The Vietnamese language is used by more than 90 million people, but the language is not as highly developed for LLM as it has many homophones, five different tones that affect meaning of words, and irregular grammar compared to other languages (e.g. English, Spanish, etc.). Also, …

Bicultural Identity, Work-Life Balance And Mental Health Outcomes In Swana Students, Julie M. Salama

Master's Theses

Southwest Asian and North African (SWANA) college students navigate academic demands alongside immigration-salient stressors that may shape their mental health and academic performance. This study examined generational status (Gen 1 vs. Gen 2+), identity conflict, ethnic identity, and work–life balance (WLB) in overall GPA and major GPA, and mental health outcomes of depression (PHQ-9), and anxiety (GAD-7) among SWANA students (N = 35). Two one-way MANOVAs found no generational differences for academics (overall/major GPA) or mental health (PHQ-9/GAD-7). Identity conflict was unrelated to GPA or symptoms but was positively associated with ethnic identity, while WLB was negatively correlated with depression …
