Sam3-Litetext: An Anatomical Study Of The Sam3 Text Encoder For Efficient Vision-Language Segmentation, Chengxi Zeng, Yuxuan Jiang, Ge Gao, Shuai Wang, Duolikun Danier, Bin Zhu, Stevan Rudinac, David Bull, Fan Zhang

Research Collection School Of Computing and Information Systems

Vision-language segmentation models such as SAM3 enable flexible, prompt-driven visual grounding, but inherit large, general-purpose text encoders originally designed for open-ended language understanding. In practice, segmentation prompts are short, structured, and semantically constrained, leading to substantial over-provisioning in text encoder capacity and persistent computational and memory overhead. In this paper, we perform a large-scale anatomical analysis of text prompting in vision–language segmentation, covering 404,796 real prompts across multiple benchmarks. Our analysis reveals severe redundancy: most context windows are underutilized, vocabulary usage is highly sparse, and text embeddings lie on a low-dimensional manifold despite high-dimensional representations. Motivated by these findings, we …

Co-Designing With Autistic Livestreamers: Care, Constraints, And Trade-Offs In Livestreaming, Terrance Mok, Anthony Tang, Lora Oehlberg

Research Collection School Of Computing and Information Systems

Autistic livestreamers use platforms like Twitch for social connection, self-expression, and community, but these spaces also impose ongoing social and emotional demands. Prior work has documented these experiences, but less is known about what autistic creators themselves envision for the tools and platforms they use. We address this gap through a Research through Design (RtD) co-design study with three autistic Twitch streamers, using speculative artefacts as discussion prompts to explore how participants reasoned about potential livestreaming technologies. Across three co-design activities, we identify three overarching tensions shaping autistic streaming practice: Expression versus Misinterpretation and Harm; Public Participation versus Control and …

History To Future: Evolving Agent With Experience And Thought For Zero-Shot Vision-And-Language Navigation, Guangzhao Dai, Shuo Wang, Zihan Wang, Guo-Sen Xie, Yang Yang, Jinshan Pan, Qianru Sun, Xiangbo Shu

Research Collection School Of Computing and Information Systems

Vision-and-Language Navigation in Continuous Environment (VLN-CE) requires an agent to follow language instructions to navigate the target destination. With the advancement of large language models (LLMs), recent efforts have explored adapting them for zero-shot VLN-CE, offering a promising solution in addressing the drawbacks of poor generalization in the training-based paradigm. However, existing LLM-based works primarily perform naive reasoning for decision-making and lack feedback, e.g., reviewing historical errors and predicting future potentials. Consequently, it may suffer from continuous failure for those initial error tasks. In this paper, we rethink LLM-based zero-shot VLN-CE and propose a new paradigm, named EvoNav, to improve …

A Novel Hierarchical Multi-Agent System For Payments Using Llms, Donghao Huang, Joon Kiat Chua, Zhaoxia Wang

Research Collection School Of Computing and Information Systems

Large language model (LLM) agents, such as OpenAI’s Operator and Claude’s Computer Use, can automate workflows but unable to handle payment tasks. Existing agentic solutions have gained significant attention; however, even the latest approaches face challenges in implementing end-to-end agentic payment workflows. To address this gap, this research proposes the Hierarchical Multi-Agent System for Payments (HMASP), which provides an end-to-end agentic method for completing payment workflows. The proposed HMASP leverages either open-weight or proprietary LLMs and employs a modular architecture consisting of the Conversational Payment Agent (CPA - first agent level), Supervisor agents (second agent level), Routing agents (third agent …

Design And Optimization Of A Bluff Body For Energy Harvesting Of Transverse Galloping Induced By Low-Speed Wind Using Bernstein Polynomial Equations, Youssef Wael Abdelmoneim

Theses and Dissertations

In this thesis, a computational framework is proposed for optimizing the aerodynamic shape of bluff bodies used in galloping-based wind energy harvesters. The system targets low-wind speed environments, where normal wind turbines are not effective, offering a potential alternative to batteries used for powering small electronic devices such as wireless sensors. The design relies on the galloping effect, where airflow around a bluff body induces transverse oscillations that drive an energy conversion mechanism. To generate efficient bluff body geometry, the Class-Shape Transformation (CST) method is used to define a wide range of candidate shapes with minimal design parameters. These shapes …

Campus Community Vibes: How Queer Asian American Students Navigate Their Higher Education Experiences, Nathan Nguyễn

Dissertations

Misconceptions and stereotypes about Asian American college students include the belief that they are innately academically successful and that if Asian American students struggle, their challenges do not compare to their Black/African American, Hispanic/Latine, or Native American/Indigenous counterparts (Museus & Buenavista, 2016). Contemporaneous to this, lesbian, gay, bisexual, transgender, and queer (LGBTQ) college students experience interrogation, exploration, and various levels of support regarding their sexuality and/or gender identity. At this intersection, queer Asian American students must navigate campus settings that can enhance or diminish their agency for different facets of their identities (Crenshaw, 1991; Iftikar & Museus, 2018; Ray, 2019). …

Holding Space: How Caregivers Narrate Support, Stress, And School Partnership, Celia D. Davenport

Dissertations

This qualitative dissertation examined how caregivers of students with low-incidence disabilities experienced and interpreted school support within the context of daily family life. Grounded in the social model of disability, the study was designed to explore the nature of meaningful school-based support, the limitations caregivers encountered, and the ways school-family relationships shaped these experiences over time. The overarching research question asked how caregivers of students with low-incidence disabilities perceived the school’s role in supporting their families. A qualitative research design was selected to center caregiver voice and allow for in-depth exploration of lived experience. Data were collected through semi-structured interviews …

When Saying "No" Is Not Enough: Cognitive-Action Decoupling And The Illusion Of Safety In Llm Agents, Shasha Yu

School of Professional Studies

Current safety evaluations of large language models (LLMs) predominantly rely on textual compliance, implicitly assuming that refusal-style responses correspond to safe behavior. This assumption becomes fragile when LLMs are embedded in agentic systems with the ability to execute state-changing actions. In this paper, we present an empirical critique of text-centric safety evaluation through an action-aware study of LLM agents under controlled conditions. Across multiple state-of-the-art models, we observe a recurring cognitive-action decoupling: agents generate policy-aligned refusal language while still producing unsafe tool-mediated action proposals. This produces an illusion of safety, where conversational audits indicate compliance even as operational risk persists. …

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 …

Ecological And Political Grief In College Students: Making Meaning In Uncertain Times, Kate Hlad

University Honors Theses

The study aims to explore grief experiences of college students in relation to world issues, namely ecological and political concerns and ways of making/finding meaning, hope, and purpose. To address a gap in research on manifestations of combined and multifaceted world grief experiences, qualitative research was conducted in the form of semi-structured interviews with 6 different college students. Common themes arose from the interviewees' grief experiences including hopelessness, overwhelm, anger, and changed future planning. Additionally, participants shared their experience finding community, engaging in creative pursuits, and taking action against oppressive systems in order to experience hope and purpose individually and …

School Counseling With Indigenous Students In Rural America: The Role Of A Counselor In Supporting An Indigenous Pedagogy Based Curriculum, Donovan Greene

University Honors Theses

Indigenous students are a huge population that are not fully supported by the school psychology field. This is primarily due to cognitive imperialism and the focus on a Western monoculture in education. This has led school psychologists and counselors feeling underprepared and lacking the tools to work with Indigenous students and as a result these  students are harmed academically and in terms of their mental wellness. This essay opens with a literature review of scholarship on school counselors working with Indigenous students. To improve relations, I suggest implementing more culturally focused interventions. Unfortunately there is a lack of research on …

The Security Of Llm-Generated Code, Christopher Brian Gonzalez Ayala

Student Theses

The rapid adoption of Large Language Models (LLMs) in software development has transformed coding practices by enabling automated code generation, completion, and optimization. Despite these advantages, concerns persist regarding the security and reliability of LLM-generated code. This study presents a comprehensive evaluation of both the functional correctness and security of code produced by three prominent LLMs as of early 2026. A total of 4,800 code snippets were generated using 100 security-focused programming prompts derived from the OWASP Top 10:2025, translated across eight natural languages and two phrasing styles (literal and natural developer-oriented prompts). To assess performance, a multi-stage experimental framework …

Language Attitudes And Stereotypes Condition The Processing Of Contact-Induced Linguistic Variants, Sonia Barnes, Whitney Chappell

Spanish Languages and Literatures Research and Publications

This study examines the effect of language attitudes and stereotypes on vowel perceptions by two groups of listeners from Asturias, Spain that differ in their relationship with the languages present in their communities: Spanish, the national majority language, and Asturian, the regional minority language. The responses of 165 participants from the Nalón Valley (a mining area in the region) were compared with those of 156 listeners from Gijón (the largest urban area) as they categorized words containing synthesized productions of Spanish [o] and Asturian [u] in a task that combined binary forced-choice identification and visual priming. The results of a …

The Martha Wright-Reed Act: How The Fcc Took One Step Forward For Communication Equality For Deaf Individuals In Correctional Facilities And How It Could Be Expanded, Ashley Seebold

Seattle University Law Review

For decades, phone companies preyed on incarcerated individuals and their loved ones due to the lack of regulation of jail phone calls.2 In 2021, the average cost of a fifteen-minute jail phone call was about $3.3 In 2022, the average cost rose to $5.74, while some individuals faced an extreme charge of $24.82 for the same amount of time.4 In the early 2000s, consumer advocate and concerned grandmother Martha Wright-Reed called upon the Federal Communications Commission (FCC) to fix the imbalance so she could speak to her incarcerated grandson.5 Eventually, in 2023, the FCC answered her call to action and …

Linking (Imagined) Communities: World Language Students' Stereotypical Attributions To Native Speakers And Teachers Of German., Lucian Rothe

Faculty and Staff Scholarship

Abstract This study explores language learners' stereotypical descriptions of native speakers (NSs) of German and their relationship with participants' perceptions of teachers of German. It expands motivation research that employs stereotypes to gain insight into university students' views of target language (TL) speakers (Rothe, 2022, 2025). Sixty‐seven learners of German and 43 learners of other world languages (WLs) pro vided responses about NSs and instructors, while also rating the stereotypes' perceived accuracy. Participants held various stereotypical notions about NSs, reflecting broader societal narratives. Learners of German pro vided more detailed stereotypical descriptions. Both groups considered favorable stereotypes as more accurate …

From Framework To Practice: Insights About Aligning Foundation Impact And Strategic Positioning In A Trust-Based Philanthropy Era, Nancy Pole, Marie-Andrée Mbengue-Reiver, Anne Loranger-King

The Foundation Review

This article examines how a framework revealing foundations’ distinct orientations towards social impact has been used in practice, illustrating the tool’s utility and areas for refinement through one foundation’s experience.

Originally developed for Quebec’s philanthropic ecosystem, the heuristic positions foundations along two continua: strategic posture (problem-solving versus communitysupporting) and impact focus (grantee outcomes versus foundation outcomes), creating four impact orientation quadrants.

The case reveals productive tensions when different parts of a foundation occupy different quadrants. They are particularly acute for public foundations accountable simultaneously to donors, grantees, government funders, and communities.

These insights inform future framework iterations with a view …

Effectiveness Of Monetary Policy Communication: Evidence From Textual Analysis Of Daily Newspaper Articles, Bisrat Abebe Woldesilassie

Dissertations

Monetary policy communication has become a crucial tool for central banks to shape market expectations and enhance transparency. The goal of this paper is to measure how effectively the Fed communicates monetary policy through FOMC minutes by analyzing the impact of the release of FOMC minutes on financial markets through textual sentiment analysis of daily newspaper articles. I measure the surprise in the daily news sentiment that is caused by FOMC minutes release. The surprise in the sentiment is calculated as the change in the news sentiment that is measured over three weeks prior to the release of the FOMC …

"What Is That Data Really Telling You?": How Central Office Leaders Use Equity-Focused Data Practices To Rethink District Improvement, Nadine Sánchez

Theses & Dissertations

Public school districts face growing expectations to advance educational equity while operating within accountability systems that often prioritize measurable performance outcomes. Despite these expectations, less is understood about how central office leaders use data to support equity-focused systems change across schools. This critical exploratory case study examined how central office leaders in one public school district with an explicit commitment to equity used data to advance equity-focused improvement efforts. Guided by culturally responsive school leadership, coherence, and infrastructure of accountability frameworks, the study explored how leaders established a districtwide vision for equity, built capacity for data use, and used data …

“I” Or “We” In Times Of Crises: Should Marketers Use Individualist Or Collectivist Language When Times Are Tough?, Milad Hour, Golshad Parsimoghadam, Ali Jamei

Journal of Applied Marketing Theory

During the pandemic, as people dealt with fatalities, lockdowns, and the psychological impact of reduced social interactions, some marketing messages still captured significant public attention. What was the key element contributing to the success of these communications during such challenging times? This study focuses on the role of collectivism as a stress-coping mechanism included within marketing communications. Analyzing approximately 56,000 brand-generated posts on Platform X, the research examines how the use of collectivist language (e.g., we, us, etc.) relates to message likability, particularly as the pandemic nears its peak. The findings reveal that collectivist terms are positively associated with the …

Trans-Cyber Cinema: Digital Embodiment In Science-Fiction Films, Sophia R. Schrock

Dissertations, Theses, and Capstone Projects

This thesis aims to define the trans-cyber genre within cinema. By looking retroactively at a selection of nine films made across various decades and countries, this genre connects these films through their visualization and thematization of both trans and cyber embodiments, whereby the trans-cyber being emerges. Before the cinematic analysis and explanation of the three generic conventions selected for this thesis – transformation of body/gender; altered reality, memory, and temporality; and, radical death – the two intertwining theoretical frameworks will be established. This includes a brief summary of applicable transgender theory, and an introduction to cyborg theory (using Donna Haraway’s …

Exploring The Effect Of Babble Background Noise On Learning New Patterns In An Artificial Accent Of English In Monolingual And Bilingual Young Adults, Mariana Vasilita

Dissertations, Theses, and Capstone Projects

The current study examined how background noise affects the learning of novel phonetic and phonological patterns in speech. While prior research has shown that bilingual participants may learn new phonetic patterns more successfully than monolingual participants under quiet conditions, it remains unclear whether this advantage persists in more ecologically valid listening environments.

We investigated phonetic learning skills in monolingual English speakers (n = 13) and early bilingual speakers (n = 13). Participants were trained and tested on an artificial English accent presented in the presence of 12-talker babble noise (+10 dB SNR). A digit span task was also administered to …

Enhancing Ecological Validity In Speech-In-Noise Testing: Integrating Virtual Reality For A Multisensory Audiological Experience, Paulina Lee

Dissertations, Theses, and Capstone Projects

Despite the remarkable advances in hearing healthcare technology, the speech recognition tests used in routine clinical audiological assessment have remained essentially the same for decades.  Monosyllabic word recognition tests in quiet, such as the Northwestern University Auditory Test No. 6 (NU-6; Tillman & Carhart, 1966), have served as the audiology field’s default measure of speech understanding.  Modern speech-in-noise (SIN) tests, such as the QuickSIN (Killion et al., 2004), have emerged, yet they remain auditory-only, leaving an unignorable gap between what clinical tests measure and how patients communicate in daily life.  The present study examined whether pairing a standard SIN test …

Measuring Islamic Republic Propaganda In Western Media Coverage Of Iran: A Computational Framework, Leila Habibi

Dissertations, Theses, and Capstone Projects

Detecting propaganda is fundamentally difficult: effective propaganda must simultaneously conceal persuasive intent while achieving persuasive effect, which means that sophisticated propagandistic discourse necessarily occupies the ambiguous middle of a rhetorical spectrum rather than its obvious extremes. This thesis defines this property as the dual constraint problem and argues that it poses two challenges for the binary classification framing that dominates propaganda detection in Natural Language Processing (NLP). First, propaganda by definition does not come with clear labels: no propaganda arm willingly accepts the designation, so reliable ground truth does not exist at the source. Second, because the producer is actively …

Semi-Peripheral Whiteness In A Global City: Central And Eastern European Women In Dubai, Hana Rubenstein

Dissertations, Theses, and Capstone Projects

This capstone examines how Central and Eastern European (CEE) women navigate professional mobility in Dubai and asks to what extent Dubai enables them to bypass the post-socialist stigma attached to their semi-peripheral European identity. Situated at the intersection of migration studies, gender, and critical scholarship on semi-peripheral whiteness, the study addresses the limited attention paid to CEE women as economic actors outside European contexts, where they are often either absorbed into the category of “Western expatriates” or reduced to highly gendered stereotypes. Grounded in a qualitative, interpretivist approach, the study combines digital discourse analysis of 50 publicly accessible LinkedIn profiles …

G&P2p: A Multi-Source Approach To Grapheme To Phoneme Conversion, Chun-Yi Peng

Dissertations, Theses, and Capstone Projects

This thesis introduces G&P2P, a multi-source framework for grapheme-to-phoneme (G2P) conversion that integrates side pronunciations from multiple lexical resources. Unlike traditional single-source approaches, G&P2P fuses data from multi-sourced pronunciation dictionaries—including CELEX, PronLex, NETTalk, and WikiPron—through several fusion strategies. The goal is to improve model performance on out-of-vocabulary words through multi-source learning. Experiments were conducted with attentive LSTM, pointer-generator LSTM, and pointer-generator Transformer architectures. Models were trained on combinations of datasets and evaluated using word error rate (WER) across five random seeds.

Results show that fusing expert-curated dictionaries such as CELEX and PronLex consistently improves accuracy, achieving an 11.81-point absolute error …

Gremlin Theory: A Film Art Of Joe Dante, Frank Falisi

Dissertations, Theses, and Capstone Projects

This thesis seeks to establish the work of the filmmaker Joe Dante as a catalyzing and anarchic force let loose inside larger, dumber superstructures: linear narrativity, Hollywood, America, etc. It works to read the genre films he worked on—many of them made as popular entertainment for mainstream movie studios—as moments of actual subversion, allocating status quo (studio system) resources to create a biting-back against American imperial norms in the lingua franca of Marx and the Marx Brothers: gummy leisure-seeking stupidity and Gremlin transformation. This thesis seeks to argue that to understand Dante’s work is to understand pop transfiguration itself. This …

Unfreezing Language: A Decolonial Reframing Of Translanguaging Pedagogies In English As A New Language & Dual Language Bilingual Education Settings, Cristian R. Solorza

Dissertations, Theses, and Capstone Projects

This qualitative multi-case study examines how elementary teachers in English as a New Language (ENL) and Dual Language Bilingual Education (DLBE) settings conceptualize, implement, and reflect upon translanguaging pedagogies, with particular attention to translanguaging rings as tools for language differentiation. Grounded in a rearticulation of language as a dynamic, socially, politically, and historically constructed subject and object, this study challenges monoglossic ideologies that position named languages as bounded systems at the center of language education. Instead, it centers students’ lived, embodied, and agentive language practices as foundational to language learning and to their participation as knowledge producers in ENL and …
