Ten immigrant Latine participants, nine mothers and one grandmother, whose children attended traditional or charter elementary schools in one NYC district, shared their experiences through semi-structured interviews conducted in Spanish. Data were analyzed through iterative coding and thematic analysis …

Exploring Student Perceptions Of Culture Within An Algebra Unit: A Qualitative Action Research Study, Alesha Marie Love

Theses and Dissertations

Many barriers exist when teaching and learning mathematics. Although the mathematics curriculum is rigid and rigorous by design it is often not culturally relevant for the students engaging with the content. As a result, many students of color do not have an appropriate amount of representation to connect to a subject area that already seems exclusionary. This qualitative action research study examines the effects of introducing culturally relevant references into an Algebra unit for students of color, exploring the influence of exposure to cultural references and the minimal display of cultural and racial identities within the mathematics curriculum on students …

Examining Choices Of Sarcastic Responses In Dialogue With Virtual Interlocutors, Samantha Langley

Theses and Dissertations

We report the results from three experiments examining people’s preferences for using sarcasm in conversation as a function of: 1. whether their interlocutor uses sarcasm during the conversation; 2. Their knowledge about whether the interlocutor has used sarcasm in a previous conversation; 3. The presence of prosodical and visual cues for interlocutors’ sarcasm. In each experiment, participants took part in two conversations, and we manipulated whether the interlocutors were sincere or sarcastic and whether they remained the same or changed from one conversation to the next. Experiment one used written conversations and experiment two and three used pre-recorded video clips …

Four participants and one participant-observer engaged in a series of Professional …

The Processing Of Emotional Prosody And Semantics In Native And Non-Native Chinese Speakers, Cheng Xiao

Theses and Dissertations

Emotional information in spoken language is conveyed through both semantic and prosodic cues. While listeners interpret the meaning of utterances (what is said), they also detect the speaker’s emotional prosody (how it is said). For non-native speakers, processing these two types of information simultaneously can be challenging, particularly in a tonal language such as Mandarin Chinese, where the same acoustic feature (i.e., pitch) encodes both lexical semantics and emotional prosody. This dissertation reports a series of behavioral and fMRI experiments investigating how native and non-native Chinese speakers perceive and process emotional prosody and semantics in words and sentences. Behaviorally, results …

Anthropomorphism In Language And Thought: The Effect Of Agentive Linguistic Framing On Readers’ Perceptions Of Ai Animacy, Dawson Petersen

Theses and Dissertations

Over the past decade, deep learning AI systems have gone from academic obscurity to near cultural centrality in the developed world. As these technologies become increasingly integrated into daily life, there is growing cause for concern about AI anthropomorphism—i.e., the perception of AIs as more human than they really are. Despite the potential risks, AI developers continue to market their technologies using agentive language that seems to be designed to encourage anthropomorphism. The current dissertation utilizes behavioral and eye-tracking methods to examine the relationship between agentive linguistic framing and AI anthropomorphism in both controlled judgments and automatic inferences. The results …

Implicit Neural Representation For Image Reconstruction, Canyu Zhang

Theses and Dissertations

Image reconstruction seeks to restore corrupted images and recover visual content that has been lost or degraded. Such degradation may result from low resolution, occlusion, masking, or shadow interference. This problem has become an increasingly significant research topic, as visual information plays a central role in almost every aspect of modern life. Neural network based approaches have recently emerged as highly effective solutions for this task. In particular, convolutional neural networks and transformer based architectures have demonstrated remarkable success in producing visually convincing reconstructions. However, these models remain constrained in several important ways, one of the most critical being that …

Using a comparative case study of five teachers in Al-Ahsa, the study triangulates semi-structured interviews, classroom audio recordings, and teaching materials to compare stated beliefs with observable practice. The analysis is guided by the theories of English hegemony and language and gender ideology, which together illuminate how global linguistic hierarchies are localized through teachers’ beliefs and practices. Findings reveal that teachers occupy an ideologically complex position as they balance the national push for English proficiency under Vision …

Strategies For Developing Mathematical Identities In Middle School Students, Margaret M. Stevens

Theses and Dissertations

This concurrent mixed-methods action research study investigated the impact of mathematical discourse intervention on seventh-grade students’ mathematical identities and understanding. Twenty students participated in a four-week intervention implementing Smith and Stein’s (2018) five practices plus one framework.

Quantitative results showed curriculum-based assessments improved significantly (p < .001, d = 1.64). State mathematics assessment revealed minimal change in mean scores. The Mathematical Identity Questionnaire revealed positive shifts across all five constructs, with largest gains in Mathematical Initiative (+0.40) and Problem-Solving Persistence (+0.30). Qualitative analysis using Bingham’s (2023) five-phase process revealed three themes: Mathematical Voice Development, Identity Transformation Through Competence Building, and Communal Validation. Social Cognitive Theory and Culturally Relevant Pedagogy integration showed how discourse interventions addressed both individual self-efficacy and systemic inequities. Findings suggest intensive discourse intervention can initiate positive changes in mathematical identity and understanding for struggling students. Implications include restructuring mathematics instruction to prioritize student discourse and voice, creating more equitable learning environments.

Computational Analogies In The Era Of Large Language Models, Amarakoon Mudiyanselage Thilini Wijesiriwardene

Theses and Dissertations

Analogical reasoning is an important part of human cognition requiring the integration of abstract reasoning, pattern recognition, and background knowledge. Despite significant advances in language modeling, the capacity of current methods to accurately identify, model, and evaluate analogies remains fundamentally underexplored.

Analogies enable individuals to perceive deep similarities between superficially different situations. Effective analogy-making requires integrating knowledge about the external world with abstract reasoning and pattern recognition capabilities. While current language models (LMs), trained on massive textual corpora using autoregressive or masked objectives, achieve impressive performance across Natural Language Processing (NLP) tasks such as text generation, summarization, and classification, their …

Barriers such as academic preparedness, financial constraints, and sociocultural factors hinder their access to postsecondary education. However, by developing targeted strategies to assist ELs in accessing and completing college, institutions can address these challenges and ensure a more diverse and sustainable student body in the face of declining enrollment. Effective models for helping EL students access college include family engagement, early college exposure, peer mentorship, and student-centered advising. By assisting ELs in accessing college, institutions can strengthen their enrollment efforts, …

Unboxing The Black Box: Graph-Based Interpretability In Transformer Models, Ramak Nassiri

Theses and Dissertations

This thesis introduces a novel interpretability framework for transformer encoder models by hypothesizing that their internal embedding updates define a state transition system. We propose that transformers implicitly learn token-to-token influence dynamics, which can be analyzed using graph-theoretic methods. To validate this, we construct transition graphs from embedding changes and rank token importance using the PageRank algorithm. We develop two transformer models from scratch: a self-supervised model that incorporates serotype tokens to learn contextualized embeddings, and a supervised model initialized with these embeddings. Cosine similarity analysis of their token influence patterns reveals strong structural alignment, with values exceeding 93%. This …

Reflections Of Linguistic Experiences In A Borderland: Influences On Cultural Identity And Teacher Praxis, Iliana Cantu

Theses and Dissertations

This Autoethnographic dissertation uses autohistoria-teoria to critically analyze my lived curriculum as a Mexican-born raised in the borderland of the Rio Grande Valley. This research aims to understand the influence of my linguistic experiences on my cultural identity and teaching praxis within the same context. Drawing from Anzaldua’s (1987) concept of Borderlands as a contextual lens and Raciolinguistics as a theoretical framework, I examine and reflect on key linguistic experiences that have perpetuated colonizing linguistic practices rather than fostered linguistic diversity. Additionally, Culturally Linguistic Sustaining Pedagogy serves as a framework to critically analyze my teaching praxis in relation to my …

Barriers To Hispanic Post-Secondary Education In Science Fields, Luis Slayton

Theses and Dissertations

The study aimed to examine whether external barriers could be identified and are present throughout a Hispanic individual's educational life. The beliefs of the Hispanic community regarding education and the nature of acquiring an education could be relevant to the factors that impede the completion of high school. A survey approach was chosen as the methodology for the study due to the confidential nature of a questionnaire. Human nature tends to be more honest when not asked personal questions face-to-face. Additionally, there is potential to generalize attributes from a small sample to a larger population, allowing inferences about the identified …

Multi-Theoretic Perspective Of Backer Decision-Making In Crowdfunding: Interplay Of Backer, Founder And Ai, Maliha Alam

Theses and Dissertations

Crowdfunding has become a transformative mechanism for financing innovation, connecting creators directly with backers while bypassing traditional funding barriers. Despite its rapid global growth, only about 33.7% of campaigns succeed, largely due to ineffective communication of value propositions and lack of backer engagement. This dissertation investigates the complex interplay between project founders, backers, and emerging AI technologies to understand the factors influencing donation intention and to enhance crowdfunding success prediction.

Adopting the behavioral decision-making framework, I draw on multiple theoretical perspectives- signaling theory, the dual-process model of persuasion, and the cognitive-affective trust framework to examine founder- backer interactions. Using a …
