Play-Based Assessment Of The Cardinal Principle, Allyssa Sonnefeld Leavitt

Theses and Dissertations

Gelman and Gallistel (1986) determined five counting principles that are essential for successful counting, including the cardinal principle where children understand that the last number counted represents the quantity of a set of objects. The traditional How many? task and the Give-n task are the most common tasks that have been used to assess whether children understand the cardinal principle. However, many researchers claim that these tasks either overestimate or underestimate children's understanding of the cardinal principle. Some researchers (Baroody & Pellegrino, 2023) suggest that embedding the traditional How many? task in a game may improve its validity. In this …

The Negotiation Of Identities Through Humorous Discourse In Political Resistance: An Analysis Of Bassem Youssef's 'The B+ Show', Howaida Aref

Theses and Dissertations

This study examines the strategic use of humorous discourse in negotiating identities and expressing political resistance during the 2011 Egyptian Revolution, focusing on Bassem Youssef's satirical YouTube show, "The B+ Show." Employing a mixed-method approach that combines Grice's maxims of cooperative communication and Fairclough's critical discourse analysis framework, the research investigates how humor functioned as a tool for challenging hegemonic narratives and power dynamics through constructing and deconstructing identities in a volatile sociopolitical context. The analysis reveals that Youssef skillfully exploited various discursive resources, particularly intertextuality and the flouting of conversational maxims, to generate implicatures that effectively debunked negative representations …

Approximately 1 in 5 adolescents are diagnosed with a mental, emotional, or behavioral condition (Panchal, 2024; Sappenfield et al., 2024). Yet, an estimated 40% (1.8 million) of adolescents aged 12-17 who experience a major depressive episode did not receive treatment (Substance Abuse and Mental Health Service Administration, 2024). This project examines existing barriers that hinder access to care for this population. While schools are the most common settings for adolescent mental health supports, more than half report difficulties with meeting …

The Social In The Spiritual: Non-Theistic Spirituality In 12-Step Addiction Recovery, Steph Jacobs

Theses and Dissertations

To investigate whether Western-raised Narcotics Anonymous (NA) members engage in non-theistic spirituality and non-humanist modes of sociality with non-human beings, I conducted six qualitative interviews and a small-scale survey within a Vancouver NA community. The majority of participants practice non-theist spirituality, and three interviewees relate to non-humans in ways not accounted for by Western humanism. Findings suggest that connection and sociality are intrinsically woven into recovery and well-being. This research opens conversations about non-theistic spirituality in NA recovery, non-human sociality and healing, processes of ontological negotiation, and the entanglement of spirituality, sociality, and well-being. Through daily practices of exploration and …

Toward An Anthropological Ecocriticism, Grant Mcmillan

Theses and Dissertations

Environmental storytelling has increasingly reckoned with concepts and assumptions about (N/a)ture inherited from the Western intellectual tradition. The late 2010s and early 2020s in particular have seen an explosion of fiction that interrogates the limits of these past ideas. Relatedly, ecocriticism of this period has entered a self-reflexive mode that has sought to deal with its own limitations while offering insights that may prove generative for a more general audience of environmentally minded readers. This project adds to ongoing ecocritical discourse by tracing a series of implicit affinities between the broad traditions of anthropology and environmental fiction through their shared …

Looking At Teacher Knowledge, Skills, And Dispositions To Create School-Wide English Learning, Grace Elizabeth Allely

Theses and Dissertations

This dissertation-in-practice addresses the gap between teacher preparation and the rapidly growing multilingual learner population in U.S. public schools, where one in four students is classified as an English Learner yet only half of states mandate specialized teacher training for this population. Grounded in sociocultural learning theory, the know-do gap framework, and implementation science principles, this qualitative study investigates how the School-Wide English Learning (SWEL) peer coaching model bridges the divide between educators' theoretical knowledge and classroom application. Through focus group interviews with eleven general education teachers who participated in SWEL coaching for at least six months in Minnesota District …

Burdened By Conviction: The Pressures Within, Dulce M. Perez

Theses and Dissertations

This thesis investigates how religious and political systems, particularly Catholic influences in the Rio Grande Valley, limit and silence women. By employing historical and alternative photographic techniques such as cyanotype, gum bichromate, and photo transfer, I express how these systems control and shape women’s lives. Combined, the materials serve as a metaphor for the oppression and damage which power can inflict. In these works, fabric represents the potential for manipulation of the human mind; the red thread stitched through cloth and paper symbolizes control; and fragmented images are a reference to the collapse of humanity. Throughout this exploration, I reflect …

It is grounded in the theoretical framework of Nepantla, a concept introduced by Gloria Anzaldúa to describe the unseen space of the border life as one of existing between worlds, identities, and cultures. Included and essential to this work is the Coyolxauhqui Imperative, which informs the process of …

Efficient Self-Supervised Representation Learning For Large-Scale Time Series Classification, Kevin Garcia

Theses and Dissertations

Recently, there has been a significant advancement in designing Self-Supervised Learning (SSL) frameworks for time series data to reduce the dependency on data labels. Among these works, hierarchical contrastive learning-based SSL frameworks, which learn representations by contrasting data embeddings at multiple resolutions, have gained considerable attention. Due to their ability to gather more information, they exhibit better generalization in various downstream tasks. However, when the time series data length is significant long, the computational cost is often significantly higher than that of other SSL frameworks. In this paper, to address this challenge, we propose an efficient way to train hierarchical …

Interpretable Alignment Of Textual Weather Reports With Local Sensor Time Series For Extreme Weather Event Visualization, Juan Luis Garza

Theses and Dissertations

This thesis presents an automated and interpretable pipeline that links natural-language weather narratives with local meteorological sensor time series. Using large language models, NOAA-style event reports are transformed into structured records capturing event type, timing, descriptive context, and uncertainty. Each extracted event is aligned with harmonized temperature, precipitation, and wind measurements from nearby weather stations, enabling systematic comparisons between narrative evidence and observed atmospheric conditions.

Across roughly fifty stations and more than two thousand events, the analyses show that discrepancies between narrative descriptions and sensor behavior arise primarily from spatial separation rather than from temporal offsets, sensor preprocessing artifacts, or …

When Scripts Diverge: Strengthening Low-Resource Neural Machine Translation Through Phonetic Cross-Lingual Transfer, Ammon Shurtz

Theses and Dissertations

Multilingual Neural Machine Translation (MNMT) models enhance translation quality for low-resource languages by exploiting cross-lingual similarities during training--a process known as knowledge transfer. This transfer is particularly effective between languages that share lexical or structural features, often enabled by a common orthography. However, languages with strong phonetic and lexical similarities but distinct writing systems experience limited benefits, as the absence of a shared orthography hinders knowledge transfer. To address this limitation, we propose an approach based on phonetic information that enhances token-level alignment across scripts by leveraging transliterations. We systematically evaluate several phonetic transcription techniques and strategies for incorporating phonetic …

An Analysis Of Large Language Model Hallucination And Creativity: Linear Representations And Causal Roles, Mckay Bowcut

Theses and Dissertations

Large language models (LLMs) show remarkable abilities in both factual and creative tasks, yet the problem of hallucination persists despite advances in training and post-training methods. Recent progress in model interpretability suggests that model behavior can be predicted and influenced by analyzing and manipulating internal activations. In this thesis, we address three questions: (1) Can we identify linear representations of hallucination and creativity in the model’s latent space? (2) Do these representations play a causal role in model behavior when manipulated? (3) Are creativity and hallucination causally intertwined? To answer these, we construct a novel dataset of factual, hallucinated, and …

Cultural Diagnosis And The Monsters Of Victorian England, Victoria Elizabeth Kuykendall

Theses and Dissertations

This dissertation examines the representation of invisible disability and neurodivergence in nineteenth-century British literature, arguing that literary texts both reflect and shape cultural understandings of disability. While much scholarship has focused on visible or physical impairments in Victorian fiction, comparatively little attention has been given to characters whose behaviors, emotions, or identities align with what today might be described as neurodivergence.

Drawing on Disability Studies, Mad Studies, and cultural theory, I propose the concept of cultural Diagnosis as a framework for analyzing how fictional characters become “Diagnosable” within both their historical and contemporary cultural contexts. Through close readings of Arthur …

The speech task involved the repetition of sentences that included specific vowel targets, and the non-speech task was a visuomotor pursuit rotor task which required tracking a moving target on a computer. The participants were twenty young adults between the ages of 18 and 30 and twenty older adults above the age of 60. They performed each task on its own and both tasks concurrently, prioritizing one or the other task. Audio recordings were analyzed with software to extract …

Speech Motor Learning In Divided And Undivided Attention Conditions, Garrett Barnes

Theses and Dissertations

This study investigated the effect of dual tasking on speech motor learning. Forty young adult participants (20 male, 20 female) practiced speaking nonsense words containing non-English consonant clusters. Half of the participants practiced the words while also completing a shape identification task. After practice, the two groups produced the words in a retention task both with and without the shape identification task. They returned the next day to produce the words again with and without the shape identification task. Acoustic analysis of the consonant cluster and word duration was used as an index of motor learning. Statistical analysis revealed that …
