Storytelling, Gender, And The Double-Empathy Problem, Annie Rogers

Theses and Dissertations

Storytelling has been proposed as a meaningful way to facilitate empathy and connection, particularly across neurotypes. The present study examined whether a live storytelling event influenced perceptions of the autism community, empathy, and interpersonal connection, while also exploring differences on biological sex and levels of autistic traits. Participants completed pre- and post-event measures assessing relationship perceptions and connection, along with standardized measures of empathy and autistic traits. Results showed a significant increase in positive perceptions of the autism community and perceived closeness to storytellers after the event. Engagement, emotional impact, openness, and motivation to support the autism community were all …

The Evolution Of Collaborative Dialogue And Instructional Change Among Secondary Mathematics Teachers Engaged In Peer Observation, Shazia Akbar

Theses and Dissertations

This qualitative study examined how collaborative dialogue evolved across four cycles of a formative peer observation system involving one veteran and two first-year secondary mathematics teachers, exploring which aspects of that dialogue teachers attributed to changes in their instructional practice. Using the Math Talk for Equitable Participation (MTEP) framework across one academic year, data were drawn from verbatim transcripts of eight collaborative sessions and video-stimulated recall interviews. Four key findings emerged: evidence shifted from planning documents to video of student thinking, deepening pedagogical reasoning; novice teacher contributions grew from peripheral to central; relational trust fostered critical rather than merely affirming …

A survey instrument was created, which asked SLPs to respond to questions on various topics, including demographics, caseload information, assessment practices, statements on multilingual perceptions, and clinical scenarios. There were 267 participants included in the study from across the country with varying ages and years of experience in the …

Harnessing Story To Overcome The Double Empathy Problem Between Autistic And Neurotypical People: Brain-Behavior Relationships, Kate Gifford

Theses and Dissertations

There is a dearth of information on the physical aspects of the Double Empathy Problem which is the bidirectional challenge of shared empathy and understanding between autistic and neurotypical individuals. Storytelling has been shown as means to facilitate empathy between storytellers and listeners in both neurotypical and autistic populations through behavioral research. Functional near-infrared spectroscopy (fNIRS) is a neuroimaging technique used to evaluate the hemodynamic response in the cortex and can be used to compare hemodynamic responses across multiple individuals (i.e., hyperscanning). The purpose of this study was to examine activation in empathy-related brain regions and assess brain synchrony between …

Spatiospectral Lobes And Radiation Modeling Of Partially Coherent Supersonic Jet Noise, Tyce Wayne Olaveson

Theses and Dissertations

Noise fields generated by high-performance military jets are known to contain acoustic structures that differ from their simulated and lab-scale counterparts. These differences may limit current noise control efforts, which are designed and tested at scale before being considered for full-scale aircraft. One such noise structure is the presence of spatiospectral lobes, which appear as multiple spectral peaks at single microphone locations and multiple radiation lobes in field reconstructions. This dissertation uses data collected from the T-7A jet noise measurement to characterize the spatial behavior of the spatiospectral lobes as well as their first time-domain description. A multiple wavepacket decomposition …

Is Trimethylamine N-Oxide A Friend, Foe, Or Hormetic Agent In Patients With Parkinson’S Disease: A Focused Review Of One Microbial Metabolite, Abraham B. Alton

Student Works

This review synthesizes recent literature examining trimethylamine N-oxide (TMAO) synthesis and its potential role in Parkinson’s Disease (PD) pathology. An increase in TMAO plasma and CSF concentration is associated with PD progression and severity. TMAO biosynthesis is a two-step process. First, precursors including carnitine and choline are converted to trimethylamine (TMA) by gut microbes. Second, TMAO is oxidized to TMAO in the liver. Once absorbed into circulation TMAO crosses the blood brain barrier and may influence PD disease pathology by increasing neuroinflammation and astrocyte activation and damaging the cerebral lymphatic system. These mechanisms may contribute to the cognitive and motor …

This study examines the use of participatory art kits as a strategy for transforming family engagement within the art museum setting. Drawing on theories of experiential learning from John Dewey and participatory art practices rooted in the Fluxus art movement, my research positions art kits as tools that invite active, social, and embodied learning. Using a design-based research methodology, this study investigates how families interact with art kits within gallery spaces and how these tools influence and encourage conversation, artistic behaviors and relational dynamics. Data were collected through observation, family feedback and iterative kit redesign. Findings suggest that art kits …

Parent Perspectives On Primary And Secondary Online Learning, Barbara Tanner Sandberg

Theses and Dissertations

Given the growth of K-12 online learning and the expanded responsibilities parents often assume in this learning context, the purpose of this dissertation is to understand parents' perspectives on K-12 online learning. The first article reviews and synthesizes literature documenting parents' perspectives on how instructional modality affects parental support. Instructional modality affects parental support roles, parental perception of online school support, parents' lives outside the online course, and students' online learning support needs. Hence, parents expect modality decisions to account for modality affordances, student engagement, and personal circumstances. The second article examines parent perspectives on the decision to leave a …

The Relationship Between Musical Ability And Perceptual Skills For Speech Motor Learning In Young Adults, Emily Catmull

Theses and Dissertations

Speech motor learning is the multimodal process of acquiring speech sounds. Speech motor learning is trained through speech-language pathologist intervention in individuals across the lifespan. Previous research has explored which factors can influence speech motor learning, such as musical experience or training, which is the subject of this study. Sixty young adult participants (four male, 56 female) were recruited as part of a larger study that examined four possibly influential factors: bilingualism, phonetic knowledge, perceptual skills, and musical experience. Since the adult population has already acquired all the speech sounds in English, learning was measured using nonnative consonant clusters. Participants …

Same-Subject Induction Experiences For Elementary Music Teachers: Teacher Efficacy Beliefs, Experiences Of Isolation, And Job Satisfaction, Wendy Tams Hickman

Theses and Dissertations

This survey study seeks to explain the relationships between elementary music teachers' experiences with same-subject induction support and those teachers' feelings of teacher efficacy, experiences of isolation, and job satisfaction. Independent variables came from latent class groupings of same-subject induction support for beginning elementary music teachers. Teacher background variables were also included as controls. Three- and four-step regression models helped provide understanding about how the relative set of predictors--teacher background variables, isolation levels, induction experiences, and interaction terms--predicted the three outcomes. Initial regression analyses showed that the number of years of teaching elementary music predicted efficacy and levels of isolation …

The Correlation Between Perceptual Abilities And The Acquisition Of Non-Native Consonant Clusters, Hope Emma Nielson

Theses and Dissertations

A common approach in the study of speech motor learning is to have speakers learn to produce clusters of consonants that do not occur in their native language. This study investigated the relationship between auditory or speech perceptual abilities and the initial acquisition of non-native stop-stop consonant clusters. Sixty young adult participants (56 female, four male) were administered a gap detection test and a speech-in-noise test to assess their innate perceptual skills. The participants then performed a nonsense-word repetition task featuring non-native consonant clusters in the initial position. The participants' spoken productions of the nonwords were recorded and analyzed acoustically …

This paper starts with a review about Plant Functional Types and then goes deeper into the conceptual foundations of Plant Functional Types (PFT's) with detailed discussion of global trait spectra such as the leaf economics spectrum and the fast-slow continuum. Using concepts like response and effect traits, the review then talks about how a trait based ecological framework can provide a more robust guideline to classify plants. The review then talks about how players in basketball have been classified in the past along with some of the newer typologies. The review starts to draw some parallels between the ecological framework …

The Reliability Of Yolo Object Detection On The Amd Versal In A Proton Radiation Environment, Jacob D. Brown

Theses and Dissertations

Object detection is an important operation for satellites to be able to perform, and in outer-space missions it is crucial that machine learning models perform inference on satellite images accurately and reliably. Where size, weight, power, and other constraints exist, meeting this goal for accurate and reliable object detection is challenging. Additionally, soft errors caused by radiation further disrupt and degrade the operation of object detection in satellites. This thesis studies the performance of a deep learning model on an embedded device, the AMD Versal, in the presence of soft errors. The well-known and high-performing YOLO convolutional neural network was …

The Effects Of Phonetic Knowledge And Bilingualism On The Acquisition Of Non-Native Consonant Clusters, Kylie Wakley

Theses and Dissertations

Speech motor learning involves the production of new sounds or sound sequences. This study investigated how explicit phonetic knowledge and bilingualism affect how individuals acquire sound sequences that do not occur in English, or non-native consonant clusters. Sixty adults with typical speech, aged between 18 and 27 years, participated in the experiment. The researcher recruited participants into four groups based on their phonetic background (experienced or not) and language background (monolingual, bilingual). The participants produced stop-stop and fricative-nasal clusters in the initial position of nonsense words across six practice blocks. The duration of each cluster was measured, which in English …

In addition, the overarching goal of this research is to help speech-language pathologists (SLPs) better provide support and strategies to autistic individuals to improve their social and professional lives. Neurotypical English speakers (20 male and 20 female) were recruited to listen to a series of conversational speech samples collected from a group of eight autistic adults (four male and four female). In each sample, autistic individuals responded to a series of everyday …

Functional And Structural Lesion Network Mapping: Insights Into Acquired Brain Injury And Insomnia, Kathleen Erekson Rugh

Theses and Dissertations

Insomnia disorder is the most reported sleep disorder and can negatively affect daily functioning. Acquired brain injuries can lead to insomnia disorder. Limited research has explored a causal link between brain networks and insomnia symptoms in this population. This study replicated a lesion network mapping methodology of an insomnia study (Helquist et al., 2024) and extended it to examine structural networks linked to insomnia symptoms in individuals with acquired brain injuries. Traced lesions (N =44) were used as seed regions to compare against normative functional and structural network data. For functional analyses, we used resting state fMRI scans from a …

Baseline Moderators Of A Transdiagnostic Adolescent Sleep And Circadian Health Intervention's Effectiveness At Improving Circadian Sleep Health: A Pilot Investigation, Jamon M. Jex

Theses and Dissertations

The current study examined whether baseline demographic and clinical characteristics moderate the effectiveness of the Transdiagnostic Sleep and Circadian (TSC) intervention in improving adolescent circadian sleep health. Using an integrative data analysis approach, data from three independent adolescent samples (N = 134; ages 10-18) were pooled to evaluate changes across multidimensional sleep outcomes defined by the RU-SATED model of sleep, including regularity, satisfaction, alertness, timing, efficiency, and duration. Linear mixed-effects models were used to assess pre-to-post intervention changes and test moderation by age, sex, family income, and clinical status. Results indicated significant improvements in sleep satisfaction following TSC, with greater …

Real-Time Instruction Internalization For Large Language Models, Brenden Smith

Theses and Dissertations

For the end user, Large Language Models (LLMs) are programs that process natural language inputs into natural language outputs. In popular usage, this tends to take the form of conversation: a user asks a question, provides information, or gives instructions, and the LLM (hopefully) replies in a manner we would expect of an informed and compliant person. While convenient and intuitive for users, this natural conversational format encourages the misconception that LLMs are learning from conversations, when they do not. This work presents the benefits and practicality of a language model paradigm that meets this user expectation -- that is, …

Neuroscience-Based Intellectual Productivity: A Ten-Principle Methodology For Knowledge Workers, Yoshihiko Ariizumi

Learning, Teaching, & Researching Optimization

This paper presents a comprehensive, neuroscience-grounded methodology for enhancing intellectual productivity among knowledge workers—particularly academic faculty and researchers operating under conditions of chronic cognitive overload. Drawing on ten foundational principles derived from contemporary cognitive neuroscience, we argue that substantial gains in research output, creative ideation, and knowledge integration are achievable not by working harder, but by working in deliberate alignment with the brain’s native computational architecture.

The ten principles address: strategic activation of the Default Mode Network (DMN) for incubation and creative insight; prefrontal cortex (PFC) energy management through temporal task separation; externalization of cognitive load via AI-assisted working memory …

Pioneering Change: Digital Reformatting For Sustainable Av Stewardship, Cory Nimer, Ben Harry, Abby Beazer, Miya Jensen, Michael Gates, Karen Glenn

Faculty Publications

Archives and libraries face growing preservation challenges from aging audiovisual collections due to carrier degradation and playback equipment obsolescence. As the media becomes more difficult to access, its archival value decreases, leading to questions about its ongoing storage. One proposed solution has been to digitize and discard the original media, preserving the recordings as digital masters with derivative files for public access. The suggestion to reformat audiovisual materials raises questions for cultural heritage professionals, and each stakeholder group may have its own concerns. Yet as media capture and digital preservation technology improve, to maintain our program's sustainability, we have begun …

Engagement Modeling And Inference For Risk-Aware Path Planning Under Adversarial Uncertainty, Grant Stagg

Theses and Dissertations

This dissertation develops methods for planning safe and efficient trajectories for autonomous vehicles operating in environments containing adversarial and environmental threats with uncertain parameters. The central objective is to quantify and control the risk of adverse events--such as interception or detection--when threat characteristics are imperfectly known. To address this challenge, probabilistic weapon engagement zone (PEZ) models are introduced to estimate the likelihood of violating adversarial engagement constraints under uncertainty in pursuer state and capabilities. Multiple computational strategies are developed for PEZ evaluation, including first-order sensitivity-based approximations, Monte Carlo estimation, and neural-network surrogate models. These approaches enable rapid engagement-probability assessment and …

Analysis Of Approximations In Flash Thermal Diffusivity Measurements Using High‑Fidelity Simulations, Tage T. Burnett, Jakob G. Bates, Matthew R. Jones, Christopher R. Dillon, John Tencer

Faculty Publications

Thermal diffusivity is an important material property for understanding and characterizing transient behavior in many heat transfer applications. This study investigates the accuracy and approximations of inverse mathematical models for measuring thermal diffusivity of materials via the widely used Flash Method. High-fidelity simulations of the Flash Method in copper, silicon carbide, silicon, and glass were performed as numerical experiments and included physics such as in-depth absorption, radial conduction, and surface convection. Data from those numerical experiments were used to estimate material thermal diffusivity using seven traditional and new inverse models. Parker’s original model had relative errors 𝜖< 5% when the approximations it makes were enforced in numerical experiments. Newer models performed well even when experimental restrictions were relaxed. Models that include radial heat conduction were capable of accurately measuring thermal diffusivity (𝜖< 1%) when a Gaussian energy source was used. Models with radial conduction and in-depth material absorption of the laser source could calculate thermal diffusivity for semi-transparent materials such as silicon (𝜖< 1%) and even transparent materials like glass (𝜖< 10%). Convective losses from the material’s front surface had a negligible impact on measurements except for very low thermal diffusivity materials. Using temperatures from many locations of the test material’s surface increased resilience to noise, reducing the distribution of thermal diffusivity measurements by more than an order of magnitude. The models developed in this study could enable a more relaxed Flash Method experimental setup that maintains thermal diffusivity accuracy and extend the utility of the Flash Method to semitransparent materials.
