Health Services and Informatics Research
Possible effects of parent phone use on parent–child interactions and child behavior are of concern, warranting research to understand parent phone use. In this survey study of 183 families with a young child (M = 2.89 years), we examined parents’ phone use for texting/calling, social media (SM) use, mobile gaming (MG), and perceptions of cutting into family time; we also examined differences between mothers and fathers and associations with parenting stress. Mothers engaged in greater SM use but less MG compared to fathers; 61% of mothers and 38% of fathers used SM 31+ min per day, while 23% of …
The Anatomy Of A Reconstruction: From Fourier Space To Image Recovery In Computed Tomography, Charlotte P. Maurer
The Anatomy Of A Reconstruction: From Fourier Space To Image Recovery In Computed Tomography, Charlotte P. Maurer
Honors Theses
This thesis develops the mathematical foundations of computed tomography (CT) reconstruction through the lens of harmonic analysis. Beginning with the Schwartz class, we introduce the Fourier transform and its role in expressing the Radon transform and its inversion via a fractional Laplacian. After constructing the Radon transform in general dimension R^d, we specialize to the cases d = 2 and d = 3, demonstrating explicit inversion formulas and the associated instability in lower dimensions. For its computational advantages, we study filtered back-projection using classical low-pass filters (Ram-Lak, Shepp–Logan, Cosine, Gaussian) and formulate a discrete reconstruction algorithm grounded in …
How Does Cocaine Exposure Affect Early Gene Expression Changes In The Prefrontal Cortex (Pfc) And Striatum?, Saathvika Diviti
How Does Cocaine Exposure Affect Early Gene Expression Changes In The Prefrontal Cortex (Pfc) And Striatum?, Saathvika Diviti
Honors Theses
Cocaine use disorder (CUD) remains a significant public health concern, yet the molecular mechanisms underlying individual susceptibility are poorly understood. This study investigates early transcriptional responses to acute cocaine exposure in two key brain regions implicated in addiction, the prefrontal cortex (PFC) and striatum, using genetically diverse Diversity Outbred (DO) mice. Paired tissue samples were collected following a standardized sensitization protocol and analyzed via bulk RNA sequencing. Differential expression analysis revealed 37 significantly differentially expressed genes in the striatum. These genes overlapped with gene sets associated with substance use, neurodevelopmental disorders, and immune signaling, implicating shared pathways in central nervous …

OTD 721: Cultural Responsiveness & Occupation
I went in to OT to make the world more accessible. I love how OT views people as their hopes, dreams, values, strengths, and facilitators...NOT as an injury or disease. At this point, every room I enter becomes a personal case study of accessibility. I can't help but wonder how many spaces have hung huge signs that say "YOU ARE NOT WELCOME" that are only visible to some. I'm thankful for my love ones who agreed to help me with this project. While I can never fully understand their experience, I can listen.

Summer School: The Experience Of An Occupational Therapy Student Exploring Culture In Spokane!, Lulu Brady
OTD 721: Cultural Responsiveness & Occupation
This zine illustrates my experience in this OTD 721 Cultural Responsiveness class, led by Dr. Kirkpatrick. The class took place in the summer of 2025. It was absolutely inspiring, and I wanted to be able to share my takeaways and learnings from my experiences in this class. Culture is so relevant to the field of occupational therapy (OT) because occupations are often shaped by culture, OT cannot be truly client-centered without respective culture. Not only did this class help me grow as a future occupational therapist practitioner, but it also helped me grow as a person. It showed me the …

Welcomed In: A Love Letter To Okinawa, Taylor Fernandez
OTD 721: Cultural Responsiveness & Occupation
This zine is a personal, reflective project exploring Okinawan culture through my lens as a long-term guest -- first as a military child, then as an adult returning "home" to visit the island where my parents still live. While I am not Okinawan, the culture has deeply influenced my values, worldview, and understanding of community, aging, and wellness.
Through this project, I have sought to honor the richness of Okinawan traditions -- not as an authority, but a someone shaped by the grace of being welcomed in. The pages blend scholarly knowledge, lived experience, and cultural observation to explore how …

Occupational Apartheid, Kimberly Dewey
OTD 721: Cultural Responsiveness & Occupation
Occupational apartheid is a term that is often misunderstood. I wanted to bring more awareness and understanding to a very real concept that happens every day. I hope to have provided education and examples that make it easy to follow along and see how apartheid shows up on a daily basis. Let's work together as future OT professionals to expand our knowledge and practice to decrease experiences of occupational apartheid.

Autism Spectrum Disorder (ASD) is a developmental disability accompanied by a wide range of neurodevelopmental disorders. ASD can affect anyone regardless of race, socioeconomic status, or ethnicity (CDC, 2025). Individuals with ASD tend to have issues with various challenges and strengths regarding how they learn, think, and solve problems. Some children with ASD have repetitive patterns of behavior, restricted interest in activities, and difficulty in communication and social interaction.
According to the World Health Organization, the global prevalence of ASD 1 in 100 children diagnosed with Autism. Additional data supplied by the CDC states that the number of children with …
Mental Health Trends Among African American High School Students, Alexis Heard
Mental Health Trends Among African American High School Students, Alexis Heard
Theses and Dissertations
Adolescent mental health is a major public health issue in the U.S., with African American high school students facing a rapidly worsening crisis. While all youth show increasing rates of depression, anxiety, and suicidality, African American adolescents are at greater risk due to systemic racism, socioeconomic inequality, community violence, and limited access to culturally responsive care. Few national studies have examined mental health trends among this group. This study (1) examines 2011–2021 trends in persistent sadness/hopelessness, suicidal ideation, suicide planning, and suicide attempts among African American high school students; (2) explores gender differences; and (3) compares these patterns to national …

Introduction: Systemic sclerosis is a rare autoimmune disorder defined by skin thickening in the distal digits and is frequently accompanied by inflammatory arthritis. There are known mimics of systemic sclerosis, which present with similar sclerosis of the skin. Palmar fasciitis and polyarthritis syndrome (PFPAS) is a rare paraneoplastic syndrome that presents with progressive flexion contractures of the hands, inflammatory fasciitis, fibrosis, and generalized inflammatory arthritis. PFPAS is most associated with ovarian adenocarcinoma, and rarely associated with pancreatic adenocarcinoma. Early recognition of this rare syndrome was critical in identifying an asymptomatic pancreatic adenocarcinoma. Case Description: 58-year-old woman with osteoarthritis of multiple …
Implementing Holograms To Perform Cognitive Health History Screenings, Franchesca I. Gonzalez
Implementing Holograms To Perform Cognitive Health History Screenings, Franchesca I. Gonzalez
Honors Undergraduate Theses
Marginalized populations, defined as a group of individuals who experience systematic disadvantages due to various social identity factors (Oxford Review, n.d.), experience uneven barriers to cognitive and mental health assessments, including socioeconomic, linguistic, and educational inequities, that contribute to misdiagnosis (Petersen et al., 2018, Saeed & Masters, 2021). This study investigates the feasibility of hologram-based patient simulations as an educational intervention for undergraduate nursing and graduate Nurse Practitioner students. Culturally representative, three-dimensional holographic patients were created to replicate complex geriatric encounters and facilitate cognitive health screenings. Established assessment tools, including the Mini-Mental Status Examination, Patient Health Questionnaire 2 and Patient …

Studies that were only partially available were also not used. The databases used were PubMed, …
Ultra-Plex Immunofluorescence Stainings To Classify Precancerous Lesions For The Stratification Of Their Risk For Progression Toward Esophageal Squamous Cell Carcinoma, Arthi Jaishankar
Honors Undergraduate Theses
Esophageal squamous cell carcinoma (ESCC) is the most common and fatal type of esophageal cancer since it is usually only diagnosed at a later stage. Similar to other cancers, ESCC arises through precursor lesions which are known as dysplasias and occurs when cells have uncontrolled growth and changes to both the tissue structure and gene expression. Clinical intervention at the precancerous stage would greatly improve survival rates, however predicting which lesions will actually become malignant continues to be a challenge. The current traditional method for ESCC diagnosis is hematoxylin and eosin (H&E) histopathology, but it is not sufficient for predicting …
Effect Of Sapropterin Dihydrochloride On Neuropsychiatric Functions For Individuals With Phenylketonuria: A Systematic Review, Ricky Lin
Honors Undergraduate Theses
Phenylketonuria (PKU) is a rare metabolic disorder that occurs in approximately 1 in 10,000 births worldwide. Individuals with PKU cannot properly metabolize phenylalanine (Phe) due to a deficiency in phenylalanine hydroxylase (PAH), leading to elevated Phe levels and associated cognitive and neuropsychiatric impairments. Although early dietary management has reduced the risk of severe intellectual disability, many individuals with PKU continue to experience deficits in attention, executive functions, and mood regulation. Sapropterin dihydrochloride, a synthetic form of the PAH cofactor tetrahydrobiopterin (BH4), offers a pharmacological alternative that enhances residual enzyme activity in responsive individuals. While its efficacy in lowering blood Phe …
Lifetime History Of Concussions In Relation To Blind Perceptual Distance Estimation Ability, Mackenzie K. Miller
Lifetime History Of Concussions In Relation To Blind Perceptual Distance Estimation Ability, Mackenzie K. Miller
Honors Undergraduate Theses
This study examined the relationship between visuospatial estimation and a lifetime history of concussions. Current literature on concussions investigates visuospatial working memory and estimation ability separately, but not conjointly. In order to examine this relationship, a novel neuropsychological task was designed to measure visuospatial estimation ability in working memory, named the Perceptual Estimation Test (PET). This novel task was designed with three variations that would increase in complexity as they progressed, and each variation would include three trials. Participants were scored on their accuracy performance during the PET. Participants aged 18-25 were recruited from students attending the University of Central …

The Effect Of Temperature And Salinity On Margalefidinium Polykrikoides Group Iii Va, Usa Strain Growth, Eduardo Pérez-Vega, Margaret R. Mulholland, Katherine E. Crider, Kimberly E. Powell, P. Dreux Chappell, Alexander Bochdansky
OES Faculty Publications
Margalefidinium polykrikoides is a cosmopolitan dinoflagellate that blooms in coastal waters. Despite genomic evidence that it belongs to Group III and so closely related to isolates from Puerto Rico, Malaysia, North America, and Central America, M. polykrikoides blooms in the Chesapeake Bay at warmer temperatures and lower salinities than in coastal ecosystems occupied by its closest relatives. In this study, the effect of temperature and salinity on the growth rate and total cell yield of an M. polykrikoides VA culture isolate were examined and compared with environmental observations made during M. polykrikoides blooms in the Chesapeake Bay. M. polykrikoides group …
Revealing Spatiotemporal Neural Activation Patterns In Electrocorticography Recordings Of Human Speech Production By Mutual Information, Julio Kovacs, Dean Krusienski, Minu Maninder, Willy Wriggers
Revealing Spatiotemporal Neural Activation Patterns In Electrocorticography Recordings Of Human Speech Production By Mutual Information, Julio Kovacs, Dean Krusienski, Minu Maninder, Willy Wriggers
Mechanical & Aerospace Engineering Faculty Publications
Background
Spatiotemporal mapping of neural activity during continuous speech production has been traditionally approached using correlation coefficient (CC) analysis between cortical signals and speech recordings. A prior study employed this approach using electrocorticography (ECoG) data from participants who underwent invasive intracranial monitoring for epilepsy. However, CC cannot detect nonlinear relationships and is dominated by the correspondence between periods of silence and of non-silence.
New Method
We introduce the mutual information (MI) measure, which can capture both linear and nonlinear dependencies. We validated CC and MI on the sub-second spatiotemporal brain activity recorded during continuous speech tasks. To refine the results, …

Traction Force Microscopy Using An Epifluorescence Microscope: Experimental Considerations And Caveats, Zaria Booth, Mazen Mezher, Rudra Patel, Venkat Maruthamuthu
Mechanical & Aerospace Engineering Faculty Publications
Forces exerted by cells due to their internal contractility play fundamental roles in a host of processes, including adhesion, migration, survival and differentiation. Traction force microscopy (TFM) enables the determination of forces exerted by cells or cell collectives on their environment, which is typically taken to be an extra-cellular matrix (ECM)-coated substrate. Sample preparation for TFM involves the plating of cells onto an environment embedded with fiducial markers. The imaging of these fiducial markers in the presence and absence of the cells then enables calculation of the displacement of localized regions of the environment, and, consequently, the spatial distribution of …
An Analytical Model Of Motion Artifacts In A Measured Arterial Pulse Signal—Part Ii: Tactile Sensors, Md Mahfuzur Rahman, Subodh Toraskar, Mamun Hasan, Zhili Hao
An Analytical Model Of Motion Artifacts In A Measured Arterial Pulse Signal—Part Ii: Tactile Sensors, Md Mahfuzur Rahman, Subodh Toraskar, Mamun Hasan, Zhili Hao
Mechanical & Aerospace Engineering Faculty Publications
This paper, the second of two parts, presents an analytical model of motion artifacts (MA) in measured pulse signals by a tactile sensor, which contains a deformable microstructure sitting on a substrate. While the tissue-contact-sensor (TCS) stack and the sensor are both treated as a 1DOF (degree-of-freedom) system, tissue–sensor contact joins their mass together to form a 1DOF system with springs and dampers on both sides. MA on the sensor substrate causes baseline drift and time-varying system parameters (TVSP) of the TCS stack simultaneously. An analytical model is developed to mathematically relate baseline drift and TVSP to a measured pulse …
