Childhood Through Motion: Reimagining Everyday Mobility Corridors For Learning, Independence, And Exploration, Olivia Liljegren

City and Regional Planning

This project proposes the Childhood Through Motion (CTM) Framework, which reimagines how everyday mobility corridors can support children’s development through repeated engagement with integrated interventions along key neighborhood routes. Building on existing approaches such as Safe Routes to School and Playful Learning Landscapes, the framework integrates mobility, play, learning, and social interaction into a connected system of corridors and nodes distributed throughout a neighborhood street network. Rather than treating mobility, play, and learning as separate, the framework explores how developmental opportunities can be integrated into the public spaces children use every day.

The framework is organized through five guiding principles …

Walking The Walk: Centering Praxis In Teaching Abolition, Mei-Ling N. Malone

Feminist Pedagogy

Teaching abolition in the university setting from a theoretical standpoint often leaves students feeling disconnected from its real-world implications and does not connect or empower students to join this work. Bettina Love argues that “too often we think the work of fighting oppression is just intellectual. The real work is personal, emotional, spiritual, and communal.” As an assistant professor of African American Studies and an abolitionist feminist, who centers praxis in my pedagogy, my involvement in abolition organizing on campus is the real work that Love asks of educators. I organize with a small group of students and professors to …

Story Exchange Walls: Bridging Community And Carceral Spaces Through Writing, Tobi Jacobi, Braden Bomgaars

Feminist Pedagogy

The “story exchange wall” activity that follows expands the scope and accessibility of stories that can contribute to building infrastructures grounded in abolition-minded practices of care and relationality. Story exchange walls are built upon the premise that: a) not all community voices are heard; b) there is value in pursuing understanding across discourse communities; and c) writing is an engaging method for encouraging dialogue on social issues and dismantling misconceptions about system-impacted people and their community commitments and contributions. Through a series of written and displayed dialogues, mobile story exchange walls offer a dynamic tool for engaging social issues and …

Creating Abolitionist Classroom Environments And Three Abolitionist Learning Activities, Marina Bell

Feminist Pedagogy

In this paper I describe some of the approaches I have developed over the past six years of abolitionist teaching in the classroom. I will focus on three activities for helping students grapple with abolitionist concepts, principles, and values experientially, with the goal of generating conversation about some of their most challenging aspects, and working through emotions around them. Specifically these exercises are: 1) Distinguishing between carceral and abolitionist reforms, 2) What do we do with “the dangerous people” and our feelings about them?, and 3) A mutual aid exercise in which I have students identify and choose together what …

Fully Integrated Slippage Detection System For Lower Limb Amputees, Christopher E. Miglio

Master's Theses

Lower limb amputees face significant challenges in maintaining a proper prosthetic fit, as improper fit can lead to slippage at the limb-socket interface, resulting in discomfort, pressure sores, and long-term musculoskeletal complications. To address this issue, a fully integrated slippage detection system was developed to monitor an amputee’s daily activities and slippage occurrences to understand their prosthetic fit over time. The system consists of a prosthetic sock embedded with Interlink 406 flexible piezoresistive force-sensing resistors (FSRs). The sock, worn directly on the residual limb, continuously measures pressure at the limb-socket interface. Sensor data from six FSRs is sampled at approximately …

An Analysis Of Neuroidal Memory Formation Within D. Melanogaster, Jerry Chang

Master's Theses

The Neuroidal model poses a neurobiologically plausible theory for modeling the brain. This symbolic network has been shown to capture realistic memorization behaviors using the JOIN algorithm. The model has also been recently improved by incorporating Watts-Strogatz small-worlds within its base structure. From the efforts of neuroscience researchers, we have access to the Drosophila melanogaster (D. melanogaster) fruit fly’s connectome, which has been found to also contain small-worlds in this thesis. By synthesizing the Ocellar Ganglion (OCG) region of Drosophila, we compare a digitized version of a real-world brain with an instance of the Neuroidal model. In this thesis, we …

Using Scenario-Based Design Activities To Explore Sociotechnical Thinking In Engineering Professionals, James M. Whealan

Master's Theses

Sociotechnical thinking is the ability to recognize the interconnectedness of both technical and non-technical dimensions such as environmental, economic, social, cultural, and political factors. Although traditional engineering curriculum often emphasizes technical knowledge and skills, research suggests that engineering work is inherently sociotechnical. While sociotechnical thinking is a critical engineering skill, relatively little is understood about the nature of it or the different aspects comprised within it. To that end, this study addresses the following research question: What sociotechnical factors do engineering professionals consider in a collaborative scenario-based design activity? To answer this question, we conducted a qualitative study of engineering …

Psychological Effects Of Health Disparities: A Multi-Identity Understanding, Shayda Shokooh, Kiana Hosseinzadeh, Olivia Copeland, Katie Wong

Psychology and Child Development

The United States has a long history of public health inequities which continue to impact individuals based on their varying intersectional identities. These systemic obstacles often impede access to healthcare, comprehensive treatment by physicians, and preventative care, among other factors. Disparities within healthcare consequently result in decreased overall well-being and negative psychological impacts, based on identity. We reviewed a variety of academic peer-reviewed studies, both empirical and systematic, investigating three identity factors: racial and ethnic minorities, socioeconomic status, and cognitive disabilities, and examining how these facets influence a person’s mental state and experience of healthcare. We analyzed each of these …

Accelerating Relationship Discovery In Chronic Lower Back Pain Through Knowledge Graph And Ontology Enhanced Large Language Models, Damon Lin

Master's Theses

Chronic lower back pain (cLBP) is a widespread public health burden linked to anxiety, depression, and opioid addiction. Interventions aimed at treating cLBP have shown minimal improvements in pain outcomes, leading researchers to reexamine our understanding of cLBP through constructing a causal model. However, constructing causal models through Randomized Controlled Trials are often unfeasible, and relying on domain expertise requires extensive and time-consuming research, posing a serious bottleneck for designing effective treatments. To accelerate this process, we apply Knowledge Graphs, Ontologies, and Large Language Models (LLMs) to aid researchers in determining possible causal relationships. First, we demonstrate how LLMs can …

Generalized Detection Of Animal Behavior Using Accelerometers, Alexander J. Arrieta

Master's Theses

Animal mounted sensors are becoming increasingly used to passively monitor both domestic and wild animals. Advances in lightweight accelerometer and GPS technology have allowed many animals to be fitted with high accuracy sensors for extended periods of time. This leads to new opportunities to study animal behavior without direct observation. However, interpreting the raw data is difficult due to the high volume and missing context of the information. Machine learning techniques excel at extracting information from raw data streams and are excellent candidates for processing the sensor data. However, due to large variance in how different animals execute the same …

Per- And Poly-Fluoroalkyl Substances Fate Across California Wastewater Treatment Plants: A Meta-Analysis Of Formation, Distribution, And Persistence, Elizabeth Reineke

Master's Theses

Per- and poly-fluoroalkyl substances (PFAS) are persistent contaminants that move through municipal and industrial wastewater systems with limited attenuation. As a result, they are increasingly detected in drinking water supplies. Despite growing regulatory concern, a systems-level understanding of PFAS behavior across multiple treatment facilities and watershed settings remains incomplete. This study compiled influent, effluent, and biosolids datasets from more than one hundred California wastewater treatment plants to evaluate PFAS occurrence, transformation, and partitioning across diverse treatment configurations. Analytical steps included calculating removal efficiencies, assessing precursor-to-product oxidation, evaluating co-contaminant correlations, and grouping facilities by process design to quantify configuration-specific fate patterns. …
