"I Know Who I Am": Draw-And-Tell Conversations With Gender-Creative Children, Eline Leemans Lenne

Dissertations and Theses

A growing number of children identify in various gender-creative ways, likely due to broader social awareness and affirmation of transgenderism. Gender-creative children face higher risks for adverse social, academic, mental health, and healthcare outcomes compared to non-transgender peers. Support from loved ones along with guidance from pediatric providers can mitigate poor outcomes and ensure that gender-creative children live healthy and happy lives. Young gender-creative children's perspectives about the aforementioned topics are markedly absent from the literature, which instead highlights adolescent and adult proxy perspectives.

In this participatory arts-based study anchored by a constructivist epistemology and informed by post-structuralist, queer, and …

An Equitable End: Meeting The Needs Of Queer Families Within Deathcare, Nyssa Peck

University Honors Theses

This thesis seeks to explore end-of-life care experiences of queer families, focusing on interactions with palliative and hospice caregivers. Currently, end-of-life (EOL) practitioners in institutional and medical care settings are often poorly equipped to interact with queer families due to inadequate cultural training models, personal biases, and ignorance regarding the queer identities of their clients. This manifests in substantial inequities within deathcare systems regarding the accommodation of the unique needs of queer familial structures. Drawing upon multidisciplinary scholarship, I sought to examine these needs, which diverge from that of heterosexual families due to queer families’ absence of legal protections and …

Beyond The Bickering: Examining Event, Victim, And Offender Characteristics For Sibling Abuse Incidents In Oregon, Isabella M. Starr

University Honors Theses

Sibling violence (SV) is the most prevalent form of intrafamilial and domestic violence, yet it remains underrecognized and lacks the systematic attention given to other forms of family violence. Often minimized or misclassified as typical sibling rivalry, SV can inflict serious and lasting physical, emotional, and psychological harm on its victims. This study explores the characteristics of sibling violence incidents reported to law enforcement in Oregon between 2016 and 2023, using data from the National Incident-Based Reporting System (NIBRS). Through an analysis of 5,793 single-victim, single-offender incidents, the research examines demographic patterns among victims and offenders, incident dynamics, and typological …

Diverse Microbial Prey In The Guts Of Gelatinous Grazers Revealed By Microscopy, Terra C. Hiebert, Anne W. Thompson, Kelly R. Sutherland

Biology Faculty Publications and Presentations

Mucous mesh grazers including pelagic tunicates and thecosome pteropods play a key role in oceanic food webs. They are taxonomically and morphologically diverse and can be highly abundant. Using their fine mucous meshes, these pelagic grazers ingest a wide range of plankton prey and link pelagic and benthic marine ecosystems. Characterizing the diet of this group is central to fully understanding marine food webs and developing accurate food web models. However, gelatinous grazers are challenging to study owing to their physically delicate composition so studying their feeding ecology requires numerous complementary techniques. Microscopy has largely been supplanted by other methods, …

Seabed Characterization Using Ambient Sound For A Range-Dependent Track In The New England Mud Patcha, Martin Siderius, Stan E. Dosso, Brian Granger

Electrical and Computer Engineering Faculty Publications and Presentations

Wind-generated, ocean ambient sound data were used to characterize seabed properties along a track in the New England Mud Patch. A 15-m vertical array, consisting of 16 hydrophones, collected ambient sound data across the 50–5000 Hz frequency band. The array drifted for 1 h, covering a 1.7 km track. Seabed characterization was performed using beamforming techniques, which limited the analysis to the 400–700 Hz band. Passive fathometer processing was applied to estimate the water–seabed interface and sub-bottom layering. Additionally, the data were used to estimate the power reflection coefficient, which was then used as input for a trans-dimensional geoacoustic inversion. …

Accelerating High-Throughput Phonon Calculations Via Machine Learning Universal Potentials, Huiju Lee, Vinay I. Hegde, Chris Wolverton, Yi Xia

Mechanical and Materials Engineering Faculty Publications and Presentations

Phonons play a critical role in determining various material properties, but conventional methods for phonon calculations are computationally intensive, limiting their broad applicability. In this study, we present an approach to accelerate high-throughput harmonic phonon calculations using machine learning universal potentials (MLIPs) combined with an efficient training dataset generation strategy. Instead of computing phonon properties from a large number of supercells with small atomic displacements of a single atom, our approach uses a smaller subset of supercell structures where all atoms are randomly displaced by 0.01 to 0.05 UŮ, significantly reducing computational costs. We train a state-of-the-art MLIP based on …

Reform For "These" Kids: Neoliberal Reform, Theorized Target Populations, And Spatial Injustice, Matthew S. Mccluskey, Madhu Narayanan, Erin Milne

Educational Leadership and Policy Faculty Publications and Presentations

Charter schools were originally envisioned as laboratories of innovation, but we have scant empirical evidence of how charter policies and ideas have spread beyond charter walls into the wider educational landscape. The diffusion of knowledge reflects networks of power, and tracing diffusion can unearth the discursive and power dynamics at play. Using a systematic search of publicly-available documents, this study investigated the geographic diffusion of one Charter Management Organization (CMO)—Uncommon Schools—as a case of charter discursive diffusion. Grounded in Critical Policy Analysis (CPA), we found that artifacts were located disproportionately in higher poverty zip codes housing lower percentages of non-Hispanic …

Digital Child Labor Exploitation In Sharenting: Proposing Legislative Solutions For Enhanced Child Protection, Joana Guzman Gonzalez

Through a comprehensive literature review, the research examines children's online presence's emotional, legal, and societal impacts, drawing from case studies such as Sheri Franke, Wren Eleanor, Ryan Kaji, and JoJo Siwa. The analysis reveals a …

Disrupting The Abuse-Prison Nexus: The Gendered Violence Of Prosecution And Abolitionist Feminist Approaches To Social Care Work, Sid P. Jordan, Emily Thuma, Aylaliyah Assefa Birru, Deirdre Wilson, Romarilyn Ralston, Norma Cumpian, Joseph Hankins

School of Social Work Faculty Publications and Presentations

The vast majority of people in U.S. women’s prisons are survivors of interpersonal violence, a pattern that organizers and advocates have referred to as the abuse-to-prison pipeline. This article critically examines criminal prosecution from the perspectives of survivors of interpersonal violence who faced long prison sentences in California. In-depth interviews and group discussions were generated through a participatory process at a gathering to launch the University of California Sentencing Project, a partnership with the community-based organization California Coalition for Women Prisoners. The twenty-two formerly incarcerated participants had collectively spent more than 300 years imprisoned. Drawing on their lived experiences spanning …

Collaboration Through Trust Building: Building Trust Among Racialized And Stigmatized Nonprofits, Shariq Siddiqui, Abdul Samad, Rafeel Wasif

Public Administration Faculty Publications and Presentations

Nonprofits collaborate to resolve common issues while improving program effectiveness and reducing replication. These collaborations can be critical for minority nonprofits in resolving their common problems. However, while literature often looks at nonprofit organizations working with the government or other organizations, it does not focus on how minority nonprofits can collaborate better with other minority organizations. Using Muslim American nonprofits as a case study, we understand better how trust can be built between nonprofits belonging to marginalized communities. We focus on the Community Collaboration Initiative, a three-year third-party-facilitated collaboration effort among Muslim-American nonprofits. Overall, Interpersonal relationships, organizational learning, and positive …

College Outcomes For Young Adults With And Without Learning Disabilities And Adhd: Formal-Disability-Programming And Informal-Disability-Supports, Dara R. Shifrer, Rachel Springer, Hannah Sean Ellefritz, Ned Tilbrook

Sociology Faculty Publications and Presentations

Inequalities by disability status in college outcomes contribute to inequalities throughout adulthood in multiple domains. As the share of students with learning disabilities and/or ADHD increases on college campuses, research is needed on how best to support these undergraduates, both through formal and informal means. We integrate the social and medical models of disability with data on nearly 17,000 young adults in the US, who typically finished high school in 2013, and find that formal-disability-programming relates negatively to college enrollment but has no apparent bearing on college persistence. Among youth with similar sociodemographic backgrounds and comparable end of high school …

Hamza, Mohamed Sholqamy, Multiple Additional Authors

Civil and Environmental Engineering Faculty Publications and Presentations

Abstract While non-destructive testing (NDT) measurements have been reported individually for archeological surveys of cultural heritage structures, only a few studies to date have attempted to combine NDT images by means of image fusion (IF). In this article, novel multimodal IF results from three different NDT techniques collected at the Chevron located on the Great Pyramid of Giza (aka. as Khufu’s Pyramid) are presented. The Chevron is an assembly of limestone blocks located in front of the recently confirmed ScanPyramids North Face Corridor (SP-NFC), which had been previously hidden for 4500 years. Under the research activities of the ScanPyramids mission, …

Between Fire And Water: Miyazawa Kenji's Reimagining Of Opposites In Ginga Tetsudō No Yoru, Taishi Neilsen

University Honors Theses

This thesis explores how Japanese writer Miyazawa Kenji playfully uses opposites and binaries to create thematic richness in his famous children's story Ginga tetsudō no yoru (Night on the Milky Way Railroad). Despite being a children's book, the text works with mature themes such as loneliness, grief, and purpose, themes which are elevated through Kenji's idiosyncratic stylings. Through a close reading of the original Japanese text, the author isolates moments where Kenji conveys his Nichiren Buddhist worldview as part of his proselytizing mission, as well as moments that increase thematic richness, resulting in a multifaceted text that continues …

Investigating Key Structures In Protective Scenes For Llms, Eben M. Weisman

University Honors Theses

This research delves into the realm of "protective scenes" within Large Language Models (LLMs), exploring their impact on bias mitigation, deception, and context preservation. The study investigates the use of roleplay prompting human-like behavior and reasoning in LLMs, focusing on the Character-LLM framework's concept of protective scenes with graduated levels of protection. By combining insights from psychology, cognitive science, and computational analysis, this research aims to develop a framework for understanding how protective scenes influence roleplay performance in LLMs, ultimately contributing to the development of more reliable and ethical AI systems.

Abiotic Variables Drive Different Aspects Of Fish Community Trait Variation And Species Richness Across The Continental United States, Alicia Mcgrew, Crysta Gantz, Brigid Wills, Benjamin Baiser, Sydne Record, Phoebe L. Zarnetske, Angela L. Strecker

Environmental Science and Management Faculty Publications and Presentations

Intraspecific trait variation (ITV) is an increasingly important aspect of biodiversity and can provide a more complete perspective on how abiotic and biotic processes affect individuals, species' niches and ultimately community-level structure than traditional uses of trait means. Body size serves as a proxy for a suite of traits that govern species' niches. Distributions of co-occurring species body sizes can inform niche overlap, relate to species richness and uncover mechanistic drivers of diversity. We leveraged individual-level body size (length) in freshwater fishes and environmental data from the National Ecological Observatory Network (NEON) for 17 lakes and streams in the contiguous …

Working Paper No. 89, Towards A Veblenian View Of The Digital Realm, Tanner Weber

Working Papers in Economics

This inquiry seeks to establish that Thorstein Veblen’s writings offered insights that could assist us in understanding the digital realm in contemporary times. Through advancing his thinking for dealing with the instincts of idle curiosity and workmanship, in particular, Veblen provided an understanding of capital as technologies, especially, that should be valued as contributions to the common and joint stocks of knowledge. Back in his day, Veblen’s understanding of capital, ownership, and private property offered ways for us to think of some of the potential usages of technology as well as a range of possibilities for sabotage. What …

Comparative Soil Health In Urban Agrofrestry: A Case Study On Detroit's Perennial Agriculture Sites, Nia Dubon-Robinson

Urban Ecosystem Research Consortium of Portland/Vancouver

Urban ecosystems are being intentionally developed to enhance innovation and resilience, addressing various community needs. Urban agriculture, particularly, involves cultivating food on soils affected by industrial activities. Urban agroforestry serves as a strategy to generate ecosystem services while increasing the availability of regionally adapted fruit and nut trees. Unlike annual crop production, agroforestry initiatives require less extensive soil management and labor, which can in turn enhance soil health. This case study examines soil health indicators—physical (bulk density), chemical (soil organic matter fractions), and biological (microbial diversity)—in one young urban food forest compared to two older conventional urban orchards in Detroit, …

Enhancing Discoverability: Transitioning A Board Game Collection From A Libguide To A Collectionbuilder Site, Hanwen Dong, Perri Moreno, Tyler Rodriguez, Julia Stone

Library Faculty and Staff Publications and Presentations

As board game collections continue to grow in popularity at academic institutions, the University of Idaho Library wanted to establish an accessible and easy-to-use discovery tool for its physical game collection. At the collections’ origins, a LibGuide was created by librarians for this purpose, but as the collection records continued to grow into the triple digits, something more adaptable and customizable was necessary. In the summer of 2023, a team of librarians came together to build a custom site to house the game collection’s information using CollectionBuilder, an open-source framework for digital collections and exhibits websites that are driven by …

Urban Beavers At The Crossroads: How Ecological Knowledge, Sociodemographic, And Spatial Context Shape Public Perception And Coexistence Preferences, Matthew Guziejka

Dissertations and Theses

Urban beavers demonstrate synurbization by adapting to urban environments, offering ecological benefits such as biodiversity enhancement and flood mitigation, while also occasionally conflicting with infrastructure. This study examines how ecological knowledge, sociodemographics, and spatial context influence public perceptions and management preferences for urban beavers in the Tualatin River watershed, Oregon.

A voluntary survey of 176 participants from peri-urban areas assessed demographic characteristics, ecological knowledge, and attitudes toward management approaches. Spatial factors, such as proximity to watercourses and green spaces, were also analyzed. Logistic regression analyses were used to explore relationships between these factors and management preferences. Political orientation was significantly …

Electrical and Computer Engineering Faculty Publications and Presentations

Gait assessments in a clinical setting may not accurately reflect mobility in everyday life. To better understand gait during daily life, we compared measures that discriminated Friedreich ataxia (FRDA) from healthy control (HC) subjects in prescribed clinic tests and free, daily-life monitoring.MethodsWe recruited 9 people with FRDA (median age: 20, IQR [12, 48] years). A comparative healthy control (HC) subject cohort of 9 was sampled using propensity matching on age (median age: 18 [13, 22] years). Subjects wore 3 inertial sensors (one each foot and lower back) in the laboratory during a 2-min walk at a natural pace, followed by …

Color Aberrations In Seven Bird Species In Costa Rica, Lucia Isabel Lopez, Jose Manuel Mora, Adrian Alvarado Rivera

Biology Faculty Publications and Presentations

Although there are 935 species of birds in Costa Rica, scientific reports of pigmentation abnormalities in this group are limited. Nevertheless, several cases have been recently documented, including Leucism, Ino mutation, Progressive Graying, Dilution, and two unusual color aberrations in a toucan and a motmot. Here we describe seven cases of color aberrations observed over a period of five years in native birds of Costa Rica. An Eastern Wood-Pewee Contopus virens and a White-collared Manakin manacus candei were Brown. A Scintillant Hummingbird Selasphorus scintilla and a Talamanca Hummingbird, Eugenes spectabilis, also showed a Brown mutation, however, these two cases may …

Working Paper No. 88, Algorithms And Thorstein Veblen’S ‘Machine Process’, Eunji Jang

Working Papers in Economics

This inquiry seeks to establish that the ‘machine process’ which Thorstein Veblen introduced into the Economics literature back in 1904, exhibits similarities to algorithms that are readily found in contemporary times--more than one hundred years on. In The Theory of Business Enterprise [1904] (2005), Veblen defines the machine process as a system that prioritizes efficiency, standardization, and automation. Relatedly, this inquiry argues that algorithms are based upon similar principles and exhibit similar tendencies that yield similar outcomes. Additionally, this inquiry explores the institutional role of algorithms, elaborating upon how their increasing prevalence and solidification might serve to enhance efficiency in …

Working Paper No. 87, The Double-Edged Sword Of American Philanthropy, Nathan Lewis-Lusso

Working Papers in Economics

This inquiry seeks to establish that American philanthropy, often hailed as a moral virtue, is in part a reflection of systemic policy failures that have forced private individuals to address public needs. While one blade of the philanthropic sword has historically provided essential support in areas such as education, healthcare, and poverty alleviation, the other blade of the sword has also allowed for wealthy individuals to shape public priorities, often reinforcing existing inequalities. By analyzing the historical development of philanthropy, its role in addressing policy gaps, and its potential in undermining democratic governance, this inquiry highlights the complex and often …

Adaptive Resolution Of Fine Scales In Modes Of Microstructured Optical Fibers, Jay Gopalakrishnan, Jacob Grosek, Gabriel Pinochet-Soto, Pieter Vandenberge

Mathematics and Statistics Faculty Publications and Presentations

An adaptive algorithm for computing eigenmodes and propagation constants of optical fibers is proposed. The algorithm is built using a dual-weighted residual error estimator. The residuals are based on the eigensystem for leaky hybrid modes obtained from Maxwell equations truncated to a finite domain after a transformation by a perfectly matched layer. The adaptive algorithm is then applied to compute practically interesting modes for multiple fiber microstructures. Emerging microstructured optical fibers are characterized by complex geometrical features in their transverse cross section. Their leaky modes, useful for confining and propagating light in their cores, often exhibit fine-scale features. The adaptive …

Accessible Bike Map Design: A Review And Critique Of Portland’S Bike Maps, Zachary Cheyney

Geography Masters Research Papers

Urban bike maps can serve as key tools for route planning and navigation for prospective cyclists, providing both general information (such as landmarks and natural features) and cycling specific information (such as bike lane infrastructure types and cycling amenities). Despite this, there is little professional guidance or academic research on best practices for bike map design. Potential guidance should consider the full range of potential cyclists, including disabled cyclists who have often been left out of cycling policy discussions. In this paper, I begin by discussing 3 case studies on participatory mapping methodologies with disabled participants in order to generate …

By analyzing the ongoing impact of conservation frameworks in Kenya, this research highlights the role of Indigenous-led initiatives in advancing sustainable, community-driven alternatives. Using a Two-Eyed Seeing approach, which integrates Traditional Ecological Knowledge (TEK) with Western scientific methods, the study employs qualitative, semi-structured interviews with leaders from Zawadisha, KENVO, Wildlife Works, and CER-Kenya. Findings indicate that these organizations, particularly those led by women, actively restore biodiversity, enhance climate resilience, and challenge exclusionary conservation policies. …

Risk Factors For Substance Use Among Serious And Violent Offenders Undergoing Reentry, Elizabeth Bozarth

University Honors Theses

Formerly incarcerated individuals often experience an intensely chaotic and stressful reentry environment, riddled with barriers and challenges that make them more susceptible to substance use and other risky behaviors. This literature review focuses on the most prevalent and pervasive risk factors for substance use among serious and violent offenders undergoing reentry. By examining research published within the last decade on serious and violent offenders in the United States, several major themes were identified: social bonds, housing and employment, mental health, and surveillance and addiction treatment. The results showed that risk factors for substance use are deeply embedded in ex-offenders' social …
