How Was Your Crossing Experience? Development Of A Pedestrian Satisfaction With Unsignalized Crossings Scale, Seth Lajeunesse, Wesley Kumfer, Sirisha Kothuri, Krista Nordback, Nathan Mcneil

Civil and Environmental Engineering Faculty Publications and Presentations

Unsignalized pedestrian crossing accommodations can improve pedestrian safety, yet their quality of service for pedestrians remains understudied. The present study explored whether and how pedestrians’ satisfaction with crossing unsignalized crossings varied according to the type of crossing accommodation used, that is, the rectangular rapid-flashing beacon (RRFB) with median island, median island alone, marked crosswalk, and unmarked crosswalk. The research team collected intercept survey and video observation data from 358 pedestrians across a total of 40 sites in two different cities. Structural equation models illustrated how pedestrians’ crossing-oriented satisfaction was shaped by their positive perceptions of safety and low levels of …

Pumped Storage Hydropower In The United States: Emerging Importance, Environmental And Social Impacts, And Critical Considerations, Surabhi Karambelkar, Alida Cantor, Thien-Kim Bui, Bethani Turley, Maryalice Fischer, Shannon Ames

Drawing on published research from both technical and social science perspectives, this paper provides an overview of pumped storage hydropower technology, the project development pipeline, potential social and environmental impacts, including a comparison of open-loop and closed-loop design configurations, and critical considerations for project development. …

Performance Methodologies In Suicide Prevention Research: Queerness, Colonization, And Co-Performative Witnessing In Indigenous Community, Antonia R. G. Alvarez

School of Social Work Faculty Publications and Presentations

Performance methodologies take many forms—performative writing, poetic transcription, and co-performative witnessing, to name only a few—and can be both process and product, differentiating and unifying a group between and across differences. As a social work researcher committed to decolonial, liberatory methodologies that make and bring meaning to the communities I work with, performance methodologies fill a gap that other qualitative research methods can only begin to approach. This project is an exploration in performance methodologies and Critical Suicidology through the lens of social work research, with a case study derived from a performance documenting suicide prevention research with Native Hawaiians. …

Tree-Equity And Environmental Justice Discourses Among Urban Forestry Professionals In Portland: Current Impacts And Future Implications, Axcelle Deone Bell

Dissertations and Theses

Urban tree equity is critical for addressing environmental justice and mitigating the effects of climate change in cities. This study investigates how professionals in Portland's urban forestry sector conceptualize and implement tree equity, focusing on equity and justice discourses. Through 27 semi-structured interviews with 29 professionals from government agencies and NGOs, I examine how these discourses shape decisions regarding tree planting, distribution, and maintenance, particularly in underserved communities. The analysis draws on political ecology, systems dynamics, and structuration theory to explore the systemic barriers perpetuating inequities in tree canopy distribution. The findings reveal tensions between different approaches to equity, such …

Forest Fires Increase Mid-Winter Snowmelt In The Western Oregon Cascades, Sage Ebel

Dissertations and Theses

As the spatiotemporal overlap between burned forests, seasonal snow, extreme precipitation, and mid-winter warming continues to increase with climate change, it is critical we quantify the impacts of forest fires and rain-on-snow (ROS) on mid-winter snowmelt and snow-water resources. In the Pacific Northwest, the release of large volumes of meltwater to downstream receiving water from already vulnerable snowpacks can have catastrophic consequences. I show that forest fires doubled mid-winter snowmelt proportions as compared to unburned reference sites, using a novel network of snow monitoring and micrometeorological stations installed across an elevational and forest type gradient in a burned watershed in …

Integrative Approaches To Climate Resilience Planning: Application Of A Plan Evaluation Framework, Maulsri Jha

Dissertations and Theses

In the last two decades, urban governments have streamlined and prioritized the creation and implementation of climate resilience plans to cater to the communities' vulnerabilities. Existing research illustrates that there is a gap in understanding how, or if, empirical (evidence-based) data are incorporated into the design and implementation of such plans and the extent to which their inclusion impacts outcomes in terms of vulnerability reduction. There is also a gap in the systematic study of their outcomes in terms of community resilience, and whether equity and environmental justice are promoted as priorities.

The purpose of the research is to understand …

Gatekeeping As An Online Adjunct Clinical Instructor In Counselor Education, Bernadet Dejonge, Deborah J. Rubel, Yun Shi

Counselor Education Faculty Publications and Presentations

This interpretative phenomenological analysis study examined how adjunct instructors teaching online clinical counseling courses experienced gatekeeping in the context of the university system. The research question was: How do online, adjunct instructors teaching master’s level clinical counseling courses experience their university interactions as a part of gatekeeping? The participants described five experiential themes. These were: a) Balancing marginalization in the system with advocacy for the profession; b) Maneuvering through dependency on the system in gatekeeping; c) Finding consultation while navigating gatekeeping interactions; d) Managing the intensity of clinical courses; and e) Navigating the steep learning curve of learning how to …

Forging Common Ground In Second Language Acquisition And Teaching: A Combined Synergy Statement, Marije Michel, Dwight Atkinson, Amable Custodio Ribeiro, Theodora Alexopoulou, Marco Cappellini, Søren Wind Eskildsen, Xuesong (Andy) Gao, John Hellermann, Hayriye Kayi‐Aydar, Steven L. Thorne, Multiple Additional Authors

The findings reveal a growing governance network centered on the USDA Forest Service and the Idaho Department of Lands and supported by numerous non-governmental organizations and …

I Love That Country, That’S Why I Go There: Enduring Kiana Village Ties To Kobuk Valley National Park, Douglas Deur, Jamie Hebert, Emily Creek, Tricia Brown, Hannah Atkinson, Knowledge-Holders Of Kiana, Alaska, Christina Westlake

Anthropology Faculty Publications and Presentations

North of the Arctic Circle in far northwestern Alaska, Kobuk Valley National Park is a remote, roadless protected area transected by the Kobuk River—one of the northernmost salmon-bearing rivers in North America. Characterized by tundra, taiga, and the dramatic 25-square-mile Great Kobuk Sand Dunes, the park serves as a critical pathway for nearly half a million migrating caribou. Significant archaeological sites have been documented along the Kobuk River, demonstrating thousands of years of human settlement, fishing, caribou hunting, and many other cultural activities. At the time of European contact, and into the early 20th century, there were still Iñupiaq “Eskimo” …

Welcoming Historically Under-Represented Groups In Higher Education Through Awareness Of Standard English Ideology, John Hellermann, Lynn Santelmann, Jennifer Mittelstaedt, Janet Cowal, Steven L. Thorne

Applied Linguistics Faculty Publications and Presentations

In the context of changing demographics at regional universities (including our own), we highlight an ongoing project at our university that addresses the last area of acceptable bias in English-medium higher education: bias against speakers of other languages and non-standard dialects of English. We discuss the hegemonic aspect of the Standard Academic English used by default at most US institutions of higher education and its role in potential discrimination against users of languages other than English and dialects other than the Standard. Data from over 2000 surveys, 55 follow up interviews, and three focus groups from faculty, staff and students …

This project report, completed on behalf of Learning Landscapes, uses qualitative evidence from interviews with school district administrators, teachers, volunteers, grounds staff, city employees, and outreach experts to gain a deeper understanding of the factors leading to successful collaboration between local school districts and their external community partners. These conversations with school and outreach personnel across the city suggest that district staff are interested in collaborative greening organizations like Learning Landscapes …

Portland's Urban Doom Loop, Noah Rappaport, Avery Kageyama, Austen Knight

Business Faculty Publications and Presentations

In this analysis we define the system boundary as Portland's downtown core, encompassing the downtown and immediately adjacent districts immediately affected by the effects of the "Urban Doom Loop." We selected this boundary for the concentration of reinforcing feedback loops. In Portland's downtown core remote work, commercial vacancy, homelessness, public safety concerns, and narrative media depiction of decline converge and amplify each other most intensely. Media focus on downtown disproportionately shapes public perceptions of the entire city. Interventions by city agencies are being proposed to take place there. While acknowledging that Portland's challenges extend beyond the downtown core, we intentionally …

"Where Will My Family Go?" The Financial, Housing, And Health Challenges Of Families Facing Eviction, Natalie J. Cholula, Alex Farrington, Lisa K. Bates, Marisa A. Zapata, Jacen Greene

Urban Studies and Planning Faculty Publications and Presentations

To better understand how eviction affects families with children, the Evicted in Oregon team conducted focus groups with 74 tenants from Baker, Lincoln, Linn, Marion, Multnomah, and Washington counties in Oregon. During focus group discussions, we asked participants whether they had children in the household at the time of eviction and how it impacted them. Parents reported that their children’s well-being was their main concern during the eviction process. They also described how eviction led to disruptions in their children’s education, health and medical treatments, and living arrangements. Based on our findings, we provide a set of policy and program …

Elements Of Social Capital And Counterspace Processes Contribute To Undergraduate Stem Student Development Of A Sense Of Belonging, Mackenzie J. Gray, Jasmine N. Yacobian, Erin Shortlidge

Biology Faculty Publications and Presentations

Having a sense of belonging can promote persistence in the STEM fields, but less is known about what it means to develop that sense of belonging. To investigate this phenomenon, we conducted semi‐structured interviews with a cohort of STEM students (n = 10) nearing graduation at an urban university regarding their sense of belonging and qualitatively coded the interviews using thematic analysis. Results revealed that all interviewed students clearly articulated feelings of belonging, making them an ideal population from which to learn more. We applied two frameworks to guide our understanding of what factors promoted the development of a sense …

Individualized Deals For Overqualified Employees: An Investigation Of Supervisor Perceptions Of Employee Overqualification, Farid Jahantab, Berrin Erdogan, Prajya R. Vidyarthi, Smriti Anand

Business Faculty Publications and Presentations

In this study, we extend overqualification research by examining the indirect relationship between supervisor perceptions of employee overqualification and performance outcomes via task i-deals. We predict that employees are more likely to be granted task i-deals to the degree to which they are perceived as overqualified by their supervisors, which in turn indirectly and positively affects their task performance and citizenship behaviors. Further, we expect the relationship between supervisor-rated overqualification and task i-deals to be stronger when supervisor perceived peer overqualification and workgroup team orientation are lower. Analyses of multi-wave multi-source data from 682 employees nested in 115 workgroups in …

Recontextualizing Engagement With Data Visualizations In The Context Of The Socio-Ecological, Eva Thanheiser, Laurie Rubel, Beth Herbel-Eisenmann, Courtney Koestler

Mathematics and Statistics Faculty Publications and Presentations

We explore how data visualizations (DVs) are representational tools that can be used to narrate certain aspects of a context but silence others. Using multiple DVs allows for contrasting the DVs and likely provides opportunities for critical reading and exploring the entanglement of political and ecological dimensions of an issue. We start by integrating two sets of practices, Notice, Wonder, Feel, Act and Reimagine (NW-FAR) (Kahn, et al., 2022) and critical graph reading, Framing, Formatting, Narrating (FFN) (Rubel, et al., 2021) towards taking a socio-political stance and supporting students to read data visualizations and develop critical data literacy. We look …

The Adaptive Roles Framework: Trauma Adaptations And Identity Formation, Steffannie Roache

School of Social Work Faculty Publications and Presentations

The Adaptive Roles Framework is a culturally grounded conceptual model that explains how individuals develop patterned behavioral, emotional, and relational strategies in response to family systems, culture, trauma exposure, and social environments. Rather than conceptualizing behavior through pathology or personality typology, the framework positions behavioral patterns as adaptive survival strategies, responses that increased safety, belonging, or stability within specific environments and were reinforced over time because they worked. The framework identifies seven adaptive roles observed consistently across individuals, families, workplaces, and communities: the Guardian, the Translator, the Assimilator, the Archive Keeper, the Time Jumper, the Intellectual Escape Artist, and the …

How Do Patient-Provider Relationships Affect Patient Satisfaction?, Rose D. Lightspeed

Anthós

This article reviews studies on patient satisfaction within the U.S. healthcare system to investigate how physicians’ behavior influences patients’ reported quality of care. Medical negligence, neglect, and cognitive biases are identified from the reviewed literature as physician behaviors that affect the patient-provider relationship and patient satisfaction. Emphasizing patient satisfaction and involvement in their care as important considerations when evaluating patient-provider relationships, Lightspeed underscores how the complex dynamic between patient and provider–including physicians’ reported feeling of inadequate interpersonal skills and patients’ sensitivity to dismissive communication–contributes to reduced satisfaction rates. Lightspeed argues that increasing physician awareness of these factors that influence patient …

Sound, Touch, And Place: An Exploratory Study Of The Potential For Emotive Cognitive Mapping Through The Use Of Audio Description And Tactile Objects At A National Memorial, Amy Parker, Haruka Hopper, Kira Swearingen, Leah Neumann Samson, Brett Oppegaard, Hazelle Magaoay-Baniaga, Mary-Clare Cable

Leadership, Learning and Counseling Faculty Publications and Presentations

Audio description, tactile objects, and memorial sites are often studied separately for their communicative and emotive potential without consideration of potential multimodal connections existing among people, technologies, and solemn public places. This study’s novel mixed-methods approach uses site tours, surveys, think-aloud protocol, semi-structured interviews, and observations to develop rich and holistic understandings of such complex multimodal site visits at Pearl Harbor National Memorial in Hawai‘i by people who are DeafBlind, blind, or with low vision. Several themes emerged in the grounded empirical data gathered during the tour, afterward, and during an interview one month later, including findings that bridged emotions, …

Optical Coherence Tomography Harmonization With Anatomy-Guided Latent Metric Schrödinger Bridges, Shuwen Wei, Blake E. Dewey, Samuel W. Remedios, Bruno Jedynak, Shimeng Wang, Peter Calabresi, Shiv Saidha, Aaron Carass, Multiple Additional Authors

Mathematics and Statistics Faculty Publications and Presentations

Medical image harmonization aims to reduce the differences in appearance caused by scanner hardware variations to allow for consistent and reliable comparisons across devices. Harmonization based on paired images from different devices has limited applicability in real-world clinical settings. On the other hand, unpaired harmonization typically does not guarantee anatomy consistency, which is problematic because anatomical information preservation is paramount. The Schrödinger bridge framework has achieved state-of-the-art style transfer performance with natural images by matching distributions of unpaired images, but this approach can also introduce anatomy changes when applied to medical images. We show that such changes occur because the …

Unsupervised Oct Image Interpolation Using Deformable Registration And Generative Models, Shuwen Wei, Samuel W. Remedios, Bruno Jedynak, Peter Calabresi, Shiv Saidha, Aaron Carass, Multiple Additional Authors

Mathematics and Statistics Faculty Publications and Presentations

Optical coherence tomography (OCT) images are often acquired as highly anisotropic volumes, where the scanning step is dense along the fast axis but sparse along the slow axis. This affects image analysis, such as image registration for longitudinal alignment. To create more isotropic volumes, bicubic interpolation can be used along the slow axis, but it generally produces blurry features. Registration-based interpolation can reduce blurriness, but often fails to generate realistic OCT images. Deep generative models can sample realistic images, but lack the structural consistency constraints required for interpolation. In this paper, we propose an unsupervised image interpolation method that combines …

Historicity And Axiology: Temporal Implications For Axiology, Bennett Gilbert

History Faculty Publications and Presentations

To develop the axiology of moral (or ethical) values, phenomenological analysis must look at temporality in a way that is unfamiliar to it. This way is through knowledge and experience of the actual historical past, from which it has been separated by the Heideggerian conception of historicity and its classical Husserlian analysis of time consciousness. The development of historical studies helps to make this possible. A simple sample model of the diachronesis of the awareness of ethical significance, value, and obligation is presented. It moves the analysis from a presentist focus to the field of experience in which subjects develop …

History’S Movement: The Historical Ontology In Social Ontology, Bennett B. Gilbert

History Faculty Publications and Presentations

Social ontology and the philosophy of history both concern themselves with human collectives. Social ontology is supposed to be theoretical, although the social sciences are supposed to be empirical. Philosophy of history is supposed to be theoretical, although historiography is supposed to be empirical. In fact, the a priori and the a posteriori mix in both theoretical and empirical endeavors in similar ways. Since the two endeavors hold part of their objects of inquiry in common, they should be able to speak to another. In what follows I aim to expose some of the ways their dialogue stresses and can …

Interdependence And Identity: Moral Relation In An Historical World, Bennett B. Gilbert

History Faculty Publications and Presentations

The twin concepts in the title will be introduced in the contexts of the philosophy of history and of philosophical personalism, as distinct from (though related to) their uses as logical and metaphysical categories. Overviews of varieties of philosophy of history and of basic principles I employ are foundations of the argument. Concepts, or ideas, in general have, I argue, real existence through the way that personal agents use them in creating the histories of human relations. I introduce a Personalist account, which has a more thoroughly diachronic character. Further remarks on the power of ideas to create relations expands …

The Life Of Or Measure 110: Evolution, Implementation, And Impact, Matthew D. Albertson

Anthós

In 2020, Oregon voters approved Measure 110, a groundbreaking policy that decriminalized possession of small quantities of controlled substances and redirected cannabis tax revenues to treatment and recovery centers. This article examines the passage, implementation, and rollback of Measure 110 with HB 4002, enacted in 2024. Drawing on state audits, legislative records, and public health data to contextualize Measure 110 within broader debates on public health, criminal justice reform, and policy-making, Albertson analyzes the progressive policy’s aspirational, reform-minded goals and the practical shortcomings in its enactment. Albertson argues that while Measure 110 has faced justified criticism and partial reversal, it …

The Tyrant King Of The Auction House: The Disastrous “Fine Artification” Of The Dinosaur, Amelia C. Kolstad

Anthós

This article examines how fine art auctioneers market dinosaur fossils as art pieces to wealthy collectors, depriving the paleontological field of specimens for scientific research. Drawing from recent examples of fossils sold at fine art auctions, this article notes how rising auction prices for specimens as ‘art’ prevent museums and research institutions from acquiring specimens for research and restoration. Kolstad concludes that the art auction houses’ marketing of fossils as art is detrimental to paleontological research. To protect fossils and their scientific value, Kolstad proposes alternatives, such as selling replicas to collectors and highlighting the importance of original specimens for …
