“Lost-In-The-Later”: Framework For Quantifying Contextual Grounding In Large Language Models, Yufei Tao, Adam Hiatt, Rahul Seetharaman, Ameeta Agrawal

Computer Science Faculty Publications and Presentations

Large language models (LLMs) are capable of leveraging both contextual and parametric knowledge but how they prioritize and integrate these sources remains underexplored. We introduce CoPE, a novel framework for systematically quantifying contextual grounding in LLMs. CoPE distinguishes between contextual knowledge (CK) and parametric knowledge (PK), enabling fine-grained attribution across languages and tasks. Using our newly created MultiWikiAtomic dataset in English, Spanish, and Danish, we analyze how LLMs integrate context, prioritize information, and incorporate PK in open-ended question answering. We find that across models and languages, only around 50 to 76 percent of outputs are grounded in the given context, …

Retrieval-Augmented Feature Generation For Domain-Specific Classification, Xinhao Zhang, Jinghan Zhang, Fengran Mo, Dakshak Keerthi Chandra, Yu-Zhong Chen, Fei Xie, Kunpeng Liu

Computer Science Faculty Publications and Presentations

Feature generation can significantly enhance learning outcomes, particularly for tasks with limited data. An effective way to improve feature generation is to expand the current feature space using existing features and enriching the informational content. However, generating new, interpretable features usually requires domain-specific knowledge on top of the existing features. In this paper, we introduce a Retrieval-Augmented Feature Generation method, RAFG, to generate useful and explainable features specific to domain classification tasks. To increase the interpretability of the generated features, we conduct knowledge retrieval among the existing features in the domain to identify potential feature associations. These associations are expected …

Conceptualising Coercion In Child/Forced Marriage Through An Intersectional Lens: Narratives Of Survivors And Practitioners In The Us, Sundari Anitha, Manjusha Gupte

Women, Gender, and Sexuality Studies Faculty Publications and Presentations

This article examines the nature and forms of coercion in the forced marriage of minors in the US. We explore: (i) direct emotional or physical force exercised by parents which is commonly underpinned by dominant constructions of gender and sexuality, a well-rehearsed theme in existing scholarship; (ii) the hitherto unexamined role of intersecting socio-economic disadvantages in vitiating consent; and (iii) how state policies/practices create conducive contexts for child/forced marriage, which is elided in existing scholarship. In extending existing conceptualisations of coercion in child/forced marriage, we explicate the ‘total burden of coercion’ through a focus on the contexts within which consent …

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 …

2024 Oregon Statewide Homelessness Estimates, Franklin H. Spurbeck, Jacen Greene, Marisa Zapata

Homelessness Research & Action Collaborative Publications and Presentations

The Point-in-Time (PIT) Count is a census of people experiencing both sheltered and unsheltered homelessness on a single night in January. The federal government requires this at least every other year as a condition of funding it distributes to Continuums of Care (CoCs), networks of government agencies and service providers that manage homelessness services and funding in specific regions. The unsheltered PIT Count is only required during odd-numbered years. Because of the cost and complexity involved, not all CoCs conduct an unsheltered count in even-numbered years. In 2024, all Oregon CoCs submitted sheltered PIT Count data. Only some conducted an …

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 …

Writing Back To Empire: Anticolonial Petitioning And Decolonisation In Postwar British West Africa, 1945–1960, Bright Alozie

Black Studies Faculty Publications and Presentations

This article reexamines petition writing as a strategic form of anticolonial resistance and negotiation in British West Africa between 1945 and 1960. Focusing on Nigeria and the Gold Coast (now Ghana), it argues that petitions – often regarded as apolitical or ineffective – were in fact deeply political texts through which colonised individuals asserted rights, challenged imperial authority, and participated in shaping decolonisation discourse. Drawing on new archival petitions, colonial correspondence, and administrative records, the study analyzes how a wide range of African actors – including trade unions, veterans, women’s organisations, and youth groups – appropriated colonial bureaucratic norms to …

Nuance As Praxis For Teaching About Mandated Reporting: Classroom Activities, Grace Pappas, Sam Harrell, Stéphanie Wahab

School of Social Work Faculty Publications and Presentations

As social work instructors, we have observed students increasingly wanting to engage in critical conversations about mandated reporting. Few resources are available to support instructors in facilitating these conversations. This teaching note offers content and lesson plans for exploring mandated reporting as a moral duty, a harm, an ethical dilemma, and a legal mandate in the classroom. Together, these pedagogical tools can help instructors embrace nuance as a practice for teaching about mandated reporting.

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 …

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, …

The Stochastic Occupation Kernel (Sock) Method For Learning Stochastic Differential Equations, M. L. Wells, Kamel Lahouel, Bruno Jedynak

Mathematics and Statistics Faculty Publications and Presentations

We present a novel kernel-based method for learning multivariate stochastic differential equations (SDEs). The method follows a two-step procedure: we first estimate the drift term function, then the (matrix-valued) diffusion function given the drift. Occupation kernels are integral functionals on a reproducing kernel Hilbert space (RKHS) that aggregate information over a trajectory. Our approach leverages vector-valued occupation kernels for estimating the drift component of the stochastic process. For diffusion estimation, we extend this framework by introducing operator-valued occupation kernels, enabling the estimation of an auxiliary matrix-valued function as a positive semi-definite operator, from which we readily derive the diffusion estimate. …

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 …

“I Have Nowhere To Go” : An Examination Of Post-Eviction Housing Outcomes Of Evicted Tenants, Alex Farrington, Natalie J. Cholula, Lisa K. Bates

Urban Studies and Planning Faculty Publications and Presentations

Given the extent of the eviction crisis in Oregon, it is crucial to investigate what happens to tenants after they are displaced from their homes. This report investigates three main questions concerning tenants’ post-eviction housing outcomes: Where do tenants live after they have been evicted? How do post-eviction housing outcomes affect tenants’ health, finances, and safety? How do rental assistance and legal assistance affect post-eviction housing outcomes?

Nearly two thirds of evicted tenants moved directly into some form of homelessness, including sheltered, unsheltered, or doubled-up homelessness. These findings indicate that Oregon’s eviction crisis and homelessness crisis are closely linked.

Tenants …
