Automatic Measurement Of Dialogue Engagingness In Multilingual Settings, Amila Ferron

Dissertations and Theses

Expansive use of large language models (LLMs) as dialogue systems brings increased importance to the evaluation of the responses they generate. Although evaluation of qualities such as coherence and fluency are readily possible with well-established automatic metrics, engagingness is often measured with human evaluation -- a process that can be costly and slows the pace of development. Existing automatic metrics for engagingness have low to moderate correlation with human annotations, evaluate the response without the conversation history, are complicated to implement, or are designed for a specific dataset. Moreover, they have been tested exclusively on English conversations. Given that dialogue …

Towards A New Discourse On Success In Alternative Education, Samuel Thomas Settelmeyer

Dissertations and Theses

Although researchers agree that Alternative Education (AE) within the United States is an essential set of schools and programs that do things beyond traditional education, they do not agree on the purpose for these efforts. To understand how researchers can connect between existing perspectives and consider new ways that they can discuss success in the future, I interviewed 16 students and 15 staff from three different AE schools within the same state. Through thematic analysis, I found students and staff to describe success as an amalgamation of individual and common conceptions, requiring individual effort and support, a commitment to daily …

Estimating Combined Effects Of Climate Change And Land Cover Change On Water Regulation Services Of Urban Wetlands In Valdivia, Chile, Jason Sauer, N. B. Grimm, Olga Barbosa, Elizabeth M. Cook, A. Mustafa, K. Kunkel, T. Mcphearson, A. Ballinger

Geography Faculty Publications and Presentations

The relationship between cities and wetland cover varies across the globe, with some cities converting wetlands to low‐ and high‐density urban cover and others preserving, conserving, or restoring wetlands, or constructing new ones. However, the scientific literature lacks studies relating changes in systemic flood risk in an urban stormwater management systems to changes in wetland cover. Furthermore, whether and how such relationships are affected by changing storm intensity under climate change is unknown. We present a case study on the effects of changes in urban wetland extent and storm intensity on flooding in an urban drainage system in Valdivia, Chile, …

Primary Care In The University Setting After Covid-19: A Multiple Case Study Of Student Health Services In Oregon, D. Chad Johnson

Dissertations and Theses

In 2020, the COVID-19 pandemic disrupted operations across the settings of primary care and higher education institutions (HEI). HEIs faced sudden decreases in revenue because of reduced enrollments and external pressures to rapidly adapt delivery methods to accommodate the inability to provide in-person classes. Similarly, most primary care settings experienced major reductions to in-person visits and fee-for-service revenues. Student health services (SHS) exist within both primary care and higher education settings and are a unique and poorly understood aspect of primary care. This research set out to explore this under-studied primary care setting by answering the question: "How has COVID-19 …

Experiences Of Community College Stem Students In Transferring And Adapting To A Four-Year Urban University, Mackenzie Jade Gray

Dissertations and Theses

Ensuring that the bachelor's degree pathway that begins at a community college is a robust option for science, technology, engineering, and mathematics (STEM) students will be key for addressing the calls to increase and diversify the future STEM workforce.

In this work, we aim to understand the experiences of community college students as they transfer, adapt, and persist to graduation at an urban four-year university.

First, we used the Model for Analyzing Human Adaptation to Transition to explore the experiences of community college STEM students …

Nostalgia Marketing: An Integrative Framework, Yasamin Mehdian Rad

University Honors Theses

Nostalgia is a longstanding yet evolving concept in marketing, employed to evoke sentimental longing for the past. It is a complex emotion that can invoke warmth, happiness, sadness, and melancholy, and can be directed towards both personal memories and imaginative pasts--times and places that one has never experienced. This dual nature of nostalgia, categorized into personal and imaginative nostalgia, offers a powerful emotional appeal that marketers leverage to influence consumer behavior. Since the 1950s, the use of nostalgia in marketing has increased significantly, allowing brands to forge deep emotional connections with consumers. Despite its prevalent use, research on nostalgia's impact …

A Systems Theoretic View Of Speculative Realism, Martin Zwick

Complex Systems Faculty Publications and Presentations

Recent developments in Continental philosophy have included the emergence of a school of “speculative realism,” which rejects the human-centered orientation that has long dominated Continental thought. Proponents of speculative realism differ on several issues, but many agree on the need for an object-oriented ontology. Some speculative realists identify realism with materialism, while others accord equal reality to objects that are non-material, even fictional. Several thinkers retain a focus on difference, a well-established theme in Continental thought. This paper looks at speculative realism from the perspective of systems theory. Many of the tenets of speculative realism have long been features of …

Training Social Work Master's Students For Integrated Health Care Settings: The Importance Of Specialized Education, Passion Ilea, Ericka L. Kimball

School of Social Work Faculty Publications and Presentations

Integrated health care poses a unique opportunity for social workers to deliver person-centered, empowering, and collaborative care addressing all aspects of patient health. This study analyzed four years of data from a project designed to train social work master’s students to be effective members on integrated teams. Students that participated in the project achieved statistically significant levels of improvement from pre- to posttests with large effect sizes on the Behavioral Health Consultant Core Competency Tool skills (n = 93, Cohen’s d = -1.752, t(92) = -16.894, p < .001) and the Team Skills Scale (n = 94, Cohen’s d = -1.558, t(93) = -15.101, p < .001). Wilcoxon signed-rank tests confirmed improvements. No existing evaluations of integrated training for social work students capture behavioral health competencies data. Offering specialized training in integrated behavioral health work to students has immense potential benefit for outgoing social workers seeking to support patients.

Examining The Effects Of Emotional Support And Therapy Animals On Anxiety And Depression In University Students: A Literature Review, Alexys Endries

University Honors Theses

University students are an especially vulnerable population to anxiety and depression. Simultaneously, they have little access to mental health resources, but emotional support and therapy animals may provide a feasible solution. This literature review explored the ways in which emotional support and therapy animals may be of help to young adults in higher education settings. Specifically, this collection of research aimed to contour the benefits that come with the applied use of emotional support animals (ESAs) and animal-assisted therapy (AAT) as mental health interventions, and how they set themselves apart from alternative treatment options. This synthesis of the evidence found …

Within the United States, Indigenous communities are especially at risk of victimization in relation to a history of systemic violence and consequent neglect. Therefore, the need for culturally competent care is crucial. This study seeks to address how culturally sensitive approaches to trauma-informed care can be developed and implemented by various providers to effectively support Native American victims of human trafficking in accessing assistance services. In order to evaluate the problem, a literature review was conducted, paired with qualitative interviews from relevant stakeholders. The findings demonstrated a significant …

A Review Of The Toxicity Of Ingredients In E-Cigarettes, Including Those Ingredients Having The Fda's "Generally Recognized As Safe (Gras)" Regulatory Status For Use In Food., Nada O F Kassem, Robert M. Strongin, Andrea M. Stroup, Marielle C. Brinkman, Ahmad El-Hellani, Hanno C. Erythropel, Arash Etemadi, Vernat Exil, David H. Peyton, Multiple Additional Authors

Chemistry Faculty Publications and Presentations

Some firms and marketers of electronic cigarettes (e-cigarettes; a type of electronic nicotine delivery system (ENDS)) and refill liquids (e-liquids) have made claims about the safety of ingredients used in their products based on the term "GRAS or Generally Recognized As Safe" (GRAS). However, GRAS is a provision within the definition of a food additive under section 201(s) (21 U.S.C. 321(s)) of the U.S. Federal Food Drug and Cosmetic Act (FD&C Act). Food additives and GRAS substances are by the FD&C Act definition intended for use in food, thus safety is based on oral consumption; the term GRAS cannot serve …

Valid Confidence Intervals For Μ,Σ When There Is Only One Observation Available, Anirban Dasgupta, Stephen Portnoy

Mathematics and Statistics Faculty Publications and Presentations

Portnoy (2019) considered the problem of constructing an optimal confidence interval for the mean based on a single observation X ∼ N(µ, σ2). Here we extend this result to obtaining 1-sample confidence intervals for σ and to cases of symmetric unimodal distributions and of distributions with compact support. Finally, we extend the multivariate result in Portnoy (2019) to allow a sample of size m from a multivariate normal distribution where m may be less than the dimension.

The ANN model (comprising five nodes in one hidden layer), which was constructed and trained using 60 data points, yielded an R² value of 0.94 and a mean average percent error …

Oregon In Motion: Shaping Communities Through State Transportation Legislation, Cassie Wilson

PSU Transportation Seminars

About every eight years, the Oregon state legislature passes a large state transportation funding package. Transportation funding packages in Oregon have historically included funding mechanisms such as the gas tax, program areas such as Safe Routes to School, projects such as freeway widenings, and transparency and accountability measures such as establishing new reporting requirements and advisory committees. The way this legislation is developed and who has a seat at the table highly influences package contents and the public and political support needed for its passage. In this presentation, I will provide highlights from my recently published report, Oregon in Motion …

Feeling Otherwise: A Hermeneutic Phenomenological Study Of Queer And Trans Youth Of Color Who Create And Embody Fursonas, Hazel Ali Zaman

Dissertations and Theses

Queer and trans youth of color are often the target of surveillance, bullying, discrimination, and abuse. However, in an attempt to navigate such violent and discriminatory circumstances, the queer and trans youth of color in this dissertation found refuge in furry art and performances, both online and offline, where they were able to express themselves freely and thus acquire a sense of belonging among others with similar experiences. In this dissertation, "a furry" is used to refer to an individual who self-identifies as one who has an affinity for anthropomorphic animal characters. A common practice among furries is creating a …

Our Body-Minds Are Not Apologies: How Systemic Oppression, Beauty Standards & Desirability Politics Impact The Body-Image & Sex Lives Of Trans & Non-Binary People With Physical (Dis)Abilities, Elm Mack

University Honors Theses

Due to the ableism, whiteness, and cisgender-heteropatriarchy in the US, people who are marked by racial, physical, neuro, and gendered differences are stereotypically considered to be less desirable. By applying a perspective informed by Disability Studies, Trans Studies, and Queer of Color Theory (including scholars like Eli Clare, Robert McRuer, Sonya Renee Taylor, Audre Lorde, Sami Schalk, Chris Finley, and Alicia Cox), I investigate how societal norms, beauty standards, and systemic oppression have disproportionately impacted the body-images and sex lives of trans and non-binary people with physical (dis)abilities. This thesis aims to shed light on the variety of ways in …

Design And Test Of Asynchronous Systems Using The Link And Joint Model, Ebelechukwu Esimai

Dissertations and Theses

Asynchronous circuits offer numerous advantages, including low energy consumption and good composability and scalability. However, they remain meagerly adopted in the mainstream semiconductor industry. One reason is the limited number of design tools available to help designers navigate design complexity, particularly the myriad of asynchronous implementation styles.

This dissertation focuses on managing the myriad of asynchronous implementation styles by utilizing a circuit-neutral model, called Links and Joints, and embedding this Link-Joint approach into a design flow. Although years of past work have already laid the groundwork, the work in this dissertation identifies and addresses key missing pieces.

First, the …

Redesigning Secure School Entry Thresholds To Create Inclusive And Welcoming Environments, Alex Yarovaya

University Honors Theses

Schools are known to have been one of the largest assets to communities, providing folks with integral resources and accessible spaces that can foster a variety of activities. Over the last decade, however, our perspective of schools has undergone significant changes. Schools have eagerly been undergoing the process of "hardening" by implementing safety and violence prevention tactics with Crime Prevention Through Environmental Design (CPTED) as a response to the staggering increase of gun violence incidents and safety & security issues today. Schools have been scrambling to accommodate this change in reality by retrofitting with security systems, implementing high security measures …

Social Justice In Social Work: A Critical Discourse Analysis, Erica Fonseca

Dissertations and Theses

Social justice is central to social work and guides the profession's ethics, educational standards, and practices. It is aspirational and actionable, ideological and practical, and is simultaneously shaped by, and shapes in turn, social work. Consequently, this study understands social justice to be a discourse. Despite its ubiquity throughout the profession, what constitutes social justice, how it should (or could) be practiced, and what epistemologies orient social work to the concept continue to be debated. Given social work's express promotion of social justice and the myriad ideas and practices that follow from this critical value, the concept and the foundational …

Some of the more extensive VHA facilities offer advanced health care services, such as organ transplants and plastic …

The Exploration Of Latino Bip Participants' Experiences Of Oppression And Expressions Of Critical Consciousness, Adrian Luis Manriquez

Dissertations and Theses

According to Freire (1970), individuals and groups who are systemically oppressed in society often develop and struggle with a sense of internalized oppression, and those who fail to address their own oppression will likely engage in the oppression of others. Conceivably, this is the state of affairs for Latino males who perpetrate intimate partner violence (IPV). However, Latinos who use IPV behaviors are often viewed solely as "villains" or oppressors (Corvo & Johnson, 2003), omitting the various contexts in which this subgroup of males might be subjected to oppressive conditions outside of their intimate relationships. This contributes to an absence …

Contested Places: A Typology For Responding To Place-Based Harms, Amie Thurber, Amy Krings, Mónica Gutiérrrez, Jason Sawyer, Greer A. Hamilton

School of Social Work Faculty Publications and Presentations

In response to historic and ongoing devaluation of certain people, and concurrently, the places they live, many communities are grappling with how to respond to place-based harms. This has produced a wide range of responses, such as calls for “Land Back,” reparations programs, arts-based neighborhood regeneration, and local history initiatives. This paper explores the potential roles community practitioners can play in these contested places. Drawing on a review of the literature, this paper offers an emerging typology for responding to place-based harms.

Living On The Outskirts Of Things: Women And Nonbinary People Of Color With Cognitive Disabilities Describe Their Employment Experiences, Laura Spura Rodriguez

Dissertations and Theses

This study examines the experiences of discrimination and the strategies used to navigate employment for women of color and nonbinary people of color (POC) with cognitive disabilities (CD) through their own narratives. Using Dis/ability Critical Race Theory and an interpretive description methodology, this study engaged 10 women of color and/or nonbinary POC with CD in semi-structured interviews in order to answer the following research questions: 1) What stories do women of color and nonbinary POC with CD tell about their experiences seeking employment? 2) What are the narratives of women and nonbinary POC with CD about their experiences of racism, …

Geographies Of Entitled Anger: Revanchist Populism In Brazil And Beyond, Ryan Centner, Mara Nogueira

Urban Studies and Planning Faculty Publications and Presentations

In an age of resurgent populism, emotional geographies play an underexamined yet pivotal role in explaining cross-class alliances that have enabled particularly angry forms of revanchist politics across world regions. This essay delineates the notion of “revanchist populism” and its grounding in “entitled anger,” as well as self-righteous geographical imaginations more broadly, to shed new light on the Brazilian case in recent years, which is further explored in this special issue. Beyond Brazil, we suggest how this approach can be used to bring a more geographical perspective to related iterations of revanchist populism elsewhere in the world and across the …

Wilkins, Eric Hurwitz, Jessica Y. Islam, Dongmei Li, Jing Sun, Sandra E. Safo, Jennifer M. Ross, Cara D. Varley, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Abstract Background: Leveraging the National COVID-19 Cohort Collaborative (N3C), a nationally sampled electronic health records repository, we explored associations between individual-level social determinants of health (SDoH) and COVID-19-related hospitalizations among racialized minority people with human immunodeficiency virus (HIV) (PWH), who have been historically adversely affected by SDoH. Methods: We retrospectively studied PWH and people without HIV (PWoH) using N3C data from January 2020 to November 2023. We evaluated SDoH variables across three domains in the Healthy People 2030 framework: (1) healthcare access, (2) economic stability, and (3) social cohesion with our primary outcome, COVID-19-related hospitalization. We conducted hierarchically nested additive …

The Women Of The Oregon State Insane Asylum: 1900-1910, Rebekah Catherine Averette

Dissertations and Theses

This thesis explores the lives of female patients at the Oregon State Insane Asylum between 1900 and 1910 and examines the significance of that decade as a period of transition in asylum care from a moral treatment model to a focus on moral hygiene practices to subvert insanity before it took root and medicalized psychiatric treatment for severe or chronic cases requiring institutionalization.

At the turn of the twentieth century, state insane asylums were in the aspirational early stages of transforming into specialized psychiatric and medical hospitals. Ultimately, the hoped-for transformation would not materialize in a meaningful way until well …
