Evaluating Nature-Based Versus Generic Physical Activity Programs To Address Chronic Health Conditions: Lessons From An Oregon (Usa) Pilot Study, Randall Bluffstone, Ma Chan, Cort Cox, Melinda M. Davis, Caitlin Dickinson, Sahan T. M. Dissanayake, Jeffrey D. Kline, Himani Ojha, Sterling Stokes, Srilakshmi Vedantam, Multiple Additional Authors

Economics Faculty Publications and Presentations

Evidence appears to be building that direct exposure to natural landscapes characterized by significant green cover, such as forests, can help to reduce chronic health conditions such as obesity, stress, hypertension, chronic cardiovascular conditions, depression, anxiety, cancer, and diabetes. One way to encourage greater exposure to nature may be through the use of nature prescriptions, whereby clinicians formally recommend (or prescribe) time in nature to their patients. Based on self-reported data, we describe the implementation and lessons learned from a pilot field experiment examining the clinical use of nature-based versus conventional exercise recommendations in rural Oregon. We discuss the potential …

Estimated Amounts Of Terrestrial Carbon Mobilized And Sequestered By The 1980 Mount St. Helens Eruption, Washington State, Usa, Lizzet G. Reyes

Dissertations and Theses

Volcanic eruptions significantly influence the geologic carbon cycle by emitting CO₂ and mobilizing terrestrial carbon pools. The 1980 Mount St. Helens (MSH) eruption offers a unique case study, triggering a massive landslide that displaced 2.7 km³ of sediment, buried 600 km² of forest, and disrupted regional carbon dynamics. Pre-eruption terrestrial carbon stocks, including aboveground biomass (AGB), dead biomass (D), and soil organic carbon (S), averaged 209.5 tC/ha. Post-eruption, total carbon density fell to 118.7 tC/ha, driven mainly by a 51% reduction in AGB, modest declines in D, and redistribution of S. Over 36 years, ecosystem recovery increased …

Do Gun-Purchase Waiting Periods Save Lives?, Grace E. Arnold, Mitchell Blaine Priestley

Economics Faculty Publications and Presentations

We study the impact of gun-purchase waiting periods on suicide rates using county-level mortality data from 1991-2019. We find that waiting periods are associated with a reduction in both firearm and overall suicide rates of approximately 5% and 2%, respectively. Novelly, we find that counties that are within 50 miles from a state without a waiting period experience no statistically significant reduction in suicides. Our findings reveal that the decrease in suicides under a waiting period is driven by counties that are more than 50 miles from a non-restricted neighboring state.

Development Scenarios And Wildfire Risk In Central Oregon, Samantha Hall

Dissertations and Theses

Risk from natural hazards occurs where areas vulnerable to natural hazards and development intersect. Development in vulnerable areas is a societal choice that has a lasting impact as our built environment is relatively permanent. Development patterns that contribute to increased wildfire risk mostly occur within the wildland urban interface, a land use type where development is at the fringes or intercept of wildland areas and is more flammable due to surrounding vegetation, slope, local climate, and other factors. To understand how past and future development potentials may impact fire risk in wildfire prone areas, a case study of Deschutes County, …

Introducing 'Society Work': The Professionalization And Localization Of Chinese Social Work In A New Era, Ke Cui, Timothy Sim, Chenxi Huang, Bowen Mcbeath

School of Social Work Faculty Publications and Presentations

This study focuses on current discussions around the newly-built Society Work Department in China. It argues that ‘society work’ helps to clarify the internationally recognized concept of ‘social work’ and this institutional reform promotes development of the social work profession and discipline, it also helps to decolonize social work in China.

The Effects Of School Safety Strategies On K-12 Schools: Armed Civilians, School Resource Officers, And Metal Detectors As Contributors To The School-To-Prison Pipeline, Rebeca Petean

Dissertations and Theses

In recent decades, K-12 public schools have introduced get-tough measures ostensibly to improve school safety through punitive responses to misconduct and delinquency--expanding from traditional security measures to more punitive, zero-tolerance policies and surveillance-based approaches. Academic literature and media accounts highlight that such efforts continue to proliferate and extend across our nation's school spaces. This three-paper dissertation examines how specific safety practices--namely, the presence of armed civilians, School Resource Officers (SROs), and random metal detector checks--influence student outcomes and contribute to the school-to-prison pipeline. Rooted in Becker's (1963) and Lemert's (1967) labeling theory, as well as Sampson and Laub's (1997) cumulative …

Geography Of Non-Daytime Work And Employer-Centered Transit Accessibility, Julia Mai Plotts

Dissertations and Theses

Non-daytime shift workers--including those on evening, night, rotating, and split shifts--face unique transportation challenges. Those who rely on public transit often contend with complicated commutes and longer wait times on public transit systems that have traditionally catered to the 9-to-5 workforce. Meanwhile, the non-daytime workforce is disproportionately composed of marginalized groups, including low-income workers, racial and ethnic minorities, and individuals with fewer education credentials. For many lower-income workers, car ownership does not present a viable alternative, as cost-of-ownership consumes a significant portion of their income. This makes access to nighttime public transit a critical equity concern. However, most transit accessibility …

Activity Levels Among Older Adults In A Life Plan Community, Emily D. Winters

OHSU-PSU School of Public Health Annual Conference

This study aimed to analyze resident's knowledge of the health and wellness programs available to them in their facility. It explored activity levels, preferred activity methods, and health and wellness program utilization among older adults residing in a life-plan community. A total of 166 survey respondents, aged 65 and older, were included in the analysis. Data were collected using a self-administered questionnaire designed to assess physical activity patterns, preferences for activity types, and engagement with the facility’s health and wellness offerings. Open-ended questions were assessed qualitatively through thematic analysis to find common themes within data. Results indicated that the most …

OHSU-PSU School of Public Health Annual Conference

Study Objective: This was a registry based retrospective observational cohort study of roughly 1,150 cardiac arrest cases transported by the Tualatin Valley Fire and Rescue emergency medical service (EMS) agency to hospitals in the Portland area from 2018-2019 and from 2022-2023 to compare cardiopulmonary resuscitation (CPR) ventilation policy changes between these two years from continuous chest compressions (CCC) to a compression ventilation ratio of 30:2. Hospital outcomes were linked to EMS records through trauma registries, state discharge and emergency department data. The primary outcome was survival to discharge, and the secondary outcome was positive neurological outcome (Cerebral performance category score …

Academyhealth - 2024 Data Visualization Winners, Chelsea Keating, Emily Boniface, Mina Colon

OHSU-PSU School of Public Health Annual Conference

Social determinants of health, such as income, employment, social contexts, and the built environment, influence the risk of food insecurity. Food insecurity can be defined as uncertain access to food and can lead to negative health outcomes like increased risk for obesity, chronic disease, and adverse effects on a child's development and mental health. Drivers like limited physical access to food, limited transportation options, and the quality and access to food assistance programs within local systems perpetuate health disparities—particularly in those communities with populations who have been systematically marginalized. This descriptive study uses 2022 data from the National Health Interview …

Exploring Health Equity With Culturally Specific Providers Of Permanent Supportive Housing, Judith R. Solomon

OHSU-PSU School of Public Health Annual Conference

Chronic homelessness is an important public health issue. Permanent Supportive Housing (PSH) is a promising opportunity for transitioning people experiencing homelessness into housing, however there remain unaddressed racial inequities in service provision and outcomes. The aim of this study is to better understand the role of culturally specific (CS) providers of PSH in improving health equity. I analyzed interviews with CS PSH providers for themes related to health and healthcare. Providers spoke about the importance of connecting clients to healthcare. Providers stressed the importance of honesty and lived experience, highlighting the strong sense of responsibility to the community. Providers also …

Comparing Acuity Of Patient Care At Student Run Free Medical Clinic Locations, Hana Warmflash, Olivia Krol, Alex Foster

OHSU-PSU School of Public Health Annual Conference

Intro:

Student run free medical clinics (SRFC) are present at roughly 75% of Association of American Medical Colleges member institutions1,2 providing care for underserved populations, such as those experiencing houselessness. 3 Persons experiencing houselessness have a higher burden of illness than housed persons but experience a greater barrier to obtaining care4. Delays in care result in more complex and longer hospitals stays4,5.

Our SRFC, Bridges Collaborative Care Clinic (BCCC), functions to address emergent complaints and monitor chronic health conditions. We aim to demonstrate how relocating from River District Navigation Center (RDNC) to a more accessible location, Resource Center (RC), enabled …

Primary Health Care: Strengthening Health Systems In Low- And Middle-Income Countries, Erin Young

OHSU-PSU School of Public Health Annual Conference

In recent decades, global health priorities have shifted away from promoting selective, donor-led interventions and towards the goal of strengthening primary health care systems in low- and middle-income countries. This project seeks to identify recommendations for and best practices of primary health care system development from the existing literature. A critical literature review was conducted using the Ovid-MEDLINE database to identify articles that focused on primary health care, included recommendations for health systems strengthening, and addressed low- and middle-income countries. Ultimately, 27 articles published between 2004 and 2019 were included in this review. Results suggest that important priorities for building …

How To Kill A Human: Creating An Immersive Learning Game, Théo Caldwell, Nathan Bonnell

OHSU-PSU School of Public Health Annual Conference

How to Kill a Human is an experiment in teaching through gameplay. The environmental crisis facing the planet, though denied by many, is a collection of well-documented historical environmental catastrophes. The purpose of this project was to design a method of relating the impacts of environmental systems on human health, highlighting the dangers of ill planned human tampering, by presenting hypothetical environmental catastrophes and then relating them to documented historical disasters. In pursuit of this goal, we designed a semi-collaborative game for three to six players with a suggested age rating of 10+, ideal for teaching individuals of middle school …

Differences Between Stem Students And Faculty On Seeing Value In A Classroom Belonging Exercise, Kaisa S. Holt

OHSU-PSU School of Public Health Annual Conference

Efforts to enhance belonging in undergraduate STEM classrooms are believed pivotal for student success. However, we must not only promote belonging interventions but also understand STEM students and faculty perceptions of their value and utility. We gathered perspectives of faculty and undergraduates regarding the implementation and efficacy of a belonging exercise (Our Lives Lived, OLL) used in multiple STEM classes at one university over two years. We hypothesized that students would see more value in the exercise than faculty. We sent a survey instrument with an OLL summary and a series of open-ended responses to faculty. We recruited for focus …

Universal Health Care, Oregon, Jennifer S. Arnold, Bethany Clouse, Alec Martin

OHSU-PSU School of Public Health Annual Conference

Historically, the US has chosen not to fund universal health care at every opportunity, leaving our nation as the only industrialized country without some system of health coverage for our citizens and with the worst health care outcomes of any high-income nation in the world. Health care in Oregon is no exception. Our current health care system is financially unsustainable, harmfully complex, and socially unjust, as well as inequitably delivered. Too many Oregonians, because of their race, age, income, geography, or insurance, endure vastly different health care access, varied health care quality, and wide-ranging health outcomes. In 2019, the Oregon …

Behind The Walls: The Implications Of Assisted Living Building Codes On Resident Safety, Adam Pennavaria, Lindsey Smith, Paula Carder, Cassandra Hua, Eric Jutkowitz, Kali Thomas

OHSU-PSU School of Public Health Annual Conference

As the US population collectively ages, issues related to assisted living (AL) resident safety have become an increasingly pressing issue for the general public, reflected by major media reporting in the last year. The building codes that govern ALs play an important role in mitigating the risks associated with falls, wandering, and other hazards, especially for residents living with Alzheimer’s disease and related dementias. We sought to understand how states vary in their approaches to building code regulations that might impact resident safety. We used search term-based text retrieval to identify areas of text relevant to locks, alarms, and egress …

The Intersecting Association Of Speaking A Non-Dominant Language And Lower Healthcare Access On Self-Reported Depression Among U.S. Adults: A Cross Sectional Study Using Nhanes Data (2015-March 2020), Vincenzo J. Cornacchione, Corey Linver

OHSU-PSU School of Public Health Annual Conference

Objective: This analytic study examined the joint and independent associations between language preferences and healthcare access on moderate to severe depression among non-institutionalized adults living in the U.S., using data from the 2015 to March 2020 National Health and Nutrition Examination Survey (NHANES).

Methods: In this cross-sectional study design, we analyzed a nationally representative data set comprised of 11,051 participants. Multivariable logistic regression models were used to estimate the joint and independent associations between our dual exposures and moderate to severe depression, adjusting for key demographic variables based on our theoretical framework. We created categorical measures of preferred language (speaking …

Primary Place To Go For Health Care And Its Association With Hpv Prevalence In Us Adults: Results From Nhanes 2013-2016, Amy L. Mcveety, Miyuki Sun

OHSU-PSU School of Public Health Annual Conference

Background: While access to health care is a known risk factor for many infectious diseases, including sexually transmitted infections, little research has investigated the relationship between access to primary care services and prevalent human papillomavirus (HPV) infection. Given HPV’s prevalence in the general population and lack of available treatments, it is necessary to understand possible risk factors to identify areas for intervention. This study uses primary place to go for health services as a proxy measure for access to care, in order to understand which sources of health care are serving patients with the highest prevalence of HPV infections and …

Association Between Arsenic And Other Heavy Metal Exposures Through Drinking Water And Food With Lung Function And Respiratory Symptoms: A Cross-Sectional Study, Sofia I. Chapela Lara, Seth O'Neal Md, Mph For The Cysticercosis Working Group In Peru

OHSU-PSU School of Public Health Annual Conference

Impaired lung function is a major health concern, particularly in children, as it increases the risk of chronic respiratory diseases and long-term morbidity. Environmental exposure to heavy metals (HMs) such as arsenic, lead, cadmium, and manganese has been associated with reduced lung function and respiratory symptoms. However, findings vary by exposure context and population, with limited research in pediatric populations and few studies evaluating the combined effects of multiple HMs. These exposures disproportionally affect marginalized rural communities, especially in low and middle-income countries with mining activities. This cross-sectional study investigated the association between exposure to As and other HMs through …

Deidentified patient data from medical clinics from January 2024 to February 2025 were analyzed using RStudio …

Effects Of Wetting Events On Mass Timber Surface Microbial Communities And Voc Emissions: Implications For Building Operation And Occupant Well-Being, Gwynne Á. Mhuireach, Susan Collins, Leslie Dietz, Patrick Finn Horve, Aurélie Laguerre, Dale Northcutt, Jason Stenson, Kevin Van Den Wymelenberg, Elliott Gall, Mark Fretz

Mechanical and Materials Engineering Faculty Publications and Presentations

IntroductionHumans have used wood as a construction material throughout history. Currently, mass timber products, such as cross-laminated timber (CLT), are becoming more popular as a structural material, since they are renewable and have a lower carbon footprint than concrete or steel. Nonetheless, some building types, such as healthcare, veterinary, and food manufacturing, avoid using structural mass timber due to concerns about microbial growth in the event of wetting. One solution is to use protective coatings on mass timber products to increase moisture resistance, although the coatings themselves may generate concerns about volatile organic compound (VOC) emissions. Natural uncoated wood also …

Addressing The Promise And Peril Of Ai For Nonprofit Management Through A Data Feminist Pedagogy, Billie Sandberg, Rafeel Wasif, Laura C. Hand

Public Administration Faculty Publications and Presentations

The use of artificial intelligence (AI) has opened up possibilities for nonprofit management, and practitioners are taking notice. A recent study revealed that nearly 90% of nonprofit organizations are interested in using AI (MacDonald, Citation2023). Another study indicated that more than half of the nonprofits surveyed use AI to support finance, human resources, communications, and mission-related (i.e., working with clients, program implementation, and grantmaking) functions (Herschander, Citation2024). Indeed, many of us likely know student-practitioners and nonprofit colleagues who leverage AI to help write donor thank-you notes, newsletters, grant proposals, and press releases and who work for nonprofits that incorporate chatbots …

Perceptions About Potential Microplastic Interventions: A Study On Knowledge, Concerns, And Willingness To Pay, Amanda Gannon, Elise F. Granek, Max Nielsen-Pincus, Luke Harkins

Environmental Science and Management Faculty Publications and Presentations

Among emerging contaminants, microplastics (MPs) are of particular concern due to their ubiquity across environments and the unique challenges posed by attempted removal. In-line washing machine filters are one potential tool for preemptively preventing a category of MPs from entering waterways. A sample of registered voters and environmental interest groups in Oregon were asked about their general knowledge and concerns surrounding microplastics, as well as their willingness to pay for high-efficiency washing machine filters. Findings show that less than a quarter of all respondents would be willing to pay full price for a high-efficiency filter, indicating a limited-scale early adopter …

An Effective Genetic Algorithm For Mixed Precision, Wanyu Zhang, Yu Shang, Min Tsao, Yiwei Li, Xiaoyu Song

Electrical and Computer Engineering Faculty Publications and Presentations

The precision of floating-point numbers is a critical task in high-performance computing. Many scientific applications rely on floating-point arithmetic, but excessive precision can lead to unnecessary computational overhead. Reducing precision may introduce unacceptable errors. Addressing this trade-off is essential for optimizing performance while ensuring numerical accuracy. In this paper, we present a genetic algorithm-based approach for tuning the precision of floating-point computations. Our method leverages algorithmic differentiation and first-order Taylor series approximation to assess the impact of precision variations efficiently. We employ stochastic partitioning algorithms with multiple precision combinations that meet the error requirements. Moreover, we present a genetic heuristic …

Acompañamiento And Assessment: Examples Of Community Building Through Assignments In A First-Year Class, Shaianne Tran, Hector Amezola, Dalissa Rodriguez, Morgan Baird, Jennifer Fuentes Luna, Alejandra Vazquez, Fattemah Zia, David Peterson Del Mar

Amplify: A Journal of Writing-as-Activism

This collection of seven diverse assignments written by students from under-represented communities for a first-year inquiry class on immigration, migration, and belonging illustrates how instructors can facilitate a sense of belonging or acompañamiento through course assignments, assessment instruments. Each of the student authors provides a retrospective introduction on how their personal reflection, essay, or research project helped them to make personal connections within or outside of the class. The instructor provides a brief introduction to the concept of acompañamiento and why it is particularly important for New Majority college students.
