Under The Influence Of Parents: A Longitudinal Study Of Children’S Walking, Kyu Ri Kim, Jennifer Dill

Student Research Symposium

Researchers have studied children's active travel; however, they have mostly been cross-sectional studies dealing with commuting to school and parental attitudes. To find ways to promote children's active travel, this longitudinal study uses panel data (two time periods) to examine how parents' actual walking and safety perception correlated with children’s walking. Using data from 240 children aged 4-16 and their parents in Portland, Oregon, we estimated a cross-lagged panel model (CLPM) to analyze the continuous relationships. We found that parents with more positive attitudes toward their walking walked more, and their children also walked more in both periods. In addition, …

This research demonstrates the efficacy of this existing working model, which could be similarly implemented in Portland with some adjustments. Portland has the Portland …

Power & Planning: A Critical Comparison Of Tribal And Non-Tribal Wildfire Protection Plans, Christian J. Heisler

Student Research Symposium

In 2003, the US government passed the Healthy Forest Restoration Act, which urged wildfire-prone communities to develop Community Wildfire Protection Plans (CWPPs). These plans allow local groups to contextualize risk, practice social learning, and develop social capital while addressing wildfire risk. Within planning realms, however, decision-making power is usually concentrated unequally between social groups which can limit the influence of marginalized communities. Tribal nations, specifically, have been excluded from wildfire planning since European contact, signaling that CWPPs may not reflect Indigenous worldviews and priorities. Given the recent push from the federal government to increase land management collaboration with tribes, it …

Inequities In Chronic Stress Exposure At The Intersection Of Race, Gender, And Sexual Identity In A Nationally Representative Sample Of Us Adults, Jordan M. Lancaster, Efrain H. Chavez Martinez

OHSU-PSU School of Public Health Annual Conference

Background

Social inequity rooted in systemic oppression is robustly associated with mental and physical health; chronic stress is highlighted as a key mechanism. Limited research examining the association between sexual identity alone and C-reactive protein (CRP) – an upstream biological marker of chronic stress exposure – has yielded mixed results.

Purpose

To examine whether race/ethnicity, gender, and sexual identity interact to produce unequal levels of CRP.

Methods

Using cross-sectional data from the 2003-2010 waves of the National Health and Nutrition Examination Survey, we examined intersectional (self-reported race*gender*sexual identity) patterns in log-transformed CRP levels using a multivariable linear model among 10,885 …

Intersectionalities Of Systematic Barriers Set Upon Underrepresented Students In Stem: Capturing The Potential Benefits Of Online Modality, Raiyasha Aiyanna Paris

University Honors Theses

The prevalence of racism and microaggressions in STEM disciplines within colleges presents significant hurdles to the academic success and well-being of underrepresented students. Microaggressions, encompassing subtle biases and stereotyping, have a cumulative impact, inducing heightened stress, diminished motivation, and reduced self-efficacy among minority students, thereby impeding cognitive functioning and hindering academic progress (Ogunyemi et al., 2020). The existence of these negative emotional responses creates a less conducive learning environment for academic achievement. Additionally, structural inequalities within STEM institutions contribute to disparities in resource access, limited mentorship opportunities, and support networks crucial for success in STEM fields (Atkins et al., 2020). …

A Survey Of North American Electric Bicycle Owners, Cameron Steven Bennett

Dissertations and Theses

Rapid recent growth in the popularity of electric bicycles (e-bikes) has captured the attention of transportation researchers and policymakers seeking safe, sustainable, and active alternatives to conventional transportation modes. This thesis presents an investigation of e-bike owners in North America, complementing previous efforts in 2013 and 2017, and suggests implications for North American transportation planning.

An online survey was distributed to e-bike owners in the United States and Canada through email outreach, purchase incentive programs, and social media. The survey included questions on the respondents’ demographics, e-bikes, purchase decisions, travel behavior, perceptions of e-bikes, crash experience, maintenance needs, and receipt …

Latine Dual Language Bilingual Education Teachers' Work Experiences, Nelly Noemi Patiño Cabrera

Dissertations and Theses

Given the increasing concern about the scarcity of Dual Language Bilingual Education (DLBE) teachers, it is crucial to understand the trends in teacher retention and attrition from the perspective of DLBE teachers themselves. DLBE teachers departing from their jobs imposes a significant burden on schools and students and affects the implementation of DLBE programs. To delve into this issue, this critical qualitative study focused on the work experiences of Latine K-5 Spanish/English DLBE teachers. Specifically, this study involved six participants divided into two groups of DLBE teachers in the teaching trajectory: three Latine K-5 Spanish/English DLBE teachers currently teaching in …

Data From: Active Transportation Counts From Existing On-Street Signal And Detection Infrastructure, Sirisha Kothuri, Patrick Allen Singleton, Mahyar Vahedi Saheli, Elizabeth Yates, Joseph P. Broach

Civil and Environmental Engineering Faculty Datasets

This study’s objective was to use data from existing traffic signal infrastructure to estimate pedestrian volumes. Pedestrian push-button actuations were collected from signal controller logs at 49 intersections in western Oregon and an additional 16 intersections in eastern Oregon. These actuations were then compared to observed pedestrian counts, totaling over 34,000 people, obtained from video recordings. After exploring various options, a simple quadratic relationship was modeled using a single measure of pedestrian signal activity: the number of push-button presses (filtered to remove multiple presses within 15 seconds). The model’s predictions showed a correlation of 0.86 with observed pedestrian volumes and …

What Drives Housing Choices Of Refugees And Immigrants?, Diane Mitschke, Anne Nordberg, Stephen Mattingly, Katherine Kitchens, Yasmin Al-Zubi, Farah Naz

TREC Project Briefs

When newcomers to the US initially settle, if their chosen location does not meet their expectations or needs, that often propels them to relocate. To determine what helps drive those transition decisions, the researchers interviewed people if they fulfilled one of these requirements:

• They were members of the Dallas County community who were planning to move in the next five years.

• They had recently (within the past five years) moved from their initial residence following their arrival in Dallas County.
• They also had to be immigrants to or refugees in the US who were at least eighteen years old. Out …

Housing Choice, Transportation Equity, And Access To Opportunities In Refugee And Immigrant Communities, Diane Mitschke, Anne Nordberg, Stephen Mattingly, Katherine Kitchens

TREC Final Reports

Mobility directly impacts access to opportunities for all protected classes; however, transportation planning and public transit agencies and housing authorities rarely coordinate affordable housing and the transportation system planning decisions. This lack of coordination often leads to mismatches between access to opportunities and affordable housing. Safe access to employment, quality schools, and healthcare represent a few of the many factors that may influence housing choice. For most households with budget constraints, all of these factors may not be achievable. While existing research documents the mismatch between affordable housing and access to opportunities, the role that mobility plays in residential selection …

App-Based Data Collection To Characterize Latent Transportation Demand Within Marginalized And Underserved Populations, Noelle L. Fields, Courtney Cronley, Stephen Mattingly, Nicole Iroz-Elardo, David Levine, Nithisha Gudipati, Cristine Highfill, Mary Kris Stringfelllow, Anna O'Dell, Rebecca Cole, Melody Huslage

TREC Final Reports

Our interdisciplinary team refined an app prototype, MyAmble, to gather data related to quantity of transportation disadvantage and latent demand, and to identify psycho-social-economic corollaries. MyAmble utilizes a traditional travel diary format but expands the type of trips measured to include 1) completed trips, 2) missed trips, and 3) latent travel demand. The app also measures the real-time perceived impact of transportation behaviors (realized and latent) on participants’ physical health, mental health, social engagement, and employment/academics. Finally, the app has a text-messaging feature, Travel Buddy, that is used to increase participant engagement and retention over longitudinal data collection. The project …

The County of Hawai'i, has charted a unique course through the establishment of Action Committees which serve as an intermediary to uplift grassroots implementation efforts while remaining closely entwined with County resources and processes. This interplay provides a unique case study that results in somewhat of an "identity crisis": Action Committees do not have the autonomy of external …

Key Points In Preparation For Oregon Legislative Session (2024): Examining The Multifaceted Impacts Of Drug Decriminalization On Public Safety, Law Enforcement, And Prosecutorial Discretion, Kelsey S. Henderson, Christopher Campbell, Brian Renauer

Criminology and Criminal Justice Faculty Publications and Presentations

These findings are part of a 3-year study to examine the impacts of possession of PCS law changes on: (1) law enforcement discretion, (2) prosecutorial decision-making, (3) courts/sentencing, and (4) public safety. The key findings, unless noted, represent statewide trends and impacts. Prior to M110, other statewide changes in policy, law, and historical events such as the COVID-19 lockdown/court backlog and public defense crisis also had important impacts on enforcement, prosecution/sentencing, and public safety outcomes. As such, data collected during the early implementation of M110 is not likely a reliable predictor of its ultimate impact. The data reported on below …

Economic Analysis Of Population-Based Next Generation Sequencing For Breast Cancer, Sapphire Curelaru

University Honors Theses

Breast cancer develops due to accumulated DNA replication insults which causes cancer to uncontrollably proliferate. An individual's predisposition to developing cancer, as well as the composition of a tumor, can be sequenced using genetic tests. Myriad's BRACAnalysis CDx^® seems to be the most utilized genetic test. However, Next Generation Sequencing (NGS) seems to be a better genetic test for breast cancer when compared to Myriad's BRACAnalysisCDx^® in terms of return-time, accuracy, efficiency, and healthcare cost. By using Next Generation Sequencing tests, stakeholders can save money on genetic testing which can be invested in more genetic tests. Payers can …

A Guaranteed Income Intervention To Improve The Health And Financial Well-Being Of Low-Income Black Emerging Adults: Study Protocol For The Black Economic Equity Movement Randomized Controlled Crossover Trial, Sheri A. Lippman, Margaret Libby, Michelle K. Nakphong, Abigail Arons, Monica Balanoff, Rain Mocello, Emily A. Arnold, Starley B. Shade, Marguerita Lightfoot, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background

Economic inequity systematically affects Black emerging adults (BEA), aged 18–24, and their healthy trajectory into adulthood. Guaranteed income (GI)–temporary, unconditional cash payments–is gaining traction as a policy solution to address the inequitable distribution of resources sewn by decades of structural racism and disinvestment. GI provides recipients with security, time, and support to enable their transition into adulthood and shows promise for improving mental and physical health outcomes. To date, few GI pilots have targeted emerging adults. The BEEM trial seeks to determine whether providing GI to BEA improves financial wellbeing, mental and physical health as a means to address …

The Impetus Of International Security In European Integration: The Nature Of Eu Common Security And Defense Policy, Osman Goktug Tanrikulu

Dissertations and Theses

This study explores the complicated relationship between security considerations and the European integration process. The research uncovers specific security factors that have shaped the EU integration process. Applying policy alignment and collective efforts for governance, this study offers a methodological improvement to the conventional status quo satisfaction concept within power transition theory.

Findings indicate that external militarized actions targeting European nations only occasionally disrupted integration in the short term. Instead, inner coordination among member states vis-à-vis external actors, promoted integration. During the early stages of integration, alignment with the EU collective was crucial, while aligning with regional leader Germany became …

Decriminalizing Drugs: A Comparative Study Of Oregon In An International Context, Fox Millsaps

University Honors Theses

Oregon made history in 2020 when voters joined together to approve ballot measure 110, the Drug Addiction Treatment and Recovery Act, which decriminalized personal amounts of all illicit substances. This was done in a bid to begin treating the ongoing drug crisis as a public health issue as opposed to a criminal justice issue. While Oregon may be the first in the nation to make such a move, they are not the first government to experiment with decriminalizing 'hard drugs.' Some argue that Oregon’s model was based on Portugal's decriminalization effort and point to Portugal's success as a potential outcome …

Understanding Connections Between Mobility, Transportation, And Quality Of Life In Refugee Communities In Tucson, Arizona, Orhon Myadar, Arlie Adkins, Maia Ingram, Nicole Iroz-Elardo

TREC Final Reports

In this multidisciplinary research project we aimed to study mobility challenges that refugees in Tucson, AZ, experience after their resettlement. Using qualitative and quantitative data collected from interviews and survey data, we argue that mobility shapes the ways refugees foster social connections, attain employment and access educational opportunities. Accordingly, barriers to mobility negatively impact refugees’ perception of well-being in post resettlement. However, these challenges are not experienced evenly. Nor are refugees passive subjects who lack agency in overcoming various barriers they experience. The study reveals the resilience of the refugee community in navigating the intersectional challenges they confront related to …

Marginalized Populations’ Access To Transit: Journeys From Home And Work To Transit, Miriam J. Abelson, Ivis Garcia, Sadika Khan, Amy Lubitow, Nicholas Puczkowskyj, Marisa A. Zapata

TREC Final Reports

Previous scholarship has shown that low-income individuals who also might identify as racial, ethnic, and gender minorities (such as transgender and gender nonconforming) are more likely to be dependent on public transportation. What remains understudied is how these marginalized groups, given their intersectional identities of oppression, might experience transit. The primary research question guiding this project is how do people with intersecting marginal identities experience social exclusion as they travel via mass transit? To answer the above research question, we employed a photovoice methodology and video-call interviewing, in Portland, OR, and Salt Lake City, UT. Across these two sites we …

Developing Public Service Leadership: Understanding The Field Immersion/Comparative Cases Model For Mid-Career Professional Education In Environment And Natural Resources Leadership, Erin M. Steinkruger

Dissertations and Theses

Public administrators in the United States face increasingly complex challenges and are called to leadership by position and in practice. In a hyper-pluralistic society, individuals must lead from where they sit, arbitrating value differences in day-to-day functions and taking on adversity and uncertainty in pursuit of the public good. These individuals are served by a variety of leadership training programs both internal and external to their organizations. This study characterizes the field immersion/comparative cases (FICC) model for public service leadership development and uses a grounded theory approach to build understanding about how individuals learn about leadership; what learning outcomes emerge …

Extreme Heat Vulnerability Among Older Adults: A Multi-Level Risk Index For Portland, Oregon, Jacklyn N. Kohon, Katsuya Tanaka, Dani Himes, Paula Carder, Eiji Toda, Bryant Carlson

Institute on Aging Publications

Background and Objectives

Extreme heat is an environmental health equity concern disproportionately impacting low-income older adults and people of color. Exposure factors, such as living in rental housing and lack of air conditioning, and sensitivity factors, such as chronic disease and social isolation, increase mortality risk among older adults. Older persons face multiple barriers to adaptive heat mitigation, particularly for those living in historically temperate climates. This study measures two heat vulnerability indices to identify areas and individuals most vulnerable to extreme heat and discusses opportunities to mitigate vulnerability among older adults.

Research Design and Methods

We constructed two heat …
