Evaluation Of Driver Comprehension And Compliance Of Red Colored Pavement Markings For Transit Lanes In Portland, Oregon, Nathan Mcneil, Christopher Monsere, Jennifer Dill

Urban Studies and Planning Faculty Publications and Presentations

Many U.S. agencies have experimented with red colored pavement markings in transit lanes to enhance the message that they are restricted to transit vehicles. This study evaluates non-transit drivers’ comprehension of and compliance with red colored lane markings in transit priority lanes intended to communicate lane restrictions and appropriate turning and merging locations. Two complementary research methods were used: 1) an online survey of drivers’ comprehension of red colored pavement markings; and, 2) evaluation of video collected at locations pre and post installation of red colored pavement markings. In the survey, most drivers recognize the red pavement color as a …

Centering Communities Of Color In The Modernization Of A Public Health Survey System: Lessons From Oregon, Daniel F. López-Cevallos, Kusuma Madamala, Mira Mohsini, Andres Lopez, Roberta Hunte, Ryan Petteway, Tim Holbert

School of Social Work Faculty Publications and Presentations

Context: Public health survey systems are tools for informing public health programming and policy at the national, state, and local levels. Among the challenges states face with these kinds of surveys include concerns about the representativeness of communities of color and lack of community engagement in survey design, analysis, and interpretation of results or dissemination, which raises questions about their integrity and relevance.

Approach: Using a data equity framework (rooted in antiracism and intersectionality), the purpose of this project was to describe a formative participatory assessment approach to address challenges in Oregon Behavioral Risk Factor Surveillance System (BRFSS) and Student …

The Affective Discourses Of Eviction: Right To Counsel In New York City, Hadley Savana Bates

Dissertations and Theses

This study explores the interrelationships of urban policy, affect, and power through a critical discourse analysis of New York City's "Universal Access to Legal Services" / "Right to Counsel" ordinance, a 2017 initiative that has persisted amidst the evolving landscape of eviction diversion following the outbreak of Covid-19. By examining archival documents regarding the groundbreaking policy, this research reveals how affective discourses regarding vulnerability, stress, and solidarity situate political actors in relation to urban policy, political movement, and the material conditions of survival. Drawing upon critical policy studies and affect theory, this study underscores the affective dimensions of policy mobility …

A Just Futures Framework: Insurgent Roller-Skating In Portland, Oregon, Célia Camile Beauchamp

Dissertations and Theses

Since the beginning of the COVID-19 pandemic in 2020, insurgent roller-skating has 're-emerged' as a popular use of urban space. Drawing on spatial justice theories, futures literature, and queer spatial theory, this study theorizes a four-part just futures framework to analyze the nuance and tension within the roller-skating scene in Portland, Oregon. The just futures framework: 1) creates a space for expanding planning practice to reflect overlooked and suppressed perspectives on urban space; 2) explores insurgent urbanism’s contradiction between the reification of hegemonic systems and its counter-hegemonic and subversive qualities; and 3) assesses the spatial and planning implications of insurgent …

Effects Of Language Status, Community Advice, And Parent Beliefs On Heritage Language Maintenance In The U.S.: A Scoping Review, Jasmine Loeung

University Honors Theses

This scoping review examines the effects of language status, community advice to parents, and parents' beliefs on heritage language maintenance within a U.S. context. A total of 34 articles met the inclusion criteria. Four key themes were identified as follows: (1) status of a language in society affects maintenance, (2) parents' beliefs about the impact of the heritage language affect family language practices, (3) community advice impacts parents' beliefs and practices, (4) other factors affecting maintenance of the heritage language across generations. Overall, HL maintenance was observed as a dynamic relationship between a variety of factors, with individuals as well …

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 …

A Call To Action For Disability And Rehabilitation Research Using A Discrit And Disability Justice Framework, Toni Saia, Rana Yaghmaian, Rachel Cuesta, Carlyn Mueller, Roxanna N. Pebdani

Counselor Education Faculty Publications and Presentations

Purpose: Disability and ableism exist within a societal context that does not ignore the many facets of a person’s identity, however often our disability research does not recognize how experiences vary based on the intersecting identities individuals hold. This article utilizes Intersectionality, Dis/ability Critical Race Studies (DisCrit), and Disability Justice to identify ways for rehabilitation researchers to adapt their research practices for maximum inclusivity and representation.

Materials and Methods: Using these three frameworks, we have developed a call to action including recommendations for rehabilitation researchers to consider as they design and implement research projects.

Results: Incorporating these frameworks provides an …

Water Quality Land Cover Change And Water Quality In Wetlands At The City Of Gresham, Or, Evelyn Barajas, Michael Gonzalez

altREU Projects

The City of Gresham, Oregon has implemented constructed wetlands around the area as an attempt to collect, filter, and purify water from different sources such as rain, agricultural waste, and domestic waste. We focused our research on three different facilities: Columbia Slough Water Quality Facility (CSWQF), Fairview Creek Water Quality Facility, and Brookside Water Quality Facility. For each of these, we conducted tests and looked at the concentration levels for nitrogen and phosphorus nutrients such as NH3-N (ammonium), NO3-N (nitrate), TKN (total Kjeldahl nitrogen), O-PO4 (phosphate), and Total P (total phosphorus), as well as heavy metals like Total Cu (total …

Heat Mapping Crime: A Data-Driven Approach To Policing In New York, Beruktawit Gebreamlak, Daniel Ochoa

altREU Projects

In the aftermath of the COVID-19 pandemic, New York City has seen a surge in criminal activities. In 2023, major crime continues to be higher compared to pre-pandemic levels. Although progress is being made to reduce the number of murders and robberies, law enforcement is continuing to struggle with increases in felony assaults and car thefts. Our project serves to benefit members of the community and law enforcement alike. We created a heat map, which is a visual representation of data that uses colors to represent different values. In the context of crime mapping, our heat map is used to …

Quantifying Damages To Soil Health And Emissions From Land Development In The State Of Illinois (Usa), Elena A. Mikhailova, Hamdi A. Zurqani, Zhenbang Hao, Mark A. Schlautman, Gregory C. Post, George B. Shepherd, Christopher C. Post, Renee M. Dixon

Geography Faculty Publications and Presentations

The concept of soil health is increasingly being used as an indicator for sustainable soil management and even includes legislative actions. Current applications of soil health often lack geospatial and monetary analyses of damages (e.g., land development), which can degrade soil health through loss of carbon (C) and productive soils. This study aims to evaluate the damages to soil health (e.g., soil C, the primary soil health indicator) attributed to land developments within the state of Illinois (IL) in the United States of America (USA). All land developments in IL can be associated with damages to soil health, with 13,361.0 …

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 …

Urban Sustainability Implementation And Indicators In The United States: A Systematic Review, Heejun Chang, Arun Pallathadka, Idowu Ajibade

Geography Faculty Publications and Presentations

Urban sustainability is the goal of many cities in the world, yet very few have achieved a level of sustainability that goes beyond the most basic environmental objectives. The practice and assessment of sustainability implementation are greatly compounded by lack of funding, technical know-how, political will, and the power disparity between dominant institutions and marginalized communities. This systematic analysis of urban sustainability literature involved the review of 241 studies published between 2010 and 2022. We critically examined current debates and challenges in urban sustainability, identifying gaps and opportunities and providing recommendations for creating equitable, just, and sustainable urban futures. We …

Spatial Analysis Of Streamflow Trends In Burned Watersheds Across The Western Contiguous United States, Heejun Chang, Will B. Long

Geography Faculty Publications and Presentations

Despite increasing magnitude and frequency of wildfire, understanding hydrological processes contributing to changes in streamflow is not well examined for the entire western contiguous United States (WCONUS). This study provides insight into whether considering spatially varying watershed characteristics, including burn severity patterns, can better explain streamflow trends at broad spatial and temporal scales. Standard geographically weighted regression (GWR) and multi-scalar (MS) GWR were benchmarked against ordinary least squares (OLS) regression to determine if spatially varying coefficients could better explain spatially varying patterns and processes of peak flow, low flow, center timing of flow, and flashiness trends in burned watersheds. In …

Wildfire Risk Governance From The Bottom Up: Linking Local Planning Processes In Fragmented Landscapes, Matthew Hamilton, Max Nielsen-Pincus, Cody Evers

Environmental Science and Management Faculty Publications and Presentations

The growing scale of natural hazards highlights the need for models of governance capable of addressing risk across administrative boundaries. However, risk governance systems are often fragmented, decentralized, and sustained by informal linkages among local-level risk mitigation planning processes. Improving resilience to the effects of environmental change requires a better understanding of factors that contribute to these linkages. Using data on the patterns of participation of 10,199 individual stakeholders in 837 community wildfire protection plans (CWPPs) within the western U.S., we document the emergence of a locally clustered but spatially extensive wildfire risk governance network. Our evaluation of factors that …

Rift-Induced Disruption Of Cratonic Keels Drives Kimberlite Volcanism, Thomas M. Gernon, Stephen M. Jones, Sascha Brune, Thea K. Hincks, Martin Palmer, John C. Schumacher, Rebecca M. Primiceri, Matthew Field, William L. Griffin, Suzanne Y. O'Reilly, Derek Keir, Christopher J. Spencer, Andrew S. Merdith, Anne Glerum

Geology Faculty Publications and Presentations

Kimberlites are volatile-rich, occasionally diamond-bearing magmas that have erupted explosively at Earth’s surface in the geologic past^1,2,3. These enigmatic magmas, originating from depths exceeding 150 km in Earth’s mantle¹, occur in stable cratons and in pulses broadly synchronous with supercontinent cyclicity⁴. Whether their mobilization is driven by mantle plumes⁵ or by mechanical weakening of cratonic lithosphere^4,6 remains unclear. Here we show that most kimberlites spanning the past billion years erupted about 30 million years (Myr) after continental breakup, suggesting an association with rifting processes. Our dynamical …

The Impact Of Climate Change On Selected Pnw Watersheds Through The Lens Of Western Red Cedar Habitat, Jordan T. Hamann

Dissertations and Theses

Climate change is a real phenomenon that is exacerbating existing natural processes and developing into a new normal for the planet. This change may be devastating for Pacific Northwest populations of Western Red Cedar (WRC) west of the Cascade Mountain range in the states of Oregon and Washington. WRC is a valuable tree species for reasons both economic and cultural. Dieback among WRC is following an accelerating trend. Since dieback is usually followed by tree mortality, understanding its causes and distribution is beneficial to the overall success of the species going into the future.

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 …

Disentangling Groundwater Dynamics At Oregon's Mckenzie River Headwaters, Taylor Nicole Salazar

Dissertations and Theses

Widespread mountain snowpack declines have been occurring across the western United States over the last century, and are increasing in duration and severity, with several record-breaking low-snowpack years in the last decade. In the Pacific Northwest, summer streamflow is largely a result of melting snow and groundwater discharge, as summers are typically dry and warm in this Mediterranean bioclimate, thus making spring-fed rivers critical for regional water resources. However, current trends and predictions in hydroclimate modeling indicate spring-fed rivers will experience reduced summer discharge driven by the increasingly larger impact of anthropogenic climate change (warming) on (decreased) mountain snowpack. A …

Radical Urban Natures: Mitigating Urban Heat With Nature-Based Techniques In Portland, Oregon, Heather Day-Melgar

Dissertations and Theses

Anthropogenic rising heat associated with climatic changes in the built environment has become a serious global issue. The built environment is often comprised of impermeable, paved surfaces, lack of vegetation to make way for development, tree removal, and loss or alteration of urban waterways, which leads to a degraded ecosystem for humans and non-human life, and less of an ability for carbon capture, all of which contribute to higher urban temperatures. This alteration of the existing natural environment leads to populations often unable to conceptualize that a built environment is still an ecosystem, and restoration is possible and necessary for …

Using Queer Of Color Theory To Analyze Latinidad, Maria I. Castro-Mendoza

Amplify: A Journal of Writing-as-Activism

Queer of Color Theory (QOCT) has emerged as a new field of study with the rise of LGBTQ+ visibility in the modern day political landscape. QOCT is an extended analysis of queer theory that explicitly and intentionally takes into account race, imperialism, and colonialism. Queer of color theory can be used to create or expand upon an already existing theory, and has roots in Black feminism. Using queer of color theory as a method of analysis, this essay discusses the black and indigenous erasure within the Latinidad movement and seeks to examine those who have been systemically left out of …

Participatory Mapping Of Tree Equity, Preferences, And Environmental Justice In Portland, Or, Katharine Vezin Gregory

Dissertations and Theses

Studies have shown that marginalized communities do not have the same access as more privileged groups to urban tree canopy cover due to historic and current processes of discrimination and disinvestment. This study explores the lived experiences, narratives, and values related to trees and greenspaces for residents of Portland, OR, through participatory mapping focus groups. It uses an environmental justice and urban political ecology framework to examine how values, lived experiences, and narratives compare for Portland residents across neighborhoods, socio-economic status, and racial or ethnic identity and how the changes that matter to residents can inform more just urban greening …

Who Puts The "Support" In Supportive Housing? The Impact Of Housing Staff On Resident's Well-Being, And The Potential Moderating Role Of Self-Determination, Kenna Estell Dickard

Dissertations and Theses

The provision of residential and community-based services for individuals with serious mental illness (SMI) has become increasingly important following the deinstitutionalization movement. Much of the existing research on supportive housing focuses on housing outcomes rather than exploring how the program helps its residents thrive in the broader community. This study draws upon data collected from 176 people with SMI residing in 16 supportive housing locations in Portland, Oregon. Analyses employed an ecological approach, exploring how housing staff support relates to residents' well-being at three levels of analysis: loneliness (interpersonal level), residential satisfaction (housing and neighborhood level), and sense of community …

What Explains Spatial Cariations Of Covid-19 Vaccine Hesitancy?: A Social-Ecological-Technological Systems Approach, Arun Pallathadka, Heejun Chang, Daikwon Han

Geography Faculty Publications and Presentations

While COVID-19 vaccines have been available since December 2020 and efforts have been made to vaccinate the maximum population, a large number of people are continuing to be hesitant, prolonging the pandemic in the US. While most previous studies investigated social, economic, and demographic variables that are associated with COVID-19 vaccine hesitancy, we added ecological and technological variables to better understand the spatial variations of vaccine rates in the contiguous United States using spatial regression and geographically weighted regression (GWR) models. We aim to identify spatially varying social, ecological, and technological factors that are associated with COVID-19 vaccination rates, which …

Embryonic Development Of Natural Annual Killifish Populations Of The Genus Austrolebias: Evolutionary Parallelism And The Role Of Environment, Hellen Schlueb, Daniel Blanco, Daniel García, Jason Podrabsky

Biology Faculty Publications and Presentations

1. Repeated, independent emergence of the same trait within different phylogenetic lineages is termed parallel evolution. It typically occurs as a result of similar selective pressures. Annual killifish have adapted to survive in the extreme habitat of temporary pools on three continents and present an especially amenable system for studying fundamental principles of evolutionary parallelism. When the pools dry, annual killifish embryos survive through the dry phase in the bottom substrate in a stage of dormancy—a diapause. The diapause is a complex set of three different developmental stages, none of which is obligate, thus leading to a multitude of potential developmental …

Enhancing The Definitions Of Climate-Change Loss And Damage Based On Land Conversion In Florida, U.S.A., Elena A. Mikhailova, Zhenbang Hao, Hamdi A. Zurqani, Mark A. Schlautman, Gregory C. Post, George B. Shepherd, Sarah J. Kolarik

Geography Faculty Publications and Presentations

Loss and damage (L&D) from climate change result from past and current greenhouse gas (GHG) emissions. Current definitions of L&D exclude GHG emissions even though they represent L&D to human beings and the environment. This study’s objective was to identify and quantify the L&D from GHG emissions associated with land developments using the state of Florida (FL) in the United States of America (USA) as a case study. All land developments in FL caused various L&D (20,249.6 km2, midpoint 3.0 1011 of total soil carbon (TSC) losses with midpoint $50.3B (where B = billion = 109, USD) in social costs …

The Impact Of Sars-Cov-2 On The Consolidated Meatpacking System In The United States, Judith R. Solomon

Anthós

The Sars-Cov-2 virus has had a particularly intense impact on the meatpacking industry in the United States. In this paper I provide a brief introduction to the social, economic, and political realities that lead to mass deaths of meatpacking workers from COVID, and the impact of a consolidated meatpacking system on disease mitigation. These workers are considered expendable due to a lack of power.

On Occupying: Women's Representation In The Israeli-Palestinian Conflict, Emma Hillstead

University Honors Theses

Scholars of peace and conflict studies have begun to investigate the impact the inclusion of women has on the success of peace talks that seek to resolve violent conflict. Many of these scholars have found that when women are included at the negotiating table, the likelihood for the conflict to come to a peaceful conclusion increases. With the historical, religious, and cultural nuances, this paper seeks to apply the existing research on this subject to that of the Israeli-Palestinian conflict. This paper first analyzes the positionality of women within the Israeli-Palestinian conflict, specifically looking at access to power, then applies …

Network Tango: Examining State Dispositions Toward Attribution In International Cyber Conflict, Robert Riley Turner

University Honors Theses

Cyberspace is an environment of international conflict often sought out due to its ability to create significant effects at little cost, and obfuscating the ready attribution of hostility. One avenue toward streamlining the attribution of hostile actions in cyberspace is the introduction of a due diligence of data transparency amongst states. This level of data transparency must somehow be incentivized. The following study surveys the geopolitical dispositions of three major powers that utilize cyberspace as a venue of conflict: The United States, China, and Russia; in order to determine how each nation might interact with an international due diligence of …
