Post-Fire Erosion And Debris Flows In The Western Pacific Northwest, United States: Recent Science And Opportunities, Sara A. Wall, Kevan Moffett, Annette Patton, Ben Leshchinsky, Andrew C. Wilcox, Maryn Sanders, Heejun Chang, Josh Roering

Geography Faculty Publications and Presentations

Most research into post-fire geomorphology has been conducted in regions with frequent fire, such as in dry Mediterranean and temperate climates and less has been conducted in wet forests where wildfire is now expanding with climate change. Because climate, soils, topography, vegetation, management legacies and fire history influence post-fire geomorphic processes, research into post-fire erosion and debris flow hazards across a broader set of climatologies is needed. The western Pacific Northwest (wPNW) of the United States is susceptible to multiple types of post-fire debris flows (i.e. shallow landslide-initiated and runoff-generated) that can be initiated by longer-duration lower-intensity rainfall compared to …

Unmanned Aerial Support Program In Portland Police Bureau: A Case Study, Eiryn Renouard

Dissertations and Theses

With the Portland Police Bureau (PPB) adopting drone technology in 2024 as a tactical tool, officers have begun to experience change in the way they approach their roles as they learn to work in conjunction with this new technology. Known as the Unmanned Aerial Support program (UAS), this drone program is embedded into PPB's patrol unit. The recency of the program offers an opportunity to examine how a new program using new technology builds its culture and impacts the perspectives and behaviors of its participating officers. By interviewing officers and conducting field observations of the officers and drones in action, …

Experiences Of Psychological Recovery From Work In Second-Generation Asian Americans, Laura Yang

Dissertations and Theses

Individuals of Asian descent make up approximately 7.4% of the U.S. population. As one of the fastest-growing minority groups, their population is projected to reach nearly 15% by 2065, with 38% being foreign-born – surpassing all other racial minority groups. Despite their increasing presence in the U.S. workforce, research on Asian workers' nonwork experiences remains limited. One key unexplored area is how Asian workers engage in recovery after work, considering their unique cultural and racialized experiences. Drawing on literature examining psychological recovery from work, this qualitative study employed multiple methods of analysis, both listening guide method and thematic analysis, to …

Fuel Tank Seismic Stability Program-Informed Displacement Maps Of Portland's Critical Energy Infrastructure Hub, Ana Tijerina Esquino

Dissertations and Theses

Oregon's Critical Energy Infrastructure (CEI) Hub in northwest Portland contains a large portion of the state's liquid fuel storage and distribution capacity and is located in an area susceptible to liquefaction and earthquake-induced permanent ground deformation during a Cascadia Subduction Zone earthquake. Initial Seismic Vulnerability Assessments submitted under Oregon's Fuel Tank Seismic Stability program provide valuable facility-specific information, but the assessments vary in subsurface characterization, treatment of fine-grained soils, ground motion selection, and deformation estimation methods. This variability complicates interpretation of regional seismic risk and motivates a consistent corridor-scale analysis.

This thesis develops CPT-informed displacement estimates for representative cross sections …

Intersectional Pathways To Prison And Sentence Disparities: Exploring The Role Of Race, Gender Identity, And Sexuality In Women’S Sentencing Outcomes, Jae Collett

Dissertations and Theses

This study explores the relationship between race, gender identity, sexuality, and prison sentence length using data from the Survey of Prison Inmates, 2016. While state and federal guidelines are ostensibly in place to prevent disparate sentencing outcomes, research still finds disparities in prison sentence lengths across identities of defendants. Women generally receive more lenient sentences than men, and may be shown chivalry when processed through the criminal legal system. However, qualifications for chivalrous treatment have historically only been accessible to certain women (i.e. cisgender, heterosexual, white women). The social and institutional exclusion queer women and/or women of color experience may …

Low Cost Lightning Localization At Microwave Frequencies, Bradley Glaubitz

Dissertations and Theses

High precision lightning localization is essential for atmospheric research and public safety, yet the high cost of traditional VLF/LF systems restricts high resolution detection primarily to well funded agencies. Furthermore, conventional low frequency receivers often overlook microwave frequency emissions associated with lightning leader development. This thesis proposes a compact, low cost microwave frequency localization system operating in the 1.42 GHz band to provide an accessible alternative for high resolution mapping. The methodology utilizes an ARM Cortex M0+ microcontroller and a triggered 64 MHz 32 bit counter synchronized to a GPS Pulse Per Second (PPS) signal, achieving a temporal resolution of …

The Kashmir Conflict After The Abrogation Of Articles 370 And 35a Of The Indian Constitution: Geopolitical Dynamics And Human Security Implications, Rizwan Ali

Dissertations and Theses

The abrogation of Article 370 of the Indian Constitution on August 5, 2019, revoked the special autonomous status of Jammu and Kashmir (J&K) under the Indian administration. It further bifurcated it into two Union Territories under central Indian control. The move came amid a severe security lockdown and communication blackout that lasted for months. It was followed by instrumental legal, social, and economic developments that directly affected the area’s disputed status and the human rights of its residents. This research examines the geopolitical and human security implications of the abrogation and subsequent developments through a qualitative, analytical design, integrating Edward …

"But Oh, What Harm Those Basics Would Cause": How Journalists Can Better Interview Vulnerable Sources Utilizing An Ethic Of Care, Noah Carandanis

University Honors Theses

Traditional journalistic ethics have emphasized detachment from sources and objectivity guiding journalists' practices. In this thesis, I explore the contribution of care ethics to the field of journalistic ethics, emphasizing care in relation to interviewing vulnerable sources. I claim that the traditional objective, detached ethical status quo in journalism is insufficient in the context of reporting on mass shootings. This thesis argues that caring journalistic practices should be utilized when interviewing traumatized, vulnerable sources. In the first part, I present the issue of traditional journalistic practices through my personal experiences. I also discuss the philosophical underpinnings to journalist's objectivity criterion. …

Aid And Assist Cases In Multnomah County: An Exploration Of Ors 161.370, Savannah Jurasek

Dissertations and Theses

Individuals with severe mental illness (SMI) are highly overrepresented in jails. In Oregon, these individuals can be eligible for what is referred to as the aid and assist process (ORS 161.370) which is designed to facilitate restorative care in efforts to ensure that vulnerable individuals can rationally participate in their criminal proceedings. However, continuous escalation in aid and assist orders (109.3% between 2011-2025) has led to strain on the Oregon State Hospital, the primary care facility for this population. As a consequence, defendants with SMI are spending unnecessary time in custody, despite hospitalization admission guidelines governed by previously decided case …

Homelessness And Business: Perception, Affect And Opportunity, Asatur Nor-Ashkarian

University Honors Theses

This thesis examines the relationship between business owners and individuals experiencing homelessness within urban commercial districts in the United States, arguing that the dynamic is shaped primarily by spatial concentration, uneven power structures, economic pressure, and public framing rather than simple conflict between competing interests. Drawing on stakeholder analysis, business perception surveys, a mixed-methods study, and an original content analysis of 50 news articles spanning 23 states, this thesis identifies a consistent pattern: business owners broadly perceive homeless presence as negatively impacting safety, cleanliness, and consumer behavior. Local news media reinforces those perceptions through predominantly negative framing of homeless individuals. …

Historic Parkrose: Planning For Vacant Properties, Rowan Anderson, Julia Cruz Jones, Akasha Lawrence Spence, Clara Lietz, Cal Storrs

Master of Urban and Regional Planning Workshop Projects

Crescent Consulting was engaged by Historic Parkrose, a Portland-based non-profit, to analyze vacant and under-utilized properties along Northeast Sandy Boulevard within the Historic Parkrose Business District. The area has been the focus of many planning efforts at the neighborhood, city, and state level that have identified community needs and priorities, yet implementation has been limited. Forthcoming Tax Increment Financing (TIF) funding may create opportunities to implement these plans and encourage reinvestment that will contribute to the corridor’s vitality and economic capacity. This report is a resource for evaluating and prioritizing vacant lot redevelopment opportunities in Parkrose, helping align future investment …

Who Keeps Us Safe? Youth Resistance And Security Regimes At The Neoliberal University, Arwen Hansell

University Honors Theses

In a political climate shaped by surveillance, labor precarity, policing, and immigration enforcement, questions of (in)security increasingly organize everyday life. Governments justify security measures through the language of public safety, even as many people experience insecurity surrounding housing, healthcare, employment, and the future itself. Although critical security studies have examined policing, militarism, and surveillance extensively, youth are often overlooked as political actors despite their central role in social movements. This study addresses that gap by focusing on student labor organizers and activists navigating (in)security. Using collaborative ethnography, I conducted fieldwork at protests, labor organizing meetings, workshops, and demonstrations connected to …

The Power Of Perception: Latine Threat Narratives And Immigration Control In The United States, Nina Gallo

University Honors Theses

Despite America's rich history as a self-proclaimed "nation of immigrants," immigration policy in the United States has functioned as a tool of social control designed to systematically exclude and restrict groups of people that pose a perceived threat to national identity and safety. This perceived threat has effectively been communicated through harmful narratives that stratify immigrant communities from the rest of society. Through this framing, support for punitive immigration policies thrives. Currently, Latine immigrants and their families have been the target of discriminatory immigration policies and enforcement tactics. No work to date has synthesized the current state of the immigration …

Justice By Geography: District-Level Variation In Pretrial Release Outcomes Across Oregon, Ethan Loomis

Dissertations and Theses

AbstractOregon’s pretrial system operates under a common statewide legal framework, yet detention and release outcomes do not appear fully consistent across jurisdictions. Earlier research on pretrial decision-making has largely focused on judicial discretion, individual-level legal factors, and the use of risk assessment tools, while giving less attention to the district-level environments in which those decisions are made. This study examines whether variation in institutional capacity, political context, demographic composition, and socioeconomic conditions corresponds with differences in pretrial outcomes across Oregon’s circuit court districts.

The study draws from focal concerns theory, racial threat perspectives, and organizational approaches to court decision-making. Rather …

The Great Plague Of Marseille, Lucy Herzig

Young Historians Conference

This paper examines the causes and consequences of the Great Plague of Marseille (1720-1722), which was one of Western Europe's last major outbreaks of the bubonic plague. Although European port cities had developed quarantine systems to prevent epidemics, Marseille’s outbreak revealed how these protections failed in practice. This paper argues that the plague became so devastating not because of a lack of institutional systems, but due to fragmented local authority, delayed government intervention, and the prioritization of economic interests over public health. Focusing on the arrival of the merchant ship Grand-Saint-Antoine, this paper analyzes how merchant elites influenced quarantine decisions, …

Key Issues For Speed Safety Cameras: Results From A Semi-Structured Interview Of Agencies In The United States, Sophia Semensky, Miguel Figliozzi

Civil and Environmental Engineering Faculty Publications and Presentations

Speed safety cameras (SSCs) are a recognized countermeasure for targeting speeding-related crashes, injuries, and fatalities. SSCs have been introduced in various cities and are steadily expanding in use both in the U.S. and internationally. The extensive literature review of domestic and international documents and research papers reveals that the U.S. has been comparatively slow to adopt SSCs, with some other countries implementing these systems more extensively and earlier. Many local agencies are eager to learn SSC best practices and implementation lessons within the U.S. context. In this research, key issues related to SSC implementation are explored through semi-structured interviews with …

Modeling The Combined Effects Of Forest Fire And Climate Change On Snow-Water Storage In The Oregon Cascades, Joseph D. Vigil

Dissertations and Theses

Forest fire and climate change are reshaping the snow hydrology of the Pacific Northwest of the United States, yet the combined effects of these disturbances on snow accumulation, storage, and melt timing remain poorly quantified in these Mediterranean mountain watersheds. This study integrates field-based snow and radiation observations with physically based modelling to evaluate how postfire forest structure, postfire snow albedo decay, and future climate change influence snow-water storage in the Breitenbush watershed of the western Oregon Cascades. This work was conducted as part of a broader U.S. Army Corps of Engineers effort to improve postfire hydrologic prediction and flood …

Goals And Budgets: An Exploratory Study Of Sequencing In Budget Simulation Engagement, Frankline Muthomi

Public Administration Faculty Publications and Presentations

Purpose:

The purpose of this study is to examine how the sequencing of budget simulations influences the alignment between priority goals and budgetary decisions. Drawing on behavioral perspectives, the study posits that two simulation sequences—goal setting to budgeting (default) and budgeting to goal setting (alternative)—shape individuals' budgetary responses, particularly the proximity between a program's total cost and the corresponding budgetary allocations. Design/methodology/approach This study employs a quasi-experimental research design using Balancing Act modules that enable participants to articulate their priority goals and corresponding resource allocations. Adult Americans (aged 18 and above) were recruited through an online crowdsourcing platform and randomly …

Post-Wildfire Water Quality And Aquatic Ecosystem Response In The U.S. Pacific Northwest: Science And Monitoring Gaps, Sara Wall, Jana E Compton, Ashley A. Coble, Beth M. Haley, Jiajia Lin, Allison Myers-Pigg, Justin Reale, Katie Wampler, Kevin D. Bladon, Kurt Carpenter, Heejun Chang, Multiple Additional Authors

Geography Faculty Publications and Presentations

An increase in the occurrence of large, high severity wildfires in the western Pacific Northwest (PNW), USA, has created an urgent need for science to better inform forest management and policy decisions to maintain source water quality in the region. The western PNW faces similar challenges to other regions with shifting wildfire regimes and large population centers reliant on surface water from forested catchments. However, the uniquely wet and highly seasonal climate of the western PNW suggests that findings from other, more frequently burned regions may not be directly applicable. To identify science, monitoring, and management gaps and opportunities in …

Citizen Engagement In Budget Simulation: Examining The Effectiveness Of Balancing Act Modules In Aligning Public Priorities And Allocation Choices, Frankline Muthomi

Public Administration Faculty Publications and Presentations

This study investigates the extent to which individuals exhibit consistency in their preferences during sequential budget simulation exercises, as well as the factors that shape these preferences. Grounded in behavioral and citizen participation frameworks, the analysis demonstrates that the simultaneous use of priority-setting and budget-balancing modules encourages participants to allocate resources in ways that reflect their previously articulated priorities. While instances of inconsistency remain common, preference consistency is associated with participants’ sustained support for their favored programs, their commitment to ensuring adequate resource allocation, and, to some extent, their willingness to finance these programs. The findings suggest that the integrated …

Erasing The Artist, Policing The City: Michael Stewart And New York’S War On Graffiti, Vladislav Kirilov

Anthós

The 1983 death of Michael Stewart, a young Black graffiti artist, exposes the violent logic at the center of New York City’s War on Graffiti. Under Mayor Ed Koch and the rise of broken windows policing, graffiti was framed as a racialized symbol of disorder used to justify intensified control of public space. Rather than becoming political in this moment, graffiti is understood here as an already politicized form of expression shaped by racial and spatial inequality. The article examines how Stewart’s killing made police violence visible, provoking responses from artists, activists, and graffiti writers while revealing the human costs …

Home Rule, Dillon’S Rule, And The Legal Shape Of Local Governance, Bradon J. Rothschild

National Policy Consensus Center Publications

Public policy in common law democracies such as the United States is dictated by many factors, which you might call streams or strands. While on the one hand the vox populi may insist on a certain action, governing coalitions of political leaders may deign another direction, or policy researchers may conclude a third option is better yet. All such options, however, are constrained by the legal parameters of governance as defined by constitutional, statutory, and case (jurisprudence, or stare decisis) law. Where these streams meet, public policy actions which are popularly supported, politically advantageous, technically effective, and (importantly) legal may …

Urban Wildlife In Your Backyard: Community Experiences With Coyotes And Outdoor Cats, Clarissa Emma Cressotti

Dissertations and Theses

Urbanization reshapes ecological processes by fragmenting habitat and altering patterns of human-wildlife interaction, often reducing biodiversity. However, at the household scale, residential yards can either enhance or inhibit ecological connectivity - functioning as informal habitat stepping stones or barriers to wildlife. This thesis examines how residents' environmental attitudes, wildlife experiences, and socio-demographic characteristics influence yard-level behaviors and shape the presence of urban-adapted wildlife species, particularly coyotes and domestic cats, across the Portland, Oregon metropolitan region. A mixed-methods, social-ecological framework guided the analysis, integrating survey data from 244 households with wildlife detections from motion-triggered cameras (Urban Wildlife Information Network, UWIN), citizen …

Plan Mano Dura: A Punctuated Political Act? Addressing Gang Violence In El Salvador, Carlos A. Arias

Hatfield Graduate Journal of Public Affairs

On July 23, 2003, Salvadoran President Francisco Flores introduced a punitive and militaristic gang-prevention measure, Plan Mano Dura (Plan Iron Fist), in an attempt to solve the gang phenomenon plaguing El Salvador. Although it turned out to be an abject policy failure, its future effects and significance would far outweigh its intended impact, essentially dictating how El Salvador would combat gang violence for the next 20 years and beyond. As such, it is essential to better understand how such an ineffective policy could arise as a policy approach. This paper examines whether Punctuated Equilibrium Theory (PET) can account for the …

#Clandestini: How Italy's Center-Right Parliamentary Coalition Frames The Migrant Crisis On Social Media, Jenna Lynn Depasquale

Dissertations and Theses

This dissertation examines the intersection of Italian neo-fascism, the Mediterranean migrant crisis, and digital media. Through a qualitative content analysis of the Twitter and Instagram posts made by Italy's center-right parliamentary coalition from 2014-2018, this research outlines frameworks that facilitate both the physical and social deaths of migrants. Twitter is a platform on which bite-sized xenophobic messages characterize migrants as criminals, spoiled youth, spreaders of infectious disease, and future terrorists--sometimes in a contradictory fashion. Instagram is a medium for conveying Italian identity and history, which disregards the longstanding contributions of people of color, including Muslims, in Southern Italy. Comment sections …

Dissertations and Theses

In an attempt to answer the question of what role the judiciary played in affecting access to public spaces from the 1960's to 2024, this thesis identifies an accumulation of patterns relating to the courts' role in accessibility of public parks and their amenities over this time period. The data supplied for this question is drawn from scholars focusing on judicial decisions and political theory relating to public spaces, including those mentioned above. The result of this study will include a close examination of the role the judiciary holds as a cornerstone institution in not only our democracy, but in …

Latino Threat Perceptions And Immigration Attitudes: An Examination Across Generations Of Latinos, Michelle Angel

Dissertations and Theses

Recently, immigration has been a major focus in U.S. politics, more importantly with the current administration pushing for the implementation of punitive immigration policies. Research shows that perceived Latino threat is associated with support of Trump and harsh border controls. While existing research has expanded the perceived Latino threat and punitive border control attitudes among non-Latinos, less is known about how perceived Latino threat and punitive border control attitudes function within their own group and how they might vary across different generations of Latinos. Accordingly, there has been a shift in Latino voting preferences, specifically across different generations of Latinos. …

Structure Vs Agency: The Intersectionality Of Race, Mental Health, And Homelessness, Jayley Martin

University Honors Theses

This project investigates the intersectionality between race, mental health, and homelessness, emphasizing the dynamic interplay between structural factors and individual characteristics. Through an integrative literature review, the research addresses the question of how race, mental health, and homelessness are interconnected. The findings suggest a distinct relationship between untreated mental illness and an increased risk of homelessness, particularly among marginalized racial groups. In addition, some mental illnesses, such as anxiety and depression, have a higher incidence among those who face conflict due to racial discrimination. Structural components such as systemic racism in social services and healthcare practices significantly impact access to …
