Should Dams Respond To Power Prices? Environmental Economics And Emissions Effects Of Hydropower Peaking, Levi Stephen Konrad-Shankland

Environmental Studies Senior Theses

Hydroelectricity stands to be particularly important to a decarbonizing power grid because unlike many renewables it is dispatchable. However, ramping up and down hydropower production at short notice to respond to power demand—hydropeaking—worsens many of the environmental harms of hydroelectricity (Bipa et al., 2024). In Chapter 1, I create a microeconomic framework to explain how and why revenue-motivated dams hydropeak.

In Chapter 2, I assess the extents to which six different case study dams around the US hydropeak, first by decomposing actual flow regime into combinations of counterfactual management objectives, and second with an index of flow variation alignment with …

International Students As Vectors Of Informal Diplomacy : Does Soft Power Matter More Than Dollars?, Alexis Carriere

Journal of Comparative & International Higher Education

This article examines the evolving rationales underlying government strategies to attract international students, with a particular focus on their role as vectors of informal diplomacy. While existing scholarship has largely analyzed international student mobility through individual motivations or institutional strategies, this study highlights the state-level logics that frame student mobility as a tool of soft power. Drawing on policy documents, political speeches, and scholarly literature, the article analyzes the approaches of the five permanent members of the United Nations Security Council—countries that remain among the world’s top destinations for international students—across three historical periods: 1945–1990s, 1990s–2010s, and 2010s–2025. Findings reveal …

The Degradation Of Prices: Platform Power, The Erosion Of Price Comparison, And Rebuilding Comparison Shopping In The Digital Economy, Stephanie T. Nguyen, Shaoul Sussman

Center for Law and the Economy

The ability to know the price of a product or service and then compare prices of similar products or services is a foundational cornerstone of consumer choice and competitive markets. Once, buyers could more easily compare identical products across multiple sellers. However, this process has systematically degraded over time and has become increasingly difficult to do in practice. When prices are a reliable signal of product and market value, consumers can make informed purchasing decisions and sellers can compete for business by offering more attractive prices to consumers. This is a core market force that keeps price levels in check …

Socioeconomic Inequalities In Health-Related Quality Of Life During The Covid-19 Pandemic: A Six-Country Comparison Using The Eq-5d-5 L, Joëlle Eijkens, Joshua M. Bonsel, You-Shan Feng, M. F. Bas Janssen, Erica I. Lubetkin, Juanita A. Haagsma

Publications and Research

Purpose

Despite the growing attention to health inequalities, there is no global consensus on how to measure socio-economic status. This study examined inequalities in health-related quality of life (HRQoL) during the early phase of the COVID-19 pandemic across six countries—China, Italy, the Netherlands, Sweden, the United Kingdom (UK), and the United States (US)—using three SES indicators: education level, income, and work status.

Methods

Between April and June 2020, individuals aged 18–75 years old completed a web-based survey. HRQoL was measured using the EQ-5D-5L Level Sum Score (LSS), where higher scores indicate poorer health. Country-specific differences in LSS across SES groups …

The Impact Of Religious Behaviors, Islamophobia, Gender Roles, Language Proficiency, And Education Levels On Mental Illness Stigma And Help-Seeking Behaviors Among Arab Women In The U.S., Rima Muhsen

Dissertations

The official U.S. census does not provide data on the number of Arab Americans in the United States, which hinders studies that focus on this population group to explore their needs and improve access to mental health services. Arab women in America represent a subgroup that has received insufficient attention from researchers, particularly regarding culturally sensitive topics such as mental health problems and their associated stigma. The influence of cultural, social, and religious factors on self-stigma associated with mental illness has not been adequately studied among this marginalized group. While previous research has suggested a relationship between self-stigma, social stigma …

Cathedral Park Strategic Action Plan: Guiding Community Development With Actionable Advocacy Strategies, Travis Mauzy, Dagny Daniel, Samuel Goldberg, Samantha Ishihara, Jacob Hagen

Master of Urban and Regional Planning Workshop Projects

The Cathedral Park Neighborhood Association (CPNA) is interested in adopting a Community Plan. Area-specific plans are addendums to the City of Portland Comprehensive Plan which give a neighborhood the opportunity to identify issues and priorities for long-range planning in their community.

Cathedral Park is currently a part of the St. John's/Lombard Plan (2004), but the neighborhood has experienced many changes since then, including new housing development, shifting demographics, and awareness of environmental threats such as the Critical Energy Infrastructure hub.

Gateway: Heat Resilience Focus Area Final Report, Jill Coleman, Sletsy Dlamini, Luke Gordon, Danny Harden-Ramella, Joe Kortenhof, Devery Sheridan

Master of Urban and Regional Planning Workshop Projects

In the Summer of 2021, Multnomah County experienced a heat dome that resulted in the tragic deaths of 75 people and caused 258 individuals to seek medical care in emergency rooms and urgent care facilities. While heat related treatment had been experienced in previous heat waves, no heat related deaths had been recorded by the county prior to the Heat Dome. Since 2021, heat-related fatalities have remained elevated above the pre-2021 baseline. Medical visits for illness and injury also remain elevated from 2021 onwards. Many of the more easily implementable short-term solutions have already been implemented in Portland, and the …

Investigating Potential Bias In Public Acceptance Of Restorative Justice: The Influence Of Situational And Offender Characteristics, Kiara Haynes

Student Theses

Restorative Justice has been an emerging justice mechanism in the U.S. since the 1970s that advocates are working to expand more widely throughout the justice system. Due to victims and the broader community of the offender being an integral part of the Restorative Justice process, it is critical to consider the general public's support of this novel justice mechanism, as well as the influence that social biases among the public may have on the experience of defendants going through the system. The study conducted examined the effect that social biases toward an offender's personal characteristics have on attitudes and opinions …

The Security Of Llm-Generated Code, Christopher Brian Gonzalez Ayala

Student Theses

The rapid adoption of Large Language Models (LLMs) in software development has transformed coding practices by enabling automated code generation, completion, and optimization. Despite these advantages, concerns persist regarding the security and reliability of LLM-generated code. This study presents a comprehensive evaluation of both the functional correctness and security of code produced by three prominent LLMs as of early 2026. A total of 4,800 code snippets were generated using 100 security-focused programming prompts derived from the OWASP Top 10:2025, translated across eight natural languages and two phrasing styles (literal and natural developer-oriented prompts). To assess performance, a multi-stage experimental framework …

Adversarial Robustness Of Perceptual Hashing Systems: A Unified Security Evaluation Framework, Avijit Roy

Student Theses

Social network platforms, child safety organizations, and image provenance systems use perceptual hashing to identify known child sexual abuse material (CSAM), support content moderation and reverse image search, and verify image integrity. Perceptual hashing works by producing similar fingerprints for visually similar images, even after common transformations such as compression, resizing, or minor brightness changes. This useful similarity-preserving property also creates an adversarial attack surface, as attackers can use AI-assisted or conventional image manipulation techniques to move a hash across a matching threshold while maintaining visual similarity, often without access to specialized hardware.

The security failures produced by adversarial attacks …

A Qualitative And Quantitative Comparative Analysis Of Ballistic Bone Trauma From Frangible And Full Metal Jacket Projectiles, Hajar S. Hassan

Student Theses

Ballistic bone research is essential as 90% of homicides with the use of a firearm include injuries to bone. Forensic anthropologists use ballistic bone trauma to gather details and reconstruct an event, but ballistic bone trauma depends on many intrinsic and extrinsic factors. These factors include the type of bone, the type of firearm, and the type of ammunition. As new ammunition and firearms emerge, the literature on ballistic bone trauma remains limited. This novel study compares the bone trauma from the most common projectile, the full metal jacket, to a frangible projectile which is made to break upon impact. …

Walking The Path Of Conocimiento: Understanding And Navigating Workplace Conflict Through A Chicana Feminist Lens, Elisa A. Ortega-Schultz

Dissertations

The growing presence of Latinas in the U.S. workforce underscores the need for deeper understanding of their workplace experiences. Latinas represent one of the fastest growing segments of the labor force; however, research consistently shows that this growth is not matched by equitable access to leadership, compensation, or culturally responsive workplace environments. Latinas continue to experience persistent barriers related to pay inequity, career advancement, cultural belonging, and overall well-being.

Conflict frameworks that account for the unique experiences of Latinas are needed, as dominant approaches rooted in neutrality, procedural efficiency, and Western individualism often fail to account for the embodied, relational, …

Less Prep, More Presence: Implementing Pattern Teaching In Library Instruction Lesson Planning To Reduce Stress, Liana Bayne-Lin

Faculty Scholarship

As a liaison librarian at an R2 university, I support three STEM departments in their teaching and learning needs. Like many liaison librarians, one of the main activities I do to provide that support is guest lecturing in classes on information literacy topics like finding, using, evaluating, and citing scientific information sources. Like many  liaison librarians, I didn't get a lot of pedagogy instruction in library school, and had to learn by doing during my first year. And, like many teaching librarians, my desire to connect with my students in a genuine, authentic way is deep.

Understanding Formal Financial Access In Indonesia: Evidence From Micro Data, M. Aulia Rachman, Yozi Aulia Rahman, Maulida Dewi Pangestika, Risanda Alirastra Budiantoro

Economics and Finance in Indonesia

This study examines the determinants of access to formal financial institutions using secondary household survey data from Indonesian Family Life Survey, Wave 5 (IFLS-5). Logistic regression analysis reveals that loan amount, savings, education level, age, housing status, and internet usage are positively and significantly associated with greater access. Individuals with higher savings, higher education, and homeownership exhibit a higher probability of utilizing formal financial services. Although the significance of internet usage varies across models, it remains a strong predictor when properly controlled, particularly due to its role in enhancing digital literacy. In contrast, income and health insurance ownership do not …

Trace: Temporal Rhetorical Analysis And Consistency Evaluation For Legislative Speech, David Hernandez

Master's Theses

Legislators frequently discuss the same policy issues across multiple hearings and legislative sessions, sometimes maintaining consistent positions and other times modifying or reframing their stance over time. Understanding how these positions evolve is important for analyzing political discourse and democratic accountability, yet identifying such shifts at scale remains difficult.

We introduce TRACE (Temporal Rhetorical Analysis and Consistency Evaluation), a system built on the Digital Democracy Database (DDDB) for detecting rhetorical inconsistency in California legislative hearing testimony. TRACE organizes utterances into speaker-anchored timelines indexed by bill and session, then applies hybrid semantic retrieval — combining dense BGE embeddings with BM25 lexical …

Temporal Integration In Music And Aesthetic Judgments: Assessing Musical Taste Through A Transformer-Based Approach, Sophia M. Senderak

Dissertations, Theses, and Capstone Projects

Music unfolds over time, requiring listeners to integrate information moment by moment to make aesthetic judgments. Although we know that music is likely processed on multiple timescales, it is not known which musical features contribute to short versus long timeframes. This study examined whether a computational measure of temporal integration could help explain aesthetic responses to music. Participants (N = 28) listened to 32 sixty-second clips of classical and electronic music, and continuously rated their enjoyment with a dial. After listening, they then gave an overall liking judgment for each clip. To quantify temporal integration, we derived an integration measure …

Neural Correlates Of Recognition Memory And Metamemory In Breast Cancer Survivors: An Event-Related Potential Study, Dishari Zaman Azad

Dissertations, Theses, and Capstone Projects

Breast cancer survivors (BCS) often report noticeable cognitive difficulties despite showing limited impairment on standardized neuropsychological tests. Some have theorized that this is simply an insensitivity of standardized testing to subtle cognitive changes (test-insensitivity hypothesis), whereas others have suggested there are early neural changes that are detected by patients but precede detection by these tests (early signal hypothesis) or that when they achieve normal performance, it is through saliently effortful compensatory processes (compensation hypothesis). The present study tested these theories by assessing metamemory and recognition memory retrieval in BCS and non-cancer controls (NCC) using both behavioral and event-related potential (ERP) …

Urban Sacred Grove: A Visioning For Collective Care, Preservation, Environmental Justice, And Resilience, Oluwadara A. Ojugbele

Dissertations, Theses, and Capstone Projects

My capstone explores how the concept of sacred groves—a community-based practice of conserving forest areas for cultural, spiritual, or religious purposes—can be reimagined as a framework for urban environmental stewardship and community care. Sacred groves have historically varied across time and place but consistently serve as protected spaces that honor divine forces, ancestors, and community values. In the Yoruba context, groves demarcate lush forests as abodes for oriṣas (divine forces) and spiritual beings, often containing shrines and artifacts that embody cultural beliefs. My capstone draws on the sacred grove concept and aims to illustrate how urban communities might adopt sacred …

Turning Boycott Into A Sustainable Opportunity: Leveraging Boycott To Boost Local Production And Enhance Local Market Competitiveness In Egypt, Alaa Maher

Theses and Dissertations

While existing literature largely concentrates on the consumer behavior dimensions of boycotts, limited attention has been paid to their structural economic implications for FDI and local production. This paper frames the 2023 boycott campaign as a demand shock in Egypt’s food and beverages sector. Dependency theory is applied to assess the pre-boycott stage, where MNCs’ market power created structural dependencies within the sector. Dynamic capabilities theory is employed to explain the heterogeneity in firm responses during the boycott and their attempts to acquire sustainable market share. Using a multi-case study design, qualitative in-depth interviews were conducted across 16 firms in …

How Much And How Fast Do Investors Respond To Equity Premium Changes? Evidence From Wealth Taxation, Andreas Fagereng, Luigi Guiso, Marius Ring

Cowles Foundation Discussion Papers

Using administrative panel data on Norwegian investors’ portfolios, we document strong but slow portfolio allocation responses to a persistent wealth-tax-induced shock to the equity premium. Short-run responses resemble the modest sensitivity documented using surveys. The longer-run responses are much larger and can be rationalized by moderate risk aversion. We document that equity premium shocks affect stock market entry but not exits, suggesting that entry costs dominate participation costs. Our finding of slow responses supports the asset-pricing literature that uses adjustment frictions to explain important asset-pricing puzzles, and has implications for optimal capital taxation when tax rates differ across assets.

Can Generative Ai Make Farming Decisions? Current Status And Future Pathways: A Case Study In Row Crop Production With Chatgpt, Nipuna Chamara, Yufeng Ge, Joe Luck, Yu Pan, Saleh Taghvaeian, Cory Walters, Christopher Proctor, Daran Rudnick, Daren Redfearn

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The agricultural decision-making process is experience-based, knowledge-dependent, time-sensitive, complex, and driven by historical data. Planting, fertilization, irrigation, and chemigation are key categories in farm decision-making, and currently there is no one-shot decision-support tool that covers all these activities. Generative Artificial Intelligence (AI) models are more advanced than traditional machine learning and deep learning models. These models have been trained on vast amounts of data from the internet, allowing them to accept unstructured data in various forms and generate human-like text, solutions to problems, and scenario predictions. Given this capability, we became interested in exploring the potential of generative AI in …
