Numerical Modeling Of Climate Change Impacts On Transportation Embankments, Amr Morsy, Mamata Sapkota, Emma Varela, Odalys Portillo

Mineta Transportation Institute

Embankments are essential components of transportation infrastructure, providing crucial support for long stretches of highways, railways, and other routes in California and around the world. Clay embankments are susceptible to weather-related deterioration processes that can gradually compromise their stability and, in some cases, lead to unexpected failures. Climate change, along with the associated shifts in weather patterns, is projected to adversely impact the weather-related deterioration processes, leading to exacerbated failures and/or shorter service life. Additionally, climate change is projected to increase the frequency of extreme precipitation events, leading to an increase in embankment failure potential. This study evaluated (1) the …

When Words Flow Like Water: How The Enbridge Line 3 Pipeline Environmental Impact Statement Failed To Prevent Hydrogeologic Harm In Minnesota, Carly Gutzmann

Journal of Earth and Life Science

For the aquifers of Minnesota, the environmental impact statement (EIS) was a promise of protection that never left the page. An environmental impact statement is meant to be an aid in the decision making process in order to ensure that projects consider potential environmental harms that may occur. However, they are often used instead as another regulatory box to check, rather than as active considerations when planning. As such, a project plan can be flawed from the start—if project developers only consider environmental impacts after they have already put considerable time, effort, and funding into their project as-is, they may …

The article explores the evolution of Advanced Practice Nurse (APN) roles in Switzerland and Kenya, highlighting their development, challenges, and influence on healthcare delivery. Despite notable differences in income levels and healthcare infrastructure, both countries are committed to strengthening primary care through the deployment of APNs. Switzerland uses APNs to address provider shortages and improve chronic disease management, whereas Kenya uses them to increase access in underserved areas. A comparative analysis explores how regulatory frameworks, educational models, scope of practice, and health system priorities influence the adoption of advanced practice nursing (APN). Switzerland’s established healthcare system supports the integration of …

Digital Redlining In The Smart City: Artificial Intelligence, Housing Law, And Structural Urban Inequality, Spurthi Nrusimhadevara

Undergraduate Scholarship and Creative Works

Artificial intelligence is increasingly used in urban housing systems, where it shapes decisions about tenant screening, rent pricing, lending, zoning, and neighborhood investment. Although these tools are often promoted as efficient and impartial, they frequently rely on historical data that reflect racial, economic, and spatial inequality. As a result, AI systems can reproduce discriminatory outcomes even when protected characteristics are not directly used. This paper examines digital redlining in the smart city and argues that algorithmic housing tools mirror long standing structural inequities that raise significant concerns under fair housing and civil rights law. It evaluates how automated screening, predictive …

Deterrence Without Peace: Nuclear Weapons And The Rising Threshold Of Warfare, Catie Clarke

CISLA Senior Integrative Projects

Nuclear weapons fundamentally changed the international political landscape, leading to the emergence of deterrence theory and the notion of the Long Peace. This paper challenges these claims, arguing that nuclear weapons facilitated a more violent and volatile international system rather than stability. Drawing on constructivist theory, this paper develops the Threshold of Violence framework – a normative model which asserts that nuclear weapons elevated the perceived upper limit of tolerable violence in international politics. This raised threshold generated three trends in the nuclear era: increased frequency of proxy wars, escalating levels of benefactor involvement, and greater severity of conflicts fought …

Organ Chips And Translational Research: Identifying And Examining New Ethical Issues, Melanie Jeske

Center for Medical Ethics and Health Policy Staff Publications

Organ chips, also known as organ-on-a-chip devices, tissue chips, or microphysiological systems, have emerged over the last decade as a promising translational technology amidst growing concern about the translational crisis between laboratory research and patient bedside. Pointing to high rates of failure between nonhuman animal models and safety and efficacy in humans, organ chips and similar new approach methods have attracted substantial public and private investment. As human-cell-based alternatives to animal models, organ chips promise more predictive, efficient, and ethical platforms for pharmaceutical and toxicity testing. Engineered cultivation systems that enable cells to assemble into tissue-like structures (e.g. kidney, brain, …

Center for Medical Ethics and Health Policy Staff Publications

The emergence and rapid adoption of digital health technologies (DHT) present unprecedented opportunities to democratize and reduce disparities in health care by monitoring health and disease at the point of care in all patients. However, limited access to DHT is becoming a major obstacle to realizing these goals. Access to DHT is influenced not only by well-recognized social determinants of health, but also by digital determinants of health, such as digital literacy and the need for broad access to digital infrastructure, as well as commercial and economic factors. Addressing these challenges and designing unbiased systems of care are essential to …

Scanning Electron Microscopy As A Potential Tool For Distinguishing Charcoal From Dark, Oxidized, Biomass, João Vitor Dos Santos, Aleksandar I. Goranov, Lais Gomes Fregolente, Joao Marcos De Lima-Faria, Diego Stefani Teodoro Martinez, Patrick G. Hatcher

Chemistry & Biochemistry Faculty Publications

Condensed aromatic carbon (ConAC) is widely used as a proxy for organic materials derived from biomass burning. However, recent evidence shows that ConAC can be also formed through nonpyrogenic oxidative processes. This study presents a proof-of-concept investigation using scanning electron microscopy (SEM) to distinguish charcoal from dark, ConAC-rich materials produced by ambient oxidation of biomass. Pine wood exposed to long-term iron-mediated oxidation was compared with unaltered wood and a controlled laboratory-generated charcoal reference. Conventional geochemical analytical methods, including benzenepoly(carboxylic acid) (BPCA) analysis, Fourier transform–ion cyclotron resonance–mass spectrometry (FT-ICR-MS), solid-state 13C nuclear magnetic resonance (NMR) spectroscopy, and elemental analysis, confirmed substantial …

The Economics Of The U.S. Student Loan Market And The Case For The Education Development Financial Institution, Ian Akers

CMC Senior Theses

The United States student loan market is shaped by a variety of market failures–credit constraints, positive externalities, behavioral frictions including myopia, debt aversion, and misperception–that together justify government intervention in the market. Yet the design of federal intervention is just as important as its existence. This thesis details the economic theory underpinning the market for student loans, evaluates three historical federal student loan programs (the Perkins Loan Program, the Federal Family Education Loan Program, and the Federal Direct Loan Program) through the lens of that theory. The thesis then proposes a novel institutional model as a targeted response to the …

Revenge Of The Interceptors? The Dod, Congress, And The Return Of Space-Based Missile Defense During Trump 45, Chad Mcelroy

CMC Senior Theses

The initiation of the Golden Dome for America program has brought space-based missile defense (SBMD) to the forefront of American national security policy and rekindled debates that had laid dormant since the administration of President Ronald Reagan. How, forty-two years after President Reagan first proposed the Strategic Defense Initiative, did SBMD return as a national priority? In lieu of public information about the ongoing Golden Dome initiative, this thesis explores the first Trump administration, otherwise known as Trump 45, in order to analyze the development of SBMD proposals by its proponents in Congress and the Department of Defense. I used …

The Evolution Of California Wildfire Governance Through State Bills, Regulations, And Executive Actions, Cassandra Dawn Blevins

History and Political Science | Senior Theses

California faces an escalating wildfire crisis, driven by climate change, drought, and development in fire-prone areas. Despite decades of scientific research on wildfire behavior and risk reduction, catastrophic fires since 2017 raise a critical question: to what extent have California state laws and policies kept up with the intensifying wildfire crisis? Existing scholarship provides extensive insight into wildfire ecology, land-use planning, fuel management, and community resilience, yet it lacks a comprehensive evaluation of whether California’s legislative, regulatory, and executive actions have adapted in a coordinated and evidence-informed manner. In particular, the literature offers limited analysis of how state laws integrate …

A Computational Approach To Graduated Centrifuge Profiles For Partial Gravity Planetary Environments, Cabell W. Jones

Mechanical & Aerospace Engineering Faculty Publications

Missions such as NASA’s Artemis and SpaceX’s Starship aspire towards creating permanent settlements beyond Earth. In order to achieve this goal, it must be considered that the gravity present on planetary surfaces such as the Moon (0.165 g) and Mars (0.378 g) may be insufficient to support human physiology for long term habitation. On near-Earth missions, issues such as muscular atrophy, neuro-ocular changes, cardiopulmonary variations, and bone mineral density loss have been observed proportional to the duration spent in microgravity. Further studies have suggested that the severity of these conditions scales linearly with decreasing gravity, meaning that astronaut health can …

Allocating Electricity, Alexandra Klass, Dave Owen

Articles

The U.S. electricity system is premised on the ideas that utilities have a duty to serve all customers in their service territories and that electricity supply should always meet demand. Until recently, there has been little reason to question these foundational premises. U.S. electricity demand has remained flat for over a decade, and during earlier periods of growth, new energy generation plants were relatively easy to build. Now, however, electricity experts predict massive load growth—most notably from data centers to power artificial intelligence and cryptocurrency—and building new power plants is no longer easy.

Major efforts are underway to increase electricity …

Investigating Policy Enactment In Community Sport Coaching: Directions For Future Research, Ben Ives, Dawn Penney, Jimmy O’Gorman, Adam J. Nichol, Paul Potrac, Lee Nelson

Research outputs 2022 to 2026

This article calls for a sophisticated investigation of policy enactment in sport-related environments, with community sport coaching used as an example case. Emphasis is placed on the need for in-depth empirical research into and theorisation of: 1) political skills involved in the enactment of policy; 2) emotion management when enacting policy; 3) performative and fabricated aspects of policy enactment; and 4) impacts of policy enactment for the health and wellbeing of workers. In doing so, this article challenges scholars to move beyond the study of policy actor types and to develop more nuanced understandings of the political, economic, organisational, interpersonal, …

Simulating Social Attitudes With Llms: Accuracy, Demographic Effects, And Refusal Behavior In The Sensitive Domain Of Suicide Prevention, Cristina J. Perez, Michael P. Vasquez Jr., Philippe J. Giabbanelli, Patrick Y. Wu

VMASC Publications

Large language models (LLMs) are increasingly used to simulate public opinion, yet their validity in sensitive policy domains remains underexplored. We evaluate whether LLMs can reproduce attitudes toward suicide prevention policies using 32 questions drawn from seven nationally representative U.S. surveys (2023-2025). We systematically vary demographic conditioning (race/ethnicity, gender, age, education, income, party), prompt framing (direct elicitation, respondent embodiment, specialist embodiment), and model architecture (GPT-5 Nano, DeepSeek V3.2, Meta Llama 3.1 8B, Mistral Small 24B). Across 811,560 prompts, the mean absolute error—the average gap between predicted and human response distributions—is 23 percentage points. We also find that LLM responses to …

Geography Of Erasure: Manufactured Housing, Heat Exposure, And State Neglect In Florida, Gianna M. Hutton

Pomona Senior Theses

This thesis examines Florida's manufactured housing communities through the intersecting frameworks of energy justice, critical heat studies, and housing displacement scholarship, centering how structural, political, and economic forces shape uneven exposure to thermal insecurity and housing precarity. Using a mixed-methods approach combining statistical regression analysis of American Community Survey microdata (2019-2023) and spatial case study of Miami-Dade County's heat governance and The Li'l Abner Mobile Home Community’s displacement, this research investigates how manufactured housing residents experience compounded exclusions across energy systems, urban heat governance, and housing security. The findings reveal that manufactured home residents face a 26% higher energy burden …

Left In The (Road) Dust: Analyzing Advanced Clean Cars Ii In California’S Disadvantaged Communities, Jj Hoffman

Pomona Senior Theses

Across the United States, air pollution disproportionately impacts minority groups. California’s Advanced Clean Cars II (ACC II) waiver was positioned to lead to significant environmental justice impacts, such as reductions in emissions and adverse health outcomes, by establishing stricter regulations for vehicle emissions and ensuring that 100 percent of new passenger vehicle sales are zero-emission by 2035. As the federal government recently nullified ACC II, pollution, and by extension health, could worsen, especially in disadvantaged communities. The thesis established several important relationships, including how disadvantaged communities experienced higher traffic, pollution, and worse health outcomes than non-disadvantaged communities. Though the results …

Sex, body mass index (BMI), and body fat % (BF% via circumference and an equation) were measured. Accelerometer PA and sedentary time were computed for IPAQ categories …

Rethinking Reentry In The United States: A Comparative Analysis Of Incarceration Strategies In Norway, Singapore, And Austria, Amelia Ulmer

CMC Senior Theses

The prison reentry system in the United States remains a pressing social, economic, and political issue, as hundreds of thousands of prisoners are released each year with few resources to assist them with their transition. In fact, these previously incarcerated people are arguably set up to fail, which leads to over half of them reoffending within two years. This thesis analyzes how the United States should reform its current prison system based on lessons learned from three international case studies. These three case studies, Norway, Singapore, and Austria were chosen as countries that have globally low recidivism rates and unique …

The Future Of U.S. Higher Education: Equity Implications Of Shifting Immigration Policies, Research Institute For Social Equity Rise

Research Institute for Social Equity

This report examines the impact of U.S. immigration policies on higher education and international students from 2000 to 2025. It traces five major policy eras, from the post- 9/11 security overhaul and Obama-era expansion to the restrictive turns of 2017–2020 and 2025, and analyzes how shifting regulations have influenced enrollment patterns, economic contributions, and student well-being. Despite hosting more than 1.1 million international students in 2023–2024, the U.S. share of the global student market has fallen from 20% to 16%, underscoring how policy volatility and restrictive measures weaken national competitiveness. Drawing on federal data, scholarly research, and institutional reports, this …

Collaboration And Co-Management Ahead Of Permitting: Understanding How Actors And Their Interactions Lead To Non-Optimal Shoreline Projects, Juita-Elena (Wie) Yusuf, Mariana Saitgalina, Michelle Covi

School of Public Service Faculty Publications

Living shorelines are widely promoted as nature-based solutions to coastal erosion and wetland protection, yet hardened shoreline structures continue to dominate even in jurisdictions with explicit policy mandates prioritizing living shorelines. In this research, we examine why non-optimal shoreline modification outcomes persist in Virginia (USA) despite a regulatory framework designed to promote ecological alternatives. We use primary data from interviews with wetlands board members, marine contractors, and nonprofit organizations and findings from a secondary survey of shoreline property owners to analyze shoreline management as a multi-sector collaborative decision-making process. Findings show that shoreline outcomes are shaped less by individual regulatory …

Public Perception Of Environmental Contamination And Its Implications For Fish And Community Health In West Bengal, India, Libia Hazra

Dissertations, Master's Theses and Master's Reports

In West Bengal, India, the highest fish-consuming state in the country, fish are woven into everyday life, including ceremonies of birth and marriage, prayers offered during harvesting and the cultural memory of communities whose identities are inseparable from aquatic life. However, the rivers, wetlands, and ponds that sustain these fish-human relationships are increasingly threatened by environmental contamination resulting from industrial discharge, agricultural runoff, and inadequate environmental management. Understanding how communities perceive these environmental changes is essential for developing effective conservation and public health strategies.

In collaboration between the Indian Institute of Technology (ITT) Kharagpur, India, and Michigan Technological University (USA), …

The Political Economy Of Pfas Treatment And Water Regionalization In Harrison County, Kentucky, Jackson S. Patru, Rajan Sampat

MPA/MPP/MPFM Capstone Projects

The discovery of per- and polyfluoroalkyl substances (PFAS) in the water supply of Harrison County, Kentucky has prompted an urgent reevaluation of local treatment infrastructure. This situation has exposed a complex political economy between the City of Cynthiana, which owns and operates the municipal water plant, and the Harrison County Water Association (HCWA), which represents the majority of the ratepayers supplied by the plant. Using a qualitative research design grounded in inductive thematic analysis, semi-structured interviews were conducted with leadership from both Cynthiana and HCWA, as well as operators at the treatment plant, to evaluate two proposed solutions: a $14 …

Kentucky Space Futures: Defining The Driving And Limiting Factors Of Growth In The State Aerospace Industry, Ashley M. Grospitch, Isabella A. Sibold

MPA/MPP/MPFM Capstone Projects

Kentucky’s aerospace industry has quietly become one of the state’s most significant economic drivers, generating almost $19 billion in exports in 2024 and ranking third nationally in aerospace exports in 2023 (Mattingly, 2025; Babbage & Hartsough, 2024). Despite this, Kentucky remains largely invisible as an aerospace state, both to Kentuckians and national audiences. This work was conducted on behalf of our client, Kentucky Space Futures, to identify the factors shaping the growth of Kentucky’s aerospace industry, including its driving and limiting factors, and provide actionable guidance for policymakers and industry leaders.

Using a qualitative research design, this study triangulated findings …

Shrines On Asphalt Shoulders: Documenting Roadside Memorials In Western U.S. Roadscapes, Isabella R. Sullivan

Scripps Senior Theses

This thesis analyses the practice of documenting and uploading roadside memorials in the Western United States as a socially transformative process facilitated between two distinct kinds of noticing. Drawing on (auto)ethnographies of roadside memorial sites in Colorado and California, interviews with photographers and cartographers working primarily in the American Southwest, and Google Street View media, this research examines how recognition of the social negotiations involving memory and mortality that are already present in the physical shrines evolves when documenters capture and transpose them online. First, these documenters have developed the “eyes to see” roadside memorials for various significant reasons in …
