Measuring Multimodal Equity In Resource-Challenged Mpos, Christopher Ferrell, David Reinke, John M. Eells

Mineta Transportation Institute

Ensuring transportation investments are equitable across different populations and travel modes is a priority for many agencies, yet existing tools often make these assessments difficult, especially for smaller and resource-constrained organizations. To address this gap, this report provides the findings of Phase II of our study on reviewing and developing transportation equity metrics. The Phase I project investigated transit equity metrics and provided recommendations on advancements in quantitative methods. Building on Phase I recommendations, this study investigates low-cost methods for comparing the equity between auto (roadway) and transit performance or investments for low resource transportation agencies. A literature review revealed …

U.S. Arctic Sea Lines Of Communication (Sloc): The Imperative For A Maritime Complex And Corridor In The Bering Region, Samuel A. Krakower, Troy J. Bouffard

Joint Force Quarterly

This paper examines the current American capacity to defend its newfound Sea Lines of Communication in the North Pacific and Arctic Oceans. The history, and importance, of Sea Lines of Communication trace back to great naval strategists such as Rear Admiral Alfred Thayer Mahan and Sir Julian Corbett, and consistent protection of these maritime corridors in times of war and peace led to the success of the United States. As the Arctic Region emerges as a new theater of geopolitical importance, the United States finds itself significantly disadvantaged or "strategically handicapped” in terms of presence, capability, and proximity to defend …

Simulating Cyber-Resilience: The Strategic Role Of The Locked Shields Exercise In Enhancing International Cyber Preparedness, Christopher A. Ramezan, Ludwig Christian Schaupp, Elizabeth A. Vitullo, William J. Walker

Journal of Cybersecurity Education, Research and Practice

As cyberthreats to critical infrastructure remain prevalent, national response mechanisms must evolve beyond the technical domain to incorporate legal, communicative, strategic, and cross-sector coordination. This work explores Locked Shields, an annual exercise conducted by NATO's Cooperative Cyber Defence Centre of Excellence, as a pedagogical and conceptual framework for simulating whole-of-government responses to cyber incidents. Unlike traditional cyber exercises, Locked Shields engages legal advisors, media strategists, and civil-military roles in realistic, scenario-driven simulations that portray the political and operational conditions of a real international-scale cyber crisis. We detail the exercise architecture, contrast with other cyber exercises, and assess its pedagogical and …

Assessing Public-Sector Readiness For Artificial Intelligence In Egypt, Renad Ahmed Anwar

Theses and Dissertations

Artificial intelligence (AI) is increasingly adopted in public-sector contexts, yet successful implementation depends on organizational readiness, particularly in developing countries. This study assesses the readiness of Egypt’s public sector for AI adoption using a qualitative expert opinion methodology. Semi-structured interviews were conducted with senior professionals from global technology firms with extensive experience working with public-sector entities in Egypt.

Guided by by an integrated framework combining organizational readiness theory, the Technology–Organization–Environment (TOE) framework, and public value and governance perspectives, the study examines strategic, organizational, human, technological, societal, and governance dimensions of AI readiness. The findings indicate that while Egypt demonstrates strong …

A Policy Reversal As Structural Break: A Lesson From China’S Land Lease Financing For Infrastructure, Yilin Hou, Lin Li, Lei Shao

Center for Policy Research

Land-based revenues as a fiscal instrument to finance infrastructure tie public investment to real estate markets, where demand fluctuations cause fiscal consequences. This paper takes policy reversals as structural breaks and examines their impacts on infrastructure investment. We dissect China’s 2016 policy reversal that disallowed developers to finance land purchase with debt, causing sharp declines in local government land revenues, slashing their fiscal base for infrastructure investment. Using prefecture-level panel data and continuous difference-in-differences identification, we estimate the reversal reduced land-lease revenues by 55%. Two-stage least squares estimates suggest a 10% land-revenue decline translates into 6.6% investment reduction. Decomposing the …

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 …

Institute for Sustainable Energy and Environment Publications and Presentations

This report examins the extent of air pollution emissions resulting from the use of backup generators at data centers in Northern Virginia, including both actual current emissions and potential future emissions, and how those emissions totals compare to other sources of air pollution in the Northern Virginia region. It also examines how exposure to data center emissions correlates with demographic characteristics such as race, income, and education.

We while the air pollution emissions from individual data centers is minor, the collective impact from the 100+ such facilities in the Northern Virginia region is significant. Notably, the cumulative emissions exposure in …

No Coup, No Conscience: Coup-Proofing In The Armenian Genocide, Rachel Svoyskiy

CMC Senior Theses

The Armenian Genocide functioned as a form of coup-proofing under the Committee of Union and Progress (CUP). Existing scholarship emphasizes nationalism, wartime radicalization, and security dilemmas, but does not fully account for why the military complied, why dissenters were removed, or how Armenian property became tied to political loyalty. Applying Hicham Bou Nassif’s framework of coup-proofing, this study examines four tactics the CUP used to secure military obedience while carrying out mass violence. First, the regime framed Armenians as an existential threat to align the officer corps ideologically with the state. Second, it promoted the material interests of military and …

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 …

Diagnosis And Proposal For Addressing The Depopulation In Northern California Towns, Cahal T. Connolly

CMC Senior Theses

This thesis examines population decline in small Northern California towns as a process of functional depopulation. Demographic loss becomes most damaging when it weakens the institutions that make communities livable. Focusing on rural towns facing aging populations, economic contraction, climate risk, housing instability, and service erosion, the thesis argues that sustainability cannot be measured by population change alone. Instead, towns must be evaluated according to their ability to maintain municipal services such as schools, healthcare, emergency services, infrastructure, local governance, and civic life. The thesis develops a stabilization framework that distinguishes among stabilizable, transitional, and structurally declining communities based on …

Florida Local Public Administrator Perspectives On Decentralized Wastewater Treatment, Jude Hagan

Honors Undergraduate Theses

Decentralized wastewater treatment (DWT) systems, such as onsite greywater recycling and septic systems, have been demonstrated to be a potentially more sustainable, cost-effective, and disaster-resilient alternative to traditional centralized systems by treating wastewater at or near the source. However, many barriers exist that have prevented the widespread implementation of DWT, such as public opposition, lack of resources, government regulations, public health concerns, and capital costs. In this study, local emergency managers, urban planners, and utility/wastewater managers in Florida were surveyed to determine their perceptions and levels of knowledge on DWT. The results of this study were inconclusive due to a …

Evidence-Based Policymaking And Global Governance: An Examination Of The Role Of The Policy Studies Organization And Ecosoc, Chick Edmond

Political Science & Geography Faculty Publications

Transnational challenges, such as climate change, global inequality, pandemics, digital governance, and institutional legitimacy crises, are becoming increasingly complex, therefore, the demand for evidence-based decision-making has become an important developing normative and practical issue in the area of global governance. The Economic and Social Council (ECOSOC) is the principal organ of the UN responsible for coordinating policy processes across all areas of economic, social and development issues. However, despite ECOSOC’s ability to make decisions concerning how the world addresses these problems, it has been widely criticized for being unable to translate expert knowledge into tangible policy outcomes. Therefore, this paper …

Analysis Of Policies And Incentives For The Successful Implementation Of Hydrogen-Fueled Medium-Duty And Heavy-Duty Vehicles In Humboldt County, California, Alka Verma

Cal Poly Humboldt theses and projects

The 21st century has seen a significant rise in global greenhouse gas (GHG) emissions, with the transportation sector contributing 23% of these emissions. Medium-duty and heavy-duty vehicles (MD/HD) are particularly impactful, accounting for over a quarter of transport-related emissions. In Humboldt County, California, transportation represents 53% of total emissions, with MD/HD vehicles being a major contributor. As light-duty vehicles shift to zero-emission alternatives, the MD/HD sector faces unique challenges. Hydrogen fuel cell vehicles offer a promising solution, providing longer range, higher energy density, and quicker refueling compared to battery electric vehicles (BEVs). These features make hydrogen an attractive option for …

Interpretable Machine Learning For Bridge-Pier Scour Prediction And Flood Resilience, Adil Khan, Dalya Ismael

Engineering Technology Faculty Publications

Bridge-pier scour is a leading cause of flood-induced bridge failure, yet practice still lacks transparent, physics-informed tools that link data-driven prediction with design guidance. This study develops an interpretable, physics-aware machine-learning framework to predict equilibrium scour depth and translate those predictions into actionable strategies for flood-resilient infrastructure. Using the 2014 U.S. Geological Survey Pier-Scour Database (569 laboratory cases), five models: Gradient Boosting, AdaBoost (Tree), XGBoost, Gaussian Process (RBF kernel), and Kernel Ridge (polynomial), were trained and evaluated with K-fold cross-validation. Model performance was evaluated using R², RMSE, and MAE. Gradient Boosting performed best, achieving training and testing R² of 0.99 …
