Building Fiscal Resilience And Enhancing Social Equity In Disaster Mitigation At The Local Level, Hyoeun Kim

Electronic Theses & Dissertations (2024 - present)

As climate-related disasters are becoming more frequent and severe, local governments face growing pressure to manage disaster-related fiscal shocks. Although disaster mitigation and preparedness are widely recognized as cost-effective strategies for reducing future losses, local governments often lack the financial, political, and technical capacity to invest in them. Despite the importance of pre-disaster investment, mitigation and preparedness efforts continue to lag at the local level, and concerns remain that federal mitigation funding is not distributed equitably across communities. This has important implications for both equity and resilience because unequal access to mitigation resources can reinforce existing vulnerability to future natural …

From Deference To Dialogue: How International Gtas From High Power Distance Cultures Adapt To U.S. Classroom Dynamics, Deborah Akua Afi Appiah

Theses and Dissertations

International graduate teaching assistants (GTAs) from high power distance cultures play a significant role in undergraduate education at U.S. universities, yet they face challenges that go well beyond language proficiency. Coming from educational backgrounds where teacher authority is unquestioned and hierarchical, these GTAs must navigate American classrooms that operate on fundamentally different assumptions, where authority is earned rather than assumed, informality is the norm, and students expect to question, negotiate, and be personally known by their instructors. The present study examined how eighteen (18) international GTAs from seven (7) high power distance countries perceived and adapted to these differences while …

Towards Supporting Real-Time Estimation Of Vehicle Fuel Consumption And Co2 Emissions In Smart City Applications, Abrar Alali, Stephan Olariu

Computer Science Faculty Publications

This paper evaluates a simplified physics-based energy demand model designed to estimate vehicle fuel consumption and CO₂ emissions—a critical tool for sustainable transportation planning and smart city applications. Unlike data-driven regression models that lack generalizability for user-defined conditions or complex physics-based approaches that rely on extensive, often proprietary data, the simplified model is distinguished by its minimal parameter requirements, depending primarily on a single, overarching powertrain efficiency value. A key contribution is the comprehensive empirical evaluation of the simplified model against official Environmental Protection Agency (EPA) test data across multiple driving cycles and vehicle types, providing a rigorous validation previously …

Improving Evacuation Effectiveness On Cruise And Large Passenger Ships : An Analysis Of Human Factors, Safety Culture, And Behavioral Dynamics, Antonios Andreadakis

World Maritime University Ph.D. Dissertations

Maritime trade has long constituted a central pillar of economic development, supporting global commerce and cultural exchange. Nevertheless, the maritime environment is inherently hazardous and therefore the protection of human life has consistently constituted and will continue to remain a central priority (Casson, 1995). An instrumental turning point in maritime safety occurred after the sinking of Titanic in 1912, which prompted in 1914 an International Conference dedicated to the protection of human life at sea; which ultimately led to the adoption of the International Convention on Safety of Life at Sea (SOLAS) (Dalaklis, 2017). This Convention introduced internationally imposed safety …

Biosecure-Llm Framework: Protecting Llms From Cyberbiosecurity Threats And The Case For Independent Ai Safety Governance, Xavier-Lewis Palmer, Lucas Potter, Srdjan Lesaja, Sotirios Karathanasis, Mohammad Ghasemigol

Computer Science Faculty Publications

Large Language Models (LLMs) are becoming critical infrastructure in scientific, healthcare, and governmental contexts. As frontier AI laboratories increasingly partner with government agencies, a fundamental question arises: Who should control the safety and policy-enforcement layers that constrain model behavior? Current safety mechanisms (LLM guardrails) are typically designed for generic "harmlessness" and operate by detecting semantic patterns and refusing requests. However, they are inadequate governance instruments because they cannot implement auditable, domain-specific controls tied to external regulatory policy objects (e.g., control lists or rules governing personally identifying information). Even a perfectly aligned model is not able to express institution-specific policy without …

The Influence Of Scale In Modeling Social Vulnerability And Disaster Assistance, Sina Razzaghi Asl, Oronde Drakes, Eric Tate, Samuel Brody, Wesley Highfield, Kayode Atoba

Political Science & Geography Faculty Publications

Understanding how social vulnerability relates to disaster impacts is critical for addressing social equity, yet the role of spatial scale in this relationship is often overlooked. Most studies use aggregated data, risking ecological fallacy-misinterpreting individual outcomes from group-level data. This study examines how spatial scale influences the relationship between social vulnerability and federal disaster assistance after Hurricane Harvey. Using spatial econometric models at both household and census tract levels, we assessed the strength of key vulnerability indicators in explaining disaster assistance. Results show that disability, housing tenure, household size, and income predict assistance at the household level, but their influence …

Nuclear Deterrence And The Security Dilemma In A Complex Multipolar World, Chick Edmond

Political Science & Geography Faculty Publications

Objectives: The purpose of this research project is to examine how nuclear deterrence intersects with the concept of security dilemma, i.e., when a state takes an action intended to increase its own security it may inadvertently create a risk or threat to another state and contribute to increased levels of tension. Fourth, how nuclear and conventional systems are becoming increasingly interconnected, which will serve to potentially amplify risks associated with these systems.

Methods: Utilizing a qualitative analytical approach of documents such as national strategy documents, defense policy statements and historical records of crises dating from 1945-2025, the study identifies four …

Autonomous Weapons And Strategic Stability, Chick Edmond

Political Science & Geography Faculty Publications

The increasing number of artificial intelligence (AI) elements within military systems has introduced new forms of security dilemmas related to speed, level of secrecy, and transfer of responsibility from humans to machines. This article addresses the question of whether or how AI enabled autonomous weapons can lead to greater levels of strategic instability. Three causal mechanisms were determined by this study to potentially create destabilizing effects due to the introduction of autonomy; the first mechanism is a reduction in time available for decision making. The second mechanism involves the creation of multiple pathways of escalation. The third mechanism is the …

Global Evidence On Scaling Nature-Based Solutions For Compound Hazards, Sina Razzaghi Asl, Anahita Azadgar

Political Science & Geography Faculty Publications

Nature-based solutions (NbS) are increasingly promoted for climate adaptation to compound hazards, but systematic evidence of their effectiveness is still scarce. We address this gap with a systematic review of 38 studies. Each study was sorted by what its measurement design can support, not by what its authors claim. This produced four groups. Direct studies attribute a measured hazard reduction to the intervention, proxy studies infer protection from ecosystem condition, prioritization studies map suitable locations without estimating performance, and qualitative studies describe effectiveness without measuring it. We detect trends in geographic distribution, hazard combinations, intervention types, methodological approaches, and strength …

Fear, Memory, And Deterrence: Reassessing Nuclear Peace In The 21st Century, Nathan H. Schroeder

Williams Honors College, Honors Research Projects

This research investigates the paradox of nuclear peace theory: the idea that nuclear weapons, despite their destructive capacity, have contributed to a more stable global order. By tracing the historical development of nuclear arsenals and the strategic logic of deterrence, the project examines whether the post-1945 decline in large-scale wars between superpowers and wartime deaths can be attributed to the threat of mutual annihilation. It also explores the psychological and cultural consequences of this deterrence-based peace, including the normalization of fear and its potential link to desensitization toward violence in younger generations. From Cold War-era school drills to modern apocalyptic …

Immigration Securitization And Educational Access: The Impact Of U.S. Immigration Policy On International Students, Cossir Carter

Honors Undergraduate Theses

This study examines the securitization of international students within the broader transformation of United States immigration policy from the post-9/11 era to the present administration. Following the September 11 attacks, immigration governance was increasingly reorganized under a national security framework, significantly altering the regulatory environment surrounding student visas. Subsequent policy shifts have intensified monitoring mechanisms and administrative controls that directly shape international students’ access to education and mobility. Given the sensitivity of immigration-related participation in the current political climate, this research employs qualitative policy analysis rather than direct student surveys. Under the Trump administration, this securitization intensified through stricter visa …
