Opportunities For Urban Resilience To Climate Change: Understanding Local Climate Perceptions, Motivations, And Barriers To Green Infrastructure Use, Emmilene Berski

Department of Geography: Dissertations, Theses, and Student Research

Global climate change poses a substantial threat to cities in the United States, particularly through increases in flooding and extreme heat. Cities must adapt to these threats to preserve their residents’ livelihoods and prevent economic loss. One adaptation strategy is the implementation of green infrastructure (GI). The opportunity for GI to foster urban resilience to climate change necessitates a deeper understanding of the extent to which cities utilize GI as a strategy for local climate change adaptation as well as perceptions and motivations surrounding the use of GI at a local level. I sought to address this need through a …

Does California High-Speed Rail Promote Accessibility For Station Cities?: Case Study Of Fresno And Merced, Chih-Hao Wang, Na Chen

Mineta Transportation Institute

California High-Speed Rail (CHSR) will largely change transportation cost across the state after it starts operating. Past studies show that only Fresno and Merced among station cities in the Central Valley would attract more future activities with the CHSR. The establishment of active CHSR also implies a new daily living sphere for all the station cities, and, therefore, accessibility to work and residential amenities should be reviewed to inform planners of future land-use and transportation developments. A research framework has been developed better to understand the impact of CHSR on job and amenity accessibility by driving, transit, and walking in …

Using The State-Reinforced Self-Governance Framework To Evaluate Neighborhood Revitalization In The Choice Neighborhoods Initiative., Gifty Amma Adusei

Electronic Theses and Dissertations

Scholars and planners advocate for neighborhood revitalization programs that prioritize inclusive planning and partnership with indigenous residents. Such planning must derive its vitality from residents’ leadership and legitimatize citizens as full partners and collaborators. Over time, the U.S. federal government's approach to neighborhood distress has shifted from top-down approaches towards inclusive revitalization planning. Despite advancements, concerns persist about the sustainability of revitalization outcomes through initiatives like the most recent federal revitalization effort, Choice Neighborhoods Initiative (CNI). The dissertation project begins from the premise that when governments effectively support co-production (a complementary, synergistic relationship between different groups working together as equal …

A Red Awakening: An Analysis Of China’S Quest For Global Dominance Through Economic Alternative Warfare Methods, Sarah Beddingfield

Senior Honors Theses

In the 2023 annual meeting of China’s parliament, Chinese President Xi made it clear to his political leaders and the world that he was preparing for war. This should come as no surprise after analysis of China's grand strategy points clearly to the intent to surpass the U.S. as the premier global superpower in all respects. China has been building towards this goal for years through untraditional methods of warfare, forcing the national security community to reevaluate its own strategy and assess the Chinese threat through a different lens. This thesis seeks to address one specific area in which China …

Risk Perception, Dread, And The Value Of Statistical Life: Evidence From Occupational Fatalities, Perry Singleton

Center for Policy Research

In a model of occupational safety, biased perceptions of risk decrease welfare, which may justify government regulation. Bias is examined empirically by the correlation between subjective and objective risk, the former measured by self-reported exposure to death on the job. The correlation is negligible among workers with no high school diploma, consistent with underestimating risk in more dangerous occupations, and strongest among more educated workers when objective risk is specific to harmful and noxious substances, which in psychological studies rank high in dread. Biased perceptions of risk may also lead to biased estimates of value of statistical life. VSL estimates …

State Policies On Maternal And Infant Health In The United States, Heeun Kim

Legacy Theses & Dissertations (2009 - 2024)

In the United States (US), state-level policies are critical structural determinants of maternal and infant health outcomes. State policies profoundly affect prenatal care utilization and pregnancy outcomes, particularly among marginalized pregnant persons with stigmatized health conditions. In this three-paper dissertation, I focus on two closely interrelated policies that aim to address significant public health concerns in the US: prenatal syphilis screenings and the criminalization of prenatal substance use. My research revolves around two central questions: First, do these policies effectively improve the pregnancy outcomes of high-risk populations, or do they cause unintended consequences? Second, if challenges in policy design and …

How Regional Innovation Networks Are Governed: Three Essays On The Roles Of Network Management In Network Effectiveness And Evolution, Beomgeun Cho

Legacy Theses & Dissertations (2009 - 2024)

Although a networked mode of governance has been often considered as an alternative or superior approach compared to hierarchy and market-based models, it has become clear that networks are also susceptible to failure without purposeful and deliberative management of interorganizational relationships. Constructing a longitudinal dataset of 16 regional innovation networks in South Korea, this dissertation examines how Regional Public Research Institutes (RPRIs) serve as network managers who initiate, facilitate, and mediate regional innovation systems. Drawing on a network research tradition rooted in the Dutch School of governance networks, this study examines how RPRIs leverage social structural resources, originating from their …

Upstream Local Actor And Community-Based Potential In Mass Atrocity Prevention, Numa R. Khan

ALL - Honors Theses

The concept of genocide and mass atrocity prevention is still relatively new. Research on genocide prevention would not begin until post 1995 following the genocides in Rwanda and the former Yugoslavia (Rosenberg & Zucker, 2015). Therefore, there is much left to be uncovered in the field (Rosenberg & Zucker, 2015), despite that genocides and mass atrocities have occurred for centuries prior to the coining of the term and continue to occur to this day (Bellamy, 2015).

The term genocide falls under atrocity crimes, an umbrella term that refers to genocide, crimes against humanity, war crimes, and occasionally ethnic cleansing (United …

Towards Sustainable Development: Civic Architecture As Material Banks, Kathleen O'Gara

Masters in Architecture Program: Theses

This thesis posed the question, “How can buildings be designed to be disassembled and reused to reduce construction and demolition waste and reduce our unsustainable reliance on raw materials?” Designing for disassembly and reuse has the potential to dramatically increase the life of building materials, thus decreasing construction and demolition waste relating to architecture. When designing with deconstruction and reuse in mind, designers must consider the next life of these materials. The thesis was further narrowed to push the adaptability of these materials by designing a structural kit of parts. The structure system is often seen as a stable and …

Residents’ Perceptions Of Use On Community Interface Areas At Protected Areas’ Boundaries: A Comparison Between Users And Non-Users, Louis Santiago Brevan

All Theses

Over the past fifty years, Protected Area (PA) management has gradually transitioned from the traditional top-down approach toward a more collaborative and participatory management model, which integrates the needs and perspectives of local communities. This quantitative study used a questionnaire to assess the perceived constraints of visitation, the attitudes toward tourism development, and the level of involvement in decision-making among community members residing near a community interface area on a PA’s boundaries. Structural constraints were the most prominent barrier to visiting (i.e., the poor state of the road and facilities). Residents indicated strong support towards tourism development and nearly half …

Outcome Measures Or Graduation Rates, That Is The Question, Miran Kang

Graduate Theses and Dissertations

The study compared the Outcome Measures (OM) to the traditional Graduation Rates (GR) to ascertain if OM portrayed the performance of higher education institutions differently than GR and to determine which of the two metrics aligned better with accountability policy objectives. GR refers to the percentages of first-time, full-time students who obtain a degree or certificate within 150% of the normal time. OM presents the award status of all degree/certificate-seeking undergraduate students on four cohorts: first-time, full-time (FTFT); first-time, part-time (FTPT); non-first-time, full-time (NFTFT); and non-first-time, part-time (NFTPT). OM was a more comprehensive indicator than GR, particularly for 2-year institutions, …

Inclusive Policy, Diverse Perspectives: Affirmative Action And The Model Minority Among University Students, Jannie Nguyen

Honors Theses

In lieu of the recent Supreme Court overturn of affirmative action, Asian American students were on the forefront as the main racial group defended in this case.

Polarimetric Radar Signatures In Significant Severe Left-Moving Supercells, Raychel Nelson

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Left-moving (LM) supercells, though rarer than right-moving (RM) supercells, may produce significant severe weather. However, there are very few existing studies on LM supercells, particularly polarimetric radar analyses. The upgrade of the nationwide Weather Surveillance Radar-1988 Doppler (WSR-88D) network to polarimetric capability and subsequent studies vastly improved understanding of RM supercells, but similar efforts have largely not been made for LM supercells. This study employs an automated polarimetric radar signature detection algorithm to examine a dataset of significant severe (hail ≥ 2.00”, wind ≥ 65 kts) LM supercells to quantify their polarimetric signatures. Comparisons are made with RM supercells to …

A Dual-Polarimetric Analysis Of A Large Sample Of Left-Moving Supercells, Ben Schweigert

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Supercells have been researched extensively since they were first described over 50 years ago. They are prolific severe weather producers, responsible for the most severe hail, severe wind gusts, and tornadoes. These rotating thunderstorms require attention from forecasters to protect life and property from their threats, most effectively done with Doppler radars. While extensive amounts of radar-based investigations have been completed, they focused almost exclusively on right-moving (RM) supercells, resulting in a knowledge gap surrounding their counter-rotating (left-moving, LM) partners. This study works to fill the void by developing a dataset of LM supercells and analyzing the dual-polarimetric features observed …
