Assessing The Co-Benefits Of Housing And Transportation Investments In Prohousing Designated Jurisdictions, Hongwei Dong

Mineta Transportation Institute

In response to California's ongoing housing affordability crisis, state and local governments have adopted a range of prohousing policies aimed at reducing barriers to housing production and promoting the integration of housing with transportation. This study examines two distinct but related dimensions of prohousing policies in California. One concerns the Prohousing Designation Program (PDP) (established by the 2019–2020 Budget Act), analyzing the adoption and implementation of prohousing policies in 56 California cities that received Prohousing Designation. The other examines recent state and local policy shifts aimed at promoting affordable housing in transit-rich areas. The study uses a mixed-methods research design, …

Vision With Grace: Intersectionality Of Education And Spirituality, Preeti Jha

Dissertations

Contemporary educational leaders face increasingly complex challenges, systemic inequities, educator burnout, and demands for transformation, yet existing leadership frameworks fail to address the inner lives and spiritual practices that sustain such demanding justice work. While research demonstrates spirituality's role in leadership effectiveness, this dimension remains largely unexplored in educational research, particularly regarding how spiritual consciousness shapes daily practices and social justice engagement. This qualitative study will examine how spirituality shapes educational leadership and social justice engagement through portraiture methodology and in-depth interviews with three spiritually aligned educational leaders in Northern California. Drawing upon the Bhagavad Gita, Spiritual Leadership Theory, and …

Advancing Clean Mobility: Hydrogen Fuel Cell Electric Bus Workforce Development For Transit Agencies, Manideep Tummalapudi, Shantanu Kumar, Jaskaran Singh

Mineta Transportation Institute

Hydrogen fuel cell electric buses (FCEBs) are rapidly transforming public transportation in the United States. However, while transit agencies are investing heavily in new zero-emission vehicles and fueling infrastructure, far less attention has been paid to the workforce needed to operate and maintain them. As agencies accelerate toward ambitious climate and fleet transition goals, they are also confronting a critical challenge: preparing workers for an entirely new set of technologies, safety requirements, and operational demands. This study addresses that gap by systematically identifying the knowledge, skills, and abilities (KSAs) required for FCEB vehicle operators and maintenance technicians, assessing current training …

Pushed To The Edges? Electivity Patterns Of Urban Stream Homeless Encampments In Environmentally Burdened Areas, Serena Alexander, Bennett Williamson, Jeff Wootton, Costanza Rampini, Gregory Brian Pasternack, Yufang Jin, Rune Storesund, Igor Lacan

Faculty Research, Scholarly, and Creative Activity

Urban stream corridors in the San Francisco Bay Area have increasingly become locations for homeless encampments, yet little is known about the environmental conditions of these spaces. This study uses a geospatial electivity index to examine whether urban stream encampments in Santa Clara and Contra Costa counties are disproportionately located in census tracts with high pollution burdens, as measured by CalEnviroScreen 4.0. Findings show a statistically significant overrepresentation of encampments in census tracts in the top 25% of pollution and vulnerability scores, and a significant underrepresentation in lower-pollution areas. These results suggest that homeless individuals are being pushed toward environmentally …

Teaching China Beyond Eurocentrism: Intercultural Pedagogy And The Case Of The República Del Reino De La China By Jerónimo Román Zamora, Miriam Diaz Belizon

Comparative Philosophy

Interdisciplinary approaches to teaching China in Western academic contexts often reproduce Eurocentric frameworks that reduce Chinese philosophical and cultural traditions to subordinate objects of analysis. This article proposes an alternative model grounded in intercultural philosophy and the Filosofías del Sur, arguing that China should be approached not as a distant object of representation, but as an epistemic interlocutor capable of transforming philosophical education. The article develops this argument through the recovery of the República del Reino de la China, included in the 1595 edition of Repúblicas del Mundo, as a key example of early intercultural mediation from the European South. …

Timelines Over Tokens: Summarization, Prompting, And Explainable Fine-Tuning For User-Level Suicide Risk Detection, Aditya Tekale

Master's Theses

This research presents a two-stage pipeline for user-level suicide risk detection from Reddit: first, inference-only prompting with summarization; second, fine-tuned encoder classification with explainability and expert validation. The data are user-level: each of the 500 C-SSRS Reddit items is one user’s chronologically concatenated posts and comments (a user timeline), annotated by psychiatrists. Stage one: six prompting strategies zero-shot, few-shot, chain-of-thought, tree-of-thought, least-to-most, and self-consistency are evaluated across six LLMs on multi-class and binary formulations; simple zero-shot achieves the highest balanced accuracy (0.53 multi-class). Error analysis shows longer inputs associate with misclassification (p = 0.002); domain-specific summarization (timelines >2,000 tokens) reduces …

Spatial Heterogeneity And Temporal Trends Of California Extreme Heat Using High-Resolution Earth System Model Simulations, Eleni Konstantelos

Master's Theses

Extreme heat threatens California’s diverse landscapes and populations through intensifying and geographically shifting patterns. This study examined the temporal trend and spatial heterogeneities of California’s extreme heat for 1994–2015. The analysis was based on the fully coupled Energy Exascale Earth System Model version 2 (E3SMv2), specifically its 25-km regionally refined configuration. While the Desert/Inland region exhibited the highest number of days ≥ 35 °C and the highest heatwave severity, Central Valley showed the fastest increase in the number of days ≥ 35 °C and heatwave events, as well as the fastest increases of days exceeding various heat index thresholds over …

Safe, Secure, And Affordable? The State Of Household Water Insecurity In California, Melissa Beresford, Wendy Jepson, Jeremiah Osborne-Gowey, Kristin Dobbin, Amanda Fencl, Silvia R. González, Gregory Pierce

Faculty Research, Scholarly, and Creative Activity

California's efforts to advance the Human Right to Water are constrained by limited household-level data on water insecurity. Using the 2021 CalSpeaks statewide probability survey (n = 628) this study offers the first representative look at water insecurity across California households. Results reveal significant water-related struggles: approximately 23% of respondents worried about having enough water to meet their household needs, 15% worried about perceived health impacts from water quality, and 7% struggled with affordability. Negative binomial regression models show that water insecurity is not randomly distributed: households with non-white residents, households which rely on private or small water companies for …

To enhance hydrologic modeling, the hydrology community has developed benchmark datasets (e.g. Model Parameter Estimation Experiment, MOPEX), providing standardized data for model evaluation and parameter estimation. However, these datasets primarily focus on modeling natural hydrologic processes, leaving a critical gap in understanding the role of human influences. Here, we introduce the Coupled Hydrology-Human Activity Information (CHHAI) dataset, a benchmark dataset that integrates coupled human–water data from regions across all continents, excluding Antarctica. CHHAI incorporates data from 25 regions that cover various human impacts such as reservoir management, flood protection, river management policies, land use changes, and water use. Each basin …

Routes To Sustainable Goods Movement: How Local And Regional Governmental Agencies Can Plan For The Sustainable Freight System Of The Future, Serena E. Alexander, Avante Grady

Mineta Transportation Institute

Freight transportation plays a critical role in supporting economic activity and everyday consumption across metropolitan regions, but growing freight demand continues to increase congestion, infrastructure strain, greenhouse gas emissions, air pollution, and safety risks. These impacts often disproportionately affect low-income and environmentally burdened communities. This report examines how metropolitan regions across the United States are planning for sustainable freight transportation through content analysis of freight and goods movement plans and interviews with freight planning professionals. The study analyzes plans from eight major metropolitan regions to identify common freight planning strategies, implementation approaches, opportunities, and barriers related to sustainability, resilience, and …

System Branding In Three Public Libraries: Live Oak Public Libraries, Charlotte Mecklenburg Library, And Richland Library, Patrick Roughen

Library Philosophy and Practice (e-journal)

This article examines library catalogs as brand artifacts in the context of two ancient libraries: the Library of Alexandria and the library of the Temple of Horus at Edfu, Egypt. Drawing on Pierre Bourdieu’s concept of symbolic capital and brand theory, this research argues that the catalogs of these two institutions functioned as early branding instruments. The Pinakes, the catalog of the Library of Alexandria, projected a brand of universal knowledge and intellectual prestige, and the inscribed wall catalog at Edfu reflected a brand focused on sacred authority and the sustaining of cosmic order (Ma'at).  Together, they illustrate two opposing …

Chromolaena odorata is a dominant pioneer species in the successional vegetation following deforestation in humid and sub-humid tropical regions. Despite its prevalence, the specific interactions between C. odorata and subsequent food crops remain poorly characterized. This study aimed to evaluate the influence of C. odorata on the growth and yield of maize (Zea mays L.) under varying nutrient regimes. The experiment employed a randomized complete block design to assess the interaction between shrub presence (present vs. absent) and fertilization (0 or 1× the recommended N–P–K rate). The results indicated that the presence of C. odorata significantly increased maize height, stem …

The Caspian Sea, the Earth's largest inland water body, faces water level decline, drawing comparisons to the collapse of the Aral Sea. Unlike the Aral Sea, the relative roles of climatic variability, hydrological changes, and anthropogenic pressures on the Caspian Sea remain poorly understood. Here, we integrate satellite observations, in situ hydrological records and reanalysis data to examine recent drivers of the Caspian water loss. We show that total river inflow to the Caspian Sea has declined significantly, primarily due to reduced discharge from the Volga River. At the same time, precipitation over the basin has remained broadly stable, while …

Steel Corrosion In Underground Transportation Infrastructure, Amr M. Morsy, Islam A. Ebo, Shiv K. Janardhanan

Mineta Transportation Institute

Corrosion of buried steel, a critical component of American transportation infrastructure, remains one of the most insidious challenges due to the uncertainty associated with its estimates. Predicting when and how this corrosion happens is very difficult. This uncertainty grows exponentially with time, making corrosion estimation in the long term even more challenging, especially with buried steel and steel structures, which cannot even be monitored visually. While significant advancement has been made to understand the effect of the various corrosion parameters on soil corrosivity, there is a lack of a comprehensive understanding of how these factors collectively contribute to corrosion as …

Ocean-driven basal melting of Antarctic ice shelves plays an important role in the mass loss of the Antarctic Ice Sheet. Ice shelf cavity-resolving ocean models are a valuable tool for understanding ice shelf-ocean interactions and for simulating projections of ice shelf and ocean states under future climate. Designed to assess the current state of ice shelf–ocean modelling, the second Ice Shelf–Ocean Model Intercomparison Project, ISOMIP+, consists of 12 ocean model configurations submitted with a common, idealised experimental setup. Here, we focus on the experiments Ocean0–2, which are ocean models with idealised, static ice shelf geometries, but where the ocean reaches …

Spatiotemporal Dynamics Of Daily And Per Capita Vmt In California: A County-Level Analysis (2019–2023), Yong Lao, Bo Yang

Mineta Transportation Institute

Vehicle miles traveled (VMT) is a fundamental metric for assessing mobility trends and infrastructure needs. This study examines the spatial-temporal dynamics of daily VMT (DVMT) and per capita DVMT across California counties from 2019 to 2023, covering the pre-, mid-, and post-pandemic periods via GIS mapping and k-means clustering. To identify determinants of per capita DVMT, we compared traditional linear regression approaches (OLS, Ridge, LASSO, Elastic Net) with ensemble tree-based models. Specific results include: the ensemble models estimated using 2019–2022 data delivered substantially higher accuracy, achieving R² values exceeding 0.98; meanwhile, out-of-sample performance on 2023 data remained robust (R² ≈ …

Is Nostalgia The Hidden Mechanic Of Mmorpgs?, Zoee Sowders

Flash droughts are characterized by rapid onset and intensification, with severe impacts on agriculture and ecosystems. They often begin as meteorological droughts and, if conditions worsen, evolve into agricultural droughts. While precipitation deficit is often the primary driver, atmospheric and hydrological anomalies can exacerbate flash drought development. This study characterizes flash droughts across the Contiguous United States using remote sensing data from 2003 to 2020. A combination of satellite-derived meteorological, agricultural, and ecological variables are used to investigate large-scale flash drought development. Events are defined using root-zone soil moisture. We used the Aridity Index to assess how background aridity influences …

Faculty Research, Scholarly, and Creative Activity

It is increasingly acknowledged that high income countries do not enjoy universal drinking water coverage, with pockets of water insecurity persisting close to areas that have had high-quality, centralized water provision for half a century or more. The reasons behind this are complex, and effective ways to improve water security in these areas defy simple prescriptions. Nuanced measures that disaggregate the different facets of water insecurity are especially important as we attempt to understand and, crucially, improve water security in high-income countries.In this paper, we describe a qualitative protocol for assessing water insecurity at the household level in a study …
