California Utility-Scale Solar Energy Land Use Impacts On Species And Ecosystems, Ingrid Salazar Aug 2025

California Utility-Scale Solar Energy Land Use Impacts On Species And Ecosystems, Ingrid Salazar

Master's Theses

Utility-scale solar energy (USSE), defined as projects of at least 1 megawatt, is rapidly expanding in California, which generated 37.5% of its electricity from renewables in 2023, with 24% coming from solar. While USSE supports decarbonization, it can also cause environmental harm, including biodiversity loss, habitat fragmentation, and land conversion. This study uses ArcGIS Pro 3.4.0 and public environmental data to analyze the spatial distribution of USSE projects, land use changes from 2013 to 2023, and occurrences of at-risk species across California’s bioregions. USSE development is heavily concentrated in the Mojave Desert, San Joaquin Valley, and Colorado Desert, which are …

To gain molecular and mechanistic insights into initiation of the RAS-RAF signaling cascade, we developed and used a combination of multiscale simulation and experimental approaches. The influence and impact of the membrane on RAS and RAF proteins is a factor we are just beginning to understand and appreciate in more detail. Molecular simulation is an ideal methodology to further study this complicated relationship between the membrane and associated proteins. Our previous work using Multiscale Machine-learned Modeling Infrastructure investigated different lipid compositions solely around the KRAS4b protein and the interplay between protein behavior and these membrane environments. Multiscale Machine-learned Modeling Infrastructure …


Riparian Restoration Increases Soil Microbial Biomass In Marin County Rangelands, But Soil Carbon Stock Is Less Responsive, Sherilyn Kathryn Reinhart Aug 2025

Riparian Restoration Increases Soil Microbial Biomass In Marin County Rangelands, But Soil Carbon Stock Is Less Responsive, Sherilyn Kathryn Reinhart

Master's Theses

Land use change has caused the degradation of 70% of the Earth’s soils, directly altering soil microbial communities and carbon cycling. Interest in carbon farming practices is growing, but studies that document the nuances of soil carbon flux in specific bioregions are still too few. In this study, I examined how one practice, riparian restoration, alters soil carbon stock and microbial community structure over time. Using a paired sampling time series design, I collected soil samples from twelve riparian forests and adjacent rangelands near Marin County, California. Young and mature sites ranged from five to 29 years since restoration, and …

Background: Asian American, Native Hawaiian, and Pacific Islander (AANHPI) populations have diverse cultural, immigra-tion, and sociodemographic characteristics. Aggregated data could mask substantial differences in substance use between cultural subgroups in this population. Yet, studies examining substance use among the AANHPI population are limited. Objective: This study aimed to describe cigarette, cannabis, and alcohol use among AANHPI adults by cultural subgroup and sex. Methods: We analyzed data from 3411 AANHPI respondents of a multilingual national survey “COMPASS” during December 2021-May 2022. Primary outcomes were self-report current (every day or some days) use of cigarettes, cannabis, and alcohol. Cultural subgroups included Asian …

High Abundances Of Crustose Coralline Algae Inside Cryptic Coral Habitats Linked To Coral Reef Functioning, Anna Rothstein, Orion S. Mccarthy, Sophie Luu, Emily L.A. Kelly, Philip Heller, Stuart Sandin, Jennifer E. Smith, Maya S. Devries

Faculty Research, Scholarly, and Creative Activity

Cryptic habitats on coral reefs consist of crevices, tunnels, and holes that are estimated to comprise 30%–75% of the total reef surface area. These large habitats are vastly understudied because they are often difficult to access. Crustose coralline algae (CCA) are thought to perform important ecological functions, including calcium accretion, both inside cryptic habitats and on the exposed (top) reef. Using GoPro cameras, we surveyed 250 coral crevices from 13 reefs on West Maui, Hawai‘i. We compared relative CCA cover between crevice microhabitats and the well-studied top-reef and identified abiotic and biotic factors that correlated with CCA abundance. We found …


Correlations Of Intersectional Identity Cohesion And Growth In Queer And Transgender Black, Indigenous, And People Of Color, Zoha T. Qader Aug 2025

Correlations Of Intersectional Identity Cohesion And Growth In Queer And Transgender Black, Indigenous, And People Of Color, Zoha T. Qader

Master's Theses

Past research has found that identity cohesion (how integrated multiple identities are) is a protective factor that moderates the relationship between intersectional microaggressions and mental health outcomes. Individuals with higher identity conflict (multiple identities clashing) had anxiety and depression symptoms that could be predicted by the distress they experienced from intersectional microaggressions. For those with high identity cohesion, this was not the case. While compelling, the question remains, what are the factors that contribute to identity integration versus identity conflict? The present study will utilize existing data of 417 QTBIPOC individuals. Ratings of LGBTQ+ community belonging and engagement, and LGBTQ+ …


Modeling Lensed Quasars With Neural Posterior Estimation: Complex Mass Models, Logan C. O’Brien Aug 2025

Modeling Lensed Quasars With Neural Posterior Estimation: Complex Mass Models, Logan C. O’Brien

Master's Theses

The Vera C. Rubin Observatory is expected to discover ∼ 103 galaxy-scale strongly lensed AGN systems during its 10 year operation conducting the Legacy Survey of Space and Time (LSST). I use a machine learning neural posterior estimation method to automatically model these systems with the intention of using them for time-delay cosmography, to constrain the Hubble constant and, ultimately, the properties of Dark Energy. In the work shown here, the neural network that I utilize is trained on simulated lens systems with simple mass distributions that consist of a single main deflecting galaxy. I am testing the robustness of …


Learning Structure With Multivariate Information Bottleneck And Exploration Of New Methods In Sequential Decision Making, Volodymyr Makarenko Aug 2025

Learning Structure With Multivariate Information Bottleneck And Exploration Of New Methods In Sequential Decision Making, Volodymyr Makarenko

Master's Theses

Research in useful information extraction has been motivated by the increasing demand to extract insights from unstructured data, and by the need to store and transmit great volumes of information, often originating in unstructured data such as videos. Research in rate distortion and information bottleneck paved the path for understanding and guiding the design of lossy encoders, capable of extracting relevant information. Independently, research in deep representation learning has enabled numerous applications for unstructured high-dimensional data such as images. However, the interpretability of the deep learning methods remained limited. Several desired properties of learned representations have been suggested, including disentanglement. …


Seasonality In Terminus Ablation Rates For The Glaciers In Greenland (Kalaallit Nunaat), K. C. Aman, Ellyn M. Enderlin, Dominik Fahrner, Twila Moon, Dustin Carroll Aug 2025

Seasonality In Terminus Ablation Rates For The Glaciers In Greenland (Kalaallit Nunaat), K. C. Aman, Ellyn M. Enderlin, Dominik Fahrner, Twila Moon, Dustin Carroll

Faculty Research, Scholarly, and Creative Activity

Marine-terminating glaciers of Greenland (Kalaallit Nunaat) have been losing mass since the 1990s, with a substantial portion caused by the effects of dynamic change. Conventional assessments of dynamic mass loss, however, often ignore the influence of terminus advance or retreat on the timing of mass loss. Here, we construct and analyze a decade (2013-2023) of monthly ice flux driven both by temporal variability in ice flow (i.e., discharge) and terminus position change - collectively called terminus ablation - for 49 marine-terminating glaciers in Greenland. We calculate terminus ablation rates using open-source datasets, including terminus position, ice surface elevation, ice thickness, …

The Effectiveness Of Kolmogorov–Arnold Networks In The Healthcare Domain, Vishnu S. Pendyala, Nivedita Venkatachalam

Faculty Research, Scholarly, and Creative Activity

Kolmogorov–Arnold Networks (KANs) have recently emerged as a powerful alternative to traditional Artificial Neural Networks (ANNs), offering superior accuracy and interpretability, which are two critical requirements in healthcare applications. This study investigates the effectiveness of KANs across a range of clinical tasks by applying them to diverse medical datasets, including structured clinical data and time-series physiological signals. Compared with conventional ANNs, KANs demonstrate significantly improved performance, achieving higher predictive accuracy even with smaller network architectures. Beyond performance gains, KANs offer a unique advantage: the ability to extract symbolic expressions from learned functions, enabling transparent, human-interpretable models—a key factor in clinical …


Post-Fire Succession In An Old-Growth Coast Redwood (Sequoia Sempervirens) Forest In The Santa Cruz Mountain Bioregion, Mojgan Mahdizadeh Aug 2025

Post-Fire Succession In An Old-Growth Coast Redwood (Sequoia Sempervirens) Forest In The Santa Cruz Mountain Bioregion, Mojgan Mahdizadeh

Master's Theses

Fire is a common disturbance in the western United States, and variation in its frequency and intensity can significantly impact species recovery and distribution across ecosystems. While fire frequency and intensity are increasing in coast redwood forests, little is known about how this forest type responds to high-intensity wildfires. In 2020, a high-intensity wildfire burned large portions of the coast redwood forest in the Santa Cruz Mountains, including over 1,700 ha of old-growth. This event created a unique opportunity to evaluate post-fire succession. This research assessed vegetation recovery across high and low to moderate severity burned areas using random sampling …

The San Francisco Bay Area lacks publications on erosion rates and their relationship to restraining bend fault geometry. This thesis presents a detailed geochronologic study of erosion rates from the Mission Hills along the Calaveras, Mission, and Hayward faults located northeast of San Jose, California. The goals are to provide erosion rate values where none currently exist and to gain a better understanding of how fault geometry influences topography along restraining bends. To quantify the erosion rate of these faults, river sediments containing 10Be were collected from 14 catchments using well-established protocols. Of the successfully processed samples, the erosion rates …

A Place For Ancient Philosophy In Axial Age Historiography, John R. Shook Aug 2025

A Place For Ancient Philosophy In Axial Age Historiography, John R. Shook

Comparative Philosophy

Long-standing debates over historiographical approaches to the Axial Age have distracted the history of philosophy from its own disciplined inquiry into the breadth and depth of ancient thought beyond the Greeks. The philosopher Karl Jaspers offered a vista for seeing commonalities among ancient innovations and discerning continuities along history to modern times. That dual agenda divided Axial historiography with the question of whether axiality reflects creativities of ancient systems or have modern reflections created images of axiality. A singular chronology for humanity encourages a mode of philosophical history open to providential designs, epochal turns, spiritual evolutions, psychological leaps, or cognitive …


Moral And Ethical Nature In Confucian Liang-Zhi And Islamic Fitra: Comparative Perspectives On Innate Morality, Yanrong Shi Aug 2025

Moral And Ethical Nature In Confucian Liang-Zhi And Islamic Fitra: Comparative Perspectives On Innate Morality, Yanrong Shi

Comparative Philosophy

This article offers a comparative philosophical analysis of Confucian liang-zhi (innate moral knowledge) and Islamic fitra(primordial nature), focusing on their accounts of innate morality and moral epistemology. Drawing on classical Confucian sources—especially the praxis-oriented interpretation of Wang Yangming—and foundational Islamic texts and commentary, the study demonstrates that both traditions posit an inborn moral faculty grounding ethical universality and responsibility. Wang Yangming’s liang-zhi is conceived as an innate moral principle that, under the imperative of zhi (to actualize or extend), is continually activated through moral practice. In parallel, fitra is understood as a God-given orientation to truth, cultivated and safeguarded through …


The Conventional Emptiness Of Human Beings: Reviewing Archer’S Theory Of Agency Through Nagarjuna’S Looking Glass, Federico Podestà Aug 2025

The Conventional Emptiness Of Human Beings: Reviewing Archer’S Theory Of Agency Through Nagarjuna’S Looking Glass, Federico Podestà

Comparative Philosophy

Margaret Archer is probably the critical realist who has most significantly affected the debate around the relationship between social structure and agency. In the volume, Being Human: The Problem of Agency, she aims to better define what is meant by the properties and causal powers of agency itself, i.e., self-consciousness and reflexivity. In this paper, this theoretical attempt is reviewed through the critical standpoint of Nagarjuna. Nagarjuna’s philosophy appears to be a particularly compelling tool for criticizing Archer’s theory. Claiming the emptiness of everything, the founder of the Buddhist Madhyamaka school provides a critical perspective for revising the distinctiveness of …


A Constructive Engagement Between Oxford Ordinary Language Philosophy And Latin American & Latine Liberatory Philosophy, Alessandro R. Moscaritolo Palacio Aug 2025

A Constructive Engagement Between Oxford Ordinary Language Philosophy And Latin American & Latine Liberatory Philosophy, Alessandro R. Moscaritolo Palacio

Comparative Philosophy

In this paper, I bring into dialogue a movement in Latin American social and political philosophy – which I have named Latin American and Latine Liberatory Philosophy – and a Western, or more precisely global North, philosophical movement sometimes called Ordinary Language Philosophy. By ‘Latin American and Latine Liberatory Philosophy’, I refer to a movement, adumbrated at the dawn of the 19th century and developed during the 20th century, whose guiding theme is the political, social, and cultural liberation of Latin America (and global South peoples more generally). By ‘Ordinary Language Philosophy’, on the other hand, I refer …


Reassessing The Deontological Undercurrents In Mo Zi’S Ethical Thought, Nuno Miranda Aug 2025

Reassessing The Deontological Undercurrents In Mo Zi’S Ethical Thought, Nuno Miranda

Comparative Philosophy

This article reexamines Mo Zi’s ethical philosophy, challenging the dominant interpretation of Mohism as a purely consequentialist or proto-utilitarian system. While Mo Zi’s emphasis on social utility—such as material welfare, population growth, and aversion to warfare—aligns with outcome-oriented reasoning, I argue that his invocation of the will of Heaven introduces a deontological dimension. Heaven’s will serves not merely as a heuristic for maximizing benefits but as an absolute moral standard, demanding adherence to duties like universal love and non-aggression, irrespective of immediate practical gains. Through a close reading of the Mo-Zi corpus, this study reveals a hybrid ethical framework that …


How Theravāda Buddhism Enriches The Language Of Thought Hypothesis: Beyond Syntax, Juanjuan Cheng, Sumanasara Sandamadulle Aug 2025

How Theravāda Buddhism Enriches The Language Of Thought Hypothesis: Beyond Syntax, Juanjuan Cheng, Sumanasara Sandamadulle

Comparative Philosophy

The Language of Thought Hypothesis (LOTH) posits that mental states operate through a language-like representational system physically implemented in the brain. However, this purely symbolic approach faces a significant limitation: certain mental phenomena—such as intuitions, emotions, and intentions—lack the syntactically compositional structure required by LOTH and therefore cannot be adequately explained within its symbolic framework. To address this theoretical challenge, we turn to Theravāda Buddhism (TB), an early Buddhist tradition that integrates rigorous philosophical inquiry with meditative practice. Remarkably, TB began to prefigure a solution to LOTH’s limitations over 2,300 years ago. Although LOTH and TB differ …

The Impact Of Early Life Experiences On Math Confidence, Nhu X. Hin Aug 2025

The Impact Of Early Life Experiences On Math Confidence, Nhu X. Hin

Master's Theses

Students form beliefs about their academic abilities through a combination of emotional experiences and early learning environments. While prior research has documented how math anxiety can undermine performance and how early experiences with math-typed activities can foster positive attitudes, less is known about how these factors collectively influence students’ math confidence. The present study investigates how math anxiety, engagement in childhood math-typed activities, and perceived support for math-related learning contribute to college students’ confidence in their math abilities. Participants (N = 102) completed self-report measures assessing each of these constructs. A multiple regression analysis revealed that the three predictors collectively …

Vertiport Location Selection And Optimization For Urban Air Mobility In Complex Urban Scenes, Yannan Lu, Weili Zeng, Wenbin Wei, Weiwei Wu, Hao Jiang

Faculty Research, Scholarly, and Creative Activity

Vertiports, as dedicated facilities for electric vertical takeoff and landing (eVTOL) aircraft, are essential to ensure the efficiency and sustainability of Urban Air Mobility (UAM). However, UAM infrastructure site selection has become increasingly complex due to limited land availability, complex spatial conditions, and the need to balance multiple objectives. Focusing on passenger-carrying UAM operations, this study proposes a systematic framework for vertiport site selection. First, key factors are classified into high, medium, and low levels across the safety, economic, and social dimensions, forming a modular evaluation system. A GIS-based spatial screening process is developed to identify potential vertiport locations. Subsequently, …


The Anti-Work Attitude Scale: Conceptualizing And Measuring The Resistance To The Institution Of Work, Alayna Del Rosario Aug 2025

The Anti-Work Attitude Scale: Conceptualizing And Measuring The Resistance To The Institution Of Work, Alayna Del Rosario

Master's Theses

Recent shifts in labor discourse have drawn attention to rising burnout, declining organizational commitment, and diminishing job satisfaction, which challenge traditional assumptions about the centrality and desirability of work. These tensions have given rise to the concept of anti-work, a growing discourse that questions the moral, economic, and psychological foundations of work itself. Despite its cultural relevance, anti-work remains largely undertheorized and unmeasured in empirical research. Drawing from interdisciplinary scholarship, this study defined anti-work as a negative critique of work as a social construct, questioning its value, purpose, and impact on individuals and society. Anti-work was operationalized through two higher-order …


The Relationship Between Hindrance Demands And Work Engagement: The Moderating Role Of Resilience, Adoré Davis Aug 2025

The Relationship Between Hindrance Demands And Work Engagement: The Moderating Role Of Resilience, Adoré Davis

Master's Theses

The coronavirus pandemic decreased work engagement globally due to increased hindrance demands. Many organizations were motivated to increase work engagement, which is positively correlated with beneficial organizational outcomes. The intention of this study is to examine if personal resources like resilience moderate the relationship between hindrance demands and work engagement. Hindrance demands are refined from job demands and hindrance stressors, which are stressors that impede progress in employees. Resilience is a personal resource correlated with pro-social behavior, internal locus of control, and higher levels of empathy. Resilience as a personal resource has mainly been studied as a predictor of work …

Additive manufacturing (AM) is revolutionizing the production of custom components with complex internal geometries, essential for high-performance applications in diverse fields such as medicine and defense. These AM parts optimize strength while minimizing weight by utilizing internal lattice structures consisting of large quantities of small interconnected struts. However, the complexity of these structures, combined with the challenges of using X-ray Computed Tomography (XCT) data, makes validation of part reliability difficult. This ultimately inhibits the development of novel parts for our collaborating material scientists. We introduce LatticeAnalytics, a novel framework specifically designed for visual inspection of defects in these lattice structures. …

Acoustic Presence Of Humpback Whales (Megaptera Novaeangliae) In U.S. West Coast National Marine Sanctuaries, John C. Barkowski

Master's Theses

Humpback whales are one of many species of marine mammal that utilize sound in multiple aspects of their lives in the oceans. By collecting acoustic data from multiple areas across the habitat of these animals, we can investigate spatiotemporal patterns in their sound production to better understand their life history strategy. This study uses three years of passive acoustic data collected concurrently from three U.S. West Coast National Marine Sanctuaries to look for spatiotemporal patterns in humpback whale song and non-song vocalizations. Additionally, this study investigated correlations between upwelling conditions and the onset of song to explore links between the …


Working Memory In Major Depressive Disorder: A Meta-Analysis Of Structural And Functional Brain Differences, Eunji Back Aug 2025

Working Memory In Major Depressive Disorder: A Meta-Analysis Of Structural And Functional Brain Differences, Eunji Back

Master's Theses

Major depressive disorder (MDD) is one of the most prevalent mental health disorders in the US and is characterized by depressed mood and loss of interest. Many MDD patients also experience difficulties with executive function, including working memory. Neuroimaging studies reveal structural and functional brain differences between MDD patients and healthy controls that may underlie these working memory difficulties, but findings have been mixed. A quantitative synthesis of neuroimaging data through a meta-analytic approach offers a promising avenue to identify commonalities across studies. We conducted separate meta?analyses of structural and functional magnetic resonance imaging (MRI) data, with the latter focused …
