Nature-based learning has demonstrated positive outcomes for young children’s academic, social-emotional, and developmental growth; however, its implementation within school systems remains limited due to a lack of governance or organized oversight. This qualitative study examined how nature-based learning can be implemented with practical fidelity in Texas public schools while remaining aligned with state standards and school district policies. Grounded in Biophilia Theory, Attention Restoration Theory, and Experience Theory, the study explored educators’ perceptions as co-researchers into the practices and decision-making processes as they integrated nature-based learning into daily instruction.

Participants included experienced Texas public school educators teaching prekindergarten and kindergarten. …


Automated Testing And Enhancement For Autonomous Driving Systems, Mingfei Cheng Aug 2026

Automated Testing And Enhancement For Autonomous Driving Systems, Mingfei Cheng

Dissertations and Theses Collection (Open Access)

Autonomous Vehicles (AVs) rely on Autonomous Driving Systems (ADSs) to perceive their surroundings, predict the behavior of traffic participants, plan driving actions, and control vehicle motion in complex traffic environments. As AVs move toward large-scale real-world deployment, ADSs are expected not only to avoid collisions and traffic-rule violations, but also to make robust decisions, cooperate effectively with other AVs, and maintain high-quality driving behavior. However, the open, dynamic, and uncertain nature of driving environments makes the systematic testing and enhancement of ADSs a challenging problem.

Although scenario-based testing has made substantial progress in discovering safety-critical violations, several important limitations remain. …


Molecular Refinement Of The Taxonomy Of Pyrgulopsis Springsnails In Western North America, Michael K. Young, Kristine L. Pilgrim, Eric S. Miskow, Chante L. Lundskog, Kathryn E. Perez, Michael K. Schwartz Aug 2026

Molecular Refinement Of The Taxonomy Of Pyrgulopsis Springsnails In Western North America, Michael K. Young, Kristine L. Pilgrim, Eric S. Miskow, Chante L. Lundskog, Kathryn E. Perez, Michael K. Schwartz

School of Integrative Biological & Chemical Sciences Faculty Publications

Springsnails in the genus Pyrgulopsis in western North America have long been a dilemma for taxonomists. Defining species boundaries has been complicated by the presence of undiscovered or cryptic taxa, range over- or underestimation, species complexes representing an unknown number of species, and named species synonymous with other taxa. To address these issues, we conducted an array of molecular species delimitation analyses using sequences from up to 2 mitochondrial and 2 nuclear genes from over 5000 specimens representing 140 of the 151 currently recognized taxa. These analyses reaffirmed most species hypotheses, favored synonymy for some taxa and redrawing of species …

Paired-samples t-tests were conducted to determine statistically significant mean differences across the 10-year period. Findings revealed significant increases in EB enrollment, Hispanic enrollment, and economically disadvantaged enrollment, indicating that participating districts served increasingly diverse student populations with …


The Interplay Of Interdependence And Correlation In Bilateral Trade, Takashi Kunimoto, Cuiling Zhang Aug 2026

The Interplay Of Interdependence And Correlation In Bilateral Trade, Takashi Kunimoto, Cuiling Zhang

Research Collection School Of Economics

Following Crémer and McLean (1985, 1988) for finite type spaces and McAfee and Reny (1992) for continuous ones, we establish two respective sufficient conditions for the existence of efficient, ex ante budget-balanced mechanisms satisfying Bayesian incentive compatibility (BIC) and interim individual rationality (IIR) in bilateral trade settings with interdependent values and correlated beliefs. We then utilize the ex ante welfare (EAW) condition proposed by Kunimoto and Zhang (2026), which is necessary for the stricter requirement of ex post budget balance. We prove that while the EAW condition is sufficient in a two-type model and generalizes existing conditions in the literature, …

The Treatment Of Digital Assets In Insolvency, Nydia Remolina Leon, Aurelio Gurrea-Martinez, Daniel Liu

Research Collection Yong Pung How School Of Law

This article provides a comprehensive analysis of the treatment of digital assets in insolvency. Given that cryptoassets can be the subject of various transactions—including purchase, sale, custody, and lending—understanding their nature and implications in insolvency is relevant for any firm, not just cryptoexchanges. The article begins by offering a general overview of the world of cryptoassets. It then examines the nature of cryptoassets from accounting, financial, and legal perspectives. While much of the literature on insolvency and cryptoassets has primarily focused on the analysis of whether cryptocurrencies constitute property of the estate, this article explores additional issues, such as the …


Macroscopic Classical And Quantum Models Of Inverse Compton Scattering, Emerson Penn Rogers Aug 2026

Macroscopic Classical And Quantum Models Of Inverse Compton Scattering, Emerson Penn Rogers

Physics Theses & Dissertations

Inverse Compton sources — in which a relativistic electron beam scatters a laser pulse to produce tunable, collimated, high-energy radiation—have emerged as among the most promising compact radiation sources, with applications ranging from nuclear photonics to medical and nanoscale imaging and metrology. The most viable current tabletop configuration couples laser-wakefield acceleration with inverse Compton scattering, producing GeV-scale electron beams over millimeter distances. As laser intensities increase and electron energies grow, the interaction enters the radiation reaction regime, where the energy radiated by the electron becomes a significant fraction of its kinetic energy. Predicting the scattered electron energy spectrum — the …


Singapore In Global Value Chains: Implications Of The Trump Ii Tariffs, Pao-Li Chang, Ruoqing Chen Aug 2026

Singapore In Global Value Chains: Implications Of The Trump Ii Tariffs, Pao-Li Chang, Ruoqing Chen

Research Collection School Of Economics

This paper examines Singapore’s structural position in global value chains (GVCs) and the implications of the second Trump administration’s tariff escalation for Singapore and the broader ASEAN region. We proceed in three parts. First, using the ADB Multi-Regional Input–Output (MRIO) tables for 2019 and 2024, we characterise Singapore’s GVC participation and position. Singapore is the most GVCintensive economy in ASEAN, with nearly half of its gross exports comprising foreign value-added and a markedly downstream orientation. China is its dominant upstream partner across manufacturing and services—intermediating over 27% of foreign content in electronics and over 10% in chemicals—while Malaysia, Taiwan, and …


Laponite Nanosilicate As A Platform For Antigen–Adjuvant Co-Delivery In Vaccination, Haoyu Qi Aug 2026

Laponite Nanosilicate As A Platform For Antigen–Adjuvant Co-Delivery In Vaccination, Haoyu Qi

McKelvey School of Engineering Graduate Student Theses & Dissertations

Nanosilicates are two-dimensional, charged nanomaterials with tunable surface chemistry that enable electrostatic interactions with proteins and nucleic acids. These properties make Laponite nanosilicate a promising platform for vaccine delivery, where coordinated antigen–adjuvant presentation and lymph node delivery are important for shaping immune responses. This thesis investigated nanosilicates as scaffolds for lysozyme-based antigen delivery and co-delivery with CpG.

The preparation method reduced the apparent size of the NS–Lys–CpG complex at pH 10, although neutralization to pH 7 promoted larger aggregate formation. In vivo IVIS imaging after footpad injection showed persistent Cy7-associated fluorescence at the injection site for up to three weeks …


Capital Cities: The Intersection Of Power And Protest Urban Planning And Civic Design In Brasília And Washington, D.C., Noah Benjamin Gill Aug 2026

Capital Cities: The Intersection Of Power And Protest Urban Planning And Civic Design In Brasília And Washington, D.C., Noah Benjamin Gill

Theses

The physical environments of capital cities play a critical role in shaping how citizens interact with governmental power, particularly during moments of political unrest, protest, and democratic conflict. As both symbolic representations of national identity and functional centers of government, these urban landscapes influence how citizens approach, occupy, and confront civic institutions through their planning, architectural form, circulation networks, and spatial organization. Government buildings, public plazas, monumental landscapes, and civic axes do more than provide settings for political activity; they actively shape patterns of movement, visibility, accessibility, and control. The design of these spaces influences not only how democratic institutions …

Using a qualitative design, data were collected from seven Kindergarten educators through questionnaires, semi-structured interviews, and assessment samples. Data were analyzed using descriptive summaries and thematic analysis to identify patterns across participants' responses. The findings revealed that educators rely on a combination of standardized assessments, teacher-created tools, and ongoing classroom observation to evaluate foundational literacy skills, particularly phonological …


Intragroup Marginalization, Multiracial Identity Development, And Subjective Well-Being: A Qualitative Analysis, Anna Kim Nguyen Aug 2026

Intragroup Marginalization, Multiracial Identity Development, And Subjective Well-Being: A Qualitative Analysis, Anna Kim Nguyen

Theses and Dissertations

To date, there is little research on the relationship between multiracial identity, marginalization, and well-being, particularly research investigating whether identity can have a positive impact on well-being. The current study used live, semi-structured interviews and Interpretive Phenomenological Analysis (IPA) to aggregate the narratives of nine multiracial participants to explore their lived experiences of intragroup marginalization, multiracial identity development and integration, and well-being. Within the frames of the Intersectional Model of Multiracial Identity and Social Identity Model, five superordinate themes emerged across participants: (1) early racial meaning-making and internalized tension; (2) developing and negotiating a multiracial identity; (3) seeking and constructing …


Molecular And Cellular Mechanisms Of Neuromodulators In The Regulation Of Neural Activities And Memories In The Hippocampal Formation, Chidiebele Sharon Oraegbuna Aug 2026

Molecular And Cellular Mechanisms Of Neuromodulators In The Regulation Of Neural Activities And Memories In The Hippocampal Formation, Chidiebele Sharon Oraegbuna

Theses and Dissertations

The dentate gyrus (DG) and medial entorhinal cortex (MEC) are critical regions of the limbic system involved in spatial navigation, pattern separation, neurogenesis, learning and memory, and mood regulation. Alterations within the DG circuitry have been implicated in cognitive impairments in Alzheimer’s disease (AD), schizophrenia, major depressive disorder, and temporal lobe epilepsy. Disruption in the MEC is associated with the onset of AD pathology, temporal lobe epilepsy and schizophrenia. The roles of the DG and MEC in health and disease are mediated by their precise cellular activity. The main neurons of the DG are the glutamatergic granule cells (GCs) and …


Attachment Security And Sexual Compliance: Implications For Mental Health And Relationship Outcomes, Kimberly Tom Aug 2026

Attachment Security And Sexual Compliance: Implications For Mental Health And Relationship Outcomes, Kimberly Tom

Theses and Dissertations

Sexual compliance is defined as consenting to sexual acts despite not wanting to have sex. Even though sexual compliance behavior has been associated with a multitude of adverse outcomes, it remains an understudied sexual behavior. Previous research has suggested people with insecure attachment (i.e., avoidant, anxious, and disorganized attachment styles) may be more likely to engage in sexual compliance than their securely attached counterparts. Results from the current study found attachment anxiety, but not attachment avoidance, significantly predicted sexual compliance behavior. Gender and generalized anxiety symptoms also emerged as significant predictors of sexual compliance behavior. This study also sought to …


When Does Emigration Reduce Domestic Economic Activities? Evidence On The Loss Of Management Capacity From A Visa Lottery, Marup Hossain, Ahmed Mushfiq Mobarak Aug 2026

When Does Emigration Reduce Domestic Economic Activities? Evidence On The Loss Of Management Capacity From A Visa Lottery, Marup Hossain, Ahmed Mushfiq Mobarak

Cowles Foundation Discussion Papers

Economic development is often conceived as structural transformation and migration out of rural agriculture (Lewis, 1954; Fei & Ranis, 1964). Understanding development therefore requires us to identify how rural economies transform in response to emigration. We study how international migration reshapes domestic economic activity in origin households using a randomized visa lottery that gave Bangladeshi men job opportunities in Malaysia. Winning the lottery raises total household income through remittances, but income earned in Bangladesh declines due to contractions in nonfarm business activity. In contrast, crop income remains stable despite large reductions in agricultural input expenditures, because farming gets delegated through …


The Impact Of Liberalism On State Hard Power, Allen Wayne Hammerquist Aug 2026

The Impact Of Liberalism On State Hard Power, Allen Wayne Hammerquist

Graduate Program in International Studies Theses & Dissertations

This study examines the impact of liberalism on innovation, corruption, and, subsequently, state hard power in the international order. It hypothesizes that political, economic, and information freedoms facilitate the evolution of ideas and reduce corruption in society, resulting in a more efficient economy and greater wealth, income, and GDP per capita and, subsequently, greater state economic and military power. It employs four basic statistical models. The first two models examine the statistical relationship between domestic freedoms and innovation and corruption. They use a variety of metrics to measure the three key types of power that constitute the pillars of Western …


Structure Meets Context: A Simulation Study Of Centralized And Decentralized Decision-Making In Complex Environments, Murat Balci Aug 2026

Structure Meets Context: A Simulation Study Of Centralized And Decentralized Decision-Making In Complex Environments, Murat Balci

Engineering Management & Systems Engineering Theses & Dissertations

The question of when to centralize or decentralize decision-making authority is a foundational problem in organizational theory and management science. Yet existing research often favors decentralized structures, frequently treating them as universally superior, and provides limited guidance on when centralization may be more effective. Leaning toward decentralization without thoroughly exploring options leaves organizational designers without clear direction under varying environmental conditions. This study addresses that gap by developing and applying a simulation-based framework to evaluate the context-dependent effectiveness of centralized and decentralized decision-making structures.

Drawing on contingency theory and decision science, the study conceptualizes environmental complexity along two dimensions: dynamism …


Multi-Particle Reactions In Lattice Field Theories: From Euclidean To Quantum Computations, Marco Antonio Carrillo Bernal Aug 2026

Multi-Particle Reactions In Lattice Field Theories: From Euclidean To Quantum Computations, Marco Antonio Carrillo Bernal

Physics Theses & Dissertations

Amplitudes of multi-particle processes provide a probe of the dynamics described by relativistic quantum field theories. In the context of quantum chromodynamics, these amplitudes encode the way in which quarks and gluons are bound together by the strong nuclear force to form hadrons and govern their interactions. The non-perturbative nature of the strong interactions complicates the study of hadronic amplitudes from first principles. The most effective way of studying hadronic reactions non-perturbatively is the numerical framework known as lattice quantum chromodynamics. This method relies on theoretical formalisms that establish relations between numerical observables, such as finite-volume energy levels and matrix …

The focus in this qualitative study was to understand how MENA immigrant college students experience and make meaning of their academic journeys. Semi-structured interviews were used to explore the academic experiences of seven MENA immigrant college students in the United States and assess how acculturative stressors, personal strengths, coping strategies, and …


Computational And Ai Tools For Understanding Telomere-Associated Cancer Mechanisms, Eleni Adam Aug 2026

Computational And Ai Tools For Understanding Telomere-Associated Cancer Mechanisms, Eleni Adam

Computer Science Theses & Dissertations

Telomeres are the protective caps of the human chromosomes and are critical for genome stability. Dysfunctional telomeres caused by their erosion with age and cell proliferation as well as by defects in their maintenance is a major early event leading to genome changes and cancer. Subtelomeres possess the critical role of regulating adjacent telomeres. Due to their complex repeat structure and high variance from one person to another, these areas have not been analyzed in detail. We present a set of computational and machine learning tools to aid in the understanding of subtelomere structure and its rearrangements in cancer.

Initially, …


Public Participation In Community Redevelopment Agencies: A Mixed Methods Approach To Understanding The Impacts Of Collaboration In Public-Private Partnerships, Shannon Mcbride-Lewis Aug 2026

Public Participation In Community Redevelopment Agencies: A Mixed Methods Approach To Understanding The Impacts Of Collaboration In Public-Private Partnerships, Shannon Mcbride-Lewis

School of Public Service Theses & Dissertations

Local governments create community redevelopment agencies (CRAs) to enhance economic and redevelopment opportunities within their communities through public-private partnerships funded with tax increment financing (TIF). The use of increment revenue, the complexity of public-private partnerships, and the controversies surrounding CRAs can lead to community concerns and opposition. Collaboratively engaging the public in the development, implementation, and performance of CRA public-private partnerships is one way to improve program and project outcomes by enhancing engagement, equity, and accountability. This study asks does the level of resources (dedicated professional staff, consequential incentives, and TIF contribution) and formal public-private partnership programs of CRAs influence …


Residual Stress Informed Reconstruction And Failure Analysis Of Manufacturing Induced Composite Meso-Structure, Mohammad Nazmus Saquib Aug 2026

Residual Stress Informed Reconstruction And Failure Analysis Of Manufacturing Induced Composite Meso-Structure, Mohammad Nazmus Saquib

Mechanical & Aerospace Engineering Theses & Dissertations

A physics informed, AI-augmented framework is developed to enable digital twins of molded composite materials by linking manufacturing induced residual stresses to a local meso-structure. By reconstructing and explicitly modeling these architectures, the framework reveals how processing driven meso-structural variability governs stiffness, damage evolution, and failure. The work focuses on two technologically important systems: prepreg platelet molded composites (PPMC), characterized by inherently stochastic platelet architectures, and 2/2 twill glass fiber/PA6 organosheets, whose periodic but locally variable weave geometry influences mechanical response. For PPMC, the Residual Stress Informed Microstructure Reconstruction (ResIMiR) framework is introduced, combining thermoelastic strain fields with deep learning …

"Building Something Great!": Fifth-Grade Teachers Nurturing Hope Through Professional Learning Communities – A Telling Case, Matthew H. Huffaker

All Graduate Theses and Dissertations, Fall 2023 to Present

Teachers and educational leaders face numerous obstacles that can seem insurmountable but overcome through collaboration. “High-hope thinking provides a special advantage when we face obstacles in our goal attainment” (Snyder, 1994). Effective PLCs provide the fertile ground for teacher collaboration, influencing schoolwide communities and student learning (DuFour et al., 2016; Hord, 2004; van Es, 2012). Collaboratively identifying challenges and coming up with solutions with the support of others (what effective PLCs do) is an ideal setting for observing hope.

This study explored how hope is fostered among teachers during their weekly professional learning community meetings. Further, this study examined how …

Utility Of The Recombinase Driver Cx3cr1-Ert2 Rat Strain In Nicotine Self-Administration, Ashley M. White, Ashley J. Craig, Daryl L. Richie, Christa L. Corley, Percell T. Kendrick, Kathleen R. Mcnealy, Michael D. Scofield, Cassandra D. Gipson

Psychology Faculty Publications

Smoking remains a leading preventable cause of death, and nicotine is the primary substance responsible for maintaining use of tobacco products. Preclinical rodent models have shown that neuroimmune signaling is dysregulated by nicotine self-administration (SA) within the nucleus accumbens core (NAcore). Microglia are the resident brain immune cell and prior studies have shown that they play an important role in nicotine-related behaviors. However, while transgenic mouse lines allow for specific evaluations of microglia to determine their role in neurobiology and behavior, there are fewer tools available for rats as a model species, thus limiting our ability to evaluate specific contributions …


The Church And Nature’S Cathedral: Catholics, Protestants, And The Yosemite Chapel, Adam Hogan Aug 2026

The Church And Nature’S Cathedral: Catholics, Protestants, And The Yosemite Chapel, Adam Hogan

Eastern Sierra History Journal

John Muir saw nature and national parks as religious symbols themselves. Since Muir’s day, generations of Americans have worshipped in the outdoor sanctuaries. However, while much scholarly attention has focused on national parks as symbols or religious icons, scholars have paid far less attention to the actual church services that have taken place in America’s national parks. Yet, a church in a national park presents many complications, and Adam Hogan explores these dilemmas through a history of the controversies surrounding who could pray in the Yosemite Chapel.


The Evolution Of Hymenopteran Recombination Rates, Timothy John Delory Aug 2026

The Evolution Of Hymenopteran Recombination Rates, Timothy John Delory

All Graduate Theses and Dissertations, Fall 2023 to Present

Individuals of some species mix their DNA frequently when producing sex cells, while others do so much less. Hymenopterans (ants bees and wasps) are especially useful for understanding this variation for several reasons. They show large differences in this frequency of shuffling, or rate of recombination, have well-studied genomes, and vary widely in how they live and reproduce. I capitalized on these features examines how recombination rates have evolved in this group at the trait, and gene level.

First, I revisited long-standing ideas about why recombination rates differ among these species, incorporating more than a decade of new research. This …


Casual Killing In The Home: Ecological Citizenship And The Micro-Geopolitics Of Mosquito Cohabitation, Orlando Woods, Junxi Qian Aug 2026

Casual Killing In The Home: Ecological Citizenship And The Micro-Geopolitics Of Mosquito Cohabitation, Orlando Woods, Junxi Qian

Research Collection College of Integrative Studies

This article explores how the visceral acts of being bitten by and killing mosquitoes can underpin the formation of ecological citizenship. This form of citizenship is premised on human-nature entanglement and raises questions concerning how the rights and responsibilities stemming from such entanglement become distributed across the public and private domains. As a space in which mosquito cohabitation is contested daily, the home is a key site through which ecological citizenship can be forged and theoretical debates concerning urban political ecology can be extended. Human-mosquito entanglements in the home can reveal the limits of public pest management strategies, the partiality …
