"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 …

High Biochar Rate Improves Water Retention In Some Environmentally Sensitive Soils, Samundra Sigdel

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Improving water retention and other hydraulic properties is key to managing soil water and sustaining crop production under fluctuating and extreme weather events. We assessed how wood biochar (836 g C kg^-1) applied at 0, 6.25, 12.5, 25, and 50 Mg ha^-1 affected: i) soil hydraulic properties after 5 years and ii) corn and soybean yield, and biomass production of cereal rye cover crop (CC) and CC mix (cereal rye, radish, and winter pea) in sandy, sloping, and semi-arid soils in the central U.S. Great Plains over 6 years. Biochar affected field saturated hydraulic conductivity (K_{sat …}

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.

Data Centers Face Volatile Regulatory Landscape, Michael B. Gerrard

Sabin Center for Climate Change Law

The construction of new data centers for artificial intelligence has become a major engine of the U.S. economy. More than 700 data centers are now under construction across 40 states, with many more to come.

These are typically multi-billion-dollar projects. This boom is facing growing public opposition, which has led to an extremely volatile regulatory land-scape, especially at the state and local levels. That landscape is the subject of this article. This volatility has raised the cost of capital for data centers and led to the cancellation of many, and to heightened due diligence by lenders and others.

Divergent Belowground Strategies Of Savanna Grasses Under Varying Fire Regimes, Abigail C. Schmidt

All Graduate Theses and Dissertations, Fall 2023 to Present

Savannas are unique ecosystems, where trees and grasses live together across the landscape, not quite forming full forests or open grasslands. The ability for trees and grass to coexist is largely the result of widespread disturbances, such as fire. Fire in savannas is largely thought of in how it maintains plants above ground, however, fire also plays a key role in ecosystem and plant processes belowground. First, fire can change how soil nutrients, namely phosphorus, are cycled. Phosphorus is a key nutrient that plants need to function, and plants acquire phosphorus through their roots. Frequent fire can enhance phosphorus availability, …

Toward Risk-Informed Design Of Supercooling Heat Exchangers: Statistical Inference And Experimental Investigation Of Heterogeneous Ice Nucleation, Daniel B. Gardner

All Graduate Theses and Dissertations, Fall 2023 to Present

Ice-based cooling storage systems can reduce electricity costs and grid strain by making ice during off-peak hours and using it for air conditioning during the day. One promising design works by chilling water below its freezing point as it flows through a heat exchanger, then allowing it to freeze in a separate storage tank. The challenge is that the chilled water can freeze prematurely inside the heat exchanger itself, blocking the flow and shutting the system down. Preventing this unwanted freezing requires understanding how and where ice begins to form on surfaces, a process called nucleation.

This dissertation investigates ice …

Evolving Roles: School Counselors Addressing Mental Health In Pk-12 Education, Evin Daines

All Graduate Theses and Dissertations, Fall 2023 to Present

A significant number of children and youth are currently experiencing poor mental health. School counselors work with all students and are in a position to provide support to students experiencing mental health challenges. School counselors can also identify what may hinder children and youth from accessing mental health resources in their communities. This study explores how many school counselors engage in mental health counseling, how school counselors view their roles in addressing student mental health, and what barriers they perceive as keeping children and youth from accessing mental health and behavior services.

The Impact Of Ai On The Landscape Design Process, Jacob Owen Huff

All Graduate Theses and Dissertations, Fall 2023 to Present

Artificial intelligence (AI) is becoming more common in design fields, including landscape architecture. For example, AI has been used to visually analyze park aesthetics and generate landscape design concepts (Jahani et al., 2022; Senem et al., 2023; Ploennigs & Berger, 2023). This study explores how AI, specifically an image-generation tool called Midjourney, affects the design process for landscape architecture students.

Students completed two design projects—one using AI-generated images and one using traditional, non-AI precedent images. Their final designs were evaluated by professional landscape architects who did not know which designs had been influenced by AI. Students also completed surveys about …

Improving Teacher Adherence To Greeting And Attendance Routines Through Performance And Graphed Feedback, Caitlin Huppi

All Graduate Theses and Dissertations, Fall 2023 to Present

Schools establish expectations for teachers to create safe, organized, and welcoming environments, but teachers may not consistently follow these expectations throughout the school year. This study examined whether brief feedback could help four high school teachers more consistently greet students and scan IDs for attendance during passing periods. Teachers received graphs showing their performance and brief weekly feedback. All four teachers increased greeting behavior, and three increased attendance scanning. Teachers also rated the intervention as acceptable, feasible, and helpful. These findings suggest that brief feedback may be a practical way for school leaders to support consistent teacher implementation of school-wide …

A Laboratory Investigation Of Energy Dissipators At Embankment Dams, Nathan L. Young

All Graduate Theses and Dissertations, Fall 2023 to Present

Dams play a critical role in protecting communities from flooding and providing reliable water supplies. When large amounts of water pass through a dam’s spillway during floods, the discharge can travel at high speeds and carry potentially destructive kinetic energy that can damage the dam or erode downstream channels if that energy is not properly controlled. To reduce this risk, engineers commonly use hydraulic structures called energy dissipators that slow spillway discharge and safely release it downstream.

Commonly used energy dissipators at embankment dams include stilling basins that rely on a hydraulic jump – a sudden rise in water depth …

The Role Of Individual Specialization In Migration Phenology And How Restored Habits Are Used By Native And Nonnative Fishes, Austin Garner

All Graduate Theses and Dissertations, Fall 2023 to Present

Native fish species around the world have declined due to habitat loss, habitat fragmentation, and the spread of non-native species. Because these problems often happen at the same time and interact, recovery efforts can stall unless they address all of the factors limiting a species' comeback. The June sucker (Chasmistes liorus), native only to Utah Lake, UT, has declined for many of these reasons, though its recovery effort has made significant progress due in large part to a successful hatchery program. Yet, the recovery efforts have not yet been able to establish a self-sustaining population in Utah Lake, …

Magnetic Properties And Ultrafast Spin Dynamics In Quantum Materials, Trung Kien Mac

All Graduate Theses and Dissertations, Fall 2023 to Present

Modern electronics mostly work by moving electric charge, which generates heat and hence wastes energy, especially as devices become smaller and faster. An alternative is to use the spin of electrons (a tiny magnetic property) and related “valley” states in certain atomically thin materials to store and process information more efficiently. This thesis explores how magnetism and spin behavior can be created and measured in a family of ultra-thin materials known as van der Waals quantum materials. Three kinds of materials are studied. First, atomically thin semiconductors are shaped into narrow nanoribbons. Because of their narrow size, their edges can …

Juvenile Lifers: Adapting To Life While Doing Life, Tristin Faust

Theses, Dissertations and Culminating Projects

This qualitative study examined psychosocial maturation among individuals sentenced to life imprisonment for offenses committed during adolescence. Archival interview and survey data were analyzed for 30 men who had been resentenced and released after serving an average of 31 years in prison. Findings revealed a developmental progression across four stages: pre-incarceration, initial incarceration, catalysts for change, and later incarceration. Participants described entering prison with developmental immaturity compounded by trauma, unstable home environments, educational disruption, and antisocial peer influence. Their early years of incarceration were marked by anger, fear, misconduct, and survival-oriented behavior. Over time, participants identified discrete events and ongoing …

Examining Social Anxiety And Barriers To Engagement In School-Based Mental Health Services Among Black American Adolescents, Taylor Walls

Theses, Dissertations and Culminating Projects

Social anxiety is common among Black American adolescents, though research examining the experience of social anxiety among this population is very limited. Furthermore, few studies have explored how sociocultural factors, such as racial discrimination and mental health stigma, may shape Black American adolescents’ perceptions of social anxiety and school-based mental health services. Using qualitative methods, the present study explored Black American adolescents’ perceptions of social anxiety, barriers to help-seeking, and views regarding school-based mental health services. A total of 15 Black American high school students in the northeastern United States (ages 14-15 years; M=16.0, SD=1.2) participated in focus groups and …

Cognitive Flexibility In Broader Autism Phenotype: Does Bilingualism Benefit And Emotion Hinder?, Nardin M. Yacoub

Theses, Dissertations and Culminating Projects

The broader autism phenotype (BAP) is a milder manifestation of autistic traits just below the clinical threshold for Autism Spectrum Disorder (ASD), and provides a framework for studying and defining these traits in individuals related to autistic people. Cognitive flexibility (CF) is an executive functioning (EF) skill characterized by the ability to switch between tasks or thoughts based on environmental demands. The current study examined whether BAP was associated with CF and how bilingualism and emotion influenced this relationship across development. Previous research has found that bilinguals show enhanced task-switching abilities. Individuals with BAP may show differences in emotional processing, …

Predictors Of The Mother-Infant Bond: The Role Of Maternal Attachment Style, Parity, Race, And Motherhood Expectations, Samia Qadri

Theses, Dissertations and Culminating Projects

This study examined how maternal attachment style, parity, race, and motherhood expectations, individually and in interaction, predicted the quality of the mother-infant bond during the postpartum period. Grounded in a maternal feminist framework, the study used a quantitative, cross-sectional correlational design. Postpartum mothers aged 20–39 (N = 87) completed validated measures of maternal attachment style, motherhood expectations, mother-infant bonding, and depressive symptoms. Multiple regression compared a Primary Model containing the four focal predictors and planned interaction terms with a Secondary Model that added maternal depressive symptoms as a covariate. Depressive symptoms emerged as the strongest single predictor of bonding, and …

Economics Department Faculty Publications

Using temperature and employment data covering 16 regions from Q3 2003 to Q1 2022, this study examined the average and seasonal effects of temperature on year-on-year employment growth in the Philippines. Average effects are insignificant while seasonal effects are heterogeneous. During the dry and cool season (Q1), higher temperatures are associated with a temporary 0.0397% increase in employment growth. In contrast, higher temperatures in the dry and hot season (Q2) are associated with a persistent decrease of 0.1361% while higher temperatures during the wet and hot season (Q3) are associated with a persistent increase of 0.1450%, which is primarily driven …

Differential Effects Of Generative Artificial Intelligence On Formative And Summative Assessment Performance: A Quasi-Experimental Longitudinal Study, Md Istiak Morsalin

Master's Theses

Generative artificial intelligence has unsettled a core assumption of course assessment: that scores on unsupervised work reflect what students can do unassisted. This study tests whether the widespread availability of ChatGPT altered student performance differently on formative versus summative assessments in Business Analytics and Foundations, a required undergraduate quantitative-methods course taught by one instructor across nine cohorts. In a quasi-experimental longitudinal design, the Fall~2022 cohort ($n = 90$), the last to finish before ChatGPT's public release, serves as a control against eight post-ChatGPT cohorts spanning Spring~2023 through Summer~2025 ($N = 646$). Outcomes were drawn from McGraw-Hill Connect records using matched …

Examining Transcultural Approaches In Art Education: Transversality, Identity Formation, And Intercultural Understanding, Alexandra Grace Parsons

Master's Theses

Art education is often treated as marginal within formal schooling, valued as enrichment rather than recognized as a vital contributor to students' intellectual, cultural, and emotional development. Funding and policy decisions made by state and local bodies produce significant regional disparities in access to art education across the United States. This thesis examines how transcultural approaches to art education can respond to increasingly diverse, post-migrant school communities. Using a comparative qualitative case study design, the study analyzes program structures, partnership models, and pedagogical practices at Birmingham Arts School in the United Kingdom alongside schools within Fulton County and Atlanta Public …

Educator Experiences Of Schoolwide Pbis Discipline Implementation: Exploring School Culture In Private Pk–12 Schools, Jessica L. Guarneri

Electronic Theses and Dissertations

The purpose of this phenomenological study was to explore educators’ lived experiences implementing schoolwide Positive Behavioral Interventions and Supports (PBIS) discipline systems and to understand how those experiences influenced school culture in private PK–12 schools. Historically, PBIS focused on specific outcomes, such as reductions in discipline referrals, suspensions, and behavioral incidents. Though these indicators are critical, they do not consider in what way educators experience disciplinary systems, nor how their lived experiences affect routine interactions with students. Educators play a key role in implementing PBIS; their experiences foster consistency, trust, and sustainability. The participants included certified educators and administrators employed …

Staying The Course: Community College Student Lived Experiences On Program Completion And Motivation, Jessica Leigh Mills

Electronic Theses and Dissertations

The purpose of this phenomenological study was to explore the lived experiences of former community college students who successfully completed an associate degree, certificate, or program of study and to understand how they experienced the personal, institutional, and environmental factors that supported their persistence to completion. The study, guided primarily by Tinto’s (1975,1988) Model of Student Departure and was complemented by Bandura’s (1988) Social Learning Theory (SLT), and Maslow’s (1943) Hierarchy of Needs, explored the extrinsic and intrinsic motivations students attributed to their successful completion of their associate degree, certificate, or program of study. Twelve former community college students who …

A Geometric Morphometric Analysis Of Acetabular Shape Variation Across Bat Families, Jordan L. Huff

Electronic Theses and Dissertations

Bats are the only mammals capable of powered flight, and research is concentrated on this adaptation. Their non-flight locomotion has received comparatively little attention. Previous studies show that non-flight locomotor behaviors vary across families. Members of Pteropodidae are efficient climbers but cannot effectively walk, whereas Phyllostomidae and Vespertilionidae are better at terrestrial locomotion but show reduced arboreal capabilities. The non-flight locomotion of Hipposideridae and Rhinolophidae is less understood, although rhinolophids exhibit limited terrestrial locomotion. This study examined whether differences in locomotor behavior are associated with variation in acetabular morphology. A geometric morphometric analysis of acetabular shape was conducted across multiple …

Global Kinetic Dynamics Of Black Hole Magnetospheres And Accretion, Martin Luepker

Arts & Sciences Graduate Student Theses and Dissertations

The Event Horizon Telescope (EHT) has provided stunning images of the immediate vicinity of two supermassive black holes, M87* and Sgr A*, revealing the plasma swirling around them. To understand the complex emission observed, researchers have turned to general relativistic magnetohydrodynamic (GRMHD) simulations, which model the plasma as a fluid. These simulations have been successful in reproducing some features of the EHT images, but they rely on assumptions that do not apply in the low-density, high-magnetic-field environments around these black holes. General relativistic particle-in-cell (GRPIC) simulations offer a first-principles approach to modeling this environment, but their application to global black …

An Analysis Of Mating Strategies In Rotifers Inhabiting Temporary Habitats, Ariel Bollinger

Open Access Theses & Dissertations

Reproduction is critical for organisms inhabiting ephemeral aquatic habitats where desiccation risk favors rapid and successful mating. Monogonont rotifers rely on sexual reproduction to produce diapausing eggs that withstand harsh conditions. I investigated how mating behaviors vary among populations of five rotifer species based on the hydroperiod of their habitat: Epiphanes brachionus and E. chihuahuaensis were sampled from habitats with short (SH) and long (LH) hydroperiods; Euchlanis dilatata was collected from a short (SH) and a permanent habitat; and Plationus patulus and Sinantherina socialis were collected from a long (LH) and a permanent (Perm) habitat. I hypothesized that SH populations …

Power Signature-Based Hardware Security Techniques For The Internet Of Things, Ashish Mahanta

Dissertations

The rapid proliferation of the Internet of Things (IoT) has introduced significant security challenges, particularly concerning stealthy, instruction-level malicious code injections that evade traditional software defenses. While conventional power analysis techniques are highly effective at detecting such subtle abnormalities, they require capturing high-resolution, voluminous power trace data. This dependency necessitates bulky data acquisition (DAQ) instrumentation, power-hungry analog-to-digital converters (ADCs), and intensive computational resources, making these methods impractical for deployment on resource-constrained IoT devices. To bridge this critical gap, this dissertation presents a novel hardware security paradigm, the Power Rising and Descending Signature (PRIDES) methodology. Instead of quantizing actual power consumption …
