From Surfaces To Scaffolds: Tuning Hydrogel Microenvironments To Control Cell-Material Interaction, Tran Truong

Doctoral Dissertations

The last 40 years of in vitro cell and tissue biology have relied heavily on tissue culture plastic (TCPS), which offers high transparency and a simple, user-friendly method for growing adherent cells. Unfortunately, TCPS has limitations, such as its rigidity, which may alter cell shape, disrupt cell signaling, and ultimately affect cell fate. The poor control over the adsorption of proteins to TCPS and the fact that surface chemistry is fixed on this material are only two examples of the limitations that motivate the development of hydrogel-based culturing platforms, during which the mechanical properties, charge, hydrophobicity, and ligand presentation can …

Entrainment And Surfacing Dynamics Of Submerged, Buoyant Turbulent Jets, Zeeshan Saeed

Doctoral Dissertations

Turbulent entrainment (TE) in buoyant jets plays a key role in dispersing environmental contaminants, carrying significant socio-economic implications. For example, the transport of heat and solutes through submarine volcanoes and the discharge of subglacial meltwater crucially affect the marine ecosphere. This, in turn, impacts coastal communities, the supply chains they support, and the broader socio-economic landscape. Therefore, advancing our understanding of how submerged buoyant jets mix and developing remote sensing tools to help monitor their changing status is crucial for devising strategies to mitigate marine-related challenges quickly, economically, and effectively. Therefore, this dissertation has three primary objectives: (I) examine the …

Emotional Complexity In Context: Within-Person Variability In Emotional Granularity, Emotion Covariation, And Emodiversity, Kristen Diann Petagna

Doctoral Dissertations

Key features of emotional complexity include emotional granularity, the ability to identify feelings with precision; emodiversity, the number and evenness of different emotions experienced; and emotion covariation, the tendency to experience positive and negative emotions independently. Prior work has largely treated these features as trait-like. This dissertation examines whether these features are dynamic by investigating how they vary within individuals over time and across contexts. In Chapter 2, participants (N =123) reported their emotions multiple times a day for 6 weeks and completed biweekly assessments of mental health symptoms. Emotional granularity and covariation increased over time, whereas emodiversity decreased, and …

A Variance Decomposition Approach To Inconclusives In Forensic Black Box Studies, Amanda Luby, Joseph B. Kadane

Mathematics and Statistics Faculty Work

In the USA, ‘black box’ studies are increasingly being used to estimate the error rate of forensic disciplines. A sample of forensic examiner participants is asked to evaluate a set of items whose source is known to the researchers but not to the participants. Participants are asked to make a source determination (typically an identification, exclusion, or some kind of inconclusive). We study inconclusives in two black box studies, one on fingerprints and one on bullets. Rather than treating all inconclusive responses as functionally correct (as is the practice in reported error rates in the two studies we address), irrelevant …

Different Destinations: Clarifying And Addressing Pipeline Problems For Women In Academic Archaeology, Scott R. Hutson, Jaycee Castro, Bruno Athie Teruel

Anthropology Faculty Publications

In STEM fields, women tend to leak out of the pipeline to the professoriate. In archaeology, however, robust databases and chronological control reveal that there is no leakage from earning a PhD to tenure-track positions. Nor is there a leak from assistant professor to associate professor. Nevertheless, men get hired as faculty in PhD programs more often than women. This is important because PhD programs are research-intensive and train future leaders. Furthermore, women PhD students have women as advisers more than often men and report advantages to this arrangement. Yet with fewer women faculty in PhD programs, women mentors are …

A World Of Connection: Asd, Morgan M. Gayton

Entry Level Occupational Therapy Doctoral Capstone Projects Class of 2026

Autism Spectrum Disorder is a diagnosis that affects many school-aged children (CDC, 2025). Autistic children can have more difficulties engaging with both their peers and their families, which can lead to a lack of social participation. A World of Connection: ASD was a doctoral capstone project centering on social participation for autistic youth. The project blended the capstone student’s expanded knowledge in performing arts with their education in Occupational Therapy to create a 4-part capstone experience. A scoping review targeting the question “what are the most effective performing arts methods to enhance the social participation of autistic children” yielded 9 …

Autonomous Uav Mission Planning Under Threat Using Model Predictive Control With Proportional-Navigation Pursuers, Mehmet B. Ozcelik

Mechanical and Aerospace Engineering Theses

Autonomous unmanned aerial vehicles (UAVs) operating in contested environments must

complete mission objectives while avoiding restricted regions, radar exposure, and pos-

sible interception. This thesis develops a MATLAB-based simulation framework for

two-dimensional UAV mission planning under threat using model predictive control and

proportional-navigation chasers. The mission requires the UAV to travel from a start

location to a goal while visiting required checkpoints and avoiding no-fly zones and radar

regions. A chaser attempts to intercept the UAV using either a basic pure-pursuit-style

law or a proportional-navigation guidance law.

The framework integrates environment generation, augmented visibility-graph rout-

ing, waypoint management, UAV kinematic …

Llm-Driven Closed-Loop Uav Control With Obstacle-Aware Model Predictive Control, Halimcan Yasar

Mechanical and Aerospace Engineering Theses

This thesis presents a closed-loop control architecture for uncrewed aerial vehicles (UAVs) in which a large language model (LLM) serves as a high-level decision module operating over a persistent, metric 3D world model.

Rather than generating low-level commands or open-loop plans, the LLM selects one parameterized maneuver per decision step from a small, verified library of flight primitives conditioned on a structured representation of the drone state, tracked object positions, and mission specification.

Translational motion is executed by a planar model predictive controller (MPC) with soft obstacle avoidance, using obstacle hypotheses provided by the LLM, so that safety-critical constraint handling …

Little Minds, Big Emotions is a doctoral capstone project designed to support the development of emotional regulation skills in preschool-aged children through the areas of program development, education, and clinical skills development. Emotional regulation is an essential component of children' s participation, social interactions, and overall well-being, yet many young children experience difficulties identifying emotions and using effective calming strategies. The purpose of this capstone project was to develop and implement a developmentally appropriate, play-based emotional regulation curriculum for preschool children while also providing educational resources for caregivers. This program was implemented three days a week for 14 weeks at …

Coerced Corporate Consent, Jason J. Jarvis

Emory Law Journal

Corporations are not human beings, but they have rights, including the constitutional right of due process. The United States Supreme Court recently held in Mallory v. Norfolk Southern Railway Co. that due process is satisfied when a state requires that a corporation consent to personal jurisdiction before it can conduct business in that state. The Court did not analyze, however, whether such business registration statutes can be coercive and, if so, when. These unanswered questions expose corporations to previously unexplored risks.

Involuntary consent is an oxymoron. Consent must be knowing and voluntary, and consent extracted by threat is coerced and …

Unlikely Criminals: Inside The Ivf Drug Grey Market, Maybell Romero

Emory Law Journal

In this Article, I admit to committing crimes, specifically buying fertility drugs on the in vitro fertilization (IVF) drug grey market. Drawing from personal experience, I explore how people wanting to undergo IVF turn to the criminalized fertility drug grey market to access necessary but prohibitively expensive fertility medications that would otherwise be out of reach. In the absence of comprehensive insurance coverage, patients often rely on informal online communities to obtain medications at lower prices, often from other patients whose IVF cycles have been canceled or who have excess drugs. While these transactions fulfill a critical need, they also …

Making Environmental Cancer Risk Legally Visible: Legal Epidemiology, Chemical Regulation, And The Failures Of Cancer Cluster Investigations, Beverley C. Thompson

Emory Law Journal

Environmental cancer risks remain difficult to detect, investigate, and remediate despite decades of federal regulation under the Toxic Substances Control Act (TSCA). Cancer cluster investigations are designed to identify unusual patterns of cancer and their environmental causes, but fragmented authority, inconsistent methodologies, and narrow investigative frameworks routinely prevent these investigations from addressing population-level harms. By failing to detect and address cancer clusters, public health systems inadvertently perpetuate environmental injustices, disproportionately harming communities already underserved and overburdened by pollution.

These failures are not merely scientific but reflect legal and institutional design choices that determine which cancer risks are visible, investigable, and …

This capstone focuses on lung cancer, maternal mortality, and obesity to evaluate the structural and policy factors behind these disparities. Using a quantitative comparative research design, the study analyzes secondary data from sources including CDC WONDER, the Behavioral Risk Factor Surveillance System (BRFSS), America’s Health Rankings, and the March of Dimes. Data were analyzed in Excel to create comparative figures, benchmarking Kentucky’s outcomes against the U.S. average and four regional peer states: Tennessee, Indiana, Illinois, and Virginia. These states were chosen for their demographic and geographic similarities …

A Comparative Analysis Of Governance And Financial Frameworks In Public Transit Systems: A Case Study Of Lextran And Peer Transit Agencies, Kelin E. Beattie

MPA/MPP/MPFM Capstone Projects

Public transportation serves as a vital community "lifeline," providing essential mobility for the 45% of Americans without private vehicle access and generating a 5-to-1 economic return on investment. This research investigates a critical fiscal paradox within Lextran, the transit authority for Lexington, Kentucky: despite achieving a cost per passenger trip 22% lower than the national peer average, the agency faces a $25.95 million unfunded capital gap over the current five-year planning horizon. Utilizing a comparative case study methodology, this paper evaluates the "rules of the game"—the hybrid governance and fiscal frameworks—that influence long-term financial sustainability.

The study benchmarks Lextran against …

Allocation And Governance Of Opioid Response Funding In Rural Kentucky: A Case Study Of The Big Sandy Area Development District, Hayley M. Mccarty

MPA/MPP/MPFM Capstone Projects

The opioid epidemic continues to present significant public health, economic, and administrative challenges throughout the United States, with rural Kentucky experiencing some of the nation's highest rates of opioid-related morbidity and mortality.

Effectively responding to this crisis requires not only adequate financial resources but also transparent governance, coordinated implementation, and accountability for how public funds are distributed.

This study examines the allocation, governance, and implementation of opioid response funding within the Big Sandy Area Development District (BSADD), a rural multi-county region in eastern Kentucky. Using a qualitative case study and policy analysis approach, the research evaluates four primary funding sources: …

Should Kentucky Adopt A Formal Statewide Framework To Address The Local Fiscal Effects Of Tax-Exempt Public Universities On Host Communities?, Trina Shields, Catie Baumstark

MPA/MPP/MPFM Capstone Projects

Kentucky’s public universities provide significant educational, economic, and workforce development benefits to the Commonwealth. However, because these institutions are exempt from local property taxes, questions arise about the fiscal effects on the communities that host them. While the benefits generated by universities extend beyond municipal boundaries, the fiscal effects of tax-exempt property are often concentrated within host communities. As universities expand their campuses and acquire additional property, local governments may face increased demands for public services without a corresponding increase in property tax revenue.

This study examines whether Kentucky should adopt a formal statewide framework to address the local fiscal …

Defamation, Privacy, And The First Amendment: Cases & Problems (3rd Ed.), George Biashvili

Books

I created this resource in anticipation of teaching my Torts II class, which will primarily explore defamation and privacy torts. Though I searched for a suitable coursebook, I found that none contained all of the opinions I consider essential for teaching the nuances and complexities of these subjects. Additionally, I wanted to spare my students the exorbitant price tags associated with traditional law school texts. Hence, I assembled a collection of relevant privacy and defamation cases that align with the objectives of my course. Each case is accompanied by a set of questions to further stimulate class discussion. Where I …

Formal Neutrality And Unequal Liability: How Algorithmic Aversion Distorts Liability For Algorithmic Torts, Gao, Jingkang

Santa Clara Law Review

The shift in the cause of machine-induced harm from mechanical failures to algorithmic decision- making is challenging the applicability of products liability. Because algorithms now operate machines analogously to humans, a doctrinally coherent response is to subject algorithmic torts to a negligence framework that evaluates the reasonableness of decisions rather than the content of algorithms. This approach offers a theoretically grounded, formally neutral, and normatively appealing solution. In practice, however, it may result in unequal liability. Even under a negligence regime, algorithmic decision- makers may face systematically greater liability if injured parties are more inclined to pursue litigation against algorithmic …

Constitutional Structures In Private Law And The Example Of Waste Law, Fraley, Jill M.

Santa Clara Law Review

This Article proposes three criteria for when a private law mechanism performs a structural constitutional function: when it constrains present authority in the name of future stability, when it disperses enforcement to avoid centralized authority, and when it has structural entrenchment to avoid ordinary displacement. While many private law doctrines contain constitutional resonances or echo rights, the core of constitutional law is the power structure—a precondition for the protection of those rights. Constitutional structures have three key components: self-binding through time, separation and diffusion of power, and entrenchment beyond ordinary politics. For a private law doctrine to do more than …

Criminalizing Survival: How The Grants Pass Decision Is Intensifying The Homelessness Crisis In California And Beyond, Riley, Laura

Santa Clara Law Review

This article examines the intensifying criminalization of homelessness in the United States since the Supreme Court’s 2024 decision in Grants Pass v. Johnson, which removed the ability of people to challenge laws under the Eighth Amendment’s Cruel and Unusual Punishment Clause that prohibit survival behaviors in public places like sitting, sleeping, or lying down. The article explores the legal and practical challenges in documenting criminalization of homelessness, analyzes national and California-specific legislative trends and enforcement practices, and assesses the impacts on unhoused populations. The article concludes with policy recommendations to shift the state of homelessness criminalization from one of punitive …

Exploring Teachers’ Perceptions Towards Using Ict With Dialogic Teaching In The Primary Science Classroom In Saudi Arabia, Yousef Alharbi, Sue Johnston-Wilder

Journal of Educational Technology Development and Exchange (JETDE)

This study examines the implications of teachers’ perceptions of using ICT to support dialogic teaching in primary science classrooms in Saudi Arabia. It employed questionnaires distributed electronically to science teachers working in state primary schools in Riyadh, and 305 completed responses were analyzed using SPSS. The majority were found to implement a variety of activities to support dialogue and to use several ICT tools in their science lessons. In addition, most teachers reported positive attitudes toward ICT, dialogic teaching, and ICT-supported dialogic teaching in science lessons. However, the results indicated that some teachers currently adopt a dominant role in dialogue …

Methods For Mapping Europa’S Bands Through Time, Liam Hodgson

IdeaFest 2026

Of the Galilean moons circling Jupiter, Europa is the second closest and the smallest. It has attracted some interest from the scientific community, due to its subsurface ocean which is one of the most likely places to find life in our solar system, and its geologically young surface of ~100Myr. We use stratigraphic relationships as a means to understand the evolution of Europa’s ice shell surface over time. Tectonic motion drives changes in surface morphologies, divergence of the plate creates dilational features like bands and ridges, and convergence may cause subduction-like processes. We use ArcGIS to map and categorize surface …

Runner's High Or Running High, Whitney Ogle

IdeaFest 2026

Cannabis use has been associated colloquially with laziness, but inactivity in cannabis users has not been supported by research. In fact, more research is showing people are pairing cannabis with physical activity for a variety of reasons. The purpose of this study was to understand the prevalence of and cannabis use behaviors among distance runners who participated in the Avenue of the Giants 10k, 1/2 Marathon, and Full Marathon in Spring 2025. 42% of the sample of 151 participants reported consuming cannabis and 95% of the total sample reported they don't think athletes who test positive should be banned from …

Athletes Should Play More Sports : An Ecological Dynamics Perspective, Adam Garrison

IdeaFest 2026

This project looks at early sport specialization and its associated risks, including increased injury rates, burnout, and limited long-term athletic development. It highlights how repetitive, single-sport training can restrict adaptability and overall skill development in youth athletes. To combat this, the project explores ecological dynamics as an alternative approach. By emphasizing varied movement experiences, environmental learning, and adaptability, this approach promotes more holistic athlete development. The project ultimately argues that multi-sport participation naturally aligns with ecological dynamics and can help lessen the negative effects of early specialization.

Improving Suicide Screening In Oncology: High-Risk Older Adults And Males, Dezeray Stevens

IdeaFest 2026

Suicide risk among patients with cancer is often overlooked, despite being significantly higher than in the general population, especially among older adults and males. In many inpatient oncology settings, screening is inconsistent and limited to admission, leaving changes in distress undetected. This quality improvement project proposes a structured, multilevel approach, including standardized screening, improved communication, and policy-driven protocols. Guided by the Johns Hopkins model, the goal is to improve early identification and timely intervention. Expected outcomes include increased screening consistency, better recognition of distress, and improved patient safety.
