Bruen, Levels Of Generality, And Our Historical Tradition Of The Regulatory “Why”, Kevin K. Wang

UC Law Constitutional Quarterly

To pass Second Amendment muster under New York State Rifle & Pistol Association v. Bruen, gun laws encompassed by the Amendment’s plain text must align with our nation’s historical tradition of firearm regulation. A challenged law comports with history and tradition when it is sufficiently analogous to historical regulations along two metrics: “how” and “why” the regulation burdens the right to keep and bear arms.

One glaring ambiguity leftover from Bruen is the level of generality at which courts, when analogizing between laws past and present, must frame a regulation’s “how” and “why”—an issue of major consequence. Characterizing the “how” …

The Body At The Mercy Of The State: Sama V. Hannigan And The Fragmented Right To Refuse Across State Lines, Mallory Yeates

UC Law Constitutional Quarterly

Courts have long recognized bodily autonomy as a core constitutional value. Yet, doctrine governing reproductive healthcare tells a different story. Sama v. Hannigan exposes the fragility of the right to refuse medical treatment, particularly for incarcerated patients whose claims must survive the demanding standard of qualified immunity. When physicians removed Carrie Rahat Sama’s ovary despite her explicit refusal, her constitutional claim failed because no precedent with sufficiently similar facts had previously condemned such conduct. This case reveals how the “clearly established” prong of qualified immunity can foreclose redress for blatant violations of autonomy.

This Note argues that the viability of …

Accelerated Coupled Mode Model For Fiber Laser Amplifiers As An Averaged Dynamical System, Rebecca Bryant, Jacob Grosek, Jay Gopalakrishnan

Mathematics and Statistics Faculty Publications and Presentations

We apply a known theorem for simplifying dynamical systems with bounded error to a specific optical fiber waveguide problem, thereby supplementing the physical intuition and heuristics used in the optics community with proper mathematical justification. Using techniques from the averaging theory of dynamical systems, a reliable accelerated model based on the coupled mode theory (CMT) approach for a common fiber laser amplifier application is derived. Computational testing reveals that this accelerated model achieves a ∼4000x increase in computational speed compared to the CMT model while preserving high accuracy in key figures of merit such as output power and amplification efficiency. …

Rethinking Consumer Data And Behavior, Nicole J. Olynk Widmar, Michael L. Smith, Erin Robinson

Purdue University Press Books

Today’s food and agricultural consumers are driven by more than just price—they are influenced by trust, values, and perceptions that are often difficult to measure. Rethinking Consumer Data and Behavior explores what truly shapes consumer choices and how businesses can respond effectively.

This book utilizes research on loyalty, risk, sustainability, and ethical considerations, revealing how these factors influence purchasing decisions in ways traditional data often misses. It examines consumers’ willingness to pay for local and organic products, the impact of food labeling and safety messaging, and the surprising role of sensory cues such as appearance and taste. The book also …

Understanding Contest Skill To Reduce The Welfare Costs Of Aggression, Lucy Oldham, Gareth Arnott, Mark Briffa, Agnieszka Futro, Jo Donbavand, Alena Kadlecova, Ali Alameer, Manzar Malik, Mhairi Jack, Iona Smith, Mark Brims, Claire Anderson, Simon P. Turner

School of Biological and Marine Sciences

Skill is the ability to do a challenging behaviour well. We examined how contest skill influences contest success, costs and whether skilful behaviour enhances welfare. We measured skill across three domains: accuracy, appropriateness (selecting suitable agonistic tactics when the optimal choice varies) and efficiency, alongside vigour, sex and body weight. Skill was weakly correlated across domains. Winners were heavier relative to their opponent, displayed greater vigour and were more skilful at blocking, but other skill measures did not predict contest win/loss outcome. Appropriate blocking by winners reduced the number of lesions received by reducing exposure to attacks, suggesting it can …

Biophysical Insights Into A Cryptic, Hydrophobic Binding Site On Pcna, Alexis Dispensa

Theses and Dissertations

Proteins are dynamic molecules whose functional landscapes extend beyond static structural representations. Transient cryptic pockets (buried cavities that emerge through protein motion) represent underexplored targets for allosteric regulation and drug discovery. General anesthetics are small, lipophilic, weakly polar molecules that are well suited to partition into such hydrophobic sites. In this work, environment-sensitive fluorescence, photoaffinity labeling, mass spectrometry, mutational analysis, and microsecond molecular dynamics simulations were integrated to discover and characterize a cryptic, highly apolar binding site within the hydrophobic core of human proliferating cell nuclear antigen (PCNA), a central scaffold in DNA replication and repair. Using the solvatochromic fluorescent …

Family Processes As A Protective Factor Between Adverse Childhood Experiences And Adolescent Delinquency, Tessa Johnson

Theses and Dissertations

This study explores whether family processes (i.e., parental attachment and parental discipline/monitoring) serve as protective factors between the relationship of adverse childhood experiences (ACEs) and adolescent delinquency. Prior research has established an association between ACEs and many negative life outcomes, including delinquent behavior, while strong parental attachment and parental discipline/monitoring are linked to lower rates of delinquency. However, the interplay of these three factors has been understudied. Drawing on data from the 2024 Florida Youth Substance Abuse Survey (FYSAS) (N=22,016), this study examines the relationship between ACEs, family processes, and delinquency using negative binomial regression models. Results indicate that parental …

Development Of An Experimental Platform For Hydrogen-Propelled Cold Spray, Michael James Katz

Theses and Dissertations

Cold spray (CS) has gained recent interest as an additive manufacturing process. This process uses high pressure propellant gas to accelerate solid-state powder particles through a specialized nozzle, beyond which the powder deposits onto a substrate as a dense coating and without either material undergoing a phase change. Both nitrogen (N2) and helium (He) are commonly used as CS propellants, with He generally yielding superior results at otherwise similar processing conditions. However, performance advantages of He come with a significant drawback: He is a limited resource that may be sensitive to geopolitical conflicts and, in recent history, has been subject …

Independent panel inclination methods calculate the pressure distribution on the surface of a hypersonic vehicle. Normal shock relations provide the thermodynamic state on each panel. Streamlines are integrated using closed-form streamline equations. Flat plate formulas corrected for compressibility calculate the skin friction coefficient and acreage heat flux on each panel. Formulas …

The Role Of Avoidance In The Relationship Between The Impact Of Childhood Trauma And Physiological Responsivity To Fear And Reward In Adulthood, Tristan Alana Benjamin

Dissertations (1934 -)

Childhood trauma is prevalent and has been associated with deleterious physical and psychological outcomes that persist into adulthood. Extensive research on the neurobiological consequences of experiencing trauma has demonstrated an association between experiencing a traumatic event and elevated physiological arousal in response to fearful stimuli compared to healthy controls. By contrast, emerging research has found that adults who experienced a traumatic event during childhood demonstrate blunted physiological arousal responses. The physiological profile associated with childhood trauma may be related to coping strategies utilized; notably, children may be more likely to engage in avoidance to cope with the impact of trauma …

From Awe To Anxiety: Investigating Art-Induced Self-Transcendence Using Virtual Reality, Monica V. Weedman, Kutter Callaway, Daniel M. Shafer, Tyler Greenway, Jo- Ann Tsang, Wade C. Rowatt

University Faculty Publications and Creative Works

Introduction: Art has been shown to evoke a range of emotions, yet the mechanisms underlying these responses remain underexplored. Across three studies using between- and within-subjects designs, we examined how viewing original photographic art in virtual reality (VR) influences self-transcendent emotions and related affective states.

Method: In Study 1, participants viewed photographs in one of three VR contexts (museum, warehouse, church sanctuary). In Study 2, participants viewed the same photographs in a VR museum context where the photo scale varied (small vs. large scale). In Study 3, online participants viewed video recordings of the VR museum with or without computer-generated …

Growing Healthy Habits: Impacts Of A Youth Community Garden For Children In Rural Mississippi, Olivia G. Degravelle

Honors Theses

This study examines the implementation and outcomes of a Youth Garden Program conducted in Pontotoc, Mississippi. Funded by the Allstate Community Service Project Grant, the Youth Garden was constructed within the previously established Pontotoc Community Garden. The initiative comprised four weekly workshops designed for participants ranging from preschool to adolescence. Each session incorporated hands-on fruit and vegetable (FV) planting or harvesting, an educational lesson, and a complementary craft activity. Children’s FV consumption patterns, nutritional knowledge, and attitudes toward FV were assessed through pre- and post-program surveys. In addition, the photo-elicitation interview method invited participants to take digital photographs of garden …

Emotional Awareness And Resilience In Adolescents, Emilie Zimmerman

Master's Theses (2009 -)

Adolescent trauma exposure is prevalent and associated with a range of negative developmental outcomes. However, some youth demonstrate resilience. Emotional awareness, a foundational component of emotion regulation, may play a role in promoting adaptive functioning following adversity, though its contribution to resilience in trauma-exposed adolescents remains unclear. The present study examined whether emotional awareness is associated with multiple domains of resilience including prosocial behavior, self-efficacy to handle conflict, perceived resilience, and emotional and conduct problems, after accounting for trauma exposure. Participants were 36 adolescents enrolled in a support program for at-risk youth. Data were obtained from youth-report measures of trauma …

Good Resource, Bad Vibe: How Well Does The Media Reflect Economic Activity?, Brett Watson, Noah Burke, Dayna Jean Defeo

ISER Reports

Resource industries like oil and fishing are characterized by boom-and-bust cycles – there are “good years” and “bad years.” In communities that are highly connected to a particular resource, these economic shocks are foregrounded in the public attention. This paper compares economic indicators with media coverage over a 10-year period in Homer, Alaska. Specifically, it explores the economic shock of the 1989 Exxon Valdez oil spill and looks at how media coverage aligned to the fishery performance during the recovery years. Even as the fishery recovered to pre-spill performance in dollars, the media sentiment did not “bounce back” as quickly. …

Social Work Doctoral Dissertations

Master of social work (MSW) students may be entering into field practice without meeting the necessary competencies for practice to address the needs of the gender and sexuality diverse (GSD) population. The literature supports that GSD content may be absent from course content. This cross-sectional design study aimed to understand what factors influence MSW faculty to incorporate GSD content into their coursework. MSW faculty at Council on Social Work Education (CSWE, 2022) accredited programs were invited via email to complete an online, anonymous, and voluntary survey. The results suggested strong support for the integration of GSD content into the coursework, …

Mapping Serial Killer Life Pathways With Behavior Sequence Analysis, Morgann Lynn Brafford

Walden Dissertations and Doctoral Studies

Although adverse childhood experiences (ACEs) are known to influence criminal behavior in adulthood, their potential influence on serial killer actions has not been scrutinized. This study was an investigation of how ACEs might affect serial killer actions later in life. The trauma-control model provided a conceptual framework for the investigation. Marono et al.’s research featuring behavior sequence analysis (BSA) was broadened to examine the impact of psychological abuse, sexual abuse, physical abuse, violence against animals, head injury, and bullying serial killer behaviors like stalking or sexual assault. The participants were 364 anonymized male serial killers from the Radford/Florida Gulf Coast …

Evaluating Sand Characteristics And Their Influence On Sea Turtle Nest Incubation Conditions, Thomas Naylor

Honors Theses

The embryonic development of sea turtles is strongly influenced by the environmental factors experienced during incubation within the nest. These environmental factors can influence hatchling sex ratios, body condition, and their success emerging from nests. Adult female sea turtles lay nests across a range of sites throughout the nesting season, resulting in each nest encountering unique abiotic conditions. This study aims to identify how variation in sand characteristics, such as grain size proportions, permeability, and color, influences nest temperature and subsequent hatchling outcomes of Loggerhead Sea Turtles (Caretta caretta) and Green Sea Turtles (Chelonia mydas) from …

Understanding The Alternative Normative Concepts, Dewitt W. Spiller

Theses

Matti Eklund's challenge to normative realism in Choosing Normative Concepts (2017) turns on the possibility of "alternative normative concepts"—concepts that play the same normative role as ours but have different extensions. Eklund argues that the ardent realist cannot express what he calls “the further question” about which concepts to use without either trivializing the answer or changing the subject. I argue that this challenge rests on an unstated assumption about how normative concepts are differentiated. I call this the Fragility Assumption. What I seek to show is that this assumption is not obligatory; there are live views of normative concepts …

Dimensionless Ratios And Processes Controlling Volumetric Bioretention Performance, Andrew Charles Hiestand

Master's Theses (2009 -)

Urbanization of previously natural land cover has spurred the innovation and implementation of green stormwater infrastructure (GSI) to combat increased surface runoff due to impermeable areas and a changing climate. Bioretention has been a popular choice in design due to its small footprint and proven effectiveness in retaining stormwater runoff and limiting discharges to receiving surface waters. However, their event-to-event performance variability is difficult to explain due to a number of confounding and interacting influences that distort cross-site analyses including inter-event drying and antecedent soil moisture conditions, geometric size and media properties, and event magnitude. This study applies and evaluates …

Cybersecurity Integration In Research Stage Connected Devices Within Healthcare Environments, Klemens Koszarek

Master's Theses (2009 -)

The rapid growth of connected devices in healthcare environments has significantly expanded the cybersecurity threat landscape, extending the potential risks beyond traditional hospital networks. Regulatory guidance from the FDA and risk management frameworks such as the NIST Cybersecurity Framework (NIST CSF) provide an approach for managing cybersecurity risk in connected systems. However, these principles are not always applied during early stages of device development. As a result, security consideration may be deferred until later stages of development, allowing for vulnerabilities to persist in systems as they move toward clinical or commercial deployment. This study presents a structured method for integrating …

Structure-Property Relationships In Chalcones With Extended Π-Conjugation: Ict Perturbation And Far-Red Fluorescence, Yi Pang, Christopher J. Ziegler, Wei-Yuan Chen, Paityn Houglan

University Research

4-Dimethylamino-2′-hydroxychalcone (DHC) derivatives are known to exhibit distinctive photophysical properties for various applications, including highly fluorescent crystals and molecular imaging. In a continuous effort to establish the structure–property correlation of this class of materials, a series of methoxy-substituted chalcone derivatives with extended π-conjugation have been synthesized to understand the effect of methoxy substituents on the intramolecular charge transfer (ICT) along the backbone. These derivatives displayed low fluorescence in protic solvents (e.g. ϕfl ≈ 0.003–0.009 in H2O), but high fluorescence in a polar aprotic solvent (ϕfl ≈ 0.2–0.35 in DMSO), with emission maxima up to 658 nm. Fluorescence lifetime measurements revealed …

Empowering Futures: Inspiring Young Girls In Stem Through Comics, Angel M. Griggs

Honors Theses

Women have historically been underrepresented in STEM fields. In my analysis, I explored how children’s literature representing historical women role models empower young girls to possibly pursue STEM careers. I applied Vekiri’s et. al (2024) research on attracting girls to STEM through interactive video games displaying STEM role models to comic books. In this project, I review academic literature, historical sources, and research articles to develop an educational comic book about historical women in STEM to help support the idea that creative activities and resources displaying role models can be influential to young children, specifically young girls. I focused on …
