Continuous Authentication For Industrial System Access: Evaluating Bluetooth Low Energy Direction Finding And Channel Sounding For Tailgating And Relay Attacks, Mitchell Mennelle

LSU New Orleans Theses and Dissertations

In physical access control, authentication is often viewed as a one-time event, where, once an authorized user crosses a protected boundary, downstream systems assume the user remains physically present. Tailgating and relay attacks violate this assumption. In this thesis we propose a continuous authentication layer based on two Bluetooth Low Energy spatial signals. Angle of Arrival direction finding follows the trail of a worn credential to determine when an operator exits a work zone. Bluetooth Channel Sounding measures a physical property of the radio path and verifies distance during stationary periods. Limiting Relay Attacks with Event-Driven Distance Verification. A stream …

Evaluation Of Ostomy Pouching Change Practices Among Hospital-Based And Community-Based Nurses, Hannah Gerlach

All Theses

An estimated 725,000 to 1 million Americans are living with an ostomy and depend on ostomy pouching systems as part of their daily care. Effective ostomy management requires regular pouch changes and consistent skin care to prevent peristomal skin complications. Many individuals living with an ostomy face long-term challenges in managing their ostomy care, which can negatively affect their health-related quality of life. There is a need to understand how professional experience across different care environments, such as hospital-based and community-based settings, influences ostomy nursing care practices.

This study evaluates how nurses working in hospital-based settings and community-based settings perform …

Electrokinetic Flow Instabilities In Non-Newtonian Fluids With Conductivity Gradients, Md Mainul Islam

All Theses

Electrokinetic instabilities (EKI) arise in electrically driven flows because the applied electric field interacts with spatial variations in electrical conductivity, generating electric body forces that can destabilize fluid interfaces. EKI can be beneficial by enhancing mixing in microchannels where diffusion is slow, but it can also be detrimental by disrupting stable sample transport, focusing, and separation. EKI has been widely studied in Newtonian fluids, and the electric Rayleigh number is known to govern the onset of this instability. However, very few studies have examined its behavior in non-Newtonian fluids, despite their prevalence in biological, chemical, and industrial applications. 

This thesis …

Flames And Fluids: Design Motivations For Painterly Stylization Of Effects, Nathaniel R. Edmonds

All Theses

Visual effects are widely used in animated media to immerse the audience, direct attention, and guide the perceptions and emotional responses to the world and characters therein. In these uses, effects act as narrative elements in a film. Visual effects can include weather (e.g., fog), visually distinct materials(e.g., water), and other visually interesting physical phenomena (e.g., fire or the fracturing of an object). Contemporary animations and, by extension, their animated effects are increasingly being produced in carefully crafted styles, ranging from the comic-book posterization seen in the Spiderverse franchise of animated films, to the painterly stylization of Puss in Boots: …

What Makes A Cozy Game Cozy? Looking Through The Lens Of Feminism And 4e Cognition, Mary Catherine M. Wilcox

All Theses

Why do some games feel cozy, and others miss the mark, even if they are tricked out in bright colors and festooned with bows? This thesis examines the emerging genre of “cozy games” to better understand why some titles successfully evoke comfort and relaxation while others fail, despite relying on conventionally cute aesthetics or farming-sim mechanics. Although cozy games have grown rapidly in popularity over the past decade, the genre remains under-studied and is often dismissed as frivolous, reflecting the broader historical devaluation of media associated with women. Accordingly, this study argues that understanding cozy games requires examining women’s relationship …

Trace Element Concentrations In Tissues And Otoliths Of Fishes From Artificial Reefs In The Northern Gulf Of Mexico: The Role Of Size, Age, And Trophic Position, Blaine Savoie

LSU New Orleans Theses and Dissertations

Nearshore artificial reefs and fishes relying on them to forage and refuge can be susceptible to trace element (TE) pollutants from anthropogenic sources. Although some TE are essential, higher concentrations can cause detrimental effects and concern regarding consumption. This study assesses TE accumulation in nearshore reef fishes in the northern Gulf of Mexico, a region influenced by coastal riverine discharge, where fishing has socioeconomic importance. Five fish species from six eco-reefs were collected and analyzed for TE. An inductively coupled plasma mass spectrometer was used to analyze the TE concentrations of muscle, liver, and otoliths. TE concentrations of tissues and …

Comparative Analysis Of Rigging Implementations, John E. Thomas

Master of Fine Arts in Digital Media Culminating Experience

Rigging acts as a bottleneck between modeling and animation, yet core rigging principles and procedures have largely stagnated over the past two decades. However, cutting-edge rigging systems have begun appearing recently in software not typically used for animation. These tools are proposed to mitigate the need for rigging artists. These novel systems now force teams to evaluate what system is best for their projects. Artists have focused their analysis of rigging tools on how they interact with, or compare to, existing pipeline structures, concepts, and deadlines. This research centers on the implementation and development of tools and systems ranging from …

Artificial Intelligence (Ai) In Forensic Psychology: An Umbrella Review Of Potentials And Pitfalls, Ysabel Thereze Ang Guevarra, Nur Eva Alisha Binte Mohamed Hisham, Andree Hartanto

Research Collection School of Social Sciences

Artificial intelligence (AI) is becoming increasingly embedded within forensic psychological practice, shaping how criminal risk, legal responsibility and public safety are assessed. AI tools are now used in recidivism prediction, behavioural analysis, deception detection and investigative support, high-stakes domains where errors can have profound consequences. Despite this rapid adoption, the existing literature remains fragmented, with most reviews confined to narrow subdomains and offering limited integrated synthesis of AI′s broader role in forensic psychology. Thus, this umbrella review addresses this gap by synthesising findings from 43 reviews obtained from five major databases, namely EBSCOhost ERIC, EBSCOhost PsycInfo, PubMed, Scopus and Web …

Gender And Professional Identities In Businesswomen’S Negotiation, Chi-Ying Cheng, Amy J. Lim, Yi Wen Tan, Fiona Lee

Research Collection School of Social Sciences

Gender roles and expectations for women have been shown to account for why women tend to negotiate ineffectively in business settings. Drawing from the psychological literature on multiple identities, this paper examines how individual differences in perceived compatibility between gender and professional identities–captured by the construct Gender-Professional Identity Integration (G-PII)–shape businesswomen’s negotiation behaviors. Two studies examined how G-PII interacts with identity cues and cue valence to influence negotiation outcomes. We found that those who perceived their gender and professional identities as compatible (high G-PII) exhibited an “assimilation” effect–they negotiate more effectively when their professional identity was primed by professional identity …

Misplay Or Malice? Players’ Interpretations Of Poor Gameplay In Competitive Team-Based Multiplayer Online Games, Valerie Yu, Benjamin H. Detenber, Sonny Rosenthal

Research Collection College of Integrative Studies

Research on perceptions of gaming toxicity has focused on its verbal forms, while gameplay-related forms remain relatively understudied. Furthermore, assessments of gameplay actions as toxic may depend on situational considerations. The present study used a controlled experiment to examine player interpretations of gameplay sabotage using pre-recorded gameplay scenarios from the game, League of Legends. We found that the presence of gameplay sabotage elicited stronger negative emotions and triggered greater player-reported intentions to retaliate and correct the offending player than in comparable instances of unintentional poor gameplay. Further exploratory analyses suggested that participants rated poor gameplay as less acceptable in more …

OES Theses and Dissertations

Tidal flooding is an increasingly pressing hazard in coastal Virginia due to sea level rise and land subsidence. The Hampton Roads region of Virginia has the second-highest rate of relative sea level rise in the United States and experiences frequent tidal flooding, but the water quality impacts of this flooding on the Chesapeake Bay are not being accounted for. High concentrations of dissolved nutrients and Enterococcus bacteria (a fecal indicator) have been observed in tidal floodwater of the Lafayette River, a tributary of the James River and the lower Chesapeake Bay. This study investigates variability in dissolved nutrient and Enterococcus …

Drones In Wildfire Airspace Management: Developing A Scalable Framework For Mid-Sized Cities, Victoria Denise Tanner Williamson

Engineering Management & Systems Engineering Theses & Dissertations

Wildfires are becoming increasingly frequent and severe, creating growing risks for mid-sized communities with limited emergency response resources. The January 2025 Los Angeles wildfires—which burned more than 57,000 acres and destroyed over 18,000 structures—underscore the urgent need to strengthen wildfire response strategies through the integration of unmanned aerial systems (UAS) (Hardy, 2025).

This study develops a scalable framework for drone-assisted wildfire response in resource-constrained environments. Using the city of Waynesboro, Virginia, as a case study, the research examines how mid-sized jurisdictions can integrate unmanned aerial vehicles (UAVs) to improve preparedness, response, and recovery. A three-round, mixed-methods Delphi study engages emergency …

The Effects Of Working With Unidentified Migrant Remains: Caregiving, Border Security, And Human Rights On The U.S.–Mexico Border, Jennifer Delaine Huddleston

Graduate Program in International Studies Theses & Dissertations

This dissertation explores how migrant death and the handling of unidentified remains operate within U.S. border governance, focusing on caregivers, forensic anthropologists, and volunteer search-and-recovery teams who recover, document, and try to identify the dead along the U.S.–Mexico border. Using classic grounded theory and reflexive visual ethnography, the study includes interviews, field observations, and documentary photography conducted in South Texas, covering Brooks, Maverick, and Webb Counties.

Instead of viewing migrant deaths as accidental humanitarian tragedies, this dissertation situates caregivers’ daily work within a historical trajectory of deterrence-based border policies, from Prevention Through Deterrence to modern state-led enforcement regimes. It demonstrates …

Naturalistic Classroom And Home Practices To Support Executive Function And Self-Regulation Of Typically Developing Preschool Children Between The Ages Of 3-5 Years Old: A Mixed Method Study, Michelle Ann Burek

Rehabilitation Sciences Theses & Dissertations

Executive function (EF) and self-regulation (SR) are foundational developmental processes supporting young children’s participation in play, learning, social relationships, and everyday occupations. Although important to school readiness, social competence, health, and well-being, these skills are often examined in structured settings rather than the natural environments in which children develop. Guided by ecological, developmental, and occupational therapy perspectives, this dissertation examined EF and SR within children’s everyday participation and explored caregiver and teacher roles in supporting these processes.

This dissertation consists of three interconnected studies. The first was a systematic review of peer-based interventions to improve social participation among children and …

Menopausal Symptoms, Psychosocial Factors, And Physical Activity Among Physically Active Midlife Females, Ella Onsoriasl

Exercise Science Theses & Dissertations

Menopausal symptoms are common during midlife and may be associated with females' physical activity (PA) participation, yet how these symptoms relate to PA levels, perceived confidence and enjoyment, and psychosocial resources such as social support (SS), exercise identity, and quality of life (QOL) remains unclear. The purpose of this study was to examine how menopausal symptom severity relates to PA levels, perceived confidence and enjoyment during PA, and psychosocial factors, including SS, exercise identity, and QOL. This cross-sectional study surveyed 151 midlife females aged 40 to 60 who reported engaging in intentional PA at least once per week. Participants completed …

Counselors’ Training Needs In Effectively Engaging With Psychedelic-Assisted Therapy, Elif Bor

Counseling & Human Services Theses & Dissertations

As public and scientific interest in psychedelic-assisted therapy (PAT) continues to grow, counselors are increasingly encountering clients who are exploring or engaging in psychedelic use for therapeutic purposes. Such encounters introduce new ethical, clinical, and professional considerations. Counselors must develop an informed understanding of psychedelics and their effects, recognize the emotional and cognitive processes that may emerge during psychedelic experiences, and be prepared to respond to potential risks or adverse reactions (Aicher et al., 2025). They also need to competently answer client questions, assess risk and suitability, facilitate the integration of psychedelic experiences, and collaborate with medical and other professionals …

Empirical Rhetorical Modeling: New Analytical Tools To Evaluate The Intensity Of Rhetoric, August Immel

English Theses & Dissertations

Since 2020, the United States has experienced a surge of incendiary rhetoric in contemporary political discourse, which exacerbates societal polarization and incites violence as evidenced by heightened politically motivated attacks. Numerous actors characterize the impetus of such violence as “extreme rhetoric.” No standard definition exists for such a term, and this gap necessitates the central research question of this dissertation, which interrogates how rhetoric can be systematically evaluated for “extremeness.” I propose that the issue of extreme rhetoric can be fruitfully examined from within the context of rhetorical theory, but instead of attempting to create a new definition of “extreme …

Experimental Investigation Of The Discharge Modes Of Nanosecond Pulsed Plasmas At Atmospheric Pressure, Md Ziaur Rahman

Electrical & Computer Engineering Theses & Dissertations

The generation of repeatable and stable nanosecond pulsed atmospheric pressure plasmas is important to non-thermal plasma applications in various fields including medicine, material processing, food processing, and plasma ignition for combustion. This dissertation investigates the atmospheric pressure plasma initiation and formation under 10 – 200 ns pulsed power for electrode configurations applicable for transient plasma ignition (TPI) for combustion. The impacts of pulsed power parameters, gas condition, and electrode geometry on the discharge initiation and modes (i.e., streamer, transient spark and spark) are systematically evaluated for applying TPI for combustion. We evaluated the discharge modes driven by both longer and …

Switches And Witches: Exploring The Relationships Between Religious Struggles, Spiritual Beliefs, And Well-Being, Emma J. Trierweiler

Psychology Theses & Dissertations

This study examined the mechanisms between interpersonal and doubt-related struggles and well-being outcomes in a formerly religious sample. The focus of this dissertation was to analyze the mediating roles of disengagement from God and perceived social support. Approach toward God was also examined as a control but not specified to be connected to the well-being outcomes given the emphasis on formerly religious individuals’ experiences. This was a retrospective study, where participants were asked to consider their responses as they relate to the time they were pulling away from religion. Three measures of well-being were explored using structural equation modeling. Positive …

'We Will Be Here': Modeling Hunting Community Narratives In Avanersuaq, Greenland, Talor Stone

Graduate Program in International Studies Theses & Dissertations

The Inughuit, a small Indigenous population in Northwest Greenland with a rich history of subsistence hunting in one of Earth’s harshest environments, have long been portrayed in Western media and academic literature as symbols of vulnerability and resilience, often depicted more as icons of climate change and a culture under threat than as actual people with hopes and aspirations. Indigenous voices are strikingly absent from these Western accounts.

As the Arctic gains prominence amid rapid growth in climate discourse, regional geopolitics, and tourism, the implications of these representations become increasingly significant. When Western crisis narratives dominate discourse and shape regulatory …

Towards More Realistic And Practical Graph Backdoor Attacks, Jiawei Chen

Computer Science Theses & Dissertations

Graph Neural Networks (GNNs) have demonstrated remarkable performance on graph-based learning tasks and are increasingly deployed in security-critical applications. However, recent studies have shown that they are highly vulnerable to graph backdoor attacks (GBAs), where adversaries implant malicious triggers to induce targeted misclassification during inference. Despite their effectiveness, existing GBAs are often developed under unrealistic assumptions, such as focusing exclusively on simple homogeneous graphs or assuming the adversary possesses privileged access to target nodes during inference. This dissertation aims to systematically investigate and design graph backdoor attacks under significantly more realistic graph settings and adversarial constraints.

First, we investigate the …

Exploring The Determinants Of User Discontinuance In Ai-Driven Usage-Based Insurance, Wenzhuo Li

Theses and Dissertations in Business Administration

While interest in algorithmic decision-making continues to grow, limited research has examined the post-adoption phase. This study examines how users evaluate their post-adoption experiences with algorithmic decision-making in the context of usage-based insurance (UBI), focusing on how expectation disconfirmation shapes satisfaction and the intention to discontinue use. It explores two key questions: What factors influence users’ discontinuance intention toward AI-based UBI systems? And how do specific algorithmic characteristics alter how users form these post-adoption evaluations? To investigate these questions, this study develops a comprehensive theoretical model that integrates the Expectation Confirmation Model and Reactance Theory, incorporating additional factors such as …

Drinking Group Injunctive Norms: An Event-Level Examination, Karolina Kazlauskaite

Psychology Theses & Dissertations

College students are at increased risk for negative alcohol-related outcomes. Theoretical and empirical support suggest that peer groups play a crucial role in college student alcohol use, in part because they establish normative values and behaviors (i.e., norms) that members follow. Research indicates that those who identify more strongly with a group are more likely to embody that group’s values—particularly regarding drinking. Notably, injunctive norms, or perceptions of peer permissibility toward drinking, predict individual drinking outcomes, such that perceiving one’s peers as more approving confers additional risk for personal drinking. However, prior examinations of injunctive norms have not assessed perceptions …

Lgbtq People's Lives Post-Incarceration: A Multi-Method Study, Hayley Jackey

Sociology & Criminal Justice Theses & Dissertations

LGBTQ people are disproportionately targeted by the criminal legal system and overrepresented in the carceral system. Despite current research in queer criminology examining the impacts of the carceral system on the community, there is a dearth of literature examining LGBTQ people’s experiences or identity disclosure once released from the Prison Industrial Complex and into the Prisoner Reentry Industry. Using unique methodologies of photo-elicitation interviews and in-depth interviews, the current study examines how ten formerly incarcerated LGBTQ people navigate returning to society post-incarceration. The study found two distinct experiences. The first group was selective about who they shared their LGBTQ identity …

Communication & Theatre Arts Theses

In 2018 ESPN debuted its national streaming service ESPN+. This profoundly changed the way sports fans watch college sports as well as other professional sporting events. Prior to ESPN+, a limited number of college sports games appeared on linear channels such as ESPN, ESPN2 and ESPNU, and occasionally a few other channels. Since 2018, ESPN+ streamed thousands of events per year ranging from college soccer to college softball and everything in between, including the qualifying and early rounds of professional tennis and golf tournaments from around the country. This case study describes the impact of ESPN+ on a college conference, …

Exploring The Experiences Of Women In Mental Health Therapy After The Occurrence Of Perinatal Loss, Courtney Allison Nishnick

Counseling & Human Services Theses & Dissertations

Perinatal loss encompasses losses of pregnancies at any gestational age, as well as deaths occurring within one year post-birth. In the United States, around 40 thousand stillbirths and infant deaths occur every year (Ely & Driscoll, 2025; Gregory et al., 2025), with about 23 million miscarriages also occurring annually worldwide (Quenby et al., 2021). Perinatal loss experiences lead to distressing mental health symptoms not limited to anxiety, depression, posttraumatic stress, and grief (Crockett et al., 2019; Wamser & Ferro, 2025). While there is extensive research on perinatal loss as it pertains to medical context, there is minimal research relating to …

Two Essays On Designing Conversational Agents: Varying Level Of Mimicry And Personality–Brand Congruence, Sama Ashouri

Theses and Dissertations in Business Administration

Across two essays, this dissertation demonstrates that mimicry and personality shape consumers’ perceptions of chatbot intelligence, creativity, and fit, with downstream effects on recommendation acceptance that depend on factors such as mimicry intensity, brand familiarity.

Essay1: Mimicry, a central aspect of human interaction, is increasingly being examined in human–AI communication, particularly with chatbots. While prior research shows mimicry can build rapport, trust, and engagement, it has often been treated as a binary factor, overlooking how different levels may influence user perceptions. This research proposes and tests a dual-mediation framework in which different levels of chatbot mimicry affects recommendation acceptance through …

Effects Of Beverage Color During Mouth Rinsing On Measures Of Muscular Endurance, Muscular Strength, And Exercise Perceptions During Isometric Handgrip Testing, Sydney Andrews

Exercise Science Theses & Dissertations

Previous research has shown that color can influence psychological responses, physiological responses, and exercise performance. These effects have been previously attributed to learned associations or expectations which may influence exercise-related outcomes. This study aimed to investigate whether beverage color influences muscular performance during intermittent isometric handgrip exercise. This randomized, single-blind, deceptive crossover study consisted of 34 physically active adults (21.9±3.1 years) who completed a handgrip endurance test under three conditions: red beverage rinse, clear beverage rinse, and no-rinse. Participants were informed that the study would examine the effects of mouth rinsing two commercially available carbohydrate containing sport drinks on muscular …
