Trauma-Related Compulsions In Obsessive-Compulsive Disorder: Functional Insights From Factor Analysis, Caitlin M Pinciotti, Max Thorsson, Gregor Horvath, Matti Cervin

Faculty, Staff and Students Publications

Resisting obsessive-compulsive disorder (OCD) compulsions is a key predictor of exposure and response prevention (ERP) effectiveness, yet trauma-exposed individuals with OCD endorse more severe compulsions and are more likely to be labelled 'treatment resistant.' Among trauma-exposed individuals, compulsions are theorised to function to prevent future trauma and cope with trauma-related responses. Recent findings suggest that certain compulsions in the context of trauma exposure differentially impact treatment outcomes, yet missing from extant literature is a larger empirically derived conceptualisation for how trauma may impact the underlying function of compulsions. In a sample of 662 adult patients enroled in intensive OCD treatment …

Reshaping Church Culture To Reflect The Imago Dei: A Genesis-Rooted Case Study Of Female Identity And Leadership In The Pacific Northwest, Cassandra Wilson

Doctor of Ministry (DMin)

Many Evangelical churches in the Pacific Northwest minister within a cultural environment marked by high individualism, religious disaffiliation, and contested narratives of gender and identity. This project explores how one Free Methodist congregation, Sage Hills Church in Wenatchee, Washington, has sought to embody a Genesis-anchored theological anthropology of imago Dei and ezer kenegdo in its leadership culture and congregational life. Using a qualitative case study design, the research examines how a single congregation navigates the tension between conservative church habits that restrict women’s roles and secular narratives that dissolve stable categories of gender. The study draws on an anonymous online …

Da Vinci Single-Port Transvaginal Natural Orifice Transluminal Endoscopic Surgery (Vnotes) Sacrocolpopexy: A Case Report And Literature Review, Xiaoming Guan, Chunhua Zhang, Qiannan Yang, Shunjia Hong, Wai Ieng Fong

Faculty, Staff and Students Publications

Pelvic organ prolapse remains a common condition requiring durable surgical correction, with sacrocolpopexy considered the gold standard. Transvaginal natural orifice transluminal endoscopic surgery (vNOTES) has emerged as a scarless minimally invasive approach, while the integration of robotic single-port technology may further enhance surgical precision and ergonomics. However, data on robotic-assisted single-port vNOTES (RSP-vNOTES) sacrocolpopexy remains limited. We report a case of a 58-year-old Asian woman with symptomatic apical pelvic organ prolapse. The pelvic organ prolapse quantification (POP-Q) assessment demonstrated stage II uterine prolapse. She underwent robotic-assisted single-port vNOTES (RSP-vNOTES) sacrocolpopexy using the da Vinci single-port (SP) platform. The procedure was …

Utility Of Diagnostic Arthroscopy Before Medial Patellofemoral Ligament Reconstruction In Pediatric And Adolescent Patients Without Articular Findings On Magnetic Resonance Imaging, Holden Archer, Kaleb Patterson, Jonathan D Schwartzman, Scott D Mckay, Indranil Kushare

Faculty, Staff and Students Publications

BACKGROUND: Medial patellofemoral ligament (MPFL) reconstruction is frequently used to manage recurrent patellar instability. Diagnostic arthroscopy is commonly performed before MPFL reconstruction to identify, confirm, and address intra-articular pathology. However, when preoperative magnetic resonance imaging (MRI) does not demonstrate intra-articular lesions, it is unclear how often diagnostic arthroscopy in pediatric patients alters surgical management.

PURPOSE: To determine the utility of diagnostic arthroscopy in young patients undergoing MPFL reconstruction who had no intra-articular chondral or osteochondral pathology, meniscal tears, or loose bodies identified on preoperative MRI, and to characterize intra-articular pathology detected on arthroscopy but not identified on MRI.

STUDY DESIGN: …

Empathy, Compassion Fatigue, And Resilience In Central Florida Firefighters And Ems Personnel, Lisa M. Correll

PhD in Education

The purpose of this nonexperimental quantitative study was to determine the relationship between empathy, compassion fatigue (CF), and resilience in firefighters and EMS personnel. Career firefighters and EMS personnel (N = 76) in Central Florida participated in an online survey that included demographic information, the Empathy Assessment Index, Professional Quality of Life Scale, and the Connor-Davidson Resilience Scale-10. Participants reported high perceptions of empathy (M = 4.11), resilience (M = 3.98), and quality of life (M = 3.28), but CF was perceived at low levels (M = 2.97). Empathy was not predictive of CF, indicating that overall empathy alone does …

Intelligent Deep Learning-Based Sign Language Translation System, Nada Rasem Shahin

Dissertations

The Deaf and Hard of Hearing (DHH) community uses sign language as a primary means of communication. However, the shortage of sign language interpreters and the existence of hundreds of sign languages limit accessibility and inclusion. Sign Language Machine Translation (SLMT) systems present a promising solution for bridging the communication gap between the DHH and the hearing individuals, supporting inclusive societies. In smart cities, such systems play an essential role in improving the quality of life on a community level. In particular, as the population’s well-being is critical, developing intelligent assistive technologies, such as SLMT systems, is necessary to provide …

Application Of The Tridiagonal Representation Approach And The J- Matrix Method Of Scattering In Theoretical Physics, Tunde Joseph Osunmusanmi

Dissertations

This dissertation is about the application of the Tridiagonal Representation Approach (TRA) in handling linear phenomenons, and for the first time, the J-matrix method of scattering in handling nonlinear phenomenons. The TRA is an algebraic method for solving linear ordinary differential equations of the second order. The advantage of the method in being algebraic is reinforced by the analytic power of orthogonal polynomials and special functions. On the computational side, it is favored as being reliant on powerful numerical techniques that deal with tridiagonal matrices such as Gauss quadrature and continued fraction. In the method, the solution of the differential …

Fully Decentralized Hierarchical Federated Learning At The Edge With Post-Quantum Secure Communication, Tariq Qayyum

Dissertations

Federated learning (FL) enables collaborative model training without centralizing raw data, but deploying FL at scale in real edge environments remains challenging because iterative training and aggregation must operate over heterogeneous, resource-constrained, and often mobile devices with time-varying connectivity. Conventional hierarchical federated learning (HFL) partially mitigates communication cost by introducing fog/edge aggregation, yet many designs retain cloud-based global aggregation and cloud-centric coordination. This places wide-area network latency on the critical path of every training round, creates a single point of failure, and limits responsiveness as model sizes and federation scale grow. Moreover, moving coordination and aggregation closer to the edge …

Design And Synthesis Of Coke-Resistant Nickel-Based Catalysts For Efficient Methane Reforming And Hydrogen Production, Abdulmuizz Adamson

Dissertations

Ni-based catalysts are widely employed in methane reforming and cracking processes, however, their industrial application remains constrained by rapid deactivation caused by carbon deposition (coking). This thesis investigates the role of iron on the catalytic performance and coking resistance of the catalysts with focus on the mode of incorporation, oxidation state, reaction environment, and concentration of iron present as dopant.

The results show that doping the γ-Al₂O₃ support of Ni catalysts with well-dispersed iron ions in the support matrix significantly enhances catalyst stability during methane partial oxidation (POM) and combined dry reforming and partial oxidation (DR-POM). At 700°C, catalysts containing …

Plasma N6 Polyunsaturated Fatty Acid Levels And Risk For Dementia: A Prospective Observational Study From The United Kingdom Biobank, Aleix Sala-Vila, Nathan Tintle, Jason Westra, Evan Dejong, Tom J. Clark, Paige Miller, Martha A. Belury, William S. Harris

Faculty Work Comprehensive List

Background

Some recent observational studies have linked higher blood linoleic acid (LA) concentration with lower risk of cardiometabolic diseases. However, these associations have not been observed for other n-6 polyunsaturated fatty acids (PUFAs), which, in some settings, have been linked to higher disease risk, and thus the controversy over the health effects of n-6 PUFAs remains. Dementia is a paradigmatic case of it.

Objectives

To investigate the association of LA and non-LA n-6 PUFAs with the risk of incident dementia.

Methods

We included 273,795 participants from the UK Biobank free of dementia at baseline for whom plasma n-6 PUFAs data …

Organizational Targets In General Equilibrium, Joel P. Flynn, George Nikolakoudis, Karthik Sastry

Cowles Foundation Discussion Papers

We build a general equilibrium model in which firms endogenously choose whether to target prices or quantities. We characterize how these choices of organizational targets depend on firms' uncertainty about microeconomic and macroeconomic factors. In equilibrium, the transmission of both nominal and real shocks hinges on firms' organizational targets. For example, under otherwise identical microfoundations, money is neutral under quantity targets and non-neutral under price targets. We further characterize how targets shape firms' strategic interactions and prove that the macroeconomic uncertainty that arises from each choice of targets reinforces incentives to choose that target. That is, choices of organizational targets …

From New Orleans To Orléans: How Perceived Connections Shape Destination Image, Hilmi A. Atadil, Helena F. Allman, Erol Pala, Qiulin Lu, Alison J. Green, Felicia N. Morgan

AMTP Proceedings 2026

Have you ever enjoyed a dish so much that it sparked an interest in experiencing the place where it was originally created? Culinary encounters may spark interest in distant destinations, but broader cultural, historical, and symbolic meanings often drive this interest through perceived connections. For example, exposure to French-influenced cuisine in New Orleans may draw individuals to France, driven not only by culinary authenticity but also by historical ties to Orléans. Grounded in social exchange theory, this study pursues two objectives: (1) to examine the underlying dimensions of perceived connections between destinations, and (2) to assess how these dimensions influence …

However, the study also notes limitations such as a convenience-based sample …

Running On Empty: How Burnout Derails Customer Delight And Sales Performance In Road Warrior Salespeople, Charshae L. Marshall-Phillips

AMTP Proceedings 2026

In an increasingly competitive marketplace, firms rely on customer delight for success. The physical and emotional toll on “Road Warrior” salespeople often acts as a barrier to this goal. This research proposes a model connecting antecedents (burnout) and outcomes (sales performance) via the salesperson's ability to create customer delight.

Employing a quantitative design with B2B salespeople traveling over 50% of the time, Structural Equation Modeling (SEM) is used to test hypothesized relationships. It is hypothesized that emotional exhaustion negatively impacts the capacity to create delight, subsequently lowering sales performance. Crucially, sales manager support is expected to moderate this relationship, acting …

Out Of Everything: Consumer Response To Extreme Scarcity, Melodie Philhours, Courtney Peters, John E. Mello

AMTP Proceedings 2026

Product shortages often evoke strong emotional reactions and subsequent behavioral responses that can amplify market disruptions. This research explores consumer behavior during two high-profile shortage events: the 2012 and 2020 U.S. ammunition shortage and the COVID-19 pandemic’s staple goods shortage. Using a comparative qualitative case study design, this research develops a psychologically grounded process model to explain how perceived scarcity can trigger emotional arousal, overreaction, and persistent marketplace behaviors. Drawing from reactance and self-determination theories, this research reveals how threats to autonomy, competence, and relatedness lead consumers to engage in coping tactics such as panic buying, hoarding, extended search, and …

Perceived Authority Of Ai-Generated Videos And Consumer Vulnerability, Kungpo Paul Tao

AMTP Proceedings 2026

The rapid integration of artificial intelligence (AI) into social media has transformed how consumers watch, interpret, and engage with video content. While AI-driven personalization enhances engagement, the growing realism of AI-generated videos blurs the boundary between authentic and fabricated content, increasing consumer vulnerability. This study examines how creativity influences consumer attention, interpretation, and interaction with AI-generated videos, and how it moderates the relationship between perceived authority and consumer engagement. Using secondary data collected from YouTube, the study analyzes publicly available AI-generated videos and user responses, including engagement metrics and comment-based sentiment indicators. The findings reveal that most consumers struggle to …

Cute, Collectible, And Contagious: Understanding The Starbucks Bear Cup Phenomenon, Natalya Vodopyanova

AMTP Proceedings 2026

This study examines the Starbucks Bear Cup phenomenon to understand how identity expression, scarcity perceptions, and fear of missing out (FOMO) shaped consumer engagement during a highly publicized limited-edition product drop. Using Consumer Culture Theory and scarcity/FOMO frameworks, the research investigates how consumers constructed meaning around the Bear Cup through social media displays, community rituals, and symbolic participation. A qualitative content analysis of Instagram posts revealed five dominant patterns: celebratory acquisition posts, expressions of scarcity frustration, curated identity displays, community interaction, and creative substitution using bear-shaped alternatives. Findings show that consumers used the cup as a vehicle for identity signaling …

Consumer Willingness To Pay In The Metaverse: A Case Of Digital Vs Phygital, Shivam Agarwal, Jaehoon Lee, Umair Usman

AMTP Proceedings 2026

This research examines how brand strategy influences consumer willingness to pay for digital fashion in the Metaverse, focusing on differences between digital-only and physical-first (phygital) brands. Grounded in the Theory of Consumption Values, the study investigates the role of emotional value in shaping consumer behavior. Across five experimental studies (N > 800), results consistently show that consumers exhibit higher willingness to pay for phygital brands compared to digital-only brands. This effect is driven by enhanced emotional value, as phygital offerings connect virtual consumption with consumers’ real-world self-concept, increasing perceived authenticity. Mediation analyses confirm emotional value as a key underlying mechanism. Furthermore, …

Digital Fashion For The Avatar Or Digital Fashion For The Self? Understanding Gen Z’S Willingness To Spend On Digital Fashion In The Metaverse, Shivam Agarwal

AMTP Proceedings 2026

This research examines Generation Z’s (Gen Z) willingness to spend on digital fashion in the metaverse, comparing preferences for avatar-based consumption versus physical consumption for the self. Drawing on generational cohort theory and identity-based consumption, the study proposes that Gen Z consumers—who are deeply embedded in digital environments—place greater value on avatar identity and self-expression in virtual spaces. Using a between-subjects experimental design, participants from Gen Z and older cohorts evaluate their willingness to purchase digital fashion for their avatars versus identical physical items for themselves. We predict that Gen Z will exhibit a significantly higher willingness to spend on …
