Additively manufactured (AM) metals offer the potential for customizable, cost-effective components, but qualification and certification are crucial. Key to this process is understanding pore dynamics under stress, typically analyzed using micro-computed tomography. This study introduces laboratory-scale “betatron” x-rays from laser wakefield acceleration as a high-throughput alternative for x-ray tomography of advanced materials, such as AM AlSi10Mg alloys. Coupled with 3D finite element modeling, this method provides detailed insights into stress-porosity interactions. The approach delivers high-resolution scans, revealing that pore shape and local triaxiality significantly influence fracture dynamics, supporting advanced material characterization. This work also demonstrates the potential and versatility of …

Mohammad Mirmazloumi, Harison Kipkulei, Rose Waswa, Tobias Landmann, Tom Dienya, Maximilian Schwarz, Fabrizio Ramoino, Clément Albergel, Gohar Ghazaryan

All Peer-Reviewed Publications

Drought presents significant challenges to agriculture, threatening food security and livelihoods, across many regions. In Kenya, recurrent droughts across diverse agro-ecological zones emphasize the urgent need for reliable and scalable drought assessment methods. Although drought assessment with various datasets has been carried out for this region, many of them often use course or moderate resolution data. This study uses high-resolution Sentinel-2 observations and machine learning to monitor intra-seasonal crop conditions and assess drought impacts across bimodal growing seasons. Using pixel-based supervised random forest models trained with multiple vegetation indices as input, we classify croplands into drought-affected and unaffected areas. The …

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 …

Digital Discipleship And Whole-Person Flourishing: A Mixed-Methods Study At Celebration Church, John W. Wyatt

Doctor of Ministry (DMin)

This study examines how digital participation influences whole-person flourishing within the context of Celebration Church, a contemporary American megachurch, addressing a critical gap in empirical research on digital discipleship and its theological implications. Using a convergent mixed-methods design, quantitative data from the Barna ChurchPulse survey compared in-person and online participants, while qualitative data from semi-structured interviews with leaders from eighteen American megachurches were analyzed thematically. Findings indicate that flourishing outcomes are largely comparable across digital and in-person cohorts, challenging assumptions that embodied participation is inherently superior for spiritual formation; however, statistically significant differences emerged in leadership involvement, serving, and engagement …

Collaborative Ministry Leadership: A Mixed-Methods Study Into The Application Of Collaborative Leadership In United Pentecostal Churches In The Southeastern United States., Omar A. Williams

Doctor of Ministry (DMin)

This dissertation examines how collaborative leadership, grounded in theological and practical applications, impacts ministry effectiveness in United Pentecostal Churches (UPCI) in the Southeastern United States. It employed a mixed-methods design, with in-depth qualitative interviews conducted with twelve senior UPCI pastors, and quantitative surveys administered to 63 members of their core leadership teams. Although collaborative leadership is a widely held ideal in ministry, a gap often exists between its theory and its practical implementation. The findings reveal a significant convergence in the relational, visionary, and developmental dimensions of collaboration. The pastors are theologically committed to rejecting autocratic models. They are perceived …

Branding Through Semiotics, Minimalism, & Branding Psychology: The Eurekafit Brand, Torri Salem

Theses

This paper examines how the combination of minimalism, semiotics, and branding psychology work seamlessly together to create an inclusive brand with an emotionally resonate visual identity system-- a brand that is cohesive and bridges the sub-brands of EurekaFit and Eureka CrossFit. What initially started as a logo redesign of Eureka CrossFit has now expanded into this dual-branding visual system, that communicates approachability, a sense of belonging and fitness, without being intimated, to its audience. This study investigates visual signifiers like color, typography and imagery, through a semiotic analysis and approach. I reduced clutter and visual noise and was able to …

Petals Of The Mind: A Digital Floral Interpretation Of Mental States, Corine D. Arrington

Theses

Petals of the Mind is an applied studio art project that explores the use of symbolic floral imagery to visually represent internal emotional states, specifically depression, anxiety, and ADHD. This project consists of six large format digital posters created in Procreate. Each emotional category is represented by a pair of flowers selected for their symbolic and structural characteristics: Blue Poppy and Black Rose for depression, Tulip and Aster for anxiety, and Honeysuckle and Wildflower Mix for ADHD. These flowers are intentionally deconstructed through layering, fragmentation, and motion cues to mirror common internal experiences such as emotional heaviness, vigilance, cognitive scattering, …

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 …

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 …

Evaluating The Role Of Social Media And Consumer Preferences In The Food Truck Industry, David Farabaugh, Kayla Weslager, Noah Kohan, Anthony George

As food trucks continue to grow in popularity and competition increases, offering good food alone is no longer enough to stand out. Instead, success often depends on delivering a memorable overall experience, including efficient service, convenience, brand personality, and consistent customer engagement. Using the featured food truck as a case example, this research analyzes customer preferences, travel patterns, and the influence of social media platforms such …

Consumer Adoption Of Cultivated Meat: A Multi-Value Perspective Using Empirical And Synthetic Data, Wei Fu

AMTP Proceedings 2026

The global demand for meat is projected to rise by more than 70% by 2050, creating pressure on natural resources and worsening environmental challenges. Cultivated meat, produced by growing animal cells in controlled environments, offers a sustainable alternative to conventional livestock farming; however, consumers acceptance remains uncertain. This study applies the Theory of Consumption Values (Sheth, Newman, & Gross, 1991) to examine how multidimensional consumption values influence consumer’s sustainable evaluation of cultivated meat. Using both empirical survey data from U.S. consumers and a synthetic dataset generated with the same instrument, the results show that functional value (food quality), social value …

Consumer Insights About Art Workshop And Art Boutique Preferences, Lucia M. Johnson, Richard Kaminski, Megan E. Marlin, Craig B. Joyner

AMTP Proceedings 2026

This research explores customer preferences, the effects of local demographics, purchasing habits, and the impact of social media platforms in driving customer engagement and loyalty. By surveying consumers, the study identifies the key qualities necessary to further engage potential and return customers, including pricing, location, and accessibility. The findings suggest a deep appreciation for creating artwork rather than buying artwork, distinct social media opportunities through the utilization of apps such as Instagram, Pinterest, and TikTok, as well as focusing their current offerings while broadening and segmenting their marketing initiatives. 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 …

Promoting Inclusive Tourism Via Metaverse, Shivam Agarwal

AMTP Proceedings 2026

This research explores how metaverse-based virtual tourism can be leveraged to promote inclusive tourism and enhance place branding. Drawing on emerging literature in virtual experiences and destination marketing, the study examines how immersive environments enable tourism marketers to project inclusive destination identities. In metaverse settings, users engage through customizable avatars, allowing for representation of diverse identities and accessible experiences for vulnerable populations, including older adults, individuals with disabilities, and LGBTQ communities. We propose that inclusive cues embedded within virtual environments—such as diverse avatars and accessible design—enhance perceptions of destination inclusivity, which in turn increase motivation to visit the physical destination. …

An Integrated Bayesian Network-Based Zero Trust Model To Quantify Cyber Risk In Small-Medium Businesses, Ahmed Abdelmagid

Engineering Management & Systems Engineering Theses & Dissertations

Small-medium businesses (SMBs) play a pivotal role in the worldwide economy as they constitute the most considerable portion of businesses in developed countries like the UK and the US. As such, SMBs are likely targets of cybercrimes by malicious agents because of their vulnerable IT systems. The digital infrastructure of SMBs is more likely to be hit by cyberattacks than large businesses due to many factors that facilitate hackers’ missions. These factors include a limited financial budget devoted to cybersecurity, a lack of knowledge, an underrating of how dangerous cyber threats are, and a shortage of IT expertise. The enormous …

The War Poetry Map Project: Exploring The Physical And Emotional Geography Of Conflict, Colin D. Halloran

English Theses & Dissertations

There can be no question that war is shaped by and has shaped cultures, and yet as an object of study it is rarely looked at from a cultural studies perspective. It is the great epics of war that form the cornerstones of Western literary tradition. It is the impact of war that gave rise to fields like trauma and memory studies. It is the propaganda produced, the hijacking of cultural industries, that help perpetuate wars. The War Poetry Map Project and accompanying written dissertation seek to move beyond historical and political contexts and view war as a cultural object. …

Shadowrunning The Human: Harebrained Schemes' Shadowrun Series And Transhumanism, Alexander P. Orelup

English Theses & Dissertations

I argue that Harebrained Schemes’ video game series Shadowrun critiques transhumanism in three distinct yet related ways: in terms of religion, political control, and identity capitalism. In doing so, Shadowrun attempts to counter claims that video games are an inherently transhumanist medium and provides an opportunity for players to resist a potential transhuman future. This further elucidates the trends and perceptions of transhumanism within American culture around the time period. I utilize a variety of methodologies in my argument, ranging from cultural studies, narratology, ludology, and close reading in order to grasp all of the audio-visual and gameplay elements that …

Women's Displacement And The Reclamation Of Identity: Navigating Landscapes Of Contestation In The Postcolonial Novel, Carol P. Harvest

English Theses & Dissertations

Landscapes affected by colonial domination are contested landscapes—places not only in danger of environmental destruction through colonial and neocolonial violence but also landscapes of struggle for people who survive in these precarious spaces. Historically, separate postcolonial and ecocritical literary analysis addressed contested landscapes; postcolonial critique centered on the lasting devastation of colonial violence on people and place, while ecocriticism, in its infancy, enjoyed the privilege of ignorance, focusing on endangered species and the preservation of land, but it did not consider the impact of landscapes on the very people who were largely forced to either leave or cross “natural” spaces. …
