Individualized Models For Perception And Cognition, Dominic Marticorena

McKelvey School of Engineering Graduate Student Theses & Dissertations

This dissertation develops individualized models of perceptual and cognitive behavior, inferring latent capacities from limited data with sufficient efficiency, precision, and generality for person-level prediction. In perception, a nonparametric Bayesian framework for adaptive psychophysics is extended from audition to vision, producing an estimator that recovers dense individualized contrast sensitivity profiles through variational inference, a generalized kernel, and information-guided stimulus selection. A multitask extension enables simultaneous estimation of multiple psychometric fields by exploiting shared latent structure. Transferring this inferential logic to cognition, where relevant dimensions must be supplied by task design rather than physics, requires new measurement infrastructure. A Minecraft-based platform …

Inference-Time Scaling For Robust And Adaptive Computational Imaging, Yuyang Hu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Computational imaging has transformed fields such as medical imaging, computational photography, and remote sensing by combining physical measurement models with advanced image reconstruction algorithms. Two major paradigms have driven significant progress: model-based deep learning (MBDL), which integrates learned priors with physics-based data consistency, and generative models, especially diffusion models, which capture complex image distributions and enable posterior sampling for uncertainty quantification. Despite their success, most existing methods still operate under static inference: they rely on fixed pretrained priors, predetermined sampling procedures, and a fixed forward model during reconstruction. This rigidity limits their robustness in the presence of distribution shift, complex …

Functional And Spatially Specialized Inhibition And Neuromodulation During Learning In The Hippocampus, Gerardo Enrique Molina

McKelvey School of Engineering Graduate Student Theses & Dissertations

The hippocampus relies on a diverse network of regulatory components for memory formation. Neuromodulators and inhibitory interneurons act in concert with excitatory neurons to control learning. Even within one of these components there is a vast diversity of genetic or chemical composition that may come from unique sources at uniquely timed intervals or events. The goal of this dissertation is to identify specific functional-behavioral attributes of two such examples: parvalbumin (PV)-expressing interneurons and the neuromodulator dopamine, in hippocampal CA1. In separate experiments, I used two-photon microscopy of the calcium sensor, GCaMP, which measures neuronal activity, and GRAB-DA, which reports levels …

An Autism-Centered Analysis Of The Aesthetics And Narrative Of Gene Wolfe’S Book Of The New Sun, Sebastian Peterson

Electronic Theses and Dissertations 2020 - Present

Much of the recent work published within the literary neurodiversity studies field focuses on how certain writing techniques can be viewed as representing the experience of being autistic by influencing the reader so that they experience distinctly autistic patterns of cognition. Likewise, the Book of the New Sun series employs many such techniques within the narrative and prose. This is in addition to the fact that the plot contains elements that mirror the relationship and conflict between those with autism and neuronormative hegemony (that being the ways in which societies oppress, mistreat, and belittle those not deemed “neurotypical”). The goal …

Soft Systems For Community-Based Hcv Management In Indonesian Oil Palm Plantations, Neny Indriyana, Suyud Warno Utomo, Tri Edhi Budhi Soesilo, Linda Darmajanti

Journal of Environmental Science and Sustainable Development

Certification mandates under the Roundtable on Sustainable Palm Oil (RSPO) and Indonesian Sustainable Palm Oil (ISPO) have made measurable strides in promoting sustainability standards, yet governance challenges in High Conservation Value (HCV) 4, 5, and 6 management remain insufficiently addressed within Indonesian plantation contexts.  Drawing on adaptive governance theory and the social-ecological systems framework, this study argues that such gaps are structurally linked to the marginalisation of community agency within corporate-dominated decision-making. This study proposes and empirically evaluates an integrated governance framework that positions community engagement as a functional contributor to conservation outcomes within plantation landscapes of West Kalimantan, under …

Uuvs Using Sound Detection, Daniel Ginsburg, Ethan Carpio, Preston Jacob, Casey Cooper

Mechanical Engineering Capstone Design Projects

The contents of this report contain the details of the 2025-2026 school year regarding team 14’s capstone project about building an Unmanned Underwater Vehicle (UUV) using sound detection. At the beginning of this project it was decided that the project goals would be updated. In previous years the students had to use sound to follow a path and drop a payload along that path in the pool. Now this has been changed so that the team now knows the path and drop location beforehand. This removes the need for sonar and sound detection. This makes the project easier and more …

The sample is composed of 231 community college and university students enrolled in STEM programs. Data …

Biblical Leadership And Gender: Balancing Cultural Context And Theological Conviction, Lorie Lynn Heath

Doctoral Dissertations and Projects

God originally made male and female in His image, imparting to them a shared authority over creation. They were co-heirs equal in purpose, mission, and value. However, cultural practices and patriarchal traditions have long obscured this original biblical design. Consider a qualified young woman in a local church, called, talented, and valued by her congregation, yet repeatedly overlooked for preaching and teaching positions because of her gender. Her story is not unique. This misapplication of Scripture not only harms women but also weakens the body of Christ and impedes the church’s testimony to the gospel. Accurate comprehension of the Bible …

No Place To Stand: Gender, Discipline, And The Contradictions Of Military Womanhood, 1945–1975, Angela Bouma

Doctoral Dissertations and Projects

From 1945 to 1975, American servicewomen stood inside an institution that depended on their labor while restricting their place within it. The post World War II military relied on women to sustain administrative, technical, and medical operations across a widening Cold War landscape, yet guarded the authority and recognition attached to combat and command. Women kept global communications running, delivered medical care in field hospitals, and carried out intelligence work that shaped military decisions. However, legal and cultural boundaries limited the reach of such contributions.

The 1948 Women’s Armed Services Integration Act formalized this tension. Regular status came with ceilings …

Exploring How Leadership And Religion Improve Work Motivation And Well-Being, Laura G. Strickland

Doctoral Dissertations and Projects

Leadership is a well-researched topic that shows that leaders have a significant impact on employees’ perspectives of work motivation and well-being factors. There are gaps in research on older generations and the impacts of leadership since there has been such a heavy focus on research learning about the incoming work force. Other studies have found that strong religious beliefs help build better leadership skills. Therefore, the purpose of this study was to examine how leadership behavior and religious beliefs impact employee work motivation and well-being in older adults. In this qualitative study, interviews were conducted to understand older adults’ experiences …

A Phenomenological Study On Pastoral Leadership In Post-Covid In-Person Worship Attendance Growth Within Southern Baptist Congregational Polity, David Christian Justice

Doctoral Dissertations and Projects

The purpose of this qualitative phenomenological research is to examine and reveal the perceived experiences of pastoral leadership in post-COVID in-person worship attendance growth among North Carolina Southern Baptist Churches (NCSBCs) operating within the framework of congregational polity. The theory guiding this study is that pastoral leadership is vital for post-COVID in-person worship growth in Southern Baptist Churches (Bryan, 2024; Hudson, 2018). Hudson’s (2018) competency model for church revitalization identifies pastoral leadership as “one of the most consistent predictors of a church’s ability to grow after a period of plateau or decline” (p. 3). The unique leadership structure of Southern …

Psychological Contract And Perma Well-Being, Ryan T. Roddey

Doctoral Dissertations and Projects

The PERMA model, a five-factor framework- positive emotion (P), engagement (E), relationship (R), meaning and purpose (M), and accomplishment (A)- was developed to assess the building blocks of well-being (Seligman & Csikszentmihalyi, 2000). In the workplace setting, organizations perceive how positive organizational psychology shapes employee well-being through exchange relationships (Donaldson et al., 2022). Previous research confirms the effect of the psychological contract on well-being when the contract is violated in the workplace. Yet, limited studies examine the association between overall well-being and employee exchange agreements, such as the psychological contract. This study explored the differences between relational and transactional psychological …

Exploring The Lived Experiences Within The First Two Years After Gray Divorce Among Middle-Aged Adults, April R. Hill

The purpose of this research was to explore the lived experiences within the first two years after gray divorce among middle-aged adults. Historically, the research has focused on young adults who have experienced divorce, with limited data on middle-aged adults divorcing after being married for at least a couple of decades. Utilizing the suggestion by Polkinghorne, phenomenological researchers conduct interviews with 5 to 25 participants who have gone through the same phenomenon. Thus, this researcher interviewed 14 participants, reaching saturation. These participants were operationally defined as middle-aged adults who have had recently divorced after 20+ years of marriage. This study …

Early Educational Benefits In Criminal Justice Learning And Practice: Efficacy Of High School-Level Criminal Justice Programs, Richard Brewer

Doctoral Dissertations and Projects

The value of educational progress and placing optimally educated agents into the criminal justice career field has been carefully examined throughout the history of justice, and the procurement of skills and knowledge applicable to field operations is aligned with several core Peelian tenets. The safe assumption is that every police action is observed or documented, and efforts must be made to build bridges to amend the law enforcement misconducts of yesteryear. One methodology to reduce the number of undesired incidents, expand occupational growth, and obtain optimal confidence levels among personnel in the volatile policing arena is implementing earlier learning development …

Doctoral Dissertations and Projects

This qualitative phenomenological study sought to understand the impacts of adverse childhood experiences (ACEs) and what mitigating factors can help alleviate the pain and suffering caused by their residual life-long impacts. A literature review was done, and a gap was found on the subjects of personal spiritual disciplines (PSDs) of prayer, Bible reading/study, public/private worship, repentance and forgiveness as mitigating factors for the impacts of ACEs. This study recruited 15 participants who identified as victims of ACEs and used PSDs as mitigating factors to overcome the lifelong impacts. Interviews were done, using an online forum, to question participants on their …

Turning The Ear Into An Eye: Using Descriptive Language To Connect With The Creative Imago Dei In Preaching, Jonathan Phillip Hamm

Doctoral Dissertations and Projects

What factors influence an audience's imagination, enabling them to visualize a preacher’s words? The claim being addressed is that when descriptive language is used in preaching—such as stories, analogies, and metaphors—it connects with the representational commission to have dominion over creation that is given through the imago Dei of the sermon recipient, drawing images in their minds and allowing listeners to see what the preacher says. The research begins with an exegetical study of the concept of the imago Dei found in scripture, establishing a theological foundation through passages such as Genesis 1:26-27, 5:1-3, and 9:6, Psalm 8:4-6, Romans 8:29, …

An Applied Study In Community College Classical Guitar Education, Jaime Adrián Garcia

Doctoral Dissertations and Projects

Despite the expansion and popularity of classical guitar programs in universities and conservatories worldwide, a lack of attention exists for students considering a music education career deficient in music literacy and guitar technique. In the modern sense, classical guitar pedagogy begins with Andres Segovia and the iconic master classes he conducted throughout the world from the 1950s up until he died in 1987. Guitar education in academia is still a relatively new concept. At the same time, there are various method books from 19th-century guitar masters and modern guitar educators. Despite these developments in guitar education, students in an open-enrollment …

Using a randomized, counterbalanced within-subjects crossover design (N = 13), each participant completed two warm-up conditions in a single indoor session: (a) a standard dynamic baseball warm-up and (b) the same standard warm-up followed by a brief Olympic-lifting PAP sequence (1 x 3 clean pulls at 80% predicted one-repetition maximum [1RM], 1 x 3 power cleans at 80% predicted 1RM, and 1 x 3 power jerks at 60% predicted 1RM, with 2-minute rests between sets) and a 3-minute …

Developing Biblically Based Media As A Tool To Influence Societal Values Towards Godliness, Jasmine Deanne Andrews

Doctoral Dissertations and Projects

The media can influence cultural values using narrative storytelling. Common tropes in narrative storytelling may reinforce cultural norms that vilify women and reinforce racial stereotypes. Frequent exposure to these negative tropes in the media condition audiences to accept gender and racial biases rather than society taking responsibility for gender and racially motivated violence and social mistreatment. These gender and racial biases can be further reinforced by church doctrines that support cultural norms that vilify women and reinforce racial stereotypes. This study exposed audiences to biblically-based media using the faith-based film, Then Sings My Soul, to determine the types of images …
