Parental Distress, Coercive Control With Food, And Child Self-Regulation, Kattie Nguyen

UNF Graduate Theses and Dissertations

Self-regulation is the management of one's emotions, thoughts, and behaviors to adapt to a situation (Smith-Donald et al., 2007). During infancy and toddlerhood, parents foster self-regulation through co-regulation (e.g., sensitivity, responsiveness), helping children manage their emotions, behaviors, and thoughts (Butler & Randall, 2013). Parents who experience distress (e.g., depression, stress, anxiety) are more likely to use less responsive and harsher, controlling practices like coercive control. Coercive control with food is a practice where parents use food as threats or bribes to control their child’s emotions and behaviors (Vaughn et al., 2016). The present study examined the associations between parental distress, …

The Effect Of Coercive Control With Digital Devices On Emotion Regulation In Preschool-Age Children: An Experimental Approach, Gina Burroughs

UNF Graduate Theses and Dissertations

The experiment was an investigation on the differences in child emotion regulation between two groups during a disappointing gift task. Fifteen four-to-five-year-olds were randomly assigned to either receive coercive control with a digital tablet or an emotion-coping intervention. All children received a disappointing gift a second time as emotion regulation strategies (cognitive reframing, self-soothing, comfort-seeking) were recorded. A χ² test revealed a nonsignificant difference between frequency of post-manipulation emotion regulation strategies. Three cognitive-reframing subtypes were coded and an independent-samples t-test revealed between-group differences approaching significance, suggesting that adults can teach cognitive reframing to this age range. Additional analysis revealed …

Widowed And Wounded? Exploring The Health Impacts Of Adverse Childhood Experiences In Later Life Widowhood, Sierra Wickline

UNF Graduate Theses and Dissertations

Losing a spouse is considered one of the most stressful life events that disproportionately affect older individuals. Exposure to traumatic events at an early age can change the body’s response to subsequent stressors across the lifespan. These physical changes often impact people’s health. Utilizing data from the Health and Retirement Study, the current study aimed to investigate the link between: adverse childhood experiences (ACEs) and three indicators of health: inflammation (i.e., c-reactive protein [CRP], reflecting immune functioning), as well as self-reported depressive symptoms and physical health, among people who have lost a spouse. Participants included 97 widowed individuals aged 68 …

Energy-Efficient Security For Narrowband Iot Using Blockchain And Ep-Cumac, Hafizullah Kakar

UNF Graduate Theses and Dissertations

The Narrowband Internet of Things (NB-IoT) continues to expand but faces challenges such as cryptographic overhead and energy consumption. Security frameworks such as blockchain and Energy-Performance Cumulative Message Authentication Codes (EP-CuMAC) rely heavily on SHA-256, which is not optimized for energy-limited devices.

This work unifies two complementary approaches, a hybrid blockchain-based NB-IoT framework and an EP-CuMAC-based framework, by engineering their cryptographic core with an Energy Complexity Model-optimized SHA-256 (ECM-SHA256). ECM applies parallel memory-bank mapping and block-level access optimization to reduce redundant power usage while preserving algorithmic integrity.

Experimental evaluation on identical Intel DDR3 systems using pyRAPL shows energy savings of …

Brewing Black Girl Magic: From Hush-Toned Kitchens To Educational Spaces: A Narrative Inquiry Into The Inherited Wisdom, Radical Resilience, And Professional Becoming Of Black Women, A Three-Paper Dissertation, Sheryl Patterson-Coulibaly

UNF Graduate Theses and Dissertations

This dissertation examines how racialized and gendered expectations shape the professional experiences of Black women in predominantly white educational spaces. Drawing on a three-article format, this study investigates how Black women navigate institutional conditions that depend on their labor yet fail to provide adequate support. Grounded in Black Feminist Marxist Thought and emerging Black Womanist Theory, the study centers the emotional, relational, and spiritual dimensions of Black women’s labor, extending traditional analyses of work, leadership, and resilience.

Of Fire and Fabrication: A Systematic Review on the Myth of Strength and Erasure of Black Women in White Educational Spaces reveals that …

Integrating Inquiry, Peer Observation, And Professional Learning Communities: Teachers’ Experiences With A Job-Embedded Professional Learning Design, Tiffany Outman

UNF Graduate Theses and Dissertations

Professional learning is often experienced through disconnected initiatives that limit opportunities for sustained collaboration, reflection, and instructional growth. This qualitative action research study explored teachers’ experiences with the integration of teacher inquiry, peer observation, and professional learning communities (PLCs) as a design for job-embedded professional learning within an elementary school setting. The study emerged from an existing culture of collaboration and peer observation at Timber Oaks Elementary, a suburban elementary school in Northeast Florida, and examined what happened when inquiry was intentionally integrated into those structures as the next stage of the school’s professional learning journey. While the professional learning …

Exploring The Lived Experiences Of Families Of Students With Significant Disabilities In Accessing Community Transition Supports In Rural Settings, Michael David Green Jr.

UNF Graduate Theses and Dissertations

The transition process beyond high school can be daunting for students with disabilities and their families. Families often encounter difficulties accessing community-based supports after students leave the K–12 education system despite federal legislative mandates under the Individuals with Disabilities Education Act (IDEA) and the Workforce Innovation and Opportunity Act (WIOA). Rural contexts further complicate the experience for families accessing adult services after high school. The current hermeneutic phenomenological study explored how families of students with significant disabilities experienced accessing community transition supports after leaving high school in rural contexts. Through the lens of van Manen’s hermeneutic phenomenology, the study explored …

Development And Testing Of A Low-Cost Inertial Impact Sensor, Gabriel Michael Pesek

UNF Graduate Theses and Dissertations

Acceleration sensors have seen increasing usage within sports to detect when somebody receives an impact to their head which can potentially lead to Traumatic Brain Injury (TBI). While adoption of these sensors has steadily risen, the cost of these sensors is often cited as a reason they have not been as widely adopted, especially for amateur teams. This leads to the need for a lower-cost option for detecting these impacts. To fill this gap, a low-cost, lightweight acceleration sensor was designed that exploits the inertia of a working fluid on impact in order to rupture a metallic membrane which acts …

Thermomechanical Modeling Of Transpiration Surfaces For Hypersonic Propulsion, Spencer D. Smith

Graduate Studies Theses and Dissertations 2026

Hypersonic flight vehicles are a promising form of high speed passenger transport and efficient space access architectures. However, they are fundamentally a thermally limited technology. High heat fluxes exceeding 10 MW/m2 and gas temperatures between 3000-4000K can be found both within the engine, and on the outer surface. Current conventional engineering materials are non-viable at these conditions. In order to make these materials viable, active cooling strategies could be utilized. One particularly promising type is transpiration cooling, where a coolant is diffused through a porous surface. Although researched heavily in the 1960s, adoption is still minimal. Part of the reason …

A Sensor Fusion And Optimization Framework For High-Resolution Power Outage Detection And Energy Asset Allocation, Elizabeth Trader

Graduate Studies Theses and Dissertations 2026

Existing power outage datasets lack the spatial and temporal resolution required for neighborhood- level risk assessment, and conventional energy system design optimizes for cost without accounting for community-level demand - resulting in inefficient and inequitable asset de- ployment. This dissertation presents IONCORTEX, a framework integrating three technical contributions: a heterogeneous sensor fusion pipeline combining social media signals with municipal infrastructure records for intersection-level outage detection at six-hour tempo- ral resolution, maintaining detection capability during telecommunications disruptions; a techno-economic analysis pipeline evaluating photovoltaic, battery storage, hydrogen, and diesel portfolios using NREL’s System Advisor Model with Monte Carlo uncertainty quan- tification; and …

Site Use And Demographic Changes In A Northwest Atlantic Sea Turtle Foraging Ground, Ryan C. Welsh

Graduate Studies Theses and Dissertations 2026

and site fidelity, making mortality difficult to distinguish from redistribution. We developed a behaviorally explicit framework to separate true mortality from changes in availability caused by movement and redistribution. We evaluated this problem for juvenile green turtles (Chelonia mydas) and loggerhead turtles (Caretta caretta) captured at the St. Lucie Nuclear Power Plant intake canal on Florida’s Atlantic coast using a multi-decade capture–mark–recapture record spanning 1977 - 2023. Hidden Markov Models classified individuals into latent habitat-use strategies (Nomadic, Resident, and Transient) based on capture timing and body size. Across both species, these strategies captured consistent differences in site fidelity and recapture …

Oblique Detonation Waves In Internal Axisymmetric Converging Flow, Zachary P. White

Graduate Studies Theses and Dissertations 2026

Detonative combustion offers significant thermodynamic advantages for high‑speed propulsion, motivating the development of detonation‑based combustors for hypersonic flight. Among these, oblique detonation wave (ODW) engines require extremely high combustor velocities to achieve steady wave stabilization. While most prior experimental and numerical studies have focused on planar two‑dimensional geometries, axisymmetric combustors offer practical benefits for hypersonic vehicle integration and may influence achievable pressure gain. However, the effects of inward‑turning axisymmetric compression on ODW formation and performance remain largely unexplored. This work presents an experimentally stabilized ODW formed on an internal axisymmetric converging ramp. Experiments were conducted in a high‑enthalpy blowdown wind …

Infrared Systems And Their Application On Target Detection And Geolocation, Li Zhang

Graduate Studies Theses and Dissertations 2026

The infrared spectrum contains various sub-bands (from near infrared (NIR) to long-wave infrared (LWIR), which are specialized at different detection tasks. Objects that are well camouflaged to human vision can be highly noticeable in NIR imagery. For vision navigation, the varying illumination condition and the cluttered urban background poses challenges in the visible band but can easily be resolved by using a thermal imager operating in LWIR. Despite this potential, practical deployment remains limited by the lack of suitable platforms, task-specific datasets, and long-duration field validation. This dissertation addresses these gaps through the design and evaluation of two infrared sensing …

From Motherhood To Sisterhood: Women Strike For Peace And The Transmission Of Feminist Consciousness, Olivia R. Aldrich

Graduate Studies Theses and Dissertations 2026

Women Strike for Peace (WSP) has traditionally been understood as a maternalist peace movement that emerged in response to atmospheric nuclear testing during the early Cold War era. This thesis argues that WSP’s history reveals a more nuanced relationship between motherhood, feminism, and political activism than existing scholarship has suggested. Rather than operating in distinct stages, maternalism and feminism operated simultaneously, working alongside one another throughout the organization’s history. Furthermore, this thesis builds upon Ednie Kaeh Garrison’s concept of feminist “radio waves,” arguing that WSP functioned as a transmitter of feminist consciousness, where ideas, organizational practices, and different political identities …

Effects Of Back-Pressure On Pseudo-Shock Systems, Emil C. Alunno

Graduate Studies Theses and Dissertations 2026

The isolator of a scramjet engine houses a pseudo-shock, a compressive flow structure that raises the static pressure and decelerates the incoming supersonic flow for efficient combustion while shielding the inlet from the elevated pressure downstream. Under sufficient back pressure the leading shock bifurcates and forms a shock train followed by a shockless mixing region, and the resulting system oscillates even under nominally steady conditions; this unsteadiness distorts the flow, can drive the pseudo-shock out of the isolator and unstart the inlet. This thesis experimentally examines how a pseudo-shock in a constant-area isolator at a measured entrance Mach number of …

An Examination Of The Impact Of School Context And Socioeconomic Status On Agency And Creative Productivity In Gifted High School Students, Elizabeth Bronson

Graduate Studies Theses and Dissertations 2026

This explanatory sequential mixed methods study investigated gifted high school students’ perception of the agency afforded them within school settings, and the relationship between these perceptions and their creative productivity. A sample of 140 students was drawn from a population of 966 identified gifted high school students. These students were contacted via their parents and asked to complete the Agentic Engagement Scale (AES) questionnaire which provided gifted high school students’ perceptions of the agency afforded at school. No significant differences in perceived agency were found across demographic variables, including socioeconomic status and school type. Of the respondents, 10 students were …

A Systematic Review And Characterization Of Privacy Noncompliance In Real-World Applications, Alexander E. Charkiewicz

Graduate Studies Theses and Dissertations 2026

Software applications increasingly rely on user data to provide their functionality, but improper handling of such data can lead to serious privacy noncompliance with applicable regulations and policies. A prominent example is the Facebook–Cambridge Analytica scandal, in which a third-party application collected the personal data of approximately 87 million Facebook users without users' consent. Despite growing attention to privacy compliance, two key challenges hinder the systematic understanding and analysis of privacy noncompliance. First, unlike security vulnerabilities, which have been systematically categorized through taxonomies such as the Common Weakness Enumeration (CWE), privacy noncompliance lacks a technical taxonomy describing how it manifests …

Non-Gaussian Phenomena In Light Scattering And Applications, Shubham Atul Dawda

Graduate Studies Theses and Dissertations 2026

Physical reality is rarely deterministic; which, when probed by electromagnetic fields that also fluctuate, leads to observables that are most efficiently modelled as statistical processes. At equilibrium, this is usually achieved by invoking the Gaussian statistics of underlying physical processes, however, in practice, one often encounters out-of-equilibrium conditions where Gaussian descriptions may not suffice. Such situations are plentiful in nature– from biology to astronomy. This dissertation addresses several non-Gaussian phenomena associated with light scattering, and includes specific models’ derivations, experimental techniques developments, and demonstrations of potential applications. The systematic presentation will consider circumstances that infringe upon specific assumptions of the …

Evaluating Novel Targeted Combination Therapies For Gastrointestinal Cancers, Joseph A. Goode

Graduate Studies Theses and Dissertations 2026

Gastrointestinal (GI) cancers remain among the leading causes of cancer-related mortality worldwide, with therapeutic resistance continuing to limit the effectiveness of current treatments. Three complementary studies were conducted to identify therapeutic vulnerabilities and evaluate novel combination strategies in pancreatic ductal adenocarcinoma (PDAC) and colorectal cancer (CRC).  First, dual inhibition of fibroblast growth factor receptor 4 (FGFR4) and phosphoinositide 3-kinase (PI3K)/mammalian target of rapamycin (mTOR) signaling was investigated in PDAC models. A combination of targeted drug treatments reduced viability, clonogenic survival, migration, and suppressed signaling pathways involved in translational control. This supported a functional interaction between FGFR4 and PI3K-mTOR co-activation in …

Policy Into Practice: Exploring School Counselors' And School Psychologists' Knowledge And Sensemaking Towards The Application Of Alternative Gifted Identification Criteria For Lower Socioeconomic Students, Brittany E. Hague

Graduate Studies Theses and Dissertations 2026

Persistent underrepresentation of students from lower socioeconomic status (SES) backgrounds in Gifted education reflects long-standing structural inequities embedded in identification policies and practices. In response, many Florida school districts have adopted equity-oriented identification reforms, including universal screening, local norms, and multiple-measure approaches. However, policy equity does not automatically translate into equitable outcomes; rather, it is mediated through the interpretive work of school-based practitioners. Guided by Sensemaking Theory, this convergent mixed-methods study examines how school counselors and school psychologists construct meaning around alternative Gifted identification criteria and how their beliefs, professional judgment, and organizational contexts shape implementation. The study explores how …

The Odyssey Of Emotion Regulation In Extremis: How Challenges Lead To Team States Through Regulation And Psychological Safety In Ice, Andres Kaosaar

Graduate Studies Theses and Dissertations 2026

Isolated, confined, and extreme (ICE) teams experience challenges that require continuous emotional adaptation. Although emotion regulation (ER) has been recognized as critical for functioning in these contexts, little is known about how specific challenges shape regulatory responses, how team climate influences those responses, and how individual regulation accumulates into team-level outcomes. This dissertation develops and tests a multilevel framework linking challenge exposure, perceived psychological safety, individual ER, team emotions, and team viability in space analog environments. Data were collected from 36 crews (N = 184) participating in two-week missions at two space analog stations, yielding 2,577 daily observations and …

Sustaining High-Quality Service-Learning In Research Intensive Universities: A Qualitative Study Of Instructor Perspectives, Marika Koch

Graduate Studies Theses and Dissertations 2026

In a world that often feels disconnected due to our sociopolitical climate, there is a need to create socially aware and civically engaged adults. Service-learning integrated into higher education courses can do that and more. Research indicates that both students and the community benefit significantly when students participate in effective service-learning classes. Students who take service-learning courses in college tend to exhibit higher academic achievement, enhanced social and emotional skills, and greater long-term civic engagement. Effective service-learning courses share three common elements: they foster a strong connection to course objectives, promote reciprocity for all involved, and encourage active student reflection. …

The purpose of this interpretative phenomenological analysis was to explore the perceptions and experiences of high school English Language Arts teachers in one public school district in the state of Florida as they navigated educational legislation that has been implemented over the last five years. The study interviewed ten experienced high school ELA teachers who had taught for more than five years in Florida’s public school system. One semi-structured interview was conducted along with brief follow-ups to share thematic statements with the participants. This study also included a document analysis of HB 1467 and HB 1069 as well as the …

Hunter. Hunted. Human: Warfighters' Emotional Responses To Weapons In Tactical & Strategic Context, Simon Mace

Graduate Studies Theses and Dissertations 2026

Human emotional responses to weapons have long been assumed to be relatively parsimonious, comprised predominately of aggression, anxiety, and fear responses. However, most research on this weapons effect has focused on civilians – who are notably more likely to be targeted by than to employ weapons. So, there is reason to speculate that emotional responses to weapons vary more than previously believed. This is significant for three reasons. First, positive emotional responses generate more desirable combat behaviors, specifically the willingness to engage adversaries. Second, negative emotional responses catalyze an unpredictable range of behaviors, many of which are tactically and operationally …

Generating Boundary Conditions For Compound Flood Modeling In A Probabilistic Framework, Pravin Maduwantha Mahanthe Gamage

Graduate Studies Theses and Dissertations 2026

Flooding in coastal riverine environments is often driven by the combined influence of multiple hydrometeorological flood drivers, including storm surge, rainfall, waves, and river discharge, which is referred to as compound flooding. A robust flood hazard assessment requires simulation of a wide range of flood driver conditions through dynamic compound flood models to capture the variability in resultant flooding. However, such assessments remain limited by the short length of observational records and the high computational cost of physics-based methods used to generate temporally varying boundary conditions. This dissertation develops a statistical framework to characterize compound flood drivers and generate large …

Communication College Students And Their Career Readiness: An Evaluation From The Employer's Perspective, Carson Mann

Graduate Studies Theses and Dissertations 2026

Higher education institutions are seen as places that educate students in specific subjects and provide training that leads to either a career or further learning opportunities. Unfortunately, public trust in higher education has plummeted since 2015. The evolution of higher education has been the subject of speculation by various groups, but developing translational skills through effective internships could very well solve the issue at hand. Institutions ought to have data -driven evidence about their disciplines’ effectiveness and their translational ability to the workforce. To understand this, student career readiness must be evaluated. Students' career readiness is a vital measure of …

“I Am A Refugee Direct From Mississippi:” Drafting And Substitution As Muster Methods In Shaping Black Participation In The Union Army, 1863–1865, Carson R. Maschmeier

Graduate Studies Theses and Dissertations 2026

Historians have frequently emphasized voluntary enlistment as the primary means through which Black men entered military service, portraying military participation as an expression of autonomy and a pathway toward freedom and citizenship. Within this scholarship, few historians have examined how Black participation in the Union army as draftees and substitutes impacted Black men and their families. This thesis examines the role of drafting and substitution in shaping Black military participation in the Union Army during the American Civil War. By focusing on Pennsylvania's 8th United States Colored Troops (USCT), this study argues that drafting and substitution complicate the commonly accepted …

Experimental Demonstration Of A Laboratory Scale Packed Bed Reactor For Thermochemical Energy Storage Using Embedded Heating Elements, Zachary Monem

Graduate Studies Theses and Dissertations 2026

Thermochemical energy storage (TCES) is an emerging technology that is being studied as a carbon-neutral renewable alternative to conventional methods of large-scale power generation, such as the utilization of fossil fuels. TCES makes use of thermochemical materials to store and discharge energy in two-step reversible chemical reactions. Among the most promising TCES materials are metal oxides, which possess significantly higher energy storage densities compared to other TCES materials; consequently, thermochemical reactors are used to store and discharge large amounts of energy during reduction-oxidation cycles using metal oxide materials. The current work focuses on the design and experimental demonstration of a …

Comics In The Classroom: Social Science Teachers' Lived Experiences With Comic Art In Instruction, Robert W. Mcintosh

Graduate Studies Theses and Dissertations 2026

This qualitative descriptive phenomenological study explored secondary social science teachers’ lived experiences with comic art in classroom instruction. Existing research suggests that comic art, including comic books and graphic novels, can support student engagement, content understanding, visual literacy, and critical thinking; however, less is known about how teachers experience and make decisions about using comic art in social science education. Framed by Technological Pedagogical Content Knowledge and Social Cognitive Theory, the study treated comic art as a representational instructional technology and examined how teacher confidence and the context of their experience shaped its use. Data were collected through semi-structured interviews …
