A Charcoal Analysis At The Jupiter Inlet 2 (8pb35) Site In Jupiter, Florida, Christopher Rubido

Electronic Theses and Dissertations

This project utilizes five sediment core samples from the Jupiter Inlet Lighthouse archaeological (8PB35) site in northern Palm Beach County, Florida (four core samples derived from areas where cultural material has been found and one core from a nonanthropogenic area). These sediment core samples were analyzed using a variation of a tested charcoal analysis methodology often used with lake and peat bog cores, but in this case, the cores come from an upland coastal environment. The findings of this project have shown efficacy of the modified methodology for locating charcoal peaks in habitation zones found in core strata and as …

A Danish Romantic Organ Voice: The Music Of J.P.E. Hartmann And The Marcussen & Søn Organ, Benjamin T. Tischner

Undergraduate Honors Theses

This thesis examines the organ works of J.P.E Hartmann (1805-1900), an organist and composer who was at the center of the Romantic movement in Denmark. Hartmann, along with contemporaries Niels W. Gade and A.P. Berggreen, helped establish a musical style unique to Denmark during the Romantic era. This thesis analyzes this Danish musical style as it pertains to Hartmann’s compositions, defining what it means for this music to be uniquely Danish. In this regard, Hartmann’s organ works can be distinguished from other corners of the Romantic organ repertoire, especially the organ music being composed in Germany around the same time. …

The Effects Of Anti-Gdnf On The Sensory And Autonomic Nervous System In The Heart, Tryphosa Konadu

Honors Theses

Heart disease is the number one leading cause of death; about 1 in every five deaths is due to heart disease. “Heart disease” is a catch-all phrase that encompasses a variety of conditions that affect the heart’s structure and function. Many of these symptoms can be attributed to dysfunction within the parasympathetic, sympathetic, and sensory nervous systems. Neurotrophic factors like GDNF (Glial cell line-derived neurotrophic factor), BDNF (Brain-derived neurotrophic factor), and NGF (Nerve growth factor) promotes neuronal survival, and regeneration of the nerve fibers of the heart, especially sensory and autonomic nerve fibers. Studies have suggested that increased expression of …

Intra-Individual Cognitive Variability As A Predictor Of Mild Cognitive Impairment In Older Adults: Longitudinal Patterns, Clinical Classification, And Sex Differences, Joshua Conniff

Electronic Theses and Dissertations

Some older adults score differently on the same cognitive test from one visit to the next, and that inconsistency has been proposed as an early warning sign of decline. This dissertation tested whether within-person variability actually tells us anything useful about who has, or will develop, mild cognitive impairment (MCI). A total of 334 older adults completed quarterly neuropsychological testing over three years as part of a larger longitudinal study. Visit-to-visit variability was measured as the mean absolute successive difference on the MoCA, the MMSE, and a battery of memory, executive, language, and visuospatial tasks, and MCI was classified from …

Slowing Down With The Archives: Reexamining An Archaeological Context From Pre-Columbian Coastal Ecuador, Madison Rieth

Electronic Theses and Dissertations

Archaeological excavations leave behind extensive paper trails and repositories of materials. When these materials are transformed into an archive it disjoints the archaeological process and increases the possibility for knowledge loss. The archive from Salango Site 141C showcases this. These materials have remained in storage or on display since their original excavation and over time the understanding and significance of the site has been lost. Utilizing the theoretical framework of slow archaeology, this thesis analyzes the various parts of the archive from 141C. Using both mortuary archaeology and skeletal analysis, these parts of the archive are reconciled, compared, and integrated. …

Results indicated that much of the eastern shoreline remained relatively stable, while greater variability was observed along the southern shoreline adjacent to the …

Legislative Signals And Human Rights Advocacy: A Longitudinal Analysis Of U.S. Congressional Resolutions And Ngo Reporting In The Post-Cold War Era, 1989-2004, William J. Manosh

Electronic Theses and Dissertations

This thesis examines the unique relationship between nongovernmental human rights reporting, and U.S. congressional attention during the post-Cold War period, 1989-2004. Using a longitudinal content analysis research method, it compares human rights-related resolutions from the 101st through 108th Congresses with materials from Amnesty International, Human Rights Watch, and Human Rights First. Rather than claiming causation, the study evaluates whether congressional country or issues mentioned overlapped with NGO reporting during those same sessions. The findings show recurring overlap between congressional attention and NGO-identified countries, abuses, and normative claims. This convergence suggests that NGOs operated within a democratic information environment yet simultaneous …

Repeated Disasters, Evolving Plans: Flood Mitigation Strategy Change Across Pre- And Post-Disaster Planning Periods In High-Loss U.S. Communities, Jenifar Selim

Electronic Theses and Dissertations

This research explores how flood mitigation planning has evolved in counties exposed to multiple billion-dollar flooding disasters. The research focuses on two case studies: Jefferson County, Texas, and Jefferson Parish, Louisiana, two Gulf Coast communities with repeated flood exposure. Using comparative content analysis of pre- and post-disaster hazard mitigation plans, the study evaluates how local planning approaches and strategies shift following major flood events. Findings indicate that local governments largely remain reactive rather than proactive; however, these efforts are increasingly expanding beyond traditional infrastructure to incorporate broader resilience strategies, including nature-based solutions and regional coordination. The results highlight a gradual …

Examining The Relationship Between Past Involvement In Sexual Violence, Gender, And Rape Myth Acceptance In College Student-Athletes, Sarah Baker

Theses and Dissertations

Sexual violence (SV) is a persistent concern on U.S. college campuses, with student-athletes at higher risk for both perpetration and victimization. Rape myth acceptance (RMA) reflects beliefs that excuse or downplay SV, but it is unclear how these beliefs relate to student-athletes’ personal experiences with SV. This study examined RMA based on past SV involvement and gender, with attention to individuals reporting both perpetration and victimization. Participants were 350 NCAA Division III student-athletes who completed measures of SV perpetration and victimization, RMA, and sexism. Analyses evaluated differences in RMA by past involvement in sexual violence and gender while controlling for …

Optical Integrated Sensing And Communication: Deep Reinforcement Learning-Based Beam Tracking For Dynamic Vehicle-To-Everything Networks, Akshat Sharan

Theses and Dissertations

Optical Wireless Communication (OWC) promises ultra-high bandwidth for vehicular networks but suffers from critical beam misalignment in dynamic environments. The emerging paradigm of Optical Integrated Sensing and Communication (O-ISAC) addresses this challenge by unifying the sensing and communication functions over a single shared optical aperture, enabling real-time environmental awareness to guide beam steering. However, the multi-objective, stochastic nature of this joint optimization problem renders classical closed-form controllers inadequate. This thesis proposes and evaluates a deep reinforcement learning framework for continuous beam tracking in a 2D vehicular O-ISAC scenario. We conduct a comprehensive comparative study of four state-of-the-art deep RL algorithms: …

Investigations Into Biophysical Mechanisms Of Amphiphilic Molecules At Protein And Membrane Interfaces, Samuel Richard Pennock

Theses and Dissertations

Amphiphilic compounds play a key role in chemical biology due to their ability to associate with biochemical complexes through a diverse set of noncovalent interactions. Interactions between amphiphiles and biological targets elicit a wide array of modulatory effects, structural stability, and activity. However, due to the inherent complexity of these interactions, there has yet to be a broadly predictive framework for determining whether a given amphiphile-target interaction will be beneficial or deleterious. This thesis seeks to advance the mechanistic understanding of amphiphile-target interactions by investigating two distinct but unified systems. In the first study, the effects of fatty acid ionic …

The purpose of this qualitative Collaborative Action Research (CAR) study was to examine Rowan University’s understanding, interpretation, and implementation of service animal regulations and procedures and to suggest alternatives for legal and equitable access. The study was based on the social model of disability and used four CAR cycles. …

African American Women Counselors’ Lived Experiences Of Burnout Due To Microaggressions, Anquitra Walton

Walden Dissertations and Doctoral Studies

Within the counseling profession, African American women navigate unique challenges in the workplace, often experiencing microaggressions that contribute to stress, self-doubt, and emotional exhaustion. While systemic racial issues drive workplace microaggressions, counselor educators and supervisors remain ill-equipped to support African American women through the resulting burnout. The purpose of this qualitative study was to explore the lived experiences of African American women counselors to understand how microaggressions can lead to burnout and affect their psychological well-being. Guided by a transcendental-phenomenological qualitative framework, semi-structured interviews were conducted to capture participants’ experiences, exploring the lived experiences of African American women counselors who …

Effect Of Solid Particle Size And Density On Incipient Motion In A Turbulent Boundary Layer, Robert Bryan

Doctoral Dissertations and Master's Theses

Wind-blown sand and other instances of solid particles mobilized and suspended in gaseous turbulent boundary layers (TBLs) are seen in a wide variety of engineering contexts. An experimental framework was developed to study the incipient particle motion driven by external forcing within a turbulent boundary layer, which is provided by an airfoil section oscillating in the free-steam flow, resulting in a periodic disturbance in the near-wall region through production of synthetic large-scale structures at a fixed frequency. The incoming unsteady carrier-phase eddies were measured with a hot-film sensor upstream of a particle bed, and the particle motion was captured by …

Voices Of The Homeless: Phenomenological Portraits Of Parental Engagement Among Parents Experiencing Homelessness, Geneva Marie Winterbottom

Electronic Theses and Dissertations

Family homelessness is a widespread crisis that disrupts the educational experiences of thousands of children, including South Carolina where rates of family homelessness continue to grow. Although research has explored families and homelessness, limited research has focused on the parental engagement of homeless parents. This study explored the parental engagement among homeless parents in South Carolina.

Guided by van Manen’s (1990) interpretive phenomenology, four parents residing in a South Carolina homeless shelter participated in semi-structured interviews and created self portraits, which were analyzed using the hermeneutic circle to derive phenomenological insight.

Identifying Failure Behaviors In Stereolithography From Varied Print Orientations, Kevin Veltre

Theses and Dissertations

Stereolithography (SLA) is an additive manufacturing (AM) technique that utilizes photopolymerization to create three-dimensional shapes by strategically printing layers of material. Printing parameters such as layer orientation, print resolution and post cure can affect a specimen’s homogeneity, longevity and mechanical characteristics. Because of this variability, print parameters must be carefully considered when designing products and print processes for desired components, as manufacturers often fail to include all relevant print settings when advertising mechanical properties. For this study, 130 SLA-printed specimens were created with 100-micron print layer thickness and print orientations varying between 0 and 90, including intermediate orientations, to observe …

North Dakota’S New Health Initiative The Multi-Partner Health Collaborative, Krissie L. Mayer

Using systems theory (ST), the study explored how executive leadership, the steering committee, and goal groups function as interdependent subsystems whose alignment, communication, and feedback loops influence overall performance. Semi-structured interviews, analyzed thematically, reflected the patterns related to collaboration, SHIP implementation, barriers to effectiveness, and factors shaping long-term sustainability. Stakeholders generally viewed …

Deviant By Design: How Institutional Forces And Analyst Scrutiny Shape Financial Policy Deviance And Convergence, Jonathan W. Hensley

Electronic Theses and Dissertations

This dissertation explores the institutional and economic forces shaping corporate financial policy, specifically examining why firms deviate from industry-typical leverage and cash holdings, whether they converge toward these norms, and the performance implications of such trajectories. I develop a framework, rooted in institutional theory and dynamic capital structure literature, that characterizes firms with extreme, multi-year financial policies as "deviant by design." While managers might maintain non-normative leverage or cash positions for firm-specific efficiency gains, these choices often clash with established industry templates, leading to legitimacy costs and institutional pressure for conformity.

Using a longitudinal panel of U.S. public firms from …

Material Affecting Design (Mad): How Living Biomaterials Reshape Computational Design Through Biological Transformation, Abolhassan Pishahang

Electronic Theses and Dissertations

Living biomaterials grow during fabrication, making strategy selection a design problem distinct from conventional form-making. This dissertation investigates how Pleurotus ostreatus mycelium and Triticum aestivum plant roots reshape the computational design process through their biological behavior. The central argument is that when a designer works with living matter, the material participates in forming, changing the decisions made, the strategies chosen, and the framework required. This relationship between biological transformation and computational design is named the Material Affecting Design (MAD) framework. The research was conducted through a research-through-design methodology grounded in American pragmatist philosophy, particularly the work of Dewey, James, and …
