Branching Corals Modulate Their Hydrodynamic Environment, Enhancing Capture Rates Of Evasive Prey, Kelsey Daniels

USF Tampa Graduate Theses and Dissertations

Reef-building corals obtain nutrients through two primary means: autotrophy (via mutualism with photosynthetic zooxanthellae) and heterotrophy (via feeding). The latter form of resource acquisition is understudied and many aspects of predator-prey interactions between coral and naturally occurring prey species remain unexplored. In this thesis, I elucidate the role of branching coral morphology in shaping the colony’s local hydrodynamic environment and describe how this environment impacts prey capture, particularly among evasive and hydrodynamically sensitive, but highly abundant prey such as copepods. I used acrylic cylinders of three sizes in aquaria to model the structure of coral branches across the range of …

Identification Of Host Nuclear Factors Exploited By Kshv Lana To Maintain Latency, Anandita Ghosh

USF Tampa Graduate Theses and Dissertations

Kaposi’s Sarcoma Associated Herpes Virus (KSHV or HHV-8) is a γ-herpesvirus implicated in multiple lymphoproliferative human cancers and immune dysregulatory diseases. Like other herpesviruses, KSHV has a biphasic mode of infection primarily orchestrated by two viral proteins: the Latency-Associated Nuclear Antigen (LANA), which promotes viral persistence through latency, and the Replication and Transcription Activator (RTA), which triggers lytic reactivation. During latency, the KSHV genome exists as a highly heterochromatinized, extrachromosomal episome in the nucleus, which can be reverted to euchromatin in response to certain stimuli, like stress. KSHV has evolved to exploit numerous host proteins to orchestrate its lifecycle, especially …

Strain In The System: Examining The Relationship Between Adverse Childhood Experiences And Pathways Into Cybercrime, Hannah R. Murphy

USF Tampa Graduate Theses and Dissertations

This study examines the relationship between adverse childhood experiences (ACEs) and cybercriminal behavior among 238 active hackers with verified website defacements identified through the Zone-H archive. Drawing upon General Strain Theory, this research investigates whether childhood trauma influences both the developmental timing and motivational aspects of hacking activities. Using ordinary least squares and ordered logistic regression analyses with country-clustered standard errors, the study tested two hypotheses: (1) that higher ACE scores would be associated with earlier onset of hacking behavior, and (2) that higher ACE scores would predict increased likelihood of engaging in revenge-motivated hacking. Results revealed a complex relationship …

Examining Associations Between Sleep Variability And Treatment Outcomes In A Clinical Sample Receiving Psychotherapy Treatment For Alcohol Use Disorder, Charles A. Manzler

USF Tampa Graduate Theses and Dissertations

Sleep disturbances are highly prevalent among individuals with AUD. Sleep and alcohol have a bidirectional relationship such that alcohol damages sleep-promoting brain regions, and impaired sleep exacerbates cognitive and emotional deficits that can promote alcohol use. Despite the evidence that sleep improves across treatment for AUD, these improvements have had inconsistent associations with treatment outcomes. This may result from previous research focusing solely on mean values of sleep parameters rather than daily within-person variability. Sleep variability is emerging as an important correlate of physiological dysregulation and is connected to a range of negative symptoms that may promote alcohol use. The …

Quantifying Wellbore Effects During Co2 Sequestration In A Saline Aquifer, Uzoma Johnpaul Ajugwe

USF Tampa Graduate Theses and Dissertations

Carbon capture and storage (CCS) is a strategy for mitigating climate change by reducing greenhouse gas emissions from large stationary sources like fossil-fuel-fired power stations. One method of CCS involves carbon dioxide (CO2) sequestration in deep saline aquifers, where supercritical CO2 is injected into an aquifer. The success of such projects depends on accurate predictions of CO2 behavior within the subsurface, which are obtained through numerical simulations.

TOUGHREACT, a renowned simulation tool, models subsurface fluid flow, geochemical interactions, and solute transport, providing insights into the feasibility of CO2 sequestration projects. A critical aspect of these simulations is the apportioning of …

Surface Acoustic Wave Energy Driven Degradation Of Aqueous-Based Methylene Blue, Xieqi Gu

USF Tampa Graduate Theses and Dissertations

This study investigates the degradation behavior of methylene blue (MB) under surface acoustic wave (SAW) excitation, focusing on the effects of power, frequency, hydrogen peroxide (H2O2) concentration, and the use of perovskite oxide catalysts (LFO and LSF). Initial experiments showed that MB concentrations remained stable under SAW at ~10 MHz and ~30 MHz with power levels of 1–3 W in the absence of H2O2, though solution temperatures increased. Upon introducing 1 M H2O2, MB degradation followed a second-order rate constant, with degradation rates increasing with power and significantly higher at ~30 MHz, suggesting that both frequency and power enhance free …

Creative Climates: The Impact Of Different Environmental Exposure On Group And Individual Creativity, Michael P. Hopkins

USF Tampa Graduate Theses and Dissertations

This thesis examined the influence of indoor versus outdoor environmental exposure and individual versus group participation on verbal creativity performance. Guided primarily by Attention Restoration Theory (ART; Kaplan & Kaplan, 1989), it was predicted that outdoor natural settings would enhance creativity through restorative cognitive processes. Additionally, it was hypothesized that groups would outperform individuals due to the cognitive advantages of collective induction and information pooling. Participants (N = 256) completed verbal creativity tasks—Remote Associates Task (RAT; convergent creativity) and Alternate Uses Task (AUT; divergent creativity)—following a 30-minute exposure period in either an indoor student center or outdoor botanical garden setting, …

Investigating Momentary Body Image Disturbance, Affect, And Disordered Eating Among College Students, Allison T. Cunning

USF Tampa Graduate Theses and Dissertations

Despite evidence that eating disorders are associated with elevated mortality rates, increased risk of suicide, and societal and financial burden, treatment outcomes for individuals with eating disorders remain poor. Body image disturbance has emerged as a robust risk factor for the development and maintenance of disordered eating (e.g., overeating, binge eating, purging, restriction) and theoretical and clinical perspectives most commonly operationalize body image disturbance as a trait construct. However, empirical evidence suggests body dissatisfaction may fluctuate, and these fluctuations may play an important role in the relationship between risk factors and disordered eating. The current study employed ecological momentary assessment …

Exploring The Connection Between Mental Health Stigma, Social-Emotional Risk, And Help-Seeking Behaviors Among High School Students, Dorie Ross

USF Tampa Graduate Theses and Dissertations

Throughout the United States, the rate of adolescents experiencing mental health-related challenges continues to rise, impacting their social-emotional well-being. Despite increasing concerns, the majority of adolescents do not seek treatment for mental health problems. One barrier contributing to a lack of help-seeking behaviors is mental health stigma. Furthermore, for students who have sought help for such concerns, there is a lack of consensus on whom high school students turn to for support when seeking help. The current study utilized quantitative methodology in the form of Structural Equation Modeling to examine the complex relationship between social-emotional risk, perceptions of mental health …

Race To The Bottom: Is Seabed Mining Worth The Cost?, Linda Nhon

GNSI Publications

There is a recent resurgence in seabed mining, particularly in the potential excavation of polymetallic nodules (PMN) for cobalt, nickel, and copper in response to the tight competition for critical minerals between the United States and China. From the 1970s to the 1980s, increased government funding in the seabed mining industry sparked a surge of academic research and international collaboration in deep-ocean exploration. Although not the sole driver of this ballooning interest, Project Azorian—the CIA’s audacious mission aboard the Glomar Explorer to recover the sunken Soviet nuclear submarine K-129—was undeniably catalytic in generating enthusiasm. Purportedly constructed by the aviation mogul …

Simulation Of Multi-Receiver Solar Power Tower By Enhancement Of Solarpilot Software And A Review Of Absorber Coating Materials For The Receivers, Yasser Mirza Baig

USF Tampa Graduate Theses and Dissertations

Central receiver concentrating solar power (CSP) towers offer significant potential for cost-effective renewable electricity but face increasing optical losses with larger heliostat fields. This thesis introduces enhancements to NREL’s SolarPILOT software through a Python-based API named CoPylot, which enables comprehensive optimization of heliostat field layouts for multi-receiver systems. The enhanced methodology incorporates per-heliostat ray tracing, receiver orientation optimization (tilt angle β), and an incidence-angle-dependent absorptance (α(θ)) model to evaluate optical performance, thermal losses, and techno-economic metrics within an integrated simulation framework.

A case study for Daggett, California demonstrates that transitioning from a baseline single-receiver system (180 m tower, 5×5 m …

Bat Occurrence And Microclimatic Conditions Of The Sima Del Órgano Cave, Mexico, Luis A. Hernández, Jaime E. Gómez, Cyntia Reyes

International Journal of Speleology

Caves represent an important type of shelter for many species of bats, particularly in karstic regions. In Mexico, about 60 bat species regularly use caves as roosts. The microclimate of a cave is a key component of the overall cave ecosystem. So, an adequate microclimate can minimize the energetic costs of bats associated with thermoregulation, gestation, embryonic development, parental care, lactation and social interaction. Cave environments are among the least known and most threatened on the planet, which is why we aimed to determine the monthly occurrence of bat species in the Sima del Órgano Cave, estimate the population size …

Development And Photophysical Characterization Of Bioinspired Materials, Qaisar Maqbool

USF Tampa Graduate Theses and Dissertations

Porphyrins are versatile aromatic macrocycles with unique photophysical properties that make them attractive for applications in light harvesting, photocatalysis, and sustainable energy conversion. Incorporating porphyrins into metal-organic frameworks (MOFs) offers a unique opportunity to modulate their photophysical behavior through spatial confinement and host–guest interactions. This thesis explores how structural modifications influence porphyrin excited-state behavior through a multi-stage investigation. The work begins by comparing the photophysical properties of two cationic porphyrins: tetra(N-methylpyridyl) porphyrin(TMPyP) and tetra(4-N,N,N-trimethylanilinium) porphyrin(4TANP). While TMPyP exhibits significant singlet–charge transfer (S₁–CT) state mixing due to charge delocalization onto peripheral pyridinium groups, 4TANP lacks comparable behavior. The localized nature of …

Evaluating The Protective Role Of Epo-R76e In Oxidative Stress-Induced Cell Death In Retinal Pigment Epithelium, Jemima Alam

USF Tampa Graduate Theses and Dissertations

Age-Related Macular Degeneration (AMD) causes dysfunction and loss of Retinal pigment epithelium (RPE). The degeneration and death of RPE cells causes irreversible visual impairment. Oxidative stress is a widely accepted triggering factor for RPE dysfunction. A hormone called Erythropoietin (EPO) is responsible to facilitate the erythropoiesis process, prevents progenitor cells from apoptosis and protects photoreceptors downregulating retinal degeneration. In this study, we aim to elucidate the role of EPO in downregulating oxidative stress in RPE. It is hypothesized that EPO will have a positive impact on suppressing oxidative stress and ferroptosis-mediated RPE degeneration due to its vital role in apoptosis …
