Under Pressure: The Soft Robotic Clap-And-Fling Of Cuvierina Atlantica, Daniel Mead
Under Pressure: The Soft Robotic Clap-And-Fling Of Cuvierina Atlantica, Daniel Mead
USF Tampa Graduate Theses and Dissertations
Evolution over billions of years has led to unique animals of all types. The tiny sea butterfly is one that remains mostly anonymous because of its size and low place on the food chain, but it is a swimming creature that when examined closely reveals a surprise. Shockingly, it has a swimming motion nearly identical to small insects flying at intermediate Reynolds numbers, referred to as the clap-and-fling. The centimeter long pteropod flapping briskly at 5Hz escapes attention with its size and speed. Modeling the clap-and-fling motion of the sea butterfly at a larger scale allows the benefits and uniqueness …
Nutrient Removal Of Biochar Amended Modified Bioretention Systems Treating Nursery Runoff, Nicholas Richardson
Nutrient Removal Of Biochar Amended Modified Bioretention Systems Treating Nursery Runoff, Nicholas Richardson
USF Tampa Graduate Theses and Dissertations
Excess inputs of nutrients, such as nitrogen and phosphorus, to surface water bodies can lead to the presence of harmful algal blooms (HABs). HABs can damage their surrounding environments and the economies dependent on them. Nutrient pollution can be properly controlled and monitored at point-sources, such as wastewater treatment plants, but is more difficult to control for non-point sources, such as fertilizer runoff. One form of fertilizer runoff that remains overlooked is runoff from plant nurseries. Controlled release fertilizers (CRFs) embedded in plant containers at nurseries can leach excess nutrients into the runoff. For nurseries in Florida, best management practices …
The Theoretical Epigenetic Relationship Between Complex-Ptsd And Adhd In Holocaust Survivors’ Descendants, Y. Sahara Brodsky
The Theoretical Epigenetic Relationship Between Complex-Ptsd And Adhd In Holocaust Survivors’ Descendants, Y. Sahara Brodsky
USF Tampa Graduate Theses and Dissertations
When comparing ADHD and Complex-PTSD, these two disorders share many overlapping features in both areas of the brain that are affected and the behavioral aspects due to deficits in certain brain regions, such as the prefrontal cortex. It is due to this similarity that I predict that c-PTSD is the precursor to the development of ADHD in later generations. Through epigenetic changes that are consistent with c-PTSD diagnosis, these changes to the brain are then passed down the generational line. When this is combined with trauma transference and generational trauma, it creates a situation where both the behaviors inform how …

From Displacement To Intersubjectivity: A Phenomenology Of Sound In Classic Film Noir, Thomas Goodchild
From Displacement To Intersubjectivity: A Phenomenology Of Sound In Classic Film Noir, Thomas Goodchild
USF Tampa Graduate Theses and Dissertations
This paper analyzes the use of sounds displaced from their sources in classic filmsnoir. Noir is often understood as a dark and solipsistic moment in American cinema. Interpretations of noir frequently emphasize isolated individuals who are physically, psychologically, and socially displaced from their environments. Although scholarship on noir has examined this alienation through various sonic motifs such as music and voice-over, I investigate how several noirs draw attention to the act of listening through acousmatic sound—that is, sound heard without a visible source. Far from being an ephemeral auditory experience, I argue that the separation between sound and image invites …
Health Status In An Urban-Dwelling, Subtropical Frog Species (Lithobates Sphenocephalus) And Its Relation To Ranavirus And Hemoparasites, Gabrielle M. Wickersham
Health Status In An Urban-Dwelling, Subtropical Frog Species (Lithobates Sphenocephalus) And Its Relation To Ranavirus And Hemoparasites, Gabrielle M. Wickersham
USF Tampa Graduate Theses and Dissertations
Urbanization poses significant challenges to wildlife, including amphibians. The present study uses a multi-parameter approach that incorporates veterinary techniques to investigate the current health status of the adult southern leopard frogs (Lithobates sphenocephalus) in Tampa Bay, Florida, amidst urban stressors including nutrient loading, fragmented habitats, and light and noise pollution. Novel values for fluctuating asymmetry (e.g., variation between left and right bilateral traits; FA), body condition (CF), stress (e.g., neutrophil:lymphocyte (N:L) ratio), and inflammation (e.g., neutrophil morphologic abnormalities, parasite load) are reported. I also investigate the relationship of overall health with ranavirus presence and hemoparasite infections. Ranavirus was absent in …
On The Possibility Of Secular Morality, Zachary R. Alonso
On The Possibility Of Secular Morality, Zachary R. Alonso
USF Tampa Graduate Theses and Dissertations
Is something like a transcendent God necessary to have a coherent moral system, or at the very least, necessary for one to have personal ethical guidelines to live by that are not entirely subjective? This paper explores the claims of two Christian thinkers, David Bentley Hart and D. C. Schindler, as well as some alternatives to their thinking in the ethics of Alasdair MacIntyre and Jeffrey Stout. Hart and Schindler portray society as downcast, riddled with moral decay, and the only solution to this decay is to turn toward God, thereby recognizing a hierarchical, cosmological worldview. While MacIntyre believes that …
Preliminary Investigation Of Differences In Host Mitochondria Membrane Potential During Toxoplasma Gondii Infection, Bryan L. Ortega
Preliminary Investigation Of Differences In Host Mitochondria Membrane Potential During Toxoplasma Gondii Infection, Bryan L. Ortega
USF Tampa Graduate Theses and Dissertations
Toxoplasma gondii is an obligate intracellular protozoan with a broad host range of hosts, including various warm-blooded mammals, including humans. While infections can often be asymptomatic in immunocompetent individuals, they can pose significant risks to those who are immunocompromised, as well as pregnant women. Toxoplasmosis represents a significant burden on public health in the United States, with over 800,000 annual infections reported, often leading to severe complications such as symptomatic eye disease and congenital infections. Recent attention has developed regarding its potential association with human neuropathies such as Alzheimer's disease, dementia, and mood disorders. This project investigated differences in host …
The Effect Of The Covid-19 Pandemic On The Environmental Perceptions Of College Students, Sydney H. Kaylor
The Effect Of The Covid-19 Pandemic On The Environmental Perceptions Of College Students, Sydney H. Kaylor
USF Tampa Graduate Theses and Dissertations
In this study, the environmental perception changes in college students during the COVID-19 pandemic were investigated. During the almost worldwide lockdown between March and December 2020, many students experienced dramatic changes in their socioeconomic life that have affected their well-being, ability to learn, and environmental perceptions. Students were sent home from college campuses, many businesses were shut down, and changes were seen in the environment throughout the world. The many industries and businesses that were shut down decreased the pollution that was in the atmosphere, in our water, and on the land. In many places, lockdown policies lead to improved …
Temporospatial Deep Learning Strategies For Prediction Of Disease Progression In Radiology, John D. Mayfield
Temporospatial Deep Learning Strategies For Prediction Of Disease Progression In Radiology, John D. Mayfield
USF Tampa Graduate Theses and Dissertations
While the fields of machine learning and medicine are deeply rooted in axiomatic scientific principles, there is an element of art that makes the practice imperfect, yet innately human. As the two fields have seen the greatest overlap in their collective history, there remains a chasm between them in terms of practical translation for the patients who desire and deserve personalized medicine. As presented in this dissertation, I and my collaborators have contributed to the groundwork for future exploration of predicting disease progression by identifying signals within sequential medical imaging to provide a temporospatial relationship upon which we can make …

Access Management Curriculum For University Planning And Engineering Programs, Kristine Williams, Tia Boyd, Karen Dixon
Research Reports
Extensive research has been conducted on the topic of roadway access management and smart land use planning, documenting many benefits of these integrated practices to safety, congestion reduction, and livability. Consequently, many agencies across the US and abroad have instituted multidisciplinary and multimodal access management programs and projects. Yet few Universities educate planning and engineering students on the theory, practice, and benefits of access management. As a result, emerging professionals are entering practice with little or no knowledge of the topic and its critical importance to the transportation system. This project will fill that gap by providing a research-based curriculum …

Differentiating Magic: A Call For A Differential Approach, Weston L. Wright
Differentiating Magic: A Call For A Differential Approach, Weston L. Wright
USF Tampa Graduate Theses and Dissertations
This paper seeks to propose an alternative approach for studying magic. It is often the case inacademia, when studying magic, scholars use an understanding of modernity which favors a scientific perspective. When doing so, some scholars have concluded magic has become extinct in our modern society; despite recent research suggesting magical practice is thriving. Likewise, this scholarship promotes an idea of magic grounded in fear, ignorance, superstition, and fraudulence. The goal of this paper is two-fold. First, I seek to advocate for an approach to magic that allows for a plurality of perspectives to be acknowledged, not just a scientific …
Androgen Drives Melanoma Invasiveness And Metastatic Spread By Inducing Tumorigenic Fucosylation, Qian Liu
Androgen Drives Melanoma Invasiveness And Metastatic Spread By Inducing Tumorigenic Fucosylation, Qian Liu
USF Tampa Graduate Theses and Dissertations
Melanoma incidence and mortality rates are historically higher for men than women, with an estimated ~47% more new cases and twice the lethality in men in the US in 2023. Consistent with these discrepancies, emerging studies have highlighted the tumorigenic role of the male sex hormone androgen and its receptor (AR) in promoting melanoma aggressiveness. However, underlying cellular and molecular mechanisms and their precise pathological contributions are not well-defined. We recently discovered a sex-associated disparity in melanoma fucosylation, the post-translational modification of proteins with the dietary sugar L-fucose. Fucosylation, the conjugation of fucose moieties onto different glycan linkages on target …

Exploring The Swimming Behavior Of A Hydromechanical Copepod In The Context Of Positive Density Dependence, Eva J. Muir
Exploring The Swimming Behavior Of A Hydromechanical Copepod In The Context Of Positive Density Dependence, Eva J. Muir
USF Tampa Graduate Theses and Dissertations
This dissertation investigates the swimming behavior and population dynamics of the marine copepod, Acartia tonsa. This copepod is of interest as it utilizes hydromechanical signals within the environment to navigate its surroundings, resulting in a distinctive hop/sink swimming pattern. This adaptive trait serves several purposes including searching for mates, obtaining food, and detecting predators, however the evolution of this unique swimming style has not been explored. To address this knowledge gap, the first chapter of this dissertation explores the swimming characteristics and escape responses of captive-reared and wild-caught A. tonsa. When reared in aquaculture, A. tonsa populations experience higher populations …

Elucidating The Role Of The Tumor Suppressor Gene Rna-Binding Motif 5 (Rbm5) In Models Of Traumatic Brain Injury, Kara L. Snyder
USF Tampa Graduate Theses and Dissertations
Traumatic brain injury (TBI) is a worldwide health burden that causes death and disability. Clinical management of TBI involves guideline-based protocols to limit secondary brain injury but there remains an unmet need for therapeutics to target neuroprotection and to improve cognitive outcomes in patients. This dissertation concerns the examination of RNA binding motif 5 (RBM5) as a potential therapeutic gene target to promote neuroprotection in models of TBI. RBM5 is a potent pro-death tumor suppressor gene in cancer. We hypothesized that it also promotes cell death in neurons in the brain and therefore its inhibition would decrease neuropathology following CNS …

Energetic Value Estimates Of Wild And Domesticated Food Items Consumed By Congolese Bayaka Foragers, Lucie Benoit, Sheina Lew-Levy, Yann R. Ouamba, Alyssa N. Crittenden
Journal of Ecological Anthropology
We present a dataset that systematically estimates the energetic value of wild and domesticated food resources collected and consumed by Congolese BaYaka foragers. This dataset is unique in that it accounts for everyday practices of food processing and consumption. Reported values of inedible portions, moisture content, and estimated energetic values (kcal/g) were extracted from field research and the published food chemistry and nutrition literature. These data are central to understanding how nutritional needs are met in rainforest environments and will allow for current and future tracking of diet composition in this and similar ecologies. The dataset is available at https://doi.org/10.6084/m9.figshare.19446938.v9

Plumage aberrations in birds are not unusual and have been sporadically mentioned in literature, in which different patterns and variations are described. Leucism is an inherited disorder, characterized on birds by the lack of pigments in part or all of the plumage, and normal coloration of soft parts such as the bill, eyes, and legs. We present here the fi rst record of total leucism in Magnifi cent Frigatebird Fregata magnifi cens, and the fi rst for the species in Venezuela. Long-term studies are needed in the Neotropical region to evaluate survival and breeding success in leucistic birds.
