Caring In Social Studies: An Examination Of Teacher Preparation Standards, Vanializ Agramonte

USF Tampa Graduate Theses and Dissertations

Care is something we expect educators to demonstrate towards their students, but are theythemselves being taught the importance of care in education and prepared to enact it in their classrooms? The existing literature on care and care theory in education is limited, but shows a link between care and student success; many educators also point to anecdotal evidence of the importance of care. This study sought to examine themes of care in national standards for teacher preparation. Through the use of directed qualitative content analysis, three national teacher preparation standards (the Council for the Accreditation of Educator Preparation, the Interstate …

Community-Centered Early Warning For Outbreaks In Humanitarian Emergencies: Evaluating Community-Based Surveillance For Priority Communicable Diseases Among Internally Displaced Populations In Iraq, Caitlin M. Wolfe

USF Tampa Graduate Theses and Dissertations

Background: Community based surveillance (CBS) is the organized and rapid collection of information from health events identified in the community and includes the systematic detection and reporting of events of public health significance. While used globally to enhance the detection of priority diseases, CBS has not been routinely deployed in Iraq, where a once-robust health system has been devastated by decades of war, international sanctions, and large-scale population displacement. During infectious disease outbreaks, it is imperative to quickly detect and isolate suspect cases, investigate confirmed cases, and trace and monitor the contacts of confirmed cases. The COVID-19 pandemic underscored the …

Curricula As Ideology: A Study Of Cultural Representations In Arabic As A Foreign Language (Afl) Textbooks, Zakaria Fahmi

USF Tampa Graduate Theses and Dissertations

The present study examines cultural representations in two widely used AFL textbook series, namely Al-Kitaab and Arabiyyat al-Naas. Fundamentally, three main issues motivate this study: (1) the cultural politics of language textbooks underlying the construction and dissemination of cultural knowledge and its prioritization of the latter on grounds of subjectivity, ideology, and power, (2) the politicization of Arabic as a foreign language (AFL) in light of the post 9/11 language advocacy, and (3) the prevailing standard language ideology of al-Arabiya al-fuṣħaa (العربية الفصحى) and the pedagogical challenges posed by Arabic diglossia. The data comprise five textbooks from the aforementioned series, …

Effects Of Diminazene Aceturate On Drosophila Melanogaster: A Lipidomic Analysis, Gabriela Suarez

USF Tampa Graduate Theses and Dissertations

Pesticides are agents designed to eradicate living organisms to preserve agricultural needs.¹ Today the most commonly used pesticides are termed “modern pesticides”, they are characterized by lower lipophilicity and limited stability, making them less time persistent in the environment. Among these modern pesticides are organophosphorus, urea, phenoxy alkanoic, triazine, chloroacetanilide, and glyphosate-based pesticides.² The issue faced with most of these pesticides is that they affect more than just the targeted pest and pose a danger to not only humans, but also entire ecosystems.^1,3,4 While there are many different types of pesticides, insecticides show the most variance and …

African Spirituality In Literature Written By Women Of African Descent, Brigét V. Harley

USF Tampa Graduate Theses and Dissertations

African spiritual memory is the thread that connects members of the African diaspora, irrespective where we are or what we are doing. However, because of white supremacy, the longevity of African spiritual memory and its duration as a living, thriving, breathing force often becomes distorted under the weight of anti-black prejudice. This dissertation debunks the myth that people of African descent required outside input from non-Africans and Arabs to establish the world’s oldest and most studied civilizations, Ta-Seti and then the Egyptian Empire. Women writers of African descent capture the ever-present thread of African spiritual memory, providing a glimpse of …

Dissolved Nitrogen Removal In Biochar Amended, High Permeability Media For Urban Stormwater Treatment, Mark Vicciardo

USF Tampa Graduate Theses and Dissertations

Nutrient pollution in stormwater drives the eutrophication of inland and costal waterbodies which leads to sea grass retreat and the proliferation of harmful algal blooms (HAB). These anthropogenic effects destabilize ecosystems, and some HABs can pose direct human health risk. Bioretention, or the storage and controlled discharge of stormwater run-off in an ecologically engineered setting, is a potential solution to this problem. However, it relies heavily on the settling of particles as a nutrient removal mechanism, and thus struggles with pollutants, such as dissolved nitrogen, which is a particular problem in Florida where the geological prominence of phosphorus leaves nitrogen …

Evaluation Of A Treatment Package To Increase Food Variety For Children With Autism Spectrum Disorder With Food Selectivity, Julissa Robles

USF Tampa Graduate Theses and Dissertations

Individuals with Autism Spectrum Disorder (ASD) and other developmental disabilities are often likely to develop feeding disorders and certain food selectivity (Wood et al., 2009). Various approaches have been taken to assess food selectivity in children with ASD to increase food consumption. Koegel et al. (2012) found that participants were more likely to try new foods when provided with contingent reinforcement with the choice of their preferred item or toy along with hierarchical exposure to novel foods. The purpose of this study was to extend the findings from Koegel et al. (2012) and assess the effects of using hierarchical exposure …

Bird Strike Hazard Assessment For The Tampa International Airport, Florida, Usa, Yakubu Ogwu Isah

USF Tampa Graduate Theses and Dissertations

Managing wildlife at airports poses a challenge for ensuring safety for aviation traffic. Airports, with their surrounding habitats and infrastructure, serve as attractants for avian species. Threats created by these species have led managers to develop management techniques in and around airports (DeVault et al 2013). One approach is the use of geographic information systems (GIS) for analyzing avian strike data and airport bird surveys. Spatial analysis of strike data identifies species of threat by categorizing strike occurrence, species sizes, phase of flight, and risk of damage. In addition, GIS can be used to map hotspots of bird strikes. These …

Semi-Automated Cell Annotation Framework Using Deep Learning, Abhiram Kandiyana

USF Tampa Graduate Theses and Dissertations

Unbiased stereology refers to a field of applied mathematics \cite{intro-to-stereology} focused on accurate (model and assumption-free) quantification of three-dimensional (3D) objects, typically based on their appearance in 2D sections (planes) through the objects. In the biological sciences, these techniques are widely used for making unbiased estimates of arbitrary-shaped (stochastic) objects such as stained cells, blood vessels, region volumes, etc., in tissue sections through a region of interest (ROI).

This fundamental methodology is widely used for evaluating structural changes that occur in diseases, aging, and pharmaceutical interventions, thereby ensuring reliable outcomes. In terms of limitations, stereology is tedious, time- and labor-intensive, …

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 …

Lights, Camera, Recruitment: Analyzing Dod-Hollywood Synergy And Its Effects On Attitudes And Behaviors Towards The Military, Jose-Andres Leon-Gil

USF Tampa Graduate Theses and Dissertations

The purpose of this study is to research priming effects on DoD influenced films and uncover if there are significant effects affecting attitudes, beliefs, military support, and behaviors. This study is important because there is a lack of literature on the effects of DoD-influenced films. A portion of top grossing films are influenced by the DoD while there is little research on the effects consumers have. This study conducted an experiment testing the effects of behaviors and attitudes when a priming stimulus is presented. The priming stimulus was a military-influenced film clip and a military advertisement. Three groups were made, …

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

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 …

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 …

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 …

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

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

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

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 …

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

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

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 …

Human Motion Detection Evaluated Through An Evoked Cortical Potential Frequency Spectrum, Howard E. Painter

USF Tampa Graduate Theses and Dissertations

Electrical potentials were recorded from scalp of normal male subjects while they were viewing continuously moving sinusoidal gratings. Responses from the occipital cortex were amplified, digitized, stored and then transformed from the time domain to the frequency domain using a microcomputer based Fast Fourier Transform algorithm. High frequency components (Beta Activity) of the resulting power spectrum were analyzed for evidence on neural generators (electrical sources) in the striate cortex driven presumably by transient-cells (Y-cells or Magnocellular) responding to the continuously moving grating. Several stimulus parameters were examined: angular velocity, spatial frequency, direction (orientation), color, and intensity. A16 Hz component of …

Brain-Inspired Spatio-Temporal Learning With Application To Robotics, Thiago André Ferreira Medeiros

USF Tampa Graduate Theses and Dissertations

The human brain still has many mysteries and one of them is how it encodes information. The following study intends to unravel at least one such mechanism. For this it will be demonstrated how a set of specialized neurons may use spatial and temporal information to encode information. These neurons, called Place Cells, become active when the animal enters a place in the environment, allowing it to build a cognitive map of the environment. In a recent paper by Scleidorovich et al. in 2022, it was demonstrated that it was possible to differentiate between two sequences of activations of a …
