Thermal Ecology And Swimming Performance Of Native Tadpoles Dryophytes Femoralis In Central Florida, Jessalyn Aretz

USF Tampa Graduate Theses and Dissertations

Urbanization and climate warming have contributed to global amphibian declines in recent decades. Amphibians are particularly vulnerable to climate and urban-induced warming because their physiological processes are dependent on temperature across all life stages, but few studies have been done on tadpole responses to warming in comparison to adult responses. The study objective was to determine how the thermal ecology and swimming performance of a native Florida tadpole varied with rearing temperature and urban level, and whether these traits are plastic or adaptive. We collected eggs from wild populations of pine woods treefrog (Dryophytes femoralis) tadpoles at an urban and …

An Ecofeminist Ontological Turn: Preparing The Field For A New Ecofeminist Project, M. Laurel-Leigh Meierdiercks

USF Tampa Graduate Theses and Dissertations

Ecofeminists have predominantly refuted oppressive conceptual frameworks by rejecting dualistic logic and value hierarchies, despite the foundational view of ontology that underlies our logic and value systems. I argue that ecofeminists must engage in the creative process of articulating an ecofeminist ontology. I demonstrate that the omission of ontological discourse in ecofeminist scholarships is primarily due to the time period during which ecofeminism gained peak traction and their concerns with essentialism. I also show that feminists experienced an ontological turn in the 2000s that produced a new model for ontological theories that would be beneficial for ecofeminists to embrace. In …

Hidden Monstrosities: The Transformation Of Medieval Characters And Conventions In Shakespeare's Romances, Lynette Kristine Kuliyeva

USF Tampa Graduate Theses and Dissertations

When Shakespeare’s First Folio was published in 1623, it was entitled Mr. William Shakespeare’s Comedies, Histories, and Tragedies, the title designating the three genres under which his plays would be categorized for the next 250 years. Later, Irish critic Edward Dowden took it upon himself to restructure the Shakespearean canon by adding plays that were not previously published in the First Folio, reclassifying the genres of several of the plays, and establishing a new genre to accompany the previous three: romance. Within this fourth generic category of romance, Dowden situated four of the Shakespearean plays: Pericles, Prince of Tyre; Cymbeline; …

Introductory Geology Laboratory Students' Learnings From And Perceptions Of Physical And Virtual Polarizing Light Microscopes – An Exploratory Mixed Methods Study, Christy M. Bebeau

USF Tampa Graduate Theses and Dissertations

Undergraduate geoscience laboratory courses provide hands-on learning about earth materials. However thin section analysis is not typically included in introductory geology laboratories, likely due to the polarizing light microscope (PLM) costs. Therefore, there is a lack of research about the educational outcomes of novices learning these skills.

In this inquiry, I conducted mixed methods research about novice students' learning of thin section analysis in an introductory geology laboratory and evaluated learning and perception differences between students who used a virtual PLM and those who used a physical PLM. I collected data from Creative Exercise (CE) assessments in student midterm and …

Hurricane Impacts On Water Resources: A Look At Nature-Based Solutions To Improve Long-Term Resilience, Fautemeh Sajadi Bami

USF Tampa Graduate Theses and Dissertations

Severe storms are a common occurrence in the state of Florida. Hurricane events may cause hazards such as flooding, property damage, death, and many others. Such far-reaching impacts may potentially result in dangerous consequences where they occur. Of interest to this study were the impacts on water resources and water quality caused by storms. Hurricanes can bring about a deluge. An apparent excess of water may cause the notion of water scarcity to seem less significant. However, problems with potable water can be quite frequent due to storms.

This research sought to address the impacts of severe storms on water …

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 …

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 …

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 …

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, …
