Roots Of Coded Metaphor In John Dee's Monas Hieroglyphica, Joshua Michael Zintel

USF Tampa Graduate Theses and Dissertations

An enormous amount of research on John Dee has materialized within the last forty years. Contrary to research published earlier in the twentieth century, such relatively recent studies have considered Dee’s idiosyncratic plurality of parallel traditions instead of trying to pigeonhole his activities into one of several discrete camps. That research (much of which is listed in the Bibliography) has been helpful hypothesizing what his Monas Hieroglyphica (1564) may mean for several fields of study in an interstitial capacity. Students of Early Modern mathematics, neoplatonism, and the histories of alchemy, chemistry, Christian kabbalah, and astronomy are among the many diverse …

Embodying The Empire: Imperial Women And The Evolution Of Succession Ideologies In The Third Century, Christina Hotalen

USF Tampa Graduate Theses and Dissertations

Julia Domna, Otacilia Severa, and Galeria Valeria occupy watersheds in the evolution of third century dynastic succession ideologies. The administrations of each emperor crafted propaganda designed to elicit support for their reigns and dynastic ambitions, each tailored to appeal to a particular audience. Images of the empresses in official media were carefully constructed to elicit a population’s support for the emperor’s legitimacy. Subjects responded to these messages, seeking to have …

Chemical Investigation Of Floridian Mangrove Endophytes And Antarctic Marine Organisms, Bingjie Yang

USF Tampa Graduate Theses and Dissertations

Nature creates diseases and illnesses for mankind, however, nature also provides therapeutics by making biological systems produce secondary metabolites. Although the secondary metabolites originally play roles in chemical defense or evolution, researchers have been working on them for drug discovery. Plants, fungi and marine organisms have been mostly explored by natural products chemists over the century and contributed most drugs to the market. With the increasing need of new drugs resulting from drug resistance and pathogen evolution, the natural products area has been focused on developing innovative methodologies to achieve higher efficiency of isolating new bioactive compounds.

A Narrative Inquiry Into A Principal’S Understanding Of School Culture And Its Influences On Principal Leadership, Robert M. Holby

USF Tampa Graduate Theses and Dissertations

Culture has been discussed and written about at great length from roots in anthropology (e.g., Tylor, 1920; Mead, 1928) to development of the concepts of organizational culture (Schein, 1985, 2010) and school culture (e.g., Bolman & Deal, 2013; Deal & Peterson, 1991, 2009). Societies, organizations and schools as organizations create, develop, and maintain culture—deep-seated assumptions, values, ways of thinking and acting that characterize how we do things, how we live.

In a school the principal is often cast as responsible for influencing or creating a culture and climate for change (Fullan, 2008; Jones et al., 2013). Thus, it is important …

Evaluating The Effects Of Multiple Exemplar Training On Mand-To-Tact Transfer In Children With Autism, Santiira Michelle Williams

USF Tampa Graduate Theses and Dissertations

Children with an Autism Spectrum Disorder (ASD) often require direct instruction to acquire communication skills and such skills are targeted in intensive communication training programs using the principles of applied behavior analysis (e.g., Peters-Scheffer et al., 2010). Because such intensive training programs can be costly and time consuming (National Conference of State Legislatures, 2017), any research on collateral effects of communication training can be beneficial. Mands and tacts are among the verbal operants targeted in communication training and research surrounding the functional independence of mands and tacts has yielded mixed results (e.g., Twyman, 1996; Petursdottir et al., 2005). The current …

Using Optimization Methods For Solving Problems In Sustainable Urban Mobility And Conservation Planning, Zulqarnain Haider

USF Tampa Graduate Theses and Dissertations

This dissertation considers three separate optimization problems related to sustainable urban and environmental systems. The first problem relates to the nightly relocation and recharging operations for Free-floating electric vehicle sharing (FFEVS) systems. Such operations involve a crew of drivers to move the shared electric vehicles (EVs), and a fleet of shuttles to transport those drivers. Mixed integer programs are used to model the relocation and recharging operations. Two approaches are devised: sequential and synchronized approaches. In the sequential approach, the movement of EVs is first decided, then the routing of shuttles and drivers is determined. In the synchronized approach, all …

Changing The Culture Of Consent: Teaching Young Children Personal Boundaries, Marlesha C. Bell

USF Tampa Graduate Theses and Dissertations

Currently, eight states and Washington D.C. mention consent education in their sex education standards (Naide, 2020). Most school-based consent education curricula focus on teaching pre-teens through adults consent within the context of sexual contact (Planned Parenthood, 2016). However, consent may be relevant for behavior outside the context of sexual contact. Young children could develop a repertoire for consent skills and use it to set and respect boundaries. Furthermore, behavior analysis has teaching technologies that could be used to inform a curriculum for teaching consent, such as behavioral skills training (Johnson et al., 2006) and video modeling (Charlop & Milstein, 1989). …

Care In Context: Constructing A Theory Of Care In One Fifth Grade Classroom, Emily J. Wingate

USF Tampa Graduate Theses and Dissertations

With a culmination of evidence suggesting the perception of caring relationships is associated with students' well-being (Natvig, Albrektsen, & Qvarnstrøm, 2003; Siddall, Huebner, & Jiang, 2013; Suldo, Friedrich, White, Farmer, Minch, & Michalowski, 2009), there is a need to better understand the ways in which care operates in the classroom. Further, there is a need to move beyond a prescription of caring behaviors to investigate the ways in which care, control, and conflict interact to impact classroom relationships. In the current study, I took a mini-ethnographic case study approach to investigate the concept of care within one fifth grade classroom. …

Evaluating Public Posting, Goal Setting, And Rewards To Increase Physical Activity In Children, Bryon G. Miller

USF Tampa Graduate Theses and Dissertations

In Experiments 1 and 2 we evaluated a pedometer-based intervention consisting of public posting between two teams of students, with additional self-monitoring, goal setting, and reinforcement components, to increase physical activity during school recess. In the absence of self-monitoring, performance feedback alone did not increase physical activity levels above those observed during baseline. Additionally, higher levels of physical activity were observed when goal-setting was introduced, with the highest levels of activity observed when raffle tickets could be earned for exceeding a specified step-total goal. In Experiment 3 we removed the team component and evaluated similar intervention components across an entire …
