A Study Of Complex Systems: From Magnetic To Biological, Douglas Carroll Lovelady

USF Tampa Graduate Theses and Dissertations

This work is a study of complex many-body systems with non-trivial interactions. Many such systems can be described with models that are much simpler than the real thing but which can still give good insight into the behavior of realistic systems. We take a look at two such systems. The first part looks at a model that elucidates the variety of magnetic phases observed in rare-earth heterostructures at low temperatures: the six-state clock model. We use an ANNNI-like model Hamiltonian that has a three dimensional parameter space and yields two-dimensional multiphase regions in this space. A low-temperature expansion of the …

The Return Of The 1950s Nuclear Family In Films Of The 1980s, Chris Steve Maltezos

USF Tampa Graduate Theses and Dissertations

In the 1980s the cinematic nuclear family flourished again after the self-explorative 1960s and turbulent 1970s. This thesis explores the portrayal of the idealized American family in film between the 1950s and 1980s. The 1955 film Rebel Without a Cause reflects the 1950s cinematic family model. My investigation includes the role of the father figure and the bonds in intergenerational relationships. During the early 1980s, films such Ordinary People and ET: The Extraterrestrial reflect the need to reevaluate the 1950s ideal nuclear family. My examination of these films continues to include the importance of the father figure and bonds between …

The activity involved digital video recording and editing, mediators which were intended to facilitate the iterative review of and subsequent reflection and action upon the content of the video during its creation.

By investigating the process of contextual interaction between learners and the mediational elements of their environment as the activity progressed, …

Underwater Hearing In The Loggerhead Turtle (Caretta Caretta): A Comparison Of Behavioral And Auditory Evoked Potential Audiograms, Kelly Martin

USF Tampa Graduate Theses and Dissertations

Methods for collecting behavioral audiograms are often time consuming and require trained, captive subjects. It is more practical to measure hearing sensitivity using electrophysiological methods, such as auditory evoked potential (AEP) testing, in which electrodes measure action potentials in response to acoustic stimuli. These data can be collected in a matter of hours. However, results should be verified through behavioral testing. Current knowledge of marine turtle auditory abilities is based on a few electrophysiological tests. The purpose of this study was to collect and compare behavioral and auditory evoked potential audiograms in a captive adult loggerhead turtle (Caretta caretta …

Data on various coaching-related factors (i.e., perceived coaching quality, coach continuity, frequency and duration of training and technical assistance), …

School-Wide Pbs: The Link Between Action Planning And Outcomes, Stephanie Angelique Martinez

USF Tampa Graduate Theses and Dissertations

Most school based initiatives are not implemented long-term and do not reach sustainability (McDermott, 2000; Mirel, 1994; Rice & Malen, 2003). Schools are implementing School-Wide Positive Behavior Support (SWPBS) as an initiative to target social emotional development and behavior. Schools that have implemented SWPBS have experienced decreases in rate of Office Discipline Referrals (ODR), In-School Suspension (ISS) and Out-of-School Suspension (OSS) (e.g. Bohanon et al., 2006; Childs et al., 2009; Lassen et al., 2006). Research has also shown that schools that implement with a higher degree of fidelity have better outcomes (Childs et al., 2009; Florida's Positive Behavior Support Project, …

The Persistence Of Casuistry: A Neo-Premodernist Approach To Moral Reasoning, Richard Arthur Mercadante

USF Tampa Graduate Theses and Dissertations

The general purpose of this dissertation is to explore casuistry--case-based reasoning--as a discredited, rehabilitated, and, most importantly, persistent form of moral reasoning. Casuistry offers a much needed corrective to principle-based approaches. I offer a defense of a "principle-modest" casuistry and explore the epistemology of casuistry, describing the prerequisite knowledge required for casuistry. I conclude by arguing that casuistry is best understood as a neo-premodernist approach to moral reasoning.

Investigation Of The Optimal Dissolved Co2 Concentration And Ph Combination For The Growth Of Nitrifying Bacteria, Raymond Anthony Morris

USF Tampa Graduate Theses and Dissertations

Ammonium (NH₄⁺) is a biological nutrient that is transformed in a wastewater treatment plant (WWTP) in a process called activated sludge. This is accomplished in an aerobic environment using microorganisms and inorganic carbon that convert the ammonium to nitrate (NO₃^-). This process is termed nitrification. Removal of ammonium is necessary due to its oxygen demand and toxicity to the environment.

Nitrification is considered a slow process due to the slow growth rate of the nitrifying bacteria. Ammonia oxidizing bacteria (AOB) first covert the ammonium (NH₄⁺) to nitrite (NO₂^-) …

The Threat To Democracy In Brazil's Public Sphere, Daniel Nettuno

USF Tampa Graduate Theses and Dissertations

This thesis looks at the nature of violence with its endemic, and increasingly epidemic presence in Brazil. I analyze the structure of the justice system, police force, and the many governmental security programs in order to better explain why Brazil is so violent and its government has been unable to control this violence. Living under violent conditions, Brazil has become a society where the efficient functioning of the public sphere has been undermined. This public space, shared by citizens, is what many academics believe to be a critical component of a robust and functioning democracy. In Brazil, it is shown, …

Environmental Health In The Latin American And Caribbean Region: Use Of Water Storage Containers, Water Quality, And Community Perception, Erlande Omisca

USF Tampa Graduate Theses and Dissertations

Water quality and availability are important issues in many developing countries where portions of populations still lack access to potable water. Throughout the English-speaking Caribbean and parts of Latin America, households and businesses invest in water supply systems even when they are connected to and pay for water services from a private or state owned provider. Inconsistent supplies of water from the water companies have led many people to invest in storage tanks which, if operated correctly, can provide water throughout the day even when the supply from the main is low or zero. While these individual systems help to …

Contextualizing Hiv/Aids Prevention And Treatment Programs In Zanzibar, Tanzania, Naheed Ahmed

USF Tampa Graduate Theses and Dissertations

International aid organizations and wealthy nations have contributed billions to combat the spread and treatment of HIV/AIDS in sub-Saharan Africa; however, these programs have been critiqued for not addressing the socioeconomic and cultural context of the epidemic, instead relying upon generalized approaches. The prevalence rate in Zanzibar, Tanzania is low in the general population, but high among vulnerable segments of Zanzibari society, resulting in interventions focusing on particular groups (e.g. sex workers, drug users, and men who have sex with men). Through interviews with government agencies, non-profit organizations, medical professionals, vulnerable populations, and HIV/AIDS patients, this paper examines how local …

Thermal Response Of Lithium Tantalate For Temperature Measurement, Ardit Agastra

USF Tampa Graduate Theses and Dissertations

This thesis describes the study of the thermal response of the pyroelectric material named lithium tantalate or LT (LiTaO3) in aid of this material’s possible use for temperature measurement. The temperature range studied was between 5-99 oC. The sensor was excited using a silicon rubber heater.

Giving Meaning To Grief: The Role Of Rituals And Stories In Coping With Sudden Family Loss, Julia Janelle Barnhill

USF Tampa Graduate Theses and Dissertations

In this dissertation, I seek to better understand the sensemaking process among surviving family members after a tragic loss of a teenage or young adult child. Using social constructionism (Gergen, 1991) as a theoretical framework, I focused on how meanings of loss are constructed through the use of language and other symbols. I specifically looked at the role of family stories and rituals in making sense of the sudden loss as well as how a survivor's role as a sibling or parent may impact the grieving process. The participants in my research were all members of families in which a …

Influence Of Temperature On Yolk Resorption By Centropomus Undecimalis Larvae, Claudia Catalina Baron-Aguilar

USF Tampa Graduate Theses and Dissertations

In an effort to determine the optimal temperature for rearing Centropomus undecimalis larvae during the yolk resorption period, larval development was measured under four different temperature regimes (23, 25, 28 and 31 °C).

_Alien_ Thoughts: Spectatorial Pleasure And Mind Reading In Ridley Scott's Horror Film, Cecilia Madeline Bolich

USF Tampa Graduate Theses and Dissertations

Pleasure experienced in an unpleasant film genre, like horror, has prompted numerous discussions in film studies. Noted scholars like Carol J. Clover and Noël Carroll have rationalized spectatorial enjoyment of a genre that capitalizes on human anxieties and complicates cultural categories. Clover admits that horror initially satisfies sadistic tendencies in young male viewers but then pushes them to cross gender lines and identify with the strong female heroine who defeats the film's threat. Carroll provides a basic explanation, citing spectators' cognitive curiosity as the source of pleasure. Both scholars are right to consider emotional, psychological, and cognitive experiences felt by …
