The Effects Of A Structured Adherence Intervention To Haart On Adherence And Treatment Response Outcomes, Donald E. Kurtyka

USF Tampa Graduate Theses and Dissertations

Background: Adherence to antiretroviral (ARV) medications in excess of 90-95% is necessary for optimal response to suppress HIV replication and to maintain and/or restore immune function. A number of interventions have been shown to improve ARV adherence, but no research has been conducted which evaluates proactive monitoring of pharmacy refill adherence and subsequent intervention when inadequate adherence is identified.

Purpose: The purpose of this project was to compare treatment response, pharmacy refill adherence and self-reported medication adherence between two groups of patients: those participating in an AIDS Drug Assistance Program (ADAP) and those participating in a Medicaid-funded medication access program. …

Parent-Child Interaction Therapy For Children Diagnosed With Reactive Attachment Disorder, Demetria Soulounias-Arriaga

USF Tampa Graduate Theses and Dissertations

Parent-Child Interaction Therapy is a probably efficacious, evidenced-based

treatment, which has been proven to decrease problem behaviors of children, as well as

improve parent-child interactions. The first phase is the Child-Directed Interaction (CDI),

which allows the child to lead the play session, while parents are taught to interact

without giving demands, asking questions, or providing criticism. According to the

DSM-IV-TR, Reactive Attachment Disorder is a rare diagnosis. Many attachment

therapists indicate that traditional approaches to treatment have not been demonstrated as

being effective with these children. This study will examine the CDI phase of Parent-

Child Interaction Therapy as a …

Reforming Dance Pedagogy: A Feminist Perspective On The Art Of Performance And Dance Education, Jennifer Clement

USF Tampa Graduate Theses and Dissertations

Dancers, in their formal training, are deprived of many basic human experiences and are often not exposed to critical thinking. Expectations about what it means to dance and/or be a dancer shape the classroom environment, performances and both the body and mind of individuals engaged in this particular art form. A professional dancer is expected to plan her day around the dance classroom and this mentality is shared by aspiring professionals as well as dance educators. This structure, in tandem with the expectations for a female dancer to maintain a certain body type- almost always a thin flexible body, toned …

Land Use Policy And Practices In Karst Terrains, Spencer Fleury

USF Tampa Graduate Theses and Dissertations

Karst topography is the result of a specific combination of geological conditions, precipitation, biota, and temperature, and is characterized by the gradual solution of the underlying bedrock and the development of underground drainage routes for surficial runoff. Many of these karst landscapes are found in urbanized areas, where the potential for anthropogenic impact is quite high. In many instances, municipalities on karst terrains choose to mitigate these impacts by implementing ordinances that place restrictions on permissible land uses near karst landforms. This dissertation asks the question: are the impacts of karst-related land use regulation on human / social systems significant …

Trace Metals And Stable Isotopes As Tracers Of Life History And Trophic Connections In Estuarine-Dependent Fish From Tampa Bay, Florida, Linae Marie Boehme-Terrana

USF Tampa Graduate Theses and Dissertations

To examine the flow of trace metals through the Tampa Bay estuary, four fish species representing different trophic levels were analyzed for copper (Cu), zinc (Zn) and stable isotopes of carbon (C) and nitrogen (N). Species selected were the striped mullet (Mugil cephalus), tidewater mojarra (Eucinostomus harengulus), bay anchovy (Anchoa mitchilli), and sand seatrout (Cynoscion arenarius). Juvenile fish were collected from the Alafia, Hillsborough, Palm, and Little Manatee Rivers. Adults were …

"Under The Bloody Hatchet Of The Haitians": Thomas Jeffersonís Foreign Policy Concerning The Haitian Revolution, 1791-1806, Joseph A. Boyd

USF Tampa Graduate Theses and Dissertations

At first glance Thomas Jefferson's presidential actions concerning the Haitian Revolution seem to denote racially motivated decisions predicated upon fear. However, through a deeper analysis of primary documents, Jefferson's position appears more economically and politically ambitious. By 1791, the French colony of Saint Domingue held the title of the richest colony in the Caribbean and the world's leading producer of sugar. In addition, Saint Domingue consumed about sixteen percent of all of America's exports. Jefferson's personal opinions concerning revolution and trade on the island of Saint Domingue contradict the statements of his administration. Partisan politics manifested a stern voice within …

Effects Of Nutrients From The Water Column On The Growth Of Benthic Microalgae In Permeable Sediments, Brian P. Darrow

USF Tampa Graduate Theses and Dissertations

In some continental shelf sediments integrated benthic microalgal biomass is greater than the integrated phytoplankton biomass in the overlying water column. In addition, benthic microalgae may account for up to 10% of the primary production responsible for the coastal fishery yield of the eastern United States.

A three-dimensional model of the eastern Gulf of Mexico examines the effects of water-column nutrient sources on the growth of benthic microalgae. To parameterize the exchange of nutrients across the sediment/water interface in these permeable sediments, a non-local exchange submodel was constructed and tested within the framework of the model's grid.

Based on the …

Florida Red Tides: Public Perceptions Of Risk, Sara E. Allen

USF Tampa Graduate Theses and Dissertations

This research integrates the theoretical implications of risk perception, the social amplification of risk, and the role of place-specific contexts, in order to explore the various perceptions surrounding Florida red tides. Florida red tides are a naturally-occurring event, yet most scientists agree that they are increasing in frequency, duration, and severity. This has profound implication for public health, the local economy, and the biological community. While many of the negative impacts are not easily controllable at this time, some of the secondary impacts can be mitigated through individuals' responses. Unfortunately, public perceptions and consequent reactions to red tides have not …

Development Of A Scale To Measure Parenting In Hispanic Adolescents’ Families, Evelyn Marie Alvarez

USF Tampa Graduate Theses and Dissertations

The ultimate goal of this research was to provide a tool to adequately examine the relationship that parenting style has with Hispanic youths' academic and behavioral outcomes. A review of the literature reveals that the field is lacking an appropriate, culturally sensitive, paper-and-pencil measure of parenting of Hispanic adolescents with adolescents reporting on their parents' behavior. Current measures were not developed with Hispanic families in mind, but rather were evaluated for use with Hispanic populations after the development phase. Therefore, the current study sought to fill this gap in the research on parenting by constructing a measure of parenting that …

Thermochemical Treatment Of Tio2 Nanoparticles For Photocatalytic Applications, Mark Schmidt

USF Tampa Graduate Theses and Dissertations

Titanium Dioxide (TiO 2) has been considered an ideal photocatalyst due to

factors such as its photocatalytic properties, chemical stability, impact on the

environment and cost. However, its application has been primarily limited to

ultraviolet (UV) environments due to its high band gap (3.2 eV). This high band

gap limits the harvesting of photons to approximately 4% of sunlight radiation.

Research today is focused on lowering this gap by doping or coupling TiO 2 with

other semiconductors, transition metals and non-metal anions, thereby

expanding its effectiveness well into the visible range.

This thesis explores the effects of thermal and thermochemical …

Acoustic Classification Of Benthic Habitats In Tampa Bay, Shane C. Dunn

USF Tampa Graduate Theses and Dissertations

The need for assessment of benthic habitat characteristics may arise for many reasons. Such reasons may include but are not limited to, habitat mapping, environmental concerns and identification of submerged aquatic vegetation. Oftentimes, such endeavors employ the use of aerial photography, satellite imagery, diving transects and extensive sampling. Aerial photography and remote sensing techniques can be severely limited by water clarity and depth, whereas diver transects and extensive sampling can be time consuming and limited in spatial extent. Acoustic methods of seabed mapping, such as the acoustic sediment classification system QTC are not hampered by water clarity issues. The acoustic …

An Evaluation Of Movement Patterns And Effects Of Habitat Patch Size On The Demography Of The Florida Mouse (Podomys Floridanus), Irmgard Lukanik

USF Tampa Graduate Theses and Dissertations

Habitat degradation by humans has been the main reason for the decline in numbers of P. floridanus, the only mammal indigenous to the state of Florida, in the past century. The mouse inhabits what remains of scrub and sandhill associations, which are characterized by patches of sandy soils within a more mesic landscape. It has long been accepted that small populations are more prone to decline and extinction than are larger ones as a result of environmental fluctuations. I hypothesized that the demography of a population of P. floridanus would be affected by a restriction in numbers through habitat …

Geomorphology Of Submarine Spring West Of Fort Myers, Florida, Shihadah M. Saleem

USF Tampa Graduate Theses and Dissertations

In March of 2000, March of 2001, and April of 2002, multibeam bathymetry and backscatter data were collected, which revealed several low-temperature hydrothermal submarine springs in the Mudhole Submarine Springs (MHSS) area that were investigated by SCUBA divers. High-resolution multibeam sonar provides a precise way of defining the geomorphology of the seafloor. The bathymetry data were used to understand (1) vent geomorphology and how it varied from vent to vent; (2) spatial patterns of active vents compared to extinct vents and known land springs identified by Kohout (1977) and Breland (1980); and (3) potential correlations between geochemical and geomorphological characteristics …

The Use Of Microarrays In The Detection Of The Gene Expression Of Ribulose- 1,5- Bisphosphate Carboxylase/Oxygenase (Rubisco) In The Marine Environment, Kathryn Lafaye Bailey

USF Tampa Graduate Theses and Dissertations

The Calvin-Benson-Bassham (CBB) pathway is the primary pathway for the entry of inorganic carbon in the biosphere. Autotrophic organisms use this cycle to ultimately convert CO₂ into carbohydrates using a key enzyme known as ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO). The gene that encodes for the large subunit of RubisCO is rbcL and detection of its expression can be used to determine the autotrophic organisms present in the environment. Recently, microarrays have been used to study functional gene expression from environmental samples such as those obtained from sediments and soil. The purpose of this thesis is to combine microarray technology and rbcL …

Transendothelial Migration Of Metastatic Cancer Under The Influence Of Cigarette Smoke Condensate, Daniel Opp

USF Tampa Graduate Theses and Dissertations

Cigarette smoke's influence on cancer has primarily been a subject of epidemilogic and tumorigenic studies. There have been no proper investigations with interests focused on how cigarette smoke affects the cellular mechanics of metastasis. Gathering an understanding of how smoke influences metastatic invasion could be vital in regulating or possibly eliminatings cancer's ability to initiate new tumor growth sites. This project focuses on cigarette smoke's influence on cellular mechanics of endothelial cells, and the invasive potential of cancer against a fully active endothelium. It is already known that cigarette smoke has a carcinogenic effect, but it is hypothesized that the …

Alternative Targets For The Treatment Of Stroke, Craig T. Ajmo Jr.

USF Tampa Graduate Theses and Dissertations

Stroke is cerebrovascular injury that has been reported to be the third leading cause of death and the first leading cause of disability in the world (W. H.O. 2007). Currently, there is only one FDA approved treatment for stroke which is recombinant tissue plasminogen activator. This treatment has a narrow therapeutic window of three hours after ischemic stroke and can adversely cause the production of oxygen free radicals and intracranial hemorrhage. These limitations result in only 2-3% of all stroke victims as being candidates for this therapy as many patients do not arrive at the hospital in time to receive …
