Computational Discovery Of Phenotype Related Biochemical Processes For Engineering, Andrea M. Rocha

USF Tampa Graduate Theses and Dissertations

Application of bioengineering technologies for enhanced biological hydrogen production is a promising approach that may play a vital role in sustainable energy. Due to the ability of several naturally occurring microorganisms to generate hydrogen through varying metabolic processes, biological hydrogen has become an attractive alternative energy and fuel source.

One area of particular interest is the production of biological hydrogen in organically-rich engineered systems, such as those associated with waste treatment. Despite the potential for high energy yields, hydrogen yields generated by bacteria in waste systems are often limited due to a focus on microbial utilization of organic material towards …

Visual Search For Smoking Stimuli: Detection And Distraction, Jason A. Oliver

USF Tampa Graduate Theses and Dissertations

Extensive research has shown that the attentional systems of addicted individuals are biased towards drug-related stimuli, but despite several decades of effort these results have frequently been inconsistent. Though commonly believed to result from addiction and dependence, cognitive research would suggest that frequent exposure to drug-related stimuli could affect the attentional processing of drug-related cues even if no actual drug use occurs. The present investigation examined attentional bias for smoking cues using a novel visual search paradigm amongst smokers currently in nicotine withdrawal and fully satiated smokers, as well as a non-smoker control group. Variables related to smoking behavior, as …

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, …

To See And Be Seen: Exploring Layers Of Instructional Leadership And Supervision In The Enactment Of A District-Wide Teacher Evaluation Reform, Jenifer E. Neale

USF Tampa Graduate Theses and Dissertations

This dissertation analyzes instructional leadership and evaluation protocols from a large, diverse district in the Southeastern United States in order to investigate layers of accountability and tensions created when principals are asked to fill the dual roles of both instructional leader and supervisor in a newly implemented teacher evaluation system reform. For this dissertation I investigate the role of the principal as a colleague and mentor and compare this with the role of the principal as supervisor and evaluator in hierarchical systems. I include the role of the peer evaluator, a new position, in my analysis. Critical discourse analysis is …

Nearer, My Farm, To Thee: A Spatial Analysis Of African American Settlement Patterns In Hillsborough County, Florida, Matthew Andrew O'Brien

USF Tampa Graduate Theses and Dissertations

Geographic Information Systems (GIS) have demonstrated their utility in predictively modeling the location of archaeological sites, and providing a framework for cataloging sites eligible for heritage management status. The intent of this GIS-based study is to begin to create a geohistorically organized database of information culled from historic documents and archaeological excavation. In this case study of postbellum land tenure in Hillsborough County, Florida, a GIS-based approach is used to demonstrate the impacts of federal and state land ownership policy decisions during the Reconstruction Era and beyond. GIS data are also used to reveal information about how people use their …

Multivariate Anti-Inflammatory Approaches To Rescue Neurogenesis And Cognitive Function In Aged Animals, Sandra Antonieta Acosta

USF Tampa Graduate Theses and Dissertations

Studies have shown that there is a strong correlation between aging and neurodegenerative diseases. Aging is considered the number one risk factor to develop neuropathologies such as memory loss, senile dementia, Alzheimer's disease (AD), and Parkinson's disease. Neurodegenerative diseases tend to start during adulthood, and aggravate over time, making them difficult to prevent and to treat. In the Unites States, demographic studies by U.S. Bureau of the Census have determined that our aging population of >65 years is expected to increase from the present 35 million to 78 million in 2030. This would result, not only to an increase of …

Impact Of A Wellness Clinic Visit On Cardiovascular Risk Biomarkers In Employees Of A Va Medical Center, Margaret Asomaning

Children Who Die Of Abuse: An Examination Of The Effects Of Perpetrator Characteristics On Fatal Versus Non-Fatal Child Abuse, Donald L. Dixon

USF Tampa Graduate Theses and Dissertations

Approximately 2000 children die annually in the United States from abuse and neglect, but the interplay of factors such as perpetrator characteristics and family composition which place these children at risk have not been wellestablished. The review of the literature focuses on the correlation between child deaths resulting from abuse and perpetrator characteristics most associated with these deaths. Characteristics such as the perpetrator’s age, race/ethnicity, gender, alcohol and substance use/abuse and/or sale, and prior history of abuse are among those examined. Additionally, these factors are examined within ecological and risk and protective factor theoretical frameworks. It is argued that further …

Making Meaning With "Readers" And "Texts": A Narrative Inquiry Into Two Beginning English Teachers' Meaning Making From Classroom Events, Christi Underwood Edge

USF Tampa Graduate Theses and Dissertations

Situated in a transactional paradigm, connections between the constructs of meaning and experience in both teacher education and reading in English education guided my construction of a theoretical framework called Classroom Literacy. This framework extends Rosenblatt's Transactional Theory of Reading (1978, 1994, 2005), broadens the concept of text to include the verbal and non-verbal communicative signs related to the context of the classroom, and positions teachers as "readers" of their classrooms as texts. The Classroom Literacy theoretical framework guided my thinking as I re-conceptualized three persistent problems in learning to teach (Hammerness, Darling-Hammond, Bransford, Berliner, Cochran-Smith, McDonald, & Zeichner, 2005)--an …
