Gallium Nitride Sensors For Hydrogen/Nitrogen And Hydrogen/Carbon Monoxide Gas Mixtures, Christopher Nicholas Monteparo

USF Tampa Graduate Theses and Dissertations

As hydrogen is increasingly used as an energy carrier, gas sensors that can operate at high temperatures and in harsh environments are needed for fuel cell, aerospace, and automotive applications. The high temperature Fischer-Tropsch process also uses mixtures of hydrogen and carbon monoxide to generate synthetic fuels from non-fossil precursors. As the Fischer-Tropsch process depends upon particular gas mixtures to generate various fuels, a sensor which can determine the proper ratio of reactants is needed. To this end, gallium nitride (GaN) has been used to fabricate a resistive gas sensor. GaN is a suitable semiconductor to be used in hydrogen …

Giving Birth In A Different Country: Bangladeshi Immigrant Women’S Childbirth Experiences In The U.S., Mst Khadija Mitu

USF Tampa Graduate Theses and Dissertations

Immigrant women often lack the social support and help from extended family and other social relationships, which is very significant during the pregnancy, delivery, and postnatal period. This research was conducted among Bangladeshi immigrant women living in the United States, in order to understand their experiences during pregnancy and childbirth: how they coped with the settings of a different country during that period, and how they felt about this situation. While there are several studies on immigrant women and maternal health issues in anthropology, to my knowledge, there have been none that focused specifically on the childbirth experiences of Bangladeshi …

Data Acquisition For Modeling And Visualization Of Vascular Tree, William Lafayette Mondy

USF Tampa Graduate Theses and Dissertations

Data can be acquired from tissue's vascular structure and used for modeling and visualization. To acquire data from a vascular tree, we make its structure available for the gathering of data by separating it from the structures of surrounding tissues, which includes the capillary structure. The capillary structure contains important information, but, because of its size, is the most difficult to acquire data from. In this work, we look at methods for contrasting the vascular structure from surrounding tissues, and focus on the use of corrosion casting for this procedure. We collected image data using micro-computer tomography (micro-CT) and converted …

In particular, YPAR provides young people with the opportunity to study social problems that affect themselves …

An Evaluation Of The Influence Of Case Method Instruction On The Reflective Thinking Of Msw Students, Marleen Milner

USF Tampa Graduate Theses and Dissertations

Social work practice requires that graduates be prepared to deal with complex, multifaceted problems which cannot be defined completely, do not have absolute, correct answers and can be approached from multiple perspectives. This study evaluated the influence of case-based instruction on MSW students' reflective judgment, an aspect of critical thinking associated with the ability to reason through ill-structured problems. (King, Wood, & Mines, 1990). The Reflective Judgment Model, which describes a developmental continuum based upon epistemic assumptions regarding the source and justification of knowledge claims, served as the theoretical framework for the assessment of reflective thinking in this mixed methods …

The Morphological Complexity Of Spelling, Ages 8 To 15 Years, Courtney R. Mossing

USF Tampa Graduate Theses and Dissertations

Learning to spell requires integration of phonological, orthographic, and morphological knowledge. Historically, spelling development has been characterized by linear stages in which children learn to use these knowledge bases in succession. A more recent view challenges the linearity of this approach and proposes that spelling development from the beginning is characterized by the simultaneous interaction of all three linguistic factors. Minimal research exists that qualitatively investigates the integration of these three factors, especially as noted in derivational morphology. The study's purpose was to investigate spelling accuracy and qualitatively analyze the morphological error patterns of typically developing children, ages 8-15 years, …

Teaching Social Studies In An Age Of Globalization: A Case Study Of Secondary Social Studies Teachers’ Participation In The Una-Usa’S Global Classrooms Curriculum Program, Kelly R. Miliziano

USF Tampa Graduate Theses and Dissertations

The researcher found few studies that explore decisions of social studies teachers as they plan what and how to teach their classes. Over a century, social studies educators have adapted and responded to political, social, and economic changes. From educating immigrants a century earlier to addressing contemporary cross-border issues, social studies educators inherit unique challenges in today's increasingly globalized world. In addition to these external forces, constraints are placed on teachers which prescribe what content must be included in an already crowded curriculum. This qualitative approach using a case study provides a better understanding of the influence a globally oriented …

Songs For Cripples, Michael Nelson

USF Tampa Graduate Theses and Dissertations

Ecis Assessment Of Cytotoxicity And Trans-Endothelial Migration Of Metastatic Cancer Cells, Daniel Opp

USF Tampa Graduate Theses and Dissertations

The investigations conducted within this dissertation centers around the use of electric cell-substrate impedance sensing (ECIS). This system is able to characterize in real-time analysis, the adhesion of cells to their substrate and neighboring cells. With this, valuable information can be gathered with in-vitro experiments regarding a tissue culture's response to physiological stimulation. This dissertation has taken advantage of ECIS' ability to analyze toxicology, barrier function, and cancer invasion on a tissue culture. With proper analysis modifications, trans-epethelial resistance (TER) can be used as a cytotoxicity assay with higher sensitivity than previously thought. In vitro assessment of cytotoxicity based on …

Living Behind Bars? An Investigation Of Gated Communities In New Tampa, Florida, Scott E. Nonnemaker

USF Tampa Graduate Theses and Dissertations

With protective gates and guard booths restricting access to their entrances, master-planned gated communities have become a dominant form of suburban development throughout much of the country. Many home builders, developers, and real estate companies promote gated communities as a developmental step towards the creation of a real-life utopia. However, many academics, like Karina Landman and Martin Schonteich (2002), argue that their existence simply marks a new chapter in the fragmentation and polarization of societies all across the world. This study used a mixed methods approach to analyze the demographic makeup of individuals living in gated communities in New Tampa, …

Devised Architecture: Revitalizing The Mundane, Jason Novisk

USF Tampa Graduate Theses and Dissertations

In today's society, we view new as good, a universal standpoint that has become so commonly accepted as true, that to question it would be absurd. While many new items are an upgrade over their predecessor, it is important to understand that used items still retain a high amount of value and efficacy. Our landscape is filled with the mundane, industrial elements that surround us, yet due to our familiarity with them they are pushed to the background of our consciousness. However their commonplace should not mask their true potential value. By using what is already there before us, we …

Particulate Carbon, Nitrogen And Phosphorus Stoichiometry Of South West Florida Waters, Susan Mary Murasko

USF Tampa Graduate Theses and Dissertations

The southwestern Florida shelf marine environment has often been characterized as oligotrophic, yet these waters can support large, high biomass, persistent phytoplankton blooms, including blooms of the toxin producing dinoflagellate Karenia brevis. Little is known regarding which major nutrient potentially limits primary production in these waters as both inorganic nitrogen and phosphorus concentrations are often near the limits of analytical detection and it is difficult to estimate what percentage of the dissolved organic pool is available for phytoplankton uptake. To assess the nutrient status of phytoplankton populations on the southwest Florida shelf, this project examines the particulate nutrient stoichiometry of …

Development And Investigation Of Novel Nanostructures And Complex Hydrides For Hydrogen Storage, Michael Ulrich Niemann

USF Tampa Graduate Theses and Dissertations

Over the past few years, the need for a clean and renewable fuel has sharply risen. This is due to increasing fossil fuel costs and the desire to limit or eliminate harmful by-products which are created during the burning of these fuels. Hydrogen is the most abundant element in the universe and can be used in either fuel cells or traditional internal combustion engines to produce energy with no harmful emissions. One of the main obstacles facing the implementation of a hydrogen economy is its storage. Classical methods of storage involve either high and unsafe pressures or liquid storage involving …

USF Tampa Graduate Theses and Dissertations

Prescriptions for effective display of quantitative information involving more than two variables are not available. To explore the effectiveness of retinal variables in facilitating the interpretation of information and decision making when used in conjunction, a study with 135 participants was conducted. The study involved the use of color shape, color value, and value shape as retinal variables in interactive displays that required participants to answer nine questions in three levels of complexity (identification of data points, analyses of local comparisons and global trends). Time-on-task scores and performance scores were measured. In addition, a View Clamp eye tracker system was …

Architectural Chastity Belts: The Window Motif As Instrument Of Discipline In Fifteenth-Century Italian Conduct Manuals And Art, Jennifer Megan Orendorf

USF Tampa Graduate Theses and Dissertations

As the Italian thirst for excellence and knowledge burgeoned throughout the Quattrocento, the genre of instructional literature responded accordingly to social demands. Offering advice on a wide range of experience from the quotidian to the extraordinary, from superstition to scientific, conduct manuals appealed to readers of all Italian social classes. Investigating the relationship between this body of literature and the lives of contemporary women, this paper will focus specifically on those manuals which prescribe behaviors for women, and will investigate the reception of these precepts and the extent in which these notions informed and transformed women's lives.

In order to …

This phenomenological qualitative research involved the use of semi-structured interviews with 16 nursing faculty from four Florida public universities, who were asked to describe their experiences transitioning from classroom to online teaching. Interview questions focused on their prior assumptions about online education, their preparation for online teaching, their current teaching methods, and the identification of information they would recommend as vital for successful online teaching. Participants were voluntary and selected by both criterion and network sampling. Interviews were …

Statistical Changes In Lakes In Urbanizing Watersheds And Lake Return Frequencies Adjusted For Trend And Initial Stage Utilizing Generalized Extreme Value Theory, Shayne Paynter

USF Tampa Graduate Theses and Dissertations

Many water resources throughout the world are demonstrating changes in historic water levels. Potential reasons for these changes include climate shifts, anthropogenic alterations or basin urbanization. The focus of this research was threefold: 1) to determine the extent of spatio-temporal changes in regional precipitation patterns 2) to determine the statistical changes that occur in lakes with urbanizing watersheds and 3) to develop accurate prediction of trends and lake level return frequencies. To investigate rainfall patterns regionally, appropriate distributions, either gamma or generalized extreme value (GEV), were fitted to variables at a number of rainfall gages utilizing maximum likelihood estimation. The …

The Concept Of Action And Responsibility In Heidegger’S Early Thought, Christian Hans Pedersen

USF Tampa Graduate Theses and Dissertations

In his early thought (which for our purposes will be considered to be roughly the time period from his first post World War I lecture course in 1919 to the publication of Being and Time in 1927), Heidegger offers a rich description of our practical engagement with the world. The aim of this project is to develop a Heideggerian conception of action from these early, concrete descriptions of the practical dimension of human life. The central feature of this Heideggerian conception of action is that action is understood as involving interdependent aspects of passivity and activity (or receptivity and spontaneity, …

This is a multi-method, multi-source, retrospective explanatory study of the implementation factors associated with program installation and partial implementation of an evidence-based violence prevention program, Second Step, in six elementary schools within a large urban school district. The goals of this study were to provide a better understanding of (a) the factors that support implementation of evidence-based programs in K-12 public schools, (b) the factors that constrain implementation, and (c) how developers and researchers might facilitate the application of research …

Prevalence And Influence On Quality Of Life Of Symptoms Caused By Inhaled Odors, Chemicals And Irritants: A Comparison Between Hispanics And Americans, Carmen Perez

USF Tampa Graduate Theses and Dissertations

Efforts to estimate the population prevalence of chemical sensitivities have been limited and have yielded different estimates of the prevalence of affected individuals. Researchers recognize that people differ in their biological susceptibility to environmental contaminants as well as the amount of contaminant to which they are potentially exposed. Lack of information on the population prevalence of people, who report sensitivity to a chemical or many chemicals, as well as variables associated, has been recognized in previous studies (Kreutzer et al., 1999). In a more recent report, Berg et al., in 2007 reported the prevalence and consequences related to inhalation of …

Classroom Discourse And Teacher Talk Influences On English Language Learner Students' Mathematics Experiences, Mariana M. Petkova

USF Tampa Graduate Theses and Dissertations

This study examined the features of the classroom discourse in eight Algebra I classes from two urban high schools with diverse student populations. In particular, by using the discursive analysis perspective, the type of communication between teachers and students was examined. The study investigated to what extent teachers' patterns of discourse change as a result of the number of ELLs present or their particular teaching experiences and ESOL endorsement. Furthermore, the impact of teachers' cultural and linguistic backgrounds upon ELLs' mathematics experiences was explored, particularly the teachers' patterns of discourse and adjustments to their teacher talk, or modifications of instructions …

Cultural Visualization Through Architecture, Fernando Pizarro

USF Tampa Graduate Theses and Dissertations

As an important part of our lives, stories help us to form both our personal identities and the identities of the social groups that make up our society. They facilitate us to be in contact with our beliefs, our feelings, our knowledge, our perception, and what is significant to us. Similarly, we understand those very things from the stories of others. These stories are obtained through different ways: family, friends, literature, poetry, religion, teachers, movies, art, and so on. Through these, our culture is born and sustained. There is no doubt that architecture is an important defining element of our …

An Explanatory Examination Of Relationships Between Measures Of School And Student Socioeconomic Status And Reading And Math Achievement Of Hispanic Limited English Proficient (Lep) High School Students, Osvaldo Piedra

USF Tampa Graduate Theses and Dissertations

Hispanics are the largest and fastest growing minority population in the U.S. requiring limited English proficiency services (Guglielmi, 2008). Many schools and school districts place heavy emphasis on high stakes testing. The No Child Left Behind (NCLB) Act of 2001 requires all children to have access to a fair, equal, and high-quality education. Many schools and school districts focus on individual students to show grade level performance for small populations such as limited English proficient (LEP) students. The purpose of this study was to examine the question, "What was the relationship between measures of school and student socioeconomic status, and …

Does Michelangelo's Poetic Veil Shroud A Secret Luther?, Edith Carolyn Phillips

USF Tampa Graduate Theses and Dissertations

The thesis poses a question derived from an unlikely nexus of two prominent figures of the Renaissance and the Reformation: the artist whose creative abilities ostensibly dominate the Vatican and religious art, juxtaposed with the rebel who splintered the dominance of Roman Catholicism. Michelangelo's program of artistic and religious reform in the second quarter of the sixteenth century strikes a chord similar to Martin Luther's theological perspectives set forth in the Reformation. Through the influence of the artist's friendship with the noblewoman, Vittoria Colonna, and subsequent involvement with an elite and cultured Italian reform group called the Spirituali, his later …

Biotopia: An Interdisciplinary Connection Between Ecology, Suburbia, And The City, Jessica Phillips

USF Tampa Graduate Theses and Dissertations

In an era when cities and towns are changing rapidly, public spaces are the key to reviving civic engagement. By re-introducing these public realms as ecological environments, we can re-structure the organic growth of civic tissue, re-define the city street into a park environment, and reveal the ecological landmarks that once beautified the landscape. These ecological landmarks will be used as corridors, nodes of circulation and storm water management to not only creates a regenerative landscape but to create a connection between ecology, suburbia and the city. The public realm in America has two roles: it is the dwelling place …

Effects Of Dialect Use On The Fast Mapping Skills Of African American School-Age Children, Jessica Pierre

USF Tampa Graduate Theses and Dissertations

Previous research has shown that African American children are prone to score lower on vocabulary tests when compared to their white peers (Champion et al., 2003; Qi et al., 2006; Restrepo et al., 2006; Thomas-Tate et al., 2006; Washington & Craig, 1992). The dialect spoken by these children may be affecting their performance. However, little is known about how dialect use interacts with word learning abilities. The current study continues a project initiated by Wyatt, Bahr, and Silliman (2007) which examined dialectal influences on the fast mapping of novel stimuli in preschool children. The participants in the current study were …

Mentorship Racial Composition And The Judgments Made By Individuals External To The Relationship, Laura F. Poteat

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to examine how the racial composition of a mentoring relationship influences three types of judgments made by individuals external to the relationship: (1) causal attributions formed to explain successful protégé performance; (2) evaluations of protégé career advancement potential; and (3) reward recommendations for the mentor and protégé. Additionally, the associations among causal attributions, evaluations of potential, and reward recommendations were investigated. A 2 (protégé race: white vs. black) x 2 (mentor race: white vs. black) factorial between-subjects design was used. Mentor and protégé races were manipulated within a written vignette. After reading the vignette, …
