African American Perceptions Of The Florida Comprehensive Assessment Test (Fcat) And High School Graduation, Maressa L. Dixon

USF Tampa Graduate Theses and Dissertations

While there is ample research theorizing reasons for so-called "achievement gaps" between African American and White students on standardized tests, few studies explore African Americans' perceptions of the impact these tests have on overall education. Through interviews with six current students attending Hillsborough County public high schools, one recent graduate of a Hillsborough County high school, and two parents of students in Hillsborough County public schools, this research study probes participants' perceptions of the impact of the Florida Comprehensive Assessment Test (FCAT) on their high school experiences. All participants in the study identified as African American or Black. Through archival …

Germania-Based Sol-Gel Organic-Inorganic Hybrid Coatings For Capillary Microextraction, Li Fang

USF Tampa Graduate Theses and Dissertations

For the first time, germania-based hybrid organic-inorganic sol-gel materials were developed for analytical sample preparation and chromatographic separation. Being an isostructural analog of silica (SiO₂), germania (GeO₂) is compatible with silica network. This structural similarity, which is reflected by the relative positions of germanium and silicon in the periodic table, stimulated our investigation on the development of germania-based sol-gel hybrid organic-inorganic coatings for analytical applications.

Sol-gel sorbents and stationary phases reported to date are predominantly silica-based. Poor pH stability of silica-based materials is a major drawback. In this work, this problem was addressed through development of …

A Vindication Of The Rights Of Woman: A Reflection Of The Tension Between Conformity And Rebellion In The Life And Times Of Mary Wollstonecraft, Ann Sofia-Rothschild

USF Tampa Graduate Theses and Dissertations

In this thesis I examine A Vindication of the Rights of Woman (1792) by Mary Wollstonecraft and how it reflects the tension between conformity and rebellion that is an inherent component in the life of its author and therefore is a fundamental element of this treatise. In this paper I discuss how the personal struggles of Mary Wollstonecraft, as a woman living in a patriarchal society, influenced her perspective and moved her to address her concerns for her "fellow creatures." This treatise pushed the boundaries of conventional thinking, but it was also written in traditional terms in an effort to …

Broadening The Spectrum: The Religious Dimensions Of The Rainbow Gatherings, Seth M. Walker

USF Tampa Graduate Theses and Dissertations

The purpose of this thesis is to specifically address the religious dimensions of the Rainbow Gatherings. The fundamental question directing this analysis is: "Are the Rainbow Gatherings religious in character?" This thesis specifically asks whether or not the Rainbow Gatherings satisfy certain identifiable features of religion, and if doing so, do they qualify as a form of religion? I engage this question by analyzing the Rainbow Gatherings in terms of two particular definitions of religion: Clifford Geertz's "functional" definition and Bryan R. Wilson's "substantive" definition. This allows me to analyze the Rainbow Gatherings from the perspective of the two major …

Testing The Plausibility Of A Series Of Causal Minor Cyberloafing Models, Kevin Askew

USF Tampa Graduate Theses and Dissertations

Cyberloafing is the nonsanctioned recreational use of the computers/internet during work hours. Although research is increasing, the processes related to cyberloafing are not well understood. In the current studies, I developed, tested, and evaluated a series of causal minor-cyberloafing models. In Study 1, I empirically compared four minor-cyberloafing taxonomies and selected two of these models as my working taxonomies for minor cyberloafing. In Study 2, I tested and evaluated eight causal minor-cyberloafing models using structural equation modeling techniques and various model-data fit indices. Results of Study 2 indicated that the models were not plausible, bringing into question the value of …

Asynchronous Cellular Automata - Special Networks Local Slowdown Produces Global Speedup, Arash Khani Ardestani

USF Tampa Graduate Theses and Dissertations

Information processing in living tissues is dramatically different from what we see in common man-made computer. The data and processing is distributed into the activity of cells which communicate only with neighboring cells. There is no clock for the global synchronization of cellular activities. There is not even one bit of central memory for globally shared data. The communication network between cells is highly irregular and may change without changing the outcome of the computation. A simple network of automata is introduced and analyzed to represent a mathematical model of special group of cells in an imaginary tissue sample. The …

New Port Richey: Myth And History Of A City Built On Enchantment, Adam J. Carozza

USF Tampa Graduate Theses and Dissertations

This thesis aims to discover, understand and appreciate the history of New Port Richey. New Port Richey's growth was affected by many of the same social changes taking place all over Florida, most notably the coming of the railroad, the popularity of the automobile, and the land boom of the 1920s. Post-World War II prosperity, pest control, air conditioning, and interstate highways attracted people to this city nicknamed the "Gateway to Tropical Florida." Unique to this area was the Legend of Chasco, an invented tradition to draw tourists and new residents to the area, and the beautiful Pithlachascotee River meandering …

Mitigating Escalation Of Commitment: An Investigation Of The Effects Of Priming And Decision-Making Setting In Capital Project Continuation Decisions, Ann C. Dzuranin

USF Tampa Graduate Theses and Dissertations

This research examines escalation of commitment in capital investment decisions and the extent to which it can be mitigated using a cognitive prime. Specifically, I examine the use of a cognitive prime as a way to mitigate escalation in three decision-making settings: (1) individual, (2) face-to-face team, and (3) computer-mediated team. Continued investment in failing projects is costly for firms. The use of a cognitive prime to reduce escalation would provide a low cost way to mitigate escalation. In this study, participants are primed to think about sunk costs. The expectation is that priming individuals to think about sunk costs …

Christoffel Function Asymptotics And Universality For Szegő Weights In The Complex Plane, Elliot M. Findley

USF Tampa Graduate Theses and Dissertations

In 1991, A. Máté precisely calculated the first-order asymptotic behavior of the sequence of Christoffel functions associated with Szego measures on the unit circle. Our principal goal is the abstraction of his result in two directions: We compute the translated asymptotics, lim_n λ_n(µ, x + a/n), and obtain, as a corollary, a universality limit for the fairly broad class of Szego weights. Finally, we prove Máté’s result for measures supported on smooth curves in the plane. Our proof of the latter derives, in part, from a precise estimate of certain weighted means of the Faber polynomials associated …

Various forms of media penetrate our lives daily. Hip hop music has gained universal appeal and widespread success that permeates barriers of race, class, gender, age, and nationality. It is important for social service workers, parents, educators and other adults who interact with youth to understand the roles hip hop music and culture can play in the identities of those who are listening. In this study I conducted 12 open-ended interviews with adolescent hip hop fans about their music. The research presented in this thesis suggests that adolescent hip hop fans are making interpretations from the media and applying them …

N-Acyltyramines As Substrates For Tyrosinase: Enzymatic Lag And Dopamine Precursor, Jacob A. Shafer

USF Tampa Graduate Theses and Dissertations

Tyrosinase is a widespread, highly studied and important enzyme involved in processes ranging from the browning of mushrooms to roles in mammalian cancer. The enzyme suffers from a noticeable lag phase while the enzyme generates all necessary cofactors from available substrates. There have not been significant studies of the effect on lag from moving through a family of substituted substrates. This thesis reports the results of one such study using a family of N-acyltyramines.

The selection of N-acyltyramines was ideal because the substrates in this reaction may be related to synthesis of N-acyldopamines, which serve many important …

Tephra Transport, Sedimentation And Hazards, Alain C. M Volentik

USF Tampa Graduate Theses and Dissertations

Tephra deposits are one of the possible outcomes of explosive volcanic eruptions and are the result of vertical settling of volcanic particles that have been expelled from the volcanic vent into the atmosphere, following magma fragmentation within the volcanic conduit. Tephra fallout represents the main volcanic hazard to populated areas and critical facilities. Therefore, it is crucial to better understand processes that lead to tephra transport, sedimentation and hazards.

In this study, and based on detailed mapping and sampling of the tephra deposit of the 2450 BP Plinian eruption of Pululagua volcano (Ecuador), I investigate tephra deposits through a variety …

Reducing Sediment And Bacterial Contamination In Water Using Mucilage Extracted From The Opuntia Ficus-Indica Cactus, Audrey Lynn Buttice

USF Tampa Graduate Theses and Dissertations

Throughout the past decade an increased amount of attention has been drawn to the water contamination problems that affect the world. As a result, a variety of purification methods targeted at communities in developing countries have surfaced and, although all have contributed to the effort of improving water quality, few have been accepted and sustained for long term usage. Case studies indicate that the most beneficial methods are those which use indigenous resources, as they are both abundant and readily accepted by the communities. In an attempt to make a contribution to the search for water purification methods that can …

Characterization Of Conductive Polycarbonate Films, Selma Hokenek

USF Tampa Graduate Theses and Dissertations

Transparency and conductivity are highly desirable qualities in materials for modern gas sensors. Polymer gas sensors have been developed in which the polymer acts as a solid electrolyte. However, these types of sensors are opaque, which limits their potential for integration with dichromatic materials. The development of a sensor integrating conductive polymer films and dichromatic materials requires the implementation of a transparent conductive polymer film. The potential of iodine-doped bisphenol-a polycarbonate films containing bis(ethylenedioxy)-tetrathiafulvalene (BEDO-TTF) dye for sensor applications will be tested through characterization of the films at various stages of their fabrication using Atomic Force Microscopy (AFM), Transmission Electron …

Two Methodologies In Pursuit Of The Elucidation Of Copper (Ii)—Centered Bioinorganic Chemistry, William John Wagner

USF Tampa Graduate Theses and Dissertations

Copper is a widely distributed transition metal in the earth's crust and has been adopted in a variety of biological systems. In many ways the biochemical usefulness of copper stems from its positive redox potential. This positive redox potential allows copper to assist in the movement of electrons. Copper ions can be found in natural systems as either Cu^I, Cu^II or Cu^III in part due to this redox potential. While Cu^II -centered biochemistry has been studied for years, mechanistic details in certain Cu^II -centered redox reactions remain unresolved. This study presents two methodologies for …

Constructions Of Narrative Identities Of Women Political Candidates, Amy E. Daniels

USF Tampa Graduate Theses and Dissertations

I evaluate the ways in which newspaper articles constructed the gendered cultural and personal narratives of a woman Presidential and a woman Vice-Presidential candidate during the 2008 Presidential Election season. Drawing upon West and Zimmerman's "Doing Gender" (1987) that explains gender is performed constantly throughout life, I assess the stories told about each candidate and the way she performed gender. There are two different types of stories created. The first is a personal narrative which tells the story of each individual candidate, Hillary Clinton and Sarah Palin. The second is a cultural narrative which tells the story of a dis-embodied …

Meltwater And Abrupt Climate Change During The Last Deglaciation: A Gulf Of Mexico Perspective, Clare C. Williams

USF Tampa Graduate Theses and Dissertations

During the last deglaciation, Greenland ice core records exhibit multiple, high frequency climate events including the Oldest Dryas, Bølling-Allerød and Younger Dryas, which may be linked to meltwater routing of the Laurentide Ice Sheet (LIS). Previous studies show episodic meltwater input, via the Mississippi River to the Gulf of Mexico (GOM) several thousand years before the onset of the Younger Dryas until ~13.0 kcal (thousand calendar) yrs, when meltwater may have switched to an eastern spillway, reducing thermohaline circulation (THC). Data from laminated Orca Basin in the GOM, constrained by 34 Accelerator Mass Spectrometry (AMS) ¹⁴C dates, provide the …

Aggression And Its Consequences In Nursing: A More Complete Story By Adding Its Social Context, Liu-Qin Yang

USF Tampa Graduate Theses and Dissertations

Using a 471-case nursing sample, the current study examined the direct and indirect relationships between workplace aggression (including physical and psychological) against nurses and their health and safety consequences. Specifically, physical and psychological aggression nurses experienced were related to their job dissatisfaction, turnover intention, physical symptoms, injuries and exposure to contagious disease directly and/or indirectly through their emotional strain (irritation, anxiety, and depression). In addition, my findings demonstrated that stronger violence prevention climate (i.e., good prevention practices/response and low pressure for unsafe practices) was related to less frequent violence and psychological aggression incidents nurses experienced. Also, my results indicated significant …

The Quasi-Uniformity Condition And Three-Dimensional Geometry Representation As It Applies To The Reproducing Kernel Element Method, Nathaniel O. Collier

USF Tampa Graduate Theses and Dissertations

The Reproducing Kernel Element Method (RKEM) is a hybrid between finite elements and meshfree methods that provides shape functions of arbitrary order and continuity yet retains the Kronecker-delta property. To achieve these properties, the underlying mesh must meet certain regularity constraints, unique to RKEM. The aim of this dissertation is to develop a precise definition of these constraints, and a general algorithm for assessing a mesh is developed. This check is a critical step in the use of RKEM in any application.

The general checking algorithm is made more specific to apply to two-dimensional triangular meshes with circular supports and …

Are All Good Soldiers Created Equal? Examining The "Why" That Underlies Organizational Citizenship Behavior: The Development Of An Ocb Motives Scale, Anna Lissa Tolentino

USF Tampa Graduate Theses and Dissertations

Traditionally, organizational citizenship behaviors (OCBs) have been conceptualized within a social exchange framework, implying that individuals perform citizenship behaviors in response to fair treatment by the organization (Zellars & Tepper, 2003). In accordance with this social exchange framework, researchers have identified a number of OCB antecedents, like perceived organizational support (Moorman, Blakely, & Niehoff, 1998; Settoon, Bennet, & Liden, 1996), job satisfaction, organizational commitment, organizational justice (LePine, Erez, & Johnson, 2002; Organ & Ryan, 1995), and leader-member exchange (Connell, 2005; Settoon, Bennett, & Liden, 1996; Wayne & Greene, 1993). Recently, however, research has shifted from viewing OCB as a reactionary …
