Theology, Spirituality, And The Academic Study Of Religion In Public Universities, Don Saunders

USF Tampa Graduate Theses and Dissertations

This thesis examines whether the secular institutions of American higher education should address students questions of meaning, purpose, wisdom, and human destiny. That is, it investigates the place of the normative analysis of religious experience and behavior within the public university. I use the work of Ninian Smart, Russell T. McCutcheon and Ivan Strenski to illustrate the case against the inclusion of theology and spirituality in the academic study of religion. In their view, theology is at best an artifact, like ritual or religious art and not an academic discipline. Conversely, I use the work of Paul Tillich, John Dunne, …

USF Tampa Graduate Theses and Dissertations

Molecular tools, such as sequencing of the mitochondrial DNA Control Region (CR) and genotyping of highly variable nuclear microsatellites were applied to survey the genetic diversity, population structure and phylogeography of three shark species: the whale shark, Rhincodon typus; the bull shark, Carcharhinus leucas; and the nurse shark, Ginglymostoma cirratum. The highly migratory and pelagic whale shark exhibited the largest length variation yet reported for an elasmobranch CR (1143–1332 bp), and high haplotype (h = 0.974 ± 0.008) and nucleotide diversities(π = 0.011 ± 0.006). No geographical clustering of lineages was observed and the most common …

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 …

USF Tampa Graduate Theses and Dissertations

Nutrient distribution correlates with discharge of freshwater from Franklin Lock and Dam structure (S-79) by delivery into the Caloosahatchee Estuary (CE) and out of this area, including the surrounding San Carlos Bay (SCB) and adjacent West Florida Shelf. This study analyzed the temporal and spatial distribution of nutrients along the CE waterway and illustrates the effects high freshwater discharge from S-79 has on the coastal and offshore environments, providing a potential source of nutrient input. This study consisted of a 7-station transect monitored biweekly from April 2005 thru August 2006 for nutrients, dissolved oxygen, chlorophyll a, and salinity, along …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

With the increasing advancements in the digital technology, future wireless systems are promising to support higher data rates, higher mobile speeds, and wider coverage areas, among other features. While further technological developments allow systems to support higher computational complexity, lower power consumption, and employ larger memory units, other resources remain limited. One such resource, which is of great importance to wireless systems, is the available spectrum for radio communications. To be able to support high data rate wireless applications, there is a need for larger bandwidths in the spectrum. Since the spectrum cannot be expanded, studies have been concerned with …

Performance Of Rapid Tooling Molds For Thermoformed Sockets, Jairo R. Chimento

USF Tampa Graduate Theses and Dissertations

Traditional prosthetic socket fabrication is a laborious and time consuming process that involves physical measurements, plaster wrapping of the stump, plaster casting for positive mold preparation, and a thermoforming process. During the mold preparation stage, significant modifications are performed subjectively based on the prosthetist's experience to transmit an optimum load to the residual limb through the socket. Rapid Prototyping techniques have advanced rapidly during the recent decades emerging as a computer aided socket design alternative which promises a potential reduction in the fabrication time, and a more systematic design approach. In addition, 3-D scanning provides accurate and fast virtual replica …

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 …

Work-Family Conflict, Eating Behaviors, And The Role Of Coping, Ashley G. Walvoord

USF Tampa Graduate Theses and Dissertations

There were two primary aims of the present study. The first aim was to examine the relationships between work-interference-with-family (WIF) and specific eating behaviors (eating vegetables, fruits, snack foods) reported by employed mothers, as it relates to health criteria such as BMI. Related to this first aim, household coping strategies were proposed as playing a significant role in the relationship between WIF and eating behaviors. The second aim was to investigate the crossover of WIF to specific child eating behaviors via mother feeding practices or mother eating behaviors.

Self-report and other-report survey data were collected from working mothers and their …

Cooper-Hewitt Museum Of Design And Technology (C-Hmd+T): Biomimetic Architecture As Part Of Nature, Isabel Marisa Corsino Carro

USF Tampa Graduate Theses and Dissertations

If architects are to create a sustainable world, one in which we are accountable to the needs of all future generations and living creatures, we must recognize that our present form of designing buildings is deeply flawed. Being the number one cause of emission gases, building design needs to be revolutionized to be able to surpass such climatic changes and finally harmonize with nature. To create a sustainable future and solve the global warming crisis, architects need to incorporate nature within design through the process known as biomimicry. Janine Benyus, the author of Biomimicry: Innovation Inspired by Nature, stressed how …

Techniques For Vlsi Circuit Optimization Considering Process Variations, Mahalingam Venkataraman

USF Tampa Graduate Theses and Dissertations

Technology scaling has increased the transistor's susceptibility to process variations in nanometer very large scale integrated (VLSI) circuits. The effects of such variations are having a huge impact on performance and hence the timing yield of the integrated circuits. The circuit optimization objectives namely power, area, and delay are highly correlated and conflicting in nature. The inception of variations in process parameters have made their relationship intricate and more difficult to optimize. Traditional deterministic methods ignoring variation effects negatively impacts timing yield. A pessimistic worst case consideration of variations, on the other hand, can lead to severe over design. In …

The Participation Of Ngos In Healthcare: The Case Of Pediatric Cancer Treatment In Argentina, Cecilia Vindrola Padros

USF Tampa Graduate Theses and Dissertations

The deterioration of the Argentine public health system has lead to an increase in non-governmental involvement in the provision of health services. The emerging relationship between these sectors is filled with tensions, contradictions, and negotiations, reflecting the historical trajectory of non-governmental organizations (NGOs) and the transformations of the public health system. These problems are specifically evident in programs that focus on pediatric oncology treatment due to the fact that ideas about childhood, chronic disease, and mortality construct an unusual collaborative framework between governmental and non-governmental healthcare professionals. Pediatric cancer contradicts traditional notions of childhood; it points out the ambivalences associated …

Effects Of Diluent Addition And Metal Support Interactions In Heterogeneous Catalysis: Sic/Vpo Catalysts For Maleic Anhydride Production And Co/Silica Supported Catalysts For Fts, Ala'a Hamed Kababji

USF Tampa Graduate Theses and Dissertations

This work begins with an introduction to catalysis focusing on heterogeneous systems and surface science phenomena. A study on the partial oxidation reaction of n-butane to maleic anhydride (MA) is presented in the first part. MA supplies are barely adequate for market requirements due to continued strong demand. Only slight improvement in catalytic performance would be welcome in the industrial community. The vanadium phosphorus oxide (VPO) catalyst was used in this work. The reaction is highly exothermic and the need to properly support the catalyst, not only for good dispersion but adequate heat dissipation is of crucial importance. For this, …

Semantic And Phonological Priming Effects On N400 Activation In People Who Stutter, Jessica Lauren Huffman

USF Tampa Graduate Theses and Dissertations

To date, research on mechanistic aspects of fluency disorders has focused heavily on motor contributions to stuttering. Only recently have researchers begun to explore psycholinguistic contributions to stuttering. Psycholinguistic planning for speech heavily involves the activation and processing of lexical information. We used a neuroscience approach to compare word activation in mental lexicon while completing a picture naming task in people who stutter (PWS) versus fluent individuals (PWNS).

Twenty-eight individuals ranging in age from 19 - 52 years old participated in a picture-word priming task adopted from Jescheniak et al. (2002). Electroencephalogram (EEG) was recorded while participants saw black and …

Developing Feminist Activist Pedagogy: A Case Study Approach In The Women's Studies Department At The University Of South Florida, Stacy Tessier

USF Tampa Graduate Theses and Dissertations

In this thesis, I examine the relationship between activism and the two introductory-level Women's Studies classes, Introduction to Women's Studies and Issues in Feminism, and the social justice mission of the Women's Studies department. These two classes are the pillars for the program and are often the first classes that draw students into the program. I propose that the Women's Studies department does promote social justice through the curriculum and there are ways that the department could do more to facilitate activism in the classroom and beyond the classroom.

The Women's Studies department at the University of South Florida is …

The Characterization And Interpretation Of The Spectral Properties Of Karenia Brevis Through Multiwavelength Spectroscopy, Adam H. Spear

USF Tampa Graduate Theses and Dissertations

Optical research has shown that Karenia brevis has distinct spectral characteristics, yet most studies have focused exclusively on absorption and chemical properties, ignoring the size, shape, internal structure, and orientation, and their effect on scattering properties. The application of a new spectral interpretation model to K. brevis is shown to provide characterization of unique spectral information, not previously reported, through the use of scattering and absorption properties. The spectroscopy models are based on light scattering and absorption theories, and the approximation of the frequency-dependent optical properties of the basic constituents of living organisms. The model uses the process of mathematically …
