An Evaluation Of Conduit Conceptualizations And Model Performance, Melissa Estelle Hill

USF Tampa Graduate Theses and Dissertations

The karst research community has known that traditional numerical groundwater flow codes ignore the non-Darcian, dual-permeability components of flow that can occur in karst aquifers. In this study, the potential limitations of using such tools are quantified by evaluating the relative performances of 3 groundwater flow models at a test-site near Weeki Wachee, Florida, in the dual-permeability Upper Floridan aquifer. MODFLOW-2005 and MODFLOW-2005 Conduit Flow Process (CFP), a Darcian/non-Darcian, dual-permeability groundwater flow code recently developed by the U.S. Geological Survey, are used in this study.

Movement And Distribution Of Juvenile Bull Sharks, Carcharhinus Leucas, In Response To Water Quality And Quantity Modifications In A Florida Nursery, Lori A. Ortega

USF Tampa Graduate Theses and Dissertations

Movement, distribution, and habitat use of juvenile bull sharks were examined in two studies using manual and passive acoustic telemetry. Research was conducted in the Caloosahatchee River, which serves as nursery habitat for this species, and is highly impacted due to anthropogenic alterations in water quality and quantity via dams and locks. Manual tracking yielded fine-scale results for eight individuals on home range size, rate of movement, swimming depth, linearity, direction of travel, tidal influence, diel pattern, as well as correlation with environmental variables. Changes in salinity, temperature, dissolved oxygen, turbidity, and pH played a role on the distribution of …

Heat Fluxes In Tampa Bay, Florida, Kristin L. Sopkin

USF Tampa Graduate Theses and Dissertations

The Meyers et al. (2007) Tampa Bay Model produces water level and three-dimensional current and salinity fields for Tampa Bay. It is capable of computing temperature but is presently run without active thermodynamics. Variations in water temperature are driven by heat exchange at the water-atmosphere boundary and advective heat flux at the mouth of the bay. The net heat exchange surface boundary condition is required for computations of three-dimensional temperature fields. Components of the surface heat budget were measured or derived at an observational tower in Middle Tampa Bay. Net heat exchange at the surface of Tampa Bay was computed …

Metropolitan Community Church: A Perfectly Queer Reading Of The Bible, Matthew D. Stewart

USF Tampa Graduate Theses and Dissertations

This thesis examines the hermeneutical strategies that Metropolitan Community Church (MCC) has employed in interpreting the Bible. As a new religious movement (NRM) with an outreach to gay, lesbian, bisexual, and transgendered individuals MCC interprets the text in light of its membership. The interpretive strategies and methodologies employed are in keeping with other denominations in the Christian tradition. This provides a possible avenue by which MCC can be classified within the Christian tradition.

The interpretation of the biblical text is given in light of the gay people who compose MCC's membership. Gays and lesbians have experienced social and religious stress. …

The Role Of Rala And Ralb In Cancer, Samuel C. Falsetti

USF Tampa Graduate Theses and Dissertations

Ras genes are frequently mutated in human cancers and present compelling targets for therapeutic intervention. While previous attempts to directly inhibit oncogenic Ras function have largely been unsuccessful use of targeted agents to inhibit the three primary oncogenic pathways activated by mutated Ras: RalGEF-Ral, PI3K-Akt and Raf- MEK-Erk, is an area of intense investigation. Here, we describe the ability of a novel pharmacological inhibitor of geranylgeranyltransferase I, GGTI-2417, to inhibit Ral prenylation and localization. We further used a Ral rescue system to selectively preserve RalA and RalB function and localization during GGTI-2417 treatment and determine the precise roles for inhibition …

An Experimental Analysis Of The Influence Of Corporate Social Responsibility Initiatives On Beliefs, Attitudes And Behavioral Intentions Within The Context Of Corporate, Ashlea Hudak

USF Tampa Graduate Theses and Dissertations

Recently, the use of corporate social responsibility initiatives has grown in popularity and prominence among organizations as research increasingly suggests that these initiatives positively impact the corporation's bottom line. This study contributes to theory driven research in strategic communications by using an experimental design to test the influence of six distinct corporate social responsibility initiatives, as identified by Kotler and Lee (2005), on the beliefs, attitudes, and behavioral intention of message receivers, using Fishbein and Ajzen's (1975, 2005) theory of reasoned action as a theoretical framework. According to Fishbein and Ajzen (1975), attitudes about an object are the result of …

Micro-Autoradiographic Fusion Tomography, James Merker

USF Tampa Graduate Theses and Dissertations

Two-dimensional (2-D) micro-autoradiography is typically used to identify the location of a radio-labeled ligand bound to a cellular target in tissue sections. Data, such as a histological image, combined with the autoradiographic data provide a spatial relationship of the radiolabel to cellular structures. However, the disadvantage of 2-D imaging is that it only provides a local distribution of the radiolabel within a tissue slice, and not a volumetric regional distribution in the structure of interest. The development of 3-D autoradiographic/histological visualizations would provide important information not otherwise apparent, such as the ability to visualize the distribution of the labeled agents …

¿Femenino O Feminista? Mensajes Para El Presente De Tres Escritoras Hispanas Del Siglo Xix, Beatriz Muller-Marqués

USF Tampa Graduate Theses and Dissertations

This thesis is a comparative study of Spanish and Latin-American women writers of the 19^th century. This work shows how these writers, even though distanced by geographical and/or generational gaps, as well as cultural differences, share, not only the Spanish language but also common interests, themes and discursive characteristics. The investigation focuses on the work of three renowned writers: Cecilia Böhl de Faber from Spain, and Gertrudis Gómez de Avellaneda and Clorinda Matto de Turner, from Latin-America. The three of them revolutionized in different ways the feminine perception in the nineteenth century.

USF Tampa Graduate Theses and Dissertations

In my thesis I endeavor to examine the influence and impact of memory -the mental and psychological processes of recollection-on the writings of three Cuban authors of the twentieth century. I have chosen José Lezama Lima, Guillermo Cabrera Infante, and Eliseo Diego because of their particularly vast and evocative literatures about the city: la Ciudad de La Habana. One of the main objectives of this work is to suggest the cultural predisposition of a twentieth century Cuban Literature that is consequential on its authors' recollections and reminiscences about the city. But, does this mnemonic-literary tendency truly exist in contemporary …

Impact Of West Nile Virus On The Natural History Of St. Louis Encephalitis Virus In Florida, Christy L. Ottendorfer

USF Tampa Graduate Theses and Dissertations

The emergence of West Nile virus (WNV) has raised important questions about the capacity of the public health infrastructure to implement surveillance and control programs for WNV and other emerging or re-emerging arboviruses in the United States. Florida's mild climate supports year round enzootic transmission of WNV, St. Louis encephalitis virus (SLEV), and Eastern Equine Encephalitis virus (EEEV). It is unknown what effect the establishment of WNV (in 2001) will have on SLEV transmission in Florida, where these closely related flaviviruses share amplifying hosts, habitats, and vectors.

An Arbovirus Isolation Network was formed to obtain and characterize arbovirus strains collected …

The Influence Of Ph On Nucleation, Solubility And Structure Of Lysozyme Protein Crystals, Marc C. Apgar

USF Tampa Graduate Theses and Dissertations

X-ray diffraction from protein crystals remains the most reliable way to determine the molecular structure of proteins, and how this structure relates to biological function. However, we still lack the ability to predict solution conditions that support the nucleation and growth of high-quality protein crystals for X-ray diffraction studies. The overall goal of this thesis is two-fold: (a) determine the nucleation behavior and solubilities for lysozyme crystals with two distinct crystal structures (orthorhombic vs. tetragonal) and (b) investigate whether these changes in crystal habit and crystal solubility correlate with any discontinuities in the liquid-liquid phase boundary of lysozyme that occurs …

Studies Of The Mechanics And Structure Of Shallow Magmatic Plumbing Systems, Mikel Díez

USF Tampa Graduate Theses and Dissertations

Volcanic activity, and the resultant deposits and structures at the Earth's surface, are the outcome of the inner workings of underground magmatic plumbing systems. These systems, essentially, consist of magma reservoirs which supply magma to the surface through volcanic conduits feeding volcanic eruptions. The mechanics and structure of plumbing systems remain largely unknown due to the obvious challenges involved in inferring volcanic processes occurring underground from observations at the surface. Nevertheless, volcanologists are beginning to gain a deeper understanding of the workings and architecture of magmatic plumbing systems from geophysical observations on active volcanoes, as well as from geological studies …

Doing Dignity At The Grace Café: An Ethnographic Exploration Of A Homeless Outreach Program, Courtney A. Glover

USF Tampa Graduate Theses and Dissertations

Homeless outreach programs vary widely in their approaches to client treatment. At the Grace Café, an organization that serves daily meals to people who are homeless, the concept of dignity is central to guest treatment. According to the café's ideology, the importance of providing food is secondary to serving with dignity. This research explores dignity as an ideal of client treatment at the Grace Café. Based on ethnographic research, this paper explores how dignity is communicated to volunteers, implemented in service, and challenged at the Grace Café.

Advances In Magnetic Resonance Electrical Impedance Mammography, Nataliya Kovalchuk

USF Tampa Graduate Theses and Dissertations

Magnetic Resonance Electrical Impedance Mammography (MREIM) is a new imaging technique under development by Wollin Ventures, Inc. in conjunction with the H. Lee Moffitt Cancer Center & Research Institute. MREIM addresses the problem of low specificity of magnetic resonance mammography and high false-positive rates, which lead to unnecessary biopsies. Because cancerous tissue has a higher electrical conductivity than benign tissue, it may serve as a biomarker for differentiation between malignant and benign lesions. The MREIM principle is based on measuring both magnetic resonance and electric properties of the breast by adding a quasi-steady-state electric field to the standard magnetic resonance …

Towards Regenerative Development: A Methodology For University Campuses To Become More Sustainable, With A Focus On The University Of South Florida, Richard Keirs Mcdonald Iii

USF Tampa Graduate Theses and Dissertations

The administrations of several universities have developed strategies to reduce the negative environmental effects created by their institutions. Because no single, comprehensive methodology to guide institutions to sustainability exists, these strategies range widely in scope. As well, the definition of "sustainability" differs for these various institutions, resulting in strategies ranging from small-scale recycling programs to major initiatives to incorporate green building and revamping curricula. This study attempts to create the first comprehensive methodology to guide university campuses and processes to become regenerative. Regenerative systems "produce more resources than needed, provide resources for other projects, and enhance [the] environment" (Bernheim 2003), …

Quebrada Communities In The Palmarejo Valley, Northwest Honduras, William A. Klinger

USF Tampa Graduate Theses and Dissertations

The spatial relationships that exist between ancient and modern settlement and natural resources have the potential to suggest ways in which humans organized themselves into communities. This study evaluates the applicability of the concept, "quebrada community," for understanding human-environmental relationships in northwest Honduras during the Late Classic period (AD 650-900). Existing archaeological, quantitative, and geological evidence for quebrada communities are linked with spatial data on two contemporary local communities, Palmarejo and Palos Blancos. A geographic information system (GIS) is constructed and implemented in order to achieve this goal. It is argued that there are specific relationships that exist between ancient …

Rational Synthesis Toward The Design Of Functional Metal-Organic Materials, Jarrod F. Eubank

USF Tampa Graduate Theses and Dissertations

Design of targeted functional solid-state materials for desired applications remains a scientific challenge. To overcome this hurdle, numerous synthetic strategies have been devised. It has been shown that molecules and/or clusters with pre-selected shapes, molecular building blocks (MBBs), can be utilized as units of chemical construction toward a final structure composed of those units.

Typically, in metal-organic structures metal-ligand directed assembly of the MBBs, via coordination chemistry in situ, leads to the final structure. The strength of the MBB formed and, consequently, the overall rigidity of the framework are essential in their use as porous materials for applications. Lack …

Brca1 185delag Mutant Protein, Brat, Amplifies Caspase-Mediated Apoptosis And Maspin Expression In Ovarian Cells, Joshua D. O'Donnell

USF Tampa Graduate Theses and Dissertations

Ovarian cancer is a deadly disease that kills an estimated 15,000 women annually in the United States. It is estimated that approximately 10% of ovarian cancers are due to familial inheritance. The most commonly mutated genes in familial ovarian cancer are BRCA1 and BRCA2. It has been reported that cells carrying the BRCA1 185delAG mutation undergo an enhanced caspase-3 mediated apoptotic response. Here, we report on the transfection of cDNA coding for the putative truncated protein product of the BRCA1 185delAG mutant gene into BRCA1 wild-type human immortalized ovarian surface epithelial (IOSE) cells and ovarian cancer cells. Cells transfected …

A Comparison Of Community-Based Centers Versus University-Based Centers In Clinical Trial Performance, Cynthia R. Stockddale

USF Tampa Graduate Theses and Dissertations

The success of a clinical trial is largely dependent on the clinical sites that enroll the subjects, complete the follow-up visits, and collect the data. Many clinical trials are conducted using multiple site locations. Choosing such sites to participate in a clinical trial is an important aspect of study implementation. In the past, multi-center clinical trials were conducted mainly using university-based centers. In the last few decades, private practice, or community-based, centers have been included more often in clinical trial research. As more community-based centers participate in clinical trials, it is crucial to examine how these centers might differ from …

Nanostructured systems composed of two or more technologically important materials are useful for device applications and intriguing for the new fundamental physics they may display. Magnetism at the nanoscale is dominated by size and surface effects which combined with other media lead to new spin dynamics and interfacial coupling phenomena. These new properties may prove to be useful for optimizing sensors and devices, increasing storage density for magnetic media, as well as for biomedical applications such as drug delivery, MRI contrast enhancement, and hyperthermia treatment for cancer. In this project we have examined the surface and interface magnetism of composite …

“To Know Where I Have Got To”: The Postmodern Chronotope In Beckett’S Malone Dies And Coetzee’S Foe, Brian J. Mcallister

USF Tampa Graduate Theses and Dissertations

This study addresses two works of fiction--Samuel Beckett's Malone Dies and J. M. Coetzee's Foe--and is separated into two chapters. The first chapter analyzes the indeterminate nature of postmodern space within the two novels as related to M. M. Bakhtin's idea of the chronotope found in his work The Dialogic Imagination. The second chapter addresses the self-reflexive creation of this postmodern space within each novel's hypodiegetic narratives and discussions of narrative creation within each respective diegetic narratives.

In each novel, characters as authors create or discuss "inner" narratives that reflect upon the way chronotopes are created in fiction …

Cost-Effectiveness Of Epidural Steroid Injections To Treat Lumbosacral Radiculopathy In Chronic Pain Patients Managed Under Workers’ Compensation, Sheila Mohammed

USF Tampa Graduate Theses and Dissertations

No conclusive evidence exists to determine that epidural steroid injections (ESIs) provide lasting improvements in chronic pain due to herniated discs, in the Workers' Compensation population. Recently, an article by Armon et.al was published by the American Academy of Neurology, which stated that the routine use of ESIs is not recommended and that further studies are needed to elucidate this controversy (Armon, Argoff, Samuels, & Backonja, 2007).

In 1998, back pain in the United States was estimated to have incurred total health-care expenditures of $90.7 billion. Medicare part B. claims in 1999 for 40.4 million individuals amounted to $49.9 million …
