A Comparison Of Tone Burst Auditory Brainstem Response (Abr) Latencies Elicited With And Without Notched Noise Masking, Rachele M. Orsini

USF Tampa Graduate Theses and Dissertations

Objective: The air conduction click is currently the most widespread stimulus used to estimate the pure tone audiogram as part of auditory brainstem response (ABR) testing. The click is characterized by its broad spectral content and rapid onset, which may not make it the best choice for frequency specificity. An alternative stimulus is a short duration tone burst stimuli with notched noise masking. When obtaining an ABR using standard unmasked tone bursts, the brief stimulus onset may cause spectral splatter producing response contributions from unwanted regions of the cochlea; thus reducing the frequency specificity of the ABR. Notched noise masking …

Comparative Analysis Of Serologic Assays For The Detection Of Antibodies To Eastern Equine Encephalomyelitis Virus In Sentinel Chickens, Christy L. Voakes

USF Tampa Graduate Theses and Dissertations

Florida's mild climate supports year round enzootic transmission of arthropod-borne (arbo) viruses, such as St. Louis Encephalitis virus (SLEV), West Nile virus (WNV), and Eastern Equine Encephalomyelitis virus (EEEV). First isolated in 1960 from two Florida blue jays, Highlands J virus (HJV) is endemic to the state and vectored by the same mosquitoes as EEEV (Henderson et al, 1962). EEEV and HJV are both alphaviruses, but HJV is not pathogenic to humans, occasionally causes encephalitis in horses, and is a recognized pathogen in some bird species (turkeys, emus, etc) (Cilnis et al, 1996).

The Florida Sentinel Chicken Arboviral Surveillance …

Towards Adaptation Of Ofdm Based Wireless Communication Systems, Sharath Reddy Billoori

USF Tampa Graduate Theses and Dissertations

OFDM has been recognized as a powerful multi-carrier modulation technique that provides efficient spectral utilization and resilience to frequency selective fading channels. Adaptive modulation is a concept whereby the modulation modes are dynamically changed based on the perceived instantaneous channel conditions. In conjunction with OFDM systems, adaptive modulation is a very powerful technique to combat the frequency selective nature of mobile channels, while simultaneously attempting to fully maximize the time-varying capacity of the channel. This is based on the fact that frequency selective fading affects the sub-carriers unevenly, causing some of them to fade more severely than others. The modulation …

The Politics Of Being An Egg “Donor” And Shifting Notions Of Reproductive Freedom, Elizabeth A. Dedrick

USF Tampa Graduate Theses and Dissertations

As an Assisted Reproductive Technology (ART) that has been available for over twenty years, the transfer of healthy eggs from a presumably fertile woman into the womb of a woman diagnosed as infertile has become a common part of the landscape of human reproduction in the United States. Yet the general societal acceptance of this practice commonly known as "egg donation" oversimplifies the complex medical, ethical, and societal issues ignited by its use. In light of the limited critical discussions presently occurring about egg transfer, I will interrogate some of the silences and more ambiguous issues invoked by its practice. …

Light Quality And Phytoplankton Viability, Lisa A. Malick

USF Tampa Graduate Theses and Dissertations

A method is presented, using calculations of the underwater light field, to examine viability of phytoplankton at depth. For this study, viability is defined as the ability of phytoplankton to harvest, and efficiently convert enough photons into primary production to overcome metabolic demands. How the available light field influences the production environment is examined. Changes in water column constituents, such as chlorophyll and colored dissolved organic matter (CDOM) concentration, alter the spectral quality and quantity of the light field at depth. Certain species with specialized survival strategies, such as assemblages of photoprotective and light-harvesting accessory pigments, may be better-suited to …

From Just War To Just Peace: Re-Visioning Just War Theory From A Feminist Perspective, Naomi Malone

USF Tampa Graduate Theses and Dissertations

This paper studies the history of just war theory and critiques it from various feminist perspectives. Using a definition of war as inseparable from the system within which it is embedded, the paper contends that just war theory has been incorporated into the realist paradigm that predominates current political thought, making it susceptible to manipulation. Most importantly, this usurpation has shifted just war theory's focus from jus ad bellum to jus in bello considerations, seriously weakening its deterrent effects on war. The paper proposes its replacement with a just peace theory, discussing several existing frameworks and explaining the important part …

Modeling Time Space Prism Constraints In A Developing Country Context, Ram S. Nehra

USF Tampa Graduate Theses and Dissertations

Recent developments in microsimulation modeling of activity and travel demand have called for the explicit recognition of time-space constraints under which individuals perform their activity and travel patterns. The estimation of time-space prism vertex locations, i.e., the perceived time constraints, is an important development in this context. Stochastic frontier modeling methodology offers a suitable framework for modeling and identifying the expected vertex locations of time space prisms within which people execute activity-travel patterns. In this work, stochastic frontier models of time space prism vertex locations are estimated for samples drawn from a household travel survey conducted in 2001 in the …

Concerning Theories Of Personal Identity, Patrick, Bailey

USF Tampa Graduate Theses and Dissertations

The purpose of this thesis is to provide a brief examination of the historical accounts of philosophical theories of personal identity and show the influence that each has had on the development of contemporary theories. In doing so, the thesis explores the problems associated with these theories, attempting to establish a meta-theory (i.e. a theory about theories) of personal identity. What is demonstrated is that the fundamental problems of personal identity arise from issues related to the use of language, as well as assumptions involving the concept of personhood.

By demonstrating that our understanding of personhood is relative to frameworks …

This thesis investigates the performance of TCP and newer TCP versions over High Bandwidth Delay Product Channels (HBDPC), such as the on demand optical channels described above. In addition, …

An Online Strategy For Wavelet Based Analysis Of Multiscale Sensor Data, Alok K. Buch

USF Tampa Graduate Theses and Dissertations

Complex industrial processes are represented by data that are well known to be multiscaled due to the variety of events that occur in a process at different time and frequency localizations. Wavelet based multiscale analysis approaches provide an excellent means to examine these events. However, the scope of the existing wavelet based methods in the fields of statistical applications, such as process monitoring and defect identification are still limited. Recent literature contains several wavelet decomposition based multiscale process monitoring approaches including many real life process monitoring applications, such as tool-life monitoring, bearing defect monitoring, and monitoring of ultra-precision processes such …

A Comparison Of Exhaled Breath Nitric Oxide Between Old And Young Individuals, Robert L. Gordon

USF Tampa Graduate Theses and Dissertations

BACKGROUND: Older individuals suffer from higher rates of pulmonary infections than younger individuals. In addition, older individuals have increased morbidity and mortality due to pulmonary infections when compared to younger individuals. The physiological and immunological reasons for these aforementioned differences are not clear. Recently, non-invasive markers of the lung's physiologic and immunologic status have been recognized. This study employs one of these non-invasive markers, exhaled nitric oxide, in an attempt to determine how the airways may change with age, predisposing older individuals to pulmonary diseases and poorer outcomes as compared to younger individuals.

METHODS: Exhaled nitric oxide measurements were obtained …

Apalachicola’S Gold: Archaeology And History Of Tupelo Honey Production In Northwest Florida, Kelly S. Hockersmith

USF Tampa Graduate Theses and Dissertations

Several archaeological sites in the lower Apalachicola River Valley have evidence of beekeeping in the late nineteenth to early twentieth centuries. At least two of these are also prehistoric sites (Depot Creek, 8Gu56 and Clark Creek, 8Gu60), which are Rangia (clam) shell mounds. Both sites are deep in the river swamp, which has the largest stand of tupelo trees in the world. The valley has a long tradition of beekeeping. Apiarists (beekeepers) would bring their bees by boat to remote locations in the swamps during the short tupelo flowering season to take advantage of the extensive forest. Tupelo honey has …

Identification And Measurement Of Two Factors Affecting The Long-Term Outcomes Of Public Relations Programs: Public Image And Public Trust, Kimberly B. Amendola

USF Tampa Graduate Theses and Dissertations

This study explores the most current theories surrounding organization-public relationship measurement, which is one approach used to verify the effectiveness of public relations programs. The study attempted to define and test two new factors that may affect organization-public relationships, which are identified as public image and public trust. Existing factors used to test such relationships, such as trust, satisfaction, commitment, and control mutuality, focus on testing the perceptions stakeholders have about an organization based upon their interpersonal relationship with that organization. However, in organizations where the dominant coalition still does not view public relations as …

Significance Of The European Investment Bank, Maria L. Pisaneschi

USF Tampa Graduate Theses and Dissertations

Since the implementation of the Treaty of Rome in 1958, the Common Market of six European states has grown to the European Union of twenty-five states as of May 2004. From the outset, the integration of these states into a single economic system has made more apparent the differences in levels of economic development among and within the member states. The original members of the Common Market were aware of these regional differences in 1958 and created the European Investment Bank as part of the Treaty of Rome to provide investment funds to reduce the development gap among the member …

To date, most computer aided analysis applications are software driven and normally require long processing times. Digital filtering is often the initial stage in processing mammograms for both automated detection and tissue characterization, which relies on Fourier analysis. In this research the main objective is to lay the groundwork for converting software driven mammography applications to hardware implementations by using Application-Specific Integrated Circuits (ASICs). The long-term goal is to increase processing speed. This research focuses on achieving the main objective by using one specific mammographic image …

Core Issues In Graph Based Perceptual Organization: Spectral Cut Measures, Learning, Padmanabhan Soundararajan

USF Tampa Graduate Theses and Dissertations

Grouping is a vital precursor to object recognition. The complexity of the object recognition process can be reduced to a large extent by using a frontend grouping process. In this dissertation, a grouping framework based on spectral methods for graphs is used. The objects are segmented from the background by means of an associated learning process that decides on the relative importance of the basic salient relationships such as proximity, parallelism, continuity, junctions and common region. While much of the previous research has been focussed on using simple relationships like similarity, proximity, continuity and junctions, this work differenciates itself by …

Adaptive Digital Predistortion Linearizer For Power Amplifiers In Military Uhf Satellite, Jayanti Patel

USF Tampa Graduate Theses and Dissertations

The existing UHF Satellite Communications (SATCOM) transponders used for military applications use efficient, saturated power amplifiers, which provide one earth-coverage antenna beam. The amplifier is dedicated to small frequency band and only handles a few carriers simultaneously.

The communications capacity needed to support future military forces on the move will require satellite payload power amplifiers to support hundreds of channels simultaneously, with the channels spread over the entire military UHF SATCOM band. To meet the capacity requirements and simultaneously meet the out-of-band emission, power amplifiers will have to be highly linear. The high-efficiency, ultra-linear power amplifier architecture proposed to support …

Benefit Of Staged Cooling In Shrink Fitted Composite Cylinders, Nathaniel Oren Collier

USF Tampa Graduate Theses and Dissertations

To assemble the fulcrum of bascule bridges, a trunnion is immersed into liquid nitrogen so that it can be shrunk fit into the hub. This is followed by immersing the resulting trunnion-hub assembly into liquid nitrogen so that it can be then shrunk fit into the girder. On one occasion in Florida, when the trunnion-hub assembly was put into liquid nitrogen, development of cracks on the hub was observed. Experimental and numerical studies conducted since 1998 at University of South Florida show that the cracking took place due to combination of high interference stresses in the trunnion-hub assembly, low fracture …

Level Of Demoralization As A Predictor Of Stage Of Change In Patients With Gastrointestinal And Colorectal Cancer, Cheryl Anne Cockram

USF Tampa Graduate Theses and Dissertations

Demoralization is a concept that evolved out of the study of individuals under stress. It is defined as the combination of distress and subjective incompetence in the presence of inadequate social bonds. When patients with alcohol abuse problems are diagnosed with cancer they may become demoralized and be unable to summons adequate resources to address issues associated with changing their addictive behavior. The Stage of Change Model (SOC), one of the primary approaches in addiction therapy, is used to guide individuals through the process of behavioral change.

This two phase study examined the relationship between demoralization and stage of change. …

Ammonia Flux At The Air/Water Interface Of Tampa Bay, Constance Anne Mizak

USF Tampa Graduate Theses and Dissertations

An ammonia emissions inventory discovered that 90% of the ammonia emitted from Pinellas, Hillsborough, and Polk counties, originated from the latter two counties. This finding is significant and suggests that a substantial portion of the ammonia deposited to Tampa Bay is transported with easterly air masses.

Ammonia and ammonium concentrations at the coastal Gandy Bridge site were seasonally and diurnally consistent, but the rural Sydney site showed greater variability. It was determined that wind direction was the most influential parameter affecting the Gandy Bridge site, which supports the hypothesis that an advection of ammonia from the east is a major …

Detection And Quantification Of Karenia Brevis Blooms On The West Florida Shelf From Remotely Sensed Ocean Color Imagery, Jennifer P. Cannizzaro

USF Tampa Graduate Theses and Dissertations

Karenia brevis, a toxic dinoflagellate species that blooms regularly in the Gulf of Mexico, frequently causes widespread ecological and economic damage and can pose a serious threat to human health. Satellite-based ocean color imagery may provide a means for detecting and monitoring blooms, providing early alerts to coastal communities. However, a technique for discriminating K. brevis from other chlorophyll-containing algae is required. Between 1999 and 2001, a large bio-optical data set consisting of spectral measurements of remote-sensing reflectance (Rrs(lambda)), absorption (a(lambda)), and backscattering (bb(lambda)) along with chlorophyll a concentrations was collected on the central west Florida shelf (WFS) as …
