The Artist And Her Muse: A Romantic Tragedy About A Mediocre And Narcissistic Painter Named Rachel Hoffman, Rachel Gavronsky Hoffman

USF Tampa Graduate Theses and Dissertations

Imagine a theater. Build one in your mind. I do not care if it is the largest theater in the universe or if it is the size of a shoebox. The theater can be an elaborate construction with gilded cherubs and priceless jewels. If you would prefer the theater to be a minimal design, imagine it that way. Maybe the theater is made out of glass or crystal. You can be all alone in the theater or maybe you are seated next to an alien, a cave man, or a robot.

As the curtain rises an enormous pipe organ is …

An Examination Of A Three-Dimensional Automated Firearms Evidence Comparison System, Natalie G. Carpenter

USF Tampa Graduate Theses and Dissertations

This thesis is an examination of a firearm identification system that creates a three-dimensional image of a bullet in order to record the depth and length of striations occurring along the bullet's surface. Ballistics evidence is an area of forensics in great need of further development. The advent of more sophisticated firearms such as semi-automatic and automatic weapons has increased the need for a matching system that connects bullets found at crime scenes with suspect guns. In the past, control bullets matching ones found at the crime scene have been test fired and then examined by a comparison microscope for …

Use-Wear Experiments With Sardinian Obsidian: Determining Its Function In The Neolithic, Teddi J. Setzer

This study focuses on identifying the function of obsidian tools from the Late Neolithic archaeological site of Contraguda on the Mediterranean island of Sardinia. The information obtained from use-wear analysis can provide information about changes in subsistence patterns, craft specialization, social differentiation and technology.

This research began by collecting geological samples of obsidian from two of the most exploited sources in the Monte Arci volcanic complex of Sardinia. Subsequently, an experimental set of tools was made from these samples, and they were used to work various raw materials that were presumably available in Sardinia during the Neolithic. Wear patterns were …

The Effects Of Overlearning On Long-Term Retention, Kelli M. Taylor

USF Tampa Graduate Theses and Dissertations

Overlearning is defined as the continued study of an item immediately after it has been correctly recalled once. Based on past studies, the effectiveness of overlearning is uncertain. In the present study, the effectiveness of overlearning was tested in 3 experiments. In Experiment 1, participants studied 10 city-country pairs (e.g. doba, chad) to either a low or high degree of learning and were tested 1, 3, or 9 weeks later. In Experiments 2 and 3, participants studied varying numbers of word-definition pairs (e.g. vizard, mask) for a constant total study time. They were tested between 1 and 4 weeks later. …

Mapping Porewater Salinity With Electromagnetic And Electrical Methods In Shallow Coastal Environments: Terra Ceia, Florida, Wm. Jason Greenwood

USF Tampa Graduate Theses and Dissertations

The feasibility of predicting porewater salinity based on calibrated surface electromagnetic methods is discussed in a coastal wetland on the southern banks of Tampa Bay in West-Central Florida. This study utilizes a new method to float commercial land based electromagnetic (EM) instruments in shallow marine waters of less than 1.5 meters. The floating EM-31 (Geonics, Ltd.) effectively sensed the magnitude and lateral extent of high and low salinity porewaters within mangrove lined ditches and ponds. Resistivity and EM geophysical methods are merged with direct sampling data to calibrate layers in electromagnetic models to infer shallow (<30m) groundwater salinity patterns. Initial marine resistivity surveys are necessary to discriminate between equivalent EM model solutions for seafloor conductivities beneath shallow (0.1-1.5m) marine (~30 ppt) waters. Using formation factors computed from nearby resistivity surveys, porewater conductivity predictions based on surface EM-31 and EM-34 measurements are successful at distinguishing overall porewater salinity trends.

Tracing The Source Of The Elephant And Hippopotamus Ivory From The 14th Century B.C. Uluburun Shipwreck: The Archaeological, Historical, And Isotopic Evidence, Kathryn Anne Lafrenz

USF Tampa Graduate Theses and Dissertations

The aim of this study is to establish the provenance of the elephant and hippopotamus ivory recovered from the 14th century B.C. Uluburun shipwreck in order to reconstruct the trade mechanisms and associated social relationships (e.g. diplomacy) operating in the eastern Mediterranean during the Late Bronze Age (LBA). Elephant ivory came either from Northeastern Libya, Southeastern Sudan via Egypt or northwestern Syria during this period. Hippopotamus ivory likewise was obtained from Syria, Palestine, or Egypt.

The Uluburun's cargo is reconstructed by the excavator, George Bass, as "royal," and primarily originates from Cyprus and Syro-Palestine. Indeed, LBA trade is largely understood …

Educational Choices Of Undergraduate Women In Public Relations: A Quantitative Study, Moira K. Davis

USF Tampa Graduate Theses and Dissertations

Public relations is one of the fastest growing majors chosen by college students throughout the United States, and most of these students are women. This thesis attempts to define the important role that women play in the practice of public relations and to determine why female students choose this major as their desired field of study more often then men. There is a need for such a study because in 1996 women accounted for only 37 percent of managers in marketing, advertising, and public relations, although they comprised 62 percent of all public relations specialists in this country. This research …

The Essay In The Postmodern Era, Xiqiao Wang

USF Tampa Graduate Theses and Dissertations

The overarching goal of this study is to suggest that the essay as a genre, although seeming to manifest the epistemological conceptions of the modern, possesses certain qualities from its origin that justify and strengthen its position in the paradigm of the postmodern condition. It is my argument that misconceptions about such qualities have led to its mistreatment by writing teachers in accordance with two dominant pedagogical approaches, formalism (current-traditionalism) and romanticism (expressivism). My argument requires a detailed examination of the political, historical and cultural reality that cultivated and nurtured the genre of the essay, and a major focus of …

Structural Diversity In Metal-Organic Nanoscale Supramolecular Architectures, Heba Abourahma

USF Tampa Graduate Theses and Dissertations

Supramolecular synthesis has gained much attention in recent years. Such an approach to synthesis represents an attractive alternative to traditional, multi-step synthesis, especially for making complex, nanoscopic structures. Of particular interest, in the context of this work, is the use of metal-organic interactions to direct the self-assembly of nanoscopic architectures. These interactions are highly directional, relatively "strong" (compared to other supramolecular interactions) and kinetically labile, which allows for "self-correction" and in turn the production, often in high yield, of defect-free products. This also means that a number of related, yet structurally diverse products (supramolecular isomers) could be isolated.

The work …

Fabrication And Testing Of A Cylindrical Ion Trap Microarray For Tunable Mass Spectrometers, Mangesh Telrandhe

USF Tampa Graduate Theses and Dissertations

This research presents a novel microfabrication approach and testing methodology for cylindrical ion trap (CIT) microarray tunable for mass- spectrometers. The growing interest in cylindrical ion trap (CIT) mass-spectrometers is primarily due to ease with which cylindrical geometry can be realized as compared to hyperbolic surfaces found in conventional quadrupole ion traps. Also due to the fact that the potential at the center of hyperbolic electrode in quadrupole ion trap and cylindrical electrode in cylindrical ion trap (CIT) does not differ significantly[2].

Since the RF voltage required to eject a given mass-to-charge ion scales as the square of the ion …

Learning From Spatially Disjoint Data, Divya Bhadoria

USF Tampa Graduate Theses and Dissertations

Committees of classifiers, also called mixtures or ensembles of classifiers, have become popular because they have the potential to improve on the performance of a single classifier constructed from the same set of training data. Bagging and boosting are some of the better known methods of constructing a committee of classifiers. Committees of classifiers are also important because they have the potential to provide a computationally scalable approach to handling massive datasets. When the emphasis is on computationally scalable approaches to handling massive datasets, the individual classifiers are often constructed from a small faction of the total data. In this …

Georeferencing Digital Camera Images Using Internal Camera Model, Alok Nagdev

USF Tampa Graduate Theses and Dissertations

The NASA Airborne Topographic Mapper (ATM) is a laser scanning instrument which is used mainly to collect dense topographic data over much of the conterminous US coastline. The inclusion of two digital cameras in consonance with the ATM instrument now gives 3-band (RGB) imagery apart from a very rich topographic data. This imagery, in its crude form, has limited applications due to it being not georeferenced and having a heavy camera lens distortions. As thesis, a processing system - Park-View - is developed to bring this imagery into a more suitable format for the scientists for analytical and interpretational purposes. …

Replacement Prioritization Of Precast Deck Panel Bridges In Florida, Ganesh Deshmukh

USF Tampa Graduate Theses and Dissertations

During the mid 70's and early 80's, several precast deck panel bridges were constructed in Florida. These utilize prestressed precast panels as stay-in-place forms and are designed to act compositely with a cast-in-place deck which is poured subsequently. Such bridges offer advantages of quicker construction and lower costs. However, several such bridges built in Florida developed extensive cracking and spalling. Following localized failures, the Florida Department of Transportation have decided to replace all 127 precast panel deck bridges in Districts 1 and 7. Since deck replacement is contingent on funding, it is necessary to develop a rational procedure to decide …

She Fell To Her Knees And Other Stories, Karen Brown Gonzalez

USF Tampa Graduate Theses and Dissertations

These collected stories represent a culling from a portion of work that shares a similar theme of loss--its manifestation, its channeling, by various fictional characters, into the palpable and sensate, into the physical world of the body. They are people, mostly women, who have lost their hold on the world to which they are accustomed, who become entangled in situations where their bearings are skewed, their judgment faulty, their decisions based solely on a physical, most often sexual, attraction that simultaneously depletes a sense of worth, while providing its semblance.

The loss stems, at times, as in "Manifold," from beyond …

Un Mandat, Deux Politiques : Les Effets De L’Inégalité De La Politique Mandataire Française En Syrie Et Au Liban, Catherine Glenn Ellis

USF Tampa Graduate Theses and Dissertations

In the early years of the twentieth century, the Ottoman Empire began to crumble due to external wars and internal rebellions dating from about 1908. Due to European influence at the end of the First World War, the Ottoman Empire lost much of its territory in 1919, including Palestine and Syria, comprised of modern-day Syria, Lebanon, Israel, Jordan, and Iraq. The European powers incited rebellion among the Middle Eastern peoples to the end of aiding their cause in the portions of the war fought in the Middle East. In return, they promised the Arabs independent nations; in the Treaty of …

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 …

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 …

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 …
