USF Tampa Graduate Theses and Dissertations

Gopher tortoise (Gopherus polyphemus) population sizes have drastically declined in the past 100 years. Much of this decline has been attributed to past human predation, to habitat loss from human development, and potentially to the recently discovered upper respiratory tract disease. An understanding of the genetic structure among populations is critical for the long-term success of relocation and other management strategies. This research focuses on the development of a suite of genetic markers and the answers they provided to questions concerning present day population genetics and its use in management.

Modeling Dynamic Interactions In A Software Development Project, Chetan D. Vajre

USF Tampa Graduate Theses and Dissertations

Software industry is getting very competitive in the wake of recession. In most cases, an organization that quotes a lower price and promises to deliver the product at the earliest walks away with the project. But the factor of quality of the product delivered is also very important because that in turn determines the reputation of an organization, which also plays an important role in getting the next project.

Interactions in a software development are dynamic in nature and involve human factors. Models are built taking into account all possible factors so as to present a realistic picture of the …

Count Or Pointcount: Is Percent Octocoral Cover An Adequate Proxy For Octocoral Abundance?, Matthew J. Lybolt

USF Tampa Graduate Theses and Dissertations

The Florida Keys Coral Reef Monitoring Project (CRMP) began video transect sampling in 1996 and has continuously monitored 107 Florida Keys stations through 2002. The video was downward pointing and produced images from which planar projection data were calculated to determine percent cover of living benthic organisms. An absence of data assessing correlation between octocoral percent cover and octocoral abundance motivated a study to compare octocoral percent cover with abundance data acquired from the same video transects. The methods employed to extract octocoral abundance data from videotape were validated. Temporal changes in octocoral abundance, size and taxonomic group were determined …

These interactive digital cultural forms have encouraged collaborative efforts that would have otherwise been difficult or even impossible to achieve before the advent of digital technology. In addition, this element of interactivity has redefined the traditional relationship between artist and audience. As …

Alexander Pope's Opus Magnum As Palladian Monument, Cassandra C. Pauley

USF Tampa Graduate Theses and Dissertations

The overarching goal of this study is to suggest that Alexander Pope did not abandon his project for a "system of ethics in the Horatian way," but rather that in his final days he did find a way to unite the parts at hand into a viable whole. Constructing such an argument, however, requires a similar building up from the parts, and so the core focus becomes a study on the way the image of an arch can serve as a metaphor for Pope's reconciliation scheme in his Moral Essays as he "steers betwixt" seeming opposites.

To justify this approach, …

Placement Of Utilities In Right Of Way Model Using Fuzzy And Probabilistic Objective Coefficients, Vijayakumar S. Shanmugam

USF Tampa Graduate Theses and Dissertations

This thesis focuses on a decision-making model for finding the locations for placement of utilities in roadway corridors. In recent years, there has been a rapid growth in the volume of traffic on roadways and in the number of utilities placed in Right of Ways. The increase in the demand for utilities is making it more difficult to place all the utilities within the Right of Way and also provide safe roads and highways with good carrying capacity. The public agencies approving the location for utilities are now using a first come first served method, which provide neither an efficient …

Pipe Dreams And Primitivism: Eugene O'Neill And The Rhetoric Of Ethnicity, Donald P. Gagnon

USF Tampa Graduate Theses and Dissertations

Eugene O'Neill included within his vision of humanity a series of complex, emotionally and psychologically developed black characters. Despite critical controversy over his methods or effectiveness, from his eerily silent mulatto in "Thirst" through the grandiose incarnation of The Emperor Jones and the everyman of Joe Mott and The Iceman Cometh, O'Neill created characters of African descent that thrilled and infuriated critics and audiences alike.

A closer exploration of the issues involved in his portrayal of ethnically identified characters seems necessary, an exploration that does not limit itself to an interrogation of ethnicity per se in O'Neill's plays, but …

A Distributed Routing Algorithm For Er-Lsp Setup In Mlps Networks, Naga Siddhardha Garige

USF Tampa Graduate Theses and Dissertations

The rapid growth of the Internet, in the last few years, has generated a need to enhance the existing IP networks in the areas of availability, dependability and scalability in order to provide a mission critical networking environment. In contemporary IP networks, data packets are routed as a function of the destination address and a single metric such as hop-count or delay. This approach tends to cause message traffic to converge onto the same link, which significantly increases congestion and leads to unbalanced network resource utilization. One solution to this problem is provided by Traffic Engineering (TE), which uses, bandwidth …

With increasing encroachment on natural communities by anthropogenic activity, it is important to understand the functions of natural ecosystems in an effort to conserve natural areas. A first-hand study of the population dynamics of South Florida Slash Pine (P. elliottii Engelm. var. densa) following a fire event provided insight to its recovery and dispersal following a fire. A natural fire (lightning-induced) occurred in the spring of 2000 at the T. Mabry Carlton, Jr. Reserve, Sarasota County, providing an opportunity to study aspects of slash pine in relation to fire. One objective of my research was to look at …

An Investigation Of Bga Electronic Packaging Moiré Interferometry, Norman Rivers

USF Tampa Graduate Theses and Dissertations

As technology progresses towards smaller electronic packages, thermo-mechanical considerations pose a challenge to package designers. One area of difficulty is the ability to predict the fatigue life of the solder connections. To do this one must be able to accurately model the thermo-mechanical performance of the electronic package. As the solder ball size decreases, it becomes difficult to determine the performance of the package with traditional methods such as the use of strain gages. This is due to the fact that strain gages become limited in size and resolution and lack the ability to measure discreet strain fields as the …

Attention-Deficit/Hyperactivity Disorder: General Education Elementary School Teachers' Knowledge, Training, And Ratings Of Acceptability Of Interventions, Stacey Small M.A.

USF Tampa Graduate Theses and Dissertations

Given that researchers estimate approximately one child in every classroom has Attention-Deficit/Hyperactivity Disorder (ADHD), and that most of these students are served in the general education classroom, it is imperative that general education teachers know how to effectively teach these students. Seventy-two general education elementary school teachers completed a survey containing demographic information, a knowledge of ADHD questionnaire, and a survey on interventions for students with ADHD. Results indicated that teachers scored an average of 57% correct on the Knowledge of Attention Deficit Disorders Scale (KADDS), scoring statistically significantly higher on the Symptoms/Diagnosis subscale compared to the General and Treatment …

The Role Of Individual Differences In Learning Alcohol Expectancy Associations, Howard R. Steinberg

USF Tampa Graduate Theses and Dissertations

Alcohol expectancy theory suggests that genetically influenced personality characteristics may lead to differential acquisition of expectancy information, and that this information then may serve as one mediational pathway for alcoholism risk. Research has already shown that expectancy information can predict and even mediate risk, but it has yet to be shown that personality traits can influence the acquisition of alcohol expectancy information. To that end, personality characteristics known to be risk factors for the development of excessive alcohol use were assessed in 83 male undergraduates. In addition, each participant studied, in a paired-associate learning/cued-recall test paradigm, a list of word …

Hazard Vulnerability In Socio-Economic Context: An Example From Ecuador, Lucille Richards Lane

USF Tampa Graduate Theses and Dissertations

How people pereceive the risks associated with natural hazards contributes to their willingness to take protective action. Such action may be constrained by prevailing socio-economic and place-specific conditions that restrict or inform the choice of protective measures available to the individual. Vulnerability to the impacts of extreme geophysical events increases when the range of alternatives is limited or misinformed.

Many evacuees from a potentially violent volcanic eruption in Ecuador returned to their home town of Banos while it was still under an evacuation order in 2000 and considered to be a high risk area by officials. The research examined four …

Dwellness: A Radical Notion Of Wilderness, Martin J. Wortman

USF Tampa Graduate Theses and Dissertations

The contemporary concept of wilderness, which is central to environmental theory and activism, is both a help and a hindrance to government policy and to popular environmental beliefs. The Judeo-Christian religious tradition and Locke's property theory provides much of the western cultural and historical basis of humans' environmental attitudes that basically engender exploitation. I argue that a more precise interpretation of Genesis and of Locke reveals that both sources actually promote environmental stewardship while decrying ecological abuse. Next I analyze the history and shortcomings of various wilderness concepts. These shortcomings are all forms of an exclusionist mentality and result in …

Nutrient Uptake By Seagrass Communities And Associated Organisms: Impact Of Hydrodynamic Regime Quantified Through Field Measurements And Use Of An Isotope Label, Christopher David Cornelisen

USF Tampa Graduate Theses and Dissertations

Seagrass communities are composed of numerous organisms that depend on water-column nutrients for metabolic processes. The rate at which these organisms remove a nutrient from the water column can be controlled by physical factors such as hydrodynamic regime or by biological factors such as speed of enzyme reactions. The impact of hydrodynamic regime on rates of nutrient uptake for seagrass (Thalassia testudinum) communities and for organisms that comprise the community (seagrass, epiphytes, phytoplankton, and microphytobenthos) was quantified in a series of field flume experiments employing the use of ¹⁵N-labeled ammonium and nitrate.

Rates of ammonium uptake for …

Performance Verification Of Personal Aerosol Sampling Devices, Steven T. Luecke

USF Tampa Graduate Theses and Dissertations

International standards establish criteria for size-selective aerosol sampling for industrial hygiene. Commercially available aerosol samplers are designed to conform to these criteria. This study uses semi-monodispersed aerosols generated in a vertically aligned test chamber to compare the performance of three commercially available respirable dust samplers, one of which can simultaneously sample for thoracic and inhalable dust fractions. Comparison methods are used to calculate a theoretical fractional value based on the appropriate sampling conventions of the total dust concentration and size distribution of test materials. Performance of actual samplers can be conducted by comparing observed results to the theoretical value. Results …
