Sound Production And Behavior Of Red Grouper (Epinephelus Morio) On The West Florida Shelf, Misty D. Montie

USF Tampa Graduate Theses and Dissertations

Red grouper (Epinephelus morio) are long-lived, commercially important, soniferous fish belonging to the family Epinephelidae. Found throughout the western North Atlantic and Gulf of Mexico, they are protogynous hermaphrodites, and peak spawning occurs from March through May. Unlike many grouper species, red grouper do not form large spawning aggregations; rather, they form small polygynous groups, and remain in relatively close proximity to rocky depressions excavated in the sandy bottom by males. This excavation activity creates structure and habitat for a wide variety of species, and as a result, red grouper are a keystone species on the West Florida Shelf. While …

Diffuse Degassing And The Hydrothermal System At Masaya Volcano, Nicaragua, Sophie C. P Pearson

USF Tampa Graduate Theses and Dissertations

Hydrothermal systems change in response to volcanic activity, and in turn may be sensitive indicators of volcanic activity. Fumaroles are a surface manifestation of this interaction. We use time series of soil temperature data and numerical models of the hydrothermal system to investigate volcanic, hydrologic and geologic controls on this diffuse degassing.

Soil temperatures were measured in a low-temperature fumarole field located 3.5 km from the summit of Masaya volcano, Nicaragua. They respond rapidly, on a time scale of minutes, to changes in volcanic activity also manifested at the summit vent. The soil temperature response is repetitive and complex, and …

Evaluation Of The Flicker Effect As A Generative Strategy In Enhancing Computerbased Instruction (Cbi) Of Visual Recognition And Classification, Ping Luo

USF Tampa Graduate Theses and Dissertations

Few studies address the question of the technology-based instructional methods of visual patterns, so the overarching purpose of this study was to investigate the effects of three treatments on pattern recognition. Specifically, with a pretest-posttest control group experimental study, the effectiveness of three instructional strategies, a flicker treatment, a no-flicker treatment, and a comparison treatment, (groups respectively analyzing sequential displays of two similar images with and without a blank screen in between and simultaneous displays of two images), was compared based on recognition (memory) and classification (transfer) test scores. The group differences in learning effectiveness and efficiency were also measured …

Comparison And Improvement Of Different Access Methods In Femtocell Networks, İbrahim Demirdögen

USF Tampa Graduate Theses and Dissertations

A variety of wide band wireless systems have been pushed towards their limits in order to meet growing interest for high data rate in wireless communications.In particular, the limit due to the spectrum scarcity forces communication systems to utilize the spectrum resource at maximum efficiency level. One of the methods that allow effective spectrum employing is to cover multiple systems over same spectrum source by allowing bearable interference to occur between them. Femtocells have been recently introduced as a remedy to spectrum scarcity and coverage problems in current cellular structures. Femtocells are personal use base stations and they share the …

Religion And Resistance: The Role Of Islamic Doctrine In Hamas And Hezbollah, Matthew Lawson

USF Tampa Graduate Theses and Dissertations

The recent conflict in Gaza between the state of Israel and Palestinians led by Hamas has again brought the question of Palestinian statehood to the attention of the international community. Religion has often been mentioned as a cause for the conflict between the two, as well as a reason for the perceived instability of the Middle East. It is within this frame of reference that this study takes place. This study attempts to use this emergence in current events as the starting point for the interaction between religion and resistance movements, examining the incorporation of Islamic doctrine into the actions …

The Third Realm: Suburban Identity Through The Transformation Of The Main Street, Alberto Rodriguez

USF Tampa Graduate Theses and Dissertations

When one researches the city, the neighborhood appears as an indispensable building block. Kevin Lynch, In The Image of a City, suggests that neighborhoods are "the basic element of the city" and the main way "most people structure their city". Furthering the idea of the neighborhood as a building block of the city, Sidney Brower discusses the need for different types of neighborhoods to allow for a diverse social setting to create diversity in the city. The research put forward by Lynch and Brower shows the idea of the neighborhood as a strong concept in older cities. However, the concept …

Elevating Communication, Thao Thanh Nguyen

USF Tampa Graduate Theses and Dissertations

The products of vehicular transportation have led the modern traveler into a crisis of place. The modern journey that is held within ceaseless flux, confine movement to edges facilitating prompt passage yet negating active participation. These edges govern movement, highlighting points of destination while simultaneously obscuring our journey in between travels. The limited participation and extended observation of one's place within the concurring boundaries renders the senses dormant, causing passivity and reluctance to participate or communicate with the city. These lines of movement, demanding our attention toward beginning and end but omitting the middle, transforms the city, home, and place …

Refusing To Go Silently: Female Wit As Combating A Culture Of Silence In Frances Burney And Elizabeth Inchbald's Texts, Megan M. Weber

USF Tampa Graduate Theses and Dissertations

In the hands of two prominent authors, Elizabeth Inchbald and Frances Burney, a critical paradox concerning female silence arises: while both authors operate very successfully in the publishing world, both do so while subverting impositions of silence, exhibiting a clear breach of propriety. An examination of Inchbald's novel A Simple Story and play Wives as they Were, Maids as they Are and Burney's novel Cecilia and play The Witlings, elucidates how each author adapts literary genres to portray female wit, exposing eighteenth-century impositions of silence in the process. By engendering female characters with the ability to employ humor as …

Analysis Of Two Strategies For Structuring Medicare Reimbursement To Maximize Profitability In Acute Care General Hospitals, James D. Barrington

USF Tampa Graduate Theses and Dissertations

The healthcare literature sometimes cites Medicare as a negative determinant of hospital profitability. However, a review of Florida acute care short-term general hospital data revealed a subset of profitable hospitals with high percentages of their revenue structure comprised of Medicare reimbursements. Some investigators might contend that these hospitals are just better managed; that hospital profitability is not related to patient mix or payer source. Although good management enhances financial health, there are perhaps other reasons why certain hospitals can become profitable with Medicare as their primary revenue source.

Research findings indicate there is wide geographic variability shown for per-capita volumes …

Founding Fathers: An Ethnic And Gender Study Of The Iliadic Aeneid, Rob Brannon

USF Tampa Graduate Theses and Dissertations

In a 2005 work, Yasmin Syed concluded that the Aeneid created for ancient readers an idea of Romanness that was inclusive for all and not founded along strict genetic lines. Under this hypothesis, the Aeneid offers a sort of blueprint for becoming Roman, one in which biological descent from Aeneas is unnecessary. Syed reached this conclusion by analyzing themes of ethnicity and gender, in particular the ethnic other represented by the epic's female characters. This was accomplished in the manner so often chosen by Vergil scholars-by limiting analysis to the first half of the epic. The work concludes with an …

Wayfinding In Architecture, Jason Brandon Abrams

USF Tampa Graduate Theses and Dissertations

In many of today’s modern educational institutions, architects have designed spaces that are disconnected and difficult for users to navigate. The underdevelopment of directional guides more accurately describes common issues of wayfinding. Wayfinding is a term used to describe user experience and orientation within an environmental context. When accomplished successfully, wayfinding contains order and simplicity achieved through five hierarchical components including; point of reference, location of information, determining a path to take, maintaining that path, and access or denial of the path chosen.

Currently, the Rietveld Academie in Amsterdam, a design institution of higher learning, lacks the components necessary to …

Struggle In The Sunshine City: The Movement For Racial Equality In St. Petersburg Florida 1955-1968, Peyton L. Jones

USF Tampa Graduate Theses and Dissertations

Recent decades have seen a shift in the focus of civil rights historiography. Building upon the exhaustive studies of national figures and events, and in search of new perspectives, many historians have concentrated on local movements often ignored or forgotten. Other than the work of a few local scholars, the civil rights movement as it occurred in St. Petersburg, Florida, has received little attention. Furthermore, the limited scholarship lacks the cohesion necessary to compare and contrast the movement with similar events throughout the state and across the nation. The story of St. Petersburg's active and significant struggle for social equality, …

Sports Fans’ Media Usage At A Kansas City Chiefs’ Fan Club, Robert J. Huebert

USF Tampa Graduate Theses and Dissertations

The media play a major role in every part of American society by distributing content that has value to individuals, and a National Football League (NFL) sports fan club is no different. This study examines how members of a Kansas City Chiefs' fan club use media to stay connected to their team and socialize with fellow members. Social identification theory explains that when an individual comes together with one or more individuals with like-minded interests, they form social bonds. Their shared interests allow them to disseminate Chiefs' information through content gathered from media usage. To understand how the Chiefs' fans …

Headline Hawai`I: Racial Aloha In Kama`Aina News, Cory J. Weaver

USF Tampa Graduate Theses and Dissertations

The front page of Hawai`i's largest-circulated newspaper - The Honolulu Star-Bulletin - was reviewed for a three-month period: March 1, 2008 - June 1, 2008, to examine representations of race in a media market where Caucasian individuals are the minority. Analysis of the newspaper seeks to present a greater understanding of ethnic portrayals in island news and examines ethical implications that have/can arise from adopting journalistic values typical of "white news" or mainstream reporting practices in areas where the mainstream is, in fact, the minority.

Extending Situational Crisis Communication Theory: Attitude And Reputation Following The 2004-05 Nhl Lockout, Melanie Formentin

USF Tampa Graduate Theses and Dissertations

This exploratory case study positions the 2004-05 National Hockey League (NHL) lockout as an organizational crisis, studying it within a Situational Crisis Communication Theory (SCCT) frame. A mixed methodology approach used qualitative and quantitative content analyses and a survey of NHL fans to gauge the NHL's reputation five years after the lockout. For the content analyses, 282 newspaper articles from 7 newspapers in the U.S. and Canada were coded for SCCT variables and presentation of the lockout by news writers. NHL fans (n = 140) were surveyed with the goal of assessing SCCT variables as predictors of attitude. Results …

Upgrading Design: A Mechatronic Investigation Into The Architectural Product Market, Matthew Gaboury

USF Tampa Graduate Theses and Dissertations

It was first stated 200 years ago, and reiterated numerous times since, that "architecture is frozen music". While this romantic analogy sufficiently satisfies many in the realm of architecture, it actually is a sad way of defining an idea so inherently lively. Goethe's quote conjures up the notion of a world that is silent, one in which we can see the notes but never hear the music because we are trapped by stasis in time. Like the note admired on a piece of paper, architecture in this world is static regardless of the changing conditions around it.

What if the …

From Airport To Spaceport: Designing For An Aerospace Revolution, Paula Selvidge

USF Tampa Graduate Theses and Dissertations

"Airports will shape business location and urban development in the 21st century as much as highways did in the 20th century, railroads in the 19th and seaports in the 18th" - John D. Kasarda, Ph.D. Kenan-Flagler Business School, University of North Carolina http://www.aerotropolis.com/author.html

I say, spaceports will shape the urban development of the 21st century, more than airports, bringing about an aerospace revolution. Just as new technologies triggered the global revolutions of the past, so the invention of reusable spacecraft will revolutionize transportation.

The invention of such spacecraft suggests the need for a different kind of transportation hub: a spaceport. …

Local Environmental Perceptions And Cognitive And Affective Learning In A Rural, Andean Community In Mollepata, Peru, Luisella Mazzone De Angelis

USF Tampa Graduate Theses and Dissertations

This study examines the linkages between environmental field trips and cognitive and affective gains in two groups of homogenous elementary-aged students in Mollepata, Peru. One group participated in an environmental field trip to a local, non-profit farm (Aprodes) to explore watershed and agricultural issues. The second group received the same content within the classroom setting. The research also examines the environmental perceptions of local residents via semi-formal open-ended interviews to assess their environmental awareness and their willingness to receive environmental education services from an outside organization.

Data were collected both quantitatively and qualitatively via pre and post tests containing science …

Perceiving Architecture: An Experiential Design Approach, Ashley Verbanic

USF Tampa Graduate Theses and Dissertations

Perception of the physical environment is largely dependent on a range of criteria which are not always readily identifiable. Such a difficulty to identify how a person perceives an environment creates a situation in which architects and designers can easily neglect this idea of the individual user and their experience.

Through the design of a preschool, this thesis focuses largely on understanding how children and other users perceive and interact with their environments. The design process employed synthesizes user based research and analysis of environmental cues such as light, sound, and smells and their effect on how we interpret a …

The Psychometric Validation Of The Physical Body Experiences Questionnaire, Jessie E. Menzel

USF Tampa Graduate Theses and Dissertations

Embodiment is defined as a state in which one experiences one's body as an essential and loved aspect of one's lived experiences, a potential protective factor against body image and eating disturbance. While qualitative studies have been conducted to examine the nature of embodiment, a quantitative measure has not yet been created. The Physical Body Experiences Questionnaire was rationally derived as a measure of embodiment based on focus groups, literature reviews, and expert review. These qualitative methods resulted in a 32-item scale measured on a 7-point Likert scale. Based on the results of a pilot study conducted with 670 female …

The Waiting Unknown: Stories, James R. Miller

USF Tampa Graduate Theses and Dissertations

These collected stories are a narrative exploration of a collective life in middle‐class suburbia. Here the reader is introduced to a troop of characters who share a community but yet they are adrift in the atmosphere between identity and memory. At times, as in “When to Lie” and “Afraid of the Question” we see conflict arise when the suburban religious dogma alters character identity, leaving behind haunting memories and scar tissue. Memory and identification play an important roll when, as in “Rx” the protagonist is faced with the sudden loss of his family as he struggles to keep their memories …

Mubarak’S Machine: The Durability Of The Authoritarian Regime In Egypt, Andrea M. Perkins

USF Tampa Graduate Theses and Dissertations

The Egyptian authoritarian regime is a mammoth machine created and headed by President Hosni Mubarak as an instrument for the exercise of his own power. His ability to influence every facet of the character of Egypt lies in his previous career experience, the involvement in politics of his immediate family, his commitment to unpopular but lucrative foreign policies, and the bureaucratic obstacle course he created for opposition entities to navigate.

Through persistent efforts to prepare himself for national leadership prior to gaining power, then to consolidate his power in the institutions of Egypt, Mubarak has built a state organization with …

Articulating Social Change In Puerto Rico: Environmental Education As A Model For Youth Socio-Political Development And Community-Led School Reform, Federico Cintrón-Moscoso

USF Tampa Graduate Theses and Dissertations

Recent attempts at developing an environmental education agenda in public schools emphasize the need to foster greater public awareness about environmental rights, issues, and solutions, while producing citizens with the knowledge and skills needed to address the ecological challenges of contemporary society. However, some scholars have argued that the attempt to integrate environmental principles into the school curricula has created a conflict between the politically-oriented goals of environmental education and the more passive practices of uncritical assimilation and reproduction found in many schools today (Stevenson 2007). Moreover, although there is a need for public schools to take on the challenge …

Effects Of Ozone On Blood Components, Daniela Sloan

USF Tampa Graduate Theses and Dissertations

Previous studies on the medical use of ozone therapies show a very diverse array of results, from ozone reducing the amount of HIV virus in the blood, to no effect, to causing the death of several patients due to pulmonary embolism and infections. However, ozone therapies are widely used in Europe and considered medically safe. In the U.S., doctors in 28 states use ozone therapies.

The objectives of this study were to investigate the effects of medical grade ozone at varying concentrations used in ozone therapies. These were achieved by evaluating the C-reactive protein, erythrocyte sedimentation rate, total reduced and …

Design And Evaluation Of A Green Bittorrent For Energy-Efficient Content Distribution, Jeremy H. Blackburn

USF Tampa Graduate Theses and Dissertations

IT equipment has been estimated to be responsible for 2% of global CO2 emissions and data centers are responsible for 1.2% of U.S. energy consumption. With the large quantity of high quality digital content available on the Internet the energy demands and environmental impact of the data centers must be addressed. The use of peer-to-peer technologies, such as BitTorrent, to distribute legal content to consumers is actively being explored as a means of reducing both file download times and the energy consumption of data centers. This approach pushes the energy use out of the data centers and into the homes …

Parallel Genetic Algorithm Engine On An Fpga, Mark La Spina

USF Tampa Graduate Theses and Dissertations

The field of FPGA design is ever-growing due to costs being lower than that of ASICs, as well as the time and cost of development. Creating programs to run on them is equally important as developing the devices themselves. Utilizing the increase in performance over software, as well as the ease of reprogramming the device, has led to complex concepts and algorithms that would otherwise be very time-consuming when implemented on software. One such focus has been towards a search and optimization algorithm called the genetic algorithm. The proposed approach is to take an existing application of the genetic algorithm …

Biosynthesis Of Fatty Acid Amides, Emma K. Farrell

USF Tampa Graduate Theses and Dissertations

Primary fatty acid amides (PFAMs) and N-acylglycines (NAGs) are important signaling molecules in the mammalian nervous system, binding to many drug receptors and demonstrating control over sleep, locomotor activity, angiogenesis, vasodilatation, gap junction communication, and many other processes. Oleamide is the best-studied of the PFAMs, while the in vivo activity of the others is largely unstudied. Even less is known about the NAGs, as their discovery as novel compounds is much more recent due to low endogenous levels. Herein is described extraction and quantification techniques for PFAMs and NAGs in cultured cells and media using solvent extraction combined with …

Use Of Model Compounds To Study Potential Removal Of Pharmaceuticals Using Octolig®, Wen-Shan Chang

USF Tampa Graduate Theses and Dissertations

The existence of pharmaceuticals in the environment has some adverse effects, and may pose threat to the organisms in the environment. The possibility of removing certain pharmaceuticals from wastewater was tested using Octolig®, a commercially available material with polyethyldiamine moieties covalently attached to high-surface area silica gel. Selected drug models were subjected to column chromatography in efforts to effect removal by means of ion encapsulation, the effectiveness of which would depend upon having appropriate anionic functional groups. The experimental results suggested that the model compounds, Rose Bengal, Eosin Y, Erythrosine , ZPS, and Lissamine Green B were successfully encapsulated by …

A Philosophical Inquiry On The Valuation And Selection Of Musical Materials For Culturally Diverse Learners In Global Environments, Jonathan Bassett

USF Tampa Graduate Theses and Dissertations

The selection of musical materials for use in the classroom is problematic. Since music educators have limited time with students, the inclusion of musical materials necessitates the perceived exclusion of other musical materials. This perception is due in part to the increasing diversity of students represented in the classroom, the cultural labeling of musical materials, the influence of multiculturalism on music education, and the influence of the Western aesthetic in music education. Since diverse groups can and do propose socially perceived valuations of these materials as critical for the inclusion of specific musical materials for use in the classroom, this …
