A Comparison Of Exhaled Breath Nitric Oxide Between Old And Young Individuals, Robert L., Gordon Jun 2004

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

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 ...

Over the last five years, there has been an increased number of computers in schools and teachers' colleges in Jamaica. In addition, recently revised national policy documents have indicated the need to infuse technology into the curricula of all schools. Despite these investments in computers, however, there has been little corresponding development in training teachers to use computers and emerging technologies as teaching learning tools.

The purposes of the study were three-fold: (a) to describe the current state of technology integration in Jamaica's teacher training programs (b) assess the extent to which teachers' college faculty and pre-service teachers perceived ...


Detection And Quantification Of Karenia Brevis Using Carbon Fixation Gene Expression Analysis, Michael Alan, Gray Jun 2004

Detection And Quantification Of Karenia Brevis Using Carbon Fixation Gene Expression Analysis, Michael Alan, Gray

Graduate Theses and Dissertations

Karenia brevis (Davis cf. Hansen & Moestrup = Gymnodinium breve) is the non-peridinin containing dinoflagellate responsible for many harmful algal blooms (red tides) in the Gulf of Mexico. These recurrent blooms can have significant negative ecological, economic, and human health impacts including fish kills, tainting of shellfish, poisoning of marine mammals, loss of tourism revenue due to beach closures, and respiratory distress and food poisoning in humans. A method for detection of Karenia brevis was developed based upon amplification of the mRNA for the plastid-encoded gene of the carbon fixing enzyme ribulose 1, 5-bisphosphate carboxylase/oxygenase (RuBisCO) large subunit (rbcL). Using sequence ...

Birth data were linked to census block groups and tracts, which were used as proxies for low birth weight. Multilevel models were used ...


Mapping Porewater Salinity With Electromagnetic And Electrical Methods In Shallow Coastal Environments, Terra Ceia, Florida, Wm Jason Greenwood Jun 2004

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

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 ...


Prediction Of Commuter Choice Behavior Using Neural Networks, Aaron L. Gregory Jun 2004

Prediction Of Commuter Choice Behavior Using Neural Networks, Aaron L. Gregory

Graduate Theses and Dissertations

In order to reduce air pollution and reduce the amount of traffic on highways in the western United States, certain states have set up worksite trip reduction programs. Employers in these states must comply with worksite trip reduction laws and submit trip reduction plans to their respective regulatory agency each year. These plans are currently evaluated manually, and are either rejected or accepted by the agency. There are two major flaws in this system; the first is the amount of time required by the agency to review a plan could be a matter of months, and the second is that ...

Microstructure And Magnetism In Ferrite-Ferroelectric Multilayer Films, Natalie A. Frey Jun 2004

Microstructure And Magnetism In Ferrite-Ferroelectric Multilayer Films, Natalie A. Frey

Graduate Theses and Dissertations

Composite magneto-dielectric materials have been investigated over the years because of their potential applications in RF and microwave devices as the dielectric constant and permeability can be individually changed in these materials. In the recent past, there is a renewed interest in systems classified as ferroelectromagnets or multiferroics, which possess simultaneous ferroelectric and magnetic ordering as well as interesting magnetoelastic phenomena. In all these ferrite-ferroelectric materials, the coupling between the permeability (μ) of the magnetically ordered phase and permittivity (e) of the ferroelectric phase make them attractive candidates for multifunctional applications.

Ba₀.₅Sr₀.₅Ti₃ (BSTO) is a ferroelectric ...

The optical and structural properties of the films were studied ...


Multi-Robot Task Allocation Using Affect, Aaron Gage Jun 2004

Multi-Robot Task Allocation Using Affect, Aaron Gage

Graduate Theses and Dissertations

Mobile robots are being used for an increasing array of tasks, from military reconnaissance to planetary exploration to urban search and rescue. As robots are deployed in increasingly complex domains, teams are called upon to perform tasks that exceed the capabilities of any particular robot. Thus, it becomes necessary for robots to cooperate, such that one robot can recruit another to jointly perform a task. Though techniques exist to allocate robots to tasks, either the communication overhead that these techniques require prevents them from scaling up to large teams, or assumptions are made that limit them to simple domains. This ...


Development Of A Solid Electrolyte For Hydrogen Production, Kiran Sampat Gaikwad Jun 2004

Development Of A Solid Electrolyte For Hydrogen Production, Kiran Sampat Gaikwad

Graduate Theses and Dissertations

Electrolytic cells convert chemical energy directly into electrical energy cleanly and efficiently. An integral component of a fuel cell and an electrolytic cell is the electrolyte, a material that conducts ions. Liquid electrolytes can be aqueous as in the phosphoric acid and alkaline fuel cells, or molten, as in the molten carbonate fuel cells. A solid electrolyte is preferable because it allows sturdier, more efficient and corrosion resistant systems to be built. The main objective of this work is to develop a solid electrolyte for hydrogen production by electrolysis of hydrogen sulfide. Barium Hydrogen Phosphate, Barium Dihydrogen Phosphate, Cesium Hydrogen ...

Institutionalized On The Margins: An Organizational History Of The Preparation Of Teachers Of College Composition, Gregory A. Giberson

Graduate Theses and Dissertations

The preparation of new college teachers of composition has been a disciplinary topic of interest as well as an institutional concern since the establishment in the late 1800s of the modern English department. In this project, I offer a critical history of the treatment of the topic of the preparation of teachers of college composition by the three most historically significant organizations to English as a discipline and Composition as a field of study within that discipline: the Modern Language Association, the National Council of Teachers of English, and the Conference on College Composition and Communication. By analyzing the treatment ...


She Fell To Her Knees And Other Stories, Karen Brown Gonzalez Jun 2004

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

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 ...

Biological Indicators Of Wetland Health: Comparing Qualitative And Quantitative Vegetation Measures With Anuran Measures, Shannon M. Gonzalez

Graduate Theses and Dissertations

Understanding wetland responses to human perturbations is essential to the effective management of Florida's surface and ground water resources. Southwest Florida Water Management District (SWFWMD) Rules (Chapter 40D-2.301(c) FAC) prohibit adverse environmental effects to wetlands, fish and wildlife caused by groundwater withdrawal. Numerous studies have documented the responses of biological attributes across taxa and regions to human disturbance. Biological assessment can provide information about ecological condition. Based on long-term monitoring conducted by the SWFWMD, the anthropogenic changes observed on the Starkey Wellfield are attributed to groundwater withdrawal. Biological indicators are species, species assemblages, or communities whose presence ...

Frequency Judgments And Recognition: Additional Evidence For Task Differences, Serena Lynn Fisher

Graduate Theses and Dissertations

Four linked experiments were run in order to understand the relationship between frequency judgment and recognition discrimination tasks. The purpose of these studies was to contrast the common-path model and recursive reminding hypothesis as explanations for the underlying principles that drive these tasks. Item-attribute variables such as printed frequency, connectivity, and set size, and an episodic variable, study frequency were manipulated. Memory for recent episodes was evaluated using recognition and frequency judgment tasks. Although all of the variables, with the exception of set size, had significant effects in both tasks, an analysis of effect sizes revealed differences between the tasks ...

Where The Palm Grows: The Ybor City Revitalization Project, Alexandra Fitos

Graduate Theses and Dissertations

Increasingly there has been a new model for inner-city redevelopment and revitalization, in which an urban area is commodified and turned into a festival market and an exclusive shopping district referred to as a shopertainment area. Ybor City in Tampa, Florida, is typical of this new model of redevelopment where urban entertainment and shopping with an active nightclub and dinning scene, entices new visitors to area, and most recently a growing residential population. The residential population that is developing is one of exclusivity and privilege, exceedingly far removed from Ybor City's humble beginnings as a company town or the ...


Behavioral And Rt-Level Estimation And Optimization Of Crosstalk In Vlsi Asics, Suvodeep Gupta Jun 2004

Behavioral And Rt-Level Estimation And Optimization Of Crosstalk In Vlsi Asics, Suvodeep Gupta

Graduate Theses and Dissertations

Signal integrity is a very critical parameter in modern digital circuits. The downscaling of technologies to enable miniaturization results in loss of signal integrity on account of crosstalk between interconnect signal lines placed very close to one another. There arises an acute need of methodologies to estimate crosstalk in interconnects and minimize it, in order to generate reliable designs. Although there exist several crosstalk estimation and optimization techniques in literature, most of these techniques operate at the layout-level of circuits. There is a dearth of techniques which tackle the crosstalk estimation and optimization problem at the behavioral and RT-levels where ...


Deterioration Process And Deck Failure Mechanism Of Florida's Precast Deck Panel Bridges, Ivan A. Gualtero Jun 2004

Deterioration Process And Deck Failure Mechanism Of Florida's Precast Deck Panel Bridges, Ivan A. Gualtero

Graduate Theses and Dissertations

During the late 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 has 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 ...


Sports And The American Sacred: What Are The Limits Of Civil Religion?, Frank Ferreri Jun 2004

Sports And The American Sacred: What Are The Limits Of Civil Religion?, Frank Ferreri

Graduate Theses and Dissertations

This thesis examines whether American civil religion, in its enactment in daily American life, is cosmological. That is, it questions whether the sacred behind American civil religion is present in the physical-material realm and not in a transcendental principle or being. It is interested in why, seemingly, what is sacred in American culture is always what is happening here and now. This is evidenced by and manifested in multiple vehicles of the sacred in American culture. These vehicles include a range of institutions from economics to politics to religion to education. They also include entities such as the mass media ...


Assessor Effects On The Evaluation Of The Wisc-Iii, Sherecce A. Fields Jun 2004

Assessor Effects On The Evaluation Of The Wisc-Iii, Sherecce A. Fields

Graduate Theses and Dissertations

There have been many theories about cultural differences found between groups on intelligence test scores. The main debate has been between those in favor of a genetic explanation versus those in favor of a more environmental one. When considering environmental influences, one explanation has been that there could be differential effects due to the assessor. Although there have been several studies that have considered this possibility, the results are inconclusive. The current study attempted to tease apart the assessor effects by focusing on biases in the assessor alone and by eliminating effects from the test taker.

The study is an ...


The Literacy Practices Of Working Class White Women, Jody Ann Fernandez Jun 2004

The Literacy Practices Of Working Class White Women, Jody Ann Fernandez

Graduate Theses and Dissertations

It is an accepted construct that literacy proficiency is vital to economic success in America. As well, research has shown that home literacy use, especially parental practices, is instrumental in the children's acquisition of literacy skills, and later, proficiency with school literacy tasks. While literacy research abounds regarding family literacy practice, especially that of low-income mothers and children, rarely is the concept of class specifically addressed as separate from race. The purpose of this study was to investigate and describe the reported home literacy practices of nine white working class women residing in a neighborhood in the Southeastern United ...

Lake Stage Fluctuation Study In West-Central Florida Using Multiple Regression Models, Jie, Gao

Graduate Theses and Dissertations

Multiple linear regression models were developed to calculate lake fluctuation that occurs between 10 percent, 50 percent, and 90 percent of the time lake surface elevation is exceeded. A total of 48 lakes were selected from Hillsborough, Pasco, Highlands and Polk counties, which were identified as natural lakes through the study the Southwest Florida Water Management District (SWFWMD) conducted in 1999 and 2002 to develop the models. "Natural lake" refers to lakes that were not impacted by ground water pumping. Among these 48 lakes, 22 lakes from Hillsborough and Pasco counties sit in the coastal lowlands area. 26 lakes from ...


Structural Diversity In Metal-Organic Nanoscale Supramolecular Architectures, Heba, Abourahma Jun 2004

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

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 ...
