Three Essays On Analytical Models To Improve Early Detection Of Cancer, Chaitra Gopalappa

USF Tampa Graduate Theses and Dissertations

Development of approaches for early detection of cancer requires a comprehensive understanding of the cellular functions that lead to cancer, as well as implementing strategies for population-wide early detection. Cell functions are supported by proteins that are produced by active or expressed genes. Identifying cancer biomarkers, i.e., the genes that are expressed and the corresponding proteins present only in a cancer state of the cell, can lead to its use for early detection of cancer and for developing drugs. There are approximately 30,000 genes in the human genome producing over 500,000 proteins, thereby posing significant analytical challenges in linking …

Exergy Modeling To Compare Engineered Products To Biological Systems For Sustainable Design, Richard D. Stokes Jr.

USF Tampa Graduate Theses and Dissertations

An ambitious and novel approach to engineering design and sustainability has been taken to explore the potential of drawing parallels between mechanical and biological systems for the possible development of sustainable engineering design metrics using a thermodynamic model. This approach looks to biology. Natural selection has given biological beings and processes high exergetic efficiencies, even while being only 30-40% energy efficient on the cell level. This energy inefficiency, resulting in a release of heat, can then be used to aid in driving other biochemical processes. The Gibbs free energy becomes more negative proportionally with an increase in temperature, resulting in …

Evaluating Knowledge And Attitudes Of Undergraduate Nursing Students Regarding Pain Management, Jessica Latchman

USF Tampa Graduate Theses and Dissertations

Unmanaged pain is a widespread problem that many cancer patients face on a daily basis. Cancer pain, which can either be caused by complications due to the disease process itself or from treatment measures used, has devastating effects on the quality of life for these patients and their caregivers. This study examined the knowledge and attitudes of undergraduate students regarding pain management.

The sample in this study consisted of 41 undergraduate students at the University of South Florida College of Nursing. The students sampled were predominantly white, (n=30), female (n=37), seniors (n=41) taking Leadership and Management in Nursing. After volunteering …

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 …

Illusion In Troilus And Cressida, Edward Janz

USF Tampa Graduate Theses and Dissertations

This thesis is an examination of Shakespeare's 1603 satire Troilus and Cressida that looks at illusion and the value given to it by means of war, Helen of Troy, and ultimately the two lovers themselves. Although it is depressingly obvious throughout the drama that life is an illusion, it is also obvious that there is a need for that illusion, and an equally profound necessity to have the illusion debunked.

The first part of the thesis examines the impact of war on Troy. This part concentrates on the myth of the hero, who like Falstaff presents himself to the world …

Re-Tooling An American Metropolis, Robert Shawn Hott

USF Tampa Graduate Theses and Dissertations

Re-tool:

v.tr. re-tooled, re-tooling, re-tools

1. To fit out (a factory, for example) with a new set of machinery and tools for making a different product.

2. To revise and reorganize, especially for the purpose of updating or improving.

The American ideals inherent in the suburbs are the promise of space, affordability, convenience, and traditional family life; conversely the public realms of the suburban typology become disconnected from each other as well as the larger city. The Generic City condition in which the periphery is no longer captivated by the center from which it was created is pervasive in the …

Carbon Dioxide Capture From Fossil Fuel Power Plants Using Dolomite, Drupatie Latchman

USF Tampa Graduate Theses and Dissertations

The main objective of this research is to develop a simple and cost effective separation method that captures carbon dioxide from power plant flue gas, as a pure stream that can be stored using regenerable dolomite (calcium magnesium carbonate) as the sorbent. The developed dolomite sorbent was evaluated for carbon dioxide capture capacity using muti-cycle tests of cyclical carbonation/calcination experiments in the thermogravimetric analyzer (TGA) model SDT 600. The variables controlled in the experiment were weight of calcium oxide and sintering time of the sample. The dolomite materials investigated were from two sources Alfa Aesar and Specialty Minerals. The prepared …

“An Indescribable Sound” In William Faulkner’S The Sound And The Fury, Lynn Ramsey

USF Tampa Graduate Theses and Dissertations

The Sound and the Fury is a noisy book. Through the audible, the barely audible, and the silence, William Faulkner supports his narrative design with sound beyond dialog to inform and inflect the destabilizing narrative voices. This essay explores Faulkner's use of the sound and noise of the novel as another narrative voice. Faulkner's rich use of sound as a recurring motif, almost a persona or narrator itself, functions not merely to animate the action, the characters, and the title; it also speaks in the "hush" and the freighted "stiffly sibilant" whispers of those who dare not speak, or are …

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 …

Shamanism, Spiritual Transformation And The Ethical Obligations Of The Dying Person: A Narrative Approach, Ellen W. Klein

USF Tampa Graduate Theses and Dissertations

The person experiencing chronic or protracted illness is confronted with a complex array of physical, emotional and spiritual trials. This thesis explores how chronic illness can be viewed through the lens of the shamanic experience of dismemberment and re-memberment and shows how clinical, narrative, and relational models on their own are insufficient to speak meaningfully to illness experiences, but the integration of aspects of each of these models when coupled with shamanic initiation experience creates an innovative model for patients and those with whom they are in relationship.

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 …

Neuroprotection With Anesthetics In Two Models Of Cerebral Ischemia, Rafael Eduardo Chaparro Buitrago

USF Tampa Graduate Theses and Dissertations

Neuroprotection with anesthetics has been studied for many decades; important advances in this field have modified the way Anesthesiologists treat patients in the operating room. Animal models have played an important role in the study of ischemia in the operating room. Recent studies have demonstrated that the effect of anesthetics seems to be different in different animal models. We decided to evaluate anesthetics in a well-known model of cerebral ischemia and also in hypotensive models designed by us. We used a model of cerebral ischemia (MCAO) to test anesthetics neuroprotective effect in a two-week period. Then, we used a model …

Is There An "Innocent Female Victim" Effect In Capital Punishment Sentencing?, Amelia Lane Kirkland

USF Tampa Graduate Theses and Dissertations

Disparities in the administration of capital punishment are a prominent social and political issue. While the focus of death penalty disparity research initially lay with the defendant and how the defendant’s race or ethnicity affects sentencing outcomes, only marginal support for offender effects has been found. A consistent finding, however, is that victim race has a significant effect on capital sentencing outcomes. Recent examinations of the joint effects of victim characteristics indicate that victim gender also has some influence in capital sentencing decisions. While these prior studies have examined the interactive effects of victim gender and victim race the current …

Who Owns Disability? An Investigation Into The Politics Of Representation, Shelby Forbes

USF Tampa Graduate Theses and Dissertations

In this thesis, I show how a community of professionals providing equine therapy to individuals with disabilities discursively make sense of their enterprise. A market metaphor illustrates how disability is constructed as the capital sustaining the livelihood of their industry. Disability is a problem-centered concept. It is generally conceptualized according to a medical model which locates disability within the individual, as opposed to understanding it in a sociological sense which accounts for structural, cultural, and communicative factors. Therapy, on the other hand, is problem-determined-it needs to explicitly determine a problem to be treated in order to sustain itself as an …

Seismic And Geodetic Investigation Of The 1996-1998 Earthquake Swarm At Strandline Lake, Alaska, Wayne Walter Kilgore

USF Tampa Graduate Theses and Dissertations

Microearthquake (< M3.0) swarms occur frequently in volcanic environments, but do not always culminate in an eruption. Such non-eruptive swarms may be caused by stresses induced by magma intrusion, hydrothermal fluid circulation, or regional tectonic processes, such as slow-slip earthquakes. Strandline Lake, located 30 km northeast of Mount Spurr volcano in south-central Alaska, experienced an intense earthquake swarm between August 1996 and August 1998. The Alaska Volcano Observatory (AVO) catalog indicates that a total of 2,999 earthquakes were detected during the swarm period, with a maximum magnitude of M_w 3.1 and a depth range of 0-30 km below sea level (with the majority of catalog hypocenters located between 5-10 km BSL). The cumulative seismic moment of the swarm was 2.03e¹⁵ N-m, equivalent to a cumulative magnitude of M_w 4.2. Because of the swarm's distance from the nearest Holocene volcanic vent, seismic monitoring was poor and gas and GPS data do not exist for the swarm period. However, combined waveforms from a dense seismic network on Mount Spurr and from several regional seismic stations allow reanalysis of the swarm earthquakes. I first developed a new …

Measurement Of Community And Laboratory-Generated Airborne Particulates Using A New Sampling Method, Laura Farina

USF Tampa Graduate Theses and Dissertations

This project resulted from an alleged dust problem affecting the residents in a Florida community. The residents claimed that there were elevated dust levels caused by a rock quarry adjacent to their homes. The purpose of this work was to assess total particulate, respirable particulate, and the coarse content of the sampled particles through traditional NIOSH methods, and using a new, real-time instrument known as the EPAM 5000. Data from the EPAM and NIOSH methods were compared to the EPA's particulate matter standards and the OSHA permissible exposure limits for total and respirable dust. Dust levels using the NIOSH methods …

Factors Affecting The Process Of Clinical Decision-Making In Pediatric Pain Management By Emergency Department Nurses, Teresa A. Russo

USF Tampa Graduate Theses and Dissertations

The purpose of this mixed methods study was to describe the cognitive processes/knowledge sources used by Emergency Department (ED) nurses in decision-making activities regarding triage and pediatric pain assessment and management. Deficiencies persist in ED pediatric pain assessment, and management methods or approaches that might help resolve these deficiencies have not been identified previously. Methodology triangulation with sequential use of qualitative- quantitative methods provided a rich description of knowledge sources and cognitive processes used by ED nurses relative to pediatric pain assessment decisions. Based on qualitative results, a set of vignettes was developed to assess ED nurses. Data analysis using …

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.

The Effects Of Physical Distinctiveness And Word Commonness On Brain Waves And Subsequent Memory: An Erp Study, Siri-Maria Kamp

USF Tampa Graduate Theses and Dissertations

Words that deviate in their physical characteristics from their surrounding lead to enhanced recall memory, a pattern known as the Von Restorff effect. Furthermore, common (high frequency; HF) words are more likely to be recalled than uncommon (low frequency; LF) words when they occur in pure lists, while this pattern is reversed in mixed lists of both HF and LF words. This study investigated whether the Von Restorff effect and the reversal of word frequency effects in mixed lists, which may both be explained by enhanced perceived distinctiveness, are associated with common underlying brain processes. Event-related potentials (ERPs) …

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 …

Extending The Principal Stratification Method To Multi-Level Randomized Trials, Jing Guo

USF Tampa Graduate Theses and Dissertations

The Principal Stratification method estimates a causal intervention effect by taking account of subjects' differences in participation, adherence or compliance. The current Principal Stratification method has been mostly used in randomized intervention trials with randomization at a single (individual) level with subjects who were randomly assigned to either intervention or control condition. However, randomized intervention trials have been conducted at group level instead of individual level in many scientific fields. This is so called "two-level randomization", where randomization is conducted at a group (second) level, above an individual level but outcome is often observed at individual level within each group. …

The Female Colonizer And Othered Woman In Isak Dinesen's Out Of Africa, Jean Rhys's Wide Sargasso Sea, Tayeb Salih's Season Of Migration To The North, And Paule Marshall's The Chosen Place, The Timeless People, Lindsay L. Sloan

USF Tampa Graduate Theses and Dissertations

The central issue of this thesis is the complicated relationship between the colonized individual and the constitutive as well as emblematic female colonizer in Isak Dinesen's Out of Africa, Jean Rhys's Wide Sargasso Sea, Tayeb Salih's Season of Migration to the North, and Paule Marshall's The Chosen Place, The Timeless People. Each of these novels displays colonization by a female (or females) and relates back to historical colonialism, but each characterizes the relationship between the oppressors and oppressed differently. Dinesen's and Rhys's works stem from historical colonization in which European colonizers conquered and ruled other territories; …
