The Nature Of Questioning Moves Used By Exemplary Teachers During Reading Instruction, Melinda M. Lundy

USF Tampa Graduate Theses and Dissertations

This study examines and describes the nature of questioning moves used by two exemplary fourth-grade teachers during reading instruction. Questioning moves are defined in this study as the ways in which teachers use scaffolding questions to engage students in talk about text. Another point of interest in this study was to determine how teachers perceive the influence of instructional materials on the language they use to engage students in talk about text.

This study was situated within a constructivist paradigm of inquiry and drew from the case study tradition for its design. Naturalistic methods of data collection were employed including …

Advancement And Optimization Of An Electrospray Injection Based In-Vacuum Patterning System For Macromolecular Materials, Andreas Stark

USF Tampa Graduate Theses and Dissertations

Electrospray ionization is a technique widely used in mass spectrometry. Almost every material, specifically large molecules like proteins or polymers can be ionized directly out of solution. During the ionization process molecules are not fragmented. In this work a prototype apparatus for creating three-dimensional patterns in a ultra high vacuum environment using an electrospray ion source was optimized for higher ion currents hence deposition rate by improving the core component of the apparatus, an electrodynamic ion funnel. The major improvements are a redesigned heated vacuum inlet, modified gas flow inside the ion funnel because of sealing the ion funnel against …

Identifying Patients With Cancer At Risk Of Experiencing A Fall While Hospitalized, Joann M. Heaton

USF Tampa Graduate Theses and Dissertations

Inpatient falls are the most reported incidents in the acute care setting. Symptoms associated with a diagnosis of cancer and treatment may increase risk for falls. The objectives of this study were to identify the risk factors, and the most common risk factors, of adult patients with cancer who fell while hospitalized. A retrospective, matched, case-control audit of electronic medical records and occurrence reports was conducted for 30 patients who fell and 30 patients who did not fall while under the care of the inpatient oncology unit in a community hospital. Fall subjects and controls were matched by cancer diagnosis …

The Effects Of Pre-Writing Strategy Training Guided By Computer-Based Procedural Facilitation On Esl Students’ Strategy Use, Writing Quantity, And Writing Quality, Darunee Dujsik

USF Tampa Graduate Theses and Dissertations

Pre-writing strategies are conscious thoughts, actions, or behaviors used by writers when they plan before writing. Research in second language writing suggests that specific writing strategies related to writing purposes, audience, brainstorming, and organizing ideas are teachable and have a potential to improve the quantity and quality of writing produced by English as second language (ESL) learners. This study investigated the effects of computer-based pre-writing strategy training guided by procedural facilitation (Bereiter & Scardamalia, 1987) on intermediate ESL students' writing strategy use, writing quantity, and writing quality.

A sequential mixed methods design was utilized with an initial quasi-experimental phase followed …

High-Rise Neighborhood: Rethinking Community In The Residential Tower, Benjamin Hurlbut

USF Tampa Graduate Theses and Dissertations

Within the United States, a growing sense of detachment exists. Conditions in both urban and suburban contexts have created a sense of social detachment where spaces do not exist which encourage social interaction. Without this social activity, neighbors become almost a disposable commodity as relationships never fully develop. This thesis will be an examination of environments which do and do not foster community relationships and an implementation of community into an urban multi-family residence.

A major part of the problem is the recent move to the suburbs, but urban buildings also exhibit a lack of spaces which help encourage a …

Psychometrics Of Osce Standardized Patient Measurements, Frederick R. B Stilson

USF Tampa Graduate Theses and Dissertations

This study examined the reliability and validity of scores taken from a series of four task simulations used to evaluate medical students. The four role-play exercises represented two different cases or scripts, yielding two pairs of exercises that are considered alternate forms. The design allowed examining what is essentially the ceiling for reliability and validity of ratings taken in such role plays. A multitrait-multimethod (MTMM) matrix was computed with exercises as methods and competencies (history taking, clinical skills, and communication) as traits. The results within alternate forms (within cases) were then used as a baseline to evaluate the reliability and …

Facilitating Communication And Effective Interpersonal Relationships At Work: A Theoretical Model Of Socio-Affective Competence, Adam C. Bandelli

USF Tampa Graduate Theses and Dissertations

The research reported here provides an introduction to a theoretical model of socio-affective competence. This conceptual model of social effectiveness consists of four competencies that are related to the development of effective interpersonal relationships in the workplace. These competencies include: establishing rapport, promoting acceptance of differences, developing trust and cultivating charismatic influence. The socio-affective competence model was formulated in an attempt to integrate research on social and emotional skills that have been linked to performance in organizations. The current research proposed the model and defined its competency areas, designed a socio-affective competence situational judgment test (SAC-SJT), identified the variables that …

The Role Of Occupational Values And Support In Career Choice: An Emphasis On Women In Science, Heather Meikle

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine how occupational values and social support for career pursuits influenced career choice, with a specific focus on women in science, technology, engineering, or mathematics (STEM). A sample of 62 college graduates participated in telephone interviews that addressed gender differences in seven occupational values and three sources of social support. Results showed that differences in occupational values differ by both gender and between individuals in STEM and non-STEM careers. The strength of STEM values better predicted a career in STEM than did gender. Finally, women in STEM received the least amount of social …

Organizational Communication And Change: A Case Study On The Implementation Of An Innovation At A Florida Medical Facility, Erika G. Llenza

USF Tampa Graduate Theses and Dissertations

This study examined how employees at a Florida medical facility felt regarding the upcoming change to a paperless system and whether a training program administered by the organization was effective in reducing anxiety, increasing understanding of the need for the change, increasing employee confidence using the new computer system, changing employee perceptions of the new system, and helping employees view the change as an organizational improvement. The results indicated that the training program marginally reduced anxiety, but did not significantly increase user confidence or understanding of the need for the change. While participants viewed the change as an organizational improvement, …

Teaching Functional Skills To Individuals With Developmental Disabilities Using Video Prompting, Julie A. Horn

USF Tampa Graduate Theses and Dissertations

Because many individuals with developmental disabilities prefer to be as independent as possible, strategies need to be developed to teach them functional skills. Video prompting is a fairly new technology, in which a person learns to engage in a complex behavior by viewing steps of a task analysis on video. The steps are broken down so that the task is more manageable for the individual. The present study evaluated how many steps needed to be presented in the video model for the learner to acquire a functional skill. Three individuals between the ages of 17 and 29 and diagnosed with …

Stress Analysis And Mechanical Characterization Of Thin Films For Microelectronics And Mems Applications, Patrick Waters

USF Tampa Graduate Theses and Dissertations

Thin films are used for a variety of applications, which can include electronic devices, optical coatings and decorative parts. They are used for their physical, electrical, magnetic, optical and mechanical properties, and many times these properties are required simultaneously. Obtaining these desired properties starts with the deposition process and they are verified by a number of analysis techniques after deposition. A DC magnetron sputter system was used here to deposit tungsten films, with film thickness and residual stress uniformity being of primary interest. The film thickness was measured to vary by up to 45 % from the center to outer …

A Monte Carlo Approach For Exploring The Generalizability Of Performance Standards, James Thomas Coraggio

USF Tampa Graduate Theses and Dissertations

While each phase of the test development process is crucial to the validity of the examination, one phase tends to stand out among the others: the standard setting process. The standard setting process is a time-consuming and expensive endeavor. While it has received the most attention in the literature among any of the technical issues related to criterion-referenced measurement, little research attention has been given to generalizing the resulting performance standards. This procedure has the potential to improve the standard setting process by limiting the number of items rated and the number of individual rater decisions. The ability to generalize …

Manatee Sound Localization: Performance Abilities, Interaural Level Cues, And Usage Of Auditory Evoked Potential Techniques To Determine Sound Conduction Pathways, Debborah Colbert

USF Tampa Graduate Theses and Dissertations

Three experiments investigated the ability and means by which Florida manatees determine sound source directionality. An eight-choice discrimination paradigm determined the sound localization abilities of two manatees within a 360° array of speakers. Five conditions were tested including a 3,000 and 200 ms, 95 dB, 0.2-24 kHz signal, a 3,000 ms, 80 dB, 18-24 kHz signal, a 3000 ms, 110 dB, 0.2-1.5 kHz signal and a 200 ms, 101 dB, 4 kHz tonal signal. A sixth condition attenuated the level of the 3,000 ms, 95 dB, 0.2-24 kHz signal in 3 dB increments until accuracy reached 75%. Subjects performed above …

Boundary And Longing: Narrative Modes In Mary Shelley’S Frankenstein And The Last Man, Marie Hendry

USF Tampa Graduate Theses and Dissertations

Boundary and desire surround the relationships in Mary Shelley's Frankenstein and The Last Man. The narrative modes of Captain Robert Walton relate his separation to the rest of the world and his need for companionship. Yet, not any companionship will satisfy his longing for connection with a human being; his search revolves around the need of common understanding. This further separates the character of Lionel in The Last Man from humanity in that he is unable to find anyone left on earth after a series of plague, war, and atmospheric anomalies apparently wipe out the human race. His survival …

(Re)Defining Relationships In A Mediated Context: Graduate Student Use Of Synchronous Computer-Mediated Communication, Michael P. Nicholas

USF Tampa Graduate Theses and Dissertations

This study consists of qualitative interviews with 8 graduate students about the use of synchronous computer-mediated communication (SCMC), or instant message (IM), programs in their interpersonal relationships. Participants were interviewed twice, once via an instant message program and once in a face-to-face setting. They were asked about their frequency of use, their use of multi-tasking, and the types of conversations they have via IM. Results of the interviews are discussed, with a concentration on the paradoxical nature of IM communication as impersonal, but at the same time, conducive to personal disclosure and intimacy.

Black Beauty As Antebellum Slave Narrative, Bonnie L. Blossom

USF Tampa Graduate Theses and Dissertations

Published in November 1877, Black Beauty is one of the most popular and enduring works of the nineteenth and twentieth centuries. The book, in which the eponymous narrator relates his life's story, sold well following its publication in England and in the United States; by 1985, sales were estimated at over forty million. While usually regarded as entertaining, Black Beauty has a strong crusading purpose: Anna Sewell herself said she wrote to improve the treatment of horses.

This study springs from an intuitive notion. While reading the 1845 Narrative of the Life of Frederick Douglass, I could not shake …

Effects Of Bilingualism On Speech Recognition Performance In Noise, Mitzarie A. Carlo

USF Tampa Graduate Theses and Dissertations

This study examined the effects of bilingualism on speech recognition in noise performance of young normal-hearing Spanish-English bilinguals across several signal-to-noise ratios (SNR). The estimated signal-to-noise ratio needed for 50% correct recognition performance obtained for bilingual listeners was compared to young normal-hearing monolingual listeners of both English and Spanish. The estimated mean SNR needed for 50% correct recognition was significantly higher (i.e., poorer) for the bilingual than for the monolingual English listeners. The Spanish language performance of the bilingual listeners did not significantly differ from that of the monolingual Spanish listeners. The bilinguals were then divided into subgroups based on …

Creative City And Fields Of Cultural Production: Ethnographic Perspectives Of “The Arts” In Tampa, James Kuzin

USF Tampa Graduate Theses and Dissertations

Stimulated by the economic theories of Richard Florida (2005), the City of Tampa established the Office of Creative Industries (OCI) to oversee efforts to strengthen the presence and visibility of "the arts." This thesis presents ethnographic research focused on practices, and perspectives among members of the OCI's service population. From July 2006 to July 2007, I conducted fieldwork among a diverse group of stakeholders possessing a unique connection to the aims of the OCI. The central problem addressed in this research looks at the degree to which cultural change occurs from participatory, grass-roots initiatives, rather than ones emanating from "the …

Garden Doors: Tempting The Virtuous Heroine In Clarissa And Betsy Thoughtless, Jamie Kinsley

USF Tampa Graduate Theses and Dissertations

Gardens in Eliza Haywood's The History of Miss Betsy Thoughtless, and Samuel Richardson's Clarissa, or a History of a Young Lady provide a place for the characters to gain knowledge; but without preparation to receive this knowledge - if restrained behind the veil of decorum - they come to harm, rather than constructive awareness. A fine line exists between innocence and experience in these works. The ways in which the characters negotiate this line illustrates the complexities involved in the eighteenth-century understanding of virtue and how society attempted to mediate this issue. This negotiation can be seen largely in …

Mathematical Modeling And Analysis Of Options With Jump-Diffusion Volatility, Irena Andreevska

USF Tampa Graduate Theses and Dissertations

Several existing pricing models of financial derivatives as well as the effects of volatility risk are analyzed. A new option pricing model is proposed which assumes that stock price follows a diffusion process with square-root stochastic volatility. The volatility itself is mean-reverting and driven by both diffusion and compound Poisson process. These assumptions better reflect the randomness and the jumps that are readily apparent when the historical volatility data of any risky asset is graphed. The European option price is modeled by a homogeneous linear second-order partial differential equation with variable coefficients. The case of underlying assets that pay continuous …

Capitalism, Consumerism, And Individualism: Investigating The Rhetoric Of The Secret, Carolina Fernandez

USF Tampa Graduate Theses and Dissertations

I am investigating a New Age spiritual movement called the Law of Attraction that has been the source of recent media attention due to the recent publication of a self-help book called The Secret. The book investigates this phenomenon, which is a theory that takes positive thinking to the extreme. The theory states that reality can be literally manifested through one's thoughts. I am interested in this trend because it supports consumerist values, entrepreneurship, and self-actualization while using socialist rhetoric to promote capitalist values. I am also interested in the implications that this rhetoric holds for women and marginalized groups. …

“Pleasant Episodes” Of Gastronomy: Food And Drink In F. Scott Fitzgerald’S The Beautiful And Damned, Melissa Faith Dullaghan

USF Tampa Graduate Theses and Dissertations

This thesis explores the motif of gastronomy in Fitzgerald's critically undertreated second novel, The Beautiful and Damned. Within the discussion of the leisure class, Fitzgerald scholars often focus on Jay Gatsby's parties, but they seem to neglect Anthony Patch and company's fancy for food and drink in Ivy League supper clubs of Manhattan, vaudeville theaters, and houses of languor in Upstate New York. Building upon George J. Searles's article "The Symbolic Function of Food and Eating in F. Scott Fitzgerald's The Beautiful and Damned," this thesis examines the meaning of Fitzgerald's pervasive "prandial allusions" and character psychology with …

An Evaluation Of Conduit Conceptualizations And Model Performance, Melissa Estelle Hill

USF Tampa Graduate Theses and Dissertations

The karst research community has known that traditional numerical groundwater flow codes ignore the non-Darcian, dual-permeability components of flow that can occur in karst aquifers. In this study, the potential limitations of using such tools are quantified by evaluating the relative performances of 3 groundwater flow models at a test-site near Weeki Wachee, Florida, in the dual-permeability Upper Floridan aquifer. MODFLOW-2005 and MODFLOW-2005 Conduit Flow Process (CFP), a Darcian/non-Darcian, dual-permeability groundwater flow code recently developed by the U.S. Geological Survey, are used in this study.

A monitoring program consisting of discharge measurements and high frequency data from 2 springs and …

Heat Fluxes In Tampa Bay, Florida, Kristin L. Sopkin

USF Tampa Graduate Theses and Dissertations

The Meyers et al. (2007) Tampa Bay Model produces water level and three-dimensional current and salinity fields for Tampa Bay. It is capable of computing temperature but is presently run without active thermodynamics. Variations in water temperature are driven by heat exchange at the water-atmosphere boundary and advective heat flux at the mouth of the bay. The net heat exchange surface boundary condition is required for computations of three-dimensional temperature fields. Components of the surface heat budget were measured or derived at an observational tower in Middle Tampa Bay. Net heat exchange at the surface of Tampa Bay was computed …

“Smole Trifeles“: The Itinerant In British North America, David Michael Davisson

USF Tampa Graduate Theses and Dissertations

The earliest attempt to form a confederation among the British colonies in North America occurred with the creation New England confederation in 1643. For the next one hundred thirty-four years various attempts would be made to organize British America colonies into a confederacy. "Smole Trifeles": The Itinerant in British America moves beyond traditional histories which analyze how the social and political elite worked to bring the colonies together. This work focuses on the peddlers, the hawkers, petty chapmen, and the itinerant preachers who roamed the primitive roads and highways of early America. These wanderers knit together a nation and helped …

Major League Baseball Franchises And Their Minor League Players, Maintaining A Relationship On And Off The Field, Michelle Keating

USF Tampa Graduate Theses and Dissertations

In today's professional arena, organized sports have grown to become institutionalized and highly organized through corporations in a multi-billion dollar industry. Through the use of in depth interviews completed online, this study investigated the role franchise communication plays in the development of nineteen minor league players' relationships within the Major League Baseball (MLB) sports industry. Results found that players feel their organizations disproportionately help some players achieve success over others and withhold information. As players, they felt they have a limited voice regarding the direction of their careers. Despite a difficult working environment, the players' desire to achieve success and …

The Role Of Rala And Ralb In Cancer, Samuel C. Falsetti

USF Tampa Graduate Theses and Dissertations

Ras genes are frequently mutated in human cancers and present compelling targets for therapeutic intervention. While previous attempts to directly inhibit oncogenic Ras function have largely been unsuccessful use of targeted agents to inhibit the three primary oncogenic pathways activated by mutated Ras: RalGEF-Ral, PI3K-Akt and Raf- MEK-Erk, is an area of intense investigation. Here, we describe the ability of a novel pharmacological inhibitor of geranylgeranyltransferase I, GGTI-2417, to inhibit Ral prenylation and localization. We further used a Ral rescue system to selectively preserve RalA and RalB function and localization during GGTI-2417 treatment and determine the precise roles for inhibition …

Advances In Magnetic Resonance Electrical Impedance Mammography, Nataliya Kovalchuk

USF Tampa Graduate Theses and Dissertations

Magnetic Resonance Electrical Impedance Mammography (MREIM) is a new imaging technique under development by Wollin Ventures, Inc. in conjunction with the H. Lee Moffitt Cancer Center & Research Institute. MREIM addresses the problem of low specificity of magnetic resonance mammography and high false-positive rates, which lead to unnecessary biopsies. Because cancerous tissue has a higher electrical conductivity than benign tissue, it may serve as a biomarker for differentiation between malignant and benign lesions. The MREIM principle is based on measuring both magnetic resonance and electric properties of the breast by adding a quasi-steady-state electric field to the standard magnetic resonance …

Brca1 185delag Mutant Protein, Brat, Amplifies Caspase-Mediated Apoptosis And Maspin Expression In Ovarian Cells, Joshua D. O'Donnell

USF Tampa Graduate Theses and Dissertations

Ovarian cancer is a deadly disease that kills an estimated 15,000 women annually in the United States. It is estimated that approximately 10% of ovarian cancers are due to familial inheritance. The most commonly mutated genes in familial ovarian cancer are BRCA1 and BRCA2. It has been reported that cells carrying the BRCA1 185delAG mutation undergo an enhanced caspase-3 mediated apoptotic response. Here, we report on the transfection of cDNA coding for the putative truncated protein product of the BRCA1 185delAG mutant gene into BRCA1 wild-type human immortalized ovarian surface epithelial (IOSE) cells and ovarian cancer cells. Cells transfected …
