Narratives And Sensemaking In The New Corporate University: The Socialization Of First Year Communication Faculty, Andrew F. Herrmann

USF Tampa Graduate Theses and Dissertations

I examined what brand new Ph.D.s in Communication experience when they start their first, entry-level, tenure-track assistant professor position at a new university. Through the lens of scocial construction, I review vocational and organizational socialization, individual agency by newcomers, academic socialization processes, and the concept of the academic career in the current climate of university change and transformation. Then, I present the method of research, including the population and sampling method, and rationales for utilizing a narrative approach, interactive interviewing, and autoethnographic writing. After presenting the participants' narratives, I revisit both within- and between-case issues, beginning with socialization from the …

Teacher Efficacy And Student Achievement In Ninth And Tenth Grade Reading: A Multilevel Analysis, Anete Vasquez

USF Tampa Graduate Theses and Dissertations

More than 8 million of America's middle and high school students are struggling readers. Two-thirds of all eighth graders read below grade level, and the reading scores of high school students have not improved since 1974. Low literacy levels affect learning in all subject areas and impede student opportunity for future success. The No Child Left Behind Act of 2001 and the accountability measures associated with the Act have heightened public awareness of the deficiency in adolescent literacy. School districts are choosing to respond in one of two ways. Some school districts are opting to invest in teacher-proof curricula that …

Utilitarian Approaches For Multi-Metric Optimization In Vlsi Circuit Design And Spatial Clustering, Upavan Gupta

USF Tampa Graduate Theses and Dissertations

In the field of VLSI circuit optimization, the scaling of semiconductor devices has led to the miniaturization of the feature sizes resulting in a significant increase in the integration density and size of the circuits. At the nanometer level, due to the effects of manufacturing process variations, the design optimization process has transitioned from the deterministic domain to the stochastic domain, and the inter-relationships among the specification parameters like delay, power, reliability, noise and area have become more intricate. New methods are required to examine these metrics in a unified manner, thus necessitating the need for multi-metric optimization. The optimization …

The Effects Of Depressed Mood On Academic Outcomes In Adolescents And Young Adults, Robert Christopher Jones

USF Tampa Graduate Theses and Dissertations

The following dissertation investigates the relationship between depressed mood and academic performance (measured in terms of grade point average) in U.S. middle and high schools.

Utilizing data from AddHealth, the dissertation establishes Ordinary Least Squares, Two-Stage Least Squares (2SLS), and individual and sibling fixed effect regressions that attempt to control for confounding factors, including student motivation, personality characteristics, and parental inputs that are unobserved but may influence both mental health and achievement.

Study findings indicate that students who report feeling depressed do not perform as well academically as non-depressed students. Additionally, the degree of GPA impact increases with the severity …

Growth And Characterization Of Nanocrystalline Diamond Films For Microelectronics And Microelectromechanical Systems, Sathyaharish Jeedigunta

USF Tampa Graduate Theses and Dissertations

Diamond is widely known for its extraordinary properties, such as high thermal conductivity, energy bandgap and high material hardness and durability making it a very attractive material for microelectronic and mechanical applications. Synthetic diamonds produced by chemical vapor deposition (CVD) methods retain most of the properties of natural diamond. Within this class of material, nanocrystalline diamond (NCD) is being developed for microelectronic and microelectromechanical systems (MEMS) applications. During this research, intrinsic and doped NCD films were grown by the microwave plasma enhanced chemical vapor deposition (MPECVD) method using CH₄/Ar/H₂ gas mixture and CH₄/Ar/N₂ gas …

Yeats, Eliot, And Apocalyptic Poetry, Nancy Helen Fletcher

USF Tampa Graduate Theses and Dissertations

Yeats and Eliot merit comparison because they wrote poetry that has been described as apocalyptic in the same historical period and in the same general geographic area but described entirely different visions. These particular works of Yeats and Eliot are appropriate because they represent two widely varying viewpoints on the causes, nature and desirability of what each author felt would be the coming apocalypse. Therefore, more can be learned by comparing the very different outlooks of the poems than by considering each poem separately.

Yeats sees humanity as both the victim and the beneficiary of a series of inescapable historical …

On A Conjecture Involving Fermat's Little Theorem, John Clark

USF Tampa Graduate Theses and Dissertations

Using Fermat’s Little Theorem, it can be shown that Σ^m_i=1 i ^m−1 ≡ −1 (mod m) if m is prime. It has been conjectured that the converse is true as well. Namely, that Σ^m_i=1 i ^m−1 ≡ −1 (mod m) only if m is prime. We shall present some necessary and sufficient conditions for the conjecture to hold, and we will demonstrate that no counterexample exists for m ≤ 10¹² .

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 …

Study Of Fpga Implementation Of Entropy Norm Computation For Ip Data Streams, Subramanya Nagalakshmi

USF Tampa Graduate Theses and Dissertations

Recent literature has reported the use of entropy measurements for anomaly detection purposes in IP data streams. Space efficient randomized algorithms for estimating entropy of data streams are available in the literature. However no hardware implementation of these algorithms is available. The main challenge to software implementation for IP data streams has been in storing large volumes of data, along with, the requirement of high speed at which they have to be analyzed. In this thesis, a recent randomized algorithm available in the literature is analyzed for hardware implementation. Software/hardware simulations indicate it is possible to implement a large portion …

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 …

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 …

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. …

Monitoring of 40 sites throughout the Florida Keys National Marine Sanctuary has undertaken a multiple-parameter approach to assess spatial and temporal changes in the status of the ecosystem. The objectives of the present study consist of the following:

In chapter one, we review past coral reef studies; emphasis is placed on recent studies on the stony corals of reefs in the lower Florida Keys. We also review the economic impact of coral reefs on the state of Florida. In chapter two, we identify the …

Micro-Autoradiographic Fusion Tomography, James Merker

USF Tampa Graduate Theses and Dissertations

Two-dimensional (2-D) micro-autoradiography is typically used to identify the location of a radio-labeled ligand bound to a cellular target in tissue sections. Data, such as a histological image, combined with the autoradiographic data provide a spatial relationship of the radiolabel to cellular structures. However, the disadvantage of 2-D imaging is that it only provides a local distribution of the radiolabel within a tissue slice, and not a volumetric regional distribution in the structure of interest. The development of 3-D autoradiographic/histological visualizations would provide important information not otherwise apparent, such as the ability to visualize the distribution of the labeled agents …

The Influence Of Ph On Nucleation, Solubility And Structure Of Lysozyme Protein Crystals, Marc C. Apgar

USF Tampa Graduate Theses and Dissertations

X-ray diffraction from protein crystals remains the most reliable way to determine the molecular structure of proteins, and how this structure relates to biological function. However, we still lack the ability to predict solution conditions that support the nucleation and growth of high-quality protein crystals for X-ray diffraction studies. The overall goal of this thesis is two-fold: (a) determine the nucleation behavior and solubilities for lysozyme crystals with two distinct crystal structures (orthorhombic vs. tetragonal) and (b) investigate whether these changes in crystal habit and crystal solubility correlate with any discontinuities in the liquid-liquid phase boundary of lysozyme that occurs …

Studies Of The Mechanics And Structure Of Shallow Magmatic Plumbing Systems, Mikel Díez

USF Tampa Graduate Theses and Dissertations

Volcanic activity, and the resultant deposits and structures at the Earth's surface, are the outcome of the inner workings of underground magmatic plumbing systems. These systems, essentially, consist of magma reservoirs which supply magma to the surface through volcanic conduits feeding volcanic eruptions. The mechanics and structure of plumbing systems remain largely unknown due to the obvious challenges involved in inferring volcanic processes occurring underground from observations at the surface. Nevertheless, volcanologists are beginning to gain a deeper understanding of the workings and architecture of magmatic plumbing systems from geophysical observations on active volcanoes, as well as from geological studies …

“To Know Where I Have Got To”: The Postmodern Chronotope In Beckett’S Malone Dies And Coetzee’S Foe, Brian J. Mcallister

USF Tampa Graduate Theses and Dissertations

This study addresses two works of fiction--Samuel Beckett's Malone Dies and J. M. Coetzee's Foe--and is separated into two chapters. The first chapter analyzes the indeterminate nature of postmodern space within the two novels as related to M. M. Bakhtin's idea of the chronotope found in his work The Dialogic Imagination. The second chapter addresses the self-reflexive creation of this postmodern space within each novel's hypodiegetic narratives and discussions of narrative creation within each respective diegetic narratives.

In each novel, characters as authors create or discuss "inner" narratives that reflect upon the way chronotopes are created in fiction …

Forecasting Models For Economic And Environmental Applications, Shou Hsing Shih

USF Tampa Graduate Theses and Dissertations

The object of the present study is to introduce three analytical time series models for the purpose of developing more effective economic and environmental forecasting models, among others. Given a stochastic realization, stationary or nonstationary in nature, one can utilize exciting methodology to develop an autoregressive, moving average or a combination of both for short and long term forecasting. In the present study we analytically modify the stochastic realization utilizing (a) a k-th moving average, (b) a k-th weighted moving average and (c) a k-th exponential weighted moving average processes. Thus, we proceed in developing the appropriate …

The Benefits Of Interleaving Different Kinds Of Mathematics Practice Problems, Kelli M. Taylor

USF Tampa Graduate Theses and Dissertations

In most mathematics textbooks, virtually all of the problems in each set of practice problems, or in each practice set, relate to the immediately preceding lesson - an arrangement described here as the standard format of practice. Alternatively, the problems within a shuffled practice set are drawn from numerous lessons. With the shuffled format, each practice set has two distinguishing features: within-session spacing, in which problems of the same kind appearing in a single practice set are separated by some period of time, and mixed practice, in which different types of problems are interleaved. Although previous studies …

Lagrange Interpolation On Leja Points, Rodney Taylor

USF Tampa Graduate Theses and Dissertations

In this dissertation we investigate Lagrange interpolation. Our first result will deal with a hierarchy of interpolation schemes. Specifically, we will show that given a triangular array of points in a regular compact set K, such that the corresponding Lebesgue constants are subexponential, one always has the uniform convergence of L_n(f) to f for all functions analytic on K. We will then show that uniform convergence of L_n(f) to f for all analytic functions f is equivalent to the fact that the probability measures γ_n = 1/n Σ^{n …}

Biogeochemical Cycling Of Arsenic In The Marine Shallow-Water Hydrothermal System Of Tutum Bay, Ambitle Island, Papua New Guinea, Roy E. Price

USF Tampa Graduate Theses and Dissertations

The marine shallow-water hydrothermal vent system of Tutum Bay, Ambitle Island, PNG discharges hot, acidic, arsenic-rich, chemically reduced fluid into cool, alkaline, oxygenated seawater. Gradients in temperature, pH, total arsenic (TAs) and arsenic species, among others, are established as the two aqueous phases mix.

Hydrous ferric oxides (HFO) are precipitated around focused venting, and coat the surrounding sediments visibly to 150 m away. HFO coatings, mechanical transport and weathering of volcanoclastic sediments, as well as dissolution of carbonate sediments nearer to venting, combine to alter sediment chemistry substantially.

Tutum Bay surface sediments have a mean As concentration of 527 mg/kg. …

Modeling The Impacts Of An Employer Based Travel Demand Management Program On Commute Travel Behavior, Liren Zhou

USF Tampa Graduate Theses and Dissertations

Travel demand Management (TDM) focuses on improving the efficiency of the transportation system through changing traveler's travel behavior rather than expanding the infrastructure. An employer based integrated TDM program generally includes strategies designed to change the commuter's travel behavior in terms of mode choice, time choice and travel frequency. Research on TDM has focused on the evaluation of the effectiveness of TDM program to report progress and find effective strategies. Another research area, identified as high-priority research need by TRB TDM innovation and research symposium 1994 [Transportation Research Circular, 1994], is to develop tools to predict the impact of TDM …

High School Outcomes Of Middle School Bullying And Victimization, Marissa A. Feldman

USF Tampa Graduate Theses and Dissertations

Previous research has revealed that bullying behaviors are negatively related to psychological, behavioral, social, and academic development. However, much of what is known has been determined from cross-sectional or year-long longitudinal studies conducted in elementary or middle school. The present study examined the longer-term correlates of bullying and victimization during the critical transition from middle to high school. Archival data from a large southern school district examined the longer-term implications of bullying and victimization of a middle school cohort (N=1,249). Results revealed that, during the initial survey year and over the following four-year period, self-identification as a bully was related …

Secondary Pre-Service Teachers’ Knowledge And Confidence In Dealing With Students’ First Amendment Rights In The Classroom, Ian Call

USF Tampa Graduate Theses and Dissertations

Every year teachers find themselves involved in conflicts dealing with violations of students' First Amendment rights to freedom of expression and freedom of religion. Students and parents file lawsuits against school districts because they feel teachers and administrators have violated their First Amendment rights. As a result, many teacher preparation programs require pre-service teachers to learn about educational law and the rights students have at school. Yet, little research exists about how well pre-service teachers are prepared to deal with First Amendment issues in the classroom.

The purpose of this study was to investigate how well pre-service teachers are prepared …

The Study Of Compensatory Motions While Using A Transradial Prosthesis, Stephanie Lutton Carey

USF Tampa Graduate Theses and Dissertations

Improvement of prostheses requires knowledge of how the body adapts. A transradial prosthesis without a dynamic wrist component may cause awkward compensatory motion leading to fatigue, injury or rejection of the prosthesis. This work analyzed the movements of shoulder, elbow and torso during four tasks: drinking from a cup, opening a door, lifting a box and turning a steering wheel.

The main purpose of this study was to determine if using a basic transradial prosthesis that lacks motion of the forearm and wrist would cause significant compensatory motion of the shoulder, elbow and torso during the tasks. The second purpose …
