Longshore Sediment Transport From Northern Maine To Tampa Bay, Florida: A Comparison Of Longshore Field Studies To Relative Potential Sediment Transport Rates Derived From Wave Information Study Hindcast Data, Joseph F. Van Gaalen

USF Tampa Graduate Theses and Dissertations

This paper examines the regional longshore sediment transport pattern of the seaward coast of the United States and Gulf of Mexico from northern Maine to Tampa Bay, Florida. From previous studies it is known that along the coast there are variations in direction of sediment transport known as nodal zones as well as variations in sediment transport rate. Wave Information Study (WIS) hindcast data for the interval 1976 through 1995 (United States Army Corps of Engineers, 2003) provide a spatially continuous model of the regional longshore current directions in the study area.

In chapter one, all available published field studies …

The study examined the background and steps that evolved throughout the reform process.

Specific constructs most frequently appearing in the literature relating to developing an organization were studied: (a) philosophical foundations, (b) change, (c) perception, (d) leadership, (e) teachers as leaders and (f) affect. Research on teachers' perspectives examined key elements …

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

USF Tampa 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 …

Race, Religion, And Attitudes Toward Capital Punishment: A Test Of Attribution Theory, Sheila M. Schlaupitz

USF Tampa Graduate Theses and Dissertations

The present study attempts to provide a more thorough understanding of public attitudes toward capital punishment. Two theories are tested toward this end, utilizing a random sample taken from the jury pool in Hillsborough County, Florida.

First, An indirect test of reference group theory demonstrates the degree to which faith group, religiosity, and race affect public attitudes toward the death penalty. Surprisingly, there is little, albeit mixed, support for reference group theory as it attempts to explain attitudes toward capital punishment. Using the relationships between religion and capital punishment attitudes that we presumed would emerge from the test of reference …

Managerial Decision Making And Stockholder Wealth Maximization: A Limited Dependent Variables Model Of The Choice Between Dividends And Stock Repurchases, Noel Reynolds

USF Tampa Graduate Theses and Dissertations

This research attempts to provide an explanation for the firm's choice of using either a dividend or a stock repurchase for distributing cash to its stockholders. It also provides an examination of the impact of the firm's disbursement decision on the stock market's resulting reassessment of the value of the firm.

Before analyzing the disbursement decision, I examine the stock market effects of dividends and stock repurchases using an event study methodology that corrects for the possible variance change effects of cash distribution announcements. I find that the measured wealth effects are statistically significant and similar, for the most part, …

A Comparative Simulation Of Type I Error And Power Of Four Tests Of Homogeneity Of Effects For Random- And Fixed-Effects Models Of Meta-Analysis, Lisa Therese Aaron

USF Tampa Graduate Theses and Dissertations

In a Monte Carlo analysis of meta-analytic data, Type I and Type II error rates were compared for four homogeneity tests. The study controlled for violations of normality and homogeneity of variance. This study was modeled after Harwell (1997) and Kromrey and Hogarty's (1998) experimental design. Specifically, it entailed a 2x3x3x3x3x3x2 factorial design. The study also controlled for between-studies variance, as suggested by Hedges and Vevea's (1998) study.

As with similar studies, this randomized factorial design was comprised of 5000 iterations for each of the following 7 independent variables: (1) number of studies within the meta-analysis (10 and 30); (2) …

USF Tampa Graduate Theses and Dissertations

From the perspectives of economic anthropology, feminist anthropology, and feminist theory, this applied anthropological study is an evaluation of a popular international development model targeting poor women. Based on the celebrated Grameen Bank of Bangladesh, the so-called "microcredit" model is designed as a poverty alleviation strategy to provide small loans to poor women in rural settings and is designed to facilitate microenterprise development. Due to the popularity of the microcredit model with the international development community, it is being replicated in different settings. Through an analysis of microenterprise development among Afro-Caribbean women, this study presents the argument that successful application …

Characterization Of Obsidian Sources In Pantelleria, Italy, Barbara A. Vargo

USF Tampa Graduate Theses and Dissertations

The study of prehistoric trade and exchange networks in the Western Mediterranean is directly linked to the identification and location of commodities available to Neolithic communities in that region. One of these commodities is a volcanic glass commonly known as obsidian.

This investigation focused on the procurement, processing, and distribution of obsidian from the island of Pantelleria, situated between the southwestern coast of Sicily in the Straits of Sicily and the northeastern coast of Africa near Cape Bon, Tunisia. Previous studies indicate that there are several chemically different source areas on the island.

Research involved the identification of primary obsidian …

In Search Of David Paul Davis, Rodney Kite-Powell

USF Tampa Graduate Theses and Dissertations

The 1920s land boom in Florida produced a wide variety of characters. Among the most important, but lesser known, of those was David Paul Davis. Davis was born in November 1885 in Green Cove Springs, Florida. His family moved to Tampa in 1895, where he attended school and held a number of different jobs. He left Tampa in 1908 and reappeared in Jacksonville in 1915. That same year, in Jacksonville, he married Marjorie H. Merritt.

The young couple moved to Miami in 1920, where Davis began to sell real estate. He became quite adept, developing a number of subdivisions in …

Studies On Antibacterial Activities Of N-Thiolated Β-Lactams And Their Polymeric Nanoparticles Against Mrsa, Jeung-Yeop Shim

USF Tampa Graduate Theses and Dissertations

Methicillin-resistant Staphylococcus Aureus (MRSA) is now the most challenging bacterial pathogen affecting patients in hospitals and in care centers, and has brought on the need to develop new drugs for MRSA. This thesis centers on studies of N-thiolated β-lactams, a new family of potent antibacterial compounds that selectively inhibit the growth of methicillin-resistant Staphylococcus aureus (MRSA).

Chapter 1 describes MRSA in more detail. Chapter 2 outlines experiments on the effect of a fatty ester group (CO₂R) on the C₄-phenyl ring of N-methylthio β-lactams, expecting that attachment of long chain ester moieties might increase the hydrophobicity, …

"Insolent And Contemptuous Carriages": Re-Conceptualizing Illegitimacy In Colonial British America, John Watkins

USF Tampa Graduate Theses and Dissertations

This Master's thesis investigates one particular aspect of sexuality in colonial Anglo America--the products of non-marital intercourse. Earlier historical research emphasized the importance of economic considerations in the creation of bastardy laws and the prosecution and punishment for violators of these statutes. Undoubtedly, financial anxieties were a major concern in out-of-wedlock births, but they were only one concern of many. Class, race, and gender dynamics were prominent in colonists' conceptualization of illegitimacy and largely defined who was at risk for having an "insolent and contemptuous carriage" and the resulting punishment for the debauched act. Elite, white officials made women, servants, …

Analytical Strategies In Deciding Bus Route Alignments, Sandeep Seshan Iyer

USF Tampa Graduate Theses and Dissertations

In this research a heuristic algorithm is developed for searching and identifying preferred actions as applied to the bus route design problem. The search routine evaluates each subsequent segment added to the route in the context of the value of that segment and also the value of future decisions and opportunities for subsequent segments. The total overall maximum accessibility of the system is calculated using a minimum path network between each node pair and adding the accessibility of all route segments. This is equivalent to assuming that there was a direct shortest path route between every two destinations in the …

The Omar Torrijos Regime: Implications For The Democratization Process In Panama, Emma Scribner

USF Tampa Graduate Theses and Dissertations

Since gaining independence from Colombia in 1903, Panama has witnessed both elitist democratic governments and authoritarian populist governments. The oligarchic system in place throughout much of Panama's history was a significant hindrance to real democracy taking hold within the country. Democracy was further set back by the inordinate power exerted by the US presence on the isthmus throughout the twentieth century. Omar Torrijos's time as head of the Panamanian government from 1969 to 1981 exhibited populist, paternalistic and personalistic characteristics. His government marked an attempt to establish a form of government based on popular democracy. While a number of social …

Towards A Single-Mode Dispensed Polymer Optical Waveguide, Jill Michelle Kalajian

USF Tampa Graduate Theses and Dissertations

Dispensed organic polymer optical waveguides suitable for single-mode operation were recently fabricated. Different dispensing pressures, polymers, and dispensing tips were used in the drawing method.

The waveguides were measured to be approximately 16[mu] wide and 0.8[mu] tall. This is significantly smaller than previously reported dimensions of 300[mu] x 3.5[mu] waveguides fabricated with a similar dispensed polymer method. The waveguides were also found to be suitable for single-mode operation through a series of approximate calculations . This is also something previously not achieved with the larger waveguides.

This novel approach to waveguide fabrication could reduce the expense and time of creating …

N-Thiolated Β-Lactams: Chemistry And Biology Of A Novel Class Of Antimicrobial Agents For Mrsa, Timothy E. Long

USF Tampa Graduate Theses and Dissertations

N-Methylthio beta-lactams represent a promising new family of antibacterial agents whose in vitro activity is confined largely to Staphylococcus species, including multidrug-resistant forms of S. aureus. Originally developed in the 1980's for use as synthetic intermediates, N-methylthio beta-lactams have recently been shown in these laboratories to possess intriguing biological properties which are addressed in Chapters I-IV. In terms of the antibacterial activities, the structural features and species specificities exhibited by these compounds are unlike those of any existing family of beta-lactam drugs. The lactams seem to exert their effects intracellularly, requiring passage of the bioactive species through the …

Psychological Factors Associated With Skin Cancer Detection Behaviors In Individuals With A Family History Of Melanoma, Lora M. Azzarello

USF Tampa Graduate Theses and Dissertations

Current ACS guidelines recommend routine screening for cancer (ACS, 2002). Motivation to adhere to guidelines may be different for individuals with and without a family history of melanoma (Jonna, et al., 1998). Prior research examining the relationship between family history and skin cancer detection behaviors (Berwick et al., 1996; Friedman et al., 1993; Oliveria et al., 1999) have failed to utilize a theoretical framework to derive hypotheses. The purpose of the present study was to examine the utility of Protection Motivation Theory (PMT) in explaining intentions to engage in skin cancer screening (SCS) and skin self-examination (SSE). In addition, the …

A Model For The Benefits Of Electronic Toll Collection System, Rajesh H. Chaudhary

USF Tampa Graduate Theses and Dissertations

Due to the degree of complexity related to measuring the advantage of establishing Electronic Toll Collection (ETC) systems, literature generally stops short of modeling an all-inclusive set of benefits of the system. In this research, a model that incorporates the impact on both the users and the society as a whole and evaluates the financial benefits over the lifespan of the ETC investment is developed.

Most of the values for the parameters used for calculating the benefits are taken from Federal Highway Administration (FHWA) and from similar studies conducted by transportation agencies, which is the setting that has motivated the …

Self-Interference Handling In Ofdm Based Wireless Communication Systems, Tevfik Yücek

USF Tampa Graduate Theses and Dissertations

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation scheme that provides efficient bandwidth utilization and robustness against time dispersive channels. This thesis deals with self-interference, or the corruption of desired signal by itself, in OFDM systems. Inter-symbol Interference (ISI) and Inter-carrier Interference (ICI) are two types of self-interference in OFDM systems. Cyclic prefix is one method to prevent the ISI which is the interference of the echoes of a transmitted signal with the original transmitted signal. The length of cyclic prefix required to remove ISI depends on the channel conditions, and usually it is chosen according to the worst …

Using The Ablls With English Language Learners: Implications For Students And Teachers, Lorie G. Schultz

USF Tampa Graduate Theses and Dissertations

English language learners are traditionally behind in academics such as reading, math and science. Hispanics, who make up the vast majority of English language learners, tend to not enroll in pre-school or higher education, have higher dropout rates and as adults earn less than whites. Common instructional strategies used in public schools are not meeting the needs of these students. The field of TESOL (Teachers of English to Speakers of Other Languages) has typically offered a wide variety of poorly defined teaching strategies that are not based on empirical research. Within public schools, assessment tends to serve the purpose of …

The Fleeting Effects Of Retrieval Cue Attributes In The Pier2 Memory Model, Amie L. Wilbanks

USF Tampa Graduate Theses and Dissertations

Processing Implicit and Explicit Representations (PIER2) is a model of memory that makes predictions about memory performance based on the interaction of known and newly acquired information by studying how implicitly activated associates affect episodic memory. Nelson and Zhang (2000) found a significant effect of cue connectivity in a multiple regression analysis of the variables known to affect cued recall, but at that time no manipulational experiments had studied the cue connectivity effect in the laboratory. The present paper presents a series of three experiments designed to investigate the effect of cue connectivity in the context of the PIER2 memory …

Toward An Integrated Communication Theory For Celebrity Endorsement In Fund Raising, Tracie M. Domino

USF Tampa Graduate Theses and Dissertations

Throughout the history of the United States, Americans customarily have given away their money, as well as their time to serve the common good. Americans will give "to build something, to fight something, or to save something" (Fink, 1990, p. 136). They make gifts to causes, or the societal problems represented by organizational missions, that are important to them. Individuals give not only to advance a common good, but also to receive private goods, or benefits that are internal, intangible, and in some cases, tangible (Steinberg, 1989).

To create this feeling of reciprocity for prospective donors who have not actually …

School Factors Related To The Social And Behavioral Success Of Children And Adolescents With Tuberous Sclerosis: Special Education Placement, Services, And Parental Involvement, Kathleen Walker Carlisle

USF Tampa Graduate Theses and Dissertations

The researcher examined the relationships between tuberous sclerosis, a multi-system genetic disorder, and school functioning through the use of a parent questionnaire and behavior rating scale. Information was gathered on the typical school experiences of children with tuberous sclerosis, including educational placement and services, behavioral functioning, parent involvement, and parent satisfaction. The results indicated that the majority of students with tuberous sclerosis are in special education and receiving related services. Three-quarters received one or more related services through the public school, and 30% received private related services paid for by their parents. Parent involvement was positively correlated with parent satisfaction, …

USF Tampa Graduate Theses and Dissertations

U.S. fisheries legislation requires National Marine Fisheries Service (NMFS) to attend to the critical social and economic issues surrounding the definition and identification of fishing communities, and to the effects that changes to the physical environment and regulatory decisions can have on such communities. To fulfil their mandate, National Marine Fisheries Service (NMFS) sponsored the research entitled "Identifying Fishing Communities in the Gulf of Mexico" to study the economic, social and cultural status of potential fishing communities along the Gulf of Mexico.

NMFS contracted the research project to Impact Assessment, Inc. to study 80 plus potential fishing communities in the …

Homosocial, Homoerotic, Bisexual, And Androgynous Bonds In Shakespeare’S Comedies, Klarisa Sokolovic-Cizmek

USF Tampa Graduate Theses and Dissertations

In the thesis I inquire into the nature of the same-sex bonds in Shakespeare’s comedies. I discuss seven pairs of characters and demonstrate how in his comedies, Shakespeare first created homosocial relationships, later homoerotic relationships, then bisexual relationships, and, finally, a couple that may be described as androgynous. I demonstrate that in the early comedies the relationships are primarily homosocial and serve the purpose of self-realization. The self-realization includes reaching of a balance between a “feminine,” and a “masculine” self, with the goal of becoming a mature, androgynous human being. Although there are some homoerotic undercurrents in both the male …
