Radical Religious Groups And Government Policy: A Critical Evaluation, Tori Chambers Lockler

USF Tampa Graduate Theses and Dissertations

Religion, many times, is one of the phenomena that is misunderstood and often rejected due to apprehension. There is an expected "norm" within our culture for religion and those that fall outside that "norm" are typically criticized for their beliefs. Within Christianity there are a number of extremist groups that follow millennial doctrines and believe they are living in the end times. These organizations tend to view the government as oppressive, disrespectful, immoral and corrupt. Because of this when an incident occurs with one of these millennial groups and the government steps in to control the situation, the way it …

Cord Blood Cell Therapy For Ischemic Stroke, Martina Vendrame

USF Tampa Graduate Theses and Dissertations

Infusion of the "mononuclear fraction" of human cord blood cells (HUCBC), which is composed of immature blood cells and hematopoietic progenitors, is known to reduce neurobehavioral deficits in rats subject to middle cerebral artery occlusion (MCAO). When MCAO rats are infused with 106 cells 24 hours after the induction of the stroke, their motor function improves. To extend these findings, we first examined the behavioral recovery of MCAO rats in the presence of increasing doses of HUCBC. The recovery in behavioral performance seen with measurements of spontaneous activity and motor deficits, depended on the amount of cells delivered, with 10 …

Behavioral And Morphological Consequences Of Rearing Florida Largemouth Bass With Non-Elusive Prey, Alpa Patel Wintzer

USF Tampa Graduate Theses and Dissertations

(1) Hatchery-reared Florida largemouth bass, Micropterus salmoides floridanus, feed on inert pellet food while their wild counterparts capture elusive prey. Differences in levels of prey elusivity often mandate the use of alternate methods of prey capture and are accompanied by a related phenotypic change.

(2) This study investigates (a) differences between the prey capture kinematics and strike modes of hatchery and wild juvenile Florida largemouth bass raised on pellets and live prey, and (b) whether elusivity-based variation in prey capture translates to a phenotypic and functional change during skull development.

(3) Analysis of high-speed videography demonstrates that wild bass capture …

Outsiders And The Impact Of Party Affiliation In Ecuadorian Presidential Elections, Rachel Lynne Hammond

USF Tampa Graduate Theses and Dissertations

How has the party affiliation of presidential candidates impacted presidential elections in Ecuador? Historically, how have political party candidates and outsiders performed in elections and how has this changed over the last 20 years of democratic history? This case study attempts to answer fundamental questions about the connections between parties and electablility of presidential candidates. In a country with an inchoate party system and a history of populism, personalist candidates have always had relatively high levels of electoral success. Yet, it would seem that preference for unaligned candidates is increasing. After years of domination by political party candidates, the Ecuadorian …

The French Art Song Style In Selected Songs By Charles Ives, Christy Jo Talbott

USF Tampa Graduate Theses and Dissertations

Charles Ives is commonly referred to as the "Father of American Music." The implication is one that Ives himself would agree with, that he wrote purely American ideas from his own environment without reference to other styles or methods, in particular the widespread European tradition. Some composers, like Aaron Copland and Roger Sessions, created an American sonority by incorporating the concepts of musical construction they studied at the Paris Conservatoire. Ives, conversely, received no instruction in Europe, but the techniques so prevalent in the music of the French art song are found in certain songs written by Ives. Though he …

Udp-Glucuronosyltransferase (Ugt) Genetic Variants And Their Potential Role In Carcinogenesis, Jean Bendaly

USF Tampa Graduate Theses and Dissertations

Exposure to polycyclic aromatic hydrocarbons (PAHs) such as benzo(a)pyrene are important risk factors for cancer. Three UDP-glucuronosyltransferases, UGT1A9, UGT1A10, and UGT2B7, have been shown to play an important role in the phase II metabolism of carcinogenic metabolites of BaP. Because UGT1A9 and UGT2B7 are well-expressed in digestive tract tissues including liver and colon, it is possible that genetic variations in either enzyme may play an important role in colon cancer risk. However, UGT1A10 is extrahepatic and is expressed in the oral cavity and the larynx; therefore, genetic variations in this enzyme may play an important role in risk for orolaryngeal …

Physiological Responses Of Men During The Continuous Use Of A Portable Liquid Cooling Vest, Theresa J. Medina

USF Tampa Graduate Theses and Dissertations

Heat stress is a well documented hazard across industries. The combination of environmental conditions, work demands, and clothing contribute to heat strain. Left unchecked, heat strain causes changes in an individual's physiological state that can lead to serious and fatal conditions with little warning. Although engineering and administrative controls are the first choice to abate this hazard, they frequently are not feasible. In these cases, personal cooling is often employed. There are three main types of personal cooling: liquid, air, and passive. Each has its own advantages and disadvantages.

This study focuses on continuous cooling using a portable liquid cooling …

Governing Wayward Consumers: Self-Change And Recovery In Debtors Anonymous, Adam Morenberg

USF Tampa Graduate Theses and Dissertations

Previous research on self-change in support groups has focused on the ways individuals accomplish self-change in the "local cultures" of the support group settings. This ethnographic study of the 12-step self-help group Debtors Anonymous (DA) departs from that tradition by focusing on the ways that DA members achieve self-change by employing "recovery" strategies learned from the group in their everyday lives. DA members enter the group during financial crises, and often believe they cannot manage their own personal finances. By learning techniques of financial management taught by the group, DA members gradually gain "sobriety" and financial management skills. This analysis …

Women, Domestic Abuse, And Dreams: Analyzing Dreams To Uncover Hidden Traumas And Unacknowledged Strengths, Mindy Stokes

USF Tampa Graduate Theses and Dissertations

Domestic abuse is the number one cause of injury to women in the United States. Women and their children flee everyday to shelters to escape the abuse. Once inside the shelters, material resources are rendered so that the women can continue to lead lives outside the shelter and different therapies are employed so that the women can better understand the abuse and their options once leaving. A type of therapy used in other therapeutic forums, such as patients sexually abused as children, is dream analysis. This type of therapy has allowed formerly traumatized victims a safe space to uncover hidden …

An Empirical Analysis Of The Role Of Mitigation In Capital Sentencing In North Carolina Before And After Mckoy V. North Carolina (1990), Janine Kremling

USF Tampa Graduate Theses and Dissertations

This study focuses on the influence of mitigating circumstances on the sentencing outcome before and after the McKoy (1990) decision. In McKoy (1990) the Supreme Court decided that the jurors did not have to find mitigating circumstances unanimously. Results are reported based on a sample of North Carolina first-degree murder cases where the state sought the death penalty. Logistic regression is used to determine the importance of mitigating circumstances as predictors of jury decision-making in North Carolina, controlling for the variety of other factors that influence that decision.

The descriptive statistics show that the average number of mitigating circumstances submitted …

“Symbolism Of Language: A Study In The Dialogue Of Power Between The Imperial Cult And The Synoptic Gospels”, Sharon Matlock-Marsh

USF Tampa Graduate Theses and Dissertations

Long before the writings of the New Testament gospels, where Jesus was being proclaimed as the Son of God, and Savior, the world existing under the influences of Hellenism resulting from the conquests by Alexander the Great in 323 BCE, had already been well acquaint

ed with and expected to hear certain symbolic language in determining titles for their divine ruler the emperor. Living within a cosmological framework, i.e., a sacred cosmos, the citizens of the empire accepted the emperor as the manifestation of divinity in the world. This belief existed for centuries prior to Christianity as a reality that …

Feasibility Of Using Nanofiltration As A Polishing Process For Removal Of Cyanobacterial Exudates From Treated Surface Water, Anand J. Mody

USF Tampa Graduate Theses and Dissertations

Nanofiltration (NF) membrane technology is effective for removal of natural organic matter (NOM) and Disinfection By-Product (DBP) precursors from treated surface water (Allgeier et al., 1995, Chellam et al., 2000, Smith et al., 2002). However, there is a need to control other micropollutants, such as compounds released from algal blooms. In this research, the feasibility of using NF for removal of cyanobacterial exudates was evaluated as a polishing process for conventionally treated surface water.

Screening tests were conducted to compare the performance of four NF membranes, Filmtec's NF90 and NF270, and Hydranautics's LFC1 and NTR7450, for removal of NOM and …

Chemical And Biological Investigation Of The Antarctic Red Alga Delisea Pulchra, Santhisree Nandiraju

USF Tampa Graduate Theses and Dissertations

Our interest in the red alga Delisea pulchra (=D.fimbriata) (Greville) Montagne 1844 (Rhodophyceae, Bonnemaisoniales, Bonnemaisoniaceace) was stimulated by its activity in the biosssays done at Wyeth Pharmaceuticals. Halogenated compounds from D. pulchra interfere with Gram-negative bacterial signaling systems, affect the growth of Gram-positive bacteria, inhibit quorum sensing and swarming motility of marine bacteria (inhibit bacterial communication). They also inhibit surface colonization in marine bacteria and exhibit antifouling properties against barnacle larvae and macroalgal gametes.

Chemical investigation of D.pulchra collected near Palmer Station, Antarctica yielded three new dimeric halogenated furanones, pulchralide A-C (41-43), along with previously reported …

Australian Great Barrier Reef Initiation Timing Constrained By Seaward Shallow-Water Sediment Drift Architecture (Odp Leg 194, Marion Plateau), Stephen P. Obrochta

USF Tampa Graduate Theses and Dissertations

I resolved the sedimentary architecture of a shallow water (< 500 m), hemipelagic sediment drift located on the Marion Plateau, seaward and downstream of the Great Barrier Reef (GBR). The drift responded increasingly to sea-level fluctuations during the Pleistocene. In the early Pleistocene, local climatic variations introduce a precessional rhythm to drift architecture that is out of phase with sea level-forced cyclicity. Beginning in the mid Pleistocene, sea level variations dominate drift architecture, with the highest carbonate and terrigenous fluxes likely occurring during highstand and transgression, respectively. At the sea-level transgression of MIS 15 and subsequent isotope stages, the phasing of maximum terrigenous flux corresponds to sea-level transgression, indicating siliciclastic sediment accumulated on the continental shelf behind an exposed barrier reef during the lowstand of MIS 16 and was remobilized by rising sea-level. These sedimentological data indicate GBR initiation occurred during MIS 17. The normal polarity exhibited by the central GBR and thick section of underlying sediments rules out initiation during MIS 19.

MIS 17 was the first of the asymmetric glacial cycles characteristic of the Late Pleistocene. If the Florida Keys and Belize barrier reef initiations were indeed simultaneous with that of the GBR, then the changing nature of cyclicity in global sea level and climatic fluctuations likely influenced the initiation of the world's major, modern barrier reefs.

Optimization Of The Two Stage Process For Cu(In,Ga)Se2 Solar Cells, Shirish Pethe

USF Tampa Graduate Theses and Dissertations

Copper Indium Gallium DiSelenide absorber layers are fabricated using a two stage manufacturing friendly process. The first step involves the sequential deposition of Copper and Gallium and co-deposition of indium and selenium at 275oC. This is followed by the second stage where the substrate is annealed in the presence of Selenium and a thin layer of copper is deposited to neutralize the excess Indium and Gallium on the surface to form the CIGS absorber layer. The top copper thickness as well as the time of deposition was varied to study the effect of Copper on the performance of the cells. …

Fuzzy C-Means Clustering Approach To Design A Warehouse Layout, Vaibhav C. Naik

USF Tampa Graduate Theses and Dissertations

Allocation of products in a warehouse is done by various storage policies. These are broadly classified into three main categories: dedicated storage, randomized storage, and class-based storage. In dedicated storage policy a product is assigned a designated slot while in random storage policy incoming product is randomly assigned a storage location close to the input/output point. Finally, the class-based storage is a mixed policy where products are randomly assigned within their fixed class. Dedicated storage policy is most commonly used in practice. While designing large warehouse layout, the product information in terms of throughput and storage level is either uncertain …

Analysis Of Fluid Circulation In A Spherical Cryogenic Storage Tank And Conjugate Heat Transfer In A Circular Microtube, P Sharath Chandra Rao

USF Tampa Graduate Theses and Dissertations

The study considered development of a finite-element numerical simulation model for the analysis of fluid flow and conjugate heat transfer in a zero boil-off (ZBO) cryogenic storage system. A spherical tank was considered for the investigation. The tank wall is made of aluminum and a multi-layered blanket of cryogenic insulation (MLI) has been attached on the top of the aluminum. The tank is connected to a cryocooler to dissipate the heat leak through the insulation and tank wall into the fluid within the tank. The cryocooler has not been modeled; only the flow in and out of the tank to …

Behavioral Analysis Of Interactions Between Teachers And Children With Selective Mutism, Jason D. Wallace

USF Tampa Graduate Theses and Dissertations

The present study focused on the interactions between a child with selective mutism and that child's teachers. The hypothesis was that the teachers unknowingly maintained the mutism by not placing the expectations of speech on the child. Therefore, by training three out of the four teachers how to interact with the child with selective mutism, and using the fourth teacher as a control, the researchers were able to identify that the training not only changed the three teachers' behaviors, but also the child with selective mutism's behaviors as well. Also, based on a pre-training/post-training test, the teachers had a much …

The Utilization Of Enzymes In The Synthesis And Modification Of Natural And Nonnatural Compounds: A Chemo-Enzymatic Approach To Enantiomerically Pure Compounds, Jason A. Carr

USF Tampa Graduate Theses and Dissertations

The employment of enzymes and whole cells has been important in many industries for centuries. However, it is only in the last 30 years that the use of enzymes for the synthesis of high-value fine chemicals has enjoyed increasing popularity. In fact, esterases and lipases are used almost routinely these days to provide optically active building blocks for the construction of imaginative new routes to chiral target molecules. The major topic of this work describes the utilization of enzymes (namely lipases) in the synthesis and modification of natural and non-natural compounds.

Chapter 1 outlines the strengths and weaknesses of the …

Performance Analysis Of Tcp/Ip Over High Bandwidth Delay Product Networks, Subodh Kerkar

USF Tampa Graduate Theses and Dissertations

In today's Internet scenario, the current TCP has performed reasonably well. As the Internet has scaled up in load, speed, size and connectivity by the order of six over the past fifteen years, the TCP has consistently avoided severe congestion throughout this same period. Applications involving high performance computings such as bulk-data transfer, multimedia Web streaming, and computational grids demand high bandwidth. These applications usually operate over wide-area networks and, hence, performance over wide-area networks has become a critical issue. Future applications will need steady transfer rates in the order of gigabits per second to support collaborative work. TCP, which …

Modeling Demand Uncertainty And Processing Time Variability For Multi-Product Chemical Batch Process, Rishi Darira

USF Tampa Graduate Theses and Dissertations

Most of the literature on scheduling of multi-product batch process does not consider the uncertainties in demand and variability in processing times. We develop a simulation based variable production schedule model for a multi-product batch facility assuming zero wait transfer policy and single product campaign. The model incorporates the demand uncertainties and processing time variability. The impact of demand uncertainties is evaluated in terms of total annual cost, which comprises of the backorder and inventory costs per year. The effect of variability in processing time is measured by the annual production time. We also develop a constant production schedule model …
