Water Quality Monitoring In A Pilot Marine Integrated Aquaculture System, Alex W. Kruglick

USF Tampa Graduate Theses and Dissertations

Land based aquaculture systems are growing in popularity, and there is a drive to improve the efficiency of their energy and water systems for both economic and environmental benefit. Recirculating Aquaculture Systems (RAS) generally refer to systems that recycle their wastewater streams to be more or less a zero discharge facility. A more sustainable approach is emerging in the form of Integrated Aquaculture Systems (IAS) where maximum utility is realized from the various components so that fresh water use is reduced, water quality is improved, energy use is reduced, and new markets are created or fulfilled. Under a grant from …

Race, Ethnicity, And Exclusion In Group Identity, Rochelle Milne Burnaford

USF Tampa Graduate Theses and Dissertations

The current project investigates exclusion in terms of racial/ethnic identity and group behavioral norms. Research concerning the "black sheep effect" evidences the tendency for group members to derogate a fellow in-group member who has violated an important social norm (Marques, Yzerbyt, & Leyens, 1988). Similarly, Oyserman's (2007) model of identity-based motivation argues that any group identity can shape behavior through a process of identity infusion such that group members are motivated to behave in ways that are in-group identity-infused and equally avoid behaviors that are out-group identity-infused. Finally, identity misclassification research provides evidence that individuals feel threatened by the notion …

The Causes And Effects Of Get Tough: A Look At How Tough-On-Crime Policies Rose To The Agenda And An Examination Of Their Effects On Prison Populations And Crime, Cheyenne Morales Harty

USF Tampa Graduate Theses and Dissertations

The paper analyzes the rise of get-tough crime legislation to the American public policy agenda and examines the effects of these policies on crime and inmate populations. Get-tough policies analyzed include sentencing reform, the War on Drugs and collateral consequences. Because there is no empirical literature on the effect of collateral consequences on crime, the paper employed an OLS regression model partly derived from institutional anomie theory to test for criminogenic effects. The study then employed OLS regression analysis to determine the affect of these independent variables on crime rates in each of the 50 states. The study concluded that …

The Relationship Between Death Depression And Death Anxiety Among Cancer Patients In Saudi Arabia, Doaa A. Almostadi

USF Tampa Graduate Theses and Dissertations

Abstract

Cancer is one of the main public health problems in the world. People diagnosed with cancer may become depressed and fearful of dying. This causes them to question treatments and sometimes avoid treatment altogether. Cancer may change the person's life and the lives of others around them. The current study focused on the psychosocial impact of impending death for cancer patients in Saudi Arabia. Currently, the relationship between the death anxiety and death depression in persons with cancer in Saudi Arabia is not yet clear. Added to that, little research has been conducted with Muslim cancer patients and their …

Renegotiating Identities, Cultures And Histories: Oppositional Looking In Shelley Niro's "This Land Is Mime Land", Jennifer Danielle Mccall

USF Tampa Graduate Theses and Dissertations

My master's thesis explores the photographic series "This Land is Mime Land," which Shelley Niro made in 1992. Despite this work's complex form and structure, there are currently no sustained studies of this series alone, or books solely dedicated to Niro's art. Instead, "Mime Land" is often discussed in compilations that address a number of Native artists, Western feminist practices, or multiple works in Niro's oeuvre. My thesis fills this gap, as I closely investigate how "Mime Land" asks the viewer to look at visual culture, histories and Niro herself. Bell hooks's definition of the "oppositional gaze" - meaning a …

A Multifaceted Analysis Of Early Stage Non-Small Cell Lung Cancer Data, Madhusmita Behera

USF Tampa Graduate Theses and Dissertations

Some early stage NSCLC patients have a better survival prospects than others. In any event, the long-term prognosis for NSCLC patients is poor. Various measures were investigated to gain a better understanding of those patient characteristics that confer better survival or predict disease recurrence. A dataset comprised of stage 1 NSCLC patients (n=162) that underwent resection was investigated. Clinical variables (CVs) and tissue microarray (TMA) images with DNA repair protein and standard H&E expressions were investigated. Patients were dichotomized into two groups by survival characteristics and logistic regression (LR) modeling was used to predict favorable survival outcome. Various patient strata …

Tales Of Empire: Orientalism In Nineteenth-Century Children's Literature, Brittany Renee Griffin

USF Tampa Graduate Theses and Dissertations

Children's literature often does not hold the same weight in the studies of a culture as its big brother, the novel. However, as children's literature is written by adults, to convey information which is important for a child to learn in order to be a functioning member of that society, it can be analyzed in the same way novels are, to provide insight into the broad sweeping issues that concerned the adults of that era. Nineteenth-century British children's literature in particular reveals the deep-seated preoccupation the British Empire had with its eastern colonies, and shows how England's relationship to those …

Synthesis And Characterization Of Nanocomposites For Electrochemical Capacitors, Farah Alvi

USF Tampa Graduate Theses and Dissertations

Presently there are deep concerns over the environmental consequences and the consumption of non-renewable energy sources, with the accelerated greenhouse effect, triggered enormous interest in the use of renewable energy sources e.g., solar, hydropower, wind and geothermal. However the intermittent nature of harvesting renewable energy sources has recently gained considerable attention in the alternative reliable, cost effective, and environmentally friendly energy storage devices. The supercapacitor and lithium ion batteries are considered more efficient electrical energy storage devices than conventional energy storage systems.

Both devices have many useful and important applications; they could be an excellent source for high power and …

Matrix Metalloproteinase Genes Are Transcriptionally Regulated By E2f Transcription Factors: A Link Between Cell Cycle Control And Metastatic Progression, Jacqueline Lea Johnson

USF Tampa Graduate Theses and Dissertations

The RbµE2F transcriptional regulatory pathway plays a critical role in the cell cycle. Rb is inactivated through multiple waves of phosphorylation, mediated mainly by cyclin D and cyclin E associated kinases. Once Rb is inactivated, cells can enter Sµphase. Collectively, three Rb family members and ten E2F proteins coordinate every additional stage of the cell cycle, from quiescence to mitosis. However the RbµE2F pathway is frequently altered in cancer. Aside from cell proliferation, the RbµE2F pathway regulates other essential cellular processes including apoptosis, cell differentiation, angiogenesis and DNA damage repair pathways, but its role in invasion and cancer progression is …

A Ctd Biotag For Mid-Sized Marine Predators, Heather Broadbent

USF Tampa Graduate Theses and Dissertations

Biologging tools for investigating the study of fine-scale linkages between animal behavior and the physical microstructure of the marine habitat are technically limited by substantial size, high cost or low sensor resolution. However, recent advances in electronic technologies and process techniques present attractive alternatives to current tag designs. Motivated by the need for a low-cost, compact CTD biotag for medium-sized marine animals, the University of South Florida Center for Ocean Technology developed a multi-sensor biotag for quantitative measurements of ocean salinity. This dissertation describes the development and performance of a novel CTD biotag used for animal-borne measurements of the physical …

Impact Of Bullying Prevention Training On The Knowledge, Attitude, And Behavior Of Pre-Education Majors (Future Trainers), Seriashia J. Chatters

USF Tampa Graduate Theses and Dissertations

Bullying is a persistent problem that negatively affects the academic performance, and the psychological, social, and emotional well-being of targeted students. Research indicates most bullying is prejudice-based. Bullying and prejudice reduction interventions used in school systems encourage empathy towards the target student to reduce these behaviors, and current national and international interventions recommend focusing on bullies, targets (or victims), and bystanders. Interventions are conducted by individuals (trainers) trained to implement such programs, a model known as train-the-trainer. Teachers and pre-education majors usually volunteer to become trainers. Effectiveness of interventions may depend on the trainees' knowledge, empathy, and adherence to the …

The Role Of Tumor Suppressors, Ship And Rb, In Immune Suppressive Cells, Michelle Marie Collazo Ruiz

USF Tampa Graduate Theses and Dissertations

Regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSC) have been extensively studied in the past 30-40 years. Their potent suppressive capacity shown in several pathological and clinical settings, such as cancer and transplantation, has made it evident that better understanding their development and function is critical.

Specifically, Tregs play a pivotal role in preventing autoimmunity, graft-versus-host disease (GvHD), and organ graft rejection. We previously demonstrated that germline or induced SH2 domain-containing inositol 5-phosphatase (SHIP) deficiency in the host abrogates GvHD. Here we show that SHIP-deficiency promotes an increase of FoxP3+ cells in both the CD4+CD25+ and the CD4+CD25- T …

Vent-Fault Spatial Study Of Selected Volcanic Fields Of Southwestern North America And Mexico, Michelle Leonard

USF Tampa Graduate Theses and Dissertations

Of fundamental concern in volcanic hazard and risk assessment studies of volcanic systems is what role crustal structures might play in the ascent of magma through the crust. What are the processes that govern the spatial distribution and timing of eruptions, especially in populated areas or near sensitive facilities? Many studies have drawn the conclusion that faults play a critical role as easily–exploitable crustal weaknesses along which magma can ascend. Great care must be used when assuming a causative relationship between patterns of vents and faults especially when such relationships may be incorporated into hazard assessment models or other forecasting …

USF Tampa Graduate Theses and Dissertations

The purpose of this investigation was to compare the efficacy of three methods for detecting differential item functioning (DIF). The performance of the crossing simultaneous item bias test (CSIBTEST), the item response theory likelihood ratio test (IRT-LR), and logistic regression (LOGREG) was examined across a range of experimental conditions including different test lengths, sample sizes, DIF and differential test functioning (DTF) magnitudes, and mean differences in the underlying trait distributions of comparison groups, herein referred to as the reference and focal groups. In addition, each procedure was implemented using both an all-other anchor approach, in which the IRT-LR baseline model, …

The Effects Of Oxygen On The Electrophysiology Of Co2/H+-Chemosensitive And -Insensitive Neurons Of The Solitary Complex Of The Rat, Michael Patrick Matott

USF Tampa Graduate Theses and Dissertations

This study tested the hypothesis that decreasing the control O₂ level from 95% to 40% (5% CO₂ + 55% N₂) maintains viability in caudal solitary complex (cSC) neurons in transverse slices (~300-400ꝳ) prepared from neonatal rat (P2-22) maintained at 32-34°C. The underlying rationale is to reduce exposure to redox and nitrosative stimuli generated during several hours of exposure to 95% O₂ that produces a tissue O₂ tension throughout the slice which is in excess of 203 kPa (2.0 atmospheres absolute,ATA) oxygen. Whole cell recordings of cSC neurons maintained in 40% O₂ exhibited spontaneous …

Studying Socioeconomic Trends Through Cemetery Sales Records: A Case Study Of Greenwood Cemetery, Orlando, Florida, Victoria Abigail Kennedy Lawrence

USF Tampa Graduate Theses and Dissertations

Cemeteries are microcosms of society bound together in sacred spaces. As manifestations of social mores, cemeteries allow anthropologists to obtain information on social development and structure. Where noninvasive study is mandated, crucial methods of interpretation include studies of landscape design, floral incorporation, grave marker design and development, and grave mementos. This thesis discusses these and other methods as they are used to infer group mores. It also indicates how information acquired from methods can be adversely affected by outside influences, such as vandalism, weathering, and replotting. This thesis adds to known methods of cemetery research another unbiased, noninvasive tool that …

Deconstructing The "Power And Control Motive": Developing And Assessing The Measurability Of Internal Power, Shelly Marie Wagers

USF Tampa Graduate Theses and Dissertations

Despite the increased social recognition, law and policy changes within the criminal justice system, and the widespread use of court mandated batterer intervention programs (BIPs) domestic violence continues to be a persistent problem. The lack of significant decline in incidence rates along with a growing body of empirical evidence that indicates BIPs are, at best, only moderately effective raises serious concern. Effective policies and programs are based upon empirically tested theory. The assertion "the batterer's motive is power and control" has become fundamental to almost all of our currently used and accepted mainstream theoretical explanations regarding domestic violence. However, the …

The Effects Of Informational Prompts And Performance Feedback On Recyclign Behavior, Erin Marie Zandecki

USF Tampa Graduate Theses and Dissertations

Recycling behavior was examined by the implementation of Informational Prompts and Performance Feedback. Prompts containing facts on recycling and waste along with group performance feedback were studied at The Florida Mental Health Institute at The University of South Florida (Tampa campus). Informational Prompts were introduced by placing informational facts about recycling and waste by 26 bins throughout the building. Performance feedback signs were placed by the same bins and included the frequency of recycled material and trash discarded in the recycling bins on a daily basis when the campus was open. The results showed that both interventions increased recycling. Informational …

Optimization Of Bio-Impedance Sensor For Enhanced Detection And Characterization Of Adherent Cells, Dorielle T. Price

USF Tampa Graduate Theses and Dissertations

This research focuses on the detection and characterization of cells using

impedance-based techniques to understand the behavior and response of cells to internal/environmental changes. In combination with impedimetric sensing techniques, the biosensors in this work allow rapid, label-free, quantitative measurements and are very sensitive to changes in environment and cell morphology. The biosensor design and measurement setup is optimized to detect and differentiate cancer cells and healthy (normal) cells. The outcome of this work will provide a foundation for enhanced 3-dimensional tumor analysis and characterization; thus creating an avenue for earlier cancer detection and reduced healthcare costs.

An Evaluation Of Reactivity To Observer Presence While Self-Monitoring To Improve Swimming Performance, Sara Wendi Schonwetter

USF Tampa Graduate Theses and Dissertations

The current study evaluated the effects of self-monitoring by swimmers to improve their performance at practice and assessed the effects of reactivity to observer presence on their performance. Additionally, it investigated the accuracy of the swimmers' self-reports. Seven public high school swim team members used program boards to self-monitor in order to increase the number of assigned laps completed at practice. Reactivity to observer presence was assessed by having a confederate record the number of laps completed during observer absent conditions. A series of AB replications and an ABAB reversal design were used. The percentage of assigned laps completed increased …

Caregiver Training: Increasing Generalization Of Parenting Skills Through Teaching Caregivers To Recognize Child Behavior, Mary Rachel Sawyer

USF Tampa Graduate Theses and Dissertations

Previous research has demonstrated the efficacy of a behavioral parent training program for increasing the accuracy of trained skills; however, few studies have examined the extent to which those skills generalize to the natural environment (i.e., the home) and are used with the target individual (i.e., the child). In addition, little is known about the direct effect that caregiver implementation of the skills has on child behavior. A multiple baseline across participants design was used to (a) assess caregiver accuracy with implementation of three parenting skills, and (b) assess subsequent effects of the parenting skills on child behavior. Results demonstrated …

Evaluation Of Video Modeling And In Situ Training To Teach Gun Safety Skills To Individuals With Autism Spectrum Disorder, Kelsey Lynn Morgan

USF Tampa Graduate Theses and Dissertations

Currently, there is no known research on teaching gun safety skills to individuals with developmental disabilities. Research has shown that children typically engage in gunplay behaviors if they find a firearm. These behaviors can lead to unintentional firearm injuries and even death, especially for young children. Previous research has shown the success of video modeling for teaching various skills to individuals with autism. This study examined the effectiveness of video modeling for teaching gun safety skills to three children with autism spectrum disorder, and found that video modeling was effective for one participant, but in situ training was needed to …

Influence Of Stress And Cytokinic Profiles On Cognitive Performance In Older Adults, Kerri S. Rawson

USF Tampa Graduate Theses and Dissertations

ABSTRACT

With aging, changes in the immune system, makes cognitive performance, and the prevalence of stressors can lead to poorer overall functioning. Within the immune system, a balance should exist between cytokines regulating Th1 and Th2 immune responses; however, age-related declines in the endocrine and immune systems can disrupt this equilibrium. Several studies report higher levels of Th1 associated cytokines in inflammatory conditions of the brain, whereas fewer studies remark on Th2 associated cytokines and cognitive functioning. Declining cognitive abilities are a common concern that accompanies advancing age and some research has suggested the prevalence and impact of stressors lead …

Analysis And Optimization Of Broadband Measurement Cells For The Characterization Of Dielectric Polymer Films, Scott Skidmore

USF Tampa Graduate Theses and Dissertations

The current techniques and methodologies used in the field of material characterization are well documented and widely accepted as reliable and accurate. However, literature describing these techniques focuses on the algorithms used during material characterization; few studies have reposted on the design of, and the selection criteria for, the test fixtures themselves. This research focuses on the measurement cell with the goal of determining the sensitivity of the measurement cell to the addition of a thin film material.

Microstrip and coplanar waveguide were chosen for the analysis, which included three configurations of each transmission line geometry: a reference with no …

The Electronic Structure Of Biomolecular Self-Assembled Monolayers, Matthaeus Anton Wolak

USF Tampa Graduate Theses and Dissertations

The studies presented here address the characterization of the electronic structure of various self-assembled monolayers (SAMs) of peptide nucleic acid (PNA) and tetraphenylporphyrin (TPP) SAMs and arrays, formed on gold substrates.

PNA is a promising alternative to DNA for bio-sensing applications, as well as for strategies for self-assembly based on nucleic acid hybridization. In recent years charge transfer through PNA molecules was a focus of research due to possible applications in self-assembled molecular circuits and molecular tools.

Extraction Of Text Objects In Image And Video Documents, Jing Zhang

USF Tampa Graduate Theses and Dissertations

The popularity of digital image and video is increasing rapidly. To help users navigate libraries of image and video, Content Based Information Retrieval (CBIR) system that can automatically index image and video documents are needed. However, due to the semantic gap between low-level machine descriptors and high-level semantic descriptors, the existing CBIR systems are still far from perfect. Text embedded in multi-media data, as a well-defined model of concepts for humans' communication, contains much semantic information related to the content. This text information can provide a much truer form of content-based access to the image and video documents if it …

Altering A Secondary Tier Intervention To Examine The Effects Of Negative Reinforcement Contingencies On Elementary School Students, Stevie-Marie Swift

USF Tampa Graduate Theses and Dissertations

Problem behaviors in the school setting have become more frequent as well as challenging for teachers and faculty to decrease while attempting to help their students attain their academic goals. Within the last decade, school-wide positive behavior support (SWPBS) has become more widespread as an evidence-based practice within the school system. SWPBS uses a multi-tiered support structure in order to affect behavior change across an entire school population. Several common secondary interventions have been utilized with high success rates. However, the research conducted thus far using the Check-In/Check-Out (CICO) program, a secondary intervention, has shown a lesser degree of success …

A Deadly Way Of Doing Business: A Case Study Of Corporate Crime In The Coal Mining Industry, Charles Nickolas Stickeler

USF Tampa Graduate Theses and Dissertations

To this point, research on corporate crime has been, for the most part, overlooked by mainstream criminology. In particular, corporate violations of safety regulations in the coal mining industry have yet to be studied within the field of criminology. The purpose of this thesis is to examine the crimes of a coal mining corporation, a corporation whose business decisions led to the worst coal mining disaster in forty years, along with the deaths of twenty-nine men. This thesis will utilize a case study format in order to illustrate the crimes committed by this corporation. Previous literature covering the history of …
