Effects Of Stability Balls On Children With Autism Spectrum Disorder, Patricia A. Krombach

USF Tampa Graduate Theses and Dissertations

Children with ASD often display behavior problems that can lead to daily academic and social disruptions. Many teachers and therapists have sought to create classroom interventions that improve the length of time a child stays seated and focused on the required task. This has led to the introduction of stability balls as an alternative seating method for children, both on the autism spectrum and with other needs. This study used a multiple baseline design and duration data to evaluate the effects of stability ball seating on attending and in-seat behavior for children with ASD who received ABA therapy in their …

Effects Of Delay To Reinforcement On Selections For High-Tech And Low-Tech Leisure Items, Yuram Kim

USF Tampa Graduate Theses and Dissertations

Many children are exposed to excessively technology. Such use of technology may lead to health issues including obesity, attention deficits, and sleep disorders. Research has shown that parameters of reinforcement, such as quality and delay, may influence how children allocate their preferences. One way to drive preference away from high-tech toys may be to arrange delays to reinforcement following such selections and immediate reinforcement for an alternative response. In Experiment 1, four subjects who preferred high-tech leisure items over low-tech leisure items were identified through the pair-stimulus preference assessments. The results of Experiment 2 indicated that all subjects were sensitive …

The Effect Of Exercise Order On Body Fat Loss During Concurrent Training, Tonya Lee Davis-Miller

USF Tampa Graduate Theses and Dissertations

While the benefits of both cardiovascular exercise and resistance training have been well documented, there is a lack of evidence for the order of exercise that is most effective when both are done in the same day. This study was designed to look at two groups of participants performing both resistance (R) and cardiovascular (C) training in the same day to determine if their order, resistance before cardiovascular (R-C) or cardiovascular before resistance (C-R), matter with regard to changes in body composition, maximal strength, and maximal aerobic capacity. The participants were 17 women between the ages of 30 and 55 …

Assessment Of The Role Of Poly (Adp-Ribose) Polymerase In Drug-Induced Cardiomyopathy, Alexis I. Brinkerhoff

USF Tampa Graduate Theses and Dissertations

Drug-induced cardiotoxicity has resulted in a thorough evaluation of patient doses, treatments, and rehabilitation. One of the most commonly prescribed chemotherapeutic agents is cyclophosphamide. The active metabolite, acrolein, is one of the most potent inducers of cardiomyopathy. In this study, research was conducted on the H9c2 (2-1) cardiomyocyte cell line derived from the embryonic myocardium of rattus norvegicus to assess its competency for evaluation of the change in poly (ADP-ribose) polymerase (PARP) activity. The application of this model to study the effects of acrolein on PARP activation was chosen as an ideal determinant of cell damage produced by nitrogen mustards. …

Reinforcement Of Variability And Implications For Creativity, Harvey Ray Bayliss

USF Tampa Graduate Theses and Dissertations

One of the defining characteristics of Autism Spectrum Disorder (ASD) is repetitive, rigid, or stereotyped patterns of behavior. A proposed approach to treating such patterns is to provide reinforcement for response variability. Though research demonstrates that the variability of responses can be influenced by contingencies of reinforcement, no studies have examined the effects of placing contingencies on different units of behavior. The purpose of this study was to examine effects of two modified percentile schedules on variety of completed drawings and individual lines drawn by students with ASD who had been referred for engaging in rigid patterns of behavior. For …

Utilizing Immediate Feedback In Piano Pedagogy, Michael Szabo

USF Tampa Graduate Theses and Dissertations

Piano pedagogy is the study of the teaching of piano performance. Several effective methods have been developed since the early 1700's, but lack empirically supported techniques. Immediate feedback procedures have been shown to be effective with skill acquisition in various capacities within the literature. While some innovative techniques are being developed which utilize technologies such as video and sensor-based feedback, the true impact of these interventions has not been empirically validated. There is also a paucity of research in the behavioral literature evaluating the efficacy of immediate feedback procedures in acquisition of music performance. The current study evaluated the effectiveness …

An Alternative Ancien Régime? Elisabeth Vigée-Lebrun In Russia, Erin Elizabeth Wilson

USF Tampa Graduate Theses and Dissertations

In the last few decades interest in the life and work of Elisabeth Vigée-Lebrun has increased significantly, with numerous publications and a retrospective exhibition dedicated to her oeuvre. Yet, while much new and valuable information has been introduced, very little of it deals specifically with the period from 1795-1800 when she lived as an émigré in Saint Petersburg, Russia.

In this thesis I analyze two Russian portraits by Elisabeth Vigée-Lebrun, in relation to two earlier works she painted in Paris, the duchesse d’Orleans (1789) and Marie Antoinette, Queen of France (1783), elucidating the overt similarities to her earlier portraiture …

Cement Heat Of Hydration And Thermal Control, Ahmadreza Sedaghat

USF Tampa Graduate Theses and Dissertations

Heat of hydration is a property of Portland cement and a direct result of the chemical reaction between cement and water. The amount of heat released is dependent upon the cement mineralogical composition, curing temperature, water to cement ratio, and cement fineness. High temperature resulting from heat of hydration (thereon referred to as HOH) of cement can affect the hydration process, and consequently the kinetics of development of the mechanical properties of concrete. One of the main reasons triggering the interest in HOH of cement is its implication in thermal cracking of concrete. The high temperature gradient between the inner …

Multiple Case Study Of Factors Associated With Enrollment Of Women With Persistent Or Recurrent Ovarian Cancer In Clinical Trials In Central Florida, Judith Ann Ebbert

USF Tampa Graduate Theses and Dissertations

Study Purpose: Ovarian cancer, the most lethal gynecologic cancer, has had a relatively stable mortality rate since 1975, despite a decrease in mortality for all gynecologic cancers combined. Standard-of-care advances are needed to reduce ovarian cancer morbidity and mortality. Advances must, however, undergo a long, rigorously controlled research process that can take more than ten years before becoming available to the public. Further, few women with persistent or recurrent ovarian cancer are offered or enrolled in the clinical trials that do exist at select sites throughout the nation. The purpose of this multiple-case study is to identify necessary and/or sufficient …

Investigating Alternative Subsistence Strategies Among The Homeless Near Tampa, Florida, Matthew Peter Rooney

USF Tampa Graduate Theses and Dissertations

Modern homelessness is one of the most pressing social and political problems of our time. Several hundred thousand people experience homelessness in the United States each year, and the U.S. Department of Housing, which attempts to count those people, has admitted that their statistics are conservative estimates at best. A recent archaeological study (Zimmerman et al 2010) examining material culture associated with homeless communities in Indianapolis has suggested that those who are considered chronically homeless have generally abandoned wage labor and are instead pursuing urban foraging as a subsistence strategy. In order to better understand the structures of homeless communities, …

Solid Metaphor And Sacred Space: Interpreting The Paradigmatic And Syntagmatic Relations Found At Beth Alpha Synagogue, Evan Carter

USF Tampa Graduate Theses and Dissertations

With the destruction of the Second Temple in 70 CE, more than an iconic symbol of Jewish identity was destroyed. As the epicenter of religious life for Jews within the land of Israel, the Temple stood as both a symbol for religious hope and as the physical embodiment of Judaism. Yet, in the centuries that would follow synagogue’s like the one found at Beth Alpha would come to fill its absence.

In this thesis I will demonstrate how the use of Christopher Tilley’s theory of the solid metaphor helps us to better understand both the art and architecture of the …

Full Scale Evaluation Of Organic Soil Mixing, Kelly Costello

USF Tampa Graduate Theses and Dissertations

Soil mixing is a procedure that has proven to be effective for loose or soft compressible soils. The method stabilizes the soil in-place using specialized augers, tillers, or paddles that inject grout or dry cementitious powders as part of the mixing process. The Federal Highway Administration design manual for soil mixing helps to estimate the required amount of cementitious binder to produce a target design strength. However, it is biased towards inorganic soils and only mentions caution when confronting organic soils which usually come with a high water table, moisture content and void volume.

The Swedish Deep Stabilization Research Centre …

Three-Dimensional Interstitial Space Mediates Predator Foraging Success In Different Spatial Arrangements, Stephen Gregory Hesterberg

USF Tampa Graduate Theses and Dissertations

Habitat structure modifies the strength of predator-prey interactions, but it remains unclear how to describe the three-dimensional spatial arrangement of structural components in a way that consistently predicts outcomes. Interstitial space may provide a useful target for measurement, but most studies use only two-dimensional methods to describe 3D space, limiting their predictive power. Using a novel technology to produce identical components, this study tests whether the 3D interstitial space of oyster shell mimics modifies the ability of blue crabs (Callinectes sapidus) to capture their mud crab prey (Eurypanopeous depressus) in mesocosms and a variety of reef-associated …

Containment: A Failed American Foreign Policy And How The Truman Doctrine Led To The Rise In Islamic Extremism In The Muslim World, Christopher Jonathan Gerber

USF Tampa Graduate Theses and Dissertations

After World War II the United States, faced with the new Soviet threat of Communism, instituted the foreign policy known as “containment” in order to mitigate the threat to Western European states of Soviet expansionism. After the fall of Communism in the USSR in 1991 that policy was deemed, at once, a success and an anachronism. The power vacuum that the subsequent abandonment of that policy created was most notable in the Islamic states that had served as proxies in the Cold War against Communism. Both the backdrop of containment as well as the withdrawal of that policy served to …

Chemical Investigation Of Antarctic Marine Organisms & Their Role In Modern Drug Discovery, Jacqueline Lee Fries

USF Tampa Graduate Theses and Dissertations

The chemicals produced by biological systems, whether proteins, peptides, or terpenes, will always provide an intriguing topic for researchers. Invisibly controlling every aspect of nature, these molecules are responsible for life, evolution, and death. Specifically, here is described the secondary metabolites produced by Antarctic marine organisms as well as others, and how they are used to defend or attract other animals while potentially providing health benefits to mankind. This is done through collection, extraction, and separation of individual specimens. The respective mixtures of compounds after isolation are then analyzed via spectroscopic methods such as nuclear magnetic resonance spectroscopy, mass spectrometry, …

The Effects Of Processing Instruction On Chinese Learners' Acquisition Of Spanish Copulae, Wesley Curtis

USF Tampa Graduate Theses and Dissertations

Processing instruction (PI) is a language teaching technique based upon the model of input processing developed by VanPatten (1993, 1996, 2002, 2004). The present study investigated the effects of PI as well as two other experimental conditions (traditional instruction and control) on the acquisition of the Spanish copulae ser and estar by 66 Chinese university students enrolled in a blended (partially presential and partially online) fourth-semester language course. The PI treatment condition included non-paradigmatic grammar explanations, processing strategies designed to help learners avoid commiting errors they may be predisposed to make, and structured input activities which eliminate redundant features of …

Label Noise Cleaning Using Support Vector Machines, Rajmadhan Ekambaram

USF Tampa Graduate Theses and Dissertations

Mislabeled examples affect the performance of supervised learning algorithms. Two novel approaches to this problem are presented in this Thesis. Both methods build on the hypothesis that the large margin and the soft margin principles of support vector machines provide the characteristics to select mislabeled examples. Extensive experimental results on several datasets support this hypothesis. The support vectors of the one-class and two-class SVM classifiers captures around 85% and 99% of the randomly generated label noise examples (10% of the training data) on two character recognition datasets. The numbers of examples that need to be reviewed can be reduced by …

An Evaluation Of The Effectiveness Of A Social Skills Application For Children Who Are Homeless, Emily Baton

USF Tampa Graduate Theses and Dissertations

Researchers have found children who are homeless are twice as likely to develop learning disabilities when compared with non-homeless children and three times as likely to develop emotional and behavioral problems (Bessuk et al., 2014). Additionally, homeless children are more likely to have deficits in regards to social skills (DiBiase & Waddell, 1995; National Child Traumatic Stress Network Homelessness and Extreme Poverty Working Group, 2005), however no known research has specifically explored increasing social skill deficits among homeless children. The purpose of the current research was to a) extend the research on using technology to teach social skills to homeless …

It’S More Than Just Changing Your Password: Exploring The Nature And Antecedents Of Cyber-Security Behaviors, Rachel Christine Dreibelbis

USF Tampa Graduate Theses and Dissertations

Organizations have become increasingly concerned with developing and protecting their information security systems. Despite attempts to secure the information infrastructure, employees inside of organizations remain the largest source of threat to information cyber-security. While previous research has focused on behavioral and situational factors that influence cyber-security behaviors, the measurement of cyber behaviors and their relationship to other performance variables is poorly understood. The purpose of the present study is to 1) determine the underlying factor structure of a cyber-security behavior scale, 2) assess if individual personality traits predict four types of cyber-security behaviors: security assurance, security compliance, security risk, and …

An Investigation Of The Effects Of Chemical And Physical Weathering On Submerged Karst Surfaces, Bryan Charles Booth

USF Tampa Graduate Theses and Dissertations

Reports an investigation of the effects of chemical and physical weathering on submerged karst surfaces that pairs laboratory studies with computer modeling studies. The first study attempts to quantify the production of carbonate fines; soluble sediments produced by the incomplete dissolution of karst minerals during chemical weathering.

Neurophysiological Activity Related To Speech Production: An Erp Investigation, Adithya Chandregowda

USF Tampa Graduate Theses and Dissertations

The event related potential (ERP) technique is enjoying widespread application in neurophysiological research due to its fine temporal resolution. Of relevance to this study are ERPs related to voluntary movements. The precision with which movement related processes could be recorded using the ERP technique was demonstrated by Gilden, Vaughan and Costa (1966) and Kutas and Donchin (1974, 1977, and 1980) who found that the readiness potential (RP) immediately preceding hand movement was larger over the hemisphere contralateral to the responding hand. Given that left hemisphere controls right hand movements and vice versa, their findings confirmed that the lateralized readiness potential …

The Relationship Of Childhood Stress To Adult Health And Mortality Among Individuals From Two U.S. Documented Skeletal Collections, Late 19Th To Early 20Th Centuries, Rhonda Coolidge

USF Tampa Graduate Theses and Dissertations

Although the association between social inequality and poor adult health is well established, the mechanisms by which inequality is translated into poor adult health are less clear. Increasingly, evidence suggests that many adult health problems and health disparities have their origins in early life; the developmental origins of health and disease (DOHaD) hypothesis provides an explanatory mechanism linking adverse early life conditions with permanent structural or functional changes that increase the risk for disease. This hypothesis is consistent with bioarchaeological research noting reduced lifespan among individuals exhibiting signs of childhood stress.

The principal aim of this dissertation is to contribute …
