Response To Bullying (Rtb): Behavioral Skills And In Situ Training For Individuals Diagnosed With Intellectual Disabilities, Rebecca Lynn Stannis

USF Tampa Graduate Theses and Dissertations

Bullying is a continuing problem for adults with intellectual disabilities who live in group homes and attend adult day training settings together. Many different intervention approaches have been reviewed. Most research in this area focuses on bullying in schools with typically developing children, and therefore, a need for effective behavioral interventions for adults with intellectual disabilities still remains. Previous research has found success in teaching safety skills to a variety of populations using behavioral skills training (BST) and achieving generalization of these skills using in situ training (IST). This study evaluated BST to teach a response to bullying (RtB) to …

The Evaluation Of Tablets To Increase Compliance And Decrease Problem Behaviors In Children Diagnosed With Autism Spectrum Disorder, Hongchau Vo

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to replicate the effects of the study by Neely et al. (2013) and also determine if the tablet served as a reinforcer for three participants with escape maintained behaviors. A multiple baseline with an alternating treatment design was utilized in the first phase in which academic work was completed on either traditional materials or the tablet. The following phases for each participant were dependent on the prior phase, with a final choice phase. All participants showed lower levels of problem behaviors and higher levels of compliance when tablets were introduced contingent upon completing work. …

Is Nubia Plate Rigid? A Geodetic Study Of The Relative Motion Of Different Cratonic Areas Within Africa., Mary Wambui Njoroge

USF Tampa Graduate Theses and Dissertations

The Nubia plate is normally considered to be a rigid plate and as such used in the realization of terrestrial reference frame. Gondwana breakup plate reconstruction, the Cameroon volcanic line, seismicity, and the morphology of the Okavango rift zone (ORZ) suggest the presence of internal deformation within the Nubia plate. To test this hypothesis, six different reference frames were developed from the velocity field of three individual regions (West, Central and South), and of different combinations of them (West+Central, South+Central, and Nubia as a whole). The residual velocities with respect to these references frame help us understand the presence of …

He_Rtland: The Violence Of Neoliberalism, Hector Sotomayor

USF Tampa Graduate Theses and Dissertations

Perhaps, under the consciousness of today, “neoliberalism” has defined our world during the previous and current centuries more than any other socioeconomic system. But the evolution of this ideology, which initially aimed to enhance, or rather, reinvent capitalism and individual freedom, has, in essence, induced an unrecognized problem. I argue that neoliberalism is the catalyst for much of the hostility in this globalized society where tensions and poverty are casualties of individual and corporate prosperity. Because of this revelation, I argue that neoliberalism inadvertently instills violence that is both unseen and gendered. In order to formulate my argument, I introduce …

Let’S Move! Biocitizens And The Fat Kids On The Block, Mary Catherine Dickman

USF Tampa Graduate Theses and Dissertations

This project analyzed First Lady Michelle Obama’s Let’s Move! campaign for how it constructs obesity and health. Let’s Move! is a national internet-based campaign to end childhood obesity. The literature on Let’s Move! is limited and focuses on the privatization and corporatization of children’s physical education in public schools. Taking an intersectional approach to critical fat studies, I use critical discourse analysis to investigate how the language used in the Let’s Move! campaign (re)enforces and (re)signifies cultural notions of fat as a social problem – specifically that fat bodies are diseased, unproductive, and a financial burden. I maintain that the …

Investigation Of The Effects Of Impulsivity And Executive Function On A Complex Prospective Memory Task, Emily Kellogg

USF Tampa Graduate Theses and Dissertations

Prospective memory is colloquially known as “remembering to remember” and refers to forming an intention in the present time to fulfill at some point in the future. It has previously been studied within the context of executive functioning (i.e., purposive and goal directed behavior) and impulsive behaviors (e.g., gambling, risk seeking) within clinical populations. This study sought to further elucidate the relationships of impulsivity and executive functions on prospective memory in a non-clinical population. One hundred and nine undergraduates completed the UPPS-P impulsivity self-report questionnaire, three cognitive tasks measuring components of executive function, (i.e., planning, inhibition, and switching), and a …

To "Plant Our Trees On American Soil, And Repose Beneath Their Shade": Africa, Colonization, And The Evolution Of A Black Identity Narrative In The United States, 1808-1861, Edward Jason Vickers

USF Tampa Graduate Theses and Dissertations

This work explores the role that ideas about Africa played in the development of a specifically American identity among free blacks in the United States, from the early nineteenth century to the Civil War. Previous studies of the writings of free blacks in the Revolutionary period, and of the American Colonization Society (ACS), which was devoted to removing them back to an African homeland, have suggested that black discussions of Africa virtually disappeared after 1816, when the colonization movement began. However, as this work illustrates, the letters, books, newspapers, and organizational records produced by free blacks in the antebellum era …

Evaluating Preference For And Effectiveness Of Telehealth And In-Person Parent Training, Jennifer Michelle Stich

USF Tampa Graduate Theses and Dissertations

Telehealth provides an alternative delivery form of parent training that allows practitioners to disseminate information and feedback at a distance. Telehealth can be as effective as in-person training (Wacker et al., 2013a; Wacker et al., 2013b; Vismara et al., 2009). Despite most telehealth studies indicating high satisfaction, research on patient satisfaction using telehealth has depended mostly on survey instruments, which limits definitive conclusions and may not translate into actual use or selection (Whitten & Love, 2005). The primary purpose of this study was to evaluate a procedure for identifying parent preference of in-person or telehealth training modalities. Secondary purposes were …

Evaluating Corrosion Resistance Of Reinforcing Steel In A Novel Green Concrete, Andrea Carolina Ramirez

USF Tampa Graduate Theses and Dissertations

Reinforced concrete structures are expected to have a long service life with minimal maintenance. Corrosion of reinforcing steel is a major factor in reducing concrete structure lifespan, as corrosion products occupy a larger volume than that of the consumed steel and generate tensile stresses that crack the concrete cover. Procedures to control corrosion in traditional concrete, which is made with Portland-cement (PC), have been well established. However, in recent years novel concrete materials based on alternatives to normally cured PC have been developed in response to global needs to reduce greenhouse gases emissions. In particular, a promising new cement has …

Linking Insomnia And Suicide Ideation: The Role Of Socio-Cognitive Mechanisms In Suicide Risk, Melanie Lauren Bozzay

USF Tampa Graduate Theses and Dissertations

Despite what is known about predictors of suicide risk and consequences of insomnia, research has yet to delineate mechanisms that may explain the known relationship between insomnia symptoms and suicide risk. There is some disagreement in the literature regarding whether this relationship could be primarily explained by recent depressive symptoms, or whether there may be other explanatory factors related to sleep deficits. The present study addressed this contention in the literature by examining 1) whether socio-cognitive variables (e.g. fatigue, appraised social problem-solving ability, and hopelessness) explained this insomnia-ideation relationship, and 2) whether these variables contributed some explanatory variance in suicide …

Adolescent Females With High-Functioning Asd: Self And Mothers’ Perspectives Of Their School And Social Experiences, Lindsey Land

USF Tampa Graduate Theses and Dissertations

Although the prevalence of Autism Spectrum Disorder (ASD) is currently 1 in 68 (Centers for Disease Control, 2015) and research in this area is growing, high-functioning individuals on the spectrum are often overlooked. This is because of their relatively milder symptoms. The recent collapse of Asperger Syndrome (AS) with autism in the most recent version of the Diagnostic and Statistical Manual (DSM-5; APA, 2013) also has obscured the differences that may exist between those with higher vs. lower levels of functioning. Among youth with High-Functioning Autism Spectrum Disorder (HFASD), girls are a particularly understudied and potentially vulnerable group. Previous research …

In Situ Studies Of Limestone Dissolution In A Coastal Submarine Spring, Rachel Marie Schweers

USF Tampa Graduate Theses and Dissertations

Limestone dissolution in karst environments is likely due to geochemistry of the water, the actions of microbial communities, and the effect of water flow. We explored the rate of limestone dissolution and will examine here the microbial communities associated with the limestone. A conduit within the brackish cave, Double Keyhole Spring, on the coast of central west Florida was the site of the experiment. PVC pipes (5cm x 16cm) were filled with crushed limestone that was screened to a 1.9cm – 2.54cm size range. There were three treatments (5 replicates each): Control - sealed autoclaved controls with limestone and conduit …

Kelvin Probe Electrode For Field Detection Of Corrosion Of Steel In Concrete, Leonidas Philip Emmenegger

USF Tampa Graduate Theses and Dissertations

While the Kelvin Probe (KP) has been used in a variety of surface scanning applications, the use of the KP in reinforced concrete structures to detect corrosion has been pioneered by previous work performed at the University of South Florida. However, in that work, the scale and construction of the probes was not suited to use in the field. This is primarily attributable to the small operating disk-to-concrete gap which would make the probe unable to accommodate road conditions, such as irregularities in the grading of the road, and local pitting of the surface. Therefore, it was important to investigate …

Emergent Insect And Neotropical Migratory Bird Interactions And Responses To Habitat, Hydrology, And Progressive Urbanization In The Tampa Bay Region, Nathaniel Lee Goddard

USF Tampa Graduate Theses and Dissertations

The growing human population threatens the many of the earth’s biological systems. In the last 600 years extinction rates risen from 1 extinction per million species per year (E/MSY) in the 1400’s to 50 E/MSY today. During this time period 1.5% of all known birds have gone extinct, because they could not adapt quickly enough to human mediated changes. The goal of this dissertation was to determine how urbanization and anthropogenic services needed to support urban areas impact cypress dome wetland aquatic insect and migratory bird populations that depend on them. In Central Florida cypress dome hydroperiods are driven by …

Implementation Of Medicaid Managed Long-Term Services And Supports For Adults With Intellectual And/Or Developmental Disabilities: A State’S Experience, Heather Jeanne Williamson

USF Tampa Graduate Theses and Dissertations

Background: Individuals with intellectual and/or developmental disabilities (IDD) are experiencing longer life expectancies with the majority requiring the ongoing support of family caregivers into adulthood. Medicaid is the primary funding source for supports and services for adults with IDD. Growing Medicaid expenditures and goals to improve quality of care are driving more states to move their Medicaid fee-for-service programs into a managed care model. The stated goals of Medicaid managed long-term services and supports (MLTSS) are to improve care coordination and access to care while controlling costs, but the evidence regarding these outcomes is limited and mixed. Given the level …

Applying Voronoi Tessellations As A Non-Orthogonal Grid Methodology To Inform Public-Private Mix Efforts In Nigeria: An Examination Of The Distribution Of Private Healthcare Providers In Six States And The Covariates Underlying Their Utilization, Trinadh Dontamsetti

USF Tampa Graduate Theses and Dissertations

TB care and prevention is led by the public sector, but many TB symptomatics first seek care in the private sector, highlighting the importance of engaging these facilities. This report examines basic TB epidemiology (such as the gap in case finding that could be addressed in part via private sector activities), health-seeking behaviors (HSB) and diagnostic delays, the size of the private sector, activities of professional societies, and financing. It examines the potential utility of integrating Voronoi tessellations as a GIS-based method for informing and improving Public-Private Mix (PPM) efforts throughout six states in Nigeria. Further, it explores a potential …

Passive Symmetry In Dynamic Systems And Walking, Haris Muratagic

USF Tampa Graduate Theses and Dissertations

The ubiquitous nature of symmetry lends itself to be taken for granted, however the breath of research on symmetry encompasses several disciplines. In engineering, studies centered on symmetry often address issues in dynamic systems theory, robotics, and gait rehabilitation. This thesis presents findings on two specific topics dealing with passively induced symmetry; dissimilar rotating systems and human gait. Past studies on passive symmetry in dynamic systems often incorporate physical coupling or a controller. This thesis presents a technique to passively induce symmetry between two dissimilar systems that are not physically connected. This work also presents a human gait study consisting …

Using Auditory Feedback To Teach Dance Skills To Adults With Intellectual Disabilities, Aracely Abreu

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to evaluate the use of auditory feedback for teaching individuals with intellectual disabilities the “Mississippi Cha Cha Slide.” Participants consisted of six males ages 35 to 61. During baseline, line dance skills were low for all participants. During the auditory feedback intervention, the trainer used a clicker to reinforce dance steps and forward chaining to chain movements into a sequence. Once auditory feedback was implemented, line dance skills increased substantially for all participants. Generalization assessments for four of the participants resulted in performance levels similar to baseline and demonstrate the need for future training …

USF Tampa Graduate Theses and Dissertations

The primary objective of this work is to design a parking guidance system to reliably detect entering/exiting vehicles to a parking garage in a cost-efficient manner. Existing solutions (inductive loops, RFID based systems, and video image processors) at shopping malls, universities, airports etc., are expensive due to high installation and maintenance costs. There is a need for a parking guidance system that is reliable, accurate, and cost-effective. The proposed parking guidance system is designed to optimize the use of parking spaces and to reduce wait times. Based on a literature review we identify that the ultrasonic sensor is suitable to …

Getting Ahead: Socio-Economic Mobility, Perceptions Of Opportunity For Socio-Economic Mobility, And Attitudes Towards Public Assistance In The United States, Alissa Klein

USF Tampa Graduate Theses and Dissertations

In this research I first examine how Americans’ perceptions of what it takes to get ahead are influenced by their income and then compare those perceptions to measured levels of intergenerational socio-economic mobility. By better understanding these relationships I hope to gain insight into the paths people see to upward mobility, how this varies by income, and to what extent this belief is reflected in past mobility measurements. Additionally, I compare perceptions of what it takes to get ahead with responses regarding attitudes towards public assistance. The results of such a comparison could have important implications for public policy.

The …

Developing A Compiler For A Regular Expression Based Policy Specification Language, Cory Michael Juhlin

USF Tampa Graduate Theses and Dissertations

Security policy specification languages are a response to today's complex and vulnerable software climate. These languages allow an individual or organization to restrict and modify the behavior of third-party applications such that they adhere to the rules specified in the policy. As software grows in complexity, so do the security policies that govern them. Existing policy specification languages have not adapted to the growing complexity of the software they govern and as a result do not scale well, often resulting in code that is overly complex or unreadable. Writing small, isolated policies as separate modules and combining them is known …

Grounded in framing theory, this thesis presents a quantitative content analysis of newspaper reporting of the Hong Kong protests, also known as the Occupy Central Movement or the Umbrella Revolution, between September 28 and December 11, 2014. The political, economic and legal implications involved have made the protests one of the most newsworthy events in the history of Hong Kong since the transfer of its sovereignty from the United Kingdom to China in 1997. This study aims to examine the various frames used in the coverage of the protests in three major newspapers that operate within different political, economic and …

Blindcanseeql: Improved Blind Sql Injection For Db Schema Discovery Using A Predictive Dictionary From Web Scraped Word Based Lists, Ryan Wheeler

USF Tampa Graduate Theses and Dissertations

SQL Injections are still a prominent threat on the web. Using a custom built tool, BlindCanSeeQL (BCSQL), we will explore how to automate Blind SQL attacks to discover database schema using fewer requests than the standard methods, thus helping avoid detection from overloading a server with hits. This tool uses a web crawler to discover keywords that assist with autocompleting schema object names, along with improvements in ASCII bisection to lower the number of requests sent to the server. Along with this tool, we will discuss ways to prevent and protect against such attacks.

A Bat-Guano-Derived Δ15N And Δ13C Record Of Paleoenvironmental Change: Zidită Cave, Romania, Daniel Martin Cleary

USF Tampa Graduate Theses and Dissertations

Because nitrogen isotopes are fractionated along the soil-plant-insect-bat-guano pathway, it may be possible to reconstruct environmental and climatic changes reflected in the nitrogen isotopic composition of guano. A 1.5-m core of bat guano from Zidită Cave (western Romania) provides a record of climatic and anthropogenic influence on the regional nitrogen cycle and paleoenvironmental controls on nitrogen transforming processes. Increasing and decreasing trends of nitrogen isotopic composition (δ¹⁵N values) correspond well with changes in the influence of farming practices, deforestation, and forest expansion. These influences likely had a significant effect on the openness of the nitrogen cycle, resulting in …

USF Tampa Graduate Theses and Dissertations

Here we present a novel Smartphone-based colorimeter and demonstrate its application to the measurements of glucose and protein concentrations in biological samples. The key innovation of our approach was to combine powerful image processing encoded into a mobile phone application with a low cost 3D printed sample holder that allowed to control lighting conditions and significantly improved sensitivity. Different solutions with protein and glucose concentrations ranging from 0 to 2000 mg/dL were prepared and analyzed using our system. The Smartphone-based colorimeter always correctly classified the corresponding reagent strip pads, what confirms that it can be used as a low cost …

Dissolved Nutrient Distributions In The Gulf Of Mexico Following The Deepwater Horizon Oil Spill, Ashley Ann Parks

USF Tampa Graduate Theses and Dissertations

The Deepwater Horizon (DWH) oil spill in the Gulf of Mexico (GoM) in the spring of 2010 introduced 4.4 million of barrels of oil to the ecosystem. Some biodegradation of the oil occurs when microorganisms, particularly bacteria, metabolize the oil as a carbon source. During this process, the microbes also require nutrients for energy. An introduction of oil at this magnitude has the ability to induce large blooms of microbes, which in turn can affect nutrient concentrations. Microbial petroleum degradation decreases nutrient concentrations, whereas the microbial assimilation and decay of organic matter increase nutrient concentrations. This study assessed whether any …

Millennial-Scale Variability Of A Major East Antarctic Outlet Glacier During The Last Glaciation, Michelle Guitard

USF Tampa Graduate Theses and Dissertations

Ongoing retreat of Antarctica’s marine-based glaciers is associated with warm (~2° C) modified Circumpolar Deep Water intrusion onto the continental shelf, suggesting that Southern Ocean temperatures may influence Antarctic ice sheet stability. Understanding past cryosphere response to environmental forcing is crucial to modeling future ice sheet behavior. Of particular interest is the response of the East Antarctic Ice Sheet (EAIS), which stands to contribute ~20 m to global sea level. However, marine sediment sequences recording timing and variability of EAIS fluctuations through the last major climate shift, the Last Glacial Maximum (LGM), are either missing from the margin or have …

Ocean Forcing Of Quaternary East Antarctic Ice Sheet Evolution: An Ice-Proximal Sedimentary Perspective, Michelle E. Guitard

USF Tampa Graduate Theses and Dissertations

Antarctica and the Southern Ocean play a critical role in Earth’s climate system. Antarctica’s ice sheets contain enough ice to raise global sea level by ~58 m, and the Southern Ocean distributes climate signals and nutrients to the major ocean basins and the deep ocean. Antarctica’s largest ice sheet, the East Antarctic Ice Sheet (EAIS), was considered stable compared to those in West Antarctica and the Antarctic Peninsula because it was thought to be grounded above sea level. However, subglacial topography now reveals vast submarine basins and measurements of ice velocity in the Pacific sector indicate marine-terminating outlet glacier thinning …

Trust In People And Trust In Technology: Expanding Interpersonal Trust To Technology-Mediated Interactions, Evgeniya Evgenieva Pavlova Miller

USF Tampa Graduate Theses and Dissertations

Trust is necessary for human interactions. It provides the ability to participate in risky behaviors without engaging in a laborious risk-benefit analysis about the situation at hand. The introduction of information and communication technologies has brought about new ways of communicating (e.g., text messaging, video conferencing). Despite the benefits stemming from the ability to communicate through technology, the lower quality and quantity of communication cues exchanged during a technology-mediated interaction can hamper the development of trust.

This study examined the relationship between interpersonal trust and trust in technology during a technology-mediated dyadic interaction and aimed to determine whether interpersonal trust …
