Script Training For Adults Who Stutter, Courtney M. Rankin

USF Tampa Graduate Theses and Dissertations

Treatment for adulthood stuttering traditionally focuses on some combination of stuttering management and fluency management and may also target emotional and cognitive reactions to stuttering. However, long-term gains are often limited, and there is a need for continued development of approaches for mitigating impacts of stuttering. We know of no evidence-based therapy approaches designed to target functional communication in adults who stutter (AWS), despite widespread interest in improving functional communication in members of this speaker group. Script training is an intervention approach designed to improve accuracy and automaticity in functional communication. Script training was originally designed for use with adults …

The Effect Of Narrative Language Intervention On The Language Skills Of Children With Hearing Loss, Stephanie M. Raymond

USF Tampa Graduate Theses and Dissertations

Children with hearing loss have limited auditory access to their native language and struggle to develop appropriate language skills. These children consistently demonstrate less complex oral language output, smaller vocabulary inventories, and delays in overall communicative proficiency. With the extensive implications hearing loss has on language development, a child with hearing loss requires immediate access to appropriate and effective intervention to address deficits and curb long-term language delays. However, there is a paucity of research investigating the effects of various language intervention programs with children with hearing loss. Much of the existing research focuses on the consequences of a selected …

Promoting L2 Idiomatic Competence Among Chinese College Students Via Wechat, Zhengjie Li

USF Tampa Graduate Theses and Dissertations

Many second language (L2) scholars acknowledge that L2 idioms play a critical role in reading development as well as in communicative competence for L2 learners (Arnaud & Savignon, 1997; Barfield & Gyllstad, 2009; Conklin & Schmitt, 2008; Howarth, 1998; Liontas, 2017; Littlemore, Chen, Koester, & Barnden, 2011). Echoing the current trends of Computer Assisted Language Learning (CALL), much research has been done to underscore how L2 idiom learning can be infused with instructional technologies to promote L2 learners’ idiomatic competence (see Luk & Ng, 1998; Nakata, 2011; Yang & Xie, 2013). However, what remains underexplored is the ways that L2 …

USF Tampa Graduate Theses and Dissertations

By working with an anti-human trafficking organization in Sarasota, Florida, and sex-worker activists based in St. Petersburg, Florida, this research focuses on the process by which trafficking victims and sex workers are identified and dealt with by the criminal justice system and NGO rehabilitation programs. The study focused on understanding how stakeholders decide between identifying someone as a criminal or a victim of sex trafficking and how women identify themselves and subjectively experience their interaction with the criminal justice system and a faith-based rehabilitation program. By exploring the victims’ process of going through the criminal justice system, this study problematizes …

Increasing Engagement And Academic Performance Of Children With Autism Spectrumdisorder And Attention Difficulties: Do Fidget Spinners Help?, Melanie Byrne B.S.

USF Tampa Graduate Theses and Dissertations

Children with varying exceptionalities including ADHD, Autism Spectrum Disorder, and other learning disabilities often struggle with attention deficits. The persistence of alternative non-behavioral approaches in classrooms to address this deficit presents the need for more research and education about these interventions. Specifically, the fidget spinner is a newer intervention which currently has no empirical evidence to support its use in the classroom setting. The purpose of this study was to examine the effects of fidget spinners on increasing engagement and academic comprehension in a whole classroom environment. A multiple baseline across participants design was used with six children with varying …

Synthesis, Discovery And Delivery Of Therapeutic Natural Products And Analogs, Zachary P. Shultz

USF Tampa Graduate Theses and Dissertations

Small molecule drug discovery relies heavily on synthetic organic chemistry to develop novel chemical entities that elicit desirable therapeutic effects. The development of targeted chemical syntheses is of paramount importance to access molecules for biological evaluation and is usually considered the bottleneck in most drug discovery campaigns. Targets for chemical syntheses commonly draw inspiration from molecules of natural origin. Nature harbors a wealth of chemical diversity that has established itself over millions of years through chemical and biological evolution. Organisms have an inherent ability to protect themselves from predators and harmful environments. In doing so, many of them evolve to …

An Optimal Medium-Strength Regularity Algorithm For 3-Uniform Hypergraphs, John Theado

USF Tampa Graduate Theses and Dissertations

Szemere´di’s Regularity Lemma [32, 33] is an important tool in combinatorics, with numerous appli- cations in combinatorial number theory, discrete geometry, extremal graph theory, and theoretical computer science.

The Regularity Lemma hinges on the following concepts. Let G = (V, E) be a graph and let ∅ /= X, Y ⊂ V be a pair of disjoint vertex subsets. We define the density of the pair (X, Y ) by d_G(X, Y ) = |E[X, Y ]|/(|X||Y |) where E[X, Y ] denotes the …

Morphology And Detection Of Corrosion On Stainless Steel Reinforcement In Concrete, Julio J. Saire Yanez

USF Tampa Graduate Theses and Dissertations

Stainless steel (SS) has emerged as an alternative corrosion-resistant reinforcement in concrete instead of the commonly used carbon steel (CS). The biggest advantage of SS is that it takes more time for corrosion to initiate than for CS. An additional benefit from the use of SS in concrete may be derived from the period after the corrosion started until the concrete structure reaches a limit state. This period is called corrosion propagation stage (CPS) and it has been hardly studied in SS reinforced structures. The duration of this period could be related, among other factors, to the morphology of corrosion …

Sorption Of Benzene, Tolueneand Ethylbenzeneby Plasticized Pema And Pema/Pmma Sensing Films Using Aquartz Crystal Microbalance (Qcm) At 298.15k, Deekshitha Adapa

USF Tampa Graduate Theses and Dissertations

Detection of volatile organic compounds (VOC’s) in the environment is important for human health and wellness. Long term exposure of certain VOC’s like benzene, toluene, ethylbenzene and xylene (BTEX) has a severe effect on human health. There are techniques such as gas chromatography, photo ionization, and mass spectroscopy that are time consuming, require gas sampling and are ineffective in real time sensing in air. Acoustic wave devices such as surface acoustic wave (SAW) devices can be used for sensing BTEX compounds in both vapor and liquid phase. The quartz crystal microbalance (QCM) is a low-frequency acoustic wave device, which can …

Three Theorists On Religious Violence In An Islamic Context: Karen Armstrong, Mark Juergensmeyer, And William T. Cavanaugh, Ayse Camur

USF Tampa Graduate Theses and Dissertations

Religion is often invoked as a driving force behind violence, disentangled from political, social, and economic reasons. In this thesis, we will be exploring the viewpoints of three prominent religious thinkers in investigating the principal causes behind what is called religious violence. The works of Karen Armstrong, Mark Juergensmeyer, and William T. Cavanaugh are considered as theoretical frameworks for understanding violence in an Islamic context. While Armstrong argues that the root cause of violence can be traced back to economic, political, and cultural reasons, Juergensmeyer contests that religion is the most important cause underlying all violence. In their analyses, both …

Evolutionary Dynamics Of Influenza Type B In The Presence Of Vaccination: An Ecological Study, Lindsey J. Fiedler

USF Tampa Graduate Theses and Dissertations

Understanding the evolutionary dynamics of influenza type B in human hosts is a public health concern as we strive to minimize the disease burden in seasonal epidemics. Vaccination is considered the best defense against contracting influenza, and everyone over the age of 6 months is advised to get vaccinated before each season. The effect that vaccine-acquired immunity has on the evolution of influenza B remains unclear. In the U.S., vaccine-uptake is irregular across the states, and the differing coverages present an opportunity to study how vaccination influences viral evolution. This thesis analyzes the evolutionary patterns of influenza B in the …

Threats To Teaching: An Investigation Into The Constructs Of Compassion Fatigue In The Classroom, April M. Steen

USF Tampa Graduate Theses and Dissertations

A group of suburban/rural general and special education teachers (n = 260) responded to an electronic survey. The survey was designed to measure the prevalence of an under researched area of compassion fatigue and compassion satisfaction among teachers working in suburban/rural public schools. The current study hypothesized that the relationship among compassion fatigue, compassion satisfaction, demographic variables, and teacher stress factors (time management, discipline, motivation, professional distress, and professional investment) would correlate with an increase in compassion fatigue (burnout and secondary traumatic stress) for general and special education teachers working in suburban/rural public schools; furthermore, it predicted a positive correlation …

Cubesat Constellation Design For Intersatellite Linking, Michael T. White

USF Tampa Graduate Theses and Dissertations

This thesis investigates the concept of controlling a CubeSat constellation in low-Earth orbit. Low-Earth orbits are considered because the torque used for satellite control is supplied with magnetorquers, and the closer the satellite is to Earth’s magnetic field the more control gain can be supplied. Also, this is the expected orbit altitude of future CubeSat constellations to enable communications.

Controlling a CubeSat relies on attitude determination. This means being able to estimate its attitude relative to a given reference frame. To determine the attitude, we propose to use a star tracker and a Kalman filter. A star tracker scans the …

Quantifying The Friedreich Ataxia Rating Scale And The Functional Performance Measures, Chelsea Rene Davis

USF Tampa Graduate Theses and Dissertations

Friedreich Ataxia (FA) is a debilitating autosomal-recessive neurodegenerative disorder which is characterized by ataxia of all four limbs, difficulty walking, areflexia, and dysarthria. Further complications of FA include diabetes, scoliosis, and hypertrophic cardiomyopathy. Approximately three-quarters of people with FA have onset before the age of 25 and in most instances, affected individuals will require the use of a wheelchair within ten years after symptoms emerge.

The current advancements in clinical trials have escalated the developmental demand for a scale which validates adjustments in FA. The Friedreich Ataxia Rating Scale (FARS) is a disease-specific semi-qualitative assessment which includes three subscales (functional …

"It's Not Addiction Until You Graduate": Natural Recovery In The College Context, Breanne I. Casper

USF Tampa Graduate Theses and Dissertations

Natural recovery is inhibition or moderation of problematic substance use without employing the use of formal addiction services. A neuroanthropological approach to natural recovery highlights the importance of both social and biological aspects of achieving this "self" led process of change. Throughout this project I take a critical anthropological approach to natural recovery, which explores a more holistic conception and historically situated view of current natural recovery theory. This research project employs a neuroanthropological perspective to assess how college students perform natural recovery. Using ethnographic methods, which highlight the social and physical experience of moderation, I discuss how students negotiate …

Prioritizing Rehabilitation Of Sanitary Sewers In Pinellas County, Fl, Jesse T. Hillman

USF Tampa Graduate Theses and Dissertations

Following large rain events, extraneous freshwater contributions known as inflow and infiltration (I/I) bypass the storm sewer and enter the sanitary sewer system. In areas with a high water table, like Pinellas County and the surrounding Tampa Bay area, a majority of the wastewater infrastructure is submerged year round exacerbating the rate of groundwater infiltration. This excess flow overloads the existing wastewater infrastructure leading to sanitary sewer overflows (SSOs). These SSOs result in serious problems for municipalities and utilities across the country.

This study was performed in order to assist Pinellas County Utilities in rehabilitating their southern sewer system. To …

Functional Characterization Of The Ovarian Tumor Domain Deubiquitinating Enzyme 6b, Jasmin M. D'Andrea

USF Tampa Graduate Theses and Dissertations

The posttranslational modification ubiquitination is major regulatory mechanism used throughout cell signaling pathways such as cell cycle regulation and the DNA damage response. As such, the E3 ligases and their deubiquitinating enzyme counterparts, which conjugate and deconjugate ubiquitin to and from protein substrates respectively, must be tightly regulated to prevent aberrant cellular behaviors that could lead to diseases such as cancer.

Of the five families of deubiquitinating enzymes, the Ovarian Tumor Domain (OTU) family is fairly unique and under-studied; many of its family members hold a linkage specificity to certain ubiquitin chains and a number of them have been implicated …

USF Tampa Graduate Theses and Dissertations

Secure vehicular communication is a critical factor for secure traffic management. Perfect security in intelligent transportation systems (ITS) has solid and efficient intrusion detection systems (IDS). In this paper, we consider false data injection attacks and distributed denial-ofservice attacks (DDoS), especially the stealth low-rate DDoS attacks, targeting the integrity and availability, respectively, in vehicular ad-hoc networks (VANET). Novel statistical intrusion detection and mitigation techniques are proposed for the considered attacks. The performance of the proposed methods are evaluated using a traffic simulator and a real traffic dataset. Comparisons with the state-of-the-art solutions clearly demonstrate the superior performance of the proposed …

Autonomous Monocular Obstacle Detection For Avoidance In Quadrotor Uavs, Panos Valavanis

USF Tampa Graduate Theses and Dissertations

Unmanned Aircraft Systems (UAS) research and development and applications have witnessed unprecedented levels of growth in the past two decades. Although military applications have dominated the market, it is anticipated and expected that civilian and public domain applications will be dominant in the future. Consequently, gradual and timely integration of unmanned aviation into the National Airspace System (NAS) is a real challenge, and roadmaps towards achieving full integration are already in place in the US, Canada, Australia, South Africa and European Union (EU). However, before com- plete integration of manned-unmanned aviation, additional challenging problems need to be addressed and solved, …

Effect Of Hyperoxia On Type-1 Diabetic Mouse Model, Samuel Ignatious Bolleddu

USF Tampa Graduate Theses and Dissertations

Administration of Hyperoxia (>90 % oxygen) is a pervasive intervention to supplement respiratory needs in patients admitted in ICU/critical care units. Current literature suggests that prolonged use of Hyperoxia therapy is directly associated with in-hospital mortality. The exact reason for this high mortality under Hyperoxia is unknown. Recent explorations in Dr. Panguluri lab identified that dysregulation of Kv channels plays a vital role in the pathophysiology of Hyperoxia-induced pulmonary and cardiac complications using animal models. The proposed research will focus on the part of Hyperoxia in generating cardiotoxicity and ventricular remodeling in the type-1 diabetes patients using the Akita, …

Supervision In Every Breath: Enacting Zen In An Elementary Education Teacher Program, Steven R. Haberlin

USF Tampa Graduate Theses and Dissertations

The field of teacher education is in tumultuous times. Criticisms and questions about teacher preparation have led to calls for reform, including grounding teacher preparation programs in clinically rich experiences. Responsible for preparing these teachers, university- based supervisors are under added pressure to provide opportunities that connects theoretical knowledge with field experience. Complicating matters, views of supervision continue to evolve and remain divided, creating uncertainty over how to best approach the role. In light of these challenges, I argue in this study that current conceptions of supervision need to be reevaluated and expanded by entertaining new views, namely those from …

Density-Mediated Interactions Are Stronger But More Variable Than Trait-Mediated Interactions In Predator–Prey Systems, Travis M. Flock

USF Tampa Graduate Theses and Dissertations

Theoretical and empirical considerations of predator-prey dynamics have sought to determine the dominant of two effects exerted by predators onto prey: consumptive effects of predators and non-consumptive, or trait-mediated, effects. Many studies have identified trait-mediated interactions (TMIs) in diverse taxa, and meta-analyses of these studies found that prey population dynamics are as strongly – if not more strongly – affected by TMIs as density-mediated interactions (DMIs). Since then, there is now an expanded primary literature, and given this potential for new insight on the direct and indirect effect of predators on prey, the cost of traits involved in TMIs relative …

Steady State Hydroplaning Risk Analysis And Evaluation Of Unsteady State Effects, Menna Yassin

USF Tampa Graduate Theses and Dissertations

Hydroplaning is a major concern on high speed roadways during heavy rainfall events. Hydroplaning tools are widely used by designers to reduce their roadway’s hydroplaning potential, therefore reducing the possibilities of severe crashes. This dissertation presents two methodologies for improving the prediction of hydroplaning potential.

The first phase focused on improving an existing widely used software called PAVDRN. Using multiple datasets from the Florida Department of Transportation, the author filtered the data using specific criteria to leave only truly dynamic hydroplaning crashes. The author then evaluated PAVDRN’s prediction capabilities and assessed its reliability in predicting a hydroplaning crash. Using past …

Characterization Of Geogrid Reinforced Ballast Behavior Through Finite Element Modeling, Bugra Sinmez

USF Tampa Graduate Theses and Dissertations

Recently, the railway pavement structure system, as an integral part of the transport infrastructure, has been under fast development in some countries such as China, Turkey, and some European Union countries, particularly for the use of high-speed trains. In designing and constructing the railway pavement structure, it is necessary to take into account the infrastructure demand of the High-Speed Railway Lines (HSRL). Compared to traditional railway trains, HSRL can cause more significant problems to the ballast or base layer of commonly used ballasted railway pavements. The deteriorated ballast or base layer may further result in substructure degradation that may cause …

The study was conducted to add to the literature on project-based learning. Research on the steps a teacher takes to enact project-based learning can enhance …

Using Predicted Heat Strain To Evaluate Sustainable Exposures, Samantha L. Thacker

USF Tampa Graduate Theses and Dissertations

The most commonly used exposure assessment for heat stress is based on Wet Bulb Globe Temperature (WBGT), and the limits are based on empirical relationships that demonstrate a sustainable exposure. The ISO 7933 (2017) describes Predicted Heat Strain (PHS), which is a rational model for heat stress assessment that is used to assess time-limited exposures. Investigators have examined PHS validity under a variety of time-limited conditions. The purpose of this paper is to evaluate if PHS can predict sustainable exposures.

The data used for this study were from two previous heat stress studies using a progressive heat stress protocol. The …

Measuring Flowering Phenology And Its Consequences: A Systematic Review, Samantha M. Mangum

USF Tampa Graduate Theses and Dissertations

Despite growing interest in flowering phenology among ecologists, as reflected by an increase in the number of papers, there is little information on how studies typically measure and describe a plant’s flowering phenology. The focus of this study was the literature on flowering phenology and the approaches researchers have taken to quantify flowering phenology. Initially, a comprehensive description of the breath of literature on flowering phenology was produced. From there, I described the current research on flowering phenology: the year that the studies were published, the locations of the studies, and the particular biomes where the studies were performed. The …

Disentangling The Impact Of Poor Sleep From Depressive Symptoms On Emotion Regulation, Kimberly O'Leary

USF Tampa Graduate Theses and Dissertations

Depressive symptoms and sleep are both strongly associated with deficits in emotional functioning (Durmer & Dinges, 2005; van der Helm & Walker, 2010). Although sleep and depression are tightly intertwined, understanding their independent and conjoint impact on emotional functioning is imperative. Given the limitations of previous designs, the primary goal of this study was to examine the separate impact of poor sleep quality and depressive symptoms on emotion regulation. In order to accomplish this goal, we preselected groups on the basis of their sleep and depression profiles: individuals with mainly sleep problems (N = 30), individuals with mainly depressive symptoms …

Neuro-Correlates Of Word Processing Among Four-And-Five-Year-Old Children From Homes Varying In Socio-Economic Status, Wendy Olsen

USF Tampa Graduate Theses and Dissertations

A large body of research relates families’ socioeconomic status (SES) to child language development (Hoff & Tian, 2005). Results from these studies indicate preschoolers from low SES backgrounds may have underdeveloped linguistic foundations required for future academic success (Sirin, 2005; Lacouri & Tissington, 2011). These differences have been said to create a 30 million word-gap between the language experiences of low and middle to high SES children by the age of 3 years. Thus, children who come from lower SES backgrounds often lack the vocabulary knowledge used in school and in textbooks (Hart & Risley, 1995). One index of SES …

Contribution Of Sleep Disruption And Physical Inactivity To Fatigue In Survivors Of Allogeneic Hematopoietic Cell Transplant, Ashley M. Nelson

USF Tampa Graduate Theses and Dissertations

Background: Fatigue is a prominent quality of life concern among cancer patients who have undergone allogeneic hematopoietic cell transplantation (HCT). The high percentage of HCT patients reporting fatigue concerns warrants investigation into factors that may contribute to or alleviate fatigue. The present study sought to elucidate relationships among fatigue and behavioral factors including sleep disruption and sedentary activity.

Method: Allogeneic HCT recipients who were one to five years post-transplant were invited to participate in the present study. Participants wore an actigraph assessing sleep efficiency and sedentary behavior for one week, completed daily assessments of fatigue and sleep during the same …
