An Evaluation Of An Electronic Student Response System In Improving Class-Wide Behavior, Ashley Horne

USF Tampa Graduate Theses and Dissertations

A student response system is a technology that allows an entire classroom of students to respond to questions and receive immediate feedback from teachers during instruction. However, little research has examined the use of student response systems to support student behavior in elementary schools. This study focused on using an electronic student response system to improve class-wide behavior in two general elementary school classrooms. An ABAB and ABA reversal designs embedded within a multiple baseline design across classrooms was employed to evaluate the outcome of the intervention. Although limited, the results indicated that the classroom teachers implemented the electronic student …

Organized Crime In Insurance Fraud: An Empirical Analysis Of Staged Automobile Accident Rings, Chris Longino

USF Tampa Graduate Theses and Dissertations

The growing trend of insurance fraud continues to cost US consumers billions of dollars a year through increased premiums. In 2015, the Coalition Against Insurance Fraud estimated the cost of insurance fraud as being at least $80 billion dollars a year. Even though an increasing number of criminals are drawn to the low risk, high reward of insurance fraud, little criminological literature has explored this topic and the public remains relatively unaware of the extent of the problem.

One alarming aspect of insurance fraud is the involvement of organized criminal groups. These organized criminal enterprises are formed for the sole …

Reducing The Control Burden Of Legged Robotic Locomotion Through Biomimetic Consonance In Mechanical Design And Control, Caitrin Elizabeth Eaton

USF Tampa Graduate Theses and Dissertations

Terrestrial robots must be capable of negotiating rough terrain if they are to become autonomous outside of the lab. Although the control mechanism offered by wheels is attractive in its simplicity, any wheeled system is confined to relatively flat terrain. Wheels will also only ever be useful for rolling, while limbs observed in nature are highly multimodal. The robust locomotive utility of legs is evidenced by the many animals that walk, run, jump, swim, and climb in a world full of challenging terrain.

On the other hand, legs with multiple degrees of freedom (DoF) require much more complex control and …

Synthesis And Fabrication Of Graphene/Conducting Polymer/Metal Oxide Nanocomposite Materials For Supercapacitor Applications, Mohamad Khawaja

USF Tampa Graduate Theses and Dissertations

The rising energy consumption worldwide is leading to significant increases in energy production with fossil fuels being the major energy source. The negative environmental impact of fossil fuel use and its finite nature requires the use of alternative sources of energy. Solar energy is a clean alternative energy source; however, its intermittent nature is a major impediment that needs to be reduced or eliminated by the development of cost effective energy storage. Thermal storage in tanks filled typically with molten salt at elevated temperatures is widely used in concentrating solar power plants to generate electricity during periods of low daytime …

La Lengua Del Oyente: Some Effects Of Listener Language On Spanish-Speaking Preschoolers’ Verbal Behavior, Gerardo Castillo Ii

USF Tampa Graduate Theses and Dissertations

Bilingual children represent a large population of preschool and school-aged children in the United States. Challenges may arise when the verbal community in which a child spends most of his or her time does not reinforce his or her primary language. Previous research has shown that children adjust their language to match the language of their listener (Genesee, Boivin, & Nicoladis, 1996). It is possible that having a native-language communication partner at school would improve child engagement, as measured by child mean length of utterance and quantity of child initiations. The purpose of this study is to examine whether listener …

Reading In The Digital Era: Using Video Self-Modeling To Improve Reading Fluency In At-Risk Students, Monica Anestin

USF Tampa Graduate Theses and Dissertations

Reading fluency bridges the concepts of word recognition and reading comprehension, both of which are vital skills needed to become a successful reader. This study evaluated the impact of video self-modeling (VSM) on oral reading fluency in four upper elementary students at-risk for failing in reading. A multiple-baseline design across participants was used to evaluate the outcomes of the VSM intervention. The results indicate that VSM may have a positive impact on reading fluency of students at-risk for reading failure; the use of VSM was positively associated with increases in reading fluency in three of the four participants. The participant …

Keeping Up With The Grandkids: Using Tagteach To Train Baton Twirling Skills In Older Adults, Sarah Elizabeth Hester

USF Tampa Graduate Theses and Dissertations

Exercise has many physical, cognitive, and social benefits, but the majority of older adults do not meet the recommended level of physical activity (Centers for Disease Control and Prevention, 2014). TAGteach, which combines elements of both behavioral coaching and acoustical feedback, has been demonstrated as an effective way to teach athletic skills (Fogel, Weil, & Burris, 2010; Quinn, Miltenberger, & Fogel, 2015; Stokes, Luiselli, Reed, & Fleming 2010). However, none of the current research on teaching athletic skills targeted an older population. This study evaluated TAGteach in a multiple baseline across behaviors design as a method of teaching 4 basic …

Patient Populations, Clinical Associations, And System Efficiency In Healthcare Delivery System, Yazhuo Liu

USF Tampa Graduate Theses and Dissertations

The efforts to improve health care delivery usually involve studies and analysis of patient populations and healthcare systems. In this dissertation, I present the research conducted in the following areas: identifying patient groups, improving treatments for specific conditions by using statistical as well as data mining techniques, and developing new operation research models to increase system efficiency from the health institutes’ perspective. The results provide better understanding of high risk patient groups, more accuracy in detecting disease’ correlations and practical scheduling tools that consider uncertain operation durations and real-life constraints.

The Use Of Textural Kinetic Habitats To Mine Diagnostic Information From Dce Mr Images Of Breast Tumors, Baishali Chaudhury

USF Tampa Graduate Theses and Dissertations

Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) of the breast is a widely used non-invasive approach to gather information about the underlying physiology of breast tumors. Recent studies indicate that breast tumor heterogeneity may reflect the presence of different levels of cellular aggressiveness or habitats within the tumor. This heterogeneity has been correlated to the variations in the contrast enhancement patterns within the tumor apparent on gadolinium-enhanced DCE-MRI. Although pathological and qualitative (based on contrast enhancement patterns) studies suggest the presence of clini- cal and molecular predictive tumor sub-regions, this has not been fully investigated in the quantitative domain.

The …

Mediation And Moderation Analysis Of Nutrition, Inflammatory Biomarkers, And Cognition In Older Adults, Elizabeth Handing

USF Tampa Graduate Theses and Dissertations

Nutrition can be viewed as a modifiable factor related to maintaining and preserving health in older adults. Previous studies have found that nutritional factors can influence cognitive abilities, however few studies have examined macronutrients and micronutrients as they relate to cognitive functioning. Research has yet to examine the mechanisms related to nutrition, cognition and aging in an older adult population from a holistic and interactive perspective.

This dissertation examined three research questions to better understand the relationship between age, nutrition, cognition, and inflammatory biomarkers. First, is nutrition related to cognition beyond demographic factors? Do individual nutrients serve as mediators? Second, …

Using Auditory Feedback To Improve Dance Movements Of Children With Disabilities, Takema J. James

USF Tampa Graduate Theses and Dissertations

Research incorporating behavior analysis to improve sports performance has shown that various feedback types (e.g., video feedback, public posting) can increase skills. Recently, auditory feedback has been shown to be effective. The purpose of this study was to evaluate the utility of auditory feedback to improve dance movements of children with disabilities using an ABAB design embedded in a multiple baseline across participants design. The target behaviors were fundamental dance skills, individualized to each student, and scored using a task analysis to calculate the percentage of correct steps. The results showed that auditory feedback was valuable in increasing the specific …

Using Video Feedback To Increase Job Interview Skills For Young Adults With Developmental Disabilities, Jessica Lynn Moore

USF Tampa Graduate Theses and Dissertations

Individuals diagnosed with developmental disabilities often lack the skills needed to gain meaningful employment in the community. One crucial skill is interviewing as this is the first and often the only pre-job interaction an individual has with his or her employer. In a short interaction, the person must convey information about specific work history, employability, and a general impression of character. This study evaluated the effectiveness of video feedback in improving job interview behaviors for three young adults with developmental disabilities. The interview related-behaviors were appropriate greeting, responses to interview questions, and appropriate closing statement. The performance across the participants …

Design, Testing And Implementation Of A New Authentication Method Using Multiple Devices, Cagri Cetin

USF Tampa Graduate Theses and Dissertations

Authentication protocols are very common mechanisms to confirm the legitimacy of someone’s or something’s identity in digital and physical systems.

This thesis presents a new and robust authentication method based on users’ multiple devices. Due to the popularity of mobile devices, users are becoming more likely to have more than one device (e.g., smartwatch, smartphone, laptop, tablet, smart-car, smart-ring, etc.). The authentication system presented here takes advantage of these multiple devices to implement authentication mechanisms. In particular, the system requires the devices to collaborate with each other in order for the authentication to succeed. This new authentication protocol is robust …

Analysis Of Carbon Policies For Electricity Networks With High Penetration Of Green Generation, Felipe Feijoo

USF Tampa Graduate Theses and Dissertations

In recent decades, climate change has become one of the most crucial challenges for humanity. Climate change has a direct correlation with global warming, caused mainly by the green house gas emissions (GHG). The Environmental Protection Agency in the U.S. (EPA) attributes carbon dioxide to account for approximately 82\% of the GHG emissions. Unfortunately, the energy sector is the main producer of carbon dioxide, with China and the U.S. as the highest emitters. Therefore, there is a strong (positive) correlation between energy production, global warming, and climate change. Stringent carbon emissions reduction targets have been established in order to reduce …

A Composite Spatial Model Incorporating Groundwater Vulnerability And Environmental Disturbance To Guide Land Management, Johanna L. Kovarik

USF Tampa Graduate Theses and Dissertations

Research has long recognized and studied the dynamics of groundwater processes. More recently, groundwater dependent ecosystems (GDEs) are being recognized for their diversity and vulnerability to anthropogenic impact. Groundwater in karst landscapes presents a distinctive situation where flow through the subsurface often moves rapidly on the scale of days and weeks as opposed to years or millennia in other systems. This distinctive situation of karst systems and their vulnerability to human impacts necessitate an integrated and multifaceted approach for the management of these important resources. However, development of such an approach is complicated by the difficulty of obtaining detailed data …

Security Of Non-Volatile Memories - Attack Models, Analyses, And Counter-Measures, Jae-Won Jang

USF Tampa Graduate Theses and Dissertations

The unprecedented demand for performance in the latest technologies will ultimately require changes in the way we design cache. Emerging high density embedded memories such as Spin-Transfer Torque Random Access Memory (STTRAM) have emerged as a possible candidate for universal memory due to its high speed, low power, non-volatility, and low cost. Although attractive, STTRAM is susceptible to contactless tampering through malicious exposure to magnetic field with the intention to steal or modify the bitcell content. In this thesis, we explore various attack techniques on STTRAM and then propose a novel array-based sensor to detect the polarity and magnitude of …

An Assessment Of Retractions As A Measure Of Scientific Misconduct And Impact On Public Health Risks, Alison J. Abritis

USF Tampa Graduate Theses and Dissertations

Research misconduct has been generally considered a limited issue, occurring in a small percentage of research studies. Studies of the number of article retractions use retraction percentages to perpetuate the idea that research misconduct is not a common event, and use information in the retraction notice to quantify types of research misconduct and types or research error. However, retractions appear to be the wrong variable with which to assess misconduct rates and characteristics. Using final misconduct findings in hard science research from the Office of Research Integrity (ORI) for investigations closed from 1993 through 2013, the number of publications and …

Hesitation Rate As A Speaker-Specific Cue In Bilingual Individuals, Jamie Lynn Armbrecht

USF Tampa Graduate Theses and Dissertations

Hesitation use is common among all speakers, regardless of whether they are engaged in their dominant or non-dominant language (Fehringer & Fry, 2007; Reed, 2000). The question is whether a bilingual speaker will engage in the same types of hesitations in both languages. If hesitation patterns can be identified consistently across speakers regardless of language, their use as an acoustic cue for speaker identification may be possible. This study examines differences in hesitation use across languages and speaking contexts (reading vs. conversation) in bilingual speakers.

Twenty Spanish-English bilinguals (ages 19 -31 years) were tested as part of a larger speaker …

Obesity As A Disease: Effects On Weight-Biased Attitudes And Beliefs, Rheanna Nichole Ata

USF Tampa Graduate Theses and Dissertations

In June 2013, the American Medical Association (AMA) made the highly controversial decision to designate obesity a disease. Proponents predicted the decision would lead to reduced weight-related stigma, whereas opponents predicted designating a third of the population as “diseased” would exacerbate stigma. To determine the effects of defining obesity as a disease on explicit and implicit weight-biased attitudes and explicit weight-biased beliefs, female undergraduate students (N = 146) were randomly assigned to one of two groups: disease or lifestyle. Participants in the disease group (n = 71) were asked to read an article describing obesity as a disease caused by …

Altering Tian: Spirituality In Early Confucianism, Jacob Thomas Atkinson

USF Tampa Graduate Theses and Dissertations

This paper seeks to analyze the three earliest Confucian thinkers and the foundational texts associated with them. In studying these texts this paper attempts to discover how these early Confucian thinkers conceived of Tian. This paper claims the early Confucian thinkers did not make as radical of a departure from the Ancient Chinese religiosity as many modern scholars have suggested. It has often been asserted that the tradition presented by these Confucian thinkers was entirely humanistic, altogether separate from the Ancient Chinese religiosityThis paper contests such claims,instead insisting that the early Confucian spirituality still viewed Tian as God and that …

Representations Of Gatsby: Ninety Years Of Retrospective, Christine Anne Auger

USF Tampa Graduate Theses and Dissertations

Jay Gatsby, F. Scott Fitzgerald’s most famous character, has starred in a variety of stage and screen adaptations in the ninety years since he was first introduced in The Great Gatsby (1925). This dissertation explores the Gatsby character as depicted in six important adaptations of the novel, including two Broadway productions, Owen Davis’ 1926 drama and John Collins’ 2010s play, Gatz, and four major motion pictures: Herbert Brenon’s 1926 lost silent film (starring Warner Baxter); Elliott Nugent’s 1949 black and white film (starring Alan Ladd); Jack Clayton’s 1974 color film (starring Robert Redford); and Baz Luhrmann’s 2013 3-D film (starring …

Anticipatory Coarticulation And Stability Of Speech In Typically Fluent Speakers And People Who Stutter Across The Lifespan: An Ultrasound Study, Alissa Joy Belmont

USF Tampa Graduate Theses and Dissertations

This study uses ultrasound to image onset velar stop consonant articulation in words. By examining tongue body placement, the extent of velar closure variation across vowel contexts provides for the measurement of anticipatory coarticulation while productions within the same vowel context provide measurement of extent of token-to-token variation. Articulate Assistant Advanced 2.0 software was used to semi-automatically generate midsagittal tongue contours at the initial point of maximum velar closure and was used to fit each contour to a curved spline. Patterns of lingual coarticulation and measures of speech motor stability, based on curve-to-curve distance (Zharkova, Hewlett, & Hardcastle, 2011), are …

A Comparative Evaluation Of The Learner Centered Grading Debriefing Method In Nursing Education, Marisa J. Belote

USF Tampa Graduate Theses and Dissertations

The nursing discipline lacks a consensus on a best practice method for debriefing students following simulation-based training. A recognized, standardized method does not exist and various methods are utilized within the domain. The similarities between aviation and healthcare are well documented. Training members of both disciplines require standardization and methods of best practice. The aviation industry through the Federal Aviation Administration has found Learner Centered Grading (LCG) to be a successful educational format. The utilization of the LCG Debriefing method in simulation-based training is the standardized debriefing format for a technologically dynamic industry.

The aim of this research was to …

Validity Testing Of A Preschool Reading Screening Device For Pediatricians, Erika Elaine Blue

USF Tampa Graduate Theses and Dissertations

Despite efforts to improve access to early literacy intervention in the United States, there are still children entering kindergarten that are not adequately prepared for school and are unlikely to catch up to their peers (National Education Association, 2014). Preschool programs are actively involved in screening their students for potential literacy difficulties; however, there are children who do not attend preschool and may not have their literacy development assessed. One solution to this problem is to involve other individuals who routinely see preschool age children. Pediatricians are one such group as children come to them for their wellness visits and …

Exploring The Underlying Mechanisms Of Comorbid Adhd And Eating Disorders, Jennifer Rebecca Bleck

USF Tampa Graduate Theses and Dissertations

Evidence suggests comorbidity of ADHD and eating disorders (EDs) among females. Capitalizing on the comorbidity of ADHD and EDs and subsequent obesity could lead to improved prevention and treatment of all three conditions. However, additional information regarding the comorbidity is necessary to develop such interventions, as little is known about how or why this co-occurrence exists. A comprehensive model of the underlying mechanisms associated with comorbid ADHD and EDs is needed to improve understanding of the development of the comorbidity. Moreover, while there are gender differences within each disorder, literature is limited regarding to the comorbidity among males, leading to …

The Relationship Of Pre-Enrollment Timespans To Persistence And Time-To-Degree Of Transfer Students At A Four-Year, Metropolitan University, Michelle Denise Bombaugh

USF Tampa Graduate Theses and Dissertations

This research study investigated the relationship to the pre-enrollment factors of admissions-to-enrollment and orientation-to-enrollment timespans to transfer student success as measured by persistence and the length of time taken to earn a baccalaureate degree. This quantitative study analyzed secondary data (N = 357) from a large, four-year, public research institution in the southeast United States. A logistic regression analysis was used to explore the relationships between the pre-enrollment timespans and persistence. The relationship between the admissions-to-enrollment timespan and persistence was not statistically significant. The orientation-to-enrollment timespan was found to have a statistically significant relationship to persistence (p < .05). This indicated that students who had increased orientation-to-enrollment timespans were more likely to persist. To further explore this relationship, a multiple logistic regression analysis was conducted to control for possible extraneous demographic, pre-enrollment, and enrollment variables. The relationship of orientation-to-enrollment timespan and persistence continued to be statistically significant. An ordered logistic technique was used to explore the relationship between the admissions- and orientation-to-enrollment timespans and time-to-degree completion. Neither timespan was found to have a significant relationship with time elapsed to complete the degree. Implications for admissions and orientation timespans were discussed in relation to transfer student transitions.

Sleep, Depressive Symptoms And Cognition In Older Adults And Caregivers Of Persons With Dementia, Glenna Shemida Brewster

USF Tampa Graduate Theses and Dissertations

Caregivers of persons with dementia, who are often older adults, report sleep disturbance, high rates of depressive symptoms and may be at risk for impaired cognition. This dissertation examined sleep, depressive symptoms, and cognition in older adults and caregivers of persons with dementia. The aims of the review of literature were to understand, in community dwelling adults 60 years and older, the relationships among sleep parameters (sleep onset latency, wake after sleep onset, sleep efficiency, total sleep time, and general sleep complaints), and the domains of cognition (Executive Function, Attention, Episodic Memory, Working Memory, Processing Speed), and global cognition. Based …

Straight Benevolence: Preserving Heterosexual Authority And White Privilege, Robb James Bruce

USF Tampa Graduate Theses and Dissertations

This thesis analyzes three current and popular media sites, exploring a term I coin “straight benevolence.” An ostensibly supportive and progressive attitude adopted by heterosexuals and expressed toward gay men in the United States, straight benevolence surreptitiously subordinates gayness and further entrenches white masculine heterosexual privilege. In my examination of hip-hop artist Macklemore’s “Same Love,” seven Major League Baseball “It Gets Better” gay-advocacy videos, and the “Suddenly, Last Summer” episode of ABC’s primetime U.S. television series Modern Family, I take an intersectional approach to address the interanimation of sexuality, gender, and race. I ask: In what ways is gay male …

Functional Analysis Of The Ovarian Cancer Susceptibility Locus At 9p22.2 Reveals A Transcription Regulatory Network Mediated By Bnc2 In Ovarian Cells, Melissa Buckley

USF Tampa Graduate Theses and Dissertations

GWAS have identified several chromosomal loci associated with ovarian cancer risk. However, the mechanism underlying these associations remains elusive. We identify candidate functional Single Nucleotide Polymorphisms (SNPs) at the 9p22.2 ovarian cancer susceptibility locus, several of which map to transcriptional regulatory elements active in ovarian cells identified by FAIRE-seq (Formaldehyde assisted isolation of regulatory elements followed by sequencing) and ChIP-seq (Chromatin Immunoprecipitation followed by sequencing) in relevant cell types. Reporter and electrophoretic mobility shift assays (EMSA) determined the extent to which candidate SNPs had allele specific effects. Chromosome conformation capture (3C) reveals a physical association between Basonuclin 2 (BNC2) and …
