The Effects Of Repetitive Thought And Construal Level On Alcohol Consumption, Andrew Mark Kiselica

USF Tampa Graduate Theses and Dissertations

Repetitive thought, or the recurrent, often cyclical, focus on self-relevant concerns and experiences, is one liability that may be common across internalizing (INT) and externalizing (EXT) disorders. One particular area of interest for examining repetitive thought as a transdiagnostic process is in relation to alcohol use because alcohol abuse and dependence are the most common, and possibly most costly, EXT disorders. This study experimentally induced abstract repetitive thought, concrete repetitive thought, or distraction to test if repetitive thought and construal level have an effect on drinking behavior. It was hypothesized that individuals in both repetitive thought conditions would drink more …

Visual Slam And Surface Reconstruction For Abdominal Minimally Invasive Surgery, Bingxiong Lin

USF Tampa Graduate Theses and Dissertations

Depth information of tissue surfaces and laparoscope poses are crucial for accurate surgical guidance and navigation in Computer Assisted Surgeries (CAS). Intra-operative Three Dimensional (3D) reconstruction and laparoscope localization are therefore two fundamental tasks in CAS. This dissertation focuses on the abdominal Minimally Invasive Surgeries (MIS) and presents laparoscopic-video-based methods for these two tasks.

Different kinds of methods have been presented to recover 3D surface structures of surgical scenes in MIS. Those methods are mainly based on laser, structured light, time-of-flight cameras, and video cameras. Among them, laparoscopic-video-based surface reconstruction techniques have many significant advantages. Specifically, they are non-invasive, provide …

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 …

Improvements On Scientific System Analysis, Vladimir Grupchev

USF Tampa Graduate Theses and Dissertations

Thanks to the advancement of the modern computer simulation systems, many scientific applications generate, and require manipulation of large volumes of data. Scientific exploration substantially relies on effective and accurate data analysis. The shear size of the generated data, however, imposes big challenges in the process of analyzing the system. In this dissertation we propose novel techniques as well as using some known designs in a novel way in order to improve scientific data analysis.

We develop an efficient method to compute an analytical query called spatial distance histogram (SDH). Special heuristics are exploited to process SDH efficiently and accurately. …

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 …

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 Novel Update To Dynamic Q Algorithm And A Frequency-Fold Analysis For Aloha-Based Rfid Anti-Collision Protocols, Nikita Khanna

USF Tampa Graduate Theses and Dissertations

Radio frequency identification (RFID) systems are increasingly used for a wide range of applications from supply chain management to mobile payment systems. In a typical RFID system, there is a reader/interrogator and multiple tags/transponders, which can communicate with the reader. If more than one tag tries to communicate with the reader at the same time, a collision occurs resulting in failed communications, which becomes a significantly more important challenge as the number of tags in the environment increases. Collision reduction has been studied extensively in the literature with a variety of algorithm designs specifically tailored for low-power RFID systems.

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 …

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 …

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 …

Self-Assembly Kinetics Of Microscale Components: A Parametric Evaluation, Jose Miguel Carballo

USF Tampa Graduate Theses and Dissertations

The goal of the present work is to develop, and evaluate a parametric model of a basic microscale Self-Assembly (SA) interaction that provides scaling predictions of process rates as a function of key process variables. At the microscale, assembly by “grasp and release” is generally challenging. Recent research efforts have proposed adapting nanoscale self-assembly (SA) processes to the microscale. SA offers the potential for reduced equipment cost and increased throughput by harnessing attractive forces (most commonly, capillary) to spontaneously assemble components. However, there are challenges for implementing microscale SA as a commercial process. The existing lack of design tools prevents …

Crisis Communication And Celebrity Scandal: An Experiment On Response Strategies, Leah Champion

USF Tampa Graduate Theses and Dissertations

Recent allegations surrounding Bill Cosby presented an opportunity to combine, test, and extend situational crisis communication theory typology and image repair theory response strategies for celebrity use. Because Cosby did not respond to the numerous allegations against him, it presented an opportunity to experiment with new and existing typologies using a real case, as opposed to analyzing past response attempts or using a hypothetical case. This study used a 2 X 4 factorial design to test veracity of claims, a proposed concept, and response strategies via survey. Even though none of the hypotheses were supported, the present study opened up …

Script Training: The Role Of Written Cues, Hallie Cohen

USF Tampa Graduate Theses and Dissertations

Script training is a technique that allows persons with acquired speech and language disorders, such as nonfluent aphasia, to have islands of fluent speech during which they can speak about a topic without pausing or having word-finding errors. Scripts relevant to specific functional situations are written and practiced until memorized. Script training delivered verbally has been effective with clients with aphasia but the role of written cues in the training has not been explored. Therefore the purpose of this study was to compare the effectiveness of script training taught verbally, or verbally with a written script, in persons with aphasia. …

High-Throughput Screening Of Age-Related Changes In Caenorhabditis Elegans, Neil Copes

USF Tampa Graduate Theses and Dissertations

This project was developed to identify novel methods for high-throughput culturing and screening of C. elegans to investigate age-related metabolic changes and to survey the proteomic and metabolomic factors associated with age-related changes. To accomplish these goals we developed a novel way to grow C. elegans in liquid culture in 96-well microplates for several weeks without suffering significant fluid loss due to evaporation and without needing to shake or unseal the plates for aeration. We also developed methods for assaying the total volume of live C. elegans in microplate cultures using a fluorescence microplate reader and for performing RNAi experiments …
