A Fall Prevention System For The Elderly And Visually Impaired, Yueng Santiago De La Hoz Isaza

USF Tampa Graduate Theses and Dissertations

The World Health Organization claims that there are more than 285 million blind and visually impaired people in the world. In the US, 25 million Americans suffer from total or partial vision loss. As a result of their impairment, they struggle with mobility problems, especially the risk of falling. According to the National Council On Aging, falls are among the primary causes for fatal injury and they are the most common cause of non-fatal trauma-related hospital admissions among older adults. Visibility, an organization that helps visually impaired people, reports that people with visual impairments are twice as likely to fall …

Signal Detection Of Adverse Drug Reaction Using The Adverse Event Reporting System: Literature Review And Novel Methods, Minh H. Pham

USF Tampa Graduate Theses and Dissertations

One of the objectives of the U.S. Food and Drug Administration is to protect the public health through post-marketing drug safety surveillance, also known as Pharmacovigilance. An inexpensive and efficient method to inspect post-marketing drug safety is to use data mining algorithms on electronic health records to discover associations between drugs and adverse events.

The purpose of this study is two-fold. First, we review the methods and algorithms proposed in the literature for identifying association drug interactions to an adverse event and discuss their advantages and drawbacks. Second, we attempt to adapt some novel methods that have been used in …

Curating Illustrations Of Lewis Carroll’S Alice’S Adventures In Wonderland, Lindsay Persohn

USF Tampa Graduate Theses and Dissertations

In the 150 years since Lewis Carroll and John Tenniel (1865/1866) first published Alice's Adventures in Wonderland, various illustrators have found inspiration in this story to recreate its images again and again. Since Carroll and Tenniel, Wonderland has concerned itself with sociocultural ideas and the work of artists who re-illustrated this story provide ways to trace history of these ideas.

Accordingly, the purpose of this project was to examine connections and breaks with tradition in illustration that contribute to an evolution of meaning in the Wonderland story. Additionally, through this project, I worked to interpret ideas from different artists in …

School Counselors' Role In Reducing Aggression In Children In Alternative Education Programs, Deirdra Sanders-Burnett

USF Tampa Graduate Theses and Dissertations

Despite efforts to reduce the occurrence of physical aggression in traditional school environments, some students persist in engaging in physical aggression and are assigned to alternative education programs as an alternative to expulsion. However, relatively little is known about the types of services that school counselors provide to help these students. This case study investigated the services that school counselors provide to the young children attending disciplinary alternative education programs in a public-school district in central Florida. The participants consist of two school counselors who provided services to the students assigned to the alternative disciplinary programs and two district-level administrators …

Strategic Negligence: Why The United States Failed To Provide Military Support To The Syrian Resistance In 2011-2014, Konrad J. Trautman

USF Tampa Graduate Theses and Dissertations

The US military’s culture, structure, and process for providing advice to the president and his national security decision-making team are flawed due to the marginalization of unconventional warfare (UW) expertise -- UW is the military’s doctrinal term for support to resistance activities and movements. This marginalization results in inadequate consideration for applying UW as a strategic option for the nation.

Through a qualitative methods case study analysis utilizing macro- and micro-level process-tracing with a conceptual framework based on Niklas Luhmann’s Systems Theory, the author shows that viable and acceptable resistance elements existed in Syria in March 2011 to June 2014 …

Remote Sensing And Spatial Metrics For Quantifying Seagrass Landscape Changes: A Study On The 2011 Indian River Lagoon Florida Seagrass Die-Off Event, René Dieter Baumstark

USF Tampa Graduate Theses and Dissertations

Florida’s seagrasses are ecologically important marine environments which have suffered major degradation caused by increasing anthropogenic pressures. A 2011 seagrass die-off event caused by an algal bloom in the Florida Indian River Lagoon (IRL) was particularly severe with a majority of seagrass lost in areas such as the Banana River. An understanding of how this coastal marine environment changed is an important step toward better managing resources for conservation. Modern tools and methods provide new opportunities to study these changes at the landscape scale, a scale that informs on the larger more comprehensive state of a system. Classified satellite imagery …

Transition Of Persons With Developmental Disabilities From Parental To Sibling Co-Residential Care: Effects On Sibling Caregiver Well-Being And Family Functioning, Richard Steven Glaesser

USF Tampa Graduate Theses and Dissertations

Comprehensive improvements in medical care, technology and residential settings have resulted in persons with developmental disabilities (DD) advancing to older age and outliving parental caregivers (Heller & Arnold, 2010). Typical siblings are expected to become the primary caregiver to their sibling with DD when parents become ill or die and unable to provide care (Burke, Fish, & Lawton, 2015; Heller & Arnold, 2010). This dissertation looks at the wellbeing and family functioning of siblings who become the co-residential caregiver following the transition of a brother or sister with DD from parental to sibling co-residential care. The family systems framework was …

Breaking The Crass Ceiling? Exploring Narratives, Performances, And Audience Reception Of Women's Stand-Up Comedy, Sarah Katherine Cooper

USF Tampa Graduate Theses and Dissertations

Despite the long history of stand-up comedy as a distinct form of popular entertainment, there has been little sociological attention given to its cultural significance. Comedians have arguably become legitimate and visible voices in many public conversations about social issues and social justice. This dissertation explores the cultural work of women’s comedy in popular culture. Specifically, I examine narrative representation and audience reception of women’s stand-up comedy through multi-method qualitative inquiry.

First, I analyze stand-up performances by popular U.S. comedians Amy Schumer, Wanda Sykes, and Margaret Cho. Through narrative analysis, I focus on the ironic performativity of Schumer and the …

The Strategic Naturalism Of Sandra Harding's Feminist Standpoint Epistemology: A Path Toward Epistemic Progress, Dahlia Guzman

USF Tampa Graduate Theses and Dissertations

This dissertation considers the “strategic naturalism” of Sandra Harding’s standpoint theory in the philosophy of science, and it should be applied to epistemology. Strategic naturalism stipulates that all elements of inquiry are historically and culturally situated, and thereby subject to critical reflection, analysis, and revision. Allegiance to naturalism is de rigueur, yet there is no clear agreement on the term’s meaning. Harding’s standpoint theory reads the lack of definition as indicative of its generative possibilities for epistemic progress. The driving question is why Harding’s approach has not been considered a viable candidate for determining progress in epistemology. Beyond the fact …

Using In-Vivo Audio Feedback To Improve Cycling Performance, Andrew Lee Coet

USF Tampa Graduate Theses and Dissertations

Many behavioral interventions have attempted to increase sports performance. These interventions include: goal setting and feedback, behavioral coaching, and acoustical guidance. The use of technological devices in all areas of life continues to steadily increase. Therefore, behavioral interventions should also adapt to meet these changes in technology. One such intervention is in-vivo audio feedback in which participants receive live feedback about their current performance while practicing the skill. In-vivo audio feedback has not yet been rigorously evaluated as a means of improving sports performance. This study used a multiple baseline across participants design to evaluate the effects of in-vivo audio …

There is a need for a low effort yet effective way to teach yoga postures to individuals who do not take private yoga classes and may practice at home. This study evaluated the effects of using a picture-based task analysis and self-evaluation on the skill acquisition of yoga postures. A multiple baseline across yoga postures was used. During the task analyses intervention, the participants received a task analysis, performed the posture, and scored the …

The Role Of Organizational Justice In Predicting Attitudes Toward Body-Worn Cameras In Police Officers, Nathaniel L. Lawshe

USF Tampa Graduate Theses and Dissertations

Body-worn cameras are a promising new development in policing. They have been linked to positive outcomes such as decreases in use of force and complaints against officers. However, this new technology has produced a number of issues that could thwart a successful body-worn camera program implementation. One issue is the extent in which officers possess positive attitudes toward using body-worn cameras. If officers do not view body-worn cameras positively, cameras may not be used to their full potential.

A promising factor that has emerged from past research in explaining attitudes toward body-worn cameras is organizational justice. Broadly, organizational justice is …

Telling A Rape Joke: Performing Humor In A Victim Help Center, Angela Mary Candela

USF Tampa Graduate Theses and Dissertations

This study examines the function of humor as a discourse in discussion of sexual battery. In this study, I examine the ways sexual battery, consent, and victimization are social constructed. Humor is a form of discourse where individuals are allowed to speak more freely about taboo topics, including that of sexual battery. I examine humor within presentations given from a Victim Help Center. Using field notes, slides, videos, and audio-recordings, I analyze instances of humor within the presentations. I analyze the data multimodally, in order to provide a richer, qualitative analysis. In this thesis, I argue that humor observed in …

Using basaltic glass samples collected from multiple dive cruises that explored Hess Deep geology, volatile and chemical data were collected at USF using FTIR and EMPA, respectively. In addition, a data suite of samples of glass from Hess Deep were compiled from the EarthChem database. The intention was to use the data suite and models to compare the Hess Deep regime to analog models for mid-ocean ridge crystallization regimes and tectonic structures. The USF and …

The Stability Of Sand Waves In A Tidally-Influenced Shipping Channel, Tampa Bay, Florida, John Willis Gray

USF Tampa Graduate Theses and Dissertations

Tidally-influenced sandwaves are common coastal features present in various settings, including shipping channels. The main shipping channel in Tampa Bay under the Bob Graham Sunshine Skyway Bridge (a.k.a. the Skyway Bridge) contains such sandwave bedforms. Between the years 2000 and 2017, these bedforms have been surveyed with multibeam echosounders (MBES) on 21 occasions with ranging coverage and quality of returns. Surveys between 2000 and 2009 used a 300 kHz Kongsberg EM3000; surveys between 2015 and 2017 used a 400 kHz Reson Seabat 7125. For comparable surveys, bathymetry, backscatter, slope, curvature, planform curvature, and profile curvature maps were created and analyzed. …

Eliminating The Uncertainty Of Hong Kong In 1990s: Tsui Hark’S Once Upon A Time In China (1, 2, 3), Zhanwen Peng

USF Tampa Graduate Theses and Dissertations

My argument is that the Wong Fei-hung film series, Once Upon a Time in China (Tsui Hark, Chapters 1, 2, 3), not only affirms the ideas of Confucianism but also criticizes them. Tsui Hark’s film series express Hong Kong’s tension of selecting eastern tradition and western modernity before it returned to mainland China in 1997, which represents the selection of entirely different values between East and West. Though the film series was made from 1991 to 1993, Hark started considering how to eliminate the uncertainty in selecting ideology after Hong Kong’s return. He provides his answer by combining eastern Confucianism …

Anticipatory Motivation For Drinking Alcohol: An In-Vivo Study, Bryan Benitez

USF Tampa Graduate Theses and Dissertations

Numerous studies from various research groups have already shown the usefulness of alcohol expectancies as predictors of long-term future alcohol consumption. The present study extends this line of research by directly testing whether alcohol expectancies measured in the moment using free association are useful as predictors of alcohol consumption in the next few hours. An ecological momentary assessment (EMA) procedure was used to examine how alcohol expectancies might fluctuate during days in which many people expect to drink (e.g. Fridays, Saturdays) and how these fluctuations in alcohol expectancies might predict future drinking and/or co-vary with important contextual variables during that …

Evaluating The Effectiveness, Feasibility, And Treatment Acceptability Of A Culturally Adapted Version Of Discriminated Functional Communication With Afro-Caribbean Families, Monique R. Litchmore

USF Tampa Graduate Theses and Dissertations

The majority of behavioral analytic interventions reflect European-American values. One useful intervention is discriminated functional communication training (DFCT), which may be implemented to increase the generalizability of functional communication training (FCT). However, the discriminative stimuli used during DFCT may not adequately reflect what is commonly used in various cultures. Thus, the purpose of the current study was to evaluate the effectiveness, feasibility (in the form of training parents to implement), and treatment acceptability of a culturally adapted version of DFCT with Afro-Caribbean families. Three children with ASD along with their mothers participated in the study. Results showed that culturally adapting …

Occupational Sharps Injuries In Medical Trainees At The University Of South Florida: A Follow-Up Study, Kourtni L. Starkey

USF Tampa Graduate Theses and Dissertations

Medical trainees (medical students and resident physicians) are at high risk of sharps injury (needlestick injury). High rates of sharps injury in this population and the risk incurred by exposure to bloodborne pathogens poses a threat both to medical trainees who are at risk for bloodborne pathogen exposure and to training institutions for legal and financial reasons. This study examines the prevalence of sharps injuries in medical trainees at the University of South Florida and compares that to data on sharps injuries in US medical trainees. Data from the present study was compared to previously collected USF medical trainee sharps …

Molecular Phylogenetics Of Floridian Boletes, Arian Farid

USF Tampa Graduate Theses and Dissertations

The boletes are macrofungi which have undergone extensive taxonomic revisions since the advent of molecular tools. To further our understanding of the boletes in peninsular Florida, we sequenced two common Floridian boletes, and analyzed them with molecular phylogenetic tools. Boletus rubricitrinus, a common Florida bolete often found in lawns under Quercus, and likely has a distribution that extends to Texas. Based on ITS and LSU sequences and morphological studies, this species belongs in the genus Pulchroboletus. As the holotype is in poor condition, an epitype is established here. A thorough description of macroscopic and microscopic features is also provided for …

An alternating treatments design with an additional baseline phase was used across three teacher recommended students. During baseline, the teacher conducted a group language arts routine as normal, posing questions to the class and prompting them to raise their hands to answer. During the intervention phase, preprinted response cards (two sets: one true/false and one A/B) were passed out to the class to utilize during …

Improving The Security Of Building Automation Systems Through An Sel4-Based Communication Framework, Richard Habeeb

USF Tampa Graduate Theses and Dissertations

Existing Building Automation Systems (BASs) and Building Automation Networks (BANs) have been shown to have serious cybersecurity problems. Due to the safety-critical and interconnected nature of building subsystems, local and network access control needs to be finer grained, taking into consideration the varying criticality of applications running on heterogeneous devices. In this paper, we present a secure communication framework for BASs that 1) enforces rich access control policy for operating system services and objects, leveraging a microkernel-based architecture; 2) supports fine-grained network access control on a per-process basis; 3) unifies the security control of inter-device and intra-device communication using proxy …

Using Video Self-Evaluation To Enhance Performance Of Competitive Dancers, Jesenia Giambrone

USF Tampa Graduate Theses and Dissertations

This study used a multiple baseline across behaviors design to evaluate the use of video self-evaluation on the performance of dance movements. The self-evaluation condition included training participants how to view a video of them performing the dance movement and evaluate their own performance from video using a task analysis of the movement. Each participant applied the self-evaluation procedure to three separate dance moves. Target behaviors were scored using an individualized task analysis for each dance move. Self-evaluation improved all three dance moves for each participant. Self-evaluation produced an increase in all target behaviors from baseline to intervention for each …

Using Video Feedback To Increase Figure Skaters' Performance, Lori Greenberg

USF Tampa Graduate Theses and Dissertations

Figure skating is a competitive sport that requires intensive training which can be taught in a variety of settings. There are various methods to teaching figure skaters new skills such as positive and corrective feedback, modeling and coaching procedures, and physical guidance. These different approaches may lead to a lack of consistency among coaches. Over the years, these established coaching strategies have not changed substantially as training methods are passed down from coach to student. Also, research in the area of what constitutes effective coaching methods is lacking. Skaters may progress more quickly in skill development if coaches are implementing …

Impact Of Substrate To Inoculum Ratio On Methane Production In High Solids Anaerobic Digestion (Hs-Ad) Of Food Waste, Yard Waste, And Biosolids, Phillip James Dixon

USF Tampa Graduate Theses and Dissertations

High solids anaerobic digestion (HS-AD) is an alternative for managing the organic fraction of municipal solids waste (MSW), which produces mainly methane (CH4) and fertilizer as byproducts. HS-AD offers a potentially more economically and environmentally sustainable option compared with landfilling or incineration waste-to-energy facilities. However, HS-AD is a complex process requiring specific microbial communities working together symbiotically. Previous studies have found that the substrate to inoculum (S/I) ratio affects CH4 production and yield in HS-AD reactors by affecting substrate mass and energy transfer as well as microbial activity. In this thesis, biochemical methane potential (BMP) assays were used to investigate …

A Queer And Crip Grotesque: Katherine Dunn's, Megan Wiedeman

USF Tampa Graduate Theses and Dissertations

The grotesque has long been utilized in literature as a means for subverting societal constraints and inverting constructions of normalcy. Unfortunately, in many instances, it has been constructed at the expense of disabled characters using their embodiment as metaphorical plot devices rather than social and political agents. Criticism of the grotesque’s use of bodily difference has prompted this analytical project in order to rethink disability as socially and politically positioned within texts, rather than simply aesthetics for symbolic means. The aim of this paper is to explore the ways the literary grotesque can be reread using queer theory and crip …

Better Safe Than Sorry: The Relationship Between Locus Of Control, Perception Of Risk, And Cyber Misbehaviors, Kim Johnson

USF Tampa Graduate Theses and Dissertations

Information security is of vital importance to organizations. Breaches in security very often stem from behaviors of the system operator. Cyber misbehaviors on the part of employees can have devastating repercussions on the well-being of an organization. Up to now, research has mainly focused on how to protect information systems from outside attack, and only recently have researchers turned to the part the operator plays in keeping the systems safe. The present study investigated some individual differences that may play a role in people’s cyber behavior. The purpose of the study was to determine if locus of control was related …
