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 …

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 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 …

Performing "Hurt" : Aging, Disability, And Popular Music As Mediated Product And Lived-Experience In Johnny Cash's Final Recordings, Adam Davidson

USF Tampa Graduate Theses and Dissertations

Sitting at a rarely examined intersection between aging, disability, and popular culture, this project explores how the aging body becomes the disabled body in the context of popular music. In what follows, I trouble the distinction between bodies and mediation, between lived-experience and cultural product, and I argue that the voice of the aging artist engages with his lived-experience even as he performs socially-constructed conceptions of aging and disability.

I read Johnny Cash’s 2002 cover of Trent Reznor’s “Hurt” on American IV: The Man Comes Around as a performance of the singer’s age and disabled condition. Through pain- saturated lyrics, …

Analysis Of User Interfaces In The Sharing Economy, Taylor B. Johnson

USF Tampa Graduate Theses and Dissertations

This thesis considers claims of discrimination and the interfaces that six platforms use as companies in the sharing economy.

In 2015, Benjamin Edelman, Michael Luca, and an Svirsky did an experiment with Airbnb to test the discrimination of names that sounded distinctly African American. Before and after their findings, there were members of the community who claimed that they had been discriminated against, some suing the company for not upholding their anti-discrimination policy. This leads to the question of how is one able to discriminate against someone whom they have never met and lives thousands of miles away? What information …

The Revival Western And, Kevin Thomas Mckenna

USF Tampa Graduate Theses and Dissertations

I create a dialogue between films credited with reviving the Western film genre in the early 1990’s. I examine spatial representations in a group of films I label “the revival westerns”: Kevin Costner’s Dances with Wolves (1990), Clint Eastwood’s Unforgiven (1992), and George P. Cosmatos’ Tombstone (1993). Through the use of extreme long shots, characters demonstrating a confined sense of place, and continuity editing, the revival westerns erect a concentrically scaled conception of space and place and maintain a linear temporality. However, I offer Jim Jarmusch’s Dead Man (1995) as an intervention that reassembles these spatial and temporal notions. Dead …

Cultural Adaptation And Maintenance: Chinese International Students' Use Of Facebook And Wechat, Mengni Wang

USF Tampa Graduate Theses and Dissertations

In terms of Uses and gratification theory, this study examined the relationships between the usage of social networking sites and acculturation among Chinese students who are studying in U.S. colleges (N=246). By comparing two different SNSs, American SNS (Facebook) and ethnic SNS (WeChat), it was discovered that Chinese students exposed differential needs and gratification achievement in these two SNSs. This study applied a quantitative method, and data were collected with an online survey platform "Qualtrics," which was carried out on February 2018. The present study found that the degree of Facebook gratification can lead to the increasing of use intensity. …

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 …

Classroom Support And Students’ Subjective Well-Being: A Mixed-Methods Investigation, Emily J. Wingate

USF Tampa Graduate Theses and Dissertations

In line with the positive psychology movement and the dual factor model of mental health, professionals are increasingly compelled to consider not only mechanisms through which mental distress can be alleviated, but also pathways through which students’ wellness can be fostered. While research in this area has primarily focused on positive indicators of adults’ and adolescents’ mental health, there is a need to address those factors that contribute to the wellness of elementary-aged youth. Participants in the current study included 179 fourth and fifth grade students from an elementary school located in a southeastern state. For this secondary analysis, a …

Social media enable celebrity to interact with their followers and enable followers to build the relationship through the interaction. Former research has found that openness and perceived interactivity are antecedents for parasocial interaction. In order to investigate the way to increase user’s engagement in celebrity’s social media page, this research examines the relationship between celebrity’s posts employ openness and perceived interactivity, other user’s posts employ openness and perceived interactivity, parasocial interaction, parasocial relationship, and social media engagement. Survey data were collected from 595 followers of one Chinese celebrity through an online survey. The results indicate that neither celebrity’s nor other …

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 …

Capacity Building, Environmental Justice, And Brownfield Redevelopment: A Case Study Of Harvest Hope Park, Tampa Bay, Fl, Gabrielle R. Lehigh

USF Tampa Graduate Theses and Dissertations

Harvest Hope Park is a brownfield redevelopment project for the University Area Community Development Corporation (University Area CDC), a nonprofit organization dedicated to the sustainable redevelopment of north Tampa neighborhoods. While the project is still in progress, the University Area CDC has noted a lack of community engagement by local residents. The neighborhood, sometimes referred to as “suitcase city” because of the presumed transient nature of the population, has been plagued with poverty, blight, decay, high crime rates, and a lack of basic resources for decades (32 percent of the population in this area lives below the 2016 national poverty …

Field Testing Of Affordable Well Head Protection For Locally Manufactured, Self-Supply Pitcher Pumps On Manually Driven Tubewells In Madagascar, Michal Usowicz

USF Tampa Graduate Theses and Dissertations

Lack of water access is an issue of global importance. The WHO and UNICEF’s Joint Monitoring Program estimated that in 2015 71% of the world’s population used a safely managed drinking water source and 89% of the world’s population used an improved water source within a 30-minute round trip of home. Madagascar’s national statistics lags far behind these global statistics with 54% of the population using improved water sources, 31% using unimproved water sources, and 16% with no service at all.

This research studied water access in Madagascar with self-supply Pitcher Pumps attached on hand-driven tubewells. The term self-supply in …

Teacher-Implemented Presession Pairing To Improve Classroom Behaviors In Public Schools, Rachel M. Sofarelli

USF Tampa Graduate Theses and Dissertations

Presession pairing is an antecedent intervention that has shown to decrease problem behavior of elementary school children with autism, whose problem behavior is maintained by social reinforcement. It has also shown modest increases in academic responding. However, the research on presession pairing has not examined its efficacy or acceptability in the natural classroom setting when implemented by the teacher. Therefore, this study used teacher training and a multiple baseline across participants design to test the potential efficacy of teacher-implemented presession pairing in increasing on-task behavior and reducing problem behavior of four students with problem behavior in inclusive public elementary school …

Embedded System Design Of Low-Power Wearable Bioelectronic Devices, Matthew S. Hopper

USF Tampa Graduate Theses and Dissertations

The miniaturization of electronics in modern times has enabled the possibility of creating a “continuity of care” using small wearable bioelectronic devices. Using wearable devices, such as the Fitbit or Garmin fitness trackers, allows for the exchange of data between devices which can be used to improve the accuracy of data analysis and thus patient health.

In this thesis work, three wearable bioelectronic devices are proposed: an EOG-based eye-gaze tracking assistive technology device for the physically disabled to control a computer cursor, a battery-operated miniaturized polysomnograph that can store and transmit data wirelessly to sleep technicians and a trauma-detecting personal …

Incorporating Auditory And Visual Feedback And Student Choice Into An Interdependent Group Contingency To Improve On-Task Behavior, Beth Giguere

USF Tampa Graduate Theses and Dissertations

Group contingencies are efficient and effective behavioral interventions that allow teachers to apply a reinforcement criterion to a large group of students. However, most research on group contingencies has not examined the impact of types of teacher feedback and student choice of teacher feedback incorporated into the use of group contingencies. The current study used a multiple baseline across participants design with an embedded alternating treatments design to explore the use of an interdependent group contingency that compared the effectiveness of incorporating auditory or visual feedback to improve student on-task behavior of three students in public elementary school classrooms. The …

Food Insecurity And Age Of Menarche: Using A Biocultural Approach And Life History Theory To Assess Risks Of Food Insecurity Among Girls In Tampa Bay, Fl, Mecca Burris

USF Tampa Graduate Theses and Dissertations

Using life-history theory within a biocultural perspective, this research explores whether household food insecurity correlates with early or delayed menarche among adolescent females in Tampa Bay, Florida. Early onset of puberty and menstruation is connected with numerous health consequences including growth stunting, obesity, type-2 diabetes, adult-onset asthma, reproductive cancers, increased risk for depression, behavioral problems, and early sexual activity which increases the risk for STIs and ovarian cancer. Early menarche also seems to disproportionally impact disadvantaged and minority groups. While there are many known factors that influence age at menarche (e.g.: genetics, diet), little is understood regarding the effect of …

Grooming Behaviors Of, Lauren N. Williams

USF Tampa Graduate Theses and Dissertations

The giant freshwater shrimp, Macrobrachium rosenbergii is a large species of prawn grown extensively in aquaculture settings. A social hierarchy exists within the males of this species, representing three distinct male morphotypes. These male morphotypes differ in their behavior, physiology, and morphology and include the largest blue-clawed males (BC males), moderately- sized orange-clawed males (OC males), and the undifferentiated small-clawed males (SM males). All individuals of this species perform grooming behaviors to rid themselves of body fouling which can impede important functions such as movement, respiration, chemoreception, and reproduction. Grooming behaviors in crustaceans often utilize specialized structures called setae, which …

Failing To Move Forward: Journalism, Media, And Affect In David Fincher's, Nicholas Orlando

USF Tampa Graduate Theses and Dissertations

Zodiac (David Fincher, 2007) offers a critique of the mass media’s efforts to restore American valiance with heroic narratives of ordinary people in the aftermath of 9/11. Amending prior scholarly readings of Zodiac as a serial killer narrative, I reconfigure my analysis by taking Fincher at his word and treating it as a journalism film. Borrowing a term from political theorist Elisabeth Anker, I argue that, unlike other contemporary journalism films, Zodiac is constructed as a “melodrama of failure” that, rather than seeking mastery, unveils the instability of evidence and the obsessive uncertainty of procedure.

With his film sitting between …

Combining Thermo-Plasmonics With Microfluidics For Biological Applications, Sharad Ambardar

USF Tampa Graduate Theses and Dissertations

In this project we, for the first time, integrated microfluidics with thermo-plasmonics. While microfluidics is a popular platform allowing experiments with small volumes of fluid, thermo-plasmonics can be used for powerful particle manipulation including capturing, mixing, filtering and projection. Combined, these two techniques give us an opportunity to work with numerous complex fluids containing particles, cells, and micro-beads. Here we designed, developed and tested several devices demonstrating various aspects of this exciting hybrid technology. This required use of soft lithography, metal deposition, 3D printing, oxygen plasma treatment and several other surface modification techniques. Additional challenges were in the fabrication of …

Parallelizing Tabu Search Based Optimization Algorithm On Gpus, Vinaya Malleypally

USF Tampa Graduate Theses and Dissertations

There are many combinatorial optimization problems such as traveling salesman problem, quadratic-assignment problem, flow shop scheduling, that are computationally intractable. Tabu search based simulated annealing is a stochastic search algorithm that is widely used to solve combinatorial optimization problems. Due to excessive run time, there is a strong demand for a parallel version that can be applied to any problem with minimal modifications. Existing advanced and/or parallel versions of tabu search algorithms are specific to the problem at hand. This leads to a drawback of optimization only for that particular problem. In this work, we propose a parallel version of …
