Self-Protection In Cyberspace: Assessing The Processual Relationship Between Thoughtfully Reflective Decision Making, Protection Motivation Theory, Cyber Hygiene, And Victimization, C. Jordan Howell

USF Tampa Graduate Theses and Dissertations

The current study, using structural equation modeling, assesses the processual relationship between thoughtfully reflective decision making (TRDM), theoretical constructs derived from protection motivation theory (PMT), cyber hygiene, and online victimization to determine the cognitive decision-making process that leads to the adoption of online self-protective behaviors, which reduces the occurrence of victimization experiences. Findings, derived from a general sample of Internet users in the United States, reveal: (1) engagement in cyber hygiene practices, as a form of target hardening, decreases Internet users’ experiences with online victimization; (2) thoughtfully reflective decision makers, in the face of cyber threats, develop higher threat appraisals …

Arab Undergraduate Students' Perceptions Of Their Transition To Learn Mathematics In English In The United States, Annetta Hastings

USF Tampa Graduate Theses and Dissertations

The number of students who choose to pursue higher education outside their home country has continued to grow, and one of the most popular international destinations is the United States. International students, whose home language is not English, can find this educational opportunity to be academically challenging. Institutions of higher learning can admit international students and expect them to adjust to the linguistic, cultural, and social differences in a new educational system without appropriate support. To better support international students in undergraduate mathematics, researchers have focused on how language and culture affect mathematical understanding (Barton & Neville-Barton, 2003; Durand-Guerrier et …

Evaluating The Use Of An Interdependent Group Contingency In Online Graduate Courses To Increase Engagement, Tiana Evans

USF Tampa Graduate Theses and Dissertations

Enrollment in online academic programs has increased substantially in recent years (Allen & Seaman, 2011) and is especially relevant due to the COVID-19 pandemic (Khalil et al., 2020). Peer interaction and engagement opportunities are strategies associated with course satisfaction, test performance, and grades and should be incorporated into online courses (Conaway et al. 2005). Group contingencies have been commonly studied in face-to-face classrooms and have been found to be effective intervention in changing target behavior in elementary and secondary education settings (Barrish et al., 1969; Deshais et al., 2019; Harris & Sherman, 1973; Mitchell et al. 2015; Wiskow et al., …

Investigating The Novel Role Of Dextromethorphan In Mitigating Oxidative Stress Induced Changes In Retinal Pigment Epithelial Cells (Rpe), Zeinab A. Mohamed

USF Tampa Graduate Theses and Dissertations

Oxidative stress contributes to the degeneration of retinal pigment epithelial (RPE) cells and photoreceptors that lead to the dry form of age-related macular degeneration. Activation of N-Methyl-D-aspartate (NMDA) receptors contributes to the increase of free radicals that induce oxidative stress-induced changes. Our study investigates if Dextromethorphan, an NMDA receptor antagonist, reverses oxidative stress-induced changes in RPE. We used Paraquat and H2O2 as oxidative stress-inducing agents to induce oxidative damage in human ARPE-19 cells. To illustrate the change in cell viability and measure the apoptosis of ARPE-19 cells from oxidative damage, we performed MTT assay and Annexin V-DAPI flow cytometry analysis. …

Moving Science To Practice: Exploring Implementation Practice Capacity In Community Settings, Enya B. Vroom

USF Tampa Graduate Theses and Dissertations

Due to the significant prevalence of mental and substance use disorders in the United States, the push for the development and implementation of evidence-based practices (EBPs) has grown exponentially in the last 30 years. Community-based organizations (CBOs) (i.e., self-governing and/or not-for profit) have been identified as significant providers of behavioral health services. However, there are gaps in the literature surrounding CBO implementation capacity, meaning their ability to adopt, implement, and sustain EBPs. There is a need for more research examining capacity training initiatives that specifically target CBOs and implementation practice. The purpose of this dissertation research was to investigate how …

Efficient Hardware Constructions For Error Detection Of Post-Quantum Cryptographic Schemes, Alvaro Cintas Canto

USF Tampa Graduate Theses and Dissertations

Quantum computers are presumed to be able to break nearly all public-key encryption algorithms used today. The National Institute of Standards and Technology (NIST) started the process of soliciting and standardizing one or more quantum computer resistant public-key cryptographic algorithms in late 2017. It is estimated that the current and last phase of the standardization process will last till 2022-2024. Among those candidates, code-based and multivariate-based cryptography are a promising solution for thwarting attacks based on quantum computers. Nevertheless, although code-based and multivariate-based cryptography, e.g., McEliece, Niederreiter, and Luov cryptosystems, have good error correction capabilities, research has shown their hardware …

Behavior Analytic Interventions For Promoting Skill Acquisition In Individuals With Asd: Two Case Studies, Taylor Marie Comber

USF Tampa Graduate Theses and Dissertations

This report describes two case studies that used behavior analytic interventions to promote skill acquisition during structured instructional activities for individuals with autism spectrum disorder (ASD). The first study examined the effects of presession pairing (PSP) implemented by a teacher in the natural classroom setting for a 6-year-old with ASD whose problem behavior was associated with gaining access to attention and escaping from task demands. Results showed PSP augmented with a visual cue resulted in increased on-task behavior and decreased disruptive behavior. The second study examined the use of discrete trial training (DTT) for a 16-year-old female adolescent with ASD …

Longitudinal Trajectory Tracking Analysis For Autonomous Electric Vehicles Based On Pid Control, Hossein Amiri

USF Tampa Graduate Theses and Dissertations

The implementation of autonomous vehicles has huge potential for revolutionizing transportation as we currently know it. All use cases of autonomous vehicles require the vehicle to travel on a pre-specified path. Accurate tracking of this defined trajectory is a crucial aspect of the implementation of autonomous vehicles; a controller system is required to translate this pre- defined trajectory in the form of the throttle, brake, and steering inputs. This project covers the application of a Proportional-Integral-Derivative (PID) controller to achieve longitudinal trajectory tracking of autonomous electric vehicles with stability and accuracy in the CARLA autonomous driving simulation platform. The implemented …

Consumerism And Pride: The Fate Of Paris’ Marais “Gayborhood”, Christina M. Csensich

USF Tampa Graduate Theses and Dissertations

In the 1980s the Marais neighborhood in Paris, France, became a haven for queer people, specifically gay, white men, filled with queer-owned and queer-centric businesses. By the year 2020, however, these businesses had been priced out by name-brand international corporations. In the 1990s, French television commercials and programs would not speak the word ‘homosexual,’ even when a character was openly queer. By the 2010s, companies regularly featured queer people and gay pride imagery and slogans in their advertising. The queer community in Paris has a unique relationship with the consumer economy, one that ties aspects of queer identity directly to …

The Influence Of Maternal Body-Shaming Comments And Bodily Shame On Portion Size, Savannah R. Flak

USF Tampa Graduate Theses and Dissertations

Young adult women are more likely to be dissatisfied with their bodies (Wansink et al., 2017) and engage in disordered eating patterns when they have a history of receiving parental comments about their bodies during childhood (Fortesa & Ajete, 2014). Furthermore, high bodily shame mediates the relationship between receiving critical messages about eating from parents during childhood and disordered eating behaviors for young adult women (Oliveira et al., 2019). Altogether, this suggests that bodily shame is a distinct pathway linking parental influence during adolescence to eating disturbances. However, little research has examined the unique roles that bodily shame, internalized weight …

Prediction Of The Effects Of Turbulence On Vehicle Hydroplaning Using A Numerical Model, Thathsarani Dilini Herath Herath Mudiyanselage

USF Tampa Graduate Theses and Dissertations

Pneumatic hydroplaning has been identified as one of the major causes of wet weathertraffic accidents. Therefore, knowledge of potential hydroplaning speeds is crucial in designing roadways to reduce crash risks. It has been shown that the tire inflation pressure is the predominant factor affecting the hydroplaning speed while factors such as the water film thickness also contribute heavily to this phenomenon. Extensive research has been directed at the development of accurate models to predict the effects of vehicle characteristics, pavement conditions and water film thickness on hydroplaning. Current literature does not indicate any studies directed at understanding the effects of …

The Mass Is The Medium: Marshall Mcluhan And Roman Catholic Liturgical Change, Ashil D. Manohar

USF Tampa Graduate Theses and Dissertations

The liturgical changes of Vatican II sought to bring a period of renewal to the Catholic laity by encouraging active participation and making the Mass more simple to understand. However, the time after the Council was characterized by confusion and disengagement by the laity. I will be discussing three significant changes to the liturgy at this time, The change from Latin to the vernacular, the change in the orientation of the altar and priest, and the change in acoustics, sound, and music. I will be examining all of these changes through the media theory of Marshall McLuhan, famous for coining …

Bait-And-Kill: Targeting A Novel Heme Biochemical Pathway In Hundreds Of Cancers, Christopher G. Marinescu

USF Tampa Graduate Theses and Dissertations

Cancer cells are characterized by their ability to grow and proliferate in rates that far exceed normal cells by modifying their iron/heme metabolisms to levels higher than normal. This imbalance of heme biosynthesis can lead to cancer cells having a flux of heme intermediates to the point where they enter a state called heme-overdrive. Heme-overdrive is a process unique to a variety of cancers but absent in normal tissues. With this enhanced production, heme can act as an epigenic regulator for signaling proliferation (18). Through the novel strategy called ‘bait-and-kill,’ cancer cells will be coerced into a state of heme …

Defining Codes Based On The Consolidated Framework For Implementation Research In The Context Of The Implementing Universal Lynch Syndrome Screening, Jasmine A. Burton-Akright

USF Tampa Graduate Theses and Dissertations

Lynch syndrome (LS) is the most common hereditary cause of both colorectal cancer (CRC) and endometrial cancer (EC). Universal tumor screening (UTS) of newly diagnosed EC and CRC patients has been shown to be both an effective and economical approach to identify patients with LS and subsequently reduce future cancer s for patients and their family members. Despite its efficacy, LS UTS has not been consistently adopted across hospital systems and existing programs vary widely in their structure and execution. The Implementing Universal Lynch Syndrome Screening (IMPULSS) study aims to determine the critical factors necessary for successful implementation of LS …

Empress Nur Jahan And Female Empowerment: A Critical Analysis Of A Long-Forgotten Mughal Portrait, Angela N. Finkbeiner

USF Tampa Graduate Theses and Dissertations

This thesis is a study of a seventeenth-century watercolor portrait of the Mughal EmpressNur Jahan (r. 1611-1627). Titled Nur Jahan Holding a Musket and created by court painter Abu’l Hasan, the painting has not been the subject of a scholarly work before. In this unorthodox depiction of a female, Nur Jahan is shown sporting androgynous attire while actively loading a matchlock musket. Through visual and textual analysis, I read this portrait as a symbol of an empowered female and argue that once its meaning is decoded it can serve as a complex historical document that complicates Nur Jahan’s persona. Moving …

Novel Educational Material For Patients With A Variant Of Uncertain Significance (Vus) In A Cancer Risk Gene, Meghan E. Kelley

USF Tampa Graduate Theses and Dissertations

The number of individuals being tested for hereditary cancer syndromes has greatly increased in the last several years and many people receive Variants of Uncertain Significance (VUS) as a test result. Although VUS results should not guide medical management, patients and even some healthcare providers continue to use a VUS to alter or receive unnecessary medical care.

We conducted a needs assessment via literature review and analyzed VUS patient interviews from a previous study with the goal of identifying various themes that could help determine content, layout, and messaging to incorporate into online educational materials. The needs assessment found few …

“Just Joking”: Women’S Cardiovascular Responses To Sexist Humor, Samantha Shepard

USF Tampa Graduate Theses and Dissertations

The ambiguity inherent to humorous communication may make women minimize experiences of sexist jokes, which may have downstream emotional and motivational consequences. The present thesis study tested whether the manner in which sexism is communicated, as a statement or joke, would reflect the motivational intensity model in cardiovascular responses during a performance-based task. Additionally, the present studies tested whether blatant and humorous sexism differentially affects emotional responses, evaluations of a male speaker, reporting of sexist misconduct, and ingroup identification. Using an online chat paradigm, participants were randomly assigned to receive one of three messages: a sexist joke, blatantly sexist statement, …

"Duck Wars": Examining The Narrative Construction Of A "Problem" Species, Jenna A. Bateman

USF Tampa Graduate Theses and Dissertations

The problematization of non-human animals occurs through a process of claimsmaking that constructs certain species as “problems”. My thesis examines the news narrative constructions of the Muscovy duck in Florida and Texas. I use a narrative analysis to examine the themes through which news narratives make claims in their construction of the “duck wars” in Florida and Texas. In the “duck wars”, the problematization of the Muscovy occurs through a set of claims made about the species by the reporters and residents in Florida and Texas neighborhoods. There are also sets of claims about other groups associated with the species, …

Strategies In Botnet Detection And Privacy Preserving Machine Learning, Di Zhuang

USF Tampa Graduate Theses and Dissertations

Peer-to-peer (P2P) botnets have become one of the major threats in network security for serving as the infrastructure that responsible for various of cyber-crimes. Though a few existing work claimed to detect traditional botnets effectively, the problem of detecting P2P botnets involves more challenges. In this dissertation, we present two P2P botnet detection systems, PeerHunter and Enhanced PeerHunter. PeerHunter starts from a P2P hosts detection component. Then, it uses mutual contacts as the main feature to cluster bots into communities. Finally, it uses community behavior analysis to detect potential botnet communities and further identify bot candidates. Enhanced PeerHunter is an …

An Evaluation Of Video Modeling And Video Modeling With Video Feedback To Enhance The Performance Of Competitive Soccer Goalkeepers, Alexandra Martina Capalbo

USF Tampa Graduate Theses and Dissertations

Several studies have evaluated the effects of consequent and antecedent procedures on athletic performance, including video modeling plus video feedback (VM+VF) as a treatment package. Although the effects of the VF consequent component have been well researched, relatively scant literature exists assessing the effectiveness of the VM component as an antecedent strategy. Additionally, these interventions have not been studied to improve goalkeeping skills of soccer players. Therefore, this study used a multiple baseline across behaviors to compare the effects of VM to the VM+VF to train goalkeeper skills to soccer players. Task analyses were established for three goal keeping skills …

Recognizing Emotion In The Wild Using Multimodal Data, Shivam Srivastava

USF Tampa Graduate Theses and Dissertations

In this work, I will present our approach of using multi-modal data for recognizing human emotion and behavior in the wild. The study is divided into four tasks: group emotion recognition, driver gaze prediction, student engagement prediction, and emotion recognition using physiological signals. We explore multiple approaches including classical machine learning tools such as random forests, state-of-the-art deep neural networks, and multiple fusion and ensemble-based approaches. We also show that similar approaches can be used across tracks as many of the features generalize well to the different problems (e.g. facial features).

Evaluating The Use Of Behavioral Skills Training To Teach Substitute Caregivers To Identify Hazards, Carlos Abarca

USF Tampa Graduate Theses and Dissertations

The leading cause of death for children across the world is unintentional injuries (UNICEF 2001). Hazards such as accessible pools, poisons, and small ingestible items are the leading causes of unintentional injuries. Behavioral interventions such as Project 12-Ways/Safe Care have been used to teach parents how to be proactive in structuring a home free of accessible hazards by teaching the parents to identify and remove hazards in their home. Though the Project 12-Ways/Safe Care model has over 30 years of literature supporting its efficacy, the model has not been tested with substitute caregivers who often play a critical role in …
