Teaching Behavioral Contingencies To Young Children With Asd Using Contingency Mapping, Marqueline Cenatus

USF Tampa Graduate Theses and Dissertations

Children with autism spectrum disorder (ASD) often exhibit problem behavior in schools, which negatively impacts their educational outcomes. Unfortunately, teachers continue to have difficulty addressing problem behavior in the classroom. Contingency mapping is a visual representation of the contingencies for engaging in a desired and undesired behaviors, which has been found to improve student behavior in the classroom setting. The current study examined the use of the contingency mapping intervention for young children with ASD. Specifically, the study examined the extent to which the contingency mapping intervention result in a decrease of off-task behavior during natural classroom activities. Three young …

Development And Evaluation Of Interactive Computerized Training To Teach Practitioners To Implement Safety Skills Training, Rasha R. Baruni

USF Tampa Graduate Theses and Dissertations

Children can experience unintentional injuries due to safety threats found in their environments (Centers for Disease Control and Prevention, 2008). Researchers have shown that children can be taught safety responses using behavioral skills training (BST) and in situ training (IST). Within the safety skills literature, there is evidence that manualized interventions are effective for teaching parents and teachers to deliver BST (Gross et al., 2007; Novotny et al., 2020). An approach that has not been evaluated for teaching safety skills is interactive computerized training (ICT). The ICT approach employs technology to deliver trainings in the absence of a trainer (Gerencser …

V2v And V2i Based Safety And Platooning Algorithms For Connected And Autonomous Vehicles, Omkar Dokur

USF Tampa Graduate Theses and Dissertations

Connected Vehicles (CVs) make transportation safe by communicating with vehicles and the infrastructure in their neighborhood. CVs are embedded with onboard units (OBUs) which transmit basic safety messages (BSMs) containing the location, heading, and velocity information of the vehicle using either Dedicated Short-Range Communications (DSRC) or Cellular Vehicle-to-Everything (C-V2X) technology. These BSMs can be used to warn drivers using various vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) applications. Along with these applications, CV technology also gives rise to cooperative vehicular driving applications such as platooning. A group of vehicles can negotiate and drive jointly close to each other in a cooperative manner …

Secure Reconfigurable Computing Paradigms For The Next Generation Of Artificial Intelligence And Machine Learning Applications, Brooks Olney

USF Tampa Graduate Theses and Dissertations

The fields of artificial intelligence (AI) and machine learning (ML) have been popular tools for data analysis at the edge, particularly through complex deep and convolutional neural networks (DNNs/CNNs), which can learn to parameterize a function given a labeled dataset. Indeed, these technologies have enabled significant progress across a wide range of fields and are becoming ubiquitous. However, training the best model for an application and subsequently using them to evaluate data in real-time requires an immense amount of computational power. Typically, ``smart" sensors at the edge rely on the cloud to accelerate this computation due to power and compute …

Exploring Time-Varying Extraneous Variables Effects In Single-Case Studies, Ke Cheng

USF Tampa Graduate Theses and Dissertations

The effect of time-varying extraneous variables has been studied in other statistical analyses such as using Kaplan–Meier or Cox regression analysis in survival analyses. Nonetheless, the effect of modeling versus not modeling individual specific time varying extraneous variables has not been explored in multiple-baseline single case designs through Monte Carlo simulation studies. Therefore, in my dissertation, I used simulation methods to explore for a variety of conditions (varying in the number of participants, number of observations per participant, type of extraneous variable effect, size of the true intervention effect) the impact of extraneous variables on bias and standard error of …

Standing Her Ground: Legal Constraints On Women Who Have Been Victims Of Violence, Janae E. Thomas

USF Tampa Graduate Theses and Dissertations

Women who have been the victim of violence have always been at a disadvantage under the laws in the United States because these laws stem from a patriarchal, sexist, heteronormative, and racist ideology under which this country was founded. Self- defense laws have shown to be no different and serve as a constraint to women who attempt to protect themselves at the hands of an abuser. This dissertation focuses on women who have been the victim of violence at the hands of an abuser to show that the law is not doing an adequate job of protecting them. It accomplishes …

Please Don’T Label Me: An Examination Of Black-Owned Labels And How A Positive Consumer Activism Movement May Have A Negative Outcome, Khalia C. Jenkins

USF Tampa Graduate Theses and Dissertations

The Covid-19 crisis that began in 2020 brought to light many societal issues as people had time to sit and reflect. One of these issues is the systemic injustices against African Americans, which were highlighted after the death of George Floyd. This event re-ignited the Black Lives Matter movement amongst U.S. citizens of all races and within corporations. While some companies pledged to donate to various Black causes, others opted to empower Black businesses economically by supporting the Buy-Black Movement. One of the ways they are accomplishing this goal is by adding a Black-owned label to products and businesses. While …

Chasing A Moving Target: Examining Shifts In Elementary Teachers' Language And Conceptions Of Digital Literacy During Professional Learning, Stephanie M. Branson

USF Tampa Graduate Theses and Dissertations

Emerging and transforming innovations carry with them new ways of conceptualizing literacy practices in the classroom. As the technology revolution forges ahead and permeates the elementary school setting, teachers must consider how they talk about and model digital literacy practices. Digital literacy goes beyond merely operating technology tools and devices. It includes the cognitive and social processes that take place when reading, writing, and communicating in digital spaces and with digital tools. To understand the integration of digital literacies into the classroom, we must better understand how teachers develop digital literacy competencies and dispositions through focused and intentional professional learning …

Turmoil In The Workforce: Introduction Of The Nomadic Employee, Catrina Hopkins

USF Tampa Graduate Theses and Dissertations

This phenomenological study is designed to define a “nomadic employee,” a figure who has emerged in the ever-changing labor force, and to define what drives these workers to move between companies within a short period of time (generally within a 12-month period). These nomadic employees are driving higher turnover rates and causing rising onboarding costs. Relationships between employees and their employers have changed drastically in recent decades. Business concepts have evolved, and, thus, so have employee motivations. With the introduction of the millennial generation into the workforce and the emergence of the technology revolution, workforces have transformed, again establishing the …

Attention-Grabbing Tactics On Social Media, Arjun Kadian

USF Tampa Graduate Theses and Dissertations

News posts are popular among social media users. Since news reading is critical for both social media platforms and news providers, the use of attention-grabbing tactics, such as hyperbole and expressed emotional arousal, is commonplace to increase news readership. However, there is scant empirical evidence to explain the impact of attention-grabbing tactics on social media users’ reading intentions and behavior in social media. Therefore, I first explore how and why the use of hyperbolic statements in news headlines influences users’ interest and intention to read the news. Drawing on expectation violation theory, I propose competing hypotheses. I conducted three experiments …

Intimate Conversations: A Mixed-Methods Study Of African American Father-Adolescent Sexual Risk Communication, Shanda A. Vereen

USF Tampa Graduate Theses and Dissertations

Background: Approximately 50% of African American (AA) high school students are sexually active and a large proportion of sexually active AA students report engaging in sexual risk behaviors such as not using condoms at last intercourse. Consequently, AA adolescents in the United States experience outcomes of risky sexual behaviors at high rates. Evidence shows parents have an effect on shaping adolescent attitudes, values, and beliefs regarding sex through sexual risk communication (SRC). Although parent-adolescent SRC is associated with reductions in sexual risk behaviors among AA adolescents, research has primarily focused on mothers. While parents acknowledge that SRC is traditionally viewed …

Prepare For, Respond To, Recover, And Learn From Disasters: Using Data-Driven Methods To Model And Understand Disaster Resilience, Jinwen Xu

USF Tampa Graduate Theses and Dissertations

Community resilience reflects the ability of human communities to prepare for, respond to, recover, and learn from disastrous events. Community resilience carries different meanings in different phases of disaster management (i.e., preparedness, response, recovery, and mitigation). With the emergence of new geospatial data sources, human activities now can be captured through social media, mobile signals, and nighttime illuminations, which makes it possible to describe the conditions among various communities before, during, and after disasters. Therefore, this dissertation explored the use of different types of geospatial data sources (social media, nighttime light remote sensing, land-use data, and census survey data) during …

USF Tampa Graduate Theses and Dissertations

Use of Extended Reality (XR) technology such as Augmented Reality (AR) and Virtual Reality (VR) has experienced significant growth, with continuous advances in mobile technology and head-mounted display (HMD) headset development. As applications that span more than one type of reality have started to emerge, there is a need for additional research regarding the user interfaces (UIs) developed for these multimodal systems. While some work exists towards the creation of UI design guidelines in AR and in VR, little to no work has been done in providing recommendations for designing interfaces that work successfully across multiple XR modalities. To explore …

Methadone Patients In Vietnam: Substance Use Patterns, Reasons For Entering Treatment, And Methadone-Related Attitudes, Tram Hoang Huyen Tran

USF Tampa Graduate Theses and Dissertations

Objectives. Vietnam has high rates of opioid addiction, but methadone maintenance treatment (MMT) only became available in Vietnam in 2008. To date, MMT has expanded nationwide serving about 51,000 patients. As MMT is relatively new in Vietnam, additional research on methadone patients is still needed. This dissertation aims to address two important issues related to MMT that have been understudied: the extent/type of substance use (SU) among MMT patients in Vietnam; and the low utilization of MMT among women.

Methods. This dissertation contains three separate, but related studies. Study 1 systematically reviewed 20 studies and summarized the literature on the …

Saudi Parents As Advocates For Their Young Children With Disabilities: Reflections On The Journey, Sadeem A. Alolayan

USF Tampa Graduate Theses and Dissertations

Although special education advocates have played an essential role in obtaining rights for individuals with disabilities, there is still much unknown about their motivations, challenges, roles, and the meaning they made from their experiences. Research into Saudi parent advocates of children with disabilities and their complex daily life issues have seldom been investigated, with rare studies that focus solely on Saudi early intervention services needs and supports. This qualitative study aimed to explore the experiences of Saudi parents of children with developmental disabilities who are special education advocates in their communities. One of the goals of this study was to …

Relationship Between Demographic Characteristics And Internship Participation Of Senior Undergraduate International Students, Timothy W. Gjini

USF Tampa Graduate Theses and Dissertations

The United States higher education institutions’ mission is to support students' academic success and career development goals by preparing them to become globally competent citizens and workforce-ready graduates. With student workforce preparation at the core of their mission, there is concern that colleges and universities are not adequately investing in international students’ engagement in career-preparation practices (e.g., internships). As such, this quantitative, secondary-data study explored the relationship between senior international students’ demographic characteristics, the institutional environment (type and classification), and their internship participation behavior. Key variables were identified from three complementary theoretical strands, including Astin’s Input-Environment-Output (I-E-O) Model (1988, 1993a, …

Transformative Psychedelic Experiences At Music Events: Using Subjective Experience To Explore Chemosocial Assemblages Of Culture, Gabrielle R. Lehigh

USF Tampa Graduate Theses and Dissertations

Clinical interest in psychedelic treatments in the United States started in the 1950s, but anti-drug policy and anti-social sentiments quickly thwarted future research. The last decade has renewed clinical interest in using psychedelics to treat a diversity of mental health ailments. While these studies provide essential protocols, treatments, and therapy models for patients, they are limited in understanding the role of the contextual elements that influence psychedelic experiences and outcomes. This project examines how people use psychedelic substances outside medical settings by studying transformative psychedelic experiences at music events. This inquiry into psychedelic use utilizes an integrated framework of chemoethnography …

Motherhood In The Multiverse: Melodrama And Asian American Identity In Everything, Everywhere, All At Once, Aditya Sudhakaran

USF Tampa Graduate Theses and Dissertations

In what follows, I look to the visual and narrative composition of the multiverse between Everything, Everywhere, All at Once (The Daniels, 2022) and Doctor Strange: Multiverse of Madness (Sam Raimi, 2022) to develop a more precise understanding of the superhero blockbuster as a contemporary expression of sensation melodrama. To do so, I use two depictions of maternity to excavate two very different approaches to the multiverse: one that externalizes social conflict, which it answers with individuated and exculpatory violence, and another that internalizes social conflict, which it answers through collective care. I introduce the blockbuster’s mobilization of the multiverse …

Evaluating Foot-Drop Interventions For Multiple Sclerosis Using A Multimodal System, Laura Marie Byrnes-Blanco

USF Tampa Graduate Theses and Dissertations

This dissertation explores how multimodal walking impacts quantitative and qualitative aspects of gait for persons with multiple sclerosis (pwMS) experiencing foot-drop. Foot-drop can dramatically impede mobility and clinicians routinely prescribe ankle-foot-orthosis (AFO) and functional electrical stimulation (FES) devices to alleviate its impacts on daily life. However, little is known about how these devices affect pwMS while traversing environments with real-world complexity. To explore this topic, an interventional, parallel assigned study was conducted. A realistic nature pathway containing changes in floor pitch, audiovisual stimulation, and during-trial tasks (for dual-tasking) was generated in an immersive virtual reality system called CAREN: Computer Assisted …

Organizations Ensuring Resilience: A Case Study Of Cortez, Florida, Karla Ariel Maddox

USF Tampa Graduate Theses and Dissertations

“Resilience” has often been defined by examining case studies in resilience failures. In contrast, this case study utilizes the oldest, still functional fishing village in Cortez, Florida to rhetorically analyze how organizational communicative practices have worked to ensure its resilience. Situating this conversation within Rhetoric proves valuable since so many attempts to define and utilize “resilience” seek to capitalize on its positive connotation but distort resilience definitions and practice. This dissertation explores three research questions: 1. “What systems and/or structures made our continued existence possible and what ideologies or goals drove their creation?” 2. “What ideologies, perceptions, and/or goals inspired …

Self-Determination And The Lived Experience Of Employed Adults With Intellectual Disabilities: An Interpretative Phenomenological Analysis, Abdelrahman Mohammad Alzarie

USF Tampa Graduate Theses and Dissertations

Literature reveals that self-determination is a critical predictor of employment at the post-secondary level for individuals with Intellectual Disabilities (ID). However, current research concerning self-determination in the post-secondary work of individuals with ID is scarce and primarily focused on the perspectives of parents or educators or has been driven by evaluating learning models of self-determination. Furthermore, individuals with ID were not adequately represented as participants in the current research, and their voices were not given the opportunity to be heard. Therefore, this qualitative phenomenological study aimed to explore the lived experience of six Saudi employed adults with mild ID who …

The Development Of A Behaviorally Based Mentoring Workplace Scale, Christina N. Falcon

USF Tampa Graduate Theses and Dissertations

The purpose of this research is to contribute to the mentoring literature by providing a new tool to measure mentoring behaviors and their effectiveness from the perspective of the protégé. To accomplish this, I used the specific mentoring behaviors outlined by previous research to develop a behaviorally based measure of mentorship. The items for this new behaviorally based mentoring effectiveness scale were developed to measure the same theoretical construct as previous mentoring scales, but with the intention of capturing effective behaviors instead of broader mentoring functions. This scale was developed through three main steps: a pilot study to narrow down …

Who Goes And Who Stays: Predicting Hurricane Evacuation For Local Neighborhoods, Shakhawat Hosen Tanim

USF Tampa Graduate Theses and Dissertations

To reduce the devastating impacts of hurricanes on people’s lives, communities, and societal infrastructures, disaster management would benefit considerably from a detailed understanding of evacuation, including the socio-demographics of the populations that evacuate, or stay, down to disaggregated geographic levels such as neighborhoods. A detailed household evacuation prediction model for local neighborhoods requires both a robust household evacuation decision model and individual household data for small geographic units. To address the first of these, this dissertation performed a statistical meta-analysis of numerous survey-based hurricane evacuation studies to establish mean effect sizes for predictors impacting the household decision. To address the …

Bioinformatic Analysis Predicts Microglial Dysfunction In Murine Aging, Amadu Idrisa Jalloh

USF Tampa Graduate Theses and Dissertations

Age-related disease is a growing concern as the global geriatric population increases. Neurodegenerative diseases scale unfavorably in prevalence with aging and inflict disastrous consequences to human health and well-being. These disorders are challenging to investigate because they arise from complex molecular origins. The neuroimmune system is a common factor among these diseases and microglia play an important role in maintaining homeostasis in the central nervous system. Aging progressively impairs microglia by decreasing their ability to adapt and respond to noxious environmental stimuli or injury. Microglial dysfunction aggravates neurodegenerative pathology when microglia are unable to regulate neuroinflammation effectively. We investigated aging …

L2 Writer Identity Construction In Academic Written Discourse: A Multi-Case Study, Beibei Ren

USF Tampa Graduate Theses and Dissertations

Writer identity has gradually become a focus in writing scholarship in recent years. From a social constructivist lens, writer identity is not optional; it resides in all texts. And it is a construct that does not exist in a vacuum, but is shaped by the sociocultural and academic context, and simultaneously individual writers agentively selected from the socially available repertoire to construct their identities in text. Departing from social constructivism, this study adopted Ivanic’s (1998) conceptualization of writer identity, which consists of autobiographical self, discoursal self, self as author and possibilities for selfhood, and highlighted the role of agency in …
