Examining The Role Of Executive Functions On The Intention-Behavior Gap Of Alcohol Harm Reduction Strategy Use, Becky K. Gius

USF Tampa Graduate Theses and Dissertations

Alcohol harm reduction strategies are health behaviors that aim to minimize the likelihood or severity of consequences associated with alcohol use. Despite the demonstrated usefulness of harm reduction strategies, there is variability in who and when the strategies are used, leading to the question “if they work, why not use them all the time?” One potential explanation is a discrepancy between the intention to drink safely and actually drinking safely, termed the intention-behavior gap. It is unclear to what extent college drinkers plan on engaging in safe drinking behaviors but fail to follow through. It is plausible some drinkers have …

Investigating Risk Factors Of The Development Of Compulsive Exercise And Eating Disorder Symptoms In College Students, Madeline Palermo

USF Tampa Graduate Theses and Dissertations

Compulsive exercise (e.g., high exercise frequency combined with the inability to reduce or stop exercising) is associated with a variety of maladaptive outcomes in college students, such as quality of life impairment, body dissatisfaction, and poor physical health outcomes. Recent research suggests that compulsive exercise is highly prevalent among college students and that engagement in compulsive exercise behaviors may increase over the first year of college. Given that college is an important developmental period for establishing behavioral patterns that affect long-term health, developing effective preventative interventions for compulsive exercise among early college students is paramount. Extant cross-sectional work suggests that …

An Experimental Study Of Negative Performance Feedback: Consideration Of A Cognitive Pathway And Individual Difference Factors, Ansley M. Bender

USF Tampa Graduate Theses and Dissertations

Negative performance feedback is relatively common and may be related to negative mental health outcomes, but there is a lack of sufficient experimental research. Further, little is known about the pathway by which effects emerge, or factors that may enhance or attenuate resilience to the effects of negative performance feedback. There is preliminary support for a cognitive pathway through appraisals of falling short of standards, but this specific model remains untested. Likewise, research suggests that perfectionism and positive future thinking may affect resilience in the context of negative performance feedback. The present study was among the first to experimentally test …

“You Don’T Seek Help, You Are Just Thankful For The Things The Country Provides For You.” The Emotional Burden Of Growing Up Undocumented In The United States, Melanie Anne Escue

USF Tampa Graduate Theses and Dissertations

For over a decade, the Deferred Action for Childhood Arrivals (DACA) program has provided more than 800,000 undocumented young adults with the ability to lawfully reside in the United States. Despite the program’s benefits, DACA falls short of offering long-term security and full societal integration. Over the past few years, political and legal attacks on the DACA program (e.g., actions of the former Trump administration, 2017 DACA recission, ongoing court proceedings) have made visible the precarious nature of the program and threatened the futures of young adults protected under the program. While prior studies have found that the growing anti-immigrant …

Examining The Complexity Of Cross & Collaborative Selling And Service-Sales Ambidexterity In Multi-Practice Professional Service Firms, Eduardo A. Suarez-Solar

USF Tampa Graduate Theses and Dissertations

What does it truly cost to acquire a new client? Managing Partners (MP) of Multi-Practice Professional Service Firms (MPPSF) have been asking themselves this question for years, mostly to no avail. The questions that should be deliberated are whether there exists an alternate method of acquiring new business in a more efficient, effective, and productive manner” and “whether such a procedure exists within the MPPSF that has not yet been fully developed? Neither of these questions can be determined until the following fundamental question is answered, namely whether and how does cross collaborative and service-sale ambidexterity sales occur within an …

On The Performance Enhancement Of Beamspace Mimo And Non-Orthogonal Multiple Access For Future Cellular Networks, Sinasi Cetinkaya

USF Tampa Graduate Theses and Dissertations

The ever-growing demand for higher data rates and greater data capacity at lower cost has led the mobile cellular industry to investigate new physical layer techniques and possible utilization of unused spectrums at higher frequencies for next-generation cellular networks. Thus, exploitation of the millimeter-wave (mmWave) spectrum and non-orthogonal multiple-access (NOMA) have been envisioned as the most promising enablers in meeting capacity demand. Due to the smaller wavelengths offered in mmWave frequencies, it is possible to deploy many antennas into a relatively smaller physical space in mmWave frequencies. This property leads to a promising integration between mmWave and massive multiple-input multiple-output …

“They’Re Still Trying To Wrap Their Head Around Forever”: An Anatomy Of Hope For Spinal Cord Injury Patients, William A. Lucas

USF Tampa Graduate Theses and Dissertations

This dissertation draws on ethnographic data to investigate the nature of spinal cord injury (SCI) rehabilitation in Central Florida, using participant observation and interview data to understand how people with SCI (pwSCI) conceptualize their own disabilities after experiencing such radical alterations in their subjectivities. Using case studies and ethnographic vignettes, it argues that the extreme double binds in which pwSCI find themselves (where they are personally ordinarily disabled and socially extraordinarily novel; and where they are enabled resources to pursue “hopeful” therapy modalities while being designated as hopelessly disabled) is further polarized by the various legislative regimes of truth in …

Transition To Higher Education In A College Assistance Migrant Program: Students’ Perception Of Purpose, Mark R. Lane-Holbert

USF Tampa Graduate Theses and Dissertations

The 21st century world is increasingly globalized and interconnected, and migration is a reality that substantially impacts the US educational system, and often requires specialized services for migrant students to successfully transition to higher education. While higher education has many benefits, it also presents inherent risks and challenges for students from migrant families, whose academic and life experiences may be vastly different from traditional college students. Federal collegiate transition programs like the College Assistance Migrant Program (CAMP) recognize this and aim to support students holistically throughout their transition to higher education. Such programs are in continual search of effective ways …

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 …

Pamam- Cyclodextrin Conjugate Upregulates Brain-Derived Neurotropic Factor In Arpe-19 Cells, Gopika Ashokan

USF Tampa Graduate Theses and Dissertations

Background: Traumatic Brain Injury (TBI) is a major contributor to death and disability due to motorvehicle accidents, sports, physical abuse, and battlefield injuries. The primary insult to the brain leads to inflammation, vascular dysfunction, and oxidative stress in the brain as well as in the eye. This leads to loss of Retinal Ganglion Cells (RGCs) and downregulation of Brain derived Neurotopic Factor (BDNF). BDNF is a neurotrophic factor that binds to Tropomyosin Receptor Kinase B (TrkB) receptor to promote cell growth, survival, and differentiation. Current treatment strategies do not promote neuronal regeneration. Therefore, novel treatments are needed to restore vision …

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 …

Data-Driven Learning Algorithm Via Densely-Defined Multiplication Operators And Occupation Kernels., John Kyei

USF Tampa Graduate Theses and Dissertations

Consider a nonautonomous nonlinear evolution $\dot{x}=f(x,t,\mu)$, where the vector $x(t) \in \mathbb{R}^n$ represents the state of the dynamical system at time $t$, $\mu$ contains system parameters, and $f(\cdot)$ represents a dynamic constraint. In most practical applications, the nonlinear dynamic constraint $f$ is unknown analytically. The problem of approximating $f$ directly from data measurements generated by the system is a main goal of this manuscript. In the postulates of the Nonlinear Autoregressive (NAR) framework, we show that the problem of approximating $f$ can be studied through symbols of densely defined multiplication operators over a Reproducing Kernel Hilbert Spaces (RKHS). In this …

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 …

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 …

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 …

Identifying Contributors To Disproportionality: The Influence Of Perception On Student Social, Emotional, And Academic Behavior Ratings, Chelsea Salvatore

USF Tampa Graduate Theses and Dissertations

Successful implementation of the MTSS framework involves equitable assessment and decision-making. This calls for researchers to investigate the processes utilized to identify students for early behavioral support, such as multi-informant universal social-emotional behavioral screening. The current study aimed to investigate this by first examining the usability of the Social, Academic, and Emotional Behavior Subscale (SAEBRS) and the student self-report version (mySAEBRS) across Black and White students in grades seven through nine. After examining these tools for measurement invariance, the trifactor model was employed with race as a predictor variable to examine the mean difference of Black and White students’ scores …

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 …

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 …

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 …

The Local Neurologies Of Substance Use Triggers, Breanne I. Casper

USF Tampa Graduate Theses and Dissertations

Substance use triggers are largely understood to be embedded in drug use contexts and to be a major precipitator of relapse. Yet, the relationship between triggers and future instances of drug use is not quite clear– particularly in understanding the nuances of when triggers are “triggering” and when they are not. Additionally, there is little ethnographic work that explores how individuals interact with triggers in contexts related to substance use, particularly during periods of active use. This project employs ethnographic and survey research methods to interrogate substance use triggers in the harm reduction context. In doing so, it answers the …

A Forward Genetic Screen Identifies Genes Involved In Gametocyte Development Of The Human Malaria Parasite Plasmodium Falciparum., Jyotsna Chawla

USF Tampa Graduate Theses and Dissertations

Transmission of the deadly malaria parasite Plasmodium falciparum from human to mosquito is achieved by specialized intraerythrocytic sexual forms called gametocytes. Circulating in the vertebrate host, relatively few intraerythrocytic gametocytes are picked up during a bloodmeal to continue sexual development in the mosquito vector. Human-to-vector transmission thus represents an infection bottleneck in the parasite's life cycle for therapeutic interventions to prevent malaria. Though the crucial regulatory mechanisms leading to gametocyte commitment have recently come to light, networks of genes that control sexual development remain to be elucidated. Here, we report a forward genetic approach to identify genes associated with gametocyte …

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 …
