A Functional Optimization Approach To Stochastic Process Sampling, Ryan Matthew Thurman

USF Tampa Graduate Theses and Dissertations

The goal of the current research project is the formulation of a method for the estimation and modeling of additive stochastic processes with both linear- and cycle-type trend components as well as a relatively robust noise component in the form of Levy processes. Most of the research in stochastic processes tends to focus on cases where the process is stationary, a condition that cannot be assumed for the model above due to the presence of the cyclical sub-component in the overall additive process. As such, we outline a number of relevant theoretical and applied topics, such as stochastic processes and …

A Comparison Of Accumulated And Distributed Reinforcer Arrangements In A Classroom, Alexandra Gingras

USF Tampa Graduate Theses and Dissertations

Though effective classroom management can increase student academic achievement and decrease disruptive behavior (e.g., Beaman & Wheldall, 2000; Marzano et al., 2003), many classroom teachers receive inadequate training on effective classroom management strategies (Reinke et al., 2011; U.S. Department of education 2000). Reinforcement-based interventions using differing reinforcer arrangements (e.g., accumulated, distributed) have been shown to be effective at reducing disruptive behavior (Fulton et al., 2019; Robinson & St. Peter, 2019); however, previous studies have not evaluated the relative efficacy of different reinforcer arrangements as teacher implemented classroom management strategies. Therefore, the purpose of this study was to assess the efficacy …

Through a team-based planning process that included the student and his classroom teacher, a function-based PTR intervention plan was implemented to address the student’s disruptive behavior and teach replacement behaviors of academic engagement and asking for help. An A-B design was used …

Self-Perceived Assessment Of Undergraduate Leaders Competencies Through A Leadership Development Program, Ryan D. Newton

USF Tampa Graduate Theses and Dissertations

This ex-post facto research study identified changes in participants’ self-perceptions of their competence in six key leadership competencies, as reported from a pre-training and post-training self-assessment. This study also identified the relationship between the participants’ self-reported changes and their persistence in enrollment at the University upon completion of the leadership training program. This quantitative study analyzed secondary data (N=201) from a large, four-year, public research institution in the southeast United States. Paired samples t-tests were used to determine that the self-reported change among participants was statistically significant (p<.05) from the pre- to the post-training self-assessment. Further, this study then examined the relationship between participants’ self-reported mean change and their persistence at the institution, defined as having graduated or continuing enrollment one year after completion of the leadership training program. A logistic regression was utilized to identify a negative predictive relationship between participants’ mean change and their likelihood of persistence. Implications for competency-based learning were discussed in relationship to student affairs practice.

Understanding Food Insecurity As A Multidimensional Construct: A Mixed Methods Approach To Assess Changes In Food Insecurity Status Among People Seeking Emergency Food Assistance, Whitney M. Fung Uy

USF Tampa Graduate Theses and Dissertations

Background: In the United States, 13.8 million households were food insecure in 2020, or 10.5% of the country’s population. Although the annual food insecurity rates remained stable between 2019 and 2020, largely due to increased COVID-19 pandemic relief efforts, many households experienced food insecurity and hardship at unprecedented rates. Food assistance provided by the largest government nutrition and food program, Supplemental Nutrition Assistance Program (SNAP), and emergency food providers (EFPs) such as food banks and pantries intended to provide short-term solutions have ended up as chronic, long-term methods of survival for many of these families, especially during COVID-19 and the …

The Career Decision-Making Self-Efficacy And Career Action Steps Of Humanities Students: A Quantitative Survey Analysis, Catherine Gorman Cordova

USF Tampa Graduate Theses and Dissertations

In an era of governmentally controlled education systems sustained through performance-based funding metrics, the value of higher education is often considered justified by socioeconomic impact and degree employability. Although modern academia traces its roots to the humanities and liberal arts for its foundation, degrees without direct job relation, and the students seeking these degrees, are often considered less employable than majors directly linked to vocations. However, the humanities and labor market are not mutually exclusive. Influenced by Social Cognitive Career Theory (SCCT) (Lent, et al., 1994), Self-Efficacy Theory (Bandura, 1977), and Career Maturity Theory (Crites, 1973), this cross-sectional quantitative survey …

Exploring The Relationship Between Student Expected Engagement And Referrals To The Behavioral Intervention Team, Makenzie R. Schiemann

USF Tampa Graduate Theses and Dissertations

Higher education administrators are tasked with supporting and retaining students with increasing needs. These needs often include emotional and mental health issues but can worsen to include suicidality and violence toward others. Traditional campus approaches for supporting students and intervening for violence, such as counseling and campus safety, have been reactionary rather than proactive. Behavioral Intervention Teams (BITs) have emerged as a mechanism for heading off violence before it occurs while also supporting students who may never engage in violence but need support. These teams were born out of the concept that violence is preventable and have grown into a …

Individual Differences In Response To Hostile And Benevolent Sexism In A Stem Interview Context: The Moderating Role Of Behavioral Activation, Elizabeth Kiebel

USF Tampa Graduate Theses and Dissertations

Women continue to face sexism in workplace contexts, especially those that are male dominated, such as science, technology, engineering, and mathematics (STEM). Yet, women often fail to confront the sexism they experience, despite confrontation being an effective way to cope with and prevent future harassment (Fitzgerald et al., 1995; Magley, 2002). To date, no one has assessed the potential moderating role of personality differences related to approach motivation on women’s confrontation of sexism. In this study, women were exposed to either a hostilely sexist or benevolently sexist question during a mock job interview that was purportedly being conducted as part …

Oral Narrative Interventions Implemented By Teachers, Speech-Language Pathologists, And Parents, Megan S. Kirby

USF Tampa Graduate Theses and Dissertations

Children’s oral language skills in preschool through early elementary grades can predict reading, writing, and social outcomes ten years into the future. Oral narrative language, which includes storytelling, is a long-established cultural practice in communities around the world. Narratives are the monologic re/telling of a real of fictitious event and people have used them for centuries to entertain, make sense of current and past events, and provide instruction. Oral storytelling does not require physical materials and can be tailored to the cultural and linguistic values of the community in which they are used. Thus, the portability, utility, and ubiquitous nature …

A Mixed Methods Analysis Of Maternal-Infant Feeding Interactions Between Dyads With Opioid Exposure, Kailey T. Rinaldi

USF Tampa Graduate Theses and Dissertations

Infants diagnosed with neonatal opioid withdrawal syndrome (NOWS) exhibit neurobehavioral dysregulation that may make them challenging to feed, potentially impeding positive early maternal-infant interactions. The goal of this study was to investigate dyadic behavior during the maternal-infant feeding interaction, specifically infant dysregulation and maternal sensitivity, between dyads with opioid exposure in the neonatal intensive care unit (NICU). This was a secondary data analysis using a mixed-methods design to analyze videorecorded feeding interactions of mothers with opioid use disorder (OUD) and their infants with NOWS. An integrative literature review investigating maternal sensitivity in mothers with OUD was conducted. Verbalizations expressed by …

A Statistical Method For Quantifying Animal Interaction; Combining Time Geography And Simulation, Zachary J. Smith

USF Tampa Graduate Theses and Dissertations

Dynamic interaction (DI) describes the synchronous interaction of one or more individual animals over time. Current methods to quantify DI from tracking data are lacking. They typically require synchronized tracking data which limits their applicability to most studies. They also often do not have built-in tests of significance to evaluate interaction, and if so, rely on random walk models that lack biological realism. This research aimed to develop and evaluate a new way of measuring animal interaction that overcomes these limitations. The goal was to create a statistical method for quantifying and evaluating interaction that is relevant across computational, behavioural, …

Comparing Participants In Discipline And Non-Discipline Specific First-Year Seminars: A Study On Student Characteristics, Expectations, And Changes In Major, Caroline Kaufmann Twachtman

USF Tampa Graduate Theses and Dissertations

First-year seminar (FYS) courses tend to focus on preparing students for successful academic and social integration into the college environment. Many of the studies on FYS courses focus on measuring outcomes such as college grades, retention, and graduation rates. While there is notable documentation of several different types of FYS courses, relatively few studies compare the different types of FYS courses. What, if any, differences might there be in the profiles of students who take either type of course? Is there a certain type of student that enrolls in the discipline-specific course, or a certain type of student that enrolls …

Breast Health Esteem To Motivate Breast Health Behavioral Intentions: An Application Of The Terror Management Health Model, Emily P. Courtney

USF Tampa Graduate Theses and Dissertations

Breast cancer is a pervasive disease affecting millions of people, and a family history of the disease can put individuals at a significantly higher risk of developing breast cancer over the course of one’s lifetime. In turn, women with a family history often perceive themselves as more susceptible to breast cancer. Further, women who have lost family members to breast cancer likely associate the disease itself with death to a greater extent. In addition to this increased risk perception, women with a family history might intertwine breast health with feelings of esteem. It follows that those feelings of esteem should …

Why Don’T They Just Ask?: Barriers To Directly Requesting Affirmative Sexual Consent By Gender And Sexual Orientation, Jessica A. Jordan

USF Tampa Graduate Theses and Dissertations

Most young adults report a discomfort with verbally and explicitly asking for sexual consent from a partner. Social scientists have theorized this discomfort is driven by conformity to rigid gender roles, sexual scripts, and peer norms, although little research has directly examined the relationship between these barriers and consent behaviors. Most consent research has focused on heterosexual individuals, and even fewer studies have compared the sexual consent attitudes and behaviors of heterosexual and sexual minority individuals. Through a series of three studies, I examined the reasons heterosexual and sexual minority young adults hesitate to ask a new partner for sexual …

Measuring And Improving Student Attitude In College-Level Chemistry: A Novel Survey Methodology And Social-Psychological Interventions, Ying Wang

USF Tampa Graduate Theses and Dissertations

Students’ attitude has been an important focus in the chemistry education community. However, there is a lack of research in evaluating interventions aiming to improve students’ attitude. Social-psychological interventions (SPIs), brief interventions that target students’ subjective experiences, were demonstrated to improve students’ attitude in instructional settings. In addition, accurately measuring students’ attitude helps researchers better understand the impact of the intervention. Therefore, the major goal of this work is to explore practices, particularly a novel survey methodology and a social-psychological intervention (SPI), to facilitate measuring and improving students’ attitude in college-level chemistry courses. This work also paid particular attention to …
