A Multi-Faceted Approach To Understanding Acceptability Of Docs K-5: A Qualitative Analysis, Andrea Guarnieri

USF Tampa Graduate Theses and Dissertations

This qualitative study investigated the acceptability of DOCS K-5, a behavior parenting program adapted for parents of elementary aged children. Despite proven efficacy in preventing maladaptive behaviors, parenting programs have historically suffered from low attendance and engagement. Participants (N = 13) attending the pilot DOCS K-5 program took part in six group interviews while enrolled in the program to examine the facilitators and barriers to attendance, perceived effectiveness, and collateral benefits received from participation in the program. This study considered possible cognitive, affective, instructional, and pragmatic facilitators or barriers to attendance and engagement. Participants described motivations to learn various types …

How Culture And Storytelling Can Influence Urban Development: An Ethnographic Look At The Community-Driven Revitalization Of Newtown In Sarasota, Florida, Michala Head

USF Tampa Graduate Theses and Dissertations

When Americans think of Florida, tourist attractions often trail the initial thoughts of alligator sand chaos. Disneyworld and its neighboring parks are set up for optimal experience and consumption, the thought of a trip South along the coast for a sweltering beach day, sipping on a frozen drink in January sings to Midwesterners. For residents of these seaside cities, such as Sarasota, the experiences of the space are much more complex. Within the broader contexts of the resurgence of the Black Lives Matter movement following the murder of George Floyd and a global pandemic that impacted America’s marginalized populations disproportionally, …

Data-Driven Studies On Social Networks: Privacy And Simulation, Yasanka Sameera Horawalavithana

USF Tampa Graduate Theses and Dissertations

Social media datasets are fundamental to understanding a variety of phenomena, such as epidemics, adoption of behavior, crowd management, and political uprisings. At the same time, many such datasets capturing computer-mediated social interactions are recorded nowadays by individual researchers or by organizations. However, while the need for real social graphs and the supply of such datasets are well established, the flow of data from data owners to researchers is significantly hampered by privacy risks: even when humans’ identities are removed, or data is anonymized to some extent, studies have proven repeatedly that re-identifying anonymized user identities (i.e., de-anonymization) is doable …

Phenotypic Diversity And Costs Of Early Hatching In Lizards, Zachary Winstead

USF Tampa Graduate Theses and Dissertations

Early hatching is a form of environmentally cued hatching in which embryos can emerge early to improve chances of survival and is considered a means of antipredator defense. Early hatching as a response to predation has been well documented in amphibians, but its prevalence among other animal groups is unknown. Moreover, any trade-offs between early hatching and other traits, and thus survival, are not well understood. There is anecdotal evidence that lizards exhibit early hatching behavior, but quantitative evidence is limited to one study. In the present study, I tested for the presence of early hatching in six species of …

Analysis Of Post-Traumatic Stress Disorder Gene Expression Profiles In A Prospective, Community-Based Cohort, Jan Dahrendorff

USF Tampa Graduate Theses and Dissertations

Post-traumatic stress disorder (PTSD) is a common and debilitating psychiatric disorder that may occur in individuals exposed to traumatic events such as accidents, interpersonal violence, war, combat-exposures or natural disasters. PTSD is a significant public health issue with a high disease burden associated with substantial health care costs and several comorbidities negatively affecting an individual’s quality of life. The biological underpinnings of the disorder are not well understood. Gene expression studies can shed light into the complex physiology of PTSD. However, to date, studies employing a hypothesis-free approach examining the whole transcriptome are scarce and are limited to assessment of …

Native And Non-Native English-Speaking Doctoral Students' Strategies To Understand Idiomatics In Comics And Comic Strips, Himelhoch Luz-Aydé

USF Tampa Graduate Theses and Dissertations

Everyday language consists of many idiomatic and figurative expressions. For non-native English speakers to achieve native fluency, control of idiomatics—native speech that includes the use of both idiomatic and figurative language—is paramount. In this study, I aimed to explore the use of comics and comic strips in the learning and comprehension of L2 (second language) idiomatics. Seldom has the topic of comics and comic strips been addressed as it applies to idiomatics learning in second language acquisition (SLA). I employed a descriptive and exploratory approach in this study to address this gap in SLA pedagogy. A total of 21 doctoral …

Flow Visualization And Aerosol Characterization Of Respiratory Jets Exhaled From A Mannequin Simulator, Sindhu Reddy Mutra

USF Tampa Graduate Theses and Dissertations

It is important to understand the airborne transmission of infectious diseases due to the COVID-19 pandemic. Physical experiments were conducted to understand the dispersion of aerosols emitted from a mannequin simulator replicating human tidal breathing through the nose and mouth with and without a protective face mask in an enclosed space. Flow patterns are observed via high-speed visualization, and the concentration and size distribution of the particles is measured as a function of distance from the mannequin using an optical particle sizer. Masks were shown to effectively reduce the horizontal dispersion of aerosol for both mouth and nose breathing. Further, …

The Extended Parallel Processing Model (Eppm) And Risk Perceptions Of Twitter Messages Related To Covid-19, Muhammad E. Rasul

USF Tampa Graduate Theses and Dissertations

Since its genesis, the novel coronavirus or COVID-19 has claimed millions of lives across the world and has infected many more. The population in the US experienced one of the worst outbreaks of COVID-19 in the world, with the number of deaths rising monolithically at one point. Although the development and inoculation of a large number of the public has helped, newer variants threaten to revitalize the growth and spread of COVID-19. Scholars have extensively studied health messages related to COVID-19 in a variety of contexts. However, little attention has been paid to the risk perceptions of health messages related …

Influence Of Coating Defects Within The Lock Seams On The Corrosion Performance Of Aluminized Steel Drainage Pipes, Mohammed Al Yaarubi

USF Tampa Graduate Theses and Dissertations

The electrochemical behavior of aluminized steel is investigated to determine the corrosion performance of coating deficiencies generated within the lock seams during the fabrication of aluminized steel corrugated pipe. Electrochemical techniques and visual and profilometric analysis are used to assess the ability of the aluminum and zinc coating to provide sufficient galvanic protection to the underlying steel in the presence of a crevice. Also, Crevice coupons and lock-seam samples were used in this investigation in different environmental conditions simulating natural water conditions to relate the corrosion rate with the level of protection that the coating will provide. In addition, a …

The fourth industrial revolution or Industry 4.0 has changed today’s manufacturing scenario. The transition to smart manufacturing technologies has been evolving over the last few years and has recently accelerated due to the pandemic. The need to make manufacturing systems agile, adaptive, resilient, and robust has expediated the adoption and implementation of smart manufacturing technologies.

Despite the interest of manufacturers in smart manufacturing, the adoption rate has been slow due to the lack of decision-making tools that can provide a clear strategic roadmap for effective execution. Small and medium sized enterprises (SMEs) are especially slow in adoption due to the …

Metabolic Rate, Critical Oxygen Partial Pressure, And Oxygen Supply Capacity Of Farfantepenaeus Duorarum At Their Lower Thermal Limit, Alexandra L. Burns

USF Tampa Graduate Theses and Dissertations

Temperature and environmental oxygen availability affect oxygen supply and demand in ectotherms, which are hypothesized to control the geographic limits of many marine species. The oxygen supply capacity (α) is calculated from commonly measured metabolic traits, including the standard metabolic rate (SMR) and critical oxygen partial pressure at SMR (Pcrit). It may be used to estimate the metabolic capacity and aerobic scope across changes in temperature and oxygen partial pressures as α reflects adaptations of the cardiorespiratory system to meet maximum energy demands at a given oxygen partial pressure (PO2). In this study, α was measured for the Tampa Bay …

Examining The Presence Of A Possible Species Complex Of Octopus Joubini (Cephalopoda: Octopodidae) In The Eastern Gulf Of Mexico, Haley Holloway

USF Tampa Graduate Theses and Dissertations

The Pygmy Octopus Octopus joubini (Robson, 1929) is a small, shallow water species found throughout the Gulf of Mexico (GoM), western Atlantic Ocean and the northeastern Caribbean Sea (Mather, 1982; Jereb & Roper, 2014; Judkins, 2009). This species is believed to belong to a complex based upon morphological features including arm length, web depth, sucker size, egg size, hatchling ecology, and chromatophore coloration. It has been proposed that Octopus mercatoris, another pygmy species found in the GoM, may belong in this complex; however, no analyses have been performed to verify this claim. The present study incorporated morphological comparisons with …

Pre-Service Teachers' Knowledge Of The Brain: Implications For Autonomy-Supportive And Controlling Motivational Styles, Katie Jansen

USF Tampa Graduate Theses and Dissertations

Neuromyths, or misconceptions about the brain and learning that are rooted in scientific fact, have been documented among educators across various subject areas and educational levels throughout the world. The endorsement of neuromyths may affect the ability of educators to support the psychological needs of their students. The present study examined neuromyth endorsement and neuroscience literacy among pre-service educators, as well as their orientations toward autonomy-supportive or controlling motivational styles. Associations between pre- service teachers’ knowledge of the brain (i.e., neuromyth endorsement and neuroscience literacy) and their motivational styles (i.e., autonomy-supportive or controlling) were also explored. Data were gathered from …

Transparent Planar Micro-Electrode Array For In-Vitro Electric Field Mediated Gene Delivery, Raj Himatlal Shah

USF Tampa Graduate Theses and Dissertations

Gene delivery is the process of delivering the modified gene into the human cell. There are two types of gene delivery depending on where the target cells are. The in-vivo gene delivery deals with delivering the altered genes into the cells while still in the host body. While another approach is to extract the cells from the host body, transfer the modified gene into cells and then put these cells back into the host body, this approach is called the ex-vivo method.

A vector is a carrier that carries the modified gene to the host cell or body. Hence, depending …

Recognizing Patterns From Vital Signs Using Spectrograms, Sidharth Srivatsav Sribhashyam

USF Tampa Graduate Theses and Dissertations

Spectrograms extract frequency components from a signal. Spectrograms have beenin use for a long time mainly to analyze frequency components in audio signals. Typically, these audio signals have a very high sampling rate, various frequency components and high frequency variability with time. Vital signs on other hand have very low sampling rate with no frequency variability. This work explores if spectrograms can be used to analyze and recognize patterns from vital signs signals.

As mentioned above, spectrograms deal with frequencies. More the variability of frequency, better the patterns emerge when spectrograms are applied on the signals. As vital signs lack …

The future of water security in the U.S. is clouded by the progression of anthropogenic climate change and the increasing number of households unable to afford access to safe drinking water, while advances in detection and potential health risks of trace organic contaminants are constantly moving the water treatment finish line. There is a need for sustainable, economically feasible technology to provide the means to meet increasingly stringent water quality regulations while also ensuring current standards are met for all communities. Biologically active filtration, combined with an operational approach designed to optimize contaminant removal by the biofilm, may enable water …

Mitigating Negativity Bias In Media Selection, Gabrielle R. Jarmoszko

USF Tampa Graduate Theses and Dissertations

A growing body of research explores implicit negativity bias and how it influences news selection processes of media consumers. However, very little, if any, research exists exploring how negativity bias in the news selection process can be mitigated. Informed by experimental designs that have proven effective in mitigating other types of implicit bias, this study aimed to investigate whether having consumers commit themselves to definitions of their preferred type of news before engaging in the selection process alters manifestations of negativity bias in the selection. This study tested two hypotheses: H1, that non-committed individuals will have a higher selection frequency …

Low-Cost Device For Laser Phacoemulsification: A Preliminary Study, Mitchell Harrah

USF Tampa Graduate Theses and Dissertations

The current gold standard of cataract removal surgery is phacoemulsification systems. These are divided based on the type of devices used; both are considered equal but with different delivery modes. These delivery methods are either acoustic or light-based. However, these devices pose two hurdles for impoverished areas: high costs and heavy resource usage. This thesis proposes a novel phacoemulsification system is based on the low-cost, off-shelf laser diodes that implement light-based phacoemulsification of cataracts. The system is tested for viability over two methods: finite element analysis and experimentation on various phantoms. Simulations on the device have occurred on the COMSOL …

Field And Remote Sensing Analysis Of The 2015 Pyroclastic Density Currents At Colima (Mexico) And Calbuco (Chile) Volcanoes: Implications For Hazard Assessment And Crisis Management, Elodie Macorps

USF Tampa Graduate Theses and Dissertations

Although one of the most spectacular phenomena of active volcanoes, Pyroclastic density currents, or PDCs, are considered the most dangerous volcanic hazards. PDCs are avalanches of hot volcanic gases, ash, and larger volcanic fragments that travel at incredible speed down the flank of a volcano. High dynamic pressures, high temperatures, and high velocities are the primary dangers associated with PDCs and lead to near-complete destruction and death.

I use a multi-disciplinary approach to study the deposits left behind by PDCs, in order to understand their dynamics, their interactions with the receiving landscape, and their final distribution, starting on the ground …

Measuring State Empathy: Exploring The Efficacy Of A Film Clip Task And Examining Individual Differences In Empathic Responding, Stephanie R. Hruza

USF Tampa Graduate Theses and Dissertations

The study of trait empathy and the experience of empathy has implications for psychopathologies, the enactment of prosocial behaviors, and inhibition of aggression. For the most part, studies on empathy have been limited to the examination of trait empathy and/or empathy-related prosocial behaviors. However, to better understand how trait empathy may translate into empathy-related behaviors, it is important to find the best ways to elicit and measure state empathy, as well as characterize the relationship between trait and state empathy. Additionally, research into the relationship between normal-range personality traits and empathy on both a trait and state level has largely …

Reference-Dependent Choice On Digital Platforms, Joshua K. Kaisen

USF Tampa Graduate Theses and Dissertations

Throughout this dissertation I explore a significant departure from the standard model of rationality known as reference-dependence. The theory reference-dependence asserts that an individual’s choice is dependent on their frame of reference established through factors divorced from their rational cost and benefit. This behavior is inefficient as individuals fail to rationally optimize their payoffs. This behavior is understudied in natural settings where isolating specific stimuli which may establish a reference is challenging. However, digital platforms contain limited stimuli which are fully observable to researchers and present an ideal setting to study the theory of reference-dependence. Thus, I introduce three new …

Site Suitability Modeling In The Sand Pine Scrub Of The Ocala National Forest, Jelane M. Wallace

USF Tampa Graduate Theses and Dissertations

Central Florida’s Ocala National Forest is the largest remnant of the unique-to-the-region Sand Pine Scrub ecosystem. This ecosystem exhibits a surprising wealth of biodiversity despite what may be characterized as barren, difficult, dry, pyrogenic conditions. Significant prehistoric sites exist throughout the forest, even in the Sand Pine Scrub; however, most are on the margins and few systematic surveys penetrated this ecosystem, until now. I utilized GIS and these recently collected archaeological survey data, in conjunction with other environmental, geological, or historical data in GIS format, to model prehistoric settlement and land use patterns. This model attempts to address questions of …

Racial Threat Theory: A Test Of The Economic Threat Hypothesis, Carl L. Reeds

USF Tampa Graduate Theses and Dissertations

Racial disparities in the criminal justice system are well documented. While one potential contributor to these disparities may be differential offending on the part of racial groups, another alternative or additional explanation is racial discrimination. Blalock developed racial threat theory to explain macro-level discrimination. According to this theory various forms of “threat” posed by minority populations to majority populations leads to more formal social control or disparate formal social control, such as the formal social control that is imposed by the criminal justice system. According to Blalock, “economic threat” occurs when the Black population has large or increasing economic resources …

The Role Of Antecedent Music In The Running Routines Of Experienced Runners, Jennifer L. Cook

USF Tampa Graduate Theses and Dissertations

Promoting running as an accessible and cost-effective form of exercise is important because persistent runners have a 29 to 50% lower risk of cardiovascular mortality compared to those who never run (Lee et al., 2014). Although there is a body of research on music and running, the results have been inconclusive across the literature. This may be due to a reliance on self-report measures and the averaging of results employed with group designs. To address these issues, the current study measured performance (pace) as the primary dependent variable in a series of within-subject designs. First, an online cross-sectional survey (Study …

Affectivetda: Using Topological Data Analysis To Improve Analysis And Explainability In Affective Computing, Hamza Elhamdadi

USF Tampa Graduate Theses and Dissertations

We present an approach utilizing Topological Data Analysis to study the structure of face poses used in affective computing, i.e., the process of recognizing human emotion. The approach uses conditional comparison of different emotions, both respective and irrespective of time, with multiple topological distance metrics, dimension reduction techniques, and face subsections (e.g., eyes, nose, mouth, etc.). The results confirm that our topology-based approach captures known patterns, distinctions between emotions, and distinctions between individuals, which is an important step towards more robust and explainable emotion recognition by machines.

A Self-Study Of Need-Supportive Teaching In Elementary Art, Craig Jacobowitz

USF Tampa Graduate Theses and Dissertations

I present a self-study of my need-supportive teaching practice. I have long been curious about what it is about my teaching, what I say and do, that motivates students to work harder on their artwork and persevere when they become mired in difficulties. Need-supportive teaching addresses students' basic psychological needs within the classroom setting through high-quality teacher/student relationships and structure. Need-supportive teaching, motivation, and academic resilience are areas I made an extensive study of, as presented in chapter two. In March of 2020, the educational landscape in the United States was altered by the arrival of the unprecedented and novel …

Cognitive Ability And Ambivalence Toward Alcohol: An Examination Of Working Memory Capacity’S Influence On Drinking Behavior, Emily T. Noyes

USF Tampa Graduate Theses and Dissertations

Research stemming from dual-processing theories suggest that working memory capacity may have an important role in the ability to inhibit automatic tendencies when there is the motivation to do so (Barrett, Tugade, & Engle, 2004). Ambivalence, the simultaneous desire to engage in (approach motivation) and inhibit (avoidance motivation), often occurs with problematic behaviors like alcohol abuse. The current study sought to determine whether individual differences in working memory capacity moderate the relationship between approach, avoidance and subsequent drinking behavior in a clinical sample. A total of 66 individuals with alcohol use disorder (AUD) participated in a baseline assessment of working …

Mental Health Problems, Traumatic Brain Injury, And Offending Behavior Among Persons Incarcerated In A County Jail, Lauren F. Fournier

USF Tampa Graduate Theses and Dissertations

Previous work has found that although mental illness is positively related to offending behavior, it is a fairly poor predictor of aggression, violence, offending, and recidivism after controlling for sociodemographic and historical risk factors (i.e., criminal history, age, race, gender). This refutes the model that mental illness is a direct cause of crime. Instead, risk for recidivism or crime related to mental health problems may be higher when combined with other risk factors. The current study evaluated traumatic brain injury (TBI) and associated symptoms of post-concussion syndrome (PCS) as potential moderators of the relationship between mental health problems and concurrently …
