Inside The Work Of A Rookie Principal Coach: Tackling Equity In Disciplinary Practices, Olayinka A. Alege

USF Tampa Graduate Theses and Dissertations

Hillsborough County Public Schools embarked on an ambitious goal to improve the highest-need schools by restructuring how the district supports schools and their leaders in July 2018. As part of this effort, the superintendent reduced the span of control and assigned principal coaches to support principals in a more intentional way. The purpose of this study was to explore how a principal coach engages a principal in examining inequities in disciplinary practices and how the principal coach provides the supports to prompt and sustain the principal’s efforts to reduce the disproportionate number of students of color being suspended from school. …

Prejudice Asymmetry: The Cultural Acceptance Of Sexism, Sophie Kuchynka

USF Tampa Graduate Theses and Dissertations

Sexism tends to be a culturally accepted form of prejudice. I propose the relatively strong trivialization of societal sexism stems from the unique benefits that men receive from the gender status hierarchy, compared to other types of group-based hierarchies. Three studies examined why people, men in particular, trivialize or justify gender bias in relation to other types of group-based biases. Study 1 was a correlational study that examined whether participants downplay the existence and social harm of gender bias in relation to racial, religious, and sexual orientation bias, moderated by participant gender. Participants reported stronger trivialization and denial of gender …

Conditions For Maximizing Expected Value In Repeated Choices From Experience, Andrea Y. Ranieri

USF Tampa Graduate Theses and Dissertations

It is largely expected that people can learn from past experiences and use this knowledge to make better decisions in the future. However, there are aspects inherent in experiential learning which may affect the extent to which people can extract and use information from experiential feedback to make advantageous decisions. Three aspects inherent in experiential learning were identified: (1) it is reliant on memory, (2) information is gathered exclusively through outcome feedback, and (3) outcome feedback is inherently dynamic. The current investigation explored how each of these aspects may help shape experiential decision making, and examined how the presence of …

Mapping Reward Values To Cues, Locations, And Objects: The Influence Of Reward Associations On Visual Attention, Constanza De Dios

USF Tampa Graduate Theses and Dissertations

Previous work has attempted to fit reward-driven attentional selection as being exogenous (stimulus-driven) or endogenous (goal-driven). However, recent work suggests that reward’s effects on attention depend on the type of stimulus feature that the motivational information is imparted during learning (incentive salience). If true, then reward should not be limited to solely impacting early perceptual or late categorization processes attention. The current study used event-related potentials (ERPs) to test the idea that reward’s effects on attention depend on the process that the reward information is embedded – early perceptual or late categorization. Results demonstrated reward-driven effects on perceptual representation when …

Stable Isotope Geochemistry Of Shelled Marine Invertebrates: Wide-Ranging Applications, Nasser M. Al-Qattan

USF Tampa Graduate Theses and Dissertations

Mollusks grow by adding discrete growth layers throughout their lifetime (i.e., accretion). More specifically, most marine mollusks precipitate their shells in oxygen isotopic equilibrium with seawater or with a constant offset from equilibrium. The stable oxygen isotope values (δ¹⁸O) of their shells are determined by the temperature and δ¹⁸O values of the surrounding water during calcification without significant vital effects. In comparison, the stable carbon isotope values (δ¹³C) of their shells reflect those of the dissolved inorganic carbon (δ¹³C- DIC) and respired carbon dioxide. Therefore, variations in the oxygen and carbon isotope …

Abelard's Affective Intentionalism, Lillian M. King

USF Tampa Graduate Theses and Dissertations

The work contained within this dissertation is a textual exegesis of Abelard’s ethics. The goal is to elucidate Abelard’s sort of intentionalism given his use of “intention” within his wider corpus, the grammatical and syntactical patterns in his prose, and Abelard’s own interests, biography, and situation as a twelfth-century monastic figure. As a result, this project should be understood as a history of philosophy dissertation. I am not attempting to build upon Abelard’s ideas but to clarify them. This is not to say that building upon Abelard’s ideas is not a worthwhile project. It is merely to say that doing …

Targeting Pten For Therapy In Cancer And Ptenopathies, Emily Palumbo

USF Tampa Graduate Theses and Dissertations

PTEN, a dual protein and lipid phosphatase, regulates a myriad of cellular functions including PI3K pathway signaling, cell migration, proliferation, invasion and apoptosis. PTEN mutations often lead to multiple malignancies, including prostate, breast, endometrial, skin and brain cancers, associated with hyperactive PI3K signaling. PTEN mutations have also been associated with a variety of other diseases, classified as PTEN Hamartoma Tumor Syndromes (PHTS). In addition, compromised function or reduced expression of PTEN due to non-genomic mechanisms are associated with many types of hyperproliferative diseases, such as restenosis and neoplastic diseases, including melanoma, lung, breast, prostate and colon cancers. Although PI3K pathway …

Optimizing Early Intervention For Preschoolers' Vocabulary Development, Lindsey A. Peters-Sanders

USF Tampa Graduate Theses and Dissertations

Preschool is a critical time in children’s oral language and pre-literacy skill development, but this development varies greatly among children. Those with smaller vocabularies are at greater risk for developing future language and reading difficulties that persist throughout their education. Because vocabulary knowledge is essential for later reading success, early instruction in preschool is key. To better understand how to enhance preschoolers’ word learning, the current dissertation contains three studies that examined the benefits of explicit vocabulary instruction and identified the factors that best facilitated vocabulary learning among a diverse group of young children. To aid in the early identification …

Variations Of Global Ocean Salinity From Multiple Gridded Argo Products, Chao Liu

USF Tampa Graduate Theses and Dissertations

Salinity is one of the fundamental ocean state variables. Variations of ocean salinity can be used to infer changes in the global water cycle and air-sea freshwater exchange. Many institutions have developed gridded Argo products of global coverage. However, the existing gridded salinity products have not yet been dedicatedly intercompare and assessed. In this study, the mean state, annual and interannual variabilities, and decadal changes of ocean salinity from five Argo-based gridded salinity products, available from UK Met Office, JAMSTEC, Scripps Institution of Oceanography, China Second Institute of Oceanography, and International Pacific Research Center, are examined and compared for their …

Statistical Learning Of Biomedical Non-Stationary Signals And Quality Of Life Modeling, Mahdi Goudarzi

USF Tampa Graduate Theses and Dissertations

Statistical learning is a set of tools for modeling and understanding complex datasets. It is a recently developed area in statistics and blends with parallel developments in computer science and, in particular, machine learning.

The classification of biomedical non-stationary signals such as Electroencephalogram (EEG) is always a challenging problem due to their complexity. The low spatial resolution on the scalp, curse of dimensionality, poor signal-to-noise ratio are disadvantages of working with biomedical signals. EEG signals are unstructured data which needs preprocessing steps to extract informative features which are measurable and predictive. In the first two chapters of this dissertation, EEG …

Simulation And Software Development To Understand Interactions Of Guest Molecules Inporous Materials, Douglas M. Franz

USF Tampa Graduate Theses and Dissertations

The effect of inclusion of explicit polarization is investigated through several theoret- ical studies of crystalline porous materials herein. In addition to the use of Monte Carlo simulation for such studies, a robust molecular dynamics software is presented which is suitable for analyzing time dependent properties of gases or other molecules in porous materials and other condensed phase systems. Metal-organic frameworks (MOFs) are the main focus of the work included here, a relatively young class of materials originally in- troduced in the early 1990s. These are usually three dimensional crystalline nanoporous materials that exhibit unique properties such as gas separation, …

A Multi-Dimensional Macrolevel Study Of Drug Enforcement Strategies, Heroin Prices, And Heroin Consumption Rates, Alexander G. Toth

USF Tampa Graduate Theses and Dissertations

American policy makers primarily embrace a deterrent-based policing agenda to curb illicit drug trafficking and use that relies on the principles of the economic price elasticity of demand (Boynum & Reuter, 2005). This counter-drug platform includes three fundamental programs: arresting offenders, seizing illicit drugs, and eradicating horticultural sources of illicit drugs (U.S. DEA, 2015). One of the main goals of these programs is to deter illegal trafficking and use by increasing the price of illicit substances so they are no longer attractive to consumers. The United States has weathered various drug use epidemics during its history, and currently it is …

Home-Based Cognitive Monitoring: The Role Of Personality And Predictors Of Adherence And Satisfaction, Nasreen A. Sadeq

USF Tampa Graduate Theses and Dissertations

Over the last several decades, a growing awareness of the benefits of regular screening for common health conditions, such as cancer and cardiovascular diseases, has paved the way for preventative screenings to become routine in medical settings. Given that cognitive impairment is frequently reported as the number one worry of older adults, home-based cognitive monitoring may be an innovative solution that allows middle aged and older adults to take an active role in monitoring an important aspect of their health. Although several home-based cognitive monitoring programs have been validated for use in clinical and home-based settings, the Cogstate Brief Battery …

Effects Of Support Fluid Type On Concrete Integrity And Durability In Drilled Shafts, Sarah J. Mobley

USF Tampa Graduate Theses and Dissertations

Until recently, concrete flow in tremie-placed drilled shafts has been mischaracterized as rising uniformly with laitance formation occurring only at the top of the rising concrete in the shaft. In actuality, concrete first fills a portion of the reinforcement cage to a sufficient height to promote radial flow into the cover region. Depending on support fluid type, the radial flow can produce laitance-filled creases/channels projecting the reinforcing cage configuration to the side of shaft surface. The flow pattern (and creases) can affect filter cake thickness, cover quality and propensity for corrosion. This research examines 52 tremie-placed laboratory drilled shaft specimens …

No One Wants To Read What You Write: A Contextualized Analysis Of Service Course Assignments, Tanya P. Zarlengo

USF Tampa Graduate Theses and Dissertations

This dissertation takes a systematic approach to answering the question of what services course assignment should accomplish in curricula by looking at the assignment from a contextual perspective that takes into consideration the programmatic factors in which the assignment circulates. The dissertation accomplishes this work by studying curricular artifacts, to include course syllabi and assignment descriptions, as well as textbooks. Additionally, interviews with program administrators and textbook authors are analyzed. The results of this analysis posit a programmatic network that visualizes connections between program, course, and staffing administrative factors with assignments as the nexus of the network. This dissertation illustrates …

Clinging In Plethodontid Salamanders, Mary Kathleen O'Donnell

USF Tampa Graduate Theses and Dissertations

The ability to cling to and climb on inclined, vertical, and inverted surfaces gives animals access to additional shelter and food and may provide refuge from unsuitable temperature and moisture conditions or escape from ground-dwelling predators. Salamanders have been shown to cling to surfaces and engage in climbing behavior, but their maximum clinging capability and mechanisms of attachment are not well understood. While some arboreal salamanders possess prehensile tails, salamanders lack many morphological adaptations for attachment, such as claws, toe pads, and fibrillar adhesive pads. Maximum cling performance and surface area of attachment were measured, and the adhesive capability of …

[X]Splaininggender, Race, Class, And Body: Metapragmatic Disputes Of Linguistic Authority And Ideologies On Twitter, Reddit, And Tumblr, Judith C. Bridges

USF Tampa Graduate Theses and Dissertations

This study investigates the language of “citizen sociolinguists,” everyday users of social network sites (SNS) who contribute to the discourses about language on Twitter, Reddit, and Tumblr, platforms with distinctive user demographics and technological affordances. The data were collected through keyword searches for mansplain, whitesplain, richsplain and thinsplain, metapragmatic neologisms which are lexical blends of the verb explain and one of four social categories. Disputes of macro-level ideologies are revealed by users’ creative meaning-making strategies and metapragmatic awareness of micro-level texts and utterances. Making use of the linguistic practices of the SNS, as well as the concisely-compacted semantic and pragmatic …

An Evaluation Of The Effects Of A Student Trajectory Enhancement Program (Step Up) On High School Performance, Odalys G. Pritchard

USF Tampa Graduate Theses and Dissertations

The Student Trajectory Enhancement Program (STEP UP) was launched in 2014 by Hillsborough County Public Schools (HCPS) as a six-week summer program that targeted over-age, retained, potentially under-achieving students completing the sixth grade. The purpose of this study was to conduct a summative evaluation of the effectiveness of the STEP UP program in keeping program participants “on track” for high school graduation and to determine if the intended goals of the program were realized.

STEP UP was developed in response to compelling data that there is an unacceptably high number of overage students in middle school in HCPS. STEP UP …

A Machine Learning Approach To Predicting Community Engagement On Social Media During Disasters, Adel Alshehri

USF Tampa Graduate Theses and Dissertations

The use of social media is expanding significantly and can serve a variety of purposes. Over the last few years, users of social media have played an increasing role in the dissemination of emergency and disaster information. It is becoming more common for affected populations and other stakeholders to turn to Twitter to gather information about a crisis when decisions need to be made, and action is taken. However, social media platforms, especially on Twitter, presents some drawbacks when it comes to gathering information during disasters. These drawbacks include information overload, messages are written in an informal format, the presence …

Linking Trait-Based Influences With Proximal, Contextually Driven Processes To Understand The Relationship Between Alcohol Use And Risk Behavior, Patrick M. Logan

USF Tampa Graduate Theses and Dissertations

Impulsivity-related traits explain a significant and meaningful level of variance in the prediction of drinking behavior. Previous research has demonstrated that although risk taking propensity has been conceptualized as a "trait-like" construct, there are contextual and situational factors that affect an individual's likelihood of engaging in risk taking behavior, including drinking behavior. Despite the well-established relationship between alcohol use and risk behavior (e.g., risky sexual behavior, physical assault, etc.), it is unclear how alcohol-related context influences risk taking on a computerized behavioral task. Grounded in alcohol expectancy theory (which holds that information processing about the rewarding effects of alcohol mediates …

Linking Sleep And Aggression: The Role Of Response Inhibition And Emotional Processing, Melanie L. Bozzay

USF Tampa Graduate Theses and Dissertations

Although shorter sleep duration is theorized to increase the risk of engaging in aggressive behavior, experimental studies examining this relationship yield conflicting findings. Since sleep serves in part to regulate the functioning of prefrontal brain regions, insufficient sleep may deleteriously impact the individual’s ability to inhibit rash action and alter emotional processing, which could in turn increase aggressive tendencies. However, no studies have examined the extent to which naturally occurring insufficient sleep is linked to aggression or potential mechanisms of this relationship, limiting understanding of and the generalizability of extant findings. Thus, the present study examined whether cognitive (deficits in …

Beyond Labels And Captions: Contextualizing Grounded Semantics For Explainable Visual Interpretation, Sathyanarayanan Narasimhan Aakur

USF Tampa Graduate Theses and Dissertations

One of the long-standing problems in artificial intelligence is the development of intelligent agents with complete visual understanding. Understanding entails recognition of scene attributes such as actors, objects and actions as well as reasoning about the common semantic structure that combines these attributes into a coherent description. While significant milestones have been achieved in the field of computer vision, majority of the work has been concentrated on supervised visual recognition where complex visual representations are learned and a few discrete categories or labels are assigned to these representations. This implies a closed world where the underlying assumption is that all …

The Role Of Social Media Journalists In Tv News:Their Effects On The Profession And Identity Of Tv Journalism, The Quality Of News, And Theaudience Engagement, Yousuf Humiad Al Yousufi

USF Tampa Graduate Theses and Dissertations

Spurred by the rapid influence of social media in the news industry, an increased number of TV news stations have started assigning dedicated social media journalists (SMJ) in newsrooms to monitor, gather, verify, share news, and engage with audiences on the streams of social media. Consequently, drawing on the diffusion of innovation theory, the present study probes into TV journalists’ perceptions of the implications of the role of this new type of TV professionals in the identity and profession of journalism, the quality of news pertaining to the verification of misinformation, and the news audiences’ attractions and viewership by capitalizing …

Plasticity In Animated Children’S Cartoons: The Neoliberal Transforming Bodies And Static Worlds Of Ok Ko And Gumball, Rachel E. Cox

USF Tampa Graduate Theses and Dissertations

Through the study of OK KO! Let’s Be Heroes! and The Amazing World of Gumball, I argue that children’s cartoons represent and recreate anxieties toward money’s plasticity in the plasticity of the cartoon bodies and worlds. I closely examine the ambivalence towards abstraction’s plasticity in contemporary children’s cartoons to trace the neoliberal ambivalence towards money’s plasticity. While much scholarship has grappled with what can be understood as animatic plasticity, very little of it takes on the questions raised about neoliberal culture by televised children’s cartoons. Cartoons are important to study in this respect because their form allows for unbridled plasticity. …

Reconstruction Of Radar Images By Using Spherical Mean And Regular Radon Transforms, Ozan Pirbudak

USF Tampa Graduate Theses and Dissertations

The goal of this study is the recovery of functions and finite parametric distributions from their spherical means over spheres and designing a general formula or algorithm for the reconstruction of a function f via its spherical mean transform. The theoretical study is and supported with a numerical implementation based on radar data. In this study, we approach the reconstruction problem in two different way. The first one is to show how the reconstruction problem could be converted to a Prony-type system of equations. After solving this Prony-type system of equations, one can extract the parameters that describe the corresponding …

Iron-Virus Interactions: Development And Testing Of The Ferrojan Horse Hypothesis, Chelsea Bonnain

USF Tampa Graduate Theses and Dissertations

Iron is an essential micronutrient for phytoplankton metabolism that limits growth in many regions of the surface ocean. More than 99.9% of oceanic dissolved iron is organically complexed to an iron-binding ligand, many of which have yet to be characterized. This thesis puts forth the Ferrojan Horse Hypothesis, which predicts a role for marine phages in oceanic iron cycling. Based on evidence from non-marine model systems, the Ferrojan Horse Hypothesis suggests that some marine phages (short for bacteriophages, or viruses that infect bacteria) can use iron as a “Trojan Horse” to gain access to host siderophore-bound iron receptors for infection. …

The Design Of Passive Networks With Full-Wave Component Models, Eric Valentino

USF Tampa Graduate Theses and Dissertations

In this thesis, the design of passive networks with the aid of full-wave simulation software and geometry-based models of lumped elements is investigated. This is done by examining the results of a number of simulation examples, as well as measured data from manufactured designs to compare against simulated equivalents. One such example is a chip antenna evaluation board design, in which the PCB, antenna, matching components and connector are all modeled. When measured, the simulation agreed with the board’s best matched frequency of 5.5 GHz to within 20 MHz. In another, a new antenna layout is generated from an existing …

Bridging The Achievement Gap: Promoting Equity In Teachers' Use Of Behavior-Specific Praise With Self-Monitoring And Performance Feedback, Ashley E. Knochel

USF Tampa Graduate Theses and Dissertations

Disparities in academic and social outcomes for ethnically diverse students in educational settings has been identified in the literature as the achievement gap. This study examined the impact of teacher training interventions on establishing equity in teacher implementation of a common positive behavior classroom support strategy, behavior-specific praise in four elementary classrooms. Teacher self-monitoring and written performance feedback were used to facilitate teachers to improve classroom practices by establishing proportionate praise and discipline practices across racially diverse students. A multiple-baseline across participants design was used to evaluate the impact of self-monitoring and written performance feedback with and without equity-focused procedures …

Prompt Level: Examination Of Whether Preference And Effectiveness Correspond In Children With Asd, Stacy Pamphile

USF Tampa Graduate Theses and Dissertations

Individuals diagnosed with Autism Spectrum Disorder (ASD) may be taught novel skills using various prompting strategies. Some studies have compared effective prompting procedures for these learners. Results have shown that no single procedure has been effective for all learners. Instead, efficiency of each response prompt type varied across participants. Some research suggests that identifying an individual’s preference may help identify an effective treatment. However, it is unknown if response prompt preference corresponds with effectiveness. Thus, the purpose of the present study is to evaluate whether preference corresponds with the most effective response prompt in children with ASD.

Collaboration: Who, When, And Why To Work Together, Michelle S. Kaplan

USF Tampa Graduate Theses and Dissertations

This study looked at how individuals choose whom to work with when a task necessitates collaboration. Prior research done on collaborative environments as well as outcomes of collaboration suggests that who you collaborate with will depend on two primary factors: the individuals from which you have to choose and the circumstances surrounding the task. In the proposed study, these factors will be explored. This thesis identified the lack of literature on informal collaboration, addressing the gap in the literature regarding processes that individuals use when choosing collaborators. This research focused on the influencing factors of similarity and expertise involved in …
