Teacher-Implemented Presession Pairing To Improve Classroom Behaviors In Public Schools, Rachel M. Sofarelli

USF Tampa Graduate Theses and Dissertations

Presession pairing is an antecedent intervention that has shown to decrease problem behavior of elementary school children with autism, whose problem behavior is maintained by social reinforcement. It has also shown modest increases in academic responding. However, the research on presession pairing has not examined its efficacy or acceptability in the natural classroom setting when implemented by the teacher. Therefore, this study used teacher training and a multiple baseline across participants design to test the potential efficacy of teacher-implemented presession pairing in increasing on-task behavior and reducing problem behavior of four students with problem behavior in inclusive public elementary school …

Three Essays On Digital Annual Reports For Nonprofessional Investors: The Impacts Of Presentation Formats On Investment-Related Judgments And Decisions, Yibo Zhang (James)

USF Tampa Graduate Theses and Dissertations

The goal of this dissertation is to investigate the impact of presentation formats on nonprofessional investors’ impressions of firm performance in the context of digital annual reports. The dissertation implements a three-essay approach.

Essay 1 examines whether the effect of positive/negative financial performance news on nonprofessional investors’ impressions of management and firm performance depends on whether the graphical display of that news is vivid or pallid. Conducting a 2 x 2 between-participants experiment with 470 participants from Amazon Mechanical Turk (M-Turk), I find that when the news is positive, presenting graphs vividly allows nonprofessional investors to have a more positive …

Incorporating Auditory And Visual Feedback And Student Choice Into An Interdependent Group Contingency To Improve On-Task Behavior, Beth Giguere

USF Tampa Graduate Theses and Dissertations

Group contingencies are efficient and effective behavioral interventions that allow teachers to apply a reinforcement criterion to a large group of students. However, most research on group contingencies has not examined the impact of types of teacher feedback and student choice of teacher feedback incorporated into the use of group contingencies. The current study used a multiple baseline across participants design with an embedded alternating treatments design to explore the use of an interdependent group contingency that compared the effectiveness of incorporating auditory or visual feedback to improve student on-task behavior of three students in public elementary school classrooms.

Quantifying The Effect Of Topographic Slope On Lava Flow Thickness: A First Step To Improve Lava Flow Volume Estimation Methods, Steven R. Rizo

USF Tampa Graduate Theses and Dissertations

The volume of lava flows provide important information on the magnitude of volcanic eruptions, and accurate volumes are necessary to produce reliable models of lava flow emplacement or constrain the internal structure of volcanoes. The most accurate lava flow volumes are obtainable when the topography before and after an eruption are both known, but information for the topography before lava flow emplacement is absent in non-historic lava flows. To calculate the volume of non-historic lava flows, this pre-emplacement topography needs to be reconstructed. Common methods for this include using inverse distance-weighted averages or global polynomial interpolation methods, but these can …

Reproducing Intersex Trouble: An Analysis Of The M.C. Case In The Media, Jamie M. Lane

USF Tampa Graduate Theses and Dissertations

How do members of the media represent intersex people? Do the voices of intersex activists find their way into mainstream media representations, or are they ignored? What types of discourses are produced by the presence (or lack thereof) of activist voices in news articles? The goal of this thesis is to interrogate the discourse surrounding intersex, or individuals who fall outside of the typical male/female binary for sex classification, and intersex activism in the media. The legal case M.C. vs. Aaronson, settled in 2017, was one of the first legal cases in the United States involving an intersex person. This …

A Point Cloud Approach To Object Slicing For 3d Printing, William Edward Oropallo Jr.

USF Tampa Graduate Theses and Dissertations

Various industries have embraced 3D printing for manufacturing on-demand, custom printed parts. However, 3D printing requires intelligent data processing and algorithms to go from CAD model to machine instructions. One of the most crucial steps in the process is the slicing of the object. Most 3D printers build parts by accumulating material layers by layer. 3D printing software needs to calculate these layers for manufacturing by slicing a model and calculating the intersections. Finding exact solutions of intersections on the original model is mathematically complicated and computationally demanding. A preprocessing stage of tessellation has become the standard practice for slicing …

Penalizing Pregnancy: A Feminist Legal Studies Analysis Of Purvi Patel's Criminalization, Abby Schneller

USF Tampa Graduate Theses and Dissertations

Purvi Patel is an Indian American woman who, in 2015, was the first U.S. citizen to be convicted under feticide statutes for allegedly attempting her own abortion. Though her 2015 conviction was overturned the same year, the feticide conviction was significant as a legal precedent as well as part of a larger trend criminalizing pregnant women of color. With an eye towards the greater pattern of the criminalization of other pregnant women of color (Boyd, 1999; Faludi, 1991; Humphries, 1999; Mahan, 1996; Roberts, 1997), in this thesis I employ a feminist legal studies methodology and the theoretical frameworks of intersectionality …

The purpose of this study was to investigate empirically the political talk show phenomenon in Taiwan. Specifically, the study examined the perceived influence of political talk shows on the Taiwanese audience themselves (first-person effect) and others (third-person effect), the attitudinal antecedents of the perceived influences, and attitude toward restrictions on political talk shows. Data were collected from a convenient sample of 1053 adult Taiwanese citizens via an online survey. The results supported the hypothesized relationships between attitude toward political talk shows and perceived influence of the shows on self and others. Results also supported the looking glass perception hypothesis whereby …

Failing To Move Forward: Journalism, Media, And Affect In David Fincher's, Nicholas Orlando

USF Tampa Graduate Theses and Dissertations

Zodiac (David Fincher, 2007) offers a critique of the mass media’s efforts to restore American valiance with heroic narratives of ordinary people in the aftermath of 9/11. Amending prior scholarly readings of Zodiac as a serial killer narrative, I reconfigure my analysis by taking Fincher at his word and treating it as a journalism film. Borrowing a term from political theorist Elisabeth Anker, I argue that, unlike other contemporary journalism films, Zodiac is constructed as a “melodrama of failure” that, rather than seeking mastery, unveils the instability of evidence and the obsessive uncertainty of procedure.

With his film sitting between …

Visualizing Load Path In Perforated Shear Walls, Ying Chih Chen

USF Tampa Graduate Theses and Dissertations

Shear walls are the primary lateral load resisting elements in bearing wall systems used in masonry construction. Horizontal loads due to wind or earthquake are transferred to vertical walls by diaphragms that are rigid such as concrete floor slabs or flexible such as wood floors. With rigid diaphragms, loads are apportioned to the supporting walls based on their relative rigidity. Walls with openings accommodating doors and windows (“perforated walls”) have reduced rigidity that can be determined using available hand calculation methods. These methods primarily focus on analysis procedures, not on the visualization of the load path that is critically important …

Once Upon A Genre: Distant Reading, The Newbery Medal, And The Affordances Of Interdisciplinary Paradigms For Understanding Children’S Literature, Melanie Griffin

USF Tampa Graduate Theses and Dissertations

Typical critical patterns for studying children’s literature, defined in this study as a written text intended for a reader up to the age of 14, make it difficult to chart generic change across a large corpus of texts. Traditionally, criticism of children’s literature focuses on cherry picked archetypes, exemplars, and the standout extraordinary. This study employs interdisciplinary methods and data sources from library science, education, and literary studies to create a method for analyzing a sample corpus of children’s literature more holistically vis-à-vis distant, macroscopic reading techniques.

In this dissertation, I macroscopically read the corpus of Newbery Medal-winning texts in …

USF Tampa Graduate Theses and Dissertations

Global rankings are a popular way for governments, HEI’s, faculty, staff, and students to compare institutions worldwide, therefore it is important to rank well. However, in order to have top-quality research and education programs, HEI’s need to have significant financial resources. The purpose of this study was to explore the relationship between an institution’s financial resources and its global ranking. The results of this study provide additional insight and a better understanding of global rankings and the nature of the relationship between various financial resources and global rankings.

This was a quantitative study that used ranking data from the Academic …

The Promised Body: Diet Culture, The Fat Subject, And Ambivalence As Resistance, Jennifer Dolan

USF Tampa Graduate Theses and Dissertations

Since the turn of the twentieth century, middle-class Americans have considered the thin body--ostensibly the result of self-control and self-discipline--a moral imperative and a symbol of good citizenship. In this thesis, I provide a critical perspective on fat studies by examining the ways in which the field authorizes itself in a society that deems the fat body unhealthy, costly, and immoral. As one potential solution to fat-hatred, fat studies proposes fat-positivity, but I argue that fat-positivity requires an extraordinary act of imagination in which the fat person overcomes what I term the ideology of thinness and subsequently feels good about …

Supported Perovskite-Type Oxides: Establishing A Foundation For Co2 Conversion Through Reverse Water-Gas Shift Chemical Looping, Bryan J. Hare

USF Tampa Graduate Theses and Dissertations

Perovskite-type oxides show irrefutable potential for feasible thermochemical solar-driven CO₂ conversion. These materials exhibit the exact characteristics required by the low temperature reverse water-gas shift chemical looping process. These properties include structural endurance and high oxygen redox capacity, which results in the formation of numerous oxygen vacancies, or active sites for CO₂ conversion. A major drawback is the decrease in oxygen self-diffusion with increasing perovskite particle size. In this study, the La_0.75Sr_0.25FeO₃ (LSF) perovskite oxide was combined with various supports including popular redox materials CeO₂ and ZrO₂ along with more abundant …

Adult College Students' Perceptions About Learning Mathematics Via Developmental Mathematical Xmoocs, Pelagia Alesafis Kilgore

USF Tampa Graduate Theses and Dissertations

Debates over the promising change Massive Open Online Courses (MOOCs) might offer to traditional online learning now produce significant attention and discourse among the media and higher education. Ample articles discuss the potential benefits of MOOCs from the perspectives of faculty and administration. However, little is known about students’ perceptions of MOOCs. Given the lack of relevant literature and the reality that MOOCs are created to benefit students, it is important to elicit current college students’ perceptions of MOOCs since it is well documented learning mathematics online has its problems (Ashby, Sadera, & McNary, 2011; Frame, 2012; Ho et al., …

Angiostrongylus Cantonensis: Epidemiologic Review, Location-Specific Habitat Modelling, And Surveillance In Hillsborough County, Florida, U.S.A., Brad Christian Perich

USF Tampa Graduate Theses and Dissertations

Angiostrongylus cantonensis is a parasitic nematode endemic to tropical and subtropical regions and is the leading cause of human eosinophilic meningitis. The parasite is commonly known as rat lungworm because the primary host in its lifecycle is the rat. A clinical overview of rat lungworm infection is presented, followed by a literature review of rat lungworm epidemiology, risk factors, and surveillance projects. Data collected from previous snail surveys in Florida was considered alongside elevation, population per square kilometer, median household income by zip code territory, and normalized difference vegetation index specific to the geographic coordinates from which the snail samples …

Strategies To Adjust For Response Bias In Clinical Trials: A Simulation Study, Victoria R. Swaidan

USF Tampa Graduate Theses and Dissertations

Background: Response bias can distort treatment effect estimates and inferences in clinical trials. Although prevention, quantification, and adjustments have been developed, current methods are not applicable when subject-level reliability is used as the measure of response bias. Thus, the objective of the current study is to develop, test, and recommend a series of bias correction strategies for use in these cases. Methods: Monte Carlo simulation and logistic regression modeling were used to develop the strategies, examining the collective impact of sample size (N), effect size (ES), reliability distribution, and response style on estimating the treatment effect size in a series …

"Ain't I A Woman?": Black Women Negotiate And Resist Systemic Oppression In Undergraduate Engineering And Mathematics Disciplines, Jessica Alyce Wilson

USF Tampa Graduate Theses and Dissertations

In this inquiry I used Black Feminist Thought as the interpretive lens to investigate the characterizations and experiences of high achieving Black women undergraduate engineering and mathematics majors at a predominantly white institution. The qualitative inquiry considered intersecting oppressions to evaluate the experiences of this population. In particular, Black women operate in the intersection of race and gender, thus for a thorough analysis of their engineering and mathematics experiences to occur, the historical context of the United States and its oppressive structures must be considered. Stereotypes and systemic oppression follow this socially constructed identity as the participants enter the fields …

Missing Data In Complex Sample Surveys: Impact Of Deletion And Imputation Treatments On Point And Interval Parameter Estimates, Anh Pham Kellermann

USF Tampa Graduate Theses and Dissertations

The purpose of this simulation study was to evaluate the relative performance of five missing data treatments (MDTs) for handling missing data in complex sample surveys. The five missing data methods included in this study were listwise deletion (LW), single hot-deck imputation (HS), single regression imputation (RS), hot-deck-based multiple imputation (HM), and regression-based multiple imputation (RM). These MDTs were assessed in the context of regression weight estimates in multiple regression analysis in complex sample data with two data levels. In this study, the multiple regression equation had six regressors without missing data and two regressors with missing data. The four …

Assessing The Impacts Of Climate Change On Streamflow And Reservoir Operation In Central Florida, Toni Panaou

USF Tampa Graduate Theses and Dissertations

Climate change is a global concern as it may affect many aspects of life, including water supply. A tool used to model climate change’s impacts is called a General Circulation Model (GCM). GCMs project future scenarios including temperature and precipitation, but these are designed at a coarse resolution and require downscaling for employment for regional hydrologic modeling. There is a vast amount of research on downscaling and bias-correcting GCMs data, but it is unknown whether these techniques alter precipitation signals embedded in these models or reproduce climate states that are viable for water resource planning and management. Using the Tampa, …

Distinguishing Patterns Of Utopia And Dystopia, East And West, Huai-Hsuan Huang

USF Tampa Graduate Theses and Dissertations

Before Sir Thomas More published Utopia and defined his ideal world with this fictional land, humans had been looking for their ideal society for centuries based on various religions and cultures. Yet, there are a few studies focusing on Utopia and Dystopia in cross-cultural contexts. This thesis will explore the two main questions: 1) can Utopia and Dystopia be separated? and 2) how does the utopian concept in the West involve in Eastern culture during the postwar period in postcolonial perspective?

Phoenix in Japan and THX 1138 in U.S. are two well-known works during the post-World War II period via …

Perceptual And Physiologic Analysis Of Dystussia In Amyotrophic Lateral Sclerosis, Stephanie Anne Watts

USF Tampa Graduate Theses and Dissertations

Swallowing and cough are two vital functions that are reflexive in nature and are related to each other in terms of shared neural and anatomical space. When a disorder impacts normal and effective swallowing and/or cough, the consequences can be life-threatening. Evaluation and treatment of swallowing and cough disorders can fall under the scope of practice of the speech-language pathologist and speech-language pathologists often are leading professionals. Furthermore, much of the current research on swallowing and cough is spearheaded by speech-language pathologists often working with a multi-disciplinary team. The focus of this dissertation is on the clinical evaluation of cough …

“I Use To Pray And Ask God To Give Me Another Chance”: A Phenomenological Analysis Of Black Males’ Journey Attending An Alternative School, Jimmy R. Caldwell Jr

USF Tampa Graduate Theses and Dissertations

Research suggests that there still exists a disproportionate number of Black males who have contact with juvenile justice systems across this nation (Nance, 2016). The disproportionate placement of students of color, specifically, Black American males in alternative schools, serves as the gateway to the school-to-prison-pipeline (Pelzer, 2012). This study examined the lived educational experiences of two Black American juvenile males, who enrolled in an alternative school in the Southeast. This study incorporated phenomenological and narrative methods and provides rich, descriptive analyses of the participants’ experiences while attending an alternative school. Findings from this study revealed instability among the participants’ home …

A High Accuracy Microwave Radiometric Thermometer To Measure Internal Body Temperature, Michael D. Grady

USF Tampa Graduate Theses and Dissertations

The Center for Disease Control and Prevention (CDC) released heat illness data which highlighted that ~29 heat stress hospitalizations and ~3 heat-related deaths occurred every day during the summer months within the US from years 2000 to 2014. Heatstroke- the most severe form of heat illness which oftentimes lead to death- has been cited to be entirely preventable if a timely intervention is introduced. This dissertation uses microwave radiometric thermometry to perform wireless non-invasive internal body temperature monitoring which can enable intervention methods that help to prevent deaths associated with heat-illness.

Overall, this dissertation develops a comprehensive closed-form analytical radiometric …

Graph-Based Latent Embedding, Annotation And Representation Learning In Neural Networks For Semi-Supervised And Unsupervised Settings, Ismail Ozsel Kilinc

USF Tampa Graduate Theses and Dissertations

Machine learning has been immensely successful in supervised learning with outstanding examples in major industrial applications such as voice and image recognition. Following these developments, the most recent research has now begun to focus primarily on algorithms which can exploit very large sets of unlabeled examples to reduce the amount of manually labeled data required for existing models to perform well. In this dissertation, we propose graph-based latent embedding/annotation/representation learning techniques in neural networks tailored for semi-supervised and unsupervised learning problems. Specifically, we propose a novel regularization technique called Graph-based Activity Regularization (GAR) and a novel output layer modification called …
