The Effects Of A Gamified Curriculum On High-School Students, Joshua Kyle Bastean

Theses and Dissertations

One of the emerging trends in education is gamification, a concept that has been applied in other fields, such as business and advertising, with great success. Gamification can be defined as adding game elements to non-game constructs. This study followed a high-school Algebra II teacher and 10 of her students in an attempt to document the effects of gamification on student academic engagement. Multiple methods of data collection were used to gather data from students and teachers. After analysis, the data showed that gamification had a positive effect on student academic engagement. The results were used to create an action …

More Than Meets The Eye: Development Of A Sport Event Stimuli And Destination Image Fit Scale, Yongjin Hwang

Theses and Dissertations

Much research demonstrates an impact of sensory experience on sports fans’ satisfaction with live sporting events (Lee, Heere, & Chung, 2013; Lee, Lee, Seo, & Green, 2012). It was, however, not studied how to enhance those sense-centric experiences. One possible approach would be to utilize unique region-based characteristics to design unforgettable and emotionally engaging experiences. Most sporting events are location-based, and venues are also considered as a landmark of the area where they are placed. Consequently, we can create a natural link between sporting events and the hosting cities or regions. Visual designs, musical contents, famous local food, and signature …

Restoration Of Visual Performance And Opsin Expression Within The Retina During Eye Regeneration In The Florida Fighting Conch (Strombus Alatus), Jamie M. Clark

Theses and Dissertations

Conch are slow-moving, herbivorous, marine gastropods that possess prominent camera-type eyes at the ends of long, flexible stalks. Compared to the eyes of other gastropods, those of conch are large (up to 1.5 mm in diameter) and have sophisticated optics that include a lens with a graded refractive index. Conch also have a remarkable ability to regenerate eye tissue: after an eye is lost, a new eye will develop to take its place within weeks. Eye regeneration in conch appears to occur rapidly compared to eye regeneration in other gastropods. Despite our knowledge of the complexity and regenerative abilities of …

Chemotherapy Knowledge And Health Literacy Among Women With Breast Cancer, Pearman Detreville Parker

Theses and Dissertations

Chemotherapy education is imperative for patients to gain the knowledge to manage side effects, adhere to prescribed cycles, and recognize the severity of symptoms that require immediate provider contact. Two vital factors – the readability of teaching materials and the patient’s health literacy – must be considered during chemotherapy education. However, materials are often not assessed for readability. Further, the influence of a patient’s health literacy level and demographic factors on chemotherapy knowledge has not yet been investigated. The specific aims are to: (1) critique the readability and format of chemotherapy education materials; (2) explore how women with breast cancer …

With each tornado there is a tornado warning that the National Weather Service (NWS) issues with a goal of protecting life and property. By using social media, these messages quickly reach the public. By analyzing Twitter data, this study aims to gain a spatiotemporal understanding of tweets, including when and where they most frequently occur. Most tweets occur within the warning time (temporal) and inside the warning polygon (spatial). To gain a better understanding of the information the tweet contains, a content analysis shows key warning characteristics such as …

Efficient Design Optimization Methodology For Nonconventional Laminated Thin-Walled Composite Structures, Mazen Albazzan

Theses and Dissertations

Structural designers seek the best possible design of a structure that optimally meets the requirements of a specific application. The measure of the quality of the final design can often be related to specific stiffness and strength of the structure. Because of their superior mechanical and environmental properties compared to traditional metals, fiberreinforced composite materials have earned a widespread acceptance for different structural applications. The tailoring potential of composites to achieve high specific stiffness and strength has promoted them as promising candidates for constructing lightweight structures. From that aspect, designers have tackled the problem of designing composite laminates, which is …

Multiscale Deformation And Failure Behavior Of Polymer Bonded Explosives Subjected To High Rate Loading, Suraj Muthiramalil Ravindran

Theses and Dissertations

Polymer bonded explosives (PBX) are heterogeneous granular composites with a high-volume fraction of solid. Typically, they contain 80-95% explosive crystals and 5- 20% soft polymer binder. These materials are subjected to different loading conditions during their service life. The main function of the soft binder is to reduce shock sensitivity to prevent an accidental explosion. However, there have been inadvertent detonations in these materials during transportation and handling. The reason for such unintentional explosion is not well understood. It is commonly accepted that the formation of local hightemperature regions, called ‘hot spots’, is the primary cause. Hotspot formation is associated …

Changes Of Dispersal Ability In An Isolated Population, Connor Bacon

Theses and Dissertations

Dispersal is a core mechanism in the maintenance of metapopulations. It maintains genetic diversity by connecting subpopulations and generates new populations to replace those that die out. However, as populations become more isolated, as occurs in habitat fragmentation, dispersal becomes more difficult. This should lead to selective pressure against dispersive individuals, causing a reduction in dispersal traits. Over time, this can lead to variation in dispersal traits among populations. We examine this idea using an extreme case of isolation in Euphydryas gillettii, a population that has remained completely isolated for forty years. By comparing this population to a baseline established …

Semiparametric Regression In The Presence Of Measurement Error, Xiang Li

Theses and Dissertations

The error-in-covariates problem has received great attention among researchers who study semiparametric and nonparametric inference for regression models over the past two decades. Without correcting for the measurement error in covariates, estimators for covariate effect usually contain bias. To account for measurement error, much research have been done in mean regression (Liang et al., 1999; Fuller, 2009; Carroll et al., 2006) and quantile regression (He and Liang, 2000; Hardle et al., 2000; Wei and Carroll, 2009). In contrast, there is little research in mode regression and this motivates us to propose semiparametric methods to address this error-incovariates problem in Chapters …

Theses and Dissertations

The World Health Organization (WHO) defines health system as comprising of all the organizations, resources, and institutions dedicated to improving health. Health systems have a responsibility not just to improve the health of the population they serve but to provide financial protection against the costs of illness and to respond to people’s expectation with dignity. Besides, healthcare satisfaction and consumer satisfaction have become the latest trend in measuring quality to have a competitive advantage or best practice in the healthcare industry. Over the past 30 years, consumer satisfaction has gained widespread recognition as a measure of quality in many services …

East Branch Of The Cooper River, 1780-1820: Panopticism And Mobility, Lisa Briggitte Randle

Theses and Dissertations

In recent years historical archaeologists have employed the panoptic plantation approach to examine issues of surveillance and control at plantations. Despite new scholarship in the area of the panoptic plantation, few studies place the enslaved laborer at the center and the planter-elite on the periphery. Failure to broaden the scope of studies that focus on enslaved laborers minimizes the importance of the differences in perception, cognition, and landscape between the planter-elite and the enslaved laborers. The aim of this study is to determine potential enslaved laborer mobility and how cognitive predictive models can aid in identifying potential locations for archaeological …

Economic Feasibility And Social Consideration For Jamaica Expanding Its Renewable Portfolio Mix Upon A Microgrid System, Caliphor Jameel Fagan

Theses and Dissertations

According to Lund (2007), energy sources can be divided into three main categories: fossil fuels, nuclear resources, and renewable energy sources. Renewable energy technologies are on the upward trend both residentially and commercially, with many studies being conducted to optimize its use. There are many opportunities that exists for Jamaica to utilize renewable sources as energy for generating electricity. Several sources, including the Ministry of Science, Technology, Energy, and Mining of Jamaica, states that the country sources just over 90 percent (90%) of its electricity capacity from petroleum-based power plants. Along with a high petroleum fuel source power-generation, the method …

An Axion Search With The Majorana Demonstrator, Clinton Gray Wiseman

Theses and Dissertations

The Majorana Demonstrator is an array of P-type point contact (PPC) germanium detectors enclosed in a multi-layered shield at the 4850’ level of the Sanford Underground Research Facility. Its primary goal is to search for the neutrinoless double beta decay of 76Ge. The initial 10 kg-y dataset, taken over a two year period, has energy thresholds as low as 1 keV. This allows concurrent rare event searches for the signatures of dark matter and solar axions in the low energy spectrum. Though the detectors are routinely operated with sub-keV energy thresholds, changing noise conditions in the array have made it …

From Rhetoric To Response: Climate Change, Conflict, And Development In Karamoja, Uganda, Daniel Abrahams

Theses and Dissertations

This dissertation addresses the broad question: How do the discourses of climate change and conflict travel across time and space to become policy, programming, and ultimately a development initiative that exist on the ground? To answer this question, I broke the research into three separate papers. The first examines how the US policy community approaches, understands and seeks to address the discourses of climatesecurity. The second examines the ways in which climate change affects conflict outcomes in Karamoja, Uganda. And the third, using the efforts of Mercy Corps in Karamoja as a case study, examines the realities and opportunities in …

Historical Inquiry And Student Perceptions Of Cultural Groups In A Social Studies Classroom, Michelle Pope

Theses and Dissertations

This dissertation addresses a problem of practice stemming from the accountability movement and its emphasis on high-stakes testing in the social studies classroom. An examination of the problem of practice led to the research question: How does the use of the scientifically based method of historical inquiry affect student perceptions of cultures other than their own? The purpose of this action research study was to examine the use of historical inquiry as a means of combating the lack of depth in a formal curriculum focused on high-stakes testing and a hidden curriculum that promotes a “top-down,” Eurocentric approach to history …

From Seeds To Shoreline®: A Place-Based Approach To Impacting Student Engagement And Achievement, Molly Lloyd

Theses and Dissertations

Place-based education refers to pedagogy that connects student learning with the local environment and students’ lives. Educators’ preoccupation with standardized test scores have increased the disconnect between formal education and student’s life experiences. Schools have developed systems of learning in isolated subjects through reading texts, listening to lectures, or watching videos rather than authentic, experiential learning. School districts have embraced a STEM (science, technology, engineering, and science) approach to education as a way of invigorating student learning. There are many approaches to integrating, hands-on, inquiry-based science lessons. As science PASS test scores have declined, educators are examining best STEM instructional …

Inorganic Nanocrystals And Their Applications In Hybrid 0d:2d Material Optoelectronics, Mathew Kelley

Theses and Dissertations

Functional nanomaterials have garnered great interest as candidates for use in next-generational optoelectronics such as solar photovoltaics, light-emitting diodes, and photodetectors. Among these low-dimensional materials, hybrid devices employing both 0D and 2D materials are of interest due to exploitation of the favorable characteristics of each component, and performances superior to standalone counterparts are achievable. This thesis is divided into two parts, as follows. The first two chapters will introduce lowdimensional materials and their favorable characteristics; our work on the formation of ligand-exchanged nanocrystal thin films purified by gel-permeation chromatography will also be discussed. In the second component, the formation and …

After the pretest, three students were selected, from under-represented groups, for in-depth observation, interviews, and collection of artifacts in order to determine the impact of problem-solving techniques. The work of these students, from underrepresented groups, was examined to gain insight into their experiences and thought processes surrounding problem-solving. The students answered questions about their attitude towards …

An Investigation Of Brain Normalization And Lesion Compensation Techniques Applied To Stroke, Taylor Hanayik

Theses and Dissertations

One of the most ubiquitous steps in neuroimaging is the normalization of brain images. The process of normalization attempts to match any given brain to a standardized template image (e.g. the MNI 152 image). However, clinical images such as those from stroke participants present many challenges when we attempt to warp them to the space of template images, which are typically representative of neurologically healthy individuals. Many software packages exist to facilitate normalization of brain images, but most have limited options available to compensate for brain injury, which is often disruptive to these algorithms. Of the injury compensation methods that …

Deepening Democracy: Inclusion, Deliberation, And Voice In The Grassroots South, Annie L. Boiter-Jolley

Theses and Dissertations

Through an exploration of grassroots challenges to shallow democracy in South Carolina, this dissertation offers a model of democratization based on inclusion, deliberation, and empowerment as a remedy for democratic insufficiency. I posit that greater emphasis on inclusive democratic deliberation, both inside and outside formal political structures, will help deepen the South’s shallow democracy, and that inclusive deliberation fostered through grassroots organizing that priorities consciousness raising, empowerment, and activism training will positively affect participants, deliberation, and policy outcomes. Taking a grounded theory approach, I consider case studies of three organizations based in Columbia, South Carolina, and their attending theories of …

Phylogeny, Ancestral Genome, And Disease Diagnoses Models Constructions Using Biological Data, Bing Feng

Theses and Dissertations

Studies of bioinformatics develop methods and software tools to analyze the biological data and provide insight of the mechanisms of biological process. Machine learning techniques have been widely used by researchers for disease prediction, disease diagnosis, and bio-marker identification. Using machine-learning algorithms to diagnose diseases has a couple of advantages. Besides solely relying on the doctors’ experiences and stereotyped formulas, researchers could use learning algorithms to analyze sophisticated, high-dimensional and multimodal biomedical data, and construct prediction/classification models to make decisions even when some information was incomplete, unknown, or contradictory. In this study, first of all, we built an automated computational …

Integrating Genetic Counseling And Testing In The Pediatric Oncology Setting: Parental Attitudes And Influencing Factors, Lauren Renee Desrosiers

Theses and Dissertations

Cancer predisposition syndromes (CPS), caused by germline pathogenic variants in tumor suppressor genes and oncogenes, are genetic conditions that put an individual at increased risk to develop cancer. It is estimated that 10-15% of children with cancer have an underlying CPS. Although genetic testing for these conditions has become routine in the adult setting, incorporation of germline genomic technologies into pediatric cancer care has not occurred as rapidly. The purpose of this study is to assess desire for genetic counseling and testing services among parents of children with cancer to provide parental insight in the incorporation of genomic technologies in …

Aporetic Rhetoric: The Use Of Uncertainty In Healthcare Contexts, Adam S. Lerner

Theses and Dissertations

This project examines how uncertainty is rhetorically deployed in healthcare contexts. Investigating four major healthcare contexts, I study how different forms of uncertainty produce distinct rhetorical effects and consequences. In Chapter 1, I explore how the haphazard use of Agent Orange during the Vietnam war makes it difficult for veterans to prove their exposure to this deadly chemical. In Chapter 2, I examine the rhetorical strategies of mental illness skeptics and denialists, looking at how each deploys uncertainty in different and related ways. In Chapter 3, I investigate the intersection between design, emotion, and uncertainty as it appears in the …
