Show moreExamining the education practices in early America provides a glimpse into the structure of colonial society as a whole. More specifically, the education system sheds light on how traditionally marginalized groups gained improved opportunities within society. This thesis examines the education of three key groups of people: women, Africans, and Native Americans. More specifically, this thesis traces the increase in educational opportunities made available to each of these groups in eighteenth-century Philadelphia. With the Quakers at the forefront, traditionally marginalized people began to receive improved educational opportunities. Writings from a Quaker central to education reform, Anthony Benezet, are examined in order to show how the Quakers in eighteenth-century Philadelphia created a unique system of educational inclusivity. Benezet was an early abolitionist and educator who played a significant role in the education of women and minorities in eighteenth-century Pennsylvania. Benezet and the Quakers reimagined education by providing quality educations to less-fortunate groups of people. Their work served as an example of how women and minorities were capable of high-level academic achievement.

Show moreIncorporating archaeology within the high school curricula fosters an interest in archaeology and site preservation. The Milton High School Archaeology Project provides students the opportunity to experience and participate in archaeological research. At a 19th-century brickyard, students learn anthropology and their local history through hands-on excavations. Through the use of Project-Based Learning (PBL), students conducted archaeological and historical research and presented their work in the form of a museum exhibit at the Florida Public Archaeological Network's Destination Archaeology Resources Center museum for the public and their parents. The Milton High School Archaeology Project provides an example of how archaeology can easily and effectively be integrated into high school educational standards. Quantitative and qualitative data collected throughout the 2016-2017 school year shows how archaeology education leads to increased awareness of and appreciation for heritage sites.

Show moreOnline higher education has expanded over the last decade to meet workforce needs for job placement in areas such as healthcare. Collaborative activities are a method used in higher education to develop the higher-order skills that students need to succeed in today's workforce. However, instructors have continued to make the integration of online collaborative activities a low priority. The purpose of this qualitative case study was to explore instructor intent to integrate collaborative activities in online undergraduate courses preparing students in the field of healthcare. Participants were a purposefully selected sample of 10 undergraduate instructors in healthcare who were not integrating online collaborative activities at the time of the study. The sources of data were one-on-one interviews, a focus group interview, and document research. The theory of planned behavior provided the framework to align the purpose of the study and the research questions. The theory of planned behavior assumes a person's intentions accurately predict a corresponding behavior, and the factors influencing their intent include personal attitude, subjective norms, and perceived behavioral control. The findings demonstrate that instructors had a negative intent to integrate online collaborative activities, and the primary areas of influence were personal attitude and subjective norms. Major conclusions include the fact that instructors believe collaborative activities do not achieve the intended outcomes and are more difficult for instructors to manage online than in face-to-face courses. Future research should explore whether strategies directed at changing these beliefs alter the intent to integrate online collaborative activities.

Show moreABSTRACT: Higher education institutions implement lecture capturing technology (LCT) to provide students access to recorded course lectures. Consequently, institutions can experience barriers implementing LCT related to lack of student use of the technology. This study's purpose was to examine whether performance expectancy, effort expectancy, social influence, and facilitating conditions influence undergraduate nursing students' decisions to use LCT after attending face-to-face lectures at a state college in Florida. The unified theory of acceptance and use of technology (UTAUT) served as the theoretical framework. This study incorporated a quantitative correlational design and used a modified UTAUT survey instrument to determine if there are statistically significant relationships among the UTAUT constructs and LCT use. A linear regression was performed, and the results suggested there was a statistically significant relationship between the performance expectancy construct and use of LCT, r(116) = .647, p < .01, two-tailed; the effort expectancy construct and use of LCT, r(116) = .249, p < .01, two tailed; and the social influence construct and student use of LCT, r(116) = .255, p < .01, two tailed. A multiple regression analysis suggested performance expectancy, effort expectancy, social influence, and facilitating conditions statistically significantly predicted student LCT usage, F(4, 113) = 21.32, p < .001. The R2 = .430 with a large effect size (f2 = .754). The results from this study add to the limited body of knowledge on LCT use and provide technology leaders with a better understanding of factors contributing to student use of LCT, which can be used for future research.

Show moreWith the rising threat of anthropogenic climate change, human pathogens Vibrio vulnificus (Vv) and parahaemolyticus (Vp) may become more problematic to world health. The aims of this study were to i) report baseline Vv and Vp abundances, ii) develop new oligonucleotide primer sets for detection of Vv and Vp pathogens, and iii) explore interactions with other waterborne nuisances. We sampled surface waters, sediments, and invertebrate biofilms from 43 locations in two estuarine systems over seven dates in winter 2020. Culturable Vv was present in most water and sediment samples, but Vp only in about half of the surface waters. Surface Vv covaried with bottom water pH and tidal coefficient. Vp surface concentrations correlated negatively with surface salinity, and positively with total surface nitrogen. Both species correlated with wind, suggesting resuspension was important. These regionally-novel winter baseline Vibrio abundances will aid in predicting risk factors in each waterbody of interest. In-house databases were constructed to design better primer pairs for virulence genes. End-point PCR was used to verify new trh and tdh primers for more accurate detection of Vv and Vp type strains. A novel Vv tdh gene pair showed promise, whereas the vvhA pair was no better than published primers. These in silico and preliminary end-point PCR data will inform future efforts in quantifying Vibrio with quantitative PCR. Finally, an exploratory study showed that Karenia brevis (Kb), a toxic dinoflagellate rampant in southwest Florida waterways, inhibited Vv growth by 150-fold, and Kb had little to no effect on Vp growth.

Show moreMicroplastic pollution is ubiquitous to water sources around the world, including freshwater, drinking water, salt water, and sea ice. Microplastics have also been documented in all parts of the water column from the sea floor and sediments to surface water. It was believed that microplastic pollution was concentrated in coastal areas with large human populations around the world. While remaining either entirely absent or minimal from remote areas where human influence is minimal such as in Antarctica, specifically the Antarctic Peninsula. This project determined microplastic concentration of three fjord habitats on the Western Antarctic Peninsula where glaciers are rapidly retreating within the fjords. Over a three-year period from 2017 to 2020 water samples were collected from the surface and benthos from 16 stations in Marian Cove, King George Island, Börgen Bay, Anvers Island, and Sheldon Glacier, Adelaide Island. For each station, three liters from the surface and three liters from the benthic were collected using a CTD rosette with Niskin Bottles, vacuum-filtered with a Buchner-Filter hand pump then, quantified under a compound microscope to determine the classification of microplastic, (fragment, fiber, or bead) color, and size. Comparisons over time and location were made in average microplastic per liter. It was determined that all the fjord habitats had microplastic present every year sampled, but the microplastic concentration was also increasing over time in the three fjords. This demonstrates that even with barriers such as the Antarctic Circumpolar Current, plastics are present and increasing in the Western Antarctic Peninsula during this time.

Show moreDuring the early 1700s and into the early 1800s in Louisiana, a unique community of free black people created a fluid political and cultural identity within New Orleans. Surrounded by plantation slavery, free black people living in this important urban port city accumulated a degree of wealth, property, and agency that free and enslaved people of color did not have access to in other areas of the South. Though this community faced many obstacles and limitations due to their precarious place within a hostile and rigid racial system, free black people, as individuals and as a community, used the often confusing and fluid nature of their racial identity to bolster their agency and place in New Orleans. One such way free black people accomplished this was through the extensive practice of apprenticeship, a labor practice that allowed young people to learn a skill from an artisan, who in exchange for their training, used the free or low wage labor from their apprentice. Using over four hundred contracts between free children of color, local artisans, and a sponsor, this research explores how apprenticeship was in part a formal educational opportunity for black youth. The role that family members, especially black mothers and white fathers, played in acquiring and sponsoring apprenticeships for their children attests to the importance of education and establishing relationships with local artisans and business owners in New Orleans. Using the data collected from these documents, as well as supporting public records, this research reveals the complex and interconnected ways that the free community navigated their material and cultural environment to survive, and often thrive, in the face of increased racial hostility and threats to free black agency in the decades leading up to the Civil War.

While nesting behavior of sea turtles is well understood, gaps in knowledge exist for inwater movements. This is especially true for neonate and small juvenile turtles, which are overall data poor at pelagic and early neritic stages. The use of satellite-linked platform terminal transmitters (PTTs) allows scientists to study sea turtle movements; however, long-term tracking of sea turtles comes with a unique set of challenges.

Show moreWhile nesting behavior of sea turtles is well understood, gaps in knowledge exist for inwater movements. This is especially true for neonate and small juvenile turtles, which are overall data poor at pelagic and early neritic stages. The use of satellite-linked platform terminal transmitters (PTTs) allows scientists to study sea turtle movements; however, long-term tracking of sea turtles comes with a unique set of challenges. Tracking durations can be brief and limited by technical failures. Most PTTs on small juveniles fail within one year. There is a general consensus among many biologists who tag small juvenile turtles that tags are failing due to premature detachment from carapace expansion. I tested this growth-caused detachment hypothesis through a series of controlled experiments. First, using empty red-eared slider (Trachemys scripta elegans) shells, I conducted axial load testing with model transmitters attached. Second, using juvenile red-eared sliders with model PTTs, I recreated the stress of shell growth on the epoxied-tag attachment. In both experiments, a suite of epoxies were tested, expansion factors were measured, and data was compared to sea turtle growth rates. This research contributes to the knowledge of how adhesives interact with a growing turtle shell.

Show moreThe decrease in the college-going population, along with the deregulation of the higher education sector has contributed to the consistent decline in undergraduate enrollment in several American universities and colleges, including the research site for this study. The National Student Clearinghouse Research Center (NSC Research Center, 2019) reported that the total enrollment of college students in the United States has decreased for 8 successive years (2011-2019), resulting in the closure or merger of some higher educational institutions. Scholars and strategic management professionals have proposed the use of strategic resources to help institutions achieve sustainable enrollment growth. Using a qualitative case study approach and the resourcebased view theory (RBV) as a theoretical framework, the study explored how select administrative stakeholders in a public university leverage brand reputation as a strategic resource for achieving sustainable undergraduate enrollment growth in the Southeastern United States. The RBV comprises four constructs (valuable, rare, inimitable, organize) that describe resources essential to distinguish an institution's brand. Eight participants were purposefully selected and interviewed. Findings from the study revealed that the administrative stakeholders employed several brand strategies including creating consistent brand messages, exploiting visual identity, highlighting high-impact practices, and leveraging the university's historic and geographic location to ensure sustainable enrollment. This study can inform higher educational leaders on how to strategically re-align their brand reputation management strategies to achieve long-term enrollment sustainability. Since this study's findings may be more relevant to public sector institutions, future studies can explore the same phenomenon among proprietary and faithbased institutions.

Show moreCollege students' inability to complete necessary mathematics coursework due to elevated mathematics anxiety levels can hinder degree completion and affect graduation rates. Institutes of higher education should offer students enrolled in a developmental mathematics course opportunities outside of the classroom that potentially lower mathematics anxiety levels and increase self-efficacy levels. The purpose of this quantitative correlational study was to examine the correlation between the frequency of visits to a mathematics learning support center and mathematics anxiety levels and self-efficacy among nontraditional developmental mathematics students at a 2-year college in Florida. The study applied Bandura's (1986) social cognitive theory that explains interactions that exist between behavior (mathematics anxiety), personal factors (self-efficacy), and environmental events (learning support centers) as the theoretical framework. I utilized convenience sampling to collect survey data from 16 participants. The data analysis revealed a statistically significant difference between preintervention and postintervention mathematics anxiety levels (p = 0.028) and self-efficacy levels (p = 0.0075). However, a statistically significant correlation did not exist between the frequency of visits to a mathematics learning support center and participant levels of mathematics anxiety (p = 0.241) and self-efficacy (p = 0.850). The study results have implications for current policies by examining the correlation between attendance at learning support centers and developmental mathematics students' mathematics anxiety and self-efficacy levels. Because the sample size was significantly reduced due to COVID-19 restrictions, I suggest future research with a larger sample size should be conducted.

Show moreFermented Summer is a collection of three stories: Fermented, Evaporated, and Distilled that explore themes of Southern Gothic American Literature in a modern, short story format in a small fictional Floridian town surrounded by swamp land. The characters experience troubles of southern culture: alcoholism, prejudice, alienation, poverty, transgression, and decayed settings. Each story depicts encounters of a different time in the same place whilst switching between central figures' narration. The expectation of Fermented Summer is to examine the multifaceted relationship of humanity and its ecological surroundings, putting pressure on the already brittle bonds with nature. Its purpose is to explore the degree to which humanity is recognizable without its ancestral and nearly primal synergy with the land and life. The figures of Fermented Summer highlight not the struggles of impoverished southerners, but the degrading relation of humanity to the earth itself. Each character has their own conflicts and challenges, ultimately placing the troubles with Del, the youngest, to sort through the remains of her dying homeland and familial relations.

By using the Aeneid as a resource for A True Reportory, I argue that Strachey is committed to creating a new and active history for Jamestown by connecting the ongoing foundation of Jamestown to that of the Roman Empire, an empire destined for greatness, in the attempt to align his account with the promotional goals of the Virginia Company. In particular, I will show that Strachey leverages Rome's greatness to induce the British population to take a more active role in the larger North American colonial project, while also using uniquely Roman paradigms of colonialism to legitimize Britain's possession of Jamestown and place the British experience within a known colonial framework.

Show moreThe overarm throw is a difficult multi-limb task because the overarm throw requires synchronized dexterity of the entire body. Research has determined that the inability to throw hinders children's participation in physical activities. The dynamic systems theory, which describes the interactions and processes that manipulate development, framed this quantitative study to investigate the effects of overarm throw instruction without a ball accompanied by verbal, directional cueing set to music with counts (decontextualized skill-cueing). A repeatedmeasures analysis of variance analyzed the process scores of the overarm throw for accuracy across three periods for 78 girls and boys in kindergarten and first and second grades. Data analysis found the main effect comparing the genders was significant, indicating a difference in the process scores between genders across the three periods. Descriptive statistics indicated the means for both sets of participants gradually increased after the pretest through the posttest and the retention test with the highest mean at retention test; yet, the means for the female participants were not as high on any test as were the means for the male participants. Further, the main effect between the control and treatment groups was also significant. Both groups' process scores increased over time from pretest to posttest; however, the control group's scores decreased during the retention test, as evidenced by the means and standard deviations. The study upholds the dynamic systems theory constructs that posit the body's multiple physiological components combine to create over-time skill variability in the body relative to the task, individual, and environment.

Show moreThe researcher investigated whether personality type and learning style predicted performance in distance education. Thirty-four participants from 3 sections of Art Humanities completed online the Myers-Briggs Type Indicator and the Learning Styles Inventory. Using regression analysis, it was determined that neither personality type nor learning style had a statistically significant effect on student performance in this setting. However, the data did reveal some apparent self-selection of the learning environment. Sensors outrepresented Intuitives by a large scale, identifying further areas for research. A binomial test was used to prove these results were not random. As some scholars have noted, COVID-19 has exacerbated existing inequities and economic insecurities that increase the risk of harassment. Sexual harassment (SH) involves conduct of a sexual nature that creates an intimidating or hostile work environment or interferes with an individual's job performance. This speculated increase in SH due to COVID-19 could relate to an increase in Stockholm syndrome (SS) among essential workers, as many essential workers may stay at their workplace due to benefits (e.g., finances, healthcare) despite having experienced abuse. As such, the current study applies Stockholm syndrome as a framework to examine the potential relationship between SH and SS, and the effects that various factors (e.g., essential worker status, source of harassment) have on this relationship. One-hundred and twelve participants completed online surveys using Amazon's Mechanical Turk (MTurk). Analyses revealed a positive relationship between SH and SS. Furthermore, essential workers reported higher levels of both SH and SS than their non-essential counterparts. This thesis bridges the gap between SH and domestic violence literature, such that it is the first to apply the SS framework to workplace instances of SH. Future research calls for examining the influence of race and power in influencing this relationship, as well as examining the long-term effects of feelings of SS in the workplace.

Show moreSubmarine groundwater discharge (SGD) connects terrestrial groundwater to coastal surface waters through porous sediments. This research tracked dissolved nutrients as they traverse the subterranean estuary by measuring nitrogen stable isotope ratios in association with SGD inputs to nearshore beds of Thalassia testudinum. Variations of SGD-transported nutrients into the local environment (including porewaters and bottom waters) in which Thalassia is growing was investigated. Analysis was carried out for variations in elemental abundance and stable isotope composition of seagrass in areas receiving SGD compared to control areas in which no SGD is measured. Eight site locations were sampled within Florida's Gulf Islands National Seashore's Naval Like Oaks (NALO) Preserve for bottom-water nitrate, nitrite, ammonium and phosphate; physical water quality parameters (dissolved oxygen, specific conductivity, temperature, pH, and turbidity); δ15N in pore-waters and groundwater transect; and dissolved radon. Additionally, Thalassia testudinum IRMS analysis for δ15N to investigate SGD influences on N ratios and stable isotope composition in the local seagrasses, including spatial and tidal controls on any variability in water column chemistry and seagrass biogeochemistry. Overall, there was not a significant correlation between SGD inputs and the stable isotope values found in Thalassia. However, significant findings linking SGD to atmospheric precipitation and isotope ratios to seagrass growing seasons were unearthed. The results of this research could prove advantageous for policymakers and environmental managers as they deal with pollution and conservation efforts surrounding seagrasses.

Show moreMeshless methods utilizing Radial Basis Functions(RBF) have been widely used to find numerical solutions for Partial Differential Equations(PDEs). Unlike the other numerical methods, meshless algorithms are significantly simpler to implement as they do not require a mesh in the simulation domain. Rolland L. Hardy, an Iowa State geodesist, was the first to study using RBF for scattered data interpolations in the early 1970s. He introduced his Multiquadric(MQ) RBF, which has been used to obtain numerical solutions for various types of RBF interpolation problems. In addition to that, E. J. Kansa, in the very early 1990s, made the first attempt to extend RBF interpolation to obtain solutions for PDEs. In this thesis, we propose a numerical scheme, which has been based on Kansa's method, to solve time-dependent PDEs. In contrast to already existing methods for solving time-dependent PDEs, our model treats the time variable the same as a spatial variable. However, the accuracy of the RBF numerical methods highly depends on the shape parameter, c, which is associated with the RBF. The value of the c that guarantees the highest accuracy is problem dependent and it is called as the optimal value of c. Even with the optimal value of c, it is not possible to achieve a significantly high accuracy compared to existing methods. In order to enhance the level of accuracy, we introduce \Ghost Points" into the computational domain. While traditional RBF based numerical methods place the centers exclusively inside the computational domain, the ghost point approach expands the region of the centers inside and outside the computational domain. Our numerical results suggest that the accuracy of the numerical results has been significantly increased by the ghost points.

- Abstract/Description

In mammals, retinal injuries and photoreceptor degeneration (PD) can damage photoreceptors causing permanent blindness. However, retinal injury in zebrafish (Danio rerio) elicits a rapid stem cell-based response that regenerates photoreceptors and restores vision. Crucial to this are the Müller glia (stem cells) that generate multipotent progenitor cells, which regenerate photoreceptors. Photoreceptor regeneration requires accurate control over the immune response (inflammation), cell cycle...
Show moreIn mammals, retinal injuries and photoreceptor degeneration (PD) can damage photoreceptors causing permanent blindness. However, retinal injury in zebrafish (Danio rerio) elicits a rapid stem cell-based response that regenerates photoreceptors and restores vision. Crucial to this are the Müller glia (stem cells) that generate multipotent progenitor cells, which regenerate photoreceptors. Photoreceptor regeneration requires accurate control over the immune response (inflammation), cell cycle exit, and differentiation. Understanding the mechanisms which control photoreceptor regeneration in zebrafish could lead to treatments for blindness that stimulate Müller glia to reestablish vision in humans. Past investigations have demonstrated that microRNAs (miRNAs) are essential regulators of retinal neurogenesis, but lacking is an understanding of the roles of miRNAs in regulating photoreceptor regeneration. Preliminary data with miR-18a mutant fish generated using CRISPR/Cas9 gene-editing indicated that this microRNA regulates photoreceptor regeneration. The objective of this study was to determine if and how miR-18a, following light-induced photoreceptor injury, functions to regulate the cell cycle and/or differentiation in Müller glia and photoreceptor progenitors. In-situ hybridization (ISH) and immunohistochemical (IHC) labeling showed that miR-18a is expressed in microglia, proliferating Müller glia and photoreceptor progenitors, suggesting roles at both early and later stages of the photoreceptor regeneration response. Bromodeoxyuridine (BrdU) and proliferating cell nuclear antigen (PCNA) immunolabeling experiments showed that, following photoreceptor injury, there are more proliferating cells in miR-18a mutant (CRISPR) retinas compared with x wild-type (WT), demonstrating that miR-18a regulates the cell cycle. Expression of miR-18a in Müller glia and microglia (macrophages) indicates a role in the early regeneration response during which inflammation plays a critical role, and microRNA databases predict that miR- 18a might interact with and regulate several molecules involved in inflammation. These results led to the hypothesis that miR-18a regulates photoreceptor regeneration by regulating inflammation. As an initial test of this hypothesis, ISH was used to show that, in miR- 18a mutants compared with WT, the inflammatory mediator NFkB is expressed for a more extended period of time, indicating that miR-18a might typically function to suppress inflammation. To test this, dexamethasone (corticosteroid) was administered at critical time points to reduce inflammation levels in the miR-18a mutants. By blocking inflammation from days 2 to 6 post-injury, the treatment rescued the phenotype in the mutants, reducing the numbers of proliferating cells to the levels observed in WT fish. Finally, to determine if miR- 18a also regulates photoreceptor differentiation, ISH for rods and cones showed that miR- 18a mutant fish generate photoreceptors slower than wild-type fish but that by 14 days postinjury (dpi) miR-18a mutant fish generate more cones than WT. Together, these results demonstrate that miR-18a regulates the cell cycle and photoreceptor differentiation through molecular control over inflammation.

- Abstract/Description

Anne Bannerman's "The Prophetess of the Oracle of Seäm" has not been studied as thoroughly as her most well-known poem, "The Dark Ladie." Indeed, none of the critical work on Bannerman to this point has focused exclusively on "Prophetess," the second poem in Bannerman's critically-maligned Tales of Superstition and Chivalry. This paper offers a standalone study of Bannerman's "Prophetess," analyzing the poem as an exemplar of Deleuzian eternal return. More specifically, it focuses on the...
Show moreAnne Bannerman's "The Prophetess of the Oracle of Seäm" has not been studied as thoroughly as her most well-known poem, "The Dark Ladie." Indeed, none of the critical work on Bannerman to this point has focused exclusively on "Prophetess," the second poem in Bannerman's critically-maligned Tales of Superstition and Chivalry. This paper offers a standalone study of Bannerman's "Prophetess," analyzing the poem as an exemplar of Deleuzian eternal return. More specifically, it focuses on the manner in which "Prophetess" enacts two key Deleuzian ideas, repetition and fundamental encounter, thereby opening up the possibility of a uniquely Gothic epistemology that problematizes the Enlightenment insistence on clarity and revelation.

Show morePrevious research studying language brokers (i.e., children/adolescents who translate for family members) has indicated a positive correlation between frequent language brokering and gains in cognitive development. However, there is evidence documenting elevated levels of anxiety in brokers, which may undermine cognitive developments. The purpose of this study was to examine how the anxiety levels would independently predict academic motivation and learning strategies in college and examine how anxiety levels would interact with frequency of brokering. Specifically, language brokering frequency is predicted to have independent positive relationships with academic motivation and learning strategies. Language brokering frequency is expected to have a positive relationship with anxiety levels. The interaction between language brokering frequency and anxiety is expected to interfere with academic motivation and learning strategies. Our hypotheses and support from previous articles were partially supported; while a relationship between language brokering frequency, anxiety, and learning strategies was not indicated, a significant relationship was found between language brokering frequency and academic motivation including some of its subcomponents. These findings help to more directly understand the context of the language broker in emerging adulthood in higher academia and the impact on cognitive outcomes during this important transition into adulthood.
