The increasing diversity in American public schools presents challenges to teachers and administrators. Current methods of reading instruction for English language learners (ELLs) have been ineffective to meet their needs in acquiring vocabulary. Meanwhile, the amount of time afforded ELLs to become proficient with grade-level vocabulary presents challenges for all stakeholders. Consequently, ELL students are not demonstrating growth on Florida's annual standards assessments. The purpose of...
Show moreThe increasing diversity in American public schools presents challenges to teachers and administrators. Current methods of reading instruction for English language learners (ELLs) have been ineffective to meet their needs in acquiring vocabulary. Meanwhile, the amount of time afforded ELLs to become proficient with grade-level vocabulary presents challenges for all stakeholders. Consequently, ELL students are not demonstrating growth on Florida's annual standards assessments. The purpose of this qualitative descriptive case study was to explore the vocabulary instruction used by elementary teachers of ELLs in the southeastern United States. The study's contextual framework comprised the five hypotheses of Krashen's second language acquisition theory: acquisition-learning, monitor, natural order, input, and affective filter. The research questions aligned with the theoretical framework and were the means used to identify strategies and describe instruction for ELLs. Nine purposefully selected participants provided rich descriptions of strategies and curricula used during vocabulary instruction to improve language acquisition. Research findings suggest the benefit of promoting partnerships among stakeholders to support vocabulary instruction for ELL students and the importance of continued professional development of vocabulary instruction strategies for staff. An unexpected finding was the value placed on using media for differentiated instruction of academic vocabulary with ELL students. The study provided information for policy and practice on the value of differentiated curriculum with an emphasis on ELLs' language acquisition needs. Future researchers could explore the use of auxiliary resources for ELL students, providing additional opportunities for differentiation in reading vocabulary instruction.

- The violence comes soon after: LGBTQ+ perceptions of safety and its effects on mental health in Pensacola.
- Author
- Harshman, Brenna
- Abstract/Description
-
In Pensacola, Florida, there are many conservative residents who object to the presence of LGBTQ+ members in the community despite the long, rich history of relative LGBTQ+ tolerance. Due to the outward display of intolerant behavior, many LGBTQ+ people question their ability to safely express their sexual orientation and gender identity. This paper explores the primary data on main stressors that affect the perception of safety among the LGBTQ+ community in the Pensacola area as well as the...
Show moreIn Pensacola, Florida, there are many conservative residents who object to the presence of LGBTQ+ members in the community despite the long, rich history of relative LGBTQ+ tolerance. Due to the outward display of intolerant behavior, many LGBTQ+ people question their ability to safely express their sexual orientation and gender identity. This paper explores the primary data on main stressors that affect the perception of safety among the LGBTQ+ community in the Pensacola area as well as the mental health consequences linked with the stress of feeling unsafe. Data was gathered through participant observation and semi-structured interviews. I hypothesize that the LGBTQ+ community in Pensacola is more likely to have poor mental health and this inequity is linked to discrimination and feeling unsafe.

This paper investigates William Strachey's A True Reportory, a stylized eyewitness account of Strachey's 1609-1610 voyage to the Jamestown colony, showing how the text utilizes Vergil's Aeneid to set a precedent for the British colonization of the New World.

Show moreThis paper investigates William Strachey's A True Reportory, a stylized eyewitness account of Strachey's 1609-1610 voyage to the Jamestown colony, showing how the text utilizes Vergil's Aeneid to set a precedent for the British colonization of the New World. 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.

- Using ocean circulation models to explore factors influencing variability in hatchling sea turtle dispersal.
- Author

- Abstract/Description

When sea turtles hatch, they journey offshore to the open ocean. Currents are one of the factors that influence the success of this journey. The spatial ecology influencing hatchling turtles must be evaluated to protect them most effectively. Here, I examine how spatial, temporal, and climatological factors impact the dispersal of turtle hatchlings via ocean currents.

The spatial ecology influencing hatchling turtles must be evaluated to protect them most effectively. Here, I examine how spatial, temporal, and climatological factors impact the dispersal of turtle hatchlings via ocean currents. I use the HYCOM global model combined with the Ichthyop particle simulator to measure the current driven dispersal of sea turtles. In a global analysis, spatial traits are a key factor driving dispersal. Annual variability in ocean currents also impact how far turtles can go. The differences in dispersal distance expand across sites and years the longer the turtles are in the water. I also evaluated the spatiotemporal variability in dispersal distance for the Gulf of Mexico endemic Kemp's Ridley sea turtle (Lepidochelys kempii) and related that variability to the frequency and severity of hurricanes. There are important spatiotemporal differences in dispersal that suggest varying levels of hatchling dispersal for each rookery. Further, increased frequency and intensity of hurricanes decreases the dispersal of hatchlings in the Gulf of Mexico. These findings can assist in model building and conservation planning for sea turtles worldwide.

Genetics at the population level can illuminate important information about the evolutionary health and history of a population, which can be especially important for threatened or endangered species. The Alabama sturgeon (Scaphirhynchus suttkusi) is the rarest and most endangered species of sturgeon in the world.

Show moreGenetics at the population level can illuminate important information about the evolutionary health and history of a population, which can be especially important for threatened or endangered species. The Alabama sturgeon (Scaphirhynchus suttkusi) is the rarest and most endangered species of sturgeon in the world. The decline of this species is attributed largely to historic overfishing and habitat fragmentation by the installation of dams and impoundments in the Mobile River Basin. Despite extensive catch efforts through the conventional catch methods, only six individuals have been captured since 1997. Recently, however, positive detections of the Alabama sturgeon in the Mobile River Basin have been confirmed using environmental DNA (eDNA) water samples. This research used 61 eDNA samples that tested positive for Alabama sturgeon DNA to investigate and inventory the population genetic structure. Using high throughput sequencing (metabarcoding) and bioinformatic analyses, ten haplotypes were identified. Calculations on genetic differentiation based on locality revealed that three major dams may be a significant barrier to gene flow. The population genetics data gleaned from eDNA samples will ultimately provide conservation managers with valuable information for future decision-making and management.

Show moreAnna Letitia's "A Summer Evening's Meditation" exhibits a feminine poetics of space that portrays not only the poetic speaker but also the universe itself as distinctly feminine and feminist. This poetics genders the cosmos and permits the poetic speaker to express her longing to explore the universe just as it allows Barbauld to engage in the scientific discourse of astronomy. The speaker herself fulfills her longing as she exercises agency to explore and recreate space in terms of what Elizabeth Grosz identifies as a "freedom from" constraint or oppression and a "freedom to" respond with action (140). The poem's embracing "freedom to" is a radical move that eliminates the woman's need to attain freedom from an oppressor and instead urges her to perform her freedom through agentic action. Agency, in this sense, produces an embodied female subject and empowered female voice able to contribute to ways of knowing and being. As such, the action of "Meditation" functions metaphorically as a critique of eighteenth-century British culture that reinforced male control over scientific discovery, knowledge production, and agency. Reading Barbauld's "Meditation" through Groszean feminist theory re-envisions the poem as an argument for female freedom in its fullest, freest sense.

Show moreTurnaround principals of chronically inadequately performing schools faced myriad challenges and required the requisite skills to derive positive transformational change (Duke, 2015). Challenges include identification of the root causes, development of a cohesive turnaround plan, successful implementation, and progress monitoring (Duke, 2015). The purpose of this qualitative instrumental case study was to explore best practices of principals leading turnaround reform efforts. Four cases whereby turnaround principals who have successfully derived rapid school-improvement results provided information that can be used to understand the best practices inherent to a successful turnaround. The research was conducted at each school, and data was gathered from interviews, field observations, and artifacts. Rapid school improvement is nebulous; however, precise methods are limited. Deming's insistence on the leader's role as a predominant factor in improving productivity complements the turnaround principal's role in the improvement process. His work and scholarship influenced the conceptual framework created for this study. The conceptual framework included identification, development, implementation, and assessment and provided a sequential route to understanding nuances inherent in a school turnaround effort. A convergence of evidence model was used to identify common themes and synthesize conclusions. A comprehensive approach is required to understand the enormity of a successful turnaround effort. Similarly, instructional leadership, communication, tenacity, and recognition are essential practices that are evident in a successful turnaround effort. Findings can be used to scale turnaround efforts and build expertise. Questions for future research include understanding the varying contexts, leading schools with different demographic profiles, and expanding similar facets using other approaches.

Current retention models generally follow traditional relational marketing paradigms and therefore do not account for the complexities introduced by the presence of an independent intermediary. Given an anonymous policy dataset consisting of correlated, high-dimensional, and high-cardinality categorical/numeric data; current data mining methods are used to construct a retention model with practical applications. Additionally, predictive features that capture intermediary-related information are engineered and designated as candidate features. Candidate features are selected for αnal model inclusion using various data mining approaches to feature importance measurement and feature selection.

Show moreRecent societal shifts underscore the importance of preparing social work students for effective practice with diverse populations. Lack of cultural competence among social workers is a problem that can negatively impact communities (Sue et al., 2009). Diversity education is thus a fundamental component of accredited social work graduate programs. The purpose of this convergent mixed methods study was to explore the transformative impact of diversity education on the cultural competence of graduate social work students at a public university in the Southeastern United States. Transformative learning theory, which addresses the change process in education (Mezirow, 1991), offered a framework to explore emergent cultural competence for one cohort of 49 full-time social work students selected as a case study. A convergent mixed methods design with an embedded case study approach offered a multifaceted understanding of participant experiences. Extant field assessment data served as a quantitative data source. Classroom observation and interviews provided qualitative data. Data sets were analyzed then merged and compared. A paired-samples, two-tailed t test indicated a statistically significant difference in mean cultural competence scores on the field assessment between midterm (M = 41.43, SD = 8.12) and final (M = 47.18, SD = 9.63); t(27) = -5.9, p < .01, d = 0.65. Thematic analysis of qualitative data revealed themes of developing cultural competence as well as constructs and phases that are associated with transformative learning. Integration and interpretation of quantitative and qualitative data offered an expanded understanding of emergent cultural competence within social work diversity education.

Show moreWith global temperatures achieving new extremes each year, it is not immediately clear the effect these temperatures will have on American alligators (Alligator mississippiensis). Thermal tolerances have been estimated on American alligators before, but a full thermal niche has never been determined. An eccritic temperature, thermal preference, has been estimated for alligators, but results have varied. I used standardized thermal methodologies to estimate acclimation ranges, upper and lower acclimation response ratios, thermal niche areas, and the eccritic temperature in adolescent alligators. Alligators had an upper chronic limit of 39.1°C and a lower chronic limit of 16.2°C. Alligators exhibited a larger gained cold tolerance zone in their niche than anticipated at 131.6°C 2 and an intrinsic tolerance and gained heat tolerance zones of 509.7°C 2 and 61.4°C 2 , respectively. Cold acclimation response ratio was roughly twice that of the heat response, with alligators losing or gaining 0.5°C or 0.2°C heat tolerance per every 1°C change in acclimation temperature. Alligators expressed an eccritic temperature of 32°C with little variation between animals. Evidence suggested there is an undescribed physiological process that allows alligators to acclimatize to lower temperatures. Comparing thermal niche and eccritic temperature data to temperature trends in alligator's natural habitat suggested that alligators could be affected by changing temperatures.

Show moreRed-eared sliders (Trachemys scripta elegans) are considered one of the most abundant and successful invasive turtle species in the world. Currently, red-eared sliders are known to have reproducing populations on every continent with the exception of Antarctica. In areas where they have become established, red-eared sliders often outcompete and in some areas extirpate native turtle fauna. A key adaptation recognized in red-eared sliders is their ability to survive a wide range of environmental temperatures. Across their native range, the turtles are noted to survive long-term winter freezing temperatures, as well as prolonged exposure to summer temperature extremes. Although temperature plays an important role in shaping red-eared slider ecology and distribution, relatively little is known about their thermal requirements. This study is the first to use Critical and Chronic Thermal Methodology to define the red-eared slider's thermal niche. The chronic maximum temperature was 43°C ± 0.3, while the chronic minimum was 18°C ± 0.3. Critical Thermal Maximum increased in correlation to acclimation temperature, 41.8°C ± 0.3 at 15°C, 43.2°C ± 0.3 at 22°C, 44.1°C ± 0.5 at 28°C, and 45.7°C ± 0.2 when acclimated to 35°C. Critical Thermal Minimum also increased in relation to the acclimation temperature, -0.04°C ± 0.3 at 15°C, 2.7°C ± 0.1 at 22°C, 3.3°C ± 0.3 at 28°C, and 5.1°C ± 0.2 when acclimated at 35°C. Using the results of this study, the thermal polygon of red-eared sliders was able to be quantified and paves the way for future thermal studies in this species.

Show moreThe Whitespotted bamboo shark, Chiloscyllium plagiosum is a species of longtail carpet shark native to the Indo-Pacific region known as the Coral Triangle. Temperatures across much of the geographic range of the Whitespotted bamboo shark are rising, and it is not immediately clear if the species has the physiological capacity to withstand the impending rise in sea surface temperatures expected by the end of the century. Although listed by the International Union for Conservation of Nature as Near Threatened in 2006, their current conservation status is unknown. Indeed, thermal requirements of elasmobranch fishes in general are grossly understudied with empirical data available for only five of the more than 1200 extant elasmobranch species. The purpose of this study was to quantify thermal niche requirements of the Whitespotted bamboo shark by estimating key thermal metrics including intrinsic tolerance, upper and lower critical temperatures, thermal acclimation range, and upper and lower temperature acclimation responses. The results are interpreted and discussed in relation to current and potential future thermal conditions across the shark's traditional geographic range. The bamboo shark data presented here are the first to describe thermal requirements in a selachian elasmobranch.

Acclimation dynamics are an important, but little studied, aspect of fish thermal ecology, that quantify the pattern and speed with which fish readjust to acute changes in water temperature. When exposed to an acute temperature shift, fish implement a sequence of behavioral, physiological and/or molecular changes to ameliorate adverse temperature and restore homeostasis.

Show moreAcclimation dynamics are an important, but little studied, aspect of fish thermal ecology, that quantify the pattern and speed with which fish readjust to acute changes in water temperature. When exposed to an acute temperature shift, fish implement a sequence of behavioral, physiological and/or molecular changes to ameliorate adverse temperature and restore homeostasis. Homeostatic changes due to temperature change can be tracked by monitoring shifts in critical thermal maximum values. Acclimation dynamics have been determined for several species of bony fish but are unknown in other fish groups. In this study acclimation dynamics were determined for three groups of Atlantic stingrays (Hypanus sabinus) acutely transferred to higher temperatures. Atlantic stingrays acutely transferred from 15 to 23°C, 23 to 30°C, or 30 to 34°C, accrued heat tolerance relatively quickly, with most of the acclimation process completed between 2 and 3 days. Atlantic stingrays acclimate more quickly to temperature change than teleost fishes. For example, guppies (Pocillia reticulata) require 15 days to fully acclimate. Channel catfish (Ictalurus punctatus) took 15-20 days to reach full acclimation. Sheepshead minnow -- a hyperthermic specialist capable of enduring temperatures of nearly 45° - took 17 days to reach full acclimation (Fangue et al., 2014). Atlantic stingrays are regularly exposed to rapid, unexpected temperature shifts and the ability to acclimate quicklyr allows stingrays to exploit shallow thermally variable habitats.

Show moreSubmarine groundwater discharge (SGD) is a pathway of nutrient loading into marine systems. SGD is described as the direct discharge of fresh or recirculated groundwater into the near-shore environment. This study aims to qualitatively identify nutrient transformation within the subterranean estuary (STE), which is a point of mixing between fresh groundwater and seawater where several chemical reactions occur. The biogeochemical conditions in porewater were identified using a push point piezometer. A pieozomanometer survey was conducted to determine the nutrient flux into Santa Rosa Sound, Gulf Breeze, Florida. Nutrient concentration data were obtained by analyzing porewater samples from two sampling dates, June 16, 2019, and September 29, 2019. Upward velocity measurements were made on January 27, 2020. When comparing the two sampling dates, the subterranean estuary shifts from freshwater input into the system and salinity plots mimic the distribution of nitrogen within the STE. Phosphorus, pH, and oxidation-reduction potential (ORP) profiles were compared. In areas with low ORP and low pH, they indicate the possibility of iron oxidation and the possible presence of an "iron curtain". In this area, dissolved phosphorus is likely to precipitate from solution. Total dissolved inorganic nitrogen from porewater averaged 0.7 mmol d-1 per m shoreline. Upward velocity measurements showed that velocity increased with distance offshore, a trend that could be explained by a change of hydraulic conductivity and the patchiness of porewater substrate, where preferential flow through SGD favors sediments further offshore.

Show moreMicrobial communities are greatly influenced by natural environmental factors as well as disturbance and recovery due to anthropogenic effects and events. Of equal interest is their resiliency and recovery from those disturbances. For the purpose of this study, temporal was defined in three ways: seasonal variation, daily diel variation, and disturbance event effects and response. For the past three years, we maintained a bi-weekly sampling of water from the Pensacola Beach Pier to address long term seasonal variability in biomass, productivity community structure, and physico-chemical parameters. Diel variation was measured using periods of increased sampling frequency to every six hours over a fifty-hour timespan. These diel samples were conducted quarterly in one year to compare seasonal variation. Temperature was the largest driving force in both long term and short-term variability for Pensacola Beach for the three years studied. Response to Hurricane Nate and Hurricane Michael was evaluated in years 2 and 3. Sampling was increased to once daily before, during, and after each storm either made landfall or passed by Pensacola Beach. Data from these storm events was compared to the previously defined typical values for that time of year using the time series to determine the disturbance effect and recovery period specific to the microbial ecology due to these storms. Data from both storms showed an immediate response in microbial communities with an equally rapid recovery period.

Show moreMany American children live in poverty in the United States and struggle daily with seven basic resource deprivations that represent the constructs of this study. The constructs are: "health and nutrition, vocabulary, effort and energy, mindset, cognitive capacity, relationships, and stress" (Jensen, 2013a, p. 8). The purpose of this interpretative phenomenological analysis (IPA) was to explore the perceptual experiences of elementary school teachers working with students who live in poverty and attend a low-SES elementary school in the Southeastern United States. This study used the framework of Jensen's brain-based learning theory to explore the phenomenon of students living in poverty, which was the impetus for development of Jensen's theory (Jensen, 2013a). The findings support Jensen's theory regarding academic engagement influences relative to the constructs. Using an IPA , the findings reveal that participants felt students living in poverty faced challenges in academics that more affluent students did not encounter but still had the capacity to learn at some level and were academically responsive to strategic, personal attention from the participant teacher. Participants revealed parental feelings of responsibility for the care and nurturing of students, which often grew out of a lack of parental involvement from students' parents or guardians. Participants discussed feelings of responsibility to procure needed resources for students when available and to provide resources personally when unavailable. Finally, participants expressed feelings of love and ministry for students and believed that positive influences in the lives of students living in poverty could change students' lives in a beneficial manner.

Show moreMany factors can influence a teacher's self-efficacy beliefs, including the support of his or her administrators--the principal and assistant principal. This interpretive phenomenological study sought to describe the influence that administrator support had on teacher self-efficacy. The conceptual framework of this study was Bandura's (1986) social cognitive theory with a specific focus on the construct of self-efficacy (Bandura, 1977a). The research questions addressed the impact of a supportive administrator and sought to describe specific examples of administrator practices that influenced individual teacher self-efficacy. Data were collected through in-depth interviews with teachers in a school district in the southeastern United States. Participants were selected for interviews based on their experiences in education with multiple administrators. All interviews were taped, transcribed, and analyzed using coding and thematic analysis. The study provided detailed descriptions of how administrative support influenced teacher self-efficacy and examples of supportive administrative practices. Six supportive administrator practices were identified: communication, monitoring and evaluating instruction, providing contingent rewards and recognition, situational awareness, consideration, and consistency. Supportive administrator practice influenced teacher self-efficacy through five themes: increasing confidence, motivation, feeling valued, reinforcement, and leaving or staying in a school or the profession. This study could contribute to positive change in administrator/teacher relationships and help administrators increase teacher self-efficacy, thereby leading to increased quality of instruction, focus on academics, positive learning environments, and student achievement.

Pedestrian dynamics models are used to simulate the walking movement of people. A multi-dimensional parameter sweep in these simulations can account for the variability in human movement patterns. A conventional lattice-based parameter sweep suffers from the following limitations that leads to a large computational effort: (i) it does not explore the parameter space efficiently, and (ii) it leads to inefficient convergence checks in high dimensions, which are required for robust scientific...
Show morePedestrian dynamics models are used to simulate the walking movement of people. A multi-dimensional parameter sweep in these simulations can account for the variability in human movement patterns. A conventional lattice-based parameter sweep suffers from the following limitations that leads to a large computational effort: (i) it does not explore the parameter space efficiently, and (ii) it leads to inefficient convergence checks in high dimensions, which are required for robust scientific results. Low discrepancy parameter sequences (LDS) have asymptotically better uniformity than a lattice and overcome both the above limitations. However, they have the following limitations: (i) a low-overhead parallelization leads to significant load imbalance, and (ii) the convergence rate worsens with dimension. In this thesis, we examine whether pseudorandom sequences can overcome these defects. While pseudorandom sequences have asymptotically worse convergence rates, the rate is independent of dimension. Consequently, it is possible that they have lower error for realistic sample sizes. In addition, we explore the potential of (i) a hybrid parameter sweep, where a small number of important dimensions use LDS while the other dimensions use a pseudorandom sequence and (ii) a parallel LDS, which can potentially yield good load balance. We also examine whether the convergence criteria used in previous work are necessary. Prior work shows that the existing convergence criteria are sufficient for accurate results. However, if they are not necessary, then one may perform a smaller number of simulations to obtain accurate results. Our empirical results show that while a parallel LDS has low load imbalance, its convergence rate is too poor to be beneficial. Hybrid and pseudorandom parameter sweep, on the other hand, show moderately x worse convergence than LDS for high accuracies, but good load balance. We also find that the prior convergence criteria are too strict, with two of the four criteria not being necessary. We use these insights to efficiently evaluate new boarding procedures introduced in airplanes during the COVID-19 pandemic. We show that these procedures actually increase infection risk. Our results promise to help a variety of other applications that employ large parameter sweeps.

The 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.

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.
