Show moreFifteen-year-old Arthur Penn has had a rough week. Not only has her ghostly companion, Merlin, been disappearing and keeping more secrets than before, but the girl Arthur saved over the winter holiday from a dangerous encounter has attempted to take her own life. Unable to ignore her own guilt and sense of responsibility towards the girl, Mel-Rose, Arthur decides to visit her in the hospital, even if Mel-Rose can't respond. Only moments after arriving, a sudden blackout at the hospital is the perfect cover for a newly awoken Mel-Rose to lead Arthur to the hospital's basement. Arthur follows, only to discover that not only has Merlin possessed MelRose's body, but that something called a breach has opened in the hospital's basement, and Merlin needs Arthur's help fighting off the gremlins and plants which have appeared in order to close it. When all is said and done, Merlin finally explains what is going on to Arthur. Not only is she the reincarnation of the fabled King Arthur, but it is up to her and Merlin to shut the doors of Avalon before more magic spills into the world, polluting and mutating the world as they know it.

Show moreThis project proposes book club pedagogy as a framework for altering traditional curricular design and attending to a more egalitarian style classroom. In these settings, students engage with writing that pushes beyond their comfort zone and allows them to see different perspectives, giving them skills to engage in culturally diverse environments. Participation in Book club classrooms enable "critical literacy," which creates student access points to participate and engage with texts and societal issues that are "interpreted through personal and cultural realities" (Freire & Macedo, 1987; Wood & Jocius, 2013). When utilizing personal experiences and interpretations of texts through various lenses, students participate in conversations regarding disabilities, stereotypes, and social action, and they evaluate their own experiences through reflective writing processes. In addition to affording students with opportunities to utilize their critical thinking skills, book club pedagogy is often conducted in a classroom setting crafted to provide flexible, open spaces rather than orderly rows of desks. To maintain an egalitarian environment, students take turns moderating the class discussion, enabling leadership experience to transfer from student to student. Book club pedagogies encourage students to engage in multimodal ventures when responding to complex texts, either through drawings, videos, blog posts, posters, or interactive games.

- Challenge-hindrance stressor framework and work-family outcomes: the moderating effects of individual learning goal orientation.
- Author
- Cremeans, Danielle Nicole
- Abstract/Description

The challenge-hindrance stressor framework focuses on individuals' appraisal of stressors as challenging or hindering. Most literature focuses on applying the challengehindrance stressor framework to performance outcomes. In contrast, the current study applies the framework to work-family outcomes while also examining the potential moderating effects of individual learning goal orientation (LGO). Ninety-seven participants completed online surveys through Amazon's MTurk. Analyses revealed a...
Show moreThe challenge-hindrance stressor framework focuses on individuals' appraisal of stressors as challenging or hindering. Most literature focuses on applying the challengehindrance stressor framework to performance outcomes. In contrast, the current study applies the framework to work-family outcomes while also examining the potential moderating effects of individual learning goal orientation (LGO). Ninety-seven participants completed online surveys through Amazon's MTurk. Analyses revealed a positive relationship between challenge-related stressors and work-family conflict (WFC) as well as a positive relationship between hindrancerelated stressors and WFC. Furthermore, hindrance-related stressors and LGO interacted to predict WFC. The interaction indicated that the positive relationship between hindrance-related stressors and WFC was stronger at higher levels of LGO. Additionally, a positive relationship was found between LGO and labeling a higher number of ambiguous stressors as challengerelated. This study builds on prior literature by examining individual characteristics that may influence the effects of the challenge-hindrance stressor framework as well as identifying the importance of applying the framework to work-family outcomes. Future research calls for examining the influence of time in the challenge-hindrance stressor framework as well as examining the way individuals with low and high LGO cope differently with stressors and how coping strategies could influence work-family outcomes.

- Characterization of calpain activity in response to microplastic exposure in Donax variabilis.
- Author
- Schroeder, Hans Erik
- Abstract/Description

Coquina clams (Donax variabilis) are small multicolored bivalve mollusks that inhabit the intertidal zones of various southeastern beaches along the eastern coast of the United States where they are in great abundance and an essential part of the beach ecosystem. Because they are filter-feeders that are exposed to environmental hazards, Donax variabilis populations are a sign of the beach's ecological health.

Show moreCoquina clams (Donax variabilis) are small multicolored bivalve mollusks that inhabit the intertidal zones of various southeastern beaches along the eastern coast of the United States where they are in great abundance and an essential part of the beach ecosystem. Because they are filter-feeders that are exposed to environmental hazards, Donax variabilis populations are a sign of the beach's ecological health. Potentially, this mollusk may be effective as a "canary in a coal mine" if biological changes are easily measurable that may be sensitive to important environmental changes. One such mechanism are the calpains. Calpains are Ca2+-dependent cysteine proteases that are expressed in nearly all eukaryotes, but have rarely been studied in invertebrates like the Coquina clam. It is well established that calpains are essential to cellular homeostasis and have been implicated in a multitude of cellular functions, such as apoptosis and cellular stress. In recent years, microplastics, plastic particles that range in size but are less than 5mm, have become a serious hazard to the environment. Accumulation of microplastics have only recently been recognized to be harmful to marine organisms that ingest them and cause tissue damage on a cellular and subcellular level that may alter calpain activity. Although Coquina clams are in great abundance on the beaches and their ecological patterns have been studied thoroughly, the cellular and subcellular processes of the Coquina clam have not been studied extensively. Specifically, it is not understood how calpains function under normal conditions or how these molecules would be affected due to large ecological impacts in the form of contaminants like microplastics. It is our contention that Coquina clams can be used as a bioindicator of healthy beaches and aid in assessing the presence or absence of pollutants such as microplastics that can occur in the ecosystem, using cellular and subcellular processing by calpains as a measure.

- Neltner, Tyler Joseph
- Abstract/Description
-
The ability to train unilaterally and experience contralateral strength gains, a phenomenon known as cross-education, has been well documented in the lower extremity. Additionally, short-term training of one to two weeks has shown neural adaptations in strength. The purpose of this study is to examine the effects of a short-term cross-education strength-training program on contralateral shoulder strength.

Additionally, short-term training of one to two weeks has shown neural adaptations in strength. The purpose of this study is to examine the effects of a short-term cross-education strength-training program on contralateral shoulder strength. Twenty-seven healthy college students (age: 21.37 ± 2.02 years; height: 167.85 ± 7.63cm; mass: 74.42 ± 16.73kg) were randomly assigned to either an experimental (n = 13) or control group (n = 14). Participants were tested at each of three speeds (60, 180, and 300d/s), completing six repetitions of shoulder internal/external rotation. The experimental group underwent right arm unilateral training two times a week for the next two weeks. No analysis could be done on 300d/s due to no load range data. Therefore, a 2x2x2x2 (time x arm x speed x group) ANOVA revealed no significant interactions by group; however, there were main effects of time and arm. Peak torque was significantly greater in the right arm and at 60d/s, and average power was significantly greater in the right arm and at 180d/s. Shortterm cross education training showed no increase in contralateral shoulder strength.

- The effects of box height on drop jump performance.
- Author
- Addie, Cameron Douglas
- Abstract/Description
-
Depth jumps (DJ) are commonly implemented in plyometric training programs in an attempt to enhance lower extremity jump performance. However, it is unknown how different box heights affect jump height (JH) and ground contact time (GCT). PURPOSE: The purpose of this study was to assess jump heights and ground contact time of depth jumps from various box heights. METHODS: Twenty college students who engaged in plyometric training (M = 13, F = 7; age: 22.80 ± 2.69 yr, height: 175.65 ± 11.81 cm,...
Show moreDepth jumps (DJ) are commonly implemented in plyometric training programs in an attempt to enhance lower extremity jump performance. However, it is unknown how different box heights affect jump height (JH) and ground contact time (GCT). PURPOSE: The purpose of this study was to assess jump heights and ground contact time of depth jumps from various box heights. METHODS: Twenty college students who engaged in plyometric training (M = 13, F = 7; age: 22.80 ± 2.69 yr, height: 175.65 ± 11.81 cm, mass: 78.32 ± 13.50 kg) performed DJs from 30 cm (DJ30), 45 cm (DJ45), 60 cm (DJ60), 76 cm (DJ76), and 91 cm (DJ91). A 16 camera Vicon system was used to track reflective markers bilaterally to calculate JH (ASIS, PSIS), while a Kistler force plate was used to record GCT. JH and GCT were compared using a 2x5 (sex x box height) repeated measures ANOVA. RESULTS: There was no interaction but there was a main effect for sex where both JH (M>F) and GCT (F>M) showed a significant M bias. There was no box height main effect for JH DJ30 (.4934 ± .1126 m), DJ45 (.5003 ± .1134m), DJ60 (.4936 ± .1195 m), DJ76 (.4957 ± .1105 m), DJ91 (.4783 ± .1162 m) but there was for GCT where DJ30 (.3584 ± .0971 s), DJ45 (.3605 ± .10528 s) and DJ 60 (.3723 ± .1049) were not significantly different from each other but were all less than DJ76 (.3962 ± .1161) and DJ91 (.4209 ± .1154). CONCLUSIONS: Increasing box height beyond 60cm increased GCT but did not affect JH. Therefore, practitioners designing plyometric training programs that implement DJs in order to increase JH may stop at a box height of 60cm. This would keep GCT minimal which might play a role in other power and speed events.

- Effects of light and salinity on post-bleaching recovery in the jellyfish Cassiopea SP.
- Author
- Maloney, Megan Elizabeth
- Abstract/Description
-
Cassiopea sp. was collected from the Florida Keys and used to study the effects of environmental conditions after a warming event to induce photobleaching. Jellyfish were bleached by elevating the temperature to 33 °C. Wet weight, bell diameter, pulse frequency, zooxanthellae, protein, carbohydrate, and lipid were measured in bleached and non-bleached individuals held under a salinity of 30 g kg-1, 35 g kg-1, and 40 g kg-1, and either full light exposure or partial shading after eight weeks....

There were no statistical differences between any of the treatment means for bleaching, light, or salinity level; however, biological parameters indicated salinity could potentially cause a change in the physical and metabolic properties of the jellyfish. An initial sample indicated that Cassiopea sp. in this study may not have fully bleached at 33 °C; that outcome, together with the bleached group recovering to non-bleached levels, indicates Cassiopea sp. is resilient/resistant to some thermal increase.

Invasive species are non-native species that pose a threat to current biodiversity, alter the community structure, and disrupt the ecosystem. Invasive species of high concern are in the genus Pterois, commonly known as lionfish. These species were introduced to the Western Atlantic Ocean and today can be found all throughout the Northern Gulf of Mexico. Lionfish have been recently observed in estuaries even though they are not traditionally euryhaline species. However, confirming presence of...
Show moreInvasive species are non-native species that pose a threat to current biodiversity, alter the community structure, and disrupt the ecosystem. Invasive species of high concern are in the genus Pterois, commonly known as lionfish. These species were introduced to the Western Atlantic Ocean and today can be found all throughout the Northern Gulf of Mexico. Lionfish have been recently observed in estuaries even though they are not traditionally euryhaline species. However, confirming presence of a particular fish in estuarine environments can be costly in terms of resources and can be difficult due to environmental conditions and fishing methods required. The purpose of this study was to detect the presence of lionfish throughout river systems and estuarine environments of the Northern Gulf Coast using environmental DNA (eDNA). Six locations in the Northern Gulf of Mexico were sampled seasonally: The Mobile Delta, Escambia Bay, Blackwater Bay, Perdido Bay, Pensacola Bay and Perdido Key. Results show that lionfish were present in each of the sampled estuarine environments and river systems in the Northern Gulf of Mexico during the course of this study. This information can be used to aid in management techniques for estuaries that are home to commercially and ecologically important species.

Show moreGravestones from the Mare Island Naval Cemetery were recorded, compared, and analyzed for evidence of a connection between the choice of gravestone style, material, or location with five aspects of identity: age, sex, occupation, socioeconomic status, and ethnicity. The cemetery is separated into six sections, labeled A, B, C, D, E, and F. Data on gravestone style, material, and location were collected during two public cultural resources surveys in collaboration with the City of Vallejo. Historical research supplemented the data gathered on site. Data was gathered for all 903 gravestones within the cemetery. Analysis of these data included a spatial analysis of maps pertaining to the five aspects of identity and statistical analysis using chi-square and Cramer's V to determine the level of association between two variables. The spatial analysis indicates that individuals with a monthly income of $90.00 or more as well as individuals of a higher ranking occupation were located at the top of the hill in the cemetery in Section A and the top of Section C. Section A, at the top of the hill, also contained the most youth (age 17 and younger). These data suggest these areas were reserved for high ranking or upper-class individuals and their families. Statistical analysis indicated that none of the aspects of identity had a strong influence on the choice of gravestone material or style, which suggests an equality in death regarding style and material.

Show moreAnthropogenic disturbances, such as habitat fragmentation, can disrupt seagrass microhabitat availability and increase the availability of seagrass bed edges. This research focused on microhabitat selection and substrate use of seagrass-associated invertebrates in St. Joseph Bay, Florida, emphasizing edge effects and habitat selection of the sea urchin Lytechinus variegatus. Monthly field surveys were conducted in Thalassia testudinum beds in St. Joseph Bay, Florida, in 2017 and 2018. Microhabitat use pertained to edge effects and substrate use pertained to usage of pen shells, mussels, and seagrass by sea urchins. Settlement plates were deployed to analyze the importance of the semi-infaunal bivalve Atrina rigida (pen shells) for sessile invertebrates in seagrass habitat. Results show that L. variegatus prefers interior seagrass habitat compared to edge habitat, whereas other epibenthic macrofauna displayed mixed results for microhabitat selection. Sea urchins displayed a preference for Modiolus americanus mussel substrate. A sea urchin mortality event occurred during a cold spell. Results also suggest that sessile fauna utilize A. rigida as hard substrate due to a lack of alternative options. The results have implications for seagrass overgrazing events, seagrass-associated faunal responses to climate change, and habitat destruction.

Show moreThis thesis examines sexual connotations of the garden space in Hawthorne's "Rappaccini's Daughter." Its focus is the sexuality of the protagonist Beatrice within the traditional patriarchal family unit. Her sexuality is a fixation for her biological father and her courter-turned-brother, and is reflected in the poisonous flowers that surround her. She, too, is envenomed from having cultivated the plants. As a result, they come to take on a familial relation. This shared toxicity shows the dangerous nature of feminine sexuality. Beatrice and the plants have provocatively sexual beauty on display for the men in the garden to fixate on, fear, and punish, manifesting in incest. This thesis reveals parallels between Beatrice's experiences in the garden and the biblical Eden concerning sexual awareness of the physical body. This inverted Eden makes its few inhabitants, including Beatrice's sister-plants, into a quasi-family. It becomes the stage where incestual taboos and their repercussions play out. Ultimately, Hawthorne's text is a cautionary tale for when feminine beauty is flaunted and male control turns perverse.

In this study, I examine the possible causes behind a greater-than national level infant mortality rate for two of the counties and why one of these counties possesses a much lower rate. Through semi-structured interviews and geospatial analysis, I examine indicators of health that contribute to higher infant mortality. A theoretical lens of structural violence, habitus, and structural determinants of health brings attention to the invisible violence that is causing infant death within Northwest Florida. Research questions include the following: What factors are contributing to infant mortality in NWFL? How might health care access and literacy contribute to poor infant health outcomes? What interventions could help improve health literacy and health care access for those experiencing significant barriers to care in NWFL? Indicators that were found as possible contributors to higher infant mortality rates were poor health literacy, poor access to resources like health care, transportation, education, and poverty.

Show moreSand fences have become a standard use in beach management practices, and the relationship between sand fences, vegetation, and dune development has been widely studied. The New Jersey coastline has been the location for an extensive amount of sand fence studies and has provided a standard used by beach management along various coasts. However, the Florida Panhandle contains a different coastal environment to that of New Jersey but has not received as much focus. This study looks to assess the relationship between local variables and fence configuration. The study will be conducted on The University of West Florida (UWF) beach property. The study site contained fifteen sand fences in five different configurations to monitor sand accumulation. Equipment used will include a weather station, anemometers, pre-constructed sand fences, and erosion pins. Once data has been collected, statistical analysis of trapping efficiency will occur. This study looks to expand the knowledge on sand fences by providing a narrow focus on the trapping abilities of various sand fence configurations. An expected outcome of the study is to gain a better understanding of the trapping efficiency of fence configurations in relation to local variables.

Show moreDelineation of relict terraces along the Northwest Florida coast can facilitate investigation of soil development within the Gulf of Mexico (GOM) coastal plain. Previous work to define terraces has primarily relied on topographic studies with little consensus on the number and extent of terraces. Research investigating soil development within the GOM coastal plain is also limited. The present study utilizes Geographic Information Systems (GIS) and a LiDAR derived Digital Elevation Model (DEM) to apply a Surface Classification Model (SCM) for selection of terrace surfaces based on slope and surface roughness. The SCM output was analyzed for peaks in pixel count by elevation. Five terraces were defined between the following elevation ranges: 0-3.6 m, 4-9 m, 16-27 m, 29.5-51 m, and 57-64 m. Soil properties known to exhibit time related trends were analyzed across the delineated terraces. At increasing elevations, and presumably ages, soils exhibited a thickening of both the solum and Bt horizon, an increase in clay content, and a decrease in organic matter content. Bt horizons were observed at increasingly greater depths, with the exception of terrace 5, which was at shallower depth. Likely due to erosion associated with the high elevation and greater exposure of the surface.

World War I ensured aviation would remain an important aspect of U.S. naval warfare and led to an increased influx of prospective aviation cadets at NAS Pensacola. Subsequent decades of training led to hundreds of training accidents and the loss of naval aircraft in the waters off Pensacola, Florida. Two F8F Bearcat wreck sites are discussed here, including the methods involved in aircraft investigation and the historical documents referenced for their identification. Utilizing photogrammetric modeling techniques, the author tests the applicability of photogrammetry as an in situ site-monitoring tool.

Show moreIn contrast to mammals, the fish CNS produces new neurons throughout life and, following injury, neurons fully regenerate and function is restored. Understanding how and why persistent neurogenesis and CNS regeneration occur in fish, but not in mammals, is crucial for developing the ability to treat CNS injury and disease in humans. The zebrafish has a relatively simple early developmental period compared with many marine fish species and does not represent the full diversity of developmental mechanisms among vertebrates. Therefore, our objective is to develop the pinfish, Lagodon rhomboides, as a marine fish laboratory model that will improve our understanding of the complex factors that affect retinal neurogenesis. In early experiments, the Rhodopsin gene, a critical visual pigment in rod photoreceptors, was cloned from the pinfish retina and sequenced. Next generation sequencing was used to sequence the entire pinfish genome, which will be gradually assembled. Additionally, pinfish have been maintained in fiberglass tanks equipped to control light cycle, temperature, and other environmental factors that usually induce spawning in marine fish. Manipulating these factors to simulate the ideal conditions for the spawning will allow this project to be carried out throughout the year. Spawning has been induced, and larvae have been raised up to metamorphosis. Early data suggest that salinity may influence the timing of metamorphosis. In lower salinity, the onset of metamorphosis was observed at 9 days. However, in higher salinity, metamorphosis was not observed up to 17 days post hatch. The next step is to determine whether salinity affects timing xi of metamorphosis. Subsequently, we will determine the timing of photoreceptor genesis during development.

Following initial LAS, degenerative changes have been found in over 70% of participants for extended periods of time. With the aforementioned degenerative changes typically come alterations in movement patterns, muscle activation patterns, and arthrokinematics. The current study aimed to investigate the effects of LAS history on neuromuscular control during a soccer specific jump-landing task and to illustrate the impact of limb (injured vs. non-injured) on neuromuscular control during a soccer specific jump-landing task in female adolescent athletes (n = 14, age = 16 ± 1.0 yr). A control group (n = 7) and a group designated as the "ankle sprain" group (n = 7) were used. The injured ankles in the ankle sprain group and the dominant limbs of the control group were labeled "affected," while the uninjured limbs of the ankle sprain group and the non-dominant limbs of the control group were labeled "unaffected." Electromyography (EMG) sensors were placed on 6 lower-limb muscles of each participant bilaterally, totaling 12 sensors per participant -- Lateral Gastrocnemius (LG), Peroneus Longus (PL), Tibialis Anterior (TA), Vastus Lateralis (VL), Vastus Medialis (VM), and Biceps Femoris (BF). Each participant completed a 5-minute low-to-moderate intensity warm-up on a cycler ergometer, then completed 10 soccer-header jump-landing trials. There were no significant limb by group interactions (p > 0.05) or group main effects (p > 0.05) found in the current study. Pre-landing data showed significant limb main effects for the vi standard deviation (SD) of the unaffected PL (p = 0.017) and the affected VL (p = 0.048). Furthermore, significant limb main effects were discovered for the COV of pre-landing muscle activation for the PL (p = 0.043), LG (p = 0.049), and VL (p = 0.048). During the post-landing period, significant limb main effects were recorded for the average activation (p = 0.001) and SD (p = 0.003) of the PL and the COV of the VL (p = 0.038). Reduced activation of the nondominant limbs illustrated increased neuromuscular control in the distal musculature (PL), while the proximal musculature (VL) demonstrated reduced neuromuscular control on the unaffected limbs. The current study discovered that limb dominance was a more prominent factor in altered lower-leg neuromuscular control compared to ankle injury history. Limb differences were mostlikely the result of the sport-specific demands placed on the dominant and non-dominant limbs during soccer, which elicited increased muscular responses of the non-dominant limb during jump-landing tasks.

- Abstract/Description

This research followed Oglala Lakota Alex White Plume, whom I met in 1992, tracing issues of sovereignty and unjust U.S. policies against Native Americans. White Plume sought to become America's first industrial hemp farmer, planting in 2000, 2001, and 2002. He was supported by tribal law, but received a federal injunction prohibiting hemp farming, in place until 2016. Using ethnographic field methods, I examined his case through participant observation, interviews, talks, and photographs,...

White Plume sought to become America's first industrial hemp farmer, planting in 2000, 2001, and 2002. He was supported by tribal law, but received a federal injunction prohibiting hemp farming, in place until 2016. Using ethnographic field methods, I examined his case through participant observation, interviews, talks, and photographs, documenting the 2018 White Plume Victory Celebration and Annual Lakota Pony Races on the Pine Ridge Reservation and answered: How is sovereignty and resilience conceptualized and interpreted by White Plume and the Lakota? How are the Lakota resilient in overcoming historic oppression to enrich their cultural heritage? What role does the National Park Service play in federal-tribal relations within a resiliency context? My findings define the Resilient Warrior and document methods of resiliency against historic oppression and social injustice. These methods include sharing cultural traditions, language revitalization, and asserting sovereignty through practices including plant gathering and hemp farming. I also document evolving NPS policies that expand tribal programs in recognizing and honoring Native Americans and seek to braid Native American and U.S. histories.

Anthropogenic influence from urbanization affects the health of estuaries all over the world. Three urbanized bayous in the Pensacola Bay System (Bayou Texar, Bayou Chico, and Bayou Grande) are estuarine systems affected by their surrounding watersheds. Land use in Bayou Texar's watershed is mainly residential properties. Bayou Chico's lower watershed is mainly industrial, while the upper watershed is residential.

Show moreAnthropogenic influence from urbanization affects the health of estuaries all over the world. Three urbanized bayous in the Pensacola Bay System (Bayou Texar, Bayou Chico, and Bayou Grande) are estuarine systems affected by their surrounding watersheds. Land use in Bayou Texar's watershed is mainly residential properties. Bayou Chico's lower watershed is mainly industrial, while the upper watershed is residential. In Bayou Grande, one shoreline is home to the Naval Air Station, Pensacola, and the other shoreline is residential. This study examined spatial and temporal variability of water quality in these systems. Comparison of bimonthly samples with historical data provided a perspective of how water quality has changed and responded to urbanization in these systems. High nutrients and chlorophyll were observed in Bayou Chico and Bayou Texar. Seasonal variation in nutrients was smaller than expected. Mixing curves of nutrients showed non-conservative mixing reflecting spatially distributed sources and sinks. DIN to DIP ratios showed that phosphorus was the limiting nutrient in Bayous Chico and Texar, whereas in Bayou Grande there was a seasonal change in nutrient limitation from nitrogen to phosphorus. Warm temperatures, and high light availability, make these urban bayous susceptible to eutrophication.
