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. However, the data did reveal some apparent self-selection of the...
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 moreThe Seamen's Cemetery is a section of St. Joseph's Cemetery dedicated mostly to red snapper fishermen of Pensacola, Florida, and reflects aspects of those men. The cemetery provides a sample of names which allowed for an in-depth analysis of the fishermen. Organizations that contributed to the formation of the cemetery and the fishermen themselves are investigated through both historical documentation and the physical components of the cemetery. The Pensacola Fishermen's Benevolent Association, a fishermen's union, was the most active organization contributing to the cemetery. Working in the interests of the fishermen, actions of the union indicated that the fishermen particularly valued their income, reputation in society, and burials. During the course of this thesis, conservation efforts restored the cemetery closer to its original appearance. These conservation efforts allowed the author to explore how the cemetery expressed the values of the fishermen concerning burials of their comrades, specifically the values of having a body to bury and equality in remembrance. Furthermore, the fishermen of the cemetery were analyzed through personal documentation to understand their life, ethnic composition, and death of the red snapper fishermen of Pensacola.

- Side channel attacks and device vulnerabilities: methodologies of attack and prevention.
- Author
- Easley, Ronda Rae
- Abstract/Description

Side channel attacks are methods by which the encrypted data on a device or network can be obtained through observation and manipulation of the unintended outputs of the device such as power or electromagnetic radiation fluctuations, timing variances, or even discrepancies in sound or acoustic levels while the device is processing cryptographic functions. These attacks have become more prevalent as internet-of-things (IoT) devices have become more commonplace. Often the priorities in the...
Show moreSide channel attacks are methods by which the encrypted data on a device or network can be obtained through observation and manipulation of the unintended outputs of the device such as power or electromagnetic radiation fluctuations, timing variances, or even discrepancies in sound or acoustic levels while the device is processing cryptographic functions. These attacks have become more prevalent as internet-of-things (IoT) devices have become more commonplace. Often the priorities in the manufacture of such devices are compact size and low power consumption. Meeting these design parameters leads builders to insert less security measures into both the device hardware and the encryption software. Prior research details both the attack methods and countermeasure strategies that can be deployed during the design phase to offer higher security to the device. The research within this thesis defines and details the known methods of side channel attacks and identifies the intrinsic vulnerabilities of specific device types and encryption methods. This work further offers a tabular representation of the research which can be utilized by builders to identify vulnerabilities and recognize appropriate countermeasures.

- Thermal tolerances and preferences of adolescent Louisiana alligators (Alligator mississippiensis).

With 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.

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.

In this paper, we are going to show the existence of Ramanujan graphs among different classes of graphs. The main areas of research surrounding these graphs consider their classification and existence for different degrees and orders. The focus of this body of work is to observe different classes of graphs, and to see if they fit the definition of Ramanujan graph under certain conditions.

The main areas of research surrounding these graphs consider their classification and existence for different degrees and orders. The focus of this body of work is to observe different classes of graphs, and to see if they fit the definition of Ramanujan graph under certain conditions. First, we examine whether all strongly regular graphs are Ramanujan. Then, different restrictions are placed on the parameters of strongly regular graphs, and we explore whether those yield Ramanujan graphs. Some other results related to graph factors and some special graphs are observed as well.

Show moreThis research effort develops a framework capable of cross-platform integration to develop a Structure from Motion 3-D model using a team of autonomous small Unmanned Aerial Systems (sUAS). In the development of this framework, a simulation environment with a house is used as an example of a simulated mission. The framework is composed of two major goals to accomplish this. The 3-D reconstruction software is evaluated with two separate datasets for optimization with the intent to reduce the computational time required to build a model that is usable. One dataset is a lab controlled environment for initial observations and the other dataset is of a real world environment for applicability to hardware implementation. The priority is usability of the model and speed in reconstruction. During this evaluation, four parameters are manipulated in software for evaluation quality, image number, camera angle, and multi-view formation. An optimum set of parameters is suggested for the framework to work successfully. The Distributed Behavior Model is based on the entropy of the system where distance between the sUAS is the variable used. As the distance between each sUAS decreases, the entropy of the system also decreases. An investigation into the Distributed Model Behaviour is conducted with the intent to have a robust and scalable algorithm capable of navigating the sUAS to the desired objective. Parameters used for evaluation are (i) minimum distance between sUAS and (ii) entropy threshold. Simulations are run with 3, 5, 7, 9, 15 and 20 sUAS to confirm scalability, robustness, and threshold values. A minimum distance setting is confirmed, and a function for scaling the threshold value is determined. Finally, these two portions are combined in simulation to demonstrate the framework operability and evaluate the completeness and speed of the reconstructed model. The simulations show that the framework operates and is capable of generating complete models as desired autonomously.

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 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 moreProbate records, documents including wills and estate inventories and auctions, are excellent tools for historical archaeologists who want to better understand the material possessions of past peoples. Probate and archaeological data are particularly amenable to comparison because they both quantify material culture. This thesis compares a sample of 76 16th-century Spanish probate records (both inventories and auctions) compiled in Spanish America to the archaeological assemblages of the 1559-1561 Luna Settlement site and Emanuel Point I (EPI) Shipwreck in Pensacola, Florida excavated by the University of West Florida. The probate records of a variety of Spanish individuals were chosen to reflect the types of people that would have inhabited the site including soldiers, sailors, carpenters, blacksmiths, doctors, artisans, women, etc. This work involves the transcription and translation of historical Spanish documents and the creation of a Probate Inventory Database and an artifact database. The primary goal is to demonstrate the utility of synthesizing material culture data from both the documentary and archaeological records as well as provide an analysis of the similarities and differences between these data sources using the Luna Site and EPI as case studies. An emphasis is made on the idea of "personal property" in 16th-century Spanish America. This project is a model for synthesizing quantitative data from documentary and archaeological sources.

Show morePopulations from two historic cemeteries in Pensacola, Florida were researched, analyzed, and compared through the use of archival and site survey records in order to understand connections between causes of death, ages at death, and socioeconomic status (SES). A total of 1,267 individuals were analyzed within this research (404 from AME Zion and 863 from the Escambia County Poor Farm) to answer 1) how the socioeconomic status (SES) of a selection of a population connects to their eventual cause of death and age at death; and 2), how SES is or is not reflected in the burial practices evident through extant surface material at cemetery site(s). The goal of this research was to better understand how the life experiences of people in the past affected their representations in death. Initial analysis of the overall populations (AME Zion n=404; Poor Farm n=863) showed higher rates of infant deaths and males at the Poor Farm than was seen in the AME Zion Pre1970 population sample of all ages. For these full samples, susceptibility to the most frequent causes of death categories (Illness and Disease) were the same at each site. With these similar levels however, individuals at neither site were living substantially longer than the other even when individuals at the Poor Farm had a significantly average SES. Analysis of the cause of death and age at death analysis samples (AME Zion n=240; Poor Farm n=419) as well as analysis of the SES subsamples (AME Zion n=133; Poor Farm n=408) highlighted sex and SES differences between the sites where the Poor Farm had a higher frequency of males and higher wages, on average. Conclusions found no connection between SES and the existence or absence of extant surface materials at AME Zion or the Poor Farm but brought to light the possibility of other cultural factors such as church affiliations and burial associations.

In Edmund Spenser's The Faerie Queene, scenes of armament and disarmament allegorize the way that idealized and degenerate forms of masculinity are forged. Armor, in Spenser, is less a physical than a psychological shield. Donned at the wrong time, the knights become cruel, untrustworthy, and apathetic. Removed at inappropriate junctures, they descend into lust, avarice, and gluttony. Spenser's epic models the self-fashioning by which gentleman could come to embody the harmony of Venus and...
Show moreIn Edmund Spenser's The Faerie Queene, scenes of armament and disarmament allegorize the way that idealized and degenerate forms of masculinity are forged. Armor, in Spenser, is less a physical than a psychological shield. Donned at the wrong time, the knights become cruel, untrustworthy, and apathetic. Removed at inappropriate junctures, they descend into lust, avarice, and gluttony. Spenser's epic models the self-fashioning by which gentleman could come to embody the harmony of Venus and Mars. Empedocles' principle of love and war--the idea that eros and strife must come together for the generation of life to occur--is central to Spenser's idea of exemplary masculinity as well as to his political and artistic vision of harmony. The epic models a paradigm of courtly masculinity that places a premium on intense emotional relationships between men, even as it divorces eros from the realms of martial honor and patriarchalism. Since Spenser's vision of self-fashioned masculinity depends upon his understanding of court culture and the woman presiding over it, I conclude my thesis by looking at the epic's critique of Elizabeth I's use of romantic tropes and erotic pageantry

Show moreWooden casks served as essential tools for economic development for thousands of years by storing and transporting various commodities. Though they no longer play as significant of a role for commerce in the modern era, their utility is still remembered because of their long-lasting reign of use. Historians and archaeologists alike study both casks as well as the individuals who make them (coopers) to further understand the significance each held as contributors toward economic growth. Archaeologists have recovered numerous types of wooden casks from across the globe, with each discovery shedding light on the cultural significance held by different cask types during different eras. Though archaeologists have yet to recover a fully intact cask from any of the archaeological sites affiliated with the Tristan de Luna expedition of 1559, one of the site's artifact assemblages (the Emanuel Point II's (EPII)) contains a collection of objects identified as wooden cask components. An analysis of these components contributes toward the identification of cask types within the EPII artifact assemblage, thereby shedding light on the types of casks utilized by 16th-century Spanish colonists.

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 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.

Show moreAtypical antipsychotics (AAPs) are a class of drug used to treat several mental diseases like bipolar disorder, obsessive-compulsive disorder, and schizophrenia. However, these substances are also known to cause a rare, yet severe and sometimes fatal syndrome known as neutropenia. Neutropenia (and its more acute form, agranulocytosis) is characterized by a significant decrease in an individual's circulating neutrophils--the most abundant white blood cell. Neutrophils are essential for proper innate immunity, and depletion can result in higher risk of developing life-threatening illnesses. How atypical antipsychotics induce neutropenia is not well-understood, though research is ongoing. In this study, we aim to characterize the effects of four AAPs--clozapine, olanzapine, quetiapine and aripiprazole--on PLB-985 cell viability, as assessed by the XTT Cell Viability Assay. We found that only aripiprazole is able to significantly decrease dPLB-985 cell viability after 48-hour treatment. We hypothesized that aripiprazole's negative effect on cell viability is through its unique mechanism of action as a partial dopamine agonist; however, our results suggest that aripiprazole's effects are independent of dopamine receptor agonism.

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.

Show moreUtility grid companies are currently facing many challenges. These challenges include energy management, efficiency, and power quality issues. It is well known that improving power systems' management, control, and quality results in better economic benefits, increased electronic device lifetime, and reduced power interruptions, leading to the satisfaction of utility and consumer. Many research efforts were done in the past decades focusing on power systems control, quality, and management. The need for more green energy resources has inspired these researchers to find ways to integrate renewable energy resources into the grid. The current grid is facing issues due to a number of reasons such as increased Distributed Energy Resources (DERs) types and number, increased loads' types and number, and the increased distance between the DERs, loads, and the grid. The study of this thesis aims at finding creative energy management and control solutions through observing and understanding the characteristics of the utility grid and implement these solutions in a simulation software called MATLAB/Simulink. Consensus-based control will be implemented in a hybrid generation microgrid which will support the grid and work on restoring voltage and frequency levels with optimum power sharing between the DER.

A wide range of environmental pressures and anthropogenic stressors, such as overfishing, climate change, and coastal development, have negatively affected fish communities in the Gulf of Mexico, specifically reef fish inhabiting natural or artificial reefs. Fish communities in the Gulf of Mexico vary both spatially and temporally due to movements in the water column, migrations, and environmental pressures making conventional survey sampling challenging to perform.

Show moreA wide range of environmental pressures and anthropogenic stressors, such as overfishing, climate change, and coastal development, have negatively affected fish communities in the Gulf of Mexico, specifically reef fish inhabiting natural or artificial reefs. Fish communities in the Gulf of Mexico vary both spatially and temporally due to movements in the water column, migrations, and environmental pressures making conventional survey sampling challenging to perform. Conventional methods can often be costly, time-consuming and invasive to the target organism. A possible resolution to overcome these challenges to inventory reef fish species lies with environmental DNA (eDNA) metabarcoding. Water samples were collected from artificial and natural reefs in the Gulf of Mexico. The 12s rRNA mitochondrial gene was amplified using elasmobranch and MiFish primers. Only elasmobranch primers were able to provide valuable reads. Amplicon libraries generated by PCR were sequenced using Illumina HiSeq. Environmental DNA metabarcoding revealed 4 reef-associated species out of 12 detected species, the Rough scad (Trachurus lathami), Sand diver (Synodus intermedius), Pearly razorfish (Xyrichtys novacula) and the invasive Lionfish (Pterois spp.). Fish species detections across nine sites were grouped by habitat and IUCN status. Surface and benthic fish detections were grouped by temperature and salinity. A generalized linear model and linear regression were used to test for correlation. This project demonstrates the utility of eDNA and metabarcoding as a valuable tool for characterization of reef fish species in the Gulf of Mexico.

- Growing pains: investigating satellite tag epoxy attachments on juvenile turtles.
- Author
- Vidal, Alexander
- Abstract/Description
-
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. Tracking durations can be brief and limited by technical failures....
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.
