This research identifies the individuals who perished as a result of the 1882 yellow fever epidemic in Pensacola, Florida, locates the graves of these individuals, and determines if there were any changes in mortuary practices as a result of the epidemic. Through use of the Pensacola Semi-Weekly Commercial and a document commissioned by the Board of Health, the 197 yellow fever victims reported to the Board of Health are identified, including an additional 20 individuals who likely died...
Show moreThis research identifies the individuals who perished as a result of the 1882 yellow fever epidemic in Pensacola, Florida, locates the graves of these individuals, and determines if there were any changes in mortuary practices as a result of the epidemic. Through use of the Pensacola Semi-Weekly Commercial and a document commissioned by the Board of Health, the 197 yellow fever victims reported to the Board of Health are identified, including an additional 20 individuals who likely died outside the city limits. Cemetery records and surveys were used to locate these individuals within a cemetery. The results were analyzed using two different approaches: (1) examining the percentage of individuals found in a cemetery and (2) analyzing the elapsed time between death and burial. Based on the small percentage of victims located in a cemetery and the rapidity with which a body was buried following death, this study shows that burial practices in Pensacola were altered as a result of the epidemic.

- An analysis of pivot strategies to maintain sparsity in the LU decomposition of IPDG method applied to the Helmholtz Equation.
- Author
- Severance, Ryan Samuel
- Abstract/Description
-
In recent years, the interior penalty discontinuous Galerkin (IPDG) method has appeared in literature as an efficient and stable method for approximating the Helmholtz equation. LU decomposition has then been used to solve the linear system formed by the IPDG method. However, research has shown that the LU decomposition causes fill-in of the sparse structure of the global matrix. This talk addresses the application of several pivot strategies to the global matrix before the LU decomposition,...

LU decomposition has then been used to solve the linear system formed by the IPDG method. However, research has shown that the LU decomposition causes fill-in of the sparse structure of the global matrix. This talk addresses the application of several pivot strategies to the global matrix before the LU decomposition, in order to assess if this fill-in can be reduced. Numerical experiments are presented to demonstrate that pivot strategies did reduce fill-in when applying the LU decomposition.

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

Show moreAccumulation of oxidative damage has been implicated in numerous diseases bringing antioxidant investigations and plant phenolics to the forefront of medicinal research. The species Dioscorea bulbifera has been used in both traditional and modern medicinal systems and has good overall antioxidant capacity. Yet little work has been done to assess which chemical components may contribute to this action. The goals of this study were to investigate the antioxidant activity of individual phenolic compounds in the plant D. bulbifera; to compare the in vitro antioxidant assays with human cell studies; for this information to contribute to future investigations in treating human disease. Methanolic extracts of the D. bulbifera bulbils were analyzed using HPLC-MS/MS and NMR. Positively identified compounds were used for in vitro antioxidant assays (Ferric Reducing Antioxidant Power (FRAP), iron chelation, and Oxygen Radical Absorbance Capacity (ORAC), followed by human cell assays. Several phenolic species were tentatively identified. (+)-catechin was positively identified and used for further testing. In vitro assays showed potential for electron transfer antioxidant activity but not iron chelation. The hydrogen transfer mechanisms could not be assessed due to assay complications. Cell assays also suffered complications rendering them inconclusive.

Show moreAfter 1704 attacks by the British and their Native American allies, some Apalachee fled their homeland to French Mobile, Spanish Pensacola, and Creek areas. Primary research indicates that those Apalachee who chose to ally politically with either the French or Spanish maintained social connections with both nations as well as the Lower Creek, and through the Creek enjoyed an economic connection with the British. At the same time, by consistently referring to the groups as Apalachee, documents imply some maintenance of Apalachee tradition during the eighteenth century. Comparisons of ten tightly-dated ceramic assemblages quantify material shifts through time and space and augment the historical record. This synthesis illustrates that Apalachee refugees had sufficient resources to play Europeans against each other yet adopted new ceramic traditions. Political and material maneuvering thus allowed them to maintain their social identity.

Show moreThe Lord of the Rings, Harry Potter, Star Wars, and Star Trek are but a few modern mythologies that have become woven into the tapestry of our western culture. We have not only embedded these modern myths into our culture, but many people know these modern mythical cultures better than they do their own mundane, "real" culture. Although this study is unconventional in the field of anthropology, this thesis analyzes J.R.R. Tolkien's work of The Hobbit and The Lord of the Rings. The purpose of this thesis is to provide the evidence that fictional cultures are reflections of western ideals; that fictions can be studied like any other non-fictional culture using anthropological approaches; and that modern fictions are modern mythologies. In this thesis, the famous The Lord of the Rings series is analyzed using the anthropologist Claude Levi-Strauss's structural perspective and his model of defining the meaning of myth to demonstrate how Tolkien's The Lord of the Rings canon can be successfully analyzed in the same fashion.

Show moreThis thesis investigates the domestic components at Arcadia Mill (1817-1855) using historical and archaeological data to develop a descriptive model of the multiethnic, antebellum community. The archaeological data set results from two investigations from which the author was able to identify four domestic areas on the landscape. The domestic areas are each examined for functional similarities and differences. The author describes the assemblage of each area and then compares the assemblages to explore similarities and differences in material culture, status, and community organization. The examination of domestic material at Arcadia Mill reveals that different segments of the population inhabited the uplands north and south of the industrial complex. This study provides a foundation for future investigations at Arcadia Mill and contributes to the larger framework of antebellum industrial research.

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 moreSmalltooth sawfish, Pristis pectinata, is the first elasmobranch listed as endangered under the US Endangered Species Act, yet basic life history data critical for its conservation and recovery are lacking. To address this lack of information, I examined aspects of smalltooth sawfish life history via analysis of vertebrae collected from deceased fish (n = 15). First, I estimated fish age by counting opaque bands in vertebrae sections. Age estimates ranged from 0.4 to 14.1 years for fish that ranged in size between 0.60 and 4.35 m total length. A von Bertalanffy growth function fit to size at age data resulted in parameter estimates of 4.65 m for L, and 0.206 for K, and - 0.80 y for t0. Rostral teeth were also examined for aging but no opaque zones were present. Analysis of vertebrae sections with laser ablation-inductively coupled plasma-mass spectrometry also was conducted to infer fish salinity history based on Sr:Ca and Ba:Ca ratios across vertebrae transects. The Ba:Ca ratios showed no patterns or peaks consistent with salinity. However, a consistent pattern existed within Sr:Ca among vertebra samples for the first two years of life, with peaks of high and low Sr:Ca either indicating migrations or seasonally variable estuarine salinity.

Asian swamp eel was initially discovered in Florida in 1997, yet little is known about its ability to disperse throughout the state or into neighboring states. Lack of cold tolerance is thought to limit swamp eel to south Florida similar to other sub-tropical non-native fishes.

Show moreAsian swamp eel was initially discovered in Florida in 1997, yet little is known about its ability to disperse throughout the state or into neighboring states. Lack of cold tolerance is thought to limit swamp eel to south Florida similar to other sub-tropical non-native fishes. Laboratory chronic and critical temperature experiments were used to assess cold tolerance and parameterize the cold stress accumulation model. In turn, this model was used to estimate swamp eel thermal tolerance during exposure to simulated winter temperature regimes. Critical thermal minima indicated swamp eel is remarkably tolerant to acute temperature changes; however, chronic exposure trials suggested only brief resistance to temperatures less than or equal to 11.3 C. Cold stress accumulation model simulations predicted swamp eel can tolerate some, but not all, fluctuating regimes consistent with mean winter temperatures in the southeastern USA. Thus, potential over-wintering range could extend as far north as Victoria in Texas, coastal wetlands in Louisiana, and Jacksonville in Florida. Current management efforts should focus on mitigating impacts in peninsular Florida where it may threaten sensitive habitats in the Everglades.

Show moreCurrently, no female-controlled method of sexual risk protection exists that provides a woman complete autonomy. For women engaging in sexual intercourse, barrier methods consist of both male and female condoms, neither of which are solely at the woman's discretion. Microbicides, chemical agents currently being developed to fill this void, would protect against human immunodeficiency virus (HIV) and other sexually transmitted diseases (STDs), potentially offering contraceptive properties. The current study assessed multiple variables potentially related to a woman's willingness to use microbicides, discovering that three variables accounted for 13% of the variance in a sample of 262 sexually-active, unmarried, college women aged 18 to 25. Casual relationship status, prior use of barrier methods for sexual protection, and the protective properties of microbicides were significant predictors of willingness to use microbicides. Other factors expected to contribute to a woman's willingness to use microbicides, such as age, race, and socioeconomic status, were not significant predictors in the model, possibly because of lack of variability on these dimensions in the sample. Future research needs to focus on interpersonal variables when considering a woman's willingness to use microbicides, as intrapersonal variables do not seem to represent the whole picture.

Show moreSince the 1950s, remote sensing has been a cornerstone of submerged archaeological site detection and study. Remote sensing technologies have advanced considerably in the past sixty years. It is critical for underwater archaeologists to keep abreast with these developments to ensure best practices are used for detecting, studying, monitoring, and developing policies for the protection and preservation of submerged cultural materials. In 2014, EdgeTech developed the EdgeTech 6205, a multi phase echo sounder capable of collecting interferometric bathymetric data and dual-frequency side scan sonar imagery. This system is unique in that its geometry specifically accommodates shallow water surveys; a capability most remote sensing equipment lacks. Its shallow water mapping capabilities have the potential to be particularly useful for underwater archaeologists as many submerged archaeological sites occur in shallower waters where the potential for ship groundings is especially high, and where the inundation of historic and prehistoric habitation sites is most likely. As a new technology, there is a dearth of information to assess the EdgeTech 6205's performance in underwater archaeological research. This thesis provides a comprehensive overview of the uses, challenges, and benefits in employing a shallow water-capable multiphase echo sounder to study submerged cultural materials. The project utilizes five different submerged archaeological sites, each with unique geographic parameters, as case studies to evaluate the EdgeTech 6205's performance as an archaeological tool. Further, this thesis includes an appendix which acts as a step-by-step guide for operating the EdgeTech 6205 in hopes that other researchers will be able to refine and build upon the techniques described throughout this paper.

Show morePrevious research has evaluated the cognitive effects of reproduction and motherhood, yet only a handful of studies have specifically evaluated maternal attention. Additionally, no study has been conducted to investigate the lasting effects of motherhood on attention. The Attention Network Test - Revised was selected to investigate mothers' lasting attentional network functioning during the years following childbirth. The current study used alerting, orienting, and executive control reaction times to compare mothers' and non-mothers' attentional performance. Potential protective factors were also investigated to determine what variables (e.g., age, sleep, stress, alertness) may predict attention scores. Results indicated that mothers and non-mothers have similar attentional capabilities; however, slower disengaging reaction times were related to motherhood and self-reported alertness. Questionnaire data suggest that together, age, sleep, stress, and alertness were not able to predict attention scores, but that several linear relationships do exist and demand further investigation. Additional research replicating this study's design with a larger sample size is recommended to explore the relationship between motherhood and attention in depth.

Show moreA previous study performed in the Northwest Florida Panhandle found the bank assessment of non-point source consequences of sediment (BANCS) model to be a relatively poor predictor of streambank erosion rates. Concern for whether these errors were related to how the project was constructed prompted the need for additional research. Some of the presumed errors were associated with the size of the study area and sites' exposure to extreme weather events during the study period. This study aims to utilize the BANCS model across a smaller study area than previously practiced with a focus on identifying specific flow events and drainage watersheds that are primarily undeveloped. Flow events were identified through the use of constructed gages and watersheds were verified with aerial imagery. Erosion incurred at the 18 study sites selected was measured over a given year following identified flood and bankfull events. These practices resulted in an improvement of BANCS' ability to predict streambank erosion rates. In particular, the bank erosion hazard index (BEHI) demonstrates strong relationships with erosion rates when plotted independently. The findings of the study indicate that a better understanding of return intervals of specific flow events, such as bankfull and floods, would enhance the capability to predict streambank erosion.

In the United States alone, approximately 150 individuals drown as a result of being caught in a rip current each year. A particular hotspot is the Florida Panhandle, where the landward migration of the nearshore bars over the summer season leads to quasi-permanent rip channels (Barrett and Houser, 2012).

Show moreIn the United States alone, approximately 150 individuals drown as a result of being caught in a rip current each year. A particular hotspot is the Florida Panhandle, where the landward migration of the nearshore bars over the summer season leads to quasi-permanent rip channels (Barrett and Houser, 2012). Since 2004, the number of lifeguards has increased, and the number of drownings on Pensacola Beach has decreased. However, the number of contacts made by lifeguards with swimmers is still over 30,000 a year. To assess beachgoers' perceptions of rip currents, 97 surveys were conducted on Pensacola Beach from June through September of 2010. Participants were asked questions to test their knowledge of rip currents. While a majority of participants suggested they could identify a rip current if present, less than 20% of the rip currents within the survey were correctly identified. This suggests that most beachgoers are overconfident in their ability to identify and poorly educated in ways to avoid beach hazards. Although signs about the hazards of rip currents are posted at every public access point, more is needed to properly educate the public on how to correctly identify and avoid dangerous rip currents.

Show moreAt-risk adolescents are a population that is intriguing and challenging to research. Particularly, the topic of at-risk adolescents and their everyday lives is difficult to understand and study. This study aimed for understanding at-risk adolescents' everyday problems. The researcher wanted to create a categorization of at-risk adolescents' everyday problems and how they perceive those problems. This study utilized qualitative measures, open-ended questionnaires, individual interviews, and focus groups, to uncover these everyday problems. In addition, the researchers used Corbin and Strauss's (2008) coding scheme to analyze and structure the results. It was found that at-risk adolescents experience problems on a multi-dimensional plane. Adolescents' problems were classified based on the theme, attribution, and context. It was found that adolescents' problems proved to be diverse and complex. This study has implications for at-risk adolescents' intervention techniques and program development. In addition, it supports previous research on multi-systemic therapy and cognitive behavioral therapy.

- Abstract/Description

Under normal conditions, individuals effortlessly allocate attention to detect changes in their surroundings due to the motion signals arising from those changes (Becker, Pashler, & Anstis, 2000). However, when visual changes coincide with natural (e.g., eye saccades) or induced visual disruptions (e.g., blank delays between stimuli called interstimulus intervals, or ISIs), these changes often go unnoticed due to a phenomenon called change blindness (Rensink, O'Regan, & Clark, 1997).

Show moreUnder normal conditions, individuals effortlessly allocate attention to detect changes in their surroundings due to the motion signals arising from those changes (Becker, Pashler, & Anstis, 2000). However, when visual changes coincide with natural (e.g., eye saccades) or induced visual disruptions (e.g., blank delays between stimuli called interstimulus intervals, or ISIs), these changes often go unnoticed due to a phenomenon called change blindness (Rensink, O'Regan, & Clark, 1997). Outside of the laboratory, existing driving literature has revealed that drivers feel safe glancing away from the road for 0.8 seconds (s) provided they have 3.0 s to view the road between wayward glances (Green, 1999). This experiment examined the role of individual differences in change detection performance across a range of ISIs (i.e., 0 s to 2.0 s) and across possible (e.g., pedestrian changes orientation) and impossible changes (e.g., green stop sign). Change detection accuracy and the mean iterations participants required to detect possible changes declined as the ISI increased, regardless of their working memory capacity or visual short-term memory capacity. The results show glances away from the road should be very brief because all individuals, regardless of working memory capacity, are susceptible to overlooking changes in their surroundings.

Show moreThis thesis proposes an automated technique for the initialization stages of the snakes active contour algorithm. Recent research has been conducted for automated snakes techniques due to current limitations of the algorithm because of the requirement for manual initialization of the snake contour by a human user. The use of manual initialization in large data sets is time consuming and inefficient. Automated methods allow for faster analysis among large data sets and unbiased segmentation results on images. Testing of the automated method is performed on sets of 2D x-ray images of burrfish. An automated form of the snakes algorithm is used to detect swimbladder regions in each image and results are compared to human identified ground truth regions. Automation of the initialization stage of snakes is achieved by a combination of image thresholding, blob detection, and mathematical methods pertaining to the known anatomy of burrfish. Given an x-ray image, the algorithm is initialized by performing blob detection and only placing initial snake boundaries that correspond to accepted swimbladder shapes within desired regions of interest relative to other distinct features within the image. This method allows for the entirely automated detection and segmentation of swimbladder regions in burrfish x-ray images.
