Show moreThis research study utilizes a one group correlational research methodology based on a conceptual framework grounded in the Human Performance Model. The purpose of the study is to examine specific personality and demographic characteristics that may be potential predictors of diving performance within a military environment. The research question for the study is "To what degree are specific personality and demographic characteristics potential predictors of diving performance?" Identification of specific traits as a standard selection process for predicting the success of diver candidates is a potential Human Performance Model consideration for military policy. The instrument used in the study was the Millon Index of Personality Styles Revised assessment tool and was administered to Navy Explosive Ordnance Disposal and Marine Combat Divers. The data were analyzed using multiple regression and multivariate analysis within the quantitative research design. The researcher discovered that 10 Millon Index of Personality Styles Revised scales were statistically significant in relationship to performance. Findings of the study lend strong support for this type of assessment tool for candidate selection to support the military diver training.

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

Show moreDuring the fall of 2005, faculty from the University of West Florida (UWF) were notified of ship remains located in the Blackwater River where the Seminole Lumber Camp once operated in the late nineteenth and early twentieth centuries. After an initial visit by faculty and students, it was determined that the remains were that of an eastern coastal paddle-wheel steamboat. The hull was intact, and the vessel was equipped with a boiler and walking beam steam engine. By the late eighteenth century, steam power became prevalent in the maritime industry and helped bring about the development of the eastern coastal paddle-wheel steamboat with its distinctive walking beam engine. The information contained in this thesis is the result of several field schools conducted between 2006 and 2010 where students extensively recorded the hull and the machinery, including the walking beam engine which engineers built in New York City in 1870. The thesis is an all-embracing summary of the students' hard work and provides detailed information on the history of lumbering and steam navigation in the area and the development and construction of the eastern coastal paddle-wheel steamboat.

Show moreEllenfrith's Song vitalizes the wife of the Old English poem "The Wife's Lament" who relates the thoughts of a woman exiled by her husband to live alone in a cave under an oak tree, but the poem gives no details of the circumstances that sentenced her to exile. Chapter One, "Exile," explores the betrayal by the trusted friend who causes the wife to be exiled and looks at her feelings of loneliness and alienation upon realizing how alone she is in the cave. Chapter Two, "First Sighting," begins in the cave, but through a flashback, the wife remembers how she first met her husband and how she became engaged to the man who has doomed her to a life in exile. Chapter Three, "Preparations and Marriage," relates the activities that probably took place in preparation for an Anglo-Saxon marriage and finishes with the exchange of gifts and the wedding vows that might have been said at an actual Anglo-Saxon marriage. After the ceremony, the bride says goodbye to her family and leaves with her husband for her new home, her new family, and her new life with him.

- 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.

A reef fish tagging study was conducted at unpublished artificial reef sites (n = 9) located between 15 and 20 miles south of Pensacola, Florida. A total of 3,110 fish was tagged with internal anchor tags on quarterly tagging trips from March 2005 to December 2007 to determine species-specific site fidelity and movement. The most frequently tagged species were red snapper (n = 2,114), red porgy (n = 422), gray triggerfish (n = 267), and gag (n = 96). Eighty-six fish were recaptured at tagging...
Show moreA reef fish tagging study was conducted at unpublished artificial reef sites (n = 9) located between 15 and 20 miles south of Pensacola, Florida. A total of 3,110 fish was tagged with internal anchor tags on quarterly tagging trips from March 2005 to December 2007 to determine species-specific site fidelity and movement. The most frequently tagged species were red snapper (n = 2,114), red porgy (n = 422), gray triggerfish (n = 267), and gag (n = 96). Eighty-six fish were recaptured at tagging reefs on subsequent tagging trips and fishers reported a total of 225 fish caught away from tagging sites. Results from joint-recapture models indicate that red snapper displayed the lowest site fidelity (11 - 21% y-1), while higher site fidelity was observed but not quantified for groupers and gray triggerfish. Red snapper displayed the greatest magnitude of movement with a mean distance (SD) moved of 24.2 km (3.85). It appears higher movement observed in red snapper made that species vulnerable to high fishing mortality at artificial and natural reefs in the region. Therefore, unreported artificial reef sites may not serve as effective no-harvest refugia for species that display low site fidelity and move between fished and unfished areas.

The question for what orders does there exist a subsquare-free latin square, has not been completely solved to date. We wish to extend the problem of finding subsquare-free latin squares to generalized sudoku squares. We give an attempted solution by constructing a generalized sudoku square with no subsquares of order m, where m 62 f2; ng. Additionally, when n is not equal to 2 or 4, we give a construction for a generalized sudoku square of order n2 with no intercalates.

Show moreDue to the high metabolic and physical demands involved in soccer, an optimal strength and conditioning program for female high school soccer players is essential. The benefits of resistance training and high intensity interval training in young athletes has been well documented; however, the effect of a concurrent strength and metabolic conditioning program on female athletes in specific sports has yet to be investigated. The current study examined the effects of an 8-week concurrent strength and metabolic conditioning program on body composition, flexibility, speed, agility, anaerobic capacity, strength, and power in female soccer players. Body composition and performance testing measures were recorded in female soccer players (n = 14, age = 16 +- 1.0 yrs) before and after an 8-week sports performance camp that combined high intensity interval training methods and periodized resistance training. Performance testing included 3-site skinfolds, sit and reach, pro agility test, 40-yd sprint, 300-yd shuttle run, and vertical jump. Strength testing included a 5-repetition maximum back squat, shoulder press, and bench press, and a 3-repetition maximum power clean. Comparisons were made using a paired samples t-test, and Pearson's correlations between variables were calculated. Significant improvements were made in vertical jump (p <0.05), pro agility test (p < 0.05), 40yd sprint (p < 0.05), squat (p < 0.05), shoulder press (p < 0.05), bench press (p < 0.05), and power clean (p < 0.05). There were significant correlations between power, agility and speed performance, as well as correlations between power and strength. An 8-week concurrent strength and conditioning program was effective for improving measures of fitness and performance in female soccer players. Overall, power and strength increased, as well as a significant decrease in time to complete the agility and speed testing. Strength and conditioning coaches can implement a preseason concurrent strength and metabolic conditioning program to improve soccer players' explosive strength and performance. Training protocols that use low volume and high loads (3 sets of 5-RM) to improve neural adaptations and avoid muscular hypertrophy can minimize the interference effect.

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

Show moreFishes live within a thermal range, and the limits of their tolerance are defined by various factors, some of which have been well studied (salinity, oxygen, etc.). This study, for the first time examined the effects of two previously overlooked factors, pressure and the osmolyte, trimethylamine-oxide (TMAO) on thermal tolerance of fish. The specific objectives of my study were to quantify the effects and possible relationships of increasing ambient pressure (mechanical mediation) or elevated TMAO concentrations (chemical mediation) on upper and lower thermal tolerance of pinfish (Lagodon rhomboides). Critical thermal methodology (CTM) was used to quantify thermal tolerance for pinfish exposed to increasing pressure and TMAO levels. As pressure was raised from 101.0 (ambient) to 4137 kPa, pinfish heat tolerance increased from 36.9 °C to 38.0 °C, whereas cold tolerance fell from 10.8 °C to 12.7 °C. The upward shift of thermal tolerance indicated a pressure-temperature link in a higher organism and may have ecological implications for deep-sea and hydrothermal vent organisms. Trimethylamineoxide failed to elicit an effect on pinfish thermal tolerance; however, the role of TMAO on fish thermal tolerance cannot be discounted as the results may reflect other factors not controlled for in the experiment.

Show moreThe mode of transmission of Helicobacter pylori, the cause of gastric ulcers in humans and a Class I human carcinogen, remains inconclusive. However, its presence in domestic animals or environmental waters is a public health hazard. In order to elucidate potential modes of transmission and circumvent limitations associated with the viable but non-culturable state of H. pylori, I used non-invasive molecular methods. I analyzed 290 fecal samples from 178 human and animal hosts, from four geographical regions: Florida, Kansas, Texas, and Nigeria using polymerase chain reaction (PCR) targeting 16S rRNA genes of Domain Bacteria and the isocitrate dehydrogenase (ICD) genes of H. pylori. Cycle sequencing coupled with phylogenetic characterization of PCR amplicons representing Helicobacter spp. revealed both the identity and relatedness of the organisms. Of the sampled hosts, 27 humans and 71 pigs tested preliminarily positive for H. pylori based on the 16S rRNA gene. Six pigs were conclusively H. pylori positive based on the sequencing of the ICD gene whereas others showed a closer relationship to H. mastomyrinus and H. rappini. Mouse model experiments elucidated both kinetics and relative-infectivity of different strains of Helicobacter. Infectivity varied with mouse strain but was generally detected between 1- 15 days post-inoculation.

Show moreThe purpose of this study was to determine whether a difference existed in the perceptions and attitudes toward work satisfaction between special education paraprofessionals employed at exclusively special education centers and special education paraprofessionals employed in special education programs located in regular education facilities. Further, this study sought to determine whether a difference existed in the perceptions and attitudes of the two groups relative to age, gender, ethnicity, educational level, and years employed. The Index of Work Satisfaction (IWS) measure was utilized to collect the data in this mixed method study. The IWS focused on pay, organizational policies, task requirements, interaction, and professional status. A sample of 214 special education paraprofessionals employed by the Escambia County School District in Florida participated in the study. The data analysis included a one-way ANOVA, a MANOVA, and descriptive statistics. Results of the ANOVA showed that on the IWS subscales of pay and organization policies there were statistically significant differences between special education paraprofessionals employed in exclusively special education centers and special education paraprofessionals employed in special education programs located in regular education facilities. Results of the MANOVA revealed a significant difference on the subscales of years plus tasks requirements, ethnicity plus years with interaction, and education plus level and plus years with autonomy between the two groups. Results of the analyses of the personal interviews found that the participants loved working with special needs students, but felt paraprofessionals were underpaid for their responsibilities. Other significant findings pointed to concerns of paraprofessionals such as lack of inclusion in the affairs concerning students, being treated with little respect, level of knowledge and skills, and the lack of autonomy. The interconnectivity of the IWS subscales suggested that further research is warranted to ascertain which of the subscales has the greatest impact on work satisfaction.

Show moreThe facilitating and impeding factors that affect faculty decisions in Saudi Arabia either to participate or not participate in Web-based instruction (WBI) were investigated in this study. Information about the characteristics of faculty and the effect of those characteristics on participation in developing WBI were also examined. Incentives and barriers to WBI, faculty attitudes, and participants demographic information were explored. This study was an investigation of the current use of WBI in Saudi institutions and the facilitating and impeding factors affecting faculty decisions to participate or not to participate in WBI. Information gathered regarding the attitudes of faculty toward development and implementation of a distance-education program in Saudi Arabia provided insight into the key issues concerning adoption and sustainability of distance education in general and WBI in particular. A survey research design was used. The survey was distributed in 2 forms, hard copy and online. Descriptive and inferential statistics were used to answer research questions. In this study, factors related to WBI were explored from the perspective of faculty in Saudi universities. In general, faculty had positive attitudes towards WBI.

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.

Show moreThe citizens of the United States have been affected by numerous major events. Interaction between these acute national/international events and personal events elicits stress responses likely to impact one's coping strategy. Because of their age, older adults' life experiences have exposed them to more stressful events than younger adults today, yet they continue living healthily. Therefore, the aim of this research was to examine the extent to which experiencing major stressful events impacts the ways in which one copes. Participants were surveyed on their alcohol use, coping strategies, and the major events they have experienced and the perceived impact of those events on coping. It was found that though older and younger adults drink about the same total amount, older adults drink more frequently. In addition, it was found that though consuming alcohol as a coping strategy was typically frowned upon by both groups, a greater proportion of the younger adults attributed this form of coping as a means to forget about current stressors.

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.

Microphytobenthos inhabiting subtidal estuarine sediments are important contributors to marine food webs and biogeochemical transformations of nutrients. Production and respiration rates, biomass estimations, and nutrient flux rates in Butcherpen Cove, Pensacola Bay, Florida, were investigated from February through August 2005 for the benthos, phytoplankton, and biofilms grown on artificial substrates. Extracellular enzyme activity was assayed on slurries of biofilm material. Production and...
Show moreMicrophytobenthos inhabiting subtidal estuarine sediments are important contributors to marine food webs and biogeochemical transformations of nutrients. Production and respiration rates, biomass estimations, and nutrient flux rates in Butcherpen Cove, Pensacola Bay, Florida, were investigated from February through August 2005 for the benthos, phytoplankton, and biofilms grown on artificial substrates. Extracellular enzyme activity was assayed on slurries of biofilm material. Production and respiration were measured by oxygen changes in light and dark incubations in situ. Microphytobenthic production and biomass decreased following major storm events. Water column phytoplankton and periphyton did not respond to rainfall and appeared to be controlled by temperature. Phytoplankton production and respiration increased through the sampling season and variability was low. Periphyton grown on artificial substrates did not correlate with benthic processes, but appeared to be responding to water column conditions. Bioavailability of water column nutrients did not seem to be as important to benthic production as much as benthic fluxes. The data suggest nitrogen and phosphorous nutrient co-limitations existed for both phytoplankton and benthic microalgae in Butcherpen Cove. When dissolved PO4-3 increased in the water column alkaline phosphatase activity was suppressed. Esterase activity of biofilms on artificial substrates reflected biofilm community respiration. N-fixation and denitrification rates were low and mutually exclusive.

The prevalence of obesity in Escambia County students was studied using data provided by the Escambia County School District and the Escambia County Health Department for the period covering 2006 to 2011. Every year, the Escambia County Health Department collects Body Mass Index (BMI) information from students entering first, third, sixth, and ninth grade. The average percentage of students with above-normal weight (BMI . 85th percentile) for the period studied was 28% for first grade, 35%...
Show moreThe prevalence of obesity in Escambia County students was studied using data provided by the Escambia County School District and the Escambia County Health Department for the period covering 2006 to 2011. Every year, the Escambia County Health Department collects Body Mass Index (BMI) information from students entering first, third, sixth, and ninth grade. The average percentage of students with above-normal weight (BMI . 85th percentile) for the period studied was 28% for first grade, 35% for third grade, 43% for sixth grade, and 38% for ninth grade. Comparing these percentages with national statistics indicates that the prevalence of obesity in Escambia County is equal to or higher than national averages. In particular, the prevalence of obesity among local female students has exceeded national averages for the last 3 years. The data indicate a clear trend of rapidly increasing obesity in elementary school children. On the other hand, obesity decreased from sixth to ninth grade. Correlations between data for the first and third grades suggest that a major contributor to obesity comes from the community or school zone served by each school. Schools with low-obesity levels and schools with high-obesity levels both show about the same rate of increase in obesity from first to third grade. The levels of obesity in elementary schools appear to be related to the degree of obesity already present in students entering first grade. Finally, no relationship was found between obesity and ethnicity and only a weak relationship was found between obesity and socioeconomic status for all grades except first grade.

This study was conducted in three contrasting northeastern Gulf of Mexico estuaries. Bimonthly sampling from January 2011 to November 2011 along with historic data from the National Estuarine Research Reserve System Wide Monitoring Program were used to assess light versus nutrient limitation. The data were applied to the Cloern (1999) model to identify the relative importance of light and nutrients in limiting phytoplankton growth. Nutrient enrichment bioassay experiments were conducted for...
Show moreThis study was conducted in three contrasting northeastern Gulf of Mexico estuaries. Bimonthly sampling from January 2011 to November 2011 along with historic data from the National Estuarine Research Reserve System Wide Monitoring Program were used to assess light versus nutrient limitation. The data were applied to the Cloern (1999) model to identify the relative importance of light and nutrients in limiting phytoplankton growth. Nutrient enrichment bioassay experiments were conducted for each of the three systems 5 to 6 times to identify nitrogen and phosphorous limitation of algal growth. Despite different physico-chemical characteristics, the three systems were largely limited by nutrients rather than light with seasonal and episodic exceptions. Nutrient enrichment of coastal ecosystems is a trend of concern due to the detrimental effects associated with this phenomenon. Increased algal biomass, increased frequency of harmful algal blooms, fish and invertebrate mortalities, and quantitative and qualitative habitat loss have all been documented manifestations of this process. While most coastlines are receiving increased nutrient loads, the ecosystem level responses are variable. In order to regulate watershed land use and acceptable nutrient loads, resource managers must be able to predict a system's response to potential changes in input.
