The purpose of this study was to examine the relationship between teacher retention and student achievement as measured by the Florida Comprehensive Achievement Test (FCAT) Math Developmental Scale Scores (DSS). This study examined the impact of teacher transience on high school student math scores over a three-year period and considered the effect of teacher years of experience in relation to transience and achievement. For the purposes of this study teachers were identified into the following four classifications: Stayers, Within District Movers, Cross District Movers, or Beginning teachers. The findings indicated that students of beginning teachers scored significantly lower on the ninth grade math test than students of teachers in the other three classifications. At the 10th grade level there was no significant difference among the teacher transience groups. Based upon the findings, the following conclusion resulted from the study. Since an analysis of the data indicated that teacher retention is likely to improve ninth grade student score gains on the FCAT Math assessment, it is recommended that High School administrators carefully review the teaching assignments of ninth grade math teachers, especially in this era of high stakes testing and accountability. / by Francisco J.

In southeastern Florida, the majority of drinking water comes from the Biscayne aquifer. This aquifer is comprised of heterogeneous limestones, sandstones, sand, shell and clayey sand with zones of very high permeability. Visualizing the spatial variations in lithology, porosity and permeability of heterogeneous aquifers, like the Biscayne, can be difficult using traditional methods of investigation. Using the Roxar IRAP RMS software multi-layered 3D conceptual geomodels of the lithology, cyclostratigraphy and porosity were created in a portion of the Biscayne aquifer. The models were built using published data from borehole geophysical measurements, core samples, and thin sections. Spatial relations between lithology, cyclostratigraphy, porosity, and preferential flow zones were compared and contrasted to better understand how these geologic features were inter-related. The models show local areas of differing porosity within and cross-cutting different cycles and lithologies. Porosity in the Biscayne aquifer study area follows a hierarchy attributed to lithofacies with a pattern of increasing porosity for the high frequency cycles. This modeling improves understanding of the distribution and interconnectedness of preferential flow zones, and is thus an invaluable tool for future studies of groundwater flow and groundwater contamination in the Biscayne aquifer. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection

In south Florida, the Greater Everglades ecosystem supports sixteen species of wading birds. Wading birds serve as important indicator species because they are highly mobile, demonstrate flexible habitat selection, and respond quickly to changes in habitat quality. Models that establish habitat relationships from distribution patterns of wading birds can be used to predict changes in habitat quality that may result from restoration and climate change. I developed spatio-temporal species distribution models for the Great Egret, White Ibis, and Wood Stork over a decadal gradient of environmental conditions to identify factors that link habitat availability to habitat use (i.e., habitat selection), habitat use to species abundance, and species abundance (over multiple scales) to nesting effort and success. Hydrological variables (depth, recession rate, days since drydown, reversal, and hydroperiod) over multiple temporal scales and with existing links to wading bird responses were used as proxies for landscape processes that influence prey availability (i.e., resources). In temporal foraging conditions (TFC) models, species demonstrated conditional preferences for resources based on resource levels at differing temporal scales. Wading bird abundance was highest when prey production from optimal periods of wetland inundation was concentrated in shallow depths. Similar responses were observed in spatial foraging conditions (SFC) models predicting spatial occurrence over time, accounting for spatial autocorrelation. The TFC index represents conditions within suitable depths that change daily and reflects patch quality, whereas the SFC index spatially represents suitability of all cells and reflects daily landscape patch abundance. I linked these indices to responses at the nest initiation and nest provisioning breeding phases from 1993-2013. The timing of increases and overall magnitude of resource pulses predicted by the TFC in March and April were strongly linked to breeding responses by all species. Great Egret nesting effort and success were higher with increases in conspecific attraction (i.e., clustering). Wood Stork nesting effort was closely related to timing of concurrently high levels of patch quality (regional scale) and abundance (400-m scale), indicating the importance of a multi-scaled approach. The models helped identify positive and negative changes to multi-annual resource pulses from hydrological restoration and climate change scenarios, respectively. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection

This investigation compared statistical parameters for the blood serum chemistries of free ranging Osprey nestlings from Florida Bay and an Osprey population from Lake Istokpoga, in Central Florida (Chapter 1). Florida Bay Ospreys showed higher mean rank values for alanine aminotransferase (H=6.79, P=.009), alkaline phosphatase (H=6.48, P=.011), and sodium (H=5.7, P=.017), and Central Florida had higher mean rank values potassium (H=13.19, P=.000) and carbon dioxide (H=6.23, P=.013). Serum chemistries values were also compared between free-ranging Bald Eagle and Osprey nestling in Florida Bay estuary in southern Florida (Chapter 2). There were significant differences between serum values of Bald Eagle and Osprey nestlings. Bald Eagle serum values were higher for total protein (H=17.833, P=.00002), Albumin (H=7.449, P=.006), Aspartate aminotransferase (H=113.153, P =.0001), and Calcium (H=7.148, P = 008). Osprey serum values were higher for alanine aminotransferase (H=11.824, P = 0.0005), alkaline phosphatase (H=105.5, P =.0001), creatine kinase (H=13.465, P = 0.0002), carbon dioxide (H=4.443, P = 0.035) and cholinesterase (H=99.3, P=.0001). Sixteen nestling Bald Eagles were fitted with satellite platform transmitter terminal (PTT) or VHF radio transmitter package for a duration of six years (Chapter 3)= to identify their movement and dispersal. One of the 15 eagles migrated to North Carolina, whereas the other 14 (93%) confined their movements to Florida. Tracking duration per individual ranged from 82 to 1,531 days. We estimated first-year survival as 52% and 67% for the period from 1.5 to 3 years. Diamondback Terrapins (Chapter 4) were evaluated by an integrated assessment of physical, chemical, and physiological parameters. Extreme site fidelity of the turtles to mangrove habitat was evident along with a strong female biased sex ratio. There was a significant difference in the total number of individuals collected at the two sites (P =. 01) despite the total size and shorelines of the two sites being very nearly the same. Total recapture rate was 70% for combined population (TLK = 80% and CKW = 48%). We provide blood serum values and microbial cultures as baselines from these turtles in the wild. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection

This study was designed to determine the relationship between Florida School Recognition Program (FSRP) participation and adequate yearly progress (AYP) criteria met during school years 2004-2008. It also intended to discover whether schools' socioeconomic status, minority rates, and levels moderated this relationship as well as a difference in average AYP criteria met for schools that maintained FSRP participation and those that do not. The study further sought to determine whether these school characteristics and schools' grades predicted maintenance of participation in the FSRP. A quantitative method, including three statistical analyses, was employed to respond to 6 research questions and test 14 corresponding null hypotheses. Three thousand and seventy-seven schools were identified for data collection and analysis. Six independent variables were defined as school level, average socioeconomic status, average minority rate, average percentage of AYP criteria, aggregate number of years 100% of AYP criteria was met, and average school grade. One dependent variable was defined as aggregate years of FSRP participation. The study found that there was a relationship between participation in the FSRP and AYP criteria met, and school level, socioeconomic status, and minority rate moderated this relationship. While school level and minority rate moderated a difference in average percentage of AYP criteria met in schools that maintained participation in the program and those that did not, socioeconomic status did not. Moreover, all independent variables served as predictors for maintenance of participation in the FSRP. The study found that schools' demographic characteristics influence student achievement and participation in incentive pay programs. / Six implications for future research were identified to further explore the FSRP and AYP relationship, the unintended consequences of the No Child Left Behind (NCLB) Act, the appropriateness of incentive pay education, the distribution of FSRP award dollars in schools, and student achievement by school level. Recommendations were to add an AYP criterion to the FSRP, assess the effectiveness of inducement policies in education, and add a provision for program evaluation to the FSRP statute. / by Valerie Smith Wanza. / Vita. / Thesis (Ph.D.)--Florida Atlantic University, 2009. / Includes bibliography. / Electronic reproduction.

Deep injection wells (DIW) in Florida are regulated by the U.S. Environmental Protection Agency (USEPA) and the state of Florida through the Underground Injection Control regulations contained within the Safe Drinking Water Act. Underground injection is defined as the injection of hazardous waste, nonhazardous waste, or municipal waste below the lowermost formation containing an underground source of drinking water within one-quarter mile of the wellbore. Municipalities in Florida have been using underground injection as an alternative to surface disposal of treated domestic wastewater for nearly 40 years. The research involved collecting data as of September, 2007 on all the Class I DIWs in the state of Florida and evaluating the differences between them. The analysis found regional differences in deep well practice and canonical correlation analyses concluded that depth below the USDW is the most significant factor to prevent upward migration of the injected fluid. / by Jie Gao. / Thesis (M.S.C.S.)--Florida Atlantic University, 2010. / Includes bibliography. / Electronic reproduction.

This study detected and explored the existence of two proposed school cultures, the use of leader actions by principals, and the relationships between them, of a sample of 42 public schools in Southeast Florida. A quantitative non-experimental design was used, guided by eight research questions. One instrument, the BSJQ, was created for the purposes of detecting school normative cultures and another, the SLQ, was refined and used to detect principal leader actions. The existence of Business and Social Justice cultures was confirmed, and three latent cultures of Standards Performance, Democratic Community and Equity Curriculum were discovered. Of the schools participating, 74% had at least one of these cultures. The use of four leader actions was measured and statistically associated with different detected cultures. Managing/Transforming and Bridging actions were associated with all, Bonding was associated with all except the Equity Curriculum culture, and Bartering was associated only with the Business/Standards Performance culture. The schools' context had limited impact on the relationship between actions and culture. / Only higher student poverty increased the principal's use of Managing/Transforming actions in schools with a Democratic Community culture. Four principal demographics - years as principal, years at the school, undergraduate major, and level of graduate study - had a actions and school culture. The study reinforces Pisapia's (2009) theory of strategic leadership, develops new instrumentation to measure cultures associated with social justice and accountability, and provides guidance to principals and those who educate them on leader actions associated with desired school cultures. / by Daniel Reyes-Guerra. / Thesis (Ph.D.)--Florida Atlantic University, 2009. / Includes bibliography. / Electronic reproduction.

The face of North America's public education system is changing. Across the United States, hundreds of thousands of students have migrated away from traditional public school into charter schools. While both are considered public schools, often that is where the similarity ends. Claims and counter claims have been made about the virtues and advantages of a charter school versus the traditional public school. This study, focused on the nation's sixth-largest school system in Broward County, Florida, compares comments from stakeholders involved in charter programs to feedback from those still involved in the traditional public system. Three hypotheses are evaluated including: whether traditional schools are not adequately serving the needs of students; whether charter schools are better at serving student needs; or people believe that charter schools are doing a better job at serving the needs of students. Evidence suggests that while each model of education has its advantages and disadvantages, neither clearly provides a ""better" opportunity for students. Conclusions are that consumer perceptions are driving the shift in enrollment. This is attributed to the narrative about "choice" created by charter school advocates that aligns with American ideologies of liberty, freedom and independence. Ultimately, it is argued that the deconstruction of the traditional public education system is part of a larger effort to shift selected rights and privileges out of the public sphere and back into private control. For traditional public schools to regain momentum, they must learn to control the narrative and ultimately public policy and public opinion about our nation's public schools. / by Merrie Elyn Meyers. / Thesis (Ph.D.)--Florida Atlantic University, 2013. / Includes bibliography. / Mode of access: World Wide Web. / System requirements: Adobe Reader.

The largemouth bass (Micropterus salmoides) fishery was at an all time low on Lake Okeechobee when experimental supplemental stockings were done to try and enhance local bass populations. Largemouth bass had never been stocked on a large lake like Lake Okeechobee. The objectives were to develop a methodology, study dispersal, and compare stocked versus wild bass habitat choices. The methodology underwent considerable changes between studies. Bass dispersed to the edges by the second sampling period, so a larger sampling area may be needed. Water depth and pH were found to be significantly different between wild and stocked bass. Hatchery bass are naèive about predators, which may have resulted in stocked bass not moving to shallower areas like wild bass. The pH was weakly correlated with depth, so differences may be partially due to the fact that as depth increases, pH may also increase. / by Alyssa Jordan. / Thesis (M.S.)--Florida Atlantic University, 2012. / Includes bibliography. / Electronic reproduction.

The purpose of this exploratory study was to identify common practices of school-of-the-arts administrators and to determine if these commonalities differ from the practices of effective school leaders in general. A sample of administrators (n=92) completed a 3-part Likert survey based on the 21 attributes identified in the balanced leadership model. Five research questions guided this study which looked for both common and unique leadership challenges facing principals in schools of the arts. Prinicpals ranked the practices in order of importance. Although the statistical analyses revealed no significant differences among the variables of instructional levels (elementary, middle, and secondary), gender, or school grade designations, descriptive statistics as well as qualitative data found a number of emergent themes including principal outreach, principal advocacy, focus, flexibility, curriculum, funding challenges, and the commitment to being there(i.e., at the school). Based on the findings, a plus one model was developed illustrating the tensions across organizational management, instructional leadership, and artistic leadership, all of which must function simultaneously in order to lead a successful school of the arts. While only one study, the findings suggest that regular school principals might want to consider incorporating successful school-of-the-arts practices in their own schools. / by Kevin Gardner Perry. / Vita. / Thesis (Ph.D.)--Florida Atlantic University, 2012. / Includes bibliography. / Electronic reproduction.
