Title: An analysis of Florida's school districts' attendance policies and their relationship to high school attendance rates.
Creator: Reardon, Ryan Turner., Florida Atlantic University, College of Education, Department of Educational Leadership and Research Methodology
Abstract/Description: The purpose of this non-experimental correlational study was to determine the relationship between the type of attendance policies in the high schools of the 67 Florida school districts, the size of the school district (number of high school students), the socioeconomic status (SES) of the school district, and the average daily attendance rate of the district.

Show moreThe purpose of this non-experimental correlational study was to determine the relationship between the type of attendance policies in the high schools of the 67 Florida school districts, the size of the school district (number of high school students), the socioeconomic status (SES) of the school district, and the average daily attendance rate of the district. Additionally, the study determined if the relationship between policy type and attendance rate was moderated by SES and size. To test the research questions, high school attendance polices were examined and coded into one of three pre-determined categories: punitive, reward, or affective. The SES level and district size were also examined. A percentage was calculated for each district with respect to the makeup of attendance policies (by type). Polices that were punitive in nature were found to be most commonly implemented (mean 81.14 percent)., No significant relationships existed among the independent variables policy type, SES level and district size when tested with the dependent variable average daily attendance rate. Furthermore, district size and SES showed no significant moderation effects on the relationship between policy type and average daily attendance rate. An additional analysis of a large urban school district showed that when examining school level average daily attendance rates, school size showed no significant relationship, while school SES level did. The conclusion of this study was that while a heavy emphasis was placed on the implementation of punitive policy, when measured at the district level, average daily attendance rates were not significantly related to the variables of policy type, SES level, or district size, nor was the relationship between policy type and average daily attendance rate moderated by SES or district size., Recommendations for future research, school leaders, and policymakers were to assess the effectiveness of using reward and affective policies in conjunction with punitive policies, to conduct an assessment of policy effectiveness using school level data as the unit of analysis, and while attendance policies are typically created at the district level, schools should be given the autonomy to create and implement attendance programs conducive to their individual needs.

Title: Analysis of Kissimmee River floodplain seed dispersal for vegetation community restoration.
Creator: Mezza, Garren., Charles E. Schmidt College of Science, Center for Environmental Studies
Abstract/Description: This research examined the influence of hydrochory (seed dispersal via water), anemochory (seed dispersal via wind), and zoochory (seed dispersal by animals) on the re-establishment of the important floodplain vegetation communities of the Kissimmee River floodplain. Fifty-eight seed species were identified from 19,849 and 43, 894 seeds trapped in hydrochory traps in sites north and south of Oak Creek, respectively.

Fifty-eight seed species were identified from 19,849 and 43, 894 seeds trapped in hydrochory traps in sites north and south of Oak Creek, respectively. Seeds trapped by anemochory were measurable but were found to be far less important than hydrochory, while results showed no evidence of zoochory .... A number of interafting factors, e.g. hydrology, lack of remnants, seed phenology, etc. are limiting the dispersal of broadleaf marsh species north of Oak Creek, delaying range, expansion, and further community restoration.

Show moreThe 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.

Title: Attitudes and perspectives about backyard food gardening: a case study in South Florida.
Creator: Zahina-Ramos, John G., Charles E. Schmidt College of Science, Department of Geosciences
Abstract/Description: As cities grew throughout the past century, the availability of locally grown food declined, mostly because urban expansion occurred at the expense of adjacent agricultural land. As a result, city dwellers turned to commercial food market systems that import food from distant production areas. Private greenspace, which is one of the largest land cover types in cities, offers the potential for substantial agricultural production.

Show moreAs cities grew throughout the past century, the availability of locally grown food declined, mostly because urban expansion occurred at the expense of adjacent agricultural land. As a result, city dwellers turned to commercial food market systems that import food from distant production areas. Private greenspace, which is one of the largest land cover types in cities, offers the potential for substantial agricultural production. Because urban food production on private land, such as backyards, requires the willing participation of landowners, resident's feelings about and experience with food growing are important to understand. The demographic groups that were most likely to food garden were those in long-term relationships, higher income brackets, those with college education and residents over 50 years old. Incentives and programs focused on producing more from existing gardens may be most appropriate for people in these demographic groups, while other groups will most require basic food growing information. Study participants highly valued intangible benefits of food gardening (e.g., relaxation, feelings of happiness and satisfaction), often more than the provision of food. Most barriers and problems with backyard food growing, such as a lack of space and the need for gardening information, were similar for those who food garden and those who do not. Results from this study indicate that traditional agricultural incentives and perspectives must be rethought if they are to be applied in urban settings. By creating incentives and initiatives that reflect the needs and challenges faced by urban growers, urban agriculture will become an integrated part of the community, improving food quantity and quality while enriching residents' lives.

Show moreThis study compared the avian communities of treatment wetlands in South Florida called Stormwater Treatment Wetlands (STAs) to those in natural marshes and crop lands, and examined factors that influenced the size and structure of the avian communities within the STAs. The STAs contained a more abundant, rich and distinct avian community compared to reference land types. The STAs were dominated by wintering waterfowl, and therefore community patterns fluctuated more seasonally other land types. Within the STAs, density and richness in the fall and winter were much greater in the submerged aquatic vegetation than in the mixed emergent vegetation when waterfowl were present. The STAs maintain two vegetation treatments which enhanced their biodiversity value by supporting distinct avian communities with different migratory strategies This suggests the increase in treatment wetlands could partially offset the loss of natural wetlands, but avian communities in treatment wetlands are not surrogates for natural wetlands.

Despite significant skeletal fragmentation observed, articular facets were remarkbly complete, allowing for analysis of joint degeneration. While there does not appear to be a correlation between characteristics, the high prevalence of activity induced articular facets and osteoarthritis is indicative of extreme hyperdorsiflexion. Habitual kneeling and squatting postures are characteristic of hunter-gatherer subsistence activities as suggested by researchers such as Ubelaker (1975), Molleson (1969), and Trinkaus (1975).

Show moreWestern Palm Beach County, FL is characterized by thick deposits organic soils at shallow depths. Because of their high void ratio and compressibility, these soils undergo large primary consolidation followed by extended periods of secondary compression causing excessive premature structural distress. Although soil stabilization has been largely used with remarkable results in soft, expansive and non-organic soils, limited research and practice exist in the implementation with highly organic soils. The main motivation of this research was to investigate the effects of cement stabilization on the compressibility behavior of organic rich soils, and develop mix design criteria for optimum cement contents necessary to induce the desired engineering behavior. This optimized mix design may provide guidelines for Deep Mixing Methods in organic soils.

Show moreThe complex problems of the twenty-first century cannot be effectively addressed with twentieth century top-down bureaucratic governance alone because of limited stakeholder participation in collective decision making and/or implementation. The somewhat limited stakeholder participation in the policy process, especially, that of target populations, can impact generating viable solutions to complex problems. Collaborative governance has emerged as a promising alternative to traditional management in addressing contemporary complex problems. Collaborative governance is thus a type of governance that promotes joint participation of state and non-state stakeholders in decision making and/or implementation by using agreed upon processes of engagement to collectively address problems. Such governance is especially beneficial for addressing the challenges posed by the human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS). This dissertation uses the collaborative governance concept to explicate the efforts of HIV Health Services Planning Councils in Broward County and Palm Beach County of South Florida with the purpose of accentuating how collaborative governance works in providing various categories of services to meet the needs of people with AIDS (PWAs), as part of the implementation of the Ryan White CARE Act. The study focuses on critical variables of collaborative governance such as facilitative leadership and institutional design, the collaborative process variables such as trust building, commitment to the process and shared understanding, and outputs such as allocation priorities of the Councils. This study employed mixed methods in collecting data from various relevant sources., The combined findings from surveys, interviews, observations and document reviews were essential to knowledge and understanding of collaborative governance of the respective Councils. The results revealed more similarities than differences between the Councils in their efforts towards addressing the HIV/AIDS problem. The Councils are similar in all variables of collaborative governance with few exceptions relative to facilitative leadership and institutional design. The differences were relative to membership, number of committees, amount allocated for various service categories and number of clients served. Furthermore, the Councils were slightly different in reaching consensus on subjects of deliberation. On the average, Palm Beach County's Council make decisions by consensus relatively easily when compared with the Broward County's Council. Nonetheless, both Councils are consensus-oriented and strive to make decision by consensus as evidenced by unanimous votes or simple majority votes on various subjects of deliberation. In addition, representation and participation of target populations in collaborative governance have contributed to the empowerment of those target populations. The study contributes to the literature by developing a conceptual model for HIV/AIDS collaborative governance for producing outputs to help meet needs of target populations. Also, the study contributes to collaborative governance theorizing by drawing a nexus between variables of collaborative governance and by complementing the existing non-linear perspective of collaborative process for collective problem solving. Collaborative governance involving state and non-state stakeholders thereby enhances efforts of public managers by harnessing resources to effectively manage and/or address complex problems for the benefit of society.

Show moreDeep 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.

This period spanned the entire history to date of the Florida CCB. The data analyzed included selected institutional, financial, and baccalaureate characteristics of the Florida CCBs and for comparison included corresponding institutional and financial characteristics for the non-CCB institutions in the FCS. The data analysis investigated the relationships between these characteristics and the baccalaureate capital costs reported by Florida's CCB colleges. From these relationships, the historic average of the baccalaureate start-up capital cost was derived. In addition, the total baccalaureate capital cost for the system and for each Florida CCB college was also determined. As part of the process of conducting this study, a number of additional relationships between CCB and non-CCB institutions were explored, reported, and described.

Little is known about nitrogen (N) and phosphorus (P) limitation or the importance of morphological/physiological characteristics of bloom-forming macroalgae (Ulva lactuca, Hypnea musciformis, and Gracilaria tikvahiae) in the IRL. We hypothesized: 1) all species would proliferate in nutrient-rich Titusville, 2) opportunistic U. lactuca would dominate, 3) Rapid Light Curves (RLCs) would assess nutrient status, and 4) nutrient concentrations would regulate growth more than N:P ratios. Field studies showed rapid biomass doubling times of 2 days (U. lactuca; November 2012) in urbanized Titusville. RLCs in a guano-enriched island off Big Pine Key (BPK) and Titusville (Ulva spp.) were similar due to P-saturation. Laboratory studies showed three-fold higher RLCs and two-fold faster growth at high nutrient concentrations of N and P. Reductions of both N and P will be required to moderate future blooms.

Field observations and Landsat 5 TM imagery from 2003-2006 were separated into wet and dry seasons and temporally matched. Interpolation models of Inverse Distance Weighting and Kriging were compared to empirical regression models (Ordinary Least Squares and Geographically Weighted Regression - GWR) via their Root Mean Square Error. The results showed that salinity analysis is more accurate in the dry season compared with the wet season. Univariate and multivariate analysis of the Landsat bands revealed the best band combination for salinity analysis in this local area. GWR is the most conducive model for estimating salinity because field observations are not required for future predictions once the local formula is established with available satellite imagery.

In order to provide a quantitative methodology with which to differentiate between populations, samples of Recent and fossil populations were collected and measured for a variety of parameters. The parameters measured included length, width, spire height, and several angles, and allowed for a discriminate analysis to be completed. The analysis supported the distinction of several of the populations as ecophenotypes. Paleoenvironments of the fossil populations were then recreated using analogues of Recent populations.

This study examined the ability of simultaneous linear equations (SLE), CHEMTAX, and the Bayesian Compositional Estimator (BCE) to determine algal class composition in Florida Everglades periphyton. The methods were applied to artificial datasets, mixed lab cultures of known composition, and Everglades periphyton samples for which microscopic biovolume data was available. All methods were able to return accurate sample compositions for artificial data and mixed lab cultures. Correlation between pigment methods and microscopic results for natural periphyton samples was poor. SLE and CHEMTAX returned similar results for all samples while BCE performed less well.

Show morePixel based and object based vegetation community classification methods were performed using 30 meter spatial resolution Landsat satellite imagery of the Arthur R. Marshall Loxahatchee National Wildlife Refuge (Refuge), a remnant of the northern Everglades. Supervised classification procedures using maximum likelihood and parallelepiped algorithms were used to produce thematic maps with the following vegetation communities : wet prairie, sawgrass, cattail, tree island, brush, aquatic/open water. Spectral data, as well as NDVI, texture and principal component data were used to produce vegetation community classification maps. The accuracy levels of the thematic maps produced were calculated and compared to one another. The pixel based approach using the parallelepiped classification algorithm on the spectral and NDVI dataset had the highest accuracy level. A generalized form of this classification using only three vegetation communities (all wet prairie, tree island/brush and aquatic/open water) was compared to a previously published classification which used 1987 SPOT imagery in order to extract information on possible vegetation community transitions that are occurring within the Refuge. Results of the study indicate that 30 meter spatial resolution may be useful for understanding broad vegetation community trends but not species level trends. Pixel based procedures provide a more accurate classification than object based procedures for this landscape when using 30 meter imagery. Lastly, since 1987 there may be a trend of tree island/brush communities replacing wet prairie communities in the northern part of the Refuge and a transition to wet prairie communities in place of tree island/brush communities in the southern portion of the Refuge.
