Show moreEnvironmental Education (EE) has an overall goal of fostering eco-literate citizens who are capable of building a more sustainable planet (North American Association for Environmental Education, 2019). While EE is associated with a plethora of benefits, it is still not widely implemented in the field of education due to the many types of barriers as well as the complexity of EE content knowledge and skills. Professional Development (PD) in EE may be a viable way to increase effective implementation of EE, yet PD in EE is not widely attended or offered. It is, therefore, imperative that PD programs are designed in a way that will maximize the benefits for participants. This mixed methods case study examined the experiences of K-5 educators who attended a one-day, Everglades Literacy Teacher Training Workshop in order to understand the effective components of the workshop, changes in teacher content knowledge and self-efficacy, and experiences of teachers after the implementation of the Everglades literacy curriculum in their classrooms.

Basic mechanical properties, fiber volume fraction, moisture absorption curves and transverse tensile properties after water absorption were determined. Transverse fracture surfaces of dry and wet composites were inspected in a scanning electron microscope (SEM). In addition, the edge replication technique was applied. Micromechanical stress analysis of a composite subjected to mechanical, thermal and moisture loading were performed using analytical methods and finite elements. Transverse stiffness and stress levels for interfacial debonding and matrix failure were calculated and correlated with transverse stiffness and strength obtained experimentally.

Title: Remote sensing systems for monitoring and quantifying tropical deforestation in the Huallaga River Valley of Peru.
Creator: Echavarria, Fernando R., Florida Atlantic University, Craig, Alan K., Charles E. Schmidt College of Science, Department of Geosciences
Abstract/Description: This thesis examines the quantification of tropical deforestation, the use of remote sensing techniques for its scientific measurement, and the many controversies surrounding the problem. Aerial photographs and Landsat-based planimetric maps were used to determine the conversion of montane rain forest in a 1,000 km$\sp2$ sector of Peru's Huallaga River Valley. Between 1963 and 1976, 244 km$\sp2$ of forest (approximately a quarter of the study area) were converted to agricultural and other...
Show moreThis thesis examines the quantification of tropical deforestation, the use of remote sensing techniques for its scientific measurement, and the many controversies surrounding the problem. Aerial photographs and Landsat-based planimetric maps were used to determine the conversion of montane rain forest in a 1,000 km$\sp2$ sector of Peru's Huallaga River Valley. Between 1963 and 1976, 244 km$\sp2$ of forest (approximately a quarter of the study area) were converted to agricultural and other land uses, an apparent deforestation rate of 19 km$\sp2$/yr or approximately 1,872 ha/yr. The method entailed the cutting and weighing of strips of Mylar overlays. Despite the photogrammetric limitations, the results demonstrate an economical and practical technique that is readily applicable to developing countries. The potential of other remote sensing systems and the application of change detection techniques such as digital image subtraction to monitor deforestation is detailed.

Show moreThis empirical study examines decision-making in project selection in the face of overwhelming flood infrastructure needs and inadequate resources, particularly in vulnerable communities. The motivation for this study is to explore the interconnectedness between socioeconomic dimensions and environmental risks in the decision-making process for selecting projects. The study evaluates the Palm Beach County project selection framework and the impact of multi-criteria decision-making on project selection by proposing a new framework. The new project selection framework emphasizes the integration of flood risk and social vulnerability index criteria to evaluate the relationship between the new criteria in the decision-making framework and project selection. The analysis is comprised of 24 models grouped into three distinct groups and compared using paired t-tests. The analysis reveals that of the three groups, the group which incorporates both flood risks and social vulnerability criteria consistently outperforms the others, demonstrating its effectiveness in providing a more equitable investment for vulnerable communities that are more susceptible to floods. The findings provide valuable insights and recommendations for practitioners and scholars, emphasizing the need for a theoretical framework with objectivity to guide optimal infrastructure investments for decision makers.

Show moreThe United States established the Environmental Protection Agency (EPA) to monitor and enforce compliance with environmental pollution standards through various programs and policies. One such policy, the Audit Policy, allows companies to voluntarily self-report violations to the Agency in exchange for elimination of certain penalties. Despite the policy, firms still incur large environmental penalties, thus indicating the need for better understanding of the policy. A necessary but not sufficient condition for penalty relief under the Audit Policy requires discovery of violations by an environmental audit or a compliance management system. This research explores the option of discovery by a compliance management system and examines the motivation of managers to invest in an environmental management system (EMS). The theory of reasoned action (TRA) argues that attitude and subjective norms precede intentions. I use this theory to investigate what factors cause a manager to invest in an environmental management system (EMS). Additionally, I examine whether environmental attitude, tolerance for ambiguity and willful blindness are antecedents to attitude towards an EMS. In this study, I develop and test a scale of the willful blindness construct and measure its impact on managerial decision-making. The willful blindness construct development produced a one-item measure. My results support all hypotheses except for the predicted link between tolerance for ambiguity and attitude.

Title: Biomonitoring of hypoxia and sulfide stress in three sub-tropical seagrasses.
Creator: Irwin, Connor., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: Hypoxia and sulfide exposure, increased using glucose, are considered major environmental stressors in seagrass communities. Quantum efficiency, total soluble protein and catalase activity were quantified to evaluate the applicability of each of these bioindicators to detect environmental stress in three tropical seagrass species, Thalassia testudinum (Banks ex Kèoenig), Halodule wrightii (Ascherson) and Syringodium filiforme (Kuetz).

Quantum efficiency, total soluble protein and catalase activity were quantified to evaluate the applicability of each of these bioindicators to detect environmental stress in three tropical seagrass species, Thalassia testudinum (Banks ex Kèoenig), Halodule wrightii (Ascherson) and Syringodium filiforme (Kuetz). Hypoxia + sulfide treatments significantly decreased the quantum efficiency of all three species, but showed no response in protein and catalase activity. Although no treatment effect was found, catalase activity was enhanced in T. testudinum leaves and H. wrightii roots relative to other tissues, while S. filiforme showed no location-specific catalase activity. These results indicate that quantum efficiency is a more sensitive indicator than protein and catalase activity to hypoxia and sulfide stress in seagrasses.

Show moreUrban green space plays a vital role in the stability of the environment. Green spaces are increasingly becoming an integral part of the efforts to promote sustainability because of the different areas of benefits they provide. Sustainable city ranking systems were used to identify the most sustainable urban extents within the US. Landsat TM 4-5 imagery and textural classification are used as techniques in identifying, classifying and analyzing urban green spaces within nineteen urban extents. Patch analyst was used to analyze the location, structure and fragmentation green spaces within each urban extent. The aim is to determine to what degree urban green spaces can be considered to be an integral part of the sustainability of sustainable urban extents across the US and ascertain whether or not more sustainable urban extents do have more urban green spaces. The results of the study have shown that urban extents that are ranked highly v on sustainable ranking systems do not necessarily have to have large proportion of green spaces. Results have also shown that urban extents that are ranked high on sustainable rankings will not necessarily be affected by increase in population or decrease in urban green space. Finally human modified green spaces have simple geometric shapes compared to natural unaltered green spaces that have more complex geometric shapes.

Show moreEvery year millions of construction workers are exposed to dust in levels that create a hazard to them (Fundukian, 2011). Their environment is contaminated by activities such as cutting, chipping, grinding and sanding building materials. The Occupational Safety and Health Administration (OSHA) refers to this general collection of building materials debris and fine particulates as nuisance dust. Some of the particles in nuisance dust possess properties that make them especially hazardous, such as their shape or specific gravity. It has been found by the Center for Disease Control (CDC) that inhalation of quantities of silica dust above the permissible exposure limit (15.0 mg/m3) causes a deterioration of the outside lining of the lung.This research seeks to limit this exposure by a pretreatment process using acid application and then absorbed moisture content that reduces airborne particulate during the removal of cement stucco surfacing materials. Successful pretreatment would allow removal of CSSM from substrates such that the release of airborne particulates does not exceed the permissible exposure limits (PEL) found in the 29 CFR-Table Z-3 for mining applications (15-mg/m3).

Fifteen adult iguanas from two locations in Palm Beach County were tagged and had blood drawn for blood chemistry and HPLC steroid hormone analysis. Individuals were tracked for home range/territory analysis and behavioral observations. Blood chemistry values of cold-stunned individuals showed abnormal values similar to those reported in cold-stunned sea turtles. Territoriality and breeding behaviors, including nesting and head-bob displays, decreased or ceased during the following months. Steroid hormone concentrations were detected by HPLC and were not consistent with results from RIA studies in the literature.

Research has mainly focused on HAB identification, percent cover and other effects on the benthos but the relationship of HABs with upper trophic levels has received less attention. To study this relationship, a two-year investigation on a 10-m deep reef off of Hallandale Beach, was conducted. Stationary fish census coupled with benthic transect videos were conducted quarterly between April 2005-July 2007. A significant correlation between Lyngbya sp. blooms and alterations in fish assemblages was observed. Lyngbya had a negative interaction with fish species and abundance; additionally, HAB sample periods were significantly different from low algal abundance periods. Blooms of Dictyota sp. had no measurable relationship with the fish assemblage indicating HABs may have variable impacts on fishes depending on family, species and chemistry of the algae.

Show moreThe world currently has more people living in cities than in rural areas. In the United States this is no exception, and as a result government policy is focusing on the supply of 'green' jobs that help repair and expand its infrastructure in an attempt to help curb non-renewable resource use. The expansion of public transportation throughout the country is one facet of the multi-pronged US government policy. In the tri-county area of South Florida (Palm Beach County, Broward County, and Miami-Dade County) a research study known as the South Florida East Coast Corridor Transit Analysis (SFECCTA) entered Phase 2 in January 2009. This study looks at incorporating the FEC freight corridor which transverses the downtown areas of 47 cities into a major North- South commuter system. This system would also supplement the existing commuter Tri- Rail corridor. The proposed methodology in this manuscript attempts to address the issue of providing an adaptable, efficient and convenient public transportation in a low to medium density environment where the automobile is the preferred mode of travel. Emphasis is placed on connecting existing origin and destination locations in and around the greater West Palm Beach metropolitan area in Palm Beach County, FL. The goal of the methodology is to establish potential routes that will connect high amounts of residence to places of social interaction, consumption, employment, and the proposed SFECCTA regional transportation system with Light Rail Transit as the end goal. As a result the proposed corridors focus on creating dedicated and shared right of ways that already exist via the road network. The discussion and conclusion provide methodology successes, improvements, and economic development recommendations.

The specimens were subjected to alternate wet and dry cycles in specially constructed durability testing tanks. The specific objective was to evaluate the durability of different types of concretes with varying water-cementitious material ratios (0.3, 0.4, and 0.6), cement types (Types I and II), mineral admixtures (blast furnace slag, fly ash, microsilica), and steel types (black, galvinized and epoxy-coated rebars). The unreinforced cylindrical specimens were tested for compressive and splitting tensile strengths and the reinforced prismatic specimens for corrosion. The test results after 300 cycles of accelerated exposure indicated the adverse effects of the marine environment on the durability of concretes, resulting in loss of strength and corrosion resistance. The specimens with lower w/c ratios (0.3 and 0.4) showed good performance, whether or not they were admixture modified. However, mineral admixture inclusions improved the properties of strength and corrosion resistance of the specimens even with high w/c ratios (0.6). The specimens with regular rebars indicated least resistance to corrosion induced from the accelerated marine exposure compared to the ones with galvanized and epoxy-coated rebars.

Show moreThe Problem. The purpose of this study was to determine whether or not an eye-pleasing, carpeted, well-lighted, thermally controlled physical environment would have a positive impact upon the productivity of kindergarten children at Fairlawn Elementary School during the 1978-79 academic year. Summary. As each kindergarten child entered school at Fairlawn Elementary the child was randomly assigned, while considering race and sex constraints, to one of the two following physical environments: Traditional environment--three classrooms constructed in 1949 in which the physical environment consists of asphalt tile floors, incandescent lighting, no means for control of the thermal environment other than heating, a color scheme consisting of brown and tan, and with an area of 739 square feet per classroom or 30 square feet per child. Non-traditional environment--four classrooms constructed in 1974 in which the physical environment consists of wall-to-wall carpeting, indirect fluorescent lighting, a system through which the thermal environment is controlled and maintained at 72(DEGREES)F (+ or - 2(DEGREES)F) and between 40 per cent and 60 percent relative humidity, a color scheme of blue, green, and yellow, and with an area of 1,225 square feet per classroom or 49 square feet per child. The productivity of the kindergarten students assigned to the two environments was determined by analyzing the pre-test and post test scores on the Clymer Barrett Pre-Reading Battery. The pre-test was administered in September of 1978 and the post test was administered in May of 1979. A review of the literature showed that many factors contributed to the productivity of students. Among the many factors was the physical environment of the classroom. Procedure. The null hypothesis that was tested was stated: H(DEGREES): There is no significant difference between the productivity of students in a traditional classroom environment and those in a non-traditional classroom environment. In testing the hypothesis dealing with productivity of students, an analysis of variance was utilized. An additional analysis was completed to determine if the difference was due to individual teacher difference or due to the physical environmental condition of the classroom. The design used for this experiment was a one-factor hierarchial design analysis of variance. Conclusions. (1) There was a significant difference at the .10 level of confidence between those students in the traditional environment and those students in the non-traditional environment. The obtained difference was not significant, however, at the .05 level of confidence. (2) There was no significant difference at the .10 level of confidence among the individual teachers within the two environments studied in terms of the mean gain per classroom.

Wear curves were obtained for both materials by measuring specimen weight loss as a function of the number of cycles of relative motion, and surface damage of the specimens was photographed. The results indicate that a sea water environment has a strong influence upon the wear characteristics of mild steel and 304 stainless steel. For the mild steel, the corrosive effects of the sea water contributed to severe pitting and cracking of the wear surface and resulted in a significant increase in wear; after approximately 2.5 million cycles the amount of wear in sea water was approximately three times that in air. For the stainless steel, the sea water acted primarily as a lubricant and coolant, and served to reduce the amount of wear after 2.5 million cycles to about one-tenth of that in air.

The findings indicate superior behavior of fibers in flexure (toughness) and impact. Fibers affect the compressive strength only marginally. Kevlar fibers are more stable in the marine environment compared to steel and glass. The addition of latex significantly improves the durability characteristics. Endochronic constitutive modeling enables realistic prediction of beam flexural behavior. The smallness of the size and number of specimens tested indicates the need for further experimentation with an increased number of members of larger dimensions.

Show moreTwo wells installed in an unconfined, sandy aquifer in southern Florida exhibited low specific capacities and well loss coefficients resulting from borehole damage from drilling. Hollow-stem augers used to install the wells smeared drill cuttings onto the borehole walls reducing the hydraulic connection between the wells and the aquifer. Pneumatic fracturing was used to improve the specific capacity of both wells by improving the hydraulic connection with the aquifer. The pneumatic fracturing involved injecting air under high pressure into the surrounding formation to create a network of fractures. The success of the pneumatic fracturing was evaluated by recalculating the specific capacity and well loss coefficient of each well after the event. The results showed that both wells operated at increased discharge rates with improved specific capacities and well loss coefficients. High head loss coefficients indicated that the borehole damage was not completely repaired.
