The North Comes South Northern Methodists In Florida During Reconstruction

Bollinger, Heather K 01 January 2011 (has links)
This thesis examines three groups of northern Methodists who made their way to north Florida during Reconstruction: northern white male Methodists, northern white female Methodists, and northern black male and female Methodists. It analyzes the ways in which these men and women confronted the differences they encountered in Florida‟s southern society as compared to their experiences living in a northern society. School catalogs, school reports, letters, and newspapers highlight the ways in which these northerners explained the culture and behaviors of southern freedmen and poor whites in Jacksonville, Gainesville, and Monticello. This study examines how these particular northern men and women present in Florida during Reconstruction applied elements of “the North” to their interactions with the freedmen and poor whites. Ultimately, it sheds light on northern Methodist middle class values in southern society

2008 Emissions Inventory Of Central Florida

Ross, Jessica Leigh 01 January 2011 (has links)
An emissions inventory of VOCs, NOx, and CO2 was conducted for three central Florida counties – Orange, Seminole, and Osceola (OSO) – for calendar year 2008. The inventory utilized three programs: MOBILE6, NONROAD2005, and EDMS (Emissions and Dispersion Modeling System) to model on‐road mobile, non‐road mobile, and airport emissions, respectively. Remaining point and area source data was estimated from the Florida Department of Environmental Protection (FDEP) and the U.S. Environmental Protection Agency’s (U.S. EPA) 2008 emissions inventory. The previous OSO emissions inventory was done in 2002 and in the six years between inventories, there have been changes in population, commerce, and pollution control technology in central Florida which have affected the region’s emissions. It is important to model VOC and NOx emissions to determine from where the largest proportions are coming. VOCs and NOx are ozone precursors, and in the presence of heat and sunlight, they react to form ozone (O3). Ozone is regulated by the U.S. Environmental Protection Agency through the FDEP. The current standard is 75 parts per billion (ppb) and Orange County’s average is 71 ppb. A new standard (which will likely be about 65 ppb) is being developed and is scheduled to be announced by July 2011. If OSO goes into non‐attainment, it will need to prepare a contingency plan for how to reduce emissions to submit to the FDEP for approval. The 2008 inventory determined that approximately 71,300 tons of VOCs and 59,000 tons of NOx were emitted that year. The majority of VOCs came from on‐road mobile sources (33%) and area sources (43%), while the majority of NOx came from on‐road mobile sources (64%) and non‐road mobile sources (17%). Other major sources of VOCs included gasoline powered non‐road mobile equipment (lawn and garden equipment), consumer solvents, cooking, and gasoline distribution. With the numbers iii that could be determined for CO2 emissions, on‐road mobile and point sources were responsible for 93%. Of the point source CO2 emissions, almost all of it (87%) came from one large coal‐fired power plant in Orange County.

Thirty patients referred to out-patient clinic and mental hygiene clinic upon discharge from the Neurophychiatric Ward of the Veterans Administration Hospital, Coral Gables, Florida, between April 1, 1958 and October 1, 1958

Unknown Date (has links)
Social agencies for several years have been aware of the problems created by the clients failure to follow through with referrals for special and continued services. More recently, psychiatrists, psychologists, and social workers have focused attention upon after care for the discharged hospitalized patient. This study concerns itself with the use of after care services by the Veterans Administration Hospital's patients. The focus is on the veterans referred for after care to the Hospital Outpatient Clinic and the Mental Hygiene Clinic upon discharge from the hospital. The purpose of this study was to determine similarities and differences of those veterans. / Typescript. / "June, 1959." / "Submitted to the Graduate School of Florida State University in partial fulfillment of the requirements for the degree of Master of Social Work." / Advisor: David L.

A generalized stochastic birth/death population model based on Indian RiverLagoon dolphins

Unknown Date (has links)
For over a decade, researchers at Harbor Branch Oceanographic Institute (HBOI) have conducted surveys of the bottlenose dolphin (Tursiops truncatus) population of Indian River Lagoon (IRL) in Florida. I have constructed a 4-stage population model using the statistical program R. The model is used to conduct a viability analysis by analyzing the relationship between birth, calf and adult survival rates. The power analysis compares survey frequency to expected confidence intervals in estimating abundance. The sensitivity analysis shows that the population is most sensitive to changes in adult survival, followed by birth rate and calf survival. The model shows a strong chance of viability over a 50 year time span. The population is vulnerable to long periods of decline if birth, calf or adult survival rates fall below certain thresholds. Overall, the model simulates the future impacts of demographic change, providing a tool for conservation efforts. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection

Salinity Assessment, Change, and Impact on Plant Stress / Canopy Water Content (CWC) in Florida Bay using Remote Sensing and GIS

Unknown Date (has links)
Human activities in the past century have caused a variety of environmental problems in South Florida. In 2000, Congress authorized the Comprehensive Everglades Restoration Plan (CERP), a $10.5-billion mission to restore the South Florida ecosystem. Environmental projects in CERP require salinity monitoring in Florida Bay to provide measures of the effects of restoration on the Everglades ecosystem. However current salinity monitoring cannot cover large areas and is costly, time-consuming, and laborintensive. The purpose of this dissertation is to model salinity, detect salinity changes, and evaluate the impact of salinity in Florida Bay using remote sensing and geospatial information sciences (GIS) techniques. The specific objectives are to: 1) examine the capability of Landsat multispectral imagery for salinity modeling and monitoring; 2) detect salinity changes by building a series of salinity maps using archived Landsat images; and 3) assess the capability of spectroscopy techniques in characterizing plant stress / canopy water content (CWC) with varying salinity, sea level rise (SLR), and nutrient levels. Geographic weighted regression (GWR) models created using the first three imagery components with atmospheric and sun glint corrections proved to be more correlated (R^2 = 0.458) to salinity data versus ordinary least squares (OLS) regression models (R^2 = 0.158) and therefore GWR was the ideal regression model for continued Florida Bay salinity assessment. J. roemerianus was also examined to assess the coastal Everglades where salinity modeling is important to the water-land interface. Multivariate greenhouse studies determined the impact of nutrients to be inconsequential but increases in salinity and sea level rise both negatively affected J. roemerianus. Field spectroscopic data was then used to ascertain correlations between CWC and reflectance spectra using spectral indices and derivative analysis. It was determined that established spectral indices (max R^2 = 0.195) and continuum removal (max R^2= 0.331) were not significantly correlated to CWC but derivative analysis showed a higher correlation (R^2 = 0.515 using the first derivative at 948.5 nm). These models can be input into future imagery to predict the salinity of the South Florida water ecosystem. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

Post-fire Succession and Carbon Storage in the Northern Everglades

Unknown Date (has links)
Fire plays a key role in the ecology of the Everglades and is a ubiquitous tool for managing the structure, function, and ecosystem services of the Greater Everglades watershed. Decades of hydrologic modifications have led to the alteration of plant community composition and fire regime in much of the Everglades. To create a better understanding of post-fire recovery in sawgrass (Cladium jamaicense) communities, sawgrass marshes in the northern Everglades were studied along a chronosequence of time since fire and along a nutrient gradient. Areas closer to a water nutrient source and with fewer mean days dry contained greater total and dead aboveground graminoid biomass whereas live graminoid biomass was greater in areas with less time since fire and with fewer days dry. Post-fire characteristics of sawgrass marshes can provide insight on the effectiveness of fire management practices in the maintenance and restoration of quality habitat in the northern Everglades. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

Generating space-time hypotheses in complex social-ecological systems

Unknown Date (has links)
As ecosystems degrade globally, ecosystem services that support life are increasingly threatened. Indications of degradation are occurring in the Northern Indian River Lagoon (IRL) estuary in east central Florida. Factors associated with ecosystem degradation are complex, including climate and land use change. Ecosystem research needs identified by the Millennium Ecosystem Assessment (MA) include the need to: consider the social with the physical; account for dynamism and change; account for complexity; address issues of scale; and focus on ecosystem structure and process. Ecosystems are complex, self-organizing, multi-equilibrial, non-linear, middle-number systems that exist in multiple stable states. Results found are relative to the observation and the frame of analysis, requiring multi-scaled analytical techniques. This study addresses the identified ecosystem research needs and the complexity of the associated factors given these additional constraints. Relativity is addressed through univariate analysis of dissolved oxygen as a measure of the general health of the Northern IRL. Multiple spatial levels are employed to associate social process scales with physical process scales as basin, sub-basins, and watersheds. Scan statistics return extreme value clusters in space-time. Wavelet transforms decompose time-scales of cyclical data using varying window sizes to locate change in process scales in space over time. Wavelet transform comparative methods cluster temporal process scales across space. Combined these methods describe the space-time structure of process scales in a complex ecosystem relative to the variable examined, where the highly localized results allow for connection to unexamined variables. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection

Seminoles and settlers on the Florida frontier: using glass bottle analysis to reconstruct daily life at Stranahan’s trading post, Fort Lauderdale

Unknown Date (has links)
The early economic and social development of Fort Lauderdale began in the late nineteenth century. Today’s well-known Stranahan House in downtown Fort Lauderdale was originally the Stranahan Trading Post and General Store, which was in operation from 1894 to 1906. Adjacent to this building was a campground, which was used by early Florida white settlers and Seminole Indians. This thesis presents a study of 204 whole glass bottles recovered from the Stranahan campground archaeological site (8BD259). The analysis confirms that a greater proportion of the bottles were used when the property was a campsite. Moreover, soda/mineral water, not alcohol, was the more common type of beverage consumed at the site during this time. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2015. / FAU Electronic Theses and Dissertations Collection

Archaeomalacological Data and Paleoenvironmental Reconstruction at the Jupiter Inlet I Site (8PB34a), Southeast Florida

Unknown Date (has links)
The Jupiter Inlet I site is situated between the Atlantic coast and the Loxahatchee River in southeast Florida. Although excavations were previously conducted, faunal remains were not systematically collected until recently. Molluscan remains recovered in 2010 are examined to reconstruct past ecological habitats, identify which water bodies were used for extracting resources, and document changes in molluscan species over time. Based upon identifications, only brackish and marine species are represented, indicating that the Loxahatchee River was brackish rather than freshwater during the time of occupation and that the site inhabitants were collecting mollusks from both the lagoon and coastal waters. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

Distribution and Diversity of Benthic Foraminifera Within the Nearshore Ridge Complex off Pompano Beach, Broward County, Florida.

Unknown Date (has links)
Benthic foraminifera are exceptional organisms with distinctive features that allow for interpretation of both past and present environmental conditions. Some benthic foraminifera are widely distributed while some are restricted to specific environments due to their way of life. Foraminiferal assemblages south of Biscayne Bay and north of Cape Canaveral have previously been investigated; however, a gap exists in data covering a transitional zone along the Florida coast between the tropical waters of the western Atlantic and the cooler coastal waters along the North American coast. The purpose of this study was to collect baseline data on the benthic foraminifera of the small marine environment off of Pompano Beach that falls within this zone. This environment has a very particular relict reef system that includes a near-shore ridge complex, the unique foraminiferal assemblage of which has not been documented. Thirteen rubble samples were collected from this near shore ridge complex between October 2013 and April 2015 from depths of 2.5m – 9m. Abundances and diversity indices were calculated, and multivariate analysis and SHEBI analysis carried out to summarize baseline data for the area. Substrate types and seasonal collections were compared with foraminiferal abundances to determine if benthic foraminifera diversity varied between the four substrate types found on the near-shore ridge and between wet and dry seasons in Florida. Results revealed a variation in abundances for both substrates and seasons with the dominant genera being Quinqueloculina, Laevipeneroplis, and Archaias. Multivariate analysis displayed dissimilarities between substrates colonized by corals and those that were uncolonized. Comparison of studies from surrounding areas revealed fewer, however similar, species and different dominant genera. Overall, this area has proven to be a different environment compared to surrounding coastal areas and merits further investigation. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection
