Several alternate systems for use in implementing the 911 emergency system in Orange County, Florida were investigated. The proposed systems were compared with the already existing systems on the basis of reliability, response time, and cost. System reliability was the prime consideration of the study. Flow charts of each system were formulated in order to determine the functions required of equipment and humans. The reliability was then determined by examining the difficulty of the tasks that each was required to perform. Reliability models of the present and proposed systems were constructed. By examining these models and comparing the reliabilities, response times, and costs, the most advantageous system configurations were determined. Two systems, Emergency Operator Call Transfer and Emergency Operator Call Relay, were selected as the most desirable; there were no appreciable differences in their reliability, response time, and cost.

This project developed computer graphics to display spatial and statistical data in a functional, appropriate and articulate manner. The spatial data creates mapping of Orange County focusing on traffic zones. The graphs display statistical data projecting from spatial areas presented in a simple form. The graphs produced by the system are geared towards an audience involved with transportation and planning decisions for Orange County. The graphics employ population, income, number of dwelling units, trip generation and trip production data based upon the 1980 census. The population, income, and number of dwelling unites statistics include predictions for 1985 through 2005 in five-year increments. The trip generation and production data is divided into six categories. These groups of statistics were chosen owing to their effect on the transportation system and travel characteristics of Orange County. The two-dimensional graphs display only spatial data. The three-dimensional graphs permit examination of one data category projecting from a large spatial area or up to four data categories projecting from one small six mile square of Orange County. All graphs presented in a three-dimensional form can be rotated around two axes.

The State of Florida has mandated that a statewide 911 system be implemented, and the Department of General Services, Division of Communications, has performed a study of possible 911 system configurations for Orange County based on the findings of a study performed by the Stanford Research Institute for the whole of the State of Florida. The Orange County study determined operator manning levels of the primary law enforcement agencies involved in the system and response times to citizen calls for each of the configurations proposed. This research generated computer simulation models of the two most likely to be implemented configurations for handling citizen calls. The models were run sing the input parameters defined in the Orange County study, and the results compared favorably. Additional runs were made with varying resource assignments to evaluate call service with respect to the level of performance and response time. The models were designed in modular form, such that they can easily be structured to conform to other operational configurations. This will allow evaluation of prosed systems prior to actual start up and analysis of resource requirements based on population predictions.

This project examines the scientific developments, strategic considerations, and political circumstances that led to the rise and fall of herbicidal warfare in Vietnam. The historical narrative draws on a wide range of primary and secondary source literature on the Vietnam War and the Cold War, the history of science, and American and international history of the 1960s and 1970s. The author conducted archival research in the United States in a variety government and non-government research facilities and toured formerly sprayed areas in Vietnam. This project utilizes oral history interviews of American and Vietnamese scientists who were involved in some aspect of the Agent Orange controversy. The thesis explains why American scientists were able to force an end to the herbicide program in 1971 and ensure that the United States would not engage in herbicidal warfare in the future. This political success can be understood only in the context of two major political transformations in the Vietnam Era: the collapse of Cold War containment as a salient model of American foreign policy, and the development of globally-oriented environmental politics and security regimes. The movement to end herbicidal warfare helped shift the meaning of security away from the Cold War toward transnational efforts to combat environmental problems that threaten all of the world's people. / History

Following active growth, the aquatic gram-negative rod Prolinoborus fasciculus (Aquaspirillum fasciculus) exhibited a mass conversion from its culturable rod form to a nonculturable coccoid form. Chloramphenicol did not prevent the conversion. Attempts to obtain variants that would not convert to the coccoid form were unsuccessful. Although the coccoid form fluoresced with acridine orange, agarose gel electrophoresis revealed extensive ribosomal RNA degradation. Poly-Ã -hydroxybutyrate, abundant in the vegetative rods, was not detectable in the coccoid cells. The results suggest that the coccoid form of A. fasciculus is a degenerative form rather than part of a life cycle. / Master of Science

The sperm chromatin structure assay (SCSA), as developed by Evenson et al.(1980), utilizes flow cytometry to quantify the susceptibility of sperm chromatin to in situ acid denaturation via the metachromatic properties of acridine orange. SCSA is repeatable and has been used to distinguish between fertile and subfertile males in different species; however, it does not permit morphological evaluation of cells. In the present study, the SCSA was modified for the fluorescence/differential interference contrast (DIC) microscope to examine morphology and chromatin stability on the same cell. Semen from six Holstein bulls was collected twice weekly for six weeks. Semen was cryopreserved after collection. A 48-hr scrotal insulation was applied after the first three collections to exert a mild thermal insult to the testes; this induces specific spermatozoal morphological abnormalities to appear in a predictable chronological order, as determined by Vogler et al. (1993). Using DIC optics, sperm head morphology was classified as normal, slightly misshapen, pyriform, severely misshapen, or tailless. Vacuolization in the head region was scored separately as apical, diadem, or random. SCSA and modified-SCSA for fluorescence microscopy were used to assess chromatin instability in the samples. The SCSA parameter of 'cells outside the main population of alpha t' (%COMP alpha t) and the modified-SCSA parameter of '% cells shifted from green' were positively correlated (r=0.84; P<0.01). Both variables were positively correlated with the appearance of tailless, pyriform, severely misshapen, and randomly vacuolated cells (P< 0.01), but not with the appearance of diadems or apical vacuoles. Also, the fluorescence microscope detected a significant shift from green in normally shaped cells appearing in morphologically abnormal ejaculates (P<0.01). These results demonstrate that scrotal insulation-induced morphological abnormalities in spermatozoa signify a perturbation in chromatin structure, and that the chromatin perturbation extends into normally shaped cells in the same ejaculate. / Master of Science

Discussions of the Deep South often ignore Florida and neglect to note the complexities of race relations throughout the state's history. Central Florida particularly has been overlooked and historians have yet to establish firmly the history of mid-twentieth century race relations in the region. Since there are few existing written accounts of the civil rights movement in Central Florida, this study attempts to contribute to the scholarly discourse about race in the region by investigating the desegregation of Orange County public schools. The bulk of this study is devoted to the 1962 case Ellis v. Board of Public Instruction of Orange County, Florida and how the case eventually desegregated the county's schools. The desegregation process was a long and arduous effort, but progress continued steadily and ten years after the suit was initiated, the county's school system bore little resemblance to the rigidly operated dual system of just one decade prior. This thesis sheds light on a previously overlooked segment of Central Florida's history and demonstrates why the untold story of Orange County's school desegregation effort is an important part of America's nationwide civil rights movement.
