This dissertation analyzes the current status of emergency management professionalization in the United States and Florida using a qualitative case study. I investigate the efforts of various organizations at the national and state levels in the private and public sectors to organize emergency management as a profession. I conceptualize emergency management professionalization as occurring in two phases: the indirect institutionalization of the occupation of emergency management and the formal advancement toward an emergency management profession. The legislative, organizational, and procedural developments that occurred between approximately 1900 and the late 1970s became the indirect institutionalization of the occupation of emergency management. Over time, as our society developed and became increasingly complex, more disasters affect the security of the population. In order to adapt to increasing risks and vulnerabilities the emergency management system emerged and with it the necessary elements upon which a future profession could be established providing the basis for the formal advancement toward an emergency management profession. ^ During approximately the last twenty years, the formal advancement toward an emergency management profession has encompassed two primary strategies—certification and accreditation—motivated by the objective to organize a profession. Certification applies to individual emergency managers and includes all training and education. Accreditation of state and local emergency management agencies is reached by complying to a minimum level of proficiency with established standards of performance. Certification and accreditation are the mechanisms used to create an emergency management profession and thus act as axes around which the field of emergency management is organizing. ^ The purpose of this research is to provide a frame of reference for whether or not the field of emergency management is a profession. Based on sociology of professions literature, emergency management can be considered to be professionalizing. The current emergency management professionalization efforts may or may not be sufficient to achieve the ultimate goal of becoming a legitimate profession based on legal and public support for the exclusive right to perform emergency management tasks (monopoly) as well as self-regulation of those tasks (autonomy). ^

The goal of this project was to explore activism, attitudes, and imagery connecting Black churchgoers in Miami, Florida and the natural environment. The research approach was qualitative, began as exploratory research, and used the techniques of snowball sampling, participant observation, and semi-structured interviews. Three case studies representing various socio-economic levels, denominations, participant education levels, and environmental facets were chosen for in-depth ethnographic research. There are three major findings in the research. First, there is a link between the preservation of Black history and the preservation of the environment among Black churchgoers, who feel strong connections to a sense of place, rural life, and the past. However their work is strongly directed to bring about benefits for people and the environment in the present and the future. Second, public access to public lands is a basic and important right espoused by these Black churchgoing activists. Third, the vocabulary used by Black churchgoing activists regarding the natural environment differs from today's “mainstream” environmentalists. The concept of “beauty” is pivotal to Black appreciation of and activism toward the environment and is reminiscent of the early environmental protection movement in the United States and conservationists such as John Muir. These findings concerning how Black spirituality relates to the environment adds to the sparse literature on the subject, and provides for potential linkages between Blacks and “mainstream” environmental groups to benefit both parties. An understanding of the connections between Black spirituality and perceptions of the environment should facilitate the development of better programs to improve and protect the environment. Environmental projects may also address the social and economic needs of Black communities, churches, and congregations, as well as the ecosystem. ^

In a cross-sectional study design, risk factors for coronary heart disease (CHD) were evaluated in three groups: 66 Afro Caribbeans (FBCA) living in the US for less than 10 years, 62 US-born Afro Caribbean (USBCA) and 61 African American (AA) adults (18–40 years), with equal numbers of males and females in each group. Socio-demographic, dietary, anthropometric and blood pressure data were collected. Fasting blood glucose, blood lipids and high-sensitivity C-reactive protein (hs-CRP) were determined. ^ The USBCA and AA participants compared to the FBCA participants consumed significantly (p < 0.05) more mean total fat (g) (66.3 ± 41.7 and 73.0 ± 47.8 vs. 52.8 ± 32.3), saturated fat (g) (23.1 ± 14.9 and 24.9 ± 15.8 vs. 18.6 ± 11.5), percent energy from fat (%) (33.1 ± 6.5 and 31.4 ± 6.4 vs. 29.3 ± 6.8), fat servings (1.8 ± 1.2 and 1.5 ± 1.0 vs. 1.2 ± 0.9), dietary cholesterol (mg) (220.4 ± 161.9 and 244.1 ± 155.0 vs. 168.8 ± 114.0) and sodium (mg) (2245.2 ± 1238.3 and 2402.6 ± 1359.3 vs. 1838.0 ± 983.4) and less than 2 servings of fruits per day (%) (86.9 and 94.9 vs. 78.5). These differences were more pronounced in males compared to females and remained after correcting for age. Also, the percentages of USBCA and AA participants who were obese (17.1% and 23.0%, respectively) were significantly (p < 0.05) higher compared to FBCA (7.6%) participants. More USBCA and AA than FBCA individuals smoked cigarettes (4.8% and 6.6% vs. 0.0%) and consumed alcoholic beverages (29.0% and 50.8% vs. 24.2%). The mean hs-CRP level of the AA participants (2.2 ± 2.7 mg/L) was significantly (p < 0.01) higher compared to the FBCA (1.1 ± 1.3 mg/L) and USBCA (1.3 ± 1.6 mg/L) participants. ^ The FBCA participants had a better CHD risk profile than the USBCA and AA participants. Focus should be placed on the ethnic and cultural differences in a population to better understand the variations in health indicators among different ethnic groups of the same race. This focus can provide healthcare professionals and policy planners with the opportunity to develop culturally sensitive programs and strategies for the improvement of health outcomes. ^

Paracalanus quasimodo and Temora turbinata are two calanoid copepods prominent in the planktonic communities of the southeastern United States. Despite their prominence, the species and population level structure of these copepods is yet unexplored. The phylogeographic, temporal and phylogenetic structure of P. quasimodo and T. turbinata are examined in my study. Samples were collected from ten sites along the Gulf of Mexico and Florida peninsular coasts. Three sites were sampled quarterly for two years. Individuals were screened for unique ITS-1 sequences with denaturing gradient gel electrophoresis. Unique variants were sequenced at the nuclear ITS-1 and mitochondrial COI loci. Sampling sites were analyzed for pairwise community differences and for variances between geographic and temporal groupings. Genetic variants were analyzed for phylogenetic and coalescent topology. Paracalanus quasimodo is highly structured geographically with populations divided between the Gulf of Mexico, temperate Atlantic and subtropical Atlantic, in addition to isolation by distance. No significant differences were detected between the T. turbinata samples. Both P. quasimodo and T. turbinata are stable within sites over time and between sites within a sampling period, with two exceptions. The first was a pilot sample from Miami taken two years prior to the general sampling whose community showed significant differences from most of the other Miami samples. Paracalanus quasimodo had a positive correlation of Fst with time. The second was high temporal variability detected in the samples from Fort Pierce. Phylogenetically, both P. quasimodo and T. turbinata were in well supported, congeneric clades. Paracalanus quasimodo was not monophyletic, divided into two well-supported clades. Temora turbinata variants were in one clade with insignificant support for topology within the clade and very little intraspecific variation. Paracalanus quasimodo and T. turbinata populations show opposite trends. Paracalanus quasimodo occurs near shore and shows population structure mediated by hydrological features and distance, both geographic and temporal. The phylogeny shows two deeply divergent clades suggestive of cryptic speciation. In contrast, T. turbinata populations range further offshore and show little geographic or temporal structure. However, the low genetic variation detected in this region suggests a recent bottleneck event.

Ozone readings which exceeded the National Ambient Air Quality Standard of 120 ppbv were recorded in Miami, Florida during 1978 and 1980. Similar elevated concentrations of ozone extended across upper Florida and into the Southeastern portion of the United States. It is concluded that tropospheric transport of ozone into the Miami area occurs. This conclusion is supported by lead analyses of atmospheric samples taken in Miami and by isentropic trajectories. Six case studies are presented. In all cases transport of ozone into Florida appears to occur. In only four of the cases does this result in elevated ozone levels in Miami. In one case lower Florida was experiencing an oceanic influx of air and low ozone concentrations. In the other case Miami was experiencing a stagnation and high ozone concentrations apparently generated locally. The long range transport of ozone across the Southeastern United States appears to result from circulation within a weather pattern characterized by a stagnant high pressure system over the Southeastern United States.
