Can Florida become like the next Florida? When metaphoric comparisons fail.

Metaphors can be understood in either of two ways: via a comparison process or via a categorization process. What determines which process will be used? According to a recent variant of comparison theory, novel metaphors must be processed as comparisons; only conventional metaphors can be processed as categorizations. We argue that choice of process is determined not by conventionality, but instead by the semantic and referential properties of the metaphor itself. We identified a type of novel metaphor that is indeed understood more quickly as a comparison than as a categorization. We then generated variants of such metaphors to make comparison difficult and found that these new novel metaphors were understood more quickly as categorizations than as comparisons. We conclude that metaphors can be processed as categorizations from the start, depending on their semantic and referential properties.

AAPI youth tobacco use: a comparative analysis of current cigarette use data from the Florida, Texas, and National Youth Tobacco Surveys.

OBJECTIVES: The objectives of this study were to compile data on Asian American and Pacific Islander (AAPI) youth tobacco use in Florida and conduct comparisons with state and national data. This research will contribute to reducing the gap in information regarding current smoking prevalence among AAPI youth in Florida and provide direct comparisons with another state (Texas) and National Youth Tobacco Survey (NYTS) data on AAPI youth. METHODS: Current cigarette use data from the Florida Youth Tobacco Surveys conducted in 1998, 1999, and 2000 were examined for trends in AAPI and state prevalence rates. AAPI data from Florida's baseline 1998 youth tobacco survey were compared to Texas data after applying a common set of data preparation edits. AAPI data from the NYTS were also compared to Florida's AAPI youth population. FINDINGS: Current cigarette use for AAPI students in Florida was generally below the overall prevalence rates among Florida's public middle or high school students. In 1998, current smoking prevalence among Texas AAPI middle and high school students was 18.7% compared to 19.4% among Florida students. Among high school students, the NYTS found that 21.2% of AAPI students were current cigarette smokers nationally in comparison to 21.7% of AAPI high school youth in Florida. In middle school, the current smoking prevalence among AAPI students was 5.5% in the NYTS as compared to 9.4% in Florida. The NYTS data in particular highlight the magnitude of the increasing trend of cigarette smoking among AAPI youth as they progress through the high school grades. CONCLUSIONS: Of all the racial/ethnic groups in Florida, only AAPIs did not have a significant decline in current cigarette use. While the Florida Tobacco Pilot Program has implemented many worthwhile initiatives, the anti-tobacco interventions do not appear to have exerted a noticeable effect on AAPI youth.

Historical and other patterns of monomethyl and inorganic mercury in the Florida panther (Puma concolor coryi).

Since the late 1980s, elevated levels of mercury have been reported in the tissues of the Florida panther (Puma concolor coryi) from the Florida Everglades. The extent, degree, and length of time of mercury contamination in the Florida panther are unknown. The objective of this study was to determine the historical and other patterns of monomethyl and inorganic mercury in the Florida panther by analysis of mercury in panther hair from museum collections. In addition, this study evaluated the effects of preservation of skins on mercury concentrations in hair and the representativeness of museum collections for evaluating historical trends of contamination in the Florida panther. Hair from 42 Florida panther specimens collected from 1896 to 1995 was analyzed for both monomethyl and inorganic mercury. Monomethyl mercury (MMHg) and inorganic mercury (IHg) were found in all specimens. Monomethyl mercury in hair from untanned skins was significantly higher than MMHg in hair from tanned skins. For untanned specimens, the mean MMHg concentration in hair was 1.62 +/- 1.87 mug/g (range 0.11 to 6.68 mug/g, n = 16). Monomethyl mercury accounted for 88% of the total mercury in untanned Florida panther hair. No sexual or geographical differences were found. Although MMHg is generally stable in hair, the tanning process appears to reduce the amount of MMHg in hair. In addition, exogenous IHg contamination of the panther hair was found in museum specimens, especially in older specimens. The implication of these and other factors in interpreting results of museum studies is discussed. The presence of MMHg in panther hair since the 1890s indicates long-term and widespread exposure of the Florida panther to mercury. Levels of MMHg are significantly greater in the 1990s than the 1890s. When combined with field studies of mercury in the Florida panther, considerable individual variability is observed, reflecting short-term changes in exposure of individual panthers to mercury. Although museum specimens showed a significant increase in MMHg over the last 100 years, they did not show the magnitude of increase that field populations of Florida panthers did. A number of Florida panthers appeared to be at risk from mercury over their lifetimes, especially individuals from the early 1990s.

Vitamin A concentrations in serum and liver from Florida panthers.

Many of the anomalies and clinical signs afflicting the Florida panther (Felis concolor coryi) are suggestive of vitamin A deficiency. Our objectives in this study were to determine if a vitamin A deficiency exists in the free-ranging panther population and to determine if there are differences in vitamin A levels among various subgroups of free-ranging panthers. Retinol concentrations were used as an index to Vitamin A concentrations and were determined in serum and liver from free-ranging (serum, n = 45; liver, n = 22) and captive (serum, n = 9; liver, n = 2) juvenile and adult Florida panthers from southern peninsular Florida (USA), and in liver from free-ranging cougars (F. concolor subspp.) from Washington (USA) and Texas (USA) between November 1984 and March 1994. Combined juvenile (6- to 24-mo-old) and adult (> 24-mo-old) free-ranging Florida panthers had mean +/- SD serum retinol concentrations of 772.5 +/- 229 pmol/ml. Adult free-ranging Florida panthers had mean liver retinol concentrations of 4794.5 +/- 3747 nmol/g. Free-ranging nursing Florida panther kittens (age < 1 mo) had mean serum retinol concentrations of 397.9 +/- 69 pmol/ml. Among subgroups of free-ranging Florida panthers, females had higher corrected mean serum retinol concentrations than males and adult free-ranging Florida panthers had higher mean liver retinol concentrations than juveniles. Retinol concentrations in free-ranging Florida panthers did not differ significantly from those in captive panthers (liver and serum) or other free-ranging cougars (liver). Based on limited published values and our controls, a vitamin A deficiency could not be demonstrated in the Florida panther population nor were any subgroups or individuals considered deficient.

Mercury concentrations in red drum, Sciaenops ocellatus, from estuarine and offshore waters of Florida.

Dorsal muscle tissue from 712 red drum, Sciaenops ocellatus, from Florida waters were analyzed for total mercury content. Mercury levels detected in these red drum varied but in most study areas were usually lower than regulatory threshold guidelines. Total mercury levels in individual fish from all study areas ranged from 0.020 to 3.6 ppm (wet weight). Total mercury levels detected in red drum from the Florida Keys-Florida Bay area were often higher than those in fish from all other estuarine study areas. Positive relationships between total mercury levels and fish size (length and weight) and fish age were observed in most Florida study areas, indicating that mercury levels tend to increase over time as red drum grow. The majority of large, mature red drum examined contained mercury levels greater than the 0.5-ppm threshold level set by the Florida Department of Health (DOH). Approximately 94% of all adult red drum from offshore waters adjacent to Tampa Bay contained mercury levels greater than or equal to the 0.5-ppm threshold level, and 64% contained levels greater than or equal to the DOH 1.5-ppm "no consumption" level. All fish from this area with mercury levels greater than 1.5 ppm were large individuals (670 mm SL). Eight percent of legal-size red drum from Florida waters contained total mercury levels greater than or equal to the 0.5-ppm threshold level. The majority (52%) of these legal-size fish greater than or equal to 0.5 ppm were from the Florida Keys-Florida Bay area. In the Florida recreational fishery, the current maximum size limit for this species is an effective filter that prevents humans from consuming those red drum with the greatest likelihood of containing high mercury levels.

Citrus leprosis and its status in Florida and Texas: past and present.

According to published reports from 1906 to 1968, leprosis nearly destroyed the Florida citrus industry prior to 1925. This was supported with photographs showing typical leprosis symptoms on citrus leaves, fruit, and twigs. Support for the past occurrence of citrus leprosis in Florida includes: (1) presence of twig lesions in affected orange blocks in addition to lesions on fruits and leaves and corresponding absence of similar lesions on grapefruit; (2) yield reduction and die-back on infected trees; and (3) spread of the disease between 1906 and 1925. Transmission electron microscopy (TEM) examination of tissue samples from leprosis-like injuries to orange and grapefruit leaves from Florida in 1997, and fruits from grapefruit and sweet orange varieties from Texas in 1999 and 2000 did not contain leprosis-like viral particles or viroplasm inclusions. In contrast, leprosis viroplasm inclusions were readily identified by TEM within green non-senescent tissues surrounding leprosis lesions in two of every three orange leaf samples and half of the fruit samples obtained from Piracicaba, Brazil. Symptoms of leprosis were not seen in any of the 24,555 orange trees examined across Florida during 2001 and 2002. The authors conclude that citrus leprosis no longer exists in Florida nor occurs in Texas citrus based on: (1) lack of leprosis symptoms on leaves, fruit, and twigs of sweet orange citrus varieties surveyed in Florida: (2) failure to find virus particles or viroplasm inclusion bodies in suspect samples from both Florida and Texas examined by TEM; (3) absence of documented reports by others on the presence of characteristic leprosis symptoms in Florida; (4) lack of its documented occurrence in dooryard trees or abandoned or minimal pesticide citrus orchard sites in Florida. In view of the serious threat to citrus in the U.S., every effort must be taken to quarantine the importation of both citrus and woody ornamental plants that serve as hosts for Brevipalpus phoenicis (Geijskes), B. californicus (Banks), and B. obovatus Donnadieu (Acari: Tenuipalpidae) from countries where citrus leprosis occurs.

Genetic connectivity in the Florida reef system: comparative phylogeography of commensal invertebrates with contrasting reproductive strategies.

Effective spatial management of coral reefs including design of marine protected areas requires an understanding of interpopulation genetic connectivity. We assessed gene flow along 355 km of the Florida reef system and between Florida and Belize in three commensal invertebrates occupying the same host sponge (Callyspongia vaginalis) but displaying contrasting reproductive dispersal strategies: the broadcast-spawning brittle star Ophiothrix lineata and two brooding amphipods Leucothoe kensleyi and Leucothoe ashleyae. Multiple analytical approaches to sequence variation in the mitochondrial COI gene demonstrated a high degree of overall connectivity for all three species along the Florida reef system. Ophiothrix lineata showed significant genetic structuring between Florida and Belize, and a pattern of isolation by distance but no significant genetic structuring along the Florida coastline. Bayesian estimates of migration detected a strong southerly dispersal bias for O. lineata along the Florida reef system, contrary to the general assumption of northerly gene flow in this region based on the direction of the Florida Current. Both amphipods, despite direct development, also showed high gene flow along the Florida reef system. Multiple inferences of long-distance dispersal from a nested clade analysis support the hypothesis that amphipod transport, possibly in detached sponge fragments, could generate the high levels of overall gene flow observed. However, this transport mechanism appears much less effective across deep water as connectivity between Florida and Belize (1072 km) is highly restricted.

Hepatocellular carcinoma incidence in Florida. Ethnic and racial distribution.

BACKGROUND: Hepatocellular carcinoma (HCC), the primary form of liver carcinoma, is increasing in incidence worldwide. The increasing numbers of Hispanic immigrants in Florida suggest that the rate of HCC in the Hispanic population should be of special concern. This study describes racial and ethnic distribution and trends of incident HCC in Florida from 1985 to 1995. METHODS: A total of 2837 cases of incident HCC from 1985 to 1995 were examined from Florida's incident cancer registry, the Florida Cancer Data System. Age standardized and age specific average annual incidence rates were calculated for the state of Florida by gender and by racial and ethnic group. RESULTS: Over the study period, the average annual incidence HCC rates in Florida among male and female Hispanics and blacks were consistently and significantly twice the rate of white males and females as standardized rate ratios. Males were at least twice as likely to have HCC compared with females in all three racial and ethnic subpopulations. CONCLUSIONS: The incidence of HCC in Florida was comparable to the overall U.S. incidence with respect to average annual incidence and gender distribution. Florida blacks and Hispanics are at significantly increased risk for HCC incidence compared with Florida whites. These results have implications for preventive HCC recommendations in growing racial and ethnic subpopulations in the United States.

Population affinities of 19th Century Cuban crania: implications for identification criteria in South Florida Cuban Americans.

Identification criteria, specifically discriminant function formulae derived from traditional craniometrics, currently used in South Florida for Cuban Americans and other "Hispanic" groups, are unsuitable to provide adequate biological profiles due to complex biological histories as well as widely diverse geographic origins. Florida's total population is approximately 16 million (15,982,378) individuals. Of the total population 2.682,715, or 16.8%, are self-identified as "Hispanic". South Florida (herein defined as Miami-Dade, Broward and Collier Counties) is home to 60% of the total Hispanic population of Florida with 1,291,737 (48.15%) residing in Miami-Dade County. The Hispanic population of Miami-Dade County makes up 57.0% of the total population of 2,253,362. Each recognized sub-group of Hispanics (Mexican, Puerto Rican, and Cuban) includes its own geographic point-of-origin and population history. Cuban-Americans (arriving in the late 1950's and early 1960's) make up the largest sub-population of Florida's Hispanics in any county and in Miami-Dade number 650,601 or 51% of the total Latin population. Additionally, as in other agricultural states, Florida has a very large population of undocumented workers who primarily arrive from Texas and points south of the Straits of Florida. Thus the application of the available traditional craniometric and non-metric methods are not appropriate for South Florida's Latin population. To begin to address this issue in relation to South Florida's Cuban population, we present an analysis of cranio-facial shape variation in a 19th Century Cuban sample, 17th Century Spanish sample, a Precontact Cuban sample, and Terry Blacks using geometric morphometric methods. Significant biological shape differences and patterns of variation are observed among the groups. These results provide us with a context in which to begin to understand the biological variation of Cuban Americans, which will enable the development of identification criteria specific for this U.S. hybrid Hispanic community.

Comparison of naturally acquired parasite burdens among Florida native, Rambouillet and crossbreed ewes.

The response to natural infection by gastrointestinal nematodes was evaluated in three groups of lambing mature ewes: 16 Florida Native; 21 Rambouillet; and 18 1/2 Florida Native x1/2 Rambouillet (F1 generation). Fecal egg counts (FEC), packed cell volume (PCV) and plasma protein levels were determined periodically through a one-year period. The highest FEC was recorded in Rambouillet ewes, with most of the means higher than 1000 eggs per gram (EPG). Florida Native and F1 ewes showed similar trends in FEC, with most of the means below 500 EPG. The highest mean PCV values were recorded in Florida Native ewes, followed in decreasing order by F1 and Rambouillet ewes. F1 ewes showed the lowest plasma protein levels and Florida Natives the highest. Fecal cultures revealed the highest percentages of Haemonchus larvae in Rambouillet ewes (>64%) and the lowest percentages in Florida Native ewes. Florida Native and F1 ewes were more resistant to gastrointestinal nematode infections than were Rambouillet ewes. High negative correlation coefficients between FEC x PCV and FEC x plasma protein levels coincided with peaks in mean FEC of Rambouillet (May and July), Florida Native and F1 ewes (October). This study showed that crossbreeding Rambouillet and Florida Native sheep resulted in the production of F1 ewes resistant against gastrointestinal nematode infections.

Processes influencing rainfall deposition of mercury in Florida.

The primary goal of the Florida Atmospheric Mercury Study (FAMS) was to quantify the atmospheric deposition of Hg throughout Florida. Monthly integrated precipitation and weekly integrated particulate samples were collected at 10 sites in Florida for periods ranging from 2 to 5 yr. The monthly rainfall across the state and the concentrations of Hg in wet-only and bulk deposition increased by a factor of 2-3 during the summertime "wet season" (May-October). These parallel increases in rainfall amount and Hg concentration resulted in 5-8-fold increases in rainfall Hg deposition during the wet season. The annual volume-weighted Hg concentrations ranged from 14 +/- 2 to 16 +/- 2 ng/L across southern Florida, and the annual rainfall Hg fluxes ranged from 20 +/- 3 to 23 +/- 3 micrograms m-2 yr-1. The weekly integrated particulate Hg concentrations in southern Florida were low (4.9-9.3 pg/m3) and did not exhibit strong seasonal variability. Considering the pronounced seasonal pattern in rainfall Hg deposition, the relatively uniform summertime rainfall Hg concentrations, and the low concentrations of particulate Hg, we conclude that processes other than particulate Hg transport and scavenging govern rainfall Hg deposition in southern Florida. We hypothesize that long-range transport of reactive gaseous Hg (RGM) species coupled with strong convective thunderstorm activity during the summertime represents > 50% of the Hg deposition in southern Florida. Model calculations indicate that local anthropogenic particulate Hg and RGM emissions account for 30-46% of the summertime rainfall Hg deposition across the southern Florida peninsula.

A feasibility study of the evaluation of the Florida breast cancer early detection program using the statewide cancer registry.

In Florida, a Center for Disease Control and Prevention (CDC)-funded initiative of the Florida Department of Health has targeted socio-economically disadvantaged women for breast and cervical cancer screening. Since 1995, over 12,000 women aged 50-64, within 200% of the federally defined poverty level, with no health insurance, and living in metropolitan catchment areas in Florida, have been screened by the Florida Breast and Cervical Cancer Early Detection Program (BCCEDP). This was a matched cohort cross-sectional analysis of a cohort study of Florida women with breast cancer using the Florida incident cancer registry, the Florida Cancer Data System (FCDS). The study evaluated the hypothesis that there would be no difference in the stage at diagnosis between breast cancer cases in the BCCEDP-screening program and breast cancer cases not diagnosed in the screening program. After linking the BCCEDP records with the FCDS, BCCEDP-screened cases were matched on gender, age, race, ethnicity, and other variables with five groups of FCDS breast cancer cases not screened by BCCEDP to control for demographic and socio-economic factors. Breast cancer cases diagnosed in BCCEDP were significantly more likely to be diagnosed at later stage than non-BCCEDP breast cancer cases in the five matched groups. The BCCEDP is not purely a screening program since it also caters to symptomatic women in the indigent population, therefore these finding were expected. In fact, 71% of the BCCEDP cases were symptomatic at the time of screening/diagnosis and 53% were late-stage diagnosed. These findings show that BCCEDP is indeed servicing its targeted population of medically under-served and symptomatic women in Florida. Furthermore, despite limitations, this study illustrates the potential collaboration between cancer registries and breast cancer screening programs for quality control purposes.

Chloroplast and microsatellite DNA diversities reveal the introduction history of Brazilian peppertree (Schinus terebinthifolius) in Florida.

Brazilian peppertree (Schinus terebinthifolius) is a woody perennial that has invaded much of Florida. This native of northeastern Argentina, Paraguay, and Brazil was brought as an ornamental to both the west and east coasts of Florida at the end of the 19th century. It was recorded as an invader of natural areas in the 1950s, and has since extended its range to cover over 280 000 ha. Our goals were to understand the history of this invasion, as one step toward understanding why this exotic was so successful, and ultimately to improve development of biological control agents. We sampled plants from the native and exotic ranges, particularly Florida, and genotyped these individuals at nuclear and chloroplast loci. Nuclear microsatellite and cpDNA loci reveal strong genetic population structure consistent with limited dispersal in the introduced and native ranges. Bayesian clustering of microsatellite data separates the east and west coast plants in Florida into distinct populations. The two chloroplast haplotypes found in Florida are also concordant with this separation: one predominates on the east coast, the other on the west coast. Analysis of samples collected in South America shows that haplotypes as distinct as the two in Florida are unlikely to have come from a single source population. We conclude that the genetic evidence supports two introductions of Brazilian peppertree into Florida and extensive hybridization between them. The west coast genotype likely came from coastal Brazil at about 27 degrees south, whereas the east coast genotype probably originated from another, as yet unidentified site. As a result of hybridization, the Florida population does not exhibit low genetic variation compared to populations in the native range, possibly increasing its ability to adapt to novel environments. Hybridization also has important consequences for the selection of biocontrol agents since it will not be possible to identify closely co-adapted natural enemies in the native range, necessitating more extensive host testing.

Impact of immigration on health and human services: Florida's experience.

Florida has been the destination for large numbers of immigrants fleeing political persecution or economic hardships. Cubans and Haitians have been two of the largest immigrant groups arriving and settling in Florida. Both have received national and local attention. This article describes the immigration experience of Haitians and Cubans in Florida. The descriptions emphasize the differences between these two groups in their adjustment to life in south Florida. The article also addresses Florida's reaction to federal policies regarding immigration and highlights Florida's struggle to meet the service needs of these immigrant populations. Fiscal impacts of immigration are quantified in several service categories, including education, social services, health care, and criminal justice. Florida's action based on the documentation of the immigration fiscal impact is explained. Finally, how the state allocated the $18 million in federal funding provided as a response to Florida's documented impact is covered.
