Human activities very obviously impact the environment. From pollution, to deforestation, to the introduction of invasive species, human activities often cause noticeable effects within an ecosystem. Knowledge of the cause and effect relationship between an action and its consequences makes up the bulk of effects pathways management. Describing land development proposals using data concerning Effects Pathways is often employed to minimize the harmful effects of developing that land. This data includes a list of the activities involved, the kinds of cause-and-effect interactions that are known to exist, and the methods by which stressors finally result in consequences in the environment. This study aims to uncover and catalog the resource needs for every life stage of 64 imperiled plant species, some of them being endemic to the state of Florida. This data could then be used to identify cause-and effect relationships between Human actions and the wellbeing of these endangered species. Most data collected was obtained by way of ECOS, most notably through the use of the "Five-year review" papers when they were available. Additional data was collected through the use of various peer-reviewed articles. Raw data in the form of papers, articles, and reports were mostly processed visually and the pertinent data from the raw data was recorded manually. This was done through careful reading and note-taking. The resource needs and life stage data was then added into a spreadsheet where data for each plant was recorded. From the data collected from the life stages and resource needs of the plant species used in this study several trends between the species involved arose. These trends Include low genetic diversity, persisting only in habitats exclusive to Florida, poor defenses against competing or invasive species, and benefitting from regular wildfires. The information gathered in this study is sure to be instrumental in allowing the effects pathways management team of the USFWS to effectively and efficiently manage and maintain Florida's ecosystems through understanding of their life cycles, resource needs, and the effects that certain actions or inactions from humans cause on them. This information allows us to understand not only the relationship between humans and the ecosystem, but the relationships between the organisms that live in them as well. There are several instances in which one plant on the list often lives near or relies on another plant from the list for its survival. This shows that the act of protecting one species is often the same as acting to protect the other species that rely upon it. This holistic approach to ecosystem management via the protection of one species that benefits several others can be very effective in ensuring the survival of several uniquely Floridian ecosystems.

The pandemic and resulting shift to remote work stressed the importance of distance library services. As librarians explored different modes of engagement, embedded librarianship became increasingly important but also more complicated than before. While there is a wealth of literature on embedded librarianship, few authors agree on how to define it or discuss its specific challenges during the pandemic. This paper will present the experiences of two academic librarians working in different departments at the same institution, informed by the literature; the authors will highlight the complexity of embedded librarianship during this unique time while addressing challenges and offering recommendations.

Contemporary America faces dep-seated problems -- not least because so many Americans have lost respect for their own electoral system and democratic institutions. America suffers too from unrelenting right-wing hyperbole in respect of significant social issues, including their conviction that only they understand, and value, freedom. Because of Australia's restrictive responses to the COVID-19 pandemic, Florida's Governor Ron DeSantis -- a potential Presidential candidate - denigrates Australia as 'not a free country; not a free country at all'. Australians may dismiss Governor DeSantis's comments as laughable, but a chorus of hard right comments in support of his view invites a comparison of the different ways in which 'freedom' is understood in Republican America and in Australia. One consequence of DeSantis's conception of 'freedom' is the extraordinary American death rate from the Covid-19 pandemic, which in the case of Florida -- which DeSantis celebrates as the 'freeest State' -- stood at about 48 times the Australian rate when he scorned Australia as indistinguishable from communist China. The roots of America's present malaise are to be found in the evolving (mis)understandings of a set of keywords including 'freedom', 'democracy', 'tyranny', 'individualism', and 'society'. The understanding of these keywords has now been impoverished by the radical right, and the Australian pandemic response was in fact designed to give freedom from the 'freedom' that the Republican right now eulogises. This paper therefore aspires to show that economic philosophy needs to be apprehended not only in terms of theoretical discourse, but also in terms of the ways in which its practical consequences are currently being manifested.

Rock coring is an essential method of geotechnical site characterization for foundations supported by rock, in which three possible phases of operation exist: inefficient, optimized, and destructive. When operating within the optimized phase, core recoveries and the rock quality designation reflect the strata encountered. However, the optimized phase is rarely achieved in practice, leading to deficiencies in strength assessment and geotechnical site characterization. This paper identifies the operational limits that separate each phase of rock coring by using measuring while drilling (MWD) and quantifies the increased energy that results from an inadequate depth of cut (Phase 1), the effects of breaking rock particles into smaller sizes, and the damage that occurs to core specimens from increased frictional resistance (Phase 3), as well as the effect rock strength and bit geometry have on mechanical efficiency. Drilling parameter interdependencies are discussed and detailed guidelines to assess rock strength in situ via MWD are provided. Finally, recommended coring guidelines are established through MWD which optimize the quantity and quality of strength assessments collected to improve geotechnical site characterization.

Increasing concerns about automation of work raise the question what the demographic components are that promote the spread of technology. What is the relationship between the presence of immigrants and automation? This paper is divided into two parts: an empirical investigation and a historical case study. Empirically, we use data from the International Federation of Robotics and the American Community Survey to show that US counties that have a higher share of foreign-born population, especially from Latin American countries (low-skilled), but also from China and India (high-skilled), exhibit less robot exposure, which confirms the intuition that regions with more low-skilled and high-skilled immigrant workers with low wages and low organizational clout provide employers with alternatives to robots. The case study of the Florida sugarcane producers shows that the availability of low-skilled foreign workers can diminish incentives to mechanize production unless protests/ lawsuits make them more expensive.

Although there is extensive work related to design and implementation of model-driven optimal groundwater management, evaluation of the performance of those models is less reported. This hinders transferability of lessons learned and wide adoption of specific policies. This paper reports a study designed to evaluate the effectiveness of a real-time optimal groundwater management tool, optimized regional operations plan (OROP), used in the Tampa Bay region (located on the west coast of Florida in the United States) since 1998. The overarching question in this study is how different groundwater levels would have been at monitoring sites if such an operational decision-supporting tool was not implemented. The proposed framework is comprised of multiple steps, including generating a non-OROP groundwater pumping scenario that would have happened without the decision support tool in place, running a modified optimization model in retrospective mode, and comparing water level between OROP-based and non-OROP–based pumpage scenarios. The framework is applied to historical data in the past decade (2010–2019). In generating an alternative pumpage scenario, realistic model constraints (e.g., pump capacity, pipeline hydraulics, and network) were used to generate wellfield pumpage to meet demands. Wellfield pumpage is then disaggregated at individual wells. Differences in resulting water levels at monitoring wells, at multiple timescales, between the OROP and non-OROP pumpage scenarios were calculated. Results reveal that although at a weekly timescale the effectiveness of OROP seems minimal over the region, the cumulative effectiveness at the monthly and annual timescales is remarkable. It is also found that benefit of using OROP is even higher during dry seasons when groundwater levels are more critical in maintaining wetland health. The proposed framework presented in this study can be applied to other areas in evaluating groundwater management strategies. [ABSTRACT FROM AUTHOR]

This paper provides a summary of published sea level archives representing the past position of sea level during the Last Interglacial sea level highstand in the Bahamas, Turks and Caicos, and the eastern (Atlantic) coast of Florida, USA. These data were assembled as part of a community effort to build the World Atlas of Last Interglacial Shorelines (WALIS) database. Shallow marine deposits from this sea level highstand are widespread across the region and are dominated by carbonate sedimentary features. In addition to depositional (constructional) sedimentary indicators of past sea level position, there is also evidence of erosion, dissolution, and/or subaerial exposure in places that can place an upper limit on the position of sea level. The sea level indicators that have been observed within this region and attributed to Marine Isotope Stage (MIS) 5e include corals, oolites, and other coastal sedimentary features. Here we compile a total of 50 relative sea level indicators including 36 in the Bahamas, three in West Caicos, and a remaining 10 for the eastern seaboard of Florida. We have also compiled U-Th age data for 24 fossil corals and 56 oolite samples. While some of these archives have been dated using U-Th disequilibrium methods, amino acid racemization, or optically stimulated luminescence, other features have more uncertain ages that have been deduced in the context of regional mapping and stratigraphy. Sedimentary archives in this region that constrain the elevation of the past position of sea level are associated with uncertainties that range from a couple decimeters to several meters. Across the Bahamas and on West Caicos, one of the observations that emerges from this compilation is that estimation of sea level position in this region during Marine Isotope Stage 5e is complicated by widespread stratigraphic evidence for at least one sea level oscillation. This evidence is defined by submarine features separated by erosion and subaerial exposure, meaning that there were likely multiple distinct peaks in sea level rather than just one. To this end, the timing of these individual sea level indicators becomes important when compiling and comparing data across the region given that different archives may have formed during different sub-orbital peaks in sea level.

Citrus greening, also called Huanglongbing (HLB), has affected citrus production globally. In Florida, the disease has decimated citrus production area and overall fruit yields. Emerging results show that some nutrients applied in a balanced and constant nutrition (BCN) program alleviate tree stress by improving root health, canopy size and tissue nutrient concentration. In this paper, we discuss the current strategies for managing citrus in Florida, and roles of macro- and micronutrients in citrus and other crops. Further, we discuss the role of macro- and micronutrients in potentially restoring root health and tree performance. We wrap up by discussing future research opportunities on the health and nutrition of HLB-affected citrus trees. [ABSTRACT FROM AUTHOR]

The 2015 Peril of Flood Act mandates that municipalities in Florida, USA consider sea level rise (SLR) in the coastal element of the comprehensive plan. Because the mandate lacks specificity, planning actors have broad discretion on how to respond. This paper examines how state, regional, and local level actors are implementing the mandate through a case study of the Tampa Bay region. Documents and interviews reveal that state agency staff provided inconsistent compliance guidance. Regional organizations developed credible planning intelligence and promoted collaboration and shared learning. Local planning actors, led by champions, utilized the mandate as political cover and a window of opportunity to pursue progressive planning. These champions were committed to technically competent planning practice and a moral duty to plan for SLR. The analysis reveals the importance of a top-down mandate to spur SLR planning in Florida when paired with regional capacity building and local level progressive champions. [ABSTRACT FROM AUTHOR]

An academic research institution and a corporate hospital system formed a new graduate medical education (GME) consortium. The consortium objectives were to increase the scholarly activity of the residents and fellows in a national hospital system's GME residency program to match the requirements set forth by the Accreditation Council for Graduate Medical Education. A GME librarian position was created specifically to serve the GME research programs at Florida area hospitals to help with this objective. This paper describes the experience, activities, and lessons learned from the creation of an entirely new GME library program and librarian position for a nine-hospital region in Florida.

Healthcare resource availability is potentially associated with COVID-19 mortality, and the potentially uneven geographical distribution of resources is a looming concern in the global pandemic. Given that access to healthcare resources is important to overall population health, assessing COVID-19 patients' access to healthcare resources is needed. This paper aims to examine the temporal variations in the spatial accessibility of the U.S. COVID-19 patients to medical facilities, identify areas that are likely to be overwhelmed by the COVID-19 pandemic, and explore associations of low access areas with their socioeconomic and demographic characteristics. We use a three-step floating catchment area method, spatial statistics, and logistic regression to achieve the goals. Findings of this research in the State of Florida revealed that North Florida, rural areas, and zip codes with more Latino or Hispanic populations are more likely to have lower access than other regions during the COVID-19 pandemic. Our approach can help policymakers identify potentially possible low access areas and establish appropriate policy intervention paying attention to those areas during a pandemic. • The temporal variations in the spatial accessibility of COVID-19 patients to ICU beds in Florida are examined. • A spatial accessibility method, spatial statistics, and a statistical method are performed. • Rural areas are more likely to be a low access area across all time periods. • Areas with more Latino or Hispanic populations are likely to have low access during the early and spreading periods.

Recently, local governments experienced unprecedented challenges to their recycling programs and are looking to alternative forms to meet their sustainability goals. Traditionally, waste management policies focus on using a mass-based recycling rate to promote and measure sustainability, however that metric inadvertently promotes recycling over source reduction. Here, we present a metric which measures a community's greenhouse gas (GHG) and energy use footprints for their consumed and end-of-life material streams. Using materials and waste statistics for Florida as an example, we estimated the consumed and discarded masses of 24 materials in 2018. We developed methods and used existing (i.e., WARM, literature) lifecycle assessment data to measure upstream and end-of-life environmental footprints of these materials. The total upstream footprints were approximately 12 and 10 times larger than the end-of-life GHG emissions and energy use footprints, respectively, indicating the need for sustainable materials management application. Mixed paper, cardboard, mixed construction and demolition (C&D) materials had the largest lifecycle footprints. We then use these data to illustrate a method for local governments to apply the alternative metric referred to as the lifecycle footprint reduction target. We demonstrate this target's application in Florida using a hypothetical 20% footprint reduction and provide approaches which focus on increasing the source reduction and recycling potentials of key materials to meet the target. The approaches included a junk mail ban, food donation mandate, cardboard takeback mandate, and building deconstruction mandate and were evaluated for their feasibility in meeting the target; the building deconstruction and the food donation mandate resulted in the greatest and least progress, respectively, toward meeting the target. These approaches provide local government a baseline for continued progress toward SMM application. Implications: Consumer consumption of manufactured products – the packaging for our food and beverages, the products in our homes and offices, the vehicles we drive, and the buildings we live and work in – ultimately must be discarded at the end of their useful life. It is through the management of residential and commercial solid waste that local governments face the consequences of society's materials consumption. Thus, not surprisingly, materials conservation efforts at the government level focus primarily on efforts to recycle waste and divert these materials from landfill disposal. Here we examine a concept whereby local governments – normally charged with collecting and managing residential and commercial waste, and thus setting waste recycling targets – expand their thinking to include all life cycle phases for the materials consumed and discarded in their jurisdiction. In doing so, local governments can now shift from a waste management to a lifecycle-oriented perspective and expand beyond just managing waste to managing materials. [ABSTRACT FROM AUTHOR]

This paper aims to create a new hybrid ensemble data mining model to predict the Salmonella presence in agricultural surface waters based on the combination of heterogeneous ensemble approach for feature selection, clustering, regression, and classification algorithms. The data set for this study was collected from six agricultural ponds in Central Florida consisting of 23 features with 540 instances (26 Salmonella positive and 514 Salmonella negative). The model consisted of three stages. Initially, a heterogeneous ensemble feature selection (HEFS) approach was applied to select top features. Then, the k‐means clustering algorithm was implemented to remove misclassified cases from the data set. Finally, classification and regression algorithms, including support vector machine (SVM), Naïve Bayes (NB), Artificial Neural Network (ANN), Random Forest (RF) with soft voting approach were applied to the preprocessed data set to predict the Salmonella presence in agricultural surface waters with the amount of test set (20%). These algorithms were combined in 10 different ensemble models through the soft voting approach. The performance of these hybrid ensemble models was also evaluated. The ensemble ANN + RF model achieved the highest performance and outperformed all other single and ensemble models based on Area under the ROC Curve (AUC) (0.98) and prediction accuracy (94.9%). The findings emphasize the validity of our hybrid ensemble model which encourages researchers to predict Salmonella presence in agricultural surface waters. [ABSTRACT FROM AUTHOR]

Recent scholarship shows that eligible voters in neighborhoods home to many arrested and incarcerated individuals vote at lower rates than those in less-affected neighborhoods. Little work, however, has investigated how this turnout gap might be counteracted. This paper uses Amendment Four, a 2018 Florida ballot initiative that promised to re-enfranchise most individuals whose voting rights had been revoked due to a felony conviction to investigate whether this turnout disparity can be narrowed by a ballot initiative of particular significance to communities most affected by incarceration. Using prison release records, I identify the neighborhoods and households where formerly incarcerated individuals live and assess the voting history of their neighbors and housemates. I find no evidence that Amendment Four increased these voters' turnout in 2018 relative to other voters. While ending felony disenfranchisement is necessary, closing the turnout gap resulting from histories of policing and incarceration will require greater investment and engagement.

Pond irrigation water comprises a major pathway of pathogenic bacteria to fresh produce. Current regulatory methods have been shown to be ineffective in assessing this risk when variability of bacterial concentrations is large. This paper proposes using mechanistic modeling of bacterial transport as a way to identify improved strategies for mitigating this risk pathway. If the mechanistic model is successfully tested against observed data, global sensitivity analysis (GSA) can identify important mechanisms to inform alternative, preventive bacterial control practices. Model development favored parsimony and prediction of peak bacterial concentration events. Data from two highly variable surface water irrigation ponds showed that the model performance was similar or superior to that of existing pathogen transport models, with a Nash-Sutcliffe efficiency of 0.48 and 0.18 for the two ponds. GSA quantified bacterial sourcing and hydrology as the most important processes driving pond bacterial contamination events. Model analysis has two main implications for improved regulatory methods: that peak concentration events are associated with runoff-producing rainfall events and that intercepting bacterial runoff transport may be the best option to prevent bacterial contamination of surface water irrigation ponds and thus fresh produce. This research suggests the need for temporal management strategies. IMPORTANCE Preventive management of agricultural waters requires understanding of the drivers of bacterial contamination events. We propose mechanistic modeling as a way forward to understand and predict such events and have developed and tested a parsimonious model for rain-driven surface runoff contributing to generic Escherichia coli contamination of irrigation ponds in Central Florida. While the model was able to predict the timing of peak events reasonably well, the highly variable magnitude of the peaks was less well predicted. This indicates the need to collect more data on the fecal contamination inputs of these ponds and the use of mechanistic modeling and global sensitivity analysis to identify the most important data needs.

In the spring of 2006 wild flamingos returned to Florida, though not to the places their kind had inhabited 100 years and more ago at the southern edge of the Everglades and the Florida Keys. Instead this group of flamingos alighted 80 miles northward in Palm Beach County's Stormwater Treatment Area 2 (STA-2), a human-made facility for filtering anthropogenic pollutants from storm runoff. This paper takes the return of wild flamingos to Florida as a case for thinking through haunting, ruination and encounters in what I call 'the ordinary Anthropocene': the ongoing, everyday more-than-human relationships, actions and less-than-planetary assemblages through which the Anthropocene is sensed and lived. After setting out a case for thinking with haunting, ruination and encounter as a way of making sense in the ordinary Anthropocene, I trace three interwoven narrative threads that unspool from the encounter with the STA-2 flamingos: First, I trace the transfiguration of living wild flamingos into idealised symbols of tropical dreamworlds over the 20th century. This leads me sideways to the present-absence of flamingos in the mid-century writings of Rachel Carson and through her backwards to John J. Audubon and the genocidal ruinations of the 19th century as they flicker in the margins of his ornithological writings. I end by returning to the present, to the encounter with STA-2 flamingos in the ongoing moment of living with others in the late capitalist ecologies of south Florida. The conclusion considers what might be taken forward, into the uncertain future, from this telling. [ABSTRACT FROM AUTHOR]

As part of ongoing efforts to understand, document, and conserve the flora of southeastern North America, we propose two new species, the recognition of a usually synonymized variety, the acceptance of two species of Waltheria as being present in peninsular Florida, taxonomic acceptance of a sometimes deprecated species transferred with a new name into a different genus, and we clarify the distribution and ecology of a species. In Carex (Cyperaceae), we re-analyze infrataxa in Carex intumescens and recommend the recognition of two varieties, a taxonomic schema first proposed in 1893, but usually not followed in the 128 years since. In Euphorbia (Euphorbiaceae), a careful assessment of south Florida material of Euphorbia subg. Chamaesyce sect. Anisophyllum subsect. Hypericifoliae reveals the need for taxonomic changes to best classify endemic representatives of this group, resulting in the naming of a new species, and a new name at species rank in Euphorbia for a taxon first named in Chamaesyce and sometimes subsequently treated at only varietal rank in Euphorbia. Chamaecrista deeringiana (Fabaceae, subfamily Caesalpinioideae) has been repeatedly misinterpreted to include two different and disjunct population systems with differing morphologies and habitats, which are here interpreted as separate species, one newly named and the other Chamaecrista deeringiana returned to its original and narrower interpretation as a south Florida endemic. Waltheria (Malvaceae) has sometimes been interpreted as being represented in Florida by a single taxon, Waltheria indica, but we disentangle the concepts of the widespread W. indica and the West Indian W. bahamensis and clarify that both are present in the southeastern United States. We reconsider the occurrence and habitat of Toxicoscordion nuttallii (Melanthiaceae) in three states in which it has been reported as a rare species, Mississippi, Missouri, and Louisiana, and remove it from the Mississippi flora as a garbled and false report. In Louisiana, its occurrence in calcareous prairie complexes limits its potential occurrence in the state to a specialized and rare habitat, but careful exploration of habitat remnants may result in the discovery of additional populations. Taxonomic studies and re-assessments of this kind are critical in laying the best scientific foundation for regulatory, policy, and land conservation decisions. This paper names or makes the case for the renewed acceptance of six species with range-wide conservation concern: one Critically Imperiled (G1 – Euphorbia ogdenii), one Imperiled (G2 – E. hammeri), and four Vulnerable (G3 – E. garberi, E. porteriana, Chamaecrista deeringiana, C. horizontalis).

Understanding tropical cyclone wind speed decay during the postlandfall stage is critical for inland hazard preparation. This paper examines the spatial variation of wind speed decay of tropical cyclones over the continental United States. We find that tropical cyclones making landfall over the Gulf Coast decay faster within the first 24 h after landfall than those making landfall over the Atlantic East Coast. The variation of the decay rate over the Gulf Coast remains larger than that over the Atlantic East Coast for tropical cyclones that had made landfall more than 24 h prior. Besides an average weaker tropical cyclone landfall intensity, the near-parallel trajectory and the proximity of storms to the coastline also help to explain the slower postlandfall wind speed decay for Atlantic East Coast landfalling tropical cyclones. Tropical cyclones crossing the Florida Peninsula only slowly weaken after landfall, with an average of less than 20% postlandfall wind speed drop while transiting the state. The existence of these spatial variations also brings into question the utility of a uniform wind decay model. While weak intensity decay over the Florida Peninsula is well estimated by the uniform wind decay model, the error from the uniform wind decay model increases with tropical cyclones making direct landfall more parallel to the Atlantic East Coast. The underestimation of inland wind speed by the uniform wind decay model found over the western Gulf Coast brings attention to the role of land–air interactions in the decay of inland tropical cyclones.

Despite the excellent research on incivility in social spaces, it is unclear if this pattern of meanness holds true in more personal communication such as email. Drawing on an original sample of 2,509 e-mails sent to Florida Governor Jeb Bush in response to his efforts to reinsert the hydration and nutrition tubes of Terri Schiavo, we analyze how individuals differentially use (in)civility and emotional expression in their claimsmaking. We find that emails sent to Bush about the Schiavo case are largely polite, even when individuals' disagreed with Bush's intervention on Terri's behalf. At the same time, we find a lot of emotional expression in the emails, and that the first emotional expression typically was negative. In order to better understand the relationship between (in)civility and emotion, we qualitatively analyze the 383 emails containing incivility, and find that individuals directed their negative emotional expressions at different targets. Additionally, we see different patterns in how negative emotional expressions are paired with uncivil communication according to the target. Emailers expressing negative emotions and incivility at Bush largely criticize him for violating individual rights, and, nearly half, blast him for prioritizing the Schiavo case over other problems facing the state. In contrast, emailers using uncivil language and negative emotional expressions at Terri's husband and a prominent judge try to persuade Bush to hold one or both of these men accountable for Terri's death. We conclude the paper by underscoring the utility in analytically distinguishing emotional expression from (in)civility. [ABSTRACT FROM AUTHOR]

Florida passed legislation in 2013 that exempted many students from developmental education, and required colleges to implement new instructional modalities for optional developmental education courses. This paper uses an economic model of remediation to examine how changes in college course taking before and after the reform altered costs to completing introductory college-level courses in math and English for students and institutions, and whether cost savings differ by racial/ethnic subgroup. We also take into account changes in short-term costs relative to course completion rates to examine whether the reform is cost effective overall. We find that the total cost per completer (including costs to both students and institutions) decreased after the reform by $894 in English and $1851 in math. This resulted in efficiency gains of 34% in English and 30% in math. The results from Florida provide promising evidence that statewide developmental education reforms may be an effective mechanism for reducing costs to students and institutions. Reform efforts may also help to reduce racial/ethnic gaps in the costs to gateway completion in both subject areas, which has important implications for equity. [ABSTRACT FROM AUTHOR]

In this volume, studies springing from a BMAA symposium held in Salt Lake City, Utah, in April 2019 are presented. Although most studies of neurotoxicity consider the effects of BMAA as an isolated molecule, it is now known that environmental exposures can be to a combination of BMAA-related molecules, including enantiomers, isomers, other co-occurring cyanotoxins, and BMAA carbamates. Within the body, BMAA may exist in equilibrium with α- and β-carbamates formed in the presence of bicarbonate. BMAA and its isomers 2,4-DAB and AEG, accumulate over decades in biocrusts and persist at depths in soil profiles of the Gulf deserts. In Florida, releases of cyanobacterially ladened water from Lake Okeechobee can extend into coastal environments where diatoms and possibly dinoflagellates also produce BMAA and isomers in addition to brevetoxins. Along the African Lake Chad, neurotoxic risks from consumption of dried cyanobacterial cakes may, however, be outweighed by their amino acid addition to otherwise protein-deficient diets. Discrepancies in the detection and quantification of BMAA from different laboratories likely originate in the use of different analytical methods. C-18 columns, used to study derivatized BMAA, can efficiently separate BMAA from its isomers in validated methods, while validation is not possible for HILIC columns in the study of underivatized BMAA, since they do not adequately separate BMAA from its isomer BAMA. The presence of BMAA dimers, metal adducts, and carbamates may result in underestimation of BMAA by mass spectrometry. BMAA research led to the identification of the dietary amino acid L-serine as a neuroprotective molecule. In animal and clinical trials, L-serine appears to slow neurodegeneration, although the modes of action are still under study. Based on zebra fish sensitivity to platinum-based chemotherapeutic agents, investigators have found that L-serine reduces reactive oxygen species (ROS) but does not protect auditory hybridoma cells from cisplatin. Another possible mode of action of L-serine, induction of autophagic-lysosomal enzymes, is also being explored. The hypothesis that cyanobacterial exposures in general, and chronic exposures to BMAA in particular, may prove to be risk factors for neurodegenerative illnesses has not been without critics. Emerging from the symposium, a multi-authored response to one such critical paper appears in this collection of articles. Instead of waiting until there is a conclusive proof of risk, the adoption of the "precautionary default principle," proposed by Ingvar Brandt and his colleagues in Sweden, is suggested. Avoidance of exposures to cyanobacterial blooms and other sources of BMAA is suggested, until further research indicates such precautions to be unnecessary. [ABSTRACT FROM AUTHOR]

Purpose The purpose of this paper is to investigate the stock market response to dividend announcements in high growth emerging markets of Gulf countries.Design/methodology/approach The sample includes 1,092 dividend announcements from 299 listed firms over the period 2010-2015.Findings In the environment where there is an absence of capital gain and income tax, the authors find some evidence for the stock price reaction that partly supports the signaling hypothesis. The findings show that the Gulf Cooperation Council (GCC) market is inefficient because of the leakage information before the announcement in bad news, and the delay of share price adjustment in good news. In addition, the authors report significant trading volume (TV) reaction in all the three announcements clusters, where dividends increase, decrease, and are constant, lending support to the hypothesis that the dividend change announcements have an impact on the TV response due to different investors’ preferences.Originality/value This is the first empirical paper on market reaction in share price and TV around dividend announcement using data for the majority of GCC countries.

Lake Okeechobee is Florida's largest lake, the largest lake in the Southeast United States, and the second largest lake contained entirely within the United States. The history of this inland sea is marked both by natural processes, and more recently human development and intervention. Adventurers can explore this behemoth of a waterway via the Lake Okeechobee Scenic Trail that enriches it, a part of the Florida National Scenic Trail. This paper synthesizes major natural and human-induced perturbations that shaped the lake and ultimately the trail that encircles it to create a narrative of Florida's great lake. The story of Lake Okeechobee is a story of battles, first between the land and sea, then between the lake itself and humankind. For the past few centuries Lake Okeechobee's natural perturbations in water flow and flooding resisted the control of man, until recently when man triumphed, managing to control the flow of water in and out of the lake. Unfortunately, with this new found control a new bioecological threat in the form of harmful algal blooms has emerged, which again threatens the health and livelihood of South Floridians. Currently there are new efforts that seek to restore Lake Okeechobee towards a more natural state in an effort to thwart the blooms. [ABSTRACT FROM AUTHOR]

With the increased emphasis on developing integrated models capable of simulating runoff through hydrologic systems that include hillslopes and wetlands, analytical solutions have become useful in analyzing and testing numerical models applied to both. An analytical solution in algebraic form is developed in this paper to describe a sinusoidal moisture profile migrating through a wetland or a hillslope, the magnitude of the peak runoff, and the phase lag. The solution is obtained for an instantaneous sinusoidal recharge signal, and results are expressed in terms of the basin geometry and flow resistance parameters. The analytical solution is used to verify the accuracy of a numerical model based on the implicit total variation diminishing Lax-Friedrichs (TVDLF) method. This method is used in the Regional Simulation Model (RSM) developed at the South Florida Water Management District (SFWMD) to simulate the complex hydrologic system of south Florida. The runoff peak, phase lag, propagation speed, and decay rate over a range of Péclet numbers are used in the comparison of analytical and numerical solutions. The numerical model using the TVDLF method is tested by applying to the Boggy Creek watershed in central Florida, and the wetland stormwater treatment area (STA)-3/4 in south Florida to simulate storm runoffs and water levels. Results show that the model using a general power-law equation to represent flow resistance, and a conceptual model consisting of a canallike drainage feature to represent rapid drainage can be used to simulate the hydrology in both the watershed and the wetland.

Over the past decade, research in the Aucilla River of northwestern Florida, USA, has focused upon understanding the geoarchaeological context of numerous formerly-terrestrial, now-inundated sinkhole spring sites and the landscapes surrounding them. Dozens of terminal Pleistocene and early Holocene-aged diagnostic artifacts have been recovered from this river, some in association with drowned terrestrial soils and intact dateable stratigraphy. Currently-terrestrial sites have thus far proven nearly undateable and are often conflated and deflated, but they provide evidence of extensive and resilient lifeways along the Aucilla River basin over thousands of years. The wealth of paleoenvironmental proxy data recovered from the drowned landscapes can help to explicate where, why, and how some sites have preserved while others have not. These data further suggest how people were adjusting to their changing environments over the more than 14,000 years they have been occupying the Aucilla River basin. This paper details the methods utilized to work on both sides of the waterline to reach a more holistic understanding of geoarchaeological context and human societies in the Aucilla River basin.

Criminal justice system fines and fees are a source of revenue for courts, district attorneys, probation departments, and other actors both inside and outside of the justice system. Because these departments rely on fine and fee revenue to partially fund their budgets, they may be incentivized to oppose reforms that would reduce fine and fee collections. Using budget documents from counties and a sample of municipalities in Florida and New York, the authors find that budget reports provide more detailed data on fines and fees than are available from other data sources, including information on which types of fines and fees are collected and how much revenue criminal justice fines and fees provide, both on a per-capita basis and as a share of the total jurisdiction budget. This paper presents a replicable methodology for future research in how to use local government budget documents to evaluate fine and fee collections. A larger, forthcoming study will use this methodology to examine fine and fee collections in five states. [ABSTRACT FROM AUTHOR]

Public opinion researchers often find changing attitudes about pressing public health issues to be a difficult task and even when attitudes do change, behaviors often do not. However, salient real-world events have the ability to bring public health crises to the fore in unique ways. To assess the impact of localized public health events on individuals' self-reported behavior, this paper examines Floridians' intentions to take preventative measures against the Zika virus before and after the first locally transmit- ted case of Zika emerged in Florida. We find that local and national media coverage of Zika increased significantly following its first transmission in the U.S. Critically, we also find that Floridians surveyed after this increase in media coverage were more likely to pay attention to Zika-related news, and self-report intentions to take protective action against the virus. These results suggest that behavioral intentions can shift as health threats become more proximate. [ABSTRACT FROM AUTHOR]

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal‐central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation‐related research. There are no copyright restrictions. Please cite this data paper when using the data in publications. We also request that researchers and teachers inform us on how they are using the data. [ABSTRACT FROM AUTHOR]

Traditional economic forecasts had consistently underestimated the hypergrowth of South Florida and its need for freshwater from the 1970s through the 1990s. It was hypothesized that the continued rapid growth of urban and farm water use into the 2000–2030 period would undermine efforts to restore the Everglades. To test this hypothesis, the corresponding author had hybridized two widely used regional economic modeling tools: the static, single-period Impact Analysis for Planning (IMPLAN); and the dynamic multiperiod Regional Economic Modeling Inc. (REMI) to forecast population and water use for the period from 2010–2030. In the present paper, these early forecasts are compared to actual census and water use counts for 2010 and 2015. Some of these early forecasts are found to be surprisingly accurate while others seriously overshoot the mark. The on-target forecasts validate the basic hybrid model while the other "deviant" forecasts measure the success of the radical antidrought policies and the region's economic reaction to the financial collapse. This retrospective provides a new metric for measuring actual changes in the paradigm of water consumption. [ABSTRACT FROM AUTHOR]

This paper describes the ecology and management of two flow-through created wetlands that, in turn, defined 30 years of research by Bill Mitsch, 20 years in Columbus, Ohio (1992–2012) and 10 years in Naples, Florida (2012−2022). The Olentangy River Wetland Research Park was built in several stages from 1993 through 2010. The first stage was the creation of dual 1-ha kidney-shaped wetlands primarily fed by pumped Olentangy River water. A pattern of inflow that depended on river stage was maintained for 17 years. The two experimental wetlands were established by planting one of the wetlands with a variety of wetland macrophytes and leaving the second wetland unplanted to ultimately determine whether human introduction of wetland plants matter in the long run. In addition to maintaining data collection for hydrology, water quality, and other functions, these wetlands and several others constructed on the 20-ha floodplain site were heavily used as was the mesocosm compound, mostly for short-term (2 to 3 year) experiments by graduate students. Another 20-ha created wetland complex, called Freedom Park Wetlands, was constructed in 2007–2008 in Naples, Florida, at an abandoned citrus grove, to seasonally treat urban stormwater runoff. During that wet season, the design calls for an average water detention time of 18 days. The wetland system included a 1.9-ha deepwater pond for temporary storage of the urban stormwater pulses from what is mostly an urban watershed, followed by 2.7 ha of shallower vegetated wetland ponds designed to sequentially improve water quality. Within each wetland, there are three deep-water cells and two shallow-water cells. The water eventually exits the treatment wetlands via a rectangular and travels diffusely through a restored bottomland forest to the Gordon River and ultimately toward Naples Bay and the Gulf of Mexico. During our tenure at Florida Gulf Coast University's (FGCU) Everglades Wetland Research Park, Freedom Park was a venue with active mesocosm experiments in a constructed mesocosm compound. Several of these mesocosm experiments were the subjects of master's theses from FGCU and doctoral dissertations from our partner, University of South Florida. Our students also contributed to the local environmental communities by giving tours of the Freedom Park wetlands and our mesocosm research. • This paper describes the ecology and management of two created wetlands. • The Olentangy River Wetland Research Park in Ohio, USA has provided data since 1994. • The Freedom Park wetlands in Florida, USA were constructed in 2007–2008. • Both wetlands offer ecosystem services (i.e. nutrient reduction and flood protection). • These wetlands provide the framework for thirty years of wetlands research.

A calibrated flow rating equation is often used to determine the flow rate through a hydraulic structure as a convenient and relatively inexpensive method to avoid the difficulties of direct discharge measurements in an open channel. In South Florida, there are hundreds of gated culverts, where accurate and quick estimation of discharge in real time is critical for effective water resource management. Flow through culverts under various conditions and geometries has been studied extensively; however, studies of stage-discharge relationships through gate-controlled culverts are rare and, to the authors' knowledge, not discussed in any open-channel hydraulics books, relevant journals, or design manuals. In this paper, two approaches to improve the stage-discharge relationships at gated culverts are presented, and case studies demonstrate their successful and cost-effective use: first, the application of computational fluid dynamics (CFD) for flow data simulation to supplement field measurements to resolve data limitations and, second, the application of dimensional analysis to improve gated-culvert rating equations. The proposed nondimensional flow rating approach is useful for data planning and consistency testing of hybrid data (field flow data and CFD results) and reduces the flow types occurring at a culvert, making the flow classification less complex while maintaining reasonable rating accuracy within 6% of field flow measurements.

When it comes to the creation of higher education policy, state legislators are challenged with addressing the diverse academic needs of college students enrolled across a spectrum of institutions. In this paper, we explore how 203 individuals at five rural‐serving colleges in Florida engaged in state‐wide developmental education (DE) reform using the theoretical framework of "situated cognition." Specifically, we ask whether the colleges implemented DE reform in unique ways that may have differed from their non‐rural counterparts and what their rationale was for doing so. Our work indicates that institutional culture and capacity generated a combination of strengths and constraints in how reform played out in a rural context. In some ways, a rural‐serving identity made colleges more flexible and better able to adjust their advising and curricular structures to comply with the mandates of SB 1720. But in other ways, rural‐serving institutions lacked the resources necessary to adequately support students and campus personnel through this dramatic transition toward new ways of providing DE. In looking toward the passage and implementation of future education reform, we call upon policymakers to consider more deeply the design of policies to ensure they support rural and non‐rural colleges alike.

Climate change is threatening an uncalculated number of archaeological sites globally, totaling perhaps hundreds of thousands of culturally and paleoenvironmentally significant resources. As with all archaeological sites, they provide evidence of humanity's past and help us understand our place in the present world. Coastal sites, clustered at the water's edge, are already experiencing some of the most dramatic damage due to anthropogenic climate change, and the situation is predicted to worsen in the future. In the face of catastrophic loss, organizations around the world are developing new ways of working with this threatened coastal resource. This paper uses three examples from Scotland, Florida, and Maine to highlight how new partnerships and citizen science approaches are building communities of practice to better manage threatened coastal heritage. It compares methods on either side of the Atlantic and highlights challenges and solutions. The approaches are applicable to the increasing number of heritage sites everywhere at risk from climate change; the study of coastal sites thus helps society prepare for climate change impacts to heritage worldwide.

Reinforced Concrete (RC) and Prestressed Concrete (PC) structures using conventional materials in aggressive exposure conditions are susceptible to corrosion. Non-corrosive reinforcement materials such as: Glass Fiber-Reinforced Polymer (GFRP) rebars; Carbon Fiber-Reinforced Polymer (CFRP) strands; Stainless-Steel (SS); and Epoxy-coated steel (ECS) reinforcing bars, are attracting attention as more appropriate options in concrete structures. This paper addresses a Life Cycle Cost (LCC) analysis that verifies the cost performance of four different alternative reinforcement bars for the design of a demonstration FRP-RC/PC bridge in Florida, namely Halls River Bridge (HRB). The four different alternatives to be compared are namely Carbon Steel (CS), SS, FRP, and ECS, and the analysis is performed over 100-years. Additionally, a Life-Cycle Assessment (LCA) is included in the analysis to investigate the environmental credentials of the four design alternatives. Cost sensitivity analyses over specific parameters are included. The parameters analyzed are: reinforcement cost, changes in chloride concentration levels over the bridge service life, and discount rate values. Conclusions and recommendations for standard practices and design of future alternative solutions are then presented. [ABSTRACT FROM AUTHOR]

The American Southeast saw the development of large ceremonial village centers, the coalescence of households, and monumental architecture integrated into village layout during the Middle Woodland period (ca. AD 1–600). These shifts toward more sedentary lifeways occurred independently of, and prior to, the domestication of plants across the Southeast. This paper examines the seasonality of monumental construction at the Garden Patch site located on the central Gulf Coast of Florida. This site contains evidence for rapid mound construction that followed a predetermined site plan. Here, we present oxygen isotope analyses of archaeological mollusk shells (Crassostrea virginica) to evaluate the seasonality and periodicity of monument construction. We conclude that mound construction occurred during the cooler months of the year. Ultimately, this contributes to an anthropological understanding of the development of these early ceremonial centers in the Southeast. [ABSTRACT FROM AUTHOR]

Diseases carried by mosquitoes and other arthropods endanger human health globally. Though costly, surveillance efforts are vital for disease control and prevention This paper describes an approach for strategically configuring targeted disease surveillance sites across a study area. The methodology combines risk index mapping and spatial optimization modelling. The risk index is used to identify demand for surveillance, and the maximum covering location problem is used to select a specified number of candidate surveillance sites that covers the maximum amount of risk. The approach is demonstrated using a case study where optimal locations for sentinel surveillance sites are selected for the purposes of detecting eastern equine encephalitis virus in a county in the state of Florida. Optimal sentinel sites were selected under a number of scenarios that modelled different target populations (horses or humans), coverage distances (0.5, 1.0, and 1.5 km), and numbers of sites to select (1–12). Sentinel site selections for the horse and human models displayed different spatial patterns, with horse sites located largely in the west-central region and human ones in the north-central. Minor amounts of spatial overlap between the horse and human sites were observed, especially as coverage distances and numbers of sites were increased. Additionally, a near linear increase in risk coverage was observed as sites were incrementally added to the scenarios. This finding suggests that the number of sentinel sites within the ranges explored should be based on the maximum that can be funded, since they provide similar levels of benefit.

Introduction: Church-based interventions have been shown to improve the dietary health of underserved populations, yet few studies have examined sustainability of health behavior change over time. This paper examines dietary outcomes over a 24-month period (baseline and 6, 18, and 24 months) for fruit and vegetable and fat consumption behaviors of African-American participants in the Health for Hearts United church-based intervention in North Florida.Study Design: This quasi-experimental, longitudinal trial was conducted from 2009 to 2012. Data were analyzed in 2018.Setting/participants: Six churches in a 2-county area (3 treatment, 3 comparison) were selected for the study using community-based participatory research approaches. Participants were African-American adults (aged ≥45 years; n=211 at baseline) randomly selected from the churches, stratified by age and sex.Intervention: Health for Hearts United intervention was developed by the 3 treatment churches. The 18-month intervention was implemented in 3 6-month phases, framed around 3 conceptual components, which included 4 types of programs and 4 key messages.Main Outcome Measures: Fruit and vegetable consumption was assessed using a single item (fruit and vegetable intake) and the National Cancer Institute Fruit and Vegetable Screener. Fat consumption was determined using a single item (fat intake) and the National Cancer Institute Fat Screener. Background characteristics included age, sex, educational level, and marital status.Results: Significant time effects only were found for daily fruit and vegetable intake (p<0.001), fat intake (p<0.001), and the Fat Screener (p<0.001) with dietary improvements in both treatment and comparison groups across the intervention phases. Fruit and Vegetable Screener results showed that time (p<0.001) and the interaction between time and treatment (p<0.01) were significant, with increases in fruit and vegetable consumption over time for both the treatment and comparison groups and with the increase differing between groups. Post hoc analysis revealed that the treatment group had greater increases in fruit and vegetable consumption than the comparison group between Phases 1 and 3 (p=0.03).Conclusions: Dietary behaviors of mid-life and older African Americans can be improved and sustained over 24 months using a church-based heart health intervention, with similar improvements noted for both comparison and treatment participants.Trial Registration: This study is registered at www.clinicaltrials.govNCT03339050.

• We investigate the contamination issue in SSR in Florida analyzing the audit data. • High reject rate in inbound streams is the main driver of the contamination issue. • Grit/fines/sweepings, mixed plastics, scrap metals are the main contaminants. • Contamination rates in glass and colored HDPE streams can be up to 45%. • None of the obtained 266 ONP and only 31.4% OCC samples meet the mill standards. The single stream recycling (SSR) program is a process in which all recyclable materials are deposited into a single collection bin. SSR has gained popularity in the U.S. due to its inherent abilities in waste collection, and specifically, in Florida, more than twenty counties have recently switched their recycling program from dual stream recycling (DSR) to SSR. Despite a more efficient collection process, mixing all recyclable materials into a single bin can lead to cross contamination even before reaching material recovery facilities (MRFs). This study aims to provide a better understanding of the sorting process and equipment in MRFs, and the impact of the SSR program on contamination rates in outbound materials that were processed through Florida's recycling systems. First, we investigate the audit data obtained from a currently operating MRF in Florida using mass flow analysis to identify the most problematic recyclable streams and the processes with low efficiency and high false separation rates. According to our results, the sorting rates of mixed paper, glass and plastics are under the industry standards. Moreover, we investigate the outbound contamination rates of 35 old corrugated cardboard (OCC) and 266 old newsprints (ONP) samples obtained from four currently operating MRFs in Florida. Based on the results, only 31.4% of OCC samples and none of the ONP samples were within the accepted mills' standards for contamination rates. This study provides valuable insights for lowering contamination and raising the end-product quality by identifying the problematic contaminants and processes in sorting and separation in MRFs.

• Solid waste management presents a policy venue of "green economic development." • There is a 0.4% SWMR employment growth upon a 1% point recycling rate increase. • Presence of strong environmental groups influences SWMR employment growth. • Labor force and unemployment rate result in scrap materials business growth. • Popular tourist destinations attract more recycling processing jobs in Florida. Recycling solid waste not only produces environmental and health benefits, but also generates economic benefit. This paper empirically evaluates the employment impact of Florida county recycling programs from 2000 through 2011, applying a fixed effects regression model. The results indicate that a one percentage point increase of county recycling rate leads to a 0.4% job growth in overall solid waste and recycling industry. However, the impact of recycling programs on green jobs are not uniform across the recycling subsectors: the effect is concentrated in the recycling processing sector while the solid waste collection sector and scrap materials businesses are unlikely to be influenced by county's recycling performance.

The baby boomer generation is aging, and many of the citizens that belong to this generation are retiring to Florida. Accordingly, Florida is expected to host one of the largest wealth transfers in history. And while the baby boomer population ages, our society is becoming more digitized. Things we traditionally did by pen and paper are now increasingly done by computer and keystroke, and wills are no exception. What was previously considered a document whose sacred nature could only be appreciated by the affixation of a handwritten signature at the bottom thereof, wills are now being drafted, signed, witnessed, and stored digitally. This Note analyzes Florida's recently enacted legislation, HB 409, that authorizes electronic wills and the remote witnessing of such wills. The analysis proceeds against a backdrop defining the term "electronic will" and explaining how electronic wills diverge from what society has traditionally deemed a will. I begin by explaining the policy reasons behind statutory will act formalities and the four functions that are served by these traditional formalities. I also discuss the various positions that courts have taken when deciding whether to admit any purported will to probate. Next, I discuss the three categories of electronic wills and the shortcomings that each of these categories faces with respect to the "Four Functions." After a brief discussion of how lawmakers and courts nationally and internationally have addressed the rise of electronic wills, this Note will turn the reader's attention to Florida's HB 409. This Note provides a summary of the legislation's main provisions and an analysis of its specific "functional" shortcomings. After June 1, 2020, Florida courts should expect an influx of digitally signed and remotely witnessed electronic wills. Florida courts should also be aware of the entirely new grounds for will contests that HB 409 creates. [ABSTRACT FROM AUTHOR]

While seldom integrated within coastal archaeological research in Southeastern North America, vegetation histories derived from palynological data offer valuable records of ancient landscape transformations driven by climatic flux, sea-level oscillations, and anthropogenic modifications. In this paper, we develop a paleo-historical-ecological reconstruction from preliminary analyses on fossil pollen assemblages preserved within marsh, hammock, and shell-midden soils at the Crystal River site (8CI1), a mound center on Florida's west-central coast occupied throughout the first millennium AD. When contextualized alongside paleoenvironmental records from western Florida and farther afield, our analysis suggests that the nature and timing of late-Holocene climatic changes varied little between different sub-regions of Florida's Gulf Coast, but also that manifestations of eustatic sea-level flux may have been highly localized.

• Demonstrates the use of LBSN to guide managers during natural disasters. • Method for content extraction and sentiment analysis from LBSN data. • Supervised machine learning techniques used to classify tweets. • Tweets joined with ACS 2017 to study the context where tweets emerge. • Longer, less re-tweeted content from less popular tweeters is likely to be useful. Location-based social networks like Twitter can relay not just what is happening but where. To enable efficient resource allocation during natural disasters, managers need to know what citizens are experiencing and where. During Hurricane Irma in 2017 in Florida over six million people were asked to evacuate. The hurricane caused widespread damage. We utilized geospatial and machine learning techniques to categorize geolocated tweets, which were both about Hurricane Irma and located within Florida. We employed sentiment analysis to classify tweets about damage and/or transportation into negative, neutral, or positive groups. We used the American Community Survey (ACS) 2017 geography to provide socio-economic context, and relied on a multinomial logit specification to examine which features of the tweet, tweeter, or location were likely to be associated with negative or positive sentiments. We found that longer tweets were more likely to have useful sentiment-based content. We also discovered that popular tweeters were likely to tweet positive sentiments, and that popular tweets were less likely to have useful information about the disaster. The ACS backdrop suggested that the likelihood of tweets with negative sentiments was higher in census block groups with younger families. The probability of tweets with useful positive or negative sentiments dropped in locations with higher property values or median rents. This paper offers a methodology for extracting information embedded within social media data, and suggests ways to develop a probability-based understanding of needs to guide disaster managers.

The federally endangered Schaus' swallowtail butterfly (Heraclides aristodemus ponceanus) inhabits protected subtropical dry forests on several islands in the northern Florida Keys. The larval and pupal stages are particularly vulnerable to native and non-native predators; however, few published research and reports have identified and quantified predator impacts. Video documentation presents an opportunity to corroborate anecdotal observations (predation events) with empirical evidence. Even in remote areas where electricity is not available, a video surveillance system powered with renewable energy can be used where monitoring wildlife would otherwise be difficult. We documented wildlife activity after captive-bred Schaus' swallowtail caterpillars were released in the field (Key Largo, USA). Video footage revealed two cardinals (Cardinalis cardinalis) captured three Schaus' swallowtail caterpillars within the first 8 h of release. Two caterpillars survived and were active at night. Five butterflies were identified flying onscreen, including the imperiled Florida white (Appias drusilla). A solar powered video surveillance system step-by-step guide with a material list and cost is presented in this paper. The materials and methods can be modified to suit researchers' needs. The video surveillance system can identify culprit species and quantify encounter rates between prey and predators remotely. [ABSTRACT FROM AUTHOR]

This paper assesses the impacts of physician-patient race-match, especially Black patients paired with Black physicians, on patient mortality. We draw on administrative data from Florida, linking hospital encounters from mid-2011 through 2014 to information from the Florida Physician Workforce Survey. Focusing on uninsured patients experiencing unscheduled hospital admissions who are conditionally randomly assigned to physicians, we find that physician-patient race-match for Black patients reduces the likelihood of within-hospital mortality by 0.28 percentage points, a 27 % reduction relative to the overall mortality rate. An alternative identification strategy relying on instrumental variables provides a similar finding. [ABSTRACT FROM AUTHOR]

The Stormwater Treatment Areas (STAs) are constructed wetlands used to reduce the total phosphorus (TP) level in water discharged to the environmentally sensitive areas of the Everglades Protection Area. Analysis of high temporal frequency TP data reveals that TP concentrations discharged from selected STA flow-ways exhibit diel and seasonal cyclic patterns and are most affected by discharge rate and water depth. The objective of this paper is to describe the diel TP pattern and evaluate the possibility of using it to reduce TP in STA discharge. The amplitude of diel TP pattern ranged from 0.7 to 1.5 μg L−1 (3–6% deviation from daily mean) at three flow-ways, peaking in the early afternoon and reaching lowest concentrations between midnight and 4 am. To assess the possibility of further reducing TP concentration discharged from the STAs by increasing the proportion of daily flow discharged at night when diel TP is at a minimum, a General Additive Model (GAM) was created with discharge rate, water depth, year, location, day-of-year, and time-of-day as covariates. While time-of-day was a statistically significant factor in the model (p < 0.001), its average marginal effect was smaller than all other significant model covariates: discharge rate, season, and water depth. Modeling suggests that within specific ranges of discharge rate and water depth, the opportunity exists to provide additional TP reduction in STA outflow by discharging a greater proportion of the daily flow at night when TP concentrations are lower. Further research is needed to quantify the effect of increasing nighttime flow on annual flow weighted mean TP. Additionally, an evaluation of the practicality and logistical cost required to redistribute flow is needed before attempting to take advantage of this natural cyclic pattern to improve STA TP retention. • A diel pattern in totla phosphorus (TP) was found in south Florida wetlands. • Peak diel TP occured between noon and 3 pm, a minimum concentration between midnight and 4 am. • Amplitude of diel pattern ranged between 0.7 and 1.5 μg L-1 TP or 3–6% from daily mean TP. • Under certain hydrologic conditions increasing the proportion of overnight flow could reduce TP in wetland discharge.

Longitudinal panel studies are effective strategies to assess the personal impact of child welfare work, as well as employment outcomes of workers over time. However, longitudinal studies encounter obstacles such as disproportionate attrition that threaten the validity of findings. This paper provides an overview of the Florida Study of Professionals for Safe Families (FSPSF), a 5-year longitudinal panel study of newly hired workers into the child welfare workforce. The purpose of this paper is three-fold: 1) describe the study methodology and recruitment and retention techniques for the FSPSF; 2) illustrate Estrada and colleagues' Tailored Panel Management framework (2014) through FSPSF methodological decisions; and 3) provide guidance and time estimates of key tasks for those interested in undertaking similar projects, with a particular focus on electronic data collection and communication strategies. Initial results are excellent – 84% of all eligible workers completed baseline surveys ( n = 1,451). At Wave 2 (6 months), 81% of those workers were retained, with preliminary findings of 84% retention of the original baseline respondents at Wave 3 (12 months). [ABSTRACT FROM AUTHOR]
