Title: CALCULATION AND COMPARISON OF THE FLOOD RISK POTENTIAL DUE TO RAINFALL EVENTS, HIGH TIDES, SEA LEVEL RISE, STORM SURGE AND THE COMBINATION OF ALL THE CASES ON THE EASTERN COAST OF FLORIDA.
Creator: Hoque, Mushfiqul S. M., Bloetscher, Frederick, Florida Atlantic University, Department of Civil, Environmental and Geomatics Engineering, College of Engineering and Computer Science
Abstract/Description: Coastal basins are particularly vulnerable to flood under multivariable conditions, such as heavy precipitation, high sea levels, tropical storm surge and rainstorms. These conditions should be considered to assess and manage flood risk better. In this research, a means to develop a watershed level screening tool to identify areas with potential for flooding due to high tides, rainfall events, sea level rise and combinations of all the cases was developed and compared to FEMA maps.

Show moreCoastal basins are particularly vulnerable to flood under multivariable conditions, such as heavy precipitation, high sea levels, tropical storm surge and rainstorms. These conditions should be considered to assess and manage flood risk better. In this research, a means to develop a watershed level screening tool to identify areas with potential for flooding due to high tides, rainfall events, sea level rise and combinations of all the cases was developed and compared to FEMA maps. The goal of the screening tool is part of a larger effort with respect to watersheds funded by the Florida Division of Emergency Management to enable local communities to reduce flood insurance costs through mitigation and resiliency efforts by means of risk assessment was undertaken. For this purpose, readily available data on topography, ground, and surface water elevations, tidal data for coastal communities, soils, and rainfall data were collected from the South Florida water management district, USGS, and NOAA. Firstly, using elevation data, soil data, and the Spatial Analyst tool, Arc-Hydro tools of ArcGIS, the drainage network, and soil storage capacity were determined. These results and rainfall data acted as inputs for Cascade to calculate the headwater height for all the cases for the selected basins. Using these headwater heights, several different probabilities of inundation were determined. This study will help manage and mitigate vulnerable areas and act as a tool to permit local agencies to develop means to address high-risk properties.

Show moreThe dramaturgy written by Cuban American, Puerto Rican, and Dominican American women propels Hispanic-Caribbean theater beyond the geographical borders of their islands, thus creating and nurturing, transnational cultural enclaves that support it while also transforming the cultural theatrical environment of the United States. This dramaturgy, with its themes and arguments, puts into practice the feminist and LGBTQ critical theories with a focus on minority groups in US society. This work analyzes Hispanic-Caribbean theater traditions from their origins to the transformations they undergo in the United States given the influence of the various Caribbean diasporas. The essential characteristics of this drama, written by women, lead to the creation of a new theater characterized by its hybrid and bilingual roots. This dramatic cultural transformation reveals the diversity and inclusion of ethnic, racial, sexual identities, and the myriad intersectionalities found in the diasporic island communities from which it takes flight.

Show moreIn the first essay, I examine how managerial opportunism affects corporate investment efficiency and, ultimately, firm performance. Prior research establishes corporate investment efficiency as a function of the firm’s information environment and internal governance. To measure managerial opportunism, I use an ex-ante firm level measure of managerial opportunism based on insider trading patterns and test its effects on investment efficiency and performance. Extant research associates opportunistic insider trading with opaque information environments about the firm and weak firm governance, making it an apropos proxy for opportunistic managerial behavior. Despite the clear establishment of opportunistic insider trading as an agency problem in the literature, it remains unanswered how the managerial insider trading decision’s economic irrationality might reflect a broader agency problem that affects firm investment policy and performance. I introduce competing hypotheses that managerial opportunism may positively associate with overinvestment through “empire building” and excessive risk taking at shareholders’ expense. On the contrary, manv agerial opportunism may lead to underinvestment through rent seeking behavior. My results show that managerial opportunism decreases firm investment efficiency and negatively affects accounting and stock performance. Further tests show that both the quality of the information environment and internal governance moderate the effects of managerial opportunism, providing a unique perspective on how insider trading policy and regulation can affect corporate investment policy.

Show moreMarine sponges are economically and environmentally valuable, but restoration, commercial, and biomedical demands exceed what wild populations and aquaculture can provide. In vitro culture of sponge cells is a promising alternative, but has remained elusive until recent breakthroughs involving improved nutrient medium M1 in two-dimensional culture. The advantages of three-dimensional over two-dimensional cell culture have been increasingly recognized. Here we report the successful 21-day culture of cells from the marine sponge Geodia neptuni using multiple three-dimensional cell culture methods: FibraCel© disks, thin hydrogel layers, gel micro droplets, and spheroid cell culture. These methods performed comparably to two-dimensional control cultures, and each method offers advantages for restoration or in vitro applications using sponge cells. Further optimization of these methods may lead to the ability to culture fully functioning sponges from dissociated, cryopreserved cells, which will reduce the need for wild harvest of sponge tissues for commercial, restoration, and biomedical purposes.

The survey assessed the following: Health care practitioner influence, Demographics, Stages of Change (SOC), anxiety and depression, perceived barriers to exercise, past and current exercise, and the constructs of the Theory of Planned Behavior (TPB). BCS who were older, had less education, did not exercise before diagnosis, were in the pre-contemplation and contemplation stages, and/or exhibited a low Perceived Behavioral Control had a lower intention to exercise. Incorporating the findings from this research into an intervention may assist with increasing intention to exercise among BCS.

Show moreThe purpose of this study was to explore several personal and work-related variables associated with posttraumatic growth (PTG) levels in professional firefighters employed in a large fire district in south Florida. First, the researcher identified common factors in professional firefighting research that were associated with PTG in firefighters (independent variables: perceived supervisor support, occupational stress, coping style, and sense of belongingness). Second, the researcher determined if there was a significant relationship between these independent variables and the dependent variable (PTG). Then the researcher examined whether demographic variables identified from the literature moderated PTG in professional firefighters, such as: number of years of service, trauma history, and military history prior to joining the fire service. The sample consisted of 63 firefighters in a large Fire District in south Florida. The sample size was small and underpowered, and the response rate was low due to the concurrent eruption of the COVID-19 pandemic during the data collection period. Descriptive statistics (means, standard deviations, internal consistency, range, and bivariate correlations) and multiple regression with hierarchical entry were used to test the six proposed hypotheses. The results indicated that perceived supervisor support had a statistically significant relationship with PTG levels in the sample (p = .027). Two of the controlling variables, prior trauma and military history, showed contradictory effects than was indicated in prior research. The present study’s sample reported lower incidences of prior trauma and military history prior to joining the fire service. Clinical implications, ideas for future research, practice, and policy were discussed.

Show moreIn this research, we propose to use deep learning to predict crimes in small neighborhoods (regions) of a city, by using historical crime data collected from the past. The motivation of crime predictions is that if we can predict the number crimes that will occur in a certain week then the city officials and law enforcement can prepare resources and manpower more effectively. Due to inherent connections between geographic regions and crime activities, the crime numbers in different regions (with respect to different time periods) are often correlated. Such correlation brings challenges and opportunities to employ deep learning to learn features from historical data for accurate prediction of the future crime numbers for each neighborhood. To leverage crime correlations between different regions, we convert crime data into a heat map, to show the intensity of crime numbers and the geographical distributions. After that, we design a deep learning framework to learn from such heat map for prediction. In our study, we look at the crime reported in twenty different neighbourhoods in Vancouver, Canada over a twenty week period and predict the total crime count that will occur in the future. We will look at the number of crimes per week that have occurred in the span of ten weeks and predict the crime count for the following weeks. The location of where the crimes occur is extracted from a database and plotted onto a heat map. The model we are using to predict the crime count consists of a CNN (Convolutional Neural Network) and a LSTM (Long-Short Term Memory) network attached to the CNN. The purpose of the CNN is to train the model spatially and understand where crimes occur in the images. The LSTM is used to train the model temporally and help us understand which week the crimes occur in time. By feeding the model heat map images of crime hot spots into the CNN and LSTM network, we will be able to predict the crime count and the most likely locations of the crimes for future weeks.

These concentrations pose a health risk and must be remediated for residential development. The objective of this study was to determine how arsenic concentrations vary spatially at a closed golf course poised for residential development. Groundwater and sediment arsenic concentrations were quantified and the controls on arsenic (As) mobility were characterized. The presence of nitrates and iron-(hydr)oxides at the studied golf course largely influenced putting greens having the least As in groundwater whereas roughs contained the most.

Marginal support was found for the main prediction that focusing on low level details rather than high-level meaning would lead individuals to rate false high-level relational construals as more valid, although this effect was found only for those reporting on a romantic relationship, but not a close friendship. Further, exploratory analyses examining potential interaction effects demonstrated the relative influence of partner concept-clarity and relationship satisfaction on patterns of psychological emergence.

The purpose of this research focused entirely on licensed CAMs in the State of Florida. CAMs are expected to be transformational leaders of community associations amidst emotionally charged environments with judicial dictates and strict rules and regulations. The impact of emotional intelligence on transformational leadership in CAMs has been under-researched and virtually ignored despite their critical role in community management. Two main theoretic lenses were used to guide this study of CAMs, Goleman’s focus on theory of emotional intelligence and Burns’ theory of transformational leadership.

Show moreCyber-Physical Systems (CPS) are physical entities whose operations are monitored, coordinated, and controlled by a computing and communication core. These systems are highly heterogeneous and complex. Their numerous components and cross domain complexity make attacks easy to propagate and security difficult to implement. Consequently, to secure these systems, they need to be built in a systematic and holistic way, where security is an integral part of the development lifecycle and not just an activity after development. These systems present a multitude of implementation details in their component units, so it is fundamental to use abstraction in the analysis and construction of their architecture. In particular, we can apply abstraction through the use of patterns. Pattern-based architectural modeling is a powerful way to describe the system and analyze its security and the other non-functional aspects. Patterns also have the potential to unify the design of their computational, communication, and control aspects. Architectural modeling can be performed through UML diagrams to show the interactions and dependencies between different components and its stakeholders. Also, it can be used to analyze security threats and describe the possible countermeasures to mitigate these threats. An important type of CPS is a maritime container terminal, a facility where cargo containers are transported between ships and land vehicles; for example, trains or trucks, for onward transportation, and vice versa. Every cargo port performs four basic functions: receiving, storing, staging and loading for both, import and export containers. We present here a set of patterns that describe the elements and functions of a cargo port system, and a Reference Architecture (RA) built using these patterns. We analyze and systematically enumerate the possible security threats to a container terminal in a cargo port using activity diagrams derived from selected use cases of the system. We describe these threats using misuse patterns, and from them select security patterns as defenses. The RA provides a framework to determine where to add these security mechanisms to stop or mitigate these threats and build a Security Reference Architecture (SRA) for CPS. An SRA is an abstract architecture describing a conceptual model of security that provides a way to specify security requirements for a wide range of concrete architectures. The analysis and design are given using a cargo port as our example, but the approach can be used in other domains as well. This is the first work we know where patterns and RAs are used to represent cargo ports and analyze their security.

Hemodynamic response was measured in bilateral PFC from 48 participants during a study task, where participants processed brand-name products using various attribute processing types (once using one attribute, twice using the same attribute, and twice using two different attributes), and during a purchase intention test, where participants chose to purchase novel or previously processed brand-name products. Analysis of variance compared differences in hemodynamic response as a function of cortical structure, Type of Processing, and task. Results demonstrated repetition suppression in the left PFC for brand-name products that were previously processed for multiple attributes. Findings suggest processing different attributes of the same brand-name product bias purchase intentions, where participants were more likely to purchase brand-name products processed for multiple attributes.

Show moreThe oncogenic role of many of inflammatory genes in prostate cancer (PCa) remains unexplored despite the increasing association of chronic inflammation with PCa initiation, progression, and therapy resistance. The overarching goal of this project was to identify dysregulated inflammatory genes that correlate with PCa progression and seek to understand their molecular mechanisms and the therapeutic potential of targeting them. To achieve this, we utilized cutting-edge integrative (epi) genomic and transcriptomic techniques to identify and characterize inflammatory genes whose deregulation or (epi) genetic alterations correlate with PCa progression. Weighted Gene Co-expression Network Analysis and other multivariate analysis techniques identified IRAK1 as one of the inflammatory signatures found to be overexpressed in over 80% of prostate adenocarcinoma (PRAD) samples. We also explored the diagnostic and prognostic potential of IRAK1 as a biomarker using Kaplan Meier Survival Analysis and AUROC Analysis. DNA methylation analysis showed that IRAK1 is hypomethylated and found to negatively correlate with its overexpression in PRAD patients. We also found some missense and truncated mutations in some patients and reported a high level of IRAK1 gene amplification in castration-resistant and neuroendocrine PCa patients.

Show moreIn this research, three methods of aerosol generation, and their subsequent propagation, are investigated experimentally. These experiments provided insight into the potential risk aerosol can have pertaining to the spread of infectious disease such as COVID – 19. The first of which investigated an alternative generation route that may exist given the discovery of small numbers of viable viruses in urine and stool samples. Flushing biomatter can lead to the aerosolization of micro-organisms; thus, there is a likelihood that bioaerosols generated in public restrooms may pose a concern for the transmission of COVID-19, especially since these areas are relatively confined, experience heavy foot traffic, and may suffer from inadequate ventilation. The results indicate that the particular designs tested in the study generate a large number of droplets in the size range 0.3 𝜇𝑚 – 3 𝜇𝑚, which can reach heights of at least 1.52 m. This highlights the need for incorporating adequate ventilation in the design and operation of public spaces, which can help prevent aerosol accumulation in high occupancy areas and mitigate the risk of airborne disease transmission. Secondly, experiments were conducted to evaluate the effectiveness of facial coverings at various distances around a simulated cough. These concluded that due to the gaps along the seal of a face mask, aerosols can escape 360° around a coughing individual. In the final portion of the thesis study, an experimental method was developed and conducted to break up a droplet via mechanical excitation. The results of these experiments showed that when a droplet is placed on a vibrating string, the droplet can be broken into many secondary droplets which is analogous to one speaking or singing thus providing insight as to how vocal cords can generate respiratory aerosols.

This study investigated the combination of 3-Bromopyruvate (3-BPA) and the anti-inflammatory molecule SC-514 in reducing MDR in prostate cancer. The compounds were incorporated into a PLGA nanoparticles to increase delivery to target cells. To investigate the effectiveness of SC-514 and/3-BPA, cytoxicity assays including trypan blue dye exclusion, MTT tetrazolium reduction, NBT, LDH release poly caspase detection, cell titer glow assay, and ELISA were utilized. Both immunofluorescence and multidrug resistance efflux assays were utilized to estimate the number of drug resistant cells. SC-514 was encapsulated in PLGA nanoparticles via single-emulsion method. SC-514 nanoparticles were analyzed utilizing Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). Liquid chromatography–mass spectrometry (LC–MS) was used to measure the amount of SC- 514 released from the nanoparticle. Alternative SC-514 drug release quantification methods such as colony forming assay, wound healing assay, and transwell and migration assay were explored.

Show moreSynaptic transmission is a mechanism that makes life possible for many organisms. Damaging this crucial process, such as with a buildup of Reactive Oxygen Species (ROS), is extremely detrimental for the entire organism. Previously, the Dawson-Scully lab has determined that exposure of the Drosophila melanogaster neuromuscular junction (NMJ) to ROS accumulation can result in synaptic failure at a faster rate than saline controls (Caplan et al., 2013). To combat such effects, novel three-dimensional Resveramorph compounds were created to act as a neuroprotective agent against the harmful effects of acute oxidative stress (Bollinger et al., 2019; Sial et al., 2019). With the initial Resveramorph compounds demonstrating neuroprotective effects, additional analysis of other Resveramorph compounds were of interest to better understand their role in neuroprotection. Further testing of these compounds allows for the investigation of how chemical structure affects a compound’s neuroprotective activity.

Title: OF RACE AND RESISTANCE: INSIDE AND OUT OF ETHNIC LIVES IN MODERN LITERATURE OF THE AMERICAS.
Creator: Martin, Dyanne K., Esquilín Gosser, Mary Ann, Florida Atlantic University, Department of Languages, Linguistics and Comparative Literature, Dorothy F. Schmidt College of Arts and Letters
Abstract/Description: Race is a pressing issue that pervades discussions of public policy and societal matters in twenty-first century national cultures—even as those populations, paradoxically, turn toward increasing globalization. We need to understand now, more than ever, what race means to us and how and why it means in order for us to understand our deep investments in it. This study explores—through the genres of slave narrative, fiction, and memoir—the process of socio-semiogenesis by which people recognize...
Show moreRace is a pressing issue that pervades discussions of public policy and societal matters in twenty-first century national cultures—even as those populations, paradoxically, turn toward increasing globalization. We need to understand now, more than ever, what race means to us and how and why it means in order for us to understand our deep investments in it. This study explores—through the genres of slave narrative, fiction, and memoir—the process of socio-semiogenesis by which people recognize and perform race; it also examines the customs that allow people not only to form themselves in groups but also to disrupt, remediate, and invert the implicit racial codes that govern human interaction within and among such groups. This study offers a Peircean, triadic approach to the dialectics of race—an approach that seeks to find a space in which dialogue and healing might occur even as it sheds light on those shades of biology and culture that both form and divide us.

Title: PATH PLANNING ALGORITHMS FOR UNMANNED AIRCRAFT SYSTEMS WITH A SPACE-TIME GRAPH.
Creator: Steinberg, Andrew, Cardei, Mihaela, Cardei, Ionut, Florida Atlantic University, Department of Computer and Electrical Engineering and Computer Science, College of Engineering and Computer Science
Abstract/Description: Unmanned Aircraft Systems (UAS) have grown in popularity due to their widespread potential applications, including efficient package delivery, monitoring, surveillance, search and rescue operations, agricultural uses, along with many others. As UAS become more integrated into our society and airspace, it is anticipated that the development and maintenance of a path planning collision-free system will become imperative, as the safety and efficiency of the airspace represents a priority.

Show moreUnmanned Aircraft Systems (UAS) have grown in popularity due to their widespread potential applications, including efficient package delivery, monitoring, surveillance, search and rescue operations, agricultural uses, along with many others. As UAS become more integrated into our society and airspace, it is anticipated that the development and maintenance of a path planning collision-free system will become imperative, as the safety and efficiency of the airspace represents a priority. The dissertation defines this problem as the UAS Collision-free Path Planning Problem. The overall objective of the dissertation is to design an on-demand, efficient and scalable aerial highway path planning system for UAS. The dissertation explores two solutions to this problem. The first solution proposes a space-time algorithm that searches for shortest paths in a space-time graph. The solution maps the aerial traffic map to a space-time graph that is discretized on the inter-vehicle safety distance. This helps compute safe trajectories by design. The mechanism uses space-time edge pruning to maintain the dynamic availability of edges as vehicles move on a trajectory. Pruning edges is critical to protect active UAS from collisions and safety hazards. The dissertation compares the solution with another related work to evaluate improvements in delay, run time scalability, and admission success while observing up to 9000 flight requests in the network. The second solution to the path planning problem uses a batch planning algorithm. This is a new mechanism that processes a batch of flight requests with prioritization on the current slack time. This approach aims to improve the planning success ratio. The batch planning algorithm is compared with the space-time algorithm to ascertain improvements in admission ratio, delay ratio, and running time, in scenarios with up to 10000 flight requests.
