Show moreThe goal of this dissertation was to examine the fate and fragmentation of plastic debris in the marine environment and characterize the microbial communities colonizing naturally occurring substrates and geologically recent plastic inputs in the ocean using analytical chemistry and genomic techniques. Altogether, the data presented herein reveal the presence of heretofore undescribed plastic accumulation zones in the ocean and depict a stark contrast in microbial traits between early and mature plastic biofilm stages. These data further suggest that emergent plastic biofilm properties can be forecasted across environmental gradients, with the largescale genomic characteristics of early colonizers varying little across conditions. Chapter I of this thesis is an introduction to the current body of work regarding the plastisphere. Chapter II explores the ‘cradle to grave’ fragmentation, transformation, and transport of model microplastic particles and single-use plastic items in an artificial beach setting. Chapter III presents the first metagenomic insights into early biofilm formation on virgin microplastic surfaces in the marine environment and how early colonizers self-assemble, compared to mature, taxonomically, and metabolically diverse biofilms residing on free-drifting plastic pollution. Chapter IV further investigates microbial adaptations for initial colonization of virgin control and plastic surfaces and examines biofilm assemblage dynamics by employing metagenomics on a 16-day time series in a wastewater treatment facility. Chapter V synthesizes observations from the previous core chapters and discusses what these findings mean in a broader ecological and evolutionary perspective. Appendix 1 is a reprint of the manuscript describing the distribution of microplastics beneath the inner and outer plastic accumulation zones of the South Atlantic Subtropical Gyre. Appendix 2 is a submitted manuscript detailing the isolation, characterization, and selective adaptations of Vibrio bacteria colonizing eel leptocephali, free-drifting plastic pollution, Sargassum, and seawater in the North Atlantic Ocean.

Learning to read is a fundamental skill that is understudied among children who hear more than one language at home. A particular limitation in the extant literature is that the samples are often Spanish-dominant and come from low-income households. This literature has evidence that Spanish skills – both language-specific (i.e., vocabulary) and language-general (i.e., phonological processing) – predict English reading ability.

Show moreLearning to read is a fundamental skill that is understudied among children who hear more than one language at home. A particular limitation in the extant literature is that the samples are often Spanish-dominant and come from low-income households. This literature has evidence that Spanish skills – both language-specific (i.e., vocabulary) and language-general (i.e., phonological processing) – predict English reading ability. In the current study, we investigated the effect of oral language skills in both English and Spanish, as well as other pre-literacy skills, on the English reading skill of Spanish-English bilinguals who are English dominant and received English only instruction from school entry. The oral language skills and other pre-literacy skills of 101 Spanish-English dual language learners were assessed at 5 years. English reading skill was measured annually from 6 to 10 years. Latent growth curve analysis was used to model initial English reading skill at 6 years and the growth of English reading skill from 6 to 10 years. Four sets of hypothesized foundational skills measured at child age 5 years were tested as predictors of subsequent English reading skill: (1) English oral language skills, (2) Spanish oral language skills, (3) English and Spanish oral language skills, and (4) English and Spanish oral language skills, with other pre-literacy skills. The results of structural equation modeling indicated that English vocabulary and phonological awareness measured in Spanish were significant predictors when English and Spanish skills were entered separately. When English and Spanish oral language skills were included together, Spanish oral language skills did not explain English reading growth better than when oral language skills were modeled independently. The best model of predictors of English reading for bilingual 5-year-olds included only English vocabulary and English letter recognition.

Show moreDespite the historical norm that businesses should refrain from making public political statements for fear of losing customers, recent history has shown an increase in firms wading into controversial sociopolitical topics. As politics become increasingly pervasive in everyday life, consumers, investors, employees, and the general public expect firms to engage in political topics and make their positions clear. However, the considerations and processes firms undertake in deciding whether to take political stands are largely unstudied. This study examines the role of firm executives’ ideologies on their propensity to engage in corporate sociopolitical activism (CSA). Further, I examine how the ideologies of organizational, social, and capital market stakeholders also influence the decision to engage in CSA as executives weigh the desires and expectations of key stakeholders. Using stakeholder theory, I argue that CEOs and top management teams (TMTs) are responsive to the ideological leanings of multiple stakeholder groups, while also considering their own political opinions. Studying a random sample of 139 public firms, I find that CEO and TMT ideologies, on their own, are not reliable predictors of firm CSA. Firms are more likely to engage in CSA when the CEO’s ideology is aligned with that of employees or the region surrounding the firm headquarters. I also find that the volatility of the firm’s stock price reduces the propensity toward CSA, suggesting that the potential for adverse impacts on firm value can blunt firms’ CSA efforts. Further, I find that firm factors, such as B2B vs B2C markets, firm size, and firm reputation also predict the likelihood of CSA. The results have theoretical implications by adding to the nascent body of CSA literature, as well as managerial implications for perceptions of the business environment and political influences.

Show morePrior studies examine either CEO, CFO, or audit committee member gender as a determinant of audit quality. In contrast, this study makes the unique contribution of examining the interactive effects between a gender diverse CEO-CFO dyad and a gender diverse audit committee on audit quality. Further, prior studies examine the attribute of gender as a determinant of audit quality in isolation. I examine the effect of gender on audit quality in tandem with the potentially moderating effect of managerial overconfidence. In doing so, this study makes the unique contribution of examining whether the socialized construct of gender, or the cognitive bias of overconfidence, will weigh more heavily on decisions that relate to audit quality. Results supplement social role and role congruity theories which suggest female leaders are socialized to adopt a management style resulting in more transparent financial reporting and higher audit quality. Specifically, I find incrementally higher audit quality associated with a gender diverse CEO-CFO dyad and audit committee. Further, I find firms with overconfident female CFOs are associated with higher audit quality than firms with overconfident male CFOs. This implies the pressure to maintain the socialized gender role appears to constrain the female manager’s overconfident tendencies. Finally, in a subsample of overconfident CFOs, I find gender diverse audit committees temper female more than male overconfidence for effects on audit quality.

Show moreThis multiple case study explored the lived experiences of LGBTQ educators while they navigated the ongoing disclosure of their sexual orientation and inclusion of LGBTQ curriculum in K-12 public schools. Two main research questions and four sub-research questions guided this study. An electronic questionnaire was used to collect initial information and recruit participants for two rounds of semi structured interviews. The sample population for this study consisted of 8 participants. All eight participants completed the initial questionnaire and the first round of interviews. The first interview focused on the educator’s disclosure and school climate. From the original eight participants, six completed the second round of interviews which focused on inclusive curriculum. Data analysis supported themes and findings which emerged from the coding and are presented according to the research question they address. Research Question 1 found negative and positive experiences LGBTQ educators encountered that are presented according to shareholder groups: (a) administrators, staff, and community, and (b) students. Sub-Research Question 1 had three themes related to the influences school climate had on LGBTQ educators’, and Sub-Research Question 2 findings included the negative, positive, and neutral factors that influence an LGBTQ educator’s disclosure decision. Research Question 2 depicted LGBTQ educators’ experiences with LGBTQ inclusive curriculum. Sub-Research Question 3 identified two themes relating to LGBTQ educators’ feelings toward inclusion. Finally, Sub-Research Question 4 found three shareholder groups: (a) students, (b) school and district, and (c) society. Each group comprised factors that impacted the inclusion of LGBTQ curriculum including (a) barriers, (b) benefits, and (c) support.

Show moreThe Florida Everglades is a vast subtropical wetland that historically spanned over 1,000,000 hectares, but much of the Everglades has changed in the last 100 years due to anthropogenic activity. Collier County was subject to alteration in the form of logging, road building, and canal digging. These actions disrupted the natural sheet flow of water and had large environmental impacts on the region, impacts which are slowly being addressed by Everglades restoration efforts. The aim of this project was to observe the effects of environmental change at a cypress swamp forest in Collier County within the Big Cypress National Preserve. Using sediment core data including charcoal analysis, loss on ignition, and peat humification, as well as remote sensing techniques, this project uses a novel approach to assess local environmental conditions in the modern era. Historical records and contemporary data are used to evaluate change over time, and satellite imagery is used to quantify vegetative health. Modification of the environment related to anthropogenic activity is noted, and evidence of progress from restoration efforts is observed from the last two decades in our study’s data.

Show moreDental school is a four-year, rigorous educational endeavor packed with difficulties and challenges predental students have not experienced during their undergraduate studies. In addition, dental schools demand developing new coping and learning skills to meet the requirements of a student-centered, fast-paced curriculum. In response to these challenges, it is essential to understand and embrace self-directed learning (SDL) skills and attitudes required for predental students to thrive and succeed during their dental journey (Premkumar et al., 2014). Furthermore, SDL is essential in assisting dental students in filtering the information they need to fulfill their learning needs (Siddiqui et al., 2021). This quantitative cross-sectional descriptive study used an online survey designed by QualtricsXM to evaluate self-directed learning readiness (SDLR) level among predental students at Florida Atlantic University (FAU) and whether their SDLR level would differ based on age, sex, race/ethnicity, college/major, and year of study. A convenience sample of 155 FAU predental students completed Fisher et al.’s (2001) 40-item Self-Directed Learning Readiness Scale for Nursing Education (SDLRSNE) and seven demographic questions. Descriptive and inferential statistics were conducted to analyze and answer the six research questions and corresponding hypotheses. The results showed a positive attitude of FAU predental students toward SDL as total SDLR scores ranged from 119 to 179, with a mean of 151.33. Moreover, there was a statistically significant difference in SDLR level among participants based on age, race, and year of study. Contrastingly, there was no statistically significant difference in SDLR level among participants based on sex, ethnicity, and academic major. The college variable was not investigated as all participants were enrolled in the Charles E. Schmidt College of Science.

Show moreThe three novels of Henry James’s “major phase” have alienated many readers in James’s own time and today. I draw on the philosophical school of phenomenology, in particular the work of Maurice Merleau-Ponty and a recent extension by the philosopher Richard Kearney, to suggest that a lack of self-touch by characters in these novels has contributed in a significant but previously unnoticed way to many readers’ sense that these novels feel frustratingly intangible. I make a comparison to the instances of self-touch in other Edwardian novels to underline the difference. I suggest that James is putting forward a model of “middle-distance intimacy” in which intimates orbit each other at a fixed distance, neither coming closer nor moving further away. This kind of intimacy, for James, privileges the eye that sees from across the room over the hand that touches from up close. While this model of intimacy perplexed many readers in James’s time and later, it is a valuable exploration of a different yet—for some—no less satisfactory kind of emotional life.

Self-Gardening seeks to explore the oftentime selfish rationale behind seemingly selfless decisions. In dissecting my motivation, I found insecurity. I don't garden for the joy of it, I garden to feel valuable. Beneath my desire for children, lives the terrifying hesitation of putting more bad into the world. While this thesis does look to shine a light on uncomfortability and insecurity, it has no interest in poking or prodding them. Acknowledgement and awareness are enough.

Transgender identity and the concept of artificial intelligence are constructed and understood through dichotomies such as natural/unnatural and real/artificial, with each dichotomy informing the other; what is “unnatural” is often deemed to be a mimicry of the “natural,” therefore a false representation of what is “real.” By surveying various classic SF texts and their portrayal of AI characters through the lens of transgender studies—drawing upon scholars including Susan Stryker, Sandy...
Show moreTransgender identity and the concept of artificial intelligence are constructed and understood through dichotomies such as natural/unnatural and real/artificial, with each dichotomy informing the other; what is “unnatural” is often deemed to be a mimicry of the “natural,” therefore a false representation of what is “real.” By surveying various classic SF texts and their portrayal of AI characters through the lens of transgender studies—drawing upon scholars including Susan Stryker, Sandy Stone, and Florence Ashley—I assert that artificiality itself is a construction formed by cisnormative ideals and standards to exclude certain others (namely, transgender people) that requires reframing. I examine how these representations in works such as Richard Powers’s Galatea 2.2 reveal and articulate the constructed dichotomies and cultural narratives which surround transgender identity, as well as how contemporary, trans-authored works such as Annalee Newitz’s Autonomous can offer tools for responding to and reconfiguring those dichotomies.

Show moreSea level rise threatens loggerhead sea turtle (Caretta caretta) nests laid close to the high tide line (HTL) with inundation from washover. Boca Raton, Florida is a relatively steep, dynamic beach with changes in beach morphology even during nonactive hurricane seasons. One potential solution to conserve sea turtle nests is to relocate nests laid at or below the HTL closer to the dune. In this study, I examined reproductive success for in situ vs relocated nests. Relocation did not decrease reproductive success, while nests left near the HTL were at risk of washout. During a dry season, nests that experienced one to three days of washover had significantly higher reproductive success than nests that experienced no washover. Relocation can be a useful method to preserve nests against sea level rise, but nonrelocated nests near the HTL may sometimes benefit from washover to cool the nests during hot and dry years.

We sought to determine if Serine 81, within the minimal essential region (MER) of the BNIP3L protein, is required for organelle elimination. Previous studies have shown that levels of phosphorylated P38 MAPK and ERK ½ peaked in the same region as phosphorylated S81 BNIP3L levels, the equatorial epithelium, where organelle degradation is initiated. The use of specific inhibitors of P38 MAPK (SB203580) or ERK ½ (U0126 or PD99089) and P38 MAPK activator Ansiomycin will be used to determine if P38 MAPK or ERK ½ phosphorylates BNIP3L at S81 to induce mitophagy of mitochondria, endoplasmic reticulum, and Golgi apparatus.

The results indicated that formant frequencies were indeed modulated by speaking style, with vowel spaces showing centralization during spontaneous speech compared to read speech. LTFD showed an increase in frequency during spontaneous speech over read speech, particularly in the third long-term formant (LTF3). Sex and age were both significant factors for both vowel space and LTFD, with males and older speakers producing lower frequencies. The examination of the effect of speech style, sex and age on vowel space and LTFD allows us to better understand the factors that play a role in speech production.

Show moreThe world is ever-changing with technological advancement. National economies and private organizations are shifting their infrastructure to adapt to innovation and technology. We are seeing a major shift in our transportation ecosystem as well. Automotive manufacturers are launching fully electric semi-truck (EST) on the road for freight transportation. Electric trucks will have a long-term effect on many industries and the national economy in the United States. Compared to conventional automobiles, the limited range of electric vehicles is a major obstacle. To adapt electric vehicles (EVs) to our transportation system, the U.S. needs a proper charging infrastructure in our grid. Though we have been adapting the passenger EVs, the EST needs larger charging infrastructure capabilities to charge the large batteries of these trucks to complete the journey. The most important aspect is the geographical locations of these mega charging stations along U.S. highways. To analyze the optimal locations of these charging infrastructures, we use the framework from Csiszár et al. (2020), an origin-destination (O-D) data model. OD is classified as the original location of the freight to the end destination. We also use the flow-refueling location model (FRLM) from He et al. (2019). This framework showcases the optimal locations in each route in order to complete the OD pairs. We use data from the U.S. department of energy for the locations of charging stations. Furthermore, we use U.S. department of transportation highway & transportation data to procure the major O-Ds of freight transportation.

The body of research published regarding women’s experiences with SV on college campuses disproportionately focuses on Caucasian women (Oney, 2018). Few studies address the specific concerns of minority women and their experiences with SV and even fewer studies serve to identify contributing factors to their recovery. In addition to the prevalence of SV on college...
Show moreSexual violence (SV) is a significant problem that impacts women on college campuses at an alarming rate (Fischer et al., 2018). The body of research published regarding women’s experiences with SV on college campuses disproportionately focuses on Caucasian women (Oney, 2018). Few studies address the specific concerns of minority women and their experiences with SV and even fewer studies serve to identify contributing factors to their recovery. In addition to the prevalence of SV on college campuses, the rates of rape myth acceptance (RMA) that have been studied among this age group focus primarily on White cisgender men and women, and again, are understudied in women who identify as racial/ethnic minorities (Oney, 2018). Research correlates high levels of RMA with a decreased willingness to accept recovery-promoting assistance post-SV, which reduces a survivor’s willingness to access to services such as counseling (Oney, 2018). The objective of this study was to determine if rape myth acceptance predicts recovery self-efficacy and if experiences of SV serve as a mediating variable between recovery-self efficacy and RMA in ethnic and racial minority college-age women. The results of this study indicate that RMA does not predict or mediate the variables of recovery self-efficacy and SV. A linear regression analysis was used to establish if RMA predicts recovery self-efficacy, the factors within the scales were not correlated and additional tests yielded non-statistically significant results; (b = -0.02, t = -0.29, p = .77). The study also was unable to provide evidence of experiences of SV being a mediating variable between RMA and recovery self-efficacy through a mediation analysis (b =.00, SE = .002, 95% CI = [-.004, .004], p =.89).

The Miami Circle (8DA12) is a site in downtown Miami, Florida with a unique prehistoric feature. The feature is made up of small post holes which reflect a larger patterned arrangement that resembles a circle, most probably the remnants of a prehistoric structure. The Miami Circle was listed on the National Register of Historic Places in 2002 and declared a National Historic Landmark on January 16, 2009. The site has been linked to the Tequesta Indians.

The Miami Circle was listed on the National Register of Historic Places in 2002 and declared a National Historic Landmark on January 16, 2009. The site has been linked to the Tequesta Indians. This project utilized chi-square 𝑥2 test of independence statistical analytical methods using data obtained from the Miami Circle site and neighboring sites to determine the logical boundaries of the prehistoric village called Tequesta. Chi-square testing will determine if there is a statistically significant difference between the sites based on calculations of expected and observed frequency for sets of recovered artifacts.

Show moreIn The Bahamas, the Princess Margaret Hospital is one of the main public facilities used to deliver babies. The hospital is divided into two maternity wards, public and private. This thesis aims to analyze the narratives of mothers’ experiences who have given birth in the hospital. Also, this thesis examines the difference in treatment between mothers’ first, second and third births. The data suggest that the way mothers were treated is based on their age and relationship status during delivery. Notably, mothers on the private ward had the advantage of a family member to witness the delivery pre-COVID, while mothers on the public ward did not experience this privilege. Mothers’ first, second and third birth experiences showed differences based on their increased knowledge of delivery. However, both wards were associated with common issues related to hospital resources, doctor-patient relationships, communication, and perceptions of treatment.

Working memory (WM) enables the flexible representation of information over short intervals. It is established that WM performance can be enhanced by a retrospective cue presented during storage, yet the neural mechanisms responsible for this benefit are unclear. Here, we tested several explanations for retrospective cue benefits by quantifying changes in spatial WM representations reconstructed from alpha-band (8 - 12 Hz) EEG activity recorded from human participants before and after the...
Show moreWorking memory (WM) enables the flexible representation of information over short intervals. It is established that WM performance can be enhanced by a retrospective cue presented during storage, yet the neural mechanisms responsible for this benefit are unclear. Here, we tested several explanations for retrospective cue benefits by quantifying changes in spatial WM representations reconstructed from alpha-band (8 - 12 Hz) EEG activity recorded from human participants before and after the presentation of a retrospective cue. This allowed us to track cue-related changes in WM representations with high temporal resolution. Our findings suggest that retrospective cues engage several different mechanisms such as recovery of information previously decreased to baseline after being cued as relevant and protecting the cued item from temporal decay to mitigate information loss during WM storage. Our EEG findings suggest that participants can supplement active memory traces with information from other memory stores. We next sought to better understand these additional store(s) by asking whether they are subject to the same temporal degradation seen in active memory representations during storage. We observed a significant increase in the quality of location representations following a retrocue, but the magnitude of this benefit was linearly and inversely related to the timing of the retrocue such that later cues yielded smaller increases.
