Restoring Balance, Daniel R. Villanueva Toby

be Still

As a medical student who has received half of their education during the COVID-19 pandemic, I wanted to portray the internal struggle of medical providers in trying to care for the sick and disabled. A great deal is expected of doctors in this day and age. That stress of expectations versus the innate desire to help others led me to write this poem.

Applying Heidegger To Case Study Research In The Medical And Social Sciences, Patrick Whitehead

The Qualitative Report

In this article, I introduce an approach to the case-study method which is based on the work of German philosopher Martin Heidegger (1889-1976). Heidegger’s insights have been applied by philosophers and scholars to the social and health sciences, and this application has increased noticeably over the last decade. This article has been written so that non philosophers may benefit from Heidegger’s insights and apply them to their own research and practice. I begin with a description and overview of the shift in perspective that Heidegger has advocated, and how this shift has turned upside down the fields to which it …

Using Ecological Diversity Analyses To Characterize The Availability Of Healthy Food And Socio-Economic Food Deserts, Annie Goyanes, J. Matthew Hoch

Marine & Environmental Sciences Faculty Articles

“Food deserts” are usually defined as geographic areas without local access to fresh, healthy food. We used community ecology statistics in supermarkets to quantify the availability of healthy food and to potentially identify food deserts as areas without a diverse selection of food, rather than a binary as to whether fresh food is present or not. We test whether produce diversity is correlated with neighborhood income or demographics. Abundance and diversity of fresh produce was quantified in supermarkets in Broward County, Florida, USA. Neighborhood income level and racial/ethnic makeup were retrieved from the U.S. Census and American Community Survey. Although …

Marine & Environmental Sciences Faculty Articles

Background

The growing interest in mineral resources of the deep sea, such as seafloor massive sulphide deposits, has led to an increasing number of exploration licences issued by the International Seabed Authority. In the Indian Ocean, four licence areas exist, resulting in an increasing number of new hydrothermal vent fields and the discovery of new species. Most studies focus on active venting areas including their ecology, but the non-vent megafauna of the Central Indian Ridge and South East Indian Ridge remains poorly known.

In the framework of the Indian Ocean Exploration project in the German license area for seafloor massive …

Periodically Disturbing The Spatial Structure Of Biofilms Can Affect The Production Of An Essential Virulence Factor In Pseudomonas Aeruginosa, Rebecca J. Quinn, Ivana Barraza, Laura García-Diéguez, Camryn Pajon, Lauren E. Krausfeldt, Kerollos Ibrahim, Laura A. Enzinna, Morgan E. Thorn, Omar Tonsi Eldakar, Travis J. A. Craddock, Robert P. Smith

Biology Faculty Articles

Understanding the environmental factors that affect the production of virulence factors has major implications in evolution and medicine. While spatial structure is important in virulence factor production, observations of this relationship have occurred in undisturbed or continuously disturbed environments. However, natural environments are subject to periodic fluctuations, including changes in physical forces, which could alter the spatial structure of bacterial populations and impact virulence factor production. Using Pseudomonas aeruginosa PA14, we periodically applied a physical force to biofilms and examined production of pyoverdine. Intermediate frequencies of disturbance reduced the amount of pyoverdine produced compared to undisturbed or frequently disturbed conditions. …

Metabolomics Of Healthy And Stony Coral Tissue Loss Disease Affected Montastraea Cavernosa Corals, Jessica M. Deutsch, Olakunle A. Jaiyesimi, Kelly A. Pitts, Jay Houk, Blake Ushijima, Brian K. Walker, Valerie J. Paul, Neha Garg

Marine & Environmental Sciences Faculty Articles

Stony coral tissue loss disease, first observed in Florida in 2014, has now spread along the entire Florida Reef Tract and on reefs in many Caribbean countries. The disease affects a variety of coral species with differential outcomes, and in many instances results in whole-colony mortality. We employed untargeted metabolomic profiling of Montastraea cavernosa corals affected by stony coral tissue loss disease to identify metabolic markers of disease. Herein, extracts from apparently healthy, diseased, and recovered Montastraea cavernosa collected at a reef site near Ft. Lauderdale, Florida were subjected to liquid-chromatography mass spectrometry-based metabolomics. Unsupervised principal component analysis reveals wide …

Marine & Environmental Sciences Faculty Articles

Over the past decade, the scientific community has studied, experimented, and published a notable body of literature on ecological enhancement of coastal and marine infrastructure (CMI). The Nature-Inclusive Design (NID) approach refers to methods and technologies that can be integrated into the design and construction of CMI to create suitable habitat for native species (or communities) whose natural habitat has been degraded or reduced. To examine the compliance of new environmentally sensitive technologies with structural requirements and fiscal restraints, while providing ecosystem and habitat value, this paper presents the findings of a structural-economical-biological analysis of ecologically engineered Articulated Concrete Block …

Stable Isotopes Used To Infer Trophic Position Of Green Turtles (Chelonia Mydas) From Dry Tortugas National Park, Gulf Of Mexico, United States, David C. Roche, Michael S. Cherkiss, Brian J. Smith, Derek A. Burkholder, Kristen M. Hart

Marine & Environmental Sciences Faculty Articles

Evaluating resource use patterns for imperiled species is critical for understanding what supports their populations. Here we established stable isotope (δ¹³C, δ¹⁵N) values for the endangered green sea turtle (Chelonia mydas) population found within the boundaries of Dry Tortugas National Park (DRTO), south Florida, USA. There is little gene flow between turtles sampled at DRTO and in other rookeries in Florida, underscoring the need to study this distinct population. Between 2008 and 2015 we collected multiple sample types (skin [homogenized epidermis/dermis], whole blood, red blood cells, plasma, carapace) from 151 unique green turtles, including …

Metaplasia Of Respiratory And Digestive Tissues In The Eastern Oyster Crassostrea Virginica Associated With The Deepwater Horizon Oil Spill, Deanne Roopnarine, Peter D. Roopnarine, Laurie C. Anderson, Ji Hae Hwang, Swati Patel

Biology Faculty Articles

Metaplasia is a well documented and deleterious effect of crude oil components on bivalved molluscs, including oysters. This reversible transformation of one cell type to another, is a common response to petroleum-product exposure in molluscs. It has been shown experimentally in previous work that eastern oysters (Crassostrea virginica) exposed to petroleum products will exhibit metaplasia of digestive tissues. Here we document for the first time that wild adult oysters inhabiting coastal waters in the northern Gulf of Mexico during and in the aftermath of the Deepwater Horizon oil spill (2010) exhibited metaplasia in both ctenidia and digestive epithelia …

Validation Of A Single Channel Eeg For The Athlete: A Machine Learning Protocol To Accurately Detect Sleep Stages, Kayla Thompson, Kamil Celoch, Frankie Pizzo, Ana I. Fins, Jaime Tartar

Journal for Sports Neuroscience

There is a large and growing movement towards the use of wearable technologies for sleep assessment. This trend is largely due to the desire for comfortable, burden free, and inexpensive technology. In tandem, given the competitive nature of professional athletes enduring high training load, sleep is often jeopardized which can result in adverse outcomes. Wearable devices hold the promise of increasing the ease of monitoring sleep in athletes which can inform health and recovery status, as well as aid performance optimization. However, wearable devices typically lack sufficient validity to assess sleep – and especially sleep stages. To address this concern, …

Are Corals Surviving Or Thriving In Highly Degraded Environments? A Reproductive And Trophic Analysis Of Scleractinian Corals, Morgan Short

All HCAS Student Capstones, Theses, and Dissertations

Amid the worldwide decline of corals, the survival of some corals in high nutrient, turbid environments, is intriguing – are they just surviving or are they thriving? This study aimed to determine how these corals acquire energy and whether that energy is sufficient to produce offspring (i.e., develop viable gametes). The nutritional sources and reproductive capacity of Siderastrea siderea in a shipping port (Port Everglades) were compared to two nearshore reefs in Florida, USA and an ex situ coral nursery. Fertility and estimated polyp fecundity were quantified using histological analysis, and water quality parameters were assessed monthly to evaluate differences …

Mako: NSU Undergraduate Student Journal

Eumaeus atala is an endangered tropical butterfly native to the Caribbean and some parts of Florida, USA. Following population reductions primarily due to habitat loss, E. atala populations are now increasing due to conservation efforts of its cycad host plants, especially Zamia integrifolia (coontie). The purpose of this study was to observe, document, and measure the population of wild E. atala on the Ft. Lauderdale, Florida campus of Nova Southeastern University where landscaping use of host plants supports a natural population of E. atala. Forty-four host plants located in two different sites were observed for 14 weeks. One site …

Exploring The Experience Of Anxiety Among Final Year Students At University: A Thematic Analysis, Catriona Keane, Daniel Waldeck, Andrew Holliman, Simon Goodman, Kubra Choudhry

The Qualitative Report

The transition from undergraduate study to a postgraduate career can be an anxiety provoking experience for many students. In this study, we explore the shared experience of five “anxious” undergraduate students as they transition from higher education towards their postgraduate careers. Using a qualitative methodology, semi-structured interviews were conducted with five female undergraduate students from different courses at a UK university. A thematic analysis revealed two overarching themes: perceived pressure without sufficient support, and concerns about next steps. The findings suggested the final year is emotionally demanding, and students felt as though there was a lack of provision to manage …

Inhibition Of Aminoglycoside 6’-N-Acetyltransferase Type Ib [Aac(6′)-Ib]: Structure-Activity Relationship Of Substituted Pyrrolidine Pentamine Derivatives As Inhibitors, Kenneth Rocha, Jesus Magallon, Craig Reeves, Kimberly Phan, Peter Vu, Crista L. Oakley-Havens, Stella Kwan, Maria S. Ramirez, Travis Lavoi, Haley Donow, Prem Chapagain, Radleigh Santos, Clemencia Pinilla, Marc A. Giulianotti, Marcelo E. Tolmasky

Mathematics Faculty Articles

The aminoglycoside 6′-N-acetyltransferase type Ib [AAC(6′)-Ib] is a common cause of resistance to amikacin and other aminoglycosides in Gram-negatives. Utilization of mixture-based combinatorial libraries and application of the positional scanning strategy identified an inhibitor of AAC(6′)-Ib. This inhibitor’s chemical structure consists of a pyrrolidine pentamine scaffold substituted at four locations (R1, R3, R4, and R5). The substituents are two S-phenyl (R1 and R4), an S-hydroxymethyl (R3), and a 3-phenylbutyl (R5) groups. Another location, R2, does not have a substitution, but it is named because its stereochemistry was modified in some compounds utilized in this study. Structure-activity …

The Qualitative Report

In this autoethnographic article we focus on the issues of “disability” and “inclusive education” and the challenges of being positive and affirming in this area of research and practice. As a teacher, I (Alina) continue to encounter regularly the dominant deficit view of “disability,” in spite of the extensive body of literature that advocates for the rights of people with disabilities as well as the benefits of inclusive education best built on strength-based thinking. The autoethnographic methodology allowed me to explore my experiences as an educator and reflect on specific events, presented through four vignettes that capture how my beliefs …

The Age And Growth Of The Yellow Stingray (Urobatis Jamaicensis) In Southeast Florida, Jessica Schieber

All HCAS Student Capstones, Theses, and Dissertations

The yellow stingray, Urobatis jamaicensis (Cuvier 1816), is a coastal species that has limited known life-history information, especially regarding their age and growth patterns. Age estimates were assigned by counting band-pairs deposited on the vertebral centrum of stingrays caught between 2003 and 2019 (n = 195). Marginal increment analysis of different size classes was used to validate age estimates, with the largest class having verified annual band deposition (ANOVA, F(9,7), P = 0.029). Age estimates ranged between females, and rates, but females attained larger sizes with the largest observed DW being 241-mm and 216-mm for females and males, respectively. …

The Variability Of Seawater Carbonate Chemistry In Two Florida Urban Mangrove Ecosystems, Alexandrina R. Rangel

All HCAS Student Capstones, Theses, and Dissertations

Anthropogenic carbon dioxide (CO₂) emissions into the atmosphere are yielding serious impacts across the world’s ocean, including ocean acidification, sea level rise, and increasing seawater temperature. However, these changes are not occurring uniformly across all marine ecosystems. Coastal ecosystems, such as mangroves, already experience extreme and variable environmental conditions due to natural biogeochemical and physical processes. The goal of this study was to document small-scale variability in two urban mangrove ecosystems to gain insight into how ocean acidification will manifest within these systems. Using a stand-up paddleboard, a suite of sensors, and traditional bottle sampling techniques, we measured …

The Distribution, Composition, And Management Of Drifting Fish Aggregating Devices (Dfads) In The North Atlantic Ocean, Erin E. Kimak

All HCAS Student Capstones, Theses, and Dissertations

Drifting Fish Aggregating Devices (dFADs) are a gear accessory utilized on a global scale by commercial fishers to increase catch size and efficiency of target pelagic fishes such as tuna and dolphinfish. Despite their widespread use, there are few scientific estimates of the total number of abandoned or beached dFADs in the Atlantic Ocean and Caribbean Basin or the compliance of dFAD use with t-RFMO recommendations. Previous studies have utilized the modeled drift trajectories of dFADs to predict beaching probability and location, but this study is the first of its kind, analyzing true beaching events. This study identifies the beaching …

Genetic Population Dynamics Of The Critically Endangered Scalloped Hammerhead Shark (Sphyrna Lewini) In The Eastern Tropical Pacific Ocean, Sydney P. Harned

All HCAS Student Capstones, Theses, and Dissertations

The scalloped hammerhead shark, Sphyrna lewini, is a Critically Endangered, migratory species known for its tendency to form large aggregations of mostly adult females, especially in the heavily-fished Eastern Tropical Pacific (ETP) Ocean. This species forms iconic, visually spectacular, seasonal aggregations in the northern Galápagos Islands, and it is hypothesized based on telemetry studies that pregnant females from these aggregations migrate to mainland coastal nurseries for parturition. This study investigated the population genetic dynamics of the scalloped hammerhead across most of its coastal and offshore distribution (Mexico to Ecuador) in the ETP, focusing on young-of-the-year animals sampled from nursery …
