The Qualitative Report

Urban farming has been transformed into urban agricultural activities oriented towards optimizing economic benefits through export market involvement. However, the expansion of the market has consequences for farmers. The involvement of urban farmers in export trade causes market pressures that affect agricultural production practices. This research used qualitative research methods. There were 27 informants in this study. Researchers collected data to determine market pressures faced by export-scale urban farmers in Bandung Metropolitan. Data collection techniques used in-depth interviews, observation, and documentation. The results showed that the market had put pressure on export-scale urban farmers in Bandung Metropolitan to meet international …

Finding Resilience Through Research: Completing A Ph.D. While Parenting An Intellectually Disabled Adult “Child”, Lorraine M. Hutton

The Qualitative Report

Unlike the progression of most traditional-aged, college or university students, my non-traditional, academic trajectory as a parent-caregiver to an intellectually disabled (ID) adult has been fraught with barriers, disruption, and discouragement. Motivation to complete my doctorate rests on a commitment to disability issues, caregiver activism, and intellectual capacity-building of my self. Guided by the “evocative” autoethnographic methodology of Bochner and Ellis (2016), this “insider’s” narrative retrospective autoethnography will attempt to shed light on and evoke an understanding of a doctoral student caregiver’s context and experience in the academy. It encompasses embodiment, a geographically constrained sense of place, marginalization, and neoliberal …

The scale of the Deepwater Horizon disaster was and is unprecedented: geographic extent, pollutant amount, countermeasure scope, and of most relevance to this Research Topic issue, range of ecotypes affected. These ecotypes include coastal/nearshore, continental shelf, deep benthic, and open-ocean domains, the last of which is the subject of this synthesis. The open-ocean ecotype comprises ~90% of the volume of the Gulf of Mexico. The exact percentage of this ecotype contaminated with toxins is unknown due to its three-dimensional nature and dynamics, but estimates suggest that the footprint encompassed most of its eastern half. Further, interactions between the water column …

The Deep-Pelagic Sergestid Shrimp Assemblage In The Gulf Of Mexico In The Vicinity Of The Deepwater Horizon Oil Spill, Erik W. Hine

All HCAS Student Capstones, Theses, and Dissertations

This thesis focuses on the geographical (near-slope vs. offshore) and temporal analyses (2011 – 2018) of the Sergestidae assemblage, the crustacean family with the fourth highest total biomass, in the Gulf of Mexico near the location of the Deepwater Horizon oil spill. The abundance and biomass of the assemblage were analyzed to determine if statistical differences were present between the near-slope and offshore environments. In addition, this study analyzed the vertical distributions of sergestid species in the epipelagic, mesopelagic, and bathypelagic zones to determine the extent of the migratory behavior of these species. Lastly, the abundance and biomass in the …

The Microbiome Characterization And Comparison Of Loggerhead (Caretta Caretta) And Green (Chelonia Mydas) Sea Turtle Eggs In Broward County, Florida, Colleen Mcmaken

All HCAS Student Capstones, Theses, and Dissertations

All seven extant species of sea turtles are classified as threatened or endangered due to natural and anthropogenic impacts. Sea turtle conservation efforts are largely dedicated to ensuring healthy nesting activity. Hatching success of sea turtle eggs can be affected by several factors including the proliferation of pathogenic microbes. However, it is unclear as to which microbes have the most impact on hatching success and how they are transmitted into the eggs. The primary aims of this study characterized and compared the bacterial communities (microbiomes) from the i) cloaca of nesting sea turtles; ii) sand within and surrounding the nests …

Periodic Spatial Disturbances Alter The Expression Of Quorum Sensing Virulence Factors In Pseudomonas Aeruginosa, Laura García-Diéguez

All HCAS Student Capstones, Theses, and Dissertations

Pseudomonas aeruginosa is an opportunistic pathogen associated with severe acute and chronic illnesses. Current antibiotic-based approaches fail to effectively treat P. aeruginosa infections due to the effectiveness and robustness of the quorum sensing signaling system (QS). Pathogenic bacteria, such as P. aeruginosa, employ this population density-dependent communication mechanism to confer antimicrobial resistance, propagate infection, and coordinate the expression of virulence factors, through the production and detection of autoinducing signaling molecules (AI). As such, there is a growing interest in developing novel non-antibiotic-based techniques to attenuate the pathogenicity of P. aeruginosa by disrupting the functionality of its QS system. Previous …

Accumulation Of Persistent Organic Pollutants In Marine Mammals: A Case Study On Cetaceans, Pinnipeds, And Sirenians, Alydia Moorhead

All HCAS Student Capstones, Theses, and Dissertations

Persistent organic pollutants (POPs) are lipophilic semi-volatile organic chemicals that present a range of challenges to marine biota, specifically marine mammals that often occupy a high trophic position in the food web. POPs have become a global problem since they have been shown to cause immunologic, teratogenic, carcinogenic, neurological, and reproductive complications in living organisms due to their resistance to biodegradation and their lipophilic nature. Marine mammals can accumulate these toxic substances through direct ingestion, trophic transfer, adsorption, and maternal offloading. They are susceptible to both bioaccumulation and biomagnification of POPs. Accumulation of POPs is affected by many variables, including …

A Spatial Assessment Of Impacts To The Flats Fishery By Recreational Boating In The Florida Keys National Marine Sanctuary, Kristin Anderson

All HCAS Student Capstones, Theses, and Dissertations

The recreational flats fishery in the Florida Keys is a significant component of the marine resource-based economy, exceeding $465 million (USD) in annual economic impact. Permit (Trachinotus falcatus), bonefish (Albula vulpes), and tarpon (Megalops atlanticus) are the three main species targeted by flat fishers. Those participating in this fishery generally practice catch-and-release angling therefore, the fishery is considered a more sustainable marine use compared to more traditional commercial fisheries. However, with population and tourism rising in South Florida, the fishery is increasingly threatened by habitat degradation and user conflicts. Ongoing revisions to the Florida …

Population Genomic Dynamics Of Mesopelagic Lanternfishes Diaphus Dumerilii, Lepidophanes Guentheri, And Ceratoscopelus Warmingii (Family: Myctophidae) In The Gulf Of Mexico, Andrea Bernard, Kimberly A. Finnegan, Tracey Sutton, Ron Eytan, Max Weber, Mahmood Shivji

Marine & Environmental Sciences Faculty Articles

Assessing the impacts of the Deepwater Horizon oil spill (DWHOS) on deep-sea fish assemblages of the Gulf of Mexico (GOM) has been hindered by an absence of baseline (pre-spill) data concerning the population genetic dynamics of these fishes. The lanternfishes (Myctophidae) are a speciose, yet understudied, taxonomic group, that comprise a significant portion of the global deep-sea biomass, making them integral members of meso- and bathy-pelagic food webs. Herein, we used a genomic approach (double digest restriction site associated DNA sequencing) to investigate the temporal genetic dynamics of three species of lanternfishes within the northern GOM in the region of …

Assemblage Composition And Vertical Distributions Of Deep-Sea Anglerfishes (Suborder: Ceratioidei) Of The Northern Gulf Of Mexico, Kimberly S. Schmutz

All HCAS Student Capstones, Theses, and Dissertations

The bathypelagic zone, despite being the largest cumulative ecosystem on the planet, represents the largest data gap in biological oceanography. In a deep environment with no solar light and pressures so high that survival is impossible for most marine organisms, some species have been able to adapt and overcome these challenges to radiate into diverse and successful taxa. Among the most notable of these successful taxa are the deep-sea anglerfishes (Lophiiformes: Ceratioidei). Ceratioid anglerfishes possess unique adaptations such as a symbiotic bioluminescent lure (females) and extreme dwarfism (males) that make them a particularly interesting group to study. Despite this research …

Trophic Ecology Of A Dominant Mesopredatory Fish Family (Alepisauridae) In The Western North Atlantic Revealed By Stomach Content And Stable Isotope Analysis, Ellyn Willse

All HCAS Student Capstones, Theses, and Dissertations

The mesopelagic zone of the ocean is gaining increased notice due to its potential for commercial value and the lack of knowledge of its ecosystems. Lancetfishes, Alepisaurus spp., are large mesopelagic predators and common bycatch species in commercial fishing operations that potentially play a role in connecting epipelagic and mesopelagic waters and may be a source of carbon from near the surface to the mesopelagic. While little is known about the behavior and biology of Lancetfishes, they share many food sources, and are themselves a food source for important commercial fisheries species such as tuna and swordfish. This study examines …

Impact Of Interleukin-34 On The Promotion Of Bone Osteolysis And Neuroinflammation In Experimental Models Of Alzheimer’S Disease, Anny Ho

All HCAS Student Capstones, Theses, and Dissertations

Alzheimer’s disease (AD) is a growing health concern and is the most common type of dementia worldwide. Emerging evidence indicates that aggregated amyloid-beta (Aβ) peptides, one of the hallmark features of AD neuropathology, can increase RANKL-mediated osteoclast activity leading to the prevalence and severity of inflammatory osteolysis, e.g., osteoporosis and periodontal bone loss. Conversely, osteolytic lesions are associated with increased risk of dementia diagnosis indicating that there is a direct link between dementia and inflammatory osteolysis. It was demonstrated that the neuronal cells primarily produce interleukin-34 (IL-34) and microglia, macrophages, and osteoclast precursors express colony-stimulating factor 1 receptor (CSF-1R), a …

Marine & Environmental Sciences Faculty Articles

Species-specific hematological reference values are essential for diagnosis and treatment of disease and maintaining overall health of animals. This information is lacking for many species of elasmobranchs maintained in zoos and aquaria, thus reducing the effectiveness of care for these animals. Descriptive statistics and reference intervals were calculated for hematocrit and complete blood cell counts, biochemistry and protein electrophoresis parameters, trace minerals, vitamins, heavy metals, reproductive hormones, and fatty acids in the blood of 153 wild Sand Tigers Carcharias taurus of both sexes and a range of sizes caught in Delaware Bay (Delaware, USA). Mean hematocrit, total white blood cell …

Modeling And Simulation Of Microscopic Fibers In A Viscous Fluid, William Mitchell

Mathematics Colloquium Series

In biology, the movements of tiny structures often rely on the mechanical properties of long, thin tubes. For example, bacteria swim by rotating their flagella, and in cell division (mitosis) the two copies of the DNA must be pulled apart by microtubules. To understand these processes it is very tempting to take advantage of the large aspect ratio of the thin structures, for example by modeling them as one-dimensional curves rather than as more complicated objects with volume and surface area. This kind of shortcut saves a lot of work! I will describe one standard and widely used tool known …

The Effect Of Fluorinated Substitution Of Meso Phenyl Porphyrins On Porphyrin Basicity, Harsh Chheda, Rushi Patel, Maria Ballester, Victor Castro

Chemistry and Physics Faculty Proceedings, Presentations, Speeches, Lectures

The purpose of this study was to determine the effects of fluorinated substitution of meso phenyl porphyrins on porphyrin basicity. The protonation of meso-Tetra(2,3,4-trifluoromethylphenyl) porphyrin (TF) and meso-Tetra(pentafluorophenyl) porphyrin (PF) will be studied through UV vis spectroscopy. Protonation is achieved by titration of each porphyrin in toluene with trifluoroacetic acid (TFA). The presence of a wavelength shift from the free base Soret to the protonated Soret will indicate the formation of a dication. The data from the UV spectra will be used to calculate the pKa values associated with each porphyrin. Based on the results, the average pKa for TF …

A Computational Analysis Of Structural Analogs Of Colchicineas Potential Microtubule Polymerization Inhibitors, Isadora Rocha De Abreu, Allison Barkdull

Undergraduate Student Symposium

Microtubules are structures important for cell survival and cell function. They are responsible for the formation of the cytoskeleton and mitotic spindles, they aid in cell movement, intracellular transport, amongst other functions. Microtubules are composed of the tubulin protein made of alpha-beta dimer proteins. During polymerization tubulin proteins experience phases of dynamic instability, characterized by microtubule growth and shrinkage at varying rates. Microtubule growth can be inhibited by compounds such as colchicine, a known microtubule destabilizing agent, that binds to tubulin inhibiting microtubule polymerization. Colchicine has limited clinical use due to its toxicity and low solubility. In this study we …

A Mathematical And Ergonomic Analysis Of Fundamental Laparoscopic Surgery Tools And Techniques, Joshua Bennett, Anneleissa Lugay, Daniel Celestino, Paula Veras

Undergraduate Student Symposium

Laparoscopic surgery is a means to perform procedures in a minimally invasive manner. For surgeons, this requires further training due to increased complexity and fatigue. The goal of these experiments was to study the ergonomics of laparoscopic tools and the physical and cognitive requirements of the Fundamentals of Laparoscopic Surgery (FLS) tasks.

Surface electromyography (sEMG) was used to measure muscle fatigue on the left and right trapezius and electroencephalogram (EEG) was used to record brain waves of the participants. The percent maximum voluntary contraction (%MVC) concept was used to measure fatigue levels. Mean power spectral density was used to categorize …

A Novel Tcr Clustering Method For Sars-Cov-2 Epitopes, Naziba Akther Nuha

Undergraduate Student Symposium

T-cell epitopes are peptides generated from antigens that are presented by MHC class I and class II molecules to T-cells. These epitopes are usually identified by T-cell receptors (TCRs) of CD4 T-cells which then causes transformation of CD4 T-cells to helper or regulatory T cells. In this project, we look at the different TCR sequences of the same length that are activated by two different epitopes for the SARS-COV-2. Building on previous work using Principal component analysis to analyze twenty different physiochemical properties of amino acids, we convert the amino acids in the TCR sequences to numerical strings. We then …

A Preliminary Survey Of Dog-In-Prison Programs Across The Us, Isabella Defilippis, Janan Abushaban, Mariya Baig, Ariel Cherry, Naziha Mustafa, Trini Somasundaram, Ashesh Soni

Undergraduate Student Symposium

The molecular effects of canine-human bonding have not been well-studied, but both species are deeply driven to seek out prosocial interactions. We therefore expect to see quantitative changes in both physiological biomarkers (e.g. cell-level phenotypes linked to psychiatric disease) and animal behavior on both sides of the ancient (>15,000 year old) symbiosis between dogs and humans when dogs and people form interspecies dyads. A compelling context for studying this involves "dog-in-prison" programs, in which incarcerated humans help to train canines for future lives as companionship or service animals. Notably, both the incarcerated humans and orphaned/stray dogs within such programs …

An Episodic Study Of Hospital Charges For Hospital Admissions And Readmissions In 2017 In The United States For Degenerative Nerve Systems Disorders (Drg = 056), Esha Sultana

Undergraduate Student Symposium

Understanding hospital charges upon admission as well as readmissions is critical for value-based care. The extant literature focuses on patient-specific, disease-specific, and hospital-specific factors to explain the variance in hospital charges across the United States. Studies have mainly examined hospital charges upon admissions but there has been lack of empirical research on examining hospital charges upon readmissions. This has resulted in ambiguity in understanding the primary determinants of hospital charges upon readmissions. To address this gap, the federal agency AHRQ developed the HCUP hospital readmissions database that produces nationally representative information about hospital readmissions. This study utilizes the AHRQ 2017 …

Bilinguals Demonstrate Stronger Inhibitory Response Bias In Tasks Of Executive Function, Samruddhi Ayachit, Erika Cabrera Ranaldi

Undergraduate Student Symposium

From switching from one task to another or quickly memorizing a number to call, people use executive function daily. Executive function is thought to be controlled by frontal lobe inhibitory processes. Reportedly, people who speak more than one language also use the same frontal lobe processes to switch between languages. It is therefore believed that these inhibitory processes are more prominent in bilinguals because of the experience of controlling multiple languages. To test this theory, bilinguals and monolinguals were compared on executive function tasks. Participants were matched on demographic variables and fluid intelligence. To examine inhibition, participants were tested with …
