Barriers To School-Based Parent Involvement While Living In Public Housing: A Mother’S Perspective, Stephanie Lechuga-Peña, Daniel Brisson

The Qualitative Report

Parent involvement is associated with child academic outcomes, positive behaviors, and social skills. This qualitative study explored school-based parent involvement barriers experienced by nine low-income mothers. In-depth interviews were used to collect data from mothers participating in a community-based program offered in a large public housing neighborhood. Findings included three main barriers: (a) cultural and language differences in their children’s school, (b) undertones of racism from teachers and parents, and (c) being the primary caregiver or sole provider for their children. Although all parents experience challenges to school involvement, low-income mothers face additional obstacles preventing them from engaging in their …

A Temporal Analysis Of A Deep-Pelagic Crustacean Assemblage (Decapoda: Caridea: Oplophoridae And Pandalidae) In The Gulf Of Mexico After The Deepwater Horizon Oil Spill, Devan Nichols

HCNSO Student Theses and Dissertations

In 2010, the largest oil spill in U.S history occurred off the coast of Louisiana from April 20^th to September 19^th, when the well was declared officially sealed by the U.S Coast Guard, after releasing more than 4.4 million barrels of crude oil into the Gulf of Mexico (GOM) (McNutt et al., 2012). This spill was unique because it occurred in deep water approximately 1500 m below the ocean surface. Virtually nothing is known about the effects of oil spills on marine life in the deep sea, and there are limited data on mesopelagic and bathypelagic animals …

Fine Grained Compositional Analysis Of Port Everglades Inlet Microbiome Using High Throughput Dna Sequencing, Lauren M. O'Connell, Song Gao, Donald S. Mccorquodale Jr., Jay M. Fleisher, Jose Lopez

Marine & Environmental Sciences Faculty Articles

Background

Similar to natural rivers, manmade inlets connect inland runoff to the ocean. Port Everglades Inlet (PEI) is a busy cargo and cruise ship port in South Florida, which can act as a source of pollution to surrounding beaches and offshore coral reefs. Understanding the composition and fluctuations of bacterioplankton communities (“microbiomes”) in major port inlets is important due to potential impacts on surrounding environments. We hypothesize seasonal microbial fluctuations, which were profiled by high throughput 16S rRNA amplicon sequencing and analysis.

Surface water samples were collected every week for one year. A total of four samples …

Ecological Correlates Of Community Structure In Seagrass-Associated Fishes In North Biscayne Bay And Port Of Miami, Florida, Elizabeth F. Colhoun

HCNSO Student Theses and Dissertations

Seagrass habitats are critical habitat for many fish species and are currently threatened by anthropogenic and natural factors, such as coastal development, pollution, global climate change, and sea level rise. There are few studies that have tracked long- term changes in seagrass habitat and their associated fish communities. This project addressed this need using data collected by the United States Geological Survey (USGS) from two South Florida sites, North Biscayne Bay, FL (NBB) and Port of Miami, FL (POM). The USGS sampling was part of ongoing monitoring projects designed to assist future management decisions that would enhance the protection of …

Assessment Of Metals In Tissues Of Marine-Associated Birds In South Florida, Caitlyn A. Nay

HCNSO Student Theses and Dissertations

Seabirds – broadly defined as any bird species associated with the marine environment – are exposed to a wide range of environmental contaminants. Vectors of exposure to metal pollution include by external contact, inhalation, and most often ingestion of food and incidental seawater. Seabirds are often considered marine ecosystem bioindicators due to their high trophic position, relatively long lifespan, and wide geographic ranges. We examined the concentration of total mercury (THg), lead (Pb), and cadmium (Cd), in the kidney, liver, breast muscle, and feathers of seven species of juvenile and adult seabirds commonly found in South Florida: brown pelican Pelecanus …

Evaluating The Efficacy Of Using Geomorphology As A Surrogate To Benthic Habitat On The Miami Terrace, Kim D. Smith

HCNSO Student Theses and Dissertations

The deep-sea is a vast and relatively sparsely characterized domain. As little as 0.01% of deep-sea benthic habitats have been characterized in detail. Characterizing the distribution of organisms and environmental components of the deep-sea is pivotal to the creation and implementation of successful resource management. Benthic habitat maps are a good method to inventory and characterize deep-sea habitats. Recent advances in technology, such as multibeam sonar and remotely operated vehicles (ROVs), have allowed for greater understanding of these ecosystems. As it is difficult and expensive to collect data deep-sea benthic community composition, environmental surrogates of biological data would be economically …

Patterns In Caribbean Coral Spawning, Anna C. Jordan

HCNSO Student Theses and Dissertations

Most corals worldwide are broadcast spawners that rely on synchronous gamete release for successful fertilization. Spawning synchrony may also decrease the probability of heterospecific fertilization that may produce maladaptive hybrids. Despite the importance of reproductive timing, researchers have only recently begun to collect spawning data across coral species in the Caribbean, but these data remain to be analyzed. This study investigates interannual, seasonal, and environmental patterns that may influence Caribbean scleractinian spawning times. The number of spawning observations varies widely among location and species. Most spawning observations were collected in Florida, Curaçao, and Flower Garden Banks National Marine Sanctuary. Acropora …

Population Dynamics Of The Threatened Staghorn Coral, Acropora Cervicornis, And The Development Of A Species-Specific Monitoring Protocol, Elizabeth Goergen

HCNSO Student Theses and Dissertations

Historically, Acropora cervicornis was found in high densities on many Caribbean, Florida, and Gulf of Mexico reefs. A disease outbreak in the late 1970s and 80s caused up to 99% loss of A. cervicornis cover at some sites, leaving populations sparsely distributed throughout its range and typically found as isolated colonies. Even though populations are depauperate causing a decrease in sexual reproduction, its fast growth rate and ability to reproduce through asexual fragmentation affords this species the potential for quick recovery and population growth. However, limited to no natural recovery has been documented. Many of these populations are poorly studied …

Genetic Population And Evolutionary Dynamics Of The Angel Sharks, Squatina Spp., Cristin Keelin Fitzpatrick

HCNSO Student Theses and Dissertations

Once so abundant as to be called the ‘common’ angelshark, Squatina squatina has been extirpated from nearly the entirety of its historical range, from the eastern North Atlantic, to the Mediterranean Sea [International Union for the Conservation of Nature (IUCN) Red List: Critically Endangered]. The angelshark now only occurs in any abundance in the waters surrounding the Canary Islands. I present the first genetic assessment of the angelshark’s population dynamics and diversity from three locations within the Canary Islands archipelago: Gran Canaria, Tenerife, and Lanzarote. Using a suite of individual mitochondrial genome regions [Control region (CR), NADH dehydrogenase subunit 2 …

Biological And Abiotic Factors Influencing Cetacean Mass Strandings In The Northeastern United States, Octavia Williams

HCNSO Student Capstones

Marine mammal strandings are frequent occurrences along many coastal areas around the world. The significance of stranded cetaceans has been of interest since around 300 B.C. when philosophers, like Aristotle, pondered why marine mammals, including whales, dolphins and porpoise beach themselves; and famous authors, like Henry David Thoreau, whose fascination in mammal strandings lead him to write a book about these mass occurrences off the coast of Cape Cod. Numerous hypothetical theories have been developed to explain these mass stranding phenomena. Though the causes of mass strandings remain unresolved, recent investigations suggest contributing factors could include environmental elements. Less emphasis …

Trophic Ecology And Parasitism Of A Mesopelagic Fish Assemblage, Matthew Woodstock

HCNSO Student Theses and Dissertations

Mesopelagic (open ocean, 200-1000 m depth) fishes are important consumers of zooplankton and are prey of oceanic predators. Some mesopelagic fishes (e.g., myctophids and stomiids) undertake a diel vertical migration where they ascend to the near-surface waters during the night to feed and descend into the depths during the day to avoid predators. Other mesopelagic fishes (e.g., Sternoptyx spp.) do not vertically migrate and remain at deep depths throughout the day. While in the epipelagic zone (surface – 200 m depth), vertically migrating fishes become prey to upper-trophic level predators, such as: tunas and billfishes. Benthic fishes (e.g., macrourids) often …

Identification And Spatiotemporal Dynamics Of Tuna (Family: Scombridae; Tribe: Thunnini) Early Life Stages In The Oceanic Gulf Of Mexico, Nina Pruzinsky

HCNSO Student Theses and Dissertations

Fishes within the family Scombridae (i.e. tunas, mackerels and bonitos) are of high ecological and economic value, as they are heavily targeted by commercial and recreational fisheries. In coastal and open-ocean environments, adults are high-level predators, while larvae and juveniles serve as prey for numerous species. Much is known about the distribution and abundance of adult tunas, but high taxonomic uncertainty and limited knowledge regarding the distributional patterns of larval and juvenile tunas have led to an “operational taxonomic unit” gap in our understanding of tuna ecology. Scombrids were collected across the Gulf of Mexico (GoM, hereafter) during seven research …

The British Art Of Colonialism In India: Subjugation And Division, Aziz Rahman, Mohsin Ali, Saad Kahn

Peace and Conflict Studies

This article utilizes a three-pronged analytical model to examine the mechanics of British colonialism and its socioeconomic and political consequences in India. Those three elements are divide and rule, colonial education, and British laws. The British took some reformative initiatives that ostensibly deserve appreciation such as the development of a predictable legal system, investment in infrastructure development, and education in the late nineteenth and mid-twentieth centuries. However, most colonial policies and reforms were against the will and welfare of the people of India. The British took away India’s resources and introduced the English educational system to create an educated and …

The British Colonization Of Australia: An Exposé Of The Models, Impacts And Pertinent Questions, Peter Genger

Peace and Conflict Studies

By adopting the purview of Peace and Conflict Studies and the expository approach of historical archaeology of colonialism, this paper succeeds in enumerating the models the British used to establish and perpetuate colonial violence on the Indigenous Australians, and the traumatizing impacts the violence is exerting on them. The sole essence of the paper is not only to re-establish that the British colonization of Australia was deliberate, just as the heinous models they used. Most essentially, the paper identifies the following institutions: Peace and Conflict Studies (PACS), the UN and challenges them to move from their current inert condemnation of …

Teachers’ Perspectives Regarding The Impacts Of The Secondary Education Expansion Policy On Students’ Self-Regulatory Learning Experiences In Tanzania, Godlove Lawrent

The Qualitative Report

Since 2004, the Tanzania secondary education sector has witnessed a significant increase in the number of new schools and enrolment rates. At the same time, academic results have indicated an increase in poor student performance. The assumption has been that the expansion policy brought about devastating consequences for student learning. The purpose of this study, therefore, was to investigate the perceptions of teachers in relation to the impacts of the government’s secondary education expansion policy on students, especially their self-regulatory learning. A qualitative case study approach was employed, and interviews were used as data gathering tools. Thirty respondents were purposively …

The Role Of Ontogenetic Habitat Shifts On The Parasite Communities Of Five South Florida Fishes, Brittany Nicole White

HCNSO Student Theses and Dissertations

Many reef fishes initially recruit into mangroves, and then migrate out to reef habitats as they grow and mature. Each ontogenetic habitat shift exposes migrants to previously unencountered parasite taxa, potentially increasing parasite species richness and driving changes in parasite community structure. However, studies on this topic rarely attempt to distinguish between the location effects of habitat shifts versus a simple increase in physical size. Therefore we contrasted parasite community richness and structure in Great Barracuda Sphyraena barracuda (N=84), Atlantic Needlefish Strongylura marina (N=49), Crevalle Jack Caranx hippos (N=59), White Mullet Mugil curema (N=90), and Yellow-fin Mojarra Gerres cinnerus (N=60) …

Pathogen Transmission Techniques And Genotypic Resistance To Disease In The Threatened Coral, Acropora Cervicornis, Megan Bock

HCNSO Student Theses and Dissertations

Unprecedented population losses of the staghorn coral, Acropora cervicornis, since the 1970s have been attributed primarily to disease. Although a positive linear relationship between disease prevalence and increased water temperature has been described, the pathogen(s) causing disease and whether they are spread through the water or vectors is still poorly understood. Additionally, an increase in disease outbreaks and severity has provided an urgent need to identify natural genotypic resistance to disease in Caribbean acroporids. Studies to date have explored a variety of pathogen transmission methods, but prior to this study, there has been no examination of differences among common techniques. …

Identifying Disease-Resistant And Thermal-Tolerant Genotypes In The Threatened Staghorn Coral, Acropora Cervicornis, Morgan V. Hightshoe

HCNSO Student Theses and Dissertations

Since the 1970s, loss of herbivores, coral bleaching, pollution, and disease epidemics have reshaped the ecological framework of coral reefs. Staghorn coral, Acropora cervicornis, was a major reef-building scleractinian coral found throughout Florida and the Caribbean that experienced unprecedented population declines primarily due to disease and coral bleaching. These two stressors are coupled; the highest coral disease prevalence occurs after periods of thermal stress caused by increased sea surface temperature. Previous research documented three disease-resistant A. cervicornis genotypes in Panama, but it is unknown if disease-resistant genotypes exist in the Florida Keys. Thermal tolerance has been found to be …

Toxicological Effects Of Commercial Sunscreens On Coral Reef Ecosystems: New Protocols For Coral Restoration, Emilie C. Johnsen

HCNSO Student Capstones

The primary purpose of consumer-grade sunscreen is to protect skin from harmful UVA and UVB rays. This market has grown during the past 80 years, and environmental contamination from increasing amounts of sunscreen compounds have created concern. In particular, impacts on ocean ecosystems have inspired investigations and toxicological research on their effects on marine life. Unfortunately, such studies using marine flora and fauna are scarce, and the impact of chemical exposure to consumer sunscreens is neither adequately measured nor completely understood. In a pilot study by the Coral Restoration Foundation, in situ toxicity exposure to 10 different brands of sunscreens …

Southeast Florida Reef-Wide Post-Irma Coral Disease Surveys, Brian K. Walker

Marine & Environmental Sciences Faculty Reports

Florida’s coral reefs are currently experiencing a multi-year outbreak of coral disease that have resulted in the mortality of millions of corals across southeast Florida, Biscayne National Park, and the Upper and Middle Florida Keys. In early September 2017, Hurricane Irma impacted the entire FRT. The purpose of this project was to conduct field surveys to identify the current state of the coral reefs in southeast Florida and coordinate with other concomitant reef tract efforts to improve the regional understanding of the extent of the disease outbreak and identify recent hurricane injury to direct future restoration. Through a broader partner …

Black Male Persistence In Spite Of Facing Stereotypes In College: A Phenomenological Exploration, Taylor Benjamin Hardy Boyd, Donald Mitchell Jr.

The Qualitative Report

Stereotypes often create threatening environments for Black males on college campuses. This study sought to break the deficit narrative surrounding Black males in college by highlighting how they persisted despite facing stereotypes. Six participants were included in this study. Through interviews and naturalistic observations, we explored how participants articulated their experiences with stereotypes, how they dealt with those experiences, how the experiences shaped future endeavors, and how they used strategies to dispel stereotypes and persist through threatening experiences. Findings suggest (a) the participants dealt with internalized feelings due to stereotypes; (b) stereotypes were reinforced in various ways; and, (c) they …

Age And Growth Of Hogfish (Lachnolaimus Maximus) In Southeast Florida, Ian A. Towne

HCNSO Student Theses and Dissertations

Hogfish (Lachnolaimus maximus; Walbaum 1792) from Southeast Florida were aged using sectioned otoliths and growth rates were calculated using the von Bertalanffy growth equation. The samples were collected from Broward County (n=209); other regions of Southeast Florida (n=18), the Florida Keys (n=35) and Bahamas (n=43). Growth rates were determined for each of these areas and were then compared to previously reported growth rates from other regions including the eastern Gulf of Mexico and Florida Keys. There was significant separation at the 95% confidence level between growth rates from each reagion. The average maximum fork length increased, from the Florida …

Modeling The Conversion Of Normal Protein Prpc Into The Mutated Prpsc In A Prion Disease, Allan Barraza, Hoang (Gwen) Bui

Undergraduate Student Symposium

Gerstmann-Straussler-Scheinker (GSS) is a rare, genetically inherited prion disease caused by a mutation in the prion gene (PRNP). Carriers begin to experience GSS symptoms (similar to Parkinson's and Alzheimer's) during their 30s and 40s. While molecular details concerning the progression of GSS remain largely unknown, the altered conformation of the prion could be directly involved in the aggregation of plaques contributing to progression of the disease. In collaboration with the Milwaukee School of Engineering (MSOE) Center for Biomolecular Modeling - Students Modeling A Research Topic (CBM-SMART) program, we used 3-D modeling and printing technology to examine relationships between this normal …

Bilingualism And Wandering Thoughts: Does Bilingualism Protect Against Mind Wandering?, Maria Morales, Jordana Arauz, Alejandra Quintero, Abraham Yacaman

Undergraduate Student Symposium

Previous research demonstrates that the benefits of speaking two languages extend beyond verbal communication to non-linguistic, executive function (EF) abilities. One component of EF, the ability to inhibit or ignore distracting information, has been shown to be better developed in bilinguals relative to monolinguals. However, little is known whether speaking two languages also enhances the ability to inhibit unwanted or intrusive thoughts. These intrusive thoughts, or mind wandering, have been shown to negatively impact performance on tasks of EF. Thus, the purpose of our study was to compare monolinguals and bilinguals on a self-report measure of mind wandering and performance …

Investigation And Characterization Of Metabolic Rates Of Angiotensin Ii And Associated Bioactive Derivatives In The Renin-Angiotensin System, Chelsea Mathews

Undergraduate Student Symposium

To maintain homeostasis, the renin-angiotensin system (RAS) works to regulate the cardiovascular, renal, respiratory, and neurological systems of the body through activation of both the vasoconstrictive and proliferative arm of ACE/Ang II/AT1R and the vasodilative and antiproliferative arm of ACE- 2/Ang(1-7)/Mas axis. To better understand their interaction, the components of the alternate RAS and the classical RAS in the homeostatic systems of the body are researched and analyzed. One of the significant constituents of the classical pathway is the octapeptide hormone angiotensin II (Ang II). It is a major contributor to vasoconstriction and peripheral vascular resistance through the activation of …

Undetected Exoplanet Populations In The Galaxy, Alisha Rickman, Alex Wild

Undergraduate Student Symposium

The observation of stars and their planets in our galaxy have been made significantly easier with the advent of more efficient telescopes in ideal locations lacking light pollution. Exoplanets, however, are still difficult to identify because of the limitations of technology. Thus, a large fraction of exoplanets has not been detected. In this poster, we explore the populations of exoplanets that slip though current observations. We discuss what exoplanets will be discovered by more sensitive telescopes and advances in observation technologies. We describe the properties of these populations and ultimately show how common these exoplanets are.

Women – Filmed, Rarely Filming, Devon Frazier

Undergraduate Student Symposium

Behind the camera, the Hollywood of today is predominantly male, despite a growing number of women filmmakers in all aspects of the industry. Many capable women filmmakers are marginalized and often confined to making independent films and working in television and streaming media. This sexist bias limits creativity, and the variety of stories that could come out of Hollywood, which in turns robs viewers of varied and fresh storytelling on film.

By exploring the role of women in the Hollywood film industry from its infancy to the present, and highlighting the work of three contemporary directors—Kathryn Bigelow, Sofia Coppola, and …

The Shortage Of Affordable Workforce Housing, Natalie Ramirez

Undergraduate Student Symposium

This research involves an investigation into the shortage of affordable workforce housing in the United States. While the workforce continues to grow, housing development has not kept up for households inthe middle quintiles of their area’s median income, or AMI. Affordability and distance from work arethe main factors the workforce considers important in deciding where to live. The affordable workforce housing shortage is clearly an economic and political issue. Supply and demand dynamics drive up the price of land where it is most sought after, and yet creative solutions exist to offset the increased demand of the workforce. Various government …
