Quantifying The Success Of Eastern Oyster Pilot Reefs In Brevard County, Florida, Lacie Anderson

Honors Undergraduate Theses

Crassostrea virginica, the eastern oyster, is a native keystone species that inhabits many coastal and estuarine ecosystems along the Atlantic seaboard. Introduction of the eastern oyster into estuarine areas with limited current populations is gaining popularity as a pro-active approach to improve estuarine water quality. In November 2014 and April 2015, a total of five pilot oyster reef treatments were deployed in Brevard County: bagged adult oysters (grown by community members under their docks through oyster gardening) collected in fall 2014 and spring 2015, bagged clean shell, oyster restoration mats, and empty plots (control). Locations of deployment included a …

Public Perceptions Of Birthmothers Of Adopted Children, Bethany I. Wedlund

Honors Undergraduate Theses

A woman who has experienced an unintended pregnancy and chooses to place the child for adoption is known as a birthmother. When faced with an unintended pregnancy, women typically have three courses of action. They may choose to parent the child, terminate the pregnancy, or place the child for adoption. There is limited research on birthmothers themselves or societal perceptions of them.

When it comes to societal perceptions of abortion, religiosity is a significant factor. Contrary to popular belief, many of the women who choose to abort do so in order to preserve the lives of their families. Single mothers …

The Effect Of Climate On Physiology And Immune Function In The Asian Citrus Psyllid, Diaphorina Citri, Grace Avecilla

Honors Undergraduate Theses

The variation in the insect immune system is an important regulator of insect populations and the pathogens they carry. A central component of insect immunity is melanin, whose production creates cytotoxic intermediates that help to protect against a broad spectrum of pathogens. Melanin is also used in insect cuticle where it helps to improve thermoregulation and desiccation resistance, with insects having less melanized cuticles in warmer and more humid environments. Considering that cuticle melanin and immune melanin are formed by near identical biochemical pathways, they are pleiotropically linked (that is, one or more linked genes influence multiple traits). This has …

Evaluating Competition Between Verbal And Implicit Systems With Functional Near-Infrared Spectroscopy, Troy A. Schiebel

Honors Undergraduate Theses

In category learning, explicit processes function through the prefrontal cortex (PFC) and implicit processes function through the basal ganglia. Research suggested that these two systems compete with each other. The goal of this study was to shed light on this theory. 15 undergraduate subjects took part in an event-related experiment that required them to categorize computer-generated line-stimuli, which varied in length and/or angle depending on condition. Subjects participated in an explicit "rule-based" (RB) condition and an implicit "information-integration" (II) condition while connected to a functional near-infrared spectroscopy (fNIRS) apparatus, which measured the hemodynamic response (HR) in their PFC. Each condition …

Identity Development And Sexual Orientation Prejudice, Cassandra Smith

Honors Undergraduate Theses

This study examined the relationships among psychological variables of sexual prejudice, psychological adjustment, and identity development. It was hypothesized that sexual orientation prejudice would be negatively related to psychological adjustment. It was further hypothesized that identity formation would moderate the relationship between sexual orientation prejudice and psychological adjustment. Participants were 200 college students, ages ranged from 18-48 (M = 21.96, SD = 4.87). Sexual orientation for the participants included self-identified labels of Heterosexual (88.5%), Homosexual (6.5%), Bisexual (3.5%), Pansexual (1%), and Demisexual (0.5%). Survey data were collected through a Psychology Research Experience website (SONA). Results revealed a negative correlation between …

Screening For Anticancer Agents To Inhibit Mitotic Kinases And Proliferation Of Metastatic Prostate Cancer Cells, Khoa Nguyen

Honors Undergraduate Theses

Current treatments for prostate cancer (PCa) are marred with high relapse frequency and development of progressively aggressive cancers; developing new treatment options for PCa remains crucial. In this project, a series of synthetic compounds based on natural products will be screened to identify inhibitors for Aurora-A kinase (Aur-A). Aur-A facilitates centrosome separation and bipolar spindle formation during mitosis. Aur-A is overexpressed in metastatic PCa cells, and is a good candidate for targeted therapies. Compound libraries are designed using natural compounds that contain simple structural elements as starting points for developing drug like libraries. High-throughput screening of these libraries will be …

Aptameric Sensors: In Vitro Selection Of Dna That Binds Bromocresol Purple, Derek B. Miller

Honors Undergraduate Theses

Aptamers being used as sensors is an emerging field that has capabilities of being tomorrow’s diagnostic tools. As aptameric sensors have become more popular, their visualization systems have been limited. The majority of today’s aptameric sensors require expensive machinery such as a fluorometer in order to visualize results. We propose a system that will cut the need for instrumentation and be detected via the naked eye. With the selection of an aptamer to bind the pH indicating dye bromocresol purple (BCP) this may be achieved. When rendered active, the binding towards BCP will facilitate a color change from yellow to …

Outcomes Assessment Within Prostate Cancer Interventions For Couples: A Narrative Review, Andrea M. Siguenza

Honors Undergraduate Theses

Current cancer research is beginning to address the psychosocial implications of a prostate cancer (PCa) diagnosis from not just the perspective of quality of life of the patient, but of his partner as well. Such inquiries have created novel intervention programs aiming to alleviate the adverse side effects that a PCa diagnosis may inflict on the couple.
Assessing efficacy of couple-based interventions, however, has been a difficult task due to the lack of homogeneity between studies regarding the operationalization process of primary outcome variables, as well as the instruments being used to measure them. This thesis, in response, aims to …

Representations And Impacts Of Transgender And Gender Nonconforming Ideals In Children's Literature For Young Children, David B. Foresman

Honors Undergraduate Theses

Children’s literature plays a critical role in shaping how children view themselves and the world around them. This is especially true in regards to outgroups such as the transgender and gender nonconforming communities. Transgender individuals have been gaining increased visibility in the past few years. The misconceptions surrounding these topics are not exclusively found outside the classroom. Title IX was expanded to include gender identity as recently as 2014. Yet, much confusion and apprehension is present when discussing the topic of transgender and gender nonconformity, especially in the elementary school classroom. To address these misconceptions, inclusion of these outgroups into …

Exploring Preservice Teacher Attitudes Toward Black Students, Audra L. Greuel

Honors Undergraduate Theses

The majority of the preservice teacher population is young, White, and female; however, the urban school system student population continues to become increasingly diverse, including an increasing population of underserved Black students in urban schools. The racial differences between the preservice teacher population and the urban student population complicates the challenges faced in educating Black students effectively. Teachers and students often encounter misunderstandings, and thus, utilize incompatible styles of classroom management and instruction, often resulting in Black students experiencing difficulties with learning. Many of these complications derive from the profound presence of race, racial difference, and racial inequality throughout U.S. …

Exploring The Therapeutic Roles Of Santeria For Latinx Living In Florida, Amaris J. Santiago

Honors Undergraduate Theses

Mental health services within Latinx communities in the United States has been greatly underutilized. Seekers of mental health support face many barriers including internalized stigmas, misconception of mental health serves and low general knowledge of mental health and wellness. For many Latinx, culturally competent mental healthcare has lacked important elements to how Latinx interpret mental healthcare services. The use of Santería in many in Florida and the United States has supplemented gaps left by formal mental healthcare services. Santería has its own stigmas within Latinx communities were its practiced, forcing many Santeros and seekers to practice in private. Lack of …

The Effects Of A Loving-Kindness Meditation On Positive Emotions, Social Connectedness, And Problem Behaviors In Second And Third Grade Students., Doreen Collins-Mchugh

Electronic Theses and Dissertations

Concerns about K-12 students' mental health and social, emotional, and ethical development have prompted some schools to implement programs designed to promote student well-being and healthy social and emotional functioning. Most of these programs are distinguished as social and emotional learning (SEL) programs and/or character education programs. Although there is growing empirical support for the potential of school-based mindfulness interventions to positively influence students' well-being, the number of school-based mindfulness studies is limited, and the majority of the investigations have focused on students' cognitive rather than affective capacities. Loving-Kindness Meditation (LKM), a mindfulness- and compassion-based practice, is garnering recent attention …

Self-Assembly Of Rous Sarcoma Virus Capsid Protein, Probed By Solid-State Nmr And Tem, Jaekyun Jeon

Electronic Theses and Dissertations

The retroviral capsid protein (CA) is derived from the cleavage of Gag polyprotein during the maturation process, and self-assembles into a polymorphic fullerene-like shell encasing the viral genome materials. The orthoretroviral CAs, for instance, Human Immunodeficiency Virus (HIV) and Rous Sarcoma Virus (RSV) CA, has little similarity in their sequence composition but a common 3D structure. They form distinct capsid assembly in vivo and a range of similar assemblies in vitro. Due to the substantial polymorphism, such assemblies are not amenable for conventional structural biology techniques such as X-ray diffraction crystallography and cryo-electron microscopy (cryo-EM). Solid-state NMR spectroscopy is the …

Zooming In On The Money Shot: An Exploratory Quantitative Analysis Of Pornographic Film Actors, Erin O'Neal

Electronic Theses and Dissertations

Sex work is one of the rare elements of our society that is both accepted and stigmatized. Ironically enough, it is stigmatized without being studied in depth. The truth is we know very little about sex work and even less about pornography—the most legal of genres. While researchers have spent a great deal of time determining the effects that pornography has on viewers, particularly juvenile viewers, little research has been done on the men and women who make pornography. A 43 question survey was created and disseminated to those in the pornographic film industry, both amateur and professional, resulting in …

Degradation Of Hexachlorobenzene, Pentachlorophenol And Pentachloroanisole Using Activated Magnesium In An Acidified Ethanol/Ethyl Lactate Cosolvent System, Amel Garbou

Electronic Theses and Dissertations

For many centuries, chemists have dedicated many labor-intensive hours to improving the quality of life for mankind by developing synthetic methods for the production of compounds which fulfill the needs and meet the demands of society. However, the innovation of such compounds has frequently come at the cost of detrimental side-effects that do not always present themselves until many years, or even decades, following their initial application. Many compounds in this category come in the form of globally-distributed halogenated molecules which are toxic to many living organisms, susceptible to bioaccumulation and resistant to biodegradation processes. Such compounds are classified as …

Habitat Selection In Transformed Landscapes And The Role Of Novel Ecosystems For Native Species Persistence, Lina Maria Sanchez Clavijo

Electronic Theses and Dissertations

To understand native species persistence in transformed landscapes we must evaluate how individual behaviors interact with landscape structure through ecological processes such as habitat selection. Rapid, widespread landscape transformation may lead to a mismatch between habitat preference and quality, a phenomenon known as ecological traps that can have negative outcomes for populations. I applied this framework to the study of birds inhabiting landscapes dominated by forest remnants and shade coffee plantations, a tropical agroforestry system that retains important portions of native biodiversity. I used two different approaches to answer the question: What is the role of habitat selection in the …

Analysis Of Benzopyrenes And Benzopyrene Metabolites By Fluorescence Spectroscopy Techniques, Bassam Al-Farhani

Electronic Theses and Dissertations

Polycyclic aromatic hydrocarbons (PAHs) are some of the most common and toxic pollutants encountered worldwide. Presently, monitoring is restricted to sixteen PAHs, but it is well understood that this list omits many toxic PAHs. Among the "forgotten" PAHs, isomers with molecular weight 302 are of particular concern due to their high toxicological properties. The chromatographic analysis of PAHs with MW 302 is challenged by similar retention times and virtually identical mass fragmentation patterns. The first original component of this dissertation evolves from a high-resolution spectroscopic approach specifically developed to fulfil this gap. Herein, 4.2 K Laser-Excited Time-Resolved Shpol'skii Spectroscopy (4.2K …

Mixed multilevel repeated measures modeling revealed significant overall improvements in many primary (i.e., self-efficacy for managing …

The Role Of Sod1 Acetylation In Neurodegeneration, Michael Kaliszewski

Electronic Theses and Dissertations

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder affecting motor neurons. Cu, Zn superoxide dismutase (SOD1), a cytoplasmic free radical scavenging enzyme, is mutated in familial ALS (fALS) and post-translational modification of the wild-type protein has been associated with sporadic ALS (sALS). Proteomic studies indicate that SOD1 is acetylated at Lys123; however, the role of this modification remains unknown. To investigate its function, we generated antibodies for Lys123-acetylated SOD1 (Ac-K123 SOD1). Sod1 deletion in Sod1-/- mice, K123 mutation, or preabsorption with Ac-K123 peptide suppressed immunoreactivity, confirming antibody specificity. In the normal central nervous system, Ac-K123 SOD1 maps to glutamatergic …

Assessment Of Staphylococcus Aureus Genetics: Clinical Versus Community Epidemiology, Matthew Lawrance

Electronic Theses and Dissertations

Staphylococcus aureus has an historical relationship with anthropogenic environments, particularly hospitals, where infection characteristics differ from community-acquired disease. This has promoted a designation of strains as healthcare or community associated. Despite this affiliation, genetic approaches have failed to support these groupings. In order to establish the genetic relationship between S. aureus from differing anthropogenic environments, I have analyzed the relatedness between three cohorts of S. aureus: nasal carriage isolates from community participants, infectious isolates from hospitals, and a cohort from an uninvestigated environment, an ambulatory clinic. Multilocus Sequence Typing (MLST) and Staphylococcus aureus protein a (spa) repeat regions were analyzed …

Harmful algal blooms caused by the marine microalga Aureoumbra lagunensis have been associated with negative impacts on marine fauna, both vertebrate and invertebrate. Within the Indian River Lagoon (IRL) estuary system along Florida's east coast, blooms of A. lagunensis in excess of 1×106 cells mL-1 have occurred along with higher than average salinities (> 35 PSU) during times of peak reproduction and growth for the eastern oyster Crassostrea virginica. Field and laboratory studies were used to investigate the effects of A. lagunensis and high salinities on early life stages of eastern oysters, late pediveliger to early juvenile. Natural recruitment of …

Development Of Molecularly Imprinted Polymers For Forensic Applications, Sara Martinez

Electronic Theses and Dissertations

In some forensic disciplines various methods of extraction are used to perform analysis. Among these methods, solid phase extraction (SPE) and solid phase microextraction (SPME) are used in fields such as toxicology and explosives analysis. To enhance extraction efficiency in SPE and SPME, molecularly imprinted polymers (MIPs), which are designer polymers, can be more selective for the binding of an analyte or group of analytes that are similarly structured. Separation of analytes from complex mixtures is possible by utilizing these polymers. This may be especially useful in forensic applications where sample sizes may be small and composition may be complex. …

Electronic Theses and Dissertations

This study contributed information for consideration as school districts determine grade span configuration as part of school design. The problem addressed was the extent to which student achievement may be impacted by the transition from one school to another from fifth to sixth grade in Florida public schools in order to provide data to school policy makers and school district administrators and add to the body of knowledge on the grade level configuration that contributed the most to student achievement in sixth grade. This was a causal-comparative study using quantitative data to analyze student scores at the school level for …

Apolipoprotein-Ai Regulates Hepatic Vldl Secretion By Controlling Intracellular Vldl-Trafficking, Bhavesh Gurwani

Electronic Theses and Dissertations

Cardiovascular diseases cause 17 million deaths annually, which is estimated to increase to 23 million deaths by the year 2030. One of the major risk factors for the pathogenesis of cardiovascular diseases is increased secretion of very-low density lipoproteins (VLDL) by the liver; however, reduced VLDL-secretion causes fatty liver disease. Synthesis and secretion of VLDL by the liver plays an important role in maintaining overall lipoprotein homeostasis. Assembly of VLDL occurs along with the expression of apolipoproteinB-100 (apoB100) and its lipidation at the endoplasmic reticulum (ER) level. Once formed in the ER lumen, the nascent VLDL is transported to the …

Involvement Of Mirnas In The Development Of Androgen Independent Prostate Cancer, Richard Ottman

Electronic Theses and Dissertations

Development of resistance to androgen deprivation therapy (ADT) is a major obstacle for the management of advanced prostate cancer. Therapies with androgen receptor (AR) antagonists and androgen withdrawal initially result in tumor regression but development of compensatory mechanisms including AR bypass signaling leads to tumor re-growth, independent of circulating androgens. The result is the emergence of castration resistant prostate cancer (CRPC), a highly morbid disease exhibiting aberrant expression of many protein-coding and non-coding genes. Under the umbrella of non-coding RNAs is a class of small regulatory RNAs referred to as microRNAs (miRNAs). MicroRNAs are believed to function in the maintenance …

Preliminary Investigation Into Biological Sex Estimation Using Trace Element Analysis In Human Hair, Abigail Woltering

Electronic Theses and Dissertations

In forensic anthropology the estimation of biological sex of unidentified human remains is critical, as it essentially halves the number of potential identities. Sex estimation is also important in bioarchaeology, because the creation of the biological profile is critical to the interpretation of different sociocultural aspects of past populations. Furthermore, certain aspects of the biological profile are sex specific, so it is important to be able to accurately determine biological sex (France 1998). Typically, biological sex is estimated by assessing sexually dimorphic differences within the pelvis and skull. However, because sexually dimorphic differences arise during puberty it is difficult, and …
