Ugh…Statistics! College Students’ Attitudes And Perceptions Toward Statistics, Drew A. Doyle

Honors Undergraduate Theses

Statistics is a course that is required for a majority of undergraduate college students in a wide variety of majors. It is not just required for Statistics or Mathematics majors, but also for those undergraduate college students majoring in Biology, Engineering, Sociology, and countless other majors. It can often be seen as a daunting course, especially for those who feel that mathematics is not their strongest subject. Students begin to dislike the course before even starting and this can carry on throughout the entirety of the course. This thesis will focus primarily on students’ perceptions and attitudes toward their statistics …

To Gender Identity And Beyond: Does Femininity Lead To A Higher Risk Of Depression?, Dana L. Arnold

Honors Undergraduate Theses

The current study explored the possible links between gender identity, personality, and the experience of depression in a male and female sample. 260 University of Central Florida (UCF) Psychology students completed assessments of depression, “Big Five” personality traits, and gender identity. Correlational analyses revealed significant, positive associations between “Big Five” neuroticism scores and depression scores. Additionally, significant, negative correlations were found between masculinity scores and depression, as well as between femininity scores and depression. Although these correlations were significant, their general effect was small. Overall, additional research must be completed to further examine and validate these findings.

A Structural And Functional Analysis Of Human Brain Mri With Attention Deficit Hyperactivity Disorder, Arjun A. Watane

Honors Undergraduate Theses

Attention Deficit Hyperactivity Disorder (ADHD) affects 5-10% of children worldwide. Its effects are mainly behavioral, manifesting in symptoms such as inattention, hyperactivity, and impulsivity. If not monitored and treated, ADHD may adversely affect a child's health, education, and social life. Furthermore, the neurological disorder is currently diagnosed through interviews and opinions of teachers, parents, and physicians. Because this is a subjective method of identifying ADHD, it is easily prone to error and misdiagnosis. Therefore, there is a clear need to develop an objective diagnostic method for ADHD.

The focus of this study is to explore the use of machine language …

Using Low-Coherence Interferometry To Monitor Cell Invasion In An In-Vitro Model System, Behnaz Davoudi Nasab

Honors Undergraduate Theses

In an optically random system, such as naturally occurring and man-made media, light undergoes pronounced multiple scattering. This phenomenon has shown a remarkable potential in characterizing complex materials. In this regime, scattering occurs from each individual center of the scattering and independent scattering events lead to multiple light scattering. This phenomenon is often described as a random walk of photons and can be modeled in terms of a diffusion equation based on the radiative transfer theory. In this thesis, we used optical path-length spectroscopy (OPS), which is an experimental method to obtain the path-length probability density of the propagating light …

We discuss the C_6v symmetry of the solutions of the wave equation on a hexagonal domain and distinguish between the closed-form and non-closed-form solutions. The closed-form wavefunctions of the transverse magnetic (TM) electromagnetic cavity modes are presented and formulas for the radiated power arising from the uniform part of the AC Josephson current and from the resonant cavity modes are derived. The wavefunctions and angular distribution of radiation from …

Literature Review On The Use Of Nucleic Acid-Based Logic Gates For The Detection Of Human Diseases, Enrique J. Blanco Martinez

Honors Undergraduate Theses

Conventional methods for diagnosis of human disease are, at times, limited in different regards including time requirement, either experimental or data processing, sensitivity, and selectivity. It is then that a Point of Care Criteria, which considers the true utility and usefulness of the device, is employed to propose new diagnostic devices capable of overcoming the aforementioned shortcomings of conventional tools. Nucleic acid, characterized for its predictable base-pairing nature, is considered to be a highly-selective, yet greatly modifiable device. Its behavior is then described through Boolean Logic, where “true” or “false” outputs are mathematically described as “1” and “0”, respectively. This …

Honors Undergraduate Theses

In the field of cancer immunotherapy, NK cells are recognized for their ability to provide a form of innate immunity against tumor cells. However, the average abundance of NK cells in the blood can be as low as 5% of the total lymphocyte population. As a result, it has been a focus to find novel therapies to expand NK cells in vitro while subsequently enhancing the cytotoxicity of these cells. Previously-defined methods include the minimal expansion of NK cells with high levels of cytokines such as IL-2 and IL-15, as well as co-culturing NK cells with feeder cell populations that …

Identifying The Effects Of A Human Dynein Mutation On Gfp-Rab7 Axonal Transport In Embryonic Mouse Neurons, Natalie E. Wilson

Honors Undergraduate Theses

The first dynein mutation found in humans that caused disease was a cytoplasmic dynein 1 heavy chain (DYNC1H1 in humans) p.His306Arg mutation, first described by Weedon et al. in 2011. This mutation caused Charcot-Marie-Tooth (CMT) subtype 2O. CMT has a prevalence of approximately 1 in 2500 people, making it the most common hereditary neuromuscular disorder. Cytoplasmic dynein 1 is used by eukaryotic cells for minus-end directed microtubule-based transport of cargo. One such cargo is Rab7, a late endosomal marker. The purpose of this study is to identify the effects of this mutation on the transport of GFP-tagged Rab7 cargo in …

Atmospheric Entry, Dillon A. Martin

Honors Undergraduate Theses

The development of atmospheric entry guidance methods is crucial to achieving the requirements for future missions to Mars; however, many missions implement a unique controller which are spacecraft specific. Here we look at the implementation of neural networks as a baseline controller that will work for a variety of different spacecraft. To accomplish this, a simulation is developed and validated with the Apollo controller. A feedforward neural network controller is then analyzed and compared to the Apollo case.

Micro-Spectroscopy Of Bio-Assemblies At The Single Cell Level, Jeslin Kera

Honors Undergraduate Theses

In this thesis, we investigate biological molecules on a micron scale in the ultraviolet spectral region through the non-destructive confocal absorption microscopy. The setup involves a combination of confocal microscope with a UV light excitation beam to measure the optical absorption spectra with spatial resolution of 1.4 μm in the lateral and 3.6 μm in the axial direction. Confocal absorption microscopy has the benefits of requiring no labels and only low light intensity for excitation while providing a strong signal from the contrast generated by the attenuation of propagating light due to absorption. This enables spatially resolved measurements of single …

Advanced Castes At The Outset Of Eusociality In Wasps (Vespidae), Patrick Piekarski

Electronic Theses and Dissertations

A dominating and widespread view is that evolutionary change is gradual and waits upon mutation. Likewise, it is thought that workers and queens of eusocial insects diverged gradually and stepwise. That is, rudimentary castes preceded advanced castes. This paradigm hinges on eusociality having evolved once in Vespidae, and primitively eusocial paper wasps lacking ontogenetic caste biasing (differentiation of castes during larval development). Using a phylogenomic approach this study shows strong evidence for two origins of eusociality in vespid wasps, wherein one origin is likely characterized by the sudden appearance of castes with physiological, and perhaps even morphological, differences established before …

Predicting Child Maltreatment Potential In Mothers Who Are Substance-Involved: A Study Of Childhood Adversity, Stress, Affectivity, Emotion Dysregulation, And Emotion Regulation Strategies As Mechanisms Of Action, Amanda Lowell

Electronic Theses and Dissertations

Compared to the general population, parents who are substance-involved are both more likely to have experienced adversity during childhood and to exhibit elevated child maltreatment potential later in life. Within this population, mothers with young children are particularly at-risk. In order to enhance scientific understanding of this phenomenon, this study identified and examined several characteristics that were shown previously to be related to substance misuse and to the experience and perpetration of maltreatment. These characteristics included stress, affectivity, emotion dysregulation, and emotion regulation strategies. The current study examined these variables collectively in order to clarify the mechanisms at play in …

The Effects Of Social Support And Working Alliance On Latino-American Male Combat Veterans, Lloyd Duran

Electronic Theses and Dissertations

The negative effects of traumatic combat experiences on combatants' psychological functioning is well documented in the literature. The Global War on Terrorism (GWOT) has resulted in many veterans returning from deployments with mental health conditions related to trauma exposure, such as posttraumatic stress disorder, depression, general anxiety, and suicidality. Past researchers found significant ethnic differences in psychological functioning, with Latino-American veterans reporting more symptoms of PTSD. Furthermore, Latino-American cultural values place importance on collective orientation and secrecy of mental health concerns which may affect treatment. Thus, this study built on limited research about Latino-American male combat veterans by focusing on …

Consequences Of Altered Short-Chain Carbon Metabolism In Heart Failure, Julie Horton

Electronic Theses and Dissertations

Cardiovascular disease is currently the foremost cause of death within the United States. Heart failure (HF) is a syndrome defined by the inability of the heart to adequately execute requisite pump function in order to deliver nutrients and oxygen to peripheral tissues, irrespective of etiology. One of the most common causes of HF is chronic pressure overload due to hypertension. Ischemic heart disease is also a common driver of HF, often in conjunction with hypertension. Pressure overload initially causes compensatory metabolic changes. Structural changes follow shortly thereafter typically resulting in left ventricular hypertrophy. Eventually, the heart loses the ability to …

Go With The Flow: Patterns Of Connectivity In Low Dispersal Coral Reef Gobies (Coryphopterus Spp.) Throughout The Western Atlantic, Daniel Volk

Electronic Theses and Dissertations

Gene flow is an integral biological process that can mediate speciation. While many consider the ocean to be an open environment, there are many barriers that limit gene flow, particularly in the western Atlantic. I analyzed data from two widespread, coral reef fishes, the bridled goby (Coryphopterus glaucofraenum) and sand-canyon goby (C. venezuelae), throughout their range in the western Atlantic. Using two genetic datasets, mitochondrial DNA (mtDNA) and genomic SNPs, I investigated the evolutionary history of these species and inferred the location and strength of putative barriers. My results suggest that several unique lineages have genetically diverged from one another …
