Recovery In Teachers: Barriers, Facilitators And The Relationship To Physical Stress Symptoms, Amber A. Blatchford
Honors Undergraduate Theses
Previous research has shown that teachers are at risk of experiencing significant work-related stress. Recovery is seen as a way to unwind from work stress caused by a myriad of stressors. This study examines the mechanisms of teacher recovery and their relationship to physical stress symptoms. Fifty high school teachers were recruited to participate from schools in South Florida. Physical stress symptoms were measured using a self-report survey called the Physical Symptoms Inventory (PSI) , which took place directly after the open-ended question portion of the survey. A multiple linear regression analysis was conducted to assess any connection between the …
Non-Alcoholic Fatty Liver Disease And The Gut Microbiome: The Effects Of Gut Microbial Metabolites On Nafld Progression In A 2-Organ Human-On-A-Chip Model, Rachel H. Boone
Honors Undergraduate Theses
Using a novel, adipose-liver, two-organ, human-on-a-chip system, the metabolic disease non-alcoholic fatty liver disease was modeled. This model was then used to test the effects of the gut microbiome on NAFLD progression. Two products of the gut microbiome, Trimethylamine-n-oxide and butyrate, were selected as representatives of potentially harmful and potentially beneficial compounds. A dose response, adipocyte and hepatocyte monocultures controls, and HoaC systems were run for 14 days. Through this experimentation, it was found that a dysbiosis of the gut microbiome could be influencing NAFLD progression. Additionally, further development and discovery regarding adipose-liver systems was added to the ongoing conversation …
Polarization Dependence Of High Order Harmonic Generation From Solids In Reflection And Transmission Geometries, Erin L. Crites
Polarization Dependence Of High Order Harmonic Generation From Solids In Reflection And Transmission Geometries, Erin L. Crites
Honors Undergraduate Theses
High harmonic generation (HHG) is a process that occurs when an intense laser interacts with a material and generates new frequencies of light. HHG has many practical applications, namely as a spectroscopy technique and source for high frequency light and attosecond pulses. While HHG has been done extensively in gases, HHG in solids is a relatively new field. Solids are appealing as an HHG medium as they require much simpler equipment and are subsequently much more compact, and thus may have a variety of applications previously inaccessible to gas-phase HHG. However, the generation mechanism of HHG in solids has not …

Performance In Vr, Gabriela N. Gonzalez
Honors Undergraduate Theses
Psychologists once believed that memory was the result of a single-unitary memory system, and that memory was representative of a video recording. However, recent research has found that memory is malleable, and different factors can attribute to the accuracy of memory. Factors include internal bias, time since event, level of rehearsal, and outside influences. Specifically, the concept of false memories in regards to eyewitness testimony has garnered the attention of researchers. Prior research regarding false memories has looked at the impact of leading questions on memory accuracy. This study aims to explore the impact of leading questions on false memories …

Development Of A Computer Algorithm For Generation Of Primers For Nucleic Acid Sequence Based Amplification (Nasba), Rohit Karnati
Development Of A Computer Algorithm For Generation Of Primers For Nucleic Acid Sequence Based Amplification (Nasba), Rohit Karnati
Honors Undergraduate Theses
Nucleic acid sequence based amplification (NASBA) is a primer based isothermal method of RNA/DNA amplification. Currently, primer design for NASBA has been restricted to hand creating sequences of oligonucleotides that must follow a set of rules to be compatible for the amplification process. This process of hand-creating primers is prone to error and time intensive. The detection of mutants, post amplification, also offers a benefit in point of care scenarios and the design of hybridization probes for sequences in the region of amplification is also an erroneous and time intensive process. By creating a program to design primers and hybridization …

Assessing 3d Printability Of Bioinks, Nicole Ramirez
Honors Undergraduate Theses
The field of tissue engineering (TE) is continuously improving through the use of additive manufacturing techniques (AM) such as three-dimensional (3D) bioprinting. The 3D bioprinter has significantly gained attention in the TE field because it is more efficient than regenerative medicine and is readily available as opposed to organ transplants. Working like a conventional 3D printer, the 3D bioprinter is able to dispense material layer by layer from the bottom up with the printing head able to move in the X, Y, and Z direction. This movement allows for the fabrication of structures with complex geometries. In this study, the …
How Great Power Politics Influences Refugee Policy: Assessing The U.S. Foreign Policy Implications Of Differing Responses To The Venezuelan Migration Crisis In Colombia, Peru, And Brazil, Suhan M. Rosario
Honors Undergraduate Theses
Why are Venezuelan Migrants accepted in neighboring Colombia, but not in other countries in South America? It is true that Colombia and Venezuela are similar in language, culture, and customs, but this is true across the continent. There has been literature published on the size of the crisis, and where they are going. Here, I will assess why the Colombian government is more accepting of Venezuelan migrants, even when this is not popular in Colombia or any other country in South America.
My argument is that US foreign policy has caused Colombia to be more accepting of Venezuelans than neighboring …
The Impact Of Virtual Reality On Chronic Pain, Alexis Whitehead
The Impact Of Virtual Reality On Chronic Pain, Alexis Whitehead
Honors Undergraduate Theses
Chronic pain remains a prevalent problem across the United States. Chronic pain does not seem to have a function and relief of this symptom remains elusive for many sufferers. Virtual reality has been used as an adjunct therapy to decrease acute pain with promising results, but there is little research on whether virtual reality could be used as a successful intervention for those with chronic pain. Virtual reality has few side effects, so it warrants consideration for the treatment of chronic pain. There is growing evidence that there is potential for virtual reality to produce desired results with patients having …

An Investigation Into Provider Communication At Ucf And The Impact Of Health Literacy On Teach Back Outcomes, Shreya L. Atmakuri
An Investigation Into Provider Communication At Ucf And The Impact Of Health Literacy On Teach Back Outcomes, Shreya L. Atmakuri
Honors Undergraduate Theses
The most important aspect of an encounter between a patient and his or her provider is the patient's ability to understand and implement the treatment plan and self-care instructions conferred by the provider. However, the literature in the field of patient-provider communication reveals that there is a noticeable gap in health literacy in certain patient populations that impairs their ability to understand pre-, during, and post-encounter paperwork, terminology, treatment plan, and critical self-care instructions. This has been shown to have detrimental consequences on patient health outcomes. The teach-back method, in which providers request patients to repeat key information discussed during …

Nanopore-Based Metagenomic Comparison Of Airway Colonizers Between Cystic Fibrosis Patients And Healthy Individuals, Anita Samadabadi
Honors Undergraduate Theses
Cystic fibrosis (CF) is an autosomal recessive genetic disorder involving a mutation in the CF transmembrane conductance regulator protein (CFTR), which causes dysfunctional transport of chloride ions across cell membranes. CF affects multiple body systems and a few of its symptoms include chronic cough, difficulty breathing, obstructive airway disease, bacterial pulmonary infections, maldigestion, malabsorption, pancreatitis, and male infertility. Until recently, treatment options have been limited to alleviating symptoms, but a new classification of drugs, CFTR modulators, provide an opportunity to slow the progression of the disease and improve clinical outcomes. The effect of CFTR modulators may be attributed to the …
Left Ventricular Strains During Late Filling In A Preclinical Model, Saar Peles
Left Ventricular Strains During Late Filling In A Preclinical Model, Saar Peles
Honors Undergraduate Theses
Understanding the mechanisms governing left ventricular function and dysfunction is critical to analyze cardiovascular disorders and gaining insights into possible therapies. Left ventricular function can be evaluated using Magnetic Resonance Imaging (MRI). Cardiac displacements and corresponding strains are then computed from the imaging data. In measuring and assessing the left ventricle’s motion, images are taken either in the short axis (top-down) or long axis (side) views. In this project, we will use DENSE MRI data, which measures the displacements of individual tissue voxels during the cardiac cycle.
After extracting the myocardial tissue by segmenting the MR images, strains are computed …
Systematic Literature Review Of Cognitive Behavioral Treatments For Patients With Classical, Secondary, And Idiopathic Trigeminal Neuralgia, Linnea B. Herzog
Systematic Literature Review Of Cognitive Behavioral Treatments For Patients With Classical, Secondary, And Idiopathic Trigeminal Neuralgia, Linnea B. Herzog
Honors Undergraduate Theses
Trigeminal neuralgia is a painful neuralgia with a complicated pathology that is not clearly understood. Due to the ambiguity of the condition, patients often have to search for medical providers that specialize in trigeminal neuralgia, and even with the guidance of a specialist, some patients do not respond well to treatment.1 Despite the uncertainty surrounding the specifics of the disease, there are treatments available that can provide some level of pain relief for patients suffering from this disorder. When a patient does not respond well to medical therapy, surgery can be the next appropriate step in patient care management. …
Reviewing Constitutionality Of Time Spent On Death Row Under Eighth Amendment Jurisprudence, Angie Richardson
Reviewing Constitutionality Of Time Spent On Death Row Under Eighth Amendment Jurisprudence, Angie Richardson
Honors Undergraduate Theses
Under the Eighth Amendment, the death penalty is in and of itself not considered cruel and unusual punishment. Although the death penalty is frequently attacked for the numerous death row exonerations (more than 150 in the United States alone), lack of evidence supporting the idea that the death penalty deters crime, and marginalized groups being more likely to receive this sentencing, the death penalty still remains on solid constitutional ground. In fact, the arguments that pose the biggest threat to the constitutionality of the death penalty tend to revolve around the potential risk of substantial pain while executing an offender, …
Ultra-Low Power Circuits And Architectures For Neuromorphic Computing Accelerators With Emerging Tfets And Rerams, Jie Lin
Electronic Theses and Dissertations, 2020-2023
Neuromorphic computing using post-CMOS technologies is gaining increasing popularity due to its promising potential to resolve the power constraints in Von-Neumann machine and its similarity to the operation of the real human brain. To design the ultra-low voltage and ultra-low power analog-to-digital converters (ADCs) for the neuromorphic computing systems, we explore advantages of tunnel field effect transistor (TFET) analog-to-digital converters (ADCs) on energy efficiency and temperature stability. A fully-differential SAR ADC is designed using 20 nm TFET technology with doubled input swing and controlled comparator input common-mode voltage. To further increase the resolution of the ADC, we design an energy …

Chemometric Analysis Of Multidimensional Fluorescence Data Recorded From Benzo[A]Pyrene Metabolites In Shpol'skii Like Matrixes, Mohammadreza Chehelamirani
Electronic Theses and Dissertations, 2020-2023
This dissertation extends the application of Shpol'skii spectroscopy to polar metabolites in polar organic solvents. For the first-time, we reported experimental evidence on the line-narrowing effect caused by primary alcohols on the spectral features of PAH metabolites at 77 K and 4.2 K. The effect of primary alcohols (RCH2OH) on the 77 K and 4.2 K fluorescence characteristics of PAH metabolites showed the best spectral narrowing when matching the length of the alkyl group (R) of the primary alcohol to the length of the n-alkane that best fitted the dimensions of the parent PAH. The spectral narrowing and the fluorescence …
Inertial Orbit Estimation Using Multiple Space Based Observers: A New Measurement Model, James Hippelheuser
Inertial Orbit Estimation Using Multiple Space Based Observers: A New Measurement Model, James Hippelheuser
Electronic Theses and Dissertations, 2020-2023
Presented within this work is a new method for inertial orbit estimation of an object, either known or unknown, adaptable to a network of low-cost observation satellites. The observation satellites would only require a monocular camera for line of sight measurements. Using the line of sight measurements of each observer, a pair of orthogonal geometric planes that intersect both the observation satellite and the target are created. The intersection of the two planes in the inertial frame defines the new measurement model that is implemented with multiple observation nodes. Total system observability is analyzed and the instantaneous (per node) observability …
