Workspace And Kinematic Modeling And Analysis Of Semi-Robotic Laparoscopic Surgery, Immanuel E. Girgis

Honors Undergraduate Theses

Laparoscopic Surgery has been revolutionized by the world of Surgical Robotics. Robot-Assisted Surgeries have been proven to have many advantages over the fundamental, traditional "by-hand" procedures previously conducted, and still currently being done for certain operations. Robot-assisted surgery may offer benefits to patients through the use of minimally invasive techniques, which may result in reduced blood loss, reduced blood transfusion, fewer complications, reduced postoperative pain, shorter hospital stays, and reduced recovery times (Ho et al., 2011). Studies have proven that robotic surgery may lead to patients recovering faster depending on the timeframe and the type of procedure (Tang et al., …

Using Genetics In A Model Organism To Understand Polyamine Transport, Victoria A. Millington

Honors Undergraduate Theses

Polyamines are small positively charged molecules that control major vital cellular processes including cell growth and proliferation, gene expression, protein production and cell death. Cells can obtain polyamines by making them (biosynthesis) or bringing them into the cell from the outside (transport). Cancer cells require high levels of polyamines to sustain their rapid growth, and depletion of polyamines slows the growth of malignant cells. An FDA approved drug, difluoromethylornithine (DFMO), blocks biosynthesis but is often ineffective because tumor cells respond by increasing transport of polyamines. Thus, a dual therapy that simultaneously targets polyamine biosynthesis and transport is needed. The mechanism …

Fish Weirs Et Alia: A Gis Based Use-Analysis Of Artificial, Pre-Columbian Earthworks In West Central Llanos De Mojos, Bolivia, Charlotte A. Robinson

Honors Undergraduate Theses

This study employed a GIS-based use-analysis on a network of recently mapped pre-Columbian earthworks lying on the west side of a Bolivian floodplain. This wetland region, called Llanos de Mojos, is home to many different types of artificial mounds that served different roles for the ancient communities who constructed them thousands of years ago. This new set of features, which was mapped by volunteers of the Proyecto Sistemas Informaticas Geograficas y Arqueologicas del Beni (ProSIGAB) was purported to be a network of fish weirs, linear earthworks built in rivers or floodplains that are designed to trap fish by exploiting seasonal …

The categories of DV were broken down into verbal abuse and physical abuse, along with a third category of juveniles that witnessed both forms of abuse within their households. This study compared the prevalence of anxiety in juveniles when faced with the different instances of DV through the use of data collected from a longitudinal study conducted by the Pathways to Desistance Project. The goal of the study was to further …

Gastrointestinal Symptoms And Belly Pain During The Phases Of The Menstrual Cycle In Healthy Young Females, Preethashree Anbukkarasu

Honors Undergraduate Theses

There are significant differences between the incidence of gastrointestinal (GI) symptoms between males and females. A recent review found that females report having more severe GI health problems compared to males. One explanation for the higher reporting rates of GI symptoms in females could be attributed to menstrual cycle influences rather than GI processes.

This research aims to examine the relationship between how gastrointestinal (GI) symptoms experienced by women covary with the different stages of the menstrual cycle. Additionally, a secondary purpose is to determine the moderating effect of health anxiety on the severity of menstrual and GI symptoms.

Responses …

The Moderating Effect Of Organizational Policies And Procedures In Relation To The Consequences Of Sexual Harassment Of Women, Nicole Aranda

Honors Undergraduate Theses

Sexual harassment is common in the workplace and leads to negative outcomes for individuals and organizations. Previous research has shown that turnover is a negative outcome of sexual harassment. Organizations can implement policies and procedures, but little research exists examining the impact of these policies on employee perceptions and intentions. Thus, the aim of this study is to examine perceived enforcement of organizational policies and procedures as a moderator of the relationship between sexual harassment and turnover intentions. Social exchange theory is used to explain this concept between women from male-dominated professions and gender-balanced professions. Participants were 66 employed females …

A Right To A Pollution-Free Environment Through The Right To Life, Natalie S. Mousa

Honors Undergraduate Theses

Since humans have existed on Earth, the environment has been one of the primary resources contributing to humans' ability to live life adequately. Pollution has not only destroyed natural life, but it has also diminished humans' right to life. The United Nations 1966 International Covenant on Civil and Political Rights (ICCPR) guarantees "every human being has the inherent right to life," but how can one exercise this right in an environment that is degrading through pollution? This is the basis of which this thesis is surrounded; the issue of environmental pollution hindering humans' right to life. Thus, this thesis …

Reviving Mozart With Intelligence Duplication, Jacob E. Galajda

Honors Undergraduate Theses

Deep learning has been applied to many problems that are too complex to solve through an algorithm. Most of these problems have not required the specific expertise of a certain individual or group; most applied networks learn information that is shared across humans intuitively. Deep learning has encountered very few problems that would require the expertise of a certain individual or group to solve, and there has yet to be a defined class of networks capable of achieving this. Such networks could duplicate the intelligence of a person relative to a specific task, such as their writing style or music …

The Persistence And Disproportionate Impact Of Felon Disenfranchisement, Rebecca Jaffe

Honors Undergraduate Theses

This paper seeks to understand the persistence of disenfranchisement policies and the disproportionate impact these policies have on marginalized groups of the American electorate, specifically black Americans. Felon disenfranchisement, or the restriction of voting rights for criminals convicted of felonies, has been a long-standing policy throughout the United States. Using public opinion data from the 2014 General Social Survey (GSS), this paper analyzes how certain characteristics, such as race, age, and political party identification, can influence opinions about democratic rights and whether criminals should lose theirs once convicted. The results of this analysis could help explain why disenfranchisement policies have …

The Role Of Islam In Establishing Women's Rights In The Muslim World, Assad Khan

Honors Undergraduate Theses

This paper examines the literature surrounding women's rights in the Muslim world to determine the factors that have contributed to the oppression of women in the Muslim world and to understand the role that different interpretations of Islam can have on either restricting or improving the status of women in the Muslim world. The practices of Muslim people as a population deviate from what is prescribed by Islam in some cases, contributing to the misconception that the restrictive practices toward women in many Muslim-majority countries are founded in Islamic teachings. Factors such as individual levels of religiosity and adherence to …

A Model For Assessing Staff Resilience To Improve Organizational Resilience In Emergency Departments, Stefani Baz

Honors Undergraduate Theses

Organizational Resilience is defined as the ability of an organization to anticipate sudden disruptions, effectively respond, and adapt in a changing environment to deliver its objectives, as well as successfully recover. In order to increase resilience at an organizational level, it is important to understand how individuals collectively contribute to resilience capability of an organization. Emergency Departments (EDs) are considered to be particularly well suited to investigating resilience capability due to their highly unpredictable and complex operating environment. Further, the resilience capability of EDs and their staff is suggested to be essential to successful delivery of safe, high-quality, and timely …

Covid-19 Infection In Hypertensive Patients In Correlation With Race, Elizabeth Durkin

Honors Undergraduate Theses

Disparities in healthcare exist in the U.S., particularly between different racial categories. This study investigated the frequency of COVID-19 cases and hypertension cases among five different racial groups (White, Black, Asian, Native American, and Native Hawaiian). The study also examined the correlation between COVID-19 and hypertension. It was hypothesized that, because of genetic predisposition to certain diseases and existing socioeconomic barriers, Black populations would have the highest rates of both COVID-19 and hypertension. It was also proposed that a positive correlation exists between COVID-19 and hypertension frequency. To test this, the Kaiser Family Foundation's data for COVID-19 cases and race …

All Good Things Must Come To An End: Finding The Connection Between Citizenship Pressure, Organizational Citizenship Behaviors, And Job-Related Affective Well-Being, Skylar D. Oney

Honors Undergraduate Theses

A plethora of extant research focuses on the positive outcomes of organizational citizenship behaviors (OCB). However, there has been a relatively recent shift of focus that sheds light on the changing parameters and workplace perceptions of what such behaviors entail, as well as their adverse outcomes. As organizations and their employees endure changes, work expectations have consequently changed through differing perceptions of job tasks that individuals feel required or obligated to do, even when it is not included in their formal job description. Such feelings point to the concept of citizenship pressure (CP), which this thesis further explores and adds …

The Relationship Between Campus Involvement And Civic Engagement, Sheina L. Koolik

Honors Undergraduate Theses

The purpose of this study is to investigate if campus involvement, either in high school or college, has a relationship with civic engagement after college. Current UCF students, who have at least finished their first year, will be surveyed about their high school involvement to determine if it is related to their college engagement; and, recent UCF Alumni, graduated between 2014-2018, will be surveyed to determine if there is a relationship between campus engagement and civic life after graduation. As well, the data will review other key aspects like campus location, race, gender, international status, motivations, religious affiliations, etc. The …

Development And Characterization Of Flow Independent Fuel Injectors, Michael W. Kwara

Honors Undergraduate Theses

Jet-in-crossflow is an interaction between a fuel jet and air crossflow commonly found in jet engines. The crossflow is used to break up or atomize the fuel jet for downstream combustion. This interaction between fluids while at low speeds, is predictable, varies greatly at higher speeds. This investigation seeks to (1) create a mechanism for jet-in-crossflow, using mechanical pintles, that is independent of velocity to help increase the predictability and reliability of jet engines and (2) identify key design parameters that will lead to flow independence. Parameters investigated in this experiment include pintle height, angle, and percent of pintle coverage …

Designing An Expressive Writing Unit For Students With Asd In Mind: The Synthesis Of Social-Emotional Learning And Writing Strategy Instruction, Maya Govea

Honors Undergraduate Theses

In general education classrooms across the United States, students with Autism spectrum disorder (ASD) learn how to write and cultivate their writing skills. Teachers of students with ASD have the unique responsibility of carrying out effective instruction to all students. However, the growing body of research around evidence-based practices and approaches for students with ASD is limited. Two effective practices that have shown positive statistical significance for students with ASD are the self-regulated strategy development model (SRSD) and the social-emotional learning (SEL) framework. General education instruction faces a research-practice gap because of the widespread lack of strategy instruction and lack …

Domestic Migrant Workers In Lebanon: Between Precarity And Resiliency, Jasmine L. Masri

Honors Undergraduate Theses

The proliferation in the number of domestic migrant workers (DMWs), who travel from poorer countries to work in homes in wealthier countries, represents an essential dimension of globalization in the 21st century. This project focuses on DMWs in Lebanon. In an increasingly globalized world, the study of DMWs, who number around 250,000 in Lebanon (Amnesty International, 2019), provides a critical case to understand how the transborder movement of humans generates unique and challenging human rights issues. Lebanon practices the kafala system, which is prevalent in other Middle Eastern countries and makes foreign workers legally dependent on their employment. This system …

The testing facility is located at the University of Central Florida in the PERL (Propulsion and Energy Research Lab) facility. The facility allows for modeling an industrial turbine combustor, specifically an axial staged combustor with a Jet-In-Crossflow …

Disease And Democracy: Understanding The Impact Of Disease Burden On Civil Liberties And Civil Society In Sub-Saharan Africa, Abigail E. Reynolds

Honors Undergraduate Theses

What is the impact of disease burden on democracy in sub-Saharan Africa? Despite increasing interest in the implications of health crises for state stability, there has been a dearth of literature exploring the relationship between disease burden more generally and democracy specifically. This thesis takes a comprehensive approach to bridge this gap in the literature. Using quantitative and qualitative methods, it draws on data from the Global Burden of Disease database and the Varieties of Democracy (V-Dem) dataset to analyze this relationship. The diseases studied are categorized as long-wave (e.g., HIV/AIDS and tuberculosis), short-wave (e.g., Ebola and lower respiratory infections), …

The Stability Of Two-Dimensional Cylinder Wakes In The Presence Of A Wavy Ground, Matt Duran

Honors Undergraduate Theses

The following study investigates hydrodynamic stability for two-dimensional, incompressible flow past a cylinder and compares it alongside four different variations of a wave-like ground introduced within the wake region of the cylinder wake. These different variations include changing the distance of the cylinder both horizontally from the wave-like structure and vertically from the ground. The geometry and meshes were initially constructed using GMSH and imported into Nektar++. The baseflows were then obtained in Nektar++ using the Velocity Correction Scheme, continuous Galerkin method, and Unsteady Navier Stokes solver. Then, the Implicitly Restarted Arnoldi Method driver was used to retrieve the various …

Utilizing Fitts' Law To Examine Motor Imagery Of Self, Other, And Objects, Sean D. Hinkle

Honors Undergraduate Theses

Past research has indicated that motor imagery, or imagined movement, follows Fitts' law similarly to physical movement. Additionally, motor imagery has been shown to improve real motor performance in multiple contexts, showcasing a remarkable connection with real motion. The current study examines how the subject of motor imagery, imagining oneself, another person, or an object, impacts this faithfulness to real movement, specifically in following Fitts' law. Participants viewed 2D photos of a virtual environment with an "X", a humanoid, or a disc facing a gate at 6 distances and 4 widths for 24 combinations. Each combination was repeated twice randomly …

Development Of Lifting Line Theory For The Fanwing Propulsion System, Christopher Kaminski

Honors Undergraduate Theses

The FanWing propulsion system is a novel propulsion system which aerodynamically behaves as a hybrid between a helicopter and a fixed wing aircraft, and if the knowledge base with regards to this novel concept can be fully explored, there could be a new class of aircraft developed. In the current research, only 2D CFD studies have been done for the FanWing, hence the 3D lift characteristics of the FanWing have been unknown thus far, at least in the theoretical domain. Therefore, it was proposed to develop a modified Prandtl's Lifting Line Theory numerical solution and a CFD solution, comparing the …

Phototransduction Components In The Visual System Of Hard-Bodied Ticks, Arimar J. López Limas

Honors Undergraduate Theses

Ticks are terrestrial invertebrate parasites that attach to their hosts to feed on their blood. Ticks are composed of three families: Ixodidae, Argasidae, and Nuttalliellidae. Ixodid ticks include members of the genera Amblyomma, Ixodes, Haemaphysalis, Hyalomma, Dermacentor, and Rhipicephalus. Ticks can transmit diseases to animals and humans, making them an important organism to study. Current tick-bite mitigation strategies include acaricides (harmful if misused), and CO₂ traps (effective in decreasing tick abundance, but costly to use). Since the visual system of ticks has not been studied extensively, I expect that by studying their visual system, alternative tick-bite mitigation …

The Relationship Between Creative Hobbies And Visual Spatial Ability, Victoria Alexander

Honors Undergraduate Theses

Recent developments in educational practices have identified the teaching of STEM (science, technology, engineering, and mathematics) areas as important, but this emphasis on STEM fields has sacrificed educational focus on the Arts (Cohen, 2016). This is a significant loss, not only in terms of the loss of humanities education in itself, but through the potential loss of foundational skills through practice in artistic areas. The current paper explores this idea by investigating the correlational relationship between visual spatial abilities and participation in a variety of creative activities. Spatial ability is known to be a cognitive skill that underlies success in …

The Mobilizer And The Mobilized: An Exploration Of "Latinx", Marisa E. Norzagaray

Honors Undergraduate Theses

In this project, I endeavor to bridge the gap between these two by analyzing "Latinx" as a symbol that functions distinctly when employed as a personal or group identity. My argument for this thesis can be broken into two main parts: its significance as an identity, and its tangibility. As a group identity, I argue "Latinx" represents a social movement for liberation, visibility, and minority allyship. While this is not unconnected to its personal meaning, individual embodiment of the term involves the performance and realization of the intersectional. In other words, it gives those with overlapping queer and Latina/o identities …

Physicians And Their Patience: Redefining Healthcare Relationships Through Readability Optimization, Rachel V. Ball

The present study takes legibility research and extends it to the medical setting. Internal Medicine Physicians from UCF developed six passages of medical text detailing a History of Present Illness (HPI) Report from an emergency department as well as comprehension questions for the purpose of our study. In our study, we first presented non-medical passages and comprehension questions in six common fonts to identify participants' individual fastest and slowest fonts. We then gave participants medical passages in both their best and worst fonts while measuring reading speed and comprehension. This study was delivered to a population of Amazon Mechanical Turk …

Simulating Systematic Errors In Exoplanetary Transits For The James Webb Space Telescope, David C. Wright Iii

Honors Undergraduate Theses

The James Webb Space Telescope (JWST) is a next-generation space telescope that will be capable of making transformative observations of planetary transits. As its launch date grows ever closer, it becomes imperative that astronomers have access to accurate simulations of JWST observations in order to best plan observations and devise data analysis pipelines. Unfortunately, available simulation tools do not provide the most accurate or realistic simulations, including noise and systematic errors. In this thesis, I present an open-source time-domain simulator of planetary transits that is capable of accurately modeling these effects in observations made by JWST.

An Application Of Economic Norms Theory To Brazilian Corruption, Nina B. Neto

Honors Undergraduate Theses

This study aims to explore the relationship between clientelistic economies and systemic corruption under the framework of Economic Norms Theory. Pointedly, it examines the evolution of contractual mortgage credit as a percentage of GDP (representing the growth of a non-self-enforcing contract market) compared to both actual and perceived levels of corruption in Brazil in order to assess whether Brazil is exemplary of a transitioning economy under the theory of Economic Norms. The hypothesis of this paper is two-fold. First, I expect that as mortgage credit as a percentage of GDP generally increases, actual corruption will decrease. Secondly, I expect that …
