Discontinuous Galerkin Methods For Compressible Miscible Displacements And Applications In Reservoir Simulation, Yue Kang

Dissertations, Master's Theses and Master's Reports

This dissertation contains research on discontinuous Galerkin (DG) methods applied to the system of compressible miscible displacements, which is widely adopted to model surfactant flooding in enhanced oil recovery (EOR) techniques. In most scenarios, DG methods can effectively simulate problems in miscible displacements.
However, if the problem setting is complex, the oscillations in the numerical results can be detrimental, with severe overshoots leading to nonphysical numerical approximations. The first way to address this issue is to apply the bound-preserving
technique. Therefore, we adopt a bound-preserving Discontinuous Galerkin method
with a Second-order Implicit Pressure Explicit Concentration (SIPEC) time marching
method to …

Anaerobic Reductive Bioleaching Of Manganese Ores, Neha Sharma

Dissertations, Master's Theses and Master's Reports

Manganese extraction by biological methods is a green and economical way to produce manganese from low as well as high grade manganese ores. This is especially important for US ores, which are primarily either small in extent, low-grade with a high iron content, or both. They are therefore not suitable for conventional mining, which is very capital-intensive and requires a large up-front investment and are therefore imported at high costs. The goal is therefore to develop a process that can be applied at small scales, with minimal startup costs, and low equipment and labor requirements. It is also critical to …

Recovering Access Control Via Disk Forensics On Low-Level Flash Memory, Caleb J. Rother

Dissertations, Master's Theses and Master's Reports

In the history of access control, nearly every system designed has relied on the operating system (OS) to enforce the access control protocols. However, if the OS (and specifically root access) is compromised, there are few if any solutions that can get users back into their system efficiently. In this work, we have proposed a novel approach that allows secure and efficient rollback of file access control after an adversary compromises the OS and corrupts the access control metadata. Our key observation is that the underlying flash memory typically performs out-of-place updates. Taking advantage of this unique feature, we can …

Novel Analytical Approaches For The Study Of Energy And Nutrient Flow In Streams, Michelle Catherine Kelly

Dissertations, Master's Theses and Master's Reports

This dissertation applied novel modeling, experimental and statistical approaches to overcome the challenges of measuring and analyzing energy and nutrient cycling in streams through 3 studies: (1) determining the predictors of respiration and denitrification in streams across the United States, (2) simultaneous estimation of denitrification and nitrogen (N) fixation rates, and (3) the impact of C lability metrics on the interpretation of C degradation in DOM incubation experiments. In the first study, I used predictive modeling approaches to show that respiration and denitrification were positively correlated across the landscape but were predicted by factors at different spatial scales. Denitrification rates …

The New Antisemitism, Edgar G. Soto

Honors Undergraduate Theses

Following the Second World War, antisemitism appeared to be on a decline. Presently, however, there is an uptick in antisemitic hate crimes, worldwide. Modern-day Islamic antisemitism in particular is in large part recycled European Christian antisemitism adapted for Islamic audiences and intensified by the ongoing Arab-Israeli conflict. This iteration of anti-Jewish bigotry is not the same as the “old,” but neither is it different. As will be explained, antisemitism has, throughout history, amounted to an anomaly in Islamic culture and in what may be called “normative” Islam.

Indeed, Muslims and Jews lived together amicably for centuries. In fact, within dar-al-Islam, …

The Association Between Patient Race/Ethnicity/Culture, Physician-Patient Communication, And Patient Outcomes: A Systematic Review, Maazen Khan

Honors Undergraduate Theses

Research shows that health disparities exist among patients of varying races, ethnicities, and cultures in the United States. Numerous studies have suggested that these disparities may be partly associated with physician-patient communication. The larger project that this thesis is a part of is a mixed-methods analysis of physician-patient communication across patient race, ethnicity, and culture. This thesis specifically excluded qualitative studies and focused on how such communication can affect health outcomes. Sixty-nine studies were identified and appraised for quality. Of these, only four associated physician-patient communication with the health outcomes of patients. These studies had inconsistent results, highlighting the gap …

Rewriting Reality: The Sociological Context Of Gaslighting, Kristen L. Engasser Jr.

Honors Undergraduate Theses

In 2007, Robin Stern published The gaslight effect: How to spot and survive the hidden manipulation others use to control your life, highlighting gaslighting as a form of psychological abuse that makes victims question the validity of their perceptions. Since then, gaslighting has primarily been tackled from a psychological perspective. Some sociologists, however, theorize that gaslighting is not simply a psychological issue but a sociological one as well. They argue that gaslighting may take place unintentionally when a perpetrator acts on their biases towards members of other social groups, a concept known as epistemic gaslighting. As a form of …

Florida’S Most Recent Anti-Transgender Political Policies And Their Effects On Transgender Adults, Jaron A. Sanchez

Honors Undergraduate Theses

During May of 2023, Florida Governor Ron DeSantis signed multiple bills into law, which included House Bill 1521, Senate Bill 1580, and Senate Bill 254. Critics have regarded these bills to directly discriminate against transgender individuals and negatively impact their quality of life. The main research question this project seeks to answer is what impact these bills have, if any, on transgender individuals who live in the state of Florida. This includes experiences that negatively impact quality of life outcomes and mental health disparities. An online survey of a small sample of the population that self identifies as transgender, that …

This study explores the impact of homelessness on the identity formation of LGBTQ+ youth of color. This group of people is overrepresented within the unhoused community, and unfortunately, under-studied, especially within the qualitative data sector. A literature review found primary themes of identity formation, intersectionality, and discrimination and stigma. In addition to exploring the impact of housing instability on the identity formation of LGBTQ+ youth of color, this study emphasizes the significance of intersectionality in understanding their experiences. By noting the overlap of multiple marginalized identities such as race, sexual orientation, and gender identity, this research illuminates the unique challenges …

On The Rocks: The Association Between Dating And Alcohol Consumption Among Young Adults, Hannah Ettele

Honors Undergraduate Theses

Alcohol consumption is becoming an increasing concern among young adults. In 2018, approximately one-third of young adults in the United States reported binge drinking within the past month (Patrick et al., 2020). This peak in binge drinking during young adulthood raises concerns about physical and mental health. There are also societal implications of alcohol consumption, such as drunk driving, that are particularly evident among this age group (Stewart, 2023). As proposed by the Social Learning Theory (SLT) of alcohol use, there are many factors that motivate young adults to drink (Britton, 2004). Some engage in alcohol consumption to cope with …

Users must reveal certain pieces of information about themselves to benefit from the convenience of social media and the internet, such as allowing a website to access a specific location to find stores nearby. The problem arises when this data, particularly personal data, is misused. This dilemma of choosing which information to share is incredibly important as social media and the internet evolve. Taking control of one’s privacy may assist in determining which information to share and may reduce stress …

Examining The Effects Of Artemisia Annua On Neuro2a Cells, Wesley Lim

Honors Undergraduate Theses

Artemisia annua L. is a well-known medicinal herb used in Traditional Chinese Medicine for many centuries and contains artemisinin, which exhibits antimalarial properties [1] and is a potential treatment for SARS-CoV-2 [2]. However, the neurological effect of A. annua and its compounds are poorly understood. We hypothesize that A. annua extracts and artemisinin will provide protection against oxidative stress in mouse neuronal Neuro2A cells. Superoxide dismutase 1 (SOD1) is an anti-oxidant enzyme that protects against oxidative damage [3]. Growth Arrest and DNA Damage-inducible 45 alpha (Gadd45a) is involved in DNA repair and is a common biomarker for DNA damage[4]. SOD1 …

Curanderismo And Healing: Insights From Hispanic Young Adults, Allisa Castro

Honors Undergraduate Theses

Curanderismo is a holistic form of traditional medicine primarily used by Latin American populations and Hispanic communities in the United States. This type of care focuses on several aspects of health including physical, emotional and spiritual (supernatural). Hispanics are the largest ethnic minority population in the United States and yet healthcare access to this population remains limited by various barriers including lack of insurance, legal status, language, poverty, and other structural factors. Within this context, exploring the perceptions and role of traditional medicine, like curanderismo, as a form of healthcare becomes crucial in understanding and addressing the unique healthcare needs …

The Battle Over Diversity, Equity, And Inclusion And Critical Race Theory In Florida: A Case Study On The Stop W.O.K.E. Act, Grace Anne Castelin

Honors Undergraduate Theses

Accelerating from 2022 and continuing through 2024, the state of Florida has experienced significant policy changes, particularly within the realm of higher education and affairs of diversity, equity, and inclusion (DEI). Many progressive officials, experts, and activists assert arguments that the state is on the verge of evolving into an authoritarian regime while many illiberal policies are being produced through the Florida legislature and current executive leadership—social and economic sectors are consequently threatened in order to maintain political oppression. The Stop W.O.K.E. Act has served as a catalyst for shifting the state's political stance on DEI, culminating in a chain …

The Effects Of Nanobubbles For Gene Delivery For Osteoporosis Treatment, Abel Córdova Flores

Honors Undergraduate Theses

In recent years, the field of nanomedicine has provided promising alternatives to traditional ways of gene and drug delivery, such as nanobubbles instead of viral vectors. Manufacturing these nanomaterials is cost-effective and tends to be safer than previous forms of treatment for clinical use. In the realm of osteoporosis, a disease based around a higher rate of bone resorption to bone formation, leads to weak and brittle bones, leaving sufferers at risk for fractures, which are sudden and unexpected. These fractures are estimated to cost USD 22 Billion annually in the US alone. Reports show a significant effect on the …

Motivations For Retaliatory Aggression On Social Media Among Borderline Personality Endorsers, Hannah Grimes

Honors Undergraduate Theses

Social media has become a popular way of connecting with people, but it has also led to an increase in cyber aggression. Borderline Personality Disorder (BPD) is a condition that is characterized by retaliatory aggression, difficulty in interpersonal relationships, and high impulsivity. Those who endorse BPD symptoms experience unstable interpersonal relationships and struggle to maintain connections with others which can lead to problematic behaviors on social media like retaliatory aggression. Understanding the motivations behind those behaviors can help inform the experiences of the diagnosed population, mitigate problematic behaviors, and facilitate healthy social relationships. This study aims to explore the motivations …

Masculinity And Political Discourse: A Critical Analysis Of European Leaders, Taylor R. Haycock

Honors Undergraduate Theses

This project examines how European leaders of autocratic and democratic nations engage with masculinity discourses in their public speeches. Do authoritarian leaders use masculinity in a different way than democratic leaders? I answer this question by completing a critical discourse analysis of speeches from Vladimir Putin, Recep Tayyip Erdoğan, Boris Johnson, and Emmanuel Macron, the leaders of Russia, Turkey, the United Kingdom, and France, respectively. The speeches were publicized from July 2019 to September 2022, when all four leaders were simultaneously in office. I found that a similar rhetorical strategy focusing on dominance and strength was used across regime types …

How Super Pacs Supercharge Fundraising And Spending For Candidates In Presidential Primaries, Domenic Maglio

Honors Undergraduate Theses

The explosion of super PAC activity in presidential primaries since the 2012 election cycle prompts an examination of these organizations’ behavior and its effects on other types of committees. Specifically, this study investigates how fundraising and spending efforts by candidate-specific super PACs, or single-candidate super PACs, benefit their supported candidate’s principal campaign committee. Integrating data from the Federal Election Commission (FEC), Federal Communications Commission (FCC), and various qualitative sources, this study explores how candidate-specific super PACs are progressively exploiting their unique legal structure to fundraise for themselves and their candidate’s authorized committee. The probing reveals that candidate-specific super PACs steer …

Deceptive Realities: Exploring The Nexus Of Fake News, Artificial Intelligence, And Public Perception, Victor E. Milanes

Honors Undergraduate Theses

Our research delves into two critical areas: fake news and artificial intelligence (AI). Historically, fake news predates the printing press, but its resurgence after the 2016 US Presidential Election garnered mass attention. Studies indicate its potency, with one fake article found to be as influential as a campaign ad (Allcott & Gentzkow, 2017). However, partisan media likely skews its impact on public perception.

Conversely, AI's integration has surged in recent years, sparking both excitement and concern among the public (Pew Research Center, 2022). Its ability to generate hyper-specific images, demonstrated by DALL·E 2 and Midjourney, poses challenges in distinguishing real …

Latino Stereotypes In Hollywood: The Aesthetic, Artistic, And Art World Disobedience Of Mexican Cinema In America, Ashley J. Serrano

Honors Undergraduate Theses

In the spirit of Guillermo Del Toro, “Disobedience is a virtue” in life and acts as an essential element in the art of cinema, which allows filmmakers to tell stories about their nativism and imagination. With disobedience, it is a theme that allows filmmakers to resist and rebel against traditional methods of film production and storytelling found in mainstream Hollywood films while breaking barriers of the Cultivation Theory in which molds such Latino stereotypes through the way the media paint the landscape of society. American cinema has utilized stereotypical Latino characters portraying Cholos, occasional sex symbols, indolent labor workers, illiterate …

The Relationship Between Creative Activity And Physiological Symptoms Of Anxiety, Amanda G. Solivan
