Development Of A Customizable Framework For Data Driven Hemodynamic Analysis With Applications In Neurovascular And Cardiovascular Scenarios, Rachel Mae Hillner
Development Of A Customizable Framework For Data Driven Hemodynamic Analysis With Applications In Neurovascular And Cardiovascular Scenarios, Rachel Mae Hillner
Theses and Dissertations
Cardiovascular disease, including but not limited to heart failure and aneurysms, remain a leading cause of death worldwide. Persons over the age of 40 experience upwards of a 20% chance of developing heart failure in their lifetime. With a decrease in viable donor hearts, the reliance on mechanical heart assist devices is on the rise. However, such devices are not without their complications. Specifically, for left heart failure, a common treat, the left ventricular assist device, is characterized by clotting, stroke, and low survival rates as a result. Many studies suggest that such unfavorable results are correlated to adverse hemodynamic …
A Reduced Order Model For Estimation Of Fractional Flow Reserve (Ffr) In Coronary Artery Disease: Assessing The Impact Of Side Branches, Arber Vila
Theses and Dissertations
Coronary Artery Disease (CAD) affects millions of people worldwide and remains a leading cause of morbidity and mortality. To effectively plan treatment and risk stratification, assessing CAD severity is of paramount importance. Fractional flow reserve (FFR) is a critical clinical parameter used to evaluate CAD severity, measured by the ratio of mean distal coronary pressure to mean aortic pressure during hyperemic conditions. Although non-invasive FFR estimation methods have gained popularity, computational fluid dynamics (CFD) is impractical for routine clinical use due to the time and resources required. To address this issue, a reduced order model is proposed that accurately captures …

Chop Suey Habits: The State Of The American Chinese Restaurant During Covid Times, Rebecca Ma
Theses and Dissertations
With the outbreak of COVID-19 in Spring 2020, the yellow peril has come back from its clandestine hiding spot with attention directed towards East and Southeast Asian citizens. In the ongoing debate of cleanliness and sanitization during a pandemic, the yellow peril scare has once again American Chinese restaurants. American Chinese restaurants found themselves to be the target of online abuse and loss of patronage in these uncertain times. While over half of American Chinese restaurants took the loss and shut down in March/April 2020, they still reopened to partial to full capacity sometime in 2020. American Chinese restaurant owners …
Developing Weak Galerkin Finite Element Methods, Ahmed Sallal Joudah Al-Taweel
Developing Weak Galerkin Finite Element Methods, Ahmed Sallal Joudah Al-Taweel
Theses and Dissertations
The weak Galerkin finite element method is a flexible and effective numerical technique for solving partial differential equations (PDEs). The goal of this dissertation is to develop new weak Galerkin schemes for solving PDEs on uniform triangular partitions in 2D. These schemes will improve the efficiency of the weak Galerkin method and avoiding numerical locking. First, we investigate the lowest-order weak Galerkin finite element method for solving reaction-diffusion equations with singular perturbations. Then, we propose a weak Galerkin method for the Laplace equation using harmonic polynomial finite elements instead of the full polynomial space $P_k$ to achieve the same order …
Understanding Groundwater Flow In A Saturated Buffer Zone ( Sbz ) Using Numerical Models: Case Study Of T 3 Site, Mclean County, Central Illinois, Nnaemeka Henry Nsude
Understanding Groundwater Flow In A Saturated Buffer Zone ( Sbz ) Using Numerical Models: Case Study Of T 3 Site, Mclean County, Central Illinois, Nnaemeka Henry Nsude
Theses and Dissertations
Loss of nutrients, such as nitrogen and phosphorous, from agricultural lands in the Midwest affects farm productivity and environmental quality. Nutrient runoff from lands discharged into streams degrades the aquatic ecosystem through eutrophication and subsequent hypoxic conditions. The presence of nitrogen also threatens the potability of numerous aquifer bodies globally due to their high solubility in water. To tackle this problem, best management practices such as Saturated Buffer Zone (SBZ) are implemented to reduce nitrogen from nitrate-laden tile water from agricultural lands before being discharged into streams. Groundwater flow and interactions at SBZ are not well understood. To aid the …
Physiognomy And Emotional Abuse In Elizabeth Gaskell's "The Grey Woman", Natalie Ann Davis
Physiognomy And Emotional Abuse In Elizabeth Gaskell's "The Grey Woman", Natalie Ann Davis
Theses and Dissertations
Perrault's Bluebeard tale is a story of domestic abuse: Bluebeard tries to control his wife's movements by prohibiting her from entering a specific room in their chateau and attempts to kill his wife as punishment when she ultimately disobeys him. Bluebeard's violence towards his wife clearly marks him as an abuser. There have been countless other versions of the Bluebeard tale including Elizabeth Gaskell's short story "The Grey Woman." Unlike other versions of the tale that emphasize Bluebeard's physically abusive behavior, Gaskell's version focuses on a more subtle form of abuse: emotional abuse. Emotional abuse has remained an obscure topic …
Toxicity And Reddit: A Study Of Harmful Effects On User Engagement And Community Health, Nahiyan Bin Noor
Toxicity And Reddit: A Study Of Harmful Effects On User Engagement And Community Health, Nahiyan Bin Noor
Theses and Dissertations
The rise of social media has led to an alarming increase in harmful content, including abusive language, disrespect, and hate speech. While social media platforms have attempted to address this issue, harmful content cannot be completely eradicated before it impacts individuals or communities. In this thesis, we conduct a comparative analysis of toxicity on three social media platforms: Twitter, Parler, and Reddit. Using Reddit data, our study employs a tree structure to visualize and divide each conversation thread, allowing for an in-depth examination of the impact of toxic content on communities. We also used different machine learning algorithms to classify …

Theses and Dissertations
The purpose of this sequential exploratory study was to investigate how New Jersey public high school coaches who self-report transformational leadership traits may potentially influence the development of civic mindedness in their respective student-athletes. Three main research questions were posed regarding coaches’ transformational leadership practices, their roles in the development of students’ civic mindedness, and connections between the two. It was posited that the behavior of coaches can have a significant effect on the student-athletes that participate on their teams. The theoretical lens of transformational leadership permeates this research. A mixed-methods approach was utilized. Kouzes and Posner’s Leadership Practices Inventory …
Mapping Psychological Safety In The Nursing Classroom: A Situational Analysis, Lori Beth Beard
Mapping Psychological Safety In The Nursing Classroom: A Situational Analysis, Lori Beth Beard
Theses and Dissertations
The purpose of the qualitative situational analysis was to explore the interconnectedness of human and non-human elements that shape psychological safety in the associate degree nursing classroom learning environment. Using grounded theory methods together with situational analysis, specifically situational mapping, a theory of psychological safety in the nursing classroom emerged from the data. The data highlighted several theoretical categories that capture how faculty use various elements to construct psychological safety in the classroom. From the data emerged the theory that nurse faculty connect their nurse identities to the elements when building psychological safety into the classroom learning environment. Implications for …

Assessing The Role Of Hybridization In The Evolution Of Two Common Lineages Of Lichen-Forming Fungi, Rachel Keuler
Assessing The Role Of Hybridization In The Evolution Of Two Common Lineages Of Lichen-Forming Fungi, Rachel Keuler
Theses and Dissertations
Once thought to be an evolutionary dead-end, hybridization is now being detected in genomes across kingdoms, perhaps even playing an integral role in evolution. In chapter 1, I investigated the potential influences of hybridization on the evolution of a group of vagrant, asexual species in the Rhizoplaca melanophthalma species group. I sequenced the mitochondrial and nuclear genomes of 55 specimens and found well-supported nuclear phylogenies of both datasets. There were, however, multiple instances of discordance between the mitochondrial and nuclear trees, which can be caused by hybridization. PhyloNet and ABBA-BABA also detected widespread hybridization among this group. In chapter 2, …
"Very Beautiful And Very American": A Multicultural Analysis Of Florence B. Price's Quintet In A Minor For Piano And Strings, Taryn Jane Carvajal Harding
"Very Beautiful And Very American": A Multicultural Analysis Of Florence B. Price's Quintet In A Minor For Piano And Strings, Taryn Jane Carvajal Harding
Theses and Dissertations
This paper examines the Quintet in A Minor for Piano and Strings by Florence B. Price (1887-1953). One of Price's latest compositions (with final revisions dated January 21, 1952), the Quintet is a masterful example of what is possible when using a multicultural lens to approach the making of American music. This paper exposes the insufficiency of examining (and assessing) multicultural composers and their works only with traditional Western European analytical views, when an expanded approach is needed to explain many of the non-European musical influences and phenomena. While more complex and challenging, this expanded analytical approach sheds added light …
Popr: Probabilistic Offline Policy Ranking With Expert Data, Trevor F. Schwantes
Popr: Probabilistic Offline Policy Ranking With Expert Data, Trevor F. Schwantes
Theses and Dissertations
While existing off-policy evaluation (OPE) methods typically estimate the value of a policy, in real-world applications, OPE is often used to compare and rank policies before deploying them in the real world. This is also known as the offline policy ranking problem. While one can rank the policies based on point estimates from OPE, it is beneficial to estimate the full distribution of outcomes for policy ranking and selection. This paper introduces Probabilistic Offline Policy Ranking that works with expert trajectories. It introduces rigorous statistical inference capabilities to offline evaluation, which facilitates probabilistic comparisons of candidate policies before they are …
Superabsorbent Polymer Use In Rangeland Restoration, Shannon V. Nelson
Superabsorbent Polymer Use In Rangeland Restoration, Shannon V. Nelson
Theses and Dissertations
Soil moisture deficits often hinder rangeland revegetation efforts. Due to sheer numbers and germination timing, invasive annual species can easily outcompete those of desired seeded species for resources, including water. One way to increase seedling establishment may be to increase the amount of water available to seeded species. Superabsorbent polymers (SAPs) can absorb and release hundreds of times their weight in water and slowly release it. Concentrated SAP bands at or near seedling rooting depth may act as a soil water reservoir for germinating seedlings and increase rangeland seedling establishment. The objective of these studies was to evaluate the effect …
A Longitudinal Look: How Sleep Impacts Suicidal Thoughts And Behaviors In Autism And Social Anxiety, Lindsay Jacalyn Regehr
A Longitudinal Look: How Sleep Impacts Suicidal Thoughts And Behaviors In Autism And Social Anxiety, Lindsay Jacalyn Regehr
Theses and Dissertations
Crucial research about suicidal thoughts and behaviors is often done in a cross-sectional manner that only considers limited risk factors. This research is limited in scope and rarely produces meaningful results to inform treatment. This study uses a longitudinal design to follow 93 participants over approximately 6 months. Participants are individuals with autism and social anxiety who were part of high-risk groups for suicidality, sleep problems, and social isolation. Participants recorded their sleep patterns and suicidal thoughts daily via the phone app MetricWire and continuously wore a GENEActiv actigraphy device to tract their objective sleep patterns. The Columbia Suicide Severity …
Social Media's Impact On The Puerto Rican Diaspora After Hurricane Maria, Heidi Lynn Steidel Ii Camacho
Social Media's Impact On The Puerto Rican Diaspora After Hurricane Maria, Heidi Lynn Steidel Ii Camacho
Theses and Dissertations
Puerto Rico has belonged to the United States for more than a century. In 1898, more than two decades after the Spanish American War, Spain formally ceded the island to the United States. Just over 20 years later, islanders officially became American citizens. Since then, the 100-mile-long by 35-mile-wide island has experienced economic and political crises, the COVID-19 pandemic, and life-threatening natural disasters. These events provoked a vast fluctuation in its population. After Hurricane Maria unfolded in September 2017, more than 200,000 Puerto Ricans moved to the continental United States to start new lives (Schwartz, 2018). This qualitative study sheds …
Semantic Overflow Of Powerful Feelings: Digital Humanities Approaches And The 1805 And 1850 Versions Of Wordsworth's Prelude, Dylan Hansen
Semantic Overflow Of Powerful Feelings: Digital Humanities Approaches And The 1805 And 1850 Versions Of Wordsworth's Prelude, Dylan Hansen
Theses and Dissertations
Scholars have repeatedly contrasted the 1805 and 1850 versions of William Wordsworth’s The Prelude since the discovery and publication of the former by Ernest De Sélincourt in 1926. Points of contention have included the 1850 poem’s grammatical revisions and shifts toward greater political and religious orthodoxy. While these discussions have waned in recent decades, digital humanities tools allow us to revisit oft-debated texts through new lenses. Wanting to examine scholarly claims about The Prelude from a digital humanities perspective, I collaborated with Dr. Billy Hall to enter both versions of the poem into a data analysis and visualization tool, which …
An Acoustic Description And Synchronic Comparison Of Morphological Reduplication In Hiligaynon, Nathan W. Adamson
An Acoustic Description And Synchronic Comparison Of Morphological Reduplication In Hiligaynon, Nathan W. Adamson
Theses and Dissertations
This thesis is an acoustic analysis, grammatical description, and typological comparison of morphological reduplication in Hiligaynon, an Austronesian language spoken in the Western Visayas region of the Philippines. This work has two main goals: first, to redescribe the formal and functional properties of full reduplication in Hiligaynon; and second, to offer a typological analysis as to how the system of reduplication in Hiligaynon compares to the known typological universals of human language, and within the genetically related languages of the Philippines. While reduplication in Hiligaynon has previously been described (Wolfenden 1971; Cameron 1985; Zack 1994; Spitz 2001; Santos 2012), the …
The Morpheme -Ga In Pastaza Quichua, Charles W. Alger
The Morpheme -Ga In Pastaza Quichua, Charles W. Alger
Theses and Dissertations
Pastaza Quichua (PQ) is a member of the Quechua IIB branch of Quechuan languages and has a rich morphology. However, this richness is often over-simplified for the sake of simpler explanation. Most Quechuan languages have a morpheme that is usually spelt -ga, -ka or -qa, and is described as a topicalizing clitic. In this thesis, I will examine the morpheme -ga in PQ, which, like its cognates, is often said to be a topicalizing clitic, despite the fact that it frequently breaks traditional rules for both topic marking and clitic-hood. I find that -ga is a topic marker according to …
A Survey Analysis Of United States Community College Esl Programs, Haley Mckee Hanson
A Survey Analysis Of United States Community College Esl Programs, Haley Mckee Hanson
Theses and Dissertations
English learners (ELs) across the United States have aspirations to continue their education and pursue careers in the English language. Because community colleges are educational institutions that not only generally provide open enrollment but are also more accessible and affordable than universities, they are a feasible option for many ELs. Community colleges often have an English as a Second Language (ESL) program available to ELs to help them reach the proficiency needed to study in the English language. This study explores how these programs are structured, who is administering and teaching in these programs, and if these programs track their …
The Effect Of Musical Training On Second Language Grammar Acquisition, Deven Joseph Hunsaker
The Effect Of Musical Training On Second Language Grammar Acquisition, Deven Joseph Hunsaker
Theses and Dissertations
Music's effect on non-musical domains has been an area of intense research. Musical training has been shown to positively affect the processing of phonology, lexical tone, and syntax. While music also has positive effects in second language phonology acquisition, its effect on grammar acquisition is contested. This thesis aimed to study the under-researched topic of music and second language grammar acquisition using electroencephalography (EEG), thereby studying the electrical responses of the brain. Beginning level Spanish students were trained on a new grammatical principle prior to performing a grammaticality judgment task, and their behavioral and neural results were analyzed. Those students …

Theses and Dissertations
This study examined the Voice onset time (VOT) of Mandarin and English initial position stops as produced by native American-English speaking learners of Mandarin and also native speakers. The study primarily investigated the role of second language experience on native-like production of L2 VOT for the Mandarin stops /p, t, k, ph, th, kh/ and additionally examined any evidence for phonetic drift in the L1 English VOT as a result of L2 Mandarin learning and acquisition. To achieve this, the production of L2 Mandarin and L1 English by native AmericanEnglish speaking learners of Mandarin of two different levels of experience …
Non-Fatal Strangulation During Sexual Assault: A Retrospective Review, Brooke E. Stacey
Non-Fatal Strangulation During Sexual Assault: A Retrospective Review, Brooke E. Stacey
Theses and Dissertations
Background: Non-fatal strangulation (NFS) is a life-threatening event in cases of sexual assault. The incidence of NFS during sexual assault is increasing on a global scale. NFS is a gendered crime as most victims are women and most assailants are men and is more common in intimate partner violence. Strangulation victims only have visible neck injuries around 50% of the time, but visible injuries are not a reliable indicator of the severity of the assault. NFS can cause neurological damage from lack of blood flow to the brain and result in physical and psychological trauma. NFS indicates a high degree …
On And On And On, Rachel Hansen
On And On And On, Rachel Hansen
Theses and Dissertations
One defining root of the essay is its goal to articulate thoughts, simple and complex, into a piece that readers might deliberate and rest and even rely on. On this or that or the other-- "on" being a word suggesting sturdiness and foundation. On and On and On is a collection of personal essays which intends to examine the theories of "truth" (another word associated with sturdiness,) within personal experiences, as they are delivered through creative means. When truths in life are examined and explored in essayistic ways, we discover more profound axioms of the soul that would otherwise remain …
