Automated Conjecturing On The Independence Number And Minimum Degree Of Diameter-2-Critical Graphs, Joshua R. Forkin

Theses and Dissertations

A diameter-2-critical (D2C) graph is a graph with diameter two such that removing any edge increases the diameter or disconnects the graph. In this paper, we look at other lesser-studied properties of D2C graphs, focusing mainly on their independence number and minimum degree. We show that there exist D2C graphs with minimum degree strictly larger than their independence number, and that this gap can be arbitrarily large. We also exhibit D2C graphs with maximum number of common neighbors strictly greater than their independence number, and that this gap can be arbitrarily large. Furthermore, we exhibit a D2C graph whose number …

Challenges Among Latine Daca Recipients And Anxiety: A Systematic Meta-Analytic Review, Isis A. Garcia-Rodriguez

Theses and Dissertations

Immigrant-origin Latine young adults (ILYAs) face a challenge that is specific to their developmental period. As ILYAs transition from high school to beyond (e.g., workforce, college, etc.), they begin to grapple with participating in normative experiences for all young adults in the U.S. (e.g., obtaining a driver’s license, getting their first job at 16). The lives of ILYA, particularly those who are DACAmented or DACA eligible, are characterized by the legal and social contradiction that arises from growing up in the U.S. yet facing barriers to full participation in U.S. society. The nonexistent synthesis of the exponentially growing literature in …

Madeleine Béjart: La Femme Galante, Katherine E. Jackson

Theses and Dissertations

The 17th Century marked the beginning of women professionally joining the acting profession and as such brought about change in the career opportunities for women. Madeleine Béjart was one of these actresses who is notorious for her liaison and working relationship with famed playwright, Molière. Through this personal relationship her role in history was relegated to that of mistress and the scandal concerning Molière’s wife Armande who is speculated to either be Madeleine's daughter or sister. By using historical and biographical information on Madeleine along with two works of Molière in which she originated roles, I will explore the intricacies …

Threshold Levels Of Patient And Parent Esthetic Concern In The Mixed Dentition, Justin Josell

Theses and Dissertations

Purpose: The mixed dentition is a period of unique dental changes for developing children and their parents.

Taking Flight: An Independent Living Facility For Emancipated Foster Youth, Kristy Mcdaniel Leitzel

Theses and Dissertations

Motivation

Many of us think about foster care in the context of younger children removed from home. However, little thought is given to youth that age out of the foster care system and the associated challenges and risks they face, namely in the area of housing.

Youth in foster care often receive minimal support in making the transition to independence and are frequently forced into instant adulthood. They are faced with an abrupt end of support at a time when they have not yet mastered the educational, social, or economic survival skills necessary to be independent in the community (Haas, …

Periodic Trends In The Infrared And Optical Absorption Spectra Of Metal Chalcogenide Clusters, Alain Ward

Theses and Dissertations

We have investigated the Optical absorption, Infrared spectra, Binding Energies, and various other cluster properties to determine the existence of periodic trend for Transition Metal Chalcogenide Clusters ligated with CO ligands. We were motivated to answer the question of whether periodic behavior can be observed in properties of octahedral metal-chalcogenide clusters. We have used the Amsterdam Density Functional code to calculate the electronic structure of Transition Metal Chalcogenide Clusters using gradient-corrected density functional theory. We determined the existence of several periodic trends in properties of octahedral Transition Metal Chalcogenide Clusters TM₆Se₈(CO)₆. To investigate these …

Connections Exposed | A Library For The People, Stephanie Wilburn

Theses and Dissertations

MOTIVATION

The U.S. economy, democracy, and the health and happiness of citizens depends on maintaining social capital, the networks of bonds between community members. Social capital creates the trust that facilitates action and cooperation for mutual benefit. Since the 1960s, there has been a decline in-person socialization and social bonds both within and between demographic groups in the US resulting in reduced social capital (Putnam, 2000).

One measure to combat declining social capital is to create third places where incidental and repeated social interactions build and reinforce bonds between community members (Oldenburg, 1997).

With the reduction of accessible and inclusive …

Sociodemographic And Injury Severity Characteristics As Predictors Of Functional Independence In Older Adults With Tbi Up To 10 Years Post Injury, Carmen M. Tyler

Theses and Dissertations

Traumatic brain injury (TBI) incidence rates have been increasing in recent years, with the greatest number of TBIs and the highest morbidity and mortality rates in individuals aged 80 and over. As average life expectancy continues to increase, the older adult population is expected to comprise nearly one-quarter of the U.S. populace by 2060. With the increased risk to a larger proportion of the U.S. population posed by TBI, the aim of the current study was to examine the roles of sociodemographic and injury severity characteristics as predictors of functional independence trajectories across 1, 2, 5, and 10 years after …

Considering Queerness - Actor Training's Issues And Alternatives, Jacob Leblanc

Theses and Dissertations

Educators in academic theatre programs, whether queer or non-queer, trans or cisgender, may not intentionally consider queerness in their pedagogical practices. What follows is an examination of current issues in academia that can affect queer students negatively and disproportionately. Anecdotal evidence is provided to demonstrate different issues that may be present in the classroom experiences of queer students. The Stanislavski system is critiqued through a contemporary, queer lens to locate possible shortcomings in the acting technique when it is applied by queer performers. Queer alternatives to the Stanislavski system are vetted and offered to queer students who might seek something …

The Economic Value Of Pharmacist-Physician Collaborative Care Models In Hypertension Management, Jessica S. Jay

Theses and Dissertations

Background: Hypertension is highly prevalent in the United States, affecting nearly half of all adults (43%). Studies have shown that pharmacy-physician collaborative care models (PPCCM) for hypertension management significantly improve blood pressure (BP) control rates and provide consistent control of BP. Time in target range (TTR) for systolic BP is a novel measure of BP control consistency that is independently associated with decreased cardiovascular (CV) risk. There is no evidence observed improvement in TTR for systolic BP with PPCCM is cost effective.

Objective: This study aimed to compare the cost-effectiveness of PPCCM with usual care for the management of hypertension …

Shackled: To A Front-Row Seat Of My Own Horror Film, Dellil L. Mohammed

Theses and Dissertations

This document serves as internal view point, stemming from my experiences as a black muslim, first generation Ethiopian American, overall identity, and it’s disorienting implication on my interpretation of my view-self and the world. This is also informed by my struggling with the realities of type-1 diabetes and the sporadic and often inadequate support of the American health system. All of these intersecting experiences have led to me making work as an agent for advocacy, empathy and social justice. This work is also informed and dressed with the elements of horror, sci-fi, & fantasy. See and hear the voice in …

Characterizing Senescence Induction And Senolytic Sensitivity In Murine Lung Cancer Cell Lines, Rana A. Estaleen

Theses and Dissertations

While cancer patients often experience tumor reduction after receiving chemotherapy, tumors can eventually emerge from a state of dormancy. Cancer cells treated with the topoisomerase II poison, etoposide (ETO), enter senescence, which is a durable and prolonged cell cycle growth arrest. Different murine lung cell lines were screened for their levels of senescence induction by ETO, and those showed promising senescence induction were then treated with the senolytic, ABT263, to promote apoptosis. The hypothesis of this work was that non-small cell lung cancer cell lines will have different degrees of senescence and that the magnitude of the response to senolytics …

Incorporating Ontological Information In Biomedical Entity Linking Of Phrases In Clinical Text, Evan French

Theses and Dissertations

Biomedical Entity Linking (BEL) is the task of mapping spans of text within biomedical documents to normalized, unique identifiers within an ontology. Translational application of BEL on clinical notes has enormous potential for augmenting discretely captured data in electronic health records, but the existing paradigm for evaluating BEL systems developed in academia is not well aligned with real-world use cases. In this work, we demonstrate a proof of concept for incorporating ontological similarity into the training and evaluation of BEL systems to begin to rectify this misalignment. This thesis has two primary components: 1) a comprehensive literature review and 2) …

Using Individual Determinants To Predict Behavioral Health Service Use In Integrated Pediatric Primary Care, Alfonso L. Floyd Jr.

Theses and Dissertations

Mental health problems (e.g., attention, externalizing, internalizing) are commonly observed in youth and are often associated with significant impairment and an increased need for mental health services. Conceptual frameworks, such as Andersen’s Behavioral Model of Health Service Utilization, have proposed that several individual determinants (e.g., predisposing, enabling, and need factors) may influence service use for mental health problems among youth. Despite the glaring need for mental health treatment among youth with mental health problems, studies indicate that many affected youths do not receive mental health care. Integrated pediatric primary care (IPPC) settings provide an ideal setting for youth and families …

Towards The Systematic Evaluation Of Variable Modes Of Mechanical Conditioning On The Compositional, Microstructural And Mechanical Properties Of Engineered Tissue Vascular Grafts., Sarah Saunders

Theses and Dissertations

Coronary artery bypass surgery (CABG) remains one of the most common cardiac surgical procedures performed worldwide, frequently involving multiple bypasses, and commonly employing the patient’s internal mammary artery, radial artery, or saphenous vein. CABG is often not possible because native vessels were already employed in previous interventions or are diseased themselves. Synthetic vascular grafts are currently integral tools of vascular surgery and have had relative success in large-caliber applications providing substantial benefit to aortic or iliac grafting; however, small diameter (< 6 mm) arterial grafts have not yet translated into clinical effectiveness due to thrombosis and anastomotic intimal hyperplasia. ETVGs present an exciting potential alternative in vascular grafting by offering a blood vessel substitute that could exhibit all the functional characteristics of native vasculature. In addition to relieving supply limitations associated with coronary artery bypass surgery ETVGs are especially ideal for pediatric patients with congenital heart disease who require grafts that grow as they do, eliminating the need for reoccurring invasive surgeries.

Though the role of biomechanics in regulating cellular behavior promoting non-thrombogenicity, vasoactivity, and ECM synthesis and maintenance is well …

Examining Ayahuasca Constituents At 5-Ht2a Receptors In Search Of Antidepressant Action, Jeremy D. Rolquin

Theses and Dissertations

Recently, it has been reported that ligands of the 5-HT_2A receptor can have drastic and fast-acting efficacy towards a number of different mental health disorders, such as depression and anxiety. A mixture of Amazonian plants calledayahuasca contains multiple compounds which have been shown to interact with the serotonergic system, and the 5-HT_2Areceptor in particular.

The structurally similar compounds (DMT, harmine, harmaline, and tetrahydroharmine) found in ayahuasca were examined for differences in their physiochemical properties that might contribute to their binding affinity for the 5-HT_2Areceptor. 3D Molecular modeling and docking studies of these compounds were …

Theses and Dissertations

Respiratory distress syndrome (RDS) is characterized by shortness of breath and low oxygen levels. RDS affects the neonatal and adult populations. In the neonatal population, RDS can be classified as NRDS (Neonatal respiratory distress syndrome), while in adults, it is known as ARDS (acute respiratory distress syndrome). This dissertation examines a therapeutic approach to NRDS and a mechanistic approach to ARDS with in vivo and in vitro models of lung injury. NRDS is characterized by a deficiency or lack of surfactant. Surfactant is an essential compound composed of phospholipids and proteins to prevent the lungs from collapsing. There are several …

The Examination Of Health Care System Distrust As A Barrier To Utilization And Engagement Of Preventive Services In The Health Care System In Black Emerging Adults, With A Special Focus On Insurance Status And Usual Source Of Care., Alexandra Wynn

Theses and Dissertations

Health care system distrust is a well-known barrier to health utilization and engagement in older African Americans. However, it has not been explored in Black emerging adults, individuals 18- 26. It is important to explore the social and psychological effects of systemic barriers, such as health care system distrust, in this developmental period as emerging adults undergo unique demographic shifts, changes in sense of self, and identity exploration. Due to emerging adulthood being an exploratory and challenging transitionary phase, emerging adults have an increased susceptibility to preventable morbidity and mortality issues and decreased access to important preventive services. Thus, health …
