Lucia Colombari
"Italian Futurism and American Modernism: Exhibition Practices, Collecting, and Transnationalism (1909-1929)" critically examines the role of international exhibitions in the reception, dissemination, and transformation of Italian Futurism in the United States during the first decades of the twentieth century. It reframes what constituted Futurism beyond its national borders and demonstrates how four influential exhibits informed the diverse configurations of the movement across the Atlantic. The reception of Futurism in the United States was a multi-layered...

Nurses as Formal Leaders in United States Civilian Hospitals: 1891-1991

Joel Anderson
Nursing leadership has evolved since the 1890s and has taken different forms throughout nursing history for the sake of preserving the nursing profession against the headwinds of competing medical and hospital administrator professions. Through the examination of the professional lives of Isabel Hampton Robb, Belva Overton, Sister Mary Maurita Sengelaub, and Anne Zimmerman, the evidence demonstrates that nursing leaders adapted to internal (hospitals and health systems) and external (insurance reimbursements) factors. Starting with the initial...

Heterogeneous Heparin Presentation in Microporous Annealed Particle (MAP) Hydrogel for Accelerated Biomaterial-Tissue Integration

Lauren Pruett
Regenerative biomaterials seek to restore function and structure to a damaged tissue; however, translation of regenerative biomaterials into the clinic has been limited by negative foreign body responses that restrict tissue ingrowth. Avoiding a foreign body response while promoting active tissue ingrowth could be the foundational features needed to enable biomaterial clinical translation. Recently, a new class of biomaterial called microporous annealed particle (MAP) hydrogel has shown great promise for clinical translation as it avoids...

Exploring Role Identity and Resistance as a Complex System amongst Doctoral and Undergraduate STEM Students

Anne McAlister
STEM students assume many roles, including engineer, researcher, educator, and student, through which multiple role identities may form. When social expectations of roles become internalized, they become role identities. Role identities, especially engineering or science identity, relate to persistence and belonging in STEM. Roles that students take on can represent the culture of the institution and academia at large; thus, understanding academic role identity and how institutional norms may influence role identity is important in...

Exploring the Role of Maternal Cognitions, Parenting Practices and Neighborhood Opportunities in Preschoolers' Development

Deiby Mayaris Cubides Mateus
The three papers that comprise this dissertation analyze paths through which family, neighborhood resources, and parenting interventions influence preschoolers’ development. Paper 1 examined the extent to which parenting practices and home environment changed between pre-kindergarten entry and kindergarten entry, and whether these aspects of parenting were related to children’s school readiness. Paper 2 explored whether neighborhood resources moderated the relationship between family cumulative risk and the growth trajectory of children’s executive function skills. Finally, paper...

Moving the Dialogue Forward: Virtual Student Conversational Agent Design in Low Data Environments

Maria Phillips
Tech giants have spent millions of dollars developing what appear to be intelligent conversational agents, such as Siri and Alexa. While advancing portions of the text analytics field, these applications often rely on vast amounts of pre-programmed tasks and rules-based dialogue policies, as well as a large amount of domain expert input to achieve the illusion of language understanding. The illusions created by either well-funded or straight-forward, closed-domain, task-oriented, and typically customer-service-centric conversational agents have...

Computational Models of Engagement in Digital Health Platforms

Sonia Baee
Over the past decade, digital health technologies have transformed healthcare delivery offering more scalable, accessible, and individualized interventions. Especially in light of the COVID pandemic, these technologies are an appealing alternative to much-needed treatment outside the physician/clinician’s office. However, these platforms suffer from low engagement and high attrition rates, making it increasingly difficult to turn research findings into clinically useful and actionable insights. This dissertation proposes a set of computational tools for both predicting participants'...

Investigation of Primary Process Parameters for Laser Powder Bed Fusion of High Temperature Alloys through Physical and Virtual Experimentation

Adrian Dalagan
Recent innovations in the aerospace and energy industries require materials capable of maintaining sufficient mechanical strength at high operating temperatures. A category of materials that possesses these capabilities are refractory metals. However, due to several factors, such as their very high strength at room temperature, they are difficult to shape through conventional metal removal manufacturing practices. Because of this, additive manufacturing methods, such as laser powder bed fusion are being explored for cost-effective fabrication of...

High-Speed Photodiodes for Applications in Photonic-Based Millimeter Wave Systems

Jesse Morgan
Technologies based on millimeter wave (mmWave) (30-300 GHz) systems continue to emerge in the areas of wireless communications, radar, imaging, and spectroscopy. While exact requirements vary between applications, a fundamental requirement exists for all photonic-based platforms: mmWave sources capable of high-frequency, high-power operation and, ideally, wide tunability. To achieve mmWave operation in photonic-based approaches, photodiodes (PDs) with broad bandwidth (DC to 100’s of GHz) and high-power capability play a critical role in converting optical signals...

Genetically Encoded Far-Red Fluorescent Zn2+ and Ca2+ Indicators

Tianchen Wu
The color palette of genetically encoded fluorescent protein indicators has expanded rapidly in recent years. Genetically encoded indicators with excitation and emission within the “optical window” above 600 nm are expected to be superior in many aspects, such as enhanced tissue penetration, reduced autofluorescence and scattering, and lower phototoxicity. We first explored the tolerance of two far-red fluorescent proteins (FPs), mMaroon1 and mCarmine, towards circular permutation. Five circularly permuted far-red FPs (cpFrFPs) with excitation and...

Using Corn Ethanol to Slow Climate Change

William Mosberg
With each passing year climate change is becoming harder and harder to ignore, with more activists, celebrities, politicians, and others speaking up about the issue. This thesis serves two goals. The first to discover how even with a large amount of evidence supporting the theory of climate change, the American public has been very reluctant to fully embrace renewable energy. The second is to provide another opportunity to reduce the global carbon footprint through the...

DARA: Development of a Chatbot Support System for an Anxiety Reduction Digital Intervention; Using Actor Network Theory to Analyze Digital Mental Health Interventions for Individuals of Low Socioeconomic Status

Annabel Lynch
The prevalence of mental health conditions, such as anxiety and depression, has increased in the US in recent decades. Unfortunately, only about half of the US population suffering from these conditions will receive treatment. With this level of burden, treating people one-on-one in a traditional clinical setting will never meet the existing needs of mental illness intervention. People of low socioeconomic status (SES) are more likely to suffer from mental illness, as well as less...

Elizabeth Wood
Despite the millions of dollars allocated to medical research annually, many major gaps still exist in the field of biomedical research. My capstone team aimed to develop a solution for a major shortcoming in the field of cancer research, and I aimed to address the lack of female representation in research in my technical thesis. Cancer remains one of the leading causes of deaths across the globe, despite worldwide efforts to research cancer biology and...

Covid-19 in Native America

Brianna Baldwin
According to CDC data, American Indians, and Alaskan Natives (AI/AN) have insofar experienced the highest rates of COVID-19 cases, hospitalizations, and deaths among any ethnic group in the U.S., despite the highest rate of vaccinations among any ethnic group. AI/AN peoples suffer 1.7x cases, 3.5x hospitalizations, and 2.4x deaths when compared to White, Non-Hispanic persons. In June 2020 in particular, the Navajo Nation reported a 3.4% COVID-19 infection rate, higher than any U.S. state. The...

Smart Pet Feeding Station; The Motivations of Smart Home Technology Adoption

Matthew Garrison
The STS and technical projects were both largely inspired by experiences from the UVA Computer Engineering Program. The technical project, an automatic pet feeding station, was decided on out of a love for pets, and also because it was a very hands-on application of the computer engineering disciplines and skills that the team had developed over the previous three years. Meanwhile, the STS Research topic, of smart home devices, came from the fact that the...

URM equals Black, Hispanic, or Native Hawaiian/Pacific Islander. Multivariable analysis included URM status, gender, years of practice, and Doximity institution rank. Results: Among 1,644 residents, 145 (9%) were URMs, with a median of 2 (IQR 1,5) pubs for URMs and...

Pulse Wave Analysis for Cardiovascular Disease

Lauren Orr
Pulse wave analysis (PWA) is a technique that studies the shape of a pressure waveform caused by a heartbeat in order to estimate cardiovascular health. The waveform is often measured from the aorta, where the morphology is well understood in relation to cardiovascular physiology, but the waveform can also be measured from the peripheral circulation with a pulse oximeter, via photoplesmography. Thus, the goal of this project was to create a noninvasive diagnostic device that...

Usability of a Video Support Tool to Elicit Patient Preferences in a Medical ICU

Kirsten Mccavanagh
Significance: The state of the science of Advance Care Planning in the acute or critical care setting urges care givers to elicite patients’ goals as the standard of care. (Kelley & Morrison, 2015; Kavalieratos et al., 2016; Center to Advanced Palliative Care, 2020; National Consensus Project for Quality Palliative Care, 2018; Committee on Approaching Death, 2015). However, evidence is equivocal on the optimal approach to goals of care discussions with patients/families in the critical care...
