Becoming Stewards Of Attention: A Theological Appeal, Joshua Gorenflo

Electronic Theses and Dissertations

The widespread compromising of attention currently taking place in our digital age is, at least in part, a theological issue necessitating a theological response, which invites an examination of the human person in relation to God. Familiar within the biblical narrative and throughout Christian tradition, I suggest that when the role of steward functions as the operative paradigm for humans, the claims made upon their lives have profound implications for attending within the digital age. More specifically, the steward’s attention becomes a tangible expression of authority and accountability in representation of God’s image to the rest of creation. In pursuit …

Gen Z Students’ Experiences With College Choice, Heather Levesque

Electronic Theses and Dissertations

The purpose of this qualitative study was to explore what influences Gen Z student college choice. Research on college choice has provided insight into whether or not a student will attend college; however, limited research exists on what impacts Gen Z students’ college choice and how marketing and communication influence what college a student will choose. College recruitment has always been challenging, given the high competition between colleges and universities. With the decrease in enrollment over the last decade and the unexpected impact of COVID-19, that challenge continues to grow. Enrollment and marketing administrators have difficulty expanding and diversifying their …

The Whale-Road To Road House: A Study Of The Contemporary Transmission Of Beowulf, Haley Grindstaff

Electronic Theses and Dissertations

This thesis explores three versions of Beowulf: Gareth Hinds’s graphic novel Beowulf (2007), Maria Dahvana Headley’s translation Beowulf (2020), and Rowdy Herrington’s film Road House (1989). While Hinds and Headley fail to convey Beowulf as a cultural elegy by subtracting or misrepresenting significant scenes and characters, Road House superimposes the story of Beowulf onto 1980s America. Parallels between the plots of Beowulf and Road House and Road House’s interaction with the political underpinnings of the 80s (such as Reaganomics and the AIDS epidemic) make the film one of the best at capturing the elements of cultural elegy in the …

Knockdown Of C. Elegans Nad Kinases Nadk-1 Or Nadk-2 Induces An Antioxidant Response Without Affecting Lifespan, Henry Gong

Electronic Theses and Dissertations

Nearly all multicellular organisms show changes in redox balance with aging leading to oxidative damage of macromolecules. This study investigated the role of the [NADP⁺]/[NADPH] redox couple in aging. This redox couple plays an important role in maintaining tissue redox balance and becomes slightly more oxidized in aged tissues. NADPH is a major source of reducing equivalents for enzymes that detoxify hydrogen peroxide. However, catalase detoxifies hydrogen peroxide independently of NADPH. But catalase is absent from mitochondria, a major source of hydrogen peroxide, where instead glutathione plays the major role in hydrogen peroxide detoxification in an NADPH-dependent manner. …

The Comparative Effects Of Three Virtual Nature Exposure Methods On State Social Motivation: A Randomized Controlled Trial, Samantha A. Castelblanco

Electronic Theses and Dissertations

It is well established in the research literature that exposure to nature positively affects physical and mental health. However, research regarding the effects of nature exposure on social health is less developed. Prior research found that watching a video of nature improved state social motivation. Building on this research, the current study compared the effects of three methods of virtual nature exposure on state social motivation in a randomized controlled trial. In this 3X3 between-subjects experiment, participants (N = 426) 18 to 73 (M_Age = 27.69, SD = 12.19) were randomly assigned to experience 3-minutes of nature …

Operatic Mysticisms: Mountains, Deserts, Waterscapes, Andrew Demczuk

Electronic Theses and Dissertations

Operatic Mysticisms: Mountains, Deserts, Waterscapes examines the ways we encounter environments as readers/viewers of operas, literature, film, and sound recordings, and how each medium requires different detail-gathering techniques. Respective to the previously mentioned mediums, Sun & Sea (2017), Mount Analogue (1952), El Mar La Mar (2017), and Energy Field (2010) are analyzed by engaging with environmental media studies and invention. Reflecting the nature of each landscape—summits of mountains, aporias of deserts, and mysteries of waterscapes—an elemental approach is taken in investigating how these spaces may be noticed, internalized, recorded, and traversed by both the artist and viewer. …

Social-Emotional Learning: A Literature Review, Stella M. Westhoven

Electronic Theses and Dissertations

ABSTRACT

Social-emotional learning targets the development of positive interpersonal relationships, empathy, emotional regulation, healthy identities, personal/collective goal orientation, and responsibility in the decision-making process (CASEL Organization, 2021). Schools, however, have the main objective of ensuring that academic measures are met. Linking social-emotional learning and skills to the school system’s principal goal, academic results, can facilitate the greater implementation of such programs within the school setting. This systematic literature review examined the relationship between social-emotional learning programs in schools and academic outcomes, such as grades, test scores, or grade point averages. Secondly, it explored the relationship between students’ social-emotional skills and …

Public Health Contagion Of White Supremacy: Examining The Pipeline Of Attitudes About Racism And Racial History Education Among High School Students., Trinidad Jackson

Electronic Theses and Dissertations

We are living in compounded states of upheaval. Violence and exemption from it across socioecological levels have shaped how humans survive, thrive, and die. While different violence typologies exist, the U.S., prioritizes interpersonal violence as its primary target of intervention, often through structural means that foster and reinforce interpersonal violence. The omission of structural and cultural agents and outcomes of violence allows perpetrators to infiltrate and reproduce savage, dehumanizing ideologies in perpetuity. Instead of sustaining societal pillars that oppress and destroy, we must fertilize public health research, practice, and sociopolitical activism with pillars that both inform and activate liberatory consciousness …

Etracellular Vesicles From Lactobacillus Rhamnosus Gg Protect Against Alcohol-Induced Liver Injury Through Suppression Of Intestinal Mir 194 And Subsequent Activation Of Fxr In Mice., Mengwei Jiang

Electronic Theses and Dissertations

Numerous studies have reported the efficacy of probiotics for alcohol-associated liver disease (ALD). These studies indicate a strong interest among the scientific and medical communities in identifying alternative or adjunctive approaches for ALD, for which there is no effective or widely accepted therapeutic option. However, in-depth molecular knowledge on how probiotics render their effects is lacking. Patients with ALD often have increased hepatic bile acids (BAs), which can be toxic and are an important causative factor in liver injury and hepatocyte death. BAs are released into the intestines and serve not only as a “detergent” to promote fat absorption, but …

Structural, Charge Transport, Gas Sensing, Magnetic, Pseudocapacitive, And Electrocatalytic Properties Of Perovskite Oxides., Surendra Bahadur Karki

Electronic Theses and Dissertations

Perovskites are functional materials with the general formula ABO₃ (A = alkali, alkaline earth or lanthanoid cations and B = transition metal or main group cations). These materials are marked by a variety of crystal structures and interesting properties such as colossal magnetoresistance, ferroelectricity, multiferroicity, superconductivity, pseudocapacitance, gas sensing, charge transport, and electrocatalytic properties. The formula of perovskite can be written as AA’BB’O₆, when there is ordering between two cations over A and B-sites. Such compounds are called double perovskite oxides. Some amount of oxygen could be lost from crystal structure without decomposition of the phase. Such …

Mission Drift And The Effectiveness Of Resource Dependence Theory In An Internally Resource-Constrained Environment., Kirsten Bullock

Electronic Theses and Dissertations

Why are some organizations able to maintain focus on their mission while others founder? This theoretical and empirical dissertation examines the relationships among funding sources, management practices, and organizational stigma within an internally resource-constrained environment. Using Resource Dependence Theory (RDT) as a basis to manage external resource dependencies, I build a theoretical model and empirically test a research model to understand how funding source affects mission drift, how management practices might help organizations manage that drift, and what effect organizational stigma might have on those relationships within an environment of internal resource constraints. Specifically, this study hypothesizes that nonprofits that …

The Water We Were Swimming In: Transgender And Gender Nonconforming Students' Lived Experiences In Engineering., Natalie Saroff Oliner

Electronic Theses and Dissertations

Few studies address the lived experiences of transgender and gender nonconforming (TGNC) students in engineering. Grounded in critical trans politics (Spade, 2015), this dissertation contributes to the literature on TGNC students in engineering by examining their experiences negotiating their identities while navigating interrelated systems of oppression in a field dominated by White, heterosexual, cisgender men. Using a critical constructivism framework, I conducted a narrative inquiry to explore the lived experiences of five TGNC students in engineering programs. Participants experienced TGNC oppression at their universities, built LGBTQ+ and TGNC communities, and described more welcoming climates in non-engineering contexts compared to engineering. …

The Role Of Accuracy In Children’S Judgments Of Experts’ Knowledge., Allison J. Williams

Electronic Theses and Dissertations

Children prefer to trust people with expertise and people who are accurate. Because experts make mistakes and give incorrect information (e.g., predictions and diagnoses), this dissertation explores children’s judgments of knowledge for experts who provide inaccurate information. Across two studies, 6- to 9-years-olds (N = 160) were introduced to two experts in different domains (doctor and mechanic) and rated how much each expert knows about their relevant domain. Then, over four consecutive trials, participants heard one expert give inaccurate answers to easy questions in their domain. After each trial, children explained why they believed the expert gave inaccurate answers …

Authentically (Un)Real Assessing Vh!'S Basketball Wives And Its Violent & Colorist Portrayals Of Black Women., Wilma Denae Powell

Electronic Theses and Dissertations

Does reality television serve as solely a form of entertainment, or could reality television also be maintaining hegemonic beliefs and reinforcing biased views of Black women? Since 2010, Vh1’s Basketball Wives has given audiences the opportunities to entertain themselves by watching women who are/were married to, dating, or are the mothers of children fathered by professional basketball players. Despite the show’s name, few members of the cast are currently married and audiences only get mere glimpses of the cast in motherly or marital interactions. So, what does Basketball Wives offer audiences who tune in to watch Black women for entertainment? …

Characterization Of Fundamental Parameters That Modulate Acoustofluidic-Mediated Molecular Delivery To Cells., Connor Sterling Centner

Electronic Theses and Dissertations

Cell-based therapies represent the latest biotechnological revolution in medicine, but significant limitations exist in non-viral intracellular delivery techniques during manufacturing of cell therapies. To address these limitations, a novel acoustofluidic device was developed to deliver ultrasound waves into a flow chamber for rapid molecular delivery to human cells. Our acoustofluidic device delivers biomolecules by inducing expansion and collapse of exogenous gas-filled microbubbles (“cavitation”), which enhances molecular delivery to nearby cells. Experimental studies were conducted to characterize key parameters that influence acoustofluidic-mediated molecular delivery to human cells. A clinical ultrasound transducer was generally utilized with varying cationic microbubble concentrations. Intracellular delivery …

Materials And Interfaces For Electrocatalytic Hydrogen Production And Utilization., Alexander Jiya Gupta

Electronic Theses and Dissertations

Mass industrialization over the last few centuries has created a global economy which is dependent upon fossil fuels to satisfy an exponentially increasing demand for energy. Aside from the possible depletion of this finite resource, the combustion of fossil fuels releases greenhouse gases into the atmosphere which cause the global temperature to rise – a phenomenon which has already begun to create geologic and geopolitical instability and shows no signs of abatement. One proposed method to rid humanity of its dependence on fossil fuels is to use green hydrogen as an energy carrier. In this scheme, excess electricity from a …

Particulate Hexavalent Chromium Inhibits Homologous Recombination Repair By Targeting Rad51 Paralogs In Human Lung Fibroblasts., Aggie R. Williams

Electronic Theses and Dissertations

Hexavalent Chromium [Cr(VI)] is a known human lung carcinogen and general health hazard. The mechanism of carcinogenesis remains poorly understood, but chromosome instability (CIN) is the major theory in its carcinogenic mechanism. Homologous recombination (HR) repair is a DNA repair pathway that prevents CIN by repairing DNA double-strand breaks. RAD51, a key mediator protein of HR repair, along with the RAD51 paralogs (RAD51B, C, D, XRCC2, and 3) are required for HR repair. During HR, RAD51 loads and forms a helical nucleoprotein filament structure to promote DNA strand exchange and stimulate pairing activity of DNA. Cr(VI) exposures have been shown …
