Ensemble Perception Of Emotion: Incidental Effects Of Social Identity, Spencer T. Dobbs

Electronic Theses and Dissertations

Research in vision science suggests that people possess a perceptual mechanism – ensemble perception - which enables them to rapidly identify the characteristics of groups (e.g., emotion, sex-ratio, race-ratio). This work examined whether ensemble perceptions of groups are driven by the characteristics of group members whose behavior is most likely to impact the perceiver. Specifically, we predicted that more self-relevant group members would be weighted more heavily in ensemble perceptions than less self-relevant group members. Study 1 (n = 83) found that young adult participants’ ensemble perceptions of emotion were biased in favor of more self-relevant (younger adult) group …

Paradoxes And Potential Of Tourism Development In Nicaragua, Cody J. Silveira

Electronic Theses and Dissertations

This dissertation research evaluates the successes and challenges of tourism integration and expansion as both a broad human development strategy and a catalyst for local populations to achieve greater economic and social opportunities. The country of Nicaragua serves as the primary case study for such an evaluation due to its relatively recent promotion and expansion of tourism through government led incentives and oversight. As a case study, Nicaragua is a country whose tourism industry remains nascent, yet commands great economic potential and influence, which can serve as an example for future tourism development initiatives for developing countries in the region …

Document review, interviews, and journaling activities with ten participants were the primary methods of data collection. Key findings from this dissertation include a grounded theory explaining the current state of preparation for youth services librarianship, and multiple avenues for further study.

Changing The Narrative: Student Empowerment In Unequal School Contexts, Stephanie A. Nisle-Mikos

Electronic Theses and Dissertations

Educational experiences affect a wide variety of life outcomes for individuals. The type of education an individual receives influences their occupation, the neighborhood in which they live, and even their risk of mortality (National Research Council, 2013; Sasson, 2016). In particular, the life trajectories of students who attend high-poverty schools are not the same as youth who attend schools with greater resources (National Center for Education Statistics [NCES], 2013; Taylor, 2005). In this dissertation, I provide a brief background on current rates of disproportionality in education and examine how specific theoretical constructs and educational policies may be used to explain …

The Role Of Care Practices, Mutual Aid, And Racial Formation In Black Newcomer Practitioners’ Lived Experience Within Organizations: A Critical Qualitative Inquiry, Annie Zean Dunbar

Electronic Theses and Dissertations

Black newcomers, defined as people who have migrated to the United States regardless of legal status, are one of the fastest-growing immigrant groups. (Morgan-Trostle et al., 2016). Within this population, a small percentage work within the social service sector with other migrants. Using critical qualitative methods, a critical phenomenological methodology and semi-structured interviews, a sample of 17 participants were asked about their experiences of living and working in the U.S. social service sector. The study uses racial formation theory (Omi & Winant, 2014) to conceptualize how participants experienced their racial identity formation and how racism shapes their personal and professional …

Characterization Of Oxidized Tau Protein Aggregation And Inhibition Of Tau Aggregation Via Map2, Brad Krzesinski

Electronic Theses and Dissertations

Neurofibrillary tangles (NFT) composed of the microtubule stabilizing protein Tau are a pathological hallmark of Alzheimer's disease (AD) and many other dementia related diseases specified as Tauopathies. Due to alternative mRNA splicing, intrinsically disordered Tau exists as six separate isoforms in the adult human brain where they are categorized by the lack or inclusion of the second repeat in the microtubule binding domain (3R or 4R respectively). Isoforms are subcategorized by the inclusion or lack thereof, one or two N-terminal inserts. Many studies show that Tau aggregates into amyloid fibrils and these fibrils can break into small oligomeric units known …

Progressive Paradox In Political Rhetoric: The Hart-Celler Immigration Act Of 1965, Amanda Rolston Henderson

Electronic Theses and Dissertations

This dissertation investigates the interplay between U.S. norms for inclusion, the embedded role of religion within these norms, and how political rhetoric challenges or sustains them. Using a historical lens, I outline key moments in U.S. history, unravel central ideologies entrenched in U.S. narratives, and illuminate the ideographic function of the key concepts land, family, and work. These terms serve as conduits for conveying complex systems of meaning, which are entrenched in societal assumptions and concretized through political discourse and action.

These dynamics are demonstrated in a case study of the discourse surrounding the Hart-Celler Immigration Act …

Understanding The Nuances Of Transit Accessibility: Temporal And Spatial Resolution, And Neoliberalism, Joe Chestnut

Electronic Theses and Dissertations

This dissertation explores accessibility via public transit through several lenses. In doing so, some of the lesser known nuances of accessibility are better understood. These nuances are explored in several ways. First, various demographic variables and their relationship to accessibility to jobs via public transit are modeled at a fine spatial resolution in an exploratory analysis across several cities in the United States. Next, temporal and spatial resolution and their impacts on accessibility to jobs via public transit are analyzed and quantified in several cities across the United States. Finally, the relationship between neoliberalism and public transit accessibility is explored …

Rhetorical Resonances: An Affective Logic Of Emergence In Space And Time, Craig R. Weathers

Electronic Theses and Dissertations

This project explores the affective circulation of controversy in contemporary public discourse through a rhetorical ecological approach. It addresses the problem of how flattened conceptions of power and social movements cast in binary opposition prevent effective deliberation around public controversies. The research method involves analyzing three case studies through a new framework for rhetorical studies, called a logic of emergence, to consider the resonance and trajectories of actants (individuals, groups, and institutions) in conflict. The first case study examines the Unite the Right rally in Charlottesville and the discursive equating of antifa and the Alt-Right. The second case analyzes the …

The Entrepreneur’S Burden: Investigating The Interplay Between Impostorism And Entrepreneurial Identity, Megan Laura Weber

Electronic Theses and Dissertations

Entrepreneurship is often portrayed as a glamorous pursuit of success but conceals a darker side, exacerbated by impostorism, characterized by challenges, identity conflicts, and diminished well-being. This "dark side" of entrepreneurship is seldom explored due to our collective fascination with the central figure of the entrepreneur. Impostorism is a prevalent phenomenon among individuals who perceive that their role is beyond their capabilities and fear being exposed as a "fake." Impostorism can have negative consequences, including self-sabotage, missed opportunities, and difficulty in seeking help or support, which can impact the ability of entrepreneurs to take entrepreneurial action and experience well-being.

This …

The Power Behind Postsecondary Attainment Goals: A Critical Policy Discourse Analysis, Casey Mccoy-Simmons

Electronic Theses and Dissertations

In this study, I examined neoliberal discourses upheld by policy actors engaged in the college completion agenda that perpetuated power structures maintaining white supremacy by relying on the success of racially marginalized communities to meet postsecondary attainment goals. With philanthropic foundations playing an increased role in advancing an advocacy-focused agenda to increase postsecondary attainment across states, there was also a need to better understand the relationship between state policy actors and foundations. As a national champion of postsecondary attainment goals, I identified the Lumina Foundation as a key policy actor in leveraging its advocacy-focused agenda to influence state policy actors …

Understanding The Misunderstandings: Using Deliberative Democracy And Communication Ethics To Overcome Societal Polarization In Post-Truth America, Jessica Neu

Electronic Theses and Dissertations

This work contributes to communication scholarship by advancing the discussion of deliberative democracy to include communication ethics and popular culture artifacts to use as case studies in an exploration of how to engage in a type of dialogic civility that acknowledges identity politics without allowing it to be a barrier to progress in a post-truth society. As such, this work provides a sense of how to engage in conversation that recognizes and hears the Other in a way that makes all stakeholders uncomfortable. From this discomfort comes growth, as individuals do not necessarily need to completely alter their ideologies, morals, …

Are Clinicians Primed For Burnout?: A Multidiscplinary Approach To Exploring Counselor Wellness, Anastasha Homa-Earl

Electronic Theses and Dissertations

Though clinician wellness is a “hot topic” in the field of counseling, the current models of examining counselors’ levels of burnout and engagement do not account for the likely role that perception plays the subjective experiences of these constructs. This project attempts to synthesize methodology from the fields of social and cognitive psychology with the latest in industrial-organizational theory on burnout and engagement by applying a priming methodology to the study of mental health professionals’ experiences of work-related burnout and engagement. One hundred sixty-two clinicians participated in a priming experiment disguised as a workplace perceptions survey in an attempt to …

Inclusion Of The Virtual Other: How Closeness On Social Media Moderates The Relationship Between Perceptions Of Close Friends’ Alcohol-Related Posting And Drinking, Angela Tanygin

Electronic Theses and Dissertations

Heavy drinking among young adults is a serious, longstanding public health issue. College students are particularly vulnerable to a culture of intoxication that promotes excessive drinking, which has been linked to severe consequences such as sexual assaults, car accidents, and even death. An abundance of literature has found that students’ overestimations of peer drinking norms are associated with greater alcohol use and problems. Furthermore, research has established a strong linkage between students posting and viewing peers’ alcohol-related content (ARC) on social media and increased drinking. However, there is a dearth of studies examining how closeness to close friends on social …

The Ecclesiology Of Catalino G. Arévalo: Inculturation, Mission, And Liberation In The Philippine Context, Zachary Ryan Dehm

Electronic Theses and Dissertations

Catalino G. Arévalo, S.J., was an eminent Filipino ecclesiologist of the twentieth and twenty-first centuries. Through his work for the Federation of Asian Bishops’ Conferences in particular, he played a significant role in the reception of the Second Vatican Council (1962-1965) in Asia and in the development of inculturation as a theological norm. Yet, Arévalo offered no systematic articulation of his theology of the church. By examining his work spanning seven decades, this dissertation traces the development of Arévalo’s ecclesiology and offers five foundational principles necessary for gaining a systematic understanding of his thought: (1) ecclesiology must be situated within …

Circumcision—Deal With It! A Clinical Ethnography Of Intactivism At American Intersections, Benjamin M. Gaddes

Electronic Theses and Dissertations

On a routine trip to the grocery store, or while scrolling online, you might encounter the provocative and puzzling discourse of Intactivism, a viral, single-issue social movement that opposes infant male circumcision, and wonder “Huh? Why is this here, now?” This project situates Intactivism in a history of circumcision and anti-circumcision that spans from ancient Sumerian tents to the front pages of Reddit. It takes an immersive qualitative clinical ethnographic approach, nested in a broader cultural psychology that is non-reductive and pluralistic, to articulate an Intactivist ethos in its public and private dimensions. Methods include participant-observation, interviews, and framework discourse …

Electronic Theses and Dissertations

This study will attempt to facilitate a more helpful reading of the text of John’s Apocalypse by placing it in an appropriate literary and historical context, deploying an African American hermeneutic, informed by the work of African American commentators such as Brian Blount, Allen Dwight Callahan, Clarice Martin, and Shanell T. Smith to develop from the text of the Apocalypse its ecclesiological content for a contemporary audience. As the church writ large (Catholic, Orthodox, Protestant and indigenous expressions) wrestles with its increasing global presence and the cultural and linguistic diversity which that expanded presence creates, this study will attempt to …

Evaluation Of Changes In Evaporative Losses From Lake Powell Reservoir Contributions In The Colorado River Basin, Maria Mlinarcik

Electronic Theses and Dissertations

The Colorado River Basin (CRB) is one of the most critical water sources for the western United States (U.S.) and Mexico. For over a century, numerous policies and regulations have been implemented in attempts to manage the Colorado River Basin to address the concern of overuse, collectively referred to as the “Law of the River.” The USGS hydrologist E.C. LaRue warned that the optimistic estimates used in negotiating the Colorado River Compact did not align with the actual water availability in the river. His analysis in 1925 revealed a potential deficit if all allocated water was utilized, exacerbated by overallocation …

Impact Of Glycerophosphocholine Metabolism On Phenotypes In Saccharomyces Cerevisiae And Schizosaccharomyces Pombe, Victoria Hrach

Electronic Theses and Dissertations

Glycerophosphocholine (GPC) is an abundant metabolite in eukaryotes. In baker’s yeast, Saccharomyces cerevisiae, GPC can be produced via deacylation of the major membrane glycerophospholipid phosphatidylcholine (PC). My lab has identified a novel pathway to re-synthesize PC from GPC by acylating it at the sn-1 and sn-2 positions; this pathway has been termed the PC Deacylation-Reacylation Pathway (PC-DRP). We previously characterized the acyltransferase Gpc1 and its ability to synthesize one-tailed lyso-PC from GPC, as well as that noting that GPC1 is upregulated in inositol-free conditions and results in more saturated PC. Here, I add to this basic characterization by establishing …

Characterization Of A Novel Metalloid Reductase Outer Membrane Porin Rara From Sulfurospirillum Barnesii Ses-3, Narthana Jeganathar Kanmanii

Electronic Theses and Dissertations

Sulfurospirillum barnesii SES-3 is a gram-negative epsilon proteobacterium that grows anaerobically by coupling the oxidation of lactate to the reduction of arsenate. Previous work on metal and metalloid metabolism in S. barnesii had identified a redox active protein, designated RarA that when provided an artificial electron donor (i.e., reduced methyl viologen, FMN, or NADH), could reduce a variety of substrates, including arsenate, selenate, selenite, nitrite, and even phosphate. The enzyme’s inferred amino acid sequence showed weak similarity (30%) to outer membrane porins with homologs found in only certain species of Sulfurospirillum. Further, the enzyme did not contain cysteine residues …

Quaternary Diamond-Like Sulfides For Nonlinear Optical Applications: Investigation Into Composition-Structure-Property Relationships Of The I2-Ii-Iv-Vi4 And I4-Ii-Iv2-Vi7 Formulae, Jordan Kelly

Electronic Theses and Dissertations

The research work presented in this dissertation focuses on the synthesis, characterization, and property assessment of new and existing quaternary diamond-like semiconductor (DLS) materials for the potential application in infrared (IR) nonlinear optics (NLO). Chapter 2 discusses the previously discovered temperature-dependent polymorphs of Cu₂ZnGeS₄ (CZGS); however, the IR NLO properties, neutron powder diffraction data, and single crystal X-ray diffraction structures were previously undetermined. The high-temperature α-CZGS polymorph was superior to the low-temperature β-CZGS analog in both second harmonic generation (SHG) and laser-induced damage threshold (LIDT). Chapter 3 presents the discovery of Li₂MgGeS₄ and comparison …
