Japanese Incarceration Memorial As Trauma Portfolio Play, A. J. Faas, Alyssa Singh, Cibella Gamma Jan 2025

Japanese Incarceration Memorial As Trauma Portfolio Play, A. J. Faas, Alyssa Singh, Cibella Gamma

Faculty Research, Scholarly, and Creative Activity

In collaboration with the Japanese American Museum of San José, California, we examined their exhibit of WWII-era incarceration of Japanese Americans to understand how the presentation of different positionalities (e.g., Japanese/American, loyal/disloyal) engage with and contest the terms of incarceration and internal politics within the Japanese American community. In our analysis, we focus on the reproduction and contestation of particular narratives of power and identity and treat the memorial exhibit as a variety of community-based “trauma portfolio” that unsettles state bureaucratic constructions of suffering and (in)justice. We conclude by identifying transformative possibilities for engaging with the different positionalities of incarcerated …

Pain For Pain: The Benefits And Challenges Of Bdsm Participation For People With Chronic Pain–An Exploratory Study, Reni Forer, Bryce Westlake Jan 2025

Pain For Pain: The Benefits And Challenges Of Bdsm Participation For People With Chronic Pain–An Exploratory Study, Reni Forer, Bryce Westlake

Faculty Research, Scholarly, and Creative Activity

Research is beginning to find that many BDSM (bondage/discipline, domination/submission, sadism/masochism) practitioners experience benefits beyond sexual pleasure. Additionally, given the relationship between pain and pleasure common in BDSM, there may be certain unanticipated benefits for practitioners reporting chronic pain (PRCP). We conducted an online survey of an international convenience sample of BDSM practitioners (N = 525). Participants were asked about self-perceived benefits and challenges related to participating in BDSM with CP. Using chi-square, independent sample t-test, logistic regression, and linear-by-linear association, responses were combined with demographics, participation timelines, co-participants, motivations, and frequency of activities to identify differences between PRCP and …

Unmasking Public Sentiment: A Sample Efficient Approach To Analyzing Twitter Opinion On U.S. Aid To Ukraine, Satanu Ghosh, Nikhil Dewitt, Souvick Ghosh, Denise Mccoy

Faculty Research, Scholarly, and Creative Activity

The U.S. aid to Ukraine is a bipartisan topic of extreme socio-political importance. While several organizations have conducted surveys to understand the public stance on this topic, there is no research to date that analyses public opinion on social media, possibly due to the lack of annotated data. Therefore, this research compares several sample-efficient methods (including in-context learning) to analyze tweet sentiments with minimal training data. First, we collect 11,289 tweets about the U.S. aid to Ukraine and mapped them to U.S. states. Next, we explore three different approaches to sentiment analysis: tool-based, embedding-based, and prompt-based. Our results indicate that …

Faculty Research, Scholarly, and Creative Activity

Inclusive school policies and youth advocacy could promote well-being and positive development among youth of diverse sexual orientations and gender identities. Utilizing three waves of data over a 6-month period, we tested a three-level multilevel model on the extent to which youth’s advocacy in gender-sexuality alliances (GSAs; school clubs affirming youth identifying as lesbian, gay, bisexual, transgender, questioning or with other expansive sexual orientations or gender identities [LGBTQ+]) and attending schools that more thoroughly implemented LGBTQ+ inclusive policies and practices were associated with youth’s self-worth. Participants were 627 youth (87% LGBQ+ youth, 45% transgender or nonbinary youth, 48% youth of …

Why Do Some Ultra Diffuse Galaxies Have Rich Globular Cluster Systems?, Duncan A. Forbes, Maria Luisa Buzzo, Anna Ferre-Mateu, Aaron J. Romanowsky, Jonah Gannon, Jean P. Brodie, Michelle L.M. Collins Jan 2025

Why Do Some Ultra Diffuse Galaxies Have Rich Globular Cluster Systems?, Duncan A. Forbes, Maria Luisa Buzzo, Anna Ferre-Mateu, Aaron J. Romanowsky, Jonah Gannon, Jean P. Brodie, Michelle L.M. Collins

Faculty Research, Scholarly, and Creative Activity

Some ultra diffuse galaxies (UDGs) reveal many more globular clusters (GCs) than classical dwarf galaxies of the same stellar mass. These UDGs, with a mass in their GC system () approaching 10 per cent of their host galaxy stellar mass (), are also inferred to have high halo mass to stellar mass ratios (). They have been dubbed Failed Galaxies. It is unknown what role high GC formation efficiencies and/or low destruction rates play in determining the high ratios of some UDGs. Here we present a simple model, which is informed by recent JWST observations of lensed galaxies and by …

“They're Like Slash”: Multimodality And Embodied Agency In Students' Critical Engagements With Texts, María José Aragón, Meghan Corella, Nora W. Lang Jan 2025

“They're Like Slash”: Multimodality And Embodied Agency In Students' Critical Engagements With Texts, María José Aragón, Meghan Corella, Nora W. Lang

Faculty Research, Scholarly, and Creative Activity

Despite recent calls to more fully incorporate multimodal perspectives into literacies research, there is still limited scholarship examining how students critically engage in reading activities by drawing on embodied practices. Racially and linguistically minoritized students are particularly disadvantaged by dominant logocentric and developmentalist approaches, which privilege oral and written discourse and often position these students as less capable of performing complex literacy practices. Drawing from three independent ethnographic studies, our multimodal interactional analysis examines how students of a range of ages and raciolinguistic backgrounds use embodied actions and other semiotic resources to agentively navigate text, task, and ideological constraints in …

Faculty Research, Scholarly, and Creative Activity

This study compiles stellar populations and internal properties of ultra-diffuse galaxies (UDGs) to highlight correlations with their local environment, globular cluster (GC) richness, and star formation histories. Complementing our sample of 88 UDGs, we include 36 low surface brightness dwarf galaxies with UDG-like properties, referred to as NUDGes (nearly UDGs). All galaxies were studied using the same spectral energy distribution fitting methodology to explore what sets UDGs apart from other galaxies. We show that NUDGes are similar to UDGs in all properties except for being, by definition, smaller and having higher surface brightness. We find that UDGs and NUDGes show …

Separation And Surface Examination Of Spacecraft Cabin Particulates, Grace A. Belancik Jan 2025

Separation And Surface Examination Of Spacecraft Cabin Particulates, Grace A. Belancik

Master's Theses

Particulate matter in the atmosphere is a known detriment to human health, but several factors affect any particulate’s particular toxicity including particle size, surface area, and chemical composition. Extensive studies have been conducted to examine particulate hazards on Earth, but in crewed spacecraft, like the International Space Station (ISS), the particulate environment is wholly unique due to both the controlled environment and lack of gravity. Atmospheric sampling studies are underway, but another convenient source of airborne particulates for analysis is the contents of the vacuum bags used by the astronauts to clean the air vents. However, no method currently exists …

The Inequitable Access: Black And Latinx Students In Ap Courses, Jean C. Woolcock Jan 2025

The Inequitable Access: Black And Latinx Students In Ap Courses, Jean C. Woolcock

Dissertations

This study posits that in American high schools, the preparation of Black and Latinx students, starting from the freshman year, can be effective in helping to increase their participation in Advanced Placement (AP) courses. Structural inequities, in how schools are resourced, affect the ways in which Black and Latinx students are denied equal opportunities. On the contrary, members of their peers do obtain this kind of preparation. As a framework, Critical Race Theory (CRT) contends that race, the law, and power are deeply ingrained in maintaining established bastions of wealth and dominance. Gaps in opportunity and achievement spill over into …

"Acoustical Bedlam": A Contextualization Of Beethoven's Christus, Leanna R. York Jan 2025

"Acoustical Bedlam": A Contextualization Of Beethoven's Christus, Leanna R. York

The Beethoven Journal

The premiere of Beethoven’s Christus am Ölberge at the Theater an der Wien on April 5, 1803, marked the composer’s first and only contribution to the complex tradition of the German oratorio. Since the genre’s inception at the turn of the eighteenth century, it reflected artistic, literary, and theological controversies of its day. Beethoven’s chosen theme, the passion of Christ, came with its own set of ever-shifting compositional and textual expectations, influenced by older traditions of sepolcri and staged oratorios (common in Vienna and at the court of the elector of Cologne after mid-century) and lyric works such as Graun’s …

Moral Intensity Dimensions Of Information Security Policy Compliance: Perspectives Of Construal Level Theory And Ethical Theories, Dailin Zheng, Zhiping Walter Jan 2025

Moral Intensity Dimensions Of Information Security Policy Compliance: Perspectives Of Construal Level Theory And Ethical Theories, Dailin Zheng, Zhiping Walter

Faculty Research, Scholarly, and Creative Activity

Sanctions are often ineffective in promoting employee compliance with information systems security policies (ISSPs) and may lead to undesired outcomes. We establish that ISSP compliance is an ethical decision and examine it through the lens of ethical decision-making using scenario-based surveys. Guided by normative ethical theories and the construal level theory, we find that both the opinions of co-workers and perceived negative consequences of noncompliance to the organization influence employee ISSP compliance intention. Additionally, perceived social distance affects employees' assessment of when damages to the organization can occur. Both the assessed timing of damage and the perceived social distance from …

Faculty Research, Scholarly, and Creative Activity

In October of 2022, the US Food and Drug Administration finalized regulations establishing the category of self-fitting over-the-counter (OTC) hearing aids, intended to reduce barriers to hearing aid adoption for individuals with self-perceived mild to moderate hearing loss. Since then a number of self-fitting OTC hearing aids have entered the market, and a small number of published studies have demonstrated the effectiveness of a self-fitted OTC intervention against a traditional clinician-fitted intervention. Given the variety of self-fitting approaches available, and the small number of studies demonstrating effectiveness, the goal of the present study was to evaluate the effectiveness of a …

Fences On The Epistemological Prairie: A Settler Colonial Approach To “Religion And Science”, Lisa L. Stenmark Jan 2025

Fences On The Epistemological Prairie: A Settler Colonial Approach To “Religion And Science”, Lisa L. Stenmark

Faculty Research, Scholarly, and Creative Activity

Building on the idea of religion and science as conceptual maps of intellectual territory, I use a settler colonial analysis as a framework for thinking about decolonizing religion and science in a way that moves away from abstraction and towards action; addressing not just the ideas, but the tools of control—the fences—that impose ideas on the territory itself. Comparing the Wyoming prairie with the epistemological prairie, I describe the maps, fences and other tools and technologies of settler colonialism used to appropriate Indigenous Land and knowledge, eventually turning it into private property. It is in this last step—the creation of …

Background: In available comparative studies, Dutch transgender youth have consistently shown better psychosocial well-being compared to those in other countries. Therefore, the Netherlands (N.L.) could be considered a gold-standard—though imperfect—comparator for transgender youth research. The United States (U.S.) is heterogeneous in its policies and practices impacting transgender youth, and policies are in flux. This study examines similarities and differences between U.S. and Dutch policies, practices, and contexts relevant to the well-being of transgender adolescents. Methods: A three-stage Delphi procedure was conducted with expert panels in the N.L. and U.S. Results: This process identified candidate mechanisms driving differences in outcomes for …

An increasing number of studies find that water sharing—the non-market transfer of privately held water between households—is a ubiquitous informal practice around the world and a primary way that households respond to water insecurity. Yet, a key question about household water sharing remains: is water sharing a viable path that can help advance household water security? Or should water sharing be understood as a symptom of water insecurity in wait for more formalized solutions? Here, we address this question by applying Sen’s entitlement framework in an integrative review of empirical scholarship on household water sharing. Our review shows that when …

Autoregressive Neural Quantum States Of Fermi Hubbard Models, Eduardo Ibarra-García-Padilla, Hannah Lange, Roger G. Melko, Richard T. Scalettar, Juan Carrasquilla, Annabelle Bohrdt, Ehsan Khatami

Faculty Research, Scholarly, and Creative Activity

Neural quantum states (NQSs) have emerged as a powerful ansatz for variational quantum Monte Carlo studies of strongly correlated systems. Here, we apply recurrent neural networks (RNNs) and autoregressive transformer neural networks to the Fermi-Hubbard and the (non-Hermitian) Hatano-Nelson-Hubbard models in one and two dimensions. In both cases, we observe that the convergence of the RNN ansatz is challenged when increasing the interaction strength. We present a physically motivated and easy-to-implement strategy for improving the optimization, namely, by ramping of the model parameters. Furthermore, we investigate the advantages and disadvantages of the autoregressive sampling property of both network architectures. For …

NGC 1052-DF2 and -DF4 are two ultradiffuse galaxies that have been reported as deficient in dark matter and associated with the same galaxy group. Recent findings suggest that DF2 and DF4 are part of a large linear substructure of dwarf galaxies that could have been formed from a high-velocity head-on encounter of two gas-rich galaxies, known as a “bullet dwarf” collision. Based on new observations from the Hubble Space Telescope, combined with existing imaging from the u band to mid-infrared, we test the bullet dwarf scenario by studying the morphologies and stellar populations of the trail dwarfs. We find no …
