Ai-Generated Text Detection And Source Identification, Anjana Priyatham Tatavarthi, Faranak Abri, Nada Attar

Faculty Research, Scholarly, and Creative Activity

The use of advanced machine learning techniques to detect AI-generated text is a very practical application. The ability to distinguish human-written content from machine-generated text while identifying the source generative model helps address growing concerns about authenticity and accountability in digital communication. The differentiation of human-generated and AI-generated text is highly relevant to several applications, from news media to academic integrity, and is key to ensuring transparency and trust in content-driven environments. However, existing models are often insufficient to accurately detect AI-generated text and determine the specific AI source due to the complex nature of machine-generated content. To address this, …

Collective Liberation Through Critical Pedagogy, Robert A. Marx, Anne E. Dufault, Miriam R. Arbeit

Faculty Research, Scholarly, and Creative Activity

The collective liberation of queer and trans people—which is inherently tied to the liberation of those oppressed by white supremacy and racism, ableism, classism, ageism, and other asymmetrical power distributions—is possible when we develop critical consciousness through critical pedagogy. As young people develop an awareness of the contradictions and falsehoods they are taught (e.g., the myth of meritocracy), they begin to work to change their environments and offer resistance to the structures that inequitably shape their world. The vast majority of research on queer and trans adolescents, though, has been shaped by dominant, deficit-based views of queerness that presuppose that …

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 …

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 …

A Privacy-Preserving Federated Learning Approach For Airline Upgrade Optimization, Sien Chen, Yinghua Huang

Faculty Research, Scholarly, and Creative Activity

Purpose: A key issue of making upgrade decisions is to match the most relevant upgrade offers to the right customers at the right time. To optimize upgrade strategies and profitability, companies seek to break “data silos” between themselves and other business partners for a more holistic view of customers' consumption experiences. However, multi-source data fusion may lead to potential privacy leakage. To overcome these two challenges in data silos and privacy protection, this study introduced a privacy-preserving federated learning (FL) approach and explained the process of using FL in modeling airline passengers’ willingness to pay for upgrade offers. Design/methodology/approach: Federated …

Gray Matter Volumetric Changes In Tinnitus: The Impact Of Hearing Loss And Severity, Gibbeum Kim, Rafay A. Khan, Yihsin Tai, Somayeh Shahsavarani, Fatima T. Husain

Faculty Research, Scholarly, and Creative Activity

Tinnitus is a phantom auditory sensation that commonly co-occurs with hearing loss. Both tinnitus and hearing loss can impact the quality of life, emotional well-being, and cognitive functioning of the affected individuals. While previous studies have highlighted structural alterations in hearing loss and/or tinnitus, the fundamental neural mechanisms underpinning tinnitus severity remain poorly understood. In this study, we conducted a voxel-based morphometry to investigate gray matter (GM) volume differences among groups of participants with varying tinnitus severity and hearing status, and controls within a large sample. We observed reduced GM volume in the left anterior insula and right planum polare …

Rift - Reddit Information Falsity Tagger, Parth Joshi

Master's Projects

Social media platforms such as Reddit are widely used for sharing and consuming information. User-generated content poses a great risk for misinformation creation and dissemination on these platforms. “Fake news”, as it is commonly referred to, has far-reaching social implications, swaying public perception, making political viewpoints more radical, and adversely impacting health decisions. The covariable features that come with fake news make it even harder to detect because it is presented in the form of text, images, videos, and even social interactions. This paper describes a novel method for detecting fake news on Reddit: RIFT, short for Reddit Information Falsity …

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 …

The research reviewed teacher and administrator perceptions by focusing on three high school teachers who taught Long Term English Learners during the study period to understand the reclassification process. The researcher interviewed a district-level administrator to understand institutional policies and procedures that determine LTEL student identification and reclassification processes. The researcher presented their autoethnographic narrative to explore how holistic measures support multilingual …

"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 …

Innovative Sonorities: Atypical Pitch Orders In Beethoven's Piano Trios, Yoko Maruyama

The Beethoven Journal

In his chamber music with keyboard, Beethoven famously emancipated the cello from its bass function to make it equal with the other instruments, as has been repeatedly noted. Some studies have also highlighted, partly in relation to this emancipation, the sonorous balance between strings and piano in Beethoven’s chamber works. The pitch relationship between the cello and violin in his piano trios has been less discussed, yet attending to both parts reveals a tendency to use an atypical order in which the cello’s pitch is set above the violin or between the violin’s chord tones. This tendency increases from Beethoven’s …

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 …

Thirty years later, this study surveys the current availability and preservation status of those 443 journals. While a significant number of these journals are no longer available, the results indicate that independent preservation efforts by individuals and small groups were a major factor in preserving many of the remaining publications. This study uses the preservation survey method to assess the preservation environment for these journals, and also to build an online directory of the …

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 …

Can Household Water Sharing Advance Water Security? An Integrative Review Of Water Entitlements And Entitlement Failures, Melissa Beresford, Ellis Adams, Jessica Budds, Leila M. Harris, Wendy Jepson, Tennille Marley, Chloe Nguyen, Amber Pearson, Anaís Delilah Roque, Asher Y. Rosinger, Sameer H. Shah, Matthew Stellbauer, Amber Wutich

Faculty Research, Scholarly, and Creative Activity

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 …
