General And Special Relativity May Explain The Hubble Tension And Galactic Rotation, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

Using two equations from general and special relativity, one can explore the hypothesis that gravitational time dilation and the relativistic Doppler effect cause the Hubble tension. Predicted results show good agreement between theory and observation, as long as mass is restricted to ordinary baryonic matter. This unexpected finding suggested a surprising continuation, namely that observed galactic rotation also be explained by special relativity. This idea survived initial tests using both Vera Rubin’s original data and more recent observations.

Mapping The Multifarious Image In Time Of Globalization, Anne-Laure Oberson

Artl@s Bulletin

Abstract: In this paper, I examine the evolving concept of the image, exploring the philosophical implications of its complex, multifaceted nature. I question the value of terms such as icon, simulacrum, and image in reference to Gilles Deleuze’s text Difference and Repetition. I argue for a pluralistic approach to understanding images as they embody more than a duality of visible-invisible dimensions. I seek to capture the multifariousness of the image to understand its transformative power. In conclusion, the paper suggests reevaluating image discourse to better engage with the evolution of its implications in a global context.

A Deluge Of Sea Images: Maritime Art And Temporal Crisis, Jonathan Stafford

Artl@s Bulletin

Abstract: We are today inundated with images of the sea, with maritime representations of global trade, the refugee crisis, and climate collapse featuring prominently in both journalistic and artistic image worlds alike. These seascapes seem to be possessed of a certain timeliness, speaking to the idiosyncratically temporal nature of our contemporary crisis. This article seeks to historicise the contemporary deluge of maritime imagery, drawing out its connections with the proliferation of the sea image in earlier representational regimes.

Résumé: Nous sommes aujourd’hui inondés d’images de la mer, les représentations maritimes du commerce mondial, de la crise des réfugiés et du …

Utilizing Emergency Management Audio Messages For Traffic Incident Management Performance Measures, Christopher Gartner, Vihaan Vajpayee, Jairaj Desai, Darcy M. Bullock

JTRP Technical Reports

Timely and accurate information regarding roadway incidents is critical for Traffic Management Centers (TMCs) to maintain safety and mobility. While Intelligent Transportation Systems (ITS) cameras and crowdsourced data provide significant visibility, rural interstate corridors often suffer from coverage gaps, or "blind spots," where incidents go undetected until significant queuing occurs. Public safety radio communications serve as the primary coordination method for first responders, creating a "verbal infrastructure" that contains vital information regarding incident location and severity. This study evaluates the feasibility of using Automatic Speech Recognition (ASR) to bridge these gaps by monitoring and analyzing radio traffic. The project developed …

Exploring The Role Of Dialogue In Student Development And Knowledge Generation, Alison Warren

Indiana STEM Education Conference

In classrooms where students are given the space to engage in dialogue, ask questions, and negotiate ideas, science learning comes to life. Providing opportunities for students to negotiate ideas publicly, through dialogue, then privately, through writing has the potential to maximize student idea generation. Although dialogue is widely recognized as important for engagement and communicating ideas, it has also been framed as an epistemic tool. However, the role of dialogue as a sense-making process or epistemic tool, and its relationship to other forms of language, remains under-explored. This study addresses this gap by investigating the role of dialogue and how …

More Than A Design Task: How Questions Shape Student Attention And Learning, Isaiah Kent-Schneider

Indiana STEM Education Conference

Incorporating engineering design activities into education has the potential to transform learning and students' educational experiences. However, when teachers implement engineering design without asking purposeful questions to focus students' attention, students tend to focus on the task but miss out on the intended learning of underlying science and math concepts. This research brief provides practical examples of questions teachers can use to focus student attention during engineering design activities.

Engaging Transnational Writing Assets In The Writing Center: New Pedagogical Directions For Supporting International Multilingual Students, Olalekan T. Adepoju

The Writing Center Journal

This article argues for a shift in writing center pedagogy toward prioritizing transnational writing assets as the basis of our work with international multilingual writers specifically and every writer we encounter generally. While writing center scholarship has paid attention to the influences of language, cultural and rhetorical differences among native and non-native English speakers/ tutors in the writing center, much of this discussion has taken the “comparative” route rather than a “trans-d” (transnational) route with potentials to transform our engagements with scholars, students, and writers from other parts of the world. This IRB-approved research reveals that international multilingual writers possess …

The Loss Function Of Usda Forecasters: Evidence From Wasde Animal Product Price Forecasts, Chad Fiechter, Siddhartha S. Bora, Todd H. Kuethe

Department of Agricultural Economics Faculty Publications

The loss function is a mathematical representation of the costs experienced by a forecaster when observed outcomes differ from what was predicted. Prior studies suggest that USDA forecasts are not optimal based on an assumed mean-zero quadratic loss function. This study proposes an alternative view of forecast evaluation, which assumes all USDA forecasts are produced to minimize the forecasters’ costs, and searches for the dimensions of the loss function under which optimality holds. We illustrate the degree to which USDA loss functions vary across a series of WASDE price forecasts. A better understanding of USDA forecasters’ costs will benefit forecasters …

Application Of Reinforcement Learning To Precision Aerial Delivery System Control In Adverse Wind Conditions, Radman Zarbock

The Journal of Purdue Undergraduate Research

Precision aerial delivery systems (PADS) are a subset of airdropped parachute-leveraging package delivery systems that use autonomous guidance, navigation, and control (GNC) to reach targets with high degrees of accuracy. This technology emerged in the 1990s, and strides have been made since to improve the reliability of traditional physics-based controllers that guide PADS. However, these algorithms still struggle to deliver acceptable performance results when PADS are subjected to austere operating environments, such as those with unpredictable wind. Building on a foundational study in 2022 that used artificial intelligence (AI) and machine learning to improve PADS GNC performance, this study aims …

If You Don’T Know, Now You Know: Jase Special Issue On Hip-Hop Pedagogy For Students With Disabilities (Side A), Jonte C. Taylor

Journal of the Arts and Special Education

This special issue examines Hip-Hop pedagogy (HHP) as a culturally grounded, multimodal approach that supports K–12 students with disabilities. Hip-Hop is presented as a comprehensive culture rooted in the five elements—MCing, DJing, breakdance, graffiti, and knowledge—which offer inclusive pathways for identity development, community, and learning. This special issue of JASE highlights HHP as an asset-based framework that enhances engagement, self-expression, assessment, and social-emotional growth while aligning with high-leverage practices. Research demonstrates that hip-hop–infused instruction can deepen academic understanding, reframe behavioral challenges, and promote equitable, disability-affirming learning environments. The included articles explore belonging for students who stutter, integrated pedagogical models, mentorship …

Keeping It Real: Hip-Hop Based Education In A Mathematics Classroom, Michelle J. Cook, Elizabeth M. Hughes, Jonte C. Taylor

Journal of the Arts and Special Education

Hip-Hop based education (HHBE) infuses elements of Hip-Hop culture into teaching and learning. Growing research shows that HHBE engages students, validates students’ identities and lived experiences, and supports academic success. In this article we share how HHBE can be used in mathematics with a focus on teaching word problem solving strategies. Using vignettes and real-life examples, we illustrate how creative elements of Hip-Hop (i.e., breakdancing, graffiti art, DJing, MCing, knowledge of self) naturally enhance mathematics and word-problem solving instruction. Educators can sample/adapt strategies shared to create HHBE lessons to meet the interests of their students with disabilities. We hope that …

I Am Mentorship: Hip-Hop As A Mirror For Belonging And Becoming, David J. Berg

Journal of the Arts and Special Education

This paper presents MENTEE-SS (Mentorship, Engagement, Nurturing, Trust, Empowerment, Excellence-Systems of Support for Students and Families), a practitioner-focused reimagination of Multi-Tiered Systems of Support (MTSS) through the lens of hip-hop pedagogy, mentorship, and culturally sustaining practices. While traditional MTSS frameworks often emphasize compliance and deficit-based intervention, MENTEE-SS situates support in student identity, creativity, and voice.

Grounded in relational trust and arts integration, the framework uses the author’s original song I’M HIM as a case study in identity reclamation. Three tiers bring this vision to life: co-designed classroom rituals (Yo DJ, Spin That Class!, Tier 1), lyric-writing groups for recovery (The …
