Centering Ai Literacy: Exploring Brazilian International Students’ Perceptions Of Chatgpt And Peer Tutoring, Leigh Ann Dunning, Raissa Borges De Oliveira Leal
The Writing Center Journal
For English as an Additional Language (EAL) students, generative AI (GenAI) offers meaningful support for writing in English, while also introducing a new set of challenges. Supporting EAL students in developing AI literacy is crucial to their growth as confident, adaptable writers, and writing center tutors are uniquely positioned to facilitate this development. This case study explores the experiences of undergraduate Brazilian international students at a small liberal arts college who received writing feedback from both peer writing center tutors and ChatGPT. Findings indicate that students valued the human connection, contextual understanding, and rhetorical support offered by peer tutors, while …
Attending To Present Others: A Framework For Supporting Multilingual Graduate Writers, María P. Carvajal Regidor, Allison Kranek
Attending To Present Others: A Framework For Supporting Multilingual Graduate Writers, María P. Carvajal Regidor, Allison Kranek
The Writing Center Journal
Extending prior work on present others, individuals who are not physically present in writing center sessions—such as advisors, colleagues, and peers—but who directly or indirectly impact what happens during consultations (Kranek & Carvajal Regidor, 2021), we argue that attending to present others is one way to more holistically support multilingual graduate writers. Based on data from session recordings, we contend that present others can be used as a framework to train consultants to better address the specific needs of this student population by acknowledging their socialization processes, feedback networks, language needs, and emotions. Then, we share two approaches to consultant …
Reimagining Wpa And Writing Center Administration Centering Minority Writers, Saurabh Anand
Reimagining Wpa And Writing Center Administration Centering Minority Writers, Saurabh Anand
The Writing Center Journal
This piece explores the discussions surrounding multilingualism, internationalization, and queerness within writing center studies (WCS). As a branch of writing program administration (WPA), this piece situates above-disciplinary conversations in relation to second language studies (SLS) and broader language and literacy education scholarship to identify areas where disciplinary collaboration and attention are still needed, particularly around questions of professional development, administrative strategies, and pedagogies supporting multilingual writers in writing center spaces. This piece begins by reviewing the major trends, contributions, and key terms in existing literature centering on multilingual writers and SLS to identify ways and areas of collaboration and disciplinary …

From “Contact Zone” To “Collaborative Zone”: Multilingual Writers’ Tensions And Opportunities In The Writing Center, Qianqian Zhang-Wu, Isabelle M. Lundin, Neal Lerner
From “Contact Zone” To “Collaborative Zone”: Multilingual Writers’ Tensions And Opportunities In The Writing Center, Qianqian Zhang-Wu, Isabelle M. Lundin, Neal Lerner
The Writing Center Journal
Writing center scholars have adopted Pratt’s (1991) “contact zone” metaphor to describe the diversity of consultants and students in writing centers, but this literature has largely overlooked the perspectives of multilingual students. Through surveys, interviews, and session data, we found that while multilingual students described rich linguistic identities, they also experienced tension and instability as language users. Students often framed their considerable language assets as deficiencies in academic writing contexts. They faced additional tension between instructor expectations and their own understanding of assignment goals. Students frequently sought native-like language competency from consultants and expected them to serve as informants about …
“Dear Colleague”: Upholding Multilingual Voices And Pedagogies In Writing Centers Against Flattening Forces, Melanie Mcnulty, Amina Selimaj
“Dear Colleague”: Upholding Multilingual Voices And Pedagogies In Writing Centers Against Flattening Forces, Melanie Mcnulty, Amina Selimaj
The Writing Center Journal
Drawing on the dual perspectives of a writing center administrator and a tutor, this paper explores how political symbolism—such as the Department of Education’s 2025 “Dear Colleague” letter—technological homogenization, and institutional consolidation are contributing to a resurgence of standard language ideology and attempting to erode linguistic diversity. We argue that writing center administrators and tutors must confront their own biases, reflect on their positionality, and adopt pedagogies that prioritize inclusion and agency over assimilation; and must refuse these pressures that seek to judge diversity as deficit and flatten difference into sameness.
Native-Speakerism And Multilingual Student Anxiety In One-To-One Mentoring, Grace Lee-Amuzie
Native-Speakerism And Multilingual Student Anxiety In One-To-One Mentoring, Grace Lee-Amuzie
The Writing Center Journal
While one-to- one writing tutoring is often viewed as a supportive space for student writers, it can also reproduce racialized linguistic hierarchies that exacerbate anxiety for multilingual students. This article examines second language (L2) anxiety as a structurally induced emotional response to native-speakerism— the ideology that privileges white, Anglophone, native English speakers as the standard for language competence. Drawing from L2 anxiety research in applied linguistics and writing center studies, the article explores how native-speakerism influences multilingual students’ self-perception, interaction, and performance in L2 during one-to- one tutoring. It discusses the sources and dimensions of L2 anxiety across all four …
The Myth Of Revising By Ear: Does It Help Multilingual Writers?, Soo Hyon Kim
The Myth Of Revising By Ear: Does It Help Multilingual Writers?, Soo Hyon Kim
The Writing Center Journal
This study examines what multilingual writers notice while they read their writing aloud, and whether reading aloud helps improve the accuracy of their writing during revision. It also investigates whether multilingual writers’ second language (L2) proficiency influences the extent to which reading aloud impacts revision. To address these questions, a counterbalanced, mixed design study was carried out with two experimental conditions: revising while reading aloud and revising while reading silently. Multilingual writers of higher and lower English proficiency at a large research university participated in a two-day sequence of composition and revision, two times, over the course of two weeks. …
The Loss Function Of Usda Forecasters: Evidence From Wasde Animal Product Price Forecasts, Chad Fiechter, Siddhartha S. Bora, Todd H. Kuethe
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 …
Vibrissae-Inspired Vision-Based Magnetic-Actuated Whisker, Zhixian Hu, Yi Cheng, Juan P. Wachs, Yu She
Vibrissae-Inspired Vision-Based Magnetic-Actuated Whisker, Zhixian Hu, Yi Cheng, Juan P. Wachs, Yu She
School of Industrial Engineering Faculty Publications
Tactile perception is significant for robotic operation in unstructured environments. Whisker-based sensors offer lightweight bio-inspired solutions, yet most rely on single-whisker sensing and are limited by passive interaction and constrained functionality. Here we present a circular array of eight independently actuated whiskers, each driven by a pulse-switchable permanent magnet and tracked by a camera. This design enables simultaneous multi-point sensing and coordinated actuation, supporting diverse functions. Quantitative analyses demonstrate accurate pixel-to-physical mapping, consistent pixel-to-force characterization, and long-term repeatability. In this work, we show that an vibrissae-inspired vision-based magnetic-actuated whisker array integrating distributed perception with active interaction achieves reliable physical mapping, …

Application Of Reinforcement Learning To Precision Aerial Delivery System Control In Adverse Wind Conditions, Radman Zarbock
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 …
Flood Prediction With Sentinel-1 Synthetic Aperture Radar From Hurricane Helene, Jingyu Xiao, Jessica Li
Flood Prediction With Sentinel-1 Synthetic Aperture Radar From Hurricane Helene, Jingyu Xiao, Jessica Li
The Journal of Purdue Undergraduate Research
Floods are the most common natural disaster globally, causing thousands of deaths every year. Timely and accurate flood forecasts are crucial for developing early warning systems, evacuation plans, and effective strategies to enhance community resilience. Soil moisture is an important parameter in flood forecasting. Unfortunately, existing soil moisture sensor networks and optical remote sensing–based techniques for soil moisture estimation lack the spatial resolution needed for accurate flood forecasting. This study presents an approach for flood prediction using Sentinel-1 C-band synthetic aperture radar (SAR) data. SAR offers high spatial resolution and operates day and night under all weather conditions, making it …

Implications Of Noninvasive Blood Pressure Pumps On Mean Arterial Pressure, Sammie Miller
The Journal of Purdue Undergraduate Research
Noninvasive blood pressure pumps are recommended as the primary form of acquiring patient blood pressure to test for blood poisoning. The Philips IntelliVue Patient Monitor MP5, the Philips SureSigns VS4/VS3 Vital Signs Monitor, the Philips EarlyVue VS30 Vital Signs Monitor, the Philips IntelliVue Patent Monitor MP2/X2, the Philips IntelliVue Patent Monitor MMS, and the Philips IntelliVue Patent Monitor MP3/X3 were tested for accuracy. The control condition for hypotension was 95/55 (68) mmHg, normal blood pressure was 120/80 (93) mmHg, and hypertension was 155/85 (108) mmHg. The order of values is arrayed according to diastolic, systolic, and mean arterial pressure. The …
From Test Tracks To Carbon Tracks: Evaluating The Carbon Emissions Of Autonomous Vehicle Development, Sarah Deniz
From Test Tracks To Carbon Tracks: Evaluating The Carbon Emissions Of Autonomous Vehicle Development, Sarah Deniz
The Journal of Purdue Undergraduate Research
Autonomous vehicle (AV) development has seen a sharp increase in the past 10 years, and there is a significant energy cost of training AVs to meet safety regulations. The training process includes virtual simulation training as well as physical training on public roads and within private testing facilities. The high energy expenditure associated with AV training has a respective environmental cost that can be quantified as a lifetime “carbon debt” of released carbon emissions. The environmental sustainability of AVs has not been thoroughly studied in currently available literature, and this paper showcases a model that quantifies the total “carbon debt” …

Hip-Hop Culture As A Catalyst For Belonging Among Black Male High School Students Who Stutter, Antonio L. Ellis
Hip-Hop Culture As A Catalyst For Belonging Among Black Male High School Students Who Stutter, Antonio L. Ellis
Journal of the Arts and Special Education
This ethnographic study explores how Hip-Hop culture fosters belonging, identity, and agency among six Black male high school students who stutter in a public charter school in Baltimore, Maryland. Grounded in culturally sustaining pedagogy, DisCrit, and Hip-Hop pedagogy, the research draws on participant observation, interviews, and field notes to examine how students use freestyling, beat-making, and cyphering as expressive tools. Findings reveal that Hip-Hop repositions stuttering as rhythmic expression, cultivates emotional safety through peer collaboration, and challenges deficit-based speech norms. Participants described Hip-Hop spaces as sites of affirmation where their voices were valued and their identities celebrated. The study calls …
Gis Librarians' Involvement In Critical Information Literacy Instruction, Melissa Chomintra, Pete E. Pascuzzi
Gis Librarians' Involvement In Critical Information Literacy Instruction, Melissa Chomintra, Pete E. Pascuzzi
Libraries Faculty and Staff Scholarship and Research
Critical information literacy (CIL) is a theory and practice that considers the sociopolitical dimensions of information and knowledge production. As the field of geospatial information evolves, equipping librarians with the skills to critically engage with geospatial information becomes integral to facilitating informed research, promoting spatial literacy, and strengthening the accessibility of geospatial data for their user communities. To understand geospatial data librarians’ current involvement in CIL, librarians were surveyed to examine if they incorporate CIL into their instruction, how they incorporate CIL into their instruction, and what are the benefits and challenges of doing so. The survey gathered both quantitative …
Dying To Belong? The Impact Of Thwarted Belongingness Among Those Who Attempt Suicide In Jail, Dayana R. Escobedo, Mckenzie Wood
Dying To Belong? The Impact Of Thwarted Belongingness Among Those Who Attempt Suicide In Jail, Dayana R. Escobedo, Mckenzie Wood
The Guardianship Journal
Suicide and attempted suicide remain a major concern in correctional facilities. Jail personnel have developed unique ways of responding to incarcerated individuals who display signs of suicidal ideation, but may be less equipped to identify who may be suicidal upon arrival at the facility. Among potential markers for suicidal behaviors are incarcerated individuals struggling with feelings of thwarted belongingness, or a feeling of disconnection and lack of closeness. Applying a quantitative methodology, this study utilized data obtained from a mid-sized jail in the Mountain West subregion of the Western United States. The data, retrieved from correctional officer reports and intake …
The Equity Dead Zones: Legal Intersectionality Failure Points In Chapter 13 Bankruptcy, Tearria N. Simmons
The Equity Dead Zones: Legal Intersectionality Failure Points In Chapter 13 Bankruptcy, Tearria N. Simmons
The Guardianship Journal
Legal intersectionality failure points describe the systemic fractures that occur where overlapping legal, social, and economic inequalities converge, potentially producing compounded barriers to relief. Each failure point marks a site of marginalization. In what ways do individuals already recognized as vulnerable in Chapter 13 bankruptcy face a heightened risk when multiple forms of disadvantage intersect? When these intersections combine in mutually reinforcing ways—racial, economic, and relational disparities colliding with structural deficiencies in family, property, and bankruptcy law—does it result in pronounced negative outcomes, and, if so, what are those outcomes? Within this convergence, could there be a space where compounded …

Influencing The Meteoric Rise Of Ai: Centering Ethics, Law, And Society In Urgent Policy Reform, Erin L. Shah Mspm, Heath A. Clark Mba, Xarlene B. Choi Bs, Garrett K. Chan Phd
The Guardianship Journal
Artificial intelligence (AI) represents a transformative technological advancement with the potential to yield extraordinary societal benefits while simultaneously introducing significant potential harms to individuals, governments, and society. The adoption of AI has outpaced the ability of society to collectively and cohesively respond through the implementation of adequate regulatory guardrails. While AI presents novel benefits and challenges, the broader dynamic of responding to new, uncharted technologies has historical precedence. The article's methodological approach employed empirical research using law articles and policies. As such, the article explores the benefits, challenges, and actual or potential harms in three business sectors: business and finance, …
Engaging Seminars: The Impact Of Storytelling In Public Safety Education, Mimi Gough, Glenn L. Walton
Engaging Seminars: The Impact Of Storytelling In Public Safety Education, Mimi Gough, Glenn L. Walton
The Guardianship Journal
This paper examines the important role of storytelling in higher education as a technique for engaging students in course content and applies its relationship to the experiential learning theory (ELT) in which learners are actively seeking knowledge through authentic application. Storytelling can be a particularly effective method when used during live online seminars in public safety education, since this particular program of study often relies on verbally communicating realistic and credible information. Sharing various examples of actual encounters can help students better prepare for these types of situations when they face them in their future careers. Incorporating evidence to support …
