Evaluation Of Aggregate Gradation Specifications And The Feasibility Of Harmonization With Aashto Standards, Husam Elgaali, Ayesha Shah, Jan Olek

JTRP Technical Reports

The aggregate gradations specified by the Indiana Department of Transportation (INDOT) differ from those of the American Association of State Highway and Transportation Officials (AASHTO). Preliminary discussions suggest that adopting AASHTO standard gradation sizes could provide national alignment and simplify production for those operating in multiple states and supplying projects not subject to INDOT specifications. A comprehensive study was performed to evaluate the current INDOT specifications for coarse and fine aggregate gradations and to assess the potential impacts and feasibility of adopting AASHTO-specified gradations. A comparative analysis of INDOT gradations against AASHTO, ASTM International (ASTM), and those of neighboring states …

Implementation Study For In-Place Testing Of Asphalt Treated Cold Recycled Pavements, Pablo Orosa Iglesias, Cheng Zhang, Daniel Mauricio Santamaria, John E. Hadddock

JTRP Technical Reports

This study evaluated the feasibility of rapid in-situ strength test methods for asphalt-treated cold recycled (ATCR) pavements in Indiana, with a secondary objective of characterizing the dynamic modulus of a locally produced ATCR mixture for use as AASHTOWare Pavement ME Design inputs. The long-pin shear test (LPST) and short-pin raveling test (SPRT), developed through National Cooperative Highway Research Program (NCHRP) Project 09-62, were evaluated on a cold in-place recycling (CIR) project on SR 13 in Greenfield, Indiana. Field results for blow counts exceeded the proposed NCHRP threshold moments after compaction, with torque values approaching but not yet reaching the NCHRP …

Simulating Current And Future Ev Growth Scenarios In Indiana, Omar Faruqe Hamim, Xiaowei Chen, Kenny Chandra Wijaya, Lavan Teja Burra, Zengxiang Lei, Rajat Verma, Konstantina (Nadia) Gkritza, Satish Ukkusuri

JTRP Technical Reports

As Indiana transitions toward electric mobility, data-driven planning is essential to guide electric vehicle (EV) charging infrastructure investment and deployment. This study evaluates the current and future performance of Indiana’s EV charging infrastructure using Multimodal Energy-Efficient Trip Simulation in Real Time (METS-R), a high-resolution simulation platform. Five EV adoption scenarios, ranging from pessimistic to optimistic, are modeled for the years 2024 through 2031, to assess spatial and temporal variations in public charging demand. Results reveal increasing public charging demand under high adoption scenarios, with significant disparities between urban and non-urban areas. Accessibility to public charging is found to be uneven …

Why Repeat Visitors Matter For Harassment‑Prone Destinations: Five Actionable Lessons For Accommodation Managers, Annmarie Nicely

Visitor Harassment Research Unit Special Papers

The goal of the study was to identify demographic factors that could predict visitors likely to support micro-traders at a destination after being harassed by a member of their community. Then show how the accommodations sector (like hotel managers and vacation home rental managers) can use the findings to improve visitor support of micro-traders at destinations with trader harassment (TH). The researcher examined seven demographic features of visitors to four countries. They were their gender, education level, income level, marital status, prior visit to the destination, type – domestic or international, and whether they were alone at the time of …

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 …

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. …

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 …

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 …

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 …

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 …

“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.

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 …

Developing And Implementing A Primary Source Literacy Case Scenario For The Undergraduate Business Classroom, Annette Bochenek, Megan Troyer

Libraries Faculty and Staff Scholarship and Research

This article discusses the development and implementation of a case-based learning scenario activity intended to enhance primary source literacy among undergraduate business students. The activity was delivered in the context of a large Midwestern university’s undergraduate business course. This case is based on the ACRL RBMS-SAA Guidelines for Primary Source Literacy and gives students an opportunity to use digitized primary archival sources as part of the research process in connection with a modern business-related scenario in which they can apply primary source literacy skills. This guided activity also explores affective experiences as they occurred in student responses to this activity …

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

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, …

Pumpkin Variety Demonstration In West Michigan, 2025, Benjamin P. Werling, Justin Adams

Midwest Vegetable Trial Reports

Pumpkin variety demonstrations were conducted in 2025 at the West Central Michigan Research and Extension Center in Hart, MI, to compare yield, size class, and irrigation response among 21 pumpkin varieties representing jack-o’-lantern, large carving, and decorative cultivars. Demonstration plots were established on sandy soil under standard commercial fertility, pest management, and weed control practices. To assess irrigation effects under dry conditions, approximately 60% of each plot received supplemental sprinkler irrigation.

Jack-o’-lantern varieties varied in size distribution, with some producing a mix of 60, 45, and 30–35 count fruit with few larger-sized pumpkins. Others skewed toward larger bin count classes. …
