Design And Evaluation Of A Collaborative Xr Framework With Abstract Building Blocks For Manufacturing System Prototyping, Shaun Macdonald, Bixun Chen, Yuanjie Xia, Rami Ghannam

School of Engineering Technology Faculty Publications

Manufacturing systems are complex installations designed and developed by stakeholders with differing expertise. However, system design primarily features traditional methods, long lead times, and siloed environments, which obstruct comprehension, communication, or collaboration. Prior research has used extended reality (XR) to prototype and visualise specific manufacturing applications; however, flexible system modelling remains complex. To address these issues and lay the foundation for future-facing manufacturing design as part of Industry 4.0, we introduce ARTIFY—a prototype XR framework for conceptual system prototyping. It features abstract building blocks that can be semantically reconfigured to support early-stage modelling of varied manufacturing systems in immersive environments. …

Artificial Intelligence In Literacy Education, Megan V. Gierka, Timothy N. Odegard

Science of Reading

Artificial intelligence tools are entering K–12 literacy classrooms at an unprecedented rate, yet most have not undergone independent validation.

How Teachers Can Apply Learning Theories To The Five Pillars Of The Science Of Reading, Jennifer Renn

Science of Reading

This brief provides an introduction to six learning theories and guidance on how they can be used to teach the pillars of the science of reading (SOR). Because SOR is rooted in a broad range of interdisciplinary research and covers several key competencies, classroom teachers may be overwhelmed and uncertain of how to best meet students’ needs. There is also a tendency to use instructional strategies and techniques that include student repetition and recognition of information. While these approaches can help students learn to read and write, teachers should consider using a range of learning theories to better align instruction …

A Reflection On What Pharmacists In Different Countries Can Learn From One Another, Aaryaman Khurana, Patricia Darbishire

Purdue Journal of Service-Learning and International Engagement

What would be the first words that come to mind if you were asked about the US health care system? I asked that question to several of my friends and pharmacy peers and received mixed responses such as “expensive,” “confusing,” “hard to navigate,” and “best in the world.” This was not surprising considering the many options and the varying quality of medical procedures, medical devices, and pharmaceuticals available. I wondered how responses might differ if I posed the same question about their health care to those in a third-world country. So, I asked the same question of friends and family …

Stocks And Shocks: Assessing The Relative Roles Of Public And Private Inventories In Buffering Rice Price Volatility In The Philippines, Bernhard Dalheimer, Kenneth Foster, Gerald E. Shively, Valerien O. Pede, Dela-Dem Doe Fiankor, Jacob Ricker-Gilbert, Pratibha Bist

Department of Agricultural Economics Faculty Publications

Public stockholding of food is politically contentious and economically challenging. Although private stocks are generally understood to be more efficient than public stocks at providing a reliable buffer against production shortfalls, private stocks often fail to stabilize prices during extreme food market shocks. Moreover, maintaining large public stock programs in which the government acts as the buyer or seller of last resort, can be very costly. This paper analyzes the recent historical success of public and private rice stocks in stabilizing domestic rice prices in the Philippines, the world’s largest net importer of rice. Relying on competitive storage theory and …

Vander Woude, Steven Cook, Bukola Usidame, Megan E. Patrick, Michael R. Elliott, James F. Thrasher, Nancy L. Fleischer

Department of Health and Kinesiology Faculty Publications

Purpose

We examined whether workplace and hospitality vape-free air law (VAL) population coverage was associated with adolescent e-cigarette use and related disparities in the United States.

Methods

We analyzed associations between county-level workplace and hospitality VAL coverage (100% vs. < 100%) and current e-cigarette use (2014–2022) and first e-cigarette initiation (2015–2022) among US 8th, 10th, and 12th graders using nationally representative, cross-sectional Monitoring the Future data. We implemented weighted, grade-stratified, modified Poisson regression models, adjusted for individual-, county-, and state-level confounding factors, examining disparities by sex, race and ethnicity, parental education, and college educational expectations through two-way interactions.

Results

Workplace and hospitality VAL coverage was not associated with adolescent e-cigarette use or initiation overall. However, we did find that VAL coverage was associated with lower current e-cigarette use in some sociodemographic subgroups. Full (100%) hospitality VAL coverage was linked to lower e-cigarette use among male 8th and 12th graders, 12th graders with parents without a bachelor's degree, Hispanic 8th …
