Mapping Responsible Workflows For Geospatial Data Science: Developing The I-Guide Data Ethics Toolkit, Peter T. Darch, Kyra M. Abrams, Ivan Y M Kong

I-GUIDE Forum

AI workflows in geospatial data science offer significant societal benefits but raise ethical, transparency, and reproducibility challenges. Current ethical frameworks and tools are often hard to integrate into daily research practice. This paper introduces the I-GUIDE Data Ethics Toolkit (DET), a lightweight suite designed for users of the NSF-funded Institute for Geospatial Understanding through an Integrative Discovery Environment (I-GUIDE). Based on a longitudinal mixed-methods study, including surveys, interviews, and observations, we identified five design priorities: usability, anticipatory planning, distributed responsibility, comprehensive coverage, and policy compliance. We integrated existing AI and data research lifecycles into an eight-stage I-GUIDE Research Lifecycle, serving …

Evaluating The Evaluation Matrices: Integrating Spatial Assessment In Geospatial Ai Model Training And Evaluation, Fangzheng Lyu

I-GUIDE Forum

This paper examines the limitations of current evaluation metrics in GeoAI. Through two case studies on deep learning models—a building detection classification problem and a remote sensing image fusion regression problem—this paper demonstrates how traditional statistical evaluation matrices alone can be misleading in geospatial problems. The findings indicate that traditional metrics (e.g., RMSE, MAE) used in current GeoAI models can have difficulty capturing the spatial dimensions inherent to geospatial problems. This paper suggests that the model evaluation process in GeoAI should move beyond traditional evaluation matrices by integrating spatial thinking throughout the modeling pipeline—not only incorporating spatial accuracy in model …

Expanding Access To Cybergis-Compute Through Support For Heterogeneous Workflows, Alexander C. Michels, Ian Zhang, Anand Padmanabhan, John Speaks, Rebecca Vandewalle, Shaowen Wang

Assessing Vulnerabilities Associated With High-Risk Dams In Utah, Courtney Flint Dr., Michael Englert, Upmanu Lall Dr.

I-GUIDE Forum

Across the United States, the age of dam infrastructure presents a substantial threat. The potential for structural failure associated with these aging dams is exacerbated by increased climate uncertainty and the threat of dam overtopping due to extreme and prolonged precipitation events. These compound threats place downstream areas at pronounced risk. These downstream areas vary widely. Some are relatively free of vulnerable elements, while others have a complex mix of infrastructure, populations, and ecologically important elements. This paper highlights the risk situation associated with aging dams and hydroclimatic extremes, the methodological and geospatial challenges and opportunities associated with mapping the …

Exploring Dynamic Human Mobility Of Diverse Social Groups Under Heat Conditions: A Simulation-Based Approach, Xin Gu, Su Yeon Han, Soe Win Myint, Eunsang Cho, Yuanhui Zhu, Joonseok Kim

I-GUIDE Forum

Extreme heat events, exacerbated by climate change, present significant risks to human health and disproportionately affect vulnerable populations. Traditional assessments of heat exposure often rely on static residential data, which fails to account for the dynamic human mobility pattern of the population in space and time. Recent work utilizes mobility data to explore exposure dynamics in heat-related studies. However, these studies are primarily focused on the general population or the differences in human mobility across varying income levels in response to heat exposure. Unlike previous studies, this research employs a Monte Carlo simulation that integrates mobility data with American Community …

Tomato Seedling Performance In Five Commercial Organic Growing Media With And Without Supplemental Fertilizer, Elizabeth Maynard, Wenjing Guan, Petrus Langenhoven, Lori A. Hoagland

Department of Horticulture & Landscape Architecture Faculty Publications

Commercially available growing media permitted for use in certified organic production differ substantially in quantity and availability of essential macronutrients. Nutrient availability from fertilizers applied during production will depend on chemical, biological, and physical characteristics of both media and fertilizers; therefore, best practices for fertilizing seedlings are likely to differ. This study evaluated tomato (Solanum lycopersicum L.) emergence, seedling growth, and posttransplant performance when grown in five organic growing media with and without supplemental fertilizer during transplant production in three diverse locations. A 5N–0.88P–3.32K–3Ca (5–2–4) dry fertilizer was tested in all media, and a liquid 3N–0.88P–2.49K (3–2–3) fertilizer was …

Yield And Pungency Of Eight Onion Varieties And Their Response To Sulfur Fertilizer On Fine-Textured Soil, Charlie Rohwer, Jesen Hosch, Brianna Hayward, Cindy Tong

Midwest Vegetable Trial Reports

Onions are notable for their pungency, caused by sulfur-containing compounds. Fine-textured soils high in organic matter, or soils fertilized with organic amendments, are unlikely to require additional sulfur for maximum onion yield. We were interested in the impacts of additional sulfur (in such a situation, unlikely to be sulfur-limited) on pungency, soluble solids, and yield in eight onion varieties. We carried out a study in 2024 in southern Minnesota, designed as a split-plot (onion variety as the whole-plot) with four replicates. Heavy rainfall caused substantial unmarketability in our trial, with ‘Ringmaster’ suffering the most loss (11% of planted ‘Ringmaster’ were …

Disentangling The Channels Of Impact Of The Ukraine War On Global Food Markets: An Integrated Scenario Approach, Maksym Chepeliev, Maryla Maliszewska, Maria Filipa Seara E Pereira

Department of Agricultural Economics Faculty Publications

The war in Ukraine has major implications for the world's agricultural and food markets, as the Black Sea region is a large supplier of crops and fertilizers. Impacts of the war are further exacerbated by the sanctions against Russia, spillover effects from disruptions of other commodity markets, adverse weather events and domestic policies that countries around the world have implemented in pursuit of food security. In this paper, using a comprehensive modeling framework, we decompose the impacts across various channels and show that the cumulative effect of the considered indirect spillovers is even more substantial than the direct agricultural supply …

Selective Anti-Tumor And Normal Tissue Sparing Effects Of Flash Radiotherapy In A Simple Algebraic Model Of Radiochemical Kinetics, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

Background: This short paper presents the solution to an open problem in medical physics: how and when FLASH radiotherapy can have a selective anti-tumor effect. FLASH radiotherapy gives a single large dose of ionizing radiation to a cancer patient within a time span of a few milliseconds, unlike conventional radiotherapy which is divided into several dose fractions given weekly, each lasting about 10 minutes. In some animal models FLASH seems to improve tumor cell killing without damaging normal tissues. However, the mechanism of the selective anti-tumor effect remains elusive. Methods: To explore effects of tissue hypoxia in tumors, a model …

On Closed-Form Preintegration For A Class Of Mixed-Invariant Systems In Seₙ(3), Li-Yu Lin, Kartik A. Pant, Benjamin Perseghetti, James Goppert

School of Aeronautics and Astronautics Faculty Publications

A large class of nonlinear systems in engineering and robotics evolves on geometric manifolds, such as fixed-wing aircraft, quadrotors, etc., whose kinematic motion can be described using Lie groups, in particular SEn(3) . The existing techniques involve numerical integration methods such as Runge-Kutta integration to propagate their motion forward in time. However, these methods are approximate solutions and do not respect the geometric constraints of the nonlinear differential equation, leading to higher computational costs and numerical integration errors. To this end, we propose a geometric closed-form approach to solve the initial value problem for a class of nonlinear systems that …

Safe Human–Robot Collaboration With Risk Tunable Control Barrier Functions, Vipul K. Sharma, Pokuang Zhou, Zhengtong Xu, Yu She, S. Sivaranjani

School of Industrial Engineering Faculty Publications

In this article, we consider the problem of guaranteeing safety constraint satisfaction in human–robot collaboration (HRC) with uncertain human position. We pose this problem as a chance-constrained problem with safety (chance) constraints represented by uncertain control barrier functions, where the probability of safety constraint satisfaction under uncertainty is bounded by a tunable user-defined risk. We solve this stochastic optimization problem using a sampling-based approach and obtain a risk-tunable controller to safely accomplish HRC tasks. We demonstrate the safety and performance of this approach through both simulation and hardware experiments on a 7 degree-of-freedom Franka–Panda manipulator and characterize the tradeoff between …

Research Brief – The Abcs Of Learning The Abcs, Catherine Mcbride, Jennifer Schumaker

Science of Reading

Mastering the alphabet is a foundational step in learning to read; yet not all letters are equally easy for children to learn. This research brief explores the cognitive and perceptual factors that influence letter name and sound acquisition, including familiarity through personal relevance (e.g., letters in a child’s name), visual distinctiveness, memory accessibility, and confusability. It also examines how phonological characteristics of letter names affect sound learning, highlighting the fact that letters whose names begin with their sounds (e.g., B, D) are easier to learn than those with no phonetic connection (e.g., W, Q). Practical recommendations are offered for educators …

Crafting Literary Haiku: Inspiration, Aesthetics, And Season Words, John J. Han

KAUPA Letters
