Human Capital And Lifetime Income Gains Of Scaling-Up Small-Quantity Lipid Nutrient Supplements Among Children Under 2 Years: A Modelling Analysis, Nandita Perumal Phd, Goodrarz Danaei, Günther Fink, Mark Lambiris, Christopher R. Sudfeld

Faculty Publications

Undernutrition in early childhood is associated with adverse health and developmental outcomes later in life and remains a persistent global public health problem. Providing small-quantity lipid nutrient supplements (SQ-LNS) to children aged 6-24 months improves child growth and neurodevelopmental outcomes, but the potential long-term benefits to human capital have not been previously estimated. We estimated the potential returns to schooling and lifetime income attributable to increasing coverage of SQ-LNS for children < 2 years of age from 0% to 50% or 90% per five-year birth cohort in five countries (Bangladesh, Burkina Faso, Ethiopia, Pakistan, and Uganda) with a high burden of undernutrition. Random-effects meta-analyses were used to estimate the effect of SQ-LNS on child development using evidence from randomized controlled trials, and to estimate the returns to lifetime income as a function of change in development based on a de novo meta-analysis of observational economic studies. Gains in school years attributable to scaling-up SQ-LNS to 90% coverage ranged from 0.14 million school years (95% uncertainty interval [UI]: 0.064, …

Anchoring ‘Neo-Hahnian Outdoor Education’ In The Cold War Era: A History Of Character Building In The Outward Bound Movement, Jayson Seaman

Faculty Publications

The invitation to comment on a foundational early article from the JAEOL provided a welcome opportunity to engage with Andrew Brookes’s trilogy of ‘neo-Hahnian outdoor education’ critiques (Brookes, 2003a, 2003b, 2023). In this article, I approach outdoor education’s character building ideology by using archival and secondary sources to situate its evolution in four periods corresponding with major geopolitical and cultural movements: (1) 1941–1945 when Outward Bound (OB) was established; (2) 1946–1952 when Hahn exported OB from his perch at Gordonstoun; (3) 1953–1967 when OB expanded to the U.S. and replicated globally, and (4) 1968–1976 when human potentialism replaced muscular Christianity …

Assessing The Tax Communications Of E-Commerce Vendors, Part I, David Gamage

Faculty Publications

This article reports research results from a study analyzing the tax communication practices of top e-commerce retailers and marketplaces. The research found a spectrum of tax communication practices. Notably, many (but not all) e-commerce businesses that did not collect sales tax did still inform customers about potential use tax obligations, though the transparency of this information varied.

Displaced Decarbonization: Climate Necropolitics And The Contested Spatialities Of Green Hydrogen In Namibia, Meredith J. Deboom

Faculty Publications

Green hydrogen is often presented as a transformative solution to the dual challenges of decarbonization and economic development. This article applies the framework of climate necropolitics to interrogate the contested spatialities underlying such “win-win” narratives. It does so through an extended case study of Hyphen Hydrogen Energy, a $10 billion green hydrogen project planned for Lüderitz, Namibia. A remote town of 20,000 in a country with a $12 billion annual GDP, Lüderitz initially appears to be an unlikely host site for the “industrial fuel of the future.” To explain this outcome, I first illustrate how discordant socio-spatial projects—including European energy …

Explaining Youth Driver Licensing Determinants Using Xgboost And Shap, Kailai Wang, Jonas De Vos, Michael Smart, Sicheng Wang

Faculty Publications

This study explores the factors influencing driver's license acquisition among young individuals and examines its broader implications for mobility, safety, and sustainability. Leveraging nationally representative survey data on Millennials and Generation Z, we apply eXtreme Gradient Boosting (XGBoost) and SHapley Additive Explanations (SHAP) to identify key socioeconomic determinants of teenage driver's license attainment. Our findings reveal consistent predictors across both generations, including the percentage of licensed family members, household income per capita, educational attainment, and public transit ridership. We identify meaningful dose-response relationships, such as the increasing influence of licensed household members beyond a 0.75 threshold and the …

A Survey Of Sampling Methods For Hyperspectral Remote Sensing: Addressing Bias Induced By Random Sampling, Kevin T. Decker, Brett J. Borghetti

Faculty Publications

Identified as early as 2000, the challenges involved in developing and assessing remote sensing models with small datasets remain, with one key issue persisting: the misuse of random sampling to generate training and testing data. This practice often introduces a high degree of correlation between the sets, leading to an overestimation of model generalizability. Despite the early recognition of this problem, few researchers have investigated its nuances or developed effective sampling techniques to address it. Our survey highlights that mitigation strategies to reduce this bias remain underutilized in practice, distorting the interpretation and comparison of results across the field. In …

A Reliable And Efficient Detection Pipeline For Rodent Ultrasonic Vocalizations, Sabah Shahnoor Anis, Devin Mark Kellis, Kris Ford Kaigler, Marlene A. Wilson, Christian O'Reilly

Faculty Publications

Analyzing ultrasonic vocalizations (USVs) is crucial for understanding rodents' affective states and social behaviors, but the manual analysis is time-consuming and prone to errors. Automated USV detection systems have been developed to address these challenges. Yet, these systems often rely on machine learning and fail to generalize effectively to new datasets. To tackle these shortcomings, we introduce ContourUSV, an efficient automated system for detecting USVs from audio recordings. Our pipeline includes spectrogram generation, cleaning, pre-processing, contour detection, post-processing, and evaluation against manual annotations. To ensure robustness and reliability, we compared ContourUSV with three state-of-the-art systems using an existing open-access USV …

Actor–Partner Model Of Parenting And Co-Parenting Practices And Youth Resilience During The Covid-19 Pandemic, Olivia Aspiras, Jaimie O'Gara, Justine Radunzel

Faculty Publications

The present research examined parents' perspectives of co-parenting and supportive and hostile parenting as predictors of youth resilience during the COVID-19 pandemic. Participants were 47 mother/father dyads who had at least one K-12 child (Mage = 11.40, SD = 3.92). Mothers and fathers each completed an online survey that measured parenting, co-parenting, and youth resilience during the pandemic. Data were analyzed using the actor–partner interdependence model. Results revealed a positive relationship between mother supportiveness and perceived youth resilience; in contrast, increased father supportiveness was associated with lower perceived youth resilience. For both mothers and fathers, increases in their own hostility …

“They Are Fat And Want Special Treatment For Being Fat”: Backlash To And Lay Theories Of Fat Activism, Flora Blanchette-Oswald, Minh Duc Pham, R. J. Harr, Alexandra Garr-Schultz, Kimberly E. Chaney

Faculty Publications

Fat activism is a movement that seeks to acknowledge and eliminate the oppression of fat people. The movement and those who participate face significant backlash, yet fat activism is understudied. We sought to understand lay theories about fat activism; that is, how everyday people think about the goals and motivations of fat activism, and people who engage in fat activism, to understand how these perceptions shape support for and backlash toward fat activism. In Study 1 (N = 294), we qualitatively elucidated lay theories of fat activism in a US nationally representative sample. We identified lay theories that both …

Wind-Resilient Solar: Harnessing Cfd For Enhanced Load Estimation, Aly Mousaad Aly

Faculty Publications

Solar panels are a cornerstone of renewable energy infrastructure, playing a pivotal role in global sustainability efforts. To ensure their resilience and long-term viability, accurate wind load estimations are essential for designing supporting structures, which account for nearly 50% of their total cost. However, traditional building codes lack comprehensive guidance for solar panels, resulting in inconsistent estimations due to discrepancies in scaled wall-bounded wind tunnel testing methodologies. These inaccuracies pose safety risks, increase costs, and hinder adoption. Emerging technologies like computational fluid dynamics (CFD) simulations offer a promising alternative by enabling full-scale analysis under realistic conditions of complete turbulence. This …

Eddy, Cheryl Harrison, Olivier Maury, Kelly Ortega-Cisneros, Colleen M. Petrik, Derek P. Tittensor, Ryan F. Heneghan

Faculty Publications

Understanding climate change impacts on global marine ecosystems and fisheries requires complex marine ecosystem models, forced by global climate projections, that can robustly detect and project changes. The Fisheries and Marine Ecosystems Model Intercomparison Project (FishMIP) uses an ensemble modeling approach to fill this crucial gap. Yet FishMIP does not have a standardised skill assessment framework to quantify the ability of member models to reproduce past observations and to guide model improvement. In this study, we apply a comprehensive model skill assessment framework to a subset of global FishMIP models that produce historical fisheries catches. We consider a suite of …

Rps Coach Is Biased - And Proud Of It, John Lande

Faculty Publications

This short essay explores the concept of bias in artificial intelligence tools used in dispute resolution. Biases are not necessarily flaws to be avoided, but inevitable and potentially constructive features of these tools. They reflect values and design choices that AI developers should disclose.

There are both market and ethical imperatives for AI tools to disclose their features and embedded values. As developers compete for users, people will want to know what they’re getting. Disclosure helps users understand the effects of assumptions, priorities, and frameworks built into a tool’s design, and thus should be treated as a core ethical principle. …

Government-Backed Insurance For Artificial Intelligence Technologies, Renee Henson

Faculty Publications

Artificial intelligence (AI) is an unpredictable technology that has the capacity to both help and harm people. Although insurance plays a key role in compensating for harms in other contexts, AI-produced damages evade traditional principles of risk pricing which limits viable commercial insurance coverage. AI requires modified insurance systems that can compensate diverse and unpredictable losses. Just like AI, at one time nuclear energy was viewed as a new and profitable, yet wholly unpredictable, technology that had the capacity to cause devastating harm. AI poses similar threats to society in certain domains, including, for example, health care (e.g., risk management …

Examining Whether Method Of Suicide Exposure And Closeness To Decedent Relate To Firearm Storage Practices, Evan A. Albury, Jessica L. Gerner, David A. Jobes, Raymond P. Tucker

Faculty Publications

Introduction: One factor that can influence whether someone will engage in secure firearm storage is having a suicide exposure (SE). Daruwala et al. (2018) examined this and found that individuals with an SE, without considering perceived closeness, did not significantly differ from those who did not have an SE in their firearm storage practices. Thus, the present study aimed to replicate and extend the research of Daruwala et al. (2018) by examining if the method of suicide (by firearm or other means) and closeness of suicide decedent relate to secure firearm storage practices. Methods: 308 male firearm owners completed self-report …

Exact Inference For Transformed Large-Scale Varying Coefficient Models With Applications, Tianyu Chen, Robert Habans, Thomas Douthat, Jenna Losh, Lida Chalangar Jalili Dehkharghani, Li Hsiang Lin

Faculty Publications

Studying migration patterns driven by extreme environmental events is crucial for building a sustainable society and stable economy. Motivated by a real dataset about human migrations, this paper develops a transformed varying coefficient model for origin and destination (OD) regression to elucidate the complex associations of migration patterns with spatio-temporal dependencies and socioeconomic factors. Existing studies often overlook the dynamic effects of these factors in OD regression. Furthermore, with the increasing ease of collecting OD data, the scale of current OD regression data is typically large, necessitating the development of methods for efficiently fitting large-scale migration data. We address the …

Do Analysts’ Gross Margin Forecasts Influence Manager's Decisions To Recognize Inventory Losses?, Nusrat Jahan, Padmakumar Sivadasan

Faculty Publications

Accounting standards require firms to write down their inventory when its market value (or net realizable value) drops below cost. Recognizing inventory write-downs decreases gross margins and increases scrutiny of managers’ inventory management practices. Further, it is difficult for market participants to assess inventory balances. Therefore, managers often delay recognizing inventory losses. Compared with other analysts, analysts who issue disaggregated gross margin (GM) forecasts evaluate a firm's inventories more closely, which should motivate managers to recognize expected inventory losses. Consistent with this prediction, managers’ likelihood of recognizing an expected inventory loss increases as more analysts provide GM forecasts. However, the …
