LidarBoX: a 3D-printed, Open-source Altimeter System to Improve Photogrammetric Accuracy for off-the-shelf Drones

Creator:: Bierlich, K. C., Wengrove, Drummond, Bird, Clara N., Davidson, Robert, Chandler, Todd, Torres, Leigh G., and Cantor, Mauricio
Abstract:: Drones provide a privileged birds’-eye view for collecting high-resolution imagery formorphometric and behavioral sampling of animals. Biologically meaningful measurements extracted from overhead images require an accurate estimate of altitude, but current commercial drones include inaccurate barometer estimates. Recent proposals for coupling altimeter systems to drones have provided customized, open-source solutions,...

Molded Fiber Bottle Coatings for Environmental Resistance and Sustainability

Creator:: Sim, Elaine
Abstract:: In recent years, non-renewable and non-biodegradable plastic packaging forms the majority of landfilled waste. These products, mainly made from Polyethylene Tetraphlatate (PET) and other polyolefins, have excellent durability and barrier properties, but take hundreds of years to degrade. Much focus has been put on developing environmentally friendly alternatives to polyolefins...

The Examination of Escherichia coli Contamination via Agricultural Water Applications and Survival During Pre-Harvest Field Curing of Dry Bulb Onions

Creator:: Racine, Jason R.
Abstract:: 2020 and 2021 brought the first reported outbreaks of salmonellosis epidemiologically linked to dry bulb onions in the United States. Outbreak investigations were not able to implicate a specific source of the contamination but speculated that contaminated water was a significant contributor. The Produce Safety Rule established minimum standards for...

Generalized Preconditioning to Accelerate Simulations with Large Multiphase Chemical Kinetics Models

Creator:: Walker, Anthony S.
Abstract:: Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...

Corpus-Based Studies on Pregnancy

Creator:: Mullen, Alyson
Abstract:: The pregnancy and postpartum periods are full of major life transitions. So often, the focus of the literature is about the unborn baby and physical changes a woman experiences throughout this timeframe. Many sources often overlook women’s personal experiences in the perinatal period. Despite an increase in perinatal mood and...

From work-first to learn first : navigating educational choices among TANF recipients through the lens of possible selves and stigma

Creator:: Jones, Terese D.
Abstract:: Individuals who are parents and students on TANF experience challenges accessing and persisting in higher education. This study explored the experiences of TANF recipients who are navigating a return to higher education and the impact of college on how they construct a future self. Two theoretical frameworks were used to...

Unoccupied aircraft systems in forest monitoring applications

Creator:: Barker, Matthew I.
Abstract:: In recent years, unoccupied aircraft systems (UAS) have become increasingly affordable and straightforward to incorporate in monitoring applications of forested ecosystems. This shift has facilitated interest in using these tools to monitor aspects of forest ecosystems including vegetation health, forest structure and composition, and potential habitat provided by these systems....

Life History of the Northern Rubber Boa (Charina bottae) in Oregon

Creator:: Leppin, Mark V.
Abstract:: The Northern Rubber Boa (Charina bottae) is a small, secretive boa native to the Pacific Northwest. Despite this being possibly the highest latitude boas and one of only two boas native to the continental U.S., it has received surprisingly little attention. Most of the research on the natural history of...

Products, services, and tax-motivated income shifting

Creator:: Deng, Zero and Rane, Scott G.
Abstract:: To better understand how the rise of global service-based activities affects multijurisdictional tax avoidance, we examine variation in tax-motivated income shifting among product- and service-based firms. We find that service-based firms are more responsive to income-shifting incentives, on average, than product-based firms and that the observed responsiveness among service-based firms...

Modeling the Visibility Distribution for Respondent-driven Sampling with Application to Population Size Estimation

Creator:: McLaughlin, Katherine R., Johnston, Lisa G., Jakupi, Xhevat, Gexha-Bunjaku, Dafina, Deva, Edona, and Handcock, Mark S.
Abstract:: Respondent-driven sampling (RDS) is used throughout the world to estimate prevalence and population size for hidden populations. Although RDS is an effective method for enrolling people from key populations in studies, it relies on a partially unknown sampling mechanism, and thus each individual’s inclusion probability is unknown. Current estimators for...
