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,...

Recent Stressful Experiences and Electronic Nicotine Product Use Among Young Adults

Creator:: Gherghe, Anda, Fahey, Kaline M.L., and Cservenka, Anita
Abstract:: The goal of the current study was to examine how specific recent stressors are related to electronic nicotine product use among young adults. Despite increases in electronic nicotine product use among adults, stressors shaping the use of these products remain largely unknown. The current study examined the types and average...

Injury and Performance-Related Running Biomechanics in Advanced Footwear Technology Compared to Minimalist Footwear

Creator:: Hannigan, J. J., Westley, Luisa, and Jin, Li
Abstract:: Road racing shoes have recently evolved to incorporate maximal midsole cushioning and an embedded carbon fiber plate. Shoes in this category have been labeled ‘Advanced Footwear Technology’ (AFT) and may significantly contribute to improvements in running economy, in part due to biomechanical changes at the foot and ankle. However, little...

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...

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...

Star CEOs: Influence on Competitor CEOs’ Risk-Taking

Creator:: Cho, Sam Yul and Choi, Yohan
Abstract:: This study explores how a star CEO winning a prestigious award and prior firm performance relative to competitive aspirations, defined as the performance of industry peers, influence competitor CEOs’ risk-taking. Using a difference-in-differences methodology, we find that when a star CEO wins a prominent award, competitor CEOs increase their risk-taking....

Early Childhood Teachers’ Relationships with Families When Children Experience Adversity

Creator:: Lewis, Hillary R., Lipscomb, Shannon T., Hatfield, Bridget E., Jäderholm, Christina M., and Tominey, Shauna L.
Abstract:: Quality relationships among families and teachers in early care and education (ECE) hold promise to nurture resilience among children impacted by adversity. However, little is known about how adverse childhood experiences (ACEs) may also affect the interactions between families and teachers. This study uses quantitative survey data from families (N...

Herbage and Sheep Production from Simple, Diverse, and Legume Pastures Established in an Agrivoltaic Production System

Creator:: Andrew, Alyssa C., Higgins, Chad W., Smallman, Mary A., Prado-Tarango, David E., Rosati, Adolfo, Ghajar, Shayan, Graham, Maggie, and Ates, Serkan
Abstract:: Agrivoltaic systems combine solar energy and agriculture, promoting dual land use. Although grazing sheep in these systems is common, research on intentionally designed pastures to increase production is lacking. This study seeks to compare the herbage growth and lamb production in simple, diverse, and legume pastures in an agrivoltaic system...

Blending of Virgin and RAP Binder for Asphalt Mixes with High RAP Contents: A Pilot Study

Creator:: Lewis, Sunny, Coleri, Erdem, Sukhija, Mayank, and Sreedhar, Shashwath
Abstract:: Reusing reclaimed asphalt pavement (RAP) presents an opportunity to reduce environmental burdens and encourage sustainable development. However, a concern exists about blending RAP binder and virgin asphalt binder. While RAP mixtures assume complete blending between these binders, the actual extent of this blending remains uncertain. Lower blending percentages can reduce...

Study More Tomorrow

Creator:: Pugatch, Todd, Schroeder, Elizabeth, and Wilson, Nicholas
Abstract:: We design a commitment device for college students, “Study More Tomorrow,” conduct a randomized controlled trial testing a model of its takeup, and measure its effect on tutoring attendance and grades. The device commits students to attend tutoring if their midterm grade falls below a pre-specified threshold. Unlike other commitment...
