The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

A detailed comparison of two separate radiometric calibration standards was conducted with analysis of error sources for each. One is a detector based standard, with radiance traceable to fundamental units using the electrical substitution method. The other is based on a calibrated field emission lamp (FEL) generating blackbody radiation. This study was motivated by the discontinuance of the FEL lamps by the manufacturer and a desire to calibrate sensors using non-blackbody spectral profiles. Three spectrometers were calibrated simultaneously by both methods to separate spectrometer artifacts from differences in the radiometric standards and error in the irradiance to radiance conversion procedure …

Hiding Operational Problems That Need To Be Revealed- A Study Linking Environmental Accidents And Product Recalls, Rick Hardcopf, Rachna Shah

Management Faculty Publications

Purpose:

This study investigates whether a firm that has experienced an environmental accident (EA) is less likely to conduct a product recall. If true, it would indicate that EAs tempt firms to hide operational problems that need to be revealed. The logic is that both events are operational failures that damage a firm’s reputation and share price. Following an EA, a firm may avoid a product recall to avoid providing additional evidence of operational incapability and social irresponsibility and thereby triggering amplified reputational and market penalties.

Stand Diversity Increases Pine Resistance And Resilience To Compound Disturbance, Sara J. Germain, James A. Lutz

Wildland Resources Faculty Publications

Background

Drought, fire, and insects are increasing mortality of pine species throughout the northern temperate zone as climate change progresses. Tree survival may be enhanced by forest diversity, with growth rates often higher in mixed stands, but whether tree defenses are likewise aided remains in question. We tested how forest diversity-productivity patterns relate to growth and defense over three centuries of climate change, competition, wildfire, and bark beetle attack. We used detailed census data from a fully mapped 25.6-ha forest dynamics plot in California, USA to conduct a spatially explicit, dendroecological assessment of large-diameter Pinus lambertiana survival following fire reintroduction. …

Lower Limb Muscle Activation In Young Adults Walking In Water And On Land, Christopher Long, Christopher J. Dakin, Sara A. Harper, Joonsun Park, Aaron Folau, Mark Crandall, Nathan Christensen, Talin Louder

Kinesiology and Health Science Faculty Publications

Previous research has shown that exercise interventions requiring increased activation of the tibialis anterior (TA), the primary ankle dorsiflexor, can improve walking performance in individuals with foot drop. Correspondingly, heightened drag forces experienced during walking performed in water may augment TA activation during the swing phase of gait, potentially leading to improved walking gait on land. Therefore, this study aimed to compare surface electromyographic (sEMG) activation in the TA and medial gastrocnemius (GM) during gait performed in water versus on land. Thirty-eight healthy, recreationally active young adults, comprising 18 females and 20 males, participated in the study. Each participant completed …

Using Dna Barcoding To Identify High-Priority Taxa (Hymenoptera: Ichneumonidae) From Great Smoky Mountains National Park, Emerie Landers, Brandon Claridge, Will Kuhn, Victoria Seymour, Hettie Peek, Scout Fluet, Jake Ramgren, Jake Phelps, Brayden Paulk, Lydia Cordner, Jeremy Blaschke

Biology Student Research

The All Taxa Biodiversity Inventory (ATBI) in Great Smoky Mountains National Park (GSMNP) seeks to document every species of living thing in the park. The ATBI is decades in progress, yet some taxa remain virtually untouched by taxonomists. Such "high priority" taxa include the hyper-diverse parasitoid wasp family Ichneumonidae. Despite the positive and multifaceted effects ichneumonids have on their environment, only a small percentage of those collected in the park have been identified as species, mostly to their complex morphology and overwhelming diversity. Recently, DNA barcoding has transformed biodiversity inventories, streamlining the process to be more rapid and efficient. To …

A Comprehensive Examination Of Age-Related Lower Limb Muscle Function Asymmetries Across A Variety Of Muscle Action Types, Kylee L. Heap-Eldridge, Brennan J. Thompson, Cody Fisher, Talin J. Louder, Jon Carey

Kinesiology and Health Science Faculty Publications

Previous research has found that lower limb muscle asymmetries increase with age and are linked to fall and injury risks. However, past studies lack a wide variety of muscle function modes and measures as well as comparison to a comparable younger age group. The purpose of this study was to examine age-related lower limb muscle function asymmetries across a variety of muscle action types and velocities in young and old adults. Lower limb balance, strength, power, and velocity were evaluated with concentric, isometric, isotonic, and eccentric muscle actions during a single-leg stance test and on single- and multi-joint dynamometers in …

Soil test correlation determines whether a soil test can be used to predict the need for fertilization based on the critical soil test value (CSTV). Our objectives were to compare the CSTV estimated from five combinations of correlation models and yield sufficiency interpretations and to select one method for soil test correlation performed with the Fertilizer Recommendation Support Tool (FRST). Four models were fit to three datasets with strong (Mehlich-1 K), moderate (Mehlich-3 K), or weak (Olsen P) correlations between soil test P or K and crop relative yield. We tested the arcsine-log calibration curve (ALCC), exponential (EXP), linear plateau …

Wildfire activity is increasing globally. The resulting smoke plumes can travel hundreds to thousands of kilometers, reflecting or scattering sunlight and depositing particles within ecosystems. Several key physical, chemical, and biological processes in lakes are controlled by factors affected by smoke. The spatial and temporal scales of lake exposure to smoke are extensive and under-recognized. We introduce the concept of the lake smoke-day, or the number of days any given lake is exposed to smoke in any given fire season, and quantify the total lake smoke-day exposure in North America from 2019 to 2021. Because smoke can be transported at …

Understanding Non-Designers' Practices And Processes In A Human-Centered Design Course, Luettamae Lawrence, Saadeddine Shehab, Mike Tissenbaum

Instructional Technology and Learning Sciences Faculty Publications

Human-centered design (HCD) has been identified in the literature as a useful problem-solving approach for learners. However, learning and applying HCD poses several challenges for students who are unfamiliar with this form of learning. In this paper, we analyse how a novice design team worked on a HCD class project to examine how non-designers learn about and integrate HCD practices into their project. We introduce the HCD taxonomy to define the processes and practices that students engage in. The team’s design work is triangulated across multiple data sources and revealed three challenges for engaging non-designers in HCD: 1) the need …

Temporal Separation Of Red And Blue Photons Does Not Increase Photon Capture Or Yield Of Lettuce, Jun Liu, Bruce Bugbee

Plants, Soils, and Climate Faculty Publications

Temporal separation of red (R) and blue (B) (alternating R/B) photons has been reported to increase leaf area, photon capture, and yield of lettuce compared with delivering both colors together (concurrent R+B). We grew three diverse lettuce cultivars (Grand Rapids, Rex, and Red Sails) under concurrent R+B photons (9/1 ratio) and alternating R/B photons (9/1 ratio) under an equal daily light integral (DLI) of either 8.6 or 23 mol·m^-2·d^-1. Contrary to five previous studies, we found no increase in either leaf area or fresh mass and dry mass in any of the alternating R/B photon treatments …

Rock Glaciers In Utah, Scott Hotaling, Kendall Becker, Matthew Morriss

All Current Publications

Utah’s primary water supply––winter snowpack––is in decline due to climate warming coupled with more precipitation falling as rain instead of snow. As snowpack dwindles, other sources of cold stream water, such as rock glaciers, will become more important. Rock glaciers contain significant volumes of internal ice covered by debris. This internal ice provides cold meltwater to mountain streams, sustaining flows in summer and supporting biodiversity. Rock glaciers are common in Utah’s mountains and are projected to be more stable under climate change than Utah’s snowpack. Thus, rock glaciers are likely to persist in their current form even as snowpack volumes …

Sensitivity Of Ocean Circulation To Warming During The Early Eocene Greenhouse, Sandra Kirtland Turner, Andy Ridgwell, Allison L. Keller, Maximilian Vahlenkamp, Adam K. Aleksinski, Philip F. Sexton, Donald E. Penman, Pincelli M. Hull, Richard D. Norris

Geosciences Faculty Publications

Multiple abrupt warming events ("hyperthermals") punctuated the Early Eocene and were associated with deep-sea temperature increases of 2 to 4 °C, seafloor carbonate dissolution, and negative carbon isotope (δ¹³C) excursions. Whether hyperthermals were associated with changes in the global ocean overturning circulation is important for understanding their driving mechanisms and feedbacks and for gaining insight into the circulation's sensitivity to climatic warming. Here, we present high-resolution benthic foraminiferal stable isotope records (δ¹³C and δ¹⁸O) throughout the Early Eocene Climate Optimum (~53.26 to 49.14 Ma) from the deep equatorial and North Atlantic. Combined with existing …
