Locking-It-In And Doubling: Mediating Second-Grade Students' Activity With Multiplicative Thinking, Jessica F. Shumway, Camille Lund, Joseph Kozlowski, Deborah Silvis, Jody Clarke-Midura, Ana Ashineh

Spatial Activities and Robot Coding (SPARC)

Using activity theory as a lens, we aimed to understand what second-grade students' interactions revealed about their thinking and what mediated students' engagement with important multiplicative ideas. In this setting, students interacted with multiplicative thinking using a coding robot and other artifacts as mediating tools. Through qualitative analysis, we found that students interacted with three concepts related to multiplicative thinking (i.e., composite units, doubling, iterating), and the lead mediators in their interactions included the robot's remote, dry erase marker and table, and peers/teacher. Students gravitated to artifacts that made sense to them, and the implication is that students need agency …

Streamlining Field Note Analysis: Leveraging Gpt For Further Insights, Saríah López-Fierro, Umar Shehzad, Alireza (Sina) Zandi, Jody Clarke-Midura, Mimi Recker

Publications

As an integral part of qualitative research inquiry, field notes provide important data from researchers embedded in research sites. However, field notes can vary significantly, influenced by the researchers' immersion in the field, prior knowledge, beliefs, interests, and perspectives. As consequence, their interpretation presents significant challenges. This study offers a preliminary investigation into the potential of using large language models to assist researchers with the analysis and interpretation of field notes data. Our methodology consisted of two phases. First, a researcher deductively coded field notes of six classroom implementations of a novel elementary-level mathematics curriculum. In the second phase, we …

Bird Richness As A Mediator Between Greenspace And Mental Health Relationships, Sihao Chena, Huaqing Wang, Wenyan Xu

Landscape Architecture and Environmental Planning Faculty Publications

Neighborhood greenspaces are widely known to benefit bird diversity and human mental health. However, whether bird richness mediates the relationship between greenspace and mental health is unknown. We ascertain such mediation effects in 294 census tracts in Los Angeles City. We obtained greenspace data from one-meter resolution satellite imagery, bird species data from eBird citizen science datasets, and prevalence of poor mental health from the US Centers for Disease Control and Prevention. Mediation analysis combined with spatial error models was used to assess the mediating effects while controlling for geographic, demographic, and socio-economic factors. We found that the higher greenspace …

Contrasting Effects Of Climate Warming On Hosts And Parasitoids: Insights From Rocky Mountain Aspen Leaf Miners And Their Parasitoids, Alisha A. Shah, Emily Hamant, Juan G. Rubalcaba, Beau Larkin, Andrew A. Forbes, H. Arthur Woods

Aspen Bibliography

Because temperature has pervasive effects on biological rates, climate warming may alter the outcomes of interactions between insect hosts and their parasitoids, which, for many host species, constitute the single largest source of mortality. Despite growing interest in parasitoid-host responses due to climate change, there are few empirical tests of thermal tolerance differences between non-model lepidopteran hosts and their parasitoids and almost none from mountain ecosystems where warming is occurring more rapidly. We examined the thermal ecology of a host–parasitoid interaction in the Rocky Mountains using the wild populations of the aspen leaf miner (Phyllocnistis populiella) and a …

Info-Cels: Informative Saliency Map-Guided Counterfactual Explanation For Time Series Classifications, Peiyu Li, Omar Bahri, Pouya Hosseinzadeh, Soukaïna Filali Boubrahimi, Shah Muhammad Hamdi

Computer Science Student Research

As the demand for interpretable machine learning approaches continues to grow, there is an increasing necessity for human involvement in providing informative explanations for model decisions. This is necessary for building trust and transparency in AI-based systems, leading to the emergence of the Explainable Artificial Intelligence (XAI) field. Recently, a novel counterfactual explanation model, CELS, has been introduced. CELS learns a saliency map for the interests of an instance and generates a counterfactual explanation guided by the learned saliency map. While CELS represents the first attempt to exploit learned saliency maps not only to provide intuitive explanations for the reason …

Wildland Resources Student Research

This study classified cows’ foraging behaviors using machine learning (ML) models evaluated through random test split (RTS) and cross-validation (CV) data partition methods. Models included Perceptron, Logistic Regression, Support Vector Machine, KNearest Neighbors, Random Forest (RF), and XGBoost (XGB). These models classified activity states (active vs. static), foraging behaviors (grazing (GR), resting (RE), walking (W), ruminating (RU)), posture states (standing up (SU) vs. lying down (LD)), and posture combinations with rumination and resting behaviors (RU_SU, RU_LD, RE_SU, and RE_LD). XGB achieved the highest accuracy for state classification (74.5% RTS, 74.2% CV) and foraging behavior (69.4% CV). RF outperformed XGB in …

Bryce Canyon Aspen: Recent Trends, Future Actions, Paul C. Rogers

Aspen Bibliography

In cooperation with Bryce Canyon National Park, we undertook a survey of quaking aspen (Populus tremuloides Michx.) conditions throughout the Park with the intention of better understanding conditions and prescribing corrective measures where needed. There are clear disparities within the Park between sustainable aspen conditions and failing stands. Based on condition of mature trees, but most importantly regeneration and recruitment of juvenile stems, most aspen forests within Bryce Canyon are in poor condition. Aspen recruitment—generally sapling-sized trees that have survived browsing ungulates—is the most important metric of future stand resilience and here we found 83% of all aspen sample …

Herbivory In A Low Arctic Wetland Alters Intraspecific Plant Root Traits With Consequences For Carbon And Nitrogen Cycling, Emily A. Chavez, Jaron Adkins, Bonnie G. Waring, Karen H. Beard, Ryan T. Choi, Lindsay Miller, Taylor Saunders, Trisha B. Atwood

Wildland Resources Faculty Publications

1. High latitude wetlands are ecologically important ecosystems due to their large carbon (C) storage capacity and because they serve as breeding and nesting habitat for large populations of migratory birds. Goose herbivory in wetland meadows affects leaf chemical and morphological traits and also influences soil properties by increasing soil temperature and depositing faeces. Grazing-induced changes to above-ground traits and soil properties impact C cycling, but the influence of grazing on root-mediated C and nitrogen (N) cycling has not been explored.

2. We investigated how goose herbivory in a low-Arctic coastal wetland in western Alaska affected root morphological, physiological and chemical traits …

Lifting-Line Predictions For The Ideal Twist Effectiveness Of Spanwise Continuous And Discrete Control Surfaces, Zachary S. Montgomery, Douglas F. Hunsaker, James J. Joo

Mechanical and Aerospace Engineering Faculty Publications

Modern materials and manufacturing technologies have allowed the construction of morphing wings that are able to continuously vary certain airfoil parameters such as twist, camber, or control surface deflection as a function of span. This work presents a twist effectiveness parameter as a means of comparing the ideal aerodynamic efficiency of spanwise continuous control surfaces (morphing wings) and spanwise discrete control surfaces (standard wings). A numerical algorithm is used to compute the twist effectiveness of both continuous and discrete control-surface designs over a wide range of planform shapes with evenly spaced actuation for inviscid, incompressible flow. Results included here show …

Evidence Of Substorm-Driven Penetration Electric Field Contributions To Low-Latitude Phenomena: Enhanced Upward Drifts, Plasma Bubble Development And Severe Scintillation, J. Sousasantos, F. S. Rodrigues, B. G. Fejer, R. W. Eastes, A. O. Moraes

All Physics Faculty Publications

In this work, it is demonstrated that substorm-driven penetration electric fields can efficiently enhance the upward plasma transport, favoring the development and structuring of plasma irregularities and the occurrence of scintillation on L-band signals. While most previous studies focus on investigating penetration electric fields during intense geomagnetic storms, here, the period used (April 01–05, 2020) was under very mild geomagnetic activity (−27 nT ≤ SYM-H ≤ 6 nT), so that interplanetary and disturbance dynamo contributions are minimized. This period comprised the same seasonal and solar flux conditions, while undergoing multiple short-lived substorms, making it well-suited to evaluate unequivocally: (a) to …

Spatio-Temporal Graph Neural Networks For Streamflow Prediction In The Upper Colorado Basin, Akhila Akkala, Soukaina Filali Boubrahimi, Shah Muhammad Hamdi, Pouya Hosseinzadeh, Ayman Nassar

Computer Science Student Research

Streamflow prediction is vital for effective water resource management, enabling a better understanding of hydrological variability and its response to environmental factors. This study presents a spatio-temporal graph neural network (STGNN) model for streamflow prediction in the Upper Colorado River Basin (UCRB), integrating graph convolutional networks (GCNs) to model spatial connectivity and long short-term memory (LSTM) networks to capture temporal dynamics. Using 30 years of monthly streamflow data from 20 monitoring stations, the STGNN predicted streamflow over a 36-month horizon and was evaluated against traditional models, including random forest regression (RFR), LSTM, gated recurrent units (GRU), and seasonal auto-regressive integrated …

A Checklist Of The Bees Of Utah, Joseph S. Wilson, Anthony Hunsaker, Terry L. Griswold, Olivia Messinger Carril

Biology Faculty Publications

Understanding bee distributions is essential to protecting these vital pollinators. Since conservation efforts and policies are often made at the state level, maintaining state-specific bee species lists can aid conservationists and policy makers. While several North American state- and province-level bee species lists have been published, few exist for the arid western states, where bee diversity tends to be higher. Here we provide a bee species list for Utah, compiled from online occurrence records from the Symbiota Collection of Arthropods Network (SCAN) and specimen records housed in the USDA-ARS Pollinating Insect Research Unit (BBSL). In total we document 1167 bee …

Advancements In Near Real-Time Bolide Detection: Continuum Calibration, Altitude Estimation, And Velocity Approximation Using Noaa Goes Glm Data, Eric Mckinney, Ryan Frazier, John Pratt, Mike Larsen, Philip Nelson, Hans Gunther

Space Dynamics Laboratory Publications

• Bolides, also known as fireballs, are a class of meteoroids that explosively break up and release large amounts of energy as they enter the Earth’s atmosphere

• While inherently of scientific value, bolides that occur over populous areas can result in alarm and, on rare occasions, terrestrial damage

• Thus, rapid bolide detection and characterization systems are advantageous for the scientific community, public interest, and political de-escalation efforts

• Jenniskens et al. (2018) and Rumpf et al. (2019) showed that the Geostationary Lightning Mapper (GLM) sensor onboard the NOAA Geostationary Operational Environmental Satellite (GOES) satellites can detect bolide signatures

Psychosocial And Audiological Characteristics In Misophonia: An Interdisciplinary Comparison Study Of Adults With Misophonia To Healthy Controls, Mercedes G. Woolley, Hailey E. Johnson, Emily M. Bowers, Doris Velasquez, Julie M. Petersen, Karen Muñoz, Michael P. Twohig

Psychology Student Research

Despite the increasing investigation into misophonia, its classification remains debated due to symptom overlap with audiological and psychological conditions, as well as methodological limitations in existing studies. In the present study, we compared a clinical sample of adults seeking treatment for misophonia with a non-treatment-seeking sample of age- and gender-matched healthy controls. In these two samples, we examined the psychological and audiological features of misophonia by assessing key psychological processes (anger, disgust, OCD symptoms, anxiety, depression, stress, wellbeing, and psychological inflexibility) and audiological features (hearing, hyperacusis, and tinnitus). We found that individuals with misophonia exhibit higher levels of psychological inflexibility …

Geosciences Faculty Publications

At the end of the Cretaceous, the massive Deccan trap (DT) volcanic eruptions are regarded as the primary driver of global climate deterioration. Accurate age models are key to unravel the sequence of events related to DT volcanism onset and effects on the global climate system. We establish a direct geochemical link between DT volcanism as recorded in marine osmium isotopic data and global climate change documented in benthic foraminifera carbon and oxygen isotope records. Based on our state-of-the-art astronomically calibrated age model, two major shifts in marine ¹⁸⁷Os/¹⁸⁸Os at 66.49 and 66.28 million years ago are …

Leveraging High-Frequency Sensor Data And U.S. National Water Model Output To Forecast Turbidity In A Drinking Water Supply Basin, John T. Kemper, Kristen L. Underwood, Scott D. Hamshaw, Dany Davis, Jason Siemion, James B. Shanley, Andrew W. Schroth

Watershed Sciences Faculty Publications

As high-frequency sensor networks increasingly enhance data-driven models of water quality, process-based models like the U.S. National Water Model (NWM) are generating accessible forecasts of streamflow at increasingly dense scales. There is now an opportunity to combine these products to construct actionable water quality forecasts. To that end, we couple streamflow forecasts from the NWM to a gradient-boosted decision tree algorithm (LightGBM) trained on 5+ years of high-frequency monitoring data to forecast in-stream turbidity levels in the Catskill Mountains, NY, USA. Results indicate LightGBM models are capable of relatively skillful predictions, which enable robust forecasts for 1–3 days lead times. …

Clickbait, masked behind interesting headlines and thumbnails, is often used to spread misinformation and trick users into clicking on social media posts or links that direct them to malicious websites. To help users protect against clickbait, we examined interventions based on persuasion theories including designs that used social consequence, personal consequence, and badges. To this end, we first conducted a preliminary study to translate the participants’ feedback into improving our initial designs, followed by a lab study with 20 participants (60% Male, 40% Female; 18-44 years old) aimed at understanding their perceptions of the improved interventions; we further updated our …

Specific Bacteria In Commercial Cheddar Cheese Can Cause Rubbery Texture And Poor Taste, Jordan Bond

Research on Capitol Hill

Unexpected pH changes often lead to a rubbery texture, off flavor and poor taste in commercially produced Cheddar, negatively affecting the quality of the cheese. Use of fast-acid producing (thermophilic) starter cultures in cheese manufacture is becoming common. 

Our goal was to discover the cause(s) for this pH variation. Knowing what causes pH changes will save Utah cheese manufacturers’ money, allowing them to pass the savings on to consumers and reduce waste. We posit that excessive use of fast acid producing thermophilic bacteria (S. thermophilus) can be the cause for pH variation.

The Mystery Of Baselevel Controls In The Incision History Of The Central Colorado Plateau, Natalie M. Tanski, Joel L. Pederson, Alan J. Hidy, Tammy M. Rittenour, James P. Mauch

Geosciences Student Research

Erosion can remain active and changing in landscapes long after tectonic drivers have ceased, potentially due to local‐geologic controls, climate changes, or geodynamics. We present new fluvial incision‐ rate histories and terrain analyses of the Colorado River system through the central Colorado Plateau to understand what has caused the variable erosion across this post‐orogenic landscape. Results from new cosmogenic and luminescence dating of fluvial terrace and upland gravel deposits in Glen and Meander Canyons establish incision‐rate histories that are marked by an Early‐Middle Pleistocene erosion hiatus, followed by ∼200 m of rapid incision over the last ∼350 kyr. Projection of …
