Advancing Transparency And Impact Of Research: Initiating Crosstalk Between Indigenous Research And Mainstream “Open Science”, P. Priscilla Lui, Monica C. Skewes, Sarah Gobrial, David Rollock

Journal of Indigenous Research

To answer questions about human psychology, psychological science needs to yield credible findings. Because of their goals of understanding people’s lived experiences and advocating for the needs of the Native communities, Indigenous scholars tend to use community-based participatory research (CBPR) or approach science from a constructivist framework. The primary goal of mainstream psychological science is to uncover generalizable facts about human functioning. Approached from a postpositivist framework, mainstream psychological scholars tend to assume the possibility of identifying researcher biases and achieving objective science. Recently, many psychological findings failed to replicate in new samples. The replication crisis has raised concerns about …

Data From: [Sn8]6−-Bridged Mixed-Valence Zni/Znii In {[K2znsn8(Znmes)]2}4− Inverse Sandwich-Type Cluster Supported By A Zni−Zni Bond, Alexander I. Boldyrev, Nikolay Tkachenko

Browse all Datasets

Since [Sn8]6− was discovered from the solid-state phase in 2000, its solution chemistry has been elusive due to the high charges and chemical activity. Herein, we report the synthesis and characterization of an inverse sandwich-type cluster dimer {[K2ZnSn8(ZnMes)]2}4− (1 a), in which the highly charged [Sn8]6− is captured by mixed-valence ZnI/ZnII to form the dimer {closo-[Zn2Sn8]}2 moieties bridged by a Zn-Zn bond. Such Zn-Sn cluster not only exhibits a novel example of mixed-valence ZnI/ZnII for stabilizing highly active anion species, but also indicates the [Sn8]6− cluster can act as a novel bridging ligand, like arene, with a η4:η4-fashion. Theoretical calculations …

Data From: All-Metal Σ-Antiaromaticity In Dimeric Cluster Anion {[Cuge9mes]2}4−, Alexander I. Boldyrev, Nikolay Tkachenko

In this work, we report a dimeric cluster anion, {[CuGe9Mes]2}4−, which was isolated as the [K(2,2,2-crypt)]+ salt and characterized by using single-crystal X-ray diffraction and ESI mass spectroscopy. The title cluster represents the first locally σ-antiaromatic compound in the solid state, as well as the first heteroatomic antiaromatic compound.

Transport-Based Pattern Recognition Versus Deep Neural Networks In Underwater Oam Communications, Patrick L. Neary, Jonathan M. Nichols, Abbie T. Watnik, K. Peter Judd, Gustavo K. Rohde, James R. Lindle, Nicholas S. Flann

Space Dynamics Laboratory Publications

Comparisons between machine learning and optimal transport-based approaches in classifying images are made in underwater orbital angular momentum (OAM) communications. A model is derived that justifies optimal transport for use in attenuated water environments. OAM pattern demultiplexing is performed using optimal transport and deep neural networks and compared to each other. Additionally, some of the complications introduced by signal attenuation are highlighted. The Radon cumulative distribution transform (R-CDT) is applied to OAM patterns to transform them to a linear subspace. The original OAM images and the R-CDT transformed patterns are used in several classification algorithms, and results are compared. The …

Community Supported Agriculture: Accepting Snap Payments, Kelsey Hall, Roslynn Mccann

All Current Publications

Participating in a community supported agriculture (CSA) share is one way for individuals with low income to use their Supplemental Nutrition Assistance Program (SNAP) benefits in buying local, seasonal fruits and vegetables. The U.S. Department of Agriculture’s Food and Nutrition Service (USDA FNS) authorizes businesses to accept SNAP benefits, including direct marketing farmers and nonprofit food buying cooperatives operating a CSA. SNAP is the largest federal nutrition assistance program, formerly known as food stamps. Eligible individuals and families use an Electronic Benefit Transfer (EBT) card, similar to a debit card, to purchase eligible food at SNAP authorized vendors. In Utah, …

Trophic Niches Of Native And Nonnative Fishes Along A River-Reservoir Continuum, Casey A. Pennock, Zachary T. Ahrens, Mark C. Mckinstry, Phaedra Budy, Keith B. Gido

Watershed Sciences Faculty Publications

Instream barriers can constrain dispersal of nonnative fishes, creating opportunities to test their impact on native communities above and below these barriers. Deposition of sediments in a river inflow to Lake Powell, USA resulted in creation of a large waterfall prohibiting upstream movement of fishes from the reservoir allowing us to evaluate the trophic niche of fishes above and below this barrier. We expected niche overlap among native and nonnative species would increase in local assemblages downstream of the barrier where nonnative fish diversity and abundance were higher. Fishes upstream of the barrier had more distinct isotopic niches and species …

Chapter 2- Productive Disruptions: Resilient Pedagogies That Advocate For Equity, Beth Buyserie, Rachel Welton Bryson, Rachel Quistberg

Resilient Pedagogy

When the COVID-19 pandemic shuttered universities in March 2020, many students and faculty were thrown into shifting uncertainties regarding course delivery and pedagogy. As the pandemic persisted, faculty and students experienced new stressors caused by social isolation, unequal access to technology and resources, economic distress, and many other factors. In addition, the killings of George Floyd, Breonna Taylor, and others in the Black community sparked widespread social unrest that added to and compounded the emotional and material weight of the pandemic. Amid this tumult, higher-education faculty began asking questions about how to move forward with pedagogies resistant to unpredictable and …

Chapter 1- Resilient Pedagogy And Self-Determination: Unlocking Student Engagement In Uncertain Times, Lindsay C. Masland

Resilient Pedagogy

When the COVID-19 pandemic hit in spring of 2020, like many educators, I experienced a definite disruption in the structure and plans I had designed for my courses. I was teaching a mix of graduate and undergraduate classes—some with as few as seven students, others with as many as 98, some upper-level skills-based courses, others in the broad general education arena, but all of them designed exclusively for face-to-face delivery. In fact, due to some long-standing institutional prejudices against online instruction, the opportunity to teach in a mode other than face-to-face had never materialized over the 10 years I had …

Chapter 3- How Adult Education Can Inform Optimal Online Learning, David S. Noffs, Kristina Wilson

Resilient Pedagogy

David's Story

I first met Krissy Wilson in 2015 when I was asked to design a new graduate course at Northwestern University on learning environment design. Krissy was part of the talented Distance Learning team in the School of Professional Studies. I was a teacher, instructional specialist, and reluctant learning management system administrator at an arts-based city college where I had worked for almost 15 years.

Chapter 8- Creating Adaptable Courses: A Course Design Approach That Accommodates Flexible Delivery, Kosta Popovic, Eric M. Reyes, Jennifer B. O'Connor, Kay C. Dee, Ella Ingram

Resilient Pedagogy

In early 2020, educators and students around the world endured lapses in quality of educational experiences due to the disruption caused by COVID-19. In return for these lapses, students continued their programs of study within previously established timelines, and educators balanced helping students achieve learning objectives while keeping a manageable workload. Moving forward, students will expect educators and their institutions to deliver high-quality education when disruptions occur, like natural disasters, facilities emergencies, or supply chain disturbances. This expectation will extend to all modes of delivery. We assert that training educators to build adaptable courses that provide them and their students …

Chapter 11- Team-Based Learning Brings Academic Rigor, Collaboration, And Community To Online Learning, Elizabeth Winter, Michele C. Clark, Christopher Burns

Resilient Pedagogy

In early 2020, instructors were faced with a critical and immediate need to move education online in the face of the COVID-19 pandemic. The decision to discontinue face-to-face classes as a protection from the COVID-19 virus presented several questions and challenges, including the need to quickly develop online classes without adequate time to consider the effectiveness of different strategies. While online learning provides accessible and safe educational opportunities for students sheltering in place as a protection against the COVID-19 pandemic, faculty may question if online education provides the academic rigor, needed competencies, and student learning outcomes they hoped for in …

Chapter 9- A New Normal In Inclusive, Usable Online Learning Experiences, Christopher Phillips, Jared S. Colton

Resilient Pedagogy

The most obvious consequence of the COVID-19 pandemic in higher education has been more students accessing their classes remotely without having the technology and other resources readily available on their local campuses. Students from underrepresented groups have been disproportionately affected as a result of COVID-19, particularly students of color (Alvarez, 2020) and students with disabilities (Hill, 2020; National Center, 2020). This neglect of underrepresented groups in higher education is not unique to the pandemic, of course, and sadly is nothing new to higher education, but COVID-19 has made this problem more apparent.

Chapter 13- Asynchronous Discussions For First-Year Writers And Beyond: Thinking Outside The Ppr (Prompt, Post, Reply) Box, Miriam Moore

Resilient Pedagogy

Asynchronous discussions can challenge even experienced online learners and teachers: forums can become perfunctory hoops for students to jump through, particularly in the common PPR (prompt, post, reply) format, in which students answer a prompt and then reply to one or more other students. As a peer reviewer for online courses, I have seen rich and insightful discussions that engage students and promote learning, as well as forums that scarcely resemble discussions at all. Research on cultivating dialogue in online discussions has targeted primarily upper-division or graduate courses (see Andreson, 2009; Delahunty, 2018; Delahunty et al., 2014; Garrison et al., …

A Practical Guide To Selecting Models For Exploration, Inference, And Prediction In Ecology, Andrew T. Trednnick, Giles Hooker, Stephen P. Ellner, Peter B. Adler

Wildland Resources Faculty Publications

Selecting among competing statistical models is a core challenge in science. However, the many possible approaches and techniques for model selection, and the conflicting recommendations for their use, can be confusing. We contend that much confusion surrounding statistical model selection results from failing to first clearly specify the purpose of the analysis. We argue that there are three distinct goals for statistical modeling in ecology: data exploration, inference, and prediction. Once the modeling goal is clearly articulated, an appropriate model selection procedure is easier to identify. We review model selection approaches and highlight their strengths and weaknesses relative to each …

Examining The Influence Of Instructor Interventions On Group Collaboration, Luettamae Lawrence, Taylor Tucker, Emma Mercier

Instructional Technology and Learning Sciences Faculty Publications

Collaborative problem solving is often used in STEM higher education courses to support conceptual knowledge and teamwork. However, course teaching assistants (TAs) often lack the collaborative pedagogical knowledge necessary to orchestrate this form of learning. In this paper, we examine TAs’ orchestration strategies and technology used to understand how these factors influence groups’ collaboration. Contributions from this paper describe the interplay among technology, strategies, and groups’ collaboration toward understanding how to support collaboration in these courses.

Wildland Resources Faculty Publications

The northern spotted owl (Strix occidentalis caurina) inhabits older coniferous forests in the Pacific Northwest and has been at the center of forest management issues in this region. The immediate threats to this federally listed species include habitat loss and competition with barred owls (Strix varia), which invaded from eastern North America. We conducted a prospective meta-analysis to assess population trends and factors affecting those trends in northern spotted owls using 26 years of survey and capture-recapture data from 11 study areas across the owls' geographic range to analyze demographic traits, rates of population change, and …

‘Theses’ Going To Be Good!: A How To Guide On Dealing With Large Complex Cataloging Projects, Paul Daybell, Becky Skeen, Liz Woolcott, Melanie Shaw, Seth Westernburg

Library Faculty & Staff Presentations

Utah State University Libraries undertook a complete barcoding and cataloging of their Theses and Dissertations. Due to irregular cataloging policies, only 1/3 of the collection had been cataloged. Using a workflow-driven approach, the cataloging team of student technicians and catalogers used a combination of automations, batch processing, and a relational database to pull existing record information and build new, improved records. Presenters will discuss the process developed, the tools that were used, and the outcomes of the project.

Drought-Tolerant Options For Southwest Agriculture: Grasses, Grains, And Legumes, Emily Rice, Kynda R. Curtis

All Current Publications

The arid Southwest has been heavily impacted by drought and climate change. The Southwest states are some of the driest in the nation. Droughts damage pastures and crops, leading to economic losses in agriculture. This fact sheet is the first in a series of three that provide an overview of drought-tolerant crops, grasses, and native plants, which may assist in maintaining agricultural production for food and feed and sustain grasslands and rangelands in the arid Southwest. The following grasses, grains, and legumes used for forage, fodder, and human consumption, are all drought tolerant and, in many cases, tolerate salty soil …

Electron Yield Decay Curves For Analysis Of Sample Charging And Neutralization, Matthew Robertson

Utah Space Grant Consortium

Excess charge on a material will affect the electron yield of the material. Electron yield is an attribute of materials which describe how the material behaves when irradiated with electrons. It is the ratio of the number of electrons going into the material over the number of electrons leaving the material. Understanding how a sample charges is important in both how it affects the electron yield and how it can be neutralized.

Evolution Of A Digital Twin For Wing Assembly By Refill Friction Stir Spot Welding, Johnathon Hunt

Utah Space Grant Consortium

Refill Friction Stir Spot Welding (RFSSW) is an emerging solid state joining process for thin sheet aluminum. Many researchers are developing RFSSW process parameters and best practices for manufacturing, thus enabling the use of RFSSW in many industries. Within this development, this work focuses to predict the resultant residual stresses and distortion in a joined part after welding. These residual stresses are caused by the heat & mechanical inputs from the RFSSW process. This report provides the preliminary results of the two step solution to resultant temperature and stresses from a series of RFSSW in thin sheet aluminum.

Reliable Mode Tracking In Gradient-Based Optimization Frameworks With Flutter Constraints, Taylor Mcdonnell

Utah Space Grant Consortium

In this paper a new mode tracking method is presented which incorporates backtracking logic to maintain a high degree of confidence in mode tracking results. The effectiveness of this mode tracking method is demonstrated on linear and nonlinear aeroelastic systems of varying complexity in the context of aeroelastic analyses and optimizations with stability constraints. The high degree of confidence in mode correlations provided by the new mode tracking method allows for the creation and use of mode-specific C¹ continuous stability constraints in gradient-based optimization frameworks. Using our mode tracking method in the context of a gradient-based optimization framework with …

Sparse Monocular Scene Reconstruction Using Rolling Voxel Maps, Jacob Johnson

Utah Space Grant Consortium

We present a method for creating 3D obstacle maps in real-time using only a monocular camera and an inertial measurement unit (IMU). We track a large amount of sparse features in the image frame. Then, given scale-accurate pose estimates from a front-end visual-inertial odometry (VIO) algorithm, we estimate the inverse depth to each of the tracked features using a keyframe-based feature-only bundle adjustment. These features are then accumulated within a probabilistic robocentric 3D voxel map that rolls as the camera moves. This local rolling voxel map provides a simple scene representation within which obstacle avoidance planning can easily be done. …

Passive Atmospheric Safety Feature For Small Molten Salt Reactors In Accident Conditions, Brent Edgerton

Utah Space Grant Consortium

This investigation aims to discover the utility of atmospheric cooling of residual heat in Martian applications (1.5 MW_t). It also considers the possible terrestrial application (45 MW_t) of these concepts. The peculiarities of atmospheric cooling require novel geometric arrangements and material selection. The average convection coefficient is derived and applied to ANSYS Transient Thermal analysis for both terrestrial and Martian environments. This preliminary analysis found that atmospheric cooling is a viable method of Martian passive cooling and may serve as a possible method in terrestrial conditions. The key finding of this investigation is that the …

Tuning Radiation And Microgravity Exposure For Human Brain Organoids, Bailey Mcfarland

Utah Space Grant Consortium

The environment of space, specifically radiation and microgravity, poses a substantial threat to astronauts' brain health. Understanding the damage mechanism and therefore paving the way to finding potential remedies is critical to protect astronauts during space flight. Current models are insufficient at representing the human brain, and insufficient research has been conducted on the effect of radiation and microgravity on the higher structures of the human brain. This ongoing research aims to use brain organoids, a tissue-engineered model that recapitulates the human brain's anatomy and structure and investigate the effects of radiation and microgravity on the brain. At the current …
