Mindfulness As Art Education, Self-Inquiry, And Artmaking, Mark Graham, Rebecca Lewis

Faculty Publications

This article presents an overview and continuation of a study investigating how artist awareness and critical response might provide a better understanding of mindfulness and its practice within art education. While there are distinct advantages to mindfulness practices in education, these practices might also have problematic aspects, such as helping people conform to oppressive structures in education rather than questioning them. The pandemic of 2020–2021 accentuated student concerns with social, emotional, and mental health and illuminated possible benefits of mindfulness practice. Results show that preservice art education students used mindfulness and data visualization to connect art and self-inquiry. Important findings …

Are We Essential, Or Sacrificial? The Effects Of Felt Public Gratitude On Essential Worker Recovery Activities During Covid-19, Hee Young Kim, Sijun Kim, Taeya M. Howell, Sarah P. Doyle, Nathan C. Pettit, Michael Bizzarro

Faculty Publications

COVID-19 has been characterized by unprecedented levels of public gratitude to some, but not all, essential workers. In this research, we integrate insights from the stigmatized occupations and gratitude literature to build theory on the positive and negative relationships between such displays of public gratitude and essential workers’ recovery activities. We argue that felt public gratitude positively relates to adaptive recovery activities (e.g., exercise) and negatively relates to maladaptive recovery activities (e.g., overdrinking). We further explain how felt public gratitude impacts (mal)adaptive recovery activities through (a) felt invisibility and (b) negative/positive affect. We find support for our predictions in a …

How Certain Robot Attributes Influence Human-To-Robot Social And Emotional Bonds, James Gaskin, P. Thomas Fife, Warren Rosengren

Faculty Publications

A growing population of humans are feeling lonely and isolated and may therefore benefit from social and emotional companionship. However, other humans cannot always be available to fulfill these needs, and such in-need individuals often cannot care for pets. Therefore, we explore how robot companions may be designed to facilitate bonds with humans. Our preliminary examination of 115 participants in a scenario based quasi-experimental study suggests that humans are more likely to develop social and emotional bonds with robots when those robots are good at communicating and conveying emotions. However, robots’ anthropomorphic attributes and responsiveness to external cues were found …

Interrelationships In Inventory Turnover Performance Between Supplier And Customer Firms, Joseph J. Henry, Peter Christensen, James C. Brau

Faculty Publications

Using inventory turnover to measure the efficiency of corporate inventory management, we perform econometric analyses to verify whether the inventory efficiency of a firm’s supply chain partners is a statistically significant driver of the firm’s own inventory efficiency. We test two mutually exclusive hypotheses. First, suppliers hold inventory on behalf of customers, effectively displacing inventory up the supply chain and resulting in a negative correlation between supplier and customer inventory turnover. Alternatively, inventory efficiency is integrated along the supply chain, resulting in a positive correlation between supplier and customer inventory turnover. Our bivariate and multivariate analyses of both firm- and …

Dannebrog On The Prairie: The Development Of Danishness In The Elk Horn–Kimballton Area Of Iowa, Lise Just

The Bridge

My father’s family comes from a small Danish farming community in Als parish in Jutland, where it was customary for young people to marry the sons and daughters of neighboring farmers. It was a closed community, largely because of a policy known as adscription (restricting peasants to the estate of their birth) that did not allow able-bodied men to leave the parish. This policy was in place for most of the eighteenth century, but in 1788, adscription was abolished. In the same period, the population in Denmark was increasing rapidly, due to, among other things, better hygiene and lower child …

Automatic Enrollment With A 12 Percent Default Contribution Rate, Josh Beshears, Ruofei Guo, David Laibson, Brigitte C. Madrian, James J. Choi

Faculty Publications

We study a retirement savings plan with a default contribution rate of 12 percent of income, which is much higher than previously studied defaults. Twenty-five percent of employees had not opted out of this default 12 months after hire; a literature review finds that the corresponding fraction in plans with lower defaults is approximately one-half. Because only contributions above 12 percent were matched by the employer, 12 percent was likely to be a suboptimal contribution rate for employees. Employees who remained at the 12 percent default contribution rate had average income that was approximately one-third lower than would be predicted …

Typing Fast Versus Typing Slow: Using Typing Dynamics To Reveal Authentic And Imposter Users, David Kim, Joseph S. Valacich, Jeffrey L. Jenkins, Manasvi Kumar

Faculty Publications

Real-time assessment of users' cognitive states has practical importance, allowing organizations to infer user behaviors. Realizing its importance, prior studies – specifically those using mouse cursor movements – have applied various theories to answer a similar question, i.e., how does a high cognitive load influence the users' device usage behavior? While numerous activities can increase cognitive load, we argue that the mechanisms behind how humans process information can more holistically be explained using Dual Process Theory (DPT) (i.e., when cognitive load is either low or high) and can be applied under a broad range of usage contexts. Using a within-participant …

"We Have Not Been Allowed The Liberty... To Worship As We Please" Nancy Naomi Tracy And The Denial Of Latter-Day Saint Religious Liberty, Derek Sainsbury

Faculty Publications

This article examines the life of Nancy Naomi Tracy as a lens into the Latter-day Saint struggle for religious liberty in nineteenth-century America. Joining the Church in 1834, Tracy endured repeated persecution—from the Missouri expulsions and the 1838 Mormon War to the federal antipolygamy campaigns of the 1880s—yet actively fought for her faith’s constitutional protections. As the only known female electioneer missionary in Joseph Smith’s 1844 presidential campaign, she embodied the Saints’ bold blend of religious conviction and political engagement. Drawing on Tracy’s three personal reminiscences (1880, 1885, and 1896–99), the study explores how her experiences as a wife, mother, …

Low-Fidelity Design Optimization And Parameter Sensitivity Analysis Of Tilt-Rotor Evtol Electric Propulsion Systems, Tyler Critchfield, Andrew Ning

Faculty Publications

Urban air mobility requires a multidisciplinary approach to tackle the important chal- lenges facing the design of these aircraft. This work uses low-to-mid fidelity tools to model rotor aerodynamics, blade structures, vehicle aerodynamics, and electric propulsion for a tilt-rotor electric vertical takeoff and landing (eVTOL) aircraft. We use gradient-based design optimization and extensive parameter sensitivity analysis to explore the design space and complex tradeoffs of tilt-rotor distributed electric propulsion systems.

Understanding The Role Of Online Teaching Assistants In Student Engagement, Sara H. Tuiloma, Charles R. Graham

Faculty Publications

In this paper, we examine how online teaching assistants (OLTAs) interact with students in terms of affective, behavioral, and cognitive support and the influence of OLTA training on these interactions. Through a thematic network analysis, using a tracking instrument and semi-structured interviews with 10 OLTAs, we examined how online university students are supported based on the quantity and quality of interactions with OLTAs, and how training contributes to interactions. Our research addressed two key questions: (1) How do OLTAs support learners in the quantity and quality of interactions? and (2) How does OLTA training around affective and behavioral support influence …

Barriers And Enablers To K-12 Blended Teaching, Courtney N. Hanny, Karen T. Arnesen, Qi Guo, Jordan Hansen, Charles R. Graham

Faculty Publications

The attributes of post-pandemic blended teaching (BT) will more closely resemble pre-Coronavirus conditions than the outbreak’s emergency remote teaching. Thus, barriers and enablers for teachers transitioning to BT after emergency remote teaching will be similar to those of early BT adopters. K-12 research has identified external and internal barriers and enablers to technology integration but has largely overlooked those of BT. This study involved analyzing 62 interviews of K-12 blended teachers to discover factors that enabled BT, stood as barriers to initial and continued blending efforts, and helped teachers overcome barriers. Teacher-perceived barriers included, among others, costs perceived as outweighing …

Teaching Non-Native Sound Contrasts Using Visual Biofeedback, Shawn L. Nissen

Faculty Publications

This demonstration will explain how non-native sound contrasts can be taught to second language (L2) learners using real-time visual biofeedback through an electropalatographic (EPG) sensor. How the EPG sensor is created from a dental mold and is subsequently produced will be shown during the presentation. An explanation of how a student can visualize the contact patterns of their speech and how a tutor might use the various features of the associated software to customize the instruction to an individual speaker will be illustrated during the presentation. Possible limitations, costs, and drawbacks to using the technology will also be discussed.

Effects Of Beaver Dams On Stream And Riparian Conditions On Public Lands In The United States’ Inland Northwest, Brett B. Roper

Western North American Naturalist

A before-after control-impact (BACI) design was used to simultaneously evaluate how stream habitat, macroinvertebrate communities, stream temperatures, and riparian conditions responded to beavers building dams within a stream reach. Summarized conditions describing beaver-dammed and undammed stream reaches suggested that 13 of the 18 evaluated metrics differed. After accounting for beavers’ selection of lower-gradient stream reaches with less forested cover, the number of stream and riparian metrics that differed significantly dropped to 5. Beaver dams increased pool area and depth, despite failing to increase the frequency of wood >10 cm in diameter. This suggests that beavers build dams utilizing pieces of …

Main And Interactive Effects Of Mental Health, Parent Ethnic Socialization, Discrimination On Bipoc Teens' Ethnic Identity, Emily Takamasa, Ashley M. Fraser, Adam Rogers

Undergraduate Honors Theses

Research would suggest that BIPOC (Black, Indigenous, People of Color) adolescents have the best developmental outcomes when strong, positive ethnic identity is acknowledged and embraced. This study investigated whether discrimination, internalizing symptomology, parent socialization, and/or interactions of these variables influenced adolescent ethnic identity, specifically in exploration, resolution, and affirmation to illuminate nuanced ways BIPOC youth can achieve positive ethnic identity. Recruited from third-party research panels, surveyed participants were adolescents (Mage = 15.28; 51.6% male) of diverse racial/ethnic groups and socioeconomic backgrounds from all regions of the U.S. Overall, the results showed that there were four significant main effects on ethnic …

Surface Modification Of 3d Printed Microfluidic Devices For Controlled Wetting In Two-Phase Flow, Chandler A. Warr, Nicole G. Crawford, Gregory P. Nordin, William G. Pitt

Faculty Publications

Microfluidic devices (MFDs) printed in 3-D geometry using digital light projection to polymerize monomers often have surfaces that are not as hydrophobic as MFDs made from polydimethylsiloxane. Droplet microfluidics in these types of devices are subject to droplet adhesion and aqueous spreading on less hydrophobic MFD surfaces. We have developed a post-processing technique using hydrophobic monomers that renders the surfaces of these devices much more hydrophobic. The technique is fast and easy, and involves flowing monomer without initiator into the channels and then exposing the entire device to UV light that generates radicals from the initiator molecules remaining in the …

Which Came First, The Money Or The Sex? Cross-Lagged, Indirect Associations Between Financial Management Behaviors And Sexual Satisfaction, Matthew Todd Saxey

Theses and Dissertations

Scholars have established cross-sectional connections between how married couples navigate their finances and their sexual relationship. For example, financial management behaviors have been shown to predict sexual satisfaction among newlywed couples. However, we know very little about the direction of the association between financial management behaviors and sexual satisfaction. Understanding which might predict the other, or if there might be a bidirectional association between the two, could provide direction on where to intervene to help newlywed couples with financial and/or sexual obstacles in their marriage. With three waves of dyadic data (N = 1,208 U.S. newlywed couples), I used structural …

Variation In The M-Opioid Receptor (Oprm1) And Offspring Sex Are Associated With Maternal Behavior In Rhesus Macaques (Macaca Mulatta), Zachary Baron

Theses and Dissertations

A m-opioid receptor (OPRM1) single-nucleotide-polymorphism, found in both humans and rhesus macaques mediates the mother-infant attachment bond. Because mothers treat their sons and daughters differently, it is somewhat surprising that the role of infant sex has not been assessed in the context of a maternal-OPRM1-genotype-by-infant-sex interaction. The present study investigates the effect of maternal-OPRM1-genotype and infant sex on mother-infant behaviors. Over the first six months of offspring life, mother-infant behavioral data assessing attachment quality was collected twice weekly from a large number of rhesus monkey mother-infant pairs (N=161 dyads; n=64 female infants, n=97 male infants). Mothers were genotyped for OPRM1 …

Quantifying Volatile Fatty Acid Concentrations During The Pretreatment And Anaerobic Digestion Process, Sascha Boutelle

Theses and Dissertations

Producing renewable energy from biomass or from the wastewater treatment process has gained momentum in the past 20 years. Anaerobic digestion has historically been used as one step in the waste treatment process, to both reduce the mass of waste that needs to be disposed of and to generate biogas. This process is typically only able to reduce 30-40% of the waste mass because of the recalcitrant nature of the waste streams being treated. Anaerobic pretreatment with the thermophilic bacteria Caldicellulosiruptor bescii (C. bescii) has been proven to increase the percentage of mass digested and consequently increase methane production to …

Understanding The Ahupua'a: Using Remote Sensing To Measure Upland Erosion And Evaluate Coral Reef Structure, Logan Kalaiwaipono Ellis

Theses and Dissertations

Under ever intensifying pressures from land use, climate change, and erosion, tropical islands are among the most vulnerable systems in the world. Terrestrial systems are weakened by intensifying land use patterns, the weakening of which is highlighted when high intensity rainfall events erode sediment and leads to sediment deposition on the marine system. The deposition of sediment on the marine system is a major stressor that can lead to weakened coral reefs and a decrease in marine resources commonly gathered for food. These interactions have led to the emergence of biocultural resource management strategies, one of which is the ahupua'a …

Of Bugs And Wildfires: Tracing The Impacts Of Changing Wildfire Regimes On Aquatic Bacteria And Macroinvertebrates Using Edna, Isabella M. Errigo

Theses and Dissertations

Human disruption of climate, habitat, and ignition has altered the behavior of wildland fire at local to continental scales. In many regions, novel fire regimes are emerging that threaten to exceed the capacity for local management to protect human wellbeing and ecosystem function. Simultaneous changes in climate, species composition, and fire management have resulted in extreme fire behavior in many regions. For the Western United States, the emerging novel fire regime consists of more frequent, severe, and intense wildfires, with annual area burned by wildfire having doubled and high-severity wildfire area having increased 8-fold since the 1980s. The impacts of …

Effect Of Climate History On The Genetic Structure Of An Antarctic Soil Nematode, Abigail C. Jackson

Theses and Dissertations

Historical climate disturbances such as glacial cycling and fluctuating stream, lake, and sea levels strongly influence the distribution and evolutionary trajectories of Antarctic terrestrial species. Antarctic invertebrates, with limited long-range mobility, including the ubiquitous sentinel nematode species Scottnema lindsayae, are especially sensitive to climate disturbances. We tested hypotheses associated with the historical geographic and population genetic structure of this species as it occurs across the McMurdo Dry Valleys (MDVs) of Antarctica. In order to reconstruct the influence of climate disturbance and ecological conditions on this species, partial mitochondrial COI gene sequences were sequenced and analyzed from individual S. lindsayae collected …

Computational Tools For Modeling And Simulation Of Sooting Turbulent Non-Premixed Flames, Victoria B. Stephens

Theses and Dissertations

Turbulent combustion systems are physically complex processes that involve many interdependent phenomena---including turbulent fluid dynamics, multi-component mass transfer, convective and radiative heat transfer, and multiphase flow---that occur over a wide range of length and time scales. Modeling and simulation studies complement experimental work by implementing and validating models and providing predictive capabilities, but current software tools are often limited by a lack of standardization and best practices, non-robust implementation, or over-specialization. Some topics in combustion CFD research, notably radiative heat transfer and soot modeling, are critically underrepresented in simulation studies as a result of software limitations. This project establishes and …

Core Microbiome To Fingerprint Dust Emission Sources Across The Western United States Of America, Detiare Lisa Leifi

Theses and Dissertations

Over the past century, dust emissions have increased in frequency and intensity due to anthropogenic influences and extended droughts. Dust transports microbes, nutrients, heavy metals and other materials that may then change the biogeochemistry of the receiving environments. The purpose of this study was to find whether unique bacterial communities may provide distinct fingerprints of dust sources in the Western USA. We collaborated with the National Wind Erosion Research Network (NWERN) to identify bacterial core communities (core) of dust from ten NWERN sites, and compared communities to location, soil, and regional characteristics. In order of importance, precipitation levels (F = …

The Effect Of Gut Microbiota On Overwintering Success In Mule Deer, Emma Wilcox

Theses and Dissertations

Mule deer are an important rangeland grazer, large prey species, and game animal for the state of Utah, so herd size is monitored and managed actively. A significant cause of population decline is poor overwintering survival, including from the lack of available forage during winter months. Mule deer energy storage is correlated with greater overwintering success, so physical estimates of energy storage including body condition score (BCS), rump fat (RF), and loin thickness (LT), can be used to track and predict a herd's health. Current methods of collecting deer information are costly, time consuming, and cause physical stress to deer, …

Wildfire Modeling With Data Assimilation, Andrew Johnston

Theses and Dissertations

Wildfire modeling is a complex, computationally costly endeavor, but with droughts worsening and fires burning across the western United States, obtaining accurate wildfire predictions is more important than ever. In this paper, we present a novel approach to wildfire modeling using data assimiliation. We model wildfire spread with a modification of the partial differential equation model described by Mandel et al. in their 2008 paper. Specifically, we replace some constant parameter values with geospatial functions of fuel type. We combine deep learning and remote sensing to obtain real-time data for the model and employ the Nelder-Mead method to recover optimal …
