Exploring The Phenomenon Of Distance In Children's Interactions With Touchscreen Digital Mathematics Games, Stephen I. Tucker, Patricia S. Moyer-Packenham

Teacher Education and Leadership Faculty Publications

This study examines the construct of distance – the degree of difficulty of interacting with something – as part of activity involving children using touchscreen digital games to learn mathematics. Ten fifth-grade children engaged in video-recorded semi-structured task-based interviews in which they used two touchscreen digital mathematics games on a touchscreen tablet and responded to semi-structured follow-up questions. Qualitative data analysis was iterative, featuring analytic memoing and eclectic coding techniques to identify themes related to distance. In advanced coding stages, magnitude coding was used to characterize the degree of distance present. Findings provide evidence of the presence of distance, changes …

Chromosomal Evolution And Apomixis In The Cruciferous Tribe Boechereae, Terezie Mandáková, Petra Hloušková, Michael D. Windham, Thomas Mitchell-Olds, Kaylynn Ashby, Bo Price, John Carman, Martin A. Lysak

Plants, Soils, and Climate Faculty Publications

The mustard family (Brassicaceae) comprises several dozen monophyletic clades usually ranked as tribes. The tribe Boechereae plays a prominent role in plant research due to the incidence of apomixis and its close relationship to Arabidopsis. This tribe, largely confined to western North America, harbors nine genera and c. 130 species, with >90% of species belonging to the genus Boechera. Hundreds of apomictic diploid and triploid Boechera hybrids have spurred interest in this genus, but the remaining Boechereae genomes remain virtually unstudied. Here we report on comparative genome structure of six genera (Borodinia, Cusickiella, Phoenicaulis, …

Machine Learning-Based Signal Degradation Models For Attenuated Underwater Optical Communication Oam Beams, Patrick L. Neary, Abbie T. Watnik, K. Peter Judd, James R. Lindle, Nicholas S. Flann

Computer Science Faculty and Staff Publications

Signal attenuation in underwater communications is a problem that degrades classification performance. Several novel CNN-based (SMART) models are developed to capture the physics of the attenuation process. One model is built and trained using automatic differentiation and another uses the radon cumulative distribution transform. These models are inserted in the classifier training pipeline. It is shown that including these attenuation models in classifier training significantly improves classification performance when the trained model is tested with environmentally attenuated images. The improved classification accuracy will be important in future OAM underwater optical communication applications.

Profiles In Practice: Stories Of Paleontology Within An Online, Scientific Community, Lisa Lundgren, Kent J. Crippen, Richard T. Bex Ii

Instructional Technology and Learning Sciences Faculty Publications

The Community of Practice framework has been used theoretically and empirically to describe the diverse ways people learn from one another through social interaction in a variety of specific contexts. To date, most research of this genre has favored investigating the community and domain constructs of the theory over the authentic practice construct. Those interested in recognizing and supporting science learning in non-school contexts across a lifespan are then limited in efforts to delineate how communities engage in domain-specific practice. This is especially relevant in the study of online environments which afford more democratic forms of participation. With the goal …

Beliefs And Self-Efficacy Of Parents Of Young Children With Hearing Loss, Sophie E. Ambrose, Margo Appenzeller, Alexandra Mai, Jean L. Desjardin

Journal of Early Hearing Detection and Intervention

The purpose of this study was to learn more about the beliefs and self-efficacy of parents of young children with hearing loss. Seventy-two parents completed the Scale of Parental Involvement and Self-Efficacy - Revised (SPISE-R), which queries parents about their child’s hearing device use and their perceptions of their own beliefs, knowledge, confidence, and actions pertaining to supporting their child’s auditory access and spoken language development. Two beliefs were identified that related to parents’ action scores and one belief was identified that related to children’s hearing device use. Knowledge and confidence scores were significantly correlated with action scores and children’s …

Using Technology To Monitor Hearing Device Use And Linguistic Environments: Early Intervention Providers’ Perspectives, Margo C. Appenzeller, Sophie E. Ambrose

Journal of Early Hearing Detection and Intervention

To optimize outcomes of children with hearing loss, early intervention professionals must work with families to optimize both children’s hearing device use and the linguistic and auditory features of their environments. Two technologies with potential use in monitoring these domains are data logging and Language Environment Analysis (LENA) technology. This study had two objectives: 1) to determine whether providers’ experiences, perspectives, and current practices indicate there is a need for tools to better monitor these domains, and 2) to gain a better understanding of providers’ experiences with and perspectives on use of data logging and LENA technology using an internet-based …

Rural Transportation Conference Participants’ Opinions And Concerns Pertaining To Transit For Older Adults, James W. Mjelde, Rebekka M. Dudensing, Geoffrey Battista, Jonathan Brooks, Maria Carrillo, Blane Counsil, Anil Giri, Man-Keun Kim, V. Dimitra Pyrialakou

Mobility remains a vital part of the well-being of rural-living, older adults and transportation disadvantaged persons. This study seeks to identify research and policy needs related to rural transit for older people and the transportation disadvantaged. To obtain this goal, the multidisciplinary study team conducted two activities as part of a 2016 rural transportation conference: a survey of conference attendees and open discussion to elicit additional information. Results suggest the attendees felt the need for rural transit for older adults would continue to increase with public and private funding being critical issues. Respondents had similar opinions about challenges and opportunities …

Estimation Of Autoregressive Parameters From Noisy Observations Using Iterated Covariance Updates, Todd K. Moon, Jacob H. Gunther

Electrical and Computer Engineering Faculty Publications

Estimating the parameters of the autoregressive (AR) random process is a problem that has been well-studied. In many applications, only noisy measurements of AR process are available. The effect of the additive noise is that the system can be modeled as an AR model with colored noise, even when the measurement noise is white, where the correlation matrix depends on the AR parameters. Because of the correlation, it is expedient to compute using multiple stacked observations. Performing a weighted least-squares estimation of the AR parameters using an inverse covariance weighting can provide significantly better parameter estimates, with improvement increasing with …

N3-Ligated Nickel(Ii) Diketonate Complexes: Synthesis, Characterization And Evaluation Of O2 Reactivity, Josiah G. D. Elsberg, Austin Peterson, Amy L. Fuller, Lisa M. Berreau

Chemistry and Biochemistry Faculty Publications

Interest in O₂-dependent aliphatic carbon–carbon (C–C) bond cleavage reactions of first row divalent metal diketonate complexes stems from the desire to further understand the reaction pathways of enzymes such as DKE1 and to extract information to develop applications in organic synthesis. A recent report of O₂-dependent aliphatic C–C bond cleavage at ambient temperature in Ni(II) diketonate complexes supported by a tridentate nitrogen donor ligand [(MBBP)Ni(PhC(O)CHC(O)Ph)]Cl (7-Cl; MBBP = 2,6-bis(1-methylbenzimidazol-2-yl)pyridine) in the presence of NEt₃ spurred our interest in further examining the chemistry of such complexes.

Snow Processes In Mountain Forests: Interception Modeling For Coarse-Scale Applications, Nora Helbig, David Moeser, Michaela Teich, Laure Vincent, Yves Lejeune, Jean-Emmanuel Sicart, Jean-Matthieu Monnet

Wildland Resources Student Research

Snow interception by the forest canopy controls the spatial heterogeneity of subcanopy snow accumulation leading to significant differences between forested and nonforested areas at a variety of scales. Snow intercepted by the forest canopy can also drastically change the surface albedo. As such, accurately modeling snow interception is of importance for various model applications such as hydrological, weather, and climate predictions. Due to difficulties in the direct measurements of snow interception, previous empirical snow interception models were developed at just the point scale. The lack of spatially extensive data sets has hindered the validation of snow interception models in different …

Outstanding Questions In Flower Metabolism, Monica Borghi, Alisdair R. Fernie

Biology Faculty Publications

The great diversity of flowers, their color, odor, taste, and shape, is mostly a result of the metabolic processes that occur in this reproductive organ when the flower and its tissues develop, grow, and finally die. Some of these metabolites serve to advertise flowers to animal pollinators, other confer protection towards abiotic stresses, and a large proportion of the molecules of the central metabolic pathways have bioenergetic and signaling functions that support growth and the transition to fruits and seeds. Although recent studies have advanced our general understanding of flower metabolism, several questions still await an answer. Here, we have …

Relationally Responsive Standpoint, Tyson Yunkaporta, Doris Shillingsworth

Journal of Indigenous Research

This paper is a commentary responding to the problem of Indigenous post-graduate students and scholars struggling with an understanding of Indigenous Standpoint Theory and either disengaging with it or including it in shallow or tokenistic ways that fail to advance knowledge in this emergent field (Foley, 2018). A framework grounded in respectful protocol is suggested as a way of coming into this knowledge safely and with cultural rigour. This framework was designed on the continent currently known as Australia by a Murruwarri Elder and a young Bama researcher over four years of journeys along song lines stretching from Qld and …

Prehistoric Irrigation In Central Utah: Chronology, Agricultural Economics, And Implications, Steven R. Simms, Tammy M. Rittenour, Chimalis Kuehn, Molly Boeka Cannon

Sociology, Social Work and Anthropology Faculty Publications

In 1928, Noel Morss was shown “irrigation ditches” along Pleasant Creek on the Dixie National Forest near Capitol Reef National Park, Utah, by a local guide who contended they were ancient. We relocated the site and mapped the route of an unusual mountain irrigation canal. We conducted excavations and employed OSL and AMS 14C showing historic irrigation, and an earlier event between AD 1460 and 1636. Geomorphic evidence indicates that the canal existed prior to this time, but we cannot date its original construction. The canal is 7.2 km long, originating at 2,450 m asl and terminating at 2,170 m …

Estimation Of Evapotranspiration And Energy Fluxes Using A Deep-Learning-Based High-Resolution Emissivity Model And The Two-Source Energy Balance Model With Suas Information, Alfonso F. Torres-Rua, Andres Ticlavilca, Mahyar Aboutalebi, Héctor Nieto, Maria Mar Alsina, Alex White, John H. Prueger, Joseph Alfieri, Lawrence Hipps, Lynn Mckee, William Kustas, Calvin Coopmans, Nick Dokoozlian

Civil and Environmental Engineering Faculty Publications

Surface temperature is necessary for the estimation of energy fluxes and evapotranspiration from satellites and airborne data sources. For example, the Two-Source Energy Balance (TSEB) model uses thermal information to quantify canopy and soil temperatures as well as their respective energy balance components. While surface (also called kinematic) temperature is desirable for energy balance analysis, obtaining this temperature is not straightforward due to a lack of spatially estimated narrowband (sensor-specific) and broadband emissivities of vegetation and soil, further complicated by spectral characteristics of the UAV thermal camera. This study presents an effort to spatially model narrowband and broadband emissivities for …

The Two Types Of Society: Computationally Revealing Recurrent Social Formations And Their Evolutionary Trajectories, Lux Miranda, Jacob Freeman

Sociology, Social Work and Anthropology Faculty Publications

Comparative social science has a long history of attempts to classify societies and cultures in terms of shared characteristics. However, only recently has it become feasible to conduct quantitative analysis of large historical datasets to mathematically approach the study of social complexity and classify shared societal characteristics. Such methods have the potential to identify recurrent social formations in human societies and contribute to social evolutionary theory. However, in order to achieve this potential, repeated studies are needed to assess the robustness of results to changing methods and data sets. Using an improved derivative of the Seshat: Global History Databank, …

Random Encounter And Staying Time Model Testing With Human Volunteers, Laura Garland, Eric Neilson, Tal Avgar, Erin Bayne, Stan Boutin

Ecology Center Publications

Ecology and management programs designed to track population trends over time increasingly are using passive monitoring methods to estimate terrestrial mammal densities. Researchers use motion‐sensing cameras in mammal studies because they are cost‐effective and advances in statistical methods incorporate motion‐sensing camera data to estimate mammal densities. Density estimation involving unmarked individuals, however, remains challenging and empirical tests of statistical models are relatively rare. We tested the random encounter and staying time model (REST), a new means of estimating the density of an unmarked population, using human volunteers and simulated camera surveys. The REST method produced unbiased estimates of density, regardless …

Sink Hollow Volume 9

Sink Hollow

Our world experiences radical change every day. With this change, things that used to make us feel grounded in our lives may not translate. Our realities may not hold true anymore. Through artistic expression, whatever form that takes, we re-examine what it means to be human after change.

Issue 9 takes a journey of re-examination during times of radical- and sometimes harsh- change. The collage of pieces we have curated re-examine so much of what I thought I knew and give an entirely new meaning to my reality. I would challenge you as you read this issue to re-examine change …

Quantitative Assessment Of Contested Water Uses And Management In The Conflict-Torn Yarmouk River Basin, Nicolas Avisse, Amaury Tilmant, David E. Rosenberg, Samer Talozi

Civil and Environmental Engineering Faculty Publications

The Yarmouk River basin is shared between Syria, Jordan, and Israel. Since the 1960s, Yarmouk River flows have declined more than 85% despite the signature of bilateral agreements. Syria and Jordan blame each other for the decline and have both developed their own explanatory narratives: Jordan considers that Syria violated their 1987 agreement by building more dams than what was agreed on, while Syria blames climate change. In fact, because the two countries do not share information, neither on hydrological flows nor on water management, it is increasingly difficult to distinguish between natural and anthropogenic factors affecting the flow regime. …

Material Outgassing Kinetics: The Development Of A Testing Capability, Alex Kirkman

Physics Capstone Projects

Contamination due to outgassing of materials can cause the degradation of critical hardware of a spacecraft. Using outgassing rates, kinetic expressions can be developed and used in models to predict the evolution of molecules and migration of contaminants for specific materials. These models could be used in the selection process of materials to help mitigate the amount of contamination of mission critical hardware for the expected life of the spacecraft. By using the ASTM E1559 test standard this can be achieved. This standard uses the quartz crystal microbalance (QCM) collection approach. A temperature-controlled effusion cell, containing the sample material, impinges …

Limits Of Growth: An Ecological Approach To Mainstream Economics, Jacob Cannon Alder

Undergraduate Honors Capstone Projects

Modern economists today rely on several fundamental assumptions in the same way physicists rely on laws governing energy and motion. Economists use growth—ideally unrestricted growth—as the key assumption upon which they build models and policy recommendations. The central economic theory explains that growth will enhance individual well-being over time. However, every known physical system has boundaries beyond which it will collapse, and the observed reality is that economic growth cannot be separated from physical resource consumption. As a result, many societies are overshooting physical, ecological boundaries. This project focuses on a few of the complexities generated by a growth-oriented economy …

Designing Technology For Different Scales Of Irrigation Scheduling, Paolo Alexander Consalvo

Undergraduate Honors Capstone Projects

Uncertainty in water availability is a significant challenge to the agriculture industry. Farmers and irrigators depend on novel uses of sensors and data to maximize water efficiency. Documented studies have demonstrated scheduling irrigation is a straightforward, deterministic means of achieving water efficiency. Irrigation scheduling uses several parameters to determine the moment of crop water stress due to available water in the soil. However, sensors and data for soil moisture and matric potential, a parameter describing water available to plants, have the potential to train machine learning algorithms to forecast water irrigation needs based on previous measurements. Satellite remote-sensing is another …
