Coal Ash Dumps In The Mountain West, Julia Salangsang, Nicole Diaz Del Valle, Zachary Billot, Caitlin J. Saladino, William E. Brown Jr. Jul 2023

Coal Ash Dumps In The Mountain West, Julia Salangsang, Nicole Diaz Del Valle, Zachary Billot, Caitlin J. Saladino, William E. Brown Jr.

Environment

This fact sheet presents data on coal ash dumps, their management, and the pollutants that exist at each site in the Mountain West states of Arizona, Colorado, Nevada, New Mexico, and Utah. The original report includes data on coal ash dumping sites for all 50 states.


Synecological Response Of Spring Benthic Prokaryotes And Macroinvertebrates To Paleozoic Roof Pendant-Derived Calcium, Ariel D. Friel, Khaled Pordel, Zachary Meyers, Cale O. Seymour, Nicole J. Thomas, Fred M. Philips, Jeffrey R. Knott, Donald W. Sada, Laura Rademacher, Marty Frisbee, Brian P. Hedlund May 2023

Despite the ecological significance of desert springs, little is known about relationships between spring hydrogeochemistry and ecology, particularly over multiple trophic levels. Here, we surveyed microbial communities (bacteria and archaea) and benthic macroinvertebrate (BMI) communities in springs that recharge through granitoid bedrock in Owens Valley, CA, to determine whether subtle geochemical differences imparted by metamorphosed roof pendant weathering in the source area affect spring ecosystems. Relative to other springs, roof-pendant-recharged springs were characterized by elevated (1) Ca2+/Na+, Ca2+/Mg2+, and divalent/monovalent cation ratios, (2) relative abundance of taxa inferred to be benthic aerobes and prosthecate/stalked bacteria, and (3) abundance and diversity …


Comparative Nutritional Assessment And Metabolomics Of A Wrky Rice Mutant With Enhanced Germination Rates, Santiago Bataller, Anne J. Villacastin, Qingxi J. Shen, Christine Bergman Apr 2023

Comparative Nutritional Assessment And Metabolomics Of A Wrky Rice Mutant With Enhanced Germination Rates, Santiago Bataller, Anne J. Villacastin, Qingxi J. Shen, Christine Bergman

Life Sciences Faculty Research

Rice is the primary staple food for half the world’s population. Climate change challenges and food insecurity supports the need for rice with agronomically advantageous traits. We report on a transposon insertional rice mutant with enhanced germination rates. This trait is advantageous for rice growth in limited water regions and to reduce yield constraints caused by weed and bird competition. Evaluations of vital nutritional components, compositional analysis, and comparative metabolomics on threshed grain samples are performed, as these assays are those used to assess the safety of foods from genetically modified crops. Compared with the wild type (cv. Nipponbare), oswrky71 …


Holistic Framework To Contextualize Dietary Quality Assessment: A Critical Review, Jessica M. Phelan, Richard R. Rosenkranz, Connor J. Phelan, Sara K. Rosenkranz Feb 2023

Holistic Framework To Contextualize Dietary Quality Assessment: A Critical Review, Jessica M. Phelan, Richard R. Rosenkranz, Connor J. Phelan, Sara K. Rosenkranz

Kinesiology and Nutrition Sciences Faculty Publications

Numerous dietary quality indices exist to help quantify overall dietary intake and behaviors associated with positive health outcomes. Most indices focus solely on biomedical factors and nutrient or food intake, and exclude the influence of important social and environmental factors associated with dietary intake. Using the Diet Quality Index- International as one sample index to illustrate our proposed holistic conceptual framework, this critical review seeks to elucidate potential adaptations to dietary quality assessment by considering—in parallel—biomedical, environmental, and social factors. Considering these factors would add context to dietary quality assessment, influencing post-assessment recommendations for use across various populations and circumstances. …


Household Food Security In The Mountain West, 2021, Zachary Walusek, Corryn Richardson, Issac Hernandez-Alcaraz, Annie Vong, Caitlin J. Saladino, William E. Brown Jr. Feb 2023

Household Food Security In The Mountain West, 2021, Zachary Walusek, Corryn Richardson, Issac Hernandez-Alcaraz, Annie Vong, Caitlin J. Saladino, William E. Brown Jr.

Health

This fact sheet examines data on household food security published by the United States Department of Agriculture. We examine the prevalence of household food insecurity and very low food security in Mountain West states (Arizona, Colorado, Nevada, New Mexico, and Utah) and the United States national average for comparative analysis.


Sport And Mental Health Performance Optimization In An Adolescent Gymnast: A Case Evaluation, Davy Phrathep, Brad C. Donohue, Brenna N. Renn, John Mercer Dr., Daniel N. Allen Feb 2023

Sport And Mental Health Performance Optimization In An Adolescent Gymnast: A Case Evaluation, Davy Phrathep, Brad C. Donohue, Brenna N. Renn, John Mercer Dr., Daniel N. Allen

Psychology Faculty Research

The Optimum Performance Program in Sports (TOPPS) is a multi-component, sport-specific Family Behavior Therapy that has demonstrated improved sport performance, relationships, and mental health outcomes in adult and adolescent athletes with, and without, diagnosed mental health disorders in clinical trials. The current case trial demonstrates successful implementation of a novel component of TOPPS (i.e., talk aloud optimal sport performance imagery leading to dream mapping) in a biracial Latina and White adolescent gymnast without a mental health diagnosis. The participant demonstrated significant improvements from baseline to both post-treatment and 3-month follow-up in severity of mental health functioning, factors interfering with sports …


Biomechanically-Consistent Skin Stretch As An Intuitive Mechanism For Sensory Feedback: A Preliminary Investigation In The Lower Limb, Jenny A. Kent Jan 2023

Biomechanically-Consistent Skin Stretch As An Intuitive Mechanism For Sensory Feedback: A Preliminary Investigation In The Lower Limb, Jenny A. Kent

Physical Therapy Faculty Publications

The proprioceptive loss accompanied by lower limb amputation can impair function and mobility. We explore a simple, mechanical skin-stretch array configured to generate superficial tissue behaviour that might occur with movement about an intact joint. Four adhesive pads attached around the circumference of the lower leg were connected via cords to a remote “foot” mounted on a ball joint attached to the underside of a fracture boot, such that “foot” reorientation would result in skin stretch. In two discrimination experiments performed with and without the connection, with no view of the mechanism, and with minimal training, unimpaired adults (i) estimated …


Exploring Gaps In City Climate Planning In The Mountain West, Joshua Padilla, Caitlin J. Saladino, William E. Brown Jr. Jan 2023

Exploring Gaps In City Climate Planning In The Mountain West, Joshua Padilla, Caitlin J. Saladino, William E. Brown Jr.

Environment

This fact sheet explores data from the 2022 Brookings Institution report by Joseph W. Kane, Adie Tomer, Caroline George, and Jamal Russell Black called “Not according to plan: Exploring gaps in city climate planning and the need for regional action." The original report analyzes decarbonization plans for 50 of the largest U.S. cities and comparatively ranks each plan using a point system of 5 categories. This fact sheet focuses on Mountain West cities (Denver, CO; Phoenix, AZ; Las Vegas, NV; Salt Lake, UT; and Albuquerque, NM) included in the original study.
