Single Vs. Whole Muscle Group Assessments: Does The Specific Muscle Influence Its Association With Performance?
No full textTopics in Exercise Science and Kinesiology Volume 6: Issue 1, Article 11, 2025. Biometric Muscle size and echo intensity are thought to influence muscle function. Unfortunately, previous works often will examine a single muscle from a group of agonists as a metric of whole muscle performance. This approach may not always be the most appropriate to assess performance outcomes. The purpose of the study was to 1) quantify the association of muscle size and echo intensity with vertical jump performance (VJ), 2) Compare the associations between individual and whole muscle group size and echo intensity, 3) determine whether single or whole muscle size and echo intensity better predicted VJ performance. Nineteen adults (214 years) completed one visit to the laboratory for musculoskeletal imaging and vertical jump testing. B-mode ultrasound images of the vastus lateralis, vastus intermedius, vastus medialis, and rectus femoris muscles were acquired; CSA and echo intensity were quantified via offline analysis. Pearson’s product moment correlation coefficients (r) were calculated to determine association between individual and whole muscle size and echo intensity with VJ performance. Steiger’s z procedures were used to examine differences in correlations between individual muscles and total quadricep relationships to VJ. Follow-up stepwise multiple linear regressions were used to predict the individual and whole muscle association with VJ performance. The results suggested that muscle size but not echo intensity, may be associated with VJ. Steiger’s z procedures did not reveal differences in quadricep and individual muscle CSA with VJ performance. Furthermore, the CSA of the vasti musculature, but not the RF, had a meaningful impact on VJ
Homelessness Among School-Aged Children in the Mountain West, 2022-2023
No full textThis fact sheet presents data on homelessness among school-aged children in the Mountain West during the 2022-2023 school year. The data are sourced from the “Child and Youth Homelessness in the United States: Data Profiles” dashboard produced by SchoolHouse Connection and Poverty Solutions at the University of Michigan. State-level data profiles include information about child and youth homelessness at the national, state, county, school district, and congressional district levels. This fact sheet focuses on homelessness among school-aged children within the Mountain West states of Arizona, Colorado, Nevada, New Mexico, and Utah
Design and Assembly of a Lightweight, Multi-Cannula Tetrode Drive for Bilateral Hippocampal and ACC Recordings
No full textImplants and Electrophysiology:
Electrophysiology is the study of the electrical properties of cells and tissues, neuronal implants enable high-resolution recordings of neuron action potentials and their locations in the brain.
Data gathered is key in investigating/mapping cognition and effects of neurological pathologies on regular neural systems.
Hyperdrive Model:
Previous model was restricted to two implant sites, and displayed frequent tetrode deformation
Hyperdrive was modified to support four implant sites and 16 independently movable tetrodes using 3D modeling software, while keeping its weight below 1.5 grams.
Targets:
Researchers targeted the hippocampus (CA1, CA3) and ACC, using the novel bilateral modelhttps://oasis.library.unlv.edu/durep_posters/1252/thumbnail.jp
Relationship Closeness and Eating Disorder Pathology in Undergraduate Female Friends Dyads

Impact of Remote Work on Wages in Nevada’s Labor Force
No full textRemote Work Evolution and COVID-19 In 2019, 7% of full paid workdays were done remotely. During the pandemic, that number substantially grew to 60%, and by 2023 it shrunk down to 28%. Elements of remote work have even spread to multiple industries such as healthcare, finance, and education (Barrero et al., 2023). Direct relationship between self-perceived job performance and remote work productivity. However, living with children under 18 negatively impacts remote work engagement and productivity (Toscano & Zappalá, 2021). Remote work can be associated with increases in Total Factor Productivity (TFP). Between 2019 and 2021, a 1% increase in the share of remote workers was associated with a 0.08% increase in TFP growth (Pabilonia & Redmond, 2024). Employment loss in STEM was noticeably lower during the pandemic compared to other fields. The greater feasibility of remote working within STEM occupations compared to other fields may have contributed to this result (Davis et al., 2021).https://oasis.library.unlv.edu/durep_podium/1059/thumbnail.jp
Analyzing Healthcare as a Right, Instead of a Privilege
No full textHealthcare is a fundamental necessity, yet in many countries including the United States, it remains a privilege rather than a right. This research examines the benefits of universal healthcare by analyzing its impact in countries that have successfully implemented healthcare such as Canada, the United Kingdom, and Germany. This study evaluates the healthcare accessibility, cost efficiency, and health outcomes in these countries against the U.S. This finding will suggest that universal health care leads to lower overall healthcare costs, improve public health, and reduce financial burdens on individuals. By ensuring healthcare as a right, rather than a privilege, the U.S would enhance its economic stability and societal well being. This research will support the argument that adopting a universal health care model will create a more efficient healthcare system.https://oasis.library.unlv.edu/durep_podium/1064/thumbnail.jp
Flexing in Popular Songs From 2024 - 2023
No full textPurpose:
Music is a major agent of socialization. As an art form, music carries with it messaging and rhetoric capable of reaching people en masse. With this in mind, it is vital that we pay a careful eye to music in order to understand what messaging is reaching the public at large. This project is intended to build off of the current literature on music, rhetoric, and socialization by understanding what artists in music brag about - flex - as a means of gaining cultural capital.https://oasis.library.unlv.edu/durep_podium/1065/thumbnail.jp
Competence Protein ComEA and Oxidative Stress in Bacillus subtilis Stationary Phase Mutagenesis
No full textStationary Phase Mutagenesis is a process where a bacterium can accumulate mutations in the absence of cell division. This may occur via competent DNA uptake and oxidant DNA damage and repair. ComEA is a transmembrane protein in B. subtilis that is required for the transport of exogenous DNA into the cell.
