Measurement Uncertainty
Get PDFThis text is based on the graduate Measurements course notes from BLS at Utah State University. It is intended as a textbook for graduate students in engineering or physics or as a reference text.
If one collects several texts on measurement uncertainty, it quickly becomes clear that the measurement uncertainty community lacks a consistent language or nomenclature. This can be confusing to a new reader who may view measurement uncertainty as a very old and settled topic. The lack of consensus on nomenclature likely stems from the lack of a clear winner–a paradigm and nomenclature set sufficiently superior to be adopted by everyone. It is our hope that this book will improve on previous texts.
In addition, this text will attempt to move beyond traditional thinking about measurement uncertainty that is limited to point measurements and uncertainties that are either fixed or linearly related to the reading. With a special focus on camera-based measurements and their unique issues, it is our ambition to write the first modern measurement uncertainty text.
The authors wish to acknowledge a debt to Hugh Coleman and Glenn Steele and their 3rd edition text [1], which made progress in the directions that we hope to continue; towards a richer and more realistic uncertainty analysis that considers material property uncertainties as well as the positive and negative impacts of correlated uncertainties. This text was later revised into the 4th edition [2], which added some small but significant changes.
Additionally, the authors would like to thank many individuals who gave specific input. Steve Beresh and Randy Hurd were kind enough to provide a very comprehensive review of the text. Geordie Richards guided us through several issues with respect to statistics. Alan Nathan reviewed some of the baseball examples and Bill Zwolinski engaged in many fruitful conversation about instrument specifications. Finally, BLS would have never been interested in this topic without the excellent mentorship of Dr. Greg Swift of Los Alamos National Laboratories
Sevier County Adventures - Poster Presentation
No full textThe Sevier County Adventures is a community engagement series of events that are fun for all and center on 4 community-identified needs; mental health, substance abuse, suicide, and parenting/family relationships. Once a quarter in 2025, the USU Sevier County Extension Office and the Central Utah Health Department, in conjunction with other entities, will hold community events to provide resources and information that highlight a specific need from the 4 community-identified needs. 1-Mental Health Game Night – Participants will be given a resource packet with information on local providers and teams will play an escape room game box. 2-Home Run for Safety – In partnership with the Emergency Preparedness Coordinator, the community will learn first aid safety skills through a baseball game and receive information on substance abuse. 3- Star Party for Suicide Awareness – In partnership with the Central Utah American Foundation for Suicide Prevention, the community will engage in a Walk out of the Darkness event. 4-Screen Free Family Party- This event will be an invitation to keep phones and distractions away and bond as a family. Expected outcomes include more community engagement on these issues in the future, and connection with priority populations in Sevier County
The Do-It-Yourself Guide to Backyard Drip Irrigation
Get PDFThis guide promotes efficient backyard drip irrigation as a vital strategy for water conservation in Utah, the third-driest state in the U.S. It explains evapotranspiration (ET), drip system components, and provides formulas to calculate a plant’s water needs. The guide provides practical advice on converting traditional irrigation systems to drip systems, particularly in flower beds and around shrubs and trees. By implementing drip irrigation, homeowners can contribute to water conservation while enhancing the health of their landscapes

Audiological Characteristics and Associations With Psychological Inflexibility
No full textPurpose: The aim of this study was to describe psychological inflexibility for hearing difficulty for a sample of adults seeking hearing help and explore associations with demographic and audiological characteristics. Method: Archival data from 226 clinical electronic medical records at one university clinic were analyzed for this retrospective exploratory study. Audiometric test findings and results from the Acceptance and Action Questionnaire–Adult Hearing Loss (AAQ-AHL) were extracted for adult patients seen between June 1, 2022, and February 29, 2024. Results: The majority had a bilateral hearing loss (64%), 10% had a unilateral hearing loss, and 26% had bilateral pure-tone averages better than 25 dB HL. The AAQ-AHL total scores ranged from 0 to 51, and 8% had a high likelihood of distress from internal struggles related to their difficulty hearing. On individual items, up to one third of the sample expressed internal challenges. The AAQ-AHL total scores were moderately correlated with word recognition in noise, weakly correlated with better ear pure-tone average and word recognition in quiet, and were not correlated with age. Conclusions: The current study adds to the previous research describing psychosocial challenges that can be experienced by people with hearing difficulties. Our research demonstrates that psychological inflexibility for hearing loss can be experienced by individuals of all ages and hearing status. Based on the present findings, we recommend that audiologists intentionally assess for psychosocial challenges for people seeking hearing help
Challenging the Gaze: A Feminist Interpretation of the \u3ci\u3eS.M.S.\u3c/i\u3e Mail Art Collection
Get PDFIn the late 1960s, many people called for radical, immediate change to America’s political, societal, and cultural structures. The artistic practices of the time reflected the social and political realities of the moment and played a crucial role in advocating for change. The title of the 1968 S.M.S. (Shit Must Stop) subscription art portfolios was a bold and urgent call for action, challenging artists and audiences alike to confront the pressing injustices of the era and inspire a collective awakening to the necessity of transformative change across the United States. Despite a fifty-six-year gap, today we are still fighting the same social and political battles that influenced many of the artists included in the S.M.S. art portfolios. This collection of six portfolios serves as a compelling visual reflection of the socio-political dynamics of the late 1960s, capturing the era\u27s tensions, ideologies, and cultural shifts through the artists’ innovative use of form, content, media, and display
Electromyographic Analysis of Lower Limb Muscles During Multi-Joint Eccentric Isokinetic Exercise Using the Eccentron Dynamometer
Get PDFEccentric muscle actions are integral to human movement, rehabilitation, and performance training due to their characteristic high force output (overload) and low energy cost and perceived exertion. Despite the growing use of eccentric devices, a gap in the research exists exploring multi-muscle activation profiles during multi-joint eccentric-only, isokinetic exercise. This study aimed to quantify and compare surface electromyographic (EMG) activity of four leg muscles—vastus lateralis (VL), tibialis anterior (TA), biceps femoris (BF), and medial gastrocnemius (GM)—during a standardized (isokinetic) submaximal eccentric multi-joint exercise using the Eccentron dynamometer. Eighteen healthy adults performed eccentric exercise at 40% of their maximal eccentric strength. Surface EMG data were analyzed using root mean square (RMS) and integrated EMG (iEMG) variables. Repeated-measures ANOVAs and effect sizes (ES) were used to evaluate within-subject differences across muscles. Results showed significantly greater activation in the VL compared to all other muscles (p \u3c 0.05; and ES of 1.28–3.17 versus all other muscles), with the TA also demonstrating higher activation than the BF (p \u3c 0.05). The BF exhibited the lowest activation, suggesting limited hamstring engagement. These findings highlight the effectiveness of the multi-joint isokinetic eccentric leg press movement (via an Eccentron machine) in targeting the quadriceps and dorsiflexors, while indicating the possible need for supplementary hamstring and plantar flexor exercises when aiming for a comprehensive lower body training routine. This study provides important insights for optimizing eccentric training protocols and rehabilitation strategies
Declining Democracy Amid Historical Legacies: Democratization Across the Maghreb
No full textInstitutions and security forces are vital in determining democratization’s success or failure, but how do they interact with civilians to counteract, or support, existing regimes? Hopes for a fourth wave of democratization were dismantled over the past decade as the Arab uprisings have had inconclusive results, posing a threat to the ideological basis for U.S. foreign policy and Western states\u27 legitimacy. Broad economic and Western foreign policies applied worldwide over the past few decades have also been ineffective at supporting this process and producing sustainable democratic transitions. But what specifically about these factors in the Maghreb gave way to Tunisia’s success while Morocco and Algeria underwent limited reforms and authoritarian consolidation? Furthermore, what aspects of institutions and security forces influence governance, and how do colonial legacies perpetuate their power? I argue that institutions and colonial histories alter how security forces and mass mobilization interact to produce democratic consolidation throughout the Maghreb region after the 2011 Arab uprisings. I focus on three causal mechanisms: the power of a country’s military in politics, civilian support of a country’s governing institutions, and the structure of French colonial administrations to support these processes. Within these three mechanisms, I develop an Ordinary least squares model that suggests an association between higher support for democracy and increasing civilians’ trust in state institutions. Results suggest that building support for democracy at a grassroots level within foreign policy is the most effective way to increase the likelihood of democratization amid existing institutions
