Utility Of International Normative 20 M Shuttle Run Values For Identifying Youth At Increased Cardiometabolic Risk, Duncan S. Buchan, Gareth Knox, Anwen M. Jones, Grant Tomkinson, Julien S. Baker

Education, Health & Behavior Studies Faculty Publications

The purpose of this study was to examine the ability of international normative centiles for the 20 m shuttle run test (20mSRT) to identify youth at increased cardiometabolic risk. This was a cross-sectional study involving 961 children aged 10–17 years (53% girls) from the United Kingdom. Receiver operating characteristic (ROC) curves determined the discriminatory ability of cardiorespiratory fitness percentiles for predicting increased cardiometabolic risk. ROC analysis demonstrated a significant but poor discriminatory accuracy of cardiorespiratory fitness in identifying low/high cardiometabolic risk in girls (AUC = 0.58, 95% CI: 0.54–0.63; p = 0.04), and in boys (AUC = 0.59, 95% CI: …

Using Self-Study As A Process For Teacher Inquiry Into Classroom Diversity, Aimee Rogers, Lisa Ortmann

Education, Health & Behavior Studies Faculty Publications

Educators in our region of the country likely agree that although there is growing diversity in our public schools in terms of culture, race, ethnicity, gender-identification, primary language and other aspects of diversity, the diversity of practicing and developing teachers has remained relatively unchanged. According to a national report, 82% of all undergraduate degrees in education across the country were awarded to white students in 2009-10, three-quarters of whom were women (AACTE, 2013). In our region of the upper midwest, the statistics are closer to 96% white and 73% female (North Dakota State University, 2017). Although as a teacher workforce, …

Career Decision Self‐Efficacy Of Transgender People: Pre‐ And Posttransition, Lore M. Dickey, Daniel Walinsky, Crystal Rofkahr, Kara Richardson‐Cline, Cindy L. Juntunen

Education, Health & Behavior Studies Faculty Publications

Although the mental health needs of transgender and gender‐nonconforming (TGNC) people have recently been addressed more directly than in the past (Bockting, Miner, Swinburne Romine, Hamilton, & Coleman, 2013; dickey, Reisner, & Juntunen, 2015; Meier, Pardo, Labuski, & Babcock, 2013), there remains a dearth of information related to vocational development of this population. Some of the considerations in career counseling and vocational development among TGNC people include differences in developmental concerns related to gender transition, gender presentation, passing (e.g., being perceived by others in one's affirmed gender), and binary and fluid gender identities (Beemyn & Rankin, 2011; Harrison, Grant, & …
