Students’ perceptions of school safety and experiences with bullying were examined in a large Canadian cohort of 5,493 girls and 5,659 boys in Grades 4 to 12. Results indicate notable differences in when and where students felt safe based on their own perceptions of safety and their own experiences with bullying, particularly across elementary and secondary schools. For elementary students, especially those involved in bullying, the playground/school yard and outside recess/break time were particularly hazardous, whereas for secondary students involved in bullying, the hallways, school lunchroom/cafeteria, and outside recess/break were considered especially dangerous. The commonality across student-identified unsafe areas is that they tend to not be well supervised by school personnel. Accordingly, the present results underscore the need to increase adult supervision in areas in which an overwhelming majority of students report feeling unsafe.

Objective:(1) Compare rates of abnormal screening electrocardiograms (ECGs) using updated criteria compared with older criteria. (2) Compare rates of abnormal ECGs by ethnicity. (3) Evaluate ability of ECG criteria to detect the predicted number of athletes with previously undetected cardiovascular abnormalities.Design:Prospective and retrospective review of ECGs. During the prospective portion of the study, the 2005 European Society of Cardiology criteria were used from 2008 to July 2011 and the 2011 Stanford criteria were used from August 2011 to 2013. Retrospectively, all ECGs were reevaluated using the 2011 Stanford criteria, 2013 Seattle criteria, and 2014 Sharma Refined criteria.Setting:Division I National Collegiate Athletic Association University.Participants:874 incoming athletes over a 5-year period.Interventions:ECG screening program.Main Outcome Measures:Number of abnormal ECGs and number of athletes with newly discovered cardiac abnormalities.Results:Abnormal ECG rates were the 2005 European criteria 10.7%, 2011 Stanford criteria 6.6%, 2013 Seattle criteria 2.8%, and 2014 Sharma Refined criteria 2.8%. In black athletes, the Stanford criteria resulted in more abnormal ECGs compared with Seattle or Sharma Refined. Three athletes were found to have a previously undetected cardiac abnormality (2 with hypertrophic cardiomyopathy and 1 with preexcitation).Conclusions:More recent ECG screening criteria substantially reduce the abnormal ECG rate and thus the number of athletes requiring additional testing. ECG screening criteria identified the predicted number (1/300) of young athletes with serious underlying cardiovascular disease. These criteria prompt not only additional cardiovascular testing but also a more thorough cardiovascular history.

Social media platforms aspire to deliver fair resolutions after online harassment. Platforms rely on sanctions like removing content or banning users but these punitive responses provide little opportunity for justice or reparation for targets of harassment. This may be especially important for youth, who experience pervasive harassment which can have uniquely harmful effects on their wellbeing. We conducted a text-message based survey with 832 U.S. adolescents and young adults, ages 14-24, to explore their attitudes towards social media companies' responses to online harassment. We find that youth are twice as likely (41% versus 20%) not to trust social media companies' ability to achieve a fair resolution as they are to trust them. Nearly two-thirds (62%) of youth expressed a preference for an apology from the offender after online harassment, and they were twice as likely to prefer a private apology to a public one (29% versus 14%). Preferences also vary by identity, revealing how a one-size-fits-all approach can harm some youth while benefitting others. We reflect on the opportunities and risks associated with institutional trust and restorative justice for supporting youth who experience online harassment.
