While an emerging body of research has examined the effects of school absences on student outcomes, there is comparatively little research examining the different reasons contributing to school absence, how common these reasons are, and the extent to which different types of absences are differentially associated with achievement. To address these gaps, we used data from the Longitudinal Study of Australian Children to examine the reasons for school absence as reported by 14–15 year olds and how these reasons relate to achievement outcomes in Year 9. Only 7% of 14–15 year olds indicated they had been absent in the previous six months without parental consent, of which 46% indicated the most recent absence was due to problems at school. Of the 90% of students who had been absent with parental consent, only 6% said the most recent absence was due to problems at school. After controlling for student, family and school characteristics and Year 7 achievement, Year 9 achievement was most strongly associated with absences related to student‐ or family‐level reasons. While schools typically bear the responsibility for monitoring and responding to absenteeism, the drivers of absence may not be related to factors that schools can realistically address. For schools, addressing absenteeism requires a dual approach of preventing avoidable absences and mitigation strategies for when either avoidable or unavoidable absences occur. 相似文献

In Paralympic sports, biomechanical optimisation of movements and equipment seems to be promising for improving performance. In handcycling, information about the biomechanics of this sport is mainly provided by case studies. The aim of the current study was (1) to examine changes in handcycling propulsion kinematics and kinetics due to increasing workloads and (2) identify parameters that are associated with peak aerobic performance. Twelve non-disabled male competitive triathletes without handcycling experience voluntarily participated in the study. They performed an initial familiarisation protocol and incremental step test until exhaustion in a recumbent racing handcycle that was attached to an ergometer. During the incremental test, tangential crank kinetics, 3D joint kinematics, blood lactate and ratings of perceived exertion (local and global) were identified. As a performance criterion, the maximal power output during the step test (Pmax) was calculated and correlated with biomechanical parameters. For higher workloads, an increase in crank torque was observed that was even more pronounced in the pull phase than in the push phase. Furthermore, participants showed an increase in shoulder internal rotation and abduction and a decrease in elbow flexion and retroversion. These changes were negatively correlated with performance. At high workloads, it seems that power output is more limited by the transition from pull to push phase than at low workloads. It is suggested that successful athletes demonstrate small alterations of their kinematic profile due to increasing workloads. Future studies should replicate and expand the test spectrum (sprint and continuous loads) as well as use methods like surface electromyography (sEMG) with elite handcyclists. 相似文献
