Kinematics and kinetics of handcycling propulsion at increasing workloads in able-bodied subjects

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 (P_max) 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.     

The Swedish riding school: a social arena for young riders

The aim was to explore how young riders experience the riding school. By analysing focus groups interviews, a picture emerged showing that young riders’ main motive for participating at riding schools was the social aspects. Riding schools could be characterized through an institutional perspective in which the young riders became internalized and socialized into a stable culture. The young riders identified with the norms and values of the riding instructors through master–apprentice learning. In addition, the results revealed a change in the stable culture since the instructors encouraged social interactions and participation in the community that became central to learning and development. Opportunities to influence and interact were important for the individuals and from a child’s rights perspective. Through participation in the community of practice at riding schools, young riders not only learn about riding and horse management but also develop important personal social skills.     

Measuring strategic processing when students read multiple texts

This study explored the dimensionality of multiple-text comprehension strategies in a sample of 216 Norwegian education undergraduates who read seven separate texts on a science topic and immediately afterwards responded to a self-report inventory focusing on strategic multiple-text processing in that specific task context. Two dimensions were identified through factor analysis: one concerning the accumulation of pieces of information from the different texts and one concerning cross-text elaboration. In a subsample of 71 students who were also administered measures of intratextual and intertextual comprehension after responding to the strategy inventory, hierarchical multiple regression analysis indicated that self-reported accumulation of information and cross-text elaboration explained variance in intertextual comprehension even after variance associated with prior knowledge had been removed.

Cross‐cultural Collaboration in Special Teacher Education: An arena for facilitating reflection?

The present study explored how cross‐cultural collaboration involving university lecturers from Norway (the North) and Egypt (the South), and student‐teachers from Egypt, can be an arena for facilitating student‐teachers’ reflection and for challenging student‐teachers’ preconceived beliefs and perspectives about disability and education. The findings, based on interview data, showed that an emphasis on reflection, exploration and evaluation rather than on drills and repetition was both unexpected and unfamiliar for most of the Egyptian student‐teachers. Some of the Egyptian and some of the foreign lecturers were able to encourage student‐teachers to reflect, although some of the foreign lecturers had a tendency to lecture as they had done at home. Lecturers who wanted to pursue teaching methods that enhanced reflection needed to prioritise time for this, even if the majority of the student‐teachers asked for more information, more facts and for presentations of “the right methods” for teaching learners with disabilities. As the findings in this study illustrate, the partner in the North carries a major responsibility for critically considering the request for expertise because the participants in the South may not necessarily question and challenge the authority of well‐educated professionals from the North. It may not be sufficient for lecturers and supervisors to be well‐qualified practitioners within their home culture. They should be context sensitive, have an inquiring and accepting attitude, and experience challenges, encounters and exposures in the project country over time. Competence in approaches in teacher education is also required, although this meta‐competence may not be explicitly requested by those concerned.     

Rhythm production at school entry as a predictor of poor reading and spelling at the end of first grade

Rhythm plays an organisational role in the prosody and phonology of language, and children with literacy difficulties have been found to demonstrate poor rhythmic perception. This study explored whether students’ performance on a simple rhythm task at school entry could serve as a predictor of whether they would face difficulties in word reading and spelling at the end of grade 1. The participants were 479 Norwegian 6-year-old first graders randomized as controls in the longitudinal RCT on track (n = 1171). Rhythmic timing and pre-reading skills were tested individually at school entry on a digital tablet. On the rhythm task, the students were told to tap a drum appearing on the screen to two different rhythms (2 Hz paced and 1.5 Hz paced). Children’s responses were recorded as they tapped on the screen with their index finger. Significant group differences were found in rhythm tapping ability measured at school entry, when groups were defined upon whether children went on to score above or below the 20th percentile reading and spelling thresholds in national assessment tests at the end of grade one. Inclusion of the school-entry rhythmic tapping measure into a model of classification accuracy for above or below threshold reading and spelling improved accuracy of classification by 6.2 and 9.2% respectively.     

Leading the teacher team — balancing between formal and informal power in program leadership

This continuous research within Nordic engineering institutions targets the contexts and possibilities for leadership among engineering education program directors. The IFP-model, developed based on analysis of interviews with program leaders in these institutions, visualizes the program director’s informal and formal power. The model is presented as a tool for starting a shared discussion on the complexities of the leadership of engineering program development. The authors liken program development to hunting in teams. Each individual expert in the program is needed, and all experts will need to work and collaborate for the same target. This calls for strategic and long-term thinking of engineering education development. Institutions should support the development of both formal structures as well as informal leadership skills among their program directors, but never fall for the temptation to see the program director as the only actor on the stage.     

Comparability of the Social Skills Improvement System to the Social Skills Rating System: A Norwegian Study

The Social Skills Improvement System-Rating Scales (SSIS-RS) is a multi-informant instrument assessing social skills and problem behavior in children and adolescents. It is a revised version of the Social Skills Rating System (SSRS). A Norwegian translation of the SSRS has been validated, but this has not yet been done for the Norwegian translation of the SSIS-RS. This study compared the Norwegian versions of the SSRS and the SSIS-RS administered to samples of children (aged 8–12 and 13–16?years) and their parents and teachers (n = 599). The results indicated moderate to strong relations between the common subscales across all forms of the two instruments and acceptable to excellent internal consistency across all common subscales. We conclude that the SSIS-RS is a good instrument for measuring social skills and problem behavior among children and adolescents in Norway.
