The purpose of the current study was to investigate how combinations of different epoch durations and cut-points affect the estimations of sedentary time and physical activity in adolescents. Accelerometer data from 101 adolescents were derived and 30 combinations were used to estimate sedentary time, light, moderate, vigorous, and combined moderate-to-vigorous physical activity. Data were analyzed with repeated measurement analyses of variance. Large differences of sedentary time and times of different physical activity intensities were observed between 1 s and longer epoch durations using virtually all cut-points. Generally, sedentary time, moderate physical activity, vigorous physical activity, and combined moderate-to-vigorous physical activity progressively decreased, whereas light physical activity increased with longer epoch durations. The extreme differences between cut-points were large and increased with longer epoch durations for sedentary time and for all physical activity intensities except for vigorous physical activity per epoch duration. Caution is required when cross-comparing studies using different epoch durations and cut-points. To accurately register adolescents’ spontaneous intermittent physical activity behavior, short epoch durations are recommended. 相似文献

Contemporary office work is becoming increasingly challenging as many routine tasks are automated or outsourced. The remaining problem solving activities may also offer potential for lifelong learning in the workplace. In this study, we analyzed problem solving in an office work setting using an Internet-based, semi-standardized diary to collect data close to the process. Thirteen employees in commercial departments of an automotive supplier participated voluntarily; they recorded 64 domain-specific problem cases in total. Typical problems were moderately complex but rather urgent. They were detected by means of monitoring, augmented feedback or feedback from others. The problems detected provoked states of high arousal, including both negative and positive emotions. We found that seeking support from others was the most common approach to problem solving, and that in general problem solving offered considerable learning possibilities. Experts were confronted with more complex problems than novices, they more often solved problems using their domain-specific knowledge, but they also preferred social support. Surprisingly, experts reported higher negative emotional states after having detected a problem than novices. The results, the diary method and the limitations of the study are discussed. 相似文献

The aims of our study were to compare the dominant (DOM) and non-dominant (NDOM) shoulders of high-level volleyball athletes and identify possible associations of shoulder adaptations with spike speed (SS) and shoulder pathology. A total of 22 male volleyball players from two teams participating in the first division of the Cypriot championship underwent clinical shoulder tests and simple measurements around their shoulder girdle joints bilaterally. SS was measured with the use of a sports speed radar. Compared with the NDOM side, the DOM scapula was more lateralised, the DOM dorsal capsule demonstrated greater laxity, the DOM dorsal muscles stretching ability was compromised, and the DOM pectoralis muscle was more lengthened. Players with present or past DOM shoulder pain demonstrated greater laxity in their DOM dorsal capsule, tightening of their DOM inferior capsule, and lower SS compared with those without shoulder pain. Dorsal capsule measurements bilaterally were significant predictors of SS. None of the shoulder measurements was associated with team roles or infraspinatus atrophy, while scapular lateralisation was more pronounced with increasing years of experience, and scapular antetilting was greater with increasing age. Adaptations of the DOM shoulder may be linked to pathology and performance. We describe simple shoulder measurements that may have the potential to predict chronic shoulder injury and become part of injury prevention programmes. Detailed biomechanical and large prospective studies are warranted to assess the validity of our findings and reach more definitive conclusions. 相似文献

In educational psychology, the concept of interest is interpreted as a content-specific motivational variable that can be investigated and theoretically reconstructed. An important analysis lies in the manifold interrelations between interest, learning and human development. This paper presents a “person–object theory of interest” and outlines developmental aspects such as: (a) the ontogenetic transition from situational to individual interest, (b) the relation between interest development and (c) the growing “self” and the assumption of a dual regulation system. 相似文献

Organisationsentwicklung und der Einsatz digitaler Medien in der Schule wurden bislang vornehmlich als zwei voneinander unabh?ngige Prozesse betrachtet. Dabei spielen Koordinations- und Abstimmungsmechanismen zwischen Schule und Schulbeh?rden sowie innerhalb der Schule aufgrund der Komplexit?t digitaler Medien eine wesentliche Rolle, wenn ein unterrichtsintegrierter Einsatz erreicht werden soll. Mit dem Vergleich der organisatorischen Einbettung digitaler Medien im Schulsystem dreier L?nder (Deutschland, USA und Gro?britannien) konnten Bedingungen bestimmt werden. die für eine nachhaltige p?dagogisch-didaktische Nutzung von Bedeutung sind. Nur durch ein Zusammenspiel von Organisations-, Personal- und Unterrichtsentwicklung auf der einen Seite und durch technisch-organisatorische Ma?nahmen (IT-Management) zur dauerhaften Sicherung des Betriebs und der Funktionsf?higkeit der IT-Infrastruktur auf der anderen Seite l?sst sich eine nachhaltige Gestaltung und Implementierung digitaler Medien in die Organisation Schule erreichen. 相似文献
