The purpose of this study was to compare performance factors of youth soccer players according to position. A total of 101 high school soccer players were selected and were classified into goalkeeper (n=7), defense (n=37), midfield (n=39), and forward (n=18) positions. All subjects were subjected to the Wingate test for anaerobic capacity, shuttle run test for aerobic capacity, and pass, kick, ...

We introduce skill chaining, a skill discovery method for continuous domains. Skill chaining produces chains of skills leading to a salient event—where salience can be defined simply as an end-of-task reward, or as a more sophisticated heuristic (e.g., an intrinsically interesting event (Singh et al., 2004)). The goal of each skill in the chain is to reach a state where its successor skill can ...

BMJ Qual Saf Published Online First: [please include Day Month Year] doi:10.1136/bmjqs-2015004439 Consistent with the emphasis on systems’ approaches that have characterised much of the patient safety movement thus far, most existing efforts aimed at improving surgical safety tend to focus almost exclusively on perioperative care. For example, surgical quality com...

Technical skill is mastery of complexity while creativity is mastery of simplicity .

The study aim was to compare expert with non-expert swimmers' rating of the aesthetic and technical qualities of front crawl in video-taped recordings of swimmers with low, middle, and high level proficiency. The results suggest that: i) observers' experience affects their judgment: only the expert observers correctly rated the swimmers' proficiency level; ii) evaluation of movement (technical ...

Existing research has established determinants of an IT-enabled strategy for competitive advantage which include IT Leadership, IT Skill, and IT Infrastructure (Sambamurthy 2000; Dehning and Stratopoulos 2003). Although research is emerging to demonstrate risk’s impact on competitive advantage, it still remains focused on mitigation and avoidance as its contribution (McGaughey et al. 1994). Thi...
