ABSTRACT

This study investigates the spatial relationship of performance variables for soccer free kicks. In order to suggest ways in which players might optimise their performance, we collected data from free kicks (<35 m to goal line) of two German Bundesliga seasons (2013/14, 2014/15) (n = 1624). In the analysis, we applied the ISO-map approach using colour gradients to visualise the mean values of a variable on a 2D-map of the pitch. Additionally, variograms were used to describe the degree of spatial dependence of the free kick variables. Results show that DENSITY, TYPE OF PLAY, PLAYERS IN WALL, DISTANCE TO WALL and RULE VIOLATION were strongly spatially dependent. Centrality and proximity to the goal increased the variables PLAYERS IN WALL, RULE VIOLATIONS and INTERRUPTION TIME, and the ratio of goals scored increased from 5.9% (central far) to 10.9% (central near). In 70.9% of the shots, players preferred a switched laterality, which did not result in a higher success rate. Furthermore, there was no statistical advantage for the defensive team when DISTANCE TO WALL was below 9.15 m or when there was a RULE VIOLATION. Crosses had a success rate (i.e., first controlled ball contact after the cross) of 20.8%. Played with natural laterality, they were 5% more successful than with switched laterality. Crosses from the right side outside the penalty box were 10% more successful than from the left side. Therefore, it might be worthwhile practising the defence of balls coming from this side.  相似文献

Zusammenfassung. Traditionelle und deduktive Informationssysteme werden heute immer noch isoliert voneinander modelliert und implementiert. Für die meisten Benutzer sind jedoch Systeme wichtig, die ihren allt?glichen Informationsbedarf decken und darüber hinaus deduktive F?higkeiten besitzen. Der bekannte Entity-Relationship-Ansatz zur konzeptionellen Datenmodellierung wird in dieser Arbeit so erweitert, da? damit solche integrierten Systeme modelliert werden k?nnen. Au?erdem wird eine Klassifizierung ableitbarer Daten eingeführt, die dem Analytiker Hilfestellung bei der Frage gibt, welche ableitbaren Daten bei der Modellierung berücksichtigt werden sollen und welche nicht.

Practical training and internships in engineering education: Educational goals and assessment     

Otto Rompelman  Jan De Vries 《European Journal of Engineering Education》2002,27(2):173-180

In many engineering curricula a period of practical training in industry is either compulsory or advised. Often the educational goals of such a period are defined as 'learning to put knowledge and skills into practice'. The assessment is usually based on a technical report of the activities during the period. In this paper, how the definition of educational objectives led to the introduction of practical training is discussed. These objectives are acquiring insight in the engineering profession, learning to 'survive' in a different culture and learning to apply as well as broadening technical knowledge and skills. Furthermore, an assessment procedure is introduced which allows for testing whether the students have met the objectives.  相似文献
