Die Organisation sportlichen Erfolges

As the result of German efforts to advance elite sports being partially guided by the presumed successful example of the German Democratic Republic there has been an increase in vertically integrated sponsoring organizations to promote elite sports, particularly after reunification. Adhering to Williamson’s (1975) transaction costs economics, the theory is assessed that in producing sports success the effectiveness of hierarchical organizations depends on the specificity of production factors. Based on a comparison of former students of elite sports schools with non-elite students it could be shown that encouragement of talent in elite schools is advantageous in those types of sports that require specific sports locales or sites for practice. The results provide insight into how the productivity of elite sports schools could be enhanced.     

Sequence-dependent rotation axis changes in tennis

The purpose of this study was to evaluate the role of rotation axes during a tennis serve. A motion capture system was used to evaluate the contribution of the potential axes of rotation (minimum inertia axis, shoulder-centre of mass axis and the shoulder-elbow axis) during the four discrete tennis serve phases (loading, cocking, acceleration and follow through). Ten ranked athletes (International Tennis Number 1–3) repeatedly performed a flat service aiming at a target on the other side of the net. The four serve phases are distinct and thus, each movement phase seems to be organised around specific rotation axes. The results showed that the limbs’ rotational axis does not necessarily coincide with the minimum inertia axis across the cocking phase of the tennis serve. Even though individual serving strategies were exposed, all participants showed an effect due to the cocking phase and changed the rotation axis during the task. Taken together, the results showed that despite inter-individual differences, nine out of 10 participants changed the rotation axis towards the minimum inertia and/or the mass axis in an endeavour to maximise external rotation of the shoulder to optimally prepare for the acceleration phase.     

Stress-related psychological factors for back pain among athletes: Important topic with scarce evidence

Health issues represent a frequent problem for athletes, as this particular demographic is repeatedly confronted with physically and psychologically stressful situations. Back pain (BP) materialises as comparatively common health problem being regarded as functionally limiting and psychologically straining burden for athletes. According to research conducted on athletes with BP, biomechanical and physiological mechanisms emerge as influential, whereas stress-related psychological factors appear to be neglected. For athletic injuries, the essential impact of psychological processes on injury occurrence and return from injury has already been corroborated. Hence, the aim of this literature review is to: (1) introduce a conceptual differentiation between injuries and BP; (2) summarise the results obtained regarding stress-related psychological aspects for injuries; and (3) connect the injury research to the state-of-the-art evidence regarding stress-related factors for BP among athletes. A distinction between injuries and BP could be established based on previous definitions, despite the fact that a considerable overlap between both concepts prevails. Injuries can be attributed to a physical origin, whereas BP frequently lacks this physical criterion. For BP, our enquiry yielded four studies including psychological measures of stress – with two studies specifically examining the association between BP and psychological stress among athletes longitudinally. Abundant findings from the general population support the importance of considering psychological and specifically stress-related factors in BP prevention and rehabilitation, but evidence related to the athletic field remains elusive. Further scientific investigations with a wider methodological approach are needed to deepen the knowledge about the crucial relationship between psychological stress, BP, and athletes.     

Multiple mediation analysis of the relationship between rapid naming and reading

It is well established that rapid automatised naming (RAN) correlates with reading ability. Despite several attempts, no single component process (mediator) has been identified that fully accounts for the correlation. The present paper estimated the explanatory value of several mediators for the RAN–reading correlation. One hundred and sixty‐nine preschool students were given measures of RAN and additional measures of phonological awareness, lexical search speed, letter knowledge and paired associate learning. Their reading skills were tested a year later along with speed of processing. The influence of the mediators on the RAN–reading correlation was estimated as indirect effects in mediation analyses. Phonological awareness and letter knowledge significantly mediated the RAN–reading relationship, each accounting for a moderate part of the correlation between RAN and reading fluency. Thus, the RAN–reading correlation was partly, but not fully, accounted for by precursors of reading that are currently known.     

How to stay becoming – living up to the code of conduct in a sports class

In this article we show how a hybridisation of elite sport and school in lower-secondary education in Denmark produces a particular kind of learning subject with dual tracks for development, and we ask what kind of actions the students apply in order to stay becoming along both tracks. We apply theoretical conceptions of ‘becoming’ inspired by Brembeck and Johansson that allow us to understand how the sports students live up to the code of conduct of the sports classes. The article is based on an ethnographic study carried out in four schools located in four regions of Denmark. We argue that the hybrid obliges students to follow a narrow developmental track with an ambitious goal of performing in both sport and school, and that the hybrid is threatened when a sports student prioritises either sport or school while he/she is still enrolled in the class.

Social, ethical and technical issues in informatics—An integrated approach

This paper outlines a didactic approach for computer science courses based on the concept of socio-technical Informatics Systems, demonstrating the linkage between computational issues and their manifold social contexts as well as their close relation to social and ethical issues. The analysis of the product–process relationship of software development as a major element of the construction of Informatics Systems leads to the identification of important criteria for designing computer science courses. The selection of application areas as context types, of educational lenses, of methods and of media enables an integrated teaching approach. This kind of integrated approach offers an holistic approach to technical and societal aspects of an Informatics System in computer science education.     

Exemplarity,expressivity, education

ABSTRACT

This article proposes that Catherine Elgin and Nelson Goodman’s work on exemplification is relevant for discussions within moral philosophy and moral education. Generalizing Elgin and Goodman’s account of exemplification to also cover ethics, the article develops a two-factor account of moral exemplarity. According to this account, instantiation and expressivity are individually necessary and jointly sufficient conditions for someone or something to function as a moral exemplar. Applying this two-factor account of exemplarity to discussions within the philosophy of moral education the article then argues that it is the expressive aspect of moral exemplars, which explains and justifies the educational significance of such exemplars. The article concludes by discussing the similarities and differences between the expressivity account and the transparency criterion formulated by Michel Croce and Maria Silvia Vaccarezza in a recent paper.
