Verletzungen im Leistungssport aus soziologischer Perspektive

Injury in competitive sport is widely seen as a topic within the medical and psychological domain. This article gives an overview of sociological research on dealing with injury in competitive sport. Besides findings of a culture of risk, medical treatment practices and the governance of medical support systems, there are still many unanswered questions to which the sociology of sport could make a relevant contribution. Perspectives for future studies correspond with the social dynamics of injury, the structural role constraints in a medical treatment or rehabilitation context, and the governance of complex social networks for injury prevention, treatment and rehabilitation processes.     

Lexical and Sublexical Phonological Effects in Chinese Silent and Oral Reading

ABSTRACT

What is the time course of activation of phonological information in logographic writing systems like Chinese, in which meaning is prioritized over sound? We used a manipulation of phonological regularity to examine foveal and parafoveal phonological processing of Chinese phonograms at lexical and sublexical levels during Chinese sentence reading in 2 eye-tracking experiments. In Experiment 1, using an error disruption task during silent reading, we observed foveal lexical phonological activation in second-pass reading. In Experiment 2, using the boundary paradigm, both parafoveal lexical and sublexical phonological preview benefits were found in first-fixation duration in oral reading, whereas only lexical phonological benefits were found in gaze duration during silent reading. Thus, phonological information had earlier and more pronounced parafoveal effects in oral reading, and these extended to sublexical processing. These results are compatible with the view that oral reading prioritizes parafoveal phonological processing in Chinese.     

Vibrotactile feedback for correcting aerodynamic position of a cyclist

ABSTRACT

Guidance to maintain an optimal aerodynamic position is currently unavailable during cycling. This study used real-time vibrotactile feedback to guide cyclists to a reference position with minimal projected frontal area as an indicator of aerodynamic drag, by optimizing torso, shoulder, head and elbow position without compromising comfort when sitting still on the bike. The difference in recapturing the aerodynamic reference position during cycling after predefined deviations from the reference position at different intensities was analysed for 14 participants between three interventions, consisting of 1) vibrotactile feedback with a margin of error of 1.5% above the calibrated reference projected frontal area, 2) vibrotactile feedback with a margin of 3%, and 3) no feedback. The reference position is significantly more accurately achieved using vibrotactile feedback compared to no feedback (p < 0.001), but there is no significant difference between the 1.5% and 3% margin (p = 0.11) in terms of relative projected frontal area during cycling compared to the calibrated reference position (1.5% margin ?0.46 ± 1.76%, 3% margin ?0.01 ± 2.01%, no feedback 2.59 ± 3.29%). The results demonstrate that vibrotactile feedback can have an added value in assisting and correcting cyclists in recapturing their aerodynamic reference position.     

Ratings of usability of didactic models: a comparative case study in Croatia and Germany

The study refers to the unfavourable reputation and status of general didactics as well as its decreasing importance in teacher education. This is a result of poor performance achieved in international tests by students. They score low on knowledge and arguments, and empirical studies indicate that didactic models are useless. In view of the above problem, the aim of this article is to examine the validity of the argument that didactic models are useless. It is necessary to examine if general didactics are being in an unfavourable position along with its possible successors in the international context. In order to achieve that, we conducted an empirical study into the usability of didactic models for lesson planning in Croatia and compared it with the results obtained in previous research in Germany. The term usability means the advantages of theory in practice. On the basis of the results of the empirical study, we concluded that didactic models are not generally unusable. Additionally, they are different according to their usability. These results open a path for further research on this topic in the international context.     

Die Klasse an die Universit?t, die Masse an die anderen Hochschulen?

In Germany, different types of university-level institutions are available for tertiary education: traditional universities (Universit?ten) and??since the 1970s??universities of applied science (Fachhochschulen) as well as universities of cooperative education (Berufsakademien). The present study investigates differences in key areas related to students?? academic choices and success: do students at different types of university differ significantly in terms of cognitive performance, personality or social background? We compared N?=?1.230 students at traditional universities, universities of applied science, and universities of cooperative education (Baden-W??rttemberg Cooperative State University) on the basis of a large scale longitudinal study in the German federal state of Baden-W??rttemberg. Students of the different university types differed significantly in all three key areas (cognitive performance, personality, and social background) within the fields of technical sciences and economics. We determine the relative importance of these key areas for differences between university types and we discuss the implications of our findings.
