A topography of free kicks in soccer

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.     

Language approaches used with deaf pupils in Scottish schools: 2001-2004

In this article we address "language approach" data as a key variable in quantitative, large-scale research on educational achievement, focusing on our work for the Achievements of Deaf Pupils in Scotland (ADPS) project. The complexity of approaches is addressed, with a particular focus on a "no-exclusion" model of service. In this context 3 years of language-related data are discussed, using constructions of language variables that take into account the variability in deaf pupils' hearing loss levels, types of provision, and professional practice. We see this as a necessary first step toward offering a nuanced context for understanding patterns in the educational outcomes among the ADPS population to be reported in a later article. The ADPS data on language approach can reveal general patterns at macro levels: our analysis suggests that, in Scotland, the extent and quality of British Sign Language/English provision may be determined more by local factors than by linguistic requirements and that ostensibly responsive policies can mask a limited spectrum for pupils and their families. However, the ADPS data are insufficiently sensitive to detailed and local variations to reflect the full complexity of language situations over time-a situation which represents an ongoing challenge for all long-term, large-scale studies.     

Changing and/or reinscribing gendered discourses of team leadership in education?

In this article, prevailing professional, business and managerial discourses of team leadership are ‘troubled’ by some feminist critiques and analyses of collectivity and gendered discursive relations of power. I draw on a study of primary school co‐principalships to describe and reflect on Karen’s (a pseudonym) accounts of her personal and shared leadership practices within a three teacher co‐principalship. The article indicates how feminist consciousness, politics and relationships can contribute to social, cultural and organizational change within ‘mainstream’ institutions. ¹ 1. I am grateful to the reviewers of this article, one of whom made this point. View all notes It also explores how pre‐constructed discourses about gender, class and leadership, can be unwittingly stitched back into an individual’s collaborative practices, limiting the potential for democratic change. My aim is to contribute to the kind of work called for by Davies when she argued that if we are alerted to the work being done by the various discourses we are invoking, then we can more effectively reflect on how limiting and disempowering discursive constructions can be challenged and changed.     

Self-instruction training: A potential tool for school psychologists

Self-instruction training is a cognitive-behavioral approach to self-control in which children are taught to use covert speech to modify their own behavior. The potential effectiveness of self-instruction training as an intervention technique for school psychologists to enhance student academic and/or social behavior in the classroom is the focus of this review. Research results addressing the practical issues of how, when, and with whom to use this strategy, its generalizability, and its long-term and comparative effectiveness are presented. Implications for further research in the schools are discussed.
