In the present study, we examined the performance environment of the England youth soccer teams. Using a semi-structured protocol with a prospective sample, national coaches (n = 6), sport scientists (n = 3), and players (n = 4) were interviewed directly following international tournaments about the factors that positively and negatively influenced performance. Qualitative content analysis revealed the following factors as major positive influences on performance: adhering to a consistent tournament strategy, player understanding, strong team cohesion, organized entertainment activities, detailed knowledge of opposition, an effective physical rest/recovery strategy, and previous tournament experience. Major factors perceived to have negatively influenced performance included: over-coaching, player boredom, player anxiety, physical superiority of the opposition, physical fatigue over the tournament, problems sleeping, and lack of information on the opposition. Eight overall dimensions emerged to describe the performance environment: planning and organization, physical environment, tactical factors, development and performance philosophy, psychological factors, physical factors, social factors, and coaching. The findings support recent work that suggests the performance environment is multifaceted, with performance being contingent upon a broad range of interacting factors that go beyond the traditional psychosocial and physical domains. 相似文献

In this paper we introduce the concept of a Prolog programming technique. This concept is then distinguished both from that of an algorithm and that of a programming cliché. We give examples and show how a knowledge of them can be useful in both programming environments and in teaching programming skills. The extraction of the various techniques is outlined. Finally, we discuss the problem of representing techniques where we conclude that the most promising approach is the development of a suitable meta-language. 相似文献

This study uses qualitative interviews with 66 women journalists from print, broadcast, and online media in India, to understand how women political reporters assigned to the political beat negotiate gender issues and organizational and news routines while being effective journalists entrusted to cover matters of policy and enhance political awareness among audiences. Using Shoemaker and Reese’s hierarchy-of-influences model that introduces five levels of influence on news content, this study explores how institutional, news gathering, societal procedures, and professional practices influence the functions of women journalists on the political beat and percolate into the content they produce. The results show that in India’s growing media market, organizational and news routines, as well as the contentious issue of gender, control access to beats, especially the political beat, and percolate into news content produced by women political reporters. 相似文献

Relative age effect in Spanish association football: its extent and implications for wasted potential 总被引：1，自引：1，他引：0
Spain is one of the largest and most successful powers in international youth football, but this success has not extended to the national team. This lack of continued success seems to indicate a loss of potential. The relative age effect has been detected in football in many countries. Understanding the extent of this bias in the youth teams of Spanish elite clubs may help to improve selection processes and reduce the waste of potential. Comparisons between players from: the Spanish Professional Football League, all age categories of these clubs' youth teams, the Under-17 to Under-21 national teams, the national team, and the Spanish population, show a constant tendency to under-represent players from the later months of the selection year at all age groups of youth and Under-17 to Under-21 national teams. Professional and national team players show a similar but diminished behaviour that weakens with ageing, which suggests that talent identification and selection processes can be improved to help better identify potential talent early on and minimize wasted potential. 相似文献

We examined the performance environment of the England youth soccer teams. Using a conceptually grounded questionnaire developed from the themes identified by Pain and Harwood (2007), 82 players and 23 national coaches and support staff were surveyed directly following international tournaments regarding the factors that positively and negatively influenced performance. The survey enabled data to be captured regarding both the extent and magnitude of the impact of the factors comprising the performance environment. Overall, team and social factors were generally perceived to have the greatest positive impact, with players and staff showing high levels of consensus in their evaluations. Team leadership and strong team cohesion were identified by both groups as having the greatest positive impact. Overall, far fewer variables were perceived to have a negative impact on performance, especially for players. The main negatives common to both groups were players losing composure during games, player boredom, and a lack of available activities in the hotel. The major findings support those of Pain and Harwood (2007) and in using a larger sample helped to corroborate and strengthen the generalizability of the findings. 相似文献

The investigation probed relationships among human‐figure drawing, field‐dependent‐independent cognitive style and self‐esteem of 10–15 year olds. It also attempted to predict human‐figure drawing scores of participants based on their field‐dependence‐independence and self‐esteem. Area, stratified and multi‐stage random sampling were used to select a sample of 600 10–15 year olds residing in Kolkata city, India. The sample comprised three age‐based strata: 10 and 11 year olds; 12 and 13 year olds; and 14 and 15 year olds. Each stratum comprised 100 girls and 100 boys. Participants’ actual age‐ranges were 10 years 1 month – 11 years 10 months (first stratum); 12 years 4 months – 13 years 10 months (second stratum); and 14 years 3 months – 15 years 9 months (third stratum). Goodenough‐Harris Drawing Test, Group Embedded Figures Test and Coopersmith Inventory were administered for assessing participants’ human‐figure drawing, field‐dependence‐independence and self‐esteem respectively. Results revealed significant positive relations among pertinent variables. Participants’ human‐figure drawing scores could be significantly predicted by their field‐dependence‐independence and self‐esteem. 相似文献
