ABSTRACT This study examined the simultaneous effects of relative age and biological maturity status upon player selection in an English professional soccer academy. A total of 202 players from the U9 to U16 age groups, over an eight-year period (total of 566 observations), had their relative age (birth quarter) and biological maturity (categorised as late, on-time or early maturing based upon the Khamis-Roche method of percentage of predicted adult height at time of observation) recorded. Players born in the first birth quarter of the year (54.8%) were over-represented across all age groups. A selection bias towards players advanced in maturity status for chronological age emerged in U12 players and increased with age; 0% of players in the U15 and U16 age group were categorised as late maturing. A clear maturity selection bias for early maturing players was, however, only apparent when the least conservative criterion for estimating maturity status was applied (53.8% early and 1.9% late maturing in the U16 age group). Professional football academies need to recognise relative age and maturation as independent constructs that exist and operate independently. Thus, separate strategies should perhaps be designed to address the respective selection biases, to better identify, retain and develop players. 相似文献

This study examined the combined effect of character and policy coverage about a political candidate in news media on voters’ evaluations and thoughts about the candidate. A 2 (issue coverage: present/absent) × 2 (image coverage: present/absent) between-subject factorial experiment was conducted whereby participants (N = 134) read a version of an editorial article that varied in the coverage of a candidate’s character and policy positions. Results indicated that issue and image coverage, each in isolation, enhanced perceptions of the candidate’s image strength and issue strength. However, issue and image coverage when presented in combination compared to in isolation did not enhance perceptions of the candidate and in some cases hindered perceptions of candidate strength. When both coverage types were present, issue coverage dominated image coverage when participants formed image evaluations, whereas image coverage dominated issue coverage when they formed issue evaluations. Similar findings resulted for issue- and image-relevant thoughts. Implications about the effects of multicoverage political messages are discussed. 相似文献

This paper analyzes how major U.S. print and broadcast news media framed depression causal and problem-solving responsibilities at individual and societal levels over the past three decades. Results from the content analysis showed that the media placed more causal and problem-solving responsibilities on individuals than the society. However, references to societal solutions increased moderately over time. Organizational differences emerged in news attribution of responsibilities, as print media presented more individual-level causes while broadcast media focused more on solutions at both individual and societal levels. Additionally, local newspapers put more problem-solving responsibilities on individuals than national newspapers, while a cable news channel allocated more time to the discussion of overall depression responsibilities than network TV. Findings are discussed in the context of cultural orientations, organizational constraints, changing practice and trends in health news reporting, and the broader political/social environment in which the news media operate. Practical implications for health journalism, mental health communication and advocacy, and public health policy-making are discussed. 相似文献
