ABSTRACT We study the developmental and professional activities engaged in by 86 female adult soccer players from the senior national teams of Australia, Canada, England, Sweden, and the United States of America. Players completed the Participation History Questionnaire (PHQ) to elicit the amount and type of activities engaged in across their developmental and professional years, including milestones, soccer-specific activity and engagement in other sport activity. Greater specialisation than diversification characterised their childhood developmental activities, including all players starting in soccer in childhood and accumulating more hours in soccer activity than other sports during this period. However, interindividual variation further characterised these childhood activities, with a proportion of players diversifying into other sports and/or soccer play to a greater or lesser degree during childhood when compared to the other players. The amount of coach-led soccer practice increased for all players across their development culminating in an average of 15–16 h/wk across a 40-week season in early adulthood. In contrast, the amount of engagement in other sports and soccer peer-led play varied between players but generally decreased across adolescence to negligible amounts in late adolescence. Findings are commensurate with the deliberate practice framework and early engagement. 相似文献

Studies have reported an inverse association between language development and behavioral inhibition or shyness across childhood, but the direction of this association remains unclear. This study tested alternative hypotheses regarding this association in a large sample of toddlers. Data on behavioral inhibition and expressive and receptive language abilities were collected from 816 twins at ages 14, 20, and 24 months. Growth and regression models were fit to the data to assess the longitudinal associations between behavioral inhibition and language development from 14 to 24 months. Overall, there were significant associations between behavioral inhibition and expressive language, and minimal associations with receptive language, indicating that the association is better explained by reticence to respond rather than deficient language development. 相似文献

How can focus groups be used to examine issues of consequential validity in large-scale assessment? In relation to a new large-scale assessment, what are teacher concerns, and how do these concerns differ by type of school district? What are the strengths and weaknesses in this approach to looking at consequential validity? 相似文献

In this paper we described how we mixed research approaches in a Randomized Control Trial (RCT) of a school principal professional
development program. Using examples from our study we illustrate how combining qualitative and quantitative data can address
some key challenges from validating instruments and measures of mediator variables to examining how contextual factors interact
with the treatment. Describing how we transformed our qualitative and quantitative data, we consider how mixing methods enabled
us to deal with the two core RCT challenges of random assignment and treatment control critical. Our account offers insights
into ways of maximizing the potential of mixing research methods in RCTs. 相似文献

Identifying and evaluating the oldest published content held by the library using a set of transfer criteria provided a means to systematically evaluate and, if necessary, move rare or unusual content into a more secure location. The process enabled us to correct cataloging errors, identify and address items with condition issues, be familiar with the library's unique holdings and finally, to identify and add content distinctly associated with EMU's history to the University Archives and Special Collections. 相似文献
