With reference to capital theories and rational choice theory, this paper aims to understand how abilities and schooling ambitions are intertwined with social class, gender and ethnicity. By drawing on 16 in‐depth interviews carried out with highly educated second‐generation Turks in the Netherlands, the paper discusses the resources, opportunities and educational attitudes of young people, together with the role of the school system and that of teachers in perpetuating ethnic inequalities in schooling, with special emphasis on gender differences in schooling ambitions. 相似文献

The decade 1997 to 2007 was a dramatic one for Ireland. Driven by a strong economy it had low rates of unemployment and attracted a large population of immigrant workers. These changes impacted directly on family life – most particularly in the area of the education and care of young children. The recent and equally dramatic change in economic circumstances has provided an unexpected context for a significant policy shift in early childhood care and education (ECCE) which, if carefully managed, could have profound effects on young children and their families. This article considers what recent Irish ECCE policy tells us about views of children and childhoods and where Ireland stands in respect of early childhood provision; it identifies some distinctly Irish tensions and considers what the likelihood is that recent policy initiatives mark a significant move forward for those seeking high quality ECCE provision for young children. 相似文献

This paper offers a comparative analysis of two characters belonging to the tradition of empowered “spinster” in children’s
fiction, namely Mary Poppins and Ms Wiz, from the perspective of gender politics and child/adult interactions. A distinction
is made between the figure portrayed in P. L. Travers’ texts and the Disney film starring Julie Andrews, which turned the
magic nanny into a cultural icon. These two renderings of the powerful, single woman, in turn, are contrasted with Terence
Blacker’s postmodern depiction of the good witch in the “Ms Wiz” series, with a view to tracing the evolution of the ostracised
female wizard, a character inherited from folklore that has its origin in the Great Mother archetype. As is demonstrated,
each representation of the supernatural woman modifies the manner in which the feminine influences the patriarchal order. 相似文献

The aims of this study were to measure the aerodynamic drag in professional cyclists, to obtain aerodynamic drag reference values in static and effort positions, to improve the cyclists' aerodynamic drag by modifying their position and cycle equipment, and to evaluate the advantages and disadvantages of these modifications. The study was performed in a wind tunnel with five professional cyclists. Four positions were assessed with a time-trial bike and one position with a standard racing bike. In all positions, aerodynamic drag and kinematic variables were recorded. The drag area for the time-trial bike was 31% higher in the effort than static position, and lower than for the standard racing bike. Changes in the cyclists' position decreased the aerodynamic drag by 14%. The aero-helmet was not favourable for all cyclists. The reliability of aerodynamic drag measures in the wind tunnel was high (r > 0.96, coefficient of variation < 2%). In conclusion, we measured and improved the aerodynamic drag in professional cyclists. Our results were better than those of other researchers who did not assess aerodynamic drag during effort at race pace and who employed different wheels. The efficiency of the aero-helmet, and the validity, reliability, and sensitivity of the wind tunnel and aerodynamic field testing were addressed. 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

Maximal oxygen uptake VO(2max)) is considered the optimal method to assess aerobic fitness. The measurement of VO(2max), however, requires special equipment and training. Maximal exercise testing with determination of maximal power output offers a more simple approach. This study explores the relationship between [Vdot]O(2max) and maximal power output in 247 children (139 boys and 108 girls) aged 7.9-11.1 years. Maximal oxygen uptake was measured by indirect calorimetry during a maximal ergometer exercise test with an initial workload of 30 W and 15 W x min(-1) increments. Maximal power output was also measured. A sample (n = 124) was used to calculate reference equations, which were then validated using another sample (n = 123). The linear reference equation for both sexes combined was: VO(2max) (ml x min(-1)) = 96 + 10.6 x maximal power + 3.5 . body mass. Using this reference equation, estimated VO(2max) per unit of body mass (ml x min(-1) x kg(-1)) calculated from maximal power correlated closely with the direct measurement of VO(2max) (r = 0.91, P <0.001). Bland-Altman analysis gave a mean limits of agreement of 0.2+/-2.9 (ml x min(-1) x kg(-1)) (1 s). Our results suggest that maximal power output serves as a good surrogate measurement for VO(2max) in population studies of children aged 8-11 years. 相似文献
