The primary purpose of this article is to provide an in-depth understanding of the manner in which surveillance technologies have become readily appropriated and utilised by elite Rugby Union coaches. It is conceded that positions adopted by populist writings commonly categorise the act of coaching as an educational activity that harnesses holistic intentions. Through reflecting upon semi-structured interviews with players located at an Aviva Premiership Rugby Union Club, we provide insight into an elite sporting institution that more accurately depicts coaching as a technocratic activity. The resultant analysis is critical in its review of surveillance mechanisms embedded in institutional practice, extending to the sports coaching setting, which explicate sinister rather than pastoral motives to enforce a disciplinary power that enhances the quantification of athletic performance. The article concludes by emphasising the impact of such practices upon establishing a sense of trust and the construction of self autonomous to the sporting domain. We argue that the emerging and steadfast acceptance of technology in the elite coaching environment is threatening to circumvent the learning potential of players by merely viewing them as functionaries. In adopting this position, we tentatively suggest that future research seeking to inform the practice of coaching and coach education should continue to pursue this critical dialogue to question whether, and to what extent, an overreliance on technology is becoming perceived as the ‘gold standard’ of professional practice amongst the coaching fraternity. 相似文献

The current study examines the association between parental support and adolescent sleep under varying levels of family stress. Participants included 316 adolescents (Mage = 16.40 years, 43% male) and their parents (Mage = 45.67 years, 91% mothers) from diverse ethnic backgrounds. Both adolescents and parents completed questionnaires and adolescents wore wrist actigraphs and completed self‐reports on their sleep for 7 consecutive days. Results indicated that under contexts of family stress, more parental support was linked to longer sleep duration, less sleep variability, and less time spent awake during the night. Findings suggest that under contexts of family stress, cohesive family relationships may provide a sense of stability and security that is necessary for healthful sleep. 相似文献

This paper describes an ongoing process of participatory curriculum development. It outlines some of the tensions which need
to be explored in science curriculum development: debates about the nature of science, of society, of school science content
and of learning theories. The process whereby action can arise from this debate is also explored. An example will be outlined
of a network of science curriculum action which has developed from the work of a range of science education projects in Natal,
South Africa.

INTRODUCTION Since the phenomenon of piezoelectricity in natural crystals was discovered in 1880, it has been applied in many fields, such as smart structure, sensing devices and active control, because of its special properties. Combining electrical behavior with mechanical deformation is the special property which attracted great interest of researchers. Many models have been developed for studying piezoelec- tric effects. Dunn and Wienecke (1996) used Green’s functions for transverse… 相似文献
