Effect of spanwise blowing on leading-edge vortex bursting of a highly swept aspect ratio 1.18 delta wing
An investigation was conducted in the Langley 1/8-scale V/STOL model tunnel on a semispan delta wing with a leading-edge sweep of 74 deg, to determine the effectiveness of various locations of upper surface and reflection plane blowing on leading-edge vortex bursting. Constant area nozzles were located on the wing upper surface along a ray swept 79 deg, which was beneath the leading-edge vortex core. The bursting and reformation of the leading-edge vortex was viewed by injecting helium into the vortex core, and employing a schlieren system
Understanding parental stressors: An investigation of British tennis-parents
This article was published in the Journal of Sports Sciences [Routledge (© Taylor & Francis)] and the definitive version is available at: http://dx.doi.org/10.1080/02640410802603871In this study, we examined the stressors experienced by British tennis-parents. The parents (n¼123) completed an extensive
survey focused on the internal and external demands that they had encountered through having a child compete in the sport.
The survey consisted of open-ended questions related to competition, coaching, organizational, personal, and developmental
issues. Inductive and deductive content analysis resulted in the development of seven core themes of tennis-parental stressor:
competition, coaches, finance, time, siblings, organization-related, and developmental. Parents experienced a diverse
number of competitive stressors indicating the particular difficulties they faced before, during, and after matches involving
their child, opponents, other parents, and officials. They also reported a wide range of organizational stressors that paralleled
the financial, social, and personal investments that accompanied their support roles. The results of this research reinforce the
importance of parents possessing the necessary skills to cope with the psychological, developmental, and logistical demands
of competitive tennis. Implications with respect to induction workshops and education for coaches and parents are
presented, as well as consideration for governing bodies to enhance their communication channels and logistical support.
Future research recommendations are posed to build upon the study of this domain in youth sport
