We have developed and implemented the Relational Grid Monitoring Architecture (R-GMA) as part of the DataGrid project, to provide a flexible information and monitoring service for use by other middleware components and applications. R-GMA presents users with a virtual database and mediates queries posed at this database: users pose queries against a global(More)
It is well established that performance is influenced by pressure, but the underlying mechanisms of the pressure-performance relationship are poorly understood. To address this important issue, the current experiment evaluated psychological, physiological, and kinematic factors as mediators of the pressure-performance relationship. Psychological,(More)
We describe R-GMA (Relational Grid Monitoring Architecture) which is being developed within the European DataGrid Project as a Grid Information and Monitoring System for both the grid itself and for use by applications. Is is based on the GMA from GGF, which is a simple Consumer-Producer model. The special strength of this implementation comes from the(More)
Knowledge of the psychophysiological responses that characterize optimal motor performance is required to inform biofeedback interventions. This experiment compared cortical, cardiac, muscular, and kinematic activity in 10 experts and 10 novices as they performed golf putts in low- and high-pressure conditions. Results revealed that in the final seconds(More)
We describe R-GMA (Relational Grid Monitoring Architecture) which has been developed within the European DataGrid Project as a Grid Information and Monitoring System. Is is based on the GMA from GGF, which is a simple Consumer-Producer model. The special strength of this implementation comes from the power of the relational model. We offer a global view of(More)
Although it is well established that performance is influenced by competitive pressure, our understanding of the mechanisms which underlie the pressure-performance relationship is limited. The current experiment examined mediators of the relationship between competitive pressure and motor skill performance of experts. Psychological, physiological, and(More)
Quiet eye training expedites skill learning and facilitates anxiety-resistant performance. Changes in response programming and external focus of attention may explain such benefits. We examined the effects of quiet eye training on golf-putting performance, quiet eye duration, kinematics (clubhead acceleration), and physiological (heart rate, muscle(More)
