The effect of increased development and professionalization in elite Association Football referee training and the relationship with reduced home advantage in the English professional leagues were examined. The central aim was to chart the evolution of referee training, and how these developments in referee training have assisted in reducing home advantage. Interviews were conducted with elite and ex-elite referees, as well as those involved in the management, training and administration of elite referees in order to identify more recent adaptations to elite referee training and further explain the relationship between training and the reduction in home advantage. Findings indicate training and support is pronounced within elite refereeing has developed appreciably over time, and has contributed significantly to an increase in performance, decision-making correctness and subsequent decline in home advantage. 相似文献

- Digital preservation will never be a solved problem: it needs constant reinvention, and is going to become harder over time.
- Scholarship is changing and this is affecting what needs to be preserved and what preservation means to the future of knowledge discovery.
- The diversification of outputs means that knowledge exists in a network of contextual metadata, data, software, standards and publications—requiring multilateral management of this complex knowledge graph.
- Preservation demands new skills, technologies and resources from librarians, publishers, funders and institutions—and more joined-up thinking about archiving.
