Here we present the case of a 20-year-old male with a known history of an artificial mechanical aortic valve replacement at ages four and twelve, on chronic warfarin therapy, who presented to our community emergency department for the evaluation of vomiting, diarrhea, generalized malaise and abdominal pain. He was seen at a local urgent care for similar symptoms earlier in the day, subsequently discharged with a diagnosis of mild gastroenteritis; however, according to the patient＇s sister, upon his return home he looked very unwell and she called an ambulance immediately.

Fifty years of sustained investment in research and development has left the Australian cotton industry well placed to manage nitrogen（N） fertiliser. The average production in the Australian cotton industry today is greater than two tonnes of lint per hectare due to improved plant genetics and crop management. However, this average yield is well below the yield that would be expected from the amount of N fertiliser used. It is clear from the recent studies that across all growing regions, conversion of fertiliser N into lint is not uniformly occurring at application rates greater than 200-240 kg·hm;of N. This indicates that factors other than N availability are limiting yield, and that the observed nitrogen fertiliser use efficiency（NFUE） values may be caused by subsoil constraints such as sodicity and compaction. There is a need to investigate the impact of subsoil constraints on yield and *** in NFUE will be made through improved N fertiliser application timing, better targeting the amount of fertiliser applied for the expected yield, and improved soil N management. There is also a need to improve the ability and confidence of growers to estimate the contribution of soil N mineralisation to the crop N budget. Many Australian studies including data that could theoretically be collated in a meta-analysis suggest relative NFUE values as a function of irrigation technique; however, with the extensive list of uncontrolled variables and few studies using non-furrow irrigation, this would be a poor substitute for a single field-based study directly measuring their efficacies. In irrigated cotton, a re-examination of optimal NFUE is due because of the availability of new varieties and the potential management and long-term soil resilience implications of the continued removal of mineralised soil N suggested by high NFUE values. NFUE critical limits still need to be derived for dryland systems.

关于人类和环境相互关系的传统观念正在迅速改变。那种认为人类与自然是相互隔离的,自然资源是取之不尽用之不竭的,而且认为世界是稳定的、可以预测的并且是平衡的旧观点已经过时了。在动态的社会-生态景观中强调学习和灵活性管理为基础的适应性方法的新的理念框架已经迅速初现端倪。我们以两个典型的世界遗产地区(大堡礁和大峡谷)为案例来研究如何在自然资源管理中通过改善科学和社会两个方面的结合来指导多尺度管理系统的变革从而应对和处理人类越来越占据主导的世界中出现的不确定性、风险和变化。
