核心学术资源(CAR)项目作为教图公司推出的一项知识型服务,旨在打造一套科学、有效的图书评价体系,并协助用户制定相应的馆藏建设方案。CAR项目调查和分析12所世界一流大学的藏书数据,以收藏学校的数量确定书目的核心级,核心级越高,代表书目的馆藏价值越高。选取核心级在三级以上,即三校以上共藏的图书作为核心书目(CAT)。Food price volatility is one of the major challenges facing current and future global food systems. Since 2006, global food prices have fluctuated greatly around an increasing trend and price spikes were observed for key food commodities such as rice, wheat, and maize. The full or partial transmission of these global food price changes to individual developing countries, together with domestic food price changes, caused by domestic factors such as extreme weather events and market disruptions, caused governments to respond in a variety of ways. While there is ample description of the nature, content, and causes of food price fluctuations during the last 5 to 7 years, very little is known about the processes that led to policy responses or the relative power and behaviour of the participating stakeholder groups.
