Why do great powers fear oil coercion, and what explains the strategies they adopt to protect themselves from it? The paper identifies three types of anticipatory strategies great powers pursue: self-sufficiency, indirect control, and direct control. A state's choice of strategy depends on its degree of vulnerability to oil coercion, which in turn is determined by two independent variables: the amount of oil the country possesses compared to what it needs to meet strategic objectives and the susceptibility of its imports to physical disruption. Great powers fear oil coercion not only because they worry about damage to their economies; petroleum denial also threatens a country's military capabilities. Four case studies illustrate the theory, including Great Britain's efforts to reduce coercive vulnerability at the close of the First World War and Adolf Hitler's attempts across three periods to safeguard German oil access before and during World War II. 相似文献

This article explores the application of key informant research to examine barriers and facilitators to maternal health services in rural and pastoralist Ethiopia. The key informants were health extension workers (HEWs) who assist women with birth preparedness and facilitate timely referral to health centres for birth. While women encounter many barriers to giving birth in health facilities, where HEWs are supported by their communities and health centre staff, they can effectively encourage women to travel to health centres to give birth with skilled birth attendants rather than at home with unskilled relatives or traditional birth attendants. 相似文献
