This paper addresses the relationship between accumulated knowledge and U.S. policy dealing with failed states and terrorism. The central thesis is threefold: (1) that more was known about the possible linkages between failing states and terrorism than appears in pre-9/11 U.S. policies; (2) that since 9/11 some important realignment of knowledge and practice has occurred, but it remains partial and incomplete; and (3) that new knowledge, especially about the policies to sustain and promote legitimate governance, needs to be generated in order to support an effective grand strategy for addressing the threats and challenges of the twenty-first century. The paper recommends such a grand strategy and, in addition to the required new knowledge, a significant reorganization of the U.S. national security policy-making apparatus. International studies curricula appear well suited for contributing to that new knowledge and the practitioners we require.  相似文献

Divorce, although a statistical norm, is a developmental trauma to the children involved. This article looks at the two-camp emotional environment of a divorcing family and its effect on the formation of a child's identity. By examining developmental ages, chosen according to divorce research, the author attempts to show how the interspouse emotional cathexes negatively affect a child's sense of self in ways specific to the child's age at the divorce.  相似文献

From a conflict resolution perspective, it is clear why the child support guidelines are not going to reduce the adequacy and compliance gaps in child support payment conflicts between parents. As it stands, the conflict over equally sharing child support is destructive rather than positive. The guidelines do not reframe the conflict for the parents, enabling them to believe the interests of children are more important than their own interests to win the child support battle. To transform conflict from destructive to positive, the elements of conflict–expression of the conflict, scarce resources and rewards, and interdependency–must be transformed. It is argued that the guidelines do not transform the conflict but facilitate it. Courts and attorneys are also significant players in the child support conflict.  相似文献

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning.  相似文献

Archibald T. Strong, born in Melbourne, was the son of an Australian scholar who went to an academic post at Liverpool. The younger Strong received his secondary and tertiary education in England. There, he became proficient in modern European languages and literature. He initially planned a career in the law, but for health reasons returned to Australia to the Department of English at the University of Melbourne. Prior to the First World War, Strong became prominent in Melbourne literary circles and also a prolific commentator on world affairs. As an early member of the Round Table group in Australia, Strong assessed Imperial Germany as posing an existential threat to the British Empire and hence to Australia's security. The nation's future, he believed, lay in unwavering defence of the Empire. Strong evinced a distinct impatience with fellow citizens, especially on the socialist left, who failed, in his view, to understand the realities of Australia's position in the world and what was at stake in the Great War.  相似文献
