Taphonomy of marine environments has been studied mostly from individual cases. The formation of adipocere, or "grave-wax," is an important indicator of the postmortem interval. In the present paper, the conditions and the timing of adipoceric formation are observed in a series of 15 cadavers recovered at different times, over a period of 433 days, from the same contained environment. Initial foci of adipocere on the subcutaneous tissue of the cadavers were detected as early as 38 days from the time of immersion in cold (10-12 degrees C) sea water. The discrepancies between our findings and previous reports on the correlation between time since death and decomposition stages in marine environments are discussed. 相似文献

Despite the CIA's improved analytical tradecraft and increased resources, the future of its analytic mission remains in doubt. Post-9/11 improvements have been coupled with a continued focus on current intelligence priorities that minimize attention to the development of strategic research and deeper knowledge. Simply increasing the number of analysts has not produced deeper expertise. The CIA's traditional recruitment and training methods, as well as its rewards and promotion system, encourage analysts to avoid concentrating on any single area of regional or functional expertise in favor of moving around the agency to build a successful career. A continued reliance on risk-avoidance security practices also restricts analysts' contact with non-government and foreign experts who often have needed political and cultural knowledge of intelligence topics. To rectify these inadequacies, the CIA's analytic directorate needs to develop incentives for analysts who wish to develop more strategic analysis and remove the security barriers to closer collaboration with experts outside the US government. Developing cross-agency analytic collaboration would also maximize expertise and would benefit from intelligence community-wide training programs similar to what the US military does at its senior service colleges. 相似文献
