Casualty Rates of US Military Personnel During the Wars in Iraq and Afghanistan

Abstract

In Operation Iraqi Freedom, which ended in August 2010, nearly 3500 hostile deaths occurred among US military personnel and 32,000 more were wounded in action (WIA). More than 1800 hostile deaths occurred during Operation Enduring Freedom (in and around Afghanistan) through 2014 and about 20,000 were WIA. A larger proportion of wounded personnel survived in Iraq and Afghanistan than during the Vietnam War, but the increased survival rates were not as high as some studies have asserted. The survival rates were 90.2% in Iraq and 91.6% in Afghanistan, compared with 86.5% in Vietnam. The casualty rates varied between the conflicts in Iraq and Afghanistan and before, during, and after the respective surges. Amputation rates are difficult to measure consistently, but I estimate that 2.6% of all WIA and 9.0% of medically evacuated WIA from the Iraq and Afghanistan theaters combined resulted in the major loss of a limb. Elevated non-hostile death rates (including deaths due to accidents, illnesses, homicides, or suicides) resulted in about 220 more deaths in Iraq and about 200 more deaths in Afghanistan than would have been expected in peacetime among populations of the size deployed to those two conflicts.     

科研工作的自组织过程及其政策启示

对工作对象的操控必须符合对象的性质或特点。从武警学院近三年的科研工作实践可以发现,要真正做好科研工作,使之进入良性循环,必须实现人为性与非人为性、有目的的组织性和科研系统自组织性的有机统一。这具有一般性的指导意义。

新疆高校新闻专业人才培养现状、问题与对策

作为区域内新闻专业人才培养的主要阵地,新疆高校在新闻专业人才培养上起步较晚。但随着新疆区域内新闻专业人才需求的逐步扩大以及国家政策的扶持,这种状况在上世纪八十年代后得以改观。上世纪九十年代末以来,新疆部分高校相继开办了新闻专业,使新闻专业人才培养阵地迅速扩张。短期内的迅速扩张,随之也带来了诸多问题。客观理性分析产生这些问题的原因并及时寻找解决问题的对策,对提高新疆高校新闻专业人才培养质量,为区域经济发展提供人才支撑有重要意义。

汉乐府名篇教学探析

乐府是汉代文学的重要部分,对五言诗歌的成熟起了极为重要的作用。在古代文学的教学过程中,将汉乐府和先秦时期的诗经、楚辞进行比较,从思想内容、叙事艺术、人物形象等方面解读汉乐府中的名篇,可以让学生更好地理解掌握汉代文学的特点。     

新疆高校毕业生留疆就业对新疆稳定和发展中的作用

改革开放二十多年来,新疆在各方面取得了长足的进步,但总体上还远远落后于东部发达地区,究其原因,人才匮乏是其中重要的影响性因素之一。地处西北边疆地区的新疆,要解决人才匮乏问题,除制定优惠政策引进内地高水平人才以外,还要鼓励新疆高校培养的内地毕业生留疆就业。新疆高校内地生源留疆就业,对新疆的稳定与发展都具有重要意义。

Analytic solution for the nucleolus of a three‐player cooperative game

The nucleolus solution for cooperative games in characteristic function form is usually computed numerically by solving a sequence of linear programing (LP) problems, or by solving a single, but very large‐scale, LP problem. This article proposes an algebraic method to compute the nucleolus solution analytically (i.e., in closed‐form) for a three‐player cooperative game in characteristic function form. We first consider cooperative games with empty core and derive a formula to compute the nucleolus solution. Next, we examine cooperative games with nonempty core and calculate the nucleolus solution analytically for five possible cases arising from the relationship among the value functions of different coalitions. © 2010 Wiley Periodicals, Inc.
