I am afraid there is clear evidence that acts of gross misconduct have taken place. This is a shameful thing for the United Nations to have to say, and I am absolutely outraged by it. —Kofi Annan, United Nations Secretary-General Despite promulgating a comprehensive set of guidelines to deter UN personnel from committing acts of sexual misconduct, allegations of sexual exploitation and abuse have become widespread within United Nations peacekeeping missions. The policy of zero-tolerance for peacekeeper misconduct has not been matched by strong disciplinary measures, and crimes are often ignored and rarely punished: absentee fathers, rapists and murderers simply disappear back in their home countries. In countries where women and children rarely have the same economic resources, political rights and authority or control over their environment—or their bodies—they easily become prey for those in perceived positions of power and authority. By failing to hold those responsible to account, the UN may in fact be fuelling even greater discrimination and violence against women and children. In order to ensure those who are mandated to protect to do not become perpetrators of abuse, the UN must take a stronger stand against those who commit acts of sexual misconduct, and must ensure that victims see that their abuser is brought to justice and that reparation is offered. A recent report submitted by the Secretary-General's Special Envoy on Sexual Exploitation and Sexual Abuse makes a comprehensive set of recommendations to prevent, detect, and respond to these allegations. The aim of this essay is to highlight some of the main points of the Special Envoy's report, and to examine the practical challenges the UN and troop/police contributing countries will face when attempting to implement these recommendations. 相似文献

针对机载双基地雷达下视环境下非均匀地杂波的抑制问题,首先论述了抑制双基地机载雷达非均匀杂波的内插变换类空时自适应处理(space time adaptive processing,STAP)方法。然后在此基础上,提出了一种改进的空时二维内插变换方法(improved space time interpolation transfor-mation,ImSTINT)。该方法将训练样本的杂波子空间映射到单基地地基雷达的杂波子空间中,减少了变换后杂波子空间的自由度。仿真表明该方法比传统的内插变换类方法的杂波抑制性能好,且具有较强的稳健性和较少的样本量需求。 相似文献

高架索的多体动力学模型 总被引:1,自引:0,他引:1
针对目前海上补给装备研制中尚无可用的高架索模型的现状,从多体动力学角度入手,研究了绳索多体系统动力学模型的建立方法,将绳索均匀划分为若干刚体单元,各单元之间采用球铰连接。用该方法建立了绳索的多刚体系统动力学模型,并在此基础上,应用仿真软件 ADAMS 对海上横向干货补给过程进行仿真计算。结果表明:海上补给高架索多刚体系统动力学模型完全可以模拟实际的高架索,且仿真计算结果与高架索力学振动模型的计算结果相比更贴近实际情况。 相似文献
