郭洞：钱塘上游的静谧山村

浙江,所谓东南形胜,风雅钱塘,大抵指的是下游一带,那如昆曲般的绮丽华美,直可从《武林旧事》、《陶庵梦忆》一类的笔记中慢慢找寻;而“奇山异水,天下独绝”的中游地区,则像是性灵的诗词,最宜在杂花生树的暮春三月浅斟低唱;唯有上游一带,因地处偏远,支流纵横,山川复杂,犹如众多飘逸的传奇,细说不尽。单说婺江上游,有一武阳川,夹岸多山,不高不低,众山间有一小平原,说是平原,其实也不过是稍为平整的丘陵而已,稻米、茶叶、桑蚕、金针、苎麻、灰鹅,     

Arms control for armed uninhabited vehicles: an ethical issue

Arming uninhabited vehicles (UVs) is an increasing trend. Widespread deployment can bring dangers for arms-control agreements and international humanitarian law (IHL). Armed UVs can destabilise the situation between potential opponents. Smaller systems can be used for terrorism. Using a systematic definition existing international regulation of armed UVs in the fields of arms control, export control and transparency measures is reviewed; these partly include armed UVs, but leave large gaps. For preventive arms control a general prohibition of armed UVs would be best. If that is unattainable, several measures should be taken. An explicit prohibition of autonomous attack, that is without a human decision, should be added to IHL. Concerning armed UVs remotely controlled by a human soldier, recommendations differ according to type or mission. New kinds of uninhabited nuclear-weapon carriers should be banned. Space weapons should be prohibited in general. UVs smaller than 0.2–0.5 m should be banned. Bigger remotely controlled armed UVs not equipped with weapons of mass destruction should be subject to numerical limitations in various categories. For these the Treaty on Conventional Armed Forces in Europe is an important precedent.
