国旗

在地震灾区采访,给我特别深刻印记的是那一面面红旗.那一面面飘扬的五星红旗:在救灾现场,在断垣残壁之上,在大企业,在小摊点,在路边,在学校,在医院,在街道,在田间地头,在成片的灾民安置点,在孤独的帐篷旁,在车站码头,在志愿者行列里,在各色人等手中……那大大小小、各种姿态、鲜红鲜红、迎风招展的,是中华人民共和国国旗。5月19日14时28分,天安门广场上,其他所有地方,庄严的国旗降下,汽笛、喇叭、警报鸣响,国人低头默哀。一刹那,仿佛     

农三师组建前后

根治叶河,征服沙漠,建设三线,繁荣南疆。一个规模宏大进军荒原的会战拉开帷幕早在20世纪60年代初,农垦部部长王震在开发塔里木誓师大会上就指出,开发塔里木,农一师在阿克苏,农二师在库尔勒,将来在喀什再成立个农三师。1965年10月,在喀什组建农三师的时机已经成熟,经中央西北局批准,自治区党委决定在喀什组建农三师。

干部,干字当头

实干兴邦,是习近平总书记对全体党员干部提出的工作要求。干部的工作业绩,应该是踏踏实实干出来的,不是跑来的,也不是要来的,更不是宣传出来的。一切问题,在干中解决;一切方法,在干中探索;一切机遇,在干中抓住;一切成绩,在干中取得。我们是人民军队的干部,工作必须想在前、冲在前、干在前。     

卧底,在最危险的地方

正这是一场战争,没有硝烟弥漫、子弹横飞,却险相环生、生死争锋。这里是战场,金三角近在咫尺,毒品渗入内地的"黄金通道"。他们,是一群特殊的军人和警察,在各个角落里出没,直面阴暗和危险,目标只有一个:肃清毒品。他们,有的卧底在最危险的缉毒前沿,有的身着橄榄绿,与毒贩周旋。在这里,没有人可以置身事外,在这里,每一刻都在战斗,战斗,一直并依然在继续——他们在家里,是温和的长者,隔壁家三岁的小儿子都可以"欺负"他,揪着他的头发骑大马。走出家门,他就是一匹狼,在面对每一个"猎物"时,冷静、沉着、果敢、迅捷,一击必中。     

边关雄鹰

在边关,无论是在晨曦还是在暮霭,鹰的展翅就像一面黑色的旗帜.这旗帜是静止的,也是动态的,在守防官兵心里不仅代表一个高度,更是梦想希望的天堂. 当然,在这里,鹰动静之间的风向,永远都是充满诗意和美感的—— 你瞧,在广阔的蓝天里,一只鹰的敏锐就像潜伏在大山隐蔽处的守防官兵,洞察着千里防线,挺举着万里江山.而在刚劲的翅膀上,处处呈现高傲和矫健. 在边防待久了,守防的官兵最喜欢读鹰的桀骜不驯,他们了解鹰都胜过了解自己.在这里,每一个守防的官兵都知道:鹰是最具灵性的精灵,在它们的心里,翱翔蓝天就是最美好的梦想.只要一息尚存,拨云穿雾都是毕生的追求.     

“信号盲区”捕捉到的“爱情信号”

在延绵起伏的内蒙古千里边界线上,手机信号大都在"盲区"。有战士这样说,长江的水再长,也流不过蓝色的蒙古高原;移动的信号再好,也移动不过遥远的边界线。人在天边,情在心底。在内蒙古边防服役,官兵们在非边防勤务,训练教育时,干部骨干或哨长还是允许用手机的。然而,远在天边,想用手机搜索点信号有时比登天还难,这可苦了这些年

Scheduling policies for an antiterrorist surveillance system

This article concerns scheduling policies in a surveillance system aimed at detecting a terrorist attack in time. Terrorist suspects arriving at a public area are subject to continuous monitoring, while a surveillance team takes their biometric signatures and compares them with records stored in a terrorist database. Because the surveillance team can screen only one terrorist suspect at a time, the team faces a dynamic scheduling problem among the suspects. We build a model consisting of an M/G/1 queue with two types of customers—red and white—to study this problem. Both types of customers are impatient but the reneging time distributions are different. The server only receives a reward by serving a red customer and can use the time a customer has spent in the queue to deduce its likely type. In a few special cases, a simple service rule—such as first‐come‐first‐serve—is optimal. We explain why the problem is in general difficult and we develop a heuristic policy motivated by the fact that terrorist attacks tend to be rare events. © 2009 Wiley Periodicals, Inc.

What Goes Up Must Come Down: Military Expenditure and Civil Wars

Abstract

This paper examines the impact of civil war on military expenditure. We employ two measures of military expenditure: the share of military expenditure in general government expenditure and the logarithm of military expenditures. We would reasonably expect a priori that military expenditure as a share of general government expenditure increases during a civil war and that such increases would taper off over the duration of a civil war. We also explore whether the termination of a civil war induces a decline in the share of military expenditure as a share of the general government expenditure in the short-run. We find evidence the of share of military expenditure increases during a civil war and falls in the year succeeding the end of a civil war, and, in particular, if a war ends in a peace treaty. The level of military expenditures, however, rises during civil wars and does not appear to decline in the short-term after the end of a civil war.     

The Canary in the Nuclear Submarine: Assessing the Nonproliferation Risk of the Naval Nuclear Propulsion Loophole

ABSTRACT

The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) allows states to exempt nuclear material from international safeguards for use in nuclear submarine programs. This material, however, could be diverted for nuclear weapons purposes without the knowledge of inspectors, creating a potentially dangerous loophole in the treaty. This article argues that exercising that loophole today would amount to admitting a nuclear weapon program, making it a particularly poor pathway to a weapon for a potential proliferant. Still, if states like Brazil ultimately exempt nuclear material from safeguards for a nuclear submarine effort, they could set a dangerous precedent that makes it easier for others to use the loophole as a route to a nuclear weapon capability. There are several policy options available to mitigate the damage of such a precedent; most promising is the prospect of a voluntary safeguards arrangement that would allow international inspectors to keep an eye on nuclear material even after it has been dedicated to a naval nuclear propulsion program.

Strategic dynamic sourcing from competing suppliers with transferable capacity investment

We study the supplier relationship choice for a buyer that invests in transferable capacity operated by a supplier. With a long‐term relationship, the buyer commits to source from a supplier over a long period of time. With a short‐term relationship, the buyer leaves open the option of switching to a new supplier in the future. The buyer has incomplete information about a supplies efficiency, and thus uses auctions to select suppliers and determine the contracts. In addition, the buyer faces uncertain demand for the product. A long‐term relationship may be beneficial for the buyer because it motivates more aggressive bidding at the beginning, resulting a lower initial price. A short‐term relationship may be advantageous because it allows switching, with capacity transfer at some cost, to a more efficient supplier in the future. We find that there exists a critical level of the switching cost above which a long‐term relationship is better for the buyer than a short‐term relationship. In addition, this critical switching cost decreases with demand uncertainty, implying a long‐term relationship is more favorable for a buyer facing volatile demand. Finally, we find that in a long‐term relationship, capacity can be either higher or lower than in a short‐term relationship. © 2009 Wiley Periodicals, Inc. Naval Research Logistics 2009

The 1983 Nuclear Crisis – Lessons for Deterrence Theory and Practice

This article distills insights for the scholarship of deterrence by examining the 1983 nuclear crisis – the moment of maximum danger of the late Cold War. Important contributions notwithstanding, our understanding of this episode still has caveats, and a significant pool of theoretical lessons for strategic studies remain to be learned. Utilizing newly available sources, this article suggests an alternative interpretation of Soviet and US conduct. It argues that the then US deterrence strategy almost produced Soviet nuclear overreaction by nearly turning a NATO exercise into a prelude to a preventive Soviet attack. Building on historical findings, this article offers insights about a mechanism for deterrence effectiveness evaluation, recommends establishing a structure responsible for this endeavor, and introduces a new theoretical term to the strategic studies lexicon – a ‘culminating point of deterrence’.
