This article details two largely unreported atrocities by British forces operating against Arab rebels during the Arab revolt, 1936–9, at the Palestinian villages of al-Bassa and Halhul. It then examines the military-legal system that underpinned and authorised British military forces operating in aid of the civil power, suggesting that the law in place at the time allowed for a level of reprisals and punitive actions, such as happened at al-Bassa and Halhul. The article does not conclude that the law allowed for atrocities but it does argue that it gave a basic form and understanding to an operational method that was brutal and could lead to atrocities. It thus tests the idea in much of the literature on counterinsurgency that the British were restrained and used minimum force when compared to other colonial and neo-colonial powers fighting insurgents. 相似文献

In recent years a number of commentators have posited that the British reputation for conducting small wars has suffered in the wake of setbacks in Iraq and Afghanistan. The argument here contests whether such a tradition can be truly said to have ever existed. A close examination of this supposed tradition reveals it to be a myth. In fact, rarely have the British armed forces claimed a facility for counter-insurgency or small war. Invariably, commentators outside the Army have ascribed the tradition to them. Most notably, commentators in the United States keen to discern practices of minimum force or rapid institutional learning generated the narrative of British COIN expertise. Ultimately, what this myth reveals is that, when deconstructed, it is political will, not an ingrained understanding of fighting insurgencies, that has determined Britain's success, or otherwise, in so-called small wars. 相似文献

By running life tests at higher stress levels than normal operating conditions, accelerated life testing (ALT) quickly yields information on the lifetime distribution of a test unit. The lifetime at the design stress is then estimated through extrapolation using a regression model. In constant‐stress testing, a unit is tested at a fixed stress level until failure or the termination time point of test, whereas step‐stress testing allows the experimenter to gradually increase the stress levels at some prefixed time points during the test. In this work, the optimal k‐level constant‐stress and step‐stress ALTs are compared for the exponential failure data under complete sampling and Type‐I censoring. The objective is to quantify the advantage of using the step‐stress testing relative to the constant‐stress one. Assuming a log‐linear life–stress relationship with the cumulative exposure model for the effect of changing stress in step‐stress testing, the optimal design points are determined under C/D/A‐optimality criteria. The efficiency of step‐stress testing to constant‐stress one is then discussed in terms of the ratio of optimal objective functions based on the information matrix. © 2013 Wiley Periodicals, Inc.

Policies to counter the threat of weapons of mass destruction (WMD) have, for the most part, been modeled on strategies originally devised to counter the danger of nuclear proliferation. While useful in countering a traditional CBN (chemical/biological/nuclear)/WMD threat, current counter-proliferation and non-proliferation regimes are insufficient to meet the challenge of maritime terrorism. Maritime terrorism represents a new category of threat; one that partially overlaps with conventional WMD, but for which – due to the scope and nature of the maritime industry – traditional counter-proliferation policies may be inadequate and even inappropriate. This article outlines the means by which maritime shipping can be used as WMD and discusses the policies implemented to deal with these threats, in light of the challenges presented to traditional conceptualizations of WMD and counter-proliferation strategies. 相似文献

In this article we present a queueing-location problem where a location of a service station has to be determined. The two main results of this article are a convexity proof for general distances and a theorem that limits the area in the plane where the solution can lie. We also propose some solution procedures. 相似文献

The sword which is the subject of this article and which will be referred to as the Capel sword, is a fine example of what has become known as an Irish basket-hilt. Whilst there are other examples in existence, what makes this sword unique and particularly important is the fact that it is known to have been owned by two important Royalist military leaders, Lord Arthur Capel and Sir John Owen. These two extraordinary men came from different backgrounds but their fate was linked through circumstances beyond their control. The story this sword tells is one of comradeship, loyalty, total belief in a cause, betrayal and ultimate sacrifice. 相似文献
