The popular adage has it that ‘prevention is better than cure’. Given the heavy and enduring costs of armed conflicts, there is no disputing the fact that making efforts to prevent them from breaking out in the first place is better than waiting until it is too late. This entails two things: conflict prevention measures and early warning systems. Anything that could be done to effectively address the root causes of a conflict before it turns violent may fit into the former, while the latter aims to identify threats to these elements so that effective conflict prevention measures can be taken. In other words, ensuring ‘human security’ is the thrust of the former, while the latter serves as a surveillance camera for any deficit in providing the different components of this ‘human security’. It is with these two important issues that this essay deals, with particular reference to West Africa.     

What is Doctrine?

‘Doctrine’ has been part of military vernacular for at least a century. Nonetheless, it is a concept which is rather under-explored. The aim of this article is thus to break doctrine down into its component parts in order to grasp what a military doctrine actually is. Thereafter, the article points out different ways to utilise doctrine as a military devise. A doctrine cannot be, or rather should not be, all things to all men. On the contrary, doctrine can be a tool of command, tool of education or a tool of change. The main upshot of the article is that the future of doctrine is far brighter than its critics want us to believe.

Comparison between constant‐stress and step‐stress accelerated life tests under Time Constraint

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.

Rebels of the frontier: origins,organization, and recruitment of the Pakistani Taliban

The Pakistani Taliban, factionalized into some 40 groups, form a decentralized insurgent movement, often characterized by infighting, divergent motivations, and a shifting web of alliances. The Pakistani Taliban remain little understood because most scholars have avoided a serious treatment of the insurgent movement and instead focused on analyzing the geopolitics of the region and Pakistan's ‘double game’. This article seeks to fill this gap by dissecting the movement through selected theories of organization and mobilization. First, I explain the various dimensions of the conflict and the origins of the insurgency. Next, I discuss the Pakistani Taliban's political organization, categorizing it as composed of various warlord regimes. I further list the Taliban's component groups and numerical strength and chart the leadership structure. Lastly, I analyze insurgent recruitment strategies, accounting for the role of selective incentives, coercion, and genuine grievances.     

Responding to the failed state: The need for strategy

Given the challenges posed by failed and failing states, and the likelihood that such failure will continue well into the new millennium, the need for a strategic approach appears evident. Should we respond? If so, how and with what expectations? Answers to such questions require an underlying set of strategic guidelines. This article contributes to developing that strategy by examining common manifestations of state failure and some possible response objectives. It concludes by arguing that careful and tough analysis must guide our choices about where and when to respond, and how ambitiously we set our objectives.
