The European community's recognition of new states in Yugoslavia: The strategic implications

The EC's recognition of new states in former Yugoslavia is considered by most analysts to have seriously aggravated the conflict in the region. This article challenges the conventional wisdom and argues that the strategic effects of recognition have been largely overstated. The prospect of recognition played no significant role in the Slovene determination to sustain their campaign for independence and therefore bears little responsibility for the first phase of the war. In Croatia, recognition ‐ together with the deployment of UN peacekeepers ‐ may even have had a mitigating effect. Only in Bosnia is there any correlation between recognition and an intensification of hostilities but it is doubtful whether non‐recognition would have prevented the eruption of violence since Bosnian Serb aspirations for an ethnically homogeneous state entity could not be realised without resort to war. The real relevance of recognition lies with the opportunities for more effective international action which it created. It was the failure to seize these opportunities, rather than the strategic effects of recognition, which better explains the tragic events that ensued.

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.

Command and Control of India's Nuclear Forces

The Indian government has not made a public comment about the status of its nuclear weapon program since approving a nuclear doctrine in 2003. However, there is now enough information in the public domain to determine that the command-and-control system for the nuclear program has steadily matured in accordance with the intent of the approved nuclear doctrine. The Indian government has successfully mitigated many of the issues that plague the conventional military. The result is a basic command-and-control system that is focused only on the delivery, if ordered by the prime minister, of nuclear weapons. The system is not as robust as those of the United States and Russia, but is in place and ready as new Indian nuclear weapons enter into operation. The command-and-control system is developing to meet India's needs and political compulsions, but not necessarily as part of a more assertive nuclear policy.     

A lagrangean relaxation algorithm for the constrained matrix problem

We present variants of a convergent Lagrangean relaxation algorithm for minimizing a strictly convex separable quadratic function over a transportation polytope. The algorithm alternately solves two “subproblems,” each of which has an objective function that is defined by using Lagrange multipliers derived from the other. Motivated by the natural separation of the subproblems into independent and very easily solved “subsubproblems,” the algorithm can be interpreted as the cyclic coordinate ascent method applied to the dual problem. We exhibit our computational results for different implementations of the algorithm applied to a set of large constrained matrix problems.
