Design of accelerated life testing plans under multiple stresses

Accelerated life testing (ALT) using multiple stresses is commonly used in practice to resemble the operating stresses at normal operating conditions and obtain failure observations in a much shorter time. However, to date, there is little research into the theory of planning ALT for reliability estimation with multiple stresses. ALT with multiple stresses can result in a large number of stress‐level combinations which presents a challenge for implementation. In this article, we propose an approach for the design of ALT plans with multiple stresses and formulate multistress test plans based on different objectives and practical constraints. We develop a simulated annealing algorithm to efficiently determine the testing plan parameters. We demonstrate the proposed method with examples based on an actual test conducted using three stress types. The obtained optimal test plans are compared with those based on fractional factorial design. © 2013 Wiley Periodicals, Inc. Naval Research Logistics 60: 468–478, 2013     

Directional change‐point detection for process control with multivariate categorical data

Most modern processes involve multiple quality characteristics that are all measured on attribute levels, and their overall quality is determined by these characteristics simultaneously. The characteristic factors usually correlate with each other, making multivariate categorical control techniques a must. We study Phase I analysis of multivariate categorical processes (MCPs) to identify the presence of change‐points in the reference dataset. A directional change‐point detection method based on log‐linear models is proposed. The method exploits directional shift information and integrates MCPs into the unified framework of multivariate binomial and multivariate multinomial distributions. A diagnostic scheme for identifying the change‐point location and the shift direction is also suggested. Numerical simulations are conducted to demonstrate the detection effectiveness and the diagnostic accuracy.© 2013 Wiley Periodicals, Inc. Naval Research Logistics, 2013     

The revisionist historiography of Britain’s decolonisation conflicts and political science theses of civilian victimisation in counterinsurgency

ABSTRACT

Recent historical research exposed the myth of self-restraint as the distinctive feature of British counterinsurgency during decolonisation. This article shows that the revisionist historiography of British counterinsurgency has important, but unnoticed, implications for political scientists. Specifically, historical scholarship challenges the predictions and causal mechanisms of the main social scientific theses of civilian victimisation in counterinsurgency. Using revisionist historians’ works as a source of data, I test those theses against Britain’s decolonisation conflicts. I find that they do not pass the test convincingly. I conclude that political scientists should be more willing to explore the theoretical implications of new historical evidence on counterinsurgency campaigns.     

Military Spending and Economic Growth in the Middle East Countries: Bootstrap Panel Causality Test

This study revisits the causal relationship between military spending and economic growth in 10 Middle East countries via a panel causality analysis that accounts for cross-sectional dependence and heterogeneity across countries. Our results indicate unidirectional causality from military spending to growth for Turkey; one-way causality from economic growth to military spending for Egypt, Kuwait, Lebanon, and Syria; bidirectional causality for Israel; and no causality in either direction for Jordan, Oman, and Saudi Arabia. The empirical evidence does not provide consistent results regarding the causal relationship between defense expenditure and economic growth in these countries.     

MODELLING THE RELATIONSHIP BETWEEN DEFENSE SPENDING AND ECONOMIC GROWTH FOR THE FIJI ISLANDS

The goal of this paper is to examine the nexus between GDP and military expenditure. We model this relationship within a multivariate framework by including exports in the model. We use the recently developed bounds testing approach to cointegration and find that there is a long run relationship among the variables when GDP is the endogenous variable. Normalizing on GDP and using four different estimators, we find that in the long run both military expenditure and exports have a positive impact on GDP. Finally, using the Granger causality test, we find that there is evidence for military expenditure Granger causing exports and exports Granger causing GDP, implying that military expenditure indirectly Granger causes GDP in the short run. In the long run, we find that both military expenditure and exports Granger cause GDP for Fiji. Our findings are consistent with the Keynesian school of thought, leading us to derive some policy implications.     

The Long-run Causal Relationship Between Military Expenditure and Economic Growth in China: Revisited

This paper re-examines the long-run causal relationship between military expenditure and economic growth in China over the period 1952–2010. An empirical econometric analysis based on a Barro-style growth model is conducted. By employing the Bartlett corrected trace test, which provides better approximations of the finite sample distribution to determine the rank of cointegration, the results support the existence of a single long-run equilibrium relationship between the variables. Furthermore, it is confirmed that the cumulated shocks of military expenditure primarily originate from different components of shocks that relate to economic development rather than the other way round.
