The Hydrogen Bomb,Lewis L. Strauss and the Writing of Nuclear History

In January 1950 President Harry S. Truman announced that the United States would proceed with further work to determine the feasibility of a ‘Super’, or hydrogen, bomb. The events leading up to that decision – counter-pressures and advocacy from a number of quarters, including the divided Atomic Energy Commission (AEC), the nuclear scientists, Congress and the Pentagon – is well known. Less attention has been given to how the story of the Super came to be told in official and popular publications. Admiral Lewis L. Strauss, rogue member of the AEC, later presidential adviser on atomic affairs and AEC chairman, was one of the most vigorous advocates of developing thermonuclear weapons. He was also a highly skilled player of bureaucratic politics. This article draws upon the Strauss archives to examine how he used his position and his contacts to shape the history of the H-bomb to his own political advantage.     

A multiple‐shift workforce scheduling model under annualized hours

Many manufacturing and service organizations in Europe have used annualized hours, also known as flexiyear, to successfully tackle seasonal demand. Under annualized hours, the employer has a certain number of labor hours available in a year and the employer can allocate the hours over the year according to manpower need. A problem in planning for annualized hours is the scheduling of the workforce over the year. We present an algorithm to generate an annual schedule for a scenario in which a facility operates one or more shifts and manpower need may vary from week to week. © 1999 John Wiley & Sons, Inc.

Allocation of carrier-based attack aircraft using non-linear programming

The paper presents the formulation and several solutions of a model for allocating a fixed number of aircraft to carriers and to missions. The amount of damage that can be inflicted is maximized. A nonseparable concave nonlinear objective function expresses diminishing marginal damage. Linear constraints on aireraft, carrier space, and aircraft availability for missions are included. The model is solved using the sequential unconstrained minimization technique (SUMT). The model is presented in terms of a scenario. Several different exponential damage functions are treated, and S-shaped damage functions are discussed.     

Bayesian enhanced decision making for deteriorating repairable systems with preventive maintenance

Since a system and its components usually deteriorate with age, preventive maintenance (PM) is often performed to restore or keep the function of a system in a good state. Furthermore, PM is capable of improving the health condition of the system and thus prolongs its effective age. There has been a vast amount of research to find optimal PM policies for deteriorating repairable systems. However, such decisions involve numerous uncertainties and the analyses are typically difficult to perform because of the scarcity of data. It is therefore important to make use of all information in an efficient way. In this article, a Bayesian decision model is developed to determine the optimal number of PM actions for systems which are maintained according to a periodic PM policy. A non‐homogeneous Poisson process with a power law failure intensity is used to describe the deteriorating behavior of the repairable system. It is assumed that the status of the system after a PM is somewhere between as good as new for a perfect repair and as good as old for a minimal repair, and for failures between two preventive maintenances, the system undergoes minimal repairs. Finally, a numerical example is given and the results of the proposed approach are discussed after performing sensitivity analysis. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2008     

Does Military Spending Really Matter for Economic Growth in China and G7 Countries: The Roles of Dependency and Heterogeneity

This study revisits the causal linkages between military spending and economic growth in China and G7 countries (i.e. Canada, France, Germany, Italy, Japan, the UK, and the USA) by focusing country-specific analysis for the period 1988–2010. The panel causality analysis, which accounts for both cross-country dependency and heterogeneity across countries, is employed in this study. Our results find evidence of the neutrality hypothesis for Italy, France, and Germany, the military spending–growth detriment hypothesis for both Canada and the UK, and one-way Granger causality running from economic growth to military spending for China. Furthermore, we find a feedback between military spending and economic growth in both Japan and the USA. Thus, our results do not support that one size fits all.     

The Royal Navy's Polaris lobby, 1955–62

This article examines the background to the Royal Navy's acquisition of Polaris. The conventional wisdom is that the Navy had little interest in Polaris, which was foisted on it upon the cancellation of Skybolt. Extensive use of files in the Public Record Office is made to mount the contrary argument, that the Admiralty had been interested in the submarine-launched ballistic missile since at least 1955, that there was widespread support for it among the Naval Staff, that a substantial amount of preparatory work was undertaken with the assistance of the US Navy, and that the naval staff were prepared to accept the deterrent role. Naval tactics – to play a waiting game and feign indifference – have contributed to the establishment of the orthodox interpretation, as has the view that the Navy was handicapped by the lack of a body of doctrine within which the deterrent role could be accommodated. The article shows that the orthodox account cannot be sustained by the evidence, which points to a naval triumph in terms of Whitehall politics and inter-service competition.
