EXPORT CONTROLS AND INTERNATIONAL SAFEGUARDS

Export controls and international safeguards are central to ensuring international confidence in the peaceful uses of nuclear materials and technologies and to achieving adequate oversight on the transfer and use of nuclear materials, technology, and equipment required for the development of proliferation-sensitive parts of the nuclear fuel cycle. Although the independent strengths of export controls and international safeguards rely largely on universal adherence, there may be opportunities to exploit the shared strengths of these systems. This article provides background information on the separate evolution of export controls and international safeguards, considers how these two elements of the nonproliferation regime interact, and identifies some possible avenues that could, over time, lead to wholly integrated activities.     

An Analysis of the Threat of Malicious Chemical Use by Nonstate Actors: Questioning the State-based Approach to Chemical Nonproliferation

ABSTRACT

This study seeks to evaluate the threat of malicious chemical use by non-state actors. It finds that non-state actors have primarily turned to ready-to-use crude chemical weapons (CW) instead of traditional CW agents. Interestingly, the worst crude CW attacks have been more destructive than those employing traditional CW. Scenarios for catastrophic consequences exist, but chemical attacks have typically been used to accomplish tactical goals, which leverage psychological and economic impacts. Therefore, successful efforts to counter CW proliferation by non-state actors must be substantially different from those targeting states.

Review of the ordered and proportionate flow shop scheduling research

Ordered flow shop models have appeared in the literature since the mid‐1970s and proportionate flow shop models have appeared since the early 1980s. We provide a detailed review of these models along with some analysis and potential topics for future research. © 2012 Wiley Periodicals, Inc. Naval Research Logistics, 2013     

Counter‐punching on the Mudzi: D Company, 1st Rhodesian African Rifles,on operation ‘Mardon’ 1 November 1976

Designed to harrass and weaken Ian Smith's principal enemy, Robert Mugabe, in his safe haven of Mozambique, Operation ‘Mardon’ involved co‐ordinated incursions over the Rhodesian border on a wide front. The secondary purpose was to persuade the African nationalist insurgents to abandon their incursion routes in the north‐east and south‐east in favour of those from the east where the mountainous terrain favoured their interception. Although other Rhodesian units wreaked more physical damage, D Company, 1st Battalion, the Rhodesian African Rifles, inflicted the heaviest casualties in their classic infantry attack on Mudzi Camp.¹     

Meeting the China challenge: Some insights from scenario‐based planning

‘Meeting the China Challenge’ employs the methodology of scenario‐based planning to offer a set of recommendations for long‐term U.S. policy toward China. The article first describes the core elements of this analytical technique. It then uses a version of the scenario‐based planning approach to establish four plausible scenarios regarding China's future role in East Asian security. Finally, it outlines a combination of shaping and hedging strategies that would best advance US security interests in East Asia over the next 20 years.
