This paper models and estimates Greek defence spending over the 1950–1989 period. It employs the Stone‐Geary welfare function and estimates levels of defence expenditures by the Engle‐Granger two‐step procedure. The Dickey‐Fuller test regression for cointegration is specified in terms of the significance of additional augmentations. The Deaton‐Muellbauer functional form is then employed and an estimating equation for the expenditure share of defence is derived. This specification is compared with the levels equation through a number of non‐nested tests involving model transformation. 相似文献

This paper examines whether non-lethal weapons (NLWs) enhance the capability of the US armed forces to conduct irregular warfare (IW) operations. With expectations that the operational environment will only continue to become more complex in the future, NLWs may reduce the level of violence received, as well as dispensed, by US forces while performing tasks in the IW spectrum. We argue that NLWs increase the ability of US forces to address the long tail of warfare and their deployment should be increased in the near term. 相似文献

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 相似文献

One of the most important issues facing the post‐Cold War U.S. defense establishment concerns the future allocation of combat tasks and responsibilities among different branches of the armed forces. The challenge is to reduce unnecessary redundancy across roles and missions when resources are highly constrained, without compromising military effectiveness. Defining the policy problem as one of resource allocation rather than operational effectiveness, we develop a methodology for allocating roles and missions. Our methodology focuses at the highest level of force aggregation and uses a mathematical programming model to produce cross‐service cross‐mission trade‐offs that will yield the best total force combat and non‐combat potential within resource consumption constraints. 相似文献

The Sixth Review Conference of the Biological Weapons Convention (BWC) gave the future of biological disarmament new hope. It brought the BWC back closer to the core of multilateral efforts to combat the weaponization of disease, agreed to an intersessional work program for 2007–2010, created an implementation support unit, and revived the interrupted process of BWC evolution through extended understandings agreed at review conferences. However, its aims were deliberately modest. Having set their sights realistically low, delegations did not have to lower them much further. What was most important was to prevent U.S.-Iranian acrimony from paralyzing the conference. With deadlock once again narrowly averted, the conference had to clear away the debris left from past dissensions in order to open the way to constructive evolution for the treaty. In particular the conference avoided contentious subjects such as permanent organization and verification measures for the BWC; its institutional deficit and compliance problems remain. Successes and limitations of the conference are analyzed, as is its equivocal outcome on confidence-building measures. Developing on the endogenous principle, the BWC will continue to need constant attention. At the center of a complex edifice, the BWC must be kept sound, strong, and solid. 相似文献
