动态灰色时序系统 DGTS 及其在安全策略规范中的应用

设计安全策略模型时应考虑安全策略的时序特性和灰色特性,还应综合考虑保密性、完整性和可用性三方面的需求。已有的安全模型没有描述时序性和灰色特性,而且一般只侧重描述保密性或完整性。为此,本文提出了动态灰色时序系统（简称ＤＧＴＳ）。本文详细描述了ＤＧＴＳ,以及基于ＤＧＴＳ的动态语义设计的灰色时序安全策略规范语言ＧＴＳＬ。     

Defence industries adjusting to change 1

This paper analyses the impact of terrorist activity on international tourist flows. To this end, we have estimated a cross‐sectional gravity equation for tourism from the G‐7 countries to a sample of 134 destinations over the period 2001–2003. Within this framework, we evaluate the deviation from ‘normal’ tourist flows due to terrorist activity, which is considered as negative advertising for the affected country. The analysis suggests that both domestic victims and international attacks are relevant factors when foreign tourists make their choice. This result is robust under alternative specifications. Moreover, the impact of terrorism is more severe in developing countries.     

TERRORIST THREATS AND TRANSITIONAL DYNAMICS IN AN OVERLAPPING GENERATIONS MODEL

Previous research has shown that the duration of a civil war is in part a function of how it ends: in government victory, rebel victory, or negotiated settlement. We present a model of how protagonists in a civil war choose to stop fighting. Hypotheses derived from this theory relate the duration of a civil war to its outcome as well as characteristics of the civil war and the civil war nation. Findings from a competing risk model reveal that the effects of predictors on duration vary according to whether the conflict ended in government victory, rebel victory, or negotiated settlement.     

Estimating defence budget saving from disarmament: the United States’ case

Probing the technology in the production of US national defence by using a dynamic cost‐function model with adjustment costs, this paper evaluates the effect of reducing the level of national defence on the defence budget saving. Our inquiry involves estimating the defence production structure without output data for non‐market goods that are normally unavailable. Our findings include: (i) the United States behaves rationally to minimize cost in the production of national defence; (ii) the adjustment costs are larger in disarmament than in military build‐up; (iii) due to the adjustment costs peculiar to disarmament, the defence budget saving from disarmament appears small, but cutbacks allow great savings on the defence budget.
