空间信息栅格体系与服务聚合技术

空间信息应用中存在的数据海量、分布异构、处理复杂、计算密集等问题制约了空间数据和信息的广泛共享和应用。空间信息栅格(SIG)以Grid和WebServices技术为核心,共享并汇集地理上分布的海量空间信息资源,实现动态整合与集成。在构建开放性SIG七层应用体系的基础上,重点研究SIG服务聚合技术,基于Petri网和图论提出了一种新的服务聚合流程模型(服务/资源网),同时构建了可扩展的服务动态选择模型(SISM),实现服务聚合过程中的动态服务选择。结合国家地质调查业务应用,通过地下水资源评价应用实例对SIG的实用性和有效性进行了验证。     

关于增强各民族国家认同的几点思考

当今是民族个性张扬的时代,极端民族主义、恐怖主义和民族分裂主义是其外在表现形式,这是一种异化的民族认同,不利于各民族国家内部各民族对该国的国家认同和国家安全。应该以公民权为本位来构建民族认同,进而形成整体的国家认同;以保障公民生存权平等为契机,构建现实意义上的国家认同;以维护各民族人民的根本利益为核心,化民族主义为爱国主义;以保证各民族的和睦发展为目标,整体提高国家构建新时期和谐社会的能力。     

CIVIL SOCIETY AND VIOLENCE—HOW TO MANAGE IN THE TOWNSHIPS WITHOUT THE ARMY

This article discusses the validity of national security threats in Botswana and whether they justified the creation of the Directorate of Intelligence and Security Services (DISS), which has been controversial since its formation. Since its inception in 2008, the DISS has been accused of many human rights violations and politicisation. Without fully deliberating on the basis for its creation, some discourses have focused on the politicised operations without relation to what the DISS is supposed to be doing. The author works under the assumption that debates should be shaped by whether it was necessary to create the DISS, and, if so, how we can shape and steer debates on its oversight, management, reform and operations. This article argues that despite the politicisation of the DISS, Botswana's national security threats are both real and imagined; and that domestic threats to national security have moved from the conceptual ‘imagined’ category to the ‘real’. However, that in itself did not warrant the design and mandate of the DISS, and the article argues that it was external threats that really warranted the creation of a civilian intelligence agency. The article concludes that Botswana faces a plethora of external security threats – traditional and non-traditional – that warranted the creation and continuance of the DISS.

Offset Contracts as an Insurance Device in Building the National Security

A dynamic multi-stage decision-theoretic approach is introduced to establish the optimal offset and its incidence, the contract price arising from bargaining, and the scale of the acquisition. A new rationale is suggested for offsets in terms of their role as an insurance devise. Results are derived for the pricing of delivery contracts subject to offset claims and their national security implications. It is shown that the national security is strictly convex in the offset transaction. As to the incidence of the offset, the offset claim is shown to be capitalised in the delivery price. The bargaining price is shown to depend on the value of the product to be delivered for the national security, the relative negotiation power of the contracting partners and the social cost of public funds. The analysis highlights the expectation effects of offsets on the bargaining price and the scale of delivery. The results aid in explaining why offsets are widely used in procurement contracts for defence materiel. As they contribute to the national security, they should be allowed to survive and not be denied under competition laws.
