图书馆用户服务的创新转型

网络信息技术的发展,给图书馆带来了巨大变革。图书馆为顺应时代发展积极采取各种措施,实现了组织方式、工作方式和服务方式等多方面的改革与创新。但是,如何从“信息用户”和“信息服务”方面进行组织、开发、交流和提供的状态,使用户以多种方式获取信息、处理信息,还面临许多问题。从图书馆用户需求的变化和图书馆服务模式变革等方面看,通过不断推出新的工作方式和服务形式,可以催生出新兴图书馆业态,促进图书馆多元化趋势的快速发展。     

新加坡中小学公民教育的特点及其启示

中国和新加坡同属亚洲儒家文化圈,有着相近的文化传统,都面临着经济全球化条件下东西方文化的融合与碰撞。而在西方文化的冲击下,新加坡政府坚持技术上依赖西方,精神上固守东方,因此新加坡中小学公民教育开展地卓有成效,使全体国民的道德素质明显提高。文章从四个方面分析了新加坡中小学公民教育的特点,他们在公民教育方面的成功经验,值得我们学习和借鉴。     

African nations as proxies in covert cyber operations

The growth of the African Internet, and services related to the Internet, has been rapid over the last decade. Following this market expansion, a variety of service providers have started to provide access. A fast-growing market puts pressure on the providers to deliver services first and only then seek to secure the networks. Over time, industrialised nations have become more able to detect and trace cyber attacks against their networks. These tracking features are constantly developing and the precision in determining the origin of an attack is increasing. A state-sponsored cyber attacker, such as intelligence agencies and electronic warfare units, will seek to avoid detection, especially when the attacks are politically sensitive intelligence-gathering and intrusion forays into foreign states' networks. One way for the attacker to create a path that links the attacks and the originating country is by actions through a proxy. The less technologically mature developing nations offer an opportunity for cyber aggression due to their lower level of security under the quick expansion of the Internet-based market. Developing countries could be used as proxies, without their knowledge and consent, through the unauthorised usage of these countries' information systems in an attempt to attack a third country by a state-sponsored offensive cyber operation. If the purpose of the cyber attack is to destabilise a targeted society and the attack succeeds, the used proxies are likely to face consequences in their relations with foreign countries, even if the proxy was unaware of the covert activity.

Warning of Terror: Explaining the Failure of Intelligence Against Terrorism

Many scholars and analysts have studied intelligence failure and surprise and developed theories to explain disasters such as the attack on Pearl Harbor. Others, especially since the 9/11 attacks, have examined the rising threat of terrorism and see it as posing a particularly difficult challenge for the intelligence community. But little work has been done to integrate the earlier literature on intelligence failure with the newer threat of terrorist attack. This article attempts such an integration, by examining the bombing of the US Marine Barracks in Beirut in 1983; it concludes that most studies of the Beirut bombing are mistaken in their assessment of the role played by intelligence in that disaster, and suggests that our understanding of intelligence failure against surprise attacks needs to be revised in the age of terrorism.
