试论全球化背景下的非传统安全

非传统安全是近几年频频出现的热点问题。它是在全球化背景下显现的,尤以2001年的“9·11”事件和2003年的非典型肺炎(SARS)为其典型代表。非传统安全越来越受到各国政府和学者们的重视,但它却系不同于过去我们所认识的传统安全,在形成机理、内涵、特点及与其他安全观之间的关系至今还没有得到共识,处于理论的不成熟阶段。因此,文章就以上几点进行了初步的论述。     

重要信息系统的灾难恢复刍议

现代社会和生活越来越依赖于IT系统,信息系统遭到灾难和毁灭性打击将是社会公众的灾难和噩梦。美国“9.11”事件中纽约交易所成功实施了信息服务灾难恢复计划,使得全球对于“业务连续和灾难恢复”有了重新的认识。在我国,信息安全也日益成为政府部门管理层、企业和公众关注的重要话题。企业的弹性、系统的健壮性,信息系统的抗毁性与灾难恢复日益深入人心,风险管理越来越为业界所重视。地震部门在政府应急联动系统中具有重要作用,其本身的信息系统安全已逐步引起重视。     

Combating piracy and armed robbery in Asia: The ReCAAP Information Sharing Centre (ISC)

The Regional Cooperation Agreement on Combating Piracy and Armed Robbery Against Ships in Asia (ReCAAP) Information Sharing Centre (ISC) is an international organisation that comprises 14 member countries in the region. Despite its many advantages, the ISC has some weaknesses, which when addressed could bring regional cooperation to a new level and which could make the ISC a model for other regions.

National and transnational borderlanders’ attitudes towards the security fence between Israel and the Palestinian Authority

The subject of the security fence between Israel and the Palestinians in the West Bank has become a major issue in Israel and in the world in the last several years. The main aim of this research is to reveal the attitudes and thoughts about the fence held by local residents living in settlements (borderlanders) in the proximity of a part of the security fence that has already been completed. The research concentrates on the western-Israeli side of the fence, as it aspires to delve into and understand the meaning and implications of the security fence on matters such as personal security, safety of property and freedom of movement, the possibility of maintaining social and economic ties between the two sides and feelings about living in the area in the future. Underlying this research is the transformation occurring in the border area as a result of its closure by construction of the security fence, after many years in which it was open partially. This process has many diverse consequences, some of them contradictory, on the two populations residing near the border in Israel: the majority Jewish population (the national borderlanders), and the minority Arab population (the transnational borderlanders).

Data,interface, security: Assembling technologies that govern the future

Over the last decade, fire governance practices in the British Fire and Rescue Service (FRS) have undergone fundamental transformation. Rather than just being responded to as and when they occur, the FRS have adopted a range of anticipatory governing strategies to govern fires in anticipation of their occurence. This turn towards anticipatory governance has been facilitated in no small part by the digital infrastructure now embedded in the FRS. Composed of data, hardware, software, fibre-optic cables along with human analysts and organisational processes, this infrastructure operates to make risk projections on fire which shape and condition strategic decision making. This paper explores the operation of this digital infrastructure through the notion of interface. Drawing on empirical material relating to processes of data sourcing and risk calculation, interfaces account for the sites, moments and experiences in which human and non-human agents relate to one another in making fire risk projections. Showing relations to exist spatially, temporally and sensually, I argue that interfaces are crucial to the operation of an anticipatory security apparatus which relies on digital devices.     

Alternative climate policy pathways in the US

Although it is likely that the political–economic coalition required for implementing a federal cap-and-trade programme for GHGs in the US is now sufficiently strong, the structural impediments that have prevented its legislative passage remain impressively durable and can be expected to continue to lay waste to congressional proposals for the foreseeable future. Indeed, given the complex history of environmental policy gridlock in Washington since the early 1980s, any expectations that a cap-and-trade programme could have been realistically achieved through the traditional legislative passage in Congress are fundamentally misplaced. Building on previous research, it is argued that – as with most other forms of environmental policy in the US over the past three decades – a national carbon market is more plausible given alternative policy pathways, which if taken are capable of circumventing the Federal Congress altogether. In particular, the interaction between litigation against the federal government and the ‘rulemaking’ authority possessed by the Executive Branch provides the potential space for the current administration to unilaterally establish a model rule for a national carbon-trading programme.

Policy relevance

This article aims to contribute to American climate policy debates by re-thinking the policy mechanisms most capable of establishing a national carbon market in the US. By taking into account the array of structural factors that have prevented the legislative passage of such a programme in federal Congress, a range of alternative policy ‘pathways’ is considered that have historically allowed progressive environmental policies to endure in Washington (despite increased Congressional gridlock over the past few decades). Two specific alternative strategies and the relationship between them are assessed: the use of litigation to impose legal obligations on federal agencies to regulate effluents, and the use of executive authority to define the nature and scope of environmental regulation. The administration's current potential to unilaterally develop a model-rule for a cap-and-trade programme under the Clean Air Act is emphasized, and the political implications of such a strategy are considered.
