This article presents an asset‐level security risk management framework to assist stakeholders of critical assets with allocating limited budgets for enhancing their safety and security against terrorist attack. The proposed framework models the security system of an asset, considers various threat scenarios, and models the sequential decision framework of attackers during the attack. Its novel contributions are the introduction of the notion of partial neutralization of attackers by defenders, estimation of total loss from successful, partially successful, and unsuccessful actions of attackers at various stages of an attack, and inclusion of the effects of these losses on the choices made by terrorists at various stages of the attack. The application of the proposed method is demonstrated in an example dealing with security risk management of a U.S. commercial airport, in which a set of plausible threat scenarios and risk mitigation options are considered. It is found that a combination of providing blast‐resistant cargo containers and a video surveillance system on the airport perimeter fence is the best option based on minimum expected life‐cycle cost considering a 10‐year service period. 相似文献

聚焦物与装置范式是伯格曼将技术人工物还原到具体生活情境之后创造的一组对立概念。这种对立不仅体现在理论层面,而且还表现在现实生活中的自然信息、文化信息与技术信息之间的对立。通过剖析伯格曼有关聚焦物与装置范式关系的思想,有助于理清伯格曼经验的现象学技术哲学的研究进路。 相似文献

我国以社区矫正人员的居住地为矫正地。矫正地变更主要包括迁居型、暂离型、外出型三种类型。迁居型矫正地变更后,由新矫正地的社区矫正机构进行矫正;暂离型矫正地变更后,由现居住地矫正机构委托异地暂时居住地社区矫正机构进行矫正;外出型矫正地变更须由现矫正地社区矫正机构进行延伸矫正,并强化矫正措施。 相似文献

This article deals with the basic contradictions of risk management and responsibility regarding problem gambling and self-exclusions, and draws special attention to the role knowledge production and science play in the construction and evaluation of gambling risks. This remarkable case of corporate social responsibility (CSR) is analyzed from a risk-governance perspective. It is grounded on a case study of the CSR practice of the Dutch casino monopoly, in particular the problem gambling mitigation and self-exclusion program of this corporation. The intentions and operations of this ‘responsible gambling’ practice constitute new business values and working norms. At the same time empirical evaluations of the self-exclusion program reveal that despite all the efforts put in the risk-management strategies, a significant part of the problem cannot be addressed at all. This points toward a major paradox of risk management. Overall the article highlights the ambiguous nature of risk management and responsible gambling. 相似文献

Spatial Distribution of Flood Risk and Quality of Spatial Management: Case Study in Odra Valley,Poland 下载免费PDF全文
Dorota Rucinska 《Risk analysis》2015,35(2):241-251
This article presents methodological solutions aimed at presenting the spatial distribution of flood risk and quality of spatial management (land use), indicating both those areas used reasonably and those requiring modification. The purpose was to identify key risk areas and risk‐free areas from the point of view of human security and activity on the floodplains, based on the examples of the vicinities of Wroclaw and Raciborz in the Odra Valley, Poland. Due to recent climate change, Poland has suffered the effects of severe flooding (e.g., 1997, 2001, 2010). The analyses conducted were motivated by the European Parliament and Council's recently implemented Directive 2007/60/WE, as well as by the demand for studies for local spatial planning. The analysis indicates that reasonably developed areas do not account for the majority of those studied, making up 36% of the Wroclaw area and 15% of the Raciborz area. 相似文献

Risk‐Cost‐Benefit Analysis for Transportation Corridors with Interval Uncertainties of Heterogeneous Data 下载免费PDF全文
Access management, which systematically limits opportunities for egress and ingress of vehicles to highway lanes, is critical to protect trillions of dollars of current investment in transportation. This article addresses allocating resources for access management with incomplete and partially relevant data on crash rates, travel speeds, and other factors. While access management can be effective to avoid crashes, reduce travel times, and increase route capacities, the literature suggests a need for performance metrics to guide investments in resource allocation across large corridor networks and several time horizons. In this article, we describe a quantitative decision model to support an access management program via risk‐cost‐benefit analysis under data uncertainties from diverse sources of data and expertise. The approach quantifies potential benefits, including safety improvement and travel time savings, and costs of access management through functional relationships of input parameters including crash rates, corridor access point densities, and traffic volumes. Parameter uncertainties, which vary across locales and experts, are addressed via numerical interval analyses. This approach is demonstrated at several geographic scales across 7,000 kilometers of highways in a geographic region and several subregions. The demonstration prioritizes route segments that would benefit from risk management, including (i) additional data or elicitation, (ii) right‐of‐way purchases, (iii) restriction or closing of access points, (iv) new alignments, (v) developer proffers, and (vi) etc. The approach ought to be of wide interest to analysts, planners, policymakers, and stakeholders who rely on heterogeneous data and expertise for risk management. 相似文献

Six multi‐decade‐long members of SRA reflect on the 1983 Red Book in order to examine the evolving relationship between risk assessment and risk management; the diffusion of risk assessment practice to risk areas such as homeland security and transportation; the quality of chemical risk databases; challenges from other groups to elements at the core of risk assessment practice; and our collective efforts to communicate risk assessment to a diverse set of critical groups that do not understand risk, risk assessment, or many other risk‐related issues. The authors reflect on the 10 recommendations in the Red Book and present several pressing challenges for risk assessment practitioners. 相似文献

政府向社会力量购买服务不仅是推动政府职能转变的重要着力点,而且是扶持社会力量发展的重要措施。各地在推动这项改革过程中取得了很大成效,但也存在着制度设计不严密、制度衔接不顺畅等问题和障碍。将这项改革深入推进下去,需要坚持有层次地放开政府资源,加强对整个购买过程的动态管理以及建立政府购买公共服务改革同其他改革之间的联动机制等多项措施的推动。 相似文献

The stand-up comedy landscape has been transformed in recent years with an increased number of disabled comedians performing. Using semi-structured interviews with disabled comedians, this article provides a thematic analysis of the material and ideological motives, intentions and lived experiences of disabled comedians. Two themes are discussed: comedy management and control; and affirming disability through comedy. These themes are characterised by complexity and contradictions. The article concludes that, although not a straightforward process, stand-up comedy enacted by disabled comedians is potentially a powerful tool through which hegemonic norms around disability can be challenged and renegotiated. 相似文献
