民航安全风险定量评价模型研究

在对民航风险评价的现状和常用的定量风险评价方法进行分析的基础上,建立民航安全风险定量评价模型。在计算风险的可能性时,不仅考虑了风险的历史发生概率,而且利用风险发生概率影响因素所发生的变化对风险的历史发生概率进行修正,从而得出在当前情况下风险的发生概率,并且首次提出指数型权重的概念;在计算风险的后果时,考虑风险的直接损失和间接损失,并通过计算多种可能后果的期望的形式,综合考虑多种可能的后果情况;通过上述的可能性和严重性从而达到对安全风险进行定量评价的目的。最后,给出了一个算例,其结果表明该模型具有很强的实用性。

Conjoint analysis for environmental evaluation

BACKGROUND, AIM AND SCOPE: Conjoint analysis and the related choice-modelling methods have been used for many years in marketing research to evaluate consumer behaviour and preferences for different kinds of product attributes. Recently, the number of applications in environmental science and management has started to grow. Conjoint analysis is found in many different forms, and the environmental studies evaluated in this review display the same range of methods as in other fields. The key characteristic of all these methods is that trade-offs are evaluated by jointly considering a number of important attributes. MAIN FEATURES: This paper is a review of the literature on environmental applications of conjoint analysis and assesses in which environmental area conjoint analysis has been most successful. The method and the design of the studies are reviewed as well. RESULTS: A total of 84 studies were found, dealing with environmental issues that were evaluated by conjoint analysis. The studies concern agriculture, ecosystem management, energy, environmental evaluation, forestry, land management, pollution, products, recreation, environmental risk analysis and waste management. DISCUSSION: Choice experiments seem to have a comparatively stronger position in environmental studies than elsewhere. Most of the environmental applications are related to natural resource management. This is somewhat surprising, but a number of reports have appeared also on product evaluation, which could be a key application area in the future. CONCLUSIONS: Compared to marketing and transportation, the number of environmental conjoint studies is rather small but increasing, and the method has proven to work effectively in eliciting preferences on environmental issues. In environmental issues, experimenters often use choice experiments, especially concerning ecosystem management and environmental evaluations. When it comes to evaluating preferences concerning agriculture, forestry, energy and products, a more traditional approach of conjoint analysis is favoured. RECOMMENDATIONS AND PERSPECTIVES: Two new areas of application are identified in this review--environmental communication and expert elicitation. Conjoint analysis can thus be developed into a useful instrument for environmental risk analysis and communication, both of which are necessary for an efficient approach to risk governance.

Disaster reduction,loss and damage data,and the post-2015 international policy agenda

Disaster risk management, particularly management of climate-related risks, has become central to the international policy agenda. Reducing hazard-related loss and damage relies heavily on scientific inputs. Science, in turn, relies on data—in this case 1) risk-related data on hazards, exposure and vulnerability, and 2) data on associated loss and damage outcomes. The latter, data on losses and damage, are also post-2015 international policy outcome indicators at the highest level, required for countries’ monitoring of progress in reducing disaster risk, adapting to climate change, and achieving sustainable development. Although the quantity and accessibility of loss and damage data are improving, a number of issues continue to constrain their potential. These include needs for more consistent cataloguing of hazards and extreme events, more systematic and accurate documentation of per-event losses and damage, more precise cross-referencing of hazard events with associated loss and damage, and improved standardization and interoperability among databases. We identify measures for improvement in this regard, both for research purposes and for post-2015 international policy implementation.     

Making water policy work in the United Kingdom: A case study of practical approaches to strengthening complex,multi-tiered systems of water governance

We propose a suite of actions for strengthening water governance in contexts with complex, multi-tiered arrangements. In doing so, we focus on the collective water policies and approaches of the United Kingdom (UK), including those of devolved governments, which confront a host of serious water-related challenges—from massive flooding of urban areas and agricultural lands, to pressure on aquifers from rising water demand and drought. Further complexity in addressing these challenges has emerged in the wake of the June 2016 vote to leave the European Union (EU), so-called ‘Brexit’, and the ensuing ‘separation process’ with uncertainties for institutional and governance arrangements to follow. We make ten proposals for improving and reinvigorating water policy in complex, multi-layered situations, and comment specifically on their application in the UK setting. These are: put in place a system-wide water policy; fully embrace community-led nested river basin planning and management; fully fund river basin planning and management; re-focus the policy framing; use best-available data and information; create conversational spaces and become a more water-literate society; mobilise people; support and sustain core community networks; underpin river basin plans with regulatory provisions and effective monitoring and enforcement; and address systemic institutional amnesia. Individually and collectively, we contend that these actions will have a marked effect on transforming the planning and management of water resources. A system-wide water policy that maintains and builds on the substantive biophysical and socio-economic benefits delivered through implementation of the EU Water Framework Directive, together with the more recent Floods Directive, will galvanise stewardship of water in the UK. We urge more active engagement with and empowerment of the multiplicity of system ‘actors’, and highlight the role of non-government actors in a post-Brexit world as conduits for reaching out to and connecting directly with a wide range of water-related actors, especially across the EU. While attention to-date has focused on a plethora of specifically water-related projects, initiatives, plans and regulations, what is really needed is a systemic, long-term view of water resource management.
