Risk and safety analysis in long-term perspective   总被引:1,自引:0,他引:1  
Ylva Uggla 《Futures》2004,36(5):549-564
This paper analyses how the tension between safety demands and uncertainties in calculations and management is dealt with in discussions of mercury and radioactive waste disposal in Sweden. Mercury and radioactive waste management can be seen as extreme cases where modern notions of risk management and control are called into question. The hazards associated with these categories of waste entail a request for safe handling over an unusually long time span; at the same time, it is infeasible to fully predict the consequences of a chosen method of waste disposal. In safety analyses, uncertainties are dealt with with reference to margins, further research, dilution in time and space, the role of nature and by consideration of the risk and prolonged time perspective relative to other risks and even longer time spans. The suggested solutions to the waste problem are moulded and defined to correspond to the demands of long-term safety. However, even though the definition of the suggested solutions to the waste problem as safe is politically satisfactory at rhetorical level, it will not necessarily be successful when the waste disposal policies are put into practice.  相似文献

The paper explores developments in the choice of measurement method in financial reporting over the half century that has elapsed since the foundation of Abacus in 1965. The discussion is confined to the specific problem of measuring individual assets and liabilities, rather than the wider problems of the choice of measurement unit (as in inflation accounting) or capital maintenance (as in income measurement). Changes in financial reporting practice and standards are considered in relation to developments in academic research. This has been a two‐way process: research has been stimulated by problems of practice, and practice, particularly as embodied in standards, has been influenced by the results of research. Both have been influenced by significant events in the world economy, notably the inflation of the 1970s and the global financial crisis that started in 2007. Historical cost has retained its position as the predominant measurement technique in practice, but considerable progress has been made in the implementation and understanding of current value measurements, although the principles for choosing between alternative current values (particularly ‘entry’ values as opposed to ‘exit’ values) require further exploration by standard setters, assisted by academic research.  相似文献

The paper discusses the necessity for futures studies and argues the need for methods giving explicable understandings of future possibilities so that decisions and policies can be as future-proof as possible. A taxonomy for futures methodologies based on their passive, preventive or anticipatory characteristics is proposed. The anticipatory methodologies are further categorised into subjective and numerical approaches. The paper goes on to review some of the principal numerical approaches such as system dynamics and econometric methods. The subjective approaches, such as the extended scenario, Delphi and Field Anomaly Relaxation are considered and it is concluded that, in general, they, and especially Field Anomaly Relaxation, are the more fruitful line of attack on the futures problem. Some directions for further research are suggested.  相似文献

In disciplinary research progress is reached and assessed by referring to the state of research in a specific field. But what is progress in transdisciplinary research, where several disciplines and further societal actors may be involved? Based on the conception of transdisciplinary research as a collaboration of academic as well as non-academic thought-styles, and based on the understanding of transdisciplinary research as research that develops a comprehensive, multi-perspective, common-good oriented and useful approach to a socially relevant issue, the question of progress is discussed for four view-points: (a) the people concerned about the issue are much less interested in the question of progress in transdisciplinary research than in a better handling of the real world problem; (b) members of a disciplinary, business, governmental or civil society's thought-style, who gain a more comprehensive understanding of an issue through the transdisciplinary research process, are more interested in further elaborating the issue within their thought-style, than in general lessons on progress; (c) progress on the level of personal experience mainly means that members of academic or non-academic thought-styles realize that they are a member of a specific thought-style among others. Progress would be made by integrating this experience in general education and special training; (d) finally a lot of general lessons can be learned and elaborated as tools, cases studies and approaches form the perspective of a thought-style interested in how to understand and manage transdisciplinary research.  相似文献

Futures research is now an accepted part of the Soviet planning and control system. Soviet forecasting methods are similar to Western methods, differing chiefly in a greater insistence that complex methods are no substitute for a substantive understanding of the problem. Soviet methodological innovations are worth watching for, however. Actual forecasts are often not published, but the Soviet vision of the future is fairly clear. Key events will include the disappearance of capitalism and the achievement of controlled fusion. Despite its prominence, Soviet futures research has a somewhat uncertain future; further growth will depend both on its own achievements and on any realignment of official policy which may come with the inevitable leadership changes in the Kremlin.  相似文献

Groundwater vulnerability is a burning issue all over the world due to the deterioration of groundwater level and increasing contamination which poses serious detrimental risk to the environment. To identify this risk, extensive research has been carried out to assess the groundwater vulnerability by using different methods. Generally, the process-based method, statistical method, and overlay & index methods are used in this regard. DRASTIC method is one type of overlay & index method for vulnerability assessment. This paper represents a comprehensive review of available literature on the applications of Geographic Information System (GIS)-based DRASTIC method for groundwater vulnerability assessment. Also, some other types of overlay & index methods are compared with the DRASTIC method. This study discusses the rescaling of rating ranges and modification of DRASTIC parameters, and shows the comparison of DRASTIC method with other vulnerability assessment methods. In addition, this study identifies some research gaps on the present state of groundwater vulnerability assessment and proposes some research needs for further studies. The findings of this study indicate that the combination of GIS and DRASTIC are more viable for groundwater vulnerability assessment. Furthermore, modified DRASTIC method can be used for agricultural, arid, semi-arid, and basaltic regions.  相似文献

Robert Kaplan and David Norton introduced the Balanced Scorecard in their 1992 Harvard Business Review article. 2012 marks 20 years since that article. This anniversary has motivated me to review the state of research on the balanced scorecard, to highlight gaps in that research and to outline some ideas for further research. To this end, I reviewed 114 articles published in 25 accounting journals and 67 articles in business and management journals in the period 1992–2011. The findings of this literature review are presented in three parts. First, the reviewed articles are categorised by topics, research settings, theories, research method, and primary data analysis techniques. Second, the contributions of research to the field and the lessons learned from these studies are discussed. Third, knowledge gaps in existing balanced scorecard research are identified, leading to consideration of several ideas for future research. The last section offers my final remarks.  相似文献

An innovative cumulative distribution function (CDF)-based method is proposed for deriving optimal reinsurance contracts to maximize an insurer’s survival probability. The optimal reinsurance model is a non-concave constrained stochastic maximization problem, and the CDF-based method transforms it into a functional concave programming problem of determining an optimal CDF over a corresponding feasible set. Compared to the existing literature, our proposed CDF formulation provides a more transparent derivation of the optimal solutions, and more interestingly, it enables us to study a further complex model with an extra background risk and more sophisticated premium principle.  相似文献

Sustainability of complex societies   总被引:1,自引:0,他引:1  
Historical knowledge is fundamental to sustainable development. Recent research implicates the development of complexity in systems of problem solving as a primary cause of societal collapse. Diminishing returns to problem solving limited the ability of historical societies to resolve their challenges, and will limit the ability of contemporary societies to address global change. The solutions to this dilemma lie within
1. (a) knowledge of our historical position in a system of evolving complexity
2. (b) the further development of energy to finance problem solving.

改革开放以来,我国的公共管理学科得到了快速的发展,但是,该学科在短时间内发展之快,也暴露了很多问题。其中,公共管理学研究方法落后的问题非常突出。最突出的表现是公共管理学科没有自己独立的方法论体系。公共管理的学科方法论依然是以主流社会科学的方法论为主,这也造成了该学科过分依赖定量研究而忽视定性研究与价值判断,偏离了公共管理学科的特点和使命。我们认为,建立起能体现学科独立性的中国公共管理研究方法,对促进公共管理教育发展,提高公共管理科学应用研究水平具有非常重要的意义。  相似文献
