中日安全生产监管体系的比较分析

近年来,虽然我国安全生产形势出现了好转,但安全生产形势仍然严峻,不容乐观。本文在对中、日两国安全生产形势进行分析的基础上,对比分析了中、日两国的安全生产监督管理体系,并归纳总结了日本安全生产监督管理体系的借鉴之处,指出了我国安全生产监督管理体系中存在的问题,以为我国安全生产监督管理体系的不断完善和健康发展提供借鉴。     

生产安全事故责任认定定量化方法的探讨

当前,我国生产安全事故的责任认定是在事故调查组分析调查事故原因后,对事故责任者承担的责任进行定性的责任认定,受一定的主观因素影响。为了避免主观因素的影响,本文提出了一种责任认定定量化方法,该方法首先从安全管理、安全技术和职业健康卫生三方面建立了完善的事故影响因素集;然后在分析事故原因后采用专家打分法(德尔菲法)确定各影响因素的影响度,并计算出与事故相关的责任者的累加影响度,即责任大小;最后根据事故造成的人员伤亡和经济损失情况对事故责任者作出处理。此方法对生产安全事故责任认定更加公正客观。

Assessment of eco-labelling criteria development from a strategic sustainability perspective

To turn current patterns of consumption and production in a sustainable direction, solid and understandable market information on the socio-ecological performance of products is needed. Eco-labelling programmes have an important role in this communication. The aim of this study is to investigate what gaps there may be in the current criteria development processes in relation to a strategic sustainability perspective and develop recommendations on how such presumptive gaps could be bridged. First a previously published generic framework for strategic sustainable development is described and applied for the assessment of two eco-labelling programmes. Data for the assessment is collected from literature and in semi-structured interviews and discussions with eco-labelling experts.The assessment revealed that the programmes lack both an operational definition of sustainability, and a statement of objectives to direct and drive the criteria development processes. Consequently they also lack guidelines for how product category criteria might gradually develop in any direction. The selected criteria mainly reflect the current reality based on a selection of negative impacts in ecosystems, but how this selection, or prioritization, is made is not clearly presented. Finally, there are no guidelines to ensure that the criteria developers represent a broad enough competence to embrace all essential sustainability aspects.In conclusion the results point at deficiencies in theory, process and practice of eco-labelling, which hampers cohesiveness, transparency and comprehension. And it hampers predictability, as producers get no support in foreseeing how coming revisions of criteria will develop. This represents a lost opportunity for strategic sustainable development. It is suggested that these problems could be avoided by informing the criteria development process by a framework for strategic sustainable development, based on backcasting from basic sustainability principles.
