Some basic principles for philosophical definition work are introduced and then applied to safety and related concepts. Definitions are provided first for comparative safety concepts such as “safer than” and then for the monadic “safe”. It is shown that “safe” is an inherently inconsistent concept, i.e. it cannot be restored to consistency without giving up what we perceive as some of its central elements. The reason for this is that both absolute and relative conceptions of safety are entrenched in common usage of the term. In order to avoid the inconsistency a strategy of terminological ramification is proposed: We should distinguish between the two concepts “reasonably safe” and “absolutely safe”. Any usage of “safe” or “safety” simpliciter should be seen as an abbreviated reference to one of these two closely related, remarkably confusable, but still unmergable concepts. 相似文献

Identifying Determinants of Nations' Wetland Management Programs Using Structural Equation Modeling: An Exploratory Analysis 总被引:1,自引:0,他引:1

Integrated management and policy models suggest that solutions to environmental issues may be linked to the socioeconomic
and political characteristics of a nation. In this study, we empirically explore these suggestions by applying them to the
wetland management activities of nations. Structural equation modeling was used to evaluate a model of national wetland management
effort and one of national wetland protection. Using five predictor variables of social capital, economic capital, environmental
and political characteristics, and land-use pressure, the multivariate models were able to explain 60% of the variation in
nations' wetland protection efforts based on data from 90 nations, as defined by level of participation in the international
wetland convention. Social capital had the largest direct effect on wetland protection efforts, suggesting that increased
social development may eventually lead to better wetland protection. In contrast, increasing economic development had a negative
linear relationship with wetland protection efforts, suggesting the need for explicit wetland protection programs as nations
continue to focus on economic development. Government, environmental characteristics, and land-use pressure also had a positive
direct effect on wetland protection, and mediated the effect of social capital on wetland protection. Explicit wetland protection
policies, combined with a focus on social development, would lead to better wetland protection at the national level. 相似文献

The purpose of this paper is to analyse under what conditions, with respect to CO2 emission-reduction and biofuels-for-transport targets, the trading in the EU of CO2 credits and solid and/or liquid biofuels is cost-effective from the perspective of an optimisation energy systems model. We use the PEEP model covering the EU27 (except Bulgaria, Malta, and Cyprus) to generate insights about the cost-effectiveness of different options under different policy scenarios. Trade in CO2 credits is a cost-effective option, in all relevant policy scenarios. Trade in some biofuels (mainly from central and eastern European countries to the EU15) is cost-effective in all assessed scenarios. In the case of CO2 targets (whether national or at the EU level) there is trade in solid biofuels. When biofuels-for-transport targets are also implemented, trading both solid and liquid biofuels is cost-effective. 相似文献

By inherent safety is meant that a hazard is eliminated rather than being managed by various add-on equipment and procedures. Practices of inherent safety have been developed in the chemical industry, and include for instance the substitution of hazardous substances by less hazardous ones. Inherently safer design strives to eliminate the possibility of major adverse events even when the probabilities of these events are small or cannot be meaningfully estimated. Considerations of security can be more easily incorporated into this approach than into most other branches of risk and safety analysis. Therefore, inherent safety has a great potential as a meeting-ground for the much-needed coordination of safety and security work. Its philosophical underpinnings are outlined, and proposals are made for more efficient promotion of its principles. 相似文献
