Think globally, act locally'? Climate change and public participation in Manchester and Frankfurt 总被引:1,自引:0,他引:1
'Think Globally, Act Locally' was one of the most famous slogans of the 1970s environmental movement. Discourses about global climate change are now a vivid illustration of this new 'global thinking'. Although there is a substantial amount of research about global environmental issues and policy initiatives, there is still a gap in understanding of how lay publics actually comprehend global climate change. Using qualitative research method, this study is a comparison of how lay publics in Frankfurt (Germany) and Manchester (UK) perceive these issues and the possible solutions. The study found strong similarities in lay public perceptions in both cities including that (1) awareness of global environmental issues is always contextualised in broader perspectives not exclusively 'environmental', (2) there is a shared and strong sense of global equity based on recognition of differences and (3) there is an ambivalence about the role of environmental 'information'. Differences between lay public perceptions in Manchester and Frankfurt can be explained by specific features of national cultures. 相似文献

The development of decentralized sources of power out of renewable sources of energies has been triggering far-reaching consequences for Distribution System Operators over the past decade in Europe. Our paper benchmarks across 23 European countries the impact of the development of renewables on the physical characteristics of power distribution networks and on their investments. It builds on a large spectrum of databases of quantitative indicators about the dynamics of installed capacity of renewable energy resources and the power generation out of them, electricity independence, quality of electricity distribution, smart grids investments, Network System Operators capital expenditures, length of the distribution networks, overall costs of power networks paid by private agents, and electricity losses, all in relation with the development of decentralized generation. The heterogeneity of these indicators across Europe appears to be wide notably because of physical constraints, historic legacies, or policy and regulatory choices. A cluster analysis allows for deriving six groups of countries that display statistically homogenous characteristics. Our results may provide decision makers and regulators with a tool helping them to concentrate on the main issues specific to their countries as compared to the European median, and to look for possible solutions in the experience of other clusters which are shown to perform better for some indicators. 相似文献

Ageing increases the income of a carbon tax ceteris paribus since energy consumption rises with age, as macro and micro data show. Ageing also increases some public expenditures, notably those of pay-as-you-go (PAYG) pension systems. Accordingly, there may be a case for recycling a carbon tax in an ageing context so as to finance ageing-related public expenditures. This article studies the interacting effects on intergenerational equity and growth of such a recycling. It relies on a general equilibrium model with overlapping generations parameterised with empirical data. Several results emerge. Implementing a carbon tax fully recycled through higher lump-sum pensions weighs relatively more on the intertemporal welfare of young and future generations. A carbon tax fully recycled through lower social contributions financing the PAYG bolsters the wellbeing of young and future generations but weighs on the welfare of baby-boomers and older cohorts. The redistributive effects of recycling a carbon tax can depend significantly on the way used to balance the PAYG regime. 相似文献

Evolution of bacterial community during bioremediation of PAHs in a coal tar contaminated soil 总被引:2,自引:0,他引:2
The monitoring of a windrow treatment applied to soil contaminated by mostly 2-, 3- and 4-ring PAHs produced by coal tar distillation was performed by following the evolution of both PAH concentration and the bacterial community. Total and PAH-degrading bacterial community structures were followed by 16S rRNA PCR-DGGE in parallel with quantification by bacterial counts and 16 PAH measurements. Six months of biological treatment led to a strong decrease in 2-, 3- and 4-ring PAH concentrations (98, 97 and 82% respectively). This result was associated with the activity of bacterial PAH-degraders belonging mainly to the Gamma-proteobacteria, in particular, the Enterobacteria and Pseudomonas genera, which were detected over the course of the treatment. This group was considered to be a good bioindicator to determine the potential PAH biodegradation of contaminated soil. Conversely, other species, like the Beta-proteobacteria, were detected after 3months, when 2-, 3- and 4-ring PAHs were almost completely degraded. Thus, presence of the Beta-proteobacteria group could be considered a good candidate indicator to estimate the endpoint of biotreatment of this type of PAH-contaminated soil. 相似文献

The ever-increasing complexity of disasters demands utilisation of knowledge that exists outside domains traditionally drawn upon in disaster management. To be operationally useful, such knowledge must he extracted, combined with information generated by the disaster itself, and transformed into actionable knowledge. The process, though, is hampered by existing, business-oriented approaches to knowledge management, by technical issues related to access to relevant, multi-domain information/knowledge, and by executive decision-making processes based predominantly on historical knowledge. Consequently, as shown by many recent incidents, the management of large-scale (mega) disasters is often inefficient and exceedingly costly. This paper demonstrates that the integration of modified information and knowledge management into the concepts of network-centric operations and network-enabled capabilities, and the employment of Boyd's OODA (Observe, Orient, Decide, and Act) Loop-based decision-making in unpredictable and dynamically changing environments, may address some of these problems. 相似文献

Biodegradable polymers are one of the most promising ways to replace non-degradable polymers. But, to be a real alternative to classical synthetic polymers and find applications, biopolymer (biodegradable polymer) properties have to be enhanced. Nano-biocomposites, which are obtained by incorporation of nanofillers into a biomatrix, are an interesting way to achieve these improvements. Modified and unmodified montmorillonites have been introduced into a biodegradable aromatic copolyester, poly(butylene adipate-co-terephthalate) (PBAT). Structural characterization, thermal and mechanical tests have been carried out to understand better the relations between the nanofillers structuring and the final nano-biocomposite properties. Main results show that clay incorporation and the obtained intercalated structures improve PBAT properties (enhanced thermal stability, increased stiffness) and thus may increase the attractiveness of this biopolymer. 相似文献
