当代人类生存危机的哲学思考 总被引:2,自引:0,他引:2
人类从来没有经历过无危机的时期。本文从哲学的角度分析了当代人类面临的生存危机的新特点-多重性和全球性、相关性和渗透性、严峻性和紧迫性;指出当代人类正面临着三大危机:自然危机、社会危机和人类自身的危机;并认为当代人类生存危机的产生具有一定必然性,其主要根源是人类实践活动的双重效应。 相似文献

Particularly in view of the general trend for governments to withdraw from environmental regulation and leave the field to market processes, and in view of the growing importance of (transnational) environmental NGOs, the question arises whether and to what extent the local level as a location for production activities of whatever kind may influence the environmental performance of industrial enterprises. The concept proposed for the local level in this study incorporates the business-cluster and the (creative) milieu approach. The study uses disputes about the pulp industry in Germany in the period between 1950 and 2005 as an example to investigate the influence of local actors and local knowledge. It appears that the perception of industry-related environmental problems, as well as the solutions proposed, increase in quality as the volume of localised industry-specific knowledge expands. At the same time, responses at the local level are unmistakeably informed by debates about environmental problems on the national plane as well as by discussions about development paths at the local and/or regional level. 相似文献

Within the environmental social sciences, theories of practices are used by an increasing number of authors to analyze the greening of consumption in the new, global order of reflexive modernity. The use of practices as key methodological units for research and governance is suggested as a way to avoid the pitfalls of the individualist and systemic paradigms that dominated the field of sustainable consumption studies for some decades. With the help of practice theory, environmental governance can be renewed in three particular ways: First, the role and responsibilities (not) to be assigned to individual citizen-consumers in environmental change can be specified. Secondly, objects, technologies and infrastructures can be recognized for their crucial contribution to climate governance without lapsing into technological determinism. Third, the cultural framing of sustainability can be enriched by looking into the forms of excitement generated in shared practices of sustainable consumption. We conclude by discussing the need to investigate the globalization of practices from a post-national perspective in both science and policy. 相似文献

Some resource-based economies become wealthy while others stay poor and Norway belongs to the first category. This paper argues that part of the answer to why Norway has managed to benefit from its rich natural resources is found in the formation of a well-functioning national innovation system. The paper integrates the innovation system approach with a historical approach through the concept of co-evolution. The empirical study investigates how innovation systems evolve in natural resource industries through analysing the co-evolution between industry, knowledge organisations and national policy in the Norwegian aluminium and petroleum sectors. Parallels are found in the development of these two sectors, which are: (i) the deliberate use of concession laws to seize value creation and technological development from foreign direct investments, (ii) the establishment and prioritisation of state-owned companies and (iii) the more or less intentional formation of a national innovation system. The paper points to the relevance of analysing the historical evolution of national innovation systems to understand the creation of their specific path-dependent characteristics, to analyse how policy influences the creation and working of innovation systems, to use a multilevel approach in studies of innovation systems and to consider how innovation processes in different industries are linked in value chains and through knowledge flows. 相似文献

Knowledge generation and the interactions that allow for knowledge exchange are key processes of innovation. Yet these processes are not well understood at the farm level, nor are they well reflected in policy approaches for agricultural innovation. Farmers in New South Wales have used diverse ways to implement innovations in land management. They employ a range of strategies including observing signals from the landscape, independent testing and trialling, use of agronomists, participation in farmer groups and in farmer-driven research programmes. Steps to foster farmer-driven innovations and knowledge-intensive agricultural systems require greater subtlety to enable flexibility, the incorporation of contemporary scientific knowledge and support for sustainable initiatives. More research on innovation and on policy engagement is required to foster on-farm innovative capacity. 相似文献
