This paper makes the case for advancing sustainability science partnerships (SSPs) both within universities and through innovative means of integrating universities with external public‐private and civil sectors. It links the basic principles of sustainable development with an emerging science of cooperative learning that connects researchers to a wide range of partners. SSPs are specifically designed to be transformational through becoming active agents for societal change. Universities play a special role here because they can act both as communication networks and as laboratories for developing the capability to design and manage SSPs in the creative transition to sustainability. It is gratifying to note that these ideas are beginning to emerge in a number of universities, with European examples being highlighted in this paper. Further steps towards introducing full‐blooded SSPs across the university spectrum are suggested.  相似文献

In recent years urban entrepreneurialism has become a metropolitan strategy to cope with the challenges of an increasingly flexible global economy. Building on a debate about the problematic nature of this strategy we argue that cooperation of cities, or metropolitan cooperation, constitutes a new policy option for local actors which has the potential to overcome the negative effects of urban competition. In order to explore this potential we analyse the fundamental changes of the local state and existing cooperative efforts. This analysis shows that so far metropolitan cooperation is mainly experimental in character and a policy option that moves forward by trial and error and by learning from success and failure. We see this as partly due to a lack of an adequate theoretical framework dealing with the economics of urban systems. By way of synthesizing different academic discourses we suggest a conceptualization of metropolitan cooperation which takes into account the potential economic benefits and institutional requirements of cooperative behaviour of urban actors. Based on these considerations we establish criteria for suitable thematic fields of metropolitan cooperation and suggest forms of institutionalization.  相似文献

Research on the decomposition of bone collagen offers the key to a wealth of hidden information, for instance, to understanding palaeoclimatic conditions; habitat-specific parameters such as altitude; and for the reconstruction of palaeodiet and subsistence patterns. Radiocarbon dating, one of the most commonly used geochronological techniques is also preferentially carried out on bone collagen. Because negatively charged ions, and especially phosphate groups, are responsible for the tight bonding between organic molecules and bone, soluble serum proteins need not necessarily be leached from buried bone. The authors' hypothesis is that intruding minerals, aided by recrystallization of the bone mineral matrix, and colloid formation, aided by humic substances, form protective layers that preserve serum proteins in bone even after long periods of burial. We have used electrophoresis and Western blotting to recover protein fractions from about 150 archaeological bones from various sites and epochs (up to 5500 BC ) and have succeeded in recovering, purifying all, and identifying some of the proteins. Molecular weight bands corresponding to albumin, transferrin and a-2HS-glycoprotein (A2HS) were frequently recovered. This paper presents the method for separating serum proteins from archaeological bone and for their identification. Twenty-five per cent of samples with the respective molecular weight band still gave a positive immunological reaction with antibodies. We conclude that non-collagenous proteins, especially serum proteins, may be well preserved in bone.  相似文献
