A network discourse has emerged during the last two decades, representing networks as self–organizing, collaborative, nonhierarchical, flexible, and topological. Progressive scholars initially embraced networks as an alternative to markets and hierarchies; neoliberal thinkers and policymakers have reinterpreted them in order to serve a neoliberal agenda of enhanced economic competitiveness, a leaner and more efficient state, and a more flexible governance. The European Commission and the German state have initiated and financially supported interurban network programs, broadly framed within this neoliberal network discourse, despite their long traditions of regulated capitalism. Really existing interurban networks depart, however, from these discourses. Embedded within pre–existing processes of uneven development and hierarchical state structures, and exhibiting internal power hierarchies, really existing networks are created, regulated, and evaluated by state institutions, and often exclude institutions and members of civil society, making them effective channels for disseminating a neoliberal agenda. At the same time, they create new political spaces for cities to challenge existing state structures and relations and are of unequal potential benefit to participating cities, both of which may catalyze resistance to neoliberalization. 相似文献

The palaeobiota from a middle to late Holocene succession in Tom Thumbs Lagoon, N.S.W., Australia, reflects a range of environmental conditions caused by sea-level changes and active estuarine sedimentation. At the base of the succession (~ ?0.4 m AHD) a thin bed, containing molluscs dated at 6.7 ka B.P. by radiocarbon and amino acid racemisation, and foraminifers is indicative of open estuarine conditions. From +0.35 m AHD towards the top of the sequence the charophyte Lamprothamnium succinctum occurs in subrecent deposits. This species is characterised here by statistical measurements, and new characters are described and illustrated. The charophytes record a drop in sea level and the establishment of a lower salinity artificial wetland. The investigation has also established that decalcification in charophytes can be related to acidification produced by the release of organic acids, aggravated after 1928 by anthropogenic pollution. 相似文献
