Migrating to the Post-Oil Era, over 10000's km2 of Powerscapes - the solar-collecting infrastructure - will be gradually constructed across the arid desert, for the indispensable production of solar energy to sustain Middle East's economy and global energy supply. The contingency of introducing the Powerscapes is a spatial problem. Unlike a powerplant that burns coal or oil, the scale of the Powerscapes is dramatically extensive. The inserted Powerscapes will interiorize the desert landscape and shelter the ground from the harsh direct sunlight that will be captured for power supply. Transformation in biological development, meteorological activity and geological phenomena will be inevitable, but the change that reduces the heat and evaporation rate will make its climatatic dynamics more habitable for human, animals and plants - an invaluable opportunity for the synthesis of energy production and climate conditioning. This thesis investigates the strategic programming and spatial configuration of such constructed landscape, capitalized by its new temporal characteristics, and sensitively adapting to it. Layers of material will be organized to form "Strata" of temporal conditions to be stretched across the landscape. To forge a symbiotic relationship between Solar Collection, human habitation, agricultural production and wild nature, the layers of material will delineate, push, flip, intersect, puncuate, wrap and merge, responding to programmatic needs and geographical dynamics that the natural geology and the Powerscapes together create. Such adaptive organization also permits certain geometrical and configuration logic to reiterate themselves in multiple scales, formulating a fractalic field with recursive part to whole relationships.by Chun Lun Otto Ng.M.Arch

Decentralization and democracy in Eastern Europe: a sceptical approach

The author focuses on the link between local government decentralizatio and democracy in Eastern Europe. It is shown that decentralization is a multidimensional concept and that actual local government systems can be positioned differently on each dimension (functions, control, and finance) depending on the implicit model of local government. Formal and substantive definitions of democracy are distinguished and some conventional measures examined; it is concluded that decentralization and democracy do not necessarily go together. The degree of decentralization and implicit models of postsocialist local government in Eastern Europe are then outlined, with a focus on the contrast between Budapest and Moscow. The development of social movements in the two capitals is taken as an index of substantive democracy and is shown to be influenced not only by�the extent of decentralization but also by other features of the local political context. This illustrates the earlier argument that the relation between decentralization and democracy is an empirically variable one rather than a necessary one.

Towards a Strategic Approach to Housing Behaviour: A Study of Young People's Housing Strategies in South-East England

A model is advanced of young people's housing behaviour as resulting from strategies regarding household type, child-bearing, work, expenditure and family help, which in turn are partly a response to housing constraints. The model is applied to a sample of 724 young people in South-East England and it is shown that between 3 per cent and 34 per cent of young people had adopted particular strategies in the previous year in response to housing constraints. Strategic behaviour was not limited to any single social category, but the first four types of strategy were more likely among households with manual or part-time workers; younger, unmarried people were more likely to put up with awkward household arrangements; and older, married people and owner-occupiers were more likely to adopt expenditure-related strategies and to defer having children. This approach rejects the view that housing decisions are made by pre-existing households with given characteristics. Rather, household structure and resource levels result from strategies, and housing decisions involve trade-offs between aspirations and the acceptance of sacrifice and dependency - features which are ignored by measures of 'ability to pay' such as affordability
