Implementing transit oriented development in Greater London

This book provides new dimensions and a contemporary focus on sustainable transport, urban regeneration and development in eight countries spanning four continents at different stages of development. It examines the role of transit oriented development (TOD) in improving urban sustainability and providing different transport choices, exploring how these can be implemented in modern cities. Establishing a new agenda for TOD, experts in the field critically evaluate the links between urban transport investment and economic, social and environmental sustainability, introducing new methods of analysis. The chapters investigate the international dimensions of TOD, providing crucial insights into issues such as uneven development, transport emissions, global warming, car dependence and the challenge of powering vehicles with sustainable fuels. Urban and regional planning, transport studies and environmental management scholars seeking to understand urban sustainability issues will benefit from this timely book. It will also prove to be a valuable read for urban planners and research consultants looking to widen their knowledge of the role of TOD in enhancing urban sustainability

Could sleeper trains replace international air travel?

Dutch airline KLM recently launched a new advertising campaign called “Fly Responsibly”. Remarkably, it seems to encourage viewers to fly less. “Do you always have to meet face-to-face?”, the advert asks. “Could you take the train instead?”. The influence of climate campaigner Greta Thunberg likely explains why airlines feel obliged to say these things. Flight shame – or “flygskam” – has gripped many regular flyers with a sense of unease about the aviation industry, which consumes five million barrels of oil a day and is predicted to account for around 22% of global carbon emissions by 2050. European high-speed rail networks already offer an alternative to air traffic between European countries for distances shorter than 1,000 kilometres. For longer journeys, sleeper trains are becoming increasingly popular. These services run through the night and offer passengers a berth to sleep in. As more and more consumers question the ethics of their next flight, rail companies see an opportunity – and competition with airlines is heating up. But can night trains help offset the international journeys that most people currently make by aeroplane

SU(3) Thermodynamics on Small Lattices

The free energy density of the SU(3) gauge theory at temperatures T/T_c = 4/3, 3/2 and 2 is calculated on lattices with temporal extent as small as N_t = 2, 3 and spatial extent N_s = 4 N_t using parametrized fixed point actions. Although cut-off effects are seen, they are hugely suppressed with respect to Wilson and Symanzik-improved actions and at N_t = 3 there is already a good agreement with the continuum limit as extrapolated from the results with the Wilson action at N_t = 6 and 8.Comment: 19 pages (latex text + 6 eps figures) in a uuencoded compressed tar fil
