The role of urban heat islands and air pollution‚ PM2.5 and ozone‚ on human health is beginning to emerge. Lack of green space may have psychological effects for urban dwellers. We began to explore the nature of the urban environment and pollution on human health and well-being at UEP2010 in Boston in June of 2010. This very successful

ABSTRACT Most research in Machine translation is about having the computers completely bear the load of translating one human language into another. This paper looks at the machine translation problem afresh and observes that there is a need to share the load between man and machine‚ distinguish ‘reliable’ knowledge from the ‘heuristics’‚ provide a spectrum of outputs to serve different strata of people‚ and finally make use of existing resources instead of reinventing the wheel. This paper describes
