Water supply access in many developing countries is yet to fulfill Millennium Development Goals. Many local governments are incapable of managing their water resources either due to funding constrains or lack of adequate work force. This often results into poor services with low quality, insufficient and inconsistent delivery of water, leakage and wastage creating water shortages. The water str...

Search, Migration, and Urban Land Use: The Case of Transportation Policies We develop a search-matching model with rural-urban migration and an explicit land market. Wages, job creation, urban housing prices are endogenous and we characterize the steadystate equilibrium. We then consider three different policies: a transportation policy that improves the public transport system in the city, an ...

Environmental sustainability is one of the most critical issues worldwide, concerning every individual. The main objective in this area is to preserve scarce resources and reduce CO2 emissions in order to prevent environmental degradation. In recent years the potential of information systems (IS) as a driver for environmental sustainability has emerged under the term “Green IS”. Given that citi...

This paper uses a dynamic competitive spatial equilibrium framework to evaluate the contribution of rural-urban migration induced by structural transformation behavior Chinese housing markets. In model, technological progress drives workers facing heterogeneous mobility costs migrate from rural agricultural sector higher paying urban manufacturing sector. Upon arrival city, purchase using long-...

background: the objective of this study was to measure the total suspended particulate (tsp), pm 10 and pm 2.5 air particulates in the selected intercity bus stations located in the central square of hamadan, to review the distribution concentration of the air particulates content and to evaluate its possible health risk to the people who spent little time of their daily time in those places. m...

This paper presents a smart store that estimates a preference of consumers concerning products from their behaviors. This paper proposes a method, which is a passive observation and an active observation, to observe two behaviors, direct behaviors and indirect behaviors. The passive observation is a method to observe direct behaviors of customers towards real products through ambient sensors. T...

Bipartite projections have become a common way to measure spatial networks. They are now used in many subfields of geography, and among the most ways world city network, where intercity links inferred from firm co-location patterns. attractive because network can be indirectly readily available data. However, bipartite difficult analyze these networks weighted, larger weights do not necessarily...
