In an urban area the determination of transportation routes should be planned so as to minimize the provoked pollution taking into account the cost of such routes. In the sequel these routes are cited as pollution routes. The transportation network is expressed by a weighted graph ( ) , , , G V E D P = where every vertex represents a location to be served and E contains unordered pairs (edges) ...

That tax haven policies contribute to favorable economic growth in tax haven countries is commonly accepted. There is, however, minimal empirical evidence to substantiate this assertation and empirical investigations are subject to endogeneity bias. Using a sample of 155 countries from 1982 to 2003, we find that the standard tax haven variable is endogenous to the error term in a typical growth...

Objective: Metal concentrations in 53 soil samples of Shahr-e-Babak were determined.  Methods: Assessment of enrichment factor and geo-accumulation index revealed higher degree of contamination of Cd, Pb, and Cu in soil samples. Moreover, results of metal fractionation study revealed high amount of Cd and Pb are associated in weakly bounds may lead to environmental risk of these metals.  Result...

The US has been a global leader in regulating local air pollution and laggard greenhouse gases (GHGs). For decades, critics of policy have expressed fears that stringent regulations on would lead to havens overseas. Prior research, suggests not happened. But what about the converse fear? Are less climate causing become haven for other countries’ GHG-intensive industries? We provide decompositio...

Received: 30 June 2005 Revised: 30 December 2005 Accepted: 20 June 2006 Abstract The reconfiguration of the home-work boundary that at-home telework entails has significant implications for gender issues and the use of ubiquitous information and communications technologies (ICTs). By presenting a Marxinspired dialectical analysis of the family and home as both ‘haven and hell’, we develop a cri...

We propose new methods for estimating the bid-ask spread from observed transaction prices alone. Our methods are based on the empirical characteristic function instead of the sample autocovariance function like the method of Roll (1984). As in Roll (1984), we have a closed form expression for the spread, but this is only based on a limited amount of the model-implied identification restrictions...
