The hydrated title salt, [Cd2Cl2(C10H8N2)4](C9H5N4O)2·0.81H2O, was obtained from the hydro-thermal reaction between 2,2'-bi-pyridine, cadmium(II) chloride and potassium 1,1,3,3-tetra-cyano-2-eth-oxy-propenide. The binuclear cation lies across a centre of inversion in the space group P21/c, with the other components in general positions. The cation has approximate, but non-crystallographic 2/m s...

This paper constructs a theoretical model, in which transportation costs between two locations depend on cumulative infrastructure investment and governments allocate infrastructure spending over continuous space, thereby affecting the geographical pattern of transportation costs. Modelling international trade, we assume that governments set their infrastructure investment schedules in a non-co...

Considerable attention has been given to the efficiency-equity dilemma in explaining the territorial allocation of investment. However, centralization policies that seek to introduce or reinforce territorial hierarchies have yet to be subject to empirical analysis. Drawing on data from Spain, we show that investment in network modes is influenced by strategies of directing funding to the region...

The title compound, C9H8N2O2S3, crystallizes with two mol-ecules (A and B) in the asymmetric unit. Both have similar conformations (overlay r.m.s. deviation = 0.209 Å) and are linked by an N-H⋯O hydrogen bond. In both mol-ecules, the thio-phene rings show orientational disorder, with occupancy factors of 0.6727 (17) and 0.3273 (17) for mol-ecule A, and 0.7916 (19) and 0.2084 (19) for mol-ecule ...

This paper analyses from an empirical point of view the relationship between the provision of high-speed rail services (HSR) and the evolution of tourism at the local level in Spain. We have built a database of 124 municipalities during the 2005-2012 period to study the effects of the introduction of new HSR corridors on the number of visitors and their total and average stay at several end-lin...

In April 2009 the US government unveiled its blueprint for a national network of high-speed passenger rail (HSR) lines aimed at reducing traffic congestion, cutting national dependence on foreign oil and improving rural and urban environments. In implementing such a program, it is essential to identify the factors that might influence decision making and the eventual success of the HSR project,...
