AbstractIn this paper I analyse how the gradual reduction of research funds in Colombia can interrupt a key process in the generation of solutions to global urban problems. I draw on a bibliometric analysis to show that research funding flowing from North to South has created collaborations between researchers from North and South that have led to a better and more comprehensive understanding of the challenges facing cities around the world. To conclude, I propose four options to counteract these trends towards lower research funding.

AbstractUsing an exploratory space‐time analysis called spMorph, this article explores how the spatial distribution of international migration across the Spanish provinces has evolved over the period 1998‐2010. The chief advantage of this approach is that it permits the unambiguous identification of two key components in a spatial redistribution process, namely the shocks to the spatial distribution and the duration of regime fades. The results of the analysis show that administrative regions do not provide a reliable picture of the real dynamics in Spain's international migration distribution. In addition, the identification of two spatial shocks reveals the existence of three spatial regimes that consistently characterize the various phases that international migration has been through since the late 1990s.

This article makes an evaluation of the attacks to the infrastructure of the country made by the ELN and the FARC in the past ten years. Analyses concentrations, territorial and temporal displacement,and frequencies in the departmental level. The analysis suggests that, since the eighties, a large percentage of attacks was made by the ELN, but since the creation of the Caguan demilitarized zone, the FARC came to monopolize this attacks, articulating them, in a first period, to the peace conversations with the government. Once closed the Caguan demilitarized zone, the attacks became essentially defensive actions implemented to face the offensive of the government. We conclude that, although the attacks, the country has managed to maintain the operation of the infrastructure without major interruptions.
