Financialization,totality and planetary urbanization in the Chilean Andes

In a context of planetary urbanization, where vast swathes of the countryside are being enclosed on an ongoing basis in order to support a sprawling urban system, the relationship between finance and land-use change needs to be brought to the forefront. By engaging with Henri Lefebvre’s ideas of levels and totality, this paper draws analytical connections between the financialization of the transnational mining industry and the production of the financialized urban everyday in geographies of extraction. The paper does this by looking at the case of Pascua Lama, a multibillion open-cast mine to be developed in Chile by a major mining company in the context of the current global gold rush. Through this case, I show how a set of strategies pursued by financiers and corporate managers thousands of kilometers away from the extraction site, resulted in fractured spaces of urbanization shaped by socioecological plunder, dispossession and geographically uneven financial landscapes.     

Inelastic torsional response of buildings to the 1985 Mexican earthquake: a parametric study

This study aims to determine the influence of torsional coupling on the inelastic response of a series of models representing typical structural configurations in real buildings. The lake bed (SCT) east-west component of the 1985 Mexico City earthquake was employed in the analysis, and is representative of a severe ground motion known to have induced large inelastic structural deformations in a high proportion of those buildings having asymmetrical distributions of stiffness and/or strength. Material non-linearity in lateral load-resisting elements has been defined using a hysteretic Ramberg-Osgood model. Structural eccentricities have been introduced into the building models by (i) asymmetrical distributions of stiffness and/or strength, (ii) asymmetrical configuration of lateral load-resisting elements, or (iii) varying post-elastic material behaviour in the resisting elements. The dynamic inelastic response of these models has been obtained by a numerical integration of the relevant equations of motion, expressed in a non-dimensional incremental form.

In the elastic range, the results correlate well with those of previous studies. In the inelastic range, it is concluded that the peak ductility demand of the worst-affected element increases with the ground excitation level across the range of building periods considered, and that the influence of torsional coupling on the key response parameters is model dependent. Most significantly, the strength eccentricity relative to the centre of mass has been shown to influence the peak edge displacement response more than conventionally employed stiffness eccentricity.     

First‐order exchange coefficient coupling for simulating surface water–groundwater interactions: parameter sensitivity and consistency with a physics‐based approach

Distributed hydrologic models capable of simulating fully‐coupled surface water and groundwater flow are increasingly used to examine problems in the hydrologic sciences. Several techniques are currently available to couple the surface and subsurface; the two most frequently employed approaches are first‐order exchange coefficients (a.k.a., the surface conductance method) and enforced continuity of pressure and flux at the surface‐subsurface boundary condition. The effort reported here examines the parameter sensitivity of simulated hydrologic response for the first‐order exchange coefficients at a well‐characterized field site using the fully coupled Integrated Hydrology Model (InHM). This investigation demonstrates that the first‐order exchange coefficients can be selected such that the simulated hydrologic response is insensitive to the parameter choice, while simulation time is considerably reduced. Alternatively, the ability to choose a first‐order exchange coefficient that intentionally decouples the surface and subsurface facilitates concept‐development simulations to examine real‐world situations where the surface‐subsurface exchange is impaired. While the parameters comprising the first‐order exchange coefficient cannot be directly estimated or measured, the insensitivity of the simulated flow system to these parameters (when chosen appropriately) combined with the ability to mimic actual physical processes suggests that the first‐order exchange coefficient approach can be consistent with a physics‐based framework.

INTELLECTUAL COHERENCE AND THE FOUNDATIONS OF GEOGRAPHY

The discipline of geography needs a more clearly defined academic purpose if it is to retain and enhance its position as an essential university subject. The discipline lacks the intellectual coherence it once achieved on the basis of environmental determinism. Geographers could re-establish a coherent intellectual foundation for geography by adopting a historical-intellectual mode of enquiry focusing on human thought and ideas and re-emphasizing the central importance of the human-environment relationship as the foundation of the discipline. An understanding of human activity in the environment in relation to ideas could provide a clearer focus for the discipline of geography and give it a stronger intellectual identity.
