Politywide Analysis and Imperial Political Economy: The Relationship between Valley Political Complexity and Administrative Centers in the Wari Empire of the Central Andes

This article tests a model for the political economy of the Wari Empire (AD 600–1000) of Peru. This model divides the empire into core and periphery zones. In the core, Wari political economy was organized to extract surplus agricultural production to feed the capital. In the periphery, the Wari strove to extract prestige goods. We suggest that there is a strong relationship between where the empire chose to locate its centers in the periphery and the political complexity of the local population in which the center was placed. We argue that in areas of low political organization sites should be located near the geographic center of a population. These sites will tend to function as local administrative centers geared toward the organization and exploitation of the area's wealth potential. In areas with more complex political organization sites should be located on the margins of a population. These sites should have functioned as gateway centers controlling, or at least profiting from, interregional exchange. Our model was systematically tested through the use of Geographic Information Systems (GIS). The results suggest that much of the variability found in Wari site placement in the periphery can be explained by differences in local sociopolitical complexity.     

Talk,technologies and teenagers: understanding the school journey using a mixed-methods approach

This paper focuses on the methods used in a project which set out to capture the movements and to consider the wellbeing of 30 teenagers on their journeys to and from school. A mobile phone linked to a GPS receiver was used to automatically log travel patterns whilst the respondents added ‘blog’ images and text about how they felt on the journey. Follow up interviews further explored the data. The paper shows that by using a range of methods the young people became involved in the project in different ways providing a rich picture of contingent and complex school journeys.     

Drought is normal: the socio-technical evolution of drought and water demand in England and Wales, 1893–2006

Water stress is becoming a permanent feature of life in Britain and other developed societies, and attempts to change ‘consumer behaviour’ are at the forefront of strategies for sustainability. This paper combines historical, geographical and sociological perspectives on the evolution of drought and water demand in modern England and Wales. Droughts have natural properties but their course, size and distribution is also the result of an interplay between governance, social norms and everyday practices. Focusing on seven significant droughts between 1893 and 2006, this article traces changing understandings of ‘normal’ water consumption and ‘rational’ demand and relates them to the evolving socio-technical management of water and identities of ‘the consumer’. We challenge the idea of a watershed between private supply (associated with passive ‘customers’) and public ownership (associated with active ‘citizens’). While private systems facilitated self-organised civic action more easily than public supply, the ideal of a citizen-contract blinded systems of public provision to the problem of expanding water use. An interdisciplinary analysis of droughts in the past offers lessons for the debate about sustainable consumption today.
