The strange geography of health inequalities

Place is undoubtedly relevant to health, and geography is a central character in the story of how rich societies handle inequalities in death and disease. But the text is incomplete, its scope limited by a too-delicate encounter between research and policy, and by a strange subdisciplinary divide. Accounts of the geography in health inequalities are largely, albeit subtly, locked into 'context'. They document the complex extent to which different (material, social and cultural) environments undermine or enhance resilience. They tell the tale of risky places. Our complementary narrative is written around the findings of qualitative 'compositional' research. It is about the way health itself is drawn into the structuring of society and space. This geography is a map of health discrimination, illustrated in the processes of selective placement, entrapment and displacement. By drawing attention to the 'healthism' of politics and policy in 'care-less' competition economies, this enlarged perspective might enhance the role of geography (and geographers) in both understanding and managing health inequalities.     

Computing geochemical mass transfer and water/rock ratios in submarine hydrothermal systems: implications for estimating the vigour of convection

A method of calculating chemical water/rock ratios is presented that enables the estimation of fluid velocities in open, flow‐through hydrologic systems. The approach is based on relating the gain/loss of a chemical species per kilogram of solid phase to the loss/gain of that species in the fluid phase, integrated across a specified length of the flowpath. After examining the underlying approximations of the approach using a one‐dimensional model of seawater moving through a basalt under nonisothermal conditions, the method is applied to representative zones within a two‐dimensional hydrothermal convective system. The method requires that regions within the flow system can be identified in which the direction of flow is steady for an extended period of time. Estimates of fluid velocity are spatial and temporal averages for the length of the flowpath used in the calculation. The location within the flow system and the nature of the alteration reactions determine which species can provide reliable values of the chemical water/rock ratio and useful estimates of fluid velocities. Over the length of the flowpath considered, the calculation of water/rock ratios works best when a species is controlled by a single reaction. Accurate estimates are favoured if the concentration profile of a species along the flowpath increases or decreases monotonically. If the length of the flowpath extends over more than one reaction zone, then erroneous estimates of the water/rock ratio and fluid velocity are more likely. Model calculations suggest that the quartz/silica system should provide reliable estimates for fluid velocity under a wide range of temperature and flow conditions, in particular in those regions of a system at or near quartz equilibrium, so that the aqueous silica concentration is buffered by quartz and correlated with the temperature distribution.

Avoiding Disaster: Diversification and Risk Management among East African Herders

This article addresses processes of livelihood diversification among pastoralists in the rangelands of northern Kenya and southern Ethiopia. The objectives of the article are threefold: (1) to suggest a theoretical framework for addressing income diversification among pastoralists with reference to current literature and databases; (2) to present a case study on pastoral income diversification based on preliminary field research in northern Kenya and southern Ethiopia; and (3) to summarize current understandings of pastoral diversification while pointing to additional empirical research needs. By showing how comparative analyses in the region have been constrained by theoretical and data deficiencies, the article explores ways in which income diversification differs by what are termed conditional, opportunity, and local response variables. Climate, distance to market towns, gender, wealth, and education are attributes covered by these variables and discussed in the article. The conceptualization and case study provide useful bases for conducting comparative research on pastoral diversification in East Africa specifically, and in sub‐Saharan Africa generally.     

The Archaeology of South Asian Cities

Urbanism in the Indian subcontinent occurred in three distinct time periods in which cultural cohesion over large regions is archaeologically demonstrated through the architecture and artifacts of social, ritual, and economic activity. In the Indus (2500–1900 B.C.) and Early Historic (3rd century B.C. to 4th century A.D.) periods, cities were not necessarily tied to political territories or guided by strong political leaders, but by the Medieval period (after the 9th century A.D.), urban zones were the base for political growth, warfare, and aggrandizement. The comparison of these three eras is undertaken within a framework for defining cities that balances quantitative criteria such as population size and areal extent with two types of qualitative criteria: internal specialization on the basis of materials found within archaeological sites, and external specialization on the basis of data recovered through regional analysis. Cities from the three eras also are evaluated from the perspective of the ordinary inhabitant through the examination of the social, religious, and economic factors that prompted and rewarded urban residence. While the Indus and Early Historic cities were attractive because of the networks of opportunity found there, Medieval cities additionally benefitted from a “push” factor as ordinary inhabitants allied themselves to urban areas in times of political stress and uncertainty.

Is there a place for children's geographers in the policy arena?

Despite a limited number of notable exceptions, children's geographers are not generally engaged with the policy process. Drawing on research carried out for the UK's Department for Education and Skills, this paper will argue that children's geographers are ideally placed to explore a number of important research questions appertaining to the impact of policy reform on children's lives. It suggests that by actively engaging with the policy process, we, as children's geographers, can bring a fresh and important perspective to the policy arena.

Fitting into a New Place: Irish Immigrant Experiences in Shaping a Canadian Landscape

Escaping one heritage of British colonialism for another, Irish immigrants to Canada in the nineteenth and early twentieth century helped to shape the image of Canada and Canadian nationalism. In this paper, I compare the diversity of Irish immigrant experiences in Canadas urban and wilderness landscapes. The Irish immigrant experience in major urban centers is well documented. Community neighborhoods, Church activities and domestic and manual labor constitute just part of the stories of urban Irish Canadians in cities such as Toronto. The popular conception of the Irish as strictly city people is strengthened by the lack of discussion of the Irish immigrant role in taming (and ideologically shaping) the wilderness of Western Canada. It is argued that this has to do with the colonial image of the Irish from which British imperialist Canada sought to distinguish itself.
