Unsafe drinking water quality in remote Western Australian Aboriginal communities

Chronic kidney disease (CKD) is important in the fields of public health and health geography because of its heavy burden on the health system and high cost of treatment in its advanced stages. The causes of CKD are associated with diabetes and hypertension, but in some parts of the world, the disease occurs in the absence of these factors. Researchers identify this condition as CKD of “unknown” causes (CKDu). CKDu is a multi‐factored health problem and one suspected causal factor is contaminated drinking water. The disease occurs globally but is found in particularly high concentrations among people of certain ethnic and disadvantaged social groups living in very different locations around the world. CKD has become endemic in Western Australia where hospital admissions for Aboriginal people requiring renal dialysis or treatment for diabetes are much higher than for the general population. The possible proportions of CKDu cases among the CKD patients are unknown. This study examines the drinking water quality among communities such as these. Water chemistry analysis in these areas indicates that the nitrate and uranium content greatly exceed officially recommended levels. Most of these communities rely on raw groundwater to supply their domestic needs, and it is very likely that the people are unwittingly ingesting high levels of nitrates and uranium, probably including uranyl nitrates. Very few such remote communities have access to treated drinking water, and cost‐effective water treatment systems are required to provide potable water at the local scale.     

The Making of Mitteldeutschland. On the Function of Implicit and Explicit Symbolic Features for Implementing Regions and Regional Identity

Abstract: According to the theory of 'significative regionalisation' (Werlen), territorial entities may be understood as products of symbolic practices. However, the assumption that regions are not only made but also continuously performed in acts of communication effects the character of substantial research into ostensible and latent spatial imaginations apparent in communication processes. In this article, the reactivation of Mitteldeutschland (literally the 'centre of Germany') in a televisionseries about the region's history is the empirical starting point for conceptualizing contemporary processes of symbolic regionalization. The approach taken covers the entire communication chain from the editorial process to the film material up to everyday language use of the programs target group. Three empirical studies with specific methods of research (hermeneutics, argumentation analysis and semi-structured interviews) illustrate this interlinked process. As an analytical tool, a fundamental distinction between implicit 'common places' of spatial representation and more obvious and thus negotiable explicit features of spatial signification is suggested. The analysis elucidates that — even under conditions of contemporary globalization — the massmedia reproduce traditional practices of spatial representation, as, for instance, a persistent and taken-for-granted use of container images indicates. Regarding the explicit features, however, the medias' influence seems to be quite low. Mitteldeutschland's geography, as proposed by the television program, is questioned and negotiated in everyday symbolic practice. Up until now, the region thus remains continuously 'under construction'.     

Antebellum Southern Political Economists and the Problem of Slavery

This article seeks to contextualize the political economists of the antebellum South. The article analyzes them both as members of a transatlantic set of economic thinkers and as southern defenders of slavery. As such, they paired a commitment to the fundamental precepts of classical economics with a defense of chattel slavery. Some historians have claimed that the simultaneous commitment of the southern political economists to political economy and slavery compromised both their social science and their defense of slavery. In contrast, this article finds that the southern political economists exploited the gaps and tensions in classical political economy on the topic of unfree labor to build a coherent and popular economic defense of slavery. Key to the defense was a view of planters as profit‐seeking capitalists and a racism that necessitated the control of black laborers. In the process of developing the defense, some of the southern political economists championed the prospect of industrializing the economy of the South with surplus slave labor.
