Isotopic Determination of Seasonality in Diet and Death from Nubian Mummy Hair

Sections of human hair from naturally desiccated Sudanese Nubian mummies representing X-Group (AD 350-550) and Christian (AD 550-1300) periods in the Wadi Halfa area have been analysed for their isotope ratios. Because the carbon in hair represents food intake over the growth period of this tissue, analysis comparing segments taken next to the scalp with those further along the shaft can indicate diet just prior to death as well as any recent shift in food consumption. Modern populations in this area practise seasonal crop scheduling which involves the cultivation of C₃ plants (wheat, barley and most fruits and vegetables) in the winter and the hardier C₄ plants (sorghum and millet) in the summer. Shifting isotopic values along the length of hair strands of the ancient inhabitants of this area demonstrate that this practice has its roots at least as far back as the Initial Phase of Intensive Agriculture. The most common season of death appears to have been summer, the time of greatest climatic, nutritional and physiological stress for both ancient and modern inhabitants.

Rediscovering Australian federalism by resurrecting old ideas

The federal organisation of government in Australia is one of the least understood aspects of the Australian political system. Despite the durability of federal structures, federal theory in Australia remains largely underdeveloped. Aside from a few scholars who have persistently analysed the federal process, federalism in Australia has received attention as an outmoded system with little scope for distinguishing the benefits to be gained from understanding how government is organised. But where Australian federal theory has languished, American federal theory has flourished. This paper borrows some of the major ideas which have influenced analyses of government functions in the American ‘ system and posits them against analyses of Commonwealth and State government functions in Australia.     

Generalizing Impact Computations for the Autoregressive Spatial Interaction Model

We extend the impact decomposition proposed by LeSage and Thomas-Agnan (2015) in the spatial interaction model to a more general framework, where the sets of origins and destinations can be different, and where the relevant attributes characterizing the origins do not coincide with those of the destinations. These extensions result in three flow data configurations which we study extensively: the square, the rectangular, and the noncartesian cases. We propose numerical simplifications to compute the impacts, avoiding the inversion of a large filter matrix. These simplifications considerably reduce computation time; they can also be useful for prediction. Furthermore, we define local measures for the intra, origin, destination and network effects. Interestingly, these local measures can be aggregated at different levels of analysis. Finally, we illustrate our methodology in a case study using remittance flows all over the world.     

Mamihlapinatapai: Games People (Might) Play

With a focus on Melanesia, game theory is used to model the logical structure of strategic interactions between actors who engage in exchange transactions and to identify paradoxes, opportunities and uncertainties that confront those actors. It is argued that these exchanges are of three types which are named sharing, barter‐trade and prestige‐service. The first has the form of the classic game known as Prisoner's Dilemma and the expectation of non‐cooperation inherent in this game is resolved by trust. The second has the form of a game known as Chicken and the high risk inherent in this game is resolved by social manipulations that transform the payoff structure into Prisoner's Dilemma. The third is always an n‐person game. It has the form of a prestige game with an unconventional logical structure that is contingent on the existence of a parallel set of service games, each having the form of Chicken. The paper concludes by attempting to restore some realism to models that were over‐simplified abstractions. Some reinterpretations of conventional understandings are suggested.     

Using GIS to Identify Risk of Elevated Blood Lead Levels in Children in Adelaide

Environmental lead poses significant health risks to small children in most western countries. However, many surveys examining the prevalence of elevated paediatric blood lead levels give insufficient attention to the geography of the major known risk factors. GIS can address the spatial variation inherent in the distribution of these risk factors, and can identify areas, streets and even individual dwellings with a high probability of environmental lead. Predictions of risk can then be validated with analysis of blood or dust samples. This analysis forms the basis for a model predicting the presence and risk of environmental lead for any city and offers a means of targeting further investigation of lead exposure, more accurately estimating the number of children at risk using small area census data and selecting areas for future sample surveys. The need to develop a cost‐efficient and accurate method of modelling lead exposure risk in childhood is a task to which GIS is clearly well suited.
