A study of parametric versus non-parametric methods for predicting paleohabitat from Southeast Asian Bovid astragali

Studies of the African members of the family Bovidae have demonstrated the feasibility of using linear discriminant analysis to predict paleoenvironment based on measurements from postcranial skeletal elements. The use of discriminant analysis depends upon adherence to certain assumptions about the data set. In certain cases, these assumptions are violated, thus reducing the confidence of the results. The research presented here introduces the use of the non-parametric recursive partitioning method as a test of the linear discriminant method for predicting habitat from a collection of modern Bovid astragali from Southeast Asia. This study also provides a critique of the previous African studies. The results indicate that a combination of the parametric and non-parametric methods provides the highest prediction accuracy for Southeast Asian Bovids, though the independent methods do test favorably; thus providing an additional tool for archaeologists and paleoanthropologists in this region.     

Fiscal Federalism and Social Well–Being in Australia

Australia’s federal system is characterised by both vertical and horizontal financial imbalance. This is overcome by Commonwealth-state transfer payments. The nature of such transfers has changed over time as attempts have been made to redefine fiscal federalism. Currently, the budgetary position of the states, notions of co-operative federalism, and pleas for micro-economic reform are altering the nature of government activity as more and more is left to market forces. Patterns of social well-being are changing and increased inter-regional differences are evident. The current system of transfer payments can cope with this but detailed monitoring of social well-being is needed as is debate over the meaning of equity in the Australian federal system.     

Intervention: Mapping is critical!

This intervention targets the much heralded demise of the map in geography and the recently proposed “rethinking” of maps. It comprises contributions from two political geographers, a military geographer, a political scientist, and two activist cartographers and argues that there is not so much a need to “rethink” maps, but to “re-engage” with the material practices of mapping, and above all to “re-make” maps.     

Regional Weil-Being in Australia Revisited

There have been many studies of regional well-being in Australia, but few match the range of variables and spatial detail employed in this paper. Twenty two socio-economic variables were drawn from the 1986 census and used to classify all 148 Commonwealth electorates. Two procedures were adopted, both based on a principal components analysis, and compared to test the robustness of the classifications generated The first approach summed factor scores to provide a status index, and the second employed Ward's clustering algorithm. The resultant groupings are seen to both complement and reinforce each other and indicate the complex and often subtle variations in well-being across the country.
