Our analysis of this period pays particular attention to how these reimagined Leichhardts emphasise or neglect some of the key elements that make up his story to this day, among them: Leichhardt's ethnicity; his sense of attachment to place and home; his homosocial relationships; his evasion of Prussian military service; his role in the British colonial project; and finally, his engagements with Aborigines. On the one hand, our analysis reveals, how Leichhardt was portrayed first on the local and, later, the national level in ways that increasingly sought to elide ambiguous aspects of his life and deeds. However, it also uncovers some of the ideological labour required to render him useful to the National Socialist cause. Often enough, these re-imagined Leichhardts escaped party politics, and cast up some of the logical inconsistencies and limits to key terms in National Socialist thinking.}, language = {en} } @article{LeyCooperViezzoliGuillemoteauetal.2015, author = {Ley-Cooper, Alan Yusen and Viezzoli, Andrea and Guillemoteau, Julien and Vignoli, Giulio and Macnae, James and Cox, Leif and Munday, Tim}, title = {Airborne electromagnetic modelling options and their consequences in target definition}, series = {Exploration geophysics : the bulletin of the Australian Society of Exploration Geophysicists}, volume = {46}, journal = {Exploration geophysics : the bulletin of the Australian Society of Exploration Geophysicists}, number = {1}, publisher = {CSIRO}, address = {Clayton}, issn = {0812-3985}, doi = {10.1071/EG14045}, pages = {74 -- 84}, year = {2015}, abstract = {Given the range of geological conditions under which airborne EM surveys are conducted, there is an expectation that the 2D and 3D methods used to extract models that are geologically meaningful would be favoured over ID inversion and transforms. We do after all deal with an Earth that constantly undergoes, faulting, intrusions, and erosive processes that yield a subsurface morphology, which is, for most parts, dissimilar to a horizontal layered earth. We analyse data from a survey collected in the Musgrave province, South Australia. It is of particular interest since it has been used for mineral prospecting and for a regional hydro-geological assessment. The survey comprises abrupt lateral variations, more-subtle lateral continuous sedimentary sequences and filled palaeovalleys. As consequence, we deal with several geophysical targets of contrasting conductivities, varying geometries and at different depths. We invert the observations by using several algorithms characterised by the different dimensionality of the forward operator. Inversion of airborne EM data is known to be an ill-posed problem. We can generate a variety of models that numerically adequately fit the measured data, which makes the solution non-unique. The application of different deterministic inversion codes or transforms to the same dataset can give dissimilar results, as shown in this paper. This ambiguity suggests the choice of processes and algorithms used to interpret AEM data cannot be resolved as a matter of personal choice and preference. The degree to which models generated by a ID algorithm replicate/or not measured data, can be an indicator of the data's dimensionality, which perse does not imply that data that can be fitted with a 1D model cannot be multidimensional. On the other hand, it is crucial that codes that can generate 2D and 3D models do reproduce the measured data in order for them to be considered as a plausible solution. In the absence of ancillary information, it could be argued that the simplest model with the simplest physics might be preferred.}, language = {en} }
