A Test of Ideal Free Distribution Predictions Using Targeted Survey and Excavation on California’s Northern Channel Islands

Using targeted survey, excavation, and radiocarbon dating, we assess the extent to which human settlement patterns on California’s northern Channel Islands fit predictions arising from the ideal free distribution (IFD): (1) people first established and expanded permanent settlements in the regions ranked high for environmental resource suitability; (2) as population grew, they settled in progressively lower ranked habitats; and (3) changes in the archaeological record associated with high population levels such as increases in faunal diversity and evenness in high-ranked habitats are coincident with the expansion to other areas. On Santa Rosa Island, the early permanent settlements were located in both high- and middle-ranked locations, with the most extensive settlement at the highest ranked locations and only isolated sites elsewhere. Settlement at a low-ranked habitat was confined to the late Holocene (after 3600 cal BP). Drought influenced the relative rank of different locations, which is an example of climate adding a temporal dimension to the model that episodically stimulated population movement and habitat abandonment. Because the IFD includes a wide range of cultural and environmental variables, it has the potential to be a central model for guiding archaeological analysis and targeted field research.     

Path dependence,policy learning and Australian manufacturing since the 1970s

The impending demise of passenger motor vehicle manufacturing in Australia provides a good opportunity to view the trajectory of industry policy since the Whitlam government commenced the process of tariff cuts in 1973. It is argued that industry policy over this period demonstrates the effects of path dependence and a lack of policy learning. In the industry policy context, the path dependence perspective suggests three key factors in explaining policy effects: the importance of initial conditions; the role of cumulative causation in the interaction between policy settings, actors and firms; and the shaping role of networks. While political or electoral factors could, on occasion, generate support for threatened industries, overall, neo-liberal policy ideas guided decision-making. An examination of Australian defence industry, and a comparison of the Australian and New Zealand dairy and milk processing industries reinforces the importance of institutionally shaped path dependency.     

A Fisk patent metallic burial case from Western Missouri: an interdisciplinary and comprehensive effort to reconstruct the history of an early settler of Lexington,Missouri

In 2006 a cast-iron coffin was discovered in an unmarked burial plot in Lexington, Missouri. A multifaceted investigation was conducted to provide historical documentation and possible identification of the individual. The coffin is an early Fisk Patent Metallic Burial Case. Osteological analyses indicate that the skeletal remains belong to a 20 to 30 year old white female who consistently ate an omnivorous diet with significant amounts of C4 plants or seafood. Rib morphology and her burial garments suggest she frequently wore restrictive clothing. No gross skeletal pathological lesions or trauma were observed except for a patch of reactive bone and an atypical pattern of bone remodeling on the visceral surface of the sixth rib. Subsequent bacterial DNA analysis of the ribs and sternum indicate the presence of tuberculosis infection. Although not conclusive, multiple lines of evidence are consistent with the skeletal remains representing Elizabeth (Triplett) Stewart who died in 1854 of pulmonary tuberculosis. This multidisciplinary research significantly contributes to the local history of Lexington, Missouri and provides a likely identification of the deceased individual for the Stewart Family.     

Trust and Confidence: A Study of Young Queenslanders

This paper provides a unique perspective on trust in Australian society using data from the first wave of a longitudinal study of young people in Queensland. Questions central to young people's expectations regarding institutions and significant others are interrogated. Trust assumes critical importance in this context because it is an important aspect of the future-oriented deliberative processes young people engage in. Gender, indigenous status and religiosity are key determinants of trust across a range of indicators. Boys are less likely than girls to trust significant others such as friends and siblings or to trust environmental groups, but are more trusting of sportspeople, television and the Internet. Aboriginal children are more trusting of their siblings, teachers and neighbours, but less so of their parents. ‘Smart’ children are more trusting of their teachers and schools and feel more confident about their future, while general life satisfaction is positively associated with most measures of trust.     

"The Problem of Spatial Autocorrelation" and Local Spatial Statistics

This article examines the relationship between spatial dependency and spatial heterogeneity, two properties unique to spatial data. The property of spatial dependence has led to a large body of research into spatial autocorrelation and also, largely independently, into geostatistics. The property of spatial heterogeneity has led to a growing awareness of the limitation of global statistics and the value of local statistics and local statistical models. The article concludes with a discussion of how the two properties can be accommodated within the same modelling framework.     

Reconstructing site organization in the eastern Aleutian Islands,Alaska using multi-element chemical analysis of soils

This study presents the results of multi-element analysis of weak-acid extractions of 953 soil samples collected by coring on and around pre-historic village sites on two islands, Sanak and Amaknak, in the eastern Aleutians. Concentrations of aluminum (Al), barium (Ba), calcium (Ca), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), phosphorus (P), strontium (Sr), titanium (Ti), and zinc (Zn) were determined using an inductively coupled plasma-mass spectrometer (ICP-MS). Resultant elemental signatures allow the identification of site features and organization in the absence of large-scale excavation. All the archeological sites showed similar and distinct chemical signatures regardless of the several thousand year date range of the sites or the length of time a site was occupied. However, intensity of occupation does appear to affect concentrations of elements. Site features such as houses, house berms, house floors and middens had distinct anthropogenic signatures and could be distinguished from one another. This approach may be used to identify sites that do not have distinct surface features and to target areas for excavation.     

When Policy Goes Wrong: The Problem of Transmitted Risk

Why do policies fail? There are many answers to this question, and many ways of answering it. In this paper, we use the tools of policy framing and systems thinking to investigate two recent Australian examples of public policy failure, each involving a different policy milieu and time-span. We show that, in both these cases, unintended consequences arose because governments lost control of the implementation process while remaining politically accountable for the outcomes. We develop the concept of transmitted risk to show how this occurred. We argue that governments expose themselves to this kind of risk when they make policy decisions involving a combination of excessive incentives and poorly controlled third parties.
