Power of the Rank Adjacency Statistic to Detect Spatial Clustering in a Small Number of Regions

The rank adjacency statistic D is a statistical method for assessing spatial autocorrelation or clustering of geographical data. It was originally proposed for summarizing the geographical patterns of cancer data in Scotland (IARC 1985). In this paper, we investigate the power of the rank adjacency statistic to detect spatial clustering when a small number of regions is involved. The investigations were carried out using Monte Carlo simulations, which involved generating patterned/clustered values and computing the power with which the D statistic would detect it. To investigate the effects of region shapes, structure of the regions, and definition of weights, simulations were carried out using two different region shapes, binary and nonhinary weights, and three different lattice structures. The results indicate that in the typical example of considering Canadian total mortality at the electoral district level, the D statistic had adequate power to detect general spatial autocorrelation in twenty‐five or more regions. There was an inverse relationship between power and the level of connectedness of the regions, which depends on the weighting function, shape, and arrangement of the regions. The power of the D statistic was also found to compare favorably with that of Moran's I statistic.     

The best of times,the worst of times: Community-sector advocacy in the age of ‘compacts’

The recent introduction of written ‘compacts’ between government and community services organisations (CSOs) in Australia offers the promise of meaningful co-production of policy. However, recent research has highlighted that many in the community sector continue to perceive that there are significant constraints on their capacity to engage in advocacy. This paper examines the impact of the current governance regimes on the Australian community sector and explores the dimensions of these perceived constraints. The paper argues that both government and community sectors must make concessions and adjustments. Governments must accept that the use of contracting monopolies to stifle advocacy has weakened their capacity to deliver responsive services, while community organisations must accept that new governance regimes require new modes of participation in the policy process.

Innovative application of portable X-ray fluorescence (XRF) to identify Göktepe white marble artifacts

An efficient and non-destructive method to classify white marble artifacts by using a hand-held, portable XRF analyzer (pXRF) is here reported. The identification is based on the uniquely high strontium content of this marble and has been verified by testing 32 artifacts, most of which had already been provenanced, using conventional micro-destructive analyses. Besides strontium, other potential provenance indicators, such as manganese and iron, were analyzed and their concentration values obtained after empirical calibration of the instrument by using 17 quarry samples of known composition. The results show that Göktepe/non-Göktepe discrimination is almost always possible (30 artifacts) and that additional analyses are required only when the Sr value is at the lower edge of the Göktepe field (2 artifacts). The success of the method, however, resides in the particular composition relative to trace elements of Göktepe and is not easily extended to other marble varieties. Main reasons are related to insufficient accuracy at low concentration values, intrinsic trace variability of marble artifacts, surface effects that may produce not representative results. Interest in the method therefore is tightly linked to the exceptional importance of Göktepe as a sculptural marble, in which case, detailed data, obtained with a fast and totally non-destructive method, may provide relevant information concerning chronology, workshops, and places of production of the artifacts.     

Slingsby Bethel's Analysis of State Interests

Summary

Seventeenth-century thinking on the relationship between trade and state power was routinely conducted using the concept of state interests, which enabled users to conceive a Europe of competing states that managed the balance of power through trade and war. Poor interest management could arise from ignorance, error, or the divergence between the private interests of rulers and a state's true interests. The stakes of pursuing or neglecting true interest were high: the survival and prosperity of the state. The dominance of ‘mercantilism’ as a historiographical category has obscured the role of interest in early modern thought. This paper examines the work of one of England's most prolific interest writers, Slingsby Bethel, to demonstrate the importance of reading interest writings without recourse to mercantilism. The two focuses are, first, how the rhetoric of counsel was used to defend an ordinary subject's presumption to comment on state affairs and, second, the capacity for interest writers to construe the rise and fall of state power in terms of good laws and statesmanship.     

Mass Migration and the Polynesian Settlement of New Zealand

This paper reintroduces the concept of mass migration into debates concerning the timing and nature of New Zealand’s settlement by Polynesians. Upward revisions of New Zealand’s chronology show that the appearance of humans on the landscape occurred extremely rapidly, and that within decades settlements had been established across the full range of climatic zones. We show that the rapid appearance of a strong archaeological signature in the early 14th century AD is the result of a mass migration event, not the consequence of gradual demographic growth out of a currently unidentified earlier phase of settlement. Mass migration is not only consistent with the archaeological record but is supported by recent findings in molecular biology and genetics. It also opens the door to a new phase of engagement between archaeological method and indigenous Maori and Polynesian oral history and tradition.
