Cross-platform program for likelihood-based statistical comparisons of mortality profiles on a triangular graph

The construction of mortality profiles to investigate age-at-death patterns is a typical component of most faunal analyses. While many methods exist for constructing and comparing mortality profiles, plotting the percentages of juvenile, prime, and old individuals on a triangular graph, or ternary diagram, remains a popular method for making comparisons. Typically, these comparisons are made visually, but because sample sizes are often small, any differences may be the product of sampling rather than meaningful contrasts in depositional history. To overcome this problem, here we present a likelihood-based method for making statistical comparisons of mortality profiles on a triangular graph, and we make available a cross-platform computer program that implements the method. Although we developed the method with mortality profiles in mind, in principle, it can be used to analyze any kind of artifact for which there are three distinct categories.     

Trade's Value: Relational Transactions in the Papua New Guinea Betel Nut Trade

The betel nut trade in Papua New Guinea is big business. Betel nut, a mild indigenous stimulant, is considered the ‘green gold of the grassroots’. It is the country's most significant domestic cash crop and, in terms of rural incomes, a rival to the dominant export cash crops. Its sale is an important livelihood strategy in both rural and urban areas, the most visible manifestation of a flourishing informal economy. In betel nut marketplaces money ‘flows’ and ‘overflows’, traders wield large wads of cash, and vast sums change hands. Whether seeking their fortunes or only tinned fish, people trade betel nut first and foremost to make money, but such interests in trade do not automatically displace other forms of value. This paper is concerned with marketplaces and trade in contemporary Papua New Guinea and what is conveyed in those transactions between buyer and seller. Against the often impersonal and utilitarian rendering of trade, this paper seeks to foreground the sociability of trade and the multiple forms of value that may be simultaneously attached to monetised market transactions. This is not to conceal the discrete, unenduring, and competitive dynamics of trade, which prominently feature in many betel nut transactions, but instead to examine an important dynamic often overlooked. Market transactions, far from being asocial, or even socially destructive, have the capacity to generate and sustain diverse social relations including those of kinship and friendship.     

Hobbes and Schmitt

Many commentators are unconvinced by Carl Schmitt's interpretation of Hobbes's political theory which, to their minds, remakes Hobbes in Schmitt's own authoritarian image. The argument advanced in this essay comprises three claims about Hobbes and Schmitt and the ways in which they are construed. The first claim is that certain commentators are bewitched by a picture of authority which biases their own claims about Hobbes, perhaps in ways that they may not fully appreciate. The second claim relates to Hobbes's individualism. On Schmitt's account, it was this individualism that opened the barely visible crack in the theoretical justification of the state through which it was worm-eaten by liberalism. This essay argues that Hobbes's individualism is not what Schmitt or his critics take it to be. The individualism that figures in Hobbes's discussions of covenant and conscience, pace Schmitt, is an illusion, albeit one that lies at the very heart of his conception of the state and animates his understanding of the relationship between protection and obedience that sustains it. The essay concludes with some remarks about the wider implications of the argument it advances.
