Mapping Submerged Landscapes Using Multibeam Bathymetric Data: a case study from the north coast of Ireland

This paper outlines work currently being undertaken to reconstruct submerged archaeological landscapes off the north coast of Ireland. This research uses the recently‐completed Joint Irish Bathymetric Survey (JIBS), which has provided full‐coverage high‐resolution multibeam bathymetric data for the sea‐bed off the north coast. This data has been examined for evidence of past sea‐level change and been used to produce palaeo‐geographic reconstructions of the past landscape, which in turn have facilitated the identification of ten areas of high archaeological potential. The results presented here will form the basis of a future programme of archaeological survey and prospection. © 2010 The Authors     

Characterization of New Zealand obsidian using PXRF

New Zealand has some of the most active areas of rhyolitic volcanism in the world and this has produced numerous obsidian sources in the northern half of the North Island. In total archaeologists have recognized 27 named locations from which obsidian can be obtained scattered across 4 geological source regions. Shortly after colonization in the late 13th century AD Polynesian settlers began transporting this material some thousands of kilometers throughout the country and across the sea in small quantities to distant neighbors in the Kermadecs and Chatham islands. Although considerable research has been conducted on obsidian sourcing in New Zealand the complexity of geochemical source discrimination and the lack of a practical method of non-destructive geochemical analysis has hindered progress. We present the results of our use of PXRF to provide geochemical data on New Zealand obsidian sources and to compare the use of discriminant analysis and classification tree analysis to discriminate among sources and attribute archaeological samples to sources. Our research suggests that classification tree analysis is superior to discriminant analysis in sourcing studies. A large case study using an important settlement phase site (S11/20) from the Auckland region demonstrates the utility of the methods and the results support a model of high degrees of mobility and interaction during the early settlement of New Zealand.     

Vagrant,Convict, Cannibal Chief: Abel Magwitch and the Culture of Cannibalism in Great Expectations

Charles Dickens’s Great Expectations opens with a jolt, as Abel Magwitch – an escaped convict – pounces on the narrator and protagonist, Pip. Despite this rather dramatic introduction, and the pivotal role that he goes on to play in the plot, Magwitch has never been given the sustained critical analysis that he warrants. More often than not he has been treated as one of Dickens’s infamous ‘flat’ characters; a kind of ‘pantomime wicked uncle’, in the words of George Orwell. This is a critical legacy that this paper seeks to redress. Seeing Magwitch as an essential element in Dickens’s critique of mid nineteenth-century society, this paper examines Magwitch’s largely ignored peripatetic and homeless past. By contextualizing Magwitch in his role as a vagrant outsider, and then exploring how this marginal position nuances the cannibalistic appetite he displays in the first pages of the novel, I argue that Magwitch’s violence and ‘savagery’ forms a foil for the more sadistic practices of civilized society. In doing so I position Magwitch at the dark heart of Dickens’s social pessimism, and re-evaluate the culture of cannibalism that we see in Great Expectations.     

A Micro Model of Problem Definition and Policy Choice: Issue Image,Issue Association,and Policy Support of Power Plants

Past research on problem definition and public policy primarily focuses on the macro-system level. In this study, we propose a micro model of problem definition and policy choice at the individual level. We argue that while individual citizens' problem definitions and policy preferences are rooted in and filtered through their predisposition characteristics (such as socioeconomic status, political orientation, and informational base), their policy choices also strongly depend on how they define public issues, particularly how they perceive the image of an issue at hand and how they associate the issue with other public issues. Our empirical analyses, based on data from a national public survey on energy and power plant issues, support the key propositions derived from our theoretical model. Key contributions to and implications for policy studies are discussed in conclusion.
