The Bugiau Community at Eight‐Mile: An Urban Settlement in Port Moresby,Papua New Guinea

Contrary to the popular tendency to scapegoat and demonize urban settlements in Papua New Guinea the trend among academics has been to normalize their existence. There is however little detailed information upon which to base either view. This paper reviews existing studies of urban settlements in Papua New Guinea and finds a lacuna of information on basic livelihood functions. On the basis of a household survey and general observations made during a four‐week period of residence in an urban settlement in Port Moresby, it presents data on household composition, employment, income, expenditure and social identity for one urban settlement. The picture presented describes a way of life that does not support popular stereotypes.     

From 'industrial districts' to 'knowledge clusters': a model of knowledge dissemination and competitive advantage in industrial agglomerations

This paper integrates knowledge-based theories of the firm withgeograph-ical studies of industrial agglomeration to producea model that helps explain the competitive advantages enjoyedby proximate firms located in geographical clusters. We proposea hierarchy of specialized knowledge stocks at both firm andcluster levels and suggest that the comparative advantage conferredby knowledge resources at each level is protected, in part,by asymmetries in knowledge flows from level to level. The paperargues that codified component knowledge is more easily spreadthan firm-specific architectural knowledge. Nevertheless, overtime, agglomerations may develop a cluster-specific form ofarchitectural knowledge that facilitates the rapid disseminationof knowledge throughout the cluster by increasing the learningcapacity of proximate firms and thereby conferring cluster-specificcompetitive advantages.     

Cross-border mergers/acquisitions: a review and research agenda

Cross-border mergers/acquisitions account for the bulk of contemporaryforeign direct investment. Their significance, which is reinforcingthe position of transnational corporations as the dominant institutionalforce in the global economy, is related to the nexus of processesimplicated in international economic restructuring. Cross-bordermergers/acquisitions are, therefore, important influences uponthe evolution of the space economy, but this perspective onmerger/acquisition activity has been neglected in academic research.This review makes connections between disparate literaturesto identify potential lines of enquiry and attempts to situatethese lines of enquiry within current research agendas in economicgeography. On a basic level, mergers/acquisitions create newcorporate geographies which represent valid objects of researchin the geography of enterprise tradition. However, these corporategeographies are set within the institutional context of social,economic, and political relations. Many of the most interestingresearch questions derive from these contextual relations whichare addressed with reference to issues of embeddedness at variousgeographical scales and also by linking these issues to aspectsof employment and territorial development.     

Assessing the applicability of portable X-ray fluorescence spectrometry for obsidian provenance research in the Maya lowlands

Recent innovations in portable energy-dispersive X-ray fluorescence (PXRF) spectrometry have increased its utility for the geochemical characterization of obsidian artifacts for archaeological provenance research. However, concerns over the utility of PXRF instrumental analyses have been raised, focused on the validity and reliability of the geochemical data produced. Here we adopt the framework of Richard Hughes (On Reliability, Validity, and Scale in Obsidian Sourcing Research, 1998), whereby reliability addresses instrument stability and issues of measurement while validity pertains to an instrument’s ability to discern geochemical source provenance. This is done in order to test the utility of PXRF instruments for archaeological provenance research. k-Means cluster analysis was used to test the accuracy of PXRF through statistical comparison of data acquired via laboratory and portable energy-dispersive XRF instruments. Multivariate analysis was employed to demonstrate obsidian source representation at two Classic Maya archaeological sites in southern Belize – Uxbenká and Ek Xux – and to test the validity of data obtained from a PXRF instrument in answering archaeological research questions pertaining to regional interactions between lowland Maya polities. Results suggest that portable XRF instruments produce internally consistent results. However, data acquired from a PXRF instrument are not statistically equivalent to other XRF instruments. This is to say that while PXRF is not a reliable technique, it is valid for questions pertaining to geochemical source representation.     

What Were We Thinking?

This article outlines the context in geography and statistics in the mid 1960s, at the height of geography's so-called "quantitative revolution," that led us into a long-term collaboration about spatial statistics, which has continued in surges and lulls for some 40 years. We focus upon problems in spatial autocorrelation, including the measurement of autocorrelation, distribution theory, and variable geographical lattices. This narrative may not describe how it was, but it does describe how we remember the events of the time.     

Taphonomy and zooarchaeology of a high-altitude Upper Pleistocene faunal sequence from Hovk-1 Cave,Armenia

The Caucasus is a key region for the study of hominid evolution and Neanderthal ecology. Taphonomic and zooarchaeological studies of sites from this region are few and only focused on sites at low-to-mid altitude zones with evidence of relatively intensive hominid occupation. This study focused on the taphonomic and zooarchaeological characteristics of a high-altitude site from the Upper Pleistocene – Hovk-1 Cave – looking at diachronic change in both natural and cultural processes which shaped the faunal assemblage. Results best fit a model in which the bones of most large mammals, mainly ungulates (wild goat, Capra aegagrus and red deer, Cervus elaphus) and cave bears (Ursus spelaeus) accumulated naturally through pitfalls, with minimal input from human or carnivore activity. This accumulation is characterized by a high frequency of complete ungulate and carnivore bones, a bear assemblage which is dominated by young-adults and a wild goat assemblage that includes juvenile and young-adult individuals. Our taphonomic reconstruction serves as a point of reference for comparative studies of palaeoenvironments and human subsistence patterns of Middle and Upper Palaeolithic sites in the Caucasus and broadens our perspective on hominid occupation and ecological adaptation in other high-altitude world regions.
