A new method for modelling archaeological resource potential is presented that avoids some of the mathematical violations and inconsistencies of previously-favoured techniques. The Minanha research area in west-central Belize and a database of other Maya centres from within Belize are used as a case study for demonstrating the utility of the proposed modelling technique.  相似文献

A key area in the analysis of urban structural evolution is identifying discontinuities. Effective analysis could improve long‐term forecasting and provide a better understanding of how to steer an urban system toward a desirable future state. We use a simple aggregate retail model to demonstrate an algorithm for identifying discontinuities in model parameter space. Explorations of retailing in both Greater London and South Yorkshire in the United Kingdom illustrate how understanding a system's potential for discontinuity can provide insights for both policy makers and retail businesses. The Harris and Wilson model, described in the section so‐named, is used as a simple archetype to illustrate the new framework. This model can be developed in a straightforward way to incorporate further refinement. In “ Executing the model and visualizing the results ,” we describe a single model run and in “ Investigating discontinuities ,” we explain our framework for detecting and analyzing discontinuities. “ Identifying discontinuities in the London retail system ” shows the results of applying this methodology to the Greater London retail system, and in “ Practical applications ,” we explore the policy applications for this technique as related to the decline of town centers in the South Yorkshire retail system. Some concluding comments are offered in “ Conclusions .”  相似文献

Since 2005, a burgeoning wave of Chinese investments has set off a new ‘minerals boom’ in the Australian iron ore and coal mining sectors. While normally a welcome development, the state-owned and strategic nature of the investors has raised concerns in Australia about how these should be regulated. As a result, in February 2008 the Australian government declared an intention to more closely screen foreign direct investment (FDI) from state-owned sources, which both supporters and detractors alike have claimed is evidence of ‘resource nationalism’ in Australia's approach towards its trade and investment relationships with China. This article challenges this understanding through an examination of the characteristics of Chinese mining FDI, the dilemmas these present to the Australian government, and the relatively restrained nature of its response. Through this, Australia's FDI policy is explained as a defensive move against the potential for strategic behaviour by Chinese investors resulting from their state ownership, rather than any national program to subject minerals trade and investment to political control. On this basis, the article argues that Australian government policy instead evidences a ‘resource liberalism’ approach, which intends to ensure that the governance of Australia's minerals trade and investment with China remain market-based processes.  相似文献

This paper outlines the archaeological evidence found at the demolished Royal Naval Dockyard at Woolwich for the development and construction of dockyard structures of the 18th to early‐19th centuries. This is set within the framework provided by historic, documentary, map and historic‐model evidence. The results of earlier excavations at the same facility are also reviewed. The themes covered include; the interplay of ‘carpentry’ versus ‘shipwrightry’ in dockyard construction, aspects of naval timber‐supply and landscape, the recycling of ships' timbers, dockyard craft specialisation and changing relative sea‐levels. © 2011 Pre‐Construct Archaeology Limited  相似文献

Bedwetting has confounded the presumed boundaries of the human body, existing in a fluid space, between the normal and pathological, its treatment has demanded the application of a wide array of different technologies, each based on a distinct conception of the relationship between the body and personality, human organs and personal conduct. In tracing the social history of bedwetting and its regulation, this article examines the ontological assumptions underpinning the treatment of bedwetting and how they have changed over the past two centuries. Through the analysis of medical journals, newspaper articles and magazine advertisements, different topologies are identified which redefine the boundaries of the human body and its capacities. From 16th-century naturalism, in which the human body is subordinated to a cosmic totality, to the circumscribed space of 19th-century paediatrics and the expansive circuits of behavioural psychology and modern psychoanalysis, the body has become multiplied, differently enacted through the application of diverse technologies. It was be shown how coordinating the messy and divergent conceptions of the human body has posed an endemic problem for the human sciences, and how the enduring tension between object enactment and subject constitution is an expression of modern "baroque" subjectivity.  相似文献
