Between 2012 and 2019, Manus Island, Papua New Guinea, hosted Australia's offshore detention centre for asylum seekers and refugees, known as the Regional Processing Centre (RPC). This paper analyses some of the social impacts of the RPC on Lorengau town, the urban centre of Manus, through the analytical lens of the Manus idiom, as basket (Tok Pisin). Materially this refers to the everyday Manus basket whilst metaphorically, it refers to an individual's or community's social, cultural, political and economic base. First, I examine asylum seekers and refugees as a social category that emerged during this period when they were referred to as papu by locals. Papu is an honorific kinship term for grandfather or elder man; for men who are symbols for family identity, social belonging, and rights to land. Second, I examine the changing materiality of Lorengau's markets as indicative of wider societal transformations and dissonance brought about by the RPC. My ethnographic data are based on long term involvement in Manus, including three recent visits to Lorengau in 2017, 2018, and 2019 where I studied the social impacts and the changing social practices of Manus people in response to the RPC.  相似文献

Kuwait–Georgian archaeological work at Failaka Island showed the need for geological study. Analysis of sediments related to drinking water-collecting cisterns was performed on a Late Islamic settlement (NE part of the island) in 2018. Field sedimentological, grain size and XRD analysis of the sediment profiles showed that the shallow (about 1 m deep) cone-shaped wells are dug in the loose, porous, cross-stratified calcareous coarse-grained quartz sandstones. Three upper layers of quartz sandstones in the profile have high infiltration rate and provide a rare yet ideal material for water retention. The fourth dense layer below, composed of very fine sand and silt fraction, tends to hinder water movement and forms a relatively impermeable water-resistant surface. Thus, the distribution patterns of clay content, grain sizes and porosity of the well-hosting sediments are favourable for freshwater infiltration and harvesting. An additional petrographic analysis was conducted on different types of rocks discovered on the archaeological site, used as building material and fragments of stone artifacts to identify their origin. It was established that archaeological building material is of local origin, whereas the source rocks for stone artifacts were imported.  相似文献

Much practically orientated environmental research is marked by a polarity between functionalist abstraction and ahistorical normative discourse. This paper seeks to bridge the divide between theoretical and empirical research through a case study of New York City's water supply. Current processes of socio-economic restructuring are leading to negative environmental consequences obscured by a failure to extend analysis beyond limited temporal, spatial or sectoral scales. Insights from regulationist theory show that a combination of fiscal, political and other developments are bringing about a wide-ranging reformulation of existing patterns of environmental regulation and service provision in the city. The power of the state is being radically diminished in relation to the power of capital and a plethora of different interest groups. A relatively simple centralized model of environmental regulation is being transformed into a complex decentralized pattern involving the emergence of new approaches to urban governance. Further research is needed on the contradictions between capitalist accumulation and environmental regulation at different spatial scales in order to link New York's changing role within the global economy to the declining political legitimacy and fiscal capability of the state to play an extensive role in environmental management.  相似文献

This study takes a valuation perspective to study how and where products and innovations are gaining ‘economic significance’ in the contemporary economy. Building on a recent research stream in economic geography and urban and regional studies, it highlights that the economic value of many products is not formed within production systems alone, but relies on co-constructed connections between production and consumption systems, playing out across multiple geographies. It distinguishes between three types of economic valuation pathways – namely technical, experiential and identity-based – which although analytically distinct may actually build and reinforce one another. This approach is empirically illustrated with the case of the surf-related economy in the city of San Sebastian (Basque Country, Spain), which is used to make a broader point about the growing relevance of a valuation approach to understand competitive advantage and economic renewal in localized production systems.  相似文献

What is the role of material culture in understanding the past? This review essay explores two principal approaches—the history of museums and antiquities and environmental history—to reflect on their shared investment in historical materialism. It reviews Timothy LeCain's The Matter of History and Peter Miller's History and Its Objects, discussing their perspectives on objects and the writing of history. One important part of this history concerns the relationship of academic historians to the idea of a history museum, curatorial practices, and public history. What kinds of history can we do in a museum, with things, that might not occur without the presence of objects? Why were nineteenth- and early twentieth-century efforts to encourage a close relationship between historical research and the history museum largely abandoned in favor of a document-driven approach? The second dimension of current interest in historical materialism concerns new approaches to environmental history. It draws inspiration from Deep History as well as recent work in archaeology and STS (Science and Technology Studies) to argue for a more integrated history of humans and nature that demonstrates how things have made us. The history of successive efforts to remake the environment in different parts of the world and their consequences offers crucial object lessons in how humans have responded to nature's own creativity. Both approaches to historical materialism highlight the virtues of a more interdisciplinary approach to historical scholarship, in the museum or in the field, but most important, in our own sensibilities about what it means to think historically with artifacts and to treat them as compelling evidence of a shared history of humanity and nature.  相似文献

Tallis’s Street Views describe London as a commercial and professional centre but the visual representation of the street elevations gives an impression of quiet emptiness; it is hard to get a sense of the activity in and around the businesses portrayed. The household inventory of one of Tallis’s advertisers, a dentist who died in 1850, suggests a way of redressing this. An interpretive reading of the list of the dentist’s belongings, disposed around the different spaces of the premises, which housed his residence, his business and other households, gives some sense of the complexity and struggle at a daily level behind Tallis’s apparently orderly professional and commercial facades. This indicates that we can look more generally to material culture – whether in textual and visual representations or as actual artefacts – to provide a deeper understanding of people’s everyday life in a developing city.  相似文献

In the late medieval period the religious guilds along with trade guilds grew in importance, as did the role of material culture related to the guilds. This history has seen little examination from a Fenno-Scandinavian and particularly a Swedish vantage point. In order to analyse the role of material culture in the formation of this way of organizing people, the article investigates the existence of late medieval guildhalls, especially rural ones, and discusses remains of other material culture that can be connected to the guilds. The halls, drinking vessels and other material things were activated in the growth of a new more substantial way of organizing society outside the boundaries of feudal society and family control. It is argued that material culture had a significant role in the recurrent activities of the guilds of the Middle Ages and in the shaping of new ways of organizing people.  相似文献
