For the Vula'a people of south‐eastern Papua New Guinea names are a way of knowing that is intimately linked to a particular mode of being. The ethnography of Vula'a naming practices presented here, and an analysis of their stories – traditionally known as rikwana – suggests that names are essential in the Heideggerian sense that they bring the past, present, and future into proximity and thus may be understood as a form of historicity. In certain contexts names are also powerful because they are implicated in the kinds of transformations commonly described by anthropologists as magical. Magical names link knowing and speaking with a vital aspect of Vula'a cosmo‐ontology known as iavu (heat).  相似文献

Although a tremendous amount of analytical research is being conducted on the hub location problem, few models exist that extend the number of characteristics found in actual hub-and-spoke networks. Four extensions are presented in this paper: (1) a capacitated network model; (2) a minimum threshold model; (3) a model that endogenously determines the number of open hubs for the network; and (4) a model that incorporates a flow-dependent cost function for the spokes as well as the interhub links. Both the capacitated and the minimum threshold models drop the assumption of a completely interconnected network commonly found in hub location models. Numerical results show that total network costs are often minimized by closing a few interhub links. The third extension is the first known hub location model to determine the optimal number of hubs based on the needs of the network. In this model, the number of open hubs depends on the distribution of flows in the network and how cost effectively the flows can be moved across the network. Previous models that endogenously determined the number of open hubs utilized a fixed cost for establishing each hub in order to limit the number of hubs in the network. The final extension recognizes the potential of all links to amalgamate flows and includes a separate flow-dependent cost function for the spokes in addition to the one for the interhub links. Numerical results are shown for all four models.  相似文献

Interfacility Interaction in Models of Hub and Spoke Networks   总被引:3,自引:0,他引:3  
Providers of transportation services may reduce their average unit costs by bundling flows and channeling them between hubs (also known as concentrators or routers). The resulting facility locations are interdependent because of the flows between them. This paper analyzes mathematical models of hub systems in an effort to enhance understanding of the optimal location of interactive facilities. The paper examines the behavior of solutions to several alternative models that require the location of a hub at either of two similar locations. A model employing a concave cost function favors the assembly of flows, penalizes fractional facility locations, and produces local minima that have integer facilities.  相似文献

Following the 2005 terrorist attacks on London it emerged that two of the terrorists charged with the failed 21st July bombings had arrived in the UK as child asylum seekers from East Africa. In the ensuing debate the bombers were represented as children that turned to hate. In this discussion paper we draw on empirical work conducted in Sheffield, UK to explore the identities, affiliations and practices of Somali asylum seeker children, aged 11–18.1 1This ongoing research is being funded by the ESRC Identities and Social Action Programme (Award No: RES-148-025-0028) View all notes Specifically, we argue that the actions of the two bombers need to be framed within a broader understanding of the complex processes of social identification that take place as young people negotiate what it means to be a child in the context of different ‘age’, gender and racialised expectations and against a backdrop of discrimination and social exclusion in different relational geographical spaces. We begin by outlining the context of UK immigration policy, before reflecting on dominant constructions of both childhood and asylum seekers. We then discuss how these may shape young refugee and asylum seekers' own narratives of the self and the role that their mobility and specific sites of identity formation may play in this process. In doing so, we contribute to children's geographies by addressing a group – refugee and asylum seekers – that has been neglected within the sub-discipline.  相似文献

For nearly four hundred years, Pueblo potters in the Rio Grande Valley of New Mexico produced technologically innovative glaze-decorated bowls and exchanged them widely among different villages. While potential sources of lead ores used to make glaze paints are found throughout the Rio Grande Valley region, researchers have only recently begun to identify which ore sources potters exploited and to understand the social and economic factors underlying patterns of ore resource use. In this paper we use stable lead isotope and electron microprobe analysis of glaze paints on Rio Grande Glaze Ware made at two Salinas pueblos to identify ore sources and glaze recipes used by their potters. Despite some isotopic overlap of ore sources, the lead isotope data point to regular exploitation of ores from the Socorro area of the southern Rio Grande. Salinas potters apparently used other sources as well, and likely mixed ores from different sources. We also identify four local glaze recipes that appear to incorporate multiple ore sources, suggesting that Salinas potters obtained raw ores rather than finished glaze paints.  相似文献

The decline of ‘universal’, welfarist forms of social citizenship and the rise of selective or targeted social policy is generally considered to be a recent phenomenon, and a constituent element of neo-liberal citizenship and state forms (Brodie ), or ‘advanced liberal’ technologies of government (Rose ). This paper documents how targeted policies were in fact being defined at the height of Keynesian welfarism, in the newly consolidating post-war suburbs of Toronto. I suggest an alternative account of the genesis of these practices, which sees the spatiality of the post-war metropolis as key. The analysis considers how the mutual consolidation of these social and material spaces, and of hegemonic suburban political practices enabled the articulation of a suburban style of citizenship, which was both intensely familial and entrepreneurial in form. Through a case study in recreation policy in the Toronto region, this paper demonstrates how selective, targeted and residual approaches to service delivery evolved in suburban municipalities in the immediate post-war period, and were only generalized across the city more recently through the restructuring of a municipal amalgamation. It documents how these approaches have relied on radically different assumptions about citizenship that were dependent on the articulation of suburban life, literally built around the private family in private space. Thus this paper also documents ways in which these approaches to social policy, increasingly dominant across a range of policy areas and at a variety of spatial scales, construct gendered and racialized identities and problematize non-nuclear family forms.  相似文献

Heritage organisations depend on public support, which presupposes a reputation for responsible custodianship, technical expertise, sound financial management and sensitivity to conflicting public expectations (e.g. conservation and public access). Public support, however, can be fickle; a reputation can be severely damaged in a few days as a result of an unexpected crisis. Heritage managers have traditionally adopted a reactive approach to crisis handling. Such approaches frequently give rise to panic-driven responses, which amplify the scale of the original crisis and lead to a breakdown of trust among stakeholders. Having explored some examples of crises in the management of the archaeological heritage, this paper concludes with a case for managers to develop proactive crisis-management strategies. The proposed framework recognises its symbiotic relationship with the disciplines of strategy and reputation management. It incorporates three key elements: the identification and evaluation of risks; procedural arrangements for operating in a disaster situation; and effective communications to ensure the continuing support of stakeholders.  相似文献
