Abstract:  In recent decades, welfare reform in the USA has increasingly been based on a political imperative to reduce the number of people on welfare. This has in large part taken place through the establishment of a "workfare" state, in which the receipt of state benefits requires a paid labor input. Designed to reduce expenditure on civil social services, welfare-to-work programs have been introduced. At the same time, the restructuring of US defense provision has seen the "military–industrial complex" emerge as a key beneficiary of state expenditure. Both of these trends can be characterized, this paper argues, as manifestations of neoliberal thinking—whether in the form of the "workfarism" that is undertaken to bolster the US economy, or the "defense transformation" that has been intended to enhance US war-making capacity. While these two aspects have been analyzed in detail independently, the aim of this paper is to probe the similarities, connections and overlaps between the workfare state and the recent American emphasis on high-technology warfare—the so-called "Revolution in Military Affairs"—and "defense transformation". There are, the paper argues, strong homologies to be drawn between the restructuring of the American defense and welfare infrastructures. Furthermore there are also instances where warfare and welfare are being melded together into a hybrid form "workfare–warfare", in which military service is increasingly positioned as a means of gaining welfare and, conversely, traditionally military industries are becoming involved in the area of welfare provision. The result, it is argued, is an emergent form of workfare–warfare state in the USA.  相似文献

Abstract: This article explores the value of Deleuzoguattarian approaches for understanding the entangled relationships between globalization, climate change, capitalism and indigenous peoples. Drawing on Brett Neilson's concept of wild globalization, it analyzes the biopolitics of climate change and capitalism as they are experienced on Nicaragua's Mosquito Coast. A focus on the heterogeneous economies and ecologies of the Miskito Keys and their destruction by Hurricane Felix reveals the destabilizing forces immanent to capitalism itself. Thinking about climate change not as a transcendent teleological megahazard, but as a Body without Organs, might enable us to be schizophrenic rather than paranoid about climate change.  相似文献

After plans for a potential partnership with Rio Tinto fell apart, the World Archaeological Congress applied for funds from the transnational mining corporation for the purpose of developing a policy on external engagement. This cautionary tale recounts the work that took place in 2007?C2008 as part of this project, some of the discussions that ensued, and a turn of events that delayed the ongoing process. In this paper the draft ??Principles to Guide External Engagement?? and ??Outline of a Process for Engagement?? (Appendices) are presented in the context of their formation, with an open call for further comment and discussion.  相似文献

Foraging ranges, migrations, and travel among Middle Holocene hunter–gatherers in the Baikal region of Siberia are examined based on carbon and nitrogen stable isotope signatures obtained from 350 human and 203 faunal bone samples. The human materials represent Early Neolithic (8000–6800 cal BP), Late Neolithic (6000–5000 cal BP), and Early Bronze Age periods (∼5000–4000 cal BP) and come from the following four smaller areas of the broader region: the Angara and upper Lena valleys, Little Sea of Baikal’s northwest coast, and southwest Baikal. Forager diets from each area occupy their own distinct position within the stable isotope spectrum. This suggests that foraging ranges were not as large as expected given the distances involved and the lack of geographic obstacles between the micro-regions. All examined individuals followed a similar subsistence strategy: harvesting game and local fishes, and on Lake Baikal also the seal, and to a more limited extent, plant foods. Although well established in their home areas, exchange networks with the other micro-regions appear asymmetrical both in time and direction: more travel and contacts between some micro-regions and less between others. The Angara valley seems to be the only area with the possibility of a temporal change in the foraging strategy from more fishing during the Early Neolithic to more ungulate hunting during the Late Neolithic–Early Bronze Age. However, the shift in stable isotope values suggesting this change can be viewed also as evidence of climate change affecting primary productivity of the Baikal–Angara freshwater system.  相似文献

Interpretations of dog burials made by ancient foraging groups have tended to be based upon our own relationships with such animals and modern western cosmological and ontological concepts. Osteological studies of early dogs often focus only on issues of taxonomy, and as a result very little is known about these animals’ life histories. Eastern Siberia has produced many Holocene dog burials, but these are typically not well described and the explanatory frameworks provided for them are very underdeveloped. Here we examine in detail two Cis-Baikal canid burials, one of a wolf and the other a dog, both in large Middle Holocene hunter-gatherer cemeteries. We link the mortuary treatment of these animals to other cultural practices, particularly the treatment of the human dead, and broader patterns in Northern human-animal relationships. This interpretive model is combined with detailed osteobiographies for the canids and contextual information for these and other dogs and wolves from Middle Holocene Cis-Baikal. It is argued that canids here were understood and treated in a variety of ways. We suggest that some animals with unique histories were known as distinct persons with ‘souls’ and because of this at death required mortuary rites similar to those of their human counterparts.  相似文献

Archaeological fish bones reveal increases in marine fish utilisation in Northern and Western Europe beginning in the 10th and 11th centuries AD. We use stable isotope signatures from 300 archaeological cod (Gadus morhua) bones to determine whether this sea fishing revolution resulted from increased local fishing or the introduction of preserved fish transported from distant waters such as Arctic Norway, Iceland and/or the Northern Isles of Scotland (Orkney and Shetland). Results from 12 settlements in England and Flanders (Belgium) indicate that catches were initially local. Between the 9th and 12th centuries most bones represented fish from the southern North Sea. Conversely, by the 13th to 14th centuries demand was increasingly met through long distance transport – signalling the onset of the globalisation of commercial fisheries and suggesting that cities such as London quickly outgrew the capacity of local fish supplies.  相似文献

This paper presents the results of a project aimed at investigating the deterioration of organic remains at the Mesolithic site of Star Carr. Analyses of pH, Electrical Conductivity and Redox Potential are reported from borehole transects across the unexcavated part of the site. A comparison of field and laboratory measurements is made, leading to the characterisation of different preservation zones and identification of ‘vulnerable’ sediments at the site. These data are augmented by geochemical analyses of contemporary borehole sequences and adjacent historic monoliths. Analysis of surface water and groundwater has also been undertaken to assist in the interpretation of the site hydrology and geochemistry. The relationship between ‘natural’ geology and preservation potential, and the evidence for a ‘halo’ preservation effect in virgin sediments adjacent to previous archaeology trenches is investigated.  相似文献
