Abstract: Re‐reading the economic landscape of the western world as a largely non‐capitalist landscape composed of economic plurality, this paper demonstrates how economic relations in contemporary western society are often embedded in non‐commodified practices such as mutual aid, reciprocity, co‐operation and inclusion. By highlighting how the long‐overlooked lived practices in the contemporary world of production, consumption and exchange are heavily grounded in the very types and essences of non‐capitalist economic relations that have long been proposed by anarchistic visions of employment and organization, this paper displays that such visions are far from utopian: they are embedded firmly in the present. Through focusing on the pervasive nature of heterodox economic spaces in the UK in particular, some ideas about how to develop an anarchist future of work and organization will be proposed. The outcome is to begin to engage in the demonstrative construction of a future based on mutualism and autonomous modes of organization and representation.  相似文献

Organic fertilizers have the capacity to alter the nitrogen isotopic composition of plants. Camelid dung and seabird guano are two potentially important fertilizers in the agricultural systems of western South America, particularly Peru and Chile. This paper presents isotopic data (δ13C and δ15N) from field grown plants (maize, Zea mays) fertilized with the following four treatments: CO (control, no fertilizer applied), AS (ammonium sulfate, a chemical fertilizer), DU (camelid dung), and SG (seabird guano). Plants were grown in experimental plots in the Virú Valley, northern Peru. Plants fertilized with the chemical fertilizer presented very similar isotopic compositions compared to the control. Conversely, the camelid dung fertilized plants were characterized by higher δ15N values compared to the control plants (by 1.8 to 4.2‰ depending on the plant part). The seabird guano fertilized plants were greatly enriched in 15N in comparison to the control plants (by 11.3 to 20.0‰). The results of this study have important implications for the reconstruction of human diet using isotopic data derived from bone collagen and related tissues, particularly in the prehispanic Andes, but also in Europe and North America during the 19th century, when Peruvian seabird guano was used extensively. Specifically, the interpretation of the relative contributions of plant and animal protein to the diet on the basis of bulk isotopic compositions of bone collagen (or similar tissues) may be confounded by camelid dung fertilization if the carbon isotopic compositions of the two sources are similar. Likewise, the interpretation of the relative contributions of maize and marine protein may be confounded by seabird guano fertilization.  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

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
