Economic geography under postcolonial scrutiny

Because the economy is not found as an empirical object among other worldly things, in order for it to be 'seen' by the human perceptual apparatus it has to undergo a process, crucial for science, of representational mapping. This is doubling, but with a difference; the map shifts the point of view so that viewers can see the whole as if from the outside, in a way that allows them, from a specific position inside, to find their bearings.

Biopower, genetics and livestock breeding: (re)constituting animal populations and heterogeneous biosocial collectivities

Genetic techniques have become increasingly prevalent in livestock breeding, associated with new types of knowledge-practice and changes in the institutional and geographical relationships related to animal husbandry. This paper examines the value of Foucault's concept of 'biopower' to theorising livestock breeding and the implications of the rise of genetic knowledge-practices in agriculture, developing the concept to apply to nonhuman animals and to situations where humans and nonhuman animals are co-constituted through particular knowledge-practices and corporeal meetings. It focuses on the idea of 'population' as a central component of biopower, and relates this to conceptualisations of biosocial collectivity. Reacting to the inherent humanism of Foucault's outlining of biopower, the paper argues for its relevance in relation to nonhuman populations, and for heterogeneous conceptualisations of biosocial collectivity. Drawing on research with UK beef cattle and sheep breed societies, the paper explores how, in practice, populations are constructed in relation to the production of particular sorts of truths concerning, and particular modes of intervention in, the lives of nonhuman animals. It explores how heterogeneous biosocial collectivities are constituted around these interventions. The emergence of genetic techniques is shown to transform the processes constituting populations and heterogeneous biosocial collectivities, and this is discussed in terms of a new inflection of agricultural biopower associated with novel interventions in the lives of livestock animals.     

Towards the application of desorption electrospray ionisation mass spectrometry (DESI-MS) to the analysis of ancient proteins from artefacts

The detection and identification of protein residues from archaeological artefacts has been the subject of considerable controversy over the past two decades, this controversy spurring the application of a range of different analytical methods. Part of the debate surrounds the ability of the methods to uniquely identify original proteins. Another is the apparent contradiction between the ease of extraction in the laboratory of residues that have managed to survive in sediment over millennia; some studies use simple solvents including water, whilst others claim that efficient extraction requires the destruction of the artefact.Desorption electrospray ionisation mass spectrometry (DESI-MS) offers the potential to directly analyse proteins bound to the surface of artefacts. The method permits desorption of analytes under ambient conditions directly from a wide range of surfaces with little or no sample preparation. This has already led to its application in a range of areas, including forensic analysis of trace levels of narcotic drugs. It does not require destruction of the artefact (e.g. by drilling or dissolution) and can work in concert with other methods (for instance it could be used as a screening tool prior to lipid extraction).Here we report the construction of a DESI-MS interface and consider the potential of the method to contribute to the debate surrounding the preservation of proteins on artefacts. The DESI-MS interface was fitted to a conventional ion trap mass spectrometer and tested using peptides and proteins artificially applied to the surface of flint flakes and potsherd samples. A range of intact proteins was analysed; the DESI interface identified test proteins up to a maximum molecular weight of approximately 20 kDa. Peptides generated from these and larger proteins could be detected using DESI-MS following tryptic digestion in situ. The collected data allowed identification of the originating proteins. The potential applications to archaeological science of this new analytical tool are discussed.     

‘The Dining Room Should Be the Man's Paradise,as the Drawing Room Is the Woman's’: Gender and Middle‐Class Domestic Space in England, 1850–1910

In the middle‐class home in late nineteenth‐century England, drawing rooms, morning rooms and boudoirs became increasingly associated with women, while dining rooms, studies and smoking rooms were viewed as male spaces. Historians have linked this to the exclusion of women from social power and a male ‘flight from domesticity’. This article questions these interpretations and explores gendered space through advice manuals, inventories and sale catalogues, and autobiographies. While the notion that domestic space should be divided between men and women had considerable cultural purchase, the ways in which this should occur were subject to dispute and limited by the practical contingencies of everyday living. In homes where gendered material culture was present, it exerted a powerful influence on childhood experience and the formation of adult identities.     

pXRF: a study of inter-instrument performance

Integrating portable X-ray fluorescence (pXRF) instrumentation into archaeological investigations has generated as much interest as skepticism because several characteristics of the technique limit analytical accuracy and precision. This paper seeks to explore inter-instrument performance in order to assess the potential pXRF instrumentation has in examining the elemental composition of lithic raw materials. Two pXRF instruments, Delta and Omega models both manufactured by Olympus Innov-X Systems, were utilized to obtain the trace element signatures of five fine-grained volcanic sources and four obsidian sources in the Great Basin. We compared the two portable instruments to a wavelength-dispersive instrument extensively calibrated with geologic standards and to a commercial benchtop energy-dispersive system. Our results suggest that the relationships between the data produced by these different instruments are complex, and as we look to the future of pXRF use in archaeological analysis we argue that that the same strict protocols applied in laboratory-based XRF analyses, involving instrument calibration, evaluation of inter-instrument performance, and comparison to accepted geologic standards, need to be applied in pXRF analysis.     

Geographies of Isolation: How Workers (Don’t) Access Support for Problems at Work

Abstract: This paper is concerned with the social and spatial processes adopted by workers who face problems at work. Using interview data with minority ethnic workers in three local communities in London, the paper explores the mechanism people use to seek help and advice and what resources are available from local community organisations. Key findings suggest that many workers, both unionised and non‐unionised find themselves isolated and unable to access the support they need.     

Environmental context of a Neolithic site at Beifudi,north-west Hebei Province,China

The earliest evidence of prehistoric religious practice in China found so far comes from excavations at Beifudi, about 120 km south of Beijing, in the form of votive offerings and porcelain sorcery masks dated to the period 8000–7000 yr BP. These finds are part of a rich Neolithic site located on the second river terrace on the north shore of the Yi River. This paper presents results of pollen analysis of part of a sediment profile from a depression at the edge of first terrace towards second terrace, a few hundred metres away from the main archaeological finds. A sequence of marked changes in environment occurred between 9000 cal yr BP and 6000 cal yr BP, and dating evidence suggests strong associations with the ebb and flow of human activity in the area. The first phase of activity on the site begins at around 8000 cal yr BP, towards the end of a period of relatively dry, cold environmental conditions. Between 7800 cal yr BP and 7400 cal yr BP, the first clear evidence of cereal cultivation appears in the pollen record. Rich archaeological finds occur during the same time period, suggesting local prosperity. This first phase of the Beifudi culture ends at 7300 cal yr BP, when warmer and wetter conditions are inferred and wetland areas expand, reducing the area available for crop cultivation near the site. A return to drier and cooler conditions from 6900 cal yr BP corresponds with the second phase of apparent prosperity in the archaeological record from Beifudi. This phase ends at around 6500 cal yr BP, at the start of another shift towards wetter conditions in the flood plain environment. The pollen record suggests that environmental conditions in the flood plain were a major determinant of human activity at Beifudi in the early-mid Holocene.
