Osteoarthritis in a Black Death cemetery in London

Age-specific prevalence rates were determined in a group of skeletons recovered from a Black Death plague pit in London. The disease showed the expected increase in prevalence with age but these rates were lower than those in the contemporary population and the disease was more frequent in men than in women. In the majority of cases the disease affected one joint only and there were no cases of generalized osteoarthritis. The sites most commonly affected were the facet joints of the spine, the acromioclavicular joint and the hands; there were relatively few cases in which the large joints were affected but the knee was slightly more frequently affected than the hip.     

Rates for the job. Measures of disease frequency in palaeopathology

Measures of disease frequency are discussed and their use in palaeopathology illustrated with examples, both hypothetical and real. It is shown that prevalence rates are the appropriate rates to use when calculating the frequency of diseases in skeletal populations. The extent to which prevalence rates accurately reflect those in the living population from which the skeletons were derived is also considered and it is suggested that they are a reasonable approximation for diseases that do not shorten life span, but not for those that do. Finally, suggestions are made for dealing with missing data.     

Inter-observer variation in coding osteoarthritis in human skeletal remains

Thirty-eight participants at the VIIIth European Meeting of the Paleopathology Association took part in a study of inter-observer variation in scoring osteoarthritis in human skeletal remains. Ten specimens representing different joints were used and five criteria of osteoarthritis were scored. Eleven of the 38 participants ranked themselves as beginners, 13 as experienced and six as very experienced; the data were subsequently examined using the results from these 30, comparing beginners with experts. Agreement as to whether or not changes were present on the specimens and on the degree of change was seldom complete but was greater when scoring eburnation and the presence of new bone on the joint surface than for the three other criteria. There was little difference between beginners and experts. Although all the specimens were chosen to meet our published criteria for osteoarthritis, the experts were unanimous is agreeing the diagnosis in only three cases and the beginners in only one. These results suggest that more work needs to be done to develop operational definitions for the classification of disease in palaeopathology and that great care must be taken when comparing disease frequencies between studies.     

Clearances and Clearings: Deforestation in Mesolithic/Neolithic Britain

Clearances, interpreted from pollen records during the Mesolithic and Neolithic of Europe, are generally ascribed to purposive deforestation which is compatible with the transition model, whereby early Neolithic economic strategies are a development of late Mesolithic intensification of wild plant food husbandry. This paper considers the role of natural processes in creating clearings and the role of inadvertent impact of human activity on forest processes, including woodland regeneration. The role of climate, wind-throw and lightning strikes in creating clearings and forest instability is emphasised and the evidence discussed from sites which may be interpreted as resulting from opportunistic human use of natural clearings. Unfortunately, regional pollen diagrams lack sufficient spatial resolution to detect the size of isolated clearings or establish the spatial variation in forest composition that was intimately related both to forest ecology and the effects of subtle human impacts. This may be the major reason for an apparent contradiction between pollen evidence of Neolithic impact and the archaeological record. Moreover, early Neolithic agricultural activity may have been concentrated in valley bottoms, which is undetectable in regional pollen diagrams. Alternative models need to be considered, which include culturally specific exploitation of the local environment, along with the inadvertent ecological repercussions of pre-agricultural and early-agricultural human activities in naturally dynamic woodlands.     

Community-based development, non-governmental organizations and social capital in post-apartheid South Africa

Community-based development strategies are gaining in credibility and acceptance in development circles internationally and notably in post-apartheid South Africa. In parallel, the concept of social capital and the role of supportive nongovernmental organizations are receiving attention as key catalytic elements in encouraging and assisting community-based initiatives. In this paper, a well-documented initiative, the Hertzog Agricultural Co-operative in Eastern Cape province, is re-examined after the passage of several years to assess the impact of social capital and the involvement of a particular non-governmental organization in ensuring the sustainability and economic survival of the project. While both elements have proved critical to the project's life-cycle, particularly in recent years, concerns over possible dependency and project sustainability exist.     

World Class Aspirations,Urban Informality,and Poverty Politics: A North–South Comparison

Under the influence of the discourses and practices of global neoliberal urbanism, municipal administrations worldwide aspire to make their cities world class spaces, where informality is an anachronism and poverty can be made history. In this essay, drawing on fieldwork conducted in Jakarta, Indonesia, San Francisco (California), and Seattle (Washington), we address the question of how a geographic relational poverty approach can help us understand, or at least expand ways of thinking about these processes by attending to urban informality and the politics of poverty. Informality, a pervasive feature of the global South and North, functions as a survival strategy whereby the monetarily poor can compensate for their lack of income through commoning. Market-driven, state underwritten urban development initiatives for housing those with wealth is limiting the conditions of possibility for the monetarily poor, and informality. This is compounded by emergent political discourses rendering informality as inappropriate, and the monetarily poor as undeserving of a right to the city. Yet long-standing more-than-capitalist and communal informal practices pursued by the urban poor remain effective and necessary survival strategies, supporting residents whose presence is necessary to the city and whose practices challenge capitalist norms.
