Manuring and stable nitrogen isotope ratios in cereals and pulses: towards a new archaeobotanical approach to the inference of land use and dietary practices

This paper explores the impact of animal manure application on the δ¹⁵N values of a broad range of crops (cereals and pulses), under a range of manuring levels/regimes and at a series of locations extending from northwest Europe to the eastern Mediterranean. We included both agricultural field experiments and areas where ‘traditional’ farming is practised. Our aim is to ground-truth interpretation of δ¹⁵N values in archaeobotanical crop remains as evidence of past growing conditions and husbandry practices. The results confirm the potentially radical impact of manuring on δ¹⁵N values in cereals, depending on manuring level, but indicate only a slight effect on pulses, which can fix atmospheric nitrogen. The expected geographical trend towards greater δ¹⁵N with increasing climatic aridity is not apparent, probably because the growing conditions for crops are ‘buffered’ through crop management. Each of these observations has fundamental implications for archaeobotanical interpretation of δ¹⁵N values as evidence of land use practices and (together with analysis of bone collagen/tooth enamel in potential consumers) palaeodiet.     

Lethal differences: a short history of the concepts of wealth and poverty in Danish epidemiological writings, 1858-1914

Through a study of the history of the concepts of wealth and poverty, this paper investigates the onset of a tradition in the conceptual architecture of epidemiological research concerning social differences in mortality rates from 1858 to 1914. It raises the question as to what the concepts of wealth and poverty meant to those who used them and what objects of interventions the conceptual architecture surrounding the concepts enabled the researchers to create. It argues that a transition began in the late 19th century in which an important framework for the understanding of causal relations behind the mortality patterns changed and that this change in turn influenced the scope of what was conceived as relevant objects of intervention.     

Building from Scratch: The aesthetics of post‐disaster reconstruction(Respond to this article at http://www.therai.org.uk/at/debate)

This article looks at the visual character of post‐conflict and post‐disaster settings, and shows how states of physical ruin can help to produce an ‘aesthetics of post‐disaster reconstruction’. With examples primarily drawn from the author's field site in Timor‐Leste, the article shows how ruins, ashes and demolition may be perceived as enabling particular kinds of agency and opportunity. Thus, some of the most hopeful of international‐intervention dreams of recent decades have been produced out of sites of mass‐scale destruction.     

Die Entwicklung der Sozialgeschichte der modernen Mathematik und Naturwissenschaft und die Frage nach dem sozialen Raum zwischen Disziplin und Wissenschaftler

The use of the concept of social history of science is sketched in the Anglo‐American and the German discussions from the mid 1970s up to recent work. By presenting a ‘social map’ of a selected scientific community it is argued that between the categories of discipline and single scientist there exists a wide ‘social space’ of groups within which science is pursued. In adopting a milieu theoretic approach an ecology of science is proposed as a suitable extension of the social history of science.
