Comparing the survival of osteocalcin and mtDNA in archaeological bone from four European sites

The small mineral-binding bone protein, osteocalcin, has been applied in a number of studies on ancient bone due to predictions of its long-term stability. However, the intact protein has not been shown to survive in ancient bone devoid of DNA, which is a much more phylogenetically informative biomolecule. In this investigation, the survival of osteocalcin is directly compared to the amplification of mtDNA in a set of 34 archaeological samples from four sites throughout Europe. We also present unpublished osteocalcin sequences of seven mammalian species in addition to the 19 published sequences to highlight phylogenetic limitations of this protein. The results indicate that the intact osteocalcin molecule survives less in archaeological samples than mtDNA and is more subject to the temperature of the archaeological site. Amino acid analyses show the persistence of the dominant protein collagen in samples that failed both osteocalcin and mtDNA analyses. The implications these findings present for biomolecular species identification in archaeological and palaeontological material are that, although proteins do survive beyond ancient DNA, osteocalcin does not appear to be the most ideal target.     

Gender Blindness and the Annulment of the Development Contract

This contribution to the Forum Debate responds to Horner and Hulme's analysis on the ‘rise of the South’, which they see as suggesting a dramatic redrawing of the global map of development and inequality. This response presents a critical South feminist perspective, informed by the lived realities of women in the South. It is based on a historical and political perspective that goes beyond income inequality to understand gender inequality in development within the persistent North–South divide.     

Luxury and Consumption in Eighteenth-Century Italy: Intellectual History,Methodological Ideas and Interdisciplinary Research Practice

Summary

This article has two aims. In the first part I will present some methodological considerations on intellectual history, particularly in relation to other disciplines considered similar yet different, such as the history of ideas, the history of concepts and the history of discourse. I will then seek to clarify what it means, in terms of research practice, to write intellectual history, taking as a starting point the subject of my own research, namely the political implications of economic thinking on luxury and consumption in Italy during the second half of the eighteenth century. More specifically, I intend to highlight the unique characteristics of intellectual history, understood as global history, which requires the reconstruction of the different contexts in which its underlying ideas and objectives developed, concentrating on its highly interdisciplinary nature. In particular, I will focus on a specific type of interdisciplinarity that characterised the methodology of my research, namely the attempt to hold together political thought and economic analysis. Eighteenth-century Italy was in fact marked by a strong, multifaceted political evaluation of economic thinking on luxury and consumption, which led me to examine the discussion of the subject through two lenses, those of economic analysis and political thinking. This specificity shows how the reconstruction of economic thought constitutes a fertile course for the investigation of the political culture and social projects of Italian authors in the eighteenth century, at a time when economic science was taking shape as a separate discipline.
