Insights into the processes behind the contamination of degraded human teeth and bone samples with exogenous sources of DNA

A principal problem facing human DNA studies that use old and degraded remains is contamination from other sources of human DNA. In this study we have attempted to contaminate deliberately bones and teeth sampled from a medieval collection excavated in Trondheim, Norway, in order to investigate this poorly understood phenomenon. Five pairs of teeth and bone samples were bathed in water containing various concentrations (from 10⁻⁹ and 10⁻²¹ g/l) of purified ΦX174 DNA. Subsequently the samples were subjected to a routine decontamination protocol involving a bleach bath followed by exposure to λ=254 nm ultraviolet light, prior to DNA extraction and analysis for evidence of the persistence of the contaminant. The results support previous speculation that bone is more susceptible to water‐borne sources of contaminant DNA, although both bone and teeth are readily contaminated and are difficult to decontaminate using the tested protocol. We believe that this is largely due to the porous nature of bone and teeth facilitating the deep penetration of the contaminant DNA. To simulate a more realistic handling situation, 27 further teeth were directly handled and washed, then decontaminated, prior to assaying for the residual presence of the handler's DNA. Surprisingly, although our results suggest that a large proportion of the teeth were contaminated with multiple sources of human DNA prior to our investigation, we were unable to contaminate the samples with further human DNA. One potential explanation may be the deposition of sediment or other structural changes that occur within the samples as they desiccate post‐excavation, which may protect samples from subsequent contamination, but also prevent the efficacy of bleach baths in decontaminating specimens.

Labour in Global Value Chains: Work Conditions in Football Manufacturing in China,India and Pakistan

A critical challenge facing developing country producers is to meet international labour standards and codes of conduct in order to engage in global value chains. Evidence of gains for workers from compliance with such standards and codes remains limited and patchy. This article focuses on the global football industry, a sector dominated by leading global brands that manage dispersed global value chains. It assesses the working conditions for football stitchers engaged in different forms of work organization, factories, stitching centres and home‐based settings in Pakistan, India and China. It draws on detailed qualitative primary field research with football‐stitching workers and producers in these three countries. The article explains how and why work conditions of football stitchers differ across these locations through an analytical framework that interweaves both global and local production contexts that influence work conditions. In doing so, it argues that current debates on the role of labour in global value chains have to go beyond a narrow focus on labour standards and corporate social responsibility compliance and engage with economic, technological and social upgrading as factors that could generate sustained improvements in real wages and workers’ conditions.     

Rehabilitating feminist politics and political theatre: Hélène Cixous's La Ville parjure ou le réveil des Erinyes at the Théâtre du Soleil

Hélène Cixous's 1994 play La Ville parjure ou le réveil des Erinyes , first produced at Ariane Mnouchkine's Théâtre du Soleil , insists on both theatre and feminism as valuable political practices in the face of the AIDS pandemic. Disguised in the trappings of Greek tragedy, the play reframes the scandal over the French government's complicity in the distribution of blood contaminated with HIV. As the mother of two young plague victims openly exhorts the audience to take part in righting social wrong, the Furies wreak havoc on the on-stage regime that ignores its citizens suffering. Ultimately the emphasis is not on peaceful resolution but on the critical need for action on social issues. The maternal heroine and strong women figures in this elaborate production insist on the impossibility of divorcing aesthetic considerations of theatre from its responsibility to create public awareness.     

The People,the Power and the Public Service: Political Identification during Guinea's General Strikes in 2007

In francophone West Africa, the term fonctionnaire unambiguously identifies public servants as integral parts of the state apparatus. Yet during general strikes in Guinea in 2006/7 this self‐evident association was called into question by the polarization of the public discourse which forced Guineans into associating either with the state or with the protesting people. Based on empirical data from ethnographic fieldwork, this contribution explores how public servants negotiated this tension during and after the upheavals. Their professional (historic) trajectories are constituted by ideological and institutional characteristics of post‐colonial state building and are fundamental for the participation of public servants in the changing dynamics of the local political arena. At the same time, these trajectories play an important and pertinent role in the everyday production of state that stabilizes society even during governance crises such as those experienced in Guinea.     

Practical and Auspicious: Thai Handbook Knowledge for Agriculture and the Environment

This article is the first thorough examination of the Thai handbooks that are produced to explain agricultural and environmental knowledge. These khu-meu (handbooks) and tamra (textbooks) come into use when knowledge is moving from one party to another. They also establish symbolic correlations within the human, terrestrial world, or between the human, terrestrial world and the worlds of the gods, spirits, ancestors, or the unseen. Despite the fact that handbooks are pervasive for the organising, preserving, retrieving, transmitting and consuming of knowledge throughout the Southeast Asian region, there has been very little concerted study of handbook knowledge. Our analysis of environmental handbooks in Thailand shows that simplified mastery is a common goal of the handbook genre in both its “how to” and “reading signs” forms. The knowledge captured by the Thai language handbooks is of a practical, predictive kind and suited to particular circumstances. Such knowledge can ultimately bridge and blur the dichotomy between scientific and local epistemologies.     

Poverty in Depth: a New Dialogue

This reflective piece draws together the themes and issues presented within the volume, exploring historic and contemporary definitions and attitudes towards poverty and their implications of the archaeological study of “slum” neighborhoods. It compares and contrasts the individual case studies from York and Manchester with investigations in America and Australia, drawing attention to the differences between them. Suggestions are made for future investigations, particularly in the potential for further comparative work at an international level.     

Intellectuals,nationalism, and the arts

In this article we argue that the role of intellectuals was essential (1) in the formation of Finnish cultural policy and (2) for the development of national cultural administration and public arts subsidy system in the country in the period leading up to the Second World War. The actions of the intellectuals can be considered as political choices in a contingent socio‐political realm, and arts as an essential part of the signifying system. In Finland, intellectuals remained active in the intertwining areas between the state and civil society. We highlight the impact of their actions especially through a study of archival materials obtained from the State Arts Boards. At these Boards, the intellectuals served as representatives of their own fields of arts in general, and of certain professional and civic associations and societies in particular. These intellectuals acted in various roles depending on the subject matter at hand, and as a result the decisions made by the boards reflected predominantly the interests of some groups over those of others.
