X-ray microtomographic imaging of charcoal

We assess the potential of X-ray microtomography as a tool for the non-destructive, three-dimensional examination of the internal structure of charcoal. Microtomographic analysis of a series of charcoals produced by the experimental pyrolysis of pine wood at temperatures from 300 and 600 °C in nitrogen only and in nitrogen mixed with 2% oxygen indicates that, despite substantial shrinkage, observed porosity, pore size and pore connectivity are all increased by pyrolysis and also by chemical oxidation. Analysis of a number of altered and unaltered archaeological and geological charcoals has demonstrated the capacity of the technique to identify and map the distribution of authigenic mineral contamination within charcoal fragments. The results are of significance to radiocarbon dating in that they provide insights into the mechanisms by which charcoal can be contaminated by extraneous carbon in the natural environment.     

Enrolling the Private Sector in Community Development: Magic Bullet or Sleight of Hand?

The role of the private sector in international development is growing, supported by new and evolving official programmes, financing, partnerships and narratives. This article examines the place of the private sector in ‘community development’ in the global South. It situates corporate community development (CCD) conceptually in long‐standing debates within critical development studies to consider the distinct roles that corporations are playing and how they are responding to the challenges and contradictions entailed within ‘community development’. Drawing on field‐based research across three different contexts and sectors for CCD in Fiji, Papua New Guinea and South Africa, the article suggests that caution is required in assuming that corporations can succeed where governments, non‐governmental organizations (NGOs) and international development organizations have so often met with complex challenges and intractable difficulties. We argue that four specific problems confront CCD: (a) the problematic ways in which ‘communities’ are defined, delineated and constructed; (b) the disconnected nature of many CCD initiatives, and lack of alignment and integration with local and national development planning policies and processes; (c) top‐down governance, and the absence or erosion of participatory processes and empowerment objectives; (d) the tendency towards highly conservative development visions.     

Archaeology, the Activist Community, and the Redistribution of Power in New York City

Two New York City projects, one world renown, the other struggling for recognition, exemplify the various ways in which the public defines its engagement with its archaeological past. At African Burial Ground in lower Manhattan and at Duffield Street in Brooklyn, the public battled with local, state, and federal entities in an effort to preserve the resources. As different as the sites are in context, scope and circumstances, public reactions and activism bind them together.     

New spaces of citizenship? Rethinking gendered participation and empowerment in South Africa

This paper draws on empirical research in South Africa to explore questions about the exclusionary nature of citizenship, the problems and possibilities of participatory citizenship and its potential reconceptualisation through the lens of gender. The paper examines some of the major debates and policies in South Africa around issues of citizenship, participation and gender and explores why the discursive accommodation of gender equity by the South African government is not fully realised in its attempts to construct substantive and participatory citizenship. It explores some of the emergent spaces of radical citizenship that marginalized groups and black women, in particular, are shaping in response. Findings suggest that whilst there are possibilities for creating alternative, more radical citizenship spaces, these can also be problematic and exclusionary. The paper draws on recent feminist writing to examine the possibilities for rethinking citizenship as an ethical, non-instrumental social status, distinct from both political participation and economic independence. This reframing of citizenship moves beyond notions of ‘impasse’ or ‘hollowness’, challenges the public/private distinction that still frames many debates about citizenship and considers the emancipatory potential of gendered subjectivity. The paper argues that citizenship is shaped by differing social, political and cultural contexts and this brings into sharp focus the problematic assumption of the universal applicability of western concepts and theories.
