Internal oxidation of cast iron artifacts from an 18th-century steel cementation furnace

Heavily corroded metal artifacts recovered from the site of an 18th-century steel cementation furnace in Trenton, New Jersey, are cast iron altered by internal oxidation. The progress of the internal oxidation process was followed by comparison with the microstructure of cast iron exposed to high temperature in a wood-burning fireplace. The graphite flake structure of the cast iron allows deep, rapid penetration of oxygen that reacts at the iron–carbon interfaces within the iron to form iron oxides that eventually replace the graphite flakes. Microprobe analyses show that the silicon in the cast iron is converted to knebelite that also serves as the host for phosphorus. Sulfur dispersed in the internal oxidation product and porosity appear to be responsible for rapid rusting of the artifacts. Internal nitriding accompanies the oxidation. The Trenton artifacts are interpreted as grate bars from the fire box of a cementation furnace.     

The Pervasive Nature of Heterodox Economic Spaces at a Time of Neoliberal Crisis: Towards a “Postneoliberal” Anarchist Future

Abstract: Re‐reading the economic landscape of the western world as a largely non‐capitalist landscape composed of economic plurality, this paper demonstrates how economic relations in contemporary western society are often embedded in non‐commodified practices such as mutual aid, reciprocity, co‐operation and inclusion. By highlighting how the long‐overlooked lived practices in the contemporary world of production, consumption and exchange are heavily grounded in the very types and essences of non‐capitalist economic relations that have long been proposed by anarchistic visions of employment and organization, this paper displays that such visions are far from utopian: they are embedded firmly in the present. Through focusing on the pervasive nature of heterodox economic spaces in the UK in particular, some ideas about how to develop an anarchist future of work and organization will be proposed. The outcome is to begin to engage in the demonstrative construction of a future based on mutualism and autonomous modes of organization and representation.     

Revamping community‐based conservation through participatory research

Community‐based conservation is experiencing a crisis of identity and purpose as a result of a disappointing track record and unresolved deficiencies. The latter include over‐simplified assumptions and misconceptions of “community,” the imposition of externally designed and driven projects at the community level, a focus on conservation outcomes at the expense of community empowerment and social justice, and limited attention to participatory processes. New approaches are urgently needed to address these weaknesses and to counter a rising trend towards environmental protectionism and a preference for conservation approaches at an eco‐regional scale that threaten the interests of local and Indigenous communities. We propose that three core principles of community‐based participatory research (CBPR)—(1) community‐defined research agenda; (2) collaborative research process; and (3) meaningful research outcomes—hold much promise. Drawing on the experience of a research partnership involving the James Bay Cree community of Wemindji, northern Quebec, and academic researchers from four Canadian universities, we document the process of applying these principles to a community‐based conservation project that uses protected areas as a political strategy to redefine relations with governments in terms of a shared responsibility to care for land and sea. We suggest that basic assumptions of CBPR, including collaborative, equitable partnerships in all phases of the research, promotion of co‐learning and capacity building among all partners, emphasis on local relevance, and commitment to long‐term engagement, can provide the basis for a revamped phase of community‐based conservation that supports environmental protection while strengthening local institutions, building capacity, and contributing to cultural survival.     

ASSESSING THE REGIONAL IMPACT OF GRANTS ON FDI LOCATION: EVIDENCE FROM U.K. REGIONAL POLICY, 1985–2005

ABSTRACT The paper implements a methodology for assessing the regional impact of investment grants on foreign direct investment (FDI) location, taking data for U.K. regional policy over the period 1985–2005. Using a Generalized Methods of Moments estimator it finds that each £25 million of grant changes the regional location of about six inward FDI projects. On average, projects have 150 jobs and each job diverted costs £27,500 (1995 prices). It also finds that the size of the area designated for grants has a positive location effect. The effect is small in relation to the overall scale of FDI, which may explain the weak grant effect found in recent plant‐based location studies.     

Interpreting the expansion of sea fishing in medieval Europe using stable isotope analysis of archaeological cod bones

Archaeological fish bones reveal increases in marine fish utilisation in Northern and Western Europe beginning in the 10th and 11th centuries AD. We use stable isotope signatures from 300 archaeological cod (Gadus morhua) bones to determine whether this sea fishing revolution resulted from increased local fishing or the introduction of preserved fish transported from distant waters such as Arctic Norway, Iceland and/or the Northern Isles of Scotland (Orkney and Shetland). Results from 12 settlements in England and Flanders (Belgium) indicate that catches were initially local. Between the 9th and 12th centuries most bones represented fish from the southern North Sea. Conversely, by the 13th to 14th centuries demand was increasingly met through long distance transport – signalling the onset of the globalisation of commercial fisheries and suggesting that cities such as London quickly outgrew the capacity of local fish supplies.

Mundane Myths: Heritage and the Politics of the Photographic Cliché

This paper considers the impact of photographic clichés on the management, conceptualization, and experience of heritage. Working along the grain of pejorative readings of ‘snapshot’ photography, this account views the repetitiveness and redundancy of the cliché as a critical point of departure, rather than a cause for reproach. Taking the World Heritage Site of Angkor as a core case study, three intersecting axes of political concern are sketched out to elucidate the broad social, material, and affective implications of clichéd photography for heritage. First, processes of dehistoricization and depoliticization are interrogated in relation to the role certain images play in constructing a mythic sense of the past in the present. This leads directly in to the second strand of analysis, which examines the various ways in which individuals negotiate these myths through the production of their own highly personalized photographic clichés. Here I develop the concept of an embodied politics of heritage photography to grasp the multivalent resonances of tourist clichés in particular. Finally, the implicit and explicit forms of spatial control that permeate sites such as Angkor are examined in relation to the photographic clichés they respond to and help shape.
