Estimating original flake mass from 3D scans of platform area

This study confirms the increased capacity to predict flake mass that arises from more accurately measuring surface area in three dimensions using a digital scanner. We also reveal the existence of significantly different relationships between platform area and flake mass for flakes with different platform types and ventral and dorsal morphologies. These different relationships between platform surface area and mass have not been previously identified, and reveal the complexity of platform/mass relationships. Using multivariate regression of 3D platform surface area and external platform angle we improve the accuracy of predictions of original flake mass. We propose a method for studying reduction intensity on retouched flakes, based on comparing predictions of the initial mass of the flake with measurements of the mass following retouching to estimate the amount of mass removed through retouching. We name this approach the Initial-/Terminal-Mass Comparison, or ITMC. Our experiments demonstrate that the capacity of the 3D platform scans to predict flake mass, and by implication the capacity of the ITMC to estimate mass loss, rivals or exceeds the capacity demonstrated for existing reduction measures.     

The Violence of Poverty: Theology and Activism in an “Age of Austerity”

ABSTRACT

Faith groups are in the front line of the struggle to defeat poverty in breadline Britain. Given their roots in local communities Churches and Christian NGOs are well-placed to challenge economic policies that have resulted in the spiraling of food poverty, homelessness, personal debt and child poverty. By framing poverty as a political choice, a form of structural violence and systemic sin this paper brings peace studies and political theology into a constructive dialogue. In the face of ongoing “austerity” the paper demonstrates that poverty represents a clear and present danger to the social fabric of the UK and argues that only a re-imagined interdisciplinary theology of liberation can provide academics and activists with the tools needed to defeat systemic poverty and the cultural violence upon which it rests.     

Peatland conservation in Buchan,north‐east Scotland: The historic context and contemporary issues

Scottish peatlands are now recognised as important habitats for conservation, and are increasingly protected by both national and international designations. This paper examines peatland conservation in north‐east Scotland, using recently published data to assess habitat quality, and relating this to longer‐term historical trends in attitudes towards peatlands, and their utilisation. The historical data indicates that peatland losses in northeast Scotland have been extensive, and occurred rapidly during the 18th and 19th centuries, when peatlands were regarded as fuel sources, or wastelands which could be converted to agricultural use. Threats have lessened in the second half of the 20th century, and many sites are now protected by conservation designations. However, historical attitudes towards peatlands often persist, and this can pose problems which must be addressed if conservation management is to be successful.     

Exploring Bristol’s historic glass industry: archaeological investigation at the Soap Boilers’ and Hoopers’ glasshouses,and the Powell & Ricketts’ Bottle Works,Avon Street,Glass Wharf,Bristol

SUMMARY: In 2007, extensive archaeological excavation was undertaken on an important post-medieval glassworking site at Glass Wharf, Bristol. The excavation exposed remains relating to a series of glassworks dating between the early 18th and early 20th centuries and, significantly, uncovered a sequence of five glass-melting furnaces and covering structures, which together reflect wider changes in glassmaking technology throughout these periods. Detailed scientific analysis of glassworking debris from the excavation has also been undertaken, which provides much-needed detail on the development of recipes and raw materials used in bottle manufacture during the 18th and 19th centuries.
