Manifestations of Contradiction: Lakes within the Production/Consumption Dialectic

Much emphasis within Marxist political ecology has focused on the social production of nature. Less attention, however, has been paid to the ways in which an emergent, material nature is an actor in the dialectic of its own appropriation. This paper examines the attempt to capitalize, under simultaneous processes of production and consumption, two proximate yet different Minnesota lakes. Lakes Elysian and Frances represent biophysical nature as process. Yet, their contrasting apparent states of permanence emerge from their dynamic relationships with agriculture, further affecting residential construction on their shores and lake association politics. Information collected from lakes surveys conducted by the Minnesota Pollution Control Agency, Minnesota Department of Natural Resources and personal interviews with lakes association members provide insight into relational processes that influence the appearance of these lakes. Using this investigation, efforts can be made to resist discourses and practices that reify the existence of “green” lakes as inevitable. It is suggested, then, that a new politics of lakes management should be mediated that is less dependent upon their capitalization.     

Introducing a new experimental design for controlled studies of flake formation: results for exterior platform angle,platform depth,angle of blow,velocity, and force

Potential variables that underlie variation in flake size, and in some instances shape, are investigated in a newly designed experiment. This new design, which utilizes glass cores molded to a specific shape, results in flakes that are identical to archaeological ones. Variation in exterior platform angle, platform depth and angle of blow all directly affect flake size, and in the case of exterior platform angle, flake shape as well (in spite of constant core surface morphology). In treating velocity and force independently, neither is found to affect flake size or shape. These results have implications for understanding different strategies that flintknappers may employ to control the size of their flake products.     

Provenance of Coals Recovered from the Wreck of HMAV Bounty

Coal samples from HMAV Bounty were analysed using standard techniques to shed light on their provenance. Petrographic analysis indicated they were Carboniferous, with high vitrinite and liptinite content and a mean random reflectance of vitrinite of 0.99%. Palynological analysis indicated the samples were derived from the Middle Coal Measures, Westphalian B. Combining coal rank (vitrinite reflectance), age, knowledge of seam distributions and coalfield history indicates the most like source to be the Durham Coalfield, possibly the Hutton or Low Main Seams. These coals were mined along the valley of the Weir in the latter part of the 18th century.
