Empire forestry and the origins of environmentalism

When and where did the environmental movement begin? To understand how a public endued with the principles of laissez-faire reversed in such short order a century-old policy of government land disposal, this paper examines how public ownership of land came to be celebrated, with a newly defined professional corps of government foresters such as Dietrich Brandis and Gifford Pinchot feted as popular heroes. Hard-headed environmentalists and legislators found in empire forestry a ready-made model to construct vast areas of the public domain as a utensil for not only environmental but state purposes—industrial, settlement, and budgetary. The empire forestry matrix of government reservations, fire protection, and revenue-enhancing forests solved the tension between romantic preservationist notions and laissez-faire ideals and gave the compromise from which modern environmentalism emerged: it posed environmental problems and solutions as a means to construct the state. This article traces the international trail of modern environmentalism from India, under Lord Dalhousie's forest charter, to the British colonies in Africa and Australasia where it matured, and finally to Canada, the United States and other parts of the globe where environmentalism permanently entered the pantheon of democratic political creeds.     

Learning to sail the Duyfken replica

The rig of the Duyfken 'replica', a reconstruction Dutch jacht of c . 1600 is described. Sail-handling techniques and sailing performance including steering with a whipstaff are also described. Experiments to improve sailing efficiency, some prompted by analysis of contemporary iconography, are discussed.     

Cross-cultural interaction on Wuvulu Island,Papua New Guinea: the perspective from use-wear and residue analyses of turtle bone artifacts

Recent studies have emphasized the importance of Indigenous producers and traders in the formation of ethnographic museum collections, but have found difficulty in finding concrete evidence for their active roles. A use-wear and residue study of turtle bone cleavers from Wuvulu Island, Papua New Guinea provides the opportunity to test whether objects that comprise a significant component of early collections were made specifically for sale, as hypothesized by contemporary observers in the late 19th century. Comparative studies of used and unused turtle bone artifacts from the Caroline Islands and Papua New Guinea identified differences between wear traces resulting from manufacture and use. Analyses of the Wuvulu turtle bone cleavers showed they had been heavily used prior to sale. Rather than produce artifacts to meet the high demand from German traders, the local people sold old, worn-out objects, many of which had been repaired. The study demonstrates that archaeological approaches to ethnographic museum collections can trace Indigenous agency within cross-cultural interaction. It also showcases the potential of use-wear and residue analytical techniques for the analysis of bone tools and the utility of digital, hand-held microscopes for the analysis of large artifacts.     

Multiplying Labour,Multiplying Resistance: Class Composition in Buenos Aires’ Clandestine Textile Workshops

Buenos Aires’ talleres clandestinos (clandestine textile workshops) are powerful sites of accumulation and resistance; a complex and communitarian migrant economy. The economy’s complexity is, however, masked by its spatiality, clandestinity, and the promotion of culturalist analyses that ignore intra-collective class differentials. This paper considers the “autonomy of migration” approach through the lens of “class composition” to explore the talleres’ contours. Witnessed in the talleres is a clear “multiplication of labour”, yet approaching this multiplication compositionally highlights the multiple examples of resistance and refusal immanent to the workshop economy. But this dialectic of control and resistance transcends the workplace, with the talleres one node in a wider, socially reproductive borderscape. By developing a framework that neither condemns nor celebrates economic structures like the talleres, but instead unpacks their antagonistic nature, the paper highlights the benefits of (a) analysing the autonomy of migration approach compositionally, and (b) further geographical engagement with autonomist thinking.     

RECURSIVE ALGORITHMS FOR THE ELIMINATION OF REDUNDANT PATHS IN SPATIAL LAG OPERATORS*

ABSTRACT. Recursive algorithms for the elimination of redundant paths in spatial lag operators are introduced. It is shown that these algorithms have superior computational properties in comparison with the cumbersome procedure proposed by Ross and Harary (1952). A rigorous definition of spatial lag operators is given, while a number of mathematical results and properties are derived. Theoretical and empirical results regarding the performance of the proposed algorithms are presented.
