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.     

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.     

Shopping,social inclusion and the urban geographies of people with intellectual disability

In this paper, we examine the social geographies of people with intellectual disabilities. We focus particular attention on the significance of shopping and spaces of consumption as they relate to questions social inclusion and belonging in the lives of PWID. The focus on consumption offers a useful counterpoint to a prevailing policy emphasis on social inclusion through productive activities. The paper also contributes to the literature on intellectual disability within social and health geography, shedding light on the varied socio-spatial experiences of people beyond the confines of community-care facilities and other separate spaces. Our analysis draws on data collected from a participatory research project in Toronto (Canada). The project involved a small but diverse group of people with intellectual disabilities, who led academic researchers on a series of excursions designed to explore those places and routes that make up their everyday social geographies. Shopping emerged as a significant but often ambivalent theme in the context of these geographies, and the analysis demonstrates the complex interplay of autonomy and control, pleasure and restraint, care and support that shape people’s experiences of consumption. We conclude by discussing the significance of these findings for notions of social inclusion and belonging.     

Humans in the Environment: Plants,Animals and Landscapes in Mesolithic Britain and Ireland

Environmental archaeology has historically been central to Mesolithic studies in Britain and Ireland. Whilst processual archaeology was concerned with the economic significance of the environment, post-processual archaeology later rejected economically driven narratives, resulting in a turn away from plant and animal remains. Post-processual narratives focused instead on enigmatic ‘ritual’ items that economic accounts struggled to suitably explain. Processual accounts of landscapes, grounded in economic determinism, were also rejected in favour of explorations of their sociocultural aspects. However, in moving away from plant and animal remains, such accounts lacked the ability to rigorously explore the specificities of particular landscapes and humans actions within them. This paper will bridge this gap by considering how palaeoecological and zooarchaeological analyses can be used to explore human interactions with plants and animals, which were key in developing understandings and relationships that ultimately structured landscapes, influenced past human actions and shaped archaeological assemblages.     

Envisioning Future Landscapes in the Environmentally Sensitive Areas of Scotland

Environmentally Sensitive Areas (ESAs) designated under EC Structure Regulation 797/85 now cover 1.4 million ha of the Scottish countryside and are likely to make a substantial contribution to the regulation of landscape change. Visual changes to landscapes with (policy on) and without (policy off) the ESA programme in two Scottish ESA areas, Breadalbane and the Machair, are predicted through impact-assessment procedures and computer manipulation of photographic images. The methodological requirements for such predictions are outlined and substantial differences in landscape characteristics under policy on/off scenarios are revealed. Such approaches to landscape change are an essential foundation for the development of environmental cost-benefit analyses and will contribute to public consultation processes.     

Mapping schools' NAPLAN results: a spatial inequality of school outcomes in Australia

This article identifies spatial dimensions of educational outcomes using maps of the 2016 Grade 5 reading results for Australia's National Assessment Program–Literacy and Numeracy for all Australian schools. A geographical information system (GIS) was used to overlay schools' results onto suburbs' advantage or disadvantage to visualise spatial patterns. We then examined the extent to which school results “cluster” in socio‐economically advantaged and disadvantaged suburbs and considered the consistency of spatial patterns for results across major cities. That work illustrates both how GIS can foreground educational inequality and how “the spatial” is more than corollary for student socio‐economic status. Results show substantial differences between urban and remote areas and towns of different size. Maps of cities visualise spatial “clustering” patterns of school results, with most schools in advantaged suburbs having high results and almost no schools in disadvantaged suburbs having high results. Educational outcomes strongly align to local socio‐demographic characteristics, and parallel host communities’ levels of advantage or disadvantage. Differences between public and private schools are less significant than within‐sector differences for schools in advantaged or disadvantaged locales. Patterns in all cities are consistent—schools in advantaged suburbs predominantly have high results, whereas non‐government schools generally perform better than government schools in disadvantaged suburbs. Most concerning is the persistent and increasing trajectory of results in advantaged, and more so in disadvantaged suburbs, of all cities since the first National Assessment Program–Literacy and Numeracy in 2008. Ameliorating spatial inequality between primary schools is one of the greatest challenges for Australians.     

The Newcastle Upon Tyne Peace Society (1817–50)

The 1816 foundation of the Society for the Promotion of Permanent and Universal Peace in London was followed by the creation of a number of Auxiliary societies throughout the country. This paper analyses the history of the Newcastle Auxiliary, covering its establishment in 1817, its disaffiliation from the London Society in 1840, and its subsequent re-affiliation in 1850. After an initial period of quietism after their formation, the paper demonstrates how the radical pacifism of the society developed in the 1830s and 1840s, placing their activities in relation to the specificities of Newcastle’s political history, wider transformations in the British peace movement, and the influence of transatlantic networks of American peace advocacy and anti-slavery activism. The local Richardson family of Quakers personified these transformations, even as anarchists such as Joseph Barker represented a militant outer fringe of the society. Ultimately, however, the society struggled to garner wider support in Newcastle, clashing with local Chartists and with the town’s militarist merchants and businessmen in 1848. The paper therefore demonstrates how the Auxiliary societies need to be thought of active, agential organisations which negotiated the contradictions between their pacifist ideologies and the local and regional milieus within which they were enmeshed.
