This article uses two case studies to illustrate the subjection of indigenous peoples’ marine territories to a ‘double jeopardy’ of exclusion — jurisdictional and proprietary — through the legal and administrative practices of European ‘settler’ states in Australia and Canada. While the fiction of terra nullius as a legal rationale for refuting indigenous rights of property and governance has steadily eroded in recent decades, its counterpart mare nullius has proven, so far, more resistant. The authors examine how state conceptions of jurisdiction, property and boundary‐making in coastal areas accomplish the distortion and fragmentation of the coastal and marine spaces of Torres Strait Islanders in northern Queensland, Australia, and of the Cree and Inuit peoples of James and Hudson Bays in northern Que´bec, Canada. Assumptions of land–sea continuity underlie these peoples’ cultural constructions of coastal and marine environments. In examining the progress that each has made in reasserting ownership and control of coast and sea, it seems that recognition and reinforcement of their institutions for managing marine spaces and resources offer the best prospect for reconnecting fractured jurisdictional domains, and for bringing about social equity, environmental protection, and self‐determined regional development.  相似文献

The balance of sailing vessels makes an important contribution to sailing characteristics, but its measurement is far from trivial. Traditionally, balance has been determined from the geometric centres of hulls and sails, but experimental results show that this approach is highly inaccurate. Designers overcome this difficulty by the use of a heuristic concept of 'lead', but the geometric methodology can be misleading in retrospective analysis of ancient sailing vessels. It can result in doubtful conclusions about sailing capabilities and incorrect deductions about the type of rig that was used and the reasons for specific mast positions.

ABSTRACT A two region model of horizontal innovation with free trade and occupational choice is used to examine the spatial patterns of innovation and manufacturing industry in interior and core‐periphery long‐run equilibria. The inclusion of skill heterogeneity among workers creates a tension between stabilizing productivity effects that coincide with reallocations of workers across industries, and destabilizing productivity effects that arise with localized stocks of knowledge capital. We find that while core‐periphery equilibria are always saddlepath stable, interior equilibria are saddlepath stable when knowledge spillovers exceed a threshold level but are unstable otherwise. In addition, incorporating skill heterogeneity into the model allows for interior equilibria with asymmetric shares for innovation and industry.  相似文献

Conventional migration theory suggests that rural to urban movement was a one-way once and for all movement which resulted in the severance of ties to a rural homeland and the gradual adoption of an urban lifestyle and culture. Analysis of Welsh migration to English towns in the mid-nineteenth century suggests that by no means all migrants conformed to this stereotype. Whilst Welsh migrants displayed similar characteristics to other rural-urban movers and fitted easily into an urban labour market, they were able to retain many of their rural traditions and customs in an English urban environment. They also maintained close links with Wales whilst some engaged in return migration. Although easily accepted into English urban society, the Welsh were able to live in two culture worlds for much of the nineteenth century. It is suggested that detailed longitudinal studies of other migrant groups will demonstrate diversity in the extent to which rural traditions were subsumed by urban culture in the nineteenth century.  相似文献
