In 2006 volcanic glass deposits on Vanua Lava and Gaua Islands were re‐visited and systematically sampled. Twenty‐nine source samples were analysed using EDXA‐SEM and LA‐ICP‐MS with a focus on detecting possible intrasource variation. The results show both Banks Islands deposits are readily distinguishable from each other and from other sources in the region and their chemical compositions are highly homogenous. Surface survey of other prospective areas established that these two are the only volcanic glass sources in the Banks Islands.  相似文献

This contribution considers the spatial distribution of foreigners in Brussels. Fifteen nationalities are considered, among which a group of affluent foreigners linked to the international functions of the city (EU Capital and NATO headquarters) and a poor group whose beginnings can be traced to the ‘guestworkers’ immigration in the late sixties and early seventies. Firstly, the population structure of Brussels and the position of its foreigners are outlined in a historical perspective. Then, the housing market structure and its spatial distribution are explained. Both elements are crucial to the understanding of the contrasting residential distribution of the affluent foreigners and the guestworkers. Finally, the changes in the composition of the foreign communities between 1981 and 1991 are examined and related to processes of urban restructuring. They express the passage from a Fordist to a post-Fordist city whereby spatial patterns merely change, but deepening contrasts in the social structure appear.  相似文献

This article describes and tests a process which generates the 'pro-coalition gender gap' in electoral behaviour which has been observed in recent research. More detailed analysis, however, indicates that this gap is more apparent than real: for almost three-quarters of the electorate (those who are not members of trade unions) the electoral behaviour of men and women is virtually identical. Further, sex segregation in the workforce appears at least as much as women's participation in the workforce to underlie the 'pro-coalition' gap. These results imply that this (at least partially artifactual) gap is likely to persist into the foreseeable future.  相似文献

In the international literature on urban tourism most research concentrates on cities and tourists from the global North. The patterns of urban tourism development unfolding in emerging destinations of the global South exhibit differences to the well‐documented experiences of cities in North America or Western Europe. One factor is the influence of regional tourists. It is evident South Africa's tourism economy is dominated by African tourists. Likewise, the urban tourism economy of Johannesburg is distinguished by regional tourists. This paper examines the role of ‘Southern’ tourists in urban tourism and of policy responses by Johannesburg authorities to promote shopping tourism as an element of local economic development planning.  相似文献

In the global profile of scholarship on tourism geographies, Africa is the least represented continent. With Africa's incorporation into the global tourism economy, considerable optimism has been raised by many national governments as well as external international development agencies as to the potential contribution of tourism for social and economic development across the continent. The number of geographical voices interrogating the nexus of tourism and development is small but expanding. This paper provides a review of the existing paths and new directions of tourism geographies of the region of Southern Africa as the context for this special dossier. It is argued that tourism research and debates in Southern Africa are growing in importance, including an expansion of geographical research.  相似文献
