A FIELD METHOD FOR INVESTIGATING the DISTRIBUTION of ROCK ART

Summary: Recent studies of prehistoric rock art have analysed its position in the landscape and have suggested that it played an important role in a mobile pattern of settlement. But the distribution of petroglyphs is usually taken as given, with the result that it is difficult to assess the significance of this kind of patterning. We argue that such evidence should be compared with the distribution of uncarved rocks across the surrounding area, and illustrate this procedure by two case studies from northern England. In these examples rock carvings were carefully sited at viewpoints and may have overlooked important routes across the landscape.     

Sodic metasomatism in the Palaeoproterozoic Hotazel iron-formation, Transvaal Supergroup, South Africa: implications for fluid–rock interaction in the Kalahari manganese field

Petrological and geochemical evidence is presented on the occurrence of aegirine in the Palaeoproterozoic Hotazel iron‐formation, which hosts the giant manganese deposits of the Kalahari manganese field, South Africa. The mineral has an essentially pure Na end‐member composition and occurs sporadically in iron‐formation immediately bordering the manganese ore beds. The development of aegirine appears to have taken place due to the action of late‐infiltrating, saline hydrothermal fluids at the expense of a pre‐existing, binary quartz–hematite assemblage. It is proposed that such a process would have overprinted (and therefore post‐dated) a spatially more extensive, low‐temperature alteration event which brought about thorough carbonate leaching, oxidation and residual enrichment of metals in the Hotazel iron–manganese rocks.     

Children and Urban Regional Planning: Participation in the Public Consultation Process through Story Writing

Blue Mountains City is a unique urban area of 75 000 people, located along a narrow mountain ridge and within a world heritage national park, between 60 and 120 kilometres west of Sydney, New South Wales, Australia. The Blue Mountains City Council is currently developing a regional city strategy to guide development over the next 25 years. All sections of a very diverse community have been consulted in the public participation process, including children aged between six and 12 years. This paper deals with the analysis of 269 entries for a children's story-writing competition organised by the council. The children had to imagine that they were adults in 2025 and write a story about what their home and city would be like at that time. The paper discusses the complex problems of consulting with children on strategic regional planning matters, and the results from analysis of these competition entries in the light of those problems. The most important issues for the children as a whole were the impact of traffic, the impact of urban development on residential neighbourhoods, places for children to play, protection of the natural environment, for which the city is famous, and the ability to keep domestic pets. One of the most significant impressions emerging from the analysis is that children were far from optimistic about the future. Thirty-five per cent of entries had a negative tone, whereas only 24% were positive. The remaining 41% were written in a matter-of-fact narrative style that indicated neither enthusiasm nor disappointment with the future of the city. The children were more or less evenly divided on whether the future would be strongly based on advances in technology, much the same as now, or based on simpler technology than at present. The technique of story writing, despite some methodological difficulties in this particular case, was a useful tool for consultation with children of this age group.     

Interrogating borders: a transnational approach to refugee research in Vancouver

Immigration is predicated on the centrality of the nation‐state. The authors argue that analyzing settlement patterns and successful integration within a strictly national context is insufficient to understand the political, social, and economic relations which shape the lives of refugee immigrants in Canada. To support this claim, a less state‐centric theoretical framework of transnational migration is outlined. The paper examines methods emerging from transnational migration, focussing in particular on research with Burmese refugees who have settled in the Greater Vancouver Area. Based on 50 personal interviews conducted with refugee newcomers from Burma who are now settled in the Lower Mainland, the authors use the case study as a basis to raise methodological and theoretical questions about immigration research. We argue that the very politics of doing research with this group of refugees and other immigrant groups are shaped by the relations of power experienced before arriving in Canada. Les auteures soutiennent que l'analyse des schémas d'établissement et d'intégration réussie dans un contexte strictement national s'avère insuffisante pour comprendre les relations politiques, sociales et économiques qui définissent l'existence des réfugiés immigrants au moment de l'arrivée. Dans le but d'appuyer cette proposition, nous définissons un schéma théorique moins axé sur l'état, c'est‐à‐dire le transnationalisme. La recherche examine ces facteurs en relation avec les expériences des ‘immigrants non‐traditionnels’ au Canada, en particulier les réfugiés Burmans installés dans la région de Vancouver. Basés sur 50 entrevues personnelles menées avec des réfugiés nouvellement arrivés du Burma et qui sont maintenant installés dans le ‘Lower Mainland’, les auteures utilisent l'étude de cas comme une base permettant de soulever des questions de méthodologie pour la recherche en immigration. Nous avançons que les implications politiques de la recherche avec ce groupe de réfugiés et d'autres groupes d'immigrants dépendent des relations de pouvoir vécues avant l'arrivée au Canada.     

COMPONENTS OF CHANGE IN THE SPATIAL DISTRIBUTION OF THE ELDERLY POPULATION IN ONTARIO, 1976–1986

Although the elderly population is increasing rapidly in all parts of Canada, the pattern of change is far from uniform. A number of properties of the aging process are strongly differentiated at the county and township levels, variations which have considerable significance for the design and implementation of social service and health care systems. Using data from the 1976, 1981, and 1986 Censuses for Ontario, components of change in the elderly population are obtained by cohort survival methods. The significance of rapid metropolitan growth of the elderly compared with the slow growth of the rural elderly is highlighted, while intra-county distributional shifts in the elderly population raise important questions for the next decade.
Quoique l'âge de la population augmente rapidement à travers le Canada, ce changement nes'opèrepas de façon uniforme. Certaines caractéristiques du processus de vieillissement sont vraiment differentes à l'échelle des comtés et des municipalités. Ces différences sont d'une grande importance lors de la création etde l'implantation des services-santé et des services sociaux. À l'aide des statistiques de recensement pour les années 1976, 1981, et 1986 pour l'Ontario, les facteurs de changement des populations de personnes âgées sont obtenus au moyen des paramètres de 'survie des groupes.' La signification du taux d'accroissement rapide des personnes â gés en milieu urbain comparé au taux d'accroissement plus lent de ces mêmes personnes en milieu rural est mise en évidence. Les variations de la distribution de cette population d'un comtéà I'autre soulèvent d'importantes interrogations pour la prochaine décade .
