This paper takes a new approach to investigating people who age in place. It provides an explanation for why people age in a place that can be useful in government and corporate planning. Our research investigates the principal factors that drive the decision of a rising number of older Australians to age in place. Many older people wish to age in place rather than move in with their children or be institutionalised. They wish to continue to be active in their local communities and maintain their existing social ties. The concept of ageing in place covers two distinct groups: those who are able to stay in their current dwellings and age in home and those who move house but remain in their local community and age in neighbourhood. Age-friendly home modification is a response to ageing in home, whereas the provision of institutional healthcare and the provision of age-suitable housing to facilitate downsizing are associated with ageing in neighbourhood. Using Household, Income and Labour Dynamics in Australia (HILDA) survey data, this research examines the mobility decisions of older Australians and identifies the major determinants of a decision to age in place. This research argues for a better understanding of ageing in place, differentiating between those ageing in home and those ageing in neighbourhood.  相似文献

Nielsen, Bue and Sørensen, Peder Michael: Changes in regional employment in Denmark in the seventies. Geografisk Tidsskrift 84, 69–73. Copenhagen, January 1984.

The paper deals with regional development in employment in Denmark in the 1970's. It uses shift-share analysis to isolate elements and activities responsible for the regional dispersion experienced. In that context the paper discusses the interrelationship between manufacturing industries and public services.  相似文献

Drawing on conceptualization of statelessness and ethnographic research on crucial insights of rightessness, this paper investigates how the politico‐geographic‐legality constructs statelessness in the enclaves in India and Bangladesh. Following the decolonization process in 1947, both India and Pakistan/Bangladesh inherited more than 200 enclaves, which comprise 80 per cent of the world's enclaves. With improved bilateral relations, India and Bangladesh officially exchanged the enclaves on 1 August 2015, and the enclave dwellers will gradually be granted citizenship rights over the next few years. In this period of transition from statelessness to statehood, this paper can be read as contemporary history. This paper will draw attention to three aspects of statelessness. First, conceptualization of statelessness not only applies to the refugeehood or de‐territorialization of people but also relates to the process of constructing transterritorial stateless people. Second, this paper will discuss the condition of statelessness constructed in a politico‐geographic‐legal trap. And finally, the paper calls for a wider empirical and critical focus on the hidden geographies of de facto statelessness.  相似文献

1IntroductionMany natural phenomena such as zigzag coastline, various landforms, turbulent rivers, etc. cannot be described with traditional Euclid geometry, but they are of self-similarities. Fractal geometry takes the complex phenomena as its research objects and has been developed into a specific theory. So it has been praised as natural geometry. What is fractal means "irregular, fractional, fragmental" and its core is self-similarity (Wang and Cao, 1995). To characterize fractals differ…  相似文献

The fractal theory put forward by American mathematician B B Mandelbrot (1967) supplies an effective approach to solve complex problems. The complex problems in geography have become the main positive study field of fractal theory. Based on the works of China’s geographers and the summarization of contents of fractal theory, the authors comment on the present situation of its applications to almost every branch of geography and discuss the related problems and the prospects of fractal study in geography.  相似文献
