SOFT VERSUS HARD: AN AUSTRALIAN STUDY OF AN IDEOLOGICAL BASIS TO ATTITUDES TOWARDS ENERGY USE AND SUPPLY 总被引:1,自引:0,他引:1
Laurence O. P. Knight 《The Canadian geographer》1990,34(1):63-69
A distinguishing factor of western societies is their consumption of energy. In 1986, Canada, the United States, and Australia had per capita consumption rates of 6.3, 4.7, and 3.2 times the global rate, respectively (DIESA 1988). Much of this energy is supplied by fossil fuels. At present, fossil fuels are economically attractive and their relatively high energy densities make them particularly attractive for transport purposes. However, their supply is finite (particularly in the case of petroleum) and their consumption produces atmospheric pollution. The depletion of fossil fuels or a rapid global warming of the atmosphere may eventually force changes in the way developed countries use energy (Lowe 1989). As everyone is an energy consumer, changes in consumption at a societal level are linked with changes at a personal level. 相似文献

The geography of the Canadian economy has long been dominated by heartland‐hinterland contrasts, with manufacturing identified as the dominant function of most heartland cities in analyses of the 1961 and 1971 census data. However, the proportion of employment in manufacturing has been declining in the heartland provinces of Ontario and Quebec over the past fifty years and some geographers argue that the heartland‐hinterland dimension of the regional economy is being overridden by city‐regions that are integrated into global networks of production and trade. The heartland‐hinterland trends are examined using multifactor partitioning (MFP), an advanced shift‐share methodology, for the period of 2001–2006. This is the first intercensal period in which Canadian business has faced the full impact of the removal of North American tariff protection and the increased globalization of the Canadian economy. The data covers employment by eighteen industry sectors for the seventy‐three economic regions defined by Statistics Canada. MFP measures the region and industry‐mix effects, which are interpreted as in the traditional shift‐share model (though they are derived more accurately) and, in addition, an interaction effect. The results demonstrate that the broad heartland‐hinterland differences in the distribution of population and employment growth are increasing not decreasing and that the hinterland is in fact falling further behind the heartland in employment growth. However the Calgary‐Edmonton corridor and the Lower Mainland of British Columbia are emerging as a western heartland. The population size of cities does affect their rates of employment growth, but so too does their location: the growth of heartland cities is outpacing those in the hinterland. The Appendix provides the equations for two‐variable multifactor partitioning. 相似文献

The meaning of contentious collective action has itself always been open to contention. This is true not only of the historiography of revolutions, for example, but also of social science analyses of other, arguably less extreme, forms of contemporary 'contestation'. While up to the 1960s studies of collective action in Europe focused largely on the labour movement, since then much attention has also been paid to 'new' social movements. This article examines some of the methodological and ideological considerations which have shaped the analysis of social movements in France and influenced the debate in recent years as to their significance. 相似文献
