This paper examines the validity of the location invariance theorem in Weberian space under various types of uncertainty. The main results are: Given that the firm's location is constrained to remain at a specified distance from the output market, the optimal location is invariant to any change in product demand if and only if the production function is homothetic for a firm facing demand price uncertainty, or if the production function is homothetic and both inputs are risk-neutral for a firm facing technological uncertainty. Alternatively, given that the distance from the firm's location to the output market is a variable, location invariance occurs for a firm facing demand price uncertainty if the production function is linear homogeneous. In the presence of input price uncertainty the optimal location always varies with a change in product demand. The results can include those previously obtained for linear stochastic location models as special cases and some are new contributions to the literature. 相似文献
Questions relating to the ability of particular groups in society to access information and communications technologies (ICTs) have become a growing part of the academic and policy literature. The issues raised in this literature have revolved around a number of themes, many of which can be subsumed under concerns about a growing digital divide whereby society is being divided into information rich and information poor sectors. This differentiation can be between particular social groups irrespective of place, or between people in particular places be these large regional areas (e.g. metropolitan versus non‐metropolitan) or localities and communities within an urban area. This paper focuses on the existence of a ‘digital divide’ across the Sydney metropolitan area. Using ABS 2001 census data the paper presents an analysis of computer and internet access and use for clusters of local communities and focuses on how usage differs across communities as differentiated by socio‐economic status, household and family status and ethnic background. 相似文献

Dominant discourses and strategies of the post-11 September ‘war on terror’ reflect an ideological absolutism that has left the democratic space of civil society in the Asia–Pacific severely curtailed and compressed. Recovery of this distinct space of freedom, so crucial to ‘civilisational’ amity, begins with the strategic deconstruction of the totalising logics and practices underwriting not only the words and deeds of religious militants but also those of state actors. Accordingly, amity is best sought not through uncritical fidelity to essentialist and exclusivist understandings of subjectivity, but acknowledgement and acceptance of the reality that the self is necessarily indebted to the other, to which the former must exercise an ethical responsibility. 相似文献
