This paper attempts to demonstrate the applicability of certain themes from post‐structuralist theory to issues raised by the Mabo judgment and the subsequent debate over native title. It outlines some common features of a post‐structuralist conception of society, commenting particularly on conceptions of freedom and the shared concern with difference. It then shows how questions of difference and identity raised by Mabo may be described in post‐structuralist terms, and contrasts the treatment of difference by Derrida and Deleuze from a political point of view. Finally, the paper suggests ways in which Mabo may be seen as a significant event, and an exercise of freedom, in Deleuzian terms.  相似文献

There has been considerable recent discussion and debate about change and the need for change in the United States Forest Service. A number of observers have argued that the agency has shifted its emphasis from commodity to non-commodity values of the National Forests, has become more sensitive to environmental and ecological concerns, and has become more responsive to public input. However, to date most articles on the topic of change in the Forest Service have been either theoretical and speculative in nature or have based their conclusions on attitude surveys of agency employees. So far no studies have provided “hard,” empirical evidence of change or have conducted any systematic examination of the presumed causes. This symposium attempts to fill this gap. What follows is the presentation of the analyses of a wide range of important quantitative indicators of agency change. From these analyses, we attempt to answer the following questions: Has the Forest Service indeed been changing? If so, what direction has it taken and how significant has this change been? What are the possible causes of change, and what have been the consequences for National Forest policy? What factors are likely to influence future change in the agency?  相似文献

Timber output, the major commodity use of the National Forests, was tracked from 1981 to 1993, to assess changes that have occurred in the amount of timber offered, sold, and harvested. In addition, changes in the method of harvest used on the National Forests were examined to view trends in the management practices of the Forest Service. Although trends regarding changes in timber harvest methods varied from region to region, data on timber offered, sold, and harvested showed a dramatic decrease both nationally and in important timber-producing regions since the late 1980s. This reduction, when seen in the light of other recent studies, suggests that the Forest Service is changing the emphasis of its management practices, placing less priority on the traditional high level of timber output.  相似文献

The Zone Definition Problem in Location-Allocation Modeling   总被引:1,自引:0,他引:1  
Location-allocation modeling is a frequently used set of techniques for solving a variety of locational problems, some of which can be politically sensitive. The typical application of a location-allocation model involves locating facilities by selecting a set of sites from a larger set of candidate sites, with the selection procedure being a function of “optimality” in terms of the allocation of demand to the selected sites. In this paper we examine the sensitivity of one particular type of location-allocation model, the p-median procedure, to the definition of spatial units for which demand is measured. We show that a p-median solution is optimal only for a particular definition of spatial units and that variations in the definition of spatial units can cause large deviations in optimal facility locations. The broad implication of these findings is that the outcome of any location-allocation procedure using aggregate data should not be relied upon for planning purposes. This has important implications for a large variety of applications.  相似文献

Narrative policy analysis and policy change theory rarely intersect in the literature. This research proposes an integration of these approaches through an empirical analysis of the narrative political strategies of two interest groups involved in policy debate and change over an eight‐year period in the Greater Yellowstone Area. Three research questions are explored: (i) Is it possible to reconcile these seemingly disparate approaches? (ii) Do policy narrative strategies explain how interest groups expand or contain policy issues despite divergent core policy beliefs? (3) How does this new method of analysis add to the literature? One hundred and five documents from the Greater Yellowstone Coalition and the Blue Ribbon Coalition were content analyzed for policy narrative strategies: identification of winners and losers, diffusion or concentration of costs and benefits, and use of condensation symbols, policy surrogates, and science. Five of seven hypotheses were confirmed while controlling for presidential administration and technical expertise. The results indicate that interest groups do use distinctive narrative strategies in the turbulent policy environment.  相似文献

The identification of cause‐and‐effect relationships plays an indispensable role in policy research, both for applied problem solving and for building theories of policy processes. Historical process tracing has emerged as a promising method for revealing causal mechanisms at a level of precision unattainable through statistical techniques. Yet historical analyses often produce dauntingly complex causal explanations, with numerous factors emerging as necessary but insufficient causes of an outcome. This article describes an approach that renders complex causal narratives more analytically tractable by establishing measurement criteria for ranking the relative importance of component causes. By focusing on subjectively useful measurement attributes, the approach is well suited to the policy sciences' unique combination of explicitly normative aspirations and a commitment to the systematic assessment of causal claims.  相似文献

Young Avestan nāuuiia-, Old Persian nāviyā, Sanskrit nāvyà-, all descending from Indo-Iranian *nāu̯ii̯a-, are usually glossed by ‘passable (only) by boat, not to be crossed without the help of a boat’. A closer examination of the contexts they occur in reveals that the meaning ‘streaming, raging’ is much more appropriate. In consequence, *nāu̯ii̯a- can not be a secondary derivative of Indo-Iranian *nāu̯- ‘ship, boat’, which is improbable for other reasons as well. It is suggested that *nāu̯ii̯a- rather represents a primary formation derived from the Indo-Iranian root *nāu̯- ‘to flow’.   相似文献
