In this article, we trace the evolution of punctuated equilibrium theories of the policy process to the development of a full theory of government information processing. Noting that punctuated equilibrium is one realization of a larger theory of government information processing, we outline a research agenda for the study of agenda setting, policy dynamics, and information flows in the policy process. In doing so, we relate the study of government information processing to such important features of American government as inter-institutional dynamics and delegation in the policy process. 相似文献

The development of pottery production during the Bronze and Iron Ages at Tell es-Safi/Gath, Israel, is examined based on the analysis of 224 pottery vessels representing most periods within this ca. 1700 years time frame. The main tools employed were visual examination of manufacturing techniques and petrographic thin section analysis, all of which was conducted on the entire group. This was combined with a chronological, functional, typological, and cultural characterization of the samples. The results indicate a tendency of a diachronic shift from the use of calcareous-based clays to non-calcareous clays, from the Bronze Age towards the late Iron Age, although the primary shaping techniques do not change. Intentional tempering, when relevant, is mostly type- or function-dependent. It is suggested that this trend, possibly evident at other sites in the southern Levant as well, may be related to the employment of higher firing temperatures by the potters. This phenomenon may also be related to the decrease in the relative amount of decorated pottery that is seen during the late Iron Age. 相似文献

This paper re‐examines the chronology of reserve selection in South Australia in the context of changing social, political and economic attitudes. The effect of these changing attitudes on reserve selection in South Australia is assessed in the light of the principles of a comprehensive, adequate and representative (CAR) National Reserve System. The outcome of reserve selection in South Australia is the establishment of a vast network of reserves in the arid regions and many fragmented and small reserves in the agricultural regions. It is likely that the remnant ecological system in the agricultural regions is not representative of the regional environmental diversity and that land clearance has precluded the establishment of a CAR reserve system in South Australia. The rate of reserve selection for nature conservation has decreased over the past decade as the opportunities for reserve acquisition decrease. It is concluded that large‐scale and strategic revegetation will be required to facilitate a CAR reserve system in South Australia. 相似文献

Interfacility Interaction in Models of Hub and Spoke Networks 总被引:3,自引:0,他引:3
Providers of transportation services may reduce their average unit costs by bundling flows and channeling them between hubs (also known as concentrators or routers). The resulting facility locations are interdependent because of the flows between them. This paper analyzes mathematical models of hub systems in an effort to enhance understanding of the optimal location of interactive facilities. The paper examines the behavior of solutions to several alternative models that require the location of a hub at either of two similar locations. A model employing a concave cost function favors the assembly of flows, penalizes fractional facility locations, and produces local minima that have integer facilities. 相似文献

It has been a feature of the past 30 years or so that individual sovereign states have been increasingly willing to partially set aside their own interests in favour of international treaties on pollution control and wildlife protection. It is the political will of the government signatories to such agreements that is the key to successful implementation as that political will provides the legitimate enforceable authority that is necessary to ensure compliance. This paper examines a trilateral agreement made by the Governments of Denmark, Germany and Holland for the protection and management of the Wadden Sea—one of Europe's most important wildlife sites. The examination of that agreement explores the key mechanisms used for its implementation and, in the case of the Wadden Sea, those mechanisms include the operation of key European Union environmental Directives. The paper finds major differences in approach and application of the Birds, Habitats and Environmental Impact Assessment Directives across the Wadden Sea region and argues that these differences undermine the trilateral agreements made by the three governments. 相似文献

Existing histories of public health in Iran often center on elite or urban narratives. This paper shifts the focus to Iran’s villages by examining the twentieth century public health history of rural northern Khuzestan. It argues that Khuzestani villagers desired, rather than resisted, modern medical services. However, vertical decision-making and the prioritization given by public health planners to economic concerns over social well-being led to the uneven distribution of services and failure to fulfill the expectations of Khuzestan’s villagers. This paper uses memoirs, official reports, correspondence, and other records from the Development & Resources Corporation, along with reports from Iran’s Ministry of Education and Ministry of Health, to bring a richer picture of Iranian villagers’ twentieth century history into focus. 相似文献
