Few people inside or outside government have had a greater impact on public policy in Australia than Ross Garnaut. His report in 1990 provided a blueprint for Australia's economic ‘engagement’ with Asia, whether or not one agreed with its underlying logic and analysis. The reception of his report on climate change in 2011 could hardly have been more different. Why is it that some ideas enjoy wide support from influential actors and are enthusiastically taken up by policymakers, while others struggle to gain traction, even when backed by government? This paper provides some possible answers to this puzzle by identifying factors that facilitate or obstruct the influence and impact of ‘policy entrepreneurs’.

在澳大利亚政府内外,对公共政策影响最大的人士莫过于郜若素了。他发表于1990年的报告,你同意其逻辑分析也好,不同意也罢,反正它都为亚澳经济关系提供了蓝图。他于2011年发表的环境报却得到迥然不同的反应。何以一些观点能够得到重要社会主体的广泛支持以及政策制定者的积极采纳,而另一些观点哪怕是有政府做后盾,也难得推广呢?本文通过寻找有利或有碍“政策专业户”发挥影响的因素,对这个问题作了回答。  相似文献

Conventional wisdom before the Vietnam War held that public opinion exerted no influence on U.S. foreign policy decisions. Scholars working in Vietnam's aftermath found episodic influence of public opinion on foreign policy, but missing in our understanding were longitudinal examinations of public opinion's influence on foreign policy. A number of post-Vietnam scholars subsequently revealed a long-term relationship between public opinion and defense spending. This study extends that work by analyzing responsiveness to public opinion in different foreign policy arenas by different government institutions, and by accounting for a critical variable not relevant in most previous studies: the end of the cold war. We construct a model explaining the influences of public opinion and the cold war on spending proposals for defense and foreign economic aid by the presidency, the House of Representatives and the Senate. Both public opinion and the end of the cold war exert direct influence on defense spending proposals by the presidency, while the Senate and the House respond primarily to public opinion inputs and the partisan composition of the Senate. In the case of foreign economic aid, the cold war's end gives occasion for increasing spending proposals, contrary to the public's expectation that the end of the cold war minimized the need for the U.S. to provide foreign economic assistance.  相似文献

Some 10,000 years ago with the disappearance of the last Devensian ice, the climate of the British Isles began a slow but general warming. This continued until the middle of the fifteenth century when the Little Ice Age developed, ushering in several centuries of colder weather and violent fluctuations in weather associated with the expansion of the circumpolar vortex. Detailed information of the effect on Scotland's weather of this major climatic disturbance is rare but The Chronicle of Fife written in the seventeenth century by John Lamont does provide some remarkable insights.  相似文献

Four miscellaneous artefacts, which do not correspond to the other major small finds groups, are also included in the Sharm assemblage. Whilst the gastropod shell is positively identified as Tonna luteostoma, the materials and function of the remaining objects are conjectural.  相似文献

The onset of Little Ice Age conditions in California’s Sierra Nevada mountains resulted in increased temporal and spatial variability, and hence uncertainty regarding the distribution and production of resources targeted by its inhabitants, the Western Mono. The Mono responded with a risk-averse strategy composed of lowland winter population aggregation supported by logistical forays and seasonal residential dispersals to the high country, both ways of averaging variance in environmental productivity. These patterns were reconstructed using surface archaeology, GIS, and two straightforward spatial statistics, nearest-neighbor and variance-to-mean ratios, that combined provide a robust, objective picture of population aggregation and dispersal and the scale of these phenomena in different environments and seasons. These diverse strategies conform to expectations regarding the best ways for hunter–gatherers to cope with uncertainty, particularly in mountain environments. Despite this, the residentially mobile aspect of the pattern is rare in mountains and probably the result of historical connections between the Mono and Great Basin groups employing similar behaviors. Ultimately, this research suggests that climate change and environmental variability condition risk-averse, satisficing economic behaviors focused more on security than optimization, implying that pronounced environmental variability runs counter to economic intensification and its association with the evolution of more complex societies.  相似文献

Between ca. 6000 BC and ca. 500 BC, barley cultivation spread across the continent of Europe from the extreme south to the extreme north. Carbon-dating would suggest that this spread, and indeed the spread of crop cultivation generally, varied in its pace, with ‘delays’ at certain points along its route. Such delays in the spread of agriculture have been explained as resulting from the slow assimilation of agricultural practices by existing indigenous human populations or as the time taken for the crops to adapt to novel climatic conditions, such as altered temperature regimes and day-lengths. A mutant form of the photoperiod response gene, Ppd-H1, causes barley to be non-responsive to long days, while the wild-type responsive form allows plants to flower in response to long days. We sequenced this gene in 65 ‘historic’ barley accessions, from the late 19th and early 20th centuries, in order to explore the potential role of environmental adaptation in the spread of agriculture. We chose to use ‘historic’ material, to complement the richer patterns in extant genetic lines, by spreading the data range in both time and space. Our ‘historic’ barley data shows a latitudinal divide in the Ppd-H1 gene similar to that found in extant lines, but with clearer geographical resolution, and extending northwards into the Arctic Circle. We discuss the implications of our results in relation to the dynamics of agricultural spread across Europe.  相似文献

Much has been said since the 2000 presidential election regarding the administration of elections in the United States, particularly about how election administrators are selected and to whom they are responsive. Unfortunately, there has been little research on the different administrative structures that are possible and the preferences of Americans regarding these different administrative options. In this article we present the results from a national survey of American adults in which we asked them their preference for whether elections should be run by partisan or nonpartisan officials, whether the officials should be elected or appointed, and whether the administration of elections should be by a single unitary executive or by an election board. In addition to eliciting the basic preferences of Americans about these administrative choices, we also undertake a deeper analysis of these data to determine the underlying patterns in support for the different administrative options.  相似文献

Investigations of the relationships between culture and biology among prehistoric populations of the southwestern United States can enhance our reconstruction of social interactions. The present study analyses the permanent dentition of Basketmaker II and Mimbres individuals from multiple sites using the Arizona State University dental anthropology system, and compares them with a regional sample. Discrete dental trait analysis provides a useful means for assessing the degree of genetic relatedness between populations when large comparative samples are available. Both in situ cultural change and population replacement have been posited as the dominant mechanism acting on Basketmaker and early Puebloan groups. We examine the relationship of these populations to probable Uto‐Aztecan speakers in light of the Uto‐Aztecan farmer migration hypothesis. The Basketmaker II complex, traditionally recognised as a distinct cultural unit, exhibits considerable population heterogeneity. Western Basketmakers appear to share biological ties with Uto‐Aztecan speakers, while Eastern Basketmakers do not, as predicted by the model. The relationship of the Mimbres to probable Uto‐Aztecan speakers is less clear because the Mimbres show only weak affinities to northern Mexican populations.

Abstract How do firms in nonrenewable resource industries respond to changes in state taxes? This paper presents simulations of changes in state production (severance) tax policy on the timing of exploration and output in Wyoming. The framework developed allows for interactions between taxes levied by different levels of government. Results suggest that oil production is highly inelastic with respect to changes in production taxes. Policy implications suggest that increases in production taxes on oil risk little loss in future production. The extent to which these results may generalize to other oil producing states is considered. JEL Codes: H71, Q32  相似文献

This article examines the travels and appearances of Canadian Mohawk writers, lecturers, and performers E. Pauline Johnson and John Brant‐Sero, who appeared in Britain as self‐identified Mohawks, Canadians, and members of the British Empire during the late‐Victorian and Edwardian years of heightened imperial sentiment. The article draws upon feminist scholarship on performance, imperialism, and culture and consumption for the late‐Victorian and Edwardian period. It argues that, while Johnson and Brant‐Sero challenged stereotypes of Mohawk gender relations, they also were part of imperialist modernity; their gendered ‘performances’– on and off‐stage – must be analysed within the context of the gendered cultures of consumption and performance of late‐Victorian and Edwardian British society.  相似文献
