Using data describing the historical distribution of county seats in the United States, we (1) replicate the traditional ratio-variable test of the size-density law, (2) test a new multivariate, nonratio form of the law, and (3) introduce an alternative method of testing, one which avoids three possible problems in traditional analyses: ratio-variables, multicollinearity, and logarithmic transformation. 相似文献

Institutions,informality, and influence: explaining nuclear cooperation in the Australia-US alliance
Stephan Frühling 《Australian journal of political science》2020,55(2):135-151
ABSTRACT Nuclear cooperation has been a consistent feature of the Australia-US alliance. In the 1950s and 1960s, Canberra explored transferring US nuclear weapons to Australian forces operating in Southeast Asia. Since the 1960s, Australian governments have supported hosting joint facilities that contribute to America’s ability to execute global nuclear operations. And Australia has regularly invoked the nuclear umbrella as part of the alliance. We explain the key sources of nuclear cooperation in the alliance by leveraging realist and institutionalist theories of alliance cooperation. While realism explains limits to US nuclear commitments in the 1950s, institutional explanations are more relevant in pinpointing the sources of nuclear cooperation and in explaining why Australia has often achieved its policy preferences as the junior partner. 相似文献

Abstract. Private markets constantly assess project investment opportunities across a spectrum of such possibilities. The market's perspective on the boundary of viable projects, however, may be more limited than socially optimal due to informational constraints. In the case of economic development projects in particular, this boundary could be extended by public researchers. This paper constructs a method to estimate the private and social value‐added of such research, providing a new means to understand and assess the public/private sector interface. The framework uses agents' evolving subjective perceptions through Bayesian updating to value research information, along with methods to estimate functional forms and relative optima. Two case studies of regional development research on value‐added agriculture in Colorado highlight the utility of the approach. 相似文献

Fragments of late medieval highly decorated Falke‐group stoneware have been found in excavations all over central and northern Europe. The distribution of the finds points to an origin in Saxony, but the exact centre of production is still unknown. Therefore, a set of samples has been analysed with Neutron Activation and the data compared with Saxon reference groups. The results point to production in a single workshop. The data can be clearly distinguished from all reference groups in our databank. However, the most similar group is that of Zittau, Saxony. Also, one sherd, which is typologically very similar to the Falke group, and which was made in Zittau, suggests that production was based there. 相似文献

An archaeological GIS is used to examine the late eighteenth-century cultural landscape of St. John, US Virgin Islands. Land
use patterns are reconstructed using a combination of historic maps, tax records, and survey reconnaissance. The study demonstrates
significant, heretofore undocumented, transitions taking place that reflect dynamic cultural and economic change within Danish
West Indian plantation society that includes a significant trend towards land ownership by free-colored St. Johnians more
than a half a century before emancipation. These venues of freedom are discussed in relation to broader patterns of estate
consolidation and economic shifts. 相似文献

As a close US ally, Australia is often seen as a recipient of US extended deterrence. This article argues that in recent decades, Australian strategic policy engaged with US extended deterrence at three different levels: locally, Australia eschews US combat support and deterrence under the policy of self-reliance; regionally, it supports US extended deterrence in Asia; globally, it relies on the US alliance against nuclear threats to Australia. The article argues that in none of these policy areas does the Australian posture conform to a situation of extended deterrence proper. Moreover, when the 2009 White Paper combines all three policies in relation to major power threats against Australia, serious inconsistencies result in Australia's strategic posture—a situation the government should seek to avoid in the White Paper being drafted at the time of writing. 相似文献
