Both Canada and the United States have “pivoted” toward Asia in their foreign policy over the past decade, although emphases in those pivots differed between the two countries. The former focuses on an economic pivot initially, the latter on a security one. What factors explain these shifts? What was the magnitude of policy change by both? Utilizing some important theoretical works by Charles Hermann, we discuss the factors that appear to have brought about this policy change toward Asia, outline the actions and activities that both countries have initiated toward Asia in the past decade to illustrate the type and magnitude of policy change that has occurred, and compare some areas of political, economic, and military similarities between Canada and the United States toward this region. Finally, we assess the likely future of these pivots to Asia in light of the change in political leadership within both nations.  相似文献

Ancient human migrations provide the critical genetic background to historical and contemporary human demographic patterns. However, our ability to infer past human migration events, especially those that occurred over rapid timescales, is often limited. A key example is the peopling of Polynesia, where the timing is relatively well defined, but the exact routes taken during the final stages and the source populations are not. Here, we discuss the technical limitations of current methods for inferring rapid human migration events, using the final stages of Polynesian migration as an example. We also introduce a promising new proxy method to infer human migrations—patterns of bacterial evolution within ancient dental calculus (calcified plaque). While we focus on Polynesia, this method should be applicable to other past migrations, enhancing our understanding of human prehistory and revealing the crucial events that shaped it.  相似文献

This article shows that, in the study of immigrant integration policy in the U.S. states, it is critical to report data and coding decisions for individual laws. This analysis uses an updated and public database of law‐level decisions, which includes 2,703 legislative actions recorded by the National Conference of State Legislatures from 2005 to 2016. These data are used to estimate models of aggregate state policy activity in a variety of ways: as a single continuum of policy balance versus separate models of welcoming and hostile, lumping all policy subareas together versus analyzing a specific subarea, and lumping all years together in one cross section versus panel analysis. The results in these models differ enough to indicate that reporting codes for individual‐level laws is absolutely essential so that each researcher easily can construct the measure that fits his or her theoretical framework best.  相似文献

The jurist A. V. Dicey’s study of the Law of the Constitution (1885) has been since its publication the dominant analysis of the British constitution and the source of orthodoxy on such subjects as parliamentary sovereignty and the rule of law. This canonical status has obscured the originality of Dicey’s ideas in the history of legal and political thought. Dicey reworked the traditional idea of sovereignty into two separate concepts – legal and political sovereignty – in order to square the common law notion of the sovereignty of parliament with the democratic idea of the sovereignty of the people. He forged a new concept – ‘the rule of law’ – to explain the legal basis of liberty in common law countries in a manner that was both Benthamite and constitutionalist. Finally, he provided a democratic and anti-federalist rationale for maintaining the Union of Great Britain and Ireland. This majoritarian, centralist and utilitarian constitutionalism has been one of the most enduring products of Victorian scholarship. This article seeks to recover it in its original context and, in so doing, to show the value of reintegrating legal thought into the mainstream of modern British history and the history of political thought.  相似文献
