ABSTRACT This study comprises an investigation of Europe's motives to develop the independent satellite navigation system known as Galileo, despite the existence of America's successful – and freely available – Global Positioning System (GPS). The study begins with an analysis of both systems to familiarize the reader with global navigation satellite systems (GNSS), to provide an understanding of the strengths and weaknesses of GPS and Galileo, and to highlight the systems' similarities and differences. Although the two systems have different founding principles, they employ similar infrastructures and operational concepts. In the short term, however, Galileo will provide better accuracy for civilian users, at least until GPS upgrades take effect. But performance is only part of the rationale. The author contends that Europe's pursuit of Galileo represents a desire for enhanced performance and independence, as well as an economic incentive. With Galileo, Europe hopes to achieve political, security and technological independence from the United States. Additionally, Europe envisions overcoming the US monopoly on GNSS by seizing a sizable share of the expanding GNSS market and setting a new world standard for satellite navigation. Finally, the author explores Galileo's impact on the United States and reviews US policy towards Galileo. The article concludes with recommendations to strengthen the competitiveness of GPS. 相似文献

The objectives of this article are to assess whether or not the feminisation of agriculture is occurring in China, and if so, to measure its impact on productivity. To meet these objectives, we rely on three data sets that allow us to explore who works on China's farms and the effects of the labour allocation decisions of rural households on productivity. We find that since the late 1990s, the role of women has increased in both the supply of farm labour and in the duties that they take on in the management of farms. While this expansion is important, we further demonstrate that when women do a majority of farm work or manage the farm, their farms are equally efficient as farms managed by men. 相似文献

Establishing correspondence between the upper portion of a white birch sapling, a suspected weapon, and a potential source from a stand of trees was posed to one of us (GMC). A bending force shattered the sapling, precluding physical matching. Three white birch saplings were taken from the same stand of trees in a similar manner. Correspondence was achieved by measuring the width of the annual rings along four radii from a disk cut above and below the break. The regression coefficient of the data from the two disks from the same sapling was r2 = 0.95. Regressing the upper disk against the lower disk of two other saplings resulted in r2 values of 0.26 and 0.17, respectively. The various characteristics that are confined to a wood stem as part of its normal process of growth can be used to eliminate candidate saplings and establish correspondence between two pieces of wood. 相似文献

Existing research on public opinion related to race and immigration politics emphasizes the role of prejudice or bias against minority groups. We argue that the social norm against prejudice, and individual motivations to comply with it, are crucial elements omitted from prior analyses. In contemporary Western societies, most citizens receive strong signals that prejudice is not normatively acceptable. We demonstrate that many majority‐group individuals have internalized a motivation to control prejudiced thoughts and actions and that this motivation influences their political behavior in predictable ways. We introduce measures capturing this motivation, develop hypotheses about its influence, and test these hypotheses in three separate experimental and nonexperimental survey studies conducted in Britain and Germany. Our findings support a dual‐process model of political behavior suggesting that while many voters harbor negative stereotypes, they also—particularly when certain contextual signals are present—strive to act in accordance with the “better angels of their natures.” 相似文献

Preventing large‐scale atrocities has emerged as an important policy goal of the post–Cold War period. However, a debate exists about the effects of creating an international institution to prevent atrocities. Advocates of intervention argue that a credible threat to intervene should deter perpetrators and stop atrocities when deterrence fails. Critics argue that third‐party intervention, by strengthening weak minority groups and lowering the cost of war, encourages rebellions and so makes war and atrocities more likely. We develop a model of intervention to analyze this debate. The model shows that the negative effects of intervention highlighted by critics can be mitigated if the third party is relatively neutral and if alternative costs are imposed on decision makers. We conclude that with appropriate institutional design, the net impact of stronger third‐party commitments to end atrocities will be to lower the expected level of atrocities. 相似文献

The conclusion of the World Trade Organization’s (wto) ninth ministerial meeting – held in Bali 3–7 December 2013 – is at one and the same time momentous, marginal and business-as-usual. It is momentous because it marks the first multilateral agreement reached in the wto since the organisation began operations on 1 January 1995; it is marginal because the deal reached will have only a limited impact on the global trading system; and it is business as usual because the Bali package will be of disproportionally greater value to the industrial states than to their developing and least developed counterparts. We examine what happened in Bali, covering the principal issues at stake and the content of the outcome, what this means for the wto and for the Doha Development Agenda (dda), and why it all matters. We argue that, while the Bali ministerial is significant and the agreements reached important, the conclusion of the meeting and the package agreed represent only a limited movement forward in addressing the fundamental problems and inequities of the wto system. 相似文献

This article was written at the request of the Secretary of Defense Task Force on DoD Nuclear Weapons Management. While this analysis suggests that certain types of terrorists can be deterred from certain types of attacks, it is less optimistic about the use of nuclear weapons in a terrorist deterrent strategy. A broad approach to deterrence may be effective against certain types of terrorist groups and attacks, making it crucially important to disaggregate the terrorist threat when setting policy. The article goes on to address two types of terrorist groups with a “global reach” that pose a serious threat to the United States: non-state actors driven by doctrines permitting catastrophic attacks and state-sponsored groups capable of carrying out catastrophic attacks. The analysis reveals a number of previously unappreciated tradeoffs and paradoxes associated with the deterrence of terrorists. 相似文献
