The war in Iraq, so the widely accepted view, hurt the reelection of George W. Bush. We contend, to the contrary, that the
war helped him get reelected. First, we show that his victory fits the dominant pattern of wartime elections in American history.
Second, we find that Bush’s approval ratings benefited from a complex rally where the Iraq war prolonged rather than diminished
the 9/11 effect; most Americans affirmed rather than disputed a link between the war in Iraq and the war on terror. Third,
while Bush’s approval proves sensitive to U.S. casualties in the Iraq war, any damage to his standing prior to the election
was mitigated by sufficient popular support for that war. And finally, on Election Day, Bush was able to garner the vote of
two critical blocks with favorable feelings about the Iraq war, be it the decision to invade or the prospect of success.

Recent decades have seen an acceleration in public concern about the allocation of increasingly scarce water supplies. There
are many reasons for this concern, such as growth in urban populations. In this article, we focus on how surface water’s special
qualities (the combination of spillovers, rent-seeking behavior, and common pool resources) complicate the assignment of property
rights in any legal framework. These characteristics make specific market structures necessary in order to efficiently allocate
rights. The state usually designs those structures. Yet, just like markets can fail, so can governments fail to effectively
allocate those rights. So designers often turn to quasi-judicial conservancy boards as a second-best solution. We argue that
those boards may themselves fail through a form of “corporation failure.” We address these three types of failures, and offer
an analysis of two cases that suggests that the likelihood conservancy boards will suffer from corporate failure depends on
the actions of the boards and outside stakeholders (like governments).

A new, highly fluorescent dye was synthesised using oleylamine combined with a perylene dianhydride compound. The new dye was characterised by 1H NMR, UV-vis spectroscopy and fluorescence spectroscopy as well as quantum yield. The dye was absorbed onto titanium dioxide nanoparticles for use as a fingerprint detection powder. The new fluorescent powder was applied to latent fingermarks deposited onto different non-porous surfaces and compared with commercial fluorescent powders. The powder exhibits strong fluorescence at 650-700 nm under excitation at 505 nm. On glass surfaces, the new powder gave images showing tertiary-level detail of the fingermark ridges with almost no background development. Compared with current magnetic fluorescent powders, the new powder was slightly weaker in fluorescence intensity but produced significantly less background development, resulting in good contrast between the fingermark and the substrate. 相似文献

Health policy is an important facet of territorial politics,drawing the contours of the sharing community. Changes in themanagement of the division of powers in health policy pointto shifting understandings of the federal political community.This article adopts this approach in the Canadian case, whereobservers disagree about whether values of federal diversityremain robust or are eroding. It considers three Commissions(Rowell-Sirois, Hall, and Romanow) reporting over a 60-yeartime span. The Commissions adopt different understandings ofthe division of powers and of the proper forms of intergovernmentalhealth governance, moving from a robust understanding of federaldiversity and the division of powers in the 1940s, to an afederalemphasis on efficiency and pan-Canadian citizenship in the early2000s. 相似文献
