ABSTRACT

One of the most persistent themes in the debate on Canadian foreign policy over the past few decades concerns the influence Quebec is thought to possess over the design and implementation of Canadian foreign and defense policy. Our purpose in this article is to situate this general debate within a more specific context, of Canada’s grand strategic choices as they principally involve the country’s security and defense relations with the US. To do this, we adopt somewhat of a “counterfactual” tack; to wit, we inquire whether, in the absence of Quebec from the Canadian confederation, we should expect to have seen a fundamentally different grand strategy fashioned by Ottawa, one with different significance for relations with the US. We focus on two specific cases, both of which have figured prominently in recent Canadian–American strategic relations: the war in Afghanistan and the invasion of Iraq. We conclude that while there is something to the claim that Quebec can and does boast of a certain “specificity” in the matter of Canada’s grand-strategic preferences, it is hardly the same thing as arguing that the country without Quebec would have adopted policies on both Afghanistan and Iraq that were fundamentally different from the ones it chose to follow.  相似文献

SUMMARY: In 1842 the former first government house located at Okiato, New Zealand, burnt to the ground and the site was abandoned. A well on the site was excavated in 1994–95, revealing a base layer of burnt timbers, a Maori digging stick and ceramic sherds with an estimated manufacture date range of 1823–41. We argue that this deposit is derived from the 1842 destruction of the Okiato government house building. An analysis of the wood identified kauri (Agathis australis) and kahikatea (Dacrycarpus dacrydioides), confirming that the building was not a prefabricated imported structure, but rather was constructed on site from locally available timber.  相似文献

Many experiments have sought to recreate the types of damage that would be expected in ancient stone and bone weapon tips. This damage is usually presented as visible fractures or microscopic surface modification. Fatigue tests conducted on bovine bones, however, show the development of internal micro-cracks that result from stress, prior to actual breakage. In this paper I present the results of an experimental investigation of bone points subjected to a variety of activities. I assess the presence of microdamage using micro-focus computed tomography. The results show that two patterns of micro-cracks develop in bone and are best viewed in longitudinal section. Micro-cracks are a cumulative feature dependent on the amount of load applied and the duration of activity. When subjected to high enough loading rates, micro-cracks will merge together to eventually form a fracture. Although further tests are needed to confirm the exact point at which these fatigue fractures begin to form, micro-focus computed tomography has the potential to reveal whether an individual bone point underwent multiple or prolonged impacts and thus to elucidate the probable function/s of ancient pointed bone tools where no visible damage is apparent. Micro-focus computed tomography is a non-destructive and non-invasive procedure and therefore safe to use on archaeological artefacts.  相似文献

This study explores issues in using data generated by other analysts. Three researchers independently analyzed an orphaned, decades-old zooarchaeological dataset and then compared their analytical approaches and results. Although they took a similar initial approach to determine the dataset’s suitability for analysis, the three researchers generated markedly different interpretive conclusions. In examining how researchers use legacy data, this paper highlights interpretive issues, data integrity concerns, and data documentation needs. In order to meet these needs, we propose greater professional recognition for data dissemination, favoring models of “data publication” over “data sharing” or “data archiving.”  相似文献

Abstract

The coordinated behavior of members of a state delegation to the U.S. Senate can provide constituents in a state greater representation in Congress. Despite this potentially improved level of representation through coordination, popular and scholarly accounts of the U.S. Senate often feature senators from the same state at odds with one another on a variety of policy issues. In this research, we investigate competing expectations regarding the frequency (across topics) of collaborations between members of a state delegation to the Senate. We then test our expectations using patterns in bill cosponsorship in the 103rd–110th U.S. Senates. We find that senators from the same state work together often on the development of legislation, and that this coordinated activity is consistent across a variety of bill topics across many sessions of congressional activity. Notably, same-state status is an even stronger predictor of support via cosponsorship than is same-party status, raising possible avenues of breaking through partisan gridlock.  相似文献

Recently, disaggregate modeling efforts that rely on microdata have received wide attention by scholars and practitioners. Synthetic population techniques have been devised and are used as a viable alternative to the collection of microdata that normally are inaccessible because of confidentiality concerns or incomplete because of high acquisition costs. The two most widely discussed synthetic techniques are the synthetic reconstruction method (IPFSR), which makes use of iterative proportional fitting (IPF) techniques, and the combinatorial optimization (CO) method. Both methods are described in this article and then evaluated in terms of their ability to recreate a known population of firms, using limited data extracted from the parent population of the firms. Testing a synthetic population against a known population is seldom done, because obtaining an entire population usually is too difficult. The case presented here uses a small, complete population of firms for the City of Hamilton, Ontario, for the year 1990; firm attributes compiled are number of employees, 3-digit standard industrial classification, and geographic location. Results are summarized for experiments based upon various combinations of sample size and tabulation detail designed to maximize the accuracy of resulting synthetic populations while holding input data costs to a minimum. The output from both methods indicates that increases in sample size and tabulation detail result in higher quality synthetic populations, although the quality of the generated population is more sensitive to increases in tabular detail. Finally, most tests conducted with the created synthetic populations suggest that the CO method is superior to the IPFSR method.  相似文献

For many decades the use of backed pieces from the Howiesons Poort, between about 70 ka and 55 ka ago, in South Africa has been a point of discussion. Recently direct evidence has been provided to associate these tools with Middle Stone Age hunting strategies. Yet, whether they were used to tip hunting weapons or as barbs remained an open question. In this paper we introduce a set of pilot experiments designed to test the effectiveness of Howiesons Poort segments, the type fossils of the industry, hafted in four different configurations as tips for hunting weapons. It is shown that the morphological type can be used successfully in this way. We present the results of a macrofracture analysis conducted on the experimental tools and compare these to results obtained from three Howiesons Poort backed tool samples. By correlating experimental outcomes, macrofracture data and the interpretation of micro-residue distribution patterns, we provide some insight into the functional variables that might be associated with Howiesons Poort segments.  相似文献
