Traditionally, public space has been perceived as an integral part of fully functioning liberal democracy. Yet much research argues that public space is in decline due to regimes of neoliberal governance paralleled with a growth in quasi-public spaces such as shopping malls, casinos and gated communities. It is argued that these new spatial forms posit a commercialised, sanitised and ultimately exclusionary urban form in place of more egalitarian, engaging and ultimately democratic public spaces. Increasingly, however, urban research has questioned the veracity of the claims made about the nature of traditional public space as well as investigating the marginal and contingent nature of publicness as constituted by and enacted in a variety of places. Drawing on Foucault's concept of heterotopic space, this paper reports on a qualitative study based on focus group interviews conducted with users of a suburban shopping mall in Sydney's southwest. The research uncovers both a more complex and less overtly deterministic publicness than has previously been identified in such spaces. From these findings the paper argues for a conception of publicity which moves beyond the zero-sum game approach endemic in much work in this area to one which analyses the qualitative effect quasi-public spaces are having on the nature of publicness in the Australian context. The paper concludes by arguing that a rethinking of publicness allows room for the emergence of a more progressive public ethic.  相似文献

Cryptocrystalline silicates from the Chadron Formation were widely used by prehistoric human groups in the Great Plains of North America. There are two documented quarry areas: Flattop Butte in Colorado and the White River Badlands of South Dakota. Cryptocrystalline silicates from these sources are visually indistinguishable, making it difficult to determine the sources of artefacts found at archaeological sites. In this investigation, neutron activation analysis is used to distinguish the two sources. This technique also identifies lithic material from the Clovis-age Eckles site in Kansas as being from Flattop Butte.  相似文献

Scholars of Canadian politics have noted that the Prime Minister plays a dominant role in shaping domestic and foreign policy. This article examines the role of the Prime Minister in shaping Canadian foreign policy toward Israel since 1993 and shows the central role that the Prime Minister has played on this issue. It specifically argues that Stephen Harper produced a noticeable pro-Israel shift in Canada’s policy and moved Canada away from the multilateralist approach pursued by Jean Chrétien and, to a lesser extent, Paul Martin. But this article also argues that Justin Trudeau has so far embraced a policy that largely reinforces the approach of Harper rather than rejecting it. Thus, one practical implication of the dominant role of the Prime Minister in shaping Canada’s policy toward Israel is that Canada has become more one-sided in its support of Israel in the past two decades.  相似文献

Rozefelds, A.C., Dettmann, M.E., Clifford, H.T. & Lewis, D., August 2015. Macrofossil evidence of early sporophyte stages of a new genus of water fern Tecaropteris (Ceratopteridoideae: Pteridaceae) from the Paleogene Redbank Plains Formation, southeast Queensland, Australia. Alcheringa 39,. ISSN 0311-5518.

Water fern foliage is described from the Paleogene Redbank Plains Formation at Dinmore in southeast Queensland. The material, which is based upon leaf impressions, records early sporophyte growth stages. The specimens occur at discrete levels in clay pits at Dinmore, and the different leaf stages present suggest that they represent colonies of young submerged plants, mats of floating leaves, or a mixed assemblage of both. The leaf material closely matches the range of variation evident in young sporophytes of Ceratopteris Brongn., but in the complete absence of Cenozoic fossils of the spore genus Magnastriatites Germeraad, Hopping & Muller emend. Dettmann & Clifford from mainland Australia, which are the fossil spores of this genus, it is referred to a new genus, Tecaropteris. The record of ceratopterid-like ferns adds significantly to our limited knowledge of Cenozoic freshwater plants from Australia. The geoheritage significance of sites, such as Dinmore, is discussed briefly.

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

In 2014, the Supreme Court of Canada ruled that the unelected nature of the Senate is an inherent feature of Canadian parliamentary democracy and is a central pillar of the constitution. Members of the Upper House are appointed by the Governor General, acting on the advice of the Prime Minister. The decision taken by the Prime Minister is not subject to review by Parliament or the provincial legislative assemblies. Patronage appointments have given the Senate a reputation as a dumping ground for political friends and party insiders. In 1989, the province of Alberta enacted the Senatorial Selection Act, arguing that it would serve as a stepping stone for substantive reform to the Senate. The province has held four elections in which the people of the province have chosen senators-in-waiting. This article argues that the Court’s opinion in Reference re Senate Reform undermines the foundation upon which the provincial statute rests.  相似文献

The interpretation that a rock has been subjected to cultural utilization is a basic element of hunter-gatherer research. The fracture mechanics of the flaked stone tool production process are well understood and the material residues are routinely identified during fieldwork. Conversely, non-percussion processes such as hot-rock technology, which can result in rock fracture, are less well understood. An experimental study has been developed to examine the fractured gravels observed at a prehistoric site on the Southern Plains (USA). The experiment has sought to determine whether cultural or natural agencies were responsible for the production of the angularly fractured rocks. The positive results of the experiment indicate that not only were humans most likely responsible for the breakages, but also that the fractured rocks often exhibit distinctive morphologies that may be identified during fieldwork. This simple experimental methodology is applicable to other hunter-gatherer sites where the depositional environment is not conducive to the structural preservation of features such as hearths.  相似文献

New TFP estimates drawn from the neglected census of 1831 for Lower Canada are used to test the controversial (but still dominant) traditional “poor French farmers” explanation for a prolonged economic crisis. The new evidence shows that French-speaking areas were equally as productive as English-speaking areas, something that upturns the established consensus and reinforces the minority viewpoint that culture had little to do with the crisis. Using a broad range of controls, the researchers find that this conclusion is robust and that other variables such as settlement recency, environment, and economic structure were much more significant determinants of TFP. These results warrant the abandonment of the cultural explanation and a shift toward other explanatory channels.  相似文献

Dating is perhaps the most frequently asked question in rock art studies, but still one of the most difficult to answer. However, chronology is vital in order to understand and interpret rock art sites. Unfortunately, attempts at dating the Mikinak site, at Lake Wapizagonke, Quebec, Canada were unsuccessful. But a multi‐instrumental protocol applied to characterize paintings shows that at least three different paint recipes were employed to create the site. These may reflect three different phases of paintings, and that at least three different artists contributed to the production of this site.  相似文献
