The Early Cretaceous Otway and Strzelecki Groups exposed on the southern coast of Victoria, Australia, have produced a fauna of dinosaurs that lived within the Antarctic Circle. As many as five or six species of hypsilophodontids numerically dominate the collections from there, but the rarer and more fragmentary theropod remains suggest a surprising diversity of carnivorous dinosaurs. A possible surangular and an isolated vertebra have characters considered diagnostic for Late Cretaceous oviraptorosaurs of the Northern Hemisphere. Other fossils suggest the presence of ornithomimosaurs, dromaeosaurids and neoceratopsians, and with the possible oviraptorosaur remains, challenge the widespread assumption that these animals originated on the northern continents. 相似文献

Historically, a common technique used to assess a community's ability to support various business activities has been demand-threshold estimation. The concept of a demand threshold has been applied at the community level by estimating a relationship between community population and the number of establishments of a particular kind in the community. The approach taken in this research incorporates a spatial dimension (community urban proximity) in addition to community population to estimate demand thresholds. Using a count data technique, demand thresholds are estimated for 27 different business activities found in 584 rural Saskatchewan communities in 1990. Both population and urban proximity are found to be important explanatory variables. 相似文献

Drawing upon Littler and Naidoo's ‘white past, multicultural present’ alignment, this article examines English newspaper coverage of two ‘British’ events held in 2012 (the Diamond Jubilee and the London Olympic Games). In light of recent work on English nationalism, national identity and multiculturalism, this article argues that representations of Britain oscillated between lamentations for an English/British past – marred by decline – and a present that, while being portrayed as both confident and progressive, was beset by latent anxieties. In doing so, ‘past’ reflections of England/Britain were presented as a ‘safe’ and legitimate source of belonging that had subsequently been lost and undermined amidst the diversity of the ‘present’. As a result, feelings of discontent, anxiety and nostalgia were dialectically constructed alongside ‘traditional’ understandings of England/Britain. Indeed, this draws attention to the ways in which particular ‘versions’ of the past are engaged with and the impact that this can have on discussions related to multiculturalism and the multiethnic history of England/Britain. 相似文献

This article explores the relationship between language and political possibility. It is argued that John Howard's language from 11 September 2001 to mid 2003 helped to enable the ‘War on Terror’ in an Australian context in three principal ways. Firstly, through contingent and contestable constructions of Australia, the world and their relationship, Howard's language made interventionism conceivable. Secondly, emphasising shared values, mateship and mutual sacrifice in war, Howard embedded his foreign policy discourse in the cultural terrain of ‘mainstream Australia’, specifically framing a foreign policy discourse that was communicable to ‘battlers’ and disillusioned ‘Hansonites’. Thirdly, positioning alternatives as ‘un-Australian’, Howard's language was particularly coercive, silencing potential oppositional voices. 相似文献
