The palaeobiota from a middle to late Holocene succession in Tom Thumbs Lagoon, N.S.W., Australia, reflects a range of environmental conditions caused by sea-level changes and active estuarine sedimentation. At the base of the succession (~ ?0.4 m AHD) a thin bed, containing molluscs dated at 6.7 ka B.P. by radiocarbon and amino acid racemisation, and foraminifers is indicative of open estuarine conditions. From +0.35 m AHD towards the top of the sequence the charophyte Lamprothamnium succinctum occurs in subrecent deposits. This species is characterised here by statistical measurements, and new characters are described and illustrated. The charophytes record a drop in sea level and the establishment of a lower salinity artificial wetland. The investigation has also established that decalcification in charophytes can be related to acidification produced by the release of organic acids, aggravated after 1928 by anthropogenic pollution. 相似文献

Dermal denticles of two thelodont agnathans, Australolepis seddoni gen. et sp. nov., and a possible nikoliviid gen. et sp. indet. are described from the Gneudna Formation, a marine sequence of interbedded limestone and shale exposed on the eastern edge of the Carnarvon Basin, Western Australia. The age and significance of these new forms are discussed. The Gneudna Formation is Late Devonian, probably early Frasnian, which, if confirmed, makes these the youngest thelodonts known to date. 相似文献

The past few years have seen the rediscovery by political and media commentators of areas in post-industrial Britain characterised as “left behind”. It is rarely acknowledged that this attention to regional inequality has only come about after decades of political neglect and cultural erasure of these areas following deindustrialisation. Current ideas about regional inequality and proposed solutions to it—from the “Red Wall” to “levelling up”—are often conceptualised in ways that in fact continue this neglect, by homogenising these regions and imposing top-down narratives about their demographic and political nature. This paper will contrast these developments with new approaches in several parts of the UK, focusing on democratic localism or “community wealth-building”, which have seen communities in “left behind” areas already addressing regional inequality, and offering their own alternative economic and social models, in a way that presents a more nuanced picture of both class and regional identity. 相似文献

While screen production is notoriously centralised, it is still found outside major media cities where the central problem for actors in these subordinate media cities is how to create sustainable levels of screen production capabilities in circumstances of increasing centralisation and globalisation in media production and its design. This article discusses how the screen production sectors of two subordinate media cities, Brisbane and the Gold Coast, are organised. Each city represents a different pathway for the sustainability of a media sector. The Gold Coast is a production location for globally and nationally dispersed high-budget feature film and TV drama production; while Brisbane is mostly a ‘national production’ location for domestically oriented news, documentary, infotainment and sports programming with a focus on lower budgeted feature filmmaking and occasionally, television drama. These different city pathways are the product of the creative resources and infrastructure evident in each city. 相似文献

Since the 1970s, there has been a fraught yet hopeful Aboriginal cultural resurgence in Australia. An element of this movement has been the establishment of Aboriginal art centres and cultural centres across Australia. Using a comparative approach to Aboriginal art centres, this paper analyses the appearance and characteristics of the more recent Aboriginal cultural centres. The methods used are a review of the literature on Aboriginal art centres, and for the less-researched Aboriginal cultural centres, a case study. This paper posits that cultural centre characteristics are shaped through the formation of alliances made possible by the advent of land rights, an Aboriginal cultural turn amongst Aboriginal and non-Aboriginal people, and changing approaches to regional development. While not themselves a movement that will lead to socio-economic change, these types of arts and heritage projects are aligned to such movements. With a larger scale and more central locations, Aboriginal cultural centres open up opportunities for larger and more diverse alliances, and therefore new opportunities for Aboriginal people’s participation, activism and expression. 相似文献

ABSTRACT The paper implements a methodology for assessing the regional impact of investment grants on foreign direct investment (FDI) location, taking data for U.K. regional policy over the period 1985–2005. Using a Generalized Methods of Moments estimator it finds that each £25 million of grant changes the regional location of about six inward FDI projects. On average, projects have 150 jobs and each job diverted costs £27,500 (1995 prices). It also finds that the size of the area designated for grants has a positive location effect. The effect is small in relation to the overall scale of FDI, which may explain the weak grant effect found in recent plant‐based location studies. 相似文献
