While there is a burgeoning literature on the role of ICT in the creation of new forms of social networks, dubbed on-line communities, much less attention has been paid to the complex set of relationships which are emerging between some off-line communities and the internet, and in particular to some of the new spatialities that are emerging as a result of community-based ICT practices. This paper develops this work by focusing on the example of ‘the Deaf community’. In reflecting on the implications of the communication possibilities offered by the internet for the production of Deaf space we begin by outlining the history of development of the off-line Deaf community in the UK and by reflecting on the concept of ‘community’. The paper then goes on to explore how Deaf people are using the internet to communicate with each other and, in doing so, to reflect upon how the internet is contributing to the re-spatialisation and scaling-up of this community while also having other unanticipated effects on Deaf people's mobilities and the space of the Deaf club.  相似文献

ABSTRACT

Following the devastation of the northern Iraqi city of Mosul by the Islamic State (IS), UNESCO launched a project to ‘Revive the Spirit of Mosul’. This article critically reflects on this UNESCO-led project, drawing on 47 interviews with Syrians and Iraqis, as well as documenting the implications of UNESCO’s efforts in earlier (post-)conflict heritage reconstruction projects in the Balkans, Afghanistan and Mali. Specifically, this article focuses on two sites in Mosul, both deliberately destroyed by the IS and both nominated by UNESCO for reconstruction. The data analysed reveal that heritage reconstruction projects, especially in complex (post-)conflict environments such as Iraq, requires ongoing, nuanced and careful engagement with local populations to succeed. Failure to do so leaves both local people and their heritage sites vulnerable to renewed attacks and therefore ultimately undermines UNESCO’s broader mission to foster peace.  相似文献

This paper outlines the first methodology for recording dental enamel hypoplasia in the high‐crowned dentition of modern and archaeological caprine teeth. The method has been developed and trialed on five caprine populations from Orkney (UK); two modern populations (Shetland and North Ronaldsay breeds) and three Neolithic assemblages from the archaeological sites of Knap of Howar, Skara Brae and Holm of Papa Westray. Problems associated with differential tooth wear, as well as the presence of coronal cementum, are discussed, and recommendations are given on the identification and recording of hypoplastic dental defects in caprines.

Poropat, S.F., Martin, S.K., Tosolini, A.-M.P., Wagstaff, B.E, Bean, L.B., Kear, B.P., Vickers-Rich, P. &; Rich, T.H., May 2018. Early Cretaceous polar biotas of Victoria, southeastern Australia—an overview of research to date. Alcheringa 42, 158–230. ISSN 0311-5518.

Although Cretaceous fossils (coal excluded) from Victoria, Australia, were first reported in the 1850s, it was not until the 1950s that detailed studies of these fossils were undertaken. Numerous fossil localities have been identified in Victoria since the 1960s, including the Koonwarra Fossil Bed (Strzelecki Group) near Leongatha, the Dinosaur Cove and Eric the Red West sites (Otway Group) at Cape Otway, and the Flat Rocks site (Strzelecki Group) near Cape Paterson. Systematic exploration over the past five decades has resulted in the collection of thousands of fossils representing various plants, invertebrates and vertebrates. Some of the best-preserved and most diverse Hauterivian–Barremian floral assemblages in Australia derive from outcrops of the lower Strzelecki Group in the Gippsland Basin. The slightly younger Koonwarra Fossil Bed (Aptian) is a Konservat-Lagerstätte that also preserves abundant plants, including one of the oldest known flowers. In addition, insects, crustaceans (including the only syncaridans known from Australia between the Triassic and the present), arachnids (including Australia’s only known opilione), the stratigraphically youngest xiphosurans from Australia, bryozoans, unionoid molluscs and a rich assemblage of actinopterygian fish are known from the Koonwarra Fossil Bed. The oldest known—and only Mesozoic—fossil feathers from the Australian continent constitute the only evidence for tetrapods at Koonwarra. By contrast, the Barremian–Aptian-aged deposits at the Flat Rocks site, and the Aptian–Albian-aged strata at the Dinosaur Cove and Eric the Red West sites, are all dominated by tetrapod fossils, with actinopterygians and dipnoans relatively rare. Small ornithopod (=basal neornithischian) dinosaurs are numerically common, known from four partial skeletons and a multitude of isolated bones. Aquatic meiolaniform turtles constitute another prominent faunal element, represented by numerous isolated bones and articulated carapaces and plastrons. More than 50 specimens—mostly lower jaws—evince a high diversity of mammals, including monotremes, a multituberculate and several enigmatic ausktribosphenids. Relatively minor components of these fossil assemblages are diverse theropods (including birds), rare ankylosaurs and ceratopsians, pterosaurs, non-marine plesiosaurs and a lepidosaur. In the older strata of the upper Strzelecki Group, temnospondyl amphibians—the youngest known worldwide—are a conspicuous component of the fauna, whereas crocodylomorphs appear to be present only in up-sequence deposits of the Otway Group. Invertebrates are uncommon, although decapod crustaceans and unionoid bivalves have been described. Collectively, the Early Cretaceous biota of Victoria provides insights into a unique Mesozoic high-latitude palaeoenvironment and elucidates both palaeoclimatic and palaeobiogeographic changes throughout more than 25 million years of geological time.

ABSTRACT

Palaeoparasitological investigation was conducted on a first set of samples from 13 sacrificed domestic camelids recovered from the pre-Hispanic Chimú culture site of Huanchaquito-Las Llamas, Peru. The aim was to establish the animals’ gastrointestinal parasite diversity and enlighten on their health status at the time of their death. To this end, 20 samples of coprolites and intestinal contents were analysed to check for the presence of parasite markers, i.e. preserved eggs and oocysts. Microscopic examinations revealed the presence of five taxa of helminths and protozoans in a majority of the tested animals (61%). Our analysis revealed the presence in some animals of protozoan oocysts belonging to the species Eimeria macusaniensis (phylum Apicomplexa). Our study is the first report of the possible presence of a parasite egg attributed to the order Plagiorchiida (family Fasciolidae) in ancient camelids. This preliminary study shows that there is interesting potential for conducting palaeoparasitological analysis at the site and that such analysis is promising for answering questions about the health status of the Huanchaquito-Las Llamas camelids.  相似文献

ABSTRACT

Faced with an increasingly authoritarian and assertive China, the United States (US) under President Trump administration’s has embarked on a course toward a more openly competitive US–China relationship. However, the debate in Australia has viewed the new era of US-Sino strategic competition mostly negatively. Indeed, arguments have been made for a need to ‘radically’ rethink Australia’s defence policy in order to prepare for a ‘post-US-led’ regional order. For some analysts, Canberra has even no other choice than to adopt a strategy of ‘armed neutrality’ to deal with an emerging China-dominated regional order and a declining US, confused and unwilling to defend its allies. In contrast, this article argues that on balance Trump’s course correction on China is positive for Australia as the US is likely to maintain its robust engagement in the Indo-Pacific. While the president’s inconsistencies partly undermine US declaratory statements in regards to greater competition with China, a bipartisan consensus is likely to continue to shift US policy in this direction. While greater US-Sino competition requires Australia to assume greater responsibilities for regional security, radical changes to its defence policy and security alignment are not needed.  相似文献

Historians and sociologists of Europe have explored the role of events, incidents, and scandals in time. Yet, historians of India have less explored the study of scandal. The reason for this is the relative dominance of certain topics – colonial subjugation, the nationalist movement, independence, and partition of the subcontinent – among historians of India. However, scandals in particular – and events and incidents more generally – offer scholars insight and utility into particular times and places.  相似文献
