The discovery of a rich assemblage of microfossils from the Neoproterozoic western Officer Basin (Centralian Superbasin) provides a more complete understanding of the biostratigraphy of this Basin. The microfossils are found in Supersequence 1 (~800 Ma) in Western Australia. The assemblages are comprised of acritarchs and cyanobacteria isolated by acid maceration from siliciclastics of the Browne (Madley), Hussar, Kanpa and Steptoe Formations. The distinctive acritarchs Cerebrosphaera buickii, Satka colonialica, Stictosphaeridium sinapticuliferum and Pterospermopsimorpha insolita are of particular interest in the Neoproterozoic. These taxa are found in similar depositional environments in Spitsbergen, Arizona, Canada and Siberia. This evidence, together with lithostratographic correlations, isotope chemostratigraphy, and sequence analysis contributes to the continuing development of Neoproterozoic stratigraphy. 相似文献
The Aboriginal people of the Upper Finke River in central Australia have followed a literacy tradition for over 130 years. When the first Lutheran missionaries arrived, they immediately started to study the local Arandic language and were teaching reading and writing by 1879. Despite this long exposure to literacy and the Lutheran influence on it, the issue of the right orthography for this Arandic language variety is emotionally charged and politically very contested. In this post‐colonial context, orthography has become a sociocultural and symbolic, rather than a phonemic, matter. 相似文献
Song, J., Crasquin, S. & Gong, Y., September 2016. Ostracods of the Late Devonian Frasnian/Famennian transition from western Junggar, Xinjiang, NW China. Alcheringa 41, xxx–xxx. ISSN 0311-5518.
Ostracods are described for the first time from the Late Devonian of western Junggar in Xinjiang, NW China. Fifty-two species belonging to 30 genera are recognized, and seven are new: Arcuaria hebukesarensis sp. nov., Bairdia shaerbuertiensis sp. nov., Cribroconcha honggulelengensis sp. nov., Microchelinella bulongourensis sp. nov., M. hoxtolgayensis sp. nov., Pribylites wulankeshunensis sp. nov. and P. junggarensis sp. nov. The ostracod fauna indicates a probable late Frasnian age for the lower member of the Hongguleleng Formation, and the Frasnian/Famennian boundary may exist in the basal part of the formation. The ostracod assemblages are referable to the Eifelian Mega-Assemblage, incorporating both the palaeocopid and smooth-podocopid associations. The fauna implies deposition in a nearshore–offshore environment during a transgression when the lower member of the Hongguleleng Formation was being deposited in western Junggar.

Studies of transnational families tend to filter understandings of mobility and stasis through a bi-national framework that juxtaposes the movement of migrants across international borders with the immobility of in-place kin within equally static national spaces. This article examines the concept-metaphors of mobility and stasis through the eyes of later-life (over 50 year-old) Western migrants living in Penang, Malaysia and Bali, Indonesia. By treating “in-place” kin as mobile subjects I examine the extent to which the movement of individuals and families within and across a range of national borders affects the lives, concerns and movements of these older, Western migrants and retirees in Southeast Asia. By examining the concept-metaphors from the perspective of these migrants I illustrate the extent to which such people both succumb to yet exceed scholarly imaginings of im/mobility and juxtapositions between mobile selves and immobile others. Migrant thinking about these concept-metaphors, I suggest, complicates an ongoing tendency within the field of transnational family studies to view mobility and stasis as categorical opposites and offers fresh insights into the role and relevance of these concept-metaphors in the lives of Western migrants in Southeast Asia and their transnational relations with teenage and adult children, ageing parents and grandchildren. 相似文献
