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.
The pursuit of "coordination" has been a prominent theme both in local responses to homelessness and in the current incentives in federal housing policy. This article reviews some of the conditions that make coordination important yet difficult to achieve in the homeless area. A variety of approaches for achieving coordination at the local level are reviewed, ranging from point-of-service coordination to system-design. The local examples are drawn from the cities participating in the evaluation of The Robert Wood Johnson and the Department of Housing and Urban Development Homeless Families Program. The questions of effectiveness and future prospects for homeless service coordination are raised. 相似文献
In 2012, Australian cultural heritage practitioners and conservation scientists collaborated on a national underwater cultural heritage (UCH) reburial project, known as the Australian Historic Shipwreck Preservation Project (AHSPP) funded by the Australian Research Council. This resulted in the excavation, documentation and reburial of the ‘at risk’ shipwreck Clarence. Following the excavation, the site and associated artefacts were reburied and subsequently covered by shade cloth and finally, with polyvinyl chloride (PVC) tarpaulins. After completion of the in situ reburial, a number of critical issues were put into sharp relief including: what constitutes the accurate identification of a site as being ‘at risk’; and the implications of ‘rapid reburial’. 相似文献
From humble beginnings in the 1960s, the United Church Women's Fellowship (UCWF) is now viewed as one of the most effective organizations on the island of Ranongga (Western Province, Solomon Islands). This essay considers reasons for the success of women's fellowship in Ranongga, focusing on the distinctive position of women in gendered local and translocal forms of social organization. Far from being isolated from the outside world, Ranonggan women have long been engaged in drawing outsiders into local communities. I explore this theme in narratives of Christian conversion and of the beginning of women's fellowship; I also consider the practices of local and national women's fellowship groups that work to constitute unified communities out of diverse groups of people. My discussion of Ranonggan women's fellowship illustrates local dynamics of community‐making that do not map easily on to dominant models of nation‐states and ethnic groups. I ask whether the UCWF provides an alternative model for thinking about larger‐scale political formations, particularly in the Solomons. This question is especially relevant considering the significant contribution that women's Christian organizations have made in efforts to reconstitute a national community in the context of the ongoing political crisis in Solomon Islands. 相似文献
