Generation and Place of Residence in the Symbolic and Lived Identity of Maltese in Sydney,Australia     

Gordon Waitt  Rebecca M. Galea  Patrick Rawstorne 《The Australian geographer》2001,32(1):77-91

Maltese symbolic and lived identities are examined to explore the changes that occur in cultural identity between generations and place of residence within metropolitan Sydney. The results are employed to problematise Sandberg's straight-line theory, that is, that ethnic identity will decline with each successive generation. Our results, exploring ethnic identity in both its symbolic and lived-experience forms, confirm arguments that global cities are not homogeneous territories, as implied by Sandberg, but rather sites of cultural difference. The results suggest that, regardless of place of residence or generation, the symbolic Maltese identities remain similar, combating the old, naive assimilationist assumption that all immigrants would quickly abandon their ethnic identity, and favouring arguments supporting hybrid identities. Similarly, results for Maltese identity as lived experience suggest that their Maltese identity is less important only for those second-generation Maltese living in census collection districts with less than 10 per cent of the population born in Malta.  相似文献   

Genetic relationships between swamp microenvironment and sulfur distribution of the Late Paleozoic coals in North China     

汤达祯  杨起  周春光  康西栋  刘大锰  黄文辉 《中国科学D辑(英文版)》2001,44(6):555-565

The genetic relationships between microenvironment of the Late Paleozoic peat-forming swamp and the sulfur contents of coal in North China have been studied by using coal-facies parameters involving gelification degree, tissue preservation index, vegetation index, transportation index, groundwater influence index, water medium indicator and swamp type index, etc. Among the various controlling factors of swamp microenvironment, swamp water medium elaborates a dominant action to sulfur accumulation in the marine-influenced coals; while coal-forming plant type, hydrodynamic state and water covering depth are more important to sulfur accumulation in the fresh water-influenced coals. Geological fractionation of sulfur isotopes reflects that sulfur accumulation experienced multi-stages evolution. Pyrite sulfurs formed earlier than organic sulfur and the sulfur isotopic δ³⁴S_p shows lower values than organic sulfur isotopic δ³⁴S_o. In the brine-influenced coals, sulfur accumulation processed relatively a long time span, the distribution of sulfur isotopes dispersed, and the coals are provided with high sulfur contents. In the fresh-water-influenced coals, sulfur accumulation occurred mainly at the syngenetic-penesyngenetic stage and the early diagenetic stage, and the total sulfur is lower and mainly composed of organic sulfur.  相似文献

The Demise of Place Equity in Sydney's Economic Development Planning     

Glen H. Searle 《The Australian geographer》2002,33(3):317-336

The role of planning in Sydney's economic development since the mid-1970s is explored, focusing on its role in reducing spatial disparities across the region. Planning policies during the period of each State government--Labor (1976-88), Liberal-National (1988-95) and Labor (1995-present)--are reviewed. The paper analyses a hierarchy of factors underlying the relative failure of policies to lessen disparities, notably intra-government failure to produce effective policies, the influence of prevailing ideology, local institutions and political culture, and the wider context of globalisation and the mode of capitalist accumulation. Each of these has been significant in limiting planning's role in addressing uneven development across the region.  相似文献

通过吐哈盆地煤的低温排烃模拟实验及源岩与原油之间组分分析,发现煤与泥岩的排烃作用存在明显差异。煤成油在排驱过程中,由于地质色层作用使组分分布特征产生了明显变化而难以与母源对比。煤成油的油源对比不适宜引用以往＂油一源必然相似＂的原则。  相似文献   

A study in early diagenesis: Biomarker composition of a suite of immature coals and coaly shales     

Maowen Li  R.B. Johns  Bowen Mei 《Organic Geochemistry》1990,16(4-6)

A suite of samples from the Funan Mine, N.E. China, has allowed a comparison to be made between hydrocarbon-rich coals and coaly shales. These are immature coals and the known geological history suggests that they have experienced only a mild geothermal history. Analyses of the di- and sesquiterpenoid components show that compounds based on the kaurane skeleton are absent unlike Australian brown coals; and the diterpenes isopimarane, pimarane and 16α (H)-phyllocladane relate to a different community of higher plants such as Pinaceae and Taxodiaceae from those recognized in Australian brown coals. A consideration of geochimical parameters and biomarker composition leads to the conclusion that the geolipid concentrations in the sample suite are environmentally determined. It is concluded, therefore, that 22R-17β (H),21β (H)-bishomohopanoic acid and the 22R-17α (H),21β (H)-homohopane, both predominant components in their respective classes, are derived from different sources. Labdanic acids have been identified in these coals. They are likely to be derived from resin constituents of the coal and not from microbial biomass. They could potentially be developed as a maturation parameter. Cis and trans isomers of a triaromatic hydrocarbon based on the oleanane skeleton which has been previously identified in Victorian brown coal are present in the Funan coals. The more oxidizing the environment the less advanced is the isomerization of cis to trans and again the environment of deposition is the controlling factor. This study emphasizes the importance of understanding pathways of early diagenesis for the interpretation of data derived from more mature samples.  相似文献

Resident action groups in Sydney: people power or rat‐bags?     

Lauren N. Costello  Kevin M. Dunn 《The Australian geographer》1994,25(1):61-76

This paper presents an analysis of a neglected area of study by geographers; that of resident action groups. During the 1980s there has been a significant increase in the number of resident action groups throughout Sydney. Resident activism has influenced local planning processes, the location of noxious facilities and subsequent urban form. This has initiated important reactions by government at both the local and State levels. Urban collective activisms have been hypothesised as single‐issue, self‐serving nimby groups. However, RAGs are also empowering forces, in which women and men are introduced to the political structures and become engaged in protest and resistance that can challenge the social and spatial order. RAGs can, either singularly or cumulatively, force a re‐aligning of existing power relations, and they can necessitate changed modes of governance (or govern‐mentality).  相似文献   

Discussion of “Geomechanical modeling of the nucleation process of Australia's 1989 M5.6 Newcastle earthquake” by C.D. Klose [Earth Planet. Sci. Lett. 256 (2007) 547–553]     

C.D. Quinn  R.A. Glen  C.F.K. Diessel 《Earth and Planetary Science Letters》2008,269(1-2):296-302

On the basis of a numerical simulation, Klose [Earth Planet. Sci. Lett. 256: 547–553 (2007)] proposed that the M_W = 5.2–5.6 earthquake that nucleated beneath Newcastle (New South Wales, Australia) at 10.30 AM December 28, 1989 (AEST), was the result of 200yr of coal mining in the region. We argue here that Klose's [Earth Planet. Sci. Lett. 256: 547–553 (2007)] ultimate conclusion is not supported by his own model or by available geological and seismic data. In particular, the 1989 Newcastle earthquake was not anomalous with respect to regional seismic activity.  相似文献   

Making in the City: disjunctures between public discourse and urban policy     

Kylie Budge 《The Australian geographer》2019,50(2):185-199

Creative cities contribute much to the cultural economies and identities of a nation, shaping imagination and talent, and contributing to the sense of livability and place. Artists, designers, crafters, tinkerers, and even small-scale manufacturers are at the heart of urban rejuvenation in cities such as Brooklyn in New York, and Newcastle and Melbourne in Australia. Increasingly this activity is referred to in the public realm via the media, including social media, through the all-encompassing term ‘making’. Yet in much public policy, this activity is framed through previously held notions: artists, culture, and the precincts associated with this life. I explore this disjuncture by focusing on a case study of Australia’s largest city, Sydney, to interrogate the current schism between public and policy discourse. I share findings about the role of discourse, community consultation, and timing in policy development to argue that valuing making in cities requires commitment to continual community consultation to ensure policy currency, with makers as key stakeholders in this dialogue. Furthermore, the intersection of policy domains is required to prevent isolating making into one policy area. I highlight implications for the imagining of creative cities.  相似文献
