Wired communities in the city: Sydney, Australia

Questions relating to the ability of particular groups in society to access information and communications technologies (ICTs) have become a growing part of the academic and policy literature. The issues raised in this literature have revolved around a number of themes, many of which can be subsumed under concerns about a growing digital divide whereby society is being divided into information rich and information poor sectors. This differentiation can be between particular social groups irrespective of place, or between people in particular places be these large regional areas (e.g. metropolitan versus non-metropolitan) or localities and communities within an urban area. This paper focuses on the existence of a 'digital divide' across the Sydney metropolitan area. Using ABS 2001 census data the paper presents an analysis of computer and internet access and use for clusters of local communities and focuses on how usage differs across communities as differentiated by socio-economic status, household and family status and ethnic background

Urban vulnerability in Sydney: Policy and institutional ambiguities in bushfire protection

Despite the inevitability of the bushfires hazard across the Sydney region, a mismatch exists between reactive technological fixes and proactive social programs which have far-reaching vulnerability and governance consequences. This paper questions the adequacy of current policy and action, revealing contradictions and tensions that expose Sydney's vulnerability and have implications for other Australian cities.

Protease IV production in Pseudomonas aeruginosa from the lungs of adults with cystic fibrosis

Protease IV is important in the pathogenesis of Pseudomonas aeruginosa-induced microbial keratitis, but little is known of its role in cystic fibrosis (CF) lung infection. In this study protease IV production was examined in 43 P. aeruginosa isolates (24 non-clonal and 19 clonal) from the lungs of chronically infected adult patients attending the Royal Prince Alfred Hospital CF Clinic, Sydney, Australia. Overall, 32/43 (74 %) isolates were positive for protease IV protein by Western blotting and 22/43 (51 %) had evidence of active protease IV on gelatin zymography. Clonal strains were 1.6 times more likely than non-clonal strains to produce protease IV [18/19 (95 %) versus 14/24 (58 %), RR=1.6, CI 1.1–2.3, P=0.007] and 3 times more likely to secrete the protein [16/19 (84 %) versus 6/24 (25 %), RR=3.4, CI 1.6–6.9, P
