'Royal science' and civil war in Sri Lanka : a comment on S. Goonatilake

In highlighting the relationship between the production of knowledge, the administration of government and the formation of subject–citizens in colonial systems, post-colonialism has arguably found its most fertile field of inquiry and revision in South Asia. The reasons for this are complex and relate, in part, to the nature of both colonial administration and the colonised civilisations to be found in the region, as well as to the nature of the different independence movements—many of these persisting well beyond the formal grants of independence in the late 1940s. Also important is the emerging post-colonial middle class, its transnational interconnections comprising inter alia extensive participation in knowledge/information economies, and its ‘organic intellectuals’ (Gramsci 1971) whose work represents the interests of their class. In other words, the tremendous insights offered by post-colonial theory into the nature of latent or implicit power relations to be found in forms of knowledge reveal the ongoing complicity of scholarship in government. Post-colonialism, thus, raises the issue of how the nexus of knowledge and power translates into contemporary situations—the post-colonial predicament (Breckenridge and van der Veer 1993).

Spatial ecology of sooty owls in south-eastern Australian coastal forests : implications for forest management and reserve design

We investigated the home-range size and habitat use of eight Sooty Owls (Tyto tenebricosa tenebricosa) in coastal forests in East Gippsland, Victoria, Australia, between November 2006 and January 2008. The size of home-ranges varied widely; based on 95% adaptive kernel estimates, the average size of home-ranges of males was 3025ha (±1194s.d., n=3), whereas that of females was 994ha (±654s.d., n=5). Sooty Owls utilised a broad range of ecological vegetation classes and topographical features for roosting and foraging at a greater scale than previously assumed. There was minimal selection for habitat types based on floristic composition, primarily only avoiding heathlands (for foraging and roosting) and selecting particular dense foliage (rainforest and riparian scrub) for foliage roosting. Two Owls maintained home-ranges close to logged areas, with logging regrowth (<45 years old) being strongly avoided by both individuals. We recommend that the size of individual reserves for Sooty Owls in commercial forests should be increased to more closely resemble the core spatial resource requirements needed by a pair. Reserves should be largest where they feed predominantly on hollow-dependent prey. Most importantly, rather than conservation measures just focussing on the spatial requirements of Sooty Owls, efforts should be directed towards retaining high densities of crucial resources, such as hollow-bearing trees and mammalian prey species throughout the landscape.

Spawning season movements of Macquarie perch (Macquaria australasica) in the Yarra River, Victoria

The Macquarie perch (Macquaria australasica) is a threatened fish species that inhabits rivers and impoundments in south-eastern Australia. Previous studies have shown that Macquarie perch in impoundments exhibit synchronised upstream spawning migrations to shallow, fast-flowing habitats in the lower reaches of inflowing streams. There has been little study of movement behaviours of entirely riverine populations of Macquarie perch despite this being the species’ natural habitat. Here, radio-telemetry is used to test the hypothesis that riverine populations exhibit synchronised migrations during the spawning season. Thirty Macquarie perch in the Yarra River, Victoria, a translocated population outside of the species’ natural range, were radio-tagged before the late spring–early summer spawning season and their movements followed over a 10-month period (May 2011 to February 2012). Tagged fish typically occupied restricted reaches of stream (<450 m). Sixteen of the fish undertook occasional upstream or downstream movements (~250–1000 m) away from their usual locations, particularly associated with large flow variations during the spawning season. There was no evidence of synchronised migratory behaviour or movement of multiple fish to specific locations or habitats during the spawning season. Whilst further research over more years is needed to comprehensively document the spawning-related behaviours of riverine Macquarie perch, our study demonstrates that management of riverine populations of this threatened species cannot necessarily be based on the model of spawning behaviour developed for lacustrine populations.

The politics of public sector change: trends in health and education sector change in South Australia

BACKGROUND: As the changes underpinning the Coordinated Care Trials in South Australia have become more apparent, similarities have emerged between the rationalisation of public schooling in the mid 1980s and the transformation of public health in the 1990s.

OBJECTIVE: This article aims to discuss the evolution of health services in South Australia and help us answer the question of how best to manage our public and private health infrastructure in a changing economic and social context.

DISCUSSION: Both strategies in education and health share common elements of cost cutting, attempts at improving efficiencies, a flirting with the private sector and the attendant risk of reduced quality of services to the public. This situation in both sectors is indicative of a shift in public policy and a growth in the belief that private management of public sector infrastructure can help resolve the funding crises around our education and health systems.
