The practice of participatory planning at Mapoon Aboriginal settlement: Towards community control, ownership and autonomy

The practice of participatory planning in discrete Indigenous settlements has been established since the early 1990s. In addition to technical and economic goals, participatory planning also seeks community development outcomes, including community control, ownership and autonomy. This paper presents an evaluation of one such planning project, conducted at Mapoon in 1995. The Plan successfully improved physical infrastructure and housing, but had mixed success in terms of community development. Despite various efforts to follow participatory processes, the Plan was essentially a passing event, community control progressively diminished after its completion, and outcomes fell short of notions of ownership and autonomy. This suggests some misunderstandings between the practice of participatory planning and the workings of governance.

Regional renaissance? New forms of governance in nonmetropolitan Australia

Since the Second World War, Australian governments have adopted various approaches to governing nonmetropolitan Australia. The authors profile three distinct approaches to governance characterised as (1) state-centred regionalism; (2) new localism; and (3) new forms of multifaceted regionalism. Although recent policy initiatives have been justified by the argument that the region is the most suitable scale for planning and development in nonmetropolitan Australia, in practice the institutional landscape is a hybrid of overlapping local, regional, and national scales of action. The authors compare this new, multifaceted, regionalism with the so-called 'new regionalism currently being promoted in Western Europe and North America. It is argued that new regionalism differs in quite important ways from the regionalism currently being fostered in Australia. In Australia, the centrality of sustainability principles, and the attempt to foster interdependence amongst stakeholders from the state, market, and civil society, have produced a layer of networked governance that is different from that overseas. It is argued that there is a triple bottom-line 'promise' in the Australian approach which differs from the Western Europe/North American model, and which has the potential to deliver enhanced economic, social, and environmental outcomes.

A Future for the Past: Rethinking the Garden Suburb

In the quest for sustainability in affluent urban societies we could do much worse than to look again at what the garden suburb attempted to do. Brentham garden suburb in West London, which has recently celebrated its centenary, is a case in point.

Translating policy: Power and action in Australia's country towns

Controversies In its present condition, rural Australia is characterised by a discourse of decline that sees country towns and regions as places of demoralisation and despair. From a Foucauldian governmentality perspective, those who live in these spaces are not so much 'powerless' to the demands of urban-based governments and global capital, as rendered governable according to the socio-political ambitions of late capitalism. While important insights have been derived from such analyses, it is argued in this paper that excessive attention is often paid to the power of the state with little concern for the various ways in which local people engage with, and transform the strategies and effects of state power. Rather than utilising the concept of resistance to make sense of these interactions, a sociology of translation is adopted from the Actor Network Theory literature. Applied to two case examples, it shows how governmental policies and programmes are frequently the outcome of the interactions and negotiations that take place between all those enrolled in the actor-network.

Robo1 regulates the development of major axon tracts and interneuron migration in the forebrain

The Slit genes encode secreted ligands that regulate axon branching, commissural axon pathfinding and neuronal migration. The principal identified receptor for Slit is Robo ( Roundabout in Drosophila). To investigate Slit signalling in forebrain development, we generated Robo1 knockout mice by targeted deletion of exon 5 of the Robo1 gene. Homozygote knockout mice died at birth, but prenatally displayed major defects in axon pathfinding and cortical interneuron migration. Axon pathfinding defects included dysgenesis of the corpus callosum and hippocampal commissure, and abnormalities in corticothalamic and thalamocortical targeting. Slit2 and Slit1/2 double mutants display malformations in callosal development, and in corticothalamic and thalamocortical targeting, as well as optic tract defects. In these animals, corticothalamic axons form large fasciculated bundles that aberrantly cross the midline at the level of the hippocampal and anterior commissures, and more caudally at the medial preoptic area. Such phenotypes of corticothalamic targeting were not observed in Robo1 knockout mice but, instead, both corticothalamic and thalamocortical axons aberrantly arrived at their respective targets at least 1 day earlier than controls. By contrast, in Slit mutants, fewer thalamic axons actually arrive in the cortex during development. Finally, significantly more interneurons ( up to twice as many at E12.5 and E15.5) migrated into the cortex of Robo1 knockout mice, particularly in both rostral and parietal regions, but not caudal cortex. These results indicate that Robo1 mutants have distinct phenotypes, some of which are different from those described in Slit mutants, suggesting that additional ligands, receptors or receptor partners are likely to be involved in Slit/Robo signalling.

Conjugation of an antibody to cross-linked fibrin for targeted delivery of anti-restenotic drugs

There is an urgent need to treat restenosis, a major complication of the treatment of arteries blocked by atherosclerotic plaque, using local delivery techniques. We observed that cross-linked fibrin (XLF) is deposited at the site of surgical injury of arteries. An antibody to XLF, conjugated to anti-restenotic agents, should deliver the drugs directly and only to the site of injury. An anti-XLF antibody (H93.7C.1D2/48; 1D2) was conjugated to heparin (using N-succinimidyl 3-(2-pyridyldithio)-propionate), low molecular weight heparin (LMWH) (adipic acid dihydrazide) and rapamycin (1-ethyl-3-(3-dimethylaminopropyl)carbodiimide/N-hydroxysuccinimide), and the conjugates purified and tested for activity before use in vivo. Rabbits had their right carotid arteries de-endothelialised and then given a bolus of 1D2-heparin, 1D2-LMWH or 1D2-rapamycin conjugate or controls of saline, heparin, LMWH, rapamycin or 1D2 (+/-heparin bolus) and sacrificed after 2 or 4 weeks (12 groups, n=6/group). Rabbits given any of the conjugates had minimal neointimal development in injured arteries, with up to 59% fewer neointimal cells than those given control drugs. Rabbits given 1D2-heparin or 1D2-LMWH had an increased or insignificant reduction in luminal area, with positive remodelling, while the medial and total arterial areas of rabbits given 1D2-rapamycin were not affected by injury. Arteries exposed to 1D2-heparin or 1D2-rapamycin had more endothelial cells than rabbits given control drugs. Thus, XLF-antibodies can site-deliver anti-restenotic agents to injured areas of the artery wall, where the conjugates can influence remodelling, re-endothelialisation and neointimal cell density, with reduced neointimal formation.

Regulation of Amh during sex determination in chickens: Sox gene expression in male and female gonads

During mammalian sexual development, the SOX9 transcription factor up-regulates expression of the gene encoding anti-Mullerian hormone (AMH), but in chickens, Sox9 gene expression reportedly occurs after the onset of Amh expression. Here, we examined expression of the related gene Sox8 in chicken embryonic gonads during the sex-determining period. We found that cSox8 is expressed at similar levels in both sexes at embryonic day 6 and 7, and only at the anterior tip of the gonad, suggesting that SOX8 is not responsible for the sex-specific increase in cAmh gene expression at these stages. We also found that several other chicken Sox genes (cSox3, cSox4 and cSox11) are expressed in embryonic gonads, but at similar levels in both sexes. Our data suggest that the molecular mechanisms involved in the regulation of Amh genes of mouse and chicken are not conserved, despite similar patterns of Amh expression in both species.

Neural progenitor number is regulated by nuclear factor-kappa B p65 and p50 subunit-dependent proliferation rather than cell survival

The number of cells generated by a proliferating stem or precursor cell can be influenced both by proliferation and by the degree of cell death/survival of the progeny generated. In this study, the extent to which cell survival controls progenitor number was examined by comparing the growth characteristics of neurosphere cultures derived from mice lacking genes for the death inducing Bcl-2 homologue Hara Kiri (Hrk), apoptosis-associated protein 1 (Apaf1), or the prosurvival nuclear factor-kappa B (NF kappa B) subunits p65, p50, or c-rel. We found no evidence that Hrk or Apaf1, and by inference the mitochondrial cell death pathway, are involved in regulating the number of neurosphere-derived progeny. However, we identified the p65p50 NF kappa B dimer as being required for the normal growth and expansion of neurosphere cultures. Genetic loss of both p65 and p50 NF kappa B subunits resulted in a reduced number of progeny but an increased proportion of neurons. No effect on cell survival was observed. This suggests that the number and fate of neural progenitor cells are more strongly regulated by cell cycle control than survival. (c) 2005 Wiley-Liss, Inc.

Reconceptualising social sustainability in urban development

Although the social dimension is often cited as the third leg of triple bottom line sustainability, there is at present general agreement on the difficulty of saying just what social sustainability is and how it can be related to enivironmental sustainability. This paper proposes that a sociotechnical understanding of the relationship beween human behaviour and technical developments provides a way of making the social dimension accessible to engineers, designers and developers. We draw on early work in master planned urban developments to show how a sociotechnical model, married to a life cycle assessment approach can help us understand and design for effective and efficient implementation of sustainability systems

Social inclusion, new regionalism and associational governance: The Queensland experience

In recent years there has been a resurgence of decentralized social governance concerned with the spatial dimensions of disadvantage. This article examines aspects of this resurgence in the Australian state of Queensland where, after the hasty birth of 'place management' in response to the rise of 'Hansonism', a plethora of 'joined-up' policy initiatives were undertaken in relation to the regional dimensions of poverty. We propose that these trends reflect in part new ways of thinking about the spatial aspects of disadvantage which have emerged in recent years and which have the potential to take regional policy beyond the narrow confines imposed by neoliberal economic orthodoxy. These new ways of thinking have arisen in social policy through the refraining of disadvantage in terms of social exclusion and in regional economic policy through the influence of the so-called 'new regionalism'. The article shows how together these bodies of theory point us towards a new model of 'associational governance'. The article reviews recent Queensland experience and indicates those features of 'associational governance' which have become characteristic of locality-based social policy ideas in Queensland. 'Joined-up' and regional policy aspirations of the Queensland State government have shown the influence of these new approaches. The political and policy sustainability of these trends, however, is uncertain. The lingering shadow of managerialism and neoliberal policy frameworks remains a significant barrier to the innovation and viability of these approaches. More directly, the inherent limits of the 'local' or 'regional' initiatives in the face of broader national and global factors will significantly constrain the capacity of associational governance systems to deliver positive democratic, social and economic outcomes. The article examines recent Queensland policy refors in light of this complex set of factors and concludes by offering directions for future research and policy development.

Contemporary strategies for rural community development in Australia: a governmentality perspective

Contemporary strategies for rural development in Australia are based upon notions of self-help and bottom-up, community-based initiatives which are said to 'empower' the individual from the imposing structures of government intervention. While such strategies are not entirely new to Australia, they have, it seems, been inadequately theorised to date and are generally regarded, in rather functionalist terms, as indicative of attempts to cut back on public expenditure. Harnessing itself to the 'governmentality' perspective, this paper explores government and 'expert' discourses of rural community development in Queensland and suggests, instead, that these strategies are indicative of an advanced liberal form of rule which seeks to 'govern through community'. With this in mind, three basic research questions are identified as worthy of further exploration; how are the notions of self-governing individuals and communities constructed in political discourse; what political rationalities are used to justify current levels of(non) intervention and finally; what are the discourses, forms and outcomes of empowerment at the local level? The paper concludes by arguing that while the empowering effects of self-help are frequently cited as its greatest virtue, it is not so much control as the added burden of responsibility that is being devolved to local people. Given the emphasis of the governmentality perspective on strategies for 'governing at a distance', however, these conclusions can hardly be unexpected.
