The thesis is an explanation of the development of pre-school children's services (infant welfare, kindergartens and child care) at local government level in Victoria. The critical framework of analysis focuses on three dimensions of public policy: 1) the socio-historical environment; 2) the political processes involved in the development of the specific children's service; and 3) the major individuals and groups that exerted pressure for children's service, The argument is threefold. Firstly it is argued that the political environment of children's services has been dominated by the practice of separate spheres of public and private, in which the care of children is primarily the role of women. Secondly, it is argued that the political processes surrounding the development of local children's services have involved all levels of government in what is termed a local state. Thirdly, it is argued that the development of these children's services in local government has resulted mainly from the work of women both individually and collectively. Since the three services of infant welfare, kindergartens and child care all became a normal function of children's services at different times, the circumstances that surrounded each development exhibited different aspects of the three major arguments. The periodisation is broken into four phases: 1) the establishment of local government with no children's services in the nineteenth century; 2) the establishment of infant welfare services in local government in the early part of the twentieth century; 3) the incorporation of kindergartens into local government after the second world war; and 4) the incorporation of child care into local government in the 1970s and 1980s. The thesis concludes by arguing that the existence of children's services in local government in Victoria is testimony to the remarkable work of those women who have pursued the issue both individually and collectively. It has been the identification of children's services as a women's issue in Australian politics that has enabled women's groups at different times to influence the policy makers in diverse ways. However, while the establishment of children's services as a legitimate political concern brings the matter onto the public agenda, the separate spheres still remains a contested issue in the public policies of children's services.

An atomic force microscope was used to measure the forces acting between two polystyrene latex spheres in aqueous media. The results show an electrostatic repulsion at large separations which is overtaken by an attractive “hook” that pulls the two spheres into contact from a considerable range (20−400 nm), much larger than could be expected for a van der Waals attraction. The range of operation of this attraction varies from one experiment to another and is not correlated with electrolyte concentration. However, the range is found to decrease significantly when the level of dissolved gas in the water is reduced.

Uniform hydrangea-like multi-scale carbon hollow submicron spheres (HCSSg) are fabricated by a simple hydrothermal method using glucose as carbon source and fibrous silicon dioxides spheres as shape guide. Structure characterization suggests that petal-like partially graphitized carbon nanosheets with the thickness of about 10 nm arranged in three dimensions (3D) to form the hydrangea-like hollow spheres (size ranging from 250 to 500 nm) with mesoporous channels, which can be conducive to be a high specific surface area (934 m2 g-1) and bulk density (0.87 cm g-3), hierarchical pores structure with good conductivity. As a result, the HCSSg has been demonstrated to be a supercapacitor electrode material with high gravimetric (386 F g-1 at 0.2 A g-1) and outstanding volumetric (335 F cm-3) capacitance, good rate capability and cycling stability with 94% capacitance retention after 5000 cycles in aqueous electrolytes, thus suggesting its application potential.

This study assessed the influence of diet composition on hyaline sphere (HS) development in auricularia larvae of the sandfish, Holothuria scabra, and the subsequent relationships between the presence and size of hyaline spheres and competency through settlement and early juvenile performance. Two-day old larvae were fed one of three commercially available micro-algae diets that varied in their nutrient compositions: (1) Isochrysis sp. (Haptophyceae); (2) Pavlova sp. (Haptophyceae); and (3) Thalassiosira weissflogii (Bacillariophyceae) or a ternary combination of the three. There were positive significant correlations between HS development in late auriculariae on days 10, 11, 12 and 13 post-fertilisation, and the proportion of competent doliolariae on day 15, post-settlement size (day 21) and post-settlement survival (day 25). The dietary components that most strongly influenced these relationships were carbohydrates and the n-3 polyunsaturated fatty acids arachidonic acid (ARA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Our result confirm the strong relationship between HS formation in late auriculariae of sandfish and subsequent larval competency through settlement. As such, the presence and size of HS is a reliable indicator of subsequent performance for sandfish. Given that HS development was influenced by the nutrients available to sandfish auriculariae, there is clear opportunity for development of more appropriate diets for hatchery culture of this species that will improve HS formation and larval performance supporting improved hatchery production. Statement of relevance Our results have confirmed that for sandfish larvae, the presence and size of HS at the end of the auricularia stage, is indeed a reliable indicator of subsequent performance. Our results have also confirmed that HS formation and size is significantly influenced by the nutrient composition of the auricularia diet, and that there are significant positive correlations between HS formation and dietary levels of carbohydrate, EPA:DHA and EPA:ARA ratios. This information provides a strong basis for development of more appropriate diets for sandfish larvae that will improve HS formation and larval performance during hatchery culture and in turn improve hatchery production of this species.

Human rights law has traditionally focused on the obligations of states in fulfilment of human rights - how a state-focused approach fits in a world where social services are frequently privatised or contracted out - examples of social service provision, health, education and prisons, and inquiries into the obligations of the state and the private operators in relation to these services - private providers of social services have certain human rights obligations within their respective spheres of activity - the state retains an obligation to guarantee the protection and realisation of human rights of everyone under its jurisdiction, regardless of the character of the service provider.

The successive Howard Governments sought not only to make foreign policy in response to new regional and global agendas, but to respond to and to seek to manage new forms of electoral challenge with new forms of nationalism. This has resulted in a set of important departures from the major Liberal tradition in international affairs, the claim to a realist approach to foreign policy, and has led to the need to manage the consequences of those departures. The boundary that realism sought to draw between the domestic and international politics, as the spheres of values and interests respectively, became increasingly blurred. In relations with the Asian region the expression of strong domestic (nationalist and internationalist) agendas led initially to distancing from Asian engagement. However, from 2002, a more realist-focused external policy led to new forms of state to state re-engagement in pursuit of national interests. In the commitment to military operations in Iraq, the Anzac legend is interpreted to supply nationalist legitimation which would not normally be required for wars fought for realist (i.e. defensive) reasons. A future Liberal prime minister would lack Howard's touch here. In the debate in the Liberal Party over defence doctrine, an attempt by the Defence Minister to reformulate the realist doctrine of Defence of Australia into an expeditionary construct was rejected.

In her book The Reluctant Modernism of Hannah Arendt (2000) Seyla Benhabib uses the concept of an ‘alternative genealogy of modernity’ to help her both to understand Arendt’s political philosophy and to rethink the potential for civil society to become a progressive political force at the beginning of the twenty first century. The idea of an alternative genealogy of modernity refers to a heterogeneity of social and political forms, spaces and acts that might be used to remap and redefine a modernity whose dominant topology has been shaped by the binary division between so-called public and private spheres. Alternative modernities have already been elaborated and explored from a range of different perspectives including feminist and postcolonial ones: for example, in Rita Felski’s Gender of Modernity (1995) and Dipesh Chakrabarty’s Provincialising Europe (2000). In this paper I want to elaborate upon the idea of an alternative genealogy of modernity from my perspective as a dancer. Thinking through the sociality of art and, more specifically, of some historical dance-making practices can make visible alternative spaces and processes of the (potentially) political. In the West, the modes of art-making form part of an as yet not fully explored arena of the social and of social practices. Modernist and Romantic ideologies have tended to preclude attention to the specific sociabilities of art-making. On the one hand Modernist ideology and art discourses have promoted the idea of an art work’s ‘autonomy’: its radical separation from the social relationships, the bodies and the conditions of its making. On the other hand Romantic ideology, still pervasive in popular conceptions of art practices, construes creation as interiority and individualistic expression. Socialist feminist and Marxist discussions of art have emphasized the social conditions of art-making but these have tended to be concerned with the social inequalities instituted within the public/private split rather than seeking to destabilize that division itself by posing questions of differences within the social. In my discussion below I draw on aspects of early modern dance practice and creation in taking up Benhabib’s concern to mobilise an alternative genealogy of modernity towards a renewal and reactivation of civic life. This project involves unsettling clear distinctions between the so-called ‘public’ and ‘private’ but, at the same time, as Benhabib cautions ‘the binarity of public and private spheres must be reconstructed and not merely rejected’.

This article queries the relatively recent adoption of the term 'stakeholder', borrowed from the UK political and the US business management spheres, in public relations academic writing. The article concludes that these spheres use the term in a normative or ideological manner that has worrying implications. The term frames people as having a pre-existing relationship with the governments or business organisations which name them as such. This process of incorporation prejudges and potentially obscures the real relations of groups of people vis-à-vis governments and business organisations which they may wish to have nothing to do with. An argument is mounted for the defence of the term 'publics'. It is pointed out that a key originator of stakeholder theory opposes the notion of 'publics' as closer to a notion of an uncontrolled audience. The article argues that the notion of 'publics' is more fitting than the notion of 'stakeholders' if public relations is about acknowledging this uncontrollability, and to do with advising organisations about their positioning in the democratic milieu. On the other hand, the notion 'stakeholders' may be the right one if public relations is simply aimed at immediately shaping people's behaviour, irrespective of longer term and wider political implications.

Historically, Australia’s interests in the Middle East related primarily to its role in the Commonwealth imperial defence system which resulted in the deployment of Australian forces in the Middle East during both the First and Second World Wars. Similarly, the current involvement of Australian troops in Iraq and Afghanistan is driven by the country’s strategic alliance with the United States. However, Australia’s current involvement reflects a multifaceted relationship that spans economic, political and strategic spheres. Yet it is at the level of cultural and civilisational contacts that this relationship appears at its most vulnerable. This paper argues that a deeper understanding of this cultural dimension combined with a broader emphasis on good governance and human rights would be conducive to more robust ties in the longer term.

This article examines specific issues encountered in various areas of Chinese teaching in Australia. These issues are linked to the spheres of language planning as acquisition and as recovery and language planning as retention (Lo Bianco, 10.1007/s10993-006-9042-3). Specifically relevant to Chinese in Australia is its current prominence in formally declared national language policy, its changing status over time and its similarities and differences with Chinese in the United States (Wang, 10.1007/s10993-006-9043-2). The internationalization of education, and its commodification, has in recent years led to a major expansion in the range of offerings in Chinese in Australia, now catering to growing, and in some institutions to numerically dominant, groupings of native speakers with radically different language and academic needs from the traditional clientele of tertiary and school Chinese programs.

Research into how the 'type' of sibling death impacts surviving siblings at a social level was conducted using a semi-structured interview format with 25 bereaved siblings and seven counsellors. The results indicated that in cases where a sibling's death had a greater impact within public spheres, the young adult was more likely to receive beneficial social support than young adults associated with 'private' death examples. The paper concludes by outlining how individuals can provide effective support for bereaved young adults, as well as avoid unhelpful support behaviours.
