"New World Orders shows how texts for children and young people have responded to the cultural, economic, and political movements of the last 15 years. With a focus on international children's text produced between 1988 and 2006, the authors discuss how utopian and dystopian tropes are pressed into service to project possible futures to child readers. The book considers what these texts have to say about globalisation, neocolonialism, environmental issues, pressures on families and communities, and the idea of the posthuman."--BOOK JACKET.

Locust outbreaks provide an abundant, but unpredictable food source for many native species in Australia. For economic reasons, locust control is unavoidable and can affect a considerable area in Eastern Australia. Depending on the pesticide applied, locust control operations may affect birds in treated areas, either directly through intoxication of the predator, or indirectly, through elimination of its prey. As a preliminary step in identifying the potential impact of these operations on native species, the co-occurrence of birds and locust control operations was assessed using GIS mapping techniques. Data from the Birds of Australia New Atlas provided information about species' distribution between latitudes 17 and 37 degree S, and longitudes 136 and 152 degree E. Of the 834 species present in this region, 292 were chosen on the basis of their geographical distribution and occurrence west of the Great Dividing Range. Sightings for each species were mapped using reporting rates and number of observations per half-degree grid cells. Birds were categorised by habitat, distribution, movement and feeding habits and those species reported to consume Orthopterans were noted. APLC locust survey (1987–2000) and spraying data (1977–2002) were analysed and overlapped with soil and vegetation maps obtained from Geoscience Australia and Environment Australia to find significant hotspots for locust occurrence. These maps were then overlayed with bird distributions to identify the species most likely to be in areas of locust presence and spraying operations.

Domesticated dogs threaten the conservation of beach-nesting birds in Australia through disturbance, and destruction of eggs and chicks. Leashing of dogs can improve conservation outcomes, but few dogs are leashed on beaches. We surveyed dog owners to explore their sense of obligation to leash dogs on beaches. Dog owners were more likely to feel obliged to leash their dog when they believed other people expected dogs to be leashed, and when they believed their dog was a threat to wildlife or people. Dog owners were less likely to feel obliged to leash their dog if they considered unleashed dog recreation to be important. Improved compliance may be achieved through community-based approaches to foster social norms for dog control, tailoring information products to emphasize the risk that all unleashed dogs may pose to beach-nesting birds and raising awareness of designated off-leash exercise dog recreation areas.

Although UV vision was first demonstrated in birds in the early 1970s, its function is still unknown. Here we review the evidence for UV vision in birds, discuss the special properties of UV light, lay out in detail hypotheses for the function of UV vision in birds and discuss their plausibility. The main hypotheses are that UV vision functions: (i) in orientation, (ii) in foraging and (iii) in signalling. The first receives support from studies of homing pigeons, but it would be unwise to conclude that orientation is UV's primary function in all birds. It is especially important to test the signalling hypothesis because bird plumage often reflects UV and tests of theories of sexual selection have virtually always assumed that birds perceive plumage ''colours'' as humans do. A priori this assumption is unlikely to be correct, for unlike humans, birds see in the UV, have at least four types of cones and have a system of oil droplets which filters light entering individual cones.

This thesis examines three works: Margaret Atwood's The Robber Bride and Alias Grace, and Angela Carter's Nights at the Circus. All three novels feature female characters that contain elements or myth fragments of mermaids and sirens. The thesis asserts that the images of the mermaid and siren have undergone a gradual process of change, from literal mythical figures, to metaphorical images, and then to figures or myth fragments that reference the original mythical figures. The persistence of these female half-human images points to an underlying rationale that is independent of historical and cultural factors. Using feminist psychoanalytic theoretical frameworks, the thesis identifies the existence of the siren/mermaid myth fragments that are used as a means to construct the category of the 'bad' woman. It then identifies the function that these references serve in the narrative and in the broader context of both Victorian and contemporary societies. The thesis postulates the origin of the mermaid and siren myths as stemming from the ambivalent relationship that the male infant forms with the mother as he develops an identity as an individual. Finally, the thesis discusses the manner in which Atwood and Carter build on this foundation to deconstruct the binary oppositions that disadvantage women and to expand the category of female.

Normally we expect the magic of art to intensify, transfigure and elevate actuality. Touch the Holocaust and the flow is reversed (Clendinnen 1998, p. 185). This dissertation explores the relationships between the second-generation Holocaust writer, the Australian publishing industry and the reading public. It contends that a confluence of elements has made the 'genre' of second-generation Holocaust writing publishable in the late 20th century in a way that would not seem obvious from its major themes and the risk-averse publishing strategies increasingly adopted by the multinational conglomerates controlling the Australian industry. The research explores the nature of connections between writing, publishing and reading Holocaust literature, seeking to answer the following questions: What are the driving forces that compel children of Holocaust survivors to write about their parents' lives and their own experiences of growing up in a 'survivor' family? By what mechanisms are such stories published in an Australian industry dominated by international conglomerates focused on mass-market publishing? How do readers receive and make sense of this material?

The major component of the thesis is a manuscript of poetry titled How do detectives make love? which includes forty poems written over a period of two years. Many of these; poems have been published in literary journals and magazines both in Australia and internationally as well as being performed at various performance poetry venues. How do detectives make love? was accepted for publication by Penguin Books, Australia in 1994. Also included is a 12,000 word exegesis in support of the manuscript titled How do detectives make love? Themes of the survival of the child: corruption in relation to innocence. The exegesis explores various themes and motifs occurring throughout the work, including the motif of birds and dogs, and the themes of love and the police, guns and weaponry, the outback and parklands, the parents, the change from childhood to adolescence and adolescence to adulthood, and the survival of the child. The current vital social relevance of these themes and motifs is explored in the poems. The literary use of the themes is explored comparatively with the work of other Australian poets including Gig Ryan, Kenneth Slessor and Les Murray. The purpose of the exegesis is to give the reader insights into the poet's intellectual processes and literary concerns throughout the work itself.

Habitat loss, fragmentation and degradation are drivers of major declines in biodiversity and species extinctions. The actual causes of species population declines following habitat change are more difficult to discern and there is typically high covariation among the measures used to infer the causes of decline. The causes of decline may act directly on individual fitness and survival, or through disruption of population processes. We examined the relationships among configuration, extent and status of native vegetation and three commonly used indicators of individual body condition and chronic stress (haemoglobin level, haematocrit, residual body mass condition index) in 13 species of woodland-dependent birds in south-eastern Australia. We also examined two measures of changes to population processes (sex ratio and individual homozygosity) in ten species and alleic richness in five species. We found little support for relationships between site or landscape characteristics and individual or population response variables, notwithstanding that our simulations showed we had sufficient power to detect relatively small effects. We discuss possible causes of the absence of detectable habitat effects in this system and the implications for the usefulness of individual body condition and easily measured haematological indices as indicators of the response of avian populations to habitat change. © 2012 The Authors.

The internet revolution has affected everybody in some way. Technologies used in business range from telephones to industry-specific machinery. Mostly though, business technology has come to mean the internet. In literature concerning innovation and the adoption of technology in business, research invariably centres on small to medium businesses (SI'v1Es), as these can be defined reasonably easily. Statistics on family businesses are limited, however, because family businesses are so difficult to categorize and define.

The Australian Family Business Survey of 1993 (Institute of Chartered Accountants) determined that family business is the largest form of business ownership in Australia and represents 83% of all business enterprises, although Basu (2004) believes that over two thirds of all world-wide businesses are owned or managed by families and around half of all businesses in Australia are family businesses. The Australian Institute of Management (AIM) (2004) states that the wealth of family and private businesses is estimated at $3.6 trillion and that family firms generate 50 per cent of Australia's employment growth, account for 40 per cent of Australia's private sector output, and are a seed bed for innovation and the information of large companies.

The difficulty in defining a family business is heightened because family businesses can take many forms ranging from sole traders to private companies to public companies. Hence, when talking about family business, you could be referring to the sole trader dealing with organic produce to an IT organisation employing hundreds of staff. Basu (2004) thinks that while ordinarily, in non-family businesses, the business and family domains remain separate, the key distinctive characteristic of family businesses is that family members work together for economic purposes. In other words, the family is not merely a social unit but also an economic unit. Craig and Lindsay (2002) believe that family involvement in the business is what makes the family business different... researchers, however, cannot seem to agree as to what constitutes 'family involvement' in a business so that it can be defined as a family business and that family business is ... a business that is governed and/or managed with the intention to shape and pursue the vision of the business held by a dominant coalition that is controlled by members of the same family or a small number of families in a manner that is potentially sustainable across generations of the family or families.

This paper argues that the entrepreneurial leader in non-profit PAOs has received too little attention in literature pertaining to these organisations. This criticism also applies to museums. The paper explores how leaders in non-profit performing arts organisations balance the interests of the various funding sources and market opportunities to service their revenue requirements. It reviews a tension in non-profit performing arts organisations: the relationship between limited funding and the subsequent need to act entrepreneurially and innovatively among the various funding sources. Using longitudinal analysis of annual reports, the paper uncovers interplay essential to entrepreneurship. Hence, strategies and tensions are highlighted that non-profit leaders have used. Comparisons are made with non-profit art museums which previous research has shown have the same funding tensions.

There is widespread concern about population decline in a number of woodland-dependent birds in southern Australia. Of all declining species, approximately half forage on the ground. This study examined the avifaunal assemblages of temperate woodlands of the Northern Plains, Victoria, to investigate the importance of woodland habitats for ground-foraging species. Four main types of woodland were surveyed (white cypress-pine, black box, grey box and river red gum) and, in total, 89 bird species were detected. All four woodland types differed in habitat structure and, in turn, supported significantly different avifaunal assemblages. Forty of the 89 species (45%) foraged, at least in part, on the ground. Species richness and abundance of ground-foragers differed significantly between woodland types, being highest in white cypress-pine and black box. There was a greater richness of ground-foragers during the breeding than non-breeding season, but abundance did not vary seasonally. Overall, ground-foraging birds comprised a greater proportion of species (>55%) and individuals (>60%) in white cypress-pine and black box woodland than in grey box and river red gum (42–48% of species, <50% individuals). Those ground-foragers regarded as declining also occurred in greatest richness in white cypress-pine woodlands, one of the most depleted habitats in the region. The lowest richness of ‘declining’ ground-foraging species was in river red gum woodland, the most widespread woodland type. Throughout Australia, the proportion of ground-foraging species in bird assemblages tends to be greater in temperate, semi-arid or arid woodlands than in moist forests and rainforests. However, in many regions woodland habitats are severely depleted and their open ground layer is particularly vulnerable to degradation. The extent of suitable habitat for ground-foraging birds in temperate woodlands may be much less than is apparent from current measures of tree cover. Sustainable management of drier (non-riverine) temperate woodlands is required to conserve this important element of the Australian avifauna.

To anticipate the effects of climate change on Australia’s avifauna, it is first necessary to understand the current effects of climate (including climate variability) on life histories, and to examine the scope and nature of existing data that may provide the necessary historical context to anticipate the effects of climate change. This study examines naturally occurring geographical gradients (altitude, latitude) and the Southern Oscillation Index (SOI) as integrated measures of climate. These are then compared with the timing and ‘amount’ of breeding recorded for the Australian Magpie (Gymnorhina tibicen) using data from Birds Australia’s Nest Record Scheme and Atlas of Australian Birds, the NSW Bird Atlassers Inc.’s NSW Bird Atlas, and the Canberra Ornitholgists Group’s Garden Bird Survey. For this common, easily identified species, these data suggest links between Australian Magpie breeding and all three environmental variables. Breeding became later as altitude increased, the proportion of breeding records increased from north to south, and years of high SOI corresponded to more (and earlier) breeding in this species. That annual climatic fluctuations have a direct, immediate and substantial effect on breeding in the Australian Magpie, particularly on the amount of breeding that occurs, implies that longer term changes in climate will have substantial impacts on populations. Results were not solely temperature-driven, which makes predicting climate change impacts difficult. For rainfall, predictions are far less precise and regional variation is higher. The results also highlight the potential and limitations of current survey techniques for documenting the impacts of climate change on birds; in particular, the Nest Record Scheme does not measure the amount of breeding that occurs, but a useful index of this can be derived from bird atlassing data
