Charting a theoretical framework for examining Indigenous journalism culture

Indigenous media around the globe have expanded considerably in recent years, a process that has also led to an increase in the number of Indigenous news organisations. Yet, research into Indigenous news and journalism is still rare, with mostly individual case studies having been undertaken in different parts of the globe. Drawing on existing research gathered from a variety of global contexts, this paper theorises five main dimensions which can help us think about and empirically examine Indigenous journalism culture. They include: the empowerment role of Indigenous journalism; the ability to offer a counter-narrative to mainstream media reporting; journalism’s role in language revitalisation; reporting through a culturally appropriate framework; and the watchdog function of Indigenous journalism. These dimensions are discussed in some detail, in an attempt to guide future studies into the structures, roles, practices and products of Indigenous journalism across the globe.

'The Australian we all aspire to be' : commemorative journalism and the death of the Crocodile Hunter

This article examines the news coverage the death of Steve Irwin, widely known as the Crocodile Hunter, generated in Australia. In line with past research on commemorative journalism, the study demonstrates the dominant discourses employed in the reporting of Irwin's death. It is argued that Australia's newspapers invoked a number of national myths, such as mateship, larrikinism and anti-elitism, in order to re-assert notions of Australian identity and social values and to deal with the grief over his loss. Most importantly, the study sheds new light on how news media deal with challenges to the dominant memorialising discourse. Past studies had not been able to investigate in much detail alternative discourses, but in examining Irwin's death, we are able to see how the media deal with such an unwanted interruption. It is argued that newspapers appropriated the alternative perspective within the mythical terms of their memorialising discourse, thereby not allowing it to disrupt the memorialisation itself and in fact further strengthening the process of mythologising the Crocodile Hunter.

Rural people and the land

There is a long and fundamental connection between rural place and the land. Whereas land is simply the foundation for the construction of towns and cities, whose urban culture and economy thrives on human ingenuity and industry that may have little direct attachment to the physical ground over which it occurs, historical discourses of rurality place the land at the heart of the rural economy and society. Rural people, such discourses hold, live on the land, work the land, tend the land and know the land. The land formed not only the base of the rural economy (as ‘a physical, tangible resource which can be ploughed, sown, grazed, built upon’ (Macnaghten and Urry 1998, 200)), but also shaped rural culture and the rural calendar, and contributed to the constitution of the rural character (see Bell 1994). As such, the land is central to rural sense of place.

Seeds of cosmopolitan future? Young people and their aspirations for future mobility

Mobility across space is an exemplary characteristic of the global era and an important aspect of the cultural experience of many people in advanced industrialised nations. Mobility evokes powerful images that effectively counter any illusion of stationary life and provide a break from the insularity of the local and parochial. High levels of mobility are simultaneously a fact, a necessity and a cultural aspiration. In recent times, debates about mobility in social theory have considered the relationship between mobility and cosmopolitan culture and identities (Hannerz, 1990, Urry, 1990, 2000, Beck, 2006). Against this backdrop, this paper also draws on some of the more recent discussions about the emergence of globalised and cosmopolitan identities among young people (Beck and Beck-Gernsheim, 2009). Using data from a longitudinal study of young people in Queensland, this paper provides an insight into young people’s aspirations about future mobility. The data affirm Skeggs’ (2004) comment that mobility is an unequal resource, and demonstrate that aspirations of future mobility reflect numerous social, economic and cultural realities of young people’s lives. This inevitably leads us to problematise the established, and often abstract, nexus between cosmopolitanism and mobility in contemporary debates about cosmopolitanism.

Journalism, gender, feminist theory and news reporting on the Australian Football League

This article reports on a review of selected theory and practice in sports journalism to determine if the prominence of female journalists reporting the news of a major sporting movement, and industry, the Australian Football League (AFL) could be attributed to a feminist response to the traditional domination of male values in the sports media complex. The article reviews selected literature to establish that, on the evidence presented, male values have traditionally dominated the news. It then considers feminist theory and alternative feminist responses to the domination of male values in the newsroom. Consideration is also given to Australian research on the ‘seriousness’ of sports news and its coverage (or lack thereof) of more ‘feminine’ news values including human interest stories, stories about culture and those on serious social issues. Interviews with a select group of female journalists who write about the AFL for The Age newspaper in Melbourne are recounted, with a focus on the journalists’ work experiences. The article concludes by drawing together the research findings to demonstrate that, although feminine news values are represented in only a small proportion of AFL news stories, there is evidence to suggest they are afforded a high degree of presentational prominence which reflects the needs and expectations of a female audience. It shows that female journalists do play a meaningful role in the AFL media and that, given the evidence presented, a feminist response to the traditional domination of male values in the sports media complex could indeed be applicable, and taking place.

Successful outcomes in vocational education and training courses and mathematics: how pedagogy and expectations influence achievement

This paper reports on a four year Australian Research Council funded Linkage Project titled Skilling Indigenous Queensland, conducted in regional areas of Queensland, Australia from 2009 to 2013. The project sought to investigate Vocational Education and Training (VET) and teaching, Indigenous learners’ needs, employer culture and expectations and community culture and expectations to identify best practice in numeracy teaching for Indigenous VET learners. Specifically it focused on ways to enhance the teaching and learning of courses and the associated mathematics in such courses to benefit learners and increase their future opportunities of employment. To date thirty - nine teachers/trainers/teacher aides and two hundred and thirty - one students consented to participate in the project. Nine VET courses offered in schools and Technical and Further Education Institutes (TAFE) were nominated to be the focus on the study. This paper focuses on student questionnaire responses and interview responses from teachers/trainers one high school principal and five students as a result of these processes, the findings indicated that VET course teachers work hard to adopt contextualising strategies to their teaching; however this process is not always straight forward because of the perceptions of how mathematics has been taught and learned by trainers and teachers. Further teachers, trainers and students have high expectations of one another with the view to successful outcomes from the courses.

Unintended consequences : satellite policy and Indigenous television

This article examines two instances of media policy involving satellite transmission and Indigenous television: the introduction of the Viewer Access Satellite Television (VAST) platform in 2010 and the introduction of AUSSAT in the mid-1980s. The government’s failure to provide community and Indigenous broadcasters with an access regime at the time of AUSSAT resulted in Australia’s first and only Indigenous commercial television licensee, Imparja. Over a quarter of a century later, Imparja now forms part of the joint-venture company that runs VAST, a key component of Australia’s digital switchover planning. During the passage of the legislative amendments required to establish VAST, the issue of access resurfaced – this time in relation to Australia’s national and community Indigenous television channels. The article recounts the events leading up to the 2010 Bill, and examines the intended and unintended consequences of satellite policy in relation to Indigenous media, including equalisation and transparency of government funding programs.

‘Redstone is like electricity’: Children's performative representations in and around Minecraft

In this article, we investigate eight and nine year old girls’ school and home use of the popular game Minecraft and the ways in which the girls ‘bring themselves into being’ through talk and digital production in the social spaces of the classroom and within the game’s multiplayer online world. This work was conducted as part of a broader digital games in education project involving primary and secondary school-aged students in Australia and focuses specifically on data collected from an all-girls primary school in Brisbane. We investigate the processes of identity construction that occur as the girls undertake practices of curatorship (Potter, 2012) to display their knowledge of Minecraft through discussion of the game, both ‘in world’ and in face-to-face interactions, and as they assemble resources within and around the game to design, build and display their creations and share stories about their game play. The article begins with a consideration of recent scholarship focussing on children, learning and digital culture and literacy practices before explaining how Minecraft is, in many ways, an exemplary instance of a digital game that promotes and enables complex practices of digital participation. We then introduce the concepts of performativity and recognition (Butler 1990, 2004, 2005) which, we argue, provide productive ways to theorise identity work within affinity groups. The article then outlines some background to the research project and our methodology before providing analysis of the data in the second half of the article. We conclude by outlining the implications of our investigation for the conceptualisation of learning spaces as affinity groups and for considering digital participation as curatorship.

The moderating role of entrepreneurial management in the relationship between absorptive capacity and corporate entrepreneurship : an attention-based view

Building on the attention-based view, we argue that companies need a challenging mechanism to focus their absorptive capacity attention on corporate entrepreneurship versus mainstream activities or other purposes. We suggest entrepreneurial management as the attential driver for deploying absorptive capacity towards corporate entrepreneurship. From our analysis of a sample of 331 supplier companies providing products and services to the mining industry of Australia and Iran, we observe that absorptive capacity positively affects corporate entrepreneurship. The data also demonstrate that the effect of absorptive on corporate entrepreneurship increases when firms adopt the entrepreneurial culture and reward systems. However, the entrepreneurial growth and resource orientations negatively moderate the relationship between absorptive capacity and corporate entrepreneurship.

Supernatants of acquired immunodeficiency syndrome-related Kaposi's sarcoma cells induce endothelial cell chemotaxis and invasiveness

Kaposi's sarcoma (KS) in general, and acquired immunodeficiency syndrome-related KS (AIDS-KS) in particular, is a highly invasive and intensely angiogenic neoplasm of unknown cellular origin. We have recently established AIDS-KS cells in long term culture and reported the development of KS-like lesions in nude mice inoculated with these cells. Here, we have examined the in vitro invasiveness of basement membrane by AIDS-KS cells, as well as the effect(s) of their supernatants on the migration and invasiveness of human vascular endothelial cells. AIDS-KS cells were highly invasive in the Boyden chamber invasion assay and formed invasive, branching colonies in a 3-dimensional gel (Matrigel). Normal endothelial cells form tube-like structures on Matrigel. AIDS-KS cell-conditioned media induced endothelial cells to form invasive clusters in addition to tubes. KS-cell-conditioned media, when placed in the lower compartment of the Boyden chamber, stimulated the migration of human and bovine vascular endothelial cells across filters coated with either small amounts of collagen IV (chemotaxis) or a Matrigel barrier (invasion). Basic fibroblast growth factor could also induce endothelial cell chemotaxis and invasion in these assays. However, when antibodies to basic fibroblast growth factor were used the invasive activity induced by the AIDS-KS-cell-conditioned media was only marginally inhibited, suggesting that the large quantities of basic fibroblast growth factor-like material released by the AIDS-KS cells are not the main mediators of this effect. Specific inhibitors of laminin and collagenase IV action, which represent critical determinants of basement membrane invasion, blocked the invasiveness of the AIDS-KS cell-activated endothelial cells in these assays. These data indicate that KS cells appear to be of smooth muscle origin but secrete a potent inducer of endothelial cell chemotaxis and invasiveness which could be responsible for angiogenesis and the resulting highly vascularized lesions. These assays appear to be a model to study the invasive spread and angiogenic capacity of human AIDS-related KS and should prove useful in the identification of molecular mediators and potential inhibitors of neoplastic neovascularization.

The LCC15-MB human breast cancer cell line expresses osteopontin and exhibits an invasive and metastatic phenotype

We have characterized the LCC15-MB cell line which was recently derived from a breast carcinoma metastasis resected from the femur of a 29-year-old woman. LCC15-MB cells are vimentin (VIM) positive, exhibit a stellate morphology in routine cell culture, and form penetrating colonies when embedded in three-dimensional gels of Matrigel or fibrillar collagen. They show high levels of activity in the Boyden chamber chemomigration and chemoinvasion assays, and like other invasive human breast cancer (HBC) cell lines, LCC15-MB cells activate matrix-metalloproteinase-2 in response to treatment with concanavalin A. In addition, these cells are tumorigenic when implanted subcutaneously in nude mice and recolonize bone after arterial injection. Interestingly, both the primary lesion and the bone metastasis from which LCC15-MB were derived, as well as the resultant cell line, abundantly express the bone matrix protein osteopontin (OPN). OPN is also expressed by the highly metastatic MDA-MB-435 cells, but not other invasive or noninvasive HBC cell lines. Expression of OPN is retained in the subcutaneous xenograft and intraosseous metastases of LCC15-MB as detected by immunohistochemistry. Both VIM and OPN expression have been associated with breast cancer invasion and metastasis, and their expression by the LCC15-MB cell line is consistent with its derivation from a highly aggressive breast cancer. These cells provide a useful model for studying molecular mechanisms important for breast cancer metastasis to bone and, in particular, the implication(s) of OPN and VIM expression in this process.

Myoepithelial molecular markers in human breast carcinoma PMC42-LA cells are induced by extracellular matrix and stromal cells

The microenvironment plays a key role in the cellular differentiation of the two main cell lineages of the human breast, luminal epithelial, and myoepithelial. It is not clear, however, how the components of the microenvironment control the development of these cell lineages. To investigate how lineage development is regulated by 3-D culture and microenvironment components, we used the PMC42-LA human breast carcinoma cell line, which possesses stem cell characteristics. When cultured on a two-dimensional glass substrate, PMC42-LA cells formed a monolayer and expressed predominantly luminal epithelial markers, including cytokeratins 8, 18, and 19; E-cadherin; and sialomucin. The key myoepithelial-specific proteins α-smooth muscle actin and cytokeratin 14 were not expressed. When cultured within Engelbreth-Holm- Swarm sarcoma-derived basement membrane matrix (EHS matrix), PMC42-LA cells formed organoids in which the expression of luminal markers was reduced and the expression of other myoepithelial-specific markers (cytokeratin 17 and P-cadherin) was promoted. The presence of primary human mammary gland fibroblasts within the EHS matrix induced expression of the key myoepithelial-specific markers, α-smooth muscle actin and cytokeratin 14. Immortalized human skin fibroblasts were less effective in inducing expression of these key myoepithelial-specific markers. Confocal dual-labeling showed that individual cells expressed luminal or myoepithelial proteins, but not both. Conditioned medium from the mammary fibroblasts was equally effective in inducing myoepithelial marker expression. The results indicate that the myoepithelial lineage is promoted by the extracellular matrix, in conjunction with products secreted by breast-specific fibroblasts. Our results demonstrate a key role for the breast microenvironment in the regulation of breast lineage development.

Heregulin regulates the actin cytoskeleton and promotes invasive properties in breast cancer cell lines

The metastatic process requires changes in tumor cell adhesion properties, cell motility and remodeling of the extracellular matrix. The erbB2 proto-oncogene is overexpressed in approximately 30% of breast cancers and is a major prognostic parameter when present in invasive disease. A ligand for the erbB2 receptor has not yet been identified but it can be activated by heterodimerization with heregulin (HRG)-stimulated erbB3 and erbB4 receptors. The HRGs are a family of polypeptide growth factors that have been shown to play a role in embryogenesis, tumor formation, growth and differentiation of breast cancer cells. The erbB3 and erbB4 receptors are involved in transregulation of erbB2 signaling. The work presented here suggests biological roles for HRG including regulation of the actin cytoskeleton and induction of motility and invasion in breast cancer cells. HRG-expressing breast cancer cell lines are characterized by low erbB receptor levels and a high invasive and metastatic index, while those which overexpress erbB2 demonstrate minimal invasive potential in vitro and are non-tumorigenic in vivo. Treatment of the highly tumorigenic and metastatic HRG-expressing breast cancer cell line MDA-MB-231 with an HRG-neutralizing antibody significantly inhibited proliferation in culture and motility in the Boyden chamber assay. Addition of exogenous HRG to non-invasive erbB2 overexpressing cells (SKBr-3) at low concentrations induced formation of pseudopodia, enhanced phagocytic activity and increased chemomigration and invasion in the Boyden chamber assay. The specificity of the chemomigration response to HRG is demonstrated by inhibition with the anti-HRG neutralizing antibody. These results suggest that either HRG can act as an autocrine or paracrine ligand to promote the invasive behavior of breast cancer cells in vitro or thus may enhance the metastatic process in vivo.

Curse or cure? Revisiting state, capital and resources

WA’s experience, as portrayed in this volume, not only highlights the changeable nature of the mining industry, the volatility of global commodity markets and the impact of global capital on people and place, it also draws into question the promise of lasting value derived from resource development as currently practiced. It is in this context that Chapter 18 revisits WA's resource boom and assesses the sustainability of resource-led development in the state, to arrive at an answer to the question of ‘curse or cure?’. Opening up the discourse beyond the dominant developmentalist narrative invites discussion on new perspectives of economic sustainability that include well-being, equity and the protection of people, culture and place.
