Myths and absent signifiers in representations of Aboriginal identity in Australian cinema

This article examines how meaning is always articulated in the ideological and political structures of society. This becomes apparent when evidencing articulated Aboriginal representation in Australian cinema, which signifies a representation on screen expressive of the ideological and political structures of the historical time periods in which the films were produced. Meaning, which is the relationship between the signifier and its signified, includes both denotation and connotation. Specific connotators can load a sign with multiple meanings leading to a chain of connotations.  The connotations of Aboriginal identity in Australian filmic narratives are influenced by a chain of additional signified, those of: socio-cultural variables and dominant discourses. This article analyses these chains of connotations through an examination of myths and absent signifiers in filmic representations of Aboriginal identity. The films investigated are: Jedda (Charles Chauvel 1955), Walkabout (Nicolas Roeg 1971), Night Cries (Tracey Moffatt 1990) and Rabbit Proof Fence (Philip Noyce 2002).

Alzheimer's disease, media representations and the politics of euthanasia: constructing risk and selling death in an ageing society

Drawing on extensive data including news media reports and commentaries, documentaries, courts and court reports, films, websites, professional literature and government and non-government agencies, this book explores the 'Alzheimerisation' of the euthanasia debate, examining the shift in recent years in public attitudes towards the desirability and moral permissibility of euthanasia as an end-of-life 'solution' for people living with the disease - not just at its end stage, but also at earlier stages. With attention to mediarepresentations and public understandings of Alzheimer's disease, Alzheimer's Disease, Media Representations and the Politics of Euthanasia sheds light on the processes contributing to these changes in public opinion, investigating the drivers of vexed political debate surrounding the issue and examining the manner in which both sides of the euthanasia debate mobilise support, portray their opponents and make use of media technologies to frame the terms of discourse. Paving the way for a greater level of intellectual honesty with regard to an issue carrying significant policy implications, this book will be of interest to scholars of media and communication, social movements and political communication, and the sociology of health and medicine, as well as researchers and professionals in the fields of palliative and end of life care.

Any one of these boat people could be a terrorist for all we know! Media representations and public perceptions of ‘boat people’ arrivals in Australia

In April 2009 a boat (named the ‘SIEV 36’ by the Australian Navy) carrying 49 asylum seekers exploded off the north coast of Australia. Media and public debate about Australia’s responsibility to individuals seeking asylum by boat was instantaneous. This paper investigates the media representation of the ‘SIEV 36’ incident and the public responses to media reports through online news fora. 

Global positioning systems : altered representations of place

Global Positioning Systems: altered representations of place, presents an exegesis from the practice led research submitted for the degree of Master of Fine Art at the Victorian College of the Arts. The thesis proposes a particular understanding of altered states of consciousness that is relevant to my practice.  This is outlined by Charles Tart and supported by the Altered States of Consciousness Consortium and explores a psycho-aesthetic experiences and does not involved transcendental states or spiritual associations. These experiences are transformed by an exhaustive application of digital technologies, where mosaic-like complexity emerges that induces sustained disorientation and surrounds a viewer in an immersive space.

Constructing representations to learn in science

Current research into student learning in science has shifted attention from the traditional cognitivist perspectives of conceptual change to socio-cultural and semiotic perspectives that characterize learning in terms of induction into disciplinary literacy practices. This book builds on recent interest in the role of representations in learning to argue for a pedagogical practice based on students actively generating and exploring representations. The book describes a sustained inquiry in which the authors worked with primary and secondary teachers of science, on key topics identified as problematic in the research literature. Data from classroom video, teacher interviews and student artifacts were used to develop and validate a set of pedagogical principles and explore student learning and teacher change issues. The authors argue the theoretical and practical case for a representational focus. The pedagogical approach is illustrated and explored in terms of the role of representation to support quality student learning in science. Separate chapters address the implications of this perspective and practice for structuring sequences around different concepts, reasoning and inquiry in science, models and model based reasoning, the nature of concepts and learning, teacher change, and assessment. The authors argue that this representational focus leads to significantly enhanced student learning, and has the effect of offering new and productive perspectives and approaches for a number of contemporary strands of thinking in science education including conceptual change, inquiry, scientific literacy, and a focus on the epistemic nature of science.

Sparse Representations of Image via Overcomplete Dictionary Learned by Adaptive Non-orthogonal Sparsifying Transform

How to learn an over complete dictionary for sparse representations of image is an important topic in machine learning, sparse coding, blind source separation, etc. The so-called K-singular value decomposition (K-SVD) method [3] is powerful for this purpose, however, it is too time-consuming to apply. Recently, an adaptive orthogonal sparsifying transform (AOST) method has been developed to learn the dictionary that is faster. However, the corresponding coefficient matrix may not be as sparse as that of K-SVD. For solving this problem, in this paper, a non-orthogonal iterative match method is proposed to learn the dictionary. By using the approach of sequentially extracting columns of the stacked image blocks, the non-orthogonal atoms of the dictionary are learned adaptively, and the resultant coefficient matrix is sparser. Experiment results show that the proposed method can yield effective dictionaries and the resulting image representation is sparser than AOST.

"It's about freedom": contesting dominant representations of devout Muslim women in the space of the nation

Since September 11 there has been a rise of Islamophobia in Australian public discourse, matched by a growth of racialised attacks on visibly identifiable Muslims in public space. These cultural racisms have arisen in a context where Islamic religious signifiers and practices have come to be read as signs of fundamentalism, terrorism and threat to national political traditions and cultural values. In particular, the hijab has become a symbol of these tensions, with the veiled woman being read as the embodiment of a ‘repressive and fundamentalist religion’. However, as some Muslim and feminist scholars have proposed, these readings rob Muslim women of their ability to articulate the reasons why wear the veil or engage in gendered religious practices. This paper argues that this enacts a form of disembodiment, whereby Muslim womens’ ability to comfortably inhabit their bodies and assert themselves in the public sphere is limited. In particular the paper draws upon two case studies which express this disembodiment, whilst highlighting the counter-strategies that devout Muslim women are adopting to reinsert their bodies and narratives in the national frame. The first refers to the recent media backlash which followed a public lecture held at Melbourne University by Islamic organization Hikmah Way, where the audience was segregated along gender lines. The second draws upon interviews conducted with veiled Muslim women in Sydney, following the Cronulla riot. These interviews show how Muslim women are contesting dominant representations of the hijab in western popular discourse by recoding it as a signifier of religious and national identity, and as an expression of democratic freedom.

China in a book: Victorian representations of the 'celestial kingdom' in William Dalton’s 'The wolf boy of China'

Despite the wealth of material related to China in Victorian and Edwardian children’s literature, relatively few scholarly works have been published on the subject. Critics who have discussed the topic have tended to emphasize the negative discourse and stereotypical images of the Chinese in late nineteenth-century children’s literature. I use the case of William Dalton’s The Wolf Boy of China (1857), one of the earliest full-length Victorian children’s novels set in China, to complicate previous generalizations about negative representations of China and the Chinese and to highlight the unpredictable nature of child readers’ reactions to a text. First, in order to trace the complicated process of how information about the country was disseminated, edited, framed, and translated before reaching Victorian and Edwardian readers, I analyse how Dalton wove fragments from his reading of a large archive of texts on China into his novel.
Although Dalton may have preserved and transmitted some ‘factual’ information about China from his sources, he also transformed material that he read in innovative ways. These are reflected in the more subversive and radical parts of the novel, which are discussed in the second part of the essay. In the final section, I provide examples of historical readers of The Wolf Boy of China to challenge the notion that children passively accept the imperialist messages in books of empire.
