Visions of the virtual : the role of computers and artificial intelligence in a selection of Australian young adult fiction

Advances in computer technology over the last twenty years have resulted in a number of different visions of what it means to be real, and of what it means to be human. This paper will explore how computers and artificial intelligence are used as major themes in four Australian novels written for young adults: Gillian Rubinstein’s Space Demons trilogy — comprising Space Demons, Skymaze and Shinkei — and Michael Pryor’s The Mask of Caliban. In so doing, the paper will look at how these texts explore the relationship between increasingly developed technology and visions of a better world. By comparing a series of oppositions that occur in all four books, this paper will look at how the theme of technology is used to privilege particular values and to advocate particular beliefs.

Women's silence : in the space of words and images

My thesis is made up of words and images. This study investigates the way in which silence operates productively within and between the two modes of communication. I suggest that in the process of changing words into images or scripto-visual art-practice, the silence in women's lives can be articulated. I argue that women draw on the generative qualities of silence to create forms of speech that override the cultural constructions of gender which have placed them within the space of ‘mute’ silence. To gain an historical perspective of this practice by women, I consider the lives of medieval nuns within religious enclosure and their work with words and images in the illuminated manuscript. I make a comparative study of original illuminated manuscripts, focussing mainly on visual language and locating aspects of the work closest to my own art-practice: the visual treatment of the space and inter-textual components of the page or folio. This project does not include an examination of miniatures or historiated initials. Rather, its aim is to identify and compare the use of other aesthetic devices available to the medieval scribe/artist through which they might have interacted with the text. I suggest links between verbal and visual performances of language and the repetition, or copying of texts by medieval nuns, as a means of female embodiment of words and their spaces. From the outcomes of my studio investigations and my consideration of other contemporary feminist art practices, I demonstrate how women artists may ‘re-write’ the text and ‘speak’ their silence through visual language and the acts of writing, drawing and painting the words of others. Through my engagement with feminist critical theory, the work of medieval scholars, original illuminated manuscripts and my studio research, I propose that scripto-visual practice remains particularly significant for women despite the differences between the medieval period and our own. As a generative practice, it negotiates some of the societal constraints on women's speech and visibility, because its language is ‘silent and disembodied’ from the image of woman constructed by male discourse. It is a form of speech that acknowledges as it defies the social and cultural conditions that shaped its necessity, articulating an alternative voice of women in the space of words and images.

In situ photopolymerization of a gel ionic liquid electrolyte in the presence of iodine and its use in dye sensitized solar cells

We report for the first time an in situ photopolymerization of model co-monomers, 2-hydroxyethyl methacrylate (HEMA) and tetra (ethylene glycol) diacrylate (TEGDA), in an IL electrolyte containing I₂ for DSSCs. TiO₂ nanoparticles were used as the photo-initiator and co-gelator in a charge transfer polymerization reaction. The gel-IL polymer obtained was characterized in terms of the diffusion properties of the electrolyte. Preliminary results from DSSCs assembled using the gel-IL electrolyte showed energy conversion efficiency of 3.9% at 1 sun (AM1.5) and 5.0% at 0.39 sun illumination.

Emotional connections to books and technological innovations : an e-book perspective

E-book devices are a technological innovation that has been mass marketed to consumers as a revolution in the way that books will be read and stored. This paper extends previous research on technology adoption behaviour of individuals by focusing on the role of emotional connections people have towards e-books. A number of technology adoption models can explain the adoption of e-book devices such as the technology acceptance model, theory of planned action, theory of reasoned action and social cognitive theory. Due to the increased importance of social learning on a person’s behaviour, social cognitive theory is identified in this paper as being the most appropriate theoretical lens to understand the emotional connections a person has towards e-books. The findings from this paper may help to fill the gaps in academic discussion about what theory best explains a person’s behavioural intention towards technological innovations and the impact of marketing on this behaviour. In addition, the paper has a number of managerial implications including identifying the importance of an emotional connection to a technological innovation that influences the adoption process. The emphasis on emotional connection as mediating the way a person receives information about e-book devices may help to influence future marketing efforts of new technologies.

A tale of two parasites : the comparative epidemiology of cryptosporidiosis and giardiasis

New Zealand has a higher reported incidence of cryptosporidiosis and giardiasis than most other developed countries. This study aimed to describe and compare the epidemiology of these infections in New Zealand, to better understand their impact on public health and to gain insight into their probable modes of transmission. We analysed cryptosporidiosis and giardiasis notification data for a 10-year period (1997–2006). Highest rates for both diseases were in Europeans, children aged 0–5 years, and those living in low-deprivation areas. Cryptosporidiosis distribution was consistent with mainly farm animal (zoonotic) reservoirs. There was a dose–response relationship with increasing grades of rurality, marked spring seasonality, and positive correlation with farm animal density. Giardiasis distribution was consistent with predominantly human (anthroponotic) reservoirs, with an important contribution from overseas travel. Further research should focus on methods to reduce transmission of Cryptosporidium in rural areas and on reducing anthroponotic transmission of Giardia.

Historiographic foodways: a survey of food and drink histories in Australia

This essay is a survey of the field of food and drink history in Australia since the 1970s. It discusses the range of research and picks out key historiographic aspects: the search for an Australian cuisine; regional food cultures; connection between sources and historical interpretation; and the interdisciplinarity of food and drink history. It suggests that as food and drink histories have broadened beyond a search for culinary traditions and a gastronomic sensibility, so our understanding of food and drink in Australian history has deepened. It also argues that food and drink history is more than textual knowledge in books and articles: television programs and exhibitions held in museums and libraries, for example, have enhanced our understanding of food and drink histories.

Infrared face recognition: a comprehensive review of methodologies and databases

Automatic face recognition is an area with immense practical potential which includes a wide range of commercial and law enforcement applications. Hence it is unsurprising that it continues to be one of the most active research areas of computer vision. Even after over three decades of intense research, the state-of-the-art in face recognition continues to improve, benefitting from advances in a range of different research fields such as image processing, pattern recognition, computer graphics, and physiology. Systems based on visible spectrum images, the most researched face recognition modality, have reached a significant level of maturity with some practical success. However, they continue to face challenges in the presence of illumination, pose and expression changes, as well as facial disguises, all of which can significantly decrease recognition accuracy. Amongst various approaches which have been proposed in an attempt to overcome these limitations, the use of infrared (IR) imaging has emerged as a particularly promising research direction. This paper presents a comprehensive and timely review of the literature on this subject. Our key contributions are (i) a summary of the inherent properties of infrared imaging which makes this modality promising in the context of face recognition; (ii) a systematic review of the most influential approaches, with a focus on emerging common trends as well as key differences between alternative methodologies; (iii) a description of the main databases of infrared facial images available to the researcher; and lastly (iv) a discussion of the most promising avenues for future research. © 2014 Elsevier Ltd.

Accommodating taboo language in English language teaching: issues of appropriacy and authenticity

Culturally specific language practices related to vernacular uses of taboo language such as swearing represent a socially communicative minefield for learners of English. The role of classroom learning experiences to prepare learners for negotiation of taboo language use in social interactions is correspondingly complicated and ignored in much of the language teaching research literature. English language teachers confront not only obstacles to effective development of sociolinguistic and cultural knowledge in classroom instruction, and failure of course-books to address taboo language, but also uncertainties they themselves have about addressing such obstacles and omissions. In this paper, we draw on interview data from three experienced teachers of English as an additional language, to explore their perceptions and classroom practices in relation to taboo language. In particular, we explore the situational appropriateness of mild taboo swearing using the lexical item, bloody, which has a strong positioning in Australian language culture. Dilemmas surrounding this potentially troublesome item of Australian English are foregrounded in relation to the extent to which often neglected, but widely used taboo language is actually ‘taboo’ in the classroom.
