Dreams in the Shadows : Vietnamese-Australian Lives in Transition

Explores the experiences of Vietnamese immigrants in Australia. Description What is it like to be a refugee in a country that has a completely different culture from your own, where you feel very different from those around you? With a fine eye for detail and keen empathy for her interviewees, Mandy Thomas explores the experiences of Vietnamese living in Australia. She examines displacement and loss, the ongoing effects of war trauma, and international and community politics. While reflecting on many of the contemporary debates on identity and communality, she explores the concrete realities of Vietnamese lives through their daily experiences. She discusses how Vietnamese families have adapted Western domestic architecture to create a more comfortable home environment, how traditional festivals now serve new purposes, and the changing nature of status and gender relations. She describes the reception of the Vietnamese by the wider Australian society and in the media, and she explores the ongoing ties that overseas Vietnamese have with their homeland. Dreams in the Shadows is a valuable resource for anyone working with immigrant communities, for readers interested in Vietnamese immigration to Western countries, and for researchers of migration and multiculturalism. 'Dreams in the Shadows is a wonderfully sensitive account of Vietnamese in Australia that provides insight into the worlds of Vietnamese immigrants and the often marginalizing orders of the host society.' Bruce Kapferer, Professor of Anthropology, James Cook University and University College London 'A perceptive, sensitive and culturally nuanced account of one of the most recently formed diasporas - that of Vietnamese in Sydney. Deserves to be widely read.' Pnina Werbner, Reader in Social Anthropology, Keele University

Experimental and computer simulation validation of ultrasound phase interference created by lateral inhomogeneity of transit time in replica bone marrow composite models

Purpose: The measurement of broadband ultrasonic attenuation (BUA) in cancellous bone for the assessment of osteoporosis follows a parabolic-type dependence with bone volume fraction; having minima values corresponding to both entire bone and entire marrow. Langton has recently proposed that the primary BUA mechanism may be significant phase interference due to variations in propagation transit time through the test sample as detected over the phase-sensitive surface of the receive ultrasound transducer. This fundamentally simple concept assumes that the propagation of ultrasound through a complex solid : liquid composite sample such as cancellous bone may be considered by an array of parallel ‘sonic rays’. The transit time of each ray is defined by the proportion of bone and marrow propagated, being a minimum (tmin) solely through bone and a maximum (tmax) solely through marrow. A Transit Time Spectrum (TTS), ranging from tmin to tmax, may be defined describing the proportion of sonic rays having a particular transit time, effectively describing lateral inhomogeneity of transit time over the surface of the receive ultrasound transducer. Phase interference may result from interaction of ‘sonic rays’ of differing transit times. The aim of this study was to test the hypothesis that there is a dependence of phase interference upon the lateral inhomogenity of transit time by comparing experimental measurements and computer simulation predictions of ultrasound propagation through a range of relatively simplistic solid:liquid models exhibiting a range of lateral inhomogeneities. Methods: A range of test models was manufactured using acrylic and water as surrogates for bone and marrow respectively. The models varied in thickness in one dimension normal to the direction of propagation, hence exhibiting a range of transit time lateral inhomogeneities, ranging from minimal (single transit time) to maximal (wedge; ultimately the limiting case where each sonic ray has a unique transit time). For the experimental component of the study, two unfocused 1 MHz ¾” broadband diameter transducers were utilized in transmission mode; ultrasound signals were recorded for each of the models. The computer simulation was performed with Matlab, where the transit time and relative amplitude of each sonic ray was calculated. The transit time for each sonic ray was defined as the sum of transit times through acrylic and water components. The relative amplitude considered the reception area for each sonic ray along with absorption in the acrylic. To replicate phase-sensitive detection, all sonic rays were summed and the output signal plotted in comparison with the experimentally derived output signal. Results: From qualtitative and quantitative comparison of the experimental and computer simulation results, there is an extremely high degree of agreement of 94.2% to 99.0% between the two approaches, supporting the concept that propagation of an ultrasound wave, for the models considered, may be approximated by a parallel sonic ray model where the transit time of each ray is defined by the proportion of ‘bone’ and ‘marrow’. Conclusions: This combined experimental and computer simulation study has successfully demonstrated that lateral inhomogeneity of transit time has significant potential for phase interference to occur if a phase-sensitive ultrasound receive transducer is implemented as in most commercial ultrasound bone analysis devices.

Why are children the most important audience for pornography in Australia?

Who watches pornography in Australia? If you listen to public debates about the genre the answer is clear – it’s children. Children are accessing pornography on smartphones (Murray and Tin 2011). Children are taking ‘lewd’ photographs of themselves, creating their own pornography (Nelligan and Etheridge 2011). Indigenous Australian children must be protected by banning pornography (the Age 2011). Pornographic magazines are placed where children can see them (O'Rourke 2011). Exposure to pornography is damaging children (Sundstrom 2011). The Australian Government insists that the Internet must be filtered to protect children from pornography (Collerton 2010). And if indeed any adults are watching pornography in Australia, then it’s child pornography (MacDonald 2011; Ralston and Howden 2011).In story after story, public debate about pornography focuses on children as its audience. There is no suggestion that children are numerically the largest audience of pornography in Australia. But emphatically the suggestion is that children are the most important audience to be taken into account when thinking about the genre. This chapter explores why this is the case, and notes the political advantages and disadvantages of focusing on children as the most important audience for pornography in Australia.

Privacy of RFID - models and protocols

Radio Frequency Identification is a wireless identification method that utilizes the reception of electromagnetic radio waves. This research has proposed a novel model to allow for an in-depth security analysis of current protocols and developed new flexible protocols that can be adapted to offer either stronger security or better efficiency.

The practice of adaptation : turning fact and fiction into theatre

Adaptation of novels and other source texts into theatre has proven to be a recurring and popular form of writing through the ages. This study argues that as the theoretical discourse has moved on from outmoded notions of fidelity to original sources, the practice of adaptation is a method of re-invigorating theatre forms and inventing new ones. This practice-led research employed a tripartite methodology comprised of the writing of two play adaptations, participation by the author/researcher in their productions, and exegetical components focused on the development and deployment of analytical tools. These tools were derived from theoretical literature and a creative practice based on acquired professional artistry "learnt by doing" over a longstanding professional career as actor, director and writer. A suite of analytical tools was developed through the three phases of the first project, the adaptation of Nick Earls’ novel Perfect Skin. The tools draw on Cardwell’s "comparative analysis", which encompasses close consideration of generic context, authorial context and medium-specific context; and on Stam’s "mechanics of narrative": order, duration, frequency, the narrator and point of view. A third analytical lens was developed from an awareness of the significance of the commissioning brief and ethical considerations and obligations to the source text and its author and audience. The tripartite methodology provided an adaptation template that was applied to the writing and production of the second play Red Cap, which used factual and anecdotal sources. The second play’s exegesis (Chapter 10) analyses the effectiveness of the suite of analytical tools and the reception of the production in order to conclude the study with a workable model for use in the practice of adapting existing texts, both factual and fictional, for the theatre.

The Cyndi Lauper affect : bodies, girlhood and popular culture

Using a collective biography method informed by a Deleuzian theoretical approach (Davies and Gannon 2009, 2012), this article analyses embodied memories of girlhood becomings through affective engagements with resonating images in media and popular culture. In this approach to analysis we move beyond the impasse in some feminist cultural studies where studies of popular culture have been understood through theories of representation and reception that retain a sense of discrete subjectivity and linear effects. In these approaches, analysis focuses respectively on decoding and deciphering images in terms of their normative and ideological baggage, and, particularly with moving images, on psychological readings. Understanding bodies and popular culture through Deleuzian notions of “becoming” and “assemblage” opens possibilities for feminist researchers to consider the ways in which bodies are not separate from images but are, rather, becomings that are known, felt, materialized and mobilized with/through images(Coleman 2008a, 2008b, 2008c, 2009, 2011; Ringrose and Coleman 2013). We tease out the implications of this new approach to media affects through three memories of girls’ engagements with media images, reconceived as moments of embodied being within affective flows of popular culture that might momentarily extend upon ways of being and doing girlhood.

Health Information Literacy and the Experience of 65 to 79 Year Old Australians

Information literacy is presented here from a relational perspective, as people’s experience of using information to learn in a particular context. A detailed practical example of such a context is provided, in the health information literacy experience of 65–79 year old Australians. A phenomenographic investigation found five qualitatively distinct ways of experiencing health information literacy: Absorbing (intuitive reception), Targeting (a planned process), Journeying (a personal quest), Liberating (equipping for independence) and Collaborating (interacting in community). These five ways of experiencing indicated expanding awareness of context (degree of orientation towards their environment), source (breadth of esteemed information), beneficiary (the scope of people who gain) and agency (amount of activity), across HIL core aspects of information, learning and health. These results illustrate the potential contribution of relational information literacy to information science.

Found in translation : debating the abstract elements of cultures through actor training styles

While the synthesis of acting methodologies in intercultural acting has been discussed at length, little discussion has focussed on the potential of diverse actor training styles to affect performance making and audience reception. This article explores a project where the abstract elements of the British and American cultures were translated in rehearsal and in production through the purposeful juxtaposition of two differing actor training styles: the British ‘traditional’ approach and the American Method. William Nicholson’s Shadowlands was produced by Crossbow Productions at the Brisbane Powerhouse in 2010. Nicholson’s play contains a discourse on the cultural cringe of British – American relations. As a research project, the production aimed to extend and augment audience experience of the socio-cultural tensions inherent in the play by juxtaposing two seemingly culturally inscribed approaches to acting. Actors were chosen who had been trained under a traditional conservatoire approach and the American Method. A brief overview of these acting approaches is followed by a discussion centred on the project. This article analyses how from the casting room to the rehearsal room to the mise en scene and into the audience discussions, cultural issues were articulated, translated and debated through the language of acting.

‘Crack in the pavement’ : pedagogy as political and moral practice for educating culturally competent professionals

This paper explores the reception of Indigenous perspectives and knowledges in university curricula and educators’ social responsibility to demonstrate cultural competency through their teaching and learning practices. Drawing on tenets of critical race theory, Indigenous standpoint theory and critical pedagogies, this paper argues that the existence of Indigenous knowledges in Australian university curricula and pedagogy demands personal and political activism (Dei, 2008) as it requires educators to critique both personal and discipline-based knowledge systems. The paper interrogates the experiences of non-Indigenous educators involved in this contested epistemological space (Nakata, 2002), and concludes by arguing for a political and ethical commitment by educators towards embedding Indigenous knowledges towards educating culturally competent professionals.

An efficient proactive route maintenance process for reliable data transmissions in sensor networks

For industrial wireless sensor networks, maintaining the routing path for a high packet delivery ratio is one of the key objectives in network operations. It is important to both provide the high data delivery rate at the sink node and guarantee a timely delivery of the data packet at the sink node. Most proactive routing protocols for sensor networks are based on simple periodic updates to distribute the routing information. A faulty link causes packet loss and retransmission at the source until periodic route update packets are issued and the link has been identified as broken. We propose a new proactive route maintenance process where periodic update is backed-up with a secondary layer of local updates repeating with shorter periods for timely discovery of broken links. Proposed route maintenance scheme improves reliability of the network by decreasing the packet loss due to delayed identification of broken links. We show by simulation that proposed mechanism behaves better than the existing popular routing protocols (AODV, AOMDV and DSDV) in terms of end-to-end delay, routing overhead, packet reception ratio.

Representing Death in the News : Journalism, Media and Mortality

Recent years have seen a renewed interest in the relationship between the news, media and death. Driven by a perceived ubiquity of death and dying on television, in newspapers and on the internet, many scholars have attempted to more closely examine aspects of this coverage. The result is that there now exists a large body of scholarly work on death in the news, yet what has been lacking is a comprehensive synthesis of the field. This book seeks to close this gap by analyzing the scholarship on death in the news by way of a thematic approach. It provides a historical overview, looks at the conditions of production, content and reception, and also analyzes emerging trends in the representation of death online. This fascinating account provides a much needed overview of what we currently know about death in the news and provides food for thought for future studies in the field.

Rodent Scope: A User-Configurable Digital Wireless Telemetry System for Freely Behaving Animals

This paper describes the design and implementation of a wireless neural telemetry system that enables new experimental paradigms, such as neural recordings during rodent navigation in large outdoor environments. RoSco, short for Rodent Scope, is a small lightweight user-configurable module suitable for digital wireless recording from freely behaving small animals. Due to the digital transmission technology, RoSco has advantages over most other wireless modules of noise immunity and online user-configurable settings. RoSco digitally transmits entire neural waveforms for 14 of 16 channels at 20 kHz with 8-bit encoding which are streamed to the PC as standard USB audio packets. Up to 31 RoSco wireless modules can coexist in the same environment on non-overlapping independent channels. The design has spatial diversity reception via two antennas, which makes wireless communication resilient to fading and obstacles. In comparison with most existing wireless systems, this system has online user-selectable independent gain control of each channel in 8 factors from 500 to 32,000 times, two selectable ground references from a subset of channels, selectable channel grounding to disable noisy electrodes, and selectable bandwidth suitable for action potentials (300 Hz–3 kHz) and low frequency field potentials (4 Hz–3 kHz). Indoor and outdoor recordings taken from freely behaving rodents are shown to be comparable to a commercial wired system in sorting for neural populations. The module has low input referred noise, battery life of 1.5 hours and transmission losses of 0.1% up to a range of 10 m.

Co-creative media in remote Indigenous communities

This paper examines co-creative video outputs that have originated from, or relate to, remote Indigenous communities in Australia. Scholarly work on remote media has mostly operated at the interface of media studies and anthropology, seeking to identify how cultural systems shape the production, distribution and reception of media in Aboriginal communities. This paper looks instead at content themes, funding sources and institutions during the 2010-2013 period, and examines the factors that may be determining the quantity of co-creative outputs, as well as the types of stories that get produced. I argue that the focus on culture has obscured important shifts in remote media policy and funding, including a trend towards content designed to address social disadvantage.

More than a backchannel : Twitter and television

Twitter is a social media service that has managed very successfully to embed itself deeply in the daily lives of its users. Its short message length (140 characters), and one-way connections (‘following’ rather than ‘friending’), lead themselves effectively to random and regular updates on almost any form of personal or professional activity. Thus, it has found uses from the interpersonal (e.g. Boyd et al., 2010) through crisis communication (e.g. Bruns et al., 2012), to political debate (e.g. Burgess & Bruns, 2012). In such uses, Twitter does not necessarily replace existing media channels, such as broadcasting or online mainstream media, but often complements them, providing its users with alternative opportunities to contribute more actively to the wider media sphere. This is true especially where Twitter is used alongside television, as a simple backchannel to live programming or for more sophisticated uses. In this article, we outline four aspects and dimensions, of the way that the old medium of television intersects, and in some cases, interacts with the new medium of Twitter. Tweeting about the television has always been a social media form. It has also consistently provided key ‘talking points’ for western societies...

Broadcast anti-jamming systems

In a traditional anti-jamming system a transmitter who wants to send a signal to a single receiver spreads the signal power over a wide frequency spectrum with the aim of stopping a jammer from blocking the transmission. In this paper, we consider the case that there are multiple receivers and the transmitter wants to broadcast a message to all receivers such that colluding groups of receivers cannot jam the reception of any other receiver. We propose efficient coding methods that achieve this goal and link this problem to well-known problems in combinatorics. We also link a generalisation of this problem to the Key Distribution Pattern problem studied in combinatorial cryptography.
