This paper presents two case studies of marginalised youth experimenting with digital music production in flexible education settings. The cases were drawn from a three-year study of alternative assessment in flexible learning centres that enrol 650+ students who have left formal schooling in Queensland, Australia. The cases are framed in reference to the literature on cultural studies approaches to education and the digital arts. Each case describes the student’s histories, cultural background and experiences, music productions, evidence of learning and re-engagement with education. Findings document how digital music production can re-engage and extend participation among students who have left formal education. They do so by theorising the online judgements and blog comments about the digital music production as a social field of exchange. It also raises critical questions about the adequacy of current approaches to evaluating and accounting for the learning and development of such youth, especially where this has occurred through creative arts and digital production.

Digital human models (DHM) have evolved as useful tools for ergonomic workplace design and product development, and found in various industries and education. DHM systems which dominate the market were developed for specific purposes and differ significantly, which is not only reflected in non-compatible results of DHM simulations, but also provoking misunderstanding of how DHM simulations relate to real world problems. While DHM developers are restricted by uncertainty about the user need and lack of model data related standards, users are confined to one specific product and cannot exchange results, or upgrade to another DHM system, as their previous results would be rendered worthless. Furthermore, origin and validity of anthropometric and biomechanical data is not transparent to the user. The lack of standardisation in DHM systems has become a major roadblock in further system development, affecting all stakeholders in the DHM industry. Evidently, a framework for standardising digital human models is necessary to overcome current obstructions.

This article sets the context for this special themed issue on the 'Korean digital wave' by considering the symbiotic relationship between digital technologies, their techniques and practices, their uses and the affordances they provide, and Korea's 'compressed modernity' and swift industrialisation. It underscores the importance of interrogating a range of groundbreaking developments and innovations within Korea's digital mediascapes, and its creative and cultural industries, in order to gain a complex understanding of one of Australia's most significant export markets and trading partners. Given the financial and political commitment in Australia to a high-speed broadband network that aims to stimulate economic and cultural activity, recent technological developments in Korea, and the double-edged role played by government policy in shaping the 'Korean digital wave', merit close attention from media and communications scholars.

Since censorship was lifted in Korea in 1996, collaboration between Korean and foreign filmmakers has grown in both extent and visibility. Korean films have been shot in Australia, New Zealand and mainland China, while the Korean digital post-production and visual effects firms behind blockbusters infused with local effects have gone on to work with filmmakers from greater China and Hollywood Korean cinema has become known for its universal storylines, genre experimentation and high production values. The number of exported Korean films has increased, as has the number of Korean actors starring in films made in other countries. Korea has hosted major international industry events. These milestones have facilitated an unprecedented international expansion of the Korean film industry. With the advent of the 'digital wave in Korea the film industry's transition to digital production practices this expansion has accelerated Korean film agencies the pillars of the national cinema have played important parts in this internationalisation, particularly in promoting Korean films and filmmakers outside Korea and in facilitating international events in Korea itself Yet, for the most part, projects involving Korean filmmakers working in partnership with filmmakers from other countries are the products of individuals and businesses working outside official channels. That is, they are often better understood as 'transnational rather than 'national' or 'international' projects. In this article, we focus on a range of collaborations involving Korean, Australian, New Zealand and Chinese filmmakers and firms. These collaborations highlight some of the forces that have shaped the digital wave in the Korean film industry, and illustrate the increasingly influential role that the 'digital expertise of Korean filmmakers is playing in film industries, both regionally and around the world.

This working paper reflects upon the opportunities and challenges of designing a form of digital noticeboard system with a remote Aboriginal community that supports their aspirations for both internal and external communication. The project itself has evolved from a relationship built through ecological work between scientists and the local community on the Groote Eylandt archipelago to study native populations of animal species over the long term. In the course of this work the aspiration has emerged to explore how digital noticeboards might support communication on the island and externally. This paper introduces the community, the context and the history of the project. We then reflect upon the science project, its outcomes and a framework empowering the Aboriginal viewpoint, in order to draw lessons for extending what we see as a pragmatic and relationship based approach towards cross-cultural design.

The public apology to the Forgotten Australians in late 2009 was, for many, the culmination of a long campaign for recognition and justice. The groundswell for this apology was built through a series of submissions which documented the systemic institutionalised abuse and neglect experienced by the Forgotten Australians that has resulted, for some, in life-long disadvantage and marginalisation. Interestingly it seems that rather than the official documents being the catalyst for change and prompting this public apology, it was more often the personal stories of the Forgotten Australians that resonated and over time drew out quite a torrent of support from the public leading up to, during and after the public apology, just as had been the case with the ‘Stolen Generation.’ Research suggests (cite) that the ethics of such national apologies only make sense if their personal stories are seen as a collective responsibility of society, and only carry weight if we understand and seek to Nationally address the trauma experienced by such victims. In the case of the Forgotten Australians, the National Library of Australia’s Forgotten Australians and Former Child Migrants Oral History Project and the National Museum’s Inside project demonstrate commitment to the digitisation of the Forgotten Australians’ stories in order to promote a better public understanding of their experiences, and institutionally (and therefore formally) value them with renewed social importance. Our project builds on this work not by making or collecting more stories, but by examining the role of the internet and digital technologies used in the production and dissemination of individuals’ stories that have already been created during the period of time between the tabling of the senate inquiry, Children in Institutional Care (1999 or 2003?) and a formal National apology being delivered in Federal Parliament by PM Kevin Rudd (9 Nov, 2009?). This timeframe also represents the emergent first decade of Internet use by Australians, including the rapid easily accessible digital technologies and social media tools that were at our disposal, along with the promises the technology claimed to offer — that is that more people would benefit from the social connections these technologies allegedly were giving us.

Introduction During a recent study of how parents source information about children‘s early learning, one of us made our first serious foray into a local store licensed to the global chain Toys'R' Us. While walking the aisles, closely observing layout, signage and stock, several things became obvious. Firstly, large numbers of toys were labeled'educational'. Secondly, many toys in that category were intended for children under the age of two years. These were further differentiated as intended for 'babies' or 'infants', and sub-categorized on packaging or shelving using even smaller age increments (e.g. 0-3 months, 12-18 months, and so on). Thirdly, many products were labeled as 'interactive' and 'learning' toys that promised to assist children‘s early learning and development. The activation of some of these toys relied on embedded computer chip technology and promised to 'connect' children with the home television, computer and the Internet. These products were hybrids between a toy and a platform for digital media interaction. Closer inspection of toy packaging and other promotional material suggested that industry had begun to invest heavily in developing highly differentiated children‘s markets for products that yoked together concepts of learning and development, the 'fun toy' that incorporates digital technology, and offline- and online participation. In this chapter we explore the growth of this contemporary cultural phenomenon that now connects books, toys and mobile digital media with children‘s play and learning.

This paper presents a nonlinear gust-attenuation controller to stabilize velocities, attitudes and angular rates of a fixed-wing unmanned aerial vehicle (UAV) in the presence of wind gusts. The proposed controller aims to achieve a steady-state flight condition such that the host UAV can avoid airspace collision with other UAVs during the cruise flight. Based on the typical UAV model capturing flight aerodynamics, a nonlinear Hinf controller is developed with rapid response property in consideration of actuator constraints. Simulations are conducted for the Shadow UAV to verify performance of the proposed controller. Comparative studies with the proportional-integral derivative (PID) controllers demonstrate that the proposed controller exhibits great performance improvement in a gusty environment, making it suitable for integration into the design of flight control systems for cruise flight with safety guarantees.

This work presents two UAS See and Avoid approaches using Fuzzy Control. We compare the performance of each controller when a Cross-Entropy method is applied to optimase the parameters for one of the controllers. Each controller receive information from an image processing front-end that detect and track targets in the environment. Visual information is then used under a visual servoing approach to perform autonomous avoidance. Experimental flight trials using a small quadrotor were performed to validate and compare the behaviour of both controllers

This thesis builds on the scholarship and practical know-how that have emerged from digital storytelling projects around the world with diverse groups of participants in a range of institutions. I have used the results of these projects to explore the opportunities Digital Storytelling workshop practice may hold for women’s participation in the public sphere in Turkey. Through theoretical discussion and practical experimentation, I examine the potential of Digital Storytelling workshop practice as a means to promote agency and self-expression in a feminist activist organisation, focusing in particular on whether Digital Storytelling can be used as a change agent – as a tool for challenging the idea of public sphere in ways that make it more inclusive of women’s participation. The thesis engages with feminist scholarship’s critiques of the public/private dichotomy, as well as the concept of gender, to seek connections with narrative identity in the light of the analysis of the Digital Storytelling workshops and the digital stories that were created in a feminist context. The study on which this thesis is based saw the introduction of Digital Storytelling to Turkey for the first time through workshops in Istanbul and Antakya, conducted in partnership with the feminist activist organisation Amargi Women’s Academy. Applying the principles of feminist post-structuralist discourse analysis as used by Judith Baxter (2003), I examine two sets of data collected in this project. First, I analyse the interactions during the Digital Storytelling workshops, where women from Amargi created their digital stories in a collaborative setting. This is done through participatory observation notes and in-depth interviews with the workshop participants and facilitators. Second, I seek to uncover the strategies that these women used to ‘speak back to power’ in their digital stories, reading these as texts. I conclude that women from the Amargi network used the workshops to create digital content in order to communicate their concerns about issues that can be classified as gender-specific matters. During this process, they also cooperated, established new connections, and at the end of the process even defined new ways of using, circulating and repurposing their digital stories for feminist activism in Turkey. My research thereby contributes equally to feminist discourse analysis, the study of new-media usage and uptake among non-professionals, and the study of media–public sphere interactions in a particular national setting: Turkey. My conclusion indicates that the process of production is as important as the product itself, and from that I am able to draw out some strategies for developing digitally equipped women’s activism in Turkey.

This article addresses in depth the question of whether section 420A of the Corporations Act 2001 (Cth) imposes ‘strict liability’ upon a controller for the failure of an agent or expert to take reasonable care. The weight of existing authority appears to suggest that controllers are liable under s 420A for the carelessness of their agents or expert advisers. However, a closer analysis of the text of the provision and relevant Australian and UK case law demonstrates that this aspect of the statutory construction of s 420A remains very much an open question. This article ultimately contends for a construction of s 420A which requires a controller to adequately supervise and scrutinise, but which does not render a blameless controller strictly liable for all careless acts and omissions of agents and expert advisers.

The authors present a Cause-Effect fault diagnosis model, which utilises the Root Cause Analysis approach and takes into account the technical features of a digital substation. The Dempster/Shafer evidence theory is used to integrate different types of fault information in the diagnosis model so as to implement a hierarchical, systematic and comprehensive diagnosis based on the logic relationship between the parent and child nodes such as transformer/circuit-breaker/transmission-line, and between the root and child causes. A real fault scenario is investigated in the case study to demonstrate the developed approach in diagnosing malfunction of protective relays and/or circuit breakers, miss or false alarms, and other commonly encountered faults at a modern digital substation.

Persistent digital hyperthermia, presumably due to vasodilation, occurs during the developmental and acute stages of insulin-induced laminitis. The objectives of this study were to determine if persistent digital hyperthermia is the principal pathogenic mechanism responsible for the development of laminitis. The potent vasodilator, ATP-MgCl 2 was infused continuously into the distal phalanx of the left forefoot of six Standardbred racehorses for 48h via intra-osseous infusion to promote persistent digital hyperthermia. The right forefoot was infused with saline solution and acted as an internal control. Clinical signs of lameness at the walk were not detected at 0h, 24h or 48h post-infusion. Mean±SE hoof wall temperatures of the left forefoot (29.4±0.25°C) were higher (P<0.05) than those on the right (27.5±0.38°C). Serum insulin (15.0±2.89μIU/mL) and blood glucose (5.4±0.22mM) concentrations remained unchanged during the experiment. Histopathological evidence of laminitis was not detected in any horse. The results demonstrated that digital vasodilation up to 30 °C for a period of 48. h does not trigger laminitis in the absence of hyperinsulinaemia. Thus, although digital hyperthermia may play a role in the pathogenesis of laminitis, it is not the sole mechanism involved.
