Australia has had two recent public apologies, one to the ‘ Stolen Generation’ of Aboriginal and Torres Strait Islander Australians and the second to the ‘Forgotten Australians' – people who had been removed from their parents as children and institutionalized. Both acts occurred in time when there was no Internet and peoples’ stories took years to collect and decades for their weight to carry the public momentum required to gain a public apology. Now, in a digital age, the reports and the testimonies held within them are available for all to read on the Internet. We all now know what happened and formal public apologies ensued. Both public apologies also draw attention to an emerging intersection between digital technologies, personal historical stories and public apology. Research has identified the potential of digital narrative, such as digital storytelling3 and videoed oral histories to assist in the production of digital narratives that can help to present the multiple voices and viewpoints of those affected by these subjects co-creatively (Burgess et al, pp.152-153). Not all Australians however have access or the skills to use digital tools so as to benefit from these technologies ⎯ especially Indigenous Australians. While the Federal Government is committed to helping Australians enjoy digital confidence and digital media literacy skills, experience inclusive digital participation and benefit through online engagement (Department of Broadband, communications and the Digital Economy, 2009) there are many initiatives that can also be undertaken locally by State funded institutions, such as libraries to assist. This paper highlights the outcomes of recent empirical projects undertaken at the State Library of Queensland (SLQ) in particular focusing on digital initiatives in Family History practices by Indigenous users, and a digital story project in response to the public apology to the Stolen Generation instigated by SLQ.

Mismatch negativity (MMN) is a component of the event-related potential elicited by deviant auditory stimuli. It is presumed to index pre-attentive monitoring of changes in the auditory environment. MMN amplitude is smaller in groups of individuals with schizophrenia compared to healthy controls. We compared duration-deviant MMN in 16 recent-onset and 19 chronic schizophrenia patients versus age- and sex-matched controls. Reduced frontal MMN was found in both patient groups, involved reduced hemispheric asymmetry, and was correlated with Global Assessment of Functioning (GAF) and negative symptom ratings. A cortically-constrained LORETA analysis, incorporating anatomical data from each individual's MRI, was performed to generate a current source density model of the MMN response over time. This model suggested MMN generation within a temporal, parietal and frontal network, which was right hemisphere dominant only in controls. An exploratory analysis revealed reduced CSD in patients in superior and middle temporal cortex, inferior and superior parietal cortex, precuneus, anterior cingulate, and superior and middle frontal cortex. A region of interest (ROI) analysis was performed. For the early phase of the MMN, patients had reduced bilateral temporal and parietal response and no lateralisation in frontal ROIs. For late MMN, patients had reduced bilateral parietal response and no lateralisation in temporal ROIs. In patients, correlations revealed a link between GAF and the MMN response in parietal cortex. In controls, the frontal response onset was 17 ms later than the temporal and parietal response. In patients, onset latency of the MMN response was delayed in secondary, but not primary, auditory cortex. However amplitude reductions were observed in both primary and secondary auditory cortex. These latency delays may indicate relatively intact information processing upstream of the primary auditory cortex, but impaired primary auditory cortex or cortico-cortical or thalamo-cortical communication with higher auditory cortices as a core deficit in schizophrenia.

Purpose To present the results of tests for the development of literary trails for domestic visitors and tourists in Brisbane, Queensland, and to situate these findings in the context of recent state government policy changes in relation to culture, community engagement and the environment. Design Broadly cultural studies: the article analyses changes in international and national cultural tourism and Queensland based issues before presenting the research findings. Findings a gap in tourist and cultural development models exists for the implementation of a network of sustainable literary trails in Brisbane--this model can be extended to regions around the state to meet the demands of the new tourist. Limitations Queensland weather and Australian distance which will require a regional approach that networks with transport and community hubs. Practical implications the research has produced new software for the use of self-guided walks; the locations for two specific area trails; and the involvement of the State Library of Queensland as a “hub” for the trails. Substantial support exists for further development in advanced locative media and gaming. Social implications the research demonstrates the importance of developing a sense of place that relates to culture, literary history and community for tourists, as well as the potential for community engagement.

Long-term inhalation studies in rodents have presented unequivocal evidence of experimental carcinogenicity of ethylene oxide, based on the formation of malignant tumors at multiple sites. However, despite a considerable body of epidemiological data only limited evidence has been obtained of its carcinogenicity in humans. Ethylene oxide is not only an important exogenous toxicant, but it is also formed from ethylene as a biological precursor. Ethylene is a normal body constituent; its endogenous formation is evidenced by exhalation in rats and in humans. Consequently, ethylene oxide must also be regarded as a physiological compound. The most abundant DNA adduct of ethylene oxide is 7-(2-hydroxyethyl)guanine (HOEtG). Open questions are the nature and role of tissue-specific factors in ethylene oxide carcinogenesis and the physiological and quantitative role of DNA repair mechanisms. The detection of remarkable individual differences in the susceptibility of humans has promoted research into genetic factors that influence the metabolism of ethylene oxide. With this background it appears that current PBPK models for trans-species extrapolation of ethylene oxide toxicity need to be refined further. For a cancer risk assessment at low levels of DNA damage, exposure-related adducts must be discussed in relation to background DNA damage as well as to inter- and intraindividual variability. In rats, subacute ethylene oxide exposures on the order of 1 ppm (1.83 mg/m3) cause DNA adduct levels (HOEtG) of the same magnitude as produced by endogenous ethylene oxide. Based on very recent studies the endogenous background levels of HOEtG in DNA of humans are comparable to those that are produced in rodents by repetitive exogenous ethylene oxide exposures of about 10 ppm (18.3 mg/m3). Experimentally, ethylene oxide has revealed only weak mutagenic effects in vivo, which are confined to higher doses. It has been concluded that long-term human occupational exposure to low airborne concentrations to ethylene oxide, at or below current occupational exposure limits of 1 ppm (1.83 mg/m3), would not produce unacceptable increased genotoxic risks. However, critical questions remain that need further discussions relating to the coherence of animal and human data of experimental data in vitro vs. in vivo and to species-specific dynamics of DNA lesions.

As a Lecturer of Animation History and 3D Computer Animator, I received a copy of Moving Innovation: A History of Computer Animation by Tom Sito with an element of anticipation in the hope that this text would clarify the complex evolution of Computer Graphics (CG). Tom Sito did not disappoint, as this text weaves together the multiple development streams and convergent technologies and techniques throughout history that would ultimately result in modern CG. Universities now have students who have never known a world without computer animation and many students are younger than the first 3D CG animated feature film, Toy Story (1996); this text is ideal for teaching computer animation history and, as I would argue, it also provides a model for engaging young students in the study of animation history in general. This is because Sito places the development of computer animation within the context of its pre-digital ancestry and throughout the text he continues to link the discussion to the broader history of animation, its pioneers, technologies and techniques...

Over the past decades there has been a considerable development in the modeling of car-following (CF) behavior as a result of research undertaken by both traffic engineers and traffic psychologists. While traffic engineers seek to understand the behavior of a traffic stream, traffic psychologists seek to describe the human abilities and errors involved in the driving process. This paper provides a comprehensive review of these two research streams. It is necessary to consider human-factors in {CF} modeling for a more realistic representation of {CF} behavior in complex driving situations (for example, in traffic breakdowns, crash-prone situations, and adverse weather conditions) to improve traffic safety and to better understand widely-reported puzzling traffic flow phenomena, such as capacity drop, stop-and-go oscillations, and traffic hysteresis. While there are some excellent reviews of {CF} models available in the literature, none of these specifically focuses on the human factors in these models. This paper addresses this gap by reviewing the available literature with a specific focus on the latest advances in car-following models from both the engineering and human behavior points of view. In so doing, it analyses the benefits and limitations of various models and highlights future research needs in the area.

From Queensland’s inception as a self-governing colony in December 1859 the issue of labour relations has preoccupied governments and shaped the experiences of its working men and women. However, despite the often turbulent nature of labour relations in Queensland there has, prior to this book, been no attempt to provide an overview of the system as a whole. This important addition to Queensland’s sesquicentenary celebrations redresses this failure, looking at the diverse range of experiences that, together, made up a unique system of labour relations – including those of employers, women workers, indigenous workers, unions, the Queensland Industrial Relations Commission, labour law, industrial disputation, the workings of health and safety system and life in regional areas. It is argued that, overall, Queensland’s system of industrial regulation was central to its economic and social development. Despite past emphasis on the large-scale strikes that periodically raked the state this book finds that consensus normally prevailed.

This paper reports profiling information for speeding offenders and is part of a larger project that assessed the deterrent effects of increased speeding penalties in Queensland, Australia, using a total of 84,456 speeding offences. The speeding offenders were classified into three groups based on the extent and severity of an index offence: once-only low-rang offenders; repeat high-range offenders; and other offenders. The three groups were then compared in terms of personal characteristics, traffic offences, crash history and criminal history. Results revealed a number of significant differences between repeat high-range offenders and those in the other two offender groups. Repeat high-range speeding offenders were more likely to be male, younger, hold a provisional and a motorcycle licence, to have committed a range of previous traffic offences, to have a significantly greater likelihood of crash involvement, and to have been involved in multiple-vehicle crashes than drivers in the other two offender types. Additionally, when a subset of offenders’ criminal histories were examined, results revealed that repeat high-range speeding offenders were also more likely to have committed a previous criminal offence compared to once only low-range and other offenders and that 55.2% of the repeat high-range offenders had a criminal history. They were also significantly more likely to have committed drug offences and offences against order than the once only low-range speeding offenders, and significantly more likely to have committed regulation offences than those in the other offenders group. Overall, the results indicate that speeding offenders are not an homogeneous group and that, therefore, more tailored and innovative sanctions should be considered and evaluated for high-range recidivist speeders because they are a high-risk road user group.
