Distinguishing forced versus discretionary replacements in new product diffusion models

In many product categories of durable goods such as TV, PC, and DVD player, the largest component of sales is generated by consumers replacing existing units. Aggregate sales models proposed by diffusion of innovation researchers for the replacement component of sales have incorporated several different replacement distributions such as Rayleigh, Weibull, Truncated Normal and Gamma. Although these alternative replacement distributions have been tested using both time series sales data and individual-level actuarial “life-tables” of replacement ages, there is no census on which distributions are more appropriate to model replacement behaviour. In the current study we are motivated to develop a new “modified gamma” distribution by two reasons. First we recognise that replacements have two fundamentally different drivers – those forced by failure and early, discretionary replacements. The replacement distribution for each of these drivers is expected to be quite different. Second, we observed a poor fit of other distributions to out empirical data. We conducted a survey of 8,077 households to empirically examine models of replacement sales for six electronic consumer durables – TVs, VCRs, DVD players, digital cameras, personal and notebook computers. This data allows us to construct individual-level “life-tables” for replacement ages. We demonstrate the new modified gamma model fits the empirical data better than existing models for all six products using both a primary and a hold-out sample.

Summary report : the high road or the low road? Alternatives for Australia's future

This document is a summary of the findings of the inaugural study commissioned by the Australian Business Foundation Limited. It was conducted by Professor Jane Marceau, Pro-Vice Chancellor (Research) at the University of Western Sydney Macarthur, Dr Karen Manley, Visiting Research Fellow at the University of Western Sydney Macarthur and Mr Derek Sicklen, Managing Director of Australian Economic Analysis Pty Limited. The full report is available from the Australian Business Foundation. The Australian Business Foundation Limited is a recently formed independent economic and industry policy think-tank. It has been established and sponsored by Australian Business Limited, a pre-eminent and long-standing industry association and business services network. The report is in three parts. The first reviews the key findings of contemporary international economic and innovation-oriented analyses of the characteristics of high growth economies. The second assesses the shape, structure and dynamics of Australian industry as these compare with the characteristics for successful economic development suggested in the literature. Finally, the report indicates the nature of urgently required policy directions.

Doing justice : young people’s representations of the Murray-Darling Basin

The business of helping children to grow up as ‘custodians’, or ‘future managers’ of the Murray-Darling Basin is not simple, and that single sources of information and ways of seeing the environment are not enough. Children (and adults) need to be able to relate individually, emotionally and aesthetically to their places if they are to learn to love them. However, they also need access to a variety of ways of thinking and seeing those same places if they are to be able to take action to sustain them – action that inevitably involves forms of communication with their fellow citizens. This chapter documents the writing and art program Special Forever, with its focus on communications, as an important intervention into promoting eco-social sustainability.

Sustaining the next generation of teacher-researchers to work for social justice

This chapter explores a research project involving teachers working with some of the most disadvantaged young people in South Australia, children growing up in poverty, in families struggling with homelessness and ill-health, in the outer southern suburbs. Additionally, there were particular children were struggling with intellectual, emotional and social difficulties which were extreme enough for them not be included in a mainstream class. The research project made two crucial interrelated moves to support teachers to tackle this tough work. First, the project had an explicit social justice agenda. We were not simply researching literacy outcomes, but literacy pedagogies for the students teachers were most worried about. And we wanted to understand how the material conditions of students’ everyday lifeworlds impacted on the working conditions of teachers’ schoolworlds. We sought to open up a discursive space where teachers could talk about poverty, violence, racism and classism in ways that would take them beyond despair and into new imaginings and positive action. Second, the project was designed to start from the urgent questions of early career teachers and to draw on the accumulated practice wisdom of their chosen mentors. Hence we designed not only a teacher-researcher community, but cross-generational networks. Our aim was to build the capacities of both generations to address long-standing educational problems in new ways that drew overtly on their different and complementary resources.

Acknowledging social justice and equity through good practice for monitoring student learning engagement in FYE

As higher education institutions respond to government targets to widen participation, their student populations will become increasingly diverse, and the issues around student success and retention will be more closely scrutinised. The concept of student engagement is a key factor in student achievement and retention and Australasian institutions have a range of initiatives aimed at monitoring and intervening with students who are at risk of disengaging. Within the widening participation agenda, it is absolutely critical that these initiatives are designed to enable success for all students, particularly those for whom social and cultural disadvantage have been a barrier. Consequently, for the sector, initiatives of this type must be consistent with the concept of social justice and a set of principles would provide this foundation. This session will provide an opportunity for participants to examine a draft set of principles and to discuss their potential value for the participants’ institutional contexts.

Researching for social justice: Contextual, conceptual and methodological challenges

Reforming schooling to enable engagement and success for those typically marginalised and failed by schools is a necessary task for educational researchers and activists concerned with injustice. However, it is a difficult pursuit, with a long history of failed attempts. This paper outlines the rationale of an Australian partnership research project, Redesigning Pedagogies in the North (RPiN), which took on such an effort in public secondary schooling contexts that, in current times, are beset with 'crisis' conditions and constrained by policy rationales that make it difficult to pursue issues of justice. Within the project, university investigators and teachers collaborated in action research that drew on a range of conceptual resources for redesigning curriculum and pedagogies, including: funds of knowledge, vernacular or local literacies; place-based education; the 'productive pedagogies' and the 'unofficial curriculum' of popular culture and out-of-school learning settings. In bringing these resources together with the aim of interrupting the reproduction of inequality, the project developed a methodo-logic which builds on Bourdieuian insights.

Developing a social justice framework to ensure good practice in higher education

As higher education institutions respond to government targets to widen participation, their student populations will become increasingly diverse, and the mechanisms in place to support student success and retention will be more closely scrutinised.

Developing ethical identities in young offenders through restorative justice practice in Australia

Restorative justice is firmly established in Australian juvenile justice. While the official language used to describe restorative initiatives varies across states and territories, the most common form is a meeting or conference between young offenders and their victims (most commonly known as a family group or youth justice conference). During the past decade, an impressive amount of empirical research has examined how the restorative justice process affects offenders, victims and other participants (such as supporters for young offenders and victims). Results from this line of research are remarkably consistent and show that participants generally regard restorative conferences as procedurally fair and that they are satisfied with the outcomes (eg what young offenders agree to do to make up for their offending behaviour, such as offer a sincere apology or perform work for the victim or the community). What is less common, however, is the perception among participants that restorative conferences achieve the key aim of restoration.By ‘restoration’ we refer to encounters where ‘offenders apologise, their apologies are accepted, victims offer forgiveness,and conferences conclude with a feeling of mutual good will’.

Offending Youth : Crime, Sex and Justice

Rates of female delinquency, especially for violent crimes, are increasing in most common law countries. At the same time the growth in cyber-bullying, especially among girls, appears to be a related global phenomenon. While the gender gap in delinquency is narrowing in Australia, United States, Canada and the United Kingdom, boys continue to dominate the youth who commit crime and have a virtual monopoly over sexually violent crimes. Indigenous youth continue to be vastly over-represented in the juvenile justice system in every Australian jurisdiction. The Indigenisation of delinquency is a persistent problem in other countries such as Canada and New Zealand. Young people who gather in public places are susceptible to being perceived as somehow threatening or riotous, attracting more than their share of public order policing. Professional football has been marred by repeated scandals involving sexual assault, violence and drunkenness. Given the cultural significance of footballers as role models to thousands, if not millions, of young men around the world, it is vitally important to address this problem. Offending Youth explores these key contemporary patterns of delinquency, the response to these by the juvenile justice agencies and moreover what can be done to address these problems. The book also analyses the major policy and legislative changes from the nineteenth to twenty first centuries, chiefly the shift the penal welfarism to diversion and restorative justice. Using original cases studied by Carrington twenty years ago, Offending Youth illustrates how penal welfarism criminalised young people from socially marginal backgrounds, especially Aboriginal children, children from single parent families, family-less children, state wards and young people living in poverty or in housing commission estates. A number of inquiries in Australia and the United Kingdom have since established that children committed to these institutions, supposedly for their own good, experienced systemic physical, sexual and psychological abuse during their institutionalisation. The book is dedicated to the survivors of these institutions who only now are receiving official recognition of the injustices they suffered. The underlying philosophy of juvenile justice has fundamentally shifted away from penal welfarism to embrace positive policy responses to juvenile crime, such as youth conferencing, cautions, warnings, restorative justice, circle sentencing and diversion examined in the concluding chapter. Offending Youth is aimed at a broad readership including policy makers, juvenile justice professionals, youth workers, families, teachers, politicians as well as students and academics in criminology, policing, gender studies, masculinity studies, Indigenous studies, justice studies, youth studies and the sociology of youth and deviance more generally.-- [from publisher website]

Post-PC devises : a summary of early iPad technology

In just under 3 months worldwide sales of Apple's iPad tablet device stood at over 3 million units sold. The iPad device, along with rival products signify a shift in the way in which print and other media products are purchased and consumed by users. While facing initial skepticism about the uptake of the device numerous industries have been quick to adapt the device to their specific needs. Based around a newly developed six point typology of “post PC” device utility this project undertook a significant review of publicly available material to identify worldwide trends in iPad adoption and use within the tertiary sector.

Making use of theories about literacy and justice: teachers re-searching practice

This article considers teachers’ work as they grapple with theories in practice in the everyday worlds of their classroom. It argues that Bourdieu’s theory of practice and the concept of habitus may be useful in moving past theory/practice dichotomies. After establishing the historical context for teacher research in South Australia, the work of two school-based literacy educators with an overt social justice standpoint is explored. The complexity of teachers’ intellectual work and identity formation over time is outlined and implications for teacher education are discussed.

Factors that influence Information Systems decisions and outcomes: A summary of key themes from four case studies" (2006). ACIS 2006 Proceedings. Paper 43.

This paper reports a summary of key findings from an examination of Information Systems decision making in four organisations. The study focused on what factors influenced decision makers during the critical preimplementation phase of Information Systems projects when systems were evaluated, selected and acquired. Using data gathered from interviews and organisational documentation, a critical hermeneutic analysis was performed in order to build an understanding of how informational and contextual influences acted on decision makers. Eight broad themes of factors were identified as having influence on decision makers and outcomes.
