Additive manufacturing in the cycling industry: mainstream or gimmick?

INTRODUCTION. Additive manufacturing (AM) for various industries has been trailed, prototyped and used in limited production runs (Gibson, 2015). But considering additive manufacturing with metallic materials has been around for over 15 years the penetration into an industry such as cycling that values customisation and progressive design techniques has been quite limited. This case study looks at the potential of and why additive manufacturing has not progressed from concept development and prototyping into production and mainstream. Selective Laser Melting (SLM) additive manufacturing systems mainly use Stainless Steel 316 (SS316) and Titanium 6Al.4V (Ti64) as a baseline material; both these materials are extremely common in the custom and high volume bike industries. For the purposes of this article we will focus on smaller custom bike manufacturers who are typically more agile and open to high levels of customisation in their products. The study finds that whilst a high number of companies will experiment and prototype with additive manufacturing there is little evidence that the design and development process translates to ongoing production for sale to the consumer, this could be due to knowledge of design and fabrication techniques.

Aboriginal palliative care and mainstream services

The Aboriginal person's strong wish to die at home with family, surrounded by their 'country' and in their own community means effective palliative care services must be Aboriginal centred and focused.

Teachers talking difference: teacher education and the poetics of anti-racism

This paper reports on a case study which explores the experiences of two teachers of ethnic difference working in secondary schools in rural Australia. In seeking an alternative way of telling their stories, transcript poems have been constructed from data obtained through semi-structured interviews with the teachers. The poems highlight the teachers' experiences of marginalisation and racism and their responses to their positioning in mainly white Anglo-Australian school communities. The study raises particular concerns about the effects of professional and cultural isolation on young and inexperienced teachers of ethnic difference as well as the need to view teacher education as an important site for the development of greater cultural awareness in "mainstream" teacher education students.

Race as political strategy by US presidential candidates: a case study

Race has played an important part in US presidential politics in contemporary history. Different political parties and candidates have followed covert strategies playing on the prejudices of white voters both cognitively and emotionally by linking racerelated issues to the majority's individual and group interests. This elite discourse carried to the public by the mainstream media, along with media's practices of stereotyping, priming, framing and agenda setting, help to justify racial prejudice, discrimination against minorities and their marginalized status, while maintaining the status quo. Taking the social constructionist position, this case study examines the opinions expressed by a sample of undecided voters selected from different geographic locations at various stages of the 1992 US presidential campaign under the themes 'Candidates' racial prejudice' and 'Race is used as political strategy by candidates.'

Drug education with special needs populations : identifying and understanding the challenges

Students with special developmental needs (e.g. learning disabilities, attentional disorders, intellectual disability, conduct disorders, sensory deficits, acquired brain injury) face particular challenges with respect to academic achievement and psychosocial development, whether they are educated in mainstream settings, special settings, or a combination of these. These groups are typically poorly researched with respect to drug and alcohol use and education, however there is some evidence to indicate that they face an elevated risk of experiencing drug-related harms. The aim of the present paper is to highlight the particular challenges facing this heterogeneous population with respect to access to school-based drug education. Special learning challenges facing such students are described, and some suggestions are provided for researchers and practitioners in the drug education field.

Give us a fair go! Legal obstacles to reporting sport on the internet

As the Internet becomes a mainstream conduit for business and communication, it can no longer be referred to as a “ lawless frontier" (De Zwart 1999, 112). The laws that regulate this environment, however, are not always obvious, particularly to reporters who have to collect stories for online newspapers, which are facing competition from their traditional sources of information. This article uses a case study of on-line sport to examine the legal pitfalls facing journalists reporting on-line.

The transition from pediatric to adult health care services for young adults with a disability : an ethical perspective

Young children with disabilities and their carers or parents tend to form a long-term dependent relationship with a paediatrician throughout childhood At some stage when the young person with a disability reaches early adulthood, the relationship is severed This paper draws upon recent research undertaken by the authors that describes the difficulties experienced by young people with disabilities as they go through the transition from paediatric care to adult mainstream health care services. The purpose of this article is to present the argument that the dependent, paternalistic relationship that tends to exist between young people with disabilities (and/or their carers) and paediatricians throughout childhood does not facilitate the successful negotiation of adult mainstream health care services, nor optimally promote the well-being of these young people with disabilities. It is proposed that the promotion of autonomy (or self-determination) via a well planned transition program will increase the likelihood that young adults with disabilities and/or their carers will be empowered to successfully negotiate the current mainstream health care system in Australia, and will enhance the well-being of young adults with disabilities.

Regimes of risk: the need for a pedagogy for peer groups

Peer groups matter more than we think. In this paper we assert that peer group commitments and affiliations are often the primary social reference in determining the way young people think about and practice risk. It is, we argue, inappropriate to impose adult constructions of risk-taking and anti-social behaviour when trying to assert influence over the decisions and practices young people make in the context of their peers. Prominent in our discussion is a concern that mainstream educational theory and practice focuses disproportionately on the individual and their capacity to make rational and independent choices. We believe that within this individualizing framework, teachers have only a very limited capacity to influence the practices and decisions young people make in the presence of their peers, their friends. To ground this discussion we juxtapose the actions and interactions of two young male peer groups, to highlight their respective constructions of group identity.

Peer groups, power and pedagogy : the limits of an educational paradigm of separation

In contrast to the plethora of literature that suggests that the increasing gulf between teachers and young people is due to the shifting interests and expectations of young people, the focus of this paper is on the roles teachers play in this relationship. Provoking interest is a concern that some of the assumptions that underpin 'mainstream' pedagogic theory and practice might actually contribute, albeit unwittingly, to hardening rather than softening the communication divide. Drawing on an incident that took place between a group of 7–8 year old males in a primary school setting, the authors reveal the limits of a teaching paradigm that encourages teachers to adopt authoritative positions from which to separate and individualise student behaviour. In theoretical terms, they argue that the application of this paradigm asserts an exaggerated notion of agency to individuals in the construction of identity. In practical terms it promotes processes that individualise behaviour as a way of dealing with miscreance. Together these manifest themselves as a 'pedagogy of separation'. The process of building more productive pedagogic relationships, it is concluded, needs to begin with teachers better recognising and engaging with the collective investments of young people.

The effect of intellectual disability on children's recall of an event across different question types

This research examined the performance of 80 children aged 9–12 years with either a mild and moderate intellectual disability when recalling an innocuous event that was staged in their school. The children actively participated in a 30-min magic show, which included 21 specific target items. The first interview (held 3 days after the magic show) provided false and true biasing information about these 21 items. The second interview (held the following day) was designed to elicit the children's recall of the target details using the least number of specific prompts possible. The children's performance was compared with that of 2 control groups; a group of mainstream children matched for mental age and a group of mainstream children matched for chronological age. Overall, this study showed that children with either a mild or moderate intellectual disability can provide accurate and highly specific event-related information. However, their recall is less complete and less clear in response to free-narrative prompts and less accurate in response to specific questions when compared to both the mainstream age-matched groups. The implications of the findings for legal professionals and researchers are discussed.

Police perceptions of interviews involving children with intellectual disabilities: a qualitative inquiry

This study employed a qualitative method to explore the experiences of 20 police officers when interviewing children with intellectual disabilities. Three main themes were interpreted as representing challenges to the officers when interviewing special-needs children: police organizational culture, participants' perceptions of these children as interviewees, and prior information. Participants in this inquiry mentioned poor organizational priority within the police force for child abuse cases and children with intellectual disabilities, as well as inadequate support for interviewing skills development and maintenance. Participants also attempted to equalize these children by interviewing them in the same way as their mainstream peers. Finally, participants viewed interview preparation as influential in determining an interview's successful outcome, but recognized that preparedness could bias their interviewing techniques. Increased attention towards these issues will provide a basis for developing strategies to minimize such challenges and thus improve the quality of interviews with children with intellectual disabilities.

Young children learning about evaporation: a longitudinal perspective

This paper traces the learning pathways over a 4-year period of 12 children learning about evaporation. The findings show the complexity and dependence on context of children's understandings. Detailed transcripts for 2 children are used to demonstrate how understandings of phenomena are framed within a network of personal narratives of self that reflect children's different subjectivities as learners and school children, It is argued that the longitudinal methodology opens up a more complex and nuanced view of children's conceptual learning in school settings than is afforded by cross-sectional studies and that the focus on individuals over time compels a very different construction of the learner than is represented in mainstream conceptual-change literature.

Conceptualising industrial relations in the "risk society"

This paper contrasts the characteristics of different types of modernities, noting the present transition occurring between its simple and reflexive manifestations. It then demonstrates how mainstream industrial relations theories have long been framed by a collectivist 'risk insurance principle '. In combining these two observations the argument is made that theories built around institutional dependencies that rely on the evidence or assumption ofoperable risk insurance principles and collective guardianships of workplace well being make less sense in a world of emerging personal narratives ofchoice and dependency that centre around individuals taking personal responsibility for avoiding or diminishing the risks of their engagement with uncertain labour markets. The discussion concludes by setting out the social and epistemological conditions under which future industrial relations theorising might beframed so as to accommodate these emerging conditions in a manner that is both realistic and relevant.

Construction of gender in computer magazine advertisements : confronting the literature

Previous studies (Sofia, 1998; 2002; Turner & Hovenden, 1997; Weinstein, 1998) discussed the power relations surrounding the advertisements for computers in computing magazines, in particular deconstructing the imagery and text which manifested the dominant digital discourse of power (Millar, 1998). In these studies, the authors found that women were positioned as incapable and impotent users of computers.  The authors examined a number of New Zealand and Australian home computing magazines published in 2003 and 2004, looking for evidence of the gendered nature of technology or examples of any form which would constitute discrimination against women or other identity categories. The purpose of this research was to determine whether previous arguments were still relevant and current, or whether advertisements had changed to accommodate populist understandings of gender and cultural equity, or reflect improved power relations between the sexes. In this paper we have explored the findings of a study, which, although small in scale, raises larger questions concerning the 'new' ways in which issues of gender influence advertising focused on computers. Whilst there has been a significant reduction in overtly sexist texts, hegemonic understandings of masculinity and femininity nevertheless continue to structure mainstream advertisements with women routinely positioned in passive, non-expert or very limited kinds of roles. The extent to which this imagery reflects broader social patterns regarding the re-emergence of traditional portrayals of women and men in the media more generally will be the subject of future studies.
