Learning through the affordances of representation construction

In this chapter we draw upon several theoretical perspectives and past research into language and learning in science, to develop a framework to characterize how and why student engagement in representation construction practices supports learning in science.

The Victorian bushfires and extreme weather events : media coverage, crisis and communication

The 2009 'Black Saturday' Victorian bushfires claimed the lives of 173 people and have become known as the worst fire event in Australian history. Victoria has been at the centre of two other significant Australian fire disasters - 'Black Friday' in 1939 and the 1983 'Ash Wednesday' fires in south-eastern Australia that claimed the lives of 47 people in Victoria. As media scholar and commentator Michael Gawenda has noted, the media not only report an 'event' - like the Victorian bushfires or the tsunami in the South Pacific - but in a sense create and define it. Print and electronic media coverage of extreme weather events therefore raises a multitude of issues about the media's role in serving the community before, during and after a crisis, while also trying to produce the best possible reportage in a competitive industry undergoing dramatic change. This issue of MIA provides a venue for critical, empirical engagement with media coverage and representation, and the role of journalism and journalists in reporting national and international bushfires, tsunamis, hurricanes and other extreme weather events, with a special focus on the 2009 Victorian bushfires. Its goal is to address the ramifications of an industry in flux - indeed, some may say crisis - driven by technological advances, staff reductions and media organisations under financial pressure, and to explore the ways in which such extreme weather events have impacted media practices and policy

Voice, post-structural representation and the subjectivity of ‘included’ students

Aligned with the broader movement from structuralism to the post-structuralisms [Lather, P. 2013. “Methodology-21: What Do We Do in the Afterward?” International Journal of Qualitative Studies in Education 26 (6): 634–645; St. Pierre, E. A. 2009. “Afterword: Decentering Voice in Qualitative Inquiry.” In Voice in Qualitative Inquiry: Challenging Conventional, Interpretive, and Critical Conceptions in Qualitative Research, edited by A. Y. Jackson and L. A. Mazzei, 221–236. London: Routledge; St. Pierre, E. A. 2013. “The Posts Continue: Becoming.” International Journal of Qualitative Studies in Education 26 (6): 646–657], research in disability studies for the past two decades has found ‘the potholes’ [Miller, L., J. B. Whalley, and I. Stronach. 2012. “From Structuralism to Poststructuralism.” In Research Methods in the Social Sciences, edited by B. Somekh and C. Lewin. London: SAGE] of disability rights scholarship. In this paper, I offer a critical research framework in the field of disability studies in education that is theoretical, political and personal. Concentrating on the positioning of disability, I draw on the methodological tools of post-structural representation, subjectivity and constructivist grounded theory to study how discursive practices within (and around) secondary schools shape ‘included’ disabled subjects. In the paper I develop this framework and then demonstrate its application in ongoing research that critically counters the conventions that marginalize particular students in schools.

Who is he now? The unearthly David Bowie

The question that has led and organised this special edition on David Bowie draws provocative attention to the way his career has been narrated by the constant transformation and recasting of his star image. By asking who is he now? the edition recognises that Bowie is a chameleon figure, one who reinvents himself in and across the media and art platforms that he is found in. This process of renewal means that Bowie constantly kills himself, an artistic suicide that allows for dramatic event moments to populate his music, and for a rebirth to emerge at the same time or shortly after he expires. Bowie has killed Major Tom, Ziggy Stardust, Halloween Jack, Aladdin Sane, and the Thin White Duke to name but a few of his alter-egos. In this environment of death and resurrection, Bowie becomes a heightened, exaggerated enigma, a figure who constantly seems to be artificial or constructed and yet whose work asks us to look for his real self behind the mask – to ask the question, is this now the real Bowie that faces us? Of course, the answer is always no because Bowie is a contradictory constellation of images, stories and sounds whose star image rests on remaining an enigma, and like all stars in our midst, exists as a representation. Nonetheless, with Bowie - with this hyper- schizophrenic, confessional artist – the fan desire to get to know him, to immerse oneself in his worlds, fantasises, and projections - is particularly acute. With the unexpected release of The Next Day ((Iso/Columbia) on the 8th March 2013, the day of his 66th birthday, Bowie was resurrected again. The album and subsequent music videos drew explicitly on the question of who Bowie was and had been, creating a media frenzy around his past work, fan nostalgia for previous Bowie incarnations, and a pleasurable negotiation with his new output. In this special edition, edited by life-long Bowie fans, with contributions from die-hard Bowie aficionados, we seek to find him in the fragments and remains of what once was, and in the new enchantments of his latest work.

Governance, representation and the ‘monstrous regiment’: is the collective feminine?

Alternatives to the individualistic emphasis of liberal theory focus attention on collective dimensions of social life with implications for legal and political analysis of the state, of representation, and of international law. In this context, relationships between the individual–collective dichotomy and the dichotomy of gender demand attention because of the claimed affiliations of individualism with social understandings of masculinity.

Numerical modeling of dual phase microstructure behavior under deformation conditions on the basis of digital material representation

Development of a digital material representation (DMR) model of dual phase steel is presented within the paper. Subsequent stages involving generation of a reliable representation of microstructure morphology, assignment of material properties to component phases and incorporation of the model into the commercial finite element software are described within the paper. Different approaches used to recreate dual phase morphology in a digital manner are critically assessed. However, particular attention is placed on innovative identification of phase properties at the micro scale by using micro-pillar compression tests. The developed DMR model is finally applied to model influence of micro scale features on failure initiation and propagation under loading conditions.

Numerical investigation of influence of the Martensite Volume Fraction on dp steels fracture behavior on the basis of digital material representation model

Development of the methodology for creating reliable digital material representation (DMR) models of dual-phase steels and investigation of influence of the martensite volume fraction on fracture behavior under tensile load are the main goals of the paper. First, an approach based on image processing algorithms for creating a DMR is described. Then, obtained digital microstructures are used as input for the numerical model of deformation, which takes into account mechanisms of ductile fracture. Ferrite and martensite material model parameters are evaluated on the basis of micropillar compression tests. Finally, the model is used to investigate the impact of the martensite volume fraction on the DP steel behavior under plastic deformation. Results of calculations are presented and discussed in the paper.

Migration exhibitions and the question of identity: reflections on the history of the representation of migration in Australian museums, 1986-2011

Museums and Migration explores the ways in which museum spaces - local, regional, national - have engaged with the history of migration, including internal migration, emigration and immigration.

A reassessment of non-union employee representation in the UK: developments since the 'ICE' age

In light of new legislation pertaining to information and consultation in the UK, the need to reassess the realms of employee involvement and participation, especially non-union forms, is critically apparent. This article explores the character of non-union employee representation arrangements established in the context of the Information and Consultation of Employees Regulations 2004, drawing on case study evidence from two UK-based manufacturing organisations. The findings highlight some important dynamics concerning the use of non-union employee representation; not least that the Information and Consultation of Employees Regulations have impacted in very different ways from those anticipated by the legislation.

Assessment of habitat representation across a network of marine protected areas with implications for the spatial design of monitoring

Networks of marine protected areas (MPAs) are being adopted globally to protect ecosystems and supplement fisheries management. The state of California recently implemented a coast-wide network of MPAs, a statewide seafloor mapping program, and ecological characterizations of species and ecosystems targeted for protection by the network. The main goals of this study were to use these data to evaluate how well seafloor features, as proxies for habitats, are represented and replicated across an MPA network and how well ecological surveys representatively sampled fish habitats inside MPAs and adjacent reference sites. Seafloor data were classified into broad substrate categories (rock and sediment) and finer scale geomorphic classifications standard to marine classification schemes using surface analyses (slope, ruggedness, etc.) done on the digital elevation model derived from multibeam bathymetry data. These classifications were then used to evaluate the representation and replication of seafloor structure within the MPAs and across the ecological surveys. Both the broad substrate categories and the finer scale geomorphic features were proportionately represented for many of the classes with deviations of 1-6% and 0-7%, respectively. Within MPAs, however, representation of seafloor features differed markedly from original estimates, with differences ranging up to 28%. Seafloor structure in the biological monitoring design had mismatches between sampling in the MPAs and their corresponding reference sites and some seafloor structure classes were missed entirely. The geomorphic variables derived from multibeam bathymetry data for these analyses are known determinants of the distribution and abundance of marine species and for coastal marine biodiversity. Thus, analyses like those performed in this study can be a valuable initial method of evaluating and predicting the conservation value of MPAs across a regional network.
