Film, representation and the exclusion of Aboriginal identity: examples from Australian cinema

Throughout the latter half of the past century cinema has played a significant role in the shaping of the core narratives of Australia. Films express and implicitly shape national images and symbolic representations of cultural fictions in which ideas about Indigenous identity have been embedded. In this paper, exclusionary practices in Australian narratives are analysed through examples of films representing Aboriginal identity. Through these filmic narratives the articulation, interrogation, and contestation of views about filmic representations of Aboriginal identity in Australia is illuminated. The various themes in the filmic narratives are examined in order to compare and contrast the ways in which the films display the operation of narrative closure and dualisms within the film texts.

Tribes and political representation: the case of post-war Iraq

 Ten years have passed since the US-led invasion of Iraq in 2003, and the political scene in Iraq is still blurry. Iraq was promoted to be the democratic example in the Middle East. The US came to Iraq to “create” a democratic system that can be a model for other countries in the region. A major factor in creating such environment is by changing the radical centralised totalitarian regime with a weak state that can give more space to building the civil society in new Iraq (Looney, 2003). Nonetheless, the socio-economic and political indicators of the newly installed political “democratic” system point to notable failures. Apart from poor socio-economic factors, the new political elite has either misused democracy for personal, ethno-sectarian or partisan gains or abused the system to ensure their long lasting presence in the decision making arena. Corruption, disconnection from electorate, poor performance and carelessness of politicians and failing state service provisions have all made citizens question the feasibility of political participation in elections. The electorate seem to have lesser faith in the political parties and blocs whose legitimacy of representation  is at stake. Noticeably, tribes have stepped forward to mobilise people as a non-partisan and independent powerful social structure. They have been active in lobbying the state as well as encouraging their members for active participation. This paper discusses the extent to which Iraqi tribes are involved in political participation. It explores their roles in active citizenship and the way they represent and mobilise their  members. It also probes whether tribes have the influence on shaping the political trajectory in Iraq.

Learning sparse latent representation and distance metric for image retrieval

The performance of image retrieval depends critically on the semantic representation and the distance function used to estimate the similarity of two images. A good representation should integrate multiple visual and textual (e.g., tag) features and offer a step closer to the true semantics of interest (e.g., concepts). As the distance function operates on the representation, they are interdependent, and thus should be addressed at the same time. We propose a probabilistic solution to learn both the representation from multiple feature types and modalities and the distance metric from data. The learning is regularised so that the learned representation and information-theoretic metric will (i) preserve the regularities of the visual/textual spaces, (ii) enhance structured sparsity, (iii) encourage small intra-concept distances, and (iv) keep inter-concept images separated. We demonstrate the capacity of our method on the NUS-WIDE data. For the well-studied 13 animal subset, our method outperforms state-of-the-art rivals. On the subset of single-concept images, we gain 79:5% improvement over the standard nearest neighbours approach on the MAP score, and 45.7% on the NDCG.

A representation construction approach

In this chapter we lay out the principles of an approach to teaching and learning science based on student generation, negotiation and refinement of representations in a guided inquiry process. We first tell the story of how we developed this perspective, building on Chapters 1 and 2, and the research approach that led to these principles. The principles of the representation construction approach are described, then exemplified using detailed analysis of parts of classroom learning sequences on force, and substances. We then give examples of teacher responses and beliefs, and finally provide evidence of student conceptual, and meta-representational learning, from this approach.

The silent witness: art as a mode of representation of voices and visions of how,as a woman, I build borders and bridges in enacting my identit(ies)

Feminist theorists unveil how women negotiate their identities within complex entanglements of social constructs such as race, ethnicity, religious belief and practices, cultural tradition, and values. Feminist artists use subjective experiences that shape representation and performativity in empowering women to have a ‘voice’. In this paper, I focus on ‘breaking silences’ through series of my artworks (as part of my PhD research) that represent self-narratives as subjectivities of life experiences, contingencies, and cultural shifts through migration transitions as new ways of figuration and reflection on such issues. I look through discourses of gender differences, nomadic subjectivity, and new ways of figurations (Braidotti 2011, 10) and the affect theory (Gregg and Seigworth 2010), and the concept of giving ‘voice’ (Berlant 2011). Such discourses frame how I interrogate and represent my gendered identities.

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.

A novel bio-kinematic encoder for human exercise representation and decomposition - Part 1 : Indexing and modelling

Current bio-kinematic encoders use velocity, acceleration and angular information to encode human exercises. However, in exercise physiology there is a need to distinguish between the shape of the trajectory and its execution dynamics. In this paper we propose such a two-component model and explore how best to compute these components of an action. In particular, we show how a new spatial indexing scheme, derived directly from the underlying differential geometry of curves, provides robust estimates of the shape and dynamics compared to standard temporal indexing schemes.
