The current social climate of heightened intercultural tensions in culturally pluralist societies such as Australia highlights the need to develop a more nuanced understanding of the complex cultural adjustment processes  encountered by migrant youth in developing and articulating a sense of  national belonging, To this end, this chapter examines migrant settlement experiences as a 'process by which individuals and groups ... maintain their cultural identity while actively participating in the larger societal framework' (Karac 2001). Research into these critical aspects of integration and  acculturation examines identity formation as a cultural process of  renegotiating individual and group identity, and focuses on concepts of belonging, recognition and self-respect (Berry '997). While cultural factors are considered critical indicators of successful integration into the host community, insufficient research has been conducted into the particular processes of group and individual identity formation that take place amongst migrant youth. In the case of Australia, this process has been made  particularly difficult for some cultural groups due to the contemporary resurgence of populist and exclusionary discourses of national identity. In such a context, the construction of identity amongst migrant youth is all the more challenging, especially when this process exhibits notions of dual attachment, hybridity and difference. For migrant youth, the engagement with different social institutions such as family, school and wider societal networks often affects the processes of identity 'formation that are inherently  dynamic and 'necessarily multiple and fluid' (Noble & Tabar 2002, pp.I28). Negotiating life in-between cultures, youths from migrant backgrounds experience identity construction as a highly contested territory.

Cultural identity is a central issue for immigrants, regardless of how much time has elapsed since leaving their country of origin. This issue is particularly salient for first- and second-generation1 migrant youth, who negotiate identity space comfortably alongside, in opposition to, or more commonly, somewhere in between, their immigrant parents' conceptions of culture and the receiving culture in which they live. Unlike their native peers,  the children of immigrants arc exposed to intra-ethnic and inter- ethnic   dynamics and experiences in their journey towards cultural identity formation. These experiences are complex and diverse, and are navigated within multi- layered ethnic, racial, familial, gendered, socioeconomic and educational  contexts.

The chapter begins by providing theoretical frameworks for conceptualising  cultural diversity and cultural identity. It then examines how migrant youth  negotiate cultural identity in the public realms of family networks and school  environments and how these translate into key educational and behavioural  outcomes. It will draw on some qualitative snapshots as a way of illustrating  shifting migrant youth attitudes towards society, school and culture.

This paper considers the role of animal rights-based Australian law in journalism studies and its connection to instruction of graduate students at a large university based in Victoria. Its case study examples illustrate and develop some of the discussions in journalism studies worldwide of the balance between ethical practice balanced against legal considerations, and whether advocacy and journalism can function together for the benefit of the public interest.

In Australia, the suburbs have historically been the favoured place to raise children. However this is being challenged both by social change and government policy encouraging innerurban renewal. We examined how inner-urban areas compare with more traditional suburban locations as places to raise a family. Recognising that there are many influences on perceptions of place, we included the opinions of parents, service-providers and the media in the two locations.

Research focused on two municipalities in Melbourne, one located >25km and the other <10km from the CBD. Themes were obtained and compared from in-depth interviews with parents, serviceproviders and analysis of municipality-specific and state-wide newspaper articles.

Service provision was the only theme common at all levels of analysis. For all other themes, differences occurred between perspectives of service-providers, media and parents, as well as between the two residential locations. These in-depth snapshots on the challenges and rewards of raising children in different urban locations can help inform government in planning healthy neighbourhoods that better serve the needs of contemporary Australian families.

In this paper we discuss the problem of how to discriminate moments of interest on videos or live broadcast shows. The primary contribution is a system which allows users to personalize their programs with previously created media stickers-pieces of content that may be temporarily attached to the original video. We present the system's architecture and implementation, which offer users operators to transparently annotate videos while watching them. We offered a soccer fan the opportunity to add stickers to the video while watching a live match: the user reported both enjoying and being comfortable using the stickers during the match-relevant results even though the experience was not fully representative.

This thesis is focused on the study of techniques that allow to have reliable transmission of multimedia content in streaming and broadcasting applications, targeting in particular video content. The design of efficient error-control mechanisms, to enhance video transmission systems reliability, has been addressed considering cross-layer and multi-layer/multi-dimensional channel coding techniques to cope with bit errors as well as packet erasures. Mechanisms for unequal time interleaving have been designed as a viable solution to reduce the impact of errors and erasures by acting on the time diversity of the data flow, thus enhancing robustness against correlated channel impairments. In order to account for the nature of the factors which affect the physical layer channel in the evaluation of FEC schemes performances, an ad-hoc error-event modeling has been devised. In addition, the impact of error correction/protection techniques on the quality perceived by the consumers of video services applications and techniques for objective/subjective quality evaluation have been studied. The applicability and value of the proposed techniques have been tested by considering practical constraints and requirements of real system implementations.

Outside lobbying is a key strategy for social movements, interest groups and political parties for mobilising public opinion through the media in order to pressure policymakers and influence the policymaking process. Relying on semi-structured interviews and newspaper content analysis in six Western European countries, this article examines the use of four outside lobbying strategies – media-related activities, informing (about) the public, mobilisation and protest – and the amount of media coverage they attract. While some strategies are systematically less pursued than others, we find variation in their relative share across institutional contexts and actor types. Given that most of these differences are not accurately mirrored in the media, we conclude that media coverage is only loosely connected to outside lobbying behaviour, and that the media respond differently to a given strategy when used by different actors. Thus, the ability of different outside lobbying strategies to generate media coverage critically depends on who makes use of them.
