Exposing young children to music through the production and presentation of music-appreciation television programs

This paper reports on a research study of the effectiveness of a series of music-appreciation activities for young children in Hong Kong. These activities were designed using world music and were presented as part of a local early childhood television program for community interest. One-undred-and-sixty-eight local preschool children (mean age 4.25) and their classroom teachers, from 16 childcare centres or kindergartens, participated in this study. Qualitative data was collected using individual structured interviews with both children and teachers. The data showed that these music-appreciation activities enriched children's musical experiences and teachers' musical repertoires in early childhood settings. Teachers also showed positive preferences to learn the activities using multimedia tools. Implications for the curriculum planning and teacher training of early childhood music education are discussed.

Supergirl scorned : lessons about young femininity in an Australian television satire

In this paper I explore the popular Australian television character of Ja’mie King – a teenage private school girl created and performed by male comedian Chris Lilley. I conceptualise Lilley’s satire as a public pedagogy of young femininity. My reading of his satire responds to recent feminist scholarship around young femininities and ‘girl power’, which explores representations of young femininity in popular culture in Western nations. Drawing primarily on the 2005 television mockumentary We can be heroes, I explore how King can be read in terms of exaggerated ‘girl power’ subjectivity. I examine the relationships, fashioned through the character of King, between ‘sexuality’ and global citizenship activity. I consider the extent to which King’s character teaches that young women can ‘have it all’. I explore the extent to which her character teaches that they can be ‘beautiful’ and ‘brainy’, ‘self-determined’ and ‘sexy’ at the same time.

Multiplatform innovation and participatory citizenship : the Australian Broadcasting Corporation’s digital children’s television projects

This paper examines children’s multiplatform commissioning at the Australian Broadcasting Corporation (ABC) in the context of the digitalisation of Australian television. A pursuit of audience share and reach to legitimise its recurrent funding engenders a strategy that prioritises the entertainment values of the ABC’s children’s offerings. Nevertheless, these multiplatform texts (comprising complementary ‘on-air’ and ‘online’ textualities) evidence a continuing commitment to a youth-focussed, public service remit, and reflect the ABC’s Charter obligations to foster innovation, creativity, participation, citizenship, and the values of social inclusiveness. The analysis focuses on two recent ‘marquee’ drama projects, Dance Academy (a contemporary teen series) and My Place (a historical series for a middle childhood audience). The research draws on a series of research interviews, analysis of policy documents and textual analysis of the television and multiplatform content. The authors argue that a mixed diet of programming, together with an educative or social developmental agenda, features in the design of both program and online participation for the public broadcaster.

Foreign correspondents and fixers: an investigation of teamwork in international television newsgathering

This thesis considers the relationship between television foreign correspondents and their locally-hired 'fixers' in order to ascertain the centrality and significance of this relationship in facilitating international news production. The design of this research project, with its emphasis on news production practice, was guided by scholars in the sociology of news tradition, such as Jeremy Tunstall, Michael Schudson, Stephen Reese, Pamela Shoemaker and Simon Cottle. The main research question asks to what extent, and how, is the relationship between the correspondent and the fixer important to newsgathering? Drawing on the theories of Pierre Bourdieu concerning the journalistic field and the acquisition of cultural capital, this research demonstrates how fixers possess vital stores of capital which foreign correspondents borrow in order to be successful in the field. This thesis explores in depth how the players work in tandem to overcome the difficulties posed by multi-skilling, parachuting, instant live reporting, and the 24-hour news cycle. Current newsgathering practice in Iraq is investigated as a case study, which reveals the difficulties of reporting from this dateline and reflects on how the level of danger has changed the nature of the correspondent-fixer relationship. Within this relationship, where a correspondent has the ultimate power to hire and fire, a fixer nonetheless brings significant influence to bear on story generation and story coverage. But does this influence bring into the Western news agenda stories that genuinely reflect localised, indigenous viewpoints? Or, in this globalised world, are fixers simply 'People Like Us' (PLU), who have absorbed Western news values and will reinforce them through the stories that they propose? In other words, are correspondents likely to gain an insight into localised communities and their problems that they might not otherwise have understood, or will they have their own views and presumptions reflected back at them? This thesis examines what the use of fixers reveals about the political economy of news and the changing context of international news production. It asks whether the growing importance of fixers in newsgathering reflects a move by media companies to eventually outsource international newsgathering to local employees. This thesis employs a qualitative methodological approach involving semi-structured interviews with foreign correspondents and fixers to explore their modus operandi and to investigate the building of overseas news teams.

One image reduction algorithm for RGB color images

We investigate the problem of combining or aggregating several color values given in coding scheme RGB. For this reason, we study the problem of averaging values on lattices, and in particular on discrete product lattices. We study the arithemtic mean and the median on product lattices. We apply these aggregation functions in image reduction and we present a new algorithm based on the minimization of penalty functions on discrete product lattices.

Color image magnification with interval-valued fuzzy sets

In this work we present a simple magnification algorithm for color images. It uses Interval-Valued Fuzzy Sets in such a way that every pixel has an interval membership constructed from its original intensity and its neighbourhood's one. Based on that interval membership, a block is created for each pixel, so this is a block expansion method.

Mediators of longitudinal associations between television viewing and eating behaviours in adolescents

Background: Television viewing has been associated with poor eating behaviours in adolescents. Changing unhealthy eating behaviours is most likely to be achieved by identifying and targeting factors shown to mediate the association between these behaviours. However, little is known about the mediators of the associations between television viewing and eating behaviours. The aim of this study was to examine mediators of the longitudinal associations between television viewing (TV) and eating behaviours among Australian adolescents.
Method: Eating behaviours were assessed using a web-based survey completed by a community-based sample of 1729 adolescents from years 7 and 9 of secondary schools in Victoria, Australia, at baseline (2004-2005) and two years later. TV viewing and the potential mediators (snacking while watching TV and perceived value of TV viewing) were assessed via the web-based survey at baseline.
Results: Adolescents who watched more than two hours of TV/day had higher intakes of energy-dense snacks and beverages, and lower intakes of fruit two years later. Furthermore, the associations between TV viewing and consumption of energy-dense snacks, energy-dense drinks and fruit were mediated by snacking while watching TV. Perceived value of TV viewing mediated the association between TV viewing and consumption of energy-dense snacks, beverages and fruit.
Conclusion: Snacking while watching TV and perceived value of TV viewing mediated the longitudinal association between TV viewing and eating behaviours among adolescents. The efficacy of methods to reduce TV viewing, change snacking habits while watching TV, and address the values that adolescents place on TV viewing should be examined in an effort to promote healthy eating among adolescents.

Application of computational media aesthetics methodology to extracting color semantics in film

Using film grammar as the underpinning, we study the extraction of structures in video based on color using a wide configuration of clustering methods combined with existing and new similarity measures. We study the visualisation of these structures, which we call Scene-Cluster Temporal Charts and show how it can bring out the interweaving of different themes and settings in a film. We also extract color events that filmmakers use to draw/force a viewer's attention to a shot/scene. This is done by first extracting a set of colors used rarely in film, and then building a probabilistic model for color event detection. We demonstrate with experimental results from ten movies that our algorithms are effective in the extraction of both scene-cluster temporal charts and color events.

Visual networking : keeping television on the box

The Australian National Broadband Network (NBN) is the largest infrastructure project ever proposed in Australia (NBN, 2010). Its Fibre to the Home open access network will see a new generation of telecommunications services providing the basis for technologies and services to be combined. Homes connected to the network will have access to new digital media and high-speed internet among other applications. Taking an Australian perspective, this paper focuses on the capacity for fast broadband to allow features and technologies to be combined that were once separate, but now have converged including computing, telephony, free-to-air (FTA) television, direct-to-home satellite broadcasting, radio, and the internet and the implications. Specifically, future services for digital television are going to be more akin to app-based functions that are currently available on mobiles and tablets but on the television screen rather than the PC. Against such a background, this article examines the future of television arguing that faster broadband and internet-enabled televisions to watch movies and shows when it suits the audience are the keys to the television’s survival.
