A Taylor Model Based Description of the proof stress of magnesium AZ31 during hot working

A series of hot-compression tests and Taylor-model simulations were carried out with the intention of developing a simple expression for the proof stress of magnesium alloy AZ31 during hot working. A crude approximation of wrought textures as a mixture of a single ideal texture component and a random background was employed. The shears carried by each deformation system were calculated using a full-constraint Taylor model for a selection of ideal orientations as well as for random textures. These shears, in combination with the measured proof stresses, were employed to estimate the critical resolved shear stresses for basal slip, prismatic slip, ⟨c+a⟩ second-order pyramidal slip, and { } twinning. The model thus established provides a semianalytical estimation of the proof stress (a one-off Taylor simulation is required) and also indicates whether or not twinning is expected. The approach is valid for temperatures between ∼150 °C and ∼450 °C, depending on the texture, strain rate, and strain path.

Testing the design for Web-based electronic services acceptance model (E-SAM)

This paper reports on the design and testing of a model, which evaluates the relationship components of a Web-based EServices Acceptance Model (E-SAM). The paper proposes that user experience, user motivation, perceived usefulness, perceived ease of use that may determine user acceptance of web-based eServices. The model is tested in a university environment where students and staff use services that have moved from an old paper-based to Web-based eService system. The results of data analysis highlight that user experience is strongly related to perceived ease of use; and perceived usefulness to user motivation in user acceptance of Web-based eServices. The strength of these relationships and the lack of strong relationships between other components suggest that the model's application to eServices is able to highlight the complexity of the eService process and the need for researchers to seek additional components in studying technology acceptance on the World Wide Web.

Evaluating a strategic approach to professional development through guided reflection

Research on quality in early childhood has consistently shown that staff are the cornerstone of excellence, and that staff training makes a difference to services provided to children and families. There is also a growing awareness of the importance of adopting a planned approach to career development and that this begins with self-assessment, and can be enhanced through the use of guided reflection with a mentor. The Early Childhood Consortium Victoria (ECCV) at The University of Melbourne, has developed a self-assessment manual (SAM) designed as a tool for early childhood practitioners to explore their work in a strategic way. It serves the dual purposes of assisting practitioners to address issues of service quality, as well as promoting individual professional development through reflective practice. SAM has now been piloted in a number of early childhood settings in Australia and this paper presents a formative evaluation of this work and discusses its potential for professional development planning.

Play it again, Sam : How journalists cashed in on Youtube's favourite koala

The world was captivated when footage of a badly burnt koala drinking water from a Victorian firefighter's bottle was uploaded to You Tube in February 2009. When the story of "Sam the Koala" was adopted by the mainstream media, recombinant themes were used to construct her story - from heroism and patriotism to villain vs victim and romance. While scholars have examined the changing role of the journalist in a converged world and the rise of "soft" news, this paper focuses on the way journalists create disjointed narratives around You Tube footage to extend a story s lifespan. We call these new narrative forms "fractured fairy tale news" to describe this emerging phenomenon of convergence culture. Further, we suggest that news media exploit the YouTube community for their own commercial gain and conclude that the fractured fairy tale style is a poor vehicle for the future of news.

Study on thermooxidative degradation of poly(vinyl alcohol)/silica nanocomposite prepared with SAM technique

The thermooxidative degradation of poly (vinyl alcohol)/silica (PVA/SiO2) nanocomposite prepared with self-assembly monolayer (SAM) technique is investigated by using a thermogravimetry (TG) and Fourier transform infrared spectroscopy coupled thermogravimetry (FTIR/TG). The results show that although the thermooxidative degradation process of prepared nanocomposite is similar to that of the pure PVA, its thermooxidative stability has been greatly improved.

In the tracks of Blinky Bill : How Sam the koala led news journalists into an Australian literary tradition

The world was captivated when footage of a badly burnt koala taking water from a Victorian Country Fire Authority volunteer was taken with a mobile phone and broadcast to the world on YouTube in February 2009. When the story of ‘Sam the Koala’ was subsequently adopted by traditional broadcast and print media, recombinant themes were used to construct her story – from heroism, patriotism, villain v victim - even romance was incorporated to entertain and create audience appeal. This paper explores how ‘Sam the Koala’ became a defining news story in the coverage of Victoria’s Black Saturday bushfires and examines the power of narrative when cross pollination occurs between new and traditional media in the production of news. It is argued that Sam’s story is evidence of journalists adopting new approaches to storytelling in a bid to retain their legitimacy as the authoritative voice of news and information in an increasingly technologically driven society.
