Current developments and future challenges for the creation of aortic heart valve

The concept of tissue-engineered heart valves offers an alternative to current heart valve replacements that is capable of addressing shortcomings such as life-long administration of anticoagulants, inadequate durability, and inability to grow. Since tissue engineering is a multifaceted area, studies conducted have focused on different aspects such as hemodynamics, cellular interactions and mechanisms, scaffold designs, and mechanical characteristics in the form of both in vitro and in vivo investigations. This review concentrates on the advancements of scaffold materials and manufacturing processes, and on cell–scaffold interactions. Aside from the commonly used materials, polyglycolic acid and polylactic acid, novel polymers such as hydrogels and trimethylene carbonate-based polymers are being developed to simulate the natural mechanical characteristics of heart valves. Electrospinning has been examined as a new manufacturing technique that has the potential to facilitate tissue formation via increased surface area. The type of cells utilized for seeding onto the scaffolds is another factor to take into consideration; currently, stem cells are of great interest because of their potential to differentiate into various types of cells. Although extensive studies have been conducted, the creation of a fully functional heart valve that is clinically applicable still requires further investigation due to the complexity and intricacies of the heart valve.

Work choices : Increasing productivity, job creation and work-family balance? Not likely!

The introduction of the Workplace Relations (Work Choices) Amendment Act 2005 (Cth) has resulted in one of the most contentious changes to federal labour law in Australia’s history. There is considerable debate as to whether it has fulfilled the government’s expectations of giving ‘flexibility’ and ‘choice’ to both employees and employers or if there has been an overall deterioration in working conditions. In order to identify the impact of this legislation in the workplace, Deakin University surveyed 11,000 AHRI members throughout Australia. Preliminary results are reported in the paper but, even at this early stage, there is sufficient material to critically comment upon the changes to Australia’s industrial relations system. It appears that the vast majority of AHRI members felt that there had been no change in productivity, job creation or work-family balance and that only a few expected an improvement over the next 3 years.

'Energetic space' : literary experience and learning

This essay is part of an interdisciplinary research project into literary aesthetics and its relationship with pedagogy. The paper brings cognitive and evolutionary scientific perspectives to bear on literary and cultural theory to address the aesthetic effect (defined as the transporting and transformative power of the literary text) and its potential personal or civic benefits. The paper offers non-transcendentalist explanations for the aesthetic experience, viewing it less as a privileged category of feeling than as an experience available to all symbolic beings. The paper also proposes an original thesis about the virtual and transformative space of reading as one that ultimately epitomises intellectual freedom. The inquiry is lent urgency by the current cultural and political climate in which not only literature but also literary studies, despite its long association with education and its prominent place in the Culture Wars, is in institutional decline.

Virtual communities of enterprise value creation potential for regional clusters

A new concept Virtual Communities of Enterprise is proferred to explain the nature of knowledge sharing both interpersonally and online, and its potential for creating value for small businesses and their regions. Social capital emerges as an essential pre-requisite for accessing value.

Career in writing : Judah Waten and the cultural politics of a literary career

This thesis examines the literary career of Judah Waten (1911-1985) in order to focus on a series of issues in Australian cultural history and theory. The concept of the career is theorised as a means of bringing together the textual and institutional dimensions of writing and being a writer in a specific cultural economy. The guiding question of the argument which re-emerges in different ways in each chapter is: in what ways was it possible to write and to be a writer in a given time and place? Waten's career as a Russian-born, Jewish, Australian nationalist, communist and realist writer across the middle years of this century is, for the purposes of the argument, at once usefully exemplary and usefully marginal in relation to the literary establishment. His texts provide the central focus for individual chapters; at the same time each chapter considers a specific historical moment and a specific set of issues for Australian cultural history, and is to this extent self-contained. Recent work in narrative theory, literary sociology and Australian literary and cultural studies is brought together to revise accepted readings of Waten's texts and career, and to address significant absences or problems in Australian cultural history. The sequence of issues shaping Waten's career in writing is argued in terms of the following conjunctions of theoretical and historical categories: proletarianism, modernity and theories of the avant-garde; the "e;migrant"e; writer and minority literatures; realism, political purpose and narrative self-situation; communism, nationalism and literary practice in the cold war; utopianism and the "e;literary witness"e; narrative of the Soviet Union; assimilationism, multicultural theory and the "e;non-Anglo-Celtic"e; writer; theories of autobiographical writing, and autobiography in Waten's career. The purpose of the thesis is not to discover a single key to Waten's writing across the oeuvre but rather to plot the specific occasions of this writing in the context of the structure of a career and the cultural institutions within which it was formed.

Knowledge creation in an application domain : a hermeneutic study

In this paper we discuss a special case of knowledge creation (pattern mining) that was studied using a hermeneutic circle. Hermeneutics assists the oscillation between tacit and explicit knowledge through the process of knowledge qualification, combination, socialization, externalization, internalization and introspection. Our investigation of the knowledge creation process lead to the enrichment of the knowledge creation framework proposed by Wickramasinghe and Lichtenstein, allowing us to reflect on activities and aspects of knowledge elicitation across an application domain and involving practitioners who do not communicate directly.

Co-creation in the heritage sector

This conceptual paper aims to contribute to current services marketing, service-dominant logic and co-creation literature by investigating the co-creation of experiences and conceptualizing it in terms of three dimensions. A conceptual model is developed in the context of the heritage sector, with each of the three proposed dimensions discussed in-depth.

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.

Automated parallel application creation and execution tool for clusters

This research investigated an automated approach to re-writing traditional sequential computer programs into parallel programs for networked computers. A tool was designed and developed for generating parallel programs automatically and also executing these parallel programs on a network of computers. Performance is maximized by utilising all idle resources.

Only thin smoke without flame

Hardy's short stories have been relatively neglected by critics. This thesis argues for their reconsideration and proper recognition as essential components of Hardy's achievement. Examines his creation of a fictional "Wessex" with himself as conservator, but suggests that their subversive ideologies touching on modern themes, make him a "proto-modern" writer.
