Numerical simulation for the 3D seepage flow with fractional derivatives in porous media

In this paper, the numerical simulation of the 3D seepage flow with fractional derivatives in porous media is considered under two special cases: non-continued seepage flow in uniform media (NCSFUM) and continued seepage flow in non-uniform media (CSF-NUM). A fractional alternating direction implicit scheme (FADIS) for the NCSF-UM and a modified Douglas scheme (MDS) for the CSF-NUM are proposed. The stability, consistency and convergence of both FADIS and MDS in a bounded domain are discussed. A method for improving the speed of convergence by Richardson extrapolation for the MDS is also presented. Finally, numerical results are presented to support our theoretical analysis.

Hypercapitalism : an investigation into the relationship between language, new media, and social perceptions of value

Overall, this thesis purports to make two significant contributions to knowledge. The first is a foundational critique of political economy in the context of an emergent global knowledge economy. The second is a method for analysing evaluations in language. The relationships that give coherence to those two contributions are as follows. The widely-heralded emergence of a knowledge economy indicates that more intimate aspects of human activity have become exposed to commodification on a massive scale, specifically, activities associated with thought and language. Correspondingly, more abstract forms of value have developed as the products of thought and language have become dominant commodity forms. Historical investigation shows that value has moved from an objective category in political economy, pertaining to such substances as precious metals and land, to become situated today predominantly in “expert” expressions of language, or more precisely, their institutional contexts of production. These are now propagated and circulated on a global scale. Legal, political, and technological developments are key in the development of new, more abstract forms of labour and value, although the relationships connecting these are neither simple nor direct. They are, however, inseparably related in the trajectories that this thesis describes. Consequently they are dealt with inseparably throughout.

Militarising the body politic : new media as weapons of mass instruction

As militarization of bodies politic continues apace the world over, as military organizations again reveal themselves as primary political, economic and cultural forces in many societies, we argue that the emergent and potentially dominant form of political economic organization is a species of neo-feudal corporatism. Drawing upon Bourdieu, we theorize bodies politic as living habitus. Bodies politic are prepared for war and peace through new mediations, powerful means of public pedagogy. The process of militarization requires the generation of new, antagonistic evaluations of other bodies politic. Such evaluations are inculcated via these mediations, the movement of meanings across time and space, between formerly disparate histories, places, and cultures. New mediations touch new and different aspects of the body politic: its eyes, its ears, its organs, but they are consistently targeted at the formation of dispositions, the prime movers of action.

Review : Why study the media ?

Silverstone’s Why Study the Media? (hereafter WSM) is a dif� cult book to review, especially in such a short space. The content spans millennia of theoretical, analytical and historical perspectives on our media, but is none the less entirely contemporary and relevant in its focus. Silverstone’s perspective is at times elusive because the book sets out, successfully I think, to answer the question posed in the title. But it does so by raising major questions in media studies, important questions, in a way that does not imply quick and easy answers.

Sustaining the sustainable? Developing a practice and problem-led new media praxis

In this chapter I introduce an ecological-philosophical approach to artmaking that has guided my work over the past 16 years. I call this ‘Ecosophical praxis’. To illustrate how this infuses and directs my research methodologies, I draw upon a case study called Knowmore (House of Commons), an emerging interactive installation due for first showings in late 2008. This allows me to tease out the complex interrelationships between research and practice within my work, and describe how they comment upon and model these eco-cultural theories. I conclude with my intentions and hopes for the continued emergence of a contemporary eco-political modality of new media praxis that self-reflexively questions how we might re-focus future practices upon ‘sustaining the sustainable’.

Evolving interactions : agile design for networked media performance

Network Jamming systems provide real-time collaborative performance experiences for novice or inexperienced users. In this paper we will outline the interaction design considerations that have emerged during through evolutionary development cycles of the jam2jam Network Jamming software that employs generative techniques that require particular attention to the human computer relationship. In particular we describe the co-evolution of features and uses, explore the role of agile development methods in supporting this evolution, and show how the provision of a clear core capability can be matched with options for enhanced features support multi-levelled user experience and skill develop.

The getting of wisdom : reflections of a teaching librarian

The shift in focus from teaching to learning in higher education can be paralleled in the shift from bibliographic instruction to information literacy. This move has resulted in a change of role from librarians as service providers to educators. This paper argues that in order to facilitate students' 'getting of wisdom', librarians who design and deliver information literacy programs should see themselves as teachers rather than trainers. It compares the role of the school teacher-librarian with that of the academic teaching librarian. The implications of a dominant training paradigm result in the reduction of information literacy to lower order surface learning. Support for teaching librarians is crucial in changing roles and self-image.

Leading indigenous education in a remote location : reflections on teaching to be "proud and deadly"

This thesis is a critical reflection of the author’s time as a Principal of an Indigenous state school from 2003-2004. The purpose is to reassess the impact of her principalship in terms of the staff, students and Community change that affected learning outcomes at the school and to reanalyse to what actions and to whom positive changes could be attributed. This thesis reflects and identifies, in light of the literature, strategies which were effective in enhancing student learning outcomes. The focus of this thesis was the Doongal State School*, its students, staff and facilities. The author will attempt to draw out theoretical frameworks in terms of: (1) what changed educationally in Doongal State School, (2) what seemed to be important in the Principal’s role, (3) the processes that took place, and (4) the effect of being non- Indigenous and a female. Overall, the author undertook this critical reflection in order to understand and embrace educational practices that will (a) lessen the gap between the academic outcomes achieved by Indigenous and non-Indigenous students, and (b) enhance life choices for Indigenous children. The findings indicate that principal leadership is critical for success in Indigenous schools and is the centrepiece of the models developed to explain improvement at Doongal State School. School factors, Principal Leadership factors, Change factors and factors relating to being a non-Indigenous female principal, which, when implemented, will lead to improved educational outcomes for Indigenous students, have evolved as a result of this thesis. Principal Leadership factors were found to be the enablers for the effective implementation of the key components for success.

Managing hostile environments : journalists and media workers : learning to survive the world's difficult, remote and hostile environments

The aim of this research is to examine the changing nature of risks that face journalists and media workers in the world's difficult, remote and hostile environments, and consider the 'adequacy' of managing hostile environment safety courses that some media organizations require prior to foreign assignments. The study utilizes several creative works and contributions to this area of analysis, which includes a documentary film production, course contributions, an emergency reference handbook, security and incident management reviews and a template for evacuation and contingency planning. The research acknowledges that employers have a 'duty of care' to personnel working in these environments, identifies the necessity for pre-deployment training and support, and provides a solution for organizations that wish to initiate a comprehensive framework to advise, monitor, protect and respond to incidents. Finally, it explores the possible development of a unique and holistic service to facilitate proactive and responsive support, in the form of a new profession of 'Editorial Logistics Officer' or 'Editorial Safety Officer' within media organizations. This area of research is vitally important to the profession, and the intended contribution is to introduce a simple and cost-efficient framework for media organizations that desire to implement pre-deployment training and field-support – as these programs save lives. The complete proactive and responsive services may be several years from implementation. However, this study demonstrates that the facilitation of Managing Hostile Environment (MHE) courses should be the minimum professional standard. These courses have saved lives in the past and they provide journalists with the tools to "cover the story, and not become the story."

The Special Broadcasting Service after 30 years : public service media and new ways of thinking about media and citizenship

This article considers the distinctive ways in which the Special Broadcasting Service (SBS) has evolved over its history since 1980, and how it has managed competing claims to being a multicultural yet broad-appeal broadcaster, and a comprehensive yet low-cost media service. It draws attention to the challenges presented by a global rethinking of the nature of citizenship and its relationship to media, for which SBS is well placed as a leader, and the challenges of online media for traditional public service media models, where SBS has arguably been a laggard, particularly when compared with the Australian Broadcasting Corporation (ABC). It notes recent work that has been undertaken by the author with others into user-created content strategies at SBS and how its online news and current affairs services have been evolving in recent years.

The league of men : masculinity, the media and rugby league football

The rhetoric of masculinity is at melting point in Australian culture. In the nineties, Australian television news and sporting programs have constructed a particularly shrill and insistent form of brash, heterosexual sporting masculinity in football reporting. Against this norm of rippling 'muscularity' and aggressive competition, all so-called aberrant forms of humanity such as women, homosexuals, and men who do not fit into Connell's 'hegemonic masculinity' paradigm have been effectively marginalised and silenced. Class and ethnicity discourses are at best muted, and at worst, ignored in much of the writing about sporting masculinity. While acknowledging the significance of class and ethnicity, this paper explores the nexus between gender, sexuality, the media and League football.
