A genetic algorithm for the multi-source and multi-sink minimum vertex cut problem and its applications

We present a new penalty-based genetic algorithm for the multi-source and multi-sink minimum vertex cut problem, and illustrate the algorithm’s usefulness with two real-world applications. It is proved in this paper that the genetic algorithm always produces a feasible solution by exploiting some domain-specific knowledge. The genetic algorithm has been implemented on the example applications and evaluated to show how well it scales as the problem size increases.

A study on matching and multi-objective fuzzy control strategy of heavy truck suspension system

Matching method of heavy truck-rear air suspensions is discussed, and a fuzzy control strategy which improves both ride comfort and road friendliness of truck by adjusting damping coefficients of the suspension system is found. In the first place, a Dongfeng EQ1141G7DJ heavy truck’s ten DOF whole vehicle-road model was set up based on Matlab/Simulink and vehicle dynamics. Then appropriate passive air suspensions were chosen to replace the original rear leaf springs of the truck according to truck-suspension matching criterions, consequently, the stiffness of front leaf springs were adjusted too. Then the semi-active fuzzy controllers were designed for further enhancement of the truck’s ride comfort and the road friendliness. After the application of semi-active fuzzy control strategy through simulation, is was indicated that both ride comfort and road friendliness could be enhanced effectively under various road conditions. The strategy proposed may provide theory basis for design and development of truck suspension system in China.

Accidental amenity

Landscape in Australian multi-unit residential developments has passed through a number of phases. Can we make the successes more intentional than serendipitous? When did the block of flats become renamed "multi-unit residential"? Perhaps it coincided with a realization by Australians that medium - and high-density urban housing was neither an attack on the quarter-acre block nor a synonym for public housing. Higher densities allow people to participate in the city, and the expansion of unit-based housing represents Australians' growing love of cities for their urban and cosmopolitan values. As our attitude to the city has changed, so have the types of multi-unit residential stock changed - in their spatial qualities as well as their role in the landscape.

Configurable multi-perspective business process models

A configurable process model provides a consolidated view of a family of business processes. It promotes the reuse of proven practices by providing analysts with a generic modelling artifact from which to derive individual process models. Unfortunately, the scope of existing notations for configurable process modelling is restricted, thus hindering their applicability. Specifically, these notations focus on capturing tasks and control-flow dependencies, neglecting equally important ingredients of business processes such as data and resources. This research fills this gap by proposing a configurable process modelling notation incorporating features for capturing resources, data and physical objects involved in the performance of tasks. The proposal has been implemented in a toolset that assists analysts during the configuration phase and guarantees the correctness of the resulting process models. The approach has been validated by means of a case study from the film industry.

“Queer” … does not have a uniform : articulations of queer identity in Australian queer student activist media

This article explores articulations of queer identity in recent Australian queer student media. Print media is of particular importance to queer communities because, as Cover argues, it provides a crucial grounding for community development and a model of queer to guide the positioning of identity and activism. This article uses discourse analysis of queer student activists’ media representations of diversity and inclusiveness to investigate the articulations of queer identity in one specific context: metropolitan Australian universities. This reveals real-life appropriations of this contentious term and contributes to a genealogy of sexuality, documenting one visible moment in history.

My "middle way" media studies

I would argue that the problems that contemporary capitalism gives rise to are not the result of the classic exercise of power and hegemony characteristic of the monopoly phase of capitalism but of the “creative destruction” of such a phase. Schumpeter’s famous phrase is reflective of Lash and Urry’s (1987) notion of “disorganised capitalism” or of Robert Reich’s (2007) claim that large corporations have significantly less power now than three decades ago. The consequence is that there is a need to explore an economic “middle way” in debates about the narrative of the relationship between culture and economy, between the Scylla of total explanatory political economy and the Charybdis of tedium-by-case-study. This involves a Schumpeterian emphasis on entrepreneurial or enterprise economics (Cunningham, Banks, and Potts 2008). Schumpeter, in 1962, in Capitalism, Socialism and Democracy, argued that Marx had “no adequate theory of enterprise” and failed to “distinguish the entrepreneur from the capitalist” (quoted in McCraw 2007: 349). Schumpeter, his most recent biographer, Thomas McCraw, “told of capitalism in the way most people experience it: as consumer desires aroused by endless advertising; as forcible jolts up and down the social pecking order; as goals reached, shattered, altered, then reached once more as people try, try again.” He knew that “creative destruction fosters economic growth but also that it undercuts cherished human values” (p. 6). Schumpeter’s most recent biographer, Thomas McCraw, says that he elucidated what capitalism “really feels like” (as quoted in McCraw 2007: 349, 6).

Identity and disciplinarity : Multi-disciplinary student cohorts in Higher Education [Abstract]

This paper will describe a research project that examines the implications of multidisciplinary student cohorts on teaching and learning within undergraduate and postgraduate units in higher education. Whist students generally specialise in one discipline, it is also common that, at some point during their degree, they will choose to undertake subjects that are outside their specialist area. Students may choose a multidisciplinary learning experience either out of interest or because the subject is seen as complementary to their core discipline. When the lens of identity is applied to the multi-disciplinary cohorts in undergraduate and postgraduate units, it assists in identifying learning needs. The nature of disciplinarity, and the impact it has on students’ academic identity, presents challenges to both students and teachers when they engage in teaching and learning, impacting on curriculum design, assessment practices and teaching delivery strategies (Winberg, 2008). This project aims to identify the barriers that exist to effective teaching and learning in units that have multidisciplinary student cohorts. It will identify the particular needs of students in multidisciplinary student cohorts and determine a teaching and learning model that meets the needs of such cohorts.

The media and communications in Australia (3rd ed.)

Traditional media are under assault from digital technologies. Online advertising is eroding the financial basis of newspapers and television, demarcations between different forms of media are fading, and audiences are fragmenting. We can podcast our favourite radio show, data accompanies television programs, and we catch up with newspaper stories on our laptops. Yet mainstream media remain enormously powerful. The Media and Communications in Australia offers a systematic introduction to this dynamic field. Fully updated and revised to take account of recent developments, this third edition outlines the key media industries and explains how communications technologies are impacting on them. It provides a thorough overview of the main approaches taken in studying the media, and includes new chapters on social media, gaming, telecommunications, sport and cultural diversity. With contributions from some of Australia's best researchers and teachers in the field, The Media and Communications in Australia is the most comprehensive and reliable introduction to media and communications available. It is an ideal student text, and a reference for teachers of media and anyone interested in this influential industry.

Digital media literacy : connecting young people’s identities, creative production and learning about video games

This chapter outlines examples of classroom activities that aim to make connections between young people’s everyday experiences with video games and the formal high school curriculum. These classroom activities were developed within the emerging field of digital media literacy. Digital media literacy combines elements of ‘traditional’ approaches to media education with elements of technology and information education (Buckingham, 2007; Warschauer, 2006). It is an educational field that has gained significant attention in recent years. For example, digital media literacy has become a significant objective for media policy makers in response to the increased social and cultural roles of new media technologies and controversies associated with young people’s largely unregulated online participation. Media regulators, educational institutions and independent organizations1 in the United States, Canada, the United Kingdom and Australia have developed digital media literacy initiatives that aim to provide advice to parents, teachers and young people.

Multi-level order, friction and contradiction : the evolution of Australian film industry policy

Cultural policy studies have previously highlighted the importance of multiple logics, friction and contradiction in cultural policy. Recent developments in institutional theory provide a framework for analysing change in cultural policy which explores movement between these multiple and sometimes contradictory logics. This paper analyses the role of friction in the evolution of Australian film industry policy and in particular the tension between competing logics regarding nationalism, commercialism and the state. The paper is suggestive of the relevance of institutional theory as a framework for understanding cultural policy evolution.

Dynamics of multi-articular coordination in neurobiological systems

Although previous work in nonlinear dynamics on neurobiological coordination and control has provided valuable insights from studies of single joint movements in humans, researchers have shown increasing interest in coordination of multi-articular actions. Multi-articular movement models have provided valuable insights on neurobiological systems conceptualised as degenerate, adaptive complex systems satisfying the constraints of dynamic environments. In this paper, we overview empirical evidence illustrating the dynamics of adaptive movement behavior in a range of multi-articular actions including kicking, throwing, hitting and balancing. We model the emergence of creativity and the diversity of neurobiological action in the meta-stable region of self organising criticality. We examine the influence on multi-articular actions of decaying and emerging constraints in the context of skill acquisition. We demonstrate how, in this context, transitions between preferred movement patterns exemplify the search for and adaptation of attractor states within the perceptual motor workspace as a function of practice. We conclude by showing how empirical analyses of neurobiological coordination and control have been used to establish a nonlinear pedagogical framework for enhancing acquisition of multi-articular actions.

Digital storytelling, podcasts, blogs and vlogs : exploring a range of new media texts and forms in English

Curriculum initiatives in Australia emphasise the use of technologies and new media in classrooms. Some English teachers might fear this deployment of technologies because we are not all ‘digital natives’ like our students. If we embrace new media forms such as podcasts, blogs, vodcasts, and digital stories, a whole new world of possibilities open up for literary response and recreative texts, with new audiences and publication spaces. This article encourages English teachers to embrace these new digital forms and how shows we can go about it.
