Searching for a feminist voice : film festivals and negotiating the tension between expectation and intent

International Film Festivals play a vital role in shaping filmmakers’ careers. This paper presents some initial findings from a current major research project, highlighting the significance of particular festival programming of emerging female directors from developing nations. Some filmmakers showcased at festivals actively privilege the voices of women in their films as a means of commenting on pressing cultural and political issues. Ironically, other filmmakers do not subscribe to the label of “feminist” or “woman filmmaker”, even if their respective films represent a strongly coded woman’s point of view. Tensions also arise inevitably when scrutinising women filmmakers from developing nations within a first world film festival context. The expectations of the researcher, the festival, film critics and audiences inevitably must negotiate with the original intentions of the filmmaker. This paper explores the significance of women filmmakers in attendance at the Brisbane International Film Festival (2009) and the International Film Festival Rotterdam (2010).

Haunted by the past : effects of poor management on employee attitudes and turnover

Change management research has largely ignored the effects of organizational change management history in shaping employee attitudes and behavior. This article develops and tests a model of the effects of poor change management history (PCMH) on employee attitudes (trust, job satisfaction, turnover intentions, change cynicism, and openness to change) and actual turnover. We found that PCMH, through PCMH beliefs, led to lower trust, job satisfaction and openness to change, and higher cynicism and turnover intentions. Also, PCMH beliefs predicted employee turnover over 2 years.

Combating computer crime : an international perspective

Given the serious nature of computer crime, and its global nature and implications, it is clear that there is a crucial need for a common understanding of such criminal activity internationally in order to deal with it effectively. Research into the extent to which legislation, international initiatives, and policy and procedures to combat and investigate computer crime are consistent globally is therefore of enormous importance. The challenge is to study, analyse, and compare the policies and practices of combating computer crime under different jurisdictions in order to identify the extent to which they are consistent with each other and with international guidelines; and the extent of their successes and limitations. The purpose ultimately is to identify areas where improvements are needed and what those improvements should be. This thesis examines approaches used for combating computer crime, including money laundering, in Australia, the UAE, the UK and the USA, four countries which represent a spectrum of economic development and culture. It does so in the context of the guidelines of international organizations such as the Council of Europe (CoE) and the Financial Action Task Force (FATF). In the case of the UAE, we examine also the cultural influences which differentiate it from the other three countries and which has necessarily been a factor in shaping its approaches for countering money laundering in particular. The thesis concludes that because of the transnational nature of computer crime there is a need internationally for further harmonisation of approaches for combating computer crime. The specific contributions of the thesis are as follows: „h Developing a new unified comprehensive taxonomy of computer crime based upon the dual characteristics of the role of the computer and the contextual nature of the crime „h Revealing differences in computer crime legislation in Australia, the UAE, the UK and the USA, and how they correspond to the CoE Convention on Cybercrime and identifying a new framework to develop harmonised computer crime or cybercrime legislation globally „h Identifying some important issues that continue to create problems for law enforcement agencies such as insufficient resources, coping internationally with computer crime legislation that differs between countries, having comprehensive documented procedures and guidelines for combating computer crime, and reporting and recording of computer crime offences as distinct from other forms of crime „h Completing the most comprehensive study currently available regarding the extent of money laundered in four such developed or fast developing countries „h Identifying that the UK and the USA are the most advanced with regard to anti-money laundering and combating the financing of terrorism (AML/CFT) systems among the four countries based on compliance with the FATF recommendations. In addition, the thesis has identified that local factors have affected how the UAE has implemented its financial and AML/CFT systems and reveals that such local and cultural factors should be taken into account when implementing or evaluating any country¡¦s AML/CFT system.

Digital signal processing

Signal Processing (SP) is a subject of central importance in engineering and the applied sciences. Signals are information-bearing functions, and SP deals with the analysis and processing of signals (by dedicated systems) to extract or modify information. Signal processing is necessary because signals normally contain information that is not readily usable or understandable, or which might be disturbed by unwanted sources such as noise. Although many signals are non-electrical, it is common to convert them into electrical signals for processing. Most natural signals (such as acoustic and biomedical signals) are continuous functions of time, with these signals being referred to as analog signals. Prior to the onset of digital computers, Analog Signal Processing (ASP) and analog systems were the only tool to deal with analog signals. Although ASP and analog systems are still widely used, Digital Signal Processing (DSP) and digital systems are attracting more attention, due in large part to the significant advantages of digital systems over the analog counterparts. These advantages include superiority in performance,s peed, reliability, efficiency of storage, size and cost. In addition, DSP can solve problems that cannot be solved using ASP, like the spectral analysis of multicomonent signals, adaptive filtering, and operations at very low frequencies. Following the recent developments in engineering which occurred in the 1980's and 1990's, DSP became one of the world's fastest growing industries. Since that time DSP has not only impacted on traditional areas of electrical engineering, but has had far reaching effects on other domains that deal with information such as economics, meteorology, seismology, bioengineering, oceanology, communications, astronomy, radar engineering, control engineering and various other applications. This book is based on the Lecture Notes of Associate Professor Zahir M. Hussain at RMIT University (Melbourne, 2001-2009), the research of Dr. Amin Z. Sadik (at QUT & RMIT, 2005-2008), and the Note of Professor Peter O'Shea at Queensland University of Technology. Part I of the book addresses the representation of analog and digital signals and systems in the time domain and in the frequency domain. The core topics covered are convolution, transforms (Fourier, Laplace, Z. Discrete-time Fourier, and Discrete Fourier), filters, and random signal analysis. There is also a treatment of some important applications of DSP, including signal detection in noise, radar range estimation, banking and financial applications, and audio effects production. Design and implementation of digital systems (such as integrators, differentiators, resonators and oscillators are also considered, along with the design of conventional digital filters. Part I is suitable for an elementary course in DSP. Part II (which is suitable for an advanced signal processing course), considers selected signal processing systems and techniques. Core topics covered are the Hilbert transformer, binary signal transmission, phase-locked loops, sigma-delta modulation, noise shaping, quantization, adaptive filters, and non-stationary signal analysis. Part III presents some selected advanced DSP topics. We hope that this book will contribute to the advancement of engineering education and that it will serve as a general reference book on digital signal processing.

The role of academic community in higher learning : Alternatives to a drive-thru education

The purpose of our paper is to illustrate the fundamental importance of developing academic community among first year students. We argue that a sense of academic community is of fundamental importance in combating the effects of the neo-liberal economic discourse on higher education, and that the values of higher education are incongruent with those of economic rationalism. The discursive commodification of the student, and of education itself, works against the formation of community, both within the university environment and in the wider society. We argue that, at present, the dominant discourse shaping the social practice of higher education is that of neo-liberal economics. Community values stand in opposition to the dominant discourse, and are integral to the long-term survival of a socially critical and socially responsive society. We conclude that the importance of establishing a sense of academic community during the first year of university is justified by its ultimate value to society.

A systematic approach to evaluate the process improvement in lean manufacturing organizations

Numerous tools and techniques have been developed to eliminate or reduce waste and carry out Lean concepts in the manufacturing environment. However, in practice, manufacturers encounter difficulties to clearly identify the weaknesses of the existing processes in order to address them by implementing Lean tools. Moreover, selection and implementation of appropriate Lean strategies to address the problems identified is a challenging task. According best of authors‟ knowledge, there is no method available to quantitatively evaluate the cost and benefits of implementing a Lean strategy to address the weaknesses in the manufacturing process. Therefore, benefits of Lean approaches cannot be clearly established. The authors developed a methodology to quantitatively measure the performances of a manufacturing system in detecting the causes of inefficiencies and to select appropriate Lean strategies to address the problems identified. The proposed methodology demonstrates that the Lean strategies should be implemented based on the contexts of the organization and identified problem in order to achieve maximum cost benefits. Finally, a case study has been presented to demonstrate how the procedure developed works in practical situation.

A method for evaluating lean assembly process at design stage

Lean product design has the potential to reduce the overall product development time and cost and can improve the quality of a product. However, it has been found that no or little work has been carried out to provide an integrated framework of "lean design" and to quantitatively evaluate the effectiveness of lean practices/principles in product development process. This research proposed an integrated framework for lean design process and developed a dynamic decision making tool based on Methods Time Measurement (MTM) approach for assessing the impact of lean design on the assembly process. The proposed integrated lean framework demonstrates the lean processes to be followed in the product design and assembly process in order to achieve overall leanness. The decision tool consists of a central database, the lean design guidelines, and MTM analysis. Microsoft Access and C# are utilized to develop the user interface to use the MTM analysis as decision making tool. MTM based dynamic tool is capable of estimating the assembly time, costs of parts and labour of various alternatives of a design and hence is able to achieve optimum design. A case study is conducted to test and validate the functionality of the MTM Analysis as well as to verify the lean guidelines proposed for product development.

Work integrated learning for life : encouraging agentic engagement

In a rapidly changing world where new work patterns impact on our health, relationships and social fabric, it is critical that we reconsider the role universities could or should play in helping students prepare for the complexities of the 21st century. Efforts to respond to economic imperatives such as the skills shortage have seen a rush to embed work integrated and career development learning in the curriculum as well as a strengthening of the discourse that the university’s role is primarily to produce industry ready or ‘oven ready and self basting’ graduates (Atkins, 1999). This narrow focus on ‘giving industry what industry wants’ (Patrick, Peach & Pocknee, 2009) ignores the importance of helping students develop the types of skills and dispositions they will need. To enable students to thrive not just survive socially and economically in a radically unknowable world, where knowledge becomes obsolete, we need to be ready to develop new futures (Barnett, 2004). This paper considers the concept of ‘work’, the role it plays in our lives, and our aspirations to build sustainable, socially connected communities. We revisit the assumptions underlying the employability argument (Atkins, 1999) in the light of changing notions of work (Hagel, Seely Brown & Davison, 2010), and the need for higher education to contribute to a better and more sustainable society (Pocock, 2003). Specifically we present initiatives developed from work integrated learning (WIL) programs in the United Kingdom and Australia, where WIL programs are framed within the broader context of real world and life-wide curriculum (Jackson, 2010), and where transferable skills and elements of work-related learning programs prepare students for less certain job futures. Such approaches encourage students to take an agentic role (Billett & Pavlova, 2005) in selecting their work possibilities to develop resilience and capabilities to deal with new and challenging situations, assisting students to become who they want to be not just what they want to be. The theoretical and operational implications and challenges of shaping real world and life-wide curriculum will be investigated in more depth in the next phase of this research.

Middle school students' perceptions of engineering

This paper focuses on implementing engineering education in middle school classrooms (grade levels 7-9). One of the aims of the study was to foster students’ and teachers’ knowledge and understanding of engineering in society. Given the increasing importance of engineering in shaping our daily lives, it is imperative that we foster in students an interest and drive to participate in engineering education, increase their awareness of engineering as a career path, and inform them of the links between engineering and the enabling subjects, mathematics, science, and technology. Data for the study are drawn from five classes across three schools. Grade 7 students’ responded to initial whole class discussions on what is an engineer, what is engineering, what characteristics engineers require, engineers (family/friends) that they know, and subjects that may facilitate an engineering career. Students generally viewed engineers as creative, future-oriented, and artistic problem finders and solvers; planners and designers; “seekers” and inventors; and builders of constructions. Students also viewed engineers as adventurous, decisive, community-minded, reliable, and “smart.” In addition to a range of mathematics and science topics, students identified business studies, ICT, graphics, art, and history as facilitating careers in engineering. Although students displayed a broadened awareness of engineering than the existing research suggests, there was limited knowledge of various engineering fields and a strong perception of engineering as large construction.

The desire for the construction industry to move towards lifecycle carbon emissions analysis

A significant reduction in carbon emissions is a global mission and the construction industry has an indispensable role to play as a major carbon dioxide (CO2) generator. Over the years, various building environmental assessment (BEA) models and concepts have been developed to promote environmentally responsible design and construction. However, limited attention has been placed on assessing and benchmarking the carbon emitted throughout the lifecycle of building facilities. This situation could undermine the construction industry’s potential to reduce its dependence on raw materials, recognise the negative impacts of producing new materials, and intensify the recycle and reuse process. In this paper, current BEA approaches adopted by the construction industry are first introduced. The focus of these models and concepts is then examined. Following a brief review of lifecycle analysis, the boundary in which a lifecycle carbon emission analysis should be set for a construction project is identified. The paper concludes by highlighting the potential barriers of applying lifecycle carbon emissions analysis in the construction industry. It is proposed that lifecycle carbon emission analysis can be integrated with existing BEA models to provide a more comprehensive and accurate evaluation on the cradle-to-grave environmental performance of a construction facility. In doing so, this can assist owners and clients to identify the optimum solution to maximise emissions reduction opportunities.

Development of the sustainable building and construction products industry in Australia

This paper draws on a major study the authors conducted for the Australian Government in 2009. It focuses on the diffusion issues surrounding the uptake of sustainable building and construction products in Australia. Innovative sustainable products can minimise the environmental impact during construction, while maximising asset performance, durability and re-use. However, there are significant challenges faced by designers and clients in the selection of appropriate sustainable products in consideration of the integrated design solution, including overall energy efficiency, water conservation, maintenance and durability, low-impact use and consumption. The paper is a review of the current state of sustainable energy and material product innovations in Australia. It examines the system dynamics surrounding these innovations as well as the drivers and obstacles to their diffusion throughout the Australian construction industry. The case product types reviewed comprise: solar energy technology, small wind turbines, advanced concrete technology, and warm-mixed asphalt. The conclusions highlight the important role played by Australian governments in facilitating improved adoption rates. This applies to governments in their various roles, but particularly as clients/owners, regulators, and investors in education, training, research and development. In their role as clients/owners, the paper suggests that government can better facilitate innovation within the construction industry by adjusting specification policies to encourage the uptake of sustainable products. In the role as regulators, findings suggest governments should be encouraging the application of innovative finance options and positive end-user incentives to promote sustainable product uptake. Also, further education for project-based firms and the client/end users about the long-term financial and environmental benefits of innovative sustainable products is required. As more of the economy’s resources are diverted away from business-as-usual and into the use of sustainable products, some project-based firms may face short-term financial pain in re-shaping their businesses. Government policy initiatives can encourage firms make the necessary adjustments to improve innovative sustainable product diffusion throughout the industry.

Instantaneous phase of the autocorrelation and robustness to signal-dependent noise

The phase of an analytic signal constructed from the autocorrelation function of a signal contains significant information about the shape of the signal. Using Bedrosian's (1963) theorem for the Hilbert transform it is proved that this phase is robust to multiplicative noise if the signal is baseband and the spectra of the signal and the noise do not overlap. Higher-order spectral features are interpreted in this context and shown to extract nonlinear phase information while retaining robustness. The significance of the result is that prior knowledge of the spectra is not required.

Approaches to acquiring ‘doctorateness’ in the creative industries : an Australian perspective

Over the last two decades, particularly in Australia and the UK, the doctoral landscape has changed considerably with increasingly hybridised approaches to methodologies and research strategies as well as greater choice of examinable outputs. This paper provides an overview of doctoral practices that are emerging in the context of the creative industries, with a focus on practice-led approaches within the Doctor of Philosophy and recent developments in professional doctorates, from a predominantly Australian perspective. In interrogating what constitutes ‘doctorateness’ in this context, the paper examines some of the diverse theoretical principles which foreground the practitioner/researcher, methodological approaches that incorporate tacit knowledge and reflective practice together with qualitative strategies, blended learning delivery modes, and flexible doctoral outputs; and how these are shaping this shifting environment. The paper concludes with a study of the Doctor of Creative Industries at Queensland University of Technology as one model of an interdisciplinary professional research doctorate.

Different inflections

Australia has often been defined by its landscape – actual, romanticized, imagined – iconic images and experiences taken up by artists in a myriad of ways. This paper examines inter/intra cultural practices of three Australian dance companies and their directors, and how they inflect images of Australia in different ways. Each artist brings perspectives from their particular hybridized cultural and ethnic backgrounds as well as their formative dance experiences. In their practices, notions of landscape embrace physical, metaphorical and spiritual dimensions. Kai Tai Chan, who founded the One Extra Company in 1976, pioneered accessible and confronting intercultural dance theatre in Australia from the 1970s to the 1990s, challenging our notions of what it is to be Australian. A Chinese Malay who came to Australia to study architecture, he stayed to create a significant body of work in which different cultural frameworks became lenses through which to explore stories of ordinary lives and experiences, revealing complexities of the human condition and larger social-political issues. Spiritual connections feature strongly in the practice of another Chinese Malay Australian, Tony Yap. Here the landscape is an inner one influenced by a form of Malaysian trance dance known as the sen-siao (“spirit cloud”) tradition. Yap has forged a unique space in the Australian dance and theatre scene, exploring a movement language informed by psycho-physical research, Asian shamanistic trance dance, Butoh, voice and visual design. Whilst primarily a solo performer, his practice includes collaborations with Asian diasporic as well as Anglo Australian cross-cultural visual and sound artists. His work is situated in a metaphysical rather than socio political context. In contrast, the newest company to emerge on the intercultural Australian stage is Polytoxic, reflecting a Pacific rather than Asian inflection. Key members, Fa’alafi and Efeso Fa’anana (both of Samoan descent) and Leah Shelton (of Anglo-Saxon descent), aim to critique the exoticism and cultural kitsch that often accompanies representations of the Pacific islands, with a pastiche of street dance, cabaret and contemporary techniques, blended with traditional Polynesian vocabulary. A parallel aim is to provide audiences with insights into the traditions and history of Samoa from the perspective of the artists as contemporary Australians. This examination, spanning three decades of inter/intra cultural practices, reveals stylistic, generational and philosophical differences with a commonality of variously inflected notions of landscape, spirituality and identity.

Awakening the spirit : telling the stories

Stephen Page talking with Cheryl Stock Stephen Page is one of the most significant dance artists working in Australia today, unique in his ability to forge and sustain a company of Indigenous artists through his seminal leadership of Bangarra Dance Theatre, which celebrated its 20 year anniversary in 2009. Together with the many artists who have contributed to the Bangarra vision, Stephen has created a distinctive contemporary Indigenous dance style and approach, celebrated for the stories it tells of the Aboriginal and Torres Strait Islander experience. Fusing the traditional with the contemporary through a connection to the spirit of the land and its people, Stephen has inspired and influenced a generation of Aboriginal and Torres Strait Islander dance and theatre artists as a choreographer, director and mentor. His down to earth humour, his passion and his sensitivity draw us as audience, Indigenous and non-Indigenous alike, to his theatrical stories of place and spirit – both ancient and modern – in ways that simultaneously transcend and reaffirm the particular cultural experience which informs them. This conversation covers the early years of growing up with his 'urban clan', discovering dance and politics and his spiritual awakening at Yirrkala. Stephen then describes moving in and out of different realities as a member of Sydney Dance Company whilst simultaneously exploring his Indigenous dance voice, the transition from dancer to choreographer, creating the Bangarra identity and the intercultural experiment of 'Rites' with the Australian Ballet. The last section looks at his various roles as an artistic director and nurturing the next generation of Indigenous artists.
