Building an effective trade practices commission : the role of Professor Robert Baxt AO

Bob Baxt, the third Chairman of the Trade Practices Commission, served for a single three year term from 1988 to 1991. He followed Bob McComas, who had deliberately adopted a non-litigious approach to preserving the competitive process, believing that he understood business as an insider and that much of what it did was not anti-competitive, when correctly viewed. Baxt was far more pro-active in his approach, and more closely aligned with that of the first Chairman, Ron Bannerman. Baxt sought to push the frontiers of investigation and precedent, and perhaps, more significantly, sought to influence his Ministers, the government, public servants and public opinion about the need to expand the coverage of the Trade Practices Act, increase penalties and properly resource the Commission so that it could perform its assigned roles. This article examines Baxt’s early and on-going role in teaching Australian students and professionals through his interdisciplinary Trade Practices Workshops, the political context of Baxt’s tenure, including his relations with the Attorney-General ,Michael Duffy, and his skilful handling of the Queensland Wire case.

The well-being of older job-seekers : implications for the labour force participation agenda

Throughout the developed world demographic trends and their forecast consequences are attracting the attention of governments, academics, think tanks and the popular press alike. Population aging, in particular, is the focus of many and has generated extensive debate. Approaches commonly advocated in the literature include a mix of ‘population', ‘participation’ and ‘productivity’ measures. Immigration and population policy alongside industry reform and related productivity initiatives are also being pursued. Participation, however, remains a key element of the demographic change policy response. Evidence suggests however, that these approaches are unlikely to deliver the necessary labour force volumes. This has prompted a shift in the participation agenda to also include a stronger focus on skilled and experienced older workers. The literature suggests, however, that the current suite of practices are less than effective for the long-term unemployed, previously long-tenured older workers with specialised skills and trade-displaced workers. Adverse health and human capital outcomes often associated with social disadvantage are complicating factors. This reminds of the complexity of the challenge in seeking to deliver social equity to the disadvantaged and suggests a need for an alternative policy architecture. By integrating the three concepts of health capital, human capital and social capital we show how policy has to change if the older age cohorts of jobseekers are to be assisted to remain employable. This review includes an examination of current policy, a consolidation of the literature and original data.

Cross voltage control with inner hysteresis current control for multi-output boost converter

Multi-output boost (MOB) converter is a novel DC-DC converter unlike the regular boost converter, has the ability to share its total output voltage and to have different series output voltage from a given duty cycle for low and high power applications. In this paper, discrete voltage control with inner hysteresis current control loop has been proposed to keep the simplicity of the control law for the double-output MOB converter, which can be implemented by a combination of analogue and logical ICs or simple microcontroller to constrain the output voltages of MOB converter at their reference voltages against variation in load or input voltage. The salient features of the proposed control strategy are simplicity of implementation and ease to extend to multiple outputs in the MOB converter. Simulation and experimental results are presented to show the validity of control strategy.

Using a current source to improve efficiency of a plasma system

This paper presents the possibility of utilizing a current source topology instead of a voltage source as an efficient, flexible and reliable power supply for plasma applications. A buck-boost converter with a current controller has been used to transfer energy from an inductor to a plasma system. A control strategy has also been designed to satisfy all the desired purposes. The main concept behind this topology is to provide high dv/dt regardless of the switching speed of a power switch and to control the current level to properly transfer adequate energy to various plasma applications.

A new predictive current control technique for multilevel converters

Multilevel inverters provide an attractive solution for power electronics when both reduced harmonic contents and high voltages are required. In this paper, a novel predictive current control technique is proposed for a three-phase multilevel inverter, which controls the capacitors voltages and load currents with low switching losses. The advantage of this contribution is that the technique can be applied to more voltage levels without significantly changing the control circuit. The three-phase three-level inverter with a pure inductive load has been implemented to track reference currents using analogue circuits and programmable logic device.

Small business pedagogic practices

Understanding how learning for small businesses should best proceed constitutes a worthwhile, yet challenging, pedagogic project. In order to maintain their viability, small businesses need to be able to respond to new practices and tasks. Yet small businesses seem neither attracted to nor to value the kinds of taught courses that are the standard pedagogic practice of vocational education systems.

Co-creative labour

This article introduces a special issue on the topic of co-creative labour. The term co-creation is used to describe the phenomenon of consumers increasingly participating in the process of making and circulating media content and experiences. Practices of user-created content and user-led innovation are now significant sources of both economic and cultural value. But how should we understand and analyse these value-generating activities? What are the identities and forms of agency that constitute these emerging co-creative relations? Should we define these activities as a form of labour and what are the implications and impacts of co-creative practices on the employment conditions and professional identities of people working in the creative industries? In answering these questions we argue that careful attention must be paid to how the participants themselves (both professional and non-professional, commercial and non-commercial) negotiate and navigate the meanings and possibilities of these emerging co-creative relationships for mutual benefit. Co-Creative media production is perhaps a disruptive agent of change that sits uncomfortably with our current understandings and theories of work and labour. The articles in this special issue follow and unpack the often diverse and contradictory ways in which the participants themselves use and remake the social categories of work and labour as they seek to co-ordinate and contest co-creative media practices.

The 'authentic dancer' as a tool for audience engagement

An engagement with performance is an experiential event. To have a lived experience within a performance construct infers that the experience is somehow ‘more live’. This paper situates the body of the audience member as a site of understanding and meaning making, and challenges the role of the traditional ‘passive’ presentation format and ensuing ethical considerations within that assertion. It looks at the relationships between audience experience and a series of creative tools that facilitate subtle shifts in this traditional dance paradigm. Along with the tools of audience agency, liminality, variations of site and proximity – tools that create engagement via physical interactions with the audience – can ‘performer authenticity’ also become a tool of connection with the audience? This paper looks at the overarching field of contemporary dance, with a primary focus on Western contemporary dance and the traditional dance paradigms prevalent in the construction and presentation of that form. It outlines the role of the experiential within this form and highlights established research and creation tools that encourage audience connection via audience interaction. It also looks at the role of the dancer within this construct, citing both current qualitative research into audience responses, as well as current theory and creative practice from an international field of artists creating work with the ‘authentic dancer’.

Examining the role of human resource management in continuous improvement

The objective of this paper is to take a first step in developing a theoretical framework describing the role of HRM in successful CI, based on the current literature from both fields. To this end, elements from the CI Maturity Model and a framework depicting the role of HRM in innovation serve as a foundation for examining how specific bundles of HRM practices utilised during different phases of the CI implementation process may contribute to sustained organisational and enhanced operational performance. The primary contribution of this paper is theoretical; however, the framework has practical value in that it suggests important relationships between HRM practices and behaviours necessary for successful CI. A preliminary test of the framework in an empirical setting is summarised at the conclusion of this paper, where a number of possible research avenues are also suggested.

MiLK. Mobile Learning Kit

The Mobile Learning Kit is a new digital learning application that allows students and teachers to compose, publish, discuss and evaluate their own mobile learning games and events. The research field was interaction design in the context of mobile learning. The research methodology was primarily design-based supported by collaboration between participating disciplines of game design, education and information technology. As such, the resulting MiLK application is a synthesis of current pedagogical models and experimental interaction design techniques and technologies. MiLK is a dynamic learning resource for incorporating both formal and informal teaching and learning practices while exploiting mobile phones and contemporary digital social tools in innovative ways. MiLK explicitly addresses other predominant themes in educational scholarship that relate to current education innovation and reform such as personalised learning, life-long learning and new learning spaces. The success of this project is indicated through rigorous trials and actual uptake of MiLK by international participants in Australia, UK, US and South Africa. MiLK was awarded for excellence in the use of emerging technologies for improved learning and teaching as a finalist (top 3) in the Handheld Learning and Innovation Awards in the UK in 2008. MiLK was awarded funding from the Australasian CRC for Interaction Design in 2008 to prepare the MiLK application for development. MiLK has been awarded over $230,000 from ACID since 2006. The resulting application and research materials are now being commercialised by a new company, ‘ACID Services’.

An examination of IS conference reviewing practices

There has been considerable interest over the years within the IS research community into how to shape articles for successful publication. Little effort has been made, however, to examine the reviewing criteria that make a difference to publication. We argue that, to provide better guidance to authors, more solid evidence is needed into the factors that contribute to acceptance decisions. This paper examines empirically the outcomes of the reviewing processes of three well-known IS conferences held in 2007. Our analyses reveal four major findings. First, the evaluation criteria that influence the acceptance/rejection decision vary by conference. Second, those differences can be explained in terms of the maturity and breadth of the specific conference of interest. Third, while objective review criteria influence acceptance/rejection decisions, subjective assessment on the part of the program committees may also play a substantial role. Fourth, while high scores on objective criteria are essential for acceptance, they do not guarantee acceptance. On the other hand, low scores on any criterion are likely to result in rejection.

The relationship between HRM practices and service behaviour in South African service organizations

This paper reports on findings from research conducted in South African service organizations that frontline employees' perceptions of HRM practices have a direct influence on their service behaviour. Specific HRM practices have more impact than others and this was attributed to the influence of external factors such as the socio-political situation and national culture and to internal factors linked to the way managers implemented the HRM practices in the organization. Organizational commitment was found to play a mediating role in the relationship between frontline employees' perceptions of HRM and their service behaviour.

Who's talking? Communication and the casual/part-time nurse : a literature review

The rapidly evolving nursing working environment has seen the increased use of flexible non standard employment, including part-time, casual and itinerate workers. Evidence suggests that the nursing workforce has been at the forefront of the flexibility push which has seen the appearance of a dual workforce and marginalization of part- time and casual workers by their full-time peers and managers. The resulting fragmentation has meant that effective communication management has become difficult. Additionally, it is likely that poor organisational communication exacerbated by the increased use of non standard staff, is a factor underlying current discontent in the nursing industry and may impact on both recruitment and retention problems as well as patient outcomes. This literature review explores the relationship between the increasing casualisation of the nursing workforce and, among other things, the communication practices of nurses within healthcare organisations.
