Power and passion:remoulded teamwork in a plastics factory

Purpose: – The purpose of this paper is to document the progress made in a specified period and the experience of managers and staff in sustaining the high performance team approach in a plastics factory.

Design/methodology/approach: – Single-case analysis was conducted on data collected through semi-structured interviews and site observations made with two managers and one team of six in a multinational plastics manufacturer (Visy) headquartered in Australia.

Findings: – Based on the authors' experiences and literature review a successful high performance team requires clear targets and efficiency standards, communication, rules of behaviour, continual input of facts and feedback, and last but not least – recognition of successes.

Research limitations/implications: – The findings are based on observations and interviews conducted in one part of a multinational organization in Australia. No follow-up interviews could be undertaken to track the progress.

Originality/value: – No other similar study had been undertaken in this organisation documenting the experiences of a quality improvement team and its interactions with managers. The findings have practical implications for industrial and other kinds of organisations engaged in implementing quality improvements through enhanced teamwork.

Design and analysis of efficient rectifiers for wireless power harvesting in DBS devices

This paper presents an analysis of optimum rectifier circuits for wireless energy harvesting in deep brain stimulation (DBS) devices. Since DBS demands compact and low power consumption devices, small, high conversion efficient, and high output voltage rectifiers need to be developed. The investigation that is presented in this paper is analytical and simulated based. Analysis on a variety of circuit configurations brings more evidence to improve the performance of rectifiers. Analytical parameters influencing the output DC voltage and the efficiency of the rectifiers are described. The operating frequency of the 915 MHz industrial, scientific and medical (ISM) radio band is used in this study. The maximum conversion efficiency of the LC matched half wave rectifier, the Greinacher voltage doubler, the Delon doubler, and the 2-stage voltage multiplier is obtained as 56.34%, 74.45%, 71.48%, and 31.44%, respectively, at the 30 dBm input power level. The corresponding maximum output DC voltages are 6.27 V, 16.83 V, 13.36 V, and 9.20 V. Thus the Greinacher voltage doubler is deemed as the best configuration according to the conversion efficiency and the output voltage measurements.

Investigating ‘community’ through a history of responses to asbestos-related disease in an Australian industrial region

The government of the State of Victoria has been slow to acknowledge the social costs of asbestos-related diseases (ARD) in the Latrobe Valley. Despite the emphasis on ‘community’ in the discipline of public health and in public health services since the 1970s, ARD was only recognised as a community-wide health problem because of the advocacy of people directly affected by it. An historical view of responses to ARD in a community established as an appendage to the publicly owned power industry and infused with an ethic of public service, shows that contests over the definition of ‘community’ lay at the heart of these responses. It also shows that such disputes did not arise only from the reluctance of authorities to acknowledge the problems resulting from the extensive use of asbestos in power stations. The paper highlights the political nature of the notion of ‘community’ and in doing so raises questions that have implications beyond its narrow regional focus.
