On the use of fuzzy inference techniques in assessment models : part II : industrial applications

In this paper, we study the applicability of the monotone output property and the output resolution property in fuzzy assessment models to two industrial Failure Mode and Effect Analysis (FMEA) problems. First, the effectiveness of the monotone output property in a single-input fuzzy assessment model is demonstrated with a proposed fuzzy occurrence model. Then, the usefulness of the two properties to a multi-input fuzzy assessment model, i.e., the Bowles fuzzy Risk Priority Number (RPN) model, is assessed. The experimental results indicate that both the fuzzy occurrence model and Bowles fuzzy RPN model are able to fulfill the monotone output property, with the derived conditions (in Part I) satisfied. In addition, the proposed rule refinement technique is able to improve the output resolution property of the Bowles fuzzy RPN model.

Constructed wetland for treating aquaculture and industrial effluent

This project was a practical assessment of the giant reed Arundo donax in comparison with the common reed, Phragmites autralis, in gravel substrate-based horizontal subsurface flow constructed wetlands designed to treat agro-industrial effluent. Results indicated, the planted CWs were more effective at removing nutrients than the unplanted conrol CWs with A.donax produce larger amounts of biomass than P. australis planted CWs.

The Australian Broadcasting Corporation’s multiplatform projects : industrial logics of children’s content provision in the digital television era

This paper traces the development of children’s multiplatform commissioning at the Australian Broadcasting Corporation (ABC) in the context of the digitalisation of Australian television. Whilst recent scholarship has focussed on ‘post-broadcast’ or ‘second-shift’ industrial practices, designed to engage view(s)ers with proprietary media brands, less attention has been focussed on children’s and young adults’ television in a public service context. Further, although multiplatform projects in the United States and Britain have been the subject of considerable analysis, less work has attempted to contextualise cultural production in smaller media markets. The paper explores two recent multiplatform projects through textual analysis, empirical research (consisting of interviews with key industry personnel) and an investigation of recent policy documents. The authors argue that the ABC’s mixed diet of children’s programming, featuring an educative or social developmental agenda, is complemented by its appeals to audience ‘participation’, with the Corporation maintaining public service values alongside the need to expand audience reach and the legitimacy of its brand. It finds that the ABC’s historical platform infrastructure, across radio, television and online, have allowed it to move beyond a market failure model to exploit multiplatform synergies competitively in the distribution of Australian children’s content to audiences on-demand.

The implied convenience yield of precious metals: safe haven versus industrial usage

During a financial crisis, investors find it convenient to hold gold (Gd) as a safe haven. But during good economic times, manufacturing firms find it convenient to stockpile platinum (Pl), palladium (Pd) and especially silver (Si), for industrial usages. We have three related objectives. First, we examine the nature of cross-market interactions among the convenience yields (cy_it) of {Gd, Pl, Pd, Si}, which are implied from cost-of-carry relations. Second, we test if the more influential cy_it of certain precious metals are also affecting the return, volatility and/or volume dynamics of other precious metals. Third, we analyze if the cy_it of gold is enhanced (diluted) during (after) the Asian and Global financial crises. We find, consistent with our propositions, that during crisis period, gold’s cy_it provides incremental information to the volatility series of {Gd, Pl, Pd, Si}. But during good economic times, it is silver’s cy_it that has the most influence on the return series across {Gd, Pl, Pd, Si}. This is not surprising given that Si has the largest proportion of industrial usage among the four metals.

A cluster randomised trial of an internet-based intervention program for tinnitus distress in an industrial setting

The effectiveness of a therapist-supported Internet intervention program for tinnitus distress in an industrial setting was evaluated using a cluster randomised design. Fifty-six Australian employees of two industrial organisations were randomly assigned, based on their work site (18 work sites from BP Australia and five from BHP Billiton), to either a cognitive behavioural therapy (CBT) program or an information-only control program. Participants were assessed at pre- and postprogram, measuring tinnitus distress, depression, anxiety, stress, quality of life, and occupational health. The CBT program was not found to be superior to the information program for treating tinnitus distress. A high attrition rate and small sample size limit the generalisability of the findings, and further developments of the program and assessment process are needed to enhance engagement and compliance.

Education and training deficits in industrial clusters : empirical evidence that managers can use to rectify the skills gap in Auckland precinct

Tertiary institutions should seek continuous feedback from industries to keep track of the needs of businesses to provide education and training. In designing programmes and upgrading curricula, there are important factors to bear in mind so that programmes "cater" for all levels of learners. The Auckland City Council financed this study, focussing on Auckland's Rosebank Business Precinct (ARBP). Surrounding communities, particularly Maori, Pacific peoples and recent migrants, experience disparities in employment. The target population were 500+ businesses operating on Rosebank Road. A total of 529 businesses were identified. Interviews with 102 companies with a 36-question questionnaire were conducted. Areas were identified and covered in this paper in the ARBP for developing programmes and curricula for tertiary institutions to provide employable students with the right knowledge, skills and attributes to grow and manage existing ventures. In the analysis we point out what education or training is necessary for ARBP to provide greater efficiencies and improvement in profit levels. Recommendations and conclusions are provided.

Bryophytes of urban industrial streetscapes in Victoria, Australia

The bryophyte floristics of industrial/commercial streetscapes of urban Victoria and the importance of various substrata to species richness were explored. Species richness was low compared to healthy natural environments. Thirty mosses from 14 families, and six liverworts, each from different families, were identified. Most species occurred at fewer than 30% of sites, showing the patchy nature of their distribution. Only three species occurred at more than half the sites. Markedly higher species richness occurred on soil than on any other substratum. Epiphytes were extremely few. The low bryodiversity of streetscapes, the patchy nature of the bryophytes and the high number of colonists suggest that the streetscapes have not fulfilled their potential in providing connectivity between urban and non-urban areas. Colonists characteristically occur early in the successional sequence of disturbed areas but, as streetscapes are continually disturbed, colonists effectively are climax species for this habitat. Better management of streetscapes to provide more complex habitat is needed to enable colonisation of these areas by bryophyte species that are more representative of our ever-shrinking natural habitats.

The evolution of freedom of association in Australia's federal industrial relations law: from trade union security to workplace rights

The early provisions protecting freedom of association in Australian federal industrial relations law supported trade union security. The interests of individuals were seen as adequately protected by collective groups. This principle dominated the industrial relations laws from 1904 to the mid-1970s. However, from the late 1970s, the laws were incrementally altered to promote freedom of choice and the rights of individuals not to be part of trade unions. The reframing of the laws also reflected changes in the wider Australian community, manifested particularly in the decline of union density rates. These changes were also part of an international trend, favouring the ideology of neoliberalism which contributed to an unsympathetic environment for trade unions. The current Fair Work Act 2009 (Cth) has signalled a return to collectivism, although freedom of choice is at the heart of the laws rather than the promotion of collective groups. In the absence of legislative support promoting the viability of collective groups, this freedom to choose is threatened, leaving many workers with little choice but to disassociate.
