title: Job vacancy monitoring in New Zealand

authors: Silverstone, Brian

subjects: job vacancies

abstract: The now widespread use of the internet as a source of information on job vacancies may have undermined the usefulness of newspaper advertisements - and possibly surveys - as the traditional sources of timely, cost-effective and accurate information on labour market openings. This paper outlines the New Zealand Department of Labour job vacancy series.  This is followed by selected international illustrations, measurement options, job vacancy reporting and an assessment of the Department of Labour’s experience with vacancy monitoring. The overall aims of this paper are to raise the awareness, in principle, of job vacancy data as a useful indicator of labour market conditions and the challenges, in practice, of creating appropriate series.

title: Assessment of the Potential of Waste Copper Chromium and Arsenic (CCA)-Treated Timber Fibre Reinforced Polypropylene Composites for Construction

authors: Nelson, Jacob

abstract: This paper investigates the potential of recycling waste copper chromium and arsenic (CCA)-treated timber for use as a reinforcement material in wood–plastic composites (WPCs) produced for use in construction, including an assessment of mechanical properties and the leaching of heavy metals. Wood flour was obtained through mechanical grinding, and fibres were obtained through alkaline digestion followed by bleaching. Composites produced with 40 wt.% bleached fibres showed increased tensile strength from 18.5 MPa for the polypropylene used as the matrix to 27.6 MPa. Likewise, the Young’s modulus was increased from 0.84 to 2.33 GPa. The treatment of fibres was found to reduce arsenic concentration by up to 99.9%. Furthermore, the arsenic in the leachate from composites was found to decrease from 41.29 to 0.07 ppb when comparing CCA-treated wood flour composites to bleached fibre composites. The composites’ material properties indicate that the use of end-of-life CCA-treated timber could be used to produce a composite material that could be used in New Zealand’s building sector to meet the requirements of semi-structural applications.

title: Maori perspectives of the environment: Summary document

authors: Whangapirita, Laura

subjects: Maori

abstract: The Community and Economy Programme at Environment Waikato has developed a partnership with the Maori and Psychology Research Unit of the University of Waikato to further assist in strengthening its commitment to cultural research and information work. This relationship facilitated the development of the Maori and Environment project, which was conducted in two stages and produced a number of significant research reports throughout 2003. This is the summary document.
