title: The first description of an archaeal hemicellulase: the xylanase from Thermococcus zilligii strain AN1

authors: Uhl, Andreas M.

subjects: xylanase

abstract: A xylanase has been found in the archaeon Thermococcus zilligii strain AN1 (DSM 2770), which grows optimally at 75°C. The enzyme had a molecular mass of 95 kDa and a unique N-terminal sequence. It had activity against all five xylans tested and against xylose oligomers, but not against other carbohydrate polymers. The K m values found for xylans were typical of those found for bacterial xylanases. The pH optimum for activity was pH 6, and the enzyme half-life at 100°C was 8 min. This is the first description of any archaeal hemicellulase.

title: Architects as nowcasters of housing construction

authors: Holmes, Mark J.

subjects: nowcasting

abstract: For more than four decades, the New Zealand Institute of Economic Research (NZIER) has conducted a two-question, quarterly survey of architect forecasts of public and private sector construction expenditure. This qualitative survey is published one week after the end of each quarter and nine weeks ahead of the official quantitative data thereby giving architect opinion nowcasting status. This paper covers selected aspects of this unexplored series with particular reference to residential housing construction and the value-added information from architects as nowcasters. Specifically, we consider several qualitative-to-quantitative conversion methods, in-sample and out-of-sample performance, cyclical features and respondent dynamics. Although our work relates to architects - a sub-sector of the service industry - our results have a wider application to business survey questions using ordered qualitative responses.

title: Mokopuna rising: Developing a best practice for early intervention in whanau violence

authors: Cooper, Erana

subjects: Maori

abstract: In a very difficult meeting, an extremely unpleasant man was concerned about the possible loss of his power and the continuation of his plans and dreams for the future. And I said, yeah well, you should be worried, because according to your philosophy, when you’re dead, you’re dead. But when I’m dead, my mokopuna will be rising. (Personal Communication, Rob Cooper, 2007) 
“Mokopuna Rising” is about claiming space for Maori to define best practice for reducing and avoiding whanau violence1 It is research in progress towards a PhD, being carried out with the Ngati Hine Health Trust, in Te Taitokerau (Northland).
