title: Waitangi Soda Springs alum dosing – bioavailability of aluminium 2013

authors: Ling, Nicholas

abstract: Continuous alum dosing of the Waitangi Soda Springs at Lake Rotoehu commenced in 2010 to reduce inflows of dissolved reactive phosphorus to Lake Rotoehu. Analyses of bioaccumulation in the tissues of kōura and goldfish from Lake Rotoehu were undertaken on animals collected in September 2013 to determine the bioavailability and bioaccumulation of aluminium. Comparative analyses were undertaken on kōura and goldfish collected from Lakes Rotorua and Rotoiti. Lake Rotoehu kōura and goldfish showed slightly elevated aluminium concentrations in the gills indicating enhanced exposure to aluminium but little evidence for significant bioaccumulation in tissues.

title: Tracking patterns of tribal identification in the New Zealand census, 1991 to 2006

authors: Kukutai, Tahu

abstract: Despite the growing political and economic importance of iwi in New Zealand, little attention has been given to their changing demography. Using data from the New Zealand Census of Population and Dwellings, we analyse the growth trajectories of four iwi - Ngāi Tahu, Waikato, Ngāti Awa and Tūhoe - between 1991 and 2006. We find a great deal of variation in iwi growth between censuses and over the entire focal period. In most instances, iwi birth cohorts increased rather than decreased in size, and gains from “new” members were especially marked among children, the middle-aged and women. The findings confirm the importance of accounting for non-demographic factors when projecting and planning for future iwi population growth.

title: PBRF on the horizon

authors: Smith, Ron C.

subjects: PBRF

abstract: New Zealand universities spend a great deal of time and money evaluating the research outputs of their staff in the cause of Performance Based Research Funding (PBRF).  This time and money is wasted since the assumptions that lie behind this process are fatally flawed and the results are neither valid nor fair.  Additionally PBRF is inconsistent with the universities’ obligations to be ‘critic and conscience’ for society and to scholarship, itself.  The paper argues that no further assessments of this kind should be undertaken.
