title: Draft Genome Sequence of Venenivibrio stagnispumantis CP.B2T, Isolated from Champagne Pool, Waiotapu, Aotearoa-New Zealand

authors: Power, Jean Florence

abstract: Venenivibrio stagnispumantis strain CP.B2T is a thermophilic, chemolithoautotrophic bacterium from the family Hydrogenothermaceae (phylum Aquificota), isolated from Champagne Pool in the Waiotapu geothermal field, Aotearoa-New Zealand. The genome consists of 1.73 Mbp in 451 contigs with a 30.8 mol% G+C content.

title: Test of AMS 14C dating of pollen concentrates using tephrochronology

authors: Newnham, Rewi M.

subjects: AMS radiocarbon dating

abstract: Previous attempts to radiocarbon date sediments >10 kyr from the high rainfall region of Westland, New Zealand, a critical location for investigation of interhemispheric patterns of climate change, have been problematic. This study, building on recent work by Vandergoes and Prior (2003), shows that AMS 14C dating of pollen concentrates has potential to provide more reliable ages than other sediment constituents, including plant macrofossils. The method was applied to sediments from three sites containing the 22.6k 14C yr Kawakawa Tephra, which provided an independent test of the 14C ages. Although some minor laboratory contamination was detected in tests on background standards, the modelled relationship between sample mass and measured 14C content permitted an appropriate correction to be determined. Improved pollen concentrations derived by density separation between 1.4 and 1.2 specific gravity and sieving in the range 10-50  m provided either older ages than other fractions of the same sample or, where in situ contamination was not evident, equivalent ages. Differences in degree of in situ contamination between depositional environments indicated that, in Westland, lake sites may be less susceptible to contamination by younger carbon than peat sites, where this process may be facilitated by root penetration into underlying sediments.

title: The anthropologist as tribal advocate

authors: Hopa, Ngapare K

subjects: economic conditions

abstract: My colleague has outlined some of the major issues facing New Zealand and its indigenous Polynesians - the Maaori - who not so long ago were ranked among the most documented in the world and the country as THE laboratory of race relations.
The present disadvantaged and dependent status of Maaori people show how illusory that notion is and, for New Zealand anthropologists, the challenge it presents in helping Maaori to attain socio-economic sovereignty within the 'partnership' promised by the Treaty of Waitangi.
In the late 60s and since, a few 'radical' mostly 'native' anthropologists can be said to have risen to the challenge that Gough (1968) and others, laid down, but it cannot be said, even now, that the profession as a whole in New Zealand, has been responsive.
Perhaps it is still committed to the myth of scientific objectivity, or, after regarding themselves as champions of a powerless and marginal people, has not recovered from the accusation of impotency during the social ferment of the 70s and since. To be fair, there were a few individuals who were allied with the protest movement but whose contributions were not acknowledged. They rode out the storm however and have continued to contribute significantly to the Maaori cause.
