title: MOA: Massive Online Analysis

authors: Bifet, Albert

subjects: computer science

abstract: Massive Online Analysis (MOA) is a software environment for implementing algorithms and running experiments for online learning from evolving data streams. MOA includes a collection of offline and online methods as well as tools for evaluation. In particular, it implements boosting, bagging, and Hoeffding Trees, all with and without Naïve Bayes classifiers at the leaves. MOA supports bi-directional interaction with WEKA, the Waikato Environment for Knowledge Analysis, and is released under the GNU GPL license.

title: The chronology of occupation at Teouma, Vanuatu: Use of a modified chronometric hygiene protocol and Bayesian modeling to evaluate midden remains

authors: Petchey, Fiona

subjects: Teouma

abstract: A number of radiocarbon dates, both published and unpublished have been obtained from archaeological deposits across the Teouma site on the island of Efate in Vanuatu. These are on a range of materials from the midden and associated cemetery including charcoal (13) and shell (7) as well as a number of less commonly dated 14C sample types including bone from 2 terrestrial giant tortoises (?Meiolania damelipi), 8 pigs (Sus scrofa) and 2 chickens (Gallus gallus). Thirty-six human bone collagen dates and 5 Conus sp. shell ring artifacts from the cemetery context have been discussed in detail elsewhere (Petchey et al., 2014). In this paper, we evaluate the radiocarbon data according to observed contextual associations and established understandings of 14C offsets, and collate all available information in a Bayesian framework to establish the age and duration of the settlement at Teouma. This analysis provides a maximum age range for the Lapita deposits of between 3000 and 2560 cal BP and a most likely start date of 2920–2870 cal BP and end date of 2870–2750 cal BP (68.2% prob.). This is slightly younger age for the deposits than previously reported, but is in keeping with evaluation of the burials themselves, the majority of which are dated to between 2940 and 2720 cal BP. This age range indicates that the site was in use at the same time as colonization events in Tonga (2850–2830 cal BP) and Fiji (3020–2860 cal BP), and supports the hypothesis that Vanuatu was at the center of a region-wide interaction sphere for several generations after initial settlement.

title: Riariakina ō rongo hirikapo From kōhanga reo to kura

authors: Hohepa, Margie Kahukura

abstract: Ko te kaupapa tonu, ko te whakatupu i te mahara o te hirikapo kia tiu ai ki te muri, arā, kia puta he whakaaro i pokepokengia nō roto tonu i ngā whakahekenga kāwai o ngā tūpuna o te tamaiti, kua maranga te wā e kaumātua haere ana te tamaiti, ngōna kanohi kua huaki, ngōna taringa kua pīkari, ngā whakaaro kua korikori, tōna wairua hīkaka kua ngawhā, ngērā kaupapa katoa o te tamaiti i taua wā o te tupu. Mā tēnei kōrero hoki hei kawe te taonga o te rongo hirikapo, arā, ngā whakaaro, ngā mahara, nāna ko te waha, nā te waha ko te kupu kōrero e makere iho ai i te ārero tarapepe. Heoi anō he tohutohu anō kei roto e kī ana, manaakingia ngā kai o te hirikapo o te tamaiti, he taonga. Ki te kore e tika te manaakingia e ngā mātua, tērā te wā ka ātitirauhea i te puāwaitanga o te rau. Ngērā kaupapa katoa. (Haki Tuaupiki, 2013)
This project grew out of the desire of a kōhanga and a kura—Te Kōhanga Reo o Ngā Kuaka and Tōku Māpihi Maurea Kura Kaupapa Māori respectively—to enhance transitions between their two sites for tamariki and whānau. Although visits to Tōku Māpihi Maurea before beginning at the kura were available for Ngā Kuaka tamariki on acceptance for enrolment, the instigators of this project believed a more formal transition programme would be beneficial to tamariki and their whānau. The kōhanga and kura were interested in tamariki and whānau experiencing a more effective transition across the two environments and the learning and curriculum in those respective sites.
The kōhanga and kura approached researchers at the University of Waikato Te Kura Toi Tangata Faculty of Education with the research question below and together we developed the proposal. From the outset the project was collaborative, cross-sector, and involved researchers from the kōhanga, the kura and the university.
