title: Rapid global ocean-atmosphere response to Southern Ocean freshening during the last glacial

authors: Turney, Chris S.M.

abstract: Contrasting Greenland and Antarctic temperatures during the last glacial period (115,000 to 11,650 years ago) are thought to have been driven by imbalances in the rates of formation of North Atlantic and Antarctic Deep Water (the ‘bipolar seesaw’). Here we exploit a bidecadally resolved ¹⁴C data set obtained from New Zealand kauri (Agathis australis) to undertake high-precision alignment of key climate data sets spanning iceberg-rafted debris event Heinrich 3 and Greenland Interstadial (GI) 5.1 in the North Atlantic (~30,400 to 28,400 years ago). We observe no divergence between the kauri and Atlantic marine sediment ¹⁴C data sets, implying limited changes in deep water formation. However, a Southern Ocean (Atlantic-sector) iceberg rafted debris event appears to have occurred synchronously with GI-5.1 warming and decreased precipitation over the western equatorial Pacific and Atlantic. An ensemble of transient meltwater simulations shows that Antarctic-sourced salinity anomalies can generate climate changes that are propagated globally via an atmospheric Rossby wave train.

title: The lore and law of the playground

authors: Bateman, Amanda

subjects: rule-making

abstract: The pioneering work of the Opies has been an inspiration to many people interested in children’s play and games, academics and non-academics alike. Their books provide insightful details of how children interact and co-produce games through their rulemaking during everyday play, providing an awareness of the governance of social activities in the playground. In this article we explore the link between the work of the Opies and ethnomethodological and conversation analytic studies by identifying aspects of young children’s games and rules that have been eloquently explored in both domains. The thoughtful move to make the recordings of Iona Opie’s conversations with children about their games and associated rules available is fully utilised here, as excerpts are transcribed and analysed using conversation analysis. In so doing we demonstrate how conversation analysis can complement and extend the Opies’ significant work on children’s rule-making in play.

title: Ngā tai e rere nei i waho o Mauao

authors: Ngahuia, Dixon

subjects: Waiata Māori

abstract: "I te ao o ngā tūpuna he maha ngā kaupapa o taua wā i mau ki rō waiata, e whakaata mai ana i ngā kōrero-ā-iwi, ngā taukumekume i waenganui Māori, Pākehā, i waenganui hoki i ngā Māori anō. Nā wai hoki ka puta mai ngā herenga ki waenganui i tēnā iwi, i tēnā hapū, ka whakahoahoa tēnā iwi ki tēnā, te mutunga mai ka whānau ake ngā rōpū hou hei wānanga i ngā kaupapa i manawapātia. I pērā anō hoki ngā iwi o Tauranga Moana, ka huri atu ki tēnei iwi, ki tēnā hei huarahi tautoko āwhina mai i aua kaupapa nei. Ko ngā pupurihanga o ēnei taonga tuku iho e whakaahua mai ana i ngā kaupapa i waenganui i te ao Māori i aua wā, mō te iwi, mō te tangata kotahi rānei. Mā ēnei hoki kitea atu ai tā rātou titiro ki te ao i aua wā. 

He whiringa kōrero tēnei pepa mō tētehi waiata a Ngāi-TeRangi e whakamōhio ake ana i tētehi taukumekume i waenganui i a rāua ko Ngāti Kahungunu. Ka kitea i roto i ngā kōrero ka puta ngā huarahi whakapā atu ai ki tēnā iwi, hapū i waenganui, i waho atu rānei o Ngāi-TeRangi hei āwhina mai i te pupuri mana. Arā anō hoki te whakanui i ēnei momo waiata, ōna mana me te mātauranga Māori e pupū ake ana i konei. 

The waiata of our tūpuna Māori (Māori ancestors) capture in verse many issues and topics that were of significance at the time they were composed. They provide us with snapshots of iwi histories, including accounts of battles between Māori and Pākehā and between Māori and Māori. They tell us of alliances formed and reformed between tribes and hapū and of the reasons for these alliances. We see how the alignment and realignment of kin loyalties related to the issues of the day. Tauranga Moana iwi were not immune to such activities: tribal loyalties were chameleon-like, many alliances being pursued in relation to common interests. The ‘oral mapping’ of these local narratives that we find in waiata provides an illustration of topics relevant to individuals and to iwi: personal and collective statements about the ‘order’ of their day. They provide us with an insight into our ancestors’ ‘ways of seeing the world’. Above all, they are fundamental to the illustration and preservation of Māori knowledge. 
 
This paper presents an analysis of a Ngāi-TeRangi waiata tangi (lament) which relates to activities linking the iwi in a political stance against Ngāti Kahungunu. What is demonstrated is the intricate network of iwi and hapū involvement, within and without Ngāi-TeRangi, in the quest for honour. What is also demonstrated is the importance of waiata as significant literary achievements, as oral treasures."
