title: Health, Culture, and Lifestyle in Contemporary Tonga:  With Particular Reference to Diabetes and Diet

authors: Forde, Jacinta Maria

subjects: Tonga

abstract: Over recent decades there has emerged a significant literature regarding the effects of development and globalisation on the culture of Pacific Islanders. It often has emphasised the alarming rate at which non-communicable diseases and related health complications have increased, presumably due to changes in lifestyles. The aim of this thesis is to report on a research project that investigated the contradictory effects that globalisation and development have had on the people of Tonga, particularly in respect to their way of life and how they negotiate the relationship between tradition and modernity. It is informed by a period of ethnographic fieldwork undertaken by the researcher with three families in Tonga, as well as unstructured interviews with members of the Tongan community in Tonga and New Zealand. The study especially explores the link between the shift away from traditional lifeways and increasing ill health, with a focus on the link between diabetes and diet, and more generally Tongan understandings of ‘health’ and non-communicable diseases and their treatments.

title: Stratigraphy, chronology, and correlation of the Plio-Pleistocene (c. 2.2-0.8 Ma) Kauroa Ash sequence, western central North Island, New Zealand

authors: Horrocks, Joanna L.

abstract: The Kauroa Ash beds (K-beds) comprise a 12-20 m-thick sequence of extremely weathered, clay-rich (40-95% <4 μm clay) beds of tephra and loess, and associated paleosols. Found in isolated remnants throughout the western central North Island, the sequence comprises 15 defined members, with as many as 44 constituent macroscopic beds. The type site, ‘Woodstock’, near Raglan, is the most comprehensive sequence known, but other sites (e.g. Papakura Creek and Tiritirimatangi Peninsula) contain units not found or poorly defined at Woodstock. 

Field properties as well as magnetic susceptibility measurements and particle-size analysis characterise the facies in the sequence. Field properties (in particular colour, consistence, macrofabric) describe the lithostratigraphy. The sequence contains five interpretive (i.e. genetic) ‘facies’: paleosols, primary tephra, very weathered tephra (possibly composite beds), loess and ‘tephric loess’ beds. At least seven loess beds are (newly) identified in the sequence: K4a, K5, K6ai, K8ai, K8bi, K10a and K14ai.

Mass-specific susceptibility and frequency-dependent susceptibility results partly conform to established models (developed mostly on Chinese loess-paleosol deposits) of susceptibility enhancement in paleosols and depletion in loess. Many parts of the sequence do not appear to conform to this model and the results more closely resemble the inverse relationship found on Alaskan loess-paleosol beds. Frequency-dependent susceptibility is reliable in delineating paleosols by their ‘ultrafine’ ferrimagnetic mineral content, and citrate-bicarbonate-dithionite treatments successfully remove all iron oxides so that remeasurement of susceptibility isolates a strictly ‘pedogenic’, rather than lithogenic, fraction. 

Laser diffraction particle-size analysis shows that the Kauroa Ash beds are texturally reasonably homogenous. They have bimodal particle-size distributions with the most dominant mode at around 11.25 ɸ inferred to be the product of intense and prolonged weathering. Other modes are variously centred on 7-8.5 ɸ and, despite weathering and pedogenesis, have some relationship to the original depositional particle-size distributions because trends between facies (i.e. genetic units) are delineated. Principal components analysis objectively characterises these modes as (Wentworth size classes) ‘very fine clay’ and ‘coarse silt’, although there is no proportional relationship between them, supporting a post-depositional origin for the former mode. 

The chronology of the sequence, previously poorly defined, is greatly improved by a combination of tephrochronologic correlations, fission-track dating, and paleomagnetism. Five zircon fission-track dates provide independent age ‘spikes’ and range from 2.24 ± 0.29 Ma in the basal member, K1, to 1.28 ± 0.11 Ma for the distal ignimbrite unit K12a. Paleomagnetism is invaluable in providing additional age information. The top of the sequence, member K15, is dated as >0.78 Ma (Brunhes-Matuyama boundary) because of its reversed polarity; two episodes of normal polarity are found in beds K14b and K2b and are inferred to represent the Jaramillo (1.07-0.99 Ma) and Olduvai (1.95-1.79 Ma) subchrons, respectively. Beds underlying the Kauroa Ash sequence are also of normal polarity, indicating that they were deposited in the Gauss Chron (>2.6 Ma). 

Identification and correlation of tephras by conventional means (fingerprinting by their lithological or geochemical properties) is impossible in the Kauroa Ash sequence because the beds have no remaining volcanic glass, which has instead been altered to an assemblage of authigenic phases (clays) by weathering and pedogenesis. However, a new technique analysing fresh glass found as melt inclusions in quartz grains is successful in circumventing this problem. Inclusions represent samples of non-degassed magma that became entrapped during phenocryst growth prior to eruption. The glass has remained unaltered because it is hermetically sealed in a chemically resistant phenocryst, which has protected it from weathering processes. Electron microprobe analysis of the glass inclusions yield results which are wholly reasonable for glass (totals ranging from 93-97%; low standard deviations of <1 %), and a number of provisional correlations are established by comparing the major element composition of Kauroa Ash tephra beds with those of proximal deposits. The Kauroa Ash sequence may contain deposits correlated with at least seven major TVZ eruptions, in many cases expanding the known extent of the (distal) deposit and, for the first time answering the question as to the origin of the Kauroa Ash beds. 

These correlations, together with an improved chronology, enable the Kauroa Ash sequence to be placed in a regional stratigraphic framework alongside other New Zealand Plio-Pleistocene sequences such as those in the Wanganui Basin, Wairarapa, Cape Kidnappers and Port Waikato. Using paleosols as chrono- and climatostratigraphic entities (correlated to warm periods in global climate), the sequence can also be placed alongside a global reference, the marine oxygen isotope stratigraphy. A further correlation to the Chinese loess-paleosol record suggests that large parts of the Kauroa Ash sequence were deposited in an incremental manner akin to deposition of loess, so that the sequence is not only a record of TVZ volcanism, but also of Plio-Pleistocene paleoclimate.

title: Mā Muri Ko Mua: An introduction to the issues associated with the translation of the Pene Haare manuscript

authors: Tipene, Jillian

subjects: translation

abstract: Keywords: translation; translation theory; translation practice; Ngakuru Pene Haare; Te Rarawa; manuscript; Māori-English translation; ethically grounded translation.

In September 2007, a copy of a typewritten transcript of a manuscript dated 1923 and written by Ngakuru Pene Hare was given to a member of staff of the University of Waikato by Stephen Burke and Bella Wade, descendants of the author, who requested that the University provide a scholarly treatment and translation into English of the text. Also provided later were copies of letters written by the author and a copy of the original handwritten manuscript. The original manuscript, written in the Te Rarawa ki Hokianga dialect of te reo Māori of the author's time, consists of 239 leaves and contains accounts of at least 62 Ngāpuhi battles, most of which took place between 1820 and 1840. 

The research reported here seeks to identify issues and problems that must be addressed if a competent and ethically-grounded translation is to be produced.  Among the issues and problems identified are a number of critical ones. These include the paucity of information that is publicly available about the author, the context in which he lived and worked and the events about which he wrote. Also identified as being problematic are aspects of the text itself. Thus, for example, many of the conventions associated with contemporary writing in Māori (such as paragraphing and the signalling of word and sentence boundaries) are applied only sporadically. Some of the words and expressions used are archaic and/or esoteric, and symbolism that is deeply culturally-embedded characterises much of the text. Also of significance is the impact of writing on conventions associated with the oral transmission of information. The author's intention in producing the text is also identified as being of fundamental importance in relation to the process and product of translation, as are issues associated with the putative readership of that translation. Of paramount importance is the sacred and sensitive nature of the text itself and much of its content. 

In addressing these issues, a wide range of sources are drawn upon. These include the text itself and the transcription of the text, letters and other material written by, or directly influenced by the author, photographs that reveal important information about him, and a wide range of sources of information and opinion (written and oral) about the author and/ or the times and places in which he lived and the events about which he wrote. Also drawn upon is literature in the areas of linguistics and discourse analysis and the theory and practice of translation, including literature written by the growing number of Māori scholars who have focused on issues associated with translation involving Māori and English.

Among the recommendations made are that the translation, a gloss translation that includes explanatory notes, be undertaken, with tikanga Māori as guiding principles, under the mentorship of knowledgeable elders and in consultation with those to whom the manuscript belongs.
