title: Pretty difficult: Implementing kaupapa Māori theory in English-medium secondary schools

authors: Bishop, Russell

subjects: Te Kotahitanga Project

abstract: Developed in New Zealand some twenty years ago, kaupapa Māori has had a successful impact in education, notably in Māori-medium settings such as kōhanga reo, kura kaupapa Māori and wharekura. However, in mainstream educational settings, where the vast majority of Māori children continue to be educated, achievement disparities between Māori and their non-Māori peers persist. This article focuses on Te Kotahitanga, a large-scale kaupapa Māori school reform project that seeks to address educational disparities by improving the educational achievement of Māori students in mainstream schooling. Experiences with implementing Te Kotahitanga would suggest that reforming mainstream educational practices along kaupapa Māori lines is not easy. This article examines three main impediments encountered in attempts to implement the Te Kotahitanga project in mainstream schools: confusion about the culture of the Māori child; uneven implementation of the project; and problems with measuring student progress. For the project’s aims to be realised, professional development needs to be ongoing, iterative and responsive.

title: The spatial equity and sustainability of general practitioner services: A mixed methods analysis of the Waikato DHB region

authors: Whitehead, Jesse

subjects: spatial equity

abstract: The New Zealand Primary Health Care Strategy states that quality primary health care is the first level of contact with the health system and should be universally accessible. Effective primary health care is an essential component of health systems, and is associated with more equitable distributions of health outcomes. However, not all New Zealanders have ready access to primary health care. For instance, adult residents of the Waikato region, and in particular Māori, have higher levels of unmet need for primay care than others. Improving the spatial equity of health services is a key step in achieving health equity. Health systems should contribute to achieving health equity and maintaining sustainable and equitable services into the future. 

This thesis research examines the spatial equity and sustainability of general practitioner (GP) services in the Waikato DHB region, using a mixed-methods approach to identify not only where inequities exist, but why they occur. A conceptual framework establishes a foundation for examining spatial equity and sustainability in New Zealand. Next, a systematic literature review identifies common definitions and measures of spatial equity. Primary Health Organisation (PHO) enrolment data is used to examine patterns of patient enrolment at GP services, and a range of health needs indicators were assessed for their suitability in the New Zealand primary care context. These findings inform the development of a Geographic Information Systems (GIS) model of spatial accessibility that is tailored to the Waikato District Health Board (DHB) context. The GIS model is then used, in combination with in-depth qualitative interviews, to examine the spatial equity and sustainability of GP services in the Waikato DHB region. 

Key findings include that spatial equity is commonly defined as a ‘need-based distribution of resources’, which can be quantified using a range of statistical and geospatial measures and techniques. PHO enrolment analysis revealed that most patients do not enrol with their closest service, and that the size of the ‘catchment area’ served by GP clinics varies with rurality. Analysis of indicators of health need suggest that ‘Ambulatory Sensitive Hospitalisations’ are a robust indicator; however, area-level socioeconomic deprivation is also strongly associated with other indicators of need and data is more widely available to researchers. Mixed-methods analysis suggests that GP services are not distributed equitably within the Waikato DHB region and that key barriers to access include the affordability, appropriateness, and availability of services. New Zealand’s history of colonisation and discrimination are identified as fundamental drivers of health inequity. Furthermore, population growth and ageing suggest that current levels of access to GP services are unlikely to be maintained in the future, while participants identify key economic, professional, organisation, and social dimensions that influence service sustainability in New Zealand.

title: The anatomy of an andesite volcano: a time-stratigraphic study of andesite petrogenesis and crustal evolution at Ruapehu Volcano, New Zealand

authors: Price, Richard C.

subjects: andesite

abstract: Ruapehu, New Zealand’s largest active andesite volcano, is located at the southern tip of the Taupo Volcanic Zone (TVZ), the main locus of subduction-related volcanism in the North Island. Geophysical data indicate that crustal thickness increases from <25 km within the TVZ to 40 km beneath Ruapehu. The volcano is built on a basement of Mesozoic meta-greywacke, and geophysical evidence together with xenoliths contained in lavas indicates that this is underlain by oceanic, meta-igneous lower crust. The present-day Ruapehu edifice has been constructed by a series of eruptive events that produced a succession of lava flow-dominated stratigraphic units. In order from oldest to youngest, these are the Te Herenga (250–180 ka), Wahianoa (160–115 ka), Mangawhero (55–45 ka and 20–30 ka), and Whakapapa (15–2 ka) Formations. The dominant rock types are plagioclase- and pyroxene-phyric basaltic andesite and andesite. Dacite also occurs but only one basalt flow has been identified. There have been progressive changes in the minor and trace element chemistry and isotopic composition of Ruapehu eruptive rocks over time. In comparison with rocks from younger formations, Te Herenga eruptive rocks have lower K₂O abundances and a relatively restricted range in major and trace element and Nd–Sr isotopic composition. Post-Te Herenga andesites and dacites define a Sr–Nd isotopic array that overlaps with the field for TVZ rhyolites and basalts, but Te Herenga Formation lavas and the Ruapehu basalt have higher ¹⁴³Nd/¹⁴⁴Nd ratios. The isotopic, and major and trace element composition of Te Herenga andesite can be replicated by models involving mixing of an intra-oceanic andesite with a crustal component derived from a meta-igneous composition. Post-Te Herenga andesites show considerable variation in major and trace element and Sr and Nd isotopic compositions (⁸⁷Sr/⁸⁶Sr ranges from 0•7049 to 0•7060 and ¹⁴³Nd/¹⁴⁴Nd from 0•51264 to 0•51282). The range of compositions can be modeled by assimilation–fractional crystallization (AFC) involving meta-greywacke as the assimilant, closed-system fractionation, or by mixing of intra-oceanic andesite or basalt and a meta-greywacke crustal composition. Plagioclase and pyroxene compositions vary over wide ranges within single rocks and few of these have compositions consistent with equilibration with a melt having the composition of either the host-rock or groundmass. The ⁸⁷Sr/⁸⁶Sr compositions of plagioclase also vary significantly within single whole-rock samples. Glass inclusions and groundmasses of andesitic rocks all have dacitic or rhyolitic major and trace element compositions. The application of various mineral geothermometers and geobarometers indicates pre-eruption temperatures between 950 and 1190°C and pressures ranging from 1 to 0•2 GPa. These pressure estimates are consistent with those obtained from xenolith mineral assemblages and geophysical information. Plagioclase hygrometry and the paucity of amphibole are indications that melts were relatively dry (< 4 wt % H₂O). Magmas represented by Ruapehu andesites were dacitic or rhyolitic melts carrying complex crystal and lithic cargoes derived from the mantle and at least two crustal sources. They have evolved through a complex interplay between assimilation, crystal fractionation, crustal anatexis and magma mixing. Parental magmas were sourced in both the mantle and crust, but erupted compositions very strongly reflect modification by intracrustal processes. Geochemical variation in systematically sampled lava flow sequences is consistent with random tapping of a complex plumbing system in which magma has been stored on varying time scales within a plexus of dispersed reservoirs. Each magma batch is likely to have had a unique history with different sized magma storages evolving on varying time scales with a specific combination of AFC and mixing processes.
