title: Performance of coloured solar collectors

authors: Anderson, Timothy Nicholas

subjects: solar collector

abstract: The use of solar collectors with coloured absorbers for water heating is an area of particular interest when considering their integration with buildings. By matching the absorber colour with that of the roof or façade of the building, it is possible to achieve an architecturally and visually pleasing result. Despite the potential for the use of coloured absorbers very little work has been undertaken in the field.
In this study, the thermal performance of a series of coloured, ranging from white to black, water heating solar collectors is examined. Subsequently, the annual solar fraction for typical water heating systems with coloured absorbers is calculated. The results show that coloured solar collector absorbers can make noticeable contributions to heating loads. Furthermore, although their thermal efficiency is lower than highly developed selective coating absorbers, they offer the advantage of sensitive integration with buildings.

title: Individualism and the public good: a case study in childhood immunisation

authors: Gower, Suzanne Elizabeth

abstract: The election of the Fourth Labour Government in July 1984 marked a turning point in New Zealand’s political economic history, ushering in the rise of the individualism which was fundamental to the prevailing philosophy of neo-liberal rationalism. In addition, however, to the widely recognised individualism in the political economy there was also a rising attitude of individualism within New Zealand's civil society. 

This thesis examines the development of New Zealand’s childhood immunisation policy, the National Immunisation Strategy, as a case study in determining the impact both neo-liberal and civil individualism had on the development of a policy with implications for the public good.
 
The thesis describes the public policy environment m which the National Immunisation Strategy was developed, examining the changes individualism wrought in both New Zealand’s political economy and in civil society. It traces the impact this had in turn on health sector reform, and later on the development of National Immunisation Strategy. 
The research uses qualitative methods in the examination of the policy-making process. It examines the literature surrounding childhood immunisation policy in New Zealand, key documents related to the policy-making process and findings of interviews with key informants involved in the policy-making process variously as officials, expert participants, and interested observers. 

The thesis concludes that both neo-liberal and civil individualism had a role in shaping not just the National Immunisation Strategy, but also the environment in which it was implemented. Furthermore, the failure of the strategy to improve childhood immunisation coverage rates and prevent epidemics of vaccine preventable diseases can be linked to the impact individualism had on both the policy development process and the National Immunisation Strategy.

title: "Ko au te whenua, ko te whenua ko au:" A Māori housing development process

authors: Fletcher, Marcus Anzac Kewene

subjects: Māori

abstract: Tangata whenua (People of the land/Indigenous people of Aotearoa) are being recognised as emerging property and land developers in Aotearoa New Zealand (hereafter, Aotearoa). Literature and practice demonstrates how Māori are developing housing in different ways than traditional developers, supporting the wellbeing of whānau (families), hapū (sub-tribes) and iwi (tribes), while contributing to addressing the national housing crisis. The distinctiveness of these approaches are important to understand if we want to deepen our knowledge of urban development and the modelling of housing markets in Aotearoa. This thesis aims to reveal, codify and examine Māori decision-making processes relating to how and why we develop housing in Aotearoa and the values and principles that inform these approaches. Utilising Kaupapa Māori Theory and taking an insider/whānaunga (relatives) approach to the research, four whakawhiti kōrero sessions with Waikato whānau and kaimahi (workers) were undertaken to better understand how and why Māori develop housing and the processes and rationalities at play. The thesis has three contributions for academia, environmental planning and the housing sector in Aotearoa: insights into the values and rationalities that influence Māori urban development; the introduction of a Māori housing development framework; and insights into how the framework may be utilised to contribute towards more accurate and sophisticated agent-based modelling (ABM) or urban growth modelling.  

The findings and discussion identified six prominent values that Māori utilise to develop housing: kaitiakitanga, manaakitanga, orangatanga, whānaungatanga, ūkaipōtanga and rangatiratanga. Being rooted in Māori knowledge and epistemology essentially demands differing rationalities for when Māori undertake housing development, which are placed within an overarching framework. The framework represents a new tool to disrupt the current understanding of ‘developers’ as a single entity with a defined pathway that influences all development behaviour. Moreover, it demonstrates how whānau, hapū and iwi draw on the established learning and guidance of our tūpuna (ancestors) and the strides taken to reclaim tino rangatiratanga (self-determination). The thesis argues that academics, environmental practitioners and the housing sector should re-examine their understanding of developers in Aotearoa to become more pluralistic, which may present new challenges and opportunities for ABM and urban growth modelling. This framework argues some aspects may have potential to be incorporated into these technical analyses, while other aspects should be considered in the context of Māori and Indigenous Data Sovereignty to protect the contributions and mana of the participants within this thesis, or resist the ability to be captured altogether.
