title: Experimental determination of natural convection heat transfer coefficients in an attic shaped enclosure

authors: Anderson, Timothy Nicholas

subjects: triangular enclosure

abstract: Heat transfer by natural convection in triangular enclosures is an area of significant importance in applications such as the design of greenhouses, attics and solar water heaters. However, given its significance to these areas it has not been widely examined. In this study, the natural convection heat transfer coefficients for air in an attic shaped enclosure were determined for Grashof Numbers over the range of 10⁷ to 10⁹. It was found that the measured heat transfer coefficients could be predicted to within 5% by Ridouane and Campo’ [1] equation (Eqn. 1) for natural convection in a triangular enclosure previously developed for Grashof Numbers in the range 10⁵ and 10⁶ . 
Nu = 0.286A-.286GR1/4 (1)
As such, it is suggested that this equation may be suitable for predicting the natural convection heat transfer coefficients in full scale attic enclosures.

title: Critical geographies of love as spatial, relational and political

authors: Morrison, Carey-Ann

subjects: affect

abstract: Geographers to date have resisted writing about feelings, affects, places and spaces of love. It is timely to put love on the geographical agenda. We begin by addressing the question ‘what does love do?’, and we review the work of geographers who have been thinking about love via a number of different theoretical lenses. We then argue for a consideration of love as spatial, relational and political. We prompt geographers to think critically about love in its entire multisensory, lived, embodied, felt and contradictory guises. Finally, the work of Ahmed, Sedgwick and Berlant is useful for furthering geographers’ insights on love

title: "That's the price we pay": Kaupapa Māori Programme stakeholder experiences of external evaluation

authors: Masters-Awatere, Bridgette

subjects: Evaluation

abstract: This thesis takes a critical approach to the evaluation of Māori social and health service provision progammes through an in-depth exploration of the dynamics, impacts and politics of such exercises within Māori communities, and upon relationships between Māori and the Crown, and its agents. Since the mid 1980s, New Zealand government devolved responsibilities that heralded a change in economic focus and provided a pathway for targeted service provision, such as social and health programmes, amongst communities. The combined shift to Neoliberal economics and the virtual hegemony enjoyed by right wing economic commentators, policy-makers and business leaders meant that newly anointed Māori service providers were not fully prepared for the subsequent rise in demand for narrowly defined accountability requirements that did not reflect Māori aspirations or values.

This study sought to critically engage with the experiences of stakeholders affected by an external evaluation of “By Māori, for Māori” services. Qualitative data capturing stakeholder narratives, demonstrated the complex relationships and range of emotions experienced by programme stakeholders. Four case studies contain stories that highlight: service provider relationships built on betrayal that contributed to programme tensions and influenced the design of the evaluation; different stakeholder information needs that shaped their expectation of an evaluation; service provider vulnerability when implementing cultural values with their funder, who then seeks financial gain from that knowledge, and; the close links of Kaupapa Māori programmes and their evaluations to socio-cultural and political agendas.

The cases highlight ways Māori evaluators operated from a reflexive approach that recognised two worldviews (Mātauranga Māori and the dominant models of Western social science) and sought to facilitate engaged evaluation relationships with different stakeholders. A proposed Cultural Confluent Evaluation model lays out the dynamics and tensions in an attempt to make visible the underlying agendas, but also the glossed ideologies of power and control attached to conventional evaluations. As existing programmes continue to be examined for their cultural responsiveness, and as new culturally-centred programmes are proposed, the need for culturally embedded evaluation is even more evident.
