title: Performance of a building integrated collector for solar heating and radiant cooling

authors: Anderson, Timothy Nicholas

subjects: building

abstract: Due to their limited temperature range, unglazed solar collectors have long been relegated to providing low cost heating in applications such as swimming pool heating systems. This limited temperature range is due to heat loss: firstly by convection to the surrounding air and secondly by radiant heat transfer to the cold sky. During the day an unglazed collector can be operated as a standard solar absorber to heat water in a storage tank. However, it is possible to take advantage of radiant cooling of unglazed solar collectors by operating them at night. Under night conditions when there is no solar radiation and the sky temperature is low, the collector can radiate heat to the sky and cool a cold storage tank to provide cooling in the building the following day. 
This study theoretically and experimentally examines the performance of a building integrated collector for heating and cooling and explores the contribution it can make to heating and cooling loads in typical New Zealand and Australian buildings.

title: World-view perspectives

authors: Whitehead, David

subjects: perspective

abstract: The foundation of a tolerant society is an ability to foster and
respond to the diversity of perspective among its people. Cognitive
psychologists have described how perspective influences information
processing, while our innate ability to adopt perspective has been established
by neuropsychology. Literature, through the use of point-of-view, together
with results from researchers adopting socio-cultural paradigms suggests
perspective is also a social construct. An ecologically-based framework is
described that provides cohesion to the temporal, spatial, universal and other
types of world-view perspective associated, predominantly, with indigenous
cultures. Culturally responsible types of creative and critical thinking are
evoked when world-view perspective is engaged while reading text and
reading the world. World-view perspective provides us with a means of
critiquing the construction of knowledge through the de-construction of
dominant discourses, re-valuing of indigenous world-views and reducing the
relational distance between indigenous and non-indigenous peoples.

title: Kaupapa Māori Science

authors: Stewart, Georgina Marjorie

subjects: Kaupapa Maori

abstract: This thesis investigates how Māori knowledge and language articulate with current discourses of Pūtaiao education, and possible alternative articulations. A Kaupapa Māori version of critical discourse analysis methodology is developed and applied to discourses relevant to Pūtaiao, or Māori-medium science education. This topic represents an intersection between language, science, education, and culture - fields which are all highly politically charged. Therefore, it is essential that a politically robust Kaupapa Māori position be taken in relation to the research topic. Not only the issues being investigated but the underlying research paradigm must be interrogated using Kaupapa Māori theory at each stage of the project.

The goal is to study the range of possible meanings for the notions of 'Pūtaiao' and 'Māori science' by exploring the relevant dialectical issues, critiquing the assumptions and positions taken on language, knowledge, identity and ethos, in order to inform further Pūtaiao curriculum development. The research project is a narration of the larger story of Pūtaiao education: what is the current situation, how did it come about, what theoretical issues have been influential in this process, and what possibilities are there for further development of Pūtaiao curriculum and pedagogy? 

The thesis research consists of a series of discourse analyses of varying levels of focus and intersection with Pūtaiao:
Wāhanga 1: Translated NCEA L1 science and mathematics examinations, and a traditional Taitokerau oral text;
Wāhanga 2: Māori science curriculum policy;
Wāhanga 3: Multicultural science education research;
Wāhanga 4: Curriculum politics, preventive linguistics, language of science;
Wāhanga 5: Mātauranga, rationality, philosophy of science.

Each analysis takes the form of a narrative history, based on a selected corpus of previously published scholarship (in Wāhanga 1, including numerical data and oral tradition) on the issue under examination, from a Kaupapa Māori perspective. Mainly in the first two chapters, analysis at times also draws on 'personal narrative' accounts of previously unpublished details relating to Pūtaiao.
 
Additionally, an investigation of various qualified notions of 'science' is undertaken, beginning in Wāhanga 2, concluding in Wāhanga 5, in order to explore the nature and boundaries of science as a system of knowledge, and its relationship to other types or systems of knowledge. 

Synopses are included of the following concepts and theoretical issues impacting on the discourses under analysis: 
Wāhanga 1: Ethnicity, 'race', critical theory, Kaupapa Māori theory. 
Wāhanga 2: Science, scientism, science ideology and anti-science.
Wāhanga 4: Identity, linguistic purism, the Sapir-Whorf hypothesis.

Informed by this research, in Wāhanga 5 an original model for the relationship between mātauranga and science is proposed, and the notion of Kaupapa Māori science/epistemology is explored. An analogy between the Sapir-Whorf hypothesis and multicultural science is used to draw together the cultural debates in language and knowledge, which are surmised to intersect at the level of discourse. 

The final chapter presents a re-articulation of Pūtaiao as the notion of Kaupapa Māori science education, and some recommendations for language and content knowledge in further development of Pūtaiao curriculum policy.
