title: Positive Effects of Blue Light on Postural Control and Motor Coordination in Older Adults: A Pilot Study

authors: Beaven, Christopher Martyn

abstract: Purpose: Falls are a risk factor for mortality in older adults. Light interventions can improve cognitive function and performance in motor tasks, but the potential impact on postural control with relevance to falling is unknown. This study aimed to examine the effect of light on postural control, motor coordination, and cognitive functioning. 
Methods: Sixteen older adults participated in an intervention study that involved four counter-balanced sessions with blue-enriched light delivered visually and/or transcranially for 12 minutes. Postural control in three conditions (60 s eyes open, dual-task, and eyes closed), lower extremity motor coordination, and cognitive function were assessed. Area of sway (AoS), coordination, and cognitive function were compared between the groups via repeated-measured ANOVA. 
Results: Relative to placebo, visual blue-enriched light exposure clearly decreased AoS (d = 0.68 ±0.73; p =0.166) and improved reaction time in the motor coordination task (d = 1.44 ±0.75; p =0.004); however, no signicant effect was seen on cognitive function. 
Conclusion Blue-enriched light demonstrates a novel clinical approach to positively impact on postural control and lower-limb motor coordination in older adults. By impacting on metrics associated with fall risk, blue-enriched light may provide a clinically meaningful countermeasure to decrease the human costs of falls.

title: Composition portfolio

authors: Gilmour, Hannah Ruth

subjects: composition

abstract: This collection of original compositions shows a range of themes and styles.
Each piece portrays a different concept or idea I have grappled with during the year of composition.  Three Angles of Anticipation is a set of three diverse orchestral works each based on the theme of waiting.  In contrast, Sad Songs for a Rainy Day and a Broken Heart is a collection of six short pieces written for solo piano which explore the themes of grief and memories.  Land of Promise? combines acoustic and electroacoustic techniques to create a work questioning how much we are informed of New Zealand's history, whereas Telemachus is a dramatic work about a Monk killed in a gladiator arena.  To conclude, the electroacoustic tape work Ode to a Cricket is a set of three pieces created from the sample of a cricket call. It explores the theme of paying attention to the small and seemingly insignificant details of our world.

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.
