title: Automatic-Scoring Actigraph Compares Favourably to a Manually-Scored Actigraph for Sleep Measurement in Healthy Adults.

authors: Edgar, David Thomas

subjects: Monitoring

abstract: Introduction  Actigraphy has been used widely in sleep research due to its non-invasive, cost-effective ability to monitor sleep. Traditionally, manually-scored actigraphy has been deemed the most appropriate in the research setting; however, technological advances have seen the emergence of automatic-scoring wearable devices and software. Methods  A total of 60-nights of sleep data from 20-healthy adult participants (10 male, 10 female, age: 26 ± 10 years) were collected while wearing two devices concomitantly. The objective was to compare an automatic-scoring device (Fatigue Science Readiband™ [AUTO]) and a manually-scored device (Micro Motionlogger® [MAN]) based on the Cole-Kripke method. Manual-scoring involved trained technicians scoring all 60-nights of sleep data. Sleep indices including total sleep time (TST), total time in bed (TIB), sleep onset latency (SOL), sleep efficiency (SE), wake after sleep onset (WASO), wake episodes per night (WE), sleep onset time (SOT) and wake time (WT) were assessed between the two devices using mean differences, 95% levels of agreement, Pearson-correlation coefficients ( r ), and typical error of measurement (TEM) analysis. Results  There were no significant differences between devices for any of the measured sleep variables ( p  ≥0.05). All sleep indices resulted in very-strong correlations ( all r  ≥0.84) between devices. A mean difference between devices of <1 minutes for TST was associated with a TEM of 15.5 minute (95% CI =12.3 to 17.7 minutes). Conclusion  Given there were no significant differences between devices in the current study, automatic-scoring actigraphy devices may provide a more practical and cost-effective alternative to manually-scored actigraphy in healthy populations.

title: Paradoxical Performances of Subjectivities, Spaces and Art Gallery Postcards

authors: Robinson, Christine

subjects: gallery postcards

abstract: This thesis examines the relationship between art gallery postcards, subjectivities and domestic spaces. Feminist post-structuralist debates on memory, subjectivity and domestic spaces provide the theoretical framework for this research into taken-for-granted objects of the everyday. Empirical data came from interviewing nine women who buy, use and keep postcards and two New Zealand Art Gallery store managers. Some of the participants were interviewed more than once, while others extended their views by e-mail. Auto-ethnographic narrative is used to explore further the symbolic significance of an individual's postcard consumption.
This research focuses attention on the production of gendered subjectivities and domestic spaces through an aesthetic artefact. There are three points to my analysis. Firstly, I argue paradoxically the under-noticed seemingly trivial gallery postcard becomes a memory holder and therefore a significant artefact of symbolic value. Memories are potent, elusive fragments that become attached to a sound, smell, touch or sight. Catching sight of a postcard can trigger a chain of memory associations, which in turn constructs a sense of self through the remembering. Secondly, I contend that subjectivity is understood as fluid and multiple, evolving out of experience and interpretation. Memories formed from experience and connections made with people, place and things become associated with gallery postcards and serve as a catalyst for personal narratives which in turn can operate as tools for constructing subjectivities. Finally I suggest that domestic spaces are a product of relations that can be understood as existing within and beyond the home. Stretched domestic space can be produced by the display of gallery postcards in office spaces. The exploration of the art gallery postcard adds to the knowledges of everyday objects and their role and significance in constructing gendered subjectivities and spaces.

title: Toitū Te Whānau, Toitū Te Iwi: A Community Approach to English Transition

authors: Berryman, Mere

subjects: Maori

abstract: The research project presented in this thesis documents and describes the outcomes of effective whānau (immediate and extended family), kura (school), student, and researcher collaboration. The researcher became part of a whānau-of-interest (Bishop, 1996b) in 1998 and 1999 when she was invited by this community to help develop a suitable programme to assist highly competent Māori immersion students in their transition to a bi-lingual secondary school (the only option available in their community). The whānau wanted students to begin their secondary schooling with an improved competence in reading and writing in English but without compromising their competency in Maori language. Prior to this programme few of the students had received any formal instruction in the English language.
After a ten-week intervention implemented mainly outside the classroom, the researcher found that whānau tutors had effectively implemented the programmes and that all Year 8 students were able to read stories (in English) and talk about them (in English) at age appropriate reading levels. They also displayed improved rates of writing in English while maintaining their high fluency in reading and writing in Māori. The 10-week programme and results were replicated over a further three terms with the Year 7 and again with the Year 6 students. The study employed a multiple baseline across groups, design. A collaborative story gathered from participants at the end of the programme, together with these process and outcome data, strongly support the successful outcomes of this "participant driven" (Bishop, 1996b) programme.
