title: Further pterocellins from the New Zealand marine bryozoan Pterocella vesiculosa

authors: Prinsep, Michèle R.

subjects: pterocellins

abstract: Four new alkaloids, pterocellins C−F (1–4), have been isolated from the New Zealand marine bryozoan Pterocella vesiculosa. Structural elucidation was achieved through NMR spectroscopic and mass spectrometric analysis and comparison of spectroscopic data with that of the known compounds pterocellins A and B. The biological activities of 1–4 were assessed in a number of different assay systems and compared with those of pterocellins A and B.

title: Appendix: The GL(n) pack Manual

authors: Broughan, Kevin A.

subjects: mathematics

abstract: This appendix is the manual for a set of functions written to assist the reader to understand and apply the theorems on GL(n, R) set out in the main part of the book. The software for the package is provided over the World Wide Web at http://www.math.waikato.ac.nz/~kab  and is in the form of a standard Mathematica add-on package. To use the functions in the package you will need to have a version of Mathematica at level 4.0 or higher.

title: Kaum tuatanga the changing roles of kaum tua in Ng ti Rehua: Future directions

authors: Davies, Sydney Henare

subjects: Indigenous psychology

abstract: This study looks at the roles of kaum tua and investigates how these roles have changed over time. With the ageing Māori population and the reported importance of kaum tua roles in the wellbeing of Māori communities, the findings of this study provide an insight into the possible future direction of these roles. The study was conducted with the assistance of members of one hapu (N=47) that were 65 years of age and over. The study was by interview, utilising a semi-structured questionnaire with both open ended and closed questions. Narratives from participants was analysed and compared to the roles of kaum tua that were found in the literature, namely; Leadership, cultural knowledge, dispute resolution, protection and nurturing of young, provide spiritual and other guidance, social control, provide rituals, preserve te reo Māori and live active and healthy lives. Findings of this research supported the roles found in the literature. The roles of kaum tua still exist but may have diminished over time. The change in roles is in the adaptation to meet the needs of the time period while maintaining the core values of each role and providing a continuation of practices.
