title: Mindfulness-based stress reduction intervention in a sample of pregnant women in a rural area.

authors: Williams, Stephen Gordon

subjects: mindfulness

abstract: In this study, nine pregnant women in a rural area were assessed for a range of affective and mood disorders, as well as for coping self-efficacy and use of mindfulness in daily life. A mindfulness-based stress reduction intervention was implemented using “Healing Rhythms”, a commercially available computer-based mindfulness software programme, which uses biofeedback to assist in teaching self-regulation and mindfulness-based approaches for reducing stress. The programme was supplied already loaded onto laptops which were lent to participants for the study. Most participants showed improvements on measures of Trait anxiety and coping self-efficacy, with two participants whose scores at baseline met clinical criteria for depression dropping significantly to a non-clinical score at the end of the programme. Participants were interviewed and most reported satisfaction with using the programme, and a belief that it could be useful for other pregnant women especially where women felt challenged by stressors during pregnancy. The aim of the study was to identify whether a computer-based mindfulness programme for stress reduction would have utility and efficacy in a rural population. The results suggest that there were measureable gains for most participants, and that such a programme could be a supportive and helpful option for rural women who wish to learn how to better manage perinatal stress.

title: Logistic model trees

authors: Landwehr, Niels

subjects: computer science

abstract: Tree induction methods and linear models are popular techniques for supervised learning tasks, both for the prediction of nominal classes and numeric values. For predicting numeric quantities, there has been work on combining these two schemes into `model trees', i.e. trees that contain linear regression functions at the leaves. In this paper, we present an algorithm that adapts this idea for classification problems, using logistic regression instead of linear regression. We use a stagewise fitting process to construct the logistic regression models that can select relevant attributes in the data in a natural way, and show how this approach can be used to build the logistic regression models at the leaves by incrementally refining those constructed at higher levels in the tree. We compare the performance of our algorithm to several other state-of-the-art learning schemes on 36 benchmark UCI datasets, and show that it produces accurate and compact classifiers.

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.
