title: Directional alignment and non-Gaussian statistics in solar wind turbulence

authors: Osman, Kareem T.

subjects: magnetohydrodynamics (MHD)

abstract: The magnetic and velocity field fluctuations in magnetohydrodynamic turbulence can be characterized by their directional alignment and induced electric field. These manifest as coherent spatial correlations which are measures of Alfvénicity and turbulence cascade strength, respectively. Solar wind observations and direct numerical simulations find that these distinctive correlations, caused by rapid relaxation processes that act to suppress nonlinearity, occur in localized spatial patches. This cellularization of magnetofluid turbulence is inconsistent with a superposition of Gaussian fields and could be related to spatial intermittency or other non-Gaussian statistics.

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: Translated identities: 'Pakeha' as subjects of the Treaty of Waitangi

authors: Goldsmith, Michael

subjects: Treaty of Waitangi

abstract: The politics of translation is clearly a perennial focus of debate in New Zealand, as shown by thematic links between the New Zealand social anthropology conferences at Waikato in 1990 and Auckland in 2004. Of the many issues of translation swirling around ongoing attempts to interpret the Treaty of Waitangi, a surprisingly neglected one concerns the identities of the people on behalf of whom the Crown signed the Treaty. The term 'Pakeha' appears only once in the Treaty, the question of whom it refers to is by no means straightforward, and it would be unwise to presume that it had the same range of meanings in 1840 as it does in present-day biculturalism. This point is demonstrated by a re-reading of historical material concerning the parties present at or implicated in the signing of the Treaty, including the so-called Pakeha Maori.
