title: New Zealand regions, 1986-2001: Household and families, and their dwellings

authors: Pool, Ian

subjects: households

abstract: Household structures and patterns of home ownership can have important implications for the wellbeing of populations. This paper explores regional differences in Household Structure and Home ownership for the period 1986 to 2001. Over this period there have been some major changes in the distribution of different household structures with a move away from the Two-parent household to other household types, such as Couple Only and Single-person households. Over the same period rates of home ownership have dropped. This paper shows that the patterns and trends for household structures and dwelling tenure vary significantly between regions. This reflects both overall national trends and inequalities between regions.

title: Onshore sandbar migration at Tairua Beach (New Zealand): Numerical simulations and field measurements

authors: van Maanen, Barend

subjects: nearshore sandbars

abstract: We observed the onshore migration (3.5 m/day) of a nearshore sandbar at Tairua Beach, New Zealand during 4 days of low-energy wave conditions. The morphological observations, together with concurrent measurements of waves and suspended sediment concentrations, were used to test a coupled, wave-averaged, cross-shore model. Because of the coarse bed material and the relatively low-energy conditions, the contribution of the suspended transport to the total transport was predicted and observed to be negligible. The model predicted the bar to move onshore because of the feedback between near-bed wave skewness, bedload, and the sandbar under weakly to non-breaking conditions at high tide. The predicted bathymetric evolution contrasts, however, with the observations that the bar migrated onshore predominantly at low tide. Also, the model flattened the bar, while in the observations the sandbar retained its steep landward-facing flank. A comparison between available observations and numerical simulations suggests that onshore propagating surf zone bores in very shallow water (< 0.25 m) may have been responsible for most of the observed bar behaviour. These processes are missing from the applied model and, given that the observed conditions can be considered typical of very shallow sandbars, highlight a priority for further field study and model development. The possibility that the excess water transported by the bores across the bar was channelled alongshore to near-by rip-channels further implies that traditional cross-shore measures to judge the applicability of a cross-shore morphodynamic model may be misleading.

title: Indigenous psychologies, fourth world peoples and the international literature: Finding ourselves in online abstracting and indexing databases

authors: Nikora, Linda Waimarie

subjects: indigenous psychologies

abstract: The presence and visibility of indigenous people and experience in the field of indigenous psychologies is vital to articulating existence, life, self-determination and future making. This article highlights examples of indigenous Psychology being both absent and present at the same time in OAD (online academic databases).
