title: An Interactive User Management System for Multilingual Documents: A case study of the Pei Jones collection

authors: Cader, Papitha

subjects: Greenstone Digital Library

abstract: Can general purpose DL software architecture be designed to provide a flexible environment that supports both the management and end-user roles through a single unified web interface? In particular we take the collected correspondence of the Māori scholar Dr. Pei Jones and undertake case study of how this approach can be applied in a practical way.

title: Telomere length in early childhood is associated with sex and ethnicity

authors: Ly, Kien

subjects: Science & Technology

abstract: Telomeres are repetitive DNA sequences at the end of chromosomes that function to protect chromosomes from degradation. Throughout the life course, telomere length decreases with age and is influenced by environmental factors and health conditions. This study aimed to determine the relative telomere lengths in a diverse cohort of about 4000 four-year-old children in New Zealand. Linear regression was used to investigate the relationship between telomere length, child gender, ethnicity, paternal age and deprivation. We observed substantial variation in telomere length according to sex and self-identified ethnicity. Telomere length was longer in females compared to males (coefficient of 0.042, 95% confidence interval (CI) 0.024–0.060). European children had shorter telomere than both the indigenous Māori (coefficient of 0.03, CI 0.007–0.055) and Pacific children (coefficient of 0.15, CI 0.12–0.18). The data suggest that telomere lengths are highly variable and variability between individuals arise from early age, influenced partly by sex and ethnicity. Longer telomeres in indigenous Māori and Pacific children may reflect the heritability of telomere length in genetically less complex populations. This study increases our understanding of telomere dynamics in young children since the majority of telomere studies are conducted in adults.

title: Ecology of the invertebrate predatory fauna across Centre Bank, Tauranga Harbour

authors: Putt, Fiona Gloria

subjects: Centre Bank

abstract: The distribution, abundance, population size structure and behaviour of three common invertebrate predators were studied on Centre Bank, the flood-tidal delta of Tauranga Harbour. The study assessed the role of the predators in controlling the distribution and abundance of bivalve shellfish and provided information concerning the biology of Centre Bank for Port of Tauranga Ltd.
Two broad-scale surveys were conducted to describe the broad-scale spatial patterns of Patiriella regularis, Coscinasterias calamaria and Cominella adspersa. Results found P. regularis was the numerically dominant species across Centre Bank and it maintained a widespread distribution over the sampling period. C. calamaria was of low abundance and typically exhibited a patchy distribution. C. adspersa was also found to be of low abundance and similarly distributed as C. calamaria. Size structures of all 3 species comprised mostly adults in both surveys.
Temporal monitoring at finer scales was undertaken, two-monthly, to describe small-scale spatial patterns. P. regularis was found at similar densities to that of the large-scale surveys and it was the most prevalent species across the grid; C. calamaria was present at higher abundances within a small patch of the grid and appeared stable over time. C. adspersa was initially absent from the grid, but became more abundant and widespead over the 9 month sampling period.
Investigations included monitoring the natural movement behaviour of C. adspersa in relation to tidal currents and the body condition. Results showed the directions moved and distances displaced by C. adspersa may be influenced by the rate and direction of current movement and therefore potentially influencing the dispersal ability of C. adspersa, in relation to available prey. An experiment to determine the body condition of C. adspersa in the field suggested that food deprivation may be less detrimental than first realised, or that C. adspersa is able to feed on a greater variety of food types than known of.
Little evidence was found that indicated predation was an important mechanism controlling bivalve populations across Centre Bank. However, predators may be potentially important as scavengers of decaying or dead organisms. Their predatory activities may also provide shell substrate for macroalgae, and this, in combination with dense aggregations of C. calamaria, appeared to provide habitat for small fishes.
