title: StoneD: A bridge between Greenstone and DSpace

authors: Witten, Ian H.

subjects: computer science

abstract: Greenstone and DSpace are widely-used software systems for digital libraries, and prospective users sometimes wonder which one to adopt. In fact, the aims of the two are very different, although their domains of application do overlap. This paper describes the systems and identifies their similarities and differences. We also present StoneD, a stone bridge between the production versions of Greenstone and DSpace that allows users of either system to easily migrate to the other, or continue with a combination of both. This bridge eliminates the risk of finding oneself locked in to an inappropriate choice of system. We also discuss other possible opportunities for combining the advantages of the two, to the benefit of the user communities of both systems.

title: Effect of nutrient enrichment and turbidity on interactions between Microphytobenthos and a key bivalve: implications for higher trophic levels

authors: Hope, Julie A.

subjects: Science & Technology

abstract: Benthic diatoms are a high-quality food resource providing essential fatty acids to benthic grazers. Different stressors may alter the proportion of diatoms and other microalgae and thus can affect the quality as well as quantity of food available to benthic consumers. Microphytobenthos (MPB) lipid biomarkers were assessed in a field experiment to elucidate changes to the biosynthesis of fatty acids (FA) under nitrogen (N) enrichment (three levels) at eight intertidal sites that spanned a turbidity gradient. Influences on the flow of carbon and energy were determined using FA biomarkers of a functionally important deposit-feeding tellinid bivalve (Macomona liliana). Site-specific effects of N enrichment were detected in MPB quantity and quality measurements. Enrichment generally increased MPB biomass (chl a) across all sites, while the proportion of diatom associated fatty acid biomarkers was more variable at some sites. Analysis of sediment FA biomarkers and environmental variables suggested that changes to the microbial community composition and quality were related to water clarity and mud content of the bed. The ability of the MPB to utilize the increased nitrogen, as indicated by the resource use efficiency index, was also important. Despite the increase in MPB biomass, lipid reserves in the tissue of M. liliana, a primary consumer of MPB, were reduced (by up to 6 orders of magnitude) in medium and high N addition plots compared to control plots. Further, the nutritional quality of the bivalves to higher trophic levels [indicated by a lower ratio of essential FAs (ω3:ω6)] was reduced in high treatment plots compared to control plots suggesting the bivalves were adversely affected by nutrient enrichment but not due to a reduction in food availability. This study suggests anthropogenic nutrient enrichment and turbidity may indirectly alter the structure and function of the benthic food web, in terms of carbon flow and ecosystem productivity. This may indirectly change the interactions between MPB and key bivalves as suspended sediment concentrations and nutrient enrichment continue to increase globally. This has implications for various ecosystem functions that are mediated by these interactions, such as nutrient cycling as well as primary and secondary production.

title: Matariki, commodity culture, and multiple identities

authors: Hardy, Ann

subjects: Matariki

abstract: The event known as Matariki, the rising of the Pleiades in winter, which Māori take as the mark of the beginning of a new year, was not a strong feature of the wider public sphere for most of the 20th century. Since 2001, however, when Te Taura Whiri, the Māori Language Commission, published an explanatory booklet with the aim of reviving interest in Matariki as an aide to the maintenance of te reo, it has been promoted by several quasi-governmental institutions, especially the national museum, Te Papa, as a winter festival for all New Zealanders. Its main public presence to date has been through media products: posters, banners, websites, television programmes, newspaper features, calendars, some theatrical performances and physical commemoration ceremonies.

The larger project, of which this paper represents an initial descriptive and positioning phase, is a continuation of the researcher's long-standing interest in the intersections of religiosity, culture, and media as they are active in the environment of Aotearoa New Zealand. It assumes, building on theorists such as Bellah and Lundby that the creation of such festivals is an act of 'civil religiosity' that attempts to create and strengthen national community around a set of numinous symbols.
However, the development of an enterprise such as Matariki is pursued in a complex political field, where broad agreement across various factions is needed before the festival can take on an enduring material and symbolic existence. In investigating the factors that will determine the future of Matariki it is relevant to consider the interaction of three factors in particular: the ethno-political history of New Zealand; the characteristics of contemporary reflexive spirituality, which are intertwined with commodificatory tendencies and thirdly, the impacts of increasing globalisation on the parameters of identity-formation for citizens in late-modern societies.
