title: Aqueous copper bioavailability linked to shipwreck-contaminated reef sediments

authors: Hartland, Adam

subjects: Science & Technology

abstract: Pollution from the grounding or sinking of ships can have long lasting effects on the recovery and dynamics of coastal ecosystems. Research on the impact of copper (Cu) pollution from the 2011 MV Rena shipwreck at the Astrolabe Reef (Otaiti), New Zealand, 5 years after the grounding, followed a multi-method and multi-disciplinary approach. Three independent measures of aqueous Cu using trace-element-clean-techniques substantiate the presence of high total, total dissolved (<2 µm) and elevated bioavailable Cu in the water column immediately above the aft section of the wreck where the highest sedimentary load of Cu was located. Intermittently elevated concentrations of strong Cu-binding ligands occurred in this location, and their binding strength was consistent with ligands actively produced by organisms in response to Cu induced stress. The recruitment of benthic invertebrates was modified at the high-Cu location. Taxonomic groups usually considered robust to pollution were restricted to this site (e.g. barnacles) or were the most abundant taxa present (e.g. foraminifera). Our results demonstrate that Cu-contaminated sediments can impose a persistent point source of Cu pollution in high-energy reef environments, with the potential to modify the composition and recovery of biological communities.

title: Retail value stream management

authors: Powell, Mark

subjects: retail industry

abstract: In this paper the authors translate, integrate and synthesise supply chain management concepts for application in the retail sector. Although a number of best practice retail supply chains have been well popularised, the majority of retailers are struggling with applying the traditionally manufacturing-focussed concepts of supply chain management. This paper provides a comprehensive toolkit, comprising seven retail value stream principles specifically aimed at translating supply chain management for retailers. These seven principles are focus on the customers' perception of value; engineer value streams to match customer requirements; remove non-value adding waste; maximise customer pull; optimise the total supply chain; develop win-win supply chain relationships; and continuously review and improve, striving for perfection. Case applications of these principles clearly highlight the significant improvements possible in retail supply chain competence and the resultant competitiveness.

authors: Apanui, Ngahiwi

subjects: Panuku

abstract: He aha te Māori? He aha i kīia ai tētahi āhuatanga, tētahi mahi, tētahi tangata, tētahi whakahaere rānei he Māori? Ko te whāinga o te rangahau nei he rapa huarahi e āhei ai te whakautu i ēnei pātai. Me te huhua hoki o te whakaaro mō ēnei pātai, i huri ahau ki ngā mātanga, ngā pūkenga hoki o te ao mātauranga Māori hei taunaki i te whakautu ki te pātai. 
Ka tūhura te rangahau nei i te rētōtanga o te ao Māori, ka titiro hoki ki te āhua i Māori ai ētahi āhuatanga me te whakautu, he ahurea Māori i Māori ai tētahi āhuatanga, tētahi mahi, tētahi tangata, tētahi whakahaere rānei – ko te pū ahurea Māori tēnei. Ka titiro anō hoki te rangahau nei ki te whakaaro Māori hei tūāpapa mō te pū ahurea Māori, te wāhanga ki ngā kaupapa tuku iho me te whakaatu a te tikanga i te kaupapa. 
Ko te hua o te rangahau nei, he tuku i te rauemi e taea ai te tangata te tautuhi me te ine i te pū ahurea Māori hei ārahi i te aromātaitanga o ngā mahi Māori.
