title: New Zealand research on the economic impacts of immigration 2005-2010: Synthesis and research agenda

authors: Hodgson, Rob

subjects: immigration

abstract: This paper brings together the key research findings of some 20 projects conducted in New Zealand on the economic impacts of immigration from 2005 to 2010. Besides providing a synthesis of this research, knowledge gaps that could be addressed in future research are also identified. The report concludes that immigration has made a positive contribution to economic outcomes in New Zealand and that fears for negative economic impacts such as net fiscal costs, lower wages, and increasing unemployment find very little support in the available empirical evidence. Moreover, the economic integration of immigrants is broadly successful. Once migrants are in New Zealand for more than 10–15 years, their labour market outcomes are predominantly determined by the same success factors as those for the New Zealand born. Migration increases trade and tourism, both inbound and outbound. The net fiscal impact of immigration is positive. Findings on impacts on housing and on technological change are less conclusive. Simulations over a 15-year period with a CGE model suggest that even without additional technological change, additional immigration raises gross domestic product (GDP) per capita, albeit only modestly. Conversely, without net immigration, GDP per capita would be less. The CGE model simulations also suggest that changes in immigration policy and changes in the New Zealand economy over the last quarter century now yield greater economic benefits from immigration than in the past. Future research should focus on: the path of adjustment of the economy over time, following a change in the level of immigration; physical and human capital investment in the economy triggered by immigration; the economic consequences of greater diversity; and differences in impacts between temporary and long-term migration.

title: The metabolism of parts of seeds during early germination

authors: Collins, Desmond Michael

abstract: There have been few studies of the metabolism of germinating seeds during the first minutes and hours of imbibition. This is partly because most biochemical techniques are unsuitable for studying these biological systems. One technique that has been developed for studying such systems involves using tritiated water as a tracer. In this technique the biological material is placed in tritiated water for a known time and then extracted. The extracts are chromatographed on paper and the tritium labelled compounds are detected by scintillation radioautography. The technique has already been successfully applied to the study of intact seeds of two species of dicotyledons. In this present work the technique was used to study the metabolic development during the first six hours of imbibition of the different parts of seeds from four species: a monocotyledon (barley), two dicotyledons (Phaseolus vulgaris and castor oil), and a gymnosperm (Pinus radiata). The seeds of these species are representative of the majority of seeds in the plant world. The results show that performing experiments on excised parts of seeds provides additional information to that obtained from using intact seeds. The most important conclusion of this work is that the axes and embryos of all seeds develop the same basic metabolic pathways during the first hours of imbibition and that these pathways develop in a similar order. Amino acid metabolism begins during the first few minutes of imbibition, followed by the metabolism of Krebs cycle acids and, after two hours, sucrose metabolism. Ten different labelled compounds were identified and labelled groups of compounds described as lipids and sugar phosphates were also present. Detailed conclusions are made about the metabolism based on the tritium labelled compounds formed, together with any other relevant information available. A number of additional experiments, including ¹⁴C tracer experiments, were performed on parts of two of the seeds. These experiments enabled more definite conclusions to be made about the metabolism of sucrose and 4-aminobutyrate, two of the compounds labelled in the tritiated water experiments. Most and in some cases all the labelled compounds formed in the axes and embryos were also found in the storage organs. However, the rate of metabolic development of the storage organs was slower than that of their corresponding axes or embryos, and a comparison of water absorption to metabolism indicated that initially this may have been due to their slower water absorption. The metabolic development was not as uniform among the storage organs as it was among the embryos and axes. In particular, the barley endosperm appeared to have a much simpler metabolism than the castor oil endosperm and it was shown that its metabolism occurred entirely in the aleurone layer of cells on its surface. It is concluded that the metabolic development of seed storage organs depends more on their morphology and function than on their embryological origin.

title: Integrating mātauranga Māori into community resilience frameworks for the built environment

authors: Dunlop, Ezra

abstract: Efforts to improve community resilience have seen universal efforts to grow capabilities in disaster management for the built environment. Although comprehensive frameworks exist, the perspective used to derive these frameworks fails to address marginalised communities' vulnerabilities, including the Indigenous Māori people. Colonisation and socio-economic deprivation of Māori mean community response frameworks fail to reflect their values and specific needs when preparing and responding to natural disasters.
The nature of Māori culture and values presents an opportunity to reimagine the scope of community resilience for an inclusive framework. The Māori history has resilient practices weaved into the very fabric of their culture through the oral transmission of waiata, whakataukī, whakairo, and pūrākau. The practice of community resilience amongst ancient Māori was not consigned to singular events but is a holistic perspective bound to their manner of living. Sourcing and qualifying this information from people aligned and immersed in nature is the knowledge required to improve the frameworks to respond to natural disasters while expanding the literature on community resilience.
This study collaborated with Ngāti Toa to represent the Māori worldview using tikanga Māori and Kaupapa Māori methodology in an action-based participatory research approach. The research analyzed traditional Māori resilience through wānanga and korero kanohi-ki-te-kanohi and evaluated various mātauranga, tikanga, and kaupapa that relate to the resilient nature of Ngāti Toa. Modern Māori perspectives of community resilience were compared to this information using a realistic earthquake scenario in the Wellington region. This led to expanding community resilience to be more inclusive of Māori communities and informed measures to enhance their resilience and address their unique needs following a disaster.
This study found that the Ngāti Toa community employs traditional resilience practices dating back to their migration to Aotearoa from Hawaiki. These practices are community-led and grounded in unity, with resilience being viewed as a collective responsibility. The study identified various Te Ao Māori resilience principles by translating traditional resilience principles into corresponding Te Ao Māori principles. A response and recovery plan was developed for Ngāti Toa in response to a realistic earthquake scenario. This plan includes a vulnerability matrix and a community resilience calculator to inform Ngāti Toa of their vulnerability level and needs following a disaster.
The community resilience frameworks developed for the Wellington region in response to the 7.5 magnitude earthquake were found to be economically dependent and did not utilize the response capabilities and strengths of Ngāti Toa. The frameworks lacked proper representation from Ngāti Toa and failed to address the needs of the Māori community in Wellington, resulting in inequitable outcomes. To rectify this,

community resilience frameworks for Māori should adopt a principle-based approach that supports collaborative engagement and integrates Māori cultural values. Unity is a crucial strength underpinning Māori resilience. Technological mediums such as retrofitting Marae should be developed to enhance Māori response capabilities and harness the strengths of Te Ao Māori resilience.
