title: Design and operation methods for better performing heat recovery loops

authors: Walmsley, Michael R.W.

abstract: Inter-plant integration via a heat recovery loop (HRL) is an economic method for increasing total site process energy efficiency of semi-continuous processes. Results show that both the constant storage temperature approach and variable storage temperature approach have merit. Depending on the mix of source and sink streams attached, it may be advantageous to change the operation of an existing HRL from a constant temperature storage to a variable temperature storage. To realise the full benefits of this change in operation, a redistribution of the existing heat exchanger area may be needed.

title: Multiple senses of community among older Chinese migrants to New Zealand

authors: Li, Wendy Wen

subjects: ageing in place

abstract: Existing literature suggests that successful ageing is linked to a sense of community (SOC) that is developed through shared daily practices. For migrant groups, SOC can extend across home and receiving countries. In order to understand the issue of successful ageing in place and multiple SOCs among older Chinese migrants, this paper investigated 32 older Chinese migrants' narratives of developing a SOC in their local and home communities. Findings suggest that a SOC can be viewed as constructed through practices such as neighbouring and supportive interactions within local contexts as well as engagement with the home country via new media. The findings provide insights into everyday practices central to the cultivation of a SOC among the participants whose engagements span the cultural spaces of China and New Zealand. For example, the use of media contributes to the participants' SOCs both in China and New Zealand. As a result, they live in a transnational community that can be understood as an ‘imagined’ community where the participants engage with significant, although absent, Chinese others. Living between China and New Zealand, between homes and between languages, the participants create identity ‘inbetweenness’ that is constructed at the intersection of interdependent, compatible and mutually reinforcing communities and spaces. The findings therefore extend conventional understandings of ageing migrant experiences that assume successful ageing and community participation occur in one locale to an understanding of multiple SOCs within the context of transnationalism.

title: Intellectual Property, Mātauranga Māori

authors: Sterling, Rogena

abstract: This literature review has been conducted to consider the various national legislation and international agreements that comprise New Zealand’s Intellectual Property Rights (IP) regime. It will evaluate if and how such legislation and agreements protect and enable Māori IP rights and interests with respect to Māori data, genomic data and mātauranga Māori. The review also identifies some mechanisms that might also enhance Māori control of these types of data. The Westminster approach of legislation in New Zealand and its approach to IP protection based on Copyrights, Patents and Trade Marks are juxtaposed against traditional Maori approaches of communally held ancestral knowledge (mātauranga) passed down through generations (whanaungatanga) based on guardianship and protection (kaitiakitanga) and the self-determination of use of such knowledge (rangatiratanga). Attempting to align tikanga concepts to the Westmionster model of law is challenging as the two share completely different notions of ownership and responsibility. Expectations of protection, to prevent misappropriation and commercialisation by non- Māori of mātauranga Māori and Māori data, extend beyond the parameters of existing IP law, creates a similar disjunct. Genomic Research generates data, some of which can be protected by IP, however researchers working with genetic/genomic data from taonga species have often failed to acknowledge the non-IP interests of Maori. As a result, Maori have taken it upon themselves to advocate for their rights to data through Māori data sovereignty discourse as well as create guidelines for culturally appropriate genomic research with explicit references to data security and management (e.g. Te Mata Ira, Te Nohonga Kaitiaki). Other extra-legal options, such as Biocultural Labelling to alert users where particular data has Māori rights and/or interests, are emerging to maintain create durable provenance data and connect next users of data with the responsible Indigenous communities. Though the intellectual property regime in New Zealand may provide some protections, there are still significant areas where the legal system does not provide sufficient protections for Māori data, taonga species and mātauranga. The UN Declaration on the Rights of Indigenous Peoples provides a framework of international support for Indigenous rights, but local government and other home-grown mechanisms are important to enable Māori governance of data. Local approaches Māori Data Sovereignty and Māori Data Governance afford Maori the opportunity to be directly involved as kaitiaki of their mātauranga and assert rangatiratanga over data and its use.
