title: Rotational molding cycle time reduction using a combination of physical techniques

authors: Abdullah, M.Z.

subjects: rotational molding

abstract: Rotational molding is a process used to manufacture hollow plastic products, and has been heralded as a molding method with great potential. Reduction of cycle times is an important issue for the rotational molding industry, addressing a significant disadvantage of the process. Previous attempts to reduce cycle times have addressed surface enhanced molds, internal pressure, internal cooling, water spray cooling, and higher oven air flow rates within the existing process. This article explores the potential benefits of these cycle time reduction techniques, and combinations of them. Recommendations on a best practice combination are made, based on experimental observations and resulting product quality. Applying the proposed molding conditions (i.e., a combination of surface-enhanced molds, higher oven flow rates, internal mold pressure, and water spray cooling), cycle time reductions of up to 70% were achieved. Such savings are very significant, inviting the rotomolding community to incorporate these techniques efficiently in an industrial setting.

title: The future of surrogacy in New Zealand – Beyond the adoption model

authors: van Zyl, Liezl

abstract: Surrogacy in New Zealand is treated as a form of adoption. ACART (2014) proposes that the Health Minister consider compensating women who act as surrogate mothers. We think this is a step in the right direction, but until the adoption model is abandoned surrogacy will not be a safe practice for New Zealanders. ACART’s consultation document does not address the issue of legal parenthood, but it is one that is intimately linked to the issue of compensation to surrogates because the Adoption Act (Section 25) prohibits payments in consideration of adoption. If, as we will argue below, surrogates deserve to be compensated for their labour, it is imperative that we acknowledge that the adoption framework is inappropriate in surrogacy.

title: Caught in the cross-fire: the realities of being Māori at a bicultural law school

authors: Papuni-Ball, Makere

abstract: This thesis examines the first Waikato Māori Law Graduates’ experiences at law school and our employment choices. It has been written as a result of a research project which was conducted in 1994. The paper begins with establishing the importance of other Māori the guidelines on this project. In this discussion, my role as the researcher is explained together with how the original research project impacted upon this thesis.

Waikato School of Law was established in an era of socio-political changes in our society. Te Matahauariki Report supported its establishment based upon proven demand for law graduates. It also envisaged the School as being a meeting place for all who attended, an institution which might encourage relationships between Māori and Pakeha societies. The Council of Legal Education supported the need to have at least one law school which would not reflect the traditional legal education system and acknowledged the need to incorporate a Māori perspective. Tainui as tangata whenua hoped the school would provide opportunities for Māori students, including Māori in the curriculum and assist in promoting research ensuring the recognition of Māori lore/law.

Amongst this backdrop, the most important reason why we came to law school was because of our whānau expectations. It is the accountability and responsibility we have as Māori to our whānau and the wider Māori community that is a major theme throughout this thesis. As students we were expected to utilise our skills to benefit our wider Māori networks.

We had expected that the School would provide us with a legal education which would be enriched in Māori kaupapa. Our experiences tell another story. Instead of being educated in Māori tikanga and the true discourse of the law as a tool of oppression, we were exposed to continual suppression of our cultural heritage. In class we had become the teachers of the Māori content.

The School, although admiral in its aims, was not prepared in structure, staff or mental processes for biculturalism. The consequences for the Māori students who were exposed to this structure was devastating. Our experiences of being discriminated against and made to justify our Māori perspective against the backdrop of the dominant Pakeha legal culture have affected our perceptions of the law. The myths of one law for all and the neutrality of the justice system have resulted in our choosing to work in jobs that will continue to benefit Māori.

It is suggested that our legal education has influenced our choices to work in areas which focus on benefiting the Māori community. In those monocultural work areas which have few Māori practising, this is because such places repel those of us who know that such work places perpetuate the dominant Pakeha culture. Māori struggle against the oppressive presence of the dominant culture.

This thesis calls upon my own experiences and the experiences of my fellow Māori law graduates. It is a starting point for other Māori to write about their experiences and to reassert Māori rangatiratanga not only in law school, but in the wider community.
