title: Revitalizing Te Ika-a-Maui: Māori migration and the nation

authors: Mahuika, Nepia

subjects: Māori

abstract: Maui-Tikitiki-A-Taranga is more than simply a ‘mythic’ hero. For many he is a prominent figure in a long family line. The whakapapa that binds Māori to our tupuna is significant to the present and future, and carries with it the ‘ultimate expression’ of who we are. Maui has been described as ‘the most important culture hero in Māori mythology’, whose exploits and archetype provide precedents that Māori respond to in the present. The status of Maui within my own tribal boundaries is clear: ‘In accordance with the traditions and tikanga of Ngati Porou, we as People of this Land have been here since the beginning of time, or more aptly in the context of Aotearoa, since Maui fished up Te Ika-a-Maui (North Island). Maui-Tikitiki-a-Taranga is attributed with fishing up the North Island, raising it out of the depths of the sea, for successive generations of Māori to populate and cultivate.’ Maui’s waka, as Ngāti Porou uphold, is Nukutaimemeha, believed to be ‘cradled’ upon our ancestral mountain Hikurangi. However, there are other stories that recognize the waka as the South Island, with Stewart Island its anchor. These variations aside, the history remains a well-rehearsed one throughout the Māori world and in other parts of Polynesia.

title: Exploring inequity in access to medications for Type 2 Diabetes in primary care in the Waikato region: Final report

authors: Lawrenson, Ross

abstract: Type 2 diabetes (T2D) is a growing health issue in New Zealand (NZ) that disproportionately affects twice as many Māori as non-Māori and an increasing number of younger people. T2D is associated with a range of microvascular and macrovascular complications, chronic kidney disease and cardiovascular disease (CVD), the latter being the greatest cause of morbidity and mortality in this patient group. However, complications are reduced in patients that have improved glycaemic control. To achieve optimal outcomes and reduce the chance of diabetes-related complications, patients should aim to have their glycated haemoglobin (HbA1c) measurement less than 53 mmol/mol if possible.

Diabetes is primarily managed in primary care, and a number of recent publications suggest that there is considerable inequity in the management of diabetes in New Zealand, particularly for Māori. In an earlier piece of work we have shown that Maori are significantly less likely than non-Maori to be prescribed metformin, but that once prescribed it they are equally likely to have the medication dispensed. This suggests that there may be issues that can be addressed within primary care that are influencing the use of diabetes medications.
Thus, the aim of this small piece of work was to characterise diabetes medication use in a Waikato primary care population, and to report on medication adherence and association with HbA1c levels.

title: Polylactide composites reinforced with pre-impregnated natural fibre and continuous cellulose yarns for 3D printing applications

authors: Priya Muthe, Lakshmi

subjects: additive manufacturing

abstract: Achieving high-performance 3D printing composite filaments requires addressing challenges related to fibre wetting and uniform fibre/polymer distribution. This study evaluates the effectiveness of solution (solvent-based) and emulsion (water-based) impregnation techniques to enhance fibre wetting in bleached flax yarns by polylactide (PLA). For the first time, continuous viscose yarn composites were also produced using both impregnation techniques. All the composites were carefully characterised throughout each stage of production. Initially, single yarns were impregnated and consolidated to optimise formulations and processing parameters. Solution impregnation resulted in the highest tensile strength (356 MPa) for PLA/bleached flax filaments, while emulsion impregnation yielded the highest tensile strength for PLA/viscose filaments (255 MPa) due to better fibre wetting and fibre distribution. Impregnated single yarns were then combined, with additional polymer added to produce filaments compatible with standard material extrusion 3D printers. Despite a reduction in the mechanical performance of the 3D-printed composites due to additional polymer impregnation, relatively high tensile and bending strengths were achieved, and the Charpy impact strength (&gt;127 kJ/m2) for the viscose-based composite exceeded the reported values for bio-derived fibre reinforced composites. The robust mechanical performance of these filaments offers new opportunities for the large-scale additive manufacturing of structural components from bio-derived and renewable resources.
