title: A synchronised Direct Digital Synthesiser

authors: Payne, Andrew D.

subjects: DDS

abstract: We describe a Direct Digital Synthesiser (DDS) which provides three frequency-locked synchronised outputs to generate frequencies from DC to 160 MHz. Primarily designed for use in a heterodyning range imaging system, the flexibility of the design allows its use in a number of other applications which require any number of stable, synchronised high frequency outputs. Frequency tuning of 32 bit length provides 0.1 Hz resolution when operating at the maximum clock rate of 400 MSPS, while 14 bit phase tuning provides 0.4 mrad resolution. The DDS technique provides very high relative accuracy between outputs, while the onboard oscillator’s stability of ±1 ppm adds absolute accuracy to the design.

title: Integrating product design and supply chain management for a circular economy

authors: Burke, Hayden

subjects: Circular Economy

abstract: Circular economy (CE) provides an alternative development model to the dominant take-make-dispose linear approach, and thus a new vision for solving sustainability challenges. Firms need to operationalise CE in their supply chain operations, starting from circular product design as the foundational step. The purpose of this paper is to investigate how to integrate product design and supply chain management (SCM) decisions for a CE transition. A thematic analysis was conducted on data collected from 15 semi-structured interviews in New Zealand. Four propositions were established based on the identified themes, namely, end-of-life thinking in product design, circular SCM, business model innovation,
and sustainable organisational values. The study results provide a novel insight into the integration of product design and SCM for a CE transition. The operational framework developed provides guidance to product designers, managers, and researchers to advance the CE cause at the supply chain level.

title: Maori participation in higher education: Tainui graduates from the University of Waikato, 1992 to 1997

authors: Tiakiwai, Sarah-Jane

abstract: This thesis is an examination of what factors contribute to the success of Maori who participate in higher education. The thesis is informed by the experiences of nine Tainui tribal members who received scholarships from the Tainui Maori Trust Board and who graduated from the University of Waikato between 1992 and 1997. 

The thesis addresses two questions: what factors contributed to the success of Tainui graduates at the University of Waikato? What effect did programmes, policies and initiatives offered by the University of Waikato and the Tainui Maori Trust Board have on the academic success of Tainui graduates at the University of Waikato? 

There are three main components to the thesis: a brief history of the University of Waikato and an examination of three documents (University of Waikato Charter 1991; Paetawhiti, the strategic plan 1993; Academic Audit Unit report 1997) and how they pertain to Maori; a history of the Tainui Maori Trust Board and an examination of the Tainui Education Strategy (1986, 1991), its review (1993) and scholarship programmes; and a study and analysis of the experiences of nine Tainui graduates from the University of Waikato. 

Argued from an eclectic theoretical and methodological position, drawing from indigenous and western theories and research practices that emphasise a kaupapa Maori and tribal approach, the thesis identifies multiple factors that have contributed to the success of the Tainui graduates. These factors include family and parental support, mentoring, the role of finances, institutional support, and identity. 

The thesis finds through examination of the documents, that the policies, initiatives and programmes of the Tainui Maori Trust Board and the University of Waikato have ambiguous and at times conflicting aims and objectives in regard to Maori participation and graduation from higher education. The thesis also finds that the experiences of the graduates reveal that neither the Tainui Maori Trust Board nor policies relating to Maori at the University of Waikato played significant roles in the success of the Tainui graduates. Rather, the thesis finds that the success of the graduates is largely borne by their own efforts, which reflect western notions of success, but which also reinforce their identity as Maori, and as Tainui tribal members. 

The thesis suggests that both the Tainui Maori Trust Board and the University of Waikato review their relationships with their tribal and Maori members (respectively), and recommendations are made to help develop a greater awareness of the contribution that both organisations can make to the success of Maori university students.
