title: Reactions of isonitriles with [Fe₃(CO)₁₂] and [Ru₃(CO)₁₂] monitored by electrospray mass spectrometry: structural characterisation of [Fe₃(CO)₁₀(CNPh)₂] and [Ru₄(CO)₁₁(μ₃-η²-CNPh)₂(CNPh)]

authors: Decker, Corry

subjects: iron carbonyl

abstract: The reactions of [Fe₃(CO)₁₂] or [Ru₃(CO) ₁₂] with RNC (R=Ph, C₆H₄OMe-p or CH₂SO₂C₆H₄Me-p) have been investigated using electrospray mass spectrometry. Species arising from substitution of up to six ligands were detected for [Fe₃(CO)₁₂], but the higher-substituted compounds were too unstable to be isolated. The crystal structure of [Fe₃(CO)₁₀(CNPh)₂] was determined at 150 and 298 K to show that both isonitrile ligands were trans to each other on the same Fe atom. For [Ru₃(CO)₁₂] substitution of up to three COs was found, together with the formation of higher-nuclearity clusters. [Ru₄(CO)₁₁(CNPh)₃] was structurally characterised and has a spiked-triangular Ru₄ core with two of the CNPh ligands coordinated in an unusual μ₃-η² mode.
The substitution reactions of [M₃(CO)₁₂] by RNC have been investigated by electrospray mass spectrometry showing up to six COs can be replaced. [Fe₃(CO)₁₀(CNPh)₂] has both PhNC axially on the same Fe atom, and [Ru₄(CO)₁₁(μ₃-η²-CNPh)₂(CNPh)] has a spiked-triangular cluster core with two PhNC ligands in an unusual coordination mode.

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: What is Māori typography?

authors: Kennedy, Nikki Eileen

subjects: Māori Design

abstract: Te Reo Māori was traditionally an oral language similar to many indigenous cultures. Writing systems were not familiar to Māori until 1769 where Māori were introduced to the written language by Pākehā. Early Māori writing can be found printed, carved and painted in a number of different parts of Māori society. These myriad texts were strongly influenced and inspired by Pākehā biblical texts and newspapers. The influence of Pākehā texts meant that overtime the written language of Te Reo Māori had a Pākehā visual identity.

To date, there is minimal research about the history and visual identity of Māori typography. The lack of research and resources about Māori typography confirms how underdeveloped Māori typography is and highlights the potential for research and development in this space.

This thesis aims to explore Māori typography. In particular, this thesis will provide an understanding of how Māori typography has evolved, addressing the perceptions of Māori text features and advice on design guidance of Māori typography.

Two studies within this thesis involved analysing the text-based features in 21 Māori newspapers dated from 1842-1935. Māori newspapers are a valuable resource that captured moments in history and also early displays of Māori text. The second study involved interviews with 50 participants — Māori and non-Māori, from a range of different backgrounds — who provided their understandings and perceptions surrounding the features of Māori text.

The results from these studies have shown that the serif typeface classification was commonly used in early print such as Māori newspapers. Serif lettering also reminded participants in our studies of early Māori texts such as old text books and newspapers. This appears to be the reason as to why, a strong theme of serifs and the style of Didone typefaces have been used throughout Māori typography and by default are recognised features of Māori typefaces today.

Having analysed Māori newspapers, an unexpected finding appeared in the 1908 Te Pipiwharauroa newspaper. Two unique letter characters were found that was revolution for Te Reo Māori text of the time. This oddity combined the ‘ng’ letters into one letter character and the ‘wh’ letters into one letter character also. The aim in combining the two letters together was to emphasise the one sound that the ‘ng’ and the ‘wh’ make to avoid confusion in the pronunciation of Māori words. The results showed that these two letter characters appeared from 1908 through to 1912. There is no evidence of these characters appearing after 1912 and also appearing in other newspapers. The two characters were a rare appearance of its time.

As a result of this research it is clear that the visual identity of Te Reo Māori remains unclear and was highly influenced by serif lettering. This thesis highlights the need for more research about Māori typography and design guidance for developing appropriate Māori typefaces that are influenced and inspired by Maori culture.
