title: Te Mātaiaho as curricular justice?

authors: Shafer, Derek

abstract: Te Mātaiaho produces a version of curricular justice which aims to give effect to Te Tiriti and address long-standing inequities in education in Aotearoa New Zealand. We examine Te Mātaiaho’s vision for subject English and its construction of students’ identities as fundamental to a curriculum that advances both bicultural nationhood and just outcomes for all students. We draw on Raewyn Connell’s (2010) model of curricular justice, and Nancy Fraser's (2017) notion of progressive neoliberalism to explore the opportunities and implications for subject English within Te Mātaiaho's vision. How might these frameworks for justice help to critique the development of educational policy and support the implementation of Te Mātaiaho's vision for biculturalnationhood and just outcomes for all students.

title: Ahumoana tawhito (ancient aquaculture): The translocation of  toheroa (Paphies ventricosa) and other marine species by Māori

authors: Taikato, Vanessa Rona

subjects: Mātauranga

abstract: Throughout time, humans have cultivated and translocated plants and animals. Ancient mariculture (the cultivation of marine species) often leaves little trace of human agency. Consequently, the extent to which mariculture was used in the distant past largely remains a mystery. In Aotearoa (New Zealand), Māori have a long history of translocating and cultivating terrestrial and freshwater species. Increasingly, it is becoming apparent that the translocation of marine species is a resource management tool that has been utilized by Māori for hundreds of years. Research into the population genetic structure of a large surf clam endemic to Aotearoa, the toheroa (Paphies ventricosa), has led to the hypothesis that Māori have undertaken long-distance transport and translocation of this shellfish during the earlier phases of Māori occupation within Aotearoa. Specifically, this “translocation hypothesis” suggests that Māori successfully transported toheroa from the West Coast of Te ika-a-Māui (the North Island) to the South Coast of Te Waipounamu (the South Island) thereby explaining the unique and disjunct distribution pattern of this taonga (treasured) species. This thesis weaves together knowledge from multiple disciplines to test the toheroa translocation hypothesis, explore technologies used by Māori and reclaim traditional knowledge regarding resource management. 

An examination of archaeological databases revealed a record that was not consistent with toheroa being endemic to Murihiku (southern South Island). On the west coast of Te Ika-a-Māui, 968 midden records were identified of which 40% either contained or consisted entirely of toheroa. In contrast, along the South Coast of Murihiku (Southland, Te Waipounamu), 122 midden records were examined, of which only 6.5% contained toheroa. Toheroa were not a major component of any of these middens. Toheroa were also absent from a natural shell deposit within Murihiku that pre-dates human arrival to Aotearoa. The general absences of toheroa in all but a few southern middens lends itself to the notion that toheroa did not occur there naturally, but were introduced by Māori at a later date. 

An examination of anthropological, historical and traditional knowledge was conducted to explore the human elements of toheroa translocation. Specifically, I wanted to better understand the reasons why early-Māori might have wanted to translocate toheroa, as well as the capacity and opportunities they would have had to undertake such long-distance transport of live bivalves. The movement of iwi from the north to the south is a concept steeped in kōrero tuku iho (oral history) and is referred to many times in ethnohistorical and contemporary literature. This included the very first movements of Polynesian explorers north to south, as well as multiple accounts of expeditions and southward migrations by Māori originating from the north. Toheroa were an important resource for the earliest occupants of northern regions in Aotearoa and this is evident in the prominence of toheroa in northern Māori culture. Interestingly, while they are a taonga of southern Māori today, toheroa are conspicuously absent in the narratives, whakataukī (proverbs) and whakapapa (genealogy) of Murihiku (Southland). This could be explained by a later introduction of toheroa to the area, leading to less time and opportunity of the resource to shape southern Māori identity. While toheroa may not have been endemic to the south, there was ample opportunity for them to be relocated, either through trade, or as part of a southward migration. Archaeological records of industrial stone, such as obsidian, provide evidence for trade between northern and southern Māori as early as the 14th century. It is clear that people who had come from or were closely connected to northern Māori have occupied the southern most areas of Aotearoa, in the earliest phases of the prehistoric sequence. 
While it is apparent that the opportunity for shellfish translocation existed, the suitability of toheroa for relocation was unknown. This would depend on their ability to cope with and combat stressors (such as hypoxia, bacterial proliferation, starvation and desiccation) associated with such a journey. Respiration rates, morphometric indices, behavioural responses and physiological responses to these stressors were measured in a series of in situ experiments. Toheroa displayed an overall physiological robustness to lack of oxygen and food and, when held in seawater and treated with antibiotics, toheroa were able to switch to anaerobiosis and survive for extended periods of time (more than two weeks). The primary causes of health deterioration were found to be bacterial proliferation (of particular prevalence when held in anoxic water) and desiccation. These are risks that could easily have been mitigated during a translocation journey.

The pōhā, a natural kelp bag fashioned from the large brown alga Durvillaea spp., is a southern Māori technology said to have been used in the translocation and re-seeding of toheroa and other shellfish species, prehistorically. An important first step in understanding this technology was to review the traditional knowledge associated with pōhā and of rimurapa (southern Bull Kelp) from which pōhā are constructed. The literature contained a variety of information covering prehistoric practices to contemporary management of this natural resource as well as details of its wide and varied uses. Interestingly, contemporary use of pōhā and rimurapa has included translocation and restoration of seagrass in Te Waipounamu. 

While there are many historical references to pōhā being used for translocating shellfish, the details of exactly how they were used are missing, both in the literature and in the memories of traditional practitioners of pōhā with whom I have been lucky enough to speak with. Consequently, the final component of this thesis explored the biochemical and bacterial implications of holding live toheroa in pōhā. I found that the photosynthetic blades of the algae were able to replenish dissolved oxygen consumed by the toheroa during respiration. Furthermore, it was clear that the microbiome associated with pōhā, or the secondary metabolites released by pōhā, influenced the bacterial community to which toheroa were exposed when held within the algal bags. From these experiments, it appears unlikely that pōhā were used in the manner employed in this experiment (filled with seawater and left to stagnate) as this resulted in the rapid deterioration of the pōhā bags. However, the biochemical and bacterial results that were found, have direct implications for the functionality of pōhā and the toheroa held within. While possibly not the main vessel in which toheroa were translocated, kōrero tuku iho about the use of pōhā in shellfish re-seeding, suggest that raw pōhā may have been the last link in the chain of shellfish translocation by providing protection while acclimating to a new area. 

The research I have undertaken for this thesis is novel and it contributes to our growing understanding of indigenous resource management in Aotearoa. While I have not been able to determine definitively whether toheroa in the south are solely a consequence of Māori translocation, the evidence presented here is consistent with that hypothesis. The experiments undertaken here are the first of their kind for toheroa, and they highlight how the complex nature of surf clam physiology and behaviour would play into their cultivation, either in ancient or contemporary contexts. This thesis reclaims traditional knowledge regarding the management of two taonga species (toheroa and rimurapa) and highlights several possible avenues for future research. Furthermore, this research demonstrates how academic knowledge and indigenous knowledge can be interwoven, to attempt to unravel the mysteries of the past and to pave the way for the future.

title: Typographic emphasis of headings: Methods of typographic emphasis to assist with search of unfamiliar and familiar text

authors: Timpany, Claire

subjects: Typography

abstract: Readers use headings to understand the structure and content of a text, and to locate information. Readers understand the structure of a text by building an understanding of the structure of the content through developing relationships between the sections of content. Headings assist readers with both their comprehension of text as well as assisting them with recall of the content. Headings provide signals to readers to aid navigation of a document by indicating the structure of topics. This helps readers to locate information both through signalling the content of text that may be unfamiliar or providing markers to assist with the recall of the location of information in a familiar text. 
The importance of headings is known; however, little research exists to indicate how these important organisational features of text should be presented visually. This research was undertaken to fill this gap in our understanding of how headings can assist readers. Five studies were carried out to investigate which heading emphasis methods are most easily identified within a passage of text and which of these methods best assist readers with searching text. 
An initial survey of current practice for emphasising headings revealed that there are six main methods for emphasising headings and these are often used in combination with each other to create stronger emphasis. It was also revealed that the presentation of headings in the same publication across print and digital formats is often inconsistent. This survey was used to help inform which heading emphasis methods were used in the paired comparison studies to test for ease of identification. 
Three paired comparison studies were then undertaken to establish which methods of typographic emphasis are most easily identified within a passage of text. These studies compared seven individual typographic emphasis methods with each other in print and on screen then compared five combinations of typographic emphasis methods in print and on screen. These studies found that emphasis methods with the greatest visual weight were the most easily identified. 
The most easily identifiable heading emphasis methods were then evaluated in search tasks to evaluate which of the four heading styles provided the most assistance when searching for answers in a screen-based text. This research showed that when headings are emphasised using styles that combine two heading emphasis methods they are easier to distinguish from the body copy surrounding them. These more easily identifiable headings are more useful to readers when they are searching for information in a text, both when the text is unfamiliar and when it is familiar. 
When bold is combined with either an increase in size or a sans serif typeface to create a heading, readers are able to more quickly and accurately find information within a document, whether that text is unfamiliar or familiar.
