title: Rahui and marine construction: Potential for enhancement of taonga species

authors: Fox, Danielle

subjects: Maori

abstract: The aims of my study were to investigate whether marine reserves enhance intertidal species used by Māori in a traditional or contemporary sense, and whether artificial structures in the intertidal region (such as wharf and bridge pilings) provide suitable habitats for traditionally harvested species. Further, I investigated whether non-indigenous species were found in these habitats, which may affect traditionally used species.
The abundance of ataata (cat's eyes; Turbo smaragdus) and kina (sea urchin; Evechinus chloroticus) were quantified in three marine protected areas and nearby unprotected reference beaches. Results from Mann-Whitney U comparisons suggested that kina were significantly enhanced inside the two marine reserves with total protection. Kina are released from harvest pressure inside these reserves and possibly from the effects of predation and competition. In one reserve ataata abundance was significantly lower and no difference was found for ataata in the second reserve. This species is not as heavily harvested as kina and may even be negatively affected by trampling inside reserves. Both kina and ataata showed no response to a partially protected marine park. Abundance of both non-indigenous species was not sufficient enough to be sampled and statistically quantified at the marine reserve sites. Biotic resistance may restrict the proliferation of non-indigenous species in rocky intertidal marine reserves. 
Intertidal fauna were scraped from concrete and wooden structures and were compared with fauna inhabiting nearby natural rocky reefs. Multi-dimensional scaling and ANOSIM was used to explore trends in the community composition of different study sites, and to illustrate which habitat types are more associated with traditionally used and non-indigenous species. The main results conclude that diverse communities are associated with natural habitats whereas constructed structures have limited fauna. Of the traditionally used species, the native rock oyster (Saccostrea glomerata) was found in relatively equal frequencies on artificial habitats and rocky reefs, and the non-indigenous oyster (Crassostrea gigas) was predominantly recorded on artificial structures and rare on natural substrates. The construction of artificial structures around New Zealand's coastline may assist in the spread of non-indigenous species, to the detriment of species traditionally used by Māori.

title: The utterance, the body and the law: Seeking an approach to concretizing the sacredness of Maori language

authors: Mika, Carl Te Hira

subjects: Maori language

abstract: In what possible ways does the sacredness of a language have application in an everyday, concrete sense – in a contemporary context? If we want to discuss the sacredness of language, can we conceptualise such sacrality in anything other than an abstracted form? I will consider some places where a proposed sacredness of the Maori language might come to bear, and will particularly question its usage within the process of the law. My primary aim in this article is to conceive of ways, however hypothetical, by which the sacredness within Maori language might be removed from its current role of discursive entity and into the active life of the speaker. Thus Maori language, even in its colonized form, may once more take its own place within the spheres of the practical and the sacred at the same time.

title: Critical Sets of Full n-Latin Squares

authors: Cavenagh, Nicholas J.

subjects: Science & Technology

abstract: The full n-Latin square is the n × n array with symbols 1, 2,..., n in each cell. In a way that is analogous to critical sets of full designs, a critical set of the full n-Latin square can be used to find a defining set for any Latin square of order n. In this paper we study the size of the smallest critical set for a full n-Latin square, showing this to be somewhere between (n3 − 2n2 + 2n)/2 and (n − 1)3 + 1. In the case that each cell is either full or empty, we show the size of a critical set in the full n-Latin square is always equal to n3 − 2n2 − n.
