title: Designing with biobased composites: understanding digital material perception through semiotic attributes

authors: Thundathil, Manu

subjects: Product Design

abstract: Biobased composites, which are considered a sustainable alternative to plastics, are yet to create a significant influence on product design and manufacturing. A key reason for this is perceptual handicaps associated with biobased composites and this study was aimed at understanding the mechanisms behind biocomposite perception, in the context of digital visuals. This study of digital biocomposite visuals demonstrated that material perception is influenced by the visual characteristics of the material. Data analysis of the perceptual attributes of the materials pointed towards clear ‘clustering’ of the materials against these attributes. Analysis shows that visual features like fibres and surface appearance may impact aesthetic and functional evaluation and there is no effect on age, gender or polymer type. We also propose a reference framework to categorise biobased composites based on visual order.

title: Mammalian Pests in the Waikato Region

authors: Breedt, Brandon

subjects: pest

abstract: This project aimed to use camera traps to study the distribution of seven important mammalian pests across the three main vegetation types of the Waikato Region and to see if this method is a more informative alternative to other passive detection methods. For this study, the species of interest are the common brushtail possum (Trichosurus vulpecula), the European hedgehog (Erinaceus europaeus), ship rat (Rattus rattus), house mouse (Mus musculus), stoat (Mustela erminea), ferret (Mustela putorius), and weasel (Mustela nivalis).

The objectives of this study were to 1) calculate the distribution of each mammalian pest within the three main vegetation types of the Waikato Region 2) to determine site occupancy i.e. patchiness of species distribution within these habitats, and the probability of detection where they are present and 3) to evaluate whether the above parameters are influenced by the seasons and/or interactions between the species.

To meet these objectives, I measured five parameters related to site occupancy and activity levels for each species, and use the results to present an estimate of the proportion of the Waikato Region occupied by each species.

These analyses suggest that suggest that species distributions are very much dependent on habitat, but a large portion of all species was accounted for by pastoral areas. Even when species are not particularly abundant on pasture, it makes up more than half of the Waikato, and as such is potentially a source for reinvasions of controlled areas when not cleared in concert with the surrounding areas.

title: E kore e ngaro, he takere waka nui: Te mātauranga whakatere waka me ōna take nunui

authors: Tuaupiki, Jackie Whetumarama

abstract: E kapi ana te hautoru o te ao i te Moana nui a Kiwa. I ngā tau manomano ka huri, ka puea ake i Āhia ki te tonga mā rāwhiti, he iwi māia, he iwi mātau ki te hanga me te whakatere i ō rātou waka. Ka tupu ngātahi hoki i a rātou tētehi mātauranga whakatere i tarawhitia e rātou ngā tōpito katoa o te Moana nui a Kiwa. Koinei ngā tāngata tuatahi, nāna i kau ngā ara terenga waka onamata. Nō ngā tau maha i muri iho, ka whanake tēnei mātauranga me tō rātou hangarau waka, ā, ka tīmata ngā terenga whakawhiti roa e tau haeretia ana ngā moutere o Poronīhia, tatū mai ki Aotearoa. Engari ia, i roto i te wā, i tino waikauere ngā mahi whakatere waka, ā, i ētehi moutere o Poronīhia, i wairuhi kau, he mahara noa i mau i te kōrero tuku iho. Ko tātou tērā, te iwi Māori.

Otirā, i roto i ngā tau e whā tekau ka pahemo atu rā, kua whakawhāiti mai tētehi ohu ki te whakahaumanu i ngā mahi whakatere waka me tōna mātauranga. He waka hourua kua hangaia i Poronīhia, i te ātārangi tawhito hei amo i ngā whakamanawatanga o ngā iwi me ngā kaupapa whakarauora i ēnei mahi tūpuna. Ka tika te oha ki te hunga hāpai kura i takere nui ai, i haumi tūporo ai ki te whakahaumanu i te mātauranga whakatere waka. Nō reira, o ngā mahi rangatira kua tutuki i te rāngai waka i Aotearoa i ngā tau tata nei, ko tā tēnei rangahau, he kohura i ētehi o ngā take nunui me ngā kaupapa whakahirahira e puta mai ana i mua i te aroaro o te mātauranga whakatere waka me ōna kaumoana i ēnei rangi, ki tā te Māori titiro. Waihoki, ko te pānga o aua take nunui ki te ahurea Māori. Koinei te matū o tēnei tuhinga kairangi. He pūtoi whakaaro, he whakaemieminga kōrero ki te whakatakoto i ngā huatau o ngā puhi kai moana Māori e tākawe ana i tēnei wānanga.

Mātua rā, e kore e tukua kia riro anō ngā mahi whakatere waka i te nenewhatanga o te rā, tau ki te rua. Kua whakatupuria e te wā he kura kaumoana Māori, māna ngā take matua o tēnei tuhinga roa e whakatutuki ki tua i te pae kai ao.
