title: Microstructure and mechanical properties of large size as-cast Ti-43Al-9V-0.2Y (at.%) alloy ingot from brim to centre

authors: Kong, Fantao

subjects: Intermetallics

abstract: A Ti-43Al-9V-0.2Y (at.%) alloy ingot with the size of Ф160×400mm was prepared by vacuum arc remelting (VAR). The microstructure of the as-cast Ti-43Al-9V-0.2Y alloy was composed of B2/α₂/γ lamellar colonies and massive B2 and γ phases which were distributed along the boundaries of these lamellar colonies in the form of equiaxed grains. Based on the grain size variation along the radius direction of the ingot, the ingot could be divided into four ring regions from brim to centre. It has been understood that the grain size variation between these four regions was due to the interplay of the effects of the cooling rate and the yttrium content on solidified microstructures in these regions. Mechanical testing of the samples cut from these four regions showed that there existed a clear correlation between the yield strength and the average grain sizes of the four ring regions, which approximately conformed to a Hall-Petch relationship.

title: Teu le vā: Cultivating the space between: An investigation into Samoan-Palagi intimate partner relationships.

authors: Finnigan, Hannah Sarah

subjects: flourishing

abstract: This thesis investigates how Samoan-Palagi intimate partner relationships flourish. Key areas of investigation include important factors influencing participants’ relationships, what flourishing means to participants, how the flourishing of each partner is supported by the relationship, and how partners negotiate the vā fealoaloa’i (relational space) between them. A qualitative research design was used to examine the lived experiences of two Samoan-Palagi couples. The theoretical framework for this research was informed by the Uputāua Therapeutic Approach, fono fa’atalatalanoa (narrative dialogue) and positioning myself as a naive learner in the research. Data collection involved multiple interviews, first with both partners of each couple and then a follow-up interview with each individual. The information shared in these interviews is presented in two case studies. The findings of this research advocate for flourishing relationships as a process, and suggest that by looking after the relational space and constantly attending to the relationship, it may flourish and grow. The relational space does not refer to a single domain, but is holistic and addresses each partner in their totality. Flourishing, for participants, involves the development of interdependence by navigating a continuum of individual and collective needs, in order to support the relationship. This research provides insight into how vā fealoaloa’i (the relational space) and teu le vā (tending to/looking after this space) can operate in intimate partner relationships.

title: Ko au tēnei

authors: Temara, Pou

subjects: Tuhinga auaha

abstract: He puha tēnei, he momo rotarota. E kōrero ana tēnei puha mō te pepeha o Tūhoe, arā, ko Maungapōhatu te maunga, ko Waikare te awa ko Tamakaimoana te hapu, ko Taiturakina rāua ko Pōhokorua ngā tāngata, ko Tūhoe te iwi.

Kua roa tēnei pepeha e mau ana i ngā kākahu Māori o nehe, ā, nō ngā rautau ki muri te tawhito o te pepeha nei. Kua mate noa atu te hunga nā rātau i waihanga. Ko rātau e mōhio ana ki te horopaki i titoa ai ā rātau pepeha. Taka iho ki nāianei kāore anō kia rerekē ngā kupu o te pepeha.

Engari kua rerekē te ao me tōna tai, he whakatipuranga hou kua hua ake hai noho i te whenua. He rerekē ōnā whakaaro, he rerekē te ahurea. Kua roa e noho tahi ana ēnei whakatipuranga me ngā iwi huhua o te ao, he rauiwi te ahurea. Kua whakatōria hoki te whakaaro o aua ahurea maha ki te hinengaro o te Māori. Kua riro ngā whakaaro i te ao whānui koia nei kai te tohutohu i te whakaaro o te Māori o ēnei rā.

Me pēhea te whakauru atu i te whakaaro o mohoā nei ki te whakaaro o ukiuki, kia whai tikanga ai ki te ngākau o nāianei ki te pepeha o mua? Kua tawhito o rātau kākahu. E hia ngā kaupapa, ngā pakanga, ngā kaikiritanga, ngā mamae i roto i taua wā. Kua tae ki te wā hai whakamautanga mā ō nāianei Māori i ngā kākahu o ēnei rā ki ngā pepeha o mua, kia whai wāhi ai ki te ahurea me te whakaaro o ēnei rā.

Ehara i te mea me whakaae te iwi katoa ki ngā whakaaro kua tāpiritia ki te pepeha nei. Engari hai aha mā wai? Ko te rotarota he kupu nā te kaitito, he kupu motuhenga nō tōna ngākau, hai tohu i tāna titiro ki te ao, ā, kia uru atu ai ia ki te ao me ngā whakaaro o mua.
