title: The manufacture and mechanical properties of aligned long harakeke fibre reinforced epoxy composites

authors: Le, Tan Minh

subjects: compression moulding

abstract: Aligned long harakeke fibre reinforced epoxy composites were prepared using hand lay-up followed by compression moulding. Densities of harakeke fibre and epoxy resin were determined for the purpose of composite design. The evenness of composites fabricated by two different size moulds was compared. It was found that more even composites were produced when using a small mould than a big mould. In this work, the dependence of tensile and flexural properties of harakeke/epoxy composites on fibre content was also investigated. The results showed that the addition of fibre enhanced tensile properties of epoxy. The tensile strength and Young’s modulus increased with the volume fraction of harakeke fibre. The flexural strength and flexural modulus increased as the fibre volume fraction increased up to 0.4. Further addition of fibre did not result in an improvement of composite flexural properties.

title: Exploring the duality of harm: Emotion regulation and the functions of non-suicidal self injury and outward-directed injury in young people in Aotearoa

authors: Morrison, Tobey

subjects: ecological momentary assessment

abstract: Understanding why young people engage in self-injurious behaviours is crucial for improving their well-being outcomes. While Non-Suicidal Self-Injury (NSSI) has been explored to some extent in New Zealand, research on Outward-Directed Injurious Behaviour (ODI) remains limited both within New Zealand and internationally. Although traditionally considered distinct, emerging research suggests that NSSI and ODI may share more commonalities than previously recognised, particularly regarding their role in emotion regulation. This study used Ecological Momentary Assessment (EMA) to examine the functions and emotion antecedents of NSSI and ODI among 16–30-year-olds in New Zealand. Eleven participants provided EMA data, and seven of these also participated in interviews, offering deeper insights. Findings reveal key similarities between NSSI and ODI as coping mechanisms for managing distress. NSSI was primarily used to reduce anxiety, while ODI was used to alleviate frustration. 'Neutral' emotions were the most common precursor for NSSI, while 'anger' was the main trigger for ODI. Interview material revealed that participants often felt tired, overwhelmed, anxious, or bored when selecting 'neutral,' as these emotions weren't available as response options. Feelings of shame led to a shift from urges to engage in either behaviour to NSSI, while ODI was closely associated with anger in similar situations. Despite differences in how these behaviours are expressed, both serve to regulate negative emotions, highlighting the need to consider their shared functions in therapeutic and research contexts. This is especially important for ODI, which has traditionally been viewed as a delinquent behaviour, rather than as a coping strategy.

title: Reclaiming the Māori language for future generations: Flax root perspectives. Tīkina te mana o te reo Māori: Te pūtaketanga o te pā harakeke

authors: Peters, Murray Hamaka

subjects: te reo Māori

abstract: Using a combination of semi-structured interviews, focus group discussion and questionnaires (designed to elicit as many comments as possible), this thesis explores, through their own voices, the attitudes and practices of a group of people, mainly Māori but including a few Pākehā (non-Māori) who are attempting to reclaim te reo Māori (the Māori language), for themselves, their families and, above all, their children and grandchildren. Many of them were brought up in a context in which one or more parents, caregivers or relatives spoke te reo Māori fluently but few were given the opportunity to acquire the language naturally in infancy, generally because of a desire to protect them from the discrimination suffered by their elders. Those who were brought up to speak te reo Māori often suffered from language attrition at a time when the English language began to feature prominently in their lives. A few have attended kōhanga reo and kura kaupapa Māori. Many have attended courses in the Māori language and culture, often at considerable personal cost. Some have achieved their dream of becoming fluent speakers of the language; some have suffered frustration and disappointment. Whatever their own experiences, almost all of them want their children and grandchildren to be fluent speakers of the language, believing that this will give them confidence and a genuine sense of identity and belonging. Although the majority are committed to using te reo Māori as much as possible at home, especially when speaking to their children and grandchildren, most experience difficulties in doing so. These difficulties relate, in general, to their own lack of confidence and/or limited competence in the language, the fact that some of their friends and/or members of their immediate or extended family are monolingual in English, and resistance from some of the children, particularly as they grow older and are increasingly influenced by the dominant language and culture. Among those involved in this research project, there was widespread awareness of the importance of inter-generational transmission of te reo Māori and evidence of considerable commitment to learning the language and/or improving their existing competence in it. However, although the attempts of these adults to use te reo Māori in the home are clearly of considerable importance, they often, where they lacked a high level of oral proficiency, met with confusion, frustration, tension and resistance as their children grew older. This, combined with the fact that there are currently so few domains in society at large in which the language can be used naturally, has led many of them to develop strategies aimed at ensuring that their children and grandchildren, as they grow towards adulthood (a) appreciate the sacrifices made by so many in order to give them the opportunity to learn the language and the responsibilities associated with these sacrifices, (b) are recognised and rewarded for their linguistic achievements, and (c) are encouraged and assisted to involve themselves in contexts where they can use the language. This includes encouraging them to become involved in kapa haka and other culturally significant activities in which the language plays a prominent part, promoting as much engagement as possible with friends and whānau who have a high level of proficiency in the language (including involving them and their friends in marae-based activities), and inviting into their homes people who are fluent speakers (which sometimes involves a conscious effort on the part of the adults to cement friendships with fluent speakers and to encourage them to interact with their children). These are things which all parents and caregivers can do, irrespective of their own language competence. 

In doing these things, those who currently feel that they have little to offer in relation to the revitalization of the language can experience a genuine sense of involvement and empowerment. Accepting that there are currently many parents and caregivers who cannot realistically become involved in genuine inter-generational transmission of the language in the home does not mean accepting that they have nothing to offer. 

Mā te kōwhiringa o ngā uiuitanga hangā ngāwari, te whiriwhiri ā rōpū kanohi, me te puka patapātai (hei tōngia mai ngā kōrero whānui kē atu o tēnā, o tēnā), ka whakatewhatewha te tuhinga nei i ngā waiaro me ngā ritenga o tētehi rōpū e ngana ana ki te haumanu i te reo Māori hei taonga mō rātou ko ō rātou whānau, ā, mō ā rātou tamariki, mokopuna hoki. Te nuinga o te hunga nei he Māori; he tokoiti anō he Pākehā. He tokomaha o rātou i tipu ake i roto i te horopaki o te reo Māori, arā, kotahi neke atu o ō rātou mātua rānei, kaitiaki rānei, whanaunga rānei he matatau ki te reo Māori. Ahakoa rā, kāore te nuinga i whāngaihia ki te reo i ā rātou e pēpi ana, kei whakapai kanohitia pērā i ō rātou tūpuna. Ko rātou te hunga i tipu reo Māori mai, ka memeha haere tō rātou reo nō te tino putanga ake o te reo Pākehā ki ō rātou ao. He tokoiti o tēnei rōpu i kuraina ki te kōhanga reo me te kura kaupapa Māori; he tokomaha anō i whai wāhi ki ngā akoranga reo Māori me ōna tikanga, hāunga rā te nui o te nama. Ko ētehi, kua ea ngā wawata, kua matatau ki te reo; ko ētehi atu anō, kua pāngia kētia e te hōhā me te hēmanawatanga. Heoi, ahakoa ngā wheako ake o tēnā, o tēnā, he hiahia nō te nuinga kia matatau ā rātou tamariki me ā rātou mokopuna ki te reo, kia tū pakari ai, kia tū Māori ai ki tēnei ao. Te nuinga o tēnei rōpū he manawanui ki te kōrero Māori i te kāinga i te nuinga o te wā, koia anō rā i ā rātou e kōrero ana ki ā rātou tamariki me ā rātou mokopuna. Heoi anō, kei reira anō ngā papatoieketanga, e pā ana ki ō rātou ake tītengi rānei, ki te takarepatanga o tō rātou reo rānei, me te mōhio anō ko ētahi o ō rātou hoa, whānau, whānau whānui anō hoki, he reo tahi kē, arā, ko te reo Pākehā te reo kawe. Anō hoki, ko ētahi o ngā tamariki, i ā rātou e pakeke haere ana ka kaha papare i te reo Māori, ka whakawaia kētia rātou e te reo Pākehā me ōna tikanga. I waenganui i te hunga i whai wāhi ki tēnei kaupapa rangahau kua kitea he mārama pū te nuinga ki te tino hiranga o te tuku ihotanga o te reo; kua kitea hoki tō rātou kaingākau nui ki te ako i te reo, ki te whakapakari rānei i tō rātou reo. Hāunga tērā, me ō rātou ngana anō ki te kawe i te reo Māori i te kāinga, ko ngā mātua kāore anō kia tino eke te reo ā-waha ka mate i te pōraruraru, te pōkaikaha, te āwangawanga, me te kaha papare a ngā tamariki e pakeke haere ana. Nā runga i tērā, me te take anō hoki he ruarua noa iho ngā wāhi o te hapori whānui i ēnei rā kia taea te reo Māori te rere noa, kua whakapuāwaitia e te tokomaha o tēnei rōpū ētahi rautaki hei ārahi i ngā tamariki me ngā mokopuna i ā rātou e pakeke haere ana, kia mārama rātou ki ngā whakahere tinana a te marea kia whai wāhi ai rātou ki te ako i te reo, me ngā here e haere kōtui ana ki ērā āhuatanga, kia whakanuia, kia utua hoki ngā tamariki i runga anō i ngā whakatutukitanga reo, kia manaakitia hoki rātou ki te whai wāhi anō ki ngā horopaki reo Māori. Hei konei ka ākina rātou ki te uru ki ngā kapa haka me ngā tino kaupapa anō o te ao Māori e whakatairanga nei i te reo. Anō hoki, ka whakahauhautia kia piritata ki ā rātou hoa me ō rātou whanaunga e tino mōhio ki te reo, me te whakauru hoki ki ngā mahinga marae. Waihoki, ka pōwhiritia te hunga matatau ki te reo ki te toro mai ki ō rātou kāinga (nā reira, me whakapau kaha anō ngā mātua ki te whakahoahoa, ki te patipati, ērā tāngata kia whakaae mai ki te noho ki te taha o ngā tamariki whakaputa kōrero ai). Koinei ngā mea ka taea ai e ngā mātua katoa, e ngā kaitiaki katoa, ahakoa kei hea te tohungatanga o tō rātou reo.  Mā reira, ka whai wāhi tonu, ka whakamanahia tonu tēnei hunga e pōhēhē nei pea he iti noa iho tā rātou hei koha atu ki te whakarauoratanga o te reo. Nō reira, hāunga rā te whakaaro he nui ngā mātua me ngā kaitiaki tamariki i tēnei wā e kore e tino whai wāhi ki te tukunga iho o te reo i te kāinga, ehara i te mea he kore noa iho tā rātou hei koha atu ki tēnei kaupapa whakahirahira.
