title: Acanthaster planci invasions: applying biosecurity practices to manage a native boom and bust coral pest in Australia

authors: Hoey, Jessica

subjects: seastar

abstract: Coral reef systems are in global decline. In Australia, much of this decline has been attributable to cyclic outbreaks (every ~17 years) of the coral-feeding crown-of-thorns seastar. While a native species, when in large enough densities the seastar acts like an invasive pest. Since 2012 the Australian government has invested significantly in a targeted control program using lethal injection. While this program is effective for individual reefs, it is not a complete strategyfor the entire Great Barrier Reef (~2,500 reefs). In order to find a longer-term solution to the problem, in 2015, the lead author travelled to New Zealand, the United States, and Canada under a Churchill Fellowship to understand successful aquatic integrated pest management strategies and their potential application to the Great Barrier Reef. Meetings and workshops were convened with experts who specialise in risk assessment, categorisation, and management of aquatic invasive species. The experts comprised academics, applied scientists, policy makers, and a not for profit community based invasive species council. Bioinvasion management and prioritisation of management effort using risk-based frameworks were reviewed for application to the crown-of-thorns seastar. This viewpoint is novel in its approach of applying invasive species tools and perspectives to a non-invasive, native marine pest. Early detection and rapid response is key to preventing the transition of the seastar from natural densities to outbreak densities. However given the seastar is a native species already established, when in outbreak mode a multifaceted post-border management approach is essential. Private support funding models, that bridge conservation and tourism/philanthropy have proved successful in New Zealand to supplement government funded marine reserve management – this is an approach which should be explored by Australia to help manage the seastar. Dedicated support and commitment is needed to break the issue-attention cycle. On the Great Barrier Reef, a dedicated biosecurity approach should be used to maintain the seastar at natural densities, increase the time between outbreaks, protect coral cover and increase resilience of the system.

title: Performance of a building integrated photovoltaic/thermal (BIPVT) solar collector

authors: Anderson, Timothy Nicholas

subjects: photovoltaics

abstract: The idea of combining photovoltaic and solar thermal collectors (PVT collectors) to provide electrical and heat energy is an area that has, until recently, received only limited attention. Although PVTs are not as prevalent as solar thermal systems, the integration of photovoltaic and solar thermal collectors into the walls or roofing structure of a building could provide greater opportunity for the use of renewable solar energy technologies. In this study, the design of a novel building integrated photovoltaic/thermal (BIPVT) solar collector was theoretically analysed through the use of a modified Hottel–Whillier model and was validated with experimental data from testing on a prototype BIPVT collector.
The results showed that key design parameters such as the fin efficiency, the thermal conductivity between the PV cells and their supporting structure, and the lamination method had a significant influence on both the electrical and thermal efficiency of the BIPVT. Furthermore, it was shown that the BIPVT could be made of lower cost materials, such as pre-coated colour steel, without significant decreases in efficiency.
Finally, it was shown that by integrating the BIPVT into the building rather than onto the building could result in a lower cost system. This was illustrated by the finding that insulating the rear of the BIPVT may be unnecessary when it is integrated into a roof above an enclosed air filled attic, as this air space acts as a passive insulating barrier.

title: Hoea te waka reo e 'Āti Rangi ē! He Kohinga Kōrero

authors: Fairhall, Tīahomarama Te Haana

subjects: Māori

abstract: He taonga tuku iho Te Reo Māori nō tāukiuki, nō tuawhakarere, nō onamata rānō, he kākano i ruia mai i Rangiātea. He taonga Te Reo Māori i raro i ngā tikanga o Te Tiriti o Waitangi, ā, nō te tau 1987 ka whakamanahia hai reo tūturu o Aotearoa. Ahakoa he reo tuku iho ki tērā whakatupuranga, ki tērā whakatupuranga, kai te tāmate te reo. He huhua noa ngā rautaki e whakarauora ai i te reo i roto i ngā kura, i ngā whānau, i ngā hapū, i ngā iwi anō hoki. 

Ko te tino o te tuhinga roa nei he āta titiro ki ngā momo rautaki a ngā uri e whakarauora nei i tō tātou reo ki roto o Ngāti Rangiwewehi kia kore ai ā mātou tamariki, ā mātou mokopuna e haere reo kore. Nō roto mai i te tuhinga nei ka āta whakatewhatewha te iwi o Ngāti Rangiwewehi o mua, kia mārama ai ki ōna āhua, ki ōna whenua, ki āna kōrero, ki ōna tāngata, ki ōna pūkōrero, ki tōna ahurei. Ka mutu, ka āta titiro, ka āta tātari, ka āta wetewete i ngā raraunga kōrero i kapo mai i ngā uiuinga, i kapo mai i ngā pātaitai, i kapo mai i ngā pukapuka kōrero ngā momo rautaki e whakarauora ai te reo o ngā uri o Ngāti Rangiwewehi. Hai āpitihanga, ka āta whakatakoto hoki i ngā piki me ngā heke o te reo ā tatauranga nei, ka kitea te ahunga mai i te wā i a koroua mā, i a kuia mā, ā, moroki noa nei.

Kai roto i ngā upoko o te tuhingaroa nei te tino ia o ngā kōrero, ā, e ono ngā upoko e whakatinana ai tēnei rangahau. Kai te upoko tuatahi e tino kōrerohia ana te iwi o Ngāti Rangiwewehi. Kātahi rā ka uru atu ki ngā whakamahukitanga o ngā mātāpono rangahau kai te upoko tuarua. Ka whakaara mai te upoko tuarua i ngā kaponga ariā me ngā rautaki reo hai tuarā mō te tuhingaroa nei. Kai te upoko tuawhā me te tuarima ngā pitopito kōrero, ngā putanga o te pākiki me ngā uiuinga. Ka mutu mai ki te upoko tuaono, ki te kupu whakamutunga o te tuhingaroa.

The Māori language is a taonga protected under the terms of Te Tiriti o Waitangi. An official language of New Zealand, since 1987. However, although a language passed down from generation to generation, the future of the language is not secure. Efforts are endless in providing many strategies of revitalization and ensuring that Te Reo Māori survives within kura, whare wānanga, whānau, hapū and iwi. The purpose of this research is to gather information pertaining to the tribe of Ngāti Rangiwewehi. This study will explore Ngāti Rangiwewehi in a traditional context, their traditional qualities and will also examine the contributions of the descendants in preserving Te Reo Māori. Furthermore, this study will also examine the ups and downs of the language and how Ngāti Rangiwewehi rates statisticaly in the national census under Te Reo Māori. This information will be gathered to examine strategy examples of Te reo that could benefit both present and future generations. As part of my research I will be interviewing key informants and conducting a survey. There are six chapters to this thesis. Chapter one is based on Ngāti Rangiwewehi as a iwi, past and present. Chapter two is based on the research methodology. Chapter three is the literature review, while Chapter four is the questionnaire. Chapter five are the interviews and lastly Chapter 6, the conclusion.
