title: “You’re not coming out – you’ve been there all along and just no one’s looked”: Māori LGBT+ youth and identity exploration

authors: Laurence, Rebekah

subjects: Māori

abstract: This research is a Masters-level project on Māori LGBT-plus (lesbian, gay, bisexual, transgender, and other) youths’ experience of exploring their gender and sexual identities, highlighting how whānau (loosely, ‘extended family’) can provide mana (authority, power) such that youth can exercise mana rangatiratanga (a Maniapoto description of ‘autonomy, self-determination’) regarding their identities. This is a novel, exploratory study.
Adapted elements from a Mana Wāhine (Māori feminist) perspective of Kaupapa Māori theory comprised the theoretical framework for this project. These elements were Mana rangatiratanga (adapted from Tino rangatiratanga), Te reo Māori me ōna tikanga (Māori language and its culture), and Whanaungatanga (relationships). The three elements were adapted to fit a Ngāti Maniapoto worldview. 
Qualitative research methods were used for this study. There were five participants aged between 17 and 24 years, who were Māori and had diverse gender or sexual identities. Semi-structured, face-to-face interviews were conducted with participants, which allowed them to share their experiences of exploring their gender and sexual identities and of whānau support. Interviews were analysed using a process of inductive thematic analysis, which identified and analysed patterns across the dataset.
Eight themes were derived from participants’ experiences. These themes were Ko Tūhura, which described the process of discovery that participants have experienced; Ko Matatapu, which described participants’ experience of authenticity and concealment of their gender and sexual identities; Ko Tautoko, which described how whānau have empowered participants to explore their identities, and how participants have been denied empowerment; Ko Mata-ngaro, which described participants’ early lack of exposure to diverse identities, and their having their identities unseen by others; Ko te Ahunga-ki-te-aunoa, which described how diverse identities have been accepted within participants’ whānau; Ko Tauawhi, which described how participants have been embraced for their diverse identities; Ko Mata-pū-take, which describes participants’ experience of finding somewhere to belong; and Ko Kiritau, which describes participants’ becoming settled in their expression of their gender and sexual identities.
The findings of the thesis describe roles that whānau play in participants’ exploration of their gender and sexual identities and some of the effects that colonisation has had within participants’ whānau regarding their gender and sexual identities. Nonetheless, participants actively resisted these aspects of colonisations and found ways to give voice to their gender and sexual identities.
Given that participants shared that there was a dearth of information regarding gender and sexual identities available to them within their whānau and school environments, organisations within psychology and related fields may work to proactively provide all young Māori people and their whānau with information regarding diverse gender and sexual identities. Moreover, to address the dearth of resources designed for Māori LGBT-plus youth, New Zealand-based researchers may collate information specifically regarding Māori LGBT-plus youth experience of identity exploration and Māori knowledges regarding gender and sexual identities. This information may be collated in community-based resources that are designed specifically for members of this group and their whānau, and professionals who work for them.

title: Studies on Paphies australis (Mesodesmatidae) in Whangārei, Aotearoa New Zealand: an investigation into their declining health.

authors: Howells, Joanne Elizabeth

abstract: Disease outbreaks in marine species can have devastating consequences, including increasing host mortality, destabilising commercial production, altering ecosystem functioning, and jeopardising human health. A changing ocean climate is expected to increase host stress and the risk of disease outbreaks. Particularly through new and emerging diseases and opportunistic infections.
Wild bivalve molluscs provide economic, ecological, and socio-cultural benefits. Healthy and sustainable kaimoana (shellfish/bivalves, seafood) are intrinsically linked to the wellbeing of many communities in New Zealand. Over the past decade there has been a noticeable decline in the general health of native marine bivalves, characterised by an increase in observation of mass die-offs. Reasons for this are not clear and could be due to a number of factors, such as sedimentation, harvesting pressures, or disease. Baseline health data on wild bivalve populations are very rare and therefore it is very difficult to identify the causation of ill health. There is a need to establish health baselines to help benchmark changes in infection prevalence and intensity and identify drivers of bivalve mortality events.
Wild bivalve populations are often located in remote and isolated parts of New Zealand. When a mortality event occurs, the logistics of obtaining quality samples for accurate diagnosis can be hindered due to time delays and sample degradation. To gain a better understanding of these limitations for diagnostics using bacteriology, in Chapter 2 I investigate typical sample collection methods (i.e., samples collected and sent to a testing laboratory) and sample collections immediately in the field to understand what effect different sample methods have on number and types of bacteria isolated. Although the results of Chapter 2 found there were limitations to both sampling methods, it did identify that typical sampling techniques were not wholly optimal, and the information gained by sampling immediately in the field retained additional information that could be essential for disease diagnostics. Field sampling for bacteriology was applied throughout this thesis research.
Pipi (Paphies australis) are native bivalves to New Zealand, inhabiting the shallow subtidal of estuaries and bays. Pipi have suffered serious population declines in an area of northern New Zealand (Whangārei) since 2009. I investigate possible drivers of the poor health of pipi in Whangārei, with the objective of identifying the mechanisms that have contributed to the decline, and prevention of the recovery of pipi in Whangārei, with a primary focus of disease as a causative agent. I establish a health baseline of pipi from Whangārei using histopathology, bacteriology, and qPCR of Endozoicomonas spp., a bacteria previously identified in mortality bivalves (Chapter 3). The health baseline was compared against samples collected during three mass mortality events to help identify drivers of mass mortality events (Chapter 4). Through laboratory experimentation, I test whether pipi exposed to stressors had higher infection intensity and prevalence of Endozoicomonas spp. (Chapter 5). Finally, using archived samples, I test whether the baseline data established was consistent through time and help to provide insights into considerations when analysing bivalve mass mortality events (Chapter 6).
I found that Endozoicomonas spp. make an important part of pipi host microbiome. Although Endozoicomonas spp. are highly prevalent in pipi collected during a mass mortality event, their infection intensity was significantly lower in moribund pipi than healthy pipi. The prevalence and infection intensity of Endozoicomonas spp. were not driven by environmental stressors. The stressors, however, did appear to impact host health, with high suspended sediment loads and water temperatures of 24°C appeared to be unfavourable to pipi. Overall, Endozoicomonas sp. does not appear to be a main driver in the declining population of pipi from Whangārei and is probably not important to bivalve health. The reduced prevalence and infection intensity of Endozoicomonas sp. in healthy pipi strongly suggests these bacteria are symbiotic. A relationship that has been reported for this bacterial group in species of coral and sponges.
The establishment of a health baseline represents a significant step forward towards biosecurity preparedness by being able to identify changes in infection prevalence and intensity against it. The operational use of these data when paired with historical data will be a powerful tool to identify patterns of disease dynamics and emerging disease.

title: Modular Supervisor Synthesis for Extended Finite-State Machines Subject to Controllability

authors: Malik, Robi

subjects: Science & Technology

abstract: This paper proposes an algorithm for the synthesis of modular supervisors using extended finite-state machines, i.e., state machines with variables and guards on the transitions. Synthesis is performed by iteratively selecting components from a synchronous composition until a least restrictive controllable solution is obtained. This method is usually faster and produces smaller supervisors than standard monolithic synthesis, while offering the modelling benefits of variables. An example of manufacturing system control illustrates the approach.
