title: Characteristics of temporal fluctuations in the hyperpolarized state of the cortical slow oscillation

authors: Wilson, Marcus T.

subjects: bioelectric potentials

abstract: We present evidence for the hypothesis that transitions between the low- and high-firing states of the cortical slow oscillation correspond to neuronal phase transitions. By analyzing intracellular recordings of the membrane potential during the cortical slow oscillation in rats, we quantify the temporal fluctuations in power and the frequency centroid of the power spectrum in the period of time before “down” to “up” transitions. By taking appropriate averages over such events, we present these statistics as a function of time before transition. The results demonstrate an increase in fluctuation power and time scale broadly consistent with the slowing of systems close to phase transitions. The analysis is complicated and limited by the difficulty in identifying when transitions begin, and removing dc trends in membrane potential.

title: The government's dismantling of climate laws breaks years of cross-party agreement

authors: Barton, Barry

subjects: climate change

abstract: Just as world leaders gather for this year’s COP30 climate summit in Brazil, the government’s announcement of its intention to significantly change New Zealand’s climate change law upends years of cross-party consensus.

All of the proposals pose serious problems, but the change to the zero-carbon provisions in the Climate Change Response Act 2002 runs counter to the underlying purpose of the act to provide accountability for climate change policy.

The government proposes to simplify emissions reduction plans, which are produced every five years to set out policies and strategies to decarbonise every sector of the economy.

It also wants to remove the Climate Change Commission’s role in providing independent advice on emissions reduction plans, and allow more frequent revisions of these plans without public consultation. The changes would also adjust timelines for emissions budgets and reports, and relax deadlines for the government’s response.

title: huka can haka: Taonga performing tino rangatiratanga

authors: Nopera, Tāwhanga Mary-Legs

subjects: Raranga

abstract: huka can haka is an ongoing body of creative works used to frame the ideas expressed in this thesis. Spoken, ‘huka’ sounds like ‘hooker’, he is a performance persona developed to help heal from the bitter-sweet reality of being Māori, genderfluid, same-sex attracted and HIV positive in Aotearoa New Zealand. huka can haka refers to an inbetween gendered space of performance where ‘huka’ translates from Māori to English as the sea-foam that gathers between land and sea, white rain such as snow or hail, the dancing tags that are woven into cloaks, or as the transliteration of sugar. ‘Haka’ is predominantly perceived as a masculine form of traditional Māori dance and is akin to weaving with the entire body. Haka is highly sexualised and invigorates a sense of connection to Māori genealogies, family, community, language, land and cultural practices. huka can haka infers the agency enacted through the intentional performance of an identity between cultures and gender in Aotearoa New Zealand. ‘Taonga’ translates from Māori to English to represent things people value and treasure – they can be tangible or ephemeral and include shared and individual memories, people, words, actions, the things we make and beautify, as well as the natural environment that sustains us. ‘Tino rangatiratanga’ is a Māori assertion of the right to determine our lives without the disruptive controls enacted through the New Zealand government by the British Crown. Taonga performing tino rangatiratanga, infers the agency present in valuable things – because taonga exist we become aware of reasons to protect them, we create protective processes and we appreciate the value of ourselves as protectors. huka can haka: Taonga performing tino rangatiratanga explores how making art heals – it describes the transformations that manifest when creating through Māori knowledge.


Raranga is the framework used to organise and explain my research. Raranga is a traditional process of Māori weaving and through its use as a methodology, I am able to connect my explorations to the relational values that are part of Māori culture. I use raranga as a framework to interpret my own practice which is unique to me – there is no separation between my practice and the ways I live my life which differs from the approaches of other weavers. Within this project I utilise a range of research approaches that are qualitative, autobiographical, subjective, creative and practice-based.  Traditional Māori methods of story-telling, pūrākau, are used to communicate this research in digital image, digital video, writing and performance art. Through doing this I describe how contemporary media explorations can be interpreted as forms of raranga and haka, which can help mediate the sometimes oppressive use of text, image, moving image and performance in advancing colonial intents. The primary findings in this research are:
1.	that creative practice research can help people to connect sexuality with creativity, to, re-story and re-generate narratives of empowerment; 
2.	that multimedia approaches to identity knowledge gathering, assists in embodying empowerment;
3.	that Kaupapa Māori Theory can challenge dominant perceptions of gendered Māori bodies, and is inclusive of the ‘do it yourself’ strategies described through Transgender theory;
4.	that a raranga methodology can be embodied through performance and performance artefacts, connecting research to the lived experiences of research subjects;
5.	that raranga is a powerful tool to interpret sexual trauma, offering connective strategies to release damaging internalised behaviours;
6.	that raranga can centre marginal identities as bodies full of hope; 
7.	that performance of historical trauma as ceremony can offer collective forms of healing, and;
8.	that raranga heals, giving direction to multiple and conflicting strands of lived experience.


The thesis makes prominent the generative and progressive nature of raranga and is chronological in design. Theoretical explorations inspire creative works, which then in turn inform avenues for deeper theorisation, leading to new creative works and so on until the thesis conclusion. Through this creative practice research project I assert raranga as a powerful process to interpret the agency that grows between makers, the materials we use and the objects we create. Ultimately, this thesis outlines a way to weave experiences of sexualised and gendered trauma, and affirm the healing present at the intersection between oppositional relationships.
