title: Exact solutions for steady state incompressible magnetic reconnection

authors: Craig, Ian J.D.

abstract: The problem of steady state magnetic reconnection in incompressible, resistive plasmas is addressed. It is shown that families of exact analytic solutions can be derived by exploiting the formal symmetry between the magnetic field lines and the streamlines of the flow. These solutions, while incorporating previous models for antiparallel magnetic merging, assume no inherent topological symmetry for the reconnective geometry. It is demonstrated that fast reconnection occurs within a narrow X-type configuration defined by the intersection of two separatrix lines. One separatrix line is undistinguished physically, but the other is contiguous with a global current sheet across which there is no plasma flow. The implication is that fast reconnection is more likely to be associated with strong shearing motions close to the neutral point rather than with the conventional stagnation point flow topology.

title: Looking within and beyond the community: Lessons learned by researching, theorising and acting to address urban poverty and health

authors: Hodgetts, Darrin

subjects: advocacy

abstract: Urban poverty and health inequalities are inextricably intertwined. By working in partnership with service providers and communities to address urban poverty, we can enhance the wellness of people in need. This article reflects on lessons learned from the Family100 project that explores the everyday lives, frustrations and dilemmas faced by 100 families living in poverty in Auckland. Lessons learned support the need to bring the experiences and lived realities of families to the fore in public deliberations about community and societal responses to urban poverty and health inequality.

title: The “standard story” of anti-Māori talk in Pae Ora (Healthy Futures) Bill submissions

authors: Black, Rose

abstract: AIM: To review some common patterns of race talk in a sample of submissions made to the Pae Ora (Healthy Futures) Bill. This bill proposed a structural reform of the health system in Aotearoa New Zealand to address long-standing health inequities experienced by Māori, the Indigenous peoples, and other priority populations. METHOD: In a sample of 3,000 individual submissions made in late 2021, we found 2,536 explicit references to race. Utilising the “stan-dard story” frame of Pākehā/non-Maori race talk, five longer submissions that inferred that the Pae Ora bill was “racist” were analysed in detail. RESULTS: Many “standard story” race discourses were identified in the Pae Ora submissions. Three derived discourses included in this paper are: Pākehā as norm (monoculturalism or not seeing Pākehā as a culture), equality and the “Treaty” (equality for all to access healthcare), and one people (we are all New Zealanders). Sources such as the Waitangi Tribunal Wai 2575 Hauora report were drawn on to provide alternative discourses. CONCLUSION: Identifying Pākehā standard story discourses enables learning about language patterns systems draw on, and the development of tools and procedures to improve equity for Māori and eliminate institutional racism.
