title: Complete sets of functions for perturbations of Robertson–Walker cosmologies and spin 1 equations in Robertson–Walker-type space-times

authors: Kalnins, Ernie G.

subjects: Mathematics

abstract: Crucial to a knowledge of the perturbations of Robertson–Walker cosmological models are complete sets of functions with which to expand such perturbations. For the open Robertson–Walker cosmology an answer to this question is given. In addition some observations concerning explicit solution by separation of variables of wave equations for spin 1 in a Riemannian space having an infinitesimal line element of which the Robertson–Walker models are a special case are made.

title: Are Asia-Pacific real exchange rates stationary? A regime-switching perspective

authors: Holmes, Mark J.

subjects: purchasing power parity

abstract: This paper tests for long-run purchasing power (PPP) among nine Asia-Pacific countries. Non-stationarity of the real exchange rate is tested within a Markov regime-switching framework. Two new concepts of PPP are defined that allow for real exchange behaviour to switch between stationary and non-stationary regimes (partial PPP) or between stationary regimes of differing degrees of persistence (varied PPP). The results indicate that each country is characterized by at least one stationary regime. Indeed, five countries are characterized by two such regimes. Further analysis indicates that the Asian crisis of 1997 gave mixed impetus to the achievement of long-run PPP.

title: Te Mātaiaho as curricular justice?

authors: Shafer, Derek

abstract: Te Mātaiaho produces a version of curricular justice which aims to give effect to Te Tiriti and address long-standing inequities in education in Aotearoa New Zealand. We examine Te Mātaiaho’s vision for subject English and its construction of students’ identities as fundamental to a curriculum that advances both bicultural nationhood and just outcomes for all students. We draw on Raewyn Connell’s (2010) model of curricular justice, and Nancy Fraser's (2017) notion of progressive neoliberalism to explore the opportunities and implications for subject English within Te Mātaiaho's vision. How might these frameworks for justice help to critique the development of educational policy and support the implementation of Te Mātaiaho's vision for biculturalnationhood and just outcomes for all students.
