title: Maximum gradient dimensionality reduction

authors: Luo, Xianghui

subjects: Science & Technology

abstract: We propose a novel dimensionality reduction approach based on the gradient of the regression function. Our approach is conceptually similar to Principal Component Analysis, however instead of seeking a low dimensional representation of the predictors that preserve the sample variance, we project onto a basis that preserves those predictors which induce the greatest change in the response. Our approach has the benefits of being simple and easy to implement and interpret, while still remaining very competitive with sophisticated state-of-the-art approaches.

title: Political inclusion as a means of generating Justice for children

authors: Munn, Nicholas

abstract: I argue that the position of children can be improved by ensuring them political representation, through inclusion in democratic processes. Embedding children as equal participants in democratic processes is likely to diminish the structural disadvantages to which they are currently subjected within modern democracies. Political and social institutions will have greater incentives to act proactively to support children, and children will have the same ability as other citizens to express their approval or disapproval of public actions undertaken on their behalf. In a global environment still characterised primarily by independent nation states, democracies provide the most fertile ground for the generation of just institutions. Those institutions work best, for the most active participants in the democracy. Children are, in all states, expressly excluded from active political participation, and as such their voices, desires, needs and rights are marginalised. Political inclusion for children is a first step to address this marginalisation.

title: Decolonisation through reconciliation: The role of Pākehā identity

authors: Amundsen, Diana Leigh

subjects: Pākehā

abstract: Research indicates that claiming a contemporary identity as Pākehā is being redefined by those individuals who engage closely with Te Ao Māori. This reopens the discussion of the implications for Pākehā researchers who engage across Māori research spaces. This article reports a reflective study I conducted using the transtheoretical model and its six stages of change (J. O. Prochaska & DiClemente, 1982) to understand my Pākehā cultural identity. I discuss my rationale for engaging in research with Māori, and then outline the approaches that I, as a non Indigenous researcher, adopted to appropriately engage in Indigenous research. I discuss responsibilities for Pākehā to take deliberate and conscious steps to decolonise through reconciliation and dismantle disturbing and prevailing prejudiced attitudes. Decolonisation through reconciliation takes various forms, but necessarily involves a process of actions and changes. Our challenge as Pākehā educators is to participate in this change process towards decolonisation through reconciliation.
