title: Killing Tensors and Variable Separation for Hamilton-Jacobi and Helmholtz Equations

authors: Kalnins, Ernie G.

subjects: Science & Technology

abstract: Every separable coordinate system for the Hamilton-Jacobi equation on a Riemannian manifold Vₙ corresponds to a family of n-1 Killing tensors in involution, but the converse is false. For general n we find a practical characterization of those involutive families of Killing tensors that correspond to variable separation, orthogonal or not.

title: Lake Rotoiti catfish incursion: Something new or the Emergence of an old problem?

authors: Hicks, Brendan J.

abstract: Kia ora everybody. I have been involved in pest fish research, control and generally understanding their life history and what we might do about them. For a number of years I have been called in by Bay of Plenty Regional Council to help with the catfish problem and I ask, ‘Is this something new or the emergence of an old problem?’ I suggest that maybe we have been waiting for this in Rotoiti but hoping that it would not happen.

title: Holding a mirror to society? Sociodemographic diversity within clinical psychology training programmes across Aotearoa.

authors: Scarf, Damian

subjects: Education, Medical

abstract: It has recently been demonstrated by Crampton et al that there has been a marked increase in the sociodemographic diversity of the University of Otago’s health professional programmes between 2010 and 2016.1 This change is evidenced by the fact that a historic 76 health professional Māori graduates crossed the Dunedin Town Hall stage in December 2018. A key driver of this change was the University of Otago’s Division of Health Sciences Mirror on Society selection policy. Here, by documenting the sociodemographic diversity of an equally important professional programme, clinical psychology, we highlight the need for similar selection policies to be implemented Aotearoa/New Zealand wide.
