title: Genetic diversity of soil invertebrates corroborates timing estimates for past collapses of the West Antarctic Ice Sheet

authors: Collins, Gemma Elyse

subjects: climate change

abstract: During austral summer field seasons between 1999 and 2018, we sampled at 91 locations throughout southern Victoria Land and along the Transantarctic Mountains for six species of endemic microarthropods (Collembola), covering a latitudinal range from 76.0°S to 87.3°S. We assembled individual mitochondrial cytochrome 𝘤 oxidase subunit 1 (COI) sequences (𝘯= 866) and found high levels of sequence divergence at both small (<10 km) and large (>600 km) spatial scales for four of the six Collembola species. We applied molecular clock estimates and assessed genetic divergences relative to the timing of past glacial cycles, including collapses of the West Antarctic Ice Sheet (WAIS). We found that genetically distinct lineages within three species have likely been isolated for at least 5.54 My to 3.52 My, while the other three species diverged more recently (<2 My). We suggest that Collembola had greater dispersal opportunities under past warmer climates, via flotation along coastal margins. Similarly increased opportunities for dispersal may occur under contemporary climate warming scenarios, which could influence the genetic structure of extant populations. As Collembola are a living record of past landscape evolution within Antarctica, these findings provide biological evidence to support geological and glaciological estimates of historical WAIS dynamics over the last ca. 5 My.

title: Relevance of corporate governance practices in charitable organisations: A case study of registered charities in New Zealand

authors: Reddy, Krishna

subjects: allocative efficiency

abstract: Purpose – The purpose of this paper is to examine whether the registered charities in New Zealand have adopted the principle-based corporate governance practices similar to those adopted by the publicly-listed companies and the effect corporate governance practices have on their financial performance measured by technical efficiency, allocative efficiency and quick ratio. The paper addresses four important questions: how registered charities in New Zealand are managed and controlled; whether the funds donated to registered charities are utilised effectively; the nature of the corporate governance practiced by registered charities in New Zealand; and the nature of compliance to the Charities Act 2005. 
Design/methodology/approach – Panel data for the registered charities over the period 2008-2010 are analysed using ordinary least squares (OLS) regression and Tobit model regression. Technical efficiency, allocative efficiency and quick ratio are used as the dependent variables. 
Findings – The findings indicate that there is no reporting requirement for the registered charities under the Charities Act 2005 to report detailed information regarding the board make-up, board committees, board meetings, etc. and therefore, registered charities have not reported such information. The results show also that board gender diversity is an important corporate governance mechanism to mitigate agency problem in charitable organisations in New Zealand. However, large board size and large donors have potential to increase agency costs in charitable organisations in New Zealand. 
Research limitations/implications – Caution should be exercised when interpreting and generalising the paper's results, as this study is a case study of registered charities in New Zealand and data comprised only large charities that have revenue over NZ$20?m. It should also be noted that there was a small sample size, which may have had a bearing on the results. 
Practical implications – This study offers insights for policy makers and practitioners interested in adopting similar corporate governance practices within their country. 
Social implications – Within New Zealand, issues relating to management and control of charitable organisations are better understood and as a consequence, development of sector-wise standards could be initiated. 
Originality/value – This research is novel as it investigates the nature of corporate governance practices relating to the registered charities in New Zealand. The availability of data provided by Charities Commission made this research possible.

title: On equality and colourblindness

authors: Robertson, Neville

subjects: Maori

abstract: "I have a dream that my four children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character." So said Martin Luther King, Jr, just over 40 years ago, in a speech that galvanised the US civil rights movement. King spoke of the United States but his dream is equally relevant in New Zealand. Has it been achieved? Some people would argue that not only has it been achieved but that the tables have been turned and now white folk are the ones who are oppressed. What is needed, they argue, is a level playing field. But how level is the playing field?
