title: Whistleblowing: The advantages of self-regulation

authors: Bather, Andrea

subjects: accounting

abstract: Although whistleblowers are often portrayed as courageous individuals worthy of respect, the act of whistleblowing can be viewed as a disloyal act which may bring much harm to the whistleblower’s colleagues. We argue that although some whistleblowers have provided a great service to society, the world would be best served if the need for external whistleblowing were to be obviated by appropriate management practices.

title: Quantitative chemical indicators to assess the gradation of compression wood

authors: Nanayakkara, Bernadette

subjects: chemistry of compression wood

abstract: A chemistry-based parameter has been sought for determining the gradation of compression wood (CW), i.e., the severity, in tissues of Pinus radiata wood. Fluorescence microscopy was the reference for characterisation of the tissues containing CW. The collected material contained CW of varying severity, beginning with normal wood (NW containing no CW), continuing with material with some features of CW (CW of mild severity, MCW) and ending up with a material with pronounced features of CW (CW of high severity, SCW). Matching opposite wood (OW) was also included in the study. The chemical analyses included lignin determination, sugar analysis in the acid hydrolysate, thioacidolysis, 31P-NMR spectroscopic analysis and steric exclusion chromatography of thioacidolysis products. As the severity of CW changed progressively from NW through MCW to SCW, all chemical parameters changed concurrently. In particular, levels of galactose and lignin increased, while those of glucose and mannose decreased. The amounts of p-hydroxyphenyl β-ethers released by chemical degradation and uncondensed p-hydroxyphenyl C-9 units also increased at elevated CW severity levels. The amounts of galactose and the p-hydroxyphenyl content of the lignin correlated linearly with lignin for CW samples. The chemical differences between CW and OW in the stem, branch and seedling were similar, i.e., they are independent of the morphological origin of the sample. Parameters based on the p-hydroxyphenyl unit content appear the most suitable chemical indicators of CW severity, as they are least sensitive to the sample's morphological origin and their response to CW severity is high.

title: Keynote Address: Barriers and incentives to Māori participation in the profession of psychology

authors: Levy, Michelle Patricia

subjects: Maori

abstract: It is well known that Māori are overrepresented
within the client group of
psychologists. Despite ongoing attempts to
recruit and retain more Māori within the
discipline of psychology, the numbers of
Māori psychologists continues to remain
low, raising serious concerns about the
ability of the profession to effectively meet
the needs of its clientele. The objectives of this study were to
identify the, barriers to, and incentives for improving the recruitment and retention
of Māori in the profession of
psychology and Māori to gain and maintain registration
as psychologists. This paper is
based on the full report provided to the
New Zealand Psychologists’ Board. The findings in this study
clearly demonstrate that in order to attract
Māori to participate in psychology, the
majority of environments need to change
substantially. It is simply not enough for
organisations, whether they are educational, professional, or service delivery agencies,
to identify the need for more Māori
psychologists, yet still fail to commit to,
and actively engage in, altering long
identified environmental factors that are
barriers to Māori participation.
