    Applying Materiality Judgements
    (SSRN, 2023-11-10) Botica Redmayne N; Ehalaiye D; Ahmad F; Edeigba J; Laswad F
    This is a research report prepared for the New Zealand Accounting Standards Board (NZASB) of the External Reporting Board (XRB) on how the International Accounting Standards Board's (IASB's) requirements and guidance on materiality are applied to improve disclosures in general purpose financial statements.

    Tackling plastic pollution in the commercial fishing industry (fin-fish supply chain). Case Study: Moana New Zealand
    (Association of Commonwealth Universities, 2020-09-10) Croft F; Farrelly T
    This report provides an examines the ways in which plastics are used throughout the daily fin fish operations (fin fish) at Moana FisheriesNew Zealand. It explores current global, regional and national policies, as well as current initiatives that are seeking to minimise marine plastic pollution, and how these may be implemented in this context. This study also acknowledges the significant role that industry can play to improve management of plastics by working towards the top of the Zero Waste Hierarchy (redesign/rethink/reduce and reuse).

    Genome-wide identification of novel small RNAs in Pseudomonas aeruginosa
    (2013-09-30) Gomez-Lozano M; Molin, S
    Bacterial small regulatory RNAs (sRNAs) are known to have regulatory functions in a variety of processes including metabolic reactions, stress responses and pathogenesis in response to environmental signals. Recent genome-wide studies to identify sRNAs have been largely based on tiling arrays and RNA sequencing (RNAseq) technologies. The latter approach, in particular, has revolutionized sRNA discovery by enabling interrogation of the transcriptome at unprecedented depths. The size and complexity of the P. aeruginosa genome suggests that it encodes many hitherto undetected sRNAs. In this study, RNA-seq is used to identify sRNAs in P.aeruginosa using a combination of three different sequencing libraries. Over 750 novel sRNAs (including intergenic and cis-encoded sRNAs) have been identified with this approach in this study. The results also reflect that although the use of three libraries increased the number of novel transcripts identified, there were significant differences in the subset of transcripts detected in each library, underscoring the importance of library preparation strategy and relative sRNA abundance for successful sRNA detection. These data will be useful for the study of regulatory sRNAs in P. aeruginosa and the approach described here may be applied to identify sRNAs in any bacterium under different growth and stress conditions. In addition the role of sRNA OsiS was investigated. OsiS was identified in our genome-wide search of sRNAs in P. aeruginosa. OsiS is highly transcribed during oxidative stress conditions. We show that by inducing the expression of OsiS the levels of the sRNA PhrS are greatly reduced. PhrS activates the translation of the pqsR gene under low oxygen concentrations, which in turn activates the synthesis of the Pseudomonas quinolone signal (PQS). Thus, OsiS links the oxygen levels to the production of quorum sensing (QS) molecules. It is hypothesized that the interaction is by direct base-pairing between the two sRNAs, with a predicted recognition site of OsiS at the highly conserved-region of PhrS. However, more experiments are required to know the exact nature of the interaction between these two sRNAs. Notably, OsiS is, to the best of our knowledge, the first sRNA whose main function seems to be regulating the cellular levels of another sRNA.

    Proactive post-occupancy evaluation
    (Build Magazine, 2021-08-02) Rasheed E; Rotimi J; Vilasini N; Weerasinghe A
    A digital post-occupancy evaluation system for checking the operational performance of commercial buildings will be a useful tool as New Zealand faces the need to meet stringent carbon targets.

    Severity Testing: A Primer
    (2020-04-01) Perezgonzalez J
    This is a primer on Mayo's severity testing technology, briefly explaining step by step the implications of severity in the context of rejection and retention of point nil hypotheses, of (conceptually broader) null hypotheses, and of confidence intervals. I finish proposing the use of a confidence interval heuristic for assessing Mayo's severity straightforwardly. In the present article we shall not concern ourselves with wars, whether statistical or philosophical. Instead, we shall work on a philosophical concept being put forth by Mayo in the last two decades (e.g., Mayo, 1983, 1991, 1996; Mayo & Spanos, 2006, 2010), more recently so with her book Statistical Inference as Severe Testing (Mayo, 2018). Severity testing stands for a procedure a researcher can avail of to falsify (frequentist) hypotheses; yet it may spill beyond that bin to become a broader philosophical approach that can serve to also falsify (Bayesian) models (Gelman & Shalizi, 2013), even entire theories. The article I present here is going to be a primer on Mayo’s severity concept in the frequentist realm. However, I sympathise with Gelman and reckon the unstated goal is to advance such primer as a step towards using severity in line with Gelman’s ideas and further, including Taleb’s own use of falsification as a tool to get more acquainted with what our models and theories prevents us from learning, such as about extreme events and Black Swans (e.g., Taleb, 2005, 2010).

    Plastic pollution prevention in Pacific Islands: Gap Analysis of Current Legislation, Policies and Plans
    (EIA, 2020-08-01) Farrelly T; Borrelle S; Fuller S
    Using a gap analysis, this study aims to identify the current limitations in national plastic pollution policy for preventing plastic pollution. It also explores the potential to implement best practice for the reduction of plastic pollution and the promotion of a safe circular plastics economy.
