Time Series Analysis of Disparity between Maori and non-Maori Labour Market Outcomes in the Household Labour Force Survey

Disparity in labour market outcomes between Maori and non-Maori is examined using Household Labour Force Survey (HLFS) data. The paper explores the nature of the ethnicity question and ethnic classification in the HLFS. It shows that there are substantial differences in labour market outcomes between those Maori who report only Maori ethnicity and those who report Maori and another ethnicity ("mixed" Maori). The paper then considers various methods of measuring disparity and uses these to examine the time series behaviour of disparity between 1985 and 1998. It concludes that disparity between Maori and non-Maori is greater today than in 1985. However, all this deterioration occurred between 1985 and 1992. Since 1992 disparity has been in decline. The bulk of time series variation in disparity between Maori and non-Maori has been driven by changes in outcomes for the sole Maori group. Mixed Maori, about a quarter share of the Maori ethnic group, has outcomes which closely track those of the non-Maori population over time

Adaptable P body physical states differentially regulate bicoid mRNA storage during early Drosophila development.

Ribonucleoprotein condensates can exhibit diverse physical states in vitro and in vivo. Despite considerable progress, the relevance of condensate physical states for in vivo biological function remains limited. Here, we investigated the physical properties of processing bodies (P bodies) and their impact on mRNA storage in mature Drosophila oocytes. We show that the conserved DEAD-box RNA helicase Me31B forms viscous P body condensates, which adopt an arrested physical state. We demonstrate that structurally distinct proteins and protein-protein interactions, together with RNA, regulate the physical properties of P bodies. Using live imaging and in situ hybridization, we show that the arrested state and integrity of P bodies support the storage of bicoid (bcd) mRNA and that egg activation modulates P body properties, leading to the release of bcd for translation in the early embryo. Together, this work provides an example of how physical states of condensates regulate cellular function in development

You've got male: Sex and the microbiota-gut-brain axis across the lifespan

Sex is a critical factor in the diagnosis and development of a number of mental health disorders including autism, schizophrenia, depression, anxiety, Parkinson's disease, multiple sclerosis, anorexia nervosa and others; likely due to differences in sex steroid hormones and genetics. Recent evidence suggests that sex can also influence the complexity and diversity of microbes that we harbour in our gut; and reciprocally that our gut microbes can directly and indirectly influence sex steroid hormones and central gene activation. There is a growing emphasis on the role of gastrointestinal microbiota in the maintenance of mental health and their role in the pathogenesis of disease. In this review, we introduce mechanisms by which gastrointestinal microbiota are thought to mediate positive health benefits along the gut-brain axis, we report how they may be modulated by sex, the role they play in sex steroid hormone regulation, and their sex-specific effects in various disorders relating to mental health
