title: Contribution of soil bacteria to the atmosphere across biomes

authors: Archer, Stephen D.J.

subjects: Atmospheric microbiology

abstract: The dispersion of microorganisms through the atmosphere is a continual and essential process that underpins biogeography and ecosystem development and function. Despite the ubiquity of atmospheric microorganisms globally, specific knowledge of the determinants of atmospheric microbial diversity at any given location remains unresolved. Here we describe bacterial diversity in the atmospheric boundary layer and underlying soil at twelve globally distributed locations encompassing all major biomes, and characterise the contribution of local and distant soils to the observed atmospheric community. Across biomes the diversity of bacteria in the atmosphere was negatively correlated with mean annual precipitation but positively correlated to mean annual temperature. We identified distinct non-randomly assembled atmosphere and soil communities from each location, and some broad trends persisted across biomes including the enrichment of desiccation and UV tolerant taxa in the atmospheric community. Source tracking revealed that local soils were more influential than distant soil sources in determining observed diversity in the atmosphere, with more emissive semi-arid and arid biomes contributing most to signatures from distant soil. Our findings highlight complexities in the atmospheric microbiota that are relevant to understanding regional and global ecosystem connectivity.

title: Do Golden Parachutes increase CEO’s DESIRE to be taken over? empirical evidence from australia and united states

authors: Reddy, Krishna

subjects: change in control payments

abstract: This study investigates whether the large payouts that are available to Chief Executive Officers (CEOs) from a change in corporate control (takeover) do motivate some CEOs to seek acquisition of their firms by making them more attractive to a takeover bid. Using Australian and the US data, employing OLS regression, we report that there is a significant relationship between a CEOs change in control payments and their firm’s net cash levels (one of the key factors of takeover attractiveness). Our empirical results also indicate that CEOs desire their firms to be acquired by decreasing shareholders’ equity, thus supporting the view that change in control payments exist primarily for incumbent managers. Our findings provide support to the proposition that managers enjoy having large cash balances to be available to them as it allows them with greater opportunities to derive personal benefit from it. Therefore, our findings suggest that managers prefer to have large cash balances available to them to ensure their future wellbeing by setting up favourable terms in the control agreements.

title: Inspiring national indigenous legal education for Aotearoa New Zealand's Bachelor of Laws Degree: Phase One

authors: Ruru, Jacinta

subjects: tikanga Maori, LLB law degree, legal education in New Zealand, bilculturalism, bilinguaiism, bijuralism

abstract: This Issues Paper is the result of the first stage of a multi-year, three-phase national project. In it we review the literature and consider some of the preliminary opportunities relevant for the teaching
of Māori law as a foundation source of the Aotearoa New Zealand Bachelor of Laws (LLB) degree for the benefit of the legal profession and Aotearoa New Zealand society. We present ten key messages
as integral to this Issues Paper.
