Career optimism and job-related well-being of Australian nurses during COVID-19: A cross-sectional study.

Background: Australia has been confronted with a severe nursing deficit, making it difficult to maintain a strong healthcare workforce capable of meeting the mounting demands of healthcare organizations.

Aims: This study aimed to understand how personal and organizational resources influence career optimism and job-related affective well-being of Australian nurses during a pandemic using the Conservation of Resource Theory.

Methods: A cross-sectional online survey was emailed to 123 Australian nurses from January to February 2021.

Paternalistic leadership as a double-edged sword: Analysis of the Sri Lankan President's response to the COVID-19 crisis.

Despite the challenges facing small economies, leadership research has given scant attention to leaders' behaviour in those countries during crises. Using seemingly paradoxical domains of paternalistic leadership theory: authoritarian, benevolent and moral leader behaviour, together with concepts like populism from the political science domain, we analyse how Sri Lanka's 'strongman' President provided a façade of paternalistic leadership during the first phase of the COVID-19 pandemic. Through analysis of written and verbal content (public speeches, independent reports and government media output), we show how the power exercised through authoritarian, as opposed to authoritative behaviour, together with espoused morality and benevolence, appears to have been effective in the short term in containing the pandemic.

N-acyl homoserine lactone-degrading microbial enrichment cultures isolated from Penaeus vannamei shrimp gut and their probiotic properties in Brachionus plicatilis cultures.

Three bacterial enrichment cultures (ECs) were isolated from the digestive tract of Pacific white shrimp Penaeus vannamei, by growing the shrimp microbial communities in a mixture of N-acyl homoserine lactone (AHL) molecules. The ECs, characterized by denaturing gradient gel electrophoresis analysis and subsequent rRNA sequencing, degraded AHL molecules in the degradation assays. Apparently, the resting cells of the ECs also degraded one of the three types of quorum-sensing signal molecules produced by Vibrio harveyi in vitro [i.
