‘The White Hordes From the West’: Race and Refuge in Australian Media Commentary About White Rhodesians During Zimbabwe's Decolonisation

Australian Journal of Politics &History, EarlyView.
ABSTRACT This article explores Australian media commentary on white Rhodesians migrating to Australia, focusing on the period of Malcolm Fraser's prime ministership (1975–1983). The main argument is that the Australian media debates about whether to classify white Rhodesians as ‘migrants’ or ‘refugees’ were not merely semantic but reflected a deeper ...

Addressing Bias in Non‐Probability Fisheries Surveys Using Multilevel Regression and Poststratification Approaches

Fish and Fisheries, EarlyView.
ABSTRACT Quantifying harvest of fish stocks is challenging as census data are often unavailable, so surveys are required. Traditional probability‐based surveys use random sampling to obtain representative data that can be scaled to estimate total impact.

Prediction of velocity and attitude of a yacht sailing upwind by computational fluid dynamics

International Journal of Naval Architecture and Ocean Engineering, 2016
One of the most important factors in sailing yacht design is accurate velocity prediction. Velocity prediction programs (VPP's) are widely used to predict velocity of sailing yachts. VPP's, which are primarily based on experimental data and experience of

After the Hype: Resilience Seeking in Emerging Technology Ecosystems

Journal of Product Innovation Management, EarlyView.
ABSTRACT Academic Summary Hype often helps emerging technology ecosystems gain early support for their innovative value propositions, but the initial excitement around the technology typically vanishes at some point. This decrease in excitement and support may lead some ecosystems to fail while others are resilient and recover.

The Cognitive Costs of Sleep Deprivation in Ultra‐Endurance Cycling: Insights From the Race Across France

Journal of Sleep Research, EarlyView.
ABSTRACT For athletes in endurance sports, who compete over several days and in unpredictable conditions, managing sleep–wake rhythms is critical to ensure optimal performance and minimise the risks to safety. Despite its growing popularity, the role of sleep management on ultracycling performance has received little attention.
