Was fatigue a contributor to the Titanic disaster? Quite possibly. This study draws on several sources to try and piece together the probable effects of sleep loss (** sources not including Celine Dion or paintings of French girls). Don’t read into this too much, but just a fun little study. Extracts: · “The Titanic’s lookouts, more… Continue reading Watchkeeping, sleep loss, and circadian misalignment in the Titanic disaster

The Role of ESG Performance in Reducing Occupational Accidents: The Moderating Effect of Board Diversity
The Role of ESG Performance in Reducing Occupational Accidents: The Moderating Effect of Board Diversity This explored the links between ESG performance and occupational accidents, and the effect of board diversity. 211 matched pairs of Taiwanese companies were included (those reporting vs those not reporting accident data), with a total sample of 422 firms. Extracts:… Continue reading The Role of ESG Performance in Reducing Occupational Accidents: The Moderating Effect of Board Diversity
E59: Predictors of the use of higher-order risk controls

Safe As – upcoming ep schedule and new format teaser
Next Safe As ep line-up all recorded and ready to rock. Also, the video is a janky practice run, and not-so-subtle clue, to the new ‘neighbourhood’ that Safe As is moving into. (…Been a while since I had to edit videos. For those interested – C64 recorded on an emulator because I couldn’t be bothered… Continue reading Safe As – upcoming ep schedule and new format teaser
Knowledge in the head vs the world: And how to design for cognition. Norman – Design of Everyday Things
Here Don Norman discusses knowledge in the head vs knowledge in the world – from The Design of Everyday Things. Extracts:· “Every day we are confronted by numerous objects, devices, and services, each of which requires us to behave or act in some particular manner. Overall, we manage quite well” · “Our knowledge is often quite incomplete,… Continue reading Knowledge in the head vs the world: And how to design for cognition. Norman – Design of Everyday Things
Human-centred design and the arbitrariness and fussiness of machine design
More wisdom from Don Norman on human-centred design and his error credo (which in later work he extends to humanity-centred design): · “Pinning the blame on the person may be a comfortable way to proceed, but why was the system ever designed so that a single act by a single person could cause calamity?” · “Eliminate the… Continue reading Human-centred design and the arbitrariness and fussiness of machine design
Artificial intelligence fails to outperform orthopaedic surgeons: A systematic review
This compared AI performance to orthopaedic surgeons within clinical practice and training. It’s a systematic review with 16 studies being included. As far as I can, most (all?) studies used ChatGPT 3.5 and 4 (so note the older models). And, yes, pitting surgeons against AI isn’t the ideal use-case (e.g. compared to co-agents/HAIT) Extracts: · “ChatGPT… Continue reading Artificial intelligence fails to outperform orthopaedic surgeons: A systematic review

How Safety Knowledge Impacts Construction Workers’ Risk Perception: ERP Study
This used a multimethod approach via surveys, behavioural experiments and Event-Related Potential (ERP) experiments, exploring hazard ID and risk perception with subjects with high or low safety knowledge. They also employed EEG. Note. Their use of overestimate or “inaccurate risk level evaluations” is likely to trigger some Extracts: · “During hazard identification, subjects with low safety… Continue reading How Safety Knowledge Impacts Construction Workers’ Risk Perception: ERP Study
Comparing training delivery methods: Impact on learning outcomes and engagement among construction workers
This study compared the effectiveness of different construction safety training protocols: pre-recorded video, lecture, interactive lecture, flipped lecture (pre-recorded video followed by a hands-on activity after two weeks), and interactive lecture with hands-on activity. Engagement levels and short-term learning outcomes, namely hazard recognition skill, high-energy hazard recognition skill (with a focus on SIFs), perception of… Continue reading Comparing training delivery methods: Impact on learning outcomes and engagement among construction workers
