Photographers walking backwards – and falling over (study)

March 21st, 2019

It’s a staple gag for any slapstick movie. Trying for a wider shot, a photographer walks backwards (without looking) and trips over something. Amusing perhaps, but on occasions dangerous too. Odd then, that in the academic literature on safety and ergonomics, there a very few scholarly studies of this ubiquitous syndrome. In fact, there may only be one – in which certified professional ergonomist Dr. Kenneth Nemire, of California, set up a practical experiment to investigate.

Two researchers asked passers-by to photograph them, but then added a request that the building behind them was to be kept in-shot. A third (unseen) researcher was recording the events on video. Later, the videos were analysed to see how many steps the photographers took backwards, and whether they looked behind them*.

The research project revealed that although the majority of the 39 participants did glance behind them before walking backwards, a significant proportion (13%) of them didn’t. Not a high percentage perhaps, but bearing in mind the number of people across the globe taking snaps on any given day, that’s still a high number of potentially amusing (or maybe not so amusing) mishaps.

As Dr Nemire points out ; “Stepping backward without looking is as dangerous as walking forward while wearing a blindfold.”

Predicting the stock market from photographs in the financial-press (new study)

March 18th, 2019

If you’re inclined to make bets on the stock market, you’ll be at a considerable disadvantage if you don’t have a tight grip on so called ‘investor sentiment’ – in other words a reliable way of being able to judge the current ‘mood’ of the market. But, in practice, it’s notoriously difficult to gauge accurately. A team from Missouri State University, US, have come up with a novel method. Why not just analyse photos in the financial press to see if people look happy (or not) ? They’re calling it ‘Photo Sentiment’.

The researchers say that their machine-learning algorithms, which analysed photos in The Economist (that had been published over a period of 10 years) out-performed other more traditional methods by 2.6%.

Photo Sentiment is found to predict short-term return reversal, trading volume and market volatility, and explain flows between equity and money market funds. A trading strategy based on Photo Sentiment outperforms the market index by 2.6% on an annual basis while assuming less risk.”
