Prospect and refuge

Following the lively debate last week about the pros and cons of street lighting, prospect, concealment, and entrapment provide a valuable framework for evaluation with the potential to shift us away from the relatively crude brightness measure.

Olympic athlete Chris Boardman MBE offers tips for men in the Guardian: give a woman space, avoid making comments even complimentary, talk to sons and friends about the issue and challenge harassment whenever and wherever you see it – as simple as standing between her and the harasser. – Calling all men: this is what we can do to help women feel safe exercising in the dark

A practical gift to help the older person in your life feel a bit brighter? a lightbulb!

Looking for something practical to brighten up a loved ones’ day over the holidays? a lightbulb might do the trick! This simple study with 21 older adults over 18 days found that a bright cool (500 lux / 6,500k) blue-enhanced light source during the day shifting to a dim warm (100lux, 2,700k) in the evening was enough to boost mood and cognitive function. The bright to dim shift worked but adding the colour temperature shift was significantly better. – Lighting up living spaces to improve mood and cognitive performance in older adults.
