In 2014 The University of California, Irvine staged an eight-week MOOC on the sociological, scientific and ethical questions posed by the zombie apocalypse portrayed in AMC’s The Walking Dead.

The well-known manufacturing principle of just-in-time aims to ensure that the right part arrives on the assembly line in the right place and the exact moment it is needed, thus reducing inventory overheads and making for a lean and efficient process. The same principle is being applied to learning for today’s busy professionals, by using algorithms to deliver just the learning content they need – and nothing else – at the time they need it.

According to Douglas Adams in The Hitchhiker’s Guide to the Galaxy, the universe was sneezed out of the nose of a being named the Great Green Arkleseizure. But that theory was only accepted by the Jatravartid people of Viltvodle VI, who lived in perpetual fear of the time they called the Coming of the Great White Handkerchief. Here on Earth, we have our own theories on how the universe began, and thankfully they are a lot less icky and a lot more peer-reviewed.

After regional conflicts, when one side has won, both have given up and gone home, or when there’s nobody left to fight, there is work to do. Post-conflict reconstruction does what it can to clean up the mess, and business has a key role in it.

The task of business in reconstruction is to restore production and distribution systems to energize the economy, create jobs and growth, and positively influence local perceptions.

People who regularly work their gardens often have an aura of contentment about them that non-gardeners envy.
