How Bots Win Friends and Influence People

Every now and then sociologist Phil Howard writes messages to social media accounts accusing them of being bots. It’s like a Turing test of the state of online political propaganda. “Once in a while a human will come out and say, ‘I’m not a bot,’ and then we have a conversation,” he said at the European Conference for Science Journalists in Copenhagen on June 29.

Trial and error in a Mexican beach town

When general store owner Melchor Villanueva leans on his countertop he can see his whole world under his hands. The counter’s glass surface displays photos of his community: young soccer players, teens in their coming-of-age quince años finest, and bandanna-wearing fishermen. Many descend from survivors of Hurricane Janet, which in 1955 killed a third of the population of Xcalak, a beach town on the Mexico-Belize border, and destroyed the town’s coconut plantations. “It left only sand,” Villanueva recalls.

Ensayo y error en un pueblo playero de México

Cuando el dueño de la tienda de abastos Melchor Villanueva se inclina sobre el mostrador puede ver todo su mundo bajo sus manos.

Muchos descienden de los supervivientes del huracán Janet, que en 1955 mató a una tercera parte de la población de Xcalak, una ciudad costera en la frontera de México con Belice, y destruyó las plantaciones de cocoteros del pueblo. “Acá dejó solo arena”, recuerda Villanueva.

How a New Middleman Might Help Balance Electricity Grids

A few years ago almost two thousand bold households on the Danish island of Bornholm joined a surge pricing experiment run by their electricity utility. It was supposed to empower the utility and consumers with a simple, direct market (“The Smartest, Greenest Grid,” IEEE Spectrum, April 2013).

The EU-funded project, called EcoGrid, won widespread buy-in from residents, who could also earn small payoffs when they reduced demand.  Yet researchers reported last year that they could reduce demand by only 1.2 percent of peak load, despite early predictions of up to 20-percent reductions for so-called virtual power plants. The market model was missing something. Continue reading How a New Middleman Might Help Balance Electricity Grids
