In recent years, countries have passed legislation to charge shoppers for each new plastic bag used to encourage them to re-use bags they already own. It’s one of many initiatives to reduce the large quantity of plastic waste that leaks into the natural environment, particularly the oceans, causing ecological damage (see our October 2017 issue for more on this story).
Each year at its conference the Royal Statistical Society (RSS) awards prizes to distinguished individuals for their service to statistics. The prizes include several named medals, each dedicated to a particular aspect of statistics: the Guy medals in gold (first awarded in 1892), silver (1893) and bronze (1936); and the Chambers (1977), Greenfield (1991), Bradford Hill (1994), West (2002) and Howard medals (2015). This year a new name joins the list: the Wood medal, awarded for excellent contributions to economic or social statistics.
