There was mixed news on the economic outlook this week, with higher than expected growth in the US service sector in August, but also an unexpected rise in new applications for unemployment benefits.  Figures released by the Institute for Supply Management showed its non-manufacturing index at 50.6 in August, up from 49.5 in July. A figure above 50 signifies growth.    But the Labor Department said new applications for unemployment insurance rose by 15,000 from the previous week, against expectations of a fourth week of falls.
