www.sciencemag.org SCIENCE VOL 323 13 FEBRUARY 2009 843 COVER An image of Mare Moscoviense on the lunar farside, taken by the Terrain Camera aboard the SELENE (Kaguya) spacecraft on 17 January 2008. Crater frequency distributions derived from such images yield ages of about 2.5 billion years for several volcanic deposits in this mare, indicating that volcanism on the lunar farside lasted about ...

A look back, a look ahead.

The experts look ahead

The future of integrated electronics is the future of electronics itself. The advantages of integration will bring about a proliferation of electronics, pushing this science into many new areas. Integrated circuits will lead to such wonders as home computers—or at least terminals connected to a central computer—automatic controls for automobiles, and personal portable communications equipment. ...

Adaptive Look-Ahead Planning

We present a new adaptive connectionist planning method. By interaction with an environment a world model is progressively constructed using the backpropagation learning algorithm. The planner constructs a look-ahead plan by iteratively using this model to predict future reinforcements. Future reinforcement is maximized to derive suboptimal plans, thus determining good actions directly from the...

A look back and a look ahead.

The author reviews a series of predictions made more than two decades ago regarding nursing and nursing administration. These concerned the work of nursing, the workers involved in nursing, the environment surrounding practice, and the nurse's role. While many of the forecasts were right on target, others fell short of the mark; both are discussed in light of the challenges facing nurse adminis...
