The lack of visibility near earthmoving equipment resulted in six fatalities in U.S. surface mining operations during 2003. These accidents were the result of either a piece of equipment striking another vehicle or worker, or the equipment traveling over the edge of an embankment. Figure 1 is an example of a recent accident that resulted in serious injuries to one worker and fatal injuries to t...

Objective: To evaluate a conceptual framework portraying the factors underlying the intentions of medical students to train abroad. Methods: Eligible subjects were students in the pre-final and final years of medical studies in Lebanon. A survey questionnaire based on the conceptual framework inquired about demographic and educational characteristics, influencing factors, and intentions to trai...

The theory of coupled phase oscillators provides a framework to understand the emergent properties of networks of neuronal oscillators. When the architecture of the network is dominated by short-range connections, the pattern of electrical output is predicted to correspond to traveling plane and rotating waves, in addition to synchronized output. We argue that this theory provides the foundatio...

Three studies confirm the existence of the return trip effect: The return trip often seems shorter than the initial trip, even though the distance traveled and the actual time spent traveling are identical. A pretest shows that people indeed experience a return trip effect regularly, and the effect was found on a bus trip (Study 1), a bicycle trip (Study 2), and when participants watched a vide...

It is shown that in water of #nite depth, the surface pro#le of a periodic traveling wave uniquely determines the corresponding 2ow in the body of the 2uid. This holds for rotational 2ow as long as the vorticity function ( ) satis#es the condition ′( )maxx∈R (x)¡ . This condition is also shown to be sharp. ? 2004 Elsevier Ltd. All rights reserved.

Few studies have focused on the care setting transitions that occur in the last year of life. People living in rural areas may have more difficult care setting transitions and also more moves in the last year of life as health changes occur. A mixed-methods study was conducted to gain an understanding of the number and implications or impact of care setting transitions in the last year of life ...

Recent years have seen accumulating evidence for the proposition that people process time by mapping it onto a linear spatial representation and automatically "project" themselves on an imagined mental time line. Here, we ask whether people can adopt the temporal perspective of another person when travelling through time. To elucidate similarities and differences between time travelling from on...
