Significant improvements were observed immediately in both attitude and knowledge of cancer pain management principles after the 1-day Role Model Workshop. These improvements continued, as determined at 4 and 12 months follow-up. The Role Model Participants were highly motivated to share the learned principles of cancer pain management with other health-care professionals. These results are consistent with other Role Model Programs that both instruct and involve the participants. The Role Model Program is an efficient and effective means of educating health-care professionals in the concepts of cancer pain management.

Railroads have large investments in capital items such as track, trains, and terminals. Optimizing the use of their resources has the potential of enormous payback. Precision Train Control™ (PTC) is an effort to optimize the flow of trains on the line of road in order to increase the return on capital.This paper describes a study whose purpose was to quantify the performance improvements that could be anticipated with PTC. A large-scale simulation involving approximately 1000 miles of track and 700 trains was conducted to produce an estimate of potential improvement.
