摘要:This report begins by providing an overview of demographic modeling, including the strengths and weaknesses of this technique. Then the elements of the model are developed (e.g., workforce inflows and outflows are defined) and the data set used for estimation of the model--the Survey of Doctorate Recipients (SDR)--is described. Next, the calculation of transition rates for various life changes (e.g., retirement, changing profession) is described. At this point, the model is used to make retroactive projections that are tested against real data from the SDR. Finally, the panel presents recommendations for further work that is needed to develop the model so that it can be used to project the needs for biomedical and behavioral scientists. The report evaluates whether exposure to zinc cadmium sulfide caused adverse health effects in exposed people. This summary report was prepared to give information to concerned citizens about zinc cadmium sulfide, especially about the human health effects that might result from exposure to it. It supplements the technical document and provides answers to commonly asked questions.
