For those who have not used Power Point (.ppt) presentations before, follow these instructions after you click on the Geralizability Presentation. When the Power Presentation is downloaded you will see the screen for the presentation document, but NOT the presentation itself. You must start the presentation either by hitting the F5 key or going to the menu bar at the top, clicking on "Slide Show" and then clicking on the "View Show" option. When the show appears on the screen, left click once, each time you wish to progress a step further through the presentation. If you want to go back or forward at some point, right click for options, choose the "Go" option, "By Title" option and choose the slide to which you wish to go. If you need to quit, use the same procedure just described, but choose the "End Show" option. To return to the Manuscripts page at the point you left click here.
